Description

Technical Field

[0001] The utility model relates to the field of medical technology, in particular to a surgical instrument RFID chip welding device. Background Art

[0002] In the medical field, radio frequency identification (RFID) technology has been gradually introduced in recent years to improve the management and tracking efficiency of surgical instruments and ensure their safe and hygienic use. RFID chips can be embedded in or attached to surgical instruments, uniquely identifying and reading the instruments through wireless communication. This greatly simplifies processes such as inventory management, usage records, and sterilization traceability. To ensure the stability and durability of the connection between the RFID chip and the surgical instrument, welding technology has become a key step in achieving this goal.

[0003] Currently, the primary welding method on the market is laser welding. Its non-contact operation, high-precision positioning, and strong material adaptability make it the preferred solution for connecting RFID chips to metal surgical instruments. However, a significant problem with existing welding processes is that they typically use a single laser welding head to weld each component individually. While this method ensures weld quality, it is significantly inefficient for large-scale production, making it difficult to meet the demands of efficient and rapid production. Therefore, improving the production efficiency of RFID chip welding has become a pressing issue in current technological development. Utility Model Content
