Battery pack with glued connection pieces, and fixing method of battery pack

Abstract

The invention relates to a battery pack with glued connection pieces. The battery pack comprises a plurality of batteries and the connection pieces used for connecting the batteries; the battery packis further provided with pasting glue used for attaching the connection pieces and formed by glue dispensing of a gluing agent; and the pasting glue is located between every two adjacent batteries. Afixing method of the battery pack comprises the following steps of designing an arrangement mode of the battery pack according to requirements; arranging the batteries orderly in the designed arrangement mode; dispensing glue between every two adjacent batteries; attaching and fixing the connection pieces to the batteries; and connecting the connection pieces with the batteries through welding. The connection pieces are fixed by pasting of the gluing agent, traditional complicated clamp welding is replaced, and attaching is performed through the method, so that full-automatic production can berealized, the production time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a battery pack with a glued connecting piece and a fixing method thereof, in particular to a battery pack with a glued connecting piece and a fixing method thereof, which relate to the application field of battery pack manufacturing. Background technique [0002] With the popularization of electronics and electrical appliances in the world today, we are inseparable from various electronic products that are convenient to use in our daily life, ranging from large cars and subways to small home appliances, computers, mobile phones, etc. can be accessed or used. Among the various electrical and electronic products, a large proportion of them are driven by the use of primary batteries or rechargeable batteries. The best example is the use of mobile phones. According to relevant survey statistics, the number of mobile phones used worldwide has exceeded 6 billion, which also reached 1.3 billion in China. At the same time, there are co...

Problems solved by technology

But once the power of the battery needs to be increased to become a power battery, the number of battery combinations will increase to tens to hundreds of digits. This means that the battery pack can no longer be welded by hand, and can only be done with the help of an automatic battery lap welding machine. Handle and pass the fixture to produce stable and qualified products

Before welding, it is necessary to first fix the battery connection sheet at an accurate position relative to the battery cell or the fixed bracket. The connection sheet should be close to the welding surface of each cell end, and no excessive gaps are allowed, otherwise it is easy to current during welding. Flashover will cause poor contact welding, which will directly affect the electrical performance of the battery pack and become a waste product; at the same time, special welding jigs need to be designed and connected according to each battery pack. One or more sets of special welding jigs must be prefabricated to fix the battery, and the jigs can directly Affect the welding quality of the entire battery pack. Once the position of the fixture is found to be inaccurate or there are problems with the assembly of the workpiece, the fixture needs to be redone, resulting in prolonged production time, increased production costs, and reduced production efficiency.
