Description

Technical Field

[0001] This application relates to the field of automation equipment technology, specifically to a film application device. Background Technology

[0002] During the production of workpieces, a film needs to be applied to the surface of the workpieces. Currently, this is often done manually. The speed and accuracy of manual film application are related to the skill level of the operator, resulting in inconsistent film quality. Furthermore, manual film application is labor-intensive and inefficient. Summary of the Invention

[0003] In view of the above, it is necessary to propose a film-applying device to replace manual film application, thereby reducing labor intensity and achieving better film application results.

[0004] This application provides a film-applying device for applying a film to a workpiece. The film-applying device includes: a feeding module for providing the workpiece to be film-applied; and a film-applying module adjacent to the feeding module, the film-applying module including a material-carrying mechanism, and a transfer mechanism, a film-tearing mechanism, a film-removing mechanism, and a film-pressing mechanism arranged sequentially above the material-carrying mechanism along a first direction; the material-carrying mechanism includes a motion component and a material-carrying assembly disposed on the motion component, the material-carrying assembly having a material-carrying position for carrying the workpiece; the film-removing mechanism is used to apply the film to the workpiece. The film is placed at the loading position; the film-tearing mechanism is used to tear the film placed at the loading position so that the opening of the film faces the transfer mechanism; the transfer mechanism is used to transfer the workpiece into the torn film carried by the loading mechanism, and the loading mechanism is also used to move the workpiece and the film along the first direction so that the pressing mechanism rolls the film and the workpiece to adhere the film to the workpiece; and a feeding module is disposed adjacent to the film-receiving mechanism for collecting the workpiece after the film is adhered.

[0005] The aforementioned film-applying equipment provides workpieces to be film-applied via a feeding module. The material-carrying mechanism within the film-applying module moves the material-carrying component below the film-taking mechanism via a motion component. The film-taking mechanism places the film onto the material-carrying position of the material-carrying component. Then, the motion component moves the film to below the film-tearing mechanism via the material-carrying component. The film-tearing mechanism tears the film from the material-carrying position, aligning the opening of the film with the transfer mechanism. The transfer mechanism transfers the workpiece provided by the feeding module into the film. The material-carrying component then moves the workpiece and film towards the film-pressing mechanism, while the film-tearing mechanism simultaneously releases the film. The material-carrying component moves the workpiece and film past under the film-pressing mechanism, which rolls the film and workpiece to adhere the film to the workpiece. After the workpiece with the film adhered passes the film-pressing mechanism, the unloading module removes and collects the workpiece from the material-carrying component. The aforementioned film-applying equipment, through the cooperation of the feeding module, film-applying module, and unloading module, can automatically apply film to workpieces and collect the film-applied workpieces, reducing labor intensity, improving film-applying efficiency, and reducing labor costs.

The plurality of telescopic grippers are all connected to the material transfer frame and are used to grasp the workpiece on the positioning unit. Driven by the first displacement drive, the material transfer frame moves along the first direction, thereby placing the workpiece on the loading mechanism.

[0009] In some embodiments, the material loading assembly includes a plurality of suction discs, each suction disc having a material loading position and a vacuum hole extending to the material loading position.

The first longitudinal drive member drives the film-tearing grippers to move in a third direction, so that when the suction tray moves below the film-tearing frame, the film-tearing grippers hold the upper film. When the suction tray moves in the opposite direction to the first direction, the film-tearing grippers hold the upper film and move along the third direction, thereby tearing the upper film and the lower film of the film component apart. The third direction is perpendicular to both the first direction and the second direction.

[0011] In some embodiments, the film-tearing mechanism further includes a rotating assembly, which includes a connector, a rotating plate, and a rotating drive. The connector is connected to the output end of the first longitudinal drive. The rotating plate is rotatably connected to the connector. The film-tearing gripper is connected to the rotating plate. The rotating drive is connected to the connector, and the output end of the rotating drive is connected to the rotating plate. The rotating drive is used to drive the rotating plate to rotate, thereby causing the film-tearing gripper to rotate.

[0012] In some embodiments, the film-grabbing mechanism further includes a film frame, a second longitudinal drive member, a connecting plate, a plurality of rotary drive members, and a plurality of film-grabbing grippers.

The feeding component picks up the workpiece from the tray located on the conveying component and places the workpiece on the transfer mechanism. The tray receiving component is located at the end of the conveying component along the second direction and is used to collect the trays conveyed by the conveying component.

