Description

  The present invention relates to an adhesive tape attaching apparatus and an attaching method for cutting an adhesive tape attached to a release tape to a predetermined length and attaching the adhesive tape to an electronic component.

  For example, when manufacturing a liquid crystal display device, a mounting device for mounting TCP as an electronic component on a panel of the liquid crystal display device as a substrate is used. The TCP is punched from the carrier tape by a mold and then supplied to an index table that is rotationally driven by a predetermined angle. The index table is provided with a plurality of suction heads in the circumferential direction at intervals corresponding to the rotation angle per time. The TCP punched out by the mold is sequentially supplied to a plurality of suction heads.

  The panel is positioned and placed on an XY table, and is driven in the XY direction by the XY table. At the mounting position of the index table, the alignment mark provided on the TCP and the alignment mark provided on the panel are imaged by the imaging camera, and the imaging signal is processed by the image processing unit. Then, based on the processing of the imaging signal in the image processing unit, the driving of the XY table is controlled so that the panel alignment mark is aligned with the TCP alignment mark so that the panel is positioned. It has become.

  When the panel is positioned with respect to the TCP, the suction head holding the TCP is driven in the downward direction, and the TCP is applied to an adhesive tape made of an anisotropic conductive member provided on the panel. In other words, it is designed to be implemented. A conventional mounting apparatus that mounts TCP on a substrate using an index table is disclosed in, for example, Patent Document 1.

  By the way, in the mounting apparatus disclosed in Patent Document 1, an adhesive tape for mounting TCP on a substrate is adhered over the entire length in the longitudinal direction on one side of the substrate, and the TCP is mounted there at a predetermined interval. I am doing so.

  For this reason, the portion of the adhesive tape located between the TCPs attached at a predetermined interval becomes a portion that is not necessary for mounting the TCP, so that the portion is wasted, leading to an increase in cost.

  Therefore, recently, it is considered that the adhesive tape is not attached to the substrate, and the adhesive tape cut to a length corresponding to the width dimension of the TCP is attached to the TCP, thereby eliminating the waste of the adhesive tape. ing. Such prior art is disclosed in Patent Document 2.

  In Patent Document 2, the adhesive tape attached to the release tape is cut at a length corresponding to the width dimension of the TCP, and the adhesive tape faces up to the electronic component held by the suction head of the index table. Position so that.

  Next, the adhesive tape is pushed up together with the release tape and attached to the TCP held by the suction head of the index table, and then the release tape is peeled off from the lower surface of the adhesive tape. And TCP is mounted by sticking the surface by which the release tape of the adhesive tape was peeled off to a board | substrate.

  When the TCP is mounted on the substrate, the index table is rotated by a predetermined angle, and the release tape is pitch-fed by a predetermined length. Then, the new adhesive tape cut to a predetermined length is opposed to the TCP held by the suction head of the index table, the adhesive tape is attached to the TCP, and then the TCP is mounted on the substrate repeatedly. It is done.

  In Patent Document 2, the release tape to which the above-mentioned adhesive tape is attached is paid out from a supply reel and taken up on a take-up reel. Therefore, by setting the winding length of the release tape by the supply reel, new adhesive tapes cut to a predetermined length can be sequentially positioned opposite to the TCP held by the suction head.

  By the way, in the technical document 2, as described above, the release tape is taken up by the take-up reel, and the new adhesive tape cut to a predetermined length is positioned with respect to the TCP held by the suction head. The release tape from which the adhesive tape has been removed is taken up on the take-up reel.

  For this reason, when the take-up reel is used repeatedly, the release tape wound on the take-up reel must be removed and discarded, which may take time.

  Therefore, it is considered that the release tape is fed by a fixed chuck and a drawer chuck instead of the take-up reel. That is, in the standby position state, the drawer chuck is positioned above the fixed chuck.

  When the release tape is clamped by the drawer chuck, the fixed chuck is opened and the drawer chuck is lowered. Accordingly, when the release tape is pulled out by a predetermined length, the release tape is clamped and fixed by the fixing chuck in the pulled-out state to prevent the release tape from loosening.

  Next, the drawer chuck is opened and raised to a standby position, and then the drawer chuck is closed and the release tape is clamped, and then the release tape is clamped by the fixed chuck and the drawer chuck is lowered. By repeating this operation, the release tape is pitch-fed by a predetermined length. As a result, the part of the release tape that has been removed by sticking to the TCP is dropped and collected in the collection container.

  In this way, compared to the case where a take-up reel is used, the processing of the release tape from which the adhesive tape has been adhered and removed becomes a container, and thus there is an advantage that productivity can be improved.

