Description

Technical Field

[0001] This application relates to the technical field of automated production equipment, and more particularly to a tank-mounted film applicator. Background Technology

[0002] In many current products, riveting, bolting, or welding are frequently used when assembling components, especially for smaller products. Welding offers advantages such as simple structure, high joint strength, metal saving, high productivity, and low cost. However, prolonged exposure to air can cause oxidation and damage to the weld points, leading to unstable connections and affecting the product's appearance. Therefore, applying a protective film to the weld points not only protects them but also masks the weld seam, improving the product's overall appearance.

[0003] Currently, the application of solder joint protective film is mainly done manually. This process is prone to problems such as missed spots, incomplete application, and damage to the solder joints due to excessive pressure. This is especially true when the solder joints are located inside grooves in the product, making application more difficult. Manual application is challenging, has a low pass rate, increases labor costs, and hinders efforts to reduce production costs. Furthermore, when applying film inside product grooves, manual application is cumbersome, compromising quality, reducing efficiency, and impacting yield. Summary of the Invention

[0004] This application provides a tank-mounted film application device to solve the problem of uneven film application quality caused by manual operation at the weld joints inside the product tank in the prior art.

[0005] This application provides an in-slot film application device for applying protective film to a product in a slot. The in-slot film application device includes a positioning component, a film application component, and a film removal component. The positioning component includes a material platform, a first displacement structure, and a base. The material platform and the base are locked together. The first displacement structure drives the material platform to lock with the base. The material platform is loaded with a composite film, which includes at least a stacked lower film, a protective film, and an upper film. The film application component includes a second transfer structure, a third transfer structure, and a loading structure. When the material platform and the base are locked together, the second transfer structure transfers the composite film onto the loading structure. The film removal component includes a first film removal structure. The composite film is located behind the loading structure. The first film removal structure removes the upper film, and the third transfer structure moves the protective film to adhere it to the product.

[0006] Furthermore, the positioning component also includes a sensing structure that is slidably connected to the base, and the sensing structure can acquire position information of the combined membrane when it is located on the material platform.

[0007] Furthermore, the material platform includes a loading platform and a loading seat. The first displacement structure includes a first push rod, a first cylinder, a first push block, and a first baffle. The first cylinder drives the first push block to slide in a direction close to the first baffle. The first push block and the first baffle clamp the loading seat to complete the locking. The loading platform is fixedly connected to the output end of the first push rod. The first push rod can push the loading platform to slide relative to the loading seat in a first direction.

[0008] Furthermore, the second transfer structure includes a first slider, a first slide rail, a second slider, and a second slide rail. The first slide rail is arranged along a first direction, and the second slide rail is arranged along a second direction. The first slide rail is fixedly connected to the second slider, the first slider is slidably connected to the first slide rail, and the second slider is slidably connected to the second slide rail. A first gripping structure is provided at one end of the first slide rail near the combined film, and the first gripping structure can grip the combined film.

[0009] Furthermore, the loading structure is fixedly connected to the third slider of the third transfer structure, and the third slider is slidably connected to the third slide rail. The sliding direction is the third direction. The loading structure has a second gripping structure at one end facing the second transfer structure. The second gripping structure is used to grip the combined membrane. The third slider has a third gripping structure on the side away from the second transfer structure. After the loading structure moves along the third direction, the third gripping structure grips the lower membrane.

[0010] Furthermore, the protective film is annular, and the second gripping structure is correspondingly annular. The loading structure includes a guide post and a first elastic element. One end of the guide post is connected to the first elastic element, and the other end of the guide post passes through the second gripping structure. The guide post can be slidably disposed relative to the second gripping structure along a first direction, and the first elastic element applies a thrust to the guide post.

[0011] Furthermore, the in-tank film application equipment also includes a first robotic arm, which includes a first clamping structure for the product and a first film-tearing structure fixedly mounted on the first robotic arm. After the first film-tearing structure tears off the upper film, the first clamping structure drives the product to adhere to the protective film.

