Description

  The present invention relates to a method and an apparatus for forming a three-dimensional circuit board, and more particularly, to an apparatus and a method for forming a three-dimensional circuit board by sticking a circuit board to the surface of a roller.

  As electronic devices such as mobile phones become smaller, more multifunctional, and lower in cost, it is required that the circuit board be compactly attached to the inner and outer surfaces of the housing. Instead, a three-dimensional thing may be required. Also in the field of copying machines, it has been proposed to form a three-dimensional circuit board by adhering a circuit board to a part of the surface of a roller such as a developing roller or over the entire circumference.

  As a method of forming a circuit board on the entire surface of such a roller, a circuit board is formed by patterning a conductor layer using a circuit board provided with a conductor layer such as copper on the surface of an insulating film such as polyimide. A method of forming and sticking the obtained circuit board around the entire surface of the roller is conceivable. Since such a circuit board can be manufactured in a large amount and at a low cost, it can be advantageous if it can be attached to a roller.

  By the way, Patent Document 1 describes a method of sticking a film to a cylindrical or cylindrical can body by a rotary cutter method. In this method, a flexible film that cannot be held on its own is cut to a desired length with high accuracy, and the film obtained by cutting is supplied to the can body, and then laminated to a film can body. Can be attached. More specifically, a flexible film that cannot be held on its own in a wound state is wound on a feed roll and a cutting roll by vacuum suction, and the peripheral speed of the feed roll is made slower than the peripheral speed of the cutting roll, and tension is applied to the film. By dividing the vacuum suction part of the cutting roll into multiple parts and adjusting the vacuum strength, the film is made slippery, a certain interval is created in the cut film, and the timing of lamination to the can body is obtained. The laminate part of the laminating roll turns and pressurizes to eliminate the dent of the film, and air is not left between the can body and the film, so that the can body is satisfactorily laminated.

  The sticking method by the rotary cutter system described in Patent Document 1 was developed for the purpose of sticking a label on the surface of a bottle of a beverage container such as a can or a bottle. For this reason, it is not necessary to strictly manage the positional accuracy and the like for attaching the label, and when the label is attached to the entire surface of the beverage container, there is no problem even if an overlap or a gap occurs in the film.

  On the other hand, when sticking a film circuit board for electronic equipment all around the surface of the roller, if there is an overlap or a large gap on the film circuit board, a short circuit or poor conduction occurs in the wiring that constitutes the circuit, This affects the electrical characteristics of the circuit, which is a big problem. However, even if the film circuit board is cut with high precision so that there is no overlap or large gap at the time of sticking in response to such a request, there is variation, and there is also variation in the finished diameter of the roller itself. At present, sufficient measures have not been taken to deal with such problems.

As for the gap, when a resin is applied for protecting the surface of the film circuit board, the step of the gap may not be filled and the end of the film circuit board may be exposed.
Japanese Patent Laid-Open No. 10-236446

  The present invention relates to a method and apparatus for forming a three-dimensional circuit board having a mechanism capable of suppressing a gap when a circuit board is attached to the surface of a cylindrical or cylindrical object such as a roller, particularly over the entire circumference. The purpose is to provide.

  In the method for forming a three-dimensional circuit board according to the present invention, an object having a columnar shape or a cylindrical shape is rotatably held in a state where the central axis is horizontal, and the adhesive film with a separator is adsorbed to the moving means.

Then, the circuit board is transported in a direction having a set angle θ that is not 90 °, and an end of the circuit board is joined to the surface of the adhesive film adhered to the surface of the object, While attaching the circuit board to the surface of the adhesive film by rotating the object and the adhesive film while controlling the pressure to be pressed against the surface, the object is The theoretical angle Θ is obtained by the following equation: cos Θ = L1 / (L0−Δ) from the circumferential length L0 by the surface of the adhesive film adhered to the substrate, the length L1 of the circuit board, and the set gap Δ, and the set angle θ Is determined by approximating the theoretical angle Θ.

