Description

Method for applying film adhesive material and apparatus for applying film adhesive material

[0001] The present disclosure relates to a method for applying a film adhesive and an apparatus for applying a film adhesive.

[0002] The sealing structure described in JP 2021-89881 A has a plate-shaped conductor, a through hole through which the conductor is inserted, a recess extending from the through hole in a direction perpendicular to the axial direction of the through hole and surrounding the through hole, and a hole portion extending in a first direction perpendicular to the axial direction of the through hole and connecting the through hole and the recess to an external space, and is equipped with a holding member that holds the conductor inserted into the through hole, and a sealing member that has a first sealing portion that seals between the recess and the conductor and a second sealing portion that blocks the hole portion.

[0003] In the past, when joining dissimilar components, a film adhesive was attached to one component, and then the other component was joined to the other component. When attaching the film adhesive to one component, an operator simply wrapped the film adhesive around the component. This could result in air bubbles getting trapped between the film adhesive and the component when the film adhesive was attached to the component.

[0004] An object of the present disclosure is to prevent air bubbles from being trapped between a film adhesive and a member when the film adhesive is attached to the member.

[0005] A method for applying a film adhesive according to a first aspect of the present disclosure includes the steps of wrapping one film adhesive around one end face and both plate surfaces of a heated plate member extending in one direction, pressing the one film adhesive against both plate surfaces, pressing the one film adhesive against the one end face, wrapping another film adhesive around the other end face and both plate surfaces of the heated plate member and overlapping the other film adhesive and the one film adhesive against both plate surfaces, pressing the other film adhesive against both plate surfaces, and pressing the other film adhesive against the other end face.

[0006] A method for applying a film adhesive according to a second aspect of the present disclosure is the method for applying a film adhesive described in the first aspect, wherein in the step of pressing the one film adhesive against both of the plate surfaces and the step of pressing the other film adhesive against both of the plate surfaces, the one film adhesive and the other film adhesive are pressed against both of the plate surfaces by passing the plate member through the clamping portion of a pair of rollers.

[0007] A method for applying a film adhesive according to a third aspect of the present disclosure is the same as the method for applying a film adhesive described in the second aspect, except that the pair of rollers are each biased toward the plate member, thereby pressing the one film adhesive and the other film adhesive against both plate surfaces.

[0008] A film adhesive application device according to a fourth aspect of the present disclosure includes a gripping unit that grips a base end portion of a heated plate member that extends in one direction; a pair of support members across which a film adhesive is stretched and which support the film adhesive; a moving unit that moves the gripping unit and bends the film adhesive stretched across the pair of support members at the end faces of the plate member gripped by the gripping unit, thereby wrapping the film adhesive around the end faces and both plate faces of the plate member; one pressing unit that presses the film adhesive against both plate faces of the plate member that moves together with the gripping unit by the moving unit; and another pressing unit that presses the film adhesive against the end faces of the plate member that has stopped moving.

[0009] A film adhesive application device according to a fifth aspect of the present disclosure is the film adhesive application device described in the fourth aspect, wherein the one pressing portion is provided with a pair of rollers that clamp the moving plate member with a clamping portion.

[0010] A film adhesive application device according to a sixth aspect of the present disclosure is the film adhesive application device described in the fifth aspect, wherein the one pressing portion is provided with a biasing member that biases each of the pair of rollers toward the plate member.

[0011] According to the present disclosure, it is possible to prevent air bubbles from being trapped between a film adhesive and a member when the film adhesive is attached to the member.

[0013] First Embodiment An example of a method for applying a film adhesive and an apparatus for applying a film adhesive according to a first embodiment of the present disclosure will be described with reference to Figures 1 to 5. Note that, in the figures, arrow H indicates the up-down direction (vertical direction) of the apparatus, arrow W indicates the width direction (horizontal direction) of the apparatus, and arrow D indicates the depth direction (horizontal direction) of the apparatus.

