Title:
WELDING TRAJECTORY TRACKING METHOD, METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/107336
Kind Code:
A1
Abstract:
A welding trajectory tracking system, method and device. The welding trajectory tracking system comprises a processor (10), a coherent light scanner (20), a photosensitive element (30), and a laser welding device (40). The coherent light scanner (20) is used for emitting a scanning beam and a reference beam coherent with each other, and performing coherent light scanning on a welding region, the coherent light scanning comprising at least one scanning line; the photosensitive element (30) is used for receiving an interference signal of the reflected light of the scanning beam and the reference beam, and sending the interference signal to the processor (10); the processor (10) is used for determining height information of the scanning line according to the interference signal, determining a welding trajectory according to the height information of the at least one scanning line, and generating a welding control signal according to the welding trajectory; the laser welding device (40) is used for positioning the welding trajectory according to welding control signal.
