Description

  The present invention relates to an apparatus and method for forming a cut in an adhesive tape member conveyed with a release paper, an apparatus and method for peeling a part of the tape member, and a tape member attaching apparatus and method, in particular. The present invention relates to cut formation and partial peeling of anisotropic conductive tape, and adhesion to a substrate.

  In recent years, in order to attach electronic components such as TCP (Tape Carrier Package) to a substrate such as an LCD, an anisotropic conductive film (hereinafter referred to as “ACF”) has been previously used as an adhesive material. Affixed to the part.

  Now, an example of attaching ACF to a substrate will be described. ACF is attached as follows.

  First, ACF is supplied in a state of being attached to a tape-shaped release paper. Hereinafter, the release paper and the ACF that is a tape member integrated with the release paper will be referred to as an ACF tape. The ACF tape is supplied using a chuck mechanism. The ACF tape held by the chuck mechanism is pulled out from the supply unit by a predetermined length. Then, the cutting blade (half cutter) leaves the release paper to form a cut, whereby only the ACF is cut to form an ACF piece having a predetermined length. The ACF pieces formed in this manner are sequentially positioned on the substrate positioned at the attaching position, and are attached to the substrate by being pressed against the substrate through the release paper by a pressure bonding tool. Thereafter, the release paper is peeled off from the attached ACF piece by a release paper peeling device.

Moreover, in such a sticking process, when the ACF is pressed by the crimping tool, the crimping tool may press a part of the subsequent ACF in addition to the ACF piece to be pasted this time. Therefore, in order to avoid this problem, an ACF cut piece is formed by making two cuts, for example, about 5 mm apart, between the ACF piece to be pasted this time and the subsequent ACF, and peeling off the ACF cut piece. It has also been devised that a gap is formed between ACF pieces by peeling off from the release paper with a peeling device using a tape or the like.

  In the conventional apparatus and method, when the ACF has high adhesiveness, the entire ACF tape is pulled by the half cutter when the half cutter is pressed after the half cutter is pressed against the ACF and then cut. , Slack occurs in the ACF tape.

  Similarly, after the release tape is pressed against the ACF cut piece, when the release tape is pulled away, the entire ACF tape is pulled by the release tape, so that the ACF tape is loosened.

  The slack generated in this way is temporarily eliminated at the time of the next drawing of the ACF tape by the chuck mechanism, but a large impact is applied to the ACF tape at the moment when the slack is eliminated. In other words, the ACF tape is usually applied with a pulling force opposite to the conveying direction, but when the above-described loosening is eliminated, this pulling force is added to the conveying force by the chuck mechanism. is there. When a large impact force is applied to the ACF tape at the time of removing the slack in this way, the half-cut portion is particularly weak and this portion is extended, and an error occurs in the next feed amount of the ACF tape by the chuck mechanism. Become. As a result, there is a problem that the accuracy of the ACF attachment position decreases.

Motor driving unit 521 for driving 511, motor driving unit 523 for driving take-up reel driving motor 513, motor driving unit 525 for driving drawer clamper moving motor 515, and motor driving for driving peeling tape winding motor 517 Part 527, (4) drawer clamper opening / closing air cylinder 531, half-cutter vertical movement air cylinder 535, peeling head vertical movement air cylinder 537, pressure bonding head air cylinder 539, and (5) drawer clamper opening / closing air cylinder 531. Cylinder drive unit 541, half cutter vertical movement A cylinder driving unit 545 for driving the air cylinder 535, a cylinder driving unit 547 for driving the air cylinder 537 for vertical movement of the peeling head, a cylinder driving unit 549 for driving the pressure cylinder air cylinder 539, and (6) a supply unit upper limit position sensor. 551, a supply unit lower limit position sensor 553, a take-up unit upper limit position sensor 555, a take-up unit lower limit position sensor 557, and (7) a suction block electromagnetic switching valve 561.

  The half cutter 101 cuts only the ACF 121 of the ACF tape 125 including the release paper 123 and the ACF 121 which is a tape member integrated with the release paper 123.

