Summary of the Invention

Problems to be Solved by the Invention

[0004] In the panel storage container described in Patent Document 1, only the rear end portion of the shaft is fixed to a support provided in front of the rear wall of the container body. Therefore, when the panel storage container is transported, the shaft may sway due to vibration. Due to the sway of the shaft, the panel may be damaged.

[0005] The present disclosure describes a panel storage container capable of reducing the possibility of panel damage.

Means for Solving the Problems

[0006] A panel storage container relating to one aspect of this disclosure comprises a container body defining an internal space for storing a plurality of panels, and a support mechanism provided in the internal space for supporting the plurality of panels. The support mechanism comprises a shaft extending in the front-rear direction and supporting one of the plurality of panels, the rear end of which is fixed to the container body, and a vibration suppression member provided at the front end of the shaft for suppressing vibration of the shaft.

[0007] In this panel storage container, a vibration-damping member is provided at the front end of a shaft whose rear end is fixed to the container body. As a result, vibration of the shaft is suppressed, which reduces the possibility of damage to the panels.

[0008] The vibration damping member may include a weight, a pair of elastic members that clamp the weight vertically, and a case attached to the front end of the shaft that houses the weight and the pair of elastic members, such that each of the pair of elastic members can extend and contract vertically. In this case, an inertial force acts on the weight in the opposite direction to the direction of movement (direction of acceleration) of the case, which moves together with the front end of the shaft. As a result, the vibration damping member functions as a dynamic vibration absorber that absorbs the vibration energy of the shaft. Therefore, since the vibration of the shaft is suppressed, the possibility of damage to the panel can be reduced.

[0009] The case may include a guide section that guides the vertical movement of the weight. In this case, the weight moves more easily in the vertical direction. Therefore, when an inertial force acts on the weight, the possibility of the inertial force being dispersed in directions other than vertical is reduced. Thus, the vibrational energy of the shaft can be absorbed effectively.

[0010] The vibration damping member may be a single weight. In this case, the structure of the vibration damping member can be simplified, and the manufacturing of the vibration damping member can be simplified.

[0011] The support mechanism may further include an elastic body provided on the outer circumferential surface of the shaft around its axis. The upper surface of the vibration damping member may be positioned at the same height as or lower than the upper edge of the elastic body. In this case, the possibility of interference between the vibration damping member and the panel being loaded onto or unloaded from the shaft is reduced. Therefore, the possibility of damage to the panel can be further reduced.

[0012] The upper surface may be a curved surface that is convex upwards in the center in the left-right direction. In this case, even if the panel flexes, the vibration damping member can suppress the localized force applied to the panel. Therefore, the possibility of damage to the panel can be further reduced.

[0013] The vibration-damping member may have a vertically symmetrical shape. In this case, the weight of the upper and lower halves, obtained by dividing the vibration-damping member along the vertical plane of symmetry, can be made uniform when the vibration-damping member is stationary. This allows for a stable vibration-damping effect to be obtained.

[0014] The vibration damping member may be installed within a range of 25 mm in the left-right direction from the center of the container body. In this case, it is possible to reduce the possibility of panel damage while complying with SEMI (Semiconductor Equipment and Materials International) standards. [Effects of the Invention]

[0017] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted. An XYZ coordinate system is shown in each figure. The Y-axis direction is a direction that intersects (here, is orthogonal) the X-axis direction and the Z-axis direction. The Z-axis direction is a direction that intersects (here, is orthogonal) the X-axis direction and the Y-axis direction. As an example, the X-axis direction is the left-right direction (width direction), the Y-axis direction is the front-back direction (depth direction), and the Z-axis direction is the up-down direction (height direction). For convenience of explanation, the terms “front”, “rear”, “upper”, “lower”, “left”, and “right” are used, but are not limited to these directions.

[0018] Referring to FIG. 1, a panel storage container according to an embodiment will be described. FIG. 1 is an exploded perspective view of a panel storage container according to an embodiment. The panel storage container 1 shown in FIG. 1 is a container for storing a plurality of panels. The panel storage container 1 complies with, for example, the SEMI standard. The panel storage container 1 is, for example, referred to as a FOUP (Front Opening Unified Pod) and is used for transferring panels in a factory. Examples of panels include a glass substrate for a liquid crystal panel and a panel on which electronic components are mounted. The panel has a rectangular shape. Examples of the panel size include 510 mm × 515 mm and 600 mm × 600 mm. The number of panels that can be stored in the panel storage container 1 is arbitrarily determined, and may be, for example, 6, 12, 16, or 24.

