Detection method and system of surface thickness and planeness of rotary target

Abstract

The invention relates to the field of surface spraying and discloses a detection method and system of surface thickness and planeness of a rotary target. A distance measuring module moves synchronously along with a spraying gun in the axial direction of the rotary target; the distance measuring module is used for detecting a distance l between a certain point of the surface of a coating and the distance measuring module in real time; the distance measuring module is used for transmitting measured data to a data processing module; and the data processing module is used for calculating the thickness of the surface coating in real time according to an equation h=L-r-1. According to the detection method and system, disclosed by the invention, the surface thickness or the planeness of the rotary target can be detected in real time in a spraying production process of the rotary target, so as to avoid a condition that the thickness or the planeness of the surface coating is detected manually by halting is avoided, and a surface spraying speed is not influenced; manual errors, introduced by manual detection, can be avoided by adopting an optical detection module to detect the surface of the rotary target in real time, and the detection precision and the detection accuracy are improved; and a non-contact type detection manner of optical detection is adopted, so that the surface of the detected coating is not damaged, and the surface quality of the coating is not influenced.

Description

technical field [0001] The invention relates to the field of surface spraying, in particular to a detection method and detection system for the surface thickness and flatness of a rotating target. Background technique [0002] In order to protect the surface of the rotating target from corrosion or to have certain characteristics, the target is generally sprayed onto the surface of the rotating target by spraying technology. The deposition thickness of each spraying target is generally 20-50 microns. If it is necessary to spray a target with a thickness of 6mm-20mm on the surface of the rotating target, the spray gun needs to be sprayed back and forth 50-500 times, so that the spraying process generally lasts 10-20 Hour. [0003] Due to the long spraying process, the raw materials, working air pressure, powder feeding amount, mechanical walking parameters and external factors during the spraying process will all affect the surface quality and spraying efficiency of the spra...

Problems solved by technology

At present, the method of detecting the thickness of the target is to stop the machine, and use random sampling on the sprayed target to measure the thickness of the target. However, this detection method cannot directly reflect the thickness of the sprayed target on the entire rotating target; and manual detection is used. It is easy to introduce errors, and the shutdown detection will affect the efficiency of spraying production and increase the cost of spraying

In addition, during the spraying production process, the high-energy particle flow will emit a strong glow, making it difficult to directly detect the thickness of the spraying target
