Gas curtain device for adjustment of side-opening laser system and environment isolator

Abstract

The invention provides a gas curtain device for adjustment of a side-opening laser system and an environment isolator. The environment isolator comprises the gas curtain device which comprises a rigid tube and a gas supply device. A gas inlet and a gas outlet are arranged at two ends of the rigid tube, the gas supply device is connected with a gas inlet of the rigid tube, and a plurality of pores which are evenly distributed are arranged on the lower side wall of the rigid tube. The gas curtain device is mounted inside a box of the laser system and is used for producing a gas curtain parallel to the front box wall on one side closed to the front box wall. The invention further provides a corresponding environment isolating method. Compared with the prior art, the gas curtain device and the environment isolator is small in occupied space, convenient to transport and mount, low in the requirement for power distribution, high in isolation effect and low in cost and noise.

Description

technical field [0001] The invention relates to the field of laser technology, in particular, the invention relates to an environment isolation device used for the assembly and adjustment of a laser system for side opening. Background technique [0002] A clean environment is required during laser system debugging, so it is often necessary to isolate the laser from the external environment during debugging. In the prior art, a closed temporary house is generally built for the laser system to be repaired or debugged. The hanging box of the laser system to be repaired or debugged is located in the temporary house. After the external air is purified, the pressure is used to Clean air is blown into the temporary house, and at the same time, the unclean air inside the temporary house is discharged, and the circulation in this way ensures that the air inside the temporary house is clean. This solution achieves the clean environment required for the laser system debugging process ...

AI Technical Summary

Problems solved by technology

This solution achieves the clean environment required for the laser system debugging process to a certain extent. However, it still has the following limitations: (1) It takes up a lot of space, and it is difficult to transport and assemble; (2) The external air flows from above During the process of filtering into clean air through the high-efficiency filter, the high-efficiency filter needs to be replaced regularly (the replacement cycle depends on the cleanliness of the external air), so the cost is relatively high; Dust may be brought in, so complete isolation cannot be achieved; (4) higher power distribution requirements; (5) louder noise
