Then, use Fig. 2 A, Fig. 2 B and Fig. 3, the structure of suction nozzle 2 is described.Fig. 2 A is the sectional view of suction nozzle 2, when representing attraction gas.Fig. 2 B is the sectional view of suction nozzle 2, when representing ejection gas.Fig. 3 is the upward view of suction nozzle 2.
As shown in Fig. 2 A, Fig. 2 B and Fig. 3, suction nozzle 2 has suction nozzle main body 3, valve 4, multiple (being 3 in the present embodiment) pressing member 5.
Cardinal extremity passage 6, central passage 7, multiple (being 3 in the present embodiment) circumferential passages 8, pressing member spatial accommodation 9 etc. is formed in suction nozzle main body 3.
Cardinal extremity passage 6, is set to the central authorities of longitudinally running through the base end side (upside in Fig. 2 A and Fig. 2 B, the inner side in Fig. 3) of suction nozzle main body 3, and is connected with central passage 7, multiple circumferential passages 8 and multiple pressing member spatial accommodation 9.This cardinal extremity passage 6, guides to pump unit (omitting diagram) by the gas of attraction from circumferential passages 8, on the other hand, is guided by the gas of ejection from pump unit to central passage 7 and multiple circumferential passages 8.
Central passage 7, is set to the central authorities of longitudinally running through the tip side (downside in Fig. 2 A and Fig. 2 B, the side, front in Fig. 3) of suction nozzle main body 3, and is connected with central opening 10 by cardinal extremity passage 6.This central passage 7, guides to cardinal extremity passage 6 by the gas of attraction from central opening 10, on the other hand, does not guide the gas of ejection.
Multiple circumferential passages 8, is set to respectively and longitudinally runs through being arranged in tip side (downside of Fig. 2 A and Fig. 2 B, the side, front in Fig. 3) and being positioned at the position of the surrounding of central passage 7 of suction nozzle main body 3, be connected by cardinal extremity passage 6 with circumferential openings 11.These multiple circumferential passages 8, guide to cardinal extremity passage 6 by the gas of attraction from circumferential openings 11 respectively, on the other hand, the gas of ejection are guided to circumferential openings 11 from cardinal extremity passage 6.
Multiple pressing member spatial accommodation 9, what be set to longitudinal through suction nozzle main body 3 respectively is arranged in the tip side (downside of Fig. 2 A and Fig. 2 B, side, front in Fig. 3) and be positioned at the position of the surrounding of central passage 7, connected with outstanding opening 12 by cardinal extremity passage 6, multiple pressing member spatial accommodation 9 alternately configures around central passage 7 with multiple circumferential passages 8.These multiple pressing member spatial accommodations 9, have 2 Rotating fields, wherein respectively, base end side (the upside in Fig. 2 A and Fig. 2 B, inner side in Fig. 3) diameter relatively large, the diameter of tip side (downside in Fig. 2 A and Fig. 2 B, the side, front in Fig. 3) is relatively little.Further, multiple pressing member spatial accommodation 9 holds pressing member 5 with the state making pressing member 5 can move back and forth on above-below direction (above-below direction in Fig. 2 A and Fig. 2 B, the inside in Fig. 3 and the direction of front) respectively.
In addition, central opening 10, multiple circumferential openings 11 and multiple outstanding opening 12, lay respectively at the top ends 3a of suction nozzle main body 3.
Valve 4, with the state that can move back and forth on above-below direction (above-below direction in Fig. 2 A and Fig. 2 B, the inside in Fig. 3 and the direction of front), is located at the coupling part of cardinal extremity passage 6 and central passage 7.Specifically, valve 4 comprises bearing and attracts or the compression face 13 of pressure (pressure of the gas in cardinal extremity passage 6) of gas of ejection and the flange 14 that arranges around this compression face 13.
The upper surface of compression face 13 is relative with cardinal extremity passage 6, and the lower surface of compression face 13 is relative with central passage 7, multiple circumferential passages 8 and multiple pressing member spatial accommodation 9.On this compression face 13, each position relative with multiple circumferential passages 8 is formed with passage 15, and is formed with patchhole 16 on each position relative with multiple pressing member spatial accommodation 9.
Flange 14 always forms space between compression face 13 and cardinal extremity passage 6, is blocked by cardinal extremity passage 6 to prevent compression face 13.
Such valve 4, born the pressure (pressure of the gas in cardinal extremity passage 6) of the gas attracted or spray by compression face 13, the pressure by this gas carries out action.
