Film thickness measurement system

Abstract

A film thickness measurement system comprises a measuring head, a mechanical arm, a robot control component and an upper computer, wherein the measuring head is suitable for measuring the film thickness of the measuring point on a workpiece to be measured so as to acquire a measurement signal associated with the film thickness; the measuring head is fixedly arranged on the mechanical arm; the robot control component is coupled to the measuring head and the mechanical arm, is suitable for carrying out data acquisition the measurement signal, and controls the motion of the mechanical arm according to a data acquisition result; and the upper computer is coupled to the robot control component. By using the film thickness measurement system, film thickness measurement time is short, a system response speed is fast, system cost is low and the system is good for maintenance.

Description

technical field [0001] The invention relates to the field of film thickness measurement, in particular to a film thickness measurement system. Background technique [0002] At present, more and more industries need to apply film thickness measurement systems, such as the automotive industry. The film thickness measurement system can quickly measure the thickness of the film layer coated on the workpiece. For example, the workpiece can be the coating of a painted car to determine whether the coating meets the standard, so as to make a decision based on the measurement results. Subsequent judgment. If classified according to the measurement principle, the film thickness measurement system can be divided into a laser film thickness measurement system, an X-ray film thickness measurement system, an ultrasonic film thickness measurement system, and the like. [0003] Such as figure 1 as shown, figure 1 A mainstream film thickness measurement system 100 in the prior art is sho...

AI Technical Summary

Problems solved by technology

[0004] Therefore, since the film thickness measurement system in the prior art adopts the independently set PLC control part as the control master station, when controlling the movement of the mechanical arm according to the judgment result of the upper computer, the data transmission path is complicated and the data transmission time is long. It may cause the measurement time of the film thickness measurement system to be long, and the system responds slowly when the film thickness measurement is abnormal, which cannot meet the high productivity demand of measuring the film thickness of the workpiece to be measured
