Optimized automation systems for all kind of direct imaging processes.

V2 LDI automation for Legend Printers

The V2 – LDI Loader / Unloader has been designed to drastically reduce human intervention in the loading and unloading process of a Legend Printer.

The V2-LDI is designed to feed solder mask panels separated by with plastic sheets, being able to load, flip and unload panels of different sizes avoding touching the functional area of the PCB.

The machine is equipped with an integrated turning and a damp automatically adjustable to the size of the panel.

The Loader / Unloader V2-LDI is fully integrated into the Legend Printer and is equiped with a task manager capable of managing work queues in a simple and user-friendly way.

The design of our LOADER/UNLOADER LDI-V2 grants a full-time operation of the Legend Printer

This automation will be able to cover with full guaranties the loading and unloading of the Legend Printer machine even with single panels jobs. This mean the automation and the Legend Printer are fully connected and able to change jobs without the need of  manual intervention.

Main advantages of the TECHNOSYSTEM LDI-V2 in front of competitors are:

  • Reduced foot print. Technosystem only requires 1,1m at the side of the Legend Printer.
  • High speed performance, less than 19.5 seconds per cycle including roller cleaning, flipping alignment and placing in Legend Printer table.
  • No need to identify the size of the panel. This makes preparation of the loader very easy requiring very short preparation time.
  • Cero position of the panel can be in any corner of the panel, selected by customer.
  • Automatic alignment of 100% of the panels before loading  into the Legend Printer table. This assures perfect alignment on the Legend Printer table and no alignment failures.

Sequence of the TECHNOYSTEM V2 - LDI for Legend Printer.

  1. Top L rack Nº1 is loaded with discrete batches of panels. Each batch can contain a single or multiple panel . Batches are separated by a plastic interleave. Every time the Automation detects a Plastic Sheet the Job to be printed will change to the following one on the Job List. Optional way of operation : All panels are separated by a plastic interleave and automation will change the job to be printed identifying the bare code or data matrix in each panel or in the dummy panel in front of every job.
  2. Data for each batch and quantity per batch is entered into the front end of the Techno System V2- LDI , which is fully synchronised with eh legend printer.
  3. The Legend Printer start is initiated followed by the Loading devise.
  4. The Loader collects side A of the first batch, placed into the Legend Printer , at the same time the Automation sends the trigger of the job to be printed.
  5. The Legend Printer aligns and starts printing.
  6. During the Printing process the Loader collects the next panel from the L rack , rotates the panel uppermost and moves to the ‘place’ position above the Legend Printer table table waiting for the table arrives to the parking position.
  1. When the Legend Printer finishes printing the robot arm lifts the printed panel (with second griper) rotates and lowers the second panel side A into the Legend Printer..
  2. The robot arm moves to the Second L rack and locates the first panel side A.
  3. The next panel from L rack Nº1 is now picked up and moved to the Legend Printer table.
  4. Sequence 7-9 is repeated until all boards have been removed from the L rack Nº1 , printed and placed into L Rack Nº2 ( Now all sides A have been Printed)
  5. The robot arm now proceeds to collect a panel from L rack Nº2 , placing it into the flipping device. The panel has now been flipped and robotic arm collects the panel and moves it to the Legend Printer table.
  6. The sequence is repeated until all panels are printed and located into L Rack Nº 2
  7. All panels are now printed and returned to the L rack Nº1 in the same location and with the same plastic sheets in between panels that where placed initially by the operator.

Adapted to the individual needs of the user in terms of space requirements, process speed and the available hardware and software, optimizing the throughput time in the customer’s circuit board production.
