Description

Technical Field

[0001] The present invention relates to a tape sticking device for sticking an ACF tape to a substrate or the like. Specifically, the present invention relates to a tape sticking device capable of improving the accuracy of the sticking position by keeping the tension of the ACF tape constant without significantly varying the tension even during the chucking operation at the time of sticking.

Background Art

[0002] A tape of an anisotropic conducting film (hereinafter abbreviated as an ACF tape) used for mounting electronic components is composed of a peeling film and a sticking portion made of a thermosetting resin containing conductive particles. This ACF tape is supplied in a state of being wound around a tape reel, and a necessary amount is unwound from the reel by a chuck, conveyed, and then stuck to an object to be stuck such as a substrate, and then the sticking is completed by crimping with a crimping tool. After the sticking, the sticking portion is stuck to the object to be stuck by peeling the peeling film of the ACF tape. Further, the peeling film, which is the remaining portion from which the sticking portion has been peeled, is recovered. Furthermore, the peeling film is recovered by being stored in a recovery container by its own weight or suction (for example, see Patent Documents 1 and 2), or by being wound up by a winding reel. If such an ACF tape is stretched, shrunk, or twisted, it will have adverse effects such as the sticking position in the length direction of the tape being displaced, the positional accuracy of the electronic component being reduced, and the conductive performance being deteriorated. Therefore, it is required to control the tension so that the tension (tension) is maintained within a predetermined range and no twisting occurs, and then convey the tape.

[0003] In an image display module such as a liquid crystal display module, it is preferred that the module thickness is thinner and the screen frame is thinner. To meet this requirement, in the manufacture of an image display module, the terminals arranged at the connection terminal portion of the substrate tend to be miniaturized and the pitch becomes narrower. And in order to cope with this miniaturization and the connection terminal portion with a narrow pitch, it is required that the width of the ACF tape be made thinner than 1 mm. For example, when the width is 0.6 mm, the positional deviation in the length direction of the ACF tape needs to be within 30 μm to within 50 μm, and higher-precision accuracy of the sticking position is required. This high-precision sticking position accuracy requires higher-precision tension control.

[0004] Conventional means for controlling the tension of the ACF tape include, on the unwinding side, a combination of a dancer roller or a motor that supports the tape and a permanent torque (see, for example, Patent Document 1). Further, as means for controlling the tension on the recovery side, controlling the tension by clamping and moving a chuck or a clamper (see, for example, Patent Document 1), or controlling the tension by winding with a take-up reel can be mentioned. These tension controls on the recovery side are not as precisely controlled as the tension control on the unwinding side.

Summary of the Invention

Problems to be Solved by the Invention

[0006] On the other hand, the conveyance of the ACF tape is not maintained at a constant speed, and it is necessary to stop the ACF tape while being clamped by a chuck for attachment. Then, during the clamping, releasing, and movement during clamping for feeding by the chuck, a change in the tension between the chuck and the recovery part occurs, resulting in a displacement of the ACF tape due to sagging or the like. This displacement is more likely to occur as the width of the ACF tape becomes narrower and the tension to be maintained becomes smaller, and finer tension control has been required.

[0007] The present invention has been made in view of the above circumstances, and even for a narrow ACF tape with a small tension to be maintained, it is possible to keep the tension of the ACF tape constant without significantly varying the tension during the chuck operation at the time of attachment, and to provide a tape attachment device capable of eliminating the displacement of the ACF tape.

