Project Description
After the automatic spraying robot is introduced into the spraying production line, workers must manually set the working parameters of the spraying robot by observing the types of parts and other information to correctly set the process parameters of the parts to be processed. Manual settings will not only affect the production efficiency of the production line , And it’s extremely error-prone.
Due to the large amount of dust, high temperature and humidity, corrosion, and poor visibility in the spray production environment, automatic barcode recognition technology cannot be applied. Compared with Barcode technology, RFID technology has many advantages, such as long recognition distance, no need for visual visibility of tags during recognition, can be used in harsh environments, content can be updated, multiple tags can be read in batches, high-speed recognition Sports items, large amount of information, not easy to imitate, etc.Therefore, UHFRFIDThe technology realizes the data collection of the key procedures of the automatic spraying production line, and efficiently cooperates with the automatic production line and the spraying robot system, which overcomes the existing problems in the current system, improves the reliability and accuracy of the data collection of the spraying production line, and greatly improves Productivity.
Key process
Hook labeling: Embed the temperature and corrosion resistant metal RFID tag on the hook of the workpiece;
Workpiece hook: When the workpiece is hooked, manually scan the bar code or input the manufacturing number of the current workpiece through the keyboard, and obtain the reportable model code corresponding to the workpiece through the host computer program, and add it to the waiting queue for spraying;
Hook writing mark: When the workpiece enters the sensor area of the initial process, the upper computer program will operate the RFID device to write the corresponding model code of the workpiece into the storage area of the hook RFID tag according to the workpiece placement instruction sent by the PLC;
Marking reading for spraying: When the workpiece enters the spraying process area, the RFID equipment automatically receives the sensor signal and reads the model code of the current workpiece stored in the hook tag, and returns it to the upper computer program, which transmits the model code through the PLC Spraying robot;
Tag clearing: After the workpiece completes the spraying process and enters the clearing station, the RFID device automatically receives the sensor signal and clears the storage area of the hooked RFID tag. When the clearing fails, it will immediately return to the upper computer program and send an alarm through the on-site alarm. The machine program controls the shutdown of the production line through the PLC;
Device Configuration
Reading and writing equipment: According to the requirements of the site environment, configure our company’s high-protection, integrated, high-performance industrial-grade integrated reader (RS485 communication interface, 1 photoelectric isolation input/1 relay output, AC220V/0.2A) Power supply, IP65);
Electronic tags: Special temperature-resistant, corrosion-resistant and metal-resistant electronic tags ST-2525C.
Implementation benefits
1. Automatically collect information such as the part manufacturing code of the spraying process and the model code of the spraying process, which provides an information basis for automatic spraying;
2. Information technology combines sensor technology, automation technology and RFID technology to realize the automation of the whole process of the spraying production line and realize the true integration of the two;
3. The automation of the spraying production line greatly reduces the on-site staff and effectively reduces the damage to the human body caused by dust and paint;
4. Improve the production efficiency of enterprises, reduce labor intensity, and reduce errors;
5. Improved the level of enterprise information management.
