Plastic material quality prediction method

Abstract

The invention relates to the technical field of plastic materials, in particular to a method for prejudging the quality of plastic materials used for keyboards. The method includes the steps that before every batch of plastic is normally put into production, a testing plate is manufactured through the plastic, wherein the testing plate comprises a sheet-shaped base plate body, a plurality of studs are perpendicularly formed on the base plate body, and the apertures and the height of the studs on the testing plate are coincident with the apertures and the height of studs of the keyboards; the studs are tested through a digital torsion tester, stud locking operation is carried out with the maximum reference force, it is judged that the batch of plastic does not meet the requirement if at least one stud is burst, and it is judged that the batch of plastic meets the requirements if no stud is burst. By means of the method, the stress of the studs formed by the batch of raw materials in an injection molding mode can be tested before mass production of the keyboards, production can be carried out if the requirements are met, and the plastic is not put into production if the requirements are not met, quality prejudgment is achieved, the reworking rate of the products is greatly reduced, defective products are reduced, waste of production cost, manpower resource cost, transport cost and storage cost is reduced, and the method is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of computer keyboards, in particular to a method for predicting the quality of plastic materials used in keyboards. Background technique [0002] With the continuous development of electronic technology, computers are becoming more and more popular. Basically, a computer is equipped with a keyboard. Gradually, independent products with various shortcut functions are sold separately on the market. No matter what kind of keyboard, basically They are all made of plastic, and the widely used keyboard includes a keyboard panel and a base, and the keyboard panel and the base are locked by screws. There are screw posts and holes formed on the keyboard panel and the base, and the hole diameters of the screw posts at different positions may be different, and the force range of each screw post may be different. In addition, the injection molding raw materials used in each batch of keyboards may be different, and the ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a method for predicting the quality of plastic materials in view of the deficiencies in the prior art, which solves the defects existing in the existing keyboard production: the screw column may be squeezed and burst when the keyboard is assembled, and all processes are reworked.
