Description

Technical Field

[0001] This application relates to the field of workpiece production, and particularly to a film laminating device. Background Art

[0002] During the production process of some products, film laminating is required. In the related art, film laminating is usually carried out manually or simply pressed by a machine. The film laminating accuracy of this method is low, and it cannot be effectively attached to the surface of the workpiece. Summary of the Invention

[0003] In view of this, it is necessary to provide a film laminating device that can improve the laminating accuracy.

[0004] An embodiment of this application provides a film laminating device, including a frame. The film laminating device further includes a limiting mechanism and a functional mechanism. The limiting mechanism is arranged on the frame and is configured to position a first workpiece and make at least a part of the first workpiece and a second workpiece arranged on the first workpiece extend out of the limiting mechanism. The functional mechanism includes a bending component and a driving member connected to each other. The driving member can drive the bending component to move. The bending component includes a roller, and the roller is configured to rotatably press against the second workpiece so that the part of the second workpiece extending out of the first workpiece adheres to the first workpiece. The extending direction of the rotation axis of the roller forms an angle greater than 0° with the extending direction of the first workpiece extending out of the limiting mechanism.

[0005] In the film laminating device of the above embodiment, the limiting mechanism can limit the positions of the first workpiece and the second workpiece. The roller is driven to move by the driving member so that the roller rolls to bend the second workpiece. The rotation axis of the roller extends in the horizontal direction and intersects with the extending direction of the first workpiece, so that the roller can apply an inclined component force to the second workpiece, enabling the second workpiece to completely adhere to the arc surface, improving the yield rate, and reducing the situation where there is a gap between the second workpiece and the first workpiece when the second workpiece adheres to the first workpiece, and can improve the laminating accuracy.

[0006] In at least one embodiment, the functional mechanism further includes a film tearing component. The film tearing component is connected to the driving member and is located on one side of the bending component. The film tearing component is used to tear the protective film that is at least partially separated from the second workpiece when the second workpiece adheres to the first workpiece.

[0007] In the film laminating device of the above embodiment, when the roller bends the second workpiece, the protective film also bends with the second workpiece. When the pressing of the roller is released, the second workpiece bends and adheres to the first workpiece, the elastic deformation of the protective film is restored, and it separates from the second workpiece. The driving member can drive the film tearing assembly to move to the position of the protective film and clamp the protective film. Subsequently, under the action of the driving member, the film tearing assembly tears the protective film from the second workpiece. The protective film can be separated from the second workpiece due to the restoration of its elastic deformation, and the film tearing process is simple and convenient.

[0008] In at least one embodiment, the film laminating device further includes a material transfer mechanism. The material transfer mechanism is arranged on the frame. The material transfer mechanism includes a fixture. The fixture is provided with a placement groove. The placement groove has a guiding portion and a placement portion that are communicated with each other. The guiding portion is used to guide the first workpiece and the second workpiece. The placement portion cooperates with the first workpiece and the second workpiece. The functional mechanism further includes a material picking component. The material picking component is connected to the driving member and is located on one side of the bending component. The material picking component is used to reciprocally transport the first workpiece and the second workpiece between the material transfer mechanism and the limiting mechanism.

[0009] In the film laminating device of the above embodiment, when the first workpiece or the first workpiece and the second workpiece are placed in the placement groove, the first workpiece or the first workpiece and the second workpiece first pass through the guiding portion. Since the size of the guiding portion is large, even if there is an error in the position of the first workpiece or the first workpiece and the second workpiece, they can be placed in the guiding portion. The first workpiece located in the guiding portion can be located in the placement portion under the guidance of the guiding portion to accurately position the workpiece.

[0010] In at least one embodiment, the film laminating device further includes a coil feeding mechanism and an attaching mechanism. The coil feeding mechanism is arranged on the frame and is adjacent to the material transfer mechanism for transporting the second workpiece. The attaching mechanism is arranged on the mechanism for adsorbing the second workpiece of the coil feeding mechanism and attaching it to the first workpiece in the placement groove.

[0011] In the film laminating device of the above embodiment, the coil feeding mechanism transports the second workpiece, and the adsorption mechanism adsorbs and transports the second workpiece on the coil feeding mechanism to the first workpiece in the placement groove so that the second workpiece adheres to the first workpiece.

[0012] In at least one embodiment, the film laminating device further includes a vision positioning mechanism, which includes a fixed camera assembly and a movable camera assembly. The fixed camera assembly is disposed on the frame and is located on one side of the coil feeding mechanism. The fixed camera assembly is configured to acquire an image of the second workpiece when the attaching mechanism sucks the second workpiece and is at the camera position, and adjust the position of the second workpiece by comparing the image of the second workpiece with a preset second workpiece image. The movable camera assembly is connected to the attaching mechanism and is configured to acquire an image of the first workpiece when the first workpiece is in the placement groove, and adjust the position of the second workpiece on the attaching mechanism by comparing the image of the first workpiece with a preset first workpiece image, so that the position of the second workpiece corresponds to that of the first workpiece.

[0013] In the film laminating device of the above embodiment, by comparing the image of the first workpiece with the preset first workpiece image, the position error of the first workpiece of the attaching head at this time is confirmed, and according to this error, the position of the attaching head is correspondingly adjusted through the first transfer unit, the second transfer unit and the rotating member, so as to adjust the position of the second workpiece, so as to offset the position error of the first workpiece, so that the second workpiece can be accurately attached to the first workpiece. By sequentially confirming the positions of the second workpiece and the first workpiece to perform two position corrections on the second workpiece, the position accuracy of the second workpiece attached to the first workpiece can be effectively improved, so as to improve the yield.

[0014] In at least one embodiment, the attaching mechanism includes an attaching component and a transfer component. The attaching component includes an attaching head and a rotating member. The attaching head is connected to the rotating member, and the rotating member can drive the attaching head to rotate. The attaching head is used for adsorbing the second workpiece and attaching it to the first workpiece. The transfer component is disposed on the frame and is connected to the rotating member, and is configured to drive the attaching head to adsorb the second workpiece and attach the second workpiece to the first workpiece.

[0015] In the film laminating device of the above embodiment, since the sizes of the first workpiece and the second workpiece are small and the required attaching position accuracy is high, driving the attaching head to rotate by the rotating member can further improve the attaching accuracy of the second workpiece attached to the first workpiece, so as to improve the product yield.

[0016] In at least one embodiment, the film laminating device further includes a pressing mechanism, which includes a pressing member and a telescopic member. The pressing member includes a connecting plate, a pressing block and an elastic member. One end of the elastic member is connected to the connecting plate, and the other end is connected to the pressing block. The pressing block is used for pressing the first workpiece and the second workpiece in the placement groove. The telescopic member is disposed on the frame and is connected to the connecting plate, and the telescopic member can drive the pressing member to move vertically.

[0017] In the film pasting device of the above embodiment, when the pressing block 912 presses against the first workpiece 200 and the second workpiece 300, the elastic member 913 is compressed so that the pressing block 912 can more stably press against the first workpiece 200 and the second workpiece 300, improving the pressing effect.

