Description

Technical Field

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

[0002] The existing document with announcement number CN114472261A discloses a dust removal device for hot pressing of battery cells of secondary batteries, and its scheme includes a bracket, a first driving mechanism and a wind knife mechanism. The bracket is used to install the first driving mechanism and to fix itself at a suitable position outside each hot pressing chamber of the battery cell hot pressing device. The wind knife mechanism is slidably connected to the movable end of the first driving mechanism, and the first driving mechanism can drive the wind knife mechanism to enter the hot pressing chamber and return. During the movement of the scraper in the wind knife mechanism in the hot pressing chamber, it always clings to the plate surface of the upper hot pressing plate and the lower hot pressing plate and maintains vertical pressure on the battery cell contact surface on the plate surface, which can scrape away the dust adhering to the battery cell contact surface, and the wind tube in the wind knife mechanism can synchronously suck away all the dust, so as to avoid dust pollution to subsequent battery cells and pollution to the battery cell hot pressing device and the surrounding space.

[0003] In the prior art, after the battery core is wound or stacked, the bare cell needs to be hot-pressed to shape the electrode and diaphragm so that the two are in closer contact and the resistance to lithium ion transmission is reduced. During the hot-pressing process, the bare cell is often subjected to an insulation withstand voltage test, mainly to determine whether there are foreign particles inside the cell that cause a short circuit. During the processing, the lack of good control of the die fume will cause the fume to form oil droplets when the die is cooled, and drip onto the surface of the sheet, which has a significant impact on the thickness uniformity and residual oil rate of the diaphragm, thereby affecting the HIPOT of the diaphragm winding or stacked cell.

[0004] Among them, the existing solutions generally include adding blowing and fume hood devices on both sides of the die head to extract the oil gas and small molecular weight gas generated during the production process to prevent them from gathering into oil droplets when the die head is cooled; setting a blowing device and a fume hood device on the side of the die head processing position for coordinated use, with the fume hood device as the main device and the blowing device as the auxiliary device, and the two are used in combination to avoid the accumulation and cooling of oil smoke on the die head; however, in this process, oil gas will also accumulate on the fume hood device, especially adhere to and accumulate on the inner wall of the fume hood, and it lacks corresponding cleaning components to clean it, which not only has a negative impact on the subsequent exhaust of oil smoke, but the oil smoke adhered to it will also cool and drip, posing a threat to the product processing quality; further improvement and optimization are needed.
