AI Technical Summary

Technical Problem

During the chip surface scratching process, the end point of the glue gun coincides with the starting point, resulting in an increase in the amount of glue, and may cause glue to overflow during the cap, affecting signal transmission and cap stability.

Method used

An IGBT pin plug device is designed, using a positioning member and a scratching device. Through the coordination of the limit block of the positioning member and the rectangular groove, the scratching head is ensured to move along the circumference of the outer wall of the positioning member, avoiding the glue flowing to the pin direction, and removing the glue at the overlap between the end point and the starting point when the positioning member is disengaged.

Benefits of technology

It effectively avoids the overflow of glue during the cap, ensures the integrity of signal transmission and the stability of the cap, and prevents the glue from flowing towards the pin direction, ensuring the correct installation of the pin.

Abstract

The invention belongs to the technical field of electrical elements, and particularly relates to equipment for processing semiconductors, in particular to IGBT (Insulated Gate Bipolar Translator) pin equipment and an assembly process thereof. The invention provides IGBT pin insertion equipment, and the equipment comprises a pin insertion device which is rotatably disposed on a workbench; the glue scratching device is arranged on the workbench and is suitable for scratching glue on the surface of the workpiece; the positioning piece is located on the surface of the workpiece; wherein the workpiece carrying the positioning piece is moved to a pin inserting station, and the pin inserting device is suitable for inserting a pin on the workpiece; the workpiece is moved to a glue scratching station, and a glue scratching head of the glue scratching device moves in the circumferential direction of the outer wall of the positioning piece so that the surface of the workpiece can be coated with glue; after glue scratching is finished, the positioning piece moves upwards to be separated from the workpiece, and the positioning piece is suitable for removing glue at the overlapped position of the end point and the starting point in the glue scratching process; and through the arrangement of the positioning piece, the glue at the overlapped part of the end point and the starting point can be prevented from overflowing during cover sealing in the glue scratching process.
