However, the present utility model is not limited to the embodiments disclosed below, but may be embodied in various different forms, which are provided only for the purpose of completing the disclosure of the present utility model and fully understanding the scope of the present utility model by those skilled in the art, and the present utility model is limited only by the scope of the claims. Like reference numerals denote like constituent elements throughout the specification.

Hereinafter, the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 2 to 4, a display panel laminator is provided for performing a lamination process on a display panel 100. The display panel 100 includes a glass substrate and electronic elements such as diodes, thin film transistors, electrodes, and the like formed on the glass substrate. The protective film 200 is attached to the display panel 100 to protect various electronic components on the glass substrate. The protective film 200 includes a base film 220 and two carriers 210. The two carriers 210 are respectively attached to the opposite first and second sides of the base film 220, and the carriers 210 play a role in supporting and protecting the base film 220 so as to facilitate transportation, storage and use of the entire protective film 200. In the film attaching process, the carrier 210 on the first side of the base film 220 is torn off, the first side of the base film 220 has adhesiveness, and then the first side of the base film 220 is attached to the display panel 100, so that the base film 220 is attached to the display panel 100. Finally, the carrier 210 on the second side of the base film 220 is torn off, and only the base film 220 remains in the protective film 200 to be bonded with the display panel 100 to form a final display product. In this embodiment, the film pasting process of the display panel 100 by the display panel film pasting machine includes two steps, wherein the first step is to bond the base film 220 and the display panel 100, which is also called film pasting; step two is to tear the carrier 210 on the second side of the base film 220, also referred to as a tear film.

The display panel film sticking machine comprises a first adsorption component 1, a second adsorption component 2 and a driving component 3. The first adsorption component 1 is used for adsorbing the display panel 100, the second adsorption component 2 is used for adsorbing the protective film 200, and the driving component 3 is used for driving the first adsorption component 1 and the second adsorption component 2 to be close to or far away from each other so as to enable the limiting panel 100 to be abutted against or separated from the protective film 200, and further achieve adhesion fixation between the protective film 200 and the display panel 100. It should be noted that the carrier 210 on the first side of the base film 220 has been removed by the protective film 200 adsorbed by the second adsorption assembly 2, and the protective film 200 includes the base film 220 and the carrier 210 attached to the second side of the base film 220.

The first suction assembly 1 includes a first substrate 11 and a plurality of first suction cups 12. The plurality of first suckers 12 are distributed on the bottom surface of the first substrate 11 at intervals, and the first suckers 12 are vacuum suckers and are adsorbed on the surface of the display panel 100. The first substrate 11 has a relief area 111 facing the line area of the display panel 100. The first suction cups 12 are located outside the avoidance area 111, and the plurality of first suction cups 12 encircle the periphery of the avoidance area 111.

The second adsorption assembly 2 is disposed below the first adsorption assembly 1 at intervals, and the second adsorption assembly 2 includes a second substrate 21 and a plurality of second suckers 22. The plurality of second suction cups 22 are disposed at intervals on the top surface of the second substrate 21. The second chuck 22 is a vacuum chuck for sucking on a side of the carrier 210 facing away from the base film 220. In this state, the base film 220 is located above the carrier 210. The second substrate 21 is disposed parallel to and spaced apart from the first substrate 11 in the vertical direction, and the second substrate 21 is located below the first substrate 11. This structure makes the display panel 100 directly face the protective film 200 in the vertical direction.

The driving component 3 is used for driving the first adsorption component 1 and the second adsorption component 2 to be close to or far away from each other. The driving components 3 may be one, and one driving component 3 is connected with the first adsorption component 1 or the second adsorption component 2 so as to drive the two adsorption components to be close to or far away from each other. The number of the driving components 3 can be two, and the two driving components 3 are respectively connected with the first adsorption component 1 and the second adsorption component 2 so as to drive the two adsorption components to be close to or far away from each other. In this embodiment, for simplifying the apparatus structure and saving space, the driving unit 3 is provided as one, and the driving unit 3 is connected to the first suction unit 1 located above. The driving assembly 3 drives the first adsorption assembly 1 to move in a vertical direction (illustrated Z direction) so as to move the first adsorption assembly 1 toward or away from the second adsorption assembly 2. When the first adsorption assembly 1 approaches the second adsorption assembly 2, the display panel 100 is abutted against and adhered to the base film 220. When the first adsorption member 1 is away from the second adsorption member 2, the display panel 100 moves upward. The adhesiveness between the base film 220 and the carrier 210 is weaker than the adhesiveness between the base film 220 and the display panel 100, so that the base film 220 moves upward along with the display panel 100, and the base film 220 is separated from the carrier 210, i.e. the carrier 210 on the second side of the base film 220 is torn off, so as to complete the film tearing of the display panel 100.

