[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0026] See also Figure 1-3 As shown, in some embodiments, the present application provides a retractable shelf, which includes a frame body 10, a pallet 11 and a driving mechanism 12. The frame body 10 includes a shielding layer 14 and a storage layer 15 located below the shielding layer 14. The storage layer 15 is provided with a slide rail 13 extending along a first direction, and the first direction is the width direction of the storage layer 15. The pallet 11 is slidably installed on the slide rail 13 through a slider. At least one storage position for placing goods is provided on the pallet 11. The driving mechanism 12 is used to drive the pallet 11 to move along the slide rail 13 to move the storage position out of the storage layer 15.
[0027] The present application intends to slide a cargo pallet 11 on a storage layer 15. When placing or taking goods on the storage space of the cargo pallet 11, the cargo pallet 11 can slide toward the outside of the storage layer 15 along the slide rail 13 in advance so that the storage space slides out of the storage layer 15, thereby preventing manual labor or handling devices (such as grippers) from being affected by the height of the storage layer 15 when loading and unloading goods on the storage space, thereby improving the adaptability of the retractable shelf and the utilization rate of the storage space.
[0028] It should be noted that the shielding layer 14 in the present application is located at the top of the retractable shelf. The shielding layer 14 can be a top cover structure used only for shielding, or it can be a layer structure or a frame structure for placing goods. When the shielding layer 14 is a layer structure or a frame structure on which goods can be placed, the pallet 11 can also be installed on the shielding layer 14, but since there is no shielding on the shielding layer 14, the pallet 11 can be fixedly installed on the shielding layer 14. The storage layer 15 can be a layer structure or a frame structure. The storage layer 15 is located directly below the shielding layer 14. The storage layer 15 can be provided with one or more layers, which is not specifically limited here. The layer height of the storage layer 15 is the spacing between adjacent storage layers 15 or the spacing between the storage layer 15 and the adjacent shielding layer 14.
[0029] In some embodiments, a plurality of cargo pallets 11 are arranged on the storage layer 15 at intervals along a second direction, the second direction is perpendicular to the first direction, and the second direction is the length direction of the storage layer 15. The number of cargo pallets 11 can be adaptively set according to the specific length of the storage layer 15 to ensure that the cargo pallets 11 can stably move relative to the storage layer 15.
[0030] The driving mechanism 12 and the cargo tray 11 are arranged in a one-to-one correspondence, and the driving mechanism 12 can be a cylinder.
[0031] The number of slide rails 13 corresponding to each pallet 11 can be adaptively set according to the length of the pallet 11 to ensure that the pallet 11 moves smoothly.
[0032] In some embodiments, at least one storage space bottom plate 16 is installed on the cargo pallet 11 , and a storage space is arranged on the storage space bottom plate 16 .
[0033] Specifically, each cargo pallet 11 may be provided with three storage spaces on the bottom plate 16 , so that each cargo pallet 11 has three storage spaces. The driving mechanism 12 may drive the corresponding cargo pallet 11 to synchronously move the three storage spaces on the cargo pallet 11 out of the storage layer 15 .
[0034] See also Figure 3 As shown, in order to improve the adaptability of each bin, each bin can be used to place goods of different sizes. Specifically, each bin includes a first bin for placing a wafer box and a second bin for placing a wafer tray carrier, and the first bin is located inside the second bin. The first bin is formed by a plurality of first blocks 17 mounted on the bin bottom plate 16, and the second bin is formed by a plurality of second blocks 18 mounted on the bin bottom plate 16, and the plurality of second blocks 18 are surrounded by the periphery of the plurality of first blocks 17, and the second blocks 18 at least partially extend above the first blocks 17 to prevent the first blocks 17 from affecting the enclosure of the second blocks 18.
[0035] When the storage space bottom plate 16 is used to place a wafer box, the wafer box can be placed in a first storage space formed by a first baffle. Multiple first baffles are arranged around the wafer box to limit the wafer box and prevent the wafer box from shaking relative to the retractable shelf during the movement of the retractable shelf.
[0036] When the storage space bottom plate 16 is used to place a wafer tray carrier, the wafer tray carrier can be placed in a second storage space formed by a second baffle. At this time, the wafer tray carrier is located above the first baffle 17 and is supported by multiple first baffles 17 or multiple second baffles, and the wafer tray carrier is stopped by multiple second baffles on all sides to prevent the wafer tray carrier from shaking relative to the retractable shelf during the movement of the retractable shelf.
[0037] In some embodiments, four first stoppers 17 are provided, respectively disposed near the four corners of the bin bottom plate 16. Each first stopper 17 includes a first support portion 171 and a first side stopper 172 disposed at the top edge of the first support portion 171. The first support portion 171 and the first side stopper 172 are both generally L-shaped, and one side of the first support portion 171 extends toward the inside of the first side stopper 172, so that the first in-position sensor 19 can be subsequently installed in the first support portion 171. The first side stopper 172 is disposed inside the first support portion 171 to form a first bin.
[0038] When the wafer box is placed on the first position, the first support portion 171 supports the wafer box, and the first side stop portion 172 stops the wafer box from all sides, so that the wafer box can be stably limited on the corresponding position bottom plate 16.
