Redu­cing Risk With Visi­on-Gui­ded Laser Wel­ding

InvotecMachine Vision Systems, Micro Laser Processing, News, Precision Joining

Visi­on-gui­ded laser wel­ding is a tech­ni­que that com­bi­nes auto­ma­ted inspec­tion with tra­di­tio­nal laser wel­ding to increa­se weld qua­li­ty, impro­ve con­sis­ten­cy, and redu­ce scrap. Visi­on gui­d­ance is used in situa­ti­ons whe­re the com­bi­na­ti­on of tole­ran­ce stack-ups, beam dia­me­ter, and fea­ture size would cau­se incon­sis­tent welds. This typi­cal­ly occurs in manu­fac­tu­ring envi­ron­ments for medi­cal devices, auto­mo­ti­ve sen­sors, and other intri­ca­te pro­duc­ts that requi­re flaw­less con­sis­ten­cy despi­te tight tole­ran­ces, repe­ti­ti­ve pro­duc­tions, and com­pli­ca­ted assem­bly pro­ces­ses. Visi­on-gui­ded laser wel­ding works best in app­li­ca­ti­ons whe­re … Read More

Over­view Trim­med injec­tion mol­d­ed seals from a sprue using a laser cut­ting method that pro­vi­ded tight tole­ran­ces and did not pull, stretch or tear the mate­ri­al befo­re cut­ting each gate free with no burrs. PRO­BLEMS WE SOL­VE This medi­cal device manu­fac­tu­rer had a seal pro­duct that nee­ded to be trim­med from its mold spru­es. The­se seals did not hold their shape, were extre­me­ly pli­able and requi­red tight tole­ran­ce cuts to make an accep­ta­ble assem­bly. The trim­ming pro­cess could not pull, … Read More

Over­view Desi­gned and instal­led a new, ful­ly auto­ma­tic assem­bly and test sys­tem to assem­ble mul­ti­ple models of sprag style, auto­mo­ti­ve clutch assem­blies. A sin­gle machi­ne chas­sis was desi­red with a pair of syn­chro­nous trans­fer sys­tems cou­pled by an accu­mu­la­ting con­veyor. Model chan­ge-over requi­re­ments inclu­ded both auto­ma­tic and manu­al ope­ra­ti­ons with too­ling and posi­ti­on feed­back at all set points to veri­fy cor­rect model set­ups. PRO­BLEMS WE SOL­VE Our custo­mer nee­ded a part­ner capa­ble to design, build and install a lar­ge ful­ly … Read More

Over­view Design and Build a sys­tem to auto­ma­ti­cal­ly inspect and cor­rect spe­ci­fied dimen­sio­nal cri­te­ria on a pre­ci­se metal com­po­nent used in a medi­cal device. Auto­ma­ti­cal­ly bend to form and modi­fy the com­po­nent until it is veri­fied to be in com­pli­an­ce with the dimen­sio­nal spe­ci­fi­ca­ti­ons. Pro­blems We Sol­ve  Our custo­mer was in need of a method to dyna­mi­cal­ly inspect and cor­rect spe­ci­fied dimen­sio­nal cri­te­ria on a pre­ci­se metal com­po­nent used in a medi­cal device. Ide­al­ly this pro­cess would be able to … Read More
