Description

Film member sticking device and method

The invention relates to a film member sticking device.

In the past, a variety of film member sticking devices have been proposed. One of the film member sticking devices is to peel off the release film from the film member to which the peelable release film is pasted, and then stick the film member that has peeled off the release film On the adhered member (for example, refer to Patent Document 1).

FIG. 9 is a schematic view of the main parts of the film member sticking device described in Patent Document 1. In addition, the “plastic film bonding apparatus” in Patent Document 1 will be described as a “film member bonding apparatus” in this specification.

As shown in FIG. 9, the film member sticking device described in Patent Document 1 includes a peeling unit 830 that peels off the release film 810 from the film member 820 to which the peelable release film 810 is stuck. The peeling unit 830 is provided with a peeling portion 840, and a tip portion of the peeling portion 840 is formed with a folded portion 841 at an acute angle. After the release film 810 is folded back at the peeling portion 840, the traveling direction is changed by the roller 850 and travels in the arrow x'direction.

When the peeling unit 830 peels the release film 810 from the thin film member 820, the peeling unit 830 faces the arrow x with the suction device (not shown) sucking the thin film member 820 on the upper end surface of the peeling unit 830. Swipe in the direction. With this, the release film 810 can be peeled from the thin film member 820.

On the other hand, the film member 820 sucked by the suction device is transferred back to a predetermined sticking position of the sticking member (not shown) and is stuck on the sticking position.

[Patent Document 1] JP 2011-251805

In the thin film member bonding apparatus described in Patent Document 1, although the release film 810 can be peeled off from the thin film member 820 to which the peelable release film 810 is stuck, the thin film member 820 from which the release film 810 has been peeled off It sticks to the member to be stuck, but there still remains a problem that the peeling portion 840 for peeling the release film 810 from the film member 820 should be improved.

That is, in the peeling portion 840 used in the film member bonding apparatus described in Patent Document 1, the folded portion 841 is at an acute angle, and the release film 810 is folded at the acute-angled folded portion 841. Therefore, depending on the material of the release film 810, the release film 810 may be damaged or adhered due to friction, and eventually the release film may be damaged. Not only that, once the thin-film member sticking device is used for a long time, the folded portion 841 may be worn due to friction with the release film.

Once the release film 810 is damaged or the turn-back portion 841 is worn, it will adversely affect the running operation of the film member and the peeling operation of the release film.

In addition, the same problem exists in other film member bonding apparatuses having a peeling portion 840 similar to the film member bonding apparatus described in Patent Document 1.

Fig. 10 is an explanatory diagram for explaining an example of another conventional film member sticking device. Hereinafter, the film member bonding apparatus described in Patent Document 1 is referred to as a “conventional first film member bonding apparatus”, and the film member bonding apparatus shown in FIG. 10 is referred to as a “conventional second film member bonding apparatus”. In addition, in FIG. 10, the peeling part used for the conventional 2nd film member sticking apparatus is shown simplified.

As shown in FIG. 10, the conventional second film member sticking device also includes a peeling portion 930 that peels off the release film 910 from the film member 920 to which the peelable release film 910 is pasted. The turn-back portion 931 on the peeling portion 930 has an acute-angle shape. After the release film 910 is turned back at the turn-back portion 931, the release film 910 travels in the direction of arrow x, so that the peelable release film is adhered On the thin film member 920 of 910, the release film 910 is peeled off.

However, in the conventional second film member sticking device, when the release film 910 is peeled off, the film member 920 is not sucked by the suction device, but the film member 920 is slightly moved while peeling off the release film 910. After the front end portion 920a (sometimes simply referred to as the front end portion 920a) of the film member 920 in the traveling direction reaches the bonding start end 940a of the adhered member 940, the front end portion 920a of the film member 920 is pressed by the pressing roller 950 or the like While moving the table 960 along the guide rail 970 in the direction of the arrow x', the release film folded back at the turning portion 931 is stretched in the direction of the arrow x. Thereby, the film member 920 can be pasted on the pasted member 940.

In the conventional second film member sticking device, since the release film 910 is also folded back by the folded portion 931 at an acute angle, it is the same as the conventional first film member sticking device shown in FIG. In addition to the damage of the release film 910, the folding member 931 is worn due to the friction between the film member sticking device and the release film 910 due to long-term use of the film member affixing device, and finally the running operation of the film member 920 and the release film 910 The peeling operation caused adverse effects.

In order to eliminate the above-mentioned problems, it may be considered not to set the turned-back portion at an acute angle, but to set the turned-back portion 931 as a turned-back portion 931a with a circular arc shape as shown in the dotted frame B in FIG. 10. However, in the conventional second film member pasting device, the positional relationship between the folded-back portion and the pasting start end 940a of the pasted member 940 is also an extremely important factor.

