Description

The present invention relates to a solar cell panel for photovoltaic power generation and an electronic panel (liquid crystal plate / organic EL plate) for TV image display / PR image display (electronic signboard plate).
More specifically, this type of solar cell panel / electronic panel is a multilayer plate product in which a light receiving element plate / light emitting element plate is sandwiched between multilayer plates. The present invention relates to a method of applying a sealant to the peripheral portion of the multilayer plate product and an edge seal structure of the multilayer plate product.

In a multilayer flat plate product such as a solar battery panel, as a known technique for preventing moisture intrusion on a mating surface, Japanese Patent Application Laid-Open Publication No. 2003-103214, “Painting Method for Sealing Agent”, discloses two sheets. A step portion is formed at an edge portion of the flat plate, and a sealing agent is applied to the step portion from a nozzle of a coating device.

Japanese Patent Laid-Open No. 2003-103214

  In the above known technique, a step portion is formed on the edge of two flat plates A, and a sealing agent is applied to the step portion from a nozzle of a coating device. In the known multi-layer product edge seal structure, since the beat-like sealant is dropped and applied only to the stepped portion, there is a problem that measures to prevent moisture intrusion on the mating surfaces are uncertain.

As a general seal structure using packing, an annular groove is formed on the mating surface, an annular rubber packing having a shape corresponding to the annular groove is manufactured, and an annular rubber packing is inserted into the annular groove, and then aligned. An annular rubber packing seal structure is conceivable that prevents the intrusion of moisture on the mating surfaces by pressing and fixing the surfaces from above.
In the seal structure using the packing, it is not possible to expect reliable measures to prevent moisture intrusion, and it is necessary to select an annular rubber packing that matches the annular groove, to set the annular rubber packing, to fix the mating surface, and to work in multiple stages. There are drawbacks.

Therefore, the present invention reliably prevents moisture from entering the storage area (matching surface) of the electronic plate, which is the main part, in the multilayer plate product A such as a solar cell panel or an electronic panel. In addition, the sealing structure as a countermeasure against moisture intrusion on the storage area (joint surface) of the electronic plate is a single operation of applying a sealing agent to the periphery of the multi-layer flat plate product, thereby reducing the cost by improving the efficiency of the manufacturing operation.
