Hereinafter, while describing embodiment of the sticking apparatus of this invention, referring a figure, the manufacturing method of a sticking body is demonstrated. In addition, although the form shown by a figure is a preferable form of this invention, this invention is not limited.
(Attaching device)
(First form)
FIG. 1 shows a preferred first embodiment of the sticking device of the present invention. Hereinafter, with reference to the sticking apparatus 2 as appropriate, the basic form of the sticking apparatus of the present invention and the characteristic part in the first form will be described. The sticking device 2 includes a folding means 4 and a crimping means 24. In addition, the sticking apparatus 2 in this embodiment has bases 3 and 23 that can sandwich the peripheral edge 1a of the adherend 1, and the adherend is attached to the innermost part of the sandwiching portion 5 of the base 3. 1 is provided with a folding means 4 with which the peripheral edge 1a of the substrate 1 is brought into contact. A pressure-bonding means 24 is provided so as to press against.
(Folding means)
The folding means 4 has a contact portion 6 that contacts the peripheral edge 1 a of the adherend 1 covered with the film 100. The contact part 6 has a length along the peripheral direction so that the film 100 can be folded back to the base when the sticking device 2 is slid along the peripheral direction. The width should just have the thickness of the peripheral edge part 1a at least. The surface or the inside of the contact part 6 is preferably made of an elastic material that can follow the shape of the peripheral edge 1a. By doing so, the contact part 6 can be brought into close contact with the peripheral edge 1a and the film 100 can be folded back accurately and easily. Furthermore, the film 100 can be reliably folded back by making it easy for the contact portion 6 to follow along the peripheral shape of the peripheral edge 1a of the adherend 1. More preferably, the surface of the contact portion 6 has an elastic surface made of an elastic material. By having the elastic surface, the contact part 6 is pressed near the peripheral edge 1a and the contact part 6 can be brought into close contact with the vicinity, and folding and crimping can be performed reliably. As such an elastic material, for example, a foam or the like usually used for a cushion material can be used. Moreover, it can replace with the structure provided with an elastic material in the surface and the inside of the contact part 6, and can also employ | adopt the structure formed so that the folding | turning means 4 can be urged | biased to the peripheral edge part 1a side. In order to allow the folding means 4 to be biased toward the peripheral edge 1a, for example, the member including the contact portion 6 is biased toward the peripheral edge 1a using an elastic body such as a spring. Can be configured.

  The folding means 4 preferably includes a portion that abuts at least a part of the front surface and / or the back surface of the adherend that is continuous to the peripheral edge portion 1a in addition to the portion that abuts the peripheral edge portion 1a. By providing such a contact portion 7, the outer peripheral portion of the film 100 can be folded back more accurately. Therefore, as the contact portion in the folding means 4, in addition to a simple vertical wall shape that contacts only the peripheral edge 1a, an L-shape that also contacts the peripheral back surface 1b or the peripheral surface 1c, the peripheral back surface 1b, and the peripheral surface A total of three types of concave shapes that also contact 1c can be presented. In the 1st form, the part contact | abutted to the peripheral surface 1c of the to-be-adhered body 1 is provided as such an additional contact part 7, and the L-shaped contact part is comprised.

  The folding means 4 is provided in a portion (front side) preceding the pressure-bonding means 24 (specifically, the pressing portion 26) in the traveling direction in which the sticking device 2 slides the peripheral edge of the adherend 1. Just do it. Once the folded shape is imparted to the film 100 by the folding means 4, the folded shape is easily maintained (since the film 100 is at least attached to the peripheral edge portion 1a), so that the film is in that state. This is because 100 may be bonded to the peripheral back surface 1 b of the adherend 1. It is preferable that the folding means 4 is formed over the width in the direction along the peripheral edge when the sticking device 2 is applied to the peripheral edge of the adherend 1 in that the folded state is more reliably maintained. Moreover, it is preferable at the point which can move the sticking apparatus 2 bidirectionally by forming over the front-and-back of the crimping | compression-bonding means 24 along the advancing direction at the time of making the sticking apparatus 2 slide. In the first embodiment, the contact portion 6 of the folding means 4 is provided in almost the entire width along the peripheral direction of the sticking device 2, and the pressing portion 26 of the crimping means 24 is substantially in the center of the width. Is provided. For this reason, the sticking apparatus 2 is slidable in both directions. In the first embodiment, both end sides of the sticking device 2 of the contact portion 6 of the folding means 4 have curved surfaces so that the film 100 can be easily folded back, and more than the central portion of the contact portion 6. It has a configuration that protrudes toward the peripheral edge 1a side (pressure bonding means 24 side).

