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

Crea­ting Con­trast for Machi­ne Visi­on

InvotecMachine Vision Systems, News

Most manu­fac­tu­rers design their pro­duct befo­re con­si­de­ring their equip­ment needs. Howe­ver, ack­now­led­ging both simul­ta­ne­ous­ly can save time and money—especially when it comes to machi­ne visi­on sys­tems. That’s becau­se visi­on tech­no­lo­gy reli­es on con­trast for accu­ra­cy during inspec­tion. Kee­ping this in mind when selec­ting pro­duct com­pon­ents impro­ves per­for­mance and func­tio­n­a­li­ty. Here are some tricks for crea­ting con­trast your pro­duct design: Opti­mi­ze ligh­t­ing: design fea­tures that are uni­que or have a spe­cial pat­tern to take advan­ta­ge of ligh­t­ing and enhan­ce reco­gni­ti­on.

PRO­BLEMS WE SOL­VE Our cus­to­mers con­sist­ent­ly need a robust method for pre­cise wel­ding of small com­pon­ents. A natu­ral pro­cess can­di­da­te is LASER wel­ding. The issu­es with imple­men­ting laser wel­ding sys­tems can be nume­rous and chal­len­ging. Our cus­to­mers are often worried about safe­ty issu­es and weld inte­gri­ty.

The Chal­len­ge: Incre­a­se Pro­duc­tion While Eli­mi­na­ting Error One manu­fac­tu­rer, known for their high-qua­­li­­ty con­su­mer pro­ducts, faced fore­casts that their cur­rent pro­duc­tion capa­bi­li­ties could not hand­le. As a result, they nee­ded to deve­lop a sys­tem that could bet­ter faci­li­ta­te part chan­geo­ver and redu­ce cycle times—all while main­tai­ning the inte­gri­ty of their pro­duct. In addi­ti­on, the com­pa­ny was moving pro­duc­tion from Euro­pe to the US. To keep cos­ts low, the sys­tem had to accu­rate­ly assem­ble, inspect, and test their pro­duct with mini­mum … Read More
