It is designed to perform the pasting operation automatically. When the control is performed so that the operator can select the pasting mode, the pasting mode selected by the operator is compared with the pasting mode specified from the signal combination pattern of each of the detection means 70 to 72. If not done, it is controlled to prohibit driving. Each of the detection means 70 to 72 can be configured by a phototube, a camera, a wide-angle imaging sensor, or the like. Further, the adhesive sheet base material detecting means 71 may be arranged upstream of the second unnecessary sheet winding means 56 in the original fabric feeding direction as indicated by a two-dot chain line in FIG.

  Next, a method for executing the pasting mode by the sheet pasting device 10 will be described.

[Single-layer aftercut application mode]
As shown in FIGS. 1 and 2, the single-layer original fabric R <b> 1 is set on the supply unit 12, and its lead end is fixed to the first winding roller 65 via the first feeding unit 50. On the other hand, the ring frame RF and the wafer W supported by the support means 11 are maintained at the positions indicated by the solid lines in FIG. At this time, the pressing member 41 is positioned above the adhesive sheet substrate SB fed between the press roller 53 and the first feeding roller 60.

  When the power is turned on, the cut detection means 70, the adhesive sheet base material detection means 71 and the release sheet detection means 72 detect the objects to be detected and output respective detection signals to the control means 17. That is, since the notch detection means 70 does not detect the notch C, the OFF signal is detected, and the adhesive sheet base material detection means 71 detects the adhesive sheet base material SB (unnecessary sheet S1) and outputs the ON signal, and the release sheet detection means. Since 72 does not detect the release sheet RL, it outputs an OFF signal to the control means 17, respectively. Based on the pattern of these signals, the control means 17 determines that the currently set original is a single layer original R1, and the adhesive sheet base SB is attached to the ring frame RF and the wafer W after the adhesive sheet base SB is attached. The single-layer aftercut application mode for forming the cut C in SB will be specified. Note that the incision detecting means is scanned in the original feed direction in order to detect a wide area (the same applies hereinafter).

  When the control means 17 specifies the single layer aftercut sticking mode, the control means outputs a signal for executing the single layer aftercut sticking mode. That is, while outputting an operation signal to the support means 11, the supply means 12, the 1st notch formation means 13, the 1st delivery means 50, and the 1st unnecessary sheet winding means 55, it is the 2nd notch formation means. 14. Control is performed so as not to output an operation signal to the second feeding means 51, the second unnecessary sheet winding means 56, the release sheet winding means 57, and the moving means 26. Note that a stop signal is output to each means to which no operation signal is output so as to stop at a predetermined position (the same applies hereinafter).

  The adhesive sheet base material SB extending between the press roller 53 and the first take-up roller 60 is lowered while the entire unit U including the pressing member 41 is lowered by driving the linear motion motor M4, while the outer table 20 and the inner table 21. Is raised, the adhesive sheet base material SB is pressed against the upper surface side of the ring frame RF (see FIGS. 4 and 5).

  Next, the cutter blade 34 is lowered by the drive of the linear motor 35, penetrates the surface of the adhesive sheet base SB, and the motor M3 is driven to rotate the arm 36 in a plane, thereby substantially reducing the adhesive sheet base SB. Cut into a circle. And while the inside is set as the sticking sheet S and the outside is classified as the unnecessary sheet S1, the cutter blade 34 moves backward.

  When the adhesive sheet substrate SB is cut in this way, the pressing roller 39 is lowered by the cylinder 38 and presses the outer peripheral side of the sticking sheet S to make one rotation, so that the outer peripheral portion of the sticking sheet S is removed. While being affixed to the ring frame RF, the pressing pad 42 is lowered by the cylinder 43 to press the affixing sheet S against the wafer W. Thereby, the ring frame RF and the wafer W are integrated. In FIG. 5, the adhesive sheet base SB is shown as being completely separated into the sticking sheet S and the unnecessary sheet S1 for easy understanding, but in practice, the sticking sheet cut into a circle is used. The outer portion of S is continuously connected as an unnecessary sheet S1.

