Kodi Kiyibodi ya Silicone Imagwira Ntchito Bwanji?

 

 

Choyamba, tiyeni tiwone kuti Silicone Keypad ndi chiyani?

SMa keypad a rabara a ilicone (omwe amadziwikanso kuti Elastomeric Keypad) amagwiritsidwa ntchito kwambiri pazinthu zamagetsi zamagetsi zomwe zimagwiritsidwa ntchito ndi ogula komanso mafakitale monga njira yotsika mtengo komanso yodalirika yosinthira.

Mu mawonekedwe ake osavuta, keypad ya silicone kwenikweni ndi "chigoba" chomwe chimayikidwa pamwamba pa ma switch angapo kuti chipereke malo omasuka komanso ogwira mtima kwa ogwiritsa ntchito. Pali mitundu ingapo ya keypad ya silicon. JWT Rubber imatha kupanga keypad yokhala ndi zinthu zapamwamba kwambiri kuposa zomwe zalembedwa pansipa. Koma ndikofunikira kuti wopanga aliyense amvetsetse njira yonse yomwe keypad ya silicon imasinthira mawu a ogwiritsa ntchito kukhala zizindikiro zomwe zimagwiritsa ntchito zamagetsi ndi makina.

 

Kupanga Makiyi a Silicone

Ma keypad a silicone amapangidwa ndi njira yotchedwa compression molding. Njirayi imagwiritsa ntchito kuphatikiza kwa kupanikizika ndi kutentha kuti ipange malo opindika (koma olimba) ozungulira kulumikizana kwamagetsi pakati. Ma keypad a silicone amapangidwa kuti apange yankho lofanana logwira pamwamba ponse. Amapangidwa kuti asakhale ndi mbali zamagetsi kotero kusokoneza kwa zinthuzo sikofunikira pakugwiritsa ntchito chipangizocho.

Chinthu chimodzi chofunika kuganizira pa ma keypad a silicon ndi kuthekera kopanga keypad yonse kukhala chidutswa chimodzi cha silicone, m'malo mopanga makiyi osiyana. Pa chipangizo monga remote control, izi zimathandiza kuti kupanga kukhale kosavuta (ndi kuchepetsa ndalama) chifukwa keypad ikhoza kuyikidwa ngati chidutswa chimodzi pansi pa chipangizo chogwirira pulasitiki. Izi zimawonjezeranso kukana kwa chipangizo ku madzi ndi kuwonongeka kwa chilengedwe. Mwachitsanzo, ngati mutaya madzi pa keypad ya silicon yomwe imapangidwa ndi silicone imodzi yolimba, madziwo amatha kuchotsedwa popanda kulowa mu chipangizocho ndikuwononga zigawo zamkati.

 

Ntchito Zamkati za Silicone Keypad

Pansi pa kiyi iliyonse pa keypad ya silicone pali mndandanda wosavuta wa kulumikizana kwamagetsi komwe kumathandiza kupereka ma pompo amagetsi pamene makiyi atsekedwa.

Mukakanikiza kiyi pa keypad, imatseka gawo la ukonde wa silicone. Mukakanikiza mokwanira kuti piritsi la kaboni/golide pa kiyi likhudze kukhudzana kwa PCB pansi pa kiyiyo kuti mumalize kuzungulira, zotsatira zake zimakhala zatha. Ma switch contacts awa ndi osavuta kwambiri, zomwe zikutanthauza kuti ndi otsika mtengo komanso olimba KWAMBIRI. Mosiyana ndi zida zina zambiri zolowera (poyang'ana inu, makiyibodi amakina), moyo wogwira ntchito wa keypad ya silicone ndi wopanda malire.

 

Kusintha Ma Keypad a Silicone

Kapangidwe ka silicone kamalola kusintha kwakukulu kwa keypad yokha. Kuchuluka kwa kupanikizika komwe kumafunika pokanikiza kiyi kungasinthidwe mwa kusintha "kuuma" kwa silicone. Izi zitha kutanthauza kufunikira mphamvu yayikulu yogwira kuti ichepetse switch (ngakhale kapangidwe ka webbing kakadali kothandiza kwambiri pa mphamvu yoyendetsera). Kapangidwe ka kiyi kamathandizanso pakumva kwake konse kogwira. Mbali iyi yosinthira imatchedwa "snap ratio", ndipo ndi mgwirizano pakati pa kuthekera kopangitsa makiyi kumva odziyimira pawokha/ogwira, komanso chikhumbo cha opanga kupanga keypad yomwe idzakhala ndi moyo wautali. Ndi snap ration yokwanira, makiyi adzamva ngati "akudina", zomwe zimakhutiritsa wogwiritsa ntchito, ndikuwapatsa ndemanga kuti zomwe apereka zidamveka ndi chipangizocho.
