Description

The present invention, by transferring the optical film to the panel, an optical science film sticking system that produce optical products optical film is adhered to the surface.

Conventionally, there has been an optical film affixing device for producing an optical film conjugate as an optical product by transferring (adhering) an optical film to a panel using a transfer body (see, for example, Patent Document 1). Optical products (optical film conjugates) manufactured by an optical film affixing device have been used in relatively large display devices such as televisions. Further, as a technique related to an optical film, there is an apparatus having a half-cut mechanism for half-cutting an optical film of a sheet member having an optical film bonded to the surface (see, for example, Patent Document 2).

The conventional optical film affixing device is supposed to manufacture one optical product (optical film conjugate) from one panel. In such a conventional optical film affixing device, when aligning the optical film and the panel at the time of transfer, the entire position of one panel and one sheet are based on the alignment marks provided at the corners of the panel. It was configured to match the overall position of the optical film.

However, the conventional optical film affixing device is premised on manufacturing one optical product which is an optical film conjugate by one transfer process of the optical film to the panel, and to one optical film panel. It was not assumed that a plurality of optical products, which are optical film conjugates, would be produced by the transfer process of. Further, the conventional optical film affixing device has been desired to improve the positioning accuracy of the optical film on the panel.

In recent years, for example, as devices using relatively small display devices such as smartphones and tablet terminals have become widespread, optical film pasting devices are used to simultaneously manufacture a plurality of relatively small optical film conjugates as optical products. (That is, the production of a plurality of optical film conjugates from one panel) has become desired.

For example, the optical film is cut into a plurality of pieces by using the half-cut mechanism described in Patent Document 2, each optical film cut by the transfer body is transferred (attached) to the panel, and the panel is divided into a plurality of pieces. A plurality of optical film conjugates (optical products) can be manufactured.

However, the panel is configured to have an image forming layer, a transparent electrode, and the like inside. Therefore, it is necessary to predefine the division portion of the panel for each product, and accordingly, it is necessary to predefine the pasting area on which each optical film is transferred (pasted). Then, when an attempt is made to transfer (paste) each of the cut optical films to each sticking area of the panel, the relationship between the optical film and the sticking area is a plurality of to multiple relationships, so that the position of each optical film is And the position of each sticking area is likely to deviate from each other, and in particular, if the optical film has fine distortion, it cannot be properly transferred (pasted).

The present invention has been made to solve the above-mentioned problems, and by performing a transfer process of transferring (attaching) an optical film to a panel once in units of a plurality of sheets, a plurality of optical products can be obtained. of optical films conjugate simultaneously can be produced, also, the primary purpose of providing an optical science film sticking system Ru improve the alignment accuracy of the panel of the optical film.

However, the optical film affixing device 1 can also be used when manufacturing an optical film conjugate that is a material other than a liquid crystal display.

In the first embodiment, a mode in which the two optical film sticking devices 1 are used will be described. Of the two optical film sticking devices 1, one is a device for sticking the optical film 122 to the first surface (front surface) of the panel 110, and the other is a device for sticking the optical film 122 to the second surface (back surface) of the panel 110. It is a sticking device. Here, one device (a device for attaching the optical film 122 to the first surface (surface) of the panel 110) will be mainly described.

As shown in FIG. 1, the optical film attaching device 1 according to the first embodiment includes a control device 2, a stage 7, a booth 9, a deployment mechanism 10, a half-cut mechanism 20, a removal mechanism 30, a transfer mechanism 40, and a state. It has a monitoring unit 50.

The stage 7 is arranged in the extension direction of the roll film 120 in the development direction. The stage 7 is provided with an electrostatic adsorption mechanism (not shown), and attracts the panel 110 by the adsorption force generated by the electrostatic adsorption mechanism to hold the panel 110.

Outside the optical film affixing device 1, a supply unit 180, a panel transfer mechanism 181, another optical film affixing device 1Z, and a dividing mechanism 190 are provided.

The panel transport mechanism 181 transports the panel 110 from the supply unit 180 to the optical film pasting device 1 (see arrow A110a) when the optical film 122 is transferred (pasted) to the first surface (surface) of the panel 110. It is placed on the stage 7 of the optical film affixing device 1. Further, the panel transport mechanism 181 takes out the panel 110 from the stage 7 of the optical film affixing device 1 (see arrow A110b) when the optical film 122 is transferred (attached) to the second surface (surface) of the panel 110.

Further, the panel transport mechanism 181 takes out the panel 110 from the stage 7 of the optical film affixing device 1Z and transports the panel 110 to the split mechanism 190 at the time of dividing the panel 110.

(Structure of deployment mechanism)
The unfolding mechanism 10 includes a roll mounting portion 11, a carrier film winding portion 12, support bases 13 and 14, and guide rollers 15a, 15b, 15c, 16a and 16b.

