Abstract

A component mounting device includes: a holding body, pressing mechanism to press the holding body to move on a given route, position detector to detect a position of the holding body, and controller to control the mechanism. The route including: a start position of the holding body at which an insertion pin held by the body is separated from an insertion hole of a substrate, a first position range wherein the insertion pin is partially inserted, and a section position range wherein the insertion pin is fully inserted. When the holding body is pressed by a first pressing force to move on the given route from the start position toward the second position range, the controller controls the pressing mechanism to press the holding body by a pressing force different from the first pressing force, when the holding body stops at a position before or within the first position range.

First claim

1 . A component mounting device configured to insert an insertion pin of a component having the insertion pin into an insertion hole of a substrate and mount the component to the substrate, comprising:
a holding body configured to hold the component; a pressing mechanism configured to press the holding body to move the holding body on a given route; a position detector configured to detect a position of the holding body on the given route; and a controller configured to control the pressing mechanism based on the position of the holding body detected by the position detector, wherein, on the given route, a position of the holding body at which the insertion pin of the component held by the holding body is separated from the insertion hole of the substrate is a start position, a position range of the holding body at which the insertion pin of the component held by the holding body is partially inserted into the insertion hole of the substrate is a first position range, and a position of the holding body at which the insertion pin of the component held by the holding body is fully inserted into the insertion hole of the substrate is a second position range, and wherein in a case where the holding body is pressed by a first pressing force to move on the given route from the start position toward the second position range, the controller controls the pressing mechanism to press the holding body by a pressing force different from the first pressing force, when the holding body stops at a position before or within the first position range.

2 . The component mounting device of claim 1 , wherein the controller controls the pressing mechanism to press the holding body by a second pressing force larger than the first pressing force, when the holding body stops within the first position range.

3 . The component mounting device of claim 1 , further comprising a groping mechanism configured to perform a groping operation in which the component held by the holding body is relatively moved with respect to the substrate in a direction parallel to the substrate so that the component gropes the insertion hole of the substrate,
wherein when the holding body stops before the first position range, the controller controls the groping mechanism to perform the groping operation, while controlling the pressing mechanism to press the holding body by a third pressing force smaller than the first pressing force.

4 . The component mounting device of claim 3 , wherein the controller controls the groping mechanism so that a locus of the holding body draws a plurality of parallel line groups within a given area, when seen in the pressing direction of the pressing mechanism.

5 . The component mounting device of claim 1 , wherein the position detector successively detects the position of the holding body on the given route.

6 . The component mounting device of claim 1 , wherein a position of the holding body at which the holding body that does not hold the component contacts the substrate is a third position range, and
wherein in a case where the holding body is pressed by the first pressing force to move on the given route from the start position toward the second position range, the controller outputs an error signal when the holding body stops within the third position range.

7 . A method of controlling a component mounting device configured to insert an insertion pin of a component having the insertion pin into an insertion hole of a substrate and mount the component to the substrate,
wherein the component mounting device includes: a pressing mechanism configured to press a holding body configured to hold the component to move the holding body on a given route; a position detector configured to detect a position of the holding body on the given route; and a controller configured to control the pressing mechanism based on the position of the holding body detected by the position detector, wherein, on the given route, a position of the holding body at which the insertion pin of the component held by the holding body is separated from the insertion hole of the substrate is a start position, a position range of the holding body at which the insertion pin of the component held by the holding body is partially inserted into the insertion hole of the substrate is a first position range, and a position of the holding body at which the insertion pin of the component held by the holding body is fully inserted into the insertion hole of the substrate is a second position range, and wherein in a case where the holding body is pressed by a first pressing force to move the holding body on the given route from the start position toward the second position range, the controller controls the pressing mechanism to press the holding body by a pressing force different from the first pressing force, when the holding body stops at a position before or within the first position range.
