Mirror surface detection equipment for photovoltaic cell module production

Abstract

The invention relates to the technical field of photovoltaic cell detection, and discloses a mirror surface detection device for photovoltaic cell module production, which comprises a detection table, a fixed seat is arranged below the detection table, mounting plates are fixedly mounted at the left and right ends of the fixed seat, and a light emitting mechanism is arranged at the top end of the detection table; and clamping mechanisms are fixedly mounted at four corners above the light-emitting mechanism. According to the mirror surface detection equipment for photovoltaic cell module production, the detection table can be driven by the rack to move, the detection table can be driven by a sliding strip to move towards the left side relative to the sliding groove at the moment, and when a half gear rotates to be not engaged with the rack any more, the reset spring can provide elastic force to drive the rack and the detection table to move leftwards; when the half gear is engaged with the rack again, the rack can be driven to move right continuously, reciprocating left-right displacement of the detection table can be achieved by repeatedly transmitting the half gear, then the surface of the detection table is detected manually, and therefore the advantage that detection is rapid is achieved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cell detection, in particular to a mirror detection device for photovoltaic cell assembly production. Background technique [0002] Solar photovoltaic cells (photovoltaic cells for short) are used to directly convert the sun's light energy into electrical energy. At present, silicon solar cells based on silicon are widely used in terrestrial photovoltaic systems, which can be divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon solar cells. In terms of comprehensive performance such as energy conversion efficiency and service life, monocrystalline silicon and polycrystalline silicon cells are superior to amorphous silicon cells. Polysilicon is less efficient than monocrystalline silicon, but it is cheaper. According to the application requirements, a group of photovoltaic cells with a certain rated output power and output voltage after a certain combination o...

Problems solved by technology

[0003] In the production process of photovoltaic cell components, in order to ensure the quality and photoelectric conversion efficiency of photovoltaic cell components, the surface of photovoltaic cell components needs to be inspected. The detection process generally includes surface inspection and functional inspection. The main purpose of the surface inspection of photovoltaic cell modules is Detect defects on the surface of photovoltaic cell components, observe whether the surface is smooth, whether there is wear and tear, and whether it is a complete mirror surface, so as to prevent the unevenness of the surface from reducing the photoelectric conversion efficiency. The current general detection method is to light up the photovoltaic motor components Furthermore, manual inspection of the surface generally includes two types of touch and observation. This detection method requires a lot of manual labor. Manually swing it and observe carefully

[0004] In order to detect defects on the surface of photovoltaic cell components, most of them are carefully inspected manually. Although this detection method can find a large number of defective photovoltaic cell components, in order to ensure that the detection will not be disturbed by external ambient light, the detection Generally, the environment is relatively dark in a dark room, and the human eye will inevitably cause eye fatigue when observing high-brightness photovoltaic modules in a dark room environment for a long time. At this time, it will lead to a decrease in detection accuracy and affect the actual quality.

[0005] Photovoltaic cell modules generally light up their surfaces when performing defect detection, but since photovoltaic cell modules do not have a built-in light source, an external light source is generally used to assist the lighting of photovoltaic cell modules, but there is no setting during the lighting process. The limit device effectively fixes the photovoltaic cell assembly, and because the surrounding brightness of the light source assembly is low, the surface of the photovoltaic cell assembly is not evenly lit, which affects the judgment process of the detection
