PURPOSE:To ensure confirmation of the co-ordinates, by providing an XY-movement measuring device on an XY-movement table constituting a bonding device, adding the signal therefrom to an operating device at every completion of one stroke, and comparing the signal with predetermined position information. CONSTITUTION:A bonding head 13 is mounted on an XY table 11, from which a bonding arm 12a is protruded so that it can move up and down on a support 12d. A bonding tool 12, at the end of which a wire is pierced is provided. Under the table 11, a linear encoder head 21 and a linear encoder scale 22 are provided, and the output therefrom is sent to a measuring device 23 where the local co-ordinates are obtained. Then, the co-ordinates are compared with a specified co-ordinates values in an operating device 24. Thereafter, a pulse motor 16 is operated by the output via an output device 25 for a compensating amount of movement. The table 11 is moved with the co-ordinates being confirmed by an optical sensor 18 and an original-point-confirming cam 17, thereby the position is controlled at every completion of a stroke. |
