[0002] After packaging, products need to be inspected. In the past, product inspection had to be done manually, with the packaging weighed, surface photographed, and barcodes entered. The entered barcodes had to correspond one-to-one with the weight and photos. Products with unqualified weights also needed to be picked out during the process. The operation was cumbersome and there was a possibility of misoperation. For this reason, many workbenches that assist in inspection have appeared on the market. Workers only need to put the packages in for automatic weighing, photographing, and barcode entry. However, this method still requires manual positioning and screening, and the efficiency improvement is limited. Utility Model Content