  By the way, the adhesive tape is cut into a predetermined length by a cutter in a state of being attached to the release tape. The adhesive tape is made of an adhesive resin. Therefore, when the adhesive tape is cut by the cutter, even after the adhesive tape cut to a predetermined length is removed by sticking to the TCP, a part of the adhesive tape, in particular, the part that is pressed and cut by the cutter Sometimes it remains attached to the release tape.

  In such a state, as described above, the opening and closing of the fixed chuck and the drawer chuck and the vertical movement of the drawer chuck are controlled to pitch-feed the release tape, and then the fixed chuck is opened and the release tape is clamped by the drawer chuck. When the pitch is fed, the release tape may adhere to the fixed chuck due to a part of the adhesive tape remaining on the release tape. Even if the fixed chuck is released, the release tape falls down due to its own weight. Sometimes it disappears.

  Therefore, when the release tape is stuck to the fixed chuck and the drawer chuck is moved up and down as described above and the pitch of the release tape is repeated, the release tape attached to the fixed chuck is removed from the drawer chuck and It may happen that the pitch of the release tape becomes entangled with the fixed chuck.

  According to the present invention, when a release tape is fed by a fixed length between a fixed chuck and a drawer chuck, even if the release tape adheres to the fixed chuck, the adhesive tape is designed not to be entangled with the drawer chuck or the fixed chuck. It is providing the sticking apparatus and the sticking method.

This invention is an attaching device for attaching an adhesive tape attached to a release tape to an electronic component ,
An adhering means for adhering the adhesive tape to an electronic component;
A feeding means for intermittently feeding the release tape at a predetermined pitch ;
Comprising
Said feeding means includes a fixing chuck for opening and closing the pair of holding pieces for holding the above release tape, which movement driving the pair of holding pieces for holding the above release tape feeding direction of the opening and closing and the release tape A pair of clamping pieces of the fixed chuck, and a pair of clamping pieces of the stationary chuck are opened up to an interval through which the clamping piece of the drawer chuck that clamps the release tape by closing the pair of clamping pieces can pass; The pressure-sensitive adhesive tape is characterized in that the holding piece is configured to be able to be opened to an interval at which the holding piece of the fixed chuck that holds the release tape fed at a predetermined pitch can be passed by closing a pair of holding pieces. In the pasting device.

  According to this invention, when the fixed chuck is opened and the drawer chuck is lowered to pitch-feed the release tape, the release tape attached to the fixed chuck is peeled off from the fixed chuck by the movement of the drawer chuck. The tape can be reliably fed without being pulled out and entangled with the chuck.

  The release tape 20 is pitch-fed by a predetermined length by a feeding device 40 (shown in FIG. 4) described later, and the adhesive tape 19 attached to the release tape 20 in the process is the width of the TCP 3. It is cut to the same length as the dimension.

  The component supply unit 21 includes a mold 23 for punching out the TCP 3 from the carrier tape 22 as shown in FIG. The mold 23 includes an upper mold 23a that is driven in the vertical direction, and a lower mold 23b that is fixedly disposed so as to face the upper mold 23a. The upper mold 23a is provided with a punch 24. The mold 23b is provided with a through hole 25 into which the punch 24 is inserted when the upper mold 23a is lowered.

  The carrier tape 22 is passed between the upper mold 23a and the lower mold 23b. When the upper mold 23a is lowered, the TCP 3 is punched, and when it is raised, the carrier tape 22 is sent at a predetermined pitch in the arrow direction indicated by + Y. In this state, TCP3 can be punched out.

  A receiving tool 26 is disposed below the lower mold 23b. The receiver 26 is driven by a Zθ driving source 28 provided on the X table 27 in the Z direction which is the vertical direction and the θ direction which is the rotational direction. The X table 27 is provided on the Y table 29 so as to be movable along the X direction orthogonal to the Y direction. The Y table 29 is provided with an X drive source 31 for driving the X table 27 along the X direction.

  The Y table 29 is provided on a base 32 disposed along the Y direction indicated by an arrow in FIG. 1 so as to be movable along the Y direction. One end of the base 32 is provided with a Y drive source 33 for driving the Y table 29 along the Y direction. The other end of the base 32 is located below the receiving position A of the index table 4.

  When the receiving tool 26 is lowered by receiving the TCP 3 punched from the carrier tape 22 by the mold 23, the Y table 29 is driven from one end of the base 32 to the other end by the Y driving source 33 as shown by a chain line in FIG. The As a result, the holder 26 holding the TCP 3 is positioned below the receiving position A of the index table 4 as indicated by a chain line in FIG.

