[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the fixed scope of the present utility model.

[0034] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0035] Before explaining the electrode roll transportation and storage device provided in the embodiments of this application, the application scenarios of the electrode roll transportation and storage device provided in the embodiments of this application will be specifically described:

[0036] A battery pack consists of battery cells and electrodes connected to the cells. As the core component of the battery pack, the electrodes are typically formed by uniformly coating active material onto the surface of metal foil using a continuous coating process. These electrodes are then processed into rolls using a winding machine; these rolled products are called electrode rolls. Furthermore, the electrode rolls have an internal hole running through their center along the axial direction. During the production process, electrode rolls undergo multiple transfers, temporary storage, and distribution to meet the material flow requirements between different processes.

[0037] Currently, in the processing of power batteries, the transfer and storage of electrode rolls mainly rely on a combination of manual labor and handling equipment. Specifically, operators first transport the electrode rolls to designated temporary storage areas or warehouses using specialized handling vehicles. Once the handling vehicles are in place, operators must manually unload the electrode rolls from the vehicles and move them by hand or with simple tools to fixed storage racks, pallets, or automated storage units for storage. Correspondingly, when subsequent processes require the use of electrode rolls, operators must manually remove them from the storage devices, return them to the handling vehicles, and then the vehicles transport them to the next processing point.

[0038] However, due to the weight and volume of the electrode rolls, manual handling is inefficient and cannot meet the needs of large-scale, fast-paced production of power batteries. At the same time, the electrode rolls are prone to bumps, scratches or drops during manual handling, which may cause damage or deformation to the electrode surface, thereby affecting the performance consistency and yield of the final battery products.

[0039] To solve the above problems, such as Figure 1 As shown, this application provides an electrode roll transport and storage device, including: a storage device 1, the storage device 1 having intersecting first direction X and second direction Y, the first direction X being the height direction of the storage device 1, the storage device 1 including a first frame 11 and a first shaft 12, the first shaft 12 being fixedly connected to the first frame 11, the first shaft 12 extending along the second direction Y; and a transport device 2, including a second frame 21, a second shaft 22 and a pushing mechanism 23, the second frame 21 being movable relative to the first frame 11, the second shaft 22 being vertically and vertically connected to the second frame 21 along the first direction X, and the pushing mechanism 23 being movably connected to the second shaft 22 along the second direction Y to push the electrode roll from the second shaft 22 to the first shaft 12.

[0040] In this embodiment, the electrode roll transport and storage equipment includes a storage device 1 and a handling device 2, which realize the storage and transfer of electrode rolls. The storage device 1 has a first direction X and a second direction Y in space, wherein the first direction X is defined as the height direction of the electrode roll transport and storage equipment, and the second direction Y intersects the first direction X. Exemplarily, the second direction Y is perpendicular to the first direction X.

[0041] The following description will use the example of the second direction Y being perpendicular to the first direction X to illustrate the embodiments of this application. It can be understood that the first direction X is the height direction of the electrode roll transport and storage device, and the second direction Y is the width direction of the electrode roll transport and storage device.

[0042] The storage device 1 includes a first frame 11 and a first shaft 12. The first frame 11 includes components such as uprights, diagonal braces, crossbars, and platforms, which are assembled to form a frame structure. The first shaft 12 is connected to the first frame 11 and is supported by the first frame 11. The first shaft 12 extends along a second direction Y and is fixedly installed on the first frame 11. The first shaft 12 can carry and store electrode rolls.

[0043] It should be noted that the first frame 11 may also be equipped with a linear push module such as a cylinder or hydraulic cylinder, so as to push the pole roll on the first shaft 12 along the second direction Y through the linear push module, thereby facilitating the movement of the pole roll on the first shaft 12.

[0044] The conveying device 2 in this embodiment includes a second frame 21, a second shaft 22, and a pushing mechanism 23. The second frame 21 includes components such as uprights, diagonal braces, crossbars, and platforms, which are assembled to form a frame structure. The second shaft 22 is connected to the second frame 21 to support the second shaft 12. The second frame 21 is movable relative to the first frame 11, allowing it to move closer to or further away from the storage device 1.

