Description

Jig for manufacturing solar cell module The present invention relates to a jig for manufacturing a solar cell module. Generally, a solar cell module is formed by bonding a front glass plate, an encapsulant (e.g., EVA resin), a solar cell, an encapsulant, and a resin-based backsheet, so that power generation occurs on one side of the module. Meanwhile, there are also glass-to-glass type solar cell modules designed to improve durability and allow both sides of the solar cell module to contribute to power generation. A glass-to-glass type solar cell module is formed by bonding a first glass plate, an encapsulant, a solar cell, an encapsulant, and a second glass plate. The lamination process of a solar cell module involves stacking the constituent elements of the module in sequence and then fixing them through an encapsulant by compressing them using a laminating device under high temperature and vacuum. In the lamination process, the solar cell module is pressed using a flat diaphragm sheet made of an elastic material such as silicone. At this time, the corner edges of the solar cell module may be additionally pressed due to excessive pressure applied by the sagging of the diaphragm sheet. This causes non-uniformity in the thickness of the solar cell module, making it difficult to fasten the fixing frame for securing the solar cell module. In addition, in the case of a glass-to-glass module, a hole for electrode wiring is machined in the rear glass and the location is sealed with Mini-Glass. However, since this part may protrude more than the rear glass, if it comes into contact with the diaphragm sheet, the Mini-Glass may break due to pressure unevenness.

The present invention is capable of various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various forms. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted. In the following embodiments, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another component. In the following examples, singular expressions include plural expressions unless the context clearly indicates otherwise. In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added. In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, so the present invention is not necessarily limited to what is illustrated. Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described.
