- Substrate transport container inner wall structure of the transport container, and bottom raising member used for the transport container
- the present invention is suitable for use in a substrate carrying container suitable for accommodating and carrying a large number of substantially rectangular liquid crystal glass substrates and the like, an inner wall structure of the carrying container, and the carrying container. It is related with the bottom raising member made.
- a substrate such as a glass substrate for liquid crystal
- the substrates are not brought into contact with each other, contamination is prevented, and the substrate is not cracked or chipped.
- a substrate transfer container with a lid tightly fitted in a state in which a large number of sheets are accommodated is used so that it can be safely transferred in the state.
- a substantially rectangular parallelepiped container main body and a lid attached to the opening of the container main body are both formed from a synthetic foam resin (for example, a patent Reference 1).
- the glass substrate is transported in a state of being directly locked in the substrate support groove formed on the inner surface of the foamed synthetic resin container body. Therefore, if rubbing occurs on the glass substrate in the middle of transportation, the substrate support groove made of foamed synthetic resin is especially recommended as a result of the deterioration of the support groove portion on the inner surface of the container body that is in direct contact with the glass substrate. There existed a problem that a foam adhered to a glass substrate as garbage.
- Patent Documents 2 and 3 a container for transporting a substrate in which a protective film having a polyethylene film force is additionally provided inside the container body.
- a groove matching the shape of the groove 212a of the inner wall 211 on the foam side is formed on a previously formed flat polyethylene film 212B by thermoforming.
- the protective film 212b in which the grooves are formed is heat-sealed simultaneously with the molding of the grooves 212a, thereby covering the inner surface of the grooves 212a.
- the glass substrate directly contacts the inner wall 211 of the foam. Therefore, it is possible to prevent the formation of dust due to the foam.
- the width S of the pair of substrate locking grooves 212b facing each other is substantially the same from the upper part (inlet part of board insertion) to the lower part (final part of board insertion) of the box body. They are set to the same length.
- width S of the board locking groove is formed to be the same width from the entrance in the board insertion direction to the end of the inserted part in this way, when the board has been inserted with a slight inclination, There was a problem that the substrate was damaged.
- the distance E between the substrate locking grooves 212b at both ends is the final distance in the substrate insertion direction from the vicinity of the entrance in the substrate insertion direction. Since the distance E was the same until reaching the part, it was difficult to insert in the direction of the arrow unless the substrate G was inserted straight. Even if the glass substrate G is mounted without being damaged to the end, there is no space for play around the substrate, so when the container body is subject to vertical vibrations, the glass substrate There was also the problem of damaging G.

It is possible to store or move a substrate stored adjacent to and absorbed by a buffer gap formed between the inner wall surface and the inner wall surface in a more stable state. That is, for example, a glass substrate for liquid crystal is very thin and may be damaged by very slight stress.
- a container for transporting the substrate made of foamed resin most of the stress applied from the outside is absorbed by the casing made of foamed resin, but the stored substrate squeezes, etc. It is difficult to absorb the internal stress caused by only the holding groove formed on the inner wall surface of the housing.
- the substrate material or the substrate stored is carefully handled so that the substrate material or the substrate is not damaged. Damage due to internal stress generated in the substrate material or substrate occurs more frequently. In particular, this tendency increases as the liquid crystal becomes larger. In many cases, the substrate material or the substrate is damaged by such internal stress because the weight of the substrate or the substrate is related to the holding portion.
- the substrate material to be stored or the surface of the holding groove formed on the pair of side walls of the container main body which is a portion for holding the substrate The resin sheet for supporting the wall surface substrate is arranged with a slight gap, and the holding groove of the resin sheet for supporting the wall surface substrate is not fixed to the holding groove formed in the container body, however, Further, excessive deformation of the holding groove of the wall surface substrate supporting resin sheet is prevented by the holding groove formed in the container main body.
- the substrate material or the substrate to be stored has a certain degree of flexibility, and the substrate material or the substrate moves to the extent that the substrate material or the substrate moves within the flexibility range. Does not break.
- the substrate material or the substrate When transporting the substrate material or the substrate, the substrate material or the substrate must be fixed, but when the substrate is fixed, this fixed portion (specifically, the substrate material sandwiched by the holding grooves). Alternatively, stress concentrates on both ends of the substrate. Therefore, the substrate material during transportation In addition, the damage to the board is excluded as described above, except for the damage caused by careless handling such as dropping. Damage that seems to have originated at both ends of the crease increases.
- a slight gap is formed between the holding groove formed in the container main body and the holding groove of the wall surface substrate supporting resin sheet.
- the grease sheet is not fixed to the wall surface of the container main body, and this gap acts as a buffer space that allows deformation within the flexible range of the substrate material or substrate that is stored. . Therefore, by using the substrate transport container of the present invention, it is possible to prevent damage from the stored substrate material or both ends of the substrate.
- the wall substrate supporting resin sheet is fixed to the side wall of the container body.

