Cylindrical lithium battery and collector welding machine achieving reliable battery cell feeding

Abstract

The invention relates to a cylindrical lithium battery and collector welding machine achieving reliable battery cell feeding. A collector welding production line comprises a conveying line, a material positioning device arranged on the conveying line, a battery cell feeding device, a collector feeding device, a welding device, a collector bending device and a finished product discharging device, wherein the battery cell feeding device, the collector feeding device, the welding device, the collector bending device and the finished product discharging device are arranged along the conveying line in sequence, and transfer working positions of the battery cell feeding device, the collector feeding device, the welding device, the collector bending device and the finished product discharging device are matched with the material positioning device. The battery cell feeding device comprises a battery cell conveying track and a battery cell transfer mechanism. The battery cell transfer mechanism comprises a battery cell feeding lifting air cylinder, a battery cell transfer rotating driving motor and a battery cell clamping manipulator. The battery cell clamping manipulator is provided with a battery cell chuck capable of being opened and closed and a battery cell chuck installation arm installed on a motor shaft of the battery cell transfer rotating driving motor. The battery cell transfer rotating driving motor is installed on a telescopic arm of the battery cell feeding lifting air cylinder. The cylindrical lithium battery and collector welding machine achieving reliable battery cell feeding is used for automatically welding collectors to battery cells and automatically bending the collectors, and has the advantages of being good in product processing quality, compact in structure and high in working efficiency.

Description

technical field [0001] The invention relates to welding equipment, specifically welding assembly equipment for welding current collectors to cylindrical lithium batteries. Background technique [0002] battery current collector before assembly, such as figure 2 As shown, the current collector is a flat metal sheet, which includes a circular surface and a rectangular strip arranged on one side of the circular surface, the rectangular strip is bent, and the circular surface is welded to the battery core in the hydrogen battery shell Positive end surfaces such as figure 1 As shown, the current collector tab transfers the positive current to the positive cap. [0003] The welding of the existing battery current collectors adopts manual welding, or only uses battery tooling for positioning, and then welds with ordinary welding equipment, which has the defects of inconvenient operation and poor product quality.