The roll mounting portion 11 is a component to which the roll film 120 is mounted.
The carrier film winding unit 12 is a component that winds the carrier film 121 that constitutes the lower layer portion of the roll film 120.
The support bases 13 and 14 are bases that support the roll film 120 so as to be travelable from below.
The guide rollers 15a, 15b, 15c, 16a, 16b are rollers that guide the traveling of the roll film 120.

In the unfolding mechanism 10, the roll mounting portion 11 is arranged on the upstream side and the carrier film winding portion 12 is arranged on the downstream side in the traveling direction of the roll film 120, and the roll mounting portion 11 and the carrier film winding portion 12 are arranged. The support bases 13 and 14 and the guide rollers 15a, 15b, 15c, 16a and 16b are arranged between them.

The roll mounting portion 11, the carrier film winding portion 12, and the guide rollers 15a, 15b, 15c, 16a, 16b have rotation axes arranged in the same direction, and are configured to be rotatable in the same direction. There is.

The guide rollers 15a, 15b, and 15c are arranged at locations where the roll film 120 is curved (that is, where the traveling direction of the roll film 120 is changed). On the other hand, the guide rollers 16a and 16b are arranged at a place where the roll film 120 is not curved (that is, a place where the traveling direction of the roll film 120 is not changed). Hereinafter, when the guide rollers 15a, 15b, and 15c are collectively referred to, they are referred to as "guide rollers 15". Further, when the guide rollers 16a and 16b are collectively referred to, they are referred to as "guide rollers 16".

In the first embodiment, the guide roller 15a is arranged above the roll mounting portion 11. The guide roller 15b is arranged at a position on the downstream side in a substantially horizontal direction with respect to the guide roller 15a. The stage 7 is arranged at a position on the downstream side in a substantially horizontal direction with respect to the guide roller 15b. The guide roller 15c is arranged below the guide roller 15b. The carrier film winding portion 12 is arranged at a position in the direction of returning from the guide roller 15c to the roll mounting portion 11.

The roll film 120 is attached to the roll attachment portion 11. The roll film 120 is pulled out from the roll mounting portion 11, hung on the guide roller 15a, and then separated into an upper layer portion and a lower layer portion. The upper layer portion of the roll film 120 is composed of an optical film 122 including an adhesive layer, while the lower layer portion of the roll film 120 is composed of a carrier film 121 (see FIG. 3B).

The upper layer portion of the roll film 120 is attached to the unnecessary portion winding portion 32 of the removing mechanism 30. On the other hand, the lower layer portion of the roll film 120 is attached to the carrier film winding portion 12 after being hung on the guide rollers 15b and 15c.

The roll mounting portion 11 and the carrier film winding portion 12 are connected to a drive source (not shown) via a transmission mechanism (not shown). The transmission mechanism transmits the driving force of the drive source to the roll mounting portion 11 and the carrier film winding portion 12, and rotationally drives the roll mounting portion 11 and the carrier film winding portion 12.

At this time, the roll mounting portion 11 applies torque to the roll film 120 in the pulling direction. On the other hand, the carrier film winding unit 12 applies torque to the roll film 120 via the carrier film 121 in the winding direction (drawing direction from the roll mounting portion 11). That is, the roll mounting portion 11 and the roll film 120 apply torque to the roll film 120 in opposite directions. As a result, the roll film 120 is supported and developed by the roll mounting portion 11, the guide rollers 15a, 15b, 15c, and the carrier film winding portion 12.

At this time, as shown in FIG. 2, the roll film 120 unfolds straight from the guide roller 15a toward the stage 7 between the guide roller 15a and the guide roller 15b without causing fine distortion. It will be in the state of being.

Returning to FIG. 1, the guide rollers 16a and 16b are arranged between the guide rollers 15a and the guide rollers 15b. The guide roller 16b is arranged on the downstream side (the side closer to the stage 7) of the guide roller 16a. The guide rollers 16a and 16b are in contact with the lower surface of the roll film 120 developed between the guide rollers 15a and the guide rollers 15b.

The support base 13 is arranged between the guide roller 15a and the guide roller 16a. On the other hand, the support base 14 is arranged between the guide roller 16b and the guide roller 15b. The upper surfaces of the support bases 13 and 14 are formed in a flat surface shape, and are in contact with the lower surface of the roll film 120 developed between the guide rollers 15a and the guide rollers 15b.

The unfolding mechanism 10 conveys the roll film 120 to the downstream side by rotating the carrier film winding unit 12. When the uncut portion of the roll film 120 reaches the support base 13, the unfolding mechanism 10 stops the rotation of the carrier film winding portion 12 to stop the roll film 120. As a result, the uncut portion of the roll film 120 is arranged on the support base 13.

When the upper layer portion of the roll film 120 is cut by the half-cut mechanism 20, the unfolding mechanism 10 restarts the rotation of the carrier film winding unit 12 to run the roll film 120. As a result, the cut portion of the roll film 120 moves from the top of the support base 13 onto the support base 14. At this time, the uncut portion of the roll film 120 for the next transfer is arranged on the support base 13. The unfolding mechanism 10 repeats such an operation until the roll film 120 is in the end state (that is, the roll film 120 cannot be pulled out any more).

