Computer-controlled dispenser device of fitting systems for surface-mounted components (surface-mounted devices) (SMD fitting systems)

摘要

In the case of a computer-controlled dispenser device of fitting systems for surface-mounted components (SMD fitting systems), a cartridge (20), which accommodates a supply of pasty adhesive (22), and a dispenser head, on which a coupling (especially a luer connection) for detachable connection to the cartridge (20) is constructed, are provided. Located in the cartridge (20) and on the adhesive level (24) (26) is a permanent magnet disc (26) whose magnetic material has a lower specific weight than the pasty-liquid adhesive (22) and is dimensioned such that it has play in all directions with respect to the unobstructed internal cross-section of the cartridge (20) but is axially so long that it always remains essentially on the same axis as the cartridge (20). In addition to the cartridge (20), a holder (34) is provided which accommodates a reed switch (60) which is arranged at an adjustable height and is matched to the magnetic disc (26), and whose contacts can be connected to the computer. <IMAGE>
