Description

Technical Field

[0001] This application relates to the field of material storage technology, and in particular to a storage device. Background Technology

[0002] In the production and processing process, materials often need to be temporarily stacked for storage. Currently, materials are mostly stacked from bottom to top by manual labor or robotic arms. In this case, the stacking difficulty increases with the stacking height. Furthermore, when materials are needed, they can only be retrieved from top to bottom, which is inconvenient. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a storage device that can improve the convenience of storing and retrieving materials.

[0004] This application provides a storage device for storing and retrieving materials. The storage device includes a carrier, a first movable member, a second movable member, and support members. The carrier has a bearing surface capable of bearing materials. The first movable member is located on at least one side of the carrier along a first direction and can reciprocate along a first direction and a second direction. The first direction is bidirectional and parallel to the bearing surface, and the second direction is bidirectional and perpendicular to the bearing surface. The second movable member is located on at least one side of the carrier along the first direction and can reciprocate along the first direction. At least two support members are spaced apart on the first movable member along the second direction, and at least two support members are spaced apart on the second movable member along the second direction. Along the first direction, the support members protrude from the side of the first and second movable members closest to the carrier.

[0005] By moving the first moving member closer to the carrier member in a first direction so that its support member contacts the material on the carrier member, and then moving it away from the carrier member in a second direction to lift the material, the material can be transferred from the carrier member to the first moving member. Similarly, by moving the second moving member closer to the carrier member in the first direction and the first moving member moving away from the carrier member in the first direction, the material can be transferred from the first moving member to the second moving member. When the first moving member moves closer to the carrier member in the second direction and then closer to the carrier member again in the first direction, its support member can simultaneously support the material on both the carrier member and the second moving member. By moving the second moving member away from the carrier member in the first direction to avoid the first moving member moving away from the carrier member in the second direction, the material can be transferred from the carrier member and the second moving member to the first moving member. By transferring the material again from the first moving member to the second moving member, the material can be alternately supported by the first and second moving members, and can be gradually lifted from the first moving member in the second direction and then stored intermittently on the second moving member, which improves the convenience of material storage. When materials are retrieved, the materials are transferred from the second moving member to the first moving member, and the second moving member moves away from the carrier member in the first direction to avoid the first moving member moving closer to the carrier member in the second direction, which helps to improve the convenience of retrieving materials.

[0006] In one or more of the above embodiments, the first moving members are disposed on opposite sides of the support member along the first direction, and the first moving members on both sides can move towards each other and away from each other along the first direction. The second moving members are disposed on opposite sides of the support member along the first direction, and the second moving members on both sides can move towards each other and away from each other along the first direction. In this case, the support members of both the first and second moving members can provide force-bearing surfaces for supporting materials on opposite sides along the first direction, which is beneficial to improving the supporting capacity of the support members on the first and second moving members for supporting materials.

[0007] In one or more of the above embodiments, the storage device includes a structural component, which includes a base, a first support, and a second support. The first support is movably disposed on the base along a second direction, and the second support is fixedly disposed on the base. A load-bearing member is disposed on the base, a first movable member is disposed on the first support, and a second movable member is disposed on the second support. The first support, movably disposed on the base, facilitates the reciprocating movement of the first movable member along the second direction, while the second support, fixedly disposed on the base, improves the stability of materials stored on the second movable member.

[0008] In one or more of the above embodiments, the storage device includes a cylinder, which includes a cylinder body and a piston rod. The piston rod is disposed on the cylinder body and can reciprocate relative to the cylinder body in a first direction. The cylinder bodies of different cylinders are respectively fixedly mounted on a first support and a second support, and the piston rods of different cylinders are respectively connected to a first moving member and a second moving member. The extension and retraction movement of the piston rod helps to improve the stability of the reciprocating movement of the first moving member and the second moving member in the first direction.

[0009] In one or more of the above embodiments, the storage device includes a guiding assembly, which includes a fixing member and a guide member. The guide member is movably disposed on the fixing member along a first direction. The fixing members of different guiding assemblies are respectively fixedly disposed on the first bracket and the second bracket, and the guide members of different guiding assemblies are respectively connected to the first moving member and the second moving member. Since the material is alternately supported by the first moving member and the second moving member, when the amount of material is large, the piston rod of the cylinder is subjected to a large load. The guiding assembly can distribute the load on the piston rod of the cylinder, thereby reducing the possibility of deformation of the piston rod of the cylinder and further improving the stability of the reciprocating motion of the first moving member and the second moving member along the first direction.