[0014] A terminal 10 to which a film adhesive 18 is attached using the film adhesive attachment method according to the first embodiment of the present disclosure is used, for example, in a three-phase terminal block 90 shown in FIG. 1 . The film adhesive 18 is a thin synthetic resin film formed using a thermoplastic resin and is used to join dissimilar materials. For example, WelQuick (registered trademark) manufactured by Resonac Corporation can be used as the film adhesive 18. In this embodiment, the thickness of the film adhesive 18 is, for example, 0.05 mm.

[0015] 1, the terminal 10 is formed using a conductive material and is plate-shaped and extends in one direction, with a pair of plate surfaces 12 and a pair of end surfaces 14 sandwiching the pair of plate surfaces 12 in the short direction of the terminal 10. The terminal 10 is an example of a plate member.

[0016] The film adhesive 18 is rectangular and wrapped around the center of the terminal 10 in the longitudinal direction (one direction). The film adhesive 18 wrapped around the terminal 10 is embedded inside the resin housing of the three-phase terminal block 90, and the resin housing and the terminal 10 are joined together.

[0017] The thickness of the film adhesive 18 shown in each drawing is exaggerated to make it easier to understand the state of the film adhesive 18 .

[0018] 2A, the film adhesive applying device 20 (hereinafter referred to as "applying device 20") includes a gripping unit 30 that grips the plate-shaped terminal 10, a support unit 40 that supports the film adhesive 18, and a moving unit 50 that moves the gripping unit 30 in the up-down direction of the device. Furthermore, the applying device 20 includes a pressing unit 60 that presses the film adhesive 18 against the plate surface 12 of the terminal 10, and a pressing unit 70 that presses the film adhesive 18 against the end surface 14 of the terminal 10.

[0019] 2A, the gripping unit 30 is disposed above the joining device 20 when the joining device 20 is in its initial position before operation. The gripping unit 30 includes a pair of gripping blocks 32 spaced apart in the device width direction, a moving mechanism (not shown), and a heater (not shown).

[0020] The pair of gripping blocks 32 are formed of a metal material in a rectangular parallelepiped shape and are aligned in the width direction of the device. The pair of gripping blocks 32 are moved close to and farther from each other in the width direction of the device by a moving mechanism and are heated by a heater. In this embodiment, the pair of gripping blocks 32 are heated by the heater to, for example, 160°C.

[0021] In this configuration, the pair of gripping blocks 32 sandwich the base end portions of the terminals 10 and grip the terminals 10 so that the terminals 10 protrude toward the front in the device depth direction. Specifically, the pair of gripping blocks 32 sandwich the base end portions of the terminals 10 with the longitudinal direction (one direction) being the device depth direction and the plate thickness direction being the device width direction. The pair of gripping blocks 32 then grip the terminals 10 so that the terminals 10 protrude toward the front in the device depth direction. Furthermore, the heated gripping blocks 32 heat the terminals 10.

[0022] 2A, the support portion 40 is disposed below the terminals 10 protruding from the pair of gripping blocks 32. The support portion 40 includes a pair of support blocks 42 spaced apart in the device width direction. The support blocks 42 are an example of a support member.

[0023] The pair of support blocks 42 are formed of a metal material in a rectangular parallelepiped shape and are arranged side by side with a gap in the width direction of the device. Furthermore, the upper surfaces 42a of the pair of support blocks 42 are each formed with a restriction recess 44 for restricting the support position of the film adhesive 18.

[0024] In this embodiment, for example, the gap between the pair of support blocks 42 is set to 1.5 times the plate thickness of the terminal 10. In other words, if the thickness of the terminal 10 is 2 mm, the gap between the pair of support blocks 42 is set to 3 mm.

[0025] In this configuration, the film adhesive 18 is placed on the restricting recesses 44 formed on the upper surfaces 42a of the pair of support blocks 42. As a result, the film adhesive 18, which is positioned by the restricting recesses 44, is supported by being stretched across the pair of support blocks 42.

[0026] 2A, the moving unit 50 is disposed on the far side in the depth direction of the device relative to the gripping unit 30 and extends in the up-down direction of the device. The far side of the gripping unit 30 in the depth direction of the device is attached to the moving unit 50, and the moving unit 50 moves the gripping unit 30 in the up-down direction of the device.

