Technical Field
[0001] This utility model relates to the field of turntable measuring equipment technology, specifically a vision-based turntable measuring equipment. Background Technology
[0002] A vision turntable measurement system is an automated system based on computer vision technology, primarily used for product inspection and quality control. It typically consists of a rotating turntable and a set of high-resolution cameras to capture and analyze images of the product. The main components include the main body, motion mechanism, and control unit. Connecting devices include a GOI (Go-In-the-Box) main control board, motor drive board, cameras, sensors, and an industrial computer. The working principle of the vision turntable measurement system is that the rotating turntable moves the product to the inspection station, where the high-resolution cameras photograph and inspect the product. The system usually includes a 3D camera on top and a conventional camera on the bottom, allowing for multi-angle inspection of the product. After inspection, qualified and unqualified products are separately picked up and diverted to different output channels.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution:
[0021] The vision-based rotary measuring device includes a main body 1, a robotic arm 4 inside the main body 1, an indexing turntable 6 inside the main body 1, a plurality of positioning fixtures 7 arranged in a ring on the upper end of the indexing turntable 6, the upper ends of the plurality of positioning fixtures 7 all contacting workpieces 5, a mounting frame 8 inside the main body 1, a plurality of light sources 9 arranged in a ring on the side wall of the mounting frame 8, a plurality of lenses 10 arranged in a ring on the side wall of the mounting frame 8, and a camera 11 at one end of each of the plurality of lenses 10.
[0022] For example, the robot arm 4 picks up the workpiece 5 at the end of the guide rail 3 and places the workpiece 5 into the positioning fixture 7 on the indexing turntable 6. The positioning fixture 7 fixes the workpiece 5. The indexing turntable 6 drives the positioning fixture 7 to rotate. When the positioning fixture 7 moves to one side of the mounting frame 8, the light source 9 is turned on. The light source 9 illuminates the workpiece 5 on the positioning fixture 7. The camera 11 detects the workpiece 5 through the lens 10. Multiple cameras 11 can detect the workpiece 5 from multiple angles, which can improve the detection effect. The camera 11 detection system can provide highly consistent and accurate measurement results. At the same time, the camera 11 detection system can quickly complete the detection task, significantly improving production efficiency.
[0023] The main body 1 of the testing equipment is equipped with a fixed frame 12, and multiple mounting plates 13 arranged in a ring are provided on the upper end of the fixed frame 12.
[0024] For example, the mounting bracket 12 mounts the mounting plate 13.
[0025] Adjustment plates 14 are provided on the side walls of multiple mounting plates 13.
[0026] For example, the interior of the regulating plate 14 is hollow to facilitate airflow.
[0027] The upper end of the adjusting plate 14 is threadedly connected to an air pipe interface 15, and the lower end of the adjusting plate 14 is fixedly connected to an air outlet pipe 16.
[0028] For example, the air pipe interface 15 is connected to an external air pipe, and the airflow passes through the inside of the regulating plate 14 and blows the workpiece 5 off through the air outlet pipe 16.
[0029] The main body 1 of the detection equipment is internally fixedly connected with a plurality of ring-shaped support blocks 17, and a collection box 18 is slidably connected to the upper end of each of the plurality of support blocks 17.
[0030] For example, the top of the support block 17 is set as a ramp so that the collection box 18 can be stably placed on the top of the support block 17.
[0031] The main body 1 of the testing equipment is equipped with a vibrating plate 2 on its side wall, and a guide rail 3 is fixedly connected to the side wall of the vibrating plate 2.
[0032] For example, the workpiece is placed inside the vibratory feeder 2 and the vibratory feeder 2 is turned on. The vibratory feeder 2 realizes the automatic conveying and sorting of the workpiece 5 through vibration. The workpiece 5 enters the guide rail 3 from inside the vibratory feeder 2. The guide rail 3 transports the sorted workpiece. The vibratory feeder 2 improves production efficiency and product quality through efficient conveying and sorting functions.
[0033] Working principle: When using this utility model, the workpiece is placed inside the vibratory feeder 2, and the vibratory feeder 2 is turned on. The vibratory feeder 2 realizes the automatic conveying and sorting of the workpiece 5 through vibration. The workpiece 5 enters the guide rail 3 from inside the vibratory feeder 2. The guide rail 3 transports the sorted workpieces. The robot arm 4 picks up the workpiece 5 at the end of the guide rail 3 and puts the workpiece 5 into the positioning fixture 7 on the indexing turntable 6. The positioning fixture 7 fixes the workpiece 5. The indexing turntable 6 drives the positioning fixture 7 to rotate. When the positioning fixture 7 moves to one side of the mounting frame 8, the light source 9 is turned on. The light source 9 illuminates the workpiece 5 on the positioning fixture 7. The camera 11 detects the workpiece 5 through the lens 10. Multiple cameras 11 detect the workpiece 5 from multiple angles, which can improve the detection effect.
[0034] After the camera 11 completes the inspection of the workpiece, the indexing turntable 6 drives the positioning fixture 7 to rotate. The indexing turntable 6 rotates at a fixed angle, so that the positioning fixture 7 rotates to the position of the evenly distributed mounting plates 13. The interior of the adjusting plate 14 is hollow to facilitate the flow of air. The air pipe interface 15 is connected to the external air pipe. The airflow passes through the interior of the adjusting plate 14 and blows the workpiece 5 off through the air outlet pipe 16. The top of the support block 17 is set as a slope so that the collection box 18 can be stably placed on the top of the support block 17. Multiple collection boxes 18 in different positions collect different workpieces. After the camera 11 completes the inspection, it transmits the data to the controller. The controller controls the air outlet pipe 16 in different positions to blow air out and blow different workpieces 5 into the interior of different collection boxes 18.
