Description

  The present invention relates to a method for applying a sealant to a gap at a joint between two workpieces and a sealant shaping device used therefor.

  Conventionally, an outer side panel of an automobile is manufactured by press-forming a single steel plate and punching an opening. However, the outer side panel has a large opening in the part corresponding to the front door and the rear door, and the steel plate punched out to form this opening often becomes scrap, so a decrease in yield can be avoided. There is no problem.

  In order to solve the above problem, it is conceivable to divide the side panel outer into two parts. In this case, for example, the side panel outer is divided at the lower end portion of the front pillar, the upper portion of the center pillar, and the lower end portion of the rear pillar. In this way, the outer side panel is divided into a front pillar, an upper part of the center pillar upper part, an upper work composed of a rear pillar and a quarter panel, and a lower work composed of a center pillar lower part and a rocker panel.

  Therefore, for example, in the case of the upper work, the convex part (rear pillar and quarter panel) of one upper work is the concave part of the other upper work (corresponding to the space between the center pillar and the rear pillar, the front door and the rear door). So that it fits in As a result, a large opening corresponding to the front door and the rear door can be effectively used, and the yield can be improved by eliminating waste of the steel plate.

  By the way, when the side panel outer is divided into two parts, an upper work and a lower work, a gap is formed at the joint where the two works are joined. Therefore, it is necessary to apply a sealant to this gap. As a method for applying the sealing agent, for example, a method is known in which a robot hand holds a sealer gun and discharges the sealing agent along a gap formed at the joint from the sealer gun (for example, Patent Document 1). reference).

Japanese Utility Model Publication No. 7-31166

  However, simply discharging the sealant from the sealer gun along the gap formed in the joint will result in uneven shapes of each part of the applied sealant, which is sufficient when the joint is visible from the outside. There is a disadvantage that appearance quality cannot be obtained.

  The present invention provides a sealing agent application method and a sealing agent shaping device used therefor, which can solve such inconvenience and obtain an excellent appearance quality when applying a sealing agent to a gap at a joint portion between two workpieces. The purpose is to do.

  In order to achieve this object, the sealing agent application method of the present invention is a method of applying a sealing agent having fluidity to a gap at a joint portion between two workpieces, and an application step of applying the sealing agent to the gap. A shaping step for adjusting the shape of the applied sealing agent, the shaping step comprising: a groove-like non-contact portion along the length direction of the joint portion; and the non-contact portion on both sides of the non-contact portion. A shaping mold member comprising a pair of contact portions having contact surfaces facing in the same direction, the contact surfaces of the pair of contact portions being in contact with the surface of the joint portion on both sides of the applied sealant; An arrangement step in which the sealing agent is accommodated in the non-contact portion, and after the arrangement step, the shaping member is pressed against the joint portion, and the non-contact portion is deformed by the pressing. Immersing the sealant in the length direction by the non-contact portion. It allows, while preventing leaching of the contacts of the pair in the width direction of the sealant, characterized in that it comprises a step of shaping the sealant along the contour of the non-contact portion.

  In the sealing agent application method of the present invention, first, a sealing agent having fluidity is applied to the gap at the joint between two workpieces. Next, a shaping member is disposed at the joint. In the shaping mold member, a pair of contact portions extending along the length direction of the joint portion is in contact with the joint portion on both sides of the applied sealant, and between the pair of contact portions. A sealant is accommodated in the non-contact portion.

  Next, when the shaping mold member is pressed against the joint, and the sealant accommodated in the non-contact part is pressed toward the joint, the sealant is easily deformed because it has fluidity. . At this time, the sealing agent is prevented by the contact portion from protruding in the width direction of the joint portion, but the non-contact portion permits the protrusion of the joint portion in the length direction. The agent is pushed out in the length direction of the joint.

  As a result, in the sealing agent application method of the present invention, the sealing agent applied to the gap is shaped along the shape of the non-contact portion, and an excellent appearance shape can be obtained at the joint portion.

  On the other hand, the sealing agent shaping device of the present invention is a shaping device that adjusts the shape of a sealing agent having fluidity applied to the gap at the joint between two workpieces, and extends along the length direction of the joint. A pair of contact portions that contact the joints on both sides of the applied sealant to prevent the sealant from extruding in the width direction, and a portion sandwiched between the pair of contact portions. A shaping mold member including a non-contact portion that accommodates the sealing agent applied to extend along the length direction of the joint portion and allows the sealing agent to erode in the length direction; A pressing member that presses the shaping mold member against the joint portion, and the pair of contact portions are oriented in the same direction as the non-contact portion on both sides of the non-contact portion and are in contact with the joint portion. A contact surface for contacting the surface of the joint portion to prevent leaching of the sealant; Characterized in that it is constituted by a member which is deformed by pressing by the pressing member.