The reason for this is that, in the conventional second film member sticking device, when the front end portion 920a of the film member 920 after peeling off the release film 910 through the turn-back portion 931 reaches the adhered member, the accuracy of the arrival position There are very high demands.

That is, in the conventional second film member sticking device, the following operation is performed: The film member 920 after the release film 910 is peeled off through the turn-back portion 931 on the peeling portion 930 will be on the extension line of the inclined surface 932 of the peeling portion 930 After the front end 920a of the film member 920 reaches the starting end 940a of the pasting member 940, the front end 920a of the film member 920 is pressed by the pressing roller 950 or the like, and the table 960 is pressed. While moving in the direction of the arrow x'along the guide rail 970, the release film folded back at the turning portion 931 is stretched in the direction of the arrow x.

Therefore, when the front end portion 920a of the film member 920 reaches the adhered member 940, if the accuracy of reaching the position is low, the film member 920 cannot be accurately adhered to the correct position of the adhered member 940. Specifically, for example, as shown in the dashed frame B in FIG. 10, once the turn-back portion 931 is provided as a turn-back portion 931a with an arc, the film member 920 after the release film is peeled off through the turn-back portion 931a When the extension line of the inclined surface 932 of the peeling portion 930 travels, the distance from the front end portion 920a of the film member 920 to the pasting start end 940a of the pasted member 940 becomes longer, and the time from reaching the pasting start end 940a Inside, it may bend due to its own weight. Therefore, the front end portion 920a of the film member 920 cannot reach the pasting start end 940a of the pasted member 940 with high accuracy, and thus the film member 920 cannot be accurately pasted on the pasted member 940.

The above problem is that the front end portion 920a of the film member 920 cannot reach the pasting start end 940a of the pasted member 940 with high accuracy, resulting in the problem that the film member 920 cannot be accurately pasted on the pasted member 940, not only This may occur when the turn-back portion 931 is provided as a turn-back portion 931a with an arc, and may also occur when the turn-back portion 931 is provided as a roller (shown), for example. That is, even if the folded-back portion 931 is provided as a roller, the film member 920 after peeling off the release film 910 is inclined at the peeling portion 930 in the same manner as when the folded-back portion 931 is provided as the folded-back portion 931a with an arc. When the extension line of the surface 932 travels, the distance to the pasting start end 940a of the pasted member 940 becomes longer, so that the front end portion 920a of the film member 920 cannot reach the pasting start end 940a of the pasted member 940 with high accuracy .

In view of the above problems, the object of the present invention is to provide a film member sticking device that allows the front end portion of the film member from which the release film is peeled to travel to reach the sticking starting end of the sticked member, using the sticking starting end as a starting point The film member is adhered to the film adhesion surface, which can prevent the release film from being damaged or the folded portion from being worn, so that the film member can be reliably moved and the release film can be peeled off.

[Embodiment 1]

FIG. 1 is a diagram for explaining the film member sticking device 1 according to the first embodiment. The film member sticking device 1 according to the first embodiment shown in FIG. 1 is a schematic diagram, and therefore does not necessarily reflect the actual size. As shown in FIG. 1, the film member bonding apparatus 1 according to the first embodiment includes: a table 20 for placing a glass substrate 10 as a member to be bonded; a film member supply mechanism section 100, and a polarizing film 30 as a film member (Refer to FIG. 2), while the release film 40 is peeled off, the polarizing film 30 is advanced, and the polarizing film 30 is supplied so that the front end portion 30a of the polarizing film 30 in the proceeding direction reaches the adhesion starting end 10a of the glass substrate 10; and The control device 200 has a control function for controlling each component of the film member sticking device 1 according to the first embodiment. The control function of the control device 200 will be described later.

In the film member sticking apparatus 1 according to the first embodiment, the film member supply mechanism 100 is fixed and the table 20 is moved (moved along the x-axis) to stick the polarizing film 30 on the glass substrate 10 To explain. FIG. 1 shows a state where the table 20 has moved to a position where the polarizing film 30 is adhered to the glass substrate 10.

The film member supply mechanism section 100 has a peeling roller 110 that peels the release film 40 from the polarizing film 30 by folding back the release film 40 in a direction almost opposite to the traveling direction of the polarizing film 30; The mechanism portion 120 advances the release film 40 folded back by the peeling roller 110; the guide member 130 has a guide surface 131 during the movement of the polarizing film 30 after the peeling film 110 peels off the release film 40 The guide roller 140 presses the front end portion 30a of the polarizing film 30 against the pasting end 30a (hereinafter referred to as the front end portion 30a) of the polarizing film 30 in the advancing direction of the polarizing film 30 when it reaches the pasting starting end 10a of the glass substrate 10 At the starting end 10a; and the camera 150, it is possible to photograph a predetermined portion (described later) of the polarizing film 30.

