The metal plate paste thickness detection device provided by the embodiment is used for detecting the thickness of the non-transparent paste material coated on the surface of the metal plate, and solves the defects caused by the fact that the paste needs to be dried and then measured in the prior art.
In the detection process, the small coil arranged in the eddy current sensor probe can generate an oscillating electromagnetic field under the control of the controller, when the eddy current sensor probe approaches to the metal plate with paste coated on the surface, induced current is generated on the surface of the metal plate, a reverse electromagnetic field is generated, and at the moment, the eddy current sensor can obtain the distance X between the eddy current sensor probe and the surface of the metal plate according to the strength of the reverse electromagnetic field. The semiconductor laser emission beam of the laser sensor irradiates the paste surface to form diffuse reflection of light, and the reflected light is received by the photosensitive element through the lens, so that the distance Y between the semiconductor laser emission beam and the paste surface is obtained. Therefore, the thickness of the paste can be obtained according to the measurement result in the follow-up process, and the purpose of measurement is achieved.
In another embodiment of the present invention, a system for detecting thickness of a metal sheet paste, as shown in fig. 1, comprises: a horizontal support table 20; a roller 13 arranged below the horizontal support table 20; a support structure 30 fixed above the horizontal support table, on which a slide rail 40 is arranged in the width direction of the metal plate; at least one metal plate paste thickness detection device 10 which is arranged on a sliding rail of the supporting structure and can slide along a preset area in the direction of the sliding rail; the industrial personal computer is connected with the metal plate paste thickness detection device and is used for calculating paste thickness according to the measured result of the metal plate paste thickness detection device.
In this embodiment, dispose the metal sheet rubberizing thickness detection device on bearing structure's slide rail, like this, metal sheet rubberizing thickness detection device just can remove along the slide rail to the thickness of below metal sheet surface lotion carries out real-time detection to feed back the detection result to the industrial computer in real time, realize the real-time monitoring to wet film. Here, after the metal sheet marches the horizontal support platform surface, control metal sheet scribbles cream thickness detection device and begins to remove along the slide rail, and the slide rail sets up along the width direction of metal sheet, like this, at the in-process that the metal sheet goes on, metal sheet scribbles cream thickness detection device and reciprocates along the slide rail in step, realizes detecting the special orbit on the metal sheet surface lotion, like oblique Z font lotion thickness, realizes detecting a plurality of different bit paste thickness on the metal sheet surface, improves detection precision.