[0015] In some embodiments, the tray dispensing assembly includes a tray positioning member and a clamping and lifting member. The tray positioning member is fixedly connected to the conveying assembly for positioning the tray. The clamping and lifting member is fixedly connected to the conveying assembly and is correspondingly disposed to the tray positioning member. The clamping and lifting member is inserted between the trays of the lowest layer and the second-to-last layer to lift the trays other than the tray of the lowest layer, thereby leaving the tray of the lowest layer on the conveying assembly. The conveying assembly then conveys the tray of the lowest layer along the second direction.

[0016] In some embodiments, the feeding assembly includes a second displacement drive, a transfer frame, a plurality of pitch-changing drive components, and a plurality of feeding grippers. The second displacement drive is disposed between the conveying assembly and the transfer mechanism. The transfer frame is connected to the second displacement drive, the pitch-changing drive is connected to the transfer frame, and the feeding grippers are connected to the pitch-changing drive.

[0089] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0090] The embodiments of this application will be further described below with reference to the accompanying drawings. For ease of explanation, please refer to... Figure 1 The first direction is defined as the X-axis direction, the second direction as the Y-axis direction, and the third direction as the Z-axis direction.

[0091] Please see Figure 1 and Figure 2 This application provides a film-applying device 100 for applying a film 200 to a workpiece 300. The film-applying device 100 includes a feeding module 10, a film-applying module 20, and a discharging module 30.

[0092] Specifically, the feeding module 10 is used to provide the workpiece 300 to be coated with film.

[0093] Please see Figure 2 The film-applying module 20 is adjacent to the feeding module 10. The film-applying module 20 includes a material-carrying mechanism 21, and a transfer mechanism 22, a film-tearing mechanism 23, a film-retrieving mechanism 24, and a film-pressing mechanism 25 arranged sequentially above the material-carrying mechanism 21 along the X-axis. The material-carrying mechanism 21 includes a motion component 211 and a material-carrying component 212 disposed on the motion component 211. The material-carrying component 212 is provided with a material-carrying position 2121 for carrying the workpiece 300. The film-retrieving mechanism 24 is used to place the film 200 in the material-carrying position 2121. The film-tearing mechanism 23 is used to tear the film 200 placed in the material-carrying position 2121 so that the opening of the film 200 faces the transfer mechanism 22. The transfer mechanism 22 is used to transfer the workpiece 300 into the torn film 200 carried by the loading mechanism 21. The loading mechanism 21 is also used to move the workpiece 300 and the film 200 along the X-axis direction so that the pressing mechanism 25 rolls the film 200 and the workpiece 300 and then attaches the film 200 to the workpiece 300.

[0094] The unloading module 30 is adjacent to the film taking mechanism 24 and is used to collect the workpiece 300 after the film is bonded to the film 200.

[0095] The film-applying equipment 100 provided in this embodiment can provide a workpiece 300 to be film-applied via a feeding module 10. The material-carrying mechanism 21 in the film-applying module 20 can move the material-carrying component 212 via a motion component 211, moving the material-carrying component 212 below the film-taking mechanism 24. The film-taking mechanism 24 places the film 200 on the material-carrying position 2121 of the material-carrying component 212. Then, the motion component 211 moves the film 200 below the film-tearing mechanism 23 via the material-carrying component 212. The film-tearing mechanism 23 tears the film 200 on the material-carrying position 2121, making the opening of the film 200 face the transfer mechanism 22. The transfer mechanism 22 transfers the workpiece 300 provided by the feeding module 10 into the film 200. Then, the material-carrying component 212 moves the workpiece 300 and the film 200 towards the film-pressing mechanism 25, while the film-tearing mechanism 23 simultaneously releases the film 200. The material carrier assembly 212 carries the workpiece 300 and the film 200 past under the film pressing mechanism 25. The film pressing mechanism 25 rolls the film 200 and the workpiece 300, thus attaching the film 200 to the workpiece 300. After the workpiece 300 with the film 200 attached passes through the film pressing mechanism 25, the unloading module 30 removes the workpiece 300 from the material carrier assembly 212 and collects it. The film-applying equipment 100 provided in this embodiment, through the cooperation of the feeding module 10, the film-applying module 20, and the unloading module 30, can automatically apply film to the workpiece 300 and collect the film-applied workpiece 300, reducing labor intensity, improving film-applying efficiency, and reducing labor costs.

