Description

Technical Field

[0001] This utility model relates to the field of building protection netting technology, and in particular to a lithium battery preheating and baking device. Background Technology

[0002] To improve battery safety and lifespan, lithium-ion batteries coat the cathode edge with ceramic to prevent electrode edge detachment or powder shedding, maintain the integrity and stability of the cathode sheet, effectively isolate the anode and cathode, and prevent short circuits. However, the following problems exist during the coating process: the surface tension of the ceramic slurry differs significantly from that of the cathode slurry and the coating density. During the coating and drying process, the capillary effect caused by solvent evaporation can cause the ceramic slurry to cover the cathode coating area, resulting in fusion. This leads to frequent breakage at the edge during electrode rolling, insufficient battery capacity, low production line yield, and low efficiency.

[0003] In existing technologies, adjusting drying parameters to achieve high temperature and low wind frequency during wet film application, and shifting the electrode preheating and rapid evaporation stages later can optimize this phenomenon. However, as the areal density of energy storage batteries increases, it is no longer possible to solve this problem by optimizing drying parameters while ensuring both the dryness of the coating area and preventing the coating area from merging with the ceramic edge within the same oven length.

[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] Reference Figure 1-4 The present invention provides a lithium battery preheating and baking device, including a frame 1, a support plate 2 in the middle of the frame 1, a fixing rod 3 fixedly connected to the top of the frame 1, an adjustment mechanism at the bottom of the fixing rod 3, a connecting rod 8 slidably connected to the bottom of the fixing rod 3, a hot air gun 9 detachably connected to the bottom of the connecting rod 8, and a rotating locking mechanism at the top of the hot air gun 9.

[0026] First, the connecting rod 8 is moved by the adjustment mechanism, and the hot air gun 9 is moved by the moving connecting rod 8. Then, the hot air gun 9 is activated to preheat and dry the junction between the lithium battery cathode coating area and the ceramic edge placed on the support plate 2, so that a skin forms. This solves the problem of fusion caused by the high surface density of the battery and the inability to adjust the drying parameters of the short oven. In addition, if the hot air gun 9 is damaged, the connecting rod 8 can be quickly disassembled and repaired by the rotation locking mechanism, which improves the maintenance efficiency of the connecting rod 8.

[0027] The adjustment mechanism includes movable grooves 4 symmetrically opened at the bottom of the fixed rod 3. A double-headed motor 5 is provided in the middle of the inner wall of the movable groove 4. The two ends of the double-headed motor 5 are keyed to the adjustment screw 6. A screw slider 7 is movably connected to the outer contour of the adjustment screw 6. The bottom of the screw slider 7 is connected to the top of the connecting rod 8. The rotating locking mechanism includes a mounting frame 91 fixedly connected to the top of the hot air gun 9. The bottom of the connecting rod 8 is snapped into the inner wall of the mounting frame 91. A rotating shaft is provided on the outer surface of the mounting frame 91 and a rotating plate 10 is rotatably connected to it through the rotating shaft. A locking element is provided on the surface of the rotating plate 10.

[0028] By activating the dual-head motor 5 in the active slot 4, the dual-head motor 5 drives the adjusting screw 6 to rotate, which in turn drives the screw sliders 7 on the two adjusting screws 6 to move closer to each other or move. In turn, the screw sliders 7 drive the hot air gun 9 at the bottom of the connecting rod 8 to move. Then, the temperature control box set on the side of the frame 1 is activated to adjust the temperature of the hot air gun 9 during use. Then, the hot air gun 9 is used to preheat and dry the junction between the lithium battery cathode coating area and the ceramic edge placed on the support plate 2. If the hot air gun 9 is damaged, the locking device on the rotating plate 10 can be used to release the locking limit of the connecting rod 8 that is stuck in the mounting frame 91. Then, the hot air gun 9 can be disassembled, and then the staff can replace or repair it, which further increases the practicality of the equipment.

