Abstract
A method of and a device for metering a solder wire to a solder location in which an electric motor for driving solder wire feed means supported on a carriage of a solder wire metering device is actuated to provide for feeding a predetermined length of the solder wire to a soldering location, a magnitude of a mechanical feed force appliced to the solder wire is controlled in proportion to a magnitude of a contact pressure force acting on an end of the solder wire at the soldering location, and the electric motor is stopped after the predetermined length of the solder wire has been melted.
Claims19
A method of metering a quantity of a solder wire and comprising the steps of:
- actuating an electric motor for driving solder wire feed means supported on a carriage of a solder wire metering device to feed a predetermined length of the solder wire to a soldering location;
- controlling a magnitude of a mechanical feed force applied to the solder wire in proportion to a magnitude of a contact pressure force acting on an end of the solder wire at the soldering location;
- and
- stopping the electric motor after the predetermined length of the solder wire has been melted at the soldering location.
A device for metering a solder wire of a predetermined length to a solder location, said device comprising a carrier having guide means;
- a carriage displaceable along said guide means in a direction of feeding of the solder wire;
- solder wire feed means mounted on said carriage;
- and spring means extending between said carrier and said carriage for biasing said carriage to a predetermined initial position thereof relative to said carrier and against a contact pressure force applied to an end of the solder wire at a soldering location.
A device for metering a solder wire and comprising a carriage;
- solder wire feed means for feeding the solder wire to a soldering location;
- transmitter means for sensing a contact pressure force acting on an end of the solder wire at the soldering location;
- an electric motor for driving said solder wire feed means;
- and a regulating circuit for controlling operation of said electric motor in accordance with the pressure contact force acting on the solder wire at the soldering location.
