Description

  The present invention relates to a sticking apparatus and a sticking method for sticking an adhesive tape for mounting an electronic component on a side portion of a substrate.

  For example, in the manufacturing process of flat panel displays such as liquid crystal display panels and plasma display panels, electronic components such as TCP (Tape Carrier Package) are placed on the upper surface of the side of a glass substrate. There exists the process of sticking through the adhesive tape which consists of.

  Before the electronic component is attached to the upper surface of the side portion of the substrate, there is a step of attaching the adhesive tape cut to a predetermined length to the upper surface of the side portion of the substrate. Adhesive tapes are affixed to a release tape, which is wound around a supply reel.

  When attaching an electronic component to the upper surface of the side part of the substrate with an adhesive tape, first, the adhesive tape fed out from the supply reel together with the release tape is cut into a predetermined length. The cutting length of the adhesive tape at this time is set to a length corresponding to the length of the terminal portion composed of a plurality of terminals provided on the upper surface of the side portion of the substrate, for example.

  Next, the adhesive tape cut to a predetermined length is pulled out together with the release tape by, for example, a chuck, positioned so as to face the terminal portion on the side surface of the substrate placed on the table, and then cut. The pressure-sensitive adhesive tape is applied to the substrate with a pressure tool.

  And if an adhesive tape is stuck on a board | substrate, a release tape will be peeled from the adhesive tape with a release roller.

  In patent document 1, after sticking the other side of the adhesive tape having one side attached to the release tape over the entire length in the longitudinal direction of one side of the substrate, the roller unit is attached to the adhesive tape attached to the substrate. It is shown that the release tape is peeled off from the adhesive tape by being driven along.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing a sticking device for an adhesive tape 2 with a release tape 1, and this sticking device is driven in the X, Y, Z and θ directions by a first driving means 4. Table 5 is included. As shown in FIG. 2, a substrate W made of a liquid crystal display panel is supplied and mounted on the upper surface of the table 5 with one side protruding outward from one end of the table 5.

The backup tool 6 has a width dimension equal to or greater than the length dimension of one side portion of the substrate W, and at least the upper end portion has a flat plate shape along the longitudinal direction of one side portion of the substrate W.

  Above the backup tool 6, a pressurizing tool 7 as a pressurizing unit is provided so as to be driven in the Z direction by the second driving unit 8. The pressure tool 7 is formed to have substantially the same width as the backup tool 6, and at least a lower end portion is a flat plate shape corresponding to the upper end portion of the backup tool 6.

  The adhesive tape 2 with the release tape 1 is wound around a supply reel 11. The adhesive tape 2 with the release tape 1 fed out from the supply reel 11 is adhered to the upper surface of one side portion of the substrate W, the lower surface of which is supported by the backup tool 6, as will be described later by the pressure tool 7. The Only the release tape 1 is wound on the take-up reel 12.

  The supply reel 11 is rotationally driven by the third driving means 9, and the take-up reel 12 is rotationally driven by the fourth driving means 10.

  In this embodiment, as shown in FIG. 3, the adhesive tape 2 is attached to the upper surface of one side portion of the substrate W with a length over almost the entire length of the one side portion.

  A peeling unit 16 constituting a peeling means is provided on one end side in the width direction of the table 5. The peeling unit 16 includes a mounting plate 21, and a lower roller 22 that is a peeling roller and an upper roller 23 that is also a peeling roller are rotatably provided at a position higher than the lower roller 22. ing.

  On the outer peripheral surfaces of the lower roller 22 and the upper roller 23, portions located downstream of the adhesive tape 2 attached to the substrate W of the release tape 1 are sequentially engaged. The peeling unit 16 is driven along the X direction indicated by an arrow in FIG.

  If the peeling unit 16 is driven in the −X direction as indicated by the chain line from the position indicated by the solid line in FIG. 1, the release from the pressure-sensitive adhesive tape 2 that is pressure-bonded to the substrate W by the pressure tool 7. The tape 1 is peeled off as will be described later.

  The release tape 1 led out from the upper roller 23 is wound around the take-up reel 12 through one guide roller 13 positioned on one end side in the width direction of the table 5.

  A cutting mechanism 24 is provided near the other guide roller 13 at the other end in the width direction of the table 5. The cutting mechanism 24 has a holding member 25 disposed with its lower end surface in contact with the release tape 1 and a cutter 26 provided opposite to the lower side of the holding member 25. The cutter 26 is a cylinder (not shown). Is driven in the vertical direction.

  Between the holding member 25 and the cutter 26, the adhesive tape 2 with the release tape 1 fed out from the supply reel 11 runs with the adhesive tape 2 facing downward. When the cutter 26 of the cutting mechanism 24 is driven in the upward direction, only the adhesive tape 2 is cut while the release tape 1 and the adhesive tape 2 are pressed against the lower surface of the holding member 25. Yes.