[0018] In at least one embodiment, the film pasting device further includes a tray and a handling mechanism. The tray is provided with a receiving groove for placing the first workpiece and / or the second workpiece. The handling mechanism and the functional mechanism are located at opposite ends of the material transfer mechanism. The handling mechanism includes a tray handling member, a workpiece handling member, and a power member. The tray handling member is used to handle the tray. The workpiece handling member is located on one side of the tray handling member and is used to transfer the first workpiece in the receiving groove to the placement groove, or transfer the first workpiece and the second workpiece in the placement groove to the receiving groove. The power member is connected to the tray handling member and the workpiece handling member to drive the tray handling member or the workpiece handling member to move.

[0019] In the film pasting device of the above embodiment, the handling mechanism can both handle the tray and the first workpiece or the first workpiece and the second workpiece. The handling mechanism has three handling functions, which can improve the utilization rate of the handling mechanism and save costs.

[0020] In at least one embodiment, the receiving groove of the tray is formed by thermoforming. The film pasting device further includes a positioning frame. The positioning frame is located at one end of the material transfer mechanism. The positioning frame includes a bracket and a positioning member provided on the bracket. The structure of the positioning member is the same as that of the tray.

[0021] In the film pasting device of the above embodiment, the structure of the positioning member is the same as that of the tray to reduce the types of parts, facilitate maintenance or replacement, and since there are multiple receiving grooves on the tray, there are multiple positions for positioning between the positioning member and the tray, and the positioning accuracy of the tray is high.

[0022] In at least one embodiment, the film pasting device further includes a transportation mechanism. The transportation mechanism includes a transportation component and a lifting component. The transportation component is located on one side of the handling mechanism. The transportation component includes a transportation main body, a transportation belt, and a support plate. The transportation belt is wound around the transportation main body. The tray can be placed on the transportation belt and at least part of it protrudes out of the transportation belt. The support plate is provided on the transportation main body and supports the transportation belt. The lifting component is connected to the transportation main body and is used to lift the part of the tray protruding out of the transportation belt to lift the tray, or place the tray of the lifting component on the transportation belt. The tray handling member can transfer the tray on the lifting component to the positioning member.

[0023] In the film laminating device of the above embodiment, the transport mechanism can transport the tray, and the support plate can block the downward bending of the conveyor belt to keep the position of the conveyor belt stable. The lifting component is connected to the transport main body and is used to lift the part of the tray exposed from the conveyor belt to lift the tray, or place the tray of the lifting component on the conveyor belt. The tray is lifted by the lifting component to facilitate the handling mechanism to accurately handle the tray.

[0024] The film laminating device of the present application can attach the second workpiece to the first workpiece. The second workpiece is bent by the roller, and during the process of pressing against the second workpiece, an inclined downward component force can be applied to the second workpiece through the elastic deformation and rolling of the roller, so that the second workpiece is completely attached to the first workpiece. After the second workpiece is bent, the protective film is separated from the second workpiece, and the film tearing component can simply and quickly tear the protective film.

[0086] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0087] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "provided on" another component, it can be directly provided on the other component or there may be an intermediate component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "rear", and similar expressions used herein are only for the purpose of illustration.

[0088] When two elements (planes, lines) are arranged in parallel, it should be understood that the relationship between the two elements includes both parallel and substantially parallel. Among them, substantially parallel should be understood that there may be a certain angle between the two elements, and the angle of the angle is greater than 0° and less than or equal to 10°.

[0089] When two elements (planes, lines) are arranged perpendicular to each other, it should be understood that the relationship between the two elements includes both perpendicular and substantially perpendicular. Among them, substantially perpendicular should be understood that the included angle between the two elements is greater than or equal to 80° and less than 90°.

[0090] When a certain parameter is greater than, equal to, or less than a certain endpoint value, it should be understood that the endpoint value allows a tolerance of ±10%. For example, if A is greater than B by 10, it should be understood to include the case where A is greater than B by 9, and also include the case where A is greater than B by 11.

[0091] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the description of this application herein are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0092] Some embodiments of this application provide a film pasting device, including a frame. The film pasting device further includes a limiting mechanism and a functional mechanism. The limiting mechanism is arranged on the frame and is configured to position a first workpiece, and enable at least a part of the first workpiece and a second workpiece arranged on the first workpiece to extend out of the limiting mechanism. The functional mechanism includes a bending component and a driving component connected to each other. The driving component can drive the bending component to move. The bending component includes a roller, and the roller is configured to rotatably press against the second workpiece, so that the part of the second workpiece extending out of the first workpiece adheres to the first workpiece. The extending direction of the rotation axis of the roller forms an angle greater than 0° with the extending direction of the first workpiece extending out of the limiting mechanism.

[0093] In the film pasting device of the above embodiment, the limiting mechanism can limit the positions of the first workpiece and the second workpiece, and drive the roller to move through the driving component, so that the roller rolls to bend the second workpiece. The rotation axis of the roller extends in the horizontal direction and intersects with the extending direction of the first workpiece, so that the roller can apply an inclined component force to the second workpiece, so that the second workpiece can completely adhere to the arc surface, improving the yield rate and reducing the situation that there is a gap between the second workpiece and the first workpiece when the second workpiece adheres to the first workpiece, and the pasting accuracy can be improved.

[0094] Some embodiments of this application will be described below in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0095] Please refer to Figure 1 and Figure 2 , an embodiment of this application provides a film pasting device 100. The film pasting device 100 is used to paste a second workpiece 300 on a first workpiece 200. The first workpiece 200 is a structure that needs to be pasted with a film, such as a rotating shaft of a flip electronic device, the back of a watch, etc. The flip electronic device includes but is not limited to a laptop computer, a folding mobile phone, etc.

[0096] The second workpiece 300 is a film-like structure, such as a mylar sheet (PET polyester film), a polypropylene film, a polyvinyl chloride film, etc. In addition to plastic films, it can also be a non-plastic film, such as an optical film, a composite film, a superconducting film, a polyester film, a nylon film, etc. Further, a structure that is partially plastically deformable and used to adhere to the first workpiece 200 can also be understood as a film-like structure, such as a metal sheet. In the embodiments of the present application, the second workpiece 300 is introduced as a mylar sheet.

[0097] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the first workpiece 200 includes a first surface 201 and a second surface 202. The first surface 201 is connected to the second surface 202, and the shape of the second surface 202 is arc-shaped. Through the preliminary adhesion of the film laminating device 100, the second workpiece 300 can be adhered to the first surface 201, and a part of the second workpiece 300 protrudes out of the first workpiece 200. Through the second adhesion of the film laminating device 100, the part that originally protruded out of the first workpiece 200 after the preliminary adhesion can be adhered to the second surface 202. Optionally, the shape of the first workpiece 200 is sheet-like, and the shape of the second workpiece 300 is generally E-shaped. A protective film 400 is provided on the second workpiece 300 to reduce the second workpiece 300 from being scratched. It can be understood that the second surface 202 of the first workpiece 200 is not limited to being an arc surface, and it can also be a flat surface. Generally, the difficulty of adhering the second workpiece 300 to an arc surface is higher than that of adhering to a flat surface. In the embodiments of the present application, the second surface 202 is taken as an arc surface for illustration.

