technical field

The invention relates to the technical field of conveying equipment for in vitro diagnostic instruments, in particular to a continuous conveying device used for incubating photometry in reaction cups.

Background technique

Most of the in vitro diagnostic equipment such as automatic chemiluminescence immunoassay system, biochemical analyzer, laboratory assembly line, nucleic acid, etc. will involve the cuvette conveying mechanism. Wherein, when performing photometric detection on the content of serum components in the human body, it is necessary to perform constant temperature incubation on the reaction cup containing the serum sample. The volume of the existing incubation plate is limited, and only a small number of reaction cups can be cultured, and the pretreatment operations such as magnetic washing, substrate injection, and mixing before the reaction cups enter the incubation plate, and photometric operations after the incubation are completed. The automatic gripper transfers the cuvette to the target position. Due to the number of operating stations involved, more grippers need to be set up, resulting in a large volume of the entire equipment and high investment. At the same time, the rotation frequency of the cuvette is high, and the cuvette running speed is slow when the gripper is used, resulting in The overall efficiency of photometric detection is low.

Detailed ways

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation modes and specific operation processes, but the protection scope of the present invention is not limited to the following described embodiment.

As shown in Figures 1 and 2, the continuous conveying device for incubating photometry of reaction cups according to the present invention includes a substrate 1 on which a cuvette conveying track 2 is installed; a drive plate 3 is provided above the cuvette conveying track , the drive plate 3 is provided with a plurality of through grooves 4 that intersect the cuvette conveying track, and the through grooves 4 are arranged in sequence along the cuvette conveying direction; in order to realize the cuvette transportation, the present invention also includes a drive plate 3 for making the cuvette 3 A transmission mechanism that moves along the conveying direction of the cuvette.

Specifically, the cuvette conveying track 2 is fixedly installed on the substrate 1 , which can be a spiral, circular or C-shaped track. In this embodiment, a spiral track with a long stroke and a small footprint is selected. Generally, the cuvette conveying track 2 is a single track whose width is adapted to a single cuvette, which can achieve the purpose of continuously conveying a single cuvette. In practical applications, various equipments are arranged around the cuvette conveying track 2 in order to meet the detection requirements.

In this embodiment, the drive plate 3 has a circular structure, covers the entire spiral track, and is connected to the substrate 1 through a rotating shaft 5 located at the center of the spiral cuvette conveying track 2 . The through grooves 4 thereon are uniformly arranged along the radial direction of the drive disk 3 respectively, and the width of each through groove 4 is adapted to a single reaction cup. The cuvette containing the sample is placed in the cuvette conveying track 2 through the through groove 4 . When the drive plate 3 moves, the cuvette moves forward along the cuvette conveying track 2 . Since the drive plate 3 is provided with a plurality of through grooves 4, there are multiple through grooves 4 forming intersections with the cuvette conveying track 2, and multiple cuvettes can be placed at the same time, and the samples in them can be tested in sequence.

In this embodiment, the drive plate 3 needs to rotate around the center, and the transmission mechanism connected to it includes a rotating shaft 5 arranged perpendicular to the base plate 1 , the rotating shaft 5 has a first end and a second end, and the first end is fixedly connected to the base plate 1 , The second end is rotatably connected to the center of the drive plate through a ball bearing; the outer ring gear 6 is sleeved on the periphery of the drive plate 3, or the drive plate 3 is directly processed into a gear shape, and a stepping motor 7 is installed on the outside of the drive plate 3. The driving wheel 8, the above-mentioned driving wheel 8 and the outer ring gear 6 are meshed and connected. When the stepping motor 7 is started, the driving wheel 8 drives the outer ring gear 6 and the driving disc 3 to rotate.

When working, put the cuvette at the beginning of the cuvette conveying track 2. After the stepper motor 7 is started, the drive plate 3 rotates. During this process, the cuvette conveying track 2 imposes constraints on the cuvette in the diameter direction of the plate. The through groove 4 of the drive disk 3 imposes constraints on the cuvette in the tangential direction of the disk. Under the joint constraint of the drive disk 3 and the cuvette conveying track 2 , the cuvette will move along the cuvette conveying track 2 from the spiral inner circle to the outer circle in a clockwise direction. Since a heating plate is installed at the bottom of the substrate 1, after a period of incubation, the cuvette reaches the photometer around the track for photometric analysis, and then the cuvette continues to follow the drive plate 3 to continue to rotate until it reaches the end of the track and discarded bit to complete the entire incubation photometric cycle.

It should be noted that, in the description of the present invention, the orientations or positions indicated such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc. The terminology of the relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation , so it should not be construed as a limitation of the present invention.