As the peeling roller 110, a roller having bearings is used. Thereby, when the release film 40 is peeled off from the polarizing film 30, the release film 40 can be peeled off smoothly with a small force.

The film member supply mechanism section 100 is provided with rollers 161 and 162 for traveling after bending the polarizing film 30 (the polarizing film 30 in a state where the release film 40 is adhered) in addition to the above-described structural requirements. In addition, there are a conveying mechanism part for conveying the polarizing film 30, a tension adjusting roller arranged on the way, and the like, but these constituent elements are not shown in the figure.

In FIG. 1, after the polarizing film 30 (the polarizing film 30 in the state where the release film 40 is attached) is bent downward through the roller 161 at a large angle, the roller 162 and the xy plane form a predetermined angle (in the implementation In the film member sticking apparatus 1 according to the first embodiment, it is bent at 30 degrees) and reaches the peeling roller 110 after being bent. Although the polarizing film 30 (the polarizing film 30 in the state where the release film 40 is attached) is curved in the downward direction or oblique direction by the rollers 161 and 162 on the traveling path, the polarizing film 30 is generally along the The x-axis follows the right-to-left direction (arrow x'direction) shown in the figure. Therefore, in this specification, when describing the traveling direction of the polarizing film 30, "the direction of the arrow x'along the x-axis" or "the right to left direction of the illustration" is used for description.

FIG. 2 is a diagram for explaining the polarizing film 30. Among them, FIG. 2(a) is a plan view of the polarizing film 30, and FIG. 2(b) is a cross-sectional view of the polarizing film 30. As shown in FIG. 2, the polarizing film 30 is in the form of an elongated sheet, and the elongated sheet-shaped release film 40 is adhered to the polarizing film body 32 via an adhesive layer 34 in a peelable state. The polarizing film 30 is provided with cutouts at fixed lengths with the release film 40 remaining. With the cutouts, the polarizing film 30 can be made into small pieces so that it can be attached to each glass to be adhered. The size of the substrate 10 (refer to FIG. 1) corresponds. For example, when the long side (length 1500mm) of the glass substrate 10 is placed on the table 20 along the x-axis, the long side (length is 1490mm) Cuts C1, C2, ... are provided.

In addition, in the long sheet-shaped polarizing film 30 shown in FIG. 2, when each polarizing film corresponding to each glass substrate 10 is described separately, starting from the left in FIG. 2, the first polarizing film The order of 30A, the second polarizing film 30B, ... will be described. The notches C1, C2,... May represent the rear end portion 30b (hereinafter simply referred to as the rear end portion) of each polarizing film 30 in the traveling direction, or may represent the front end portion 30a. For example, for the first polarizing film 30A, the cutout C1 represents the rear end portion 30b of the first polarizing film 30A, and for the second polarizing film 30B, the cutout C1 represents the front end portion 30a of the second polarizing film 30B.

Next, returning to FIG. 1, each constituent element of the film member bonding apparatus 1 according to the first embodiment will be described in further detail.

The table 20 can reciprocate along the x-axis in the direction of the arrow x-x' on the guide rail 60 laid on the platform 50. In addition to reciprocating along the x axis, the table 20 can also perform position adjustment along the y axis and angle adjustment on the xy plane. In addition, the reciprocating movement of the table 20 along the x axis, the position adjustment along the y axis, and the angle adjustment on the xy plane can be controlled by a control function of the control device 200. The table 20, the platform 50, and the guide rail 60 are made of metal such as iron, for example.

The release film traveling mechanism unit 120 has a function of allowing the release film 40 folded back by the peeling roller 110 to travel in the arrow x direction. In addition, the traveling direction of the release film 40 (arrow x direction) after being folded back by the peeling roller 110 is referred to as a “release film traveling direction”.

The release film traveling mechanism unit 120 includes: a tension adjustment roller 125 provided on the downstream side in the traveling direction of the release film 40 folded back by the peeling roller 110; a plurality of rollers (for example, rollers 121 to 124); and a peeling roller 110 The feeding mechanism portion 126 between the tension adjusting roller 125 (specifically between the roller 122 and the roller 123); and the winding which is provided on the downstream side of the tension adjusting roller 125 and used for winding the release film 40 Roller (not shown), etc.

