Description

Technical Field

[0001] The utility model belongs to the technical field of protective film production, and in particular to a production device for UV anti-sticking protective films. Background Technique

[0002] UV anti-sticking film is a thin film material manufactured using ultraviolet (UV) light curing technology, which is used to form a protective film on the product surface or provide specific functions. It has a wide range of applications in fields such as wafer cutting and semiconductor cutting.

[0003] After retrieval, it is found that for the UV anti-sticking protective film production device with Chinese publication number: CN216884283U, the excess waste materials on both sides of the raw material are cut by a blade. Then, the waste materials generated after cutting will slowly move along with the guiding of the inclined surface of the triangular inclined block and the pushing of the subsequent raw material and waste materials, and finally fall into the interior of the recycling box, thus completing the recycling work of the waste materials, thereby reducing the later work difficulty of the cleaning staff. When moving on the surface of the workbench, the limiting roller rotates through the movement of the raw material to assist the raw material in moving, and also presses and positions the raw material, so that the raw material will not wrinkle when the blade cuts both sides of the raw material, better protecting the raw material, and thus improving the quality of the raw material.

[0004] Obviously, we can see that the effective effect of the above device lies in guiding the waste materials after slitting through the triangular inclined block, and then collecting them. Then, through devices such as limiting rollers, the raw material is smoothed to reduce the occurrence of wrinkles. However, the above device will have the following problems in actual application:

[0005] When the above device actually guides the waste materials after slitting, it does not consider that in actual situations, there is inevitably adhesion between the waste materials of the UV anti-sticking protective film after slitting or there is static adsorption between them. As a result, the waste materials after slitting will inevitably accumulate together, and it is inevitable that the waste materials will accumulate too quickly, occupy a large volume, and are not convenient for large-capacity storage. Or, due to the adsorption between the waste materials, the waste materials will block the interior of the above device, affecting the slitting process.

[0006] When the above device actually presses the UV anti-sticking protective film, for the UV anti-sticking protective film with small folding angles, it can be smoothed through pressing. Then, when facing some bends with angles exceeding 90 degrees, if the pressing process is directly carried out at this time, the bent part exceeding 90 degrees will be pressed on other UV anti-sticking protective films, inevitably affecting the slitting process of the UV anti-sticking protective film and resulting in an impact on the processing process.

[0007] The above problems are problems that occur or exist in the prior art. In order to address the deficiencies in the prior art, we propose a production device for UV anti-sticking protective films. Summary of the Utility Model

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0030] Please refer to Figures 1 to 6 , an embodiment of the present utility model provides a production device for a UV anti-sticking protective film, including a mounting plate 1, an unwinding roller 2 rotatably arranged on one side of the mounting plate 1 for placing the UV anti-sticking protective film, a plurality of slitting blades 21 for cutting the UV anti-sticking protective film are arranged inside the mounting plate 1, and a winding mechanism I and a winding mechanism II for winding the UV anti-sticking protective film are arranged on the side of the slitting blade 21 away from the unwinding roller 2;

[0031] The coiling mechanism I includes a secondary coiling roller 26 and a second motor 27. The secondary coiling roller 26 is rotatably arranged on the inner wall of the mounting plate 1. The second motor 27 is installed on the outer wall of the mounting plate 1, and the output end of the second motor 27 extends into the mounting plate 1 and is connected to the secondary coiling roller 26;

[0032] The coiling mechanism II includes a fixing plate 23, a primary coiling roller 24 and a first motor 25. A plurality of fixing plates 23 are arranged on one side of the secondary coiling roller 26. Specifically, there are two fixing plates 23, and the two fixing plates 23 are arranged in a mirror image based on the middle cross-section of two opposite inner walls of the mounting plate 1 or two opposite outer walls of the secondary coiling roller 26. The primary coiling roller 24 is rotatably arranged on the outer wall of the fixing plate 23. The first motor 25 is installed on the outer wall of the primary coiling roller 24 away from the fixing plate 23, and the output end of the first motor 25 extends into the inner side of the fixing plate 23 and is connected to the primary coiling roller 24. Combining the above description, it can be seen that the primary coiling roller 24, the first motor 25 and the fixing plate 23 are all arranged symmetrically in a mirror image along one of the middle cross-sections;