[0096] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 The transfer mechanism 22 includes a first positioning component 221 and a second positioning component 222 arranged adjacent to each other along the X-axis. Both the first positioning component 221 and the second positioning component 222 include a plurality of positioning units 223 arranged at intervals. The positioning units 223 are used to carry and position the workpiece 300. The first positioning component 221 is connected to a misalignment drive component 224. The misalignment drive component 224 is used to drive the first positioning component 221 to move along the Y-axis, so that the positioning units 223 on the first positioning component 221 and the positioning units 223 on the second positioning component 222 are misaligned in the Y-axis direction.

[0097] The first positioning component 221 may be provided with a plate-like support structure to stably support the positioning unit 223. The spacing between adjacent positioning units 223 on the first positioning component 221 corresponds to the loading position 2121 on the material transfer component 225. The positioning units 223 on the first positioning component 221 may be four, five, six, etc., and the specific number can be determined according to the number of workpieces 300 in the same row in the material tray 400, which is not limited here. The misalignment drive component 224 may be a cylinder, telescopic motor, etc. The first positioning component 221 may also be connected to a slide rail to limit the movement trajectory of the misalignment drive component 224 driving the first positioning component 221, thereby improving the accuracy of the movement position.

[0098] The second positioning component 222 may be provided with a plate-like support structure to stably support the positioning unit 223. The spacing between adjacent positioning units 223 on the second positioning component 222 corresponds to the loading position 2121 on the material transfer component 225. The second positioning component 222 may have four, five, six, or other positioning units 223. The specific number can be determined according to the number of workpieces 300 in the same row in the material tray 400, and is not limited here.

[0099] When the workpiece 300 is placed on the first positioning component 221 and the second positioning component 222, the positioning unit 223 on the first positioning component 221 and the positioning unit 223 on the second positioning component 222 are aligned in the X-axis direction. After the workpiece 300 is placed, the misalignment drive component 224 drives the first positioning component 221 to move in the Y-axis direction, so that the positioning unit 223 on the first positioning component 221 and the positioning unit 223 on the second positioning component 222 are misaligned in the X-axis direction, so that the transfer mechanism 22 can remove the workpiece 300 from the first positioning component 221 and the second positioning component 222.

[0100] In some embodiments, please refer to Figure 2 and Figure 3The positioning unit 223 includes a support member 2231, multiple fixed positioning members 2232, and multiple movable positioning members 2233. The support member 2231 supports the workpiece 300. The fixed positioning members 2232 protrude from the support member 2231. The movable positioning members 2233 are disposed on the support member 2231 and correspond to the fixed positioning members 2232. The movable positioning members 2233 are used to push the workpiece 300 on the support member 2231 towards the fixed positioning members 2232 to position the workpiece 300. The support member 2231 can be a plate-like structure to stably support the workpiece 300. The fixed positioning members 2232 can be column-like or block-like structures. There can be three or four fixed positioning members 2232, which can be disposed on two adjacent sides of the support member 2231. The movable positioning members 2233 can be cylinders, etc. There can be two or three movable positioning members 2233, which can be disposed on the other two sides of the support member 2231. When the workpiece 300 is placed on the support member 2231, the movable positioning member 2233 pushes the workpiece 300 against the fixed positioning member 2232, thereby positioning the workpiece 300.

[0101] In some embodiments, please refer to Figure 2 and Figure 5 The transfer mechanism 22 also includes a material transfer assembly 225, which includes a first displacement drive 2251, a material transfer frame 2252, and multiple telescopic grippers 2253 corresponding to multiple positioning units 223. The first displacement drive 2251 is adjacent to the first positioning assembly 221 and the second positioning assembly 222 along the Y-axis direction. The material transfer frame 2252 is connected to the first displacement drive 2251 and is mounted above the first positioning assembly 221 and the second positioning assembly 222. The first displacement drive 2251 is used to drive the material transfer frame 2252 to move in the X-axis direction. The multiple telescopic grippers 2253 are all connected to the material transfer frame 2252. The multiple telescopic grippers 2253 are used to grasp the workpiece 300 on the positioning unit 223 and move along the X-axis direction with the material transfer frame 2252 under the drive of the first displacement drive 2251, thereby placing the workpiece 300 on the loading assembly 212.

