Disclosure of Invention

Problems to be solved by the invention

The present inventors have developed an apparatus for adhering a planar adherend to an adherend, the adherend having an elastomer material as a base material. However, even if the adhesive body seems to be appropriately attached immediately after the adhesive body is attached to the object to be adhered, the end of the adhesive body may slightly curl up after a lapse of time, and there is room for improvement in this regard.

It is desirable in one aspect of the present disclosure to provide an adhesive device that can suppress the end portion of the adhesive body from rolling up.

Technical scheme

An adhesive device according to an aspect of the present disclosure is an adhesive device configured to attach a planar adhesive body having adhesiveness on at least one surface to a target range set on an object to be adhered. The adhesion device is provided with: a push-out mechanism; a support portion; a conveying mechanism; and a control section. The pushing mechanism is configured to protrude a head member having a guide surface, and push out the adhesive body, which is sent out to the distal end side in the protruding direction of the head member along the guide surface, from the distal end in the protruding direction of the head member. The support portion is configured to support an object to be adhered. The conveying mechanism is configured to be capable of changing the relative position of the pushing mechanism and the supporting portion by moving at least one of the pushing mechanism and the supporting portion. The control unit controls the pushing mechanism and the conveying mechanism so that the adhesive body is pushed out from the distal end of the head member in the protruding direction by the pushing mechanism while moving the distal end of the head member in the protruding direction along the target range by the conveying mechanism, and the adhesive body is stuck to the target range. Further, the control unit is configured to control the pushing mechanism and the conveying mechanism as follows: the method includes the steps of setting a head member to be attached to the adhesive body, and setting a head member to be attached to the adhesive body, wherein the head member is moved in a direction of a movement of the head member, and the adhesive body is pushed out at a speed lower than the movement speed of the head member from the start of the attachment of the adhesive body to the target range to a first time point, and the head member is moved in a direction of the movement of the head member from the first time point to a second time point, and the head member is moved in a direction of the movement of the head member from the second time point to the completion of the attachment of the adhesive body to the target range.

According to the sticking device configured as described above, the pushing mechanism and the conveying mechanism are controlled by the control unit, and the pushing mechanism and the conveying mechanism are operated so that the pushing speed of the sticking body is smaller than the moving speed of the head member during a period from the start of sticking of the sticking body to the target range to a first time point, are operated so that the pushing speed of the sticking body is larger than the moving speed of the head member during a period from the first time point to a second time point, and are operated so that the pushing speed of the sticking body is smaller than the moving speed of the head member during a period from the second time point to completion of sticking of the sticking body to the target range. As a result, in the range from the start of application to the first time point and in the range from the second time point to the completion of application of the adherend to the target range, a tensile stress is generated in the adherend and the adherend is adhered in a state of tension, and therefore, compared with the case where the adherend is in a state of no tension, the adherend can be prevented from being loosened and being peeled from the adherend.

On the other hand, in the range to be bonded from the first time point to the second time point, a compressive stress is generated in the interior of the bonded body. Therefore, unlike the case where tensile stress is generated throughout the entire inside of the adhesive body, the end portion of the adhesive body can be suppressed from being curled up. That is, when tensile stress is generated in the entire interior of the adherend, the adherend is restrained by causing the adherend to adhere to the adherend in the vicinity of the interface with the adherend, while the adherend is not restrained on the side opposite to the adherend, so that shear stress that acts in the opposite direction to the front and back sides is generated in the adherend, and the end of the adherend is likely to be rolled up. On the other hand, if a compressive stress is generated in the interior of the adhesive body in the range from the first time point to the second time point, even if a tensile stress is generated in the portions on both sides, the stretching between both ends of the entire adhesive body can be suppressed, and even if a time elapses after the adhesion of the adhesive body, the curling up of the end portion of the adhesive body can be suppressed.

The pressure-sensitive adhesive device of the present disclosure may further include the following configuration.

(A) For example, the adhesive device may further include: and a pressurizing mechanism configured to pressurize the adhesive body adhered to the target area. In this case, the pressure of the adhesive body by the pressure mechanism can suppress the end portion of the adhesive body from being curled up excellently.