[0019] The panel storage container 1 includes a container body 2, a lid body 3, and a pair of handles 4.

[0020] The container body 2 is a rectangular parallelepiped container with an open front (front face). In other words, the container body 2 is a front-open box-type container provided with an opening 2a on the front face. The container body 2 defines an internal space for storing a plurality of panels. The container body 2 stores the plurality of panels in a state of being stacked with a gap therebetween in the vertical direction. The panels are inserted into and removed from the container body 2 through the opening 2a.

[0021] The container body 2 includes a top plate 21, a bottom plate 22, a pair of side walls 23, a rear wall 24, and a flange 25.

[0022] The top plate 21, the bottom plate 22, the side walls 23, and the rear wall 24 are rectangular plate materials. The top plate 21 and the bottom plate 22 face each other in the vertical direction and are arranged substantially parallel to each other. The pair of side walls 23 face each other in the left-right direction and are arranged substantially parallel to each other. The rear wall 24 is located at the rear of the container body 2 and faces the lid body 3 in the front-rear direction when the lid body 3 closes the opening 2a.

[0023] Two adjacent members among the top plate 21, the bottom plate 22, the side walls 23, and the rear wall 24 are connected by fastening members such as screws. The top plate 21, the bottom plate 22, the pair of side walls 23, and the rear wall 24 define an internal space for storing a plurality of panels. The top plate 21, the bottom plate 22, and the side walls 23 are made of a metal material such as aluminum and stainless steel, for example.

[0024] The flange 25 is a rectangular frame that extends across the front end of the top plate 21, the front end of the bottom plate 22, and the front ends of the pair of side walls 23. The flange 25 defines the opening 2a. The flange 25 is made of, for example, a resin material or a metal material such as aluminum and stainless steel. The upper and lower frame portions of the flange 25 are each provided with two locking holes 25h that are spaced apart in the left-right direction. The locking holes 25h of the upper frame portion and the locking holes 25h of the lower frame portion are positioned opposite each other in the vertical direction.

[0025] The lid 3 is a component for closing the opening 2a of the container body 2. The lid 3 airtightly closes the opening 2a of the container body 2 via a sealing member such as a gasket. The lid 3 is detachably attached to the flange 25 that defines the opening 2a. When the opening 2a is closed, the lid 3 faces the panel housed in the container body 2 in the front-to-back direction. The lid 3 includes a lid body 31, a cover member 32, and a locking mechanism 33.

[0026] The lid body 31 is the main body portion of the lid 3. The lid body 31 is a rectangular plate material. The lid body 31 is made of a metal material such as an aluminum and magnesium alloy. The lid body 31 may also be made of a thermoplastic resin such as polycarbonate resin. The cover member 32 is a member that covers the front surface of the lid body 31. The cover member 32 is a rectangular plate material. The cover member 32 is made of a resin material such as polycarbonate. The cover member 32 is provided with a keyhole 32h. A key (not shown) is inserted into the keyhole 32h.

[0027] The locking mechanism 33 locks or unlocks the lid 3 by operating a key inserted into the keyhole 32h. The locking mechanism 33 includes a latch (not shown). With the lid 3 attached to the flange 25, the lid 3 is locked when the latch is fitted into the locking hole 25h provided in the flange 25 by operating the key. With the lid 3 locked, the lid 3 is unlocked when the latch is pulled out of the locking hole 25h by operating the key.

[0028] The pair of handles 4 are transport components used by the transport device when transporting the panel storage container 1. The handles 4 are also called robotic flanges (top flanges). The transport device can lift and transport the panel storage container 1 using the pair of handles 4.

[0029] The container body 2, lid 3, and handle 4 are constructed by combining multiple parts molded from metal or resin materials. Examples of resins included in the molding material for resin materials include thermoplastic resins. Examples of thermoplastic resins include polycarbonate, cycloolefin polymers, polyetherimide, polyether ketone, polyether ether ketone, polybutylene terephthalate, polyacetal, liquid crystal polymers, acrylic resins such as polymethyl methacrylate, and acrylonitrile butadiene styrene copolymers. Alloys of these may be used as resins included in the molding material for resin materials.

[0030] These resins may contain conductive materials and various antistatic agents. Conductive materials may include, for example, carbon fibers, carbon powder, carbon nanotubes, or conductive polymers. Antistatic agents such as anionic, cationic, and nonionic types may be used. Benzotriazole, salicylate, cyanoacrylate, oxalic acid anilide, and hindered amine-based ultraviolet absorbers may also be added. Glass fibers or carbon fibers may also be selectively added to improve rigidity.

