Problems solved by technology
At present, manual positioning and placement require operators to calibrate repeatedly, which not only reduces the installation efficiency, but also is prone to deviation, which is not conducive to the yield of the lens
Moreover, in the prior art, the spectacle lens after milling is removed from the trimming equipment, and then the grinding wheel is used to grind the positioning gap. In this operation mode, due to the secondary positioning of the spectacle lens, it is easy to cause deviations in the positioning of the polarizing line direction , which is not conducive to the yield of the lens

The invention discloses a spectacle lens trimming device. According to the technical scheme, the spectacle lens trimming device is characterized in that a rack, a fixed device, an edge cutting device and a milling device are included; the fixed device comprises a fixed base, a movable seat and a first driver, and the first driver can clamp and fix a spectacle lens between the movable seat and the fixed seat in the process of driving the movable seat to be close to the fixed seat; the edge cutting device comprises an edge cutting tool, a second driver and a third driver, and the second driver drives the edge cutting tool to mill the periphery of the spectacle lens when the third driver drives the spectacle lens to rotate; the milling device comprises a milling tool, a fourth driver and a fifth driver, and the fifth driver mills out a locating gap in the process of driving the milling tool to be close to the spectacle lens; the trimming device further comprises a handheld clamp and a locating assembly, and the handheld clamp comprises a base, a clamping handle and an elastic assembly; and the locating assembly comprises a locating block and a limiting block. By means of the device, the demounting and mounting efficiency and the machining yield of the spectacle lenses can be increased easily.
Description
technical field [0001] The invention relates to the technical field of spectacle lens processing, more specifically, it relates to a spectacle lens trimming device. Background technique [0002] The surface optical processing has been completed, and the lens that has not been edged according to the size and geometry of the frame is called a raw edge spectacle lens, especially the film that is attached to the lens by adding a polarizing effect on the lens. After the film processing is completed, it will be on the lens. Residue is left around the perimeter of the lens, affecting the appearance of the finished lens. [0003] At present, the residue left on the periphery of the lens after filming will be eliminated by milling. The trimming equipment mainly includes a device for clamping the spectacle lens and a device for machining the spectacle lens. [0004] However, since the lens is also provided with a positioning notch for determining the direction of the polarizing line,...
