Description

Technical Field

[0001] This application relates to the field of film-tearing equipment technology, and more specifically, to a film-raising device, a film-raising method of the film-raising device, and a film-tearing device. Background Technology

[0002] With the advancement of technology in the display panel industry, the requirements for the surface quality of panel glass are becoming increasingly stringent. The surface quality of panel glass is mainly affected by scratches and wear during the manufacturing process. Therefore, to protect the surface quality of the panel glass, a protective film is applied to the surface during production. However, due to production requirements, the protective film needs to be removed during cutting. Therefore, the protective film must be separated before the cutting process.

[0003] Currently, the removal of protective film from glass panels typically involves manual removal, robotic arm operation, or the use of adhesive rollers. However, manual removal is inefficient and may damage the glass due to human error, affecting product quality. Using adhesive rollers for removal leaves the protective film stuck to the rollers, requiring manual or additional equipment for removal or cleaning, increasing production costs and reducing efficiency. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of this application is that existing film-peeling equipment will take away the protective film during the film-peeling process, which requires the addition of equipment to clean the protective film, thereby increasing production costs and maintenance time and reducing work efficiency.

[0011] The film pressing assembly is mounted on the side plate and is used to press the protective film onto the upper surface of the product.

[0012] Furthermore, the film-forming mechanism also includes a tensioning component, which is slidably mounted on the side plate and disposed close to the unwinding component, for adjusting the tension of the adhesive during unwinding and rewinding.

[0013] The tensioning assembly includes a mounting side plate, a tensioning wheel, and a sensing element;

[0014] The mounting side plate is slidably mounted on the side plate, and the tensioning wheel is mounted on the mounting side plate;

[0030] To address the aforementioned technical problems, this application also provides a film-forming method for a film-forming device, employing the following technical solution:

[0031] A film-forming method for a film-forming device, the film-forming method being applied to the aforementioned film-forming device, comprising the following steps:

[0032] Start the lifting mechanism to drive the film-lifting mechanism to descend. The film-lifting assembly contacts the product surface, so that the lower surface of the adhesive part contacts the upper surface of the protective film. The film-pressing assembly presses the protective film onto the upper surface of the product. Then, stop the lifting mechanism.

[0033] Start the lifting mechanism to drive the film lifting mechanism to rise. The film lifting component detaches from the product surface, causing the adhesive to move part of the protective film upward, thus detaching part of the protective film from the product surface. The film pressing component keeps pressing the protective film. Stop the lifting mechanism.

[0034] The pressing assembly continuously presses against the upper surface of the product, controls the winding assembly to start, and drives the adhesive part to move towards the winding assembly, thereby separating the lower surface of the adhesive part from the upper surface of the protective film, and completing the lifting of the protective film from the product.

[0040] Control the film peeling auxiliary mechanism to insert between the protective film and the product.

[0041] To further address the aforementioned technical problems, this application also provides a film-peeling device, which employs the following technical solution:

[0043] The rotating platform device includes a rotating drive mechanism and a rotating platform.

[0044] The film-tearing device is located outside the rotating platform device and at the film-tearing station of the rotating platform device;

[0045] The film-forming device is located outside the rotating platform device and at the film-forming station of the rotating platform device;

[0046] The rotating platform device drives the product through the film-lifting station and the film-tearing station in sequence to complete the film-tearing process of the product's protective film.

[0047] Compared with the prior art, the embodiments of this application have the following main advantages:

