The present invention provides a film sticking module 100, as shown in fig. 5 to 7, the film sticking module 100 is used for sticking a film 501 to a workpiece 502. Referring to fig. 1, the lamination module 100 includes a first suction head 105, a lamination member 106, and a driving mechanism 103.
The first suction head 105 can adsorb the film 501. For example, referring to fig. 4, the first suction head 105 has a plurality of first suction holes 402 for air to pass through, the first suction head 105 is connected to a vacuum pump through a hose (neither the vacuum pump nor the hose is shown), after the vacuum pump is started, a negative pressure is generated at the first suction holes 402, and if the membrane 501 is located near the first suction holes 402, the membrane 501 is sucked by the first suction head 105. Referring to fig. 6, the first suction head 105 can also press the film 501 against the workpiece 502. Referring to fig. 5-7, after the first tip 105 adsorbs the film 501, the first tip 105 and the workpiece 502 may be brought together until the first tip 105 affixes the film 501 to the workpiece 502. Referring to fig. 6, when the first suction head 105 attaches the film 501 to the workpiece 502, the film 501 is held between the first suction head 105 and the workpiece 502, and one side of the film 501 is in contact with the first suction head 105 and the other side is attached to the workpiece 502.
Referring to fig. 4, the squeeze film member 106 is disposed at a side of the first suction head 105, and the squeeze film member 106 is disposed adjacent to the first suction head 105, the squeeze film member 106 serving to press the film 501 against the workpiece 502. The number of the pressing members 106 may be only one, or two; referring to fig. 4, in case that the squeeze films 106 are provided in two, the two squeeze films 106 may be distributed at both sides of the first suction head 105. Specifically, referring to fig. 6 and 7, after the first suction head 105 attaches a portion of the film 501 to the workpiece 502, the portion of the film 501 that is not attached to the workpiece 502 may be pressed against the surface of the workpiece 502 by the squeeze film member 106. The pressing member 106 may be provided as a roller to reduce damage to the film 501 and to improve the applicability of the pressing member 106 to the workpiece 502 having a curved surface. While the die member 106 may be considered in other embodiments as a plate or block member for pressing the die against the workpiece 502.
The driving mechanism 103 is connected to at least one of the film pressing member 106 and the first suction head 105, and the driving mechanism 103 is used for driving the film pressing member 106 to move relative to the first suction head 105, so as to change the protruding distance of the film pressing member 106 relative to the first suction head 105. The distance between the film pressing member 106 and the surface of the first suction head 105 on the side where the first suction holes 402 are provided is "the projecting distance of the film pressing member 106 with respect to the first suction head 105" with reference to the orientation of the first suction holes 402 of the first suction head 105. For example, referring to fig. 4, the first suction holes 402 are disposed downward, the first suction holes 402 are located at the lower side of the first suction head 105, and accordingly, in a top-down direction with reference to fig. 7, a distance between the lower side of the first suction head 105 and the die pressing member 106 (the lower end of the die pressing member 106) is "a protruding distance of the die pressing member 106 with respect to the first suction head 105". In the state shown in fig. 7, the squeeze film member 106 protrudes by a distance L with respect to the first suction head 105.
Referring to fig. 5 to 7 in sequence, the protruding distance of the film pressing member 106 with respect to the first suction head 105 may gradually increase under the driving of the driving mechanism 103; in this process, the film pressing member 106 gradually presses the portion of the film 501 not contacted by the first suction head 105 against the workpiece 502 (at this time, the first suction head 105 still presses the film 501 against the workpiece 502), thereby gradually attaching the entire sheet of film 501 to the workpiece 502. For example, referring to fig. 7, the first suction head 105 may apply a portion of the film 501 to the top of the workpiece 502 and the lamination film 106 may apply another portion of the film 501 to the side of the workpiece 502. In the above process, the pressing of the film 501 by the gradually moving squeeze film 106 can reduce the wrinkles of the film 501; in addition, the film pressing member 106 can gradually press air between the film 501 and the workpiece 502, so that bubbles generated after film pasting are reduced. Some embodiments of the driving mechanism 103 will be described in detail below, but the driving mechanism 103 is not limited to the structure described in the present invention as long as the driving mechanism 103 can change the protruding distance of the pressure membrane 106 with respect to the first suction head 105.
