[0022] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions: a PCB circuit board detection device, comprising: a bottom plate 1, a lower conveying roller 2 is installed on the upper end surface of the bottom plate 1, an upper conveying roller 3 is installed above the lower conveying roller 2, a first support plate 4 and a second support plate 5 are installed on both sides of the upper end surface of the bottom plate 1, a lower light source lamp 6 is installed on the upper end surface of the bottom plate 1, a mounting plate 7 is provided between the first support plate 4 and the second support plate 5 on both sides, a rotating assembly is provided between the mounting plates 7 on both sides and the first support plate 4, an upper light source lamp 11 installed upside down is provided on the mounting plates 7 on both sides, and a telescopic assembly is provided between the upper light source lamp 11 on both sides and the mounting plates 7;

[0023] A camera assembly is provided above the bottom plate 1 .

[0024] Furthermore, the telescopic assembly includes a fixed plate 8, an electric telescopic rod 9 and a connecting plate 10. The fixed plate 8 is connected to one side of the upper end surface of the mounting plate 7. The electric telescopic rod 9 is horizontally installed on the fixed plate 8. The connecting plate 10 is installed on the output end of the electric telescopic rod 9, and the connecting plate 10 is connected to the upper light source lamp 11.

[0025] Furthermore, the camera assembly includes a carrier plate 18 and an industrial camera 19 . The carrier plate 18 is mounted on the top of the first support plate 4 and the second support plate 5 , and the industrial camera 19 is mounted on the lower end surface of the carrier plate 18 .

[0026] Through the above technical solution:

[0027] When in use, the PCB circuit board is placed between the lower conveyor roller 2 and the upper conveyor roller 3, and the PCB circuit board is conveyed. After being conveyed to the appropriate position, it is photographed for inspection through the industrial camera 19. The industrial camera 19 is used to capture high-resolution images of the PCB circuit board. These images are crucial for subsequent analysis and inspection because they provide visual information of all details on the circuit board. When inspecting a light-transmitting PCB circuit board, the lower light source lamp 6 is turned on, and the upper electric telescopic rod 9 is started. The electric telescopic rod 9 drives the upper light source lamp 11 to retract to the top of the mounting plate 7 through the connecting plate 10, so that the lower light source lamp 6 and the upper light source lamp 11 are staggered to avoid interference between the lower light source lamp 6 and the upper light source lamp 11. The retracted upper light source lamp 11 does not block the working range of the industrial camera 19, which helps to quickly and accurately identify The defects on the PCB circuit board can be identified, thereby improving the overall detection efficiency, and the retracted upper light source lamp 11 can avoid the light source from being exposed, so that dust, moisture or other environmental factors will not damage the light source, thereby extending the service life of the light source; when detecting non-transparent PCB circuit boards, the lower light source lamp 6 is not lit, and the electric telescopic rod 9 drives the upper light source lamp 11 to emerge from the mounting plate 7 through the connecting plate 10. According to needs, the area where the upper light source lamps 11 on both sides emerge is controlled to ensure that only the area that needs to be detected is illuminated, thereby improving the accuracy and efficiency of detection, and limiting the irradiation area of ​​the light source can reduce unnecessary light pollution, and avoid interference with the surrounding environment or operators. By setting the lower light source lamp 6 and the upper light source lamp 11, it is possible to detect both translucent PCB circuit boards and non-translucent PCB circuit boards.

[0028] See also Figure 1-Figure 3 As shown, the rotating assembly includes a rotating motor 15, a rotating shaft 16 and a bearing 17. The rotating motor 15 is mounted on the side wall of the first support plate 4, the rotating shaft 16 is connected to the output end of the rotating motor 15, the bearing 17 is mounted on the side wall of the second support plate 5, and the rotating shaft 16 and the bearing 17 are connected, and the mounting plate 7 is connected to the outer wall of the rotating shaft 16.

[0029] Through the above technical solution:

[0030] When in use, start the rotating motor 15, and the rotating motor 15 drives the mounting plate 7 to rotate through the rotating shaft 16. The rotating mounting plate 7 can adjust the irradiation direction of the upper light source lamp 11. By adjusting the angle of the light source, the irradiation direction and intensity of the light can be better controlled, shadows and reflections can be reduced, and the quality and contrast of the detection image can be improved. Correctly adjusting the angle of the light source can reduce glare to the operator and reflection on the surface of the PCB circuit board, thereby improving the comfort and safety of the operating environment. The upper light source with adjustable direction can provide customized lighting for different detection needs and specific areas of the PCB circuit board, thereby improving the flexibility and adaptability of detection.

[0031] For further information, see Figure 1-Figure 4 As shown, strip plates 12 are installed on both sides of the upper end surface of the mounting plate 7, and multiple rolling assemblies are installed on the strip plates 12 on both sides.

[0032] Furthermore, the rolling assembly includes a rolling groove 13 and a ball 14 . The rolling groove 13 is opened on the upper end surface of the strip plate 12 . The ball 14 is installed in the rolling groove 13 , and the ball 14 can contact the upper light source lamp 11 .

[0033] Specifically, when the mounting plate 7 moves, it drives the ball 14 to roll in the rolling groove 13, thereby converting the sliding friction between the mounting plate 7 and the strip plate 12 into rolling friction, reducing the friction force. Due to the reduction in friction force, the movement of the moving parts is smoother, reducing the resistance during startup and operation, and improving the overall mechanical efficiency.
