Description

  The present invention relates to a storage jig used when a magnetic disk glass disk is stored in a disk case.

  Currently, disk-shaped disks are widely used as recording media such as hard disks and optical disks and substrates for such recording media. Such a disk is required to ensure its surface smoothness as the recording density increases. A disk is generally manufactured through a shape processing process, a grinding process, a polishing process, and a final inspection process. And inspection is implemented between each process, and when abnormality is discovered by this inspection, investigating a cause and dealing with this are performed. For example, when a scratch or foreign matter is found on the surface of the disk that has undergone the polishing process due to foreign matter mixed into the polishing pad on the upper surface plate of the polishing apparatus, the upper surface plate polishing pad is replaced. In order to meet the demands for mass production and reduction of manufacturing costs, such manufacturing management is performed in units of one lot, for example, 125 disks processed at one time in each manufacturing process.

  By the way, the discs are easily damaged, and the thickness is usually as thin as about 0.6 to 1.5 mm. Therefore, the discs are in contact with each other during the processing in each manufacturing process and the storage and transportation of the discs after each step. Or contact with other things to prevent damage. Therefore, a disk case for storing a plurality of disks at a predetermined interval is used for processing, storing and transporting the disks.

As such a disk case, for example, a disk case described in JP-A-2001-247186 is known. FIG. 7A shows an example of a conventional disk case. A disc case 10 shown in FIG. 7A is provided with a plurality of ribs 12 on the side wall 11 and a groove 13 for accommodating the disc 1 is formed by the gaps. Then, the discs 1 are inserted from the opened upper side, and a large number of discs 1 are arranged and stored in an upright state.
JP 2001-247186 A

  In recent years, the number of discs that can be stored in a disc case tends to increase in order to meet demands for mass production and reduction of manufacturing costs. On the other hand, due to the problem of working space and storage space, there is a demand for smaller and even smaller disk cases. For these reasons, it is required to narrow the groove (gap between ribs) provided in the disk case and increase the disk storage density.

  However, if the interval between the grooves 13 is narrowed, when the disc 1 is stored in the disc case 10, the discs are brought into contact with each other as shown in FIG. There is a problem in workability such as inserting a disc 1 or inserting the disc 1 at an angle as shown in FIG. If the main surface is damaged due to contact between the disks, the disk is judged to be defective by inspection. Also, if dust is generated due to contact between disks and the particles adhere to other disks, it may cause a head crash or thermal asperity, so that a convex part is formed on the surface of the magnetic disk and an appropriate glide height is obtained. And cause thermal asperity.

  One solution to the above problem is to set every other disc in the groove of the disc case. However, since the number of disk cases is twice as large as the number of disks, this is in conflict with the space problem. As another solution, it is conceivable to widen the gap between the grooves, but the problem of the space is also caused.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a storage jig that can be securely stored without contacting the disks even when the gap between the grooves of the disk case is narrow.

  A typical configuration of the magnetic disk glass disk storage jig according to the present invention is that a glass disk is inserted from above into a gap between a plurality of ribs provided on the side wall, and a plurality of glass disks are erected. A jig used for a disk case for storing an array, comprising: a main body placed on the disk case; and a plurality of guide portions provided on the main body, wherein the guide portion inserts a glass disk The distance between the guide portions is an integral multiple of the distance between the ribs, and the main body is movable relative to the disk case in the glass disk arrangement direction. It is characterized by that. As a result, the discs are inserted at intervals that are an integral multiple of the interval between the ribs, which makes the work easier, and if the disc is already in the disc, or if the disc is inserted at an angle. I don't get lost. Further, since the disc can be inserted almost vertically by the guide portion, the disc does not tilt and hit the disc already stored. By shifting the storage jig, the disk can be stored tightly and surely in the intervals of all the ribs of the disk case having a high storage density.

  The main body may be a frame body, and the guide portion may be a pair of cutout portions provided inside two opposing sides of the frame body. This is because it is sufficient to support the peripheral edge to guide the disk, and the visibility of the already stored disk is improved by using the main body as a frame.

