Description

  The present invention relates to an adhesive joint member in which the first and second adherend members are joined to each other by a chain-curing adhesive at the adherend joint portions respectively extended to the two adherend members, and the manufacture of the member It belongs to the technical field related to methods.

Conventionally, for example, as shown in Patent Document 1, when light or heat energy is applied, the energy application part undergoes a curing reaction to generate a curing reaction heat, and the curing reaction part is generated by the curing reaction heat. A chain-curing polymer that undergoes a chain-curing reaction by causing a curing reaction of a portion adjacent to the surface to generate a curing reaction heat is known. This chain-cured polymer contains, for example, an epoxy resin, a light / thermosetting initiator such as an aromatic sulfonium salt, and a thermosetting initiator such as a sulfonium salt. By continuously generating heat, the resin is subjected to a chain curing reaction. Patent Document 1 shows that the chain-cured polymer can be used as an adhesive.
JP-A-11-193322

  By the way, it is conceivable to use the chain-curing polymer as an adhesive so that the first and second adherends constituting the vehicle body of the vehicle are adhesively bonded to each other. That is, the first and second adherend members are each provided with an adhesion joining portion such as a flange portion, and a chain-curing polymer as an adhesive is provided between the adhesion joining portions of the two adherend members. A chain curing adhesive is disposed, light or heat energy is applied to a part of the chain curing adhesive, and the chain curing adhesive is subjected to a chain curing reaction, whereby the entire chain curing adhesive is cured. In this way, the time from the application of energy to the curing of the entire chain-curing adhesive can be shortened to about several tens of seconds and the bonding process can be shortened. It is not necessary to heat, and the equipment for joining can be simplified. In addition, by continuously joining the two adherent members, the rigidity of the adhesive joining member in which the two adherent members are joined to each other can be improved as compared to the case of spot joining. Accordingly, the vehicle body member can be thinned to reduce the weight.

  However, when the first and second adherends are bonded to each other by the chain-curing adhesive as described above, the chain-curing adhesive is applied to at least one of the adhering joints of the both adherends, so Assuming that there is a break in a portion of the chain-curing adhesive in the extending direction of the bonded joint when the bonded joints of the adhesive members are combined, the chain curing reaction stops halfway at the cut. The problem arises that the entire chain-curing adhesive cannot be cured. In particular, when the gap between the bonded joints is small, the amount of chain-cured adhesive between the bonded joints is small, so that there is a break in a part of the chain-cured adhesive in the extending direction of the bonded joints. As a result, the chain curing reaction is likely to stop halfway. When the chain curing reaction stops in the middle as described above, an unbonded portion is generated, and a desired adhesive strength cannot be obtained.

  The present invention has been made in view of such points, and the object of the present invention is to use the chain-curing adhesive when the first and second adherends are joined to each other by the chain-curing adhesive. It is to ensure that the entire chain curing adhesive is cured by preventing the chain curing reaction from stopping midway.

  In order to achieve the above object, according to the present invention, a standing portion projecting toward the second adherend member is provided on the side portion of the adherend joint portion of the first adherent member so as to extend the adherend joint portion. The gap between the adherend joint portions of the two adherend members is formed by contacting the above-mentioned standing portion on the side portion of the adherend joint portion of the second adherend member. The abutting part to be defined is continuously formed along the extending direction of the adherend joining part.

  Specifically, in the first aspect of the invention, the first and second adherends are bonded to each other by an adhesive at the bonded joints extending from the two adherends. Target members.

  When the energy is applied to a part of the adhesive, the adhesive is subjected to a curing reaction to generate a curing reaction heat, and a part adjacent to the curing reaction part by the curing reaction heat. Is a chain curing adhesive that undergoes a chain curing reaction by generating a curing reaction heat by curing reaction, and is cured by the application of the energy, The chain-curing adhesive is continuously provided along the extending direction of the adherend joining portion, and on the side of the adherend joining portion of the first adherent member, on the second adherend member side. Protruding standing portions are continuously formed along the extending direction of the adherend joining portion, and both sides are brought into contact with the standing portions on the side portions of the adherend joining portion of the second adherend member. The contact part that defines the amount of clearance between the adherend joint parts of the adherend member extends the adherend joint part. It assumed to be formed continuously along the direction.

