Test tube size information identification gripper device

Abstract

The invention discloses a gripper device for identifying size information of a test tube. The gripper device comprises a bracket; the two symmetrically-arranged gripper pieces are movably arranged relative to the support, and open grooves used for clamping test tubes are formed in the opposite sides of the gripper pieces; a main body of the driving device is fixed relative to the support, and the driving device drives the gripper pieces to be close to or away from each other; and the position sensing mechanism is used for detecting the distance between the two gripper sheets. According to the test tube size information identification gripper device provided by the embodiment of the invention, the gripping and size information judgment and identification of different test tubes can be realized, the operation of manual judgment and identification is effectively avoided, the subsequent classification operation of the test tubes is facilitated, and the labor intensity is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of test tube detection equipment, in particular to a gripper device for identifying test tube size information. Background technique [0002] At present, the thickness and length of test tubes used in hospital sample test tubes are different according to different testing items. During manual operation, the length, thickness and other information of the test tubes used can be distinguished with the naked eye, and the test tube samples are not easy to be confused. However, test tubes of different sizes on the assembly line body will bring difficulty in identifying the equipment, and the assembly line needs to identify the information of the test tubes used. At the same time, the conventional test tube clamping device has the problem of uncertain clamping force, and the clamping force of different pipe diameters is quite different, and the large diameter test tube is easy to be clamped. crack Or the barcode p...

However, test tubes of different sizes on the assembly line will bring difficulty in identifying the equipment, and the assembly line needs to identify the information of the test tubes used

At the same time, the conventional test tube clamping device has the problem of uncertain clamping force, and the clamping force of different pipe diameters is quite different, and the large diameter test tube is easy to be clamped. crack Or the barcode paper of the clamped test tube, the problem that the small diameter test tube is not clamped tightly

[0003]In the assembly line process, the test tubes of different sizes on the assembly line body can only be identified by manual operation, and then classified, which will inevitably increase labor intensity
