Embodiment Construction

[0055] combine Figure 1~6 The present invention is further described:

[0056] attached figure 1 It is a schematic diagram of the mechanical structure of the glass cutting machine. In the deep processing of glass, the high precision and high performance of the glass cutting machine are important guarantees for the subsequent glass processing and the quality of the finished product. The glass cutting machine system is mainly composed of a frame, a conveying system, a positioning system, Road cutting system consists of four parts. The cutter path cutting system is a motion mechanism, which consists of a three-axis servo system: the X-axis servo motor drives the beam to move through the synchronous belt mechanism, the Y-axis servo motor drives the cutting knife box through the reducer, and the Z-axis servo motor drives the cutter wheel through the reducer sports. In the glass cutting process, the control system is required to have good dynamic characteristics to meet high-spe...

Abstract

The invention discloses a method for suppressing the mechanical resonance of a cutting machine servo system. After the online mechanical resonance automatic suppression function of a glass cutting machine servo system is started, a speed control loop samples the quadrature-axis current signal of an X-axis servo motor, and when the number of sampling points is equal to a predetermined point number,starts data operation which mainly includes calculation of signal spectrum, storage of spectrum in a reverse order, calculation of spectrum amplitude, and parameter configuration of a notch filter. The system, after automatically configuring the parameters of the notch filter according to the resonant frequency detected online, can suppress mechanical resonance while maintaining high gain and high stiffness control, ensures the spectrum analysis of the quadrature-axis current feedback signal when the servo system resonates, and detects the resonance spectrum characteristics of the system in real time. The adaptive notch filter is designed based on the detection result of the resonance spectrum characteristic and the parameters of the notch filter are automatically set, which suppresses the mechanical resonance of the cutting machine servo system.

Description

technical field [0001] The invention belongs to the field of glass cutting, and particularly designs a method for suppressing mechanical resonance of a servo system of a cutting machine. Background technique [0002] In the deep processing of glass, the high precision and high performance of the glass cutting machine is an important guarantee for the subsequent glass processing and the quality of the finished product. The glass cutting machine system is mainly composed of four parts: frame, conveying system, positioning system and tool path cutting system. Such as figure 1 As shown, the tool path cutting system is a motion mechanism, which is composed of a three-axis servo system: the X-axis servo motor drives the beam to move through the synchronous belt mechanism, the Y-axis servo motor drives the cutter box to move through the reducer, and the Z-axis servo motor drives the movement through the reducer Drive the movement of the cutter wheel. In the glass cutting process...
