Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an adhesive cleaning device and a film laminating device including the adhesive cleaning device.

The present invention relates to a tacky cleaning device and a film laminating apparatus including the same. More particularly, the present invention relates to an adhesive cleaning apparatus including a pressure roller and a film laminating apparatus including the same.

For example, in order to produce various optical members such as a touch sensor, a polarizing plate, and a window substrate, a roll-to-roll type film laminating apparatus has recently been utilized.

In the film laminating process, the mutual bonding process of the film sheets is repeated, and a cleaning process for removing the foreign substance attached to the film sheet is required.

For the cleaning process, for example, a sticking roller or an adhesive roller on which an adhesive tape is wound or attached may be brought into contact with the film sheet to remove foreign matter. However, if the cleaning process is repeated, the removal efficiency of the foreign material drops, and thus the process of replacing the adhesive roller or the adhesive tape is performed. Thus, the cleaning process may reduce the efficiency of the entire film laminating process.

Therefore, there is a need to develop a method that increases the efficiency of the entire film laminating process by reducing the cost and time of the cleaning process.

For example, Korean Patent Publication No. 10-0454651 discloses a roller type cleaner with an adhesive tape, but does not provide a method for improving the efficiency of the cleaning process described above.

Korean Patent Registration No. 10-0454651

<Adhesive Cleaning Device>

1 is a schematic view for explaining an adhesive cleaning apparatus according to exemplary embodiments of the present invention. 2 is an enlarged view of an adhesive roller unit according to exemplary embodiments.

Referring to FIG. 1, the adhesive cleaning apparatus may include an adhesive roller unit 100, film feeders 230 and 240, fixing bars 210 and 220, and a supporter 200.

The adhesive roller unit 100 can be fixed on both sides of the pair of supporters 200, for example.

In some embodiments, the film supply unit may include a first film supply unit 230 and a second film supply unit 240. The first film supply unit 230 and the second film supply unit 240 may be disposed at upper and lower portions of the adhesion roller unit 100 to allow the target film to pass through the adhesion roller unit 100.

The first film supply unit 230 and the second film supply unit 240 have a roller structure and can move the target film to pass through the adhesion roller unit 100. The first film supply unit 230 and the second film supply unit 240 may be coupled to the first and second fixing bars 210 and 220, respectively. The first fixing bar 210 and the second fixing bar 220 may be connected to the supporter 220 through a coupling member or may be provided as an integral member with the supporter 220.

Referring to FIG. 2, the adhesive roller unit 100 may include an adhesive roller 120, a housing 110, and a rotation unit 160.

According to exemplary embodiments, the tacking roller 120 may include a first tacking roller 120a and a second tacking roller 120b. The first adhesive roller 120a and the second adhesive roller 120b may be fixed within the housing 110 and disposed to face each other.

For example, the adhesive rollers 120 can be fixed through the fixing portions 127 formed on both sides of the housing 110, respectively, fitted into the support shaft 125. The fixing portion 127 may include, for example, an insertion hole formed on both sides of the housing 110. [

As shown in FIG. 2, the housing 110 may have a rectangular cross section or a rectangular parallelepiped shape having open top and bottom surfaces, but the shape of the housing 110 is not particularly limited.

A shaft 130 is extended from both sides of the housing 110 and the adhesive roller unit 100 is fixed to the supporter 200 through the shaft 130 and the brackets 150 and 155, As shown in FIG.

For example, a first bracket 150 and a second bracket 155 are disposed on both sides of the adhesive roller unit 100, and the shaft 130 is connected to the first bracket 150 and the first bracket 150 through the bearing unit. And the second bracket 155, respectively.

For example, the shaft 130 may be engaged with the first bracket 150 through the first bearing unit 140 at the right side of the adhesion roller unit 100. [ Further, the shaft 130 may be engaged with the second bracket 155 through the second bearing unit 145 at the left side of the adhesion roller unit 100. [

According to exemplary embodiments of the present invention, the adhesive roller unit 100 includes a rotation unit 160, and the housing 110 can be rotated through the shaft 130 by the rotation unit 160. For example, the rotation unit 160 may be designed so that the housing 110 sequentially rotates or continuously rotates by a predetermined unit angle.

The rotating portion 160 may include, for example, a handle coupled with the bearing unit. The rotation unit 160 may be coupled to at least one of the first bearing unit 140 or the second bearing unit 145. [ 2, the rotation unit 160 is shown coupled to the second bearing unit 145. However, the position of the rotation unit 160 is not limited thereto.

3A to 3D are schematic views for explaining the structure of the adhesive roller according to the exemplary embodiments and the coupling with the housing.

3A, the adhesive roller 120 may include a core portion 122 into which the support shaft 125 is inserted and an adhesive sheet 124 wound on the core portion 122. [ As shown in Fig. 3A, the adhesive sheet 124 may be wound in a multilayer structure on the core portion 122. Fig.

The adhesive sheet 124 includes, for example, a silicone-based adhesive polymer, and can remove dust and foreign substances adhering to the target film by contacting with the target film.

Referring to FIG. 3B, the outer surface of the adhesive sheet 124 may include an indentation 126 formed to be detachable as a unit sheet. The section reduction 126 may include, for example, perforations and may be formed by perforating a multi-layered adhesive sheet 124 toward the center of the core portion 122.

Referring to FIG. 3C, the support shaft 125 is inserted through the core 122 of the first adhesive roller 120a and the second adhesive roller 120b wound around the adhesive sheet 124 formed with the cut- Can be inserted.

Referring to FIG. 3D, the first adhesive roller 120a and the second adhesive roller 120b may be fixedly received through the support shaft 125 so as to face each other inside the housing 110.

When the housing 110 is rotated by the rotation unit 160, the adhesion rollers 120 fixed to the housing 110 may rotate together.

4 is a schematic view for explaining an increase in contact area or tension with respect to a target film as the housing rotates.

4, the object film 50 is supplied from the film supply units 230 and 240 shown in FIG. 1, and is contacted with the adhesion rollers 120 accommodated in the housing 110 to face each other, The process can be carried out.

For example, the extension line between the extension direction of the object film 50 and the center of the adhesive rollers 120 in step S10 may intersect substantially perpendicularly.

As described above, when the cleaning process is repeated and the foreign substance removing force of the adhesive sheet 124 is excessively reduced, the unit sheet of the adhesive sheet 124 can be peeled off through the section 126. Therefore, a cleaning process by a new unit sheet can be started.

However, when the separation of the unit sheets is repeated, the thickness of the adhesive sheet 124 may decrease, and the distance between the adhesive rollers 120 may increase. In this case, the tension applied to the target film 50 may be reduced, or the contact area between the target film 50 and the adhesion roller 120 may be reduced, thereby decreasing the cleaning efficiency.

According to embodiments of the present invention, the housing 110 can be rotated at a predetermined angle through the rotation unit 160 before the cleaning efficiency is reduced (e.g., step S20). In this case, the arrangement of the extension line between the centers of the adhesive rollers 120 and the extending direction of the object film 50 is twisted, and the tension applied to the object film 50 can be increased again. In addition, the contact area of the object film 50 and the adhesion roller 120 can be increased.

Therefore, even if the peeling process of the adhesive sheet 124 is repeated, the tension in a desired range is maintained, and the cleaning process for the target film 50 can be continued while maintaining the cleaning efficiency for a long time.