The feed mechanism portion 126 has a plurality of clamps 127 for holding the release film 40, and can reciprocate in the direction of the arrow x-x' along the x axis. The feed mechanism portion 126 has a function for causing the front end portion 30a of the polarizing film 30 from which the release film 40 has been peeled to reach the adhesion starting end 10a of the glass substrate 10.

The operation of the feed mechanism unit 126 is performed by a control function of the control device 200. In this case, the control device 200 monitors the position (position along the x-axis) of a predetermined portion (for example, the rear end portion 30b) of the polarizing film 30 based on the shooting data of the camera 150, and controls the feeding mechanism portion 126 so that the polarizing film 30 The front end portion 30a reaches the sticking starting end 10a of the glass substrate 10.

As an example of controlling the feeding mechanism unit 126 by the control device 200, for example, the control device 200 monitors the rear end portion of the polarizing film (first polarizing film 30A) to be adhered at this time based on the shooting data from the camera 150 30b (the cut C1 between the first polarizing film 30A and the second polarizing film 30B), and the feed mechanism portion 126 is operated until the position of the rear end portion 30b (cut C1) reaches the target position.

Specifically, the position of the rear end portion 30b of the polarizing film 30 when the front end portion 30a of the polarizing film 30 reaches the sticking starting end 10a of the glass substrate 10 correctly is taken as the "target position", and the control device 200 separates the position The mold film 40 travels in the direction in which the release film travels until the position of the rear end portion 30b of the polarizing film to be adhered reaches the target position. Thereby, the front end portion 30a of the first polarizing film 30A can accurately reach the sticking starting end 10a of the glass substrate 10.

Once the position of the rear end portion 30b (notch C1) of the polarizing film 30 reaches the target position, the clamping of the release film 40 is released, and the feed mechanism portion 126 is controlled to return to the original position.

In the film member bonding apparatus 1 according to the first embodiment, the camera 150 monitors the position of the rear end portion 30b (notch C1) of the first polarizing film 30A to be bonded. The reason for this arrangement is that if the If the front end portion 30a of the first polarizing film 30A to be pasted is monitored, the presence of members such as the pressing roller 140 (see FIG. 1) makes it difficult to secure the space required for installing the camera 150 . However, if sufficient space is required for installing the camera 150, the front end portion 30a of the first polarizing film 30A used as the object to be adhered at the present stage may be provided for monitoring.

Next, the guide member 130 and the pressing roller 140 will be described with reference to FIG. 3.

FIG. 3 is a diagram for explaining the guide member 130 and the pressing roller 140. Among them, FIG. 3(a) is an enlarged view of the pressing roller 140 in FIG. 1 and the range surrounded by the dotted frame A in FIG. 1, and FIG. 3(b) is viewed from above along the z-axis in FIG. 3 ( a) Plan view. In FIG. 3(b), the illustration of the pressing roller 140 in FIG. 3(a) is omitted.

First, the guide member 130 will be described. The guide member 130 is a member for guiding the polarizing film 30 from which the release film 40 has been peeled off. Since FIG. 3 is a schematic view similar to FIG. 1, the mounting structure of the guide member 130 is omitted. The guide member 130 is mounted on a support member (not shown) that is erected on the platform 5. The support member is made of metal such as stainless steel, and the guide surface 131 (the surface on the side in contact with the polarizing film 30) of the guide member 130 is subjected to non-adhesive surface processing for preventing adhesion of the adhesive. The purpose of this is that one surface of the polarizing film 30 is an adhesive surface having adhesiveness.

That is, since the peelable release film 40 is adhered to the adhesive surface of the polarizing film 30, one surface of the polarizing film 30 (the surface to which the release film 40 is adhered) from which the release film 40 is peeled off has Since the adhesive is not applied to the guide surface 131 of the guide member 130 to prevent the adhesive from adhering to the surface, the adhesive surface of the polarizing film 30 will adhere to the guide surface 131 of the guide member 130, resulting in polarized light The film 30 cannot smoothly travel along the guide surface 131 of the guide member 130.

Non-adhesive surface processing for preventing adhesion of adhesives is a publicly known technology, and for example, a surface processing technology called "TOSICAL (registered trademark) S COATING" can be used. By applying such surface processing (TOSICAL (registered trademark) S COATING film formation processing/TOSICO Co., Ltd.) to the guide surface 131 of the guide member 130, it is possible to prevent the adhesion surface of the polarizing film 30 from which the release film 40 is peeled off. When it adheres to the guide surface 131 of the guide member 130, the polarizing film 30 is smoothly advanced to the adhesion starting end 10a of the glass substrate 10. For TOSICAL (registered trademark) S, for example, suitable for use: UNA-300 series (UNA-310-X10), UNA-800 series, TS-1000 series, TS-1080 series and TS-1310 series products.

