[0031] The detection table 200 is provided with a detection component for detecting the thickness of the steel plate, and the detection component includes a thickness monitoring component and a marking component. The thickness monitoring component is arranged on the left side of the inner wall of the detection table 200, and the thickness monitoring component includes a detector housing 300. The detector housing 300 is provided with a detection component. The bottom end of the outer wall of the detector housing 300 is provided with an upper detection roller 230, and the front and rear sides of the outer wall of the upper detection roller 230 are installed with a mounting frame 231. The upper detection roller 230 can be rotated at the top end of the steel plate, so as to cooperate with the bottom support roller 210 to clamp the upper and lower ends of the outer wall of the steel plate. When the thickness of the steel plate changes, the top end of the steel plate will cause the upper detection roller 230 to rotate. The position of the upper detection roller 230 is changed. When the thickness variation of the upper detection roller 230 is greater than the specified size, the marking component will be triggered to mark. A hydraulic rod device 220 is fixed at the center of the top of the outer wall of the detection platform 200 and at the position corresponding to the detector housing 300. The output end of the hydraulic rod device 220 passes through the top of the outer wall of the detection platform 200 and is fixed to the top of the outer wall of the detector housing 300. The hydraulic rod device 220 is set to adjust the position height of the upper detection roller 230 so that the upper detection roller 230 can cooperate with the detector housing 300 to detect the thickness of the steel plate. The detection component is a central slider a310. The two ends of the outer wall of the central slider a310 are connected to the detection The inner wall of the detector housing 300 is slidably connected on both sides, and the top of the mounting frame 231 is fixed to the bottom end of the outer wall of the central slider a310 through a short rod.

At the same time, the distance between the sprayer 410 and the upper detection roller 230 can be the same as the time required for the sprayer 410 to spray the fluorescent agent on the steel plate multiplied by the speed at which the steel plate is transported.

[0033] The use process of the utility model is as follows: first, personnel can convey the steel plate to the inside of the inspection table 200 and above the bottom support roller 210 through the conveying equipment, and then the hydraulic rod device 220 will drive the detector housing 300 and the upper inspection roller 230 to move downward, so that the bottom end of the upper inspection roller 230 abuts against the top of the outer wall of the steel plate, and then adjust the height of the upper inspection roller 230 so that the distance between the pressure trigger block 330 and the micro-pressure sensor 331 is the same as the positive and negative difference of the steel plate (a distance meter can be set at the output end of the hydraulic rod device 220 to measure the output length of the hydraulic rod device 220), and then personnel can start the steel plate conveying device to convey the steel plate, and the upper inspection roller 230 and the bottom support roller 210 will detect the thickness of the steel plate;

[0034] When the positive and negative values ​​of the thickness of the steel plate are greater than the specified requirements, the upper detection roller 230 will adjust the center slider a310 up and down inside the detector housing 300 through the mounting frame 231, and the center slider a310 will trigger the micro pressure sensor 331 through the pressure trigger block 330 when moving, and the micro pressure sensor 331 will transmit the data to the control end. On the one hand, the control end will send the data to the PC end of the responsible person for viewing, and on the other hand, the control end will power on the feed pump 420 and open the solenoid valve 411 at the bottom end of the sprayer 410. The feed pump 420 will absorb the fluorescent agent in the fluorescent agent storage box 400 and transport it to the sprayer 410, so that the sprayer 410 can spray on the steel plate through the bottom pipe mouth, thereby marking the steel plate.
