Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for cutting a continuous film supplied by a roll into a specified length and temporarily welding the film to a predetermined position on a separately supplied substrate. .

[0002]

2. Description of the Related Art Conventionally, when a printed circuit board is manufactured, the surface of a conductor layer such as a copper foil laminated on a substrate such as an epoxy resin or a conductor layer laminated on a flexible substrate having a high flexibility such as a polyimide. Next, there is a step of laminating a film-like photoresist forming layer comprising a carrier film and a photosensitive layer (adhesive layer).

[0003] Before the photoresist forming layer is laminated on a substrate as a printed circuit board, the substrate is preliminarily processed by using a temporary fixing device provided with a thermocompression bonding, an adhesive, or a welding device. Fixed in several places above.

A conventional example of such a temporary fixing device (temporary welding device) and a laminator including the same is disclosed in
No. 146741, JP-A-2-196633,
JP-A-2-196656 and JP-A-5-15
A structure disclosed in Japanese Patent No. 4918 is known.

[0005] Since these laminators have a structure in which the film is directly sucked by a suction member or the like, especially when the film is thin, the film is evacuated from a hole formed in the suction member. By doing so, wrinkles occur and the problem that the film cannot be properly laminated, and furthermore, when the substrate on which the film is temporarily fastened is conveyed between a pair of laminating rolls, There was also a problem that the film was rubbed and damaged.

Some of these apparatuses have a structure in which a film is pulled and fed by moving a suction member or the like while holding the leading end of a continuous film by suction. Due to the rotation and the resistance when removing the polyethylene layer as a protective film,
Tension is generated in the film, adversely affecting the film,
Further, another device has a problem that its structure becomes complicated because it is necessary to provide a tension roll for controlling the slack of the film and an air cylinder for vertically moving the roll.

In addition, the conventional apparatus has a complicated structure for moving a suction member or the like holding a film by suction along a predetermined path so as to approach the conveyed substrate. And the control of the evacuation accompanying the movement of the suction member is complicated.

[0008]

SUMMARY OF THE INVENTION In view of such circumstances, an object of the present invention is to provide a method and apparatus for temporarily welding a material film to a substrate with a simple structure and reliably.

[0009]

According to a first aspect of the present invention, there is provided a temporary welding method, comprising the steps of: feeding a film unwound from a material roll to a peeling guide placed in front of a cutter; Through a protective film that is wound on a take-up roll, and a material film from which an adhesive layer is exposed, and then cuts the tip of the material film and rotates the take-up roll to rotate the protective film. The winding force of the film is applied to feed the material film forward toward the peripheral surface of the measuring roll, and the time when the leading end of the film is moved to the reference position of the measuring roll is detected, and the rotation drive of the winding roll is performed. The measuring roll is rotationally driven in conjunction with the above, and the material film is moved while being adsorbed on the peripheral surface of the measuring roll, and the measuring roll is rotated by a predetermined angle. The rotation of both rolls is stopped, the rear end of the material film is cut by the cutter, and the material film having a predetermined length determined by the rotation angle of the measuring roll is attached to the measuring roll. The base material transported by the transport unit to the bonding position of the measuring roll by the transport unit in parallel with the rotation of the measuring roll, and the material film with the adhesive layer exposed is moved to the bonding position. Setting and temporarily welding a material film to the base material by welding means.

According to a third aspect of the present invention, there is provided a temporary welding apparatus, wherein each of the roll shafts respectively supports a material roll and a take-up roll, and a film fed from the material roll is peeled by passing through a peeling guide. The protective film is taken up on a take-up roll, and a material supply means of a type for feeding out the material film with the adhesive layer exposed, and arranged near the peeling guide to cut the fed-out material film to a predetermined length. And a measuring roll for controlling the rotation of the material film along the peripheral surface of the measuring roll while moving and measuring the material film and feeding the material film to the welding position. Control to output a position detection signal based on the fact that the cut material film has moved to a position advanced by a predetermined rotation angle from the reference position of the measuring roll. Step, welding means for temporarily welding the material film and the base material at the welding position, and transporting the base material to the welding position in accordance with the feeding of the material film cut to a predetermined length, further, After welding the base material and the material film, it is provided with a conveying means for discharging, the tip of the peeling guide, the upper surface of the film on the material roll side, the supply direction of the material film from the peeling point of the protective film and Is disposed between the surface of the protective film that is pulled out in the opposite direction and wound on a take-up roll, and the feeding of the peeled material film is performed by winding tension of the winding operation of the protective film. And

With this configuration, the protective film is pulled in the direction opposite to the feeding direction of the material film along the peeling guide, so that the material film after the protective film has been peeled is driven by the rotation of the take-up roll. Of the protective film, and the protective film is fed almost straight forward toward the peripheral surface of the measuring roll. Then, when the film leading edge reaches the reference position of the measuring roll, the control unit outputs a position detection signal, and the measuring roll is rotationally driven by the driving unit, so that the material film is attracted to the measuring roll. It moves along its circumference. When the measuring roll rotates by a predetermined angle, the rotation of the measuring roll and the take-up roll is stopped by another position detection signal from the control means, and the cutter is operated to cut the material film of a predetermined length. Thereafter, the film is moved to the bonding position of the measuring roll, and on the other hand, the material film is temporarily welded to the base material carried into the bonding position by the transport means by the welding means.

[0012] Therefore, the film is cut and pasted as much as necessary, so that the material loss is small. Also, since the moving means of the material film is based on the action of the winding tension of the protective film, it should be driven by the driving means of the winding roll. The structure of the apparatus is simple, and the bonding of the base material and the material film is performed only by controlling the rotation angle of the measuring roll and the means for transferring the base material, and does not require a complicated control mechanism.

[0013]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view schematically showing a temporary welding apparatus 1 according to the present invention. The temporary welding device 1 is a device that cuts a continuous film 3 fed from a material roll 2 into a designated length and temporarily welds a predetermined position of a separately supplied base material 4. In the apparatus shown in FIG. 1, the same basic structure is provided above and below the conveying means 18 and 20 so that the film 3 to be bonded to the substrate 4 can be temporarily welded on one side or both sides of the substrate 4 simultaneously.

The film used here is usually a three-layer film composed of a protective film, an adhesive layer and a carrier film, and the adhesive layer forms a photoresist forming layer. To bond the film-like photoresist formation layer on a substrate such as a substrate, separate the protective film from the film, expose the photoresist formation layer on the remaining carrier film, and temporarily weld the material film and the substrate. It is temporarily fixed by a device, has adhesiveness by being heated by a laminator such as a vacuum press device, and is pressed and laminated on a base material.

The basic structure of the temporary welding apparatus 1 is shown in FIG. 2, and includes a material roll shaft 5 for supporting a material roll 2 for feeding out a film 3 and a winding roll 7 for winding a protective film 6 of material. A material supply means including a take-up roll shaft 8 for supporting, and a peeling guide 10 for peeling off the protective film 6 from the film 3;
The cutter 12 for cutting the carrier film 11 (also referred to as a material film) from which the adhesive layer 9 (see FIG. 4) has been exposed by exfoliation, a measuring roll 14 for measuring and sending the carrier film 11 to a welding position, Welding means 16 incorporated in the measuring roll 14 for temporarily welding the material film to the base material 4, a carry-in conveyor 18 for feeding the base material 4 to a welding position, and unloading for discharging the base material 4 to which the film 3 is temporarily welded. Transport means including the conveyor 20.

The material supply means includes a material roll shaft 5 and a take-up roll shaft 8, and passes the protective film 6, which has been peeled off from the material roll 2 through the peeling guide 10, to the take-up roll 7. It is configured in a winding format. In the present embodiment, various types of means for rotationally driving the take-up roll 7 can be used. Here, a drive motor for the drive roller 27 of the pair of guide rollers 27 and 28 and a drive motor for the take-up roll are used. Adjustment motor 41
(See FIG. 1), the protective film 6 passes through the peeling guide 10 and is
It is wound in a character shape and wound up on a winding roll.

The adjusting motor 41 is a motor having a smaller torque than a motor (not shown) of the driving roller 27, and holds the protective film 6 between the driving roller 27 and the take-up roll 7 in a tension state. According to this driving method, even when the winding diameter of the protective film 6 wound on the winding roll 7 changes, an equal tension is applied to the protective film 6, and the driving film 27 is moved between the driving roller 27 and the winding roll 7. The resulting sagging of the film can be eliminated and the carrier film 11 with the adhesive layer exposed is directed to the peripheral surface of the measuring roll by the action of the tension of the peeled protective film 6 by simply rotating the winding roll 7. Can be sent forward.

In FIG. 1, the present apparatus includes a motor 42 for a conveyor and a motor 43 for an unloading conveyor, which are driving sources of the conveying means, a motor 44 for measuring rolls,
A motor 45 for adjusting the film width is provided, and a suction hole 3 provided in a measuring roll 14 and a support 30 which will be described later.
A vacuum pump or a vacuum device 46 for adsorbing the carrier film 11 is disposed by the components 4 and 38.

In the temporary welding apparatus 1 of the present invention, FIG.
As shown in FIG. 3, a support block 22 for the peeling guide 10, a cutter unit 24 for cutting the carrier film 11, and a cutter unit 24 at positions close to the measuring roll 14.
A sensor means 25 provided in front of the measuring roll 14 so as to face the peripheral surface 14a of the measuring roll 14;
Two guide rollers 26 to 28 are arranged. In order to form a film of a predetermined length, the cutter 12 of the cutter section once cuts the carrier film 11 immediately after peeling in order to align the leading end of the film at the start of the work, and then sends the film to the reference position of the measuring roll 14. Carrier film 1
1 cuts the rear end of the film when the drive roller 27 and the measuring roll 14 stop rotating at a position advanced by a predetermined rotation angle of the measuring roll 14 based on a position detection signal from a control unit described later.

When the carrier film 11 moving along the rotation direction of the measuring roll 14 reaches the reference position Q of the measuring roll 14, the sensor means 25 detects this and outputs a position detection signal. The measuring roll driving motor (motor means) 44 is usually a pulse motor, rotates the measuring roll 14 at a predetermined angle, and moves the material film to a position advanced by a predetermined rotation angle of the measuring roll. And outputs a position detection signal based on this. Further, this motor means may be a combination of an encoder and a servo motor when film feeding accuracy is required.

Such a sensor means and a motor means are provided as constituent elements of the control means of the apparatus, and a position detection signal based on the fact that the material film has moved to a position advanced by a predetermined rotation angle from the reference position of the measuring roll. Is output to synchronize the operation of the cutter 12 with the stop of the rotation of the driving roller 27 and the measuring roll 14. These position detection signals are
It acts as a timing signal for interlocking rotation and stop of the drive roller 27 and the measuring roll 14.

As shown in FIG. 1, a pair of support blocks 22 are attached above and below both ends of the upper and lower measuring rolls 14, respectively.
And holding both sides of the elongated peeling guide 10 extending in the width direction of the film 3 and the support 30 which faces the film and forms the passage of the film 3. Also, the cutter unit 24 can slide left and right along a horizontal axis 32 (see FIG. 5) extending between the pair of support blocks 22, one by one with respect to the measuring roll 14.
It is arranged on the front end side of the support block 22. Cutter 1
Reference numeral 2 may be a rotating roller blade, but here, a push cutting blade is employed because of its structure.

A gap through which the film 3 passes is formed between the peeling guide 10 attached to the support block 22 and the support 30, and the support 30 has a plurality of suction holes 34 for holding the film 3 at the time of cutting. When the cutter 12 is cut while moving in the width direction of the film, the film 3 is held so as not to shift. Further, the tip of the support 30 extends forward from the peeling guide 10 and serves as a push-stand for the cutter 12.

As shown in FIG. 4, the support 30 serving as the push-off table may be a plate-like elastic body, and may be any material having a hardness necessary for the cutter 12 to push off the film. In addition, a slight gap may be provided between the measuring roll 14 and the support 30 to provide a structure in which the bottom surface of the support 30 contacts the measuring roll 14 at the time of cutting to back up the cutting load.

The peeling guide 10 has a wedge-shaped tip,
Has a sharp edge angle α. This cutting edge angle is important. The sharper the angle at which the film is peeled, the straighter the film that has been peeled. Conversely, if the angle is made obtuse, it will be attracted to the protective film 6 and lifted upward, and cannot be fed straight in the direction of the measuring roll. Therefore, by making the edge of the peeling guide an acute angle, the protective film 6 extends from the peeling point P along the tip inclined surface 10a of the peeling guide 10 and proceeds in a direction opposite to the feeding direction of the film 3 to form a pair of films. It is wound around the guide rollers 26 and 27 and wound on the winding roll 7.

In this embodiment, as shown in FIG. 1, the measuring rolls 14 are provided at upper and lower positions symmetrical with respect to the conveying means, and a motor 44 for rotating each measuring roll 14 is provided at a side portion (see FIG. 1) of the apparatus. 5). Measuring roll 1
A number of suction holes 38 are arranged on the peripheral surface of No. 4,
The diameter of the suction hole 38 is about 1 mm in order to avoid leaving a mark due to the film being sucked into the suction hole 38. This suction hole 38 is connected to a vacuum pump 46 like the suction hole 34 of the support 30. Therefore, the carrier film 11 moves along the peripheral surface 14a while adsorbing to the measuring roll 14. In addition, since the total number of the suction holes 38 is different due to the difference in the cut length of the film, for example,
It is also possible to divide the inside of the measuring roll 14 into three parts and switch both sides so that the suction range can be selected by a valve.

As shown in FIG. 5 and FIG.
6 are provided at two locations in the width direction of the film so as to be capable of performing point welding. Each of the welding means 16 is connected to a pneumatic cylinder 17 or the like and is capable of moving up and down in the A direction. It is mounted on 14 mounting blocks that are movable in the axial direction. Therefore, the welding means 16
Can be moved right and left along the horizontal axis 40, and can be positioned at a desired welding position to adjust the width pitch. The welding means 16 may be the same as a commercially available soldering iron with a temperature setting device. However, in order to protect the film at the time of welding, it is desirable that the shape of the heat-generating tip portion that comes into contact with the film is spherical, and the surrounding surface is covered with a heat-resistant elastic material such as silicone rubber.

In FIG. 5, a stopper 46 disposed outside the tip of the welding means is provided upright on a moving block 48 for adjusting the width of the film.
The motor 45 shown in FIG. 4 can be moved and adjusted to the left and right according to the width of the film. The pressing force of the tip during welding can be adjusted by air pressure control. In the example of the present apparatus, 23
The welding means can be adjusted to a width of 0 to 500 mm.
The distance from the film tip to the welding point can be adjusted in the range of 0 to 20 mm by the dimension B of the long hole 14b of the measuring roll 14.

As the transport means, a drive motor roller conveyor or a belt conveyor structure is used, respectively. The entrance conveyor 18 on the entrance side needs to adjust the dimensions of the film width end face on the measuring roll 14 and the base end face. It has a function of correcting the position of the base material so that the material end face is parallel to the film end face. When a belt is used for conveyance, a structure that can clean the surface of the belt and prevent generation of dust on the surface is required.

On the other hand, a cleaning mechanism can also be provided on the discharge conveyor 20 on the outlet side. The carrier film 11 temporarily welded on the conveying means has a non-sticky property and a property of sticking at the body temperature. Therefore, the conveying means does not contact the entire surface and the lower part of the conveying surface is not generated. It is desirable that a heat source be provided as much as possible to prevent hot air from other sources.

A method for temporarily welding a material film to the substrate 4 using the temporary welding apparatus 1 having the above configuration will be described below.

First, the following first step is performed as a preparation stage for starting the work.
Perform the process. The operator passes the film 3 unwound from the material roll 2 through the guide roller 28 and the passage between the peeling guide 10 and the support 30. Then, the protective film 6 is peeled off at the start end of the film 3 that has exited this passage, pulled out on the peeling guide 10, and wound around the pair of guide rollers 26 and 27 in an S-shape to wind up the protective film 6. Wrap around roll 7.

