Problems solved by technology

[0004] However, if a plurality of heads are arranged in two rows before and after, it is difficult to take a projected image of the elements because the holding elements of the heads arranged in front and behind overlap each other.
[0005] In such a case, the holding elements of the heads arranged in two rows

Abstract

This component imaging device is equipped with: a head unit that has a first row of heads and a second row of heads, each row including multiple heads; an imaging unit for capturing images of components held by the respective heads; a moving means for moving the head unit relative to the imaging unit; and an imagining control means. The imaging unit is equipped with an image sensor and an optical system. The optical system includes a first light-guiding unit for guiding light from a component held by a head of the first row to the image sensor and a second light-guiding unit for guiding light from a component held by a head of the second row to the image sensor. The light path length of the first light-guiding unit is set such that a focused image can be obtained of the component held by head of the first row, and the light path length of the second light-guiding unit is set such that a focused image can be obtained of the component held by the head of the second row. The imaging control means controls the height positions of the respective rows of heads and exposure timing of the image sensor.

Description

technical field [0001] The present invention relates to a component imaging device that captures a component held on a head from the side thereof, and a component mounting device including the component imaging device. Background technique [0002] Conventionally, there is known a component mounting device in which a component is taken out from a component supply unit by a component mounting head and mounted at a mounting position on a board. As such a component mounting device, there is known a device that recognizes the component holding state of the head in advance by photographing the component held on the head from the side of the component before mounting the component on the board. For example, the component mounting device disclosed in Patent Document 1 includes a head unit, and a plurality of mounting heads are mounted on the head unit in a line. The illuminating device irradiates illuminating light from the side, and a camera is fixedly mounted on a supporting mem...
