Description

  The present invention relates to a glass plate accommodation jig for accommodating a glass plate, for example, when performing a glass plate cleaning process.

  As is well known, in recent years, with the development of electronic devices and the like, flat panel displays (FPD) such as liquid crystal displays, plasma displays, field emission displays (including surface emission displays) and electroluminescence displays, and sensor substrates, Or various glass products, such as a cover for semiconductor packages, such as a solid-state image sensor and a laser diode, and also the board | substrate of a thin film compound solar cell, are used. Various types of glass plates are being made thinner. As such a situation progresses, the glass plates become flexible due to their thinness.

  On the other hand, not only for glass plates, but for plate-like bodies, for example, a jig that accommodates a plurality of plate-like bodies together is used to improve work efficiency during processing such as cleaning and drying, and transportation. The Such an accommodation jig normally accommodates a plurality of glass plates in a vertical posture in a state of being arranged in the thickness direction so that a gap is formed between them, and supports the plurality of glass plates from both sides. A side support groove and a lower support groove for supporting a plurality of glass plates from below are provided (for example, Patent Document 1).

Japanese Utility Model Publication No. 4-48540

  However, a flexible plate-like body such as the above-described thinned glass plate is flattened due to the flexibility during processing and transportation in a state of being accommodated in such a jig. It is difficult to maintain a simple shape. For this reason, the adjacent glass plates are brought into contact with each other, resulting in problems such as damage or damage to the glass plates.

  From such a viewpoint, the 1st subject of this invention is suppressing the contact between the several glass plates accommodated in the glass plate accommodation jig | tool.

  In addition, when a plate-like body such as a glass plate is housed in a jig as described above and is lifted from the washing tank after washing, a cleaning liquid (for example, water) is present around the contact area with the jig. In some cases, it remained, and due to this, it could not be sufficiently dried.

  From such a point of view, the second problem of the present invention is to facilitate drying after washing the glass plate accommodated in the glass plate accommodation jig.

  The glass plate accommodation jig of the present invention created to solve the first problem is accommodated in a state in which a plurality of glass plates are arranged in a thickness direction so that a gap is formed between them in a vertical posture. A side support portion formed with side support grooves for supporting the plurality of glass plates from both sides, and a lower support portion formed with lower support grooves for supporting the plurality of glass plates from below. The glass plate accommodation jig | tool provided with this has a flexible strip | belt arrange | positioned along the main surface of the said glass plate in the clearance gap between the said some glass plates. Here, the term “flexible strip” includes a plastic rod, a piano wire, a straw, and the like in addition to a thread, a string, a band, a wire, and the like (hereinafter the same).

  According to such a configuration, even if the glass plates cannot maintain a flat shape due to the flexibility during the processing and transportation of the plurality of glass plates accommodated in the jig, the mutual contact between the glass plates. Unauthorized deformation of the glass plate is suppressed by the flexible strips arranged in the gaps therebetween. Thereby, the situation where the several glass plate accommodated in the said jig | tool contacts each other is prevented, and malfunctions, such as a contact damage being attached to a glass plate, are avoided. In addition, since the strip is flexible, even if the glass plate is deformed, the strip can be deformed following the deformation of the glass plate. Therefore, the glass plate is caused by the contact between the glass plate and the strip. Reduces the possibility of damage. In addition, it is preferable that the hardness of a flexible strip is lower than the hardness of a glass plate.

  Said structure WHEREIN: It is preferable that the said flexible strip is arrange | positioned so that it may pass through the clearance gap between the center area | regions in the main surface which the said adjacent glass plate opposes.

  Since the central region of the main surface of the glass plate is the region farthest from the supported peripheral portion, large deflection occurs and adjacent glass plates are likely to contact each other. Accordingly, when the flexible strip passes through the gaps corresponding to the central region, the contact between the glass plates can be efficiently suppressed.

  Said structure WHEREIN: It is preferable that a pair of said flexible strip cross | intersects in the clearance gap between the said center area | regions.

  If it is the way of arrangement | positioning of this flexible strip, the contact of the center area | regions of the main surface of a glass plate can be more reliably and efficiently suppressed by a flexible strip.

  Said structure WHEREIN: It is preferable that the plate | board thickness of the said glass plate is less than 200 micrometers.

  If the thickness of the glass plate is less than 200 μm, the flexibility of the glass plates becomes remarkable, and the possibility that the glass plates come into contact with each other increases. Therefore, the above-described configuration is more effective.

  Said structure WHEREIN: While the cross-sectional shape of the said side support groove is V shape, it is preferable that the cross-sectional shape of the said lower support groove is U shape.

