[action specification]
Then, the action to silk-screen printing device 100 describes.
Fig. 7 illustrates the side view that utilizes the situation of scraper mechanism when substrate 1 printing paste scolder 2.Fig. 8 illustrates the side enlarged drawing that utilizes the situation of scraper mechanism when substrate 1 printing paste scolder 2.
At first, substrate 1 touches the downside of silk screen 3 by location division 20.Then, drive cylinder 18, make the 1st scraper mechanism 11 move (with reference to Fig. 7 (A) dotted line) downwards.When the 1st scraper mechanism 11 moved downwards, the leading section of scraper 13 was with the pressure butt silk screen 3 of regulation.On silk screen 3, supply with paste scolder 2 by scolder supply unit (not shown).
Then, 11 beginnings of the 1st scraper mechanism are moved (with reference to Fig. 7 (A) solid line) towards glide direction.When the 1st scraper mechanism 11 begins to move, apply voltage to the 1st piezoelectric element portion and the 2nd 72b of piezoelectric element portion, the 1st jolting plate 71a of the 1st scraper mechanism 11 and the 2nd jolting plate 71b begin vibrations.
The 1st scraper mechanism 11 is when glide direction moves, and scraper 13 slides at silk screen 3.At this moment, Yi Bian on one side giving 2 vibrations of paste scolder at the front side of the glide direction of scraper 13, the 1st jolting plate 71a makes 2 lift-over of paste scolder.Because of the 1st jolting plate 71a surface liquid stateization, thus, formed the liquid stateization layer on lift-over scolder 2a surface by the paste scolder 2 of lift-over (lift-over scolder 2a).
The 1st jolting plate 71a shakes with suitable vibration frequency (for example, more than the 50Hz) and amplitude (for example, more than the 20 μ m), thereby prevents that the shock transfer of the 1st jolting plate 71a from arriving scraper 13, and, can suitably form the liquid stateization layer.
And the leading section of the 2nd jolting plate 71b that lift-over scolder 2a is shaken is stirred to till the inner dark zone.Thus, can further make the liquid state layer thickening on the surface of lift-over scolder 2a.The 2nd jolting plate 71b shakes with suitable vibration frequency (for example, more than the 50Hz) and amplitude (for example, more than the 20 μ m), thereby prevents that the shock transfer of the 2nd jolting plate 71b from arriving scraper 13, and, can suitably stir lift-over scolder 2a.
A part that is formed on the liquid state layer on lift-over scolder 2a surface is utilized the leading section of the 2nd jolting plate 71b to scrape and is cut.Thus, near the leading section of the 2nd jolting plate 71b, form the portion that accumulates of the paste scolder 2 of liquid stateization.Like this, the part of liquid stateization layer is utilized the leading section of the 2nd jolting plate 71b to scrape and is cut, thereby can be made as the lift-over diameter of lift-over scolder 2a fixing.

＜the 2 embodiment 〉
Then, the 2nd embodiment to present technique describes.In the later explanation of the 2nd embodiment, to having the parts mark same-sign with the same function of the 1st above-mentioned embodiment and structure, and omission or simplified illustration.
Fig. 9 is the stereogram that the scraper mechanism of the 2nd embodiment is shown.Figure 10 is the vertical view that scraper mechanism is shown.
This scraper mechanism disposes on guider portion 90 these aspects different with the 1st above-mentioned embodiment in the both ends side of the width (with the direction of glide direction quadrature) of scraper 13 (and vibrations portion 70).Other point is identical with the 1st above-mentioned embodiment.
In the outside of the 1st guider 90a and the 2nd guider 90b, be respectively equipped with the 3rd piezoelectric element portion 93.The 3rd piezoelectric element portion 93 for example is configured in the position corresponding with the position that is formed with lift-over scolder 2a.
The 3rd piezoelectric element portion 93 is electrically connected with control part 60, according to the control vibration frequency vibrations in accordance with regulations of control part 60.Thus, the 1st guider 90a and the 2nd guider 90b vibration frequency and the vibrations of amplitude broad ways in accordance with regulations.The vibration frequency of the 3rd piezoelectric element portion 93 vibrations can with the 1st 72a of piezoelectric element portion and the 2nd 72b of piezoelectric element portion is identical also can be different.