[0048] (1) The film-lifting device provided in this application embodiment utilizes a lifting mechanism to drive the entire film-lifting mechanism downwards, thereby controlling the adhesive to descend to the product surface and adhere to the protective film on the product surface. Subsequently, by controlling the lifting mechanism to rise, the initial film-lifting action of the protective film can be completed. The film-lifting mechanism in this application embodiment includes a film-lifting component for controlling the lifting and lowering of the adhesive and a winding mechanism for driving the adhesive to retract and move. By controlling the lifting of the adhesive through the film-lifting component, the protective film can be further detached from the product surface, and the portion of the protective film detached from the product surface is increased to facilitate the subsequent film-tearing process. By driving the movement of the adhesive through the winding mechanism, the adhesive is separated from the protective film after film lifting. The adhesive components are recycled, thereby increasing their utilization rate. The film-lifting mechanism also includes a film-pressing assembly. Through the pressing action of the film-pressing assembly, the protective film is ensured to only partially detach from the product surface during the film-lifting process, rather than completely detaching from the product surface. This prevents the adhesive components from taking away the protective film during recycling, which would reduce the utilization rate of the adhesive components. In addition, the film-pressing assembly partially presses the protective film onto the product surface to prevent surface damage during subsequent product transfer. The film-lifting device provided in this application embodiment can utilize the adhesive components to complete the film-lifting action of the protective film, while also improving the utilization rate of the adhesive components, increasing work efficiency, and reducing production costs.

[0049] (2) The film-lifting method of the film-lifting device provided in this application uses a lifting mechanism to drive the film-lifting mechanism to descend, so that the adhesive and the pressing assembly respectively contact the upper surface of the protective film. Then, the lifting mechanism is controlled to drive the film-lifting mechanism to rise, so that the adhesive pulls part of the protective film off the upper surface of the product, and the pressing assembly keeps pressing the protective film to ensure that the protective film will not completely detach from the surface of the product during the film-lifting process, and to prevent the product surface from being damaged when the product is transferred due to the loss of the protective film. After the protective film is lifted, the adhesive is driven to move by the winding assembly to detach from the protective film, and the adhesive is recycled in the winding assembly, so that the adhesive can be reused, improving the utilization rate of the adhesive and reducing the use cost of the adhesive.

[0050] (3) The film-peeling equipment provided in this application separates the film-raising process from the film-peeling process. The protective film of the product is raised in the film-raising device and then peeled off the surface of the product in the film-peeling device. The film-raising device controls the displacement of the film-raising mechanism relative to the product through a lifting mechanism, thereby adapting to products of different thicknesses. After the protective film is raised by the adhesive component, the adhesive component is separated from the protective film, which increases the utilization rate of the adhesive component and reduces the cost of using the adhesive component. After the protective film is raised, the product is transferred to the film-peeling station by a rotating platform mechanism for film peeling. The film-peeling equipment provided in this application separates the film-raising process from the film-peeling process, has wide applicability, high adaptability to products, and can improve the customization of the equipment.

[0068] Embodiments of the film-forming device of this application

[0069] Please see Figure 1 As shown, the film-forming device provided in this application embodiment includes a base 1, a lifting mechanism 2, at least one film-forming mechanism 3, and an adhesive component 4;

[0070] The lifting mechanism 2 is mounted on the base 1.

[0071] The film-forming mechanism 3 is mounted on the lifting mechanism 2. The lifting mechanism 2 is used to drive the film-forming mechanism 3 to rise and fall. In this embodiment, there are two film-forming mechanisms 3. The two film-forming mechanisms 3 have the same structure and are mounted on the lifting mechanism 2 in a mirror image.

[0072] Please see Figure 4 As shown, the film-forming mechanism 3 includes a side plate 31, an unwinding assembly 32, at least one film-forming assembly 33, a film-pressing assembly 34, and a winding assembly 35. In this embodiment, there are two film-forming assemblies 33, which are mirror images mounted on the side plate 31.

[0073] The side plate 31 is mounted on the lifting mechanism 2. The unwinding assembly 32, the film lifting assembly 33, and the winding assembly 35 are mounted on the side plate 31. The adhesive 4 is unwound from the unwinding assembly 32, passes through the film lifting assembly 33, and is wound up at the winding assembly 35. The film lifting assembly 33 is used to push the adhesive 4 to move towards the upper surface of the product so as to bond with the protective film attached to the surface of the product.

[0074] The film pressing assembly 34 is mounted on the side plate 31 and is used to press the protective film onto the upper surface of the product.

[0075] In this embodiment, the lifting mechanism 2 cooperates with the film-lifting assembly 33 to achieve the adhesion of the adhesive 4 to the protective film applied to the product surface and the lifting of the protective film; through the cooperation of the unwinding assembly 32 and the winding assembly 35, the adhesive 4 is kept taut and tightly attached to the film-lifting assembly 33, which is used to push the adhesive 4 to move towards the upper surface of the product to adhere the protective film on the product surface; the film-lifting assembly 33 cooperates with the lifting mechanism 2 to separate at least part of the protective film applied to the product surface from the upper surface of the product.

