Abstract
A laser cutting machine with an automatic focusing system comprises a machine head (3), a lifting platform, a vertical guide rail (2) and a worktable (4), wherein the machine head (3) is mounted on the lifting platform; the lifting platform is movably connected with the vertical guide rail (2); and a laser head, a vibrating mirror and a focusing mirror are arranged on the machine head (3). The laser cutting machine with the automatic focusing system is characterized by further comprising a focus checkout board and a CPU (Central Processing Unit) control device, wherein the focus checkout board adopts a thin-slab structure, and is mounted on the worktable (4) when in use; and the CPU control device is connected with a driving device of the lifting platform to control the ascending and descending of the lifting platform. The laser cutting machine with the automatic focusing system is not affected by human factors and is focused conveniently, accurately and quickly.
Description
[technical field]
The present invention relates to aligning automatically, aim at or focusing on of laser beam, laser beam and workpiece have the device with laser beam processing of relative motion.
[background technology]
The laser cutting machine of prior art includes head, lifting platform, setting guide rail and workbench; Head is loaded on the lifting platform; Lifting platform links with the setting guide rail movably; Laser head, galvanometer and focus lamp are arranged on the head, and galvanometer and focus lamp cooperate laser beam are focused on, the processing stand of the focus that cherry picker makes laser beam on the workbench.Laser beam with after focusing on carries out cutting processing.The laser beam focusing process of prior art is to utilize laser spot place hot spot little, and energy density is high, leaves the along laser facula and becomes big, the energy density step-down.In actual process, take a metal calling cards to move by the workman on the workbench surface, whether the size of observing the spark that laser gets on metal calling cards is judged at the laser spot place.This method is time-consuming, and relies on the people to observe spark to determine whether to receive artificial factor in focus, different people operate or same individual to operate the resultant error that obtains in the different moment bigger.
[summary of the invention]
To the shortcoming of prior art, the object of the present invention is to provide a kind of laser beam focusing process not receive human factor influences, focusing convenience, accurately, have the laser cutting machine of autofocus system fast.The technical solution adopted for the present invention to solve the technical problems is: a kind of laser cutting machine that has autofocus system; Include head, lifting platform, setting guide rail and workbench; Head is loaded on the lifting platform; Lifting platform links with the setting guide rail movably, and laser head, galvanometer and focus lamp are arranged on the head, it is characterized in that; Also include focus verification plate and CPU control device, said focus verification plate is a thin-slab structure, is loaded on during use on the workbench, and CPU control device and lifting platform transmission device connect, the up-down of control lifting platform.
Can be printed on the rectangle of height number and planning engraving on the focus verification plate face.Personnel intuitively observe with handled easily.
Said galvanometer and focus lamp are used for laser focusing and control laser position mark and go out to be used for to confirm the figure of focus.Also can stamp other relevant informations.
Said lifting platform is used to drive galvanometer and focus lamp to different height, with in the mark effect that obtains on the workpiece of level altitude under the different focal.
Said focus correction plate be a kind of can be with the thin plate of laser engraving, be used for getting the rectangle of differing heights in the time of the laser spot adjusting in the above.
When laser spot is regulated; Focus verification plate is fixed on the workbench; At first CPU control device control galvanometer and laser beam marking go out every section height indication information, control the step pitch of lifting platform to configure then, the step number operation; Go out a rectangle at each different height control galvanometer with the planned position marking of laser on focus verification plate, all need figure marking end after.Take off focus verification plate, according to the rectangle marking effect on the focus verification plate with highly indicate the focus height directly obtain laser.This belongs to semi-automatic detection.
Can be connected with the carving depth sensor at the CPU control device, be used for the carving depth of detection laser.During focusing; Focus verification plate is fixed on the workbench; CPU control device control galvanometer and laser beam marking go out every section height indication information; And the step pitch of control lifting platform to configure, the step number operation goes out a rectangle at each different height control galvanometer and the precalculated position marking of laser on focus verification plate; The CPU control device detects the rectangle carving depth on the focus verification plate and writes down focus height that the lifting platform height obtains laser the figure that all needs and directly obtains the focus height of laser, and control automatically lifting platform arrival this highly.
The control procedure of CPU control device can be gone control through software.
The invention has the beneficial effects as follows: human factor influences, focusing convenience that the focusing process does not receive, accurately, fast.
[description of drawings]
Below in conjunction with accompanying drawing the present invention is done further description.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of focus verification plate of the present invention;
Among Fig. 1: 1 is that transmission device, 2 is that head, 4 is workbench for erectting guide rail, 3;
Numeral corresponding height value among Fig. 2, rectangle are the figures of planning engraving.
[specific embodiment]
Referring to accompanying drawing, a kind of laser cutting machine that has autofocus system of the present invention includes head 3, lifting platform, setting guide rail 2 and workbench 4; Head 3 is loaded on the lifting platform; Lifting platform links with setting guide rail 2 movably, and laser head, galvanometer and focus lamp are arranged on the head 3, it is characterized in that; Also include focus verification plate and CPU control device, said focus verification plate is a thin-slab structure, is loaded on during use on the workbench 4, and CPU control device and lifting platform transmission device connect, the up-down of control lifting platform.
In the first embodiment of the present invention, be printed on the rectangle of height number and planning engraving on the focus verification plate face.Personnel intuitively observe with handled easily.
In most preferred embodiment of the present invention, the CPU control device is connected with the carving depth sensor, is used for the carving depth of detection laser.
