Possible Problems and Solutions When Using 3-Axis Robots-Part one

Problem: Fail to suck products occasionally

Reason 1: The air pipe is folded,the air can not go through.
Solution: Dredge the pipe, or replace the damaged pipe.
Reason 2: The air pipe or pipe connector is leaking air.
Solution: Replace the air pipe or pipe connector.
Reason 3: The electromagnetic valve (valve switch) is stucked.
Solution: Check if the wires of the electromagnetic valve are loose, and loose wires cause poor contact of electric.
Reason 4: Opening stroke or thimble stroke is unstable.
Solution: Re-set the pressure and speed of mold opening and thimble. Repair the injection machine if needed.

Problem: Fail to suck products every time

Reason 1: Check if turn on the suck function of robot.
Solution: Check the operation system and enter "suck on ,clip on" into the system.
Reason 2: Vacuum pump or vacuum generator problem.
Solution: Take off the vacuum pump or vacuum generator,check if the Vacuum Pump/ Vacuum generator has adsorption force. Replace the vacuum pump or vacuum generator if needed.
Reason 3: Electromagnetic valve problem.
Solution: Replace the Electromagnetic valve.
Reason 4: The air pipe is folded,the air can not go through the pipe.
Solution: Dredge the pipe, or replace the damaged pipe.

Problem: Alarm even if 3-axis robot successfully suck products, and "suck off" appears on the panel

Reason 1: Vacuum suck wires may loose.
Solution: Check vacuum suck wires.
Reason 2: Negative pressure detection switch is set improperly.
Solution: Follow the instruction to set the parameter. Avoid parameter larger than maximum limit.
Reason 3: Negative pressure detection switch problem.
Solution: Replace the negative pressure detection switch.

Problem: 3-axis robot alarm "arm rotating or back to position on/off"

Reason 1: Alarm "arm rotating or back to position on/off".
Solution: Adjust the position of Reed Switch so that the wires are connected into the sensing area. After adjusting, tighten the screws.
Reason 2: Reed switch of the wrist flip has a problem.
Solution: Replace the reed switch.
Reason 3: Air pressure is too low, don't reach the stadard air pressure.
Solution: Adjust the air pressure, standard 5-7kg.
Reason 4: Wrist flip cylinder is stucke or not working. Rack is attrited.
Solution: Repair or replace the wrist flip.