[0012] Furthermore, the in-tank film application equipment also includes a pressure holding assembly, which includes a loading frame, a fourth displacement structure, and a pressure holding structure. The loading frame can slide along the second direction via the fourth displacement structure. The pressure holding structure and the loading frame have a pressure holding position. When the loading frame is in the pressure holding position, the pressure holding structure continuously applies a constant pressure to the product located between the pressure holding structure and the loading frame.

[0013] Furthermore, the in-tank film application equipment also includes a second robotic arm, which includes a second clamping structure. The film-tearing assembly also includes a second film-tearing structure. The second clamping structure moves the product to the clamping end of the second film-tearing structure, and the clamping end can clamp the lower film on the product.

[0014] Furthermore, the second film-tearing structure includes a gripper and a rotating component. The gripper is fixedly connected to the rotating component, and the rotating component drives the gripper to tear off the lower film by rotating.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] like Figure 1As shown in the figure, this application embodiment provides an in-slot film application device for applying protective film to the in-slot of a product, including: a positioning component 20, a film application component 30, and a film peeling component 40. The positioning component 20 includes a material platform 21, a first displacement structure 22, and a base 23. The material platform 21 and the base 23 are in a locked state. The first displacement structure 22 drives the material platform 21 to lock with the base 23. The material platform 21 is loaded with a composite film 10, which includes at least a lower film 11, a protective film 12, and an upper film 13 stacked together. The film application component 30 includes a second transfer structure 31, a third transfer structure 32, and a loading structure 33. When the material platform 21 and the base 23 are in a locked state, the second transfer structure 31 transfers the composite film 10 onto the loading structure 33. The film peeling component 40 includes a first film peeling structure 41. The composite film 10 is located behind the loading structure 33. The first film peeling structure 41 peels off the upper film 13, and the third transfer structure 32 moves the protective film 12 so that the protective film 12 is adhered to the product 50. The composite film 10 is positioned by locking the material platform 21 and base 23 in the positioning component 20. Then, the composite film 10 and product 50 are transferred to the loading structure 33 by the second transfer structure 31 to complete the bonding. Finally, the remaining film is removed by the film-removing component 40. This allows the entire in-slot film-applying equipment to replace manual film application, ensuring precise positioning, application, and removal of film each time, resulting in uniform film quality. This application effectively solves the problem of uneven film quality caused by manual film application at the welding points of product 50 in the slot in the prior art.

[0039] It should be noted that, as Figure 16 As shown, in the technical solution of this embodiment, the combined film includes a lower film 11, a protective film 12, and an upper film 13. The protective film 12 is specifically an annular film. The product 50 has an installation cavity that matches the protective film 12. Before installation, there are solder joints inside. The protective film 12 cooperates with the installation cavity to cover the solder joints. The lower film 11 has a separate part that protrudes in the width direction of the protective film 12 to facilitate the removal of the lower film 11. The upper film 13 has a tearing position set in the length direction of the protective film 12. It is offset from the lower film 11 and can be clamped to remove the film, so as to avoid the multi-film combination from interfering with each other, which may cause the upper film 13 or the lower film 11 to be unable to be removed, or leave residue after bonding.

[0040] like Figure 2As shown, in this embodiment, the positioning component 20 further includes a sensing structure 24, which is slidably connected to the base 23. The sensing structure 24 can acquire the position information of the combined membrane 10 when it is located on the material table 21. The sensing structure 24 can automatically identify the position of the combined membrane 10, enabling precise positioning during subsequent combined membrane transfer. It should be noted that, because the combined membrane 10 has a small overall thickness and high flexibility, it is prone to deformation during use. Therefore, clamp-type tools cannot be directly selected for the transfer of the combined membrane 10, and deformation of the combined membrane 10 is not conducive to recovery and positioning.

[0041] like Figure 2 and Figure 3 As shown, in this embodiment, the material platform 21 includes a loading platform 211 and a loading seat 212. The first displacement structure 22 includes a first push rod 221, a first cylinder 222, a first push block 223, and a first baffle 224. The first cylinder 222 drives the first push block 223 to slide along a direction close to the first baffle 224. The first push block 223 and the first baffle 224 clamp the loading seat 212 to complete the locking. The loading platform 211 is fixedly connected to the output end of the first push rod 221. The first push rod 221 can push the loading platform 211 to slide relative to the loading seat 212 along the first direction Z. The first cylinder 222 is used to lock and release the specific position of the loading seat 212. The first push rod 221 is used to push the loading platform 211 to a suitable height so that the sensing structure 24 can detect the specific position of the combined membrane 10, and also facilitates the gripping of the combined membrane 10 by the second transfer structure 31.

