Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a film-removing device and method for large-size plate-shaped materials. Background Technology

[0002] Film-removing equipment is mainly used to remove the protective film from the surface of materials. In order to prevent surface damage to materials (such as chip substrates, glass, acrylic sheets, etc.) during the pre-treatment stage, a protective film is usually pasted on the surface of the material. However, during the production process, the film needs to be removed for subsequent processing.

[0003] Most existing film-tearing equipment uses a single-claw film-tearing structure. When tearing film longitudinally, the tearing stroke of a single-claw film-tearing structure requires at least twice the length of the protective film, which is not suitable for the production of large-size sheet materials. When tearing film laterally, there is a large adsorption force between the protective film and the material, and the protective film is easy to detach from the film-tearing claw.

[0004] Double-claw tearing structures also exist on the market. When tearing the film longitudinally, the tearing stroke of a double-claw tearing structure requires at least twice the length of the protective film, which is not suitable for the production of large-size sheet materials. Moreover, double-claw tearing structures are mostly fixed structures. When tearing the film laterally, the two claws simultaneously grip the protective film at both ends and then move away from the material to tear the film. There is an increased adsorption force between the protective film and the material, and the protective film is easy to detach from the tearing claws. There are also some double-claw tearing structures with sliding action. However, when the double-claw tearing structure slides from both ends to the middle to tear the film, it is easy to cause the corners on both sides to tear up and form a sharp corner in the middle, which damages the surface of the material.

[0005] In the existing technology, the film-tearing claws are mostly ordinary claws and flat-angle claws. Flat-angle claws are not easy to grip the protective film, and the protective film is easy to detach from the film-tearing claws when tearing the film. Summary of the Invention

[0006] The main objective of this invention is to provide a film-tearing device and method for large-size sheet materials, which solves the problems of low film-tearing efficiency, material panel damage, low clamping force of grippers, long stroke, and unsuitability for large-size sheet materials in existing film-tearing devices.

[0007] To achieve the above objectives, the present invention proposes a film-peeling device for large-size sheet materials, comprising:

[0008] The device includes a frame, a material loading mechanism, a first transfer mechanism, a second transfer mechanism, a film tearing mechanism, and a film collecting mechanism fixedly mounted on the frame. The second transfer mechanism has a material loading mechanism at its starting end, a conveyor roller conveyor, and a film tearing mechanism mounted above it. The tearing direction of the film tearing mechanism is perpendicular to the material loading direction of the second transfer mechanism. One end of the film tearing mechanism extends above the second transfer mechanism, and a film collecting mechanism is located directly below the extended end of the film tearing mechanism. First longitudinal slide rails are provided on both sides of the second transfer mechanism and the material loading mechanism. The first transfer mechanism is slidably connected to the first longitudinal slide rails via sliders. The sliding frame is located directly above the material loading mechanism and the second transfer mechanism. The film-tearing mechanism includes a first transverse slide rail, a film-tearing slide rail motor, a film-tearing fixing frame, a second longitudinal slide rail, a second longitudinal slide rail motor, and film-tearing components. The film-tearing fixing frame is connected to the first transverse slide rail and is driven by the film-tearing slide rail motor. The second longitudinal slide rail is fixedly installed on the lower end surface of the film-tearing fixing frame and is driven by the second longitudinal slide rail motor. Two film-tearing components with opposite directions of movement are connected to the second longitudinal slide rail via longitudinal sliders. The film-collecting mechanism is located at the end of the stroke of the film-tearing components along the direction of the first transverse slide rail, and the height of the film-collecting mechanism is not higher than that of the film-tearing components.

[0009] Furthermore, the film-tearing assembly includes a rubber roller, a clamping device, and a clamping sensor, the clamping sensor being disposed between the rubber roller and the clamping device, and an arc-shaped clamping groove being formed between the jaws of the clamping device.

[0010] Furthermore, the curvature of the arc-shaped groove is the same as or greater than the curvature of the outer ring surface of the rubber roller.

