Description
Technical Field
The present invention relates to the field of glass protection pastes, and more particularly, to a progressive glass protection paste and a method for manufacturing the same, wherein when the progressive glass protection paste is applied to a portable intelligent electronic device, the progressive glass protection paste effectively protects the portable intelligent electronic device and reduces the influence of the progressive glass protection paste on the operation sensitivity while increasing the edge strength.
Background
Due to the development of technology and the development of electronic industry, portable intelligent electronic devices and related products are now in a vigorous development period, especially in the field and market of intelligent communication and related accessories. It is worth mentioning that, besides the performance of the portable intelligent electronic device, the performance and performance of the portable intelligent electronic device may be greatly affected by the selection of the accessories. Furthermore, in addition to considering the brand, specification and quality of the portable intelligent electronic device, the selection of accessories is also a big problem, and when an accessory with poor quality or poor grade is selected, the usability and high-level performance of the portable intelligent electronic device may be affected.
In particular, the most common accessories in portable intelligent electronic devices are protective cases, glass protective stickers, charging accessories, and the like. The invention aims at improving the existing glass protection paste to solve the problems of the existing glass protection paste. The most common problem of the existing glass protection paste is to protect the screen of the portable intelligent electronic device from being damaged or broken when the glass protection paste is attached to the portable intelligent electronic device, but the thickness of the existing glass protection paste between workshops is about 0.3mm-0.6 mm. According to the study, when the thickness of the patch exceeds 0.45mm, the patch is liable to cause a burden on the touch and vision, and therefore, the use thereof is not recommended. However, the protective effect of the glass protective patch having too small a thickness is not ideal. That is, the thickness of the glass protection sticker affects the operation sensitivity of the portable intelligent electronic device, as well as the screen protection effect. In particular, too thick a glass protective sticker may cause poor or insensitive effects on the special sensing components of the portable intelligent electronic device, such as fingerprint recognition. However, there have been many improvements in the prior applications and the prior art, but these improvements have also had some problems.
In the prior art, the back glue of the glass protection paste is improved. Such as AB glue or UV glue, which is the back glue of the glass protection sticker, is locally thinned to reduce the thickness of the back glue. However, this leads to a problem that the thickness of the glass cannot be reduced, and thus the insensitivity of the glass thickness to a special sensing element, such as fingerprint recognition, cannot be improved. Also, in the prior application, the overall thickness of the adhesive surface on the back of the glass protective sheet is thinned. However, the disadvantage is that the thickness of the whole glue is too thin, so when the glass protection paste is pasted on the screen of the portable intelligent electronic device, the thickness of the glue is uneven when the glass protection paste is pasted on the screen of the portable intelligent electronic device, and bubbles or glue marks are generated when the glass protection paste is pasted on the screen of the portable intelligent electronic device, which further affects the pasting degree of the glass protection paste and the screen, and makes the appearance unattractive. In addition, the problem caused by the thickness of the glass protection paste is not improved by only changing the overall thickness of the back adhesive. Also, in the prior application, there was a region of the glass protector that would be opposite the fingerprint location without the adhesive, i.e., the region would have only the glass protector without the adhesive. However, in such a configuration, the glass protection sticker directly contacts the screen panel, which may scratch the screen, cause newton's rings, and affect the appearance. That is, the glass protection paste without the back adhesive region and the rest glass protection paste with the back adhesive form obvious traces, which seriously affects the appearance and the like.
In the prior application, a through hole or a hole is formed at a position of the glass protection paste corresponding to the special sensing element, so that the glass protection paste does not affect the special sensing element, such as fingerprint recognition or lens operation. That is, the sensing area of the glass protection sticker corresponding to the special sensing assembly is directly dug to form a through hole or a hole. However, such a method affects the integrity of the glass protection sticker, also affects the beauty of the glass protection sticker, is easy to clamp dust, may cause a phenomenon of scratching hands or causing poor hand feeling when in use, and also affects the visual perception of a circle of through holes when viewing a screen. In addition, in the prior art, a through hole or a hole is formed at a position corresponding to the distance sensor. Likewise, such a method affects the integrity of the glass protector, and also affects the aesthetics of the glass protector and causes the phenomenon of easy dust entrapment.
It is worth mentioning that in order to improve the insensitivity phenomenon caused by the glass protection paste, in the prior art, the whole thickness of the whole glass protection paste is directly thinned, for example, the whole thickness is between 0.1 and 0.2 mm. However, such a configuration will affect the overall strength and the edge strength of the glass protection patch, and the user may hit the glass protection patch lightly to cause the glass protection patch to break, which is difficult to achieve the purpose of effectively protecting the portable intelligent electronic device. In addition, there are also previous patents that change the glass protection paste into a thin PET plastic protection paste, and likewise, such a method cannot provide effective protection for portable intelligent electronic devices, such as mobile phones or tablet computers, and the PET plastic protection paste cannot effectively protect the screen when the electronic devices fall down.
As can be understood, people can hardly live far away from the intelligent communication device or the portable intelligent electronic device, and therefore, it is a concern for manufacturers and users about how to improve the use efficiency and the service life of the intelligent communication device or the portable intelligent electronic device. From the above, it can be seen that the glass protection patch of the prior art has proposed various improvements, but the proposed improvements have obvious disadvantages and relatively new problems. However, the present invention clearly improves the above-mentioned problems and provides the best screen protection effect with the least influence on the performance of the smart communication device or the portable smart electronic device.

Referring to fig. 1 to 4, a progressive glass protection patch (100) and a method for manufacturing the same are disclosed, wherein the progressive glass protection patch (100) is suitable for an intelligent communication device or a portable intelligent electronic device (200) to protect a screen of the intelligent communication device or the portable intelligent electronic device while increasing protection strength and increasing sensitivity of use. In particular, the progressive glass protection patch (100) of the invention achieves the purposes of increasing the strength and reducing the influence of the progressive glass protection patch (100) on the operation of the portable intelligent electronic device (200) under the condition of no hole or no through hole.
As shown in fig. 1, the progressive glass protection sticker (100) of the present invention is suitable for the smart communication device or the portable smart electronic device (200) for the purpose of reducing operation and protecting, wherein the portable smart electronic device (200) may be implemented as a smart phone, an IPAD, a tablet computer, which is not a limitation of the present invention. It is worth mentioning that the portable intelligent electronic device (200) comprises a screen liquid crystal panel (201), and the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200).
