Description

Technical Field

[0001] This invention relates to an adhesive device. Background Technology

[0002] Previously, there were known adhesive devices that, after transferring an adhesive film located in a designated transfer area to the circumferential surface of a transfer roller, used the transfer roller to adhere the adhesive film to the component to be adhered in the designated adhesive area.

[0003] Figure 15 This is an explanatory diagram of the adhesive applicator 900 described in Patent Document 1. In the diagram, symbol 10 represents the laminated film, symbol 11 represents the release film, symbol 922 represents the laminated film release roller, and symbol 926 represents the laminated film take-up roller. The adhesive applicator 900 described in Patent Document 1 has a laminated film transport roller 924, a transfer roller 940, and a component transport roller 934 arranged side by side. After the adhesive film is transferred to the circumferential surface of the transfer roller 940 in a designated transfer area A1 on the laminated film transport roller 924, the adhesive film is then adhered to the component 20 by the transfer roller 940 in a designated adhesive area A2 on the component transport roller 934. Furthermore, the transfer roller 940 is in contact with both the laminated film transport roller 924 and the component transport roller 934.

[0004] [Preliminary Technology Documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2006-088480

[0006] However, in the invention described in Patent Document 1, since the transfer roller 940 is in contact with both the laminated film transport roller 924 and the component to be bonded transport roller 934, adjusting the orientation of the transfer roller 940 will affect the transport of the laminated film 10 and the component to be bonded 20. Therefore, there is a problem that the orientation of the transfer roller 940 cannot be adjusted, making it difficult to bond the film with high precision.

[0007] The present invention was made to solve the above-mentioned problems, and its object is to provide an adhesive device capable of adhesively attaching films with high precision. Summary of the Invention

[0008] The present invention relates to an adhesive device that transfers an adhesive film onto the circumferential surface of a transfer roller within a defined transfer area, and adheres the adhesive film to a component to be adhered within the defined adhesive area using the transfer roller. The device is characterized by comprising: a transfer roller for transferring the adhesive film onto the circumferential surface and adhering the adhesive film to the component to be adhered within the adhesive area; and a moving means for relatively moving the transfer roller to the transfer area when transferring the adhesive film onto the circumferential surface of the transfer roller, and for relatively moving the transfer roller to a position separated from both the transfer area and the adhesive area during at least one of the preceding and following stages of transferring the adhesive film onto the circumferential surface of the transfer roller, and for adhering the adhesive film to the component to be adhered. The transfer roller is moved relative to the pasting area; and a pasting film adjustment means is used to adjust the position and orientation of the pasting film on the circumferential surface of the transfer roller at a position separate from both the transfer area and the pasting area, so that the pasting film is in a position corresponding to the position and orientation of the pasted member when the pasting film is pasted onto the pasted member, wherein the pasting film adjustment means includes: a rotation angle adjustment means for adjusting the pasting start position of the pasting film on the circumferential surface of the transfer roller; a width direction adjustment means for adjusting the width direction position of the pasting film corresponding to the width direction position of the pasted member; and a tilt adjustment means for adjusting the angle of the transfer roller relative to the pasted member.

[0009] In this specification, "transfer" refers to the process of moving the adhesive film from the transfer area to the circumferential surface of the transfer roller by rotating the transfer roller while the roller is in contact with the adhesive film located in the transfer area.

[0010] Invention Effects

[0011] According to the bonding apparatus of the present invention, since it includes a bonding film adjustment means, this means adjusts the position and orientation of the bonding film on the circumferential surface of the transfer roller at a position separate from both the transfer area and the bonding area, so that the bonding film is positioned corresponding to the position and orientation of the component to be bonded when the bonding film is bonded to it. Therefore, even if the orientation of the transfer roller is adjusted, it will not affect the conveying of the laminating die or the conveying of the component to be bonded. In this way, the orientation of the transfer roller can be adjusted to achieve high-precision bonding of the bonding film.

[0012] Furthermore, according to the adhesive device of the present invention, since the adhesive film adjustment means includes a rotation angle adjustment means, a width direction adjustment means, and a tilt adjustment means, the position and orientation of the adhesive film on the circumferential surface of the transfer roller can be precisely adjusted so that it is in a position corresponding to the position and orientation of the component to be adhesive.

[0028] The adhesive device of the present invention will now be described with reference to the embodiments shown in the accompanying drawings. The drawings are for illustrative purposes only and do not necessarily reflect actual dimensions.

