On the other hand, when gas is sprayed (reference picture 2B), valve 4 is due to deadweight or the pressure of the gas in cardinal extremity passage 6
(malleation) and decline, block central passage 7 using compression face 13, cardinal extremity passage 6 and central passage 7 are mutually disconnected, to refuse
Gas is sprayed from central opening 10.Now, cardinal extremity passage 6 and multiple circumferential passages 8, are connected with each other by passage 15, it is allowed to
Gas is sprayed from multiple circumferential openings 11.
Multiple pressing members 5, respectively with above-below direction (the upper direction in Fig. 2A and Fig. 2 B, the inside and front in Fig. 3
Direction) on the state that can move back and forth, in pressing member receiving space 9.These multiple pressing members 5 have respectively
2 Rotating fields, wherein, the diameter of base end side (upside in Fig. 2A and Fig. 2 B, the inner side in Fig. 3) is relatively large, tip side (Fig. 2A
With the downside in Fig. 2 B, in Fig. 3 with front side) diameter it is relatively small.
Also, the diameter of the base end side of multiple pressing members 5, respectively than pressing member receiving space 9 base end side it is straight
Footpath is smaller, and bigger than the diameter of the tip side of pressing member receiving space 9.In addition, the tip side of multiple pressing members 5 is straight
Footpath, it is more smaller than the diameter of the tip side of pressing member receiving space 9 respectively.
Such multiple pressing members 5, respectively as the function of projection 17 projected from prominent opening 12.That is, suction is worked as
(with reference to Fig. 2A) during bleed body, multiple pressing members 5 rise respectively by the pressure (negative pressure) of the gas in cardinal extremity passage 6,
Projection 17 is set to retract from prominent opening 12.On the other hand, when gas is sprayed (reference picture 2B), multiple pressing members 5 are borrowed respectively
The pressure (malleation) of the gas in helping deadweight or cardinal extremity passage 6 and declines, make projection 17 from the prominent protrusions of opening 12.
Also, the diameter phase of the base end side (upside in Fig. 2A and Fig. 2 B, the inner side in Fig. 3) of the pressing member 5 for declining
To larger part, tip side (downside in Fig. 2A and Fig. 2 B, the front in Fig. 3 in pressing member receiving space 9 is blocked
Side) the relatively small part of diameter.Spray from prominent opening 12 thereby, it is possible to prevent gas from passing through pressing member receiving space 9
Go out.
So, gas (the cardinal extremity passage for attracting or spraying is born by the cardinal extremity (omission reference) by pressing member 5
Gas in 6) pressure, projection 17 carries out action by the pressure of the gas.Also, (the reference picture when gas is sprayed
2B), projection 17 becomes the state projected from top ends 3a of suction nozzle main body 3, the on the other hand, (reference picture when gas is attracted
2A), projection 17 becomes the state kept out of the way from top ends 3a of suction nozzle main body 3.
Then, using Fig. 4 A and Fig. 4 B, the flow process to adsorbing lens XA1 is illustrated.Fig. 4 A, are the sectional view of suction nozzle 2,
Represent the state before absorption lens XA1.Fig. 4 B are the sectional view of suction nozzle 2, represent the state after absorption lens XA1.This
Outward, on the lens XA1 adsorbed by suction nozzle 2, it is placed with ring XA2s of the lens XA1 with band.
First, as shown in Figure 4 A, top ends 3a for making suction nozzle main body 3 drop to the height that will be abutted with lens XA1.By
This, central opening 10 is relative with the approximate centre of lens XA1.Also, multiple circumferential openings 11 respectively with positioned at lens XA1 week
The flange portion (omission reference) for enclosing is relative.In addition, each multiple projections 17 projected from prominent opening 12 respectively with mounting
Ring XA2 on lens XA1 is relative.
Then, negative pressure is produced by pump unit (omitting diagram), as shown in Figure 4 B, prominent multiple projections 17 keep out of the way each
In prominent opening 12, and attract gas from central opening 10 and multiple circumferential openings 11.From the gas that central opening 10 attracts
It is directed along central passage 7.The gas attracted from multiple circumferential openings 11 is directed along each circumferential passages 8.Thus, in shape
Negative pressure is produced into the space (omission reference) between top ends 3a of suction nozzle main body 3 and lens XA1, by the negative pressure,
Lens XA1 is adsorbed in top ends 3a of suction nozzle main body 3.
