Wavelet analysis on the location of extra-light and thin component and its falling gesture

According to the position and movement relationship of the lining washer with respect to the outer cover of the composite bottle cap prior to their assembly and based on the structural features of the so-called extra -light, extra-thin component with unusual shape, the strategy of the lining washer is discussed for its positioning and the process of the stopping catch is kinetically presented for the lining washer filling with the guide-key with the determination of optimized oblique angle of the guide-key. The important fact, the free-falling injection of the lining washer is also studied. With the wavelet analysis, the clearance between the guide-key and the stopping catch and the falling gesture of the lining washer with respect to the free passage in the falling course based on the experiments of the two cases, leading to determination of accurate structural and kinetic parameters that secure the lining washer entering the outer-cover precisely.
