[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] An optical detection device with position adjustment function, see Figure 1-Figure 2, comprising a connecting arm 1, an industrial camera 2 (including a camera and a lens), a first annular light source 3, an adjustment plate 4, a connecting plate 5, and a second annular light source 6. The industrial camera 2 is connected to the connecting arm 1, with the lens of the industrial camera 2 facing downward, and the first annular light source 3 is arranged at the bottom of the industrial camera 2 and is concentrically arranged. One of the adjustment plate 4 and the connecting arm 1 is provided with a plurality of first connecting portions 11 arranged in a vertical direction, and the other is provided with a second connecting portion 41. The second connecting portion 41 can be horizontally slidably connected to any first connecting portion 11 so that the adjusting plate 4 can adjust its vertical position and can move horizontally. Specifically, the connecting arm 1 is provided with a plurality of rows of first connecting portions 11 arranged in a vertical direction. The first connecting portion 11 is preferably a plurality of first connecting holes arranged horizontally. The adjusting plate 4 is provided with first strip holes arranged in the left and right directions. A locking member such as a bolt is passed through the first connecting hole and the strip hole to connect the adjusting plate 4 to the connecting arm 1. Connecting the strip holes to the first connecting holes in different rows can adjust the height of the adjustment plate 4, thereby adjusting the height of the connecting plate 5 and the second annular light source 6. The adjustment plate 4 can be moved left and right relative to the locking member through the first strip hole, thereby changing its position in the left and right directions. The connecting plate 5 is connected to the adjustment plate 4 and is provided with an avoidance hole 51, through which the industrial camera 2 and the first annular light source are illuminated. The second annular light source 6 can be horizontally slidably connected to the bottom of the connecting plate 5. The moving direction of the second annular light source 6 is perpendicular to the moving direction of the adjustment plate 4. Specifically, the connecting plate 5 is provided with second strip holes 52 arranged in the front-to-back direction on both sides of the avoidance hole 51. The second strip holes 52 cooperate with the threaded holes of the second circular light source, and can also be fixed by bolts. By moving the position of the bolts in the second strip holes 52, its position in the front-to-back direction can be changed.

[0027] The height position of the adjustment plate 4 is changed by connecting it to the first connection holes in different rows. The left and right position of the adjustment plate 4 is adjusted through its first strip hole, and the front and rear position of the second ring light source 6 is adjusted through its second strip hole 52. Preferably, the industrial camera 2, the first ring light source 3, and the second ring light source 6 are arranged concentrically. In this way, the light from the two ring light sources can be evenly irradiated on the object to be measured, and the object to be measured can evenly reflect the reflected light to the camera, which is beneficial to improving the camera imaging stability, image difference, and detection effect. The position of multiple directions can be adjusted by multiple rows of first connection holes, first strip holes, and second strip holes 52, and the structure is simple.

[0028] In this embodiment, there are multiple first connection parts 11 and second connection parts 41, which can adjust the height position and left and right position, and at the same time, multiple first connection parts 11 and second connection parts 41 can be connected during assembly to improve assembly reliability.

[0029] In this embodiment, a connecting seat 53 is extended outward from the connecting plate 5 , and a light shielding plate 531 is provided on the connecting seat 53 . The light shielding plate 531 can block strong light during the detection process to protect the eyes of the operator.

[0030] Among them, the light shielding plate 531 is slidably connected to the connecting seat 53, so that it can not only block the strong light generated by the industrial camera 2 during the detection process, but also when using the second ring light source 6 of different sizes, the position of the light shielding plate 531 can be adjusted, which can avoid interference and reduce the space occupied while ensuring the shading effect.

[0031] There are two connecting bases 53, each connected to a light shielding plate 531. The light shielding plates 531 are L-shaped, and the two light shielding plates 531 are arranged facing each other and form a U-shape when spliced. The two light shielding plates 531 are arranged in a U-shape when assembled, which can block light from three directions and improve the protection effect. The two light shielding plates 531 partially overlap. In this way, when the second ring-shaped light source 6 is small, the two light shielding plates 531 will not interfere with each other when they are placed close together.

[0032] Among them, a third long hole is provided on the connecting seat 53, and a second connecting hole matching the third long hole is provided on the light shielding plate 531. The two holes can also be fixed and positioned by means of bolts.

[0033] The adjusting plate 4 and the connecting plate 5 are integrally formed L-shaped plates.

[0034] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
