Description

Jointing device

The present invention relates to a joining apparatus for applying a glue and an optical elastic resin between two panels during the manufacture of a flat panel display and joining the two panels to each other.

Some flat panel displays include a touch screen device that is an input device for a user to enter commands via a display with a hand or object. A touch screen device is provided on the front surface of the flat panel display. The function of the touch screen device is to convert the position where the user touches the hand or the object into a telecommunication signal.

The methods of implementing touch screen devices are classified into several well-known types, including electrostatic capacitance, light sensing, and resistive.

A method of generally manufacturing a flat panel display having such a touch screen device includes bonding a cover panel (eg, a tempered glass panel or an acrylic panel) to a display panel (eg, a liquid crystal display module, an organic light emitting diode module, or the like) By).

Furthermore, an air layer is formed between the display panel and the cover panel to protect the display panel from such impact even when the cover panel is damaged by an external impact. However, the air layer can cause light scattering, thereby reducing the brightness or contrast of the flat panel display, resulting in poor visibility.

In order to overcome the above problems, a technique of filling a space between a display panel and a cover panel with an optical elastic resin (SVR) instead of an air layer has been proposed. Optics The elastic resin adjusts the refractive index, thereby reducing the scattering of light. Thus, a flat panel display having an SVR layer can significantly reduce light loss, thereby enhancing brightness or contrast of the display, as compared to conventional flat panel displays having an air layer between the display panel and the cover panel. Further, the optical elastic resin has a predetermined elasticity and acts to absorb an impact. Therefore, a flat panel display having an SVR layer can reduce the possibility of damage to the cover panel compared to a conventional flat panel display having an air layer between the display panel and the cover panel. In addition, even if the cover panel is damaged (for example, broken), the cover panel is prevented from being scattered due to the cover panel being attached to the SVR layer.

A flat panel display in which an SVR layer is formed between a display panel and a cover panel includes a coating gel to a display panel or a cover panel, a coated optical elastic resin to a display panel or a cover panel, and a bonded cover panel and a display panel.

However, in the conventional art, the above-described operation of manufacturing a flat panel display is performed using separate devices. Therefore, the system for manufacturing a flat panel display according to the conventional technology is quite complicated and the process efficiency is poor. Moreover, in the conventional technology, when the display panel and the cover panel are transferred to a plurality of devices, the positions of the display panel and the cover panel may be in error. In this case, the glue and/or the optical elastic resin cannot be properly applied to the display panel or the cover panel. The display panel and the cover panel may not be precisely aligned during the bonding operation.

Accordingly, the present invention has been made in view of the problems of the prior art, and it is an object of the present invention to provide an engaging device configured to enable a single device to perform a series of operations, including applying glue to a display panel or a cover panel. The operation of applying the optical elastic resin to the display panel or the cover panel and the operation of bonding the cover panel to the display panel.

Another object of the present invention is to provide an engaging device that can apply a glue and an optically elastic resin to precise positions on a display panel or a cover panel.

It is still another object of the present invention to provide an engaging device that can precisely align a display panel and a cover panel with each other and engage each other.

Still another object of the present invention is to provide an engaging device in which a display panel and a cover panel can be pressed toward each other at a preset optimum pressure when the display panel and the cover panel are joined to each other.

In order to achieve the above object, the present invention provides an engaging device comprising: a chamber unit in which an engaging program for joining a first panel to a second panel, a panel supporting unit, disposed on one side of the chamber unit, is performed in the chamber unit The panel supporting unit supports the first panel and the second panel, the coating unit, the coating glue and the optical elastic resin (SVR) supplied from the outside to the first panel and the panel supporting unit supported on the panel supporting unit, and is disposed at In the chamber unit, wherein the first panel and the second panel are loaded on the panel support unit to face each other, the panel transfer unit, and the first panel and the second panel are transferred from the panel support unit to the panel support unit, and The panel pressing unit presses the first panel toward the second panel, thereby joining the first panel to the second panel.

