Manipulator Arm, also known as pneumatic balance assist arm, pneumatic balance crane, jib crane, is a novel assistive device used for effortless operation during material handling and installation. It is a pneumatic assisted human power, a mechanical arm operated manually. The use of Manipulator Arms can reduce the labor intensity of operators, achieve lightweight operation and accurate positioning when handling heavy workpieces, and ensure the safety of equipment and operators.
Pneumatic Manipulator Arms Classification
Pneumatic Manipulator Arms are divided into two types: column type and suspension type. The main structure is divided into three main rotary joints, which can rotate 360 °, 300 °, and freely around their own axis. Each joint is equipped with a braking device, which can brake at any position according to actual needs.
Pneumatic Manipulator Arm Structure
① According to Installation ways:
1. Column fixed type
2. Base mobile type
3. Ceiling suspended fixed type
4. Gantry suspended mobile type
5. Wall mounted type
Fixture Types:
It is usually customized based on the external dimensions of the workpiece provided by the customer. Select the R&D design based on the on-site workpiece and working environment, and design the one with the best usage effect. Fixtures generally have 1. Hook type; 2. Grab type; 3. Clamping type; 4. Internal inflation type; 5. Lift type; 6. Clamping type; 7. Gripping flip type (flip 90 degrees or 180 degrees); 8. Vacuum adsorption type; 9. Vacuum adsorption transformation (flipping 90 degrees or 180 degrees) and other methods.
② Safety measures:
1. Equipped with a gas storage tank, it can continue to use one cycle in the event of a gas outage, while also sounding an alarm to remind the operator to activate the self-locking function when the air pressure drops to a certain level to prevent the workpiece from falling off.
2. Joint brake device, with multiple rotary joints to achieve material retrieval over a wide range, equipped with a brake device, allowing the operator to interrupt the movement of the robotic arm at any time during operation
3. Equipped with a load display, indicating the load status and informing the operator whether the material can be lifted or unloaded at this time. When the system is under load, the display turns red.
4. Equipped with a load pressure gauge to indicate the working condition of compressed air.
5. Equipped with safety misoperation protection devices to prevent harm to personnel or equipment caused by misoperation; Before the operator confirms the installation status, that is, before the workpiece is installed in place, if the worker accidentally releases the button, the workpiece cannot be unloaded (limited to power fixtures).
6. The system is equipped with a gas loss protection device. When the main gas supply source is accidentally cut off, the main arm cannot move and the robotic arm stops working to avoid accidental injury.
7. The equipment is equipped with a safety control system. During operation, the system will not suddenly change the load or no-load pressure due to misoperation, so the robotic arm will not cause harm to personnel, equipment, and products due to rapid rise or fall.
