Description

  The present invention relates to a laminating apparatus for pasting a film taken out from a roll film to another roll film.

  Conventionally, a technique is generally known in which various functional films arranged on a roll-shaped base material are taken out from the roll-type base material while being tension-controlled, and bonded to another roll for conveyance. ing.

  Furthermore, like patent document 1, the technique of bonding films together is also generally known. For example, as shown in FIGS. 14 and 15, only the functional film 102 is cut in the thickness direction, leaving the separator 101, with respect to the base sheet 103 stretched with a constant tension 110 and supplied in a roll state. Perform a half cut. Then, by sending only the separator 101 at an acute angle on a peeling block (not shown), only the functional film 102 is peeled from the separator 101, and the functional film 102 is adsorbed and fixed by a bonding table (not shown). While the functional film 102 adsorbed and fixed to the bonding table is conveyed by the bonding table, the position of the functional film 102 is adjusted, and the functional film 102 is bonded to the roll of the bonding object.

JP 2013-139108 A

  By the way, in the case of patent document 1, when bonding the functional film 102 to the roll of a bonding target object, alignment adjustment with the functional film 102 and the bonding position of the roll of a bonding target object is performed first. Thereafter, the tip of the suction disk holding the functional film 102 is tilted, and the positional deviation amount between the roll conveyance direction and the vertical direction of the object to be bonded is corrected by a fixed value corresponding to the tilt angle. . Thereafter, the tip of the inclined suction disk is pressed against the roll of the object to be bonded so as to perform the bonding.

  In such a pasting operation, even though alignment adjustment is once performed and high-precision position adjustment is performed, a positional deviation occurs in the subsequent tilt operation, and the correction is performed with a fixed value. The position adjustment with high accuracy is not maintained due to the variation in the tilt angle, and as a result, there is a problem that high-precision pasting cannot be performed on the order of ± 10 μm.

  Accordingly, an object of the present invention is to solve the above-described problem and provide a bonding apparatus capable of high-precision bonding on the order of ± 10 μm.

(Knowledge of the present invention)
First, before explaining the present invention, the reason why bonding at a highly accurate position on the order of ± 10 μm cannot be described.

  When the functional film 102 is attached to the roll 122 of the object to be bonded, first, as shown in FIG. 25A, the position adjustment of the functional film 102 and the position of the roll 122 of the object to be bonded is performed with high accuracy. Yes. Then, as shown to FIG. 25B, the front-end | tip of the suction disk 123 which adsorbs and hold | maintains the functional film 102 is inclined, and as shown to FIG. 25C, the conveyance direction of the roll 122 of a bonding target object and an up-down direction are accompanied with inclination. The amount of displacement is corrected by a fixed value corresponding to the tilt angle (see arrow 124). Then, as shown to FIG. 25D, the front-end | tip of the inclined suction disk 123 is pressed against the roll 122 of a bonding target object as shown by the arrow 125, and it sticks as shown to FIG. 25E.

  In such a pasting operation, although a highly accurate position adjustment is once performed, a positional deviation occurs in the subsequent tilting operation. In addition, since the positional deviation is corrected with a fixed value, if the inclination angle varies due to mechanical wear or manufacturing errors in the inclination angle determination part of the inclination mechanism, the position adjustment with high accuracy is maintained. As a result, there was a problem that high-accuracy pasting was not possible on the order of ± 10 μm.

  Therefore, the present inventors have come up with the invention by conceiving that, if the start position of film-to-film attachment can be determined in a state where the position is adjusted with high accuracy, the film can be bonded according to alignment by roller bonding thereafter. Is. That is, before tilting the first film in a highly accurate position adjusted state, first, the application start end of the first film is brought into contact with the application start end of the application target area of the second film. After fixing the first film, tilt the first film and paste the area after the first film sticking end to the second film. It has been found that can be attached.

  In addition, the present inventors are examining the stress which remains in the functional film 102 before bonding so that more highly accurate bonding can be performed more reliably.

  As described above with reference to FIGS. 14 and 15, in the base material sheet 103 configured such that a functional film 102 such as a sensor base material is laminated on the separator 101 in multiple layers and a roll tension 110 is applied. When a half cut 104 is inserted as shown in FIG. 15 only on the functional film 102, a contracting force 105 acts on the functional film 102. At this time, the stress acting on the functional film 102 is unknown depending on the thickness or material of the functional film 102, and it is difficult to control the stress acting on the functional film 102 only by adjusting the tension 110 of the roll. In addition, by peeling the functional film 102 from the separator 101, it is completely unknown what kind of stress remains in the functional film 102. In such an unknown state, the functional film 102 is adsorbed and held by an adsorption board or the like, and the functional film 102 and the object to be bonded are bonded, so what kind of warpage occurs after bonding. It became completely unknown, and bonding at a highly accurate position on the order of ± 10 μm could not be performed.