In addition, the portable intelligent electronic device (200) comprises a control unit, at least one camera module, various electronic components, a fingerprint identifier, a distance sensor and a shell. Since the portable intelligent electronic device (200) is a common electronic product and has a complex structure, the structure and functions of the portable intelligent electronic device are not repeated herein. It is understood that the structure and function of the portable intelligent electronic device (200) do not affect the configuration of the present invention.
In one embodiment of the present invention, the progressive glass protector (100) has an edge (101) and a protector body (102). The edge (101) is positioned at the outer edge of the protection paste body (102), and the edge (101) is connected with the protection paste body (102) in a progressive mode. The protection sticker body (102) corresponds to the touch range of the screen liquid crystal panel (201) of the portable intelligent electronic device (200). The edge (101) is not in the touch range of the screen liquid crystal panel (201) of the portable intelligent electronic device (200). As shown in fig. 2A to 2C, the thickness of the edge (101) is greater than the thickness of the protector body (102). The edge (101) is a closed frame. The protection sticker body (102) is a complete plane. The gradual reduction of the glass thickness from the edge (101) towards the protection paste body (102), i.e. in a gradual manner, will give the progressive glass protection paste (100) better strength and reduced impact on the sensitivity during handling, as well as maintaining aesthetic appearance. It is worth mentioning that the thickness of the edge (101) of the progressive glass protector (100) of the invention can be implemented between 0.2mm and 0.6mm, the thickness of the protector body (102) can be implemented between 0.1mm and 0.55mm, and the thickness is gradually decreased from the edge (101) to the protector body (102), so that the whole progressive glass protector (100) has no obvious step touch. In particular, the edge (101) and the protector body (102) are embodied as bright surfaces. In addition, the edge (101) may also be implemented with a non-bright surface, such as a pattern or coating, to provide different performance requirements, as desired, and is not a limitation of the present invention.
As shown in fig. 2B to 2D, the progressive glass protection patch (100) further includes a back adhesive (30), and the progressive glass protection patch (100) has an upper surface (11), a lower surface (12) and a body surface (13). The back adhesive (30) is arranged on the lower surface (12) and used for enabling the progressive glass protection sticker (100) to be stably attached to the portable intelligent electronic equipment (200). It should be noted that the lower surface (12) may be a plane to be attached to the lcd panel (201) of the portable intelligent electronic device (200), which is not a limitation of the present invention. In other words, when the upper surface of the portable intelligent electronic device (200) is a curved surface, the lower surface (12) of the progressive glass protection sticker (100) will cooperate to form a curved surface. Alternatively, as shown in fig. 2D, the edge (121) of the lower surface (12) may be a curved surface to match the curved surface of the upper surface of the portable intelligent electronic device (200). In addition, the back adhesive (30) is selected from the group consisting of an AB adhesive, a UV water adhesive without a base material, or an optical adhesive, so that the progressive glass protective sticker (100) can be stably adhered to the LCD panel (201) of the portable intelligent electronic device (200) and the purpose of protecting the LCD panel (201) is achieved.
It is worth mentioning that the protection sticker body (102) has a thickness gradually decreasing from the upper surface (11) to the body surface (13), and forms a plane on the body surface (13). Further, the protector body (102) has a body periphery (1021), a body ramp surface (1022), a body inner periphery (1023), and a body bottom surface (1024). The body ramp surface (1022) is smoothly connected between the body periphery (1021) and the body inner periphery (1023). The body inner periphery (1023) is smoothly connected with the body bottom surface (1024). The body periphery (1021) and the body inner periphery (1023) are respectively provided with a smooth arc angle, so that no offset exists between the body slope surface (1022) and the upper surface (11) and the body surface (13). The body ramp surface (1022) is arcuate or planar. The bottom surface (1024) of the body is a plane. The body periphery (1021), the body ramp surface (1022), the body inner periphery (1023), and the body bottom surface (1024) are free of discontinuities.
In the embodiment of the present invention, the progressive glass protection patch (100) may be made of sapphire glass, ceramic glass, microcrystalline glass, aluminosilicate glass, soda-lime glass, etc., which is not a limitation of the present invention.
In the embodiment of the present invention, the best process implementation, as shown in fig. 3, is to make a glass protection paste template (900) form the edge (101) of the closed frame and the complete planar protection paste body (102) by using CNC process, wherein the thickness is gradually reduced from the edge (101) to the protection paste body (102). In other words, the protector body (102) has a smaller thickness than the edge (101). Then, a polishing process is further performed after the CNC process, so that the edge (101) to the protector body (102) becomes a bright surface. In addition, before CNC processing, the area of the protective sticker body (102) of the progressive glass protective sticker (100) to be confirmed in advance is processed by a CNC tool grinding head (800) in a progressive descending manner to form the edge (101) and the protective sticker body (102), and finally the edge (101) and the protective sticker body (102) are polished to be bright. Furthermore, the best complete process of the present invention is to cut the glass substrate into a glass protection template (900), and then perform the above-mentioned CNC and polishing processes, followed by the tempering, nano-coating and gluing processes to complete the fabrication of the entire progressive glass protection sticker (100). It should be noted that the CNC processing method of the present invention is only for illustration, not for the sole purpose, and other processing methods can be used, which is not limited by the present invention.
In addition, the progressive glass protection patch (100) of the present invention may be implemented by other processing methods, wherein the progressive glass protection patch (100) is integrally formed by using the mold (700) as the mold (700). In particular, as shown in fig. 4, the mold (700) can directly form the progressive glass protector (100) having the edge (101) and the protector body (102) by using the mold (700), and then perform a tempering process, a nano-coating process, a gluing process, and the like. In addition, in the same manner of mold processing, the mold (700) may be used to form the progressive glass protection paste (100) as a semi-finished product by using the mold (700), i.e. the progressive glass protection paste is formed into the same shape but the size is not yet in place, then the progressive glass protection paste can be processed by using the CNC processing to reduce the CNC processing time, and then the protection paste body (102) is finished by using the polishing process, and the processes of strengthening treatment, nano coating, gluing and the like are performed subsequently. In other words, the progressive glass protection sticker (100) of the mold (700) that forms the semi-finished product by using the mold (700) requires further CNC machining after the mold is formed.
