Description

Glass transmission structure

The present disclosure relates to a glass transmission structure, and more particularly to a glass transmission structure having sidebands.

With advances in glass production technology, glass can be less than 200 microns thick and flexible and rollable. Utilizing the excellent optical properties of glass, the stability of temperature and geometry, and the roll-to-roll process, this ultra-thin glass substrate can be used in electronic paper, flexible solar cells, In touch panels, organic light-emitting diode displays and other products.

However, although ultra-thin glass has flexibility, it still has glass hard and brittle properties. When transported by a roller in a roll-to-roll production process, it is not possible to automatically adjust the deformation to absorb stress as a conventional plastic substrate. Ultra-thin glass is prone to excessive stress and deformation, causing defects or extending and expanding existing defects, eventually leading to glass breakage.

The present disclosure relates to a glass transfer structure. In one embodiment, the glass is prevented from being damaged by excessive stress during the process of crimping the glass transfer structure.

According to an embodiment of the present disclosure, a glass transmission structure is proposed. The glass transmission structure includes a glass and two sidebands. Glass has one of the first Long side and a second long side. The two side straps are respectively fixed to the first long side and the second long side of the glass, and the two side strips each have a plurality of through holes and include a plurality of tongues, each of the tongues being connected to an edge of the corresponding through hole.

In order to better understand the above and other aspects of the present disclosure, the following specific embodiments, together with the accompanying drawings, are described in detail below:

Please refer to FIG. 1 , which is a cross-sectional view showing a glass transmission structure according to an embodiment of the present disclosure. The glass transmission structure 100 includes a glass 110 and two sidebands 120.

The glass 110 can be used in display fields, touch fields, or other products that require glass. At least one layer of electronic components (not shown) may be formed on the glass 110, and the electronic components may conform to the functional requirements of the product. For example, when the glass is applied to a touch device, the electronic component may be a touch sensing structure formed by a sputtering process.

The glass 110 has a first surface 110s1 and a second surface 110s2 opposite to each other. At least one of the two sidebands 120 is fixed to at least one of the first surface 110s1 and the second surface 110s2 of the glass 110, wherein the sideband 120 is fixed to The method of the first side 110s1 and/or the second side 110s2 of the glass 110 is, for example, adhesive. Although not shown, an adhesive can bond the glass 110 to the sidebands 120. The two sidebands 120 of the embodiment are illustrated by being fixed to the first surface 110s1 and the second surface 110s2 of the glass 110.

In addition, the thickness t1 of the glass 110 may be less than 200 micrometers, which belongs to the category of ultra-thin glass. The thickness t1 of the glass 110 of the embodiment is exemplified by 100 micrometers. However, the thickness t1 of the glass 110 of another embodiment is also can More than 200 microns.

The thickness t2 of the side band 120 is between about 50 and 200 microns, and the side band 120 protrudes from the long side edge of the glass 110 by a length L1 of about 10 mm or other value, and the length L2 of the side band 120 in contact with the glass 110 is about 10 mm or other value.

Referring to FIG. 2, a cross-sectional view of a glass transmission structure in accordance with another embodiment of the present disclosure is shown. In this embodiment, the double sideband 120 is only fixed to the second side 110s2 of the glass 110. However, the disclosed embodiment is not limited thereto. In another embodiment, one of the two sidebands 120 may be fixed only to one of the first side 110s1 and the second side 110s2 of the glass 110, and the other of the two sidebands 120 may be fixed only to the glass 110. One of the first side 110s1 and the second side 110s2.

Please refer to FIG. 3, which is a plan view of FIG. The glass 110 has a first long side 111 and a second long side 112 opposite thereto, wherein the long side refers to the direction in which the reel extends the glass 110. The two side bands 120 are respectively fixed to the first long side 111 and the second long side 112 of the glass 110. The two side bands 120 each have a plurality of through holes 120a and include a plurality of tongues 121. One side of each of the tongue pieces 121 is connected to the side. Corresponding to one edge 122 of the through hole 120a, and the opposite side of the tongue 121 is freely movable, wherein the edge 122 extends substantially in the width direction of the glass 110. In another embodiment, one side of each tongue 121 can be connected to the edge 123 of the corresponding through hole 120a, wherein the edge 123 is opposite to the edge 122. In this design, the opposite side of the tongue 121 is also freely activity.

In this embodiment, the through hole 120a is an elliptical hole, but the through hole 120a of another embodiment may be a circular hole, a hole formed by an arbitrary curve or a polygonal hole, wherein the polygonal hole is, for example, a triangular hole, a rectangular hole or other geometric type. Polygon holes.

In addition, although the through holes 120a of the side bands of the embodiment are illustrated as being arranged in a single row, the through holes 120a of the other side bands may be arranged in multiple rows; or, one of the two sidebands They can be arranged in a single row while the other can be arranged in multiple rows.

Further, the material of the side belt 120 is made of a flexible material or a soft material, so that the side belt 120 is deformable. In one embodiment, the material of the sideband 120 is, for example, Polyimide, polyethylene terephthalate (PET) or polyethylene naphthalate (PEN).

Please refer to FIG. 4 , which illustrates a schematic view of the glass transmission structure of FIG. 1 mounted on the tow wheel 130 . The two side belts 120 are respectively disposed on the two tow wheels 130, so that the glass transmission structure 100 can be transmitted by the tow wheel 130. Each of the tow wheels 130 includes a plurality of bumps 131. When the tow wheel 130 rotates, at least one of the bumps 131 is aligned in the corresponding through hole 120a of the side band 120, thereby rolling and straightening the glass transmission structure 100. Due to the use of the tow wheel 130, the glass transmission structure 100 is less offset during the rolling of the glass transport structure 100, or the offset can be controlled within a preset range. In addition, when the material of the sideband 120 is flexible or soft, once the glass transmission structure 100 is displaced during the rolling of the glass transmission structure 100, the sideband 120 can adjust or allow moderate deformation to absorb the bias. The stress caused by the migration prevents the stress from directly acting on the glass, causing the glass to break due to stress. According to the experimental analysis data, when the length of the glass 110 is 475 cm, the width is 250 cm, and the thickness is 0.1 cm, the maximum stress is reduced by about 19.5% due to the design of the sideband 120 (compared to the omission of the sideband 120). ).

