Title:
DETECTION ASSEMBLY, LASER MODULE, LASER EMISSION CONTROL METHOD, AND LASER PROCESSING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2024/078058
Kind Code:
A1
Abstract:
The present application relates to a technique field of laser processing, aiming to solve problem of lens defects or impurities affecting normal laser emission during laser processing or causing excessive absorption of laser energy by the lens. The application discloses a detection assembly, laser module, laser emission control method, and laser processing equipment. The detection assembly includes a first circuit board. The first circuit board includes a substrate and a temperature sensor. The substrate is provided with a first via allowing laser emitted by the laser generator to pass. The temperature sensor is positioned on a surface of the substrate outside the first via and is directly or indirectly thermally coupled to a to-be-inspected lens located in a laser path of the laser generator. The beneficial effect of the present application is the ability to detect the temperature of the lens conveniently without affecting the laser emission.