[0045] The second frame 21 is also equipped with a lifting mechanism. The fixed end of the lifting mechanism is connected to the second frame 21, and the driving end of the lifting mechanism is connected to the second shaft 22. The lifting mechanism can drive the second shaft 22 to move relative to the second frame 21 along the first direction X, so as to adjust the second shaft 22 to align with the first shaft 12 of the storage device 1 along the second direction Y. For example, the lifting mechanism can be a servo electric cylinder or a chain lifting mechanism.

[0046] The pushing mechanism 23 is movably connected to the second shaft 22 along the second direction Y. When the second shaft 22 is connected to the first shaft 12, the pushing mechanism 23 can push the pole roll to transfer the pole roll from the second shaft 22 to the first shaft 12.

[0047] It should be noted that the docking of the first shaft 12 and the second shaft 22 means that the axial direction of the first shaft 12 and the axial direction of the second shaft 22 are at the same height along the first direction X, and the end of the first shaft 12 away from the first frame 11 docks with the end of the second shaft 22 away from the second frame 21.

[0048] For example, the first frame 11 and the second frame 21 may be welded from high-strength steel to ensure the overall rigidity and stability of the first frame 11 and the second frame 21.

[0049] like Figure 3 As shown, the storage device 1 includes multiple first shafts 12. The multiple first shafts 12 are fixedly installed on the first frame 11 at a preset interval, and the distance between two adjacent first shafts 12 should be at least greater than the maximum outer diameter of two adjacent pole rolls, so that each pole roll will not interfere with each other after being stored in the corresponding first shaft 12, so that multiple pole rolls can be stored on the storage device 1, thereby improving the space utilization of the storage device 1.

[0050] Furthermore, by providing multiple first shafts 12 on the first frame 11, it can be ensured that the handling device 2 can simultaneously transport multiple electrode rolls during one operation and store the transported electrode rolls on the storage device 1, thereby improving the efficiency of a single operation and enabling the device to adapt to the needs of batch electrode roll transportation and storage operations.

[0051] For example, along the second direction Y, two, three, four, five, or six first axes 12 can be spaced apart on the first frame 11. In this embodiment, the specific number of first axes 12 is not limited. In practical applications, technicians can set the specific number of first axes 12 as needed.

[0052] In addition, the surfaces of the first shaft 12 and the second shaft 22 can be hardened alloy steel, with an outer diameter slightly smaller than the diameter of the inner hole of the pole roll, so that the pole roll can be inserted into the first shaft 12 or the second shaft 22.

[0053] Furthermore, rolling elements can be added to the surfaces of the first shaft 12 and the second shaft 22 to reduce frictional loss on the surfaces of the first shaft 12 and the second shaft 22 during the pole roll pushing process.

[0054] The pushing mechanism 23 can be a linear module driven by a servo motor or a push plate mechanism controlled by a cylinder to ensure the smoothness of pushing the pole roll along the second axis 22.

[0055] In practical applications, when storing electrode rolls, the transport device 2 carrying the electrode rolls moves to one side of the storage device 1. The height of the second shaft 22 is adjusted to be at the same level as the first shaft 12. Then, the second frame 21 continues to move along the second direction Y until the second shaft 22 aligns with the first shaft 12. Subsequently, the second pushing mechanism 23 actuates, smoothly pushing the electrode rolls on the second shaft 22 onto the first shaft 12, completing the storage of the electrode rolls. This entire process reduces the degree of manual intervention, improves the efficiency and safety of electrode roll transportation and storage, reduces the labor intensity of operators, and minimizes electrode roll collisions and quality damage caused by improper manual operation. It is suitable for large-scale, high-frequency electrode roll transportation and storage scenarios.

[0056] In some embodiments, the pushing mechanism 23 includes a first driving member 231 and a pushing part 232. The pushing part 232 is slidably connected to the second shaft 22 along the second direction Y, and the first driving member 231 is drively connected to the pushing part 232 to push the pushing part 232 to slide along the second direction Y.

[0057] In this embodiment, the pushing mechanism 23 includes a first driving member 231 and a pushing part 232. The pushing part 232 is slidably connected to the surface of the second shaft 22 along the second direction Y. The driving end of the first driving member 231 is connected to the pushing part 232 and is used to drive the pushing part 232 to slide axially along the second shaft 22. The first driving member 231 can be a linear driving device such as a hydraulic cylinder or a pneumatic cylinder, and the pushing part 232 can be an alloy push plate or a push block.

