Yes. Incidentally, each of the straight portion 11S and the curve portion 11C is configured by connecting the plurality of divided rails 10 described above.

  A plurality of the pallets 8 are provided so as to be slidable separately along the guide rails 11, and each pallet 8 is supported in a direction that always intersects the guide rails 11 (orthogonal direction in the illustrated example) and is viewed in plan view It extends to the outer side of the conveyance line L and is slidably engaged and supported on the guide rail 11 via the support 16.

  On the pallet 8, four L-shaped positioning members 15 into which the four corners of the workpiece W are fitted are installed so that the workpiece W having a square shape in plan view does not move, and various components 2 are positioned. You may provide the mounting part (not shown) to mount.

  A contact plate 17, which is a plate-shaped contact portion extending in the direction of the conveyance line L, is integrally extended downward from the base end portion that is the end portion on the support 16 side of the pallet 8. An opening 18 is formed at the center of the upper half of the abutting plate 17 in the conveyance line L direction. The opening 18 has a pair of vertical holding members 19 arranged in parallel in the conveyance line L direction. , 19 are provided.

  A plurality of the transport motors 13 are arranged in parallel along the annular transport line L at predetermined intervals in a state of being close to the guide rail 11. A single transport roller 12 is attached to the output shaft of each transport motor 13 so as to rotate integrally. The transport motor 13 rotates the transport roller 12 about its own axis.

  The conveyance motor 13 including the conveyance roller 12 is elastically pressed by an elastic member (not shown) so that the conveyance roller 12 is elastically pressed against the contact plate 17 of the pallet 8 slidably supported by the guide rail 11. It is supported in the vicinity of the guide rail 11 in a state where it is elastically biased toward the 11 side.

The engagement rod 22 is formed in a cylindrical shape extending in a direction intersecting with the divided rail 10 (orthogonal direction in the illustrated example), and is supported by the main body 21 so as to be movable back and forth in its own axial direction.

  The engagement rod 22 is moved forward and backward by driving means such as a solenoid, and the posture is switched between a retracted posture stored on the main body 21 side and an advanced posture protruding from the main body 21 toward the pallet 8 side by the forward / backward operation. . When the pallet 8 is transported to the vicinity of the positioning device 14 and the engagement rod 22 is switched from the retracted position to the advanced position, the engagement rod 22 is elastically held between the pair of holding bodies 14 of the opening 18. Then, while the pallet 8 is positioned at a predetermined position in the conveyance direction L, when the engagement rod 22 is switched from the advanced position to the retracted position in this positioning state, the positioning of the pallet 8 by the positioning device 14 is released.

  Further, when the pallet 8 is positioned on the transport line L by the positioning device 14, the positioning device 14 is moved along the split rail 10, so that the position adjustment of the pallet 8 on the transport line L is performed with high accuracy. It is possible.

  FIG. 3 is a plan view showing the configuration of the flow line control of the transport unit. The transport unit divides the transport line L into a plurality of points P and performs free flow line control. During this free flow line control, when a predetermined pallet 8 (target pallet 8) is positioned at a predetermined point P (target point P), work such as assembly work and receiving work described later at the target point P The first condition is that the above work at the target point P is not completed, and there is no other pallet other than the target pallet 8 at the next point P (next point P) of the target point P. When both the first condition and the second condition are satisfied as the second condition, the target pallet 8 is transported from the target point P to the next point P.

  Each of the points P is classified into a plurality of work points P that perform assembling work by the assembling unit 3 and a receiving work by the transfer unit 4 and non-work points P that do not perform such work. A plurality of the work points P are provided in each linear portion 11S of the guide rail 11, and a plurality of the non-work points P are provided in the curve portion 11C of the guide rail 11.

That is, the two straight portions 11S, one of the 11S, become assembling line _{L b,} the other will supply line _{L a.} Each work point P of the supply line L _a side, while installing the positioning device 14 and the transfer unit 4, each work point P of the assembly line L _b side, by installing the positioning device 14 and the assembling unit 3 Yes.

  Note that the positioning device 14 positions the pallet 8 at a position optimal for the operation of the assembly unit 3 or the transfer unit 4, thereby improving the efficiency of the operation. Incidentally, the free flow line control is highly versatile because it can be applied without changing the control contents even when the configuration of the transport line L is changed, such as changing the path length of the guide rail 11.

Next, the configuration of the hard disk drive D will be described with reference to FIGS.
4 to 6 are a divided side view, a plan view, and a bottom view showing the configuration of a hard disk drive that is a kind of magnetic disk device. The illustrated hard disk drive D includes a disk-shaped magnetic disk 23 having a storage surface 23a on both sides or one side, and a carriage that writes data to the storage surface 23a of the magnetic disk 23 or reads data from the storage surface 23a. 24 in a main body case 26 that is a rectangular plate-shaped housing that is open on one side, and the open side of the main body case 26 is closed by a case lid 27 while the case lid 27 of the main body case 26 is closed. A main board 28 is installed on the opposite surface.

