DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a laser engraving machine having an automatic feeding and focusing function of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a structural view illustrating a laser module according to a preferred embodiment of the present invention. Referring to FIG. 1, the laser module includes a laser module 110, a first transfer unit 120, a second transfer unit 130, The conveyor unit 150, the camera unit 160, and the control unit 180. [0043]

The laser module 110 basically comprises a laser oscillator for generating a laser and an optical system configured to emit the laser generated through the laser oscillator to the work side, .

The first transfer part 120 is installed in a fixed body 101 located on the upper side of the workpiece and is configured to move the laser module part 110 in the X and Y axis directions according to an input control signal, A bar formed in the X-axis and Y-axis directions as in the structure of the scan head, and two motors formed such that the laser module 110 moves along the bar. The structure of the laser module 110 and the first transfer unit 120 is a well-known structure used in a conventional laser processing apparatus, so that detailed description thereof will be omitted in order to prevent blurring of the gist of the present invention.

In the present invention, the laser module unit 110 is configured to be able to output not only a processing laser for processing a material but also a display laser with a relatively weak output level at which damage to the material does not occur. For this purpose, the laser module unit 110 includes a switching unit 111 and uses the same oscillator and an optical system, and controls the output of the laser to selectively output the laser for processing and the laser for display, It is possible to control the selective laser output through the switching unit 111 so as to integrate the separate laser output means.

The second conveying unit 130 may include a stepping motor and a gear, for example, a rack and a pinion gear The height of the laser module unit 110 is adjusted. In the present invention, unlike simple welding or cutting, various sculpting operations including engraving are performed. Therefore, it is important to adjust the focusing position of the laser corresponding to the processing depth. To this end, the second conveying unit 130, The module unit 110 is controlled to the Z-axis position.

The fixing jig 140 is a jig for fixing a workpiece, literally, in various shapes depending on the shape of the workpiece, and temporarily fixed to prevent shaking during laser processing of the workpiece. The processing material can be various stationery or souvenir such as key, paint, pen, lighter, etc. as well as a variety of accessories. In case of a large quantity of processing, it is manufactured as a dedicated jig that can be temporarily fixed .

On the other hand, since the machining material is formed in a somewhat complicated shape, if the machining amount is small, the fixing jig portion can be manufactured in the form of a so-called universal jig that can be fixed corresponding to various shapes. In the accompanying drawings, a fixing jig 140 capable of fixing a workpiece having a length such as a spoon or a pen is shown, but various types of customized or commercial dedicated / universal jigs can be applied to the present invention .

The fixing jig 140 is mounted on the conveyor belt 151 and is conveyed and processed in the form of a workpiece. In order to prevent the conveyor belt 151 from sagging at an intermediate portion thereof, a separate additional plate- 156 are provided inside the conveyor belt. Although the structure of the conveyor part 150 is not largely different from that of a conventional conveyor, in the present invention, a plurality of engaging parts 152, at which the fixing jig part 140 is detached from the conveyor belt 151, The movement of the fixed jig part 140 and the movement during the laser machining are prevented and a precise machining operation is performed.

The camera unit 160 is installed together with the fixed body 101 on which the laser module unit 110 and the first transfer unit 120 are formed to detect the position of the workpiece positioned on the lower side, As shown in FIG.

In the present invention, the controller 180 corresponds to an MCU and is basically supplied with power, A first calculating unit 181 and a second calculating unit 182 for controlling the first transferring unit 120, the second transferring unit 130 and the camera unit 160 including the first transfer unit 110 and the switching unit 111 .

The first calculation unit 181 is configured to analyze the image photographed by the camera unit 160 and measures the spot positions of the display laser formed by dividing the material non-installation state, the reference material installation state, And the height of the target material and the focusing value of the laser module unit 110 are calculated through comparison analysis between the stored images and the newly captured images.

2 is a conceptual diagram illustrating a focusing algorithm according to the present invention.

Referring to FIG. 2, when there is no work material on the lower side of the laser module unit 110, the display laser is displayed at point A of the photographed image substantially corresponding to the upper surface of the conveyor belt.

In the case of the reference material, the material may be a material having a separate unit dimension for calculating the focusing value, or in some cases, a stationary jig 140 in a state where no workpiece is installed. State, the display laser is displayed at the corresponding point D.

After confirming the actual distance of the AD and comparing the distance between the point E and the point A, which is the position of the laser for display when actually photographed with the processed material placed, is compared with the AD distance and the thickness of the reference material already known through actual measurement, And the focusing value of the laser module 110 corresponding to the processing depth can be calculated based on the calculated thickness value.

As a result, the control unit 180 controls the second transfer unit 130 by reflecting the focusing value when the laser beam for processing is output through the laser module unit 110, so that laser processing can be performed at an accurate depth, The first transfer unit 120 is controlled so that a desired pattern is formed.
