[0002] Curved glass screen is a common part, which is widely used in the field of mobile phones, computers and other electronic products. After the processing of curved glass screen is completed, it needs to be measured. The main data measured are the length, the radian of the outer arc surface and the inner arc. The radian of the surface, most of the existing measurements are made by manual measurement tools for more conventional detection, and most of the radians are measured with a radian ruler. Using the existing method for measurement, it is impossible to achieve all-round measurement, resulting in Inaccurate measurements

Abstract

The invention relates to a curved glass screen size measuring method. The method comprises the following steps: 1) attaching one end of a to-be-measured product to an interception block; 2) descendinga length measurement lifting block which has a specific distance with the interception block, judging whether a length is qualified or not through whether a length measurement contact induction screen in an inner side of the length measurement lifting block generates an induction signal, and judging whether a thickness is qualified or not according to an induction signal generation area; 3) for aqualified product detected in the step (2), descending an outer arc measurement lifting block and sleeving an outer arc of the product, and determining whether the outer arc is completely qualified through the area, where an outer arc measurement contact induction screen, consistent with a theoretical shape of the outer arc of the product, of the inner side of the outer arc measurement lifting block generates the induction signal; and 4) placing the qualified product detected in the step (3) on an inner arc measuring arc block, and judging whether the inner arc of the product is completely qualified or not through the area, where an inner arc measuring contact induction screen arranged on the outer side of the inner arc measuring arc block generates the induction signal.