[0039] There are also four second stoppers 18, which are respectively arranged near the four corners of the bin bottom plate 16 and are located at the relatively outer sides of the four first stoppers 17. The second stopper 18 includes a second support portion 181 and a second side stop portion 182. The second support portion 181 is generally rectangular, and the second side stop portion 182 is generally L-shaped. The second side stop portion 182 is arranged at the top edge of the second support portion 181, so that a second in-position sensor 20 for detecting whether the wafer tray carrier is correctly placed in the second bin is subsequently installed inside the second support portion 181 and inside the second side stop portion 182. The height of the second support portion 181 on the bin bottom plate 16 is not lower than the height of the first side stop portion 172 on the bin bottom plate 16.
[0040] When the wafer tray carrier is placed on the second position, the second supporting portion 181 supports the wafer tray carrier, and the second side stop portion 182 stops the wafer tray carrier from all sides, so that the wafer tray carrier can be stably limited on the corresponding position bottom plate 16.
[0041] In some embodiments, a first guide portion 173 is disposed on the first side stop 172 , and the first guide portion 173 is inclined downward from the top of the first side stop 172 so as to guide the wafer box to fall into the first bin.
[0042] A second guide portion 183 is disposed on the second side stop 182 . The second guide portion 183 is inclined downward from the top of the second side stop 182 so as to guide the wafer tray carrier to fall into the second bin.
[0043] In some embodiments, a limit rod 21 is fixedly installed at both ends of each storage space bottom plate 16, which is used to stop the goods after the goods are separated from the stop of the first stop block 17 or the second stop block 18 to prevent the goods from falling out of the storage space bottom plate 16.
[0044] Furthermore, a third guide portion 22 is provided at the top of each limiting rod 21 , and the third guide portion 22 is inclined downward from the top of the limiting rod 21 to guide the goods to fall onto the corresponding storage space bottom plate 16 .
[0045] The retractable shelf further includes two first in-position sensors 19 and two second in-position sensors 20. The two first in-position sensors 19 are respectively arranged in the first supporting parts 171 of the two first stoppers 17 along the diagonal lines of the first bin, and the two second in-position sensors 20 are respectively arranged in the second supporting parts 181 of the two second stoppers 18 along the diagonal lines of the second bin. The first avoiding holes corresponding to the first in-position sensors 19 and the second in-position sensors 20 are respectively provided on the top surfaces of the first supporting parts 171 and the second supporting parts 181, so that the detection signals of the first in-position sensors 19 and the second in-position sensors 20 can pass through.
[0046] When the first bin on the bin floor 16 is used to place the goods, the two first in-position sensors 19 can simultaneously detect the goods to determine whether the goods are accurately placed in the first bin. When the second bin on the bin floor 16 is used to place the goods, the two second in-position sensors 20 can simultaneously detect the goods to determine whether the goods are accurately placed in the second bin, so as to ensure that the goods are stably placed on the bin floor 16.
[0047] A occupancy sensor (not shown) is provided under each storage space bottom plate 16, and the occupancy sensor can detect whether goods are placed on the corresponding storage space bottom plate 16. The occupancy sensor can be fixedly mounted on the bottom of the cargo pallet 11 and be hidden. A second avoidance hole 23 corresponding to the occupancy sensor is provided on the cargo pallet 11 and the storage space bottom plate 16 to avoid the detection signal sent by the occupancy sensor.
[0048] See also Figure 1 and Figure 2As shown, the retractable shelf further includes a display screen 24 for displaying cargo information on the retractable shelf. The display screen 24 is mounted on the shelf body 10 with an adjustable tilt angle.
[0049] Specifically, a bracket 25 is fixedly installed on the top of the frame 10, and a connecting member 26 assembled with the bracket 25 is fixedly installed on the back of the display screen 24. Among them, the connecting member 26 is provided with mounting circular holes 27 and arc-shaped adjustment waist holes 28 spaced apart in the horizontal direction, and the mounting circular holes 27 are relatively close to the display screen 24, and the arc of the arc-shaped adjustment waist hole 28 is set along the adjustment track of the display screen 24. The connecting member 26 and the bracket 25 are respectively connected in an adjustable fixed manner by a first bolt passing through the mounting circular hole 27 and a second bolt passing through the arc-shaped adjustment waist hole 28. The present application can make the display screen 24 rotate relative to the bracket 25 around the first bolt through the arc-shaped adjustment waist hole 28 to adjust the inclination between the display screen 24 and the horizontal plane, so as to adjust the display screen 24 to a suitable angle for the staff to watch the content on the display screen 24.
[0050] The retractable shelf also includes a barcode reader 29 corresponding to each bin. Each barcode reader 29 is located above the corresponding bin and is used to read the barcode information on the goods after the goods are placed on the bin, and transmit the barcode information to the display screen 24 for summary and display. The staff can intuitively know the goods information on the retractable shelf by checking the display screen 24, without having to check one by one, which is convenient and quick.
[0051] A plurality of universal wheels 30 are installed at the bottom of the frame 10 so that the frame 10 can move smoothly. The specific number of the universal wheels 30 can be determined according to actual conditions and is not limited here.
[0052] A plurality of feet 31 are installed at the bottom of the frame 10, and the levelness of the frame 10 can be adjusted and the frame 10 can be stably placed on the ground by adjusting the feet 31. The specific number of the feet 31 can be determined according to actual conditions and is not limited here.
[0053] A grounding wire 32 in contact with the ground is also installed at the bottom of the rack 10 to conduct static electricity on the rack 10 to the ground to prevent static electricity from damaging goods placed on the rack 10.