  In particular, the pattern formed by photolithography or etching is processed with a predetermined roll tension, and when an unknown stress generated when bonding is applied to the pattern, the upper side of FIG. In contrast to the ideal bonding shown in (a), as shown in the lower side (b), a slight misalignment will occur and bonding will occur, and bonding at a highly accurate position on the order of ± 10 μm will be performed. I could n’t.

  Therefore, the present inventors have come up with the invention by contemplating to temporarily stop or alleviate the adsorption holding in the functional film 102 held by the adsorption board or the like to release the remaining stress. It is a thing.

(Embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.

  The bonding apparatus which can implement the bonding method concerning the 1st Embodiment of this invention is a bonding apparatus which bonds films together as shown in FIG.1 and FIG.3, Comprising: The 1st conveyance part 11, The second transport unit 12, the half cut processing unit 13, the suction holding unit 14, the peeling unit 15, the suction operation control unit 17, the transfer mechanism unit 18, and the pasting unit 19 are configured.

  In this bonding apparatus, as shown in FIG. 2, after the 1st film 1 was carried out (rewinded) from the 1st conveyance part 11 at the 1st conveyance part 11 side, half cut process S11 and adsorption | suction On the other hand, on the second transport unit 12 side, the second film 4 is unloaded from the second transport unit 12 (rewinded), and then separated as necessary. The second film 4 is wound up through the step S21, the adsorption step S22 in the sticking part 19, the alignment step S23 in the sticking part 19, and the sticking process S24.

  The 1st conveyance part 11 conveys the 1st film 1 by which the separator 3 was arrange | positioned at one surface with the fixed roll tension 20 along the conveyance direction of the 1st film 1. FIG. In the first film 1, a large number of first conductive patterns are formed at regular intervals in the longitudinal direction on one side of the long resin film on the separator 3 side and on the other side opposite to the separator 3 side. It is a functional film. For example, it is a film for a sensor substrate in which a kind of electrode and a wiring drawn from the electrode are formed as a conductive pattern. Specifically, as shown in FIGS. 1 and 3, the first transport unit 11 guides the first film 1 rewound from the first film rewinding roller 11 a with a plurality of guide rollers 11 c, After guiding to the half-cut processing unit 13, the suction holding unit 14, and the peeling unit 15, the first film 1 other than the sheet-like piece 2 is wound up by the first film winding roller 11b.

  The second transport unit 12 transports the long second film 4 along the transport direction of the second film 4 with a constant tension. The second film 4 is a functional film in which a large number of second conductive patterns are formed on both surfaces of a long resin film at regular intervals in the longitudinal direction. For example, it is a film for a sensor base material in which two types of electrodes and wirings drawn from the electrodes are formed as a conductive pattern. In addition, the 2nd film 4 may also be peeled before the separator is arrange | positioned on one side and it is conveyed to the sticking part 19. FIG. A sheet-like piece extracted from the second film 4 and the first film 1 by aligning the conductive pattern of the sheet-like piece 2 extracted from the first film 1 with high accuracy with respect to the conductive pattern of the second film 4. It is this sticking device that bonds the piece 2 together. Specifically, as shown in FIGS. 1 and 3, the second transport unit 12 guides the second film 4 unwound from the second film rewinding roller 12 a with a large number of guide rollers 12 c, After the sheet-like piece 2 extracted from the first film 1 of the sticking part 19 is guided to the bonding position 92 with the second film 4, the sheet-like piece 2 is bonded to the second film 4. Thus, the film is wound by the second film winding roller 12b. In the vicinity of the second film rewinding roller 12a, a mechanism 12d capable of detecting the tension of the second film 4 and controlling the tension is disposed (see FIG. 11).

  The half-cut processing unit 13 performs the half-cut process S11, and leaves the separator 3 from the first film 1 and half-cuts only the first film 1 in a predetermined size and shape in the thickness direction, A large number of sheet-like pieces 2, that is, sheet-like pieces 2 are formed. As shown in FIG. 3, the half-cut processing unit 13 is arranged in the vicinity of the first film rewinding roller 11 a and sucks and holds the sheet-like pieces 2 generated by half-cutting by the half-cut unit 7 together with the separator 3. Guided by the guide roller 12c to the part 14 and the peeling part 15.

  The adsorption holding unit 14 and the peeling unit 15 perform the adsorption and peeling step S12.

