Abstract

The embodiment of the invention provides power semiconductor lead frame production integrated equipment, and relates to the technical field of lead frame production and processing equipment. The power semiconductor lead frame production integrated equipment comprises a punching machine, a workpiece conveying mechanism and a workpiece cleaning mechanism. The workpiece conveying mechanism comprises a machine box, a partition plate, a discharging plate, a feeding conveying assembly, a discharging conveying assembly and a middle conveying assembly, the machine box is arranged on one side of the punching machine, and a feeding port and a discharging port are formed in the two sides of the machine box respectively. When the lead frame is conveyed by the feeding conveying assembly, the discharging conveying assembly and the middle conveying assembly, the first water pump operates, and the first water pump pumps a water source in the water tank through a water inlet pipe; a water source passes through a water outlet pipe and a V-shaped drainage pipe and is finally sprayed out from a first spray head to the lead frame transported above the feeding conveying assembly, the discharging conveying assembly and the middle conveying assembly, so that impurities on the surface of the lead frame are cleaned.

Description

technical field [0001] The present application relates to the technical field of lead frame production and processing equipment, and in particular, relates to an integrated production equipment for power semiconductor lead frames. Background technique [0002] Power semiconductor devices are mainly power metal oxide semiconductor field effect transistors, insulated gate bipolar transistors and power integrated circuits. The lead frame is a structural part that forms an electrical circuit by means of gold wire, aluminum wire, copper wire, etc. to realize the electrical connection between the lead-out end of the chip's internal circuit and the outer lead wire, and mainly serves as a bridge connection. Lead frames are mainly used in semiconductor integrated blocks, and are one of the important components in the production of electronic information technology. [0003] One of the production methods of the lead frame is to use a stamping machine for stamping and forming. After ...