  When the receiver 26 is positioned below the receiving position A, the receiver 26 is driven in the upward direction, and one end of the TCP 3 held on the receiver 26 by the suction head 18 provided at the lower end of the movable body 14. Adsorb the upper surface of the part.

  When the suction head 18 sucks the TCP 3 at the receiving position A, the index table 4 is rotated 90 degrees, and the suction head 18 is positioned at the cleaning position B. At the cleaning position B, the terminal portion of the TCP 3 sucked and held by the suction head 18 is brushed by a brush (not shown). Thereby, the dirt adhering to the terminal portion is removed.

  When the dirt of the TCP 3 is removed at the cleaning position B, the index table 4 is rotated 90 degrees and the TCP 3 is positioned at the sticking / peeling position C. In the sticking / peeling position C, the adhesive tape 19 cut to a predetermined length is stuck to the terminal portion of the TCP 3.

  At the sticking / peeling position C, as shown in FIG. 4, a pressing block 34 having a size substantially the same as that of the suction head 18 is provided opposite to the suction head 18 positioned at the sticking / peeling position C. Yes. The pressing block 34 includes a heater 34a.

  The pressing block 34 is attached to a rod 35a of a driving cylinder 35 arranged with its axis perpendicular, and can be driven in the vertical direction indicated by an arrow in FIG. As a result, when the drive cylinder 35 is operated and the rod 35a is driven in the protruding direction, the pressing block 34 rises toward the suction head 18.

  On the upper surface side of the pressing block 34, the release tape 20 having the adhesive tape 19 attached to one surface is caused to run by the feeding device 40 with the adhesive tape 19 facing upward. .

  The feeding device 40 has a supply reel 41 around which the release tape 20 having the adhesive tape 19 attached to one surface is wound. The release tape 20 fed out from the supply reel 41 is converted in the traveling direction upward in the vertical direction by the first guide roller 42.

  The release tape 20 whose traveling direction has been converted by the first guide roller 42 is converted to the horizontal direction by the second guide roller 43, and then the traveling direction is converted downward by the third guide roller 44. The As a result, the release tape 20 travels horizontally between the second guide roller 43 and the third guide roller 44. This traveling direction is set to + X as shown by an arrow in FIG.

  As shown in FIG. 3 and FIG. 4, the portion where the traveling direction of the release tape 20 is converted upward in the vertical direction by the first guide roller 42 is along the plate surface of the belt-like support block 45. It is supposed to run.

  In the part where the adhesive tape 19 runs vertically facing the support block 45, a cutter 48 having two blades is shown by an arrow in FIG. 3 by a drive source 47 such as a cylinder or a linear motor constituting the cutting means 46. Driven in a direction approaching the adhesive tape 19. Thereby, two cutting lines 19a are formed on the adhesive tape 19 at a predetermined interval. The cutting amount by the cutter 48 is set so that the release tape 20 is not cut by the cutter 48 when the adhesive tape 19 is cut.

  The part separated from the other part by the two cutting lines 19 a of the adhesive tape 19, that is, the extracted part 19 b is extracted by the extracting means 51 arranged above the cutting means 46. Thereby, the adhesive tape 19 is separated into a predetermined length, that is, a length corresponding to the TCP 3.

  The extraction means 51 includes a driving source 51a such as a cylinder or a linear motor, a pressing portion 51b driven in the direction of coming into contact with and separating from the adhesive tape 19 by the driving source 51a, and the extraction portion 19b by the pressing portion 51b. It has a removal tape 52 to be pressed.

  When a part of the removal tape 52 is pressed against the extraction part 19b of the adhesive tape 19 by the pressing part 51b, the extraction part 19b is adhered to the removal tape 52 and removed. The removal tape 52 is fed out from a supply reel (not shown) and is wound up by a predetermined length by a take-up reel (not shown).

  The release tape 20 to which the adhesive tape 19 cut to a predetermined length is attached is guided by the second and third guide rollers 43 and 44 and the one side to which the adhesive tape 19 is attached is directed upward. Then, it travels horizontally above the pressing block 34.

  When the adhesive tape 19 cut to a predetermined length is positioned above the pressing block 34, that is, at the sticking / peeling position C, the pressing block 34 is driven upward by the drive cylinder 35. As a result, the adhesive tape 19 is pressed together with the release tape 20 and adhered to the TCP 3 that is adsorbed and held by the adsorption head 18 positioned at the adhesion peeling position C.

