Abstract

PROBLEM TO BE SOLVED: To provide a method for manufacturing an exterior panel, capable of efficiently spreading a film or the like to bond the same. SOLUTION: A process (1) for arranging the film 35 of the adherend surface 23 of the panel 20, a process (2) for pressing a part of the film 35 to the adherend surface 23 in a dotted or linear form to closely bond the film 35 to the adherend surface 23 and a process (3) for forming a new pressure region 37 while displacing the same from the aforementioned pressure region over an equal distance to expand the closely bonded region of the film 35 and the adherend surface 23 are provided, and the film 35 is spread to the almost whole of the adherend surface 23 to be bonded thereto. In this method, since the new pressure region is formed while displaced from the dotted or linear pressure region over an equal distance, an excess part is hardly generated in the expansion direction of the closely bonded region. Accordingly, the film can be spread and bonded at a stroke while the generation of air bubbles between the film and the adherend surface is suppressed and the panel having the film bonded thereto in a spread state can be efficiently manufactured.

2. Description of the Related Art In order to apply a design having different colors between an upper portion and a lower portion on an outer surface of an automobile body, one (mainly, upper) color is colored by ordinary painting, and the other color is a body. It may be colored by spreading a sheet-like film on the outer surface. It is important that such a film be stuck to the surface to be adhered without bubbles or wrinkles between the film and the outer surface of the body. In order to suppress the generation of bubbles and wrinkles, the work of attaching a film to an adhered surface such as the outer surface of a car body is performed by humans. However, usually, the surface to be adhered is not a flat surface, but often has a curved surface, a step, or the like, so that the work requires skill. Also, in general,
Due to the long working time required for film spreading, it is difficult to make a line in combination with other manufacturing processes.

Forming a film while displacing the film, and enlarging a contact portion between the film and the adherend surface, and spreading the film over substantially the entire adherend surface.

In this method, since a new pressed portion is formed at the same distance from the pressed portion, a surplus portion is unlikely to be generated in the enlargement (forming) direction of the contact portion. Therefore, in the present method, a panel on which a film or the like is spread can be manufactured by suppressing wrinkling of the film or generation of bubbles between the film and the adherend surface.

Further, there is provided the panel manufacturing method, wherein the steps 2) and 3) are each performed once. In this method, since steps 2) and 3) are performed only once, the generation of wrinkles and air bubbles from one end to the other end of the film is suppressed, and a panel on which the film is spread is manufactured. be able to. Further, since the film can be spread by only one operation, the efficiency is high.

Further, in any one of the above manufacturing methods,

[0013]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. The method for manufacturing a panel on which a film or the like according to the present invention is spread includes: 1) a step of arranging a film on an attachment surface of the panel; and 2) attaching a part of the film in a dot shape or a line shape. 3) a step of forming a new pressed portion while displacing the pressed portion at an equal distance from the pressed portion, and enlarging a portion where the film and the bonded surface are in close contact with each other; Wherein a film is spread over substantially the entire surface to be adhered.

FIGS. 1 and 2 schematically show a part of an embodiment of the manufacturing method of the present invention. FIG. 1 shows a step of tightly fixing the film 5 to the panel 1 in a developed state,
FIG. 2 is a side sectional view of FIG. The panel 1 is a member used for exterior or interior of various articles such as building materials and vehicles, and is typically a plate-like member such as an outer panel of a vehicle. The manufacturing method of the present invention is generally suitable for large panels. The panel 1 is preferably formed in a substantially flat surface, but may be provided with a groove or a step, or may be formed in a curved surface. Part or all of the panel 1 is formed on the adhered surface 3. The adherend surface 3 is a film 5
Is a portion that is closely fixed in a deployed state.

The film 5 is formed in a sheet shape, and is formed in substantially the same shape as the surface 3 to be adhered.
The film 5 can be a film having various functions according to its use, and for example, a coated film can be used. Various dry or wet adhesives are applied to the back surface of the film 5 as in the related art. In the present production method, it is preferable to provide a dry adhesive which does not require a medium such as water or a surfactant.

According to the present manufacturing method, the film 5 is applied to the panel 1.
In order to spread the film, first, the film 5 is arranged on the attachment surface 3 of the panel 1 (step (1)). At least a part of the film 5 is arranged at a predetermined position on the adherend surface 3 so that its adhesive surface faces the adherend surface 3. The portion opposed to the adherend surface 3 may be anywhere on the film 5, but is preferably an end or an edge. For example, as shown in FIG. 1A, the upper edge 7 a of the rectangular film 5 can be arranged to face the upper edge of the adhered surface 3.

