Problems solved by technology
[0002] The on-line detection of steel plate surface film thickness is mainly used in the quality control of steel products. In the past, the quality inspection was completed in three steps: sampling, laboratory contact detection, and adjustment of the production process according to the laboratory feedback results, that is, the off-line method. This method reflects the problem Lag, and consume manpower and material resources, seriously reduce the efficiency of quality inspection, affect the timely adjustment of production technology, thereby reducing product quality and increasing production costs

The invention discloses a control system for steel plate surface film thickness online detection. Upper and lower guide rails of the system are respectively arranged on the top and bottom of a frame-shaped rack. The tail ends of upper and lower slide rods are respectively arranged on the upper and lower guide rails through servo motors, and the upper and lower slide rods move along the upper and lower guide rails under the drive of the servo motors. Upper and lower probes are respectively arranged at the front ends of the upper and lower slide rods. Limit switches are respectively arranged atthe two ends of the upper and lower guide rails. Photoelectric sensors are respectively arranged on the two sides of the upper and lower probes. The upper and lower probes are electrically connected with a data switch. A servo controller is electrically connected with the upper and lower servo motors and a PLC. The limit switches and the photoelectric sensors are electrically connected with the PLC. The data switch is electrically connected with a display terminal and the PLC. With the system, the thickness of the film on the surface of a steel plate can be detected online and in real time, the defects of the traditional sampling detection are avoided, the efficiency of quality inspection is improved, the input of human and material resources is reduced, the rate of qualified products is greatly improved, and the production cost is reduced.
