Embodiment Construction

[0025] Reference will now be made in more detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers have been used throughout the drawings for the same or like parts.

[0026] image 3 is a front view showing the structure of the FFL upper plate production system according to the present invention. As shown, the system according to the present invention includes a conveying unit 70 for real-time conveying the glass panel G and the FFL upper plate L in a desired direction. The conveyor unit 70 is configured as follows: a plurality of conveyors 71 of the same length are arranged in the conveyor unit 70, so that the conveyors 71 form a multi-layer conveyor structure, including an upper conveyor 71a and a lower conveyor 71b. The conveying unit 70 of the present invention having a multilayer conveyer structure can be implemented in the following different ways. Such as Fig...

Abstract

A system for producing upper plates of flat fluorescent lamps (FFL upper plates) is disclosed. In the system, various units used for producing the FFL upper plates are placed on or around multi-storied conveyors of a conveying unit, so that the area and space required to situate the various units is minimized. The system also allows an FFL upper plate producing process, including glass panel feeding, glass panel heating, glass panel shaping to provide an FFL upper plate, FFL upper plate heat-treatment, and FFL upper plate discharge, to be executed quickly and continuously in real time, thus maximizing work efficiency and productivity when producing the FFL upper plates. The system includes a conveying unit having a plurality of conveyors placed to form a multi-storied conveyor structure, first and second transfer units placed at opposite ends of the conveying unit, a glass panel feed unit to feed glass panels onto the conveying unit, a heating unit to further heat the glass panels on the conveying unit, a shaping unit to shape the heated glass panels, thus providing FFL upper plates, a heat treatment unit to slowly cool the FFL upper plates, and a product discharge unit to discharge the FFL upper plates from the conveying unit to the outside of the system.

Description

technical field [0001] The present invention generally relates to a production system for an upper plate of a flat fluorescent lamp (Flat Fluorescent Lamps; FFL) used for a backlight unit in a display device such as a liquid crystal display, and in particular to an upper plate (FFL upper plate) for a flat fluorescent lamp. plate) production system in which various units for producing FFL upper plates are distributed on or around a multi-layer conveyor of a conveying unit, thereby minimizing the area and space requirements for placing various units, And make the FFL upper plate production process including glass panel supply, glass panel heating, glass panel forming for FFL upper plate, FFL upper plate heat treatment, and FFL upper plate unloading and other steps to be carried out in real time, quickly and continuously, so as to maximize Improve work efficiency and productivity in the production of FFL boards. Background technique [0002] Generally, a flat fluorescent lamp ...
