Laser calibration method and device for spray gun

Abstract

The invention discloses a laser calibration method and device for a spray gun. The method comprises the steps: acquiring the projection position of a laser beam of a laser emitter on a target; judgingwhether the projection position is in a target area or not; and if the projection position is in the target area, enabling the spray gun to executesspraying operation. Before spraying operation of the spray gun is started, whether the spray gun executes the spraying operation or not is controlled by judging whether the projection position of the laser beam of the laser emitter on the target is inthe target area or not, the initial position of the spraying operation of the spray gun is calibrated, and the situation that the spraying effect is poor and the spraying raw materials are wasted dueto the fact that the initial position of the spraying operation of the spray gun is wrong is avoided; and the yield of the to-be-sprayed component is increased.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a laser calibration method and device for a spray gun. Background technique [0002] In the prior art, spraying technology is one of the key technologies of modern material surface engineering. Spraying technology is a process of spraying the coating material onto the surface of the base material through a spray gun with high-speed airflow to form a coating. With the development of science and technology, the spraying method has changed from the original hand-held spray gun to the automatic control spraying method of the mechanical hand-held gun, which has greatly improved the coating quality, production stability and efficiency. In the automatic control spraying mode of the mechanical handheld gun, it is necessary to set the spraying program in advance before the actual spraying, and plan the trajectory of the jet center sprayed by the spray gun on the wor...

Problems solved by technology

[0003] At present, to judge the starting position of the spray gun spraying operation, the pre-spraying test is generally used to judge and calibrate with the naked eye. However, the naked eye judgment has many subjective factors and takes a long time. The judgment of the starting position of the spray gun spraying operation often has large errors, which is extremely To a large extent, it affects the implementation of spraying process and the quality of coating products
