(1) automatic tube loading machine of blood collection test tube mainly places pet and glass test tube into the tube mould automatically, so as to achieve subsequent automatic production; (2) easy to operate, low failure rate, high production efficiency; (3) adopt human-interface control, with high positioning accuracy; (4) load the test tubes at different heights, and the height adjustment is convenient, i.E. Replacing with corresponding tube mould; (5) cause zero harm to the test tube, automatically detect reversing tube and no tube, and it will automatically alarm when such defects are detected
