1. Precautions for daily maintenance of special robotic arms
The manipulator reciprocates every day, especially the special robotic arm of the injection molding machine reciprocates 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 fulfillment element will have no shock absorption function when the reciprocating motion stops positioning, forming a special manipulator for injection molding machines. Most of the joints of the special manipulator for injection molding machines are fixed by screws, because the screws are loose and loose due to long-term sensation; It is bound to form the collapse of the special manipulator for the injection molding machine, and the cracking of the connector block of the parts. Because of the sensation of the special manipulator of the injection molding machine, the wire joints are loose and loose, the relay is loose and loose, and the circuit line is not in good contact. It leads to the phenomenon of disorderly operation of the special manipulator of the injection molding machine, electronically controlled crash, and burning out of the electronic control.
1. Hydraulic buffer: This kind of accessories is guaranteed by the supplier for one year or 1.5 million times, and it is necessary to replace it regularly
2. Pneumatic components: the actions of simple and multi-functional manipulators all depend on the propulsion of the air source, and it is necessary for the air source to be stable, with small fluctuations and no water; Because gas and water are two different media, gas is invisible, water is tangible, solenoid valve is a fine component, water in the electromagnetic, trachea, cylinder retention will produce scale, the formation of reversing solenoid valve stuck, blow-by, gas seal wear, cylinder channeling, leakage, etc., the cylinder action appears weak, creeping, no action or sudden fast action, trachea, joint bursting and other phenomena.
3. About 24 months to replace the cylinder end head seal, check the air pipe, joint (excluding servo drive manipulator).
4. Check and pack up wire connectors, plugs, sockets, etc. regularly for 12 months.
Second, the daily maintenance of the manipulator
1. Scrub the guide rail, smooth;
2. Filter the pressure reducing valve for drainage;
3. Check the pressure of the source of air pressure and the dryness of the air;
4. Check whether the negative pressure sensor is normal (whether the product is alarmed if it is not sucked);
5. The fixture detects whether the magnetic ring switch is normal (whether the product or material handle is not clamped is alarmed);
6. Whether the manipulator and the injection molding machine are interlocked normally (whether the manipulator does not lock the mold and alarm the injection molding machine in the manual condition).
3. Weekly maintenance of special robotic arms
1. Scrub the guide rail, smooth;
2. Filter the pressure reducing valve for drainage;
3. Check the pressure of the source of air pressure and the dryness of the air;
4. Check whether the negative pressure sensor is normal (whether the product is alarmed if it is not sucked);
5. The fixture detects whether the magnetic ring switch is normal (whether the product or material handle is not clamped is alarmed);
6. Whether the interlock of the injection molding machine is normal (whether the injection molding machine does not lock the mold and alarm the injection molding machine in the manual condition of the special manipulator for the injection molding machine).
7. Check whether the connecting bolt between the special manipulator of the injection molding machine and the injection molding machine is tightened and loosened;
8. Check whether the setting bolts of each stroke control block are locked or whether they are loose.
Fourth, the special robotic arm is maintained every month
1. Check whether the tightness of the timing belt is appropriate;
2. Clean the filter pressure reducing valve and silencer;
3. Readjust the running speed of each action;
4. Check whether the negative pressure sensor is normal (whether the product is alarmed if it is not sucked);
5. The fixture detects whether the magnetic ring switch is normal (whether the product or material handle is not clamped is alarmed);
6. Whether the manipulator and the injection molding machine are interlocked normally (whether the manipulator does not lock the mold and alarm the injection molding machine in the manual condition).
7. Check whether the bolts of all moving parts are locked and loose;
8. Determine whether the pipeline is broken or whether the wire connection is loose and loose;
9. Scrub the dust and oil on the special manipulator arm of the injection molding machine to ensure that the special manipulator of the injection molding machine is clean;
10. Scrub the oil stains and dust of the special manipulator slide rail and slider of the injection molding machine, and add new smooth oil;
11. Check the inside of the electric control box: clean the dust and check whether the electronic components on the terminals, relay plugs, and circuit boards are loose and loose.

Universal Robots – an introduction to the features of the robot control system
(1) The control of the robot is closely related to the kinematics and dynamics of the mechanism. The state of the robot hand and foot can be described under various coordinates, and the reference coordinate system should be selected according to the specific needs, and the appropriate coordinate transformation should be done. There is often a need for forward kinematics and anti-kinematics.
