Solder dispensing apparatus and method of operation

A solder dispensing apparatus comprising, in combination:

• a casing having a body and a handle;
• a motor disposed within said body, said motor operating a pair of pinch wheels for moving a line of solder through an input tube and an output tube located within said casing;
• a direct current power supply mounted within said handle for electrifying said motor;
• a trigger switch comprised of an on-off switch and a variable potentiometer disposed within said casing for connecting said motor to said power supply and for limiting the speed of said motor;
• a voltage regulator mounted on a printed circuit board and in electrical communication with said motor for maintaining a constant input voltage to said motor;
• a plurality of reduction gears disposed between said motor and said pair of pinch wheels for providing improved speed change sensitivity;
• and
• an extension tip mounted to the forward end of said body and in mechanical communication with said outlet tube for providing improved maneuverability and dispensibility of said line of solder to a designated solder joint.

A solder dispensing apparatus comprising, in combination:

• housing means having a body and a handle;
• driving means disposed within said body, said driving means operating a pulling means for moving a line of solder through a passageway located within said housing means;
• energizing means mounted within said handle for electrifying said means;
• regulating means mounted on a printed circuit board and in electrical communication with said driving means for maintaining a constant input voltage to said driving means;
• reducing means disposed between said driving means and said pulling means having a push button connected to a linkage shaft and a spring-loaded lever arm for disengaging said pulling means for threading said line of solder through said dispensing apparatus;
• and
• extending means mounted to the forward end of said body and in mechanical communication with said passageway for providing improved maneuverability and dispensibility of said line of solder to a designated solder joint.

• replenishing means in mechanical communication with said housing means, said replenishing means comprising a spool disposed on a spool support arm, said spool support arm including a channel for receiving an end of a cranking handle for rotating said spool about said support arm for replenishing said spool with said line of solder;
• and
• extending means mounted to the forward end of said body and in mechanical communication with said passageway for providing improved maneuverability and dispensibility of said line of solder to a designated solder joint.

A method for operating a solder dispensing apparatus, said method comprising the steps of:

• providing a casing having a body and a handle;
• disposing a motor within said body for operating a pair of pinch wheels for moving a line of solder through an input tube and an output tube located within said casing;
• mounting a direct current power supply within said handle for electrifying said motor;
• locating a trigger switch within said casing for connecting said motor to said power supply and for limiting the speed of said motor, said trigger switch comprised of an on-off switch and a variable potentiometer;
• regulating a plurality of input parameters of said motor for maintaining a constant input voltage;
• providing a plurality of reduction gears disposed between said motor and said pair of pinch wheels for improving speed change sensitivity;
• entering a side of said casing through a sliding panel for accessing said pair of pinch wheels and said input and output tubes;
• disengaging said pair of pinch wheels for threading said line of solder through said solder dispensing apparatus;
• and
• extending said output tube with an extension tip mounted to the forward end of said body for providing improved maneuverability and dispensibility of said line of solder to a designated solder joint.
