Description

Technical Field

[0001] This utility model relates to the technical field of battery welding processing, specifically to a laser welding prototype machine. Background Technology

[0002] The development, application, and widespread use of modern power electronics technology have led to the extensive use of rechargeable batteries, especially lithium batteries, in various electrical, electronic, and power-related products. These products almost exclusively use battery packs composed of individual cells, and the role of conductive connectors in connecting and assembling these battery packs is crucial. During processing, nickel sheets (conductive connectors) are spot-welded to the positive and negative terminals of the battery. This spot welding is typically done manually using a hand-held mold. The nickel sheet and battery are positioned within a specially designed mold, and then spot-welded manually. To address the aforementioned issues, automated welding equipment is employed to automate material feeding, positioning, welding, and unloading, thereby improving welding efficiency. However, existing automated welding equipment uses a lifting positioning method for material positioning, which involves setting up a lifting platform to lift the material, then lowering it after welding to continue conveying. This lifting and lowering process is cumbersome and affects efficiency. Existing automated welding equipment uses direct spot welding, which suffers from inaccurate welding areas and poor weld quality. Furthermore, the lack of a pressure-holding function leads to warping of the nickel sheets (conductive connecting pieces) due to temperature deformation during welding, affecting weld quality and stability. Existing automated welding equipment uses a jig tray for positioning and conveying battery packs. After welding, the product is unloaded from the jig tray, requiring manual repositioning of the jig tray to the starting position before placing new materials. This method increases labor intensity, slows down recovery efficiency, and impacts overall production efficiency. Utility Model Content
