Description

Accurate alignment device of multilayer conductive film Technical Field The utility model relates to the technical field of conductive films, in particular to an accurate alignment device of a multilayer conductive film. Background Conductive films have a variety of definitions, commonly referred to as 'multi-layer' films for input devices such as keyboards. The keyboard conductive film is one of the core components of the film keyboard and is mainly used for triggering key signals. The circuit structure is composed of a plurality of layers of flexible films, and the upper layer circuit and the lower layer circuit are contacted by pressing to realize conduction. The keyboard conductive film is generally composed of three flexible films, namely an upper conductive film, a lower conductive film and a middle isolation layer (insulating film with hollowed-out holes). When the key is not pressed, the isolating layer blocks the upper and lower circuits, when the key is pressed, the pressure of the key cap deforms the upper layer film, the conductive circuit is contacted with the lower layer through the isolating layer hole to form a passage trigger signal, and after the key is loosened, the film is elastically restored, and the circuit is disconnected. In the production process, the upper conductive film, the middle isolation layer and the lower conductive film are required to be aligned accurately so as to ensure the stability of key signal transmission. At present, in the production process of keyboard conductive films with only small batch, the upper conductive film, the middle isolation layer and the lower conductive film are manually aligned by a worker, and manual operation depends on the experience of the worker, so that the alignment quality fluctuation is large.