[0027] In this configuration, the moving unit 50 moves the gripping unit 30 downward from the initial position, thereby bending the film adhesive 18 stretched across the pair of support blocks 42 at one end surface 14 of the terminal 10 gripped by the gripping unit 30, as shown in Figures 2(A) and 2(B). As a result, the film adhesive 18 is wrapped around one end surface 14 and both plate surfaces 12.

[0028] 2A, the pressing unit 60 is disposed below the support unit 40 and includes a pair of rollers 62 and a pair of support members 64 that rotatably support the pair of rollers 62. The pressing unit 60 further includes a biasing member 66 that biases the rollers 62 via the support members 64. Here, biasing refers to applying a force in one direction. The pressing unit 60 is an example of one pressing unit.

[0029] 2A, a pair of rollers 62 are provided, with their axial direction extending in the depth direction of the device and aligned with a gap in the width direction of the device. In this embodiment, as an example, the gap between the pair of rollers 62 is set to 0.5 times the plate thickness of the terminal 10. In other words, if the terminal thickness is 2 mm, the gap between the pair of rollers 62 is set to 1 mm. By providing a gap between the pair of rollers 62 in this way, damage to the film adhesive 18 is suppressed.

[0030] The outer circumferential portion of the roller 62 is formed using silicone resin, and the hardness of this portion is Shore A hardness 50. In this way, by forming the outer circumferential portion of the roller 62 using silicone resin, the film adhesive 18 is prevented from sticking to the roller 62. Note that forming the outer circumferential portion of the roller 62 using silicone resin is just one example, and other materials may be used for the outer circumferential portion of the roller 62 as long as they can prevent the film adhesive 18 from sticking to the outer circumferential portion of the roller 62.

[0031] 2A, a pair of support members 64 are provided, and one support member 64 is U-shaped and open on the side facing the other support member 64. The rollers 62 are rotatably supported at both ends of the support member 64.

[0032] 2A, a pair of urging members 66 are provided, and are arranged outward in the device width direction relative to the rollers 62. Specifically, the urging members 66 are compression coil springs, and are arranged to extend in the device width direction, with one end of the urging members 66 attached to the support member 64 and the other end of the urging members 66 attached to a frame member (not shown).

[0033] In this configuration, when the terminal 10 moved by the moving unit 50 is sandwiched between the sandwiching portions of the pair of rollers 62, the film adhesive 18 is pressed against the plate surface 12 of the terminal 10 by the biasing force of the biasing member 66, as shown in Fig. 3(A) . In this embodiment, the pressing force with which the biasing member 66 presses the film adhesive 18 against the plate surface 12 of the terminal 10 is set to 5 [N], for example. Here, the sandwiching portion is the portion where the pair of rollers 62 face each other.

[0034] Furthermore, the relative positions of the rollers 62 and the support block 42 in the vertical direction of the device are determined so that the film adhesive 18 separates from the support block 42 after the terminal 10 is clamped between the clamping portions of the pair of rollers 62.

[0035] 2A, the pressing portion 70 is disposed below the pressing portion 60, and includes a pressing base 72 and a biasing member 74 that biases the pressing base 72 toward the terminal 10. The pressing portion 70 is an example of another pressing portion.

[0036] 2A, the press table 72 has a rectangular parallelepiped shape extending in the depth direction of the device. The upper surface portion of the press table 72 is formed using silicone resin, and the hardness of this portion is Shore A hardness 50. In this way, by forming the upper surface portion of the press table 72 using silicone resin, the film adhesive 18 is prevented from sticking to the press table 72. Note that using silicone resin to form the press table 72 is just one example, and other materials may be used as long as they can prevent the film adhesive 18 from sticking to the upper surface portion of the press table 72.

[0037] 2A, the urging member 74 is disposed below the pressing base 72. Specifically, the urging member 74 is a compression coil spring that is disposed so as to extend in the vertical direction of the device, with one end of the urging member 74 attached to the pressing base 72 and the other end of the urging member 74 attached to a frame member (not shown).

