Description

Film member pasting device and film member pasting method

The present invention relates to a film member pasting device and a film member pasting method for attaching a film member to a member to be adhered.

After peeling off the release film from the film member to which the release film is peelable, the film member attaching device for attaching the film member from which the release film was peeled to the to-be-attached member has been proposed in various ways (for example, Patent Document 1). Reference).

7 is a view showing the main parts of the film member pasting device 800 described in Patent Document 1 taken out. In addition, in patent document 1, it is called a "plastic film bonding apparatus", but in this specification, it is described as a "film member pasting apparatus."

In the film member pasting device 800 described in Patent Document 1, as shown in FIG. 7, the release film 810 is peeled from the film member 820 to which the release film 810 is detachably attached. A peeling unit 830 is provided. The peeling unit 830 is provided with a peeling portion 840, and a folding portion 841 is formed at the distal end of the peeling portion 840, and the folding portion 841 is an edge portion (wedge-shaped edge). Part). Then, the release film 810 is configured to move in the direction of the arrow x'by changing the traveling direction by the roll 850 after the direction is changed in the folding portion 841 of the peeling portion 840.

In such a peeling unit 830, when peeling the release film 810 from the film member 820, on the upper surface of the peeling unit 830, the film member 820 is adsorbed (not shown). In the adsorbed state, the peeling unit 830 is slid in the arrow x direction. Thereby, the release film 810 can be peeled from the film member 820.

On the other hand, the film member 820 adsorbed by the adsorption device is transferred to a predetermined affixing position of the affixed member (not shown) and affixed to the affixed position.

Japanese Patent Publication No. 2011-251805

In the film member pasting apparatus 800 described in patent document 1, the release film 810 is peeled from the film member 820 to which the release film 810 is attached so that peeling is possible, and the release film 810 is released. Although the peeled film member 820 can be affixed to the member to be adhered, a problem to be improved remains in the peeling part 840 for peeling the release film 810 from the film member 820.

That is, in the peeling portion 840 used in the film member pasting device 800 described in Patent Document 1, the folding portion 841 is an edge portion, and in the folding portion 841, the release film 810 is released. To change direction. In such a film member attaching device 800, the release film is tensioned (tension) along the longitudinal direction of the release film by a tension imparting portion such as a dancer roll, and tension is applied. It is common to peel the film member by advancing the release film. For this reason, depending on the material of the release film 810, there is a problem that the release film is damaged due to the friction by the folding portion 841 and the release film 810 is torn or broken. When the release film 810 is damaged, it also leads to the occurrence of obstacles in the operation of the film member and the release operation of the release film 40.

Moreover, the same problem arises in another film member pasting device having a peeling part similar to the peeling part 840 used in the film member pasting device 800 described in Patent Literature 1.

8 is a view for explaining an example of another conventional film member attaching device 900. Hereinafter, the film member pasting apparatus 800 (refer FIG. 7) described in patent document 1 is called "conventional first film member pasting apparatus 800," and another film member pasting apparatus 900 shown in FIG. ) Is referred to as "conventional second film member attaching device 900". In addition, FIG. 8 schematically shows the peeling part used for the conventional 2nd film member pasting apparatus 900. As shown in FIG.

As shown in FIG. 8, even in the conventional second film member attaching device 900, the peeling part peeling the release film 910 from the film member 920 to which the release film 910 is detachably attached 930 is provided. Also in the peeling portion 930, the folding portion 931 is an edge portion (wedge-shaped edge portion), and after the release film 910 is turned in the folding portion 931, the release film 910 ), the release film 910 is peeled from the film member 920 to which the release film 910 is detachably attached by advancing in the arrow x direction.

However, in the conventional second film member attaching device 900, when peeling the release film 910, the film member 920 is not adsorbed by the adsorption device, but the release film 910 is peeled. By slightly advancing the film member 920, the front end portion 920a (sometimes abbreviated as the tip portion 920a) of the film member 920 in the traveling direction is attached to the abutment starting end 940a of the affixed member 940. After reaching, the tip portion 920a of the film member 920 is pressed with a pressing roll 950 or the like, and the table 960 is moved along the guide rail 970 in the direction of the arrow x', and the folding portion At (931), the release film that has been redirected is pulled in the direction of the arrow x. Thereby, the film member 920 is affixed to the object to be adhered 940.

In the conventional second film member attaching device 900, as in the conventional first film member attaching device 800, the release film 910 is switched from the wedge-shaped folding part 931, Since tension is applied to the release film, depending on the material of the release film 910, the release film 910 is torn or broken due to friction by the folding portion 841, and the release film is damaged. There is a problem of becoming.

In order to solve such a problem, the folding portion 931 is not an edge portion, but the folding portion 931 is a folding portion 931a having a rounded portion, as shown in the broken line frame C in FIG. 8. Although it may be considered to be, in the conventional second film member affixing device 900, the relationship between the folding portion and the abutting end 940a of the affixed member 940 becomes important.

The reason is that in the conventional second film member attaching device 900, the tip portion 920a of the film member 920 from which the release film 910 is peeled off by the folding portion 931 reaches the member to be joined. This is because a high precision is required for the precision of the reaching position when making it.

That is, in the conventional second film member attaching device 900, the film member 920 from which the release film 910 is peeled from the folding part 931 of the peeling part 930 is an inclined surface of the peeling part 930. After extending the extension of 932, the tip 920a of the film member 920 reaches the tip 940a of the affixed member 940, and then the tip 920a of the film member 920 ) Is pressed by the pressing roll 950 or the like, the table 960 is moved along the guide rail 970 in the direction of the arrow x', and the release film 910 switched in the folding portion 931 This is because the operation of advancing in the direction of the arrow x is performed.

For this reason, if the accuracy of the reaching position when reaching the tip 920a of the film member 920 to reach the member 940 is low, the film member 920 sticks to the correct position of the member 940. It will not work. Specifically, for example, as shown in the broken line frame C in FIG. 8, when the folding portion 931 is a folding portion 931a having a rounded portion, the release film is released from the folding portion 931a. In the peeled film member 920, when the elongated surface of the inclined surface 932 of the peeling part 930 is advanced, the tip end portion 920a of the film member 920 is a sticking end end 940a of the member 940. In some cases, the distance until reaching the elongation increases, and there is a case where it bends due to its own weight until it reaches the abutment starting end 940a. For this reason, the tip 920a of the film member 920 does not reach the abutting end 940a of the affixed member 940 with high precision, so that the film member 920 is affixed to the affixed member 940 accurately. I have a problem that I can't. When the diameter of the rounded portion is increased, this tendency becomes more pronounced.

Such a problem, that is, the tip portion 920a of the film member 920 does not reach the abutting end 940a of the affixed member 940 with high precision, so that the film member 920 is affixed to the affixed member 940 The problem of not being able to be accurately attached to the same is not only the case where the folding portion 931 is a folding portion 931a having a rounded portion, but also when the folding portion 931 is rolled (not shown), for example. Occurs.

That is, even when the folding portion 931 is rolled, as in the case of the folding portion 931a having a rounded portion, the film member 920 from which the release film 910 is peeled off is an inclined surface of the peeling portion 930 When extending the extension of 932, the distance from reaching the abutting end 940a of the abutting member 940 becomes longer, so that the tip 920a of the film member 920 is the abutting member ( A problem arises in that the affixing end 940a of 940) is not reached with high precision. For this reason, it is preferable that the folding portion is an edge portion (especially a wedge-shaped edge portion), but when the folding portion is a wedge-shaped edge portion, a problem arises that the release film is liable to be damaged as described above.

In addition, the problem that the release film is liable to be broken is not only caused by the folding portion of the peeling portion being an edge portion such as a wedge shape, but even if the folding portion has a somewhat rounded portion, there is a possibility that it may be caused by long-term use or the like. For this reason, such a problem exists in common in the film member pasting apparatus which affixes a film member to a to-be-attached member while peeling a release film by turning a release film in the folding part of a release part.

The present invention has been made in view of the above circumstances, and the tension (tension) applied to the release film is small when the film member is attached to the member to be adhered while the release film is peeled by changing the release film from the folding portion to the folding part. It aims at providing the film member pasting apparatus and the film member pasting method which can suppress the breakage of a release film by doing so.

[1] In the film member attaching apparatus of the present invention, one side is an adhesive surface, and the film member is advanced while peeling the release film from the film member on which the release film is detachably attached to the adhesive surface. , After performing the "first alignment operation of the film member" for reaching the starting end of the film member from which the release film has been peeled, to reach the starting end of the film member, the leading end of the film member in the traveling direction It is a film member pasting device which performs the "film member pasting operation" which affixes the film member to the member to be affixed while peeling off the release film starting from the starting end of the affix while being pressed against the affixing end of the member, A film member initial alignment control function for controlling the film member supply mechanism to perform the "first alignment operation of the film member", a table for loading the member to be joined, a film member supply mechanism for supplying the film member, and the , A control device having a sticking control function for relatively moving at least one of the film member supply mechanism part and the table in order to perform the "sticking operation of the film member", wherein the film member supply mechanism part includes the release film By having a folding portion for switching the direction of the film member in a direction substantially opposite to the direction of travel, the film member supply mechanism portion and at least one of the table is relatively moved in the state in which the release film is reversed in the folding portion. It has a peeling portion for peeling the release film from the film member, and a release film advancing mechanism portion for advancing the release film switched in direction from the folding portion. When the tension film is provided between the tension imparting portion for imparting tension along the direction in which the release film advances, and the tension imparting portion and the peeling portion, and when performing the "sticking operation of the film member", the tension film is applied to the tension part. Whether or not and between the peeling parts Clamping/peeling synchronous mechanism part which clamps at a predetermined position of and performs an operation of peeling the release film from the film member by actively synchronizing with the "sticking operation of the film member" between the clamped position and the peeling part It is characterized by being provided.

In this way, in the present invention, when performing the "sticking operation of the film member" to the release film advancing mechanism part, the release film is clamped at a predetermined position between the tensioning part and the peeling part, and the clamped position and the peeling part In the meantime, a sticking/peeling synchronous mechanism part is provided that actively synchronizes with the "sticking action of the film member" and performs the action of peeling the release film from the film member. For this reason, when performing the sticking operation of a film member, it is possible to make the action of peeling the release film from the film member in synchronization with the "sticking action of the film member".

Specifically, when performing the "film member attaching operation", the release film is in a clamped state, so the release film is released from tension by the tension applying unit, and the tension applied to the release film is It is only the tension between the clamper and the peeling portion. And in this state, since the operation|movement which peels a release film from a film member is performed in synchronization with the sticking operation of a film member, the tension applied to a release film becomes small. For this reason, even with a configuration in which a large tension is applied to the release film by the tension applying unit, the release film is released from the tension by the tension applying unit, and a very large tension is not applied to the release film.