It can be understood that, the first adsorption component 1 and the second adsorption component 2 are close to or far away from each other along the vertical direction, and when the first adsorption component 1 and the second adsorption component are close to each other, the base film 220 and the display panel 100 can be bonded, namely, the film pasting of the display panel 100 is completed; separation between the base film 220 and the carrier 210 can be achieved when the base film and the carrier are far away, namely, film tearing of the display panel 100 is completed. The mode enables the display panel 100 to finish film pasting and film tearing at the same station, reduces midway transportation, and is beneficial to simplifying the process flow. The first substrate 11 is provided with a plurality of first suction cups 12 for sucking the display panel 100, and the second substrate 21 is provided with a plurality of second suction cups 22 for sucking the protective film 200. When the film is torn, the pulling force between the base film 220 and the carrier 210 is in the same direction as the adsorption force of the first sucker 12 and the second sucker 22. The structure enables the first adsorption assembly 1 to firmly adsorb the display panel 100, and the second adsorption assembly 2 to firmly adsorb the carrier 210 of the protective film 200, so that the carrier 210 can be prevented from falling off, and the working efficiency of the whole film pasting process is further ensured. Meanwhile, by installing the first suction cup 12 at the periphery of the avoidance area 111, the first suction cup 12 can be prevented from applying pressure to the circuit area on the display panel 100, and further, the circuit area is prevented from being pressed by the first suction cup 12 to generate an indentation. The plurality of first suckers 12 encircle the periphery of the avoidance area 111, so that the pressure around the circuit area is balanced, so that the circuit area in the display panel 100 can be tightly attached to the base film 220, and the production quality of the display panel 100 is further ensured.

Optionally, the first suction cup 12 is detachably connected to the first substrate 11, and a distance between the first suction cup 12 and the avoidance area 111 is adjustable. In practical applications, the size of the line area on the display panel 100 is different for different display panels 100. By adjusting the relative position of the first suction cup 12 on the first substrate 11, so as to avoid the circuit area in the display panel 100, the damage of the first suction cup 12 to the electronic components in the circuit area is avoided, and the production quality of the display panel 100 is further ensured.

In an alternative embodiment, referring to fig. 4 and 5, the display panel 100 has a plurality of circuit areas thereon. After the display panel 100 is manufactured, the display panel 100 is cut, a portion in the circuit area forms a final display product, and a portion outside the circuit area is waste. Correspondingly, the first substrate 11 has a plurality of avoidance areas 111, and the plurality of avoidance areas 111 are in one-to-one correspondence with a plurality of line areas in the display panel 100. The plurality of avoidance areas 111 are spaced apart. The first suction cups 12 are distributed between the avoidance areas 111 and the edges of the first substrate 11, and within the gaps between adjacent avoidance areas 111. It should be noted that, when the distance between two adjacent avoidance areas 111 is smaller, a first suction cup 12 may be disposed between two adjacent avoidance areas 111. For example, two avoidance areas 111 on the first substrate 11 are a first avoidance area 115 and a second avoidance area 116, respectively. Along the width direction (Y direction in the drawing) of the first substrate 11, one first suction cup 12 is provided between the first avoidance region 115 and the second avoidance region 116. The first suction cup 12 may be understood to be located around either the first avoidance region 115 or the second avoidance region 116.

The first substrate 11 has a housing chamber 110 therein, and a main gas pipe 4 and a plurality of bronchi 5 for transporting gas are provided in the housing chamber 110. The number of bronchi 5 is the same as that of the first suckers 12, and the bronchi 5 and the first suckers are arranged in a one-to-one correspondence. I.e. each first suction cup 12 communicates with the main air duct 4 via the bronchi 5. A long hole 112 is formed in the bottom surface of the first substrate 11, and the long hole 112 communicates with the accommodation chamber 110. The elongated hole 112 is a waist-shaped hole for mounting the first suction cup 12. One end of the long hole 112 in the longitudinal direction is close to the escape area 111, and the other end extends in a direction away from the escape area 111. The first suction cup 12 is mounted in the long hole 112 and is movable in the length direction of the long hole 112, so that the first suction cup 12 can be close to the avoidance area 111 or far from the avoidance area 111. It is understood that the size of the line area varies from display panel 100 to display panel. In practical applications, the position of the first suction cup 12 can be adjusted according to the actual size of the display area on the display panel 100, so that the first suction cup 12 does not cause an indentation on the circuit area, and meanwhile, the first suction cup 12 can be made to be as close to the circuit area as possible, so as to ensure that the circuit area is tightly attached to the base film 220.

