Abstract

The invention discloses welding seam tracking and detecting equipment. The equipment comprises an imaging device, a structured light generator and an optical device, wherein the imaging device is used for imaging a welding seam; the structured light generator is used for generating structured light; and the optical device can reflect and refract light so as to split the structured light emitted from the structured light generator into refracted light and reflected light which irradiate to the welding seam. By using the welding seam tracking and detecting equipment of the invention, a structured light splitting effect is achieved by adopting the reflection and refraction properties of the optical device, so as to split the structured light, and detect and track a curve welding seam with complex shapes.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a seam tracking detection device. Background technique [0002] In the field of automatic welding, since the operator is not suitable to enter the welding work area, it is impossible to closely monitor the welding process in real time and make necessary adjustments and controls. Changes in factors such as dimensional errors and position deviations and workpiece heating deformation will cause the position of the joint to deviate from the predetermined path, which will lead to a decrease in welding quality or even failure. Therefore, accurate seam tracking is the key to ensure welding quality. [0003] In the prior art, structured light seam tracking sensors are widely used to track and detect welds. Traditionally, single-line structured light seam tracking sensors are commonly used, so they can only be used for tracking and detecting linear seams. For curved welds, multi-line ...
