Overview
In the end-of-line logistics process, the pneumatic balancer is an ideal tool for achieving efficient and accurate palletizing. It fills the gap between manual handling and fully automated robotic palletizing, and is particularly suitable for workstations with limited space, varying product specifications, or requiring manual inspection.
Core Working Principle
Zero-Gravity Balancing: The system senses the load weight in real time and automatically adjusts the air pressure to suspend the workpiece. The operator only needs to apply approximately 2kg to 5kg of force to achieve smooth vertical and horizontal movement.
Customized End-Tackles: Depending on the workpiece shape (e.g., car windshields, engine blocks, cartons, chemical drums, etc.), vacuum suction cups, pneumatic grippers, external expansion lifting devices, or tilting mechanisms can be configured.
High Safety Design:
- Air Supply Interruption Protection: In the event of an accidental air supply interruption, the robotic arm will automatically lock or slowly descend to prevent the workpiece from falling.
- Misoperation Protection: The grippers will only release when the workpiece is fully placed on the support surface, ensuring personnel safety.
Fully Pneumatic Control Logic: No power supply required, excellent explosion-proof performance, suitable for environments with extremely high fire protection requirements such as paint shops and chemical warehouses.
Core parameters
| Performance indicators | Common Range |
| Rated Load | 50kg – 500kg (customizable) |
| Rotation Angle | Horizontal 360° Infinite Rotation |
| Flip Angle | 0° – 180° Powered Flip |
| Power Source | 0.6MPa Clean Compressed Air or 24V/220V Electricity |
Key Functional Advantages:
Stepless Speed Regulation and Fine Adjustment: Because the workpiece is in a balanced state, the operator can move parts weighing hundreds of kilograms as easily as moving small, light objects. This is crucial for precision fits (such as shaft insertion holes and flange connections).
High-Frequency Operation Capability: Fast response time, ideal for production cycles requiring hundreds of handling operations per hour.
Anti-Off-center Load Design: The rigid arm structure not only lifts vertically but also handles workpieces with their center of gravity off-center, ensuring stability during rotation or horizontal movement.
Safety Redundancy System:
Air Supply Interruption Locking: In the event of a sudden air supply interruption, the robotic arm automatically locks to prevent slippage.
Load Detection: When the air pressure is insufficient to support the current load, the system restricts lifting action and issues an alarm.
Typical Application Scenarios:
Machine Tool Loading and Unloading: Precisely placing heavy metal parts and castings into CNC machine tool fixtures.
Warehousing and Logistics: Frequent handling of irregularly shaped bagged materials and drummed chemicals.
Production Line Assembly: Online assembly of car seats, bumpers, and dashboards.
Material Tilting: Achieving 90° or 180° powered tilting with pneumatic fixtures for convenient inspection of both sides of workpieces or for painting.
Customized Fixtures (End-of-Arm Tooling)
Based on your specific workpiece, we can provide:
Mechanical clamps: For shafts, round tubes, or block parts.
Vacuum suction cups: For sheet metal, glass, or cartons.
Internal/external diameter expansion clamps: For coiled or hollow workpieces.
Hook/carryer clamps: For objects with lifting rings or bottom support surfaces.
