Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in FIG. 1, the reaction cup station switching mechanism mainly comprises a first module 1, a second module 2, a bridge 3, a support 4, a driving part 5 and a swing arm 6.

Wherein, first module 1 is gone up to distribute and is put a glass groove 1a, and second module 2 is gone up to distribute and is put a glass groove 2a, and the first outside of putting a glass groove 1a and second and putting a glass groove 2a is all uncovered, and the crane span structure 3 is arranged between first module 1 and second module 2, is equipped with direction passageway 3a on the crane span structure 3. The support 4 is provided with a driving part 5, the driving part 5 is a motor, an output shaft 5a of the motor is connected with a swing arm 6, and the swing arm 6 is positioned above the guide channel 3a.

In this embodiment, the first module 1 is a circular ring structure, and the first cup placing grooves 1a are distributed on the circular ring structure in a circular array. The second module 2 is a disc-shaped structure, and the second cup placing grooves 2a are distributed in the circumferential direction of the disc-shaped structure in an annular array manner. When the reaction cup station switching mechanism is applied to a chemiluminescence immunoassay analyzer, the first module 1 and the second module 2 are rotatably assembled in the analyzer, and the bridge frame 3 and the support 4 are fixedly assembled in the analyzer.

Based on the above implementation structure, the working principle of the reaction cup station switching mechanism is as follows:

referring to fig. 2 and 3, as the first module 1 and the second module 2 rotate, one of the first cup holding grooves 1a faces the right end of the guide channel 3a, and one of the second cup holding grooves 2a faces the left end of the guide channel 3a. At this moment, the reaction cup 8 is placed in the first cup placing groove 1a, the motor drives the swing arm 6 to rotate clockwise, the lower end of the swing arm 6 pushes the reaction cup 8 out of the first cup placing groove 1a, and then the reaction cup enters the second cup placing groove 2a through the guide of the guide channel 3a, so that the reaction cup 8 is transferred from the first module 1 to the second module 2.

In this embodiment, the first module 1 is a reaction module, and the second module 2 is a detection module, that is: the motor drives the swing arm 6 to rotate, so that the reaction cup 8 can be transferred from the reaction module to the detection module. Besides, the first module 1 and the second module 2 can also be other modules for incubation, filling, washing, etc. The first module 1 and the second module 2 can convey reaction cups in a linear motion mode besides conveying the reaction cups in a rotary motion mode.

Further, the swing arm 6 comprises a connecting disc 6a fixedly sleeved with the output shaft 5a, and a cantilever 6b extending radially outwards from the connecting disc 6a, and a hook structure 6c is arranged at the far end of the cantilever 6 b. In the rotating process of the swing arm 6, the hook structure 6c acts on the lower edge of the support ring platform 8a at the upper part of the reaction cup 8, and the reaction cup can be ensured to be smoothly pushed to the second cup placing groove 2a. Referring to fig. 1 again, it can be seen that an avoiding notch 1b is arranged on the inner side of the first cup holding groove 1a, and the width of the avoiding notch 1b is greater than the thickness of the hook structure 6c. So design, can guarantee that crotch structure 6c passes dodges breach 1b, then the lower edge of 8 support ring platforms of reaction cup 8 is acted on successfully for the reaction cup can be by smooth colluding to the second and put cup groove 2a.

As shown in fig. 2, an arc-shaped groove 6a1 is formed in the circumferential edge of the connecting disc 6a, a limit pin 5b is fixedly mounted on the motor, and the limit pin 5b is located in the arc- shaped groove 6a 1. So design, the effect of leaning on of accessible arc wall 6a1 both ends and stop pin 5b retrains swing arm 6's rotation range, has structural design reasonable, the good technical advantage of reliability. Furthermore, a photoelectric sensor 7 which is adaptive to the thickness of the connecting disc 6a is further arranged on the motor and used for judging and counting whether the reaction cup station switching mechanism carries out cup moving operation or not, and the automatic progress of the analyzer is guaranteed.
