[0026] like Figures 1 to 9 As shown, the present invention provides an embedded imaging diffuse light source for detecting surface defects of a first object and a second object set at intervals, including a shell 1, a first light source 2, a second light source 3, a first shooting component 4, a second shooting component 5, a first adjustment device 6 and a second adjustment device 7. The shell 1 has a first chamber 11 and a second chamber 12, and the second chamber 12 is provided with a first movable groove 121 and a second movable groove 122. The inner wall of the second chamber 12 is provided with a diffuse reflection layer; the first light source 2 is provided in the first chamber 11 and is connected to the shell 1, and is used to project fill light onto the surface of the first object; the second light source 3 is provided in the first chamber 11 and is connected to the shell 1, and is used to project fill light onto the surface of the second object. Projecting fill light; the first shooting component 4 is arranged in the first moving groove 121 and is slidably connected to the shell 1, for taking a surface photo of the first object; the second shooting component 5 is arranged in the second moving groove 122 and is slidably connected to the shell 1, for taking a surface photo of the second object; the first adjustment device 6 is connected to the first shooting component 4, for driving the first shooting component 4 to move along the first moving groove 121; the second adjustment device 7 is connected to the second shooting component 5, for driving the second shooting component 5 to move along the second moving groove 122, wherein an annular light source 100 is provided in the second chamber 12, and the annular light source 100 faces the diffuse reflection layer to form a diffuse reflection light source to illuminate the first object and the second object.

[0027] By adopting the above technical solution, the ring light source 100 is directed toward the diffuse reflection layer. The light emitted by the ring light source 100 is irradiated onto the diffuse reflection layer, where it is reflected by the rough surface of the diffuse reflection layer to form diffuse reflection light. The diffuse reflection light is then irradiated onto the surfaces of the first object and the second object, making the illumination of the surfaces of the first object and the second object softer and more uniform, thereby facilitating the capture of higher-quality photos of the first object and the second camera assembly. Adjusting the first adjustment device 6 can adjust the relative position between the first camera assembly 4 and the first object, and adjusting the second adjustment device 7 can adjust the relative position between the second camera assembly 5 and the second object. The first camera assembly and the second camera assembly can be adjusted to the optimal shooting position for shooting, thereby improving the shooting quality of the photo. The first light source 2 can project fill light onto the surface of the first object; the second light source 3 can project fill light onto the surface of the second object.

[0029] Furthermore, the annular light source 100 is a backlight structure that uses special LEDs for lighting. Using a high thermal conductivity aluminum substrate as a carrier of the LEDs can improve welding strength, while using a high thermal conductivity heat dissipation adhesive is beneficial to the heat dissipation of the LEDs.

The design of the roller 9 allows the diffuse reflective film 8 to follow the movement of the first camera assembly, ensuring that the diffuse reflective film 8 can cover the remaining areas of the groove even if the first camera assembly 4 moves to any position within the groove. Similarly, the diffuse reflective film 8 can cover the portion of the second movable groove 122 where the lens of the second camera assembly 5 is not located, ensuring that this area still has a white background consistent with the diffuse reflective layer, improving the quality of diffuse reflection and ensuring that diffuse reflection is achieved in all areas of the second cavity.
