Description

Gripping device for manufacturing cemented lens Technical Field The utility model relates to the technical field of lens manufacturing, in particular to a gripping device for manufacturing a cemented lens. Background The manufacturing technology of the cemented lens (also called cemented lens and compound lens) is derived from the requirements of an optical system for aberration correction and performance improvement, the development background of the cemented lens relates to the progress of optical theory, material science and precision technology, along with the development of science and technology, the requirements of people on the imaging quality of the lens are higher and higher, in order to meet the high requirements, the lens design needs to try to eliminate various aberrations affecting the imaging quality, and the chromatic aberration is the most important factor affecting the imaging quality, and in order to eliminate chromatic aberration or make chromatic aberration as small as possible, the lens must be cemented together. The traditional gluing process has obvious defects, low gluing efficiency and low production yield. Through retrieval, the patent of the utility model with the bulletin number of CN213457493U, the utility model specifically discloses an optical lens gluing device, mainly relating to the technical field of optical lens processing equipment, comprising a sliding rail, a servo motor and a bracket, wherein a sliding block in sliding connection is arranged on the sliding rail, the output end of the servo motor is connected with a screw rod through a coupler, the screw rod penetrates through the sliding block and is in threaded connection with the sliding block, a glue tank and a cylinder are respectively arranged on the bracket, a placing groove is arranged on the upper surface of the sliding block, a gluing pedestal is arranged in the placing groove, a gluing lens is arranged in the gluing pedestal, a glue inlet hose for connecting the gluing lens is arranged on the gluing pedestal, the required gluing lens is placed in the gluing pedestal, then the gluing pedestal is placed in the placing groove arranged on the upper surface of the sliding block, the servo motor is started to enable the screw rod to start rotating, then the sliding block moves on the sliding rail, glue is dripped and pressed, and the installation of the gluing lens is completed, so that the gluing precision is high, the gluing yield is improved, and a large-scale stable gluing lens assembly can be ensured.
