Elasticity and displacement amount measuring device and method, application thereof

Abstract

The invention discloses elasticity and displacement amount measuring device and method application thereof. The elasticity and displacement amount measuring device is characterized in that a displacement sensing module and a force sensing module are arranged on both ends of a shaft lever; a baffle-board of the displacement sensing module can displace with the shaft lever in the process that the shaft lever is moved and a probe of the force sensing module presses a measured key, and an optical sensor measures a displacement amount; after the probe of the force sensing module presses the measured key, a sensing sheet can be deformed, and the size of elasticity is measured by a strain gauge, therefore the elasticity and the displacement amount can be synchronously measured by the force sensing module and the displacement sensing module. Besides, when the displacement amount measuring method is in use, a measure stroke is divided into a plurality of measuring ranges, and each measuring range corresponds to an arithmetic model to accurately calculate the distance values of measured distance data.

Description

technical field [0001] The invention relates to the technical field of button measurement, in particular to a measuring device, application and method capable of synchronously measuring elastic force and displacement. Background technique [0002] Buttons have been widely used in electronic products, such as computer keyboards, mobile phones, telephones and so on. In order to allow users to operate and use the keys more comfortably, the manufacturer has formulated a suitable key elastic mode through years of experimental tests, so as to measure its products when manufacturing keys, and this type is used for measuring keys. Measuring equipment for elastic force also came into being. [0003] If China Taiwan's new patent announcement No. 529714 "Key Elasticity Measuring Machine" is an example, it is driven by a motor to lift a lifting plate, and a buffer seat is combined on the lifting plate to assemble the measuring instrument, and the measuring instrument is used The test ...

AI Technical Summary

Problems solved by technology

[0007] Therefore, the current measurement of the keys on the wind instrument is to use a tensile micro-force meter to cooperate with a scale measuring instrument (or use a large servo motor) to achieve the purpose of measuring the elastic force and displacement, but such a measurement method Still has the problem of being bulky and expensive

[0008] There is another technology that uses laser distance measuring equipment to measure displacement, but the installation cost of laser distance measuring equipment also has the problem of high price