  The main body is longer than the disk case in the arrangement direction of the glass disks, and includes a defining portion that contacts the disk case at both ends in the glass disk arrangement direction, and the defining portion at one end contacts the disk case The gaps of the ribs corresponding to the guide portions may be different when the defining portion at the other end is in contact with the disk case. When the distance between the guide portions is twice the distance between the ribs, the disk case and the main body can be positioned relatively simply.

  One of the disk case and the main body is provided with an engaging portion, and the other is provided with an engaging portion, and the engaging portion and the engaging portion can position the disk case and the main body at a plurality of positions relatively. Then, the gaps of the ribs corresponding to the guide portions may be different at each position. This is an example of a configuration for relatively positioning the disc case and the main body so that the disc can be inserted into the intervals of all the ribs when the interval of the guide portions is three times or more of the interval of the ribs.

  By using the storage jig according to the present invention, even if the gap between the grooves of the disk case is narrow, the disk can be reliably stored without hitting the disks. Accordingly, the storage density of the disk case can be increased, the work space and the storage space can be reduced, and the production efficiency can be improved.

[First embodiment]
A description will be given of a first embodiment of a glass disk storage jig according to the present invention. FIG. 1 is an external perspective view of a storage jig and a disk case, FIG. 2 is a front view and a side view illustrating a state where the storage jig is placed on the disk case, and FIG. 3 is a disk case using the storage jig. FIG. 4 is a diagram for explaining a state in which a disc is erroneously inserted.

  In this embodiment, the up and down direction refers to the up and down direction in the normal usage mode of the storage jig or the disk case, and is not necessarily the up and down direction with respect to the direction of gravity. In the following description, specific materials, shapes, the number of ribs, and the like are examples for facilitating understanding, and the present invention is not limited thereto.

  As shown in FIG. 1, the disk case 10 includes a plurality of ribs 12 extending in the vertical direction on opposing side walls 11, and a groove 13 for housing the disk 1 is formed by a gap between the ribs 12. ing. In this embodiment, the disk 1 is a disk-shaped glass disk. By inserting the disk 1 into the groove 13 from above the disk case 10, a large number of disks 1 are arranged and stored.

  The storage jig 20 includes a frame body 21 as an example of a main body, a step portion 22, and a plurality of guide portions 23 provided on the frame body 21. Both ends of the frame 21 in the arrangement direction of the disks 1 constitute a defining portion 24 that makes a relative positioning between the disk case 10 and the storage jig 20 by contacting the disk case 10.

  The step portion 22 is recessed with respect to the outer shape of the frame body 21, and the frame body 21 is placed so as to cover the disk case 10 when the storage jig 20 is placed on the disk case 10. . Further, the frame body 21 has a width substantially equal to the width of the disk case 10 in the arrangement direction of the glass disks and is longer than the length of the disk case 10. Accordingly, the storage jig 20 cannot move in the width direction with respect to the disk case 10 as shown in FIG. 2A, but moves in the length direction as shown in FIG. Can do. The movement in the length direction is restricted by the defining portion 24 coming into contact with the disk case 10.

  The interval between the guide portions 23 is an integral multiple of the interval between the grooves 13, and is twice in this embodiment. The guide portions 23 are a pair of cutout portions provided on the inner sides of two opposite sides of the frame body 21, and are set to have a width and a thickness that allow the disc 1 to pass through and regulate the inclination angle. ing. The guide part may be a long hole having a slit or spindle-shaped opening. However, in order to guide the disc, it is sufficient to support the peripheral portion, and by opening the central portion using the main body as a frame, the visibility of the disc already stored can be improved.

  Next, the operation of storing the disk 1 in the disk case 10 using the storage jig 20 will be described with reference to FIG. In FIG. 3, the number of discs stored in the disc case 10 is reduced to simplify the explanation.

  First, as shown in FIG. 3A, the storage jig 20 is placed on the disk case 10, and positioning is performed by abutting the defining portion 24 at one end against the disk case 10. When the discs 1 are inserted into the guide portion 23 in order, every other disc 1 is inserted into the groove 13 of the disc case 10.

