the method comprises the following steps of manually stacking and placing a plurality of material boxes provided with suction nozzles in a storage bin 01, closing a door 015, enabling a conveying jig 03 to be located at a near-end position, opening two clamping arms 051 of an automatic blanking mechanism 05 to enable the lowest material box on the automatic blanking mechanism to fall onto the conveying jig 03, driving the clamping arms to move upwards by a lifting driving device 058, closing the two clamping arms in the moving-upwards process, clamping one material box above the material box on the conveying jig 03 by the two clamping arms 051, lifting all the material boxes above the material box on the material box, separating the material boxes from the material box on the conveying jig 03, and driving the conveying jig 03 to be conveyed to a far-end position from the near-end position by a translation driving mechanism.

At this time, the moving mechanism 04 drives the suction nozzle connecting pipe 02 to the suction nozzle inserted on the material box on the conveying jig 03 at the far end as required, and moves the suction nozzle out of the material box for suction and injection.

When the suction nozzle needs to be replaced, the moving mechanism 04 drives the suction nozzle connecting pipe 02 to insert the suction nozzle 002 thereon into the perforation 063 of the limit plate 061 and to make the top of the suction nozzle 002 be located below the perforation, and then the pipe wall of the suction nozzle to which the suction nozzle connecting pipe is translated is located outside the perforation, preferably to the blanking hole 064. Subsequently, the moving mechanism 04 drives the nozzle connection pipe 02 to ascend to the lower end thereof to move above the limit plate 061, thereby completing the separation of the nozzle from the nozzle connection pipe.

At this time, the moving mechanism 04 drives the nozzle connecting pipe to be inserted into the nozzle on the material box and taken out to the outside for suction and injection.

When no more than 3 suction nozzles remain in the material box 001 on the conveying jig 03 at the far end position; the moving mechanism drives the suction nozzle connecting pipe to be inserted into the suction nozzle or inserted into an insertion hole for inserting the suction nozzle; the translation driving mechanism drives the conveying jig to move from a far end position to a near end position, and the material box falls below the conveying jig under the action of gravity after the conveying jig moves to the outer side of the material box.

When the conveying jig returns to the near-end position, the automatic blanking mechanism automatically drops a material box onto the conveying jig. And the above steps are repeated.

The invention also discloses medical equipment comprising any one of the feeding devices.

The invention has various embodiments, and all technical solutions formed by adopting equivalent transformation or equivalent transformation are within the protection scope of the invention.
