[0035] Working principle: by driving the motor 1 402 to drive the rotating shaft 403, the rotating shaft 403 drives the transmission belt 404, and then drives the PCB tray 9 to be located at the top of the transmission device 4 to move, and by setting the lifting component 8 on the inner wall of the transmission device 4, when the PCB tray 9 moves to the top of the lifting component 8 through the transmission belt 404, the lifting component 8 can directly rise to drive the PCB tray 9, so that the PCB tray 9 passes through the detection component 7 for detection; Specifically, by fixing the top telescopic end of the telescopic cylinder 4 802 and the top of the slide plate 3 803, the telescopic cylinder 4 802 can drive the slide plate 3 803 to move up and down; The mobile platform 8044 is driven to move by the telescopic rod 8043, so that the telescopic cylinder 802 drives the bracket component 804 to rise through the slide plate 803, so that the PCB tray 9 is supported by the bracket component 804, and the telescopic rod 8043 on one side is used to drive the mobile platform 8044 to move, so that the mobile platform 8044 drives the PCB tray 9 to be located at the top of the frame 8041 to move. When it moves to a suitable position, the telescopic rods 8043 on both sides drive the mobile platform 8044 to contract, so that the mobile platform 8044 drives the turntable 8046 to fit and clamp the PCB tray 9 through the frosted ring 8047, and at the same time, the turntable 8046 is driven to rotate by the driving motor 8045, and the frosted ring 8047 fits with the outer wall of the PCB tray 9, so that the PCB tray 9 moves along the rotation direction of the frosted ring 8047, so that the PCB tray 9 moves to the detection position of the detection camera 713; The PCB board 904 is limited by the limiting plate 902 so that the PCB board 904 does not move, and when the PCB tray 9 is located on the top of the lifting component 8, the magnet 903 can be used to achieve positioning; The second telescopic rod 8043 on one side is used to drive the moving platform 8044 to move, so that the moving platform 8044 drives the PCB tray 9 to move on the top of the frame 8041, and at the same time, the turntable 8046 is driven by the third driving motor 8045 to rotate, and the frosted ring 8047 and the outer wall of the PCB tray 9 are fitted together, so that the PCB tray 9 can move along the rotation direction of the frosted ring 8047. When the PCB tray 9 moves to the detection position of the detection camera 713, the operation of the electromagnet 8042 is controlled to make the electromagnet 8042 and the magnet 903 adsorb each other, so that the PCB tray 9 is fixed by the lifting component 8; Then, the device directly places the PCB tray 9 at the detection position of the detection camera 713, thereby avoiding the problem that the PCB board 904 needs to be taken out of the PCB tray 9 for manual detection, and then placed in a fixed position of the detection device. After the detection is completed, the PCB board 904 is placed in the PCB tray 9. In this detection process, the process of placing the PCB board 904 back and forth is too cumbersome. The lead screw 503 is driven by a driving motor, and the sliding frame 504 is limited by the sliding rod 502, so that the sliding frame 504 can move along the sliding rod 502, and the telescopic end of the telescopic cylinder 505 is fixedly assembled with the mounting frame 506, and the telescopic cylinder 505 and the mounting frame 506 are slidably connected, so that the telescopic cylinder 505 drives the mounting frame 506 to move up and down, and the two groups of telescopic cylinders 507 drive the clamping plate 508 to be extended and retracted, so that the two groups of telescopic cylinders 507 and the clamping plate 508 can clamp the PCB tray 9; Through the coordinated use of the above structure, the selection component 5 can clamp the PCB tray 9 on the top of the transmission device 4 and make the PCB tray 9 separate from the transmission device 4, so that when the detection component 7 detects an unqualified PCB tray 9, the unqualified PCB tray 9 can be taken out by the selection component 5; By fixing the telescopic end of telescopic rod 1 603 and slide plate 1 602, and slidingly sleeved slide plate 1 602 and mounting plate 601, telescopic rod 1 603 can drive slide plate 1 602 to move up and down during operation, and by fixing the telescopic end of telescopic cylinder 3 605 and slide plate 2 606, and slidingly sleeved slide plate 2 606 and telescopic cylinder 3 605, telescopic cylinder 3 605 can drive slide plate 1 602 to move left and right during operation, so that the auxiliary clamping assembly 6 can clamp the PCB tray 9 on the top of the transmission device 4 through the electric clamp 607, and the auxiliary clamping assembly 6 assists the selecting assembly 5 to clamp and fix the PCB tray 9.
