Problems solved by technology

Because the electromagnet moves too fast, it will cause a lot of noise. In addition, the electromagnet can only generate the ideal electromagnetic force when it reaches the specified position, so there are cases where the motor cannot drive the sample to rotate.

Abstract

The invention relates to the technical field of medical instruments and provides a test tube rotating mechanism which comprises a fixing block, a clamping rotating assembly and a cam groove are arranged on the fixing block, the clamping rotating assembly comprises a motor, a driving shaft, a cam, a one-way bearing and a rotating gear, the motor drives the driving shaft to rotate, and the driving shaft drives the rotating gear to rotate. The driving shaft is connected with the cam through a one-way bearing and drives the cam to rotate, a cam flange is arranged on the cam groove, and the circumferential face of the cam makes contact with the cam flange all the time. The driving shaft drives the cam to rotate through the one-way locking characteristic of the one-way bearing, the cam drives the driving shaft to get close to the sample test tube and enables the rotating gear to clamp the sample test tube, then the cam does not rotate along with the driving shaft through the bearing effect of the one-way bearing, and the driving shaft drives the rotating gear to clamp the sample test tube and drive the sample test tube to rotate. A sample test tube can be accurately clamped and driven torotate without an electromagnet.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a test tube rotation mechanism and a test tube rotation code scanning device. Background technique [0002] During blood testing, the test tubes with barcodes are distributed to different instruments for testing related items. The barcodes contain the patient's personal information, and the hospital needs to identify the barcodes on the test tubes. The sample tube with barcode is placed on the test tube rack first, and then enters the automatic sampling platform of the testing instrument. When the user places the sample tube, the direction of the barcode is not necessarily facing the scanner, so the sample tube needs to be rotated so that the barcode is facing the scanner. instrument. [0003] At present, the mechanism for realizing the rotation of the sample test tube on the market usually adopts the mode of electromagnet clamping and motor rotation ...
