Description
Technical field
This utility model belongs to bamboo chopsticks processing technique field, relates to how by computer automatic identification bamboo chopsticks green grass or young crops face and yellow face
Technology.
Background technology
Trade mark is filled for decoration chopsticks or on chopsticks, more traditional mode is at butt end one side or the four sides of chopsticks
Printing mark or decorative pattern, or stick the paster with mark or decorative pattern.But, this relatively conventional mode prints
Or the mark that is attached on chopsticks or pattern are prone to wear out or come off.The mode of laser engraving with tradition print patch mode compared with then more
It is stable.
The bamboo chopsticks of common domestic typically cut into square bamboo cane by bamboo chip material and further process, its its taper end
For gripping, sharpening process is done, section is close to circle, and butt end only does chamfered edge process, retains substantially square section shape for hand-held
Shape.In four faces of chopsticks butt end, there are two relative faces to correspond to the blue or green face and yellow face of bamboo wood respectively.According to the spy of bamboo wood
Point, blue or green face fiber compression, color deep, quality partially are hard, and yellow face fiber is sparse, color is light, quality is soft.Therefore it is thick in chopsticks
In four faces at end, blue or green face quality is most hard, and yellow face quality is most soft, two sides outside blue or green face and yellow face, its surface texturisation from
The side in close Huang face is to the side near green grass or young crops face by soft to hard gradual change.
By way of laser engraving in bamboo chopsticks engraving mark or pattern, if two outside have chosen blue or green face and yellow face
Individual side, then because case hardness changes, can there is deep mixed existing picture in pattern line.Therefore in bamboo by the way of laser engraving
When mark or pattern are carved on chopsticks, should choose blue or green face and/or yellow face and be carved, wherein it is preferred that the most hard blue or green face of quality.As selected
Independent face engraving is selected, should be maintained in bulk on the same face is carried out.
To realize bamboo chopsticks laser engraving automatization, need to meet at 2 points:1st, bamboo chopsticks are caused laser application station by transmission automatically;
2nd, the bamboo chopsticks green grass or young crops face or yellow face of laser application station are transferred into just facing to scanner lens.The common batch for realizing bamboo chopsticks
The method for automatically delivering is to arrange hopper in connecting gear rear end, be placed on the chopsticks in hopper in batches one by one from blanking
Bucket bottom spills mouth and spills, and is then forwarded by the transfer member spilt below mouth one by one.Obviously, the chopsticks transmitted in this way
Son, the direction in its four faces is random, is to adapt to laser engraving, and it is right before bamboo chopsticks are transferred into laser application station to need
The direction in four faces of bamboo chopsticks is adjusted, and unification makes blue or green face or Huang facing to laser lens direction.Realize to chopsticks direction
Adjustment, it is critical only that the automatic identification for realizing four faces of chopsticks.
The recognition methodss of presently disclosed bluish yellow face are contrasted according to the surface color depth and are made, first pre- first in system
If a threshold value for representing colour darkness, the value are drawn through lot of experimental data, between blue or green face and yellow face color.
In four faces of chopsticks, its excess-three face in addition to blue or green face, color depth are respectively less than the value.This method can be realized greatly
The identification of part chopsticks.But, the bamboo wood shade of different batches has different, and single threshold value cannot be general.

The anglec of rotation of the heart and the benchmark image line of centres relative to target direction, and as the current direction in blue or green face/Huang face relative to target
Anglec of rotation R of direction is exported gives upset control unit.
10. bamboo chopsticks automatic laser engraving equipment according to claim 9, it is characterised in that computing comparator calculates four respectively
Average gray in individual identification region, represents with the little of average gray and greatly the height of the region vascular bundle closeness and low.
