Crack detection device and method for preventing secondary damage and used for touch screen failure detection

Abstract

The invention discloses a crack detection device and a crack detection method for preventing secondary damage for touch screen failure detection, belongs to the technical field of touch screens, and aims to solve the problem that the touch screen is easily subjected to secondary damage due to the fact that small particles and other impurities are not removed on the screen after the touch screen is fed into the detection device when the touch screen is detected. The device comprises a mounting base and a detection assembly fixedly mounted at one end of the top surface of the mounting base, a conveying belt is arranged in an inner cavity in the lower end of the middle of the mounting base, a film pasting cutting assembly is arranged in the middle of the mounting base, and a film feeding assembly is arranged in the middle of the inner cavity of the mounting base; according to the touch screen film pasting device, when film pasting and follow-up detection are carried out on a touch screen, the touch screen cannot be damaged due to the fact that impurities exist on the surface of the touch screen, automatic processing is carried out in the whole process, the production efficiency is improved, and the production cost is reduced. And meanwhile, the detection safety of the touch screen is ensured.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a crack detection device and method for preventing secondary damage for failure detection of touch screens. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. Drive various connecting devices according to pre-programmed programs, which can be used to replace mechanical button panels, and produce vivid audio-visual effects through liquid crystal display screens. [0003] A touch screen crack detector is proposed in the document CN111948227B, the detector includes a clamping device, a lifting device, a detection device, a support device, a transport device and a controller, the clamping device is configured to move the touch screen; the support device is constructed In order to support the touch screen and cooperate with the detection device ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a crack detection device and method for preventing secondary damage for touch screen failure detection. The device is used to work, thereby solving the problem of using the crack detection device to detect the touch screen after it fails in the above background. After the touch screen is sent into the detection device, the touch screen is prone to secondary damage due to the small particles and other debris that are not removed on the screen, and the detection structure in it is also prone to secondary damage to the touch screen during the close detection process , it is not only dangerous to use, but also easy to increase cost loss and inconvenient to use
