Abstract: Provided is a soundwave-based cup bottom detection test system which includes a feeding module, a vacuum ball, a conveying module, a voiceprint test module, a rejection module and a collection module. The soundwave-based cup bottom detection test system tests a cup bottom of a cup under test by means of sound waves and determines whether the cup under test is good. The soundwave-based cup bottom detection test system performs an effective test on the cup bottoms of the cups under test quickly by means of voiceprint testing to reject bad cups and collect good cups, thereby ensuring the high quality of the cups thus manufactured and enhancing the cup manufacturing efficiency.

Abstract: Provided is a test method for sound wave detection of a cup bottom, including: providing a sound-collecting dish, producing a good voiceprint, testing a cup under test, and performing compliance identification. Further provided is a test module which includes the sound-collecting dish, a processing unit and a memory unit. With the test method, it is practicable to perform an effective test on a cup bottom of a cup under test quickly by means of voiceprint testing to reject bad products and collect good cups, thereby ensuring the high quality of the cups thus manufactured.

Abstract: Provided is a test method for optical detection of a cup bottom, including: providing an image capturing unit, producing a reference image data, performing a cup test, and performing compliance identification. With the test method, it is practicable to perform an effective test on a cup bottom of a cup under test quickly with an image capturing unit and by means of optical testing to reject non-complying products and collect good cups, thereby ensuring the high quality of the cups thus manufactured.

Abstract: A cup assembly includes two sleeves, a bottom element, a ring and bosses. The sleeves are made of paper while the ring and bosses are made of a plastic material. The first sleeve is made with a lower edge and an upper edge. The bottom element is attached to the lower edge of the first sleeve. The ring is formed on the upper edge of the first sleeve. The bosses are formed on the first sleeve against the ring. The second sleeve is made of paper with a lower edge and an upper edge. The lower edge of the second sleeve is located against the bosses as the second sleeve is provided around the first sleeve. Thus, an adequate insulating space is defined between the first and second sleeves.
