[0043] Working process and principle:

[0044] The workers put a plurality of valve plate blanks on the carrier seats 6 in advance, then put the carrier seats 6 into the carrier frames 307 of the loading carrier 306 and stack them, then push the loading carrier 306 to the conveying starting end of the loading conveyor belt 305, then pull out the pull plate 309, so that the carrier seats 6 are automatically dropped onto the loading conveyor belt 305 under the action of gravity, then the loading conveyor belt 305 conveys the carrier seats 6 to the conveying end, and when the carrier seats 6 below the carrier frame 307 are conveyed away by the loading conveyor belt 305, the carrier seats 6 above will continue to be discharged, so that the carrier seats 6 will automatically fall on the loading conveyor belt 305;

[0045] When the carrier seats 6 are conveyed to the loading platform 303 by the loading conveyor belt 305, and the carrier seats 6 are completely in place, the arrival sensor will upload a signal to the control system, and the control system will control the loading conveyor belt 305 to stop conveying, and drive the loading electric push rod 302 to start, drive the carrier seats 6 to rise above the loading port 104 and enter the placing groove of the conveying seat 103;

[0046] Then the annular conveying belt 102 drives the conveying seat 103 and the carrier seat 6 to start conveying on the annular conveying track, when the conveying seat 103 passes through the stamping mechanism 2, the positioning sensor 8 at the stamping mechanism 2 detects that the conveying seat 103 is in place, then the positioning sensor 8 uploads a signal to the control system, and the control system controls the annular conveying belt 102 to stop conveying, and drives the hydraulic cylinder 201 of the stamping mechanism 2 to start pressing, and starts the stamping process;

[0047] When the stamping is completed, the annular conveying belt 102 continues to drive the finished valve plate product after stamping to be conveyed, when the valve plate product is conveyed to the visual detection mechanism 4 along with the annular conveying belt 102, the positioning sensor 8 at the visual detection mechanism 4 detects the in-place condition of the conveying seat 103 and the material loading seat 6, and uploads to the control system, and the control system controls the visual camera to visually detect the valve plate product on the material loading seat 6;

[0048] After the visual detection is completed, the annular conveying belt 102 continues to convey the material loading seat 6, when the material loading seat 6 is conveyed to the discharging port 105, the material loading seat 6 automatically falls from the discharging port 105 and slides along the discharging chute to the discharging conveying belt, and then is automatically conveyed to the end by the discharging conveying belt, and is manually collected or subjected to other processes by other equipment.

[0049] In the present application, by setting the positions of the feeding port 104, the discharging port 105, the stamping mechanism 2 and the visual detection mechanism 4 on the annular conveying belt 102 and the spacing positions of the plurality of conveying seats 103 on the annular conveying belt 102, the feeding port 104, the discharging port 105, the stamping mechanism 2 and the visual detection mechanism 4 are stopped with one material loading seat 6 each time the annular conveying belt 102 is stopped, so that the feeding, discharging, stamping and visual detection processes of the material loading seat 6 can be simultaneously performed when the annular conveying belt 102 is stopped.
