Problems solved by technology

However, the existing technology cannot meet the requirements of processing on plant leaves. Plant leaves can be made into cards, containers, packaging, etc., and plant leaves are usually very thin. If the laser is uneven, it will penetrate the leaves.
For example, Zongzi, a traditional food loved by the Chinese people, uses reed leaves as packaging materials. In the past, only inkjet coding was used, which was inefficient and harmful to the human body, and could not meet the strict national food production date regulations.

Embodiment Construction

[0020] see figure 1 , 2 , the embodiment of the present invention adopts the computer that stores the marking program to control the laser scanner connected with the laser generator through the numerical control board to mark, and perform the following steps:

[0021] 1) Initialize the system, and set the marking information such as the trademark pattern for marking in the marking program stored in the computer;

[0022] 2) Use the hardware sensor to detect whether the system status is normal. If it is abnormal, it will alarm and wait to be eliminated. If everything is normal, the CNC board will drive the motor of the conveyor belt to move;

[0023] 3) The hardware sensor detects whether there is a product in place. If the product reaches the marking position, call the marking program to start reading the marking information, marking date, and serial number. The font library searches for the character position, reads the character vector coordinate information, generates mar...

Abstract

A laser marking method for plant leaves features that its system is composed of computer with marking program, digital control card, laser device and laser scanner. Said method includes initializing system by imputting marker information to the marking program, testing system state by hardware sensors, invoking the marking program, reading the marking information data and serial number, reading the coordinate information of character vector, generating the marking vector information, optical connecting to obtain final marking vector information, interpolation calculation, D / A converting, driving laser scanner for marking, and judging if duplicate.

Description

technical field [0001] The invention relates to a laser marking method, in particular to a laser marking method on plant leaves. Background technique [0002] Recently, the laser marking method has been used in many different fields, including electronic devices, electrical devices, housings of electrical appliances, automotive parts, mechanical parts, cables, plates, packaging boards, cards, food and drug containers, container covers and Labels, etc., generally used laser marking machines, including laser generators, laser scanners connected to laser generators, and control cards connected to scanners and computers, can realize industrialized high-efficiency and high-quality marking under computer control. However, the existing technology cannot meet the requirements of processing on plant leaves. Plant leaves can be made into cards, containers, packaging, etc., and plant leaves are usually very thin. If the laser is uneven, it will penetrate the leaves. For example, Zongz...