[0011] Furthermore, a sensor and a sensing plate are installed on the film-tearing fixing frame. The sensor is fixedly installed on the film-tearing fixing frame, and the sensing plate is fixedly connected to the longitudinal slider.

[0012] Furthermore, an ion fan is also fixedly installed on the frame, with the blowing end of the ion fan facing the second transfer mechanism, and the lower end face of the ion fan is flush with the upper end face of the second transfer mechanism.

[0013] Furthermore, the second longitudinal slide rail includes left and right spiral screws with opposite external threads at both ends of the outer ring surface. The left and right spiral screws are respectively connected to left and right spiral sliders that mesh with the external threads. The left and right spiral sliders are respectively connected to film-tearing components.

[0014] Furthermore, the clamping device includes a clamping cylinder, a clamping jaw fixing part, and a clamping jaw moving part. The clamping jaw fixing part is fixedly installed on one side of the clamping cylinder, and the clamping jaw moving part is linked to the cylinder head of the clamping cylinder. The arc-shaped clamping groove is composed of an arc-shaped groove opened on the contact surface of the clamping jaw fixing part and the clamping jaw moving part. The central axis of the arc-shaped clamping groove is on the same straight line as the central axis of the rubber roller.

[0015] Furthermore, the film collecting mechanism includes a film collecting mounting part, a film collecting gripper cylinder, a film collecting gripper, a swing arm, and a film collecting storage platform. A rotary motor is mounted on the film collecting mounting part, and a swing arm is fixedly connected to the output end of the rotary motor. A film collecting gripper cylinder is fixedly mounted on the swing arm, and a film collecting gripper is provided on the film collecting gripper cylinder. The film collecting storage platform is fixedly mounted on the frame and is located below the film collecting gripper.

[0016] A film-removing method for a large-size sheet material film-removing device includes the following steps:

[0017] S1 feeding: The stacked materials are uniformly placed into the loading mechanism, and the loading mechanism is used to tidy up the edges of the stacked materials.

[0018] S2 single-piece transfer: The first transfer mechanism picks up the top layer of material stacked in the material loading mechanism and transfers it to the top of the second transfer mechanism, where the second transfer mechanism adsorbs, fixes and supports the single-piece material above it.

[0019] S3 film tearing mechanism: The film tearing assembly moves the film tearing component to the end of its stroke away from the film taking-up mechanism via the first transverse slide rail. At the same time, the film tearing assembly is separated from the material above the two corners via the second longitudinal slide rail and then lowered so that the rubber roller is tightly attached to the protective film at the two corners of the material. The motor drives the rubber roller to rotate in the direction of rotation from the outer edge of the protective film to the center of the protective film. After the rubber roller lifts the protective film at the two corners of the material, the clamping sensor determines that the protective film has been lifted and controls the clamping device to clamp the two corners of the protective film. The film tearing assembly on both sides of the material moves towards each other via the second longitudinal slide rail. At the same time, the film tearing assembly moves towards the film taking-up mechanism via the first transverse slide rail. After the film tearing assembly reaches the preset position, the film tearing assembly moves away from each other via the second longitudinal slide rail. When the relative distance between the film tearing assemblies is the same as the width of the protective film, the longitudinal movement of the film tearing assembly stops. During this process, the first transverse slide rail maintains a constant speed and continuously drives the film tearing assembly towards the film taking-up mechanism.

[0020] In the S4 film collection mechanism, when the film tearing assembly arrives at the film collection unit, the film collection claws hold the protective film instead of the film tearing assembly. The rotating motor drives the swing arm and film collection claws to swing downwards quickly. The inertia of the protective film generated by the swing causes the protective film to detach from the material and fall onto the film collection storage table.

[0021] S5 feeding: The second transfer mechanism feeds the de-filmed material, and then repeats steps S1-4 to achieve automated film removal.

