Embodiment 1

[0032] figure 1 Shown is the pipette tip automatic sorting device of the present invention, which includes a tip delivery device, and a tip receiving device arranged on the lower side of the tip delivery device, and the tip delivery device includes a screw 2 and a slide Rod 3, the screw rod 2 is rotatably connected to the frame 1, and the screw rod 2 is connected with a driving device; the slide rod 3 is fixedly connected to the frame 1, and is arranged in parallel with the screw rod 2; There is a gap between the rod 3 and the screw rod 2, the maximum gap between the slide rod 3 and the screw rod 2 is smaller than the maximum diameter of the gun head 4, and greater than the minimum diameter of the gun head 4, on the gap A gun head discharge port 14 corresponding to the position of the gun head 4 receiving device is provided, the gap of the gun head discharge port 14 is greater than the maximum diameter of the gun head 4, and the gun head 4 is transported to the gun The head d...

Embodiment 2

[0038] This embodiment is a more preferred implementation of the present invention, such as Figure 2-3 As shown, in order to avoid the problem that the pipette tips 4 are stacked on the gap of the conveying device, and some pipette tips 4 cannot be hung on the conveying device to maintain a vertical state for sorting, the pipette tips in this embodiment are automatically sorted The device is provided with a multi-layer conveying device along the vertical direction, and the positions of the gaps in the multi-layer conveying device correspond up and down, that is, the gaps of the multi-layer conveying device are parallel to the vertical direction. In this embodiment, two layers of conveying devices are selected, and the conveying device on the lowest layer is provided with a pipette tip discharge port 14 corresponding to the position of the pipette tip receiving device. When a plurality of the gun heads 4 were stacked horizontally and fell to the gap of the upper layer of the c...

Embodiment 3

[0048] This embodiment is basically consistent with Example 2, and the difference is that: the slide bar 3 in this example is a rib, and the slide bar 3 is in line contact with the gun head 4. The edge of the slide rod 3 is opposite to the screw rod 2, and the edge rod is controlled to move toward or away from the screw rod 2 through the adjustment device. The adjustment device is a long hole arranged on the frame 1, one end of the rib passes through the long hole, and the rib can move on the long hole, when the rib moves to the set When the position is fixed, the rib is fixed by a positioning device, and one end of the rib passing through the long hole can be provided with a screw thread, and the positioning device is a fixing seat, and the fixing seat is provided with a connecting part and the rib The thread fits and connects, and the fixed seat is fixed with the frame 1 by screws, so that the positioning device can position the rib, and the rib is not easy to move.

Abstract

The invention discloses an automatic sorting device of a pipette tip, and the device comprises a pipette tip conveying device and a pipette tip receiving device which is arranged on the lower side of the pipette tip conveying device; the pipette tip conveying device comprises a screw rod and a slide rod; the screw rod is rotationally connected to a frame; a driving device is connected onto the screw rod; the slide rod is fixedly connected onto the frame, and is arranged in parallel with the screw rod; a gap is left between the slide rod and the screw rod; the biggest gap between the slide rod and the screw rod is smaller than the maximum diameter of the pipette tip, and is more than the minimum diameter of the pipette tip; a pipette tip outlet which corresponds to the pipette tip receiving device in position is arranged on the gap; and the gap of the pipette tip outlet is more than the maximum diameter of the pipette tip. According to the automatic sorting device of the pipette tip, the technical problems of the prior art that an existing sorting device has low efficiency, a poor effect and poor reliability are solved.

Description

technical field [0001] The invention relates to an auxiliary device for pipette tips, in particular to an automatic sorting device for pipette tips. Background technique [0002] Pipette tips (hereinafter referred to as pipette tips) are often used in biology laboratories, chemical laboratories, medical and other related institutions. In the tip box, a gun tip rack with gun tip holes is placed in the gun tip box, and the gun tips are inserted in each gun tip hole in sequence. Usually, manufacturers of gun tips will pack the gun tips in two different ways: one is full box packaging, that is, the gun tips are placed in an orderly array of gun tips; the other is scattered packaging, that is, hundreds or Thousands or even more gun tips are scattered in one bag. If the user buys a whole box of tips, not only will they have to pay a price that is several times to tens of times higher than that of buying scattered tips, but also due to the large amount of tips used, the empty tip...