[0076] The film pressing assembly 34 is mounted on the side plate 31. The film pressing assembly 34 is used to ensure that at least part of the protective film applied to the surface of the product is bonded to the upper surface of the product. In this embodiment, during the film removal process, the film pressing assembly 34 is always pressed against the upper surface of the product to ensure that at least part of the protective film applied to the surface of the product remains bonded to the upper surface of the product.

[0077] In this embodiment, the adhesive 4 is an adhesive tape, which is rolled up and mounted on the unwinding assembly 32. The tape is unwound from the unwinding assembly 32, passes through the film-forming assembly 33, and is wound up at the winding assembly 35. With the cooperation of the unwinding of the unwinding assembly 32 and the winding of the winding assembly 35, the tape is always kept taut and tightly attached to the film-forming assembly 33. The side of the tape facing away from the film-forming assembly 33 is the adhesive surface, which is used to adhere the protective film of the product.

[0078] The film-lifting component 33 is used to push the tape toward the upper surface of the product so that the adhesive surface of the tape adheres to the protective film on the product surface. Then, the lifting mechanism 2 drives the film-lifting mechanism 3 to rise as a whole so that the tape pulls the protective film to separate at least partially from the product surface, thereby realizing the film-lifting of the product's protective film.

[0079] In this embodiment, after the protective film is lifted from the product, the unwinding assembly 32 and the winding assembly 35 are activated to move the adhesive tape toward the winding assembly 35. The adhesive tape further separates the adhered protective film from the product surface. Since the pressing assembly 34 is always pressed against the upper surface of the product, when the separation point of the protective film from the product surface approaches the pressing assembly 34, the protective film separates from the adhesive surface of the adhesive tape due to the pressing action of the pressing assembly 34. This ensures that the protective film only partially detaches from the product surface during the lifting process, rather than completely detaching from the product surface. This prevents the adhesive tape from taking away the protective film during the recycling process of the winding assembly 35, thereby improving the recycling rate of the adhesive.

[0080] Please see Figure 2 , Figure 3 As shown, in this embodiment, the lifting mechanism 2 includes a power source 21, a sliding bracket 22, and a fixed crossbeam 23. The power source 21 is mounted on the base 1, the sliding bracket 22 is movably mounted on the power source 21, and the fixed crossbeam 23 is mounted on the sliding bracket 22. In this embodiment, the two film-lifting mechanisms 3 are mounted side by side and mirror image on the fixed crossbeam 23. The power source 21 is used to drive the sliding bracket 22 to rise and fall along the base 1, thereby driving the film-lifting mechanism 3 to rise and fall. In this embodiment, the power source 21 is a linear motor module.

[0081] Please see Figure 2 As shown, the base 1 is also provided with a lifting detection component 11, which is used to detect the lifting of the sliding bracket 22 on the base 1. In this embodiment, the lifting detection component 11 includes an upper photoelectric switch and a lower photoelectric switch. The upper photoelectric switch and the lower photoelectric switch are installed on the base 1 and are arranged vertically on the same vertical plane, respectively, to limit the upper and lower limits of the displacement of the sliding bracket 22.

[0082] The film-lifting device of this application drives the film-lifting mechanism 3 to rise and fall through the lifting mechanism 2 mounted on the base 1, thereby controlling the movement of the adhesive component 4 relative to the surface of the product. This allows the adhesive component 4 to descend to the surface of the product and adhere to the protective film. Subsequently, the adhesive component 4 rises, lifting the protective film from the product surface. Then, through the cooperation between the film-lifting assembly 33, the unwinding assembly 32, and the winding assembly 35, the adhesive component is controlled to move towards the winding assembly 35, further separating the protective film from the surface of the product, thus completing the film-lifting action. Subsequently, through the unwinding of the unwinding assembly 32, the winding of the winding assembly 35, and the pressing of the protective film by the film-pressing assembly 34, the separation of the adhesive component 4 from the protective film and the recycling of the adhesive component are achieved. This ensures that the protective film only partially detaches from the product surface during the film-lifting process, rather than completely detaching from the product surface, to prevent the adhesive component 4 from taking away the protective film during recycling, thereby improving the utilization rate of the adhesive component 4. In addition, the film-pressing assembly 34 partially presses the protective film onto the product surface to prevent surface damage during subsequent product transfer.