[0098] The process of adhering the second workpiece 300 to the first workpiece 200 is as follows: The second workpiece 300 is adhered to the first surface 201 of the first workpiece 200, and a part of the second workpiece 300 extends out of the first workpiece 200. The part of the second workpiece 300 that extends out of the first workpiece 200 is bent, so that the part that originally extended out of the first workpiece 200 of the second workpiece 300 is adhered to the second surface 202 of the first workpiece 200. After the second workpiece 300 is bent, the protective film 400 will not be bent with the second workpiece 300, but elastically deforms and recovers, so that the protective film 400 is separated from the bent part of the second workpiece 300. After the protective film 400 is torn off from the second workpiece 300, the first workpiece 200 and the second workpiece 300 are pressed together to complete the adhesion of the second workpiece 300 to the first workpiece 200. It can be understood that the above process is only one embodiment of the present application, only for the convenience of understanding the present application, and does not represent the entire scope claimed by the present application. The process of adhering the second workpiece 300 to the first workpiece 200 is not limited to the above process. For example, the protective film 400 can be separated from the second workpiece 300 first, and then the second workpiece 300 can be adhered to the first workpiece 200.

[0099] Please refer to in combinationFigure 1 , the film laminating device 100 includes a conveying mechanism 10, a handling mechanism 20, a material transfer mechanism 30, a coil material mechanism 40, an attaching mechanism 50, a vision positioning mechanism 60, a functional mechanism 70, a limiting mechanism 80 and a pressing mechanism 90. The overall working process is as follows:

[0100] The conveying mechanism 10 conveys the first workpiece 200 from the upstream. The handling mechanism 20 transports the first workpiece 200 to the material transfer mechanism 30. The attaching mechanism 50 takes out the second workpiece 300 from the coil material mechanism 40, and respectively positions the second workpiece 300 and the first workpiece 200 through the vision positioning mechanism 60. The attaching mechanism 50 attaches the second workpiece 300 to the first workpiece 200 on the material transfer mechanism 30. The functional mechanism 70 takes out the first workpiece 200 and the second workpiece 300 on the material transfer mechanism 30 and places them on the limiting mechanism 80. The functional mechanism 70 bends the second workpiece 300 so that the second workpiece 300 adheres to the first workpiece 200 and tears off the protective film 400 on the second workpiece 300. The functional mechanism 70 takes the first workpiece 200 and the second workpiece 300 off the limiting mechanism 80 and places them on the material transfer mechanism 30. The material transfer mechanism 30 drives the first workpiece 200 and the second workpiece 300 to move below the pressing mechanism 90, and the pressing mechanism 90 presses the first workpiece 200 and the second workpiece 300 to complete the connection of the second workpiece 300 and the first workpiece 200. The material transfer mechanism 30 drives the first workpiece 200 and the second workpiece 300 to move near the handling mechanism 20, and the handling mechanism 20 transports the first workpiece 200 and the second workpiece 300 to the conveying mechanism 10 and transports them to the downstream through the conveying mechanism 10.

[0101] Please refer to Figure 6 and Figure 7 , the film laminating device 100 further includes a tray 1b. The tray 1b is provided with a plurality of accommodating grooves 10b. The plurality of accommodating grooves 10b are arranged in a rectangular array. The accommodating grooves 10b are used to place the first workpiece 200 and the second workpiece 300, which can keep the positions of the first workpiece 200 and the second workpiece 300 accurate and facilitate unified conveying. The conveying mechanism 10 can transport the tray 1b loaded with a plurality of first workpieces 200 from the upstream to near the handling mechanism 20 to facilitate the handling mechanism 20 to carry the tray 1b. The handling mechanism 20 can place the tray 1b loaded with the completed-connected first workpiece 200 and second workpiece 300 on the conveying mechanism 10 to facilitate the conveying mechanism 10 to transport it to the downstream.

[0102] The transportation mechanism 10 includes a transportation component 11 and a material lifting component 12. The transportation component 11 is used to transport the pallet 1b, and the material lifting component 12 is used to lift the pallet 1b on the transportation component 11 so that the handling mechanism 20 can remove the pallet 1b on the material lifting component 12. The handling mechanism 20 can place the pallet 1b loaded with the first workpiece 200 and the second workpiece 300 on the material lifting component 12, and place the pallet 1b on the transportation component 11 through the material lifting component 12. The handling mechanism 20 can also directly place the pallet 1b on the transportation component 11 so that the transportation component 11 transports the pallet 1b to the downstream.

[0103] The transportation component 11 includes a transportation main body 111 and a conveyor belt 112. The conveyor belt 112 is wound around the transportation main body 111. The transportation main body 111 is used to drive the conveyor belt 112 to rotate. The pallet 1b can be placed on the conveyor belt 112 and at least partially exposed outside the conveyor belt 112. The rotation of the conveyor belt 112 drives the pallet 1b to be transported. The material lifting component 12 is connected to the transportation main body 111 and is used to lift the part of the pallet 1b exposed outside the conveyor belt 112 to lift the pallet 1b, or place the pallet 1b of the material lifting component 12 on the conveyor belt 112.

[0104] Optionally, in some embodiments, the transportation component 11 further includes a support plate 113. The support plate 113 is arranged on the transportation main body 111 and is located in the conveyor belt 112. When the pallet 1b is placed on the conveyor belt 112, the gravity of the pallet 1b will press down the conveyor belt 112. The support plate 113 can prevent the conveyor belt 112 from bending downward to keep the position of the conveyor belt 112 stable. It reduces the situation that the pallet 1b is located too low, so that the material lifting component 12 cannot lift the pallet 1b due to the position deviation of the pallet 1b. Since the support plate 113 is located in the conveyor belt 112, there will be a gap between the bottom surface of the pallet 1b placed on the conveyor belt 112 and the upper surface of the support plate 113. Thus, the material lifting component 12 can lift both sides of the pallet 1b exposed outside the conveyor belt 112 through this gap.

[0105] The material lifting component 12 includes a material lifting frame 122 and a lifting and material lifting member 121. The lifting and material lifting member 121 is arranged on the transportation main body 111, and the material lifting frame 122 is arranged on the lifting and material lifting member 121. The lifting and material lifting member 121 is used to drive the material lifting frame 122 to move vertically to control the lifting and lowering of the material lifting frame 122. The material lifting frame 122 is used to cooperate with the pallet 1b so that the pallet 1b is driven to move through the material lifting frame 122. Optionally, the lifting and material lifting member 121 is a cylinder.

