Description

Silica gel button pressure test equipment

Technical Field

The utility model relates to a silica gel button production technical field, concretely relates to silica gel button pressure test equipment.

Background

The thin film keyboard mainly comprises a keycap, scissor feet (an X-shaped support) arranged below the keycap and a silica gel key, wherein the X-shaped support is used for fixing and stabilizing the keycap and is matched with a thin film circuit layer (namely a flexible circuit board) arranged at the bottom; wherein, the silica gel button is the back-off bowl form, and its bowl mouth portion is installed on the thin film circuit layer, and protruding being used for contacting the key cap at the bottom of its bowl, its inside has connects bellied axle core. When the key cap is pressed, the silica gel key is driven by the key cap and is triggered downwards, so that the electrode contact points in the shaft core driving thin film circuit layer in the silica gel key are contacted with each other to realize conduction, and the key cap is reset through the elasticity of the silica gel key. The thin film keyboard adopts a structure that scissor feet are matched with the silica gel keys and is matched with the light thin film circuit layer, so that the thin film keyboard has the advantages of light weight, thinness and low cost.

Because the silica gel button is pasted on the flexible circuit board and the circuit board is conducted by pressing downwards, the conduction force is the pressing force of the silica gel button, and the silica gel button and the flexible circuit board are pasted to have the phenomena of hardness and heavy pressing, and the silica gel button needs larger force than the normal button pressing. Because the pressing force of the silica gel key changes before and after the silica gel key is pasted, the silica gel key and the flexible circuit board are pasted into a finished product and then are manually pressed for testing, so that the testing method is low in efficiency and wastes working hours and cost.
