摘要 隨著科學技術(shù)的進步和用工成本的提高，越來越多的生產(chǎn)流水線開始采用自動化裝置代替人工進行單調(diào)、頻繁和重復的長時間作業(yè)，或是危險、惡劣環(huán)境下的作業(yè)。樹脂鏡片分揀裝置用在鏡片疵瑕檢測生產(chǎn)線上，其功能是代替人工完成生產(chǎn)線上樹脂鏡片的搬運與分揀作業(yè)。本課題對樹脂鏡片分揀裝置的應用進行了研究，針對該裝置產(chǎn)生的實際背景和將來的實際用途，其研究目的和意義如下：（1）該樹脂鏡片分揀裝置采用光學顯微鏡，對樹脂鏡片瑕疵進行四百倍放大，測量了疵病的尺寸，用CCD拍攝圖像代替了肉眼觀察瑕疵。既避免了肉眼觀察瑕疵產(chǎn)生的疏漏和視力的有限性，又避免了工人視覺疲勞和增加了樹脂鏡片分揀、分級的精度。（2）自動分揀技術(shù)代替人工分揀，減少了勞動強度，提高了工作效率。通過圖像處理設備，使得鏡片自動分級，實現(xiàn)分揀效率：2只/秒。確保精確地釋放到下料機構(gòu)，方便快捷。其實驗方法是通過CCD拍攝圖像，并對樹脂鏡片瑕疵進行放大。由于使用雙攝像頭，所以為確保圖片的完整，拍攝后將拍攝圖像合成為一張圖像。對樹脂鏡片進行精確分級的分揀的裝置為三盤式分揀裝置，主體由上蓋，中盤，下蓋組成。中盤的旋轉(zhuǎn)精度由凸輪分割器保證。傳動部分是由Y90S-4三相異步電動機輸出動力，通過減速器將動力傳遞給中盤的主軸，進而實現(xiàn)中盤的旋轉(zhuǎn)，被分級鏡片精確地投放在下料結(jié)構(gòu)上，輸送到精確的位置。

Resin lens sorting device design
Abstract With the progress of science and technology and labor costs rise, more and more production line start with automatic device instead of artificial drab, frequent and repetitive job for a long time, or danger, the exercise of harsh environments.Resin lens sorting device used in lens testing on the production line, its function is to replace artificial to complete production line of resin lens handling and sorting operation.This topic to the application of the resin lens sorting device are studied, according to the actual background of the devices and the actual use of in the future, the research purpose and meaning is as follows: (1) the resin lens sorting device by optical microscope, to four hundred times magnification of resin lens defects, measure the size of the fault, using the CCD photograph images instead of the naked eye defects.Avoids macroscopic observation defects produced by defects and limited vision, visual fatigue and avoid the workers and increasing the resin lens sorting, the accuracy of classification.(2) the automatic sorting technology instead of manual sorting, reduced the labor intensity, improve work efficiency.Through image processing equipment, makes the lens automatic grading and implement sorting efficiency: only 2 per second.Released into the blanking mechanism to ensure accurate, convenient and quick.The experimental method was shot by CCD image and enlarge resin lens defects.Due to the use of dual cameras, so as to ensure the integrity of images, taken after the synthesize shooting images into an image.Accurate classification of resin lens sorting device for three disc sorting device, main body by the cover, the central disk, under cover.The rotation of the central disk by CAM division to ensure accuracy, rotating 60 degrees at a time.Transmission part is the rated power is 1.1 KW, rated torque and maximum torque of 2.2 N.m m, full speed to 1400 r/min Y90S - 4 three-phase asynchronous motor, through the transmission ratio is 1:6 0 transfer power to the main shaft of reducer, thus achieve the rotation of the central disk,By classifying the lens precisely on the next material structure, to the exact location.
