"Three-minute Integrity Check" Every Day Ensures Smooth & Stable Production Process.

Before starting the screen printing machine, performing a quick and complete inspection procedure is the cornerstone for preventing equipment failure, ensuring operator safety, and guaranteeing the first-piece pass rate. The following "Three-Minute Integrity Check" process, also known as the Four Major Systems check, must be followed to cultivate good production habits:

Step 1: Pneumatic System Check – Ensure Stable Power

1. Confirm Main Air Supply is On: Check that the factory main air supply valve is in the "ON" position.

2. Observe the Air Treatment Unit (Filter, Regulator, Lubricator):

   • Pressure Gauge Reading: Confirm the air pressure value is within the equipment's required range (typically 0.5~0.7 MPa). Adjust if too low or too high.

   • Lubricator Oil Level: Check that the oil level in the lubricator is between the upper and lower limits. Add the specified type of lubricating oil if insufficient.

   • Auto-Drain Function: Press the drain valve at the bottom of the filter to discharge condensate.

3. Listen for Air Leaks: In a static machine state, listen carefully for any obvious "hissing" sounds indicating air leaks.

Step 2: Electrical System Check – Ensure Reliable Control

1. Confirm Main Power is Connected: Check that the equipment's main power switch is closed and the power indicator light is on normally.

2. Check Emergency Stop Buttons: Ensure all emergency stop buttons are in the released (popped-out) state. Otherwise, the machine cannot be powered on.

3. Observe the Control Panel: After powering on, check that the touchscreen or indicator lights display normally, with no abnormal alarm codes.

4. Inspect Cable Connections: Visually inspect main power cables and signal cables for obvious damage, looseness, or disconnection.

Step 3: Transmission and Guide Rail System Check – Ensure Smooth Operation

1. Cleaning and Debris Removal: Use an air gun or soft cloth to clean dust, oil stains, and residual splashed ink from guide rails, lead screws, and transmission belts. Ensure there are no obstructions.

2. Lubrication Status Check: Visually inspect the surfaces of guide rails and lead screws for an even oil film. If dry or rusty, immediately add the specified type of grease or lubricating oil.

3. Manual Movement Test: Gently attempt to push the print head or worktable by hand to feel if the movement is smooth, without sticking or abnormal noises.

Step 4: Safety and Braking System Check – Ensure Personal Safety

1. Function Test Emergency Stop Buttons: While the machine is idling at low speed, try pressing any emergency stop button to confirm the machine immediately stops all movement.

2. Check Safety Guards: Ensure all protective covers and light curtain safety sensors are in place and functioning correctly, without being blocked or displaced.

3. Verify Fixturing Devices: Check that clamps on the printing platform and vacuum suction holes are clean and unobstructed, ensuring they can reliably hold the substrate.

The "Three-Minute Check" is by no means a formality; it is a professional reflection of responsibility towards the equipment, the product, and one's own safety. Adhering to this process can eliminate the vast majority of potential problems at the budding stage, and is the first step towards achieving "Zero Unexpected Downtime" and "High-Quality Output".