[0033] There are two sets of coiling mechanisms II and one set of coiling mechanism I. The two sets of coiling mechanisms II are arranged in parallel. At the same time, there is a height level difference between the two sets of coiling mechanisms II and the coiling mechanism I. During use, the UV release protective film can be placed through the unwinding roller 2, and the installed UV release protective film to be processed can be slit by the slitting blade 21. Moreover, the horizontal height difference between the coiling mechanism II and the coiling mechanism I allows the slit UV release protective film to pass through the gap existing between the two coiling mechanisms II and the coiling mechanism I. Then, by starting the first motor 25, the primary coiling roller 24 can be driven to rotate, and by starting the second motor 27, the secondary coiling roller 26 can be driven to rotate, so as to complete the coiling of the three parts of the slit UV release protective film, thereby avoiding the situation of winding or accumulation of the waste of the slit UV release protective film or the processed material, which is convenient for subsequent reprocessing or treatment process.

[0034] Please refer to Figures 1 to 6, an adjusting mechanism for adjusting the relative positions of the plurality of slitting blades 21 and the fixing plate 23 is connected to the slitting blade 21. The adjusting mechanism includes a bidirectional screw rod II 18, a limiting slide bar 19, and a sliding mounting block 20. The bidirectional screw rod II 18 is rotatably arranged on the inner wall of the mounting plate 1. The limiting slide bar 19 is arranged on one side of the bidirectional screw rod II 18, and both ends of the limiting slide bar 19 are connected to the inner wall of the mounting plate 1. A plurality of sliding mounting blocks 20 are distributed and connected to the outer walls of the bidirectional screw rod II 18 and the limiting slide bar 19. The sliding mounting block 20 is screwed to the bidirectional screw rod II, and at the same time, the sliding mounting block 20 is slidably connected to the limiting slide bar 19. A connecting plate 22 is connected to the outer wall of one side of the sliding mounting block 20. One end of the connecting plate 22 away from the sliding mounting block 20 is connected to the fixing plate 23. The sliding mounting block 20 is used for installing and fixing the slitting blade 21. Specifically, the slitting blade 21 is fixedly connected to the sliding mounting block 20 by bolts. Therefore, the slitting blade 21 can be replaced or cleaned by removing the bolts. When in use, by rotating the bidirectional screw rod II 18, the two groups of sliding mounting blocks 20 on the bidirectional screw rod II can move away from or close to each other in cooperation with the limiting slide bar 19. Moreover, when the sliding mounting block 20 moves, since the sliding mounting block 20 and the fixing plate 23 are connected by the connecting plate 22, when the sliding mounting block 20 moves, the fixing plate 23 can be driven to move synchronously through the connecting plate 22. Thus, when adjusting the spacing of the slitting blade 21 by rotating the bidirectional screw rod II to change the corner slitting position of the UV adhesive-reducing protective film, the position of the first winding roller 24 can be adjusted at the same time, so that the spacing of the first winding roller 24 inside the mounting plate 1 conforms to the size of the corners of the UV adhesive-reducing protective film to be wound. In this way, under the condition of meeting the winding requirements of the first winding roller 24, the space occupied by the first winding roller 24 inside the mounting plate 1 can be reduced as much as possible.

[0035] Please refer to Figures 1 to 6 , a guiding mechanism for guiding the movement of the UV adhesive-reducing protective film is arranged on the side of the slitting blade 21 away from the first winding mechanism or the second winding mechanism. The guiding mechanism includes guiding rollers 3. A plurality of guiding rollers 3 are connected to the inner wall of the mounting plate 1. Specifically, two groups of guiding rollers 3 are provided, and the two groups of guiding rollers 3 are arranged in parallel. After the UV adhesive-reducing protective film is placed on the mounting plate 1, it is wound through the two groups of parallel guiding rollers 3 in sequence, and then passes through the two groups of second winding mechanisms and the first winding mechanism in sequence. The settings of the second motor 27 and the first motor 25 can provide the force required for the movement of the UV adhesive-reducing protective film, and the guiding rollers 3 can guide the UV adhesive-reducing protective film horizontally. Thus, the guiding, slitting, and winding of different parts of the UV adhesive-reducing protective film are completed.