  As shown in FIG. 3, the suction holding unit 14 is disposed in the vicinity of the peeling unit 15 and on the half-cut processing unit 13 side. The suction holding unit 14 stops the conveyance of the first film 1 intermittently, stops at the suction holding position 91 in the vicinity of the peeling unit 15, and is half-cut on the separator 3, thereby causing the first film 1. The sheet-like piece 2 generated from the above is sucked and held. The suction holding unit 14 has a number of suction holes 41 shown in FIG. 8 and can suck and hold the entire surface of only the sheet-like piece 2 of the first film 1, and each suction hole of the suction disk 42. And a suction mechanism unit 47 such as a vacuum suction device communicating with 41, and the suction operation control unit 17 controls the suction operation (that is, the suction operation) by the suction mechanism unit 47. As shown in FIG. 4, the suction plate 42 is moved up and down along the vertical direction by the lifting device 14b, and can be moved along the transport direction of the first film 1 by the first moving device 14c as shown in FIG. Therefore, the elevating device 14b and the first moving device 14c are disposed below the suction plate 42, and further connected to or supported by the transfer mechanism unit 18 to transfer the transfer mechanism unit 18. Thus, the suction disk 42 can reciprocate between the peeling portion 15, the sheet-like piece 2 of the first film 1, and the laminating device 92 along a direction orthogonal to the conveying direction of the first film 1. The elevating device 14b, the first moving device 14c, and the transfer mechanism unit 18 each use a linear motion device that can adjust its position on the order of ± 10 μm and has little play on the ball screw, for example, an actuator such as a servo motor. A drive device that is configured to reciprocate linearly and that can be positioned with high accuracy is preferable.

  The peeling part 15 is the remainder other than the sheet-like piece 2 of the 1st film 1 formed by half-cutting, guiding the separator 3 and the 1st film 1 along the conveyance direction of the 1st film 1 with the guide plate 15a. The part 1a and the separator 3 are reversed at an acute angle by a blade 16 fixed to the tip of the guide plate 15a, and the sheet-like piece 2 of the first film 1 sucked and held by the suction holding part 14 at the suction holding position 91 is obtained. , Peels smoothly from the separator 3. At this time, as shown in FIG. 5, the first film 1 is transported along the transport direction by the first transport unit 11, and the suction holding unit 14 is also moved along the transport direction of the first film 1 by the first moving device 14c. This peeling operation is performed while moving synchronously at the same speed as the transport speed of one film 1.

  As shown in FIG. 6, the sheet-like piece 2 of the first film 1 peeled from the separator 3 by the peeling operation is sucked and held on the suction disk 14a of the suction holding unit 14 (first suction operation S41 described below). However, in this state, as in the conventional case, in addition to the contracting force 81, forces such as the peeled force 82 and the attracting force 83 act, and an unknown stress remains. This remaining unknown stress can be eliminated by the following operation in the adsorption operation control unit 17.

  The suction operation control unit 17 controls the suction operation by the suction mechanism unit 47 in the suction holding unit 14, thereby sequentially performing the first suction operation S41, the suction control operation S42, and the second suction operation S43. These series of operations are performed between the peeling operation and the end of the transfer operation to the bonding position 92. Therefore, for example, the first suction operation S41 is performed from the start of the peeling operation to the end of the peeling operation, the suction control operation S42 is performed after the peeling operation is completed and before the transfer is started, and the second suction operation S43 is performed from the start of the transfer to the end of the transfer. It can be performed. Alternatively, the first adsorption operation S41 can be performed from the start of the peeling operation to the end of the transfer operation, and the adsorption control operation S42 and the second adsorption operation S43 can be performed in order after the transfer operation is completed.

  In the first suction operation S41, the sheet-like piece 2 of the first film 1 is sucked by all the suction holes 41 of the suction disk 14a.

  As shown in FIG. 7, the suction control operation S42 is performed after the first suction operation S41 so that the suction operation is stopped entirely, loosened, partially stopped, or partially loosened. Do something. By this suction control operation S42, when the sheet-like piece 2 is sucked and held on the suction disk 14a, the unknown stress remaining on the sheet-like piece 2 is released from the sheet-like piece 2. Yes. Therefore, if all the suction holding force by the suction hole 41 for the sheet-like piece 2 is stopped, it can be surely released, but at that time, the sheet-like piece 2 is sucked and held at the beginning of the suction disk 14a by the influence of stress or the like. There is a concern that the position may deviate greatly from the position and deviate from the viewing angle when alignment is recognized. In such a case, the suction holding force is loosened as a whole, or the suction holding force by the remaining suction holes 41 is stopped while maintaining the suction holding force by some of the suction holes 41. Then, the suction holding force by the suction holes 41 of some of all the suction holes 41 is maintained and the suction holding force by the remaining suction holes 41 is lowered and partially loosened. What should I do? In this way, it is possible to prevent the sheet-like piece 2 from being largely displaced from the position where the suction disk 14a is initially sucked and held.

