Description

Technical Field

[0001] This invention relates to the field of electronic paper production technology, specifically to an FPL film-tearing device for electronic paper production. Background Technology

[0002] Electronic paper, also known as digital paper, is an ultra-thin and ultra-light display screen, meaning a "paper-thin, flexible, and erasable display." Figuratively speaking, electronic paper is a thin film, and the layer of charged material "coated" on the film is electronic ink. Using electrophoretic display technology as the display panel, its display effect is close to that of natural paper, eliminating reading fatigue. Generally, display technologies that achieve paper-like reading comfort, ultra-thinness, lightness, flexibility, and ultra-low power consumption are called electronic paper technology. In the electronic paper production process, FPL (front panel) peeling is a crucial step, usually requiring FPL peeling equipment to complete this task precisely and efficiently. FPL peeling refers to the process of precisely peeling off the protective film or other functional films covering the front of the electronic paper display panel during the electronic paper manufacturing process. This step is essential for ensuring the quality of the electronic paper display and the smooth progress of subsequent assembly. In the production process of electronic paper, when using FPL film-tearing equipment to assist in film tearing, the adhesion between the film and the substrate is limited and has an impact. There is a lot of resistance during the film tearing process, resulting in insufficient smoothness of film tearing. This can easily cause unevenness between the film and the substrate, which in turn affects the production efficiency and quality of electronic paper. Summary of the Invention

[0006] Preferably, the driving component includes a servo motor, which serves as the power source. The servo motor is fixedly mounted on the outer surface of the frame. A lead screw is fixedly connected to the output shaft end of the servo motor, which converts the rotational motion of the servo motor into linear motion, thereby achieving precise movement of the pallet. A connecting plate is rotatably connected to the end of the lead screw away from the servo motor, ensuring the stability of the lead screw's rotation. The bottom surface of the connecting plate is fixed to the inner wall of the frame. A movable frame is drivenly connected to the outer edge surface of the lead screw, which supports the pallet and moves under the drive of the lead screw.

A hinge plate is fixedly installed on the bottom surface of the inclined plate away from the adhesive strip. An arc-shaped extrusion plate is hinged to the outer edge surface of the hinge plate. The spring-loaded component is installed between the inclined plate and the arc-shaped extrusion plate. The arc-shaped extrusion plate and the adhesive strip are used to extrude the electronic paper film during the film-tearing process, helping to separate the film. The adhesive strip can increase the contact area with the film and improve the film-tearing effect.

[0008] Preferably, the rebound component includes a mounting block for mounting and fixing other components. The top of the mounting block is fixed to the outer edge surface of the inclined plate. An outer straight cylinder is fixedly connected to the bottom surface of the mounting block, providing support and guidance. A collar is fixedly installed at the bottom of the inner wall of the mounting block, serving as a limiting and protective component to prevent loosening or detachment. A bent rod is slidably fitted onto the inner edge surface of the collar, transmitting a pushing force to achieve the pushing function of the arc-shaped extrusion plate. The bottom end of the bent rod is connected to the inner arc surface of the arc-shaped extrusion plate via a ball joint. A slider is fixedly connected to the top of the inner wall of the outer straight cylinder, allowing the slider to slide within the outer straight cylinder and move the bent rod. The outer edge surface of the slider slides against the inner edge surface of the outer straight cylinder. A spring is fixedly connected to the top of the slider, with the top of the spring fixed to the top of the inner cavity of the outer straight cylinder, providing elastic force and serving a resetting function.

[0009] Preferably, the limiting pressure film component includes an arc-shaped limiting plate, which restricts the movement range of the electronic paper film material and prevents it from deviating. The arc-shaped limiting plate is fixedly installed on the side of the bonding strip. A counterweight block is fixedly installed on the inner arc surface of the arc-shaped limiting plate. A connecting plate is fixedly installed on one side surface of the counterweight block. The side of the connecting plate away from the counterweight block is fixed to the outer surface of the inclined plate.

[0010] Preferably, the film material locking device includes a mounting frame, which supports and fixes other components to ensure the overall structural stability of the equipment. One side of the mounting frame is fixed to the side of the control device, and the inner wall of the mounting frame away from the control device is fixed to the outer edge surface of the frame. A lifting drive is installed on the top of the inner wall of the mounting frame, and a clamping device is installed at the output end of the lifting drive. A limiter is installed on the side of the clamping device away from the film spreader. The lifting drive controls the lifting movement of the components to cooperate with the clamping device to fix the end of the film material.

