Description

Technical Field

[0001] This utility model relates to the field of equipment technology, and in particular to an automated spot welding and assembly equipment. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes, forming a cup, tank, or other container or composite container that generates an electric current. It has a positive and a negative electrode. With technological advancements, the term "battery" now generally refers to any small device that generates electrical energy, such as a solar cell. The main performance parameters of a battery include electromotive force, capacity, specific energy, and resistance. Using batteries as an energy source provides a stable voltage, stable current, long-term stable power supply, and minimal susceptibility to external influences. Batteries are simple in structure, portable, easy to charge and discharge, unaffected by external climate and temperature, and offer stable and reliable performance, playing a significant role in various aspects of modern life.

[0003] To accelerate battery production, manufacturers typically use equipment to perform welding and assembly processes. However, current battery production equipment can only complete a single manufacturing step, such as assembly or electrode welding. This means that two workstations and two machines are needed to assemble the battery and weld the electrode plates, preventing integrated production. Furthermore, manual loading and unloading are required, reducing production efficiency. Therefore, it is necessary to propose a new solution to address these issues. Utility Model Content