[0036] Please refer to Figures 1 to 6, an adjustable flattening mechanism for flattening the UV anti-sticking protective film during guiding is arranged on the upper side of the guiding mechanism. The adjustable flattening mechanism comprises a bidirectional screw rod 17, a movable block 16, a flattening roller 14, a flattening roller 9, a connecting block 10, a mounting connecting plate 13 and a guiding slide bar 15. The bidirectional screw rod 17 is rotatably arranged on the inner wall of the mounting plate 1. A plurality of movable blocks 16 are screwed on the outer wall of the bidirectional screw rod 17. The flattening roller 14 is rotatably connected to the outer wall of one group of the movable blocks 16. The flattening roller 9 is rotatably connected to the outer wall of the other group of the movable blocks 16. The guiding slide bar 15 is fixedly arranged on the inner wall of the mounting plate 1. The mounting connecting plate 13 is connected to the end of the flattening roller 14 away from the movable block 16. A plurality of connecting blocks 10 are distributed and slidably arranged on the outer wall of the guiding slide bar 15, and the plurality of connecting blocks 10 are respectively connected to the mounting connecting plate 13 or the flattening roller 9. Moreover, the connecting block 10 connected to the flattening roller 9 allows the flattening roller 9 to rotate while limiting the position of the flattening roller 9. Through the above structure, by rotating the bidirectional screw rod 17 clockwise or counterclockwise, in cooperation with the guiding slide bar 15, the connecting block 10 and the mounting connecting plate 13, the flattening roller 9 and the flattening roller 14 can move away from or close to each other, so that the flattening roller 9 and the flattening roller 14 can be adjusted according to the specifications of the UV anti-sticking protective film actually placed on the feeding roller 2.

[0037] Please refer to Figures 1 to 6, a driven mechanism for driving the worm wheel 8 to rotate is connected to one set of the guide rollers 3. The driven mechanism includes a mounting rod 6, a driving wheel 4, a driven wheel 5, a worm 7 and a worm wheel 8. The mounting rod 6 is rotatably arranged on the inner wall of the mounting plate 1. The driving wheel 4 is arranged on the outer wall of one set of the guide rollers 3. The driven wheel 5 is arranged on the outer wall of the mounting rod 6, and the driven wheel 5 is connected to the driving wheel 4 through a crawler. A plurality of worms 7 are distributed and fixedly connected to the outer wall of the mounting rod 6 by bolts. A plurality of worm wheels 8 are arranged and meshed with the worms 7. After one set of the guide rollers 3 rotates, the crawler arranged between the driving wheel 4 and the driven wheel 5 can drive the mounting rod 6 to rotate synchronously. When the mounting rod 6 rotates, the worm 7 fixedly connected to the mounting rod 6 by bolts will also rotate accordingly, so as to drive the worm wheel 8 meshed with the worm 7 to rotate, thereby completing the driving process of the worm wheel 8 and making the worm wheel 8 rotate synchronously. One set of the worm wheels 8 is connected to the flattening roller 1 9. Through this set of worm wheels 8 connected to the flattening roller 1 9, the flattening roller 1 9 can be directly driven to rotate. At one end of the other set of the worm wheels 8, a reverse rotation mechanism for reversely driving the flattening roller 2 14 to rotate is connected. The reverse rotation mechanism includes a gear 1 11 and a gear 2 12. The gear 1 11 is connected to the mounting connecting plate 13, and one end of the gear 1 11 extends to one side of the mounting connecting plate 13 and is connected to one set of the worm wheels 8. The gear 2 12 is sleeved on one end of the flattening roller 2 14, and the gear 2 12 is meshed with the gear 1 11. After the worm wheel 8 connected to the gear 1 11 rotates, the gear 1 11 will also rotate, so as to drive the gear 2 12 to rotate. At this time, the rotation direction of the gear 2 12 is opposite to the rotation direction of the other set of worm wheels 8 connected to the flattening roller 1 9, so that the rotation direction of the flattening roller 2 14 is opposite to that of the flattening roller 1 9. At this time, the rotation modes of both the flattening roller 1 9 and the flattening roller 2 14 are from the inner side of the mounting plate 1 to the outer side of the mounting plate 1, which is convenient for bending and flattening the UV anti-adhesive protective film transported on the guide rollers 3 by the flattening roller 1 9 and the flattening roller 2 14, and the flattening process is not limited by the bending angle of the UV anti-adhesive protective film. When reaching the plane of the guide rollers 3, the guide rollers 3 support the UV anti-adhesive protective film, so as to avoid over-flattening, that is, after ensuring that the UV anti-adhesive protective film is completely flattened, it will not be wound into the flattening roller 1 9 or the flattening roller 2 14. Through the above process, the situation that the slitting process is affected due to the bent part of the UV anti-adhesive protective film is reduced, thereby improving the slitting efficiency and having strong practicability.

