DETAILED DESCRIPTION OF THE INVENTION

[Detailed Description of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a method in which a cover film is wound in a vacuum on a printed circuit board sheet which is wound intermittently at a predetermined interval. The present invention relates to a method and apparatus for continuously press-bonding two or more films, sheets, and the like under high vacuum, such as when bonding while completely degassing.

[0002]

2. Description of the Related Art Conventionally, as a method of laminating two or more sheets (or films) wound and wound on two or more drums and bonding them to each other, the sheet is sandwiched between two heater rollers, and the rotational pressure is applied. In general, a method of performing pressure bonding while degassing air remaining between sheets is used. With this method, it is possible to adhere tightly with flat sheets that have nothing on the sheet surface, but for example, in the case of bonding with a circuit board sheet with an uneven surface by etching, deaeration bonding is not possible If any air bubbles remain between the sheets, a non-adhered portion is generated, which causes problems such as oxidative corrosion due to residual air and disconnection of a circuit.

[0003] In such a case, in order to perform complete deaeration, shutters that move up and down by cylinders are attached to the left and right side walls of the fixedly installed compartment, and shutter lower end surfaces that come into contact with each other when the shutters descend. O-ring, lip packing or elastic rubber is attached to the receiving surface to form a vacuum compartment, and the sheet to be bonded is intermittently fed into the room when the shutter is raised. Close and sandwich the sheet at its lower end, evacuate the room with a vacuum pump,
There is also a method in which a sheet is heated and pressure-bonded by sliding down a piston rod such as an air cylinder which is fitted into a ceiling plate of a compartment in a highly airtight manner.

However, in this method, it is difficult to seal the vacuum around the shutter. If the sheet is strongly sandwiched by the shutter, the sheet is deformed. If the sheet is weakly sandwiched, it is difficult to evacuate the sheet, and the sheet surface is stained by grease or the like. further,
Since the shutter slides up and down constantly, the seal packing around the shutter is damaged or worn, so that a high vacuum cannot be easily obtained in the compartment, and the volume of the vacuum compartment is large, resulting in a high vacuum. However, there is a problem that a large vacuum pump is inevitably required and the equipment becomes expensive.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems, and enables a high vacuum in a compartment in a short time, and a sheet such as a printed circuit board sheet wound around a drum and sent out.

Reference numerals 18 and 19 denote a pair of upper and lower take-up drums arranged on the side of the receiving table 7. A printed circuit board 18 is formed on one of the drums 18 at a predetermined interval by forming irregularities by etching or the like. Is wound around the printed circuit board sheet 20, and a cover sheet 21 having the same width for covering the printed circuit board sheet 20 is wound around the other drum 19. Numeral 21 is interposed between a pair of vertically intermittently rotating pitch feed rollers 22 disposed on the opposite side of the cradle 7 so as to be synchronized and intermittently fed onto the cradle 7. ing.

Reference numeral 23 denotes one or a plurality of conduits having one end opened on the upper surface of the pedestal 7. The conduit 23 passes through the thickness of the pedestal 7 to the other end on the side surface, and the other end. Is connected to a vacuum pump (not shown) such as an oil pump. The end of the conduit 23 on the upper surface of the pedestal 7 is pressed when the pressure contact member 16 is pressed against the upper surface of the pedestal 7.
Within the rectangular frame by the member 16 and the two sheets 20,
It is necessary to open it at a position outside the width of 21. The position where the conduit 23 is formed is not limited to the pedestal 7, but may be provided on the upper pressing block 6 and / or the sliding frame 10 if it faces the vacuum chamber 25 described later. However, the end opening must be opened at a position inside the press contact member 16 and outside the position where the sheets 20 and 21 pass, as described above.

Reference numeral 24 denotes an O-ring seal packing made of an elastic material such as rubber attached to the inner peripheral side surface of the sliding frame body 10. The seal groove into which the packing 24 fits is filled with grease for vacuum sealing. I have.

When the upper and lower sheets 20, 21 are intermittently fed into the upper surface of the receiving table 7 at the same speed by the apparatus shown in FIG. The sliding frame 10 is pulled down (see FIG. 3), and the pressure contact member 16 at the lower end of the sliding frame 10 largely surrounds the circuit-configured portions (not shown) of the sheets 20 and 21 on the receiving table 7 so as to receive from the upper surface of the sheet. The sheet is pressed against the table 7 so as to pinch and fix the front and rear of the sheet (see FIG. 4).