Fig. 5A to 5E show a modified embodiment of a progressive glass protection patch (100) according to a first preferred embodiment of the present invention, which is configured to reduce the local thickness of the progressive glass protection patch (100) in the area of the electronic sensing element (202) of the portable intelligent electronic device (200).
The portable intelligent electronic device (200) comprises a screen liquid crystal panel (201) and at least one electronic sensing component (202). As shown in fig. 5A to 5B, the electronic sensing component (202) is disposed below the screen lcd panel (201), wherein a user or users can control or operate corresponding functions of the portable intelligent electronic device (200) through the electronic sensing component (202). In other words, the user or the user directly operates the portable intelligent electronic device (200) on the screen liquid crystal panel (201) relative to the electronic sensing component (202) area. The electronic sensing component (202) may be implemented as a fingerprint recognizer, a distance sensor, etc., which is not a limitation of the present invention.
In an embodiment of the present invention, as shown in fig. 5B, the progressive glass protection sticker (100) of the present invention is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200), so as to protect the screen liquid crystal panel (201) and increase the operation sensitivity. In particular, the progressive glass protection sticker (100) has an edge (101), a protection sticker body (102) and at least one progressive sensing area (103), wherein the protection sticker body (102) gradually reduces in thickness from the edge (101) and forms a plane in a touch area opposite to the screen liquid crystal panel (201), and the progressive sensing area (103) is located on the protection sticker body (102) and is disposed in a position opposite to the electronic sensing component (202). The size of the protection sticker body (102) is slightly equal to that of the screen liquid crystal panel (201) of the portable intelligent electronic device (200). In other words, the protection sticker main body (102) corresponds to the touch range of the screen liquid crystal panel (201). The edge (101) is not in the touch range of the screen liquid crystal panel (201). Further, the edge (101) will increase the strength of the progressive glass protection patch (100). The protective sticker body (102) can reduce the influence of the progressive glass protective sticker (100) on the touch operation of the screen liquid crystal panel (201). The progressive sensing region (103) will reduce the impact of the progressive glass protection patch (100) on the electronic sensing component (202) when in operation. In addition, as shown in fig. 5B, when the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200), the progressive sensing area (103) is located relative to the electronic sensing component (202). Furthermore, the progressive sensing area (103) is disposed on the protection sticker body (102) according to the relative position of the electronic sensing component (202) under the screen liquid crystal panel (201), wherein the progressive sensing area (103) has the advantages of being thin, smooth, attractive, free of dust and scratching, and the like. Therefore, when the electronic sensing component (202) is operated through the progressive sensing region (103), the influence of a glass panel on the electronic sensing component (202) is reduced, and the electronic sensing component has the advantage of attractive appearance. It is worth mentioning that the progressive sensing region (103) is arranged in a progressive blind via.
In an embodiment of the present invention, the progressive sensing area (103) is a blind hole progressive arrangement, wherein the periphery (1031) may be square, rectangular, circular, elliptical, trapezoidal, unequal-edge, etc., and is tapered from the periphery (1031) to the inside in a funnel-shaped or arc-shaped or plane-inclined manner, while decreasing the thickness from top to bottom, which allows setting to make the sensing of the electronic sensing component (202), i.e. the fingerprint sensor or the distance sensor, faster and more stable.
In the embodiment of the present invention, as shown in fig. 5C to 5E, the progressive glass protection patch (100) further includes a back adhesive (30), and the progressive glass protection patch (100) has an upper surface (11), a lower surface (12) and a body surface (13). The back adhesive (30) is arranged on the lower surface (12) and used for enabling the progressive glass protection sticker (100) to be stably attached to the portable intelligent electronic equipment (200). The progressive sensing zone (103) is a progressive gradual slope reduction of the thickness of the patch body (102) from the body surface (13) to the lower surface (12), wherein the thinnest thickness may be 0.1 mm. It can also be said that the periphery (1031) of the progressive sensing region (103) is concave inwardly, i.e. from the body surface (13) to the lower surface (12). More specifically, the progressive sensing zone (103) has a periphery (1031), a sloped surface (1032) and a bottom surface (1033), wherein the periphery (1031) is smoothly connected to the sloped surface (1032), and the sloped surface (1032) is smoothly connected to the bottom surface (1033), i.e., the sloped surface (1032) is smoothly connected between the periphery (1031) and the bottom surface (1033). The periphery (1031) is located on the body surface (13), wherein the area size and location of the periphery (1031) is set in accordance with the electronic sensing component (202). In particular, the periphery (1031) has a smooth radiused angle so that there is no break between the ramp surface (1032) and the body surface (13). The ramp surface (1032) slopes inwardly and downwardly from the periphery (1031), wherein the slope may be curved or flat, which is not a limitation of the present invention, and is mainly characterized in that no discontinuity is observed when viewed from the external appearance. The bottom surface (1033) is an arc or a plane, and is smoothly connected with the slope surface (1032) so that the phenomenon of break does not occur. Further, fig. 5C shows that the outer periphery (1031) has a smooth arc angle, and the slope surface (1032) and the bottom surface (1033) are arc surfaces. Fig. 5D shows that the periphery (1031) has a smooth arc angle, the sloped surface (1032) is a plane, and the bottom surface (1033) is an arc surface. Fig. 5E shows that the outer periphery (1031) has a smooth rounded corner, and the sloped surface (1032) and the bottom surface (1033) are flat surfaces.
It is worth mentioning that the thickness of the progressive sensing zone (103) of the progressive glass protector (100) of the invention can be progressively increased from 0.2mm to 0.01mm, and that the progressive glass protector (100) has no discontinuity touch throughout.
In the embodiment of the present invention, the progressive glass protection patch (100) may be made of sapphire glass, ceramic glass, microcrystalline glass, aluminosilicate glass, soda-lime glass, etc., which is not a limitation of the present invention.
