Title:
MICRO-PART SURFACE MODIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/137773
Kind Code:
A1
Abstract:
The present invention provides a micro-part surface modification device, comprising a strengthening module, a roll-to-roll vibration piece module, a water supply module and a laser module. The strengthening module comprises a shell and shots, a work cavity being arranged in the shell. A movable vibration piece is installed in one end of the work cavity, a plurality of shots being evenly distributed on the vibration piece. A workpiece to be strengthened is installed in the other end of the work cavity. The roll-to-roll vibration piece module is used for driving the vibration piece to move. The water supply module is used for forming a constraint layer on a side of the vibration piece. The laser module is used for generating a laser beam, which passes through the constraint layer to impact the vibration piece, so that the vibration piece vibrates for providing kinetic energy for the shots, the shots that obtains the kinetic energy being used for impacting the workpiece to be strengthened. In the present invention, a high-energy nanosecond pulse laser-induced shock wave is used for impacting the vibration piece, which drives micro shots to continuously impact the surface of a micro-part to perform modification treatment. The device has a simple structure and good reliability.
