1、 Preparation before operation

1. environment check
   • Temperature and Humidity ControlEnsure that the laboratory temperature is between 15-30 ℃ and the humidity is ≤ 65% to avoid material deformation or equipment short circuit caused by high temperature and humidity.
   • Ventilation requirementsIf organic solvents or high temperatures produce harmful gases (such as glue evaporation), the ventilation system should be turned on to prevent personnel poisoning or equipment corrosion.
   • Clean environmentRemove debris around the workbench and equipment to prevent dust or particulate matter from contaminating the material surface.
2. Equipment inspection
   • Power supply and groundingCheck whether the power supply voltage matches the equipment requirements (such as 220V/50Hz), and confirm that the grounding is good to prevent leakage and electric shock.
   • Heating system testingAfter starting up, preheat for 10-15 minutes and observe whether the temperature of the heating plate rises uniformly (which can be verified by an infrared thermometer) to avoid local overheating.
   • Pressure system calibrationCheck if the pressure gauge reading is accurate, manually adjust the pressure valve to confirm stable pressure output, and avoid pressure fluctuations during the fitting process.
3. Material Preparation
   • size matchingEnsure that the size of the material to be bonded is smaller than the effective area of the heating plate to avoid warping caused by uneven heating of the edges.
   • Cleaning treatmentDip a dust-free cloth in isopropanol to wipe the surface of the material, remove oil stains, fingerprints, or dust, and improve the bonding strength.
   • Preprocessing (optional)Dry absorbent materials (such as paper and fabric) in a 60 ℃ oven for 1 hour to prevent the formation of bubbles after bonding.

2、 Operation process specification

1. Parameter Settings
   • temperature controlSet the heating temperature according to the material characteristics (such as PET film usually at 120-150 ℃, metal foil may need to be above 200 ℃), to avoid excessive temperature causing material melting or decomposition.
   • stress regulationGradually increase from low pressure (such as 0.1MPa) to the target value (such as 0.5MPa) to prevent material or equipment damage from sudden high pressure.
   • Time SettingThe bonding time needs to be adjusted according to the material thickness and thermal conductivity (such as film bonding usually takes 5-30 seconds), and prolonged bonding time may cause material deformation.
2. Fitting operation
   • Evenly placedPlace the material flat in the center of the heating plate to avoid displacement that may cause uneven heating or stress.
   • Slowly apply pressureAfter starting the device, observe the pressure gauge reading to ensure that the pressure slowly rises to the set value, avoiding impact damage to the material.
   • real-time monitoringMonitor the bonding process through observation windows or temperature pressure curves. If any abnormalities are found (such as sudden temperature rise or pressure fluctuations), immediately stop the equipment and inspect.
3. Cooling and material retrieval
   • natural coolingAfter the bonding is completed, maintain pressure until the material cools to room temperature (usually taking 5-10 minutes) to prevent delamination caused by thermal expansion and contraction.
   • Slowly relieve pressureRelease some pressure first, then turn on the heating plate to avoid material warping due to rapid pressure relief.
   • Gently pick up the materialUse tweezers or specialized tools to remove the fitting, avoiding direct contact with high-temperature surfaces or tearing that may cause material damage.

3、 Safety precautions

1. high-temperature protection
   • Wear protective equipmentWear insulated gloves, goggles, and lab coats during operation to prevent burns or splashes.
   • Warning signSet up "high temperature danger" signs around the heating plate and prohibit unrelated personnel from contacting the equipment.
   • Emergency shutdownFamiliarize yourself with the location of the emergency stop button on the equipment, and immediately cut off the power in case of emergencies such as smoke or odor.
2. Electrical safety
   • Avoid wet operationDo not sprinkle water on the surface of the equipment or operating table to prevent short circuits or electric shock.
   • Regularly inspect the circuitCheck the power cord and heating tube connections for looseness or aging every month, and replace damaged parts in a timely manner.
   • Anti-static measuresFor materials that are prone to static electricity (such as plastic film), grounding discharge should be carried out before operation to avoid static electricity breakdown of equipment or materials.
3. Mechanical safety
   • Prohibit no-load operationAvoid starting the equipment when there is no material or the heating plate is not closed to prevent dry burning of the heating tube or damage to the pressure system.
   • Limit protectionEnsure the sensitivity and reliability of the equipment limit switch to prevent mechanical failure caused by excessive downward pressure on the heating plate.
   • maintenanceClean the residue (such as glue and impurities) on the surface of the heating plate every week to prevent carbon buildup from affecting heat transfer efficiency.

4、 Maintenance and upkeep

1. Daily cleaning
   • Heating plate cleaningUse a dust-free cloth dipped in a small amount of alcohol to wipe the heating plate, avoiding scratching the surface with hard objects.
   • Pressure system cleaningRegularly clean the dust or impurities in the pressure valve and cylinder to ensure stable pressure output.
   • Lubrication of transmission componentsAdd lubricating oil to transmission components such as guide rails and screws every month to reduce wear and noise.
2. periodic calibration
   • temperature calibrationVerify the accuracy of the heating plate temperature using a standard thermometer every quarter, and adjust the temperature controller parameters if the deviation exceeds ± 2 ℃.
   • pressure calibrationCalibrate the pressure gauge reading with a pressure gauge every six months to ensure that the displayed value is consistent with the actual pressure.
   • time calibrationCheck the accuracy of the device timer. If the deviation exceeds ± 1 second, replace the battery or repair it.
3. Fault handling
   • Temperature anomalyIf the temperature of the heating plate cannot rise or fluctuates too much, check whether the heating tube is damaged or whether the temperature controller is faulty.
   • Insufficient pressureIf the pressure cannot reach the set value, check whether the air source pressure, pressure valve or sealing ring is leaking.
   • Poor adhesionIf the material is layered or has bubbles, check whether the temperature, pressure, or time parameters are reasonable, or whether the material surface is clean.
