Product Description

Laser engraving machine for pad printing steel plate:

Laser generator

This is the core component, which produces a high-energy-density laser beam. For example, a carbon dioxide laser can output a laser of a specific wavelength, and its energy is concentrated, which can instantly melt or vaporize the surface material of the pad printing steel plate.

Optical transmission system

Includes reflectors and focusing lenses. The reflectors change the propagation direction of the laser beam so that it can accurately reach the position to be engraved on the pad printing steel plate; the focusing lens focuses the laser beam to a very small spot, improves the energy density of the laser, and ensures the engraving accuracy.

Motion control system

It consists of a motor, a guide rail, and a controller. The motor drives the workbench or the laser head to move along the guide rail, and the controller accurately controls its movement trajectory and speed, so that the laser beam can be engraved on the pad printing steel plate according to the preset pattern, such as when engraving complex patterns or fine text, high-precision path control can be achieved.

Auxiliary system

Covering the cooling system and the exhaust system. The cooling system prevents the laser generator and the optical transmission system from being damaged due to overheating, and the exhaust system promptly removes the smoke generated during the engraving process to ensure a good working environment and normal operation of the equipment.

 Machine features:

• Integrated overall structure, equipped with automatic focusing system, humanized operation process.
• Imported isolators are used to protect the fiber laser window, enhance stability and laser life.
• The beam quality is significantly improved compared with traditional solid lasers, with fundamental mode (TEM00) output and a focused spot diameter of less than 20um. The divergence angle is 1/4 of that of semiconductor pumped lasers. It is particularly suitable for fine and precise etching.
• The electro-optical conversion efficiency is high, and the power consumption of the whole machine is less than 800W, which is 1/10 of that of lamp-pumped solid laser marking machines, greatly saving energy consumption.
• No special maintenance is required, the service life is long, the size is small, and it is suitable for working in harsh environments.
• Simple and easy to learn, after programming, the equipment automatically completes the etching process of the pattern.
• The whole machine performs laser processing in a closed environment to improve the factory's safety production level.
   

Working environment requirements

• The ambient temperature is required to be between 15~40℃.
• The humidity requirement is 40%-80%. To ensure no condensation, it is recommended to install a dehumidifier.
• Power grid requirements: 220V; 50Hz.
• Power grid fluctuation: ±5%, the grid ground line meets international requirements. In areas where the voltage amplitude is more than 5%, electronic automatic voltage and current stabilization devices should be installed.
• There should be no strong electromagnetic signal interference near the installation equipment. Avoid radio transmitters (or relay stations) around the installation site.
• Foundation amplitude: less than 50um; Vibration acceleration: less than 0.05g. Avoid a large number of stamping and other machine tools nearby.
• Equipment space requirements must be smoke-free and dust-free, and avoid working environments with severe dust such as metal polishing and grinding.
• Air pressure: 86-106kpa.
• Anti-static floors should be installed in some environments to strengthen shielding, etc.

Application︰
Pad printing steel plates are gravure plates, and the graphic part of them is lower than the surface of the plate base. They are usually made by liquid etching, which is a relatively complicated process and causes certain damage to the environment. The method of laser etching has been explored by the industry. The breakthrough development of laser technology has laid the foundation for the direct etching of pad printing steel plates. The laser etching machine uses the top domestic high-power laser and high-quality galvanometer scanning system, which can achieve rapid etching of thick steel plates and thin steel sheets above 0.3mm. It is the best choice to replace the traditional etching method for making steel plates.