In the film laminating module 100, the first suction head 105 can suck the film 501 and can adhere one part of the film 501 to the workpiece 502, and the film laminating piece 106 can adhere the other part of the film 501 to the workpiece 502 and can press the film 501, so that wrinkles of the film 501 and bubbles after laminating are reduced. That is, the lamination module 100 of the present invention has three functions of film suction, lamination, and lamination.
Furthermore, since the film pressing member 106 is disposed adjacent to the first suction head 105, after the first suction head 105 has attached the film 501 to the workpiece 502, the driving mechanism 103 can attach another part of the film 501 to the workpiece 502 by gradually projecting the film pressing member 106 with respect to the first suction head 105, while the first suction head 105 is still pressing the film 501 against the workpiece 502. In the film pasting process of the workpiece 502, the workpiece 502 does not need to be transferred in a large range between the two steps of film pasting and film pressing, and a part for film pasting and a part for film pressing do not need to move in a large range and are transferred to the workpiece 502 in sequence; therefore, the interval time between the lamination and the squeeze film is shortened, which is advantageous to improve the overall lamination efficiency of the lamination module 100.
In addition, the lamination module 100 of the present invention is advantageous in reducing the volume of the lamination apparatus 800 because it is not necessary to reserve a large movement space for the first suction head 105 and the lamination member 106.
Referring to fig. 4, in some embodiments, the film sticking module 100 further comprises a second suction head 107, and the second suction head 107 is also capable of sucking the film 501. Referring to FIG. 4, the first suction head 105 and the second suction head 107 are oriented in the same direction, the second suction head 107 is disposed at a side of the first suction head 105, and the second suction head 107 is spaced apart from the first suction head 105; the film pressing member 106 is disposed between the first suction head 105 and the second suction head 107, and the driving mechanism 103 can also drive the second suction head 107 and the film pressing member 106 to move together. Referring to FIG. 4, the second suction head 107 may have a second suction hole 403 through which air passes, and the second suction head 107 may be connected to a vacuum pump, which generates a negative pressure at the second suction hole 403 so that the second suction head 107 sucks the membrane 501. The second suction head 107 and the first suction head 105 are oriented in the same direction, specifically, the first suction hole 402 and the second suction hole 403 are oriented in the same direction (the first suction hole 402 and the second suction hole 403 are both downward in FIG. 4).
On one hand, the second suction head 107 can increase the adsorption area of the film 501 to the film sticking module 100, and improve the stability of the film suction; on the other hand, since the second suction head 107 moves together with the film pressing member 106, it is advantageous to keep the film 501 tensioned during the film pressing process of the film pressing member 106, thereby advantageously reducing wrinkles and air bubbles after the film is attached.
If the film pressing member 106 is provided with only one, the number of the second suction heads 107 may be set to one, and the second suction heads 107 and the film pressing member 106 are provided on the same side of the first suction head 105. Referring to fig. 4, if the film pressing member 106 is provided in two, the number of the second suction heads 107 may be two, and the two second suction heads 107 are respectively spaced apart from each other on both sides of the first suction head 105.