[0029]

Implementation Method 1

[0030] 1. Structure of the laminated film 10 and the bonded component 20 in Embodiment 1

[0031] Before describing the adhesive device 100 according to Embodiment 1, the laminated film 10 and the adhesive member 20 will be described first. Figure 1 This is a diagram illustrating the laminated film 10, the adhesive film 13, and the adhered member 20 in Embodiment 1. Wherein, Figure 1 (a) is a cross-sectional view of the laminated film 10. Figure 1 (b) is a top view of the pasted membrane 13. Figure 1 (c) is a top view of the pasted component 20. Figure 2 This is a schematic diagram illustrating the adhesion of the adhesive film 13 to the component 20. Wherein, Figure 2 (a) is a schematic diagram showing the situation when the adhesive film 13 is correctly adhered to the specified position. Figure 2 (b) is a schematic diagram showing the situation when the adhesive film 13 is tilted from the specified position. Figure 2 (c) is a schematic diagram of the situation when the adhesive film 13 is pasted to the component in Embodiment 1.

[0032] The laminated film 10 is a long strip film formed by laminating the release film 11 and the adhesive film 12 (see reference). Figure 1 (a)

[0033] The release film 11, for example, is made of PET resin and is used to protect the adhesive surface of the adhesive film 12. Because of the release film 11, the adhesive film 13 can be easily transferred to the transfer roller 140 during transfer printing.

[0034] The adhesive film 12 is a cover film having a thermosetting adhesive material layer on one surface of the cover film body. The thermosetting adhesive material layer can be peeled off from the release film 11 when exposed to air at room temperature, for example. Cuts are formed at certain intervals on the adhesive film 12, allowing it to be divided into adhesive film sheets 13. Alternatively, the adhesive film 12 can be a thin film with pre-formed cuts to form adhesive film sheets, or a forming portion with cuts formed on the adhesive film 12 can be provided on the adhesive device 100, and the adhesive film sheets 13 can be formed before transfer by the transfer roller 140. Alignment marks 14 (see reference 14) are formed on the adhesive film sheets 13 at appropriate positions (four corners in Embodiment 1). Figure 1 (b)).

[0035] The adhesive component 20 is in the shape of a long strip of film. The adhesive component 20 is, for example, a flexible wiring substrate with a conductor pattern formed on it. In this embodiment, the wiring portion is protected by adhesiveting the film 13 into a designated area. Alignment marks 24 (see reference 1) are formed at appropriate positions (four corners in Embodiment 1) in the area 22 where the adhesive film 13 is to be applied. Figure 1 (c)).

[0036] As with conventional pasting devices 900, if the position and orientation of the adhesive film 13 on the transfer roller 140 cannot be adjusted, there may be a situation where the area 22 where the adhesive film 13 is pasted to the member 20 (see reference) may be affected. Figure 2 (b) solid line), the start and end positions of the adhesive patch 13 (refer to) Figure 2 The top or bottom edge of the solid rectangle in the image is offset, or the adhesive film 13 is tilted and offset, or the adhesive film 13 is offset in the width direction. Figure 2 Problems such as the right or left side of the solid rectangle in (b) make it difficult to attach the adhesive film 13 to the attached component 20 with high precision.

[0037] In contrast, in the adhesive device 100 according to Embodiment 1, the adhesive film 13 is transferred onto the circumferential surface of the transfer roller 140 within a designated transfer area A1, and the position and orientation of the adhesive film 13 on the transfer roller 140 are adjusted (see reference). Figure 2 (c) and Figure 8 The product is manufactured by using a transfer roller 140 to adhere the adhesive film 13 to the component 13 within the designated adhesive area A2 (see reference). Figure 2 (a)).

[0038] 2. Structure of the adhesive device 100 according to Embodiment 1

[0039] Next, the structure of the adhesive device 100 according to Embodiment 1 will be described. Figure 3 This is a cross-sectional view of the adhesive device 100 according to Embodiment 1. Figure 4 This is a top view of the main part of the adhesive device 100 according to Embodiment 1. Figure 5 This is an enlarged cross-sectional view of the main part of the pasting device 100 according to Embodiment 1. For the sake of simplicity of explanation, in Embodiment 1, the direction of the axis of the component to be pasted from the axial direction of the laminated film conveying roller 124 is defined as the x-direction, the direction perpendicular to the x-direction and in the same plane as the x-direction is defined as the y-direction, and the vertical direction is defined as the z-direction.

[0040] like Figures 3-5 As shown, the first embodiment of the pasting device 100 includes: a base 110, a laminated film conveying and adjusting mechanism 120, a component to be pasted conveying and adjusting mechanism 130, a transfer roller 140, a moving means 150, a pasting film adjusting means 160, a first camera 170, a second camera 180, and a control unit 190 (see reference). Figure 7 In the adhesive bonding apparatus 100 according to Embodiment 1, other structural elements are mounted on the base 110, the laminated film transport adjustment mechanism 120 is disposed on the -x direction side of the base 110, and the bonded component transport adjustment mechanism 130 is disposed on the +x direction side of the base 110. The control unit 190, which will be described later, is housed inside the base 110.

