Problems solved by technology

[0005] In such a conventional scanning head device, a large amount of smoke (floating foreign matter) is generated at the processing position of the object to be processed on which the laser beam is irradiated, and this smoke is adsorbed to the substrate again to contaminate the object to be processed. Scattering of the irradiated laser beam due to smog causes a problem of degrading the quality of the object to be processed

Abstract

The present invention relates to a laser processing scanner head used as a laser and an air suction hole. More specifically, the purpose of the present invention is to prevent the quality of a workpiece from being deteriorated due to scattering of a laser irradiated by fume generated during laser processing when the workpiece is processed by using the laser. The present invention comprises: a suction unit which sucks air during laser processing and discharges fume to the outside; and an air amplification unit which is used with the suction unit and further supplies air to the suction unit simultaneously with laser irradiation. As the amount and velocity of fume to be removed increase, scattering of a laser irradiated by the fume occurs, and thus it is possible to effectively prevent degradation of the quality of a workpiece.

Description

technical field [0001] The present invention relates to a scanning head for laser processing with both laser and air suction holes capable of preventing the generation of smoke generated during laser processing by supplying air together with laser light to the laser irradiation space at one time and then sucking the smoke. Situations where laser light scatters to cause processing problems. Background technique [0002] In general, various display panel substrates (glass substrates, etc.) include a front surface on which a processed surface is formed and a rear surface on which no processed surface is formed. [0003] Among them, laser etching equipment that processes and etches the edge portion of the above-mentioned glass substrate forming the processed surface with a laser can be used so that the periphery of the processed surface can be cleaned and the subsequent process can be performed smoothly. [0004] In addition, equipment such as a laser drilling machine that proc...