[0022] Furthermore, in step S2, the second transfer mechanism fixes the material by providing a material adsorption mechanism below the second transfer mechanism. The material adsorption mechanism ensures that the material will not shift or fluctuate during the film-tearing process.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention uses a second longitudinal slide rail to drive the film-tearing components on both sides of the material to move towards each other, facilitating rapid film removal. At the same time, the first transverse slide rail drives the film-tearing components to move towards the film-collecting mechanism. After the film-tearing components reach the preset position, the second longitudinal slide rail moves the film-tearing components away from each other to prevent sharp corners from forming in the middle after the edges are torn, which would damage the material surface during film removal. This achieves damage-free film removal with a high success rate.

[0025] 2. In this invention, the film-tearing mechanism and the film-collecting mechanism work together. When the film-tearing component arrives at the film-collecting mechanism, the film-collecting claws hold the protective film instead of the film-tearing component. The rotating motor drives the swing arm and the film-collecting claws to swing downwards quickly. The inertia of the protective film generated by the swing causes the protective film to detach from the material and fall onto the film-collecting storage table, effectively reducing the film-tearing stroke.

[0026] 3. The clamping device of the present invention forms an arc-shaped clamping groove between the clamping claws. The curvature of the arc-shaped clamping groove is the same as or greater than the curvature of the outer ring surface of the rubber roller. When the rubber roller lifts up the protective film and moves, the protective film is more easily clamped by the clamping claws along the arc-shaped clamping groove. Moreover, the clamping force of the claws is large during the film tearing movement, and the protective film is not easy to detach from the claws. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1-10 The example shown.

[0040] A large-size sheet material film-tearing device includes a frame 1, a material loading mechanism 2, a first transfer mechanism 3, a second transfer mechanism 4, a film-tearing mechanism 5, and a film-collecting mechanism 6 fixedly mounted on the frame 1. The second transfer mechanism 4 has the material loading mechanism 2 at its starting end and a conveyor roller conveyor 7. The film-tearing mechanism 5 is mounted above the second transfer mechanism 4, with its tearing direction perpendicular to the material loading direction of the second transfer mechanism 4. One end of the film-tearing mechanism 5 extends above the second transfer mechanism 4, and the film-collecting mechanism 6 is located directly below the extended end of the film-tearing mechanism 5. First longitudinal slide rails 8 are provided on both sides of the second transfer mechanism 4 and the material loading mechanism 2. The first transfer mechanism 3 is slidably connected to the first longitudinal slide rails 8 via sliders. Above the material loading mechanism 2 and the second transfer mechanism 4, the film-tearing mechanism 5 includes a first transverse slide rail 15, a film-tearing slide rail motor 9, a film-tearing fixing frame 11, a second longitudinal slide rail 12, a second longitudinal slide rail motor 13, and a film-tearing assembly 14. The first transverse slide rail 15 is connected to the film-tearing fixing frame 11, which is driven by the film-tearing slide rail motor 9. The second longitudinal slide rail 12 is fixedly installed on the lower end surface of the film-tearing fixing frame 11, which is driven by the second longitudinal slide rail motor 13. Two film-tearing assemblies 14 with opposite directions of movement are connected to the second longitudinal slide rail 12 via a longitudinal slider 16. The film-collecting mechanism 6 is located at the end of the stroke of the film-tearing assembly 14 along the direction of the first transverse slide rail 15, and the height of the film-collecting mechanism 6 is not higher than that of the film-tearing assembly 14.

[0041] like Figure 2 As shown, the bottom of the loading mechanism 2 is fixedly installed on the frame 1. Stacked materials are uniformly placed into the loading mechanism 2. The loading mechanism 2 is equipped with a lifting platform 21. The lifting platform 21 vertically transports the material 100 through a forklift 22. A positioning mechanism 23 is installed on one side of the forklift 22. The positioning mechanism 23 has five positioning devices: two telescopic positioning plates 24 arranged opposite each other, a fixed mounting plate 25 located at the bottom of the frame 1, and two long baffles 26 symmetrically arranged on the frame 1 and located on one side of the fixed mounting plate 25 at right angles. When the material 100 is placed on the lifting platform 21, the two telescopic positioning plates 24 arranged opposite each other cooperate with the fixed mounting plate 25 through the telescopic motor 27 to achieve the function of organizing the material 100. The baffles 26 located on one side of the fixed mounting plate 25 are used to prevent the material 100 from moving during the process of the loading mechanism 2 transporting the material 100 to the first transfer mechanism 3.

