Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] see figure 1 , the automatic centering method of the lens mainly includes the following steps: 1) preparing a standard lens; 2) debugging the automatic centering device of the lens, adjusting and measuring the distance between the objective lens of the microscope and the standard lens or the lens to be processed to meet the eccentric specification Or the measurement and calculation requirements of the centering accuracy. Here is to use the standard lens to debug the automatic centering device of the lens. When the automatic centering device for the lens is debugged, the lens to be processed is processed again; 3) the lens to be processed is prepared, and the lens to be processed is processed, so that the lens to be processed The optical axes of the upper lens and the lower lens coincide; 4) Detect the yield of the finished product.

A method for automatic lens centering, comprising the following steps: step 1, debugging an automatic lens centering device, the automatic lens centering device includes a machine base, and the machine base is provided with a fixed plate for placing a standard lens or a lens to be processed; A core tray, a through hole is arranged in the center of the center tray, a microscope is arranged under the center tray, and an electric clamp for moving and positioning the upper lens in the lens to be processed is also arranged on the base. A pen-throwing mechanism for fixing the lower lens in the lens to be processed, a computer for measuring and monitoring the center offset between the upper lens and the lower lens in the lens to be processed, and a light source for curing the lens to be processed A glue-curing light source for curing glue; the standard lens includes a standard upper lens and a standard lower lens, and the optical axes of the standard upper lens and the standard lower lens coincide. The invention has the characteristics of stable quality, effectively improving the asperity defect of the glued lens, and improving the centering efficiency of the lens.
Description
technical field [0001] The invention relates to the technical field of optical lens processing, in particular to an automatic lens centering method. Background technique [0002] As we all know, the invention and use of cemented lenses has greatly helped the elimination of chromatic aberration in various optical imaging systems. The processing difficulty of processing two or three large lenses and then gluing them is far lower than processing a single of the same shape. High-quality lenses, so the promotion of gluing technology greatly reduces the processing difficulty of the overall optical lens. In the gluing process, in addition to lens dispensing, the key process is the core setting process. Therefore, the process optimization of the core setting process is also very important for lens bonding. [0003] In the optical industry, the current cemented lens is generally made of two to three lenses, but in most cases, the cemented lens is generally two lenses. Typically, m...