Thereby, according to the film member pasting apparatus of this invention, when performing the pasting operation of a film member, the tension applied to a release film can be made small. Thereby, it is possible to suppress that the release film is broken by rubbing the release film at the folding portion of the peeling portion. In addition, when the film member pasting device is used for a long time, there is also a problem that the folding part is worn out due to friction with the release film, but according to the film member pasting device of the present invention, it is also possible to suppress wear of the folding part.

In addition, "actively synchronizing" means "actively" has the same meaning as "actively", for example. Therefore, to say "actively synchronized to peel the release film from the film member", for example, "actively synchronized to peel the release film from the film member" It might be.

[2] In the film member pasting apparatus of the present invention, the affixing/peeling synchronization mechanism part is provided at a predetermined position between the tensioning part and the peeling part, and the release film is between the tensioning part and the peeling part. A clamper clamped at a predetermined position of, located between the clamper and the peeling portion, and is provided on the side of the film member supply mechanism, the release film peeled off from the peeling portion is substantially the same as the traveling direction of the film member The first folding roll that changes direction to advance in the direction, and is located between the clamper and the first folding roll, and is also installed on the table side, the release film switched from the first folding roll to the It is desirable to have a second folding roll that is diverted to advance in a direction substantially opposite to the direction of travel of the film member.

When the affixing/peeling synchronous mechanism portion has such a structure, when performing the affixing operation of the film member, the film member is actively synchronized with the "sticking operation of the film member" between the clamped position and the peeling portion. The action of peeling the release film can be performed.

[3] In the film member pasting apparatus of the present invention, the table is provided with a lifting mechanism for moving the table up and down in the vertical direction, and when the "film member affixing operation" is performed, the table is in the vertical direction. When the position is the reference position in the vertical direction, the control device moves the lifting mechanism to temporarily lower the table in the downward direction from the vertical reference position when performing the "first alignment operation of the film member". By controlling, the "first fitting operation of the film member" is performed by the first alignment control function of the film member, and the table is raised to the vertical reference position at a predetermined timing until the sticking operation of the film member is started. It is preferable to further have a table lift control function for controlling the lift mechanism so as to make it.

As described above, when performing the initial alignment operation of the film member, the initial alignment operation of the film member is performed while the table is temporarily lowered (retracted) in the downward direction from the vertical reference position, and the attaching operation of the film member is started. The lifting mechanism is controlled to raise (return) the table to the reference position in the up-down direction at a predetermined timing until it becomes possible. By performing such control, the film member can be first-fitted with high precision, whereby the tip end of the film member in the traveling direction can reach the starting end of the affixed member with high precision.

That is, since the adhesive is applied to the film member from which the release film has been peeled off, if the initial alignment operation of the film member is performed while the table is in the vertical position in the vertical direction, the adhesive adheres to the member to be adhered and the progress of the film member is prevented. There is a possibility that there is a problem that the tip end of the film member in the traveling direction cannot reach the starting end of the sticking member with high precision. In order to prevent such a problem, when performing the initial alignment operation of the film member, the table is temporarily lowered (retracted) in the downward direction from the vertical reference position. Moreover, it is preferable to set it as the predetermined timing until the sticking operation|movement of a film member starts, and it is set to the timing which is almost the same as that after the initial setting operation|movement of a film member ends, or the initial setting operation of a film member ends.

[4] In the film member pasting apparatus of the present invention, it is preferable that the folding portion of the peeling portion is an edge portion.

As described above, by forming the folding portion of the peeling portion as an edge portion, the peeling operation when peeling the release film from the film member can be reliably performed. In addition, when the folding portion of the peeling portion is an edge portion, the release film becomes more fragile and the folding portion of the peeling portion is liable to wear, but even when the folding portion of the peeling portion is an edge portion, it is applied to the release film. Breakage of the release film can be suppressed by reducing the tension. In addition, wear of the folding portion can be suppressed as the release film is rubbed at the folding portion of the peeling portion. Moreover, the edge part can illustrate a wedge-shaped edge part, for example.

[5] In the film member attaching apparatus of the present invention, it is preferable that a feeder is provided between the clamper and the tension imparting portion to perform the above-mentioned "first alignment operation of the film member".

By providing such a feeder, it is possible to perform the initial alignment operation of the film member from which the release film has been peeled. Thereby, the front-end|tip part of the advancing direction of a film member can reach|attain the start-up end part of a to-be-attached member.

[6] In the film member attaching apparatus of the present invention, the film member supply mechanism portion further includes a camera provided so as to be capable of imaging a predetermined portion of the film member, and the control device is based on photographing data from the camera. It is preferable to further have a feeder control function that monitors the position of the predetermined portion of the film member and controls the feeder to perform the "first alignment operation of the film member".

Thereby, it is possible to perform the first alignment operation of the film member with high precision. Thereby, the front-end|tip part of the advancing direction of a film member can reach the starting-end|tip of the sticking member with high precision.

[7] In the film member attaching apparatus of the present invention, it is preferable that a predetermined portion of the film member is a rear end in the traveling direction of the film member.

As described above, by providing the camera with a camera member capable of imaging the rear end of the moving direction of the film member (the film member that is currently attached to the object), a space for installing the camera can be provided. This is because, at the present time, in order to photograph the front end of the film member which is affixed to the affix, there is no space in the space for installing the camera because a pressing roll or the like exists in the vicinity of the front end of the film member. to be.

[8] In the film member attaching apparatus of the present invention, the film member supply mechanism portion has a guide surface for guiding the progress of the film member from which the release film is peeled by the peeling unit, and adhesive is attached to the guide surface. It further has a guide member which is subjected to non-adhesive surface processing, and the guide member has an end portion of the guide member as an edge, and the guide surface is at an acute angle with respect to the member to be joined. , It is preferable that the starting end of the affixed member is positioned on the extension of the guide surface.

In this way, a guide member for guiding the progress of the film member is provided on the front side of the peeling portion. In addition, since the non-adhesive surface processing is applied to the guide surface of the guide member, the adhesive surface of the film member can be prevented from adhering to the guide surface of the guide member, and the film member is attached to the guide surface of the guide member. You can proceed smoothly.

In addition, the guide member is such that the tip end of the guide member is an edge, and the guide surface is at an acute angle with respect to the member to be joined, and the starting end of the abutment member is positioned on the extension of the guide surface. Since it is provided, it is possible to make the distance between the tip end of the guide member and the starting end of the affixed member as narrow as possible, and to make the step between the tip end of the guide member and the abutting end of the affixed member as small as possible. Can. Thereby, the distance until the front end of the film member in the traveling direction reaches the starting end of the affixed member can be shortened, and the film member is bent by its own weight until it reaches the affixed starting end. It can be prevented from being thrown away. Thereby, the front-end|tip part of the advancing direction of the film member advancing a guide surface can reach the affixing start end of a to-be-member member with high precision.

In addition, since the guide member is provided so that the abutting end of the abutting member is positioned on the extension of the guide surface, this also leads the abutting end of the abutting member to the leading end of the film member advancing the guide surface. Can be reached with high precision. In addition, that "the front end part of a guide member becomes an edge" means that the front end part may have an acute angle, for example, and the front end part may be made into a thin plate shape.

[9] In the film member pasting apparatus of the present invention, it is preferable that the guide surface has conductivity and is electrically grounded.

As described above, since the guide surface has electrical conductivity and is electrically grounded, even when static electricity is charged to the film member, static electricity charged to the film member can be removed. Thereby, it becomes difficult for dust and dust to adhere to the film member, and when performing the operation of attaching the film member to the member to be adhered, the film member can be adhered to the member to be adhered with high precision. In addition, when the member to be adhered to which the film member is attached is sent to the next step, static electricity can be prevented from being sent to the next step while being charged.

In particular, even when static electricity is charged on the adhesive surface (the surface on which the adhesive is applied) of the film member, the static electricity charged on the adhesive surface can be reliably removed by contacting the adhesive surface of the film member with a conductive guide surface. have. Thereby, when sending the to-be-attached member with the film member stuck to the next process, it is possible to prevent the static electricity from being charged between the to-be-attached member and the film member from being sent to the next step. If static electricity is charged between the member to be adhered and the film member, static electricity cannot be easily removed. For this reason, it is very effective as a countermeasure against static electricity to be able to reliably remove static electricity charged on the adhesive surface only by making the adhesive surface of the film member contact the conductive guide surface.

[10] In the film member pasting apparatus of the present invention, the film member supplying mechanism part further has a pressing roll for pressing the leading end of the film member in the advancing direction of the affixing member to the abutting start end of the film member, wherein the pressing roll is , It is preferable that the plurality of pressing rolls have a configuration in which they are stacked in a plurality of stages, and that the respective rotational axes of the plurality of pressing rolls are provided in a direction along the side of the leading end of the film member.

Since it has a pressing roll which presses the distal end of the film member in the advancing end of the affixed member, the film member can be reliably positioned at the apex start end of the affixed member. In addition, when the pressing roll has such a configuration, it is possible to reliably press the leading end portion of the film member along the side of the leading end portion of the traveling direction. In particular, when the length in the width direction of the film member (length along the rotation axis of the pressing roll) is long, the leading end portion of the film member can be pressed with a uniform pressing force over the entire width direction, and the leading end portion of the film member Can be surely pressed.

[11] In the film member attaching apparatus of the present invention, it is preferable that, among the plurality of pressing rolls, the diameter of the pressing roll located on the side in contact with the film member is set to a diameter smaller than the diameter of other pressing rolls. Do.

By setting the diameter of the pressing roll located on the side in contact with the film member in this way, even if the gap between the tip end portion of the guide member and the starting end of the affixed member member is narrow, the pressing roll has a small diameter. Without contact, the tip of the film member in the traveling direction can be reliably pressed. In addition, since it is also possible to prevent warping of the press roll having a small diameter, it is possible to press the distal end of the film member in the traveling direction with a uniform pressing force over the entire width direction of the film member.

[12] In the film member pasting device of the present invention, it is preferable that the tension imparting portion is a dancer roll.

When the tension imparting portion is a dancer roll, tension can be applied to the release film, and at the time of first fitting of the film member and at the time of attaching the film member, each of the first acting of the film member or the attaching motion of the film member , The winding operation of the release film by the winding roll does not need to be synchronized, and each operation can be performed independently.

[13] In the film member attaching apparatus of the present invention, the film member has a long sheet shape, and a tear line is provided by leaving the release film every predetermined length along the longitudinal direction of the long sheet-like film member, and the peeling portion is provided. When the release film is peeled off, it becomes a fragmented film member, and it is preferable that the fragmented film member is affixed to the abutment member.

When the film member has such a configuration, the operation of attaching the film member to the individual member to be joined can be continuously performed.

[14] In the film member attaching apparatus of the present invention, the film member is a polarizing film used in a liquid crystal panel or a protective film or an electromagnetic shielding film used in an electronic device, and the member to be joined is used in the liquid crystal panel It is preferable that it is a glass substrate or a synthetic resin substrate, or an electronic circuit board used for electronic equipment.

