Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical devices, and in particular relates to a reaction cup supply and unloading device for an immunoassay analyzer. Background Art
[0002] At present, in vitro diagnosis is one of the most commonly used diagnostic methods in the medical field. According to the detection principle or detection method, in vitro diagnosis is mainly divided into biochemical diagnosis, immunological diagnosis, molecular diagnosis, microbiological diagnosis, urine diagnosis, coagulation diagnosis, blood and flow cytometric diagnosis, etc. Among them, biochemical and immunological diagnosis are the main methods of in vitro diagnosis in my country. These diagnostic methods all use fully automatic or semi-automatic instruments for sample addition, analysis, and give diagnostic reports.
[0003] During the test, a reaction cup is needed to hold the reaction reagent and body fluid sample and mix them. After a period of reaction in a heated and heat-insulating environment, the reaction cup is transported to the detection position and the photon counter performs photoelectric conversion detection.
[0004] Fully automatic immunoassay analyzers usually use disposable cuvettes, which are poured into the cuvette storage tank (hopper) in a disordered manner. For high-speed fully automatic immunoassay analyzers, a cuvette supply device is required that can sort the disordered cuvettes at a high speed and stably and complete the loading action. After the test process is completed, the unloading device needs to recycle the used cuvettes to free up the test position for the next batch of tests, and this cycle repeats.
[0005] The speed of the existing device for sorting reaction cups (hereinafter referred to as the cup sorting speed) is low and cannot meet the application requirements of high-speed equipment. The cup sorting speed is very different when there are more and fewer reaction cups in the hopper. In addition, the stability of the existing device for sorting reaction cups is poor and it is easy to "get the cup stuck". After the "getting stuck" failure occurs, there will often be a lot of noise and manual intervention is required to resume the test. Summary of the invention

[0024] The present invention provides a device for supplying and unloading reaction cups of an immunoassay analyzer, which has the following beneficial effects compared with the prior art:
[0025] The present invention drives the No. 1 driving wheel to rotate by the No. 2 motor, so that the toothed belt moves, and at the same time the No. 1 driving wheel drives the No. 2 driving wheel to rotate synchronously, at this time the No. 2 driving wheel drives the No. 2 driven wheel to rotate through the transmission belt, the rotating shaft of the No. 2 driven wheel drives the rotating swing arm to drive the No. 2 bearing wheel to rotate, the No. 2 bearing wheel pushes the No. 2 slider to perform linear reciprocating motion along the No. 2 linear guide through the pushing groove, the No. 2 slider pushes the linkage adapter block to perform synchronous motion, and at this time the linkage adapter block synchronously pushes the vibration piece push rod and the feeding push block to perform linear reciprocating motion, At this time, the vibration plate push rod pushes the unloading vibration plate to vibrate, and guides the reaction cup on the unloading vibration plate to the loading push block, and the loading push block guides the reaction cup onto the toothed belt. At this time, the reaction cup on the toothed groove on the toothed belt is transported to the feeding port of the righting slide under the action of the toothed belt. At the same time, the No. 3 bearing wheel of the passive vibrator hits the cover nut to make the toothed belt vibrate, thereby causing the reaction cup in the toothed groove to fall into the U-shaped groove provided on the righting slide. Under the action of the U-shaped groove and the gravity of the reaction cup itself, the reaction cup is righted (the cup mouth faces up and the cup bottom faces down) and guided out.
[0026] The No. 3 motor is used to drive the double round belt pulley to rotate, thereby causing the conveyor belt to move. The reaction cup introduced by the cup sorter assembly enters the conveyor belt. If the reaction cup is in the right position, the mouth of the reaction cup is placed on the two conveyor belts and moves under the transportation of the conveyor belts. If the reaction cup introduced by the cup sorter assembly on the conveyor belt is out of position, it will be blocked by the No. 2 elastic line and tilted backwards, and automatically straightened under the action of gravity. At the same time, the reaction cup above the right-position reaction cup will be blocked by the limit block, and will fall back between the two conveyor belts and automatically straighten when the conveyor belt reverses. At the same time, if the reflective photoelectric sensor at the input end is blocked, it indicates that the reaction cup buffer is full, and the cup sorter assembly stops running. If the reflective photoelectric sensor at the output end is not blocked, it indicates that the buffer is insufficient and the cup feeder stops running.
[0027] The No. 4 motor drives the No. 1 gear to rotate, and the No. 1 gear pushes the meshed No. 1 rack to perform linear motion along the length direction of the No. 3 linear guide rail. At this time, the No. 1 rack pushes the reaction cup located at the output end of the transmission component, and pushes the reaction cup into the reaction cup placement position on the rotating reaction disk, while the No. 5 motor drives the No. 2 gear to rotate, and the No. 2 gear pushes the No. 2 rack to slide along the length direction of the No. 3 linear guide rail, pushing the unloading finger to perform linear motion (when the unloading finger is in the initial position, it extends into the reaction disk housing and is located above the reaction cup placement position in the rotating reaction disk), thereby pulling the reaction cup located on the reaction cup placement position of the rotating reaction disk into the cup withdrawal channel opened on the connecting base, and then falling into the cup dropping opening opened on the connecting base. The No. 3 light blocking sheet cooperates with the photoelectric switch to ensure that the reaction cup is pulled into the top of the cup dropping opening opened on the connecting base by the unloading finger, and at the same time, the shooting sensor can detect whether the cup dropping is normal.
[0028] The present invention can drive the No. 1 pulley assembly to move through the No. 1 motor. The pulley in the No. 1 pulley assembly pushes the No. 1 slider to perform linear motion in the vertical direction along the No. 1 linear guide rail through the synchronous belt connecting plate. When the high-position photoelectric sensor detects the obstruction of the No. 1 light-blocking plate, it indicates that the pallet has moved to the high position. If the opposing photoelectric switch is blocked at this time, the No. 1 motor will reciprocate to drive the No. 1 slider to perform reciprocating linear motion, and drive the pallet to move up and down, shake the material out, and guide the reaction cup into the cup sorting assembly. If the opposing photoelectric switch does not detect the obstruction, it is determined that the main hopper is out of material, the pallet drops to the low-position photoelectric sensor, and notifies the user to add a reaction cup.
[0029] The present invention adopts a main and auxiliary hopper continuous supply structure, which solves the problem that the traditional hopper has a small allowable capacity and requires testers to frequently replenish reaction cups. In addition, since the reaction cups are small in size and light in weight, the allowable capacity of the main hopper can be made larger. BRIEF DESCRIPTION OF THE DRAWINGS

