Weld seam nrhiav thiab weld seam positioning yog ob txoj haujlwm sib txawv siv hauv vuam automation. Weld seam tracking thiab weld seam positioning yog ob txoj kev siv thev naus laus zis uas ua lub luag haujlwm tseem ceeb hauv cov txheej txheem vuam.
Weld seam positioning, tseem hu ua weld seam induction, yog tus txheej txheem ntawm kev kuaj xyuas txoj hauj lwm thiab kev taw qhia ntawm seam ntawm lub workpiece ua ntej txoj kev vuam pib. Qhov no feem ntau yog ua tiav los ntawm kev siv cov sensors thiab software program los coj cov phom vuam mus rau qhov tseeb ntawm txoj hlua khi. Lub hom phiaj ntawm weld seam positioning yog los xyuas kom meej tias welding raug siv rau lub vuam seam, uas yog qhov tseem ceeb rau kev ua kom lub zog thiab kev ncaj ncees ntawm vuam. Tsis tas li ntawd, weld seam positioning pab kom txo tau qhov tsis xws luag xws li notches, overfilling, thiab hlawv los ntawm.
Muaj ntau ntau txoj hauv kev los nrhiav cov vuam seams, suav nrog tactile induction, kab induction, thiab laser induction. Tactile sensing yog ib txoj hauv kev tshawb xyuas cov seams los ntawm lub cev tiv thaiv qhov chaw ntawm lub workpiece nrog ib tug hlau los yog nozzle. Txoj kev no yog qhov yooj yim thiab txhim khu kev qha, tab sis nws qeeb thiab muaj kev txwv hauv kev tshawb xyuas qhov sib txawv ntawm qhov sib txuas. Kab sensing zoo ib yam li tactile sensing, tab sis nws siv lub servo lub cev muaj zog kom ceev ceev txoj kab nce thiab nqis raws li tus neeg hlau txav raws workpiece. Txoj kev no tuaj yeem ntes pob tw welds uas nyuaj rau nrhiav tau siv cov kab zoo li qub lossis nozzle hu rau induction, tab sis yuav tsum muaj cov khoom siv tshwj xeeb thiab software. Laser induction yog ceev tshaj tactile induction thiab tuaj yeem ntes cov seams nrog lub thickness ntawm 1/16 nti. Txawm li cas los xij, muaj cov kev txwv hauv kev txheeb xyuas qhov sib txawv ntawm qhov sib txawv, vim tsis tuaj yeem pom cov pob tw welds.
Ntawm qhov tod tes, weld seam taug qab yog cov txheej txheem ntawm kev taug qab txoj hauv kev ntawm vuam seam thaum lub vuam txheej txheem. Qhov no yog ua tiav los ntawm kev siv cov sensors thiab software cov kev pab cuam los coj cov phom welding nyob rau hauv lub sij hawm ntawm lub weld seam. Lub hom phiaj ntawm weld seam taug qab yog los xyuas kom meej tias welding raug siv rau qhov vuam seam, txawm tias txoj hauj lwm lossis cov duab ntawm cov seam hloov. Qhov no yog qhov tseem ceeb rau kev ua kom muaj zog vuam thiab sib xws, txawm tias lub workpiece raug cuam tshuam los ntawm thermal expansion lossis lwm yam uas ua rau deformation.
Muaj ntau txoj hauv kev rau kev taug qab seam, suav nrog arc nrhiav, laser nrhiav, thiab pom kev pom. Arc taug qab yuav tsum ntsuas arc yam ntxwv thaum lub vuam txheej txheem los txiav txim qhov txawv ntawm txoj kev qhia los ntawm tus neeg hlau thiab txoj kev vuam tiag tiag. Txoj kev no yog tsim rau qhov chaw nrog ntev los yog nkhaus welds, uas yuav txawv ntawm ib feem mus rau lwm qhov. Laser nrhiav siv laser sensors ua raws li lub vuam seam thaum lub sij hawm vuam txheej txheem, muab cov lus qhia ntawm lub sij hawm rau tus neeg hlau kom paub tseeb tias cov ntaub ntawv raug vuam rau vuam seam. Kev pom kev taug qab siv lub koob yees duab los ntes cov duab weld seam thaum lub sij hawm vuam txheej txheem, uas tom qab ntawd soj ntsuam los ntawm software los coj tus neeg hlau mus rau hauv lub vuam seam. Txoj kev no yog tsim rau cov khoom siv nrog cov duab geometric complex lossis deformed workpieces.
Hauv cov ntsiab lus, weld seam positioning thiab taug qab yog cov haujlwm tseem ceeb hauv vuam automation, tab sis lawv muaj kev siv sib txawv thiab tso siab rau cov thev naus laus zis sib txawv. Weld seam positioning yog siv los txheeb xyuas txoj hauj lwm thiab kev taw qhia ntawm lub vuam seam ua ntej cov txheej txheem vuam pib, thaum weld seam taug qab yog siv los taug qab txoj hauv kev ntawm vuam seam thaum lub sij hawm vuam txheej txheem. Ob txoj haujlwm no yog qhov tseem ceeb rau kev ua kom zoo dua qub thiab zoo ntawm cov txheej txheem vuam, thiab tuaj yeem pab txo qis qhov tsis xws luag, txhim kho lub zog thiab kev ncaj ncees ntawm welds.
