Abstract
The present invention relates to the processes that a kind of optical-fiber laser cutting machine quickly judges protection lens quality, there is following steps: 1) protection eyeglass being mounted in optical-fiber laser cutting machine cutting head, and black photosensitive paper is arranged below cutting head；It 2) is 0mm by the cutting head focus of setting optical-fiber laser cutting machine, power is set as full power, does not install nozzle；3) by decline Z axis, so that the 0mm focus of the cutting head of optical-fiber laser cutting machine is placed exactly in black photosensitive paper surface, then light 20ms out, a hot spot will be formed on black photosensitive paper；4) pass through observation of steps 3) formed hot spot shape and state judge whether the protection eyeglass of optical-fiber laser cutting machine qualified.Low cost of the invention, easy to operate, high efficiency, without processing the protection lens quality quality that can directly judge optical-fiber laser cutting machine.
Description
Technical field
The present invention relates to a kind of protective glasses of optical-fiber laser cutting machine, and in particular to a kind of optical-fiber laser cutting machine is quickly sentenced
The process of disconnected protection lens quality.
Background technique
As optical-fiber laser cutting machine is more more and more universal, corresponding consumptive material demand also starts to increase, and occurs on the market very
The businessman of the protection eyeglass of oversold optical-fiber laser cutting machine, product quality is irregular, since protection eyeglass is a kind of optics production
Product, Hua Chongjin go to buy a special instrument come check protection eyeglass quality it is less existing for terminal laser user
It is real, the way of most of users is exactly the drawbacks of directly eyeglass is tested, done so mounted in equipment top processing side be exactly when
It was found that cutting can not find reason when something goes wrong, while being easy to scrap cutting products, because protection eyeglass problem occurs being to need
Certain preheating time is wanted, is the process of a heat accumulation.The hot spot inner hole that good protection eyeglass is got is rounded, this is ensured that
Consistency of the energy density in each cut direction after laser focuses, in addition hot spot outer ring is without veiling glare, this would not cause
Because there is veiling glare to irradiate and cause fever phenomenon on ceramic ring, nozzle, it is effectively guaranteed the quality and stability of cutting.And compared with
The spot center hole got of protection eyeglass of difference be substantially circle but outer ring be easy linear or drop-wise veiling glare, these veiling glares appearance
Ceramic ring, nozzle fever is easily caused to cause capacitive sensing to go wrong and cutting effect is caused gradually to be deteriorated, very poor protection eyeglass
The inner hole for the hot spot got is not that round and outer ring has linear or drop-wise veiling glare, and this protection eyeglass can constantly cause ceramics
Ring, nozzle fever, but also will have a direct impact on focusing after light spot energy density it is inconsistent in each cut direction, cause cut matter
It measures very poor.
Summary of the invention
Easy to operate the object of the present invention is to provide a kind of low cost, high efficiency can directly judge that optical fiber swashs without processing
The technique of the protection lens quality quality of light cutting machine.
A kind of optical-fiber laser cutting machine of the invention quickly judges to protect the process of lens quality have following steps:
1) protection eyeglass is mounted in optical-fiber laser cutting machine cutting head, and black photosensitive is set below cutting head
Paper；
It 2) is 0mm by the cutting head focus of setting optical-fiber laser cutting machine, power is set as full power, does not install nozzle；
3) by decline Z axis, the 0mm focus of the cutting head of optical-fiber laser cutting machine is made to be placed exactly in black photosensitive paper table
Face, then light 20ms out, will form a hot spot on black photosensitive paper；
4) passing through observation of steps 3) shape of hot spot that is formed and state judge that the protection eyeglass of optical-fiber laser cutting machine is
No qualification.
Wherein, the shape and state of the hot spot include: outer ring and inner hole；When inner hole is non-round, and there is veiling glare in outer ring, then for
Very poor hot spot, protection eyeglass are judged as very poor；When inner hole is round, and there is veiling glare in outer ring, then is poor hot spot, and protection eyeglass is sentenced
It is poor for breaking；When inner hole is round, and outer ring is without any type of veiling glare, then is the normal hot spot that there is no problem, protects eyeglass
It is judged as up-to-standard.
The present invention has the advantages that inexpensive, easy to operate, high efficiency, can directly judge that optical-fiber laser is cut without processing
The protection lens quality quality of cutting mill.

Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Referring to Fig. 1-6, a kind of optical-fiber laser cutting machine of the present invention quickly judges to protect the process of lens quality:
When the protection eyeglass of test will be needed to be mounted in the cutting head of optical-fiber laser cutting machine, by the way that full power is arranged,
0mm focus, does not install nozzle, and the Z axis of mobile laser cutting machine makes cutting head drop to 0mm focus just to put below cutting head
The surface for the black photosensitive paper set, when being provided light between for 20ms, executing out light path sequence makes to burn hot spot on black photosensitive paper
Shape, by the way that (i.e. hot spot inner hole is rounded, and outer ring is without miscellaneous whether there is or not veiling glare around the distribution of the observation entire energy of hot spot and its
Light) judge to protect the quality of eyeglass, the technological operation is simple, quickly goes out as a result, be not limited to the brand of laser cutting machine, does not relate to
And arrive scrap workpieces.
The shape and state of the hot spot include: outer ring and inner hole；When inner hole is non-round, and there is veiling glare in outer ring, then is very poor
Hot spot, protection eyeglass are judged as very poor, see Fig. 2, Fig. 3；When inner hole is round, and there is veiling glare in outer ring, then is poor hot spot, sees figure
4, Fig. 5, protection eyeglass are judged as poor；When inner hole is round, and outer ring is without any type of veiling glare, then there is no problem to be normal
Hot spot, protection eyeglass be judged as up-to-standard, see Fig. 6.
Moving up and down for Z axis is realized by Z axis slide.Z axis slide is the mating mechanism of optical-fiber laser cutting machine.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.Here all embodiments can not be exhaustive.It is all to belong to this work
The obvious changes or variations that the technical solution of skill invention is extended out are still in the scope of protection of the present invention.