[0038] In this configuration, the moving unit 50 stops the moving gripping unit 30 when it presses the moving terminal 10 against the pressing base 72. As a result, as shown in Fig. 3B, the film adhesive 18 is pressed against the end surface 14 of the terminal 10 by the biasing force of the biasing member 74. In this embodiment, the pressing force with which the biasing member 74 presses the film adhesive 18 against the end surface 14 of the terminal 10 is set to 5 [N], for example.

[0039] (Operation) Next, a description will be given of a film adhesive applying method (hereinafter referred to as "applying method") for applying one film adhesive 18 and another film adhesive 18 to the terminal 10 using the applying device 20. For convenience of explanation, the one film adhesive 18 will be referred to as film adhesive 18a, and the other film adhesive 18 will be referred to as film adhesive 18b.

[0040] 2A , when the joining device 20 is in a non-operating state, the gripping unit 30 is located in an upper portion of the joining device 20. In this state, the pair of gripping blocks 32 are moved toward and away from each other using the approach / detachment mechanism, whereby the pair of gripping blocks 32 sandwich the base end portions of the terminals 10 to grip the terminals 10. The terminals 10 extend in the depth direction of the device and are positioned such that the thickness direction of the terminals 10 is the width direction of the device. Furthermore, the heaters provided in the pair of gripping blocks 32 are operated, whereby the terminals 10 are heated.

[0041] 2A, the film adhesive 18a is placed in the restricting recesses 44 formed on the upper surfaces 42a of the pair of support blocks 42, and the pair of support blocks 42 support the film adhesive 18a in a positioned state. In this way, the film adhesive 18a is stretched across the pair of support blocks 42.

[0042] 2(B) , the moving unit 50 moves the gripping unit 30 gripping the terminal 10 downward, whereby the film adhesive 18a stretched across the pair of support blocks 42 is bent at one end surface 14 of the terminal 10, which moves together with the gripping unit 30. The film adhesive 18a is then wrapped around one end surface 14 and both plate surfaces 12 (wrapping process).

[0043] 3A, the moving unit 50 moves the gripping unit 30 gripping the terminal 10 downward, so that the moving terminal 10 passes through the gripping portions of the pair of rollers 62 while being sandwiched between them, and the film adhesive 18a is pressed against the plate surface 12 of the terminal 10 by the biasing force of the biasing member 66 (pressing process against the plate surface).

[0044] 3(B), the moving unit 50 moves the gripping unit 30 gripping the terminal 10 downward, and stops the moving gripping unit 30 when it presses the terminal 10 against the pressing base 72. As a result, the film adhesive 18a is pressed against the end face 14 of the terminal 10 by the biasing force of the biasing member 74 (pressing process against the end face).

[0045] 4A, the moving unit 50 moves the gripping unit 30 gripping the terminal 10 upward to return it to its initial position. In this state, the film adhesive 18a is attached to one end surface 14 and both plate surfaces 12 of the terminal 10.

[0046] Thereafter, the terminal 10 is released from the gripping portion 30, and one end face 14 of the terminal 10 facing downward is turned upward, and the other end face 14 facing upward is turned downward. In this state, as shown in Fig. 4(B) , the pair of gripping blocks 32 clamps and grips the base end portion of the terminal 10.

[0047] Furthermore, by placing the film adhesive 18b in the restricting recesses 44 formed on the upper surfaces 42a of the pair of support blocks 42, the film adhesive 18b is supported in a state where it is positioned on the pair of support blocks 42. In this way, the film adhesive 18b is stretched across the pair of support blocks 42.

[0048] Then, by repeating the above-described operation, the film adhesive 18 is wrapped around the terminal 10 as shown in Fig. 5. Specifically, the film adhesive 18 is wrapped around the terminal 10 in a state where both end portions of the film adhesive 18a and both end portions of the film adhesive 18b overlap on both plate surfaces 12 of the terminal 10.

