Technical Field

[0001] This utility model relates to the field of mechanical parts inspection technology, and in particular to a robotic arm structure for visual inspection. Background Technology

[0002] Surface defect detection of mechanical parts plays a crucial role in quality control and production management. Surface defect detection utilizes machine vision technology, employing optical principles to inspect the surface of products. When light shines on the product surface, various defects reflect and refract, producing different image changes. For example, scratches, cracks, burrs, flash, and indentations cause changes in light reflection and refraction, thus appearing in the image.

[0003] However, existing testing devices are not flexible enough to fully scan the surface of parts, which greatly affects the testing accuracy. Utility Model Content

[0019] This utility model provides a robotic arm structure for visual inspection, including a fixed arm 1, an adjustment mechanism, a rotating rod 2, a scanning device 3, a nozzle 4, and a rotating assembly.

The aforementioned solution solves the problem that existing inspection devices have poor flexibility, making it difficult to fully scan the surface of parts, which greatly affects the inspection accuracy.

[0020] In this specific embodiment, the two fixing plates 6 are fixedly connected to the fixing arm 1 and located on one side of the fixing arm 1. One end of the connecting plate 7 is rotatably connected to the two fixing plates 6, and the other end of the connecting plate 7 is fixedly connected to the rotating arm 5 and located at one end of the fixing arm 1. The two rotating blocks 8 are rotatably connected to the fixing arm 1 and the rotating arm 5 respectively and are respectively disposed on one side of the fixing arm 1 and the rotating arm 5. The two ends of the telescopic rod 9 are fixedly connected to the two rotating blocks 8 respectively and are located at one end of the rotating blocks 8. The limiting component is disposed above the telescopic rod 9 to fix the fixing arm 1 in an appropriate position. During adjustment, the telescopic rod 9 extends or retracts, and the two rotating blocks 8 want to rotate. At the same time, the telescopic rod 9 pulls one end of the rotating arm 5 to move, so that the rotating arm 5 rotates around the connecting plate 7 and the fixing plate 6.

[0021] The fixed plate 10 is fixedly connected to the fixed arm 1 and is located above the fixed arm 1. One end of the telescopic column 11 is fixedly connected to the fixed plate 10, and the other end of the telescopic column 11 is fixedly connected to the limiting block 13. The spring 12 covers the surface of the telescopic column 11. The rotating member 14 is located below the limiting block 13. When the telescopic rod 9 rotates to a certain position, the rotating member 14 contacts the telescopic rod 9. The telescopic column 11 and the spring 12 push the telescopic rod 9 to prevent the telescopic rod 9 from rotating above the fixed arm 1.

[0022] Secondly, the mounting block 15 is fixedly connected to the limiting block 13 and located below the limiting block 13. The rotating plate 16 is rotatably connected to the mounting block 15 and located below the mounting block 15. The two rotating rollers 17 are rotatably connected to the rotating plate 16 and located below the rotating plate 16. The rotating rollers 17 are in contact with the telescopic rod 9. The telescopic rod 9 continues to extend. The rotating rollers 17 move on the surface of the telescopic rod 9 to prevent the telescopic rod 9 from rotating above the fixed arm 1.

[0023] Secondly, the rotating rod 2 is rotatably connected to the rotating arm 5 and is located on one side of the rotating arm 5. The scanning device 3 is fixedly connected to the rotating rod 2 and is located at one end of the rotating rod 2. The nozzle 4 is fixedly connected to the rotating rod 2 and is located on one side of the scanning device 3. The rotating assembly is arranged on one side of the rotating rod 2. The scanning device 3 scans the surface of the rotating rod 2. The nozzle 4 is connected to an air pump to blow away dust and impurities on the surface of the workpiece, thereby improving the scanning accuracy.

[0024] In addition, a second gear 20 is provided at one end of the rotating rod 2. The motor 18 is fixedly connected to the rotating arm 5 and located on one side of the rotating arm 5. The first gear 19 is fixedly connected to the output end of the motor 18. The first gear 19 meshes with the second gear 20. The motor 18 drives the first gear 19 to rotate, and the first gear 19 drives the second gear 20 to rotate, so that the rotating rod 2 rotates accordingly, and the scanning device 3 rotates accordingly, thereby improving the working range of the scanning device 3.

[0025] When using this utility model, the fixed arm 1 is fixed in an appropriate position. During adjustment, the telescopic rod 9 extends or retracts, and the two rotating blocks 8 rotate. At the same time, the telescopic rod 9 pulls one end of the rotating arm 5 to move, so that the rotating arm 5 rotates around the connecting piece 7 and the fixed piece 6. The rotating roller 17 contacts the telescopic rod 9. The telescopic column 11 and the spring 12 push the telescopic rod 9 to prevent the telescopic rod 9 from rotating above the fixed arm 1. The first gear 19 drives the second gear 20 to rotate, so that the rotating rod 2 rotates accordingly, and the scanning device 3 rotates accordingly, thereby improving the working range of the scanning device 3.