  With the above-described configuration, a predetermined distance is set between the adherend joining portions of the two adherend members by the abutment between the standing portion formed on the first adherend member and the abutment portion formed on the second adherend member. Thus, it is possible to prevent the gap amount from becoming too small and causing a break in a part of the chain-curing adhesive in the extending direction of the adherend joined portion. In addition, the flow direction of the chain-curing adhesive is limited by the standing portion, and it is possible to effectively prevent the chain-curing adhesive from being cut. That is, before joining the adherend joint portions of the two adherend members, a chain-curing adhesive is usually extended to the adherend joint portion of at least one of the two adherend members. Arrange (apply) along the direction. And, when aligning the adherend joint portions of both adherend members, the chain curing adhesive tends to flow to the side of the adherend joint portion (the direction perpendicular to the adherend joint extension direction), The flow direction is changed by the standing portion to the extending direction of the adherend joining portion. As a result, when the chain-curing adhesive is disposed, even if a cut is generated in a part of the chain-bonding adhesive extension direction of the chain-curing adhesive, the change in the flow direction causes the extension of the bond-bonding part extension. When the direction both side parts approach each other and are connected and the alignment of the adherend bonded parts is completed, there is no break. Therefore, the chain curing reaction of the chain curing adhesive is reliably performed without stopping in the middle, and the entire chain curing adhesive can be reliably cured.

  According to a second aspect of the present invention, in the first aspect of the present invention, the upright portions are respectively formed on both side portions of the adherend joining portion of the first adherent member, and the abutting portion is the first contact portion. Formed on both side portions of the adherend joint portion of the two adherend members, and the two abutment portions abut on the compatible portion portion, so that between the adherend joint portions of the two adherend members. It is assumed that a space for filling the chain-curing adhesive is defined.

  As a result, a predetermined gap amount can be reliably ensured between the adherend joint portions of both adherend members, and the standing portions are formed on both sides of the adherend joint portions, so that chain hardening adhesion is achieved. It can prevent more reliably that a cut | interruption arises in a part of the adhesion joining part extension direction of an agent.

  According to a third aspect of the present invention, in the first or second aspect of the invention, each of the adherend members has a flange portion that is overlapped with each other by joining the two adherend members. Assume that the joint portions are respectively provided on the mating surfaces of the flange portions of the two adherend members so as to extend along the length direction of the flange portions.

  As a result, it is possible to form the standing portion and the abutting portion on the flange portion. As a result, the standing portion and the abutting portion can be easily formed without affecting the shapes of the main body portions of the two adherend members. Can be formed.

  According to a fourth aspect of the present invention, there is provided a method for producing an adhesive bonding member in which the first and second adherent members are joined to each other by an adhesive at the adherend joining portions respectively extended from the adherend members.

In the state where the adherend joint portions of the two adherend members are aligned with the side portions of the adherend joint portions, the standing portion projecting toward the second adherend member is in the direction in which the adherend joint portions extend. The second adherend member is erected in the adherend joint portion alignment step at a side portion of the adherend joint portion of the second adherend member. Suppose that the contact part which prescribes | regulates the gap | clearance amount between the adhesion joining parts of both adherend members by contact | abutting to a part is formed continuously along the adhesion joining part extension direction.

  According to the present invention, the contact portion of the second adherent member abuts the standing portion of the first adherent member in the adherend joint portion matching step, so that the adherend joint portions of the two adherent members are in contact. A predetermined gap amount is ensured. In addition, even if there is a break in a part of the chain-bonding adhesive extension direction in the adhesive placement step, the adherence bonding part is used when aligning the adhesion bonding parts of the two adhesion members. The flow direction of the chain-curing adhesive that tends to flow to the sides of the adhesive is changed by the standing portion to the extending direction of the adherend bonded portion, and when the adherend bonded portion alignment step is completed, there is no break. Thereafter, the chain curing adhesive undergoes a chain curing reaction by applying light or heat energy to a predetermined portion of the chain curing adhesive. At this time, since there is no cut in a part of the direction of extension of the bonded joint of the chain-curing adhesive, the chain-curing reaction of the chain-curing adhesive is reliably performed without stopping in the middle, and the entire chain-curing adhesive Can be reliably cured.

