If protection is not adequate, the low temperature in winter will damage the laser tube used by the carbon dioxide laser engraving and cutting machine and cannot be recovered! So, today we will take a look at howOnline marking on the fly
The main principle of flying marking is that a rotary encoder is connected to the rotating shaft of the conveyor belt. The galvanometer controller receives the encoder signal and calculates the running speed of the conveyor belt. In this way, the speed advantage of the galvanometer can be used to make the marking content and The timing belt remains relatively static, so that undeformed graphics can be directly printed on the moving timing belt.
Common applications: automated assembly line laser coding, etc.
1D, 2D stitching
The processing range of the galvanometer is limited by the structure of the galvanometer itself. When we need to process some relatively large things, we need to supplement it with another mechanical motion axis. Divided into 1D and 2D
1D, usually add a rotating mechanism, or a linear track, so that the processing length of the galvanometer can be extended in one direction, and the graphics can be automatically divided in SAMLight.
Common applications: marking of rotating objects, processing of Chen roll materials, etc.
2D, usually add two linear tracks to extend the machining length of the galvanometer in both directions.
Common applications: clothing material cutting, large sheet metal surface treatment, etc.
Double-head splicing, multi-head splicing
There are two main modes for using multi-galvanometer splicing to expand processing performance
- Single card double head (only for USC-2)
There are two sets of galvanometer and laser control output interfaces on a single USC-2. Two sets of equipment can be connected. The working graphics must be the same, but independent offsets, processing parameters, calibration files, etc. can be set.
- Doka Long
Multiple USC-1 or USC-2 cards can realize multi-head output function. The output content of each vibrating lens can be seen in SAMLight at the same time. It can support up to 6 cards and 6 heads.

Offline control (USC-2)
USC-2 has 1GB of FLASH storage space, can store 256 files, can be directly used for external triggering, flying marking, etc., it can also directly communicate with USC-2 through RS232, switch files, adjust process parameters, and even change the sequence No. content.
Extended programming and secondary development
The ClientInterface function of SAMLight allows customers to program and control almost all functions of SAMLight. There are many functions like the above picture, which can be programmed in the following two ways. As can be seen in the figure above, each function has two forms, one is Function form and the other is ASCII form.
On the same PC, you can use software programming, directly in the VC, VB, VC# and other programming environments, add a ClientInterfaceOCX control on the Form, you can call various Function functions for programming.
On different PCs (also on this machine), SAMLight can be set as a TCP server, so that you can use TCP to send function commands in ASCII format to the server, and the same function can also be achieved.
3D surface marking
With 3D dynamic focus galvanometer, SAMLight can realize laser scanning on 3D curved surface. Need to activate Optic3D function
Large format marking
With the 3D dynamic focus galvanometer, SAMLight can realize the function of large-format scanning, and the FlatLens function needs to be activated. At present, the common 3D galvanometer is matched with SAMLight, and the format can reach 1500mm x 1500mm. the C02 laser cutting machine should be antifreeze treatment in winter.
Laser tube
The carbon dioxide laser tube is water-cooled, and the temperature is best maintained at about 25 degrees, because the energy is the strongest at this temperature.
In fact, the laser tube is very important to prevent freezing in winter and high temperature in summer. When the laser tube is not working in winter, if the water in the tube is not cleaned, the cooling layer of the laser tube will freeze and expand, and the laser cooling layer will burst, causing the laser tube to fail to work. The freezing and cracking of the laser tube cooling layer in winter are not within the scope of replacement. To avoid unnecessary losses, please do it in the correct way.
First use auxiliary equipment such as air pump or air compressor to clean the water in the laser tube. Customers who use chillers or pumps can remove the chillers or pumps and place them in a high-temperature room to prevent freezing of the water circulation equipment, causing damage to the chillers, pumps and other components, which will bring you unnecessary trouble.
Another thing to note is that do not add too much antifreeze to the laser tube, because the cooling layer of the tube will affect the quality of the light. For laser tubes, the higher the frequency, the higher the frequency of water changes. Otherwise, impurities such as calcium and magnesium in the pure water will adhere to the inner wall of the laser tube and affect the laser energy. Therefore, the most important thing is to change the water frequently and clean the water when not in use.
The chiller is also one of the keys to the antifreeze of laser equipment. In the cold winter, many users think that the water temperature will not rise too much in cold weather. So I often forget to change the water, especially in winter, because the outside temperature is very low, it is difficult to feel the spindle motor heating.
In addition, antifreeze can be used. It is generally composed of alcohol and water. It is required to have high boiling point and flash point, high specific heat and electrical conductivity, low low temperature viscosity, not easy to foam, and not corrode metal parts, hoses, etc. Add it to the matching chiller water tank. The laser equipment can prevent the cooling water from freezing, so that the chiller can start and operate normally in the cold winter.
The above is about the anti-freezing measures of CO2 laser cutting machine in winter. In order to make your laser equipment work better in winter, please master the relevant antifreeze knowledge.
