Description
技术领域technical field
本发明涉及光伏组件制造技术领域，具体为一种在线纸护角自动识别方法。The invention relates to the technical field of photovoltaic module manufacturing, in particular to an online paper corner automatic identification method.
背景技术Background technique
光伏组件(也叫太阳能电池板)是太阳能发电系统中的核心部分，也是太阳能发电系统中最重要的部分。其作用是将太阳能转化为电能，并送往蓄电池中存储起来，或推动负载工作；但是，随着微型逆变器的使用，可以直接把光伏组件的电流源转化成为40V左右的电压源，就可以驱动电器应用我们的生活当中；同时，光伏组件在不断创新，由于光伏组件在业内来讲叫做中国制造，应该有中国创造，进而出现光伏组件的升级创新产品，如光伏陶瓷瓦，光伏彩钢瓦，这类产品可以直接代替传统建材瓦片，还有了光伏组件的功能，一旦步入通用市场，将对光伏组件和传统建材造成一定冲击。Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy, and send it to the storage battery for storage, or to drive the load to work; however, with the use of the micro-inverter, the current source of the photovoltaic module can be directly converted into a voltage source of about 40V. It can drive electrical appliances in our life; at the same time, photovoltaic modules are constantly innovating. Since photovoltaic modules are called Chinese manufacturing in the industry, they should be created in China, and then there are upgraded and innovative products of photovoltaic modules, such as photovoltaic ceramic tiles and photovoltaic color steel. Tile, this kind of product can directly replace traditional building material tiles, and also has the function of photovoltaic modules. Once it enters the general market, it will have a certain impact on photovoltaic modules and traditional building materials.
目前为提高光伏组件制造效率，各大厂商均在提高制造自动化，其中自动分档已进入各个制造车间，极大的减少了员工的作业强度，但是，在自动分档后，若发现有组件缺失纸护角（纸护角可实现对组件角部保护作用，亦可将堆叠的相邻组件隔离，避免边框紧挨划伤），则需进行返工安装纸护角，如此耗时耗力，而且易发生组件磕碰现象，影响组件质量，纸护角检查存在滞后性，当在分档工位发现某块组件缺失纸护角后，或许该块组件上已堆叠多块组件，返工时需人工将已堆叠组件全部抬掉，方可对该块组件加装纸护角，返工强度大，用时长，浪费人力，降低制造效率；因此特开发一种在线纸护角自动识别方法，以实现在分档之前及时检查是否存在纸护角缺失现象，及时发现及时补装，从而可避免分档后的返工作业，省时省力，提高作业效率。At present, in order to improve the manufacturing efficiency of photovoltaic modules, major manufacturers are improving manufacturing automation. Among them, automatic binning has entered each manufacturing workshop, which greatly reduces the work intensity of employees. However, after automatic binning, if any components are found to be missing Paper corner protectors (paper corner protectors can protect the corners of the components, and can also isolate stacked adjacent components to avoid scratches on the frame), it is necessary to rework and install the paper corner protectors, which is time-consuming and labor-intensive, and Component knocking is prone to occur, which affects the quality of components. There is a lag in paper corner inspection. When a module is found to be missing paper corners at the binning station, it may be that multiple components have been stacked on this module. Only when all the stacked components are removed can paper corners be added to the component, the rework is intensive, time-consuming, wastes manpower, and reduces manufacturing efficiency; therefore, an online paper corner automatic identification method is specially developed to realize Before filing, check whether there is any missing corner of the paper, and find out and reinstall it in time, so as to avoid rework after filing, save time and effort, and improve work efficiency.