[0041] like Figure 3 and Figure 4 As shown, the laminated film conveying and adjusting mechanism 120 includes: a release roller 122 that releases the laminated film 10 from below in the +x direction to position the release film 11 on each roller side; a laminated film conveying roller 124 that conveys the release film 11 in the -x direction while rotating the laminated film 10 conveyed from the release roller 122; a winding roller 126 for winding the release film 11; and an auxiliary roller 128 that assists in conveying the laminated film 10 in the conveying direction. Furthermore, since the transfer roller 140 performs the transfer operation of the adhesive film 13 on one side of the circumferential surface of the laminated film conveying roller 124, the area on one side of the adhesive component conveying roller 134 on the circumferential surface of the laminated film conveying roller 124 is the transfer area A1.

[0042] The component conveying and adjusting mechanism 130 includes: a release roller 132 for releasing the component 20 to be bonded in the -x direction; a component conveying roller 134 for conveying the component 20 (product 30) with the film 13 bonded to it in the +x direction while rotating the component 20 conveyed from the release roller 132; a winding roller 136 for winding the component 20 (product 30) with the adhesive film 13 bonded to it; and an auxiliary roller 138 for assisting in conveying the component 20 in the conveying direction. Furthermore, since the transfer roller 140 bonds the adhesive film 13 to the component 20 on the circumferential surface of the component conveying roller 134, located on the side of the transfer roller 140, the area on the circumferential surface of the component conveying roller 134 located on the side of the laminated film conveying roller 124 is the bonding area A2. The transfer area A1 and the bonding area A2 are two opposing areas.

[0043] The transfer roller 140 transfers the adhesive film 13 onto the circumferential surface of the laminated film transport roller 124 in the transfer area A1, and adheres the adhesive film 13 to the adhered member 20 in the adhesion area A2 of the adhered member transport roller 134. The transfer roller 140 is rotatable about an axis extending in approximately the y-direction. The transfer roller 140 is an adhesive roller with an adhesive material (e.g., adhesive rubber) disposed on its surface. It may have only the adhesive material coated on its surface, or the roller itself may be composed of an adhesive material. The adhesive strength of the transfer roller 140 is stronger than the adhesive strength between the adhesive film 12 and the release film 11 in the laminated film 10. The laminating film conveying roller 124, the transfer roller 140, and the component conveying roller 134 are arranged side-by-side along a direction orthogonal to the axis of the laminating film conveying roller 124. That is, the laminating film conveying roller 124, the transfer roller 140, and the component conveying roller 134 are arranged in a straight line along the x-axis (specifically, although the transfer roller 140 may shift slightly due to adjustments, it is generally arranged along a direction orthogonal to the axis of the laminating film conveying roller 124). The transfer roller 140 is positioned between the laminating film conveying roller 124 and the component conveying roller 134, and moves between them.

[0044] When the moving means 150 transfers the adhesive film 13 onto the circumferential surface of the transfer roller 140, it moves the transfer roller 140 to the transfer area A1 (specifically, to the area on the laminated film transport roller 124 that contacts the adhesive film 13). Later in the process of transferring the adhesive film 13 onto the circumferential surface of the transfer roller 140, the transfer roller 140 is moved to a position separate from both the transfer area A1 and the adhesive area A2 (a position separate from both the laminated film transport roller 124 and the component to be bonded transport roller 134). When the adhesive film 13 is bonded to the component to be bonded, the transfer roller 140 is moved to the adhesive area A2 (specifically, to the area on the component to be bonded transport roller 134 that contacts the component to be bonded 20). That is, the moving means 150 causes the transfer roller 140 to reciprocate between the laminated film transport roller 124 and the component to be bonded transport roller 134 (in both the x and -x directions). As the moving means 150, an appropriate structure can be adopted. For example, a platform portion can be arranged on the base 110 with a track extending in the x direction, and a platform portion on the track is equipped with a film adjustment means 160, a transfer roller 140 and a first camera 170, and the platform portion can be moved along the track by a motor or the like.

[0045] The adhesive film adjustment means 160 adjusts the position and orientation of the adhesive film 13 on the circumferential surface of the transfer roller 140 at a position separated from both the transfer area A1 and the adhesive area A2, so that it corresponds to the position and orientation of the adhesive film 13 when it is adhered to the adhesive component 20. The adhesive film adjustment means 160 includes a rotation angle adjustment means 162, a width direction adjustment means 164, and a tilt adjustment means 166.

[0046] The rotation angle adjustment means 162 is used to adjust the starting position of the adhesive film 13 on the circumferential surface of the transfer roller 140. The rotation angle adjustment means 162 is a servo motor used to adjust the rotation angle of the transfer roller 140.

[0047] The width direction adjustment means 164 is a y-axis moving means used to adjust the position of the adhesive film 13 in the width direction (y-direction) corresponding to the width direction of the adhesive member 20. As the width direction adjustment means 164, a suitable structure can be adopted. For example, a structure can be adopted in which a track extending in the y-direction is arranged on the platform of the moving means 150, and a second platform part is arranged on the track via feet, on which the tilt adjustment means 166, the transfer roller 140 and the first camera 170 are mounted, and the second platform part is moved along the track by a motor.

