[0016] When the lifting cylinder lifts the target material box and disengages it from the first transmission belt, the piston rods of the first clamping cylinder and the second clamping cylinder move toward each other to clamp the target material box.

[0017] Furthermore, there are multiple first clamping cylinders, and the multiple first clamping cylinders are spaced apart along the first direction X on the first side plate;

[0018] The number of the second clamping cylinders is multiple, and the multiple second clamping cylinders are arranged at intervals along the first direction X on the second side plate.

[0028] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0029] The storage and retrieval device provided in this embodiment includes a translation mechanism and a gripping mechanism. The translation mechanism includes a base and a first driving member, a first transmission wheel, and a first transmission belt disposed on the base. The first transmission belt is wound around the first transmission wheel. During operation, the first driving member drives the first transmission wheel to convey a material box along a first direction X via the first transmission belt. The first transmission belt has a first mounting portion, and the gripping mechanism is mounted on the first mounting portion so that during operation, the first driving member drives the first transmission wheel to move the gripping mechanism via the first transmission belt, thereby delivering the gripping mechanism to a designated position in the first direction X. When retrieving material, when the drive motor drives the drive screw to move towards the target material box, the gripping mechanism hook will eventually connect with the target material box. Thus, when the first transmission belt drives the gripping mechanism to move in the opposite direction, the gripping mechanism can move the target material box together, thereby moving the target material box above the first transmission belt. During unloading, the target bin is positioned on the first transmission belt. The first transmission belt and the gripping mechanism drive the target bin to move towards the shelf. Once the target bin reaches the shelf, the gripping mechanism unlocks from the target bin and moves away from the shelf to reset. The storage and retrieval device provided in this embodiment achieves bin storage and retrieval through a translation mechanism and a gripping mechanism, which can save space and improve space utilization.

[0045] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0046] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the storage cabinet provided in this embodiment includes a shelf 1 and a storage and retrieval device: the shelf 1 is provided with multiple layers of support members 11 at equal intervals, and the support members 11 form storage positions for placing one or more material boxes 6; optionally, the shelf 1 is provided with multiple layers and multiple rows of support members 11 at equal intervals, so that the storage positions are arranged in an array.

[0047] The storage and retrieval device provided in this embodiment includes a translation mechanism 3 and a gripping mechanism 2. The translation mechanism 3 includes a base 31 and a first driving member 32, a first transmission wheel 321, and a first transmission belt 33 disposed on the base 31. The first transmission belt 33 is wound around the first transmission wheel 321. During operation, the first driving member 32 drives the first transmission wheel 321 to convey the material box 6 along the first direction X via the first transmission belt 33. The first transmission belt 33 is provided with a first mounting part, and the gripping mechanism 2 is mounted on the first mounting part so that during operation, the first driving member 32 drives the first transmission wheel 321 to move via the first transmission belt 33, thereby delivering the gripping mechanism 2 to a designated position in the first direction X. When retrieving material, the drive motor 24 drives the drive screw 22 to move towards the target material box 6. The hook 25 of the gripping mechanism 2 then connects with the target material box 6. Thus, when the first transmission belt 33 drives the gripping mechanism 2 to move in the opposite direction, the gripping mechanism 2 can move the target material box 6 together, thereby moving the target material box 6 above the first transmission belt 33. When unloading, the target material box 6 is positioned on the first transmission belt 33. The first transmission belt 33 and the gripping mechanism 2 drive the target material box 6 to move towards the shelf 1. After the target material box 6 reaches the shelf 1, the gripping mechanism 2 unlocks from the target material box 6 and moves away from the shelf 1 to reset. The storage and retrieval device provided in this embodiment achieves storage and retrieval of the material box 6 through the translation mechanism 3 and the gripping mechanism 2, which can save space and improve space utilization.