[0106] The material lifting frame 122 includes a stop block 1221, a material lifting rod 1222 and a connecting rod 1223. The connecting rod 1223 is disposed substantially horizontally and extends in a direction perpendicular to the transport direction of the conveyor belt 112. The material lifting rod 1222 extends in the transport direction of the conveyor belt 112 and is connected to the connecting rod 1223. The number of the connecting rod 1223 and the material lifting rod 1222 is two each, so that the shape of the material lifting frame 122 is substantially rectangular. The cross-sectional shape of the material lifting rod 1222 is substantially L-shaped, and the two material lifting rods 1222 are symmetrically arranged. The bottom of the material lifting rod 1222 is substantially flush with the conveyor belt 112. When the tray 1b moves to the position of the material lifting frame 122, the bottom of the material lifting rod 1222 is located below the tray 1b, so that the tray 1b can be lifted when the material lifting rod 1222 rises. The stop block 1221 is disposed on the connecting rod 1223 closer to the downstream among the two connecting rods 1223, and contacts the tray 1b through the stop block 1221 to position the tray 1b. The number of the lifting and material lifting members 121 is also two, and each lifting and material lifting member 121 is connected to a connecting rod 1223.

[0107] The lifting and material lifting member 121 extends out to lower the material lifting frame 122. The tray 1b is transported along the conveyor belt 112 to the material lifting frame 122 and contacts the stop block 1221. At this time, the bottom of the material lifting rod 1222 is located at the bottom of the tray 1b. The lifting and material lifting member 121 retracts to lift the tray 1b by driving the material lifting frame 122, so that the position of the tray 1b can be defined, and the handling mechanism 20 can accurately handle the tray 1b. Further, the tray 1b can be lifted in time by the material lifting assembly 12, so that the transport assembly 11 can continuously operate and transport the tray 1b, reducing the start-stop times of the transport assembly 11 and extending the service life of the transport assembly 11. After the material lifting frame 122 lifts the tray 1b, the handling mechanism 20 handles the tray 1b.

[0108] Please refer to Figure 7 、 Figure 8 and Figure 9 As shown in, the handling mechanism 20 includes a workpiece handling member 21, a tray handling member 22 and a power member 23. The power member 23 is located on one side of the transport mechanism 10. The workpiece handling member 21 and the tray handling member 22 are connected to the power member 23, and the workpiece handling member 21 is located on one side of the tray handling member 22. The power member 23 drives the workpiece handling member 21 and the tray handling member 22 to move. The tray handling member 22 is used to handle the tray 1b, and the workpiece handling member 21 is used to handle the first workpiece 200 or the first workpiece 200 and the second workpiece 300. The handling mechanism 20 can handle both the tray 1b and the first workpiece 200 or the first workpiece 200 and the second workpiece 300. The handling mechanism 20 has three handling functions, which can improve the utilization rate of the handling mechanism 20 and save costs.

[0109] The tray handling member 22 includes a suction cup 221 and a tray mounting plate 222. The tray mounting plate 222 is disposed on the power member 23, and the suction cup 221 is disposed on one side of the tray mounting plate 222. The suction cup 221 is connected to the power member 23 through the tray mounting plate 222. The suction cup 221 can directly adsorb the tray 1b to remove the tray 1b with the first workpiece 200 placed thereon from the handling mechanism 20, or place the tray 1b with the first workpiece 200 and the second workpiece 300 placed thereon on the handling mechanism 20. Optionally, the number of suction cups 221 is four and they are located at the four corners of the tray mounting plate 222 to increase the contact area between the suction cup 221 and the tray 1b, so that the tray handling member 22 can handle the tray 1b more stably. It can be understood that the method of handling the tray 1b is not limited to adsorption by the suction cup 221, and it can also be other methods. For example, if the tray 1b includes metal parts such as iron, the tray handling member 22 is an electromagnet and can adsorb the tray 1b, etc.

[0110] The workpiece handling member 21 includes a first suction head 211 and a suction head mounting plate 212. The suction head mounting plate 212 is disposed on the power member 23 and is located on one side of the tray mounting plate. The first suction head 211 is disposed on one side of the suction head mounting plate 212. The shape of the first suction head 211 is similar to the receiving groove 10b of the tray 1b, so that the first suction head 211 can extend into the receiving groove 10b to adsorb and remove the first workpiece 200 on the tray 1b, or after the second workpiece 300 is attached to the first workpiece 200, move the first workpiece 200 and the second workpiece 300 onto the tray 1b. Optionally, the number of the first suction heads 211 is multiple, and the multiple first suction heads 211 are arranged along the length direction of the suction head mounting plate 212 to facilitate adsorbing multiple first workpieces 200 at one time.

[0111] Optionally, in some embodiments, the film laminating device 100 further includes a frame 1a. The frame 1a is located on the side of the power member 23 away from the transport mechanism 10. The frame 1a includes a positioning frame 10a for positioning the tray 1b. The positioning frame 10a is located on one side of the transport mechanism 10. The material transfer mechanism 30 is disposed on the frame 1a and is located on one side of the handling mechanism 20. It can be understood that the position between the positioning frame 10a and the transport mechanism 10 is not limited as long as the handling mechanism 20 can transport the tray 1b back and forth between the positioning frame 10a and the transport mechanism 10.

[0112] After the tray carrier 22 removes the pallet 1b on the transport mechanism 10, it can transport it to the positioning rack 10a. Then, the workpiece carrier 21 removes the first workpiece 200 on the positioning rack 10a and transports it to the material transfer mechanism 30. When the second workpiece 300 adheres to the first workpiece 200 and is pressed, the workpiece carrier 21 can remove the first workpiece 200 and the second workpiece 300 from the material transfer mechanism 30 and place them on the pallet 1b on the positioning rack 10a. The tray carrier 22 can transport the pallet 1b with the first workpiece 200 and the second workpiece 300 to the transport mechanism 10, so that the transport mechanism 10 transports the pallet 1b to the downstream. Thus, the pallets 1b flowing down from the upstream will not accumulate on the transport mechanism 10 for a long time, which can improve the transport efficiency. And multiple positioning racks 10a can be set to further relieve the accumulation of pallets 1b on the transport mechanism 10.

[0113] The positioning rack 10a includes a bracket 12a and a positioning member 11a. The bracket 12a is located on one side of the transport mechanism 10 and at one end of the material transfer mechanism 30. The positioning member 11a is arranged on the bracket 12a and is used to position the pallet 1b. The material of the pallet 1b is plastic, and a receiving groove 10b is formed by thermoforming, so that a protrusion having the same shape as the receiving groove 10b is formed at the bottom of the pallet 1b. A profiling groove 111a is provided on the positioning member 11a, and the shape of the profiling groove 111a is the same as that of the protrusion. Therefore, when the pallet 1b is placed on the positioning member 11a, the protrusion of the pallet 1b is located in the profiling groove 111a to achieve positioning. Optionally, the structure of the positioning member 11a is the same as that of the pallet 1b to reduce the types of parts, facilitate maintenance or replacement. And since there are multiple receiving grooves 10b on the pallet 1b, there are multiple positioning points between the positioning member 11a and the pallet 1b, and the positioning accuracy of the pallet 1b is high.