  If the cross-sectional shape of the side support groove is V-shaped, the glass plate can be more reliably supported from both sides without causing backlash, and when the jig is lifted from the cleaning tank, The cleaning liquid between the support grooves is less likely to remain by dropping due to its own weight. Moreover, if the cross-sectional shape of the lower support groove is U-shaped, it is possible to prevent the cleaning liquid from remaining between the glass plate and the lower support groove when pulled up from the cleaning tank. As a result of the above, it is easy to dry the glass plate after washing while ensuring stable support of the glass plate.

  The glass plate accommodation jig of the present invention created in order to solve the second problem accommodates a plurality of glass plates arranged in a thickness direction so that a gap is formed between them in a vertical posture. A side support portion formed with side support grooves for supporting the plurality of glass plates from both sides, and a lower support portion formed with lower support grooves for supporting the plurality of glass plates from below. The cross-sectional shape of the side support groove is V-shaped, and the cross-sectional shape of the lower support groove is U-shaped.

  According to such a configuration, since the cross-sectional shape of the lower support groove is U-shaped, it is possible to prevent the cleaning liquid from remaining between the glass plate and the lower support groove when the lower support groove is pulled up from the cleaning tank. Moreover, since the cross-sectional shape of the side support groove is V-shaped, the glass plate can be more reliably supported from both sides without causing backlash, and when the jig is lifted from the cleaning tank, The cleaning liquid between the side support grooves falls by its own weight and hardly remains. As a result of the above, it is easy to dry the glass plate after washing while ensuring stable support of the glass plate.

  As mentioned above, according to this invention, the contact between the several glass plates accommodated in the glass plate accommodation jig | tool can be suppressed.

  Moreover, according to this invention, the drying after washing | cleaning with respect to the glass plate accommodated in the glass plate accommodation jig | tool can be made easy.

The V-shaped angle α of the cross-sectional shape in the side support groove 5a is preferably 6 ° to 26 °, for example. When the V-shaped angle α is less than 6 °, the glass plate 2 cannot be sufficiently inserted into the side support groove 5a, and the insertion work may be difficult. When the V-shaped angle α exceeds 26 °, the glass plate 2 may not be sufficiently supported, and the glass plate 2 may be unduly bent. Further, the width of the side support groove 5a is increased, the number of side support grooves 5a that can be formed on the side support rod 5 having the same length is reduced, and the glass plate 2 that can be accommodated in the glass plate accommodation jig 1 having the same dimensions. Decrease. From these viewpoints, the V-shaped angle α is more preferably 8 ° to 24 °, and most preferably 10 ° to 22 °.

  Further, the depth d1 of the side support groove 5a is preferably, for example, 14 mm to 26 mm. When the depth d1 is less than 14 mm, the glass plate 2 cannot be sufficiently inserted into the side support grooves 5a, and the glass plate 2 may come out. When the depth d1 exceeds 26 mm, drying after washing may be insufficient. From these viewpoints, the depth d1 of the side support groove 5a is more preferably 16 mm to 24 mm, and most preferably 18 mm to 22 mm.

  As shown in FIG. 2, the upper support bar 7 is provided with a plurality of linear upper support grooves 7a at predetermined intervals in the longitudinal direction thereof. The cross-sectional shape of the upper support groove 7a is also V-shaped. The V-shaped angle of the cross-sectional shape in the upper support groove 7a and the depth of the upper support groove 7a are the same as in the case of the side support groove 5a.

  As shown in an enlarged view in FIG. 8, the cross-sectional shape of the lower support groove 6a is U-shaped. In the present embodiment, the lower portion of the U-shaped section of the lower support groove 6a (the cross-sectional shape of the bottom surface of the lower support groove 6a) is a perfect circular partial arc shape, but is not limited to this, and the width direction It may be a smooth curved shape whose depth gradually increases toward the center. The radius of the U-shaped partial arc-shaped portion of the cross-sectional shape in the lower support groove 6a is preferably, for example, 1.9 mm to 3.1 mm. When the radius is less than 1.9 mm, the cleaning liquid remains between the glass plate 2 and the groove bottom after cleaning, and drying may be insufficient. When the radius exceeds 3.1 mm, the glass plate 2 cannot be sufficiently supported, and the glass plate 2 may be bent unjustly. From these viewpoints, the radius of the U-shaped partial arc-shaped portion of the cross-sectional shape in the lower support groove 6a is more preferably 2.1 mm to 2.9 mm, and most preferably 2.3 mm to 2.7 mm.

  Further, the depth d2 of the lower support groove 6a is preferably, for example, 14 mm to 26 mm. When the depth d2 is less than 14 mm, the glass plate 2 cannot be sufficiently inserted into the lower support groove 6a, and the glass plate 2 may escape.

From these viewpoints, the depth d2 of the lower support groove 6a is more preferably 16 mm to 24 mm, and most preferably 18 mm to 22 mm.