[0011] Preferably, the lifting drive component includes a fixed plate, the top of which is fixed to the top of the inner wall of the mounting frame, and symmetrically arranged drive cylinders are fixedly installed on the bottom surface of the fixed plate. The drive cylinders provide power to realize the extension and retraction of the component. A horizontal plate is fixedly connected to the output end of the drive cylinder. The horizontal plate plays a connecting and supporting role, increasing the stability of the structure. A vertical plate is fixedly installed on the inner wall of the fixed plate.

[0012] Preferably, the preheater includes an electric heater that provides a heat source. The electric heater includes a heating element, insulating material, and a shell, but is not limited to these. The electric heater is fixedly installed on the inner wall of the fixed plate. A heat transfer device is fixedly connected to the output end of the electric heater. The heat transfer device improves heat transfer efficiency and accelerates the preheating process. A heat-conducting plate is fixedly installed on one side surface of the heat transfer device. The heat-conducting plate evenly transfers heat to the spreading component and the limiting pressure film component to ensure the preheating effect. The heat-conducting plate is fixedly installed on the outer edge surface of the inclined plate. The heat-conducting plate is made of a high thermal conductivity material, such as aluminum, copper, or other metal materials or ceramic materials.

[0013] Preferably, the clamping device includes an upper clamp, the outer edge surface of which is fixed to the inner wall of the horizontal plate, and a lower clamp directly below the upper clamp. The upper and lower clamps work together to clamp the electronic paper film. The bottom side of the vertical plate is fixed to the outer surface of the lower clamp, and the outer surface of the upper clamp slides against the side of the vertical plate. Engaging pads are fixedly installed on the inner walls of both the upper and lower clamps away from the vertical plate. These pads protect the electronic paper film and prevent it from being clamped. If damaged during the process, a biting tooth seat is fixedly installed on the surface of the lower clamp near the vertical plate. A biting tooth plate is provided above the biting tooth seat. The top of the biting tooth plate is fixed to the bottom surface of the upper clamp, and the bottom surface of the biting tooth plate is adapted to the top of the biting tooth seat. A fixing frame is fixedly installed on the outer surface of the lower clamp. The end of the fixing frame away from the lower clamp is fixed to the outer surface of the inclined plate. The biting tooth seat and the biting tooth plate cooperate with each other to achieve the clamping and fixing of the electronic paper film material.

[0014] Preferably, the limiting member includes a base block, one side of which is fixed to the outer surface of the lower clamp, and a slide rod is fixedly connected to the top of the base block. The slide rod provides guidance for the movement of the component, and a sleeve block is slidably adapted on the outer edge surface of the slide rod. One side of the sleeve block is fixed to the outer surface of the upper clamp.

[0015] This invention provides an FPL tear-off device for electronic paper production. It has the following beneficial effects:

[0016] I. The FPL film-tearing equipment for electronic paper production uses a film locking device to secure the film end of the electronic paper. It then utilizes an electronic paper mover and a feeder to advance the electronic paper and achieve the film-tearing process. Simultaneously, a preheater is used to increase the contact temperature between the film spreader and the film, preheating the film to reduce stress during tearing and thus improve the smoothness of the tearing process. Furthermore, the film spreader ensures that the tearing force at the film-substrate interface remains consistent, reducing tearing stress and achieving smooth film separation with uniform external force. This prevents uneven tearing between the film and substrate, thereby ensuring the production efficiency and quality of the electronic paper.

[0017] II. The FPL film-tearing equipment for electronic paper production, through the contact between the bonding strip and the arc-shaped extrusion plate with the film surface, ensures that during film tearing, the bonding strip is pressed onto the film by the weight of the inclined plate and the limiting pressure component. In conjunction with the film locking device to fix the film and the electronic paper mover to move the film, the film tearing surface can be kept on the same horizontal line. Furthermore, by utilizing the hinge between the hinge plate and the arc-shaped extrusion plate, the arc-shaped extrusion plate is affected by the elastic force of the spring component, pushing the bent rod to squeeze the arc-shaped extrusion plate so that it is tightly attached to the film. This ensures that the film tearing force in the contact area with the arc-shaped extrusion plate is limited within the bonding range of the arc-shaped extrusion plate, thereby ensuring the stability of the film tearing process.