[0029] The locking component includes a fixed sleeve 11 fixedly connected to the surface of the rotating plate 10. A movable block 12 is provided at one end of the fixed sleeve 11. A hexagonal limiting rod 13 is fixedly connected to the end of the movable block 12 near the inner wall of the fixed sleeve 11. A stop block 16 is fixedly connected to the end of the outer contour of the hexagonal limiting rod 13 away from the movable block 12. A return spring 14 that is sleeved with the hexagonal limiting rod 13 is provided on the stop block 16. A connecting block 15 is detachably connected to the side of the inner wall of the fixed sleeve 11 near the movable block 12. A limiting hole that matches the hexagonal limiting rod 13 is opened on the surface of the connecting rod 8 near the bottom. An anti-slip sleeve 17 is sleeved on the outer contour of the movable block 12. An anti-slip protrusion is provided on the outer surface of the anti-slip sleeve 17. An external thread is opened on the outer contour of the connecting block 15. An internal thread that matches the external thread is opened on the side of the inner wall of the fixed sleeve 11 near the connecting block 15.

[0030] Pulling the movable block 12 moves the hexagonal limit rod 13 outward, causing it to move out of the limiting hole on the connecting rod 8. Then, the operator rotates the rotating plate 10 upward, allowing the hot air gun 9 to be removed from the bottom of the connecting rod 8 for replacement or repair. When installing the connecting rod 8, the mounting frame 91 at the top of the hot air gun 9 is engaged with the bottom of the connecting rod 8. The operator then pulls the movable block 12 outward again, moving the hexagonal limit rod 13. The hexagonal limit rod 13 moves the stop block 16, which in turn presses against the return spring 14. When the hexagonal limit rod 13 is fully inserted into the fixed sleeve 11, the rotating plate 10 and the movable block 12 can be moved towards the installation... The limiting holes on frame 91 and connecting rod 8 move. When the hexagonal limiting rod 13 moves to the limiting hole, the movable block 12 can be released. Then, the compressed return spring 14 drives the stop block 16 and the hexagonal limiting rod 13 to reset. The hexagonal limiting rod 13 is then engaged into the limiting hole, thus completing the installation of the hot air gun 9. When the return spring 14 is damaged, the operator rotates the movable block 12 to rotate the hexagonal limiting rod 13, causing the hexagonal limiting rod 13 to drive the connecting block 15 to rotate. The hexagonal limiting rod 13, return spring 14, connecting block 15, and stop block 16 are then removed from the fixed sleeve 11, and the return spring 14 can be replaced. The anti-slip effect is increased by the anti-slip sleeve 17 and the anti-slip protrusions on its outer contour.

[0031] Working principle: First, start the double-headed motor 5 in the movable slot 4. The double-headed motor 5 drives the adjusting screw 6 to rotate, which in turn drives the screw sliders 7 on the two adjusting screws 6 to move closer to each other or move. Then, the screw sliders 7 drive the hot air gun 9 at the bottom of the connecting rod 8 to move. Then, start the temperature control box set on the side of the frame 1 to adjust the temperature of the hot air gun 9 when in use. Then, use the hot air gun 9 to preheat and dry the junction between the lithium battery cathode coating area and the ceramic edge placed on the support plate 2.

[0032] Pulling the movable block 12 moves the hexagonal limit rod 13 outward, causing it to move out of the limiting hole on the connecting rod 8. Then, the operator rotates the rotating plate 10 upward, allowing the hot air gun 9 to be removed from the bottom of the connecting rod 8 for replacement or repair. When installing the connecting rod 8, the mounting frame 91 at the top of the hot air gun 9 is engaged with the bottom of the connecting rod 8. The operator then pulls the movable block 12 outward again, moving the hexagonal limit rod 13. The hexagonal limit rod 13 moves the stop block 16, which in turn presses against the return spring 14. When the hexagonal limit rod 13 is fully inserted into the fixed sleeve 11, the hot air gun 9 can be removed. The rotating plate 10 and the movable block 12 move toward the limiting holes opened on the mounting frame 91 and the connecting rod 8. When the hexagonal limiting rod 13 moves to the limiting hole, the movable block 12 can be released. Then, the compressed return spring 14 drives the stop block 16 and the hexagonal limiting rod 13 to reset, and the hexagonal limiting rod 13 is snapped into the limiting hole. At this time, the installation of the hot air gun 9 is completed. When the return spring 14 is damaged, the operator rotates the movable block 12 to drive the hexagonal limiting rod 13 to rotate, so that the hexagonal limiting rod 13 drives the connecting block 15 to rotate. The hexagonal limiting rod 13, the return spring 14, the connecting block 15 and the stop block 16 are removed from the fixed sleeve 11, and the return spring 14 can be replaced.
