COMPONENT MOUNTING DEVICE AND STATE DETERMINATION METHOD

To provide a component mounting device capable of suppressing deterioration in inspection accuracy of a failure of a tape feeder independent of the number of components installed in the tape feeder.SOLUTION: A component mounting device that feeds a carrier tape in which a component is housed in a feed direction by a tape feeder, and in which a component fed to a component fetching out position is held and mounted to a substrate, comprises: a sprocket that feeds the carrier tape in a feeding direction; a component transfer motor that rotates and drives the sprocket; a first storage part that stores a slide failure determination value of the component transfer motor corresponding to a residual number of components remained in the carrier tape; a second storage part that stores the residual number of components remained in the carrier tape when rotating and driving the sprocket by the component transfer motor; a measurement part that measures a first current value of the component transfer motor when rotating and driving the sprocket by the component transfer motor; and a determination part determining that the component transfer motor is in a slide failure in the case where the first current value measured by the measurement part is larger than the slide failure determination value stored in the first storage part corresponding to the component residual number stored in the second storage part.SELECTED DRAWING: Figure 6 【課題】テープフィーダに設置された部品の個数に依存せずに、テープフィーダの故障の検出精度の低下を抑制できる部品装着装置を提供する。【解決手段】テープフィーダにより部品を収納したキャリアテープを送り方向に送り、部品取り出し位置に送られた部品を保持し基板に装着する部品実装装置であって、キャリアテープを送り方向に送るスプロケットと、スプロケットを回転駆動する部品搬送モータと、キャリアテープに残る部品残数に対応した部品搬送モータの摺動不良判定値を記憶する第１の記憶部と、部品搬送モータがスプロケットを回転駆動する際のキャリアテープに残る部品残数を記憶する第２の記憶部と、部品搬送モータがスプロケットを回転駆動する際の部品搬送モータの第１の電流値を計測する計測部と、計測部によって計測された第１の電流値が、第２の記憶部に記憶された部品残数に対応する第１の記憶部に記憶された摺動不良判定値より大きい場合、部品搬送モータが摺動不良であると判定する判定部と、を備える。【選択図】図６
