device and method for positioning of funktionselementen and / or containers in the field of labormanipulators using two light beams kreuzender

摘要

A laboratory robotic manipulating arm assembly works above a horizontal field that is monitored by two photoelectric barriers (9, 9'), each with a light source (10, 10') and light detector (11, 11'). The light beams (12, 12') travel in directions deviating from the X and Y axes. The robotic assembly (1) positions tools (2) or sample (5) containers (3) in a laboratory analysis assembly (4) that has an essentially flat work bench (6) of dimensions X by Y. The robotic arm (7) moves in the X and Y planes and positions tools (2) operating in the Z-plane. The bench (6) has a zone (8) monitored by two photoelectric barriers (9, 9'), each with a light source (10, 10') and light detector (11, 11'). The light beams (12, 12') travel in directions deviating from the X and Y axes. The beams intersect at an angle of 90 and extend at an angle of 45[deg] through the X and Y planes. The assembly has a computer (13) that correlates the X/Y/Z position signals. An independent claim is included for a process for manipulation of liquid sample containers.