[0018] Third, the FPL film-tearing equipment for electronic paper production, through the combination of counterweight blocks and arc-shaped limiting plates, not only increases the weight of the inclined plate to ensure the bonding pressure applied to the film material by the bonding strip during film tearing, but also further restricts the movement range of the film material. The coordinated movement of the bonding strip prevents the film material from shifting after tearing, thereby ensuring the accuracy of the film tearing process.

[0019] IV. The FPL film-tearing equipment for electronic paper production provides heat through the cooperation of electric heaters and heat transfer devices. It uses the principle of heat conduction to transfer heat to the spreading and limiting pressing components. By adhering to the film material, the heat is evenly transferred to the film material to improve the smoothness of the film-tearing process. In conjunction with the film spreader, it achieves smooth separation of the film material with uniform external force, thereby reducing the resistance of the film-tearing process.

[0020] 5. The FPL film-tearing equipment for electronic paper production uses a drive cylinder and a horizontal plate to move the upper clamping seat towards the lower clamping seat. The biting tooth seat and biting tooth plate bite the end of the film material to clamp the electronic paper film material and prevent it from moving during the film-tearing process. The symmetrical arrangement of the biting soft pads protects the film material and avoids damage during the clamping process, which would affect the stability of the film-tearing process.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution: an FPL film-tearing device for electronic paper production, comprising a frame 1, a control device 2 fixedly installed on the top of the frame 1, a feeder 3 fixedly installed on one side of the frame 1, an electronic paper mover 4 installed on the top of the frame 1 and disposed on one side of the feeder 3, a film locking device 7 installed on one side of the control device 2, the film locking device 7 being disposed above the electronic paper mover 4, the electronic paper mover 4 being used to support the electronic paper, and a film spreader 5 installed on one side of the film locking device 7, the bottom surface of the film spreader 5 being in contact with the electronic paper supported on the top of the electronic paper mover 4, and a film locking device 7 being mounted on the film locking device 7. Equipped with a preheater 6, the output end of which is connected to the outer edge surface of the film spreader 5, the film is used to transfer heat to preheat the film material on the surface of the electronic paper. The film material end of the electronic paper is fastened by the film material locker 7, and the electronic paper is pushed and moved by the electronic paper mover 4 and the feeder 3 to realize the film tearing process. At the same time, the preheater 6 is used to increase the contact temperature between the film spreader 5 and the film material, preheating the film material and reducing the stress during film tearing. The film spreader 5 is used to keep the film material and the electronic paper substrate at the same level of tearing force at the tearing interface, reducing the tearing stress and achieving smooth separation of the film material with uniform external force.

[0034] The electronic paper mover 4 includes a drive unit 41, which is installed inside the frame 1. A tray 42 is mounted on the output end of the drive unit 41. A mounting groove is formed on the top of the tray 42, and a negative pressure fixture 43 is fixedly installed on the inner wall of the mounting groove to adsorb and fix the electronic paper. A sliding seat 44 is provided on the bottom surface of the tray 42. The bottom surface of the sliding seat 44 is fixed to the top of the frame 1 and symmetrically arranged about the center line of the tray 42. The bottom surface of the tray 42 slides against the top of the sliding seat 44. The drive unit 41 includes a servo motor 411, which is fixedly installed on the outside of the frame 1. On the surface, a lead screw 412 is fixedly connected to the output shaft end of the servo motor 411. A connecting plate 45 is rotatably connected to the end of the lead screw 412 away from the servo motor 411. The bottom surface of the connecting plate 45 is fixed to the inner wall of the frame 1. A movable frame 413 is connected to the outer edge surface of the lead screw 412. The top of the movable frame 413 is fixed to the bottom surface of the tray 42. The electronic paper is fixed by the negative pressure adsorption of the negative pressure fixture 43. Then, the output shaft of the servo motor 411 rotates, which drives the lead screw 412 to rotate, so that the movable frame 413 and the tray 42 move and drive the electronic paper on them to move synchronously.

