Abstract
The present invention relates to a kind of laser roller that site is repaiied with thin stroke, including roll body, and the central shaft being connected with roll body, described roll body includes version cylinder and is symmetrically fixed on the plug at version cylinder two ends, described central shaft is through two plugs and is secured to connection, described version cylinder sets nickel coating, copper plate and chromium coating from inside to outside, and described roller repaiies site provided with thin stroke.Compared with prior art, the advantages of word lines effect is more preferable during present invention printing.
Description
Technical field
The present invention relates to a kind of laser roller, more particularly, to a kind of laser roller that site is repaiied with thin stroke.
Background technology
During laser version processing word lines, advantage is that word lines are tangible, and edge is compared with smooth, the no sawtooth of electric carving version.But it is right
Require high in some Product Precisions, and during the thinner word lines of stroke, laser site arranges in edge and lacked, and causes word
Lines effect is undesirable, influences product quality.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of band thin stroke repaiies net
The laser roller of point.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of laser roller that site is repaiied with thin stroke, including roll body, and the central shaft being connected with roll body, described roller
Body includes version cylinder and is symmetrically fixed on the plug at version cylinder two ends, and described central shaft passes through two plugs and is secured to connection, institute
The version cylinder stated sets nickel coating, copper plate and chromium coating from inside to outside, and described roller repaiies site provided with thin stroke.
It is the site being arranged in word lines that described thin stroke, which repaiies site,.
It is as follows that described thin stroke repaiies the specific mending course in site：Small site at stroke edge or not the whole network point, according to
Stroke tendency, big or completion is repaiied by edge site.
Described small site is the site that dot area is less than 0.3 with complete dot area ratio.
Described small site is modified processing by way of directly casting out or merging with neighbour node.
Described not the whole network point is 70% site that dot area meets or exceeds complete dot area.
Described not the whole network point by adjustment position make not the whole network point be changed into the whole network point.
If described not the whole network point can not adjustment position, it is carried out repair big or merged with neighbour node.
The spacing that described thin stroke is repaiied between the middle site in site keeps constant.
Compared with prior art, laser thin stroke of the present invention is after repairing site, and the site of stroke edge becomes big, and edge is more
Plus it is tangible, word lines effect is more preferable during printing.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is comparison diagram of the site with repairing preceding site after present invention repairing.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, should all belong to the scope of protection of the invention.
The present invention avoids laser site arrangement missing, the particularly missing of the small site of stroke edge, using MAC according to laser
Technique repaiies site, and site arrangement is directly filled in the stroke of word lines, is repaired for edge site, makes stroke side
The site of edge is not lacked.
As shown in figure 1, the present invention includes roll body, and the center being connected with roll body with the laser roller that thin stroke repaiies site
Axle 3, described roll body includes version cylinder 1 and is symmetrically fixed on the plug 2 at version cylinder two ends, and described central shaft 3 passes through two plugs 2 simultaneously
Connection is secured to, described version cylinder 1 sets nickel coating 11, copper plate 12 and chromium coating 13 from inside to outside, and described roller is set
There is thin stroke to repair site.
The laser technology formulated according to technologist, site is arranged in the stroke of word lines, small at stroke edge
Site or not site are not located entirely, according to stroke tendency, edge site are repaiied into big or completion, but it is noted that can not change middle part net
Spacing between point.The word lines stroke effect so handled is tangible, is conducive to the effect of tiny stroke lines.Fig. 2 is relatively repaiied
Site and the difference for not repairing site, it is clear that effect is significant.
Wherein described small site A is the site that dot area is less than 0.3 with complete site B area ratios.Described is small
Site A is modified processing by way of directly casting out or merging with neighbour node.
Described not the whole network point is 70% site that dot area meets or exceeds complete dot area.Described is incomplete
Site by adjustment position make not the whole network point be changed into the whole network point.If described not the whole network point can not adjustment position, it is carried out
Repair big or merge with neighbour node.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, various equivalent modifications can be readily occurred in or replaced
Change, these modifications or substitutions should be all included within the scope of the present invention.Therefore, protection scope of the present invention should be with right
It is required that protection domain be defined.