(B) For example, the sticking device may include: carrying a belt; a first reel; a second reel; and a belt driving section. The carrier tape is attached with a plurality of adherends arranged in a row, and the carrier tape is peeled from the adherends when the adherends are attached to the adherends. The first reel is configured to wind a carrier tape and to pay out the carrier tape when the ejecting mechanism is operated. The second reel is configured to take up the carrier tape when the pushing mechanism is operated. The tape drive section holds the carrier tape by a plurality of rollers in the middle of a moving path of the carrier tape from the first reel to the second reel, and feeds out the carrier tape from the upstream side to the downstream side in the moving direction when at least one of the rollers is rotationally driven. The carrier tape is configured to reach a tip end of the head member in the projecting direction along the guide surface when being fed out from the upstream side to the downstream side in the moving direction by the tape driving section, and then move in a direction of being folded back with the tip end of the head member in the projecting direction as a vertex.

(C) For example, the adhesive device may be configured such that a direction perpendicular to the projecting direction of the head member and parallel to the guide surface is set as the width direction of the head member, a first projection and a second projection are provided on both sides in the width direction at the tip end in the projecting direction of the head member, and the carrier tape is folded back with the tip end in the projecting direction of the head member as a vertex in a range between the first projection and the second projection. In this case, the carrier tape can be suppressed from shifting in the width direction at the tip in the protruding direction of the head member.

(D) For example, the conveying mechanism may be constituted by an orthogonal robot that can change the relative positions of the pushing mechanism and the supporting portion by moving the pushing mechanism in the x-axis direction and the z-axis direction. In this case, even if the support portion is not moved, the pushing mechanism can be moved in the x-axis direction and the z-axis direction, and the relative position of the pushing mechanism and the support portion can be changed to a desired position.

Detailed Description

Next, the above-described adhesive device will be described with reference to exemplary embodiments. As shown in fig. 1 and 2, the sticking device 1 includes: a base 2, an ejection mechanism 3, a support 5, a conveyance mechanism 7, and a pressing mechanism 9. As shown in fig. 3, the adhesive device 1 includes a control unit 10.

As shown in fig. 1, the pushing mechanism 3 includes: a base portion 11, a conveying roller 13, a tape driving portion 15, a photosensor 17, a head member 19, and the like. The ejecting mechanism 3 is equipped with a first reel 21 and a second reel 22. A carrier tape 27 is wound around the first reel 21, a plurality of adhesive bodies 25 are attached to the carrier tape 27, and the plurality of adhesive bodies 25 are arranged in a row. The first reel 21 is configured to reel out the carrier tape 27 when the pushing mechanism 3 is operated. The carrier tape 27 pulled out from the first reel 21 is hung on each portion so as to pass through a moving path to the second reel 22 via the transport roller 13, the head member 19, the tape driving unit 15, and the like. The second reel 22 is configured to wind up the carrier tape 27 when the push-out mechanism 3 is operated.

The tape drive unit 15 is configured to nip the carrier tape 27 with a plurality of rollers in the middle of a moving path of the carrier tape 27 from the first reel 21 to the second reel 22, and to feed out the carrier tape 27 from the upstream side to the downstream side in the moving direction when at least one of the rollers is rotationally driven. The photoelectric sensor 17 is configured to detect the position of the adhesive body 25 when the carrier tape 27 is fed from the upstream side to the downstream side in the moving direction.

In the present embodiment, the carrier tape 27 is made of a transparent film, the adhesive bodies 25 are made of an opaque material, and the two adjacent adhesive bodies 25 are attached to the carrier tape 27 with a gap therebetween. Therefore, when the gap between the adhesive body 25 and the adhesive body 25 passes in front of the photosensor 17, the start of passage of the adhesive body 25 (i.e., completion of passage of the gap) and the completion of passage of the adhesive body 25 (i.e., start of passage of the gap) can be detected based on the difference in transmittance of light when the carrier tape 27 and the adhesive body 25 are irradiated with light (infrared light in the case of the present embodiment).

The head member 19 is formed of a metal plate. As shown in fig. 4a and 4B, the upper surface side of the head member 19 serves as a guide surface 19A for guiding the carrier tape 27 toward the projecting direction tip side of the head member 19. The carrier tape 27 reaches the projecting direction tip of the head member 19 along the guide surface 19A, and then moves in a direction of folding back with the projecting direction tip of the head member 19 as a vertex. At this time, as shown in B of fig. 4, the carrier tape 27 feeds the adhesive body 25 to the distal end side in the projecting direction of the head member 19 through the portion that moves to the distal end in the projecting direction of the head member 19 along the guide surface 19A, and peels off the adhesive body 25 when moving in the above-described folding direction. Thereby, the adhesive body 25 is pushed out from the tip of the head member 19 in the protruding direction.

