Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape sticking jig.

[0002]

2. Description of the Related Art Various sticking jigs have been developed and already used for sticking an adhesive tape to a flat sticking surface reliably and efficiently. However, a jig for sticking an adhesive tape to a sticking surface composed of a curved surface and a plurality of surface portions that intersect adjacently and extend in the longitudinal direction has not yet been distributed in the market.

It is well known that an adhesive tape is attached to the peripheral portion of a plate member such as a glass plate or a metal plate for the purpose of decoration and protection. Also, when two plate-shaped members are overlapped with each other and are to be connected to each other, both peripheral edges should be covered in order to join the peripheral edges to each other and seal a minute gap between them. A method of sticking an adhesive tape on is often performed. In such an application, it is advantageous that the adhesive tape is attached so as to wrap the edge surface of the peripheral portion and the plate surface adjacent to and orthogonal to the edge surface. However, as described above, since a jig capable of performing such a pasting work has not been developed, pasting has been conventionally performed manually.

A jig for efficiently attaching an adhesive tape to the edge surface of a glass plate is disclosed in Japanese Utility Model Laid-Open No. 28170/1990. The jig disclosed in this publication includes a roller that presses an adhesive tape onto an edge surface having a flat cross section, and moves the jig along the edge surface while continuously supplying the adhesive tape between the roller and the edge surface. Thereby, the adhesive tape can be accurately and efficiently attached to the edge surface having a desired length. However, this jig cannot be used for a curved surface or an adherend surface composed of a plurality of surface portions that intersect each other and extend in the longitudinal direction. Therefore, the jig cannot be used to attach the adhesive tape so as to wrap the edge surface of the glass plate and the plate surface adjacent to and orthogonal to the edge surface.

As a prior application, the applicant of the present application has already proposed a jig for sticking an adhesive tape on a sticking surface having a curved cross section, in Japanese Patent Application No. 4-145837. The jig according to this prior application includes a sticking head made of an elastic material having a sticking surface having substantially the same cross section as the sticking surface. Therefore, this jig can be used only for the adherend surface having a specific cross-sectional shape.

On the other hand, in recent years, it has been proposed to use various adhesives for joining adjacent structural members to each other and sealing the joints in the process of assembling an automobile body. As a suitable example of this kind of adhesive, JP-A-2-27
The pressure-sensitive thermosetting adhesive disclosed in JP 2076 can be mentioned. In particular, use of a tape-like sealer obtained by hardening the above pressure-sensitive thermosetting adhesive for protection of the edge portion of a vehicle body panel, rust prevention, and sealing of a small gap between mutually joined adjacent panels. Is very convenient.

When such a tape sealer is attached to the edge portions of the mutually joined vehicle body panels, the tape sealer should be attached so as to wrap around the edge surfaces of both vehicle body panels and the exposed plate surfaces adjacent to and orthogonal to them. However, it is necessary from the viewpoint of obtaining a reliable sealing effect. In this case, since a dedicated jig has not been developed as described above, the application is still performed manually.

[0008]

When manually adhering an adhesive tape to a surface to be adhered which is composed of a plurality of surface portions extending in the longitudinal direction, the adhering work is sequentially performed on each of the surface portions. Will be done. Moreover, at this time, the sticking operation must be performed while expelling the air remaining between the adhesive tape and the surface to be stuck, which consumes labor and time. In addition, when the adhesive tape has a certain degree of extensibility, it is considered that some or all of the plurality of surface portions are attached to the surface to be attached, which is a surface portion that extends in a curved shape in the longitudinal direction. To be In this case, since the sticking operation must be performed while applying the pressure required to stretch the adhesive tape by a desired amount, the sticking by hand becomes extremely difficult. Moreover, when the double-sided adhesive tape such as the tape-shaped sealer is manually attached to the curved surface to be attached, the release tape is attached to the adhesive surface of the adhesive tape that the hand touches. However, since the presence of release paper hinders the expansion of the adhesive tape,
After all, it is difficult to apply by hand.

The present invention has been devised and devised to solve the above problems in the prior art.
The purpose is to be able to attach the adhesive tape quickly and reliably to the surface to be adhered that is composed of multiple surface portions extending in the longitudinal direction, and can be used for various surfaces to be adhered that have different cross-sectional shapes. To provide a simple jig for attaching adhesive tape.

[0010]

In order to achieve the above-mentioned object, the present invention is an adhesive tape attaching jig for attaching an adhesive tape to a surface to be attached, which comprises a single groove portion extending in a predetermined direction. A support member having an opposing wall portion to be formed; and a sticking member which covers the groove portion and is installed between the opposing wall portions and which is elastically deformed while being supported by the support member and following the shape of the sticking surface. Provide an adhesive tape sticking jig.

