A rotating rod 26 is rotatably mounted on the block 28, and the rotating rod 26 is in sliding contact with another sliding port 3. A cleaning assembly is fixedly sleeved on the outer side of the rotating rod 26, and the cleaning assembly includes a cross mounting frame 17 fixedly sleeved on the outer side of the rotating rod 26. An opening 19 is penetrated through one side of the cross mounting frame 17, and a mounting plate 22 is slidably connected in the opening 19. A connecting spring 31 is fixedly arranged between the mounting plate 22 and the opening 19. A brush 15 is installed on the outer side of the mounting plate 22. The outer side of the mounting plate 22 is arc-shaped and made of soft rubber. During detection, the starting motor 9 can control the movement of the mounting frame 2, so that the mounting plate 22 drives the brush 15 to move, and the wood chips on the surface of the plate are cleaned in advance; A connecting piece for controlling the rotation of the rotating rod 26 is provided on one side of the detection platform 1. The connecting piece includes a rotating ring 23 fixedly sleeved on one end of the rotating rod 26. A plurality of mounting grooves 20 are provided on the outer side of the rotating ring 23. An arc-shaped tooth 25 is slidably connected in the mounting groove 20. A telescopic spring 21 is fixedly provided between the arc-shaped tooth 25 and the mounting groove 20. A sawtooth bar 10 for controlling the rotation of the rotating ring 23 is fixedly installed on one side of the detection platform 1 (the sawtooth bar 10 is composed of a long plate and a plurality of groups of saw teeth, and the plurality of groups of saw teeth are arranged on the long plate at equal intervals. Each group of saw teeth can control the rotating rod 26 to rotate a quarter of a circle).

After the detection is completed and the control installation frame 2 is reset, the sawtooth bar 10 will squeeze the arc-shaped tooth 25 to slide into the mounting groove 20, so that the rotating rod 26 does not rotate during the reset process. A limit assembly for limiting the rotation rod 26 is arranged in the slider 28, and the limit assembly includes an annular block 29 fixedly sleeved on the outside of the rotation rod 26, and a plurality of arc-shaped spring plates 27 are fixedly installed at equal intervals on the outside of the annular block 29.

During the detection process, when the motor 9 works to control the movement of the mounting frame 2, the rotation rod 26 can be limited by the cooperation of the arc-shaped protrusions 24 and the arc-shaped spring plates 27, so that each time the rotation rod 26 rotates to switch the bristles 15, it can be ensured that the bristles 15 are in contact with the surface of the plate for cleaning. The cleaning assembly for cleaning the cleaning assembly is installed on one side of the slider 28, and a rotating member for controlling the extension and retraction of the cleaning assembly is fixedly installed on the slider 28. The cleaning assembly includes a fixed cylinder 16 fixedly installed on one side of the slider 28, and a connecting port 33 is opened on one side of the fixed cylinder 16. The mounting plate 22 is abutted against the connecting port 33. The thickness of the mounting plate 22 is greater than the height of the connecting port 33, and the length of the mounting plate 22 is greater than the width of the connecting port 33. A rotating shaft 8 is rotatably installed in the fixed cylinder 16, and a plurality of rotating frames 32 are fixedly installed on the outer side of the rotating shaft 8. One end of the rotating shaft 8 passes through one of the sliding ports 3 and is fixedly sleeved with a gear ring 5. A serrated plate 6 meshing with the gear ring 5 is fixedly installed on one side of the detection table 1. During the detection process, when the motor 9 works to control the movement of the mounting frame 2, the cooperation between the gear ring 5 and the serrated plate 6 can make the rotating shaft 8 drive the rotating frame 32 to rotate, so as to beat and clean the bristles 15 that have just been cleaned, so as to avoid wood chips mixed in the bristles 15 and affect the cleaning effect next time.

[0021] As a further technical solution of the present invention, the rotating part includes a disc 14 fixedly connected to a slider 28, an annular groove is provided on one side of the disc 14, and the annular groove is composed of a first arc groove 13, a second arc groove 12 and a horizontal groove 11 which are interconnected. One end of the mounting plate 22 is fixedly connected to a sliding rod 18 which is slidably connected to the annular groove. In the process of controlling the rotation of the rotating rod 26, the bristles 15 that have just been cleaned can be controlled to move to the fixed cylinder 16 through the cooperation of the annular groove and the connecting spring 31 to clean the bristles 15.

[0022] As a further technical solution of the present invention, the fixed cylinder 16 is composed of two arc-shaped shells, one of which is fixedly connected to the slider 28, and rotating blocks 34 are fixedly installed on the two arc-shaped shells. The two rotating blocks 34 are rotatably connected by a spring shaft. This rotating structure is a prior art and will not be described in detail here. In the presence of external force, the fixed cylinder 16 can be rotated to open the fixed cylinder 16 to clean the wood chips inside. In the absence of external force, the fixed cylinder 16 is in a closed state.

[0023] Working principle: During random inspection, the board to be inspected is placed on the inspection table 1, the motor 9 is started to drive the threaded rod 7 to rotate, the threaded rod 7 drives the installation frame 2 to move, the installation frame 2 drives the slider 28 to slide in the sliding opening 3, and the slider 28 drives the rotating rod 26, the fixed cylinder 16 and the disc 14 to move when moving; The rotating rod 26 drives the cross mounting frame 17 to move when it moves, and the cross mounting frame 17 drives the brush 15 to move through the mounting plate 22, so as to clean the wood chips on the surface of the board in advance, and then the detection probe 4 can detect the cleaned board; When the rotating rod 26 is moving and the extruded arc-shaped teeth 25 are not in contact with the sawtooth bar 10, the rotating rod 26 can be limited by the cooperation of the arc-shaped protrusion 24 and the arc-shaped spring plate 27, so that each time the rotating rod 26 rotates and switches the bristles 15, it can be ensured that the bristles 15 are in contact with the surface of the plate for cleaning. When the rotating rod 26 is moving, the arc-shaped teeth 25 are squeezed to contact the sawtooth bar 10, so that the rotating rod 26 can rotate a quarter of a circle to switch the bristles 15, so as to avoid using one set of bristles 15 all the time, which affects the cleaning effect. After the detection is completed, the motor 9 is started to reverse and control the installation frame 2 to reset. During this process, the sawtooth bar 10 squeezes the arc-shaped teeth 25 to slide into the installation groove 20, so that the rotating rod 26 does not rotate during the reset process. When the rotating rod 26 drives the cross mounting frame 17 to rotate, the cross mounting frame 17 drives the slide bar 18 to slide in the annular groove through the mounting plate 22. The bristles 15 that have just finished cleaning slide from the first arc groove 13 through the second arc groove 12 to the horizontal groove 11, and then the slide bar 18 is pushed to slide in the horizontal groove 11 by the action of the connecting spring 31 until it slides to the connection between the horizontal groove 11 and the first arc groove 13. At this time, the bristles 15 that have finished cleaning are pushed into the fixed cylinder 16, and the mounting plate 22 on one side of the bristles 15 abuts against the connecting port 33. The fixed cylinder 16 drives the rotating shaft 8 to move during the movement. Through the cooperation of the gear ring 5 and the serrated plate 6, the rotating shaft 8 can drive the rotating frame 32 to rotate, and the bristles 15 that have just been cleaned are patted and cleaned to avoid wood chips mixed in the bristles 15, which will affect the cleaning effect next time.