[0035] The film spreader 5 includes a spreading member 51, which is installed on the output end of the film locking device 7. The end of the spreading member 51 away from the film locking device 7 is in contact with the electronic paper supported on the surface of the tray 42. A limiting film pressing member 52 is installed on the side of the spreading member 51 away from the film locking device 7. A spring-loaded member 53 is installed on the outer edge surface of the spreading member 51 near the film locking device 7. By limiting the film pressing member 52 to make front contact with the film, the position of the electronic paper film is restricted, ensuring the accuracy of film tearing. The spreading member 51 is used to flatten the electronic paper and film. The elastic force provided by the spring-loaded member 53 to the spreading member 51 ensures the contact force between the spreading member 51 and the film, improving the film tearing effect.

[0036] During operation, the operator places the electronic paper on the tray 42, uses the negative pressure fixing device 43 to adsorb and fix the electronic paper, and then uses the film locking device 7 to fasten the film end of the electronic paper. The output shaft of the servo motor 411 rotates, driving the lead screw 412 to rotate, causing the moving frame 413 and the tray 42 to move synchronously, and the electronic paper on them to move synchronously. This, combined with the feeder 3, propels the electronic paper to achieve the film-tearing process. Simultaneously, the preheater 6 increases the contact temperature between the spreading component 51 and the limiting film pressing component 52 and the film material, preheating the film material to reduce stress during film tearing. By using the limiting pressure member 52 to make front contact with the film material, the position of the electronic paper film material is restricted, and the spreading member 51 is used to flatten the electronic paper and film material. With the elastic force provided by the spring member 53 to the spreading member 51, the contact force between the spreading member 51 and the film material is ensured, so that the tearing force at the film material and the electronic paper substrate is always the same, reducing the tearing stress and achieving smooth separation of the film material with uniform external force. After the tearing is completed, the electronic paper is released by the negative pressure retainer 43 and transported to the next processing step. The film material is then removed for subsequent electronic paper tearing processing.

[0037] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 8 As shown, the spreading component 51 includes an inclined plate 511. The side of the inclined plate 511 is connected to the output end of the film material locking device 7. An adhesive strip 513 is fixedly installed at the bottom end of the inclined plate 511. The bottom surface of the adhesive strip 513 is in contact with the electronic paper supported on the surface of the support plate 42. A hinge plate 514 is fixedly installed on the bottom surface of the inclined plate 511 away from the adhesive strip 513. An arc-shaped extrusion plate 512 is hinged to the outer edge surface of the hinge plate 514. A spring-loaded component 53 is installed between the inclined plate 511 and the arc-shaped extrusion plate 512. Through the contact between the adhesive strip 513 and the arc-shaped extrusion plate 512 and the film material surface, when the film is peeled off, the adhesive strip 513 is affected by the weight of the inclined plate 511 and the limiting film pressing component 52 and is pressed onto the film material. With the film material locking device 7 fixing the film material and the electronic paper moving device 4 driving the film material to move, the peeling surface of the film material is kept on the same horizontal line.

[0038] The spring-loaded component 53 includes a mounting block 533. The top of the mounting block 533 is fixed to the outer edge surface of the inclined plate 511. An outer straight cylinder 531 is fixedly connected to the bottom surface of the mounting block 533. A collar 536 is fixedly installed at the bottom end of the inner wall of the mounting block 533. A bent rod 532 is adapted to slide on the inner edge surface of the collar 536. The bottom end of the bent rod 532 is connected to the inner arc surface of the arc-shaped extrusion plate 512 by a ball joint. A slider 535 is fixedly connected to the top end of the inner wall of the outer straight cylinder 531 where the bent rod 532 extends. The outer edge surface of the slider 535 is connected to the outer straight cylinder. The inner edge surface of 531 slides together. The top of the slider 535 is fixedly connected to the spring 534. The top of the spring 534 is fixed to the top of the inner cavity of the outer straight cylinder 531. By using the hinge between the hinge plate 514 and the arc-shaped extrusion plate 512, the arc-shaped extrusion plate 512 is affected by the elastic force of the spring 534, pushing the bent rod 532 to squeeze the arc-shaped extrusion plate 512 so that it is tightly attached to the film material. This ensures that the film tearing force in the contact area with the arc-shaped extrusion plate 512 is limited to the contact range of the arc-shaped extrusion plate 512, thereby ensuring the stability of the film tearing process.

