[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] See Figures 1-4, An external structure detection device for a DOB light source, comprising a machine base 10. A conveying mechanism 20 for driving a DOB light source board to be conveyed in a first direction is arranged on the machine base 10. A positioning component 30 and a position correction component 40 are arranged on the machine base 10. The positioning component 30 is used to stop the movement of the DOB light source board in the first direction. The position correction component 40 is used to push the DOB light source board to move in a second direction. A moving component 50 is arranged above the conveying mechanism 20. A visual detection component 60 for visually scanning the DOB light source board is installed on the moving component 50. The moving component 50 can drive the visual detection component 60 to move in the first direction and the second direction.

[0024] The utility model adopts a conveying mechanism to realize automatic conveying and detection. Under the action of the positioning component and the position correction component, it can position and correct the position of the DOB light source board on the conveying mechanism for detection. During detection, the moving component drives the visual detection component to move in the first direction and the second direction. Under the moving action, the visual detection component can scan the DOB light source board and transmit the scanned image to an external control terminal for image recognition and comparison through the external control terminal to determine whether there are missing components or incorrect installation positions on the components of the DOB light source board substrate. When the conveying is completed, the positioning component releases the position constraint on the DOB light source board, and the conveying mechanism conveys the DOB light source board that has completed the detection to the next working station. The utility model uses a machine to scan the DOB light source board and transmit the scanned image to an external control terminal, which can improve the detection efficiency, reduce manual operation, and realize the detection of mass-produced products.

[0025] See Figure 2 , The conveying mechanism 20 is composed of a plurality of conveying rollers 210.

After the detection is completed, the blocking baffle 320 is driven by the linear drive element 310 to move downward to release the blockage, so that the DOB light source board can continue to move along the first direction.