As a result, the sliding frame 10 is
An airtight compartment 25 surrounded by the inner peripheral surface and the lower surface of the pressing block 6 as the upper jig is formed (FIG. 4).

Then, the sheets 20, 21 on the upper surface of the cradle 7 are
The above-mentioned compartment 25 is opened by a vacuum pump such as an oil pump through an end of a conduit 23 opened at a position away from the conduit.
The inside is evacuated.

After increasing the degree of vacuum in the compartment 25 to a high degree of vacuum of, for example, 1,333 × 10 -1 kPa (1 Torr) or more, the upper press cylinder 1 is operated. To lower the pressing block 6.

When the pressing block 6 slides down on the inner peripheral surface of the sliding frame 10 while maintaining a high vacuum in the compartment 25, the space in the compartment 25 also decreases vertically, The lower surface of the contact block 6 is pressed against the sheets 20 and 21 on the receiving table 7. As described above, the pressing block 6 and the receiving table 7 are provided with the heater plates 5 and 8, respectively, and both sheets heated and pressed between the pressing block 6 and the receiving table 7 heated by the heater plates are provided. 20 and 21 are bonded by thermocompression bonding under a high vacuum without leaving any bubbles (FIG. 5).

When the lamination of the sheets 20 and 21 is completed, the interior of the compartment 25 is returned to the atmospheric pressure, and then the press cylinder 1 is reversely operated to raise the pressing block 6 and lower the pressing block 6. The cylinder 11 is also operated in the reverse direction to raise the cylinder 11 so as to follow the pressing block 6,
The upper and lower sheets 20 and 21, which have been returned to their original positions (FIG. 3) and have been bonded together, are sent to the side (to the right in the figure) by a predetermined distance and separated from the cradle 7, and the next successive sheet Is sent to the receiving table 7 and stopped, and the same bonding as described above is performed.

The apparatus shown in FIG. 1 shows an example in which a rectangular frame-shaped super-elastic pressure contact member 16 is fitted to the lower surface of the sliding frame 10. Without mounting, the above-mentioned rectangular frame-shaped superelastic press-contact member 16 is mounted on the upper surface of the receiving base 7 with which the frame body 10 contacts, so that the mounting position of the press-contact member 16 is upside down. You may do so. In this case, it is necessary to make the central portion of the upper surface of the receiving table 7 convex and slightly higher than the upper end of the pressure contact member 16 so that the sheet does not contact the member 16 until the member 16 is pressed.

Further, in the apparatus of FIG. 1, the upper surface of the receiving table 7 is a flat surface, but as shown in FIGS.
At the front and rear of the sheets 20, 21 on the upper surface of the cradle 7, linear lower press-contact members 16b made of the same superelastic material, which are longer than the lateral width of the sheets 20, 21, are also attached. The pressing member 16 of this embodiment can be pressed against the surface of the sliding frame body 10, and the lower surface of the sliding frame 10 may be changed to a combination of a linear upper pressing member 16a and a rubber seal packing 16b as in FIG. (See FIGS. 8-9).

Embodiment 2 FIG. 6 is an explanatory front view showing the entire apparatus according to another embodiment of the present invention. In this apparatus, there is no drive unit on the lower jig side, and the drive unit of the sliding frame body 10 is also provided on the upper jig side.

That is, the mounting plate 4 horizontally fixed to the lower end of the rod 3 of the press cylinder 1 horizontally suspends the supporting plate 26 to which the upper heater plate 5 and the pressing block 6 are fixed via the suspending rod 27 on the lower side. I have

Numeral 28 denotes a press-down cylinder for driving the sliding frame body 10 which is mounted downward and fixed at the center of the lower surface of the mounting plate 4, and has the same axis as the press cylinder 1 above. At the lower end of the rod 29, a pressing plate 30 is horizontally mounted and fixed.

Reference numeral 14 denotes a plurality (two or four) of connecting rods for vertically moving the above-mentioned sliding frame body 10 which is fitted to the outer periphery of the pressing block 6 so as to be vertically slidable. The upper end of each connecting rod 14 is fixed to the press-down plate 30, and the intermediate portion is fixed to the upper part of the sliding frame 10 by penetrating the upper heater plate 5 and the support plate 26. Accordingly, the sliding frame 10 slides up and down on the outer peripheral surface of the pressing block 6 via the connecting rod 14 by driving the pressing cylinder 28.

