Automation Manager used to Assemble Mobile Devices
What:
Assembly of many of today's devices requires precise alignment. Connectors are small and intricate
and their location prior to being "pressed in" requires this precise alignment
Advantages/Benefits. :
- Automation Manger is very flexible and can integrate diverse hardware very quickly , in this case 5 axis are being controlled integrating two different motion controls in the same machine
- Integrating multiple cameras
- controlling all digital io on the machine ie the cycle start, vacuum, part presence sensors and limit sensors.
NOTE no PLC is used - A workflow instructs the operator of the steps as he inserts the phone and runs the machine
- Tailored user interface to customer needs
- Ability to run the machine to the user defined tolerance and press force configurations
Automation Manager Features Used :
- Event Logging
- Product Counting
- Workflow operator guidance
- Image logging of faulty parts
- Motion Control interface provides a DRO (Digital Read Out) for each controller and the interface to manually move the axis in maintenance mode
Hardware :
- Advantech IO card
- Coolmuscle and UIRobot (UIM 214) motion devices (both controlled via usb serial interface)
- UEye usb cameras
- Basic Computer
Operation :
On Assembly lines of phones operators place the phone on the device.
The machine then
- brings the device under the camera(s)
- if required any protective foils are removed by the motion of an axis
- performs the vision analysis to determine the alignment offsets
- performs the alignment
- verifies the device/connector are correctly aligned
- operate the downward axis the press / exert the precise force to make the connection
Monitoring:
- Monitor vacuum conditions through the processes
- Ensure the axis and operator are safe at all times
Typical System Performance :
- Inspection time msec
- complete cycle time, ie Align and press typically 20-40sec
