PURPOSE:To reduce working cost by placing plural needle materials an aggregate on a table, and also, recognizing the position of the needle materials by an image pickup means, and subsequently, moving relatively a laser beam optical axis and a needle material axis center and executing the hole working of the needle material. CONSTITUTION:Plural needle materials 1 are contained in a container 2 so that its origin end faces 1b become the same direction, and the needle material 1 are placed as an aggregate B on a table 3. Subsequently, a camera 12 is placed on the upper part of a half mirror 9 as an image pickup means of the needle material aggregate B, and hole positions of the origin end faces 1b of the needle materials 1 are brought to image pickup separately through a part of a laser beam 8 and stored. Also, in accordance with the position of the needle material 1 which is recognized, a laser beam optical axis and a needle material axis center are moved relatively and in a state that the optical axes coincide with each other, hole working is executed to the origin end face 1b of the needle material 1. Since the hole working of the needle material 1 can be executed quickly and exactly by eliminating entirely the requirement for human intervention, the piercing cost of the needle material is reduced. |
