Description
Technical Field
The application belongs to the technical field of in vitro diagnostic instruments, and particularly relates to a sample rack pushing mechanism with a thrust detection function.
Background
Generally, the sample to be detected can be loaded in the test tube, and many test tubes are fixed in the sample frame, and the sample frame is in the sample management unit, will carry the sample frame of sample test tube to taking the sample position by the sample management unit, and automatic taking a sample in the test tube by the diagnostic test instrument carries out the analysis that detects. In the sample management unit, there is a very important mechanism, the sample rack transport mechanism. The sample rack conveying mechanism is mainly divided into the following two types according to the structural principle:
1) A belt conveying mechanism;
2) A push plate pushing mechanism;
belt conveying: the sample rack is placed on the conveying belt, and the friction force between the belt and the sample rack serves as driving force to convey the sample piece to a specified position along the guide mechanism. This mechanism has one significant disadvantage: when the sample rack is blocked and the conveying resistance of the sample rack is greater than the friction force provided by the conveying belt, the sample rack and the conveying belt slide relatively to each other, so that the sample rack cannot be conveyed to a specified position; and when the situation occurs in the continuous loading of the sample racks, because the sample racks still exist in front of the conveying queue, the sample racks with faults can not be accurately detected in real time, and even the abnormality can not be found until the diagnostic instrument is stopped.
Push plate conveying mechanism: the push plate conveying mechanism is characterized in that a push plate is arranged behind the sample frame in the conveying direction, and the sample frame is pushed to be pushed to the designated position along the guide mechanism through the movement of the push plate. The mechanism has the advantage that the problem that the clamping stagnation of the sample rack of the belt conveying mechanism cannot be detected in time can be better solved.
But the push plate conveying mechanism still has a more general problem at present: and when the loaded batch of sample racks are not detected completely, the sample racks to be detected cannot be newly added. Namely: continuous loading of the sample rack cannot be achieved.
The main reasons for this problem are: when the previous batch of sample racks to be detected is not processed, the sample racks exist at the push designated position. At this time, if the sample rack push plate pushes the newly added sample rack to the designated position along the guide mechanism, whether the newly added sample rack is pushed in place cannot be accurately detected, and the sample rack push plate cannot accurately know the pushing destination of the currently added sample rack.
