- The Pneumatic Industrial Manipulator is not a tool that can be "grabbed and used". It must be completed before starting work.Equipment structure, fixture principle, allowable range and exception handlingtraining.
- The standard operation is divided into eight steps:Approach → Clamp → Confirm → Lift → Translate → Descend → Release → Reset, at least one complete handling cycle should be completed during training.
- You must remember the prohibited operations: overloading, diagonal lifting, impact, entering the danger zone, rapid arm swing, lifting without clamping, and adjusting the air pressure and tooling units without permission.
- Qualification of the training is not based on "listening to the explanation", but must be able toIndependently complete a complete, smooth, and non-dangerous moveAnd handle common exceptions correctly.
Pneumatic Industrial Manipulator are often used in workshop material handling, loading and unloading, and assembly and transfer stations, which can significantly reduce the intensity of manual handling and improve handling stability. But for new employees who are coming into contact with equipment for the first time, the Pneumatic Industrial Manipulator is not a tool that can be "grabbed and used". Before taking up the job, you must complete necessary training and understand the equipment structure, clamping principles, allowable handling range, and exception handling methods before you can enter formal operations. This article summarizes the key contents that new employees should master before using it for the first time, and attaches a first-time training confirmation checklist, which can be used as a basic reference for companies to carry out handling equipment operation training.
01First understand the basic components of the equipment
Before new employees take up the job, they should be able to point out and explain the main components and functions of the Pneumatic Industrial Manipulator:
- Column: The supporting foundation of equipment, usually fixed to the ground, base or track structure.
- Main arm / jib: Responsible for achieving rotation, extension and translation within a certain range.
- joint: Connect each arm segment to enable the manipulator to move within the specified range.
- cylinder: The core execution component of the Pneumatic Industrial Manipulator, responsible for balancing, lifting or auxiliary actions.
- Tooling: Direct contact with the workpiece, which may be clamps, suction cups, clamps, inner supports, magnetic suction or non-standard combination fixtures.
- control handle: The position where the operator issues instructions such as clamping, lifting, lowering, and releasing.
- Air supply system: Including compressed-air supply interface, filter pressure reducing valve, air hose, joints and pressure gauge, which directly affects the stability of the action.
02Clarify the scope of workpieces allowed to be transported
Before using it for the first time, you must confirm "what can and cannot be moved" with this equipment. Each Pneumatic Industrial Manipulator has a design load and applicable workpiece range, which cannot be estimated based on experience.
- Look at the weight: The weight of the workpiece must be within the rated load of the equipment and the allowable load of the fixture. Overloading is strictly prohibited.
- Look at the size: Workpieces that are too long, too wide or irregularly shaped, even if the weight does not exceed the standard, may cause risks due to swinging, unbalanced loading or blocking of sight.
- focus: When the center of gravity of the workpiece deviates, the clamp will receive uneven force and may tilt, slip or rotate after lifting.
- Look at the surface state: For vacuum gripping clamps, pay attention to whether the surface is smooth, clean, dry, and whether there is oil, dust, holes or uneven textures; for claw clamps, pay attention to whether the clamping position has sufficient strength and whether the product will be crushed or empty.
This part is the core of the precautions for using the clamp. For custom tooling, training personnel should demonstrate the correct clamping positions based on real workpieces on site, and clearly indicate which positions are prohibited from clamping.
03Check before starting: the first step for safe operation
The safe operation of Pneumatic Industrial Manipulators starts with inspection before starting up. It is recommended that the operator complete a basic inspection before each shift is used, and that the shift leader or equipment administrator review regularly:
- Check whether the air pressure is within the specified range - if the pressure is too low, it may not be clamped firmly or the lift may be weak, and if the pressure is too high, it may move too fast or damage the components.
- Check whether the pneumatic tubing is bent, aged, worn or leaking, and whether the joints are loose.
- Check whether the clamp structure is firm and whether bolts, pins, and buckles are missing or loose.
- Use the suction cup fixture to check whether the suction cup is damaged, deformed, or aged, and whether the vacuum pipeline is leaking.
- Check whether the limit device is effective and whether there are any obstacles within the action range of the manipulator.
- Confirm that the emergency stop button is in an operable position and that employees know how to use it.
- If the equipment has air supply processing components, check the water accumulation in the filter cup, the status of the lubricator and the pressure gauge reading.
04Operate according to standard procedures and do not rely on free exploration
The use of Pneumatic Industrial Manipulators should be trained according to a fixed process. The standard process can be divided into eight steps:
- Step One · Approach the Workpiece: Stand in a safe position and slowly push the manipulator close to the workpiece to avoid collision with peripheral equipment and personnel.
- Second Step · Grip: Align the clamp at the designated clamping position to ensure that the clamping jaws, suction cups or positioning surfaces are in full contact with the workpiece.
- Third Step · Confirm: After clamping, observe the clamping, vacuum gripping or indication status to confirm that the workpiece is not deflected, clamped in the air or only clamped to the edge.
- Step Four · Lifting: Lift slowly, leave the table or pallet a small height first, and then continue to lift after confirming it is stable.