[0049] (Summary) As described above, in the attachment method and attachment device 20, the film adhesive 18 is pressed against the plate surface 12 and the end surface 14 of the terminal 10. As a result, in the attachment method and attachment device 20, it is possible to prevent air bubbles from being trapped between the terminal 10 and the film adhesive 18 when attaching the film adhesive 18 to the terminal.

[0050] Furthermore, in the bonding method and bonding device 20, in the pressing step against the plate surface, the moving terminal 10 is sandwiched between the clamping portions of the pair of rollers 62, so that the film adhesive 18 is pressed against both plate surfaces 12 of the terminal 10. As a result, in the bonding method and bonding device 20, compared to when the film adhesive 18 is pressed against the plate surface 12 of the terminal 10 using a non-rotatable pressing member, it is possible to effectively prevent air bubbles from getting between the terminal 10 and the film adhesive 18 when bonding the film adhesive 18 to the terminal 10.

[0051] Furthermore, in the attachment method and attachment device 20, the film adhesive 18 is pressed against the plate surface 12 of the terminal 10 by the biasing force of the biasing member 66. As a result, in the attachment method and attachment device 20, the film adhesive 18 can be pressed against both plate surfaces 12 of the terminal 10 with the same force across the entire plate surface 12.

[0052] Second Embodiment An example of a film adhesive application method and a film adhesive application device according to a second embodiment of the present disclosure will be described with reference to Figures 6 and 7. Note that, with regard to the second embodiment, differences from the first embodiment will be mainly described.

[0053] (Overall configuration of film adhesive applying device 120) As shown in Fig. 6(B) and Fig. 7(A), the film adhesive applying device 120 (hereinafter referred to as "applying device 120") according to the second embodiment is provided with a moving unit 130 that moves and is positioned above the support part 40 in a state in which the pressing base 72 presses the film adhesive 18a against the end face 14 of the terminal 10. Note that the moving part 50 (see Fig. 2) is omitted in Figs. 6 and 7.

[0054] The moving unit 130 is configured to be moved by a moving member (not shown), and includes a pair of limiting blocks 142, a pressing portion 160, and a pressing portion 170, as shown in FIG. 7(A).

[0055] 7A, a pair of limiting blocks 142 are provided. Each limiting block 142 is provided above a pair of support blocks 42, with a gap between them. This prevents the portion of the film adhesive 18 stretched across the support blocks 42 that is in contact with the support blocks 42 from floating upward.

[0056] 7A, the pressing portion 160 is disposed above the limiting block 142. The pressing portion 160 has a configuration similar to that of the pressing portion 60, and includes a pair of rollers 162, a pair of support members 164 that rotatably support the pair of rollers 162, and a biasing member 166 that biases the rollers 162 toward the terminal 10 via the support members 164. The pressing portion 160 is an example of a pressing portion.

[0057] 7A, pressing portion 170 is disposed above pressing portion 160. Pressing portion 170 is configured upside down relative to pressing portion 70, and includes a pressing base 172 and a biasing member 174 that biases pressing base 172 toward terminal 10. Pressing portion 170 is an example of another pressing portion.

[0058] (Operation) Next, a method for attaching the film adhesive 18a and the film adhesive 18b to the terminal 10 using the attachment device 120 will be described.

[0059] First, as shown in FIGS. 6A and 6B, the terminal 10 is moved downward, so that the film adhesive 18 a is attached to one end surface 14 and both plate surfaces 12 of the terminal 10 .

[0060] 6B and 7A, the film adhesive 18b is supported by a pair of support blocks 42. The moving unit 130 is moved by a moving member (not shown) to a position above the support portion 40.

[0061] 7(A) and 7(B), by moving the terminal 10 upward, the film adhesive 18b is attached to the other end surface 14 of the terminal 10 and both plate surfaces 12. In this way, the film adhesive 18 is wrapped around the terminal 10 with both end portions of the film adhesive 18a and both end portions of the film adhesive 18b overlapping on both plate surfaces 12 of the terminal 10 (see FIG. 5).

[0062] Third Embodiment An example of a film adhesive application method and a film adhesive application device according to a third embodiment of the present disclosure will be described with reference to Figures 8 and 9. In this embodiment, the cross-sectional shape of the terminal 10 is different from that of the first embodiment, and therefore the configuration of the application device 220 is also different. Note that, with regard to this embodiment, differences from the first embodiment will be mainly described.

