It is a figure which shows the laminating apparatus (web bonding apparatus) which concerns on one Embodiment of this invention.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view showing a laminating apparatus (web bonding apparatus) 1 according to an embodiment of the present invention. A laminating apparatus 1 shown in FIG. 1 is for manufacturing electronic components such as a flexible substrate and a film sensor.

  The laminating apparatus 1 of the present embodiment includes a first transport device 15, a second transport device 25, a laser processing device 30, a first tension management device 27, a first sheet peeling device 50, and a second tension management device. 31, a second sheet peeling device 32, a CCD camera 35, and a control unit 90.

  The 1st conveyance apparatus 15 is a vacuum conveyor belt which conveys the sheet | seat 11 in which the several pattern 111 was formed to the bonding position 100 through the 1st conveyance path | route 110. FIG. The first conveyance path 110 is a movement path of the sheet 11 that conveys the sheet 11 to the bonding position 100.

  For example, the sheet 11 is formed by forming a pattern 111 on the base material 112 by an etching process or the like in an upstream process before reaching the laminating apparatus 1. In the present embodiment, the plurality of sheets 11 are conveyed to the bonding position 100 at a predetermined speed by the first conveying device 15. The sheet 11 may be transported in one row in the transport direction or may be transported in multiple rows.

  The first conveying device 15 is a vacuum conveyor belt, conveys the sheet 11 while sucking it, and prevents displacement.

  The second transport device 25 transports the masking material 20 to the bonding position 100 through the second transport path 120. The second conveyance path 120 is a path different from the first conveyance path 110 and is a movement path of the masking material 20 that joins the bonding position 100 of the first conveyance path 110. A laminating roller 26 is disposed on the bonding position 100 side of the second conveying path 120, and the masking material 20 is conveyed along the second conveying path 120 at a predetermined speed by the rotational driving of the laminating roller 26.

  The masking material 20 extends in a band shape and is continuously supplied to the bonding position 100. A release sheet 21 is bonded to the masking material 20, and the masking material 20 and the release sheet 21 are integrally conveyed on the second conveyance path 120 until reaching a later-described release position 102, and the release sheet 21 is released at the release position 102. Is peeled off and then sent to the bonding position 100.

  The laser processing apparatus 30 performs a cutting process with a laser on the masking material 20 in a state where the release sheet 21 is adhered. The laser processing apparatus 30 is a galvano type. In addition, the laser which processes the masking material 20 is not necessarily limited to a galvano type | mold, It can change suitably according to a situation.

  The laser irradiation position 101 is set on the upstream side of the bonding position 100 in the second transport path 120. The laser processing apparatus 30 performs laser processing by irradiating the masking material 20 with laser from the opposite side of the masking material 20 to which the release sheet 21 is bonded.

  In the laser processing, the masking material 20 is irradiated with a laser so as to cut out a predetermined shape. The processing portion for processing the laser of the masking material 20 is set so that the processing portion is located at a predetermined portion corresponding to the pattern 111 of the sheet 11 when the masking material 20 is bonded to the sheet 11.

  In the laser processing of the present embodiment, laser processing is performed at a depth corresponding to the thickness of the masking material 20, and the release sheet 21 is not cut.

  The first sheet peeling apparatus 50 peels the release sheet 21 from the masking material 20 before the masking material 20 reaches the bonding position 100. The peeling position 102 where the peeling sheet 21 is peeled is set on the downstream side of the irradiation position 101 and the upstream side of the bonding position 100 in the second transport path 120, and is a masking material before being bonded to the sheet 11. The release sheet 21 is peeled from 20.

  The release sheet 21 peeled off at the peeling position 102 is sent to the first sheet peeling apparatus 50 side. In the laser processing performed on the upstream side of the peeling position 102, the laser depth is set so that only the portion of the masking material 20 is cut, and the peeling sheet 21 is not cut. Therefore, an unnecessary portion of the masking material 20 cut out by laser processing is separated from the masking material 20 while being adhered to the release sheet 21 to be peeled off at the peeling position 102. That is, the unnecessary part cut | disconnected by laser processing is removed with the peeling sheet 21 in the peeling position 102, and has the structure which does not reach the bonding position 100. FIG.

  The first tension management device 27 manages the tension of the masking material 20 conveyed through the second conveyance path 120. The tension applied to the masking material 20 is set according to the material and thickness of the masking material 20 and the release sheet 21. The masking material 20 is sent to the downstream side in a state where the tension is appropriately managed by the first tension management device 27. The tension of the masking material 20 is detected by a tension detection unit such as a load cell (not shown), and the control unit 90 described later performs tension management.

  The CCD camera 35 is an image detection unit that acquires image information of the sheet 11 flowing through the first conveyance path 110. The imaging position 103 where the CCD camera 35 acquires image information is set on the upstream side of the bonding position 100 in the first transport path 110.

  The control unit 90 is a computer that performs various controls of the laminating apparatus 1. The controller 90 adjusts the conveyance speed of the sheet 11, adjusts the suction force of the first conveyance device 15, adjusts the conveyance speed of the masking material 20, manages the tension of the masking material 20, and controls the laser processing of the laser processing device 30. Is done.

