Description

  The present invention relates to a recording disk drive fixture, a recording disk drive manufacturing method, and a recording disk drive test apparatus.

  As data storage devices, devices using various types of media such as optical disks and magnetic tapes are known. Among them, a hard disk drive (HDD) is widely used as a computer storage device, and is one of the storage devices indispensable in the current computer system. Furthermore, not only computer systems, but also the use of HDDs, such as moving image recording / playback devices, car navigation systems, mobile phones, and removable memories used in digital cameras, are increasingly expanding due to their superior characteristics. .

  The HDD includes a magnetic disk for storing data and a head slider for accessing the magnetic disk. The head slider has a head element portion that reads and / or writes data from and to the magnetic disk, and a slider on which the head element portion is formed. The HDD further includes an actuator that moves the head slider to a desired position on the magnetic disk. The actuator is driven by a voice coil motor (VCM), and rotates about the rotation axis to move the head slider in the radial direction on the rotating magnetic disk. As a result, the head element section can access a desired track formed on the magnetic disk and perform data read / write processing.

  After assembling the components, the HDD is connected to an external test apparatus to perform operation tests and various parameter settings and adjustments. In an HDD related to mass production, a large number of HDDs are connected to a test apparatus at a time, and the operation test and the like are performed. The test apparatus includes a chamber in which the HDD is accommodated and the temperature inside can be adjusted, a fixture that fixes the HDD inside the chamber, a test computer that causes the HDD to perform a test, and a connector that connects the computer to the HDD. The HDD is inserted into the chamber of the test apparatus and connected to the connector.

As described above, since the magnetic disk rotates at a high speed inside the HDD in operation and the actuator repeatedly rotates, vibration is generated in the housing that forms the outside of the HDD. When the HDD housing vibrates, the performance of positioning the head on a predetermined track during the test operation deteriorates, and an unnecessary error occurs, making it impossible to perform an appropriate test. Further, since a large amount of HDD is stored in the chamber, it is necessary to prevent the influence of vibration of other HDDs. As a method for fixing the HDD, Patent Document 1 discloses a mounting member for a magnetic disk device that can absorb variations in the standard allowable range in the width direction of the magnetic disk device. Patent Document 2 discloses a mounting structure for a magnetic disk device that suppresses vibration of the magnetic disk device and guarantees the operation of the magnetic disk device that rotates at high speed.

  When the HDD is fixed with screws as shown in Patent Document 1, it takes a very long time to attach and detach the HDD to and from the test apparatus, and the time required for the HDD test becomes long. As a result, HDD productivity decreases. Further, when the HDD is pressed and fixed as shown in Patent Document 2, it is necessary to optimally set the pressing load according to the type of the HDD. For example, if the force pressing the HDD is too strong, the HDD may be deformed. Further, if the force to press the HDD is strong, the vibration of the housing can be suppressed correspondingly. Therefore, it is conceivable that the HDD that cannot pass the test under the actual use conditions passes the test. On the other hand, if the force pressing the HDD is too weak, the vibration of the housing cannot be suppressed and the test cannot be performed properly.

  Furthermore, if the resonance frequency of the member that holds down the HDD matches the resonance frequency of the HDD, the vibration is not attenuated at all, and the test cannot be performed properly. Also, HDDs have various shapes even when they are the same size. Therefore, in order to reduce the test cost of the HDD, a general-purpose fixture that can handle any shape of HDD is preferable. However, the design becomes difficult unless the shape of the HDD is specified to some extent. It should be noted that not only the HDD test apparatus but also the mounting / demounting of the HDD is troublesome even in actual use, and a simple mounting / demounting mechanism for the HDD is desired.

  The present invention has been made in the background of such circumstances, and one of its purposes is to reduce the time required for testing the recording disk drive and to improve the productivity of the recording disk drive. It is. Another object of the present invention is to provide a recording disk drive fixture capable of easily attaching and detaching the recording disk drive.

In conjunction with this, it is preferable that the fixing release part releases the fixation of the adapter by the adapter fixing part. Thereby, replacement | exchange of an adapter can be performed easily.

  Further, it is preferable that the movement of the operation unit for releasing the fixing of the adapter requires a larger force than the movement for ejecting the recording disk drive. Thereby, it is possible to prevent the adapter from being detached in a normal operation.