According to a preferred embodiment, there is provided an adhesive tape sticking jig whose sticking member is made of a foam of a polymeric material. The sticking member may cooperate with the facing wall portion of the support member to form a predetermined space over substantially the entire length of the groove portion.
Further, the surface of the pasting member located on the opposite side of the groove may be extended along a predetermined curved surface. Alternatively, the opposing wall portion of the support member may extend along a predetermined curve, and the sticking member may be installed between the opposing wall portions along the predetermined curve. Further, the supporting member is made of a disc member, the groove portion is annularly extended along the outer peripheral surface of the disc member, the attaching member forms an annular space in the groove portion, and the attaching member is located on the opposite side of the annular space. The configuration in which the surface of the is extended in a ring shape is convenient because the selection range of the shape of the surface to be adhered that can use the bonding jig is expanded.

[0012]

[Operation] An adhesive tape is placed between the attaching member of the attaching jig and the surface to be attached, and a predetermined pressure is applied to the attaching member through the support member in the direction of the surface to be attached, whereby the adhesive tape is removed. Press on the surface to be attached. The adhesive member receives a reaction force from the surface to be adhered with the adhesive tape interposed therebetween, easily follows the shape of the surface to be adhered, and is elastically deformed easily in the groove of the support member.
As a result, the adhesive tape is reliably attached to the surface to be adhered regardless of the shape of the surface to be adhered.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in more detail with reference to the preferred embodiments shown in the accompanying drawings. Referring to the drawings, FIG. 1 shows an adhesive tape attaching jig 10 according to a first embodiment of the present invention. The attaching jig 10 is fixed to a supporting member 12 having a V-shaped cross section and extending in a predetermined curved shape, and an opposing wall portion 14 of the supporting member 12 extending in the longitudinal direction.
And a sticking member 16 installed between them. Support member 12
A space capable of accommodating a deformed portion of the sticking member 16 that is deformed in the sticking step is formed between the inner surface of the sticking member 16 and the sticking member 16. Further, it is convenient to fix the gripping member 18 to the support member 12 in order to improve workability during the sticking work.

The support member 12 supports the sticking member 16 and is made of a rigid material that does not deform even when the sticking pressure applied by the operator during the sticking operation is received. Suitable materials for the support member 12 include steel, stainless steel, hard plastic and the like. The support member 12 has a curved portion 24 that is curved with a predetermined curvature with the V-shaped apex portion 20 extending in the longitudinal direction as an inner arc and the end edge portion 22 of the facing wall portion 14 as an outer arc, and the curved portion 24. And a linear portion 26 that is adjacent to and linearly extends to a predetermined length. The curvature and length of the curved portion 24 and the length of the linear portion 26 may be set in accordance with the extended shape of the target surface to be attached and the length of the adhesive tape to be attached. Of course, the support member 12
It is also possible to have a shape that includes only the curved portion 24 or a shape that includes only the straight portion 26.

The sticking member 16 is made of a material that can be easily elastically deformed, and in the state without deformation, the longitudinal dimension substantially the same as the extension dimension of the facing wall portion 14 of the support member 12 and the space between the facing wall portions 14. Has a lateral dimension greater than the maximum distance.
Therefore, the sticking member 16 corresponds to the facing wall portion 1 of the support member 12.
Both edge portions 2 extending in the longitudinal direction over substantially the entire length of 4
8 is brought into contact with the outer surface of each opposing wall portion 14 and is fixed by, for example, an adhesive or a screw. As a result, the sticking member 16
The intermediate portion 30 of the support member 1 is connected via the both edge portions 28.
The two opposing wall portions 14 are arranged between the respective end edge portions 22.

In the attaching step, the attaching member 16 has its outer surface directly contacting the base material or the adhesive surface of the adhesive tape. Therefore, the sticking member 16 is required to be made of a material that is easily elastically deformed by an external force with a small stress, does not affect the properties of the base material or the adhesive surface of the adhesive tape, and has some releasability from the adhesive surface. Is. Sticking member 16
Examples of suitable materials include foamed materials such as ethylene propylene rubber, chloroprene rubber, urethane, and silicone rubber.

As an example of the step of sticking the adhesive tape by the sticking jig 10, as shown in FIG. 2, the edge surfaces 34 and 34 of the peripheral edges of the two plate-shaped members 32 placed in an overlapping manner.
The step of attaching the double-sided adhesive tape 36 so as to wrap the exposed plate surface adjacent to and orthogonal to will be described. In FIG. 2, the support member 12 and the sticking member 16 of the sticking jig 10 are shown in cross section, and the gripping member 18 is omitted in the drawing.

