At this time, two bases (B) on which the spindle motor (M) is fixed are arranged on the upper part of the pallet (40), and the spacer (S) and the clamp (C) are held in a supported state (FIG. 4). . In addition, a sufficient number of hard disks should be stacked in the disk case 78. The pallet 40 is stopped by the stopper 51.

Then, the disk support column 61 enters below the lowermost disk of the stacked hard disks D through the space formed under the disk case 78. When the column 61 enters the disk D stacked on the disk case 78, the drive motor 57 prevents the column 61 and the disk D from interfering with each other. The height is adjusted.

When the column 61 enters and stops below the lowermost disc D, the case support 63 is lowered at predetermined intervals. The lowering of the case support 63 continues until the lowermost disk D is supported on the upper surface of the column 61, and once the disk D is detected to be supported on the upper surface of the column 61, the case support The descent of 63 stops.

The column 61 then moves to a position close to the conveyor by driving the cylinder 60 and stops within the operating range of the suction head 53. When the stop of the column 61 is confirmed, the suction head moves to the position indicated by the reference numeral 53 'by the movement of the robot 52. The suction head sucks the hard disk D using a vacuum and places it in the spindle motor M hub of the base B supported by the pallet 40. At this time, the fine horizontal error caused when the hub of the spindle motor H and the hollow of the hard disk D do not coincide with each other due to the action of the ball 68 and the ball plunger 70 installed on the head support 69. The impact force in the horizontal direction due to the rapid movement and stop of the robot 52 can be completed by the spring 71 (FIG. 6).

Once the first disk is fitted to the hub of the motor, the process of fitting the spacers (S) must then be carried out. The adsorption head 53 moves to the upper part of the spacer S supported by the support part of the pallet 40, and adsorb | sucks the spacer S. FIG. The spacer S adsorbed by the adsorption part 65 is fitted to the hub of the spindle motor.

The above process is continued until a predetermined number of spacers and hard disks are stacked on each spindle motor hub. (In the embodiment shown in the figure, it continues until two spacers S and three and the hard disk D are stacked). In the above process, when the hard disk supported on the upper part of the four support columns 61 connected by the connecting bar 82 is exhausted, the column 61 enters the lowermost disk supported by the hard disk case 78 again. To move the disk D to the suction position. As the disk D supported by the case 78 runs out, the case support part 63 moves downward.

When both the spacer and the hard disk are disposed in the spindle motor hub, the stopper 81 is released, and the pallet 40 is transferred to the next clamping step.

The hard disk driver assembly apparatus according to the present invention is very effective because it is possible to accurately and quickly perform the assembly of the hard disk and the spacer to the spindle motor hub of the hard disk driver.