According to the film member pasting device of this aspect, a polarizing film or a protective film used for a liquid crystal panel is adhered to a glass substrate or a synthetic resin substrate used for a liquid crystal panel with high precision, or an electromagnetic wave shield film used for an electronic device is attached to an electronic device. Since the electronic circuit board to be used can be attached with high precision, a high-quality liquid crystal panel or electronic device can be manufactured.

[15] In the film member attaching method of the present invention, the film member is advanced while peeling the release film from the film member on one side of which is an adhesive surface and the release film is adhered to the adhesive surface so as to be peelable. , After performing the "first alignment operation of the film member" for reaching the starting end of the film member from which the release film has been peeled, to reach the starting end of the film member, the leading end of the film member in the traveling direction A film performed by the film member attaching device to perform a "film member affixing operation" in which the film member is affixed to the member to be adhered while the release film is peeled off from the starting end of the affix while being pressed against the affix starting end of the member. It is a member affixing method, and the said film member affixing apparatus is a table which loads the said to-be-attached member, the film member supply mechanism part which supplies the said film member, and the said film member in order to perform the said "first fitting operation of a film member." A control device having a film member initial alignment control function for controlling the supply mechanism portion, and a patch control function for relatively moving at least one of the film member supply mechanism portion and the table in order to perform the "sticking operation of the film member" The film member supply mechanism portion has a folding portion that redirects the release film in a direction substantially opposite to the direction in which the film member travels, and the film member supply mechanism portion in a state in which the release film is switched in the folding portion. The release film advancing mechanism portion has a peeling portion for peeling a release film from the film member by moving at least one of the tables relatively, and a release film advancing mechanism portion for advancing the release film which has been diverted from the folding portion. The tension film is provided between the tension-imparting portion and the peeling portion to provide tension along the direction in which the release film is propagated to the release film, which has been diverted, and performs the "sticking operation of the film member". In some cases, the above release The film is clamped at a predetermined position between the tensioning part and the peeling part, and the release film from the film member is actively synchronized with the "sticking operation of the film member" between the clamped position and the peeling part. A sticking/peeling synchronous mechanism for performing peeling operation is provided, and when performing the "sticking operation of the film member", the release film is clamped at a predetermined position between the tension applying portion and the peeling portion, and the clamped portion is clamped. Between the position and the peeling portion, it is characterized in that an operation of peeling the release film from the film member by actively synchronizing with the "sticking operation of the film member" is performed.

According to the film member pasting method of this invention, the effect similar to the film member pasting apparatus of this invention described in said [1] is obtained. Moreover, also in the film member pasting method of this invention, it is preferable to have the characteristics similar to the film member pasting apparatus of this invention described in said [2]-[14].

The film member pasting device 1 according to the embodiment advances the film member while peeling off the release film from the film member on which the release film is peelably affixed to the adhesive surface, and the direction in which the film member releases the release film After performing the ``first alignment operation of the film member'' to reach the starting end of the affixed member, the starting end of the affix is started while the tip of the moving direction of the film member is pressed against the affixed starting end of the affixed member It is a film member pasting device which performs the "attachment operation|movement of a film member" which sticks a film member to a to-be-attached member while peeling a release film.

In addition, the film member is affixed to the film member affixing surface starting from the affixing end of the affixed member on the film member affixing surface, but in this specification, the "film member affixing surface" is omitted, eg For example, "the film member is affixed to the starting end of the affixed member as a starting point" or simply "film member is affixed to the affixed member".

In addition, in the film member pasting apparatus 1 which concerns on Embodiment 1, it is assumed that the film member is a polarizing film used for a liquid crystal panel, and that the member to be adhered is a glass substrate used for a liquid crystal panel. Here, the size of the film member (polarizing film) is not particularly limited, but in the film member attaching device 1 according to the first embodiment, the member to be joined (glass substrate) is, for example, a long side (vertical) 1500 It is assumed to be a relatively large size of about ㎜×short side (horizontal) 900 mm, and a size that can be attached with a margin of about 5 mm from each of the horizontal and vertical sides of the member having such a size ( For example, it is assumed that it has a long side (length) of 1490 mm × a short side (width) of about 890 mm).

In general, the liquid crystal panel has a configuration in which a polarizing film having a polarization direction orthogonal to each other is attached to two glass substrates (surface-side glass substrate and rear-side glass substrate) provided on the front side and the back side of the liquid crystal layer. However, in the film member pasting device 1 according to the first embodiment, a case where a polarizing film is attached to a glass substrate used for one of the front side glass substrate and the back side glass substrate will be described. Hereinafter, the film member attaching device 1 according to the embodiment will be described in detail.

In addition, in the following description, "film member" may be referred to as "polarizing film", and "member to be pasted" may be referred to as "glass substrate." For this reason, in the following description, when "polarizing film" is indicated, the polarizing film refers to a "film member", and when it is indicated as "glass substrate", the glass substrate is "pasted member" 」.

1 is a view for explaining the film member pasting device 1 according to the first embodiment. 1 is a figure which shows typically the film member pasting apparatus 1 which concerns on 1st Embodiment. The film member pasting device 1 according to the first embodiment is a film member for supplying a table 100 on which the glass substrate 10 is loaded and a polarizing film 30 (film member), as shown in FIG. 1. A supply mechanism 200 and a control device 300 having a control function for controlling each component of the film member pasting device 1 according to the embodiment are provided. In addition, the detailed structure and operation|movement of these tables 100 and the film member supply mechanism part 200 are mentioned later. In addition, the control function of the control device 300 will also be described later.

Further, in the film member attaching device 1 according to the first embodiment, the film member supply mechanism 200 is fixed, and the table 100 is moved (moved in the xx' direction along the x-axis), thereby providing a polarizing film ( It will be described assuming that 30) is attached to the glass substrate 10.

The film member supply mechanism part 200 includes a peeling part 210 having a folding part 211 that changes the release film 40 in a direction substantially opposite to a direction in which the polarizing film 30 is traveling, and a peeling part 210 ) Has a release film advancing mechanism portion 220 that advances the release film 40 that has been diverted from the folding portion 211 in the release film advancing direction. In addition, "release film advancing direction" is a direction (arrow x direction) in which the release film 40 switched in direction by the peeling part 210 advances. In addition, the folding portion 211 is an edge portion, and the edge portion may have a slightly rounded portion at the tip.

The peeling part 210 is in a state in which the release film 40 is reversed in the direction substantially opposite to the direction in which the polarizing film 30 proceeds by the folding part 211, in this case, the table 100 moves By doing so, it is operated to release the release film 40 from the polarizing film 30.

In addition, the film member supply mechanism part 200 is provided with a guide member 230 having a guide surface 231 for guiding the progress of the polarizing film 30 from which the release film 40 has been peeled off by the peeling part 210. , When the tip portion 30a (hereinafter sometimes referred to as the tip portion 30a) in the traveling direction of the polarizing film 30 reaches the abutting end 10a of the glass substrate 10, the abutting starting end ( In 10a), the pressing roll 240 pressing the tip portion 30a of the polarizing film 30 against the abutment starting end 10a and a predetermined portion (to be described later) of the polarizing film 30 can be imaged. 250.

In addition, the film member supply mechanism portion 200, in addition to the above-described components, the polarization film 30 (the polarization film 30 in the state where the release film 40 is affixed) is bent to advance to advance the bending roll 261 , 262). In addition, there are also a delivery mechanism portion for transmitting the polarizing film 30 (the polarizing film 30 in which the release film 40 is affixed) and a dancer roll provided in the middle portion of the traveling path, but these illustrations are omitted. .

By the way, in FIG. 1, while the polarizing film 30 is in the state (it is in the state where it is first-fit), it reached the abutting end 10a of the glass substrate 10, and the table 100 is, It shows a case where the polarizing film 30 is moved to a position where the operation of affixing the polarizing film 30 starting from the abutting end 10a of the glass substrate 10 is started.

Moreover, when explaining the film member pasting apparatus 1 which concerns on embodiment, the front end part 30a of the moving direction of the polarizing film 30 from which the release film 40 was peeled is the starting end of the pasting of the glass substrate 10 In some cases, the operation for reaching (10a) is referred to as a "first alignment operation of the polarizing film 30". In addition, after the first alignment operation of the polarizing film 30 is performed, the abutting starting end 10a while pressing the leading end 30a of the traveling direction of the polarizing film 30 with the abutting starting end 10a of the glass substrate 10 ), the operation of attaching the polarizing film 30 to the glass substrate 10 while peeling off the release film 40 is sometimes referred to as “attaching operation of the polarizing film 30 ”.

In addition, in FIG. 1, although the case where the pressing roll 240 is in a position away from the tip portion 30a of the polarizing film 30 is illustrated, when performing the attaching operation of the polarizing film 30, The pressing roll 240 is in a state where the tip portion 30a of the polarizing film 30 is pressed. In addition, a position in the vertical direction along the z-axis of the table 100 when the attaching operation of the polarizing film 30 is performed is referred to as a "reference position in the vertical direction". The vertical reference position is shown as the height h from the surface of the stage 50. For this reason, hereinafter, the reference position in the vertical direction is referred to as "reference position h in the vertical direction".

In addition, in FIG. 1, after the polarizing film 30 (the polarizing film 30 in which the release film 40 is affixed) is bent in a downward direction at a large angle by the progressing auxiliary roll 261, , It is bent to a predetermined angle (referred to as 30 degrees in the film member attaching apparatus 1 according to the embodiment) with respect to the xy plane by the progressing auxiliary roll 262 to reach the peeling portion 210. Further, the angle is not limited to 30 degrees, and can be appropriately set to an optimal angle.

As described above, the polarizing film 30 (the polarizing film 30 in which the release film 40 is affixed) is on the progressing path of the polarizing film 30, such as progressing assist rolls 261 and 262. Although the traveling direction is bent in the downward direction or is inclined, the traveling direction of the polarizing film 30 is generally a direction from the right side of the city to the left along the x-axis (arrow x'direction). . For this reason, in this specification, when explaining the advancing direction of the polarizing film 30, it is described as "the arrow x'direction along the x-axis" or "the direction from the right of the city to the left".

In addition, inside the broken-line frame A in FIG. 1 is an enlarged cross-sectional view of the polarizing film 30 (polarizing film 30 in which the release film 40 is attached). The configuration of the polarizing film 30 (polarizing film 30 in which the release film 40 is attached) will be described with reference to FIG. 2.

FIG. 2 is a view for explaining the polarizing film 30 (polarizing film 30 in which the release film 40 is attached). In Fig. 2, Fig. 2(a) is a plan view, and Fig. 2(b) is a side sectional view. In addition, FIG. 2 is a schematic diagram, and the thickness and the like are exaggerated.