Next, a part of the film 5 is pressed in a dot-like or linear manner against the adherend surface 3 to bring the film 5 into close contact with the adherend surface 3 (step (2)). The pressing shape may be a dot shape or a linear shape, and the shape may take various shapes. If it is linear, it is preferably linear. The close contact can be performed by various forms of pressing. For example, a spreading member formed in a rod shape or a plate shape may be pressed, or may be pressed directly by hand. Alternatively, it may be performed by spraying a liquid or gas such as water or air controlled in a predetermined spraying shape at a predetermined pressure. FIG. 1 (a), FIG.
(A) shows a state in which the film 5 is pressed against the adhered surface 3 to form a pressed portion 9.

Next, a new pressing portion is replaced with the pressing portion 9 described above.
The film 5 is formed while being displaced at the same distance from, and the contact portion between the film 5 and the adherend surface 3 is enlarged (step (3)). The new pressing part 10 is continuously formed at the same distance from the pressing part 9. That is, as shown in FIG. 1, the contact portions are sequentially formed at the same distance from the pressing portion 9. Therefore, as shown by the arrow in FIG. 1B, the contact portion between the film 5 and the adherend surface 3 is continuously enlarged from a portion adjacent to the pressing portion 9 to a portion far from the pressing portion 9.

In this step, the pressing is preferably performed in such a manner that the film 5 is constantly pressed against the adherend surface 3 with a uniform pressure and that the film 5 can be continuously moved on the adherend surface 3. For this reason, it is preferable that the adhesion in this step is performed by a method in which the film 5 is pressed against the adhered surface 3 by a long spreading member formed in a linear shape or an arc shape. Alternatively, a method of pressing the film 5 against the adherend surface 3 by spraying a liquid or gas such as water or air into a predetermined shape (linear, circular, or arc shape) may be used.

Further, for example, in a mode in which the spreading member is pressed, the spreading member may be formed in a movable shape while rotating on the film 5, and may be moved and pressed while rotating on the film 5. ,preferable. When pressed in this manner, it is possible to prevent a gap from being formed between the film 5 and the adhered surface 3 and to prevent an excess portion from being generated between the immediately-adhered portion and the next-adhered portion of the film 5, and thus, it is preferable. The film 5 can be brought into close contact with the adherend surface 3 in a developed state. The cross-sectional shape of the spreadable member can be formed in a circular shape, an elliptical shape, a chamfered polygonal shape, or the like. A circular shape is preferable because it can be pressed with a uniform pressure.

When a new pressing portion 10 is formed, it is preferable that the film 5 immediately before contact is held in a developed state. For this reason, it is preferable that the portion of the film 5 before being adhered, that is, the non-adhered portion is pulled in a direction away from the adhered surface 3.

By pressing the film 5 over substantially the entire surface 3 to be adhered, the film 5 can be brought into close contact with the surface 3 to be adhered. After that, by performing a process such as folding each edge of the film 5 to the back side of the panel 1, a film spread portion can be formed on the panel 1. Here, if necessary, the film 5 is completely adhered to the adhered surface 3 by leaving it for a predetermined time or the like. In the film spread portion, the error of the close contact position of each portion of the film 5 is small, and the generation of a surplus portion is favorably suppressed. For this reason, it is a film spread portion in which generation of wrinkles and bubbles is suppressed well. Also, (2)
When the film is spread by performing the step (3) only once, the film can be spread all at once because the close contact to the correct position is completed only by pressing each film portion once. In addition, if the film is accurately positioned first, the film can be spread without confirming that the positional relationship between the new contact portion and the adherend surface is correct, so that the work is simple and efficient.

The form of forming the pressed portion and the form of forming the contact portion of the present invention are not limited to the above embodiment.
If the pressed portion is provided at a portion other than the edge or the end of the film, that is, at the center portion, the entire film is spread by moving the pressed portion in a plurality of directions to form a new contact portion. May be. In this case, the step of forming a new contact portion by simultaneously pressing in all directions (the step (3)) may be performed only once, or separately pressing in different directions from the first pressed portion. (Step (3)) may be performed a plurality of times. In addition, a plurality of contact portions may be provided for one film. In this case, it is preferable to perform ((3) step) at least once for each contact portion.