[0102] The first displacement drive component 2251 can be a linear guide rail, etc., and the transfer frame 2252 can be U-shaped. One leg of the transfer frame 2252 is connected to the first displacement drive component 2251, and the other leg can be connected to a slide rail, so that the first displacement drive component 2251 can drive the transfer frame 2252 to reciprocate in the X-axis direction. The number of telescopic grippers 2253 is consistent with the sum of the number of positioning units 223 on the first positioning component 221 and the second positioning component 222, so that multiple telescopic grippers 2253 can pick up the workpiece 300 on multiple positioning units 223. It can be understood that the telescopic grippers 2253 can be arranged side by side and two together. In each group of telescopic grippers 2253, the left telescopic gripper 2253 corresponds to the position of the positioning unit 223 on the second positioning component 222, and the right telescopic gripper 2253 corresponds to the position of the positioning unit 223 of the first positioning component 221 after moving along the Y-axis direction. Thus, when the transfer assembly 225 grips the workpiece 300, the first displacement drive 2251 drives the transfer frame 2252 to move in the opposite direction along the X-axis, so that the left telescopic claw 2253 in each set of telescopic claws 2253 corresponds to the position of the positioning unit 223 on the second positioning assembly 222. Then, the telescopic claw 2253 moves toward the workpiece 300 to grip the workpiece 300 on the second positioning assembly 222. Then, the first displacement drive 2251 drives the transfer frame 2252 to continue moving in the opposite direction along the X-axis, so that the right telescopic claw 2253 in each set of telescopic claws 2253 corresponds to the position of the positioning unit 223 of the first positioning assembly 221 after moving in the Y-axis direction. Then, the telescopic claw 2253 moves toward the workpiece 300 to grip the workpiece 300 on the first positioning assembly 221.

[0103] In some other embodiments, please refer to Figure 2 and Figure 5 The transfer mechanism 22 also includes an adjustment drive 226 and a mounting plate 227. The adjustment drive 226 is connected to the transfer rack 2252, and the mounting plate 227 is connected to the adjustment drive 226. Multiple telescopic grippers 2253 are connected to the mounting plate 227. The adjustment drive 226 drives the adjustment plate to move along the Y-axis, thereby causing the multiple telescopic grippers 2253 to move along the Y-axis to adjust and correct the position of the telescopic grippers 2253 in the Y-axis direction. The adjustment drive 226 can be a cylinder, linear guide, etc.

[0104] In some embodiments, please refer to Figure 2 and Figure 6The material loading assembly 212 includes multiple suction disks 2122, each with a loading position 2121 and a vacuum hole (not shown) extending to the loading position 2121. The suction disks 2122 are connected to a motion assembly 211, which drives the suction disks 2122 to move along the X-axis. The motion assembly 211 can be a linear guide. The number of suction disks 2122 is consistent with the number of telescopic grippers 2253. The suction disks 2122 are used to carry the film 200 and the workpiece 300. When the film 200 is placed on the suction disk 2122, the suction disk 2122 can also generate negative pressure through the vacuum hole to adsorb the film 200, thereby improving the stability of the film 200.

[0105] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7 The film component 200 includes a lower film 202 and an upper film 201 that are bonded together. It can be understood that when applying the film, the film component 200 needs to be torn apart, and then the workpiece 300 is placed between the lower film 202 and the upper film 201, so that the film is applied to both sides of the workpiece 300. The film-tearing mechanism 23 includes a film-tearing frame 231, a first longitudinal drive member 232, and a plurality of film-tearing grippers 233 connected to the first longitudinal drive member 232. The film-tearing frame 231 is disposed above the motion assembly 211. The first longitudinal drive member 232 is connected to the film-tearing frame 231. The first longitudinal drive member 232 drives the film-tearing grippers 233 to move in the Z-axis direction so that when the suction plate 2122 moves below the film-tearing frame 231, the film-tearing grippers 233 hold the upper film 201. When the suction plate 2122 moves in the opposite direction to the X-axis direction, the film-tearing grippers 233 hold the upper film 201 and move it in the Z-axis direction, thereby tearing the upper film 201 and the lower film 202 of the film component 200 apart.

[0106] The film-tearing frame 231 can be a U-shaped structure, mounted above the motion component 211, with two legs positioned on either side of the motion component 211. The first longitudinal drive component 232 can be a cylinder, linear guide, etc., and the film-tearing gripper 233 can be a structure driven by a cylinder, with the number of film-tearing grippers 233 matching the number of suction trays 2122. Thus, the upper film 201 and lower film 202 in the film component 200 can be torn apart by the film-tearing grippers 233. When tearing the film, the film-tearing grippers 233 only tear one end of the upper film 201 away from the lower film 202, while the other ends of the upper and lower films 201 remain connected. The openings of the upper and lower films 201 face the transfer component 225, facilitating the transfer component 225 to place the workpiece 300 between the lower and upper films 202.