As shown in FIG. 2, the polarizing film 30 has a long shape, and the long release film 40 is attached so that peeling is possible. The polarizing film 30 is provided with a perforation line for each predetermined length, leaving the release film 40 so as to be individualized into sizes corresponding to the individual glass substrates 10 (see FIG. 1) to be attached. For example, in the case where the long side of the glass substrate 10 (referred to as 1500 mm) is mounted on the table 100 along the x-axis, for each long side (referred to as 1490 mm) of the polarizing film 30, Leaving the release film 40, and cutting lines C1, C2,… Has been prepared.

In addition, since the adhesive 31 is applied to the polarizing film 30, when the release film 40 is peeled from the polarizing film 30, an adhesive ( 31) will be exposed. In addition, the side where the adhesive 31 is applied in the polarizing film 30 is referred to as an “adhesive surface”.

In addition, in the long-shaped polarizing film 30 shown in FIG. 2, when the polarizing films corresponding to individual glass substrates are separately described, the individual polarizing films are sequentially ordered from the left in FIG. 2. It demonstrates like 1st polarizing film 30 and 2nd polarizing film 30,.... In addition, perforations C1, C2,… In the case of the individual polarizing film 30, it may become a rear end part (hereinafter abbreviated as a rear end part) in a traveling direction, or may be a front end part. For example, when attention is paid to the first polarizing film 30, the perforation line C1 becomes the rear end 30b of the first polarizing film 30, and also pays attention to the second polarizing film 30. In this case, the perforation line C1 becomes the tip portion 30a of the second polarizing film 30.

1, individual components of the film member pasting device 1 according to the embodiment will be described in more detail.

The table 100 is capable of reciprocating on the guide rail 60 attached to the stage 50 in the direction of the arrow x-x' along the x-axis. In addition, the table 100 has a slider 110 capable of traveling through the guide rail 60 and a table body portion 120 provided on the slider 110. The table body portion 120 is to load the glass substrate 10 (member to be covered). The table body portion 120 is capable of reciprocating along the x-axis along with the slider 110, and with respect to the slider 110, moving along the y-axis, rotating on the xy plane, and moving up and down along the z-axis. It is possible.

For this reason, in the table 100, the y-axis direction position adjustment mechanism which enables position adjustment along the y-axis of the table main-body part 120, and the rotation angle adjustment of the table main-body part 120 on the xy plane are possible. A rotation angle adjustment mechanism to be performed, and a lifting mechanism that enables elevation of the table body portion 120 along the z-axis are provided. Since various mechanisms can be employed for these, the y-axis position adjustment mechanism, the rotation angle adjustment mechanism, and the lifting mechanism, illustration and description of each of these mechanisms is omitted. In addition, the reciprocating movement control along the x-axis of the slider 110, the position adjustment control in the y-axis direction of the table body portion 120, the rotation angle adjustment control, and the elevation control are performed as control functions of the control device 300.

Further, as described above, the table 100 has a slider 110 and a table body portion 120, but in this specification, these are collectively described as "table 100". Therefore, for example, that the table 100 moves along the x-axis means that, in reality, the slider 110 and the table body portion 120 integrally move along the x-axis, and the table 100 moves along the z-axis. Therefore, in order to elevate, in reality, the table main body 120 is elevating along the z axis with respect to the slider 110.

In addition, in the film member attaching apparatus 1 according to the embodiment, the slider 110, the table body portion 120, the stage 50, and the guide rail 60 are made of metal, such as iron, for example. do.

Next, the release film advancing mechanism portion 220 will be described.

The release film advancing mechanism portion 220 advances the release film 40 that has been diverted from the peeling portion 210 in a direction substantially opposite to that of the polarizing film 30 (release film advancing direction).

The release film advancing mechanism portion 220 is the release film 40 that is switched from the affixing/peeling synchronization mechanism portion 221 (described in detail later) and the folding portion 211 of the peeling portion 210. A tension imparting portion (referred to as a dancer roll 222 in the film member pasting device 1 according to the embodiment) and a plurality of advancing portions that provide tension along the direction in which the film 40 is advancing (release film advancing direction) The auxiliary roll (for example, the progressing auxiliary rolls 223 and 224), the feeder 225 for performing the first alignment operation of the polarizing film 30, and the downstream side of the dancer roll 222 (in the direction of release film progression) It is provided on the front side), and a winding roll (not shown) for winding the release film 40 is provided.

The affixing/peeling synchronous mechanism portion 221 is disposed between the dancer roll 222 and the peeling portion 210 as a tension imparting portion. And when performing the pasting operation of the polarizing film 30, the release film 40 is clamped at a predetermined position between the dancer roll 222 and the peeling part 210, and the clamped position and the peeling part 210 In the meantime, the operation of peeling the release film 40 from the polarizing film 30 is performed by actively synchronizing with the attaching operation of the polarizing film 30. In addition, in the following description, the operation of peeling the release film 40 from the polarizing film 30 may be abbreviated as the "release action of the release film 40".

As a specific component of the affixing/peeling synchronous mechanism part 221, it is provided at a predetermined position between the dancer roll 222 and the peeling part 210, and the release film 40 is provided with the dancer roll 222 and the peeling part 210. ) Is located between the clamper 221c clamped at a predetermined position between the clamper 221c and the peeling part 210, and is provided on the film member supply mechanism part 200 side, and the peeling part 210 In the first folding roll (221a) and the clamper (221c) and the first folding roll (221a) to switch the direction to advance the release film 40 peeled in the direction substantially the same as the traveling direction of the polarizing film (30) Located in between, and also installed on the side of the table 100, the direction to advance the release film 40, which is redirected in the first folding roll 221a, in a direction substantially opposite to the traveling direction of the polarizing film 30 It has a second folding roll 221b to switch.

Since the 1st folding roll 221a is provided in the film member supply mechanism part 200 side, even if the table 100 moves, the position will not change. On the other hand, since the second folding roll 221b is provided on the table 100 side (specifically, the slider 110 of the table 100), xx' of the table 100 (the slider 110) It moves with the movement of direction.

In addition, the clamper 221c clamps the release film 40 when performing the operation of attaching the polarizing film 30 to the glass substrate 10, but the feeder 225 allows the polarizing film 30 to be clamped. When performing the first-fit operation, the clamp of the release film 40 is released. The specific operation of the affixing/peeling synchronization mechanism unit 221 configured as described above will be described later. In addition, the clamp/clamp release operation of the release film 40 by the clamper 221c and the first alignment operation of the polarizing film 30 by the feeder 225 were performed as one of the control functions of the control device 300. All.

The feeder 225 is provided between the clamper 221c and the progress assist roll 223, and the front end portion 30a of the polarizing film 30 from which the release film 40 has been peeled off is affixed to the glass substrate 10. It has a function for reaching the stage 10a, that is, a function for performing the first alignment operation of the polarizing film 30. Further, the feeder 225 has a plurality of clampers 226 for clamping the release film 40, and is capable of reciprocating in the direction of the arrow x-x' along the x-axis.

Control of the feeder 225 is performed as one of the control functions of the control device 300. In this case, the control device 300 monitors the position (for example, the position along the x-axis) of a predetermined portion of the polarizing film 30 (for example, the rear end 30b) based on the photographing data from the camera 250 , The feeder 225 is controlled so that the leading end 30a of the polarizing film 30 reaches the abutting end 10a of the glass substrate 10.

As an example of the control of the feeder 225 by the control device 300, for example, the control device 300 is a polarizing film that is attached to the object at the present time based on photographing data from the camera 250. The position of the rear end 30b (referred to as the first polarizing film 30) (the perforation line C1 between the first polarizing film 30 and the second polarizing film 30) is monitored, and the rear end 30b ) The feeder 225 is operated until the position of the cutting line C1 reaches the target position.

Specifically, the position of the rear end portion 30b of the polarizing film 30 when the tip portion 30a of the polarizing film 30 has reached the abutting end portion 10a of the glass substrate 10 accurately is "target." Position” in advance, and the control device 300 until the position of the rear end portion 30b (cut line C1) of the first polarizing film 30, which is currently subject to attachment, reaches the target position. The release film 40 is advanced in the release film traveling direction. Thereby, the first alignment of the said 1st polarizing film 30 can be performed with high precision. That is, the tip portion 30a of the polarizing film 30 can be reached with high precision to the abutting end portion 10a of the glass substrate 10.

Then, when the position of the rear end portion 30b (cut line C1) of the polarizing film 30 reaches the target position, the clamping action of the feeder 225 relative to the release film 40 is released, and the feeder 225 is returned to the original position. Control to return to the position of.

In addition, in the film member pasting device 1 according to the embodiment, the camera 250 sets the position of the rear end part 30b (cut line C1) of the first polarizing film 30 that is the pasting target at the present time. Although this is to be monitored, it is necessary to install the camera 250 at a position where, for example, the position of the tip portion 30a of the first polarizing film 30 that is to be affixed at the present time is monitored. This is because there is no room in the space for installing the camera 250 due to the presence (see FIG. 1). However, if there is room in the space for installing the camera 250, the position of the tip portion 30a of the first polarizing film 30, which is currently subject to sticking, may be monitored.

Subsequently, the guide member 230 and the pressing roll 240 will be described with reference to FIG. 3.

3 is a view for explaining the guide member 230 and the pressing roll 240. 3(a) is an enlarged view of the pressing roll 240 of FIG. 1 and the range enclosed by the dashed line frame B in FIG. 1, and FIG. 3(b) shows the z axis of FIG. 3(a). Therefore, it is the view (plan view) seen from above. In addition, in FIG. 3B, illustration of the pressing roll 240 and the like shown in FIG. 3A is omitted.

First, the guide member 230 will be described. The guide member 230 has a guide surface 231 that guides the progress of the polarizing film 30 from which the release film 40 has been peeled off. In addition, since FIG. 3 is a schematic view similar to FIG. 1, the installation structure of the guide member 230 is not shown, but the guide member 230 is a support member (not shown) installed vertically from the stage 50. ). The supporting member is also made of metal such as iron, for example. In addition, the guide member 230 is formed of, for example, a metal such as stainless steel, and the guide surface 231 (the side contacting the polarizing film 30) of the guide member 230 is non-adhesive. It is supposed to have. That is, the non-adhesive surface processing having non-adhesiveness is performed on the guide surface 231 of the guide member 230 while maintaining conductivity. As described above, the reason why the non-adhesive surface processing is performed on the guide surface 231 is that one surface of the polarizing film 30 is an adhesive surface coated with an adhesive 31 (see FIG. 2 ).

That is, since the adhesive 31 is applied to the adhesive surface of the polarizing film 30 in a state where the release film 40 is peeled off, the adhesive 31 is attached to the guide surface 231 of the guide member 230. If the non-adhesive surface processing is not performed, the adhesive 31 of the polarizing film 30 is attached to the guide surface 231 of the guide member 230, so that the polarizing film 30 is the guide member 230 This is because it cannot proceed smoothly along the guide surface 231 of.

