The models HD806 and HD812 were developed for the fast and highly precise assembly of LEDs in large batch sizes. These models are connected to an optical centering system, which enables image processing to scan over a stationary camera.
True fly over alignment
The brand new high-speed linear drive portal of the 6-head HD806 / HD812 enables the simultaneous detection of up to 30,000 LEDs per hour (according to the IPC-9850 standard). True Fly Over alignment with the camera facing up between the feeder base and the PCB aligns the components while the head is in motion. Thanks to the supplied software, the feed positions are optimized before placement in order to minimize the stroke of the head and the tool change.
Flexible circuit board strips, round LED light bulb boards and irregularly shaped boards can be installed quickly, precisely and reliably on all models of the HD series. For long LED tubes, the model HD812 offers a maximum board size of 1200 mm. (The HD806 model offers a maximum board size of 600 mm.) In all models, the boards are manufactured in one pass to achieve maximum efficiency and throughput.
The HD806 / HD812 is supplied as standard with a work table and a magnetic board holder or can be configured for line automation with an SMEMA-compatible inline conveyor belt at the time of purchase.
The HD806 / HD812 offers non-stop production. The ability to automatically switch to another feeder when an operating feeder runs out of components enables the operator to refill and replace the empty feeder without even taking production offline.
The HD806 / HD812 can accommodate up to 16 tape feeders. These special servo feeders use brushless motors for a longer feeder life under production conditions around the clock. With these feeders it is also possible to split a new roll onto an old roll in order to minimize production interruptions.
Especially for LED
In contrast to standard automatic placement machines, which have been adapted to the LED assembly, the HD806 / HD812 is specially built for this purpose, so that it can do one thing - the assembly of LED boards - really well.
The HD806 / HD812 places LED components from 0402 to 20 mm x 18 mm, including standard and irregularly shaped LEDs for small connections or resistors
Each of the six placement heads of the HD806 / HD812 has positive air pressure to blow off "sticky" LED components. Non-stick coated Teflon® nozzles - including custom nozzles - are also available. Curved LEDs can be securely placed using special nozzles that are designed so that they do not come into contact with the optical lens during pick-up and placement, thereby protecting the overall light output and reliability of the component.
