A film slitting correction device for electronic equipment

Abstract

This invention discloses a film slitting and correction device for electronic devices, relating to the field of film slitting technology. It includes a first mounting frame and a second mounting frame. An unwinding roller is rotatably mounted on the first mounting frame, and an unwinding control unit for controlling the rotation of the unwinding roller is provided on one side of the first mounting frame. Multiple take-up rollers are mounted on the second mounting frame via roller shafts, with adjacent take-up rollers staggered. A take-up control unit for controlling the rotation of the take-up rollers is also provided on one side of the second mounting frame. By incorporating an adjusting platform and a slider, this invention can change the position of the slider within the sliding cavity of the adjusting platform based on the translation of the sliding seat. Since one end of the sliding cavity extends smoothly upwards at an angle, and the other end extends smoothly downwards at an angle, the height of the slider changes. This change in the height of the second correction bracket relative to the first correction bracket allows the correction roller to tilt within the annular ball seat based on the movement of the convex ball, thereby guiding the film material movement and achieving correction.

Description

Technical Field

[0001] This invention relates to the field of membrane slitting technology, and more particularly to a correction device for membrane slitting in electronic devices. Background Technology

[0002] In the field of electronic equipment manufacturing, thin film materials (such as optical films, protective films, and conductive films) are widely used in components such as displays, touch screens, and battery separators. During production, wide-width film materials typically need to be slit into multiple narrow strips for subsequent processing. The precision of the slitting process directly affects the quality and performance of the product. If problems such as misalignment, wrinkling, or uneven tension occur during slitting, it can lead to inconsistent slit widths, edge damage, or material waste, thereby affecting the reliability and yield of electronic devices.

[0003] Currently, common film slitting equipment typically includes unwinding, slitting, alignment, and rewinding sections. The alignment device is used to detect and adjust the position of the film material during transport in real time, preventing lateral deviation. Traditional alignment methods often employ pneumatic or electric actuators to move the alignment roller as a whole, or use fine-tuning of the oscillating roller angle to achieve alignment. However, these methods have the following shortcomings: Simple translational correction is prone to lag due to mechanical gaps and is not fine enough in correcting lateral deviations of the film material, making it difficult to achieve precise following, especially during high-speed slitting. Some correction systems use multiple independently driven roller systems, resulting in a cumbersome equipment layout and high maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a film slitting correction device for electronic devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A film slitting and correction device for electronic devices includes a first mounting frame and a second mounting frame.

Multiple take-up rollers are mounted on the second mounting frame via roller shafts, with adjacent take-up rollers staggered. A take-up control unit for controlling the rotation of the take-up rollers is provided on one side of the second mounting frame. A cutting mechanism for slitting the film material is provided between the first mounting frame and the take-up rollers.

[0009] As a preferred embodiment of the present invention: the first alignment bracket is equipped with a positioning component for limiting the angle of the mounting shaft. The positioning component includes a ball bearing seat, which is fixed to one end of the mounting shaft. The ball bearing seat is provided with a first annular groove, in which a plurality of balls are movably mounted. The portion of the balls located in the first annular groove is greater than half the volume of the balls. A positioning telescopic cylinder is fixed to the first alignment bracket. An annular ball bearing cover is fixed to the output end of the positioning telescopic cylinder. A second annular groove adapted to the balls is provided on the annular ball bearing cover. When the mounting shaft is horizontal, the positions of the first annular groove and the second annular groove are adapted to each other.

[0010] As a preferred embodiment of the present invention, the cutting mechanism includes a first support frame, a transverse support is mounted on the first support frame, a cutting frame is provided on the transverse support, and a cutting blade is mounted at the bottom of the cutting frame.