The non-adhesive surface processing that prevents the adhesion of the adhesive 31 is a known technology, and for example, a surface processing technology called "Tosical (registered trademark) S coating processing" can be employed. The polarizing film from which the release film 40 was peeled off by performing such surface processing (Toshiko (registered trademark) S coating film formation processing/Toshiko Co., Ltd.) on the guide surface 231 of the guide member 230 The adhesive surface of 30) is not attached to the guide surface 231 of the guide member 230, and the polarizing film 30 can be smoothly advanced to the abutting end 10a of the glass substrate 10. As the S (registered trademark) S, for example, those of the UNA-300 series (UNA-310-X10), UNA-800 series, TS-1000 series, TS-1080 series, and TS-1310 series can be suitably used. .

The thickness of the coating film of Tosical (registered trademark) S can be suitably used, for example, from 1 µm to 200 µm, preferably from 3 µm to 150 µm. Before forming the coated film of Tosical (registered trademark) S, an uneven structure may be formed on the guide surface 231 of the guide member 230. As the average surface roughness of the concavo-convex structure in this case, those having a size of 2 µm to 15 µm can be suitably used.

By performing such non-adhesive surface processing on the guide surface 231 of the guide member 230, the adhesive surface of the polarizing film 30 from which the release film 40 has been peeled off is guide surface 231 of the guide member 230. Without being attached to, the polarizing film 30 can be smoothly advanced to advance to the abutting end 10a of the glass substrate 10. This surface treatment is a non-adhesive surface treatment that does not impair conductivity. Therefore, the guide surface 231 is said to maintain conductivity even after non-adhesive surface processing is performed. For this reason, the conductivity of the guide surface 231 is not damaged. In addition, the guide surface 231 is electrically grounded. That is, the guide surface 231 has conductivity and is grounded. As described above, the reason why the guide surface 231 is conductive and grounded will be described later.

In addition, in the film member pasting device 1 according to the embodiment, the guide member 230 is formed in a triangular block shape, and the tip portion 232 of the guide member 230 is an edge, and the guide is The surface 231 is disposed at an acute angle with respect to the glass substrate 10. In addition, hereinafter, the tip portion 232 of the guide member 230 is referred to as a “guide member tip portion 232 ”.

In the guide member 230 configured as described above, as shown in FIG. 3A, the starting end 10a of the glass substrate 10 passes through the pressing point P of the pressing roll 240. When the position on the repair line L (referred to as the starting position of affixing operation) is reached, the abutting starting end 10a of the glass substrate 10 is provided on the extension of the guide surface 231.

In addition, the guide member 230 is a position along the z-axis, which is a position that does not contact the glass substrate 10 loaded on the table 100, and further includes a guide member tip portion 232 and a glass substrate 10. It is installed at a position where the step difference of is small. In addition, "pressing point P" of the pressing roll 240 refers to a point where a pressing force is applied to the polarizing film 30 when the pressing roll 240 performs an operation of pressing the polarizing film 30. It is assumed.

Here, the inclination angle of the guide surface 231, that is, the angle θ formed between the guide surface 231 and the xy plane (the angle θ formed between the guide surface 231 and the glass substrate 10 loaded on the table 100) In the film member pasting device 1 according to the embodiment, it is assumed that it is set at 30 degrees. In addition, the angle θ formed between the guide surface 231 and the glass substrate 10 is not limited to 30 degrees, and the front end portion 30a of the polarizing film 30 is the starting end portion 10a of the glass substrate 10 You just need to be able to reach it smoothly.

In addition, the installation position of the guide member 230 includes the tip end portion 232 of the guide member 230 and the glass substrate (when the starting end 10a of the glass substrate 10 reaches the starting position of the sticking operation) It is preferable that the spacing (distance along the x-axis) d of the abutment starting end 10a of 10) is made as narrow as possible. In addition, although the distance d differs depending on the inclination angle of the guide surface 231 and the like, in the film member attaching device 1 according to the embodiment, the interval d is set to 15 mm. The distance d is not limited to 15 mm, and can be set to an optimum value by an angle with respect to the xy plane of the guide surface 231 of the guide member 230, the material and size of the polarizing film 30, and the like.

In addition, the guide member 230 is electrically grounded (earth). Specifically, as described above, the guide member 230 is provided on a support member (not shown) that is vertically installed on the stage 50 (see FIG. 1 ), and these support members and the stage 50 are Since all are made of metal, the guide member 230 is supposed to be electrically grounded (earthed) through the support member and the stage 50. For this reason, the guide surface 231 of the guide member 231 is inevitably grounded.

In addition, since the above-described FIG. 1 is a view schematically showing the film member attaching device 1 according to the first embodiment, the specific installation state of the stage 50 is not shown, but the stage 50 is a factory or the like. It is assumed that the floor is electrically grounded (earthed). Thereby, the guide member 230 includes the guide surface 231 and is electrically grounded (earthed) through the support member and the stage 50.

As described above, in the guide member 230, since the guide member tip portion 232 is an edge, the gap between the guide member tip portion 232 and the abutment starting end 10a of the glass substrate 10 is as much as possible. In addition to being able to be narrowed, the level difference between the tip end portion 232 of the guide member and the starting end portion 10a of the glass substrate 10 can be made as small as possible. Thereby, it is possible to shorten the distance until the tip portion 30a of the polarizing film 30 (film member) reaches the abutting start end 10a of the glass substrate 10 (piece member). It can be prevented from being warped by its own weight until 30 reaches the abutment starting end 10a. Thereby, the tip part 30a of the polarizing film 30 advancing the guide surface 231 can be reached with high precision to the apex start end 10a of the glass substrate 10.

In addition, since the guide member 230 is provided so that the abutting end 10a of the glass substrate 10 is positioned on the extension of the guide surface 231, the guide surface 231 is also advanced by this. The leading end 30a of the polarizing film 30 can be reached with high precision to the starting end 10a of the glass substrate 10.

In addition, the guide member 230 is formed of a metal such as stainless steel, and the guide surface 231 of the guide member 230 has electrical conductivity and is electrically grounded (earthed). For this reason, even when static electricity is charged in the polarizing film 30, static electricity charged in the polarizing film 30 can be removed. This makes it difficult for dust and dust to adhere to the polarizing film 30 and, when performing the operation of attaching the polarizing film 30 to the glass substrate 10 as a member to be adhered, the film member with high precision. It can be attached to the glass substrate 10. In addition, when the glass substrate 10 to which the polarizing film 30 is attached is sent to the next process, static electricity can be prevented from being sent to the next process while being charged.

In particular, even when static electricity is charged on the adhesive surface of the polarizing film 30 (specifically, the adhesive 31 applied to the polarizing film 30), the adhesive surface of the polarizing film 30 (adhesive 31) The surface on which is coated) is in contact with the conductive guide surface 231, so that static electricity charged on the adhesive surface (adhesive 31) can be reliably removed. Thereby, when the glass substrate 10 to which the polarizing film 30 is attached is sent to the next process, static electricity is charged between the glass substrate 10 and the polarizing film 30 and is sent to the next process in the same state. It can be prevented from being thrown away. When static electricity is charged between the glass substrate 10 and the polarizing film 30, since the static electricity cannot be easily removed, the adhesive surface of the polarizing film 30 only contacts the conductive guide surface, The fact that static electricity charged on the adhesive surface can be reliably removed is very effective as a countermeasure against static electricity.

Next, the pressing roll 240 will be described. The pressing roll 240 has a configuration in which two rolls 241 and 242 having different diameters overlap two stages along the water line L (a configuration of two-stage overlapping), as shown in Fig. 3(a). , Each of the rotating shafts 241a and 242a is provided to be in a direction along the tip portion 30a of the polarizing film 30 (direction along the y-axis). In the first pressing rolls 241 and 242, the respective rotating shafts 241a and 242a are rotatably installed on the pressing roll mounting member 243. Moreover, the press roll installation member 243 is provided in the film member supply mechanism part 200.

Here, of the two pressing rolls 241 and 242, the pressing roll 241 positioned on the side contacting the polarizing film 30 is referred to as a first pressing roll 241, and the other pressing roll 242 is a second In the case of the pressing roll 242, the diameter Φ1 of the first pressing roll 241 (see Fig. 3(a)) is set smaller than the diameter Φ2 of the second pressing roll 242. In the film member pasting device 1 according to the embodiment, the diameter Φ 1 of the first pressing roll 241 is about 10 mm. In this way, the reason why the first pressing roll 241 and the second pressing roll 242 are constituted by two-stage overlapping, and the diameter Φ1 of the first pressing roll 241 is greater than the diameter Φ2 of the second pressing roll 242 The reason for the small setting will be described later.

The pressing roll 240 (the first pressing roll 241 and the second pressing roll 242) configured as described above, along with the pressing roll mounting member 243, in the direction along the z axis (arrow zz' direction) When the film member attaching device 1 according to the embodiment is movable and does not perform the attaching operation of the polarizing film 30, a flat surface including the glass substrate 10 mounted on the table 100 ( It is deviated (positioned upward) with respect to the xy plane), and when performing the attaching operation of the polarizing film 30, it descends and performs the operation of pressing the polarizing film 30. The raising and lowering operation of the pressing roll 240 is performed as one of the control functions of the control device 300.

By the way, the diameter Φ1 of the first pressing roll 241 is smaller than the diameter Φ2 of the second pressing roll 242, and the second pressing roll 242 of a larger diameter is placed on the first pressing roll 241 of a smaller diameter. It is for the reason demonstrated next that it was made into the overlapped structure.

That is, when the glass substrate 10 reaches the starting position of the sticking operation, the distance d between the tip end portion 232 of the guide member and the sticking end 10a of the glass substrate 10 is as narrow as 15 mm as described above. This is because the first pressing roll 241 does not come into contact with the guide member 230 when the first pressing roll 241 is in the pressed state because of the gap.

That is, in order to prevent the first pressing roll 241 from contacting the guide member 230, it is necessary to make the diameter Φ1 of the first pressing roll 241 as small as possible. On the other hand, if the diameter of the first pressing roll 241 is made small, the pressing force for pressing the polarizing film 30 with only the first pressing roll 241 is the width direction of the polarizing film 30 (in this case, along the y axis. Width) There arises a problem that it may not be uniformly applied over the whole.

Specifically, the length of the polarizing film 30 in the width direction (direction along the y-axis in FIG. 3) is set to about 890 mm in this case. Thus, when the length of the width direction (the direction along the y-axis in FIG. 3) of the polarizing film 30 is about 890 mm long, the length (y-axis) along the rotation axis 241a of the 1st press roll 241 Length). Here, when the diameter Φ1 is small with respect to the length along the rotation axis 241a of the first pressing roll 241, warpage may occur, and when warpage occurs, the pressing force is not uniformly applied across the entire width direction. do. Thus, the first pressing roll 241 having a small diameter is such that the diameter Φ1 of the first pressing roll 241 is made as small as possible, while the pressing force by the pressing point P is uniformly applied over the entire width direction of the polarizing film 30. ) The second pressing roll 242 having a large diameter is stacked on top.

