[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] This utility model provides a technical solution: such as Figure 1As shown in this embodiment, the adjustment mechanism of a 3D visual inspection device for optical imaging includes an inspection platform 1. Guide structures 2 are installed at both the front and rear ends of the inspection platform 1. A visual inspection adjustment device 3 is bolted to the rear side of the inspection platform 1. A feed plate 12 is fixedly connected to one end of the inspection platform 1. A control template 11 is provided in the middle of the outer surface of the front side of the inspection platform 1.

[0029] like Figure 2 and Figure 3 As shown, the guide structure 2 includes a cylinder 21, which is located at both ends of the detection table 1. Connecting rods 22 are slidably connected to the left and right ends of both sides of the front and rear sides of the detection table 1. One end of each connecting rod 22 facing each other is connected to the cylinder 21, and the other end of each connecting rod 22 is fixedly connected to a mounting frame 23. Guide rollers 24 are arranged in the mounting frame 23. Two adjacent guide rollers 24 are connected by a transmission belt. By installing the guide structure 2, the position of the guide rollers 24 on both sides can be adjusted according to the size of the object being detected, which facilitates the transfer of the object being detected while avoiding deviation during the transfer process, thereby improving the detection effect.

[0030] like Figure 1 and Figure 4 As shown, the visual inspection adjustment device 3 includes a side plate 31, a lead screw 32 is provided at the left end of the side plate 31, and a fixed rod 33 is provided at the right end of the side plate 31. A movable block 34 is provided on the outer wall of the lead screw 32 and the fixed rod 33. A fixed plate 35 is fixedly connected to the front outer surface of the movable block 34. An angle adjustment component 36 is rotatably installed on the fixed plate 35. An installation groove 351 is provided on the fixed plate 35, and a limit groove 352 is provided on the front side of the fixed plate 35. The detection camera 361 can adjust its height position according to the height of the object being inspected, thereby adjusting the viewing angle and focal length of the camera 361, improving the accuracy and efficiency of the inspection, and better adapting to objects of different sizes, ensuring clear images, and avoiding missed or false detections.

[0031] like Figure 4 and Figure 5 As shown, the angle adjustment assembly 36 includes a detection camera 361. A top plate 362 is bolted to the top side of the detection camera 361. A rotating rod 363 is fixedly connected to the middle of the top plate 362. The rotating rod 363 is rotatably connected in the mounting groove 351. A sleeve 364 is fixedly connected to the front edge of the rotating rod 363. A limit plate 366 is slidably connected to the front end of the rotating rod 363. A spring 365 is embedded between the sleeve 364 and the limit plate 366. The limit plate 366 is engaged with the limit groove 352. The detection camera 361 can adjust its angle by rotating the rod 363, thereby changing the shooting range and angle of the camera 361 to adapt to different monitoring or shooting needs.

[0032] This utility model provides an adjustment mechanism for a light imaging 3D visual inspection device. The specific working principle is as follows: Based on the required shooting range and viewing angle of the inspection camera 361, the limiting plate 366 is pulled away from the mounting groove 352 and rotated until the angle of the inspection camera 361 after rotation meets the requirements. Then, the limiting plate 366 is released, allowing the spring 365 to reset and engage with the limiting groove 352. Based on the viewing angle detected by the inspection camera 361 and the height position of the focus adjuster, the motor rotates the lead screw 32, causing the movable block 34 to rise and fall on the lead screw 32 and the fixed rod 33, thus adjusting the height of the inspection camera 361. Then, based on the size of the inspection object, the cylinder 21 is activated, causing the front and rear guide rollers 24 to contact the sides of the inspection object. The motor is then activated, causing the guide rollers 24 to rotate, thereby driving the inspection object and enabling the inspection camera 361 to perform light imaging 3D visual inspection of the inspection object.