[0114] Please refer to Figure 10, the material transfer mechanism 30 includes a material transfer component 31 and a jig 32. The material transfer component 31 is disposed on the frame 1a and extends along the first direction X. The jig 32 is disposed on the material transfer component 31 and is used to drive the jig 32 to reciprocate along the first direction X. The material transfer component 31 has a loading / unloading position 311, a pressing position 314, an attaching position 312, and a bending position 313 arranged in sequence along the first direction X. The loading / unloading position 311 is adjacent to the handling mechanism 20. When the jig 32 moves to the loading / unloading position 311, the workpiece handling member 21 can place the first workpiece 200 on the positioning member 11a onto the jig 32, or place the first workpiece 200 and the second workpiece 300 on the jig 32 onto the positioning member 11a. When the jig 32 moves to the attaching position 312, the attaching mechanism 50 attaches the second workpiece 300 to the first workpiece 200 on the jig 32. When the jig 32 moves to the bending position 313, the functional mechanism 70 takes out the first workpiece 200 and the second workpiece 300 in the jig 32, and the functional mechanism 70 places the first workpiece 200 and the bent second workpiece 300 into the jig 32. When the jig 32 moves to the pressing position 314, the pressing mechanism 90 presses the first workpiece 200 and the second workpiece 300 in the jig 32. It can be understood that the positional relationship between the loading / unloading position 311, the pressing position 314, the attaching position 312, and the bending position 313 is not limited. For example, the loading / unloading position 311 is located at one end of the material transfer component 31 away from the transport mechanism 10.

[0115] Optionally, the number of the material transfer mechanisms 30 is two. The two material transfer mechanisms 30 are arranged at intervals along the second direction Y. One of the material transfer mechanisms 30 is used to move away from the transport mechanism 10 to process the first workpiece 200 and the second workpiece 300. The other material transfer mechanism 30 is used to move towards the transport mechanism 10 to transport the processed first workpiece 200 and the workpiece to the transport mechanism 10.

[0116] Optionally, the material transfer component 31 is a lead screw slide table. The jig 32 is disposed on the slide table, and the slide table reciprocates along the first direction X under the rotation of the lead screw. The jig 32 is provided with a placement groove 321 for placing the first workpiece 200 and / or the second workpiece 300. The shape of the placement groove 321 is the same as the shape of the accommodation groove 10b and the profiling groove 111a. Optionally, the number of the placement grooves 321 is multiple. The multiple placement grooves 321 are divided into two rows. Each row of placement grooves 321 is arranged at intervals along the first direction X, and the two rows of placement grooves 321 are arranged at intervals along the second direction Y. The second direction Y is perpendicular to the first direction X, and the plane formed by the first direction X and the second direction Y is horizontal, so that multiple first workpieces 200 and second workpieces 300 can be placed on the jig 32 simultaneously.

[0117] Each placement slot 321 has a guiding part 3211 and a placement part 3212. The guiding part 3211 and the placement part 3212 are in communication with each other. The guiding part 3211 is located above the placement part 3212. The shape of the guiding part 3211 is the same as that of the placement part 3212, and the size of the guiding part is larger than that of the placement part 3212. That is, in the direction of the vertical projection, the placement part 3212 is completely located within the guiding part 3211. When the first workpiece 200 or the first workpiece 200 and the second workpiece 300 are placed in the placement slot 321, the first workpiece 200 or the first workpiece 200 and the second workpiece 300 first pass through the guiding part 3211. Due to the large size of the guiding part 3211, even if there is an error in the position of the first workpiece 200 or the first workpiece 200 and the second workpiece 300, they can be placed within the guiding part 3211. The first workpiece 200 located within the guiding part 3211 can be located within the placement part 3212 under the guidance of the guiding part 3211 to accurately position the workpiece. Optionally, the groove wall of the guiding part 3211 is inclined relative to the vertical direction, so that along the vertically downward direction, the guiding part 3211 gradually contracts.

[0118] In some embodiments, the accommodating slot 10b of the tray 1b is the same as the placement slot 321, and also has a guiding part 3211 and a placement part 3212. In other embodiments, the accommodating slot 10b of the tray 1b can also be different from the placement slot 321. For example, the tray 1b only includes the placement part 3212.

[0119] Please refer to Figure 10 and Figure 11 , after the jig 32 moves to the loading and unloading position 311, the handling mechanism 20 transports the first workpiece 200 into the jig 32. Subsequently, the jig 32 moves to the attaching position 312, and the attaching mechanism 50 takes out the second workpiece 300 from the coil mechanism 40 and attaches the second workpiece 300 to the first workpiece 200.

[0120] The coil mechanism 40 is arranged on the frame 1a and is located between the two material transfer mechanisms 30, and extends along the first direction X. It is used to move the rolled second workpiece 300 along the first direction X towards the direction close to the transport mechanism 10. A protective film 400 is provided on the second workpiece 300. The protective film 400 is a single layer and is attached to the upper side of the second workpiece 300. The coil mechanism 40 has a material taking platform 41. When the second workpiece 300 moves to the material taking platform 41, the attaching mechanism 50 takes out the second workpiece 300 and attaches it to the first workpiece 200 on the jig 32.

[0121] The attaching mechanism 50 includes a transfer component 51 and an attaching component 52. The transfer component 51 is arranged on the frame 1a, and the attaching component 52 is arranged on the transfer component 51. The transfer component 51 is used to drive the attaching component 52 to move along the first direction X, the second direction Y, and the third direction Z, so that the attaching component 52 can adsorb the second workpiece 300 and accurately attach the second workpiece 300 to the first workpiece 200 after adjusting the position.

[0122] The transfer component 51 includes a first transfer unit 511, a second transfer unit 512, and a third transfer unit 513. The first transfer unit 511 extends along the first direction X. The second transfer unit 512 extends along the second direction Y and is arranged on the first transfer unit 511. The third transfer unit 513 extends along the third direction Z, and the third direction Z is vertically arranged. The third transfer unit 513 is arranged on the second transfer unit 512, and the attaching component 52 is connected to the third transfer unit 513. The first transfer unit 511 is used to drive the attaching component 52 to reciprocate along the first direction X, the second transfer unit 512 is used to drive the attaching component 52 to reciprocate along the second direction Y, and the third transfer unit 513 is used to drive the attaching component 52 to move along the third direction Z. Optionally, the first transfer unit 511, the second transfer unit 512, and the third transfer unit 513 are all linear guides, and the transfer component 31 is a three-axis gantry module.

[0123] The process of attaching the second workpiece 300 to the first workpiece 200 is as follows: The first transfer unit 511 drives the attaching component 52 along the first direction X towards the material taking platform 41, so that the attaching component 52 is located above the second workpiece 300. The third transfer unit 513 drives the attaching component 52 to move downward and then move upward again after taking out the second workpiece 300. The second workpiece 300 on the attaching component 52 is positioned by the vision positioning mechanism 60, and the position of the second workpiece 300 is corrected by the first transfer unit 511 and the second transfer unit 512. The first transfer unit 511 drives the attaching component 52 towards the attaching position 312, so that the attaching component 52 is located above the fixture 32. The first workpiece 200 in the fixture 32 is positioned by the vision positioning mechanism 60, and the position of the second workpiece 300 on the attaching component 52 is adjusted correspondingly through the first transfer unit 511 and the second transfer unit 512, so that the second workpiece 300 corresponds to the first workpiece 200. The third transfer unit 513 drives the attaching component 52 to move downward, so that after the second workpiece 300 is attached to the first workpiece 200, it then drives the attaching component 52 to reset.

