It should be noted that in the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein. Accordingly, the scope of the present invention is not limited by the specific embodiments disclosed below.

As shown in fig. 1-6, the utility model provides a pipettor rifle head cartoning ware, including gesture guiding mechanism, the mechanism that drops and control mechanism. The posture adjusting mechanism is used for arranging scattered gun heads in a unified state with the thick end upwards and the thin end downwards, and the dropping mechanism is used for dropping the arranged gun heads and transferring the dropped gun heads to the gun box.

Specifically, the posture adjustment mechanism includes a first division bar 110 and a first barrier 120. The plurality of first separating strips 110 are arranged in parallel, and the distance between every two adjacent first separating strips 110 is smaller than the maximum outer diameter of the gun head and larger than the minimum outer diameter of the gun head. When the scattered gun heads are placed at the top of each first parting strip 110 and shaken, the gun heads are changed into vertical postures with the thick ends upward and the thin ends downward under the action of gravity and interception of the first parting strips 110, and the inclined box filling device can enable the gun heads to be gathered towards the rear ends of the first parting strips 110 along the first parting strips 110.

The front end of each first division bar 110 is fixed on the first baffle 120, and the first baffle 120 plays a role in fixing the first division bars 110 on one hand, and also plays a role in containment on the other hand, so that the gun head is prevented from falling in the oscillation process.

The falling mechanism comprises second separating strips 210 and a second baffle 220, specifically, a plurality of second separating strips 210 are arranged in parallel, the second separating strips 210 extend in the same direction as the first separating strips 110, the distance between adjacent second separating strips 210 is greater than the maximum outer diameter of the gun head, each second separating strip 210 is correspondingly connected to the rear end of each first separating strip 110, and the second separating strips 210 and the first separating strips 110 can approach to and depart from each other along the extending direction of the second separating strips 210 and the first separating strips 110. The number and spacing of the first and

second spacers

110, 210 depends on the corresponding hole locations in the gun case.

When the lance tip moves from the passage between the first spacer bars 110 to the passage between the second spacer bars 210, the lance tip may fall from between the second spacer bars 210 as the distance between adjacent second spacer bars 210 is greater than the maximum outer diameter of the lance tip. At this time, the channels between the second spacers 210 are aligned with a row of holes on the gun case, so that the gun heads can correspondingly drop into the holes on the gun case.

Further, the rear end of each second separating bar 210 is fixed on the second baffle 220, and the second baffle 220 plays a role of enclosure and prevents the gun head from falling off in the operation process.

The control mechanism is used for controlling the second separating strip 210 and the first separating strip 110 to approach and separate from each other along the extending direction of the two.

When the posture of the lance tip needs to be adjusted by oscillation, as shown in fig. 3 and 4, the second partition bar 210 is controlled to approach the first partition bar 110, and the second baffle 220 fixedly connected with the second partition bar 210 is driven to move towards the first partition bar 110, so that the distance between the second baffle 510 and the rear end of the first partition bar 110 is reduced, and the lance tip is prevented from falling from the channel between the second partition bars 210.

When the lance tip with the adjusted posture needs to be transferred into the lance box, as shown in fig. 5 and 6, the second partition bar 210 is controlled to be away from the first partition bar 110, and the second baffle 220 fixedly connected with the second partition bar 210 is also driven to be away from the first partition bar 110, so that the distance between the second baffle 510 and the rear end of the first partition bar 110 is increased, and the lance tip can fall from the channel between the second partition bars 210.

In one of them embodiment, the utility model provides a pipettor rifle head cartoning ware still includes two third baffles 310, and the face of third baffle 310 is parallel with the extending direction of first parting bead 110 and second parting bead 210, and the both sides at first baffle 120 are fixed respectively to the front end of two third baffles 310, and third baffle 310 plays the containment effect, prevents that the rifle head from dropping at the oscillation in-process.

Further, in the preferred embodiment, the control mechanism includes a plunger 410, a return spring 420, and a stop 430. In the oscillation state, the control mechanism can control the second division bar 210 and the second baffle 220 to be in a state of being close to the first division bar 110.

Specifically, as shown in fig. 7, two insertion rods 410 extend in the same direction as the first and second separating bars 110 and 210, the front ends of the two insertion rods 410 are correspondingly fixed to the rear ends of the two third blocking plates 310, and the rear end of each insertion rod 410 freely penetrates through the rear outer side of the second blocking plate 220 and is respectively sleeved with a return spring 420. The two stoppers 430 are fixed to rear ends of the two insertion rods 410, respectively, and limit the return spring 420 to an outer side of the insertion rod 410 between the stoppers 430 and the second shutter 220. When no external force is applied, the second baffle 220 is close to the rear end of the first division bar 110 under the elastic force of the return spring 420, and the lance tip cannot enter between the second division bars 210, so that the operation of oscillating the lance tip can be performed. When second dividing strip 210 or second baffle 220 is pushed, the distance between second baffle 220 and the rear end of first dividing strip 110 is increased, the lance tip can enter between second dividing strips 210 and fall, and the process of moving second baffle 220 forces return spring 420 to compress and deform.

As shown in fig. 8 and 9, in one embodiment, a sliding groove 440 is formed at a rear portion of each first division bar 110, and a front end of each second division bar 210 is slidably inserted into each sliding groove 440. The third baffle 310 is provided with a slide rail 450, the slide rail 450 extends in the same direction as the slide grooves 440, and the slide rail 450 is communicated with the slide grooves 440 arranged on the outermost side.

Further, in order to facilitate the control of the second barrier 510 away from the rear end of the first barrier strip 110 when transferring the lance tip to the lance box, the control mechanism further comprises a push block 460 and a connecting rod 470. The pushing block 460 is disposed outside the sliding groove 440, one end of the connecting rod 470 is connected to the pushing block 460, the other end of the connecting rod 470 passes through the sliding channel 450 and then is connected to the first division bar 110 in the sliding groove 440, and moving the pushing block 460 can drive the first division bar 110 to move in the sliding groove 440. Thus, when the second separating bar 210 and the second baffle 220 need to be controlled to be away from the rear end of the first separating bar 110, the pushing block 460 is pushed to drive the second separating bar 210 to move.
