Compression welding device of polar group of battery

Abstract

The invention discloses a compression welding device of a polar group of a battery, and the compression welding device comprises a first baseplate (1), a compression device (2), a plurality of fixed plates (3), a plurality of movable plates (4) and moving plate connecting plates (5) for fixing the movable plates (4), wherein the compression device (2) and the fixed plates (3) are fixed on the baseplate (1), the movable plate connecting plates (5) are connected with the compression device (2), and the compression device (2) is used for driving the movable plate connecting plates (5) and the movable plates (4) to move together. By arranging the compression device (2), the plurality of the fixed plates (3) and the plurality of the movable plates (4) on the first baseplate (1), the compression device can be used for driving the movable plates to move so as to perform compression welding on the polar group, thereby being applicable to welding the polar groups in different sizes, greatly improving the production efficiency and reducing the rejection rate of products.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery electrode group compression welding device. Background technique [0002] In the production of valve-regulated sealed lead-acid batteries, especially in the welding production of medium and large dense lead-acid batteries, many factories still use the traditional manual compression of the electrode group into the comb plate, so that the manual compression of the electrode group into the comb Shaped boards are a waste of time and manpower in operation, and the production efficiency is low. Generally, one welding station requires two workers to operate, and this method is likely to cause AGM (Absorptive Glass Mat, ultrafine glass fiber) partitions Cracks or dislocation deformation of the pole group will affect the quality of the battery. Although a kind of COS (Cast On Strap, casting connecting strip) electrode group casting welding is emerging in the lead-acid battery...

[0002] In the production of valve-regulated sealed lead-acid batteries, especially in the welding production of medium and large dense lead-acid batteries, many factories still use the traditional manual compression of the electrode group into the comb plate, so that the manual compression of the electrode group into the comb Shaped boards are a waste of time and manpower in operation, and the production efficiency is low. Generally, one welding station requires two workers to operate, and this method is likely to cause AGM (Absorptive Glass Mat, ultrafine glass fiber) partitions Crack or pole group dislocation deformation, thus affecting battery quality

Although a kind of COS (Cast On Strap, casting connecting strip) electrode group casting welding is emerging in the lead-acid battery industry, the one-time investment of this kind of machinery and equipment is too high, and the maintenance work of the machine is large, and the quality and education level of the operators are required. Harsh, more difficult to popularize
