Maintenance and advantages of metal laser marking machine

First, laser marking machine maintenance:.

Laser marking machine maintenance generally includes daily maintenance, regular maintenance, regular mechanical inspection and precision inspection, equipment lubrication and cooling system maintenance is also an important part of equipment maintenance, Today, I will share with you the maintenance of laser marking machine.

1. Every time the machine is turned on, check whether there is any sign of looseness in the water joint and whether there is water leakage. If there is water leakage, quickly press the emergency stop switch for maintenance.

2. Keep the inner circulating water clean, observe whether the circulating water has deteriorated every half month, change the water regularly according to the water quality, and replace the filter element. , then this is caused by air blockage in the water pump. Press the red button on the water filter to discharge the air in the water system. After the water flow is normal, the air mixed in the water will reduce the light transmission of the water. If there are air bubbles in the transparent hose or air bubbles at the water return port of the water tank, check whether the return water pipeline is leaking and whether the water level in the water tank is low.

3. Regularly remove dust from the air filter. When there is too much dust, remove the filter and use an air spray gun, water pipe, etc. to remove the dust from the filter. , The laser marking machine allows the filter to dry and then reinstalls it. Generally, it is cleaned once every 2-4 weeks. If the dirt is serious, it can be cleaned with a neutral cleaning agent from time to time. Frequent cleaning of the air filter can prolong the life of the chiller and reduce compression. Electromechanical energy consumption.

4. Clean the radiator in time according to the concentration of floating dust at the place of use, and the degree of dust accumulation on the radiator can be easily observed from the air inlet side of the chassis.

Second, the daily use of laser marking machine precautions.

1. Notes.

①The laser is an air-cooled laser, and the temperature of the working environment (room temperature) is required to be 10°C-35°C (25°C is the best).

②It is strictly forbidden to bend the optical fiber. If it is necessary to bend, make sure that the diameter of the Z small circle of the optical fiber is greater than 20 cm.

③When any abnormal phenomenon occurs, first turn off the power of the laser and the galvanometer, and then check again.

2. Routine maintenance.

①The cleaning of the lens, it is recommended to clean it before work every day, the equipment must be turned off, the cleaning of the focusing lens, gently unscrew the focusing lens from the frame, and clean the lens paper. Bend it into several folds, wet it with cleaning liquid, and wipe the lens surface with the wet lens paper several times until the mirror surface is clean and there is no dust and oil on the lens surface.

② Regularly clean the dust on the surface and inside of the machine to ensure that the internal UV laser marking machine is clean.

③Common troubleshooting.

A, it cannot be turned on. Check whether the power supply is connected or not. Check whether the air switch is closed.

B, the marking has no light and the red light does not display Check whether the laser control wire on the USB card is loose, check whether the 24V switching power supply for the laser power supply is normal, and check the laser cooling fan Is it working properly.

C, the air switch has tripped, and the main circuit has components damaged.

D, the galvanometer does not move, or does not move in one direction, check the XY status indicator of the galvanometer is normal, check whether the galvanometer wiring is loose, check the galvanometer switch power supply If it is normal, check whether the output signal of the USB board galvanometer is normal.

Laser marking machine manufacturers explain that in our daily life, two-dimensional codes can be seen everywhere, such as Internet Alipay, WeChat two-dimensional code, milk powder two-dimensional code in food, etc., Two-dimensional codes are deeply embedded in our lives. On the one hand, it is convenient for users to trace the process of products, and it also serves the purpose of brand promotion.

At present, the application of two-dimensional codes in manufacturing information management systems, food and medicine and other industries, product traceability and sales management, e-commerce and other industries has been very mature, and two-dimensional codes are used in IC. The demand for automatic laser marking machine marking is also growing, but the existing traditional inkjet Leadtech Coding methods such as inkjet, thermal/thermal transfer, etc., have become more and more difficult to meet the application scenarios and functional requirements of QR codes. The emergence of the marking machine has brought a better experience and more possibilities to the application of QR codes.

In the field of consumer electronics, especially in the field of smart phones, there is a lot of pressure on the market for smart phones. Therefore, all smartphone manufacturers strictly control the quality of their products, ranging from electronic components to mobile phone casings, and use laser marking machines to carry out QR codes on them. Marking to achieve traceability of product quality.

Laser marking belongs to non-contact processing, which will not cause other damage to the workpiece during the whole processing process, and there is no ink and other consumables, and will not produce any waste gas, waste water, Avoid contamination.

Two-dimensional codes can carry a large amount of information, which is the basis for product information traceability, but this means that each product can have its own unique two-dimensional code. The two-dimensional code marking machine has a low degree of automation and low efficiency, while laser marking can quickly realize one code for one item.
