[0021] Reference Figure 1 and Figure 5As shown, a third mounting block 5 is fixedly connected to the upper end of the base 1 and the front of the first mounting block 3.

The output end of the third motor 57 extends into the interior of the third sliding groove 55 and is fixed to the left end of the third threaded rod 56. A fixed connection is made, and a movable plate 58 is threadedly connected to the outer surface of the third threaded rod 56.

Based on the image captured by the industrial camera body 47 and the analysis of the control device 2, the distance to the measuring plate 511 can be measured in real time by the laser sensor 54, thereby causing the movable block 510 to abut against the left end of the PCB board.

[0022] The working principle and usage process of this utility model are as follows: In use, the PCB board to be inspected is placed on the upper end of the placement block 51, with the right end of the PCB board abutting against the left end of the positioning block 52. Then, the control device 2 controls the first electric telescopic rod 45 to adjust the distance between the industrial camera body 47 and the PCB board. When the industrial camera body 47 moves to the appropriate position, it captures an image of the PCB board. The image data is then transmitted to the control device 2. The control device 2 analyzes the captured image using an image processing algorithm to identify specific positioning marks or component features on the PCB board. After the image is captured, the first electric telescopic rod 45 moves the industrial camera body 47 upwards to the appropriate position. Then, the control device 2 controls the third motor 5... 7 drives the third threaded rod 56 to rotate, thereby enabling the movable block 510 to move closer to the other end of the PCB board via the moving plate 58. Through the cooperation of the photoelectric sensor and the ranging plate 511, the right end of the movable block 510 abuts against the other end of the PCB board, thereby limiting and fixing the PCB board. Then, the control device 2 starts the first motor 33, the second motor 43 and the second electric telescopic rod 48. The first motor 33 drives the detection device 410 to move left and right, the second motor 43 drives the detection device 410 to move back and forth, and the second electric telescopic rod 48 drives the detection device 410 to move up and down, thereby adjusting the detection device 410 to the accurate detection position. At this time, the PCB board can be detected.
