The automatic code scanning system is mainly used to measure the size, volume, weight and other information of the express package. It is a professional 3D measurement lens or measuring the grating, supplemented by modern measurement technology to achieve the collection of express packaging information. The application field in the code scanning system is very extensive, and it has been put into use in the fields of logistics, warehousing, e -commerce, medical care, and manufacturing. All need to be used for data collection of this type of goods. The rapid development of the Internet and e -commerce, the development of domestic logistics has accelerated. In 2021, the national express delivery business volume completed 108.3 billion pieces, and the revenue exceeded the trillion yuan. We all know that the logistics is charged at the volume or weight of the parcel. It was measured by artificial ruler, which was time -consuming and labor -intensive. The workload was large, and the cost continued to increase. With the progress of society, people have new requirements for logistics speed, so many companies in logistics, e -commerce and other fields have begun to establish their own intelligent storage logistics system. The measurement accuracy of the automatic code scanning system can reach ± 1mm, and the measurement takes only 1S to achieve the functions of "quantity recipe+weighing+code scanning+camera+system docking". The measured data can be connected to the enterprise ERP/ WMS system, export data in real time for easy viewing. The whole set of dynamic volume measurement system is composed of hardware+software. The hardware part: conveyor belt assembly line, measurement lens/light curtain, code scanning lens, weighing device, industrial computer, power supply, etc. The software part: Goodscan volume measurement system. This set of code scanning systems can effectively help enterprises replace artificial operations with automation, save labor costs, improve the efficiency of logistics operations, and achieve the goal of reducing costs and efficiency.