In the embodiment of the present invention, the best process implementation is to form the edge (101) of the closed frame, the completely planar protection sticker body (102) and the progressive sensing region (103) of the region on a glass protection sticker template (900) by using a CNC process to increase the strength and reduce the thickness of the protection sticker body (102) and the progressive sensing region (103). And further performing a polishing process after the CNC process to make the edge (101), the protection sticker body (102) and the progressive sensing area (103) bright. Before CNC machining, the positions of the protective sticker body (102) and the progressive sensing area (103) of the progressive glass protective sticker (100) to be confirmed are firstly confirmed, then a CNC tool grinding head (800) is used for machining the glass protective sticker template (900) in a gradual descending mode to form the protective sticker body (102) and the progressive sensing area (103), and finally the protective sticker body and the progressive sensing area are polished to be a bright surface. Furthermore, the best complete process of the present invention is to form a glass protection template (900) by cutting the glass substrate, then perform the above-mentioned CNC and polishing processes, and then perform the toughening, nano-coating and gluing processes to complete the fabrication of the whole progressive glass protection sticker (100). It should be noted that the CNC processing method of the present invention is only for illustration, not for the sole purpose, and other processing methods can be used, which is not limited by the present invention.
In addition, the progressive glass protection patch (100) of the present invention may be implemented by other processing methods, wherein the progressive glass protection patch (100) is integrally formed by using the mold (700) as the mold (700). In particular, the mold (700) may directly form the progressive glass protection patch (100) having the edge (101), the protection patch body (102) and the progressive sensing region (103) by using the mold (700), and then perform a toughening process, a nano-coating process, a gluing process, and the like. In addition, in the same manner of mold processing, the mold (700) may be used to form the semi-finished progressive glass protection sticker (100) by using the mold (700), and then the manufacturing process may be completed by using CNC and polishing processes, and similarly, the processes of strengthening treatment, nano coating, gluing, and the like may be performed subsequently. In particular, the progressive glass protector (100) in which the mould (700) forms a semi-finished product with the mould (700) requires, after moulding, further CNC machining to form the edge (101), the protector body (102) and the progressive sensing zone (103).
Referring to fig. 6 to 9, a progressive glass protection patch (100) and a method for manufacturing the same according to a second preferred embodiment of the present invention are disclosed, wherein the progressive glass protection patch (100) is suitable for smart communication devices or portable smart electronic devices (200) to protect screens of the smart communication devices or portable smart electronic devices while increasing protection strength and increasing sensitivity. In particular, the progressive glass protection patch (100) of the invention achieves the purposes of increasing the strength and reducing the influence of the progressive glass protection patch (100) on the operation of the portable intelligent electronic device (200) under the condition of no hole or no through hole.
As shown in fig. 6, the progressive glass protection sticker (100) of the present invention is suitable for the smart communication device or the portable smart electronic device (200) for the purpose of reducing operation and protecting, wherein the portable smart electronic device (200) may be implemented as a smart phone, an IPAD, a tablet computer, which is not a limitation of the present invention. It is worth mentioning that the portable intelligent electronic device (200) comprises a screen liquid crystal panel (201), and the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200). In addition, the portable intelligent electronic device (200) comprises a control unit, at least one camera module, various electronic components, a fingerprint identifier, a distance sensor and a shell. Since the portable intelligent electronic device (200) is a common electronic product and has a complex structure, the structure and functions of the portable intelligent electronic device are not repeated herein. It is understood that the structure and function of the portable intelligent electronic device (200) do not affect the configuration of the present invention.
In one embodiment of the present invention, the progressive glass protector (100) has an edge (101), a protector body (102), and a planar sensing region (104). The edge (101) connects the patch body (102) and the planar sensing region (104) in a progressive manner. The protective sticker body (102) and the plane sensing area (104) form the same plane. The plane sensing area (104) enables the edge (101) to form a gap, namely the edge (101) is an open frame. It is worth mentioning that the planar sensing region (104) is opposite to the electronic components of the portable intelligent electronic device (200), such as a lens, a speaker, etc. In particular, the planar sensing zone (104) may be used to protect electronic components without affecting the use of the electronic components.
In addition, the protection sticker body (102) corresponds to the touch range of the screen liquid crystal panel (201) of the portable intelligent electronic device (200).

The protective sticker body (102) and the plane sensing area (104) are a complete plane. The gradual reduction of the glass thickness from the edge (101) towards the protector body (102) and the planar sensing area (104), i.e. in a gradual manner, will give the progressive glass protector (100) better strength and reduced sensitivity in operation, as well as aesthetic appearance. It is worth mentioning that the thickness of the edge (101) of the progressive glass protector (100) of the present invention may be implemented as 0.2mm to 0.6mm, the thickness of the protector body (102) and the planar sensing area (104) may be implemented as 0.1mm to 0.55mm, and the thickness is gradually decreased from the edge (101) to the protector body (102) and the planar sensing area (104), so that the progressive glass protector (100) has no distinct cross-touch.
As shown in fig. 7B, the progressive glass protector (100) further comprises a back adhesive (30), and the progressive glass protector (100) has an upper surface (11), a lower surface (12) and a body surface (13). The back adhesive (30) is arranged on the lower surface (12) and used for enabling the progressive glass protection sticker (100) to be stably attached to the portable intelligent electronic equipment (200). It should be noted that the lower surface (12) may be a plane to be attached to the lcd panel (201) of the portable intelligent electronic device (200), which is not a limitation of the present invention. In other words, when the upper surface of the portable intelligent electronic device (200) is a curved surface, the lower surface (12) of the progressive glass protection sticker (100) will cooperate to form a curved surface. Alternatively, as shown in fig. 7C, the edge (121) of the lower surface (12) may be a curved surface to match the curved surface of the upper surface of the portable intelligent electronic device (200). In addition, the back adhesive (30) is selected from the group consisting of an AB adhesive, a UV water adhesive without a base material, or an optical adhesive, so that the progressive glass protective sticker (100) can be stably adhered to the LCD panel (201) of the portable intelligent electronic device (200) and the purpose of protecting the LCD panel (201) is achieved.
It is worth mentioning that the protection sticker body (102) has a thickness gradually decreasing from the upper surface (11) to the body surface (13), and forms a plane on the body surface (13). Further, the protector body (102) has a body periphery (1021), a body ramp surface (1022), a body inner periphery (1023), and a body bottom surface (1024). The body ramp surface (1022) is smoothly connected between the body periphery (1021) and the body inner periphery (1023).

