Welding process for battery terminal assembly

Abstract

The invention provides a welding process for a battery terminal assembly. The welding process comprises the following steps of: providing a ceramic plate and a terminal group; preparing a tin ring; pre-assembling the terminal group and the ceramic plate to form a pre-assembled structure, wherein the pre-assembled structure has a to-be-welded position; feeding the tin ring to the to-be-welded position; and carrying out welding to obtain the battery terminal assembly. According to the welding process provided by the invention, the tin ring is prepared, the tin ring is arranged at the to-be-welded position of the pre-assembled structure formed by pre-assembling the ceramic plate and the terminal group, and the tin ring at the to-be-welded position is welded, so that the ceramic plate and theterminal group are assembled to form the battery terminal assembly; and therefore, the proper tin ring size can be manufactured according to the structural sizes of the ceramic plate and the terminalgroup, the tin amount of small product welding is effectively ensured, the welding yield is improved, and the welding time is shortened.

Description

technical field [0001] The invention relates to the technical field of battery terminal assembly welding, in particular to a battery terminal assembly welding process. Background technique [0002] The existing welding method usually adopts solder wire welding method, that is, the tip of the soldering iron is placed at a certain angle and placed on the PIN pin and pad of the acoustic component, and the PIN pin and pad are heated by the soldering iron tip; at the same time, the solder wire is fed from one side. Put it in, send it to the soldering iron tip and PIN pin, under the heat conduction of the soldering iron, the solder wire melts, and flows with the melting of the tin wire, and finally realizes the wrapping of the entire PIN pin and the pad, and then removes the solder wire and soldering iron tip to complete the welding. However, this soldering method is applied to small-structure products. On the one hand, the amount of tin cannot be guaranteed, so that the height of...

Problems solved by technology

However, this soldering method is applied to small-structure products. On the one hand, the amount of tin cannot be guaranteed, so that the height of the tin spot after soldering of the product often exceeds the height of the PIN pin, resulting in that the product cannot meet the assembly requirements in a very small assembly space; on the other hand On the one hand, limited by the small structure of the product and the control height of the amount of tin, it is impossible to realize one-time soldering, resulting in too long soldering time, which ultimately makes it difficult to guarantee the soldering yield
