Transfer assembly and chip detection device

Abstract

The invention provides a transfer assembly and a chip detection device. The transfer assembly comprises a driving motor, a driving wheel, a driven wheel, a synchronous belt, a slide block, a main absolute position encoder and an auxiliary absolute position encoder, wherein the main absolute position encoder is arranged on the driving motor; the synchronous belt is connected between the driving wheel and the driven wheel; the auxiliary absolute position encoder is connected with the driven wheel; the diameter of the driving wheel is different from the diameter of the driven wheel. The chip detection device mainly comprises a conveying mechanism, a cleaning and liquid replacing mechanism and a testing and reaction device. The transfer assembly and the chip detection device have the advantages that a testing chip is automatically transferred; by utilizing the heat insulation and moisture maintaining functions of the testing and reaction device, the rotary mechanism can pass through the testing and reaction device according to the estimated speed and preset time; the testing chip can be filled with testing liquid and suck the testing liquid through the cleaning and liquid replacing mechanism at site; by utilizing the cleaning and liquid replacing mechanism, the multiple-angle liquid filling, liquid sucking and air-blowing cleaning can be performed, so that the biological chip can be efficiently and accurately detected.

Problems solved by technology

[0003] When dealing with biochips, inspectors need to go through a series of operations: first add the substance to be detected, then add the hybridization solution, then react at the preset temperature, and then need a series of reaction reagents to react, and finally The surface is cleaned by a centrifuge or blowing air, and then can be observed and analyzed by a CCD camera. It can be seen that the equipment involved in the process includes heat preservation equipment, manual sampler, centrifugal equipment, cleaning equipment, air gun and other devices. , the process is highly complex, the efficiency of manual operation is low, and the procedures are cumbersome, and then human errors are prone to occur, which makes the detection fail
