Description

TECHNICAL FIELD

[0001] The present application relates to the field of filter BUSBAR welding, in particular to a filter BUSBAR welding tool. BACKGROUND

[0002] Filter BUSBAR assemblies play a crucial role in the commercial vehicle field, and their efficient and stable performance directly affects the operation of the vehicle's electrical system. With the continuous progress of commercial vehicle technology, the demand for high-power filter wireless charging systems is increasing, which prompts the manufacturing process of BUSBAR assemblies to develop towards higher precision and lower cost. However, the welding process of BUSBAR assemblies has become a key bottleneck in the manufacturing process due to its numerous parts, strict size requirements, and high welding difficulty.

[0003] In traditional BUSBAR welding processes, multiple independent welding tools are usually used to complete welding tasks in different positions. For example, special fixtures are designed to fix components such as copper bars and magnetic rings, and laser welding equipment is used to complete the processing of each welding point one by one. Specifically, common methods include using fixed fixtures to complete preliminary positioning with manual or semi-automatic operation, or using complex multi-axis mechanical arms to achieve dynamic welding. In addition, some solutions use a multi-station rotary platform combined with a specific fixture design to reduce the frequency of tool replacement. Although these methods meet production needs to some extent, they all have certain limitations.

[0004] The above traditional methods can solve the welding problem of BUSBAR assemblies to some extent, but still expose many defects in actual application. First, frequent tool replacement not only consumes a lot of time, but also increases the complexity of equipment debugging, resulting in low overall production efficiency. Second, high tool development costs and site investments further increase the economic burden on enterprises. In particular, in the case of welding multiple positions, existing technologies often struggle to achieve efficient and low-cost solutions, so there is an urgent need for a technical means that can simplify the welding process and reduce manufacturing costs.

[0142] The implementation principle of the filter BUSBAR welding tool according to the embodiment of the application is as follows: originally, six welding jigs are needed for a single BUSBAR component. Especially when there is only one high-power welding device, in order to complete the welding work at eight positions, the jigs need to be continuously replaced, and the laser welding parameters need to be debugged to complete the production of a single product. Most of the welding time is lost in replacing the jigs and debugging the parameters, and the efficiency is low and the cost is high.

[0143] The welding tool according to the application reduces the six welding jigs for a single BUSBAR component to two, greatly reducing the development jig cost, equipment cost and manufacturing cost.

[0144] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