[0083] Please see Figure 5 As shown, the unwinding assembly 32 includes a fixing plate 321, an unwinding bracket 322, a return spring 323, an unwinding drive 324, and an unwinding roll 325. In this embodiment, the unwinding drive 324 is a rotary motor.

[0084] In this embodiment, the fixing plate 321 is movably mounted on the side plate 31 through the cooperation of a fixing member (such as a fixing screw) and a slot. The unwinding bracket 322 is movably mounted on the fixing plate 321 through a guide rod. The unwinding drive 324 is mounted on the unwinding bracket 322. The unwinding roll 325 is fitted onto the output end of the unwinding drive 324. The reset spring 323 is fitted onto the guide rod and clamped between the unwinding bracket 322 and the fixing plate 321.

[0085] In this embodiment, the film-forming assembly 33 adjusts the tension of the unwinding end of the adhesive component 4 by adjusting the fit between the fixing member and the slot, ensuring that the adhesive component 4 will not stick due to insufficient tension. In addition, the tension of the adhesive component 4 in the unwinding section is further adjusted by the reset action of the reset spring 323, thereby ensuring that the adhesive component 4 is fully unfolded in the unwinding section.

[0086] The winding assembly 35 includes a winding drive 351, a transmission belt 352, and a take-up roll 353. In this embodiment, the winding drive 351 is a rotary motor. The output end of the winding drive 351 is connected to a drive pulley, and the take-up roll 353 is connected to a driven pulley. The drive pulley and the driven pulley are connected by the transmission belt 352.

[0087] Please refer to Figure 4. The film-forming mechanism 3 also includes a tensioning component 36. The tensioning component 36 is slidably mounted on the side plate 31 and is located near the unwinding position of the unwinding component 32. It is used to adjust the tension of the adhesive 4 during unwinding and winding. In this embodiment, the adhesive 4 is released from the unwinding component 32, passes through the tensioning component 36 and the film-forming component 34 in sequence, and is then retracted by the winding component 35. The tensioning component 36 is used to adjust the tension of the adhesive 4 during the unwinding and winding process.

[0088] The tensioning assembly 36 includes a mounting side plate 361, a tensioning wheel 362, and a sensing element 363. The mounting side plate 361 is slidably mounted on the side plate 31 by means of a fixing screw and a slot. The tensioning wheel 362 is mounted on the mounting side plate 361. In this embodiment, the operator adjusts the position of the tensioning wheel 362 by adjusting the relative position of the mounting side plate 361 and the side plate 31 along the slot, thereby adjusting the tension of the adhesive part 4. The mounting side plate 361 is fixed by means of a fixing screw and a slot, preventing displacement of the mounting side plate 361 relative to the side plate 31, thus preventing changes in the tension of the adhesive part 4 during operation.

[0089] The sensor 363 is mounted on the mounting side plate 361. In this embodiment, the sensor 363 is a photoelectric sensor. The sensor 363 is used to detect the adhesive 4 so that when the adhesive 4 is exhausted, the staff can immediately know and replace the roll of adhesive 4 in time.

[0090] The application embodiment adjusts the overall tension of the adhesive 4 during winding and unwinding by the tensioning component 36 to ensure that it will not stick due to insufficient tension. The output status of the adhesive 4 is detected by the sensor 363 so that the staff can obtain the output status of the adhesive 4 roll in a timely manner, and can replace the roll in time to ensure continuous output of the adhesive 4.

[0091] Please see Figure 4 , Figure 7 , Figure 8 As shown, the film-forming mechanism 3 also includes a mounting member 37, which is mounted on the side plate 31. The film-forming assembly 33 and the film-pressing assembly 34 are mounted side by side on the lower surface of the mounting member 37. In this embodiment, there are two film-forming assemblies 33, which are mounted side by side on the lower surface of the mounting member 37.

