Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a variable-distance material transfer mechanism for unloading battery cells. Background Art

[0002] In lithium battery production, in order to improve efficiency and reduce costs, multiple parts / semi-finished products are generally processed at the same time at one workstation. In some fully automatic production equipment, due to reasons such as spatial layout, the workstations are often arranged in a non-linear manner, resulting in the problem of different spacing between multiple parts / semi-finished products during the workstation conversion process. For example, during the process of unloading battery cells, the material transfer mechanism is required to first clamp the battery cells with different spacing and then move them to the storage turnover box. If the spacing is not adjusted, it is easy to damage the battery cells during placement, or some storage cells in the weekly box will have holes. At present, most of the solutions are to add an equidistant adjustment mechanism to the material transfer mechanism or to manually check the weekly box and replenish the material. The material transfer mechanism is complicated, the operating space is increased, and the labor cost is high. Utility Model Content
