Technical Field
[0001] This utility model relates to the field of lithium-ion batteries, specifically to a lithium-ion battery coating machine. Background Technology
[0002] The main function of a lithium-ion battery coating machine is to precisely and uniformly coat a slurry containing active materials (such as positive and negative electrode materials), conductive agents, and binders onto a battery electrode substrate (usually copper or aluminum foil) during continuous operation, forming an electrode coating with a certain thickness and mass distribution. In existing technologies, lithium-ion battery coating machines require the current collector to be transported in a straight line for coating and drying sequentially. This results in a relatively long overall length of the machine, leading to a large footprint. Furthermore, the coating and drying processes generate harmful gases, affecting the working environment and worker health.

A storage frame 6 is installed at the bottom inside the packaging box 1, and a coating roller 7 is provided inside the storage frame 6, rotatably connected to the inner wall of the packaging box 1. Several conveying rollers 8 are provided inside the packaging box 1. A take-up shaft 9 is rotatably connected to the front wall of the packaging box 1. A motor 10 is installed at the front end of the take-up shaft 9. Limiting rods 11 are symmetrically installed on the side of the take-up shaft 9. A take-up drum 12 is sleeved on the outer surface of the take-up shaft 9, and limiting slots 13 are symmetrically provided on the inner wall of the take-up drum 12. Several heating tubes 14 are installed on the inner wall of the packaging box 1. A fixing pipe 15 is installed at the upper end of the packaging box 1, and a fan 16 is installed at the upper end of the fixing pipe 15. The purification mechanism 17 is installed. Suction rods 28 are symmetrically arranged on the left side of the inlet 4. A suction fan 29 is installed at the front end of both suction rods 28, and the suction fan 29 is connected to the lower end of the purification mechanism 17. The purification mechanism 17 includes a purification frame 18 and activated carbon filter plates 19. Several activated carbon filter plates 19 are arranged inside the purification frame 18. Pull plates 20 are installed at the rear ends of the activated carbon filter plates 19. A snap-fit mechanism 21 is symmetrically installed at the rear ends of the pull plates 20, and the pull plates 20 are fixedly connected to the purification frame 18 through the snap-fit mechanism 21. The snap-fit mechanism 21 includes a sliding groove 22 and a fixing block 26. The sliding groove 22 is symmetrically opened at the rear ends of the pull plates 20. Guide blocks are symmetrically installed on the inner wall of the sliding groove 22. A snap-fit block 23 is slidably connected inside the sliding groove 22. A spring 24 is installed at one end of the snap-fit block 23, and a locking block 25 is installed at the other end of the snap-fit block 23. The fixing block 26 is symmetrically fixed at the rear ends of the purification frame 18, and a locking hole 27 is opened inside the fixing block 26.
[0021] The working principle of this utility model is as follows: Multiple activated carbon filter plates 19 are installed inside the purification frame 18. The spring 24 pushes the latching block 23 to move, and the latching block 23 drives the locking block 25 to be inserted into the locking hole 27, so that the activated carbon filter plates 19 are installed inside the purification frame 18. The pull door 3 is opened and the take-up drum 12 is sleeved on the take-up shaft 9, so that the limiting rod 11 is inserted into the limiting slot 13. Then, one end of the collector is passed through the inlet 4, between the two mating rollers 5, the upper end of the coating roller 7 and the outer surface of several conveying rollers 8 in sequence and wound around them. Outside the take-up drum 12, the current collector is arranged in a square spiral shape inside the packaging box 1. The current collector is coated by the coating roller 7 and conveyed by multiple conveying rollers 8, so that the coated end of the current collector always faces outward. Then, the current collector is dried by multiple heating tubes 14, resulting in good drying effect. Then, the motor 10 drives the take-up shaft 9 to rotate. The take-up shaft 9 drives the take-up drum 12 to rotate through the limiting rod 11 and the limiting slot 13, and the dried current collector is wound up by the take-up drum 12.
[0022] The collector is conveyed and wound in a square spiral shape, which reduces the footprint of the collector and the packaging box 1, saving factory space. Harmful gases are generated during the coating and drying of the collector. The harmful gases in the packaging box 1 are drawn into the purification mechanism 17 by the fan 16. At the same time, the suction fan 29 and the suction rod 28 draw air from the inlet 4 and transfer it into the purification mechanism 17 to prevent the harmful gases from being discharged through the inlet 4. Then, the harmful gases are purified by multiple activated carbon filter plates 19 to ensure the working environment and the health of the workers.