[0092] Please see Figure 7 As shown, the film-forming assembly 33 includes a lifting drive 331, a first elastic element 332, and a film-forming element 333.

[0093] The lifting drive component 331 is mounted on the mounting component 37. The film-raising component 333 includes a connector 3331, a guide rod 3332, and a film-raising pressure head 3333. The connector 3331 is connected to the output end of the lifting drive component 331. One end of the guide rod 3332 is connected to the connector 3331, and the other end is connected to the film-raising pressure head 3333. The first elastic element 332 is fitted onto the output end of the lifting drive component 331 and clamped between the mounting component 37 and the connector 3331 to increase the downward pressure of the film-raising component 333. In this embodiment, the lifting drive component 331 is a cylinder, and the first elastic element 332 is a spring. The spring is fitted onto the piston rod of the cylinder and clamped between the mounting component 37 and the connector 3331.

[0094] The adhesive component 4 is unwound from the unwinding assembly 32, passes through the film-forming pressure head 3333 of the film-forming assembly 33, and is then wound up at the winding assembly 35. In this embodiment, a buffer is also provided on the side of the film-forming pressure head 3333 that contacts the adhesive component 4 to prevent the film-forming pressure head 3333 from damaging the adhesive component 4.

[0095] In this embodiment, the film-forming assembly 33 further includes a guide member 334, which is mounted on the side plate 31. The guide member 334 has a guide hole. One end of the guide rod 3332 is connected to the connector 3331, and the other end passes through the guide hole and is connected to the film-forming pressure head 3333.

[0096] In this embodiment, the side wall of the connector 3331 is provided with a support arm, and an auxiliary sliding member 335 is also provided between the guide member 334 and the support arm. The auxiliary sliding member 335 may be a slider mounted on the support arm and a slide rail mounted on the guide member 334, or a slide rail mounted on the support arm and a slider mounted on the guide member 334.

[0097] In this embodiment, the guide rod 3332 and the guide hole cooperate with the auxiliary sliding member 335 to guide and lift the film-forming assembly 33, thereby improving the film-forming accuracy of the film-forming assembly 33.

[0098] In this embodiment, the film-lifting member 333 is controlled to descend or ascend by the lifting drive member 331, thereby pushing the adhesive member 4 to rise or fall relative to the product surface. When the lifting drive member 331 drives the film-lifting member 333 to descend, the adhesive member 4 moves towards the side closer to the product surface under the drive of the film-lifting pressure head 3333 until it contacts the protective film surface. By providing a first elastic member 332 between the mounting member 37 and the connecting member 3331, the downward pressure of the film-lifting member 3333 is increased, so that the adhesive member 4 can be in close contact with the protective film. This ensures that the adhesive member 4 will not easily separate from the protective film during the ascent, thus ensuring that the protective film can detach from the product surface and complete the film-lifting action.

[0099] Please see Figure 8 As shown, the pressure film assembly 34 includes a second elastic element 341 and a pressure film element 342. The pressure film element 342 includes a connecting rod 3421 and an auxiliary pressure head 3422. The connecting rod 3421 is movably mounted on the side plate 31 through a bearing seat 343. One end of the connecting rod 3421 extends upward through the mounting member 37, and the other end passes through the bearing seat 343 and is connected to the auxiliary pressure head 3422.

[0100] The pressing component 342 also includes a fastener 3423, which is mounted on the connecting rod 3421 by a mounting component. In this embodiment, the fastener 3423 is fixed on the connecting rod 3421 by a set screw and is disposed between the mounting component 37 and the bearing seat 343.

[0101] The second elastic element 341 is fitted onto the connecting rod 3421 and clamped between the mounting member 37 and the fastener 3423. In this embodiment, the second elastic element 341 is a spring.

[0102] The fastener 3423, the second elastic member 341, and the mounting member 37 cooperate to press the film onto the surface of the product, ensuring that the protective film covering the product surface is at least partially bonded to the upper surface of the product.