In the present embodiment, the folding means 4 is fixed so as not to be displaced by sliding, but the folding means 4 can be composed of one or more rotating bodies. That is, by arranging the outer peripheral surface as a member that can rotate along the peripheral direction, the sticking device 2 can be smoothly slid along the peripheral edge 1a of the adherend 1, The air (which may be a construction liquid) between the film 100 and the back surface 1c is surely expelled, and generation of wrinkles and stretches can be avoided, and the film can be adhered to the peripheral back surface 1b in a good state. Furthermore, since the rotating body can be rotated in both directions, the attaching direction can also be set in both directions, and the attaching device 2 can be attached by reciprocating with respect to the peripheral edge 1a. .
(Crimping means)
The crimping means 24 may be any one that can crimp the outer peripheral portion of the film 100 to the back surface 1 c at the peripheral edge of the adherend 1. Therefore, the press part 26 which contacts the film 100 and presses to the back surface 1c side is provided. In the relationship with the folding means 4, the pressing part 26 is in the state where the peripheral edge 1 a of the adherend 1 is pressed against the contact part 6 of the folding means 4, and the side of the peripheral back 1 b just before the peripheral edge 1 a. It is preferable that it is arrange | positioned so that can be pressed. By carrying out like this, the outer peripheral part of the film 100 folded by the folding | turning means 4 can be stuck to the peripheral edge part 1a and the peripheral back surface 1b continuous, and the film 100 can be adhered beautifully along a peripheral edge.

  It is preferable that the crimping means 24 has an elastic material at least on the surface or inside of the pressing portion 26. By having an elastic material, the film 100 can be closely adhered along the shape of the peripheral back surface 1c, and the film 100 can be reliably crimped to the back surface 1c while eliminating the entrainment of air or the like. More preferably, the surface of the pressing part 26 is formed of an elastic material and has an elastic surface.

  The effect of bringing the pressing portion 26 into close contact with the peripheral back surface 1c can also be easily obtained by the configuration in which the crimping means 6 is urged against the peripheral back surface 1b. This is because the pressing portion 26 can be brought into close contact with the back surface 1c by the pressing means 6 being biased toward the peripheral back surface 1b. Further, when the pressing part 26 is provided with an elastic material in the pressing part 26 and the pressure-bonding means 24 is urged to the peripheral back surface 1b, the film is surely provided even if there is a relatively large step on the peripheral back surface 1b. 100 can be pressure-bonded to the back surface 1c. In this embodiment, the pressing portion 26 has a configuration having an elastic surface.

  It is preferable that the crimping | compression-bonding means 24 has the site | part 27 which presses the peripheral surface 1c other than the press site | part 26 which presses the peripheral back surface 1b. That is, it is preferable to sandwich the periphery of the adherend 1. It is because the sticking device 2 can be stably held and slid with respect to the peripheral edge of the adherend 1 and can be easily pressed with an appropriate pressure when it is in the sandwiching form. In the clamping mode, the pressure for crimping can be set by the distance between the opposing members at the clamping site, or can be adjusted by the elastic force or restoring force acting between the opposing members.