Then, using Fig. 5 A, Fig. 5 B, Fig. 5 C, Fig. 5 D and Fig. 6, say to releasing the flow process of absorption of lens XA1
It is bright.Fig. 5 A are the sectional view of suction nozzle 2, represent and release to the state before the absorption of lens XA1.Fig. 5 B are the sectional view of suction nozzle 2,
Expression is carrying out spraying the state of step S100.Fig. 5 C are the sectional view of suction nozzle 2, represent and are carrying out negative pressure removal process
The state of S200.Fig. 5 D are the sectional view of suction nozzle 2, represent and are carrying out the state that suction nozzle keeps out of the way step S300.Fig. 6 is to releasing
The flow chart that the flow process of the absorption of lens XA1 is illustrated.
First, as shown in Figure 5A, the lens XA1 adsorbed by suction nozzle 2 is made to drop to mounting surface (omission reference) i.e.
By the height before abutting.
Then, malleation is produced by pump unit (omitting diagram), as shown in Figure 5 B, the multiple projection 17 kept out of the way is dashed forward from each
Go out opening 12 to project, and the gas being directed along multiple circumferential passages 8, spray (with reference in Fig. 6 from each circumferential openings 11
S100).Thus, absorption of the suction nozzle 2 to lens XA1 is released.
But, the gap (omission reference) or center of generation between top ends 3a and lens XA1 of suction nozzle main body 3
Negative pressure is also remained in passage 7.Therefore, in the case where quickly keeping out of the way suction nozzle 2, because top ends 3a in suction nozzle main body 3 with it is saturating
The negative pressure of residual in the gap produced between mirror XA1 or central passage 7, can again adsorb lens XA1.
Therefore, with spray step 100 simultaneously or behind, as shown in Figure 5 C, suction lentamente made with speed SP1 for specifying
Mouth 2 somewhat (for example, more than 50 μm and less than 100 μm) rises (with reference to the S200 in Fig. 6).Thus, extraneous gas flows into suction nozzle
In the gap produced between top ends 3a and lens XA1 of main body 3 or central passage 7.As a result, on the top of suction nozzle main body 3
The negative pressure of residual is eliminated (reset) in the gap produced between portion 3a and lens XA1 or central passage 7.
Then, as shown in Figure 5 D, make suction nozzle 2 and risen (in Fig. 6 with high speed SP2 more faster than speed SP1 for specifying
S300).Thus, suction nozzle 2 is kept out of the way.
In addition, here, so that suction nozzle 2 with specify speed SP1 lentamente rise, then, with high speed SP2 rise situation
As a example by be illustrated, but the invention is not restricted to this, it is also possible to spray step S200 after, after temporarily ceasing suction nozzle 2
Rise again.
Suction nozzle 2 from the description above, is passing through to attract gas to produce negative pressure, by negative-pressure adsorption lens XA1's
In the case of, due to making the central opening 10 of attraction gas relative with the center of lens XA1, enhance the power of absorption lens XA1.By
This, can reliably keep lens XA1.Further, high speed carrying can be carried out to the lens XA1 for adsorbing.Then, gas is being sprayed
And in the case of absorption of the releasing to lens XA1, gas does not spray from the central opening 10 relative with the center of lens XA1, and
Gas is sprayed from the circumferential openings 11 around the central opening 10, therefore, even if when dust is drawn into inside, also not
Dust can be sprayed at the center of lens XA1.Therefore, it is possible to prevent dust to be attached in lens XA1 in the heart.
Also, because pressure of the valve 4 by the gas for attracting or spraying carries out action, it is possible to by simple knot
Structure is realized.Further, since valve 4 has the compression face 13 of the pressure for bearing the gas for attracting or spraying, it is possible to by letter
Single structure is realized.
Further, due to projection 17, it is possible to being positioned on the lens XA1 of absorption using the pressing of projection 17
Ring XA2.Thus, prevent the gas that ring XA2 is ejected from blowing winged.
Also, because pressure of the projection 17 by the gas for attracting or spraying carries out action, it is possible to by simple
Structure realize.
Further, since when the absorption to lens XA1 is released, negative pressure removal process S200 is performed, so releasing to saturating
After the absorption of mirror XA1, it is prevented from the negative pressure by residuing in central passage 7 and adsorbs lens XA1 again.