[0103] In this embodiment, the auxiliary pressure head 3422 is also provided with a buffer on the side close to the product to prevent the auxiliary pressure head 3422 from damaging the protective film when the film pressing component is pressed onto the product surface.

[0104] The film-pressing assembly 34 provided in this embodiment is installed below the mounting member 37. When the lifting mechanism 2 controls the film-lifting mechanism 3 to descend, the mounting member 37 presses down on the second elastic member 341. The second elastic member 341 pushes the fastener 3423 downward, thereby causing the film-pressing member 342 to move downward along the bearing seat 343 and press against the surface of the product. The pressure 341 exerted by the mounting member 37 on the second elastic member increases the pressure of the film-pressing member 342 on the product surface, thereby ensuring that when the protective film is lifted, part of the protective film can always stick to the product surface. When the lifting mechanism 2 controls the film-lifting mechanism 3 to rise, the bearing seat 343 abuts against the fastener 3423, thereby pushing the fastener 3423 upward, thereby causing the film-pressing member 342 to return to its original position and separate from the product surface, so that the product that has completed the protective film lifting action can be transferred to the next process.

[0105] Please see Figure 1 , Figure 6As shown, the film-removing device also includes a film-peeling auxiliary mechanism 5, which is slidably installed at the bottom of the film-removing mechanism 3. After the film-removing mechanism 3 completes the removal of the protective film, it is inserted between the product and the protective film to assist in the removal of the protective film attached to the product surface.

[0106] In this embodiment, the film-peeling auxiliary mechanism 5 is disposed between the film-raising mechanism 3 and the product surface. The film-peeling auxiliary mechanism 5 includes a telescopic drive member 51, a slide table 52, and at least one film-blocking member 53. The slide table 52 is mounted on the output end of the telescopic drive member 51. The film-blocking member 53 is slidably mounted on the slide table 52. In this embodiment, the film-peeling auxiliary mechanism 5 provides two film-blocking members 53 corresponding to each material loading platform.

[0107] Please see Figure 6 As shown, in this embodiment, the film-blocking member 53 is a wedge-shaped block, the width of the film-blocking member 53 near the product end is smaller than the width of the end away from the product, and the cross-section of the film-blocking member 53 is conical or triangular.

[0108] In this embodiment, a film peeling auxiliary mechanism 5 is provided between the film peeling mechanism 3 and the product. After the film peeling mechanism 3 completes the peeling of the protective film, it is inserted between the protective film and the product to support the protective film that has detached from the adhesive 4 and prevent the protective film from falling back onto the product surface under the action of gravity and being re-adheded to the product surface. In addition, the wedge-shaped block of the film blocking member 53 is designed to facilitate insertion between the protective film and the product and assist in peeling the protective film.

[0109] Embodiments of the film-forming method of the film-forming device of this application

[0110] Please see Figure 9 As shown, this application provides a film-forming method for a film-forming device. The film-forming method is applied to the film-forming device and specifically includes the following steps:

[0111] Step S10: Control the lifting mechanism to start, drive the film-lifting mechanism to descend, the film-lifting component to contact the product surface, so that the lower surface of the adhesive part contacts the upper surface of the protective film, the film-pressing component presses the protective film onto the upper surface of the product, and control the lifting mechanism to stop.

[0112] In this embodiment, the mounting member presses the second elastic member downward, and the second elastic member exerts a downward force on the fastener so that the pressure film assembly can be pressed onto the upper surface of the product.

[0113] Step S20: Control the lifting mechanism to start, drive the film lifting mechanism to rise, the film lifting component detaches from the product surface, causing the adhesive to move the protective film upward, causing part of the protective film to detach from the product surface, the film pressing component keeps pressing the protective film, and control the lifting mechanism to stop.

[0114] In this embodiment, the mounting component rises under the action of the film-forming mechanism, but still maintains the compression on the second elastic element. The second elastic element maintains a downward force on the fastener, so that the film-pressing assembly can continuously press against the upper surface of the product, so that part of the protective film remains adhered to the product surface.

[0115] In step S30, the pressing assembly continuously presses against the upper surface of the product, and the winding assembly is started to drive the adhesive part to move towards the winding assembly, thereby separating the lower surface of the adhesive part from the upper surface of the protective film, thus completing the protective film removal of the product.

