Chargers yog raug rau ntau hom kev soj ntsuam, xws li tsos, qauv, daim ntawv lo, kev ua haujlwm tseem ceeb, kev nyab xeeb, kev hloov hluav taws xob, hluav taws xob sib raug zoo, thiab lwm yam.
Charger tsos, qauv thiab daim ntawv lo tshuaj xyuas
1.1.Cov tsos mob thiab cov qauv: qhov saum npoo ntawm cov khoom yuav tsum tsis txhob muaj qhov pom tseeb dents, khawb, tawg, deformations los yog muaj kuab paug.Cov txheej yuav tsum tsis tu ncua thiab tsis muaj npuas, fissures, shedding los yog abrasion.Cov khoom siv hlau yuav tsum tsis txhob xeb thiab yuav tsum tsis txhob muaj lwm yam kev puas tsuaj.Cov khoom sib txawv yuav tsum tau fastened yam tsis muaj looseness.Cov keyboards, nyees khawm thiab lwm qhov chaw tswj yuav tsum hloov tau thiab txhim khu kev qha.
1.2.Kev sau npe
Cov ntawv sau hauv qab no yuav tsum tshwm sim ntawm qhov chaw ntawm cov khoom:
Khoom npe thiab qauv;cov chaw tsim khoom lub npe thiab cov cim lag luam;rated input voltage, input tam sim no thiab siab tshaj plaws tso zis zog ntawm lub xov tooj cua transmitter;rated tso zis voltage thiab hluav taws xob tam sim no ntawm lub receiver.
Charger marking thiab ntim
Kos npe: cov cim ntawm cov khoom yuav tsum tsawg kawg suav nrog cov khoom npe thiab qauv, chaw tsim khoom lub npe, chaw nyob thiab cov cim lag luam thiab cov khoom pov thawj.Cov ntaub ntawv yuav tsum yog luv, meej, raug thiab ruaj khov.
Sab nraum lub thawv ntim khoom yuav tsum tau cim nrog cov chaw tsim khoom lub npe thiab cov qauv khoom.Nws kuj yuav tsum tau muab tshuaj tsuag los yog txuas nrog cov ntawv qhia kev thauj mus los xws li "Fragile" lossis "Keep deb ntawm dej".
Ntim: lub thawv ntim khoom yuav tsum ua raws li cov ntaub ntawv pov thawj, plua plav pov thawj thiab tiv thaiv kev co.Lub thawv ntim khoom yuav tsum muaj cov ntawv ntim khoom, daim ntawv pov thawj tshuaj xyuas, cov ntaub ntawv tsim nyog thiab cov ntaub ntawv ntsig txog.
Kev tshuaj xyuas thiab kev sim
1. Kev ntsuas hluav taws xob siab: txhawm rau xyuas seb cov khoom siv puas ua raws li cov kev txwv no: 3000 V / 5 mA / 2 sec.
2. Routine charging performance test: tag nrho cov khoom kuaj tau raug tshuaj xyuas los ntawm cov qauv ntsuas kev txawj ntse los xyuas qhov kev ua tau zoo thiab qhov chaw nres nkoj.
3. Kev ntsuam xyuas kev them nqi ceev: kev them nqi ceev yog kuaj nrog lub xov tooj smartphone.
4. Qhov ntsuas qhov ntsuas lub teeb: txhawm rau xyuas seb lub teeb qhia lub teeb puas tig thaum siv hluav taws xob.
5. Output voltage check: xyuas qhov yooj yim paug muaj nuj nqi thiab sau cov ntau yam ntawm cov zis (rated load thiab unload).
6. Kev ntsuas kev tiv thaiv overcurrent: txhawm rau xyuas seb qhov kev tiv thaiv hluav taws xob puas muaj txiaj ntsig hauv cov xwm txheej overcurrent thiab xyuas seb cov khoom puas yuav kaw thiab rov qab mus rau qhov qub tom qab them nyiaj.
7. Kev ntsuas kev tiv thaiv luv luv: txhawm rau xyuas seb qhov kev tiv thaiv puas muaj txiaj ntsig ntawm kev tiv thaiv luv luv.
8. Output voltage adapter nyob rau hauv tsis muaj-load tej yam kev mob: 9 V.
9. Daim kab xev ntsuas los ntsuas txheej adhesion: kev siv 3M #600 daim kab xev (los yog sib npaug) los kuaj tag nrho cov tshuaj txau, kub stamping, UV txheej thiab luam ntawv adhesion.Nyob rau hauv txhua rooj plaub, lub faulty cheeb tsam yuav tsum tsis txhob ntau tshaj 10%.
10. Barcode scanning test: txhawm rau txheeb xyuas qhov barcode tuaj yeem luam tawm thiab cov txiaj ntsig scan yog qhov tseeb.