[0048] The tilt adjustment means 166 is used to adjust the angle of the transfer roller 140 relative to the bonding angle of the member to be bonded 20. The "bonding angle" refers to the angle of a predetermined edge on the member to be bonded 20 for bonding the adhesive film 13 relative to a reference (e.g., the angle of an edge extending along the conveying direction of the member to be bonded 20 relative to the -x direction). For proper bonding, the angle of the transfer roller 140 needs to be adjusted so that the area on the member to be bonded for bonding the film 13 is aligned with the adhesive film 13. Furthermore, in Embodiment 1, the angle of the transfer roller 140 relative to the bonding angle corresponds to the angle of the axis of the transfer roller 140 relative to the axis of the member to be bonded conveyor roller 134.

[0049] The tilt adjustment means 166 raises or lowers at least one of the ends of the transfer roller 140 in the +y direction and the -y direction in the z direction (see reference). Figure 6 This controls the tilt of the transfer roller 140.

[0050] A first camera 170 is positioned above the transfer roller 140 and is used to detect the position and orientation of the adhesive film 13 transferred onto the transfer roller 140. In Embodiment 1, since alignment marks are formed at the four corners of the adhesive film 13, the first camera 170 is respectively positioned at the ends of the transfer roller 140 in the y-direction. The detection results of the first camera 170 are sent to the control unit 190.

[0051] The second camera 180 is positioned below the conveyor roller 134 for attaching the component 20 and for detecting the position and orientation of the component 20 to be attached, as well as the position and orientation of the adhesive film 13 attached to the component 20. In Embodiment 1, since alignment marks 24 are formed at the four corners of the area on the component 20 where the adhesive film 13 is attached, a second camera 180 is positioned at each location corresponding to that area. The detection results from the second camera 180 are sent to the control unit 190.

[0052] like Figure 7As shown, the control unit 190 controls the operation of the laminated film transport adjustment mechanism 120, the attached component transport adjustment mechanism 130, the moving means 150, and the adhesive film adjustment means 160 based on the detection results of the first camera 170 and the second camera 180. The control unit 190 outputs signals to the adhesive film adjustment means 160 and the attached component transport adjustment mechanism 130 based on the detection results of the second camera 180. The adhesive film adjustment means 160 and the attached component transport adjustment mechanism 130 adjust the adhesive film 130's adhesive start position on the circumferential surface of the transfer roller 140 via the rotation angle adjustment means 162, adjust the width direction of the adhesive film 130 via the width direction adjustment means 164, and adjust the angle of the transfer roller 140 relative to the attached component 20 and the transport position of the attached component 20 via the tilt adjustment means 166.

[0053] 3. Adjustment method for the adhesive film 13 in Embodiment 1

[0054] Next, the method of adjusting the adhesive membrane 13 by means of adhesive membrane adjustment 160 will be explained. Figure 8 This diagram illustrates the method of adjusting the adhesive membrane 13 using the adhesive membrane adjustment means 160. Among them, Figure 8 (a) shows the case where the adhesive film 13 is adhered to the component 20 without adjusting the transfer roller 140 and in the correct orientation. Figure 8 (b) Shows the adhesive film 13 and the transfer roller 140 before adjustment by the adhesive film adjustment means 160 when the adhesive film 13 is transferred in an incorrect orientation relative to the adhesive member 20.

[0055] The adhesive film adjustment means 160 adjusts the position and orientation of the adhesive film 13 on the circumferential surface of the transfer roller 140 at a position that is separated from both the transfer area A1 and the adhesive area A2, so that its position and orientation correspond to the position and orientation of the adhesive film 13 when it is pasted onto the adhesive component 20.

[0056] (1) When the adhesive film 13 is transferred to the circumferential surface of the transfer roller 140 in the correct position and orientation.

[0057] When the adhesive film 13 is transferred onto the circumferential surface of the transfer roller 140 in the correct position and orientation, such as Figure 8 As shown in (a), without adjusting the position of the adhesive film 13 in the width direction or the angle of the transfer roller 140 by means of adhesive film adjustment 160, the adhesive film 13 is pasted onto the member 20 after adjusting the pasting start position on the circumferential surface of the transfer roller 140.

[0058] (2) When the film 13 is transferred to the circumferential surface of the transfer roller 140 in an incorrect position and orientation.

[0059] If the adhesive film 13 is transferred onto the circumferential surface of the transfer roller 140 in an incorrect position and orientation (e.g., if the angle of the adhesive film 13 is offset relative to the adhesive angle of the member 20 being adhered to), such as Figure 8 As shown in (b), it is necessary not only to adjust the starting position of the adhesive film 13 on the circumferential surface of the transfer roller 140, but also to adjust the position of the adhesive film 13 in the width direction corresponding to the position of the part 20 being adhered to (in Figure 8 (b) Move the transfer roller 140 to the right and adjust the angle of the transfer roller 140 relative to the bonding angle of the part 20 to be bonded (in Figure 8 (b) The transfer roller 140 is tilted so that the left side is lower and the right side is higher, or it is rotated counterclockwise. In this way, the adhesive film 13 is in the correct position, so that the adhesive film 13 can be adhered to the member 20 to be adhered.