[0010] In one or more of the above embodiments, the storage device includes an airbag that can expand and contract along a second direction. Along the second direction, one end of the airbag is fixedly mounted on the base, and the other end of the airbag is connected to a first support. By inflating or deflating the airbag to expand and contract along the second direction, the first support can reciprocate along the second direction, thereby facilitating the reciprocating movement of the first moving member along the second direction.

[0011] In one or more of the above embodiments, the storage device includes a limiting component, which includes a connector, a first limiting member, and a second limiting member. The first and second limiting members are fixedly disposed on the connector. The base has a through hole extending along a second direction. The connector connects to the first bracket and passes through the through hole. Along the second direction, the first limiting member is located between the first bracket and the base, and the second limiting member is located on the side of the base opposite to the first bracket. The projections of the first and second limiting members cover the projection of the through hole. Through the limiting component, when the first bracket moves closer to the carrier along the second direction, the first limiting member is stopped by the base; when the first bracket moves away from the carrier along the second direction, the second limiting member is stopped by the base. Thus, the cooperation of the first and second limiting members can limit the maximum distance of the reciprocating movement of the first bracket along the second direction, which is beneficial to improving the consistency of the distance the first bracket moves along the second direction.

[0012] In one or more of the above embodiments, at least three support members are spaced apart from the first movable member along the second direction, and at least three support members are spaced apart from the second movable member along the second direction. Along the second direction, the spacing between two adjacent support members is equal. In this case, during the alternating support of the material by the first and second movable members, the possibility of misalignment between the support members of the first and second movable members along the second direction can be reduced, thereby reducing the possibility of material falling and causing deformation or damage, and helping to maintain the integrity of the material.

[0013] In one or more of the above embodiments, the carrier includes a first roller, the rolling plane of which is perpendicular to a first direction. Through the first roller, when the storage device is connected to the feed line or discharge line of the production line equipment, it facilitates the automatic flow of material from the carrier to the feed line, or the automatic flow of material from the discharge line to the carrier, thereby improving the efficiency of storing or retrieving material through the storage device.

[0014] In one or more of the above embodiments, the support member includes a second roller, the rolling plane of which is perpendicular to the bearing surface and parallel to the first direction. Through the second roller, when the first and second moving members move along the first direction to make the support member contact or detach from the material, the process of the support member contacting or detaching from the material is made smoother, thereby reducing wear on the material caused by the support member and helping to maintain the integrity of the material.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] This application provides a storage device for storing and retrieving materials. The storage device includes a carrier, a first movable member, a second movable member, and support members. The carrier has a bearing surface capable of bearing materials. The first movable member is located on at least one side of the carrier along a first direction and can reciprocate along a first direction and a second direction. The first direction is bidirectional and parallel to the bearing surface, and the second direction is bidirectional and perpendicular to the bearing surface. The second movable member is located on at least one side of the carrier along the first direction and can reciprocate along the first direction. At least two support members are spaced apart on the first movable member along the second direction, and at least two support members are spaced apart on the second movable member along the second direction. Along the first direction, the support members protrude from the side of the first and second movable members closest to the carrier.

[0025] In the storage device of this application, by moving a first moving member closer to a carrier member in a first direction so that the support member of the first moving member contacts the material located on the carrier member, and then moving it away from the carrier member in a second direction to lift the material, the material can be transferred from the carrier member to the first moving member. By moving a second moving member closer to the carrier member in the first direction and the first moving member moving it away from the carrier member in the first direction, the material can be transferred from the first moving member to the second moving member. When the first moving member moves closer to the carrier member in the second direction and then moves closer to the carrier member again in the first direction, the support member of the first moving member can simultaneously support the material on the carrier member and the second moving member. By moving the second moving member away from the carrier member in the first direction to avoid the first moving member moving away from the carrier member in the second direction, the material can be transferred from the carrier member and the second moving member to the first moving member. By transferring the material from the first moving member to the second moving member again, the material can be alternately supported by the first moving member and the second moving member, and the material can be gradually lifted by the first moving member in the second direction and then stored intermittently on the second moving member, which improves the convenience of storing materials. When materials are retrieved, the materials are transferred from the second moving member to the first moving member, and the second moving member moves away from the carrier member in the first direction to avoid the first moving member moving closer to the carrier member in the second direction, which helps to improve the convenience of retrieving materials.