FIGS. 3 (a) to 3 (c) show an example in which the first pressed portion (step (2)) has a different form. When the first pressed part is formed in a dot shape, the new pressed part can be formed in an arc, a circle, or a straight line. When the first pressed part is formed in a dot shape, it is preferably formed at the center of the film. For example, FIG.
As shown in (a), the first pressed part is formed at the center of the film, and the new pressed part can be continuously formed in an arc shape or a circle equidistant from the dot. At this time, it is preferable that the diameters of the arc and the circle are continuously enlarged.

In the case where the first dot-shaped pressing portion is provided at the end or near the edge of the film, the new pressing portion is
It may be formed in an arc shape, or may be a line shape that moves substantially parallel to the same distance from an imaginary line passing through the first pressed portion. For example, as shown in FIG. 3B, the first pressed portion is formed in a dot shape at the end (corner) of the film 5, and a new linear pressed portion can be formed from the pressed portion. .

When the first pressed portion is formed in a linear shape, various shapes such as a straight line, a curved line, and a wavy line can be selected, but it is preferably formed in a linear shape or an arc shape. Then, the new pressed portion is formed in a substantially identical linear shape parallel to the line of the first pressed portion. That is, new pressing parts are continuously formed at equal distances toward both sides of the film. For example, as shown in FIG. 3 (c), a pressed portion is formed in the center of the film 5 in a straight line parallel to the short side of the film 5, and a new pressed portion is formed from the pressed portion in both short side directions. It can be formed in a straight line displaced by a distance.

Next, one embodiment of the film spreading member according to the present invention will be described. FIG. 4 shows a film spreading member according to an embodiment of the present invention. The film spreading member 40 has a long roller 42 and a shaft 44. The roller 42 is formed in a cylindrical shape. Roller 42
Is a part which comes into contact with the outer surface of the film and presses the film against the adhered surface. The roller 42 is preferably formed to have a width corresponding to the size of the film to be spread. For example, if the film is rectangular, the rollers 42
Are formed at least longer than the short sides of the rectangle.

The roller 42 includes a roller base 45 and the elastic body 4.
6. It is preferable that the roller base 45 has a predetermined rigidity and is formed to be slightly elastically deformable. Although it can be formed in various cross-sectional shapes such as a polygon, an ellipse, and a circle, it is preferably a circle.

The elastic body 46 is provided so as to cover the entire outer peripheral surface of the roller base 45, and forms the outer peripheral surface of the roller 42. The elastic body 46 is an elastically deformable member, and may be, for example, a foam such as a sponge, rubber, or the like. By providing the elastic body 46, the outer surface of the roller 42 can be brought into close contact with the uneven surface or curved surface of the adhered surface. The thickness of the elastic body 46 is 5 mm or more and 3 mm or more.
When it is 5 mm or less, it is possible to favorably conform to the uneven shape or curved surface of the outer surface of the panel.

The shaft body 44 is a roller base 45 of the roller 42.
Is provided so as to be inserted loosely into the inside of the. Shaft 44
Is a long member having a cross-sectional area smaller than the cross-sectional area of the hollow portion of the roller base 45, and is movable in the internal space of the roller base 45. The shaft body 44 can have various cross-sectional shapes similarly to the roller base 45. Also, the shaft 4
The cross-sectional shape of 4 may be the same as or different from the shape of the roller base 45. If the shaft body 44 is formed in a circular cross section, the frictional force with the roller 42 is small, and it is difficult to hinder the rotation of the roller 42. In the present embodiment, the shaft body 44 is formed to have a length protruding from both ends of the roller 42. With this arrangement, it is easy to hold the shaft body 44 by hand or a machine and to move the shaft body 44 on the surface to be adhered.

Here, it is preferable that the ratio between the outer diameter of the shaft body and the inner diameter of the roller base 45 be 2:10 to 9:10. In this range, by pressing the outer peripheral surface of the roller 42 against the film and pressing the roller 42 toward the adhered surface with the shaft 44, the roller 42 can be pressed linearly at the roller 42 contacting the shaft 44. If the shaft body 44 is too small with respect to the inner diameter of the roller base 45, the roller 42 will not be stable, and the pressing position will not be stable. If the outer diameter of the shaft body 44 is larger than the inner diameter of the roller base 45, the rotation of the roller 42 becomes difficult. More preferably, the outer diameter of the shaft body 44 and the roller base 4
The ratio of the inner diameter of 5 is 4:10 to 6:10.

