coin pusher mndandanda wamtundu: ngati mukugula makina opopera ndalama ku China, musaganize-onani. Fakitale iyi-yowongolera owerengera ili ndi masitepe asanu ndi awiri ofunikira a magulu ogula zinthu: kulondola kwapackaging, kuyang'anira PCB, kuyesa moyo wagalimoto, ma hopper ndi coin-kufufuza njira, zowongolera za firmware, zolemba ndi zotsalira, ndi kuwotcha{4}zotsimikizira. Pamapeto pake mukhoza dawunilodi-yokonzeka-kugwiritsa ntchito inspection spreadsheet kuti muyigwiritse ntchito pofufuza zitsanzo.
N'chifukwa chiyani mumayang'anira ntchito ya fakitale? (Cholinga ndi chiyani?)
Kuwunika kwa fakitale ndikuwunika kwachitsanzo kumateteza kubweza kwamtengo wapatali, kupwetekedwa mutu kwa chitsimikizo, ndi madandaulo a makasitomala. Pakugula ndalama zachitsulo, zolakwika zing'onozing'ono (motor yofooka, kutenthetsa kwa PCB, kapena kutetezedwa kwa crate) kumasulira masewero otayika ndi nthawi yopuma pansi panu. Gwiritsani ntchito izifakitale audit coin pushermndandanda kuti muteteze malire ndi mbiri.
1. Kuyika & kuyendera ma crate - zoyenera kuyang'ana (Mmene mungachitire)
Tsimikizirani mphamvu zamakrete akunja, zoteteza pamakona, zotchingira chinyezi, ndi zizindikiro zolondola zotumizira.
Tsegulani kabokosi kachitsanzo: yang'anani zotsekera mkati (thovu/ply), zolekanitsa, ndi kusasunthika. Kusanyamula bwino kumabweretsa kuwonongeka-zolemba zomwe zili ndi zithunzi.
2. PCB & kuyendera pakompyuta - ma sigino ofunikira kuti muwone
Yang'anani zolumikizira zogulitsira, kuyika kwazinthu, ndi zokutira zofananira. Kuzizira kwa solder, zotsalira za flux, kapena zida zomwe zikusowa ndi mbendera zofiira.
Tsimikizirani mitundu yazigawo zofunika kwambiri (zowongolera magetsi, ma MOSFET) ndikufunsani lipoti la IPC.
3. Kuyesa moyo wa injini ndi zida - chifukwa chake kuli kofunikira
Yendetsani maulendo agalimoto pazitsanzo za mayunitsi (omwe akulimbikitsidwa kuti azizungulira 1,000–10,000 kutengera momwe) ndikuyezera mawonekedwe apano. Kuchuluka kwamakono kapena phokoso kumaneneratu kulephera koyambirira.
Funsani deta ya wopanga MTBF ndi zolemba zoyeserera. Kulephera kwa "Motor Moyo" ndizomwe zimayambitsa kutsika kwamunda.
4. Hopper, njira ya ndalama & macheke ovomerezeka
Yesani kuyenda kwa ndalama ndi zipembedzo ndi ma tokeni; onetsetsani kuti masensa amalembetsa molondola ndipo makina opangira ma hopper sakusokoneza.
Tsimikizirani olandila mabilu kapena otsimikizira ngati aphatikizidwa; fufuzani mawerengedwe ndi kukana kwachinyengo mitengo.
5. Firmware, kuwongolera mtundu & kasinthidwe
Onetsetsani kuti mtundu wa firmware ukugwirizana ndi zomwe zalembedwa. Funsani njira yosinthira zosintha za firmware ndikufunsa ngati maloko a bootloader agwiritsidwa ntchito.
Tsimikizirani zochunira zamaperesenti olipira komanso kutulutsa matikiti kumafikirika kudzera mumayendedwe ovomerezeka.
6. Zolemba, -zigawo zotsalira & zolemba
Pamafunika -mndandanda wa magawo (rabala, ma mota, fuse, mababu) ndi zilembo za zolumikizira za PCB. Zotsalira zophatikizidwa-zimachepetsa MTTR.
Pezani zolemba za ogwiritsa ntchito, zojambula zamawaya, ndi malipoti a QC mu Chingerezi.
7. Yesetsani{1}}ndi kuyesa ntchito (chipata chomaliza)
Yatsani kwa maola 8-24-pothamanga kuti muwone zolakwika zapakatikati. Mukawotcha-, yang'anani ngati kusintha kwasintha/kulephera kwa sensor, zolakwika za audio/LED, ndi machitidwe osakhazikika a firmware.
Lowetsani zotsatira ndikungovomereza magulu omwe amadutsa malire omwe afotokozedwa.
Malangizo othandiza pogula zinthu
- Onjezani zitsanzo musanachuluke:1–2 zitsanzo zamayunitsi, fufuzani zonse ndikuwotcha-mkati.
- Kambiranani zida & MOQ:kuyembekezera kutsika kwamitengo pamagulu 10-50; funsani zolemba za FOB motsutsana ndi CIF ndi zomwe zimatengera katundu ndi ntchito.
- QC yachitatu-:gwiritsani ntchito kuunika kodziyimira pawokha (monga, SGS, Bureau Veritas) pofufuza -kutumiza.
- SLA & zida zosinthira:fotokozani mawu a RMA, nthawi zotsogola zamagalimoto ovuta (ma motors, ma PCB) ndi ndalama zosinthira mu mgwirizano.
Zofunikira zaku China
Gwiritsani ntchito zilankhulo zakumaloko ndikulimbikira zolemba zachingerezi. Pamagawo a PCB, tsimikizirani kuti chigawocho chinachokera komanso kutsatira kwa RoHS/REACH ngati mukugulitsa ku EU. Kwa moyo wagalimoto, pemphani zipika zoyesa zoyezera kutentha kwapano komanso kozungulira. Kupaka kuyenera kukwaniritsa miyezo ya ma crate otumiza kunja kuti ateteze katundu paulendo wautali wapanyanja.
