Abstract

The invention provides a battery pack connecting piece pressure welding positioning method. The battery pack connecting piece pressure welding positioning method comprises the steps of placing a flexible connection accessory body on the surface of a flexible connection main body; and fixing the flexible connection accessory body to the flexible connection main body through spot welding in a presetarea of the flexible connection accessory body. The invention further provides a battery pack connecting piece pressure welding method. The flexible connection accessory body and the flexible connection main body are fixed through the battery pack connecting piece pressure welding positioning method. According to the battery pack connecting piece pressure welding positioning method and pressure welding method, the flexible connection accessory body and the flexible connection main body are fixed through spot welding to realize the positioning effect for subsequent pressure welding. The flexible connection accessory body and the flexible connection main body are fixed through spot welding. In this way, clamp marks of a positioning fixture and positioning deviation caused by glue can be avoided. According to the battery pack connecting piece pressure welding method provided by the embodiment of the invention, the problems that material waste and inaccurate and unaesthetic positioning caused by positioning through glue and a positioning fixture in the prior art are solved through positioning, pressure welding fusion, hole punching, edge punching and blanking and the like.

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...