If it falls into the container, it is impossible to stably supply the substrate transport container having the excellent characteristics as described above.
- a substrate manufacturer or the like often stores a substrate material or a substrate in the substrate transport container by an automatic device or the like, and transports the substrate material or the substrate as in the substrate transport container of the present invention. If the side wall shape of the foamed resin casing with the holding groove for holding the substrate is substantially the same as the surface shape of the wall surface substrate supporting resin sheet placed on this surface, mechanical In addition, it may be difficult to recognize the presence or absence of the wall surface substrate supporting resin sheet.

- a bottom substrate supporting resin sheet having a shape substantially the same as the surface shape of the bottom raising member.
- This bottom substrate supporting resin sheet is a foamed and oil-absorbing bottom substrate supporting resin. It is preferable that the sheet is arranged so as to form a slight gap.
- the gap formed in this way is in contact with the substrate material to be stored or the bottom of the substrate, and the spacer is also a resin for supporting the bottom substrate. Since the sheet is made of foamed resin and fixed to the bottom raising member that is made of foamed resin, it is difficult to hold the base material and the substrate to be stored tightly.
- the substrate material and the substrate held by the grease sheet can be configured so that the stress is not concentrated on the bottom of the substrate or the like even if the substrate material or the substrate is deformed within the range of flexibility. it can.
- Such a bottom-up member also serves as a very good fall-preventing means for the wall surface base material supporting resin sheet.
- the bottom raising member can be adjusted in the storage depth by forming the bottom raising member of various thicknesses, and the thickness of the bottom raising member can be appropriately selected.
- the depth can be adjusted by the bottom raising member in one type of container, so that substrate materials or substrates of different sizes can be transported stably. it can.

- the substrate can be held and transported.
- the substrate mounting and substrate taking out workability is good.
- the cushion function is exerted in the gap formed between the resin sheet and the inner heat insulating plate, so that the substrate is moved up and down in small increments due to vibration during conveyance, and the force is transmitted to the resin sheet. Even in such a case, the resin sheet can be recessed or deformed to absorb the force. Thereby, the cracking of a board
- the inner heat insulating plate and the resin sheet are all formed separately as a single body such as a hexahedron, it is easy to form and improve the dimensional accuracy. .
- the desiccant in order to obtain a predetermined dimensional accuracy, it is possible to adjust between the inner heat insulating plate and the resin sheet without managing all the dimensional accuracy, and the degree of design freedom can be increased. Further, when the desiccant is accommodated, a tape or the like is not necessary, and if the desiccant is accommodated inside through the slit, the desiccant can be prevented from dropping and damaging the substrate.
- the container body is made of foamed synthetic resin and can protect the impact force of the substrate accommodated against the impact from the outside, and can also prevent the occurrence of condensation due to a temperature difference or the like. If a clearance for the cushion is secured also on the lid side, it is possible to absorb the impact force when it vibrates in the vertical direction as much as possible and further prevent cracking.
- the desiccant when the desiccant is accommodated, a tape or the like is unnecessary, and if the desiccant is accommodated inside through the slit, the desiccant falls. This can prevent the substrate from being damaged.

