In a preferred embodiment of the present invention, as shown in fig. 2 to 4, the cup receiving mechanism 20 includes: the cup holder comprises a first cup bearing seat 21, a drive plate 22 arranged on the first cup bearing seat 21 and a first motor 23 for driving the drive plate 22 to rotate; the first cup bearing seat 21 is provided with a first sliding groove 211 for bearing the reaction cup 10, the flange 12 is used for contacting with the outer edge of the opening of the first sliding groove 211 so that the first cup bearing seat 21 supports the reaction cup 10, and the drive plate 22 is used for driving the reaction cup 10 to slide along the first sliding groove 211.

Specifically, the cross section of the first cup bearing base 21 is arc-shaped, and the cross section of the first slide groove 211 is also arc-shaped. The dial plate 22 is circular, a plurality of first notches 221 are arranged on the dial plate 22 along the circumferential direction, the size of the reaction cup 10 is smaller than that of the first notches 221, and the reaction cup 10 can fall into the first sliding groove 211 from the first notches 221. The longitudinal section of the first chute 211 is rectangular, the length of the rectangle is greater than the height of the reaction cup 10, and the width of the rectangle is greater than d and less than a, so that after the reaction cup 10 falls into the first chute 211, the lower surface of the reaction cup 10 does not contact the bottom of the first chute 211, the lower surface of the flange 12 contacts the outer edge of the opening of the first chute 211, further, a chamfer 212 is arranged at the outer edge of the opening of the first chute 211, and due to the existence of the chamfer 212, the reaction cup 10 is exactly located at the middle position of the first chute 211 in the receiving and conveying process, so that the reaction cup can accurately enter the cup conveying mechanism 30.

Furthermore, a positioning code disc 24 is arranged on the dial plate 22, a first positioning optical coupler 25 is arranged above the positioning code disc 24, and the positioning code disc 24 is tubular and vertically arranged on the dial plate 22. The side wall of the tubular positioning code disc 24 is provided with a plurality of second gaps 241, the second gaps 241 correspond to the first gaps 221 one by one, when one of the first gaps 221 is located at the cup receiving position 60, the second gap 241 corresponding to the first gap 221 is just located at the first positioning optical coupler 25, when the first positioning optical coupler 25 detects the second gap 241, the first motor 23 is controlled to stop, at the moment, the first gap 221 corresponding to the second gap 241 is located at the cup receiving position 60, so that the cup is convenient to receive, after the reaction cup 10 falls into the first sliding groove 211 from the first gap 221, the reaction cup slides to the first end along the first sliding groove 211 under the shifting of the dial 22.

If the first detector 26 detects that the cup receiving position 60 has a reaction cup 10, the first motor 23 is started to rotate the dial 22, so that the reaction cup 10 is shifted from one end of the first sliding groove 211 to the other end, and the first motor 23 is continuously rotated, so that the reaction cup 10 enters the first end.

More specifically, the dial 22 may advance one cup position every time it rotates during dialing, that is, the first positioning optical coupler 25 stops every time it detects one second notch 241. Alternatively, the reaction cup 10 at the cup receiving portion 60 may be directly moved to the first end, i.e. rotated only once.

Taking the reaction cup 10 as an example of being moved forward by one cup position, when the second pair of forks 32 holds the foremost reaction cup 10 and moves forward by one cup position, the foremost reaction cup 10 is located above the cup falling channel 412, and the reaction cup 10 falls out of the cup falling channel 412 under the action of gravity.

The second cup bearing seat 41 is provided with a temperature detection device 42 for detecting the temperature of the reaction cup 10 in the second chute 411, and when the temperature of the reaction cup 10 exceeds a first preset value, the heating device 50 is stopped; when the temperature of the reaction cup 10 is lower than a second predetermined value, the heating means 50 is activated. Of course, a second detector 43b and a third detector 43a may be further disposed at two ends of the second cup holder 41, the second detector 43b corresponds to the first end (i.e. one end of the second chute 411), the third detector 43a corresponds to a cup position adjacent to the cup dropping channel 412, and the second detector 43b and the third detector 43a are respectively used for detecting whether there is a reaction cup 10 at a corresponding position in the second chute 411.

The invention also provides a preferable embodiment of the reaction cup 10 transmission method based on the reaction cup 10 transmission device, which comprises the following steps:

the reaction cup 10 conveying method based on the reaction cup 10 conveying device provided by the embodiment of the invention comprises the following steps:

step S100, the cup receiving mechanism 20 sequentially receives and delivers the plurality of reaction cups 10 at the cup receiving position 60 to the first end of the cup delivering mechanism 30.

Specifically, in the initial state, the dial 22 is engaged by the positioning code wheel 24 and the first positioning optical coupler 25, and the first motor 23 is activated to align the first notch 221 of the dial 22 with the cup 60. The cup receiving portion 60 has a plurality of reaction cups 10, and when the reaction cups 10 fall into the first sliding groove 211 from the first notch 221 of the dial 22, the flange 12 of the reaction cup 10 rests on the outer edge of the opening of the first sliding groove 211.

When the first detector 26 detects that the reaction cup 10 falls into the first chute 211, the first motor 23 is started, the dial 22 is rotated, and the reaction cup 10 is conveyed to the cup receiving mechanism 20. Specifically, since the first sliding groove 211 communicates with the second sliding groove 411, the cuvette 10 slides from the first sliding groove 211 into (one end of) the second sliding groove 411.

Step S200, the cup feeding mechanism 30 arranges a plurality of reaction cups 10 at the first end of the cup feeding mechanism 30 in sequence and transmits them to the second end of the cup feeding mechanism 30 under the guiding action of the guiding mechanism 40.