The thickness of the TOSICAL (registered trademark) S COATING coating is, for example, 1 μm to 200 μm, preferably 3 μm to 150 μm. Before the TOSICAL (registered trademark) S COATING film is formed, an uneven structure may be formed on the guide surface 131 of the guide member 130 in advance. In this case, the average surface roughness Ra of the uneven structure is preferably set in the range of 2 μm to 15 μm.

The guide member 130 is provided such that the guide surface 131 is inclined at an acute angle with respect to the glass substrate 10 while using the front end portion of the guide member 130 as an edge. Specifically, in the film member sticking device 1 according to the first embodiment, the guide member 130 has a triangular block shape, and the front end portion 132 has an acute angle.

As shown in FIG. 3( a ), the guide member 130 having such a structure is provided so as to reach a position on the vertical line L (referred to as the When the bonding operation starts), the bonding start end 10a of the glass substrate 10 is positioned on the extension line of the guide surface 131. In addition, the guide member 130 is also provided so as not to be in contact with the glass substrate 10 placed on the table 20 (position along the z-axis), and to reduce the drop between the front end portion 132 and the glass substrate 10 Height. In addition, the “pressing point P” of the pressing roller 140 refers to a point where the pressing roller 140 applies a pressing force to the polarizing film 30 when the pressing operation of the polarizing film 30 is performed.

In the film member bonding apparatus 1 according to the first embodiment, the inclination of the guide surface 131, that is, the angle θ between the guide surface 131 and the xy plane (between the guide surface 131 and the glass substrate 10 placed on the table 20 The angle θ) is set to 30 degrees. In addition, it is not necessary to set the angle θ between the guide surface 131 and the glass substrate 10 to a very strict 30 degrees, as long as the front end portion 30a of the polarizing film 30 can smoothly reach the bonding start end 10a of the glass substrate 10.

In addition, the guide member 130 is preferably set such that when the pasting start end 10a of the glass substrate 10 reaches the pasting start position, the distance between the front end portion 132 of the guide member 130 and the pasting start end 10a of the glass substrate 10 is as short as possible Interval (interval along the x axis) d. The interval d differs depending on the inclination angle of the guide surface 131. In the film member bonding apparatus 1 according to the first embodiment, the interval d is 15 mm.

The guide member 130 is electrically grounded. Specifically, as described above, the guide member 130 is mounted on the support members (not shown) that are vertically provided on the platform 50. These support members and the platform 50 are both made of metal, so the guide surface 131 passes through these support members And after the platform 50 is electrically grounded. Although the guide surface 131 of the guide member 130 is applied with non-adhesive surface processing as described above, such surface processing does not impair the conductivity of the guide surface 131.

Since FIG. 1 is a schematic diagram showing the film member sticking device 1 according to the first embodiment, the specific installation state of the platform 50 is not shown. The platform 50 is a platform installed in a state of being electrically grounded to the ground of the factory. With this, the guide member 130 together with its guide surface 131 is electrically grounded after passing through the support member and the platform 50.

As described above, since the front end portion 132 of the guide member 130 is an edge, the distance between the front end portion 132 of the guide member 130 and the bonding start end 10a of the glass substrate 10 can be shortened as much as possible The drop between the front end portion 132 of the guide member 130 and the sticking start end 10a of the glass substrate 10. In this way, it is possible to shorten the adhesion of the front end portion 30a of the polarizing film 30 to the glass substrate 10 as compared with providing the folded-back portion with, for example, an arc-shaped folded-back portion (refer to the dotted circle B in FIG. 10). The distance to the starting end 10a prevents the polarizing film 30 from bending due to its own weight before reaching the starting end 10a. Thereby, the front end portion 30a of the polarizing film 30 traveling on the guide surface 131 can be accurately reached to the sticking starting end 10a of the glass substrate 10. In addition, since the guide member 130 is provided such that the sticking start end 10a of the glass substrate 10 is located on the extension line of the guide surface 131, the front end portion 30a of the polarizing film 30 traveling on the guide surface 131 can also be made by such an arrangement It reaches the sticking starting end 10a of the glass substrate 10 accurately.

In addition, by electrically grounding the guide member 130, even if the polarizing film 30 as a thin film member is charged with static electricity, the static electricity can be removed. By removing the static electricity on the polarizing film 30, it is not only difficult for dust or trash to adhere to the polarizing film 30, but also the polarizing film 30 can be adhered to the glass substrate 10 with high accuracy when the polarizing film 30 is adhered to the glass substrate 10 On the glass substrate 10. In addition, when the glass substrate 10 to which the polarizing film 30 is adhered is transported to the next step, the polarizing film 30 can also be prevented from being transported to the next step with static electricity.

