Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, the substrate is centered in the width direction in the pre-process of film pasting in the film pasting apparatus. And In addition, the present invention relates to a substrate width adjusting and reversing device adapted to reverse the front and back by 180 °.
[0002]
[Prior art]
There is a film sticking device for attaching a laminate film having a photosensitive resin layer to the surface of a substrate exemplified by a substrate for a printed wiring board, a glass substrate for a liquid crystal panel, and a substrate for a plasma display.
[0003]
Such a film sticking device is a device that transports a substrate by a substrate transport device, and pastes the laminate film on its upper surface so that its photosensitive resin layer faces, The substrate is cut continuously or according to the length of the substrate, and pasted together with the substrate by passing between a pair of rotating laminating rolls.
[0004]
In recent years, even in the case of printed circuit board circuits, pixels in liquid crystal panels and plasma displays with high definition and slight dust adhering to the substrate surface, if the film is pasted and the pattern is burned in the subsequent process, the dust etc. This causes a problem that the pixel in the portion where the toner adheres causes defective products.
[0005]
On the other hand, a film pasting method and apparatus have been proposed in which the film pasting surface of the substrate faces downward (lower surface) and the film is pasted on the lower surface from below.
[0006]
In this case, since the film tensioning surface cannot be brought into contact with the conveying roller or the like, the film tensioning surface is directed upward and conveyed to the vicinity of the laminating roll, where the substrate is separated from the surface opposite to the film tensioning surface. In the state where it is sucked and inverted 180 °, it is supplied as it is between the laminating rolls.
[0007]
[Problems to be solved by the invention]
By the way, when the substrate is fed between the laminating rolls, a so-called centering process called so-called width alignment is required in which the center position in the width direction of the substrate coincides with the center line of the laminating roll.
[0008]
A conventional substrate width adjusting device for centering is a substrate width adjustment device in which the substrate on the conveyance roller is lifted by a number of rollers that rotate in a direction perpendicular to the conveyance roller, and the width of the substrate is adjusted by a width alignment plate or the like. It is designed to be centered by pushing inward.
[0009]
Here, as described above, in the underlay type film sticking apparatus for sticking the film with the film sticking surface of the substrate facing downward, the lower side surface that is the opposite side of the film sticking surface is reversed when the substrate is reversed. Adsorption by the adsorption means and it is necessary to reverse 180 °, but it is very difficult to adsorb the substrate from the lower side in the vicinity of the substrate conveyance roller because the adsorption plate and the conveyance roller interfere with each other. In particular, in recent years, the size of the substrate has increased, and in order to adsorb the enlarged substrate, the suction plate must be made large, and interference with the transport roller is inevitable.
[0010]
Further, when the substrate is transported by the transport roller, when the substrate is large, the transport time becomes long and the efficiency of the apparatus is lowered. Therefore, recently, a substrate is carried in by a robot.
[0011]
On the other hand, since the film sticking apparatus must be capable of sticking a film corresponding to substrates of various widths, the suction plate must be smaller than the minimum size substrate.
[0012]
Therefore, in the case of the substrate of the maximum size, both ends of the substrate may be drooped greatly while being sucked by the suction plate. It is not possible to directly use a substrate width adjusting device placed on a flat plate.
[0013]
In addition, it is conceivable that the substrate is placed in a state where the substrate is placed on a horizontal suction plate, but in this case, since the suction plate area cannot be sufficiently increased as described above, the substrate of the maximum size is placed on the suction plate. There is an inconvenience of slipping off.
[0015]
This invention Substrate width reversal is possible to ensure that the substrates that are likely to sag at both ends in the width direction can be reliably shifted, and can be fed to the laminating roll without inverting the film by 180 ° and damaging the film tensioning surface. An object is to provide an apparatus.

The code | symbol 70 of FIG.10 and FIG.11 shows a film guide roll. When the film guide roll 70 is disposed in the vicinity of the entry side of the lower laminating roll 12 and is swung by a driving device (not shown) at a position indicated by a solid line in FIG. 10, the laminating roll 12A, The laminated film 52 is guided so that the laminated film 52 is not in contact with 12B, and when the laminated film 52 is swung to the position shown in FIG. 11, the laminated film 52 is wound around the lower laminating roll 12B. It is to be made.