[0107] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7The film-tearing mechanism 23 also includes a rotating assembly 234, which includes a connector 2341, a rotating plate 2342, and a rotating drive 2343. The connector 2341 is connected to the output end of the first longitudinal drive 232. The rotating plate 2342 is rotatably connected to the connector 2341. The film-tearing gripper 233 is connected to the rotating plate 2342. The rotating drive 2343 is connected to the connector 2341, and the output end of the rotating drive 2343 is connected to the rotating plate 2342. The rotating drive 2343 is used to drive the rotating plate 2342 to rotate, thereby driving the film-tearing gripper 233 to rotate. The connector 2341 can be a U-shaped structure, the rotating plate 2342 can be a strip structure, and both ends are rotatably connected to the connector 2341. The rotating plate 2342 can rotate in the XZ plane. The rotating drive 2343 can be a rotary cylinder, etc. The rotating drive 2343 and the rotating plate 2342 can be connected by a belt, chain, etc., so that the rotating drive 2343 can drive the rotating plate 2342 to rotate.

[0108] It is understood that after the film-tearing claw 233 grips the upper film 201, the motion component 211 drives the material-carrying component 212 to move in the opposite direction along the X-axis. The first longitudinal drive component 232 drives the film-tearing claw 233 to move along the Z-axis. At the same time, the rotation drive component 2343 drives the rotating plate 2342 to rotate clockwise in the XZ plane, thereby driving the film-tearing claw 233 to rotate clockwise in the XZ plane. This ensures that the film-tearing claw 233 maintains the flatness of the upper film 201 while moving it, preventing the film-tearing claw 233 from directly moving along the Z-axis and causing creases on the upper film 201, which would affect the flatness during film application. In one embodiment, the rotation angle range of the rotation drive component 2343 driving the rotating plate 2342 to rotate is 30°-60°, preferably 45°.

[0109] In some embodiments, please refer to Figure 2 , Figure 8 and Figure 9 The film-taking mechanism 24 also includes a film holder 241, a second longitudinal drive member 242, a connecting plate 243, multiple rotary drive members 244, and multiple film-taking grippers 245. The film holder 241 is disposed above the motion assembly 211. The film holder 241 is provided with a slot 2411 for carrying the film component 200. The second longitudinal drive member 242 is connected to the film holder 241. The connecting plate 243 is connected to the second longitudinal drive member 242. The rotary drive member 244 is connected to the connecting plate 243. The film-taking grippers 245 are driven to connect with the rotary drive members 244. The second longitudinal drive member 242 is used to drive the connecting plate 243 to move in the Z-axis direction. The rotary drive member 244 is used to drive the film-taking grippers 245 to rotate so that the film-taking grippers 245 can grab the film component 200 from the slot 2411 or place the film component 200 on the suction tray 2122.

[0110] The membrane holder 241 can be a U-shaped structure, with multiple slots 2411 for supporting the membrane component 200. Each slot 2411 has a through hole at its bottom, the area of ​​which is smaller than the area of ​​the membrane component 200. This allows the slots 2411 to support the membrane component 200 while the membrane-retrieving gripper 245 can remove the membrane component 200 through the through hole at the bottom of the slot. The second longitudinal drive component 242 can be a linear guide rail, etc. The connecting plate 243 can be a plate-like structure, providing stable support for the rotary drive component 244, which can be a rotary cylinder, etc. The membrane-retrieving gripper 245 can be a suction cup type gripper, allowing it to remove the membrane component 200 through the through hole at the bottom of the slot 2411.

[0111] In some embodiments, please refer to Figure 2 , Figure 8 and Figure 9 The film pressing mechanism 25 includes a film pressing wheel 251, which is connected to the side of the connecting plate 243 opposite to the film-taking gripper 245. When the suction plate 2122, carrying the workpiece 300 and the film piece 200, moves along the X-axis to below the film-taking gripper 245, the film pressing wheel 251 rolls the film piece 200 and the workpiece 300, thereby adhering the film piece 200 to the workpiece 300. It is understood that the film pressing mechanism 25 also includes necessary mounting brackets, elastic elements (not shown), and other structures. The mounting bracket can be connected to the connecting plate 243 and is used to support the film pressing wheel 251. The elastic element can be disposed between the film pressing wheel 251 and the mounting bracket so that when the film pressing wheel 251 rolls the film piece 200, it can elastically contact the film piece 200, providing a cushioning effect.