[0048] In some specific embodiments, the gripping mechanism 2 includes a first connecting block 21, a drive screw 22, a screw nut 23, and a drive motor 24. The first connecting block 21 is connected to the first mounting part, the screw nut 23 is connected to the first connecting block 21, and the drive screw 22 is threadedly engaged with the screw nut 23. The drive motor is located on the first connecting block 21 and is used to drive the drive screw 22. Hooks 25 are provided at both ends of the drive screw 22, and the hooks 25 are used to lock with the target material box 6. When the drive motor 24 drives the drive screw 22 to move towards the target material box 6, the hooks 25 will eventually connect with the target material box 6, i.e., the hooks 25 lock with the target material box 6. Thus, when the first transmission belt 33 drives the gripping mechanism 2 to move in the opposite direction, the gripping mechanism 2 can move the target material box 6 together, thereby moving the target material box 6 above the first transmission belt 33. In some specific embodiments, with the cooperation of the lifting mechanism 4 and the conveying mechanism 5, the target material box 6 can be moved to a set position.

[0049] Optionally, the target material box 6 is provided with a slot 63, and the hook 25 is inserted into the slot 63, so that the gripping mechanism 2 can be connected to the target material box 6.

[0050] The drive screw 22 has hooks 25 at both ends. Specifically, shelves 1 can be set on both sides of the storage and retrieval device, with each hook 25 corresponding to one shelf 1, enabling retrieval from both sides and further reducing the size of the storage and retrieval device in the first direction X. In addition, the two shelves 1 share one storage and retrieval device, which can increase material storage space and reduce the overall system cost.

[0051] In some specific embodiments, the base 31 includes a first side plate 311 and a second side plate 312. The first side plate 311 and the second side plate 312 are respectively disposed on both sides of the conveying direction of the first transmission belt 33. The first side plate 311 is provided with a first slide rail 311a, and the second side plate 312 is provided with a second slide rail 312a. Both the first slide rail 311a and the second slide rail 312a extend along the first direction X. The first connecting block 21 is connected to a first slider 34 and a second slider 35. The first slider 34 is slidably engaged with the first slide rail 311a, and the second slider 35 is slidably engaged with the second slide rail 312a, so that the gripping mechanism 2 runs more smoothly and the stability of the gripping mechanism 2 is improved.

[0052] In some specific embodiments, the translation mechanism 3 includes a lifting cylinder 36, a first clamping cylinder 37, and a second clamping cylinder 38. The cylinder body of the lifting cylinder 36 is mounted on the bottom of the base 31, and the piston rod of the lifting cylinder 36 faces the bottom of the target material box 6 to move the target material box 6 up and down. The cylinder body of the first clamping cylinder 37 is disposed on the first side plate 311, and the piston rod of the first clamping cylinder 37 faces the first side plate 311 of the target material box 6. The cylinder body of the second clamping cylinder 38 is disposed on the second side plate 312, and the piston rod of the second clamping cylinder 38 faces the second side plate 312 of the target material box 6. When the lifting cylinder 36 lifts the target material box 6 and disengages it from the first transmission belt 33, the piston rods of the first clamping cylinder 37 and the second clamping cylinder 38 move toward each other to clamp the target material box 6. When the drive motor 24 drives the drive screw 22 to move toward the target material box 6, the hook 25 of the gripping mechanism 2 will eventually connect with the target material box 6. Thus, when the first transmission belt 33 drives the gripping mechanism 2 to move in the opposite direction, the gripping mechanism 2 can move the target material box 6 together, thereby moving the target material box 6 above the first transmission belt 33. In some specific embodiments, the hook 25 of the gripping mechanism 2 is unlocked from the target material box 6. Under the action of the lifting cylinder 36, the target material box 6 can be lifted up to a height greater than the height of the target material box 6. Under the combined action of the first clamping cylinder 37 and the second clamping cylinder 38, the lifted target material box 6 can be clamped to prevent it from falling. Afterwards, the lifting cylinder 36 is reset, and the drive motor 24 drives the drive screw 22 to move towards the direction closer to the second target material box 6. The hook 25 of the gripping mechanism 2 is connected to the second target material box 6. Thus, when the first transmission belt 33 drives the gripping mechanism 2 to move in the opposite direction, the gripping mechanism 2 can move the second target material box 6 together, thereby moving the second target material box 6 above the first transmission belt 33.

