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.

Tech Tip: Test Sys­tems & Anti­ci­pa­ting Your Unknowns

InvotecNews, Test Systems

Solid test sys­tems are a cri­ti­cal com­po­nent in medi­cal device manufacturing—and for good rea­son. High inter­na­tio­nal stan­dards set by the FDA and CE regu­la­to­ry bodies help keep pati­ents and health­ca­re pro­fes­sio­nals safe, making com­pli­an­ce necessa­ry but not always easy to achie­ve. Robust test equip­ment hel­ps manu­fac­tu­rers ensu­re that devices can with­stand exter­nal for­ces not tes­ted during the assem­bly pro­cess. Designing the­se sys­tems always pres­ents the same chal­len­ge: engi­neers must learn to pre­dict what they don’t know. So how do they … Read More
