The working process of the invention is as follows:
when the liquid transferring gun is used, the sealing cover is opened, a bagged liquid transferring gun suction head (the suction head is in a cone shape with the outer diameter gradually reduced) is poured into the upper charging barrel from the discharging pipe, the feeding motor and the vibrating motor are started through the controller, the feeding motor drives the driven gear to rotate through the driving gear, the shoveling plate on the wheel disc of the driven gear further rotates, the suction head in the upper charging barrel is thrown and is carried to the high position through the shoveling plate, and the suction head can fall to a feeder, namely the gap between the two upper charging plates. Because the top plate bodies of the two upper material plates are inclined planes with the bottoms relatively close to each other, the minimum distance is smaller than the maximum outer diameter of the suction heads, and the maximum distance is equal to the maximum outer diameter of the suction heads. The suction heads that are left on the feeder end up in two states:
1) The tip is vertically upward, and the big head falls at the maximum gap between the two feeding plates and is aligned with the top surfaces of the tops of the feeding plates;
2) The pointed end faces downwards vertically, and the large end falls at the maximum gap of the two feeding plates and is aligned with the top surfaces of the tops of the feeding plates;
any other state can be changed into the state 2) under the gravity of the gravity center, but the suction head in the state 1) can also fall under the vibration effect of the vibration motor on the feeder; so that only the state 2) feeder remains on the final feeder.
Because the upper material plate is obliquely arranged and the action of the vibrating motor is added, the suction head in the state 2) moves into the arranging bin. Wherein the sucking head of the state that some not normal sucking heads of gesture are not fallen by the vibration or the sucking head of slope rather than vertical state can be hung by the striker block and fall in last feed cylinder. There is of course also the special case that two or even more tips telescope, which if in the vertical position on the feeder, although blocked by the stop block, cannot be hung up, thus affecting the discharge of subsequent tips, and therefore the worker finds for a long time that no tips are subsequently discharged, and needs to manually discharge this disturbance. But because of the dynamic mode of operation of the vibration motor and the shoveling plate, this occurs only with a small probability.
Go up the glassware and carry the suction head to in arranging the storehouse to in getting into the clearance of guide board and guide block thereupon, the controller control air pump bleeds, and the air pump is through first hose to airtight case negative pressure of taking out, because airtight case both ends's intercommunication pipe pressure contact air flue in airtight strip and can't admit air, so final airtight case can manage to find time the airtight space at stopper pole place in will adjusting the chamber through the regulating tube, simultaneously through the external gas of third hose extraction. And the air pumped by the air pump is discharged through the second hose and then blown out through the shunt pipe and the air duct. In the process, the following two actions are also caused to be carried out synchronously:
the suction heads corresponding to the gaps between the guide plates and the guide blocks are blown into the gaps between the adjacent guide blocks and move towards the gaps between the adsorption blocks in the same group, and meanwhile, the third hose provides a suction effect and sucks the suction heads into the gaps between the adsorption blocks in the same group in cooperation with the exhaust of the air duct;
the airtight space at the cock stem place is managed to find time for the chock block drives the cock stem and overcomes the elasticity of spring and removes, and then makes the cock stem promote the clamp plate and remove, and two clamp plates of adsorbing the piece move with organizing, carry out the centre gripping with getting into the suction head in the piece clearance with organizing, and the sucking disc closely adsorbs it behind the contact suction head moreover, prevents that the suction head from dropping.
After the sucker adsorbs the sucker, the airtight box is thoroughly vacuumized, the air pump stops working according to corresponding parameters, no air is discharged from the second hose, and the feeder continues to feed and fill the vacant position where the sucker adsorbs the sucker.
The controller controls the action of the electric push rod, the electric push rod moves the airtight box, the adsorption block and the suction head adsorbed by the adsorption block downwards, and the adsorption block can effectively keep adsorption on the suction head because the air cannot be sucked due to the pressure of the airtight strip when the communicating pipe moves in the air passage;
meanwhile, the controller controls the driving motor to drive the screw rod to rotate, and further drives the sliding seat and the box body on the sliding seat to move on the sliding rail for a certain displacement, so that the grids in the box body correspond to the suction heads adsorbed by the adsorption blocks.
When airtight case removed to its communicating pipe and got into when letting out the gas groove, the sharp-pointed portion of suction head inserted the grid of box body, and external gas got into airtight case from losing the gas groove simultaneously to get into through the regulating tube and adjust the chamber, destroy the negative pressure of sucking disc department and the negative pressure of gag lever post department airtight space respectively, the sucking disc no longer adsorbs the suction head, and the spring drives gag lever post and clamp plate and resets simultaneously, and the suction head falls into in the grid in the box body steadily.
The driving motor drives the airtight box to reset, and the suction heads are sequentially filled into the box body by circulating the actions to finish boxing.

The outer wall of the machine cabin is provided with a controller 6, and the controller 6 is connected with power output parts of the moving structure 5, the feeding mechanism 3, the arranging mechanism and the auxiliary mechanism 7 through electric signals.