Next, the pressing roller 140 will be described. As shown in FIG. 3(a), the pressing roller 140 is a structure in which two rollers 141 and 142 with different diameters are superimposed along two lines along the vertical line L, and their respective rotation axes 141a and 142a are along the direction of the front end portion 30a of the polarizing film 30 (In the direction of the y-axis) setting. The respective rotation shafts 141a and 142a of the two pressing rollers 141 and 142 are rotatably mounted on the pressing roller mounting member 143, respectively. The pressing roller mounting member 143 is mounted on the film member supply mechanism part 100.

Here, of the two pressing rollers 141 and 142, the pressing roller 141 on the side in contact with the polarizing film 30 is set as the first pressing roller 141, and the other pressing roller 142 is set as the second pressing roller 142. In this case The diameter Φ1 of the first pressing roller 141 (see (a) of FIG. 3) is set to be smaller than the diameter Φ2 of the second pressing roller 142. In the film member bonding apparatus 1 according to the first embodiment, the diameter Φ1 of the first pressing roller 141 is approximately 10 mm. The configuration in which the first pressing roller 141 and the second pressing roller 142 are arranged in two stages and the reason for setting the diameter Φ1 of the first pressing roller 141 to be smaller than the diameter Φ2 of the second pressing roller 142 will be described later.

The pressing roller 140 (the first pressing roller 141 and the second pressing roller 142) having the above-described configuration can move up and down along the z-axis direction (arrow z-z' direction) along with the pressing roller mounting member 143. When the film according to the first embodiment When the component pasting device 1 does not perform the pasting operation (abbreviated as non-pasting operation), the pressing roller 140 will be separated from the plane (xy plane) included in the glass substrate 10 placed on the table 20 (located above it), and when When the film member bonding apparatus 1 according to the first embodiment performs the bonding operation (abbreviated as the bonding operation), the pressing roller 140 is lowered to press the polarizing film 30. The raising and lowering operations of the pressing roller 140 are performed by a control function of the control device 200.

In addition, the reason that the diameter Φ1 of the first pressing roller 141 is set to be smaller than the diameter Φ2 of the second pressing roller 142, and the reason for superimposing the second pressing roller 142 with a larger diameter on the first pressing roller 141 is as follows.

That is, after the glass substrate 10 reaches the pasting operation start position, since the distance d between the front end portion 132 of the guide member 130 and the pasting starting end 10a of the glass substrate 10 is 15 mm as described above, the polarizing film is pressed by the first pressing roller 141 In the state of 30, in order to prevent the first pressing roller 141 from coming into contact with the guide member 130, it is necessary to set the diameter Φ1 of the first pressing roller 141 as small as possible. On the other hand, once the diameter of the first pressing roller 141 is set to be small, it will occur that the first pressing roller 141 cannot be applied to the entire width direction of the polarizing film 30 (the width along the y-axis direction). The problem of even pressing force.

Specifically, the length of the polarizing film 30 in the width direction (in the y-axis direction in FIG. 3) in FIG. 3 is approximately 890 mm. On the other hand, if the length of the polarizing film 30 in the width direction (in the y-axis direction in FIG. 3) is greater than 890 mm, the length of the first pressing roller 141 along the rotation axis 141a (length along the y-axis) will also become longer. At this time, the diameter Φ1 of the first pressing roller 141 becomes very small with respect to the length of the first pressing roller 141 along the rotating shaft 141a, thereby easily causing the first pressing roller 141 to bend, and once the first pressing roller 141 generates Bending, it is impossible to apply a uniform pressing force across the entire width. Therefore, while setting the diameter Φ1 of the first pressing roller 141 as small as possible, the second pressing roller 142 having a larger diameter is also superposed on the first pressing roller 141 so that the pressing force at the pressing point P It is evenly distributed in the entire width direction of the polarizing film 30.

By providing the pressing roller 140 with the above-described structure, even when the distance d between the front end portion 132 of the guide member 130 and the bonding start end 10a of the glass substrate 10 is only 15 mm, the first pressing roller 141 can The polarizing film 30 is reliably pressed under the stage without being in contact with the guide member 130. In addition, the second pressing roller 142 can also prevent the first pressing roller 141 from bending, thereby helping the first pressing roller 141 press the entire width direction of the polarizing film 30 with a uniform pressing force. In this way, the second pressing roller 142 functions as an auxiliary roller that assists the first pressing roller 141 to press.