(Structure of half-cut mechanism)
The half-cut mechanism 20 includes a cutting means for cutting only the upper layer portion (optical film 122 and cover film 123) of the roll film 120 without cutting the lower layer portion (carrier film 121) of the roll film 120. The half-cut mechanism 20 preferably has a configuration capable of cutting the upper layer portion of the roll film 120 into an arbitrary shape including a non-rectangular shape such as an ellipse as well as a rectangular shape.

In the first embodiment, the case where the half-cut mechanism 20 includes the rotary pinnacle blade 21a as the cutting means will be described. However, the half-cut mechanism 20 may be configured to include another cutting means instead of the rotary pinnacle blade 21a.

The half-cut mechanism 20 brings the rotary pinnacle blade 21a into contact with the upper layer portion of the roll film 120 on the support base 13, and in that state, slides the rotary pinnacle blade 21a in the rolling direction. As a result, the half-cut mechanism 20 cuts only the upper layer portion of the roll film 120 and divides the upper layer portion of the roll film 120 into a transfer portion 124 and an unnecessary portion 125 of the optical film 122 (see FIG. 2). The transfer portion 124 and the unnecessary portion 125 of the optical film 122 include a cover film 123 formed on the optical film 122.

(Structure of removal mechanism)
The removing mechanism 30 includes a guide roller 17 and an unnecessary partial winding portion 32.
The guide roller 17 is a roller that guides the unnecessary portion 125 of the optical film 122 in the direction of the unnecessary portion winding portion 32.
The unnecessary portion winding portion 32 is a component that winds the unnecessary portion 125 of the optical film 122.

The guide roller 17 is arranged above the guide roller 16a so as to sandwich the roll film 120 with the guide roller 16a. The unnecessary portion winding portion 32 is arranged above the guide roller 17.

When the roll film 120 is attached to the roll attachment portion 11, the roll film 120 is separated into an upper layer portion (optical film 122 and cover film 123) and a lower layer portion (carrier film 121) at a position downstream of the guide roller 17. The upper layer portion of the roll film 120 is attached to the unnecessary portion winding portion 32. The lower layer portion of the roll film 120 is attached to the carrier film winding portion 12.

The unnecessary portion winding unit 32 is connected to a drive source (not shown) via a transmission mechanism (not shown). The transmission mechanism transmits the driving force of the drive source to the unnecessary partial winding unit 32 to rotationally drive the unnecessary partial winding unit 32.

At this time, the unnecessary partial winding portion 32 winds the upper layer portion (optical film 122 and cover film 123) of the roll film 120. The unnecessary portion winding portion 32 winds the unnecessary portion 125 of the optical film 122 by cutting the upper layer portion of the roll film 120 by the half-cut mechanism 20. As a result, the transfer portion 124 of the optical film 122 remains on the carrier film 121.

Such a guide roller 17 and an unnecessary portion winding portion 32 function as a peeling winding mechanism 31 for peeling the unnecessary portion 125 of the optical film 122 from the carrier film 121. However, the removing mechanism 30 may be configured to include another mechanism instead of the peeling winding mechanism 31. For example, the removing mechanism 30 may be configured to include a laser irradiation mechanism instead of the peeling winding mechanism 31. In this case, the laser irradiation mechanism irradiates the upper layer portion of the roll film 120 with a laser to vaporize only the unnecessary portion 125 of the optical film 122. As a result, the removing mechanism 30 removes the unnecessary portion 125 of the optical film 122 from the roll film 120.

(Structure of transfer mechanism)
The transfer mechanism 40 includes a transfer drum 41, a holding unit 42, an elevating cylinder 43, a vertical movement guide 44, a slide moving unit 45, and a vertical reference recognition camera 46.

The transfer drum 41 is a transfer body that transfers (attaches) the transfer portion 124 of the optical film 122 to the panel 110.
The holding portion 42 is a component that rotatably holds the transfer drum 41.
The elevating cylinder 43 is a component that elevates and elevates the transfer drum 41. The elevating cylinder 43 may be used in combination with the ball screw and the drive system of the servomotor to enable precise position control by the servomotor while ensuring the pressing pressure by the cylinder.
The vertical movement guide 44 is a component that moves the transfer drum 41 up and down.
The slide moving unit 45 is a component that slides and moves the transfer drum 41.
The vertical reference recognition camera 46 is a camera for detecting the position of the transfer portion 124 of the optical film 122 transferred to the transfer drum 41 and the position of the panel 110.

The transfer drum 41 is formed in a cylindrical shape. The surface of the transfer drum 41 is configured as a transfer surface 41a on which the transfer portion 124 of the optical film 122 is transferred. The transfer drum 41 first transfers the transfer portion 124 of the optical film 122 cut by the half-cut mechanism 30 to its own surface (transfer surface 41a), and then mounts the transfer portion 124 of the optical film 122 on the stage 7. Secondary transfer (attachment) is performed on the placed panel 110.

