The invention relates to the technical field of lithium batteries, and discloses automatic edge pressing equipment for a lithium battery explosion-proof sheet. The automatic edge pressing equipment comprises a rack, and an index plate device, an explosion-proof sheet conveying device, an explosion-proof sheet edge pressing device and a discharging device which are arranged on the rack, wherein theexplosion-proof sheet conveying device is used for conveying an explosion-proof sheet to a station assembly of the index plate; the explosion-proof sheet edge pressing device is used for carrying outedge pressing on the explosion-proof sheet; and the discharging device is used for transferring and discharging the explosion-proof sheet subjected to edge pressing. The automatic edge pressing equipment has the advantages that a plurality of explosion-proof sheets can be conveniently conveyed and subjected to edge pressing at the same time, and the edge pressing stability and the edge pressing quality are improved.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an automatic crimping device and a crimping method for an explosion-proof sheet of a lithium battery. Background technique [0002] The explosion-proof sheet is one of the key components of lithium-ion batteries. Its structure is as a battery cap explosion-proof sheet disclosed in the Chinese utility model patent with the publication number CN208284541U, which is coaxially connected with the battery steel cap, and the battery block explosion-proof sheet It includes a burst-proof disc outer ring, a burst-proof disc inner ring, a burst-proof disc connection part and an explosion-proof score, the burst-proof disc inner ring is connected with the burst-proof disc outer ring through the burst-proof disc connection part, and the explosion-proof disc The thickness of the connection part of the disc is greater than the thickness of the outer ring of the rupture disc. The explo...
