xov xwm

Barcode Scanning Module tseem hu ua Barcode Scanning Module, Barcode Scanning Engine, ua lus Askiv (Barcode Scan Engine lossis Barcode Scan Module). Nws yog ib qho tseem ceeb ntawm kev txheeb xyuas cov khoom siv dav siv hauv kev txheeb xyuas tsis siv neeg. Nws yog ib qho ntawm cov khoom tseem ceeb rau kev txhim kho theem nrab ntawm barcode scanners. Nws muaj ua tiav thiab ywj siab barcode scanning thiab txiav txim siab ua haujlwm, thiab tuaj yeem sau ntau yam kev lag luam daim ntawv thov ua haujlwm raws li qhov xav tau. Nws muaj qhov me me thiab kev sib koom ua ke siab, thiab tuaj yeem nkag tau yooj yim hauv cov xov tooj ntawm tes, ntsiav tshuaj computers, tshuab luam ntawv, cov khoom siv sib dhos, cov khoom siv kho mob, thiab lwm yam khoom siv hauv txhua qhov chaw ntawm lub neej. Nyob rau hauv txoj kev loj hlob, lub barcode scanning module kev lag luam nyob rau hauv txawv teb chaws lub teb chaws yog tseem ntxov, thiab cov thev naus laus zis kuj paub tab. Cov loj kuj muaj xws li Honeywell, Motorola, Cim, thiab lwm yam.

1: Kev faib tawm Barcode scanning module tuaj yeem muab faib ua ib-dimensional code module thiab ob-dimensional code module raws li qhov zoo sib xws ntawm scanning, thiab tuaj yeem muab faib ua laser module thiab teeb liab module raws li lub teeb ci. Qhov sib txawv ntawm laser module thiab lub teeb liab module Lub hauv paus ntsiab lus ntawm laser scanning module yog tias cov khoom siv laser sab hauv tsim lub teeb pom kev ntawm lub teeb, ntaus ib daim ntawv qhia nrog cov cuab yeej siv tshuab, thiab tom qab ntawd tso siab rau lub tshuab vibration kom viav vias laser. mus rau hauv ib txoj kab laser thiab ci rau ntawm barcode, thiab tom qab ntawd txiav txim siab los ntawm AD. Cov teeb liab.

2: Liab lub teeb scanning modules feem ntau siv LED teeb-emitting diode lub teeb qhov chaw, cia siab rau CCD photosensitive ntsiab, thiab ces hloov lawv los ntawm photoelectric signals. Feem ntau ntawm cov laser scanning modules cia siab rau dispensing kua nplaum los kho cov cuab yeej siv tshuab, yog li nws feem ntau yooj yim puas thaum nws viav vias, thiab lub pendulum daim poob, yog li peb feem ntau pom tau tias lub teeb pom kev los ntawm qee cov phom laser dhau los ua qhov taw tes. tom qab poob. , ua rau muaj kev ua haujlwm siab ncaj ncees. Tsis muaj cov qauv siv tshuab hauv nruab nrab ntawm lub teeb liab scanning module, yog li qhov kev poob qis tsis zoo rau lub laser, yog li kev ruaj ntseg zoo dua, thiab kho tus nqi ntawm lub teeb liab scanning module yog qis dua li ntawm laser scanning. module.

3: Los ntawm lub cev lub hauv paus ntsiab lus ntawm laser thiab lub teeb liab: Laser hais txog lub teeb nrog lub zog txhawb zog hluav taws xob thiab zoo parallelism, thiab tam sim no feem ntau ntawm lub teeb liab yog tawm los ntawm LEDs. Lub teeb liab tsis yog hom infrared peb hais. Lub infrared txhais los ntawm physics yog lub spontaneous tawg ntawm cov khoom nrog kub. electromagnetic tsis, invisible. Infrared suav nrog txhua lub teeb nrog wavelengths ntau dua li lub teeb liab, thaum laser hais txog lub teeb nrog qee qhov wavelength. Ob leeg tsis muaj kev sib txuas tsim nyog thiab tsis koom nrog tib daim teb. Laser yog lub teeb hluav taws xob tsim los ntawm kev nthuav dav ntawm kev txhawb nqa emission. Infrared yog ib feem ntawm lub spectrum nrog qis zaus thiab loj dua wavelength uas tsis tuaj yeem pom los ntawm qhov muag liab qab. Lub wavelength yog los ntawm 0.76 mus rau 400 microns. Kev nkag mus thiab tiv thaiv kev cuam tshuam ntawm lub teeb yog qhov phem dua li ntawm laser, yog li sab nraum zoov laser zoo dua lub teeb liab nyob rau hauv lub teeb muaj zog.
