Description

Technical Field

[0001] The utility model belongs to the technical field of laser marking devices, and specifically relates to a laser marking, visual weighing and detection integrated machine. Background Art

[0002] With the development of the times, people have higher requirements for product traceability, and basic product traceability codes are indispensable. This is especially true for products such as food, medicine, and cosmetics that affect human health. Basic identification such as the production date, production batch, and expiration date are crucial for product safety. Laser marking and the accuracy of the marked characters require visual inspection, and product weight inspection is also required to determine whether there are any missing or overpacked items, protecting the interests of both consumers and manufacturers.

[0003] Currently, most products use inkjet printers to print the three-phase code, and then use visual inspection to detect errors and missing characters in the three-phase code. Product weight is checked manually by random inspection, with three types of machines operating separately. Products are manually unloaded and operated at multiple stations, requiring multiple personnel to operate. Utility Model Content