  The ACF tape peeling unit 103 presses the peeling head 133 around which the peeling tape 131 is wound against the ACF 121 of the ACF tape 125, and then lowers the peeling tape 131 and the peeling head 133, thereby moving the two pieces inserted by the half cutter 101. The ACF cut piece 603 (see FIG. 6) between the cuts is peeled from the release paper 123. The ACF tape peeling portion 103 is provided with a tape press 135. The upper surface of the tape press 135 is positioned in the vicinity thereof so as to face the lower surface of the ACF tape 125 positioned in the supply path, and the central portion thereof is set as a path in which the peeling head 133 moves up and down. When the peeling head 133 is positioned at the rising end, the top surface of the peeling head 133 is positioned so as to protrude from the tape press 135, and when it is positioned at the descending end, the top surface is positioned below the top surface of the tape pressing 135. . Accordingly, when the peeling head 133 is lowered, the ACF tape 125 that is attached to the peeling tape 131 and is going to be lowered together with the peeling head 133 comes into contact with the upper surface of the tape press 135 so that the subsequent lowering is prevented. The peeling of the ACF cut piece 603 from the release paper 123 is assisted.

  The suction unit 105 includes a suction block 151 provided with a suction path 153, a vacuum source (not shown), and an electromagnetic switching valve 561. The suction unit 105 is disposed at a position facing the half cutter 101 and the ACF tape peeling unit 103 with the ACF tape 125 interposed therebetween. One of the suction paths 153 is opened at a surface facing the release paper 123, and the other of the suction paths 153 is connected to a vacuum source via an electromagnetic switching valve 561. Further, as will be described later, the suction part 105 descends when the ACF piece 601 (see FIG. 6) is attached to the glass substrate 81.

  The ACF tape drawer 109 has a drawer clamper 191. The drawer clamper 191 is supported by a ball screw mechanism (not shown) driven by a drawer clamper moving motor 515 so as to be capable of reciprocating in the drawing direction. The drawer clamper 191 is opened / closed by a drawer clamper opening / closing air cylinder 531.

  The ACF crimping section 106 has a thermocompression bonding tool 93 that moves up and down. Then, by the downward movement of the crimping tool 93, the ACF piece 601 in the ACF tape 125 is pressed against the glass substrate 81 through the release paper 123 and adhered. The ACF pressing unit 106 is provided with a release paper peeling device (not shown). The release paper peeling apparatus itself is known, and peels the release paper 123 from the ACF piece 601 stuck on the glass substrate 81, but the release paper stuck on the ACF piece 601 stuck on the glass substrate 81. For example, a roller-shaped or bar-shaped peeling member that moves along the longitudinal direction of the ACF piece 601 while lifting the pattern paper 123 is provided. In FIG. 5, reference numeral 533 denotes the peeling member moving air cylinder, and 543 denotes a cylinder driving unit that drives the peeling member moving air cylinder 533.

  The ACF tape supply unit 107 includes an ACF tape supply reel 171 and a first dancer roller 173.

  The ACF tape take-up unit 111 has an ACF tape take-up reel 113 and a second dancer roller 115.

  Since the configurations and operations of the first and second dancer rollers are substantially the same, only the first dancer roller 173 will be described in order to avoid redundant description.

  As shown in FIGS. 3 and 4, the first dancer roller 173 is rotatably supported by the support block 174. The support block 174 is supported by the guide portion 175 so as to be movable in the vertical direction. A wire (not shown) is connected to the upper end of the support block 174. The other end of the wire is connected to a weight 176 via a pulley (not shown) disposed near the upper end of the guide portion 175. As shown in FIG. 3, when the dancer roller 173 is at the upper limit position, the weight 176 is at the lower limit position, and as shown in FIG. 4, the wire 176 is at the upper limit position when the dancer roller 173 is in the lower limit position. Set the length so that

  Corresponding to the upper limit position and the lower limit position of the up / down stroke of the dancer roller 173, a supply unit upper limit position sensor 551 that detects that the dancer roller 173 has reached the upper limit position, and that the dancer roller 173 has reached the lower limit position. Supply unit side lower limit position sensors 553 to be detected are respectively arranged. The tape supply reel 171 is controlled based on the output values of these sensors 551 and 553. Specifically, the sensors 551 and 553 are configured by, for example, a sensor dog fixed to the support block 174 of the dancer roller 173 and a transmission type sensor disposed corresponding to the lower limit position and the upper limit position. When the support block 174 reaches the upper limit position or the lower limit position, the sensor dog blocks the sensor light of the corresponding sensor, and the sensor generates a detection signal.

