Design And Implementation Of Auto-loading Machine For Lens Blanks

As the continuous development of society and the progress of industrialization,people's demand for optical glass lens products continue to improve.The installation of optical glass lens blanks is an important process in the production of optical glass lenses.At present,the installation of the optical lens blank is completely dependent on the manual operation,so there is a problem that the plate blank is low in efficiency,the accuracy is poor and the work intensity is large.So not only a high cost of manual labor has also resulted in a huge waste of material during the subsequent finishing process.Therefore,the design and implementation of the automatic blanking machine of the lens blank can effectively improve the loading speed and loading accuracy of the lens blankIn this paper,we designed the lens blank automatic loading machine of the overall structure of the program,according to the analysis of the lens blank automatic loading of the technical requirements and loading process,also the same machine design and physical assembly of the functional modules of the machine.At the same time,we also designed the plate machine pneumatic circuit and robot automatic loading path,and successfully used them in the automatic installation of the machine.In the design of the control system of the loading machine,we applied the motion control technology of the PLC,and realized the automatic control of the loading machine through the programming of the PLC ladder program.After a deep study of the shape of the lens blank,After a deep study of the shape of the lens blank,we have adopted a visual recognition method which utilizes the camera to capture linear laser images of the lens blank,and then use the visual recognition software to process the image,based on contour matching to realize the recognition of the lens blank and output the control information to the PLC.We carried out the debugging work of structure function of the loading machine and analyzed the factors for the lens blank loading plate accuracy and recognition accuracy,and for this factor on the lens blank automatic loading experiment,which verified the function of the plate machine basic-ally reached the technical requirements of the automatic loading.And successfully completed the physical development work of the lens blank machine.The design and realization of the automatic loading machine of the lens blanks,improved the degree of automatic production of the optical glass lenses,reduced the waste of materials,saved the cost and finally will promote the development of the enterprise.