[0053] In some specific embodiments, there are multiple first clamping cylinders 37, which are spaced apart along the first direction X on the first side plate 311; there are multiple second clamping cylinders 38, which are spaced apart along the first direction X on the second side plate 312, which can improve the stability of the clamping box 6.

[0054] In some specific embodiments, the hook 25 includes a bent portion that bends downwards or upwards. The target material box 6 is provided with a slot 63, and the bent portion engages with the slot 63. Specifically, when the bent portion bends downwards, the initial position of the hook 25 can be higher than the slot 63. The hook 25 can move downwards under the action of the lifting mechanism 4 to engage with the slot 63, and then move out of or into the shelf 1 under the action of the translation mechanism 3. When the bent portion bends upwards, the initial position of the hook 25 can be lower than the slot 63. The hook 25 can move upwards under the action of the lifting mechanism 4 to engage with the slot 63, and then move out of or into the shelf 1 under the action of the translation mechanism 3.

[0055] In some specific embodiments, the material bin 6 includes a third side plate and a fourth side plate arranged opposite to each other. The third side plate is provided with a hook 61, and the fourth side plate is provided with a plug-in part 62. Adjacent material bins 6 include a first material bin 6 and a second material bin 6. The hook 61 of the first material bin 6 is engaged with the plug-in part 62 of the second material bin 6. When one of the two adjacent material bins 6 is located in the translation mechanism 3, it can be moved up and down by the lifting mechanism 4, so that the hook 61 of the first material bin 6 can be engaged or disengaged from the plug-in part 62 of the second material bin 6. By connecting with hooks, multiple material bins 6 can be pulled out.

[0056] The insertion part 62 can be a slot 63, or a groove-shaped structure or a hole-shaped structure in a different position from the slot 63.

[0057] In some specific embodiments, a clearance portion 39 is formed between the first connecting block 21 and the bottom of the base 31 to avoid the piston rod of the lifting cylinder 36, so as to facilitate the movement of the gripping mechanism in the first direction X.

[0058] In some specific embodiments, the first connecting block 21 is provided with a guide sleeve 28, and a guide post 26 is inserted into the guide sleeve 28. The two ends of the guide post 26 are respectively connected to a hook 25, which can improve the stability of the material box 6 movement.

[0059] In some specific embodiments, the storage and retrieval device includes a frame 50 and a gripping mechanism 2, a translation mechanism 3, a lifting mechanism 4 and a conveying mechanism 5 installed on the frame 50. The gripping mechanism 2, the translation mechanism 3, the lifting mechanism 4 and the conveying mechanism 5 facilitate the storage and retrieval of the material bins 6, optimize the layout of the storage cabinet, improve the utilization rate of the storage cabinet, and at the same time make the material bins 6 stacked neatly and orderly.

[0060] The gripping mechanism 2 is set on the translation mechanism 3. The translation mechanism 3 is used to place the target material box 6. The translation mechanism 3 is used to drive the gripping mechanism 2 to reciprocate along the first direction X. The translation mechanism 3 is installed on the lifting mechanism 4. The lifting mechanism 4 is used to drive the translation mechanism 3 to move up and down along the height direction Z. The lifting mechanism 4 is installed on the conveying mechanism 5. The conveying mechanism 5 is used to drive the lifting mechanism 4 to move along the second direction Y. During loading, the material box 6 is placed above the translation mechanism 3. The horizontal position of the translation mechanism 3 is adjusted by the conveying mechanism 5, and the height position of the translation mechanism 3 is adjusted by the lifting mechanism 4. The translation mechanism 3 is aligned with the corresponding support member 11 by the conveying mechanism 5 and the lifting mechanism 4. The material box 6 is pushed to the support member 11 by the translation mechanism 3 and the gripping mechanism 2. During unloading, the translation mechanism 3 is aligned with the support member 11 of the unloading box 6 by the conveying mechanism 5 and the lifting mechanism 4. The gripping mechanism 2 is connected to the unloading box 6. The unloading box 6 is pulled to the gripping mechanism 2 by the translation mechanism 3. Then the unloading box 6 is lowered by the lifting mechanism 4. The unloading box 6 is moved to the set position by the conveying mechanism 5.