Specifically, the first suction cup 12 includes a support rod 121, a suction head 122, and a stopper plate 123. One end of the support rod 121 passes through the long hole 112 and extends into the accommodating cavity 110, and the limiting plate 123 is arranged at one end of the support rod 121 in the accommodating cavity 110, and the size of the limiting plate 123 is larger than that of the long hole 112, so that the limiting plate 123 abuts against the surrounding area of the long hole 112. The support rod 121 is provided with external threads, the support rod 121 is connected with a nut 124 in a threaded manner, and the nut 124 is positioned at one end of the long hole 112, which is away from the limiting plate 123. The nut 124 serves as a fastener for fixing the first suction cup 12 to achieve the mounting fixation of the first suction cup 12 with the long hole 112. When the first suction cup 12 needs to be adjusted, the first suction cup 12 can be moved along the length direction of the long hole 112 by loosening the nut 124. The suction head 122 is arranged at one end of the support rod 121, which is away from the limiting plate 123, an air passage communicated with the suction head 122 is arranged in the support rod 121, and one end of the air passage is connected with the bronchus 5.

Specifically, the first adsorption assembly 1 further includes an air pump, which is in communication with the main air pipe 4. The air pump is used for driving air to flow along the main air pipe 4 and the bronchi 5 so as to realize the air suction and inflation of the first sucker 12, so that the first sucker 12 can suck or loosen the display panel 100.

In practical application, the display panel 100 has a plurality of circuit areas, and when one of the circuit areas is rejected due to quality problems, the rejected circuit area is not required to be subjected to film pasting treatment. Correspondingly, in the protective film 200, a plurality of base films 220 are provided, and a plurality of base films 220 are provided corresponding to a plurality of wiring regions, respectively. The carrier 210 on its first side need not be peeled off of the base film 220 corresponding to the rejected line area. When the display panel 100 is abutted against the protective film 200, the scrapped circuit region is not bonded to the base film 220 in the corresponding region. When the display panel 100 is separated from the carrier 210 after being attached, that is, when the display panel 100 is torn, the carrier 210 on the first side of the base film 220 corresponding to the scrapped line area is detached. By using the first adsorption assembly 1 to adsorb the display panel 100 and the second adsorption assembly 2 to adsorb the protective film 200, the display panel 100 is located above the protective film 200, so that the carrier 210 falling off can be prevented from falling onto the display panel 100 when the first adsorption assembly 1 and the second adsorption assembly 2 are far away from each other. And further, the carrier 210 that is dropped is prevented from being transported to the next process along with the display panel 100, so as to influence the smooth proceeding of the production flow of the display panel 100.

In an alternative embodiment, referring to fig. 6 and 7, a plurality of hole sets for mounting the first suction cup 12 are provided on the first substrate 11, and the plurality of hole sets are wound around the avoidance area 111. Each hole group comprises a plurality of mounting holes 113 which are distributed at intervals, the mounting holes 113 are threaded holes, the distance between each mounting hole 113 in each hole group and the avoidance area 111 is different, namely the linear distance between the mounting hole 113 and the corresponding avoidance area 111 is different. The first suction cup 12 is provided with external threads matched with the mounting holes 113, and one of the plurality of mounting holes 113 in the hole group is connected with the first suction cup 12 in a threaded mode. In practical application, by connecting the first suction cup 12 with different mounting holes 113, the position of the first suction cup 12 can be adjusted according to the actual size of the display area on the display panel 100, so that the first suction cup 12 cannot cause indentation on the circuit area, and meanwhile, the first suction cup 12 can be made to be as close to the circuit area as possible, so as to ensure that the circuit area is tightly attached to the base film 220.

Specifically, the first substrate 11 has a receiving cavity 110 therein, the mounting holes 113 are formed in the bottom surface of the first substrate 11, and all the mounting holes 113 are communicated with the receiving cavity 110. The first suction cup 12 is threadedly coupled to one of the mounting holes 113 in the set of holes and communicates the first suction cup 12 with the corresponding mounting hole 113. The first adsorption assembly 1 further comprises an air pump and a hole plug 114. The air pump is communicated with the accommodating chamber 110 through a pipe so that the air pump can suck air or inflate the accommodating chamber 110. The rest of the mounting holes 113 in the hole group, to which the first suction cup 12 is not mounted, are provided with hole plugs 114, and the hole plugs 114 are used for plugging the mounting holes 113. The accommodating chamber 110 is pumped and inflated by the air pump so that the first suction cup 12 can suck or release the display panel 100.

In an alternative embodiment, referring to fig. 6, one of the hole groups includes two mounting holes 113, where one mounting hole 113 is spaced apart from the avoidance area 111 by L1, and the other mounting hole 113 is spaced apart from the avoidance area 111 by L2, where L2 > L1.