[0042] It should be noted that the loading seat 212 can be detached from the base 23 for filling the combined membrane 10. Specifically, it can be pulled out directly after the first cylinder 222 pushes the first push block 223 away from the loading seat 212 via a pull rod set on the side wall of the loading seat 212. The loading seat 212 drives the loading table 211 to detach from the entire positioning assembly 20, and then filling is performed. The loading seat 212 is provided with a guide rail, and the loading table 211 is slidably connected to the guide rail. The direction of the guide rail is set along the first direction Z, which is the same as the pushing direction of the first push rod 221. The first push rod 221 and the loading table 211 are not fixedly connected. The sensing structure 24 can be a visual acquisition structure. The sensing structure 24 is fixedly connected to the second cylinder 25, which can drive the sensing structure 24 to move in the first direction Z. This configuration provides a certain sensing range in the first direction Z, compensating for errors caused by long-term use of the loading seat 212 and making positioning more accurate. After completing identification, the sensing structure 24 can move towards the base 23 to avoid interference with the second transfer structure 31 during operation, preventing component collisions. The first push rod 221 is driven by a drive motor 225. Specifically, the first push rod 221 can be a threaded rod, moving through the rotation of the motor.

[0043] like Figure 4 and Figure 5 As shown, in this embodiment, the second transfer structure 31 includes a first slider 311, a first slide rail 312, a second slider 313, and a second slide rail 314. The first slide rail 312 is arranged along a first direction Z, and the second slide rail 314 is arranged along a second direction X. The first slide rail 312 is fixedly connected to the second slider 313, the first slider 311 is slidably connected to the first slide rail 312, and the second slider 313 is slidably connected to the second slide rail 314. A first gripping structure 315 is provided at one end of the first slide rail 312 near the combined film 10, and the first gripping structure 315 can grip the combined film 10. This arrangement provides more precise transfer and ensures better subsequent film application and removal.

[0044] It should be noted that the first gripping structure 315 includes a stop block 3151, a second elastic element 3152, a connector 3153, a suction connector 3154, and a suction structure 3155. The first gripping structure 315 specifically uses a suction method to hold the combined film 10 to prevent the combined film 10 from falling during handling. The stop block 3151 is used to fix the second elastic element 3152. The second elastic element 3152 is fixed between the stop block 3151 and the connector 3153. The second elastic element 3152 is used to provide a certain buffering performance. When picking up the combined film 10, it is necessary to press the combined film 10 tightly. The buffering performance can prevent the combined film 10 from being directly crushed or the upper film 13, lower film 11, and protective film 12 from being pressed too tightly, which would hinder the subsequent film tearing process. The connector 3153 is used to fix the suction connector 3154 and the suction structure 3155. The suction connector 3154 is used to connect the air source and the suction structure 3155. The suction structure 3155 is used to contact the combined membrane 10. The pneumatic method can avoid damage to the combined membrane 10 and improve the utilization rate of raw materials.

