In the wave of industrial automation, one process has long relied on manual or semi-automated operations, struggling to balance efficiency and precision — bag and box depalletizing.
Traditional methods are labor-intensive, costly, and unable to handle complex stacking patterns and changing incoming materials. This has made depalletizing a critical bottleneck for automation upgrades. Now, a technology that combines 3D vision and robotic control is transforming this traditional process with breakthrough performance.
01 Project Challenge: Precision Meets Speed
In real industrial environments, depalletizing systems face extremely high performance requirements. They must not only “see,” but "see accurately" and "grasp reliably".
-High precision: Installed several meters above ground, the vision system must overcome angle and lighting interference to achieve ±1 mm positioning accuracy, ensuring the robot locates each picking point precisely.
-High speed: From image capture and calculation to robotic pick, the cycle time must remain within 6 seconds to keep up with consistent production needs.
-Complex stacking: Common pallet patterns like hybrid pinwheel involve varying levels of occlusion and compression between bags, posing major challenges for vision algorithms.
02 Technical Breakthrough: Cutting-Edge 3D Vision System
To address these challenges, an advanced 3D vision system featured Epic Eye Laser L 3D Camera provides a powerful solution by instantly capturing complete 3D point cloud data of the entire stack.
Accurate 3D modeling Unlike 2D vision, 3D vision captures precise depth information. Even with overlapping, reflective, or textureless surfaces, it can reconstruct each bag as a detailed 3D model.
Intelligent algorithmsBuilt-in AI algorithms automatically compute the optimal grasping pose for each bag, guiding the robot’s end-effector to perform accurate picking.
Outstanding performanceProven in real projects, this solution maintains a 99.9% recognition success rate when handling standard plastic film bags, achieving near-perfect picking accuracy.
03 Real-World Application: Driving Smart Upgrades
On a major building materials production line, this intelligent 3D vision depalletizing system has been successfully deployed and operates stably.
Fully automated process: Operators or AGVs only need to place the pallet at the designated position. All subsequent steps—detection, picking, and placing onto the conveyor—are fully automated, realizing true “unmanned” depalletizing.
High adaptability: With strong learning capabilities, the system can quickly adapt to new bag types through sample collection and model training, enhancing production line flexibility.
Significant value: The solution not only frees workers from repetitive, intensive labor but also improves overall line efficiency and reduces long-term operational costs through stable, continuous performance.
From manual judgment to AI vision, from experience-driven to data-driven, 3D vision intelligent depalletizing technology is becoming the key enabler of the “last mile” of industrial automation. With proven performance and reliability, it offers an excellent solution for industries such as chemicals, building materials, food, and logistics to achieve their intelligent transformation goals.