By setting the pressing roll 240 in such a configuration, even if the distance d between the guide member leading end portion 232 and the abutting starting end 10a of the glass substrate 10 is narrow to 15 mm, the first pressing roll 241 is the guide member. The polarizing film 30 can be reliably pressed without contacting the 230. In addition, the second pressing roll 242 prevents the bending of the first pressing roll 241, so that the polarizing film 30 can be reliably pressed with a uniform pressing force across the entire width direction (y-axis direction). In this way, the second pressing roll 242 functions as a backup roll for backing up the pressing force of the first pressing roll 241.

Next, the operation of the film member pasting device 1 according to the embodiment will be described.

4 is a diagram for explaining the operation of the film member pasting device 1 according to the embodiment.

FIG. 5 is a view for explaining the operation (continued operation in FIG. 4) of the film member attaching device 1 according to the embodiment.

Fig. 4A is a state before the affixing operation is started, and this state is referred to as this initial state. In this initial state, the table 100 is positioned at the left side of the city (start position) than the pressing roll 240 (the first pressing roll 241 and the second pressing roll 242). Further, in the initial state, on the table 100, a glass substrate 10 (referred to as the first glass substrate 10) that is the object to be joined at the present time is loaded at a predetermined position on the table 100. It is assumed. In addition, it is assumed that the amount of movement along the x-axis from the start position of the table 100, the position along the y-axis, the angle around the z-axis (angle on the plane), and the like are appropriately adjusted. In the initial state, it is assumed that the vertical position along the z-axis of the table 100 is the vertical reference position h.

In addition, the release film 40 is connected to a winding roll (not shown) having a winding-side tip (not shown) for winding the release film 40, and is a polarizing film (first polarized light) that is currently attached to the object. It is assumed that the tip portion 30a of the film 30) has reached the tip portion (folding portion 211) of the peeling portion 210. Further, in this initial state, the pressing roll 240 (the first pressing roll 241 and the second pressing roll 242) is a plane (xy) including the glass substrate 10 mounted on the table 100. Plane).

In the initial state shown in Fig. 4(a), first, the control device 300 controls the table 100 to advance in the right direction (arrow x direction) by a predetermined amount of movement along the x-axis. Thereby, the table 100 proceeds to the position shown in Fig. 4B (the starting position of the sticking operation). Specifically, the control device 300 x the table 100 so that the abutting end 10a of the first glass substrate 10 reaches a position facing the pressing point P of the pressing roll 240. It is controlled to move in the right direction (arrow x direction) along the axis. In addition, although the glass substrate used as the object to be adhered here is "first glass substrate 10", "first substrate" may be omitted and sometimes referred to as "glass substrate 10".

As described above, when the table 100 moves in the right direction (arrow x direction) along the x-axis, the abutting end 10a of the glass substrate 10 is positioned at a position facing the pressing point P of the pressing roll 240. To reach. In this state, the control device 300 performs the first alignment operation of the first polarizing film 30 by the film member initial alignment control mechanism of the control device 300, but the first polarization film 30 Before performing the initial search operation of the control device 300, the table lift control function of the control device 300 has the table 100 along the z-axis rather than the vertical position reference position h with respect to the lift mechanism. It is controlled to descend (retreat) by a predetermined amount Δh (see FIG. 4(b) ). In addition, although the polarizing film used as a sticking object here is "1st polarizing film 30", "1st" may be abbreviated and referred to as "polarizing film 30".

When the control device 300 performs such control, the table 100, as shown in Fig. 4 (b), the starting end 10a of the glass substrate 10, the pressing roll 240 It is the position opposing the pressing point P of, and it is set to the position descending by a predetermined amount Δh along the z-axis from the vertical reference position h in the vertical direction. The term "predetermined amount [Delta]h" herein refers to a glass substrate on which the front end portion 30a of the polarized film 30, which is first-fitted, is loaded on the table 100 when the first-fit operation of the polarizing film 30 is performed. It is sufficient as long as it is possible to reliably prevent the contact with (10), and for example, it may be about several millimeters to several ten millimeters. Moreover, this "predetermined amount (DELTA)h" is not specifically limited, It can be set to an optimal amount suitably.

As shown in FIG. 4(b), the abutment starting end 10a of the glass substrate 10 is a position facing the pressing point P of the pressing roll 240, and z is more than the reference position h in the vertical direction. In a state where the position is lowered by a predetermined amount Δh along the axis, the control device 300 performs the first alignment operation of the polarizing film 30 by the first member alignment control function of the control device 300. The feeder 225 is controlled.

Thereby, the feeder 225 clamps the release film 40 with a clamper 226 as shown in Fig. 4(c), and the release film 40 is released in a predetermined amount by the release film traveling direction. (Arrow x direction). When the control device 300 performs such control, the tip portion 30a of the polarizing film 30 from which the release film 40 has been peeled is located at a position facing the abutting end portion 10a of the glass substrate 10. To reach. That is, the first alignment operation of the polarizing film 30 is performed. However, at this point, since the table 100 is in the lowered state, the tip portion 30a of the polarizing film 30 does not come into contact with the abutting end portion 10a of the glass substrate 10. In addition, when performing the initial alignment operation of the polarizing film 30, the control device 300 releases the clamp of the release film 40 with respect to the clamper 221c of the affix/peel synchronization mechanism 221 Control.

Here, the first alignment operation of the polarizing film 30 will be described in detail. When the release film 40 is advanced by the feeder 225 in the release film advancing direction (arrow x direction) by a predetermined amount, the release film 40 is peeled off from the polarizing film 30 by the peeling part 210. At the same time, the polarizing film 30 from which the release film 40 has been peeled, proceeds through the guide surface 231 of the guide member 230, so that the tip portion 30a of the polarizing film 30 is the glass substrate 10. The position opposite to the abutment starting end 10a is reached (see Fig. 4(c)). However, at this time, since the table 100 is in a lowered (retracted) state, the forward end portion 30a of the polarizing film 30 in the advancing end 10a of the glass substrate 10 It is not in contact.

In addition, when the polarizing film 30 advances the guide surface 231 of the guide member 230, the guide film 231 of the guide member 230 is subjected to non-adhesive surface processing, and thus the release film 40 ) When the peeled polarizing film 30 proceeds to guide surface 231 of guide member 230, the adhesive surface of polarizing film 30 is not attached to guide surface 231 of guide member 230 , The polarizing film 30 can be smoothly progressed.

However, the control of the feeder 225 by the control device 300 as described above is performed based on the captured image data from the camera 250. As an example of control of the feeder 225 by the control device 300, as described above, the control device 300 is subject to attaching at the present time based on the photographing data from the camera 250. The position of the rear end 30b (cut line C1) of the polarizing film 30 (first polarizing film 30) is monitored, and until the position of the rear end 30b (cut line C1) reaches the target position , The feeder 225 is operated. Thereby, the front-end|tip part 30a of the polarizing film 30 reaches the affixing start-end 10a of the glass substrate 10. In this way, when the tip portion 30a of the polarizing film 30 reaches the abutting end portion 10a of the glass substrate 10, the control device 300 clamps the feeder 225 with respect to the release film 40 Control to release. Thereby, the feeder 225 returns to the initial state.

When the feeder 225 advances the release film 40 in the release film advancing direction, the dancer roll 222 performs an operation of descending by the amount the feeder 225 has moved. By providing such a dancer roll 222, the supply operation (first alignment operation) of the polarizing film 30 by the feeder 225 and the winding operation of the release film 40 by the winding roll (not shown) are synchronized. It is not necessary to take each, and each operation can be performed independently. The winding operation of the release film 40 by the winding roll (not shown) may be performed when the lower limit amount of the dancer roll 222 reaches a predetermined amount.

In addition, the dancer roll 222 functions not only during the initial alignment operation of the polarizing film 30 by the feeder 225, but also during the attaching operation of the polarizing film 30. That is, even in the operation of attaching the polarizing film 30, it is not necessary to synchronize the movement of the table 100 with the movement of the release film by the winding roll, and each operation can be performed independently. . For example, during the attaching operation of the polarizing film 30, in the winding operation of the release film by the winding roll, the attaching operation of the polarizing film 30 is finished, and the clamper 221c is attached to the release film 40. It may be performed at a predetermined timing after the clamp is released.

When the operations of Figs. 4A to 4C are completed, the operation shown in Fig. 5 is continued.

FIG. 5(a) shows a state in which the table 100 has risen from a descending (retracting) position to a vertical reference position h in the vertical direction. When the table 100 rises to the reference position h in the vertical direction, as shown in Fig. 5(a), the tip portion 30a of the polarizing film 30 is attached to the abutting end portion 10a of the glass substrate 10. It is reached. The raising operation of the table 100 is performed by the control device 300.

As described above, when the first aligning operation of the polarizing film 30 is performed, the control device 300 temporarily lowers the table 100 downward from the vertical reference position h by the table lifting control function (retreating). ) After controlling the lift mechanism so as to make it, the feeder 225 is controlled to perform the first alignment operation of the polarizing film 30 by the film member initial alignment control function. Then, the control device 300, by the table lifting control function, the lifting mechanism to raise the table 100 to the vertical reference position h at a predetermined timing until the attaching operation of the polarizing film 30 is started. To control. In addition, "predetermined timing until the attaching operation of the polarizing film 30 is started" means that the initializing operation of the polarizing film 30 is finished immediately after the initializing operation of the polarizing film 30 is finished, It is desirable to do it at almost the same timing.

By performing such control, the polarizing film 30 can be first matched with high precision, whereby the leading end 30a of the polarizing film 30 is attached to the starting end 10a of the glass substrate 10. Can be reached with high precision. That is, since the adhesive is applied to the polarizing film 30 from which the release film 40 is peeled off, when the table 100 is in the vertical position h at the vertical direction, when the first alignment operation of the polarizing film 30 is performed, the adhesive Is attached to the glass substrate 10, and the progress of the polarizing film 30 is hindered, so that the tip portion 30a of the polarizing film 30 is reached with high precision to the abutting end 10a of the glass substrate 10. There is a possibility that there may be a problem. In order to prevent such a problem, in performing the initial alignment operation of the polarizing film 30, the table 100 is temporarily lowered (retracted) in the downward direction from the vertical reference position h in the vertical direction.

As described above, when the first alignment operation of the polarizing film 30 is performed (see FIG. 4(c)), when the table 100 rises to the reference position h in the vertical direction (see FIG. 5(a)), press By the roll 240, the pressing roll 240 is moved (lowered) so that the tip portion 30a of the polarizing film 30 is pressed against the abutting end portion 10a of the glass substrate 10. As a result, the pressing roll 240 (the first pressing roll 241 and the second pressing roll 242) descends, so that the pressing point P of the first pressing roll 241 is at the front end portion of the polarizing film 30 ( 30a) is pressed against the starting end 10a of the glass substrate 10 (see FIG. 5(b) ). As a result, the polarizing film 30 is positioned at the starting end 10a of the glass substrate 10. Further, at this time, the second pressing roll 242 is in a state where the first pressing roll 241 is pressed.

