Description

Technical Field

[0001] The utility model relates to the technical field of glasses processing equipment, and more specifically, to a glasses height scriber. Background Art

[0002] Currently, when people go to an optical shop to buy glasses, they need to choose a frame first. The frame is installed with a lining. The processing master draws a horizontal line on the lining, places the lining with the horizontal line on the dial of the template punching machine, and aligns it with the scale before punching. The punched holes are used to position the lining and fix it on the edge grinder. The processing master installs the punched lining on the edge grinder, and puts the unprocessed lens on the other side. The edge grinder processes the lens according to the shape of the lining until the two have the same shape. The processed lens is installed back on the frame, and the above operations are repeated to complete the processing of the lens on the other side.

[0003] In the above process, there is a critical step, which is the step of drawing horizontal lines. Currently, it is done by experienced craftsmen who draw the lines manually, and the standard is not high enough. If the lines are not drawn horizontally, the punching position will be skewed, and errors will occur in the processing of the lens, which will ultimately affect the lens effect.
