[0023] Referring to Figures 1-5 , the base plate 1 is a basic support component of the entire positioning assembly, and the top of the base plate 1 is rotationally connected with the rotating disc 2 through a rotating column. The rotating disc 2 can rotate around its own axis under the action of the rotating column, and the rotating disc 2 is internally provided with a plurality of storage grooves 3 for placing beamsplitter elements 30. Each storage groove 3 is provided with a U-shaped plate 54 and a clamping frame 5, and the beamsplitter element 30 is clamped in the clamping frame 5, and the clamping frame 5 is rotationally arranged in the U-shaped plate 54, so that the beamsplitter element 30 can rotate within a certain range to realize multi-angle detection.

[0024] Referring to Figure 1 and Figure 2The detection box 14 is fixed on the top of the base plate 1, and one side of the rotating disc 2 extends into the detection box 14 to provide a relatively closed space for detection, reducing the interference of the external environment on the detection.

[0025] With reference to Figure 4 and Figure 5 The clamping structure includes a hollow tube 4 rotating through the inner wall of one side of the placing groove 3 and a sliding rod II 15 sliding through the inner wall of one side of the placing groove 3. An annular air bag 7 is fixed on the inner wall of the clamping frame 5 (where the inner wall groove of the clamping frame 5 is transitioned by a round corner, and the annular air bag 7 can be made of nitrile rubber or fluororubber), and the annular air bag 7 can clamp the spectroscope element 30 located therein after inflation. One end of the hollow tube 4 is fixedly connected with one side of a U-shaped plate member 54, and the other end is fixedly connected with a connecting hose 8, one end of the connecting hose 8 penetrates the clamping frame 5 and the U-shaped plate member 54 and is fixedly connected with the annular air bag 7. An annular base 6 located below the annular air bag 7 is fixed in the clamping frame 5.

[0026] With reference to Figure 1 and Figure 7 A piston sheet 9 is sealingly and slidingly connected in the hollow tube 4, one end of the piston sheet 9 away from the connecting hose 8 is fixed with a sliding rod I 10 (chromium-plated), and one end of the sliding rod I 10 slidingly extends to one side of the hollow tube 4. The sliding rod I 10 cooperates with the notched ring body 12 and the guide slope 13, when the rotating disc 2 rotates, the sliding rod I 10 abuts against the inner wall of the notched ring body 12 under the guidance of the guide slope 13, and as the rotating disc 2 continues to rotate, the sliding rod I 10 pushes the piston sheet 9 to move towards the connecting hose 8 under the action of the notched ring body 12. The piston sheet 9 injects air in the hollow tube 4 into the annular air bag 7 through the connecting hose 8, so that the annular air bag 7 inflates, thereby clamping the spectroscope element 30. In order to reset the piston sheet 9, a tension spring I 11 is sleeved on the outer wall of the sliding rod I 10, and the two ends of the tension spring I 11 are fixedly connected with one side of the piston sheet 9 and one side inner wall of the hollow tube 4 through spring seats.

The inner wall of one side of the storage groove 3 is provided with an avoiding groove 19, when the pressing piece 16 needs to move outward, it can be accommodated in the avoiding groove 19, so as to avoid the pressing piece 16 hindering the rotation of the U-shaped plate 54, and the double fixation of the annular air bag and the pressing piece can improve the stability.

[0028] With reference to Figure 6 , Figure 8 and Figure 9 , the first detection assembly comprises a fixed disc 31 fixedly sleeved on the outer wall of the hollow tube 4, and a cam member 25 rotating on one side of the rotating disc 2, and the cam member 25 is sleeved on the outer wall of the sliding rod II 15.

When the sliding rod II 15 moves outward, the sliding balls 26 start at the intersection position of the spiral groove 24 and the strip-shaped groove 23, and as the sliding rod II 15 continues to move, the cooperation between the spiral groove 24 and the sliding ball 26 drives the cam member 25 to rotate.

[0029] With reference to Figure 8 and Figure 9 , the cam member 25 is arranged in the frame body 27 and cooperates with the frame body 27, when the cam member 25 rotates, the outer contour thereof interacts with the inner wall of the frame body 27, thereby driving the frame body 27 to ascend and descend. The bottom of the frame body 27 is fixedly connected with a plurality of tension springs III 29 through spring seats, and the bottom ends of the plurality of tension springs III 29 are fixedly connected with the inner wall of the bottom of the protective cover 28 through spring seats. The elastic coefficient of the tension spring III 29 ranges from 8N / mm to 20N / mm, and the tension spring III 29 provides a restoring force for the frame body 27, so that the frame body 27 can reciprocatingly move up and down during the rotation of the cam member 25.

[0030] When the frame body 27 is lifted, the fixed disc 31 and the hollow tube 4 are driven to reciprocatingly rotate and swing by the connecting rod 32. Since the hollow tube 4 is fixedly connected with the U-shaped plate 54, and the clamping frame 5 is rotatably arranged in the U-shaped plate 54, the rotation and swing of the hollow tube 4 can drive the spectroscope element 30 clamped in the clamping frame 5 to synchronously rotate, so that the industrial camera 45 can detect from different angles of the spectroscope element 30, and the detection accuracy is improved.

The elastic coefficient of the torsion spring 40 ranges from 10 N / mm to 25 N / mm, when the rotating shaft 39 is rotated by external force, the torsion spring 40 is twisted and deformed to store elastic potential energy, and when the external force disappears, the torsion spring 40 releases the elastic potential energy to reset the rotating shaft 39.

[0032] The moving base 21 drives the rotating shaft 39 and the circular disc 42 to rotate through the traction rope 41, the circular disc 42 drives the lifting column 34 to reciprocatingly move up and down through the cooperation of the pin shaft member 43 and the lifting frame 44. When the lifting column 34 rises and extends into the storage groove 3, the magnet I 35 is attached to the magnet II 37, and when the lifting column 34 moves up and down in the later stage, the magnet I 35 and the magnet II 37 can drive the clamping frame 5 and the spectroscope element 30 to rotate in the U-shaped plate 54 through magnetic attraction force, so that the spectroscope element 30 can be further detected at different angles, and the detection accuracy is improved.
