Abstract

The invention relates to welding equipment, in particular to battery tab resistance welding equipment. The battery tab resistance welding equipment provided by the invention can be used for stably positioning and realizing automatic welding. Battery tab resistance welding equipment comprises a resistance welding fixing frame, a base, a resistance spot welding machine, a transmission mechanism, a tab pushing frame, a battery pushing frame and the like. The resistance spot welding machine is fixedly connected to the resistance welding fixing frame, the transmission mechanism is arranged on the transmission fixing frame and the resistance welding fixing frame, the tab pushing frame is slidably connected to the left side of the workbench and slidably connected to the left side of the sliding groove fixing plate and slidably connected to the right side of the workbench and slidably connected to the right side of the sliding groove fixing plate, and the transmission mechanism is arranged between the battery pushing frame and the tab pushing frame. Before welding, the first rubber plate and the second rubber plate respectively press the battery and the tab, so that the battery tab is prevented from displacement during welding, and the welding accuracy is ensured.

Description

technical field [0001] The invention relates to a welding device, in particular to a battery tab resistance welding device. Background technique [0002] The tab is a raw material for lithium-ion polymer battery products. The battery is divided into positive and negative poles. The tab is the metal conductor that leads the positive and negative poles out of the battery cell. In layman's terms, the ears of the positive and negative poles of the battery It is the contact point when charging and discharging. This contact point is not the copper piece we see on the outside of the battery, but a connection inside the battery. In the process of battery production, it is necessary to complete the connection of the tabs by spot welding. The traditional method is mostly manual, but this method has a low degree of automation and low production efficiency. It is impossible to do the battery tabs during manual welding. Accurate and stable welding, and there will be deviation or even dr...
