[0021] Among them, the two L-shaped plates 5 are respectively fixedly mounted on the upper ends of the two mounting frames 1, a guide rod 7 is fixedly connected between the parallel plate of one L-shaped plate 5 and the mounting frame 1, and a lifting screw 8 is rotatably installed between the parallel plate of the other L-shaped plate 5 and the mounting frame 1. The outer surfaces of the guide rod 7 and the lifting screw 8 are both sleeved with connecting blocks 11, one connecting block 11 is slidingly fitted with the guide rod 7, and the other connecting block 11 is connected to the lifting screw 8 by threaded cooperation. The two connecting blocks 11 are respectively fixedly connected to both sides of the lifting plate 10, and the No. 2 motor 9 is located above the lifting screw 8. The No. 2 motor 9 is fixedly mounted on the upper end of the L-shaped plate 5, and the output shaft of the No. 2 motor 9 is fixedly connected to the lifting screw 8.

[0022] When in use, start the No. 2 motor 9 to drive the lifting screw 8 to rotate. Under the restriction of the guide rod 7, the two connecting blocks 11 will move along the axial direction of the lifting screw 8, thereby controlling the height of the lifting plate 10 and the detection probe 16. When inspecting products of different sizes, the height of the detection probe 16 can be raised or lowered, thereby expanding or reducing the search range of the detection probe 16 to ensure that the detection device can be suitable for the inspection of products of different volumes.

[0023] Among them, the adjustment mechanism consists of a fixed vertical plate 12, an adjusting screw 13, a slider 14 and a No. 3 motor 15. The slider 14 is fixedly installed on the upper end of the detection probe 16. The slider 14 is slidably connected in the slide groove 19 opened on the lifting plate 10.

[0028] When in use, the No. 1 motor 4 is started to drive the transmission roller to rotate, thereby controlling the movement of the conveyor belt 2.

[0029] The utility model provides a light imaging 3D visual detection device, the specific working principle of which is as follows:

[0030] When in use, the product is placed on the conveyor belt 2, and the No. 1 motor 4 is started to drive the transmission roller to rotate, thereby controlling the conveyor belt 2 to drive the product to move. When the product moves to the bottom of the detection probe 16, the detection probe 16 will image the product light on the display screen 6, and quickly determine whether it is qualified through the control processing unit (the control processing unit is not shown in the figure). The No. 2 motor 9 is started to drive the lifting screw 8 to rotate. Under the restriction of the guide rod 7, the two connecting blocks 11 will move along the axial direction of the lifting screw 8, thereby controlling the height of the lifting plate 10 and the detection probe 16. When inspecting products of different sizes, the height of the detection probe 16 can be raised or lowered, thereby expanding or reducing the search range of the detection probe 16 to ensure that the detection device can be suitable for the inspection of products of different volumes. The No. 3 motor 15 is started to drive the adjustment screw 13 to rotate, thereby controlling the slider 14 to move along the slide groove 19, and then controlling the position of the detection probe 16 to prevent the detection probe 16 from failing to detect the edge positions on both sides of some products.