  The width w of the lower support groove 6a is preferably 2 mm to 6 mm, for example. When the width w is less than 2 mm, the cleaning liquid tends to remain between the glass plate 2 and the side surface of the lower support groove 6a after cleaning, and drying may be insufficient. When the width w exceeds 6 mm, the glass plate 2 cannot be sufficiently supported, and the glass plate 2 may be bent unjustly. Moreover, the lower support groove 6a which can be formed in the lower support rod 6 of the same length decreases, and the glass plate 2 which can be accommodated in the glass plate accommodation jig 1 of the same dimension decreases. From these viewpoints, the width w of the lower support groove 6a is more preferably 2.5 mm to 5 mm, and most preferably 3 mm to 4 mm.

When the V-shaped angle β is less than 24 °, not only the flexible strip 8 is not sufficiently inserted but also the insertion operation may be difficult. If the V-shaped angle β exceeds 36 °, the flexible strip 8 may be displaced during use. From these viewpoints, the V-shaped angle β is more preferably 26 ° to 34 °, and most preferably 28 ° to 32 °.

  Next, the usage method of the glass plate accommodation jig | tool 1 of this embodiment is demonstrated.

  First, before arranging the glass plate 2 in the glass plate receiving jig 1, the attachment member (not shown) to which the upper support rod 7 is fixed is removed from the frame 3 of the glass plate receiving jig 1. ing. Next, a plurality of glass plates 2 are arranged in the glass plate accommodation jig 1. That is, a plurality of glass plates 2 are inserted into the glass plate accommodation jig 1 in a vertical posture.

  After all the glass plates 2 are arranged in the glass plate receiving jig 1, an attachment member to which the upper support bar 7 is fixed is attached to the frame body 3. This completes the installation of the glass plate 2 to the glass plate receiving jig 1.

  In this state, the glass plate accommodation jig 1 is immersed in the cleaning liquid in the cleaning tank, and the glass plate 2 is cleaned. Then, the glass plate accommodation jig | tool 1 is pulled up from a washing tank, and the washing | cleaning liquid adhering to the glass plate accommodation jig | tool 1 and the glass plate 2 is dried with a drying apparatus.

  Then, the glass plate 2 is taken out from the glass plate accommodation jig 1 in the reverse procedure to the above. That is, the attachment member to which the upper support bar 7 is fixed is removed from the frame 3, and the glass plate 2 is taken out from the glass plate accommodation jig 1.

  The glass plate accommodation jig 1 of the present embodiment configured as described above can enjoy the following effects.

  Even if the glass plate 2 cannot maintain a flat shape due to its flexibility during the processing and transportation of the plurality of glass plates 2 housed in the glass plate housing jig 1, The flexible strip 8 disposed in the gap suppresses undue deformation of the glass plate 2. Thereby, the situation where the several glass plate 2 accommodated in the glass plate accommodation jig | tool 1 contacts mutually is prevented, and malfunctions, such as a contact damage being attached to the glass plate 2, are avoided. Further, since the strip 8 is flexible, even if the glass plate 2 is deformed, the strip 8 can be deformed following the deformation of the glass plate 2, so that the contact between the glass plate 2 and the strip 8 is possible. The possibility of the glass plate 2 being damaged due to the above is reduced. The hardness of the flexible strip 8 is preferably lower than the hardness of the glass plate 2.

  Moreover, since the outer diameter of the flexible strip 8 is small, the flexible strip 8 can be wound or tied and fixed, and the flexible strip 8 can be fixed to the glass plate receiving jig 1. The body 8 can be easily attached and detached. Thereby, it is easy to change the way of disposing the flexible strip 8 along with the change of the dimension of the glass plate 2 or the like.

  Moreover, as shown in FIG. 8, since the cross-sectional shape of the lower support groove 6a in the glass plate accommodation jig 1 is U-shaped, when pulled up from the cleaning tank, the glass plate 2 and the lower support groove 6a indicated by a two-dot chain line are shown. It can suppress that a washing | cleaning liquid remains between. That is, if the lower support groove 6a is V-shaped like the side support grooves 5a, the cleaning liquid remains between the glass plate 2 and the lower support groove 6a. However, in this embodiment, since the cross-sectional shape of the lower support groove 6a is U-shaped, such a problem does not occur. This facilitates drying after cleaning the glass plate 2.

  Moreover, as shown in FIG. 6, since the cross-sectional shape of the side support groove 5a is V-shaped, the glass plate 2 shown with a dashed-two dotted line can be more reliably supported from both sides, without producing shakiness. In this case, even if the cross-sectional shape of the side support groove 5a is V-shaped, the cleaning liquid between the glass plate 2 and the side support groove 5a falls due to its own weight, so that it is not affected by the capillary phenomenon. As a result, it is easy to dry the glass plate 2 after cleaning while ensuring stable support of the glass plate 2.

  In addition, this invention is not limited to the above description, A various deformation | transformation is possible within the range of the technical idea. For example, in the above-described embodiment, the flexible strip is hung on the support bar that supports the glass plate, but may be hung on a frame body or other member other than the support bar.
