Error prevention management
:
The application of radio frequency technology on the assembly line to produce as many customized cars as possible is based on the requirements of the user. The user can choose the color and engine of the car from tens of thousands of internal and external options. Models and tire styles are also required. In this way, the automobile assembly line has to assemble hundreds of styles of cars. Without a highly organized and complex control system, it is difficult to complete such a complex task.Equipped on the assembly line
RFID
The system uses a reusable radio frequency tag. The radio frequency tag can contain all the requirements of the car in detail. There is a reader at each work point, which can ensure that the car can be Complete assembly tasks in error.
Warehouse management
:
Spare parts management: establish complete supplier delivery quality records and batch information: each supplier can carry out label records for the parts that each supplier enters the enterprise according to the electronic version, and understand its model, type, batch, production date, etc., Carry out warehouse-in and out-warehouse management.
Real-time monitoring of the production line
:
Carry out the entire production process from the product entering the assembly workshop to the final inspection of the vehicle
RFID
Tracking management.
Cost Control
:
Use modern logistics theory to improve the storage of auto parts and complete vehicles, save costs, and save the waste of production and temporary inventory in each workshop of the enterprise.
Product traceability
:
my country has formally implemented the automobile recall system, which puts forward higher requirements for product traceability. Product traceability requires detailed production site records, including all aspects of production, quality, and materials.
according to
RFID
The label information can be used to query the production and manufacturing information of each key station of the vehicle in the assembly workshop in real time, such as production time, operator, inspector, batch, serial number, quality data, process data, test data, etc., and understand the manufacturing process Information, such as repair and processing results.
according to
RFID
Label information, you can inquire about the quality information of the vehicle at important stations, including defect data and measurement data, as well as various data such as the process capability of the station;
according to
RFID
Label information, which can trace the quality information of the important parts and safety parts of the car, the information of the manufacturer of the main accessory parts, the specific details of the installation and other related information;
According to product information, which can be traced back to product batches and key component batches, find out other products of the same batch;
Upward can be traced to materials and components, and downward can be traced to end users.
Defect management
:
The whole vehicle production is mainly assembled, involving a large number of parts (including in-house self-made parts and outsourcing parts). Various defects are unavoidable during the assembly process. Some defects come from parts, some are produced in this process, and there are also previous processes. produced. In order to improve the quality and reduce the repair rate, it is necessary to monitor the defects of each car in real time, record them in real time, and take timely measures.
Application effect
:
1
, The electronic tag can be read multiple times (up to
10
Ten thousand times)
2
,
RFID
The electronic tag can be stably read by the reader (low error rate).
3
, Can save a lot of manpower and time.
4
, The command of the main system to the production process is comprehensively improved.
5
, The whole production process and the main system are connected together, and the production efficiency is greatly improved.
Principles of the plan
Establish a unified central database on the site of the enterprise workshop as an information platform for the circulation of goods to facilitate overall standardized management.Use in industryRFIDTechnology assigns an identification number to each work-in-progress component (ID), which is the name of the component in the information network, throughRFIDTechnology, map the production status and inventory status to the information network, register it in the field center database, and then transmit it to the information system (such asERP,MRP)Wait.
basic structure
typicalRFIDThe automatic identification system consists of the following parts: data carrier, reading/Write unit and interface module. The interface module communicates withPLC,PCWait for the control unit to connect
