Background
Lithium battery refers to a battery containing Lithium including metallic Lithium, lithium alloy and Lithium ion, lithium polymer in electrochemical system. Lithium batteries can be broadly classified into two types: lithium metal batteries and lithium ion batteries. A lithium battery is a type of rechargeable battery that mainly operates by movement of lithium ions between a positive electrode and a negative electrode. Batteries using a material containing lithium as an electrode are typical of modern high-performance batteries. With the development of new energy greatly promoted by the state, the demand of various industries on lithium ion power batteries is increasing day by day, and a battery cell in a composition structure of the lithium ion power battery is a core component of the lithium ion power battery, and the battery cell is generally formed by mutually overlapping positive and negative pole pieces in a staggered manner. The battery core composition structure comprises a plurality of positive and negative pole pieces which are staggered and overlapped up and down, and the positive and negative pole pieces are isolated and insulated by a diaphragm. At present, lithium battery equipment with more advanced domestic technology is mainly mastered by foreign equipment suppliers, and domestic high-end lithium battery lamination equipment mainly depends on import at present.
The electric core of the lithium ion battery is generally formed by overlapping positive and negative pole pieces in a staggered manner, and an insulating diaphragm is required to be inserted between the positive and negative pole pieces.

Aiming at the belt-shaped lamination process, the following technical difficult problems need to be solved in the process of carrying out automatic lamination design: after the strip diaphragm is guided out by the diaphragm releasing mechanism, the strip diaphragm is clamped by the diaphragm pulling mechanism, is pulled out from left to right above the lamination platform by taking the middle part of the lamination platform as a fulcrum, and is horizontally covered above the lamination platform, the upper part of the middle line position of the lamination platform in the vertical direction is the fulcrum for pulling out the diaphragm belt from left to right, the lower part of the middle line position of the lamination platform is the clamping point of the diaphragm belt clamped by the diaphragm pulling mechanism, and the clamping point needs to be inclined by a certain angle in the process of moving to the left side or the right side of the lamination platform, so the actual pulling direction of the diaphragm belt, namely the length of the film, is the length from the fulcrum to the left side point or the right side point of the lamination platform.