  When the application of the application sheet S and the cutting of the adhesive sheet base material SB are completed, the linear motion motor M4 moves upward through a driving means (not shown), and the entire unit below the linear motion motor M4 is shown in FIG. Retreat to a position above the position where Then, the first feeding means 50 moves to the right in FIG. 1 while being rotated by the motor M5 (see the two-dot chain line position in FIG. 1), and is an unnecessary sheet stuck on the outer peripheral side of the ring frame RF and the outer table 20. S1 is peeled off. After completion of the peeling, the motor M5 is locked and returns to the position indicated by the solid line in FIG. In synchronization with this return, the motor M7 is driven to wind up the unnecessary sheet S1 by the first winding roller 65, and at the same time, the motor M2 of the supply means 12 is driven to support the new adhesive sheet substrate SB. It will be supplied above the means 11. Further, the wafer W integrated with the ring frame RF through the sticking sheet S is transferred to the next process through a transfer means (not shown). Then, a new ring frame RF and wafer W are transferred to the support means 12, and thereafter the same operation is repeated to sequentially perform integration processing. When the adhesive sheet base SB is attached to the ring frame RF and the wafer W, the tip of the cutter blade 34 is attached to the ring by keeping the adhesive sheet base SB positioned on the outer peripheral side of the pressing member 41 in an inclined posture. It is also possible to form the cuts C in the adhesive sheet base material SB without contacting the frame RF.

[Multi-layer aftercut application mode]
As shown in FIG. 6, the multilayer original fabric R <b> 2 is set on the supply unit 12, and the adhesive sheet substrate SB and the release sheet RL are peeled off at the front end position of the peeling unit 52. Then, the lead end of the adhesive sheet substrate SB is fixed to the first winding roller 65 via the first feeding means 50, and the lead end of the release sheet RL is peeled off via the second feeding means 51. Fix to the sheet take-up shaft 67. Moreover, the support means 11 is maintained at the same position as the single-layer aftercut application mode.

  When the power is turned on, the notch detection means 70 does not detect the notch C, so an OFF signal is detected, and the adhesive sheet base material detection means 71 detects the adhesive sheet base material SB (unnecessary sheet S1) and outputs an ON signal. The detection means 72 detects the release sheet RL and outputs an ON signal to the control means 17. Based on the pattern of these signals, the control means 17 causes the currently set original fabric to be the multilayer original fabric R2, and after the adhesive sheet base material SB is attached to the ring frame RF and the wafer W, the adhesive sheet base material. The multi-layer aftercut application mode for forming the cut C in the SB is specified.

  When the control means 17 specifies the multilayer aftercut sticking mode, the control means outputs a signal for executing the multilayer aftercut sticking mode. That is, the operation signal is sent to the support means 11, the supply means 12, the first notch forming means 13, the first and second feeding means 50 and 51, the first unnecessary sheet winding means 55, and the release sheet winding means 57. On the other hand, control is performed so as not to output an operation signal to the second notch forming unit 14, the second unnecessary sheet winding unit 56, and the moving unit 26.

  Since this multilayer aftercut sticking mode is substantially the same as the single layer aftercut sticking mode except that an operation of winding the release sheet RL is added, description of the operation is omitted.

[Multi-layer cut cut pasting mode]
As shown in FIGS. 7 and 8, the multi-layer original fabric R2 is set on the supply means 12, and the lead end of the adhesive sheet substrate SB is fixed to the second winding roller 66 at a position past the nip roller 74. The release sheet RL is fixed to the release sheet take-up shaft 67 via the release means 52 and the second feeding means 51. The support means 11 is maintained at a position indicated by a two-dot chain line in FIG.

  When the power is turned on, the cut detection means 70 does not detect the cut C, so an OFF signal is generated, and the adhesive sheet base material detection means 71 does not detect the adhesive sheet base material SB (unnecessary sheet S1), so an OFF signal is output. The detection means 72 detects the release sheet RL and outputs an ON signal to the control means 17. Based on the pattern of these signals, the control means 17 is provided with a notch C for the adhesive sheet base material SB in the middle of feeding the multilayer original R2 when the original set is the multilayer original R2. The sheet S is formed, and the multilayer immediately preceding cut sticking mode in which the sticking sheet S is peeled off from the release sheet RL and attached to the ring frame RF and the wafer W is specified.

  When the control unit 17 specifies the multiple layer immediately preceding cut pasting mode, the control unit outputs a signal for executing the multiple layer just prior cut pasting mode. That is, an operation signal is sent to the support means 11, the supply means 12, the second notch forming means 14, the second feeding means 51, the second unnecessary sheet winding means 56, the release sheet winding means 57, and the moving means 26. On the other hand, control is performed so that no operation signal is output to the first notch forming unit 13, the first feeding unit 50, and the first unnecessary sheet winding unit 55.