[0031] As shown in Figure 1, the panel storage container 1 further includes a support mechanism 6. The support mechanism 6 is a mechanism for supporting multiple panels. The support mechanism 6 is provided inside the container body 2 (internal space). The support mechanism 6 includes multiple support members 61, multiple support members 62, and multiple holders 63.

[0032] Each support member 61 is a part that supports the central part of the panel in the left-right direction. Details of the support members 61 will be described later.

[0033] Each support member 62 is a part that supports the left-right end of the panel. Each support member 62 includes a columnar (e.g., cylindrical) shaft extending in the front-rear direction, and a plurality of annular (e.g., circular) elastic bodies provided on the outer surface of the shaft around its axis. The rear end of the shaft is fixed to a support column provided on the inner surface of the back wall 24. The shaft is made of a material with high bending rigidity, for example. Examples of materials used to construct the shaft include metals such as stainless steel and aluminum, and carbon fiber reinforced plastics.

[0034] Each elastic body is provided to suppress panel slippage and improve panel positioning accuracy. Each elastic body is made of, for example, rubber. Examples of rubber materials include EPDM (ethylene propylene diene rubber), silicone rubber, and fluororubber. Multiple elastic bodies are arranged at substantially constant intervals in the direction of extension of the shaft.

[0035] The number of support members 61 and 62 is changed according to the number of panels that can be stored in the panel storage container 1. In this embodiment, the panel storage container 1 includes one support member 61 and two support members 62 for each panel. In other words, one support member 61 and two support members 62 form a storage tier for storing one panel. In the left-right direction, one support member 61 is positioned between two support members 62.

[0036] Each retainer 63 is a member that holds (supports) the shaft of the support member 62 and also supports the left and right ends of the panel. The tip portion of the retainer 63 is provided with an insertion hole that penetrates the retainer 63 in the front-to-back direction, and the shaft of the support member 62 is inserted through the insertion hole. The base portion of the retainer 63 is fixed to the inner surface of the side wall 23.

[0037] Next, the configuration of the support member 61 will be described in detail with reference to Figures 2 to 5. Figure 2 is an enlarged perspective view of the support member shown in Figure 1. Figure 3 is an exploded perspective view of the vibration suppression member shown in Figure 2. Figure 4 is a cross-sectional view along the line IV-IV in Figure 2. Figure 5 is a cross-sectional view along the line VV in Figure 2.

[0038] As shown in Figure 2, each support member 61 includes a shaft 61a, a plurality of elastic bodies 61b, and a vibration damping member 61c. The shaft 61a is a columnar (e.g., cylindrical) member that extends in the front-rear direction and supports one of the plurality of panels. The rear end of the shaft 61a is fixed to the container body 2. Specifically, the rear end of the shaft 61a is fixed to a support column provided on the inner surface of the rear wall 24. The shaft 61a is made of a material with high bending rigidity, for example. Examples of materials used to construct the shaft 61a include metals such as stainless steel and aluminum, and carbon fiber reinforced plastic. The length of the shaft 61a in the front-rear direction is shorter than the length of the panel in the front-rear direction, and shorter than the length of the shaft of the support member 62 in the front-rear direction.

[0039] Each elastic body 61b is an annular (e.g., circular) member provided on the outer circumferential surface of the shaft 61a around its axis. The elastic bodies 61b are provided to suppress panel slippage and improve the positioning accuracy of the panels. The elastic bodies 61b are made of, for example, rubber. Examples of rubber materials include EPDM (ethylene propylene diene rubber), silicone rubber, and fluororubber. Multiple elastic bodies 61b are arranged at substantially constant intervals in the extending direction of the shaft 61a.

[0040] The vibration-dampening member 61c is a member that suppresses vibration of the shaft 61a. The vibration-dampening member 61c is provided at the front end of the shaft 61a. The vibration-dampening member 61c is located within a range of 25 mm in the left-right direction from the center of the container body 2 in the left-right direction. In this embodiment, the axis of each shaft 61a is located at the center of the container body 2 in the left-right direction. Therefore, the length (width) of the vibration-dampening member 61c in the left-right direction is 50 mm or less. The vibration-dampening member 61c has, for example, a vertically symmetrical shape. As shown in Figures 2 to 5, the vibration-dampening member 61c includes a case 70, a weight 73, and a pair of elastic members 74.

