How to choose a handling manipulator

1. Clarify the handling requirements
Workpiece characteristics: The size, weight, shape, material, etc. of the workpiece directly affect the load capacity, gripping method and range of motion of the manipulator.
Working environment: Factors such as temperature, humidity, dust, etc. in the working environment will affect the material selection and protection measures of the manipulator.
Motion trajectory: The motion trajectory that the robot needs to complete, such as straight line, curve, multi-axis motion, etc., determines the degree of freedom and range of motion of the manipulator.
Accuracy requirements: For workpieces that require high-precision positioning, a high-precision robot needs to be selected.
Cycle time: The production beat requirements determine the movement speed of the manipulator.
2. Selection of robot type
Articulated robot: It has multiple degrees of freedom and high flexibility, and is suitable for the handling of complex workpieces.
Rectangular coordinate robot: It has a simple structure and a clear range of motion, and is suitable for the handling of linear motion.
SCARA type manipulator: It has high speed and high precision on the horizontal plane, and is suitable for high-speed handling in the plane.
Parallel type manipulator: It has a compact structure and good rigidity, and is suitable for high-speed, high-precision, and heavy-load handling.
3. Load capacity
Rated load: The maximum weight that the manipulator can stably handle.
Repeatability: The accuracy of the manipulator to repeatedly reach the same position.
Range of motion: The working space of the manipulator, that is, the range that the manipulator's end effector can reach.
4. Drive mode
Motor drive: Servo motor drive, high precision and high speed.
Pneumatic drive: Simple structure, low cost, but relatively low precision and speed.
Hydraulic drive: Large load capacity, but complex structure and high maintenance cost.
5. Control system
PLC control: Stable and reliable, easy to program.
Servo drive: High control accuracy and fast response speed.
Human-machine interface: Simple operation, easy to set up and maintain.
6. End effector
Vacuum suction cup: Suitable for sucking flat and smooth workpieces.
Mechanical gripper: suitable for grasping irregularly shaped workpieces.
Magnetic suction cup: suitable for grasping ferromagnetic materials.
7. Safety protection
Emergency stop device: stops the operation of the manipulator in an emergency.
Photoelectric protection: prevents personnel from entering the dangerous area by mistake.
Force sensor: detects collision and protects equipment and personnel.
