SAB 40/3000 Lead-frame deflashing machine

Lead frames are loaded continuously onto the belt conveyor. The conveyor transports the lead frames through the deflashing chamber with the suction blast guns mounted on either side of the conveyor. Cams on the conveyor prevent the lead frames from slipping on the conveyor. The lead frames then pass through a blow-off zone where air  nozzles remove deflashing medium still adhering to the lead frames. Key benefits – Proven, high-capacity machine design for fully automatic operation and fast return on investment (ROI). – Low-maintenance, dry deflashing system, little force exertion thanks to use of low pressures, consistently operating injector nozzles, little wear and easy operation – System capacity of up to 1800 lead frames per hour – Precise edge-to-edge deflashing, with masking where required to prevent damage to plastic packaging – Adjustable guide rails to accommodate lead frames of various dimensions – Suitable for all deflashing media typically used in this application, such as thermosets, polyamides and other plastic deflashing media, natural deflashing media deriving from nutshells or fruit stones, powdered brass, etc.

Loading and unloading systems

The loading module permits loading of the lead frames via a magazine. The process is monitored by sensors. The lead frames are fed to the belt conveyor successively at regular intervals, and as soon as the magazine is empty, the operator is alerted. Lead frames are fed manually through the loading aperture at regular intervals. The length of the intervals is specified by a sensor and a display.

Automatic loading and unloading

The loading module serves for automatic, successive loading of lead frames from magazines (buffer magazines supplied by the customer) onto the belt conveyor. The module is equipped with additional lead-frame storage capacity to permit smooth and continuous operation while an empty buffer magazine is being replaced. The unloading and restacking module transfers the lead frames discharged from the machine into an empty magazine.