  At this time, since the interval between the guide portions 23 is set to be twice the interval between the grooves 13, the operator can easily identify the groove 13 (guide portion 23) into which the disk 1 has already been inserted. Can be prevented from being inserted. Similarly, since the width of the guide portion 23 is wide, as shown in the plan view of FIG. 4 (a), it is difficult to make an error of inserting both ends of the disk 1 into different guide portions 23 at an angle. However, since it is restricted by the width of the notch portion of the guide portion 23 and cannot be inserted, mistakes can be reliably prevented. Further, as shown in the side view of FIG. 4B, since the inclination of the disk 1 is regulated by the guide portion 23, the disk to be inserted and the already inserted disk do not come into contact with each other. Can be prevented. For these reasons, even if the gap between the grooves 13 of the disk case 10 is narrow, the disks 1 can be reliably stored without being in contact with each other, and workability and production efficiency can be improved.

  Next, as shown in FIG. 3 (b), the storage jig 20 is moved in the arrangement direction of the disks 1, and the positioning part 24 at the other end is brought into contact with the disk case 10 for positioning. As a result, the guide portion 23 moves to a position corresponding to the non-inserted groove 13. Then, when the disc 1 is inserted into the guide portion 23 in order, the disc 1 is inserted into all the grooves 13 of the disc case 10 as shown in FIG. In this manner, the disc 1 can be tightly stored in the groove 13 of the disc case 10 with a narrow interval while the disc 1 is inserted into the guide portion 23 with a wide interval. Therefore, the storage density of the disk case 10 can be increased to reduce the work space and storage space, thereby improving the production efficiency.

  Here, the positional relationship between the guide unit 23 and the defining unit 24 will be described again. The number of grooves 13 in the disc case 10 shown in FIG. 3A is an even number, and the distance from the defining portion 24 at one end to the first guide portion 23 is the second from the end on one end side of the disc case 10. It is the distance to the groove 13. In this case, as shown in FIG. 3B, the distance from the defining portion 24 at the other end to the first guide portion 23 is also the distance from the end at the other end of the disk case 10 to the second groove 13. It is necessary to. If the number of grooves 13 in the disc case 10 is an odd number, the distance from the defining portion 24 at the other end to the first guide portion 23 is the first groove 13 from the end on the other end side of the disc case 10. It is necessary to be the distance to. Explaining these comprehensively, the guide portion 23 has a corresponding groove when the defining portion 24 at one end abuts the disc case 10 and when the defining portion 24 at the other end abuts the disc case 10. What is necessary is just to comprise so that 13 may differ. With this configuration, when the distance between the guide portions 23 is twice the distance between the grooves 13, the disk case 10 and the storage jig 20 can be relatively simply positioned.

  The material of the disk case 10 and the storage jig 20 (especially around the guide portion 23) as described above is a metal or resin that can withstand the use environment such as processing liquid and processing temperature used for processing the stored disk 1. It is made of a material such as In particular, from the viewpoint of manufacturing cost and finishing accuracy, it is preferable to integrally mold with resin. As such a resin, a general resin such as a polyacetal resin, polyolefins such as various polyethylenes and polypropylenes, polyvinyl chloride, and Teflon (registered trademark) (PTFE) can be used. In particular, when the disk case is manufactured by a normal injection molding method, examples of the resin include polycarbonate, polyamide, thermotropic liquid crystal polymer (LCP), polyetheretherketone (PEEK), polyetherketone (PEK), and PEEK. Alloy resins (for example, PEEK / thermotropic liquid crystal polymer, PEEK / polybenzimidazole (PBI), etc.), polybenzimidazole (PBI), polyphenylene sulfide (PPS), polyethersulfone (PES), polyetherimide (PEI), It is preferable to use a fluororesin such as polytetrafluoroethylene (PTFE).

