Abstract

PURPOSE:To close the injection holes of many liquid crystal panels at one time and to enable the sure application of adhesives without sagging of liquid crystals by moving transfer pins stuck with the adhesives up to the injection holes of the liquid crystal panels and applying the adhesives to the injection holes of the liquid crystal panels. CONSTITUTION:An adhesive housing receiver 5 constituting a sealing unit 4 is vertically moved by, for example, an air cylinder with respect to a conveyor 1. The transfer pins 6 constituting the sealing unit 4 are so constituted as to adhere the adhesive in the adhesive housing receiver 5 to the injection holes of the liquid crystal panels and are constituted by supporting many pieces of the pins at the same intervals on a shaft body 7. The front ends of the pins are so constituted as to have ruggedness to allow the easy adhesion of the adhesives. The adhesives of the adhesive housing receiver 5 are stuck to the transfer pins when the liquid crystal panels 3 are transported to a prescribed point. The transfer pins 6 are then moved to the injection holes of the liquid crystal panels 3 and the adhesives are applied to the injection holes of the liquid crystal panels.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a liquid crystal adhesive coating device.

[0002]

2. Description of the Related Art Conventionally, in order to manufacture a liquid crystal panel used for a word processor, a television, etc., liquid crystal is injected through a liquid crystal injection hole between two glass plates whose periphery is fixed with an adhesive, and after that, A method of closing a liquid crystal injection hole of a liquid crystal panel with an adhesive has been implemented. By the way, conventionally, in order to close the liquid crystal injection hole of the liquid crystal panel in which liquid crystal is injected, about 30 liquid crystal panels are fitted and supported on a pallet, and the liquid crystal injection holes of the liquid crystal panel are bonded from nozzles while confirming the position with a camera. It is practiced to pour out the agent and close the liquid crystal injection hole with an adhesive. Here, the injection hole is configured to be located at the upper end of the panel.

[0003]

However, according to the liquid crystal adhesive application device having the above-mentioned structure, the liquid crystal injection hole of each liquid crystal panel is closed while checking the liquid crystal injection hole of each liquid crystal panel with a camera, which is equivalent to work. It has the drawback of requiring labor. In the above structure, the adhesive is hardened after the work of bonding all the liquid crystal panels, but since the work time from the first liquid crystal panel to the last liquid crystal panel takes about 5 minutes, the application work of the last liquid crystal panel is performed. At that time, there was a drawback that the adhesive of the first liquid crystal panel dripped.

The present invention has been made in view of the above points, and provides a liquid crystal adhesive coating device capable of closing the liquid crystal injection hole of a liquid crystal panel with good workability and preventing the adhesive from dripping. The purpose is to

[0005]

The present invention has the following constitution in order to solve the above problems. That is, according to the first aspect of the present invention, the pallet has a liquid crystal panel in which a large number of injection holes are fitted and supported, an adhesive container, and an adhesive of the adhesive container is attached to the injection holes of the liquid crystal panel. And a rotatable sealing unit provided with a large number of transfer pins.
Also, when the liquid crystal panel is conveyed to a predetermined location, the transfer pin rotates to attach the adhesive in the adhesive receiving tray, and after that, the transfer pin is moved to the injection hole of the liquid crystal panel for positioning and adhesion. The agent is applied to the injection hole of the liquid crystal panel.

[0006]

In the structure according to the above-mentioned claim 1, when the liquid crystal panel is conveyed to a predetermined position, the transfer pin rotates to attach the adhesive in the adhesive receiving tray, and the post-transfer pin is attached to the liquid crystal panel. Since the adhesive can be applied to the injection holes of the liquid crystal panel by moving to and positioning the injection holes of the liquid crystal panel, it is possible to block the injection holes of many liquid crystal panels at once. Further, since the adhesive application work for a large number of liquid crystal panels is instantaneously completed, the adhesive does not drip.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. In the figure, 1 is a conveyor attached to the apparatus main body, 2 is a pallet that is conveyed by the conveyor 1, 3 is a liquid crystal panel that is fitted and supported by a large number of pallets 2, and the pallet 2 has an injection hole facing downward. I am doing it.

Reference numeral 4 denotes a sealing unit which is rotatably constituted, and 5 denotes an adhesive accommodating receiver which constitutes the sealing unit 4, and is constituted to move up and down with respect to the conveyor 1 by an air cylinder, for example. is there. Reference numeral 6 denotes a transfer pin that constitutes the sealing unit 4, and is configured so that the adhesive of the adhesive storage receiver 5 is attached to the injection hole of the liquid crystal panel. A large number of transfer pins 6 are supported on the shaft body 7 at the same intervals. Further, the tip of the transfer pin 6 is formed to have unevenness so that the adhesive can be easily attached.

Reference numeral 8 is a bracket for supporting the shaft body 7 of the transfer pin, and 9 is a rotary cylinder for rotating the shaft body 7. Reference numeral 10 is a support plate for the adhesive storage receiver 5, 11 is a robot for moving the adhesive storage receiver 5, and 12 is a camera for finely adjusting the position of the liquid crystal panel fitted and supported on the pallet 2.

Further, in the liquid crystal adhesive applying device shown in FIGS. 1 and 2, a liquid crystal panel 3 having liquid crystal injected therein is provided.
The adhesive is applied under pressure, and then the pressure is reduced and the adhesive is drawn into the injection hole.

Further, in the liquid crystal adhesive coating device shown in FIGS. 3 and 4, the liquid crystal panel 3 is formed by injecting liquid crystal therein.
Is applied at room temperature, and after cooling, the adhesive is drawn into the injection hole.

When the liquid crystal panel is conveyed to a predetermined position by the above-mentioned liquid crystal adhesive applying device, the adhesive storage receiver 5 rises and the transfer pin 6 rotates to remove the adhesive in the adhesive storage receiver. After the attachment, the transfer pin is moved to the injection hole of the liquid crystal panel and the adhesive is applied to the injection hole of the liquid crystal panel.

[0013]

As described above, according to the present invention, when the liquid crystal panel is conveyed to a predetermined position, the transfer pin rotates and adheres the adhesive in the adhesive receiving container, and the transfer pin is attached to the liquid crystal panel. Since it is configured to move to the injection hole and apply the adhesive to the injection hole of the liquid crystal panel, there is a unique effect that the injection holes of many liquid crystal panels can be closed at one time. Also, since the injection holes of many liquid crystal panels can be closed at once,
Unlike the conventional structure, there is a unique effect that the adhesive can be surely applied to a large number of liquid crystal panels without the liquid crystal dripping.