I.e., when attracting gas (with reference to Fig. 2 A), valve 4 by the gas in cardinal extremity passage 6 pressure (negative pressure) and rise, by passage 15, cardinal extremity passage 6 and central passage 7 are interconnected, allow to attract gas from central opening 10.Now, cardinal extremity passage 6 and multiple circumferential passages 8 are interconnected by passage 15, allow to attract gas from multiple circumferential openings 11.
On the other hand, when spraying gas (with reference to Fig. 2 B), valve 4 declines due to the pressure (malleation) of the gas in deadweight or cardinal extremity passage 6, compression face 13 is utilized to block central passage 7, cardinal extremity passage 6 and central passage 7 are disconnected mutually, to refuse to spray gas from central opening 10.Now, cardinal extremity passage 6 and multiple circumferential passages 8, be interconnected by passage 15, allows to spray gas from multiple circumferential openings 11.
Multiple pressing member 5, respectively with the state that can move back and forth on above-below direction (the upper direction in Fig. 2 A and Fig. 2 B, the inside in Fig. 3 and the direction of front), is located in pressing member spatial accommodation 9.These multiple pressing members 5 have 2 Rotating fields respectively, wherein, the diameter of base end side (upside in Fig. 2 A and Fig. 2 B, the inner side in Fig. 3) is relatively large, the diameter of tip side (downside in Fig. 2 A and Fig. 2 B, the side, front in Fig. 3) is relatively little.
Further, the diameter of the base end side of multiple pressing member 5, more smaller than the diameter of the base end side of pressing member spatial accommodation 9 respectively, and larger than the diameter of the tip side of pressing member spatial accommodation 9.In addition, the diameter of the tip side of multiple pressing member 5, more smaller than the diameter of the tip side of pressing member spatial accommodation 9 respectively.
Multiple pressing members 5 like this, play function respectively as the projection 17 outstanding from outstanding opening 12.I.e., when attracting gas (with reference to Fig. 2 A), multiple pressing member 5 respectively by the gas in cardinal extremity passage 6 pressure (negative pressure) and rise, projection 17 is retracted from outstanding opening 12.On the other hand, when spraying gas (with reference to Fig. 2 B), multiple pressing member 5 respectively by the gas in deadweight or cardinal extremity passage 6 pressure (malleation) and decline, projection 17 is given prominence to from outstanding opening 12.
And, base end side (the upside in Fig. 2 A and Fig. 2 B of the pressing member 5 declined, inner side in Fig. 3) the relatively large part of diameter, block the part that the diameter of the tip side (downside in Fig. 2 A and Fig. 2 B, the side, front in Fig. 3) in pressing member spatial accommodation 9 is relatively little.Thereby, it is possible to prevent gas from being sprayed from outstanding opening 12 by pressing member spatial accommodation 9.
Like this, attract or the pressure of gas (gas in cardinal extremity passage 6) of ejection by being born by the cardinal extremity (omission Reference numeral) of pressing member 5, projection 17 by this gas pressure and carry out action.And, when spraying gas (with reference to Fig. 2 B), projection 17 becomes from the outstanding state of the top ends 3a of suction nozzle main body 3, on the other hand, when attracting gas (with reference to Fig. 2 A), projection 17 becomes the state of keeping out of the way from the top ends 3a of suction nozzle main body 3.
Then, use Fig. 4 A and Fig. 4 B, the flow process of absorption lens XA1 is described.Fig. 4 A is the sectional view of suction nozzle 2, represents the state before absorption lens XA1.Fig. 4 B is the sectional view of suction nozzle 2, represents the state after absorption lens XA1.In addition, on the lens XA1 adsorbed by suction nozzle 2, the ring XA2 of these lens XA1 with band is placed with.
First, as shown in Figure 4 A, the top ends 3a of suction nozzle main body 3 is made to drop to lens XA1 by the height abutted.Thus, central opening 10 is relative with the approximate centre of lens XA1.Further, multiple circumferential openings 11 is relative with the flange portion (omission Reference numeral) of the surrounding being positioned at lens XA1 respectively.In addition, respectively relative with the ring XA2 be placed on lens XA1 respectively from multiple projections 17 that outstanding opening 12 is outstanding.
Then, produce negative pressure by pump unit (omitting diagram), as shown in Figure 4 B, outstanding multiple projections 17 are kept out of the way in each outstanding opening 12, and attract gas from central opening 10 and multiple circumferential openings 11.The gas attracted from central opening 10 is directed along central passage 7.The gas attracted from multiple circumferential openings 11 is directed along each circumferential passages 8.Thus, produce negative pressure being formed at the space between the top ends 3a of suction nozzle main body 3 and lens XA1 (omission Reference numeral), by this negative pressure, lens XA1 is adsorbed in the top ends 3a of suction nozzle main body 3.
