Description

  The present invention includes an adhesive tape supply device that attaches a backing to one side of an anisotropic conductive sheet and supplies an adhesive tape from which the adhesive surface of the anisotropic conductive sheet is exposed from one side, and an adhesive supplied from this device. The present invention relates to an adhesive tape attaching apparatus and an attaching method for attaching a tape to an article and peeling a mount.

  For example, an anisotropic conductive sheet is used in the manufacturing process of a liquid crystal display. The anisotropic conductive sheet is a pressure-sensitive adhesive tape that is composed of a conductive layer having adhesiveness, a mount is attached to one side, and the pressure-sensitive adhesive surface of the anisotropic conductive sheet is exposed from one side. The pressure-sensitive adhesive tape is wound around a supply reel constituting the pressure-sensitive adhesive tape supply device and is fed out as it is.

  The adhesive tape is guided by a plurality of guide rollers constituting the tape guiding means, and a predetermined tension is applied by the tension roller, thereby preventing displacement due to meandering and undulation. The pressure-sensitive adhesive tape is led out from the pressure-sensitive adhesive tape supply device and guided to the pressure-sensitive adhesive tape applying device.

  In the adhesive tape sticking device, a substrate constituting liquid crystal is placed on a table, and the adhesive tape supplied from the adhesive tape supply device is guided onto the substrate. Here, the affixing means acts to affix the anisotropic conductive sheet to the electrode of the substrate, and then peels off the backing sheet to expose the adhesive layer of the anisotropic conductive sheet and affix the electrode of the tab component.

  In [Patent Document 1], the pressure-sensitive adhesive tape can be fed out with a constant tension regardless of the diameter of the roll for supplying the pressure-sensitive adhesive tape or the strength of the pressure-sensitive adhesive force of the pressure-sensitive adhesive tape, and the apparatus is enlarged. There is also disclosed an adhesive tape feeding device that hardly contaminates the adhesive surface and an adhesive tape attaching device using the same.

Japanese Patent Laid-Open No. 2002-20028

  However, in the technique of [Patent Document 1], it is necessary to provide a motor which is a drive source dedicated to the drive roller, and a friction joint is provided for applying a predetermined tension to the supply reel via the drive roller. As a result, since the friction joint applies tension, the motor must have a large driving force, and the apparatus becomes larger and the running cost increases.

  A general adhesive tape supply apparatus guides an adhesive tape fed from a supply reel with a plurality of guide rollers. In the middle, a tension roller is provided to which one end of the spring is hooked, and a predetermined tension is applied to the adhesive tape. Such an apparatus can be provided at a low price, and the running cost can be reduced by avoiding the enlargement of the apparatus.

  Even in this type of apparatus, the mounting side of the adhesive tape is brought into contact with the guide roller and the tension roller as much as possible so as not to contact the adhesive surface of the anisotropic conductive sheet. When the guide surface of the roller comes into contact with the adhesive surface, a part of the conductive layer constituting the anisotropic conductive sheet peels off and adheres to the roller, or contamination (dust) adheres from the roller to the adhesive surface. Contaminated.

  However, no matter how the guide path is taken, at least one guide roller or tension roller always rolls on the adhesive surface of the anisotropic conductive sheet. Although a so-called Adlon coating process is performed on the guide surface of the roller, and the above-described means for partially removing the conductive layer and reducing the contamination of the adhesive surface is employed, it is not perfect.

  The present invention has been made on the basis of the above circumstances, and the purpose thereof is to partially peel off the conductive layer, even if it is configured to contact and guide the anisotropic conductive sheet adhesive surface of the adhesive tape, It is an object of the present invention to provide an adhesive tape supply device capable of reliably preventing contamination of the adhesive surface and improving reliability, and an adhesive tape attaching device and an attaching method using the device.

  In order to satisfy the above object, the pressure-sensitive adhesive tape supply device of the present invention sequentially attaches a backing sheet to one side of an adhesive anisotropic conductive sheet, and sequentially applies the pressure-sensitive adhesive tape on which the pressure-sensitive adhesive surface of the anisotropic conductive sheet is exposed on one side. A feeding means for feeding out and a tape guiding means composed of a plurality of guide bodies for moving and guiding the adhesive tape fed out from the feeding means, wherein at least one guide body in the tape guiding means is made of a porous material; At the same time, high-pressure air is ejected from the guide surface of the guide body, and the guide surface is guided in a non-contact state with respect to the adhesive surface of the anisotropic conductive sheet constituting the adhesive tape.