The body periphery (1021) and the body inner periphery (1023) are respectively provided with a smooth arc angle, so that no offset exists between the body slope surface (1022) and the upper surface (11) and the body surface (13). The body ramp surface (1022) is arcuate or planar. The bottom surface (1024) of the body is a plane.

In the embodiment of the present invention, the progressive glass protection patch (100) may be made of sapphire glass, ceramic glass, microcrystalline glass, aluminosilicate glass, soda-lime glass, etc., which is not a limitation of the present invention.
In an embodiment of the present invention, the best process implementation is shown in fig. 8, wherein a glass protector template (900) is formed by CNC process to form the edge (101) of the open frame and the complete planar protector body (102) and the planar sensing region (104), wherein the thickness is gradually reduced from the edge (101) to the space between the protector body (102) and the planar sensing region (104). In other words, the thickness of the patch body (102) and of the planar sensing area (104) is smaller than the thickness of the edge (101). Then, a polishing process is further performed after the CNC process, so that the edge (101), the protection sticker body (102) and the planar sensing region (104) are all bright. In addition, before CNC processing, the protective sticker body (102) and the plane sensing area (104) of the progressive glass protective sticker (100) to be confirmed are processed by a CNC tool grinding head (800) with progressive gradual descending to form the edge (101), the protective sticker body (102) and the plane sensing area (104), and finally the edge (101), the protective sticker body (102) and the plane sensing area (104) are polished to be bright. Furthermore, the best complete process of the present invention is to cut the glass substrate into a glass protection template (900), and then perform the above-mentioned CNC and polishing processes, followed by the tempering, nano-coating and gluing processes to complete the fabrication of the entire progressive glass protection sticker (100). It should be noted that the CNC processing method of the present invention is only for illustration, not for the sole purpose, and other processing methods can be used, which is not limited by the present invention.
In addition, the progressive glass protection patch (100) of the present invention may be implemented by other processing methods, wherein the progressive glass protection patch (100) is integrally formed by using the mold (700) as the mold (700). In particular, as shown in fig. 9, the mold (700) can directly form the progressive glass protector (100) having the edge (101), the protector body (102) and the plane sensing region (104) by using the mold (700), and then perform a toughening process, a nano-coating process, a gluing process, and the like. In addition, in the same manner of mold processing, the mold (700) may be used to form the progressive glass protection sticker (100) as a semi-finished product by using the mold (700), i.e., the progressive glass protection sticker (100) is formed in the same shape but has not yet been formed in the right position, and then may be subjected to CNC processing to reduce the CNC processing time, and then may be subjected to polishing processing to complete the manufacturing, and similarly, may be subjected to strengthening treatment, nano-coating, gluing, and the like. In other words, the progressive glass protection sticker (100) of the mold (700) that forms the semi-finished product by using the mold (700) requires further CNC machining after the mold is formed. It is understood that the mold (700) may form a finished product or a semi-finished product by using the mold cavity (701) of the mold (700) to make the progressive glass protection sticker (100), which may be controlled by the mold cavity (701). The actual conditions are adjusted during the manufacturing process, which is not a limitation of the present invention.
Fig. 10A to 10B show a modified embodiment of a progressive glass protection patch (100) according to a second preferred embodiment of the present invention, which is to reduce the local thickness of the progressive glass protection patch (100) in the area of the electronic sensing element (202) of the portable intelligent electronic device (200).
In the embodiment of the invention, the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200), so that the screen liquid crystal panel (201) is protected and the operation sensitivity is improved. In particular, the progressive glass protection sticker (100) has an edge (101), a protection sticker body (102), at least one progressive sensing area (103), and a plane sensing area (104), wherein the protection sticker body (102) and the plane sensing area (104) are gradually reduced in thickness from the edge (101) and form a plane in a touch area opposite to the screen liquid crystal panel (201), and the progressive sensing area (103) is located on the protection sticker body (102) and is arranged in a position opposite to the electronic sensing component (202). The plane sensing area (104) enables the edge (101) to form a gap, namely the edge (101) is an open frame. The size of the protection sticker body (102) is slightly equal to that of the screen liquid crystal panel (201) of the portable intelligent electronic device (200). In other words, the protection sticker main body (102) corresponds to the touch range of the screen liquid crystal panel (201). The edge (101) is not in the touch range of the screen liquid crystal panel (201). Further, the edge (101) will increase the strength of the progressive glass protection patch (100). The protective sticker body (102) can reduce the influence of the progressive glass protective sticker (100) on the touch operation of the screen liquid crystal panel (201). The progressive sensing region (103) will reduce the impact of the progressive glass protection patch (100) on the electronic sensing component (202) when in operation. In addition, when the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200), the progressive sensing area (103) is located relative to the electronic sensing component (202). The progressive sensing region (103) has the advantages of being thin, smooth, attractive, free of dust and scratching hands and the like. The progressive sensing region (103) is arranged by adopting progressive blind holes.
In an embodiment of the present invention, the progressive sensing area (103) is a blind hole progressive arrangement, wherein the periphery (1031) may be square, rectangular, circular, elliptical, trapezoidal, unequal-edge, etc., and is tapered from the periphery (1031) to the inside in a funnel-shaped or arc-shaped or plane-inclined manner, while decreasing the thickness from top to bottom, which allows setting to make the sensing of the electronic sensing component (202), i.e. the fingerprint sensor or the distance sensor, faster and more stable.
