[0002] Metal fittings typically include various structural components, transmission components, connectors, fasteners, etc., and are an important part of mechanical devices and equipment. Depending on the material, metal fittings can be divided into many types, and each type of metal fitting has its unique properties and uses.
[0003] Metal parts packaging products typically consist of multiple parts, and since packaging is usually done manually, it's inevitable that some parts might be omitted, leading to an increased defect rate. To avoid this, workers usually need to weigh the finished metal parts packaging products after assembly to prevent missing parts. However, existing weighing methods require workers to continuously place parts on the electronic scale, which is physically and mentally taxing and reduces inspection efficiency.
