Pressing device for welding of battery production line

Abstract

The invention belongs to a pressing device used for welding, in particular to a pressing device for welding of a battery production line. The pressing device mainly solves the technical problems that a pressing device commonly used in current production is complex in adjusting step, error compensation cannot be performed, and the fixing stability degree is low. According to the technical scheme, the pressing device for welding of the battery production line is composed of three parts of an upper floating pressing board assembly, a lower carrying board assembly and an installation bottom board, and the upper floating pressing board assembly and the lower carrying board assembly are fixed to the installation bottom board. A bottom board of the upper floating pressing board assembly is fixed to the installation bottom board. A supporting board is in a bent-arm shape. The lower end of the supporting board is fixed to the bottom board. An air cylinder installation board is fixed to the upper end of the supporting board. A downward-pressing air cylinder is fixed to the air cylinder installation board. A connecting board is fixed to an output shaft of the downward-pressing air cylinder. The connecting board is connected with a fixing seat through elastic pins. A rotary shaft is sleeved with the fixing seat. A floating swing seat is installed on the fixing seat. An upper pressing board seat with an upper floating pressing board is installed on the floating swing seat. The lower carrying board assembly comprises a support, a cushion board and a lower carrying board. The support is fixed to the installation bottom board and provided with the cushion board. The lower carrying board is fixed to the cushion board. The pressing device is used for pressing polar bands and polar lugs on the battery production line in a floating manner in the welding process.

Description

technical field [0001] The invention belongs to a pressing device for welding, which is used for floating and pressing of a welding pole band and a pole lug on a battery production line. Background technique [0002] In the production process of the battery pole piece, the pole strip and the pole lug must be fixed and pressed before welding, and then welding can be carried out, otherwise defects such as virtual welding and de-soldering will be caused. The quality of the welding has a decisive influence. At present, in the production process of the battery plate, the pressing devices for welding the pole strips and the tabs generally have the following problems: the rigid pressing devices are used in the production, and the adjustment steps are complicated, and the pressure on the pole strips and the tabs is very complicated. The tightening effect depends entirely on the manufacturing accuracy and assembly accuracy of the device. In practice, mechanical parts have manufactu...
