TEST TUBE GRIPPER, TEST TUBE LABELING UNIT, AND TEST TUBE PREPARING APPARATUS INCLUDING THE SAME

摘要

The present invention relates to a test tube preparation device which is compact, light and more mobile and improve the spatial layout of an installing unit, a transfer unit and a label attaching unit and the constitution of the units. According to an aspect, the invention may comprise a frame in which right and left installing units where a plurality of test tubes are vertically installed are provided on the upper part and at least one guide hole which allows the test tube to move by passing through the hole; a gripper transfer unit transfers the test tubes installed in the right and left installing units to the guide hole; a gripper pinches or separates the test tubes; and a labelling unit attaches a label to the waist of the test tube transferred through the guide hole.

主权项

1. A test tube gripper that grips a test tube of which the lower portion is inserted into a hole of a pallet, separates the test tube from the pallet and transfers the test tube, comprising:
a base plate; a gripper body coupled to the base plate; a finger fixing block for moving up and down with respect to the gripper body; an up-and-down operation unit for moving the finger fixing block up and down; and a finger configured: to be coupled to the finger fixing block; to move up and down cooperating with the finger fixing block; to allow the clampers facing each other to be apart from each other to receive the test tube when moving down; and to allow the clampers facing each other to move close to each other to grip the received test tube when moving up, wherein: the gripper body is rotated in the front-back direction with respect to the base plate by a front-back direction repulsive force of the test tube created during the gripping and separating processes of the test tube; and the finger is rotated in the left-right direction with respect to the finger fixing block by a left-right direction repulsive force of the test tube created during the gripping and separating processes of the test tube.