Therefore, for example, the inner diameter of the roller 42 (the inner diameter of the roller base 45) is 50 mm, and the outer diameter of the shaft is 2 mm.
When the thickness of the elastic body 46 is 5 mm and the thickness of the elastic body 46 is 10 mm, the elastic body 46 can favorably conform to the uneven shape and the curved surface of the adherend surface, and can be stably pressed with a uniform pressing force.

Next, a method of manufacturing a panel on which a film or the like is spread using the spreading member 40 will be described. FIG. 5 is a view of a vehicle door panel, which is a panel according to an embodiment of the present invention, as viewed from the exterior side. The upper and lower portions of the door panel 20, including the portion where the window frame 21 is formed, are color-coded. The upper part is colored by normal painting. The lower part is colored by the film 35 being spread.

In order to spread the film 35 on the surface 23 of the door panel 20 using the spreading member 40, first, FIG.
As shown in (a), the entire upper edge of the film 35 is arranged on the upper edge of the attachment surface 23 of the door panel 20. In the present embodiment, the upper edge of the film 35 is attached to a predetermined position (upper edge) of the adhered surface 23 by the temporary fixing member 51.

In this embodiment, the lower edge of the film 35 is locked by the clip 54 so that the surface
It is pulled in the direction away from. The clip 54 is connected to a position separated from the attachment surface 23 by an elastic member 52.

Next, as shown in FIG. 6B, the spreading member 40 is pressed against the temporarily fixed portion of the film 35 to form a pressed portion 37. The spreading member 40 presses the shaft 44 inserted through the inside of the roller 42 toward the surface 23 to be adhered. With this operation, the film 35 can be strongly pressed against the adherend surface 23 along the shaft 44 on the outer surface of the roller 42, that is, the outer surface of the elastic body 46. By this pressing, a pressing portion 37 is formed. At this time, the shaft 4
Reference numeral 4 is disposed at a position eccentric to the adhered surface 23 with respect to the axis of the roller 42. The elastic body 46 is elastically compressed and deformed by pressing.

Thereafter, as shown in FIG.
4 is moved along the adhered surface 23. At this time, the shaft body 44 remains in an eccentric position with respect to the roller 42. Further, the shaft body 44 may be moved in parallel with the adherend surface 23 without rotating. The roller 42 rotates and moves while pressing the film 35 against the adherend surface 23 in accordance with the movement of the shaft body 44. The roller 4 is pressed by the shaft body 44.
The film 35 pressed to the adhered surface 23 via the second member 2 closely adheres to the adhered surface 23, and the adhered portion is enlarged. For this reason,
By forming the pressing portion 37 with the main spreading member 40 and continuously moving it along the adhered surface 23 as it is, a new pressing portion is formed while being displaced at an equal distance from the initial portion.

Here, the shaft body 44 has such a strength that the elastic body 46 is compressed and deformed to such an extent that the elastic body 46 conforms to a shape other than a flat surface such as a fine uneven shape or a gentle curved surface of the attachment surface 23.
It is preferable to move in a state where it is pressed in the direction. When the spreading member 40 is moved in such a pressed state, the outer surface of the roller 42 can be favorably aligned with each part of the panel 1, and the film 35 can be pressed and adhered.

For example, FIG. 7 shows a state in which a concave groove 25 extending parallel to the axis of the spreading member is formed on the surface 23 to be attached. When the spreading member 40 is disposed in this portion, the elastic body 46 that is compressively deformed tries to return to the original thickness in the groove 25 portion, enters the groove 25, and
Abuts on the adherend surface 23 forming. For this reason, the film 35 is pushed into the groove 25 by the elastic body 46, and is further pressed against and adheres to the portion of the adherend surface 23 where the groove 25 is formed.

The same applies to the case where the adherend surface 23 is formed as a curved surface that is curved in the axial direction of the spreading member 40. The elastic body 46 that has been compression-deformed can follow the concave or convex surface of the adherend surface 23 in a good contact state by changing the amount of compression. Therefore, the film 35 can be pressed against the curved adherend surface 23 and can be closely attached. In addition, in the spreading member that spreads the film on the surface of the spreading member 40 that is curved in the axial direction, it is preferable that the roller base 45 be formed to be elastically deformable. When formed in this manner, the outer surface of the roller 42 can more favorably follow the curvature of the spreading member 40 in the axial direction.