[0061] The gripping mechanism 2 is used to lock with the target bin 6. During loading, the target bin 6 is positioned on the lifting mechanism 4, and the gripping mechanism 2 locks with the target bin 6. When the translation mechanism 3, lifting mechanism 4, and conveying mechanism 5 drive the target bin 6 to be positioned at the target storage location, the gripping mechanism 2 unlocks from the target bin 6. During unloading, the translation mechanism 3, lifting mechanism 4, and conveying mechanism 5 drive the gripping mechanism 2 to lock with the target bin 6 at the target storage location. The translation mechanism 3 drives the target bin 6 to move to the lifting mechanism 4, facilitating the storage and retrieval of the bin 6, optimizing the layout of the storage cabinet, improving the utilization rate of the storage cabinet, and ensuring that the bins 6 are stacked neatly and orderly. This embodiment of the present disclosure utilizes the method of extracting the bin 6 to store and retrieve the bin 6, enabling front-to-back and top-to-bottom retrieval of goods, achieving high-density space utilization.

[0062] In some specific embodiments, the translation mechanism 3 includes a lifting cylinder 36, a first clamping cylinder 37, and a second clamping cylinder 38. The cylinder body of the lifting cylinder 36 is mounted on the bottom of the base 31, and the piston rod of the lifting cylinder 36 faces the bottom of the target material box 6 to move the target material box 6 up and down. The cylinder body of the first clamping cylinder 37 is disposed on the first side plate 311, and the piston rod of the first clamping cylinder 37 faces the first side plate 311 of the target material box 6. The cylinder body of the second clamping cylinder 38 is disposed on the second side plate 312, and the piston rod of the second clamping cylinder 38 faces the second side plate 312 of the target material box 6. When the lifting cylinder 36 lifts the target material box 6 and disengages it from the first transmission belt 33, the piston rods of the first clamping cylinder 37 and the second clamping cylinder 38 move toward each other to clamp the target material box 6.

[0063] When the drive motor 24 drives the drive screw 22 to move toward the target material box 6, the hook 25 of the gripping mechanism 2 will eventually connect with the target material box 6. Thus, when the first transmission belt 33 drives the gripping mechanism 2 to move in the opposite direction, the gripping mechanism 2 can move the target material box 6 together, thereby moving the target material box 6 above the first transmission belt 33. In some specific embodiments, the hook 25 of the gripping mechanism 2 is unlocked from the target material box 6. Under the action of the lifting cylinder 36, the target material box 6 can be lifted up to a height greater than the height of the target material box 6. Under the combined action of the first clamping cylinder 37 and the second clamping cylinder 38, the lifted target material box 6 can be clamped to prevent it from falling. Afterwards, the lifting cylinder 36 is reset, and the drive motor 24 drives the drive screw 22 to move towards the direction closer to the second target material box 6. The hook 25 of the gripping mechanism 2 is connected to the second target material box 6. Thus, when the first transmission belt 33 drives the gripping mechanism 2 to move in the opposite direction, the gripping mechanism 2 can move the second target material box 6 together, thereby moving the second target material box 6 above the first transmission belt 33. In some specific embodiments, the gripping mechanism 2 unlocks the hook 25 from the second target material box 6. Under the action of the lifting cylinder 36, the second target material box 6 can be lifted up to a height greater than the target material box 6. Under the combined action of the first clamping cylinder 37 and the second clamping cylinder 38, the lifted second target material box 6 can be clamped to prevent it from falling. Afterwards, the lifting cylinder 36 resets. Repeating the above actions allows multiple material boxes 6 to be picked up, and these material boxes 6 can be transported to the discharge port at one time through the cooperation of the lifting mechanism 4 and the conveying mechanism 5. Repeating the above actions allows multiple material boxes 6 to be picked up, enabling small-batch buffered outbound processing, saving outbound time, and these material boxes 6 can be transported to the discharge port at one time through the cooperation of the lifting mechanism 4 and the conveying mechanism 5.