[0042] like Figure 1-4As shown, the second transfer mechanism 4 and the material loading mechanism 2 are provided with first longitudinal slide rails 8 on both sides. The first transfer mechanism 3 is slidably connected to the first longitudinal slide rail 8 via a slider. The first transfer mechanism 3 is slidably mounted directly above the material loading mechanism 2 and the second transfer mechanism 4. The first longitudinal slide rail 8 is provided with a drive mechanism 53. The movable frame 28 mounted on the first longitudinal slide rail 8 slides on the first longitudinal slide rail 8 via the drive mechanism 53. The movable frame 28 is connected to the support frame 29 for carrying the material 100 via a cylinder 30. The support frame 29 is provided with multiple adsorption cylinders 31 on one side. The power output end of the adsorption cylinder 31 is provided with multiple first transfer suction cups 32 for adsorbing the material 100. The first transfer suction cups 32 adsorb and fix the top layer of material 100 stacked on the material loading mechanism 2, thereby preventing the material 100 from detaching from the support frame 29 during the transfer process. When the material 100 is adsorbed and fixed on the support frame 29, the material 100 is transferred by the first longitudinal slide rails 8 on both sides. The material 100 is conveyed to the second transfer mechanism 4. While the first transfer suction cup 32 adsorbs the material 100, the blower 33 fixed on the frame 1 continuously blows air onto the material 100 to reduce the pressure and static electricity between the materials 100 and improve the material distribution rate. The second transfer mechanism 4 is arranged parallel to the first transfer mechanism 3. The second transfer mechanism 4 includes an adsorption mechanism 34 and a conveying roller 7. The adsorption mechanism 34 includes an adsorption mounting plate 35, a second adsorption cylinder 36, and adsorption suction cups 37. The adsorption mounting plate 35 is fixedly mounted with a second adsorption cylinder 36 for adsorbing the material 100. The second adsorption cylinder 36 is equipped with multiple adsorption suction cups 37 for adsorbing the material 100. The adsorption mechanism 34 is used to adsorb the material 100 so that the material 100 will not shift or fluctuate during the film tearing process. The conveying roller 7 is equipped with multiple rollers 38. After the film is torn, the adsorption mechanism 34 controls the adsorption suction cups 37 to stop adsorbing the material 100, so that the material 100 is discharged through the conveying roller 7.

[0043] like Figure 1 and Figure 5As shown, the film-tearing mechanism 5 includes a first transverse slide rail 15, a film-tearing slide rail motor 9, a film-tearing fixing frame 11, a second longitudinal slide rail 12, a second longitudinal slide rail motor 13, and a film-tearing assembly 14. An ion fan 10 is also fixedly installed on the frame 1. The film-tearing mechanism 5 moves the film-tearing assembly 14 to the film-tearing station 54 via the first transverse slide rail 15, and simultaneously separates the film-tearing assembly 14 above the two corners of the material 100 via the second longitudinal slide rail 12, and then lowers the film-tearing assembly 14 so that it tightly adheres to the protective film at the two corners of the material 100. During the film peeling process, the blowing end of the ion blower 10 faces the second transfer mechanism 4, and the lower end face of the ion blower 10 is flush with the upper end face of the second transfer mechanism 4. The ion blower 10 can prevent dust on the protective film of the material 100 from falling onto the surface of the material 100. The ion blower 10 can generate a large amount of ion airflow with positive and negative charges, which is then blown onto the surface of the material 100 to neutralize the charge on the surface of the material 100 and achieve the purpose of removing static electricity. This prevents the static electricity generated during the film peeling process from sticking to other parts, thereby improving the film peeling efficiency and quality.