  In this operation, a plurality of suction holes 41 arranged in the suction disk 14a shown in FIG. 8 are divided into a plurality of (for example, six rows) vertical regions 43 as shown in FIG. The suction mechanism control unit 17 may control the suction mechanism unit 47 so that the suction holding force by the holes 41 can be controlled independently. Specifically, if each control valve is disposed in a connecting passage that connects each region 43 with a vacuum suction device and a mechanism for generating a vacuum, and each control valve is controlled to be opened and closed by the adsorption operation control unit 17, each region 43. Operation control such as adsorption maintenance, adsorption stop, and relaxation of each adsorption holding force can be performed.

  The method of dividing the area of the suction hole 41 in the suction disk 14a is not limited to that shown in FIG. 9, but it can be divided into horizontal areas 44 as shown in FIG. 10 (a), or as shown in FIG. 10 (b). It can be divided into a matrix region 45 or a concentric region 46 as shown in FIG. As described above, after the suction hole 41 in the suction disk 14a is divided into a plurality of regions, operation control such as suction maintenance, suction stop, and loosening of the suction holding force is performed for each arbitrary region. While maintaining the suction holding force, operation control such as suction stop or relaxation of the suction holding force in the remaining region may be performed.

  Further, among the remaining areas, the suction operation by the suction mechanism 47 in the suction hole 41 of at least one area is reactivated or reintensified, and then the suction is maintained in the area where the suction operation has been maintained. The suction operation by the mechanism unit 47 may be controlled to stop or relax. In this way, it is possible to release any remaining unknown stress in all regions.

  Thus, for example, the suction mechanism portion in the suction hole 41 in one of the divided regions (for example, the right or left end region in FIG. 9 or the upper or lower end region in FIG. 10A). If the suction operation by the suction mechanism 47 of the remaining area 41 is controlled to be stopped or loosened with the suction holes of the remaining area maintained in the state where the suction operation by 47 is maintained, one end is supported in a state where one end is supported. Residual stress in other areas except the part can be released, and then the other stress can be maintained by holding the other end to stop the suction at one end and releasing the residual stress in the one end. It can be released more smoothly. Similarly, for example, in the state where the suction operation by the suction mechanism unit 47 in the suction hole 41 in the central region (for example, the central region in FIG. 10C) among the divided regions is maintained, If the suction operation by the suction mechanism 47 of the region 41 is controlled so as to be stopped or loosened at the suction hole in the region, the residual stress in other regions other than the central portion is released while the central portion is supported. After that, if the suction of the central portion is stopped while the suction of the central portion is stopped and the residual stress in the central portion is released, the residual stress can be released more smoothly.

  2nd adsorption | suction operation | movement S43 prepares for bonding operation | movement by adsorb | sucking again the sheet-like piece 2 of the 1st film 1 to the adsorption | suction board 14a after the adsorption | suction control operation | movement S42 seems to have lost the residual stress.

  The transfer mechanism unit 18 performs the transfer step S <b> 13 and supports the suction holding unit 14 or is provided integrally with the suction holding unit 14. The transfer mechanism unit 18 moves the suction disk 14 a of the suction holding unit 14 between the peeling unit 15 and the bonding position 92 between the sheet-like piece 2 of the first film 1 and the second film 4 of the bonding unit 19. It is arranged so that it can reciprocate. The suction disk 14a of the suction holding unit 14 that sucks and holds the sheet-like piece 2 of the first film 1 peeled off by the peeling unit 15 is moved in the lateral direction perpendicular to the transport direction of the first film 1, and the second film As shown in FIGS. 11-13, it moves to the downward direction of the sticking part 19 of the bonding position 92 across 4 conveyance directions.

  As shown in FIGS. 11 to 13, the pasting unit 19 cooperates with the suction holding unit 14 to perform the suction step S22, the alignment step S23, and the pasting step S24. The pasting unit 19 includes a second film suction disk 60 that functions as an example of a second film suction holding unit, a position adjusting unit 61, a film pasting start member 62, an elevating unit 63, a tilting unit 64, and a moving device. It comprises so that it may be equipped with. Here, the first moving device 14c functions as an example of the moving device.

  The second film suction plate 60 performs the suction step S22, functions as a suction plate that is disposed at the bonding position 92 and has a number of suction holes connected to a suction mechanism unit 19a such as a vacuum suction device, On the lower surface, an area including the rectangular pasting target area 4a of the second film 4 is sucked and held. Below the second film suction plate 60, the upper surface of the suction plate 14a of the suction holding unit 14 transferred to the bonding position 92 by the transfer mechanism unit 18 is for attachment. It can be placed facing each other.

