Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery processing, and in particular to a dust collection device for the opening of a battery cell steel casing. Background Technology
[0002] Dust collection is an essential component in the battery steel casing grooving manufacturing process. During grooving, the roller cutter's pressure against the battery casing easily generates fine metal shavings. If residual dust and debris inside the casing opening are not effectively removed, they can easily fall into the battery cell, contaminating the electrolyte and affecting battery quality and safety. Currently, most production lines use internal dust collection methods, where the suction head extends into the casing and comes into contact with the cell surface to collect dust. This method effectively removes dust and debris from inside the cell, preventing debris from accumulating inside. However, it is less effective at cleaning the casing opening, failing to effectively remove dust and debris from there. During subsequent processing, these debris can easily fall into the cell, contaminating the electrolyte, affecting battery quality and safety, and potentially causing explosions due to short circuits. This poses a significant safety hazard and can result in serious losses for customers. Therefore, a dust collection device for the opening of the battery cell steel casing is proposed.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the battery cell to be vacuumed is vertically placed inside the limiting block, the cam rotating shaft rotates and drives several cam lifting frames to move up and down on the side of the support platform. During the up and down movement of the cam lifting frame corresponding to the position of the limiting block, the top rod is driven through the support platform and lifted into the vacuum head. During the up and down movement of the cam lifting frame, the vacuum head is also driven to move up and down, so that the steel shell of the battery cell is inserted into the vacuum head. Then, the vacuum head adsorbs the iron filings at the steel shell of the battery cell. During the lifting process, the battery cell is limited by the path by the limiting block, ensuring that the battery cell will not deviate during the lifting process.
[0012] The cam turret structure enables rapid and effective secondary dust removal from the batteries after grooving, preventing dust generated during grooving from entering the steel casing and contaminating the electrolyte, thus affecting battery performance and safety. It also prevents metal debris adhering to the outside of the casing from contaminating the equipment and affecting its service life. This ensures battery production quality and efficiency, saves production costs and time, and is beneficial for mass production.