- Step Five · Horizontal Travel: Keep moving at a steady speed, without pushing hard, swinging arms, or turning suddenly.
- Step Six · Descend: After approaching the placement position, slowly descend to prevent crushing of the workpiece, tooling or hands.
- Step Seven · Release: After confirming that the workpiece has been stably positioned, release the clamp or release the vacuum.
- Eighth Step · Reset: Return the manipulator to the specified parking position and do not hang it in the passage or above the head of the person.
During training, it is recommended that employees complete at least one complete handling cycle, and that the team leader observes whether the movements are consistent and whether there are any dangerous habits.
05Prohibited operations that must be remembered
New employees must know what actions they must not do:
- Overloading is prohibited: Do not handle workpieces that exceed the weight, size, or clamping range.
- Clamping and hanging are prohibited: Do not use the manipulator to drag the stuck workpiece.
- Impact operation is prohibited: Do not hit the workpiece, material rack or equipment with the clamp.
- Personnel are prohibited from entering dangerous areas: No one is allowed to stand under the workpiece, within the movement path or within the rotation area.
- Rapid arm swinging is prohibited: Especially when the workpiece is suspended, sudden acceleration, emergency stop or large-angle swing.
- It is prohibited to lift without clamping firmly.: If you find that the vacuum gripping is unstable or the clamping is skewed, you should put it back immediately.
- Private adjustments are prohibited: Adjustments to air pressure, limiters, balance valves, throttle valves or fixture structures should be completed by the equipment administrator or factory engineering personnel.
These prohibitions should be posted near workstations and included in daily safety inspections.
06On-site handling methods for common abnormalities
Exception handling ability is an important part of judging whether training is qualified:
- Loss of air or significant drop in air pressure: Stop transporting immediately, keep personnel away from the workpiece, place the workpiece safely according to equipment requirements or wait for maintenance personnel to handle it.
- vacuum gripping is unstable: Do not continue to lift, put the workpiece back to its original position, and check the suction cup, workpiece surface condition and compressed-air supply.
- Workpiece slides: Do not lift it directly with your hands. You should first lower the height, stop moving, and notify the team leader.
- manipulator stuck: Do not pull forcefully. Check whether the limit is hit, whether the air hoses is entangled, and whether the joints are blocked.
- Abnormal noise / air leakage / sudden fast and slow movements / automatic drift: Stop the machine immediately and report for repair.
- Dangerous trends emerging: The operator should be able to press the emergency stop correctly and know how to report, isolate and recover after the emergency stop.
07Ergonomics and safe positioning
The value of a Pneumatic Industrial Manipulator is to reduce physical burden, but incorrect positioning can bring new risks. The operator should stand on the side of the workpiece or in a position where it is convenient to exert force through the control handle. Avoid standing directly under the workpiece, or in a position where the workpiece, manipulator, or material rack may be caught. Hands should hold the control handle or the specified handle and should not extend into the clamping surface, the workpiece landing point or near the rotating joint. The line of sight should be able to observe the workpiece, fixture and placement position at the same time, and adjust the position if necessary, rather than operating blindly.
Keep a safe distance from peripheral equipment, aisles, material frames, columns and other personnel. When multiple people collaborate, it should be clear that one person is the main operator, and other personnel are not allowed to push or pull the workpiece or the manipulator at the same time. For larger workpieces, the moving path should be planned in advance and the path should be confirmed to be obstacle-free before moving.
08Shift handover inspection and daily inspection
When handing over a shift, the previous shift should explain the operating status of the equipment, whether any abnormalities have occurred, whether fixtures have been replaced, and whether there are any unresolved maintenance matters; the next shift should confirm the air pressure, pneumatic tubing, joints, tooling units, suction cups, limits, emergency stops, bolts and overall operating status according to the inspection list.
Routine inspections are not just about filling out forms, but also about discovering risks in advance. Equipment managers should regularly check key fasteners, joint wear, compressed-air supply quality, fixture positioning parts and safety signs; safety officers can incorporate training, safe operation requirements and abnormal handling into team safety activities to form continuous improvement.

10Criteria for judging qualified training
After new employees complete training, they should not just use "listening to the explanation" as the qualification criterion. It is recommended to comprehensively judge from the following aspects: be able to independently explain the main components of the equipment and the function of the clamp; be able to judge whether the current workpiece is within the allowed handling range; be able to complete a complete, smooth, and non-dangerous movement handling cycle; be able to actively confirm whether the workpiece is stable after clamping; be able to name at least five prohibited operations; be able to identify common abnormalities such as unstable vacuum gripping, workpiece sliding, abnormal noise, and drift; be able to correctly use emergency stops and understand the reporting process after shutdown; be able to complete pre-start inspections and handover inspections as required.
When encountering new work stations, new fixtures or new products, it is recommended to conduct targeted training again. Only by allowing operators to truly understand the relationship between equipment, workpieces and fixtures can the Pneumatic Industrial Manipulator function safely, stably and for a long time in the workshop.
