      What are the 8 main maintenance points for an injection molding manipulator?

      Today, we introduce the main points on the maintenance of the mechanical hand of the injection molding machine and let you know more about the maintenance of the mechanical hand of the injection molding machine.

      From the maintenance of long term operation, the injection molding manipulator always pays attention to some important operating conditions which will reduce the downtime and reduce the cost. The following are several issues to be paid attention to:

      1, guide and bearing

      The guideways and bearings at all axes should be kept clean and good lubricity. If the manipulator runs in a dusty environment, it is necessary to clean up the guideway regularly. If you find any metal fragments or powder, it may indicate that the lubrication is not good. In order to ensure proper lubrication, it is very important to have an appropriate linear guidance system. Most of the manipulator have automatic lubrication system and parts that need regular replacement.

      2. The cycle cycle of the manipulator

      One of the main points of keeping the manipulator running well is simple observation and listening, which can expose a lot of information about the overall operation of the manipulator. The manipulator works through specific actions, so listen to any abnormal voice, such as whistling, clicking, etc. these indicate that the bearing cannot rotate properly or some other member is stuck. The link part of the manipulator moves along the guide rail equipped with a power cable and a vacuum hose, making a normal tick, but the sound is smooth and stable. Check any bearings that can be observed to ensure that they are rotated smoothly. Only to check and listen to some signs of wear or need to adjust, can greatly help to maintain the best operating state of the manipulator.

      3. Drive system

      If the manipulator is driven by an assembly - drive gear, notice whether there is any hesitation or sloshing during the operation. All movements in addition to smooth and smooth movements can indicate the damage of the drive system or the internal storage of some foreign objects. When the manipulator moves downward, it is a quick way to check the action or backlash between the assembly beam and the transmission gear. The method is to push the towing arm and feel the abnormal motion. However, due to the high tolerance of normal manufacturers, this method will be very inaccurate. If you suspect that the assembly beam and the transmission gear may have problems, the better way is to use a long range of magnetic pedestal. After adjusting the tooth clearance according to the manufacturer's instructions, check all the stroke of the shaft to ensure that there is no tight place between the assembly beam and the transmission gear. If the gap can not be adjusted, the assembly and transmission gear may wear out and need to be replaced. If it is necessary to repair the assembly and transmission gear, it is best to replace two components at the same time so as to ensure the long-term performance. As for a shaft driven by a conveyor belt, close attention is paid to the debris of the conveyor belt worn down and the damage itself. Check the pulley carefully and notice the signs of dust from the source of the material. Make sure that the conveyor belt and the drive pulley and the grooved pulley are completely arranged in line. The conveyer belt that deviates from the direction will wear out very quickly. As long as it is a belt driven system, the preload of the conveyor belt itself can be checked in accordance with the manufacturer's instructions. These specifications will tell you the appropriate amount of error in the specific position of the conveyor belt relative to the pulley.

      4. Pneumatic system

      Including the multi axial servo drive, almost all the manipulator will have pneumatic function as long as it has the wrist and vacuum grab. Pay close attention to the suction plate of the filter pressure regulating valve unit, where the accumulation of water indicates that the humidity of the compressed air source is too large. The existence of a small amount of water vapor may be transmitted to pneumatic valves and actuators, resulting in oxidation and internal pollution, which may eventually lead to pressure regulating valve sticking or actuator sticking or failure. If the suction disc is equipped with an automatic dehumidifier, the contamination or discoloration on the sucker also indicates that the water gas is increased before it is removed. If the water is gathered in a sucker, it can also enter the system and cause the above problems, even if it has a short time. If you notice any tangible damage to the pneumatic hose, the system may be leaked.

      If the pressure loop is filled with air at normal operating pressure, and leakage in the loop somewhere, then you should easily find obvious hiss, and help you determine the location of the leak.

      5. Check the molding equipment

      The standard configuration of the manipulator is usually installed on the formwork of the molding equipment. When the equipment is running quickly, the vibration from the molding equipment may be transferred to the manipulator and can cause damage. Simply observe the operation of the molding equipment, ensure that the mold movement is adjusted to a reasonable state, reduce the number of shaking or vibration, and extend the life of the manipulator. In high speed operation, the vibration frequency may be very high. It is best to install the manipulator on the supporting structure independent of the molding equipment.

      6. Pay attention to wear line wear

      When examining the surface of a mechanical watch, if a black particle or powder is found, it indicates a sign of wear on the wiring line of the manipulator. However, even if you can't find these wear signals, carefully inspected all power transformer or encoder cables, wiring path on both sides can also, because in the production cycle, continuous line friction of the manipulator, or connected to the cable on the rail line will eventually wear and failure. Ensure the safety of the wiring and belt, as well as the reasonable installation of the cable.

      7. Check lubrication

      The manipulator uses a spring loaded lubricating rod. Unless there is evidence that the guide rail is not lubricated sufficiently, it will only need to be replaced once a year. Configure the automatic lubrication system to follow the machine

      8, vacuum hand grip loop

      The vacuum should be close to the instantaneous formation, and the appropriate input of the controller should be equivalent to the capture of the product. If you find the vacuum is opened, then the input light source will appear, and the delay time is more than 2 seconds. Then it indicates that there are vacuum pipeline leakage, defects or improper adjustment of the switching device. It can be easily tested by the external main control panel. If the manipulator is equipped with a digital vacuum switching unit, the minimum threshold of the vacuum required for the product can be quickly and automatically trimming. The process can be completed in the automatic operation mode of the manipulator. Save the set parameters of each production cycle in the memory, which can save time during the next production change. There are two other advantages of the digital vacuum switching device: the capture of the threshold signal electronic filter makes up for the vibration of the products on the vacuum sucker during the fast motion. The release threshold of the product is different from the capture threshold, and can be programmed, which can guarantee the proper release under the condition of rapid production cycle.