Means for Solving the Problems

[0008] 1. In a tape attachment device for attaching a sticking portion of a tape in which at least a release film and a sticking portion are laminated to an object to be stuck, a pay-out reel around which the tape is wound, a pay-out dancer that applies tension to the tape unwound from the pay-out reel, a crimping portion that presses the sticking portion of the tape passing through the pay-out dancer against the object to be stuck and crimps the sticking portion to the object to be stuck, a chuck portion that grips the release film, which is the remaining portion from which the sticking portion has been peeled off from the tape by the crimping of the crimping portion, and feeds out the release film, a take-up dancer that applies a tension of the same magnitude as the tension to the release film fed out by the chuck portion, and a take-up reel that winds up the release film passing through the take-up dancer, and is characterized by comprising these. 2. The tape attachment device according to 1., wherein each of the pay-out dancer and the take-up dancer includes a balance bar, a rotation axis that serves as a fulcrum for the swinging of the balance bar, and a guide roller provided at one end side end of the balance bar. 2. The tape sticking device according to 2 above, wherein the rotation axes of the balance bars of the pay-out dancer and the take-up dancer are disposed on the same axis as the centers of the pay-out reel and the take-up reel, respectively. 4. The tape sticking device according to 2 or 3 above, wherein the rotation axis of the balance bar of the pay-out dancer and the take-up dancer is located at the center of the balance bar. 5. The device is provided with a locking part for locking the sticking part to the sticking object on the sticking part. The locking part includes a locking stage for placing the sticking object, a component locking part for placing and locking the sticking component on the sticking part, and a locking control part for controlling the locking stage and the component locking part. The locking stage is equipped with a stage camera and is installed on the base so as to be movable horizontally. The component locking part is equipped with a component locking part camera and is disposed above the base so as to be movable horizontally. The base is provided with a reference point marker that can be photographed by the stage camera and the component locking part camera. After the locking control part moves the locking stage horizontally to a position where the stage camera can photograph the reference point marker, it photographs the reference point marker, and then analyzes the position of the photographed reference point marker to perform horizontal position correction. The tape sticking device according to 4 above, wherein after the component locking part is moved horizontally to a position where the component locking part camera can photograph the reference point marker, the reference point marker is photographed, and then the position of the photographed reference point marker is analyzed to perform horizontal position correction.

Advantages of the Invention

[0009] According to the present invention, it has been found that when an ACF tape less than 1 mm is attached, misalignment is likely to occur due to fluctuations in the tape tension caused by the operation of the chuck portion, particularly the difference in tension between the unwinding side and the winding side when the chuck portion releases the tape. By biasing both the unwinding side and the winding side of the tape with dancers having the same configuration so as to always have the same tension and the same tension accuracy, even for a narrow tape that requires reducing the tension to be maintained, the tension of the tape can be kept constant without greatly fluctuating during the chuck operation at the time of attachment, and misalignment of the tape can be eliminated. For this reason, it is possible to eliminate misalignment of an ACF tape that requires high-precision position adjustment even if it is narrow. There is no shock during idling switching like a permatorque, and the tension of the tape does not greatly fluctuate.

[0010] When the unwinding dancer and the winding dancer each include a balance bar, a rotation shaft that serves as a fulcrum for the swing of the balance bar, and a guide roller provided at one end of the balance bar, since a weight is provided at a position away from the tape, the weight attachment position is farther from other guide rollers and the tape than a dancer roller in which a weight is provided at the same position as a conventional guide roller or a permatorque in which an adjustment means is integrated. Therefore, in particular, the operation of attaching a lightweight weight is easy and tension adjustment is easy.

[0011] When the rotation shafts of the balance bars of the unwinding dancer and the winding dancer are disposed on the same axis as the centers of the unwinding reel and the winding reel, respectively, since the center of the swing of the balance bar is coaxial with the center of each reel, the distance between the guide roller and the center of each reel does not change due to the swing of the balance bar. Therefore, the distance between the guide roller and the tape coming out of each reel does not change, and since the tape does not move, it is possible to suppress a tension change caused by the sliding resistance due to the rotation of the guide roller or the feeding of the reel, and eliminate misalignment of the tape accompanying the change in distance.

[0012] When the rotation axes of the balance bars of the pay - out dancer and the take - up dancer are located at the center of the balance bars, the end on the other side where the weight of the balance bar is provided can be separated from each reel by about the same distance as the guide roller, so the operation of attaching the weight is easy and the tension adjustment is easy.

