The amorphous silicon battery assembly is normally made by plating silicon, NI-G (or other element is in modes such as depositions) technology, is made up of main film body battery, EVA glue, back-panel glass (or other material).Thereby in existing technology packaging technology, coated glass, back-panel glass layer glass directly enter the temperature (about 120-150 ℃) that laminating apparatus is set by room temperature, like this, will make assembly temperature raise, form the big temperature difference suddenly, glass easily produces distortion, and, because of layer glass is subjected to the influence distortion of the temperature difference different, causes and vacuumize weak effect, easily make assembly produce bubble, directly have influence on product quality.
Summary of the invention
In view of existing technology status, the purpose of this utility model is to provide pre-heating device before a kind of amorphous silicon membrane lamination, and it has by the assembly to be pressed that enters before the lamination chamber is carried out preheating, with the temperature difference after reducing it and entering the lamination chamber, reduce distortion, finished the utility model on this basis.
For achieving the above object, pre-heating device before the amorphous silicon membrane lamination that the utility model provides, comprise conveyer belt top and be positioned at the conveyer belt bottom heating plate and following to hot plate is installed, cover heating plate and with distributing on the hot plate temperature sensor and heater are set down; Wherein be distributed with temperature sensor on heating plate and the following heating plate on described and be connected with temperature controller, this temperature controller is connected to the PLC controller.Make the temperature of heating plate and play heating plate on it realize regulating by temperature control system and set, control, temperature controlling range is controlled in the temperature range of EVA material, avoids EVA to melt, and can not influence product quality, reaches pre-heat effect.
According to above-mentioned application characteristic, the described temperature controlling range that goes up heating plate and following heating plate is 40-80 ℃.Like this, the EVA material is melted, can guarantee the quality of product again.
Last heating plate and following heating plate related in above-mentioned are to adopt oily heating, electrical heating, oily electric Hybrid Heating or adopt the hot blast mode of heating.The selection of several modes will be selected for use according to the working site condition.
But employed temperature controller adopts fixedly temperature controller or temperature controller in above-mentioned.
Temperature controller is selected Omron E5 series for use; The KT of Panasonic series; Shanghai TTM series.
In a word, pre-heating device before the amorphous silicon membrane lamination that the utility model provides, by utilizing the temperature controller control temperature setting of heating plate up and down, realization is heated in advance to the assembly to be pressed that enters before the lamination chamber, in order to the temperature difference after reducing it and entering the lamination chamber, reduce the distortion of layer glass, this is to implement key of the present utility model.
