Embodiment 1

[0072] Example 1, taking two transfer trays as an example, a welding method for an asymmetric tab battery module, marking the A side of the module and the B side of the module,

[0073] S1. The module enters the welding station:

[0074] S11. The stacked modules are respectively placed on the No. 1 transfer tray 33 and the No. 2 transfer tray 24, and the No. 1 transfer tray 33 and the No. 2 transfer tray 24 are placed between the No. 1 double-speed chain 31 and the No. 2 double-speed chain 32 , and placed at intervals with the pneumatic stopper as the boundary, the No. 1 transfer tray 33 and the No. 2 transfer tray 24 enter the welding station along with the double-speed chain;

[0075] S2. Module positioning

[0076] S21, the No. 1 pneumatic stop card 35 and the No. 2 pneumatic stop card 36 are in the rising state in a natural state so as to stop the module at the current station, and the position sensor 37 will transmit the detected signal to the controller in real time. Wh...

Abstract

The invention provides a welding device and method for an asymmetric tab battery module. The welding device comprises a module transfer mechanism, a lead screw movement mechanism and a jacking and holding mechanism are arranged on the two sides of the module transfer mechanism correspondingly, a copper nozzle pressing mechanism is installed above the lead screw movement mechanism, and a jacking mechanism is installed below the module transfer mechanism. Transfer trays used for containing battery modules are arranged above the lead screw movement mechanism, after the transfer trays rotate by 90 degrees, the axes of the transfer trays coincide with the axis of the jacking and holding mechanism, and the lead screw movement mechanism, the copper nozzle pressing mechanism, the module transfer mechanism, the jacking mechanism and the jacking and holding mechanism are in signal connection with a controller separately. According to the welding device and method for the asymmetric tab battery module, the tab copper nozzle pressing mechanism automatically moves to be separately and correspondingly positioned, pressed and welded with the surfaces A and B of the module, so that the automatic welding of battery module tabs is realized.

Description

technical field [0001] The invention belongs to the field of soft pack power batteries, and in particular relates to a welding device and a welding method for an asymmetric tab battery module. Background technique [0002] At present, most of the module welding of domestic battery manufacturers adopts automatic laser welding, and the structure diversification of the module needs to match the corresponding automation scheme design. In the existing technology, there are differences in the welding positions of the tabs on both ends of the asymmetric tab welding structure battery module. , the same compression tool cannot be used for compression; it is necessary to make different compression tools for this structure for separate compression welding; the existing welding scheme needs to be separately compressed offline, which cannot be automated production; resulting in the position of the tab during welding Inaccurate, low degree of automation, easy to cause problems such as low...