[0026] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please see Figures 1 to 3 The first aspect of this application provides a storage device 10 for storing and retrieving materials 20. The materials 20 may be multiple sets of base plates 21 and top covers 22. After retrieving a set of base plates 21 and top covers 22, multiple stacked copper-clad laminates (CCLs) may be sandwiched between the base plates 21 and top covers 22. Of course, the materials 20 may also be other sheet metal parts or non-sheet metal parts.

[0028] Please see Figure 1 The storage device 10 includes a support member 11, which has a support surface for carrying materials 20. When there is only one support member 11, the support surface can be a continuous plane; when there are multiple support members 11, the support surface can be composed of the support areas of multiple support members 11. The multiple support members 11 can be spaced apart to expand the range of the support surface.

[0029] Please see Figure 1The storage device 10 includes a first movable member 12, which is disposed on at least one side of the support member 11 along a first direction X. The first movable member 12 can reciprocate along the first direction X, thereby moving closer to or away from the center of the support member 11 along the first direction X, so that the first movable member 12 can move closer to or away from the material 20 along the first direction X, which is a bidirectional direction and parallel to the support surface. The first movable member 12 can also reciprocate along a second direction Y, thereby moving closer to or away from the support member 11 along the second direction Y, which is a bidirectional direction and perpendicular to the support surface. Please see Figure 1 The storage device 10 includes a second movable member 13, which is disposed on at least one side of the support member 11 along a first direction X. The second movable member 13 can reciprocate along the first direction X, thereby moving the second movable member 13 closer to or away from the center of the support member 11 along the first direction X, so that the second movable member 13 can move closer to or away from the material 20 along the first direction X.

[0030] Please see Figure 1 The storage device 10 includes support members 14. At least two support members 14 are spaced apart from the first movable member 12 along the second direction Y. Along the first direction X, the support members 14 protrude from the side of the first movable member 12 near the bearing member 11, so that when the first movable member 12 approaches the material 20 along the first direction X, the support members 14 of the first movable member 12 can easily contact and support the material 20; and when the first movable member 12 moves away from the material 20 along the first direction X, the support members 14 of the first movable member 12 can easily detach from the material 20. At least two support members 14 are spaced apart from the second movable member 13 along the second direction Y. Along the first direction X, the support members 14 protrude from the side of the second movable member 13 near the bearing member 11, so that when the second movable member 13 approaches the material 20 along the first direction X, the support members 14 of the second movable member 13 can easily contact and support the material 20; and when the second movable member 13 moves away from the material 20 along the first direction X, the support members 14 of the second movable member 13 can easily detach from the material 20. Thus, by having the first moving member 12 and the second moving member 13 alternately move closer to or further away from the material 20 along the first direction X, the material 20 can be easily supported alternately by the first moving member 12 and the second moving member 13.

[0031] The aforementioned method involves the first moving member 12 approaching the carrier member 11 along the first direction X so that its support member 14 contacts the material 20 located on the carrier member 11, and then moving away from the carrier member 11 along the second direction Y to lift the material 20, thereby transferring the material 20 from the carrier member 11 to the first moving member 12. Similarly, the second moving member 13 approaching the carrier member 11 along the first direction X and the first moving member 12 moving away from the carrier member 11 along the first direction X can transfer the material 20 from the first moving member 12 to the second moving member 13. When the first moving member 12 approaches the carrier member 11 along the second direction Y and then approaches the carrier member 11 again along the first direction X, the support member 14 of the first moving member 12 can simultaneously support the material 20 on both the carrier member 11 and the second moving member 13. By moving away from the carrier member 11 along the first direction X to avoid the first moving member 12 moving away from the carrier member 11 along the second direction Y, the material 20 can be transferred from the carrier member 11 and the second moving member 13 to the first moving member 12. By transferring material 20 from the first moving member 12 to the second moving member 13, material 20 can be alternately supported by the first moving member 12 and the second moving member 13. Furthermore, material 20 can be gradually lifted from the first moving member 12 along the second direction Y and then stored intermittently on the second moving member 13, which improves the convenience of storing material 20. When material 20 is retrieved, by transferring material 20 from the second moving member 13 to the first moving member 12, and with the second moving member 13 moving away from the support member 11 along the first direction X to avoid the first moving member 12 approaching the support member 11 along the second direction Y, the convenience of retrieving material 20 is further improved.

