Description

Technical Field

[0001] The present invention relates to an adhesive application jig and an adhesive application method.

Background Art

[0002] In the building field, as exterior materials for structures (such as curtain walls), glass building materials that are excellent in various performances such as daylighting properties, design properties, and fire resistance are widely used. Glass exterior materials are constructed by adhesive application (sealant application) in which adhesive is filled into joints, in order to ensure design properties, airtightness and durability. In adhesive application, it is necessary to inject the adhesive into the joint while supporting the glass building material.

[0003] For example, as disclosed in Patent Document 1, a sealant placing method is known in which a gap provided between a peripheral edge portion of glass and a frame body supporting the peripheral edge portion of the glass is filled with a sealant from the out-of-plane direction of the glass.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in conventional adhesive application, when a support metal fitting is adhered to the vicinity of the central portion of a glass exterior material (point support adhesion construction method), it is necessary to temporarily fix the angle material arranged along the joint of the glass exterior material with a tool such as a clamp arranged at the peripheral edge portion of the glass exterior material, which leads to the problem of poor workability. In addition, in conventional adhesive application, there is a problem that the angle material used for temporary fixing becomes an obstacle to the adhesive injection work, which causes a reduction in construction quality.

[0006] This invention has been made in consideration of these circumstances, and aims to provide an adhesive application jig and adhesive application method that offer good workability and construction quality. [Means for solving the problem]

[0010] An adhesive application jig according to an embodiment of the present invention will be described with reference to Figures 1-9. In this embodiment, the drawings are schematic diagrams for easy understanding of the configuration, and the dimensional ratios of each component may differ from those of the actual components.

Within the depth direction Y, the side in which the Y-axis arrow points is the rear side Y1, and the side opposite to the direction in which the Y-axis arrow points is the front side Y2. Furthermore, the view from the depth direction Y is defined as the "front view".

[0011] As shown in Figures 1 and 2, the adhesive application jig 1 is a jig that assists in the application of adhesive (point support adhesive method) to the application section 52 of the object 5 and the object to be applied 6 placed on the application section 52. Figure 1 is a front view showing the adhesive application jig 1 according to this embodiment. Figure 2 is a plan view showing the adhesive application jig 1 according to this embodiment. The adhesive application jig 1 includes a support part 2 and a pressing part 3.

[0012] As shown in Figure 1 to Figure 2, the object 5 is, for example, an elongated plate-shaped member made of glass used for constructing curtain walls, to which the workpiece 6 is adhered by adhesive application. The object 5 is arranged to face the pressing direction Z. The object 5 includes a supported surface 51 and an application portion 52.

[0013] The supported surface 51 is the surface on the side where the adhesive application jig 1 is arranged, among the surfaces of the object 5. In the present embodiment, the supported surface 51 is formed in a planar shape orthogonal to the pressing direction Z. On the supported surface 51, the suction portion 21 of the support portion 2 to be described later is arranged.

[0014] The application portion 52 is the part of the object 5 where the workpiece 6 is applied (adhered), and is a groove or opening formed in the central portion (other than the peripheral edge portion) of the surface of the object 5. The application portion 52 is fixed to the workpiece 6 after the adhesive is injected in a state where the workpiece 6 is arranged, and then the adhesive is cured.

[0015] Note that the shape, material and configuration of the object 5 are not particularly limited as long as they involve adhesive application. Although the object 5 exemplifies a glass exterior material where adhesive application is frequently used, it may also be an exterior material such as an aluminum composite panel or a CFRP (carbon fiber reinforced plastic) panel constructed by adhesive application. Further, the object 5 is not limited to an exterior material, and may be an interior material that constructs a ceiling surface, a floor surface, an interior wall surface, and the like.