  The fixing mechanism further includes an elastic body that prevents movement of the fixing release portion when the operation portion is moved beyond the normal range, and the fixing release portion crushes the elastic body. It is preferable to release the adapter fixing portion fixing by moving.

  In addition, the fixing mechanism further includes a guide rail that supports a bottom surface of the recording disk drive in a state where the recording disk drive is fixed to the housing fixing part, and the operation unit includes the recording disk drive in the fixing mechanism. It is preferable that the surface that supports the bottom surface of the guide rail and the surface of the operation portion are substantially flush with each other in a state where the operation portion is disposed on the insertion side and the operation portion is pushed into the base. . This prevents the recording disk drive from colliding with the end of the guide rail and being damaged when the recording disk drive is inserted into the fixture.

In addition, in each drawing, the same code | symbol is attached | subjected to the same element and the duplication description is abbreviate | omitted as needed for clarification of description. The present embodiment relates to a manufacturing process of a hard disk drive (HDD), and particularly to a test process after assembly. In the HDD test process of this embodiment, the HDD is fixed to a fixture provided in a dedicated test apparatus, and the HDD is tested. This mechanism of the fixture is one of the features of this embodiment.

  First, the overall configuration of the HDD will be described. FIG. 1 is a plan view schematically showing the configuration of HDD 100 according to the present embodiment. The HDD 100 includes a magnetic disk 101 as a recording disk for recording data. The magnetic disk 101 is a non-volatile memory that records data by magnetizing a magnetic layer. Each component of the HDD 100 is accommodated in the base 102. The base 102 constitutes a disk enclosure (housing) by being fixed via a cover (not shown) and a gasket (not shown) that close the upper opening of the base 102, and can accommodate each component of the HDD 100. it can.

The actuator 106 includes constituent members coupled in the order of the suspension 110, the arm 111, the coil support 112, and the flat coil 113 from the tip in the longitudinal direction where the head slider 105 is disposed. The VCM 109 includes a flat coil 113, a stator magnet (not shown) fixed to the upper stator magnet holding plate 114, and a lower stator magnet (not shown).

  The magnetic disk 101 is integrally held by a spindle motor (SPM) 103 fixed to the base 102 and is rotated at a predetermined angular velocity by the SPM 103. In order to read / write data from / to the magnetic disk 101, the actuator 106 moves the head slider 105 over the data area on the surface of the rotating magnetic disk 101. The pressure due to the viscosity of air between the ABS (Air Bearing Surface) surface of the slider facing the magnetic disk 101 and the rotating magnetic disk 101 balances with the pressure applied to the magnetic disk 101 by the suspension 110. The head slider 105 floats on the magnetic disk 101 with a certain gap. When the rotation of the magnetic disk 101 stops, the actuator 106 retracts the head slider 105 from the data area to the ramp mechanism 115.

In the present embodiment, 120 HDD insertion portions 201 are provided for one test apparatus 200. The HDD 100 inserted in each HDD insertion unit 201 is connected to the test computer 202. A test program, command, parameter information, and the like are transmitted from the test computer 202 to the HDD 100 inserted in each HDD insertion unit 201. The HDD 100 that has received the above information and command from the test computer 202 executes a test based on the received information.

  The HDD insertion unit 201 will be described in detail with reference to FIG. FIG. 3 is a perspective view showing the HDD insertion portion 201. As shown in the figure, the HDD insertion unit 201 includes a cell 211, a connection substrate 212, and an HDD fixture 300. A cell 211 is a room into which the HDD 100 to be inspected is inserted. The connection board 212 is an adapter having connectors corresponding to the interface connector and power connector of the HDD 100 to be inspected, and is connected to the HDD 100 to be inspected in the cell 211. Further, the connection board 212 is connected to the test computer 202, whereby the HDD 100 and the test computer 202 are connected, and communication between the HDD 100 and the test computer 202 and power supply to the HDD 100 can be performed. .

Specifically, the interface connector and power connector of the HDD 100 and the connectors formed on the connection board 212 are arranged to face each other in the direction in which the HDD 100 is inserted into the HDD fixture 300.