  When the adhesive of the adhesive film with a separator is an adhesive having tackiness at room temperature, and the separator is also provided on the back surface of the film, the adhesive film with the separator is placed on the surface of the object. Before joining, the separator on the back surface is removed.

  On the other hand, when the adhesive of the separator-attached adhesive film is a heat-curable adhesive, before bonding the separator-attached adhesive film to the surface of the object, the film is heated, or After heating the object, the film is bonded to the surface of the object.

  In addition, a separator can also be abbreviate | omitted when using a thermosetting type as an adhesive agent. In this case as well, by heating the thermosetting adhesive film or the object, the adhesive is activated at the time of joining to impart tackiness, and the thermosetting adhesive film is first applied to the object. To wear. Thereafter, while maintaining the activation of the adhesive, the circuit board is adhered to the surface of the adhesive film to form a three-dimensional circuit board.

  Also, instead of the adhesive film, the surface of the object that is columnar or cylindrical in advance is coated with a thermosetting adhesive, and the object is rotatably held with the center axis being horizontal, After heating the object, the circuit board is attracted to the moving means, the moving means is moved, the end of the circuit board is joined to the surface of the object, and the surface of the object is You may make it stick the said circuit board on the surface of the said target object by rotating horizontally while controlling the pressure to press, and rotating the said target object.

It may consist of two rotating rollers arranged so that the object is placed between them and rotates.

  In the present invention, when forming a film circuit board over the entire circumference on the surface of a cylindrical or cylindrical object such as a roller, the adhesive film is first attached to the surface of the object, or the object After the adhesive layer is formed on the surface of the film, the circuit board without the adhesive layer is separately attached to the adhesive film or the adhesive layer, so that the film circuit board is attached to the object. Yes. In addition, by making the direction of the entire rotation mechanism changeable, it is possible to effectively suppress the gap that occurs when the film circuit board is attached over the entire circumference with respect to the length of the film circuit board and the diameter of the object. it can.

  An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing an embodiment of a three-dimensional circuit board forming apparatus according to the present invention. FIG. 2 is a schematic view showing the reference setting mechanism shown in FIG.

  The apparatus for forming a three-dimensional circuit board according to the present invention holds an object (1) having a columnar shape or a cylindrical shape in a state where the central axis is horizontal, rotates the central axis as a rotational axis, A rotation mechanism (10) that can change the direction of the axis within a range of 0 to 10 °, and a holding mechanism (20) that holds the adhesive-attached adhesive film or circuit board (2) and transports it horizontally. The relative positional relationship can be adjusted so that the adhesive film with a separator conveyed on the surface of the rotating object (1) or the adhesive layer of the circuit board (2) is in contact, and the object ( And a control mechanism (30) capable of controlling the pressure to be pressed against the surface of 1) uniformly.

  The separator-attached adhesive film or the circuit board (2) is housed in the reference dispensing mechanism (40). In addition, an adhesive film with a separator and a circuit board (2) are cut | disconnected previously to a predetermined size according to the magnitude | size of the target object stuck. For example, when the circuit board is formed on the entire surface of the roller that is the object (1), the length of the side of the circuit board (2) in the direction of the rotation axis of the object (1) is the rotation of the object (1). The length is the same as the length in the axial direction, and the length of the side corresponding to the circumferential direction of the object (1) is set to a size obtained by subtracting a set gap from the circumference of the object (1). The set gap is determined in consideration of an error in cutting accuracy and a tolerance in the shape of the object.

  A reference | standard taking-out mechanism (40) functions as a holder of the adhesive film with a separator cut | disconnected by the predetermined size, and a circuit board (2). The reference out mechanism (40) includes, for example, a resin fixed plate (41) and a movable plate (42). The adhesive film with separator and / or the circuit board (2) cut to a predetermined size is set in the reference delivery mechanism (40) with the circuit surface facing up in the case of the circuit board. Positioning by the reference out mechanism (40) is performed by the movable plate (42) pressing the adhesive film with a separator and the circuit board (2) onto the fixed plate (41) which is a fixed reference plate in the XY directions. Set it to the correct position.

