Double-axis synchronous movement control device and method based on feedback of laser displacement sensor

Abstract

The invention discloses a double-axis synchronous movement control device and method based on the feedback of a laser displacement sensor, and the device comprises a double-axis synchronous movement control device body, a displacement detection system, and a control module. The double-axis synchronous movement control device body comprises a first drive mechanism, a second drive mechanism, a first linear movement platform, a second linear movement platform, and an experiment table. The displacement detection system comprises a long-distance laser displacement sensor, a high-precision laser displacement sensor, a reflecting plate, a workbench, a first dividing plate, and a second dividing plate. The control module is connected with the first drive mechanism, the second drive mechanism, the long-distance laser displacement sensor and the high-precision laser displacement sensor. The device enables the movement range of the double-axis synchronous movement control to be enlarged, breaks the limits of a conventional fixed-type detection device, does not need to return to zero, achieves the synchronous movement stably, accurately and quickly, and can quickly recover the synchronization when interference appears and the movement is not synchronous.

Description

technical field [0001] The invention relates to a dual-axis synchronous motion control device and method, in particular to a dual-axis synchronous motion control device and method based on laser displacement sensor feedback, belonging to the field of dual-axis synchronous control. Background technique [0002] In modern manufacturing, people have higher and higher demands for high productivity and low cost. For example, when surface mount machines and CNC machine tools are processing some complex parts or in order to reduce product processing procedures, traditional single-axis motion is often difficult to meet the needs. , the synchronous movement of mechanical axes in production came into being, and because of this, multi-axis systems are widely used in modern industrial production, such as ship lifts and briquettes machines used in the Three Gorges Project, multi-axis roller tables in metallurgical factories, Paper machines, bridge or gantry cranes and various robotic sys...

Problems solved by technology

The high-speed gantry moving key milling machining center is a typical example of synchronous motion. The gantry column is fed longitudinally along the guide rail and can obtain high acceleration characteristics. However, the structure and force of large moving parts such as beams and tool rests are not strictly symmetrical. , plus there are various uncertain disturbances, so the high consistency of the movement of the gantry frame cannot be guaranteed. The mechanical coupling caused by this inconsistency will reduce the degree of synchronous feed, affect the processing quality, and may even make the gantry frame or drive components damaged