Next, the operation of the film member bonding apparatus 1 according to the first embodiment (in particular, the bonding operation of the polarizing film 30) will be described.

FIG. 4 is a diagram for explaining the bonding operation of the polarizing film 30 in the film member bonding apparatus 1 according to the first embodiment. Among them, Fig. 4(a) shows the state before the pasting operation starts. Here, this state is used as the initial state. In this initial state, the table 20 is located closer to the left side in the figure (START position) than the pressing roller 140 (the first pressing roller 141 and the second pressing roller 142 ). In the initial state, the glass substrate 10 (first glass substrate 10) as the object to be adhered at this time is placed at a predetermined position on the table 20. In addition, the amount of movement of the table 20 from the starting position along the x-axis, the position along the y-axis, and the angle around the z-axis (angle on the plane), etc., have been appropriately adjusted.

The front end portion (not shown) of the release film 40 on the winding side is connected to a winding roller (not shown) for winding the release film, and at this time, a polarizing film (first polarizing film) to be attached 30A) The front end portion 30a has reached the peeling roller 110. In this initial state, the pressing roller 140 (the first pressing roller 141 and the second pressing roller 142) is separated (located above) from the plane (xy plane) included in the glass substrate 10 placed on the table 20.

In the initial state shown in FIG. 4(a), first, the step of moving the table 20 is performed. That is, the control device 200 controls the table 20 to travel along the x axis to the right (arrow x direction) by a predetermined amount of movement. As a result, the table 20 moves to the position shown in FIG. 4(b) (starting position of the pasting operation). Specifically, the control device 200 controls the table 20 to travel in the right direction along the x axis, so that the sticking start end 10 a of the glass substrate 10 reaches a position facing the pressing point P of the pressing roller 140.

Once the table 20 is moved to the starting position of the pasting operation shown in FIG. 4(b), the pasting of the polarizing film 30 after the release film 40 is peeled off by the peeling roller 110 reaches the glass substrate 10. Steps at the beginning 10a. That is, the control device 200 controls the feed mechanism section 126 so that the polarizing film 30 reaches the sticking starting end 10 a of the glass substrate 10 (thin film member supply control). Thereby, the feed mechanism part 126 clamps the release film 40 by the gripper 127, and advances the release film 40 toward the release film travel direction (arrow x direction in the figure) according to a predetermined movement amount.

After the release mechanism 40 advances the release film 40 in the advancing direction of the release film by a predetermined amount of movement, the release film 40 is peeled off the first polarizing film 30A by the peeling roller 110, and the release film 40 is peeled off. The first polarizing film 30A of the type film 40 will travel along the guiding surface 131 of the guiding member 130, and then, the front end portion 30a of the first polarizing film 30A will reach the bonding start end 10a of the first glass substrate 10 (refer to FIG. 4( b)).

At this time, the control device 200 controls the feed mechanism unit 126 based on the image data captured by the camera 150. As an example of the control performed by the control device 200 on the feeding mechanism unit 126, as described above, the control device 200 monitors the rear of the polarizing film (first polarizing film 30A) to be adhered at this time based on the shooting data from the camera 150 The position of the end portion 30b (notch C1), and the feed mechanism portion 126 is operated until the position of the rear end portion 30b (notch C1) reaches the target position. As a result, the front end portion 30a of the first polarizing film 30A reaches the adhesion starting end 10a of the first glass substrate 10. In this way, once the front end portion 30a of the first polarizing film 30A reaches the sticking starting end 10a of the first glass substrate 10, the control device 200 controls the feed mechanism portion 126 to release the clamping of the release film 40. Then, the feed mechanism part 126 returns to the position at the initial state.

Once the feed mechanism section 126 advances the release film 40 in the direction in which the release film travels, the tension adjustment roller 125 will be, for example, as shown in FIG. 4(b) from the position shown by the dotted line (the tension in FIG. 4(a)). (The position of the adjustment roller 125) The lowering operation is performed in accordance with the movement amount of the feed mechanism portion 126. By providing the tension adjusting roller 125, it is possible to perform the winding operation of the release film 40 by the winding roller (not shown) without supplying the polarizing film 30 by the feeding mechanism section 126. In the case of synchronization, each work is performed independently of each other. It is sufficient to perform the winding operation of the release film 40 by the winding roller (not shown) when the fall amount of the tension adjusting roller 125 reaches a predetermined amount. Once the winding roller (not shown) starts winding the release film 40, the tension adjusting roller 125 returns to the original position (for example, the position shown in FIG. 4(a)).