Specifically, in the initial state, the first pair of shifting forks 31 is in the tightened state, the second pair of shifting forks 32 is also in the loosened state, and is located at a side close to the first end (that is, the second pair of shifting forks 32 has not been displaced forward), and at this time, the second pair of shifting forks 32 is in the loosened state, the reaction cup 10 sliding into the second chute 411 from the first chute 211 can enter the first end, that is, the reaction cup 10 is located between two second shifting forks, and since the second pair of shifting forks 32 has one more cup position than the first pair of shifting forks 31, the reaction cup 10 is not located between two first shifting forks.

First, when the second detector 43b detects that there is a reaction cup 10 at one end of the second chute 411, the reaction cup 10 in the cup feeding mechanism 30 is now displaced forward by one cup position. When the second detector 43b detects that the first end has the reaction cup 10, the heating device 50 is activated to preheat the reaction cup 10 (of course, the heating device 50 may be activated when the apparatus is turned on, or a switch button of the heating device 50 may be provided). Meanwhile, the second motor 332 is started, the first driving pulley 332b drives the first driven pulley 332a to rotate through the first synchronous belt 332c, as shown in fig. 8, the first driving pulley 332b and the first driven pulley 332a rotate counterclockwise, the front half section 332c1 translates leftward, and the outer right guide plate 336b and the inner left guide plate 335a move leftward along the front guide shaft 3341; the right half translates to the right and the outer left guide plate 336a and the inner right guide plate 335b move to the right along the rear guide shaft 3342, i.e. the first pair of forks 31 are disengaged and the second pair of forks 32 are tightened against the cuvette 10. Of course, the left and right guide blocks 344a and 344b are drawn toward each other along the third guide shaft 343. When the second pair of forks 32 holds the cuvette 10, i.e. the first optocoupler blade 347 is just shifted into the second positioning optocoupler 3311, the second motor 332 is stopped.

Next, when the third motor 341 is turned on, the second driving pulley 341b drives the second driven pulley 341a to rotate through the second timing belt 341c, as shown in fig. 6, the second driving pulley 341b and the second driven pulley 341a rotate counterclockwise, the second timing belt 341c drives the dragging plate 342 to move forward, and certainly, the dragging plate translates forward under the guiding action of the sixth guiding shaft 346, and meanwhile, the left guiding shaft 345a translates forward under the guiding action of the first guiding shaft hole, and the right guiding shaft 345b translates forward under the guiding action of the second guiding shaft hole. Of course, the second pair of forks 32 holding the reaction cup 10 also translates forward by one cup position, and when the second pair of forks 32 translates forward by one cup position, that is, the second optocoupler lock 348 just shifts into the third positioning optocoupler 3312, the third motor 341 is stopped.

Again, the second pair of forks 32 releases the reaction cuvette 10 and the first pair of forks 31 holds the reaction cuvette 10. Specifically, the second motor 332 is activated to rotate in reverse (as shown in fig. 8, the first driver 332b and the first follower 332a rotate clockwise), the front half 332c1 translates rightward, and the outer right guide plate 336b and the inner left guide plate 335a move rightward along the front guide shaft 3341; the right half is translated to the left, and the outer left guide plate 336a and the inner right guide plate 335b are moved to the left along the rear guide shaft 3342, that is, the first pair of forks 31 tighten the reaction cup 10, and the second pair of forks 32 loosen the reaction cup 10. Of course, the left and right guide blocks 344a and 344b are separated from each other along the third guide axis 343. When the first pair of forks 31 hold the cuvette 10, the second motor 332 is stopped. When second motor 332 is rotated in the opposite direction, the opto-coupler can be positioned, and the opto-coupler can also be controlled by time, as long as the time of forward rotation and reverse rotation of second motor 332 is ensured to be consistent.

Finally, the second pair of forks 32 is retracted by one cup position, and the third motor 341 is started to rotate in reverse (as shown in fig. 6, the second driving pulley 341b and the second driven pulley 341a rotate clockwise), the second timing belt 341c drives the dragging plate 342 to move backward, certainly, to translate backward under the guiding action of the sixth guiding axle 346, and meanwhile, the left guiding axle 345a translates backward under the guiding action of the first guiding axle hole, and the right guiding axle 345b translates backward under the guiding action of the second guiding axle hole. Of course, the second pair of forks 32 also moves backward one cup position while holding the reaction cup 10, and the third motor 341 is stopped when the second pair of forks 32 moves backward one cup position. When the third motor 341 rotates reversely, the optocoupler can be positioned and can also be controlled by time, as long as the forward rotation time and the reverse rotation time of the third motor 341 are consistent.

The above circulation is carried out, so that the reaction cups 10 are sequentially arranged in the two chutes to be buffered and fully preheated in the forward conveying process. If the third detector 43a detects a reaction cup 10 indicating that the reaction cup 10 buffered in the second chute 411 is full, and if the reaction cup 10 is to be buffered continuously, the reaction cup 10 is dropped out of the cup dropping channel 412, and then the second pair of forks 32 is activated to forward the reaction cup 10, so that the reaction cup 10 is located above the cup dropping channel 412 and dropped down from the cup dropping channel 412.

In summary, the present invention provides a cuvette conveying apparatus and a method thereof, wherein the cuvette conveying apparatus includes: the cup receiving mechanism, the cup feeding mechanism arranged on the side surface of the cup receiving mechanism and the guide mechanism arranged below the cup feeding mechanism; the cup receiving mechanism is used for sequentially receiving and conveying a plurality of reaction cups at the cup receiving position to a first end of the cup conveying mechanism, the cup conveying mechanism is used for sequentially arranging and conveying a plurality of reaction cups at the first end to a second end of the cup conveying mechanism, and the guide mechanism is used for guiding the conveying of the reaction cups.