  The tape supply reel 171 supplies the ACF tape 125 until the dancer roller 173 is positioned at the upper limit position at a timing before the drawing unit 109 starts to draw the ACF tape 125, and during the drawing of the ACF tape 125 by the drawing unit 109. Stop. Further, the tape take-up reel 113 on the tape take-up unit 111 side removes the release paper 123 after the ACF separation until the dancer roller 173 is positioned at the lower limit position at the timing before the drawing unit 109 starts to draw the ACF tape 125. The winding stops while the ACF tape 125 is being pulled out.

  Next, a series of operations for attaching the ACF with such a configuration will be described.

  Prior to the withdrawal of the ACF tape 125 by the tape withdrawal portion 109, the supply reel 171 is driven in the supply direction of the ACF tape 125 (the direction of the arrow 177 shown in FIG. 3) by the supply reel drive motor 511. The ACF tape 125 is fed out until the dancer roller 173 reaches the upper limit position.

  On the other hand, the take-up reel 113 is driven and stopped in the take-up direction (the direction of the arrow 117 shown in FIG. 1) until the dancer roller 115 reaches the lower limit position. In this state, the suction unit 105 holds the ACF tape 125 by suction.

  Next, the drawer 109 moves from the drawer standby position (FIG. 1) with the clamper 191 opened to the left by a distance corresponding to the length of the tape to be pulled to the current drawer start position (FIG. 1). Then, the clamper 191 is closed and the ACF tape 125 is chucked. After the suction of the suction block 151 is cut off, the drawer clamper 191 that chucks the ACF tape 125 moves in the drawing direction of the ACF tape 125 by a distance corresponding to a predetermined drawing length and returns to the standby position.

  When the half-cut target position on the ACF tape 125 reaches the half-cutter position by this drawing operation, the ACF tape 125 is half-cut by the half-cutter 101, and when the peel-off target position on the ACF tape 125 reaches the peel position. Then, the ACF cut piece 603 at the peeling target position is peeled off by the peeling portion 103. At the time of the half-cutting and peeling of the ACF cut piece, the suction unit 105 is operated each time to hold the ACF tape 125 by suction. Details of the half cut and partial peeling will be described later.

  When the ACF tape 125 is pulled out, the dancer roller 173 of the tape supply unit 107 is lowered by a distance that is half the length of the pulled-out tape. In addition, the dancer roller 115 of the tape take-up unit 111 is raised by a distance that is a half of the length of the drawn tape.

  When the ACF piece 601 to be attached this time to the glass substrate 81 of the ACF tape 125 reaches the position facing the glass substrate 81 by the drawing operation of the ACF tape 125 by the drawing portion 109, the suction portion 105 is moved to the ACF tape 125. And then the drawer clamper 191 is opened. And the suction part 105 descend | falls with the nail | claw members a and b shown in FIG. 1, and positions the ACF piece 601 in the sticking surface level of the glass substrate 81. FIG. When the suction unit 105 is lowered, the drawer clamper 191 remains in that position in an open state.

  Next, in this state, the crimping tool 93 is lowered, the ACF piece 601 positioned on the glass substrate 81 is pressed against the glass substrate 81, and thermocompression bonded to a predetermined position. After the thermocompression bonding, the crimping tool 93 rises to the standby position, and the suction part 105 also rises to the original position together with the claw members a and b while holding the ACF tape 125 by suction. The slack of the ACF tape 125 when the suction unit 105 is lifted is removed by the movement of the dancer rollers 173 and 115 in the ACF tape supply unit 107 and the ACF tape winding unit 111.

