Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings. figure 1 It is a schematic diagram of the structure of pasting the reflective film on the photovoltaic ribbon of the present invention. First, the reflective film 2 is cut out to be the same as the photovoltaic ribbon 3, and then the pressure block 1 is used to apply a certain pressure to the reflective film 2. Using the pressure and the reflective film 2 The adhesive force on the reverse side will stick the reflective film 2 on the surface of the photovoltaic ribbon 3.
[0025] Such as figure 2 As shown, it is a schematic diagram of the optical path of the present invention, with figure 2 In the process, the incident light directly enters the glass 6 of the photovoltaic cell panel, and irradiates the reflective film 2. By using the refraction function of the reflective film 2 and the single-sided light transmittance of the glass 6, the light that cannot generate elec...

The invention discloses a sticking method for a reflective film for a photovoltaic module in the photovoltaic welding strip automatic welding production line. The reflective film with the light reflective function is stuck to a photovoltaic welding strip. The sticking method comprises the following steps that a corresponding reflective film roll is selected, and installed on idler wheels of a reflective film wiring mechanism; the end of the reflective film roll is led out to be installed on a pressing block of a reflective film sticking mechanism; the reflective film sticking mechanism is aligned to the end of the photovoltaic welding strip, and the pressing block of the reflective film sticking mechanism is pressed downwards to press and connect the reflective film to the upper surface at the end of the photovoltaic welding strip; the reflective film wiring mechanism and the reflective film sticking mechanism synchronously move towards the tail of the photovoltaic welding strip from the end of the photovoltaic welding strip, and synchronously press and connect the reflective film to the upper surface of the photovoltaic welding strip. According to the sticking method for the reflective film for the photovoltaic module in the photovoltaic welding strip automatic welding production line, the light reflective function of the reflective film is utilized for reflecting the light on the surface of the photovoltaic welding strip to the portion, capable of generating electricity, on the surface of a photovoltaic panel, and therefore photoelectric converting efficiency is improved.
Description
technical field [0001] The invention relates to a production process of photovoltaic power generation battery panel components, in particular to a method for attaching reflective films for photovoltaic modules in a photovoltaic ribbon automatic welding production line. Background technique [0002] Solar photovoltaic power generation system (referred to as photovoltaic) is a system that uses the photovoltaic effect to directly convert sunlight energy into electrical energy. The main component of its photoelectric conversion is a semiconductor crystalline silicon photovoltaic cell. When the sun shines on the crystalline silicon photovoltaic cell , the crystalline silicon photovoltaic cell will convert the sun's light energy into electrical energy and generate electric current. When many crystalline silicon photovoltaic cells are connected in series or in parallel, they can become solar panels with relatively large output power. At present, in the production of photovoltaic m...
