1、 Daily cleaning and basic maintenance

1. Cleaning of the aircraft body and work area
   • After each use, wipe the surface of the body with a clean soft cloth to remove residual rubber, dust, and oil to prevent corrosion.
   • Clean the workbench and surrounding area, keep the environment clean, and avoid debris affecting equipment operation or causing safety hazards.
2. Cleaning of injection head and mold
   • Cleaning of injection headUse specialized cleaning agents or alcohol swabs to wipe the inner wall of the injection head and remove residual cured rubber; If the blockage is severe, a fine needle or a specialized needle can be used to clear it, but it is necessary to avoid damaging the inner wall.
   • mold maintenanceAfter disassembling the mold, clean the rubber debris inside the mold cavity with a soft bristled brush, and then blow it clean with compressed air; When not in use for a long time, apply anti rust oil to prevent rusting.

2、 Regular maintenance of key components

1. Seal inspection and replacement
   • Regularly inspect the sealing rings and gaskets of various parts of the glue injection machine, and replace them immediately if aging, cracking, or deformation is found to prevent glue leakage or hydraulic oil leakage.
   • When replacing seals, choose products that are consistent with the original specifications and apply an appropriate amount of lubricating grease to ensure sealing performance.
2. Hydraulic system maintenance
   • Hydraulic oil inspectionCheck the hydraulic oil level and quality every 3-6 months. Replace the oil if it becomes cloudy, has an odor, or has a decrease in viscosity; When replacing, it is necessary to drain the old oil and clean the fuel tank.
   • filter replacementRegularly replace the hydraulic oil filter and air filter to prevent impurities from entering the system and causing wear.
   • Pipeline inspectionCheck for oil leakage, cracks, or looseness in the hydraulic pipeline, and promptly tighten or replace damaged components.
3. Pneumatic system maintenance
   • Air source treatmentEnsure that the compressed air is dry and oil-free, and regularly discharge the condensed water from the pneumatic triple components (filter, pressure reducing valve, oil mist device).
   • Cylinder inspectionCheck whether there are scratches or leaks on the cylinder piston rod, and replace the sealing ring or cylinder if necessary.

3、 Electrical system inspection and protection

1. Line and interface inspection
   • Regularly check whether the power and control cables are damaged or aged, and whether the connectors are loose; When the insulation layer is found to be cracked or exposed, it needs to be replaced or insulated immediately.
   • Clean the dust inside the electrical control box to prevent short circuits or poor contact.
2. Calibration of sensors and temperature controllers
   • Regularly calibrate temperature and pressure sensors to ensure precise control of injection temperature and pressure.
   • Check whether the heating element (such as electric heating coil) is working properly to avoid rubber coking or insufficient injection due to abnormal temperature.

4、 Safety protection and operating standards

1. Safety device inspection
   • Before each startup, check whether the emergency stop button, safety light barrier, protective door and other safety devices are sensitive and reliable.
   • Ensure that the safety interlock device (such as the equipment not being able to start when the protective door is not closed) is functioning properly.
2. Operation specification training
   • Operators need to undergo professional training, familiarize themselves with equipment operation procedures and emergency response measures.
   • It is strictly prohibited to touch moving parts or perform dangerous operations (such as reaching out to adjust molds) while the equipment is running.

5、 Professional maintenance and record management

1. Regular professional maintenance
   • Invite equipment manufacturers or professional maintenance personnel to conduct comprehensive maintenance every year, including mechanical component wear inspection, hydraulic system pressure testing, electrical system insulation testing, etc.
   • Perform in-depth maintenance on core components such as servo motors and injection pumps, and replace vulnerable parts if necessary.
2. Maintain record management
   • Establish equipment maintenance records, recording the time, content, replaced parts, and fault handling of each maintenance.
   • Predicting component lifespan through data analysis and developing procurement and replacement plans in advance.

6、 Lubrication and rust prevention treatment

1. Maintenance of lubrication parts
   • Regularly apply lubricating grease (such as lithium based grease) to moving parts such as guide rails, screws, and bearings to reduce wear.
   • When the glue injection machine is not used for a long time, key components need to be treated with rust prevention (such as applying rust proof oil or wrapping rust proof film).
2. environmental control
   • Store the equipment in a dry and ventilated room to avoid damp environments that may cause electrical components to become damp or metal parts to rust.
   • After outdoor use, clean the equipment promptly and cover it with rainproof cloth.