  In addition, when using the adhesive agent which expresses adhesiveness at normal temperature, generally the separator is distribute | arranged to the adhesive film with a separator on the both surfaces of the film by which the adhesive agent was apply | coated on both surfaces. In this case, both the adhesive film with a separator and the circuit board can be alternately arranged with respect to one reference delivery mechanism (40). However, even in this case, these may be arranged in different reference setting mechanisms (40).

  On the other hand, an adhesive film with a separator provided with a separator on one side can also be used. In this case, the separator-attached adhesive film and the circuit board are arranged in different reference dispensing mechanisms (40).

  Furthermore, when using a thermosetting adhesive that develops tackiness by heating, the separator can be omitted, and when a separator is provided, it can be attached to the surface side. ) May be used with the circuit board, or a different reference mechanism (40) may be used.

  When a plurality of cut adhesive films with a separator and a circuit board (2) are set together, a magazine that can be stored by stacking a plurality of sheets is attached to the reference delivery mechanism (40).

  The separator-attached adhesive film and the circuit board (2) set at an accurate position are adsorbed by vacuum suction to the holding mechanism (20) having a small hole and conveyed. Specifically, the holding mechanism (20) includes a suction plate made of a resin plate or a mechanism metal plate having a small hole that enables vacuum suction, a vacuum suction system communicating with the hole, and the suction plate and the vacuum suction system. It is composed of a mechanism for moving up and down and moving in the horizontal direction.

  The holding mechanism (20) moves up after adsorbing the adhesive film with a separator or the circuit board (2).

  When the adhesive layer of the adhesive film is made of an adhesive that is heated to develop tackiness, the device includes a heating mechanism (50). As the heating mechanism (50), a known heater can be employed. Since the active conditions vary depending on the type of adhesive, heating is performed by optimizing the heating temperature and heating time of the heater according to the adhesive used. The heating temperature is within the activation temperature range of each adhesive.

  In addition to the heating mechanism (50) for heating the adhesive layer of the circuit board (2), the heating mechanism (50) for heating the object (1) to heat the adhesive layer at the time of bonding can also be employed.

  Moreover, the drawing shows an aspect in the case of using a thermosetting adhesive as the adhesive layer of the adhesive film (2). On the other hand, when the adhesive layer is made of an adhesive having adhesiveness at room temperature, and the separator is also attached to the back surface of the adhesive film (2), a removal mechanism for removing the back surface separator is provided. Be prepared. Also for the removal mechanism, a known apparatus for peeling and removing the separator can be used.

  You may provide these heating mechanisms (50) and removal mechanisms simultaneously.

  Then, the holding mechanism (20) is moved, and the adhesive film with a separator or the circuit board (2) is placed above the rotating mechanism (10) on which the object (1) made of a metal or resin roller is set. Move. If necessary, at this position, the holding mechanism (20) is lowered, and the adhesive film or the circuit board (2) is first pressed against the surface of the object (1). The end of the circuit board (2) (the end on the side in the rotational axis direction and the front in the traveling direction) is joined to the surface. However, this joining may be achieved only by horizontal movement. The rotation mechanism (10) is fixed by an angle fixing bolt (11), and is set to 0 ° for normal use. For example, a set angle θ of 0 ° to 10 ° is set according to the length of the circuit board (2) that differs for each lot. can do.

  For convenience of explanation, the adhesive film with a separator and the attachment of the circuit board (2) to the object (1) are described at the same time. Actually, however, first, the adhesive film with a separator is the object (1 Next, the separator attached to the surface of the adhesive film is removed, and at the same time, the circuit board is attached to the surface of the adhesive film, so that the object (1) A three-dimensional circuit board having a film circuit board formed thereon is obtained.

