As a professional provider of industrial connection solutions, WL has long focused on the automation equipment field, deeply exploring the connection pain points of robotic arms in practical application scenarios. With the rapid development of industrial automation, robotic arms have become the core equipment in intelligent production lines, undertaking tasks such as loading, unloading, assembling and processing. However, the harsh working conditions such as high-frequency movement, large current transmission, complex electromagnetic environment and limited installation space have put forward strict requirements on the stability and reliability of electrical connections. Aiming at this, WL has launched a full-link robotic arm connection solution, covering all functional levels of automated robotic arms, to provide solid connection support for the high-precision and efficient operation of robotic arms.
WL's connection solutions target all functional levels of automated robotic arms, focusing on four core pain points: large current transmission, vibration resistance during high-frequency movement, stable high-precision signals, and adaptation to limited space. Covering the entire link of base power supply, joint drive, signal collection and end communication, with WL's full range of dedicated connectors and wire harnesses as the core carrier, combined with specific practical models, it achieves high reliability, anti-environmental interference and maintainability of connections at all levels, adapts to the stable operation needs of robotic arms under different working conditions, and lays a solid connection foundation for the high-precision and efficient collaborative operation of robotic arms.
Base and Main Power Supply Module
As the first access node for the power supply and signals of the entire robotic arm, the base needs to stably carry the main power supply and transmit basic sensing signals in a vibrating environment. To meet this demand, this module adopts WL's DP21/29 series 2~3-core high-current power connectors. With low contact impedance and a reliable locking structure, it reduces the risks of heat generation and loosening caused by large currents; the chassis sensing signal access selects WL's 3.00mm pitch C3030 series wire-to-wire connectors, which balance current capacity and vibration resistance in a limited space, ensuring the stability of the entire machine's power supply and basic perception from the source.
Power Drive and Joint Movement Module
Each axis joint rotates at high speed for a long time and bends repeatedly, which is prone to connection loosening and fatigue failure. The joint interface adopts WL's M12 series circular waterproof connectors, with IP67 protection and anti-loosening structure to resist vibration and environmental impacts; the high-speed control and synchronous communication of joints select WL's RJ45 8P8C double-ended connection cables, supporting the EtherCAT protocol to ensure low latency of multi-axis collaboration. Combined with WL's customized flexible joint wire harnesses and anti-vibration terminals, it reduces the risks of cable fatigue and poor contact caused by long-term movement.
Signal Collection and Control Processing Module
Encoder and sensor signals are the core of high-precision control, which need to maintain signal integrity and low latency in complex electromagnetic environments. The differential signal transmission of the encoder adopts WL's C4140 series wire-to-board connectors, supporting 100M-level high-speed transmission and effective anti-interference; for industrial vision and high-speed collection scenarios, WL's USB3.0 double-ended wire harnesses are selected to meet high-bandwidth requirements. The inter-board signals inside the controller realize high-density interconnection through WL's 2.54mm board-to-board connectors and double-row female headers, balancing high-speed transmission, system expansion and maintenance.
End Execution and On-site Communication Module
The end and external interfaces have limited space and frequent plugging and unplugging, requiring adaptation to complex industrial environments. The control of the end effector adopts WL's 1.25mm micro wire-to-board connectors and 2.0mm series wire harnesses, which are miniaturized and anti-loosening; the power supply of the end tool selects WL's M12 to single-row plastic shell terminal wire harnesses, combined with heat shrinkage protection to adapt to high-frequency working conditions. On-site communication adopts WL's M12 X-Code Ethernet connectors (PROFINET, IP67) and RJ45 crystal heads, combined with M12 double-ended shielded wire harnesses, to achieve stable and high-speed interconnection with production lines and upper computers.
In the trend of industrial intelligence, the performance requirements of robotic arms are constantly upgrading, and the role of connection components as the "nerve and blood vessels" of equipment is becoming more and more prominent. WL Technology will continue to adhere to the concept of "demand-oriented, technological innovation", deeply integrate into the robotic arm industry chain, continuously optimize product performance and solution efficiency, launch more targeted connection products and solutions, and help more enterprises realize the upgrading of intelligent production. With professional technology and reliable quality, WL is committed to becoming the core partner for the connection of automated robotic arms, escorting the high-quality development of the industrial automation industry.
