  1. US ATLAS ITk Pixel Workshop3-5 Sept 2019 Jigs and Fixtures design for 19-0 and 19-1 Stuart Metcalfe 8/29/19 Marco Oriunno

  2. Single Module loading jigs on Fixture Plate Fixture Plate Handling Frame with top cover removed Handling Frame secured to and aligned with plate using 4x shoulder bolts SA-256-102-00/00 Config: Single Module Jigs Single Module loading jigs Central disc with alignment dowels Fixture Cradle alignment pads

  3. Single Module loading jig (prototype) Loctite EA9394 Vacuum connection to hold modules securely to underside of pads SA-256-102-31/00 Pickup pads for the prototype (19.0) are flat. Pads for 19.1 will be re-profiled to accommodate modules Single Module loading jig with top cover raised showing vacuum passages Status: Design is complete Items are being manufactured, one in Lexan, one in aluminum

  4. Pickup Plate (prototype) 3x micrometer height adjustment Jig alignment pads Jig alignment dowel Modules placed on Pickup Table, each aligned along two edges Vacuum connections to hold modules securely in position after placement SA-256-102-27/00

  5. Carrying jig from Pickup Plate to Glue Plate Modules are attached to underside of jig by vacuum Alignment is maintained

  6. Carry modules to Glue Plate Single Module loading jig Jig removed revealing 3x modules located with a precision of ~0.05mm SA-256-102-64/00 Glue Plate – mounted on robot See presentation on Glue Procedure Glue will be applied to a thin sheet of glass or similar before placing the modules

  7. Quad Module loading jigs on Fixture Plate Quad Module loading jigs Same loading process for the Quad module jigs which are designed but not yet manufactured SA-256-102-00/00 Config: Quad Module Jigs

  8. Inverted Handling Frame View showing Ring and Handling Frame inverted and rotated 18°to bond the other side. Cooling tubes pass between Loading Jigs

  9. Fixture Plate with alignment tooling

  10. Central alignment tooling Alignment dowels with single module jigs Alignment dowels with quad module jigs

  11. Prototype Loading procedure summary • Place modules on Pick-up Plate, align to edges • Turn on vacuum pump to secure modules • Place Loading Jig onto modules – initially use Lexan version for visibility • Turn on vacuum in Loading Jig • Turn off vacuum in Pickup table • Mount Glue Plate on robot, verify coordinate system • Apply glue to Glue Plate • Lift Loading Jig off Pickup Plate • Place Loading Jig on Glue Plate • Turn off vacuum in Loading Jig • Wait xx seconds then lift off Loading Jig • Repeat multiple times to refine process, timing, glue loading, release height etc.

  12. Loading procedure summary • Place Handling Frame (HF) on fixture plate – guide cooling tubes through slot in plate • Remove top cover (bottom cover stays in place) • Insert tie down straps in 4 places to secure dowel pins • Secure and align HF with shoulder bolts • Place modules on Pick-up Plate, align to edges • Turn on vacuum pump to secure modules • Place Loading Jig onto modules – initially use Lexan version for visibility • Turn on vacuum in Loading Jig • Turn off vacuum in Pickup table • Mount Fixture Plate on robot, verify coordinate system • Apply glue to Ring • Lift Loading Jig off Pickup Plate • Place Loading Jig on Fixture Plate • Turn off vacuum in Loading Jig

  13. Summary • Single module Jigs are being manufactured – one in Lexan, one in aluminum. They are due at SLAC this week • Assemble the jigs and test/develop the process • Design of quad module jigs, Fixture Plate and center core is complete. Detail drawings will be produced when designer becomes available. Manufacture will follow. • Design pickup plate for quad module jigs • Refine module loading procedure • Practice prototype loading (Aidan) • Measure loaded modules with CMM (Carina) • Measure thermal performance (Sam) • Update tooling drawings for 19.1 i.e. pickup pads will require additional machining and possibly rerouted vacuum pipes • Update models for production tooling • Manufacture production tooling

  14. Backup slides Side and end views of the single module jig on the glue plate

  15. Backup slides Is a single hole sufficient in each of the pads? If module is not in full contact with the pad, machine a pair of slots Request a tapped hole feature in the Handling Frame between the pins to lightly clamp the pins in place during loading