Then, use Fig. 5 A, Fig. 5 B, Fig. 5 C, Fig. 5 D and Fig. 6, the flow process of the absorption removing lens XA1 is described.Fig. 5 A is the sectional view of suction nozzle 2, represents the state before removing the absorption of lens XA1.Fig. 5 B is the sectional view of suction nozzle 2, represents the state performing ejection step S100.Fig. 5 C is the sectional view of suction nozzle 2, represents the state performing negative pressure removal process S200.Fig. 5 D is the sectional view of suction nozzle 2, represents the state performing suction nozzle and keeping out of the way step S300.Fig. 6 is to removing the flow chart be described the flow process of the absorption of lens XA1.
First, as shown in Figure 5A, make the lens XA1 adsorbed by suction nozzle 2 drop to mounting surface (omission Reference numeral) be about to abut before height.
Then, produce malleation by pump unit (omitting diagram), as shown in Figure 5 B, multiple projection 17 of keeping out of the way is given prominence to from each outstanding opening 12, and along the gas that multiple circumferential passages 8 is directed, spray (S100 with reference to Fig. 6) from each circumferential openings 11.Thus, the absorption of suction nozzle 2 couples of lens XA1 is removed.
But, in the gap (omission Reference numeral) produced between the top ends 3a of suction nozzle main body 3 and lens XA1 or central passage 7, also remain negative pressure.Therefore, when making suction nozzle 2 keep out of the way fast, because of negative pressure residual in the gap that produces between the top ends 3a and lens XA1 of suction nozzle main body 3 or central passage 7, again lens XA1 can be adsorbed.
Therefore, with ejection step 100 simultaneously or thereafter, as shown in Figure 5 C, suction nozzle 2 (such as, more than 50 μm and less than 100 μm) rising (S200 in reference Fig. 6) is a little made lentamente with the speed SP1 specified.Thus, extraneous gas flows in the gap or central passage 7 produced between the top ends 3a of suction nozzle main body 3 and lens XA1.As a result, negative pressure residual in the gap produced between the top ends 3a and lens XA1 of suction nozzle main body 3 or central passage 7 is eliminated (reset).
Then, as shown in Figure 5 D, make suction nozzle 2 with high speed SP2 rising (S300 in Fig. 6) faster of the speed SP1 than regulation.Thus, suction nozzle 2 is kept out of the way.
In addition, at this, to make suction nozzle 2 rise lentamente with the speed SP1 of regulation, then, be illustrated for the situation that high speed SP2 rises, but the present invention is not limited thereto, also after ejection step S200, can rise again after suction nozzle 2 is temporarily stopped.
According to suction nozzle 2 described above, by attracting gas to produce negative pressure, when by these negative-pressure adsorption lens XA1, owing to making the central opening 10 of attraction gas relative with the center of lens XA1, enhance the power of absorption lens XA1.Thereby, it is possible to reliably keep lens XA1.And then, high speed carrying can be carried out to the lens XA1 of absorption.Then, when spraying gas and remove the absorption to lens XA1, gas does not spray from the central opening 10 relative with the center of lens XA1, and spray gas from the circumferential openings 11 of the surrounding being positioned at this central opening 10, therefore, even if when dust is drawn into inside, also dust can not be sprayed at the center of lens XA1.Therefore, it is possible to prevent dust to be attached in lens XA1 in the heart.
Further, because valve 4 is by attract or the pressure of gas of ejection carries out action, so can be realized by simple structure.In addition, because valve 4 has the compression face 13 of the pressure bearing the gas attracted or spray, so can be realized by simple structure.
Further, owing to having projection 17, so the ring XA2 on the lens XA1 that projection 17 can be utilized to press be positioned in absorption.Thus, the gas that anti-stop ring XA2 is ejected blows and flies.
Further, because projection 17 is by attract or the pressure of gas of ejection carries out action, so can be realized by simple structure.
In addition, due to when removing the absorption to lens XA1, perform negative pressure removal process S200, so after removing the absorption to lens XA1, can prevent the negative pressure by residuing in central passage 7 from again adsorbing lens XA1.
Then, use Fig. 7 A and Fig. 7 B, the structure of the suction nozzle 22 of other embodiments is described.Fig. 7 A is the sectional view of suction nozzle 22, when representing attraction gas.Fig. 7 B is the sectional view of suction nozzle 22, when representing ejection gas.In addition, at this, only the characteristic of suction nozzle 22 is described, about the explanation of the same structure of the suction nozzle 2 with above-mentioned embodiment, effect, suitably omits.