[0060] 4. Method for attaching the adhesive film 13 in Implementation Method 1

[0061] Next, the method for attaching the adhesive film 13 in Embodiment 1 will be described. Figure 9 This diagram illustrates the transfer of the adhesive film 13 from the release film 11 to the transfer roller 140. Figure 9 (a)~ Figure 9 (c) is a diagram of each process step. Figure 10 This diagram illustrates the pre-peeling of the front end of the adhesive film 13 in the next process during the transfer of the adhesive film 13 to the transfer roller 140. Figure 10 (a)~ Figure 10 (d) is a diagram of each process step. Figure 11 This diagram shows the detection of the position and orientation of the adhesive diaphragm 13 and the position of the adhered component 20. Figure 11 (a)~ Figure 11 (c) is a diagram of each process step. Figure 12 This diagram illustrates the process of attaching the adhesive film 13 to the component 20 to be adhered. Wherein, Figure 12 (a)~ Figure 12 (c) is a diagram of each process step.

[0062] The method for pasting the adhesive film 13 in Embodiment 1 includes, in sequence, an adhesive film transfer process, an adhesive film adjustment process, and an adhesive film pasting process.

[0063] (1) Film transfer process

[0064] First, the laminated film 10 is conveyed onto the laminated film conveying roller 124 via the laminated film conveying adjustment mechanism 120. For example... Figure 9 As shown in (a), the laminated film transport roller 124 transports the laminated film 10 from the bottom to the top. Then, the transfer roller 140 is moved by the moving means 150 to a position on the laminated film transport roller 124 that contacts the leading edge portion of the laminated film 10 (transfer area A1) (see reference). Figure 9 (a)).

[0065] Next, by moving the transfer roller 140 in the opposite direction to the laminated film transport roller 124 (in... Figure 9 (b) Rotate clockwise to transfer the adhesive film 13 onto the circumferential surface of the transfer roller 140 (refer to...). Figure 9 (c)).

[0066] At this time, while the end portion of the adhesive film 13 is transferred onto the transfer roller 140, the front portion of the adhesive film 13a, which will be transferred onto the transfer roller 140 in the next stage, is also peeled off from the release film 11 and moved onto the transfer roller 140 (see reference). Figure 10 (a), (b)).

[0067] Next, by reversing the transfer roller 140, the front end of the adhesive film 13a is returned to the release film 11 (see reference). Figure 10 (c)).

[0068] Next, the transfer roller 140 is moved toward the component 20 to be bonded (x direction) by the moving means 150, so that it moves away from the laminating film conveying roller 124 (see reference). Figure 10 (d)).

[0069] (2) Adjustment process for attaching the diaphragm

[0070] Next, at a position separated from both the transfer area A1 (laminated film conveyor roller 124) and the bonding area A2 (bonded component conveyor roller 134), the transfer roller 140 is rotated clockwise, and the bonding start position of the bonding film 13 on the transfer roller 140 is monitored by the first camera 170 (refer to...). Figure 11 (a) Next, the transfer roller 140 is rotated further clockwise, and the end position of the adhesive film 13 is detected (see reference). Figure 11 (b)). At this time, adjust the position and orientation of the adhesive film 13 on the circumferential surface of the transfer roller 140 so that it is in a position corresponding to the position and orientation of the adhesive component 20 when the adhesive film 13 is adhered to the adhesive component 20 (refer to...). Figure 8 Additionally, the rotation angle of the transfer roller 140 is adjusted so that the starting position of the adhesive film 13 is consistent with the starting position of the adhesive film 13 on the adhesive member 20 when it comes into contact with the adhesive member 20.

[0071] Additionally, the component to be pasted 20 is transported via the component transport and adjustment mechanism 130, and the starting position of the adhesive film 13 on the component to be pasted 20 is detected by a second camera (see reference). Figure 11 (a)). Next, the component to be pasted 20 is further conveyed, and the end position of the pasting film 13 on the component to be pasted 20 is detected (refer to...). Figure 11 (b) Next, the component to be pasted 20 is conveyed in the opposite direction so that the pasting start position of the component to be pasted 20 is located in the pasting area A2 (the position in contact with the transfer roller 140) (see...). Figure 11 (c)).

[0072] (3) Film pasting process

[0073] Next, the transfer roller 140 is moved toward the side (+y direction) of the component conveying roller 134 by the moving means 150, and the transfer roller 140 is rotated at the same time, so that the bonding start position of the adhesive film 13 is aligned with the bonding start position of the adhesive film 13 on the component 20 (see reference). Figure 12 (a)). Then, the transfer roller 140 and the component conveying roller 134 are rotated to attach the adhesive film 13 to the component 20 (see reference). Figure 11 (b)).

