Inline Automation DRI

Directly coming from the pre-processes, PCBs are fed to the process system via 6-axis robot systems, processed on both sides with the help of an integrated flip function and automatically fed into line to the follow-up process.

Highlights

  • With a cycle time of 13 sec for the DRS and DRI models incl. 3 sec table change time, capacities of > 2 PCBs/min – processed on both sides
  • Prepared for MES (OPC/UA) connection
  • Handling of up to 6kg printed circuit boards
  • Contactless centering via CCD cameras (very high placement accuracy)
  • No scratching of the LP surface
  • Variable offsets (X, Y and R axis) for all robot positions (pick and place) adjustable in automatic mode
  • Deposit position on LDI/AOI table can be configured rotated +/- 90° and or 180° (cycle time savings for the process machine if necessary)
  • Automatic dummy plate recognition (order separator)
  • The automation reacts state-oriented. Example: In case of loss of a PCB or malfunction of an LDI/AOI with subsequent basic position run, the automation recognizes the new situation independently. Production can be continued seamlessly
  • Logfile creation: alarm history, event history, interface M2M
  • Certified ESD design possible
  • Staggered depositing of IO plates, individually adjustable via HMI
  • Simple manual intervention, without interruption of the running automatic operation
  • Database connection (read and write)*
  • Automatic override adjustment according to LP weight (process reliability)*.
  • Automatic gripper adjustment incl. format check without loss of cycle time*.
  • 100% traceability in log file and database*
  • Job data recording via DMC* on the LP or job list
  • Process control via weight and thickness information*
  • Automatic cleaning of each individual side before processing via non-contact cleaning systems*.
* optional

Description

The PCBs are handled by 6-axis robot 1 from an inclined cassette or a slot cassette to the contact-free camera adjustment. Accurate, if necessary touching only in the edge area, they are placed on the process machine via a reliable gripper system with individual ejectors for each suction cup. After processing the first side the flipping is done by transferring the board from robot 2 back to robot 1. The finished processed PCB is then stored by the second robot on an L-rack or in a slot cassette. In principle automation acts as the master for the process machine. Order data are transferred for each individual PCB to the process machine from the PCB coding or by input into the HMI – manually or via bar code readers. This speeds up the data preparation and the automation can automatically adapt to the different board conditions (size, weight, order change) if necessary. The system can be executed optionally with a cassette for NOKPCBs and with slip-sheet handling.