  When the HDD 100 is fixed to the HDD fixing device 300, the HDD fixing device 300 is opened, the surface A on which the interface connector of the HDD 100 is formed faces the connector of the connection board 212, and the insertion end 310 of the HDD fixing device 300 is placed. The HDD 100 is inserted into the HDD fixture 300 from the side. At this time, the HDD 100 is slid in a direction perpendicular to the surface A, the HDD 100 is pushed in until the interface connector of the HDD 100 and the connector of the connection board 212 are connected, and the HDD 100 and the connection board 212 are connected. When the HDD 100 and the connection board 212 are connected, the HDD 100 is held by the HDD fixture 300 by operating the HDD fixture 300 and switching to the holding state. In this way, by completely switching the HDD fixture 300 after the HDD 100 and the connection board 212 are completely connected, incomplete connection between the HDD 100 and the connection board 212 can be avoided.

  Next, the HDD fixture 300 will be further described with reference to FIGS. 3, 4, and 5. FIG. 4 is a top view showing the HDD fixture 300 in the opened state. FIG. 5 is a top view showing the HDD fixture 300 in the holding state. 4 and 5, the HDD 100 and the connection board 212 held by the HDD fixing device 300 are shown as being transparent by broken lines.

The base plate 301 is fixed to the inner wall of the cell 211, and the HDD fixture 300 is fixed inside the cell 211.

  In the state where the HDD fixing device 300 holds the HDD 100, the base plate 301 is bent at the ends corresponding to both side surfaces of the HDD 100 vertically, and these end portions form a side surface 301a. The side surfaces 301 a on both sides are positioned substantially parallel to the opposite side surfaces of the HDD 100 held by the HDD fixture 300. The guide rail 302 is provided inside the HDD fixture 300 and on the side surface 301a. The guide rail 302 serves as a guide for the HDD 100 when the HDD 100 is inserted into the HDD fixture 300. That is, both side ends of the bottom surface of the HDD 100 slide on the guide rail 302. When the HDD 100 is fixed, the bottom surface of the HDD 100 is supported by the guide rail 302. Further, the guide rail 302 also plays a role of pressing the HDD 100 with the leaf spring 305 in the holding of the HDD 100. Further, the guide rail 302 also functions to fix the connection board 212 in conjunction with the board fixing bracket 308. Details of these will be described later.

  The operation plate 303 is a lever for switching between fixing and releasing the HDD 100. The operation plate 303 is a plate-like member. As shown in FIGS. 4 and 5, the operation plate 303 is movable relative to the base plate 301, and the direction thereof is a direction in which the HDD 100 is inserted into the HDD fixture 300. The operation plate 303 has an operation portion 303 c at the end corresponding to the insertion end 310 of the HDD fixture 300. The operator operates the operation plate 303 by pushing or pulling the operation unit 303c. The link mechanism 304 is a member in which a link plate 304a and a link plate 304b which are bent in a square shape are overlapped and are pivotally connected by a rotation shaft 304c at the center thereof. The link mechanism 304 is also connected to the base plate 301 by a rotating shaft 304c. Therefore, the link plate 304a and the link plate 304b are rotatable with respect to the base plate 301 about the rotation shaft 304c.

  The operation plate 303 and the link mechanism 304 are connected to each other at the end of the operation plate 303 opposite to the operation unit 303c. Specifically, the link plate 304a is rotatably connected to the operation plate 303 by a rotation shaft 304d, and the link plate 304b is rotatable to the operation plate 303 by a rotation shaft 304f. It is connected. Thus, the link mechanism 304 is operated by moving the operation plate 303 relative to the base plate 301. The link plates 304 a and 304 b are connected to a slide hole 303 a that is an elliptical through hole formed in the operation plate 303. Thereby, the rotation shaft 304d and the rotation shaft 304f can slide inside the slide hole 303a.

  Link mechanism 304 is also coupled to ejector 307. The ejector 307 operates in conjunction with operation of the operation plate 303 to remove the HDD 100 from the connector of the connection board 212. The ejector 307 includes a contact portion 307 a that pushes the HDD 100 during ejection and a connecting portion 307 b that is connected to the link mechanism 304. The contact part 307 a and the connection part 307 b are integrally formed and move integrally along the guide rail 302. The contact portion 307 a contacts the surface A of the HDD 100. The link plates 304 a and 304 b are connected to the connecting portion 307 b at the end opposite to the end connected to the operation plate 303.