[0044] like Figure 5-8 As shown, a sensor 51 and a sensing plate 52 are installed on the film-tearing fixing frame 11. The sensor 51 is fixedly installed on the film-tearing fixing frame 11. The second longitudinal slide rail 12 includes left and right spiral screws 39 with opposite external threads at both ends of the outer ring surface. Two longitudinal sliders 16 are respectively installed on the two opposite external threads of the left and right spiral screws 39 and are engaged with the external threads. The longitudinal sliders 16 are fixedly connected to the sensing plate 52. The two longitudinal sliders 16 are left-handed slider 40 and right-handed slider 41, respectively. A film-tearing assembly 14 is installed on the two longitudinal sliders 16. Driven by the second longitudinal slide rail motor 13, the film-tearing assembly 14 moves at the same speed but in opposite directions. The film-tearing assembly 14 includes a rubber roller 17, a clamping device 18, and a clamping sensor. 19. The clamping sensor 19 is located between the rubber roller 17 and the clamping device 18. The clamping device 18 includes a clamping cylinder 42, a clamping jaw fixing part 46, and a clamping jaw moving part 45. The clamping jaw fixing part 46 is fixedly installed on one side of the clamping cylinder 42. The clamping jaw moving part 45 is linked to the cylinder head of the clamping cylinder 42. The arc grooves opened on the contact surfaces of the clamping jaw fixing part 46 and the clamping jaw moving part 45 form an arc-shaped clamping groove 20. The central axis of the arc-shaped clamping groove 20 is on the same straight line as the central axis of the rubber roller 17, and the curvature of the arc-shaped clamping groove 20 is the same as or slightly larger than the curvature of the outer ring surface of the rubber roller 17. The clamping sensor 19 is fixedly installed on the clamping jaw fixing part 46 to sense whether the protective film of the rubber roller 17 has been successfully lifted.

[0045] like Figure 9-10As shown, the film collection mounting part 47 is mounted on the frame 1 on the side away from the second transfer mechanism 4. A rotary motor 56 is mounted on the film collection mounting part 47. A swing arm 55 is fixedly connected to the output end of the rotary motor 56. A film collection gripper cylinder 48 is fixedly mounted on the swing arm 55. A film collection gripper 49 is provided on the film collection gripper cylinder 48. A film collection storage table 50 is fixedly mounted on the frame and is located below the film collection gripper 49.

[0046] This invention also provides a film-peeling method, which uses the aforementioned large-size plate-shaped material film-peeling equipment to peel the film, including the following steps:

[0047] S1 feeding: The stacked materials are uniformly stacked into the loading mechanism 2, and the loading mechanism 2 is used to tidy up the edges of the stacked materials.

[0048] S2 single-piece transfer: The first transfer mechanism 3 picks up the top layer of material stacked in the material loading mechanism 2 and transfers it to the top of the second transfer mechanism 4. The second transfer mechanism 4 adsorbs, fixes and supports the single piece of material above it.

[0049] S3 Film Tearing: The film tearing mechanism 5 moves the film tearing assembly 14 to the end of its stroke away from the film receiving mechanism 6 via the first transverse slide rail 15. Simultaneously, it separates the film tearing assembly 14 above the two corners of the material 100 via the second longitudinal slide rail 12, and then lowers the film tearing assembly 14 so that the rubber roller 17 tightly adheres to the protective film at the two corners of the material 100. The motor drives the rubber roller 17 to rotate in the direction of rotation from the outer edge of the protective film towards the center of the protective film. After the rubber roller 17 lifts the protective film at the two corners of the material 100, the clamping sensor 19 determines that the protective film has been lifted and controls... The clamping device 18 clamps the two corners of the protective film and drives the film-tearing components 14 on both sides of the material 100 to move towards each other through the second longitudinal slide rail 12. At the same time, the first transverse slide rail 15 drives the film-tearing components 14 to move towards the film-collecting mechanism 6. After the film-tearing components 14 reach the preset position, the second longitudinal slide rail 12 drives the film-tearing components 14 to move away from each other. When the relative distance between the film-tearing components 14 is the same as the width of the protective film, the longitudinal movement of the film-tearing components 14 stops. During this process, the first transverse slide rail 15 maintains a constant speed and continuously drives the film-tearing components 14 to move towards the film-collecting mechanism 6.

