Description

Panel storage container

This disclosure relates to a panel storage container.

Panel storage containers for storing multiple panels are known. For example, Japanese Patent Publication No. 2017-37945 describes a storage container having a container body for storing multiple wafers and a cover for closing the opening of the container body.

In the storage container described in Japanese Patent Publication No. 2017-37945, the lid and the container body are sealed by a sealing member (sealing member). Sometimes, the sealing member that seals the lid and the container body is embedded in a groove provided in the lid to attach the sealing member to the lid. In such a structure, it is desirable to have a structure in which the sealing member is not easily separated from the groove.

This disclosure describes a panel storage container that can more firmly hold a sealing component.

The panel storage container of one aspect of the present disclosure includes: a container body having an opening for storing a plurality of panels; and a cover body for closing the opening. The cover body includes: a cover body having a first surface and a second surface opposite to the first surface, the first surface being a surface opposite to the plurality of panels stored in the container body in a first direction when the cover body closes the opening; and a sealing member disposed on the first surface for sealing between the cover body and the container body. The first surface is provided with a groove recessed in the first direction to hold the sealing member. The groove is defined by a first side wall and a second side wall facing each other in a second direction intersecting the first direction, and a bottom wall connecting the first side wall and the second side wall. The first side wall is provided with a first space connected to the groove, and the sealing member includes a first protrusion disposed in the first space.

In the panel storage container, the sealing member is held in the groove. A first space connected to the groove is provided on the first side wall defining the groove, and the first protrusion of the sealing member is provided in the first space. Thus, even if a force is applied to the sealing member in a direction to cause it to separate from the groove, the first protrusion provided in the first space interferes with the first side wall, so that the sealing member is not easily separated from the groove. As a result, the sealing member can be held more firmly.

The first space may be a through hole. In the above case, even if a force is applied to the sealing member in a direction to cause it to separate from the groove, the sealing member is unlikely to separate from the groove because the first protrusion disposed in the through hole interferes with the first side wall.

The first space may be a recessed portion. In the above case, even if a force is applied to the sealing member in a direction to cause it to separate from the groove, the sealing member is unlikely to separate from the groove because the first protrusion disposed in the recessed portion interferes with the first side wall.

A second space connected to the groove may be provided on the second side wall. The sealing member may include a second protrusion provided in the second space. With the above configuration, when a force is applied to the sealing member in a direction to cause it to separate from the groove, not only the first protrusion provided in the first space will interfere with the first side wall, but also the second protrusion provided in the second space will interfere with the second side wall, so that the sealing member is less likely to separate from the groove. As a result, the sealing member can be held more firmly.

The second space may be a through hole. In the above case, even if a force is applied to the sealing member in a direction to cause it to separate from the groove, the second protrusion provided in the through hole will interfere with the second side wall, so the sealing member is not likely to separate from the groove.

The second space may be a recessed portion. In the above case, even if a force is applied to the sealing member in a direction to cause it to separate from the groove, the second protrusion provided in the recessed portion will interfere with the second side wall, so the sealing member will not easily separate from the groove.

A disassembly hole penetrating the cover body in the first direction may be provided on the bottom wall. With the above-mentioned structure, a force in a direction to disengage the sealing member from the groove can be applied by inserting a rod-shaped member into the disassembly hole. Therefore, the sealing member can be easily disassembled.

According to the present disclosure, the sealing component can be more firmly maintained.

A panel storage container of an embodiment is described with reference to FIG1 . FIG1 is an exploded perspective view of a panel storage container of an embodiment. The panel storage container 1 shown in FIG1 is a container for storing multiple panels. The panel storage container 1 is, for example, in accordance with the Semiconductor Equipment and Materials International (SEMI) standard. As examples of panels, glass substrates for liquid crystal panels and panels equipped with electronic components can be listed. The panel has a rectangular shape. As examples of panel sizes, 510 mm×515 mm and 600 mm×600 mm can be listed. The number of panels that can be stored in the panel storage container 1 is arbitrarily determined, for example, it can be 6, 12, 16, or 24.