Next, the second step is performed as follows. Since the wound protective film 6 is wound by the driving means of the winding roll 7, that is, the driving roller 27 and the adjusting motor 41 for the winding roll, the film 3 is applied by the tension acting on the protective film 6 at the peeling point P. The carrier film 11 (material film) from which the adhesive layer 9 is exposed is sent forward toward the peripheral surface of the measuring roll while the protective film 6 is peeled from the substrate. Immediately after the carrier film 11 has passed the peeling point P, the rotation of the take-up roll 7 is temporarily stopped, the cutter 12 is lowered, and the carrier film 11 is cut.

Then, the take-up tension acts on the protective film 6 by driving the motor of the drive roller 27 and the forcible motor 41 to rotate the take-up roll 7, whereby the protective film 6 and the carrier film 11 are sequentially separated. The carrier film 11 is sent out, and the film tip 1
1a reaches the reference position Q of the measuring roll 14.

In the next third step, the reference position Q
Then, the sensor means 25 detects the leading end of the film and outputs a position detection signal. Based on this timing signal, the driving of the measuring roll 14 is started in synchronization with the rotation of the driving roll 27. At the same time, by operating the vacuum pump, the carrier film 11 is moved to the peripheral surface 14a of the measuring roll.
While moving along the measuring roll 14.

Then, in the fourth step, the measuring roll 1
4 is rotated by a predetermined angle, this time, the reference position Q
At a position advanced by a predetermined rotation angle from, a position detection signal is generated based on the setting output of the predetermined angle position of the measuring roll 14 obtained by counting the step pulse from the motor means 44, and the control means The rotation of the take-up roll 7 is stopped, and the cutter 12 is stopped.
Drops and cuts the film.

In the fifth step, when the cutting of the carrier film 11 is completed, the film has a predetermined length determined by the setting of the rotation angle of the measuring roll 14 and is attracted to the peripheral surface 14a of the measuring roll. , Measuring roll 14
With the rotation of, it moves to the bonding position of the measuring roll 14 and stops.

On the other hand, the base material 4 is
Within the time of one cutting and moving step, they are aligned in the width direction on the carry-in conveyor 18, conveyed to a predetermined position under the measuring roll, and stopped. Then, in the sixth step, both the base material 4 and the carrier film 11 are set at predetermined positions, and the welding means 16 is lowered, so that the carrier film 11 and the base material 4 are spot-welded at predetermined positions. .

As a further step, after the welding, the base material 4 and the carrier film 11 are moved in the traveling direction on the conveyor 2.
After the discharging operation, the measuring roll 14 is rotated or reversed to return to the original reference position Q. Further, the take-up roll 7 is driven to rotate by the drive roller 27, and the film cut end separated from the rear end of the carrier film 11 is moved to the reference position Q.
The carrier film 11 is temporarily welded to the base material 4 continuously by repeating the process, that is, rotating the measuring roll by a predetermined angle, cutting the film, moving to the bonding position, and temporarily welding operation sequentially.

The base material and the like temporarily passed through the temporary welding device are sequentially supplied to the next laminator to complete a laminated product such as a printed wiring board.

The carrier film 11 with the adhesive layer exposed is sent out toward the peripheral surface 14a of the measuring roll by the action of the winding tension of the winding roll 7, and the leading end 11a of the carrier film is moved to the reference position Q of the measuring roll 14. The carrier film 11 is temporarily welded to the base material 4 by moving and controlling the cutting of the carrier film 11 by the cutter 12 and the rotation drive of the winding roll 7 and the measuring roll 14 based on the output signal from the sensor 25. A series of operations can be performed continuously.

[0042]

As is apparent from the above description,
According to the present invention, since a continuous film is sequentially cut to a predetermined length without being wasted and temporarily welded to the base material, the film is stuck to the base material as needed, so that material loss is reduced. In addition, the movement of the film can be performed only by the drive means of the winding roll by the action of the winding tension of the protective film, so that the structure of the apparatus is simplified, and the bonding of the base material and the film is performed by rotating the measuring roll. Only the angle and the means of transporting the substrate need be controlled, and no complicated control mechanism is required.