[0041] The case 70 is attached to the front end of the shaft 61a and houses the weight 73 and a pair of elastic members 74 so that each elastic member 74 can extend and retract in the vertical direction. The case 70 has a flattened cylindrical shape (for example, a cylindrical shape). The case 70 may be made of a metal material such as aluminum, or a resin material such as polycarbonate. The case 70 includes a cylindrical (box-shaped) case body 71 with an open top end, and a lid member 72 that closes the opening at the top end of the case body 71.

[0042] The lid member 72 is coupled to the upper end of the case body 71 so as to close the opening of the case body 71. Examples of methods for coupling the case body 71 and the lid member 72 include adhesive bonding, welding, press-fitting, fastening with screws, and snap-in fastening. The upper surface of the lid member 72 forms the upper surface 70a of the case 70, and the lower surface of the case body 71 forms the lower surface 70b of the case 70. The upper surface 70a is located at the same height as or lower than the upper edge of the elastic body 61b. The lower surface 70b is located at the same height as or higher than the lower edge of the elastic body 61b. In other words, the vibration damping member 61c does not protrude above or below the elastic body 61b.

[0043] The case body 71 includes a housing section 71a, a mounting section 71b, and a guide section 71c. The housing section 71a defines a housing space for housing the weight 73 and a pair of elastic members 74. The mounting section 71b is a part for attaching to the front end of the shaft 61a. The mounting section 71b has a tubular shape with one end open. The front end of the shaft 61a is inserted into and connected to the mounting section 71b. Examples of methods for connecting the front end of the shaft 61a and the mounting section 71b include fastening with screws, press-fitting, and bonding. In this embodiment, the inner diameter of the mounting section 71b is slightly smaller than the outer diameter of the shaft 61a, and the front end of the shaft 61a is connected to the mounting section 71b by press-fitting the front end of the shaft 61a into the mounting section 71b.

[0044] The guide portion 71c is a part that guides the vertical movement of the weight 73. The guide portion 71c is provided on the inner circumferential surface of the housing portion 71a and extends in the vertical direction. In this embodiment, the case body 71 includes three guide portions 71c. The three guide portions 71c are arranged at substantially equal intervals in the circumferential direction of the inner circumferential surface of the housing portion 71a so as to surround the weight 73. The position of the weight 73 in the front-to-back and left-to-right directions is determined by the three guide portions 71c.

[0045] The weight 73 is provided within the housing portion 71a of the case body 71 so as to be movable in the vertical direction. The weight 73 has a flat plate shape (for example, a disc shape) that is slightly smaller than the inner circumferential surface of the housing portion 71a. The weight 73 is sandwiched between a pair of elastic members 74 in the vertical direction and is not fixed to the case 70. The weight 73 may be made of a metallic material such as stainless steel, copper, bronze, brass, and tungsten, or it may be made of a resin material such as polycarbonate and polyacetal. The weight of the weight 73 is appropriately determined by experimentation or other means to a weight that can effectively suppress the vibration of the shaft 61a. The weight of the weight 73 is determined, for example, according to the length of the shaft 61a.

[0046] Each elastic member 74 is configured to be expandable and contractible in the vertical direction. Each elastic member 74 may be made of an elastically deformable material such as gel or rubber, or it may be a spring. Examples of springs include leaf springs, compression coils, and air springs. The spring may be made of a metal material or a resin material.

[0047] After the lower elastic member 74, the weight 73, and the upper elastic member 74 are stacked in order within the housing section 71a, the lid member 72 is connected to the case body 71 so as to sandwich the pair of elastic members 74 in the vertical direction. This creates the vibration suppression member 61c.

[0048] Next, the principle of vibration suppression of the shaft 61a by the vibration suppression member 61c will be explained. Since the rear end of the shaft 61a is fixed to the container body 2, the front end of the shaft 61a vibrates vertically due to vibrations such as those that occur when transporting the panel storage container 1. At this time, the vibration suppression member 61c (case 70) also moves vertically along with the front end of the shaft 61a. In the vibration suppression member 61c, the weight 73 is housed in the case 70 via a pair of elastic members 74 that sandwich the weight 73 vertically, so an inertial force acts on the weight 73 in the opposite direction to the direction of movement (direction of acceleration) of the case 70. As a result, the vibration suppression member 61c functions as a dynamic vibration absorber that absorbs the vibration energy of the shaft 61a. Consequently, the time it takes for the vibration of the shaft 61a to subside can be shortened.

[0049] In the panel storage container 1 described above, a vibration suppression member 61c is provided at the front end of a shaft 61a whose rear end is fixed to the container body 2. Therefore, vibration of the shaft 61a is suppressed, which reduces the possibility of damage to the panels.