At the time of transfer, the transfer mechanism 40 finely adjusts the position of the stage 7 based on the position information of the transfer portion 124 of the optical film 122 on the transfer drum 41 detected by the vertical reference recognition camera 41, and the optical film with respect to the panel 110. The transfer portion 124 of 122 is attached to a predetermined position by the transfer drum 41. The identification of the arrangement direction of the panel 110 is performed, for example, by identifying an alignment mark (not shown) provided at a corner portion of the panel 110.

Further, the transfer mechanism 40 moves the transfer drum 41 along, for example, the arrow shown in FIG. 1 by operating the vertical movement guide 44 and the slide moving portion 45 at the time of transfer. At that time, the transfer mechanism 40 rotates the transfer drum 41 at a desired timing. As a result, the transfer mechanism 40 primary transfers the transfer portion 124 of the optical film 122 to the transfer surface 41a of the transfer drum 41, or transfers the transfer portion 124 of the optical film 122 to the panel 110 mounted on the stage 7. Secondary transfer (paste) is performed.

(Configuration of condition monitoring unit)
The condition monitoring unit 50 includes an imaging unit 51, a transfer mechanism control unit 53, and a comparison unit 54.

The imaging unit 51 is a component that images the surface (transfer surface 41a) of the transfer body (transfer drum 41).
The transfer mechanism control unit 53 is a component that controls the operation of the transfer mechanism 40.
The comparison unit 54 was cut by the half-cut mechanism 20 and the shape of the transfer portion 124 of the optical film 122 that was primarily transferred to the transfer surface 41a of the transfer drum 41, which is reflected in the image captured by the image pickup unit 51. It is a component for comparison with the cutting pattern of the transfer portion 124 of the optical film 122.

The imaging unit 51 is arranged along the lateral direction of the roll film 120 so as to face at least the entire region on the surface of the transfer drum 41 where the optical film 122 is primarily transferred. That is, the imaging unit 51 is configured to image substantially the entire surface of the transfer surface 41a of the transfer drum 41 along the rotation axis direction of the transfer drum 41. The image pickup unit 51 includes, for example, a large number of image pickup elements, and each image pickup element is arranged along the rotation axis direction of the transfer drum 41. Each image pickup device is arranged so that at least the transfer portion 124 of the optical film 122 of the transfer surface 41a of the transfer drum 41 faces the entire region to which the primary transfer is performed. If the image pickup device cannot correspond to all the regions to be transferred, the image pickup unit 51 can be moved to image the transfer portion 124 of the optical film 122 in the entire region of the transfer drum 41.

The comparison unit 54 has the shape of the transfer portion 124 of the optical film 122 primaryly transferred to the transfer surface 41a of the transfer drum 41 and the optical film cut by the half-cut mechanism 20 in the image captured by the image pickup unit 51. Compare with the cutting pattern of the transfer portion 124 of 122. As a result, the comparison unit 54 detects the presence or absence of transfer defects in the optical film 122. Here, the "impairment of transfer of the optical film 122" means, for example, the occurrence of transfer defects or omissions of the transfer portion 124 of the optical film 122 that has been primarily transferred to the transfer surface 41a of the transfer drum 41.

When the transfer mechanism control unit 53 detects a transfer defect of the optical film 122 by the comparison unit 54, the transfer mechanism control unit 53 calls attention to the operator by displaying a bad mark or the like on a display unit (not shown), for example. Can be done. Further, in this case, the transfer mechanism control unit 53 may control the panel transfer mechanism 181 so as to exclude the panel 110 to which the transfer portion 124 of the optical film 122 is secondarily transferred (attached) from the production line. ..

<Composition of roll film>
Hereinafter, the configuration of the roll film 120 will be described with reference to FIG. FIG. 3 is a diagram showing the configuration of the roll film 120. FIG. 3A shows the configuration of the roll film 120 attached to the roll attachment portion 11, and FIG. 3B shows the unnecessary portion 125 of the optical film 122 (see FIGS. 1 and 2). ) Is removed, and the structure of the roll film 120 is shown.

As shown in FIG. 3A, the roll film 120 has a configuration in which an optical film 122 including an adhesive layer is arranged on a carrier film 121, and a cover film 123 is arranged on the optical film 122.

The adhesive force between the adhesive layer of the optical film 122 and the carrier film 121 is weaker than the adhesive force between the adhesive layer and the optical film 122. Therefore, the optical film 122 including the adhesive layer can be easily peeled off from the carrier film 121.

The upper layer portion (optical film 122 and cover film 123) of the roll film 120 is cut into an arbitrary shape by the half-cut mechanism 20. As a result, the upper layer portions (optical film 122 and cover film 123) of the roll film 120 are the transfer portion 124 of the optical film 122 (see FIGS. 1 and 2) and the unnecessary portion 125 of the optical film 122 (FIGS. 1 and 2). (See) and is divided into.

