In the case of machining that forms dents on the surface, as shown in Figure 3, ashes 1 to dregs and combustion noses blow up,
For this reason, phenomena such as lifting or vibration were observed in the weak parts of the bridge, which was a problem when trying to accurately apply the mask to the workpiece and faithfully perform pattern h. In addition, the combustion residue from the workpiece remains at the upper part, which adversely affects the quality of the workpiece and is not preferable from the viewpoint of protecting the lens.

The laser head disposed on a part of this light-shielding plate irradiates the laser beam and injects the assist gas, and also provides an injection nozzle for injecting the second assist gas. (This assist 1 gas is injected diagonally from above toward the laser beam irradiation site on the workpiece.

In addition, by blowing the combustion gas to the side with the sideways J, stable adhesion similar to light shielding and rapid removal of combustion debris were achieved.

Reference numeral 3 denotes a light-shielding plate placed on the upper surface of the workpiece 1. This light-shielding plate 3 is made of a metal plate with good thermal conductivity, such as copper or brass. Creating processing patterns. Reference numeral 4 denotes a laser head disposed above the workpiece 1, which directs the laser beam 5 oscillated by a laser beam oscillator (not shown) into a condenser lens 6.
11. Focus the light by adding liquid. 1 or the light shielding plate 3. Also, the lower end of the laser head 4 is narrowed to form an injection nozzle 7, from which assist 1 to gas such as air or inert gas is injected downward. 8 is a second injection nozzle arranged on the side of the laser head 4 and injects the second assist gas 1 to the workpiece 1 from diagonally upward toward the laser beam irradiation area. In this configuration, when the laser head 4 scans the entire surface of the light-shielding plate 3 while moving the X-Y table 2, and the laser beam 5 is continuously irradiated, the slits that are not masked will be exposed due to the irradiation effect. It burns, and other parts remain to be engraved in the same shape as the machining pattern.During this machining, the assist 1 gas or combustion gas from the laser head generates a blow-up, and the light shielding plate 3 has an upward direction. A buoyant force acts.However, at the same time, the second assist gas is injected from diagonally above, and its downward force cancels out the above buoyant force.For this reason, the light shielding plate lifts up and the 4 vibrations occur. It is possible to engrave faithfully according to the pattern with the mask perfectly attached to the mask.Also, even if the bridge is bent or floating during the production process, such as a weak part of the bridge, the downward force will keep the workpiece from being engraved. It is possible to closely follow.