[0016] As shown in Figure 1 to Figure 3, the workpiece 6 is, for example, a pin-shaped support hardware that supports a glass exterior material. Figure 3 is a cross-sectional view showing a state where adhesive is injected into the workpiece 6 according to the present embodiment. The workpiece 6 is arranged in the application portion 52 of the object 5, and is fixed to the application portion 52 by adhesive application. The workpiece 6 includes a contact surface 61, an opposing surface 62, an injection hole 63, an elastic ring 64, a filling space (space) 65, and a peripheral surface 66.

[0017] The contact surface 61 is one of the planar portions formed on the upper side Z1 (the side away from the object 5) of the object 5, which is substantially parallel to the supported surface 51 of the object 5, and is the portion that comes into contact with the adhesive application jig 1. The contact surface 61 is formed in a circular shape that is larger than the pressing surface 321 of the pressing portion 3, which will be described later, when viewed from above.

[0018] The peripheral surface 66 is the other side of the planar portion formed on the upper Z1 side of the object to be worked on 6, which is substantially parallel to the supported surface 51 of the object 5, and is the portion that does not come into contact with the adhesive application jig 1. The peripheral surface 66 is formed below the contact surface 61 Z2 and along the periphery of the contact surface 61.

[0019] The opposing surface 62 is a planar portion formed on the lower side Z2 of the object to be constructed 6, facing the supported surface 51 of the object 5. The opposing surface 62 corresponds to the back portion of the contact surface 61 and the peripheral surface 66. In other words, the opposing surface 62 is a plane having the same periphery as the peripheral surface 66 in a plan view.

[0020] The injection holes 63 are the parts that guide the adhesive from the outside of the workpiece 6 toward the filling space 65. The injection holes 63 are holes formed along the pressing direction Z, and multiple holes are formed on the peripheral surface 66. The upper end Z1 of the injection holes 63 does not interfere with the adhesive application jig 1 because the peripheral surface 66 does not come into contact with the adhesive application jig 1. The lower end Z2 of the injection holes 63 is in communication with the filling space 65.

[0021] The elastic ring 64 is an annular member positioned along the periphery of the peripheral surface 66 and is formed of an elastic material such as rubber. The elastic ring 64 is provided so as to be elastically deformable along the pressing direction Z. The upper end Z1 of the elastic ring 64 is in contact with the peripheral surface 66. The lower end Z2 of the elastic ring 64 is in contact with the supported surface 51 of the object 5.

[0022] The filling space 65 is the space between the workpiece 6 and the object 5 into which the adhesive is filled. The filling space 65 is sealed so as to be surrounded by the opposing surface 62, the elastic ring 64, and the supported surface 51. The interior of the filling space 65 is filled with adhesive through the injection hole 63.

[0023] Furthermore, the shape, material, and composition of the object to be worked on (6) are not particularly limited, as long as they involve adhesive application. The object to be constructed 6 is exemplified as a support fitting used in the construction of glass exterior materials that are frequently applied using adhesive, but other configurations are also possible. For example, the object to be constructed 6 may be a member that supports ancillary equipment such as handrails or electronic equipment, or it may be a decorative member that is placed to improve the aesthetic appearance. Furthermore, the object to be worked on 6 may have any configuration as long as it is supported by the adhesive application jig 1 and the adhesive can be filled into the bonding area. For example, the contact surface 61 may have a shape that engages and fits with the adhesive application jig 1, and is not limited to a flat surface. Also, the object to be worked on 6 may not have an elastic ring 64.

[0024] As shown in Figures 1, 2, and 5, the support portion 2 is the part that connects the adhesive application jig 1 and the object 5. Figure 5 is a front view showing the support portion 2 of the adhesive application jig 1 according to this embodiment. The support portion 2 is the part that bears the reaction force F caused by the pressing force P generated by the pressing portion 3. The support portion 2 is equipped with a plurality of suction portions 21 and connecting portions 22. In this embodiment, two suction portions 21 are arranged along the width direction X.

