IGBT module electrode bending locating tool, equipment and using method

Abstract

The invention discloses an IGBT module electrode bending locating tool which comprises a bending equipment base connected with electrode bending equipment and a locating bottom disc arranged above the bending equipment base. Four locating pins are arranged on the upper surface of the locating bottom disc corresponding to the positions of mounting through holes in the four corners of an IGBT module bottom plate. A cross-shaped steering pin which protrudes downwards is arranged at the diagonal line intersection point of the bottom of the locating bottom disc. A cross groove with the corresponding size is formed in the bending equipment base corresponding to the steering pin. The invention discloses the IGBT module electrode bending equipment which comprises the IGBT module electrode bending locating tool and a using method of the bending equipment. A locating part is arranged so that an IGBT module can be kept stable and cannot move when being subjected to electrode bending, and the production quality of the IGBT module is guaranteed.

Description

technical field [0001] The invention belongs to the field of electronic manufacturing, in particular to a tool for positioning IGBT modules. Background technique [0002] IGBT (Insulated Gate Bipolar Transistor), Insulated Gate Bipolar Transistor, is a composite full-control voltage-driven power semiconductor device composed of BJT (Bipolar Transistor) and MOS (Insulated Gate Field Effect Transistor). [0003] After the IGBT module is perfused with gel and the top cover is installed, the electrodes must be bent to facilitate subsequent module installation. The electrode bending requires that the height of each group of electrodes is consistent after bending, and the electrode surface coating is intact without scratches. The quality of electrode bending has an important impact on the appearance and subsequent use of the module. Therefore, accurate bending of various modules is an important process in the production of IGBT modules. [0004] When the electrode is bent, the ...

AI Technical Summary

Problems solved by technology

For electrodes of different heights and sizes, it can be solved by adjusting the height of the bending tooling or replacing the bending tooling. However, for modules with different bending directions for each group of electrodes, the bending tooling can only move to the Move in the same direction for electrode bending. After completing a group of electrodes in the same direction, you need to turn the module to reposition and orientate, and then perform bending operations on another group of electrodes. In this way, the module is repeatedly picked, placed, positioned, Orientation operation, that is, it is difficult to ensure the accuracy of positioning and orientation, which also seriously affects work efficiency