  The position adjustment unit 61 performs the alignment step S23. At the bonding position 92, the sheet of the first film 1 sucked and held by the suction disk 14a of the suction holding unit 14 performing the second suction operation S43. Position adjustment by the position adjustment unit 61 is performed in a state in which the individual piece 2 and the application target area 4a of the second film 4 sucked and held by the second film suction disk 60 are brought close to each other. At this time, the sheet-like piece 2 of the first film 1 and the second film 4 are preferably in a substantially parallel state from the viewpoint of adjusting the position with high accuracy. As an example, with respect to the bonding position 92, the sheet-like piece 2 and the application target area 4a of the second film 4 are approximately the exact position, respectively, the transfer mechanism 18 and the second film rewinding. The position can be adjusted by using actuators such as servo motors as driving devices such as the roller 12a and the second film winding roller 12b. Therefore, the position adjustment unit 61 performs fine adjustment with high accuracy after the approximate position.

  Here, when the sheet-like piece 2 is a quadrangle, as shown in FIG. 16, the first alignment marks 69 are formed at the four corners, and the corresponding four corners of the quadrangular application target region 4a of the second film 4 are formed. Also, the second alignment mark 70 is formed. As an example, one of the first alignment mark 69 and the second alignment mark 70 is a small black circle point, the other is a circular ring, and the small black circle point enters the circular ring so that alignment adjustment can be performed. Can be set to As an example, a small black dot is a point having a diameter of 1 mm, and a circular ring has an outer diameter of 2 mm. Each of the alignment marks 69 and 70 is not limited to a circle or a circle, but may have various other shapes, for example, a square.

  More specifically, the position adjustment unit 61 includes, for example, four cameras 48, a correction amount calculation unit 66, and a position control unit 67.

  The four cameras 48 are arranged in the suction holding unit 14 so as to be able to pick up images near the four corners of the square sheet-like piece 2 of the first film 1 sucked and held by the suction holding unit 14. Therefore, the four cameras 48 image the first alignment marks 69 at the four corners of the sheet-like piece 2 and the second alignment marks 70 at the four corners of the quadrangular pasting target area 4a of the second film 4 facing them. You can get it. For example, the first alignment mark 69 and the second alignment mark 70 may be simultaneously acquired by each camera 48, or the focal length of each camera 48 may be switched to change the first alignment mark 69 and the second alignment mark. 70 may be acquired.

  The correction amount calculation unit 66 performs image processing based on the images acquired by the four cameras 48, and calculates the amount of positional deviation between the first alignment mark 69 and the second alignment mark 70 at the four corners. Then, correction amounts in two directions orthogonal to each other, that is, the conveyance direction of the second film 4 and the lateral direction orthogonal to the conveyance direction are obtained.

  The position control unit 67 adjusts the position of the suction disk 14 a with the first moving device 14 c and the transfer mechanism unit 18 based on the correction amount obtained by the correction amount calculation unit 66. For example, under the control of the position control unit 67, the first moving device 14c of the suction holding unit 14 adjusts the position along the transport direction of the second film 4, and the transfer mechanism unit 18 is orthogonal to the transport direction of the second film 4. Adjust the position along the horizontal direction. By using actuators capable of high-precision positioning such as servo motors as the driving devices for the first moving device 14c and the transfer mechanism unit 18, high-precision position adjustment on the order of ± 10 μm, that is, the second film 4 It is possible to adjust the position of the conductive pattern of the sheet-like piece 2 with high accuracy with respect to the conductive pattern formed in the above. In this way, highly accurate position adjustment is performed by the position adjustment unit 61.

  The sticking step S24 is performed by the second film suction disk 60, the film sticking start member 62, the elevating part 63, the tilting part 64, and the first moving device 14c.

  The film sticking start member 62 is disposed at the tip 14e on the sticking start side of the suction disk 14a of the suction holding unit 14 and is more than the suction holding surface 14f that sucks and holds the sheet-like piece 2 of the suction disk 14a of the suction holding part 14. The sticking start end 2c of the sheet-like piece 2 of the first film 1 is placed and held at a high position in the height direction.

  Here, the high position in the height direction is a position higher than the suction holding surface 14f by 0.1 mm to 2 mm, for example. If the height exceeds 2 mm, the length of the hypotenuse d3 simply increases, and the pasting error increases. On the other hand, at a high position of less than 0.1 mm, it is difficult to adjust the height to such a numerical height, and even though only the pasting start end portion 2c is desired to be contacted, other portions are also contacted. there is a possibility.

