BACKGROUND OF THE INVENTION
The present invention relates to a transport tray for a synthetic resin plate, and is suitable for storing and transporting a plate such as a synthetic resin liquid crystal substrate and a wiring board.
[0002]
[Prior art]
Conventionally, for example, a liquid crystal substrate used in a display unit of a television, a notebook computer, a game machine, a calculator, etc., deposits an electrode or an electric conduction part on one side of a transparent glass plate, or performs sputtering. The process of carrying out etc. was performed. In order to obtain this liquid crystal substrate as a finished product, it is necessary to transport semi-finished products or products between manufacturing factories or from manufacturing factories to assembly factories in order to equip processing and electronic components that are shared in each process. was there. In this way, the transport tray for transporting the liquid crystal substrate as a semi-finished product or product is easily broken due to impact because the liquid crystal substrate is formed of a glass plate. Some semi-finished products or products were formed in a simple box shape with a larger internal dimension. And inside this box, a large number of fitting grooves for inserting both ends of the liquid crystal substrate in the longitudinal direction are provided on the inner wall so as to face each other, so that both ends of the liquid crystal substrate are inserted into the fitting grooves and the liquid crystal is inserted into the box. The base is stored to reduce the impact. By the way, recently, it is easy to procure materials, and since it is easy to mold and lightweight, a liquid crystal substrate is made of a synthetic resin plastic having transparency.
[0003]
[Problems to be solved by the invention]
When transporting a liquid crystal substrate formed of a synthetic resin plastic material, if a conventional transport tray for a liquid crystal substrate formed of a glass plate is used for transport, the synthetic resin liquid crystal substrate has flexibility. Therefore, since it is easy to bend when inserting both ends in the longitudinal direction into the fitting grooves provided on the inner wall of the box made of foamed synthetic resin, it is difficult to insert into the fitting groove. It took a lot of time and effort to operate. If the liquid crystal substrate is distorted by local tension or compression even if it is transported by interposing spacers to prevent rattling from both ends of the liquid crystal substrate stored in the fitting groove, the liquid crystal substrate However, it was easy to come into contact with each other and be easily damaged.
In addition, the liquid crystal substrate is light in weight and the surface is very soft, so if a large impact is applied from the outside, or if it is accidentally dropped and impact is applied, the product such as the liquid crystal substrate will swing in the transport tray, Since the liquid crystal substrate floats up, the surface of the liquid crystal substrate is easily damaged by friction with the transport tray. Therefore, important portions, for example, the processing portions of the electrode and the electrical conduction portion are damaged, and the yield of the product is poor.
[0004]
The present invention solves the above-mentioned conventional drawbacks, prevents the liquid crystal substrate housed in the tray body from swinging or floating in the tray body, and keeps the liquid crystal substrate in the tray body constant so as to keep friction. It is suitable for transporting without damaging the surface of the plate-like body and preventing dust from adhering to the product etc. or intrusion of moisture, thereby obtaining a product with high yield and reliability, We intend to provide a transport tray for synthetic resin plates that is small in storage space and that can be mass-produced and is inexpensive.