  In the laser processing control, the masking material 20 transported along the second transport path 120 is irradiated with a laser to perform cutting processing for cutting out a predetermined shape. The position where the masking material 20 is to be cut needs to match the position of the sheet 11 and the position of the pattern 111 formed on the sheet 11 when bonded to the sheet 11. Therefore, the timing for irradiating the laser is set in accordance with the position of the sheet 11 conveyed along the first conveyance path 110. The sheet 11 is conveyed at a preset conveyance speed, and the current position of the sheet 11 can be estimated from the conveyance speed and the elapsed time. However, a conveyance error may occur in the conveyance of the sheet 11. In the present embodiment, the control unit 90 detects a transport error based on the image information acquired by the CCD camera 35, and the laser irradiation timing is corrected based on the transport error. The masking material 20 may mask a part of the pattern 11 or may mask the whole. Thus, the masking method of the masking material 20 can employ a suitable one depending on the circumstances.

  The control unit 90 of the present embodiment stores a reference shape for specifying the actual position of the sheet 11. The reference shape may be the sheet 11 itself, a part of the pattern 111 formed on the sheet 11, or a shape having characteristics formed on the outside of the pattern 111. The reference shape is a shape, a pattern, a color, or a combination thereof having a characteristic point for visually comparing with another shape at a position that falls within the imaging range of the CCD camera 35.

  An example of detecting a transport error will be described. The control unit 90 extracts a reference shape from the image information acquired by the CCD camera 35, and calculates a transport error based on the position of the reference shape. The conveyance error is calculated from the difference between the position of the reference shape included in the image information captured by the CCD camera 35 and the assumed position of the reference shape assumed from the conveyance speed, and the calculated conveyance error is the timing of laser irradiation. To reflect. For example, when the position of the reference shape of the image information is located upstream of the assumed position in the first conveyance path 110, the conveyance of the sheet 11 is delayed, so laser irradiation is performed in accordance with the delay amount. Delay the timing. On the other hand, when the position of the reference shape is located downstream of the assumed position in the first conveyance path 110, the conveyance of the sheet 11 is accelerated, and the timing of performing laser irradiation in accordance with the accelerated amount. Speed up. In addition, the detection of the conveyance error based on the image information by the control unit 90 is not limited to this method, and various methods can be employed.

  The masking material 20 that has been subjected to laser processing is peeled off from the release sheet 21 at the release position 102 by the first sheet peeling device 50, is reversed by the laminating roller 26 with the adhesive surface exposed, and is conveyed to the bonding position 100. The At the bonding position 100 where the first conveyance path 110 and the second conveyance path 120 merge, the masking material 20 is peeled off on the sheet 11 (the surface on which the pattern 111 of the sheet 11 is formed) conveyed by the first conveyance device 15. The surfaces from which the sheet 21 has been peeled are bonded together to be integrated, and in this state, the sheet 21 is conveyed to a downstream process. A plurality of sheets 11 are bonded to the masking material 20 as a web.

  Laminate rolls 28 and 29, a second tension management device 31, and a second sheet peeling device 32 are disposed on the downstream side of the bonding position 100. A masking material 40 that fills the gap between the sheets 11 in the conveying direction is further bonded. The masking material 40 is sent to the bonding position 501 while the tension is managed by the second tension management device 31. The second sheet peeling device 32 peels the release sheet 41 on the upstream side of the bonding position 501. As a result, a roll (web) 500 is formed between the masking material 20 and the masking material 40 in which a plurality of sheets 11 are arranged in the transport direction. The roll 500 is cut to a predetermined size, and an electronic component having a laminate is manufactured.

According to the above embodiment, the following effects can be obtained.
A laminating apparatus (web bonding apparatus) 1 includes a first conveying apparatus 15 that conveys a plurality of sheets 11 to a bonding position 100 through a first conveying path 110 at intervals in the conveying direction, and a masking material (web) 20. A second conveyance device 25 that conveys to the bonding position 100 through the second conveyance path 120 and a CCD camera (image detection unit) 35 that acquires image information of the sheet 11 on the upstream side of the bonding position 100 in the first conveyance path 110.

Based on the laser processing step of performing laser processing on the masking material 20 upstream of the position 100 and the image information acquired in the image detection step, the conveyance error of the sheet 11 is acquired, and the masking material 20 is determined based on the conveyance error. Adjusting the laser processing with respect to.

  As a result, the actual position of the sheet 11 (pattern 111 formed on the sheet 11) is reflected in the laser processing on the masking material 20, so that the laser processing can be performed with high accuracy, and a plurality of sheets are provided on the masking material 20. 11 can be performed with high accuracy. Moreover, since the some sheet | seat 11 can be correctly bonded together to the masking material 20 which was processed, the some sheet | seat 11 can be handled as a roll (web). As a result, it becomes easy to continuously perform the cutting operation on the roll in which the masking material 20 is bonded to the plurality of sheets 11, and the working time is shortened compared to the process of bonding the masking material for each sheet of the sheet. The working efficiency can be effectively improved.