[0032] Please see Figure 1 In some embodiments, the carrier 11 includes a first roller 111, the rolling plane of which is perpendicular to the first direction X. Through the first roller 111, when the storage device 10 is connected to the feed line or discharge line of the production line equipment, the material 20 can automatically flow from the carrier 11 to the feed line, or vice versa, which improves the efficiency of storing or retrieving the material 20 through the storage device 10. In some embodiments, the storage device 10 is connected to the feed line or discharge line of the production line equipment along a third direction Z, so that the first moving member 12 and the second moving member 13 can avoid the inflow or outflow of the material 20. The third direction Z is a bidirectional direction and is perpendicular to the first direction X and the second direction Y.

[0033] In some embodiments, there are multiple first rollers 111, and the multiple first rollers 111 are spaced apart along a third direction Z.

[0034] Please see Figure 1In some embodiments, the first movable members 12 are disposed on opposite sides of the support member 11 along the first direction X. The first movable members 12 on both sides can move towards each other and away from each other along the first direction X. Specifically, when the first movable members 12 on both sides move towards each other along the first direction X, the first movable members 12 move closer to the support member 11 along the first direction X; when the first movable members 12 on both sides move away from each other along the first direction X, the first movable members 12 move away from the support member 11 along the first direction X. In this case, the support members 14 of the first movable members 12 can provide a force-bearing surface for supporting the material 20 on opposite sides along the first direction X, which is beneficial to improving the support capacity of the support members 14 on the first movable members 12 for the material 20.

[0035] Please see Figure 1 In some embodiments, the second movable members 13 are disposed on opposite sides of the support member 11 along the first direction X. The second movable members 13 on both sides can move towards each other and away from each other along the first direction X. Specifically, when the second movable members 13 on both sides move towards each other along the first direction X, the second movable members 13 move closer to the support member 11 along the first direction X; when the second movable members 13 on both sides move away from each other along the first direction X, the second movable members 13 move away from the support member 11 along the first direction X. In this case, the support members 14 of the second movable members 13 can provide a force-bearing surface for supporting the material 20 on opposite sides along the first direction X, which is beneficial to improving the support capacity of the support members 14 on the second movable members 13 for the material 20.

[0036] Please see Figure 1 In some embodiments, at least three support members 14 are spaced apart along the second direction Y on the first movable member 12, and at least three support members 14 are spaced apart along the second direction Y on the second movable member 13. Along the second direction Y, the spacing between two adjacent support members 14 is equal. In this case, during the alternating support of the material 20 by the first movable member 12 and the second movable member 13, the possibility of misalignment between the support members 14 of the first movable member 12 and the support members 14 of the second movable member 13 along the second direction Y can be reduced, thereby reducing the possibility of the material 20 falling and causing deformation or damage, and helping to maintain the integrity of the material 20. In some embodiments, along the second direction Y, the lowest support member 14 of the first movable member 12 is lower than the bearing surface of the carrier member 11, and the lowest support member 14 of the second movable member 13 is higher than the bearing surface of the carrier member 11.

[0037] Please see Figure 2In some embodiments, the support member 14 includes a second roller 141, the rolling plane of which is perpendicular to the bearing surface and parallel to the first direction X. Through the second roller 141, when the first moving member 12 and the second moving member 13 move along the first direction X to contact or detach the support member 14 from the material 20, the process of contacting or detaching the support member 14 from the material 20 is made smoother, thereby reducing wear caused by the support member 14 on the material 20 and helping to maintain the integrity of the material 20.

[0038] Please see Figure 1 In some embodiments, the storage device 10 includes a structural component 15, which includes a base 151, a first support 152, and a second support 153. The first support 152 is movably disposed on the base 151 along a second direction Y, and the second support 153 is fixedly disposed on the base 151. A support member 11 is disposed on the base 151, a first moving member 12 is disposed on the first support 152, and a second moving member 13 is disposed on the second support 153. The first support 152, which is movably disposed on the base 151, facilitates the reciprocating movement of the first moving member 12 along the second direction Y, while the second support 153, which is fixedly disposed on the base 151, improves the stability of the material 20 when stored on the second moving member 13.

