The core mechanism in the laminating machine is the laminating mechanism, and the laminating machine mechanism is a main component part of a platform and a vacuum cavity of the laminating machine. The working temperature required by the laminating mechanism is about 140-160 ℃, the heating mode of the laminating mechanism of the mainstream laminating machine in the market at present mainly comprises the steps of heating the intermediate medium, namely the heat conduction oil, through an electric heating boiler, and circulating the heat conduction oil in the inner loop of the laminating mechanism of the laminating machine through an oil pump, so that the laminating mechanism of the laminating machine obtains a stable heat source to meet the process requirements. In order to reduce the cost of the photovoltaic module, it is a primary task to first consider reducing the cost in the manufacturing process and how to reduce the energy consumption of the lamination mechanism of the laminator. In addition, as the size of the assembly increases and the beat increases, the size of the single heating plate is required to be increased sharply, and the processing difficulty is increased. The novel electric heating laminating machine is a great trend of development of the photovoltaic industry, and the electric heating unit is one of core units of the electric heating laminating machine.
Currently, heating elements used in the market mainly include heating rods, microcrystalline plates, heating blankets, mica electric heating plates, and the like. The current common installation mode of the electric heating element is mainly directly fixed by screws. However, due to the difference of thermal expansion coefficients between the electric heating element and the heating plate of the laminating machine, deformation difference can be generated after temperature rise in a conventional installation mode, so that the electric heating element and the heating plate are not tightly attached, and uneven temperature is caused. Even directly, in the case of severe deformation differences, damage to the electrical heating element occurs. Based on the above, the utility model provides a novel electric heating element mounting structure.