  The ejectors 307 are respectively connected to the guide rails 302 on both sides of the base plate 301, and are provided symmetrically. One of the ejectors 307 is connected to the link plate 304a, and the other is connected to the link plate 304b. Specifically, the link plate 304a is connected to the connecting portion 307b at its end by a rotating shaft 304g, and the link plate 304b is connected to the connecting portion 307b at its end by a rotating shaft 304e. . A slide hole 307c is formed in the connecting portion 307b similarly to the operation plate 303, and the rotation shaft 304g and the rotation shaft 304e can slide inside the slide hole 307c.

  The operation plate 303, the link mechanism 304, and the ejector 307 move in conjunction with each other. In the open state of the HDD fixture 300 shown in FIG. 4, the link mechanism 304 is in a closed state, and the operation plate 303 and the ejector 307 are close to each other. That is, the rotation shaft 304d and the rotation shaft 304e, and the rotation shaft 304f and the rotation shaft 304g are close to each other. In other words, the operation plate 303 and the ejector 307 are in a state closest to the rotation shaft 304c. In the holding state of the HDD fixing device 300 shown in FIG. 5, the link plates 304a and 304b of the link mechanism 304 rotate, and the rotation shaft 304d and the rotation shaft 304e, and the rotation shaft 304f and the rotation shaft 304g are mutually connected. Opened. The operation plate 303 is moved to the insertion end 310 side, and the ejector 307 is moved to the opposite side.

  That is, when the operation plate 303 is moved in a direction away from the connection substrate 212, the ejector 307 is moved in a direction away from the operation plate 303 via the link mechanism 304. Further, when the operation plate 303 is moved in a direction approaching the connection substrate 212, the ejector 307 is moved in a direction approaching the operation plate 404 via the link mechanism 304. Details of the interlocking operation of the operation plate 303, the link mechanism 304, and the ejector 307 will be described later.

  The leaf spring 305 is an elastic plate-like member that generates a pressing force for the HDD fixture 300 to hold the HDD 100. The plate spring 305 is fixed to one side surface 301 a so that the plate surface is parallel to the side surface 301 a of the base plate 301. A pressing member 306 is attached to the leaf spring 305. The pressing member 306 is attached to one end and the other end of the leaf spring 305, respectively. The size of the leaf spring 305 corresponds to the interval between screw holes provided on the side surface of the HDD 100. The pressing member 306 is aligned with the position of a screw hole formed on the side surface of the HDD 100 in a state where the HDD fixing tool 300 holds the HDD 100. Since the screw hole on the side surface of the HDD is defined in the standard, any HDD can be supported by adopting a configuration in which the periphery of the screw hole is pressed. The pressing member 306 is an elastic body and is formed of a synthetic rubber, a plastic material, or the like. The leaf spring 305 generates a pressing force, and the pressing member 306 contacts the HDD 100 to press the HDD 100. By changing the size, hardness, and the like of the pressing member 306, the load that presses the HDD 100 can be changed. That is, by replacing the pressing member 306, the load with which the HDD fixture 300 presses the HDD 100 can be changed.

  The leaf spring 305 is interlocked with the operation of the operation plate 303. Operations of the leaf spring 305 and the operation plate 303 will be described with reference to FIGS. 6 (a), (b), and (c). FIG. 6A is a side view of a part of the side surface of the HDD fixture 300 on the side where the leaf spring 305 is formed as viewed from the outside in the state of FIG. In FIG. 6A, the side surface 301a is omitted for ease of explanation. 6B is a top view showing a part of the leaf spring 305 and its periphery in the state of FIG. 5, and FIG. 6C shows a part of the leaf spring 305 and its periphery in the state of FIG.

Therefore, in the state of FIG. 6B, the distance between the pressing surface of the pressing member 306 and the surface of the guide rail 302 opposite to the pressing surface is the size of the HDD 100 held by the HDD fixture 300 and the target pressing force. It is determined corresponding to. The HDD fixture 300 of the present embodiment is intended for a 3.5-inch HDD, and the distance between the pressing surface of the pressing member 306 and the surface of the guide rail 302 facing the state shown in FIG. 5 is about 10 cm.

The spring end 305a abuts on the operation plate 303, and the spring end 305a is pushed from the operation plate 303, whereby the leaf spring 305 is bent. The spring end portion 305a protrudes in a direction perpendicular to the longitudinal direction of the leaf spring 305, and the protruding end is further bent in a key shape. As shown in FIGS. 6B and 6C, the end of the spring end 305a is bent with respect to the plate surface of the plate spring 305 main body, and is inclined with respect to the plate surface.