[0039] The limiting pressure film component 52 includes an arc-shaped limiting plate 521, which is fixedly installed on the side of the bonding strip 513. A counterweight block 523 is fixedly installed on the inner arc surface of the arc-shaped limiting plate 521. A connecting plate 522 is fixedly installed on one side surface of the counterweight block 523. The side of the connecting plate 522 away from the counterweight block 523 is fixed to the outer surface of the inclined plate 511. The counterweight block 523 and the arc-shaped limiting plate 521 increase the weight of the inclined plate 511, ensuring the bonding pressure applied to the film material by the bonding strip 513 when tearing the film. This also further limits the range of movement of the film material. The coordinated movement with the bonding strip 513 prevents the film material from shifting after tearing, thereby ensuring the accuracy of the tearing process.

[0040] During operation, the weight of the inclined plate 511 is increased by the counterweight block 523 and the arc-shaped limiting plate 521, ensuring the bonding pressure applied to the film material by the bonding strip 513 during film removal, further limiting the range of movement of the film material. The coordinated movement of the bonding strip 513 prevents the film material from shifting after being removed. Utilizing the contact between the bonding strip 513 and the arc-shaped extrusion plate 512 and the surface of the film material, the bonding strip 513 is pressed against the film material by the weight of the inclined plate 511 and the limiting pressure member 52 during film removal. The film material is fixed by the film material locking device 7 and moved by the electronic paper mover 4, so that the tearing surface of the film material is kept on the same horizontal line. By using the hinge between the hinge plate 514 and the arc-shaped extrusion plate 512, the arc-shaped extrusion plate 512 is affected by the elastic force of the spring member 534, pushing the bent rod 532 to squeeze the arc-shaped extrusion plate 512 so that it is tightly attached to the film material, ensuring that the tearing force of the film material in the contact area with the arc-shaped extrusion plate 512 is limited to the contact range of the arc-shaped extrusion plate 512.

[0041] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 3 , Figure 5 , Figure 9 , Figure 10 As shown, the film material locking device 7 includes a mounting frame 71. One side of the mounting frame 71 is fixed to the side of the control device 2. The inner wall of the mounting frame 71 away from the control device 2 is fixed to the outer edge surface of the frame 1. A lifting drive 72 is installed on the top of the inner wall of the mounting frame 71. A clamping fastener 73 is installed at the output end of the lifting drive 72. A limiting member 74 is installed on the side of the clamping fastener 73 away from the film spreader 5.

[0042] The lifting drive component 72 includes a fixed plate 721, the top of which is fixed to the top of the inner wall of the mounting bracket 71. Symmetrically arranged drive cylinders 722 are fixedly mounted on the bottom surface of the fixed plate 721. A horizontal plate 723 is fixedly connected to the output end of the drive cylinders 722. A vertical plate 724 is fixedly mounted on the inner wall of the fixed plate 721. The preheater 6 includes an electric heater 61, which is fixedly mounted on the inner wall of the fixed plate 721. A heat transfer device is fixedly connected to the output end of the electric heater 61. 63. A heat-conducting plate 62 is fixedly installed on one side surface of the heat transfer device 63. The heat-conducting plate 62 is fixedly installed on the outer edge surface of the inclined plate 511. Heat is provided by the electric heater 61 and the heat transfer device 63. The heat is transferred to the spreading member 51 and the limiting pressure member 52 by utilizing the principle of heat conduction. The heat is evenly transferred to the film material by utilizing the adhesion between the spreading member 51 and the limiting pressure member 52 and the film material, so as to improve the smoothness of the film tearing process and achieve smooth separation of the film material with uniform external force, thereby reducing the resistance of the film tearing process.