  A plurality of the magnetic disks 23 are arranged at predetermined intervals so as to have the same axis, and are rotated by a single spindle motor (electric motor, actuator) 29 installed at the center of the plurality of magnetic disks 23. Is done.

  The carriage 24 includes a plurality of swing arms 32 that are oscillated in the radial direction of the magnetic disk 23 along the storage surface 23a of the magnetic disk 23 via bearings 31 that are disposed near the outer periphery of the magnetic disk 3; A fan-shaped spacer 33 extending in the opposite side of the swing arm 32 across the bearing 31 with a fan shape centering on the bearing 31 axis serving as a swing fulcrum of the swing arm 32, and the bearing 31 side of the swing arm 32 ( And a single plate-like base portion 34 installed on the base end side).

  The swing arm 32 includes a plate-like arm main body 36 protruding from the base end side to the front end side, and a plate-like suspension 37 protruding further from the arm main body 36 to the front end side. The suspension 37 is attached and fixed in a state where the base end side half of the suspension 37 is superimposed on the side. The swing arms 32 are formed in a plate shape parallel to the storage surface 23a of the magnetic disk 23 as a whole, and are provided as many as the storage surfaces 23a (four in the illustrated example). Are rocked integrally in the same posture.

  Each of the suspensions 37 is configured to be elastically deformable in a direction away from and close to the storage surface 23a of the magnetic disk 23, and on the side of the surface of the suspension 37 opposite to the storage surface 23a, the magnetic disk A magnetic head (head) 38 for reading data from and writing data to the storage surface 23a is provided.

  A part of the fan-shaped spacer 33 is inserted between the drive unit 39 installed along the bottom surface of the main body case 26 and the bottom surface, and is configured to swing integrally with the swing arm 32. The carriage 24 is placed on the storage surface 23 a of the magnetic disk 23 by a voice coil motor which is a swing actuator comprising a magnet (not shown) on the drive unit 39 side and a voice coil (not shown) provided on the sector spacer 33. And is driven to swing along the radial direction.

  Then, the head 38 is moved to the storage surface 23a side by the swing drive of the swing arm 32 by the voice coil motor, and the data is stored and reproduced, and the head 38 is moved to the magnetic disk by the swing drive of the swing arm 32. 23, when the reading of data from the storage surface 23a and the writing to the storage surface 23a are stopped, the head 38 is attached to the ramp mechanism 41 installed along the peripheral portion of the magnetic disk 23. It is locked stably. Incidentally, the swing arm 32 locked to the ramp mechanism 41 is arranged and configured to retract to a position where it does not overlap with the magnetic disk 23 in plan view. The lamp mechanism 41 is held in a locked state.

  The head 16 and the boil coil motor are electrically connected to the base 34 side via a connection circuit (not shown) along the carriage 4, and the base 32 is electrically connected to the relay board 43 via the flexible board 42. Connected to. The relay board 43 is connected to the main board 28 via the relay connector 44, and the main board 28 controls the swing of the carriage 24 and the data storage / reproduction by the head 38.

  By the way, while reading or writing data, the magnetic disk 23 is rotationally driven at a predetermined speed in the normal rotation direction (counterclockwise in FIG. 5), and the head 38 is separated from the storage surface 23a by a minute distance (floating). In this state, if particles, which are minute dust, bite between the storage surface 23a and the head 38, there is a possibility that a problem occurs in reading or writing data.

  For this reason, it is necessary to remove particles from the inside of the main body case 26 (particularly the storage surface 23a) closed by the case lid 27. For this reason, the main body case 26 is provided with a capturing means 46 for capturing particles. On the other hand, this magnetic disk apparatus assembly machine prevents particles from adhering to the magnetic disk 23 during assembly work and removes particles adhering to the magnetic disk (mainly to the particle storage surface 23a). Purge means, which is an exclusion means for eliminating particles) is provided.

Next, the configuration of the capturing means 46 will be described with reference to FIG.
The capturing means 46 includes an introduction path 48 that extends from the peripheral side of the magnetic disk 23 toward the tangential forward rotation side, a lead-out path 49 that bypasses the introduction path 48 and returns to the peripheral side of the magnetic disk 23, and the lead-out path 49. It is comprised from the acquisition filter 51 installed.

  At the time of data storage and reproduction in which the magnetic disk 23 is driven to rotate in the forward direction, the wind generated by the rotation of the magnetic disk 23 flows from the introduction path 48 to the lead-out path 49, passes through the capture filter 51, and is again magnetic Although returned to the disk 23 side, the particles transferred by the wind are captured in the process of passing through the capture filter 51. Incidentally, when the main body case 26 is sealed with the case lid 27, the capturing effect of the capturing means 46 is particularly enhanced.

