Description

Technical Field

[0001] The invention relates to the technical field of protective films, in particular to a film tearing machine for quickly tearing films. Background Art

[0002] Nowadays, common LCD panels are affixed with a layer of protective film to reduce the contact of dust and other impurities with the LCD panel and protect the LCD panel. Common protective films are now produced with dust-proof films attached to the upper and lower surfaces respectively. The upper and lower dust-proof films can effectively protect the protective film and reduce pollution of the protective film.

[0003] The common method of attaching the protective film is to manually peel off the top dust-proof film first, then put the LCD panel in contact with the protective film, let the protective film adhere to the LCD panel, and finally tear off the other layer of protection and bend the protective film.

[0004] Regarding the above technical conditions, there is also the defect that it is difficult to quickly separate the dustproof film and the protective film when peeling because the protective film and the dustproof film are made of relatively soft materials and are very tightly attached to each other, resulting in low efficiency.

[0005] Based on this, the present invention designs a film tearing machine that can quickly tear film to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a film tearing machine that can quickly tear off films to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a film peeling machine for fast film peeling, comprising a mounting frame, a movable seat slidably arranged on the mounting frame, an upper peeling device, and a placing plate for placing a protective film, wherein the placing plate is arranged on the mounting frame, an upper dust-proof film and a lower dust-proof film are attached to the protective film, and the lower dust-proof film and the upper dust-proof film are both larger than the protective film, and an adsorption hole is opened on the placing plate, and the adsorption hole is adsorbed on the lower dust-proof film, and the upper peeling device comprises a movable seat, a first adsorption cylinder, and a first cylinder, the first cylinder is fixedly arranged on the movable seat, and the movable seat slides on the mounting frame, the mounting plate is fixedly provided with a placing seat on the telescopic shaft of the first cylinder, the mounting plate is provided with a moving component for driving the movable seat to move, the placing seat is provided with a mounting block, the mounting block is fixedly provided with a first motor, and the first adsorption cylinder is fixedly provided with a first motor. The cylinder is coaxially fixed on the rotating shaft of the first motor, the first adsorption cylinder is located above the placing plate, and the placing seat is fixedly provided with a second cylinder, and a connecting plate is fixedly connected to the telescopic shaft of the second cylinder, and a pressure plate is fixedly provided on the connecting plate, and an adsorption layer is fixedly provided on the surface of the first adsorption cylinder, and a resistance plate is fixedly provided on the connecting plate; after the first adsorption cylinder is adsorbed on a corner of the upper dust-proof film and moves a certain distance, the pressure plate resists the upper dust-proof film and the pressure plate presses against the first adsorption cylinder, and then the moving seat continues to move for a certain distance and the mounting plate rises one end distance, and then the mounting plate is moved down for a certain distance while the moving seat continues to move, and at this time the resistance plate resists the upper dust-proof film, causing the upper dust-proof film to bend to form a smaller angle, and then the moving seat continues to move slowly. When the two corners of the dust-proof film are out of contact with the protective film, the moving seat accelerates.

[0008] The moving base continues to move slowly, and when two corners of the dust-proof film are separated from and contacted with the protective film, the effect of the upper dust-proof film on the belt sheet of the protective film is reduced, and the moving base moves quickly, which can quickly peel off the upper dust-proof film and achieve the effect of convenient separation of the dust-proof film and the protective film.

[0009] Preferably, a third cylinder is fixedly provided on the placement seat, and a telescopic shaft of the third cylinder is fixedly connected to the mounting block.

[0010] By adopting the above technical solution, driving the third cylinder can adjust the distance of the adsorption cylinder. When the adsorption cylinder contacts the upper dust-proof film, driving the third cylinder allows the adsorption cylinder to more fully contact the upper dust-proof film, thereby allowing the upper dust-proof film to be more stably adsorbed on the adsorption cylinder.

[0011] Preferably, a connecting seat is provided on the mounting frame, a rotating block is provided on the connecting seat, and the placement plate is fixedly provided on the rotating block.

[0012] By adopting the above technical solution, the placement plate is fixedly arranged on the rotating block, and the angle of the placement plate can be easily adjusted.

[0013] Preferably, when the first adsorption cylinder enters from one of the corners, the length direction of the first adsorption cylinder is not parallel to the two sides of the corner, and the first adsorption cylinder is in a horizontal state.

[0014] By adopting the above technical solution, the first adsorption cylinder enters from one of the corners and is not parallel to the length of the two sides of the corner, so that the upper dustproof film can be separated from the protective film more quickly.

