Rotating shaft calibration method and device for dispensing equipment

Abstract

The invention, which relates to the technical field of dispensing devices, discloses a rotating shaft calibration method and device for dispensing equipment. The calibration method comprises the following steps: mounting a detection head on a Z axis of five-axis dispensing equipment; fixing calibration balls to a rotating platform A and a rotating platform C, enabling the distance between the center of each calibration ball and the upper surface of a rotary table to be equal to the distance between the axis of the axis A of the rotating platform A and the upper surface of the rotating platform, and measuring a secondary coordinate expression of the center of each calibration ball under a new coordinate system through the detection head; setting the A axis of the rotating platform A as a calibration axis, measuring a first position deviation value formula of the ball center coordinate of the calibration ball in the X, Y and Z directions by using the detection head under the condition that the A axis of a swing axis is located at different swing angles and the like. According to the application, the five-axis linkage dispensing equipment can be calibrated for realizing the RTCP function, and the calibration process is high in precision and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of glue dispensing devices, in particular to a method for calibrating a rotation axis of glue dispensing equipment and a device thereof. Background technique [0002] At present, the calibration technology of the rotation axis of the five-axis linkage dispensing equipment mainly adopts the electronic measurement method. This special electronic measurement method requires special measurement equipment. Although this special measurement equipment meets the accuracy requirements, it is expensive and expensive. The operation is cumbersome, and the requirements for technical personnel are high, which is not convenient for widespread application. The other is the manual calibration method. Although the cost of this method is low, its accuracy is also low, and the entire calibration process is cumbersome and poor in standardization. therefore. Need a kind of new technical method badly to solve the above problems....
