Automatic assembling system for laboratory pipette head

Abstract

The invention relates to an automatic assembling system for a laboratory pipette head. The automatic assembling system for the laboratory pipette head comprises a control box, a conveying device, transmission railways, a material collecting device and a collecting device; the control box is used for providing power for the conveying device; the conveying device comprises a first conveying area anda second conveying area; the first conveying area is in smooth abutting joint with the second conveying area; the material collecting device communicates with one end of the first conveying area; thetransmission railways are arranged on the conveying device to limit side-by-side conveying of pipette heads; the collecting device comprises a pipette head box with guide rail grooves, a cover plateand side inserting plates; the pipette head box is placed at the tail end of the second conveying area; the guide rail grooves are railways with chutes and can be in smooth abutting joint with the transmission railways; the cover plate is detachably connected with the pipette head box; the side inserting plates are be inserted and connected through side holes in a side surface of the pipette headbox; and a high-temperature sterilizing box is also arranged on one side of the tail end of the second conveying area. The automatic assembling system for the laboratory pipette head has the advantages of simple structure and high flexibility, can be assembled to use, and can also perform a high-temperature sterilizing operation simultaneously.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical instruments, in particular to an automatic assembly system for laboratory pipette tips. Background technique [0002] Pipette gun is a kind of pipette, which is often used in the laboratory to pipette a small amount or a small amount of liquid. The specifications are different. Pipette guns of different specifications are equipped with different sizes of tips, and the shapes produced by different manufacturers are also slightly different. , but the working principle and operation method are basically the same. [0003] At present, when the laboratory uses a pipette for micro-sampling, it needs to be equipped with a disposable tip of the pipette to absorb the fixed liquid and blow out the sample. However, due to frequent experimental operations, the pipette tips 6 in the tip box are often exhausted quickly and need to be inserted manually, which is very cumbersome and time-consuming. ...

However, due to frequent experimental operations, the pipette tips 6 in the tip box are often exhausted quickly and need to be inserted manually, which is very cumbersome and time-consuming

[0004] Chinese patent document: CN103274078B discloses a sorting device in which pipette tips are installed in the tip box. In the clamping groove of the device, many pipette tips are vertically erected in the clamping groove with the opening facing upwards, and the push plate assemblies located at both ends of the clamping groove arrange all the pipette tips in the clamping groove closely, and the tip placement device Send a row of pipette tips in the clip groove into a row of holes in the tip box, the clip grooves of the push plate assembly are separated, the pipette tips fall into the tip box after leaving the clip groove, and the tips are put back The device returns to the initial state; the transfer device continues to transport the scattered pipette tips to the tip placement device, and then arranges the pipette tips in the next row of wells, and repeats this process until the entire tip box is neatly arranged. On the left and right sides of the pipette tips, this patent document realizes the arrangement of the tips in rows through mechanical reciprocating movement, but the placement process is not continuous, takes a long time, and the tips are prone to inversion, crowding, etc. unexpected situation

A linear suspension track, the linear suspension track includes a linear arrangement channel and support parts located on both sides of the arrangement channel, the pipette tip is suspended on the support part and arranged in a straight line in the arrangement channel; Liquid gun head tooth profile regulator, said pipette tip tooth profile regulator has a comb tooth structure, the roots of the teeth are distributed on a straight line, and the distance between each tooth root is at least greater than that of the pipettes arranged in a straight line on the suspension rail Tip spacing; the pipette tip dispenser and pipette tip automatic assembly machine described in this patent document can realize automatic and fast boxing of tips, and even fast boxing of multiple specifications of tips at the same time; but its structure is complicated, The flexibility is greatly reduced, which is not conducive to the out-of-the-box experiment
