[Abstract]:China's photovoltaic industry has a great potential for development, and the demand for photovoltaic products is increasing. As a core component of photovoltaic power generation, the level of packaging laminated equipment technology has an extremely important impact on the development of the entire industry. The key equipment and core technology of solar cell module manufacture are also grasped by foreign countries. This paper focuses on improving the production efficiency of solar cell module and reducing the exhaust gas emission in production. In this paper, the design and research of the large-scale solar cell module laminating press are carried out, such as raising the temperature control precision and the temperature uniformity level. The main contents are as follows: using the vacuum hot pressing method, a kind of feeding system and preheating system are designed. The overall scheme of solar cell assembly laminating press composed of laminating system, heat preservation system and discharging system is proposed, and the performance index requirements and specific structure design requirements of the whole machine are drawn up, and the preheating system of solar cell module laminating press is designed. The heating system, the insulation system and the exhaust gas collection system are designed. At the same time, a four-cylinder synchronous hydraulic system is designed for the upper box movement of the laminating press to ensure that the upper box motion is always parallel to the heating platform during the opening of the cover. On the basis of ANSYS software, the three-dimensional geometric model and finite element analysis of the upper and lower vacuum chamber are carried out, and the steady-state temperature field analysis model of the heating system is established. The heating scheme of bidirectional temperature control is designed and compared with that of unidirectional temperature control. Based on SOLSH190 laminated element, a three-dimensional contact finite element model of silicon rubber plate-battery assembly is established. The superelasticity of silicone rubber and the anisotropy of aramid fabric are considered in the model. With the help of the APDL language of ANSYS software, the program of analysis and calculation is compiled, and the contact state of the silicone plate assembly is grasped, which ensures the uniform force of the assembly.