  In this embodiment, the crimping means 24 has a sandwiching form, and the pressing portion 27 facing the pressing portion 26 is a part of the additional contact portion 7 of the folding means 4. And the pressing portion 27 are configured to press each other facing each other with an appropriate pressure using the restoring force of an elastic body (here, a spring body). A specific configuration for obtaining such a configuration can be appropriately designed by a person skilled in the art as needed. For example, the first base member 3 provided with the folding means 4 is used as a fulcrum for the crimping means 24. The second base member 23 can be swung with respect to the second base member 23, and the opposite side of the contact portion 6, 7 of the first base member 3 with respect to the fulcrum can be It can be configured to be fixed via the compressed elastic body 28.

  The pressing means 24 may be configured such that the pressing portion 26 is not displaced during sliding, but is preferably configured by one or two or more rotating bodies so that the pressing portion 26 rotates. In other words, the sticking device 2 is smoothly slid along the peripheral edge 1 a of the adherend 1 by arranging the outer peripheral surface as a cylindrical or columnar member that can rotate along the peripheral direction. Can be surely expelled from the air between the film 100 and the back surface 1c (which may be a working liquid), avoiding wrinkles and stretching, and sticking the film to the peripheral back surface 1b in good condition can do. Furthermore, since the rotating body can be rotated in both directions, the attaching direction can also be set in both directions, and the attaching device 2 can be attached by reciprocating with respect to the peripheral edge 1a. . In particular, it is preferable that at least one of the folding means 4 and the crimping means 24 is constituted by a rotating body. In this embodiment, the crimping means 24 is constituted by a single short columnar rotating body 24a having a circular cross section.

The sticking device 2 includes any one of the contact portions 6 and 7 of the folding means 4 and the contact portions 26 and 27 of the pressure-bonding means 24, or the peripheral edge 1a of the adherend 1 in addition to any of these. It is preferable that a portion having contact with either the peripheral back surface 1b or the peripheral surface 1c is provided with a smooth surface layer having a lower friction than other portions. By doing so, the film 100 can be easily folded and pressure-bonded, and the sticking failure can be effectively suppressed. The smooth surface layer is preferably made of a fluororesin such as polytetrafluoroethylene. Moreover, it is preferable that the smooth surface layer is provided in the immovable member which is not displaced rather than the rotating member. In the sticking apparatus 2 of this embodiment, a smooth surface layer is provided on the surfaces of the contact portions 6 and 7.
(Manufacturing method of a sticking body)
Next, a method for manufacturing an adhesive body by attaching the film 100 to the periphery of the adherend 1 using such an adhesive device 2 will be described.

  First, the sticking apparatus 2 is set with the film 100 folded back. FIG. 2A illustrates a state in which the film 100 is attached to the main adherend surface of the adherend 1 and the outer peripheral portion of the film 100 is extended from the peripheral edge 1a. The gripping part 30 of the sticking device 2 is gripped, an external force against the restoring force of the elastic body 28 is applied and the crimping means 24 side is opened, and in this state, it is extended from the peripheral edge 1a of the adherend 1. The outer peripheral portion of the film 100 is applied to the peripheral edge 1a at the contact portion 6 while the outer peripheral portion of the film 100 is folded back to the peripheral back surface 1b side of the adherend 1 using the pressing portion 26. The portion is completely folded back toward the peripheral back surface 1b side of the adherend 1, and in this state, the external force applied to the grip portion 30 is relaxed, and the first base portion 3 and the second base portion 23 are closed. The figure which looked at the state which turned over the film 100 from the side surface side is shown in FIG.2 (b). In this way, the outer peripheral portion of the film 100 is folded back at the peripheral edge portion 1 a and is crimped to the peripheral edge portion 1 a, and the pressing portion 26 of the crimping means 24 attaches the outer peripheral portion of the film 100 to the peripheral back surface of the adherend 1. The state pressed to 1b is formed. In addition, it is preferable that the position where the sticking apparatus 2 is set is preferably the substantially central part of the length of the peripheral edge to be stuck on the outer peripheral part of the film 100. By setting the central portion to fold the outer peripheral portion of the film 100 from the central portion and sticking it toward one end along the peripheral edge, and making the distance to be continuously attached about half of the entire peripheral edge. By suppressing the amount of elongation of the film 100 that occurs at the time of sticking, problems in the sticking state due to the elongation of the film 100 can be suppressed.