[0038] In summary, during the processing and slitting of the UV adhesive - reducing protective film by this device, first, the guiding and winding processes of the UV adhesive - reducing protective film are completed through the unwinding roller 2, guiding roller 3, winding mechanism two, and winding mechanism one. Then, through the connecting plate 22, the waste materials on both sides of the UV adhesive - reducing protective film can be cut off, so as to better cooperate with the process of separating different parts of the UV adhesive - reducing protective film into rolls;

[0039] In addition, this device can rotate the bidirectional screw two 18, and cooperate with the limit slide bar 19 to make the two sets of sliding mounting blocks 20 on the bidirectional screw two 18 move away from or close to each other. Through the connecting plate 22, the fixed plate 23 can be driven to move synchronously. When adjusting the distance between the slitting blades 21 by rotating the bidirectional screw two 18 to change the corner slitting position of the UV adhesive - reducing protective film, the position of the first winding roller 24 can be adjusted simultaneously, so that the distance between the first winding roller 24 inside the mounting plate 1 conforms to the size of the corners of the UV adhesive - reducing protective film to be wound. At the same time, by rotating the bidirectional screw one 17 clockwise or counterclockwise, it can cooperate with the guide slide bar 15, connecting block 10, and mounting connecting plate 13 to make the first flattening roller 9 and the second flattening roller 14 move away from or close to each other, so that the first flattening roller 9 and the second flattening roller 14 can be adjusted according to the specifications of the actual UV adhesive - reducing protective film placed on the unwinding roller 2. The driving of the first flattening roller 9 and the second flattening roller 14 can be completed through the reverse mechanism composed of the first gear 11 and the second gear 12 and the driven mechanism composed of the mounting rod 6, driving wheel 4, driven wheel 5, worm 7, and worm gear 8, and the driving methods are all from the inside out.

[0040] It can be seen from the above process that this device can complete the unwinding, slitting, and winding processes of the UV adhesive - reducing protective film through the unwinding roller 2, guiding roller 3, winding mechanism two, and winding mechanism one, in cooperation with the bidirectional screw two 18, limit slide bar 19, sliding mounting blocks 20, and connecting plate 22. And the slitting and side - material winding are adjusted synchronously, with a wide range of applications. Through the adjustable flattening mechanism composed of the bidirectional screw one 17, movable block 16, second flattening roller 14, first flattening roller 9, connecting block 10, mounting connecting plate 13, and guide slide bar 15, in cooperation with the reverse mechanism composed of the first gear 11 and the second gear 12 and the driven mechanism composed of the mounting rod 6, driving wheel 4, driven wheel 5, worm 7, and worm gear 8 to drive the first flattening roller 9 and the second flattening roller 14 from the inside out, when the UV adhesive - reducing protective film is guided by the guiding roller 3, the corners of the UV adhesive - reducing protective film can be flattened, reducing the slitting errors caused by large bending parts of the UV adhesive - reducing protective film, thereby improving the slitting efficiency and slitting accuracy.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present utility model shall be included within the protection scope of the present utility model.