[0112] In some embodiments, please refer to Figure 1 , Figure 10 and Figure 11The feeding module 10 includes a tray dispensing assembly 11, a conveying assembly 12, a feeding assembly 13, and a tray receiving assembly 14. The conveying assembly 12 is adjacent to the transfer mechanism 22 and conveys the trays 400 along the Y-axis. The tray dispensing assembly 11 is located at the front end of the conveying assembly 12 along the Y-axis and is used to carry the stacked trays 400 and place individual trays 400 on the conveying assembly 12. The feeding assembly 13 picks up the workpieces 300 from the trays 400 located on the conveying assembly 12 and places the workpieces 300 on the transfer mechanism 22. The tray receiving assembly 14 is located at the end of the conveying assembly 12 along the Y-axis and is used to collect the trays 400 conveyed by the conveying assembly 12. The conveying component 12 can be a conveyor belt, etc. By setting the tray-dispensing component 11, a single tray 400 carrying a workpiece 300 can be placed on the conveying component 12. The conveying component 12 conveys the tray 400 carrying the workpiece 300 along the Y-axis to the loading component 13. The loading component 13 places the workpiece 300 in the tray 400 onto the first positioning component 221 and the second positioning component 222 in the transfer mechanism 22, completing the loading. The conveying component 12 then conveys the empty tray 400 to the receiving component 14, which collects the empty tray 400. In this way, the automatic feeding and collection of trays 400 is completed.

[0113] In some embodiments, please refer to Figure 1 , Figure 10 and Figure 11 The tray distribution assembly 11 includes a tray positioning component 111 and a clamping and lifting component 112. The tray positioning component 111 is fixedly connected to the conveying assembly 12 and is used to position the tray 400. The clamping and lifting component 112 is fixedly connected to the conveying assembly 12 and is correspondingly set to the tray positioning component 111. The clamping and lifting component 112 is used to be inserted between the bottommost and second-to-last trays 400 to lift the other trays 400 except the bottommost tray 400, thereby leaving the bottommost tray 400 on the conveying assembly 12. The conveying assembly 12 then conveys the bottommost tray 400 along the Y-axis direction.

[0114] The tray positioning component 111 can be formed by multiple columnar structures and is used to position the tray 400. Understandably, during use, multiple trays 400 are stacked within the tray positioning component 111. When discharging, the clamping and lifting component 112 drives the multiple trays 400 to move in the Z-axis direction. By setting the tray positioning component 111, the stability of the trays 400 during Z-axis movement is improved while simultaneously positioning them. The clamping and lifting component 112 can be a combination structure of a cylinder driving the clamping fingers. When discharging the tray 400, the clamping fingers of the clamping and lifting component 112 are inserted between the bottommost and second-to-last trays 400, and then the upper trays 400 are lifted along the Z-axis direction, leaving the bottommost tray 400 on the conveying component 12. The conveying component 12 then conveys the bottommost tray 400 along the Y-axis direction. When the tray 400 is placed again, the conveying component 12 stops moving, and the clamping lifting component 112 drives the tray 400 to move in the opposite direction of the Z-axis so that the bottom tray 400 contacts the conveying component 12. Then, the clamping fingers of the clamping lifting component 112 leave the bottom tray 400 and insert between the bottom tray 400 and the second to last tray 400. The above actions can be repeated.

[0115] In some embodiments, please refer to Figure 1 , Figure 10 and Figure 11 The feeding assembly 13 includes a second displacement drive 131, a transfer frame 132, multiple pitch-changing drive components 133, and multiple feeding grippers 134. The second displacement drive 131 is disposed between the conveying assembly 12 and the transfer mechanism 22. The transfer frame 132 is connected to the second displacement drive 131. The pitch-changing drive 133 is connected to the transfer frame 132. The feeding grippers 134 are connected to the pitch-changing drive 133. The second displacement drive 131 drives the transfer frame 132 to move along the X-axis, thereby driving the pitch-changing drive 133 and the feeding grippers 134 to move along the X-axis. The multiple pitch-changing drive components 133 drive the multiple feeding grippers 134 to move closer to each other when picking up material from the material tray 400, and to move further apart when placing material onto the transfer mechanism 22.