The unnecessary portion 125 (see FIG. 1) of the optical film 122 is removed from above the carrier film 121 by the removing mechanism 30. As a result, as shown in FIG. 3B, the transfer portion 124 of the optical film 122 remains on the carrier film 121.

The transfer portion 124 of the optical film 122 is transferred (attached) to the panel 110 by the transfer mechanism 40 (see FIG. 4). FIG. 4 is a diagram showing the operation of the optical film affixing device 1 at the time of transfer.

For example, at the time of transfer, the transfer mechanism 40 moves the transfer drum 41 along the arrow shown in FIG. Specifically, first, the transfer mechanism 40 lowers the transfer drum 41 on the support base 14. As a result, as shown in FIG. 4A, the transfer mechanism 40 brings the transfer surface 41a of the transfer drum 41 into contact with the transfer portion 124 of the optical film 122.

Next, as shown in FIG. 4B, the transfer mechanism 40 moves the transfer drum 41 to the downstream side (the side closer to the stage 7) while rotating the transfer drum 41. At this time, the transfer portion 124 of the optical film 122 is primarily transferred to the transfer surface 41a of the transfer drum 41.

Next, the transfer mechanism 40 raises the transfer drum 41. At this time, the optical film attaching device 1 monitors the vertical movement of the transfer drum 41 based on the captured image captured by the vertical reference recognition camera 46. At this time, the optical film sticking device 1 is a transfer portion 124 of the optical film 122 that is primarily transferred to the transfer surface 41a of the transfer drum 41 based on the image captured by the image pickup unit 51 of the state monitoring unit 50. Monitor transcription defects.

The purpose of monitoring the vertical movement of the transfer drum 41 is to move the lower end portion of the transfer drum 41 to the panel 110 so that the transfer drum 41 does not collide with the panel 110 when the transfer drum 41 is moved onto the stage 7. This is to raise the drum to a position sufficiently higher than the upper surface of the drum.

Next, the transfer mechanism 40 moves the transfer drum 41 onto the stage 7, and then lowers the transfer drum 41. As a result, as shown in FIG. 4C, the transfer mechanism 40 brings the transfer portion 124 of the optical film 122, which is primarily transferred to the transfer surface 41a of the transfer drum 41, into contact with the upper surface of the panel 110.

Next, as shown in FIG. 4D, the transfer mechanism 40 moves the transfer drum 41 to the downstream side (the side closer to the stage 7) while rotating the transfer drum 41. At this time, the transfer portion 124 of the optical film 122 is secondarily transferred (attached) to the upper surface of the panel 110. In the first embodiment, the transfer portion 124 of the optical film 122 functions as a polarizing plate by being transferred (attached) to the panel 110.

Finally, the transfer mechanism 40 raises the transfer drum 41 to move the transfer drum 41 onto the support base 14.

<Operation of optical film affixing device>
Hereinafter, the operation of the optical film attaching device 1 will be described with reference to FIGS. 1, 5, and 6A to 6H. FIG. 5 is a flowchart showing the operation of the optical film attaching device 1. 6A to 6H are diagrams showing an operation example of the optical film attaching device 1. 6A to 6H show the top view configuration and the side view configuration of the roll film 120 or the panel 110 side by side, respectively.

The optical film sticking device 1 operates based on the time measured by a timer (not shown). Further, the operation of the optical film sticking device 1 is defined by a program readable and stored in advance in a storage unit (not shown) of the control device 2, and is executed by a CPU (not shown) of the control device 2. Hereinafter, since these points are conventional means in information processing, detailed description thereof will be omitted.

As shown in FIG. 5, the optical film attaching device 1 performs a process for the first surface (surface) of the panel 110 (step S10). In step S10, the following processes S15 to S30 are performed on the first surface (surface) of the panel 110.

First, the unfolding mechanism 10 unfolds the roll film 120 so that it can travel while applying torque (step S15). FIG. 6A shows the state of the optical film 122 at this time. As shown in FIG. 6A, the roll film 120 is in a straight unfolded state without causing fine distortion.

Next, the half-cut mechanism 20 cuts the upper layer portion of the roll film 120 into the transfer portion 124 and the unnecessary portion 125 of the optical film 122 on the support base 13 (step S20). FIG. 6B shows the state of the optical film 122 at this time.

Next, the removing mechanism 30 removes the unnecessary portion 125 of the optical film 122 from the roll film 120 (step S25). As a result, the transfer portion 124 of the optical film 122 remains on the carrier film 121. FIG. 6C shows the state of the optical film 122 at this time.