[0013] The attaching part has a locking part for locking the attaching component to the attaching part attached to the object to be attached. The locking part includes a locking stage for placing the object to be attached, a component locking part for placing and locking the attaching component on the attaching part, and a locking control part for controlling the locking stage and the component locking part. The locking stage is equipped with a stage camera and is installed on the base so as to be movable in the horizontal direction. The component locking part is equipped with a component locking part camera and is arranged above the base so as to be movable in the horizontal direction. The base is provided with a reference point marker that can be photographed by the stage camera and the component locking part camera. The locking control part moves the locking stage in the horizontal direction to a position where the stage camera can photograph the reference point marker, then photographs the reference point marker, and then analyzes the position of the photographed reference point marker to perform position correction in the horizontal direction. When the component locking part is moved in the horizontal direction to a position where the component locking part camera can photograph the reference point marker, then the reference point marker is photographed, and then the position of the photographed reference point marker is analyzed to perform position correction in the horizontal direction, the positional deviation caused by the repeated horizontal movement of the stage and the gripping part can be configured with the base as a reference, and accurate alignment can be repeatedly performed even when using a narrow tape.

Best Mode for Carrying Out the Invention

[0015] The matters shown here are illustrative and for exemplarily explaining embodiments of the present invention, and are described for the purpose of providing an explanation that is considered to be the most effective and easy-to-understand for the principles and conceptual features of the present invention. In this regard, it is not intended to show more structural details of the present invention than necessary for a fundamental understanding of the present invention, and it is to clarify for those skilled in the art how some forms of the present invention are actually embodied by the description in combination with the drawings.

[0016] This tape sticking device 1 is a device for sticking a tape 2 for crimping and fixing a sticking object 91 and a sticking component 92 to the sticking object 91. This tape sticking device 1 is a tape sticking device that sticks the sticking portion of a tape in which at least a release film and a sticking portion are laminated to a sticking object. As illustrated in FIGS. 1 and 2, a pay-off reel 11 around which the tape 2 is wound, a pay-off dancer 12 that applies tension to the tape 2 unwound from the pay-off reel 11, a crimping portion 13 that presses the sticking portion 21 of the tape 2 passing through the pay-off dancer 12 against the sticking object 91 to crimp the sticking portion 21 to the sticking object 91, a chuck portion 14 that grips the release film 22 that is the remaining portion from which the sticking portion 21 has been peeled off from the tape 2 by the crimping of the crimping portion 13 and feeds out the release film 22, a take-up dancer 15 that applies a tension of the same magnitude as the tension to the release film 22 fed out by the chuck portion 14, and a take-up reel 16 that winds up the release film 22 passing through the take-up dancer 15.

[0017] The sticking object 91 stuck by this tape sticking device 1 is a substrate such as an image display module or a substrate of an electronic circuit such as a flexible substrate, but is not limited thereto, and may be a support member or the like for fixing the various substrates. Further, the sticking component 92 to be stuck is an electronic component, wiring, or the like disposed on the sticking object 91.

[0018] The tape 2 used in the tape sticking device 1 includes an attachment portion 21 made of a resin film to be attached to the object to be attached, and a release film 22, and these are laminated (not shown). Further, the attachment portion 21 may be sandwiched between the release film 22 and the cover film 23. The tape 2 is usually an ACF tape in which the attachment portion 21 is an anisotropic conductive film, but is not limited thereto, and may be a resin tape having no conductivity and used for fixing parts, or may be a conductive resin tape having conductivity on the entire surface or a metal foil tape coated with an adhesive. The width of the tape 2 is not particularly limited, but may be 0.4 to 10 mm (preferably 0.5 to 5 mm). In particular, in the case of a narrow tape having a width of 0.4 to 1.0 mm (preferably 0.5 to 0.8 mm), the effect of preventing displacement by tension control by the present sticking device is particularly remarkable.

[0019] The unwinding reel 11 has the tape 2 wound thereon, and the tape 2 is appropriately fed to the crimping portion 13 by rotation by a motor (not shown). The winding reel 16 is a reel for winding and recovering the release film 22 which is the remaining portion after the attachment portion 21 of the tape 2 is peeled off at the crimping portion 13, and winds up the release film 22 by rotation by a motor (not shown).

