Abstract
Cartesian robots and methods for proper alignment are provided. More specifically, the invention uses reflective spheres and a laser to locate specific points that can then be used to determine correction factors.
Claims27
An alignment correction system comprising
- (a) a base having a surface with one or more target locations, wherein each target location is fitted to receive a light-reflective object and all of the target locations lie substantially in a single base plane;
- (b) one or more light-reflective objects, each positioned at one of the target locations;
- and
- (c) a probe having a light source and a sensor to detect reflected light, the probe being positionable within a probe plane substantially parallel to the base plane and at a distance from the base plane such that the probe can illuminate each target location with a beam of light and the sensor can detect reflected light from any light-reflective object located at such target location.

An alignment correction system comprising
- (a) a Cartesian robotic arm further comprising a probe;
- (b) a base having a surface with one or more target locations, wherein each target location is fitted to receive a light-reflective sphere and all of the target locations lie substantially in a single base plane, and further wherein the robot arm and the base are vertically disposed from one another and occupy substantially parallel planes;
- (c) one or more light-reflective spheres, each positioned at one of the target locations;
- (d) wherein the probe further comprises a laser and a sensor to detect reflected laser light, the probe being positionable within a probe plane substantially parallel to the base plane and at a distance from the base plane such that the probe can illuminate each target location with a beam of laser light and the sensor can detect reflected light from any light-reflective sphere located at such target location.