[0116] The second displacement drive 131 can be a linear guide rail, etc., the transfer frame 132 can be a portal frame structure, and the loading gripper 134 can be a combination of a cylinder and a suction cup gripper. The number of loading grippers 134 corresponds to the number and position of the workpieces 300 carried in the tray 400, so that the loading grippers 134 can remove all the workpieces 300 from the tray 400 in one go. The variable pitch drive 133 can be a telescopic cylinder, etc. When the loading assembly 13 is picking up materials, the second displacement drive 131 drives the transfer frame 132 to move in the opposite direction of the X-axis. At this time, the variable pitch drive 133 drives multiple loading grippers 134 to move closer to each other until the loading grippers 134 correspond to the workpieces 300 in the tray 400, and then the loading grippers 134 grab the workpieces 300. After the workpiece 300 is gripped, the second displacement drive 131 drives multiple loading grippers 134 to move along the X-axis. At this time, the variable pitch drive 133 drives the multiple loading grippers 134 to move away from each other until they correspond to the first positioning component 221 and the second positioning component 222. Then the workpiece 300 is placed on the positioning unit 223 on the first positioning component 221 and the second positioning component 222.

[0117] In some embodiments, please refer to Figure 1 and Figure 12 The unloading module 30 includes a receiving component 31, a collecting component 32, and an unloading component 33. The receiving component 31 is disposed adjacent to the film taking mechanism 24 along the X-axis direction. The collecting component 32 is disposed adjacent to the receiving component 31 along the X-axis direction. The unloading component 33 is disposed below the collecting component 32. The receiving component 31 grips the workpiece 300 with the film 200 attached to it, which is carried by the loading mechanism 21. The collecting component 32 collects the workpiece 300 gripped by the receiving component 31 and places the workpiece 300 on the unloading component 33. The unloading component 33 is used to convey the workpiece 300 to a picking area.

[0118] The receiving component 31 can be a combination of a cylinder and a suction cup gripper, the collecting component 32 can be a combination of a linear track, a telescopic cylinder, a tray, etc., and the unloading component 33 can be a transmission belt.

[0119] After the motion component 211 drives the suction plate 2122 past the film pressing mechanism 25, the suction plate 2122 stops sucking air. The receiving component 31 removes the workpiece 300 with the film component 200 attached from the suction plate 2122 and moves it upward along the Z-axis. Then, the collecting component 32 moves sequentially under each gripper of the receiving component 31, and the receiving component 31 releases the corresponding workpiece 300 with the film component 200 attached in sequence. The workpieces 300 are stacked in the collecting component 32. After the collecting component 32 collects a sufficient number of workpieces 300, it places the workpieces 300 on the unloading component 33. After the collecting component 32 collects a sufficient number of workpieces 300 again, it places the workpieces 300 next to the position where the stacked workpieces 300 were placed previously along the Y-axis, until the receiving component 31 is full of stacked workpieces 300 along the Y-axis. Then, the unloading component 33 moves multiple workpieces 300 along the X-axis to the edge for manual collection.

[0120] The working process of the film application device 100 provided in this embodiment is roughly as follows:

[0121] First, the operator stacks multiple trays 400 carrying workpieces 300 to be laminated onto the loading module 10, and places them into the tray dispensing assembly 11. The tray dispensing assembly 11 then places a single tray 400 carrying a workpiece 300 onto the conveying assembly 12. The conveying assembly 12 transports the trays 400 along the Y-axis until they correspond to the loading assembly 13, at which point the conveying assembly 12 stops moving. The second displacement drive 131 in the loading assembly 13 drives the transfer frame 132 to move in the opposite direction along the X-axis. At this time, the pitch drive 133 drives multiple loading grippers 134 to move closer to each other until the loading grippers 134 correspond to the workpieces 300 in the trays 400. Then, the loading grippers 134 pick up the workpieces 300. After gripping the workpiece 300, the second displacement drive 131 drives multiple loading grippers 134 to move along the X-axis. At this time, the pitch-changing drive 133 drives the multiple loading grippers 134 to move away from each other until they correspond to the first positioning component 221 and the second positioning component 222. Then, the workpiece 300 is placed on the positioning unit 223 on the first positioning component 221 and the second positioning component 222 of the transfer mechanism 22. The conveying component 12 continues to transport the empty tray 400 along the Y-axis until it reaches the receiving component 14, which collects the empty tray 400.

