Abstract:
A method of metering out precise doses of soldering wire and comprising the steps of:moving the soldering material back from an operator and passing by a sensor(s) in order to find an end of a soldering wire; reversing a direction of movement of the soldering wire towards an operator and counting a time interval(s), during which the end of the soldering wire passes by neighboring sensor(s); calculating a time duration of the soldering wire mover's activities, by using the results of the previous step as well as an operator's settings; continue moving the soldering wire towards an operator, in accordance with the calculated period of time from the previous step; keeping unmoved the soldering material until a moment when appropriate sensor(s) will register that an operator has picked up, by means of soldering iron, a previously determined dose of the soldering wire; starting a cycle of metering a soldering wire again.