Further, when viewed from the arrow IVA direction shown in fig. 1, the head member 19 becomes a shape having the first protrusion 31 and the second protrusion 32 on both sides in the width direction at the distal end in the protruding direction of the head member 19, as shown in a of fig. 4. In the range between the first convex portion 31 and the second convex portion 32, the carrier tape 27 moves so as to be folded back with the tip in the protruding direction of the head member 19 as the apex. Therefore, if the head member 19 is provided with the first projection 31 and the second projection 32, the carrier tape 27 can be suppressed from being displaced in the width direction at the projecting direction tip end of the head member 19.

The support portion 5 is configured to support the object 91. The support portion 5 is configured to be capable of reciprocating in a direction parallel to the y-axis direction shown in fig. 2. The conveyance mechanism 7 includes: a post 40, a first rail 41, and a second rail 42, etc. The second rail 42 is configured to be reciprocally movable along the first rail 41 in a direction parallel to the x-axis direction shown in fig. 1. The push-out mechanism 3 is configured to be reciprocally movable along the second rail 42 in a direction parallel to the z-axis direction shown in fig. 1 and 2. That is, the conveying mechanism 7 can move the push-out mechanism 3 in the direction along the zx plane. In the case of the present embodiment, the conveying mechanism 7 is constituted by an orthogonal robot that can change the relative positions of the pushing mechanism 3 and the supporting portion 5 by moving the pushing mechanism 3 in the x-axis direction and the z-axis direction.

The pressurizing mechanism 9 includes: a rail portion 51 and a pressing body 53. The pressing body 53 is configured to be reciprocally movable along the rail portion 51 in a direction parallel to the z-axis direction shown in fig. 1 and 2. When the pressure body 53 descends, the pressure body 25 can be pressed at the lower end of the pressure body 53.

As shown in fig. 5a and 5B, the adhesive body 25 is formed in a planar shape. The first surface 251 of the first surface 251 and the second surface 252 of the adherend 25 is a bonding surface that can be bonded to the adherend 91. The adherend 25 has a structure in which an adhesive layer 61 made of an elastic material having adhesiveness and an adhesion-suppressing layer 62 for suppressing the adhesiveness of the adhesive layer 61 are laminated.

In the present embodiment, a thermally conductive elastomer based on an acrylic resin and containing a thermally conductive filler and a plasticizer is used as the elastomer material constituting the adhesive layer 61. More specifically, in the case of the present embodiment, the adhesive layer 61 is made of a thermally conductive elastomer made of a polymer obtained by polymerizing an acrylate-containing monomer as a base material, magnesium hydroxide treated with a higher fatty acid as a thermally conductive filler, and other thermally conductive fillers and plasticizers.

The mixing ratio of these raw material components can be arbitrarily adjusted, but as an example, 100 to 160 parts by weight of magnesium hydroxide and 250 to 330 parts by weight of another thermally conductive filler may be mixed with 100 parts by weight of the polymer. For example, aluminum hydroxide, silicon carbide, boron nitride, and carbon materials such as graphite and carbon nanotubes may be used as the other thermally conductive filler. For example, 6 parts by weight or more of trimellitate can be blended as a plasticizer per 100 parts by weight of the polymer. The adhesive layer 61 may be configured such that the hardness measured by an ASKER rubber durometer type C (manufactured by polymer instruments) is 10 or less. The adhesive layer 61 may have a thermal conductivity of 2W/m.K or more.

In the present embodiment, the adhesive layer 61 is formed to have a thickness of about 0.1mm to 6.0 mm. The adhesion-inhibiting layer 62 was formed of a polyester film having a thickness of 5 μm. However, the thicknesses of the adhesive layer 61 and the adhesion-inhibiting layer 62 are merely representative examples, and are not limited to the specific dimensions illustrated. The polyester film constituting the adhesion-inhibiting layer 62 has flexibility to such an extent that it can be deformed into a shape that comes into close contact with the object to be contacted together with the adhesive layer 61 when the object to be contacted comes into contact with the second surface 252 of the adhesive body 25.

