Description

Technical Field

[0001] This utility model relates to the field of isolation membrane processing technology, specifically a laser cutting and positioning mechanism for isolation membrane processing. Background Technology

[0002] Separator membranes are microporous or porous films, with polypropylene (PP) and polyethylene (PE) as their core materials. They are widely used in lithium-ion batteries, drilling fluids, and packaging materials. During the processing of separator membranes, traditional mechanical cutting often results in burrs, misalignment, or damage due to their thinness and susceptibility to deformation. To achieve contactless, high-precision cutting, laser cutting devices are typically used. Laser cutting devices utilize high-energy laser beams to cut and trim materials. Laser cutting enables high-precision cutting, ensuring dimensional consistency of the separator membrane, while also achieving contactless processing, avoiding contamination and damage.

[0003] When processing and cutting the release liner, the release liner is thin and easily deformed, and it is difficult to position the release liner well during the cutting process. This makes the release liner prone to displacement during the cutting process, which cannot ensure the consistency of the cutting and is not conducive to improving the cutting effect and quality. Therefore, in order to solve the above problems, a laser cutting and positioning mechanism for processing release liner is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a laser cutting and positioning mechanism for processing isolation films, so as to solve the problem mentioned in the background art that the isolation film cannot be positioned well during the cutting process, which makes the isolation film prone to displacement during the cutting process, thus failing to ensure the consistency of the cutting and thus hindering the improvement of the cutting effect and quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting and positioning mechanism for processing isolation film, comprising a table, a slide rail fixedly connected to the surface of the table, a movable frame movably connected to the surface of the slide rail, a laser cutting component movably disposed on the surface of the movable frame, a conveying roller movably connected to the inner side of the table, and a guide roller movably connected to the inner side of the table.

[0006] The surface of the movable frame is provided with a positioning mechanism, and the surface of the movable frame is provided with an adjustment mechanism;

[0007] The positioning mechanism includes a threaded rod, which is movably connected to the inner side of the movable frame. A first connecting block is threadedly connected to the surface of the threaded rod. A connecting frame is provided on the surface of the first connecting block, and a pressure roller is movably connected to the inner side of the connecting frame.

[0008] The adjustment mechanism includes a fixed frame, which is fixedly connected to the surface of the first connecting block. A positive and negative screw is movably connected to the inner side of the fixed frame, and a second connecting block is movably connected to the surface of the positive and negative screw. The connecting frame and the second connecting block are fixedly connected.

[0009] Preferably, the positioning mechanism further includes a first fixing block, which is fixedly connected to the upper surface of the movable frame, and a rotating rod is movably connected to the inner side of the first fixing block. A first conical tooth is fixedly connected to the surface of the rotating rod, and a first motor is fixedly installed on the surface of the first fixing block. The rotating rod and the output end of the first motor are fixedly connected.

[0010] Preferably, a second fixing block is fixedly connected to the inner surface of the movable frame, the threaded rod is movably connected to the second fixing block, and a second conical tooth is fixedly connected to the top end of the threaded rod.

[0011] Preferably, a slider is fixedly connected to the surface of the first connecting block, a groove is provided on the inner side of the movable frame, and the end of the slider away from the first connecting block moves within the groove.

[0012] Preferably, the adjustment mechanism further includes a second motor, the output ends of the positive and negative screws and the second motor are fixedly connected, and a limit block is fixedly connected to the surface of the second connecting block.

[0013] Preferably, the second connecting block is movable inside the fixed frame, the fixed frame has a limiting groove on its inner side, and the limiting block is movable inside the limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By rotating the first conical tooth through the rotating rod, the transmission between the first and second conical teeth can be realized. This facilitates the vertical movement of the first connecting block driven by the threaded rod, thereby enabling the lifting and lowering of the connecting frame. The lowering of the connecting frame allows the pressure roller to press and fix the isolation film, thus positioning the isolation film. This prevents the isolation film from deforming or shifting during cutting, ensuring the consistency of the isolation film cutting and improving the quality and effect of cutting.

[0017] 2. The second motor drives the positive and negative screws to rotate, which in turn moves the second connecting block and the connecting frame. This changes the position of the pressure roller. The pressure roller moves and rolls, smoothing the release film and preventing wrinkles. This results in better cutting and improved cutting quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] The first motor 23 and the second motor 32 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0027] A laser cutting and positioning mechanism for processing isolation films includes a table 1, a slide rail 11 fixedly connected to the surface of the table 1, a movable frame 12 movably connected to the surface of the slide rail 11, a laser cutting component 13 movably disposed on the surface of the movable frame 12, a conveying roller 14 movably connected to the inner side of the table 1, and a guide roller 15 movably connected to the inner side of the table 1, a positioning mechanism and an adjustment mechanism disposed on the surface of the movable frame 12, the positioning mechanism including a threaded rod 25 movably connected to the inner side of the movable frame 12, and a first connecting block 27 threadedly connected to the surface of the threaded rod 25, the surface of the first connecting block 27 being provided with a connecting... The connecting frame 210 is movably connected to the inner side of the connecting frame 210, and the adjusting mechanism includes a fixed frame 3, which is fixedly connected to the surface of the first connecting block 27. The inner side of the fixed frame 3 is movably connected to a positive and negative screw 31, and the surface of the positive and negative screw 31 is movably connected to a second connecting block 33. The connecting frame 210 and the second connecting block 33 are fixedly connected. The conveying roller 14 and the guide roller 15 can be used to convey the isolation film. The laser cutting component 13 can be used to cut the isolation film. The slide rail 11 can be used to move the moving frame 12, thereby enabling the cutting of the isolation film at different positions.