  As shown in FIG. 4A, the cutting mechanism 24 forms cutting lines c at two places with a predetermined width as shown in FIG. 4A, and a portion r between the two cutting lines c is not shown. Removed by release tape. Thereby, the adhesive tape 2 is formed with a removed portion m that is divided into a predetermined length and removed by the release tape as shown in FIG.

  A feed chuck 27 is disposed between the peeling unit 16 and one guide roller 13. The feed chuck 27 is reciprocated in the horizontal direction indicated by the arrow X in FIG.

  If the feed chuck 27 is driven in the + X direction while sandwiching the release tape 1 led out from the peeling unit 16, the adhesive tape 2 with the release tape 1 is fed out from the supply reel 11.

  When the feed chuck 27 is driven in the + X direction by the sixth drive means 28, the third drive means 9 that rotationally drives the supply reel 11 and the fourth drive means 10 that rotationally drives the take-up reel 12. Operate synchronously. Thereby, when the adhesive tape 2 with the release tape 1 is unwound from the supply reel 11, the release tape 1 removed by the adhesive tape 2 being stuck to the substrate W is taken up by the take-up reel 12. .

  The feed chuck 27 is driven in the + X direction by a distance that allows the adhesive tape 2 with the release tape 1 to be pulled out from the supply reel 11 with a length corresponding to one side of the substrate W.

  When the adhesive tape 2 with the release tape 1 is pulled out by a predetermined length, the cutter 26 of the cutting mechanism 24 is driven as shown in FIGS. After forming the first cutting line c, the adhesive tape 2 with the release tape 1 is further fed slightly to form the second cutting line c, and the portion r between the pair of cutting lines c is It is removed and a removal portion m is provided.

  After forming the removal portion m, the adhesive tape 2 is pulled out with a length corresponding to the length dimension of one side of the substrate W, and the removal portion m is provided again at that position. As a result, the adhesive tape 2 is divided by a length corresponding to one side of the substrate W.

  As described above, the take-up reel 12 winds the release tape 1 in synchronism when the adhesive tape 2 with the release tape 1 is pulled out from the supply reel 11 by the feed chuck 27. That is, when the pressure-sensitive adhesive tape 2 divided into a predetermined length is pressed by the pressure tool 7 and attached to the substrate W, and only the release tape 1 is peeled off from the pressure-sensitive adhesive tape 2 as described later, A portion of the release tape 1 corresponding to the length peeled from the adhesive tape 2 is wound around the take-up reel 12.

The first to sixth driving means 4, 8, 9, 10, 20, and 28 are controlled by a control device 31 as the control means shown in FIG.
The first driving means 4 is configured to remove the release tape 1 from the control device 31 after the adhesive tape 2 divided into a predetermined length is attached to the substrate W. The table 5 on which the substrate W is placed and fixed is driven by a control signal to displace the substrate W. In this embodiment, the table 5 is slightly driven in the width direction of the adhesive tape 2 attached to the substrate W, that is, in the −Y direction perpendicular to the direction indicated by the arrow X in FIG.

  As a result, the portion 1a attached to the adhesive tape 2 attached to the substrate W of the release tape 1 is displaced in the −Y direction with respect to the other portion 1b. This displacement is indicated by e in FIG.

  Next, the operation when the adhesive tape 2 is divided into two parts on the upper surface of one side portion of the substrate W and attached by the attaching apparatus having the above configuration will be described with reference to FIG.

  First, the feed chuck 27 is driven in the + X direction by the sixth driving means 28, and the adhesive tape 2 with the release tape 1 is pulled out from the supply reel 11 by substantially the same length as one side of the substrate W. When the adhesive tape 2 is pulled out, the cutter 26 is operated to put a pair of cutting lines c in the adhesive tape 2, and the removal portion m is provided by removing the portion r between them.

  If the removal portion m is provided, the adhesive tape 2 with the release tape 1 is further drawn out with a length corresponding to the side portion of the substrate W, and at that time, the removal portion m is formed on the adhesive tape 2 by the cutter 26 again. To do. Thereby, the adhesive tape 2 is divided into approximately the same length as the length of one side of the substrate W.

  Next, the table 5 is driven in the X and Y directions (horizontal direction) by the first driving means 4, and the length of one side portion of the substrate W held on the upper surface of the table 5 is projected from the upper surface of the table 5. One end of the direction is positioned above the backup tool 6. Next, the table 5 is driven downward in the Z direction, and the lower surface on one end of one side of the substrate W is supported by the upper end surface of the backup tool 6 as shown in FIG.