[0015] Preferably, a sliding seat is slidingly provided on the mounting frame, a fourth cylinder is fixedly provided on the sliding seat, a fixed seat is fixedly provided on the telescopic shaft of the fourth cylinder, an adsorption plate is provided on the fixed seat, and a liquid crystal panel is adsorbed on the adsorption plate. When the upper dustproof film is torn off, the sliding seat is located above the placement plate, and the liquid crystal panel is placed on the protective film. A second moving component for driving the sliding seat to move is provided on the mounting frame.

[0016] By adopting the above technical solution, the sliding seat and the fourth cylinder are driven to place the liquid crystal panel on the protective film, which can facilitate the attachment of the protective film to the liquid crystal panel.

[0017] Preferably, a lower stripping device is provided on the mounting frame, and the lower stripping device includes a second adsorption cylinder, a fifth cylinder, and a connecting seat. The connecting seat is provided on the mounting frame, and the fifth cylinder is fixedly provided on the connecting seat. A connecting block is fixedly provided on the telescopic shaft of the fifth cylinder, and a second motor is fixedly provided on the connecting block. The second adsorption cylinder is coaxially fixed on the rotating shaft of the second motor, and a sixth cylinder is fixedly provided on the connecting seat. A tightening block is provided on the telescopic shaft of the sixth cylinder. After the second adsorption cylinder adsorbs the lower dust-proof film and moves a distance, the tightening block contacts the lower dust-proof film and presses the second adsorption cylinder at the same time, and then the sliding seat is moved.

[0018] By adopting the above technical solution, when the adsorption film is adsorbed on the liquid crystal panel, the second adsorption cylinder adsorbs and peels off the lower dustproof film. The principle is similar to that of the first adsorption cylinder, thereby achieving the effect of facilitating the peeling off of the lower dustproof film.

[0019] Preferably, the adsorption plate is provided with reinforcement holes, and the reinforcement holes are adsorbed on the protective film.

[0020] By adopting the above technical solution, the reinforcement holes are adsorbed on the protective film, which can reduce the risk of the lower dustproof film strips pulling the protective film down when the lower dustproof film is peeled off.

[0021] Preferably, a material discharge box is provided near one side of the mounting frame, the liquid crystal panel without film attached is placed in the material discharge box, and the adsorption plate is located in the material discharge box.

[0022] By adopting the above technical solution, multiple liquid crystal panels are placed in the discharge box, making it convenient for the adsorption plate to adsorb the liquid crystal panels.

[0023] When the first adsorption cylinder is adsorbed on a corner of the upper dust-proof film and moves a certain distance, the adsorption cylinder can first peel off the protective film at one corner of the upper dust-proof film, and then let the pressure plate resist on the upper dust-proof film while the pressure plate presses against the first adsorption cylinder to prevent the upper dust-proof film from falling off, and then the movable seat continues to move for a certain distance while the mounting plate rises one end distance, so that it tilts and moves up for a certain distance with the upper dust-proof film, and then let the mounting plate move down for a certain distance while the movable seat continues to move, so that the upper dust-proof film continues to move for a certain distance along the direction of the peeling corner, and then let the resistance plate resist on the upper dust-proof film, so that the upper dust-proof film bends to form a smaller angle, which is convenient for the peeling of the upper dust-proof film and the protective film, and then let the movable seat continue to move slowly. When two corners of the dust-proof film are detached from the contact with the protective film, the effect of the upper dust-proof film on the belt sheet of the protective film is reduced, and the movable seat moves quickly, which can quickly peel off the upper dust-proof film and achieve the effect of convenient separation of the dust-proof film and the protective film.

[0048] Reference Figures 1-9 , the upper stripping device 3 includes a moving seat 2, a first adsorption cylinder 17, and a first cylinder 18. The first cylinder 18 is fixedly arranged on the moving seat 2, and the moving seat 2 slides on the mounting frame 1. A mounting plate 19 is fixedly arranged on the telescopic shaft of the first cylinder 18, and a placement seat 20 is arranged on the mounting plate 19. A first component for driving the moving seat 2 to move is provided on the horizontal plate 11. The first moving component includes a third motor 21, a first moving plate 22, and a first rotating rod 23. A guide seat 24 is fixedly arranged on the horizontal plate 11. The third motor 21 is fixedly arranged It is placed on the horizontal plate 11, and the first movable plate 22 is fixedly connected to the movable base 2. A first movable groove 25 is provided on the first movable plate 22, and the first movable groove 25 is sleeved on the guide base 24. The rotating shaft of the third motor 21 is coaxially fixedly connected to the first rotating rod 23, and a first rotating hole 26 is provided on the first movable plate 22. The first rotating hole 26 is threadedly connected to the first rotating rod 23. The third motor 21 is driven to drive the first rotating rod 23 to rotate, thereby driving the first movable plate 22 to move, thereby driving the movable base 2 to move.

