What is a Laser cleaning control card? What are the main functions?

Laser cleaning technology is a new type of clean and environmentally friendly cleaning and processing technology that has emerged in recent years. Its working principle is to use a high energy laser beam to irradiate the surface of the material, so that the irradiated pollutants expand and evaporate, so as to achieve the purpose of removing stains. Because the laser absorption rate of different materials is different, the adjusted laser irradiation on the material will only remove the stain, and will not damage the material itself.

Compared with traditional cleaning technology such as chemical cleaning and mechanical cleaning, laser cleaning technology has non-abrasive, non-contact, non-thermal effect, and is suitable for various materials of the object cleaning characteristics, coupled with laser cleaning generated less pollution, more friendly to the environment, so laser cleaning technology is also regarded as an important breakthrough in the development of future cleaning technology.

Laser cleaning work needs laser cleaning machine to complete, and laser cleaning machine needs a control system to achieve control, laser cleaning machine generally use motion control card as a control system, because the motion control card is generally the external system of the electronic board card, so the industry also often laser cleaning motion system, referred to as laser cleaning control card.

The main functions of the laser cleaning control card are as follows:

Laser control: One of the most important functions of the laser cleaning control card is to control the start and stop of the laser, including controlling the size of the laser energy by sending the pulse frequency, controlling the length and width of the laser beam by adjusting the galvanometer, and adjusting the shape of the laser during the processing according to the setting of the processing technology.

Information monitoring: In the process of laser cleaning and processing, various information needs to be monitored, including changes in the stain area, changes in material properties, changes in the shape of the workpiece, etc., laser cleaning control card will monitor these information through sensors and other devices, and adjust the laser parameters in real time according to the feedback of the results, so that the processing process can proceed smoothly.

Safety alarm: Laser direct exposure to the human body has some harm, especially handheld laser cleaning equipment, so it must be equipped with the corresponding safety alarm function to ensure that the laser will not be exposed to the human body, or after exposure to the human body will immediately stop the light. In addition, the safety alarm of the laser cleaning control card can also be connected to external devices such as the cooling water tank to monitor and alert the cooling temperature is insufficient.
