Description
Technical field
The present invention relates to field of laser device technology, be specifically related to a kind of light path compensation system for laser cutting.
Background technology
NC laser cutting is that to metal or nonmetal plate, laser is carried out cutting processing as a kind of manufacturing process, can
In flat sheet, processing linear and the curve of arbitrary shape, be widely used in Electric Manufacture, automobile, meter switch, weaving
Machinery, Transport Machinery, household electrical appliances manufacture, lift facility manufacture, food industry, decoration and advertisement and laser machining station etc..
Existing cut light path includes laser instrument, normal mirror and focus lamp, and the laser beam that laser instrument sends is through one
Series normal mirror reflection after arrive focus lamp, then line focus mirror carry out light beam focusing after sheet material is cut.Laser is cut
When cutting, reflecting mirror is motion, and the length of light path is all the time in change, due to dissipating of laser beam, so the difference at sheet material adds
It is different that station puts its diameter focusing on light beam, thus causes focusing back focus position and depth of focus the most different so that same sheet material
Cut quality declines, and even can not cut.
Summary of the invention
For solving the problems referred to above, the invention discloses a kind of light path compensation system for laser cutting, beam diameter change is little, cuts
Cut quality good.
In order to achieve the above object, the present invention provides following technical scheme:
A kind of light path compensation system for laser cutting, including laser instrument, break-in reflecting mirror, working reflex mirror, focus lamp with cut
Cutting head, focus lamp is positioned at the surface of cutting head, and laser sends through break-in reflecting mirror, working reflex mirror and focusing from laser instrument
Sheet material, to cutting head, is cut by mirror, and working reflex mirror is along with cutting head transverse movement, described laser instrument and break-in reflecting mirror
Between be provided with fixing curvature annular mirror, described fixing curvature annular mirror alignment laser instrument, fixing curvature annular mirror is by Laser emission
To break-in reflecting mirror；Being additionally provided with compensatory reflex mirror between described working reflex mirror and break-in reflecting mirror, described compensatory reflex mirror is pacified
Being contained on horizontal mobile device, described horizontal mobile device is by control system control.
As a further improvement on the present invention, described compensatory reflex mirror is two orthogonal compensatory reflex mirror unit groups
Become.
As a further improvement on the present invention, described fixing curvature annular mirror uses Adoptic-60 type to fix curvature ring
Shape mirror.
The present invention compared with prior art, has the beneficial effect that: fixing curvature annular mirror ensure that light beam is being propagated through
In journey, diameter keeps consistent, does not changes, it is ensured that cut quality；Set up compensatory reflex mirror, for compensating the light of light-conducting system
Shu Changdu so that the beam length of machine cutting far point and near point is equal, becomes aplanatism diced system.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Reference numerals list: laser instrument 1, fixing curvature annular mirror 2, break-in reflecting mirror 3, working reflex mirror 4, compensatory reflex
Mirror 5, focus lamp 6, cutting head 7.
Detailed description of the invention
The technical scheme provided the present invention below with reference to specific embodiment is described in detail, it should be understood that following specifically
Embodiment is merely to illustrate the present invention rather than limits the scope of the present invention.It should be noted that use in describing below
Word "front", "rear", "left", "right", "up" and "down" refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively
It is directed towards or away from the direction of particular elements geometric center.
As it is shown in figure 1, a kind of light path compensation system for laser cutting, sharp for changing including laser instrument 1, break-in reflecting mirror 3(
The direction of propagation of light), working reflex mirror 4, focus lamp 6 and cutting head 7, focus lamp 6 is positioned at the surface of cutting head 7, laser from
Laser instrument sends through break-in reflecting mirror, working reflex mirror and focus lamp to cutting head, is cut sheet material by cutting head,
Working reflex mirror 4 is along with cutting head 7 transverse movement.
In communication process, occur that beam diameter becomes big, that cut quality declines situation, at laser instrument 1 to reduce laser
And between break-in reflecting mirror 3, it being provided with fixing curvature annular mirror 2, fixing curvature annular mirror uses Adoptic-60 type to fix curvature
Annular mirror, fixing curvature annular mirror 2 is directed at laser instrument, and it is anti-that the laser that laser instrument sends is transmitted into break-in through fixing curvature annular mirror
Penetrate mirror.
When cutting head transverse shifting, the light path of laser changes, if the length change of light path is excessive, easily causes and cuts
Cut remote, the difference of near point surface cut quality.In order to solve this problem, also set between working reflex mirror 4 and break-in reflecting mirror 3
Having compensatory reflex mirror 5, in the present embodiment, compensatory reflex mirror is two orthogonal compensatory reflex mirror unit compositions, compensatory reflex
Mirror is arranged on horizontal mobile device, and horizontal mobile device (is not drawn into mobile device in accompanying drawing of the present invention by control system control
And control system).When cutting head transverse shifting X distance, control system controls horizontal mobile device and drives compensatory reflex mirror horizontal
To mobile X distance, equal to ensure the beam length of cutting far point and near point, it is ensured that near point is consistent with the cut quality of initial point.
It is last it should be noted that above example is only in order to illustrate technical scheme and non-limiting technical side
Case, it will be understood by those within the art that, technical scheme is modified or equivalent by those, and
Without departing from objective and the scope of the technical program, all should contain in the middle of scope of the presently claimed invention.
