Description

A kind of bamboo chopsticks automatic laser engraving equipment
Technical field
The invention belongs to bamboo chopsticks processing technique field, the skill by computer automatic identification bamboo chopsticks blueness face and yellow face is related to how Art.
Background technology
Trade mark is filled for decoration chopsticks or on chopsticks, more traditional mode is at the butt end one side of chopsticks or four sides Printing mark or decorative pattern, or stick the paster with mark or decorative pattern.But this relatively traditional mode prints Or the mark or pattern being attached on chopsticks are prone to wear out or fall off.The mode of laser engraving compared with tradition prints patch mode then more Stablize.
The common bamboo chopsticks of household generally cut into square bamboo cane by bamboo chip material and are further process, taper end For gripping, sharpening processing is done, section only does chamfered edge processing, retain substantially square section shape close to circle, butt end for holding Shape.In four faces of chopsticks butt end, there are two opposite faces to correspond to the green face of bamboo wood and yellow face respectively.According to the spy of bamboo wood Point, green face fiber compression, color are partially deep, quality is hard, and yellow face fiber is sparse, color is light, quality is soft.Therefore thick in chopsticks In four faces at end, green face quality is most hard, and yellow face quality is most soft, two sides except green face and yellow face, surface texturisation from The side in close Huang face is to the side close to green face by soft to hard gradual change.
Mark or pattern are carved in bamboo chopsticks by way of laser engraving, if having chosen green face and two except yellow face A side, then because case hardness changes, pattern line can have deep mixed phenomenon.Therefore in bamboo by the way of laser engraving Engraving mark or when pattern on chopsticks, should choose green face and/or yellow face and be carved, wherein it is preferred that the most hard green face of quality.Such as choosing Independent face engraving is selected, should be maintained on the same face and carry out in bulk.
To realize the automation of bamboo chopsticks laser engraving, need to meet at 2 points:1, bamboo chopsticks cause laser application station by transmission automatically; 2, be transferred into laser application station bamboo chopsticks blueness face or yellow face just facing towards scanner lens.The common batch for realizing bamboo chopsticks The method automatically delivered is that lower hopper is arranged in transport mechanism rear end, is placed on the chopsticks in lower hopper in batches one by one from blanking The bottom leakage mouth that struggles against leaks out, and is then forwarded one by one by the transfer member below leakage mouth.Obviously, the chopsticks transmitted by this method The direction of son, four faces is random, and to adapt to laser engraving, it is right before bamboo chopsticks are transferred into laser application station to need The direction in four faces of bamboo chopsticks adjusts, and uniformly makes green face or yellow facing towards laser lens direction.It realizes to chopsticks direction Adjustment, key are to realize the automatic identification in four faces of chopsticks.
The recognition methods of presently disclosed bluish yellow face is compared according to the surface color depth and is made, first pre- first in system If a threshold value for representing colour darkness, the value are obtained by lot of experimental data, between green face and yellow face color. In four faces of chopsticks, its excess-three face in addition to green face, color depth is respectively less than the value.This method may be implemented greatly The identification of part chopsticks.But the bamboo wood shade of different batches has different, single threshold value can not be general.
Invention content
