Problems solved by technology
[0003] This detection method is highly subjective and cannot be measured by quantitative standards, so the accuracy and consistency of the detection results are low
In addition, the liquid used in the detection process will also cause pollution to the spray gun and the environment, which is not conducive to the transportation and storage of the spray gun

The invention discloses a spraying pressure field scanner for an air spraying gun. The spraying pressure field scanner comprises a mobile panel, an electric cylinder, a plurality of pressure sensors, a controller, a data acquisition card and an industrial personal computer, wherein the electric cylinder is connected with the mobile panel; a servo motor drives the electric cylinder to drive the mobile panel to move; a plurality of pressure measurement holes are formed in the mobile panel; each pressure measurement hole is connected with one pressure sensor; the signal output ends of the pressure sensors are connected with the data acquisition card; the data acquisition card is connected with the input / output port of the industrial personal computer and the signal input port of the controller; and the output port of the controller is connected with the servo motor. By the spraying pressure field scanner for the air spraying gun, the spraying effect of a paint spraying gun can be analyzed and judged more accurately and objectively according to quantized data, and the detection accuracy and efficiency can be improved effectively; furthermore, pollution to the spraying gun and the environment during detection can be eliminated, and transportation and storage of the spraying gun are facilitated. The invention also discloses a method for detecting an effective spraying active region of the spraying gun.
Description
technical field [0001] The invention relates to a detection tool for an air spray gun, in particular to an air spray gun spraying pressure field scanner. The invention also relates to a method for detecting the spraying effective area of the air spray gun. Background technique [0002] The air spray gun is a spraying tool that atomizes the paint into fine paint droplets by compressed air, and sprays it on the surface of the object to be coated under the airflow. The scope and shape of the effective area sprayed by the air spray gun is a key indicator of the performance of the spray gun, so the spray gun needs to be tested before leaving the factory. The existing detection method is the test spraying method, that is, spraying with a liquid with a certain viscosity instead of the sprayed paint, and observing the shape of the spraying effective area and the spraying effect with human eyes, so as to judge whether the spray gun is qualified. [0003] This detection method is ...
