Abstract

The invention provides a spot welding connecting device for lithium battery module production. The pot welding connecting device comprises a spot welding fixing frame, a movable installing frame, electrode contact blocks and a central sleeve, wherein vertical guide columns are symmetrically arranged on the left side and the right side of the spot welding fixing frame, the movable installing frame is arranged in the middle of the spot welding fixing frame, the electrode contact blocks are symmetrically arranged on the front side of the movable installing frame, and the central sleeve is arranged between the electrode contact blocks. According to the spot welding connecting device, a plurality of welding pressing rods of different sizes can be stored at the same time through a adjusting rotating wheel, the needed welding pressing rods can be rotated to the position above the electrode contact blocks by rotating the adjusting rotating wheel, the welding pressing rods on the two sides can be pressed at the same time to synchronously move downwards through an installing pressing rod so that the welding pressing rods can be connected, installed and fixed, the installing pressing rod can be pulled out of the electrode contact blocks by moving upwards to be disassembled so that different welding pressing rods can be quickly installed and replaced by rotating the adjusting rotating wheel and moving the installing pressing rod, and different spot welding machining requirements are met.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of lithium battery production, and in particular to a spot welding connection device for lithium battery module production. Background technique [0002] At present, nickel strips are usually used for connection between lithium batteries, and DC spot welding devices are usually used for spot welding connections between nickel strips and lithium batteries, and the corresponding spot welding devices generally fix corresponding size welding on the two electrodes. The pressure rod is used to conduct a large current by welding the pressure rod to contact the nickel strip, so that the nickel strip and the lithium battery electrode are melted and fixed together. For different sizes of nickel strips and lithium batteries, it is usually necessary to use pressure with different sizes of welding joints. The larger the nickel strip and the lithium battery, the larger the welding head of th...
