They are widely used in various fields. However, in the production process of polymer lithium-ion batteries, they need to go through steps such as loading, heating and pressurizing, and formation. In the original battery production technology, the spacing between adjacent batteries in the battery loading mechanism and the spacing between adjacent batteries during formation are fixed. The robot needs to grab the battery multiple times and travel back and forth for a longer distance to the loading mechanism, resulting in operation waste and affecting work efficiency. At the same time, the traditional loading mechanism cannot adapt to a variety of batteries of different sizes, which limits the limitations of equipment production. Therefore, there is an urgent need for a loading mechanism that can adjust the spacing between the loaded batteries at any time and can quickly adapt to batteries of different specifications.
