Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing:
[0017] The battery connection pole piece manufacturing method disclosed by the present invention comprises the following steps:
[0018] S1: Copper plate is used as stamping raw material, and a protective film is attached to one side of the plate;
[0019] S2: Put the plate in the plating tank of the electroplating solution and tin-plate the surface without the protective film;
[0020] S3: Tear off the protective film to ensure that the surface with the protective film is not tinned;
[0021] S4: The surface of the copper plate torn off the protective film is stamped and blanked to form the battery connection pole piece.
[0022] The tin-plated surface of the present invention is the side where the battery pole piece is connected to the battery top cover, and the thickness of the tin-plated layer is not less than 7um. In this embodiment, the thickness of the tin-plated l...

Abstract
The invention relates to a battery connection pole piece manufacturing method. The method includes steps: (1) using copper plates as stamping materials, wherein one surface of each plate is coated with a protective film; (2) putting the plates in an electroplating bath to realize tinning of the surfaces without the protective films; (3) tearing off the protective films, and guaranteeing that the surfaces with the protective films are not tinned; (4) subjecting the surfaces, with the protective films torn off, of the copper plates to stamping, blanking, forming and processing to obtain battery connection pole pieces. The battery connection pole piece manufacturing method has the advantages that direct welding of the connection pole pieces and battery top caps can be guaranteed, insufficient solder is avoided, flux assisted soldering procedures such as brushing of soldering paste are omitted, soldering paste brushing personnel and soldering paste purchase cost are saved, adhesion of resistance welding pins of the pole pieces to tin layers is avoided, polishing frequency of the welding pins is reduced, and production efficiency is improved.
Description
technical field [0001] The invention relates to the field of battery resistance welding, in particular to a method for manufacturing battery connecting pole pieces. Background technique [0002] At present, the resistance welding of the battery connecting the pole piece and the top cover requires auxiliary processes such as brush solder paste and other fluxes to realize the welding of the pole piece and the battery top cover without false welding. However, if the connecting pole piece is tinned on both sides, the auxiliary process of flux such as brushing solder paste is cancelled, and the battery top cover is resistance welded, the following situations usually occur: the welding cannot be done; although it is welded, the welding is unstable and there is a false weld ; Solder pins adhere to the tin layer, the number of grinding times is high, and the welding efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a method f...