[0074] Then, the adhesive film 13 is confirmed at its starting and ending positions using the second camera 180. While confirming the ending position of the adhesive film 13, the starting position of the next stage of adhesive film 20 can be simultaneously detected. The transfer roller 140 with the adhesive film 13 attached moves towards the laminated film transport roller 124 (in the -x direction).

[0075] Then, by repeating the above operation, the adhesive film 13 can be attached to the component 20 with high productivity.

[0076] 5. Effects of the adhesive device 100 in Implementation Method 1

[0077] According to the adhesive applicator 100 of Embodiment 1, since it includes an adhesive film adjustment means 160, which adjusts the position and orientation of the adhesive film 13 on the circumferential surface of the transfer roller 140 when both the transfer area A1 and the adhesive area A2 are separated, the adhesive film 13 is positioned to correspond to the position and orientation of the adhesive member 20 when the adhesive film 13 is adhered to it. Therefore, even if the orientation of the transfer roller 140 is adjusted, it will not affect the conveying of the laminating mold 10 or the conveying of the adhesive member 20. In this way, the orientation of the transfer roller 140 can be adjusted to achieve high-precision adhesive film adhesion.

[0078] Furthermore, according to the pasting device 100 of Embodiment 1, since the pasting film adjustment means 160 has a rotation angle adjustment means 162, a width direction adjustment means 164 and a tilt adjustment means 166, the position and orientation of the pasting film 13 on the circumferential surface of the transfer roller 140 can be precisely adjusted so that the pasting film 13 is in a position corresponding to the pasted member 20.

[0079] Furthermore, according to the bonding apparatus 100 of Embodiment 1, since it includes a laminated film transport roller 124 for transporting the laminated film 10 on which the adhesive film 13 and the release film 11 are laminated, and a bonded component transport roller 134 for transporting the bonded component 20, the dedicated area of ​​the apparatus can be reduced without preparing a transfer worktable and a bonding worktable. Additionally, since it is not necessary to install equipment for adsorbing the laminated film 10 and the bonded component 20 on these worktables, the dedicated area of ​​the apparatus can also be reduced.

[0080] Furthermore, according to the bonding apparatus 100 of Embodiment 1, since it includes a laminated film transport roller 124 for transporting a laminated film 10 on which the adhesive film 13 and the release film 11 are stacked, and a bonded member transport roller 134 for transporting the bonded member 20, the adhesive film 13 can be arranged along the circumferential surface of the laminated film transport roller 124. In this way, compared to the case where the laminated film is arranged on a flat worktable for transfer printing, the proprietary area of ​​the apparatus can be reduced and made more compact. Similarly, the bonded member 20 can be arranged along the circumferential surface of the bonded member transport roller 134. In this way, compared to the case where the bonded member 20 is arranged on a flat worktable for transfer printing, the proprietary area of ​​the apparatus can be reduced and made more compact.

[0081] Furthermore, according to the first embodiment of the pasting apparatus 100, since it is equipped with a first camera 170 for detecting the position and orientation of the pasting film 13 transferred onto the transfer roller 140, and the pasting film adjustment means 160 adjusts the pasting start position of the pasting film 13 and the angle of the transfer roller relative to the width direction of the pasting film 13 and the pasting angle of the pasted member 20 based on the detection result of the first camera 170, it is possible to perform detection with high precision based on confirming the pasting start position and orientation of the pasting film 13.

[0082] Furthermore, according to the first embodiment of the pasting apparatus 100, since it is equipped with a second camera 180 for detecting the position and orientation of the attached member 20 and the position and orientation of the pasting film 13 pasted on the cut iron member 20, and a pasted member transport adjustment mechanism 130 for adjusting the transport of the pasted member 20, and the pasting film adjustment means 160 and the pasted member transport adjustment mechanism 130 adjust the pasting start position of the pasting film 13 on the circumferential surface of the transfer roller 140, the width direction of the pasting film 13, the angle of the transfer roller 140 relative to the pasted member 20, and the transport position of the pasted member 20 when the transfer roller 140 and the pasted member transport adjustment mechanism 130 are linked, the pasting film 13 can be pasted onto the pasted member 20 with high precision when the pasting film 13 is positioned on the pasted member 20.

[0083] Furthermore, according to the pasting apparatus 100 of Embodiment 1, since the moving means 150 is a means of moving the transfer roller 140, compared with the case where the laminated film conveying adjustment mechanism 120 and the pasted component conveying adjustment mechanism 130 are moved, the mechanism can be miniaturized and the occupied area can be reduced.

[0084] Furthermore, according to the adhesive applicator 100 of Embodiment 1, since it includes a laminated film transport roller 124 for transporting a laminated film 10 on which an adhesive film 13 and a release film 11 are stacked, and a bonded component transport roller 134 for transporting a bonded component 20, the transfer area A1 and the adhesive area A2 can be positioned opposite each other across the transfer roller 140. In this way, the distance the transfer roller 140 is moved by the moving means 150 is shortened, thereby enabling high-speed operation.