The polarizing film is moved by moving the table 100 from the state shown in FIG. 5(b) (the state in which the tip portion 30a of the polarizing film 30 is pressed against the abutting end portion 10a of the glass substrate 10). The pasting operation of (30) is performed. That is, from the state of Fig. 5 (b), the table 100 moves along the x-axis in the direction of the arrow x'(left direction in the drawing), whereby the polarizing film 30 is attached to the starting end of the glass substrate 10 ( 10a) is used as a starting point (see Fig. 5(c)). At this time, since the pressing roll 240 maintains a state in which the polarizing film 30 is pressed, when the table 100 moves in the direction of the arrow x'(left direction in the city), the first pressing roll 241 is a clock While rotating in the direction, the second pressing roll 242 rotates counterclockwise to press the polarizing film 30 against the glass substrate 10.

When performing the affixing operation|movement of the polarizing film 30 as shown in FIG.5(b) from FIG.5(c), the affixing/peeling synchronization mechanism part 221 functions. That is, when performing the pasting operation of the polarizing film 30, the release film 40 is clamped at a predetermined position between the dancer roll 222 and the peeling section 210 as a tension imparting section, and the clamped position and peeling are performed. Between the portions 210, an operation of releasing the release film 40 from the polarizing film 30 (active peeling operation of the release film 40) is performed by actively synchronizing with the attaching operation of the polarizing film 30.

Specifically, as the table 100 moves along the x-axis in the direction of the arrow x'(left direction in the figure), the polarizing film (in this case, the polarizing film 30) attaches the starting end 10a of the glass substrate 10 It is attached as a starting point. As described above, when the table 100 moves along the x-axis in the direction of the arrow x'(left direction in the figure), the release film 40 is accompanied by the movement of the table 100 and the movement amount equal to the movement amount of the table 100. The peeling portion 210 advances in the folding direction, that is, in the release film advancing direction (arrow x direction).

As described above, when the affixing/peeling synchronization mechanism part 221 performs the operation of attaching the polarizing film 30 to the glass substrate 10 (the attaching operation of the polarizing film 30), the clamped position and the peeling part Between 210, the release film 40 is peeled off by actively synchronizing with the first polarizing film 30.

The operation of the sticking/peeling synchronous mechanism unit 221 will be further described. As described above, the affixing/peeling synchronous mechanism portion 221 includes a first folding roll 221a provided on the film member supply mechanism portion 200 side and a second folding roll 221b provided on the table 100 side. And a clamper 221c.

The clamper 221c clamps the release film 40 when performing the pasting operation of the polarizing film 30. For this reason, when the attaching operation of the polarizing film 30 is performed, when the release film 40 is clamped by the clamper 221c, when the table 100 moves in the direction of the arrow x'along the x axis, the film The position of the first folding roll 221a installed on the side of the member supply mechanism 200 does not change, and the second folding roll 221b installed on the table 100 side moves and the table 100 moves. Move together. Thereby, the release film 40 is pulled by the second folding roll 221b by the movement of the table 100, and advances in the release film advancing direction (arrow x direction).

In this way, when performing the attaching operation of the polarizing film 30, since the release film 40 is in a clamped state, the release film 40 is released from tension by the dancer roll 222 as a tension imparting part. In the released state, the tension applied to the release film 40 is only the tension between the clamper 221c and the peeling portion 210. In this state, the release film (in synchronization with the attaching operation of the polarizing film 30) Since the peeling operation of 40) is performed, the tension applied to the release film 40 becomes small.

For this reason, even with a configuration in which a large tension is applied to the release film by the dancer roll 222 as a tensioning part, the release film 40 is released from the tension by the dancer roll 222 and released. Too much tension is not applied to the film 40.

Thereby, according to the film member pasting apparatus 1 which concerns on embodiment, when performing the pasting operation|movement of the polarizing film 30, the tension applied to the release film 40 can be made small, whereby a release film When the 40 is rubbed by the folding portion 211 of the peeling portion 210, it is possible to suppress the release film 40 from being damaged. In addition, when the film member pasting device is used for a long time, there is also a problem that the folding part 211 of the peeling part 210 is also worn out by friction between the release films, but the film member pasting device 1 according to the embodiment has According to this, the wear of the folding portion 211 can also be suppressed.

In addition, when the folding portion 211 of the peeling portion 210 is an edge portion (in this case, a wedge shape), the peeling operation when the release film 40 is peeled from the polarizing film 30 (release film ( 40) can be reliably performed. In particular, when the folding portion 211 of the peeling portion 210 is, for example, a roll, the peeling operation of the release film 40 can be performed more reliably. That is, when the folding portion 211 is a roll, when peeling the release film 40 from the polarizing film 30, the polarizing film 30 is rolled into the roll together with the release film 40 to ensure the peeling operation. There may be a problem that it cannot be done. At this time, if the diameter of the roll is large, the occurrence of such a problem becomes more remarkable.

In the film member pasting device 1 according to the embodiment, in order to solve the above-described problem, the folding portion 211 of the peeling portion 210 is used as an edge portion. Thereby, the above-mentioned problem can be solved, and a reliable peeling operation becomes possible. However, when the folding portion 211 of the peeling portion 210 is an edge portion, there is a problem that the release film 40 is easily rubbed and the release film 40 is easily damaged, but the film member sticking according to the embodiment In the device 1, such a problem can be solved by providing the attaching/detaching synchronous mechanism section 221. In addition, the problem that the foldable portion 211 is liable to be worn out by rubbing the release film 40 at the foldable portion 211 of the peeling portion 210 can also be solved.

In addition, when performing the initial alignment of the polarizing film 30, the affixing/peeling synchronization mechanism unit 221 does not function, but when performing the initial alignment of the polarizing film 30, the initial alignment operation of the polarizing film 30 is performed. Since the release film 40 may be advanced as necessary to perform, the amount of progress of the release film 40 is not much. For this reason, the load exerted on the release film 40 can be made small, and there is little risk of breaking the release film or wearing the folding portion 211. In addition, when the first alignment of the polarizing film 30 is performed, the release film 40 is in a clamped state by the feeder 225, so in this case also the tension imparting portion applied to the release film 40 ( The tension by the dancer roll 222 has been released. This also makes it possible to reduce the load applied to the release film 40 when the first alignment of the polarizing film 30 is performed.

On the other hand, when the pasting operation of the polarizing film 30 is performed, the amount of progress of the release film 40 is also large, and the release film in a state where the tip portion 30a of the polarizing film 30 is pressed with the pressing roll 240 Because it peels off, the load applied to the release film 40 becomes large. In particular, when the size of the polarizing film 30 (size along the direction of travel) is large, the amount of progress of the release film 40 increases, and the load applied to the release film 40 becomes greater. In this case, the tension applied to the release film 40 can be suppressed to a small extent by providing the affixing/peeling synchronization mechanism part 221, and the load applied to the release film 40 can be reduced. Thereby, damage to the release film 40 can be suppressed. In addition, wear of the folding portion 211 can also be suppressed.

By the way, when the film member pasting operation as shown in Fig. 5(c) ends, the table 100 returns to the initial position, but when the table 100 returns to the initial position, by the clamper 221c The clamp of the release film 40 is released. Then, when the table 100 further moves in the direction of the arrow x'from the state shown in Fig. 5C, the table 100 moves to the position (the same position as the initial state) in Fig. 4A. Back. Thereby, the attaching process of the polarizing film 30 (1st polarizing film 30) with respect to the glass substrate 10 (1st glass substrate 10) is complete|finished, and a next glass substrate (2nd glass) is continued. The attaching process of the polarizing film (2nd polarizing film 30) with respect to the board|substrate 10 is performed.

In order to perform the attaching process of the second polarizing film 30 to the second glass substrate 10, the first glass substrate 10 in which the attaching process of the first polarizing film 30 is finished is performed from the table 100. Aside, the second glass substrate 10 is placed on the table 100, and the steps of FIGS. 4A to 4C and 5A to 5C are performed. . By repeating such a process, a polarizing film can be adhered sequentially to individual glass substrates.

As described above, according to the film member pasting device 1 according to the embodiment, when the pasting operation of the polarizing film 30 is performed, the pasting of the polarizing film 30 is performed by the pasting/peeling synchronization mechanism part 221. The release film 40 is peeled off by being actively synchronized with the action.

For this reason, when performing the pasting operation of the polarizing film 30, the tension applied to the release film 40 can be made small, whereby the release film 40 is the folding part 211 of the peeling part 210. ), it is possible to suppress the release film 40 from being damaged. In addition, wear of the folding portion 211 can also be suppressed. Moreover, since the folding part 211 of the peeling part 210 is an edge part, the peeling operation of the release film 40 can be performed reliably.

In addition, a guide member 230 for guiding the progress of the polarizing film 30 is provided on the front side of the peeling portion 210. Since the non-adhesive surface processing is performed on the guide surface 231 of the guide member 230, it is possible to prevent the polarizing film 30 adhesion surface from being attached to the guide surface 231 of the guide member 230. It is possible to smoothly advance the polarizing film 30 on the guide surface 231 of the guide member 230.

In addition, since the guide member 230 has the edge of the guide member tip 232 as an edge, the gap between the guide member tip 232 and the starting end 10a of the glass substrate 10 can be made as narrow as possible. In addition, the step between the tip end portion 232 of the guide member and the starting end portion 10a of the glass substrate 10 can be made as small as possible.

Thereby, the distance until the front end 30a of the polarizing film 30 reaches the abutting start end 10a of the glass substrate 10 can be shortened, so that the polarizing film 30 affix the starting end 10a In the meantime until it reaches ), it can be prevented from being bent by its own weight. Thereby, the tip part 30a of the polarizing film 30 advancing the guide surface 231 can be reached with high precision to the apex start end 10a of the glass substrate 10.

In addition, since the guide member 230 is provided so that the abutting end 10a of the glass substrate 10 is positioned on the extension of the guide surface 231, the guide surface 231 is also advanced by this. The leading end 30a of the polarizing film 30 can be reached with high precision to the starting end 10a of the glass substrate 10.

In addition, the guide member 230 is formed of a metal such as stainless steel, and the guide surface 231 of the guide member 230 is subjected to conductive and non-adhesive surface processing, and the guide surface ( 231) is electrically grounded (earth). For this reason, even when static electricity is charged in the polarizing film 30, static electricity charged in the polarizing film 30 can be removed. Speaking from this point of view, the guide member 230 can also be referred to as an electrostatic removal member. As described above, when the guide member 230 is an electrostatic removal member, dust or dust is hardly attached to the polarizing film 30, and the polarizing film 30 is affixed to the glass substrate 10 as a member to be joined. When performing the operation described above, the film member can be attached to the glass substrate 10 with high precision. In addition, when the glass substrate 10 to which the polarizing film 30 is attached is sent to the next process, static electricity can be prevented from being sent to the next process while being charged.

