Coin Pusher Quality Checklist .: Sɛ woretɔ coin pusher mfiri a efi China a, nsusuw ho-hwɛ. Saa adwumayɛbea a mfaso wɔ so yi-audit akwankyerɛ yi de anammɔn ason a ɛho hia ma nneɛma a wɔkra no akuw: Packaging Integrity, PCB Inspection, Motor Life Testing, Hopper ne Coin-kwan checks, firmware controls, documentation ne spare parts, ne Burn-wɔ validation mu. Wɔ n’awiei no wobɛtumi atwe-akɔ-afa nhwehwɛmu spreadsheet adi dwuma de ayɛ adwuma wɔ nhwɛsoɔ nhwehwɛmu mu.
Dɛn nti na ɛsɛ sɛ woyɛ factory audit? (Dɛn ne botae no?)
Factory audit ne sample inspection siw mfaso a ɛho ka yɛ den, tiyɛ ho adansedi krataa, ne adetɔfo ho anwiinwii ano. Sɛ wopɛ sɛ wotɔ sika a, mfomso nketenkete (motor a ɛyɛ mmerɛw, PCB soldering a ɛyɛ dodgy, anaasɛ crate ahobammɔ a enye) kyerɛ ase kɔ agoru a ayera ne bere a wode gyae wo fam. Fa eyi di dwuma .Factory Audit Coin Pusher .Checklist a wɔde bɛbɔ margin ne din pa ho ban.
1. Packaging & Crate Inspection - Nea ɛsɛ sɛ wohwɛ (sɛnea wobɛyɛ) .
Hwɛ sɛ akyi adaka ahoɔden, ntwea so ahobammɔ, nsu a ɛyɛ nwini, ne nneɛma a wɔde fa po so hyɛn mu no yɛ nokware.
Bue nhwɛsode krataa: Hwɛ mu cushioning (foam/ply), separators, ne immobilization. Packing a ɛnyɛ papa no ma transit damage-Da mfonini ahorow ka ho.
2. PCB & Electronic Inspection - nsɛnkyerɛnne titiriw a ɛsɛ sɛ wohwɛ .
Hwɛ solder nkwaa, component placement, ne conformal coating. Awɔw solder nkwaa, flux residue, anaasɛ nneɛma a ɛyera no yɛ frankaa kɔkɔɔ.
Validate component brands ma afã horow a ɛho hia (voltage regulators, MOSFETs) na bisa IPC Visual Inspection amanneɛbɔ.
3. Motor & Gear Nkwa Sɔhwɛ - Nea enti a ɛho hia .
Run motor life cycles wɔ sample units so (wɔkamfo kyerɛ 1,000–10,000 cycles a egyina spec so) na susuw current draw. Mprempren anaa dede a ɛboro so kyerɛ sɛ ebetumi adi nkogu ntɛm.
Bisa manufacturer MTBF data ne sample test logs. "Motor Life" huammɔdi yɛ ade titiriw a ɛde field downtime ba.
4. Hopper, sika kwan & validator checks .
Sɔ sika a ɛsen no hwɛ denam asɔre ahorow a wɔde wɔn ani asi so ne token ahorow so; Hwɛ sɛ sensor ahorow no kyerɛw wo din pɛpɛɛpɛ na hopper mechanisms no nnyɛ jam.
validate bill acceptors anaa validators sɛ wɔde ka ho a; Hwɛ calibration ne nsisi a wɔpow no dodow.
5. firmware, version control & nhyehyɛe .
Hwɛ sɛ firmware version no ne spec hyia na wɔakyerɛw so. Bisa ɔkwan bi a wɔfa so yɛ firmware a ahobammɔ wom ho nsɛm foforo na bisa sɛ ebia wɔde bootloader locks di dwuma anaa.
Si nhyehyɛe a ɛfa sikatua ɔha biara mu nkyem ho si so dua na tekiti a wɔde ma no yɛ nea wotumi nya denam ɔsom kwan a wɔagye atom nkutoo so.
6. Nwoma, spare-Afã horow & nkyerɛwde .
hwehwɛ sɛ wode spare-Parts list (rɔba, motors, fuses, bulbs) ne nkyerɛwde a wɔde kyerɛw PCB nkitahodi ahorow. An included spare-kit tew MTTR so.
Nya dwumadie ho nkyerɛkyerɛmu, wiring diagrams, ne QC amanneɛbɔ wɔ Borɔfo kasa mu.
7. Ɔhyew-wɔ & dwumadi sɔhwɛ mu (apon a etwa to) .
Yɛ dɔnhwerew 8–24 hyew-wɔ run mu ma ɛda mfomso ahorow a ɛba bere ne bere mu adi. Bere a ɛrehyew-wɔ mu no, hwɛ sɛ switch/ sensor huammɔdi, ɔdio/led mfomso, ne firmware suban a entumi nnyina.
Log aba na gye batches a ɛtwam defined thresholds nkutoo.
Nneɛma a wɔde tɔ ade ho afotu a mfaso wɔ so .
- Kɔkra nhwɛsode ansa na woayɛ kɛse:1–2 sample units, run full inspections na hyew-in.
- Nsusuiɛ a ɛwɔ Tooling & MOQ:Hwɛ kwan sɛ ɛboɔ mu bɛpae wɔ 10–50 units; Bisa FOB vs. CIF quotes na factor wɔ freight & duty mu.
- Nea ɛto so abiɛsa-afã QC:Fa independent inspection (sɛ nhwɛso no, SGS, Bureau Veritas) di dwuma ma pre-ahyɛn mu nhwehwɛmu.
- SLA & spare parts: .Kyerɛkyerɛ RMA nsɛmfua, bere a wɔde di anim ma spares a ɛho hia (motors, PCBs) ne ɛka a wɔbɔ wɔ apam no mu.
China Sourcing Nsɛm pɔtee bi .
Fa ɛhɔnom kasa ho nsɛm di dwuma na si so dua wɔ Borɔfo nkrataa ho. Wɔ PCB afã horow ho no, hwɛ sɛ component origin ne ROHS/Reach compliance sɛ wɔtɔn ma EU a. Wɔ motor nkwa ho no, bisa sɔhwɛ logs a wɔasusuw current ne ambient temperatures. Ɛsɛ sɛ nneɛma a wɔde kyekyere nneɛma ho no du export crate gyinapɛn ahorow ho de bɔ nneɛma ho ban bere a ɛpo no retu kwan tenten no.