[0039] Please see Figure 2 In some embodiments, the storage device 10 includes a cylinder 16, which includes a cylinder body 161 and a piston rod 162. The piston rod 162 is disposed on the cylinder body 161 and can reciprocate relative to the cylinder body 161 along a first direction X. The cylinder bodies 161 of different cylinders 16 are respectively fixedly mounted on a first bracket 152 and a second bracket 153, and the piston rods 162 of different cylinders 16 are respectively connected to a first moving member 12 and a second moving member 13. The extension and retraction movement of the piston rod 162 helps to improve the stability of the reciprocating movement of the first moving member 12 and the second moving member 13 along the first direction X. In some embodiments, the cylinder body 161 is connected to an air source, and the piston rod 162 is driven to move by allowing air to enter or exit the cylinder body 161.

[0040] Please see Figure 2In some embodiments, the storage device 10 includes a guide assembly 17, which includes a fixing member 171 and a guide member 172. The guide member 172 is movably disposed on the fixing member 171 along the first direction X. The fixing members 171 of different guide assemblies 17 are respectively fixedly disposed on the first bracket 152 and the second bracket 153, and the guide members 172 of different guide assemblies 17 are connected to the first moving member 12 and the second moving member 13. Since the material 20 is alternately supported by the first moving member 12 and the second moving member 13, when the quantity of material 20 is large, the piston rod 162 of the cylinder 16 is subjected to a large load. The guide assembly 17 can share the load on the piston rod 162 of the cylinder 16, thereby reducing the possibility of deformation of the piston rod 162 of the cylinder 16, which is beneficial to further improve the stability of the reciprocating motion of the first moving member 12 and the second moving member 13 along the first direction X.

[0041] Please see Figure 3 In some embodiments, the storage device 10 includes an airbag 18, which is expandable and contractable along a second direction Y. One end of the airbag 18 is fixedly mounted on the base 151 along the second direction Y, and the other end of the airbag 18 is connected to a first support 152. By inflating or deflating the airbag 18 along the second direction Y, the first support 152 can reciprocate along the second direction Y, thereby facilitating the reciprocating movement of the first moving member 12 along the second direction Y. In some embodiments, the end of the airbag 18 fixed to the base 151 is connected to an air source.

[0042] Please see Figure 3 In some embodiments, the storage device 10 includes a limiting component 19, which includes a connector 191, a first limiting component 192, and a second limiting component 193. The first limiting component 192 and the second limiting component 193 are fixedly disposed on the connector 191. The base 151 has a through hole 1511 extending along the second direction Y. The connector 191 is connected to the first bracket 152 and passes through the through hole 1511. Along the second direction Y, the first limiting component 192 is located between the first bracket 152 and the base 151, and the second limiting component 193 is located on the side of the base 151 opposite to the first bracket 152. The projections of the first limiting component 192 and the second limiting component 193 cover the projection of the through hole 1511. With the limiting component 19, when the first support 152 moves closer to the support member 11 along the second direction Y, the first limiting component 192 is stopped by the base 151. When the first support 152 moves away from the support member 11 along the second direction Y, the second limiting component 193 is stopped by the base 151. Thus, the cooperation of the first limiting component 192 and the second limiting component 193 can limit the maximum distance of the reciprocating movement of the first support 152 along the second direction Y, which is beneficial to improving the consistency of the distance the first support 152 moves along the second direction Y.

[0043] In some embodiments, when the distance between two adjacent support members 14 is equal along the second direction Y, the distance between the first limiting member 192 and the second limiting member 193 along the second direction Y can be adjusted so that the maximum distance of the first bracket 152 reciprocating along the second direction Y is equal to the distance between the two adjacent support members 14. In this way, during the process of the first moving member 12 and the second moving member 13 alternately supporting the material 20, it is beneficial to further reduce the possibility of misalignment of the support members 14 of the first moving member 12 and the support members 14 of the second moving member 13 along the second direction Y.

[0044] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the substantive scope of this application fall within the scope of this application.