  According to the sealing agent shaping device of the present invention, a pair of contact portions extending along the length direction of the joint portion on both sides of the sealant having fluidity applied to the gap between the joint portions of the two workpieces. The sealant is accommodated in the non-contact portion between the pair of contact portions. Then, by pressing the shaping mold member against the joint with the pressing member, the sealing agent is easily deformed because it has fluidity.

  At this time, the sealing agent is prevented by the contact portion from protruding in the width direction of the joint portion, but the non-contact portion permits the protrusion of the joint portion in the length direction. The agent is pushed out in the length direction of the joint. As a result, in the sealing agent shaping device of the present invention, the sealing agent applied to the gap is shaped along the shape of the non-contact portion, and excellent appearance quality can be obtained at the joint.

  In the sealing agent shaping device of the present invention, the shaping mold member is provided on a side opposite to the joining portion of the non-contact portion, is pressed against the joining portion side, and is accommodated in the non-contact portion. Preferably, the pressing member includes a pressing member that is pressed against the pressing portion and deforms the sealant by the pressing portion.

  However, in this case, the pressing portion is provided on the opposite side of the non-contact portion from the joint portion, and is sandwiched between the pair of contact portions. For this reason, when the pressure contact member is pressed against the pressing portion and the sealing agent is pressed to the joint portion side by the pressing portion, the pair of contact portions falls to the pressing portion side, and the sealing agent in the width direction of the joint portion There is a concern that the invasion cannot be sufficiently prevented.

  Therefore, in the sealing agent shaping device of the present invention, it is preferable that the thickness d1 of the portion adjacent to the contact portion of the pressing portion is smaller than the thickness d2 of the portion adjacent to the pressing portion of the contact portion. By making the pressing part thinner than the contact part, the pressing part is more easily deformed than the contact part, and the contact part is less likely to fall down on the pressing part side. Extrusion can be reliably prevented.

  Moreover, the sealing agent shaping apparatus of this invention WHEREIN: It is preferable that the said press-contact member is provided with the limit pin which regulates the press-contact amount with respect to the said press part. Since the pressure contact member is provided with a limit pin, the amount of pressure contact with the pressing portion is restricted and the pressure contact member is not excessively pressed, so that the thickness of the shaped sealing agent can be made uniform.

  In the sealing agent shaping device of the present invention, the contact portion includes a plurality of grounding portions that extend along the length direction of the joint portion and are grounded to the joint portion, and the grounding portions are predetermined to each other. It is preferable that the air gap is provided.

  The contact portion is provided with a plurality of grounding portions that are grounded to the joint portion with a predetermined gap therebetween, so that the grounding area with respect to the joint portion is smaller than when a single grounding portion is provided, The contact pressure increases when pressed with the same pressure. As a result, when the pressure contact member is pressed against the pressing portion, the pair of contact portions can be further prevented from falling to the pressing portion side.

  Moreover, the sealing agent shaping apparatus of this invention WHEREIN: It is preferable that the said contact part is equipped with the air vent hole which prevents passage of a sealing agent and accept | permits passage of air.

  When the contact portion is provided with an air vent hole, only the air in the non-contact portion can escape from the air vent hole to the outside when the pressure contact member is pressed against the pressing portion to shape the sealant. It can prevent that a defect | deletion arises on the surface of the made sealing agent.

  Further, in the sealing agent shaping device of the present invention, the portions adjacent to the contact portions on both sides of the non-contact portion are configured by inner walls having a predetermined height with respect to the contact surface of the contact portion with respect to the workpiece. It is preferable.

  According to this, at the time of shaping the sealing agent, side surfaces having a certain height are formed on both sides of the sealing agent as portions corresponding to the inner walls on both sides of the non-contact portion. For this reason, both sides of the sealant have a thickness corresponding to this side surface, and the boundary of the sealant to the workpiece is clearly defined by the side surface of the sealant. Therefore, the sealing agent can be shaped as a uniform material without any disturbance.

  Further, in the sealing agent shaping device of the present invention, the shaping mold member is disposed at a position separated from the contact surface by a predetermined distance not more than the height of the inner wall when the shaping mold member is deformed. It is preferable that a rigid body is embedded to prevent the thickness from being below a predetermined value.

  According to this, since the height of the inner wall on both sides of the non-contact portion does not become a predetermined value or less due to the embedded rigid body, the height of the side surface formed on both sides of the sealant corresponding to this inner wall Is less than a predetermined value, the boundary between the workpiece and the sealing agent can be surely defined and uniform without disturbance.

