Description

TECHNICAL FIELD

[0002] Lithium batteries are a new generation of power and energy storage power sources, with superior performance, reliable process, and wide application. Therefore, in order to adapt to different uses and equipment, various models of lithium batteries are needed. However, the probes in the current lithium battery detection equipment are usually fixed directly on the probe plate, making it inconvenient to disassemble and assemble the probes, and unable to adapt to the production of lithium batteries of various models. When producing lithium batteries of different models, the entire probe mechanism needs to be replaced manually, which not only increases production costs, but also wastes manpower. In order to maximize the use of equipment and quickly ensure the safe operation of equipment, the spacing between the probes needs to be adjusted to meet the production needs of lithium batteries of different models. This requires the probes to be easy to install, easy to maintain, firmly installed, modularized in structure, easy to transport, and to consider issues such as firm fixation and contact resistance. The installation of the charging and discharging equipment is very high after being stacked, the space of the storage location is limited, and it is difficult for personnel to work inside the internal mechanism of the machine.
