Abstract

The invention discloses an electrode lug welding device and a work method. The electrode lug welding device comprises a single-axis mechanical hand, a linear guide rail A, a linear guide rail B, a sliding plate and an ultrasonic welding machine. The single-axis mechanical hand is installed on the side, away from a welding position, of a bottom plate, and a screw nut is arranged on the single-axis mechanical hand. The linear guide rail A is installed on the side, close to the welding position, of the single-axis mechanical hand, and a sliding block A is connected to the linear guide rail A in a sliding manner. The linear guide rail B is installed on the side, close to the welding position, of the linear guide rail A, and a sliding block B is connected to the linear guide rail B in a sliding manner. The sliding plate is located above the linear guide rail A and the linear guide rail B and is fixedly connected with the screw nut, the sliding block A and the sliding block B. The ultrasonic welding machine comprises an installation plate, a rack, an air cylinder A and a welding machine upper module. By means of the electrode lug welding device and the work method, an electrode lug can be limited in a left-right manner, limited in a vertical manner and limited in a forward manner, pleating of the electrode lug is prevented, and the welding quality of the electrode lug is ensured.

Description

technical field [0001] The invention relates to the technical field of tab welding, in particular to a tab welding device and a working method. Background technique [0002] The tab is a raw material for lithium-ion polymer battery products. It is a metal conductor that leads the positive and negative electrodes out of the battery. In layman's terms, the tab is the ear of the positive and negative poles of the battery, which is used for charging and discharging. At present, in the production process of cylindrical batteries, the tabs need to be welded, and the tabs are mostly welded by ultrasonic welding. The welding quality has an important impact on the quality of the cell product, and the welding operation speed directly affects the equipment efficiency. The requirements of the equipment for tab welding are: firm welding, accurate tab position, and fast operation. In the prior art, the positioning accuracy of the tabs of the lithium battery cell winding equipment is not ...
