Common Faults and Solutions of Automatic Dispensing Machine

Automatic dispensing machines are indispensable equipment in modern production and are widely used in many industries such as electronics, automobiles and medical care. However, as service time accumulates and working environments change, automatic dispensing machines will inevitably encounter certain malfunctions. This article lists several common malfunctions of automatic dispensing machines and provides corresponding solutions to help users restore normal equipment operation quickly.

I. Reduced Dispensing Accuracy
Reduced dispensing accuracy is one of the common malfunctions of automatic dispensing machines. It may be caused by worn needles, unstable air pressure or changes in glue viscosity.

Solutions:
1. Replace new needles: Regularly replace worn needles to guarantee the precision and stability of the needles.
2. Adjust air pressure: Check the stability of the air pressure source and adjust the air pressure to an appropriate range to ensure uniform and stable glue outflow.
3. Adjust glue viscosity: Select glue with suitable viscosity according to production requirements to achieve optimal dispensing results.

II. Glue Clogging
Glue clogging is another frequent malfunction of automatic dispensing machines, generally manifested as glue failing to flow normally or flowing sluggishly.

Solutions:
1. Clean the needles: Clean needles regularly to remove residual glue and impurities and keep the needles unobstructed.
2. Replace the glue: Replace with new glue if the original glue has solidified due to long-term disuse.
3. Inspect air pressure: Maintain a stable air pressure source to prevent glue clogging caused by insufficient air pressure.

III. Abnormal Equipment Startup
Abnormal equipment startup may present as the automatic dispensing machine failing to start or being unable to operate properly after startup.

Solutions:
1. Check the power supply: Ensure the equipment power supply is properly connected to avoid startup abnormalities stemming from power issues.
2. Inspect the control board: Check whether the control board is damaged or poorly connected; replace or repair it promptly if any faults are found.
3. Examine the sensors: Verify whether the sensors work normally and troubleshoot any malfunctions in a timely manner.

IV. Glue Leakage
Glue leakage is one of the common potential safety hazards of automatic dispensing machines, which may cause equipment damage or contamination of the production environment.

Solutions:
1. Inspect sealing components: Check whether all sealing parts of the equipment are intact, and replace damaged ones in a timely manner.
2. Adjust glue supply volume: Ensure the glue supply is moderate to prevent leakage caused by excessive supply.
3. Conduct regular maintenance: Perform routine maintenance and upkeep on the equipment to guarantee its normal operation and safety.

In summary, various faults are inevitable during the operation of automatic dispensing machines. By learning about common faults and corresponding solutions, operators can quickly restore normal equipment operation and improve production efficiency and product quality. Meanwhile, regular equipment maintenance and upkeep serve as effective measures to prevent malfunctions.
