Abstract

The present invention provides a battery pack connector pressure welding method, comprising: placing the soft connection auxiliary body on the surface of the soft connection main body; and using spot welding to make the soft connection The auxiliary body is fixed with the soft connection main body. The present invention provides a method for pressure welding of battery pack connectors, using the above positioning method to fix the soft connection auxiliary body and the soft connection main body. In the embodiment of the present invention, spot welding is used to fix the soft connection auxiliary body and the soft connection main body, so as to provide positioning for subsequent pressure welding. The soft connection auxiliary body and the soft connection main body are fixed by spot welding, which can avoid positioning fixture pinch marks and avoid positioning deviation caused by glue. The embodiment of the present invention provides a battery pack connection pressure welding method, which solves the waste of materials caused by using glue and positioning fixtures for positioning in the prior art through positioning, pressure welding fusion, punching and pressing holes, edge stamping and blanking, etc., positioning Inaccurate and unsightly issues.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a pressure-welding positioning method and a pressure-welding method for a battery pack connector. Background technique [0002] The battery pack connector is an important part of the battery pack, and the soft connection can serve the purpose of shock resistance. The industry usually uses copper foil or aluminum foil as the main material for soft connections. Copper foil or aluminum foil is easily oxidized, which increases the resistance of the connector. In order to reduce the resistance, the nickel foil is attached to the outer surface of the copper or aluminum foil by pressure welding. During the bonding process, the surface to be bonded of the nickel foil needs to face the surface to be bonded of the copper foil or the aluminum foil without offset, so that the nickel foil and the copper foil or the aluminum foil need to be positioned. At present, the industry usually uses...
