Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a squeegee as a bonding tool for bonding an adhesive film to an adherend,
In particular, the present invention relates to a pressure-sensitive squeegee that can confirm that a necessary pressure is applied for applying a pressure while applying an adhesive film in a dry manner such as a window frame of an automobile.

[0002]

2. Description of the Related Art In recent years, an adhesive film has been applied instead of painting. Because this adhesive film needs to be strongly adhered for a long time,
Pasted while applying pressure. Since this work is a fine work, it is performed manually using a squeegee, but the pressure applied to the squeegee is likely to be uneven or insufficient, and the film will be insufficiently bonded or partially non-bonded There was a disadvantage that there were cases.

[0003]

The inventors of the present invention have conducted intensive studies to solve the above-mentioned drawbacks, and as a result, have been working while confirming whether or not a pressure higher than a required constant pressure has been applied. The present inventors have found that by performing the method, the film can be stably and efficiently adhered to a complicated portion such as a window frame of an automobile, and have reached the present invention. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pressure-sensitive squeegee capable of confirming a pressure higher than a required pressure in order to securely and efficiently adhere an adhesive film.

[0004]

SUMMARY OF THE INVENTION The above objects of the present invention are as follows.
In a squeegee for attaching an adhesive film to an adherend, the squeegee is a display, a power source, a substrate having a handle and a pressure-sensitive portion, and at least one side of at least one surface of the pressure-sensitive portion serves as a fulcrum at an end of the substrate. An opening and closing plate that opens and closes via an elastic body, and
This is achieved by a pressure-sensitive squeegee characterized by having a pair of electrical contacts so as to make contact with the open / close plate and the substrate when both are closed.

[0005] The elastic body is preferably an elastic body adjusted so that the electrical contact body comes into contact when a pressure of 0.1 kg / cm or more is applied. Further, it is preferable that a cushion material and a cloth material are sequentially provided on the outside of the substrate and the opening / closing plate of the pressure sensing unit, and the display body is preferably a light emitting body.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIG. 1 showing the appearance of a pressure-sensitive squeegee according to the present invention, FIG. 2 showing an outline of the internal structure, and FIG. The substrate 1 of the pressure-sensitive squeegee of the present invention is a square plate having a size that can be easily operated with one hand, and is made of synthetic resin such as polyethylene resin, polyvinyl chloride resin, polypropylene resin, or metal. Although not particularly limited, it is preferable to use a lightweight synthetic resin having high strength. Its size depends on the application,
When used for car window frames, about 15 cm wide x
It is about 10 cm long. The corners are liable to cause injury or breakage, so it is preferable to remove them as appropriate.

[0007] The substrate 1 is provided with a handle portion 2 held by hand during use.
And the pressure-sensitive part 3, and actual sticking is performed at the tip of the pressure-sensitive part. At least one surface of the pressure-sensitive portion 3 of the substrate 1
An opening / closing plate 9 having one end fixed to the substrate 1 and the other end openable and closable is provided. The fixing portion 10 of the opening / closing plate 9 can be made via a hinge, a string, a pin, or the like. The same material as the substrate 1 can be used as the material of the opening / closing plate 9.

An elastic body 11 is provided between the substrate 1 and the opening / closing plate 9 so that the opening / closing plate 9 can be used when not in use.
Is opened, and when a pressure of, for example, 0.1 kg / cm or more, preferably 0.1 to 10 kg / cm is applied, the opening / closing plate 9 and the substrate 1 are closed so that the electrical contacts come into contact with each other. The strength of the elastic body 11 is adjusted. Elastic body 1
The arrangement 1 may be appropriately designed depending on the use of the squeegee. The pressure value is a value obtained by dividing the pressure applied to the opening and closing plate of the squeegee by the width of the squeegee in contact with the adhesive film 14. A coil spring is usually used as the elastic body 11, but is not limited thereto.
For example, a leaf spring can be used.

The substrate 1 and the opening / closing plate 9 are electrically connected to each other by an electrical contact
Is provided, and the display 7 and the power supply 8 are connected so as to display that the electric contact body 12 comes into contact.
The display 7 may be a light-emitting body such as a light bulb, a light-emitting diode, or a liquid crystal display panel, or a sounding body such as a buzzer or an oscillator such as a vibrator. The power source 8 is not particularly limited,
For example, a dry battery can be used. When the substrate 1 or the opening / closing plate 9 is electrically conductive, the substrate 1 or the opening / closing plate 9 also serves as the electric contact body 12, so that it is not necessary to provide the electric contact body 12 again.

The display 7 and the power supply 8 may be incorporated in the pressure-sensitive squeegee main body of the present invention, or may be provided separately from the main body. When incorporated in the squeegee main body, it is preferable to use a combination of a light emitting diode and a button battery in terms of visual confirmation, miniaturization, and life.

When a cushion material 13 such as urethane foam resin or foam silicone resin is provided outside the opening / closing plate 9, the squeegee surface can be easily brought into close contact with the film during use. Further, in the present invention, it is preferable that the pressure-sensitive portion 3 be covered with the cloth material 4 so that a defect such as a scratch does not occur on the surface of the pressure-sensitive adhesive film 14 when the pressure-sensitive adhesive film 14 is pressed. As a result, the squeegee itself is hardly damaged. It is preferable to use a silk cloth as the cloth material from the viewpoint of improving the surface friction during use and improving workability. If necessary, the entire handle 2 and pressure-sensitive portion 3 may be covered with a cushion material or a cloth material.

FIG. 3 is a conceptual diagram showing a method of using the pressure-sensitive squeegee of the present invention. The pressure-sensitive squeegee of the present invention has a state in which the contact side ends of the substrate 1 and the opening / closing plate 9 are open and have a gap when no pressure is applied. Disappears, the substrate 1 and the opening / closing plate 9 are closed, and the electrical contacts 12 are in contact with each other. Accordingly, by moving the pressure-sensitive squeegee along the upper surface of the adhesive film 14 while applying a constant pressure to the adhesive film 14 on the side of the opening / closing plate 9 of the pressure-sensitive portion 3, the display 7 is displayed and the operator can operate normally. It is possible to confirm whether or not a proper operation is performed, and the adhesive film 14 is securely adhered to the adherend 15.

[0013]

When the pressure-sensitive squeegee of the present invention is used, the display 7 is displayed when the pressure-sensitive squeegee is applied while pressure is applied so that the pressure-sensitive adhesive film 14 can be securely applied. Is not displayed, the appropriate pressure can be maintained and secured irrespective of the physical condition and individual differences, and the operator can confirm by himself whether or not he or she is working normally. Therefore, there is no need to put a mental burden on the worker, and no defect occurs on the film surface.
Work efficiency is also improved. Further, by using the pressure-sensitive squeegee of the present invention, the worker can acquire an appropriate pressure for attaching the adhesive film 14 to the adherend 15 in a short time.