  In the invention of claim 5, in the invention of claim 4, in the adhesive placement step, the chain-curing adhesive is adhered and bonded to an adhesion joining portion of only one of the adherend members. It is assumed that it is a step of arranging along the part extending direction.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an adhesive bonding member 1 according to an embodiment of the present invention. In this adhesive bonding member 1, the first and second adherend members 2 and 3 are bonded to each other by an adhesive (a chain curing adhesive described later). It is formed by joining. In the present embodiment, the first adherent member 2 is a metal vehicle body outer panel made of steel or aluminum, and the second adherend member 3 is a metal vehicle body inner panel made of steel or aluminum, The adhesive joining member 1 formed by joining both the adherend members 2 and 3 constitutes a part of a vehicle body of a vehicle (automobile or the like), and is continuous in the length direction of the adherend members 2 and 3. And has a closed cross-sectional portion 4 extending in the direction. Note that at least one of the adherend members 2 and 3 may be made of resin.

  The first adherent member 2 includes a main body 2a extending along the closed cross section 4 and forming a half of the periphery of the closed cross section 4; and the main body 2a on both sides in the width direction of the main body 2a. The second adherend member 3 extends along the closed cross-section portion 4 and the closed cross-section portion 4.

Then, the flange portion 2b of the first adherend member 2 and the flange portion 3b of the second adherend member 3 are overlapped with each other (the left flange portions 2b and 3b are overlapped with each other and the right flange portion is overlapped). 2b and 3b are superposed on each other), and an adhesive (chain curing adhesive 8 to be described later) disposed between the mating surfaces of the two flange portions 2b and 3b is used to make the first at both flange portions 2b and 3b. The second adherend members 2 and 3 are joined to each other. Since the left and right flange portions 2b and 2b have the same configuration, and the left and right flange portions 3b and 3b have the same configuration, one flange portion 2b and a flange overlapped with the flange portion 2b will be described below. The part 3b will be described.

  In the above adhesive, when light (ultraviolet light or the like) or heat energy is applied to a part of the adhesive, the energy applying portion undergoes a curing reaction to generate a curing reaction heat, and the curing reaction heat causes the curing reaction. A chain-curing adhesive that undergoes a chain-curing reaction when a part adjacent to the part undergoes a curing reaction to generate a curing reaction heat, and is cured by applying the energy. This chain-curing adhesive contains an epoxy resin and a curing initiator. The curing initiator includes a light / thermosetting initiator such as an aromatic sulfonium salt and a thermosetting initiator such as a sulfonium salt. Then, by applying the above-mentioned energy to a predetermined portion of the adhesive, the adhesive is chain-cured by generating a cation and a curing reaction heat inside the adhesive, thereby curing the entire adhesive. Let

  Examples of the epoxy resin include an alicyclic epoxy resin and a bisphenol A type epoxy resin. With the alicyclic epoxy resin, a curing reaction (cationic polymerization) can be favorably performed. In the bisphenol A type epoxy resin, High adhesive strength can be obtained. Since the bisphenol A type epoxy resin has a hydroxyl group and a benzene ring that have good adhesion to the metal, particularly high adhesion strength is obtained when both the adherend members 2 and 3 are made of metal as in this embodiment. .

  As shown in FIG. 2, the width direction of the mating surface of the flange portion 2b in this embodiment is a part of the width direction (left-right direction in FIG. 2) of the mating surface of the flange portion 2b in the first adherend member 2 In the portion excluding both ends, the adherend joining portion 6 of the first adherend member 2 is continuously extended along the length direction of the flange portion 2b (the direction perpendicular to the paper surface of FIG. 2). Yes. Further, the second adherend member 3 has a second portion in the width direction of the mating surface of the flange portion 3b (in this embodiment, the portion excluding both end portions in the width direction of the mating surface of the flange portion 3b). The adherend joining portion 7 of the adherend member 3 is continuously extended along the length direction of the flange portion 3b.

