Embodiment Construction

[0009] Such as figure 1 As shown, the laser beam generated by the laser generating device 1 is reflected or refracted by a group of lenses, and then controlled by the pattern generator 4 to focus on the living object 7 of the workbench 8 in a certain pattern arrangement, and form a certain pattern on it. pattern.

[0010] Such as figure 2 As shown, the laser beam generated by the laser generator 1 enters the X and Y vibrating mirrors 2 through the light guide arm 2, deflects according to the signal generated by the pattern generator 4, and then enters a Fθ lens 5 to focus, and then passes through the light guide tube After 6, inject on the carapace of the living body 7 on the workbench 8. When marking the living body, align the light guide tube with the corresponding part on the living body to mark the living body. The laser marking device of this embodiment is characterized by simple and convenient operation. Even if the laser focused by the Fθ lens is uneven in a certain ...

Abstract

The present invention provides a method for marking animal or plant living body crust under the condition of no damaging living body and its equipment for using said method. The described equipment to formed from laser generator, light-conducting arm, X and Y vibrating mirror, graph generator, F theta lens and light-conducting cylinder. The laser beam produced by laser generator is reflected or refracted by means of one group of lens and focussed on the living body material on the working table under the control of graph generator and a certain pattern is formed on it. Said method is simple and easy to implement, and the mark formed by said method is not easy to be fallen off when it is worked at high temp. or soaked in water.

Description

(1) Technical field [0001] The invention relates to a laser marking method, in particular to a laser marking method on living animal and plant carapaces and a device using the method. (2) Background technology [0002] Fresh crustacean products on the market, such as crabs, come from different places of origin and have great differences in taste and quality. If ordinary anti-counterfeiting stickers are used for marking, they will fall off after high-temperature processing, and the purpose of marking cannot be achieved. . So far no one has used lasers to mark the carapaces of living animals and plants. (3) Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a marking method on the living carapace of animals and plants, which can mark the living body without damaging the living body, which will not fall off under high temperature and soaking. mark. [0004] The method adopted in the present invention is to focus the...
