Ib, Pwm tsim: zoo tswj los ntawm 3D qauv rau 2D layout
1. Parameter optimization thaum lub sij hawm 3D qauv
Cov pwm tsim rau customized ntsuas LCD yuav tsum tau coj los ntawm cov khoom yuav tsum tau ua. Piv txwv li, ib lub tsheb ntsuas LCD project yuav tsum tau lub vijtsam ua haujlwm ruaj khov hauv ib puag ncig ntawm -40℃txog 85 degree. Pab neeg tsim qauv yuav tsum tsom mus rau cov hauv qab no thaum lub sij hawm 3D qauv:
Kev sib piv ntawm thermal expansion coefficient: Xaiv cov khoom pwm nrog cov thermal expansion coefficient zoo ib yam li cov iav substrate (xws li stainless hlau SUS420J2) kom tsis txhob iav tawg los ntawm cov khoom deformation hauv qhov kub thiab txias.
Kev tsim qauv channel: Kev siv cov qauv sib xyaw ntawm "kub khiav + txias khiav", ua kom zoo dua cov dej ntws los ntawm kev simulation software los xyuas kom meej tias qhov sib xws ntawm cov khoom siv ua kua siv lead ua puv mus txog 98%.
Innovation ntawm demolding mechanism: Rau cov ntxaij vab tshaus tsis tu ncua (xws li nkhaus ntsuas vaj huam sib luag), "slanted top + slider" composite demolding mechanism yog tsim los daws cov teeb meem ntawm pwm sticking tshwm sim los ntawm lub inverted buckle qauv. Ib qho khoom siv kho mob LCD qhov project txo qis demolding quab yuam los ntawm 40% thiab nce lub neej pwm rau 500000 zaug los ntawm cov tshuaj no.
2. Txheej txheem kev koom ua ke thaum lub sij hawm ob -dimensional layout theem
Nyob rau hauv 2D layout theem, nws yog ib qho tsim nyog yuav tau xav txog qhov kev siv cov khoom siv, lub voj voog ua haujlwm, thiab kev sib dhos qhov tseeb tag nrho:
Modular tsim: Faib cov pwm rau hauv peb qhov loj: "pem hauv ntej pwm + rear pwm + swb pawg", thiab ua tiav pwm hloov pauv los ntawm cov txheej txheem sib cuam tshuam. Tom qab siv qhov kev daws teeb meem no hauv qhov project tswj kev lag luam LCD, lub sijhawm hloov pwm raug txo los ntawm 8 teev mus rau 2 teev.
Tib xim thiab tib cov txheej txheem ua pawg: Npaj cov khoom uas yuav tsum tau electroplated nyob rau hauv lub hauv paus ntsiab lus los txo qhov zaus ntawm plating tank tov hloov. Ib qho ntawm cov neeg siv khoom siv hluav taws xob LCD qhov project tau txo cov nqi hluav taws xob los ntawm 15% los ntawm qhov kev ua kom zoo dua no.
Embedded embedded thev naus laus zis: Rau cov pwm uas xav tau kev sib txuas ntawm FPC, cov qauv kev nyab xeeb dual ntawm "txoj haujlwm tus pin + lub tshuab nqus tsev nqus" yog tsim los xyuas kom meej tias qhov chaw embedded qhov tseeb yog nyob rau hauv ± 0.05mm.