In an embodiment of the present invention, as shown in fig. 10B, the progressive glass protection patch (100) further comprises a back adhesive (30), and the progressive glass protection patch (100) has an upper surface (11), a lower surface (12) and a body surface (13). The back adhesive (30) is arranged on the lower surface (12) and used for enabling the progressive glass protection sticker (100) to be stably attached to the portable intelligent electronic equipment (200). The progressive sensing zone (103) is a progressive gradual slope reduction of the thickness of the patch body (102) from the body surface (13) to the lower surface (12), wherein the thinnest thickness may be 0.01 mm. It can also be said that the periphery (1031) of the progressive sensing region (103) is concave inwardly, i.e. from the body surface (13) to the lower surface (12). More specifically, the progressive sensing zone (103) has a periphery (1031), a sloped surface (1032) and a bottom surface (1033), wherein the periphery (1031) is smoothly connected to the sloped surface (1032), and the sloped surface (1032) is smoothly connected to the bottom surface (1033), i.e., the sloped surface (1032) is smoothly connected between the periphery (1031) and the bottom surface (1033). The periphery (1031) is located on the body surface (13), wherein the area size and location of the periphery (1031) is set in accordance with the electronic sensing component (202). In particular, the periphery (1031) has a smooth radiused angle so that there is no break between the ramp surface (1032) and the body surface (13). The ramp surface (1032) slopes inwardly and downwardly from the periphery (1031), wherein the slope may be curved or flat, which is not a limitation of the present invention, and is mainly characterized in that no discontinuity is observed when viewed from the external appearance. The bottom surface (1033) is an arc or a plane, and is smoothly connected with the slope surface (1032) so that the phenomenon of break does not occur. It is worth mentioning that the thickness of the progressive sensing zone (103) of the progressive glass protector (100) of the invention can be progressively increased from 0.2mm to 0.01mm, and that the progressive glass protector (100) has no discontinuity touch throughout.
In the embodiment of the present invention, the progressive glass protection patch (100) may be made of sapphire glass, ceramic glass, microcrystalline glass, aluminosilicate glass, soda-lime glass, etc., which is not a limitation of the present invention.
In the embodiment of the present invention, the best process implementation is to form the edge (101), the complete planar protection sticker body (102) and the planar sensing region (104) of the closed frame, and the progressive sensing region (103) of the sum region on a glass protection sticker template (900) by using a CNC process to increase the strength and reduce the thickness of the protection sticker body (102), the planar sensing region (104) and the progressive sensing region (103). And further performing a polishing process after the CNC process to make the edge (101), the protection sticker body (102), the planar sensing region (104) and the progressive sensing region (103) become bright surfaces. Before CNC machining, the positions of the protective sticker body (102), the plane sensing area (104) and the progressive sensing area (103) of the progressive glass protective sticker (100) to be confirmed are determined in advance, then a CNC tool grinding head (800) is used for machining the glass protective sticker template (900) in a progressive descending mode to form the protective sticker body (102), the plane sensing area (104) and the progressive sensing area (103), and finally the protective sticker body, the plane sensing area (104) and the progressive sensing area (103) are polished to be a bright surface. Furthermore, the best complete process of the present invention is to form a glass protection template (900) by cutting the glass substrate, then perform the above-mentioned CNC and polishing processes, and then perform the toughening, nano-coating and gluing processes to complete the fabrication of the whole progressive glass protection sticker (100). It should be noted that the CNC processing method of the present invention is only for illustration, not for the sole purpose, and other processing methods can be used, which is not limited by the present invention.
In addition, the progressive glass protection patch (100) of the present invention may be implemented by other processing methods, wherein the progressive glass protection patch (100) is integrally formed by using the mold (700) as the mold (700). In particular, the mold (700) may directly form the progressive glass protection patch (100) having the edge (101), the protection patch body (102) and the progressive sensing region (103) by using the mold (700), and then perform a toughening process, a nano-coating process, a gluing process, and the like. In addition, in the same manner of mold processing, the mold (700) may be used to form the semi-finished progressive glass protection sticker (100) by using the mold (700), and then the manufacturing process may be completed by using CNC and polishing processes, and similarly, the processes of strengthening treatment, nano coating, gluing, and the like may be performed subsequently.
Referring to fig. 11A to 13, a progressive glass protection patch (100) and a method for manufacturing the same are disclosed, wherein the progressive glass protection patch (100) is suitable for smart communication devices or portable smart electronic devices (200) to protect screens of the smart communication devices or portable smart electronic devices while increasing protection strength and not affecting performance of external electronic components. In particular, the progressive glass protection patch (100) of the embodiment takes an operable touch screen range of the portable intelligent electronic device (200) as an external dimension, wherein the progressive glass protection patch (100) has better strength and does not affect the operation effect of the portable intelligent electronic device (200).
As shown in fig. 11A, the progressive glass protection patch (100) of the present invention is suitable for the smart communication device or the portable smart electronic device (200) for the purpose of reducing operation and protecting, wherein the portable smart electronic device (200) can be implemented as a smart phone, an IPAD, a tablet computer, which is not limited by the present invention. It is worth mentioning that the portable intelligent electronic device (200) comprises a screen liquid crystal panel (201), and the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200). In particular, the external dimension of the progressive glass protection sticker (100) is approximate to the operable touch range of the screen liquid crystal panel (201). In addition, the portable intelligent electronic device (200) comprises a control unit, at least one camera module, various electronic components, a fingerprint identifier, a distance sensor, a shell and the like. The portable intelligent electronic device (200) is a common electronic product and has a complex structure, and the structure and the function of the portable intelligent electronic device are not repeated herein.
In one embodiment of the present invention, as shown in fig. 11B, the progressive glass protector (100) has an edge (101), a protector body (102) and an electronic component opening area (105). The edge (101) connects the protector body (102) in a progressive manner. The electronic component opening area (105) forms the progressive glass protective patch (100) into an opening, wherein the edge (101) surrounds the protective patch body (102) and the electronic component opening area (105), or forms a closed border. That is, the edge (101) forms a closed loop along the protector body (102) and the electronic component opening area (105). The electronic component opening area (105) is opposite to exposed electronic components of the portable intelligent electronic device (200), such as a lens, a loudspeaker and the like. It should be noted that, as shown in fig. 11A, the front lens and the speaker of the portable intelligent electronic device (200) are disposed right above the portable intelligent electronic device (200). Thus, the electronic component opening area (105) is arranged opposite to and directly above the progressive glass protection patch (100). However, this is not the only setting position. In other words, the location of the electronic component opening area (105) is arranged relative to the exposed electronic components of the portable intelligent electronic device (200).