  Thereafter, the release paper 123 is peeled off from the ACF piece 601 thermocompression bonded onto the glass substrate 81 using a release paper peeling device (not shown).

  On the other hand, as described above, the ACF piece 601 to be attached to the glass substrate 81 of the ACF tape 125 at this time reaches the position facing the glass substrate 81 by the movement of the drawer portion 109, and the suction portion 105 holds the ACF tape 125 by suction. When the drawer clamper 191 is opened, the ACF tape supply unit 107 drives the ACF tape supply reel 171 to supply the ACF tape 125. The supply reel 171 stops when the supply unit upper limit sensor 551 detects the dancer roller 173 reaching the upper limit position. The ACF take-up unit 111 drives the take-up reel 113 to take up the release paper 123. The take-up reel 113 stops when the take-up side lower limit sensor 557 detects that the dancer roller 115 reaches the lower limit position.

  Next, incision formation and partial peeling will be described.

  6A shows a sample pattern for drawing out the ACF tape 125, and FIG. 6B shows the distance between the tip of the half cutter 101 and the center of the peeling head 133. FIG. As shown in FIG. 6A, the length of the ACF piece 601 is 100 mm, the length of the ACF cut piece 603 is 5 mm, and the length of the ACF piece 605 is 60 mm. As shown in FIG. 6B, the distance between the tip of the half cutter 101 and the center of the peeling head 133 is 25 mm. Reference numeral 610 denotes a previous cutting position, and it is assumed that the half cutter 101 is facing this position.

  FIGS. 7 to 15 are views showing the state of the ACF tape 125 before and after the notch formation and before and after the ACF cut piece peeling. FIG. 7 shows a state before the first notch is formed, and FIG. FIG. 9 shows the state after removing the slack caused by the first cut formation, FIG. 10 shows the state before forming the second cut, and FIG. 11 shows the second cut state. FIG. 12 shows the state after removing the slack caused by the second notch formation, and FIG. 13 shows the state before peeling off the ACF cut piece between the first and second notches. 14 shows the state after the ACF cut piece between the first and second cuts is peeled off, and FIG. 15 removes the slack caused by peeling off the ACF cut piece between the first and second cuts. The state after having done is shown, respectively.

  A method of forming the first and second cuts and peeling the ACF cut piece 603 between the first and second cuts will be described with reference to these drawings as follows.

  The suction of the suction block 151 is turned on. In the ACF tape drawer 109, the drawer clamper 191 is opened, the drawer clamper 191 is moved 100 mm toward the suction block 151, the drawer clamper 191 is closed, and the suction of the suction block 151 is turned off. After that, the drawer clamper 191 returns to the drawer standby position with the ACF tape 125 interposed therebetween. The first cut position is on the half cutter 101 (FIG. 7).

  After the suction of the suction block 151 is turned ON, the half cutter 101 is raised and lowered to make a first cut 620 in the ACF 121. When the half cutter 101 is lowered, the ACF 121 attached to the half cutter 101 is pulled downward, so that the ACF tape 125 is loosened (FIG. 8).

  When the suction of the suction block 151 is turned OFF, the dancer roller 173 of the tape supply unit 107 is pulled upward due to the influence of the weight 176, so that the slack of the ACF tape 125 is removed (FIG. 9).

  The suction block 151 is turned on, the drawer clamper 191 is opened, the drawer clamper 191 is moved 5 mm toward the suction block 151, the drawer clamper 191 is closed, and the suction block 151 is turned off, and then the drawer clamper 191 is turned off. Returns to the standby position with the ACF tape 125 sandwiched therebetween. The second cut position is on the half cutter 101 (FIG. 10).

  After the suction block 151 is turned ON, the half cutter 101 is raised and lowered to make a second cut 630 in the ACF 121. When the half cutter 101 is lowered, the ACF 121 attached to the half cutter 101 is pulled downward, so that the ACF tape 125 is loosened (FIG. 11).

