Abstract

The invention discloses a gantry dual-driving system and an error detection method thereof, and belongs to the technical field of automation control. The gantry dual-driving system comprises a cross beam, a driving shaft, a driven shaft, a main shaft, a first mark point and a second mark point, wherein the driving shaft and the driven shaft are parallel to each other, two ends of the cross beam are movably fixed on the main shaft and the driven shaft respectively, the first mark point and the second mark point are located between the driving shaft and the driven shaft, the main shaft is movably mounted on the cross beam, a visual system is arranged on the main shaft, and position information of the first mark point and that of the second mark point are read through the visual system respectively, so as to detect a journey error of the system. By virtue of mechanical characteristics of the dual gantry driving system per se, control complexity is reduced, not only is the characteristic of high measurement precision of the visual system exerted, but also the difficulty in double-side coupling control on the driving shaft and the driven shaft is avoided, and the gantry dual-driving system has a very high practical value.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to a gantry double drive system and an error detection method thereof. Background technique [0002] The gantry dual drive system is a common robot actuator in the automated production industry. It is synchronously driven by dual motors to obtain greater acceleration characteristics. [0003] However, due to the differences in the characteristics of the motors and screw rods at both ends of the gantry, after a period of movement, the above structure is prone to problems such as inconsistent displacement at both ends of the gantry, increased stroke error, and poor machining accuracy. This requires detecting and correcting the error of the gantry dual drive system every time it runs for a period of time to ensure that the machining accuracy of the system meets the requirements. [0004] Therefore, it is necessary to propose a gantry double drive system and its error detect...