At the center of the lower surface of the sliding frame 10, a pressing member 16 made of a superelastic material such as a square frame-shaped silicon rubber as described in the first embodiment and shown in FIG. 2 may be attached. 6 and thereafter use a superelastic body such as silicon rubber, but show still another example.

That is, in order to produce a superelastic body such as silicon rubber used as the pressure contact member 16 into a rectangular frame shape as shown in FIG. 2, it is necessary to cast and mold it into a mold. However, it is not possible to cope with a change in the size of the sheets to be bonded, and preparing such press-contact members having different sizes increases the cost for the mold and other costs.

Therefore, the press-contact member is formed in advance as a linear rod-shaped member so that the press-contact member can be freely cut to an arbitrary length according to the width of the sheet to be bonded. FIG. 6 and the subsequent drawings show an example in which the airtightness of the compartment 25 is to be secured by a combination with a seal packing such as an O-ring made of an elastic body such as an elastic body.

However, in this case, the lower surface of the two sides (left and right in FIG. 6) of the thick rectangular tube-shaped sliding frame body 10 for pressing and fixing the sheets 20, 21 is slightly longer than the width of the sheet. The rod-shaped upper pressure contact members 16a, 16a made of a superelastic material such as silicon rubber having the same tip end shape as in Example 1 are fitted and fixed, and the lower surface of the same length is also placed on the upper surface of the receiving base 7 at the position facing the same. The pressing members 16b, 16b are mounted and fixed.

Numeral 31 is attached to the lower surface of the sliding frame 10 by bending it into a substantially U-shape so as to connect between the two upper pressing members 16a, 16a attached to the lower left and right surfaces of the sliding frame 10, respectively. The two seal packings made of rubber O-rings (see FIGS. 7 and 8)
From the center of the front and rear lower surfaces to the ends of the two members 16a, are fitted into seal fitting grooves 32 cut in a substantially U-shape inside and outside, and the fitting grooves 32 are filled with vacuum sealing grease.

It is to be noted that the O-ring shown in FIG.
As shown in the figure, one rod-shaped rubber seal packing 33 is bent into a substantially U-shape to form two upper pressing members 16a, 16a.
Needless to say, a single seal structure for connecting the spaces may be adopted.

On the other hand, a plate material is stuck on the center of the upper surface of the receiving table 7 or the center of the receiving table 7 is slightly protruded to form a flat mounting surface 34, and the mounting surface 34 is heated and pressed. The circuit-formed portions of the power sheets 20 and 21 are sequentially and intermittently fed. The horizontal width of the placing surface 34 (the front-rear width in the sheet advancing direction) is slightly smaller than the width of the upper pressing block 6, and the front-rear width is wider than the width of the sheets 20, 21. It is narrower than the front and rear width. An end 23 a of the evacuation conduit 23 formed in the pedestal 6 is opened at a position on the upper surface of the pedestal 6 close to one or both of the front and rear of the mounting surface 34 (only the front and rear in the figure). .

Next, the upper and lower sheets 2 by the apparatus shown in FIG.
The continuous bonding of 0 and 21 will be described with reference to FIGS. As shown in FIGS. 6 and 10, when the rods 3 and 29 of the press cylinder 1 and the press-down cylinder 28 are retracted and the pressing block 6 and the sliding frame 10 are at the upper side, the printed circuit formed at predetermined intervals. Substrate sheet 20
When the cover sheet 21 and the cover sheet 21 are intermittently sent out from the drums 18 and 19 in synchronization with each other and come to a predetermined position on the receiving table 7, first, the press-down cylinder 28 is operated to operate the sliding frame 10
(FIG. 10), and the lower ends thereof are
1 and is pressed into contact with a portion near the periphery of the upper surface of the receiving stand 7 (FIG. 11).

As a result, the two sheets 20, 21 are received by the upper pressing member 16a of a superelastic material such as silicon rubber on the lower surface of the frame 10 which is perpendicular to the traveling direction of the sheet before and after the traveling direction on the receiving table 7. The rubber packing 31 is tightly sandwiched between the lower press-contact member 16b and the lower press-contact member 16b on the upper surface of the base 7, and at the same time, a portion of the lower surface of the slide frame 10 other than the upper press-contact member 16a.
(In the embodiment shown in FIG. 9, the packing 33) is fitted, and the fitting groove 33 is also filled with grease, so that it comes into close contact with the surface of the receiving base 7 facing the same.