[0028] Furthermore, the positioning mechanism also includes a first fixed block 2, which is fixedly connected to the upper surface of the movable frame 12. A rotating rod 21 is movably connected to the inner side of the first fixed block 2. A first conical tooth 22 is fixedly connected to the surface of the rotating rod 21. A first motor 23 is fixedly installed on the surface of the first fixed block 2. The output ends of the rotating rod 21 and the first motor 23 are fixedly connected. The rotation of the rotating rod 21 can drive the first conical tooth 22 to rotate, thereby enabling the first conical tooth 22 to transmit power to the second conical tooth 26. This facilitates the rotation of the threaded rod 25 and causes the first connecting block 27 to drive the connecting frame 210 and the pressure roller 211 to move vertically. This allows the pressure roller 211 to move downward and contact the surface of the isolation film, thereby pressing the isolation film and achieving the effect of positioning the isolation film.

[0029] Furthermore, a second fixing block 24 is fixedly connected to the inner surface of the movable frame 12, and a threaded rod 25 is movably connected to the second fixing block 24. A second conical tooth 26 is fixedly connected to the top of the threaded rod 25. Through the setting of the threaded rod 25, when the rotating rod 21 drives the first conical tooth 22 to rotate, the second conical tooth 26 can be driven by the first conical tooth 22 and can drive the threaded rod 25 to rotate. This facilitates the first connecting block 27 to drive the connecting frame 210 to move vertically, so that the pressure roller 211 can press down on the isolation film, thereby achieving the positioning of the isolation film and making it less prone to displacement, thus ensuring the cutting effect of the isolation film.

[0030] Furthermore, a slider 28 is fixedly connected to the surface of the first connecting block 27, and a groove 29 is provided on the inner side of the movable frame 12. The end of the slider 28 away from the first connecting block 27 moves within the groove 29. By setting the slider 28 and opening the groove 29, the first connecting block 27 can be limited, which can prevent the first connecting block 27 from shifting under the action of the threaded rod 25, and facilitate the stable vertical movement of the first connecting block 27.

[0031] Furthermore, the adjustment mechanism also includes a second motor 32, with the output ends of the positive and negative screws 31 and the second motor 32 fixedly connected. A limit block 34 is fixedly connected to the surface of the second connecting block 33. By rotating the positive and negative screws 31, the second connecting block 33 can be moved, which facilitates the connecting frame 210 to drive the pressure roller 211 to move. After the pressure roller 211 presses down on the isolation film, it will roll, thereby making the isolation film flatter and facilitating the laser cutting component 13 to cut the isolation film better.

[0032] Furthermore, the second connecting block 33 is movable inside the fixed frame 3. A limiting groove 35 is provided inside the fixed frame 3, and the limiting block 34 is movable inside the limiting groove 35. By setting the limiting block 34 and opening the limiting groove 35, the second connecting block 33 can be limited, which can prevent the second connecting block 33 from shifting under the action of the positive and negative screws 31, and facilitate the second connecting block 33 to drive the connecting frame 210 to move stably.

[0033] Furthermore, the second connecting blocks 33 are movably connected to the positive and negative screws 31 in two sets, and the two sets of second connecting blocks 33 are correspondingly connected to the connecting frame 210. The pressure rollers 211 are also connected to the connecting frame 210 in two sets. By setting the second connecting blocks 33, the rotation of the positive and negative screws 31 can drive the second connecting blocks 33 to move, which facilitates the pressure rollers 211 to move accordingly, and facilitates the smoothing of the release film by moving the pressure rollers 211.

[0034] Working principle: In use, the first motor 23 is electrically connected to an external power source. The operator starts the first motor 23 by pressing the switch. The first motor 23 drives the rotating rod 21 to rotate. The first conical tooth 22 rotates under the action of the rotating rod 21 and realizes the transmission of the second conical tooth 26. Then the threaded rod 25 rotates under the action of the second conical tooth 26. The first connecting block 27 is limited by the slider 28 and the slide groove 29, which can realize the vertical movement of the first connecting block 27 under the action of the threaded rod 25, and make the slider 28 slide inside the slide groove 29. Thus, the connecting frame 210 drives the pressure roller 211 to move vertically. As the pressure roller 211 descends and contacts the isolation membrane, the isolation membrane can be pressed together, thereby realizing the positioning of the isolation membrane.

[0035] The second motor 32 is electrically connected to an external power source. The operator starts the second motor 32 by pressing a switch. The second motor 32 drives the positive and negative screws 31 to rotate. The second connecting block 33 is limited by the limiting block 34 and the limiting groove 35. Under the action of the positive and negative screws 31, it moves inside the fixed frame 3. At the same time, the limiting block 34 moves in the limiting groove 35, so that the connecting frame 210 can drive the pressure roller 211 to move accordingly. When the pressure roller 211 presses the isolation film, the pressure rollers 211 move away from each other, so that the pressure rollers 211 can smooth the isolation film and eliminate wrinkles. Then, the first connecting block 27 drives the connecting frame 210 to drive the pressure roller 211 to rise, and the second connecting block 33 drives the pressure roller 211 to move closer to each other, so that the first connecting block 27 drives the pressure roller 211 to press the isolation film again, thus achieving positioning and enabling cutting.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
