The working process of the invention is as follows:
when the automatic feeding device is used, the sealing cover is opened, the bagged pipette tip (the pipette tip is in a cone shape with the outer diameter gradually reduced) is poured into the feeding cylinder from the discharging pipe, the feeding motor and the vibrating motor are started by the controller, the feeding motor drives the driven gear to rotate through the driving gear, the shoveling plate on the driven gear wheel disc is further enabled to rotate, the shoveling plate throws the pipette tip in the feeding cylinder to a high position, and the pipette tip can fall to the upper feeder, namely a gap between the two feeding plates. As the top plate bodies of the two feeding plates are in an inclined plane shape with the bottoms relatively close to each other, the minimum distance is smaller than the maximum outer diameter of the suction head, and the maximum distance is equal to the maximum outer diameter of the suction head. The suction head remaining on the feeder eventually assumes two states:
1) The tip is vertical upwards, and the big end falls at the maximum gap of the two feeding plates and is aligned with the top surface of the top of the feeding plates;
2) The tip is vertically downward, and the big end falls at the maximum gap of the two feeding plates and is aligned with the top surface of the top of the feeding plates;
any other state can be changed into a state 2) under the gravity action of the gravity center, but the suction head in the state 1) also falls off under the vibration effect of the vibration motor to the feeder; only the feeder of state 2) will remain on the final feeder.
Due to the inclined arrangement of the feeding plate and the action of the vibrating motor, the suction head in the state 2) moves into the sorting bin. Some of the non-properly oriented tips are not vibrated off or the tips are tipped rather than vertical to be caught by the baffle plate in the upper barrel. There is of course also a special case where two or even more tips are nested, if they are in a vertical position on the feeder, they are blocked by the blocking block, but they cannot be hung up, so that the discharge of the subsequent tips is affected, so that the staff find for a long time that no subsequent tips are discharged, and then need to manually discharge the interference. However, this is only a small probability of occurrence due to the dynamic manner of operation of the vibration motor and the shoe.
The feeding device conveys the suction head into the sorting bin, and then enters a gap between the guide plate and the guide block, the controller controls the air pump to pump air, the air pump pumps negative pressure to the airtight box through the first hose, and as the communicating pipes at two ends of the airtight box are pressed against the airtight strips in the air passage to enable air to be unable to enter, the airtight box finally evacuates the airtight space where the plug rod in the adjusting cavity is located through the adjusting pipe, and meanwhile, the third hose pumps outside air. And the air pumped by the air pump is discharged through the second hose and then blown out through the shunt tube and the air duct. In this process, the following two actions are also caused to be performed synchronously:
the air exhausted by the air duct blows the corresponding suction head in the gap between the guide plate and the guide block into the gap between the adjacent guide blocks and moves towards the gap between the same group of adsorption blocks, and meanwhile, the third hose provides a suction effect and is matched with the exhaust of the air duct to suck the suction head into the gap between the same group of adsorption blocks;
the airtight space where the plug rod is located is evacuated, so that the plug sheet drives the plug rod to overcome the elasticity of the spring to move, and then the plug rod pushes the pressing plate to move, the two pressing plates of the same group of adsorption blocks move to clamp the suction head entering the gap of the same group of adsorption blocks, and the suction cup tightly adsorbs the suction head after contacting the suction head to prevent the suction head from falling.
After the sucker adsorbs the suction head, the airtight box is thoroughly vacuumized, the air pump stops working according to corresponding parameters, the second hose is not discharged with air, and the feeder continues to feed and fills the empty position of the suction head sucked by the sucker.
The controller controls the electric push rod to act, the electric push rod moves the airtight box, the adsorption block and the suction head adsorbed by the adsorption block downwards, and as the communicating pipe is always pressed by the airtight strip to prevent air from entering when moving in the air passage, the adsorption block can effectively keep the adsorption of the suction head;
meanwhile, the controller controls the driving motor to drive the screw rod to rotate, so that the sliding seat and the box body on the sliding seat are driven to move on the sliding rail for a certain displacement, and the grid in the box body corresponds to the suction head adsorbed by the adsorption block.
When the airtight box moves to the position that the communicating pipe of the airtight box enters the air leakage groove, the sharp part of the suction head is inserted into the grid of the box body, meanwhile, external air enters the airtight box from the air leakage groove and enters the adjusting cavity through the adjusting pipe, negative pressure at the suction cup and negative pressure in an airtight space where the plug rod is positioned are respectively destroyed, the suction cup does not adsorb the suction head any more, the spring drives the plug rod and the pressing plate to reset, and the suction head stably falls into the grid in the box body.
The driving motor drives the airtight box to reset, and the suction head is sequentially filled into the box body by circulating the actions, so that boxing is completed.
It should be noted that, in the above description, the vibration motor, the feeding motor, the driving motor, the electric putter, the controller, the air pump, etc. are relatively mature devices in the prior art, the specific model may be selected according to actual needs, and the power supply of the vibration motor, the feeding motor, the driving motor, the electric putter, the controller, and the air pump may be a built-in power supply, or may be a mains supply, and the specific power supply mode may be selected as appropriate, which is not described herein.

The outer wall of the machine cabin is provided with a controller 6, and the controller 6 is electrically connected with the power output parts of the moving structure 5, the feeding mechanism 3, the finishing mechanism and the auxiliary mechanism 7.
