[0122] Working principle:

[0123] First, the front-end appearance inspection equipment puts the soldering capacitors 200 with no defects in appearance into the tray one by one. When the tray is full of capacitors 200, the belt line in the unloading input belt line mechanism is activated to transport the full tray to the first in-place detection element 12. At this time, the tray blocking mechanism 2 is activated to block the tray at the first in-place detection element 12. When there is no tray at the second in-place detection element 13 and the lifting cylinder 32 in the capacitor tray lifting mechanism 3 is in the lowered position, the tray blocking mechanism 2 will be activated. At this time, the capacitor tray will be transported by the conveyor belt to the second in-place detection element 13. At this time, the capacitor tray lifting mechanism 3 is activated to lift the capacitor tray up. When it is in place, the photoelectric switch 45 in the tray pushing mechanism 4 detects it and the tray The pushing cylinder 42 in the pushing mechanism 4 will be activated to push the pallet into the pallet output belt line mechanism 5. The pallet output belt line mechanism 5 starts to operate and transports the capacitor pallet to the third in-position detection element 53 in the pallet output belt line mechanism 5. At this time, the push rod 62 in the push rod mechanism 6 starts to operate under the drive of the rodless cylinder 61, and pushes the capacitor pallet to the partition 751 corresponding to the material frame 75 in the material receiving mechanism 7. Then, after being pushed into place, the push rod 62 retreats back to its position. The material frame 75 begins to descend to the next partition 751 under the action of the third driving assembly 74 driven by the ball screw 741, waiting for the next capacitor pallet to enter, and goes down in sequence until the material frame 75 is full. Finally, the material frame 75 is output, and a new material frame 75 re-enters to start storing materials. Here, the material frame 75 enters the wire body by manually placing the empty material frame 75 into the lateral entry wire body 77 in the material receiving mechanism 7, and then the lateral entry wire body 77 transports the material frame 75 to the material receiving mechanism 7; the material receiving mechanism 7 drives the material frame 75 to move downward until the material frame 75 is filled and output.