  That is, since the shaped sealing agent has a side surface corresponding to the inner wall of the non-contact portion, the boundary with respect to the workpiece is clearly defined and uniform without any disturbance.

  Next, embodiments of the present invention will be described with reference to the accompanying drawings.

  The sealing agent application method of this embodiment is applied when applying a sealing agent 5 having fluidity to the gap 4 in the joint 3 between the two workpieces 1 and 2 as shown in FIGS. 1A and 1B.

  The workpieces 1 and 2 are provided with convex portions 1a and 2a at the center in the width direction, and the convex portions 1a and 2a extend in the length direction of the workpieces 1 and 2, respectively. As shown in FIG. 1B, the workpiece 1 is divided into a high stage side and a low stage side by a step part 1b, and the low stage side is an end part. The workpiece 2 is stacked on the lower end of the workpiece 1 to form a joint 3, and a gap 4 is formed between the end of the workpiece 2 and the step 1 b.

  In the sealing agent application method of the present embodiment, first, the sealing agent 5 is discharged to the joint portion 3 by, for example, a sealer gun (not shown) held by a robot hand or the like, and the gap 4 extends across the workpieces 1 and 2. Is applied to seal. Here, when the applied sealant 5 is simply discharged from the sealer gun, the shape of each part becomes uneven, and excellent appearance quality cannot be obtained.

  Therefore, in the sealing agent application method of the present embodiment, the applied sealing agent 5 is then shaped using the sealing agent shaping device 6 shown in FIGS. 2A and 2B. The sealing agent shaping device 6 includes a shaping mold member 7 and a pressure contact member 8 that constitutes a pressing member that presses the shaping member 7 against the joint portion 3.

  The shaping mold member 7 is made of a soft resin such as silicone resin, and has a bowl shape including a pair of side walls 9 and 9 and a groove 10 sandwiched between the side walls 9 and 9. The concave portion 11 having a shape along the two convex portions 1a and 2a is provided.

  The side walls 9, 9 extend along the length direction of the joint portion 3, and include inclined portions 9 a at the upper portions of both ends. The bottom surfaces of the side walls 9 and 9 are a pair of contact portions 12 and 12 that come into contact with the joint portion 3 on both sides of the applied sealant 5, and each contact portion 12 includes a pair of grounding portions 12 a and 12 a. 12a and a gap portion 12b formed between the grounding portions 12a and 12a.

  The groove portion 10 includes a bottom surface 13 that connects the side walls 9, 9 to the bottom portion, and the joint portion 3 side of the bottom surface 13 is a non-contact portion 14. The non-contact portion 14 has an arch shape in cross section and opens to the outside at the end of the shaping member 7 and accommodates the sealing agent 5 applied to the joint portion 3.

  The contact portion 12 includes an air vent hole 15 having one end communicating with the non-contact portion 14 and the other end opening to the outside. The air vent hole 15 is formed so as to prevent passage of the sealant 5 accommodated in the non-contact portion 14 while allowing passage of air.

  In the shaping mold member 7, the thickness d 1 of the bottom surface 13 is smaller than the thickness d 2 of the contact portion 12, and the bottom surface 13 is formed thinner than the contact portion 12.

  The press contact member 8 is made of, for example, a hard resin such as an acrylic resin, and includes split molds 8 a and 8 b each having a shape that follows the shape of the bottom surface 13 of the groove portion 10 of the shaping mold member 7. The split molds 8a and 8b are inserted into the groove portion 10 from the left and right of FIG. 2A and are pressed against the bottom surface 13, and press the sealing agent 5 using the bottom surface 13 as a pressing portion. Further, the split molds 8 a and 8 b are provided with a limit pin 16 that restricts the amount of press contact on the surface facing the bottom surface 13 when pressed against the bottom surface 13.

  Next, in the sealing agent application method of the present embodiment, as shown in FIG. 3A, the shaping mold member 7 is disposed in the joint portion 3. The shaping mold member 7 is pressed against the joint portion 3 by an actuator (not shown) or the like, and the contact portions 12 and 12 are disposed on both sides of the seal agent 5, while the non-contact portion 14 accommodates the seal agent 5. Done.

  At this time, since the bottom surface of the contact portion 12 of the shaping mold member 7 is divided into a pair of ground portions 12a and 12a, if the pressure of the actuator or the like is constant, the ground contact area is larger than when the bottom surface is not divided. The contact ground pressure can be increased.