Next, the transfer mechanism 40 primary transfers the transfer portion 124 of the optical film 122 remaining on the carrier film 121 onto the transfer surface 41a of the transfer drum 41 on the support base 14, and the transfer drum 41 is transferred to the stage 7. The transfer portion 124 of the optical film 122 is secondarily transferred (attached) to the panel 110 on the stage 7 (step S30). FIG. 6D shows the state of the transfer portion 124 of the optical film 122 at this time. As shown in FIG. 6D, the panel 110 is in a state in which the transfer portion 124 of the optical film 122 is transferred to the first surface (surface).

As shown in FIG. 6D, in the first embodiment, the panel 110 is a liquid crystal layer (image forming layer) (image forming layer) arranged between the two substrates 110a and 110b and the two substrates 110a and 110b. ) And is configured as a plate-shaped multilayer panel. The substrate 110a is a color filter substrate that constitutes the first surface (front surface) side of the liquid crystal display. The substrate 110b is an array substrate that constitutes the second surface (back surface) side of the liquid crystal display.

The first surface (front surface) and the second surface (back surface) of the panel 110 are each formed in a flat surface shape. A display region 113 (see FIG. 14A) provided with pixels such as RGB for displaying an image is formed on the liquid crystal layer inside the panel 110. Further, on the surface of the panel 110, a sticking region 114 (see FIG. 14A) to which the transfer portion 124 of the optical film 122 is transferred and pasted is formed.

The sticking area 114 (see FIG. 14A) is formed to be slightly wider than the display area 113 so as to cover the entire display area 113 (see FIG. 14A). The transfer portion 124 of the optical film 122 is formed slightly wider than the sticking area 114 so as to cover the entire area of the sticking area 114 (see FIG. 14A), and is stuck on the sticking area 114.

After step S30, the panel 110 is transported from the optical film pasting device 1 to the optical film pasting device 1Z by the panel transport mechanism 181. Then, the optical film attaching device 1Z performs the treatment for the second surface (surface) of the panel 110 (step S10a). In step S10a, the processes of steps S15a to S30a are performed on the second surface (back surface) of the panel 110. The processes of steps S15a to S30a are the same as the processes of steps S15 to S30 of step S10.

As shown in FIG. 6E, the panel 110 is in a state where the first surface (front surface) and the second surface (back surface) are inverted (that is, the substrate 110b which is an array substrate) in the process of performing the process of step S10a. Is arranged on the upper side, and the substrate 110a, which is a color filter substrate, is arranged on the lower side), and is placed on the stage 7 of the optical film affixing device 1Z.

Then, as shown in FIG. 6F, the panel 110 is in a state where the transfer portion 124 of the optical film 122 is transferred to the first surface (front surface) and the second surface (back surface) by the processing of step S30a. become.

In the process of step S10a, the first surface (front surface) and the second surface (back surface) of the panel 110 taken out from the optical film affixing device 1 are inverted, and the panel 110 is attached to the optical film affixing device 1 in that state. By returning it, it is possible to make the optical film affixing device 1 perform the operation.

After step S30a, the panel 110 is conveyed from the optical film affixing device 1Z to the dividing mechanism 190 by the panel conveying mechanism 181. At this time, as shown in FIG. 6G, the panel 110 is in a state where the first surface (front surface) and the second surface (back surface) are inverted again and returned to their original state (that is, the substrate 110a which is a color filter substrate). Is arranged on the upper side, and the substrate 110b, which is an array substrate, is arranged on the lower side), and is conveyed to the dividing mechanism 190.

Then, the dividing mechanism 190 divides the panel 110 into a plurality of optical film conjugates according to each pasting area 114 (see FIG. 14A) described later (step S35).

At this time, the division mechanism 190 performs a scribe process (process in step S36) and a panel division process (process in step S37). The scribe process (process in step S36) is a process for forming a groove 112 (see FIG. 6G) at a portion of the panel 110 to be divided. On the other hand, the panel division process (process in step S37) is a process for dividing the panel 110 along the groove 112 (see FIG. 6G).

FIG. 6G shows the state of the panel 110 at the time of scribe processing (processing in step S36). Further, FIG. 6H shows the state of the panel 110 at the time of the panel division process (process of step S37). As shown in FIG. 6G, a groove 112 is formed in the panel 110 during the scribe process (process in step S36). Then, as shown in FIG. 6H, at the time of the panel division process (process of step S37), the panel 110 is cut along the groove 112, and the unnecessary portion is further removed. As a result, the panel 110 is in a state of being divided into a plurality of optical film conjugates 131. As a result, a plurality of optical film conjugates 131 as optical products are manufactured. In the example shown in FIG. 6H, the optical film coupler 131 has a rectangular shape, but it can be formed into any shape other than the rectangular shape.

When the dividing mechanism 190 is provided inside the optical film pasting device 1 (or the optical film pasting device 1Z), the process of step S35 is performed by the optical film pasting device 1 (or the optical film pasting device 1Z). be able to.

