Description

This invention relates to a component mounting apparatus and a component mounting method for transporting substrates and mounting components. The component mounting apparatus transports the substrate to a stopping position using a transport belt in the substrate transport section, retrieves components from the component supply section with a mounting head, captures images of the components held by the mounting head with a camera positioned between the component supply section and the substrate transport section, corrects the position of the mounting head, and mounts the components onto the substrate at the stopping position (see, for example, Patent Document 1). The component mounting apparatus described in Patent Document 1 includes a first substrate detection sensor that detects the leading edge of the substrate at the stopping position, and a second substrate detection sensor that detects the leading edge of the substrate that has overrun from the stopping position. By controlling the substrate transport section based on the detection results of these two substrate detection sensors, the substrate is accurately positioned at the stopping position.

The configurations, shapes, etc., described below are illustrative examples for illustrative purposes and can be appropriately modified according to the specifications of the component mounting apparatus and substrate transport unit. In the following, corresponding elements are denoted by the same reference numerals in all drawings, and redundant explanations are omitted. In Figure 1 and some parts described later, two mutually orthogonal axes in the horizontal plane are shown: the X-axis (left-right direction in Figure 1) representing the substrate transport direction, and the Y-axis (up-down direction in Figure 1) perpendicular to the substrate transport direction. In Figure 2(b) and some parts described later, the Z-axis (up-down direction in Figure 2(b)) is shown as the height direction perpendicular to the horizontal plane. First, referring to Figure 1, the configuration of the component mounting apparatus 1 will be explained. The component mounting apparatus 1 has the function of performing component mounting work, which involves mounting components supplied from the component supply unit onto a substrate to manufacture a mounted substrate. A substrate transport unit 2 is installed on the upper part of the base 1a, along the X-axis. The substrate transport unit 2 transports the substrate 3, which is brought in from upstream, along the X-axis, and positions and holds it at the mounting work position by the mounting head, which will be described below. The substrate transport unit 2 also transports the substrate 3, after the component mounting work is completed, downstream. A component supply unit 4 is installed in front of the board transport unit 2. Multiple tape feeders 5 are mounted in parallel along the X-axis in the component supply unit 4. The tape feeders 5 feed a carrier tape, which has pockets for storing components, in a pitch direction from the outside of the component supply unit 4 toward the board transport unit 2 (tape feeding direction), thereby supplying components to the component pick-up position where the mounting head picks them up. In Figure 1, Y-axis tables 6 equipped with linear drive mechanisms are positioned at both ends of the upper surface of the base 1a in the X-axis direction. A beam 7, similarly equipped with a linear mechanism, is mo