[0045] like Figure 6 and Figure 7As shown, in the technical solution of this embodiment, the loading structure 33 is fixedly connected to the third slider 321 of the third transfer structure 32. The third slider 321 is slidably connected to the third slide rail 322, and the sliding direction is the third direction Y. The loading structure 33 is provided with a second gripping structure 331 at one end facing the second transfer structure 31. The second gripping structure 331 is used to grip the combined film 10. The third slider 321 is provided with a third gripping structure 34 on the side away from the second transfer structure 31. After the loading structure 33 moves along the third direction Y, the third gripping structure 34 grips the lower film 11. The second gripping structure 331 is specifically used to grip the lower film 11 of the composite film 10. When the first gripping structure 315 transfers the composite film 10 above the second gripping structure 331, the suction structure 3155 of the first gripping structure 315 reduces the suction force to just be able to adsorb the composite film 10. After the composite film 10 is positioned by the first gripping structure 315 and the second gripping structure 331, the second gripping structure 331 starts to generate suction force to adsorb and fix the composite film 10, so as to facilitate the subsequent film application process. The third gripping structure 34 is used to clamp the protruding part of the lower film 11 after the second gripping structure 331 has completed the adsorption of the combined film 10. Since the overall thickness of the combined film 10 is relatively thin and easily deformed, it will not be completely adsorbed during adsorption. Under the action of external force, the combined film 10 can still be removed from the second gripping structure 331. Before applying the film, the upper film 13 needs to be peeled off to expose the protective film 12. In order to prevent the combined film 10 from being directly taken away by the film peeling component 40 when peeling off the upper film 13, the third gripping structure 34 is set to completely fix the lower film 11. The lower film 11 fixes the protective film 12. The lower film 11 needs to be peeled off in the subsequent process, so even if the lower film 11 is deformed, it will not affect the film application. That is, the third gripping structure 34 can tightly clamp the lower film 11. It should be noted that the loading structure 33 is also provided with a first suction plate 333, which is connected to the second gripping structure 331 and is used to transfer the gas brought by the air source. The third gripping structure 34 specifically includes a first clamp 341 and a third cylinder 342. The third cylinder 342 can drive the upper jaw of the first clamp 341 to slide along the first direction Z. The output end of the third cylinder 342 is fixedly connected to the upper jaw. This arrangement can lift the upper jaw and also drive the upper jaw and lower jaw to lock the combined membrane 10.

[0046] like Figure 6 and Figure 7As shown, in this embodiment, the protective film 12 is annular, and the second gripping structure 331 is correspondingly annular. The loading structure 33 includes a guide post 332 and a first elastic member. One end of the guide post 332 is connected to the first elastic member, and the other end of the guide post 332 passes through the second gripping structure 331. The guide post 332 can be slidably disposed relative to the second gripping structure 331 along the first direction Z. The first elastic member applies a pushing force to the guide post 332. When the protective film 12 is annular, the corresponding second gripping structure 331 is annular. This arrangement ensures that the annular shapes correspond to each other, reliably gripping the protective film 12 and completing the preparation work for film application. The guide post 332 is used to guide the hollow area formed by the annular region of the protective film 12 when the combined film 10 is transferred, so that the protective film 12 falls accurately onto the second gripping structure 331 surrounding the guide post 332. During film application, the product 50 moves above the combined film 10, and the product 50 presses down to tightly bond with the protective film 12 in the combined film 10. Product 50 is a ring-shaped or cylindrical shell, forming a hollow area. The bottom of the hollow area is the bottom of the inner cavity of product 50. When product 50 is pressed down, guide post 332 first guides the hollow area of ​​product 50, so that product 50 wraps around guide post 332 and second gripping structure 331. After guidance is completed, the bottom of the inner cavity of the hollow area pushes against guide post 332 and moves along the first direction Z. The first elastic element acts as a buffer to prevent guide post 332 from completely pressing against the bottom of the product, thus preventing product 50 from being broken and damaged by guide post 332 when external pressure is applied. The first elastic element compresses and stores elastic potential energy and provides a reaction force to guide post 332. After the film is applied, the first elastic element continues to apply a pushing force to guide post 332, resetting guide post 332.

[0047] It should be noted that the loading structure 33 is also equipped with a fourth cylinder 334. The output end of the fourth cylinder 334 is fixedly connected to the guide post 332. This arrangement can control the specific position of the guide post 332, preventing the guide post 332 from over-compressing the first elastic element and causing it to break. When the guide post 332 is at its maximum extension length, the first elastic element applies a pulling force to the guide post 332. At this time, the fourth cylinder 334 pushes the guide post 332 out, which can extend the guide post 332 and achieve the best guiding effect. The use of the first elastic element also includes stretching and contraction, making full use of the deformation capacity of the first elastic element and controlling the deformation range within the two ranges of compression and stretching, which can better protect the first elastic element. The first elastic element can be selected as a telescopic spring.

