Mbiri

Mtundu watsopano wa UL 1642 unatulutsidwa.Njira ina yoyesera zolemetsa imawonjezedwa pama cell athumba.Zofunikira zenizeni ndi izi: Kwa cell cell yokhala ndi mphamvu yopitilira 300 mAh, ngati mayeso olemera sanadutse, atha kuyesedwa ndi Gawo 14A mozungulira ndodo yoyeserera.

Selo la thumba lilibe vuto lolimba, lomwe nthawi zambiri limabweretsa kuphulika kwa ma cell, kuthyoka kwa ma tap, zinyalala zomwe zimawulukira kunja ndi kuwonongeka kwina kwakukulu komwe kumachitika chifukwa cholephera kuyeserera kwakukulu, ndipo zimapangitsa kuti zikhale zosatheka kuzindikira dera lalifupi lamkati lomwe limayambitsidwa ndi vuto la kapangidwe kake kapena kuwonongeka kwa dongosolo. .Ndi kuyesa kozungulira ndodo, zolakwika zomwe zingatheke mu cell zitha kudziwika popanda kuwononga ma cell.Kuwunikiridwako kudapangidwa ndi izi poganizira.

Mayendedwe oyesera

• Zitsanzozo zimalipidwa mokwanira monga momwe wopanga amalimbikitsira
• Ikani chitsanzo pamalo ophwanyika.Ikani ndodo yozungulira yachitsulo yokhala ndi mainchesi 25±1 mm pamwamba pa chitsanzo.Mphepete mwa ndodo iyenera kugwirizanitsidwa ndi pamwamba pa nsonga ya selo, ndi chigawo chokhazikika cha perpendicular to tabu (FIG. 1).Utali wa ndodoyo uyenera kukhala wosachepera 5mm m'lifupi kuposa m'mphepete mwachitsanzo choyesera.Kwa ma cell okhala ndi ma tabo abwino ndi oyipa mbali zotsutsana, mbali iliyonse ya tabu iyenera kuyesedwa.Mbali iliyonse ya tabu iyenera kuyesedwa pazitsanzo zosiyanasiyana.
• Kuyeza makulidwe (tolerance±0.1mm) yama cell iyenera kuchitidwa isanayambe kuyezetsa molingana ndi Zowonjezera A za IEC 61960-3 (maselo achiwiri ndi mabatire okhala ndi alkaline kapena ma electrolyte ena osakhala acidic - Ma cell achiwiri a lithiamu ndi mabatire - Gawo 3: Prismatic ndi cylindrical lithiamu sekondale ma cell ndi mabatire)
• Ndiye Finyani kuthamanga ntchito pa ndodo yozungulira ndi kusamuka mu njira ofukula amalembedwa (FIG. 2).Kuthamanga kwa mbale yosindikizira sikuyenera kupitirira 0.1mm / s.Pamene mapindikidwe a cell afika 13±1% ya makulidwe a cell, kapena kupanikizika kumafika pamphamvu yomwe ikuwonetsedwa mu Gulu 1 (ma cell makulidwe osiyanasiyana amafanana ndi mphamvu zosiyanasiyana), siyani kusuntha kwa mbale ndikuigwira kwa 30s.Mayeso amatha.
• Palibe moto kapena kuphulika kwa zitsanzo.

Kusanthula moyesera

• Kusankhidwa kwa malo otulutsira: malo a pole tab nthawi zambiri amakhala malo ofooka a thumba, ndipo malo a tabu amakhala ndi kupsinjika kwakukulu akamafinyidwa.Zifukwa zake ndi:

a) Kugawanika kwa makulidwe osagwirizana (kuchuluka kosagwirizana pakati pa tabu yamtengo ndi chinthu chozungulira chomwe chimagwira kumabweretsa kugawanika kosagwirizana)

b) Zizindikiro zowotcherera pagawo la tabu (kugawa kupsinjika pamalo owotcherera komanso malo osawotcherera)

• Kusankhidwa kwa ndodo yozungulira: Kuzungulira kwa ndodo yozungulira ndi 25mm.Mtengowu umasankhidwa kuti ukwaniritse gawo lonse la tabu yamtengo mu cell (makamaka malo omwe amaphimba cholumikizira cha pole tabu).
• 13±1% mapindikidwe: Pakadali pano, makulidwe a cell thinnest pamsika ndi 2mm.Chifukwa cha chikoka cha batire mpanda kapena ma CD ndondomeko, osachepera 8% mtundu variable chofunika psinjika ndi mzati tabu solder olowa, koma mwachindunji kutsogolera electrode akulimbana ngati kusintha mtundu ndi lalikulu kwambiri.Mtengo wa 13±1% idasankhidwa pakukonzanso uku, kutanthauza kusinthika kwapakati 15% pamayeso a extrusion mu IEC 62660-3.
• Kusankha kwachitsanzo: Dziwani kuti kuyesaku ndi kwa ma cell a thumba okha omwe mphamvu yake ndi yayikulu kuposa 300mAh ndipo sanagundidwe ndi zinthu zolemera.5 zitsanzo zofunika.Ma cell a Cylindrical kapena prismatic ndi ma cell thumba omwe amagundidwa ndi zinthu zolemetsa't ndizoyenera kuganiziridwa pa mayesowa.

Chidule

Kuyesa kwatsopano kwa ndodo yozungulira ndikosiyana ndi kuyesa koyambirira kwa UL 1642. Mayeso oyambirira a extrusion ndi kugwiritsa ntchito flat extrusion, ndikugwiritsa ntchito mphamvu ya 13kN nthawi zonse popanda kugwira nthawi.Imagwira pamitundu yonse ya ma cell.Mayesowa amawunika mphamvu zamakina a selo lonse (kuphatikiza mlandu) komanso kuthekera kwake kolimbana ndi kupsinjika kwamakina;pamene chozungulira ndodo extrusion amangoyesa gawo la selo, malo ang'onoang'ono a indenter adzapanga kupsyinjika mkati mokhazikika, kosavuta kutsogolera kufupi kwapakati mkati.Makamaka, malo a extrusion amasankhidwa m'dera lofooka la kuwotcherera tabu, zomwe zingathe kufufuza bwino ntchito ya chitetezo cha selo.

Pakalipano, njira yozungulira iyi imagwiritsidwanso ntchito poyesa extrusion ya cell thumba mu GB 31241. MCM ili ndi chidziwitso chochuluka choyesa pa ntchitoyi.