[0025] The suction part 21 is a part having a suction cup-like structure, for example, similar to a suction cup, and is provided so as to be able to adhere to the supported surface 51 of the object 5. The suction part 21 comprises a suction cup 211, a suction body 212, a suction lever 213, and a suction frame 214.

[0026] The suction cup 211 is the part that contacts the supported surface 51 of the object 5, and is formed in a suction cup shape from an elastic material such as rubber. The upper end Z1 of the suction cup 211 is located inside the suction body 212 and is connected to the end of the suction lever 213 on the suction body 212 side. The lower end Z2 of the suction cup 211 is positioned to protrude further down Z2 than the lower end Z2 of the suction body 212.

[0027] The suction body 212 is the main body portion of the suction unit 21 and is made of, for example, a steel component. The suction body 212 is formed in a circular shape that is larger than the suction cup 211 when viewed from above. Inside the suction body 212, a groove-shaped arrangement space (not shown) is provided on the lower Z2 side where the suction cup 211 is positioned. In addition, a hole (not shown) is formed in the central part of the suction body 212 when viewed from the front, communicating with the arrangement space, and a part of the suction lever 213 is inserted through it.

[0028] The suction lever 213 is the part that presses the suction cup 211 downward Z2 and is formed in a shape that allows it to be gripped. One end of the suction lever 213 on the suction body 212 side is inserted through a hole formed in the center of the suction body 212 and connected to the upper end Z1 of the suction cup 211. The suction lever 213 is provided to be rotatable along the circumferential direction with a rotation axis in one direction (depth direction Y in this embodiment) intersecting the pressing direction Z, for example, by pin connection to the suction body 212. The suction lever 213 rotates toward the side away from the pressing part 3 (see Figure 8) and presses the suction cup 211 downward Z2. When the suction cup 211 is pressed by the suction lever 213 while in contact with the supported surface 51 of the object 5, it elastically deforms with the pressure, and the air inside the suction cup 211 is released to the outside, causing a decrease in internal pressure and exerting an adhesive force (a force opposite to the reaction force F).

[0029] The suction frame 214 is a connecting member, for example made of steel, that connects the suction body 212 and the connecting portion 22. The suction frame 214 is formed integrally with the suction body 212. The suction frame 214 is provided on the pressing portion 3 side of the suction body 212 and is formed in a shape that extends to the upper side Z1 of the suction body 212. In plan view, the suction frame 214 is formed from three plate-like members that form a roughly U-shape and is positioned so as not to overlap with the rotation of the suction lever 213. The end of the suction frame 214 on the pressing portion 3 side is connected to a rotary joint 222, which will be described later.

[0030] The connecting portion 22 is a connecting member, for example, made of steel, that connects multiple suction portions 21. The connecting portion 22 is formed in the shape of a single rod extending along the width direction X. In the width direction X, an insertion portion (support side connecting portion) 221 is formed in the center of the connecting portion 22. Also in the width direction X, a rotary joint 222 is provided at each end of the connecting portion 22.

[0031] The insertion portion 221 is the connection portion between the support portion 2 and the pressing portion 3, and is formed in the shape of a female screw that penetrates along the pressing direction Z. The insertion portion 221 is fastened to the shaft portion (shaft-side connection portion) 31 of the pressing portion 3, which will be described later.

[0032] The rotary joint 222 is the connection portion between the suction part 21 and the connecting part 22, and is a joint that is rotatable along the circumferential direction with the width direction X as the axis of rotation. One end of the rotary joint 222 on the pressing part 3 side is connected to the end of the connecting part 22 in the width direction X. The other end of the rotary joint 222 that is separated from the pressing part 3 is connected to the end of the suction frame 214 on the pressing part 3 side. Therefore, the suction part 21 and the connecting part 22 are rotatably connected along the circumferential direction with the width direction X as the axis of rotation.

