Component Transfer Device

Abstract

To provide a component conveying device flexibly adaptable to conveyance of various kinds of components.SOLUTION: With regard to one aspect of the present invention, a component conveying device for advancing or retreating a component in a first direction comprises a table on which the component is placed, and a repetition driving unit for repetitively moving the table onto a rear side in the first direction. The repetition driving unit comprises a linear motion guide for regulating a movement direction of the table to the first direction, and a conversion unit for converting movement in a rotation direction with a motor into movement in a flat surface direction along a first flat surface including the first direction and transmitting the same to the table. According to the component conveying device, the component is moved in the first direction by a difference in speed change between before and after repetitive movement in the first direction that is given to the table from the repetition driving unit.SELECTED DRAWING: Figure 1