The panel storage container 1 is used, for example, in a manufacturing device for manufacturing electronic component assemblies. Electronic component assemblies are manufactured, for example, through the following processes: mounting a plurality of electronic components on a large carrier panel such as a glass plate and a stainless steel plate; sealing these electronic components with epoxy resin or the like; peeling the sealed electronic components from the carrier panel in the form of a panel; and cutting out the electronic components in the form of a panel. The panel storage container 1 is used to transfer the panel between these processes.

The panel storage container 1 includes a container body 2 and a cover 3.

The container body 2 is a rectangular container with an open front (front surface). In other words, the container body 2 is a front open box type container with an opening 2a provided on the front surface. The container body 2 stores a plurality of panels. Specifically, the container body 2 stores a plurality of panels in a state of being stacked with spaces spaced apart from each other in the vertical direction. The panel is taken out of the container body 2 or put into the container body 2 through the opening 2a. The details of the container body 2 will be described below.

The cover 3 is a component used to close the opening 2a of the container body 2. The cover 3 is detachably mounted on the flange 25 defining the opening 2a. The details of the cover 3 will be described below.

The container body 2 and the lid 3 can also be formed by combining a plurality of parts formed of metal materials or resin materials. As an example of the resin contained in the molding material of the resin material, a thermoplastic resin can be cited.

The top plate 21 and the bottom plate 22 face each other in the up-down direction and are arranged substantially in parallel. The pair of side walls 23 face each other in the left-right direction and are arranged substantially in parallel. The back wall 24 connects the rear end of the top plate 21 with the rear end of the bottom plate 22 and the rear end of the pair of side walls 23. The storage space 20 is defined by the top plate 21, the bottom plate 22, the pair of side walls 23 and the back wall 24.

The top plate 21, the bottom plate 22 and the side wall 23 are made of metal materials such as aluminum and stainless steel. The back wall 24 is made of a transparent resin material that allows the storage space 20 to be visually viewed from the outside of the container body 2. A portion of the back wall 24 may also be made of a transparent resin material. Examples of transparent resin materials include acrylic resins, polycarbonates, vinyl chloride resins and cycloolefin polymers.

The flange 25 is a rectangular frame and is provided across the front end of the top plate 21, the front end of the bottom plate 22, and the front end of a pair of side walls 23. The flange 25 defines the opening 2a. The flange 25 is made of, for example, the resin material mentioned above or a metal material such as aluminum and stainless steel. Two upper lock holes 25h are provided in the upper frame portion and the lower frame portion of the flange 25, respectively, and are arranged separately in the left-right direction. The upper lock hole 25h of the upper frame portion and the upper lock hole 25h of the lower frame portion are provided at positions facing each other in the up-down direction.

The frame 26 is used to fix the top plate 21, the bottom plate 22, a pair of side walls 23 and the back wall 24. The frame 26 is made of metal materials such as aluminum and stainless steel. The frame 26 is arranged on the front surface of the back wall 24. The frame 26 has a frame portion 26a (refer to Figure 2), a support 26b (refer to Figure 2), and a pair of supports 26c (refer to Figure 2). The frame portion 26a is a rectangular component and is arranged along the periphery of the back wall 24.

The support 26b and a pair of supports 26c are columnar components extending in the up-down direction. One support 26c, support 26b, and another support 26c are arranged in sequence in the left-right direction and are substantially parallel to each other. The support 26b and a pair of supports 26c extend from the upper frame portion of the frame portion 26a to the lower frame portion. The support 26b is arranged at the center of the frame 26 in the left-right direction, and the pair of supports 26c are arranged near the two ends of the frame 26 in the left-right direction. A plurality of mating holes useful for installing the spindle 61a described later are provided in the support 26b. A plurality of mating holes useful for installing the spindle 62a described later are provided in the support 26c.

The corners of the container body 2 are provided with cover members for preventing particles from invading the storage space 20.

Next, the internal structure of the container body 2 is described with reference to FIG2 . FIG2 is a cross-sectional view along the II-II line of FIG1 . As shown in FIG2 , the panel storage container 1 includes a plurality of supporting members 61, a plurality of supporting members 62, a plurality of side panels 63, and a plurality of retaining bodies 64.

