Electroplating production lines rely on RFID technology for product upgrades

Electroplating production lines are a classic and successful example of intelligent upgrades using RFID technology. Leveraging RFID, traditional electroplating lines can achieve a qualitative leap from "experience-driven" to "data-driven."

Electroplating is a crucial link in the industrial chain, with widespread applications across various sectors. Its expansion into the electronics, micro-electromechanical systems, and steel industries has driven the industry's development towards intensification and scale, necessitating continuous technological advancement. Furthermore, production environments are subject to high levels of dust, high temperatures and humidity, corrosion, and poor visibility. Traditional barcodes and QR codes face significant limitations in production, prone to read failures or errors. RFID radio frequency identification technology offers numerous advantages over barcodes and QR codes, including long read range, operability in harsh environments, identification without the need for visible label visibility, the ability to update label content, high-speed identification of moving objects, and ample data storage capacity. Therefore, the use of RFID technology can enable data collection on electroplating production lines. Combined with existing equipment, it can significantly improve automation levels, enhance the accuracy and reliability of data collection, and significantly increase production efficiency, improve material utilization, and reduce product rejection rates.

The following is a detailed explanation of how electroplating production lines can achieve comprehensive product upgrades using RFID technology:

Pain Points of Traditional Electroplating Production Lines

Opaque Processes: After a workpiece enters the production line, information such as its specific location, current tank, and processing time relies entirely on manual recording or empirical judgment, creating a "black box" state.

Difficulty in Process Error Prevention: Different workpieces require different electroplating processes (such as plating type, current, and time). Manual errors (such as attaching the wrong plating bar or selecting the wrong program) can easily lead to entire batches being scrapped, resulting in significant losses.

Weak Traceability: When quality issues arise, it's difficult to accurately trace the specific stage where the problem occurred (was it incomplete pretreatment? Or insufficient copper plating time?), resulting in the entire batch being scrapped or returned, making it difficult to analyze the cause.

Low Production Efficiency: Manual workpiece identification and equipment parameter settings are required, resulting in a low level of automation and bottlenecks in production efficiency.

Complicated Data Recording: Production data (such as operator, time, and process parameters) relies entirely on manual report filling, which is labor-intensive, prone to errors and tampering, and hinders digital management.

Application of RFID Technology in Electroplating Racks

Rack Tag Initialization: Electroplating plants bind uniquely coded RFID tags to rack component information, with each component assigned an RFID tag. Rack Tag Identification: When electroplating plant employees place components on racks, RFID plating readers automatically identify all rack information entering the spraying process and upload it to the system console. The system then automatically counts rack usage and provides notifications for repairs and scrapping. It also transmits component type and process information to relevant process equipment to ensure proper operation. Workflow: When a rack carrying an RFID tag enters the workbench, the RFID electroplating reader automatically identifies the rack tag within its working range, obtains the tag information in real time, and transmits the read tag information to the relevant process equipment. This ensures the completeness of the production process, monitors the production process and process of electroplated products, and improves the standardization and informatization of product management.

High-temperature and corrosion-resistant tag carrier logistics management: The electroplating process requires a large amount of chemicals, all of which pose environmental and safety risks. Therefore, electroplating Logistics Management, especially chemical monitoring and management, utilizes RFID technology to monitor the location, quality, packaging, and other information in real time online, ensuring the traceability of hazardous materials from production to transportation, storage, and collection. Any process that has not been read and confirmed by the RFID electroplating reader cannot pass the corresponding checkpoint. The amount and whereabouts of hazardous materials are clearly monitored, greatly ensuring safety.

RFID technology provides upgraded solutions: The core of the RFID system is the installation of high-temperature, acid- and alkali-resistant, and corrosion-resistant industrial-grade RFID tags on dedicated electroplating racks or flybars. RFID Readers are installed above each key process tank (such as degreasing, pickling, copper plating, nickel plating, and chromium plating) or at track nodes.

1. Upgrade 1: Achieving Full-Process Automation and Intelligent Control

Process: When a hanger carrying a workpiece enters a tank, the reader at that station automatically reads the RFID tag ID on the hanger.

Action: Based on the workpiece information corresponding to the tag ID (e.g., "Part A - Galvanizing Process"), the system automatically issues instructions to the PLC (Programmable Logic Controller) to retrieve the preset process parameters (e.g., 100A current, 30 minutes time).

Result: The electroplating power supply automatically uses the correct parameters for processing, requiring no manual intervention. This achieves "material-driven equipment," fundamentally eliminating human error.

2. Upgrade 2: Establishing a Full Lifecycle Traceability System

Process: The RFID tag serves as the workpiece's unique "identity card." Once linked to it, all production data is recorded and linked to this ID in real time.

Recorded Information:

Material Information: Workpiece model, batch, and customer.

Process Information: Actual processing parameters, start/end times, and operator for each trough.

Quality Information: Online quality inspection results, final quality inspection data, and packaging information.

Result: A complete "one item, one File" digital traceability record is created. In the event of a complaint, simply enter the product number and the product can be traced back to every production step within minutes, pinpointing the root cause and enabling precise quality management and recalls.

3. Upgrade Three: Improving Production Transparency and Scheduling Efficiency

Process: The reader/writer network on the production line forms a real-time location system.

Action: Managers can view the following in real time on the MES (Manufacturing Execution System) dashboard:

The real-time location and status of each hanger (pending, in progress, completed).

The current production line capacity and efficiency (OEE), as well as any bottleneck processes.

The expected completion time.

Result: The production process has been transformed from a "black box" to a "transparent box," enabling visual management. Scheduling personnel can use real-time data to make more informed production scheduling and resource allocation.

4. Upgrade Four: Optimizing Production and Energy Costs

Precise Control: Automated process control avoids rework and scrap caused by parameter errors, directly saving raw materials and energy.

Process Optimization: By analyzing the extensive process data collected by RFID, it is possible to identify process waste (e.g., whether the time for a particular tank can be shortened), thereby further optimizing the process flow and reducing water, electricity, and chemical raw material costs.

Key Implementation Considerations

Tag Selection: Select tags specifically designed for the harsh electroplating environment, featuring strong resistance to high temperatures, acids and alkalis, and metal interference.

Reader Installation: The reader must be mounted in a location that ensures stable reading of moving tags, while also ensuring proper protection from chemical corrosion.

System Integration: The RFID system must be deeply integrated with the existing MES, ERP, and electroplating equipment control system (PLC) to maximize its value.
