Abstract

The invention provides a high-speed high-accuracy multi-axis PCB (Printed Circuit Board) numerical control drilling machine, which comprises a servo driving system, a multi-axis controlled mechanical transmission system, a motor device, a coupling, a position feedback module and a motion controller, wherein the mechanical transmission system is connected with the servo driving system through the coupling and the motor device in sequence; the position feedback module is connected with the mechanical transmission system and the servo driving system; the servo driving system is used for generating a driving signal by using a PID (Proportion Integration Differentiation) control algorithm according to a received control signal and a received feedback signal to drive the motor device; then the mechanical transmission system is driven to move stably by the motor device through the coupling; and the motion controller is built in a computer for controlling and coordinating the motion of each component in the mechanical transmission system. Thus, shock can be reduced during movement and drilling of the drilling machine, and the entire drilling machine can be quickly, accurately and stably controlled.

Description

technical field [0001] The invention relates to a numerical control drilling machine, in particular to a high-speed, high-precision multi-axis PCB numerical control drilling machine and a control method thereof. Background technique [0002] The positioning accuracy of the CNC system is an important index to measure the performance of the CNC machine tool, which directly affects the machining accuracy of the CNC machine tool. Today, as high-speed machining is increasingly becoming the mainstream, the positioning time of the servo system has gradually become a very important performance indicator. However, in most cases, rapidity and accuracy are a pair of contradictory issues that require a compromise. There are many factors that affect the positioning performance of the servo system, among which the control algorithm adopted by the system and the acceleration and deceleration process are particularly significant. In general, the control process of the servo system can be ...
