Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for supplying a film to a film sticking device for sticking a film on the surface of a substrate for printed wiring or the like.

[0002]

2. Description of the Related Art A photosensitive resin layer is formed on a translucent support film (base film; usually a resin film typified by polyester) in the process of manufacturing a printed wiring board used in electronic devices such as computers. The cover film is peeled off and the laminated film covered with the cover film is attached to the conductive layer on the surface of the printed wiring board. After that, a wiring pattern film is overlaid, and the photosensitive resin layer is exposed for a predetermined time through the wiring pattern film and the translucent support film. Next, after peeling the light-transmitting support film, the exposed photosensitive resin layer is developed to form an etching mask pattern, and thereafter, unnecessary portions of the conductive layer are removed by etching, whereby a predetermined portion is formed. A printed wiring board having the wiring pattern is formed.

A film sticking device for sticking a laminate film as described above, a continuous film (original film) loaded in a film supply roll, to the front end of a substrate conveyed by a conveying means, The photosensitive resin layer is guided so as to be on the side of the substrate, and is temporarily attached to the front end of the substrate by a temporary attaching means that can move toward and away from the substrate, and then a lamination roll is used to press the film onto the substrate, It is designed to convey a substrate.

[0004] The pressure bonding of the film to the substrate is carried out so that the bonding length becomes a length substantially corresponding to the length of the substrate, and the supply film is provided with the film temporary bonding means itself or a member in the vicinity thereof so as to have the length. It is cut by the film cutting means provided in. The cover film is peeled off before or after the tacking means.

As another film sticking device, the photosensitive resin layer side of the film, in which the cover film has been peeled off in advance, is continuously carried and stuck to the film sticking surface of the substrate which is intermittently carried. After that, there is also one called continuous tensioning in which a film is cut between adjacent substrates.

The laminated film as described above is unrolled and supplied from a film supply roll. However, since the winding length of the film supply roll is finite, the film is naturally used by using a fixed amount. The supply roll must be replaced. Also, when the remaining amount of film becomes extremely small, or when it is necessary to change the type and brand of film supplied to the film sticking device body according to the application, the film supply roll should be replaced with a new one. Need to supply film.

In this case, the core around which the original film is wound is removed together with the remaining original film, and a new film supply roll is loaded.

Conventionally, in this replacement, when it is time to replace the preceding film supply roll, the film sticking device is stopped, the preceding film supply roll is removed, and the leading end of the film drawn from the new film supply roll is
It was necessary to manually set the film separating member, the tension roller, the rollers of the film supply path, and the position of the lamination roll.

Therefore, conventionally, for example, it is necessary to replace the upper and lower film supply rolls which have been rewound in 2 hours.
It takes 0 minutes, and the so-called setup time occupies a very large proportion to the actual operation time, which not only lowers the operation rate of the film sticking apparatus but also lowers the efficiency of the entire line.

On the other hand, there is a film roll unit for a film sticking device, which is designed to exchange the film in a short time, as disclosed in Japanese Utility Model Laid-Open No. 3-15131. The roll, the cover film take-up roll and the guide roll are unitized and replaced at the same time, and the step of manually setting the leading end of a new film cannot be omitted. Also, it cannot be applied when the weight of the film roll is large.

Here, in recent years, the circuit density of a substrate such as a printed wiring has been improved, and even if a small amount of dust or the like adheres to the substrate or the film, it becomes a defective product. Therefore, the film is placed in a clean space, for example, a clean room. It is becoming more common to install auxiliary equipment and operate it here.

In the conventional film sticking apparatus, it is necessary to set the film each time the film supply roll is replaced, and dust is liable to be generated during this work. Therefore, when operating in a clean room, the setting is completed. After that, the device cannot be operated until the dust is reduced, which is inefficient.

On the other hand, although not known, the film supply roll can be replaced without stopping the operation of the apparatus, and the trailing end of the leading original film and the leading end of the trailing original film can be replaced. There has been proposed a method and an apparatus for continuously supplying a raw film in a film sticking apparatus capable of automatically connecting with the film.

In this method, the trailing edge of the leading material film and the leading edge of the trailing material film are cut and aligned, and their connecting lines are covered with an adhesive tape for connection.

[0015]

In this case, the cover film must be peeled off on the way and taken up by a take-up roll. The winding roll has a finite maximum winding diameter, and when the winding amount reaches a certain value and a new winding roll is replaced, the operation of the device must be stopped. As in the case of replacing the film supply roll, there is a problem that the operating rate of the apparatus and the efficiency of the entire line are reduced.