[0033] The shape, material, and configuration of the support portion 2 are not particularly limited, as long as they can support the reaction force F caused by the pressing force P applied by the pressing portion 3 to the workpiece 6. The support section 2 is configured to support the adhesive application jig 1 by adhering two suction parts 21 to the supported surface 51 of the object 5, from the viewpoint of stability and work efficiency, but other configurations are also possible. For example, the support section 2 may be configured to support the adhesive application jig 1 with a single suction part 21 having high suction force. In that case, attaching and detaching the suction part 21 becomes even easier, improving work efficiency. Alternatively, for example, the support section 2 may have three or more suction parts 21. In that case, the adhesive application jig 1 is supported even more stably, improving workability. Furthermore, although the support unit 2 is configured to allow the suction force of the suction cup 211 to be controlled by the suction lever 213, the suction lever 213 does not necessarily have to be present, and other configurations are also possible. For example, the support unit 2 may exert suction force when an operator presses the upper surface Z1 of the suction body 212. Alternatively, the support unit 2 may be connected to a depressurization device, for example, via an air hose, and exert suction force by reducing the pressure inside the suction cup 211. Furthermore, the support portion 2 is equipped with a rotary joint 222 to exert suction force without being affected by unevenness (manufacturing errors) of the supported surface 51 of the object 5, but the rotary joint 222 does not have to be provided, and other configurations are also possible. For example, the support portion 2 may be configured to be able to attract multiple supported surfaces 51 extending in different directions by connecting the suction portion 21 and the connecting portion 22 with a universal joint that can move in three dimensions.

[0034] As shown in Figures 1, 2, and 4, the pressing portion 3 is the part that generates a pressing force P to press against the object to be worked on 6. Figure 4 is a front view showing the pressing portion 3 of the adhesive application jig 1 according to this embodiment. The pressing portion 3 comprises a shaft portion 31 and a flexible contact portion 32.

[0035] The shaft portion 31 is a rod-shaped member, for example, made of steel, that extends along the pressing direction Z, and is formed in a male thread shape. The shaft portion 31 is inserted into and fastened to the insertion portion 221. At the upper end Z1 of the shaft portion 31, a shaft apex portion 311 is formed, which is a portion that does not have a thread shape.

[0036] The shaft top portion 311 is a part formed integrally with the shaft portion 31. The shaft top portion 311 has a hole that penetrates in one direction perpendicular to the pressing direction Z (width direction X in Figure 1). The handle portion 312 is inserted through the hole in the shaft top portion 311.

[0037] The handle portion 312 is a member that extends in one direction perpendicular to the pressing direction Z (width direction X in Figure 1) and is formed in a shape that allows it to be gripped. The handle portion 312 is provided so as to be rotatable along the circumferential direction with the pressing direction Z as the axis of rotation. When the handle portion 312 rotates toward one side in the circumferential direction, the shaft portion 31 moves downward Z2 due to its engagement with the insertion portion 221. Conversely, when the handle portion 312 rotates toward the other side in the circumferential direction, the shaft portion 31 moves upward Z1 due to its engagement with the insertion portion 221.

[0038] The adjustable contact portion 32 is a rotatable (displaceable) steel member, such as a rotating washer, provided at the lower end Z2 of the shaft portion 31. The upper end Z1 of the adjustable contact portion 32 is connected to the lower end Z2 of the shaft portion 31. A pressing surface 321 is formed at the lower end Z2 of the adjustable contact portion 32.

[0039] The pressing surface 321 is the surface located at the lower Z2 end of the pressing part 3 and is the part that comes into contact with the contact surface 61 of the workpiece 6. In plan view, the pressing surface 321 is formed in a circular shape that is smaller than the contact surface 61. The pressing surface 321 moves in conjunction with the forward and backward movement of the shaft part 31 (rotation of the handle part 312). When the pressing surface 321 is in contact with the contact surface 61, its further downward Z2 movement is stopped by the contact surface 61, thereby generating a pressing force P on the workpiece 6.