[0124] Please refer to Figure 12, the attaching assembly 52 includes an attaching head 521 and a rotating member 522. The rotating member 522 is disposed on the third material transfer unit 513, and the attaching head 521 is disposed at the lower end of the rotating member 522. The rotating member 522 is used to drive the attaching head 521 to rotate about the third direction Z. Since the sizes of the first workpiece 200 and the second workpiece 300 are small and the position accuracy required for attachment is high, by driving the attaching head 521 to rotate through the rotating member 522, the attachment accuracy of the second workpiece 300 to the first workpiece 200 can be further improved, so as to improve the product yield.

[0125] The attaching head 521 includes a connecting block 5211, a connecting spring 5212 and an attaching block 5213. The connecting block 5211 is disposed at the lower end of the rotating member 522. One end of the connecting spring 5212 is connected to the connecting block 5211, and the other end is connected to the attaching block 5213. The attaching block 5213 is used to adsorb the second workpiece 300 and attach the second workpiece 300 to the first workpiece 200. By providing the connecting spring 5212, when the attaching block 5213 picks up the second workpiece 300 and when attaching the second workpiece 300 to the first workpiece 200, the attaching block 5213 compresses the connecting spring 5212, and the connecting spring 5212 applies an elastic force to the attaching block 5213, so that the attaching block 5213 can pick up the second workpiece 300 or attach the second workpiece 300 more stably.

[0126] Optionally, the number of the attaching assemblies 52 is two, and the two attaching assemblies 52 are arranged at intervals along the second direction Y, so as to increase the attaching efficiency of the attaching assembly 52.

[0127] During the process of attaching the second workpiece 300 to the first workpiece 200, it is necessary to position the first workpiece 200 and the second workpiece 300 respectively through the vision positioning mechanism 60. The vision positioning mechanism 60 includes a fixed camera assembly 61 and a moving camera assembly 62. The fixed camera assembly 61 is disposed on the frame 1a and is located on one side of the material taking platform 41 for positioning the second workpiece 300. The moving camera assembly 62 is disposed on the third material transfer unit 513 for positioning the first workpiece 200.

[0128] After the attaching head 521 picks up the second workpiece 300 from the picking platform 41, it moves to the imaging position driven by the transfer assembly 51. The fixed imaging assembly 61 acquires an image of the second workpiece, and compares the image of the second workpiece with a preset image of the second workpiece to confirm the position error of the second workpiece 300 located on the attaching head 521 at this time. Then, according to this position error, the position of the attaching head 521 is correspondingly adjusted through the first material transfer unit 511, the second material transfer unit 512 and the rotating member 522, so as to adjust the position of the second workpiece 300, making the position of the second workpiece 300 consistent with the preset position of the second workpiece 300. Optionally, the preset image of the second workpiece can be taken during equipment calibration, or can be taken manually during the pause of the equipment operation. The image of the second workpiece can be a photo taken by the fixed imaging assembly 61, or a real-time picture taken by the fixed imaging assembly 61.

[0129] After the position of the second workpiece 300 is adjusted, the attaching head 521 drives the second workpiece 300 to move to the attaching position 312 through the first transfer unit, so that the moving imaging assembly 62 is located above the fixture 32. The moving imaging assembly 62 acquires an image of the first workpiece 200 in the placement groove 321 of the fixture 32. By comparing the image of the first workpiece 200 with a preset image of the first workpiece 200, the position error of the first workpiece 200 on the attaching head 521 is confirmed at this time. Then, according to this error, the position of the attaching head 521 is correspondingly adjusted through the first material transfer unit 511, the second material transfer unit 512 and the rotating member 522, so as to adjust the position of the second workpiece 300, offsetting the position error of the first workpiece 200, so that the second workpiece 300 can be accurately attached to the first workpiece 200. By sequentially confirming the positions of the second workpiece 300 and the first workpiece 200, two position corrections are performed on the second workpiece 300, which can effectively improve the position accuracy of the second workpiece 300 attached to the first workpiece 200, so as to improve the yield rate.

[0130] Please refer to Figure 13 and Figure 14 , after attaching the second workpiece 300 to the first workpiece 200, the fixture 32 moves to the bending position 313, and the functional mechanism 70 takes out the first workpiece 200 and the second workpiece 300 in the fixture 32 and places them on the limiting mechanism 80.

[0131] The functional mechanism 70 is located at one end of the material transfer mechanism 30 away from the handling mechanism 20. The functional mechanism 70 includes a driving member 74 and a material picking assembly. The material picking assembly is arranged on the driving member 74, and the driving member 74 drives the material picking assembly to move, so that the material picking assembly can take out the first workpiece 200 and the second workpiece 300 of the fixture 32 and place them on the limiting mechanism 80. The material picking assembly includes a plurality of second suction heads 72, and the plurality of second suction heads 72 are arranged in a row for taking out a plurality of first workpieces 200 and second workpieces 300 at one time.

[0132] The first workpiece 200 and the second workpiece 300 placed in the limiting mechanism 80 at least partially extend out of the limiting mechanism 80, so that the second surface 202 of the first workpiece 200 is located outside the limiting mechanism 80. Accordingly, the functional mechanism 70 further includes a bending component 71, and the bending component 71 is connected to the driving member 74. The driving member 74 can drive the bending component 71 to move, so that the bending component 71 can bend the second workpiece 300 and attach it to the first workpiece 200.

[0133] The bending component 71 includes a U-shaped block 712 and a roller 711. The U-shaped block 712 is arranged on the driving member 74, and the roller 711 is rotatably arranged on the U-shaped block 712. The roller 711 can rotatably press against the second workpiece 300, so that when the second workpiece 300 presses against the first workpiece 200 and the second workpiece 300, the second workpiece 300 can rotate relative to the first workpiece 200, and a pressure is applied to the second workpiece 300 so that the second workpiece 300 can be attached to the first workpiece 200. When the roller 711 presses against the second workpiece 300, the extending direction of the rotation axis of the roller 711 forms an angle greater than 0° with the extending direction of the first workpiece 200 and the second workpiece 300 at least partially extending out of the limiting mechanism 80, so that when the roller 711 rolls on the first workpiece 200 and the second workpiece 300, the roller 711 can roll on the first workpiece 200 or the second workpiece 300.

[0134] Please refer to Figure 15 , optionally, in some embodiments, the first workpiece 200 and the second workpiece 300 extend out of the limiting mechanism 80 along the second direction Y. When the roller 711 presses against the second workpiece 300, the rotation axis of the roller 711 extends along the first direction X. At this time, the extending direction of the first workpiece 200 and the second workpiece 300 is perpendicular to the extending direction of the rotation axis of the roller 711. It can be understood that the extending direction of the workpiece and the extending direction of the rotation axis of the roller 711 are not limited to being perpendicular, and can also be other angles, such as 70°, 80°, etc. The formed angle can be on the horizontal plane or not on the horizontal plane.