Please refer to FIG. 5 (the through hole 120a and the tongue 121 are not shown), and The external view of the glass transfer structure shown in Fig. 4 is curled. When the trailing wheel 130 (Fig. 4) is rotated, the glass transport structure 100 can be rolled to cause the glass transport structure 100 to be rolled into the state as shown in Fig. 5.

Please refer to Fig. 6, which shows a cross-sectional view in the direction 6-6' in Fig. 5. After the sidebands 120 are disposed on the tow wheel 130, the tongues 121 of the sidebands 120 are pushed up by the bumps 131 of the tow wheel 130 (the bumps 131 are not shown in FIG. 6) and are turned out to be located on the adjacent two sidebands. Between 120. The two sidebands 120 of the crimped glass transfer structure form a multi-layer laminate, wherein the opposite tabs 120' and 120" of the crimped sideband 120 are flipped over and positioned in the opposite second layer 120. Between 'and 120', the distance between the two layers 120' and 120" can be widened, so that the spacing between adjacent two glasses 110 is enlarged and not easily contacted with each other or the contact is too tight to break into the glass. The electronic component (not shown) on the other side of the sideband 120 of the opposite side may be similar to the orientation of the tongue 121 of FIG. 6, and will not be described again.

Please refer to FIG. 7 , which illustrates an external view of a glass transmission structure according to another embodiment of the present disclosure. The orientation of the tongue 121 of this embodiment differs from the orientation of the tongue 121 of FIG. 6 by 180 degrees and is ejected upward. The orientation of the tongue 121 on the side belt 120 of the other opposite side may be similar to the orientation of the tongue 121 of FIG. 7, and will not be described again.

Please refer to FIG. 8 , which illustrates an external view of a glass transmission structure according to another embodiment of the present disclosure. One side of the tab 121 of the side band 120 is attached to the edge 124 of the through hole 120a, and the opposite side of the tongue 121 is free to move, wherein the edge 124 extends substantially along the length of the glass 110. Since the tongue 121 of the sideband 120 of the present embodiment is turned out in the direction of the glass 110, the tongue 121 is brought closer to the middle of the adjacent two glass 110. The position (in comparison with the tongue 121 being turned out in the outer direction of the side band 120), and the spacing between the adjacent two glasses 110 is further enlarged to prevent the adjacent two glasses 110 from contacting each other or avoiding the contact being too tight and breaking to the glass. Electronic components on 110 (not shown).

Please refer to FIG. 9 , which illustrates a top view of a glass transmission structure in accordance with another embodiment of the present disclosure. In this embodiment, one side of the tongue 121 of the side band 120 is connected to the edge 125 of the through hole 120a, and the other side of the tongue 121 is free to move. In summary, the tongue 121 of the sideband 120 can be attached to either edge of the through hole 120a, and the disclosed embodiment is not limited.

Please refer to FIG. 10, which illustrates a top view of a glass transmission structure in accordance with an embodiment of the present disclosure. At least one of the two sidebands 120 has a plurality of through holes 120a1 and a plurality of openings 120a2. The openings 120a2 are distributed outside the sidebands 120 and are located between the adjacent two through holes 120a1. The aperture of the opening 120a2 is smaller than the aperture of the through hole 120a1. The opening 120a2 increases the flexibility of the sideband 120, helping the glass transmission structure 100 to curl. When the trailing wheel 130 (Fig. 4) is rotated, since the opening 120a2 increases the flexibility of the side belt 120, the glass transmission structure 100 is also less prone to stress concentration and causes the glass 110 to be broken.

Please refer to FIG. 11 , which illustrates a top view of a glass transmission structure in accordance with an embodiment of the present disclosure. The glass transmission structure 200 includes a glass 110 and two sidebands 220.

The two side strips 220 are respectively fixed to the first long side 111 and the second long side 112 of the glass 110. The two side strips 220 each have a plurality of long through holes 221 extending along the width direction of the glass 110. In another embodiment, each of the elongated through holes 221 may also extend along the length of the glass 110.

Although not shown, the glass transmission structure 200 can be disposed on the tow wheel 130. When the tow wheel 130 rotates, at least one of the protrusions 131 of the tow wheel 130 is aligned with the corresponding elongated hole 221 to The glass transmission structure 100 is driven and straightened. Due to the design of the long through hole 221, the flexibility of the connecting portion 222 between the adjacent two long through holes 221 is increased, and the tolerance of the offset can be increased, so that the drag wheel 130 is rolled up during the process of rolling the glass transmission structure 200. Even if the glass transfer structure 200 is displaced, the connecting portion 222 can be easily deformed to avoid the problem of excessive stress concentration of the side band 220.

In another embodiment, some of the elongated through holes 221 may be replaced by the through holes 120a, for example, some or all of the long through holes 221 of one side of the strip 120 are replaced by the through holes 120a; or some strips of the two side bands 120 are strips The through hole 221 is replaced by a through hole 120a.

In summary, although the disclosure has been disclosed in the above embodiments, it is not intended to limit the disclosure. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the disclosure. Therefore, the scope of protection of this disclosure is subject to the definition of the scope of the appended claims.