[0049] Reference Figures 1-9 A third air cylinder 27 is fixedly provided on the placement seat 20. The telescopic shaft of the third air cylinder 27 is fixedly connected to a mounting block 28. A first motor 29 is fixedly provided on the mounting block 28. The first adsorption cylinder 17 is coaxially fixedly provided on the rotating shaft of the first motor 29. A second air cylinder 30 is fixedly provided on the placement seat 20. A connecting plate 31 is fixedly provided on the telescopic shaft of the second air cylinder 30.

The adsorption layer in this embodiment is an adhesive layer. A contact plate 34 is fixedly provided on the connecting plate 31.

[0050] Reference Figures 1-17The process of peeling off the upper dust-proof film 12 is as follows: first, the third motor 21 is driven to position the first adsorption cylinder 17 above one corner of the upper dust-proof film 12, and then the first cylinder 18 is driven to move the first adsorption cylinder 17 toward the side of the upper dust-proof film 12, while adjusting the angle of the placement plate 4. When the first adsorption cylinder 17 contacts one of the corners, the length direction of the first adsorption cylinder 17 is not parallel to the two sides of the corner, and the first adsorption cylinder 17 is in a horizontal state.

[0051] Reference Figures 1-17 , then drive the first motor 29 to drive the first adsorption cylinder 17 to rotate slowly and drive the third motor 21 to make the movable base 2 move slowly in the direction of peeling. At this time, the first adsorption cylinder 17 adsorbs the upper dust-proof film 12 for rewinding. After rewinding for a period of time, drive the second cylinder 30 to move the pressing plate 32 toward the side of the first adsorption cylinder 17, so that the pressing plate 32 contacts the upper dust-proof film 12 and presses against the first adsorption cylinder 17. At this time, the first adsorption cylinder 17 stops rotating; then the movable base 2 continues to slowly move in the direction of peeling for a distance and the mounting plate 19 slowly rises one end distance, so that the pressing plate 32 pulls one corner of the upper dust-proof film 12 and fully opens the upper dust-proof film 12 along the direction of this corner;

[0052] Reference Figures 1-17 , then let the mounting plate 19 move down and the moving seat 2 continue to move in the stripping direction, let the first adsorption cylinder 17 approach the placement plate 4, and when the mounting plate 19 moves down, the resistance plate 34 resists the upper dust-proof film 12, and the resistance plate 34 resists the upper dust-proof film 12, causing the upper dust-proof film 12 to bend to form a smaller angle, and then let the moving seat 2 continue to move slowly; after the moving seat 2 moves an end distance, when the two corners of the dust-proof film are completely out of contact with the protective film 51, the speed of movement of the moving seat 2 gradually accelerates. When stripping, since the two corners of the upper dust-proof film 12 have been out of contact with the protective film 51, the gradual acceleration process prevents the upper dust-proof film 12 from lifting the protective film 51, thereby achieving the effect of convenient separation of the upper dust-proof film 12 and the protective film 51.

[0053] Reference Figure 2-Figure 11A sliding seat 35 is slidingly provided on the horizontal plate 11, and a second moving assembly for driving the sliding seat 35 to move is provided on the horizontal plate 11.

The second moving plate 37 is fixedly connected to the sliding seat 35. A second moving groove 40 is provided on the second moving plate 37, and the second moving groove 40 is sleeved on the placement block 39. The rotating shaft of the fourth motor 36 is coaxially fixedly connected to the second rotating rod 38, and a second rotating hole 41 is provided on the second moving plate 37. The second rotating hole 41 is threadedly connected to the second rotating rod 38. The fourth motor 36 is driven to drive the second rotating rod 38 to rotate, thereby driving the second moving plate 37 to move, thereby driving the sliding seat 35 to move.

[0054] Reference Figure 2-13 The sliding seat 35 and the moving seat 2 are respectively located on both sides of the horizontal plate 11. A fourth cylinder 42 is fixedly installed on the sliding seat 35. A fixed seat 43 is fixedly installed on the telescopic shaft of the fourth cylinder 42. A suction plate 44 is installed on the fixed seat 43. The suction plate 44 is also provided with the same suction holes 14 as the placement plate 4. At the same time, the suction plate 44 is also provided with an air suction pipe. When the suction plate 44 moves to the top of the discharge box 5, the fourth cylinder 42 is driven to allow the suction plate 44 to enter the discharge box 5, allowing the suction plate 44 to absorb the liquid crystal panel 6, thereby achieving the effect of facilitating the removal of the liquid crystal panel 6.