When the high-position photoelectric sensor 806 detects the obstruction of the No. 1 light blocking sheet 805, it indicates that the support plate 809 has moved to the high position. If the photoelectric switch 808 is blocked at this time, the No. 1 motor 812 rotates back and forth at this time, prompting the No. 1 slider 803 to perform reciprocating linear motion, prompting the support plate 809 to move up and down, shaking the discharge, and guiding the reaction cup into the auxiliary hopper of the auxiliary hopper frame 701 in the cup sorting assembly 7.

At the same time, the No. 3 bearing wheel of the passive vibrator 718 hits the cap nut 719 to make the toothed belt 708 vibrate, thereby causing the reaction cup in the toothed groove 722 to fall into the U-shaped groove provided on the straightening slide 717. Under the action of the U-shaped groove and the gravity of the reaction cup itself, the reaction cup is straightened (the cup mouth faces up, the cup bottom faces down) and led out to the two conveyor round belts 603 on the conveying assembly 6. If the reaction cup is straight In this case, the mouth of the reaction cup is placed on the two conveyor belts and moves under the conveyance of the conveyor belt 603. If the reaction cup introduced on the conveyor belt 603 through the cup sorter assembly 7 is out of position, it will be blocked by the second elastic line 608 and fall backwards, and automatically straighten under the action of gravity. At the same time, the reaction cup located above the reaction cup in the right position will be blocked by the limit block 606, and will fall back between the two conveyor belts 603 and automatically straighten when the conveyor belt 603 reverses. At the same time, if the reflective photoelectric sensor 604 at the input end is blocked, it indicates that the reaction cup buffer is full. At this time, the cup sorter assembly 7 stops running. If the reflective photoelectric sensor 604 at the output end is not blocked, it indicates that the buffer is insufficient and the cup feeder stops running.The fourth motor 503 drives the first gear 507 to rotate, and the first gear 507 pushes the first rack 508 meshing with it to perform linear motion along the length direction of the third linear guide 505.
