Description of the invention (1) ▲ This invention relates to the adjustment of the assembly of the motor, or the rotation axis of the motor, if it is installed in the spindle motor of a hard disk device. Method and device for correcting the rotation balance of the rotation unbalanced rotating body generated when the magnetic disk is installed. Fig. 8 is a perspective view of a more general structure in a conventional hard disk device. The disk core 321 rotated by the spindle motor is laminated with a plurality of magnetic disks 3 11 or at regular intervals. The magnetic head 319 is movably disposed on both sides or on one side of the magnetic disk 311. The magnetic head 319 is installed at the end of the rotary adjuster. The rotation adjuster 318 is provided with a coil 32o constituting a voice coil motor. When the spindle motor rotates, the magnetic head 319 floats slightly from the surface of the magnetic disk 311 through the air flow generated between the surface of the magnetic disk 311 and the magnetic head 319. The magnetic head 3 19 is rotated by the driving force of the voice coil motor with the rotation shaft 322 as the center ′ and moves on the magnetic disk 311 in the radial direction to read and write data. The floating amount of the magnetic head 319 is about several tens to several hundreds of faces. The entry of the dust from the head of the magnetic head 319 and the disk 是 is the cause of damage to the magnetic head 3 19 and the magnetic disk 3 11. For this reason, the hard disk device is assembled in a clean room and sealed with a cover 317 after assembly. Due to the influence of the dimensional error and assembly error of each component of this type of hard disk device, the center of gravity of the rotating center axis after assembly is not the same as that of the rotating part including the magnetic disk 3ΐ, resulting in unbalanced rotation. The disadvantages caused by this unbalanced rotation may reduce the readability of the magnetic head on the disk surface data track and increase the noise due to vibration. In addition, when the hard disk device is mounted inside the computer as an external memory device, it may cause damage to other computers. The device has an adverse effect. Figure 9 shows the conventional example of a gyration balance correction device for a rotating body.

If so, the disc center 306 can be rotated around the rotation axis 3 04 #, and the disc center 306 itself becomes the rotation axis of the spindle motor. An inner wall 3063 below the disc core 306 is embedded with an outer wall 3071 of a ring-shaped rear deflection coil 307, and an inner wall 3072 of the rear deflection coil 3007 is fixed with an outer wall 3081 of a ring-shaped rotating magnet 308. In addition, the base portion 301, the stator shaft center%] is fixed coaxially with the rotation shaft 304. The stator shaft center 302 faces the inner wall of the magnet 308 through an annular gap. The stator shaft center 300 is wound with a coil 300. By the current flowing through the coil 303, and the magnetic boundary action formed by the magnet 308, the deflection coil%? And the stator shaft 302, the motor obtains a turning force. In addition, without the deflection coil 307, a ring-shaped rotating magnet is directly fixed on the inner wall 3063 of the dish core 306, and the structure of the stone 3G8 is also widely used. In this case, the disc core 3G6 also has the function of a rear deflection coil, and it has the function of a spindle motor. The rotating body part of the motor is ideally composed of the center of gravity on the center axis of rotation, but in reality due to the dimensional error and assembly error of each component, the center axis of rotation may not be consistent with the center of gravity. . Next, a conventional method for correcting the rotational imbalance of the spindle motor will be described with reference to FIG. 9. f First, assemble the rotating part of the spindle motor.

