Full-automatic piano tuner and system

Abstract

The invention discloses a full-automatic piano tuner and system. The full-automatic piano tuner and system is characterized by comprising a motor assembly, lateral supports are arranged at two ends above the motor assembly, at least two top cover supports are arranged between the lateral supports, gear guide rails are arranged between the lateral supports and the top cover supports respectively, a box is arranged at the lower end of the motor assembly, a circular-arc-shaped clamping groove is formed in one face of the box, a piano tuning wrench head is arranged in the clamping groove and moves along the same in an arc-shaped manner, an image recognizing and positioning device is arranged below the clamping groove, an infrared positioning device is arranged on one side of the image recognizing and positioning device, and a manipulator is arranged on the lower portion of the box. The full-automatic piano tuner and system is simple in structure, convenient to operate and supportive of batch production, cost is controlled effectively, and devices can be utilized to replace manpower to realize full-automatic tuning.

Description

technical field [0001] The invention relates to a fully automatic piano tuner and system. Background technique [0002] In modern society, people are becoming more and more familiar with the piano. Many children have been exposed to piano education in childhood. Therefore, pianos are becoming more and more common in society. There are more than 200 strings in the piano, and each string bears The tension of the instrument is about 90 kg. After a period of playing vibration and the influence of temperature and humidity changes, the tension will drop and affect the intonation, which is often called "variation". This is bound to affect our hearing experience. Especially novice children need to establish a good concept of fixed pitch from the beginning. Therefore, piano tuning and mechanical finishing are performed 1-2 times a year. If the tuning takes a long time, it will cause the pitch to deviate too much. "The piano should be moved slightly, not too much" is good for the p...

AI Technical Summary

Problems solved by technology

If the tuning takes a long time, it will cause the pitch to deviate too much. "The piano should be moved slightly, not too much" is good for the piano itself and the strings. With the increase of tension, the piano will have an adaptation process under the new balance state, the sound will drop rapidly, and it needs to be adjusted several times to keep the sound stable, which increases the difficulty of piano debugging

In the prior art, manual adjustment is generally used, and an "L"-shaped tuning wrench is used to judge the pitch by the human ear and perform non-coaxial torque adjustment. The sound process requires heavy manpower consumption is getting widespread attention