As described above, in the present invention, a single bonding apparatus can perform a series of operations including an operation of applying a glue to a display panel or a cover panel, an operation of coating an optical elastic resin to a display panel or a cover panel, and a cover panel. The operation of bonding to the display panel. Therefore, the present invention can enhance the bonding process effectiveness.

Furthermore, the bonding apparatus of the present invention can stably fix the display panel or the cover panel before applying the glue and the optical elastic resin to the display panel or the cover panel. Therefore, the bonding device can apply the glue and the optical elastic resin to precise positions on the display panel or the cover panel.

Further, in the bonding apparatus of the present invention, the image capturing unit is for monitoring whether the display panel and the cover panel are aligned with each other. If not aligned with each other, the rotational or horizontal position of the display panel or cover panel is adjusted so that the display panel can be accurately aligned with the cover panel. Therefore, the accuracy in joining each other can be improved.

Furthermore, in the engagement device of the present invention, the load sensor measures the pressure of the display panel and the cover panel against each other. Based on the measured pressure, the engagement pressure between the display panel and the cover panel can be maintained within a preset optimal range.

Hereinafter, preferred embodiments of the engaging device of the present invention will be described in detail with reference to the accompanying drawings.

The process of joining the first panel P1 to the second panel P2 is performed in the chamber unit 10. The panel supporting unit 20 is disposed on one side of the chamber unit 10. The first panel P1 and the second panel P2 supplied from the outside are supported by the panel supporting unit 20. The coating unit 30 applies a glue and an optical elastic resin to the first panel P1 supported by the panel supporting unit 20. The panel holder unit 40 is disposed in the chamber unit 10, and the first panel P1 and the second panel P2 are loaded to the panel holder unit 40, and the first panel P1 and the second panel P2 face each other.

The upper chamber plate 12 has been moved upwards away from the lower chamber plate 11 by a predetermined distance Thereafter, the first panel P1 and the second panel P2 are transmitted to the panel supporting unit 40 through the space between the lower chamber panel 11 and the upper chamber panel 12. Further, when the upper chamber plate 12 is moved downward and is in close contact with the lower chamber plate 11, the space between the lower chamber plate 11 and the upper chamber plate 12 can be isolated from the outside. In the present embodiment, the shape of the lower chamber plate 11 is a flat plate shape. The upper chamber plate 12 has a concave shape in which the lower chamber plate 11 is in an open form.

At least the lower chamber plate 11 or the upper chamber plate 12 is connected to the vacuum pump 15 by a vacuum tube member 16. After the lower chamber plate 11 and the upper chamber plate 12 have been in close contact with each other, the vacuum pump 15 operates to form a vacuum in the space between the lower chamber plate 11 and the upper chamber plate 12. Therefore, the process of joining the second panel P2 by the first panel P1 can be performed in a vacuum. The bubbles may be generated in the glue or the optical elastic resin applied to the first panel P1, but such bubbles may be eliminated from the glue or the optical elastic resin by vacuum.

Each locator 23 can include a roller, wherein the periphery of the roller is made of a soft material. For example, linear motors, ball shaft devices, or actuators that operate hydraulically or pneumatically A drive device can be used as the positioner moving device 24.

When the positioner 23 comes into contact with the opposite edge of the first panel P1, the first panel P1 can be reliably supported at the correct position of the first support member 21. Therefore, during the process of applying the glue and the optical elastic resin to the first panel P1, since the position of the first panel P1 can be fixed, the glue and the optical elastic resin can be applied to the precise position of the first panel P1.

As shown in FIG. 3, the coating unit 30 includes a coating head 31 and a coating head moving device 32. The coating head 31 includes a glue application nozzle 311 that applies the glue R1 to the first panel P1 and an SVR coating nozzle 312 that coats the optical elastic resin R2 to the first panel P1.
