Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a solid-state battery coating machine. Background Technology

[0002] In the manufacturing process of solid-state batteries, slurry coating is the next step after slurry preparation. The main purpose of this step is to uniformly coat the positive and negative electrode current collectors with a slurry that has good stability, viscosity, and flowability. Electrode coating is of great significance to solid-state batteries.

[0003] Existing patent CN212596789U discloses a battery coating apparatus, which includes an upper die head and a lower die head connected together. The lower die head has an open-top cavity with a front sidewall opposite to the die lip of the lower die head. The cross-section of the front sidewall is arc-shaped. Therefore, by constructing the cross-section of the front sidewall as arc-shaped, when coating active material onto the current collector of the battery using the coating apparatus, the active material can be uniformly coated onto the current collector, improving the uniformity of the coating surface density, thereby improving the coating quality, ensuring the energy density of the battery, and enhancing the safety of battery use.

[0004] The above-mentioned coating machine is similar to existing equipment. Although it can uniformly coat the active material onto the current collector, it is inconvenient to control the coating thickness. Moreover, it is generally a uniform and continuous production process and cannot form multiple uniformly distributed gaps. Therefore, we propose an improved solid-state battery coating machine.

[0014] This utility model provides a solid-state battery coating machine, which has the following beneficial effects:

[0015] (1) By setting up a servo cylinder and a separating mechanism to work together, the servo cylinder can drive the separating mechanism to descend when the feeding roller is feeding. The size of the gap between the pressure plate and the feeding roller can be used to control the coating thickness of the active material. At the same time, the partition plate is elastically pressed against the surface of the feeding roller under the drive of the spring pin, so as to uniformly divide the active material, thereby facilitating the subsequent cutting operation along the gap.

[0016] (2) By setting up a liquid storage mechanism, a liquid pump, a transmission mechanism, a scraper and a receiving box to work together, the scraper can scrape off the excess coating adhering to the surface of the feeding roller and collect it in a centralized manner through the receiving box to avoid affecting the next feeding. In addition, during the feeding process, the feeding roller can drive the installation shaft to rotate through the transmission mechanism, thereby driving the stirring rod to stir the raw materials stored in the liquid storage tank, avoiding the situation where the raw materials clump together due to long production time, which would affect the feeding.
