Coordinate robots commonly known as "manipulators" are widely used in the field of injection molding and other manufacturing fields to automate production, improve production efficiency and product quality stability, but many companies may lack awareness and expertise in daily maintenance after introducing robots. The following is a special manipulator manufacturer for injection molding machines, Wuxi Saiji Automation Technology Co., Ltd., summarizes some maintenance points for you as follows: Before maintenance work and entering the safe area of the manipulator, please make sure to turn off the main power supply and air pressure source, and remove the air and power connectors. .

1. Daily maintenance of special manipulator for injection molding machine

1. Wipe the guide rail and lubricate;

2. Filter the pressure reducing valve to drain water;

3. Check the pressure of the air pressure source and the dryness of the air;

4. Check whether the negative pressure sensor is normal (whether the product is not inhaled and alarmed);

5. The fixture detects whether the magnetic ring switch is normal (whether the product is not clamped or the material handle is alarmed);

6. Whether the interlock between the manipulator and the injection molding machine is normal (whether the injection molding machine does not lock the mold and alarms when the manipulator is in the manual state).

2. Weekly maintenance of special manipulator

1. Wipe the guide rail and lubricate;

2. Filter the pressure reducing valve to drain water;

3. Check the pressure of the air pressure source and the dryness of the air;

4. Check whether the negative pressure sensor is normal (whether the product is not inhaled and alarmed);

5. The fixture detects whether the magnetic ring switch is normal (whether the product is not clamped or the material handle is alarmed);

6. Whether the interlocking of the special manipulator for the injection molding machine is normal (whether the special manipulator for the injection molding machine does not lock the mold and alarms when the injection molding machine is in the manual state).

7. Check whether the connecting bolts between the special manipulator for the injection molding machine and the injection molding machine are locked and loose;

8. Check whether the setting bolts of each stroke control block are locked or not.

3. Monthly maintenance of special manipulator

1. Check whether the tightness of the timing belt is appropriate;

2. Clean the filter pressure reducing valve and muffler;

3. Readjust the running speed of each action;

4. Check whether the negative pressure sensor is normal (whether the product is not inhaled and alarmed);

5. The fixture detects whether the magnetic ring switch is normal (whether the product is not clamped or the material handle is alarmed);

6. Whether the interlock between the manipulator and the injection molding machine is normal (whether the injection molding machine does not lock the mold and alarms when the manipulator is in the manual state).

7. Check whether the bolts of all moving parts are locked or not;

8. Determine whether the pipeline is broken or whether the wire connection is loose or loose;

9. Wipe the dust and oil on the special manipulator arm of the injection molding machine to ensure that the special manipulator for the injection molding machine is clean;

10. Wipe the oil traces and dust of the special manipulator slide rail and slider of the injection molding machine, and add new lubricating oil;

11. Check the inside of the electric control box: clean the dust, check whether the wiring terminals, relay plugs, and electronic components on the circuit board are loose.

4. Precautions for daily maintenance of special manipulators

The manipulator moves back and forth every day, especially the special manipulator for the injection molding machine moves up and down twice per cycle, and the up and down speed in the mold is very fast, and the upper and lower shock absorption requirements are very high; if the buffer fails, the pneumatic actuator stops when the reciprocating motion is positioned. , There is no shock absorption function, which causes the special manipulator of the injection molding machine to vibrate greatly. Most of the connection parts of the special manipulator for the injection molding machine are fixed by screws. Due to long-term vibration, the screws are loosened and loosened; Due to the vibration of the special manipulator of the injection molding machine, the wire joints are loose and loose, the relay is loose and loose, resulting in poor circuit contact and other phenomena. This leads to the random action of the special manipulator of the injection molding machine, the crash of the electric control, and the burning of the electric control.

 5. The working steps of the full-servo manipulator

1. Oil pressure buffer: This kind of accessories is guaranteed by the supplier for one year or 1.5 million times and needs to be replaced regularly

2. Pneumatic components: The actions of the simple and multi-functional manipulators all rely on the air source to push, and the air source must be stable and fluctuate, and there is no water; because air and water are two different media, gas is invisible, water is visible, and electromagnetic The valve is a precision component. The retention of water in the solenoid, air pipe and cylinder will cause scale, which will cause the reversing solenoid valve to be stuck, gas blowing, air seal wear, air blowing and air leakage, etc. The cylinder will appear weak, crawling, etc. No action or sudden quick action, trachea, joint burst, etc.

3. Replace the cylinder end cover seals, check the air pipes and joints (excluding the servo-driven manipulator) in about 24 months.

4. Regularly check and arrange wire connectors, plugs, sockets, etc. for 12 months.
