In the description and the accompanying drawings, specific embodiments of the present invention are specifically disclosed, which show some embodiments in which the principles of the present invention can be adopted, and it is to be understood that the present invention is not limited to the described embodiments.

[0045] The present invention first provides a sealing ring appearance detection device, Figure 1 This is a schematic diagram of the three-dimensional structure of the sealing ring appearance inspection device of the present invention. Figure 2 This is its top view. Figure 3 This is a schematic diagram of a rotary conveyor device according to a first embodiment of the sealing ring appearance inspection device of the present invention. Figure 4 This is a schematic diagram of a rotary conveyor device according to another embodiment. As shown, the sealing ring appearance inspection equipment includes a control device (not shown), a loading device 1, a rotary conveyor device 2, a first end surface inspection station 3, an outer lip inspection station 4, an inner lip inspection station 5, a side surface inspection station 6, a first flipping mechanism 7, a second end surface inspection station 8, a second flipping mechanism 9, a qualified product discharge device 10, and a rejected product discharge device 11. Among them, the rotating conveying device 2 includes a motor 201, a turntable 202, a motor 203 and a turntable 204. The turntable 204 is a hollow annular disc, and the turntable 202 is located at the center of the turntable 204; the turntable 204 is provided with at least two clamping mechanisms along its circle, and one of the clamping mechanisms 205 is marked as an example in the figure. The clamping mechanism 205 is connected to the turntable 202 through a connecting piece. The motor 201 drives the turntable 202 to rotate so as to drive the clamping mechanism 205 to clamp the sealing ring, and the motor 203 drives the turntable 204 to rotate so as to rotate and convey the sealing ring clamped by the clamping mechanism 205 for appearance inspection.

[0046] Figure 5 This is a partial schematic diagram of the clamping mechanism in the rotary conveying device of the sealing ring appearance inspection equipment of the present invention, combined with reference to Figure 3 、 Figure 5According to one embodiment of the present invention, the turntable 202 is provided with a long strip opening corresponding to each clamping mechanism, and one of the openings 2021 is marked in the figure as an example; the clamping mechanism 205 includes a clamping jaw 2051 and a clamping jaw 2052, one end of the clamping jaw 2051 is fixedly mounted on the moving block 2053, and one end of the clamping jaw 2052 is fixedly mounted on the moving block 2054, the other end of the moving block 2053 connecting the clamping jaw 2051 is hinged to a connecting rod 2055, and the other end of the moving block 2054 connecting the clamping jaw 2052 is hinged to a connecting rod 2056, and the connecting rod 2055 and the connecting rod 2056 are hinged together on the connecting block 2057, and the other end of the connecting rod 2055 and the connecting rod 2056 are hinged to the connecting block 2057 through a pulley sliding connection in the opening 2021. Thus, when the motor 201 drives the turntable 202 to rotate, the pulley rolling in the opening 2021 drives the connecting block 2057 forward. The forward-moving connecting block 2057 pushes the hinged connecting rods 2055 and 2056, thereby driving the moving blocks 2053 and 2054 to move to the sides, thereby driving the clamping jaws 2051 and 2052 to open. By controlling the rotation range of the turntable 202 driven by the motor 201, the opening range of the clamping jaws 2051 and 2052 can be adjusted. By adjusting the clamping space, it is possible to adapt to clamping various specifications of sealing rings, avoid the need to replace each clamping mechanism on the turntable 204 in batches, and thus improve the practicality of the detection equipment, reduce costs, and improve efficiency.

[0047] Combined with reference Figure 4 、 Figure 5According to another embodiment of the present invention, the turntable 202 is hinged with a connecting rod corresponding to each clamping mechanism, and one of the connecting rods 206 is marked in the figure as an example; the clamping mechanism 205 includes a clamping jaw 2051 and a clamping jaw 2052, one end of the clamping jaw 2051 is fixedly mounted on the moving block 2053, and one end of the clamping jaw 2052 is fixedly mounted on the moving block 2054, the other end of the moving block 2053 connecting the clamping jaw 2051 is hinged to the connecting rod 2055, and the other end of the moving block 2054 connecting the clamping jaw 2052 is hinged to the connecting rod 2056, and the connecting rod 2055 and the connecting rod 2056 are hinged together on the connecting block 2057, and the connecting block 2057 is hinged to the connecting rod 2055 and the other end of the connecting rod 2056 is hinged to the connecting rod 206. Thus, when the motor 201 drives the turntable 202 to rotate, the connecting rod 206 hinged on the turntable 202 drives the connecting block 2057 forward. The forward-moving connecting block 2057 pushes the hinged connecting rods 2055 and 2056, thereby driving the moving blocks 2053 and 2054 to move to the sides, thereby driving the clamping jaws 2051 and 2052 to open. By controlling the rotation range of the turntable 202 driven by the motor 201, the opening range of the clamping jaws 2051 and 2052 can be adjusted. By adjusting the clamping space, it can adapt to clamping various specifications of sealing rings, avoiding the need to replace each clamping mechanism on the turntable 204 in batches, thereby improving the practicality of the detection equipment, reducing costs and improving efficiency.

The inspection station setting of the other end face is the same as that of the first end face inspection station; the rotary conveying device 2 continues to clamp the sealing ring and transport it to the second end face inspection station 8 for inspection of the other end face, and then the rotary conveying device 2 continues to clamp the sealing ring and transport it to the second flipping station, and the sealing ring is flipped by another flipping mechanism 9. The specific structure of the flipping mechanism 9 is consistent with that of the flipping mechanism 7; finally, the rotary conveying device 2 continues to clamp the sealing ring and transport it to the qualified product unloading device 10, and the qualified sealing rings are collected by the collecting mechanism of the unloading device; when there is a sealing ring that fails the inspection, the rotary conveying device 2 continues to clamp the unqualified sealing ring and transport it to the unqualified product unloading device 11 for sorting.
