Abstract
The invention discloses a laser cutting machine with an automatic focusing system. The laser cutting machine comprises a machine head (1), a lifting table, a vertical guide rail (2) and a working table (4), wherein the machine head (3) is mounted on the lifting table; the lifting table is movably connected with the vertical guide rail (2); a laser head, a vibrating mirror and a focusing mirror are arranged on the machine head (3); and the laser cutting machine is characterized by further comprising a focus check board and a CPU control device, wherein the focus check board is a thin slab structure which is mounted on the working table (4) when using, and the CPU control device is linked to a transmission device of the lifting table to control the lifting of the lifting table. The laser cutting machine with the automatic focusing system is free from the artificial factors, and convenient, accurate and rapid to focus.
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, 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.Carry out cutting processing with the laser beam after focusing on.The laser beam focusing process of prior art is to utilize laser spot place hot spot little, and the energy density height leaves focus place 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 be subjected to 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]
At the shortcoming of prior art, the object of the present invention is to provide a kind of laser beam focusing process not to be subjected to 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, 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, described 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 lifting 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.
Described 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.
Described 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.
Described focus correction plate be a kind of can be with the thin plate of laser engraving, laser spot is used for getting the rectangle of differing heights in the above when regulating.
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 then to configure, the step number operation, go out a rectangle at each different height control galvanometer and the planned position marking of laser on focus verification plate, after all need figure marking finishes.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, go out a rectangle at each different height control galvanometer and the precalculated position marking of laser on focus verification plate, the CPU control device detect the rectangle carving depth on the focus verification plate and write down focus height that the lifting platform height obtains laser all need figure directly obtain the focus height of laser, and control lifting platform automatically and arrive this highly.
The control procedure of CPU control device can be gone control by software.
The invention has the beneficial effects as follows: human factor influences, focusing convenience that the focusing process is not subjected to, accurately, fast.
[description of drawings]
The invention will be further described below in conjunction with accompanying drawing.
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, described 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 lifting 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.
