The temperature sensor and the gas pressure sensor are arranged on the inner wall of the lens barrel; a gas inlet and a gas outlet are arranged on the lens barrel and communicated with the inside and the outside of the lens barrel; filtered constant-temperature dry gas is continuously fed into the gas inlet, and the gas ventilation speed of the gas inlet is controlled by the temperature sensor; the gas outlet is provided with a controllable exhaust valve, and the exhausting speed of the controllable exhaust valve is controlled by the gas pressure sensor; and air pressure inside the lens barrel is maintained in stable and positive-pressure state. The laser focal head guarantees stability of a laser optical path and effectively uses optical energy.
Description
Technical field
The utility model relates to a kind of laser process equipment, particularly a kind of laser focusing head with gas shield device.
Background technology
Laser processing technology is a kind of emerging process technology, and it has the efficient height, and cost is low, and pattern and flexible in batches damages advantages such as little to target material.
In laser engraving, mark, welding and the cutting processing, laser beam focuses on the target workpiece through light path, amasthenic lens, can heat micronic dust in the light path and steam in the laser propagation process, amasthenic lens self also can absorb certain heat in aggregation laser, so, prolongation along with the production time, the gas temperature in the light path and the temperature of amasthenic lens all can raise gradually, the utilization ratio of energy has reduced on the one hand, the stability of light path has reduced on the other hand, also may cause consequences such as focal length variations, amasthenic lens damage thus.
Therefore, need a kind of laser condensing lens head, can guarantee the stability of laser optical path, effectively utilize luminous energy with protective device.
The utility model content
In view of this, the utility model provides a kind of laser focusing head with gas shield device, can guarantee the stability of laser optical path, effectively utilizes luminous energy.
The technical scheme that its technical problem that solves the utility model adopts is: comprise lens barrel, speculum, focus lamp and control system, also comprise temperature sensor, gas pressure sensor, air blast, gas-drying apparatus, the gas temperature adjuster, described temperature sensor and gas pressure sensor are arranged on the lens barrel inwall, the output signal of temperature sensor and gas pressure sensor is passed to control system, be provided with on the described lens barrel and be communicated with lens barrel inside and outside air inlet and gas outlet, described air blast gas outlet and gas-drying apparatus air inlet are tightly connected, described gas-drying apparatus gas outlet and gas temperature adjuster air inlet are tightly connected, described lens barrel air inlet and gas temperature adjuster gas outlet are tightly connected, described lens barrel gas outlet is connected with fan inlet, on the connecting line of described lens barrel gas outlet and fan inlet gas supplementing opening is set, described gas supplementing opening is provided with one-way cock, and described air blast is by control system control operation.
Further, the air pressure in the described lens barrel remains on stable barotropic state.
The beneficial effects of the utility model: the laser condensing lens head with gas shield device of the utility model experiment; by the freeze-day with constant temperature gas that continues to feed lens barrel inside is lowered the temperature through filtering; eliminate laser to the heating of lens barrel inside and the heat radiation of processing district; the gas that feeds has passed through and has filtered and drying; do not contain the impurity and the steam that can absorb laser energy; air pressure in the lens barrel remains on stable barotropic state and can prevent that ambient atmos and impurity from entering lens barrel; the utility model has guaranteed the stability of laser optical path, has effectively utilized luminous energy.