The height of the sticking start end portion 2c of the sheet-like piece 2 has the following relationship. As shown in FIG. 17, when the application start end portion 2 c of the sheet-like piece 2 of the first film 1 is placed and held on the film application start member 62, it is applied from the suction holding surface 14 f to the film application start member 62. In the vicinity of the sticking start end 2c, a right triangle relationship is established when viewed from the side. That is, the oblique side d3 where the sheet-like piece 2 is inclined, the side edge d1 along the suction-holding surface 14f that sucks and holds the lower surface of the sheet-like piece 2 in a region other than the vicinity of the sticking start end 2c, and the suction-holding surface A right triangle is formed by the height d2 indicating the height from 14f to the lower surface of the sticking start end 2c. In this way, when positioning is performed by raising in a state where a right triangle is formed, the portion held on the suction holding surface 14f with the alignment mark and the sticking start end to be brought into contact with the second film 4 Since the height of the portion 2c is different, there is a possibility that the sheet-like piece 2 will be misaligned when pasting, as compared with the case where the sheet-like piece 2 is not inclined but parallel to the second film 4. is there. The error of the positional deviation is a numerical value obtained by subtracting the side d1 from the calculated hypotenuse d3 so that the hypotenuse d3 can be calculated from the side d1 and the height d2. For example, assuming that the side d1 is 6 mm and the height d2 is 1 mm, the hypotenuse d3 is √ (6 ² +1 ² ) = 6.08276 mm, and the hypotenuse d3-side d1 = 6.008276 mm−6 mm = 0.08276 mm. , There is an error of 82 μm. When high accuracy on the order of ± 10 μm is required in actual design, it is considered to be severe for high-precision bonding unless the height d2 is set to 1 mm or less. Therefore, when the height d2 is changed from 1 mm to 0.5 mm by an adjusting mechanism described later, the error can be reduced to within ± 10 μm, that is, the error range can be reduced to 20 μm. It can also be seen that the error decreases as the side d1 is lengthened.

  As an example, the high position in the height direction means, for example, that the height is adjusted by an adjusting mechanism in accordance with the use condition within the range of 0.1 mm to 2 mm, in addition to a fixed value of 0.1 mm to 2 mm. You may make it comprise arbitrarily adjustable. For example, when the material or the material is bent, for example, when the material is too hard, the suction pad makes it difficult to suck, so the distance of the height d2 is increased. Adjustment to the optimum position is necessary with d2. Structurally, if the distance of the height d2 is changed, it is necessary to adjust the length of the hypotenuse d3, so that the height needs to be changed.

  As an example of the film sticking start member 62, as shown in FIG. Although not shown, the suction pad member 65 has a number of suction holes, and has a sticking suction mechanism portion 71 such as a vacuum suction device communicating with the number of suction holes, so that the sheet-like piece 2 of the first film 1 is formed. The sticking start end 2c is sucked and held so as to be placed and held on the upper surface of the sucking pad member 65, and at the start of sticking, the sucking and holding force can be stopped or alleviated by the sticking suction mechanism 71. The suction pad member 65 is not involved in the suction operation in the suction and separation step S12.

  As another example of the film sticking start member 62, as shown in FIG. 18 and the like, the film sticking start member 62 is composed of a sticking roll 68 that is rotatably supported by the suction disk 14a, and sticks the sheet-like piece 2 of the first film 1. The start end 2c may be placed and held.

  The elevating part 63 adsorbs the sheet-like piece 2 adsorbed and held by the adsorbing plate 14 a to the second film 4 adsorbed and held by the second film adsorbing plate 60 at the bonding position 92. The holding unit 14 is moved up and down, and can be shared by the lifting device 14b.

  In the tilting portion 64, the sticking start end portion 2c of the sheet-like piece 2 placed and held by the suction pad unit 65 at the tip 14e in the suction holding portion 14 is sucked by the second film suction disk 60 at the beginning of the sticking start. The suction holding unit 14 is tilted (tilted) so as to come into contact with the held second film 4. Specifically, as shown in FIG. 21 and FIG. 22, the suction disk 14a of the T-shaped suction holding part 14 has a base part 14p that can swing around a tilt fulcrum shaft 14j below the leg part 14h. It is supported by. A locking projection 14k bent downward projects from the rear end of the suction plate 14a, and the locking projection 14k comes into contact with the stopper 14m at the rear of the base portion 14p when tilting, so that the suction plate 14a around the tilt fulcrum shaft 14j The tilt angle is regulated to a predetermined angle. A tilting drive device 14n such as a cylinder is disposed between the rear portion of the base portion 14p and the rear end of the suction plate 14a, and the suction plate 14a is extended and retracted from the cylinder 14n, so that the suction plate 14a is tilted to the tilt fulcrum shaft 14j. It can swing around. The tilt drive device 14n is not limited to a cylinder, and may be a linear motion device that can be adjusted in position on the order of ± 10 μm, is configured using an actuator such as a servo motor, and has little play on the ball screw. In addition, the base part 14p is connected with the raising / lowering apparatus 14b, the 1st moving apparatus 14c, and the transfer mechanism part 18, and it can move to each direction integrally with the suction disk 14a.

