With the rapid development of manipulator applications, there are more and more manipulator applications, especially those that cause harm to personnel. Therefore, the varieties of manipulator parts have begun to vary, and the output has also increased. In the face of the complex variety and huge quantity of manipulator parts, the traditional production management method is to use labor to manage the production of manipulator parts. The key to work efficiency lies in employees, so it is related to the products of manipulator parts during the work process. The speed and accuracy of information reading and recognition will have a certain impact, and the final result will affect the work efficiency and even the ant quality of the manipulator parts. Facing the existing management status of the manipulator, try to use automatic identification technology to improve the management status of the manipulator parts. At present, the existing automatic identification technologies mainly include barcodes, smart cards, magnetic cards and RFID technologies.
1 Management of manipulator parts production line
Using RFID technology to realize automatic control and monitoring of products on the production line of manipulator parts will greatly improve the speed and accuracy of production, increase work efficiency, improve production methods, and save costs. RFID tags can conveniently and accurately record process information and process operation information on the robot parts production line to meet the needs of flexible production. The record of worker ID, time, operation, and quality inspection results fully realizes the traceability of production, and can also avoid errors caused by handwriting and seeing information in the production environment.
Take Haier Group as an example. In 2003, Haier Group began to track RFID technology. Haier hopes to play the role of RFID technology in automatic identification reading, group reading, and remote reading, instead of the original short-distance manual bar code reading method. Work efficiency, and in the longer-term future, in some possible business processes, data is captured through RFID tags, thereby significantly improving the level of supply chain management. Learning from Haier’s experience, once the chip technology has developed to a significant reduction in cost and large enough storage capacity, chip tags should be embedded in the robot parts product-which records the data during the manufacturing process, such as the raw materials of the robot parts, the model of the robot, and the robot. Part surface roughness, etc., can also record customer and product warranty information. In this way, on the production line of manipulator parts, employees can automatically read the data in Table 1 in the label affixed to the manipulator parts through the system, so that the product information of the manipulator parts is clear, as shown in Figure 1.

Similarly, on the assembly line can also be managed by RFID technology. For example, to assemble a set of manipulator model A, as shown in Figure 2, by identifying the model information on the RFID tag to determine whether it is the model of the part to be assembled, if it is, it will be put into the next process to wait for assembly, if it is not, it will be screened Lose.

2 Warehouse management of manipulator parts
At present, the warehouse management of manipulator parts is mainly realized based on the corresponding standardized manual operations and computer semi-automatic management. The disadvantage is that a large amount of manpower is required to standardize the placement of items, regular inventory, and exit/entry registration. This makes the warehouse management of manipulator parts very cumbersome and wastes a lot of time. The design of the warehouse management system for manipulator parts based on RFID technology is to realize the automation of item out/in control, item storage location and quantity statistics, and information query process, which is convenient Managers conduct statistics, inquiries and grasp the flow of materials. Take the warehouse management of Shenzhen Baisha Logistics as an example. Before the end of 2004, the incoming and outgoing goods in the warehouse of Baisha Logistics Base in Shenzhen were all put on pallets for management. The amount of goods is huge, and the work intensity of the warehouse manager is very high. It is inevitable that errors will occur in this process, resulting in excessive management costs and poor management efficiency.
The same problem is believed to also exist in robot parts. For this reason, imagine using RFID technology to propose the following solutions. First, a UHF label is affixed to each pallet that enters and exits the robotic parts warehouse, and readers are installed on the doors of the warehouse. Each warehouse manager has a handheld machine that also has infrared collection. Features. In this way, before each batch of robot parts enter the warehouse, the warehouse manager uses the handheld to scan the barcode of the robot parts on each pallet, record the robot parts, and write them into the label on the holder under the robot parts through RFID. When the manipulator parts enter the warehouse, the reader on the door will directly read the information of the manipulator parts on the label and store it in the computer. The back-end information management system will automatically generate records and accurately record the batch of manipulator parts. In which position in the warehouse, there is no longer any need to ship, and warehouse management personnel need to look for it row by row. If someone pushes the pallet out of the warehouse, the back-end system will immediately show that these manipulator parts are out of the warehouse and automatically generate a time record. In this way, there will be no trouble that the warehouse management personnel forget to input the information into the computer due to the negligence of the warehouse management personnel, and it will be difficult to check the data after the problem occurs, and if the warehouse management personnel themselves do not know how to operate the computer, it will not be generated for information management. problem. By analogy, if a UHF label is affixed to each manipulator part, each manipulator part entering and leaving the warehouse will be immediately displayed on the back-end system, which optimizes the entire management program and reduces the incidence of human error in the management process. , It also saves management labor costs. As shown in Figure 3, the entire supply chain management process of manipulator parts is simplified and more scientific.
The RFID technical solution assists the completion of the warehouse management of manipulator parts in such a process. RFID tag is the carrier of data and information in the storage management of manipulator parts. RFID reader is the method of collecting data and information in the management of manipulator parts. It is directly linked to the manipulator parts storage management system through a software interface, making the object of storage management- —– The details of the manipulator parts can be displayed in the entire warehouse management information system of the manipulator parts as long as they pass through the reader. In today’s logistics integration, many employees can be liberated from this simple but tedious work.

