Abstract

The invention discloses a welding tool for a power module and belongs to the technical field of power module manufacturing. The welding tool comprises a copper base plate positioning tool, a copper-clad plate positioning tool and a power terminal positioning tool, wherein the copper base plate positioning tool comprises a rectangular base plate, two first baffle plates and second baffle plates andis used for positioning the copper base plate of the power module; the two first baffle plates are located at two long edges of the base plate separately; the second baffle plates are located at twoshort edges of the base plate separately; the copper-clad plate positioning tool comprises two third baffle plates which are fixed on the two first baffle plates separately; a plurality of bumps are arranged on opposite side walls of the two third baffle plates respectively; a copper-clad plate of the power module is arranged between the two third baffle plates; and the power terminal positioningtool is connected across the two second baffle plates. The welding tool has the beneficial effects that a welding tool body comprises three assemblies and is easy to assemble, and the production efficiency is improved; and the bumps are arranged on the side walls of the copper-clad plate positioning tool, and the copper-clad plate is fixed by adopting a point contact mode, so that the tool is moreconvenient to dismantle after being welded, and the problem that an adhesive substance is not easy to dismantle is solved.

Description

technical field [0001] The invention relates to the technical field of power module manufacturing, in particular to a power module welding tool. Background technique [0002] The power module (Intelligent Power Module, IPM) is a power drive product that combines power electronics and integrated circuit technology. IPM integrates power switching devices and high-voltage drive circuits, and has built-in fault detection circuits such as overvoltage, overcurrent and overheating. On the one hand, the IPM receives the control signal from the MCU to drive the subsequent circuits to work, and on the other hand, sends the system status detection signal back to the MCU. IPM wins more and more markets with its advantages of high integration and high reliability. It is especially suitable for frequency converters and various inverter power supplies for driving motors. An ideal power electronic device for home appliances. [0003] A power module generally includes a copper clad lamina...
