What are the daily maintenance work of the tauren injection molding manipulator?
Cleaning work
External cleaning:
After every day's work, the outside of the manipulator should be cleaned first. Wipe the robot arm, fixture and fuselage with a clean soft cloth to remove dust, oil and plastic debris on the surface. Because if these impurities accumulate for a long time, they may enter the machinery and affect the normal operation of the machinery. For example, dust entering the joints may increase the friction, which may lead to the unsmooth movement of the robot arm.
For some corners and gaps that are difficult to wipe, you can use a small cleaning brush or compressed air to clean them. But pay attention to the pressure of compressed air not to be too high, so as not to damage electronic components or make impurities enter deeper parts.
Internal cleaning (regular):
Every once in a while (such as a week or two, depending on the frequency of use), it is necessary to clean the interior of the manipulator. Open the shell of the manipulator (under the condition of power failure and ensuring safety), and focus on cleaning key components such as motor, reducer, screw rod and guide rail.
For motors and reducers, use special cleaning agent and soft cloth to wipe them, so as to remove oil stains and possibly attached metal chips. The screw rod and guide rail need to be wiped with a clean cloth dipped in a small amount of lubricating oil, and at the same time, the dirt and old lubricating oil on them should be removed, and then an appropriate amount of lubricating oil should be reapplied.
Inspection work
Mechanical parts inspection:
Check the connection parts of the robot arm, including screws, nuts and pins, for looseness. Tap these parts lightly with tools or tighten them manually to ensure that they are firm and reliable. If the joint is loose, the robot arm may shake or deviate during the movement, which will affect the grasping and placing accuracy of injection molded parts.
Check the flexibility and range of motion of the moving parts of the robot arm, such as joints. Manually operate the mechanical arm, observe whether each joint can rotate and extend smoothly, and check whether there is jamming, abnormal noise or abnormal resistance. If a problem is found, it may be that the bearing inside the joint is worn, the lubrication is insufficient or foreign objects enter, which needs to be dealt with in time.
Electrical system inspection:
Check the wires and cables of the manipulator for damage, aging or poor contact. Especially in the parts where friction is easy to occur during the movement of the manipulator, such as the connection between the cable and the manipulator. If the wire is damaged, it may lead to short circuit, electrical failure and even damage the whole manipulator system.
Check the working state of each electrical component, such as whether the indicator light is on normally and whether the sensor is sensitive. For example, check whether the sensor on the end fixture can accurately detect the grasping and placing of injection molded parts. If the sensor fails, it may cause the injection molded parts to fall or be placed in the wrong position.
Lubrication work
According to the manual of the manipulator, determine the lubrication period and position. Generally speaking, the joints, screw rods and guide rails of mechanical arms need to be lubricated regularly.
Choose a suitable lubricant, such as high-temperature grease for the manipulator working in high-temperature environment; For general environment, ordinary industrial lubricants or grease may be enough. When lubricating, it is necessary to pay attention to proper daubing to avoid excessive dripping of lubricant on injection molded parts or the ground. Too much lubricant may pollute injection molded parts, affect product quality, and also cause waste and cleaning difficulties.
Functional testing work
Before starting the machine every day, a simple function test is carried out on the manipulator. For example, start the manipulator, let it do a complete cycle of grabbing and placing, and observe whether its action is accurate and smooth. Check whether the positioning accuracy of the robot arm meets the requirements. By placing a marker at the target position, the robot arm can grab it and place it at the marked position to see if it can overlap accurately.
Test whether the clamping and loosening functions of the fixture are normal. You can check whether the fixture can firmly grasp the injection molded parts and can be released smoothly when necessary by manually operating the fixture or setting up an automatic test program. If there is a problem with the function of the fixture, it may be necessary to adjust the clamping force of the fixture or check the mechanical structure and sensor of the fixture.