The working process of the invention is as follows:
when the liquid transfer gun sucker is used, the sealing cover 305 is opened, the sucker of the bagged liquid transfer gun is poured into the upper charging barrel 301 from the discharging pipe 304 in a cone shape with the outer diameter gradually reduced, the feeding motor 310 and the vibration motor 308 are started through 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 is further rotated, the sucker in the upper charging barrel 301 is thrown and carried to a high position by the shoveling plate 303, and the sucker can fall to the upper charging barrel, namely a gap between the two upper charging plates 306. Because the top plate bodies of the two feeding plates 306 are in the shape of an inclined plane 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 ends up in two states:
1, the pointed end is vertically upward, and the large end is positioned at the maximum gap between the two feeding plates 306 and aligned with the top surfaces of the tops of the feeding plates 306;
2, the pointed end is vertically downward, and the large end is positioned at the maximum gap between the two feeding plates 306 and is aligned with the top surfaces of the tops of the feeding plates 306;
any other state will be changed into the state 2 under the gravity of the gravity center, but the suction head in the state 1 will also fall under the vibration effect brought to the loading device by the vibration motor 308; so that only the state 2 feeder will remain on the final feeder.
Due to the inclined arrangement of the feeding plate 306 and the action of the vibration motor 308, the suction head in the state 2 moves into the sorting bin 2. A state 1 suction head in which some suction heads with irregular postures are not vibrated away or a suction head in an inclined state rather than a vertical state can be hung in the upper charging barrel 301 by the material blocking block 309. There is of course also the special case that two or even more tips telescope, which if in the vertical position on the feeder, although blocked by the blocking block 309, cannot be hung up, thus affecting the discharge of subsequent tips, and therefore the worker finds for a long time that no tips are subsequently discharged, and needs to manually discharge this disturbance. But because of the dynamic manner of operation of the vibration motor 308 and the shoveling plate 303, this occurs only with a small probability.
The suction head is conveyed into the arranging bin 2 by the feeder 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 since the communicating pipe 404 at the two ends of the airtight box 406 is pressed to contact the airtight strip 406 in the air passage 402 and cannot intake air, the airtight box 406 finally pumps the airtight space where the plug rod 409 is located in the adjusting cavity 408 through the adjusting pipe 413, and simultaneously pumps outside air through the third hose 414. And the air pumped by air pump 708 is exhausted through second hose 710 and blown out through shunt 706 and air duct 707. In the process, the following two actions are also caused to be carried out synchronously:
the air exhausted from the air duct 707 blows the suction head corresponding to the gap between the guide plate 705 and the guide block 704 into the gap between the adjacent guide blocks 704 and moves towards the gap between the suction blocks 407 in the same group, and the third hose 414 provides a suction effect to suck the suction head into the gap between the suction blocks 407 in the same group in cooperation with the air exhausted from the air duct 707;
2 the airtight space where the stopper 409 is located is evacuated, so that the stopper piece 410 drives the stopper 409 to move against the elastic force of the spring 412, and further the stopper 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 head entering the gap of the same group of adsorption blocks 407, and the suction disc 415 closely adsorbs the suction head after contacting the suction head, thereby preventing the suction head from falling off.
When the suction cup 415 sucks 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 exhausted, and the feeding device continues to feed and fill the vacant position where the suction head is sucked by the suction cup.
The controller controls the action of the electric push rod 702, the electric push rod 702 moves the suction head adsorbed by the airtight box 406, the adsorption block 407 and the adsorbed block 407 downwards, and the air cannot be sucked because the communicating pipe 404 is always pressed by the airtight strip 405 when moving in the air passage 402, so that the adsorption block 407 can effectively keep adsorbing the suction head;
meanwhile, the controller controls the driving motor 504 to drive the lead screw 503 to rotate, so as to drive the slide base 502 and the box body on the slide base 502 to move on the slide rail 501 for a certain displacement, so that the grid in the box body corresponds to the suction head sucked by the suction block 407.
When the airtight box 406 moves to the position where the communication pipe 404 of the airtight box enters the air release groove 403, the sharp part of the suction head is inserted into the grid of the box body, meanwhile, the outside air enters the airtight box 406 from the air release groove 403 and enters the adjusting cavity 408 through the adjusting pipe 413, the negative pressure at the position of the suction cup 415 and the negative pressure of the airtight space where the plug rod 409 is located are respectively destroyed, the suction cup 415 no longer adsorbs the suction head, meanwhile, 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 by circulating the actions to finish boxing.
It should be noted that, in the above description, the vibration motor 308, the feeding motor 310, the driving motor 504, the electric push rod 702, the controller 6, the air pump 704, and the like are all devices that are mature in application of the prior art, and the specific models may be selected according to actual needs, and the power supply for the vibration motor 308, the feeding motor 310, the driving motor 504, the electric push rod 702, the controller 6, and the air pump 704 may be a built-in power supply or a commercial power supply, and the specific power supply mode is selected according to circumstances, and is not described herein.
