[How to cut the top film 200 and the bottom film 300]
FIG. 3 is a schematic diagram showing a method of cutting the upper film 200 and the lower film 300.
In FIG. 3, the work 100 is shifted by y [mm] from the center in the direction (width direction) intersecting the transport direction, as shown as "(1) Work 100 with deviation from the reference position and reference posture". At the same time, it is in a state in which it is shifted (rotated) by θ [degrees] in the plane direction from the posture facing directly in the conveyance direction.

Here, in the laminator 1 according to the present embodiment, it is not necessary to precisely position the work 100, and the work 100 is moved from the reference position by the camera 20 at a position before being loaded onto the upper laminating roll 70A and the lower laminating roll 70B. The deviation from the reference posture and the deviation from the reference posture are detected.
That is, based on the image of the workpiece 100 taken by the camera 20, the control unit 90 determines the amount of deviation y [mm] from the center in the direction intersecting the transport direction (width direction) and the surface from the orientation directly facing the transport direction. The rotation angle θ [degrees] in the direction is detected.

In FIG. 3, as shown in "(2) Cutting example of the top film 200", the top film 200 is cut at a position shifted by y [mm] from the center in the width direction of the top film 200 by the top film cutting section 40. Then, it is rotated by θ [degrees] in the plane direction from a position directly facing the transport direction, and cut into a shape to be attached to the workpiece 100 (substrate). Note that the portion other than the part to be attached to the workpiece 100 (substrate) is handled as a continuous body, as shown in "(3) Example of margin of top film 200", and is wound up by a margin take-up roller (not shown). .

Similarly, in FIG. 3, as shown in "(4) Cutting example of the lower film 300", the lower film 300 is shifted by y [mm] from the center in the width direction of the lower film 300 by the lower film cutting section 60. The workpiece 100 (substrate) is cut into a shape to be attached to the workpiece 100 (substrate) by rotating it by θ [degrees] in the plane direction from a position directly facing the conveyance direction. However, in the lower film 300, the position and rotation angle are defined by coordinates in a mirror image relationship with the upper film 200. The portion other than the portion to be attached to the workpiece 100 (substrate) is handled as a continuous body, as shown in "(5) Example of margin of bottom film 300", and is taken up by a margin take-up roller (not shown). .

The upper film 200 and the lower film 300 cut in this manner are conveyed to the positions of the upper laminating roll 70A and the lower laminating roll 70B, with the phases of the work 100 and the conveying direction (x direction) matching.
Then, the laminated portion of the upper film 200 peeled off by the upper film peeling member 34 is temporarily attached to the upper surface of the workpiece 100, and the laminated portion of the lower film 300 peeled off by the lower film peeling member 54 is temporarily attached to the upper surface of the workpiece 100. , is temporarily attached to the lower surface of the workpiece 100.

With the upper film 200 and the lower film 300 temporarily attached, the work 100 is conveyed between the upper laminating roll 70A and the lower laminating roll 70B, and is pressed from above and below to form "(6) Laminated work 100". As shown, a workpiece 100 is formed by laminating an upper film 200 and a lower film 300.

[Functional configuration of control unit 90]
Next, the functional configuration of the control section 90 will be explained.
FIG. 4 is a block diagram showing the functional configuration formed in the control section 90.
When the control unit 90 executes a program for controlling the laminator 1, the functional configuration includes a work conveyance control unit 91, a work state detection unit 92, a top film conveyance control unit 93, and a top film cutting control unit. 94, a lower film conveyance control section 95, and a lower film cutting control section 96 are formed.

The workpiece conveyance control unit 91 controls the conveyance of the workpiece 100 to be processed. Specifically, the workpiece conveyance control section 91 controls the loading section 10, the upper laminating roll 70A, the lower laminating roll 70B, and the discharging section 80, and conveys the workpiece 100 at a predetermined timing and speed.

The work state detection unit 92 takes an image of the work 100 before being laminated by the upper laminating roll 70A and the lower laminating roll 70B. Then, the work state detection unit 92 detects the deviation y [mm] of the position of the work 100 from the center in the direction intersecting the transport direction (width direction), and the in-plane direction of the work 100 from the position directly facing the transport direction. Detect the deviation (rotation angle) θ [degrees].

The top film transport control unit 93 controls actuators that rotate the rotation shafts of the supply roller 30A and take-up roller 30B of the top film supply unit 30, and transports the top film 200 at a predetermined timing and speed.
The top film cutting control section 94 cuts the top film 200 at a position and orientation corresponding to the deviation of the work 100 from the reference position and orientation based on the detection result of the work state detection section 92 . Specifically, the top film cutting control unit 94 rotates the top film 200 by θ [degrees] in the plane direction from a position directly facing the conveyance direction to a position y [mm] from the reference position (center in the width direction) on the top film 200. In this state, the top film 200 is cut into a predetermined shape to be attached to the top surface of the workpiece 100.

The lower film conveyance control unit 95 controls actuators that rotate the rotation shafts of the supply roller 50A and the take-up roller 50B of the lower film supply unit 50, and conveys the lower film 300 at a predetermined timing and speed.
The lower film cutting control section 96 cuts the lower film 300 at a position and orientation corresponding to the deviation of the work 100 from the reference position and orientation based on the detection result of the work state detection section 92 . Specifically, the lower film cutting control unit 96 rotates the lower film 300 by θ [degrees] in the surface direction from a position directly facing the conveyance direction to a position y [mm] from the reference position (center in the width direction) on the lower film 300. In this state, the lower film 300 is cut into a predetermined shape to be attached to the upper surface of the workpiece 100. In the lower film cutting control section 96, the cutting position and rotation angle of the lower film 300 are defined by coordinates that are mirror images of the position and rotation angle in the upper film cutting control section 94 (that is, coordinates that are horizontally reversed).