[0058] When it is necessary to store the electrode roll, the first drive unit 231 is activated, driving the pusher 232 to slide smoothly along the second axis 22 until the pusher 232 is in contact with the end face of the electrode roll and continuously applies a uniform axial thrust, pushing the electrode roll to move along the second axis 22 until it is completely transferred to the first axis 12, realizing the automated storage of the electrode roll and improving the transportation and storage efficiency.

[0059] In some embodiments, the polar roll transport and storage device further includes a first positioning member 13 and a second positioning member 24. The first positioning member 13 is disposed at the end of the first shaft 12 away from the first frame 11, and the second positioning member 24 is disposed at the end of the second shaft 22 away from the second frame 21. The first positioning member 13 and the second positioning member 24 can be plugged into each other.

[0060] In this embodiment, the polar roll transport and storage equipment also includes a first positioning member 13 and a second positioning member 24. The first positioning member 13 is disposed at the end of the first shaft 12 away from the first frame 11, and the second positioning member 24 is disposed at the end of the second shaft 22 away from the second frame 21. The first positioning member 13 and the second positioning member 24 can be plugged into each other.

[0061] In other embodiments, the first positioning member 13 and the second positioning member 24 may adopt a complementary pluggable structure, specifically: the first positioning member 13 includes one of a protrusion or a groove, while the second positioning member 24 correspondingly includes the other of a protrusion or a groove. For example, the first positioning member 13 is a protrusion and the second positioning member 24 is a groove, or the first positioning member 13 is a groove and the second positioning member 24 is a protrusion.

[0062] In addition, the first positioning element 13 and the second positioning element 24 can also adopt other pluggable mating structures. For example, the first positioning element 13 can be a tapered guide pin, and the second positioning element 24 can be a tapered guide sleeve; or the first positioning element 13 can be a cross-shaped guide block, and the second positioning element 24 can be a cross-shaped guide groove; or the first positioning element 13 can be a V-shaped positioning groove, and the second positioning element 24 can be a V-shaped positioning block. Of course, the above are only individual examples of the specific structures of the first positioning element 13 and the second positioning element 24, and are not intended to limit this application. In practical applications, those skilled in the art can also choose a suitable structure as needed.

[0063] In the actual operation, when electrode rolls need to be stored, the conveying device 2 moves closer to the storage device 1, and the second positioning member 24 at the end of the second shaft 22 gradually approaches the first positioning member 13 at the end of the first shaft 12 as the second frame 21 moves. When the first positioning member 13 and the second positioning member 24 are fully inserted, the first shaft 12 and the second shaft 22 are aligned and coaxial, avoiding jamming or wear caused by axial deviation between the first shaft 12 and the second shaft 22 during the pushing process, thus improving the safety and operating efficiency of the equipment.

[0064] In some embodiments, the polar roll transport and storage device further includes a limiting mechanism 3, which is telescopically connected to the end side wall of the first shaft 12 away from the first frame 11 along a first direction X.

[0065] In this embodiment, the electrode roll transport and storage equipment further includes a limiting mechanism 3, which is disposed on the end side wall of the first shaft 12 away from the first frame 11. The limiting mechanism 3 is telescopically connected to the first shaft 12 along the first direction X. The limiting mechanism 3 may be a cylinder-driven telescopic pin, a servo electric cylinder-controlled stop, or an electromagnetically driven stop, etc.

[0066] Specifically, in the storage device 1, the extended limiting mechanism 3 and the first frame 11 together form a limiting space for the electrode roll on the first shaft 12, ensuring the electrode roll remains stable on the first shaft 12 and preventing it from slipping off the free end of the first shaft 12 due to inertia or accidental collision during storage. When the electrode roll is stored, the limiting mechanism 3 retracts, making way for an unobstructed path for the electrode roll to be pushed onto the first shaft 12. After the electrode roll is stored on the first shaft 12, the limiting mechanism 3 extends again to prevent the electrode roll from slipping off the free end of the first shaft 12, thus improving the safety of the device.

