Problems solved by technology

[0002] With the national strategic policy of energy saving, emission reduction and green environmental protection, the company's full frequency conversion planning development direction, more and more frequency conversion products will become the company's mainstream; but its production process is complicated, and the production efficiency is low. In the production process of the core power device of the frequency conversion external unit, our company requires the positioning accuracy of the power module to be ≤±0.3mm, and the assembly method is fixed by the gasket tooling method, but tooling wear, foreign objects and other abnormalities will easily lead to abnormal positioning accuracy of the module, and reliability lower

Abstract

The invention provides a power device which comprises a power device body, wherein two ends of the power device body are fixedly provided with a plurality of pins, and the pins are provided with limiting bulges used for limiting the installation height of the power device body. The power device can be directly inserted into a PCB for welding and fixing production, which not only eliminates the positioning height of an original gasket tool, but also improves the production efficiency and the quality consistency of the production line.

Description

technical field [0001] The invention relates to the field of production technology of frequency converters, in particular to a welding positioning method for power devices. Background technique [0002] With the national strategic policy of energy saving, emission reduction and green environmental protection, the company's full frequency conversion planning development direction, more and more frequency conversion products will become the company's mainstream; but its production process is complicated, and the production efficiency is low. In the production process of the core power device of the frequency conversion external unit, our company requires the positioning accuracy of the power module to be ≤±0.3mm, and the assembly method is fixed by the gasket tooling method, but tooling wear, foreign objects and other abnormalities will easily lead to abnormal positioning accuracy of the module, and reliability lower. Contents of the invention [0003] In view of this, the ...
