AccuFast II Tackles Seams Quickly and with Quality

May 4, 2018

Motoman provides users with add-on features to help enhance the seam finding for their automated welding line. AccuFast II offers improved sensor capabilities that provide even higher amounts of reliability. It provides more readings for a wider range of materials and angles not formerly feasible.

Yaskawa Motoman offers a vari­ety of seam find­ing tools to locate seams fast and accu­rate­ly as seen with Accu­Fast II. Parts aren’t always pre­sent­ed in a con­sis­tent loca­tion, mak­ing it dif­fi­cult to find the weld seam. Seam find­ing tools will eas­i­ly locate the upper and low­er parts and adjust as they shift. Locat­ing the upper walls or low­er parts with a seam find­ing tool helps to deter­mine the opti­mal loca­tion of the weld seam.

Accu­Fast II

Accu­Fast II is a com­pact, add-on fea­ture that is mount­ed in-line with the weld­ing torch for any Motoman weld­ing robot. It is com­pat­i­ble with Motoman’s indus­try-lead­ing MA- and VA-series thru-arm robots, as well as stan­dard 6‑axis robots. Accu­Fast II is sure to improve your weld qual­i­ty and reduce cycle times by bring­ing the fol­low­ing great features.

Improved Sen­sor

Accu­Fast II brings improved sen­sor capa­bil­i­ties that pro­vide even high­er amounts of reli­a­bil­i­ty. It pro­vides more read­ings for a wider range of mate­ri­als and angles not for­mer­ly fea­si­ble. It also has repeat­able feed­back to the robot con­troller regard­ing part posi­tion. These fea­tures bring increased per­for­mance to the pro­duc­tion line. When the focal point is reached, the point laser pro­vides input to the robot.

Reduced Cycle Time

The cycle time is reduced because there is no more need to cut the wire between welds while also being able to search at faster speeds as there is no more weld wire to bend.

Point Laser

Accu­Fast II uses a point laser that search­es and detects the work sur­face when the laser reach­es its pro­grammed focal point. It is sim­i­lar to touch sens­ing as the pro­gram­ming uti­lizes the same macro-jobs, how­ev­er Accu Fast II is non-con­tact and sig­nif­i­cant­ly faster.

Thin­ner Parts

Users are pro­vid­ed with the option of Accu­Fast II for thin­ner parts and to detect square butt joints with a mod­est gap. An edge detect macro rou­tine pro­vides gap width mea­sure­ment. It can also find inside and out­side cir­cles and arcs. 

High Com­pat­i­bil­i­ty

It is com­pat­i­ble with a vari­ety of mate­ri­als and imper­vi­ous to ambi­ent light­ing and most sur­faces (reflec­tive sur­faces may decrease per­for­mance). Fur­ther, Accu­Fast II has built-in jobs for dif­fer­ent joint types. The touch sens­ing option can be com­bined with Accu­Fast II to detect joints that may have optic interference.

Pro­tect­ed Sensor

The sen­sor is enclosed in a hous­ing with pneu­mat­ic shut­ter door and pos­i­tive air pres­sure to pro­tect it form weld spat­ter and fumes. The laser ampli­fi­er is housed in a steel enclo­sure that is mount­ed to the upper arm of the robot. Its design allows set­tings to be made and adjust­ed with­out open­ing the enclo­sure. The ampli­fi­er is pro­tect­ed from the weld environment.

Easy to Retrofit

The Accu­fast sen­sor uses the same input and out­put sig­nals as tra­di­tion­al touch sense mak­ing it easy to retro­fit into exist­ing robot instal­la­tions. If nec­es­sary, Accu­Fast II can be com­bined with ComArc thru-arc seam track­ing for con­toured parts or long seams that may dis­tort while welding.

Sim­ple Programming

Macro job rou­tines sim­pli­fy pro­gram­ming by pro­vid­ing a sin­gle instruc­tion in the robot job for detect­ing a seam or fea­ture. Macro job rou­tines are pro­vid­ed to auto­mat­i­cal­ly detect three sur­face loca­tions then cal­cu­late the radii and cen­ter point offset.

Auto-Teach fur­ther helps to make the pro­gram­ming of the sen­sors easy and accu­rate as it helps deter­mine the opti­mal search direc­tion per­pen­dic­u­lar to the work sur­face. It will auto­mat­i­cal­ly find the taught part loca­tion and the part ori­en­ta­tion. The robot will search per­pen­dic­u­lar to the joint wall, even if the part is posi­tioned at an angle.