  Next, while holding the grip portion 30 of the sticking device 2 and pressing the contact portion 6 of the folding means 4 against the peripheral edge 1a, the sticking device 2 is slid toward the peripheral edge or one end. At this time, the abutting part 6 can fold the outer peripheral part of the film 100 to the peripheral back surface 1b at the same time as the sticking device 2 is slid, and can press the film to the peripheral edge 1a. When the contact portion 6 is provided with an elastic material or the folding means 4 is biased toward the peripheral edge 1a, the peripheral edge 1a is in close contact with the peripheral edge 1a even if the peripheral shape is curved. It is easy to wrap. Furthermore, when the contact part 6 and the contact part 7 are provided with a smooth surface layer, the film 100 can be slid in a pressed state without being damaged and without being wrinkled or twisted.

  At substantially the same time, the pressing portion 26 of the pressing means 24 presses the film 100 against the peripheral back surface 1b and presses it against the back surface 1b. When the pressing part 27 is provided, the film 100 can be reliably crimped to the peripheral back surface 1b by sandwiching the vicinity of the peripheral edge 1a. In addition, since the crimping means 24 is a rotating body that rotates with sliding along the peripheral length direction, the outer peripheral portion of the film 100 is successively folded while discharging air without causing wrinkles or the like. It is possible.

  In addition, in the sticking apparatus 2, since the crimping means 24 is provided with a structure that is pressed against the peripheral back surface 1b by the restoring force of the elastic body 28, even if the sealer is applied to the peripheral back surface 1b with a thickness, The film 100 can be pressure-bonded by absorbing the thickness or pressing the film 100 against the peripheral back surface 1c with a sufficient pressing force. Moreover, since the sticking apparatus 2 is equipped with the smooth surface layer on the surface of the contact parts 6 and 7, it can slide smoothly the peripheral edge part 1a vicinity of the to-be-adhered body 1 covered with the film 100. FIG. The film 100 can be prevented from wrinkling, stretching, and air biting.

  When the film 100 has been pasted to one end of the periphery of the adherend 1, the pasting device 2 is slid to the initial set position while holding the periphery of the adherend 1 as it is, from the set position to the other end. By sliding the sticking device 2, the outer peripheral portion of the film 100 can be continuously folded and pressed against the peripheral back surface 1b.

As explained above, according to the sticking apparatus 2, the outer peripheral part of a film can be stuck correctly and reliably along a periphery. In addition, since the attaching device 2 is simply slid along the periphery of the adherend 1, the attaching operation can be performed with high accuracy regardless of the skill level of the operation.
(Second form)
Next, a preferred second embodiment of the present invention will be described. Hereinafter, characteristic parts in the second embodiment will be mainly described. FIG. 3 shows a second preferred embodiment of the sticking device of the present invention. The sticking device 42 in this embodiment includes a folding means 44 and a crimping means 64 as in the first embodiment. The sticking apparatus 42 of this embodiment has a substantially L-shape corresponding to the peripheral edge 1a and the peripheral back 1b of the adherend 1 as a whole.
(Folding means)
The sticking device 42 of this embodiment includes base portions 43 and 63, and these base portions 43 and 63 constitute a substantially L-shape. The folding means 44 is provided on the base 43. In the sticking device 42, the folding means 44 is arranged in parallel so as to be along the peripheral direction of the adherend 1 and is composed of two independent rotating bodies 44a and 44b. Each of the rotating bodies 44a and 44b is configured to be able to rotate the sticking device 42 along the periphery of the adherend 1. The rotating bodies 44a and 44b are arranged at an appropriate interval. However, in this embodiment, the rotating bodies 44a and 44b are arranged close to each other so as not to prevent the mutual rotation. Moreover, it is preferable that the rotating bodies 44a and 44b have a cylindrical body or a columnar body shape in which the side surface is always in contact with the peripheral edge portion 1a of the adherend 1 even when rotated. In this case, each of the rotating bodies 44a and 44b has a circular cross section, and the side surfaces thereof are formed by cylindrical bodies that constitute contact portions 46a and 46b that contact the peripheral edge 1a of the adherend 1, respectively. ing. These contact parts 46a and 46b are provided with an elastic surface made of an elastic material that can closely contact and follow the shape of the peripheral edge 1a. The contact portions 46a and 46b have a width (corresponding to the height of the cylindrical body) that can sufficiently correspond to the thickness of the peripheral edge 1a, and the peripheral edge 1a and the peripheral back 1b that is continuous with the elastic surface. In addition, it can follow and include a part of the peripheral surface 1c.

