When in use, the PLC control system controls the Y-direction motor 430 to work, and the Y-direction motor 430 drives the adapter 440 connected to the Y-direction guide rail 420 to move, and then drives the 3D camera 450 fixed on the adapter 440 to move, so that the 3D camera 450 works above the inspection table 100.

[0041] The inspection tool 400 also includes a light source assembly 460 disposed in the sealed detection chamber 1a of the frame 1 and below the 3D camera 450. The height of the light source assembly 460 is lower than the height of the detection platform 100 and does not affect the use of the detection platform. The light source assembly 460 uses an LED light source. Since the sealed detection chamber 1a is a sealed space, the light source assembly 460 illuminates the tobacco to be detected placed on the detection platform 100 without being affected by external light sources, thereby improving the imaging effect.

[0042] The cleaning tool 500 is arranged in the sealed detection chamber 1a of the frame 1 and is used to sweep away the tobacco shreds after the shooting is completed. The cleaning tool 500 in this embodiment includes a brush arranged in the sealed detection chamber 1a of the frame 1 and located above the detection table 100 and used to sweep away the tobacco shreds on the detection table 100, and a swing motor arranged in the sealed detection chamber 1a of the frame 1 and controlling the back and forth movement of the brush. When in use, after the 3D camera 450 has finished shooting, the PLC control system transfers the detection table 100 to the next station, and sweeps away the tobacco shreds on the detection table 100 through the cleaning tool 500 and discharges them from the discharge port 120.

[0043] In order to enable the detection platform to move, a moving mechanism 600 for sliding the detection platform 100 is provided in the sealed detection chamber 1a of the frame 1, and the moving mechanism 600 includes an X-direction guide rail 610 provided on the frame 1, a slider 620 provided on the X-direction guide rail 610 and connected to the detection platform 100, and an X-direction motor 630 provided on the frame 1 and used to drive the detection platform 100 to move on the X-direction guide rail 620. Specifically, the X-direction motor 630 adopts a servo motor.

[0044] The working principle of the utility model is as follows:

[0045] First, the tobacco shreds dropped from the vibrator 1000 enter through the receiving port 110, and the tobacco shreds to be tested fall from the receiving port 110 into the testing platform 100 below, and then the PLC control system controls the X-axis motor 630 to work and drive the testing platform 100 to move. When the testing platform 100 moves to the flattening fixture 200, the Z-axis motor 230 is controlled by the PLC control system to work, and the Z-axis motor 230 works to make the pressing plate 240 connected to the Z guide rail 220 move downward to flatten the tobacco shreds to be tested, and then the PLC control system controls the X-axis motor 630 to work and drive the testing platform 100 to move. When the testing platform 100 moves to the pre-inspection fixture 300, when the positioning camera 320 captures that the tobacco shreds to be tested are unevenly flattened or piled, the PLC control system directly sends the tobacco shreds to be tested on the testing platform 100 to the discharge port 120 for discharge. Otherwise, the next process is carried out, and then The PLC control system controls the X-axis motor 630 to move the inspection platform 100. When the inspection platform 100 moves to the inspection tool 400, since the sealed inspection chamber 1a is a sealed space, the tobacco to be inspected placed on the inspection platform 100 is irradiated by the light source assembly 460, which is not affected by external light sources, thereby improving the imaging effect. Subsequently, the PLC control system controls the Y-axis motor 430 to work, and the Y-axis motor 430 drives the adapter 440 connected to the Y-axis guide rail 420 to move, thereby driving the 3D camera 450 fixed on the adapter 440 to move, so that the 3D camera 450 works above the inspection platform 100. Subsequently, the PLC control system controls the X-axis motor 630 to move the inspection platform 100. When the inspection platform 100 moves to the cleaning tool 500, the tobacco on the inspection platform 100 is swept away by the cleaning tool 500 and discharged from the discharge port 120.
