Embodiment 1

[0026] Such as Figure 1-3 , an integrated sample needle feeding and stirring system, including a fixed seat 10, a stirring motor 1, a driving wheel 2, an eccentric wheel 4 and a sample needle 5; the stirring motor 1 is fixed on the fixed seat 10; the eccentric wheel 4 passes through the first The bearing 11 is installed on the fixed seat 10; the sample needle 5 is installed in the eccentric hole of the eccentric wheel 10 through the second bearing 6; the stirring motor 1 drives the eccentric wheel 4 to rotate through the driving wheel 2.

[0027] Drive wheel 2 is connected with eccentric wheel 4 through belt 3 (or gear) transmission.

[0028] A PCB board 9 with an anti-collision optocoupler 7 is arranged on the fixing seat 10 , and a light blocking sheet 8 is arranged on the top of the sample needle 5 .

[0029] The axis of the eccentric hole deviates from the axis of the eccentric wheel 4 by 0.05-0.2 mm, preferably 0.1 mm. You can also take 0.15mm, 0.13mm, 0.08mm and other...

Abstract

The invention discloses an integrated sample needle loading and stirring system which comprises a fixing seat (10), a stirring motor (1), a driving wheel (2), an eccentric wheel (4) and a sample needle (5), wherein the stirring motor (1) is fixed on the fixing seat (10); the eccentric wheel (4) is arranged on the fixing seat (10) through a first bearing (11); the sample needle (5) is arranged in an eccentric hole of the eccentric wheel (4) through a second bearing (6); the stirring motor (1) drives the eccentric wheel (4) to rotate through the driving wheel (2). The integrated sample needle loading and stirring system is simple and ingenious in structure and has the functions of sample loading, stirring and collision avoidance, and by using the system, equipment can be obviously simplified, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an integrated sample needle adding and stirring system. Background technique [0002] At present, automatic biochemical analysis instruments generally use sample needles to add samples. After adding samples, another stirring needle is used to stir and mix the samples and reagents. In this way, a separate stirring needle mechanism and stirring arm are required to stir and mix the samples. and reagents, the structure is complex and more time-consuming, therefore, it is necessary to design a new type of integrated sample needle feeding and stirring system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an integrated sample needle feeding and stirring system. The integrated sample needle feeding and stirring system has a simple and ingenious structure, has both sample feeding and stirring functions, and can significantly improve work efficiency. [0004] The technical...
