[0043] See also Figures 1 to 8 As shown, the automatic reaction cup feeding device according to the present application is schematically shown, which is mainly used in immunoassay analyzers such as flow fluorescence and chemiluminescence to automatically supply reaction cups.

[0044] The automatic cuvette loading device provided according to the embodiment of the present application includes a conveying mechanism 8100, a hopper 8200, a feeding track 8300 and a separation turntable mechanism 8400. The hopper 8200 is used to accommodate and store the cuvettes and supply the cuvettes to the conveying mechanism 8100. The conveying mechanism 8100 is used to convey the cuvettes one by one to the feeding track 8300. The feeding track 8300 is located between the conveying mechanism 8100 and the separation turntable mechanism 8400. The cuvettes in the feeding track 8300 slide onto the separation turntable mechanism 8400 in sequence. The separation turntable mechanism 8400 is used to separate and arrange the cuvettes so that the corresponding cuvette grabbing device can grab them.

[0045] The conveying mechanism 8100 includes a conveying chain 8110, on which a plurality of receiving slots 8120 are sequentially arranged along the length direction thereof, each receiving slot 8120 is used to receive a reaction cup, and the hopper 8200 is provided with a receiving chamber 8210 for receiving the reaction cup and a discharge port 8220 communicating with the receiving chamber 8210, and the reaction cup in the receiving chamber 8210 enters the receiving slot 8120 through the discharge port 8220, and the conveying chain 8110 sequentially conveys the reaction cups in each receiving slot 8120 to the unloading track 8300. The separation turntable mechanism 8400 is provided with a calibration element 8410, which is used to cooperate with the corresponding reaction cup grabbing device for position calibration.

[0046] The automatic cuvette loading device of the present application is installed at the corresponding position of the immunoassay analyzer, and the separation turntable mechanism 8400 corresponds to the corresponding cuvette grabbing device. A certain number of cuvettes are stored in the accommodating chamber 8210 of the hopper 8200. The cuvettes in the accommodating chamber 8210 enter the receiving slots 8120 of the conveying chain 8110 through the discharge port 8220. The conveying chain 8110 sequentially transports the cuvettes in each receiving slot 8120 to the unloading track 8300. The cuvettes in the unloading track 8300 slide onto the separation turntable mechanism 8400 in turn. The separation turntable mechanism 8400 then separates and arranges the cuvettes, thereby realizing the automatic loading and supply of the cuvettes. When the corresponding cuvette grabbing device grabs the cuvette on the separation turntable mechanism 8400, the cuvette grabbing device first cooperates with the calibration element 8410 on the separation turntable mechanism 8400 to perform position calibration, and then grabs the cuvette.

[0047] Therefore, the automatic reaction cup loading device of the present application has a simple structure and performs position calibration through the calibration element 8410, so that the reaction cup grasping device can grasp the reaction cup more accurately and quickly, with high efficiency, high stability and reliability, and can be better applied to immunoassay analyzers such as flow fluorescence and chemiluminescence.

[0048] In some embodiments, the separation turntable mechanism 8400 includes a fixed seat 8420, a separation turntable 8430 and a first driving member 8440. The fixed seat 8420 is provided with an opening 8421 for receiving a reaction cup, the opening 8421 is connected to the outlet of the unloading track 8300, the calibration element 8410 is provided on the fixed seat 8420, the separation turntable 8430 is sleeved in the fixed seat 8420, and the separation turntable 8430 is provided with a plurality of separation grooves 8431 at intervals along its circumference, the first driving member 8440 is connected to the separation turntable 8430, and the first driving member 8440 drives the separation turntable 8430 to rotate, so that each separation groove 8431 corresponds to the opening 8421 in sequence.

[0049] That is, the first driving member 8440 drives the separation turntable 8430 to rotate, so that the empty separation slot 8431 corresponds to the opening 8421, and the reaction cup in the unloading track 8300 passes through the opening 8421 and enters the separation slot 8431, and then the first driving member 8440 drives the separation turntable 8430 to continue to rotate, and the reaction cup in the separation slot 8431 rotates one station with the separation turntable 8430, and the next empty separation slot 8431 corresponds to the opening 8421, and this operation is repeated, thereby realizing the separation and arrangement of the reaction cups. In this way, the reaction cups are ensured to be stably separated and arranged, with high stability and reliability.

[0050] In some embodiments, the calibration element 8410 is made of a conductive metal material, and a circular calibration hole 8411 is provided on the top of the calibration element 8410. When the corresponding cuvette grabbing device grabs the cuvette on the separation turntable 8430, the probe or other sensing element on the cuvette grabbing device is first inserted into the circular calibration hole 8411 of the calibration element 8410 for position calibration. After the position is calibrated, the cuvette grabbing device grabs the cuvette. Thus, the structure is simple, and it is convenient to grab the cuvette more accurately and efficiently.

[0051] The top of the fixing seat 8420 is also provided with a placement hole 8422 that matches the calibration element 8410, and the top of the calibration element 8410 is higher than the top of the placement hole 8422. As a result, not only the structure is more compact and stable, but also the fixing seat 8420 can be prevented from interfering with the calibration, and the operation is more convenient, safer and more reliable.

[0052] In some embodiments, the first driving member 8440 is a motor disposed below the fixing seat 8420, such as a stepping motor, a servo motor, etc., and the output shaft of the motor faces upward and is connected to the separation turntable 8430. Thus, the operation is more convenient, safer and more reliable.