Each supporting member 61 is a portion for supporting the central portion of the panel in the left-right direction. Each supporting member 61 includes a main shaft 61a and a plurality of elastic bodies 61b. The main shaft 61a is a columnar (e.g., cylindrical) member extending in the front-rear direction. The rear end of the main shaft 61a is fixed to a support 26b provided on the inner surface of the back wall 24. The main shaft 61a is, for example, made of a material having high bending rigidity. Examples of the constituent material of the main shaft 61a include metals such as stainless steel and aluminum, and carbon fiber reinforced plastic.

Each elastic body 61b is an annular (for example, a circular ring) component arranged on the outer peripheral surface of the main shaft 61a around the axis of the main shaft 61a. Each elastic body 61b is provided to suppress the sliding of the panel and improve the positioning accuracy of the panel. Each elastic body 61b is made of a rubber material, for example. Examples of rubber materials include EPDM (ethylene propylene diene monomer), silicone rubber, and fluorine rubber. Multiple elastic bodies 61b are arranged at certain intervals along the extension direction of the main shaft 61a.

Each supporting member 62 is a portion for supporting the end portion of the panel in the left-right direction. Each supporting member 62 includes a main shaft 62a, a plurality of elastic bodies 62b, a stopper 62c, and a stopper 62d. The main shaft 62a is a columnar (e.g., cylindrical) member extending in the front-rear direction. The rear end portion of the main shaft 62a is fixed to a support 26c provided on the inner surface of the back wall 24. The main shaft 62a is, for example, made of a material having high bending rigidity. Examples of the constituent material of the main shaft 62a include metals such as stainless steel and aluminum, and carbon fiber reinforced plastic. The length of the main shaft 62a in the front-to-back direction is slightly longer than the length of the panel in the front-to-back direction, and longer than the length of the main shaft 61a in the front-to-back direction.

Each elastic body 62b is an annular (e.g., circular) member disposed on the outer peripheral surface of the main shaft 62a around the axis of the main shaft 62a. Each elastic body 62b is disposed to suppress the sliding of the panel and improve the positioning accuracy of the panel. The constituent materials and arrangement of each elastic body 62b are the same as those of the elastic body 61b, so a detailed description is omitted.

The stopper 62c is a member for preventing the panel from flying out and determining the position of the front end of the panel. The stopper 62c is, for example, made of the resin material described above. The stopper 62c is provided at the front end of the main shaft 62a. The stopper 62d is a member for determining the position of the rear end of the panel. The stopper 62d is, for example, made of the resin material described above. The stopper 62d is provided at the rear end of the main shaft 62a. The stopper 62d has a block shape. The stopper 62d is provided with an insertion hole for the main shaft 62a to be inserted in the front-rear direction.

The number of supporting members 61 and supporting members 62 varies 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 supporting member 61 and two supporting members 62 for each panel. In other words, a storage section for storing one panel is formed by one supporting member 61 and two supporting members 62. One supporting member 61 and two supporting members 62 are arranged in the left-right direction. One supporting member 61 is arranged between two supporting members 62.

Each side plate 63 is a member for installing the retaining body 64. Each side plate 63 is a plate-shaped member extending in the up-down direction. Each side plate 63 is made of metal materials such as aluminum and stainless steel. Each side plate 63 is arranged on the outer surface of the side wall 23. In the present embodiment, two side plates 63 are respectively arranged on each side wall 23. The two side plates 63 are arranged in the front-to-back direction and are substantially parallel to each other. One side plate 63 is arranged near the center of the side wall 23 in the front-to-back direction, and the other side plate 63 is arranged near the front end of the side wall 23 in the front-to-back direction.

Each retaining body 64 is a component used to retain (support) the main shaft 62a and support the end of the panel in the left and right direction. The front end portion of the retaining body 64 is provided with an insertion hole that penetrates the retaining body 64 in the front and rear direction, and the main shaft 62a is inserted through the insertion hole.