[0050] S4 Film collection: When the film tearing assembly 14 arrives at the film collection mechanism 6, the film collection claw 49 clamps the protective film instead of the film tearing assembly 14, and drives the swing arm 55 and the film collection claw 49 to swing rapidly downward through the rotary motor 56. The inertia of the rapid movement of the protective film generated by the swing causes the protective film to detach from the material 100 and fall onto the film collection storage table 50.

[0051] S5 feeding: The second transfer mechanism 4 feeds the de-filmed material 100, and then repeats the steps of S1-4 to achieve automated film removal.

[0052] Step S2 includes: the second transfer mechanism (4) fixes the material (100) by providing a material adsorption mechanism (34) below the second transfer mechanism (4), so that the material (100) will not shift or fluctuate during the film tearing process.

[0053] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.

The blowing end of the ion fan (10) faces the second transfer mechanism (4), and the lower end face of the ion fan (10) is flush with the upper end face of the second transfer mechanism (4).

3. A film-peeling method for a large-size plate-shaped material peeling device according to any one of claims 1-2, characterized in that, Includes the following steps: S1 feeding: The stacked materials (100) are uniformly stacked into the loading mechanism (2), and the loading mechanism (2) is used to tidy up the edges of the stacked materials (100); S2 single-piece transfer: the top layer of material (100) stacked in the material loading mechanism (2) is picked up by the first transfer mechanism (3) and transferred to the top of the second transfer mechanism (4). The second transfer mechanism (4) adsorbs, fixes and supports the single-piece material (100) above it. S3 Film Tearing: The film tearing mechanism (5) moves the film tearing assembly (14) to the end of its stroke away from the film receiving mechanism (6) via the first transverse slide rail (15). At the same time, it separates the film tearing assembly (14) above the two corners of the material (100) via the second longitudinal slide rail (12) and moves the film tearing assembly (14) down so that the rubber roller (17) is tightly attached to the protective film at the two corners of the material (100). The motor drives the rubber roller (17) to rotate, and the rotation direction is from the bottom of the rubber roller (17) to the center of the protective film. After the rubber roller (17) lifts the protective film at the two corners of the material (100), the clamping sensor (19) determines that the protective film has been lifted and controls the control. The clamping device (18) clamps the two corners of the protective film and drives the tearing film components (14) on both sides of the material (100) to move towards each other through the second longitudinal slide rail (12). At the same time, the tearing film components (14) are driven to move towards the film receiving mechanism (6) through the first transverse slide rail (15). After the tearing film components (14) reach the preset position, the tearing film components (14) are moved away from each other through the second longitudinal slide rail (12). When the relative distance between the tearing film components (14) is the same as the width of the protective film, the longitudinal movement of the tearing film components (14) is stopped. During this process, the first transverse slide rail (15) maintains a constant speed and continuously drives the tearing film components (14) to move towards the film receiving mechanism (6). S4 film collection: When the film tearing assembly (14) arrives at the film collection mechanism (6), the film collection claw (49) clamps the protective film instead of the film tearing assembly (14), and drives the swing arm (55) and the film collection claw (49) to swing rapidly downward through the rotary motor (56). The inertia of the rapid movement of the protective film generated by the swing causes the protective film to detach from the material (100) and fall onto the film collection storage table (50). S5 feeding: The de-filmed material (100) is fed through the second transfer mechanism (4), and then the steps S1-S4 are repeated to achieve automated film removal.

4. The film-peeling method of a large-size plate-shaped material peeling device according to claim 3, characterized in that, In step S2, the second transfer mechanism (4) fixes the material (100) by providing a material adsorption mechanism (34) below the second transfer mechanism (4). The material adsorption mechanism (34) ensures that the material (100) will not shift or fluctuate during the film tearing process.
