Anti-condensation protection system and anti-condensation protection method of laser output port

Abstract

The invention discloses an anti-condensation protection system and an anti-condensation protection method of a laser output port, and relates to the field of laser processing. The anti-condensation protection system comprises a controller, related circuits of the controller, a first temperature and humidity sensor and a second temperature and humidity sensor, wherein the first temperature and humidity sensor, the second temperature and humidity sensor, a key module, a displaying module, a Freon temperature regulating device and a dry and humidity regulating device are respectively connected with the controller and the related circuits. When the detected temperature and the detected humidity exceed the preset value, the controller and the related circuits can automatically control the dry and humidity regulating device or the Freon temperature regulating device to work to enable the difference of temperature and humidity at a sealed cavity formed at the laser output port and the external temperature and humidity to recover to the set range. The anti-condensation protection system and the anti-condensation protection method have the advantages that the problem that the laser output port is exposed is effectively solved, the automation degree and the measurement accuracy are high, the laser output port and optical fiber can be effectively prevented from being burned or damaged, a laser processing device is greatly protected, the economic loss is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to an anti-condensation protection system and method for a laser output port, which is suitable for protecting the laser output port of a laser processing machine tool and the optical fiber of the machine tool. Background technique [0002] As an advanced processing technology, laser processing has been widely used at home and abroad. Industrial production mainly includes laser cutting, laser welding, laser remelting, laser cladding, laser engraving and laser processing. The price of the laser output port and the optical fiber connecting the laser output port to the internal laser is very high. The price ranges from a few thousand yuan to tens of thousands of yuan. Therefore, the replacement of the laser output port and the internal optical fiber of the laser processing machine after damage is economical. The price is high. There is a certain difference between the temperature and ...

AI Technical Summary

Problems solved by technology

There is a certain difference between the temperature and humidity inside the laser output port and the external temperature and humidity. Sometimes due to the large temperature difference or humidity difference, condensation on the laser output port is inevitable. If the laser is turned on at this time, the laser output port will If it is damaged, it will burn the output port of the laser or burn out the optical fiber, making the laser unable to work normally and causing huge economic damage

[0003] In the current market, there are few researches on dew condensation at the laser output port. Only a small part of the research is about the condensation alarm device of the laser output window. Low degree and low precision