Next, the configuration of the purge means of the present invention will be described with reference to FIGS.
The purge means includes the spindle motor 29 described above and a power supply device (drive control means) 52 that directly supplies power to the spindle motor 29 to drive the spindle motor 29.

Workpiece W described above, at the time supplied from the supply line L _a, is assembled to the state spindle motor 29 is assembled to the main body case 26. The workpiece W is provided with a supply portion 53 for supplying electric power to the spindle motor 29 at a portion where the spindle motor 29 is located on the central portion side of the main substrate 28 side surface (back surface) of the main body case 26. A supply terminal 54 that is electrically connected to the supply unit 53 via a connection circuit 56 is formed at the end on the long side of the back surface.

  The supply terminal 54 is connected to the main board 28 and enables the rotational drive of the spindle motor 29 to be controlled from the main board 28 side. In the assembly work by the magnetic disk apparatus assembly machine, the main body case 26 of the work W is provided. After the necessary parts 2 such as the carriage 24 described above are assembled therein, the assembly operation is performed until the open side of the main body case 26 is closed in a sealed state by the case lid 27. The work of assembling 28 is not performed. That is, during the work by the magnetic disk device assembly machine, the main substrate 28 is not assembled to the workpiece W, and the supply unit 53 and the supply end 54 are always exposed.

  The power supply device 52 described above includes a power source (not shown), and a connection terminal (terminal portion) 57 connected to either the supply portion 53 or the supply terminal 54 so as to be able to be disconnected / connected (connectable). ing. The connection terminal 57 includes a detachable connector, a plurality of probe pins 57a (probe pins in the illustrated example), and the like, and is electrically connected to a power source. The connection terminal 57 is connected to either the supply unit 53 or the supply terminal 54 to supply power from the power source to the spindle motor 29, while being disconnected from either the supply unit 53 or the supply terminal 54. As a result, the power supply from the power source to the spindle motor 29 is stopped.

  As described above, when electric power is supplied from the power supply device 52 to the spindle motor 29, the magnetic disk 23 is rotationally driven, and particles adhering to the storage surface 23a are blown off and removed. Particles are prevented from adhering to the storage surface 23a, and the particles are excluded from the workpiece W. Incidentally, during the rotational drive of the magnetic disk 23, an exclusion wind is generated toward the radially outer side on the storage surface 23a, and the attachment of particles to the storage surface 23a is effectively prevented by the exclusion wind. When the main body case 26 is closed by the case lid 27, the capturing of particles by the capturing means 46 described above is promoted.

  That is, the assembly work of the component 2 in the main body case 26 is a process in which particles are most likely to adhere during the manufacturing process of the hard disk drive D. During this process, the magnetic disk 23 is driven to rotate. Therefore, the above-described exclusion wind is generated, and the adhesion of particles to the storage surface 23a is efficiently prevented.

  A plurality of connection terminals 57 are arranged along the transfer line L. When the work W is transferred along the transfer line L and various operations are performed, the magnetic disk 23 is connected to the connection terminals 57. It is driven to rotate intermittently by the interruption.

  More specifically, the connection terminal 57 is installed at each of the plurality of work points P described above or in the vicinity thereof, and also installed at a predetermined non-work point P or in the vicinity thereof as necessary. Has been. On the other hand, on the pallet 8, a workpiece W composed of the main body case 26 and the like with the back side facing downward is positioned and placed. At this time, the supply portion 53 and the supply end portion 54 of the workpiece W are provided. An exposure window 8 a is formed in the center of the pallet 8 so as to be exposed from the lower side of the pallet 8.

  Then, at a plurality of predetermined points P (especially during the work at the work point P for performing assembly work, receiving work, etc.), the work W supply section 53 or the supply of the work W on the pallet 8 through the exposure window 8a A connection terminal 57 that moves up and down by an electric cylinder or the like is connected to the end portion 54 so as to be connectable and disconnectable, and the magnetic disk 23 of the workpiece W is rotationally driven. In addition, while the pallet 8 on which the workpiece W is placed is traveling between the plurality of predetermined points P, the magnetic disk 23 is rotated by inertia. In other words, while the magnetic disk 23 is being intermittently driven while being transported along the transport line L, the magnetic disk 23 can be maintained in a rotating state.

  Incidentally, when the various parts 2 are assembled in the main body case 26 and the work W is assembled by the magnetic disk device assembly machine until the open side of the main body case 26 is closed by the case lid 27, subsequent manufacturing operations are performed. During repair work, the possibility of particles being mixed inside is greatly reduced, and even if particles are mixed, particles can be efficiently removed by using the capturing means 46.

  In addition, while the conveyance line L is being conveyed, a current collector having substantially the same configuration as that used for a train may be used so that power can be constantly supplied to the spindle motor 29 of the workpiece W. The plurality of connection terminals 57 and the above flow line control greatly simplify the structure of the device and the control structure compared to the case where a current collector is used.
