Title:
MACHINING APPARATUS HAVING MULTIPLE PULSE WIDTH LASER, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/035395
Kind Code:
A1
Abstract:
The present application relates to a machining apparatus having a multiple pulse width laser, and a method. The apparatus comprises: a multiple pulse width laser output assembly, a jet nozzle, an ultrasonic vibration assembly, a machining platform, and a controller; the controller is separately electrically connected to the multiple pulse width laser output assembly, the jet nozzle, and the ultrasonic vibration assembly; the machining platform is used for placement of a workpiece to be machined; the multiple pulse width laser output assembly is arranged above a material placement surface of the machining platform; the multiple pulse width laser output assembly comprises: a first laser emission device, a second laser emission device, and a beam coupling device; the beam coupling device is used for coupling lasers emitted by the first laser emission device and the second laser emission device and forming a laser beam of a common path; the jet nozzle is arranged at a side of the machining platform, and the jet nozzle faces the machining platform; the ultrasonic vibration assembly is arranged below the material placement surface of the machining platform and drives the machining platform to vibrate by means of ultrasonic waves. A solution provided in the present application can achieve highly efficient and damage-free machining.