[0068]
As shown in FIG. 12, the laminate film 52 is formed by laminating a photosensitive resin layer 52B on a translucent support film 52A and then covering it with a cover film 52C, as shown in FIG. Thus, the film roll 72 is wound and supplied to the lower laminating roll 12B through the tension roll group 74, the half cutter 76, the cover film peeling device 78, the suction roll 80, and the guide roll 82.

When the cover film 52C is cut, the film is synchronized with the laminate film 52. While traveling in the feeding direction, the disk cutters 76A and 76B are moved in the film width direction to perform a flying cut (cutting between runs) for cutting the cover film 52C.
[0072]
The distance between the pair of disk cutters 76A, 76B in the half cutter 76 in the film feeding direction is substantially equal to the distance between the substrates 18 fed between the laminating rolls 12A, 12B.
[0073]
The cover film peeling device 78 is composed of an adhesive tape roll 78A, a swing roll 78B, and a cover film take-up roll 78C, and the adhesive surface side of the adhesive tape 79 unwound from the adhesive tape roll 78 faces upward and outward. In addition, after being wound around the swing roll 78B, the cover roll is taken up by a cover film take-up roll 78C. The pressure-sensitive adhesive surface of the pressure-sensitive adhesive tape 79 is pressed against the cover film 52C by being pressed against the receiving roll 78E through the laminate film 52.
[0074]
Since the adhesive tape 79 is wound on the cover film take-up roll 78C while being adhered to the cover film 52C, the cover film 52C is peeled off from the photosensitive resin layer 52B, and the cover film take-up roll together with the adhesive tape 79. It is wound on 78C.
[0075]
The range in which the adhesive tape 79 is pressed against the cover film 52C by the swing mechanism 78D is other than the portion between the cutting lines formed by the pair of disk cutters 76A and 76B of the half cutter 76. The cover film 52C is peeled off leaving a portion.
[0076]
The laminate film 52 is peeled off by the cover film peeling device 78 as described above, leaving the portion between the substrates 18 and 18, and sent to the lower laminating roll 12B with the photosensitive resin layer 52B exposed. It is.

On the downstream side of the laminating rolls 12A and 12B and the laminate film feeding direction, the first nip roll 90, the transport roll 92, the second nip roll 94, and the rotary cutter 96 are arranged in this order from the laminating rolls 12A and 12B side. Is arranged in.
[0079]
The first nip roll 90 is composed of an upper roll 90A and a lower roll 90B, and the substrate 18 and the laminate film 52 attached thereto are sandwiched therebetween.
[0080]
The upper roll 90A is attached to the tip end of a substantially L-shaped swingable lever 91A, and is swingable to and from the lower roll 90B by swinging the lever 91A by an air cylinder 91B.
[0081]
The second nip roll 94 includes an upper roll 94A and a lower roll 94B. The upper roll 94A is a free roll that is rotatably supported at the tip of a lever 95B that is swingably supported by a shaft 95A, and the substrate 18 and the laminate film 52 are placed between the lower roll 94B and its own weight. It is made to pinch.
[0082]
Here, the upper roll 90A in the first nip roll 90 is from a motor (not shown) by a belt 98A, and the transport roll 92 and the lower roll 94B in the second nip fleur 94 are from a motor (not shown).

[0083]
The rotary cutter 96 includes a rotary blade 96A and a straight blade 96B. The rotary blade 96A has a configuration in which a cutting blade 96D is wound in a spiral or oblique straight line around a cylindrical member 96C arranged horizontally and in the substrate width direction, and the straight blade 96B has a central axis line of the cylindrical member 96C. It is arranged in a straight line that is long in the substrate width direction in parallel, and its tip contacts the rotation locus of the cutting blade of the rotary blade 96A on the passage locus of the laminate film 52 attached to the substrate 18. It has been made possible.
[0084]
As shown in FIG. 14, when the cutting edge 96D of the cylindrical member 96C is at a position lower than the passage surface of the laminated film 52, the laminated film 52 is above the cylindrical member 96C and is cut. It passes through the inside of a circular passage locus of the blade 96D.
[0085]
Therefore, when the cylindrical member 96C is rotated from this state, the laminate film 52 is cut between the cutting blade 96D and the straight blade 96B.
