【摘要】：太陽能發(fā)電已經受到了全人類的關注,它的市場需求量也隨之變大。太陽能電池片的質量是影響電池片組件發(fā)電量的關鍵,所以在實際生產中對電池片的質量檢測顯得尤為重要。常見的電池片有多晶和單晶兩種,本系統主要針對多晶電池片。多晶電池片的外觀缺陷主要有缺角、邊緣破損、粗柵斷柵,以及表面顏色色差問題。多晶電池片的外觀缺陷會極大降低電池組件的發(fā)電量,并且減少其使用壽命,表面顏色色差會影響到電池組件視覺美觀,它的分類可以提高商業(yè)競爭力。本文根據電池片外觀檢測的實際需求,設計了一套基于VisionPro太陽能電池片外觀檢測系統,其集機械結構和軟件控制為一體。此系統的設計具有深刻的實際應用價值。機械結構主要包括了圖像采集系統結構、電池片分離裝置和抓取裝置。圖像采集系統的結構設計根據具體選用的相機鏡頭,光源等來確定方案,其目的是能采集到高質量的圖像,為接下來的外觀檢測提供好的基礎。電池片的分離和抓取裝置的設計根據具體電池片的擺放情況,以及電池片的特性,從而達到高效率、低碎片率的目的。它們在整個系統運輸中起到關鍵的作用。軟件控制主要包括圖像采集模塊、圖像處理模塊、通信模塊。設置相機參數,進行白平衡和標定,完成圖像采集后,利用VisionPro視覺軟件對電池片進行外觀檢測,得到所需的數據結果后,經過計算判斷,實現電池片的分類處理。最后發(fā)送命令給機械手、PLC、相機,完成通信,實現系統自動化。整個系統軟件用C#語言在Visual Studio平臺上進行編程。
[Abstract]:Solar power generation has been the concern of all mankind, its market demand has also increased. The quality of the solar cell is the key to the battery cell module, so it is very important to check the quality of the battery in the actual production. The common battery chip is polycrystalline and single crystal, this system is mainly for polycrystalline battery chip. The main appearance defects of the polycrystalline battery chip are angle, edge breakage, coarse gate broken gate, and color difference of the surface. The appearance defect of the polycrystalline battery chip will greatly reduce the battery component's power generation and its service life. The color difference of the surface will affect the visual beauty of the battery module, and its classification can improve the commercial competitiveness. In this paper, according to the actual demand of battery chip appearance detection, a solar cell appearance detection system based on VisionPro is designed, which integrates mechanical structure and software control. The design of this system has profound practical application value. The mechanical structure mainly includes image acquisition system structure, battery chip separation device and grab device. The structure design of the image acquisition system is based on the camera lens and light source to determine the scheme. The purpose of the system is to collect high quality images and provide a good basis for the next appearance detection. The design of the device for separating and grasping the battery chip is based on the placement of the battery chip and the characteristics of the battery chip so as to achieve the purpose of high efficiency and low debris rate. They play a key role in the transportation of the whole system. Software control mainly includes image acquisition module, image processing module and communication module. The camera parameters are set, the white balance and calibration are carried out, and after the image collection is completed, the appearance of the battery chip is detected by VisionPro vision software, and the required data result is obtained. After the calculation and judgment, the battery chip is classified and processed. Finally send the command to the manipulator PLC, camera, complete communication, achieve system automation. The whole system software is programmed on Visual Studio platform with C # language.
