Problems solved by technology

However, because the battery connector is made of hard material, the overall hardness is high, and after repeated bending, cracks will appear at the bending point, or even be broken, which will shorten the service life and even cause safety hazards
[0003] At the same time, as the current and power requirements for new energy batteries are increasing, the thickness of the battery connection sheet is increased from 0.3-0.4mm to 0.8-1.0mm, or even thicker. After the thickness is increased, the battery with greater hardness There will be problems such as difficult bending and inaccurate bending position of the connecting piece

Abstract

The invention discloses a production process of a lap welding flexible connecting piece of a new energy battery. The production process comprises the following steps of (1) manufacturing multiple layers of soft switching pieces, and molding a hard collector plate; (2) lapping the hard collector plate with the multiple layers of flexible switching pieces; (3) punching and forming the multiple layers of soft switching pieces, punching off redundant material sheets, and punching out welding holes; (4) welding upper poles on the welding holes; and (5) stamping and leveling the multiple layers of flexible switching pieces to obtain the flexible connecting sheet. The invention also discloses a product obtained by implementing the above method. The obtained flexible connecting sheet meets the economical, rapid and accurate forming requirements of the hard collector plate and also meets the production requirements of easy bending and bending resistance of the product, the connecting segment is a multi-layer flexible metal sheet, is high in flexibility and bending randomness and is suitable for bending deformation, the position is accurate after multiple times of bending, cracks and breakage are avoided, the service life of the flexible connecting sheet can be prolonged, the production convenience of a top cover is improved, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to a production process of a battery connection sheet, in particular to a production process of a new energy battery lap welding soft connection sheet and a product thereof. Background technique [0002] The battery connection sheet is a component that connects the battery top cover assembly to the battery body. At present, most of the battery connectors on the market are formed by direct integral stamping of hard materials (for example, hard aluminum). When the battery connecting piece is used, the battery connecting piece needs to be bent. However, because the battery connecting piece is made of hard material, the overall hardness is high, and after repeated bending, cracks will appear at the bending point, or even be broken, shortening the service life, and even causing safety hazards. [0003] At the same time, as the current and power requirements for new energy batteries are increasing, the thickness of the battery connect...
