Robotics and Automation

Industry Core: Robotics and automation are the core carriers for the implementation of AI technology, covering humanoid robots, industrial robotic arms, AGV/AMR (Automated Guided Vehicles), intelligent sorting robots, etc. They are widely used in industrial manufacturing, logistics and warehousing, new energy, electronic manufacturing and other fields. The industry has extremely high requirements for the precision, wear resistance, fatigue resistance, and lightweight of hardware components, and the requirements for the size, structure, and force of hardware parts vary greatly among different models and scenarios, with prominent non-standard customization needs.

AI Scenarios: Humanoid robots (joint drive, dexterous hand operation, gait control), industrial robotic arms (multi-axis linkage, high-precision grasping, welding/assembly), AGV/AMR (intelligent navigation, material handling, workshop inspection), intelligent sorting robots (AI visual recognition, rapid sorting, precise positioning), collaborative robots (human-machine collaborative operation, flexible production). These scenarios all require hardware components to achieve precision transmission, reliable connection, and high-frequency motion adaptation, and to adapt to the precise control needs of AI algorithms.

Key Hardware Products: Precision joint bearings (non-standard size joint bearings, wear-resistant bearings), reducer gears (MIM process gears, non-standard tooth profile gears), dexterous gripper structural parts (customized grippers, transmission connecting rods), anti-vibration fasteners (micro locknuts, non-standard bolts), guide rail sliders (high-precision guide rails, customized sliders), brake and clutch hardware (non-standard brake discs, clutch plates, transmission pins). In addition, it also includes robot body structural parts, joint connectors, sensor mounting hardware, AGV wheel axles and other non-standard customized parts.

Core Functions: Achieve multi-degree-of-freedom precision transmission of robot joints to ensure the flexibility and accuracy of motion; bear the impact force of high-frequency reciprocating motion, have high fatigue life, and avoid hardware breakage and wear during motion; achieve reliable connection of various parts of the robot, prevent loosening caused by vibration, and ensure the accurate execution of AI control commands; reduce the overall weight of the robot, achieve lightweight design, and improve motion efficiency and endurance; provide structural protection against wear, vibration, and high and low temperatures, adapting to complex working conditions such as industry and logistics.

Selection Notes & Processing Advantages (Machining/Cold Heading):

1. Micro Precision Connection for Robot Joint Needs: The internal space of robot joints is narrow, requiring extremely high miniaturization and precision of hardware parts, which ordinary standard parts cannot meet the installation and force requirements. Through precision machining equipment such as Swiss-type lathes and multi-axis CNC turning and milling centers, we can process micro non-standard screws with a head diameter of less than 1.0mm and a length of 5-20mm (such as hexagon socket cup head, countersunk hole, special-shaped head screws), with dimensional tolerance controlled within ±0.005mm, achieving precision forming of ultra-long aspect ratio. While ensuring lightweight, it has high torque bearing capacity (torque up to 1-5N·m), perfectly adapting to the joint connection needs of humanoid robots and micro robotic arms. At the same time, we can customize the thread profile and head structure according to the joint force to improve the reliability and adaptability of the connection.

2. High Fatigue Life Structural Parts for High-Frequency Motion: Industrial robotic arms, AGVs and other equipment need to perform high-frequency reciprocating motion for a long time. Hardware structural parts (connecting rods, pins, gears) are prone to fatigue wear and breakage, affecting the service life of the equipment. We use cold heading precision forming technology to manufacture structural parts such as connecting rod pins and gears. The cold heading process can make the material fiber flow continuous, avoiding fiber breakage caused by machining, and the material has excellent toughness, with a fatigue life of more than 10^7 times, far exceeding ordinary cutting parts. For complex tooth profile structures such as reducer gears, a combination of cold heading and machining processes is adopted. First, the tooth profile blank is formed by cold heading, and then the tooth surface is accurately trimmed by machining to ensure the tooth profile accuracy and meshing smoothness, while improving the wear resistance and impact resistance of the gears, adapting to high-frequency motion scenarios.

3. Rapid Response to Modification for Robot Iteration Needs: The AI robot industry has a fast technological iteration speed. The requirements for the size, structure, and force of hardware parts of robots of different models and application scenarios often change. The mold opening and trial production cycle of conventional suppliers is long, which cannot meet the customer's rapid iteration needs. We have the ability of rapid mold opening and process programming. For the customer's design modification needs, we can complete non-standard mold development, process programming and sample trial production within 3-7 days, and achieve mass production within 15-20 days, greatly shortening the cycle of customer production line adjustment and product iteration, and reducing the customer's R&D and production costs. At the same time, we can provide design optimization suggestions, combining the characteristics of machining and cold heading processes to optimize the hardware structure and improve product performance and production efficiency.

4. Balance of Lightweight and High Strength for Robot Endurance: Humanoid robots, AGVs and other mobile robots have extremely high requirements for lightweight, and at the same time need to ensure the high strength of hardware parts to avoid structural deformation during motion. We select lightweight materials such as aluminum-magnesium alloy and high-strength stainless steel, and optimize the structure through machining (such as hollowing, chamfering, thin-walled design). On the premise of ensuring a tensile strength of ≥300MPa, the weight of hardware parts is reduced by more than 30%. For hardware parts in load-bearing parts, high-strength materials are cold-headed, and the size is accurately controlled through machining to achieve a perfect balance between lightweight and high strength, improving the motion efficiency and endurance of the robot.
