Description

Technical Field

[0001] This invention relates to the field of tire manufacturing, and more specifically to a method for automatically binding tire RFID chips and barcodes. Background Technology

[0002] As is well known, embedding RFID chips during tire production has become a common industry practice, aiming to enhance product traceability throughout its entire lifecycle and ensure tire quality, safety, and compliance management. The application goals of this technology have expanded from initial quality traceability and anti-counterfeiting management to regulatory compliance. For example, the EU stipulates that from 2027, tires must use RFID chips as data carriers to provide a Digital Product Passport (DPP) that complies with the Sustainable Product Ecodesign Regulation (SPRRD), used to record information throughout the entire lifecycle, such as carbon footprint and recycled materials, to promote the development of a circular economy. In traditional tire production, after the RFID chip is embedded in the tire, it relies on manual operation using an RFID scanner to establish a link between the tire barcode and the chip. This manual operation is inefficient and prone to errors, often resulting in missed bindings, incorrect bindings, or chaotic binding relationships, making it difficult to ensure data accuracy and directly impacting subsequent quality traceability work. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides an automatic binding method for tire RFID chips and barcodes, which solves the risks of low efficiency and high error rate associated with manual binding.

[0004] The technical solution adopted by this invention to solve its technical problem is: a method for automatic binding of tire RFID chips and barcodes, using an MES system production network, characterized by including the following steps. Step 1: In the molding process of finished tire production, before the tire blank production begins, a detailed tire blank production plan including RFID tires is first formulated and issued. Then, during the actual manufacturing process of the tire blank, the RFID chip is implanted into the internal structural layer of the tire blank. At the same time, the molding machine system automatically generates and prints the corresponding barcode and affixes it to the tire bead area. Step 2: After the tire blank completes the vulcanization process and becomes a finished tire, it enters the logistics transportation line. When the finished tire passes through the panoramic scanning device, the barcode information is automatically read and the barcode data is uploaded to the MES system in real time. Step 3: The finished tires continue to move along the logistics transportation line. When they pass the RFID reader, the RFID chip information is read and the data is sent to the MES system. Step 4: After receiving the barcode and RFID chip information, the MES system performs automatic verification according to the preset binding rules. After the verification is successful, the MES system formally binds the tire barcode to the ID of its internal RFID chip and establishes a one-to-one association in the system. Step 5: For finished tires that fail the binding verification, the MES system sends a sorting and removal instruction to the logistics transportation line. The abnormal finished tires are automatically sorted and removed from the line at the abnormal exit of the logistics transportation line, waiting for subsequent manual processing or re-entry into the process.

[0005] The MES system has developed a management report module for the binding relationship between the barcode and RFID chip of the finished tire, realizing the function of unique identification and data association for each finished tire.

[0006] The reports generated by the management report module can display the binding status of barcodes and RFID chips in real time, including binding time, operator, and equipment number information, and support multi-dimensional querying and export by batch, time period, and production line.

[0007] The management report module can provide binding anomaly alerts and data audit logs.

[0008] The binding rules include information integrity, uniqueness, logical consistency, and plan accuracy.

[0009] The beneficial effects of this invention are that it realizes the automatic binding relationship between tire RFID chips and barcodes, thereby improving the level of automation, significantly reducing the subjective errors and data mismatch risks caused by manual operation, and greatly improving the processing speed and overall efficiency of the binding operation; at the same time, the system supports real-time synchronization of data to the back-end management platform, providing accurate data support for quality traceability, logistics monitoring and inventory management throughout the tire's entire life cycle. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Figure 1 This is a schematic diagram of the principle of the present invention.

[0012] The diagram shows: 1. Barcode, 2. RFID chip, 3. Finished tire, 4. Logistics transportation line, 5. PLC, 6. Panoramic scanning device, 7. MES system, and 8. RFID reader / writer. Detailed Implementation

[0013] In the figure, the present invention includes a logistics transportation line 4, the entrance end of which carries finished tires 3. The finished tires 3 have an RFID chip 2 embedded inside and a barcode 1 affixed to their outer surface. A panoramic scanning device 6 is installed on the logistics transportation line 4. The panoramic scanning device 6 is connected to a PLC 5. A set of ultra-high frequency RFID reading and writing device 8 is also installed on the logistics transportation line 4 behind the panoramic scanning device 6. Both the RFID reading and writing device 8 and the PLC 5 are connected to the production network of the MES system 7 and communicate with the MES system 7 through the PLC 5 point and TCP / IP protocol.

[0014] Working principle of the invention: Step 1: In the molding process of finished tire 3 production, before the tire blank production begins, the production management department will first formulate and issue a detailed tire blank production plan that includes RFID tires. Subsequently, during the actual tire blank manufacturing process, the machine operator will accurately implant the RFID chip 2 into the internal structural layer of the tire blank according to the process requirements. At the same time, the molding machine system automatically generates and prints the corresponding barcode 1 and affixes it to the designated area at the tire bead.

[0015] Step 2: After the tire blank completes the vulcanization process and becomes the finished tire 3, it enters the automated logistics transportation line 4 for transfer. When the finished tire 3 passes through the panoramic scanning device 6 for tire barcodes, the device automatically reads the barcode 1 information on the surface of the finished tire through multi-angle image acquisition and recognition technology, and uploads the barcode data to the MES system 7 in real time.

[0016] Step 3: The finished tire 3 continues to move along the logistics transportation line 4. When it passes the UHF RFID reader / writer 8, the device activates the RFID chip 2 embedded inside the finished tire through electromagnetic signals and reads the chip identification information stored in it. After reading, the RFID reader / writer 8 sends the chip data to the MES system 7 to complete the collection of electronic identity information.

[0017] Step 4: After receiving the information from barcode 1 and RFID chip 2, MES system 7 performs a series of automated checks according to preset binding rules, such as information integrity, uniqueness, logical consistency, and plan accuracy. Once the checks are successful, MES system 7 formally binds the tire's barcode 1 to the ID of its internal RFID chip 2, establishing a one-to-one correspondence within the system.

[0018] Step 5: For finished tires that fail the binding verification (e.g., information mismatch, unreadable chip, damaged barcode), the MES system 7 will send a sorting and removal instruction to the automated logistics transport line 4. The defective tires will be automatically sorted and removed from the line at the defect exit of logistics transport line 4, awaiting subsequent manual processing or reintroduction into the process.

[0019] Step 6: The MES system 7 developed a management report module for the binding relationship between barcodes and RFID chips on finished tires, realizing the unique identification and data association function for each finished tire. This report can display the binding status of barcodes and RFID chips in real time, including key information such as binding time, operator, and equipment number, and supports multi-dimensional queries and exports by batch, time period, production line, etc. The MES system also provides binding anomaly alerts and data audit logs, effectively improving the traceability and quality management efficiency of the tire production process.

[0020] This invention integrates an RFID reading module, a barcode scanning module, a PLC, and a MES system. It can simultaneously collect the unique identifier of the RFID chip and the tire barcode information during tire production or testing. Through preset algorithm logic, it completes data matching and associated storage, effectively eliminating subjective errors from manual operation and significantly improving binding efficiency and accuracy. Simultaneously, the system supports real-time data upload to a backend management platform, facilitating subsequent traceability and management throughout the tire's entire lifecycle.
