Culture dish sorting and collecting mechanism

Technical Field

The invention relates to the field of solution split charging, in particular to a culture dish sorting and collecting mechanism.

Background

Solution split charging is an essential process in drug screening and microbial solutions. In order to obtain good pharmaceutical ingredients and to define the effect of the drug on the microorganism, high-throughput drug and microorganism effect experiments need to be carried out. In the solution split charging working process, the method mainly comprises three steps of culture dish sorting, culture dish split charging and finished product collection.

In the prior art, as the culture dishes are mostly box-shaped, stacking and collecting difficulties of the culture dishes filled with the solution from top to bottom are relatively high, and the culture dishes are generally sorted and collected by manual operation, the working efficiency of the manual operation is obviously relatively low; there is a need for a mechanism that effectively sorts the culture dishes one by one and collects the filled culture dishes one by one.

Disclosure of Invention

The invention aims to provide a culture dish sorting and collecting mechanism, which can clamp culture dishes one by utilizing a clamping assembly, and can collect the culture dishes one by utilizing a collecting stop block with a torsion spring to realize unidirectional rotation, so that the purposes of efficiently sorting the culture dishes one by one and efficiently collecting the culture dishes after the solution is poured one by one are achieved.

The technical aim of the invention is realized by the following technical scheme:

a culture dish sorting and collecting mechanism comprises a machine base, a sorting opening and a collecting opening, wherein the sorting opening and the collecting opening are arranged on the machine base; a lifting assembly for pushing the culture dish to enter and exit the sorting port and the collecting port respectively; a split charging rotary table which is positioned below the sorting opening and the collecting opening and rotates the culture dish below the sorting opening to a position below the collecting opening; the sorting opening is provided with a clamping assembly for elastically clamping the culture dish, and the clamping assembly comprises a power source driven by a pull rope to return to a separation position; the collecting opening is provided with a collecting stop block which is pushed up from bottom to top in a unidirectional way by utilizing the culture dish, and a torsion spring for resetting is connected between the collecting stop block and the machine base.

Through adopting above-mentioned technical scheme, the clamping assembly singly clamps the culture dish, and when the lifting assembly of below risees, the clamping assembly opens under the pulling effect of stay cord, and the culture dish is put to the lifting assembly under the action of gravity to put to the partial shipment carousel position by the lifting assembly, nevertheless along with the transfer of culture dish, the power supply of stay cord is closed, the clamping assembly resets to the clamping position under the elastic action and presss from both sides the culture dish that presss from both sides next, so the culture dish above the letter sorting mouth can stack and place, utilizes the clamping assembly cooperation lifting assembly of this design to realize efficient letter sorting action one by one;

after the culture dish at the sorting opening is filled with the solution, the culture dish at the split charging turntable is driven by the split charging turntable to reach the lower part of the collecting opening, and the culture dish is conveyed to the upper part of the collecting opening by the lifting component.

Preferably, the clamping assembly comprises clamping plates symmetrically arranged at two sides, and the machine base is provided with springs for pushing the clamping plates at two sides to clamp and move in opposite directions.

Through adopting above-mentioned technical scheme, two symmetries of splint set up and make the opening of both sides bigger when splint are opened, so be difficult to receive when the culture dish whereabouts and separate the fender for the culture dish whereabouts more smoothly high-efficient one by one.
