Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a sample rack conveying device and a sample distribution platform and applications. Background Art

[0002] Before and after analyzing human body fluid / blood samples, the sample rack needs to be loaded into the channel first, and then transported from the starting position of the channel to the dispatching mechanism through the conveying device, so as to be subsequently identified, temporarily stored, analyzed, recovered, and other operations at various workstations. The sample rack to be analyzed can be an offline sample rack (manually placed in the sample introduction area) or an online sample rack (automated assembly line transportation). A technical solution is required to achieve the simultaneous transportation of online and offline sample racks to meet the requirements of integrated and automated sample distribution. For offline samples, after the sample rack is loaded into the channel, the existing conveying device uses a linear motion mechanism to transport it from the starting point to the end point, and then needs to return to the starting point along the original route and load the next sample rack, and repeat this cycle to complete the transportation of all sample racks; for online samples, the existing conveying device needs to be additionally provided with a track change mechanism.

[0003] In summary, the prior art has the following disadvantages:

[0004] (1) Low transportation efficiency: To ensure that there is no structural interference, all actions in the prior art are serial, and the total execution time is the sum of the execution time of each action. For example, when docking online, the sample rack transmission process is: online sample rack loading-track change-push hand push-push hand reset-online sample rack loading; all actions are serial, and the next sample rack can only be loaded after all previous actions are completed, which is inefficient.

[0005] (2) Structural redundancy: In order to connect the sample racks on the line, the existing technical solution has an additional track change mechanism designed. The mechanism needs to match the corresponding motor, guide rail and control system, which increases the manufacturing cost and maintenance cost. When it is only used for connecting the sample racks under the line, the aforementioned track change mechanism is a redundant structure. The existing technical solution has a low degree of integration and obvious redundancy. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a sample rack conveying device and a sample distribution platform and application. The sample rack conveying device of the present invention is arranged on the sample table, and includes a support platform, a linear drive component, a guide component and a pusher component.

[0040] (3) In order to achieve simultaneous matching of online and offline sample racks, the prior art adds a set of track changing devices (the device includes a motor, a guide rail and other structural parts), and also needs to match the corresponding control unit and control program; while the sample rack conveying device of the present invention uses a special guide mechanism to achieve the avoidance of the sample rack loading position during the reset process of the pusher assembly.

[0041] (4) In the prior art, the conveying mechanisms for the sample loading and sample recovery processes are completely independent mechanisms, which increases the complexity of the structure; however, the sample rack conveying device of the present invention can not only be used to convey newly loaded sample racks, but can also be reused after slight adjustments to the conveying device for sample rack recovery. The reuse of parts effectively reduces the processing, assembly and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
