Battery case laser welding clamp

Abstract

The invention aims to provide a battery case laser welding clamp. A centering gap adjusting mechanism can guarantee a stable structure, and the consistency of the center of a fixed battery and the center of an indexer disk is good when the type of the battery is replaced, so the product quality is improved. In order to achieve the effect, the battery case laser welding clamp comprises a pedestal and the centering gap adjusting mechanism which is arranged on the pedestal, wherein the centering gap adjusting mechanism comprises a back plate which is arranged on the pedestal; an indexer is arranged between the pedestal and the back plate; an adjusting screw is arranged on the horizontal middle axis of the back plate and penetrates through the nut to be connected with left and right battery clamping plates. Since the technical scheme is adopted, when the type of the battery of the battery case laser welding clamp is replaced, only a spinner is required to be rotated to drive the adjusting screw; the left battery clamping plate and the right battery clamping plate move symmetrically along the longitudinal middle axis of the back plate to guarantee that the consistency of the center of the battery between the left battery clamping plate and the right battery clamping plate and the center of the indexing disk and avoid reduction in machining precision due to replacement of the battery.

Description

technical field [0001] The invention relates to a fixture, in particular to a battery case laser welding fixture. Background technique [0002] Laser welding has always been a key process in the manufacturing process of lithium batteries. From stainless steel shells to aluminum shells to polymers, laser welding is widely used. With the continuous development of the industry, higher requirements have been put forward for the efficiency and quality of laser welding, and optical fiber transmission laser welding has been used. Since the main unit of the welding machine and the focusing head are connected flexibly, this method is easier to match with the assembly line , to achieve full automation. The appearance and performance of welds have also been significantly improved. However, there are further requirements for the battery case laser welding jig, and the precision requirements are higher. In the prior art, fixed positioning grooves are usually used on the battery shell ...

AI Technical Summary

Problems solved by technology

However, the battery case laser welding jig in the prior art usually adopts a fixed positioning groove, and the positioning groove needs to be replaced when the battery is transformed, the structure is complicated, the operation is inconvenient, and the consistency between the center of the battery and the center of the index plate is poor

This not only reduces the production accuracy, affects the product quality, but also increases the production cost, which has a great adverse effect on the reputation of the enterprise.