[0011] As a preferred embodiment of the present invention: a first electric telescopic cylinder is installed on the first support frame, a slide bracket is fixed to the output end of the first electric telescopic cylinder, two guide slides are installed on the slide bracket, ball joints are fixed to both sides of the cutter holder, the ends of the ball joints slide on the inner wall of the guide slides, the distance between the two guide slides is constant, and the top of the guide slides bends and extends to one side, the bottom of the guide slides bends and extends to the other side, and the cutter holder is slidably installed on the outer wall of the transverse support.

[0012] As a preferred embodiment of the present invention, it further includes a smoothing mechanism, which includes a third support frame, on which a second electric telescopic cylinder is mounted. A roller frame is mounted on the output end of the second electric telescopic cylinder. Rollers are rotatably mounted on the roller frame via a rotating shaft. The rollers on both sides are distributed in a figure-eight shape, and the spacing between them gradually increases towards both sides along the direction of film movement. A roller control motor for controlling the rotation of the rotating shaft is mounted on one side of the roller frame.

[0013] As a preferred embodiment of the present invention, it further includes a detection component, the detection component including a side bracket, an adjustable rod being mounted on the side bracket, and a threaded knob for fixing the adjustable rod being provided on the side bracket; one end of the adjustable rod is fixed to a detection frame, and a laser detection head is mounted on the detection frame.

[0015] The beneficial effects of this invention are as follows: 1. This invention, by setting up an adjustment platform, a slider, and other structures, can change the position of the slider in the sliding cavity of the adjustment platform based on the translation of the translation seat. Since one end of the sliding cavity extends smoothly upward at an angle and the other end extends smoothly downward at an angle, the height of the slider changes.

[0017] 3. By setting up a positioning component, the present invention can push the annular ball cover towards the ball seat when the mounting shaft is horizontal, based on the operation of the positioning telescopic cylinder, so that the first annular slide groove and the second annular slide groove merge. During the rotation of the mounting shaft, the first annular slide groove, the second annular slide groove and the ball cooperate to achieve stable rotation of the structure.

[0018] 4. By setting up a guide slide, ball head rod and other structures, the present invention can control the lifting and lowering of the guide slide based on the operation of the first electric telescopic cylinder. Since the top of the guide slide bends and extends to one side and the bottom of the guide slide bends and extends to the other side, the ball head rod can be moved by the guide slide to adjust the position of the cutter holder on the horizontal support, thereby achieving the purpose of adjusting the cutting position of the cutter.

Detailed Implementation

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1:

[0024] A film slitting correction device for electronic devices, such as Figure 1-6 As shown, the system includes a first mounting frame 1 and a second mounting frame 14. An unwinding roller 2 is rotatably mounted on the first mounting frame 1, and an unwinding control unit for controlling the rotation of the unwinding roller 2 is provided on one side of the first mounting frame 1. Multiple take-up rollers 17 are mounted on the second mounting frame 14 via roller shafts, with adjacent take-up rollers 17 staggered. A take-up control unit for controlling the rotation of the take-up rollers 17 is provided on one side of the second mounting frame 14. A cutting mechanism for slitting the film material 22 is provided between the first mounting frame 1 and the take-up rollers 17. One end of the film material 22 is wound around the unwinding roller 2, and the other end of the film material 22 is cut by the cutting mechanism and then taken up by the take-up rollers 17. A correction mechanism is provided between the cutting mechanism and the unwinding roller 2, and the correction mechanism includes: The second correction bracket 45 has a correction roller 44 rotatably mounted on it via a mounting shaft 51. The top surface of the correction roller 44 is in contact with the film material 22. The first correction bracket 41 is provided with an annular ball seat 43, and a convex ball 50 is fixed on the mounting shaft 51. The convex ball 50 is rotatably installed in the annular ball seat 43. The lifting control component is used to control the lifting of the second correction bracket 45. When the second correction bracket 45 is lifted, it is based on the rotation of the convex ball 50 to adjust the angle of the correction roller 44, thereby guiding the film material 22 to move and achieve correction.

