Electrode clamp layout structure of battery lug in battery charging and discharging equipment and method

Abstract

The invention relates to an electrode clamp layout structure of a battery lug in battery charging and discharging equipment and a method. The structure comprises two groups of electrode clamps, wherein two clamps in each group of electrode clamps are vertically laid out and arranged and can move in vertical direction and horizontal direction respectively. When the method is applied to batteries of different electrode outlet modes, the first clamp moves in the vertical direction to be adjusted to a position which is suitable for clamping a battery lug, and a second clamp can move in the horizontal direction to be adjusted to a position which is suitable for clamping another battery lug according to positions of the battery lugs. The electrode clamp disclosed by the invention is simultaneously suitable for a lithium battery of a single-side electrode outlet mode and a lithium battery of a double-side electrode outlet mode without replacing or increasing or decreasing the clamp. The electrode clamp layout structure is particularly suitable for a formation automatic production lien of the lithium battery of the single-side electrode outlet mode and the lithium battery of the double-side electrode outlet mode; and double-row arrangement of the batteries in a pellet can be realized.

Description

technical field [0001] The invention relates to the technical field of lithium battery formation, in particular to a layout structure and method for electrode clips to clamp battery tabs during battery charge and discharge in lithium battery formation automation equipment. Background technique [0002] The demand for batteries for new energy vehicles has risen suddenly. The battery formation process is an important link in the production of battery products and the main factor affecting the quality of batteries. The automation of battery formation is a major technical means to solve the problem of battery production and quality, and the technologies and methods suitable for formation automation are a research hotspot. [0003] The two tabs of a pack of lithium batteries are basically arranged in parallel. At present, regardless of manual formation equipment or automated formation equipment, the two clips of a set of electrode clips used to clamp the lithium battery tabs are ...

AI Technical Summary

Problems solved by technology

Such tab clamping method and clip layout make it impossible for the same set of battery clips to be suitable for batteries with two kinds of electrode outlets at the same time; and for batteries with double-sided electrode outlets, they can only be placed in a single row on the charging and discharging station of the automated production line. Reduced production efficiency, but also reduced the versatility and compatibility of automated production lines