  The disk 1 stored in the disk case 10 is not particularly limited. For example, a hard disk substrate or an optical disk substrate formed of glass, crystallized glass, ceramics, silicon, carbon, aluminum, aluminum alloy, titanium, or the like. Examples thereof include a magneto-optical disk substrate, a hard disk, an optical disk, a magneto-optical disk, and a silicon wafer manufactured using these substrates. Further, the size of the disk 1 stored in the disk case 10 is not particularly limited. For example, hard disk substrates have various sizes such as 65 mmφ (2.5 inches), 84 mmφ (3.0 inches), 95 mmφ (3.5 inches), and before and after processing in each process. The disc size and thickness may be different. In such a case, the disc case 10 corresponding to each size can be obtained by appropriately setting the interval and height of the side walls 11, the interval of the ribs 12, the width of the grooves 13, and the like. Also, the disc case 10 may be colored differently depending on the type and size of the disc 1 to be stored or the processing applied to the disc 1. Moreover, you may color different colors for every process or atmosphere in which a disk case is used. Further, when the disc case is used in a clean room, different colors may be colored according to the cleanliness of the clean room.

[Second Embodiment]
The second embodiment of the glass disk storage jig according to the present invention will be described. FIG. 5 is an explanatory view of the main part of the storage jig and the disk case according to the present embodiment, and FIG. 6 is a view for explaining the operation of storing the disk in the disk case using the storage jig. Portions that overlap with the description of the embodiment are given the same reference numerals and description thereof is omitted.

  As shown in FIG. 5, in this embodiment, the distance between the guide portions 23 is three times the distance between the grooves 13. The guide portion 23 of the storage jig 20 is provided with a convex portion 25 as an example of a locking portion, and the disc case 10 is provided with a concave portion 14 as an example of an engaging portion. A plurality of recesses 14 are provided in the arrangement direction of the disks 1, and three in this embodiment. The interval between the recesses 14 is set to be equal to the interval between the grooves 13 of the disk case 10. Note that the defining portion 24 is in a positional relationship where it does not contact the disk case 10 even when the convex portion 25 is fitted to any of the concave portions 14. With this configuration, the storage jig 20 can be positioned at a plurality of positions relative to the disc case 10, and the groove 13 corresponding to the guide portion 23 can be different at each position.

  In this embodiment, the number of the recesses 14 is three. However, the interval between the guides 23 is further increased (for example, five times the interval between the grooves 13), and the number of the recesses 14 is increased accordingly (for example, five). You may do it. Further, the engaging portion and the engaging portion are not limited to the convex portion and the concave portion, and a notch using an elastic member may be used.

  Next, the operation of storing the disk 1 in the disk case 10 using the storage jig 20 will be described with reference to FIG. In FIG. 6, for ease of explanation, the number of discs stored in the disc case 10 is reduced.

  First, as shown in FIG. 6A, the storage jig 20 is placed on the disk case 10, and the convex portion 25 is fitted to the first concave portion 14, whereby the storage jig 20 and the disk are fitted. The case 10 is positioned. When the discs 1 are inserted into the guide portion 23 in order, the discs 1 are inserted into every two grooves 13 of the disc case 10. At this time, since the interval between the guide portions 23 is set to three times the interval between the grooves 13, the interval between the guide portions 23 is wider than that in the first embodiment, so that workability and production efficiency can be improved. it can.

  Next, as shown in FIG. 6 (b), the storage jig 20 is moved in the arrangement direction of the disks 1, and the convex portion 25 is fitted with the second concave portion 14 to be positioned. As a result, the guide portion 23 moves to a position corresponding to the non-inserted groove 13. Then, the disc 1 is inserted into the guide portion 23 in order. Further, as shown in FIG. 6C, the disc 1 is sequentially inserted into the guide portion 23 in a state where the storage jig 20 is moved and the convex portion 25 is fitted to the third concave portion 14. As a result, the disc 1 is inserted into all the grooves 13 of the disc case 10.

  In this manner, the disc 1 can be tightly stored in the groove 13 of the disc case 10 with a narrow interval while the disc 1 is inserted into the guide portion 23 with a wide interval. Therefore, the storage density of the disk case 10 can be increased to reduce the work space and storage space, thereby improving the production efficiency.

  The present invention can be used as a storage jig used when a glass substrate for a magnetic disk is stored in a substrate case.