[0063] The terminal 10 is, for example, a bus bar, and has a rectangular, e.g., substantially square, cross section in the short direction. In other words, the plate member includes not only flat members such as the terminal 10 of the first and second embodiments, but also rod-shaped members.

[0064] The gripping block 32 of the gripping portion 30 has a recess 32A into which the terminal 10 fits. The gap between the pair of support blocks 42 of the support portion 40 is set to be larger than the thickness of the terminal 10, for example, by about 1 to 2 mm. As shown in FIG. 8A , when the terminal 10 is above the support portion 40, the pressing base 72 is positioned in the vertical direction, extending from between the pair of support blocks 42 to between the pair of rollers 62. At this time, the height of the top surface of the pressing base 72 is the same as the bottom surface of the film adhesive 18a, for example. The width of the pressing base 72 is the same as the width of the terminal 10, for example.

[0065] (Operation) Next, a method for attaching the film adhesive 18a and the film adhesive 18b to the terminal 10 using the attachment device 120 will be described.

[0066] 8(A) and 8(B), the terminal 10 held in the recessed portions 32A of the pair of gripping blocks 32 is moved downward, whereby the film adhesive 18a is attached to one end face 14 and both plate surfaces 12 of the terminal 10. At this time, the film adhesive 18 is pressed against one end face 14 of the terminal 10 by the pressing base 72, which receives the urging force of the urging member 74, and is also pressed against the plate surfaces 12 of the terminal 10 by the rollers 62, which receive the urging force of the urging member 66.

[0067] 9(A) and 9(B), the terminal 10 is released from the gripping portion 30, and one end face 14 of the terminal 10 facing downward is turned upward, and the other end face 14 facing upward is turned downward. In this state, the base end portion of the terminal 10 is sandwiched and gripped by the recesses 32A of the pair of gripping blocks 32.

[0068] Furthermore, by placing the film adhesive 18b on the restricting recesses 44 (FIG. 4) formed on the upper surfaces 42a of the pair of support blocks 42, the film adhesive 18b is supported in a state where it is positioned on the pair of support blocks 42. In this way, the film adhesive 18b is stretched across the pair of support blocks 42.

[0069] Then, by repeating the above-described operation, the film adhesive 18 is wrapped around the terminal 10. Specifically, the film adhesive 18 is wrapped around the terminal 10 in a state where both end portions of the film adhesive 18a and both end portions of the film adhesive 18b overlap on both plate surfaces 12 of the terminal 10.

[0070] Unlike the first embodiment, in which the film 18a is pressed against both plate surfaces 12 of the terminal 10 and then pressed against the end surface 14, the present embodiment presses the film 18a against the end surface 14 from the beginning of attachment. Therefore, even if the end surface 14 has a relatively large width, it is possible to prevent air bubbles from entering between the terminal 10 and the film adhesive 18.

[0071] While the present disclosure has been described in detail with respect to a specific embodiment, it will be apparent to those skilled in the art that the present disclosure is not limited to such an embodiment and that various other embodiments are possible within the scope of the present disclosure. For example, in the above embodiment, the terminal 10 is heated by the gripping portion 30, but a preheated terminal 10 may be gripped by the gripping portion.

[0072] Furthermore, in the above embodiment, the film adhesive 18 is wrapped around the terminal 10 formed using a metal material, but the film adhesive 18 may also be wrapped around a member formed using another material.

[0073] Furthermore, in the above embodiment, the terminals 10 extend in the depth direction of the device (in one direction), but it is sufficient that the terminals in the portion around which the film adhesive 18 is wrapped extend in one direction.

[0074] Furthermore, in the first embodiment, the film adhesive 18 is wrapped around the terminal 10 by moving the gripping portion 30, but the film adhesive 18 may be wrapped around the terminal 10 by moving the support portion 40, the pressing portion 60, and the pressing portion 70 without moving the gripping portion 30.
