The interior of the mobile component 107 is installed with a heat conducting plate 301 for heat conduction and heat dissipation.

[0024] During implementation, the heat dissipation fins 3033 drive the positioning clamp 3031 to the inner wall of the mobile component 107, and the user tightens the mounting studs 302 on the surface of the heat dissipation fins 3033. Under the action of the mounting studs 302, the heat dissipation fins 3033 are installed on the inner wall of the mobile component 107.

[0025] Working principle: When in use, first place the device body 1 at the specified position, and the circuit board body 109 to be inspected moves to the surface of the conveyor belt 104, and the circuit board body 109 is conveyed under the action of the conveyor belt 104. The user controls the screw body 106 by operating the display controller 102. Under the joint action of the screw body 106 and the adjusting screw, the moving component 107 is driven to slide on the surface of the frame 105, so that the moving component 107 drives the photographing component 108 to move to the required position. When the circuit board body 109 moves to the bottom of the photographing component 108, the surface of the circuit board body 109 is photographed and inspected under the action of the three cameras inside the photographing component 108, and the photographic results are displayed on the surface of the display controller 102.

[0027] Subsequently, when the cameras inside the mobile component 107 and the camera component 108 work for a long time, the temperature inside the mobile component 107 and the camera component 108 will continue to rise. At this time, the heat dissipation fins 3033 drive the positioning clamps 3031 to be clamped to the inner wall of the mobile component 107. The user tightens the mounting studs 302 on the surface of the heat dissipation fins 3033, and installs the heat dissipation fins 3033 on the inner wall of the mobile component 107 under the action of the mounting studs 302. Under the action of the heat dissipation fins 3033, the heat inside the mobile component 107 and the camera component 108 is dissipated through the heat dissipation holes 3032. Under the action of the hot plate 301, the heat inside the moving component 107 and the photographing component 108 is conducted and dissipated, thereby quickly dissipating the heat of the surface of the camera inside the moving component 107 and the photographing component 108, so as to realize the function of the detection device to quickly dissipate the heat of the surface of the camera inside the moving component 107 and the photographing component 108, thereby avoiding the phenomenon that the surface of the camera of the detection device fails or jams due to excessive temperature after long-term use, making the detection device more efficient in photographing and detecting the surface of the circuit board body 109, and finally completing the use of the detection device.