[motion]
Next, the operation of the laminator 1 will be explained.
FIG. 5 is a flowchart showing the flow of the pasting process executed by the laminator 1.
The pasting process is a process by which the laminator 1 laminates the top film 200 and the bottom film 300 onto the workpiece 100.
When the pasting process is started, in step S1, the control unit 90 causes the input unit 10 to transport the work 100 to a position in front of the upper laminating roll 70A and the lower laminating roll 70B (supplying the work 100).

In step S2, the control unit 90 photographs the supplied workpiece 100 with the camera 20.
In step S3, the control unit 90 determines the deviation state of the work 100 (that is, the deviation y [mm] from the reference position and the deviation (rotation angle) θ [degrees] from the reference posture) based on the photographed image of the work 100. ]) is detected.
In step S4, the control unit 90 causes the top film cutting unit 40 to cut the top film 200 in accordance with the deviation of the work 100 from the reference position and from the reference posture. Further, the control unit 90 causes the lower film cutting unit 60 to cut (precut) the lower film 300 in accordance with the deviation of the work 100 from the reference position and from the reference posture.

In step S5, the control unit 90 causes the input unit 10 to transport the workpiece 100 between the upper lamination roll 70A and the lower lamination roll 70B, and causes the upper film supply unit 30 and the lower film supply unit 50 to transport the work 100 to the upper film 200. And the lower film 300 is conveyed in phase with the workpiece 100. As a result, the upper film 200 and the lower film 300, which have been cut in advance according to the deviation state of the workpiece 100 (deviation from the reference position and deviation from the reference posture), are laminated in an arrangement that matches the deviation state of the workpiece 100. Injected.

In step S6, the control unit 90 rotates the upper laminating roll 70A and the lower laminating roll 70B to laminate the upper film 200 and the lower film 300 on the upper and lower surfaces of the workpiece 100.
In step S7, the control unit 90 causes the discharge unit 80 to discharge the workpiece 100 on which the upper film 200 and the lower film 300 are laminated, and transfers it to a subsequent process.

As described above, the laminator 1 according to the present embodiment captures an image of the work 100 and detects the deviation of the work 100 from the reference position and orientation prior to the lamination process. Then, the laminator 1 cuts (pre-cuts) the upper film 200 and the lower film 300 in accordance with the detected deviation from the reference position and reference orientation. Further, the laminator 1 aligns the phases of the workpiece 100, the upper film 200, and the lower film 300, and then inputs them into the lamination process. At this time, the upper film 200 and the lower film 300, which have been cut in advance according to the deviation state of the work 100 (deviation from the reference position and deviation from the reference posture), are peeled off from the base material and the work 100 is adjusted to the deviation state. It is temporarily attached to the workpiece 100 in a suitable arrangement. After that, the workpiece 100, the precut upper film 200, and the lower film 300 are pressed by the upper laminating roll 70A and the lower laminating roll 70B, and the upper film 200 and the lower film 300 are laminated on the upper and lower surfaces of the workpiece 100. .

Therefore, when attaching a film cut to match the shape of the work 100, there is no need to accurately position the work 100. Further, since the film can be cut according to the position and orientation of the workpiece 100, there is no need to cut the film into an expected shape with high precision.
Therefore, the cut film can be easily attached to the workpiece 100.
In particular, when a film made of a continuous body is sequentially cut and pasted according to the shape of the workpiece 100 that is continuously supplied, even in situations where the position and orientation of the workpiece 100 vary, the film can be cut into a predetermined shape. can be easily attached to the workpiece 100.

Under such a configuration, the laminator 1 shown in FIG. 6 captures an image of the work 100 and detects a deviation of the work 100 from the reference position and orientation prior to the lamination process. Then, the laminator 1 cuts (pre-cuts) the top film 200 in accordance with the detected deviation from the reference position and reference posture. Further, the laminator 1 aligns the phases of the workpiece 100 and the top film 200, and then inputs the workpiece 100 and the top film 200 into the lamination process. At this time, the top film 200, which has been cut in advance according to the deviation state of the workpiece 100 (deviation from the reference position and deviation from the reference posture), is temporarily attached to the workpiece 100 in an arrangement that matches the deviation state of the workpiece 100. . Thereafter, the workpiece 100 and the precut upper film 200 are pressed by the upper laminating roll 70A, and the upper film 200 is laminated on the upper surface of the workpiece 100.
Therefore, when attaching a film cut to match the shape of the work 100 to one side of the work 100, there is no need to accurately position the work 100. Further, since the film can be cut according to the position and orientation of the workpiece 100, there is no need to cut the film into an expected shape with high precision.
Therefore, the cut film can be easily attached to the workpiece 100.

Further, the laminator 1 aligns the phases of the workpiece 100 and the top film 200, and then inputs the workpiece 100 and the top film 200 into the lamination process. At this time, the top film 200, which has been cut in advance according to the deviation state of the workpiece 100 (deviation from the reference position and deviation from the reference posture), is temporarily attached to the workpiece 100 in an arrangement that matches the deviation state of the workpiece 100. . Thereafter, the workpiece 100 and the precut upper film 200 are pressed by the upper laminating roll 70A and the lower laminating roll 70B, and the workpiece 100 is laminated by the upper film 200. Temporary attachment and lamination are similarly performed on the lower film 200 as well.
