According to the classification of lithium battery packaging materials, lithium batteries can be mainly divided into two categories: metal shell lithium batteries and soft pack batteries.

[0003] For metal shell lithium batteries, it is necessary to place an insulating sheet between the battery cell and the metal shell of the metal shell lithium battery. The insulating sheet is a thin sheet installed in the metal shell lithium battery to keep the circuit in an open state. When assembling and processing the insulating sheet, it is usually necessary to place the insulating sheet on the battery cell, and then place the battery cell and the insulating sheet into the metal shell. During production, the insulating sheet is placed in the groove at the upper end of the insulating sheet jig, and the battery cell is placed in the groove at the upper end of the battery cell jig. Traditionally, the insulating sheet at the upper end of the insulating sheet jig is manually taken out, and the insulating sheet is placed on the upper end of the battery cell in the battery cell jig, thereby completing the loading of the insulating sheet. In order to cooperate with the uninterrupted operation of the production assembly line, the operator must also wait on the production assembly line for a long time, resulting in low work efficiency and high labor intensity.