  The folding means 44 is configured to be positioned further forward along the traveling direction in which the periphery slides in relation to the crimping means 64. The rotating body 44a is positioned in front of the crimping means 64 in one direction along the circumferential direction, and the rotating body 44b is positioned in front of the crimping means 53 in the other direction along the circumferential direction. As a result, the sticking device 42 can slide in both directions along the peripheral direction.

  Furthermore, each rotary body 44a, 44b is urged | attached and attached to the peripheral edge part 1a direction, and can always press the film 100 to the peripheral edge part 1a with sufficient pressing force. The rotating bodies 44a and 44b are urged with substantially the same pressing force. In order to urge the folding means 44 toward the peripheral edge 1a, for example, the elastic bodies 48a and 48b are contracted to the opposite end of the peripheral edge 1a in the hole that supports the rotating shafts 45a and 45b of the rotating bodies 44a and 44b. It is possible to adopt a configuration in which they are supported and supported.

In this sticking device 42, the folding means 44 is formed of two rotating bodies 44a and 44b, and each is independently biased toward the peripheral edge 1a side, so that the peripheral shape is a curved surface, Even if there are irregularities, the contact portions 46a and 46b can reliably follow the peripheral shape, and the film 100 can be securely adhered and pressure-bonded to the peripheral edge 1a. In addition, since the contact portions 46a and 46b of the rotating bodies 44a and 44b also have elastic surfaces, the film 100 can be more firmly adhered and pressure-bonded to the peripheral edge 1a.
(Crimping means)
The crimping means 64 is provided on the base 63 so as to cooperate with the folding means 44. The crimping means 64 is composed of a single rotating body 64a that can rotate along the peripheral direction. The crimping means 64 is a columnar rotating body 64a, and the side surface thereof is provided as a pressing portion 66 that can always press the film 100 against the peripheral back surface 1b. In this embodiment, the rotating body 64a is formed of a short cylinder having a circular cross section. The pressing portion 66 has an elastic surface formed of an elastic material. Furthermore, in this embodiment, the crimping means 64 is urged and attached in the direction of the peripheral back surface 1b, and can always press the film 100 to the peripheral back surface 1b with sufficient pressing force. That is, it protrudes from the base 63 to the peripheral back surface 1b side by a predetermined distance, and when the film 100 is attached to the peripheral back surface 1b of the adherend 1, it is against the biasing force to approximately the same surface as the surface of the base 63. Displaceable. The configuration in which the crimping means 64 is urged toward the peripheral back surface 1b in the direction of the peripheral back surface 1b is, for example, a state in which the elastic body 68 can be contracted to the opposite end side of the peripheral back surface 1b in the hole that supports the rotating shaft 65 of the crimping means 64. The structure which interposes and supports by can be taken.

