Problems solved by technology

[0014] The solutions disclosed in the prior art are partly constructed in a technically very complex manner
This increases the cost of the laser beam machining device and also makes it prone to failure
And, despite the complexity of these machines, they are poorly adaptable

Embodiment Construction

[0055] figure 1 An exemplary laser beam machining device 1 is shown, for example, comprising a diode laser 2', an optical fiber 3, a machining head 4, a gantry slide 5 and a rail 6, and a workpiece machined by the laser beam machining device 1 7.

[0056] figure 1 The laser beam machining device 1 shown in has the following functions:

[0057] The machining head 4 itself can move along the way of the gantry sliding device 5 in the direction x, and the gantry sliding device can move along the track 6 successively in the direction y, so that the machining head 4 can perform the operation on the x-y plane. any movement on the With the aid of the diode laser 2 , laser light is generated which is guided by means of an optical fiber to the machining head 4 where it is then directed onto the workpiece 7 . The laser beam A then touches the workpiece 7 at the machining point. During the movement of the machining head 4, the workpiece 7 is then cut along the path traveled by the ma...

Abstract

A laser beam machining device (1)is provided,in which unfocused light(A) from a light exit point(B)is radiated onto a single lens (8),where in the lens(8)focuses the laser light (A)and guides it onto a machining point of a work piece (7). A distance (ma, mb) between the lens (8) and the light exit point (B) and a distance (la, lb) between the lens (8) and the machining point of the workpiece (7) and a distance between the light exit point (B) and the aforementioned machining point can be varied. Moreover, a process of usage of a laser beam machining device (1) is provided.

Description

[0001] This application claims foreign priority from EPO application (serial number EP10195433) filed December 16, 2010 and also claims priority from US provisional application (serial number 61 / 423,992) filed December 16, 2010 And as its non-provisional applications, EPO Application EP10195433 and US Provisional Application Serial No. 61 / 423,992 are hereby expressly incorporated by reference in their entirety for all intents and purposes, as if as fully set forth herein. technical field [0002] The present invention relates to a laser beam machining device comprising a light exit point emitting unfocused laser light and a single lens following the light exit point in the direction of radiation, while the single lens focuses the laser light and is designed as the laser light to be focused Guided to the machining point of the workpiece, and the single lens can move along the radiation direction. Furthermore, the invention relates to the use of a laser beam machining device. ...