  Between the adherend joining portions 6 and 7 of the two adherend members 2 and 3, the chain curing adhesive 8 is continuously provided along the extending direction of the adherend joining portions. In the present embodiment, the adherend joining parts 6 and 7 and the chain curing adhesive 8 are provided over the entire length direction of the flange parts 2b and 3b.

  The flange portion 2b of the first adherend member 2 protrudes toward the second adherend member 3 at both side portions of the adherend joint portion 6 (near both ends in the width direction of the mating surface of the flange portion 2b). The standing portions 12, 12 are integrally formed. The standing portion 12 extends continuously in the flange portion 2b along the extending direction of the adherend joining portion over the entire length direction of the flange portion 2b. It is composed of an inclined surface on the opposite side and has a triangular cross section. In the present embodiment, since the thickness of the first adherend member 2 is small, a cross-sectional V-shaped groove portion that is recessed corresponding to the standing portion 12 is formed on the side surface opposite to the mating surface of the flange portion 2b. It will be formed.

  On the other hand, on both side portions of the flange joint portion 7 of the flange portion 3b of the second adherend member 3 (in the vicinity of both ends in the width direction of the mating surface of the flange portion 3b), Abutting portions 13 and 13 for defining a gap amount between the adherend joining portions 6 and 7 of the two adherend members 2 and 3 are integrally formed by being brought into contact with the protruding tip portions, respectively. The contact portion 13 extends continuously in the flange portion 3b along the extending direction of the adherend joint portion over the entire length direction of the flange portion 3b. It is formed of an inclined surface on the opposite side and is formed in a V-shaped cross section. In the present embodiment, since the plate thickness of the second adherend member 3 is small, a bead having a triangular cross section protruding corresponding to the contact portion 13 is formed on the side surface opposite to the mating surface of the flange portion 3b. It will be formed.

  When both the abutting portions 13 and 13 abut on the compatible portions 12 and 12, respectively, a space for filling the chain-curing adhesive 8 is defined between the adherend joining portions 6 and 7, and the adherend portion is adhered. The gap amount between the joint portions 6 and 7 (that is, the thickness of the chain-curing adhesive 8) is set to a predetermined value (preferably 0.01 mm or more and 10 mm or less). In addition, it is preferable that the width | variety of the adhesion joining part 6 (or adhesion joining part 7) is 1 mm or more and 30 mm or less. Moreover, although it is preferable that the cross-sectional shape of the said filling space is constant over the whole length direction of the flange part 2b (3b), the said gap | interval amount and the adhesion joining part 6 (or adhesion joining part 7) are the same. At least one of the widths may be different depending on the position in the length direction of the flange portion 2b (3b).

  At the intermediate portion in the length direction of the flange portion 3 b of the second adherend member 3, there is an adherend joint portion 7 and an opening 11 (see FIG. 1) that opens to the side surface opposite to the adherend joint portion 7. The chain-cured adhesive 8 is formed by applying the energy to the chain-cured adhesive 8 through the opening 11 as will be described later.

  Next, a method for manufacturing the adhesive bonding member 1 will be described with reference to FIG.

  First, the first and second adherend members 2 and 3 having the flange portions 2b and 3b, the standing portion 12, the contact portion 13 and the like as described above are prepared, as shown in FIG. The first adherend member 2 is set on the support base 15. At this time, the mating surface of the flange portion 2b of the first adherend member 2 faces upward, and the side surface opposite to the mating surface is on the upper surface of the support portion 15b protruding upward from the base portion 15a of the support base 15. It is in contact.

