Vision detection device used for detecting defects on surface of plastic medicine bottle

The invention provides a vision detection device used for detecting defects on a surface of a plastic medicine bottle. The vision detection device consists of an annular light source (1), a camera (2), control software (3), a computer (4), a photoelectric sensor (5), a point light source (6), an electrical control cabinet (7), a removing device (8) and a shield (9). The annular light source (1) and the point light source (6) are respectively connected to the interior of the electrical control cabinet (7) by virtue of power lines (10); the annular light source (1) is arranged in front of the camera (2), the point light source (6) is arranged right above products (13) to be detected; and the computer (4) is respectively connected with the camera (2) and the electrical control cabinet (7). By utilizing the vision detection device provided by the invention, the detection accuracy can reach minimum 0.5mm of the diameter of a dark spot on the medicine bottle body, and omnidirectional detection on the bottle body is realized; and real-time, rapid, accurate and long-term continuous production detection can be realized, and the detectable rate of the defects on the surface of the plastic medicine bottle can be effectively controlled to be 99.99%, thus the vision detection device provided by the invention is beneficial to monitoring product quality and has higher application value in industrialized production.

Distribution center ex-warehouse rechecking method based on commodity weight

The invention relates to a distribution center ex-warehouse rechecking method based on commodity weight. A standar deviation sigma k, a maximum Wmaxk, a minimum Wmink, the average weight of single samples of commodities and identification information and auxiliary information of the corresponding commodities are bound and stored in a database, and the weight WC of containers and corresponding container identification information and auxiliary information are stored in the database; an electronic picking form is issued from a warehouse management system, varieties, quantity and container identification information of the actual picked commodities are bound and stored in the database, the weight Wt of each picked commodity and the corresponding container identification information are bound and stored in the database, an automatic rechecking module obtains the container information of the picked commodities needing to be rechecked through a reader and calls out the relative information, calculating comparison and judgment are carried out, and if the picked commodities pass the recheck, bounding of the electronic picking form and the picked container identification is eliminated. Automatic rechecking is high in accuracy and quick, ex-warehouse efficiency of a distribution center warehouse is effectively improved, cost is low and the application range is wide.
