Manufacture of integral elastic sheet for computer keyboard

Abstract

A manufacture method of integral elastic element for computer key board is to array several elastic single body with a managing tool and to fix them by a vacuum adsorbing device, to glue a base board by screen printing to form a hollow coil glue coating section, to cover the base board on the managing tool and a make glue coating section fit with the flanges of the elastiic single bodies, to blows the bonded body of base board and the elastic single body away from the managing tool, to dry for certain time so as to obtain the final product of the integral elastic element.

Description

technical field [0001] The invention relates to a structure of an elastic element for a computer keyboard, in particular to a method for manufacturing an integral elastic element for a computer keyboard which is easy to manufacture and has low manufacturing cost. Background technique [0002] Such as figure 1 , 2 As shown, the structure of a general computer keyboard 9 is that a circuit board 2, an elastic element 3, a bridge 4 and a key cap 5 are arranged on the top surface of a base plate 1 from bottom to top, corresponding to the keyboard keys 90 configuration, a plurality of contacts 201 will be formed on the circuit board 2, and the elastic element 3 will protrude from a substrate 301 with a plurality of elastic monomers 302, when the keycap 5 is pressed, the bridging 4 will pivot, and make the keycap 5 press the elastic body 302 so that the bottom of the elastic body 302 touches the contact point 201, so as to achieve the purpose of signal input. [0003] Taking the...

Problems solved by technology

[0004] (1) For keyboards 9 of different types and different word keys 90 arrangements, a mold must be set up to make the elastic element 3. Therefore, as long as the words keys 90 arrangement is slightly changed, the mold must be opened again, and the mold manufacturing cost High, and quite time-consuming to make

[0005] (2) For the pivot connection of the bridge 4, a pivot joint 101 and a guide slide 102 are punched on the bottom plate 1, and the base plate 301 of the elastic element 3 corresponds to the pivot joint 101 and the guide slide 102 A plurality of through-holes 303 are also punched at the positions, so that the pivot joint 101 and the sliding guide 102 can pass through upwards. However, the elastic element 3 is made of soft silicon rubber material, and the base plate 301 is When punching the through hole 303, it is not easy to punch it completely, and it needs to be inspected manually

[0006] (3) The elastic element 3 made of silicone rubber material, during the handling process, the substrate 301 is easily deformed by the ambient temperature, which will not only affect the flatness, but also form a wave shape after deformation to increase the thickness, and dust It will infiltrate through the gap formed by the waves, resulting in poor conduction