  In order to satisfy the above object, the pressure-sensitive adhesive tape bonding apparatus of the present invention is a bonding means for bonding a pressure-sensitive adhesive tape supplied using the pressure-sensitive adhesive tape supply device to an article, and an anisotropic conductive sheet from a bonding portion by the bonding means. And a peeling means for peeling off the mount.

  In order to satisfy the above object, the pressure-sensitive adhesive tape application method of the present invention applies the pressure-sensitive adhesive tape supplied using the pressure-sensitive adhesive tape supply device to an article, and peels the mount leaving an anisotropic conductive sheet from the application portion.

  According to the present invention, even if it is configured to contact and guide the anisotropic conductive sheet adhesive surface exposed by the adhesive tape, it is possible to reliably prevent partial peeling of the conductive layer and contamination of the adhesive surface, and reliability. The effect which can aim at improvement of is produced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 6, for example, a plurality of electrodes 2 are provided outside the display area on the surface of the substrate 1 constituting the liquid crystal, and supplied from an adhesive tape supply device 10 described later on the electrodes 2. The anisotropic conductive sheet 3 is attached by an adhesive tape attaching device 50.

  A mount 4 is affixed to one side surface of the anisotropic conductive sheet 3, and the adhesive tape 5 is constituted by these. The pressure-sensitive adhesive surface made of the conductive layer of the anisotropic conductive sheet 3 exposed from the pressure-sensitive adhesive tape 5 is adhered to the electrode 2, and the mount 4 is then peeled from the anisotropic conductive sheet 3. Therefore, the adhesive surface a of the anisotropic conductive sheet that has been covered by the mount 4 until then is exposed.

  Next, the tab component 7 on which the electronic component 6 is mounted and a predetermined wiring pattern is formed is superimposed on the newly exposed adhesive surface a of the anisotropic conductive sheet 3. In this state, a constant pressure is applied so that the electrode 2 on the substrate 1 and the electrode 8 on the tab component 7 side are electrically connected via the anisotropic conductive sheet 3.

FIG. 1 is a schematic configuration diagram of an adhesive tape pasting device 50 provided with the adhesive tape supply device (enclosed by a one-dot chain line) 10 as a first embodiment. (Note that components not marked in the text are not shown. The same applies hereinafter.)
As the adhesive tape supply device 10, a supply reel 11, which is a supply mechanism (delivery means) around which the adhesive tape 5 is wound, is provided. The pressure-sensitive adhesive tape 5 includes a mount 4 (shown by a solid line) and an anisotropic conductive sheet (shown by a broken line) 3 in which the mount 4 is bonded and covered on one side, and the pressure-sensitive adhesive surface a is exposed on one side. It consists of.

  In a state where the adhesive tape 5 is wound around the supply reel 11, the adhesive surface a of the anisotropic conductive sheet 3 is on the side of the axis b of the supply reel 11 which is on the inside, and the mount 4 is on the outside. Accordingly, the adhesive surface a of the anisotropic conductive sheet 3 of the outer peripheral side adhesive tape 5 is in close contact with the mount 4 of the inner peripheral side adhesive tape 5, but when the anisotropic conductive sheet 3 is drawn out from the supply reel 11, The adhesive surface a is easily separated from the mount 4 and does not have any trouble in feeding.

  A guide mechanism (tape guide means) G composed of a plurality of guide rollers (guide bodies) 12 to 14 and a single tension roller 15 is provided on the feeding reel 11 on the adhesive tape 5 feeding side. Here, the adhesive tape 5 is fed out from the feeding reel 11 in a substantially horizontal direction, and a first guide roller 12 is provided in the feeding direction.

  The first guide roller 12 has a smooth surface in which the shaft core portion c is rotatably supported by a bearing member and the peripheral surface is not subjected to any processing. The length of the first guide roller 12 in the axial direction is slightly longer than the length of the adhesive tape 5 in the width direction, and flanges protrude from both sides to ensure that the adhesive tape 5 has sufficient dimensions. Can guide you.