[0086]
Reference numeral 99 in FIG. 14 denotes a laminate film 52 that is disposed between the second nip roll 94 and the rotary cutter 96 and has passed through the second nip roll 94 or the substrate 18 to which the laminate film 52 is attached. The horizontal guide plate which guides so that it may pass horizontally through the rotary cutter 96 reliably is shown.

The swing lever 97 is swung by being driven up and down by an air cylinder 97B at the end opposite to the straight blade 96B.
[0090]
Here, the swing lever 97 is formed to be long in the substrate width direction, and an air blowing tube 100 is disposed at an upper position thereof, and the swing lever 97 is formed at an appropriate interval in the substrate width direction. The compressed air can be blown in the direction of the rotary blade 96A through the blow-through hole 97C.
[0091]
Accordingly, the laminate film 52 cut by the rotary blade 96A and the straight blade 96B is pushed downward or blown away by the compressed air blown from the air blowing tube 100 through the blow-through hole 97C.
[0092]
A cut piece receiver 102 that is long in the substrate width direction is disposed on the exit side and the lower side of the rotary blade 96A.
[0093]
The cutting receptacle 102 receives a cut piece of the laminated film 52 that has fallen by the inner tray 102A, and can be pulled out to the outer guide 102B. A cut piece of the body film 52 can be taken out.
[0094]
As shown in FIGS. 1 and 9, four optical sensors 50 </ b> A to 50 </ b> D are disposed in the vicinity of the substrate heating device 50.
[0095]
The optical sensor 50 </ b> A is arranged on the entrance side of the heating panel 51 and detects the front end and the rear end of the substrate 18 conveyed by the suction plate 36.
[0096]
As shown in FIG. 9, the optical sensor 50 </ b> B detects the substrate 18 when it reaches the vicinity of the laminating rolls 12 </ b> A and 12 </ b> B side ends of the heating panel 51. Further, the optical sensor 50C is located outside the support plate 58 for supporting the guide roll 54 in the substrate width direction, and is disposed at substantially the same position as the optical sensor 50B in the substrate feeding direction. It is configured to detect a moving table 44 that conveys.
[0097]
Further, the optical sensor 50D is arranged at the upper side of the entrance side of the laminating rolls 12A and 12B and at the center position in the substrate width direction, and detects the tip of the substrate 18 being conveyed.
[0098]
The output signals of these optical sensors 50A to 50D are input to the control device 32, and the control device 32 controls the substrate reversing device 16, the air cylinders 62, 68, 88, 91B and the like based on this signal. Details thereof will be described later.
[0099]
Next, the operation of the substrate width adjusting and reversing device 10 will be described.
[0100]
When the substrate 18 is carried into the substrate width adjusting device 14 in the substrate width adjusting and reversing device 10 by the robot hand unit 20, the suction plate 36 of the substrate reversing device 16 is moved to the substrate loading position as shown in FIG. The substrate 18 is moved to the center of the substrate 18 and is lowered by the lifting device 40 so as to be lower than the position of the substrate 18 as shown in FIG.
[0101]
Further, the roller support members 34A and 34B are driven by the air cylinder 28A as shown by a two-dot chain line in FIG. 5, and the substrate receiving rollers 22 in the substrate receiving roller group 24 are moved at both ends in the width direction of the loaded substrate 18. Keep the part in a position where it can be supported from below. In this state, the substrate 18 is carried into the upper part of the substrate receiving roller group 24 by the hand unit 20 and then lowered so that both ends in the width direction of the substrate 18 are supported from below by the substrate receiving roller group 24. The hand unit 20 is lowered and the substrate 18 is transferred to the substrate receiving roller group 24.
[0102]
When the substrate 18 is transported by the hand unit 20, the central portion in the width direction of the substrate 18 may hang down, but when the suction plate 36 carries the substrate 18 into the position of the substrate width adjusting device 14 by the hand unit 20. In addition, since the position is slightly lower than the substrate 18, the sag is lifted and corrected by the suction plate 36 immediately before being supported by the substrate receiving roller group 24.
[0103]
When the optical sensor 31 detects the substrate 18, the hand unit 20 is retracted by the control device 32, and the width adjusting member 26 is driven inward in the substrate width direction by the air cylinder 30 </ b> A and is supported from below by the substrate receiving roller group 24. The board | substrate 18 of the state currently made is brought near.
