[0002] In the field of high-end musical instrument manufacturing, the piano, as the "king of instruments," is greatly affected by the tone quality of each component. The bonding of the felt in the piano keys is one of the key links. The felt plays an important role in the piano keys, such as damping, cushioning, and stabilizing the key touch. The bonding effect between the felt and the keys directly affects the piano's performance and tone. When bonding the woolen fabric of piano keys, it is usually necessary to manually place the piano keys on the limiting blocks first, and then use the glue applicator to bond the joints. Because the bonding positions are staggered on both sides, after bonding one position, the piano key in the limiting block must be removed, flipped, and then the limiting block is reapplied, making the process cumbersome and increasing the workload of the workers. In order to solve the above problems, the inventor proposed a woolen bonding device based on piano keys. Utility Model Content
