Description

Battery core made slide way alternate lamination platform and lamination diaphragm pressing process thereof
Technical Field
The invention relates to the field of manufacturing of lithium ion power batteries, in particular to a slide rail alternate lamination platform manufactured by a battery core and a lamination diaphragm pressing process thereof, which are used for automatic battery core lamination manufacturing.
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. The existing battery core manufacturing process comprises two modes of strip lamination and single lamination according to different diaphragm inserting processes, namely, continuous diaphragms and single 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, a strip diaphragm is circularly pulled back and forth above the lamination platform, the positive pole piece or the negative pole piece is covered on the surface of the positive pole piece or the negative pole piece after being laminated, and then the diaphragm is cut; this kind of lamination mode, belt form diaphragm tensioning and by the round trip pulling in the lamination process, there is stress inside, and the diaphragm surface can appear wrinkling the circumstances such as after deciding, influences electric core quality. For the single-chip lamination process, the diaphragm is firstly cut into a single-chip structure before lamination, the single-chip diaphragm is laminated on the surface of the positive plate or the negative plate after the positive plate and the negative plate are laminated, the lamination process needs to take the diaphragm for multiple times to laminate the diaphragm, so that the lamination efficiency is low, the diaphragm needs to be aligned before lamination to ensure the position precision of lamination at each time, and the lamination position precision is difficult to effectively ensure.
Aiming at the strip lamination process, the following technical difficult problems need to be solved in the process of automatic lamination design: in the lamination process, after a continuous diaphragm belt is pulled open, a positive plate or a negative plate is laminated on the diaphragm belt, then the diaphragm is pulled open reversely to the positive plate or the negative plate, the diaphragm belt is coated with films back and forth along a Z-shaped path from left to right, and the pole pieces with different polarities are sequentially laminated on the diaphragm; based on the lamination principle, the horizontal diaphragm covered on the lamination platform needs to be pressed in the left and right lamination processes of the diaphragm so as to avoid lifting the diaphragm during subsequent film drawing. The traditional film pressing mechanism generally drives a pressing sheet in a suspended state through an air cylinder to press a diaphragm from the outer side of a lamination platform, and because interference with movement of a film is also required to be avoided in the film pressing process, the pressing sheet cannot be pressed downwards only from the vertical direction in the film pressing process, and the pressing sheet also needs to have retraction force in the horizontal direction; for realizing the requirement, the existing film pressing device adopts a cam transmission mode to realize the driving in the vertical direction and the horizontal direction, the transmission is unstable, the flatness during the film pressing of a pressing sheet is influenced, the structural design is very complicated, the force transmission path is long, and the transmission error is large.