  When the adhesive tape 19 is attached to the TCP 3, the release tape 20 attached to the adhesive tape 19 is peeled off by the release roller 54 driven in the vertical direction and the X direction by the X / Z drive source 53. That is, after the release roller 54 is driven downward in the Z direction, it is driven in the −X direction opposite to the + X direction, which is the traveling direction of the release tape 20. As a result, the adhesive tape 19 attached to the TCP 3 is peeled off from the TCP 3.

  The TCP 3 with the adhesive tape 19 attached at the attaching / detaching position C is transported to the mounting position D by the index table 4, and is held by the panel table 2 by driving the suction head 18 in the downward direction. Mounted on the side of the panel 1.

  After the adhesive tape 19 cut to a predetermined length is attached to the TCP 3, the release tape 20 is pitch-fed by a predetermined length by the feeding device 40 described above. That is, pitch feeding is performed at a length corresponding to the pitch interval P (shown in FIG. 3) of the adhesive tape 19 cut by the cutting means 46.

  As shown in FIG. 4, the feeding device 40 is disposed corresponding to a portion where the release tape 20 is turned downward by the third guide roller 44. That is, the feeding device 40 includes a pair of sandwiching pieces 56a positioned above the stationary chuck 56 in a standby state, and a pair of sandwiching pieces 56a in which the pair of sandwiching pieces 56a is driven to open and close in the horizontal direction by the first opening / closing drive source 57. The drawer chuck 58a is driven to open and close in the horizontal direction by the second opening and closing drive source 59, and can be driven in the vertical direction (Z direction) integrally with the second opening and closing drive source 59 by the vertical drive source 60. 58.

  The first opening / closing drive source 57 for opening / closing the fixed chuck 56, the second opening / closing drive source 59 for opening / closing and vertically driving the drawer chuck 58, and the driving of the vertical drive source 60 are shown in FIG. The control device 62 shown in FIG.

  Accordingly, the release tape 20 is pitch-fed by a predetermined length in the + X direction. That is, the release tape 20 is fed out from the supply reel 41 by a predetermined length by the feeding device 40.

  Then, the release tape 20, which has been fed out by a predetermined length by the feeding device 40 and the adhesive tape 19 is adhered and removed, falls into a collection container 63 disposed below the fixed chuck 56 as will be described later. To be housed.

  The control device 62 drives not only the first opening / closing drive source 57 of the fixed chuck 56 and the second opening / closing drive source 59 and the vertical drive source 60 of the drawer chuck 58 but also other driving means. It comes to control.

  The other drive means are the X drive source 7, Y drive source 9, θ drive source 10 a of the panel table 2, θ drive source 12 of the index table 4, mounting cylinder 17, Z / θ drive of the component supply unit 21. Source 28, X drive source 31, Y drive source 33, heater 34a, drive cylinder 35, drive source 47 of the cutting means 46, drive source 51a of the extracting means 51, X / Z drive source for driving the release roller 54 53.

  Next, the operation of pitch-feeding the release tape 20 by the feeding device 40 will be described with reference to FIGS.

  FIG. 6A shows a standby state. In the standby state, the drawer chuck 58 is positioned above the fixed chuck 56, and the chucks 56 and 58 sandwich and fix the release tape 20. The distance between the fixed chuck 56 and the drawer chuck 58 at this time is m. This distance m is set to one half of the pitch P of the adhesive tape 19 cut to a predetermined length by the cutting means 46 shown in FIG.

  When the release tape 20 is pitch-fed, the pair of clamping pieces 56a of the fixed chuck 56 are opened by the first opening / closing drive source 57 as shown in FIG. At this time, there is a case where debris generated at the time of cutting the adhesive tape 19 remains on the release tape 20. In such a case, one surface on which the adhesive tape 19 of the release tape 20 is attached is a pair. It sticks to one side of the clamping piece 56a.

  6C, in the state where the release tape 20 is adhered to one clamping piece 56a of the fixed chuck 56 as shown in FIG. 6B, the pulling chuck 58 is shown by a chain line in FIG. The position is lowered from the position indicated by the solid line to the position indicated by the solid line. That is, the drawer chuck 58 passes through the pair of holding pieces 56 a of the opened fixed chuck 56 and is lowered to a position below the fixed chuck 56.

  The descending distance M of the drawer chuck 58 at this time is set to twice the distance m between the fixed chuck 56 and the drawer chuck 58 in the standby state. Therefore, the descending distance M that is twice the distance m is the same length as the pitch P of the adhesive tape 19 cut to a predetermined length by the cutting means 46 shown in FIG.

