DMA – Auto advanced automatic scewfeeding system

DMA – Auto advanced automatic scewfeeding system

The DMA auto advanced screwfeeding system is designed for high production speeds. It is also extremely robust, totally comfortable to use, silent and vibration-free.
By repeatedly delivering each screw to the assembly tool head, the automatic screw feeder system provides significant time savings, in particular on the operator cycle.

Description of DMA – Auto advanced automatic scewfeeding system

Operating mode:
The DMA automatic screw feeds include a hollow rocker arm type feeder that selects and directs the screws before transferring them to a gravity rail down to the separator.
From there, a screw is blown into the pipe to the assembly head each time the screwdriver sends a request. In parallel, a new screw is separated and transported through the blow tube.
The screw is kept above the screw head mandrel by mechanical shutters to make it easier to pin it onto the part.
The continuous pressure of the operator on the screwdriver start control causes the pneumatic telescope to push the screwdriver bit into contact with the screw and follow it through the complete assembly into the part.

Product plus:
The DMA auto advanced automatic screwfeeding system is ideal for assembling fragile parts: as the head mandrel does not touch the part, you can use it without any additional protection.

Screw compatibility:
The accepted screw dimensions vary from a body diameter of 2.3 to 6 mm and a body length of up to 22 mm.
The total head diameter / length ratio should ideally be 1.5.  
For smaller, larger or longer screw dimensions, the rocker arm system can be replaced by a vibrating bowl (feasibility study needed).
