Description
Technical Field
The invention relates to the technical field of photovoltaic cell detection, in particular to mirror detection equipment for photovoltaic cell assembly production.
Background
Solar photovoltaic cells (photovoltaic cells for short) are used to directly convert the light energy of the sun into electrical energy. Silicon solar cells using silicon as a substrate are widely used in the conventional ground photovoltaic systems, and can be classified into monocrystalline silicon, polycrystalline silicon and amorphous silicon solar cells. Monocrystalline silicon and polycrystalline silicon batteries are superior to amorphous silicon batteries in terms of overall performance such as energy conversion efficiency and service life. Polycrystalline silicon is less efficient than monocrystalline silicon in conversion but cheaper. According to the application requirement, the solar battery is combined to reach a group of photovoltaic cells with certain rated output power and output voltage, namely a photovoltaic module. According to the size and scale of the photovoltaic power station, various arrays with different sizes can be formed by the photovoltaic modules. The photovoltaic module is manufactured by adopting high-efficiency monocrystalline silicon or polycrystalline silicon photovoltaic cells, high-light-transmittance toughened glass, tedlar, corrosion-resistant aluminum multi-frame and other materials and adopting an advanced vacuum lamination process and a pulse welding process. A long service life can be ensured even in the most severe environments. Solar cells are devices that directly convert light energy into electrical energy through a photoelectric effect or a photochemical effect. Thin film solar cells operating on the photoelectric effect are the main stream, while solar cells operating on the photochemical effect principle are still in the germination stage. The solar light irradiates the semiconductor p-n junction to form a new hole-electron pair. Under the action of the electric field of the p-n junction, holes flow from the n region to the p region, electrons flow from the p region to the n region, and current is formed after the circuit is turned on. The solar photovoltaic module production and manufacturing process mainly comprises the steps of tightly packaging single solar cell slices after series connection and parallel connection so as to protect the surface electrodes, interconnecting wires and the like of the cell slices from corrosion, and the packaging also avoids the fragmentation of the cell slices, so that the solar cell module production process is exactly the packaging process of the module.
In the production process of the photovoltaic cell assembly, in order to ensure the quality and photoelectric conversion efficiency of the photovoltaic cell assembly, the surface of the photovoltaic cell assembly needs to be detected, the detection process generally comprises surface detection and functional detection, wherein the surface detection of the photovoltaic cell assembly mainly aims at detecting defects on the surface of the photovoltaic cell assembly, observing whether the surface of the photovoltaic cell assembly is smooth or not, whether the surface of the photovoltaic cell assembly is worn or not and is a complete mirror surface or not, and preventing the photoelectric conversion efficiency from being reduced due to uneven surface of the photovoltaic cell assembly.
In order to detect defects on the surface of the photovoltaic cell assembly, manual detection is mostly used, a large number of defective photovoltaic cell assemblies can be found by the detection mode, but in order to ensure that the detection cannot be interfered by external environment light, the detection environment is generally darkly in a dark room in a relative sense, and eyes observe the photovoltaic assembly with higher brightness in the dark room environment for a long time, so that eye fatigue is caused, and at the moment, the detection precision is reduced, and the actual quality is influenced.
The photovoltaic cell assembly generally can light the surface of the photovoltaic cell assembly when defect degree detection is carried out, but because the photovoltaic cell assembly has no built-in light source, the photovoltaic cell assembly is generally lighted in an auxiliary mode by using an external light source, but a limiting device is not arranged in the lighting process to effectively fix the photovoltaic cell assembly, and the surface of the photovoltaic cell assembly is lighted unevenly due to lower peripheral brightness of the light source assembly, so that the detection judging process is influenced.