In addition, the protection sticker body (102) corresponds to the touch range of the screen liquid crystal panel (201) of the portable intelligent electronic device (200). The edge (101) is not in the touch range of the screen liquid crystal panel (201) of the portable intelligent electronic device (200), namely the edge (101) does not influence the operation of the screen liquid crystal panel (201). The thickness of the edge (101) is greater than the thickness of the patch body (102) and the planar sensing region (104). The edge (101) is a closed frame. The protection sticker body (102) is a complete plane. The gradual reduction of the glass thickness from the edge (101) towards the protection paste body (102), i.e. in a gradual manner, will give the progressive glass protection paste (100) better strength and reduced impact on the sensitivity during handling, as well as maintaining aesthetic appearance. It is worth mentioning that the thickness of the edge (101) of the progressive glass protector (100) of the invention can be implemented between 0.2mm and 0.6mm, the thickness of the protector body (102) can be implemented between 0.1mm and 0.55mm, and the thickness is progressively reduced from the edge (101) to the protector body (102), so that the progressive glass protector (100) has no obvious break touch.
As shown in fig. 11C, the progressive glass protector (100) further comprises a back adhesive (30), and the progressive glass protector (100) has an upper surface (11), a lower surface (12) and a body surface (13). The back adhesive (30) is arranged on the lower surface (12) and used for enabling the progressive glass protection sticker (100) to be stably attached to the portable intelligent electronic equipment (200). It should be noted that the lower surface (12) may be a plane to be attached to the lcd panel (201) of the portable intelligent electronic device (200), which is not a limitation of the present invention. In other words, when the upper surface of the portable intelligent electronic device (200) is a curved surface, the lower surface (12) of the progressive glass protection sticker (100) will cooperate to form a curved surface. Alternatively, as shown in fig. 11D, the edge (121) of the lower surface (12) may be a curved surface to match the curved surface of the upper surface of the portable intelligent electronic device (200). In addition, the back adhesive (30) is selected from the group consisting of an AB adhesive, a UV water adhesive without a base material, or an optical adhesive, so that the progressive glass protective sticker (100) can be stably adhered to the LCD panel (201) of the portable intelligent electronic device (200) and the purpose of protecting the LCD panel (201) is achieved.
It is worth mentioning that the protection sticker body (102) has a thickness gradually decreasing from the upper surface (11) to the body surface (13), and forms a plane on the body surface (13). Further, the protector body (102) has a body periphery (1021), a body ramp surface (1022), a body inner periphery (1023), and a body bottom surface (1024). The body ramp surface (1022) is smoothly connected between the body periphery (1021) and the body inner periphery (1023). The body inner periphery (1023) is smoothly connected with the body bottom surface (1024). The body periphery (1021) and the body inner periphery (1023) are respectively provided with a smooth arc angle, so that no offset exists between the body slope surface (1022) and the upper surface (11) and the body surface (13). The body ramp surface (1022) is arcuate or planar. The bottom surface (1024) of the body is a plane. The body periphery (1021), the body ramp surface (1022), the body inner periphery (1023), and the body bottom surface (1024) are free of discontinuities.
In the embodiment of the present invention, the progressive glass protection patch (100) may be made of sapphire glass, ceramic glass, microcrystalline glass, aluminosilicate glass, soda-lime glass, etc., which is not a limitation of the present invention.
In the embodiment of the present invention, the best process implementation is shown in fig. 12, wherein a glass protection template (900) is formed to form the edge (101) of the closed frame and the complete planar protection sticker body (102) and the electronic component opening area (105) by CNC process, wherein the thickness is gradually reduced from the edge (101) to the protection sticker body (102). In other words, the thickness of the protector body (102) is smaller than the thickness of the edge (101). Then, a polishing process is further performed after passing through the CNC process, so that the edge (101) and the protector body (102) become a bright surface. In addition, before CNC machining, the areas of the protective sticker body (102) and the electronic component opening area (105) of the progressive glass protective sticker (100) to be confirmed are machined by a CNC tool grinding head (800) in a progressive gradual slope descending manner to form the edge (101), the protective sticker body (102) and the electronic component opening area (105), and finally the edge (101) and the protective sticker body (102) are polished to be bright surfaces by a polishing process. Furthermore, the best complete process of the present invention is to cut the glass substrate into a glass protection template (900), and then perform the above-mentioned CNC and polishing processes, followed by the tempering, nano-coating and gluing processes to complete the fabrication of the entire progressive glass protection sticker (100). In particular, the glass protection stencil (900) may have the electronic component opening area (105), or no electronic component opening area (105). That is, the electronic component opening area (105) may be previously formed in the glass protective pasting template (900) or may be machined by the CNC tool grinding head (800), which is not a limitation of the present invention. In addition, the CNC processing method is only illustrated, not only, but also other processing methods can be utilized, which is not limited by the present invention.
In addition, the progressive glass protection patch (100) of the present invention may be implemented by other processing methods, wherein the progressive glass protection patch (100) is integrally formed by using the mold (700) as the mold (700). In particular, as shown in fig. 13, the mold (700) can directly form the progressive glass protector (100) having the edge (101), the protector body (102) and the electronic component opening area (105) completely by using the mold (700), and then perform a tempering process, a nano-coating process, a gluing process, and the like. In addition, in the same manner of mold processing, the mold (700) may be used to form the progressive glass protection sticker (100) as a semi-finished product by using the mold (700), i.e., the progressive glass protection sticker (100) is formed in the same shape but has not yet been formed in the right position, and then may be subjected to CNC processing to reduce the CNC processing time, and then may be subjected to polishing processing to complete the manufacturing, and similarly, may be subjected to strengthening treatment, nano-coating, gluing, and the like. In other words, the progressive glass protection sticker (100) of the mold (700) that forms the semi-finished product by using the mold (700) requires further CNC machining after the mold is formed. It is understood that the mold (700) may form a finished product or a semi-finished product by using the mold cavity (701) of the mold (700) to make the progressive glass protection sticker (100), which may be controlled by the mold cavity (701). The actual conditions are adjusted during the manufacturing process, which is not a limitation of the present invention.
Fig. 14A to 14B show a variant embodiment of a progressive glass protection patch (100) according to a third preferred embodiment of the present invention, which is to reduce the local thickness of the progressive glass protection patch (100) in the region of the electronic sensing element (202) of the portable intelligent electronic device (200).
In the embodiment of the invention, the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200), so that the screen liquid crystal panel (201) is protected and the operation sensitivity is improved. In particular, the progressive glass protection sticker (100) has an edge (101), a protection sticker body (102), at least one progressive sensing area (103), and an electronic device opening area (105), wherein the protection sticker body (102) is gradually reduced in thickness from the edge (101) and forms a plane in a touch area opposite to the screen liquid crystal panel (201), and the progressive sensing area (103) is located on the protection sticker body (102) and is disposed in a position opposite to the electronic sensing device (202).