[0020] As illustrated in FIGS. 1 to 3, the unwinding dancer 12 and the winding dancer 15 include a balance bar 31 that can swing freely with a rotating shaft 32 supported by a bearing as a fulcrum, and a guide roller 35 that contacts the tape 2 provided at one end side end portion 33 of the balance bar 31. The balance bar 31 swings with the rotating shaft 32 as a fulcrum so that the balance between the tape 2 in contact with the guide roller 35 at one end side end portion 33 and the other end side end portion 34 is balanced, and the force in the direction in which the guide roller 35 rises is applied to the tape 2 as tension. Furthermore, a weight may be provided at the other end side end portion 34 of the balance bar 31 to balance the weights of the one end side and the guide roller 35 to adjust the balance of the balance bar 31 and perform tension adjustment. The pay - out dancer 12 and the take - up dancer 15 apply a tension of the same magnitude to the tape 2 and the release film 22 which is the remaining part after the attachment portion 21 has peeled off. The "tension of the same magnitude" means that the difference in the magnitude of the tension applied by the pay - out dancer 12 and the take - up dancer 15 is within a range where the tape 2 and the like do not move when the gripping of the release film 22 by the chuck portion 14 is released and the tape 2 and the like become movable. This range of magnitude varies depending on the sliding resistance of the guide roller 17 on the conveyance path of the tape 2 and the like and the sliding resistance of the rotation axes of the pay - out dancer 12 and the take - up dancer 15. The specific value of this range can be, for example, 1 - 10% (particularly preferably 2 - 8%) of the applied tension.

[0021] As shown in FIG. 3, the position of the rotation axis 32 of the balance bar 31 can be set at the center where the distances between the one - end side end portion 33 and the other - end side end portion 34 and the rotation axis 32 are equal. By setting the position of the rotation axis 32 at the center, the other - end side end portion 34 where the weight of the balance bar 31 is provided can be spaced from each of the reels 11 and 16 to the same extent as the guide roller 35. Therefore, the position for attaching the weight is far from each of the reels 11 and 16, the guide roller 35, and the tape 2, making it easy to adjust the tension of the tape 2. Incidentally, the position of the rotation axis 32 of the balance bar 31 may be at a position other than the center, but a position where the position for attaching the weight is far from each of the reels 11 and 16, the guide roller 35, and the tape 2 is preferable.

[0022] The crimping portion 13 crimps the attachment portion 21 to the attachment target 91 by pressing the attachment portion 21 of the tape 2 at the position where the attachment of the attachment target 91 is required. Such a crimping portion 13 is disposed between the guide rollers 17 that convey the tape, and includes a crimping stage 131 on which the attachment target 91 is placed and a crimping tool 132 that presses the attachment portion 21 onto the crimping stage 131.

[0023] Further, the crimping portion 13 can be provided with a cutting portion that cuts the attachment portion 21 to a predetermined length before performing the pressing. Further, the crimping portion 13 may heat the crimping tool 132 to soften and harden the attachment portion 21 simultaneously with the pressing, thereby thermocompression-bonding the attachment portion 21 to the object to be attached 91. When performing this thermocompression bonding, it is preferable that the crimping stage 131 be cooled before and after the thermocompression bonding. The means for cooling can be appropriately selected. For example, an opening can be provided on the stage surface of the crimping stage 131, and cooling can be achieved by blowing cooling air from the opening.

[0024] The chuck portion 14 includes a fixed chuck 141 and a feed chuck 142 provided in the conveyance path of the release film 22 located between the crimping portion 13 and the take-up dancer 15. The chuck portion 14 fixes the position of the tape during crimping of the crimping portion 13 by gripping the fixed chuck 141 located on the side closer to the crimping portion 13 in the conveyance path of the release film 22, and moves the position of the tape 2 so that the attachment portion 21 of the tape 2 reaches a predetermined position on the object to be attached 91 by gripping and moving the feed chuck 142 on the side closer to the take-up dancer 15 in the conveyance path.

[0025] The pasting device 1 can be provided with a locking portion 4 for locking the pasting component 92 to the opposite surface of the attachment portion 21 of the object to be attached 91 to which the attachment portion 21 is pasted. As shown in FIG. 4, the locking portion 4 includes a locking stage 41 on which the object to be attached 91 (not shown) to which the attachment portion 21 is pasted is placed, a component locking portion 43 for placing and locking the pasting component 92 (not shown) on the attachment portion 21, and a locking control portion 45 (not shown) for controlling the locking stage 41 and the component locking portion 43.

