[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1, referring to Figure 1-4 An imaging device based on the vision of a welding probe includes a welding probe body 1 and a housing 2. The housing 2 is fixedly connected to the welding probe body 1 through an electric clamping mechanism. An industrial camera 3 is connected to the housing 2 through an adjustment mechanism. The industrial camera 3 is based on vision detection technology and can capture images of the welding area in real time and accurately during the welding process to achieve effective monitoring of welding quality.

[0027] Specifically, the adjustment mechanism includes a fixed cover 4 fixedly connected to the side wall of the housing 2, a first stepper motor 5 fixedly installed on one outer wall of the fixed cover 4, a worm gear 6 fixedly mounted on the output shaft of the first stepper motor 5, an angle adjustment shaft 7 rotatably installed inside the fixed cover 4, a worm wheel 8 fixedly mounted on the angle adjustment shaft 7, a turntable 9 coaxially welded to the outer end of the angle adjustment shaft 7, and a telescopic rod structure fixed to the side wall of the turntable 9.

[0028] Furthermore, the worm 6 and the worm wheel 8 mesh with each other and are both located inside the fixed cover 4, and the output shaft of the first stepper motor 5 passes through one side of the fixed cover 4;

[0029] Furthermore, the telescopic rod structure includes a hollow rod 10 fixedly connected to the side wall of the turntable 9, an inverted T-shaped slide rod 11 slidably connected to the hollow rod 10, and a butterfly locking screw 12 threadedly connected to the lower part of one side of the hollow rod 10. The industrial camera 3 is fixedly installed on the bottom outer wall of the inverted T-shaped slide rod 11.

[0030] Furthermore, the surface of the inverted T-shaped slide bar 11 is provided with equally spaced threaded locking grooves 13, and the butterfly locking screw 12 is threadedly connected to one of the threaded locking grooves 13, which facilitates locking after the length adjustment is completed;

[0031] In this embodiment, when capturing images of the welding area, the first step motor 5 drives the worm gear 6 to rotate. Subsequently, the worm wheel 8, which meshes with the worm gear 6, drives the turntable 9 at one end of the angle adjustment shaft 7 to rotate, thereby enabling flexible adjustment of the shooting angle of the industrial camera 3. Moreover, by loosening the butterfly locking screw 12, the inverted T-shaped slide bar 11 can slide up and down within the hollow rod 10 to flexibly adjust the length of the entire telescopic rod structure. After adjustment, tightening the butterfly locking screw 12 again locks the length, thus enabling flexible adjustment of the shooting distance of the industrial camera 3.

[0032] Example 2, refer to Figure 1-2 and Figure 5-6 This embodiment is an optimization based on embodiment 1. Specifically, the electric clamping mechanism includes a bidirectional screw 14 that is rotatably mounted through the housing 2, two centering blocks 15 that are symmetrically screwed to the two opposite threaded ends of the bidirectional screw 14, two V-shaped clamping blocks 16 that are symmetrically welded to the outer wall of the adjacent side of the two centering blocks 15, a guide shaft 17 that is fixed through the housing 2, and a drive assembly provided on the housing 2.

[0033] Furthermore, both V-shaped clamps 16 are clamped on the welding probe body 1, and both centering blocks 15 are provided with guide holes that are slidably connected to the guide shaft 17. Through the guiding effect of the guide holes, the stability of the centering movement of the two V-shaped clamps 16 can be guaranteed.

[0034] Furthermore, the drive assembly includes a second stepper motor 18 fixedly mounted on one outer wall of the housing 2, a drive gear 19 fixedly mounted on the output shaft of the second stepper motor 18, and a transmission gear 20 fixedly mounted in the middle of the bidirectional screw 14. The output shaft of the second stepper motor 18 passes through one side of the housing 2, and the drive gear 19 and the transmission gear 20 mesh with each other and are both located inside the housing 2.

[0035] In this embodiment, the second stepper motor 18 controls the drive gear 19 to rotate, and the transmission gear 20 meshing with the drive gear 19 drives the bidirectional screw 14 to rotate. Under the guidance of the guide shaft 17, the two centering blocks 15 threadedly connected to the bidirectional screw 14 drive the two V-shaped clamps 16 to center and clamp onto the surface of the welding probe body 1 to achieve a locking effect. This completes the stable installation of the entire shooting device. In subsequent disassembly, the two V-shaped clamps 16 can be moved away from each other by the reverse rotation of the second stepper motor 18 to achieve the locking effect, thus completing the quick disassembly of the entire shooting device.

[0036] Working principle: First, the second stepper motor 18 controls the drive gear 19 to rotate. Then, the transmission gear 20, which meshes with the drive gear 19, drives the bidirectional screw 14 to rotate. Under the guidance of the guide shaft 17, the two centering blocks 15, which are threadedly connected to the bidirectional screw 14, drive the two V-shaped clamping blocks 16 to center and clamp onto the surface of the welding probe body 1 to achieve a locking effect. In this way, the entire shooting device can be stably installed.

[0037] Secondly, when capturing images of the welding area, the first step motor 5 drives the worm gear 6 to rotate, and then the worm wheel 8 meshing with the worm gear 6 drives the turntable 9 at one end of the angle adjustment shaft 7 to rotate, thereby enabling flexible adjustment of the shooting angle of the industrial camera 3. Furthermore, by loosening the butterfly locking screw 12, the inverted T-shaped slide bar 11 can slide up and down within the hollow rod 10 to flexibly adjust the length of the entire telescopic rod structure. After adjustment, tightening the butterfly locking screw 12 again will lock the length, thus enabling flexible adjustment of the shooting distance of the industrial camera 3.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
