WORK HEAD MOVING DEVICE

PURPOSE: To move a work head moving device at high speed to an accurate position in a small size and at a lightweight by a method wherein the work head moving device is so constructed that work heads are held on the respective point parts of first and second arms and the first and second arms are rotated in a prescribed range on shafts fixed with the respective arms to move symmetrically to each other. CONSTITUTION: Adhesive-coating work heads are respectively constituted of air cylinders 46 and 56 fixed on the point parts of arms 45 and 55 facing downward, holding member 47 and 57 mounted to pistons of the cylinders 46 and 56, and syringes 48 and 58 fixed to the members 47 and 57. The syringes 48 and 58 are filled with a liquid bonding agent and nozzles 49 and 59 are respectively mounted to the lower ends of the syringes 48 and 58. By pressing the liquid bonding agent with compressed air which is sent through hoses 9, the bonding agent in the syringes 48 and 58 is discharged through the points of the nozzles 49 and 59. The arms 45 and 55 are rotated in the reverse direction to each other between the prescribed angles to the arms along with shafts 42 and 52, which are rotated by a motor 6, and make a motion symmetrical to each other.
