Abstract

The invention provides a device and a method of pressing a welding ring of an electrode pin. The device comprises a welding ring pickup device 1, an extrusion module 2, a spring table 3 and a groove 4, wherein the welding ring pickup device 1 is partially sleeved in the extrusion module 2, the extrusion module 2 is used for extruding the welding ring 5 positioned on the spring table 3, and the spring table 3 is arranged in the groove 4. Each of two sidewalls of the groove 4 comprises a roller 6 for shaping the edge of the extruded welding ring 5.

Description

technical field [0001] The invention belongs to the field of electrode packaging, and in particular relates to a pressing device and method for welding rings of electrode pins. Background technique [0002] IGBT (Insulated Gate Bipolar Transistor) is a new type of power device, which combines the dual advantages of power MOSFET (Metal-Oxide-Semiconductor-Field-Effect Transistor) and bipolar devices, with high input impedance, voltage control, input drive power Low power consumption, small on-resistance, simple control circuit, high voltage resistance, large current capacity, and fast switching speed are internationally recognized as the most representative products of the third revolution of power electronics technology. The sixth generation, commercialization has developed to the fifth generation. At present, IGBT has been widely used in AC motors, frequency converters, switching power supplies, lighting circuits, traction drives and other fields. [0003] Most of the IGB...
