Spider robots (high-speed parallel robots) are renowned for their exceptional speed and acceleration, making them the ideal choice for high-speed pick-and-place applications.
I. Typical Speed Range
| Performance Metric | Typical Value |
|---|---|
| Standard Pick-and-Place Cycle | 0.3 to 0.5 seconds per cycle (including picking, moving, and placing) |
| Maximum Pick Rate | Up to 200 picks per minute or more, depending on part size and travel distance |
| Acceleration | Up to 100 m/s² (10 G) or higher |
| Maximum Travel Speed | Typically up to 10 m/s |
II. Factors Influencing Speed
The actual achievable speed depends on several variables:
Payload: Heavier parts reduce achievable acceleration and speed. Standard ratings are typically for lightweight items (grams to a few hundred grams).
Pick-and-Place Distance / Stroke: Longer travel distances increase cycle time.
Pick Height Variation: Significant Z-axis movement adds time.
Part Presentation: Consistent part orientation and position minimize waiting and search time.
End-Effector Type: Lightweight grippers or suction cups enable higher speeds.
III. Industry Benchmark Examples
| आवेदन | Typical Cycle Time | नोट्स |
|---|---|---|
| Food (e.g., cookies, candies) | 0.3 – 0.5 sec | High-speed packaging lines |
| Pharmaceutical (e.g., vials, blister packs) | 0.4 – 0.6 sec | Gentle handling with precision |
| Electronics (e.g., small components) | 0.3 – 0.5 sec | High precision at speed |
| Lightweight consumer goods | 0.4 – 0.7 sec | Varies with product size |
IV. Comparison with Other Robot Types
| Robot Type | Typical Cycle Time (300mm pick-place) |
|---|---|
| Spider Robot (Delta/Parallel) | 0.3 – 0.5 seconds |
| SCARA Robot | 0.5 – 0.8 seconds |
| 6-Axis Articulated Robot | 0.8 – 1.5 seconds |
Summary: Spider robots are the fastest class of industrial robots for lightweight pick-and-place applications, typically achieving cycle times of 0.3 to 0.5 seconds and pick rates exceeding 200 parts per minute. Their speed advantage comes from their lightweight parallel-link design and high-performance servo drives.
