Abstract

The present invention discloses a control method for laser emission assisted by an optical lens seat in a laser machining machine. The control method comprises the steps that when the laser optical lens seat is driven to pass over a working substance, a work area is divided into three parts; in the first part, the laser optical lens seat is in the state of acceleration; in the second part, the laser optical lens seat is in the state of constant velocity; in the third state, the laser optical lens seat is in the state of deceleration; when the laser optical lens seat is positioned in the area of constant velocity, the laser optical lens seat is made to keep normal output power; when the laser optical lens seat is positioned in the area of acceleration, the laser optical lens seat relatively enlarges the output power; when the laser optical lens seat is positioned in the area of deceleration, the laser optical lens seat relatively reduces the output power; the laser irradiation quantity of each removed unit is equal so as to reduce working time. By using the control method, edges do not need to be preset at both sides during processing, processing speed can be accelerated, and the working time is reduced.

Description

The optics microscope base cooperates the control method that penetrates laser in the laser machine

Technical field

Background technology

In traditional laser machine, when laser optics microscope base A reverses on slide rail B when doing, generally can be in unidirectional stroke through quickening, the constant speed and the three kinds of processes of slowing down, as shown in Figure 1, because the speed of laser optics microscope base A is the most steady appropriate in constant speed district F, and traditional laser diode output control is certain, for prevention work thing D be placed into workspace C about speed inequality during two limits, and influence the exposure inequality of laser in each unit of removing, therefore workspace C is only in the constant speed district of centre F, formed the limit and in the left accelerating region E of this workspace C and right-hand deceleration area G, can't work, so when working substance D is strengthened, also need strengthen the area of constant speed district F, relative whole workspace C also must increasing can make working substance D place constant speed district F just, the unlikely working substance D that influences, but no matter how its method changes in the C of workspace, still have only among the constant speed district F and can work, and accelerating region E and deceleration area G can't use, and cause waste.

As shown in Figure 2, because of laser optics microscope base A in when work, by opening the beginning the one fixing distance of walking must be arranged when quickening to reach constant speed, as 4cm, yet the area of working substance very hour, as 2 centimetres, with traditional arrangement works method, in construction, promptly can produce accelerating region E and deceleration area G both sides and stay limit 8cm altogether, situation much larger than middle constant speed district F2cm, and allow laser optics microscope base A must be in a bigger sash 10cm about back and forth action can the small articles of a 2cm be processed, cause meaningless virtual work.

Therefore the creator among the present invention through concentrating on studies and developing, draws a kind of control method that can accelerate optics microscope base cooperation ejaculation laser in process velocity, the laser machine of reduction working time in view of the deficiency of above-mentioned conventional method eventually.

Summary of the invention

The control method of optics microscope base cooperation ejaculation laser mainly is bigger in order to solve existing control method waste in the laser machine of the present invention, and the useless problems such as virtual work that are easy to do.

The control method that the optics microscope base cooperate to penetrate laser in the laser machine among the present invention is:

A. when the laser optics microscope base is crossed working substance by drive, the workspace is divided into three parts;

Be acceleration when b. making the laser optics microscope base be in first, when second portion, be constant speed and when third part, be deceleration;

C. make the laser optics microscope base when the constant speed district, keep normal power output, when accelerating region, strengthen power output relatively, and power output reduces relatively when deceleration area;

The sharp quantity of illumination of each unit of removing is equal to, with the reduction working time.

In addition, when the working substance area hour, the laser optics microscope base is divided into the workspace three parts equally, and the mesozone is invented one slows down and open initial line.

Required mobile distance when utilizing control method among the present invention to shorten work is accelerated process velocity, the reduction working time.

The specific embodiment

As shown in Figure 3 and Figure 4, the laser optics microscope base cooperates the control method that penetrates laser to be among the present invention: at first working substance is placed on the working face of laser machine 1, again required pattern is input in the laser machine 1, when laser optics microscope base 12 is crossed working substance 16 by guide rod 11 drives, incised work district 10 is divided into three parts, is defined as for convenience of description and opens begin district 13, mesozone 14 and end region 15.When laser optics microscope base 12 places when opening beginning district 13, this laser optics microscope base 12 itself quickens and strengthens power output, and when laser optics microscope base 12 when entering into mesozone 14, this laser optics microscope base 12 is constant speed and keeps normal power output, moreover, when laser optics microscope base 12 enters end region 15, itself be deceleration and reduce power output relatively, so repeatedly till finishing figure, by this, make the laser exposure of each unit of removing identical, and the limit of need not leaving a blank in advance in working substance 16 both sides, thereby process velocity can be accelerated with the reduction working time.

Shown in the 5th figure, during at these laser optics microscope base 12 work, the one fixing distance of walking must be arranged in the time of will arriving constant speed by the acceleration of opening the beginning, very little as working substance 16 areas, during as 2cm, this laser optics microscope base 12 may be used in processing less than the mesozone 14 that enters constant speed at all, promptly enter into end region 15 again after beginning district 13 quickens and slow down at once once entering into to open, and do not need constant speed through mesozone 14, therefore when working substance 16 hour, then make laser optics seat 12 convert automatically according to the size of working substance 16 areas, equally workspace 10 is divided into three districts, but 14 virtual being re-established as in the mesozone of original constant speed are that initial line is opened in a deceleration, when making laser optics seat 12 enter into opening the deceleration of walking to virtual mesozone 14 after the beginning, district 13 quickened to open initial line (not reaching before former guide's speed), promptly directly entering end region 15 slows down, make laser optics seat 12 one with big 2cm sub-district lattice such as working substance 16 grades in quicken back and forth about doing, slow down to switch, can process this unskilled labourer crop 16 fast and effectively reduce the working time.

As Fig. 4 and shown in Figure 6, the work flow of preferred embodiment is the speed that the speed that at first moves by decoder records motor among the present invention, thereby the present position of laser optics microscope base 12 as can be known, and convert the speed speed of decoder to size through a conversion module, then again through a comparator, because of the speed difference, power is also different, the data of timer and comparator is input in the laser energy machine in the lump in addition, the timing of nationality timer is inequality with the laser power that different instantaneous velocitys and different laser power make laser optics microscope base 12 penetrate again.

The control method of projected laser matched with optical lens seat in laser processing machine of the present invention has following advantage:

1. by means of the laser optics microscope base incised work is distinguished and be slit into Qi Shiqu, mesozone and end region, and Make the laser optics microscope base open the district's acceleration of beginning, mesozone constant speed, end region deceleration, make the laser of each unit Exposure is equal to, and the virtual work of doing owing to Liu Bian has been saved in both sides when construction, accelerates process velocity, contracting The casual labourer does the time.

2. the laser optics microscope base is driven when crossing the workspace, and tablet pattern is divided into three districts, so laser The optical lens seat location is Qi Shiqu (opening the district of beginning can exchange mutually with end region), when the laser optics microscope base from a left side To the right side finish the action after, also can move from right to left, do not need to come back to again the left side could not move.

3. the control method among employing the present invention can make laser machine that littler working substance is being added man-hour, Avoided tradition to leave the super large limit in the working substance both sides, and produced the deficiency of virtual work, therefore to little working substance Process velocity on more obvious.
