[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an edge peeling apparatus which acts on an end film surface of a substrate having a film adhered to at least one surface thereof to partially separate one end of the film from the substrate. Regarding the new structure. Specifically, it is an end peeling device capable of efficiently performing the above peeling operation.

2. Description of the Related Art In the manufacture of a printed wiring board, a wiring pattern is generally formed by forming a photosensitive etching resist layer on a conductive layer surface of a substrate having a conductive layer such as a copper foil formed on one or both sides of an insulating substrate. Thereafter, the pattern is exposed and developed to form a pattern corresponding to the wiring pattern, and etching is performed.

In the above operation, in order to protect the photosensitive etching resist layer before exposure, a protective film (hereinafter simply referred to as a film) is often adhered to the surface thereof. In the present invention, the term "film" does not have a strict meaning with respect to the thickness, but also includes a sheet having a function as a protective film.

[0004] Therefore, in the manufacturing process of the printed wiring board, it is necessary to peel off the film from the substrate before or after exposure.

Conventionally, as an apparatus for peeling a film adhered to one or both sides of a substrate, an end peeling apparatus for partially peeling off one end of the film on the substrate, and an edge peeling apparatus for peeling off the film on the substrate. There has been proposed a film peeling device comprising a peeling device for sequentially peeling and removing the film while simultaneously using means such as blowing air from an air knife or inserting a peeling jig between the film and the substrate.

[0006] The edge peeling device constituting the film peeling device is required to perform the edge of the film in close contact with the substrate reliably in a short time and without damaging the surface of the substrate. Various edge stripping devices have been proposed.

For example, a peeling unit constituted by mounting a plurality of pressing rollers in series on a support frame so as to have different axial angles, a pressing means for pressing the pressing roller against the film surface of the substrate, and a peeling unit are provided. An edge peeling device including a driving mechanism for relatively moving the substrate in the width direction of the substrate is exemplified.

The peeling of the edge of the film on the substrate by the edge peeling device is performed by pressing a pressure roller of a peeling unit on the film surface of the distal end of the substrate held by the holding roller so that the distal end protrudes. While pressing
This is performed by causing the substrate to reciprocate relatively in the width direction of the substrate to generate a strain stress between the pressing rollers having different axial angles, thereby peeling the film.

[0009]

However, according to the above-described edge peeling device, it is necessary to move the peeling unit a plurality of times in the width direction of the substrate in order to reliably peel the edge film of the substrate. However, there has been a problem that the processing time for one substrate is increased, and the productivity is reduced.

In order to reduce the number of movements of the peeling unit, it is conceivable to increase the number of pressing rollers or to increase the pressing force of the pressing rollers.

However, even if the number of the pressing rollers is increased, the peeling effect is little improved, and if the pressing force of the pressing rollers is increased, the substrate may be damaged.
It is not an effective means.

[0012] Therefore, there has been a demand for the development of an edge peeling device capable of performing the work of peeling the edge of the film adhered to the substrate in a short time without damaging the substrate.

[0013]

Means for Solving the Problems The present inventors have studied to solve the above problems. As a result, by providing an air knife between the pressure rollers mounted on the support frame so that the shaft angles are different, distortion is caused by the pressure rollers,
Air can be blown into the film with the gap,
As a result, it has been found that the end portion of the film attached to the substrate surface can be reliably peeled off, and the present invention has been completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. 1, 2 and 3, but the present invention is not limited to these embodiments.

FIG. 1 is a perspective view showing one embodiment of a typical edge peeling device of the present invention. FIGS. 2 and 3 are a front view and a plan view, respectively, showing one embodiment of a peeling unit used in the edge peeling device.

The edge peeling device according to the present invention includes an edge film surface 1 of a substrate 101 having a film adhered to at least one surface.
02, an end peeling device that partially separates one end of the film from the substrate, wherein at least one pair of at least two pressing rollers 2, 3, 4, 5 is provided on the support frame 1 at an axial angle. Are arranged in series so as to be different from each other.
And a drive mechanism 9 for relatively moving the peeling unit 7 in the width direction of the substrate 101. The peeling unit 7 includes a pressing means 8 for pressing the pressing roller against the film surface. Is done.

In the present invention, the peeling unit 7 is mounted on the support frame 1 in a state where at least two pressing rollers 2-3 and 4-5 are arranged in series with different axial angles.

The pressing rollers 2, 3, 4 and 5 are not particularly limited as long as their surfaces are made of a material having a sliding resistance to the film surface. Examples of the material include rubber, resin, and wood. Further, a metal having a plurality of grooves formed on the surface of a metal such as iron, stainless steel, and aluminum can also be used.

The size of the pressing roller is not particularly limited, but usually a diameter of 5 to 50 mm is preferable, and a width of 5 to 50 mm is appropriate.

In the present invention, the arrangement of the pressing rollers having different axial angles means that the angle of the central axis is set to an appropriate angle difference α so that the direction of the pressing rollers is relatively inclined as shown in FIG. It means to arrange. The angle difference may be set so as to be provided between the adjacent pressing rollers. In this case, one of the adjacent pressure contact rollers is
It may be provided so as to be horizontal to the running direction as shown by the pressure contact rollers 3 and 4. The angle difference α between the central axes of the pressing rollers is preferably such an angle that the film is twisted when the pressing rollers are moved by pressing the surface of the film with a predetermined pressure. Generally 1 to 1
It is preferable to have an angle difference θ of 0 degrees. Further, the arrangement of the pressing rollers in series means that they are arranged substantially linearly in the running direction due to the rotation of the pressing rollers.