[0053] A bracket 8450 may also be provided at the bottom of the fixed seat 8420, the first driving member 8440 is mounted on the bracket 8450, a driving shaft extending below the fixed seat 8420 is provided at the bottom of the separation rotary disc 8430, the output shaft of the first driving member 8440 is connected to the driving shaft through a coupling 8460, and a avoidance interval 8451 corresponding to the coupling 8460 is provided on the bracket 8450, and the driving shaft is not shown in the drawings. As a result, the structure is more compact and stable, the operation is more convenient, and the separation rotary disc 8430 can be ensured to rotate better.

[0054] Those skilled in the art will appreciate that the first drive member 8440 may also drive the separation turntable 8430 to rotate via a transmission mechanism such as a synchronous belt mechanism, a transmission chain mechanism or a gear mechanism. The first drive member 8440 may also use other suitable power elements such as a rotary cylinder and an electric slip ring.

[0055] In some embodiments, the conveyor chain 8110 is driven by the second driving member 8130, and the conveyor chain 8110, the second driving member 8130 and the hopper 8200 are installed on the support frame 8140. For example, the support frame 8140 is provided with a driving wheel and a driven wheel that match the conveyor chain 8110, the second driving member 8130 is connected to the driving wheel, the second driving member 8130 drives the driving wheel to rotate, and the driving wheel matches the driven wheel, so that the conveyor chain 8110 is transmitted, thereby realizing the conveyor chain 8110 to transport the reaction cup. As a result, the structure is more stable and the operation is more convenient.

[0056] In some embodiments, the support frame 8140 and the unloading track 8300 are arranged on the fixing frame 8500, and the unloading track 8300 is connected to the separation turntable mechanism 8400 through the connecting plate 8310. Thus, the operation is more convenient, more stable and reliable.

[0057] In some embodiments, Figure 7 , 8 As shown, the conveying chain 8110 includes a plurality of first partitions 8150 and a plurality of second partitions 8160, and the plurality of first partitions 8150 and the plurality of second partitions 8160 are staggered and spaced along the length extension direction of the conveying chain 8110, and a receiving groove 8120 is formed between adjacent first partitions 8150 and second partitions 8160, and a height of the first partition 8150 protruding relative to the bottom wall of the receiving groove 8120 is not equal to a height of the second partition 8160 protruding relative to the bottom wall of the receiving groove 8120.

[0058] It should be noted that the angle between the length extension direction of the receiving groove 8120 and the length extension direction of the conveying chain 8110 can be an acute angle or a right angle.

[0059] That is to say, there is a height difference between the first partition 8150 and the second partition 8160 that form the receiving groove 8120. When the reaction cup falls into the receiving groove 8120, the reaction cup is deflected, which not only reduces the interference resistance encountered by the reaction cup in the process of entering the receiving groove 8120, but also facilitates the reaction cup to fall into the receiving groove 8120 better, thereby improving the loading efficiency.

[0060] In some embodiments, Figures 4 to 6 As shown, the material unloading track 8300 includes a material receiving guide channel 8320 and a slideway 8330. The material receiving guide channel 8320 corresponds to the output end of the conveyor chain 8110, and the reaction cup in the receiving groove 8120 is output to the material receiving guide channel 8320. The slideway 8330 is inclined, one end of the slideway 8330 faces upward and cooperates with the material receiving guide channel 8320, and the other end of the slideway 8330 cooperates with the separation turntable mechanism 8400. The width of the slideway 8330 is greater than the outer diameter of the reaction cup and smaller than the outer diameter of the convex edge of the reaction cup.

[0061] It should be noted that the convex edge of the reaction cup is located at one end close to the cup mouth, the conveyor chain 8110 is usually arranged at an angle, the conveyor chain 8110 conveys the reaction cup upward, the output end of the conveyor chain 8110 is located at the top thereof, the material receiving guide channel 8320 is located below the output end of the conveyor chain 8110, and the material receiving guide channel 8320 is arranged roughly in the vertical direction.

[0062] When the reaction cup on the conveyor chain 8110 is transported to the position corresponding to the material receiving guide channel 8320, the reaction cup falls from the receiving groove 8120 into the material receiving guide channel 8320, and the reaction cup slides along the material receiving guide channel 8320 to the slide 8330. When the convex edge of the reaction cup abuts against the upper edge of the slide 8330, the lower end of the reaction cup swings into the slide 8330 by its own weight, and then the reaction cup slides along the slide 8330 toward the separation turntable mechanism 8400, so that the cup mouth of the reaction cup in the slide 8330 is always facing upward, ensuring that the reaction cup output by the conveyor chain 8110 can better enter the unloading track 8300, with higher stability and reliability.

[0063] In some embodiments, the unloading track 8300 further includes a detection switch 8340, which is used to detect the reaction cup passing through the slide 8330. The detection switch 8340 can be a photoelectric sensor, a reflection sensor, etc. The detection switch 8340 is usually set in the slide 8330. In other words, the detection switch 8340 can detect whether there is a reaction cup passing through the slide 8330, and feedback a signal to the separation turntable mechanism 8400, so as to ensure that the separation turntable mechanism 8400 can operate better, safer and more reliable.

[0064] In addition, a sensor for detecting whether there is a reaction cup in the separation tank 8431 can also be provided on the separation turntable 8430. This makes it safer and more reliable.

[0065] Based on the above-mentioned embodiments of the present disclosure, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0066] The above are only some embodiments of the present application, which are only used to illustrate the technical solution of the present application, rather than to limit it. It should be understood that, for those skilled in the art, without departing from the creative concept of the present application, it is possible to improve or replace it according to the above description, and all these improvements and replacements should belong to the protection scope of the claims attached to the present application. In this case, all details can be replaced by equivalent elements, and the materials, shapes and sizes can also be arbitrary.