The working process of the invention is as follows:
when the invention is used, the cover 305 is opened, the bagged pipette tips (the tips are described below) are poured into the feeding cylinder 301 from the discharging pipe 304 in a cone shape with the outer diameter gradually reduced, the feeding motor 310 and the vibrating motor 308 are started by the controller 6, the feeding motor 310 drives the driven gear 302 to rotate through the driving gear 311, the shoveling plate 303 on the wheel disc of the driven gear 302 further rotates, the shoveling plate 303 throws the tips in the feeding cylinder 301 up and brings the tips to the high position, and the tips can drop to the gap between the two feeding plates 306. Because the top plate bodies of the two feeding plates 306 are in an inclined plane shape with the bottoms relatively close to each other, the minimum distance is smaller than the maximum outer diameter of the suction head, and the maximum distance is equal to the maximum outer diameter of the suction head. The suction head remaining on the feeder eventually assumes two states:
the 1-point is vertically upwards, and the big end falls at the maximum gap between the two feeding plates 306 and is aligned with the top surface of the top of the feeding plates 306;
the 2-point is vertically downward, and the big end falls at the maximum gap between the two feeding plates 306 and is aligned with the top surface of the top of the feeding plates 306;
any other state can be changed into a state 2 under the gravity action of the gravity center, but the suction head in the state 1 can also fall off under the vibration effect of the vibration motor 308 to the feeder; only state 2 feeders will remain on the final feeder.
Due to the inclined arrangement of the loading plate 306, the suction head of state 2 is moved into the sorting bin 2 by the action of the vibration motor 308. State 1 in which some of the non-properly oriented tips are not vibrated out or inclined rather than vertical tips may be caught by the baffle 309 in the upper barrel 301. There is of course also a special case where two or even more tips are nested, if they are in a vertical position on the feeder, which is blocked by the blocking block 309, but there is also a failure to hang up, which can affect the discharge of the subsequent tips, so that the staff can find for a long time that no subsequent tip is discharged, and this interference needs to be manually discharged. However, this is only a small probability of occurrence due to the dynamic manner of operation of the vibration motor 308 and the shoe 303.
The feeder conveys the suction heads into the sorting bin 2 and then enters the gap between the guide plate 705 and the guide block 704, the controller 6 controls the air pump 708 to pump air, the air pump 708 pumps negative pressure to the airtight box 406 through the first hose 709, and the airtight box 406 finally pumps out the airtight space where the plug rod 409 in the adjusting cavity 408 is located through the adjusting pipe 413 and pumps out external air through the third hose 414 because the communicating pipes 404 at two ends of the airtight box 406 press against the airtight strips 406 in the air channel 402 to prevent air from entering. And the air pumped by the air pump 708 is exhausted through the second hose 710 and is further blown out through the shunt 706 and the air duct 707. In this process, the following two actions are also caused to be performed synchronously:
the air exhausted from the air duct 707 blows the corresponding suction heads in the gaps between the guide plate 705 and the guide block 704 into the gaps between the adjacent guide blocks 704 and moves towards the gaps between the same group of suction blocks 407, and meanwhile, the third hose 414 provides a suction effect, and the suction heads are sucked into the gaps between the same group of suction blocks 407 in cooperation with the exhaust of the air duct 707;
the airtight space where the plug rod 409 is located is evacuated, so that the plug piece 410 drives the plug rod 409 to move against the elastic force of the spring 412, and then the plug rod 409 pushes the pressing plate 411 to move, the two pressing plates 411 of the same group of adsorption blocks 407 move to clamp the suction heads entering the gaps of the same group of adsorption blocks 407, and the suction disc 415 tightly adsorbs the suction heads after contacting the suction heads, so that the suction heads are prevented from falling.
After the suction cup 415 adsorbs the suction head, the airtight box is completely vacuumized, the air pump stops working according to the corresponding parameters, the second hose 410 is not discharged again, and the feeder continues to feed and fills the empty position of the suction head sucked by the suction cup.
The controller controls the electric push rod 702 to act, the electric push rod 702 moves the airtight box 406, the adsorption block 407 and the suction head adsorbed by the adsorption block 407 downwards, and the adsorption block 407 can effectively keep adsorbing the suction head because the communicating pipe 404 is always pressed by the airtight strip 405 to prevent air from entering when moving in the air passage 402;
meanwhile, the controller controls the driving motor 504 to drive the screw rod 503 to rotate, so as to drive the sliding seat 502 and the box body on the sliding seat 502 to move on the sliding rail 501 for a certain displacement, so that the grid in the box body corresponds to the suction head adsorbed by the adsorption block 407.
When the airtight box 406 moves to the position that the communicating pipe 404 of the airtight box moves into the air leakage groove 403, the sharp part of the suction head is inserted into the grid of the box body, meanwhile, external air enters the airtight box 406 from the air leakage groove 403 and enters the adjusting cavity 408 through the adjusting pipe 413, the negative pressure at the suction cup 415 and the negative pressure of the airtight space where the plug rod 409 is positioned are respectively destroyed, the suction cup 415 does not adsorb the suction head any more, the spring 412 drives the plug rod 409 and the pressing plate 411 to reset, and the suction head stably falls into the grid in the box body.
The driving motor 504 drives the airtight box 406 to reset, and the suction heads are sequentially filled into the box body to finish boxing.
