Tail plug defective product detection device and detection method

Abstract

The invention relates to a tail plug defective product detection device and method. The device comprises a first annular belt, a second annular belt and a third annular belt which are sequentially arranged from top to bottom. Gaps matched with the thickness of a workpiece are formed between the first annular belt and the second annular belt and between the first annular belt and the third annular belt; a first positioning groove, a second positioning groove and a third positioning groove for positioning the tail plug are respectively formed in the outer side surfaces of the first annular belt, the second annular belt and the third annular belt in the length direction; the driving mechanism is used for driving the first annular belt, and the first CCD camera and the second CCD camera are respectively used for acquiring images of the front ends of the tail plugs positioned above and below the first annular belt; the first CCD camera and the second CCD camera are obliquely arranged upwards; and the first guide groove rail is used for conveying the tail plug located below the first annular belt to the upper surface of the first annular belt, so that rapid, accurate and efficient detection of the tail plug is realized.

Description

technical field [0001] The invention relates to the technical field of defective product detection, in particular to a tail plug defective product detection device and detection method.

[0002] Electronic products are common tools in daily production and life. With the advancement of science and technology, various electronic products play an increasingly important role. Various electronic products with various functions greatly facilitate people's production and life, such as mobile phones, computers, portable charging Devices, etc.; the demand for electronic products is increasing year by year, but the production and processing of most domestic electronic product components is still at the manual stage. In particular, for the tail plug, the rear end has outlet terminals for internal circuit connections, and the front end There are slots for the connectors of external devices to be plugged in. There are fixed tongues inside the slots. There are connecting gold fingers on the upper and lower sides of the fixed tongues. The most prone to problems during the production process is the inside of the slots. Gold fingers are prone to problems such as warped pieces, deformation and distortion, so the quality inspection of the tail plugs is required before delivery, and it is necessary to ensure that the gold finger connectors inside the slots are flat, level and free of bends. Currently, The detection of tail plug terminals is completed by human eyes. During the inspection process, employees need to pick up the tail plugs and turn them over to conduct a comprehensive inspection of the golden fingers on both sides. This leads to low production efficiency and cannot accurately control product quality. The production cost is high, and the control of product delivery is not strict enough
