Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] There are two types of parts error prevention in the existing automobile final assembly line. One is manual error prevention (is it to check / verify whether the part model matches): according to the vehicle's appearance characteristics, license plate and other information, the vehicle model configuration is manually judged and the corresponding parts are picked up; the other is traditional code scanning error prevention, which scans the vehicle VIN (vehicle identification) code, vehicle VSN (vehicle configuration) code, and part barcode in turn, and then matches the corresponding VSN-part number database to achieve code scanning error prevention. These two error prevention methods require more time and energy from assembly workers to handle, which makes the assembly efficiency low and is also prone to assembly errors due to human errors.
