1. IPD Technical Conference February 19 th 2008 Automotive Electronics Shock Absorber Inspection Ohio Office

2. Company History  This Ohio based customer molds various silicone rubber parts for the automotive and transportation industry.  Their initial vision systems were based upon the original NetSight NS-1000 and the JAI CV-A11 camera.  They have since migrated to the VA-40 with the higher resolution JAI CV-A1 and CV-A2 cameras. How many remember this?

3. The Application  Inspect an aluminum shock absorber plate that protects the ABS electronics module used in a vehicle.  The plates are shipped to our customer and they mold the silicone rubber pyramids to the plate.  Six plates are molded at one time.

4. The Application  Verify mounting tab is in the top left corner.  Check silicone pyramids for correct size and shape.  Verify vent hole is present.  Separate output indicating which mold cavity made the faulty part. (Variable Assignment Equations)

5. iNspect Tools Used  Match Tool detects tab presence  Circle Tool calculating Circularity and minimum Radius  Count Tool finds the vent hole.

6. Part Presentation A robotic arm loads the mold with six aluminum plates. After molding the robotic arm picks up the six parts and indexes them in front of the camera.

7. Vision Equipment  VA40E-04 Running iNspect  JAI CV-A2 Megapixel Camera  Kowa 18-108 Macro Zoom lens  Custom blue LED dome light built around Nerlite LALL 22x288 light lines This simple vision application did not require the use of VA40E-04, A2 camera, and zoom lens, but this configuration assures spare parts uniformity with their other vision systems.

12. Variable Assignment Equations  Post Image Process plate_counter = plate_counter+ 1 if (plate_counter= 1) plate_1_status = Result.0 if (plate_counter= 2) plate_2_status = Result.0 if (plate_counter= 3) plate_3_status = Result.0 if (plate_counter= 4) plate_4_status = Result.0 if (plate_counter= 5) plate_5_status = Result.0 if (plate_counter= 6) plate_6_status = Result.0 if (plate_1_status= 1) FAIL = 0 if (plate_1_status!= 1) FAIL = 1 if (plate_2_status!= 1) Global.GPO[3] = pulse( 1,0,1000) if (plate_3_status!= 1) Global.GPO[4] = pulse( 1,0,1000) if (plate_4_status!= 1) Global.GPO[5] = pulse( 1,0,1000) if (plate_5_status!= 1) Global.GPO[6] = pulse( 1,0,1000) if (plate_6_status!= 1) Global.GPO[7] = pulse( 1,0,1000) 2.) Create Six Status Registers here 1.) Create Plate Counter here 3.) Assign Status Registers to separate outputs here

13. Variable Assignment Equations  Batch Reset plate_counter = 0 Global.GPO[1] = 0 Global.GPO[3] = 0 Global.GPO[4] = 0 Global.GPO[5] = 0 Global.GPO[6] = 0 Global.GPO[7] = 0 plate_1_status = 1 plate_2_status = 1 plate_3_status = 1 plate_4_status = 1 plate_5_status = 1 plate_6_status = 1 FAIL = 0 PASS = 1 4.) Create User Function here to reset registers and outputs. (This User Function serves as a subroutine.)

14. Variable Assignment Equations  Solution Initialize BatchReset( )  Post Image Process if (plate_counter>= 6) BatchReset( ) 5.) Add the User Function to prepare for the next batch.

15. Variable Assignment Equations  Solution Initialize BatchReset( )  Post Image Process if (plate_counter>= 6) BatchReset( ) plate_counter = plate_counter+ 1 if (plate_counter= 1) plate_1_status = Result.0 if (plate_counter= 2) plate_2_status = Result.0 if (plate_counter= 3) plate_3_status = Result.0 if (plate_counter= 4) plate_4_status = Result.0 if (plate_counter= 5) plate_5_status = Result.0 if (plate_counter= 6) plate_6_status = Result.0 if (plate_1_status= 1) FAIL = 0 if (plate_1_status!= 1) FAIL = 1 if (plate_2_status!= 1) Global.GPO[3] = pulse( 1,0,1000) if (plate_3_status!= 1) Global.GPO[4] = pulse( 1,0,1000) if (plate_4_status!= 1) Global.GPO[5] = pulse( 1,0,1000) if (plate_5_status!= 1) Global.GPO[6] = pulse( 1,0,1000) if (plate_6_status!= 1) Global.GPO[7] = pulse( 1,0,1000) Putting it all together
