Abstract

The invention provides an original point calibration system applied to automation equipment. The automation equipment comprises a joint base, a joint moving portion, and a motor used for driving the joint moving portion to move. The original point calibration system comprises an encoder, a calibration component, an original point sensor and a controller, wherein the encoder is mounted on the motorand used for recording the position of the joint moving portion; when the joint moving portion moves relative to the joint base until the calibration component is aligned with the original point sensor, the original point sensor outputs a trigger signal; and the controller is connected with the original point sensor and the encoder and used for receiving the trigger signal output by the originalpoint sensor, obtaining an encoder value of the encoder at the very moment when starting receiving the trigger signal, and determining an encoder value corresponding to an original point according tothe obtained encoder value. The system is used for achieving full-automatic original point calibration of the automation equipment including robots and the like, for improving the calibration precision and for reducing errors.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to an origin point calibration system and method. Background technique [0002] In the field of automation technology, before the actual operation of automation equipment such as robots, it is necessary to calibrate the origin, that is, when the positions specified on each joint of the robot are aligned with the origin specified on the base, the initial position value of each joint is determined (that is, the origin position value), so that in the subsequent robot operation process, the initial position value is used as a reference to realize the positioning of each joint position of the robot and ensure the motion accuracy of each joint of the robot. [0003] In the traditional technology, the origin calibration method mainly relies on mechanical tools to achieve the alignment between the specified position on the joint and the origin on the base, and then determine the initial ...