The second surface 252 of the adhesive body 25 is configured such that the adhesive layer 61 protrudes to the outer peripheral side of the adhesion inhibiting layer 62. Thus, the second surface 252 of the adhesive body 25 is provided with the adhesive region 71 having adhesiveness and the adhesion-inhibiting region 72 in which adhesiveness is inhibited. In the case of the present embodiment, the adhesive body 25 is formed to be 27mm square. The adhesive region 71 is formed to have a length of 27mm × a width of 0.15mm, and is provided at a position along two sides orthogonal to the longitudinal direction of the carrier tape 27 among the four sides of the adhesive body 25. By providing such an adhesive region 71, the second surface 252 of the adhesive body 25 is configured to have weaker adhesiveness than the first surface 251.

As described above, as shown in fig. 6a, the plurality of adhesive bodies 25 are attached to the carrier tape 27, the plurality of adhesive bodies 25 are arranged in a row, and the carrier tape 27 is wound around the first reel 21. In the case of the present embodiment, the adhesive bodies 25 are attached to the carrier tape 27 at intervals of 3 mm. The carrier tape 27 is formed of a polyester film having a total length of 62m, a width of 27mm and a thickness of 0.05 mm. The carrier tape 27 was provided with 1m regions to which the adhesive bodies 25 were not attached at both ends. Therefore, the entire length of the region to which the adhesive body 25 is attached is 60 m. The outer diameter of the first reel is 435 mm.

When the carrier tape 27 is wound around the first reel 21, as shown in fig. 6a and 6B, the adhesive bodies 25 are sandwiched between the carrier tape 27 on the inner circumferential side and the carrier tape 27 on the outer circumferential side. At this time, when the adhesive region 71 as described above is provided on the second surface 252 of the adhesive body 25, the second surface 252 of the adhesive body 25 adheres to the carrier tape 27 on the inner peripheral side with a slight adhesive force. Therefore, slack occurring in the carrier tape 27 wound around the first reel 21 can be suppressed.

Since the adhesion-suppressed region 72 is provided on the second surface 252, the adhesion of the second surface 252 is extremely weak as compared with the adhesion of the first surface 251 on which the adhesion-suppressed region 72 is not provided. Therefore, when the carrier tape 27 is paid out from the first reel 21, the adhesive force of the second surface 252 can be prevented from interfering with the paying out of the carrier tape 27. Further, when the carrier tape 27 is paid out from the first reel 21, the carrier tape 27 on the outer peripheral side can be prevented from being peeled off from the adhesive body 25 in a state where the adhesive body 25 is adhered to the carrier tape 27 on the inner peripheral side.

In the present embodiment, the control unit 10 is constituted by a PLC. The PLC is an abbreviation of programmable Logic Controller (programmable Logic Controller). The control unit 10 controls the operations of the above-described pushing mechanism 3, support unit 5, conveying mechanism 7, and pressing mechanism 9. When the adhesive body 25 is attached to the object 91 supported by the support portion 5, the control portion 10 operates the conveying mechanism 7 to move the pushing mechanism 3 from the first position shown in a of fig. 7 to the second position shown in B of fig. 7. Then, the pushing mechanism 3 is moved from the second position shown in B of fig. 7 to the third position shown in C of fig. 7, whereby the projecting direction distal end of the head member 19 is moved along the target range set on the adherend 91. When the push-out mechanism moves from the second position to the third position, the control unit 10 operates the push-out mechanism 3. Thereby, the adhesive body 25 is pushed out from the tip in the protruding direction of the head member 19, and the adhesive body 25 is adhered to the target range.

The control unit 10 controls the respective operation speeds of the pushing mechanism 3 and the conveying mechanism 7 to be the speeds shown in a in fig. 8. Thus, the pushing speed of the adhesive body 25 is smaller than the moving speed of the head member 19 from the time point t0 at which the application of the adhesive body 25 to the target range is started to the first time point t 1. Further, the push-out speed of the adhesive body 25 is greater than the moving speed of the head member 19 during the period from the first time point t1 to the second time point t 2. Further, during the period from the second time point t2 to the time point t3 at which the sticking of the adhesive body 25 to the target range is completed, the pushing-out speed of the adhesive body 25 is smaller than the moving speed of the head member 19.