In addition, when the initial alignment operation of the polarizing film 30 is performed, the table 100 is temporarily retracted downward from the vertical reference position h in the vertical direction, and the initial alignment operation of the first polarizing film 30 is performed. The table 100 is returned to the reference position h in the vertical direction at a timing immediately after completion or at the same timing as when the first alignment operation of the first polarizing film 30 ends. Thereby, the polarizing film 30 can be first matched with high precision.

Further, the pressing roll 240 is made of a small diameter first pressing roll 241 positioned on the side in contact with the polarizing film 30 and a large diameter agent for backing up the pressing force of the first pressing roll 241. It is composed of two pressing rolls (242).

Since the pressing roll 240 has such a configuration, the first pressing roll 241 has a small diameter even if the gap between the tip end portion 232 of the guide member and the starting end 10a of the glass substrate 10 is narrow. Therefore, the polarizing film 30 can be pressed without contacting the guide member 230. In addition, since the second pressing roll 242 also serves to prevent bending of the first pressing roll 241, the polarizing film 30 is uniform across the entire width direction (direction along the rotation axis of the pressing roll 240). It can be reliably pressed with one pressing force.

In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. For example, modifications as shown below are also possible.

(1) In the above embodiment, the case where the diameter of the first pressing roll is set to about 10 mm is illustrated, but the diameter of the first pressing roll does not necessarily have to be about 10 mm, and the guide member tip portion 232 and the glass substrate It can be made into the optimum diameter according to the distance d of the starting end 10a of (10), etc.

(2) In the above-described embodiment, the case where the guide member 230 adopts a triangular block shape is illustrated, but the shape of the guide member 230 is not limited, and the release film 40 is peeled off. The front end portion 30a of the polarizing film 30 can be made to advance toward the abutment start end 10a of the glass substrate 10 mounted on the table 100, and may be, for example, a plate shape.

FIG. 6 is a view for explaining the case where the guide member 230 is plate-shaped. In addition, FIG. 6 corresponds to FIG. 3 (a), and only the point in which the guide member 230 is plate-shaped is different, and since the other components are the same as in FIG. 3, the same components are given the same reference numerals. have. Even when the guide member 230 is plate-shaped, it is preferable that the guide member tip portion 232 has an edge as shown in FIG. 6.

By doing in this way, the front-end|tip part 30a of the polarizing film 30 can be reached to the affixing start-end|tip 10a of the glass substrate 10 with high precision. Further, even when the guide member 230 is plate-shaped, the guide surface 231 of the plate-shaped guide member 230 is subjected to a non-adhesive surface treatment having conductivity, and the guide surface 231 is electrically Is grounded. Thereby, the static electricity countermeasure similar to the guide member 230 used in the film member pasting apparatus 1 which concerns on embodiment is attained. In addition, the guide member 230 is not a plate shape having a thickness as shown in FIG. 6, but a plate member having a plate thickness of, for example, about 1 mm to several mm may be used. The member tip portion 232 automatically becomes an edge.

(3) In the above-described embodiment, when the attaching operation of the polarizing film 30 shown in Fig. 4 is performed, the film member supply mechanism 200 is fixed and the table 100 is reciprocated along the x axis. Although illustrated, the table 100 may be fixed and the film member supply mechanism 200 may be reciprocated.

Specifically, the position of the table 100 is fixed in the state in which the glass substrate 10 is loaded on the table 100 as in the initial state of Fig. 4A. Then, the film member supply mechanism portion 200 is moved in the direction of the arrow x'in FIG. 4 (left direction in the drawing), and is brought into substantially the same state as in FIG. Steps 5(a) to 5(c) are performed. In this case, when affixing operation of the polarizing film 30 is performed, the table 100 is fixed and the film member supply mechanism 200 is moved in the direction of the arrow x. Even by performing such an operation, the polarizing film 30 can be affixed to the glass substrate 10 as in the above-described embodiment.

In addition, the attaching operation of the polarizing film 30 may use together the operation of reciprocating the table 100 along the x-axis, and the operation of reciprocating the film member supply mechanism part 200 along the x-axis. Even by performing such an operation, the polarizing film 30 can be affixed to the glass substrate 10 as in the above-described embodiment. In this case, the effect that the sticking operation can be made faster can also be obtained.

In addition, even when the table 100 is fixed and the film member supply mechanism portion 200 is reciprocated, the affixing/peeling synchronization mechanism portion 221 can function when performing the affixing operation of the polarizing film 30. have. In this case, when performing the attaching operation of the polarizing film 30, the film member supply mechanism part 200 moves in the arrow x direction, and at this time, the first folding roll 221a also moves the film member supply mechanism part 200 While moving together, the position of the second folding roll 221b provided on the table 100 side does not change.

For this reason, the release film 40 is pulled by the 1st folding roll 221a with the movement of the film member supply mechanism part 200, and as the release film 40 peels from the polarizing film 30, the polarizing film ( 30) This goes on. Even in this case, since the release film 40 is clamped by the clamper 221 cc, the release film 40 is peeled off by actively synchronizing with the attaching operation of the polarizing film 30. When peeling the release film 40 from the film 30, the tension (tension) applied to the release film can be reduced.

In addition, even when the operation of reciprocating the table 100 along the x-axis and the operation of reciprocating the film member supply mechanism 200 along the x-axis are used together, the affix/peel synchronization mechanism can function.

(4) As another example of the control of the feeder 225 by the control device 300, the position of the rear end 30b of the polarizing film 30 is monitored, and the rear end 30b of the polarizing film 30 is monitored. The position may be controlled to advance the release film 40 in the release film advance direction until the position of the rear end portion 30b of the polarizing film 30 moves by the target movement amount (referred to as the target movement amount). Thereby, the front-end|tip part 30a of the polarizing film 30 can be reached to the pressing point P of the 1st press roll 241 with high precision. This control aims at how much the rear end 30b of the polarizing film 30 moves from a predetermined position, so that the leading end 30a of the polarizing film 30 reaches the pressing point P of the first pressing roll 241. It can be implemented by obtaining in advance as a moving amount.

(5) In the above-described embodiment, the case where the edge portion of the distal end folding portion is wedge-shaped (acute) is exemplified, but is not limited to being wedge-shaped (acute), and may be, for example, a substantially right-angled edge portion.

(6) In the above-described embodiment, when performing the initial alignment operation of the polarizing film 30, the operation of lowering (retreating) the table 100 is moved to the position shown in FIG. 4(b). Although the (100) is retracted, the table 100 may be moved to the position shown in FIG. 4B in a state where the table 100 is lowered (retracted) in the initial state of FIG. 4A.

(7) In the above-mentioned embodiment, a polarizing film is used for the glass substrate used for one of two glass substrates used for a liquid crystal panel (glass substrate provided on the front side of the liquid crystal layer and glass substrate provided on the back side) Although the case of attaching has been described, it can be carried out almost as well when attaching the polarizing film to the glass substrate used for the other side.

(8) In the said embodiment, it is assumed that the film member is a polarizing film used for a liquid crystal panel, and the to-be-attached member is a glass substrate used for a liquid crystal panel, and the film member for attaching a polarizing film to the said glass substrate. Although the sticking device has been described, the film member sticking device is not limited to the film member sticking device described in the above embodiment, and can be widely applied to a device for sticking a film member to a sticking member.

(9) In the above-described embodiment, the film member is a long rectangle, but the shape of the film member is not limited to a long rectangle, and may be a square, and is not limited to a rectangle and a square (rectangular).

(10) In the above-described embodiment, the first pressing roll 241 and the second pressing roll 242 have a smaller diameter than the first pressing roll 241 compared to the second pressing roll 242. If the pressing roll 242 can function as a backup roll, the first pressing roll 241 and the second pressing roll 242 may have the same diameter.

(11) In the above-described embodiment, the pressing roll 240 exemplifies a case where two pressing rolls are stacked in two stages, but is not limited to two, and has a configuration in which three or more pressing rolls are stacked. You may do it.

(12) In the above embodiment, the guide surface 231 of the guide member 230 is electrically grounded (earthed) through the guide member 230, a support member (not shown), and the stage 50, The lead wire for ground (earth) may be connected to the guide surface 231 or the guide member 230 to directly ground (earth) the guide member.

(13) In the above embodiment, the film member is a polarizing film used for a liquid crystal panel, but the present invention is not limited to this. For example, the film member may be a protective film used for a liquid crystal panel, or an electromagnetic wave shield film used for an electronic device. In addition, in the said embodiment, although the to-be-attached member was made into the glass substrate used for a liquid crystal panel, this invention is not limited to this. For example, a synthetic resin substrate (including a synthetic resin film) used in a liquid crystal panel may also be used. Further, a glass substrate or a synthetic resin substrate (including a synthetic resin film) used for a liquid crystal panel (for example, an organic EL panel or other display) may also be used. Moreover, an electronic circuit board used for other than a display (for example, an electronic device) may be used.

(14) In the above-described embodiment, as a process for performing non-adhesive surface processing having conductivity on the guide surface 231 of the guide member 230, a surface called "Tosical (registered trademark) S coating processing" Adopting the technology of processing, such coating processing, Tosical (registered trademark) S, UNA-300 series (UNA-310-X10), UNA-800 series, TS-1000 series, TS-1080 series, TS Although the -1310 series can be suitably used, the present invention is not limited thereto. In addition, although the film thickness of the coating film of Tosical (registered trademark) S is, for example, 1 μm to 200 μm, preferably 3 μm to 150 μm, can be suitably used, but the present invention is not limited to this. no. Further, before forming the coated film of Toshika (registered trademark) S, an uneven structure may be formed on the guide surface 231 of the guide member 230. As the average surface roughness of the concavo-convex structure in this case, 2 to 15 µm can be suitably used, but the present invention is not limited to this.

(15) In the above-mentioned embodiment, when the peeling/release peeling mechanism part 221 actively synchronizes with the sticking operation of the polarizing film 30 to perform the peeling operation of the release film, the sticking/peeling sync mechanism part 221 A clamper 221c was provided on the clamping film, and the release film 40 was clamped by the clamper 221c. However, the clamper 226 of the feeder 225 was polarized film without providing the clamper 221c. It is also possible to use not only for the initial-fit operation of (30), but also for affixing/peeling synchronous operation in the affixing/peeling synchronization mechanism part 221. In this case, when performing the sticking/peeling synchronous operation, the release film 40 is clamped by the clamper 226 of the feeder 225. Even in this way, the release film 40 is released from the tension by the dancer roll 222 as a tension imparting portion, and the tension applied to the release film 40 can be reduced.