[0025] The unwinding control unit includes an unwinding motor 4, which is mounted on the first mounting frame 1. The output end of the unwinding motor 4 is connected to the roller shaft of the unwinding roller 2 via the first gear transmission assembly 3.

[0026] The winding control unit includes a winding motor 16, which is mounted on a second mounting bracket 14. The output end of the winding motor 16 is connected to the roller shaft of the winding roller 17 via a second gear transmission assembly 15.

[0027] A second support frame 23 is provided on one side of the first mounting frame 1. Two auxiliary conveying rollers 24 are installed on the second support frame 23. The auxiliary conveying rollers 24 are located on the upper and lower sides of the film material 22.

[0028] To facilitate control of the raising and lowering of the second alignment bracket 45; such as Figure 2 , Figure 5 As shown, the lifting control assembly includes a translation seat 11 and a translation control unit for controlling the translation of the translation seat 11. An adjustment platform 12 is fixed on the top of the translation seat 11. A sliding cavity is provided in the adjustment platform 12. One end of the sliding cavity extends smoothly upward at an angle, and the other end extends smoothly downward at an angle. A mounting rod is fixed on one side of the second correction bracket 45. A slider 46 is fixed at one end of the mounting rod. The slider 46 slides in the sliding cavity. The distance between the top surface and the bottom surface of the sliding cavity is adapted to the diameter of the slider 46. By setting up structures such as the adjustment platform 12 and the slider 46, the position of the slider 46 in the sliding cavity of the adjustment platform 12 can be changed based on the translation of the translation seat 11. Since one end of the sliding cavity extends smoothly upward and the other end extends smoothly downward, the height of the slider 46 changes. The height of the second correction bracket 45 relative to the first correction bracket 41 changes, so that the correction roller 44 can tilt based on the convex ball 50 moving in the annular ball seat 43, thereby changing the angle and guiding the film material 22 to move, thus achieving correction.

[0029] To facilitate control of the translation of the translation seat 11; such as Figure 1 , Figure 5 As shown, the translation control unit includes a translation slide rail 10, and a translation seat 11 is slidably mounted on the translation slide rail 10. A movement control motor 8 is fixed on one side of the translation slide rail 10, and a translation control screw 9 is installed at the output end of the movement control motor 8. The translation control screw 9 is threadedly connected to the inner wall of the translation seat 11.

[0030] In order to better limit the left and right sway of the correction roller 44, such as Figure 5 As shown, a guide frame slide rail 38 is fixed on one side of the translation slide rail 10, a transverse electric telescopic cylinder 40 is fixed at one end of the guide frame slide rail 38, a guide frame 39 is fixed at the output end of the transverse electric telescopic cylinder 40, the guide frame 39 slides in the guide frame slide rail 38, and two upright plates are fixed on the top of the guide frame 39. The two upright plates are located on both sides of the mounting rod, and the distance between the upright plates is adapted to the diameter of the mounting rod. By setting up structures such as guide frame 39 and upright plate, the left and right swing of the mounting rod can be restricted, so that the second correction bracket 45 can only roll within the annular ball seat 43 based on the convex ball 50 to achieve up and down swing; Preferably, the distance between the two uprights is adjustable.

[0031] To facilitate stable support of the correction roller 44 in the non-correction state; such as Figure 5 , Figure 6 As shown, the first alignment bracket 41 is equipped with a positioning component for limiting the angle of the mounting shaft 51. The positioning component includes a ball bearing seat 42, which is fixed to one end of the mounting shaft 51. The ball bearing seat 42 is provided with a first annular groove, and a plurality of balls 48 are movably installed in the first annular groove. The portion of the balls 48 located in the first annular groove is larger than half the volume of the balls 48. A positioning telescopic cylinder 47 is fixed on the first alignment bracket 41, and an annular ball bearing cover 49 is fixed to the output end of the positioning telescopic cylinder 47. A second annular groove adapted to the balls 48 is provided on the annular ball bearing cover 49. When the mounting shaft 51 is horizontal, the positions of the first annular groove and the second annular groove are adapted to each other. By setting up a positioning component, the positioning telescopic cylinder 47 can be used to push the annular ball cover 49 toward the ball seat 42 when the mounting shaft 51 is in a horizontal state, so that the first annular slide groove and the second annular slide groove are merged. During the rotation of the mounting shaft 51, the first annular slide groove, the second annular slide groove and the ball 48 cooperate to achieve stable rotation of the structure. When the angle of the correction roller 44 is adjusted, the output end of the positioning telescopic cylinder 47 retracts, so that the ball seat 42 and the annular ball cover 49 maintain a certain distance to avoid motion interference.

