The invention discloses a
robot slight collision compensation and
correction system which comprises a standard
laser detection unit and a positioning needle. The standard
laser detection unit is installed and fixed on an operation surface of a target product. The standard
laser detection unit comprises a K
light beam transmitting end, a K
light beam receiving end, an M
light beam transmitting end and an M light beam receiving end; a
robot clamping jaw is installed on a
robot arm through a rotary disc; the
tail end of the positioning needle is fixed on the clamping jaw side of the rotary disc; a probe ball is arranged at the head end of the positioning needle; a geodetic coordinate
system reference coordinate (X0, Y0, Z0) of the central point of the standard
laser detection unit is calibrated in a processor; the processor controls the clamping jaw to move, the current geodetic coordinate
system coordinate value (x1, y1, z1) of the center point of the standard
laser detection unit is obtained, and offset of the movement point position of the robot is corrected. According to the invention, offset of the motion point position of the robot caused by slight collision of the robot can be automatically, quickly and effectively corrected, and the working efficiency and the operation accuracy of the robot are improved.
