The invention has the following beneficial effects:
In silk-screen, marked by the second feature on crawl identification fisrt feature label and silk-screen netting gear for aligning, silk-screen
Fisrt feature label is wiped away after the completion, the appearance of circular substrate will not be impacted, be avoided and increase on circular substrate
The problem of notch, label etc. influence beautiful shortcoming, while can align to avoid artificial range estimation, inefficiency, low precision.
Detailed description of the invention
Fig. 1 is a kind of silk-screen alignment method schematic diagram of circular substrate provided by the invention.
Specific embodiment
The present invention will now be described in detail with reference to examples, and the examples are only preferred embodiments of the present invention,
It is not limitation of the invention.
Referring to Fig. 1, being a kind of silk-screen alignment method of circular substrate provided by the invention, include the following steps:
Step 1, one circular substrate of offer and silk-screen netting gear, the circular substrate include visible area and the silk-screen outside visible area
Area, the visible area are marked equipped with fisrt feature, and the fisrt feature is labeled as erasable ink, are set on the silk-screen netting gear
There is second feature corresponding with fisrt feature label to mark；
Silk-screen netting gear is pre-positioned in the top of circular substrate by step 2；
Step 3 grabs the fisrt feature label on visible area and the second feature label on silk-screen netting gear respectively；
Step 4, contraposition adjust plan-position and the gyrobearing of circular substrate and silk-screen netting gear；
Step 5, by the first silk-screen layer silk-screen in the silk-screen area of circular substrate；
Step 6 repeats step 2 to step 4；
Step 7, by the second silk-screen layer silk-screen in the silk-screen area of circular substrate；
Wipe the fisrt feature label after the completion of step 8, whole silk-screen layer silk-screens away.
In the present embodiment, silk-screen layer has three layers, and the first silk-screen layer is first floor black ink layer, and the second silk-screen layer is the second layer
Dirty oil layer of ink, third silk-screen layer are semi-transparent ink layer, since fisrt feature label is set to the visible area of circular substrate, when silk-screen,
Fisrt feature will not be marked and be covered by silk-screen layer, and every layer of silk-screen layer can be marked by fisrt feature for aligning, thus really
The aligning accuracy of every layer of silk-screen layer is protected, in other embodiments, silk-screen layer can be four layers, five layers or multilayer, should all fall
Enter within protection scope of the present invention.
Second feature label on silk-screen netting gear can be the auxiliary para line being directly produced on silk-screen netting gear, lead to simultaneously
It crosses hinge or transparent mesh seal paste is sealed off that it can not make ink, only used for contraposition.For there is automatic decimal alignment system,
It can be achieved to grab mark raising aligning accuracy automatically.It for being fitted without automatic decimal alignment system, can be aligned by human eye, improve contraposition
Efficiency and precision.
In silk-screen, marked by the second feature on crawl identification fisrt feature label and silk-screen netting gear for aligning,
Fisrt feature label is wiped away after the completion of silk-screen, the appearance of circular substrate will not be impacted, be avoided on circular substrate
The problem of increase notch, label etc. influence beautiful shortcoming, while can align to avoid artificial range estimation, inefficiency, low precision.
Further, the shape of the silk-screen netting gear is circle, the center of circle and the circular substrate of the silk-screen netting gear
It is round corresponding.Fisrt feature label and second feature label can pass through one characteristic point of setting or a characteristic curve at this time
Section is adjusted to realize to align.
Further, the step 5 specifically includes:
Step is 1.: according to the same of the location confirmation circular substrate and silk-screen netting gear in the center of circle of circular substrate and the center of circle of silk-screen netting gear
Axis degree relationship is simultaneously adjusted its plan-position；
Step is 2.: according to the angle of fisrt feature label and angular relationship the confirmation circular substrate and silk-screen netting gear of second feature label
Degree relationship is simultaneously adjusted its gyrobearing.
When fisrt feature label and second feature are labeled as characteristic point, line can be formed by the line in characteristic point and the center of circle
Section realizes that gyrobearing is adjusted by comparing the angular relationship of two lines section.Characteristic curve is preferably used in the present embodiment
Section compares the angular relationship of two Eigenvectors directly to realize that gyrobearing is adjusted, to improve aligning accuracy, reduces and misses
Difference.
Further, the center location of circular substrate and silk-screen netting gear is confirmed by alignment system.It is automatic to improve
Change and accuracy rate.
Further, the fisrt feature is labeled as two line segments being not parallel to each other.Silk-screen netting gear can be any at this time
Shape, without using the silk-screen netting gear of particular circle, the second feature label on silk-screen netting gear is corresponding with fisrt feature label,
Contraposition is realized by two not parallel line segments.
Further, the fisrt feature is labeled as non-dots symmetric figure.With prevent crawl identification fisrt feature label and
Anisotropy when second feature marks, avoids to bit-errors.
Further, identify that the fisrt feature label and second feature mark by video camera crawl.To improve certainly
Dynamicization and accuracy rate.
Further, the fisrt feature label and second feature label can be and be completely coincident, and be also possible to shape phase
Together, ratio is different.When fisrt feature label is identical with the shape that second feature marks, when dimension scale is also identical.
It can confirm angular relationship by matching lines, to realize that silk-screen aligns；When fisrt feature label is marked with second feature
Only shape is identical, when ratio difference, can make fisrt feature by way of scaling fisrt feature label or second feature label
Label and second feature label reach the condition of coincidence, and then complete the confirmation of angular relationship.
Further, the fisrt feature is labeled as oil-soluble oil ink.It is easy wiping, it is not easy to leave a trace, wipe away
Circular substrate afterwards is more beautiful.
A kind of circular cover comprising circular substrate, the circular substrate include visible area and the silk outside visible area
Area is printed, the visible area is marked equipped with fisrt feature, and the fisrt feature is labeled as erasable ink, the fisrt feature mark
Remember corresponding with the second feature label being set on silk-screen netting gear to realize contraposition.It is special by crawl identification first in silk-screen
Second feature on sign label and silk-screen netting gear is marked for aligning, and wipes fisrt feature label away after the completion of silk-screen, will not be right
The appearance of circular substrate impacts, and avoids and increases the beautiful shortcoming of the influence such as notch, label on circular substrate, while can
To avoid artificial range estimation contraposition, the problem of inefficiency, low precision.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