The 3rd piezoelectric element portion 93 for example also can be covered by not shown cover.Thus, can prevent that paste scolder 2 is attached to the 3rd piezoelectric element portion 93.
The 1st guider 90a and the 2nd guider 90b are installed to scraper holding member 14 via the 5th vibrations insulating materials 94 respectively.Thus, can prevent that the shock transfer of the 1st guider 90a and the 2nd guider 90b is to scraper 13.The 1st guider 90a and the 2nd guider 90b do not contact with scraper 13 and vibrations portion 70, form gap 95 between the 1st guider 90a and the 2nd guider 90b and scraper 13 and vibrations portion 70.The rear side that scraper mechanism 11,12 constitutes at scraper 13 makes the part of paste scolder 2 become separated in flight via this gap 95.
The 1st guider 90a and the 2nd guider 90b also can implement the low friction processing of paste scolder 2 on its surface or hang down and adhere to processing (perhaps these combination).
[action specification]
Then, the action to the silk-screen printing device 100 of the 2nd embodiment describes.

The 1st guider 90a and the 2nd guider 90b support lift-over scolder 2a preventing the transverse leakage of paste scolder 2 from the side, and, give lift-over scolder 2a vibrations.Like this, by from the side lift-over scolder 2a being shaken, can be suppressed at the lift-over velocity deviation of the lift-over scolder 2a of width (X-direction).
Namely, in order to prevent the transverse leakage of scolder, disposed under the situation of the 1st guider 90a and the 2nd guider 90b in the both ends side of the width of scraper 13, the both end sides of the width of lift-over scolder 2a is supported by the 1st guider 90a and the 2nd guider 90b.Adopt the support of the lift-over scolder 2a of this guider to become the lift-over resistance of lift-over scolder 2a, can produce deviation at width in the lift-over speed of lift-over scolder 2a.For example, lift-over speed is very fast relatively near the central authorities of the width of lift-over scolder 2a, and sidewinder rotary speed at the both ends of the width of lift-over scolder 2a relatively slow.Thus, 2 pairs in the paste scolder filling quality that is located at the pattern hole 4 of silk screen 3 might descend.
On the other hand, as mentioned above, the 1st guider 90a and the vibrations of the 2nd guider 90b broad ways, thereby can reduce above-mentioned lift-over resistance.Therefore, can be suppressed at the lift-over velocity deviation of the lift-over scolder 2a of width (X-direction).Thus, can suppress the reduction of filling quality that 2 pairs in paste scolder is located at the pattern hole 4 of silk screen 3.
The 1st scraper mechanism 11 is when glide direction moves, and the part of paste scolder 2 is become separated in flight to the rear side of scraper 13 via above-mentioned gap 95, and residues on the silk screen 3.
In the time of near the end of the 1st scraper mechanism 11 arrival silk screens 3, the 1st scraper mechanism 11 is moved upward, and the 2nd scraper mechanism 12 moves (with reference to Fig. 7 (B) dotted line) downwards.
Be moved upward and when scraper 13 separated from silk screen 3, the 1st guider 90a and the 2nd guider 90b also can shake in the 1st scraper mechanism 11.Thus, can prevent that paste scolder 2 is attached to the 1st guider 90a portion and the 2nd guider 90b portion.
When the scraper 13 of mobile and the 2nd scraper mechanism 12 was with substrate 1 butt downwards, then, 12 beginnings of the 2nd scraper mechanism were moved (with reference to Fig. 7 (B) solid line) towards glide direction in the 2nd scraper mechanism 12.
When the 2nd scraper mechanism 12 moves, become separated in flight from the gap of the 1st scraper mechanism 11 and the leading section (crooked part) of paste scolder 2 by the 1st guider 90a and the 2nd guider 90b that remain on the silk screen 3 is recovered before.After, alternately carry out repeatedly based on the printing of the 1st scraper mechanism 11 with based on the printing of the 2nd scraper mechanism 12.