[0040] The shape, material, and configuration of the pressing portion 3 are not particularly limited, as long as it is supported by the support portion 2 and can generate a pressing force P to press against the workpiece 6. The pressing part 3 is lightweight and requires little work, and generates the pressing force P by a screw structure, but other configurations are also possible. For example, the pressing part 3 may be configured to generate the pressing force P by equipment such as a hydraulic cylinder and an electric actuator. Furthermore, the pressing portion 3 is designed to effectively generate a pressing force P even when the pressing surface 321 is not directly facing the pressing direction Z, due to the rotation of the freely movable contact portion 32. However, the contact portion may not rotate. For example, the lower end Z2 of the pressing portion 3 may have a spherical contact portion, or it may be a contact surface made of an elastic material. Even with these configurations, the pressing portion 3 can effectively generate a pressing force P.

[0041] The adhesive application jig 1 of this embodiment, configured as described above, can apply the object to be applied 6 to the application portion 52 of the object 5 by the adhesive application method shown in Figures 6-8. Figure 6 shows the contact step S1 in which the contact surface 61 of the object to be applied 6 is brought into contact with the pressing surface 321 of the pressing portion 3. Figure 7 shows the arrangement step S2 in which the suction portion 21 of the support portion 2 is placed on the supported surface 51 of the object 5. Figure 8 shows the pressing step S3 in which a pressing force P is generated on the object to be applied 6.

[0042] The contact process S1 is the process of bringing the contact surface 61 of the object to be treated 6 into contact with the pressing surface 321 of the pressing part 3, as shown in Figure 6. First, the worker places the object to be treated 6 on the treatment part 52 of the target object 5. Next, the worker operates the handle part 312 so that the pressing surface 321 of the pressing part 3 is located below Z2 below the suction cup 211 of the suction part 21. Next, the worker positions the adhesive application jig 1 so that the pressing surface 321 of the pressing part 3 comes into contact with the contact surface 61 of the object to be treated 6. After the contact process S1 is completed, the process moves on to the placement process S2.

[0043] The placement step S2 is the step of positioning the suction part 21 of the support part 2 to the supported surface 51 of the object 5, as shown in Figure 7. The operator operates the handle part 312 while maintaining the pressing surface 321 of the pressing part 3 in contact with the contact surface 61 of the object 6 to be worked on, and moves the suction part 21 of the support part 2 to a position where it contacts the supported surface 51 of the object 5. After the placement process S2 is completed, the process moves on to the pressing process S3.

[0044] The pressing step S3 is a step in which a pressing force P is generated on the object to be treated 6, as shown in Figure 8. First, the worker rotates the suction lever 213 of the suction part 21 away from the pressing part 3, causing the suction cup 211 of the suction part 21 to adhere to the supported surface 51 of the object 5. The adhesive application jig 1 stands stably on the supported surface 51 due to the suction force of the suction cup 211. Next, the worker operates the handle part 312 to move the pressing surface 321 further downward Z2. At this time, the pressing surface 321 generates a pressing force P toward the object to be treated 6 because the downward movement force toward Z2 is locked at the contact surface 61. Here, since the adhesive application jig 1 is connected to the supported surface 51 by a suction force that is greater than the reaction force F (force toward upward Z1) caused by the pressing force P, no displacement toward upward Z1 occurs, and the object to be treated 6 can be pressed. The object to be worked on, 6, is stably supported on the work area 52 by receiving a pressing force P from the adhesive application jig 1. After the pressing process S3 is completed, the process moves on to the injection process (not shown).