[0122] After workpiece 300 is placed on the first positioning component 221 and the second positioning component 222, each positioning unit 223 positions the workpiece 300. The misalignment drive 224 drives the first positioning component 221 to move along the Y-axis, causing the workpiece 300 on the first positioning component 221 and the workpiece 300 on the second positioning component 222 to be misaligned. Then, the first displacement drive 2251 in the transfer component 225 drives the transfer frame 2252 to move in the opposite direction along the X-axis, causing the telescopic gripper 2253 to grasp the workpiece 300 on the first positioning component 221 and the second positioning component 222. It can be understood that when the telescopic gripper 2253 grasps the workpiece 300 on the first positioning component 221 and the second positioning component 222, the movable positioning component 2233 in the positioning unit 223 stops holding the workpiece 300, facilitating material removal.

[0123] While the transfer assembly 225 grips the workpiece 300, the motion assembly 211 drives the suction disk 2122 in the loading assembly 212 to move along the X-axis to below the film-taking mechanism 24. The second longitudinal drive 242 in the film-taking mechanism 24 drives the connecting plate 243 and multiple film-taking grippers 245 to move along the Z-axis. Simultaneously, the rotation drive 244 drives the film-taking grippers 245 to rotate towards the slot 2411, thereby removing the film piece 200 from the slot 2411. Then, the second longitudinal drive 242 drives the connecting plate 243 and multiple film-taking grippers 245 to move in the opposite direction along the Z-axis. The rotation drive 244 then drives the film-taking grippers 245 to rotate towards the suction disk 2122, thereby placing the film piece 200 onto the suction disk 2122. The suction disk 2122 adsorbs the film piece 200, and the motion assembly 211 then drives the suction disk 2122, which adsorbs the film piece 200, to move below the film-tearing mechanism 23.

[0124] After the suction plate 2122 moves the film 200 below the film-tearing mechanism 23, the first longitudinal drive member 232 drives the rotating assembly 234 and the film-tearing gripper 233 to move in the opposite direction along the Z-axis until the film-tearing gripper 233 clamps the end of the upper film 201. Then the motion assembly 211 continues to drive the suction plate 2122 to move in the opposite direction along the X-axis. At the same time, the first longitudinal drive member 232 drives the rotating assembly 234 and the film-tearing gripper 233 to move along the Z-axis. The rotating assembly 234 drives the film-tearing gripper 233 to rotate clockwise in the XZ plane to tear the film 200 and make the opening face the transfer assembly 225.

[0125] After the film 200 is torn open, the first displacement drive 2251 in the transfer assembly 225 drives the transfer frame 2252 to move along the X-axis, thereby causing the telescopic gripper 2253 to place the workpiece 300 onto the lower film 202 on the suction plate 2122. Then, the transfer assembly 225 resets, waiting for the next transfer. After the workpiece 300 is placed on the lower film 202, the motion assembly 211 drives the suction plate 2122 to move along the X-axis, the first longitudinal drive 232 drives the film tearing gripper 233 to move in the opposite direction along the Z-axis, and the rotation assembly 234 drives the film tearing gripper 233 to rotate counterclockwise in the XZ plane until the upper film 201 covers the workpiece 300, and the film tearing gripper 233 releases the upper film 201.

[0126] The motion component 211 continues to drive the suction plate 2122 to move along the X-axis and pass under the film pressing mechanism 25. The film pressing roller 251 of the film pressing mechanism 25 rolls the upper film 201 so that the upper film 201 and the lower film 202 are in contact with the workpiece 300. After being rolled by the film pressing roller 251, the motion component 211 moves the suction plate 2122 to the end and aligns it with the unloading module 30. The suction plate 2122 then stops sucking air.

[0127] The receiving component 31 in the unloading module 30 removes the workpiece 300 with the film component 200 attached from the suction plate 2122 and moves it upwards along the Z-axis. Then, the collecting component 32 sequentially collects the workpieces 300 with the film component 200 attached that were picked up by the receiving component 31. The workpieces 300 with the film component 200 attached are stacked in the collecting component 32. When the collecting component 32 has collected a sufficient number of workpieces 300, it places the workpieces 300 on the unloading component 33. When the collecting component 32 has collected a sufficient number of workpieces 300 again, it places the workpieces 300 next to the position where the stacked workpieces 300 were placed previously, along the Y-axis, until the receiving component 31 is full of stacked workpieces 300 along the Y-axis. Then, the unloading component 33 moves multiple workpieces 300 along the X-axis to the edge for manual collection.

[0128] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
