The invention provides an astigmatic lens molding detection positioning device, which belongs to the technical field of lens mold detection and comprises a rack (1) and a controller, wherein a rotating table (2) and a detection structure (3) are arranged on the rack (1), a rotary driving assembly (4) for driving the rotating table (2) to rotate and a lifting structure (5) are also arranged on therack (1), the detection structure (3) is connected with a moving device (6), the detection structure (3) comprises a detection assembly (31), and the detection assembly (31) is connected with a displacement sensor (8). The astigmatic lens molding detection positioning device can detect and position the highest point of the edge of a astigmatic lens mold, thereby being beneficial to determining theaxial position of the astigmatic lens mold and facilitating the subsequent processing of the astigmatic lens.
Description
technical field [0001] The invention belongs to the technical field of lens detection, and in particular relates to an astigmatism lens mold-making detection and positioning device. Background technique [0002] At present, resin lenses are mostly used in spectacle lenses. In the production process of resin lenses, lens molds are generally used to close the molds, and then resin materials are poured into the molded lens molds, and then cured. After molding, the molds are opened. [0003] Astigmatism lenses are spectacle lenses used to correct astigmatism. There is an astigmatism axis on the astigmatism lens. The astigmatism axis represents the axis of the lens, which is determined by the direction of the cornea with the largest curvature and the weakest refractive power. During the manufacturing process of the astigmatism lens produced by the resin, the astigmatism axis of the lens mold also needs to be determined during the mold closing process of the lens mold. [0004] I...