  The first guide roller 12 guides the adhesive tape 5 in the vertical direction, and a tension roller 15 is provided in this guide direction. In the tension roller 15, one end portion of the spring 16 is hooked on the shaft core portion d, and a constant tensile force is always acting in the downward direction. Similar to the first guide roller 12, the axial length of the guide portion, the peripheral surface shape, and the flange portion projecting on both sides are provided.

  A second guide roller 13 described later is provided immediately above the tension roller 15. The adhesive tape 5 guided in a substantially U shape from the first guide roller 12 through the tension roller 15 to the second guide roller 13 is given a constant tension by the tension roller 15. Therefore, the adhesive tape 5 is guided to move through the adhesive tape supply device 10 without sagging or meandering.

  A third guide roller 14 is provided immediately below the second guide roller 13 to guide the adhesive tape 5 guided from the second guide roller 13 in a substantially horizontal direction. These constitute the adhesive tape supply device 10, and the adhesive tape 5 extends horizontally from the third guide roller 14 and is supplied to the adhesive tape affixing device 50.

  The second guide roller 13 is configured as shown in FIGS. 2A is a front view of the second guide roller 13, and FIG. 2B is a cross-sectional view of the second guide roller 13.

  The second guide roller 13 includes a guide portion 20 having a predetermined diameter and slightly longer than the length in the width direction of the adhesive tape 5 at a substantially central portion in the axial direction length. On both sides in the axial direction of the guide portion 20, flange portions 21 that protrude from the guide surface 20 a that is the circumferential surface of the guide portion 20 to a height that is at least larger than the thickness dimension of the adhesive tape 5 are integrally provided.

  Boss portions 22 are provided on both side surfaces of the both flange portions 21, and these boss portions 23 are attached and fixed to a support. That is, since the second guide roller 13 does not need to rotate as will be described later, the supporter fixedly supports the second guide roller 13, but the second guide roller 13 is rotatably supported. Of course, it is also good.

  A joint 23 projects from the side surface of one boss 22, and a high-pressure pipe P indicated by a solid line in FIG. The high-pressure pipe P is provided with a filter 24, and a high-pressure air pump 25 is connected through the filter 24. When the high-pressure air pump 25 is driven, the external air is compressed and increased in pressure to be guided to the filter 24 and further to the second guide roller 13.

  As shown in FIG. 2 again, the second guide roller 13 is provided with an air introduction hole 26 communicating with the joint 23. The air introduction hole 26 is provided along the axial center from the side surface of the boss portion 22 where the joint 23 is provided to the vicinity of the side surface of the boss portion 22 where the other joint 23 is not provided. The air introduction hole 26 must not be provided so as to open from the side surface of the other boss portion 22.

  The guide portion 20 is provided with air ejection holes 27 in a plurality of rows (here, three rows) along the axial direction at a predetermined angle. All of the air ejection holes 27 are provided so as to penetrate from a predetermined part of the guide surface 20a to a part of the guide surface 20a opposed to 180 ° through the air introduction hole 26.

  Actually, since the adhesive tape 5 is guided by the upper half guide surface 20a of the second guide roller 13 as shown in FIG. 1, the air ejection holes 27 should be opened only in the upper half of the guide surface 20a. That's fine. However, in terms of manufacturing, if the structure penetrates from the guide surface 20a to the portion of the guide surface 20a opposed by 180 ° via the air introduction hole 26 in the shaft core, the processing is easier than the halfway processing.

  As a result, on the guide surface 20a of the second guide roller 13, a large number of air ejection holes 27 communicating with the air introduction holes 26 provided in the shaft core are opened. Therefore, the second guide roller 13 itself may be replaced with a so-called porous material.

  In the adhesive tape attaching device 50, a cutter 51 as a cutting mechanism and an attaching roller 52 as an attaching mechanism (attaching means) are attached to the adhesive tape 5 at a position where the adhesive tape supply device 10 is unloaded from the third guide roller 14. Are arranged side by side along the moving direction. A table T on which the substrate 1 is placed is arranged in the carry-out direction of the third guide roller 14.