- a means for preventing the wall surface substrate supporting resin sheet from falling into the container is provided.
- the wall surface substrate supporting resin sheet is disposed on the wall surface with a slight gap therebetween, thereby achieving this capacity. Stress generated by the substrate itself stored in the container can be absorbed by this gap, and the occurrence of damage to the substrate originating from the holding portion of the storage substrate can be significantly reduced. That is, the slight gap formed between the side surface of the container and the wall surface substrate supporting resin sheet functions as a buffer space for internal stress generated by stagnation of the stored substrate itself.
- the wall surface substrate supporting resin sheet disposed on the surface of the container in which the substrate holding groove is formed is not in close contact with the side surface of the container. Since the wall surface supporting resin sheet is prevented from falling, the wall surface supporting resin sheet can be stably held by forming a certain gap with respect to the wall surface.
- a bottom raising member in which a holding groove for the substrate is formed is arranged at the bottom portion that is always in contact with the substrate to be stored.
- the surface of the bottom raising member is arranged.
- the bottom substrate supporting resin sheet having a shape substantially the same as the shape is arranged with a slight gap formed on the surface of the bottom raising member, so that the stagnation generated on the stored substrate etc. The occurrence of deformation can be reduced, and the slight gap formed between the bottom raising member and the bottom substrate supporting resin sheet can act as a buffer space for internal stress generated in the substrate itself. This can significantly reduce the occurrence of damage to the storage board.
- the depth of the storage space in the container can be adjusted in accordance with the substrate to be stored, and further, the inside of the lid can be relaxed in the same manner as described above.
- the substrate can be stored more safely.
- the storage substrate is protected from an impact from the outside because it is formed of the foamed resin.
- the weight of the stored substrate can also absorb the internal stress caused by the stagnation and prevent the substrate from being damaged.
- the wall surface substrate supporting resin sheet or the like is a hexahedron in which an opening is formed.
- the support groove Even if the flexibility is impaired and a gap is formed between the wall surface and the resin sheet for supporting the wall surface substrate, the gap does not function as a buffer gap for the storage substrate. Furthermore, when trying to insert a box into the container body, it is extremely difficult to insert the box, and the work efficiency is very poor. Therefore, in the present invention, basically, the flexibility of the support groove of the resin sheet for supporting a wall surface substrate formed in substantially the same shape as the support groove formed on the wall surface of the container main body is maintained.

- the substrate can be transferred to the substrate.
- the bottom raising member is a very good fall prevention means for the side wall substrate holding resin sheet disposed on the side wall of the container main body. Furthermore, by reducing the excess space in the container, the substrate transport safety is also increased.
- the substrate transport container of the present invention is made of foamed resin, and can protect the storage substrate against the impact of an external force, and may occur due to a temperature difference from the outside. Of course, there can be no dew condensation.