<Main features of optical film affixing device>
The optical film attaching device 1 according to the first embodiment has the following features.
(1) The unfolding mechanism 10 is arranged so as to extend in the unfolding direction of the roll film 120. The unfolding mechanism 10 unfolds the roll film 120 so that it can travel while applying torque. The half-cut mechanism 20 and the transfer body (transfer drum 41) are arranged above the development mechanism 10 along the development direction of the roll film 120.

In such an optical film attaching device 1, the roll film 120 having the optical film 122 bonded to the surface is developed in a state where torque is applied along the drawing direction, and the upper layer portion of the roll film 120 is cut in that state. Then, it is transferred to the panel 110.

At this time, the optical film sticking device 1 cuts the optical film 122 into a plurality of transfer portions 124 in accordance with the plurality of sticking regions 114 (see FIG. 14A) formed on the panel 110, and transfers the optical film 122 to the panel 110. Can be done.

In such an optical film affixing device 1, the transfer process of transferring (adhering) the optical film 122 to the panel 110 is performed once for each product of a plurality of sheets (that is, the transfer process is performed for a plurality of sheets per sheet). By performing this once for one multi-imposition panel including the circuit board for the optical film conjugate), a plurality of optical film conjugates can be manufactured at the same time as an optical product.

Moreover, since the optical film sticking device 1 develops the roll film 120 in a state where torque is applied along the drawing direction, it is possible to suppress the occurrence of fine distortion in the optical film 122.

As a result, the optical film affixing device 1 attaches the optical film 122 (particularly, each transfer portion 124 when the optical film 122 is cut into a plurality of transfer portions 124) to the corresponding affixing region 114 (see FIG. 14A) of the panel 110. It can be accurately transferred to the position. Therefore, the optical film affixing device 1 can improve the positioning accuracy of the transfer portion 124 of the optical film 122 with respect to the panel 110. As a result, the optical film affixing device 1 can improve the quality of the optical product to be manufactured.

(2) The stage 7 is arranged in the extension direction of the roll film 120 in the development direction. The transfer drum 41 first transfers the transfer portion 124 of the optical film 122 to its own surface on the unfolding mechanism 10, and then moves above the stage 7 along the unfolding direction of the roll film 120 to move the stage 7 to the stage 7. The transfer portion 124 of the optical film 122 is secondarily transferred (attached) to the panel 110.

In such an optical film attaching device 1, the transfer portion 124 of the optical film 122 is transferred to the panel 110 by moving the transfer drum 41 along the development direction of the roll film 120 (that is, the development direction of the optical film 122). do. At that time, the transfer portion 124 of the optical film 122 on the transfer drum 41 does not move in the direction of the central axis of the arc of the transfer drum 41.

Therefore, the optical film attaching device 1 can prevent the transfer portion 124 of the optical film 122 from being displaced in the central axis direction of the arc of the transfer drum 41. Therefore, the optical film attaching device 1 can efficiently improve the positioning accuracy of the transfer portion 124 of the optical film 122 with respect to the panel 110. As a result, the optical film affixing device 1 can further improve the quality of the optical product to be manufactured.

Further, the optical film affixing device 1 establishes a place where the primary transfer of the transfer portion 124 of the optical film 122 is performed and a place where the secondary transfer (paste) of the transfer portion 124 of the optical film 122 is performed along the development direction of the roll film 120. The support bases 13 and 14 that support the roll film 120 when performing the primary transfer can be arranged inside the unfolding mechanism 10.

Therefore, the optical film pasting device 1 performs processing such as position detection of the panel 110, primary transfer, position detection of the optical film primary transferred to the transfer drum 41, and secondary transfer (pasting) in a relatively narrow space. The configuration can be realized.

(3) The optical film pasting device 1 has a condition monitoring unit 50. The condition monitoring unit 50 includes an imaging unit 51 and a comparison unit 54. The comparison unit 54 determines the shape of the transfer portion 124 of the primary transferred optical film 122 and the cutting pattern of the transfer portion 124 of the optical film 122 cut by the half-cut mechanism 20 in the image captured by the imaging unit 51. compare. The comparison unit 54 is based on the comparison result when a transfer defect of the optical film 122 (for example, transfer failure or omission in the optical film 122 primaryly transferred to the surface of the transfer drum 41) has occurred. Can be detected.

In such an optical film pasting device 1, if the comparison unit 54 finds a transfer defect of the optical film 122, for example, the secondary transfer (paste) of the optical film 122 from the transfer drum 41 to the panel 110 is stopped. Alternatively, the panel 110 to which the optical film 122 is secondarily transferred (attached) from the transfer drum 41 can be excluded from the production line. As a result, the optical film affixing device 1 can distinguish between a usable device portion and an unusable device portion in the manufacture of a multi-faceted panel, and can improve the yield of the optical product.

(4) The panel 110 includes one or more sticking areas 114 (see FIG. 14A) on which the optical film 122 is transferred. The half-cut mechanism 20 cuts the optical film 122 so that each transfer portion 124 of the optical film 122 is wider than each attachment area 114 according to each attachment area 114. Then, the transfer drum 41 transfers each transfer portion 124 of the optical film 122 to the panel 110 so that each transfer portion 124 of the cut optical film 122 covers the entire area of each attachment region 114.

