[0023] like Figure 3 and Figure 4As shown, the adjustment assembly includes a support frame 14, a second motor 15, a first lead screw 16, a moving frame 17, a third motor 18, a second lead screw 19, and a moving block 20. The support frame 14 is connected to the inner side of the upper right part of the outer casing 2. The second motor 15 is connected to the rear of the support frame 14. The second motor 15 and the processor are electrically connected through a control module. The first lead screw 16 is connected to the output shaft of the second motor 15.

The second lead screw 19 is rotatably connected to the moving frame 17. The moving block 20 is threadedly connected to the second lead screw 19. The moving block 20 is slidably connected to the moving frame 17.

[0024] like Figure 4 and Figure 5 As shown, the detection assembly includes a second electric telescopic rod 21, a connecting block 22, a fourth motor 23, a rotating block 24, a probe 25, and a spring 26. The second electric telescopic rod 21 is connected to the lower side of the moving block 20. The second electric telescopic rod 21 and the processor are electrically connected through a control module. The connecting block 22 is connected to the telescopic end of the second electric telescopic rod 21. The fourth motor 23 is connected to the inner side of the connecting block 22.

A spring 26 is connected between the rear probe 25 and the rotating block 24.

[0025] When it is necessary to detect poor solder joints in electronic components, this device can be used. The support leg 1 is brought into contact with the ground, then the rotating door 4 is opened to disengage from the magnet 3, bringing the door 4 into contact with the ground. Next, the folding frame 5 is pulled down and pulled out, then rotated to unfold the first conveyor belt 6. The electronic component is then placed on the first conveyor belt 6, which transports the component. The limiting rod 7 limits and guides the component, moving it to the second conveyor belt 10. The second conveyor belt 10 continues to transport the component until it reaches the center of the rotating platform 9. The processor then activates the first electric telescopic rod 11 via the control module, which moves the push plate 12, thus centering the electronic component. The first motor 8 and lamp 201 are then activated for illumination. The first motor 8 drives the rotating platform 9 to rotate, causing the electronic component to rotate. The vision sensor 13 performs a comprehensive inspection of the electronic component's shape, detecting issues such as poor solder joints, misalignment, and bridging. After inspection, the first motor 8 is turned off.

[0026] Based on the positions of the pins and pads on the electronic components, the second motor 15 is activated, which drives the first lead screw 16 to rotate. Under the action of the screw, the moving frame 17 moves along the support frame 14, thereby adjusting the position of the probe 25 in the front-to-back direction. After adjustment, the fourth motor 23 is activated, which drives the rotating block 24 to rotate, causing the probe 25 to rotate for further position adjustment. After adjustment, the second electric telescopic rod 21 is activated, which drives the connecting block 22 to move, causing the rotating block 24 to move, and thus the probe 25 to move. The probe 25 is pressed and moved when it contacts the pin and the pad respectively, compressing the spring 26. Then, the third motor 18 is activated, which drives the second lead screw 19 to rotate. Under the action of the thread, the moving block 20 moves, which in turn moves the probe 25 left and right. The probe 25 is then energized to detect cold solder joints in the electronic component. If there is continuity, the soldering is reliable. If there is no continuity, it indicates that there are problems such as missing solder, cold solder joint, open circuit, short circuit, or misalignment of the pin. Alternatively, the third motor 18 can be activated first to adjust the position of the probe 25 left and right, and then the second motor 15 can be activated. The probe 25 moves back and forth for detection. After the detection is completed, the second electric telescopic rod 21 operates in the opposite direction, causing the connecting block 22 and the rotating block 24 to move and reset, driving the probe 25 to move and reset and disengage from the electronic component. The spring 26 rebounds, and the probe 25 moves and resets. Then, the first motor 8 operates, driving the rotary table 9 to rotate, causing the second conveyor belt 10 to rotate towards the discharge port, thereby driving the push plate 12 and the electronic component to rotate. Then, the first electric telescopic rod 11 operates in the opposite direction, causing the push plate 12 to move and reset and disengage from the electronic component. Then, the second conveyor belt 10 operates in the opposite direction to transport the electronic component, causing the electronic component to be discharged from the discharge port for collection. Then, the first motor 8 operates, causing the rotary table 9 and the second conveyor belt 10 to rotate and reset. Then, the first conveyor belt 6 continues to transport the electronic component onto the second conveyor belt 10. The above operation is repeated to center, detect, and discharge the electronic component until the detection is completed. This allows for the simultaneous transport and centering of the electronic component and adjustment of the probe 25 position to detect poor soldering of the electronic component. This facilitates all-round detection, adapts to the detection of electronic components of different specifications, and improves detection accuracy and efficiency.

[0027] After use, the probe 25 is moved to the far right by the cooperation of the third motor 18 and the second lead screw 19. Then, the light 201, the first conveyor belt 6, the first motor 8, the second conveyor belt 10, the first electric telescopic rod 11, the vision sensor 13, the second motor 15, the third motor 18, the second electric telescopic rod 21, and the fourth motor 23 are turned off. Then, the folding frame 5 is rotated to fold up, and then the folding frame 5 is moved upward and pushed to move back to its original position. Then, the door 4 is turned to close, and the door 4 is attracted and fixed by the magnet 3. This allows the folding frame 5 to be unfolded for the transport and use of electronic components while being conveniently folded up for protection, reducing space, facilitating transportation and storage, preventing damage, extending service life, and reducing costs. Then, the device can be removed.
