[0039] An abandoned opening is also provided on the top surface of the workbench 1. The abandoned opening is located in the discharging group 5. Between the inspection tray 23

[0040] The inspection group 2 is arranged at the geometric center position on the top surface of the workbench 1.

[0041] The inspection group 2 includes a PLC control circuit and a servo motor controlled by the PLC control circuit.

[0042] In this solution, the PLC control circuit is prior art and will not be elaborated too much.

[0043] The servo motor is arranged inside the workbench 1 and at least partially extends to the top surface of the workbench 1. A transparent inspection tray 23 is also provided on the output end of the servo motor. An annular inspection lamp is also provided between the bottom surface of the inspection tray 23 and the workbench 1. The output end of the servo motor and the axis of the annular inspection lamp are arranged on the same axis.

[0044] Through the arrangement of the annular inspection lamp and the transparent inspection tray 23, it can be ensured that the rubber ring 6 can rotate along with the inspection tray 23 when the inspection tray 23 is driven by the servo motor, and the presence or absence of defects inside and outside the rubber ring 6 is inspected through the light emitted by the annular lamp.

[0045] As a preference: In order to be able to replace manual visual inspection, in this solution, a fixed rod 22 is provided on the top surface of the workbench 1. A visual inspection machine 21 is provided at the end of the fixed rod 22 away from the workbench 1. The visual inspection window of the visual inspection machine 21 faces the top surface of the inspection tray 23.

[0046] Preferably, in order to assist the precise inspection of the vision inspection machine 21 and the feeding component and the precise feeding, a positioning groove is provided on the top surface of the inspection tray 23 for positioning the vision inspection machine 21 and the feeding component.

[0047] The inspection tray 23 has a circular disc-shaped structure, and the outer edge of the inspection tray 23 is concentric with the outer edge of the inspection lamp.

[0048] Preferably, in this embodiment, the vision inspection machine 21 can analyze the uploaded images taken by a high-precision camera, and the inspection lamp can be a high-frequency and high-brightness light source.

[0049] The feeding component is arranged at the edge position of the top surface of the workbench.

[0050] The feeding component includes a feeding group 4 arranged in the feeding direction of the workbench 1, a discharging group 5 arranged in the discharging direction of the workbench 1, and a feeding group 3 arranged between the feeding group 4 and the discharging group 5.

[0051] The feeding group 4, the discharging group 5 and the inspection tray 23 are located on the same plane.

[0052] The feeding group 4 is a feeding conveyor belt 41.

[0053] The discharging group 5 is a discharging conveyor belt 51.

[0054] Preferably, the feeding conveyor belt 41 and the discharging conveyor belt 51 can be replaced with a feeding box and a discharging box.

On the side of the feeding tray 37 away from the mounting strip 33, there are four claw clamps 371 that can be combined into a cylindrical structure. The claw clamps 371 can be closed and expanded. Corresponding to each claw clamp 371, a corresponding micro cylinder (not shown in the figure) is arranged in the feeding tray 37. Since there are several replacement methods here in this embodiment and it is well-known in the prior art, no more explanations are made for the claw clamps 371 here.

[0057] The two feeding trays 37 can save driving actions. One driving back and forth only needs fine adjustment to complete the two actions of discharging and feeding.

[0058] The axial directions of the first feeding guide rail 31 and the second feeding guide rail 32 are perpendicular to each other, and the axial direction of the second feeding guide rail 32 is perpendicular to the axial direction of the mounting strip 33.

In order to accurately hold the rubber ring 6, a vision positioning camera is also provided on the side of the feeding tray 37 close to the rubber ring 6 to assist in the positioning operation.

[0064] Working principle: The first telescopic cylinder 34 drives the second feeding guide rail 32 to move axially along the first feeding guide rail 31, the second telescopic cylinder 35 drives the mounting strip 33 to move in the axial direction of the second feeding guide rail 32, and the third telescopic cylinder 36 drives the feeding tray 37 to move up and down. The combination of the first telescopic cylinder 34, the second telescopic cylinder 35 and the third telescopic cylinder 36 realizes the effect of loading and unloading.

[0065] Working principle: After the feeding is completed, the PLC control circuit drives the servo motor to rotate, and the artificial or vision inspection machine 21 performs quality inspection. After the inspection, the feeding component performs loading and unloading, and the unqualified products are not placed on the discharging conveyor belt 51.

[0066] It should be noted that all the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for the mutually exclusive features and / or steps, can be combined in any way.