  The operation plate 303 has a spring pressing portion 303b. The spring pressing portion 303b is an end portion in a direction perpendicular to the moving direction of the operation plate 303 with respect to the base plate 301, and is formed on the side where the leaf spring 305 is disposed. The spring pressing portion 303b contacts the spring end 305a of the plate spring 305 and bends the plate spring 305 by pushing the spring end 305a. As shown in FIG. 6 (b), the spring pressing portion 303 b protrudes in the direction parallel to the plate surface at the end of the operation plate 303, and the operation plate 303 moves relative to the base plate 301. And has an inclined surface.

  As shown in FIG. 6A, in the direction perpendicular to the plate surface of the base plate 301, the plate spring 305 has a main body positioned higher than the operation plate 303, and the spring end 305a and the operation plate 303 are separated from each other. Arranged to overlap. Further, as shown in FIGS. 6B and 6C, the operation plate 303 moves in a direction approaching the connection substrate 212, so that the spring end portion 305a and the spring pressing portion 303b come into contact with each other. Is placed. In the state of FIG. 6C, the leaf spring 305 is bent so that the pressing member 306 is separated from the HDD 100 by the spring pressing portion 303 b pressing the spring end portion 305 a. Thus, the leaf spring 305 is switched between the standard state and the curved state when the operation plate 303 moves relative to the base plate 301. In the state shown in FIG. 6B, the inclined tip end of the spring end 305a and the slope of the spring pressing portion 303b are arranged to face each other.

  FIG. 7 is a cross-sectional view taken along the cutting line BB in FIG. As shown in FIG. 7, the pressing member 306 is fixed by being pushed into a through hole formed in the leaf spring 305. The pressing member 306 has a plurality of convex portions 306 a on the pressing surface that presses the HDD 100. The convex portion 306a has an upward slope 306b. By pressing the convex portion 306 a against the HDD 100, the convex portion 306 a is deformed and applies a downward force to the pressed surface of the HDD 100. Therefore, the pressing member 306 applies a pressing force in a direction perpendicular to the pressed surface of the HDD 100 and presses the HDD 100 downward. As a result, the HDD 100 can be held more securely.

  The board fixing metal fitting 308 will be described with reference to FIGS. 8A and 9A. 8A is a top view showing the board fixing bracket 308 and its surroundings in the state of FIG. 4, and FIG. 9A is a board fixing fitting 308 and its surroundings in the same state as FIG. 8A. FIG. In FIG. 8, the connection substrate 212 is shown by being transmitted through a broken line. The board fixing metal fittings 308 are respectively provided on the guide rails 302 on both sides, and are fitted into the recesses 212a formed on the connection board 212 to fix the connection board 212. The board fixing bracket 308 is connected to the guide rail 302 so as to be relatively movable. The guide rail 302 in the vicinity of the part is provided with a groove 302a for supporting the connection substrate 212. The connection board 212 is supported by being inserted into the guide rail 302 by sliding the groove 302a at both ends. The board fixing metal fitting 308 is disposed so as to cross the groove 302a. As a result, the connection substrate 212 is fixed in a state where it is supported by the substrate fixing bracket 308 in the groove 302a. The operation of the board fixing bracket 308 is interlocked with the operation of the ejector 307.

  The interlocking of the operation of the ejector 307 and the board fixing bracket 308 will be described with reference to FIGS. 8B and 8C and FIGS. 9B and 9C. This operation enables the connection substrate 212 to be unfixed by the substrate fixing bracket 308 by operating the operation plate 303. FIG. 8B is a top view showing the board fixing bracket 308 and its periphery in the state of FIG. 5, and FIG. 9B is the board fixing bracket 308 and its periphery in the same state as FIG. 7B. FIG. FIG. 8C shows a state in which the operation plate 303 is further away from the connection substrate 212 from the state of FIG. 8B, and FIG. 9C similarly shows further operation from the state of FIG. 9B. In this state, the plate 303 is away from the connection substrate 212.