  When the suction of the suction block 151 is turned OFF, the dancer roller 173 of the tape supply unit 107 is pulled upward due to the influence of the weight 176, so that the slack of the ACF tape 125 is removed (FIG. 12).

  The suction block 151 is turned on, the drawer clamper 191 is opened, the drawer clamper 191 is moved 22.5 mm to the suction block 151 side, the drawer clamper 191 is closed, and the suction block 151 is turned off, and then the drawer clamper 191 is turned off. Return to the standby position with the ACF tape 125 sandwiched therebetween. Since the distance between the tip of the half cutter and the center of the peeling head is 25 mm, the length obtained by subtracting (peeling dimension: 5 mm) / 2 from (the distance between the tip of the half cutter and the center of the peeling head: 25 mm) (that is, 22. By pulling out the ACF tape 125 by 5 mm), the center of the ACF cut piece 603 comes on the center of the peeling head 133 (FIG. 13).

  After the suction block 151 is turned ON, the peeling head 133 is raised and lowered to peel the ACF cut piece 603 from the release paper 123. When the peeling head 133 is lowered, the ACF cut piece 603 attached to the peeling tape 131 is pulled downward, so that the ACF tape 125 is loosened (FIG. 14).

  When the suction of the suction block 151 is turned off, the dancer roller 173 of the tape supply unit 107 is pulled upward due to the weight 176, so that the slack of the ACF tape 125 is removed (FIG. 15).

  In this way, the formation of the first and second cuts and the separation of the ACF cut piece 603 between the first and second cuts are completed.

  The suction block 151 is turned ON, the drawer clamper 191 is opened, the drawer clamper 191 is moved (60-22.5) mm toward the suction block 151 side, the drawer clamper 191 is closed, and the suction block 151 is turned OFF. The drawer clamper 191 returns to the drawer standby position with the ACF tape 125 interposed therebetween.

As a result, the third cutting position comes on the half cutter 101.

  After the suction block 151 is turned ON, the half cutter 101 is raised and lowered to make a third cut 640 in the ACF 121. When the half cutter 101 is lowered, the ACF 121 attached to the half cutter 101 is pulled downward, so that the ACF tape 125 is loosened.

  When the suction of the suction block 151 is turned OFF, the dancer roller 173 of the tape supply unit 107 is pulled upward due to the influence of the weight 176, so that the slack of the ACF tape 125 is removed.

  According to the above-described embodiment, the slack that occurs when the notch is formed in the ACF 121 and when the ACF cut piece 603 is peeled off turns off the suction of the suction block 151, whereby the ACF tape 125 is pulled out by the ACF tape drawer 109. It is solved before starting. When the slack is eliminated, the ACF tape 125 is only subjected to a pulling force by the dancer roller 173 of the tape supply unit 107. For this reason, since the impact force applied to the ACF tape 125 at the time of slack removal can be reduced, the elongation of the ACF tape can be suppressed as much as possible. Therefore, the conveyance accuracy of the tape member 125 can be increased, and as a result, the ACF piece 601 can be attached. Position accuracy can be improved.

  In the above-described embodiment, the dancer roller is used as a means for applying a tensile force for removing the slack. However, the dancer roller is not necessarily required, and a driving means for removing the slack may be separately provided.

  In the embodiment, the ACF cut piece 603 is formed between the ACF pieces 601 and 605 attached to the glass substrate 81, but this is not always necessary.

  In the embodiment, the case where the ACF pieces (tape pieces) 601 and 605 and the ACF cut pieces 603 are respectively formed by cutting and forming the ACF 121 using the half cutter 101 has been described. Incisions are formed in advance in the transported ACF 121 at intervals as shown in FIG. 6A, and the ACF cut pieces 603 are peeled off by the ACF tape peeling portion 103 described above, so that adjacent ACF cut pieces are separated. The formed ACF pieces 601 and 605 may be pressed against the member to be adhered and adhered.

  Furthermore, in the embodiment, the ACF is described as an example of the tape member. However, the tape member may not be the ACF as long as the tape member is transported together with the release paper.
