Description

Tray unit laser engraving device {A LASER MARKING APPARATUS USING TRAY}

[0001] The present invention relates to a laser engraving device, and more particularly, to a tray-based laser engraving device suitable for engraving an object to be engraved in a large amount and at an accurate position.

BACKGROUND ART [0002] In general, a laser engraving device is known that irradiates a laser light onto the surface of a product to mark information related to product manufacturing, such as a LOT number, an article number, a model name, and a manufacturing date.

Conventional laser engraving devices are engraved in units of each product. In other words, an operator puts a product on the engraving table, and the laser device irradiates the laser light to engrave the engraving information on the product.

In the case of such a conventional laser engraving method, since laser engraving is performed only in units of each product, there is a problem that the engraving operation time is lengthened and thus workability is not good, and as a result, the engraving operation efficiency of the product is low.

The following will be described in detail based on the accompanying drawings a preferred embodiment of the present inventors tray unit laser engraving device.

As shown, the laser engraving apparatus in a tray unit according to an embodiment of the present invention is a laser for engraving or marking information such as an article number, a model number, and a manufacturing date with a laser on the object 10 to be imprinted. As an engraving device, a plurality of placement grooves 110a for placing the imprinted object 10 are formed, and sectors S1, S2,...,Sn are allocated to each placement groove 110a on a one-to-one basis.

In the tray-based laser engraving apparatus according to an embodiment of the present invention, the search area F1 is set and stored in a rectangular pattern.

In addition, in the tray-based laser engraving apparatus according to an embodiment of the present invention, the person to be imprinted 10 is a built-in antenna 10 for a mobile communication terminal.

The engraving information 20 is engraved on the object 10 by the laser beam irradiated from the laser module 130 as described above.

In addition, the technique of irradiating the laser beam based on the coordinate value in the laser module 130 itself is a technique known before the filing of the present invention.
