Abstract
The invention provides a laser marking method for frames at the bottom of a groove of a small-sized workpiece. The laser marking method comprises the following steps: a workpiece to be marked is fixed on a linear motor; when in marking, firstly the linear motor moving the linear motor with the workpiece to a working position I; a laser marking machine makes marks on the frame at the left side of the groove of the workpiece, and after the marking is finished, the linear motor with the workpiece is moved to a working position II; and the laser marking machine makes marks on the frame at the right side of the groove of the workpiece. The laser marking method provided by the invention has the advantages that the linear motor is added on a fixed working platform; by utilization of a method for linear movement, the angle between a laser beam and a workpiece groove wall is enlarged artificially; and under the premise without changing the marking accuracy, the problem that the marks are left on the surface of the top end of the workpiece is effectively solved.
Description
[technical field]
The present invention relates to a kind of laser marking method that is used for miniature workpiece bottom portion of groove frame.
[background technology]
In some workpiece process, need the bottom frame of workpiece groove be got the laser vestige with laser marking machine, do not allow again to stay the mark vestige simultaneously at the workpiece top end surface.As depicted in figs. 1 and 2; The laser head 10 of laser marking machine is got the laser vestige at the bottom frame of the groove 21 of workpiece 20; And workpiece 20 is fixed on the workbench 30; In the mark process, the angle between laser beam 11 and workpiece 20 walls is less, and the horizontal range of workpiece 20 tops and laser beam 11 is less.In the mark process, the angle between laser beam 11 and workpiece 20 walls is less, and the horizontal range d of workpiece top and laser beam 11 is less.Because laser has waveform characteristic, if the mark precision is not enough, will stay the mark vestige on the workpiece top, causes workpiece to scrap.
Under the fixed situation of mark precision, if adopt the existing fixed workbench, might stay the mark vestige at the top end surface of workpiece, have a strong impact on the processing effect of workpiece.
[summary of the invention]
The present invention provides a kind of laser marking method that increases laser beam and workpiece groove walls angle.
The present invention provides a kind of laser marking method that is used for miniature workpiece bottom portion of groove frame; To treat that the mark workpiece is fixed on the straight line motor; During mark, earlier the linear electric motors band workpiece and move to station one position, laser marking machine is in the groove left border marked of workpiece; The linear electric motors band workpiece and is moved to station two positions after mark was accomplished, and laser marking machine is again in the groove Right Border marked of workpiece.
This method has been added linear electric motors on stationary work-table, utilize straight-line method, artificial increase the angle of laser beam and workpiece groove walls.Under the constant prerequisite of mark precision, effectively solved the problem that laser beam is left a trace at the workpiece top end surface.

Combine instance that the present invention is done further description with reference to the accompanying drawings:
Fig. 1 is the sketch map of existing workpiece mark;
Fig. 2 is the structural representation of Fig. 1;
Fig. 3 is the sketch map of laser marking station one of the present invention;
Fig. 4 is the sketch map of laser of the present invention station two up to standard;
Fig. 5 is the station one of Fig. 3 and the combination sketch map of the station two of Fig. 4.
[specific embodiment]
The present invention discloses a kind of at the accurate marking method of miniature workpiece bottom portion of groove enforcement frame; This method is introduced linear electric motors 40 on workbench 30, workpiece 20 is installed on the linear electric motors 40 through workbench 30, then mark partly is divided into two parts; Like Fig. 3 and shown in Figure 4: earlier workpiece 20 is moved to station one position during mark; In workpiece 20 grooves 21 left border marked, mark moves to station two positions with workpiece after accomplishing, again in workpiece 20 grooves 21 Right Border marked.
Moving of workpiece 20 can effectively increase the angle between laser beam 11 and workpiece 20 walls; Equally also increased apart from d, reduced to stay the possibility of mark vestige greatly at the workpiece top end surface, as shown in Figure 5: through repeatedly test proof; Through linear electric motors 40 workpiece 20 is moved to suitable position; The suitable adjustment workpiece and the direction of motor movement axle can effectively solve the problem of leaving a trace at the workpiece top surface, improve the quality of workpiece processing greatly.