[0026] The locking stage 41 is provided with a stage camera 42 for photographing a marker of the object to be attached 91 placed on the locking stage 41 from below the placement surface (photographing from below the object to be attached 91), and is installed movably in the horizontal direction on the base 10 of the pasting device 1. Further, the component locking portion 43 is provided with a component locking portion camera 44 for photographing a marker of the object to be attached 91 placed on the locking stage 41 from above, and is disposed movably in the horizontal direction above the base 10. The base 10 is provided with a reference point marker 46 that can be photographed by the stage camera 42 and the component locking part camera 44. The reference point marker 46 is plate-shaped and includes a lower marker 461 provided on the lower surface for photographing by the stage camera 42 and an upper marker 462 provided on the upper surface for photographing by the component locking part camera 44. Also, the locking stage 41 and the component locking part 43 are arranged at positions where they do not contact each other even if they perform horizontal movement without being linked to each other in order to simultaneously photograph the reference point marker 46 by their respective cameras 42 and 44.

[0027] The locking control unit 45, under the control by a computer or the like, horizontally moves the locking stage 41 to a position where the stage camera 42 can photograph the lower marker 461 of the reference point marker 46, and then photographs the reference point marker 46 by the stage camera 42. Thereafter, the position of the photographed reference point marker 46 is analyzed to perform the horizontal position correction. Also, the locking control unit 45 horizontally moves the component locking part 43 to a position where the component locking part camera 44 can photograph the upper marker 462 of the reference point marker 46, and then photographs the reference point marker 46. Thereafter, the position of the photographed reference point marker 46 is analyzed to perform the horizontal position correction.

[0028] The object to be pasted 91 with the pasted component 92 locked by the pasting part 21 is heated and pressurized while being placed on the pressurizing stage to soften the resin of the pasting part 21, and can be electrically connected between the pasted component 92 and the object to be pasted 91 with conductive material fine particles dispersed in the pasting part 21. At this time, it is preferable that the pressurizing stage is cooled before and after the heating and pressurization. The cooling means can be appropriately selected, for example, an opening is provided on the stage surface of the pressurizing stage, and cooling can be achieved by blowing cooling air from the opening.

[0029] An example of the pasting process by the present pasting device 1 having the above configuration will be described below. In this pasting process, an ACF tape 2 with a width of 0.6 mm is pasted onto the electrodes of a liquid crystal display module 91, which is the object to be pasted. Also, as shown in FIGS. 1 and 2, the object to be pasted 91 is preliminarily placed on the crimping stage 131 of the crimping portion 13. The unwinding reel 11 and the winding reel 16 rotate as the feed chuck 142 of the chuck portion 14 moves. Also, the unwinding reel 11 unwinds a tape 2 having a length corresponding to the moving amount of the feed chuck 142.

[0030] The unwound ACF tape 2 is biased with a tension of 0.1 to 1 N by the guide roller 17 of the unwinding dancer 12 and is supplied to the crimping portion 13 via the guide roller 17. The ACF tape 2 supplied to the crimping portion 13 is cut by a cutting portion (not shown) so that the pasting portion 21 has a pasting length corresponding to the object to be pasted 91. Thereafter, the movement of the feed chuck 142 stops, and the fixed chuck 141 grips the release film 22. Next, the crimping tool 132 moves toward the crimping stage 131 side and presses the pasting portion 21 against the object to be pasted 91 from the release film 22 side of the tape 2. By this pressing, the pasting portion 21 is crimped to the object to be pasted 91. Thereafter, when the crimping tool 132 moves away from the crimping stage 131, the tape 2 separates from the object to be pasted 91, and at the same time, the pasting portion 21 peels off from the release film 22. Next, the fixed chuck 141 releases the release film 22, the release film 22 is gripped and moved by the feed chuck 142, and at the same time, the unwinding reel 11 and the winding reel 16 rotate to prepare for the next crimping and to wind the release film 22 onto the winding reel 16. Also, the release film 22 wound onto the winding reel 16 is biased with the same tension as the unwinding dancer 12 by the winding dancer 15. Due to the biasing of the tension by the unwinding dancer 12 and the winding dancer 15, the ACF tape 2 located between the unwinding reel 11 and the winding reel 16 and the release film 22 from which the pasting portion 21 has peeled are uniformly biased with a tension of 0.1 to 1 N.

