Description
Technical field
The present invention relates to a kind of straight line laser technology, the automatic graticule technology of especially a kind of laser, specifically a kind ofThe method of laser level light Self-regulation track.
Background technology
As everyone knows, laser level is a kind of novel optical, mechanical and electronic integration instrument, and it adopts 635nm laser mostlyDiode can project visible red horizontal linear and vertical straight line on metope, utilizes the automatic makeup of instrument internalRepay level (or vertical) position that the manual horizontalization of device or plate level can keep laser projection line. Be mainly used in interior decoration,Erection of doors and windows, pipe installation, tunnel piercing, hang in the construction such as vertical line and quality inspection and project supervision. New pattern laser is thrown lineInstrument is different from conventional calibration instrument in principle, and its required precision is also higher than traditional level, so its actual production and useLight precision regulating method in process and device have caused the concern of more and more Chinese scholars.
Laser level mainly needs the index of calibration to comprise one or the horizontal horizontal accuracy of 1-2 bar, 1-4 barThe orthogonal precision of the horizontal orthogonal precision of vertical line and 1-2 bar, 1-4 bar vertical line, the linearity of laser rays, lower to an essenceThe auto-compensation precision of degree and instrument etc.
Existing laser level is in the time producing, and light control method is mainly that the method for light regulating is: adopt by artificialSet up horizontal reference with spirit level at indoor wall, adopt plumb bob messenger wire as plumb datum, settle instrument apart from metope 3-5m place.Measure respectively the Parallel errors between horizontal laser light horizontal line, vertical line and datum line, according to the data of measuring, manually carry out light regulatingPosition, until reach needed precision. This kind of method can fine solution laser level light regulate problem, but also haveA little drawbacks: when 1) level level is compared, it is highly not easy to adjust, and the bad control of light gradient; 2) light regulatesProcess comparatively loaded down with trivial details, need for a long time; 3) workman's labour intensity is large, and technical ability requires high.
Existing laser level light control method is mainly manual adjustment, and the loaded down with trivial details and adjustment mechanism of adjusting process not onlyDegree of regulation is not high, is not suitable for the automatic adjusting of light. As application number is 200820162697.2, name is called " a kind of semiconductorLaser instrument level fast tuning mechanism " Chinese patent, its structure by pendulum body, laser socket, make laser socket produce upper,The parts such as the adjustment mechanism of lower swing or left and right swing form, by two displacement adjustment screw rods set on operation pendulum body andTwo groups of angle adjustment screw rods, can make laser socket carry out upper and lower pendulum in the inclination installing hole of pendulum body and horizontal installing holeMove or left and right swing. Its a fly in the ointment is that screw rod used is more, is not suitable for the automatic adjusting of light, and the tune of lightJoint precision is not high. And for example application number is 201020671836.1, name is called the Chinese patent of " laser level debugging seat ", its bagDraw together main part, be inserted at least partly the debugging portion of main part, be inserted at least partly the laser tube of debugging portion, for radially adjustingJoint laser tube through several first regulating parts of debugging portion, wherein the outer surface of laser tube is provided with the first regulating part and joinsSeveral that close the first counterpart. Its weak point is that the Level tune of light cannot accurately control, and is unfavorable for lightAutomatically control. And for example application number is 201220007782.8, name is called the Chinese patent of " wireless remote control laser level ", and it is notFoot part be laser level and debugging apparatus integrated, production cost is high, and the adjustment accuracy of integral type is relatively poor.
Summary of the invention
The object of the invention is for existing laser level ubiquity governing speed slowly, labour intensity is large, precisionNot high problem, a kind of method of inventing laser level light Self-regulation track based on servomotor and linear CCD sensor.
Technical scheme of the present invention is:
A method for laser level light Self-regulation track, is characterized in that it comprises the following steps:
