Abstract
In a nozzle distance confirming device and a method of nozzle distance confirmation, first, a nozzle distance confirming member together with an exchange section is attached to a tip section of a nozzle main body. Next, a tip section of a needle is caused to abut on the nozzle distance confirming member, whereby the nozzle distance confirming member is exposed from the exchange section and brought into contact with a workpiece. Next, a position of the needle is detected by an eddy current sensor.
Claims6
A nozzle distance confirming device for confirming a distance between a nozzle and a workpiece, comprising:
- a needle configured to open and close an opening section of a tip of the nozzle;
- a needle advancing and retracting unit configured to advance and retract the needle with respect to the opening section;
- a needle position detecting unit configured to detect a position of the needle;
- and
- a nozzle distance confirming member provided in an attachable manner to the tip of the nozzle, configured to abut on a tip of the needle, and configured to, when confirming the distance between the nozzle and the workpiece, contact the workpiece by being exposed from the tip of the nozzle in a state of having abutted on the tip of the needle.
A method of nozzle distance confirmation for confirming a distance between a nozzle and a workpiece, comprising the steps of:
- attaching a nozzle distance confirming member to a tip of the nozzle;
- causing a tip of a needle to abut on the nozzle distance confirming member by a needle advancing and retracting unit, and thereby exposing the nozzle distance confirming member from the tip of the nozzle to bring the nozzle distance confirming member into contact with the workpiece;
- and
- detecting a position of the needle by a needle position detecting unit.
