The invention relates to the technical field of seam tracking and discloses a laser weld seam tracking sensor based on dual-camera image overlaying. The sensor comprises a casing with an opening downwards, a main view camera, an auxiliary camera, a laser driver and a laser. The laser driver is fixed on the upper portion on the inner side of the casing, a main view camera support is fixed in the middle on the inner side of the casing, the main view camera is fixed on the main view camera support, and a narrow band filter with the same wave length with the laser is fixed on the front side of a lens of the main view camera; the laser support is fixed on the lower portion on the inner side of the casing, and the laser is fixed on the laser support. According to the laser weld seam tracking sensor, the structure is reasonable and compact, the usage is convenient, and automatic tracking of V-shaped weld seams and butt-joint gapless weld seams is achieved through matched usage of the laser driver, the main view camera, the laser and the auxiliary camera. The sensor has the advantage of being good in tracking efficiency, and the weld efficiency and the weld quality are improved.
Description
technical field [0001] The invention relates to the technical field of seam tracking, and relates to a laser seam tracking sensor based on dual-camera image compounding. Background technique [0002] At present, most of the welding of pressure vessels and pressure pipes in China still adopts manual or mechanized welding methods, which have the problems of harsh working conditions and high work intensity. Seam forming, welding efficiency and welding quality all need to be improved. At the same time, because the laser seam tracker currently on the market has the problem that the deformation of the V-shaped groove becomes smaller after filling, and the tracking effect is not ideal. At the same time, due to the butt gapless weld, the laser stripe has no deformation on this weld, and the general laser weld tracking sensor cannot be used. Contents of the invention [0003] The present invention provides a laser seam tracking sensor based on double-camera image composite, ...
