Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an adhesive tape sticking device for sticking an adhesive tape on a flat surface and a bottom surface of a substrate used for a laminated printed circuit board or the like. It is an object of the present invention to improve the durability period of a pressing member for sticking and to keep the pressing force on an adhesive tape always average.

[Conventional technology]

Generally, when a wiring hole is to be formed in a board or the like (hereinafter simply referred to as "board") used for a printed circuit board, etc., it is adhered and sandwiched by a bakelite plate or aluminum plate in which a plurality of boards are laminated, and an adhesive tape It is affixed so as to straddle in a U-shape in the thickness direction, and the wiring hole is precisely drilled without producing burrs.

Then, in the above-mentioned hole making step, the sticking of the adhesive tape is mainly performed manually. Therefore, there is a problem in that the bonding strength varies, and when the bonding strength is weak, burrs are generated on the substrate during drilling.

Further, an adhesive tape sticking device has also appeared, but there are problems that the device becomes large and the sticking speed is slow.

Therefore, the applicant of the present application has previously proposed in order to improve the above problems, Japanese Utility Model Application No. 60-137144 (Japanese Utility Model Application No. 62-44866).
In order to provide a pressure-sensitive adhesive tape device for a laminated plate, which has a high application speed and is simple.

As a result, the adhesive strength of the adhesive tape becomes constant, and the effect of shortening the adhesive time can be obtained.

[Problems to be solved by the device]

However, some problems were still found in the actual work of the above utility model. That is, the pair of rollers forming the pressing member are supported by the elastic plate pressing arm that is bent in the middle of the length direction. Therefore, while repeatedly press-fitting a large number of laminated plate bodies,
It was found that the pressing arm supporting the roller was broken in a short period of time in addition to metal fatigue (specifically, about 8 hours a day of operation resulted in breakage in about 1 week).

Further, since the pressing member is a roller, in the step of adhering the adhesive tape to the laminated plate body, the glue residue protruding from the pressure-bonded tape adheres to the roller surface, and gradually the roller presses the adhesive tape surface. Not even,
The result was that the adhesive strength of the tape was weakened.

[Means for solving the problem]

Therefore, the present invention is provided in order to solve the above-mentioned conventional problems and to achieve the object of the invention, and the present invention is, in an adhesive tape sticking apparatus, a front and back surface of a laminated plate body in which a plurality of plate-shaped materials are laminated. In order to press the laminated plate body when it is press-fitted, a pair of pressing members supported by an elastic material, and when the pressing member and the laminated plate body are separated, the pressing member and the laminated plate body. Between the feeding mechanism for feeding the adhesive tape in a predetermined length in the thickness direction of the laminated plate body and the pressing member and the laminated plate body, the laminated plate body is placed between the pair of pressing members. In order to cut the pressure-sensitive adhesive tape at an appropriate position when press-fitting and pressing the pressure-sensitive adhesive tape with the pressing member so that the pressure-sensitive adhesive tape is pressure-bonded to the outer surface of the laminated plate body so as to straddle the U-shape in the thickness direction In the configuration consisting of the cutter provided, the flat side of the laminated plate body is pushed. A slender elastic rubber plate and a stainless steel thin plate adhered to at least one side of it to form a friction pinch body, and its base end is fixed to the upper or lower part of the moving block together with the receiving plate material, and its length is a convex arc part. While forming it, the other end is slidably attached to the lower or upper part of the moving block, the friction pinching body is interposed near the pressing member, and a knife-type cutter is attached slightly behind the convex arc surface. It is a thing.

[Action]

Explaining the operation based on the above means, first, when the laminated plate body or the friction pinching member and the roller type pressing member are moved, the roller type pressing member moves backward against the spring and moves to the bottom surface of the laminated plate body. The pressure-sensitive adhesive tape is pressed, and the friction pinching body slides while pressing the pressure-sensitive adhesive tape against the flat surface side of the laminated plate body. As a result, the adhesive tape straddles the edge of the laminated plate body in the thickness direction, and is adhered to the plane, side face, and bottom face thereof.

The convex arcuate portion of the friction pinch member is elastically deformed by pressing against the laminated plate side, and becomes a small arc shape along the small arc surface of the receiving member. Alternatively, the other end attached to the upper part extends rearward.

The surplus portion of the tape after adhesion is cut by the advance of the cutter, and one process is completed.

[Effect of device]

Since the present invention is configured as described above, in an adhesive tape sticking device capable of automatically sticking an adhesive tape to a laminated plate body by one rotation of a drive motor, the adhesive tape is for pressing the adhesive tape to the laminated plate body. Since the friction pincer has a composite structure consisting of an elastic rubber plate and a stainless thin plate, the convex arc portion smoothly bends and deforms along the press contact portion of the laminated plate body due to the flexibility of the rubber when pressed, and the adhesive tape is formed. It can be frictionally slid and can be reliably adhered with a uniform pressure.

By providing a stainless steel thin plate on the surface of the friction pinching body that contacts the adhesive tape and the laminated plate, the coefficient of friction of the surface is small, and therefore the sliding is smooth even when the adhesive tape or the laminated plate is contacted. There is no fear of scratching.

In addition, the stainless thin plate described above can provide long-term durability even after repeated bending deformation.
The results have been obtained after operating for at least 3 months and at most 6 months. Further, since a material that is a metal and has an extremely thin plate thickness is used, it is well adapted to the elastic deformation of the rubber plate, and appropriate flexibility and rigidity can be obtained.

Further, the friction pinch member and the receiving portion provided inside the convex arcuate portion can always hold the bending pinch member in an appropriate state along the small arcuate surface at the tip thereof.