  Thereby, as shown in FIG. 1, the divided portion of the adhesive tape 2 is positioned so as to face the upper surface of one end portion in the longitudinal direction of the substrate W supported by the backup tool 6.

  When the substrate W is positioned with respect to the adhesive tape 2, the pressing tool 7 is driven in the downward direction by the second driving means 8. Thereby, as shown in FIG. 6, the divided portion of the adhesive tape 2 is pressure-bonded to the upper surface of one side portion of the substrate W.

  If the part of the adhesive tape 2 divided by the pressure tool 7 is attached to the substrate W and the pressure tool 7 is raised, the table 5 on which the substrate W is placed is indicated by an arrow Y in FIG. Drive slightly with respect to the -Y direction. That is, the control device 31 controls the driving of the first driving unit 4. Thereby, as shown by e in FIG. 5, the portion 1a attached to the adhesive tape 2 attached to the substrate W of the release tape 1 is displaced in the −Y direction with respect to the other portion 1b.

  Thus, when the substrate W is driven in the −Y direction, the peeling unit 16 is driven in the −X direction as indicated by an arrow in FIG. Thereby, the release tape 1 is pulled upward, which is the direction in which the release tape 16 is peeled off from the adhesive tape 2 adhered to the substrate W by the lower roller 22 and the upper roller 23 of the peeling unit 16.

  The portion 1a attached to the adhesive tape 2 of the release tape 1 is displaced by a displacement amount e in the −Y direction with respect to the other portion 1b. Thereby, the part corresponding to the terminal of the adhesive tape 2 of the release tape 1 is deformed in an oblique direction as shown in FIG. That is, at the end of the adhesive tape 2, the release tape 1 is inclined obliquely.

  Therefore, when peeling of the release tape 1 is started by the peeling unit 16, the part attached to the longitudinal end of the adhesive tape 2 of the release tape 1 is the lower roller 22 and the upper roller of the peeling unit 16. 23 is pulled in an oblique direction with respect to the width direction of the adhesive tape 2.

  As a result, the release tape 1 concentrates at one end in the width direction of the end of the adhesive tape 2 indicated by S in FIG. 5 and starts peeling from the point S. Therefore, the release tape 1 is orthogonal to the width direction. Compared with the case of pulling in the direction of pulling, the peeling force does not disperse, and the release tape 1 can be peeled easily and smoothly.

  Thus, if the release of the release tape 1 can be started easily and smoothly, the adhesive tape 2 attached to the substrate W is prevented from being pulled more strongly than necessary by the release tape 1. Therefore, it is possible to prevent the adhesive tape 2 from being peeled off from the substrate W.

  Furthermore, when the release of the release tape 1 from the adhesive tape 2 is started, the release tape 1 can be pulled obliquely by driving the table 5 in the −Y direction to displace the substrate.

  That is, since the table 5 is driven in the X, Y, Z, and θ directions by the first driving means 4, the release tape 1 can be surely peeled using the inherent function. The mold release tape 1 can be reliably peeled without causing any complication.

  When the release tape 1 is peeled from the adhesive tape 2 adhered to the substrate W, the feed chuck 27 is driven in the + X direction by the sixth driving means 28. In synchronization therewith, the supply reel 11 and the take-up reel 12 are rotationally driven by the third and fourth drive means 9, 10, and the part peeled off from the adhesive tape 2 of the substrate W of the release tape 1 is taken up by the take-up reel 12. And a new adhesive tape 2 is fed out from the supply reel 11.

  Further, the peeling unit 16 is returned to the initial position by the fifth driving means 20, and the feed chuck 27 is returned to the initial position by the sixth driving means 28. Thereafter, the above-described operation is repeated.

  In the above-described embodiment, when the release tape 1 is peeled off, the portion 1a attached to the adhesive tape 2 of the release tape 1 together with the substrate W by driving the table 5 in the -Y direction is compared with the other portion 1b. However, the table 5 may be driven in the + Y direction so that the portion 1a attached to the adhesive tape 2 of the release tape 1 together with the substrate W may be displaced in the + Y direction.

  Further, instead of displacing the table 5 in the Y direction, the adhesive tape of the release tape 1 is rotated by rotating the table 5 at a slight angle in the θ direction, that is, the axis perpendicular to the plate surface of the substrate W in the horizontal direction. The part attached to 2 may be displaced in the rotational direction with respect to the other parts, so that the release of the release tape 1 may be started in an inclined state with respect to the width direction.

  In the above embodiment, when the release tape is peeled off, the peeling unit 16 is driven in the −X direction, but the table 5 may be driven in the + X direction instead. That is, when peeling the release tape, at least one of the table 5 and the peeling unit 16 may be driven in the X direction. In other words, the table 5 and the peeling unit 16 may be driven relative to the X direction.
