Automatic rotation test tube bar code recognition device and full-automatic sample treatment system

Abstract

The invention provides an automatic rotation test tube bar code recognition device, and when a first detection device detects that a sample support is in a rotary code scanning position, a controller controls a second driving device to start. And when the second detection device detects that the sample support is in a clamping state, the controller controls the first driving device to start. A first driving device drives a driving wheel module to rotate, the driving wheel module drives a sample support (with a test tube) to rotate, an idle wheel module and a driven idle wheel module passively rotate under the action of friction force of the test tube, and a code scanner carries out bar code recognition on the rotating sample support (with the test tube). In order to ensure the pressing force of friction wheels on the driving wheel module, the idle wheel module and the driven idle wheel module on the sample support, a second driving device is used for controlling the spring pressing force of a spring device, so that the friction wheels are always tightly attached to the sample support when rotating, the sample support is prevented from loosening, and the test tube bar code is accurately read. The invention further provides a full-automatic sample processing system.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an automatic rotating identification test tube barcode device and a fully automatic sample processing system. Background technique [0002] The laboratory assembly line is the centralized management of samples. A single test tube is transported from one point of the laboratory to another along the conveyor belt of the automation system. During the transportation process, the test tube needs to be identified to arrange the test tube to be transported to the next station. After the barcode information on the test tube is recognized, it can pass through the computer program. To manage the test tube accordingly. [0003] Since the barcode is attached to the test tube and the test tube is cylindrical, the direction of the barcode of the test tube is not fixed during the movement on the assembly line, but the position of the scanning code of the scanner is fixed, s...

Problems solved by technology

However, as the sample holder drives the test tube to rotate, the rotating friction wheel will be worn, which will easily lead to inaccurate positioning and code scanning failure.