  As shown in FIG. 9B, the elastic body 309 is arranged on the movement locus of the ejector 307 so as to face the ejector 307 from the side opposite to the insertion end 310. The elastic body 309 is fixed to the guide rail 302 and is disposed at a position facing the connecting portion 307b. In the state of FIG. 5, the connecting portion 307 b is in contact with the elastic body 309, thereby restricting the operation. The board fixing bracket 308 is also disposed on the movement locus of the ejector 307. A slope 307 d is formed in the portion of the ejector 307 facing the board fixing bracket 308.

  In this state, when the operation plate 303 is further moved away from the connection substrate 212, the ejector 307 moves while crushing the elastic body 309, and the state shown in FIGS. 8B and 9C is reached. That is, the inclined surface 307d and the substrate fixing metal fitting 308 come into contact with each other, and the substrate fixing metal fitting 308 is pushed up along the inclined surface 307d. As a result, the board fixing bracket 308 is detached from the recess 212a of the connection board 212, and the connection board 212 can slide in the groove 302a. In the normal operation of the operation plate 303, the movement of the operation plate 303 is restricted by the elastic body 309, and the board fixing bracket 308 is not pushed up by the ejector 307 as shown in FIG. 9B. However, when the operation plate 303 is pulled strongly, the elastic body 309 is crushed as shown in FIG. 9C, and the board fixing bracket 308 is pushed up by the ejector 307. Accordingly, by strongly pulling the operation plate 303 in a state where the HDD 100 is not fixed to the HDD fixing device 300, the connection substrate 212 can be released and the connection substrate 212 can be easily replaced. In operation, the connection board 212 can be prevented from being released.

  Next, operations of the operation plate 303, the link mechanism 304, and the ejector 307 will be described with reference to FIGS. 4, 5, 10, and 11A to 11C. FIG. 10 is a top view showing the HDD fixture 300 in the state between FIG. 4 and FIG. FIGS. 11A to 11C are top views showing the link mechanism 304 and its surroundings in the states of FIGS. 4, 10, and 5, respectively. In FIG. 10 and FIG. 11, the connection board 212 and the HDD 100 are shown as transparent by broken lines. As shown in FIG. 4, the operator holds the HDD 100 and pushes the HDD 100 into the HDD fixture 300 while the operation unit 303 c is pushed all the way down. Then, as shown in FIG. 4, the HDD 100 comes into contact with the contact portion 307 a of the ejector 307. The HDD 100 is further moved from this state, and as shown in FIG. 10, the HDD 100 abuts on the connection board 212, and the interface connector of the HDD 100 is connected to the connector of the connection board 212 and pushed in until it can no longer move.

  While the HDD 100 is pushed from the state of FIG. 4 to the state of FIG. 10, the HDD 100 pushes the contact portion 307a. The contact portion 307 a is pushed by the HDD 100 and moves relative to the base plate 301 along the guide rail 302. At the same time as the contact portion 307a, the connecting portion 307b also moves. When the connecting portion 307b moves, the link mechanism 304 connected thereto moves. Hereinafter, the movement of the link mechanism 304 will be described with reference to FIG. Since the link plate 304a and the link plate 304b move symmetrically, only the link plate 304b will be described in the following description.

  When the connecting portion 307b moves, the rotation shaft 304e moves accordingly. As shown in FIG. 11A, the rotation shaft 304e rotates on a plate surface parallel to the plate surface of the base plate 301 around the rotation shaft 304c along the locus of the arrow P in the drawing. At this time, as shown in FIG. 11B, the rotation shaft 304e slides inside the slide hole 307c, thereby absorbing the difference between the rotation locus of the rotation shaft 304e and the movement locus of the connecting portion 307b. . As a result, the link plate 304b rotates. Accordingly, the rotation shaft 304f rotates about the rotation shaft 304c while drawing the locus of the arrow Q in the drawing. As the rotation shaft 304f rotates, the operation plate 303 connected to the rotation shaft 304f moves. The operation plate 303 moves along the guide rail 302. At this time, as shown in FIG. 11B, the rotation shaft 304f slides inside the slide hole 303a, so that the difference between the rotation locus of the rotation shaft 304f and the movement locus of the operation plate 303 is absorbed. Such an operation leads to the state shown in FIG. 10 from the state shown in FIG.

