[0023] In the process of detecting the spherical gasket, firstly, the first conveying component 2 and the second conveying component 7 can be started to carry out the transportation work through the setting of the start-stop assembly 6, and the spherical gasket is transported by the left side of the first conveying component 2, so that the spherical surface is transported to the middle position of the first conveying component 2, and then the spherical gasket is transported and processed by the handling component 3 set at the side of the first conveying component 2 and the second conveying component 7, and the first electric push rod 302 can be driven to rotate by the driving motor 301. In addition, the output end of the first electric push rod 302 can drive the second electric push rod 303 to move its position. In addition, the manipulator 304 set at the bottom of the second electric push rod 303 can carry and process the spherical gasket, so that it can be transported to the top position of the placement rack 16, and the start-stop assembly 6 set on one side of the second conveying component 7 is used to start the linear conveying component 701 on the left to carry out the transportation work, so that the conveying rack 10 can be By moving the linear conveying component 701 on the left, the slider 11 arranged at the bottom of the conveying frame 10 will slide inside the slide groove 703, and the connecting rack 704 will also be meshed with the rotating gear 12, so that the rotating gear 12 can be rotated, resulting in the rod threadedly connected at the top center position of the rotating gear 12 driving the extrusion plate 13 to squeeze the bottom end position of the elastic airbag 14, so that the gas inside the elastic airbag 14 can be transported to the inside of the connecting plate 17 through the gas hose 15, and the spherical gasket can be limited by the driving mechanism at this time. In addition, the driving mechanism works by the gas transported by the gas hose 15, so that the rotating sleeve 18 and the piston rod 19 are filled with gas, so that the piston rod 19 can move relative to the internal position of the rotating sleeve 18 through the guide block 20 and the return spring 21, so that the spherical gasket can be limited.

[0024] Embodiment 2: In order to solve the problem that the detection device currently on the market needs to detect the front and back positions of the gasket when detecting the spherical gasket, the adsorption process of the suction cup is easily blocked, which makes the detection more complicated. Figure 1 -Attached Fig. 9There are two groups of limit mechanisms symmetrically distributed about the vertical center line of the top of the placement rack 16. The end of one group of rotating sleeves 18 is fixed to the output end position of the fixed motor 23. A plurality of groups of fitting grooves 2201 are opened inside the clamping disk 22. The clamping disk 22 is arranged on the inner side of the top of the placement rack 16. Two groups of guide grooves 24 are slidingly arranged on the top of the placement rack 16. A lifting assembly 25 is arranged inside the guide groove 24. The lifting assembly 25 includes a accommodating rod 2503 fixed inside the guide groove 24. The inside of the accommodating rod 2503 is connected to the end of the cross bar 2502 through a spring. A wedge block 2501 is fixed to the outer end of the cross bar 2502. The width of the wedge block 2501 is smaller than the width of the fitting groove 2201.

[0025] In the step of limiting the spherical gasket, there is another phenomenon. When the two groups of clamping plates 22 move relative to each other, the edge position of the clamping plate 22 will squeeze the wedge 2501 of the lifting assembly 25, so that the wedge 2501 extends and slides inside the accommodating rod 2503 through the setting of the cross bar 2502 and the spring, and the wedge 2501 is inclined, so that the height of the spherical gasket can be adjusted. At this time, when the fixed motor 23 is started, the fixed motor 23 will drive the clamping plate 22 and the rotating sleeve 18 to rotate, so that the fitting groove 2201 opened by the clamping plate 22 can overlap with the wedge 2501, so that the wedge 2501 can be reset. At this time, the spherical gasket will also be centered, and the spherical gasket can also be detected from different angles. This process is detected and processed when the second conveying assembly 7 on the left is in a stopped state.

[0026] Embodiment 3: In order to facilitate the classification of the spherical gaskets after detection, please refer to the attached Figure 1 -Attached Figure 7 and attached Fig.10 Two groups of rollers 27 are rotatably arranged at the bottom of the conveying frame 10, and a screw 28 is fixed at the axial end of the roller 27. The outer side of the screw 28 is connected to the inner wall of the placement frame 16 through a torsion spring 29, and the outer side of the screw 28 is threadedly connected to the inside of the piston square plate 30. The inside of the piston square plate 30 is slidably arranged in the cavity inside the conveying frame 10, and the top position of the cavity is connected to the bottom end of the supporting telescopic rod 32 through an air pipe 31. The thread directions of the sliders 11 at both ends of the front and rear groups of rollers 27 are oppositely arranged, and the supporting telescopic rod 32 is composed of a group of thick tubes and a group of thin tubes, and the thin tubes are against the bottom edge of the placement frame 16.

[0027] After the detection is completed, the conveying process is carried out through the arc conveying component 702 and the right-hand slide groove 703. When it moves to the terminal position of the right-hand slide groove 703, it can be fixed to one side of the connecting rack 704 through the inner wall of the right-hand slide groove 703, so that the limit release process can be conveniently performed. Since the right-hand slide groove 703 has been in the conveying state, the conveying frame 10 no longer moves at this time. At this time, the roller 27 will roll through the right-hand slide groove 703, so that the screw 28 can drive the torsion spring 29 to rotate elastically, and the piston square plate 30 slides inside the conveying frame 10, so that the gas inside the cavity can realize the height adjustment of the support telescopic rod 32 through the gas pipe 31. At this time, a group of front support telescopic rods 32 will retract, And the supporting telescopic rod 32 on the rear side will be raised, so that the placement rack 16 can adjust its angle through the connecting shaft 26, so that the spherical gasket will tilt, so that qualified spherical gaskets can be transported through the right side of the first conveying component 2, and unqualified spherical gaskets will be transported and processed through a group of conveying components 3, and the unqualified spherical gaskets will fall into the waste collection box 9 through the collecting bevel bar 8; when the placement rack 16 is transported, it can be transported and processed through the set conveying component 3. At this time, the sliders 11 set on both sides of the placement rack 16 can be conveniently taken out through the slide groove 703, and the placement rack 16 will fall into the linear conveying component 701 on the left, which is convenient for continuous use.