  Note that the crimping means 64 is configured such that, in the sticking device 42, the center of the crimping means 64 is positioned at an intermediate portion between the two rotating bodies 44 a and 44 b provided as the folding means 44. Further, a smooth surface layer 67 is provided at the front part and / or the rear part of the base 63 along the peripheral direction of the crimping means 64. By providing the smooth surface layer 67, the peripheral back surface 1b of the adherend 1 covered with the film 100 can be smoothly slid. In addition, by providing such a smooth surface layer 47 at least in the front part along the sliding direction of the sticking device 42, the sticking part can be supplied to the crimping means 64 in a good state. If both the front part and the rear part of the peripheral edge 1a of the crimping means 64 are provided, the sticking device 42 can be easily slid along the peripheral direction. In addition, by providing such a smooth surface layer 67, the film 100 can be folded back smoothly by the folding means 44.

In this sticking device 42, since the crimping means 64 is urged toward the peripheral back surface 1b, the contact portion 66 is not in contact with the peripheral edge 1a. When the contact portion 66 is pressed against the peripheral back surface 1b with an appropriate pressure, it protrudes more toward the peripheral back surface 1b than the surface of the smooth surface layer 47 that contacts the peripheral edge 1a. The degree of urging is adjusted so that the contact portion 46 is displaced on substantially the same surface as the surface layer 47 forms. By carrying out like this, the film 100 can be stuck and stuck to the peripheral edge part 1a fully and correctly.
(Manufacturing method of a sticking body)
Next, a method of manufacturing an adhesive body by attaching the film 100 to the periphery of the adherend 1 using such an adhesive device 42 will be described.

  First, the sticking apparatus 2 is set with the film 100 folded back. FIG. 4A shows a state in which the film 100 is attached to the main adherend surface of the adherend 1 and the outer peripheral portion of the film 100 is extended from the peripheral edge 1a. As shown in FIG. 4 (b), the side of the adherend 1 to which the film 100 is attached is directed downward, and the contact portions 46a and 46b are located below the peripheral surface 1c of the adherend 1. The sticking device 42 is positioned so that the peripheral surface 1c comes into contact with the contact parts 46a and 46b, and the peripheral edge 1a comes into contact with the pressing part 66 of the crimping means 64. Move to. By doing so, the outer peripheral portion of the film 100 is bent with the peripheral edge 1a of the adherend 1 as a base.

  Next, as shown in FIG. 4C, the outer peripheral portion of the film 100 folded at the peripheral edge 1 a at the contact portions 46 a and 46 b of the folding means 44 of the sticking device 42 and the pressing portion 66 of the crimping means 64. While pressing moderately, the sticking device 42 is brought down to the peripheral back surface 1b side, and the film 100 is folded and adhered to the peripheral back surface 1b. By doing so, the contact portions 46a and 46b press and press the film 100 against the peripheral edge 1a, and the pressing portion 66 presses and presses the film 100 against the peripheral back surface 1b, thereby completing the setting. .

  Next, while holding the sticking device 42 and pressing the contact portions 46a and 46b against the peripheral edge 1a and the pressing portion 66 against the peripheral back surface 1b, the sticking device 2 is directed toward the peripheral edge or one end. Slide. In addition, it is preferable to press the sticking apparatus 42 to the peripheral back surface 1c to such an extent that it slides on the surface of the film 100 where the smooth surface layer 67 is folded. At this time, since the contact portions 46a and 46b rotate independently as they slide, the outer periphery of the film 100 is continuously and sequentially discharged while discharging air without generating wrinkles or the like. It can be folded back. Moreover, since the elastic surface is provided, the film 100 can be reliably crimped | bonded closely to the shape of the peripheral edge part 1a. Furthermore, since each is independently urged | biased at the peripheral edge part 1a side, it can follow a shape of the peripheral edge part 1a well, and can perform folding and crimping | crimping reliably.

