Example Embodiment

[0030] As mentioned in the background art, the mainstream film thickness measurement system in the prior art has technical problems of long measurement time and slow system response.

[0031] The inventor of this application figure 1 The film thickness measurement system 100 shown was further analyzed. Continue to refer figure 1 , The laser pulse generated by the laser measuring head 10 heats the paint layer of the workpiece 102 under test (here, the workpiece 102 to be tested is an automobile subjected to electrophoresis painting treatment as an example, and through the paint layer The electrophoretic immersion paint layer (KATAPHORESE TAUCH LACKIERUNG, KTL for short) reflects attenuated heat waves, which are transformed by the sensing unit (not shown) in the ECU101 into the film thickness of the measuring point on the workpiece The electrical signal is used by the data acquisition unit 20 for data collection, and the collection result is transmitted to the upper computer 30 for...

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...
