The drive rollers 27 and 31 are rotatably provided via rotation motors DM1 and DM2 as drive devices.

  The cutting means 15 is disposed on the belt-like sheet WS side of the raw fabric RS to be fed out, and the die cut roller 36 as a cutter portion provided rotatably by a rotation motor DM3 as a driving device, and the raw fabric RS in between. A platen roller 37 serving as a pressure receiving portion that receives the pressing force of the die cut roller 36 and is opposed to the die cut roller 36, and the die cut roller 36 is moved in the left-right direction so that the relative distance between the die cut roller 36 and the platen roller 37 is increased. Adjustable adjustment means 38 and contact detection means 39 capable of detecting contact between the die cut roller 36 and the platen roller 37 are provided. The platen roller 37 is rotatably provided in conjunction with the die cut roller 36 by a mechanism (not shown).

  The die cut roller 36 is supported by the adjusting means 38 via the bracket 41 together with the rotation motor DM3. The die-cut roller 36 includes a closed-loop cutting blade 40 projecting from the outer peripheral surface, and is provided so that a substantially circular cut CU that is larger than the inner diameter dimension of the ring frame RF and smaller than the outer dimension dimension can be formed on the belt-like sheet WS. It has been. Further, the cutting blade 40 is provided, for example, over a range of 270 ° in the rotational direction of the die cut roller 36, the front end in the rotational direction is denoted by reference numeral 40a in FIG. 1, and the rear end is denoted by reference numeral 40b in the same figure. Show. The height of the cutting blade 40 is set to 450 μm.

  The adjusting means 38 includes an output shaft 38A connected to the bracket 41, and functions as a linear motion motor as a drive device that can move the output shaft 38A in the left-right direction, and in the direction of arrow R1 or arrow R1 in FIG.

  The contact detection means 39 includes a sensor 45 that can detect that the platen roller 37 and the cutting blade 40 are in contact with each other by being in contact with each other. Thereby, the state where the platen roller 37 and the cutting blade 40 are insulated by the presence of the original fabric RS can be determined as a non-contact state, and the state where the platen roller 37 and the cutting blade 40 are electrically connected is in contact. It can be judged as a state.

  Here, the cutting means 15 is provided with energy applying means (not shown), and the cutting CU can be formed while applying energy to the raw fabric RS by the energy applying means. Examples of the energy applying means include a coil heater built in at least one of the die-cut roller 36 and the platen roller 37, and a blower that blows hot air from a position away from the rollers 36 and 37 to the formation position of the cut CU. An irradiation device that irradiates energy rays such as a vessel, ultraviolet rays, infrared rays, and microwaves.

  The winding means 16 is wound around the unnecessary sheet US after the cutting means 15 forms the cut CU, and peels off the unnecessary sheet US from the release sheet RL. A take-up shaft 51 for taking up the unnecessary sheet US is provided. The take-up shaft 51 is rotatably provided via a rotation motor DM4 as a drive device, and can take up the unnecessary sheet US with a predetermined torque.

  Next, a method for applying the adhesive sheet AS in the present embodiment will be described.

  First, the raw fabric RS supported by the support shaft 25 is passed between the first drive roller 27 and the first pinch roller 28 and between the die cut roller 36 and the platen roller 37. Then, the strip-like sheet WS is peeled from the release sheet RL, and the strip-like sheet WS is wound around the peeling roller 50, and then the lead end is fixed to the winding shaft 51. Further, the release sheet RL is folded at the tip of the release plate 18 to pass between the second drive roller 31 and the second pinch roller 32, and its lead end is fixed to the winding shaft 34. In the present embodiment, the belt-like sheet WS has a thickness of 100 μm, and the release sheet RL has a thickness of 25 μm. Further, the relative distance between the die cut roller 36 and the platen roller 37 is adjusted by the adjusting means 38. In this embodiment, when the cutting blade 40 forms the cutting CU, the distance between the apex of the cutting blade 40 and the outer peripheral surface of the platen roller 37 is set to 10 μm. In the present embodiment, as shown in FIG. 1, the center of the area where the cutting blade 40 is not formed in the rotation direction of the die cut roller 36 is set as the start position St of the die cut roller 36, and the start position St is set to the platen roller 37. The rotation of the die cut roller 36 is stopped in the state of approaching again.