[0135] The process of the roller 711 bending the second workpiece 300 is as follows: The driving member 74 drives the roller 711 to move above the limiting mechanism 80 and presses against the limiting mechanism 80. The roller 711 rolls along the protruding part moving in the second direction Y towards the first workpiece 200 and the second workpiece 300. During the rolling of the roller 711 in the second direction Y, it rolls and presses the first workpiece 200 and the second workpiece 300. When the roller 711 rolls to the edge of the protruding part of the first workpiece 200, the roller 711 moves downward to bend the second workpiece 300. When the roller 711 rolls downward, the distance between the axis of rotation of the roller 711 and the edge of the protruding part of the first workpiece 200 is less than the radius of the roller 711, so that the roller 711 undergoes elastic deformation during the downward rotation. During the process of the roller 711 bending the second workpiece 300, in addition to applying a downward pressure on the second workpiece 300, the roller 711 also applies an inclined component force to the second workpiece 300. The direction of the component force is towards the first workpiece 200 and is inclined downward, so that the second workpiece 300 can adhere to the second surface 202 of the first workpiece 200.

[0136] By rolling and bending the second workpiece 300 with the roller 711 and applying an inclined component force to the second workpiece 300, the second workpiece 300 can be completely adhered to the arc surface, improving the yield rate and reducing the situation where there is a gap between the second workpiece 300 and the first workpiece 200 when the second workpiece 300 adheres to the first workpiece 200. Optionally, the roller 711 is made of a material that can undergo elastic deformation, such as rubber, silica gel, foam, etc.

[0137] It can be understood that the rolling process of the roller 711 is not limited to first rolling in the second direction Y and then rolling downward. In other embodiments, the driving member 74 can also drive the roller 711 to move to the edge of the first workpiece 200 and drive the roller 711 to move downward, so that the roller 711 bends the second workpiece 300 and adheres to the second surface 202 of the first workpiece 200. It can be understood that the second surface 202 of the first workpiece 200 can be arc-shaped or flat, and can form an angle with the first surface 201 or be in the same plane as the first surface 201.

[0138] Please refer to Figure 16The functional mechanism 70 also includes a film tearing assembly 73, which is connected to the driving member 74 and is located on one side of the film tearing assembly 73 located on the roller 711, and is used to tear the protective film 400. When the roller 711 bends the second workpiece 300, the protective film 400 is also bent along with the second workpiece 300. When the pressure of the roller 711 is released, the second workpiece 300 is bent and attached to the first workpiece 200, and the protective film 400 is elastically deformed and recovered and separated from the second workpiece 300. The driving member 74 can drive the film tearing assembly 73 to move to the protective film 400 and clamp the protective film 400. Then, under the action of the driving member 74, the film tearing assembly 73 tears the protective film 400 from the second workpiece 300. The protective film 400 is separated from the second workpiece 300 by recovering the elastic deformation of the protective film 400, and the film tearing process is simple and convenient.

[0139] The film tearing assembly 73 includes a clamping cylinder 731 and a clamping block 732. The clamping cylinder 731 is located on one side of the roller 711. Each clamping cylinder 731 is connected to two clamping blocks 732. The clamping cylinder 731 drives the two clamping blocks 732 to move closer to each other to clamp the protective film 400 or drives the two clamping blocks 732 to move away from each other to release the protective film 400. Optionally, there are multiple film tearing assemblies 73, and the direction in which the multiple film tearing assemblies 73 are spaced apart is parallel to the extension direction of the axis of the roller 711, and the number of the bending assemblies 71, the second suction head 72 and the film tearing assemblies 73 is the same.

[0140] Please refer to Figure 16 The limiting mechanism 80 includes a limiting frame 81 and a limiting member 82. The limiting member 82 is arranged on the frame 1a and is adjacent to the bending position 313. The limiting frame 81 is provided with a through slot 811. The opening of the through slot 811 is located on the upper surface of the limiting frame 81 and penetrates one side of the limiting frame 81. The through slot 811 is used to place the first workpiece 200 and the second workpiece 300. When the first workpiece 200 and the second workpiece 300 are located in the through slot 811, the first workpiece 200 and the second workpiece 300 extend from one side of the limiting frame 81. The limiting member 82 is arranged on the frame 1a and is connected to the limiting frame 81, and is used to limit the position of the first workpiece 200 and the second workpiece 300 on the through slot 811. Optionally, the shape of the limiting member 82 is roughly 冂-shaped.

[0141] Optionally, the number of through slots 811 is multiple and forms two rows, the two rows of through slots 811 are arranged at intervals along the second direction Y, and the multiple through slots 811 in each row are arranged at intervals along the first direction X. The driving member 74 can drive the roller 711 to move onto the limiting frame 81 and be located between the two rows of through slots 811, and the roller 711 moves in two directions along the second direction Y to roll the first workpiece 200 and the second workpiece 300 on both sides respectively, so that the bending efficiency of the second workpiece 300 is high.

[0142] Optionally, in some embodiments, the through slot 811 is similar in structure to the placement slot 321, including a guiding portion 3211 and a placement portion 3212. The main difference is that one side of the through slot 811 penetrates through the limiting frame 81. This facilitates the placement of the first workpiece 200 and the second workpiece 300 in the through slot 811.

[0143] Optionally, in some embodiments, the limiting frame 81 is provided with an adsorption assembly (not shown in the figure). The adsorption assembly is located in the through slot 811 and is used to adsorb the first workpiece 200 and the second workpiece 300 to ensure the stable positions of the first workpiece 200 and the second workpiece 300. The adsorption assembly can be a suction cup 221, a magnet, or other structures capable of adsorbing the first workpiece 200 and / or the second workpiece 300.

[0144] After the first workpiece 200 and the second workpiece 300 are placed in the through slot 811, the limiting member 82 limits the positions of the first workpiece 200 and the second workpiece 300 to facilitate the bending of the second workpiece 300 by the roller 711. The limiting member 82 includes a limiting cylinder 821 and a limiting portion 822. The limiting cylinder 821 is disposed on the frame 1a and can pass through the limiting frame 81 and expand and contract vertically. The limiting portion 822 is disposed on the limiting cylinder 821 and is located above the limiting frame 81. The limiting cylinder 821 is used to drive the vertical movement of the limiting portion 822. When the piston rod of the limiting cylinder 821 extends, the limiting portion 822 is lifted upward to facilitate the placement of the first workpiece 200 and the second workpiece 300 in the through slot 811. Subsequently, the limiting cylinder 821 retracts to lower the limiting portion 822, and the limiting portion 822 cooperates with the limiting frame 81 to limit the positions of the first workpiece 200 and the second workpiece 300.

[0145] The limiting portion 822 includes a fixing plate 8221 and a plurality of limiting blocks 8222. The fixing plate 8221 extends along the first direction X. The plurality of limiting blocks 8222 are divided into two rows, and the two rows of limiting blocks 8222 are spaced along the second direction Y and are disposed on opposite sides of the fixing plate 8221. Each row of limiting blocks 8222 is spaced along the first direction X and corresponds to the position of the through slot 811. The positions of the first workpiece 200 and the second workpiece 300 are limited by pressing down the limiting blocks 8222.