[0032] For ease of cutting; such as Figure 2 , Figure 3 As shown, the cutting mechanism includes a first support frame 13, a transverse bracket 27 is mounted on the first support frame 13, a cutting blade holder 26 is provided on the transverse bracket 27, and a cutting blade 25 is mounted at the bottom of the cutting blade holder 26.

[0033] To facilitate adjustment of the cutting position; such as Figure 2 , Figure 3 As shown, a first electric telescopic cylinder 18 is installed on the first support frame 13. A slide bracket 30 is fixed to the output end of the first electric telescopic cylinder 18. Two guide slides 29 are installed on the slide bracket 30. Ball head rods 28 are fixed on both sides of the cutter frame 26. The ends of the ball head rods 28 slide on the inner wall of the guide slides 29. The distance between the two guide slides 29 is constant. The top of the guide slides 29 bends and extends to one side, and the bottom of the guide slides 29 bends and extends to the other side. The cutter frame 26 is slidably installed on the outer wall of the transverse support 27. By setting up structures such as guide slide 29 and ball head rod 28, the guide slide 29 can be raised and lowered based on the operation of the first electric telescopic cylinder 18. Since the top of the guide slide 29 bends and extends to one side and the bottom of the guide slide 29 bends and extends to the other side, the ball head rod 28 can be moved by the guide slide 29, thereby adjusting the position of the cutter holder 26 on the transverse support 27, so as to adjust the cutting position of the cutter 25.

[0034] To facilitate the smoothing of any wrinkles that may appear at the edges of the membrane material 22; such as Figure 2 , Figure 4 As shown, it also includes a smoothing mechanism, which includes a third support frame 20. A second electric telescopic cylinder 19 is installed on the third support frame 20. A roller frame 21 is installed at the output end of the second electric telescopic cylinder 19. Rollers 32 are rotatably installed on the roller frame 21 via a rotating shaft. The rollers 32 on both sides are distributed in a figure-eight shape, and their spacing gradually increases to both sides along the movement direction of the film material 22. A roller control motor 33 for controlling the rotation of the rotating shaft is installed on one side of the roller frame 21. The inclined roller 32 can rotate at a faster speed than the conveying speed of the film material 22, thus smoothing out the edge of the film material 22.

[0035] To facilitate the detection of the position and status of the membrane material 22; such as Figure 4 As shown, detection components are provided on one side of the second support frame 23 and one side of the third support frame 20. The detection components include a side bracket 31, an adjustable rod 37 is mounted on the side bracket 31, and a threaded knob 36 for fixing the adjustable rod 37 is provided on the side bracket 31. A detection frame 35 is fixed to one end of the adjustable rod 37, and a laser detection head 34 is mounted on the detection frame 35, which is more suitable for non-transparent film materials 22.

[0036] Furthermore, it can replace laser inspection with other commonly used inspection methods.

[0037] To facilitate control of the conveying tension; such as Figure 1 As shown, a tensioning mechanism is provided below the film material 22. The tensioning mechanism includes a lifting control cylinder 7. A tensioning bracket 6 is fixed to the output end of the lifting control cylinder 7. A tensioning roller 5 is rotatably mounted on the tensioning bracket 6.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