To enable the lamination module 100 to be adapted to workpieces 502 with complex shapes (e.g., workpieces 502 having curved surfaces), in some embodiments, the two lamination members 106 are also capable of lateral movement relative to the lamination members 106. Referring to fig. 3, the lamination module 100 further includes a fixing plate 104, the first suction head 105 is mounted on the fixing plate 104, and the lamination member 106 is slidably coupled to the fixing plate 104. Specifically, the fixing plate 104 may have a slide rail (the slide rail is located on the lower side of the fixing plate 104, and is not shown in fig. 4), the film laminating module 100 further includes a slide block 306, the film pressing member 106 is connected to the slide block 306, and the slide block 306 is mounted on the slide rail. The sliding direction of the film pressing member 106 relative to the fixing plate 104 is perpendicular to the moving direction of the film pressing member 106 under the driving mechanism 103. For example, referring to fig. 3 and 7, the pressing member 106 can slide left and right relative to the fixing plate 104, and the driving mechanism 103 can drive the pressing member 106 to move up and down. Referring to fig. 3, the lamination module 100 further includes a reset member 305, and the reset member 305 can be used to drive the two lamination members 106 to be close to each other (refer to close in the sliding direction of the lamination members 106).
Referring to fig. 6 and 7, the surfaces of some workpieces 502 have curved surfaces, and the widths of the workpieces 502 gradually increase from top to bottom. The first suction head 105 can press the film 501 on top of the curved surface, and during the process that the protruding distance of the lamination member 106 relative to the first suction head 105 gradually increases, the distance between the two lamination members 106 also gradually increases, so that the position of the lamination member 106 is adapted to the curved surface of the workpiece 502. Since the reset piece 305 can drive the two film pressing pieces 106 to close, the closing tendency enables the film pressing pieces 106 to press the film 501 against the side of the workpiece 502 even if the width of the workpiece 502 changes.
The reset member 305 may have a different configuration. In some embodiments, the reset piece 305 may be resilient; that is, the restoring member 305 is provided as an elastic member, and more specifically, the restoring member 305 may be provided as a tension spring (as shown in fig. 3). For example, referring to fig. 3, in the case that one pressure film member 106 is disposed on each of both sides of the first suction head 105, both ends of the reset member 305 may be connected to the two pressure film members 106, respectively, and the elastic force of the reset member 305 is used to drive the two pressure film members 106 to approach each other. Still alternatively, two restoring elements 305 may be provided, one end of the restoring element 305 is connected to the diaphragm 106, and the other end of the restoring element 305 is connected to the central position of the fixing plate 104.
In other embodiments, it is also contemplated that the two pressing members 106 will be brought together by magnetic force, i.e., the restoring member 305 is provided as a magnet. Each of the pressing film members 106 is connected to a reset member 305, and the attraction between the two reset members 305 is used to drive the two pressing film members 106 to move close to each other.
In order to adapt the film sticking module 100 to the workpiece 502 having a curved surface, the film sticking module 100 may also have the following arrangement. The first suction head 105 has a holding surface 401 for holding the film 501 and pressing the film 501 to the surface of the workpiece 502, the first suction holes 402 may be disposed on the holding surface 401, the holding surface 401 may be disposed as a curved surface, and the holding surface 401 is recessed. Referring to fig. 5, in the arrangement direction between the film pressing members 106 and the first suction head 105, or in the arrangement direction of the two film pressing members 106 (both correspond to the left-right direction): the center of the abutting surface 401 is recessed in a direction away from the workpiece 502 with respect to the two ends thereof.
The arrangement of the driving mechanism 103 will be described below.
Referring to fig. 3, the driving mechanism 103 includes a fixing plate 104, a first driving assembly 101, and a second driving assembly 102. The film pressing member 106 is mounted on the fixing plate 104, the first driving assembly 101 is connected to the fixing plate 104, and the first driving assembly 101 can drive the fixing plate 104 to move together. The second driving assembly 102 is mounted to the fixing plate 104, the first suction head 105 is connected to the second driving assembly 102, and the second driving assembly 102 is used for driving the first suction head 105 to move relative to the fixing plate 104. If the lamination module 100 further comprises a second suction head 107, the second suction head 107 may also be mounted on the mounting plate 104.
The moving direction of the fixing plate 104 driven by the first driving assembly 101 and the moving direction of the first suction head 105 driven by the second driving assembly 102 are parallel to each other.