  The cutter 51 is provided to be movable up and down with the blade portion e facing upward. When the cutter 51 is driven up to a predetermined position, the blade portion e is anisotropically conductive, leaving the mount 4 of the adhesive tape 5 spanned between the third guide roller 14 and the affixing roller 52. It is configured to cut only the sheet 3.

  The affixing roller 52 is positioned so as to be in rolling contact with the adhesive tape 5 carried out from the adhesive tape supply device 10. Then, while maintaining the state of rolling contact with the adhesive tape 5, it is in close contact with the substrate 1 on the table T and is driven to reciprocate along the substrate 1.

  In the vicinity of the table T, a substrate supply device and a tab component supply device are arranged to face each other, and the substrate 1 is supplied and placed on the table T as described above with reference to FIG. In addition, the tab component 7 is supplied to the substrate 1.

  Further, the adhesive tape attaching device 50 includes a peeling mechanism (peeling means) 53 and a collection reel 54 that is a collection unit. The peeling mechanism 53 includes a pair of upper and lower peeling rollers 55 and 56 and a box body 57 that rotatably supports these rollers. The box body 57 is located above the table T, and is driven to reciprocate from one end of the table T to the other end while accommodating the peeling rollers 55 and 56.

  Only the upper-side peeling roller 56 has the same form as the second guide roller 13 described above with reference to FIGS. That is, it has a joint connected to a high-pressure pipe branched from the high-pressure pipe P where the high-pressure air pump 25 and the filter 24 are provided, a flange part and a guide part are provided on the peripheral surface, and an air introduction hole communicating with the joint, A large number of air ejection holes communicate with the air introduction hole and are opened in the guide surface which is the circumferential surface of the guide portion.

  The collection reel 54 is rotationally driven at the position shown in the drawing, and takes up and collects the adhesive tape 5 guided from the adhesive tape supply device 10 to the adhesive tape attaching device 50. Not only that, but depending on the position of the peeling mechanism 53 as will be described later, the adhesive tape 5 that has been wound up is delivered as necessary.

The adhesive tape supply apparatus 10 and the adhesive tape sticking apparatus 50 are comprised as mentioned above.
As described above, the adhesive tape 5 in the supply reel 11 of the adhesive tape supply device 10 is wound so that the adhesive surface a of the anisotropic conductive sheet 3 is on the supply reel shaft core b side, and the mount 4 is on the outer side. It is disguised. The adhesive tape 5 faces the adhesive surface a of the anisotropic conductive sheet (dotted line) 3 upward and the mount (solid line) 4 downwards with respect to the first guide roller 12 provided on the side portion of the delivery reel 11. Served in an exposed state.

  Since the tension roller 15 is disposed below the first guide roller 12, the adhesive tape 5 is guided so that the mount 4 contacts the first guide roller 12. The adhesive tape 5 is guided from the first guide roller 12 as it is so that the mount 4 contacts the tension roller 15.

  The second guide roller 13 is provided above the tension roller 15, and the third guide roller 14 is provided below the second guide roller 13. That is, the adhesive tape 5 guided in the U-turn shape upward by the tension roller 15 is guided in the reverse U-turn shape downward by the second guide roller 13.

  In the tension roller 15, the adhesive tape 5 is guided so that the mount 4 comes into contact, but in the second guide roller 13, the adhesive tape 5 is guided so that the adhesive surface a of the anisotropic conductive sheet 3 comes into contact therewith. In the third guide roller 14, the adhesive tape 5 is guided so that the mount 4 comes into contact.

  In the adhesive tape pasting device 50, the blade portion e of the cutter 51 serving as a cutting mechanism is provided to face the anisotropic conductive sheet adhesive surface a of the adhesive tape 5, and the pasting roller 52 contacts the adhesive tape mount 4. To be provided. That is, the anisotropic conductive sheet adhesive surface a of the adhesive tape 5 faces the substrate 1 on the table T.

