The processing station 203 between the stations 202 is described by taking the loop transfer of one of the flow plates 200 as an example.

As shown in FIG. 5, in use, the flow plate 200 is first placed at the loading station 201 of the first transfer rail 20, at which time the first rail 211 is in a clamped state and clamps the flow plate 200. The first driving member 212 drives the first conveyor belt 213 to rotate, thereby conveying the flow plate 200 to the processing station 203. Preferably, the stop device 70 can be disposed at the processing station 203, and the stop device 70 is controlled by the controller 60 to stop the flow plate 200 at the processing station 203, so that the operator can complete the load on the flow plate at the processing station.

As shown in FIG. 6, after the processing operation of the processing station 203 of the flow plate 200 is completed, the controller 60 controls the stop device 70 to be released, and the flow plate 200 is transferred to the unloading station 202, and the driving device 420 of the first transposition unit is Under the control of the controller 60, the driving tray 410 abuts against the flow plate 200 and inserts the positioning pin 412 into the corresponding pin hole 209 of the flow plate 200, while the first driving member 212 drives the blanking under the control of the controller 60. The two first rails 211 of the station 202 move back to release the flow plate 200 (at this time, the first rail 211 of the blanking station 202 is in the released state). The tray 410 carries the flow plate 200 and moves downward under the action of the driving device 420 to transfer the flow plate 200 to the second transfer track 30. After the flow plate 200 is transferred to the second transfer rail 30, the first driving member 212 drives the two first guide rails 211 of the lowering station 202 to move toward the clamped state under the control of the controller 60, and the driving device 420 drives the tray 410. Further moving downward to disengage the locating pin 412 from the pin hole 209 to allow the flow plate 200 to slide along the second rail 311 under the action of the second conveyor belt 312.

As shown in FIG. 7, when the flow plate 200 slides to the other end of the second transfer rail 30 and is located below the loading station 201, the first driving member 212 drives the two stages of the loading station 201 under the control of the controller 60. A guide rail 211 is moved back to the released state, and at the same time, the driving device 420 of the second shift unit drives the tray 410 to move up against the flow plate 200 and insert the positioning pin 412 into the flow under the control of the controller 60. Among the pin holes 209 corresponding to the plate 200, the tray 410 carries the flow plate 200 and moves upward by the driving device 420 to transfer the flow plate 200 to the first transfer track 20. After the flow plate 200 is transferred to the first transfer rail 20, the first driving member 212 of the loading station 201 drives the two first guide rails 211 of the loading station 201 to return to the clamped state to be clamped under the control of the controller 60. Tightening the flow plate 200, the drive unit 420 drives the tray 410 to move further downward below the second transfer track 30. As such, the flow plate 200 completes a loop under the action of the flow plate loop mechanism 100.

As can be seen from the above, by using the flow plate loop mechanism 100 to recirculate the flow plate, the number of the flow plates 200 can be effectively reduced, so that the production cost can be better reduced while maintaining the production efficiency.
