Applications and Technological Optimization of Delta Robots in the Packing Industry

Delta robots, with their high speed and precision, have been widely applied in industries such as food, healthcare, daily chemicals, 3C (computer, communication, and consumer electronics), logistics, semiconductors, and new energy. Particularly in the packing and boxing sectors, delta robots have become one of the most common applications due to their excellent picking and placement capabilities.


Core Advantages of deltas

The core advantages of delta robots are typically reflected in their high speed and high precision. In some precision pick-and-place applications, the robot's speed can reach 120-130 items per minute (according to BAT360-S1, with a 0.1kg payload under the international standard trajectory (25-305-25), achieving a maximum cycle rate of 240 cycles/min, and repeat positioning accuracy of ±0.05mm). The repeat positioning accuracy can be controlled within ±0.06mm. Combined with visual and dynamic picking systems, the accuracy can typically reach ±0.1mm (though this data might not have been tested, and precision may not always meet this level). This high speed and high precision performance is particularly suitable for high-demand automated packaging tasks.


However, in the packing sector, the demand for speed is not as urgent as in other high-frequency picking applications. Packing speed usually depends on the material conveying speed of the upstream production line and the efficiency of the unpacking machine. Therefore, the packing process does not need to pursue extreme speed as required in other applications. In fact, for delta robots in packing scenarios, accuracy and depth control are much more critical.


Requirements in the Packing Sector: Accuracy and Depth

Through industry research and communication with customers, we found that in the packing sector, customers are more concerned with whether the delta robot can effectively "reach" into the box. Traditional packing methods may involve casually throwing items into the box, while delta robots can precisely place items at the bottom of the box. This precise operation not only enhances the neatness of the packaging but also reduces damage during transportation, improving product quality.


Diversity in Delta Robot Designs

Our Robotphoenix’s delta robot product series covers a range of workspace radii, from 250mm to 2000mm, with specific models including: Bat250, Bat360, Bat400, Bat600, Bat800, Bat1100, Bat1300, Bat1600, and Bat2000. Each model has unique working characteristics, and different working spaces offer various applications and advantages. Among them, robots with larger workspace radii offer higher flexibility in terms of depth and packing operations. Smaller-radius robots, on the other hand, have advantages in precision and speed.

According to the specific requirements of packing tasks, the robot’s horizontal and vertical working ranges also vary. Our delta robots can meet most packing application scenarios. The lengths of the robot's upper and lower arms may differ, providing high adaptability under various working conditions. However, customers often have specific depth requirements in practical applications, necessitating further optimization of the existing standard robots to achieve more precise packing results.


Challenges in Cost and Customization

From a production perspective, designing a delta robot with depth-reaching capability is not particularly difficult. As a leading company in the automation sector, we can offer non-standard customization to tailor robots to meet specific customer requirements. However, non-standard custom products are typically not mass-produced, meaning they have longer production cycles and relatively higher costs. Therefore, how to meet the customer's requirements for depth and precision without increasing additional costs has become a key consideration.


Innovative Optimization Plan: Clever Adjustments to Existing Designs

To meet customer needs while reducing production costs, we have innovatively optimized the platform based on existing standard robot designs. We referred to the design of Bat1300 static platform and combined the upper arm of Bat1600 robot with the lower arm of the Bat1300 robot, adjusting the length of the top side of the quadrilateral symmetric structure to further optimize the robot's working range and accuracy. This structural adjustment effectively reduces the edge angles, increasing the robot's vertical working range, allowing the robot to reach deeper into the box under extreme working conditions, and thus complete more precise packing tasks.


The advantage of this optimization plan lies in relying entirely on existing mechanical components, avoiding the high costs of non-standard custom parts. This not only greatly reduces production costs but also shortens delivery times, enabling customers to obtain high-performance robots that meet their requirements without additional costs.


Balancing Performance and Requirements: Trade-off Between Speed and Precision

It is worth noting that although this design sacrifices the delta robot’s advantage in high-speed operations, the speed demand in packing applications is relatively low. As a result, this design can still meet the speed and precision requirements of most packing scenarios. The key factors in the packing process focus more on the accurate placement of products, the neatness of the packaging, and minimizing damage. The new delta robot performs excellently in these aspects.


Looking Ahead: The Vast Prospects of Delta Robots in the Packaging Industry

With the continuous development of smart manufacturing, the application of automation technology in the packaging industry will become increasingly widespread, especially in sectors like food, daily chemicals, and consumer goods, where the demand for automated packing solutions is growing. According to market research, the global industrial robot market is g

rowing at an annual rate of about 15%, with packaging automation, particularly in the packing process, becoming a key growth point in the industrial robot application market.

Delta robots, as highly integrated and precise automation tools, can provide stable and efficient solutions on high-speed packaging production lines with their rigid structures, precise control, and high-speed response capabilities. In the future, as more intelligent algorithms and visual recognition technologies are integrated, robots will demonstrate greater flexibility and adaptability in more complex application scenarios.