The base end of the retaining body 64 abuts against the inner surface of the side wall 23, and the side plate 63, the side wall 23 and the retaining body 64 are positioned by a positioning pin (not shown). In the above state, a screw is inserted from the outer side of the side plate 63 through the insertion hole provided in the side plate 63, and the screw is screwed into the threaded hole provided in the base end of the retaining body 64. In this way, the retaining body 64 is fixed to the side plate 63 while the side wall 23 is clamped by the retaining body 64 and the side plate 63.

Next, the cover body 3 is described in detail with reference to FIG. 1 and FIG. 3 to FIG. 5. FIG. 3 is a three-dimensional view of the cover body shown in FIG. 1 from the back. FIG. 4 is a cross-sectional view along the IV-IV line of FIG. 3. FIG. 5 is a cross-sectional view along the V-V line of FIG. 3. As shown in FIG. 1 and FIG. 3 to FIG. 5, the cover body 3 includes a cover body 31, a cover member 32, a locking mechanism 33 and a sealing member 34.

The cover body 31 is the main body of the cover body 3. The cover body 31 is a rectangular plate. The cover body 31 is made of metal materials such as aluminum and magnesium alloy. The cover body 31 can also be made of thermoplastic resins such as polycarbonate resin. The cover body 31 has a front surface 31a (second surface) and a back surface 31b (first surface). The back surface 31b is the surface facing the multiple panels in the front-to-back direction when the cover body 3 closes the opening 2a. The front surface 31a is the surface on the opposite side of the back surface 31b in the front-to-back direction.

A groove 35 for holding the sealing member 34 is provided on the back surface 31b. In the present embodiment, the groove 35 is provided in an annular shape along the periphery of the back surface 31b and is recessed from the back surface 31b toward the front surface 31a. The groove 35 has a dovetail groove (undercut groove) structure. The groove 35 is defined by a side wall 51 (first side wall), a side wall 52 (second side wall) and a bottom wall 53. The side wall 51 and the side wall 52 (a pair of side walls) face each other in a direction intersecting the front-rear direction. The bottom wall 53 connects the side wall 51 and the side wall 52.

In other words, the bottom wall 53 is provided in an annular shape along the periphery of the back surface 31b, and the side walls 51 and 52 extend from both ends of the bottom wall 53 toward the back surface 31b. The side walls 51 and 52 have an annular shape along the periphery of the back surface 31b, and face each other at a certain distance. The front end 51a of the side wall 51 and the front end 52a of the side wall 52 protrude in a manner that they are close to each other while sandwiching the groove 35.

The side wall 51 is provided with a plurality of through holes 51b (first space). Each through hole 51b is a space connected to the groove 35. Each through hole 51b penetrates the side wall 51 and has a long hole shape extending along the periphery of the back surface 31b. Each through hole 51b is arranged near the center of the length (height) of the side wall 51 in the front-to-back direction. The plurality of through holes 51b are arranged in a ring shape at certain intervals along the periphery of the back surface 31b. That is, a plurality of through holes 51b are respectively provided in the upper part, the lower part, the left part and the right part of the annular side wall 51. Through holes 51b may also be provided at the corners connecting the upper part and the left part, the corners connecting the upper part and the right part, the corners connecting the lower part and the left part, and the corners connecting the lower part and the right part.

The cover member 32 is a member that covers the front surface 31a of the cover body 31. The cover member 32 is a rectangular plate. The cover member 32 is made of a resin material such as polycarbonate. A key hole 32h is provided in the cover member 32. A key not shown is inserted into the key hole 32h.

The locking mechanism 33 locks or unlocks the cover 3 by operating the key inserted into the key hole 32h. The locking mechanism 33 includes a latch (not shown). When the cover 3 is mounted on the flange 25, the latch is inserted into the latch hole 25h provided on the flange 25 by operating the key, thereby locking the cover 3. When the cover 3 is locked, the latch is pulled out from the latch hole 25h by operating the key, thereby unlocking the cover 3.

The sealing member 34 is a member between the sealed container body 2 and the lid body 31. The sealing member 34 is a rope-shaped elastic member. In this embodiment, the sealing member 34 is arranged in a rectangular ring shape. The sealing member 34 is composed of an elastically deformable resin. Examples of the resin include fluororubber, EPDM (ethylene propylene diene monomer rubber), silicone, and urethane. In this embodiment, a rubber sponge is used as the sealing member 34.

