Same Cell – Several Applications

 

1Key Technologies

 

Dispensing

Pick and Place

Driving Screws

Vision Inspection

Bar Code Scanning

Labeling

Clinching

Packaging

Laser Marking

Height Detection

Press Applications

Test/Special Application Handling

Dispense Weight Monitoring

 

Verified Machine Accuracy

 

 

Every Polaris positioning system is mapped enabling the user to translate CAD files

The Polaris can be measured using traceable glass boards and components

Final placement performance for a Servo Gripper or Multi-Process Pick and Place machine is: “X”, “Y” +/- 75 micron @ 4σ; Theta +/- 0.2° @ 4σ; X, Y, & Z repeatability +/- 0.01mm

 

Multi-Process Interface

 

Standard tool interface allows Polaris to be a platform across multiple work cells (final assembly, odd form, packaging, screw driving, dispensing, etc.)

Various tools can be used in combinations to achieve custom process requirements

Modular system and use of standard interfaces results in a cost-effective solution by paying only for needed capability

Common software interface with all options

 

Multi-Process Tools/Heads

Vision guidance camera

Quadrus 2-D bar code scanner

Cognex insight color inspection camera

Keyence color inspection camera

Vacuum and gripper pick and place tools (pneumatic and servo)

Dispensing valves

Screw drivers

Height detector

Future applications driven by customer requirements

 

Screw Driving Head

 

The head is mounted on the rear of the multi-Process head to conserve a location on the front

The screw driver that is implemented here is a Deprag, electric drive

In an effort to conserve space, this driver was re-packaged specifically for Polaris

 

Dispense Path Programming

 

Program the machine using the database and the pre-defined shapes

– Speed, acceleration, deceleration, dwell can all be programmed off-line

Look at a dynamic view of the dispense path

– Gross programming errors will be caught before any material is wasted using this view

Check the path on the machine before dispensing any product

– The downward looking camera will drive through the programmed path

 

Weight Scale – Dispense option

 

The scale can be mounted anywhere on the base frame

Provides the user with the weight of a programmed amount of material

The scale is primarily used as an audit process during normal production

The user controls the number of cycles between audits

 

Non-Contact Needle calibration

 

This dispensing option provides for automatic calibration at the users request or when changing the needle

This option eliminates lengthy manual steps to define the new x,y,z coordinates

If the material has a tendency to to adhere to the bottom or outside of the nozzle, an optional cleaning station is available

 

Inside the Machine – Downward Looking Camera

 

Allows fiducials or holes to be used for orientation

Programmable light levels

Also enables flexible feeder teaching

1415

 

Inside the Machine – Upward Looking Camera

 

GSM OFA-style camera

Software supports pattern recognition for through-hole leads and final assembly components

Programmable light levels

Enables CAD-driven placements without adjustment

 

Material Handling – Triple stage product handling

 

Provides for a Board in a stage closer to the “Work” area of the machine

Edge-belt conveyor accepts up to 457 mm x 508 mm (18” x 20”) boards or pallets

Optional programmable width control (PWC) and tooling pin registration

None Required! – The machine is modular and can accept non-Universal product handling or simply a work surface for stand alone applications