Such an optical film sticking device 1 sets a tolerance in the transfer portion 124 of the optical film 122 by cutting the transfer portion 124 of the optical film 122 wider than the sticking region 114 (see FIG. 14A), and the optical film thereof. The transfer portion 124 of 122 is transferred to the panel 110. As a result, the optical film affixing device 1 is allowed to roughly transfer the transfer portion 124 of the optical film 122 to the panel 110, so that the productivity (manufacturing capacity) of the optical product can be improved.

As described above, according to the optical film affixing apparatus 1 according to the first embodiment, the transfer process of transferring (adhering) the optical film 122 to the panel 110 is performed once for each of a plurality of sheets of the optical product. As a result, a plurality of optical film conjugates can be produced at the same time. Further, according to the optical film sticking device 1, the accuracy of positioning the transfer portion 124 of the optical film 122 with respect to the panel 110 can be improved.

[Embodiment 2]
The optical film attaching device 1 according to the first embodiment has a configuration in which a rotary pinnacle blade 21a is used as a cutting means of the half-cut mechanism 20.

On the other hand, in the second embodiment, the optical film attaching device 1A using the laser irradiation mechanism 22 is provided as the cutting means of the half-cut mechanism 20.

In the second embodiment, it is assumed that the optical film attaching device 1A simultaneously manufactures a plurality of small optical film conjugates having an elliptical shape as an optical product by using the laser irradiation mechanism 22. explain. Such an optical film conjugate can be used, for example, in a speedometer of an automobile, a motorcycle, or the like.

Hereinafter, the configuration of the optical film pasting device 1A according to the second embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a diagram showing a side surface configuration of the optical film pasting device 1A. FIG. 8 is a diagram showing a top surface configuration of the optical film pasting device 1A.

As shown in FIG. 7, the optical film affixing device 1A according to the second embodiment is a rotary pinnacle as a cutting means of the half-cut mechanism 20 as compared with the optical film affixing device 1 (see FIG. 1) according to the first embodiment. The difference is that the laser irradiation mechanism 22 is provided instead of the blade 21a.

The laser irradiation mechanism 22 is a mechanism for irradiating a laser. The laser irradiation mechanism 22 cuts the upper layer portion (optical film 122 and cover film 123) of the roll film 120 into an arbitrary shape by irradiating the roll film 120 with a laser. At this time, the laser irradiation mechanism 22 can cut the upper layer portion of the roll film 120 into a non-rectangular shape such as an ellipse as shown in FIG. 8, for example. The laser irradiation mechanism 22 can also cut the upper layer portion of the roll film 120 so that the transfer portions 124 having different sizes and shapes are mixed.

Hereinafter, a specific example of the operation of the optical film attaching device 1A will be described with reference to FIGS. 9A to 9H. 9A to 9H are diagrams showing an operation example of the optical film attaching device 1A. 9A to 9H show the top view configuration and the side view configuration of the roll film 120 or the panel 110 side by side, respectively.

As shown in FIG. 9A, at the time of processing in step S15 of FIG. 5, the optical film affixing device 1A unfolds the roll film 120 in a state of applying torque by the unfolding mechanism 10 so that the roll film 120 can travel. The 120 is brought into a straight unfolded state without causing fine distortion.

As shown in FIG. 9B, at the time of processing in step S20 of FIG. 5, the optical film attaching device 1A cuts the upper layer portion (optical film 122 and cover film 123) of the roll film 120 by the half-cut mechanism 20. The transfer portion 124 and the unnecessary portion 125 of the optical film 122 are formed.

As shown in FIG. 9C, during the process of step S25 of FIG. 5, the optical film affixing device 1A removes the unnecessary portion 125 of the optical film 122 from the roll film 120 by the removing mechanism 30, thereby removing the unnecessary portion 125 of the optical film 122. The transfer portion 124 is left on the carrier film 121.

As shown in FIG. 9D, during the process of step S30 of FIG. 5, the optical film attaching device 1A transfers the transfer portion 124 of the optical film 122 to the first surface (surface) of the panel 110 by the transfer mechanism 40.

After step S30 of FIG. 5, the panel transport mechanism 181 takes out the panel 110 from the optical film pasting device 1 and transports it to the optical film pasting device 1Z. In the process, as shown in FIG. 9E, the panel 110 is in a state where the first surface (front surface) and the second surface (back surface) are inverted by a mechanism (not shown) (that is, the substrate 110b which is an array substrate). Is arranged on the upper side, and the substrate 110a, which is a color filter substrate, is arranged on the lower side).

As shown in FIG. 9F, during the process of step S30a of FIG. 5, the optical film attaching device 1Z transfers the transfer portion 124 of the optical film 122 to the second surface (back surface) of the panel 110.