  In the state shown in FIG. 10, the leaf spring 305 is in the state shown in FIG. 6C, and the HDD fixture 300 is not yet held. In this state, when the operator pulls the operation plate 303, the leaf spring 305 is in the state shown in FIG. 6B, and the HDD fixing device 300 shown in FIG. Specifically, by moving the operation plate 303 in the direction away from the connection substrate 212, the rotation shaft 304f moves. As shown in FIG. 11 (b), the rotating shaft 304f rotates about the rotating shaft 304c while drawing the locus of the arrow Q. At this time, as shown in FIG. 11C, the rotation shaft 304f slides inside the slide hole 303a, thereby absorbing the difference between the rotation locus of the rotation shaft 304f and the movement locus of the operation plate 303. . As a result, the link plate 304b rotates.

  As the link plate 304b rotates, the rotation shaft 304e rotates about the rotation shaft 304c while drawing the locus of the arrow P in the drawing. As the rotation shaft 304e rotates, the connecting portion 307b connected to the rotation shaft 304e moves. At this time, as shown in FIG. 11C, the rotation shaft 304e slides inside the slide hole 307c, thereby absorbing the difference between the rotation locus of the rotation shaft 304e and the movement locus of the connecting portion 307b. Further, as shown in FIG. 6B, the spring end 305a and the spring pressing portion 303b are separated from each other, and the leaf spring 305 is in a standard state.

  Such an operation leads to the state shown in FIG. 5 from the state shown in FIG. In the state shown in FIG. 5, the HDD 100 is pressed and fixed between the pressing member 306 and the guide rail 302 on the opposite side. Further, a force is applied so as to be pressed against the operation plate 303 by the deformation of the convex portion 306 a formed on the pressing member 306. In this way, by completely connecting the HDD 100 to the connection board 212 and then holding the HDD fixture 300, the HDD 100 is held in a state where the connection between the HDD 100 and the connection board 212 is incomplete. Can be avoided.

  By such an operation of the link mechanism 304, the operation plate 303 and the ejector 307 can be operated in conjunction with each other, and the movement direction of the operation plate 303 and the movement direction of the ejector 307 can be reversed. Thus, when the HDD 100 is inserted into the HDD fixture 300, the operation unit 303c can be pushed into the HDD fixture 300. If the operation unit 303c is pushed into the HDD fixture 300, the surface of the guide rail 302 on which the bottom surface of the HDD 100 slides can be connected to the operation unit 303c. Thereby, when the HDD 100 is inserted from the insertion end 310, the HDD 100 can be prevented from colliding with the end portion of the guide rail 302 and being damaged.

  When removing the HDD 100 from the HDD fixture 300, the operation plate 303 is pushed in the state shown in FIG. That is, by moving the operation plate 303 in a direction approaching the connection board 212, the leaf spring 305 is changed from the state shown in FIG. 6B to the state shown in FIG. 6C, and the HDD 100 is held by the pressing member 306. Canceled. Further, the link mechanism 304 performs the reverse operation, and first, as shown in FIG. 10, the contact portion 307 a of the ejector 307 contacts the HDD 100. Further, by bringing the operation plate 303 closer to the connection board 212, the contact portion 307a pushes the HDD 100, the interface connector of the HDD 100 is removed from the connector of the connection board 212, and the connection between the HDD 100 and the connection board 212 is released. Is done. Accordingly, the state shown in FIG. 5 is reached through the state shown in FIG. 10 to the state shown in FIG.

  As described above, the HDD fixture 300 according to the present embodiment can simultaneously perform the unlocking and ejection of the HDD 100 by simply pressing the operation plate 303. When it is necessary to pull the operation unit 303c during the ejecting operation, the ejected HDD 100 hits the operator's finger. On the other hand, in the present embodiment, the worker only has to push the operation unit 303c with his / her palm, and even if the HDD 100 is ejected and jumps out toward the insertion end 310, it hits the worker's palm. Therefore, the operation can be performed more safely than pulling the operation plate 303.

  In the above description, one HDD fixing device 300 is fixed to one cell 211 and one HDD 100 is inserted. However, a plurality of HDD fixing devices 300 are fixed to one insertion hole, and a plurality of HDD fixing devices 300 are fixed. HDD 100 may be inserted. In the above description, an HDD fixture for a 3.5-inch HDD has been described as an example. However, the present invention can also be applied to HDDs of other sizes such as 2.5 inches and 1 inch. Furthermore, in the above description, in order to avoid incomplete connection between the HDD 100 and the connection board 212, an example in which an operator operates the operation unit of the operation plate 303 after the HDD 100 is connected to the connection board 212 has been described. . However, when the HDD 100 is completely connected to the connection board 212, the leaf spring 305 is automatically in a standard state, and the HDD 100 can be held.

