Description

A kind of galvanometer motor motion planning method shortening idle stroke positioning time
Technical field
The present invention relates to galvanometer mechanism kinematic planning field, particularly relate to a kind of galvanometer electricity shortening idle stroke positioning time Machine motion planning method.
Background technology
In field of laser processing such as laser markings, galvanometer motor is a kind of common driver part.Galvanometer motor is a kind of special Different oscillating motor, can only perform deflection action.In field of laser processing, galvanometer sheet is fixed on the axle of galvanometer motor, passes through The swing of galvanometer motor realizes the adjustment of optical path direction, and realizes Laser Processing.Owing to, in laser processing procedure, laser adds , often there are some interruption parts that need not Laser Processing in work hot spot path not necessarily overall situation continuous path.Above-mentioned not The discontinuities needing Laser Processing belongs to the idle stroke of laser process equipment.Reduce the time consumed in the motion of above-mentioned idle stroke Play an important role for improving the work efficiency of laser process equipment.Due to Laser Processing idle stroke section in, intermediary movements section Motion conditions on not impact such as Laser Processing precision etc., only follow-up is just swashed by the motion positions precision of the end of idle stroke There is impact in the light course of processing.Therefore, should use to meet minimizing of end positioning accuracy request in above-mentioned idle stroke section total The motion planning model of body positioning time.
Owing to when high speed jerk swings, the galvanometer sheet of little quality is susceptible to shake, the shake of above-mentioned galvanometer sheet can be at light Cause the shake that laser beam on work surface is bigger under the enlarge-effect effect of road, and reduce the residual jitter in above-mentioned position fixing process and need Expend certain galvanometer sheet residual oscillation die-away time.Therefore, how to shake in preventing fast idle point position motor process The general location time reducing galvanometer sheet while the eyeglass excessive residual oscillation of generation becomes of raising Laser Processing efficiency Key issue.
Move due to the idle stroke of galvanometer sheet and belong to typical some position motion, the most all can use S type motion planning curve Motion planning as galvanometer motor.But owing to classical S type motion planning curve is merely by considering motion song The geometric smoothness of line carries out mechanism kinematic planning and designing, does not take into full account the execution unit during mechanism kinematic There is elastic vibration problem, motion needs certain residual oscillation will be caused could to meet required precision, not die-away time The stationarity of motion and minimizing of general location time can be taken into account.
Patent 201310460878.9 proposes a kind of high-speed mechanism and reduces the S type curve movement planning side of residual oscillation Method, by increasing by one section of section die-away time considering residual oscillation impact in conventional S type curve movement planing method, and builds Vertical accordingly with the Optimized model of the minimum target of section die-away time motion planning time+described.During decay described in patent Between section be mechanism with high speed motion after motion planning end time for ensureing that residual oscillation amplitude is less than position error institute allowable The time quantum needed.Above-mentioned die-away time section by abs (s-s*)+abs (v) < ε, (wherein s, s*, v, ε are respectively moving displacement, phase Hope displacement, movement velocity, position error allowable) obtain.Patent 201310460878.9 is based on traditional S type curve movement The Optimized model of planning contains the residual oscillation die-away time of above-mentioned acquisition, obtains revised integrated motion plan optimization Model.
Patent 201410255068.4 proposes a kind of asymmetric fluctuating acceleration based on dominant frequency energy time domain Optimal Distribution rule The method of drawing, utilizes Nonlinear FEM Simulation analysis to obtain the location of the motion under parametrization asymmetrical movement function drive Residual oscillation response course, and (wherein s, s*, v, ε are respectively moving displacement, expectation position to utilize abs (s-s*)+abs (v) < ε Shifting, movement velocity, position error allowable) judgment criterion carrys out movement executing mechanism residual oscillation and meets the remnants needed for required precision Vibrate die-away time.Residual oscillation amplitude is necessarily less than by patent 201410255068.4 by introducing in optimizing and analyzing model The analysis constraint of position error allowable obtains comprehensive optimal motion planning function parameter.
The integrated motion plan optimization algorithm that patent 201310460878.9 and patent 201410255068.4 are provided is equal Can be used for meeting positioning precision and minimizing the optimal motion planning of the requirements such as general location time needed for obtaining galvanometer mechanism Parameter.The core point of above-mentioned patent is all the judgement to residual oscillation amount die-away time meeting positioning accuracy request.Upper Stating in patent, the acquisition used meets the location allowable employed in the judgment criterion used by motion positioning accuracy request Precision ε does not all have direct physical significance, broadly falls into a kind of approximation relative indicatrix relevant to true sprocket bit shift error allowable. Owing to positioning precision ε allowable in above-mentioned patent is only a kind of relative indicatrix, and in actual complex operating mode same accuracy The ε used by motion required is not necessarily the same, the ε in judgment criterion used by the most above-mentioned patent and true position error allowable There is not a clear and definite functional relationship, this will cause the final motion planning optimum results of above-mentioned patent not necessarily Join the optimal motion planning of true positioning accuracy request.