[0048] like Figure 8 and Figure 9As shown, in the technical solution of this embodiment, the in-slot film application equipment also includes a first robotic arm 60. The first robotic arm 60 includes a first clamping structure 61 for the product 50 and a first film-tearing structure 41 fixedly disposed on the first robotic arm 60. After the first film-tearing structure 41 tears off the upper film 13, the first clamping structure 61 drives the product 50 to adhere to the protective film 12. The first robotic arm 60 can drive the first film-tearing structure 41 to peel off the upper film 13, and then drive the product 50 to adhere to the protective film 12. Specifically, the first film-tearing structure 41 and the first clamping structure 61 are both fixedly connected to the output end of the first robotic arm 60. The first film-tearing structure 41 includes a fifth cylinder 411 and a second clamp 412. The upper and lower jaws of the second clamp 412 can slide in the first direction Z through the fifth cylinder 411, thereby achieving the clamping and releasing states. The first robotic arm 60 also includes a first base 62 and a first power source 63. Two robotic arms are arranged above the first base 62. Both robotic arms can rotate in the horizontal direction, thereby driving the product 50 to move within a certain range. A displacement structure that can slide in the first direction Z is provided between the robotic arm and the first clamping structure 61. Specifically, it can be a cylinder or a ball screw, which can drive the first clamping structure 61 to slide in the first direction Z, thereby achieving contact and pressing with the protective film 12. The first clamping structure 61 also includes a fixed base 611, a buffer structure 612, and a pressure head structure 613. The pressure head structure 613 can hold the product 50. The buffer structure 612 is connected to the first robot arm 60 through the fixed base 611. The buffer structure 612 is used to release force when the product 50 is bonded to the protective film 12, so as to avoid damaging the product or the protective film 12. After bonding, it plays a pre-pressure holding effect to prevent the protective film 12 from falling off the product 50 before the final pressure holding.

[0049] like Figures 10 to 12As shown in the technical solution of this embodiment, the in-slot film-applying equipment also includes a pressure-holding component 70. The pressure-holding component 70 includes a loading frame 71, a fourth displacement structure 72, and a pressure-holding structure 73. The loading frame 71 can slide along the second direction X via the fourth displacement structure 72. The pressure-holding structure 73 and the loading frame 71 have a pressure-holding position. When the loading frame 71 is in the pressure-holding position, the pressure-holding structure 73 continuously applies a constant pressure to the product 50 located between the pressure-holding structure 73 and the loading frame 71. The fourth displacement structure 72 is provided to avoid interference between the first robotic arm 60 and the pressure-holding structure 73, which could cause the product 50 to fall off. After receiving the product, the loading frame 71 is transferred to the pressure-holding head 735 of the pressure-holding structure 73 via the fourth displacement structure 72. The pressure-holding head 735, driven by the sixth cylinder 732, presses the product 50 in the adsorption seat 711 on the loading frame 71, thereby achieving a second pressure holding between the product 50 and the protective film 12. To ensure that the pressure-holding structure 73 provides a suitable pressure, a pressure regulating valve 731 is also provided on the pressure-holding structure 73. The pressure regulating valve 731 is connected to the sixth cylinder 732 to provide pressure along the first direction Z towards the product 50 to the pad 733 and the pressure-holding plate 734. The loading frame 71 includes an adsorption seat 711, a second suction plate 712, and a loading frame 713. The loading frame 713 is slidably connected to the output end of the fourth displacement structure 72. The fourth displacement structure 72 is specifically a motor and a ball screw thread pair. The loading frame 713 positions the adsorption seat 711 and the second suction plate 712 away from the fourth displacement structure 72 to facilitate the straightening of the air pipe. The adsorption seat 711 generates an adsorption force to ensure that the product 50 is accurately positioned after transfer to facilitate subsequent pressure-holding operations.

