The accurate number of the waveform gaskets cannot be accurately judged by detecting the waveform gaskets by using a separate distance sensor, and the reason is mainly that the waveform gaskets cannot be detected due to the size difference of wave crests and wave troughs of the waveform gaskets, the height tolerance of the gaskets and the randomness of the waveform gaskets in the circumferential direction in the placing process.