[0067] In some embodiments, such as Figures 2-4As shown, the end of the first shaft 12 away from the first frame 11 is provided with a groove, and the end of the second shaft 22 away from the second frame 21 is provided with a protrusion; the groove has a first opening 15, which faces the end away from the first frame 11, and the side wall of the first shaft 12 has a second opening 16, which communicates with the first opening 15. The limiting mechanism 3 includes: a push rod 31, which is inserted into the first shaft 12 through the first opening 15, and at least part of the push rod 31 is exposed outside the first shaft 12, with the exposed end of the push rod 31 used to dock with the protrusion; a telescopic component 32, which is inserted into the first shaft 12 through the second opening 16, with the end of the telescopic component 32 inserted into the first shaft 12 hinged to the end of the push rod 31 that extends into the first shaft 12; and a wedge-shaped member 33, which is connected along the first direction X to the side wall of the telescopic component 32 away from the push rod 31.

[0068] In this embodiment, a groove is provided at the end of the first shaft 12 away from the first frame 11, and a corresponding protrusion is provided at the end of the second shaft 22 away from the second frame 21. The inner wall of the groove matches the side wall of the protrusion, and the protrusion can be inserted into the groove. Furthermore, a first opening 15 is provided at the bottom of the groove, and a second opening 16 is provided on the side wall of the first shaft 12. The first opening 15, the inner cavity of the first shaft 12, and the second opening 16 are connected to form an L-shaped channel.

[0069] Furthermore, the limiting mechanism 3 includes a push rod 31, a telescopic assembly 32, and a wedge 33. Specifically, the push rod 31 is movably inserted into the inner cavity of the first shaft 12 through the first opening 15 and partially exposed outside the first shaft 12. The end of the push rod 31 partially exposed outside the first shaft 12 is called the outer end of the push rod, and the end of the push rod 31 inserted inside the first shaft 12 is called the inner end of the push rod. The outer end of the push rod is used to mate with the protrusion of the second shaft 22 when the second shaft 22 mates with the first shaft 12. The telescopic assembly 32 is inserted into the inner cavity of the first shaft 12 through the second opening 16, and the end of the telescopic assembly 32 inserted into the inner cavity of the first shaft 12 is hinged to the inner end of the push rod. The wedge 33 is fixed along the first direction X to the side wall of the telescopic assembly 32 away from the push rod 31.

[0070] When electrode rolls need to be stored, the second shaft 22 gradually approaches the first shaft 12 along the second direction Y until the protrusion at the end of the second shaft 22 contacts and pushes the outer end of the push rod, causing the push rod 31 to move into the inner cavity of the first shaft 12. The push rod 31 drives the telescopic assembly 32 to retract, and at the same time, the wedge 33 moves synchronously with the telescopic assembly 32, so that the part of the wedge 33 protruding from the surface of the first shaft 12 gradually becomes smaller until it completely enters the inner cavity of the first shaft 12, making an unobstructed passage for the electrode rolls, so that the pushing mechanism 23 can push the electrode rolls from the second shaft 22 to the first shaft 12. When the second shaft 22 completes the electrode roll transfer and separates from the first shaft 12 along the second direction Y, the protrusion at the end of the second shaft 22 gradually disengages from the outer end of the push rod, and the axial thrust on the push rod 31 disappears. At this time, the telescopic component 32 extends, causing the wedge 33 to extend from the second opening 16 until it protrudes from the surface of the first shaft 12. At this time, the first frame 11 and the wedge 33 together form a limiting space for the pole roll on the first shaft 12, which effectively prevents the pole roll from falling off the free end of the first shaft 12 through mechanical constraints.

[0071] The limiting mechanism 3 in this embodiment is triggered by the mechanical force generated during the docking process of the first shaft 12 and the second shaft 22. It does not require an additional power source and is suitable for automation scenarios that require frequent docking and separation. It ensures connection reliability and simplifies the complexity of the control system.

[0072] In some embodiments, the telescopic assembly 32 includes: a connecting rod 321, one end of which is hinged to the end of the push rod 31 that extends into the first shaft 12; a transmission member 322, one end of which is hinged to the other end of the connecting rod 321, the other end of which is hinged to the inner wall of the first shaft 12; and a wedge-shaped member 33 connected along the first direction X to the side wall of the transmission member 322 away from the push rod 31.