  In the peeling mechanism 53, the pressure-sensitive adhesive tape 5 is first guided by the lower-side peeling roller 55. The pressure-sensitive adhesive tape mount 4 comes into contact with the lower-side peeling roller 55, and the guided upper-side peeling roller 56 is then guided. Is in contact with the adhesive surface a of the anisotropic conductive sheet. The collection reel 54 is wound so that the mount 4 is on the inner core f side of the collection reel 54 and the anisotropic conductive sheet adhesive surface a is on the outside.

  In this manner, the adhesive tape 5 is guided from the adhesive tape supply device 10 to the adhesive tape applying device 50. In particular, when the adhesive tape 5 is guided to the first guide roller 12 and the tension roller 15 in the adhesive tape supply device 10, there is no problem because the mount 4 comes into contact with the rollers 12 and 16.

  However, the adhesive tape 5 is guided by the second guide roller 13 so that the exposed adhesive surface a of the anisotropic conductive sheet 3 is in contact. At the same time, the high-pressure air pump 25 is driven, and clean high-pressure air filtered through the filter 24 is supplied to the second guide roller 13.

  Clean high-pressure air is guided from the air introduction holes 26 in the second guide roller 13 to a large number of air ejection holes 27, and is ejected from the guide surface 20 a that is the peripheral surface of the guide portion 20. On the other hand, since the anisotropic conductive sheet adhesive surface a faces the guide surface 20a, high-pressure air is sprayed from the air ejection holes 27 to the anisotropic conductive sheet adhesive surface a. The pressure-sensitive adhesive tape 5 is lifted from the guide surface 20a of the second guide roller 13 upon receiving high-pressure air.

  Eventually, the adhesive surface a of the anisotropic conductive sheet 3 is guided by the guide roller 13 without contacting the guide surface 20a of the second guide roller 13. Therefore, a part of the conductive layer constituting the anisotropic conductive sheet 3 is peeled off and transferred to the guide surface 20a, and the guide surface is contaminated or dust adhered to the guide surface 20a is adhered to the anisotropic conductive sheet. There is no transfer to the surface a and the adhesive surface a is not contaminated.

  Since the mount 4 of the adhesive tape 5 comes into contact with the third guide roller 14, there is no problem. The pressure-sensitive adhesive tape 5 led out from the pressure-sensitive adhesive tape supply device 10 to the pressure-sensitive adhesive tape pasting device 50 is temporarily stopped, the cutter 51 is raised at a timing, and only the anisotropic conductive sheet 3 is cut. wear.

  The movement of the adhesive tape 5 is started again, and the movement of the adhesive tape 5 is stopped when the adhesive tape 5 is moved by the length of the substrate 1 from the cut portion by the cutter 51. The cutter 51 is operated again and only the anisotropic conductive sheet 3 is operated. Make a cut in The adhesive tape 5 is stopped moving at the timing when the first cut reaches the one end of the substrate 1. Then, the affixing roller 52 contacts the mount 4 of the adhesive tape 5 and presses the adhesive tape 5 against the substrate 1 on the table T.

  As shown by the solid line arrow in FIG. 1, the sticking roller 52 moves (moves forward) from one end of the substrate 1 along the other end, and sticks to the anisotropic conductive sheet 3 that has been exposed to the lower surface until then. Surface a is affixed to substrate 1. That is, as described above with reference to FIG. 6, the anisotropic conductive sheet 3 is attached to the electrode 2 of the substrate 1, but at this point, the mount 4 is left as it is.

  As shown by a two-dot chain line in FIG. 1, when the affixing roller 52 reaches the other end of the substrate 1 and the anisotropic conductive sheet 3 is affixed over the entire length of the substrate 1, this is indicated by a two-dot chain line arrow. As shown, the application roller 52 returns to one end of the substrate 1. The height position of the sticking roller 52 is not changed at all, and therefore moves (returns) so as to come into contact with the substrate 1.

  Simultaneously with the backward movement of the affixing roller 52, the peeling mechanism 53 moves in the direction of the two-dot chain line in the figure at the same speed. Therefore, the affixing roller 52 and the peeling mechanism 53 move while the mutual positional relationship between the affixing roller 52 and the peeling mechanism 53 is not changed at all, and the mount 4 is partially wound around the peeling rollers 55 and 56. .

