Motor motor automatic screwing machine how to carry out maintenance?
1、Routine maintenance
l Cleaning
Body cleaning: After the end of each day's work, use a clean soft cloth to wipe the body of the automatic screwing machine, clear off the surface of the dust, oil and other debris. For parts that are difficult to clean, such as the screw conveyor rail and arm joints, you can use a small brush or compressed air to clean.
Internal cleaning: open the equipment shell regularly (once a week is recommended) to clean the dust inside. Focus on cleaning critical components such as motors, sensors, control circuit boards, etc., as dust accumulation may affect electrical performance and heat dissipation. Use a vacuum cleaner or hair dryer (cold air setting) to carefully remove the dust to avoid damaging the components.
l Checking the screw conveying system
Track inspection: Check whether the screw conveying track is smooth, with no screws jammed or debris blocked. If the screws are found to be jammed, use a special tool to take them out and check the reasons for jamming, such as deformation of the track, inconsistent screw size, etc. At the same time, make sure that the connection parts of the track are tight, with no looseness or gaps, to prevent the screws from falling off in the conveying process.
Vibrating plate inspection: Observe the vibration of the vibrating plate and check whether the vibration frequency and amplitude are normal. If the vibration is abnormal, it may cause the screws to be conveyed unsmoothly. Check the stock of screws in the vibrating disk to avoid too many or too few screws affecting the conveying effect. In addition, clean the dust and oil on the surface of the vibration plate to keep it in good working condition.
l Check the mechanical parts
Mechanical arm inspection: Check whether the movement of the mechanical arm is flexible, whether there is any jamming or abnormal sound. Move the mechanical arm manually and feel whether the resistance of each joint is even. Check the connection parts of the mechanical arm, such as whether the screws are loose, whether the coupling is tight. If the movement of the robotic arm is found to be imprecise, it may need to be calibrated or adjusted.
Fixture check: Check whether the clamping force of the fixture is normal, and whether the jaws can securely hold the workpiece. Check the positioning accuracy of the fixture to ensure that it can accurately position the workpiece so that screws can be screwed in accurately. For the worn clamping jaws or positioning parts, they should be replaced in time to ensure the reliability of the fixture.
l Check the electrical system
Plugs and sockets check: Check whether all plugs and sockets on the equipment are firmly connected, with no loose, oxidized or corroded phenomenon. For loose plugs, re-insert them tightly; for oxidized or corroded plugs and sockets, you can use professional cleaners to clean them and apply the appropriate amount of conductive paste.
Wire Inspection: Look for signs of broken, aged or short-circuited wires. Pay special attention to checking frequently moving parts (e.g., the wire connection part of the robotic arm), as the wires in these parts are prone to wear and tear. If problems are found with the wires, they should be replaced or repaired in time to avoid electrical failure.
2、Regular maintenance
l Lubrication of mechanical parts
Determine the lubrication points: Identify the mechanical parts of the equipment that need lubrication, such as the joints of the mechanical arm, the drive screws, the bearings, etc.. Different parts may need different types of lubricants, for example, the joint parts may need grease, while the screw can use lubricating oil.
Regular lubrication: According to the frequency of use and working environment of the equipment, a reasonable lubrication cycle should be established. Generally, lubricate every certain number of hours of operation (e.g., 500 - 1000 hours) or every other period of time (e.g., one month). When lubricating, apply the appropriate amount of lubricant to avoid excessive lubricant overflow causing contamination or affecting the work of other parts.
l Calibration and Accuracy Adjustment
Mechanical arm calibration: Regularly (quarterly is recommended) calibrate the mechanical arm to ensure its movement accuracy. Use professional calibration tools and equipment, such as laser tracker or high-precision gauges, to check the positioning accuracy and repeat positioning accuracy of the robotic arm. According to the calibration results, adjust the parameters of the robotic arm, such as the zero position of the motor encoder and the joint angle compensation.
Sensor calibration: Regularly calibrate various sensors (such as photoelectric sensors, torque sensors, etc.) to ensure their measurement accuracy. Follow the calibration methods of the sensors and equipment instructions, e.g., use a standard calibration block or a tool with known torque to calibrate the torque sensor. After calibration, record the calibration data for subsequent tracking of changes in sensor performance.
l Software System Maintenance
Software update: Update the control software of the automatic screwing machine in time to get new functions, fix software bugs and improve the stability of the system. Pay attention to the official website or notification of the software supplier and follow the update steps provided by it to update the software. Before updating, backup important equipment parameters and working data in case of problems during the updating process.
Data backup and cleanup: Backup the working data of the equipment regularly, such as screw tightening records, equipment operation parameters, etc. At the same time, clean up the useless data in the software system, such as expired log files, temporary files, etc., in order to free up storage space and improve the operating efficiency of the software.
3、Maintenance after long-term idling
l Equipment cleaning and inspection
After a long period of inactivity, more dust and dirt may accumulate on the surface of the equipment. First carry out all the cleaning work, including the body and internal parts. After cleaning, carefully inspect all parts of the equipment to see if any parts are damaged, deformed or rusted.
l Functional testing and commissioning
Before re-activating the equipment, carry out a functional test. First, run the equipment with no load to check whether the movement of the robotic arm, the work of the screw conveying system and the operation of the electrical system are normal. Then simulate the screwing operation to check whether each function can work together normally. If problems are found, debug and repair accordingly according to the nature of the problem.
l Lubrication and anti-rust treatment
For mechanical parts that have been unused for a long time, even if they have been lubricated before, the lubricant may dry up. Therefore, it is necessary to re-lubricate them. Meanwhile, for metal parts that are easy to rust, such as screws and screw rods, you can apply appropriate amount of anti-rust oil to prevent rust from affecting the performance of the equipment.