  The pressing part 66 can press the film 100 against the peripheral back surface 1b with a sufficient pressing force by the pressing means 64 being pressed against the surface of the film 100 where the smooth surface layer 67 is folded back. Further, since the pressing portion 6 is urged toward the peripheral back surface 1b side and is provided with an elastic material, the film 100 can sufficiently follow the shape and have sufficient pressing force even if the back surface has irregularities and curved surfaces. Can be brought into close contact with each other. In the sticking device 42, since the folding means 44 is a rotating body and includes an elastic material, it is highly versatile and can be applied to various adherends 1 regardless of the thickness of the periphery. .

In addition, in the sticking apparatus 42, although the folding | returning means 44 was set as the structure which uses a rotary body, it is not limited to this, The thing which does not displace may be sufficient. Further, the folding means 44 has a vertical wall shape, but may have an L shape or a concave shape. Further, the folding means 44 has a configuration in which the rotating shaft is urged toward the peripheral edge 1a side by an elastic body and the contact portions 46a and 46b are provided with elastic surfaces. Instead of this, it is also possible to employ a configuration in which an elastic material is provided inside the contact portion. Furthermore, although the crimping | compression-bonding means 64 was made into the rotary body which has an elastic surface, it is not limited to this, It can also be set as the fixed press form which does not displace.
(Third form)
FIG. 5 shows a third preferred embodiment of the sticking device of the present invention. Hereinafter, a characteristic part in the third embodiment will be mainly described. The sticking device 82 in this embodiment includes a folding means 84 and a crimping means 104. The sticking device 82 has a plate-like base portion 83 having a slit 81 that is slidable with respect to the peripheral edge portion 1a in a state where the peripheral edge portion 1a of the adherend 1 is accommodated. Both the folding means 84 and the crimping means 104 are provided in the slit 81 of the base 83.

  The folding means 84 includes two rotating bodies 84a and 84b configured to be rotatable along the peripheral direction. The rotating bodies 84a and 84b are provided on one end side and the other end side of the slit 81, respectively, and the crimping means 104 is disposed between the rotating bodies 84a and 84b.

  Each rotating body 84a, 84b is a cylindrical body whose respective side surfaces (peripheral surfaces) form contact portions 86a, 86b. In this embodiment, the contact portions 86a, 86b are peripheral edges on the peripheral surface. A concave groove capable of accommodating the portion 1a is formed. Therefore, the contact portions 86a and 86b are in contact with the peripheral edge portion 1a and the vicinity thereof (the portions near the peripheral edge portion 1a of the peripheral back surface 1b and the peripheral surface 1c). Moreover, each rotary body 84a, 84b is formed so that it can urge to the peripheral edge part 1a side. In order to allow the rotators 84a and 84b to be biased toward the peripheral edge 1a, for example, an elastic body such as a spring in a support hole that supports the rotation shaft of the rotators 84a and 84b provided with the contact portions 86a and 86b It can comprise by making it the state urged | biased to the peripheral edge part 1a side. In addition, it is good also as a structure provided with an elastic material in the surface and inside of contact part 86a, 86b.

The crimping means 104 includes a portion 106 that presses the film 100 against the peripheral back surface 1b so that the outer peripheral portion of the film 100 can be crimped to the back surface 1c at the peripheral edge of the adherend 1. In this embodiment, the crimping means 104 is disposed between the rotating bodies 84 a and 84 b of the folding means 84. The crimping means 104 has a pressing portion 106 that can crimp the folded portion of the film 100 on the peripheral back surface 1b, and also has a peripheral edge portion 1a and a portion corresponding to the peripheral surface 1c shape continuous thereto. As a whole, a concave shape is formed so as to sandwich the vicinity of the peripheral edge 1a. Further, the entire surface layer of the concave portion of the crimping means 104 has a smooth surface layer. Furthermore, the inside of the press part 106 is equipped with the elastic material, and the press part 106 is formed so that it can be urged | biased to the peripheral back surface 1b side.
(Manufacturing method of a sticking body)
Next, a method for manufacturing an adhesive body by attaching the film 100 to the periphery of the adherend 1 using such an adhesive device 82 will be described.

