Problems solved by technology

However, since the edge of the full screen has a certain curvature, its production is more difficult than the production of ordinary flat screens. If the curvature of the curved screen does not match the curvature of the mobile phone frame, the produced mobile phone will whitening may occur
However, the general full-screen detection device cannot detect the edge position of the curved surface of the screen, which makes the whitening of the mobile phone equipment serious after production, and the yield rate is low.

Embodiment 1

[0037]In this embodiment, the arc surface edge detecting device of the full screen can be detected by the device to detect an arc of the arc of the full screen, thereby known a genus size of the arc edge position of the full screen.

[0038]Such asFigure 1 ~ 2 As shown, the detecting apparatus of the present embodiment includes a casing 1, the length of the outer casing 1 can be larger than the transverse width of the full screen, and the sliding block 2 can be utilized to the outer edge of the outer casing 1 on both sides of the outer casing 1. Testing; may also be set to half the width of the full screen, that is, the radians of the edge position of one side of the full screen are first detected, and the radians on the other side are detected. When the width of the outer casing 1 is half a width of the full screen, the length of one side of the outer casing 1 can be set to a fixed length, and the other side is provided with a length adjustment device to adjust the length of the end o...

Embodiment 2

[0048]This embodiment provides an arc edge detection method of a full screen, which is applied to the arc edge detection device of the full screen described above, such asFigure 4 As shown, including the following steps:

[0049]Step S1: When the pressure screen strip 4 does not contact the full screen, the end face formed by the lower end portion of all the screen strips 4 is horizontal (egfigure 2 State), the first distance between each of the screen strips 4 to its corresponding detection module 5 is detected by detecting module 5;

[0050]Step S2: Move the sliding block 2 to the arc edge position of the fully screen to be tested, and pressurize the strip strip 4 by a full screen, so that the lower end portion of all the screen strips 4 is closely contacted with the full-screen surface, at this time, The pressure screen strip 4 is moved upward along its tubular cavity 3 such that the end face formed by the upper end portion of all pieces of screen 4 corresponds to the arc of the full s...

Abstract

The invention discloses a cambered surface edge detection device and method for a full screen. The detection device comprises: a shell; a sliding block which is installed on the shell, wherein a plurality of tubular column cavities which are transversely arranged in sequence are formed in the sliding block, each tubular column cavity is internally provided with a screen pressing strip which is connected with the tubular column cavity in a sliding manner, and one end of each screen pressing strip is pressed by the full screen, so that each screen pressing strip moves along the corresponding tubular column cavity; a detection module which is arranged on the shell opposite to the end parts of the screen pressing strips and is used for detecting the distance between each screen pressing strip and the detection module, so that the moving distance of the screen pressing strips in the tubular column cavity is obtained; and a main control circuit which is arranged on the shell, is connected with the detection module, and is used for receiving the moving distance of each screen pressing strip and analyzing the moving distance to obtain the radian of the arc surface of the full screen, so that the exposure size of the screen after the full screen is mounted on the mobile phone frame shell is obtained.

Description

Technical field[0001]The present invention relates to the field of full screen detection, and more particularly to an arc surface edge detection device and a detection method of a full screen.Background technique[0002]At present, there is a common screen to act as a screen on the mobile terminal, because the edge of the full screen is curved, with a good gripping feel, deeply loved by consumers. However, since the full-screen edge position has a certain curvature, the production difficulty is larger than the production difficulty of the general planar screen, and the arc of the arc surface and the arc of the mobile phone frame are not agreed, and the produced mobile phone is in the edge position. It is possible to show a phenomenon. The general full-range screen detection device cannot detect the edge of the screen curve, so that the mobile device has been severe and the finished product is low.Inventive content[0003]In order to overcome the shortcomings of the prior art, the object...