[0104]
At this time, since the rotation surface of the substrate receiving roller 22 coincides with the protruding direction of the width adjusting member 26, the substrate 18 is moved in the width direction without resistance.
[0105]
The protruding amount of the width adjusting member 26 is regulated by the length of the spacer 33. Further, when the width adjusting member 26 moves, the clearance groove 30C is formed on the lower side of the width adjusting member 26, so that it does not interfere with the substrate receiving roller 22.
[0106]
Immediately after the width adjustment by the substrate width adjusting device 14, the substrate receiving roller group 24 and the width adjusting member 26 are retracted to the outside of the frame 29 by the air cylinders 28A and 30A. After these retreats, the lifting plate 40 raises the suction plate 36 of the substrate reversing device 16.
[0107]
At this time, a negative pressure is applied in advance to the suction hole 36C of the suction surface, which is the upper surface of the suction plate 36, so that when the suction surface 36B comes into contact with the lower surface of the substrate 18, it can be sucked.
[0108]
When the suction plate 36 is raised to the position of the two-dot chain line shown in FIG. 2 and FIG. 6A by the lifting device 40, the rise is stopped, and at the same time, the rotary device 37 rotates the rotary shaft 36 </ b> A and the suction plate. 36 is rotated 180 ° so that the suction surface 36B of the suction plate 36 faces downward. In this state, as shown in FIG. 6B, the moving table 44 is moved in the direction of the laminating roll 12 by the moving device 46.
[0109]
The suction plate 36 is positioned between the pair of laminating rolls 12 and 12 when the suction surface 36B is inverted downward, so that the moving table 44 advances in the direction of the laminating roll 12. At this time, the substrate 18 adsorbed on the adsorbing surface 36B is interdigitated with the laminated film 52 between the pair of upper and lower laminating rolls 12A and 12B.
[0110]
However, since the substrate 18 adsorbed to the adsorption plate 36 is thin and larger than the adsorption plate 36, the outer peripheral portion of the substrate 18 hangs down and can be caught between the pair of laminating rolls 12A and 12B. Can not.
[0111]
Therefore, when the front end of the substrate 18 is detected by the optical sensor 50A, the moving table 44 is stopped, and in this state, the support bar 56 and the guide roller 54 supported by the air cylinder 62 are illustrated. 9. As shown in FIG. 10, the moving base 44 is moved in the direction of the laminating rolls 12A and 12B by waiting at a position below the passage surface of the substrate 18. When the front end of the substrate 18 is detected by the optical sensor 50B, the moving table 44 is stopped, and then the guide roller 54 is raised so that both ends of the substrate 18 in the width direction are high between the pair of laminating rolls 12A and 12B. Lift it up and correct.
[0112]
Prior to this, the film guide roll 70 was driven counterclockwise from the position of the solid line in FIG. 10 to the position of the two-dot chain line or the position shown in FIG. The air blowing member 64 is advanced from the state shown in FIG. 10 to the position shown in FIG. 11 by the air cylinder 68, and compressed air flows from the concave curved surface 64A at the tip thereof. Etc. are jetted to bring the laminate film 52 into close contact with the laminating roll 12B and to cool it uniformly in the width direction.
[0113]
At this time, as shown in FIG. 11, the guide roller 64 </ b> B attached to the gas blowing member 64 is at a position slightly equidistant from the upper end surface of the guide roller 54 at a position equal to the guide roller 54. It is said.
[0114]
The substrate 18 whose both ends in the width direction are horizontally lifted by the guide roller 64B is transported horizontally in the direction of the laminating rolls 12A and 12B by re-driving the movable table 44.
[0115]
At this time, the front end of the substrate 18 in the advancing direction slightly hangs down, but the guide roller 64B attached to the gas blowing member 64 is at a position slightly lower than the guide roller 54. The tip of 18 rides smoothly on the guide roller 64B and is fed between the pair of laminating rolls 12A and 12B while remaining in a horizontal state.
[0116]
The traveling speed of the moving table 44 in the direction of the laminating roll 12 is synchronized with the feeding speed of the substrate 18 by the laminating rolls 12A and 12B.
