Customizable Payload Robotic Arm OEM ODM Service for Special Automation Projects

The YH series industrial robot is a programmable, multifunctional automated machine, mainly used in industrial production environments. It can automatically perform various tasks in three-dimensional space, such as handling, welding, assembly, painting, stacking, and inspection. They are usually composed of a mechanical body, drive system, control system, and sensing system, and have features of high precision, high speed, high reliability, and repeatability. They are core equipment for modern intelligent manufacturing.

Composition of Industrial Robots

1. Mechanical body

These are the "bones" and "muscles" of the robot, the part that directly performs the action.

1.1 Structure: It usually consists of a base, big arm, small arm, wrist and end flange.

1.2 Joints and Degrees of Freedom: Connected by multiple joints (rotating or moving), providing different degrees of freedom (DOF). The six-axis industrial robot has 6 degrees of freedom and simulates the flexibility of a human arm.

1.3 End effector: A tool installed at the end of the wrist that is in direct contact with the object being operated. Such as grippers (pneumatic/electric), suction cups, welding guns, spray guns, grinding heads, laser cutting heads, etc.

2. Drive system

This is the "power source" of industrial robots and is responsible for providing the energy needed for movement of various joints.

2.1 Servo motors: most commonly used, providing high precision and high response position and speed control.

2.2 Hydraulic/Pneumatic Devices: Used in heavy-duty (hydraulic) or simple clamping (pneumatic) scenarios, but less common in high-precision multi-axis robots.

2.3 Reducer: Connects the motor to the joint to reduce the speed, increase torque, and improve positioning accuracy.

Key components: RV reducer (often used for heavy load joints) and harmonic reducer (often used for light load or wrist joints).

3. Control system

This is the "brain" of the robot, which processes information, plans paths, and gives instructions.

3.1 Controller hardware: An industrial computer or a dedicated control cabinet containing CPU, memory, and interface circuits.

3.2 Control Software/Algorithm:

3.2.1 Motion Control: Solve inverse kinematics and plan joint movement trajectories to ensure smoothness and precision.

3.2.2 Logic Control: Process input and output signals (I/O) and coordinate cooperation with other devices (e.g., conveyor belts, sensors).

3.2.3 Human-Machine Interface (HMI): Teach Pendant for operators to program, debug, and monitor robot status.

4. Perception system

This is the "five senses" of the robot, which is used to obtain internal status and external environment information, and is the key to achieving intelligence.

4.1 Internal Sensors:

4.1.2 Encoder: Detect motor angle and speed to achieve closed-loop control.

4.1.3 Torque sensor: detects joint force and is used for collision detection or force control grinding.

4.2 External Sensors:

4.2.1 Vision system: industrial camera, 3D scanner, for positioning, identification, quality inspection.

4.2.2 Force/Tactile Sensors: Mounted at the end for precision assembly or constant force grinding.

4.2.3 Safety sensors: Lidar, safety light curtains, used to monitor surrounding personnel and ensure safe shutdown.

5. Assistive systems

While not a core moving part, it is essential for running:

5.1 Power supply system: power supply unit, voltage regulator.

5.2 Air Circuit System: Provides compressed air to the pneumatic gripper or balance cylinder.

5.3 Cooling System: Fan or water cooling device to prevent overheating of the motor and control cabinet.

5.4 Safety fence and emergency stop button: physical protection that meets safety standards.

Industrial robots have now penetrated almost all manufacturing industries. The core is: to replace humans in performing repetitive, dangerous, and high-precision tasks.
