Accurate control mechanism for manipulator key press pressure

Abstract

The invention discloses an accurate control mechanism for the manipulator key press pressure. The accurate control mechanism comprises a connecting mechanism body and a key press mechanism body, the connecting mechanism body adopts a connecting rod, and the key press mechanism comprises a pressure sensor, a metal fixing block, a supporting rod and a compression spring; and the compression spring is arranged at the upper end of the supporting rod, the upper end of the compression spring is arranged at the lower end of the connecting rod, the lower end of the supporting rod is provided with the metal fixing block metal fixing block, and the metal fixing block is connected with the pressure sensor at the bottom of the metal fixing block. According to the accurate control mechanism for the manipulator key press pressure, structural design is novel, the pressure changing influence caused by pure rigid structure displacement errors is lowered through the negative feedback effect of the compression spring, and accurate control can be achieved accordingly; and the pressure sensor is integrated, and thus the actual pressure of manipulator key press can be controlled.

Description

technical field [0001] The technical field of button pressure control of the present invention is specifically a mechanism for precise control of button pressure of a manipulator. Background technique [0002] With the continuous progress of economy and technology, people's quality of life is getting higher and higher. Products with touch screens are becoming more and more widespread, and consumers' quality requirements are getting higher and higher. How to efficiently and automatically realize the detection of the sensitivity of the touch screen also poses new challenges to electronic product manufacturers. [0003] Basically, several middle-level touch screen testing solutions currently on the market have their own defects: [0004] Manual detection: [0005] The research and development cost of artificial detection sensitivity is the lowest, but the labor cost is high. In addition, human detection also faces a repetitive problem. During the R&D and testing phase of e...

AI Technical Summary

Problems solved by technology

The sensitivity test of fixed point and constant force and the trigger detection of curve trajectory have also been greatly improved, but there is still a certain gap from the accuracy required. The main problem is: the nib in the front section is the nib used by ordinary consumers.

This kind of nib is characterized by being very soft, mainly to meet the daily operation, its deformation and sensitivity itself are not controlled according to the level of detection equipment, so it is impossible to feedback the pressure in real time