The sealing member 34 is provided on the back side 31b of the cover body 31. Specifically, the sealing member 34 is embedded in the groove 35. The sealing member 34 has a volume larger than the volume of the groove 35. The sealing member 34 includes a protrusion 34a and a protrusion 34b (first protrusion).

The protrusion 34a is a portion protruding from the front end 51a and the front end 52a to the outside of the groove 35. The front end surface of the protrusion 34a functions as a sealing surface. Specifically, the front end surface of the protrusion 34a is pressed against the step surface 25a of the flange 25, and the opening 2a of the container body 2 is sealed airtightly. The protrusion 34b is a portion that enters the through hole 51b. The through hole 51b is sealed airtightly by the protrusion 34b entering the through hole 51b. Therefore, the cleanliness of the storage space 20 is maintained.

In the manufacturing process of the panel storage container 1, the sealing member 34 is embedded in the groove 35. As described above, the volume of the sealing member 34 is larger than the volume of the groove 35, and the sealing member 34 can be elastically deformed. Therefore, when the sealing member 34 is embedded in the groove 35, due to the elastic force (restoring force) of the sealing member 34, a part of the sealing member 34 protrudes from between the front end 51a and the front end 52a to form a protrusion 34a, and another part of the sealing member 34 enters the through hole 51b to form a protrusion 34b.

In the panel storage container 1 described above, the sealing member 34 is held in the groove 35. On the side wall 51 of the groove 35, a through hole 51b connected to the groove 35 is provided, and the protrusion 34b of the sealing member 34 is provided in the through hole 51b. The through hole 51b extends in a direction intersecting with the direction (front direction) in which the groove 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction (rear direction) of separation from the groove 35, the protrusion 34b provided in the through hole 51b interferes with the side wall 51, so the sealing member 34 is not easy to separate from the groove 35. As a result, the sealing member 34 can be held more firmly.

In the manufacturing process of the panel storage container 1, a through hole 51b is formed on the side wall 51 from the outer peripheral surface of the side wall 51 toward the groove 35. Therefore, the through hole 51b can be formed more easily than when a recess is formed on the inner peripheral surface of the side wall 51.

In addition, the panel storage container disclosed in the present invention is not limited to the above-mentioned implementation form.

The connection method of each component of the container body 2 may be different from the above-mentioned embodiment. In the above-mentioned embodiment, the container body is formed by combining multiple parts, but it can also be an integral molded product.

The number, size and arrangement of the through holes 51b provided on the side wall 51 can be arbitrarily determined. The number of the through holes 51b provided on the side wall 51 can be 1 or more than 2.

As shown in FIG. 6 (a), a plurality of recesses 51c (first spaces) may be provided on the side wall 51 instead of the plurality of through holes 51b. Each recess 51c is a space connected to the groove 35. Each recess 51c is recessed in a direction away from the side wall 52. The number, size, and configuration of the recesses 51c provided on the side wall 51 are the same as those of the through holes 51b, so their description is omitted. In addition, a ring-shaped recess 51c may be provided around the entire periphery of the side wall 51.

In this modification, a recess 51c connected to the groove 35 is provided on the side wall 51 of the groove 35, and the protrusion 34b of the sealing member 34 is provided in the recess 51c. The recess 51c extends in a direction intersecting with the direction (front direction) in which the groove 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction (rear direction) of separation from the groove 35, the protrusion 34b provided in the recess 51c interferes with the side wall 51, so the sealing member 34 is not easy to separate from the groove 35. As a result, the sealing member 34 can be held more firmly.

As shown in (b) of FIG. 6 , a plurality of recesses 52b (second spaces) may be provided on the side wall 52. Each recess 52b is a space connected to the groove 35. Each recess 52b is recessed in a direction away from the side wall 51. Each recess 52b is provided near the center of the length (height) of the side wall 52 in the front-rear direction. A plurality of recesses 52b are arranged in a ring shape at certain intervals along the periphery of the back surface 31b. That is, a plurality of recesses 52b are provided in each of the upper part, the lower part, the left part, and the right part of the annular side wall 52. Recesses 52b may also be provided at the corners connecting the upper part and the left part, the corners connecting the upper part and the right part, the corners connecting the lower part and the left part, and the corners connecting the lower part and the right part.

