Spraying method for spraying developing agent on surface of part

Abstract

The invention discloses a spraying method for spraying a developing agent on the surface of a part. The spraying method comprises the following steps: A, preparing the developing agent; B, automatically spraying a developing agent on the surface of the part through a spray gun connected with a driving device, wherein B comprises the steps that B1, the spray gun is moved to the position above the part, and the vertical distance between the working plane of the spray gun and the lowest point of the to-be-sprayed face of the part is set to range from 150 mm to 210 mm; B2, the air pressure for controlling the open-loop flow of the spray gun is set to be 0.5-0.9 bar; B3, the air pressure of the fixed spraying area for controlling the spraying gun is set to be 1.5-2.5 bar; B4, the air pressure for controlling the atomization parameter of the developing agent is set to be 1.0-1.5 bar; and B5, the spray gun is moved above the part for spraying, and the moving speed is 200-400 mm / min. According to the spraying method for spraying the developer on the surface of the part, the spraying efficiency can be improved, the spraying thickness is uniform, and the spraying effect is good.

Description

technical field [0001] The invention relates to the technical field of blue light scanning measurement, in particular to a spraying method for spraying developer on the surface of parts. Background technique [0002] The blue-ray scanning measurement system adopts the principle of non-contact optical measurement, realizes point cloud acquisition through grating projection, and is equipped with moving mechanisms such as robots, guide rails, and turntables to achieve large-scale flexible measurement. High-density point cloud measurement can truly restore the richness of objects. Surface details. When the measuring grating is working, the photoelectric sensor emits light to the surface of the detected part, and the light absorbed by the part causes the light intensity received by the receiver to change, and the change value triggers the output of the light-on signal to realize the detection function. [0003] However, due to the bright surface of the machined parts, it is not ...

Problems solved by technology

[0003] However, due to the bright surface of the machined parts, it is not conducive to the measurement of the surface of the part by the blue light scanning measuring instrument. It is necessary to spray a developer on the surface of the part. The developer can make the latent image produced by the photosensitive material exposed into a visible image.

Generally, the method of spraying the developer on the surface of the parts is manual spraying. It is difficult to make the coating on the surface of the parts uniform by manual spraying. Phenomenon, in addition, manual spraying takes a long time and is inefficient
