Rotation disc type low temperature accessing integral device

Abstract

Disclosed is a rotation disc type low temperature accessing integral device. The rotation disc type low temperature accessing integral device includes a storing tank, storing discs, a driving mechanism, multiple electromagnetic clutches, multiple driving gears, a driving motor, a sample transfer mechanism, a mechanical arm, a conveying belt, a driving motor, and a controlling device, wherein the storing tank includes a tank body and a cover body; one side of the cover body is provided with an accessing hole and a tank plug; the storing discs are stacked up and down through a rotation shaft; the upper end surface of each storing disc is provided with multiple frozen storage box storing slots and an accessing slot hole; and the outer edge of each storing disc is provided with transmission teeth; the driving mechanism includes a driving shaft; the driving shaft is vertically arranged on one sides of the storing discs of the interior of the tank body of the storing tank and the upper end of the driving shaft stretches out of the cover body; the multiple electromagnetic clutches are arranged on the driving shaft and correspond to the storing discs one by one. The multiple driving gearsare separately arranged on the outside of the electromagnetic clutches in a sleeving mode and mesh with the storing discs. The driving motor is arranged on the cover body and an output shaft of the driving motor is connected with the upper end of the driving shaft. The sample transfer mechanism includes a shield body; the shield body is arranged on the upper end of the tank body of the storing tank; and one side of the shield body is provided with a through hole for in and out of a transfer tin. The mechanical arm is arranged in the shield body. One side of the conveying belt stretches into the shield body from the shield body through hole. a driving mechanism driving motor, a conveying belt driving motor and the mechanical arm are separately and electrically connected with the controllingdevice.

Description

technical field [0001] The invention belongs to the field of biological low-temperature sample storage and retrieval, and in particular relates to a turntable-type low-temperature storage and retrieval integrated device. Background technique [0002] The deep cryogenic biological sample bank is an important basic equipment for research in the fields of medicine and biology. The low temperature storage of liquid nitrogen can keep biological tissues such as blood, stem cells and immune cells alive for a long time. [0003] At present, the liquid nitrogen storage tank is a manual structure. When selecting the cryopreservation tube, the operator needs to open the tank cover, reach into the tank and take out the entire cryopreservation plate before picking out a single cryopreservation tube. In addition, it is also necessary to take out the entire cryopreservation plate and store it in a single cryopreservation tube. This way of access exposes the entire cryopreservation plate to...
