[0088] During specific operation, the empty multi-drop cylinder 1 is placed on the multi-drop cylinder fixing frame 202 of the material truck 2. The material truck 2 with the multi-drop cylinder 1 is manually transported to the center of the positioning guide frame 303 of the material truck positioning mechanism 2. After arriving, through manual work instructions, the material truck positioning mechanism 3 of the multi-drop simple-station automatic feeding device starts to work. The clamping cylinder (preferably JSK model) 304 of the material truck positioning mechanism 3 works to clamp the front end of the material truck 2. At this time, the weighing cylinder 702 of the weighing mechanism 7 drives the weighing slide plate 703 to extend under the material truck positioning rod 206.

At the same time, the auxiliary frame drives the silicon material conveying mechanism 6 to move along with the adjustable feeding table mechanism, ensuring the stable material conveying of both. The adjusting servo motor drives the silicon material conveying mechanism 6 to move, so that the silicon material conveyed by the material conveying roller path (preferably a belt conveyor) is aligned with the guide hopper 505.

[0089] When 80% of the material to be fed is reached (calculated in advance according to the re-feeding cylinder 1), the tilting cylinder 402 of the skip tilting mechanism 4 drives the cylinder rod to retract, driving the feeding rotary fixing frame 302 to drive the skip 2 to return to the vertical position.

[0090] The regulating servo motor drives the polysilicon feeding mechanism 6 to move again, so that the polysilicon conveyed by the material conveying roller path (preferably a belt conveyor) is aligned with the material guiding hopper 505.

[0091] After being filled up, the clamping cylinder 304 of the skip positioning mechanism 3 retracts, and the operator transports the skip 2 to the single crystal area to complete the entire automatic feeding process.