  In this multi-layer immediately preceding cut pasting mode, the pasting operation is performed before the pasting operation is performed. That is, the multi-layer original fabric R2 supplied from the supply unit 12 is fed out by the second feeding unit 51. At this time, the die cut roller 46 forms a cut C in the adhesive sheet substrate SB, and the sticking sheet S is peeled off. After being fed out at the tip of 52 until it is detected by a sensor (not shown), it stops and enters a standby state. At this time, the adhesive sheet base SB outside the sticking sheet S is wound up by the second unnecessary sheet winding means 56 as the unnecessary sheet S1.

  When it is confirmed by a sensor (not shown) that the ring frame RF and the wafer W are placed on the support means 11 by a transfer means (not shown), the support means 11 is moved to the position indicated by the solid line shown in FIG. Moved to. Thereafter, the outer table 20 and the inner table 21 are moved upward by the linear motion motors 24 and 25 and set so that the ring frame RF and the upper surface of the wafer W are located in the same plane.

  Next, the supporting means 11 is conveyed leftward in FIG. 7 by the moving means 26, and the second feeding means 51 is driven to rotate in synchronization with the conveyance, and the sticking sheet S is peeled off at the tip of the peeling means 52. The sheet RL is peeled off, pressed by the press roller 53, and attached to the ring frame RF and the wafer W. At this time, the release sheet RL is taken up by the release sheet take-up means 57, and the unnecessary sheet S1 is taken up by the second unnecessary sheet take-up means 56.

[Multi-layer precut application mode]
As shown in FIG. 9, the multi-layer precut original fabric R <b> 3 in which the adhesive sheet S is temporarily attached to one surface of the release sheet RL at a predetermined interval is set in the supply unit 12, and at a position past the nip roller 74. The lead end of the unnecessary sheet S1 is fixed to the second take-up roller 66, and the release sheet RL is fixed to the release sheet take-up shaft 67 via the release means 52 and the second feeding means 51. The support means 11 is maintained at a position indicated by a two-dot chain line in FIG. The unnecessary sheet S1 in the multi-layer pre-cut original fabric R3 is used to eliminate the pressing scratches and steps caused by the overlapping sheets S in the radial direction in a state where the unnecessary sheet S1 is wound in a roll shape without being present. It serves as a spacer provided.

  When the power is turned on, the cut detection means 70 detects the cut C and outputs an ON signal, and the adhesive sheet base material detection means 71 does not detect the adhesive sheet base material SB (unnecessary sheet S1). The detection means 72 detects the release sheet RL and outputs an ON signal to the control means 17. Based on the pattern of these signals, the control means 17 causes the currently set original fabric to be a multi-layer precut original fabric R3, feeds the multi-layer precut original fabric R3, and releases the adhesive sheet S from the release sheet RL. Thus, the multi-layer precut application mode to be applied to the ring frame RF and the wafer W is specified.

  When the control unit 17 specifies the multi-layer precut application mode, the control unit 17 outputs a signal for executing the multi-layer precut application mode. That is, while the operation signal is output to the support unit 11, the supply unit 12, the second feeding unit 51, the second unnecessary sheet winding unit 56, the release sheet winding unit 57, and the moving unit 26, the first notch Control is performed so as not to output an operation signal to the forming means 13, the second notch forming means 14, the first feeding means 50, and the first unnecessary sheet winding means 55.

  In this multi-layer precut sticking mode, before the sticking operation is performed, the multi-layer precut original fabric R3 is fed by the second feeding means 51, and the sticking sheet S is detected by a sensor (not shown) at the tip of the peeling means 52. Until it stops, it stops and enters the standby state. The subsequent operation is substantially the same as the multilayer immediately preceding cut pasting mode except that the operation of the second incision forming means 14 is not performed, and thus the description of the operation is omitted.

  As described above, in the present embodiment, each of the detection means 70 to 72 detects which of the original fabrics R1 to R3 is applied to the supply means 12, and the paste mode is automatically determined based on the detected signal pattern. Therefore, the sheet sticking apparatus 10 can be provided that can save the setting work by the operator and can stick the sticking sheet S efficiently.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
In other words, the present invention has been illustrated and described mainly with respect to specific embodiments, but without departing from the scope of the technical idea and object of the present invention, the shape, position, or With respect to the arrangement and the like, those skilled in the art can make various changes as necessary.