  The sticking unit 19 having such a configuration performs the sticking step S24 as follows.

  As shown in FIG. 18, the sticking unit 19 is in a state where the position adjustment unit 61 has adjusted the position, and before the suction holding unit 14 is tilted by the tilting unit 64, the lifting and lowering unit 63 moves the suction holding unit 14 from the position adjustment state. Further rising, the sticking start end 2c of the sheet-like piece 2 placed and held on the film sticking start member 62 of the suction holding part 14 is attached to the second film 4 sucked and held by the second film suction disk 60. Make contact. At this time, a region other than the sticking start end portion 2 c of the sheet-like piece 2 is not in contact with the second film 4.

  Next, as shown in FIG. 19, in a state where the sticking start end 2 c of the sheet-like piece 2 is in contact with the second film 4, the cylinder 14 n of the tilting part 64 is driven to the suction holding part 14 up to a predetermined angle. That is, the suction disk 14a is tilted.

  Next, as shown in FIG. 20, the sticking start end 2 c of the sheet-like piece 2 is in contact with the second film 4 and the suction holding part 14 is tilted to a predetermined angle by the tilting part 64. The part 14 is moved by the first moving device 14c in the sticking direction opposite to the conveying direction of the second film 4, and the region behind the sticking start end 2c of the sheet-like piece 2 is moved to the film sticking start member 62. To the second film 4 with the film sticking start member 62. Thus, when the whole sheet-like piece 2 is stuck on the sticking target area 4a of the second film 4, the suction holding part 14 is lowered by the elevating part 63, and the next sheet-like piece 2 is sucked and held. Thus, the transfer mechanism unit 18 returns to the suction holding position 91 and performs the suction and separation step S12.

  In addition, it is preferable to control each drive device etc. which implement a series of bonding operation | movement shown in FIG. 2 with a bonding control part.

  According to the embodiment, after the sheet-like piece 2 of the first film 1 and the second film 4 are aligned with high accuracy by the position adjustment unit 61, the suction plate 14 a is raised by the elevating unit 63, and the film After the sticking start end 2c of the sheet-like piece 2 of the first film 1 held by the sticking start member 62 is brought into contact with the second film 4, the sheet-like piece 2 is sucked and held while maintaining this contact. The suction plate 14a is tilted by the tilting portion 64, and the suction plate 14a is moved by the first moving device 14c in the direction opposite to the conveying direction of the second film 4 while being in the contact and tilted state. The film sticking start member 62 is attached to the second film 4 while the region behind the sticking start end 2c is sequentially sent to the film sticking start member 62. As a result, since it can paste | paste while maintaining the state aligned with high precision, the bonding in the highly accurate position in a +/- 10micrometer order is attained.

  Further, in the suction operation control unit 17, in the suction holding unit 14, the suction operation is stopped entirely, loosened, partially stopped, or partially loosened after the suction operation. By performing the suction control operation for performing the above, it is possible to bond after releasing the stress of the sheet-like piece 2 held by the suction holding unit 14. For this reason, there is no residual stress in the sheet-like piece 2, and even if it is a film-to-film, the positional displacement due to the expansion and contraction of the sheet does not occur, and the warp after the bonding can be effectively prevented, on the order of ± 10 μm. Bonding at a highly accurate position can be made more reliable, leading to quality improvement.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect.

  For example, in order to release the residual stress, in addition to the stop or relaxation of the suction holding force, a small amount of air or the like may be blown out from the suction hole 41 in addition to the stop of the suction holding force to make it easier to release the residual stress.

  Further, both the suction pad member 65 and the rotatable application roll 68 may be provided as the film application start member 62, and may be used by appropriately replacing them.

  That is, as shown in FIG. 23, the sticking portion 19 is rotatably arranged as a film sticking start member 62 on the upper end surface with a suction pad member 65 that sucks and holds the sticking start end portion of the sheet-like piece 2. A replacement mechanism unit 73 having a pasting roll 68 is provided.

  The replacement mechanism 73 has a sticking position 99A and a retracting position 99B at the tip 14e on the sticking start side of the suction plate 14a, in the vicinity of the end of the suction plate 14a, along the transport direction of the second film 4. The suction pad member moving device 74 is movable between the two. Further, in the replacement mechanism 73, at the tip 14e on the sticking start side of the suction disk 14a, the sticking roll 68 is stuck between the sticking position 98A and the retracted position 98B in the vertical direction near the end of the suction disk 14a. It is arranged to be movable by a roll moving device 75.

