[0032] Working principle: A plurality of valve bodies are poured into the storage tank 59, and the plurality of valve bodies are stacked towards the discharge port through the slope in the storage tank 59, at this time the conveying belt 58 is started, and the valve bodies in the storage tank 59 are conveyed into the inner cavity of the guide groove on the guide frame 56 through the operation of the conveying belt 58; When the valve body is transported to the bottom end of the guide groove, the arc-shaped side wall of the valve body can push the telescopic guide rod 572 to shrink when it is in contact with the trigger piece 573, at which time the signal transmitter 571 receives the signal of extrusion, and the driving device in the support bridge 1 pushes the frame and the air pressure push rod 51 connected to the frame to slide in the support bridge 1, at the same time, the electric telescopic rod 524 drives the distance adjusting plate 523 to adjust the position of the two overturning motors 53, and when corresponding to the positions of the two valve bodies, the air pressure push rod 51 drives the adjusting assembly 52 to move towards the bottom end, so that the two clamping rods 542 are respectively located on the two sides of the valve body. Then, the servo motor 543 drives the two clamping rods 542 to clamp the valve body, because the two arc-shaped notches are arranged on the clamping rod 542, when the pin end of the valve body faces the trigger assembly 57 and is placed in the reverse direction, the height of the pin is higher than the height of the trigger piece 573, so the trigger piece 573 cannot be pushed to extrude the telescopic guide rod 572, and the signal transmitter 571 cannot receive the extrusion signal, so the device can determine that the pin faces the trigger assembly 57, and after clamping the valve body, the device starts the overturning motor 53 to drive the clamped valve body through the power output of the overturning motor 53, and vice versa, when the extrusion signal is received, the pin faces the trigger assembly 57 and the height is lower than the trigger piece 573, the pin can be in contact with the trigger piece 573, or the arc-shaped surface of the valve body is in contact with the trigger piece 573 to push the trigger piece 573. Then, the valve body is transported to the welding device 4 through the rotation of the rotating platform 2 for welding. The above two methods can know that the valve body faces the front and does not need to be turned over. It should be noted that the specific orientation of the valve body can be determined by the extension and contraction of the plurality of spring telescopic rods 55, when the pin of the valve body faces the trigger assembly 57, the two spring telescopic rods 55 close to the trigger assembly 57 are in an elongated state, and vice versa, so the trigger assembly 57 can further accurately determine the orientation of the valve body. And whether the rotating assembly in the placing table 3 rotates to adjust the valve body after placing the valve body is driven through electrical connection. After the above operations are completed, the valve body does not need to be manually turned over and rotated for adjustment during the feeding process, automatic feeding is realized, the labor of workers is reduced, and the processing efficiency is improved.