[0146] Optionally, in some embodiments, the width of the limiting block 8222 along the first direction X is smaller than the width of the through slot 811 along the first direction X. The first workpiece 200 is provided with a plurality of grooves for installing electronic components or adapting to other components. By setting the width of the limiting block 8222 to be reduced, the limiting block 8222 can just avoid the grooves of the first workpiece 200, which can not only reduce the wear of the grooves on the first workpiece 200, but also reduce the interference between the first workpiece 200 and the electronic components if the electronic components are installed on the first workpiece 200 first.

[0147] Optionally, in some embodiments, when the piston rod of the limit cylinder 821 retracts so that the limit block 8222 presses down, there is a gap between the limit block 8222 and the first workpiece 200 instead of direct contact. The first workpiece 200 and the second workpiece 300 are positioned by the adsorption assembly, and the limit block 8222 is used to prevent the first workpiece 200 and the second workpiece 300 from separating from the through groove 811. Thus, the situation of scratching caused by the contact between the limit block 8222 and the first workpiece 200 or the second workpiece 300 is reduced.

[0148] In some other embodiments, after the limit block 8222 presses down, it presses against the first workpiece 200 to improve the stability of the first workpiece 200 and reduce the situation that the first workpiece 200 shakes and affects the attachment effect when the second workpiece 300 is bent.

[0149] After the bending assembly 71 bends the second workpiece 300 and the film tearing assembly 73 tears off the protective film 400, the second suction head 72 picks up the first workpiece 200 and the second workpiece 300 on the limiting mechanism 80 and places them on the fixture 32. The fixture 32 located at the bending position 313 moves to the pressing position 314, and the pressing mechanism 90 presses the first workpiece 200 and the second workpiece 300.

[0150] Please refer to Figure 17 and Figure 18 , the pressing mechanism 90 includes a pressing member 91 and a telescopic member 92. The telescopic member 92 is arranged on the frame 1a and is located above the pressing position 314. The pressing member 91 is connected to the telescopic member 92, and the telescopic member 92 is used to drive the pressing member 91 to move vertically so that the pressing member 91 presses the first workpiece 200 and the second workpiece 300. Optionally, the telescopic member 92 is a cylinder.

[0151] The pressing member 91 includes a connecting plate 911, a pressing block 912 and an elastic member 913. The connecting plate 911 is connected to the lower end of the telescopic member 92. One end of the elastic member 913 is connected to the connecting plate 911, and the other end is connected to the pressing block 912. When the pressing block 912 presses against the first workpiece 200 and the second workpiece 300, the elastic member 913 compresses so that the pressing block 912 can press against the first workpiece 200 and the second workpiece 300 more stably, improving the pressing effect. Optionally, the connecting plate 911 is provided with an avoidance groove (not marked in the figure), the elastic member 913 and a part of the pressing block 912 are located in the avoidance groove, and the lower end of the pressing block 912 extends out of the connecting block 5211 to facilitate pressing against the first workpiece 200 and the second workpiece 300. Optionally, the number of the elastic members 913 and the pressing blocks 912 is multiple and corresponds to the number and position of the placement grooves 321 of the fixture 32.

[0152] After the pressing mechanism 90 presses the first workpiece 200 and the second workpiece 300 together, the fixture 32 moves to the loading and unloading position 311, and the handling mechanism 20 places the first workpiece 200 and the second workpiece 300 on the tray 1b on the positioning frame 10a. When all the first workpieces 200 on the positioning frame 10a are attached with the second workpieces 300, the handling mechanism 20 removes the tray 1b on the positioning frame 10a and transports it to the transport mechanism 10, so that the transport mechanism 10 can transport the first workpiece 200 and the second workpiece 300 to the downstream.

[0153] Therefore, the attaching process of the film attaching device 100 of the present application is as follows: The transport component 11 transports the tray 1b carrying the first workpiece 200 from the upstream to the lifting component 12. After the lifting component 12 lifts the tray 1b, the handling mechanism 20 transports the tray 1b to the positioning frame 10a. The handling mechanism 20 removes the first workpiece 200 on the tray 1b and places it on the fixture 32. The fixture 32 moves from the loading and unloading position 311 to the attaching position 312. The attaching mechanism 50 takes out the second workpiece 300 from the material taking platform 41 and locates the position of the second workpiece 300 through the fixed camera component 61. The attaching mechanism 50 drives the second workpiece 300 to move to the attaching position 312, and the moving camera component 62 locates the position of the first workpiece 200, so that the transfer component 51 and the rotating part 522 correspondingly adjust the position of the second workpiece 300, making the position of the second workpiece 300 correspond to that of the first workpiece 200. The attaching mechanism 50 attaches the second workpiece 300 to the first workpiece 200. The fixture 32 moves from the attaching position 312 to the bending position 313. The functional mechanism 70 takes out the first workpiece 200 and the second workpiece 300 in the fixture 32 and places them on the limiting mechanism 80. After the limiting mechanism 80 limits the first workpiece 200 and the second workpiece 300, the bending mechanism of the functional mechanism 70 bends the second workpiece 300, so that a part of the second workpiece 300 adheres to the first surface 201 of the first workpiece 200, and the other part adheres to the second surface 202 of the first workpiece 200. The film tearing component 73 of the functional mechanism 70 tears off the protective film 400. The limiting mechanism 80 releases the limitation of the first workpiece 200 and the second workpiece 300. The material taking component of the functional mechanism 70 takes out the first workpiece 200 and the second workpiece 300 and places them on the fixture 32. The fixture 32 moves from the bending position 313 to the pressing position 314, and presses the first workpiece 200 and the second workpiece 300 together through the pressing mechanism 90. The fixture 32 moves from the pressing position 314 to the loading and unloading position 311, and the handling mechanism 20 transports the first workpiece 200 and the second workpiece 300 to the tray 1b on the positioning member 11a. When all the first workpieces 200 on the tray 1b are attached with the second workpieces 300, the handling mechanism 20 transports the tray 1b to the transport mechanism 10, and the transport mechanism 10 transports the first workpiece 200 and the second workpiece 300 to the downstream.

[0154] It can be understood that the process of attaching the second workpiece 300 to the first workpiece 200 described above is only one of the methods in the embodiments of the present application, and is only for the convenience of understanding the technical solution of the present application, and does not represent the entire protection scope of the present application.

[0155] In summary, the film attaching device 100 provided in the embodiments of the present application can attach the second workpiece 300 to the first workpiece 200. The second workpiece 300 is bent by the roller 711, and during the process of pressing against the second workpiece 300, an inclined downward component force can be applied to the second workpiece 300 through the elastic deformation and rolling of the roller 711, so that the second workpiece 300 is completely attached to the first workpiece 200. After the second workpiece 300 is bent, the protective film 400 is separated from the second workpiece 300, and the film tearing assembly 73 can simply and quickly tear the protective film 400.

[0156] In addition, those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as it is within the scope of the spirit of the present application, appropriate changes and variations made to the above embodiments fall within the scope disclosed in the present application.