As shown in B of fig. 8, by such control, the adherend 25 attached to the target area is attached to the target area in a slightly stretched state in the range P1 attached from the attachment start time t0 to the first time t1, and a tensile stress is generated in the adherend 25. In the range P2 where the adhesive body 25 is stuck from the first time point t1 to the second time point t2, the adhesive body 25 is stuck in a slightly pressed state in the target range, and a compressive stress is generated in the adhesive body 25. In the range P3 of the adhesive 25 stuck from the second time t2 to the time t3 at which the sticking of the adhesive 25 to the target range is completed, the adhesive 25 is stuck to the target range in a slightly stretched state, and a tensile stress is generated in the adhesive 25.

Therefore, since the adhesive is adhered in the state where the tension is present in the range P1 and the range P3 shown in B of fig. 8, the adhesive 25 is prevented from being loosened and the adhesive 25 is prevented from being peeled off from the adherend 91, as compared with the case where the tension is not present. On the other hand, in the range P2, a compressive stress is generated inside the adherend 25. Therefore, unlike the case where tensile stress is generated throughout the entire inside of the adhesive body 25, the end portion of the adhesive body 25 can be prevented from being curled up.

When a tensile stress is generated in the entire interior of the adherend 25, the adherend 25 is bound by the adherend 91 adhering to the adherend 25 in the vicinity of the interface with the adherend 91, while the adherend 25 is not bound on the side opposite to the adherend 91. Therefore, shear stress acting in the opposite directions of the front surface and the back surface is generated in the adhesive body 25, and the end portion of the adhesive body 25 is easily rolled up. In contrast, in the above range P2, if a compressive stress is generated inside the adherend 25, even if a tensile stress is generated in the portions on both sides, the entire adherend 25 can be suppressed from being stretched between both ends. Therefore, even when time has elapsed after the adhesion of the adhesive body 25, the end portion of the adhesive body 25 can be prevented from being curled up.

After the adhesive body 25 is adhered to the target range, the control unit 10 moves the support portion 5 from the adhered position shown in a of fig. 9 to the pressed position shown in B of fig. 9. Next, the control unit 10 controls the pressurizing mechanism 9 to move the pressurizing body 53 from the ascending position shown in B of fig. 9 to the descending position shown in C of fig. 9. Thus, the pressure body 53 applies pressure to the adhesive body 25, thereby bringing the adhesive body 25 into close contact with the adherend 91.

According to the above-described adhesive device 1, even when time has elapsed after the adhesion of the adhesive body 25, the end portion of the adhesive body 25 can be prevented from being rolled up.

Although the adhesive device 1 has been described above with reference to the exemplary embodiment, the above-described embodiment is merely an example of one aspect of the present disclosure. That is, the present disclosure is not limited to the above exemplary embodiments, and may be implemented in various forms without departing from the technical spirit of the present disclosure.

For example, in the above embodiment, the pushing mechanism 3 is configured to be moved in the direction along the zx plane by the conveying mechanism 7, but the pushing mechanism 3 side may be fixed and the supporting portion 5 side may be moved so that the pushing mechanism 3 and the supporting portion 5 are displaced to the same relative position. Further, both the pushing mechanism 3 side and the supporting portion 5 side may be moved, and for example, the pushing mechanism 3 side may be configured to be reciprocally movable in parallel with the x-axis direction and the supporting portion 5 side may be configured to be reciprocally movable in parallel with the z-axis direction.

In the above embodiment, the width of the adhesive region 71 is set to 0.15mm, but the width of the adhesive region 71 may be set to be narrower than 0.15mm or wider than 0.15 mm. In the above embodiment, the adhesive regions 71 are provided on two sides of the four sides of the adhesive body 25 that are orthogonal to the longitudinal direction of the carrier tape 27, but the positions where the adhesive regions 71 are provided and the shape of the adhesive regions 71 are not limited to the above example. For example, the adhesive region 71 may be provided at a position along all four sides of the adhesive body 25 (i.e., all the periphery of the adhesion-inhibiting layer 62). The adhesive region 71 may be provided at a position along one side of the four sides of the adhesive body 25, the adhesive region 71 may be provided at a position along two sides different from the above-described example, or the adhesive region 71 may be provided at a position along three sides. Alternatively, a hole may be formed in the adhesion-inhibiting layer 62, so that a portion corresponding to the hole may be an adhesion region.

Note that a plurality of components may realize a plurality of functions of one component in the above embodiments, or a plurality of components may realize one function of one component. Further, a plurality of functions provided by a plurality of components may be realized by one component, or one function realized by a plurality of components may be realized by one component. Further, a part of the configuration of the above embodiment may be omitted.