  The chain-curing adhesive 8 is extended to a part of the width direction of the bonded joint 6 (preferably the center in the width direction) on the mating surface of the flange portion 2b of the first adhered member 2. Apply continuously along the installation direction. This application is performed, for example, by continuously discharging adhesive from a nozzle configured to move along the length of the flange portion 2b at a constant speed by a robot, and the chain-curing adhesive 8 is applied to the flange portion 2b. Apply over the entire length. The maximum height of the applied chain curing adhesive 8 is larger than the predetermined value. At this stage, even if there is a break in a part in the extending direction of the adherence / bonding portion of the chain-curing adhesive 8, when the mating surfaces of the flange portions 2 b and 3 b are aligned with each other as described later, It becomes a state connected to.

  Subsequently, as shown in FIG. 3 (b), the mating surfaces of the flange portions 2b and 3b in the first and second adherend members 2 and 3 are matched with each other (the adherend joint portions 6 and 7). The flange portions 2 b and 3 b are clamped by the clamp member 16 a of the clamp means 16. That is, the flange portions 2b and 3b are pressed against the support portion 15b by the clamp member 16a. At this time, the clamp member 16a is pressed against the protruding tip of the bead in the flange portion 3b. Even if pressed in this way, the rigidity of the flange portion 3b is increased by the bead, so that the flange portion 3b does not bend and between the adherend joint portions 6 and 7 over the entire extending direction of the adherend joint portion. Can be maintained at the predetermined value. Note that the clamp member 16a does not cover the opening 11 by pressing a position different from the opening 11 in the length direction of the flange portion 3b.

  When aligning the mating surfaces of the flange portions 2b and 3b, the chain-curing adhesive 8 is pressed against the adherend joining portion 7, so that both side sides of the adherend joining portion 6 (extending the adherend joining portion are extended). In a direction perpendicular to the direction) and eventually comes into contact with the standing portion 12. For this reason, the flow direction of the chain-curing adhesive 8 is changed by the standing portion 12 in the direction in which the adherend bonded portion extends. Therefore, even when a cut is generated in a part of the chain bonding adhesive 8 extending direction of the chain hardening adhesive 8 when the chain hardening adhesive 8 is applied, the change in the flow direction is caused by the change of the flow direction. When the both sides of the installation direction are close to each other and connected to each other and the alignment of the mating surfaces of the flange portions 2b and 3b (the alignment of the adherend joining portions 6 and 7) is completed, there is no break. Further, when the matching of the mating surfaces of the flange portions 2b and 3b is completed, the both abutting portions 13 and 13 come into contact with the compatible portions 12 and 12, respectively. A space for filling the chain-curing adhesive 8 is defined, and the gap amount between the adherend joining parts 6 and 7 is set to the predetermined value. It is possible to prevent a break from occurring in a part of the adhesion joining portion extending direction. Moreover, since the thickness of the chain-curing adhesive 8 is defined to be a predetermined value (a gap amount between the adherend joining portions 6 and 7), the adhesive strength can be reliably ensured. When the mating surfaces of the flange portions 2b and 3b are matched, it is preferable to close the opening 11 with a closing member.

  Instead of applying the chain-curing adhesive 8 to the mating surface of the flange portion 2b of the first adherend member 2 before mating the mating surfaces of the flange portions 2b and 3b, the second adherend member 3 You may make it apply | coat continuously to a part (width direction center part of the width direction center) of the adherend joining part 7 in the mating surface of the flange part 3b along the extending direction of the adherend joining part. In this case, the second adherend member 3 is set on the support base 15 so that the mating surface of the flange portion 3b faces upward, and the chain curing adhesive 8 is applied to a part of the adherend joint portion 7 in the width direction. (It is preferable to provide the opening part 11 in the flange part 2b of the 1st to-be-adhered member 2 instead of providing in the flange part 3b.). Thereafter, the contact surfaces of the flange portions 2b and 3b are brought into contact with each other so that the contact portions 13 and 13 are brought into contact with the compatible portions 12 and 12, respectively. Also in this case, when matching the mating surfaces of the flange portions 2b and 3b, the flow direction of the chain-curing adhesive 8 is changed by the standing portion 12 to the extending direction of the adherend joining portion, and the flange portions 2b and 3b When the alignment of the mating surfaces is completed, there is no break. However, it is preferable to apply the chain-curing adhesive 8 to the mating surface of the flange portion 2b of the first adherend 2. That is, in this case, when the chain curing adhesive 8 is disposed at an accurate position with respect to the standing portion 12 and the mating surfaces of the flange portions 2b and 3b are aligned, the flow direction of the chain curing adhesive 8 is increased. It is possible to reliably change the extending direction of the adherend joint portion by the setting portion 12, and to prevent the chain-curing adhesive 8 from leaking from the adherend bonding portion 6 to the outside by the standing portion 12. Can be sure.

