Automatic cup feeding device, cup feeding method thereof and sample analyzer

Abstract

The invention discloses an automatic cup feeding device, a cup feeding method thereof and a sample analyser, the automatic cup feeding device comprises a bin body and a direction adjusting structure, the bin body defines a cup falling bin and a cup containing bin for containing reaction cups, the cup containing bin and the cup falling bin are communicated through a cup screening opening, the reaction cups with preset directions can pass through the cup screening opening, a conveying channel is arranged at the bottom of the cup falling bin, the cup falling bin and the conveying channel are used for limiting the reaction cups falling into the cup falling bin into the conveying channel in the posture that cup openings face upwards, and the direction adjusting structure is connected to the cup containing bin, and is used for adjusting the reaction cups in the cup containing bin to the preset direction. According to the invention, on the basis of controlling the cost, the purpose of uninterrupted and smooth transmission of the reaction cups can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic cup feeding device, a cup feeding method, and a sample analyzer. Background technique [0002] In clinical testing equipment, such as chemiluminescence analyzers, coagulation analyzers, etc., during the testing process, a transfer device is needed to automatically add cuvettes, thereby reducing manual operations and improving the automation of the instrument. The conveying device in the prior art is generally composed of a bin body for temporarily storing cuvettes, a transmission channel connected to the bin body, and a liftable trough-shaped top plate. Combing, so that the cuvette can be hung in the groove of the groove-shaped top plate, and enter the transmission channel through the outlet of the warehouse body along the groove, and then transported to the subsequent station. [0003] When the trough-shaped top plate is moving up and down, it is impossible...

AI Technical Summary

Problems solved by technology

[0003] When the trough-shaped top plate is moving up and down, it is impossible to ensure that all the cuvettes can fall into the trough in their correct orientation. Some cuvettes will appear horizontally or the bottom of the cup will be upward, and the subsequent cuvettes will continue to be transported. This part of the cuvette will be squeezed, so that they will be stuck at the outlet of the chamber body

In order to overcome this jamming phenomenon, two methods are generally adopted in the prior art, one is to stop the machine and manually correct the stuck cuvette, which will cause interruption of cuvette delivery and affect work efficiency; It is to add a deviation correction mechanism at the exit of the warehouse body to realize automatic correction, which can ensure work efficiency to a certain extent, but the added deviation correction mechanism will lead to a significant increase in manufacturing costs