[0031] When the fixed chuck 141 releases the release film 22, if the tension of the ACF tape 2 and the release film 22 from the unwind reel 11 to the fixed chuck 141 that was holding them is not substantially the same as the tension of the release film 22 from the fixed chuck 141 that was being held to the take-up reel 16, the ACF tape 2 and the release film 22 will move towards the side with the greater tension, resulting in misalignment, or there will be temporary sagging in the ACF tape, and there is a risk of misalignment in the length direction of the ACF tape 2 and the release film 22. Also, when the feed chuck 142 releases the release film 22, if the tension of the ACF tape 2 and the release film 22 from the unwind reel 11 to the feed chuck 142 that was holding them is not substantially the same as the tension of the release film 22 from the feed chuck 142 that was being held to the take-up reel 16, there is also a risk of misalignment, similar to when the fixed chuck 141 is released.

[0032] However, by providing the unwind dancer 12 and the take-up dancer 15, it is possible to apply tension to the tape 2 being unwound and the remaining release film 22 regardless of the open / closed state of the chucks 141, 142. By equalizing the tension, the front-back tension difference can be eliminated. And it is possible to suppress the deviation of the attachment position of the tape 2 caused by the tension difference and perform highly accurate attachment. In particular, the pay-out dancer 12 and the take-up dancer 15 using the balance bar 31 can easily apply a smaller tension than a dancer roller that adjusts tension by the weight of a conventional single bowl. That is, as shown in FIG. 3, the pay-out dancer 12 and the take-up dancer 15 can attach and detach a weight to the other end side end 34 away from the reels 11, 16 and the tape 2 and the remaining release film 22. Therefore, the tension adjustment work by the weight is easy, and there is no change in the tension generated when switching between idling and non-idling, such as in the case of permatorque. Further, by setting the length of the bowls at the one end side end 33 and the other end side end 34 to be longer than the radius of a constant reel, the moment by the weight can be increased, and the tension can be easily adjusted. Furthermore, by setting the axis of the balance bar 31 on the same axis as the axes of the reels 11, 16, there is no change in the distance between the guide roller 17 and the axes of the reels 11, 16 due to the swing of the balance bar 31, and there is no change in the tension. Therefore, even with a tension of about 0.1 N to 1 N, the displacement in the length direction of the ACF tape 2 due to the operation of the chuck portion 14 can be kept within 50 μm (preferably within 30 μm), and the accuracy of the attachment position can be maintained with high precision.

[0033] The attachment target 91 to which the attachment portion 21 is attached is subsequently placed on the locking stage 41 of the locking portion 4, and the attachment component 92 is locked. The locking portion 4 performs position calibration of the locking stage 41 and the component locking portion 43 shown in FIG. 4 by the reference point marker 46 by the locking control portion 45, and then photographs markers provided on the attachment target 91 and the attachment component 92 (both not shown) by the stage camera 42 and the component locking portion camera 44 to perform position detection, and corrects the positions at the time of locking of the locking stage 41 and the component locking portion 43 according to the exposed positions. Next, the component locking portion 43 approaches the locking stage 41 and presses the attachment component 92 against the attachment portion 21 of the attachment target 91 to lock the attachment component 92 to the attachment target 91. Thereafter, the component locking portion 43 separates from the locking stage 41 to complete the locking. Such a locking portion 4 calibrates the positions of the locking stage 41 and the component locking portion 43 by the reference point marker 46 before each locking step, so that it is possible to eliminate the accumulation of mechanical misalignment and misalignment due to temperature changes or the like.

[0034] Furthermore, in the present invention, the invention is not limited to the embodiments shown above, and various modified embodiments can be adopted within the scope of the present invention according to the purpose and application.
