A computer button without clipping feet and scissor feet, and assembling equipment and method

Abstract

The invention relates to an assembling apparatus and a method of a computer button of a clamping-pin free scissor pin. The button comprises a button cap, a scissor pin, an elastic colloidal silica body, and a printed circuit film. The inner frame body is a symmetric and rectangle frame body, wherein the inner frame body is formed by the connection of an inner frame forearm, an inner frame rear-arm, an inner frame left arm, and an inner frame right arm. The outer frame body is the symmetric and rectangle frame body, wherein the outer frame body is formed by the connection of an outer frame forearm, an outer frame rear-arm, an outer frame left arm, and an outer frame right arm. After assembled, two gourd-shaped concave groove clamping seats in the button are rotatingly clamped with the outer frame body forearm. A lateral clamping hook of the button cap is slidingly connected with the inner frame body rear-arm in a butt joint mode. Two gourd-shaped concave groove clamping seats of a baseboard are rotatingly clamped with the outer frame body rear-arm. A lateral clamping hook of the baseboard is slidingly connected with the inner frame body forearm in a butt joint mode. The invention further relates to the assembling apparatus and the method of the computer button of the clamping-pin free scissor pin. The assembling apparatus and the method of the computer button of the clamping-pin free scissor pin has the advantages of being suitable for machine automation assembly, capable of reducing the vibration of the button cap, low in cost, and the like.

Problems solved by technology

[0002] With the development of the information industry, computers are increasingly widely used. Whether it is a notebook or a desktop computer, computer keys are inseparable. figure 1

The disadvantages of this type of structure are as follows: First, the cost is high. The traditional scissor foot structure not only has high mold manufacturing costs, but also high injection molding production costs, difficult to control quality, consumes a lot of manual assembly, higher labor costs, and low production efficiency. Current headaches in the industry

Second: The structure is not firm, and the keycaps are easy to shake

In the future, scissor keyboards will all be ultra-thin structures, so the structure of the scissor feet is extremely precise. The diameter of the shaft is only 0.5-0.7mm, and the diameter of the frame is generally only 1-1.2mm thick. In addition, this kind of uneven traditional structure affects the Its support strength makes it easy to shake the keycap when the inner and outer scissor brackets go up and down. Third: this type of structure cannot maximize the support surface of the scissor foot bracket, the keycap and the key bottom plate. When the finger is not pressed in the keycap There will be shaking and unevenness when pointing, which will affect the comfort of the hand feeling

Fourth: When assembling the inner frame and outer frame of traditional scissor feet, it is necessary to open a slot above or below the shaft hole. This is convenient for installation, but it reduces the strength after assembly. When the keyboard is accidentally hit or dropped , the inner frame and the outer frame are easy to fall off from the opening of the slot, such a structure is not strong enough

Fifth: The structure of the traditional scissors is complex and irregular, manual assembly is difficult, and the production efficiency is low, so it is impossible to realize mechanical automatic operation. One of the reasons: the traditional scissors structure has many docking points. There must be four outstretched column shafts outside the frame, and four docking points on the bottom of the keycap and the bottom plate of the key. One key needs to be equipped with eight sets of docking points, and one keyboard has 101 keys. 808 docking points need to be installed. Manual assembly of so many docking points is inefficient, high cost, and inconvenient for mass production

The second reason: when a large number of such traditional scissor legs are piled up together, because the outer frame body and the inner and outer frames have shaft columns and frame holes respectively, they are intersected and mixed together, it is difficult to distinguish manually, and the machine cannot identify the ranking. Realize mechanical automation
