Description

[Detailed Description of the Invention] "Industrial application field" This invention is applied to a film such as a flexible copper foil laminated on an electronic circuit, a printed wiring board laminated with a solder resist film, or the like. The present invention relates to a laminating apparatus used for manufacturing a reinforced plate glass in which a synthetic resin film is sandwiched and stuck inside a plate glass.

"Problems to be solved by conventional techniques and devices" Conventionally, when laminating a film such as a flexible copper foil on an electronic circuit or laminating a solder resist film on a printed wiring board, the circumference of the core metal The one that supports a normal rubber roll coated with a heat-resistant rubber layer on a normal bearing that does not vibrate is used, but in such a roll, if the electronic circuit has a delicate pattern,
There is a drawback that the pressure bonding force does not sufficiently act and the copper foil is laminated with air bubbles and air layers left on the bonding surface of the copper foil unless it is processed without a vacuum device.

Further, there is known a plate glass whose strength is strengthened by sandwiching a synthetic resin film between two plate glasses, and as a conventional method for producing a strengthened plate glass, an adhesive agent is applied to both sides on the lower plate glass. A method is used in which the applied synthetic resin film is adhered, and the upper plate glass is placed on the synthetic resin film in a water tank or in a vacuum suction device, and water or air between them is pressed or pressed while sucking and removing water or air. .

However, in such a conventional method for producing a laminated glass for strengthening synthetic resin film, the process is complicated and the work efficiency is low, and a large-scale water tank or a vacuum suction device for vacuum bonding without leaving bubbles inside is required. However, there is a problem that a large amount of equipment cost and running cost are required.

[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, the present invention supports a roller in which uniform and minute spherical beads are densely arranged in a coated rubber layer on a bearing, and A vibrating body with a large vibration force and amplitude and a constant vibration direction, especially a recently developed pneumatic hammer is attached via a compression spring to create a circuit board with a delicate circuit pattern and a tempered glass plate that easily causes bubbles. In contrast, the strong vibration of the bearing by the vibrating body and the vibration pressing force by the bead layer with minute irregularities act closely on the laminate film to ensure even and even gaps in delicate circuit patterns such as electronic circuits. The present invention proposes a laminating apparatus capable of being pressed and favorably laminated and pressure-bonded without leaving bubbles.

"Embodiment" An embodiment of the present invention shown in the drawings will be described below.
The roll 1 has a metal core 2 around which a thin adhesive layer 3 made of heat-resistant or super-heat-resistant rubber is coated.
A bead layer 4 in which a large number of beads having a heat resistance and rigidity such as heat resistant glass and ceramics having a diameter of about 1 mm or less are closely and evenly adhered is provided on the bead layer 4. A surface rubber layer 5 made of heat resistant rubber or the like is coated.

Then, on the bearings 6 that support the support shafts at both ends of the roll 1, a vibrating body 7 having a large vibration force and a large amplitude and having a constant vibration direction in the vertical direction is attached. It is designed to be able to rotate while applying strong vibrations (frequency 100 to 500 times / minute) up and down.

As such a vibrating body 7, a pneumatic hammer capable of changing amplitude and frequency by vibrating by recently developed and commercially available compressed air and adjusting the displacement by a flow rate adjusting valve. In the illustrated embodiment, this is the most suitable, and the embodiment using this is shown.

If necessary, a weight is attached to the vibrating body 7 to increase the vibrating force.

A support body 9 is attached to the tip of the vibrating shaft 8 of the vibrating body 7, and the bearing 6 is fitted in the guide holes 10 provided on the four circumferences of the support body 9.
A plurality of vertically extending guide rods 11 are inserted and are locked by stoppers 12 at their upper ends.

A compression spring 13 is mounted around the guide rod 11 between the bottom surface of the support 9 and the upper end of the bearing 6, and the vibration shaft 8
Is transmitted to the bearing 6 via the compression spring 13.

The bearing 6 is slidably mounted vertically in a guide groove 15 provided in a side plate 14 such as a side wall of the laminator body, and is a piston of an air or hydraulic cylinder 17 mounted in a cylinder bracket 16 fixed to the side plate 14 or the bottom plate of the laminator body. The cylinder 17 is connected to a rod 17 'and is configured to slide up and down by the cylinder 17. When the laminator is used, a constant air pressure or hydraulic pressure is applied to the cylinder 17 to keep the expanded state, and the bearing 6
The roll 1 is lightly pressed onto the lower non-vibrating roll 1'through the.

The non-vibrating roll 1'uses a general rubber roll whose both end support shafts are supported by ordinary fixed bearings 6 ', but it may be a bead type roll similar to the roll 1 if necessary.

The rolls 1 and 1 ′ can be configured such that a heat source such as an electric heater or an induction heating coil is installed inside the core metal 2 as necessary, and the laminate film is laminated while being heated.

"Operation of device" Between the roll 1 and the roll 1'configured as described above,
For example, when a laminated board such as a copper foil having a delicate circuit pattern is passed together with a flexible laminate film such as a solder resist film (solder fusion prevention film), the vibrating force of the vibrating body 7 passes through the compression spring 13. Transmitted to the bearing 6,
Since the bearing 6 is elastically supported by the cylinder 17 so as to be vertically vibratable, the roll 1 vibrates strongly in the pressing direction while rotating, and the vibration pressing force due to the fine irregularities of the uniform bead layer 4 is applied. Together, they act evenly and surely on the delicate copper foil and its fine gaps, and it is possible to satisfactorily laminate the air in the gap while leaving almost no air layer on the adhesive surface.

In addition, when laminating a printed circuit board with upper and lower flexible laminating films such as dry film resist (photo-etching photosensitive film), etc., or pressure-bonded laminating of reinforced plate glass with synthetic resin film sandwiched between two plate glasses. In this case, the roll 1 can also perform good lamination without leaving air bubbles in the adhesive surface by the same action.

When used in such a laminating process, the thickness from the core metal 2 to the surface of the surface rubber layer 5 is different in the case of a heating roll, although it may be slightly different depending on the diameter of the beads, the material of the surface rubber layer 5 or the pressure applied. Most preferably, it is about 3 mm.

[Advantage of Invention] As described above, according to the present invention, a bead layer formed by closely adhering minute spherical beads having rigidity is provided on the adhesive layer covering the core metal, and the bead layer is formed on the bead layer. Since the roll coated with the surface rubber layer is supported on the bearing that receives the vibration force up and down by the vibrating body that vibrates strongly with a large amplitude in the vertical direction, the strong vibration of the bearing by the vibrating body and the bead layer The vibration pressing force due to the fine unevenness uniformly and sufficiently acts on the delicate copper foil by etching and its fine gaps, or the laminated surface, leaving air layers and bubbles while steadily pushing out the air in the gaps of the adhesive part. It becomes possible to laminate very well without any need.
