[0014] The embodiments of the utility model will be described in detail below with reference to the drawings, and the embodiments are implemented on the premise of the technical scheme of the utility model, and the detailed implementation mode and specific operation process are given, but the protection scope of the utility model is not limited to the following embodiments.

[0015] As Figures 1-3 shown, the reaction cup sorting and screening device provided by the utility model comprises a spiral track 2 arranged on a reaction cup feeding vibrating disc 1, and comprises a support table 3, a screening gear 4 and a cup separating piece 5 arranged in sequence from bottom to top.

[0016] In the embodiment, the support table 3, the screening gear 4 and the cup separating piece 5 are all arranged on the top spiral track 2 of the vibrating disc 1. Specifically, the support table 3 is installed at the position close to the outlet of the top spiral track 2, the support table 3 is connected with the spiral track 2 and extends upwardly and obliquely inward, is used for supporting the reaction cup M connected with the screening gear 4, forms resonance with the reaction cup M and prevents the reaction cup M from sliding off the support table.

[0017] The side wall of the vibration disc 1 at the support platform 3 is provided with a groove for installing the screening gear 4 and the cup removing member 5. The screening gear 4 is driven by the motor 6, and the rotation direction is opposite to the conveying direction of the spiral track 2. The periphery of the screening gear 4 is uniformly provided with the teeth for inserting the reaction cup M, and the teeth at the inlet end of the screening gear 4 are axially consistent with the reaction cup M conveyed by the spiral track 2. When the cup mouth of the reaction cup M is opposite to the teeth, the reaction cup M can be inserted on the teeth and rotate with the screening gear 4; otherwise, when the cup mouth of the reaction cup M is away from the teeth, the reaction cup M will fall into the vibration disc 1 under the pushing force of the screening gear 4.

[0018] In order to smoothly separate the reaction cup M from the teeth, the cup removing member 5 is installed above the screening gear 4. It should be noted that, like the support platform 3, the motor 6, the screening gear 4 and the cup removing member 5 are also inclined downward from the center to the edge of the vibration disc.

[0019] The two ends of the cup removing member 5 are provided with the ear plates 51 connected with the top wall of the vibration disc 1. The bottom surface of the inlet section of the cup removing member 5 above the screening gear 4 is higher than the top surface of the reaction cup M inserted on the screening gear 4, and the bottom surface of the outlet section of the cup removing member 5 (i.e. the position of the top pressing surface 52) is lower than the top surface of the reaction cup M inserted on the screening gear 4. The top pressing surface 52 is arranged on the side surface of the cup removing member 5, and the projection of the top pressing surface 52 on the screening gear 4 is an arc structure gradually expanding outward from the center to the teeth of the outlet section. Since the bottom surface at the position of the top pressing surface 52 is lower than the top surface of the reaction cup M, and the cup mouth of the reaction cup M is connected with the top pressing surface 52, the reaction cup M gradually moves to the outer edge of the teeth under the action of the top pressing surface 52 with the rotation of the screening gear 4. When the reaction cup M reaches the position of the support platform 3 at the outlet and is connected with the spiral track 2, the reaction cup M is completely separated from the teeth. At this time, under the resonance of the vibration disc 1, the reaction cup M returns to the spiral track 2 and moves to the outlet track of the vibration disc 1.

[0020] In addition, the bottom surface of the support platform 3 is provided with the interference column 31, and the distance between the bottom surface of the interference column 31 and the adjacent lower spiral track 2 is 1.1-1.8 times the height of a single reaction cup M. For a single reaction cup M, it can pass through smoothly; for two or more reaction cups M stacked together, only the bottommost reaction cup M can pass through the interference column 31, and the others are blocked.

[0021] It can be seen that, under the joint action of the above mechanism, the reaction cups M on the outlet track of the vibration disc 1 are arranged in a single column and in the same direction, thereby ensuring the stable feeding of the fully automatic chemiluminescence immunoassay analyzer and enabling the equipment to operate stably for a long period.

[0022] It should be noted that in the description of the utility model, such as "front", "back", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating the orientation or positional relationship of the terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.
