Description

A laser marking communication system

technical field

The invention belongs to the field of laser marking equipment, and more specifically relates to a laser marking communication system.

Background technique

Laser marking is the use of laser beams to make permanent marks on various material surfaces. The effect of marking is to expose the deep material through the evaporation of the surface material, or to engrave traces through the chemical and physical changes of the surface material through light energy, or to burn part of the material through light energy, showing the required etching pattern, Word. Laser marking has the advantages of fast marking speed, good continuous working stability, and positioning accuracy. It is widely used in the marking of graphics and text in various fields such as electronics, hardware, aviation components, auto parts, metal signs, and LEDs.

Laser marking equipment generally consists of a workbench, a laser, an optical path system and a control system. The workbench of laser marking equipment is generally simply set up as a flat workbench, side rotary chuck, vertical rotary table, or translational conveyor belt. When spherical workpieces such as LED bulb lamps need laser marking in the circumferential direction, It needs to be fixedly placed on the side rotary chuck or vertical rotary table for manual operation. Manual manual operation is to place a workpiece on the rotary device first, wait for the laser to mark a circle around the surface of the workpiece, and then manually Remove the workpiece and place the next workpiece. Its workers take a long time to load and unload materials and cannot work continuously. After loading materials, they need to wait for the laser marking time (generally about 4 seconds) to complete before proceeding to the next material removal action. It takes about 2 seconds for manual loading and 2 seconds for unloading, plus 4 seconds for laser marking, which is equivalent to 8 seconds for a workpiece to be processed. However, the automatic line body of some existing enterprises producing LED bulb lamps requires a production capacity of 1200 pieces per hour, that is, it takes 3 seconds to complete a workpiece product. Processing and production according to the current laser equipment is far from reaching the output, and the labor cost is high, the working time is long, the production efficiency is low, and the market demand cannot be met.

Therefore, the applicant has developed a brand-new laser marking equipment. The laser marking equipment includes a detection platform and an automatic marking system.

Therefore, it is an urgent problem to develop a laser marking communication system that can be equipped with a new laser marking equipment.
