An automatic assembly device for scissor feet

Abstract

This application relates to the technical field of notebook keyboard production equipment, in particular to an automatic assembly device for scissor feet, which includes: a horizontally arranged outer scissors placement plate, and a plurality of outer scissors for placing outer scissors on the outer scissors placement plate Limiting groove; vertically arranged in the outer shear limiting groove for placing a plurality of plugs of the inner shear, the plug and the outer shear limiting groove are arranged coaxially; a plurality of lowering rods vertically arranged above the placement plate, The lower pressing rods are set corresponding to the heads one by one, and the bottom surface of each lower pressing rod is provided with at least two lower pressing heads, which are symmetrical about the midline in the length direction of the inner shear. In this application, the lower pressing head is used to squeeze the inner shear body, so that the deformation of the inner shear body replaces the deformation of the installation shaft, which is not easy to be damaged, and has the effect of improving the assembly yield.

Description

Technical field [0001] The present application relates to the technical field of notebook keyboard production, in particular to a scissor foot automatic assembly device. Background [0002] With the rapid development of scientific information technology, the hardware supporting it has also developed rapidly in recent years, such as notebook computers. The keys of the notebook computer are an important part of it, and according to the structure of the keys, they can be divided into crater structure, column structure, scissor foot structure and so on. Among them, the scissor foot structure has the advantages of keycap stability, rapid rebound, pressure balance, etc., and is widely used. [0003] Reference Figure 1 , scissor feet include internal shear 100 and external shear 200, wherein the inner shear 100 is opened for keyshaft through the internal hole 101, the inner shear 100 length direction on both sides of the horizontally provided with mounting shaft 102, on the outer shear ...

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 using the above-mentioned related technology to insert one of the mounting shafts into a mounting hole first, 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
