Lithium battery assembly method, assembly system and positive and negative homopolar explosion-proof lithium battery

A lithium battery assembly method, comprising the following steps of:

• (1) arrangement of an assembly system:
• the assembly system consists of an electrode assembly system, a combining system and a sealing system;
• (2) ejection:
• the electrode assembly system comprises a nailing machine and a nailing machine control module which are configured to correct guide pins and drive the guide pins to enter pre-punched holes of a nailing area to achieve nailing;
• (3) winding:
• the electrode assembly system further comprises a winder and a winder control module which are configured to perform primary foil pulling, flattening, secondary foil pulling and foiling on foil paper, wind tails of the guide pins after ejection, and perform synchronous lamination, paper cutting, gumming and output;
• (4) assembly:
• the combining system comprises a combiner and a combining controller;
• an aluminum shell is fixedly connected with the positioned guide pins and hence forced by program control;
• the guide pins are extended horizontally to form an electrode;
• and the seamless fixed connection between the guide pins and the aluminum shell is achieved to form a battery body structure;
• and
• (5) sealing:
• the sealing system comprises a sleeve device and a sealing machine and further comprises a full-servo control system and a control device;
• the battery body structure is sleeved into a tubular gel according to the setting scale of the control device;
• and the displacement and the moving cycle are calibrated by the servo control system to control the sealing machine to achieve port sealing.
