Description

Technical Field

[0001] The utility model relates to the technical field of keyboard conductive films, in particular to a testing device for keyboard conductive films. Background Art

[0002] Conductive film is a thin film with conductive function. The charged carriers of the conductive film are scattered by the surface and interface during the transport process. When the thickness of the film is comparable to the free path of the electrons, the influence on the surface and interface will become significant. This phenomenon is called the size effect of the film. It is equivalent to the reduction of the free path of the carriers, so the conductivity of the film is smaller than that of the bulk of the same material.

[0003] The keyboard is a device for inputting commands and data to operate computer equipment and is a frequently used tool for computer control. One of the core components of keyboard products is the conductive film, which is the main input receiving end. The conductive film generally includes a plastic circuit layer and rubber keys.

[0004] Before installing and using the keyboard conductive film, the keyboard conductive film needs to be tested to prevent the installation and use of a damaged keyboard conductive film. However, the existing keyboard conductive film testing device can only test the keyboard conductive film one by one, requiring workers to constantly add them manually, resulting in low test efficiency. Due to the characteristics of the keyboard conductive film, keyboard-type buttons are required for testing during testing, but there is currently no device for testing batches of buttons on the same conductive film at one time, resulting in low inspection efficiency and easy omissions.

[0005] Therefore, we propose a testing device for keyboard conductive film. Utility Model Content