[0085] Furthermore, according to the adhesive applicator 100 of Embodiment 1, since the laminated film conveying roller 124, the transfer roller 140, and the component to be adhesive conveying roller 134 are arranged in a direction orthogonal to the axis of the laminated film conveying roller 124, and the transfer roller 140 is disposed between the laminated film conveying roller 124 and the component to be adhesive conveying roller 134, the transfer roller 140 can shorten the travel distance by the moving means 150, thereby achieving the adhesive film 13 adhesive application with high production efficiency.

[0086] Furthermore, according to the adhesive device 100 of Embodiment 1, since the transfer roller 140 can rotate in both directions, when transferring the adhesive film 13, the front end of the adhesive film 13a of the next stage can be temporarily peeled off and then restored (see reference). Figure 10In this way, there is no need for pre-peeling or other processes, and the film 13a to be pasted in the next stage can be easily peeled off from the release film 11. As a result, the adhesive film 13 can be pasted onto the component 20 with high production efficiency.

[0087]

Implementation Method Two

[0088] Figure 13 This diagram illustrates the transfer and pasting of the adhesive film 13 in Embodiment 2. The pasting apparatus 102 in Embodiment 2 has essentially the same structure as the pasting apparatus 100 in Embodiment 1, but differs from Embodiment 1 in that it transfers the adhesive film 13 from a flat surface instead of from the circumferential surface of the laminated film conveyor roller, and pastes the adhesive film onto the flat surface instead of transferring it to the circumferential surface of the conveyor roller of the component to be pasted.

[0089] In implementation method two, such as Figure 13 As shown, the laminated film 10 and the adhered member 20 are positioned opposite each other. The laminated film 10, located above the transfer roller 140, is drawn from... Figure 13 (a) The film 13 is conveyed linearly from left to right and disposed within a predetermined transfer area A1, for example, formed on the worktable. On the underside of the transfer roller 140, the adhesive member 20 is conveyed linearly from right to left and disposed within a predetermined adhesive area A2, for example, formed on the worktable.

[0090] First, such as Figure 13 As shown in (a), the adhesive film 13 is transferred onto the circumferential surface of the transfer roller 140 by rotating the transfer roller 140 in the designated transfer area A1. Alternatively, the adhesive film 13 can be transferred onto the circumferential surface of the transfer roller 140 after the laminated film 10 has been conveyed.

[0091] Next, as Figure 13 As shown in (b), after the transfer roller 140 is moved to a position that is separated from both the transfer area A1 and the adhesive area A2, specifically, after being moved to a position that is separated from both the upper laminated film 10 and the lower adhesive member 20, the position and orientation of the adhesive film 13 on the circumferential surface of the transfer roller 140 are adjusted so that it is positioned corresponding to the position and orientation of the adhesive member 20 when the adhesive film 13 is adhered to the adhesive member 20.

[0092] Next, move the transfer roller 140 downwards, as follows: Figure 13 As shown in (c), the transfer roller 140 is rolled on the pasting area A2 to paste the adhesive film 13 onto the member 20 to be pasted. Alternatively, the adhesive film 13 can be pasted onto the member 20 to be pasted after the member 20 to be pasted is transported.

[0093] In addition, in the second embodiment, although both the transfer area A1 and the pasting area A2 are set as planes, either one can also be set as the circumferential surface of the roller.

[0094] As described above, although the adhesive applicator 102 according to Embodiment 2 differs from the adhesive applicator 100 according to Embodiment 1 in that it transfers the adhesive film from a flat surface rather than from the circumferential surface of the laminating film transport roller, and adheres the adhesive film on a flat surface rather than on the circumferential surface of the component transport roller, it is similar to the adhesive applicator 100 according to Embodiment 1 in that it has an adhesive film adjustment means 160. This adhesive film adjustment means 160 adjusts the position and orientation of the adhesive film 13 on the circumferential surface of the transfer roller 140 at a position that is separate from both the transfer area A1 and the adhesive area A2, so that the adhesive film 13 is in a position corresponding to the position and orientation of the component 20 to be adhered when the adhesive film 13 is adhered to it. Therefore, even if the orientation of the transfer roller 140 is adjusted, it will not affect the transport of the laminating mold 10 and the transport of the component 20 to be adhered. In this way, the orientation of the transfer roller 140 can be adjusted to perform adhesive film adhesion with high precision.

[0095] Furthermore, since the adhesive device 102 of Embodiment 2 has the same structure as the adhesive device 100 of Embodiment 1, except that it transfers the adhesive film from the plane instead of the circumferential surface of the laminated film conveying roller, and that it adheres the adhesive film on the plane instead of the circumferential surface of the conveying roller of the adhered component, it also has the related effects of the adhesive device 100 of Embodiment 1.