[0045] The injection process, as shown in Figures 3 and 8, involves injecting adhesive into the filling space 65 of the workpiece 6 supported by the adhesive application jig 1. While the workpiece 6 is supported (pressed) by the adhesive application jig 1, the worker fills the filling space 65 with adhesive through the injection hole 63. At this time, since the pressing surface 321 is smaller than the contact surface 61, and a working space (a space that does not interfere with the adhesive application jig 1) is provided above the injection hole 63 Z1, the worker can easily fill the adhesive. The adhesive application jig 1 continues to support (press) the workpiece 65 until the adhesive filled in the filling space 65 hardens. Once the adhesive filled in the filling space 65 has completely hardened, the workpiece 6 is bonded to the workpiece 52, and the adhesive application is completed. After the adhesive application is completed, the worker operates the handle 312 and the suction lever 213 to remove the adhesive application jig 1 from the workpiece 5. After the injection process is completed, the process moves on to the contact process S1 for the next construction area.

[0046] The configuration of the adhesive application jig 1 and the adhesive application method are not particularly limited, as long as they can be used to fill the filling space 65 with adhesive while supporting the object to be applied 6 with a pressing force P. The adhesive application method exemplified here is one in which the positioning step S2 is performed after the contact step S1, as this allows for the omission of the positioning step. However, the contact step S1 may be performed after the positioning step S2. In that case, the worker can perform the contact step S1 after the positioning step S2 by clearly defining the location where the suction part 21 should be placed in advance, for example, by marking lines on the supported surface 51.

[0047] As described above, the adhesive application jig 1 of this embodiment is an adhesive application jig 1 that supports an object to be applied 6 to be adhered to the application portion 52 of an object 5, and comprises a support portion 2 having a suction cup-shaped suction portion 21, and a pressing portion 3 connected to the support portion 2, in contact with the object to be applied 6 placed on the application portion 52, and pressing in the pressing direction Z which is the direction from the suction portion 21 toward the object 5.

[0048] The adhesive application jig 1 according to this embodiment can be placed at any position on the supported surface 51 of the object 5 and can effectively support the object 6, thus offering better workability compared to the temporary fixing devices used in conventional adhesive application (point support adhesive construction). Furthermore, since the adhesive application jig 1 has a working space (a space that does not interfere with the adhesive application jig 1) above the injection hole 63 Z1, it does not hinder the adhesive injection work and contributes to improved construction quality.

[0049] Furthermore, in the adhesive application jig 1 according to this embodiment, the shaft portion 31 is a male thread shape extending along the pressing direction Z and is inserted into and fastened to an insertion portion 221 formed in the shape of a female thread. A handle portion 312, which can rotate along the circumferential direction with the pressing direction Z as the axis of rotation, is inserted into a hole in the shaft top portion 311 which is formed integrally with the shaft portion 31. When the handle portion 312 rotates along the circumferential direction, the shaft portion 31 moves forward and backward along the pressing direction Z. As a result, the adhesive application jig 1 is lightweight and easy to construct, yet can generate a pressing force P to support the object to be applied 6. In addition, since the pressing force P of the adhesive application jig 1 is generated by the operator rotating the handle portion 312, it does not require a prime mover or other device, and is easy to maintain. Therefore, the adhesive application jig 1 has better workability and is easy to construct, resulting in high productivity.

[0050] Furthermore, the support section 2 includes a plurality of suction parts 21 that generate suction force and a connecting section 22 that connects the plurality of suction parts 21. The insertion section 221 is located in the center of the connecting section 22, that is, in the middle of the plurality of suction parts 21. As a result, the adhesive application jig 1 can stand stably on any position on the supported surface 51 of the object 5. In addition, since the adhesive application jig 1 is configured such that a pressing force P is generated in the center of the plurality of suction parts 21 that bear the reaction force F, it can stand stably on its own even when pressing the object 6 to be applied to. Therefore, the adhesive application jig 1 can further improve the quality of application.

[0051] Furthermore, the adhesive application jig 1 is provided with rotary joints 222 at both ends of the connecting portion 22. The rotary joints 222 are joints that are rotatable along the circumferential direction with the width direction X as the axis of rotation, and connect the suction portion 21 and the connecting portion 22 so as to be rotatable along the circumferential direction with the width direction X as the axis of rotation. As a result, the adhesive application jig 1 can exert its suction force without being affected by unevenness (manufacturing errors) of the supported surface 51 of the object 5, and can stand upright stably. Therefore, the adhesive application jig 1 can more effectively improve the quality of application.

