Background
Lithium battery Lithium battery refers to a battery containing lithium in an electrochemical system including metallic lithium, lithium alloys, and lithium ions, lithium polymers. Lithium batteries can be broadly divided into two categories, lithium metal batteries and lithium ion batteries. A lithium battery is a rechargeable battery that operates primarily by means of lithium ions moving between a positive electrode and a negative electrode. Batteries that generally employ materials containing lithium as electrodes are representative of modern high performance batteries. With the development of new energy driven by China, the requirements of various industries on lithium ion power batteries are increasing, and the battery core in the composition structure of the lithium ion power batteries is a core component of the lithium ion power batteries, and the battery core is generally formed by mutually staggered and overlapped positive and negative pole pieces. The battery cell composition structure comprises a plurality of positive and negative plates which are overlapped up and down in a staggered way, and the positive and negative plates are isolated and insulated through a diaphragm. The lithium battery equipment with advanced domestic technology is mainly mastered in foreign equipment suppliers, and domestic high-end lithium battery lamination equipment is mainly imported at present.
The battery core of the lithium ion battery is generally formed by overlapping positive and negative plates in a staggered way, and an insulating diaphragm is also required to be inserted between the positive and negative plates. The current manufacturing process of the battery cell comprises two modes of strip lamination and single-sheet lamination according to the different diaphragm inserting processes, namely continuous diaphragm lamination and single-sheet diaphragm lamination are adopted during lamination. For the strip lamination process, positive and negative pole pieces are alternately placed on a lamination platform during lamination, strip diaphragms are circularly pulled back and forth above the lamination platform, the surfaces of the positive pole pieces or the negative pole pieces are covered after the positive pole pieces or the negative pole pieces are overlapped, and then the diaphragms are cut. For the single-sheet lamination process, the diaphragm is cut into a single-sheet structure before lamination, after the positive and negative plates are stacked, the single-sheet diaphragm is stacked on the surface of the positive plate or the negative plate to realize lamination, and the diaphragm lamination process needs to take the diaphragm for multiple times, so that the lamination efficiency is low, the diaphragm is required to be aligned before lamination for ensuring the position precision of each lamination, and the position precision of the lamination is difficult to effectively ensure.

In order to meet the requirement, the conventional film pressing device adopts a cam transmission mode to realize driving in the vertical direction and the horizontal direction, the transmission is unstable, the flatness during film pressing of the film pressing is influenced, the structural design is very complex, the force transmission path is long, and the transmission error is large.
