Embodiment Construction

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] figure 1 It shows the steps flow of a method for measuring the curvature of the glass film of the touch screen proposed by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0024] A method for measuring the curvature of a glass film on a touch screen, the method for measuring the curvature comprises the following steps:

[0025] S101. Carry out film projection on the radian of the standard design, and generate the first arc;

[0026] S102. Enlarge and ...

Abstract

The invention belongs to the technical field of radian measurement, and provides a touch screen glass membrane radian measurement method and system. The radian measurement method comprises the following steps that A. film projection is performed on the standard designed radian, and a first arc is generated; B. the radian cross section of a touch screen glass membrane is amplified and projected to a projector, and a second arc is generated; C. alignment and correction are performed on the first arc and the second arc, and the radian difference of the first arc and the second arc is calculated; and D. whether the radian of the touch screen glass membrane meets the requirements is judged according to the radian difference of the first arc and the second arc. With application of the radian measurement method, whether the radian of the touch screen glass membrane meets the requirements is judged according to the radian difference of the first arc and the second arc; and whether the second arc deviates relative to the first arc is directly seen with the naked eyes so that whether the radian of the touch screen glass membrane meets the requirements can be further verified, and the effect of accurately measuring the radian of the touch screen glass membrane can be realized.

Description

technical field [0001] The invention belongs to the technical field of radian measurement, and in particular relates to a method and system for measuring a radian of a glass film of a touch screen. Background technique [0002] At present, more and more people use smart phones, so it is very important to design the curvature of the glass film (CoverLens) on the touch screen of the mobile phone, and its curvature design directly affects the experience of customers. [0003] In order to solve the problem of measuring and monitoring the touch screen glass film in the production process and incoming materials, a two-dimensional measuring instrument is usually used to roughly measure the edge curvature of the touch screen glass film with a model of 2.5D or 3D, but it has the following problems: [0004] 1. The curved surface of the touch screen glass film is a smooth transition, and the two-dimensional measuring instrument cannot accurately capture the starting point and ending p...