  Alternatively, the chain curing adhesive 8 may be applied to the mating surfaces of the flange portions 2b and 3b of the two adherend members 2 and 3, respectively. However, from the viewpoint of simplifying the adhesive placement process, it is preferable to apply the chain-curing adhesive 8 to only one of the flange portions 2b and 3b.

  Next, as shown in FIG. 3 (c), light or heat energy is applied to the predetermined part (the part corresponding to the opening part 11) of the chain-curing adhesive 8 through the opening part 11. The cured adhesive 8 is subjected to a chain curing reaction. At this time, as described above, since there is no break in a portion of the chain-bonding adhesive 8 extending direction of the chain-curing adhesive 8, the chain-curing reaction of the chain-curing adhesive 8 is reliably performed without stopping in the middle, The entire chain curing adhesive 8 is cured.

  Note that the opening 11 for applying energy to the chain-curing adhesive 8 does not need to be provided at one location for one flange portion 3b, but is provided at a plurality of locations (covered by the clamp member 16a) in the extending direction of the adherend joining portion. Energy may be applied to the chain-curing adhesive 8 from each opening 11.

  Here, the specific example of the vehicle body as the said adhesive joining member 1 is shown. FIG. 4 shows a side body 21 of the vehicle body, and the side body 21 includes an outer panel 22 and an inner panel 23 as shown in FIG. On the entire periphery of the peripheral edge of the door opening 24 of the side body 21, the flange 22 a of the outer panel 22 (contact portions 13, 13 are formed) and the flange 23 a of the inner panel 23 (upright portion 12, 12 are formed and bonded to each other. The outer panel 22 corresponds to the second adherent member 3, the inner panel 23 corresponds to the first adherent member 2, and the configuration of the joint portion of the flange portions 22 a and 23 a is configured by both adherent members 2, 2. 3 is the same as the joint portion 3.

  FIG. 6 shows a joint portion between the roof panel 26 and the roof side rail 27. That is, the flange portion 28a (the standing portions 12 and 12 are formed) of the inner panel 28 of the roof side rail 27 and the flange portion 29a (the contact portions 13 and 13) of the outer panel 29 of the roof side rail 27 are formed. And the flange portion 26a of the roof panel 26 (the contact portions 13 and 13 are formed) and the flange portion 29a of the outer panel 29 of the roof side rail 27 (the contact portion 13). , 13 are adhesively bonded to each other. In the joining of the inner panel 28 and the outer panel 29 of the roof side rail 27, the inner panel 28 corresponds to the first adherend member 2, the outer panel 29 corresponds to the second adherent member 3, and the joining portion. This configuration is the same as the joint portion of the two adherend members 2 and 3. Further, in joining the roof panel 26 and the outer panel 29 of the roof side rail 27, the outer panel 29 of the roof side rail 27 corresponds to the first adherend member 2, and the roof panel 26 is the second adherend member 3. The structure of the joint portion is the same as that of the joint portions of the two adherend members 2 and 3.

  FIG. 7 shows a modification of the joint portion between the roof panel 26 and the roof side rail 27. That is, in this modified example, only the shape of the flange portion 26a of the roof panel 26 is different from that of FIG. 6, and the abutting portion 13 of the flange portion 26a is not V-shaped in cross section and is inclined. It has a flat shape with no surface. In this case, since the bead does not appear in the appearance, the appearance can be improved.

  FIG. 8 shows a joint portion between the side sill 31 and the floor panel 32.