[0116] In this embodiment, the unwinding and rewinding components are activated to move the adhesive tape toward the rewinding component. The adhesive tape further separates the bonded protective film from the product surface. Since the film pressing component is always pressed against the upper surface of the product, when the separation point of the protective film from the product surface approaches the film pressing component, the protective film separates from the adhesive surface of the adhesive tape due to the pressing effect of the film pressing component. This ensures that the protective film only partially detaches from the product surface during the film-lifting process, rather than completely detaching from the product surface. This prevents the adhesive tape from taking away the protective film during the recycling process of the rewinding component, thereby improving the recycling rate of the bonded parts.

[0117] In step S40, the lifting mechanism is activated, driving the film-lifting mechanism to rise further, which in turn lifts the film-pressing assembly, separating it from the upper surface of the protective film.

[0118] Step S50: Drive the product with the protective film removed to the next process.

[0119] In this embodiment, step S30 controls the winding assembly to start, driving the adhesive component to move towards the winding assembly, thereby separating the lower surface of the adhesive component from the upper surface of the protective film. After the protective film is lifted from the product, the following steps are also included:

[0120] Control the film-lifting assembly to rise, which in turn drives the adhesive component to rise, allowing part of the protective film to completely separate from the product surface.

[0121] Control the film peeling auxiliary mechanism to insert between the protective film and the product.

[0122] In this embodiment, a lifting mechanism drives the film-lifting mechanism to descend, allowing the adhesive and the pressing assembly to contact the upper surface of the protective film. The lifting mechanism then drives the film-lifting mechanism to rise, causing the adhesive to partially detach the protective film from the product's upper surface. The pressing assembly maintains pressure on the protective film, ensuring it doesn't completely detach from the product's surface during the film-lifting process. This prevents damage to the product surface during station transfer due to the loss of the protective film. After film lifting is complete, a winding assembly drives the adhesive to move, detaching it from the protective film. The adhesive is then recycled within the winding assembly, allowing for reuse and increasing its utilization rate while reducing its cost.

[0123] Embodiments of the film-peeling device of this application

[0124] Please see Figure 10 , Figure 11 As shown in the figure, this application provides a film-tearing device, including a rotating platform device 100, a film-lifting device 200, and a film-tearing device 300.

[0125] The rotating platform device 100 includes a rotating drive mechanism 101 and a rotating platform 102. The rotating platform 102 is connected to the output end of the rotating drive mechanism 101. At least one set of material carriers is arranged on the upper surface of the rotating platform 102 along the circumferential direction. In this embodiment, four sets of material carriers are equidistantly arranged on the rotating platform 102 along the circumferential direction. Each set of material carriers includes two material carriers. The position of each material carrier corresponds to the position of the film-forming mechanism.

[0126] The film-forming device 200 is disposed on the outside of the rotating platform device 100 and is located at the film-forming station of the rotating platform device 100;

[0127] The film-tearing device 300 is disposed on the outside of the rotating platform device 100 and is located at the film-tearing station of the rotating platform device 100;

[0128] The rotating platform device 100 drives the product to pass through the film-lifting station and the film-tearing station in sequence to complete the film-tearing process of the product's protective film.

[0129] In this embodiment, a recycling device 400 is also included. The recycling device 400 is arranged in parallel with the film-tearing device 300 and is used to recycle the protective film torn off the product surface by the film-tearing device 300.

[0130] This application separates the film-lifting process from the film-tearing process. The protective film is lifted in a film-lifting device, and then peeled off from the product surface in a film-tearing device. The film-lifting device controls the displacement of the film-lifting mechanism relative to the product through a lifting mechanism, thereby accommodating products of different thicknesses. After the protective film is lifted by the adhesive component, the adhesive component separates from the protective film, increasing the utilization rate of the adhesive component and reducing its usage cost. The product after the protective film is lifted is transferred to the film-tearing station by a rotating platform mechanism for film peeling. The film-tearing equipment provided in this application separates the film-lifting process from the film-tearing process, has wide applicability, high adaptability to products, and can improve the customization of the equipment.