[0055] Reference Figure 2-Figure 14 After the upper dust-proof film 12 is separated from the protective film 51, the tank belt 10 is driven to move the connecting seat 7 to the same side as the adsorption plate 44. At this time, the fourth motor 36 is driven to move the sliding seat 35 toward the side of the placement plate 4, so that the adsorption plate 44 is located above the placement plate 4, and then the fourth cylinder 42 is driven to move the adsorption plate 44 downward, so that the lower surface of the liquid crystal panel 6 contacts the protective film 51, and at the same time, the placement plate 4 no longer adsorbs the lower dust-proof film 13; a placement groove is provided on the adsorption plate 44, and an adsorption hole 14 is also provided in the placement groove. After the protective film 51 is attached to the liquid crystal panel 6, the fourth cylinder 42 is driven to allow the liquid crystal panel 6 to be located in the placement groove. At this time, the adsorption holes 14 adsorb the liquid crystal panel 6 and the protective film 51 and rise together.

[0056] Reference Figure 2-Figure 12A lower stripping device 52 is provided on the mounting frame 1, and the lower stripping device 52 includes a second adsorption cylinder 45, a fifth cylinder 46, and a connecting seat 7. The connecting seat 7 is provided on the mounting frame 1, and the fifth cylinder 46 is fixedly provided on the connecting seat 7. A connecting block 48 is fixedly provided on the telescopic shaft of the fifth cylinder 46, and a second motor 49 is fixedly provided on the connecting block 48. The second adsorption cylinder 45 is coaxially fixed on the rotating shaft of the second motor 49. The second adsorption cylinder 45 is also provided with an adsorption layer identical to that of the first adsorption cylinder 17. A sixth cylinder 50 is fixedly provided on the connecting seat 7, and a receiving block 53 is fixedly provided on the telescopic shaft of the sixth cylinder 50, and a tightening block 47 is fixedly provided on the receiving block 53.

[0057] Reference Figure 2-Figure 17 When peeling off the lower dust-proof film 13, the fourth cylinder 42 is driven to make one corner of the lower dust-proof film 13 contact the second adsorption cylinder 45. At this time, the second motor 49 is driven to make the second adsorption cylinder 45 rotate slowly. At the same time, the fourth motor 36 is driven to make the sliding seat 35 move slowly toward the side away from the adsorption plate 44, so that the second adsorption cylinder 45 adsorbs the lower dust-proof film 13 and rotates. After the second adsorption cylinder 45 rotates for a certain period of time, the sixth cylinder 50 is driven to make the sixth cylinder 50 contract, so that the tightening block 47 is in contact with the lower dust-proof film 13 while tightening the second adsorption cylinder 45. At the same time, the second motor 49 stops rotating to prevent the lower dust-proof film 13 from separating from the second adsorption cylinder 45. Then the fourth cylinder 42 is driven to make the liquid crystal panel 6 continue to rise slowly. At the same time, the sliding seat 35 continues to move, so that one corner of the lower dust-proof film 13 is fully separated from the protective film 51.

[0058] Reference Figure 2-Figure 17 , and then drive the fourth cylinder 42 to move the liquid crystal panel 6 downward. At the same time, a pressing plate with the same function as the contact plate 34 is provided on the pressing block 47. The pressing plate contacts the lower dustproof film 13, so that the lower dustproof film 13 forms an angle. The smaller the angle, the easier it is for the lower dustproof film 13 to separate from the protective film 51; the sliding seat 35 moves, and after the two corners of the lower dustproof film 13 separate from the protective film 51, the fourth motor 36 is driven at this time to allow the sliding seat 35 to gradually accelerate. During the peeling process, since the two corners of the lower dustproof film 13 have been separated from the protective film 51, the gradual acceleration process prevents the lower dustproof film 13 from lifting the protective film 51, thereby achieving the effect of convenient separation of the lower dustproof film 13 and the protective film 51.

[0059] Reference Figure 2-Figure 17 A reinforcement hole 16 is provided on the adsorption plate 44, and the reinforcement hole 16 is adsorbed on the protective film 51. When the lower dust-proof film 13 is peeled off, the reinforcement hole 16 is adsorbed on both ends of the protective film 51 in the length direction, which can further prevent the belt from lifting the protective film 51 when the lower dust-proof film 13 is peeled off, thereby achieving the effect of strengthening and fixing the protective film 51.

[0060] The implementation principle of this embodiment is: when the dust-proof film is peeled off, the protective film 51 is first placed on the placement plate 4, and the adsorption holes 14 are allowed to adsorb the lower dust-proof film 13, and then the upper dust-proof film 12 is peeled off from the protective film 51 through the upper peeling device 3; then the tank belt 10 is driven to move the connecting seat 7 to the same side as the sliding seat 35, and then the liquid crystal panel 6 is placed on the protective film 51 through the adsorption plate 44, so that the protective film 51 is attached to the liquid crystal panel 6; finally, the lower dust-proof film 13 is peeled off from the protective film 51 through the lower peeling device 52, so as to facilitate the separation of the upper dust-proof film 12 and the lower dust-proof film 13 from the protective film 51, and at the same time achieve the effect of film tearing and film sticking integration.
