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 for miniature workpiece bottom portion of groove frame.
[background technology]
In some workpiece process, need, with laser marking machine, the bottom frame of work grooves is got laser vestige, do not allow again to leave mark vestige at workpiece top end surface simultaneously.As depicted in figs. 1 and 2, the laser head 10 of laser marking machine gets laser vestige at the bottom frame of the groove 21 of workpiece 20, and workpiece 20 is fixed on workbench 30, in mark process, angle between laser beam 11 and workpiece 20 wall is less, and the horizontal range of workpiece 20 top and laser beam 11 is less.In mark process, the angle between laser beam 11 and workpiece 20 wall is less, and the horizontal range d of workpiece top and laser beam 11 is less.Because laser has waveform characteristic, if mark precision is not enough, mark vestige will be left on workpiece top, cause workpiece to scrap.
When mark precision is determined, if adopt existing stationary work-table, the top end surface likely at workpiece is left mark vestige, have a strong impact on the processing effect of workpiece.
[summary of the invention]
The invention provides a kind of laser marking method increasing laser beam and work grooves wall angle.
The invention provides a kind of laser marking method for miniature workpiece bottom portion of groove frame, to treat that mark workpiece is fixed on linear electric motors, during mark, first by linear electric motors with workpiece movable to station one position, laser marking machine marks on the groove left border of workpiece, marked rear linear electric motors with workpiece movable to station two position, laser marking machine marks on the groove Right Border of workpiece again.
This method with the addition of linear electric motors on stationary work-table, utilizes the method for rectilinear motion, the artificial angle increasing laser beam and work grooves wall.Under the prerequisite that mark precision is constant, effectively solve the problem that laser beam is left a trace at workpiece top end surface.
[accompanying drawing explanation]
In conjunction with example, the invention will be further described with reference to the accompanying drawings:
Fig. 1 is the schematic diagram of existing workpiece mark;
Fig. 2 is the structural representation of Fig. 1;
Fig. 3 is the schematic diagram of laser marking station one of the present invention;
Fig. 4 is the schematic diagram of laser of the present invention station two up to standard;
Fig. 5 is the station one of Fig. 3 and the combination schematic diagram of the station two of Fig. 4.
[detailed description of the invention]
The present invention discloses a kind of at the accurate marking method of miniature workpiece bottom portion of groove enforcement frame, this method introduces linear electric motors 40 on workbench 30, workpiece 20 is arranged on linear electric motors 40 by workbench 30, then mark part is divided into two parts, as shown in Figure 3 and Figure 4: during mark, first workpiece 20 is moved to station one position, workpiece 20 groove 21 left border marks, after having marked by workpiece movable to station two position, then to mark on workpiece 20 groove 21 Right Border.
The movement of workpiece 20 effectively can increase the angle between laser beam 11 and workpiece 20 wall, also increase distance d equally, reduce the possibility leaving mark vestige at workpiece top end surface greatly, as shown in Figure 5: through repeatedly testing proof, by linear electric motors 40, workpiece 20 is moved to suitable position, suitable adjustment workpiece and the direction of motor movement axle, can effectively solve the problem of leaving a trace at workpiece top surface, improves the quality of work pieces process greatly.
Claims (1)
