Sample rack transfer device, sample rack loading system and chemiluminescence detector

Abstract

The invention relates to a sample rack transfer device, a sample rack loading system and a chemiluminescence detector. The sample rack transfer device includes a mounting rack, a transfer track, a rocker arm, a reset assembly and a sample rack drive mechanism; the rocker arm is rotatably connected to the mounting rack, and the rocker arm has a first end and a second end respectively located on both sides of the rotation axis; The sample rack driving mechanism includes a guiding structure, a sample rack grabbing component and a sample rack driving assembly; the guiding structure is arranged on the mounting rack parallel to the transfer track; the sample rack grabbing component is used for grabbing or releasing the sample rack; the sample rack driving component is used for When the sample rack grasping assembly is driven to move along the guide structure; when the sample rack grasping assembly moves to the first end of the rocker arm, the sample rack grasping assembly toggles the first end of the rocker arm to make the second end of the rocker arm leave the stopper mechanism; when the sample rack grabbing component leaves the first end of the rocker arm, the reset component drives the second end of the rocker arm to press against the stop mechanism. Therefore, the stopper mechanism can be regulated without arranging a control device.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sample rack transfer device, a sample rack loading system and a chemiluminescence detector. Background technique [0002] The chemiluminescence detector can perform immunological quantitative analysis on patient body fluid samples such as blood samples, so as to detect various symptoms such as cardiovascular disease or anemia. During analysis, the sample tube needs to be supplied to the sample loading arm, and the sample tube is generally loaded in the sample holder. [0003] When the sample holder is stored in the sample holder, the transfer of the sample holder between the sample holder and the sample holder transfer device can generally be done by using a robotic arm that clamps up and down, or it can be done by orbital translation; In the gripping method, the sample holder is likely to fall off and cause damage to the sample; while in the orbital translation method...

Problems solved by technology

[0003] When the sample rack is stored in the sample holder, the transfer of the sample rack between the sample holder and the sample rack transfer device can generally be completed by using the upper and lower gripping mechanical arms, and can also be completed by orbital translation; but using the upper and lower mechanical arms In the way of clamping, the sample rack is easy to fall and cause sample damage; while in the way of rail translation, the sample rack may slip off the track

Although baffles can be used on the track to prevent the sample rack from slipping, it is necessary to configure a control device to regulate the state of the baffles to block or conduct the transmission channel; this will undoubtedly complicate the mechanism of the equipment, and the actions of the various mechanisms are uncoordinated will cause equipment failure