  The rotation mechanism (10) has a structure in which two freely rotatable rollers are adjacent to each other. A metal roller can be adopted as the rotating roller. If necessary, an elastic material such as rubber attached to the entire circumference can be used. Both ends of the roller are rotatably supported by a bearing or the like so that the rotation of the object can be followed. The object (1) is placed on the space between the two rotating rollers so that the side of the adhesive film with separator and the circuit board (2) is parallel to the rotation axis of the object (1). The holding mechanism (20) moves. In addition, for example, when it is not necessary to form an adhesive film with a separator or a circuit board (2) on both ends of the object (1), the both ends are supported by bearings and supported rotatably. May be.

  Thereafter, the holding mechanism (20) adsorbing the separator-attached adhesive film or circuit board (2) moves horizontally, and at the same time from the side of the separator-attached adhesive film or circuit board (2), the object (1). In the case of an adhesive film with a separator, in the case of a circuit board, in the case of an adhesive film with a separator, in the case of a circuit board, it was previously attached to the object (1), and the separator was removed. The adhesive film is adhered to the entire surface. Therefore, air is not involved between the adhesive film and the object (1) and between the adhesive film and the circuit board. Further, even if the shape of the object (1) such as the length or diameter changes, the holding mechanism (20) can be attached without changing the jig or structure. Moreover, it is performed by a mechanism using air or hydraulic pressure so that the pressure at the time of bonding is constant.

  In the present invention, when the film circuit board is formed on the entire circumference of the object (1), the angle fixing bolt (11) is loosened, and a desired set angle θ is attached to the direction of the rotation mechanism (10). The gap bonded to the object (1) can be suppressed. The same applies to the case where the adhesive layer and the film circuit board are separately bonded to the object (1).

  When bonding separately, the edge of the adhesive layer and the edge of the film circuit board are misaligned, and the set angle θ is mainly set for the gap formed between the edges of the film circuit board It is desirable to do. In addition, as described above, after the adhesive film with a separator is attached in advance to the surface of the object, the circuit board is attached to the object using the adhesiveness of the adhesive film, The surface of the object is covered with a heat-curable adhesive, a heat-curable adhesive layer is formed on the surface of the object, and the object is directly heated to give the adhesive layer tackiness. In this state, a circuit board on which no adhesive layer is formed may be similarly attached to the surface of the object. Even in the case of using a thermosetting adhesive film, it is preferable to use an adhesive film with a separator, considering the ease of alignment at the time of sticking, the elongation of the film, etc., but the separator is omitted and the adhesive is used. These may be stuck by activating the adhesive by heating when sticking the film and when sticking the circuit board.

  First, a circuit board was produced as follows.

Using a 35 μm thick PET film (A4100, manufactured by Toyobo Co., Ltd.), a copper thin film was formed on the surface by sputtering, and then a copper layer was formed by an electrolytic copper plating method. For the electrolytic copper plating, a copper bath having a thickness of 8 μm was formed by using a plating bath having a copper sulfate concentration of 90 g / liter and a sulfuric acid concentration of 180 g / liter at room temperature and a cathode current density of 2 A / dm ² .

  Furthermore, after applying a dry film resist (AQ-1158, manufactured by Asahi Kasei Co., Ltd.) on the surface of the copper layer by a photoresist method, and producing a wiring-shaped mask, exposure is performed on the dry film resist, development, etching, And dry film peeling was performed and the circuit board was obtained.

  The obtained circuit board and an adhesive film with a separator having a tackiness at room temperature (Dainippon Ink Chemical Co., Ltd., double-sided adhesive tape # 8616), each side of the rotating shaft in the direction of 49 It was cut so that there were five types from .68 mm to 50.48 mm, and the side in the vertical direction was 350 mm. After cutting, the film was set in the cassette (40) shown in FIG. 2 so that the adhesive film with a separator and the circuit board were alternately arranged.

