專利摘要(中)
一種異質材料的超音波焊接方法，包含：將壓電片置於熱塑性基座的定位槽，並用超音波焊頭接觸壓電片以進行超音波焊接處理，超音波焊頭具有用來與壓電片接觸的貼靠平坦面部，且超音波焊頭在貼靠平坦面部欲接觸到壓電片時開始震動而進行超音波焊接處理，貼靠平坦面部與壓電片接觸的時間為大於0.1秒且1秒以下，使熱塑性基座與壓電片接觸的表面融化後固化2秒至5秒讓兩者接合。本發明另提供一種包含熱塑性基座及壓電片的動力計。熱塑性基座包括定位槽且界定出用以供動力計受力後而產生形變的空間。壓電片設置於定位槽且被焊接於熱塑性基座上。

專利摘要(英)
This invention provides a ultrasonic welding method of heterogeneous materials, which comprises following steps of: placing a piezoelectric film in a positioning groove of a thermoplastic base, and contacting said piezoelectric film with an ultrasonic welding head for ultrasonic welding, wherein said ultrasonic welding head has a flat surface, which used to contact with said piezoelectric film, and said ultrasonic welding head starts to vibrate and perform ultrasonic welding when said flat surface is about to contact said piezoelectric film, a contact time between said flat surface and said piezoelectric film is greater than 0.1 second and below 1 second, so that a surface of said thermoplastic base contacting with said piezoelectric film melts, and making said thermoplastic base and said piezoelectric film to joint after curing for 2 seconds to 5 seconds. Said invention further provides a dynamometer, which comprises a thermoplastic base and a piezoelectric film. Said thermoplastic base includes a positioning groove, and defines a space for said dynamometer to generate deformation after a force. Said piezoelectric film is arranged in said positioning groove and welded on said thermoplastic base.