The packing 31 on the lower surface of the frame 10 is almost in contact with the end of the upper pressing member 16a, and a small relief groove 3 is provided beside the end of the lower pressing member 16b on the upper surface of the receiving base 7.
When the frame 10 is pressed against the pedestal 7, the upper and lower pressing members 16a and 16b are gel-like superelastic bodies, which are crushed and escape in the direction of the packing 31 and also escape into the escape groove 35. At the same time, the rubber packing 31 itself is also strongly pressed and slightly extends in the direction of the upper pressure contact member 16a, so that the upper and lower members 16a and 16b come into close contact with the tips of the packing 31 (see FIGS. 13 to 14).

In this manner, when the sheets 20, 21 are clamped and fixed by the upper and lower pressing members 16a, 16b and the lower surface of the sliding frame body 10 is tightly adhered to the upper surface of the receiving table 7 over the entire surface, the receiving table 7 An airtight compartment 25 surrounded by the inner peripheral surface of the frame 10 and the lower surface of the pressing block 6 is formed on the upper side (FIG. 11).

Then, the interior of the compartment 25 is evacuated through the conduit 23 from the end opening 23a facing the compartment 25 on the upper surface of the pedestal 7 to raise the degree of vacuum to a level higher than that of the upper and lower sheets 20 and 21 to remove air bubbles existing between the upper and lower sheets 20 and 21. While completely removing or removing, the upper pressing cylinder 1 is operated to lower the pressing block 6 in the high-vacuum compartment 25, and the two sheets 2
By heating and pressing between the receiving table 7 and the pressing block 6, the sheets 20 and 21 are thermocompressed under a high vacuum (see FIG. 12).

In the apparatus shown in FIG. 6, a rod-like member is used as a pressing member of a superelastic body, and the pressing member is moved up and down so as to coincide with each other.
Although it is attached to the lower surface and the upper surface of the cradle 7, it is also possible to omit the pressure contact member 16b on the upper surface of the cradle 7 in the apparatus shown in FIG. 6, and as shown in FIGS. The member 16 may be attached to only the lower surface of the sliding frame body 10 or may be attached to only the upper surface of the cradle 7.

As described in the first embodiment, a rubber sheet is adhered to the upper surface of the cradle 6 if necessary, covered with a silicon sheet, or a large O-ring elastic body is provided. Is also good.

The method and apparatus according to the present invention are constructed as described above, and the printed circuit board is formed at predetermined intervals, and the printed circuit board is wound in a roll and covers the printed circuit board. Conventionally, as in the case of bonding a cover sheet, it has been extremely difficult to bond a sheet having irregularities with another sheet so as to completely remove air and leave no bubbles. In the present invention, a pressure contact member made of a superelastic body such as silicon rubber or the like close to a gel is attached so as to go around the lower surface of the cylindrical sliding frame body (or the upper surface of the receiving table at a position opposed thereto), or The member is combined with an O-ring or rod-shaped seal packing made of an elastic material such as rubber, and attached so as to make a round around the lower surface of the sliding frame (or the upper surface of the pedestal opposite to the sliding frame), and the sliding frame is driven by a cylinder. Up and down By freely Pushing block other cylinder an outer circumferential surface of be configured freely closely perpendicular sliding,
First, the sliding frame is lowered to the sheet to be bonded intermittently sent at a predetermined pitch onto the receiving table, and the pressing member is pressed and fixed to the upper surface of the sheet to surround the part to be bonded. Since the chamber is evacuated and completely evacuated, then the holding block is lowered to perform the bonding, so that the holding block and the sliding frame can achieve a highly airtight compartment with a small stroke. Thus, it is possible to bond the sheets under a high vacuum, and even if the sheet has irregularities, the bonding can be continuously performed with the bubbles completely removed.

Further, in the present invention, since the sheet is sandwiched between superelastic bodies such as silicon rubber, which are almost gel-like, the lamination of a thick sheet having a thickness of 1 mm or the like can be easily performed under a high vacuum.

Further, even when a combination of the above-described superelastic pressure contact member such as silicon rubber and a rubber seal packing such as an O-ring is used, the sheet itself is pressed and fixed by a superelastic material such as silicon rubber. Since the other parts are pressed against each other with a rubber seal packing, there is no fear of soiling the sheet even if vacuum sealing grease is used for the seal packing part.

Therefore, according to the present invention, a small vacuum compartment is formed in a short time, and the sheet to be bonded is efficiently deaerated without deforming or fouling the holding portion of the sheet. It is possible to perform a continuous degassing and sticking operation.