When the release mechanism 40 advances the release film 40 in the direction in which the release film travels, the movement of the release film 40 is folded back by the peeling roller 110, so that not only friction on the surface of the release film 40 can occur. In this case, it is possible to prevent the release film 40 from being damaged, and it is also possible to prevent the abrasion of the folded-back portion (peeling roller 110 ).

That is, in the film member sticking apparatus 1 according to the first embodiment, the folded portion for peeling off the release film 40 from the polarizing film 30 is provided as a roller (peeling roller 110), and by using the peeling roller 110 After the release film 40 is folded back, it travels to peel the release film 40 from the polarizing film 30. Thereby, when performing the work of peeling off the release film 40 from the polarizing film 30, it is possible to prevent the folded portion (peeling roller 110) from being worn while preventing the release film 40 from being damaged.

In addition, since the guide surface 131 of the guide member 130 is provided with a non-adhesive surface treatment for preventing adhesion of the adhesive, when the polarizing film 30 peeled off the release film 40 travels on the guide surface 131 of the guide member 130, it is possible When the adhesive surface of the polarizing film 30 from which the release film 40 has been peeled off does not adhere to the guide surface 131 of the guide member 130, the polarizing film 30 is smoothly advanced.

Once the front end portion 30a of the first polarizing film 30A reaches the adhesion starting end 10a of the glass substrate 10, a step of moving (lowering) the pressing roller 140 is performed, so that the front end portion 30a of the polarizing film 30 is pressed by the pressing roller 140 The glass substrate 10 is pasted on the starting end 10a. As a result, after the pressing roller 140 (the first pressing roller 141 and the second pressing roller 142) descends, the pressing point P of the first pressing roller 141 presses the tip portion 30 a of the polarizing film 30 against the glass substrate 10 and sticks it together. At the beginning 10a (refer to FIG. 4(c)). As a result, the first polarizing film 30A is positioned on the sticking starting end 10a of the glass substrate 10. At this time, the second pressing roller 142 is in a state of pressing the first pressing roller 141.

Next, starting from the state shown in FIG. 4(c) (the state where the front end portion 30a of the polarizing film 30 is pressed against the sticking start end 10a of the glass substrate 10), a step of moving the table 20 is performed to The starting end 10 a of the substrate 10 is used as a starting point to attach the polarizing film 30 to the glass substrate 10. That is, starting from the state shown in FIG. 4(c), by moving the table 20 along the x axis in the direction of the arrow x′ (left direction in the figure), the first glass substrate 10 The pasting starting end 10a is used as a starting point for pasting. At this time, since the pressing roller 140 is kept pressed against the first polarizing film 30A, when the table 20 moves in the direction of the arrow x′ (left direction in the figure), the first pressing roller 141 moves forward. When the hour hand rotates, the second pressing roller 142 presses the first polarizing film 30A against the glass substrate 10 while rotating counterclockwise.

When performing the sticking operation shown in FIG. 4( d ), the fixed tension from the tension adjusting roller 125 is always applied to the release film 40. Therefore, during the adhesion operation of the first polarizing film 30A, the tension adjusting roller 125 is further lowered from the dotted line position in FIG. 4 (d), for example, so that the release film 40 is removed from the first polarizing film 30A Peel off. In this case, the winding operation of the release film 40 by the winding roller (not shown) may be set to start the winding operation when the amount of decrease of the tension adjustment roller 125 reaches a predetermined amount.

By providing such a tension adjusting roller 125, it is possible to independently perform the movement operation of the table 20 and the winding operation of the release film 40 performed by the winding roller without performing synchronization of the movement operation of the table 20 To do their homework.

In addition, even when performing the above-mentioned pasting operation, since the release film 40 travels after being folded back by the peeling roller 110, the surface of the release film 40 does not generate friction, thereby preventing damage to the release film 40, not only In this way, it is possible to prevent the abrasion of the folded-back portion (peeling roller 110) while preventing the abrasion of the peeling portion (peeling roller 110).

Once the table 20 moves further from the state shown in FIG. 4(d) in the direction of arrow x', it returns to the position shown in FIG. 4(a) (the same position as in the initial state). As a result, the step of attaching the first polarizing film 30A to the first glass substrate 10 is completed. Next, an adhesion step of the polarizing film (second polarizing film 30B) to the next glass substrate (second glass substrate 10) will be performed. When performing the pasting step of pasting the second polarizing film 30B on the second glass substrate 10, first remove the first glass substrate 10 that has completed the pasting step of the first polarizing film 30A from the table 20, and then After the two glass substrates 10 are placed on the table 20, the steps shown in FIGS. 4(a) to 4(d) are performed. By repeating these steps, the polarizing film can be adhered to each glass substrate in sequence.
