Description of drawings
Fig. 1 shows the rigid pipe structural representation of the air curtain device of one embodiment of the invention;
The environment spacer assembly that Fig. 2 shows one embodiment of the invention is installed on the schematic diagram that side extension laser system is debug.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done further description.
According to one embodiment of present invention, provide a kind of and hung the air curtain device (or being called the gas curtain generating apparatus) that laser system is debug for side, described air curtain device comprises rigid pipe and feeder.Fig. 1 illustrates the rigid pipe structural representation of this air curtain device.As shown in Figure 1, the two ends of rigid pipe 1 have gas access 2 and gas vent 3, and described feeder (not shown in figure 1) is connected with the gas access 2 of described rigid pipe 1.Have a plurality of evenly distributed apertures 4 on the sidewall of the downside of described rigid pipe 1.When feeder was filled with the gas of certain pressure to gas access 2, air-flow sprayed from evenly distributed aperture 4, thereby formed gas curtain, and this gas curtain can play the effect that intercepts dust.
According to another embodiment of the invention, a kind of environment spacer assembly is provided, has comprised air curtain device, described air curtain device is installed in the box house of laser system, be used at the gas curtain that becomes to be parallel to described front side box wall near front side box wall (being case lid to be opened a) adnation.Fig. 2 shows the example that air curtain device is installed on the laser instrument box house, described rigid pipe 1 passes from the box house of described laser system, rigid pipe 1 is near top and the front side box wall of the casing of laser system, and the two ends of rigid pipe 1 have gas access 2 and gas vent 3, and described feeder (not shown in figure 1) is connected with the gas access 2 of described rigid pipe 1.Have a plurality of evenly distributed apertures 4 on the sidewall of one side of described rigid pipe 1.When rigid pipe 1 is installed to the box house of laser system, need to make the aperture 4 of rigid pipe 1 sidewall all under shed.When work, an air curtain that blows from top to bottom can be formed like this, the effect that intercepts dust can be played better.If blow from the bottom up, may cause from operating personnel with it or the dust of other position constantly blown afloat, barriering effect is not good.
In one embodiment, described rigid pipe is metal tube, for example aluminum pipe.
In one embodiment, be spaced apart 1.5cm between the center of described aperture.In general, interval between the center of aperture is not more than 1.5cm and gets final product, can guarantee like this to have enough overlapping rates when gas is blown down, have " air curtain " structure of sufficient density with formation, thus with the overwhelming majority's dust shielding outside the casing of laser system.When technological level allows, can do the interval between the aperture center less (for example less than 0.5cm), the overlapping rate that gas is blown down is higher, more easily forms high density " air curtain " structure, thereby to greatest extent dust is isolated from outside the casing.
In one embodiment, the area of each described aperture is 1cm
2In general, the preferred area of aperture is at 0.19 ~ 1.76cm
2, this is because little hole area when too small, easily blows distortion with the air curtain hole when air pressure is larger, and little hole area is when excessive, the air pressure that can cause blowing at the bottom of the case diminishes, and is difficult to play the effect that intercepts dust.
In one embodiment, the air pressure at place, described gas access is controlled.Described environment spacer assembly also comprises airborne particle counter, and described airborne particle counter is placed in the box house of described laser system, be used for place, described gas access apply different air pressure the time Real-time Measuring measuring tank body inside cleanliness factor.When cleanliness factor reaches requirement, keep the air pressure at place, gas access this moment.
In a preferred embodiment, also provide a kind of environment partition method based on the controlled environment spacer assembly of above-mentioned air pressure, wherein, the air pressure interval at place, gas access can utilize the empty van body to record in advance.Specific practice is as follows: get one and the on all four empty van body of laser system casing to be debugged (describe for convenient, be referred to as with reference to casing), air curtain device is installed to reference in the casing, airborne particle counter is placed in reference to box house.Regulate the air pressure (for example air pressure at place, gas access) of air curtain device, thereby change the gas flow rate of gas curtain, simultaneously with the cleanliness factor of the real-time witness mark box house of airborne particle counter, measure the air pressure interval that cleanliness factor is met the demands.Then, when laser system is carried out actual debugging, before laser system is not opened before the side box wall, place, gas access at rigid pipe passes into little pressure (for example 20Pa) gas and keeps certain hour (for example 30 minutes), to guarantee that gas is full of box house (for example: make box house reach 0.2 atmospheric pressure), then slowly front side box wall screw is unclamped, then gas pressure is increased to and utilize with reference to (for example 5MPa) in the measured air pressure interval of casing to form gas curtain, open rapidly the more front side box wall of laser system (after gas pressure increases, because pressure is larger, need fast case lid to be removed, to avoid the tank wall distortion).This moment the staff just can (directly under external environment) to laser system keep in repair, the work such as debugging.
In addition, the present invention is not only applicable to side and hangs laser system, is applicable to the laser system of uncapping in other side yet, and this is that those skilled in the art are understandable.
At last, the above embodiments only are used for illustrating the present invention, and it should not be construed is that protection scope of the present invention is carried out any restriction.And, it will be apparent to those skilled in the art that do not breaking away under above-described embodiment spirit and the principle, the various equivalent variation that above-described embodiment is carried out, modification and in the text not the various improvement of description all within the protection domain of this patent.