The optimum interval between the pressing rollers arranged in series varies depending on the size, material, thickness of the film to be peeled, and the like, and cannot be unconditionally limited. The degree is preferred.

In the present invention, the number of the pressing rollers per support frame is sufficient to be two, but more than two pressing rollers may be provided.

In the present invention, the peeling unit 7 has a pressing means for pressing the pressing rollers 2, 3, 4, 5 against the film surface of the substrate. The installation mode of the pressing means is not particularly limited as long as it is provided to have such a function. For example, as shown in FIG. 1, it is preferable that a pressure mechanism 8 such as a pneumatic cylinder mechanism is mounted above the support frame 1 so that the support frame 1 can be moved up and down. In this case, the pressing varies depending on the strength, thickness, and the like of the film attached to the substrate, but it is generally preferable to adjust the pressing so that a load of 5 to 10 kg acts on the support frame.

The most significant feature of the present invention is that an air knife 6 is provided between the press rollers 2-3 and 4-5 having different axial angles. By providing such an air knife,
At the moment when the film is distorted due to the action of the pressing rollers having different axial angles and a gap is formed between the film and the substrate, air is blown into the portion to enhance the peeling action of the end portion.

The installation mode of the air knife 6 is not particularly limited as long as it can jet air to a position where the above function can be exerted between the pressure contact rollers having different axial angles. Generally, as shown in FIGS. 2 and 3, it is preferable to provide the pressing roller near the end of the support frame 1. The shape of the nozzle of the air knife is generally a round shape, but a slit shape, a square shape, and the like can also be adopted. Further, the air knife need not be provided between all the pressing rollers, but may be provided between at least one roller having a different axial angle. As a specific installation position, as shown in FIGS. 2 and 3, an air supply line may be built in or provided in a support frame between the pressing rollers, or an external supply line (not shown) may be provided. You may provide. In addition, as shown in the drawing, when a pressure-contact roller is provided on each side of the substrate to form a peeling unit, an air knife is attached to one of the support frames, and air is supplied to both sides of the substrate from the center of the substrate. By providing the nozzle so as to operate, the function of the present invention can be exhibited without providing air knives on the upper and lower support frames.
As the shape of the nozzle of the air knife, it is preferable to use a vertically long slit because air can be supplied between the substrate surface and the film without depending on the thickness of the substrate.

The air pressure of the air knife is not particularly limited, but is preferably about 1 to 5 kg / cm ² .

In the present invention, the width direction moving means is not particularly limited as long as it has a function of relatively moving the plurality of peeling units in the width direction of the substrate. For example, a mode in which the peeling unit is moved relative to the substrate, a mode in which the substrate is moved relative to the peeling unit,
Alternatively, there is a mode in which both the substrate and the peeling unit are moved. Among them, an embodiment in which the peeling unit is moved with respect to the substrate is recommended.

Referring to FIG. 1, such a typical embodiment will be described. The width direction moving means 9 is composed of a support rail 11, a cylinder mechanism 12, and a fixture 10 provided in parallel with the width direction of the substrate 101. The peeling unit 7 is attached to the support rail 11 by the fixture 10, and is movable along the support rail 11. Further, the peeling units 7 are connected to the cylinder mechanism 12, respectively, and are driven in the width direction of the substrate by the cylinder mechanism.

In the present invention, the peeling of the film is performed by moving the peeling unit 7 to one side in the width direction of the substrate, and pressing the pressing rollers 2, 3, 4, and 5 of the peeling unit by a pressing mechanism 8 as pressing means. After pressing, it is performed by moving to the other side by the width direction moving means.

In the present invention, other structures are not particularly limited, and the structure of a known edge peeling device is employed without any particular limitation.

For example, it is preferable that the holding of the substrate is performed by a holding table 104 which also serves as a transfer mechanism. That is, for example, after the substrate is transported by the transport means constituted by the transport roller, the transport roller is stopped so that the end 102 of the substrate 101 protrudes, and the substrate can be used as a holding table as it is.

In this case, it is preferable to provide a substrate stopper (not shown) in order to prevent the substrate from being moved by the pressing roller. Such a substrate stopper may be any as long as it has a function of holding down the substrate with respect to the holding table 104.
When a drive roller that can move up and down is provided above the substrate, the substrate can be held down by lowering the roller in a stopped state. Further, a mechanism for separately lowering and holding the substrate may be provided. Further, in order to stop the substrate at a predetermined position, it is preferable to provide a stop mechanism for preventing the moving roller from advancing the substrate. Further, when the substrate is processed by providing the peeling unit above and below the substrate, in order to smoothly advance the substrate between the pressing rollers located at the end of the peeling unit, the further end of the edge pressing roller is used. It is preferable to attach the guide roller 103 so that a gap (t) of 0.1 to 3 mm is slightly formed when the pressure contact rollers of the upper and lower peeling units abut against the portion.

The substrate from which the edge film has been peeled off is subsequently sent to a film peeling device by a known transport means, and the film is peeled off from the substrate.

[0034]

According to the edge peeling device of the present invention, the edge film of the substrate can be surely peeled only by passing the peeling unit 7 once from the edge to the edge of the substrate.

Accordingly, the working time can be drastically improved as compared with the conventional apparatus in which the end film is reliably peeled off only by reciprocating the peeling unit.

In contrast, in the conventional edge peeling device equipped with four pressure contact rollers, the peeling effect when the peeling unit is reciprocated is compared with the peeling device of the present invention.
The peeling effect when the peeling unit to which the same number of press rollers are attached is moved forward is equal to or more than that.
