Problems solved by technology

[0002] Welding the protective plate on the lithium battery requires a high process. Generally, a semi-automatic device is used for processing. The work efficiency is low, and sometimes the battery cell or the protective plate is easily damaged. It is necessary to provide a lithium battery automatic spot welding machine with higher precision and higher automation.
Moreover, due to the different types of lithium batteries, the types and shapes of the protective plates required are different, so different products need to have specific processes, and the processing methods and steps required by various specific processes are different. The welding machine has high individual requirements and difficult design

Abstract

Disclosed is a battery welding electrode assembly. The battery welding electrode assembly comprises a motor, a motor support, an eccentric wheel mechanism, a gear assembly and a swing arm; the motor support comprises two end plates and a hanging beam which is arranged between the end plates; the motor is arranged on the two end plates; the swing arm, the eccentric wheel mechanism and the gear assembly are arranged in the center of the hanging beam which is arranged in the middle; the center of the hanging beam is provided with a pair of symmetric inner supporting plates; the gear assembly and the eccentric wheel mechanism are arranged on the inner supporting plates; the linkage is performed between the a rotating shaft of the motor and the gear assembly; the eccentric wheel mechanism is driven by the gear assembly; the swing arm is driven by the eccentric wheel mechanism to swing. According to the battery welding electrode assembly, the gear assembly is driven by an electrode, the eccentric wheel mechanism is driven by the gear assembly to enable the swing arm to rotate within the accurately calculated angle, and accordingly an electric welding head which is arranged on the swing arm can move rapidly to implement the spot welding.

Description

【Technical field】 [0001] The invention relates to the field of welding of lithium battery cells, in particular to an automatic electric welding machine. 【Background technique】 [0002] Welding the protective plate on the lithium battery requires a high process. Generally, a semi-automatic device is used for processing. The work efficiency is low, and sometimes the battery cell or the protective plate is easily damaged. It is necessary to provide a lithium battery automatic spot welding machine with higher precision and higher automation. . Moreover, due to the different types of lithium batteries, the types and shapes of the protective plates required are different, so different products need to have specific processes, and the processing methods and steps required by various specific processes are different. Welding machines have high individual requirements and are difficult to design. [0003] Welding the protective plate on the lithium battery, except for some feeding ...
