Abstract

A melting tool control apparatus comprises a drive mechanism, a melt processing assembly configured to perform a melt process, a receiving module that receives input of three-dimensional coordinate information of a first point where the melt process is to be performed and input of a position information indicating a position different from the first point, and a process control module configured to control the melt processing assembly to perform the melt process when the distal end is at the first point.

First claim

What is claimed is:

1. A melting tool control apparatus comprising:
a drive mechanism configured to move a distal end of a heating tool;
a melt processing assembly configured to perform a melt process forming a solder point at a point on a substrate using the distal end;
a receiving module that receives input of a position of the solder point, the solder point comprising three-dimensional coordinate information of a first point where the melt process is to be performed, and input of a position information indicating a position above a surface of the substrate which is different from the first point; and
a process control module configured to control the melt processing assembly to perform the melt process when the distal end is at the first point,
wherein the drive mechanism is configured to move the distal end between the position indicated by the position information and the first point.

2. The melting tool control apparatus according to claim 1 , wherein
the position information is three-dimensional coordinate information of a second point that is different from the three-dimensional coordinate information of the first point.

3. The melting tool control apparatus according to claim 1 , wherein
the position information includes distance information indicating a distance from the first point and direction information indicating a direction from the first point, and
the process control module determines a position for a second point based on the distance information and the direction information, and causes the drive mechanism to move the distal end from the determined position of the second point to the first point.

4. The melting tool control apparatus according to claim 2 , further comprising the heating tool, wherein
the heating tool is a soldering iron, and
the melt processing assembly performs a principal melt as the melt process when the distal end reaches the first point after moving from the second point, the principal melt process being performed by supplying a principal amount of solder to the distal end.

5. The melting tool control apparatus according to claim 4 , wherein
the process control module further controls the melt processing assembly to perform a preparatory melt process during which a preparatory supply amount of solder is supplied to the distal end when the distal end is at the second point, the preparatory supply amount being less than the principal supply amount.

6. The melting tool control apparatus according to claim 4 , wherein
the process control module controls the drive mechanism to move the distal end to a recede position after completion of the principal melt process, the recede position being at a distance and spaced away from a surface of a substrate on which the principal melt process was performed.

7. The melting tool control apparatus according to claim 4 , wherein
the process control module controls the melt processing assembly to perform a finishing melt process during which a finishing supply amount of solder is by the melt processing assembly to the distal end while keeping the distal end at the first point after completion of the principal melt process, the finishing supply amount being less than the principal supply amount, and
the process control module controls the drive mechanism to move the distal end to a recede position after completion of the finishing melt process, the recede position being at a distance and spaced away from a surface of a substrate on which the principal melt process was performed.

8. A melting tool control apparatus comprising:
a drive mechanism configured to move a distal end of a heating tool;

wherein the position information is three-dimensional coordinate information of a second point that is different from the three-dimensional coordinate information of the first point,
wherein when the process selection module receives the selection of the first process mode, the receiving module receives the first point as an end point to which the distal end is moved and where a solder point is formed, and receives the second point as a start point to which the distal end is moved, and
when the process selection module receives the selection of the second process mode, the receiving module receives the first point as a start point to which the distal end is moved and where drawing of the line segment is started, and receives the second point as an end point to which the distal end is moved and where drawing of the line segment is ended.

9. The melting tool control apparatus according to claim 4 , further comprising
a recede selection module that receives selection between a first recede mode for returning the distal end to the second point after the principal melt process, and a second recede mode for moving the distal end in a direction perpendicular to and away from a surface of a substrate, wherein
when the recede selection module receives the selection of the first recede mode, the process control module controls the drive mechanism to return the distal end to the second point after the principal melt process, and
when the recede selection module receives the selection of the second recede mode, the process control module controls the drive mechanism to move the distal end in the perpendicular direction after the principal melt process.
