Description

Technical Field

[0001] The present invention relates to the technical field of battery processing and cleaning, and specifically to a die head oil fume control structure. Background Art

[0002] A prior art document with the publication number CN114472261A discloses a dust removal device for hot pressing the battery core of a secondary battery. Its solution includes a bracket, a first driving mechanism, and an air knife mechanism. The bracket is used to install the first driving mechanism and fix itself at appropriate positions outside each hot pressing chamber of the battery core hot pressing device. The air knife mechanism is slidably connected to the movable end of the first driving mechanism, and the first driving mechanism can drive the air knife mechanism into and return from the hot pressing chamber. During the movement of the scraper in the air knife mechanism in the hot pressing chamber, it always closely adheres to the surfaces of the upper hot pressing plate and the lower hot pressing plate and maintains a vertical pressure on the battery core contact surface on the plate surface, capable of scraping off the dust adhered to the battery core contact surface, and all the dust can be synchronously sucked away through the air cylinder in the air knife mechanism, avoiding the pollution of subsequent battery cores and the pollution of the battery core hot pressing device and the surrounding environmental space.

[0003] In the prior art, after the battery core is wound or laminated and assembled, the bare battery core needs to be hot pressed to shape the electrode sheet and the separator, making the two contact more closely and reducing the lithium ion transmission resistance; during hot pressing, an insulation withstand voltage test is often performed on the bare battery core to mainly judge whether there are foreign particles inside the battery core causing a short circuit; during the processing process, the lack of good control over the die head oil fume will cause the oil fume to form oil droplets when the die head cools, dripping onto the surface of the sheet material and having a greater impact on the thickness uniformity and residual oil rate of the separator, thereby affecting the HIPOT of the wound or laminated battery core of the separator.

[0004] Among the existing solutions, generally, a blowing device and a smoking hood device are added on both sides of the die head respectively to suck away the oil gas and small molecular weight gases generated during the production process and prevent them from aggregating into oil droplets when the die head cools; a blowing device and a smoking hood device are arranged on the side of the die head processing position for combined use, with the smoking hood device as the main and the blowing device as the auxiliary, and the two are used in combination to avoid the accumulation and cooling of oil fume on the die head; however, during this process, the oil gas will also accumulate on the smoking hood device, especially adhering and accumulating on the inner side wall of the smoking hood. It lacks a corresponding cleaning component to clean it, which not only has a negative impact on the subsequent oil fume discharge work, but also the adhered oil fume will cool and drip, posing a threat to the product processing quality; further improvement and optimization are needed.

[0005] Therefore, the present invention proposes a die head oil fume control structure to solve the above problems. Summary of the Invention