  By these actions, the adhesive tape 5 leaves the anisotropic conductive sheet 3 attached to the electrode 2 of the substrate 1, and the mount 4 is peeled from the anisotropic conductive sheet 3. As the mount 4 is peeled off, the adhesive surface a of the anisotropic conductive sheet 3 that has been covered by the mount 4 is exposed.

  When the affixing roller 52 moves back to the original solid line position shown in FIG. 1, the movement of the affixing roller 52 and the peeling mechanism 53 stops. At this timing, the tab component 7 is supplied from the tab component supply device onto the substrate 1, and the electrode 8 of the tab component 7 is attached to the adhesive surface a of the anisotropic conductive sheet 3 that is newly exposed. Therefore, the substrate 1 and the tab component 7 are electrically connected via the anisotropic conductive sheet 3.

  Next, the substrate 1 on the table T is taken out and a new substrate 1 is placed on the table T. Thereafter, the peeling mechanism 53 moves to the original position, the supply of the adhesive tape 5 in the adhesive tape supply device 10 is resumed again as described above, and the anisotropic conductive sheet 3 is attached to the substrate 1.

  The adhesive tape 5 that is the mount 4 after being peeled off from the anisotropic conductive sheet 3 by the peeling mechanism 53 is taken up as the collection reel 54 is driven to rotate. When the peeling mechanism 53 moves in the direction of the two-dot chain line in FIG. 1, the adhesive tape 5 that has been wound around the collection reel 54 is fed out. Therefore, it is possible to prevent the adhesive tape 5 from sagging between the recovery reel 54 and the peeling mechanism 53.

  In other words, after the affixing roller 52 has affixed the anisotropic conductive sheet 3 to the substrate 1, the adhesive tape 5 is slightly guided to the peeling mechanism 53 with a part of the anisotropic conductive sheet 3 remaining. It is burned. Specifically, the adhesive tape 5 contacts the lower side peeling roller 55 of the peeling mechanism 53 and then contacts the upper side peeling roller 56.

  At this time, since the mount 4 comes into contact with the lower-side peeling roller 55 from the arrangement configuration of the peeling mechanism 53, there is no problem. Further, since the remaining adhesive surface a of the anisotropic conductive sheet 4 is in contact with the upper-side peeling roller 56, as it is, peeling of a part of the conductive layer of the anisotropic conductive sheet 3 or the upper-side peeling roller 56 guide surface Problems such as dirt will occur.

  However, the upper-side peeling roller 56 has the same configuration as the second guide roller 13, and high-pressure air is ejected from the guide surface, and the adhesive tape 5 is guided in a floating state without contacting the guide surface. Therefore, problems such as separation of a part of the conductive layer of the anisotropic conductive sheet 3 and contamination of the guide surface of the upper-side peeling roller 56 do not occur.

  FIG. 3 is a partial schematic configuration diagram of the guide mechanism GA in the adhesive tape supply device 10 as the second embodiment, and FIG. 4 is an outline of the peeling mechanism 53A in the adhesive tape affixing device 50 as the embodiment. It is a block diagram.

  First, referring to FIG. 3, the second guide roller 13A provided between the tension roller 15 and the third guide roller 14 has a normal structure in which no processing is applied to the guide portion. . However, the second guide roller 13A is covered with a cleaning sheet 60, and the cleaning sheet 60 is between the anisotropic conductive sheet adhesive surface a of the adhesive tape 5 and the guide surface of the second guide roller 13A. Intervene in.

  As it is, the second guide roller 13A is in contact with the anisotropic conductive sheet adhesive surface a of the adhesive tape 5, but the cleaning sheet 60 is interposed between the guide roller 13A and the adhesive surface a. Therefore, it is ensured that a part of the conductive layer of the anisotropic conductive sheet 3 is peeled off and transferred to the second guide roller 13A, or dust adhered to the roller guide surface is transferred to the anisotropic conductive sheet 3. To prevent.

  The cleaning sheets 60 are sequentially fed out from the sheet supply unit 60A every predetermined period, and the fed out cleaning sheets 60 are sequentially collected by the collection unit 60B. Avoiding wear of the cleaning sheet 60, a new cleaning sheet 60 portion is always interposed between the guide roller 13A and the anisotropic conductive sheet pressure-sensitive adhesive surface a, and the above-described effects can be reliably maintained.