[0043] The clamping component 73 includes an upper clamping seat 731, the outer edge surface of which is fixed to the inner wall of the horizontal plate 723. A lower clamping seat 732 is disposed directly below the upper clamping seat 731. The bottom side of the vertical plate 724 is fixed to the outer surface of the lower clamping seat 732. The outer surface of the upper clamping seat 731 slides against the side of the vertical plate 724. Engaging pads 733 are fixedly installed on the inner walls of the surfaces of both the upper clamping seat 731 and the lower clamping seat 732 away from the vertical plate 724. An engagement tooth seat 735 is fixedly installed on the end surface of the lower clamping seat 732 near the vertical plate 724. An engagement tooth plate 736 is disposed above the engagement tooth seat 735. The top of the engagement tooth plate 736 is fixed to the bottom surface of the upper clamping seat 731, and the bottom surface of the engagement tooth plate 736 is adapted to the top of the engagement tooth seat 735. An engagement tooth plate 736 is fixedly installed on the outer surface of the lower clamping seat 732. The fixing frame 734 has one end away from the lower clamp 732 fixed to the outer surface of the inclined plate 511. The limiting member 74 includes a base block 741, one side of which is fixed to the outer surface of the lower clamp 732. A sliding rod 742 is fixedly connected to the top of the base block 741. A sleeve block 743 is slidably fitted on the outer edge surface of the sliding rod 742. One side of the sleeve block 743 is fixed to the outer surface of the upper clamp 731. The upper clamp 731 moves toward the lower clamp 732 by the cooperation of the drive cylinder 722 and the cross plate 723. The end of the film material is clamped by the biting tooth seat 735 and the biting tooth plate 736 to achieve clamping of the electronic paper film material and prevent it from moving during the film tearing process. The symmetrical arrangement of the biting soft pads 733 protects the film material and avoids damage during the clamping process, which would affect the stability of the film tearing.

[0044] During operation, the output shaft of the drive cylinder 722 extends and retracts, driving the horizontal plate 723 to descend, causing the upper clamp 731 to move towards the lower clamp 732. The biting tooth seat 735 and biting tooth plate 736 bite the end of the film material, clamping the electronic paper film material and preventing it from moving during the tearing process. The symmetrical arrangement of the biting soft pads 733 protects the film material, and heat is provided by the electric heater 61 and heat transferr 63. The heat is transferred to the spreading member 51 and the limiting film pressing member 52 using the principle of heat conduction. The adhesion between the spreading member 51 and the limiting film pressing member 52 and the film material evenly transfers heat to the film material, improving the smoothness of the tearing process. The film material is smoothly separated with uniform external force, reducing the resistance of the tearing process.

[0045] The working principle of the FPL film-tearing equipment for electronic paper production will be explained in detail below.

[0046] In use, the operator places the electronic paper on the tray 42 and uses the negative pressure retainer 43 to adsorb and fix the electronic paper. Then, the output shaft of the drive cylinder 722 extends and retracts, driving the horizontal plate 723 to descend, causing the upper clamp 731 to move towards the lower clamp 732. The biting tooth seat 735 and biting tooth plate 736 bite the end of the film material, clamping the electronic paper film material and preventing it from moving during the film tearing process. The symmetrical arrangement of the biting soft pads 733 protects the film material. The output shaft of the servo motor 411 rotates, driving the lead screw 41. 2. Rotation causes the moving frame 413 and tray 42 to move, driving the electronic paper on them to move synchronously. This, combined with the feeder 3, propels the electronic paper to achieve the film-tearing process. Simultaneously, the electric heater 61 and heat transfer device 63 provide heat, which is transferred to the spreading component 51 and the limiting film-pressing component 52 through heat conduction. The adhesion between the spreading component 51 and the limiting film-pressing component 52 and the film material ensures that the heat is evenly transferred to the film material, preheating it and reducing stress during film tearing. The counterweight block 523 and the arc-shaped limiting plate 521 further enhance the inclined plate 51. The weight of 1 ensures the bonding pressure applied to the film material by the bonding strip 513 during film removal, further limiting the movement range of the film material. The bonding strip 513 works in conjunction with the movement of the bonding strip 513 to prevent the film material from shifting after removal. Utilizing the contact between the bonding strip 513 and the arc-shaped extrusion plate 512 and the film material surface, the bonding strip 513 is pressed against the film material by the weight of the inclined plate 511 and the limiting pressure member 52 during film removal. This, combined with the film material locking device 7 fixing the film material and the electronic paper mover 4 moving the film material, keeps the tearing surface of the film material on the same horizontal line. The hinge plate 514... The hinge between the curved extrusion plate 512 and the curved extrusion plate 512 is influenced by the elastic force of the spring member 534, which pushes the bent rod 532 to squeeze the curved extrusion plate 512 tightly against the film material. This ensures that the tearing force of the film material in the contact area with the curved extrusion plate 512 is limited within the contact range of the curved extrusion plate 512, reducing tearing stress and achieving smooth separation of the film material with uniform external force. After tearing is completed, the electronic paper is released using the negative pressure retainer 43 and transported to the next processing step. The film material is then removed for subsequent electronic paper tearing processing. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art and related fields without creative effort should fall within the scope of protection of the present invention.