[0117]
The laminating rolls 12A and 12B are always rotated in a heated state, and while the substrate 18 is not transported, the upper laminating roll 12A is moved downward by the swing lever 84. Although it is in an “open” state separated from the roll 12B, the front end of the substrate 18 being conveyed is detected by the optical sensor 50D, and then the front end of the substrate 18 is the contact position of the laminating rolls 12A and 12B. The control device 32 drives the swing lever 84 through the air cylinder 88 at the timing when the upper laminating roll 12A is positioned between the laminating roll 12B and the leading end of the substrate 18 that has been loaded. It is made to pinch.
[0118]
The suction of the substrate 18 by the suction surface 36B of the suction plate 36 is maintained until the substrate 18 is bitten by the laminating rolls 12A and 12B to a certain extent, whereby the centering of the substrate 18 is ensured. When the moving table 44 is detected, the negative pressure on the suction surface 36B is released.
[0119]
After the substrate 18 is released, the suction plate 36 is returned to the position indicated by the solid line in FIG. 6A by the moving device 46, is reversed again, and waits until the next substrate is loaded with the suction surface 36B facing upward. The
[0120]
Next, the substrate 18 carried in by the robot's hand unit 20 is immediately brought in the same manner as described above, and then sucked and reversed by the suction plate 36 and is put on standby in front of the substrate heating device 50.
[0121]
When the preceding substrate 18 is sandwiched and conveyed by the laminating rolls 12A and 12B and the rear end of the substrate 18 is detected by the optical sensor 50, the position of the substrate heating device 50 by the moving device 46 of the next substrate 18 is detected. Carrying in is started.
[0122]
The laminate film 52 fed between the laminating rolls 12A and 12B together with the substrate 18 and attached to the substrate 18 is unwound from the film roll 72 as described above, and then covered by the disk cutters 76A and 76B. The film 52C is cut in the width direction at a predetermined position, and then the cover film 52C is peeled off by the cover film peeling device 78 as far as it is attached to the substrate 18, and the laminating is performed with the photosensitive resin layer 52B exposed. Supplied to the roll 12B.
[0123]
Note that the leading end of the laminate film 52 does not come into contact with the rotating laminating rolls 12A and 12B through the film guide roll 70 before the top substrate 18 is fed between the laminating rolls 12A and 12B. In this state, the first and second nip rolls 90 and 94 are sandwiched and set.
[0124]
Of the substrates 18 that are sequentially carried in, the laminate film 52 is not required until the top substrate 18 reaches the position of the rotary cutter 96. Disconnected and processed.
[0125]
More specifically, the laminate film is fed in the right direction in FIG. 14 together with the substrate 18 until the leading end of the first substrate 18 with the laminate film 52 attached has reached the position of the rotary cutter 96. On the other hand, when the rotary blade 96A of the rotary cutter 96 is rotated clockwise at a constant speed, the laminate film 52 is moved from the tip by a predetermined length each time the cutting blade 96D at the tip of the rotary blade 96A comes into contact with the straight blade 96B. It will be cut off.
[0126]
The front end portion of the cut laminate film 52 is conveyed rightward in FIG. 13 by the cutting blade 96D, but from the rotary blade 96A by the compressed air flow blown from the air blowing tube 100 through the blow-through hole 97C. It is shaken off, and falls sequentially onto the tray 102A of the cut piece receptacle 102 and is collected.
[0127]
The rotary cutter 96 is cut by swinging the linear blade 96B via the swing lever 97 by the air cylinder 97B each time the laminated film 52 reaches between the substrates after the leading substrate 18. In addition, after cutting, the straight blade 96B is swung clockwise in FIG. 14 so as not to interfere with the substrate 18, and is ready for the next cutting.
[0128]
As described above, the substrate 18 conveyed by the hand unit 20 of the robot is width-adjusted by the substrate width aligning device 14, reversed by the substrate reversing device 16, and a laminate film between the laminating rolls 12A and 12B. 52, the photosensitive resin layer 52 </ b> B exposed by peeling the cover film 52 </ b> C in the laminate film 52 is attached to the substrate 18, and then the laminate film 52 is cut between the substrates by the rotary cutter 96. Thus, the substrate 18 in a state where the laminate film 52 is stuck is formed.
[0129]
The suction plate 36 in the substrate width-shifting reversing device 10 is configured so that it can be turned 180 ° around the rotation shaft 36A. However, the present invention is not limited to this, and for example, a suction plate is used. The substrate may be reversed by attaching to the tip of the reversing arm and rotating the reversing arm 180 °.
[0130]