  For example, in the state shown in FIG. 10, that is, in a state where the HDD 100 is completely connected to the connection board 212, the leaf spring 305 is curved and formed on the slope of the spring end 305 a and the spring pressing portion 303 b of the operation plate 303. If the inclined surface is in contact, a pressing force is applied from the spring end portion 305a to the spring pressing portion 303b by the repulsive force of the leaf spring 305. Thereby, the operation plate 303 is pushed, and the leaf spring 305 and the operation plate 303 are in the state shown in FIG. Such a configuration is possible by adjusting the position of the spring pressing portion 303b in the operation plate 303. In the above description, the leaf spring 305 is flat in the standard state. However, the leaf spring 305 is warped so as to press the HDD 100 in the standard state, and is flattened by the pressing force by the spring pressing portion 303b. It can also be configured to be spaced apart.

  Further, the mechanism of the link mechanism 304 may be other than the above-described configuration, and any configuration may be used as long as the operation plate 303 and the ejector 307 move in conjunction with opposite directions. For example, by connecting the operation plate 303 and the connecting portion 307b via a gear, the operation plate 303 and the ejector 307 can be moved in conjunction with each other in the reverse direction. Can be obtained.

  Also. In the above description, when testing the HDD 100, the HDD 100 downloads the test program and information such as various parameters from the test computer 202 and executes the test. It may be stored in a memory or the like, and the test computer 202 may only transmit a command for executing the test. Connection board 212 does not need to have a connector corresponding to the power connector of HDD 100, and power may be supplied to HDD 100 from other than connection board 212. Further, power may be supplied from the interface connector of the HDD 100.

  Furthermore, in the above description, an example of the HDD fixture 300 for fixing the HDD in the HDD test apparatus 200 has been described. However, the present invention is not limited to the test apparatus, and for example, an electronic device having an HDD such as a server, personal computer, hard disk recorder, It can also be used as a jig for fixing and connecting the HDD in the device. Further, it can be used as a jig for fixing the HDD 100 during servo writing of the HDD 100. Further, it can be used as a jig for fixing the HDD with the connection board 212 removed. In this case, the groove 302 and the board fixing bracket 308 formed in the guide rail 302 are not particularly necessary.

  In the above description, the example in which the cross-sectional shape of the pressing member 306 is a shape as shown in FIG. 7 has been described. As described above, this is preferable because the HDD 100 can be pressed downward by this, but the pressing surface of the pressing member 306 may be a flat surface. Further, it may be pressed by inserting a conical elastic body into a screw hole of the HDD 100.

  In the above description, the example in which the connection substrate 212 is released by pulling the operation unit 303c from the state of FIG. 5 has been described. In this case, since it is not necessary to form a movement path for the operation plate 303 other than the direction in which the operation plate 303 is moved in the normal operation, the operation unit 303c moves between the state of FIG. 4 and the state of FIG. As long as the substrate fixing unit 308 is pushed up by moving the operation unit 303c to a range other than the range, the same effect as described above can be obtained. For example, the case where the operation unit 303c is further pushed in from the state of FIG. 4, the case where the operation unit 303c is moved in a direction other than the horizontal direction on the plate surface, the case where the operation unit 303c is rotated, or the like can be considered.

  Furthermore, in the above description, by using the elastic body 309, the range of the normal operation of the operation unit 303c is distinguished from the range for releasing the connection board 212. In this case, it is preferable because the normal operation range of the operation unit 303c can be easily distinguished from other ranges, but for example, the ejector 307 and the guide rail 302 are fitted in the state of FIG. 4 or FIG. As described above, unevenness may be formed. Further, the example in which the ejector 307 contacts the elastic body 309 and pushes up the substrate fixing portion 308 has been described. In this case, it is preferable because the number of parts can be reduced. However, the member that contacts the elastic body 309 and the member that pushes up the board fixing portion 308 may be members that interlock with the operation portion 303c, and may be formed separately from the ejector 307. good.