  In addition, as shown in FIG. 4, the shaping mold member 7 includes a first piece 17 that is in contact with the upper surface of the side wall 9, and a second piece 18 that is in contact with the inclined portion 9 a and the first piece 17. Then, it is pressed to 3 at the joint. By doing in this way, it can adjust so that the shaping | molding die member 7 may press-contact with each part of the junction part 3 uniformly. The first piece 17 and the second piece 18 together with the pressure contact member 8 constitute a pressing member that presses the shaping mold member 7 against the joint portion 3.

  Next, as shown in FIG. 3B, the pressure contact member 8 is inserted into the groove portion 10 of the shaping mold member 7, and is pressed against the bottom surface 13 by an actuator (not shown). At this time, as shown by an arrow in FIG. 2A, first, the split molds 8 a and 8 b are pressed against the bottom surface 13 from the left and right of the shaping mold member 7, and then the split molds 8 a and 8 b are connected to the bottom surface 13 from above the shaping mold member 7. Press contact.

  In this case, the shaping mold member 7 is made of a soft resin such as silicone resin, and the bottom surface 13 is formed thinner than the contact portion 12, so that it is easily deformed and accommodated in the non-contact portion 14. The sealing agent 5 is pressed. On the other hand, since the contact portion 12 is thicker than the bottom surface 13 and the ground pressure is increased by the grounding portions 12a and 12a, the side wall 9 falls in the groove portion 10 direction even if the bottom surface 13 is deformed in the sealant 5 direction. There is nothing.

  Since the sealing agent 5 has fluidity, when pressed by the bottom surface 13, the sealing agent 5 is cast in the width direction and the length direction of the joint portion 3 along the shape of the non-contact portion 14. At this time, the sealing agent 5 is blocked by the contact portion 12 in the width direction of the joint portion 3 and does not invade the outside of the contact portion 12, but the opening of the non-contact portion 14 in the length direction of the joint portion 3. It can invade from the part to the outside.

  The sealant 5 that has erected outward may be cut off after solidifying, but a notch (not shown) that communicates with the opening of the non-contact part 14 is formed in the shaping mold member 7, You may make it accommodate in this notch part. By accommodating the sealing agent 5 in the notch, the step of cutting after solidification can be omitted.

  Further, when the sealing agent 5 is pressed by the bottom surface 13, the air present inside the non-contact part 14 is discharged to the outside from the air vent hole 15 provided in the contact part 12. Therefore, when the sealing agent 5 is solidified, it is possible to prevent a defective portion from being formed on the surface.

  Moreover, since the amount of pressure contact with the bottom face 13 is regulated by the limit pin 16, the pressure contact member 8 can shape the sealant 5 cast as described above to a uniform thickness.

  In the sealing agent application method of the present embodiment, for example, the sealing agent 5 made of an ultraviolet curable resin can be used. When the sealing agent 5 is made of an ultraviolet curable resin, it is preferable that the shaping mold member 7 is made of a silicone resin and the pressure contact member 8 is made of an acrylic resin. If it does in this way, since both a silicone resin and an acrylic resin permeate | transmit an ultraviolet-ray, it can irradiate an ultraviolet-ray through the shaping | molding type | mold member 7 and the press-contacting member 8. FIG. As a result, the pressure contact member 8 is pressed against the bottom surface 13 of the shaping mold member 7 and the sealing agent 5 can be solidified by irradiating the sealing material 5 with ultraviolet rays while the sealing material 5 is pressed by the bottom surface 13. is there.

  FIG. 5 is a cross-sectional view showing another example of a shaping mold member in the sealing agent shaping device 6. In FIG. 5, the cross section of one side of the non-contact part 20 in the shaping | molding die member 19 which concerns on this example is shown. The cross section on the other side of the non-contact portion 20 is the same as this.

  As shown in FIG. 5, the shaping mold member 19 includes a contact portion 21 similar to the contact portion 12 of the shaping mold member 7 described above. The part adjacent to the contact part 21 of the non-contact part 20 comprises the inner wall 20a. The inner wall 20a forms an angle θ with respect to the contact surface 21a of the contact portion 21 adjacent thereto with respect to the workpiece 1 or 2, and has a height h1 with respect to the contact surface 21a. As the angle θ, for example, an angle of 90 ° or the vicinity thereof is applicable. The height h1 corresponds to, for example, 0.1 [mm] or a value in the vicinity thereof.