  As the film sticking start member 62, the upper end surface has a suction pad member 65 that sucks and holds the sticking start end 2 c of the sheet-like piece 2 of the first film 1, and a sticking roll 68 that is rotatably arranged. ing.

  The positions of the suction pad member 65 and the sticking roll 68 are arranged at the position of the tip 14e on the sticking start side of the suction board 14a so that the suction pad member 65 is placed at the start of sticking and the sticking roll 68 is placed after the sticking is started. Replacement is performed by the replacement mechanism unit 73.

  At the start of sticking, the sticking start end 2c of the sheet-like piece 2 is sucked and held on the suction pad surface of the suction pad member 65, and sticking is started. Then, the suction pad member 65 and the sticking roll 68 are replaced by the replacement mechanism 73. After that, the area behind the sticking start end 2 c of the sheet-like piece 2 is stuck on the second film 4 with the sticking roll 68.

  24A to 24E are diagrams for explaining the operation of the replacement mechanism unit 73.

  FIG. 24A shows a state where the position adjustment unit 61 performs alignment by performing the alignment step S23 using the four-point camera 48 or the like. At this time, the suction pad member 65 is located at the sticking position 99A, and the sticking roll 68 is located at the retracted position 98B.

  Next, in FIG. 24B, the suction holding portion 14 is lifted by the lifting and lowering portion 63, and the sticking start end portion 2 c which is the sheet-like piece 2 sucked and held by the suction disk 14 a and held by the suction pad member 65 is The second film 4 is pressed and contacted. At this time, the suction pad member 65 is located at the sticking position 99A, and the sticking roll 68 is located at the retracted position 98B.

  Next, in FIG. 24C, the suction pad member 65 is moved from the sticking position 99 </ b> A to the retracted position 99 </ b> B by the suction pad member moving device 74 in a state where the sticking start end 2 c of the sheet-like piece 2 is in contact with the second film 4. At the same time, the sticking roll 68 is raised from the retracted position 98B to the sticking position 98A by the sticking roll moving device 75 so that the sticking start end 2c of the sheet-like piece 2 is pressed against the second film 4 by the sticking roll 68. Become. As a result, the suction pad member 65 is located at the retracted position 99B, and the sticking roll 68 is located at the sticking position 98A.

  Next, in FIG. 24D, the suction disk 14a is tilted to a predetermined angle by the tilting portion 64 in a state where the sticking start end portion 2c of the sheet-like piece 2 is in contact with the second film 4 by the sticking roll 68.

  Next, FIG. 24E shows a state in which the first moving device 14c performs the second operation while the sticking start end 2c of the sheet-like piece 2 is in contact with the second film 4 with the sticking roll 68 and the suction disk 14a is tilted. The adhering plate 14a is moved along the direction opposite to the conveying direction of the film 4, and the adhering roll 68 rotates while sequentially feeding the area behind the adhering start end 2c of the sheet-like piece 2 to the adhering roll 68. This is applied to the second film 4 while applying a pressing force. The first moving device 14c moves while interlocking the movement of the position shift in the tilting operation so that the contact position does not change. At this time, the suction pad member 65 is located at the retracted position 99B, and the sticking roll 68 is located at the sticking position 98A.

  Such a configuration has the following advantages. That is, first, the reason why the suction pad member 65 is arranged at the end of the suction disk 14a instead of the sticking roll 68 is that the end of the sheet-like piece 2 is sucked to curl the sheet-like piece 2. It is because it can suppress. Further, in the case of contact by the sticking roll 68, the sticking can be performed smoothly, but there is a risk that an appearance defect (such as turning up) may occur due to the curl of the end of the sheet-like piece 2. Therefore, since both the sticking roll 68 and the suction pad member 65 are provided, and both members cannot be placed at the same place mechanically, the sticking roll 68 and the sticking roll 68 Each advantage with the suction pad member 65 can be enjoyed.

  The present invention is not limited to the above-described embodiment. For example, the second film 4 also has a function in which a large number of second conductive patterns are formed on one side of a long resin film at regular intervals in the longitudinal direction. It may be a film. Further, one of the first film 1 and the second film 4 may be a decorative film in which a large number of pattern patterns are formed at regular intervals in the longitudinal direction. Furthermore, it is applicable also to bonding of a film-like organic LED and a functional film or a decorative film.

  In addition, it can be made to show the effect which each has by combining arbitrary embodiment or modification of the said various embodiment or modification suitably. In addition, combinations of the embodiments, combinations of the examples, or combinations of the embodiments and examples are possible, and combinations of features in different embodiments or examples are also possible.

  The bonding apparatus according to the present invention can be bonded at a highly accurate position on the order of ± 10 μm, and is useful when a film taken out from a roll film is bonded to another roll film.
