Nyob rau hauv lub nthwv dej ntawm manufacturing transformation thiab upgrading, lub folding tshuab raws li cov khoom tseem ceeb ntawm cov ntawv hlau ua, nws automation theem ncaj qha cuam tshuam rau ntau lawm efficiency thiab cov khoom zoo. Cov cuab yeej siv niaj hnub tso siab rau cov cuab yeej siv tshuab lossis PLC tswj tau yooj yim, uas muaj cov teeb meem ntawm qhov tsis txaus ntseeg qhov tseeb, cov lus teb qeeb qeeb thiab nyuaj debugging. Los ntawm kev sib koom ua ke siab -kev ua tau zoo PLCs thiab ntau-axis servo tswj tshuab, kev tswj xyuas meej ntawm cov cuab yeej kev txav chaw, kev hloov pauv hloov pauv ntawm cov txheej txheem tsis thiab tiag- lub sijhawm sau cov ntaub ntawv tsim khoom tuaj yeem paub, tso lub hauv paus rau kev tsim khoom ntse.
I. System Architecture Design: Txheej Txheej Tswjhwm Kho vajtse-Software Synergy
1.1 Kev sib koom ua ke ntawm peb -tier architecture
Peb -txheej txheej txheej txheej ntawm ntug xam ntawm + PLC + servo tsav tsheb tau txais yuav, thiab kev faib ua haujlwm ntawm txhua txheej yog qhov tseeb:
Ntug txheej: Kev xa tawm ntawm lub PC muaj kev lag luam lossis lub rooj vag ntse los khiav Python / C + - tau tsim cov txheej txheem ua ntej los lim cov ntaub ntawv sensor, tshem tawm cov yam ntxwv, thiab tshawb xyuas qhov tsis txaus ntseeg. Piv txwv li, ib qho kev txav nruab nrab lim algorithm tuaj yeem siv los tshem tawm cov suab nrov cuam tshuam los ntawm qhov ntsuas kub, lossis qhov pib raws li txoj hauv kev tuaj yeem txiav txim siab seb cov roj siab tshaj qhov kev nyab xeeb.
Cov txheej txheem tswj: PLC ua raws li tus neeg siv khoom tseem ceeb, ua haujlwm tswj kev tswj xyuas thiab kev npaj ua haujlwm. Siemens S7-1200, piv txwv li, muaj lub zog tswj module uas tswj rau servo axes ib txhij thiab txhawb PROFINET tsheb npav kev sib txuas lus rau microsecond-theem synchronous tswj.
Txheej Txheej: Tus neeg tsav tsheb servo tau txais PLC hais kom ua thiab tsav lub cev muaj zog kom ua tiav qhov tseeb txav. Piv txwv li, ib yam khoom lag luam servo system nrog 23-ntsis encoder daws teeb meem, ua ke nrog feedforward them nyiaj algorithms, tuaj yeem txwv qhov chaw tsis raug rau ± 0.01 mmWave.
1.2 Cov cim tseem ceeb rau kev xaiv kho vajtse
PLC kev ua tau zoo: Txhawb siab -kev suav ceev (Ntau dua lossis sib npaug ntawm 200kHz), cov zis tawm suab (Ntau dua lossis sib npaug rau 1MHz), thiab ntab- taw tes lej lej kom tau raws li qhov xav tau ntawm kev tswj cov lus tsa suab.
Servo System: Xaiv cov tsav tsheb uas txhawb nqa tag nrho kaw - voj tswj nrog lub siab - kev daws teeb meem encoder (Ntau dua lossis sib npaug rau 17 khoom) txhawm rau xyuas kom them nyiaj rau cov khoom siv tsis raug.
Kev sib txuas lus Interface: Ua ntej tshaj plaws -lub sijhawm Ethernet raws tu qauv xws li PROFINET thiab EtherCAT yog qhov tseem ceeb rau ntau-axis synchronization tswj thiab qis latency cov ntaub ntawv xa mus.
ii. Servo System Integration: los ntawm cabling mus rau Parameter Optimization
