Full-automatic welding workbench for pole lugs and caps of cylindrical batteries

Abstract

The invention relates to a full-automatic welding workbench for pole lugs and caps of cylindrical batteries. The full-automatic welding workbench is characterized by comprising a machine base and a rotary workbench body arranged on the machine base; the rotary workbench body is driven to rotate by a servo motor arranged in the machine base; a plurality of jigs for storing cell shells are uniformly arranged on the inner side of the circumference of the rotary workbench body in the radial direction; the outer side of the circumference of the rotary workbench body is sequentially provided with a cell shell feeding unit, a pole lug leveling unit, a pole lug cleaning unit, a pole lug wiping unit, a cap feeding unit, a galvanometer laser welding unit, a tensile test unit and a discharging unit in the rotating direction; and a plurality of procedures such as feeding, leveling, cleaning, wiping, welding, testing and discharging are completed through cooperation of all the units. According to the full-automatic welding workbench, the automation degree is high, meanwhile, the labor cost is reduced, and the welding quality and the production efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of battery processing equipment, and in particular relates to a workbench capable of fully automatic welding cylindrical battery tab caps. Background technique [0002] The cylindrical battery is mainly composed of a shell, a cap, a positive electrode and a negative electrode. The positive electrode is welded to the cap through the positive tab, the negative electrode is welded to the bottom of the shell through the negative tab, and the cap is tightly placed on the opening of the shell. The welding quality of the cap and tab is affected by the cleanliness of the tab surface. Before welding, the tab needs to be cleaned, and this process is generally cleaned manually by workers. Not only is the labor cost high, but the cleaning effect is difficult to guarantee. In addition, after welding High-quality batteries often need to be subjected to a tensile test to detect whether the welding quality is good or bad. ...
