[0040] Working principle: When conducting a test, first place the object to be tested on the upper surface of the transmission belt 4, then start the driving shaft 2, and the driving shaft 2 rotates. After the driving shaft 2 rotates, it can drive the transmission belt 4 to transmit, so that the object on the transmission belt 4 can be transmitted to the inside of the upper cover 11. When the driving shaft 2 rotates, it can also drive the driven shaft 3 to rotate. After the driven shaft 3 rotates, it can drive the eccentric wheel 607 to rotate. After the eccentric wheel 607 rotates, it can drive one end of the driving rod 606 to move back and forth, thereby driving the push-pull rod 603 to move back and forth. After the push-pull rod 603 moves back and forth It can drive the piston plate 602 to move back and forth. When the piston plate 602 moves toward one end of the eccentric wheel 607, the second one-way valve 605 is closed and the first one-way valve 604 is opened, so that the suction force can be transmitted to the air distribution pipe 609 through the exhaust pipe 608. At this time, the air in the dust box 805 and the storage shell 708 can be sucked away. When the piston plate 602 moves to the side away from the eccentric wheel 607, the first one-way valve 604 is closed and the second one-way valve 605 is opened, so that the air in the air cylinder 601 can be squeezed into the interior of the inflation pipe 702, thereby squeezing the gas into the interior of the charging tank 701. When the air pressure inside the charging tank 701 is sufficient, the body fluid fluorescent agent can be pressed into the interior of the connecting tube 703 by relying on the high pressure of the charging tank 701, and squeezed into the interior of the mounting tube 704 through the connecting tube 703, and the liquid can be atomized and sprayed out through the liquid spray head 705, so that it can be sprayed on the object to be detected. At this time, the suction force is transmitted to the storage shell 708 through the air distribution pipe 609, and is sucked away by the air in the storage shell 708. Therefore, an air pressure difference is generated inside the storage shell 708, and suction can be generated. The suction force is transmitted to the mist suction head 706 through the mist suction pipe 707. At this time, the mist suction head 706 is used to remove the scattered The atomized liquid inside the upper cover 11 is drawn into the interior of the storage shell 708. When the mist absorbing sponge 711 is full of liquid, the handle 713 is pulled outward, thereby driving the anti-blocking mounting plate 712 to move outward. After the anti-blocking mounting plate 712 is pulled outward, the mist absorbing sponge 711 can be driven to move outward. At this time, the extrusion ramp block 709 can be used to squeeze the liquid on the mist absorbing sponge 711 and scrape it into the interior of the storage shell 708. When the mist absorbing sponge 711 is completely moved out of the interior of the storage shell 708, the liquid scraped into the interior of the storage shell 708 can be poured out, thereby preventing the fluorescent liquid from being wasted.

[0041] When the driving shaft 2 rotates, the driven shaft 3 can be driven to rotate through the transmission belt 4. After the driven shaft 3 rotates, the roller brush 802 can be driven to rotate through the belt. After the roller brush 802 rotates, the object to be detected can be cleaned, and at the same time, the air distribution pipe 609 can extract the air inside the dust box 805, and transmit the suction force to the inside of the dust head 803 through the connecting hose 804. At this time, the dust cleaned by the roller brush 802 is absorbed into the inside of the dust box 805 by the dust head 803. When the detection is finished, the threaded sealing cover 807 can be unscrewed, and the dust inside the dust box 805 can be removed through the material taking pipe 806, so that the workpiece can be cleaned before detection, thereby improving the detection effect, reducing the workload of the staff, and improving the detection efficiency. At this time, the object to be detected can be detected by the detection camera 13;

[0042] When the workpiece is large, the threaded column 902 is turned, and the threaded column 902 can drive the lifting frame 901 to move upward during rotation, thereby driving the mounting frame 801 to move upward, and then driving the roller brush 802 to move upward, so as to adapt to larger workpieces.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