First, in a step, a double-sided adhesive tape 36 of a predetermined length (equal to or shorter than the length of the sticking member 16) having a release paper 38 attached to one surface thereof is attached to the sticking member 16 of the sticking jig 10. By abutting on the outer surface of the sticking member 16, the sticking member 16 is temporarily stuck and supported. Then release paper 3
8 is peeled off (step), and the adhesive tape 36 is opposed to the edge surfaces 34 of the two plate-like members 32 (step). In step, the attaching jig 10 is moved in a direction (arrow shown in the drawing) orthogonal to the edge surface 34 of the plate-shaped member 32 and the adhesive surface of the adhesive tape 36 to bring the edge surface 34 and the adhesive surface into contact with each other, and the attaching member 16 Is elastically deformed and pushed into the inner space of the support member 12. In step, when the sticking pressure is further applied to enhance the elastic deformation of the sticking member 16, the outer surface of the sticking member 16 is adjacent to the edge surfaces 34 of the two plate-like members 32 and the exposure which is orthogonal to the edge surface 34. Follow the shape of the board. At the same time, the double-sided adhesive tape 36 is attached so as to wrap the edge surface 34 and the exposed plate surface of each plate-shaped member 32 by the elastic restoring force of the attaching member 16 and the application pressure of the operator. At this time, the adhesive tape 36
Is gradually attached to the exposed plate surface from the edge surface 34 of the plate-shaped member 32, so that the residual air between the adhesive tape 36 and the adhered surface is automatically discharged. Finally, in a step, when the attaching jig 10 is separated from the plate-shaped member 32, the attaching member 1
Due to the releasability of 6, the adhesive tape 36 can be easily attached to the attaching member 16
Peel from. In this way, the sticking operation of the adhesive tape 36 is completed, and the sticking member 16 is elastically restored to the initial shape.

When the single-sided adhesive tape is attached to the surface to be attached in the attaching step, the attaching member 16 of the attaching jig 10 is used.
It is preferable to previously apply an adhesive having a releasability to some extent to the base material of the single-sided adhesive tape to the outer surface of the above.
However, when the sticking member 16 is formed of a foam of silicon rubber, the sticking member itself has the adsorptivity for temporarily holding the base material of the single-sided adhesive tape, and therefore the application of the adhesive is unnecessary. In addition, although it is common to both the single-sided adhesive tape and the double-sided adhesive tape, when the surface part to be contacted first (the edge surface 34 in the example of FIG. 2) of the adherend has an area capable of supporting the adhesive tape, Steps above ~
It is also possible to achieve the same sticking result by omitting the step and pressing the sticking member 16 of the sticking jig 10 against the sticky tape in a state where the sticky tape is placed on the surface portion in advance.

FIG. 3 shows a pressure-sensitive thermosetting material which is attached to the edge portions 42 of both panels 40 by using the attaching jig 10 in order to seal a minute gap between mutually joined adjacent panels in the body of an automobile. Tape sealer 4 made of adhesive
4 is shown. The tape-shaped sealer 44 has the form of a general pressure-sensitive adhesive tape having double-sided adhesiveness at room temperature, and thus has excellent workability. Further, when the tape is heated to a predetermined temperature after being attached to the surface to be adhered, the melt flow state is initially exhibited as the temperature rises to completely seal the surface to be adhered, and the shoulder part of the tape itself is gentle. Has a unique shape,
Eventually it cures to form a strong coating structure. The edge portion 42 of the panel 40 is the support member 12 of the attaching jig 10.
Has a curvature substantially the same as that of the curved portion 24 of the
Bend inward. The edge portion 42 curved in this way
It is extremely difficult to manually attach the tape-shaped sealer 44 to the tape sealer 44 as described above.
Also, while the residual air is automatically discharged from the adhesive interface, the tape-shaped sealer 44 can be attached in almost one operation.

FIG. 4 shows an adhesive tape attaching jig 48 according to a second embodiment of the present invention. The attaching jig 48 includes a disc-shaped support member 50, and an attaching member 52 that covers the outer peripheral surface of the support member 50 and is fixed to the support member 50. The support member 50 has a groove portion 5 extending in an annular shape along the outer peripheral surface thereof.
4, the opposing wall portion 56 of the groove portion 54 and the attaching member 52 form an annular space in the outer peripheral portion of the support member 50. The support member 50 is rotatably supported by a shaft 58 penetrating the central portion thereof, and a grip member 60 is connected to the shaft 58.

The materials of the supporting member 50 and the sticking member 52 and the operation in the sticking step are the same as in the first embodiment. According to the sticking jig 48, an endless sticking working surface is formed by the annular outer surface of the sticking member 52, so that the adhesive tape is continuously supplied between the annular outer surface of the sticking member 52 and the stuck surface. By doing so, it becomes possible to attach an adhesive tape of a desired length. Further, by operating the gripping member 60, the adhesive tape can be easily and continuously attached to the adhered surface extending in a curved shape as shown in FIG. 3 or the adhered surface extending in a meandering manner. be able to.

In each of the above embodiments, the attaching member forms a predetermined space between the attaching member and the supporting member. However, the entire space should be filled with the attaching member or another easily compressible member. You can also Further, the cross-sectional shape of the facing wall portion of the support member can be various other shapes as shown in FIGS.

[0024]

EFFECTS OF THE INVENTION As is clear from the above description, the present invention uses the restoring action of the sticking member that elastically deforms following the shape of the sticking surface to stick the adhesive tape to the sticking surface. Since it is configured, the adhesive tape can be quickly and surely adhered to the adherend surface formed of a plurality of surface portions extending in the longitudinal direction. Moreover, a common adhesive tape sticking jig can be used for various sticking surfaces having different cross-sectional shapes. If the application jig according to the present invention is used, the tape sealer can be applied to the panel edge portion quickly and reliably in the assembly process of the body of the automobile, for example.
