Automatic scissor foot assembling device

Abstract

The invention relates to the technical field of notebook keyboard production equipment, in particular to an automatic scissor foot assembling device which comprises a horizontally-arranged outer scissor placing plate, a plurality of ejector heads and a plurality of downward pressing rods. A plurality of outer scissor limiting grooves used for placing outer scissors are formed in the outer scissor placing plate. The ejector heads are vertically arranged in the outer scissor limiting grooves and used for containing inner scissors, and the ejector heads and the outer scissor limiting grooves are coaxially arranged in a one-to-one manner. The downward pressing rods are vertically arranged above the placing plate and correspond to the ejector heads in a one-to-one manner, at least two downward pressing heads are arranged on the bottom face of each downward pressing rod, and the lower pressing heads are symmetrical about the center line in the length direction of the inner scissors. According to the automatic scissor foot assembling device, the downward pressing heads are used for extruding an inner scissor body, so that deformation of the inner scissor body replaces deformation of a mounting shaft, damage is not prone to occurring, and the effect of improving the assembly yield is achieved.

Description

technical field [0001] This application relates to the technical field of notebook keyboard production, in particular to an automatic assembly device for scissor feet. Background technique [0002] With the rapid development of scientific information technology, the supporting hardware has also developed rapidly in recent years, such as notebook computers. The keys of a notebook computer are an important part of it. According to the structure of the keys, they can be divided into a crater structure, a column structure, and a scissors structure. Among them, the scissor foot structure has the advantages of stable keycap, rapid rebound and balanced pressure, etc., and is widely used. [0003] refer to figure 1 , the scissors feet include an inner shear 100 and an outer shear 200, wherein the inner shear 100 is provided with an inner through hole 101 for the key shaft to pass through, and the inner shear 100 is horizontally provided with mounting shafts 102 on both sides of th...

AI Technical Summary

Problems solved by technology

[0005] However, with the continuous development of keyboard precision, the distance between the outer side of the inner scissors and the inner side wall of the outer through hole is getting smaller and smaller, and when one of the installation shafts is first inserted into a installation hole by using the above-mentioned related technology, the other Almost all the length of a mounting shaft is outside before it is pressed down. When the external force is forced to press, due to the strength of the mounting shaft itself, it is easier to break the mounting shaft, so it is easy to cause the failure of the assembly of the scissors feet, which leads to the assembly yield rate. not tall