The electronic component opening area (105) forms the progressive glass protection sticker (100) into an opening, wherein the edge (101) is a closed frame. The electronic component opening area (105) is opposite to exposed electronic components of the portable intelligent electronic device (200), such as a lens, a loudspeaker and the like. The size of the protection sticker body (102) is slightly equal to that of the screen liquid crystal panel (201) of the portable intelligent electronic device (200). In other words, the protection sticker main body (102) corresponds to the touch range of the screen liquid crystal panel (201). The edge (101) is not in the touch range of the screen liquid crystal panel (201). Further, the edge (101) will increase the strength of the progressive glass protection patch (100). The protective sticker body (102) can reduce the influence of the progressive glass protective sticker (100) on the touch operation of the screen liquid crystal panel (201). The progressive sensing region (103) will reduce the impact of the progressive glass protection patch (100) on the electronic sensing component (202) when in operation. The electronic component opening area (105) will keep the operation of the exposed electronic components of the portable intelligent electronic device (200) unaffected. In addition, when the progressive glass protection sticker (100) is attached to the screen liquid crystal panel (201) of the portable intelligent electronic device (200), the progressive sensing area (103) is located relative to the electronic sensing component (202). The progressive sensing region (103) has the advantages of being thin, smooth, attractive, free of dust and scratching hands and the like. The progressive sensing region (103) is arranged by adopting progressive blind holes.
In an embodiment of the present invention, the progressive sensing area (103) is a blind hole progressive arrangement, wherein the periphery (1031) may be square, rectangular, circular, elliptical, trapezoidal, unequal-edge, etc., and is tapered from the periphery (1031) to the inside in a funnel-shaped or arc-shaped or plane-inclined manner, while decreasing the thickness from top to bottom, which allows setting to make the sensing of the electronic sensing component (202), i.e. the fingerprint sensor or the distance sensor, faster and more stable.
In an embodiment of the present invention, as shown in fig. 14B, the progressive glass protection patch (100) further comprises a back adhesive (30), and the progressive glass protection patch (100) has an upper surface (11), a lower surface (12) and a body surface (13). The back adhesive (30) is arranged on the lower surface (12) and used for enabling the progressive glass protection sticker (100) to be stably attached to the portable intelligent electronic equipment (200). The progressive sensing zone (103) is a gradual reduction in the thickness of the body (10) from the body surface (13) to the lower surface (12), wherein the thinnest thickness may be 0.01 mm. It can also be said that the periphery (1031) of the progressive sensing region (103) is concave inwardly, i.e. from the body surface (13) to the lower surface (12). More specifically, the progressive sensing zone (103) has a periphery (1031), a sloped surface (1032) and a bottom surface (1033), wherein the periphery (1031) is smoothly connected to the sloped surface (1032), and the sloped surface (1032) is smoothly connected to the bottom surface (1033), i.e., the sloped surface (1032) is smoothly connected between the periphery (1031) and the bottom surface (1033). The periphery (1031) is located on the body surface (13), wherein the area size and location of the periphery (1031) is set in accordance with the electronic sensing component (202). In particular, the periphery (1031) has a smooth radiused angle so that there is no break between the ramp surface (1032) and the body surface (13). The ramp surface (1032) slopes inwardly and downwardly from the periphery (1031), wherein the slope may be curved or flat, which is not a limitation of the present invention, and is mainly characterized in that no discontinuity is observed when viewed from the external appearance. The bottom surface (1033) is an arc or a plane, and is smoothly connected with the slope surface (1032) so that the phenomenon of break does not occur. It is worth mentioning that the thickness of the progressive sensing zone (103) of the progressive glass protector (100) of the invention can be progressively increased from 0.2mm to 0.01mm, and that the progressive glass protector (100) has no discontinuity touch throughout.
In the embodiment of the present invention, the progressive glass protection patch (100) may be made of sapphire glass, ceramic glass, microcrystalline glass, aluminosilicate glass, soda-lime glass, etc., which is not a limitation of the present invention.
In the embodiment of the present invention, the best process implementation is to form the edge (101) of the closed frame, the completely planar protection sticker body (102), and the electronic component opening area and the progressive sensing area (103) on a glass protection sticker template (900) by using a CNC process to increase the strength and reduce the thickness of the protection sticker body (102) and the progressive sensing area (103). And further performing a polishing process after the CNC process to make the edge (101), the protection sticker body (102) and the progressive sensing area (103) bright. Before CNC machining, the positions of the protective sticker body (102), the electronic component opening area (105) and the progressive sensing area (103) of the progressive glass protective sticker (100) to be confirmed are determined in advance, then a CNC tool grinding head (800) is used for machining the glass protective sticker template (900) in a progressive descending mode to form the protective sticker body (102), the electronic component opening area (105) and the progressive sensing area (103), and finally a polishing process is used for changing the protective sticker body, the electronic component opening area (105) and the progressive sensing area (103) into a bright surface. Furthermore, the best complete process of the present invention is to form a glass protection template (900) by cutting the glass substrate, then perform the above-mentioned CNC and polishing processes, and then perform the toughening, nano-coating and gluing processes to complete the fabrication of the whole progressive glass protection sticker (100). It should be noted that the CNC processing method of the present invention is only for illustration, not for the sole purpose, and other processing methods can be used, which is not limited by the present invention.
In addition, the progressive glass protection patch (100) of the present invention may be implemented by other processing methods, wherein the progressive glass protection patch (100) is integrally formed by using the mold (700) as the mold (700). In particular, the mold (700) can directly form the progressive glass protection patch (100) having the edge (101), the protection patch body (102), the electronic component opening region (105) and the progressive sensing region (103) by using the mold (700), and then perform a toughening process, a nano-coating process, a gluing process, and the like. In addition, in the same manner of mold processing, the mold (700) may be used to form the semi-finished progressive glass protection sticker (100) by using the mold (700), and then the manufacturing process may be completed by using CNC and polishing processes, and similarly, the processes of strengthening treatment, nano coating, gluing, and the like may be performed subsequently.