[0064] The storage process is the reverse of the retrieval process. Initially, multiple boxes 6 can be stacked on the translation mechanism 3. The lifting cylinder 36 lifts the boxes 6 to a height greater than the target box 6. Under the combined action of the first clamping cylinder 37 and the second clamping cylinder 38, the second-to-last box 6 (the second box 6 from the bottom) is clamped. The lifting cylinder 36 then resets, and the bottom target box 6 is positioned on the translation mechanism 3. The drive motor 24 drives the drive screw 22 to move towards the support member 11. Driven by the gripping mechanism 2 and the translation mechanism 3, the target box 6 moves to the support frame. Afterward, the gripping mechanism 2 unlocks from the target box 6 and resets. Repeating this process allows the stacked boxes 6 to be placed into the shelf 1 sequentially.

[0065] In this embodiment, the material box 6 is accessed by pulling it out, which avoids using a method that is too tall and saves space.

[0066] In some specific embodiments, the lifting mechanism 4 includes a support base 41 and a column 42. The bottom of the column 42 is disposed on the support base 41, and the column 42 is fixedly connected to the support base 41. The column 42 extends along the height direction Z. The column 42 is provided with a second driving member 43, a second transmission wheel, and a second transmission belt. The second transmission belt is wound around the second transmission wheel and is provided with a second mounting part. The translation mechanism 3 is mounted on the second mounting part. During the operation of the second transmission wheel driven by the second driving member 43, the translation mechanism 3 can be transmitted along the height direction Z through the second transmission belt, thereby delivering the translation mechanism 3 to a designated position in the height direction Z.

[0067] In some specific embodiments, the conveying mechanism 5 includes a rack 51 disposed on the frame 50, the rack 51 extending along the second direction Y, and a support base 41 provided with a third driving member 52. The output end of the third driving member 52 is connected to a gear, which meshes with the rack 51. The support base 41 is moved via gear and rack transmission without manual operation, reducing costs. Furthermore, the gear and rack transmission provides stability and accuracy, ensuring product quality and precision, and improving work efficiency.

[0068] The first driving component 32, the second driving component 43, and the third driving component 52 can all be motors.

[0069] In some specific embodiments, the frame 50 is provided with a first guide rail 53 and a second guide rail 54, both of which are connected to the frame 50. Both the first guide rail 53 and the second guide rail 54 extend along the second direction Y. The first guide rail 53 and the second guide rail 54 are respectively disposed on both sides of the rack 51. The support base 41 is provided with a third slider 55 and a fourth slider 56. The third slider 55 is slidably engaged with the first guide rail 53, and the fourth slider 56 is slidably engaged with the second guide rail 54, thereby improving the stability of the lifting mechanism 4 moving in the second direction Y.

[0070] In some specific embodiments, the frame 50 is provided with a crossbeam 57, which is connected to the frame 50. The crossbeam 57 is provided with a guide post 58, which is connected to the crossbeam 57. The guide post 58 extends along the second direction Y. The top of the column 42 is provided with a guide sleeve 59. The guide post 58 and the guide sleeve 59 slide together, which improves the stability of the lifting mechanism 4 moving in the second direction Y.

[0071] In some specific embodiments, the support member 11 includes a side baffle 111 extending along the first direction X and a bottom support plate 112. The target material box 6 is inserted into the support member 11 along the first direction X and supported on the bottom support plate 112, which facilitates the storage and retrieval of materials, optimizes the layout of the storage cabinet, improves the utilization rate of the storage cabinet, and makes the material boxes stacked neatly and orderly.
