Selection Guide of Gantry Robot - HYMAT

The selection of a gantry robot is a crucial step that directly impacts its performance and efficiency in practical applications. Below are detailed selection recommendations to help you choose the appropriate gantry robot based on specific needs:

1. Define Requirements

1.1 Task Type:
- Determine the primary tasks of the robot (e.g., material handling, assembly, welding, painting).
- Example: For machine tool loading and unloading, a robot with high precision and stability is required.

1.2 Load Requirements:
- Determine the maximum weight of the workpiece to be handled or manipulated.
- Example: If the workpiece weighs 50kg, select a robot with a load capacity of ≥50kg.

1.3 Working Range:
- Determine the working area (length, width, height) that the robot needs to cover.
- Example: If the working area is 3m×2m×1m, select a robot with matching travel ranges.

1.4 Precision Requirements:
- Determine the positioning accuracy and repeatability based on task requirements.
- Example: Precision assembly tasks may require a repeatability of ±0.05mm.

1.5 Speed Requirements:
- Determine the robot's movement speed based on production efficiency needs.
- Example: High-speed production lines may require robots with fast movement speeds.

2. Key Parameter Selection

2.1 Load Capacity:
- Select the robot's load capacity based on the workpiece weight, with a recommended margin (e.g., 20%).
- Example: For a 50kg workpiece, choose a robot with a load capacity of ≥60kg.

2.2 Travel Range:
- Select the X, Y, and Z-axis travel ranges based on the working area.
- Example: For a 3m×2m×1m working area, choose a robot with X-axis ≥3m, Y-axis ≥2m, and Z-axis ≥1m.

2.3 Precision and Repeatability:
- Select the precision level based on task requirements.
- Example: For precision assembly tasks, choose a robot with a repeatability of ±0.05mm.

2.4 Movement Speed:
- Select the movement speed based on production efficiency needs.
- Example: For high-speed production lines, choose a robot with X/Y-axis speeds of ≥1m/s.

2.5 Degrees of Freedom:
- Select the number of degrees of freedom based on task complexity.
- Example: For simple handling tasks, choose a 3-degree-of-freedom robot (X, Y, Z-axis); for complex tasks, consider adding rotational or gripping functions.

3. Structure and Configuration

3.1 Gantry Material:
- Choose materials with high rigidity and lightweight properties (e.g., aluminum alloy, steel, or carbon fiber).
- Example: For high-load tasks, choose steel structures; for high-speed tasks, choose aluminum alloy or carbon fiber structures.

3.2 Drive Method:
- Select the drive method based on precision and speed requirements (e.g., servo motor + ball screw, rack and pinion, or linear motor).
- Example: For high-precision tasks, choose a servo motor + ball screw drive.

3.3 Control System:
- Choose a high-performance controller (e.g., PLC or industrial computer) that supports multi-axis coordination and complex path planning.
- Example: For complex tasks, choose a control system that supports offline programming and simulation.

3.4 End Effector:
- Select end tools such as grippers, suction cups, or welding torches based on task requirements.
- Example: For handling tasks, choose pneumatic grippers; for welding tasks, choose welding torches.

4. Budget and Cost-Effectiveness

4.1 Budget Range:
- Choose a cost-effective robot within the budget.
- Example: Select a reasonably priced domestic robot that meets the requirements.

4.2 Long-Term Costs:
- Consider the robot's energy consumption, maintenance costs, and lifespan.
- Example: Choose a robot with low energy consumption and simple maintenance to reduce long-term costs.

Summary

The selection of a gantry robot requires comprehensive consideration of task requirements, key parameters, structural configuration, and budget. By clearly defining needs, making reasonable selections, and optimizing configurations, you can ensure that the robot performs optimally in practical applications and meets production demands.
