DELIVERY OF AUTOMATIC LINE FOR ASSEMBLY OF EGR VALVE USING ROBOTICS

Project Name:                       Assembly line for EGR valve VW T6 LP
Term of implementation:     2018–2020

SPECIFICATION:
The project started based on customer request and step by step improved in subsequent technical negotiations -where the final assignment by the end user.
The main customer request was to improve quality, saving labor and increasing productivity.

SOLUTION:
Cycle time:        50 s / pc
Operator staff:   2

 

PROCESS DESCRIPTION:

  • Loading of valve components by operator on pallet on ST1 including checking of presence and correct insertion of all pieces by vision system.
  • Automatic laser marking of a piece with the DMC code on ST2 including verification of the DMC code using an automatic reader and writing into the traceability system.
  • Automatic cleaning and activation of parts surface using plasma technology on ST2.
  • Automatic application of the functional membrane to the marked position on the HOUSING with verification of the position of gluing using vision systems on ST2.
  • Automatic assembly of SHAFT / C-CLIP / BEARING and its insertion into HOUSING, bearing pressing by servo presses on ST3 and ST4. Parts handling by 6-axis robot.
  • Automatic air leak test over pressed bearings in HOUSING on ST5.
  • Automatic flap assembly, automatic free space adjustment and automatic screwing of the piece on ST6. Parts handling by 6-axis robot.
  • Automatic picking and pressing of DC MOTOR and its subsequent assembly into HOUSING on ST7. Parts handling by SCARA robot.
  • Automatic assembly of SECTOR GEAR into HOUSING, its placement and automatic laser welding on ST8. Welding in argon atmosphere. Parts handling by 6-axis robot.
  • Automatic glue application into SECTOR GEAR by screw feeder, verification of correct application by vision system, activation of glue by UV lamp, automatic magnet installation and subsequent measurement of magnet flatness after installation by profilometer on ST9. Operations are performed on a 6-position turntable.
  • Automatic installation of the INTERMEDIATE GEAR part on ST10. Parts handling by SCARA robot.
  • Automatic assembly of HOUSING using O-RING, subsequent assembly of HOUSING and COVER and each to other fixation using an automatic screwdriver on ST11. Parts handling by 6-axis robot.
  • Automatic air test of valve on ST12.
  • Automatic EOL tester including valve chip programming on ST13.
  • Automatic cap pressing using servo press on ST14.
  • Automatic laser marking of the valve with customer label on ST2.
  • Manual removal of valve from line by operator on ST15. Following semi-automatic assembly of the connection cable using a manual electric screwdriver and an electrical test. Manual storage of the complete VW T6 LP EGR valve in the customer packaging.
