The invention discloses an electric automobile lithium battery production apparatus. When the apparatus is used, an electrical core and a battery box are conveyed to an electrical core automatic-boxing machine through a conveyor belt, the electrical core automatic-boxing machine boxes the electrical core in the battery box to make a semi-finished battery, the semi-finished battery is conveyed through a third conveyor belt, and the assembling of the battery is completed by allowing the semi-finished battery to sequentially pass through an electric core press plate lateral screw installing machine, an electronic box overturning machine, a laser spot welder, a battery copper braid installing machine and a screw automatic-locking machine during the convey of the semi-finished battery on the third conveyor belt. The automatic group assembling streamline is used and all operations are reasonably arranged in the whole process, so automatic assembling is realized in the whole assembling process, and manpower at all stations is substituted by machines, thereby the battery grouping production efficiency is improved, and the product quality is guaranteed. The invention also discloses an electric automobile lithium battery production method.
Description
technical field [0001] The invention relates to the technical field of electric vehicle lithium battery production, in particular to an electric vehicle lithium battery production device and a production method thereof. Background technique [0002] At present, domestic electric vehicles are in the stage of accelerated development, and there are many power battery manufacturers, but the grouping technology is backward, mostly manual and semi-automatic, and the process level is relatively poor. [0003] At present, the battery group adopts semi-automatic production and assembly lines. Each production and assembly line is equipped with 10 stations, which are the pre-installation process of battery frame, the first process of battery assembly, the second process of battery assembly, the installation process of BMS board and pressure plate, The pre-installation and arrangement process of battery tabs, the installation process of positive and negative electrode series copper stri...
