Card feeding mechanism for multi-project survey meter and card feeding method thereof

Abstract

The invention discloses a card feeding mechanism for multi-project survey meter and card feeding method thereof. The card feeding mechanism includes a turntable; along the radial direction of the turntable are equipped with a number of card loading tongues that hold reagent, at one end of the card loading tongue is a socket that extends to the edge of the turntable; a turntable-driving device that connects with the turntable and drives the turntable to rotate around an axis; at least two deposit boxes, each deposit box is placed at the periphery of the turntable along the peripheral direction; the outlet of each deposit box can align with the socket of a card loading tongue; a card feeding device, is located at the periphery of the turntable, the feeding device includes a card-dialing part that can approach the socket along the radial direction of the turntable or moving away from the socket; a swinging device, that connects with aforementioned feeding device and drives the card feeding device to rotate around the axis to arrive at different deposit locations; the rotating axes of the turntable and the card feeding device coincide. The present invention can reduce large amount of redundant structures and designs, thereby saving the costs and enabling the overall structure of the multi-project survey meter to be more compact. The present invention can be applied to fluorescence detection.

Description

technical field [0001] The invention relates to a fluorescence detector, in particular to a card feeding mechanism and a card feeding method for a multi-item detector. Background technique [0002] CN 105548132A discloses a fluorescence detector. A plurality of card slots are arranged on a fan-shaped plate along the circumferential direction, and each card slot can be equipped with a reagent card storage box. A push structure is provided at the bottom of each reagent card storage box, and the push structure pushes the reagent card at the bottom of the corresponding reagent card storage box to move toward the reagent card fixing part (carrying tab). [0003] The pushing mechanism (card feeding mechanism) of this reagent card needs to be positioned multiple times during the installation process of the fan-shaped plate, and the installation error is relatively large; and in the subsequent debugging, it is necessary to continuously fine-tune the turntable and the card feeding me...

Problems solved by technology

[0003] The pushing mechanism (card feeding mechanism) of this reagent card needs to be positioned multiple times during the installation process of the fan-shaped plate, and the installation error is relatively large; and in the subsequent debugging, it is necessary to continuously fine-tune the turntable and the card feeding mechanism to meet the use requirements. This increases the difficulty of debugging and affects the performance of the whole machine; and the design of multiple sets of driving structures also makes the structure of the detector complex, which is not conducive to saving costs and simplifying the structure