  FIG. 6 is a perspective view showing a part of the sealing agent 5 shaped using the shaping mold member 19. As shown in FIG. 6, the shaped sealant 5 has a partially cylindrical curved surface 5b opposite to the workpiece 1 or 2, and side surfaces 5a on both sides thereof. The side surface 5a is shaped by the inner wall 20a whose height h1 is reduced by deformation of the shaping mold member 19 during shaping. Considering this amount of decrease, the height h1 of the inner wall 20a is set to ensure a height of, for example, 0.05 to 0.1 [mm] as the height h2 of the side surface 5a.

  The height h2 of the side surface 5a to be secured is determined in consideration of, for example, the water stop performance and appearance required for the shaped sealant 5 after shaping. The other configuration of the shaping mold member 19 is the same as that of the shaping member 7 in FIG. 2A.

  The shaping of the sealing agent 5 by the shaping mold member 19 is performed in the same manner as described above with reference to FIGS. At that time, as shown in FIG. 4, the shaping mold member 19 is pressed against the joint portion 3 via the first piece 17 and the second piece 18 abutted against the inclined portion 9 a and the first piece 17, and As shown in FIG. 3B, the pressure contact member 8 is pressed against the bottom surface 13 of the shaping mold member 19.

  At this time, the shaping die member 19 is deformed by the pressure contact with the joint portion 3, and the height of the inner wall 20a of the non-contact portion 20 is reduced from the original height h1. For example, if the height h1 is 0.1 [mm], the height is reduced to 0.05 [mm]. Further, due to the pressure contact with the bottom surface 13 of the pressure contact member 8, the sealant 5 flows in the length direction, but the flow in the width direction is reliably prevented by the inner wall 20a having the reduced height h1.

  Therefore, as shown in FIG. 6, the sealing agent 5 shaped by the shaping mold member 19 includes a side surface 5a having a height h2 corresponding to the height h1 reduced during shaping. The boundary between the shaped sealant 5 and the workpieces 1 and 2 is clearly defined by the side surface 5a, and is uniform and free from disturbance.

  FIG. 7 is a cross-sectional view showing still another example of the shaping mold member. In FIG. 7, the cross section of the one side of the non-contact part 23 of the shaping | molding die member 22 which concerns on this example is shown. The same applies to the cross section on the other side of the non-contact portion 23.

  As shown in FIG. 7, the shaping mold member 22 includes a contact portion 24 similar to the contact portion 12 of the shaping mold member 7 described above. The non-contact part 23 has the inner wall 23a similar to the inner wall 20a of FIG. A shim plate 25 is embedded in the shaping mold member 22 at a position within a predetermined range away from the contact surface 24a with respect to the workpieces 1 and 2 of the contact portion 24 in a posture parallel to the contact surface 24a.

  For example, when the shaping mold member 22 is molded with silicone, first, a portion of the shaping mold member 22 on the side opposite to the workpieces 1 and 2 from the shim plate 25 is molded. This can be done by placing the shim plate 25 and supplying liquid silicone thereon.

  The reason why the shim plate 25 is embedded in a place away from the contact surface 24a is that it is necessary to ensure the followability of the contact portion 24 with respect to the workpiece 1 or 2. Therefore, based on this viewpoint, the distance from the contact surface 24a to the buried portion is determined.

  That is, if the height of the inner wall 23a is h3 and a predetermined distance smaller than h3 is d, the shim plate 25 exists within the range of the distance (h3-d) to h3 from the contact surface 24a. In this case, for example, the height h3 of the inner wall 23a is 0.55 [mm], the distance d is 0.1 [mm], and the thickness t of the shim plate 25 is 0.05 [mm].

  The shaping of the sealing agent 5 by the shaping mold member 22 is performed in the same manner as the shaping mold member 19 of FIG. At the time of shaping, as in the case of the shaping mold member 19, the height h3 of the inner wall 23a decreases due to the deformation of the shaping mold member 22.

  However, since the shim plate 25 exists, the height of the inner wall 23a is maintained at least at the thickness t of the shim plate 25, for example, 0.05 [mm] or more. Accordingly, it is ensured that the height h2 (see FIG. 6) of the side surface 5a of the shaped sealant 5 after shaping is at least the thickness t of the shim plate 25. Therefore, the boundary between the shaped sealant 5 and the workpieces 1 and 2 is reliably defined by the side surface 5a of the sealant 5, and is uniform and free from turbulence.

  In addition, in order to guarantee the minimum height of the inner wall 23a of the non-contact part 23 at the time of shaping, instead of the shim plate 25, other rigid bodies that are not crushed even when compressed by pressure, such as glass beads, may be used. Good. When a discontinuous shim such as a glass bead is employed, when the contact portion 12 is bent as shown in FIG. 2A, the shim can easily follow the shape of the contact portion 12.