- the container main body 112 and the lid body 145 of the present invention as described above and the bottom raising member 130 are made of foamed resin, and there is no particular limitation on such foamed resin.
- the raw material for forming these resinous foams does not need to be a single foamable resinous material.
- a composition containing a plurality of coffins such as a composition can be used.
- a composition in which a rubber component is blended with polystyrene as described above is supplied as high impact polystyrene.
- the foam obtained by foaming for example, in a mold so as to have an expansion ratio of about 10 to 60 times, preferably about 20 to 50 times,
- characteristics necessary for a substrate transport container such as good impact resistance and heat insulation are exhibited. That is, by forming a container body made of the above-mentioned foamed resin and a lid, the substrate holding container becomes about 0.26 kcalZm.hr. ° C or less, and even when the external temperature changes. It is possible to prevent the temperature in the substrate transport container from changing rapidly.
- a skin layer is formed on the surface of the formed foam, and such a skin layer is in the vicinity of the stop portion in the thickness direction of the foamed resin. It forms a denser layer than the foam in By forming such a skin layer, the surface strength of the foamed resin becomes dust, and the strength of the foam is improved, water resistance and moisture permeability resistance are excellent, and wear resistance is further improved. Improves.
- a skin layer is formed at a depth of about 1 mm from the surface of the foam. Such a skin layer can be formed by contacting the mold and the foamed resin when forming the foamed resin.
- the wall surface substrate supporting resin sheets 122a and 122b, the surface protecting resin sheets 124a and 124b, the bottom substrate supporting resin sheet 128, the lid substrate supporting resin sheet 147, etc. Can be formed from a synthetic resin sheet.
- synthetic resin sheets used here include ⁇ -olefin-resistant sheets such as polyethylene, LLDPE, polypropylene, and polybutylene, and heat such as polystyrene, polyvinyl chloride, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyester, and polyamide. Examples thereof include a sheet made of plastic resin.
- the resin sheet to which the predetermined form as described above is applied adopts such a forming method that is preferably manufactured by various forming methods such as vacuum forming, compression forming, and extrusion forming.
- various additives may be mix
- additives include antistatic agents, conductive fillers, colorants, antioxidants and the like.
- this substrate transport container may store a substrate in which a semiconductor is incorporated.
- the agent and soot or conductive filler include conductive carbon, conductive metal, and conductive surfactant.
- conductive carbon When such an antistatic agent and soot or conductive filler are blended, these components are used in such an amount that they do not leave the resin sheet surface and contaminate the substrate to be stored. It is used in an amount within the range of 0.1 to: LOO parts by weight with respect to 100 parts by weight of the resin component forming the resin sheet.
- this resin sheet usually has a volume resistivity of about 10 3 to 10 12 ⁇ 'cm. Even if a board is mounted on it, its electrical characteristics will not be damaged by static electricity.
- the resin sheet made of such a resin can be formed by, for example, vacuum forming or the like.
- the shape is substantially the same as the surface shape.
- a grease is provided for each wall surface of the container main body.
- the flexibility of the bellows-like sheet surface support groove 126 of the wall surface substrate supporting resin sheet 122a, 22b in which the sheet surface support groove 126 is formed is impaired. Therefore, it is possible to use a resin sheet formed in an L shape as described above. Similarly, the flexibility of the bellows-like sheet surface support groove 126 is not impaired even in a cylindrical resin sheet with no bottom formed, and thus the resin sheet is formed into a rectangular cylinder. May be. Thus, even if the resin sheet is formed in a rectangular tube shape, there is no bottom portion, so that it is not particularly difficult to insert the sheet into the container body.
- the bottom portion is attached to the rectangular tube-like sheet with a force, the low-angle cylindrical sheet-combining box becomes remarkably difficult to insert into the container main body, and the storage substrate has a small space.
- the bellows-like support groove that absorbs the stress is fixed at the edge of the bottom, and the flexibility thereof is impaired. Therefore, the stress is caused by internal stress generated in the substrate itself as in the substrate transfer container of the present invention. Can not reduce the occurrence of substrate damage.
- the substrate transport container of the present invention has the above-described configuration, and the substrate can be safely transported by storing the substrate in the container. That is, the substrate transport container of the present invention is formed of a foamed resin excellent in impact resistance and heat insulation, and the container body portion and the lid are formed, so that the force substrate such as impact of external force and external temperature change is protected. Of course, it can be used for the internal stress generated by the stored substrate (mainly the stress caused by the weight of the substrate). The sheet can be absorbed by the flexibility of the sheet, and the storage board can be stored more safely. Furthermore, the resin sheet disposed inside the substrate transport container of the present invention is not fixed to the corresponding wall surface and is disposed with a slight gap.
- a means for preventing the resin sheet from falling into the inside is formed, and the resin sheet is securely arranged at a predetermined position. Therefore, in a substrate manufacturer or the like that actually uses the substrate transport container of the present invention, The grease sheet is placed exactly in place There is no need to check whether or not. Further, basically, the resin sheet is disposed independently of the wall surface as in the present invention, so that the installation of the resin sheet becomes very simple.
- the depth of the container can be adjusted in accordance with the substrate to be transported, so that an extra space is not formed in the container. Therefore, the substrate can be transported more safely.
- the substrate transport container of the present invention has the above-described configuration, but can be variously modified within a range that does not impair the object of the present invention.
- a gas exchange port may be formed in the substrate transport container of the present invention, and the air in the substrate transport container may be replaced with an inert gas such as nitrogen gas or argon gas.
- an inert gas such as nitrogen gas or argon gas.
- a banding concave portion is formed on the outer peripheral portion of the substrate transporting container of the present invention to improve the sealing performance of the substrate transporting container and to prevent the lid from falling off due to carelessness. Can be easily performed.
- the substrate transport container of the present invention is usually used so that the stored substrate stands up.
- a container is used. It is also possible to mark the container clearly indicating the loading direction.
- the substrate transport container of the present invention can be suitably used when the substrate is moved, but it is needless to say that it can be used not only at the time of movement but also at the time of storage.
