Abstract

A device for welding the tabs at the bottom of the battery cell and the steel shell according to the present invention is provided with a circular assembly line for charging the battery core, a feeding mechanism for the battery core, a turntable for welding the tab steel shell, a material transfer mechanism for the battery core, and an insulating ring. The assembly turntable, cell blanking mechanism, cell recovery mechanism, surrounding the tab steel shell welding turntable are equipped with a central hole size primary CCD detection mechanism, a central hole reaming mechanism, a central hole size secondary CCD detection mechanism, and tabs. The steel shell welding mechanism is surrounded by the insulating ring assembly turntable, which is sequentially equipped with a battery cell lug mechanism, a cell lug correction mechanism, an insulating ring assembly mechanism, and a cell appearance CCD detection mechanism, thereby improving the battery bottom lug as a whole. Mechanical automation level for welding with steel shells.

Description

technical field [0001] The invention relates to the technical field of mechanical automation production of electric cores, in particular to a device for realizing the welding of tabs at the bottom of electric cores and steel shells. Background technique [0002] With the continuous development of society and the continuous advancement of science and technology, mechanical automation production has become a development trend, and gradually replaces traditional manual labor, injecting new power sources for the sustainable development of enterprises. Therefore, battery cell manufacturing enterprises also need to keep pace with the times, actively promote technological transformation through transformation and upgrading, and vigorously develop mechanical automation production, so as to improve the "smart manufacturing" level of enterprises and achieve sustainable development of enterprises. [0003] Such as figure 1 As shown, it is a structural diagram of a cylindrical battery ...