Since the spreading member 40 is formed in a linear shape, it is displaced at an equal distance from the linear pressing portion only by moving the shaft member 44 along the mounting surface 23 with both ends thereof. In addition, a new linear pressing portion can be formed. Since the shaft body 44 is not directly in contact with the film 35 but via the roller 42, even if the shaft body 44 is moved along the adhered surface 23 in a pressed state, an extra force is applied between the shaft body 44 and the film 35. Does not join. Further, since the roller 42 moves while rotating, it can move smoothly on the film 35. Therefore, in the spreading member 40, the shaft 4
4, while pressing the film 35 against the adherend surface 23 with a strong force, the first pressed portion 37 is smoothly passed through the roller 42.
A new pressing portion can be formed at an equal distance from the pressing portion.
For this reason, the film can be spread at a stretch by a simple operation, and the working time can be shortened.

The outer peripheral surface of the roller 42 is
It is formed with. For this reason, the film 35 can be pressed against the adherend surface 23 with a strong pressing force by the shaft body 44, and can follow the uneven shape of the adherend surface 23, so that the film 35 can be closely attached. Further, the roller 42
Is rotated, so that a load is not easily applied between the film 35 and the elastic body 46, and the film is easily spread. Also,
Before the film 35 is securely pressed to and adhered to the adherend surface 23 at the shaft body 44, the film 3
5 can be maintained in an expanded state, and it is easy to suppress the generation of wrinkles and bubbles.

Further, it is also easy to form a pressing portion at one end of the film 35 and move the new pressing portion to the opposite end by pressing the spreading member 40 against the pressing portion. Therefore, if this exhibition wearing member is used,
With one spreading operation, the entire film can be spread all at once.

In the spreading member of the present invention, a pressing assisting portion can be provided. The pressing assist portion is a member that can press the intermediate portion of the roller toward the surface to be adhered. The film can be pressed against the adherend surface with a more uniform pressing force over the entire axial direction of the roller 42.

FIG. 8 shows a spreading member 60 provided with a pressing auxiliary portion 62 according to the present invention. The spreading member 60 is
Since this is a modification of the spreading member 40 according to the first embodiment of the present application, the same members are denoted by the same reference numerals, and description thereof will be omitted. The press assisting section 62 has a pressing roller 64 and a grip section 66. The pressing auxiliary portion 62 is fixedly connected to both ends of the shaft body 44 protruding from the roller 42 by a connecting member 68.

The pressing roller 64 is arranged so as to come into contact with the outer peripheral surface of the central portion of the roller 42, and its rotating shaft 65 is parallel to the shaft 44. The outer peripheral surface of the pressing roller 64 has rigidity. The grip part 66 is a part that a person holds by hand and applies a pressing force. The grip 66 is disposed on the side facing the roller 42 with the pressing roller 64 interposed therebetween. The grip portion 66 is connected and fixed to a rotating shaft 65 of the pressing roller 64 by a connecting member 69.

When the spreading member 60 is used, the shaft 4
4 is moved along the surface to be adhered.
While holding the second gripper 66 by hand, the pressing roller 64 presses the roller 42 so as to press it. Thereby, the roller 4
The central portion of 2 presses the adherend surface more reliably, and the film can be satisfactorily adhered to the adherend surface. Press roller 64
Is rotatable, so that it does not prevent the roller 42 from rotating.

FIG. 9 shows another modification. In the spreading member 80, the pressing auxiliary portion 82 is provided directly on the shaft 44 so that the central portion of the shaft 44 can be pressed.
The pressing assisting portion 82 includes a long grip portion 84,
A gripping portion 84 is provided by a connecting member 86 extending from both ends thereof.
Are fixed to the central portion of the shaft body 44 in a protruding state so as to be parallel to the shaft body 44. On the other hand, the roller 42 is divided into three in the axial direction, and a connecting member 86 is arranged between the divided surfaces. Also in this spreading member 80, the shaft 4
By pressing the gripping portion 84 by hand and pressing in the direction of the adhered surface while moving the roller 4 along the adhered surface, the pressing force at the central portion of the roller 42 can be made more reliable.

In any of the spreading members, a resistance layer can be provided on the outer surface of the elastic body 46 in order to increase the frictional resistance between the film and the outer surface of the roller. The resistance layer is provided on the outer peripheral surface of the elastic body. It is preferable that the frictional force between the film and the resistance layer is formed in such a size that the roller can move while rotating on the film surface. The resistance layer can be a rubber or plastic film, a woven fabric, a knitted fabric, or the like.
It may have a network structure such as a polyurethane net. By providing the resistance layer, the wear of the elastic body can be suppressed.