  When the release tape 20 is lowered by the pull-out chuck 58 at a lowering distance M that is twice the distance m between the fixed chuck 56 and the pull-out chuck 58 in the standby state, the release tape 20 is stuck to one holding piece 56a of the fixed chuck 56 of the release tape 20. A downward pulling force will surely act on the worn part. As a result, the portion of the release tape 20 adhered to the one clamping piece 56a of the fixed chuck 56 is reliably peeled off.

  In this way, when the release tape 20 is peeled from one of the holding pieces 56a of the fixed chuck 56, the pair of holding pieces 56a of the fixed chuck 56 are closed as shown in FIG. After holding the portion upstream of the fixed chuck 56 so as not to loosen, the pair of sandwiching pieces 58a of the drawer chuck 58 are spaced apart from the pair of sandwiching pieces 56a of the fixed chuck 56 in the closed state. To open.

  Next, as shown in FIG. 6E, the drawer chuck 58 is raised to the standby position. Then, by closing the pair of sandwiching pieces 58a of the drawer chuck 58, the standby state shown in FIG.

  When the pair of sandwiching pieces 58a of the drawer chuck 58 are opened and raised, the release tape 20 may adhere to one of the sandwiching pieces 58a. However, in that case, the drawer chuck 58 rises from the lowered position above the fixed chuck 56 by a distance M, so that it sticks to the clamping piece 58a of the drawer chuck 58 and the release tape 20 rises together with the clamping piece 58a. Even so, the release tape 20 is engaged with the fixed chuck 56.

  As a result, tension is applied to the part of the release tape 20 attached to the sandwiching piece 58a of the drawer chuck 58. Therefore, the release tape 20 is peeled from the sandwiching piece 58a of the drawer chuck 58 and pitch-fed by a predetermined length, that is, a distance. It falls to the collection container 63 by a length corresponding to M.

  By repeating such an operation, the release tape 20 is intermittently pitch-fed at the same distance as the pitch P of the cut adhesive tape 19. As a result, the adhesive tape 19 cut to a predetermined length is sequentially opposed to the TCP 3 held by the suction head 18 of the index table 4 at the sticking / peeling position C, and the suction head 18 is lowered at that time. If driven in the direction, the adhesive tape 19 is attached to the TCP 3.

  That is, according to the adhesive device having the above-described configuration in which the release tape 20 is pitch-fed by the fixed chuck 56 and the drawer chuck 58, even if the release tape 20 adheres to the fixed chuck 56, the fixed chuck 56 is operated by the operation of the drawer chuck 58. Since the release tape 20 attached to 56 can be peeled off, the portion of the release tape 20 from which the adhesive tape 19 has been removed can be recovered in the recovery container 63 without being entangled with the drawer chuck 58.

  FIGS. 7A to 7F show a second embodiment of the present invention. The same parts as those in the first embodiment shown in FIGS. 6A to 6E are denoted by the same position symbols, and the description thereof is omitted.

  That is, in this embodiment, the stationary chuck 56 and the drawer chuck 58 are closed as shown in FIG. 7A, and the stationary chuck 56 is opened as shown in FIG. When lowering at M, the drawer chuck 58 is driven slightly upward prior to the lowering operation. The rising distance of the drawer chuck 58 at this time is indicated by δ in FIG.

  7B, even if the release tape 20 is attached to the holding piece 56a of the fixed chuck 56 as shown in FIG. 7B, the portion attached to the holding piece 56a of the release tape 20 and the drawer chuck 58 Tension is generated between the portion sandwiched between the two.

  As a result, the portion of the release tape 20 attached to the holding piece 56a of the fixed chuck 56 is peeled off. In this case, it is desirable that the rising distance δ of the drawer chuck 58 is the minimum distance at which tension can be applied to the release tape 20.

  When the release tape 20 is peeled from the fixed chuck 56 in this way, the distance corresponding to the pitch feed of the release tape 20 from the raised position indicated by the chain line in FIG. Lower by a distance of (M + δ).

  Next, as shown in FIG. 7E, the fixed chuck 56 is closed and the drawer chuck 58 is opened, and then the drawer chuck 58 is raised to the standby position as shown in FIG. The operation of closing and returning to the standby state is repeated as shown in FIG.

  Accordingly, in the second embodiment as well, as in the first embodiment, even if the release tape 20 adheres to the fixed chuck 56, the release tape 20 is not entangled with the drawer chuck 58. The pitch can be fed and collected in the collection container 63.

  Further, when the drawer chuck 58 is raised from the lowered position shown in FIG. 7E to the standby position shown in FIG. 7F, the release tape 20 is stuck to the holding piece 58a of the drawer chuck 58. As in the first embodiment, the release tape 20 is peeled off from the sandwiching piece 58a.
