The movable ends of the two first electric push rods 6 are fixedly connected with a positioning block 10, the movable ends of the two second electric push rods 7 are fixedly connected with a dial plate 11, the outer wall of the fixing frame 9 is fixedly connected with a return spring 12, one end of the return spring 12 is fixedly connected with a movable block 13, and the inner walls of the fixing seat 1 are respectively installed with a first conveying device 14 and a second conveying device 15. The first electric push rod 6 drives the positioning block 10 to slide, so that the PCB board can be positioned to one end of the fixing frame 9 for loading, and when the test is completed, the elasticity of the return spring 12 drives the PCB board to pop out quickly for unloading, thereby improving the convenience of loading and unloading operations and solving the time-consuming and labor-intensive problems caused by complicated operations.

[0026] Furthermore, the bracket 9 has a Z-shaped structure when viewed from the side, with its lower end positioned below the detection module 4, facilitating support for PCB positioning. One end of the bracket 9 has an inclined cross-section, and the bottom of the bracket 9 is aligned with the bottom of the positioning block 10. The bottom of the positioning block 10 also has an inclined cross-section, and the bottom of the positioning block 10 cooperates with one end of the bracket 9, facilitating the positioning of the PCB after the positioning block 10 slides.

[0027] The paddle 11 forms a telescopic structure with the fixing frame 9 via a return spring 12.

After the test is completed, the first electric push rod 6 drives the positioning block 10 to reset and slide, so that the reset spring 12 is reset and deformed, and then the PCB board is ejected through the movable block 13 and falls back onto the first conveying device 14. At the same time, the control module 8 controls the second electric push rod 7 to start, so that the second electric push rod 7 drives the paddle 11 to slide, so that the paddle 11 drives the unqualified PCB board to move to the second conveying device 15 for conveying, and the qualified PCB board needs to be conveyed by the first conveying device 14.

[0031] In summary, with the help of the above technical solution of the present invention, through automated control, the convenience of overall operation is improved, and different PCB board products are driven to be classified and unloaded, further saving manpower operations.