Description of the invention (9) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The following details the weight plate 15 using Figures 2 and 3. As shown in these two figures, the weight plate 15 is a disc-shaped body having a coupling hole 156 that rotatably couples the rotary shaft 4 in the center. The weight plate 15 has a plurality of projections 丨 5 丨 formed radially at equal angular intervals on its outer periphery. The three mounting holes 157 are holes for fixing the disc core 6 by screws 14. The two rotation direction position determination holes 155 are formed at symmetrical positions with the holes 156 interposed therebetween. The weight plate 15 is made of a general metal material, and can be manufactured only by processing a plate, and can be mass-produced in a short time to reduce costs. Next, a method for correcting the swing balance will be described. After assembling the disk core 6, the disk π 'disk spacer 12, the platen disk 13 and the rotating body including the weight plate 15, the rotational unbalance of the rotating body is measured. According to the measurement result, one or more protrusions 151 on or in the vicinity of the semi-straight line connected to the unbalanced position by the center axis of rotation on the weight plate 15 are bent to the inside, and the center of gravity of the protrusions 151 is approached to the center of rotation. Swing balance correction. Regarding the positioning of the weight plate 15 in the plane direction during assembly, since the engaging hole 156 is inserted into the rotary shaft 4 and is mounted coaxially with the motor hard disk assembly, the distance from the rotary central shaft to any protrusion 丨 5 丨The error of the balance correction amount caused by the difference is a small amount that can be ignored, so the protrusions at any position are twisted 11.5, and the balance correction amount can be said to be constant. In addition, regarding the position positioning of the missing plate 15 in the turning direction, in FIG. 3, a line point 250 connecting two position positioning holes 155 is used as a reference line point, and the angle formed by the reference line point and each protruding portion is determined. It is 2000, so there is no need to worry about the errors, defects, and twists caused by the wrong selection of the protrusions that should be zigzag during the balance correction.

Description of the invention (10 Poor twists and turns caused by the displacement of the fixture The balance plate 15 can be correctly corrected. The weight plate 15 is an axisymmetric structure, and there is no imbalance in the design. The more the protruding portion 151 of the missing plate 15 is away from the rotation center axis, that is, the more it is on the outer peripheral side The greater the amount of balance correction, the greater the mass of the protrusion 151, the greater the amount of balance correction, and the greater the amount of possible balance correction. Conversely, the closer the protrusion 151 is to the center axis of the rotation, that is, the smaller the amount of balance correction on the inside, The smaller the mass of the protrusion 151 is, the smaller the balance correction amount is. The distance between the center of rotation of the protrusion ι5ΐ and the mass of the protrusion 15 丨 is determined by the optimum value of the maximum imbalance and the imbalance specification in the design and assembly method. Figures 4A and 4B show this section. The positional relationship between the large rise σρ 1 5 1 of the balance correction weight plate 15 and the magnetic head 19 in the embodiment. If the gap between the magnetic disk 11 and the protruding portion 15 1 is restricted in size in the height direction, it protrudes in the height direction. As long as the portion 151 interferes with the magnetic head 19, as shown by the arrow in FIG. 48, the protruding portion 151 shortens the front end 153 of the protruding portion so that it does not contact the magnetic head 19 so that it faces the center axis side of the rotation. As shown in the figure, the gap between the front end 153 of the protruding portion and the magnetic disk can be increased, and all the protruding portions ΐ5ΐ must be twisted upward by a certain amount. If so, the weight plate 15 is generated by design and assembly methods for the specific implementation. The position and mass of the protruding portion 151 set by the maximum imbalance amount and the unbalanced specification amount have a degree of freedom in designing the mounting structure.

In the rotation balance correction device of the first embodiment described above, if the zigzag positions of the protruding portions 151 are scattered, the correction amount is scattered, and a guaranteed balance correction amount cannot be obtained by design. However, when bending is usually performed, a clamp is added to determine the zigzag position. Λ In FIG. 5, the thickness of the root element 152 of the protrusion 151 is thinner than that of the front end μ), and the thickness of the root element 152 is the smallest in the protrusion 151, so that the bending rigidity of the root element 152 is the weakest. Therefore, without using a jig to increase the bending momentum at any position of the protruding portion 151, the meandering position of the root element 152 can be ensured, and a stable balance correction effect with less error can be obtained. In addition, the shape of the protrusion 151 is as shown on the right side of the rotation center axis in FIG. 5, and the thickness is reduced linearly from the front end of the protrusion 153 toward the root element 152, as shown on the left side of the rotation center axis in FIG. 5. The same effect can be obtained by forming the concave portion 15 4.