[0096] The present invention has been described above based on the embodiments described above, but the present invention is not limited to the embodiments described above. It can be implemented in various ways without departing from the concept, for example, the following modifications can be made.

[0097] (1) The quantity, material, shape, position, size, etc. of the constituent elements described in the above embodiments are examples, and changes can be made within the scope of not impairing the effect of the present invention.

[0098] (2) In the first embodiment described above, although the laminated film conveying roller 124, the transfer roller 140, and the component to be bonded conveying roller 134 are arranged side by side, the present invention is not limited thereto. As long as the transfer roller 140 can be moved to a position where it does not contact either the laminated film conveying roller 124 or the component to be bonded conveying roller 134, the rollers can be appropriately arranged, for example, as follows: Figure 14As shown, a laminating film conveying roller 124 is arranged on the left side, and a component conveying roller 124 is arranged below it. In this case, the transfer roller 140 can move linearly between the laminating film conveying roller and the component conveying roller, or it can move as shown in the diagram. Figure 13 As shown in (b), it can be moved to the right temporarily and then downwards in a roundabout manner. This applies to worktables as well. As long as the transfer area A1 and the pasting area A2 can be moved to a position where the transfer roller does not contact either the transfer area A1 or the pasting area A2 when they are arranged at an angle or orthogonal, the transfer area A1 and the pasting area A2 can be appropriately arranged.

[0099] (3) Although the first camera 170 and the second camera 180 are provided in the above embodiments, the present invention is not limited thereto. A material camera for detecting the position and orientation of the laminated film (adhesive film) may also be provided near the laminated film conveying roller 124. In addition, if the position and orientation are detected by any one of the first camera, the second camera and the material camera, the positional deviation during transfer and pasting can be controlled within an allowable range, so only two or one of the three cameras may be provided.

[0100] (4) In the above embodiments, although the position and orientation of the transfer roller 140 are adjusted after transfer and before pasting, the present invention is not limited to this. For example, the position and orientation of the transfer roller 140 may be adjusted before transfer, or the position and orientation of the transfer roller 140 may be adjusted both before and after transfer.

[0101] (5) In the above embodiments, although a cover film was used as the adhesive film, the present invention is not limited to this. A mask or other suitable film may also be used as the adhesive film. In addition, a mask is a thin film that covers the non-plated area during electroplating on the circuit board.

[0102] (6) In the above embodiments, although a film with a thermosetting adhesive material layer on one surface of the covering film body is used as the adhesive film, the present invention is not limited to this. A film with an adhesive material layer other than a thermosetting adhesive material layer may also be used as the adhesive film, as well as a film with an adhesive material layer composed of an adhesive substance. Furthermore, a film in which the film itself is an adhesive substance may also be used as the adhesive film. In addition, when using a film with an adhesive material layer other than a thermosetting adhesive material layer, it is preferable to appropriately adjust the adhesion strength between the release film and the adhesive film, the adhesion strength between the transfer roller and the adhesive film, and the adhesion strength between the adhesive film and the member to be adhered.

[0103] (7) In the above embodiments, although an adhesive roller is used as a transfer roller, the present invention is not limited thereto. As a transfer roller, an adsorption roller that adsorbs the adhesive film from the adsorption holes formed on the surface of the transfer roller may also be used. As a transfer roller, an electrostatic roller that charges the roller and uses electrostatic force to peel off and transfer the adhesive film for bonding may also be used. Adhesive rollers and these rollers may also be combined.

[0104] (8) In the above embodiments, although the laminated film and the bonded component are conveyed in a roll-to-roll manner, the present invention is not limited thereto. Other conveying means besides roll-to-roll may also be used.

[0105] (9) In the first embodiment described above, although the laminated film conveying adjustment mechanism 120 conveys the laminated film from the bottom to the top, and the bonded member conveying adjustment mechanism 130 conveys the bonded member 20 from the top to the bottom, the present invention is not limited thereto. The laminated film conveying adjustment mechanism 120 may also convey the laminated film from the top to the bottom, and the bonded member conveying adjustment mechanism 130 may also convey the bonded member 20 from the bottom to the top. In this case, the transfer roller 140 may rotate in the same direction during both the transfer and bonding processes. Furthermore, the laminated film 10 may be conveyed from the top to the bottom, and the bonded member 20 may also be conveyed from the top to the bottom, or the laminated film may be conveyed from the bottom to the top, and the bonded member may also be conveyed from the bottom to the top. In this case, since the rotation direction of the transfer roller 140 is opposite during the transfer and bonding processes, the bonded member is bonded from the rear end side during the transfer process.

[0106] (10) In the above embodiments, although the moving means is to move the transfer roller, the present invention is not limited thereto. The moving means can move the laminated film conveying roller 124 or the laminated film conveying adjustment mechanism 120, and can also move the pasted component conveying roller 134 or the pasted component conveying adjustment mechanism 130.