[0050] like Figure 14 and Figure 15As shown in the technical solution of this embodiment, the in-groove film application equipment further includes a second robotic arm 80, which includes a second clamping structure 81. The film-tearing assembly 40 also includes a second film-tearing structure 42. The second clamping structure 81 moves the product 50 to the clamping end of the second film-tearing structure 42, where the clamping end can hold the lower film 11 on the product 50. The second robotic arm 80 is used to move the product 50 to the second film-tearing structure 42 for removing the lower film 11. The second robotic arm 80 also includes a second base 82 and a second power source 83. Two robotic arms are arranged above the second base 82. Both robotic arms can rotate in the horizontal direction, thereby driving the product 50 to move within a certain range. A displacement structure that can slide along the first direction Z is provided between the robotic arms and the second clamping structure 81. Specifically, it can be a cylinder or a ball screw, which can drive the second clamping structure 81 to slide along the first direction Z. The second clamping structure 81 also includes a ninth cylinder 811, a connecting seat 812 and a suction mechanism 813. The suction mechanism 813 is used to adsorb and fix the product 50 to facilitate transfer. The arrangement of the ninth cylinder 811 and the connecting seat 812 allows the product 50 to be finely adjusted in the first direction Z to cooperate with the second film-tearing structure 42 in the first direction Z.

[0051] like Figure 13 As shown, in this embodiment, the second tearing structure 42 includes a gripper 421 and a rotating component 422. The gripper 421 is fixedly connected to the rotating component 422, and the rotating component 422 drives the gripper 421 to tear off the lower film 11 by rotating. The lower film 11 has a protruding portion along the width direction of the protective film 12. The rotation direction of the rotating component 422 is tangential to the width direction of the protective film 12, which enables the lower film 11 and the protective film 12 to be torn off with minimal tearing amplitude. It should be noted that the second film-tearing structure 42 also includes a sixth cylinder 423, a seventh cylinder 424, an eighth cylinder 425, a support structure 426, and a corresponding waste collection structure 427. The eighth cylinder 425 drives the gripper 421 to rise to the designated position, while the sixth cylinder 423 opens the gripper 421 and clamps the lower film 11. Then, the seventh cylinder 424 drives the rotating component 422 to rotate, thereby rotating the gripper 421 by 180°. The lower film 11 is torn off from the width of the protective film 12. The rotated lower film 11 is located at the opening of the waste collection structure 427. The waste collection structure 427 can generate suction to suck the flexible lower film 11 from the opening and collect it. At the same time, the second robot arm 80 takes the product 50 after film tearing to the inspection agency for inspection. After passing the inspection, the product 50 is placed in the material tray and sent to the next process.

[0052] It should be noted that in the technical solution of this embodiment, in order to improve production efficiency, multiple components can be set to perform the bonding process simultaneously, thereby improving production efficiency. Specifically, the positioning component 20 is provided with two sets of material platforms 21 and a first displacement structure 22, the film-applying component 30 is provided with two sets of second transfer structures 31, third transfer structures 32, loading structures 33 and third gripping structures 34, and the pressure-holding component 70 is provided with two sets of loading frames 71, a fourth displacement structure 72 and a pressure-holding structure 73. Moreover, each gripping structure in this application can grip multiple products simultaneously for film application. This setting greatly improves production efficiency and increases the output of the film-applying process in the same amount of time. In this application, the second transfer structure 31, the first robot arm 60, the second robot arm 80 and the film-removing component 40 are all one unit. The transfer and film-removing processes need to have a sequence, that is, there is a certain time interval between adjacent processed products. That is, the same components do not need to operate synchronously. This can reduce the precision requirements of equipment assembly and operation, and ensure the efficiency of transfer and film removal. This application does not limit the specific number of the above-mentioned components, but is only one specific implementation method.

[0053] In the technical solution of this embodiment, the specific operation process of the in-tank film application equipment is as follows:

[0054] After the second cylinder 25 drives the sensing structure 24 to rise a certain distance, the loading seat 212 is placed on the base 23, and the first cylinder 222 in the first displacement structure 22 is driven to reset. The first baffle 224 cooperates with the first push block 223 to fix the material platform 21 in the first displacement structure 22. The second cylinder 25 drives the sensing structure 24 to reset, changing the height distance of the combined membrane 10 and cooperating with the first sensing structure 24. At this time, the drive motor 225 drives the first push rod 221 to rise. The first push rod 221 is specifically a lead screw. The first push rod 221 pushes the loading platform 211 in the receiving platform 21 and pushes the combined membrane 10 to the sensing structure 24. The second transfer structure 31 moves the first gripping structure 315 above the positioning component 20 and makes its suction structure 3155 contact the combined membrane 10, sucking the combined membrane 10 upward. Specifically, the air pressure system sucks through the suction connector 3154. Air, specifically the suction connector 3154, sucks up the combined membrane 10. Then, through the movement of the second transfer structure 31, the combined membrane 10 is moved above the third transfer structure 32. At the same time, the fourth cylinder 334 operates to lift the guide column 332. The combined membrane 10 is positioned by the pin on the loading structure 33 and placed at the second gripping structure 331 inside the loading structure 33. At this time, the suction structure 3155 no longer sucks up the combined membrane 10, and the second transfer structure 31 resets. Simultaneously, the air pressure system sucks up air through the first suction plate 333, causing the second gripping structure 331 to suck up the lower membrane 11 in the combined membrane 10. The third cylinder 342 operates to open the first clamp 341. The third slider 321 and the third slide rail 322 work together to move the loading structure a certain distance. At this time, the third cylinder 342 resets, so that the first clamp 341 can just clamp the protruding part of the lower membrane 11 in the combined membrane 10.

[0055] The first robotic arm 60 grips the product 50 via a pressure head structure 613, which has an air source interface. A buffer structure 612 can be connected to a fixed base 611 along the first direction Z. During the movement of the first robotic arm 60, the fifth cylinder 411 of the first film-tearing structure 41 operates to open the second clamp 412. When it reaches above the loading structure 33, the fifth cylinder 411 resets, allowing the second clamp 412 to grip the upper film 13 of the combined film 10. At this time, the first robotic arm 60 moves, causing the second clamp 412 to tear off the upper film 13 and place it into the first waste bin 35. The first robotic arm 60 then moves the first clamping structure 61 directly above the second gripping structure 331 of the loading structure 33. The first clamping structure 61 then moves downwards, causing the inner groove weld point of the product 50 to contact the protective film 12. The guide post 332 acts as a guide, and the lower spring acts as a buffer, pre-pressing the protective film 12 against the product 50. At this time, the lower film 11 bends. At this point, the pre-pressed product 50 is moved to the pressure-holding assembly 70, and the pre-pressed product 50 is placed on the protrusion of the adsorption seat 711. The pneumatic system then generates suction on the second suction plate 712, causing the adsorption seat 711 to hold the product 50 in place, preventing deflection during pressure holding and thus preventing damage to the product 50. The material handling and bonding device positioning assembly 20 and the film-applying assembly 30 then reset. The fourth displacement structure 72 moves the loading frame 71 below the pressure-holding structure 73, and the pressure is adjusted... Valve 731 is adjusted to a suitable pressure, and the sixth cylinder 732 drives the pressure-holding head 735 to descend, so that it contacts the top of the product 50 and then presses it down, so that the protective film 12 and the welding point in the groove of the product 50 are pressed together at a specified time and pressure. At this time, the protective film 12 fits more closely in the inner groove of the product 50, and the lower film 11 will also be more curved, making it easier to peel off the film. The sixth cylinder 732 resets the pressure-holding structure 73, and the fourth displacement structure 72 drives the loading frame 71 to move a certain distance.

[0056] The second robotic arm 80 moves the second clamping structure 81 above the loading rack 71 and contacts the pressure-held product 50. The second clamping structure 81 then holds the pressure-held product 50. Subsequently, the second robotic arm 80 moves the pressure-held product 50 above the second film-tearing structure 42. The eighth cylinder 425 drives the gripper 421 to rise a specified distance, while the sixth cylinder 423 opens the gripper 421. At this point, the bent lower film 11 protruding part of the pressure-held product 50 is exactly in the middle of the gripper 421. Meanwhile, the sixth cylinder 423 causes the gripper 421 to clamp the lower film 11, and then the seventh cylinder 424 drives the rotating component 422 to rotate. The gripper 421 connected to the rotating component 422 also rotates, that is, the gripper 421 rotates 180° to tear off the lower film 11. The sixth cylinder 423 releases the lower film 11 into the waste collection structure 427, where the waste is sucked away by the external cleaning device. At the same time, the second robotic arm 80 inspects the product 50 after tearing the film and puts it into the material tray, thus completing the mechanism.
