The invention provides a battery pole piece production method and battery pole piece production equipment, belonging to the technical field of battery pole piece processing. The method comprises the following steps that a lug welding mechanism, a lug welding driving mechanism, a protective glue pasting mechanism and a protective glue pasting driving mechanism which are sequentially arranged in a pole piece conveying direction are provided, the lug welding driving mechanism is used for pulling a pole piece so as to allow the pole piece to pass through the lug welding mechanism, and the protection glue pasting driving mechanism is used for pulling the pole piece so as to allow the pole piece to pass through the protection glue pasting mechanism; and the pole piece welding driving mechanism and the protective glue pasting driving mechanism are controlled to drive the pole piece to advance by one piece length at the same time, so the welding position of the pole piece moves to the welding station of the pole piece welding mechanism, and meanwhile, the glue pasting position of the pole piece moves to the glue pasting station of the protective glue pasting mechanism. According to the invention, the two driving mechanisms are started and stopped at the same time, the counter weight of a buffer compensation mechanism can only provide tension of the pole piece, the starting inertia of the pole piece is greatly reduced, a belt conveying speed can be greatly increased, takt time is shortened, and a belt breaking risk is reduced.
Description
technical field [0001] The invention relates to the technical field of battery pole piece processing, in particular to a battery pole piece manufacturing method and equipment. Background technique [0002] Before the battery roll is wound, first use the sheet-making equipment to weld the tabs on the positive and negative electrodes and paste the protective tape to complete the sheet-making work. [0003] Pole pieces usually need to go through welding lugs and multiple protective glue processes. After each process, there are buffer compensation mechanisms and driving tape mechanisms to ensure the continuous supply of tapes in each process. [0004] When working, the actions of each process are controlled independently, and the working actions of the welding tab and glue application process are independently controlled. The time difference between the actions of different processes is offset by the buffer compensation mechanism, and the length of the buffer compensation materi...
