Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery production, and particularly relates to a soft-pack lithium battery automatic packaging equipment and a production line thereof. BACKGROUND

[0002] Lithium batteries are a kind of batteries using lithium metal or lithium alloy as positive and negative materials, and using non-aqueous electrolyte solution, wherein the lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries, the lithium metal battery is generally a battery using manganese dioxide as a positive material, metal lithium or its alloy metal as a negative material, and using a non-aqueous electrolyte solution, while the lithium ion battery is generally a battery using lithium alloy metal oxide as a positive material, graphite as a negative material, and using a non-aqueous electrolyte, the lithium ion battery does not contain metal lithium, and is chargeable.

[0003] The soft-pack lithium battery belongs to a kind of lithium battery, and generally refers to a lithium battery packaged with an aluminum-plastic composite film, the soft-pack lithium battery has the characteristics of light weight and high safety, when a safety hazard occurs, the soft-pack lithium battery will only have a bulge and rupture, and will not have a violent explosion.

[0004] The existing soft-pack lithium battery needs to cut the aluminum-plastic film sheet to form the required specification during the production process, and needs to press the aluminum-plastic film sheet into shape, during the pressing process, a cell film groove is formed on the surface of the aluminum-plastic film sheet, so as to facilitate the subsequent placement of the battery cell in the cell film groove, and the aluminum-plastic film sheet is folded in half, so that the aluminum-plastic film sheet completely wraps the cell in the cell film groove, and finally the aluminum-plastic film sheet is sealed and packaged, while the existing soft-pack lithium battery mostly needs manual feeding and manual folding during the production process, the manual feeding method cannot guarantee the consistency of the position of the aluminum-plastic film and the cell during continuous production, and the manual folding cannot ensure that the aluminum-plastic film sheet is folded along the center line, if the folding line deviates, it will affect the battery production quality, easily damage the cell, and cannot guarantee the packaging of the aluminum-plastic film sheet, therefore, the manual feeding and the manual folding not only slow down the work efficiency, but also affect the production quality due to the inability to ensure the placement position and the folding position.

[0005] With reference to the Chinese patent application No. CN109216593B, the patent name is "a soft package lithium battery aluminum plastic film packaging equipment and aluminum plastic film automatic packaging process", the technical solution discloses "a soft package lithium battery aluminum plastic film packaging and rolling machine and aluminum plastic film packaging and rolling method, including support bottom plate, placing rack, pressure supporting chain and flattening device, the support bottom plate is installed on the upper end face of the middle part, the placing rack is provided with a square groove on the right end rear side, the support bottom plate is provided with a pressure supporting chain on the front and rear ends, and the pressure supporting chain is located outside the placing rack, and the flattening device is installed on the left end top of the placing rack", although the technical solution can effectively solve the problems that the rotation point of the aluminum plastic film will be displaced when folding, and the positions of the left and right ends of the aluminum plastic film are deviated when packaging, but the technical solution cannot realize the automatic and smooth folding action of the battery aluminum plastic film and the stable placing action of the battery cell, and the battery cell will be damaged when rolling the aluminum plastic film, which affects the production quality of the battery, and the technical solution can only realize the packaging production of single battery aluminum plastic film and battery cell in single station, which affects the production efficiency.
