npib xaub xaub: if you're buying coin pusher machines from China, don't guess-inspect. Cov lus qhia ua haujlwm no {{2} Cov Lus Qhia Kev Ntsuas, Hearing Confitection, Firmware Kev Ntsuas, thiab hlawv {{4 4}} hauv kev siv tau. Thaum kawg koj tuaj yeem rub tawm ib qho kev npaj txhij - {{{{-}}}}}} Kev tshuaj ntsuam cov ntawv txheeb xyuas thaum lub sijhawm kuaj xyuas.
Vim li cas thiaj khiav lub Hoobkas kuaj xyuas? (Dab tsi yog lub hom phiaj?)
Lub Hoobkas tshuaj xyuas thiab kuaj ntsuas piv txwv tiv thaiv cov nqi them rau cov neeg mob siab, kev tsis txaus siab, thiab cov neeg tsis txaus siab. Rau npib viber kev sib cav, cov tsis muaj zog me (lub cev muaj zog tsis muaj zog, lossis kev tiv thaiv tsis zoo) txhais tau tias thiab poob qis hauv koj lub tsev. Siv qhov noLub Hoobkas Tshawb Hlaws Coin Pushercov ntawv txheeb kom tiv thaiv cov npoo thiab lub koob npe nrov.
1. Ntim & Crate Soj ntsuam - Yuav ua li cas thiaj kuaj (yuav ua li cas nws)
Txheeb xyuas sab nraud muaj zog, kaum tiv thaiv, noo noo kev thaiv, thiab cov cim xa khoom kom raug.
Qhib tus qauv CRATE: Tshawb xyuas sab hauv Cushioning (ua npuas ncauj / ply), sepurators, thiab immobilization. Txom Nyem Cov Khaub Ncaws Ua rau muaj kev puas tsuaj rau kev puas tsuaj - daim ntawv nrog cov duab.
2. PCB & Kev Soj Ntsuam Hluav Taws Xob -} Cov cim tseem ceeb los saib
Tshuaj xyuas cov quav pob qij txha, qhov chaw muab tso ua ke, thiab txheej txheem txheej txheem. Txias solder pob qij txha, flux residue, lossis cov khoom uas tsis muaj npe yog chij liab.
Siv tau cov hom tseem ceeb rau cov khoom tseem ceeb (kev xaiv cov tswj hwm (Mosfets) thiab thov IPC Daim Ntawv Ntsuam Xyuas IPC.
3. Tsav & Iav lub neej ntsuas - Vim li cas nws hotters
Khiav lub neej lub neej mus ncig ntawm cov qauv ntsuas (pom zoo 1,000-10,000 lub voj voog mus raws li kev txheeb xyuas ntawm SPEC) thiab ntsuas tam sim no kos. Kev kwv yees ntau dhau los los yog suab kwv yees ua tsis tau thaum ntxov.
Nug txog rau cov ntaub ntawv MTBF thiab cov teeb meem sim cov qauv. "Lub cev muaj zog" ua tsis tiav yog qhov ua rau ntawm kev sib tham hauv nruab nrab.
4. Hopper, Npib Path & Siv Tau Cov Ntawv Checkator
Kuaj nyiaj npib ntws nrog phiaj denominations thiab tokens; Nco ntsoov cov kev ntsuas nkag mus rau npe thiab Hopper mechanism tsis muaj jam.
Siv tau tus nqi sam thiaj los yog tus siv tau yog suav nrog; Txheeb xyuas calibration thiab dag kev xyeej tus nqi.
5. Firmware, Version Control & Kev Teeb Meem
Xyuas kom meej firmware version phim spec thiab yog daim ntawv lo. Thov cov txheej txheem rau kev nyab xeeb firmware hloov kho thiab nug seb bootloader qhov ntsuas tau thov.
Paub meej tias cov chaw them rau cov nyiaj them nuj nqis thiab daim pib muab kev nkag tau tsuas yog siv cov kev pabcuam txheeb xyuas qhov tseeb.
6. Cov ntaub ntawv, spare - ntu & sau npe
Yuav tsum muaj ib qho khoom seem {{{}}} daim ntawv teev (rubbers, motors, fuses, fuses, qij) thiab sau npe rau PCB connectors. Ib qho muaj feem cuam spare - khoom siv txo MTTR.
Tau txais cov neeg siv phau ntawv qhia, daim duab hlau hluav taws xob, thiab QC cov ntawv qhia ua lus Askiv.
7. Hlawv -} hauv & Lub Rooj Vis Fobal)
Ua ib qho 8-24 teev hlawv - hauv kev khiav kom piav qhia kev sib cais. Thaum lub sij hawm hlawv - hauv, saib hloov / sensor ua tsis tiav, lub suab / led yuam kev, thiab tsis khov firmware tus cwj pwm.
Teev cov qhabnias thiab tsuas yog lees txais cov kab ke uas dhau ntawm lub chaw nres nkoj.
Cov Lus Qhia Ua Tau Zoo
- Kev txiav txim ua piv txwv ua ntej loj:1-2 kev coj mus kuaj, khiav tag nrho kev tshuaj xyuas thiab hlawv - hauv.
- Hais lusinging & MOQ:Cia siab tias tus nqi lov ntawm 10-50 units; Nug rau FOB thiab CIF cov lus thiab cov ntsiab lus hauv Freight & Dest.
- Thib peb -} THOOB ZC:Siv kev tshuaj xyuas kev ywj pheej (piv txwv li, SGS, Bureau Veritas) rau ua ntej- Cov tshev xa tawm.
- SLA & spare xeem:Txhais tau RMA cov ntsiab lus, cov txhuas lub sij hawm rau cov khoom muag tseem ceeb (Motors, PCBs) thiab hloov tus nqi hauv daim ntawv cog lus.
Tuam Tshoj Sourcing Qhov Tshwj Xeeb
Siv cov lus hom lus hauv zos thiab hais kom paub cov ntaub ntawv Askiv. Rau pcb seem, kuaj xyuas keeb kwm thiab RoHS / mus txog kev ua raws li EU. Rau lub neej muaj zog, thov lub cav nrog ntsuas ntsuas tam sim no thiab qhov kub. Ntim yuav tsum tau ua kom muaj raws li cov qauv crate los tiv thaiv cov khoom thaum caij hiav txwv ntev.