Alternatively, referring to fig. 8, the first suction cup 12 includes a support rod 121 and a suction head 122, one end of the support rod 121 is connected to the first substrate 11, and the suction head 122 is disposed at an end of the support rod 121 facing away from the first substrate 11. The suction head 122 has a hollow bowl-shaped structure, a chamber for containing gas is formed in the suction head 122, and the chamber of the suction head 122 is communicated with the air passage in the support rod 121. Along the axial direction of the cleaner head 122, the sidewall of the cleaner head 122 is curved to form a curved portion 1221 extending toward the center (i.e., axis) of the chamber. When the film is attached, the first adsorption assembly 1 applies a certain pressure to the display panel 100. The curved portion 1221 is capable of undergoing elastic deformation when the cleaner head 122 is subjected to an axial compressive force (i.e., downward pressure). The structure enables the suction head 122 to be elastically connected with the display panel 100, so that the display panel 100 is prevented from being subjected to excessive pressure to generate indentation.

Optionally, a plurality of second suction cups 22 are distributed on the second substrate 21. The carrier 210 at the second side of the base film 220 has a greater structural thickness and structural strength than the carrier 210 at the first side of the base film 220 to maintain the flatness of the entire base film 220. The second suction cup 22 does not cause an indentation to the display panel 100 under the blocking effect of the protective film 200. Therefore, the plurality of second suction cups 22 are distributed on the second substrate 21 in an array, and the structure can form uniform support for each region of the protective film 200 to ensure the overall flatness of the protective film 200. The structure of the second suction cup 22 can be designed with reference to the first suction cup 12, and will not be described here.

Alternatively, as shown with reference to fig. 3, the driving assembly 3 includes a third base plate 31, a driving part 32, and a guide 33.

The driving part 32 may be a cylinder or an electric telescopic member, the fixed end of the driving part 32 is mounted on the third substrate 31, the telescopic end of the driving part 32 is connected with the first substrate 11, and the first substrate 11 and the third substrate 31 are driven to be close to or far away from each other through telescopic movement of the driving part 32. When the first substrate 11 approaches the third substrate 31, the first substrate 11 is away from the second substrate 21; when the first substrate 11 is away from the third substrate 31, the first substrate 11 approaches the second substrate 21. The driving parts 32 are plural, the driving parts 32 move synchronously, and the driving parts 32 are uniformly distributed on the third substrate 31.

The plurality of guides 33 are provided, and the guides 33 are provided at least at four corners of the third substrate 31. Of course, in other embodiments, the guide member 33 may be fixedly connected to the first substrate 11, and the guide member 33 may be slidably connected to the third substrate 31.

Optionally, the display panel film sticking machine further includes a conveying device, the conveying device includes a guide rail and a driving motor, the third substrate 31 is slidably connected with the guide rail, the driving motor is installed on the third substrate 31, and the driving motor is in transmission connection with the guide rail, so that the driving motor can drive the third substrate 31 to move along the length direction of the guide rail. In this embodiment, the conveying device is used for conveying the third substrate 31 along the horizontal direction, so that the driving assembly 3 and the first adsorption assembly 1 can synchronously move along the horizontal direction, and the display panel 100 after the film pasting treatment is conveyed to another station.

The technical effects of this embodiment are: by arranging the first adsorption component 1 and the second adsorption component 2 to be close to or far away from each other in the vertical direction, the base film 220 and the display panel 100 can be bonded when the first adsorption component and the second adsorption component are close to each other, namely the film pasting of the display panel 100 is completed; separation between the base film 220 and the carrier 210 can be achieved when the base film and the carrier are far away, namely, film tearing of the display panel 100 is completed. The mode enables the display panel 100 to finish film pasting and film tearing at the same station, reduces midway transportation, and is beneficial to simplifying the process flow. The first substrate 11 is provided with a plurality of first suction cups 12 for sucking the display panel 100, and the second substrate 21 is provided with a plurality of second suction cups 22 for sucking the protective film 200. When the film is torn, the pulling force between the base film 220 and the carrier 210 is in the same direction as the adsorption force of the first sucker 12 and the second sucker 22. The structure enables the first adsorption assembly 1 to firmly adsorb the display panel 100, and the second adsorption assembly 2 to firmly adsorb the carrier 210 of the protective film 200, so that the carrier 210 can be prevented from falling off, and the working efficiency of the whole film pasting process is further ensured. Meanwhile, by installing the first suction cup 12 at the periphery of the avoidance area 111, the first suction cup 12 can be prevented from applying pressure to the circuit area on the display panel 100, and further, the circuit area is prevented from being pressed by the first suction cup 12 to generate an indentation. The plurality of first suckers 12 encircle the periphery of the avoidance area 111, so that the pressure around the circuit area is balanced, so that the circuit area in the display panel 100 can be tightly attached to the base film 220, and the production quality of the display panel 100 is further ensured.