[0052] Furthermore, the adhesive application jig 1 is equipped with a rotatable, freely adjustable contact portion 32 at the lower Z2 end of the shaft portion 31, which contacts the contact surface 61 of the workpiece 6. As a result, the adhesive application jig 1 can make contact even when the pressing surface 321 is not directly facing the pressing direction Z, by rotating the freely adjustable contact portion 32, and can generate a pressing force P. Therefore, the adhesive application jig 1 offers even better workability.

[0053] Furthermore, the adhesive application jig 1 allows for the application of the workpiece 6 to the application section 52 by a simple adhesive application method that includes a contact step S1 in which the pressing part 3 is brought into contact with the workpiece 6 placed on the application section 52, a placement step S2 in which the suction part 21 is placed on the workpiece 6, a pressing step in which the pressing part 3 is pressed toward the workpiece 6, and an injection step in which adhesive is injected into the filling space 65 formed between the workpiece 6 and the application section 52. Therefore, the adhesive application jig 1 can provide an adhesive application method that has better workability and application quality compared to conventional application methods.

[0054] [Examples] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to the following examples. The examples will be described with reference to Figure 9. Figure 9 is a diagram showing the relationship between the load and compressibility of the elastic ring 64 when the workpiece 6 is pressed.

[0055] The suction cup 211 of the adhesive application jig 1 should preferably be selected according to the characteristics (material) and dimensions of the elastic ring 64 used when injecting the adhesive. Therefore, the characteristics (material) and dimensions of the suction cup 211 are selected based on the results of a compression test as illustrated in Figure 9.

[0056] For example, if the diameter of the opposing surface 62 of the object to be treated 6 is 32 mm, the elastic ring 64 is an O-ring made of fluororubber (hardness 70 degrees), with a wire diameter of 2.0 mm and an inner diameter of 31.5 mm. When the adhesive application jig 1 supports the object to be treated 6, the elastic ring 64 receives a pressing force P and is compressed by approximately 25% in the pressing direction Z (see horizontal axis in Figure 9). At this time, the adhesive application jig 1 generates a load (pressing force P) of approximately 200 N (see vertical axis in Figure 9).

[0057] Therefore, the multiple suction cups 211 of the adhesive application jig 1 have a total suction force of 200 N (or more), which can suppress displacement and detachment caused by the reaction force F. For example, as illustrated in the embodiment, if there are two suction cups 211, the required suction force per suction cup 211 is 100 N.

[0058] Assuming operation using the adhesive application method exemplified in the embodiment, it is necessary to maintain the suction force for a predetermined time from when the adhesive is injected until it hardens, so a safety factor is set for the suction force of the multiple suction cups 211. If the safety factor is set to 2 and there are two suction cups 211, the required suction force per suction cup 211 will be 200N. Similarly, if the safety factor is set to 2 and there are three suction cups 211, the required suction force per suction cup 211 will be 134N.

[0059] Furthermore, even if the characteristics (material) and dimensions of the elastic ring 64 differ, the optimal configuration of the suction cup 211 can be selected by appropriately performing the compression test described above.

[0060] The above examples demonstrate that the adhesive application jig 1 according to the present invention allows for setting the optimal suction force and pressing force P according to the application conditions.

[0061] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and design modifications and the like are also included within the scope of the gist of the present invention. Furthermore, the components shown in the above embodiments can be combined as appropriate.

[0062] The Sustainable Development Goals (SDGs) are 17 international goals adopted at the UN Summit in September 2015. The adhesive application jig 1 according to this embodiment can contribute to achieving some of the 17 SDGs, such as goal 9, "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation."
