Description
本発明は、ロールから繰り出された光学フィルムをガラス基板に貼り合わせるロール・ツー・パネル(Roll to Panel)技術に関し、特に、緩衝材付き搬送車輪を備えるガラス基板搬送装置に関する。
The present invention relates to a roll-to-panel technique in which an optical film fed out from a roll is bonded to a glass substrate, and more particularly, to a glass substrate transport apparatus including a transport wheel with a buffer material.
従来、光学表示装置が広く製造されている。光学表示装置に用いられるガラス基板には、光の透過または遮断を制御するために、光学フィルムが貼合わせられるのが通常である。ガラス基板に光学フィルムを貼合わせる最も効率的な方法としては、ロールから繰り出された光学フィルムを、ガラス基板に応じたサイズにカットした後、該光学フィルムを連続的にガラス基板に貼合わせる、いわゆるロール・ツー・パネル(以下、RTPと略称する)方式が挙げられる。当該方法によれば、高い生産効率にて貼合わせが可能となる。
Conventionally, optical display devices have been widely manufactured. In order to control transmission or blocking of light, an optical film is usually bonded to a glass substrate used for an optical display device. As the most efficient method of laminating an optical film on a glass substrate, the optical film fed from a roll is cut into a size corresponding to the glass substrate, and then the optical film is continuously laminated on the glass substrate, so-called One example is a roll-to-panel (hereinafter abbreviated as RTP) system. According to this method, bonding can be performed with high production efficiency.
RTP方式の例として、特許文献1に、光学フィルムが巻き取られて形成されたロール(図示せず)から光学フィルムを連続的に繰り出しながら、ガラス基板のサイズに合わせて光学フィルムに切り込みを入れ、二つの切り込み間に形成されるシート状の光学フィルムをガラス基板に貼り合せるRTPシステムが開示されている。

Paste together while passing through 1. The glass substrate 1 to which the optical film that has passed through the bonding rollers 54B and 54B is attached is conveyed to the next step by the plurality of conveying means 51B. At this time, since the edge of the glass substrate 1 collides with the conveying means 51B (corresponding to the second conveying means of the present invention) immediately after passing through the bonding rollers 54B, 54B, the conveying means 51B is easily damaged and damaged. There existed a subject that the glass substrate 1 and the optical film affixed by the means 51B will be damaged.

FIG. 2 shows the configuration of the glass substrate transfer apparatus according to the present invention. As shown in FIG. 2, the glass substrate transport apparatus includes a plurality of first transport units arranged in the same horizontal direction, a first transport unit that transports the glass substrate, and an optical (not shown) that feeds out the optical film. A roll of film (an example of a feeding means), a peeling means for peeling a carrier film (also referred to as a release film) from the optical film, and a glass that is transported by the first conveying means for the optical film from which the carrier film has been peeled off Affixing means and a plurality of second transport units are arranged along the same horizontal direction, which is composed of a pair of adhering rollers arranged to face each other with a predetermined interval therebetween for adhering to the substrate.

なお、図2(a)において、第1搬送ユニット及び第2搬送ユニットがそれぞれ3つしか図示されていないがこれに限定しなく、ガラス基板のサイズに合わせて3つ以上になってもよい。
In FIG. 2A, only three first transport units and two second transport units are shown, but the present invention is not limited to this, and the number may be three or more according to the size of the glass substrate.
第1搬送ユニットは、図2(b)に示すように、複数の同一形状の樹脂製車輪が一つの回転軸に所定間隔を開けて並べて構成される。なお、樹脂製車輪は3つしか図示されていないがこれに限定しなく、ガラス基板のサイズに合わせて3つ以上になってもよい。また、各車輪が回転軸に着脱可能に取り付けてもよく、回転軸と一体成形してもよい。そして、車輪の材質として、樹脂製を例として説明したがこれに限定しない。
As shown in FIG. 2B, the first transport unit is configured by arranging a plurality of resin wheels having the same shape on a single rotating shaft with a predetermined interval. In addition, although only three resin wheels are illustrated, the present invention is not limited to this, and may be three or more according to the size of the glass substrate. Each wheel may be detachably attached to the rotating shaft, or may be integrally formed with the rotating shaft. And although the resin-made material was demonstrated as an example as a material of a wheel, it is not limited to this.
従来における、一対の貼り合わせローラを通過した直後のガラス基板が、第2搬送手段における車輪と衝突して車輪が削れてしまい、削れた車輪がガラス基板や貼り付けられた光学フィルムに傷を入れる課題に対して、本発明の第2搬送手段は、図2(c)示すように、図2(b)に示すような第1搬出手段に弾性体(緩衝材の一例)をさらに設けて構成される。即ち、第2搬送手段は、ガラス基板の表面に接触する第1搬送手段のような各車輪の外周面に、内周が面状で全体的にリング状に形成された弾性体をその弾性力を利用して緊張に装着して構成される。この場合、第1搬送手段の第1搬送ユニットと、弾性体以外の第2搬送手段の第2搬送ユニットとの構成・形状が同一であるため、共通性があり、第2搬送手段のための第2搬送ユニットを別途製造する必要がなくなる。
Conventionally, a glass substrate immediately after passing through a pair of bonding rollers collides with a wheel in the second conveying means and the wheel is scraped, and the scraped wheel damages the glass substrate and the attached optical film. In response to the problem, the second conveying means of the present invention is configured by further providing an elastic body (an example of a cushioning material) on the first carrying-out means as shown in FIG. 2 (b), as shown in FIG. 2 (c). Is done. In other words, the second conveying means applies an elastic body formed on the outer peripheral surface of each wheel such as the first conveying means that contacts the surface of the glass substrate, with the inner periphery being planar and formed in a ring shape. It is composed by using tension. In this case, since the configuration and shape of the first transport unit of the first transport unit and the second transport unit of the second transport unit other than the elastic body are the same, there is commonality, and There is no need to manufacture the second transport unit separately.
なお、第2搬送手段の樹脂製車輪は3つしか図示されていないがこれに限定しなく、ガラス基板のサイズに合わせて3つ以上になってもよい。また、各車輪が回転軸に着脱可能に取り付けてもよく、回転軸と一体成形してもよい。そして、車輪の材質として、樹脂製を例として説明したがこれに限定しない。
Although only three resin wheels are shown in the second conveying means, the present invention is not limited to this. The number may be three or more according to the size of the glass substrate. Each wheel may be detachably attached to the rotating shaft, or may be integrally formed with the rotating shaft. And although the resin-made material was demonstrated as an example as a material of a wheel, it is not limited to this.
また、弾性体の内周が面状であり、各車輪の外周面も面状であり、両方の接触面が大きく、且つ、弾性力によって緊張状態に装着されるので、両方間の摩擦力が大きいので、弾性体が車輪の外周面から外れることが難しくなる。弾性部材は、一対の貼り合わせローラの直後の第2搬送手段の最初に配置された第2搬送ユニットのみに設けてもよいが、ガラス基板1枚分相当の長さにあたる第2搬送手段における第2搬送ユニットごとに装着されることが好ましい。
In addition, the inner periphery of the elastic body is planar, the outer peripheral surface of each wheel is also planar, both contact surfaces are large, and are attached in tension by elastic force, so the frictional force between both is Since it is large, it becomes difficult for the elastic body to come off from the outer peripheral surface of the wheel. The elastic member may be provided only in the second transport unit disposed at the beginning of the second transport unit immediately after the pair of bonding rollers, but the second member in the second transport unit corresponding to a length corresponding to one glass substrate. It is preferable to install every two transport units.