  Next, the sticking process was performed using the formation apparatus of the three-dimensional circuit board which showed the schematic in FIG. The apparatus includes a vacuum suction (vacuum) lift (30, a lifting mechanism using an air cylinder), a suction plate (20) connected to the lift, a heater (50), a protective film (back separator) removal device (circuit board The separator attached to the back surface has a leader tape attached to the end of the separator, and a mechanism for peeling the separator by grasping and peeling the leader tape), rotating device (10), and heater for the rotating device (Not shown). Further, another protective film (surface separator) removing device (same mechanism as the removing device for the back separator) is also provided adjacent to the rotating device.

  The vacuum lift (30) can move the suction plate (20) up and down and move horizontally from the cassette (40) to the rotating device (10). The protective film removing device is installed on the line from the cassette (40) to the rotating device (10) adjacent to the heater (50). The heater (50) was not used.

  As the rotating roller of the rotating device (10), rollers each having a diameter of 40 mm and a length of 400 mm, each having a silicon rubber attached to the surface of a metal roller, were used.

  As a work, first, for a roller made of an aluminum pipe having a diameter of 16 mm and a length of 300 mm, the circumferential length L0 by the surface of the adhesive film stuck to the roller, the set gap Δ, and the length of the circuit board The theoretical angle Θ is obtained from the calculation formula cos Θ = L1 / (L0−Δ) based on the length L1, and the angle of the rotating device (10) is set so as to be inclined with respect to the transport direction at a set angle θ that approximates the theoretical angle Θ. The fixing bolt (11) was adjusted. Each value is shown in Table 1. Thereafter, the roller (1) was placed between the rollers of the rotating device (10).

  First, the adsorption | suction board (20) was dropped on the adhesive film with a separator accommodated in the cassette (40), and the adhesive film with a separator was adsorbed. The suction plate (20) was raised and moved horizontally. During the horizontal movement, the separator covering the back surface of the adhesive film with a separator was peeled and removed by a protective film (back separator) removing device. When the advancing direction end of the suction plate (20) reached the roller (1) on the rotating device, the suction plate (20) was lowered until the roller (1) was pressed by a preset pressure. After the end of the adhesive film in the advancing direction contacts the surface of the roller (1), when the suction plate (20) is moved horizontally, the roller (1) also rotates along with it, and the adhesive film adheres over the entire circumference. It was done. Then, the separator which coat | covers the surface of the adhesive film stuck on the surface of the roller (1) was peeled and removed with the protective film (surface separator) removal apparatus.

  Next, the suction plate (20) was lowered onto the circuit board (2) accommodated in the cassette (40) to suck the circuit board (2). The suction plate (20) was raised and moved horizontally. When the advancing direction end of the suction plate (20) reached the roller (1) on the rotating device, the suction plate (20) was lowered until the roller (1) was pressed by a preset pressure. When the suction plate (20) is moved horizontally after the advancing direction end of the circuit board (2) contacts the surface of the adhesive film, the roller (1) also rotates along with it, and the circuit board (2) is rotated over the entire circumference. Was pasted.

  Thereafter, the roller (1) to which the circuit board (2) was adhered was discharged, and a new roller (1) was placed on the rotating device (10). FIG. 3 is a perspective view of the resulting three-dimensional circuit board.

  From the obtained three-dimensional circuit board, the measurement gap δ between the side edges of the circuit board after pasting was measured for each. The results are shown in Table 1.

  It can be seen that the measurement gap after sticking can be controlled in a narrow range such as 0.07 to 0.13 mm with respect to the set gap of 0.10 mm.

It is the schematic which shows one Example of the formation apparatus of the three-dimensional circuit board of this invention. It is the schematic which shows the reference | standard taking-out mechanism of FIG. It is a perspective view which shows the three-dimensional circuit board obtained.