3 Management of robot parts in the supply chain
The application of RFID technology in the supply chain management of manipulator parts is still in its infancy. However, the understanding of RFID technology in various companies, especially multinational companies, has risen to a new stage. Storage, packaging, loading/unloading/handling, circulation addition, distribution, sales to service are all interlocking business links and processes in the supply chain. They are complementary and mutually restrictive. In operation, companies must accurately understand and master the business flow, logistics, information flow and capital flow in the entire link in real time. The flow and changes of these four make these four processes, as well as all links and processes, coordinated and consistent. Only by cooperating with each other can its maximum benefit be brought into play. However, because all links in the movement of actual objects are in a moving and loose state, the direction of information often moves and changes in space and time with actual activities, which affects the availability and sharing of information. RFID technology is a new technology that effectively solves the problems of input/output of various business operation data, control and tracking of business processes, and reduction of error rates in the supply chain management of manipulator parts.
RFID technology has played a significant role in many links in the supply chain of manipulator parts, and its main applications are as follows:
(1) Retail link of robot parts
RFID technology can improve the inventory management of robot parts retailers, realize timely replenishment, improve efficiency, and reduce errors. At the same time, smart tags can monitor the validity period of certain time-sensitive robot parts. The seller can also use the RFID system at the checkout counter. Realize automatic scanning and billing, instead of manual payment methods.
(2) Manipulator parts storage link
In the robotic parts warehouse, RFID technology is the most widely used in the storage of robotic parts and inventory inventory, it can be used to achieve automated storage and retrieval of robotic parts and other operations. In the entire manipulator parts warehouse management, by combining the receiving plan, pickup plan, and shipment plan made by the manipulator parts supply chain planning system with RFID technology, various business operations can be effectively completed, such as specifying the stacking area of manipulator parts , Put on the shelves for replacement manipulator parts, etc. This enhances the accuracy and speed of operations, improves service quality, reduces costs, saves labor and inventory space, and reduces product misplacement, misdelivery, theft, damage, inventory, and shipment errors in the entire robot parts logistics. And so on. Another advantage of RFID technology is to reduce manpower in the inventory of manipulator parts. Using RFID technology to automate the registration of manipulator parts, no manual inspection or barcode scanning is required during inventory, which is faster and more accurate.
(3) Transport link of manipulator parts
In the management of manipulator parts transportation, the manipulator parts and vehicles transported in transit are affixed with RFID tags, for example, the tags are affixed to containers and equipment to complete equipment tracking and control. RFID receiving and forwarding devices are usually installed at some checkpoints of transportation lines (such as gate posts, beside bridge piers, etc.), as well as key locations such as warehouses, stations, docks, and airports. After receiving the RFID tag information, the receiving device uploads it to the communication satellite along with the location of the receiving place, and then sends it to the transportation dispatch center by the satellite to the database.
(4) Robot parts distribution/distribution link
In the robot parts distribution link, the use of RFID technology can greatly accelerate the speed of robot parts distribution and improve the efficiency and accuracy of the picking and distribution process, and can reduce labor and reduce distribution costs. All manipulator parts arriving at the central distribution center are affixed with RFID tags. When entering the central distribution center, the pallet uses a door reader to read the label content on all the boxes on the pallet. The system checks the delivery records of these information to detect possible errors, and then updates the RFID tag to the latest storage location and status of the robot parts. This ensures precise inventory control of manipulator parts, and even knows exactly how many boxes of manipulator parts are currently in transit, the origin and destination of the transfer, and the expected arrival time.
4 Conclusion
This article proposes a set of general analysis frameworks starting with common characteristics, summary analysis of causes, and countermeasures to solve problems, so that RFID technology can contribute to manipulator drawings, parts production management, warehouse management, and supply chain management faster and better. .
