Description

Technical Field

[0001] This utility model relates to the field of winding technology, specifically a winding mechanism for a gel lithium battery separator. Background Technology

[0002] A battery separator is a high-strength, thin-film polyolefin porous membrane used to separate the positive and negative electrodes of a battery, preventing short circuits at the junction of the positive and negative electrodes. The surface of the battery separator has a large number of micropores, which allow electrolyte ions to pass through the separator, thereby forming a charging and discharging circuit.

[0003] Currently, the winding mechanism of existing gel lithium battery separators typically uses a motor to drive the core to rotate and wind the separator. During use, the separator production machine must be stopped for replacement, and the core must be repeatedly disassembled and reassembled after winding, significantly reducing the winding efficiency of the battery separator. Furthermore, when using the separator, which is often too wide, it is cut into suitable widths. During the cutting process of lithium-ion separators, edge curling occurs, affecting the subsequent core winding process. This edge curling also impacts the winding effect. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example

[0027] Please see Figures 1 to 6 The present invention provides a technical solution including a movable plate 1, a connecting plate 6 fixedly connected to the upper part of the movable plate 1, a support shaft 17 connected to the internal bearing of the connecting plate 6, a servo motor 5 connected to the output shaft key at one end of the support shaft 17, a movable frame 12 slidably connected to the upper part of the movable plate 1, the inside of the movable frame 12 being fitted around the end of the support shaft 17 away from the servo motor 5, a core 8 being inserted into the outside of the support shaft 17, and a diaphragm roll 7 being wound around the outside of the core 8.

[0028] A limiting cover 10 is provided at the lower part of the connecting plate 6. The inner side of the limiting cover 10 contacts the diaphragm roll 7. A base 2 is slidably connected to the lower part of the movable plate 1. A limiting block 16 is fixedly connected to the upper part of the base 2. A plug rod 14 is inserted into the inside of the limiting block 16. An insertion hole 13 is opened at the upper part of the movable plate 1. The lower part of the plug rod 14 is inserted into the inside of the insertion hole 13.

[0029] Specifically, the limiting cover 10 is a semi-circular plate, located below the support shaft 17, and the length of the limiting cover 10 is greater than the length of the support shaft 17.

[0030] A support frame 3 is fixedly connected to one side of the movable plate 1. A support block 20 is fixedly connected to the upper part of the support frame 3. A movable groove 21 is opened on one side of the support block 20. A support rod 15 is installed inside the movable groove 21. A rolling roller 4 is fixedly connected to one end of the support rod 15. The lower part of the rolling roller 4 contacts the upper part of the support frame 3.

[0031] Specifically, the rolling roller 4 is relatively heavy, and it can be moved through the movable groove 21.

[0032] Please refer to Figure 1 to Figure 3 The sockets 13 are arranged in a linear array, and the spacing between the sockets 13 is the length of the core 8. Multiple cores 8 are sleeved on the outside of the support shaft 17.

[0033] Specifically, each socket 13 corresponds to a winding core 8.

[0034] Please refer to Figure 2 to Figure 5 The support shaft 17 has a top block 9 slidably connected inside. The end of the support shaft 17 away from the servo motor 5 is rotatably connected to a fixing block 11. The outer side of the fixing block 11 supports the top block 9, and the outer side of the top block 9 contacts the core 8.

[0035] Specifically, the outer side of the fixing block 11 has a continuous concave-convex shape, and the top block 9 supports and fixes multiple cores 8.

[0036] Please see Figure 2 Figure 5 to Figure 6 A dual-axis motor 18 is fixedly connected to the lower side of the upper part of the support frame 3. One end of the dual-axis motor 18 is connected to a cutting circular blade 19 via an output shaft key. The upper part of the cutting circular blade 19 extends out of the support frame 3.

[0037] Specifically, the cutting circular blade 19 cuts the edge of the rolled film.

[0038] Please see Figure 2 Figure 5 to Figure 6 The upper part of the support frame 3 is provided with two rolling rollers 4, and the cutting circular blade 19 is located in the middle of the two rolling rollers 4. The distance between the two cutting circular blades 19 is the length of the core 8.

[0039] Specifically, two rolling rollers 4 press and restrict the diaphragm, and the auxiliary cutting circular knife 19 cuts the material that exceeds the length of the core 8.

[0040] Please refer to Figure 1 to Figure 4 A groove is provided on one side of the movable frame 12, and one side of the limiting cover 10 is inserted into the groove of the movable frame 12. The other side of the limiting cover 10 is connected to the connecting plate 6 by a pull rod.

[0041] Specifically, the movable frame 12 supports the limiting cover 10 through the groove and is limited by the pull rod of the limiting cover 10.

[0042] In use, multiple roll cores 8 are successively fitted onto the support shaft 17. Then, the movable frame 12 is pushed so that its upper part is also fitted onto the end of the support shaft 17. Using an Allen wrench, the fixing block 11 is rotated, causing the top block 9 to move outward through the protrusion of the fixing block 11, thus supporting and fixing the roll cores 8. Through the arrangement of the support shaft 17, movable plate 1, base 2, and movable frame 12, multiple roll cores 8 can be placed. When the movable frame 12 moves, the limiting cover 10 is lifted upward, with one side of the limiting cover 10 contacting the connecting plate 6. The other side of the limiting cover 10 is inserted into the groove of the movable frame 12 through the moving frame, fixing the limiting cover 10. The servo motor 5 is started to drive the support shaft 17, which drives the roll cores 8 to rotate, winding up the film. The wound film forms a diaphragm roll 7. After the diaphragm roll 7 is wound up, the diaphragm roll 7... The outermost layer contacts the limiting cover 10, which supports and restricts the diaphragm roll 7 to prevent it from gradually unwinding as the support shaft 17 rotates. Through the movable frame 12 and the limiting cover 10, the wound diaphragm roll 7 is restricted. After one diaphragm roll 7 is wound up, the movable plate 1 is pushed to move on the base 2, so that the insertion rod 14 moves from the current insertion hole 13 to the next insertion hole 13 and inserts into the insertion hole 13, fixing the movable plate 1 to the base 2. The movement of the movable plate 1 causes the core 8 to move as well, moving the unwound core 8 to the film position for winding. Through the cooperation of the insertion hole 13, the insertion rod 14 and the limiting block 16, the movement distance of the movable plate 1 can be limited during use, thereby switching between different cores 8 and improving winding efficiency.

[0043] During winding, the film is passed between the pressing roller 4 and the upper part of the support frame 3. When passing through, the pressing roller 4 is pulled upward, and the support rod 15 moves within the movable groove 21 to facilitate the passage of the film. When winding through the support shaft 17, the film is pulled, and the pressing roller 4 presses down any warped edges. The arrangement of the support frame 3, support rod 15, support block 20, and pressing roller 4 achieves the effect of flattening the diaphragm. The cutting circular blade 19 driven by the dual-axis motor 18 cuts off the burrs and excess material on the edge of the film, keeping the diaphragm roll 7 neatly wound. Through the coordinated arrangement of the cutting circular blade 19 and the dual-axis motor 18, the burrs and excess material on the edge of the diaphragm can be cut during use, thereby facilitating winding and reducing film warping.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