The recess 52b can be provided at a position opposite to the through hole 51b or at a position different from the position opposite to the through hole 51b. The number, size and configuration of the recesses 52b provided on the side wall 52 can be determined arbitrarily. The number of recesses 52b provided on the side wall 52 can be one or more than two. An annular recess 52b can also be provided around the entire periphery of the side wall 52.

In this modification, the sealing member 34 further includes a protrusion 34c (second protrusion). The protrusion 34c is a portion that enters the recess 52b.

In the manufacturing process of the panel storage container 1 including the cover 3 of this modification, when the sealing member 34 is embedded in the groove 35, due to the elastic force (restoring force) of the sealing member 34, a part of the sealing member 34 protrudes from between the tip end 51a and the tip end 52a to form a protrusion 34a, another part of the sealing member 34 enters the through hole 51b to form a protrusion 34b, and another part of the sealing member 34 enters the recess 52b to form a protrusion 34c.

In this modification, a through hole 51b connected to the groove 35 is provided on the side wall 51, and a recess 52b connected to the groove 35 is provided on the side wall 52. The protrusion 34b of the sealing member 34 is provided in the through hole 51b, and the protrusion 34c of the sealing member 34 is provided in the recess 52b. The through hole 51b and the recess 52b extend in a direction intersecting with the direction (front direction) in which the groove 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction of separation from the groove 35 (rearward direction), the protrusion 34b provided in the through hole 51b interferes with the side wall 51, and the protrusion 34c provided in the recess 52b interferes with the side wall 52, so that the sealing member 34 is more difficult to separate from the groove 35. As a result, the sealing member 34 can be held more firmly.

Furthermore, when the recess 52b is provided at a position opposite to the through hole 51b, the recess 52b is formed on the side wall 52 while the through hole 51b is formed on the side wall 51 from the outer peripheral surface of the side wall 51 toward the groove 35. Therefore, the through hole 51b and the recess 52b can be easily formed.

As shown in FIG. 6(c), in the variation shown in FIG. 6(a), the side wall 52 may be provided with a plurality of recesses 52b (second spaces). In this case, the sealing member 34 includes a protrusion 34c that enters the recess 52b.

As shown in FIG. 7 , the side wall 52 may be provided with a plurality of through holes 52c (second space). Each through hole 52c is a space connected to the groove 35. Each through hole 52c penetrates the side wall 52. The number, size and configuration of the through holes 52c are the same as those of the recess 52b, so their description is omitted. In this variant, the sealing member 34 also includes a protrusion 34c that enters the through hole 52c.

In this modification, a through hole 51b connected to the groove 35 is provided in the side wall 51, and a through hole 52c connected to the groove 35 is provided in the side wall 52. The protrusion 34b of the sealing member 34 is provided in the through hole 51b, and the protrusion 34c of the sealing member 34 is provided in the through hole 52c. The through hole 51b and the through hole 52c extend in a direction intersecting with the direction (front direction) in which the groove 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction of separation from the groove 35 (rear direction), the protrusion 34b provided in the through hole 51b will interfere with the side wall 51, and the protrusion 34c provided in the through hole 52c will interfere with the side wall 52, so the sealing member 34 is more difficult to separate from the groove 35. As a result, the sealing member 34 can be held more firmly.

The side wall 51 may not be provided with the through hole 51b and the recess 51c, but the recess 52b (first space) or the through hole 52c (first space) may be provided on the side wall 52 (first side wall). In other words, it is sufficient to provide a through hole or a recess on at least one of the side walls 51 and 52.

As shown in FIG8 , a disassembly hole 53h that passes through the cover body 31 (bottom wall 53) in the front-rear direction can be provided on the bottom wall 53. With the above configuration, a rod-shaped member can be inserted into the disassembly hole 53h, thereby applying a force to the sealing member 34 in the direction of separation from the groove 35. Therefore, the sealing member 34 can be easily disassembled.
