Problems solved by technology

At present, in the existing medical automation or semi-automation equipment, the transfer of cuvettes is realized by lifting and rotating two independent transport mechanisms, which takes up a lot of space, and the lifting and rotating transport mechanisms need to work in coordination, and the corresponding control circuits are relatively It is more complicated; in addition, there is also a transport mechanism that can lift and rotate at the same time. The rotating mechanism is connected to the lifting mechanism, and the rotating mechanism is connected to the manipulator for grabbing the cuvette. Then drive the manipulator to move up and down. After long-term operation, the rotating mechanism is easily damaged, which increases maintenance costs

Abstract

The invention provides a reaction cup lifting and rotating device. The lifting and rotating device comprises a lifting and rotating device body connected with a manipulator body, the lifting and rotating device body comprises a lifting mechanism, a rotating mechanism and a spline connecting assembly, one end of a spline shaft of the spline connecting assembly is connected with the lifting mechanism, the other end is used for being connected with the manipulator body, and the rotating mechanism is connected with a rotating piece of the spline connecting assembly; and the lifting mechanism drives the shaft to do reciprocating motion in the rotating piece, the rotating mechanism drives the rotating piece to rotate, then the shaft is driven to rotate so as to drive the manipulator body to do lifting or rotating motion, and transportation of a reaction cup is achieved. The invention further provides a reaction cup transfer mechanism. The spline connecting assembly is cooperated with the lifting mechanism and the rotating mechanism to achieve lifting or rotating motion, the lifting motion and the rotating motion are separately and independently performed, during the lifting motion, the rotating mechanism is kept still, a depreciation speed of the rotating mechanism is reduced, maintenance cost is reduced, and an occupied space is small.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cuvette lifting and rotating device and a transfer mechanism. Background technique [0002] In the medical field, it is essential to detect blood, body fluids, etc. These blood, body fluids, etc. are usually collected and placed in cuvettes, and then further operations such as dosing, separating, diluting, and testing are performed. [0003] The above-mentioned liquid preparation, liquid separation, dilution, detection and other operations are generally carried out by automatic or semi-automatic equipment. When the equipment is working, it is necessary to transfer the cuvettes in different working areas. In order to grab and transfer cuvettes to other places, the manipulator usually involves lifting and rotating movements. At present, in the existing medical automation or semi-automation equipment, the transfer of cuvettes is realized by lifting and rotating two indep...
