Operating Specifications

1. Operator requirements：
   • Operators must be familiar with the structure, performance, working principle, and safety operating procedures of the robotic arm, and untrained personnel are strictly prohibited from operating it.
   • Operators must wear personal protective equipment such as safety helmets, protective goggles, and earplugs that comply with national standards.
2. Pre-operation check：
   • Confirm that there are no people in the operating area, remove obstacles and debris in the operating area, and ensure the normal operation of the robotic arm.
   • Check whether there is water or oil entering the electrical control box. If the electrical appliance is damp, do not turn it on, and check whether the power supply voltage meets the requirements and whether the front and rear safety door switches are normal.
   • Confirm that the load and fixture are well connected.
   • Check whether the corresponding load-bearing bolts are loose and whether the equipment is worn or damaged. Do not use systems that have been detected to have wear and damage without ensuring safety.
   • Before use, it is necessary to open the valves of each compressed air pipeline and check whether the air source pressure meets the requirements (recommended 0.5-0.7MPa). The compressed air should not contain oil or moisture.
   • Check if there is any liquid in the filter cup of the pressure reducing valve that exceeds the scale mark, and drain it in a timely manner to prevent contamination of the components.
3. Operation process requirements：
   • The operation of the robotic arm must be carried out by a dedicated person, and unauthorized personnel are strictly prohibited from operating it.
   • During the operation of the robotic arm, the operator must maintain an appropriate distance and is strictly prohibited from bringing their arms or body close to the robotic arm, or placing their body or other objects within the operating range of the robotic arm.
   • It is strictly prohibited to open the protective door or shield without permission, as well as touch the moving parts of the robotic arm.
   • Do not increase the weight of workpieces beyond the rated load capacity of the equipment (see product nameplate).
   • Do not place your hands on the operating parts of the equipment.
   • When operating the system, always pay attention to the workpiece being carried.
   • To move this device, please confirm that there are no people or obstacles on the moving path first.
   • When the equipment is working, please do not lift the load-bearing workpiece above anyone.
   • Do not use this device to lift personnel, and do not allow anyone to hang on the mechanical arm cantilever.
   • When the workpiece is suspended on the robotic arm, it is prohibited to leave it unattended.
   • Do not weld or cut the suspended load-bearing components.

maintenance

1. Daily cleaning and lubrication：
   • Wipe the friction parts such as guide rails and sliders, and add lubricating oil or butter (lithium based grease is recommended).
   • Regularly clean the robot hand belt and guide rail, and add lubricating oil.
2. Component inspection and replacement：
   • Check if the trachea is twisted, if the joints are leaking, and if the air source is stable and dry (humidity<70%).
   • The electrical connection should be firm, and the terminals between the control box and the robotic arm unit should be checked regularly to prevent looseness or poor contact.
   • When adjusting or replacing the mold, it is necessary to turn off the power and release the residual pressure of the robotic arm to avoid accidental operation and injury.
   • Air pressure and sensor inspection: Test whether the negative pressure sensor is normal (alarm when the product is not suctioned), and confirm the function of the fixture magnetic ring switch.
   • Check the tightness of the synchronous belt and adjust it to the appropriate range (too loose can cause slipping, too tight can cause wear).
   • Clean the filter and muffler to ensure smooth air flow.
   • Limit switch detection: Test whether the input/output signals are normal during mechanical and manual operation, and check whether the position of the limit switch is offset.
   • Seal replacement: Replace the cylinder end cover seal ring (recommended every 24 months) to prevent gas leakage.
   • Line inspection: Check whether the wire connectors and plugs are loose to avoid poor contact and faults.
   • Hydraulic buffer: Replace every 1.5 million cycles or 1 year to ensure buffering effect.
   • Electromagnetic valve maintenance: Clean the impurities inside the valve body and check if the coil is burned.
   • Insufficient suction of the fixture: Check if the vacuum generator is blocked or replace the sealing ring.
   • Inconsistent action: Check the lubrication status of the guide rail or recalibrate the position sensor.

Maintenance precautions

1. Preparation before maintenance：
   • Before adjustment or maintenance, the power supply of the robotic arm should be turned off and the residual pressure of the robotic arm should be released.
   • Turn off the power and lock the robotic arm in the shutdown state before maintenance.
2. Maintenance process requirements：
   • Except for nearby switches, poor suction clamps, and solenoid valve faults that can be self repaired, other faults should be repaired by professionally trained personnel, otherwise do not make unauthorized changes.
   • Original parts cannot be replaced or altered arbitrarily to avoid affecting the performance of SCHUNK robotic arms.
   • During the repair process, do not turn on the power or connect the air compressor to the robotic arm.
   • During the adjustment or replacement of the mold, attention should be paid to safety to avoid being hit by the robotic arm.
3. Post repair inspection：
   • After completing adjustments or repairs, ensure that maintenance personnel leave the hazardous work area before conducting a test run.