  Then, when the raw fabric RS is fed out by interlocking the rotation motors DM1 to DM4, the cutting blade 40 forms a cut CU from the base sheet BS side to the release sheet RL side, and the strip sheet WS is cut. It is divided into an adhesive sheet AS inside the CU and an unnecessary sheet US outside the cut CU. In the process of forming the adhesive sheet AS, for example, when the cut CU partially or entirely penetrates the original fabric due to some influence, the contact detection unit 39 contacts the platen roller 37 and the cutting blade 40. And the detection signal is output to control means such as a computer or sequencer (not shown). Upon receipt of the detection signal from the contact detection means 39, the control means stops the operation of the sheet sticking apparatus 10 to an emergency stop state or notifies the operator or the like by a notification means such as sound or light. It can be carried out. Here, the control means (not shown) measures the duration of the detection signal input from the contact detection means 39 while forming one adhesive sheet AS by an internal timer, and if the duration is within a predetermined time, You may provide the time cancellation means which does not perform emergency response, such as an emergency stop. Further, a control means (not shown) counts the number of detection signals input from the contact detection means 39 while forming one adhesive sheet AS by an internal counter. If the number of inputs is within a predetermined number, an emergency stop is performed. It is also possible to provide a count canceling unit that does not perform emergency response such as The count canceling means preferably gives priority to the time canceling means.

  After the formation of the cut CU, the unrolled sheet RS is peeled off from the release sheet RL by the peeling roller 50, and the unnecessary sheet US is wound around the take-up shaft 51. At this time, since the interval between the cutting blade 40 and the platen roller 37 is set to such an extent that they do not come into contact with each other, the adhesive sheet AS is easily separated from the unnecessary sheet US, and the adhesive sheet AS together with the unnecessary sheet US is in the direction of the winding shaft 51. There is no going up together. Next, when the adhesive sheet AS of the original web RS on which the unnecessary sheet US is wound is peeled off from the front end of the release plate 18 by a predetermined amount, the front end of the adhesive sheet AS is detected by a sensor (not shown) and stopped. It becomes a state. At this time, since the cut CU surely enters the release sheet RL, the leading end of the adhesive sheet AS in the feed direction is reliably released from the release sheet RL, and is wound in the direction of the second drive roller 31 together with the release sheet RL. There is no such thing. In the standby state, as shown in FIG. 1, the die cut roller 36 has the start position St opposed to the platen roller 37, and the die cut roller 36 and The position of the platen roller 37 can be displaced in the vertical direction. According to this, the intervals between the adhesive sheets AS can be arbitrarily adjusted, and the positions thereof can be changed in the vertical direction according to the length in the feeding direction of the adhesive sheet AS. Thereafter, the ring complaint RF and the wafer WF are placed on the table 11 via a transfer means (not shown) and are sucked and held. Next, the table 11 is conveyed below the peeling plate 18 from the right side to the left side via the linear motor 12. When the table 11 is detected at a predetermined position by a sensor (not shown), the first and second drive rollers 27 and 31 are rotated in synchronism with the conveyance of the table 11 to feed out the original fabric RS, and the leading edge of the peeling plate 18 The adhesive sheet AS is peeled off. Then, the peeled adhesive sheet AS receives a pressing force by the pressing roller 19 and is attached to each upper surface of the ring claim RF and the wafer WF, and the wafer WF and the ring claim RF are integrated through the adhesive sheet AS. At this time, since the release sheet RL portion corresponding to the leading end portion in the feeding direction of the adhesive sheet AS is surely released from the adhesive sheet AS, the adhesive sheet AS with the release sheet RL portion attached thereto is affixed to the adherend. There is no such thing.

  Therefore, according to such an embodiment, since the contact between the cutting blade 40 and the platen roller 37 can be detected, even if the cutting CU partially or entirely penetrates the raw material RS. , It can be detected and emergency response such as emergency stop can be taken, and the adhesive sheet AS and the release sheet RL corresponding to the adhesive sheet AS fall off from the original RS, or the adhesive with the release sheet RL attached. It is possible to suppress the sticking failure of the adhesive sheet AS such that the sheet AS is stuck to the adherend.

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.

Then, in a state where the feeding of the raw fabric RS is stopped, the adjusting means 38 is driven, and the die cutting roller 36 is moved in the right direction to bring the cutting blade 40 and the platen roller 37 closer to each other. When the tip 40a of the cutting blade 40 and the contact portion 44 come into contact, the contact detection means 39 detects the contact and outputs a detection signal to a control means (not shown). The control means receives the detection signal from the contact detection means 39, and moves the die cut roller 36 to the adjustment means 38, for example, 10 μm leftward to send a command. From this state, it is also possible to configure the cut CU by feeding the original fabric RS in conjunction with the rotation motors DM1 to DM4.

Thereafter, after the apex of the cutting blade 40 is brought into a position where it does not come into contact with the original fabric RS by the adjusting means 38, the original fabric RS is fed out by interlocking the rotation motors DM1 to DM4 to form the cut CU. When forming the cut CU, the control means performs control so that the tip 40a of the cutting blade 40 is positioned 10 μm leftward with respect to the platen roller 37 based on the previously stored contact position. The operation of forming such a test cut TC may be performed every time one adhesive sheet AS is formed, or may be performed every time a plurality of adhesive sheets AS are formed, or the die cut roller 36 or the cutting may be performed. Each time the blade 40 is replaced, it may be performed once or a plurality of times.