The present invention has been made in view of the above-mentioned conventional problems, and the operation of the apparatus is stopped even when the leading end of the trailing original film is connected to the trailing end of the preceding original film. The cover film is continuously and automatically peeled off and wound up, and when the winding amount of this cover film take-up roll exceeds a certain value, a new winding is performed without stopping the operation of the device. An object of the present invention is to provide a film supply method and device which can be replaced with a take-up roll.

The inclined guide surface 32B is the inclined surface 4 of the winding core recovery unit 44.
When the spindle 52 is pulled out from the preceding film supply roll 14 while being set at a guide position continuous with 4A,
The winding core 14A and the remaining film 12 slightly wound around it fall. Therefore, the winding core 14A released from the spindle 52 is guided along the inclined guide surface 32B and the inclined surface 44A and falls into the winding core collecting portion 44.

At this time, if the negative pressure only on the suction surface 24B side is released, when the winding core 14A falls, the end cutter 62 is released.
The leading end of the film 12 cut on the side of the film supply roll 14 is the lower suction surface 24 of the first suction device 24.
It is peeled from B (see FIG. 17).

Then, the guide plate 32 is returned to the position shown by the solid line in FIG.
18 is extruded to the left as shown in FIG. 18 so that the center of the trailing film supply roll 40 becomes the film supply roll center position in the set position.

At this time, the upper half of the adhesive surface 56B of the one-sided adhesive tape 56 adsorbed by the second adsorption device 46 is

When is started to move, counting of the film feed amount is started (S102).

One of the front and rear peel rollers 90 and 92 is in contact with the cover film 12C by the peel roller driving device 94, which is the control device 104.
The control device 104 detects that the connection line has approached the front or rear peel roller 90 or 92 on the side not in contact with the cover film 12C.
It is detected by the output signal from the rotary encoder 67 (S103).

For example, assuming that the front peel roller 90 is in contact with the cover film 12C of the leading original film, when the connection line of the film approaches the rear peel roller 92, the driving roll 110B and the rear winding The roll 100B is turned on, and the rear peel roller 92 is driven upward by the air cylinder 94D via the lever 94B (S104).

At this time, at the same time, the backup device 102
The rear backup roller 102B in FIG. 6 is driven by swinging the balance lever 102D by an air cylinder (S104), and the rear peel roller 9 in the contact position.
2 and the rear backup roller 102B are sandwiched by about 5 mm in front of the connection line of the film 12. On the other hand, the air cylinder 94C is driven to drive the front peel roller 90 to the retracted position.

As a result, the front peel roller 90 is located below the front sliding member 106A, so that even if the film 12C hangs down a little, the film 12 is wound around the front peel roller 90 on the single-sided adhesive tape 96.
It is prevented that the film comes into contact with and sticks.

As described above, the film 12 is sandwiched between the rear peel roller 92 and the rear backup roller 102B together with the single-sided adhesive tape 96. At this time, the rear peel roller 92 is separated from the rear backup roller. 1
02B is behind the film path 13 (to the right in the figure)
The single-sided adhesive tape 96 and the film 12 are sandwiched in a state in which they are slightly displaced.

The one-sided adhesive tape 96 is the drive roll 11
When the connecting line of the film 12 wound around the rear winding roll 100B is driven by 0B at the same speed as the feeding speed of the film 12, the lower cover film 12C side in the drawing bends outward. Since the cover film 12C is easily peeled off from the cutting line, the cover film 12C is easily peeled off by being adhered to the adhesive surface of the one-sided adhesive tape 96 running around the rear peel roller 92. Will be.

Accordingly, the cover film 12C is peeled off from the front end 12 of the trailing original film, and this is passed together with the single-sided adhesive tape 96 between the driving roll 110B and the rear pressing guide roll 116B and the rear winding roll 100B.
Will be wound up on the roll 103.

The film 12 from which the cover film 12C has been peeled off is wound into the lamination rolls 20, 20 through the film guide 124, and the substrate 1
It will be pressure-bonded to the film bonding surface 18A of No. 8.

When the rear peel roller 92 is driven to the contact position, a peel end counter (not shown) starts (S105), and after a certain time, the optical sensor 103B detects the presence or absence of the cover film 12C (S108). .

Next, the rear peel roller 92 is slightly lowered from the film path 13 by counting up the peel end counter (S106) (S107). When the cover film 12C is not detected by the optical sensor 103B (S108N), that is, when the peeling fails, the drive roll 110B and the rear winding roll 100B are immediately stopped (S109), and when detected, the operation is continued. (S110).