[0050] In the vibration-dampening member 61c, the weight 73 and the pair of elastic members 74 are housed in the case 70 such that each of the pair of elastic members 74 that clamp the weight 73 in the vertical direction can extend and retract in the vertical direction. With this configuration, when the shaft 61a vibrates in the vertical direction, an inertial force acts on the weight 73 in the opposite direction to the direction of movement (direction of acceleration) of the case 70, which moves together with the front end of the shaft 61a. As a result, the vibration-dampening member 61c functions as a dynamic vibration absorber that absorbs the vibration energy of the shaft 61a. Therefore, since the vibration of the shaft 61a is suppressed, the possibility of damage to the panel can be reduced.

[0051] The guide section 71c guides the vertical movement of the weight 73. This configuration makes it easier for the weight 73 to move vertically, and suppresses displacement of the weight 73 in the front-to-back and left-to-right directions. Therefore, when an inertial force acts on the weight 73, the possibility of the inertial force being dispersed in directions other than vertical is reduced. Consequently, the vibration energy of the shaft 61a can be effectively absorbed, and the time it takes for the vibration of the shaft 61a to subside can be further shortened.

[0052] The panels are supported by multiple elastic bodies contained within one support member 61 and two support members 62 that form the storage tiers. In the panel storage container 1, the upper surface 70a of the vibration damping member 61c is positioned at the same height as or lower than the upper edge of the elastic body 61b. This configuration reduces the possibility of interference between the panels being loaded into or unloaded from the storage tiers and the vibration damping member 61c. Therefore, the possibility of damage to the panels can be further reduced.

[0053] The vibration-dampening member 61c has a vertically symmetrical shape. Therefore, the weight of the upper and lower halves obtained by dividing the vibration-dampening member 61c along the vertical plane of symmetry can be made uniform when the vibration-dampening member 61c is at rest. This allows for a stable vibration-dampening effect to be obtained.

[0054] The vibration damping member 61c is provided within a range of 25 mm in the left-right direction from the center of the container body 2. This makes it possible to reduce the possibility of panel damage while complying with SEMI standards.

[0055] The panel storage container relating to this disclosure is not limited to the embodiments described above.

[0056] The case body 71 does not necessarily have to include the guide portion 71c.

[0057] The upper surface 70a may be positioned higher than the upper edge of the elastic body 61b, provided that it does not interfere with the panel that is inserted into or removed from the storage stage formed by the support member 61 including the vibration-damping member 61c. In other words, the vibration-damping member 61c may protrude above the elastic body 61b. The lower surface 70b may be positioned lower than the lower edge of the elastic body 61b, provided that it does not interfere with the panel that is inserted into or removed from the storage stage one level below the storage stage formed by the support member 61 including the vibration-damping member 61c. In other words, the vibration-damping member 61c may protrude below the elastic body 61b.

[0058] The vibration-damping member 61c may be a single weight. In this case, even if the shaft 61a vibrates vertically, the weight will try to stay in place due to the law of inertia, and the vibration of the shaft 61a can be suppressed by the inertial resistance of the weight. Therefore, the possibility of damage to the panel can be reduced. Furthermore, this configuration allows for a simplification of the structure of the vibration-damping member 61c, and simplifies the manufacturing of the vibration-damping member 61c.

[0059] As shown in Figure 6, the upper surface 70a may be a curved surface that is convex upward in the center in the left-right direction. For example, if the vibration damping member 61c has a rectangular shape when viewed from the front, when the panel flexes, localized force is applied to the panel at the upper left and right corners of the case 70, which may damage the panel. In contrast, with the above configuration, even if the panel flexes, the lower surface of the panel extends along the upper surface 70a of the vibration damping member 61c. Therefore, it is possible to suppress the application of localized force to the panel by the vibration damping member 61c. Thus, it is possible to further reduce the possibility of damage to the panel.

[0060] The lower surface 70b may be a curved surface that is convex downwards in the center in the left-right direction. In other words, the vibration-dampening member 61c has a shape in which the left and right ends are thinner than the center in the left-right direction when viewed from the front. In this case, the vibration-dampening member 61c has a substantially vertically symmetrical shape. Therefore, the weight of the upper half and the lower half obtained by dividing the vibration-dampening member 61c with a plane of symmetry in the vertical direction can be made uniform when the vibration-dampening member 61c is at rest. This makes it possible to obtain a stable vibration-dampening effect while suppressing localized force applied to the panel by the vibration-dampening member 61c.
