Antistatic multiplier chain purchase and maintenance Nan

Electronic factory static electricity destroy board frequently? Anti-static multiplier chain procurement to avoid pit 5 strokes, theYield stable 99%+
--Newbie white copy homework, save the cost of return to repair in the yearOver 200,000


First, anti-static grade selection is not correct? Material money is all down the drain!

"Anti-static" ≠ "non-conductive"If you buy the wrong one, it will be a "chip killer" in a minute! Remember the 3 hard indicators:

  1. Surface resistance must be stuck at 10^6-10^9 Ω-cm(Refer to anti-static plastic grading standards) - too high to discharge slowly, too low to directly penetrate the component!
  2. Preferred anti-static wood/reinforced PVC boards for workwear boards(Antistatic rubberised surface), don't use ordinary plywood - the friction voltage easily exceeds 5000V!
  3. Metal parts must be anodisedBare aluminium sprockets discharge like lightning! Bare aluminium sprockets discharge like lightning, the oxide film is the "cushion"!

Blood tears lesson: a factory greedy cheap with ordinary PVC roller, 3 months after the electrostatic breakdown rate soared 15%


Second, the structural design buried a big mine? These 3 cut corners are the most deadly

You think a multiplier chain is just a chain + motor?Hidden pits for newbies::

  • Guide rails must be stainless steel sprayed! Carbon steel rust = grounding failure, aluminium alloy is not strong enough and easy to deform (choose thickness ≥3mm for heavy loads)
  • Two-speed drive verification to be testedThe speed of the work plate should be up to 2.5 times the speed of the chain! The speed of the work plate should be up to 2.5 times of the chain, take the code meter to measure 10 times to take the average value.
  • See here for modular interfaces: Use hexagonal bolts + elastic spacers for bracket connection, disassemble and install 10 times without slipping wire to be qualified.

Third, the drive system to save money = looking for death! Motor so with power saving 30%

Don't be fooled by the "inverter".! The real money-saving configuration looks like this:

  1. Motor power redundancy 20%: 10m line body load 300kg, at least choose 1.5kW motor (formula: power = 0.05 x line length x load)
  2. Reduction gears must be IE3 energy efficient! Save 3 kWh per day, pay back the difference in a year!
  3. Chain TensionerSelf-adjusting tensioning wheels are 500% more expensive than manual screws, but eliminate the need for 2 hours of downtime per month to adjust the chain.

Ask yourself.Q: What if my boss has to buy a used doubler chain?
A: focus on checking three items! ① chain wear ≤ 3% (caliper measurement roller diameter) ② motor insulation resistance > 10MΩ (megohmmeter measurement) ③ guide flatness error <2mm (laser level)


Fourth, routine maintenance laziness? Burn an extra 50,000 per month for maintenance!

Antistatic properties3-month plunge of 50%! These three tricks minimise wear and tear:

▶ Grounding system must be inspected weekly

  • Multimeter measurement chain link - grounding pile resistance <10Ω, exceeding the standard with sandpaper grinding off the paint layer
  • 1MΩ safety resistor monthly measured resistance, deviation ±10% Immediate replacement

▶ Chain maintenance life and death line

  • 1:1 mix of grease + lithium greaseQuarterly refilling of chain link seams (pure grease melts in summer to attract grey)
  • Surface resistance > 10^9 Ω. Rub the wheel with alcohol cotton! If it doesn't work, change the conductive rubber wheel.

▶ Environmental control anti-commonsense operation

  • Humidifier in air conditioning vent! Humidify before heating to avoid humidity from 65% → 24%
  • Ion fan ≤ 50cm from the work plate, static voltage exceeds ± 50 V. Use a lighter to burn tungsten needles to remove carbon deposits.

V. Sudden electrostatic failure? 3-minute self-help flowchart

Don't turn off the power to the flowline alarm! Troubleshoot in that order:

make a copy of
Static alarm → Check grounding resistance (>10Ω? Polishing contact points)
↓ Normal
Check roller resistance (>10^9Ω? Alcohol wipe/change wheel)
↓ Normal
Measure ambient humidity (<40%? Humidifier replenishment + check air conditioning)  

With life-saving data.For every 10%RH increase in humidity, the electrostatic voltage decreases by 50%.