While the cover film 12C is being peeled off as described above, the front winding roll 100A, which has finished winding the cover film of the preceding original film, is pulled out to the outside by the front pull-out frame 114, and the support pipe 101 is drawn. The resin roll 103 is removed together with the wound cover film 12C and the one-sided adhesive tape 96, and a new resin roll 103 is set.

At this time, the front side single-sided adhesive tape feeding device 9
The tape coil 95 of the single-sided adhesive tape in 8A is also replaced with a new one, and the single-sided adhesive tape 96 unwound from this is wound around the front peel roller 90, and further from the outside of the intermediate roll 112A, the drive roll 110A and the front side. The tip is wound around the newly mounted resin roll 103 through a space between the pressure guide roll 116A, and then,
The front drawer frame 114A is pushed into the position below the film path 13 and set. In addition, single-sided adhesive tape 9
6 is newly mounted, the front side pressure guide roll 1
16A is driven in the clockwise direction in the figure by the swing lever 118 to open the gap with the drive roll 110A, the single-sided adhesive tape 96 is passed through here, and then the front side pressing guide roll 116A is returned to the position for pressing against the drive roll 110A. .

As described above, each time the original film is replaced, the front or rear drawer frames 114A, 11
4B is pulled out, and the single-sided adhesive tape and the resin roll 103 of the front or rear winding rolls 100A and 100B in the front or rear adhesive tape supply device are replaced.

The adhesive surface 56B of the one-sided adhesive tape 56 connecting the end 12D of the preceding original film and the leading end 12E of the following original film is pressed against the end 12D of the preceding original film by the second suction device 46. However, the present invention is not limited to this. For example, FIG.
As shown in FIG. 0, with the end 12D and the tip 12E of the film 12 adhered by the second adsorption device 46, these are adhered to the adsorption surfaces 24A, 24A of the first adsorption device 24.
A pressing member 65 such as a pressing roller that moves in the film width direction while pressing against B may be provided on the terminal cutter 62, so that the terminal 12D and the tip 12E are strongly bonded to the one-sided adhesive tape 56. In this case, the end cutter 62 is retracted.

Further, in the above apparatus, the film 12 is continuously attached to the substrate 18 which is intermittently conveyed with the cover film 12C peeled off in advance, but the present invention is not limited to this. Instead of cutting the film in advance and attaching it to the substrate with a temporary attachment member, a film attaching device that removes the cover film in advance and attaches it to the substrate while cutting according to the substrate length It is applied to the case where the raw film is continuously supplied, including the above.

Further, in the above apparatus, the end 12D of the leading original film and the leading end 12E of the trailing original film are cut and aligned, and they are connected by adhering with the single-sided adhesive tape 56 on the transparent support film 12A side. However, the present invention is not limited to this. For example, FIG.
As shown in FIG. 1, the translucent support films 12A are connected to each other by the single-sided adhesive tape 56 in a state where the leading end of the trailing original film is overlapped with the cover film 12C side of the trailing end of the preceding original film. It may be the one that has been done.

Further, in the above apparatus, three front peel rollers 90 and three rear peel rollers 92 are arranged in the film width direction, but the present invention is not limited to this, and two or four or more. The peel roller may be arranged in the width direction of the film, or one peel roller may be arranged at each of the front and rear sides over the entire width of the film.
In this case, as the single-sided adhesive tape wound around the peel roller, a plurality of single-sided adhesive tapes may be arranged at appropriate intervals in the longitudinal direction (film width direction) of the peel roller, and one single-sided adhesive tape covering the entire width of the film is used. You may do it.

Further, although the one-sided adhesive tape 96 is in the form of a roll, the length of the one-sided adhesive tape 96 is usually about the same as one original film, but the cover film 12C is sufficient. As long as it can withstand the pulling force, the length of the one-sided adhesive tape 96 is set as a length for adhering in a certain range from the connecting line of the preceding original film and the following original film, and the cover film is wound on the winding roll. After being wound to some extent, the cover film 12C may be peeled from the film 12 by pulling only the cover film 12C without using the single-sided adhesive tape.

In this case, the amount of consumption of the single-sided adhesive tape can be reduced. Further, the shape of the cover film wound by the winding roll can be stabilized.

Further, although the film 12 is formed by laminating the photosensitive resin layer 12B on the translucent support film 12A, the translucent support film 12A does not necessarily transmit light. For example, it may transmit electron beams, X-rays, ultraviolet rays, etc. and may be opaque.
