Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 全ラインに渡って正確かつ迅速な補正を可能 とする。 【構成】 トラッキング上での溶接点と実溶接点とのズ レ量を演算するズレ量演算手段21と、ズレ量を時系列 的に記憶するズレ量履歴記憶手段23と、位置合わせ指 示がされた場合に、位置合わせ定点とのズレ量を修正量 として演算する修正量演算手段24と、前記修正量演算 手段24で求められた修正量とその上流側特異点の修正 量との差分が予め設定されている一定値αより小さい範 囲であれば、この修正量と同一の補正を実行する一方、 一定値αより大きい範囲であれば、比例配分により補正 量を決定して実行する補正量決定手段25とを具備す る。 (57) [Summary] [Purpose] It enables accurate and rapid correction over the entire line. [Arrangement] A displacement amount calculating means 21 for calculating a displacement amount between a welding point and an actual welding point on tracking, a displacement amount history storing means 23 for storing the displacement amount in time series, and an alignment instruction. In this case, a correction amount calculation means 24 for calculating a deviation amount from the alignment fixed point as a correction amount, and a difference between the correction amount obtained by the correction amount calculation means 24 and the correction amount of the upstream singular point is set in advance. If the range is smaller than the given constant α, the same correction as this correction amount is executed, If the range is larger than the constant value α, the correction amount determining means 25 for determining and executing the correction amount by proportional distribution is provided.