  Next, FIG. 4 will be described. In the peeling mechanism 53A, the lower side peeling roller 55 and the upper side peeling roller 56A are of a normal structure that is not subjected to any processing. However, the upper side peeling roller 56A is covered with the cleaning sheet 60, and the cleaning sheet 60 is interposed between the anisotropic conductive sheet pressure-sensitive adhesive surface a of the pressure-sensitive adhesive tape 5 and the upper side peeling roller 56A.

  As it is, the upper peeling roller 56A is in contact with the anisotropic conductive sheet pressure-sensitive adhesive surface a of the pressure-sensitive adhesive tape 5, but the cleaning sheet 60 is interposed between the peeling roller 56A and the pressure-sensitive adhesive surface a. In addition, a part of the conductive layer of the anisotropic conductive sheet 3 is peeled off and transferred to the peeling roller 56A, and dust attached to the peeling roller 56A is reliably prevented from transferring to the anisotropic conductive sheet 3.

  The cleaning sheets 60 are sequentially fed out from the sheet supply unit 60A every predetermined period, and the fed out cleaning sheets are sequentially collected in the collecting unit 60B. Avoiding wear of the cleaning sheet 60, a new cleaning sheet 60 portion is always interposed between the upper-side peeling roller 56A and the anisotropic conductive sheet pressure-sensitive adhesive surface a, so that the above-described effects can be reliably maintained.

  FIG. 5 is a schematic configuration diagram of the adhesive tape supply device 10 and the adhesive tape attaching device 50 as a third embodiment. In the adhesive tape pasting apparatus 50, since there is no change from the structure previously demonstrated in FIG. 1, about the same component, the same number is attached | subjected and new description is abbreviate | omitted.

  In the adhesive tape supply device 10, the supply reel 11 constituting the supply mechanism is the same as that described above, and the adhesive tape 5 is similarly wound and fed out.

  The first guide roller 12, the second guide roller 13A, and the third guide roller 14 that constitute the guide mechanism (guide means) GB are of a normal configuration that is not subjected to any processing.

  Each guide roller 12, 13A, 14 is arranged so that the mount 4 of the adhesive tape 5 is in contact with it, and in particular, the second guide roller 13A and the third guide roller 14 have the same height with a predetermined interval. Is in position.

  Between the second guide roller 13A and the third guide roller 14, an air spray body 30 and a guide container 35 constituting the guide mechanism GB are provided. The air spray body 30 is inserted between the second guide roller 13A and the third guide roller 14 from the lower side, and the upper end is opened at a position higher than the guide rollers 13A and 14.

  A high-pressure pipe P is connected to the base end portion of the air spray body 30, and the high-pressure air pump is provided in the high-pressure pipe P through the filter. The guide container 35 is a cylindrical body whose lower end is opened and whose upper end is closed, and a plurality of escape holes g are provided on the peripheral surface of the upper end. The guide container 35 surrounds the air blowing body 30 protruding upward from between the second and third guide rollers 13A and 14.

  Thus, after the adhesive tape 5 fed out from the supply reel 11 is guided in a state where the mount is in contact with the first guide roller 12 and the second guide roller 13A, before being guided by the third guide roller 14. Then, the air is blown up by the high-pressure air ejected from the air spray body 30. For this reason, the adhesive tape 5 is in a tension state with respect to the second guide roller 13A and the third guide roller 14.

  That is, the air spray body 30 functions as a substitute for the tension roller 15 described in the first embodiment. The air spray body 30 sprays clean high-pressure air onto the anisotropic conductive sheet pressure-sensitive adhesive surface a of the adhesive tape 5 and does not directly contact, so that a part of the conductive layer of the anisotropic conductive sheet 3 is peeled off, Dust does not adhere to the adhesive surface a.

  By providing the guide container 35, the high-pressure air sprayed on the adhesive tape 5 from the escape hole g of the guide container 35 can be efficiently discharged, and the adhesive tape 5 can be reliably jetted up. Since the adhesive tape 5 is jetted up in the guide container 35, the posture change such as the meandering of the adhesive tape is prevented, and stable jetting is enabled.
