Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a high-safety battery isolation film coating device. Background Art

[0002] The battery separator is a layer of material arranged between the positive and negative electrodes of the battery, which has a direct impact on the safety and cost of the battery. Its main function is to isolate the electrons in the positive and negative electrodes so that the electrons cannot pass through freely, and to allow the ions in the electrolyte to pass freely between the positive and negative electrodes. When producing the separator, coating equipment is required to coat the coating slurry on both sides of the separator to further improve the safety of the battery separator, thereby completing the manufacture of high-safety battery separators.

[0003] After searching, the Chinese patent application number CN202320999533.X discloses a battery separator coating device, including a base, a scraper assembly is slidably connected to the base, and also includes a slide rail assembly arranged at both ends of the base. However, after the coating process on one side of the diaphragm is completed, the diaphragm needs to be dried and turned over before the other side of the diaphragm can be coated. Therefore, there is still a problem that the two sides of the diaphragm cannot be coated continuously, resulting in low efficiency of battery separator coating. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a high-safety battery isolation film coating device.

[0014] The beneficial effects of the utility model are:

[0015] 1. The staff first lays the diaphragm to be coated on the top of the placement plate, and then clamps and fixes the two sides of the diaphragm on the clamping mechanism of the outer wall of the support rod. Then the staff pushes the movable frame back and forth to apply the coating slurry on one side of the diaphragm through the coating mechanism. Then the staff lifts the support rod and rotates it upward ninety degrees to lift the other side of the diaphragm. Then the staff controls the electric slide rail to drive the spray plate to move up and down, allowing the spray plate to spray the coating slurry to quickly spray the other side of the diaphragm, thereby continuously completing the coating process on both sides of the diaphragm and improving the efficiency of the diaphragm coating process.

[0016] 2. The staff first lifts the pressing block upwards, then places one end of the diaphragm in the U-shaped frame, and then releases the lifted pressing block, so that the pressing block clamps and fixes one end of the diaphragm placed on the inner wall of the U-shaped frame under the elastic force of the elastic telescopic rod.

[0017] 3. After the staff rotates the support rod upward 90 degrees, the limit plate on one side of the support rod will just touch the top of the L-shaped support plate, thereby limiting the support rod after it is rotated upward to the corresponding angle. At the same time, the elastic pad on the top of the L-shaped support plate can buffer the limit plate on one side to avoid hard collision between the L-shaped support plate and the limit plate.
