Abstract
The invention relates to a laser cutting machine capable of maintaining the equal light beam size. The laser cutting machine comprises a workbench, a pen vehicle and a beam expander, wherein the pen vehicle is movably arranged on the workbench, the pen vehicle cuts to-be-machined workpieces on the workbench by receiving laser beams output by a laser tube, the beam expander is arranged on the output path of light beams output to the pen vehicle by the laser tube, laser beams pass through the beam expander and the pen vehicle sequentially, the beam expander is movably arranged on the workbench, and the displacement distance of the beam expander changes along with the displacement distance of the pen vehicle, so that laser beams generate focus points of the same size after being output. Any position of the table top of the laser cutting machine can maintain the same cutting quality.
Description
Technical field
The present invention is about a kind of laser cutting machine maintaining beam sizes equalization, espespecially one utilizes portable beam expanding lens, make to move to diverse location with parking stall of beginning to write, and adjust the size of light beam, make laser cutting machine all maintain identical cutting quality in any position of table top.
Background technology
Now in the output for printing industry, mainly include laser engraving/cutting and ink jet printing, the general principle of general laser machine, mainly guides the light beam of Laser output and focuses on the surface by carving object, the light beam after focusing, absorb through material, temperature suddenly raises and gasifies, and makes object surface recessed, also or by focus on after high-energy light beam heating and melting work piece surface, blow down melted material with gases at high pressure simultaneously, and reach the object of engraving or cutting.
Current large laser cutting machine, its casing internal arranges high wattage laser tube, but due to board table top large, cause laser beam because of the impact of its angle of divergence, under equal-wattage and frequency, but can not reach identical cutting quality.In addition, the out-of-flatness factor that the tolerance due to board table top causes, makes the focal length of table top under diverse location have narrow difference, also can affect cutting quality.
In view of this, how to make laser cutting machine all maintain identical cutting quality in any position of table top, always for industry endeavours to study the direction with improvement.
Summary of the invention
Main purpose of the present invention is providing a kind of laser cutting machine maintaining beam sizes equalization, and when the parking stall on its board moves to diverse location, the size adjustable of light beam, makes laser cutting machine all can maintain identical cutting quality in any position of table top.
In order to achieve the above object, a kind of laser cutting machine maintaining beam sizes equalization provided by the invention, it comprises a work table, car and a beam expanding lens.Wherein this car is movably located on this work table, the workpiece to be added that this car is opposite on this work table by the laser beam receiving laser tube output cuts, and this beam expanding lens is located at laser tube and is exported in the outgoing route of the laser beam of a car, laser beam is sequentially via beam expanding lens and a car, wherein, this beam expanding lens is movably located on this work table, and the distance of this beam expanding lens displacement distance of moving with parking stall of beginning to write and change laser beam is exported after produce the focus point of formed objects.
During enforcement, this car and this beam expanding lens are arranged on identical or different working track.
The invention has the beneficial effects as follows:
Beam expanding lens of the present invention is movably located on work table, and the distance of this beam expanding lens displacement is the distance of moving with parking stall of beginning to write and changes, the focus point of formed objects can be produced after laser beam is exported, make laser cutting machine all can maintain identical cutting quality in any position of table top.
For understanding the present invention further, below lifting preferred embodiment, coordinating accompanying drawing, figure number, concrete constitution content of the present invention and effect of reaching thereof are described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the three-dimensional appearance schematic diagram of the embodiment of the present invention.
Fig. 2 is the configuration diagram of the embodiment of the present invention.
[main element symbol description]
1: work table 2: a car
3: beam expanding lens 4: laser tube
5: workpiece 6 to be added: working track.
Detailed description of the invention
Refer to Fig. 1, Fig. 2, it can maintain the configuration diagram of an embodiment of the laser cutting machine of beam sizes equalization for the present invention, and it is made up of a work table 1, car 2 and a beam expanding lens 3.
This car 2 is movably located on this work table 1, the laser beam that this car 2 exports in order to be received from laser tube 4, the workpiece to be added 5 be opposite on this work table 1 is cut, and this beam expanding lens 3 is provided at laser tube 4 in the laser beam outgoing route of a car 2, laser beam is sequentially exported via beam expanding lens 3 and a car 2 are rear, wherein, this beam expanding lens 3 is movably located on this work table 1, and the distance of this beam expanding lens 3 displacement changes with the distance of car 2 displacement of beginning to write, the focus point of formed objects after exporting so as to making laser beam, can be produced.
Wherein, this car 2 is be arranged on identical or different working track 6 with this beam expanding lens 3.
Therefore, during enforcement, as shown in Figure 1 and Figure 2, when a car 2 moves, beam expanding lens 3 can displacement thereupon, and the distance of its movement adjusts multiplying power with the coordinate value of car 2 movement of beginning to write, certainly, this part be by software and computer processing unit to carry out computing and the shift length controlling this beam expanding lens 3, make laser beam export the focus point that can maintain formed objects.
Whereby, by the design that the present invention is above-mentioned, utilize beam expanding lens 3 to be moved to diverse location with car 2 of beginning to write, and adjust the size of light beam, make laser cutting machine all maintain identical cutting quality in any position of table top.
The above technological means being specific embodiments of the invention and using, can derive according to exposure herein or instruction and derive many changes and correction, still can be considered that the equivalence that conception of the present invention is done changes, its effect produced does not exceed the connotation that description and accompanying drawing are contained yet, all should be considered as, in technology category of the present invention, closing first Chen Ming.
In sum, according to content disclosed above, the present invention really can reach the expection object of invention, provides a kind of laser cutting machine maintaining beam sizes equalization, has the value that industry utilizes, and whence proposes application for a patent for invention in accordance with the law.