  First, the sticking apparatus 2 is set with the film 100 folded back. FIG. 6A shows a state in which the film 100 is attached to the main adherend surface of the adherend 1 and the outer peripheral portion of the film 100 is extended from the peripheral edge 1a. By gripping the opposite side of the slit of the attaching device 82, the outer peripheral part of the film 100 extended from the peripheral edge 1a of the adherend 1 is attached to the contact part 86a of the rotating body 84a of the folding means 84 in the slit. To introduce. By carrying out like this, the outer peripheral part of the film 100 is return | folded by the peripheral edge part 1a at the peripheral back surface 1c side, and it can be crimped | bonded to the peripheral edge part 1a vicinity, and a setting is completed. Next, the film 100 folded at the peripheral edge 1a is pressure-bonded to the peripheral back surface 1b by sliding the sticking device 82 along the peripheral edge. As the sticking device 82 slides, the film 100 is continuously folded and pressed.

  In the sticking device 82, the rotating bodies 84a and 84b have concave contact portions 86a and 86b, respectively, so that the film 100 is folded back at the peripheral edge 1a and the film 100 is placed at and around the peripheral edge 1a. Can be crimped roughly. Further, since the contact portions 86a and 86b rotate as the sticking device 82 slides, the film 100 can be smoothly folded back and crimped near the peripheral edge 1a. Therefore, wrinkles, twisting, and air biting of the film 100 are suppressed in the vicinity of the peripheral edge 1a. Furthermore, since the rotating bodies 84a and 84b are urged toward the peripheral edge 1a side by the elastic body, they follow the shape of the peripheral edge 1a and reliably contact the film 100 along the peripheral edge 1a. Can be folded and crimped. In particular, in the present embodiment, the two rotating bodies 84a and 84b are provided. However, since each of the rotating bodies 84a and 84b rotate independently and are independently biased toward the peripheral edge 1a, the shape of the peripheral edge 1a is a curved surface. Even if it has irregularities, it can cope with it sufficiently.

  Moreover, since the crimping | compression-bonding means 104 has a concave shape corresponding to the peripheral edge part 1a vicinity, the film 100 turned up | folded reliably can be crimped | bonded also to the peripheral edge part 1a other than the peripheral back surface 1b. Moreover, since this concave-shaped crimping | compression-bonding means 104 is equipped with the smooth surface layer on the surface, it suppresses generation | occurrence | production of a wrinkle, expansion | extension, an air bite, etc. in the folded film 100. FIG. Furthermore, since the pressing part 106 is urged | biased by the peripheral back surface 1b side, even if the pressing part 106 has uneven | corrugated shape on the peripheral back surface 1b side, the press part 106 can be closely_contact | adhered to the peripheral back surface 1b corresponding to it. It is possible and secure crimping is possible.

  In addition, in the sticking apparatus 82, although the folding | returning means 104 was set as the structure which uses a rotary body, it is not limited to this, You may be fixed without being displaced. Moreover, although the folding | returning means 104 was made into the concave shape, it may be a vertical wall shape or L shape. Further, the folding means 104 has a configuration in which the rotating shaft is biased toward the peripheral edge 1a side by an elastic body, but this configuration is not necessarily required, and the surface of the contact portion is replaced with the configuration or together with the configuration. Or the structure which equips the inside with an elastic material is also employable. Furthermore, although the crimping | compression-bonding means 104 was made into the concave shape, it is not limited to this, It can also be set as the structure only of the press part pressed on the peripheral back surface 1b. Moreover, although the crimping | compression-bonding means 104 was made into the fixed form which does not displace, it can also be comprised as a rotary body.

  As explained above, according to the bonding apparatus and the manufacturing method of the bonded body of the present invention, the outer peripheral portion of the film can be bonded accurately and reliably along the periphery, and defective bonding can be effectively suppressed. . And since it only slides along the peripheral edge part of a to-be-adhered body, hold | gripping a sticking apparatus, a sticking operation | work can be performed with high precision irrespective of the skill level of work.
