Problems solved by technology

[0006] Straight line screen and sector screen screen methods are complex in structure and high in cost
Especially in the detection of curved screens, it is not easy to realize straight line screen and fan screen screen
[0007] Fixed-point touch screen contacts are sealed, and it is particularly difficult to control the touch force
In particular, due to the fluctuation of the air source when the touch screen is measured, the pressure of the cylinder on the screen will change, and there is a risk of damaging the screen.

Abstract

The invention discloses a screen detection device and method. The screen detection device comprises a buffer sleeve, a sliding assembly, a transmission assembly and a first spring, wherein the buffer sleeve comprises an outer wall and an inner wall which are nested, the outer wall is fixed and in clearance fit with the inner wall, and a mounting hole is formed in the middle of the inner wall; the sliding assembly is arranged in the mounting hole and in clearance fit with the mounting hole; the transmission assembly can drive the inner wall to move axially; when the first spring is configured to axially move along the inner wall, the first spring is compressed and drives the sliding assembly to move axially so as to make contact with a screen of a product. By means of the screen detection device and method, the problem that a screen of a product is damaged by an existing screen detection device exerting too much pressure on the screen of the product.

Description

technical field [0001] The present invention relates to the technical field of automatic detection, in particular, the present invention relates to a screen detection device and method. Background technique [0002] During the assembly process of smart products such as smart watches and smart phones, the screen of the product needs to be tested to determine whether the screen function is normal. The fast, convenient and safe screen detection is conducive to improving production efficiency and ensuring production quality. [0003] At present, detection methods for smart product screens are generally divided into manual detection and automatic detection. In various detection methods, since various types of screens have different requirements for force, it is necessary to protect the screen to avoid damage caused by excessive force on the screen. [0004] The manual detection method has low detection efficiency, is not stable enough, and wastes manpower. [0005] The automat...
