PROBLEM TO BE SOLVED: To simplify a device constitution by reducing the number of drive units in use, and dispensing with a sensor and a control circuit, and to surely perform screwing.SOLUTION: This invention relates to a screwing device 6 which attaches a screw 5 to a screwing point 3 of a screwing object 2 installed on a base board 1 by using an electric tool 4. The screwing device comprises a movable pedestal 12 which holds the screwing object 2, and is installed on an upper face of the base board 1 via a two-dimensional guide 11 so as to be movable in plane, and a tool ascending/descending mechanism 13 which ascends and descends the electric tool 4 to/from the base board 1. Furthermore, the screwing device comprises a pedestal moving mechanism 15 which moves the movable pedestal 12 so that the screwing point 3 coincides with a descending point 14 of the electric tool 4 by utilizing a descending motion of the tool ascending/descending mechanism 13.SELECTED DRAWING: Figure 6 |