[0073] In some embodiments, the telescopic assembly 32 includes a connecting rod 321 and a transmission member 322. One end of the connecting rod 321 forms a rotating pair with the inner end of the push rod 31 via a pin. One end of the transmission member 322 is hinged to the other end of the connecting rod 321, and the other end of the transmission member 322 is connected to a bearing seat pre-set on the inner wall of the first shaft 12 via a rotating shaft. The wedge-shaped member 33 is made of wear-resistant copper alloy or surface-hardened tool steel, and is vertically connected to the side of the transmission member 322 opposite to the push rod 31 by bolt fixing or integral forming.

[0074] When polar rolls need to be stored, the second shaft 22 gradually approaches the first shaft 12 along the second direction Y until the protrusion at the end of the second shaft 22 contacts and pushes the outer end of the push rod, causing the push rod 31 to move into the inner cavity of the first shaft 12. The linear motion of the push rod 31 is converted into the oscillating motion of the transmission member 322 through the connecting rod 321. When the transmission member 322 rotates around its fixed hinge point, it drives the wedge member 33 to move in an arc trajectory, causing the wedge member 33 to gradually enter the inner cavity of the first shaft 12, making way for the polar rolls and facilitating the pushing mechanism 23 to push the polar rolls from the second shaft 22 to the first shaft 12. When the second shaft 22 completes the polar roll transfer and separates from the first shaft 12 along the second direction Y, the protrusion at the end of the second shaft 22 gradually detaches from the outer end of the push rod, and the axial thrust on the push rod 31 disappears. At this time, the elastic potential energy stored in the telescopic member 3223 begins to be released, pushing the transmission member 322 to rotate in the opposite direction around the fixed hinge point. The swing motion of the transmission component 322 is converted into the resetting motion of the push rod 31 through the connecting rod 321, causing the outer end of the push rod to move outwards from the first shaft 12 and return to its initial position. At the same time, the reverse rotation of the transmission component 322 drives the wedge-shaped component 33 to move outwards from the first shaft 12 along an arc trajectory, causing the wedge-shaped component 33 to gradually extend from the second opening 16 and protrude from the surface of the first shaft 12. Together with the first frame 11, it forms a limiting space for the pole rolls on the first shaft 12, effectively preventing the pole rolls from falling off the free end of the first shaft 12 and providing safety assurance for subsequent storage operations.

[0075] In some embodiments, the transmission member 322 includes: a fixed seat 3221, which is connected to the first shaft 12 and is disposed around the first opening 15; a transmission rod 3222, one end of which is hinged to the end of the connecting rod 321 away from the push rod 31, and the other end of which is hinged to the fixed seat 3221; a wedge-shaped member 33 is connected along the first direction X to the side wall of the transmission rod 3222 away from the push rod 31; and a telescopic member 3223, which is disposed between the transmission rod 3222 and the fixed seat 3221, with one end of the telescopic member 3223 abutting against the transmission rod 3222 and the other end abutting against the fixed seat 3221.

[0076] In this embodiment, the transmission component 322 includes a fixed base 3221, a transmission rod 3222, and a telescopic component 3223. The fixed base 3221 is an annular base, mounted around the inner wall of the first shaft 12 via an interference fit or bolt fixing. One end of the transmission rod 3222 is hinged to the end of the connecting rod 321 away from the push rod, and the other end is hinged to the fixed base 3221 to form a rotating pair. The telescopic component 3223 can be an elastic element such as a compression spring or a disc spring assembly, and its two ends can be connected to the transmission rod 3222 and the fixed base 3221 respectively via ball joints to ensure the stability of torque transmission.

[0077] When polar rolls need to be stored, the second shaft 22 gradually approaches the first shaft 12 along the second direction Y until the protrusion at the end of the second shaft 22 contacts and pushes the outer end of the push rod 31, causing the push rod 31 to move into the first shaft 12. The push rod 31 drives the transmission rod 3222 to rotate around the hinge point of the fixed seat 3221 through the connecting rod 321. The rotation of the transmission rod 3222 compresses the telescopic member 3223, causing the telescopic member 3223 to store elastic potential energy and drive the wedge member 33 to retract into the inner cavity of the first shaft 12 until it is completely retracted into the inner cavity of the first shaft 12, making an unobstructed passage for the polar rolls. When the second shaft 22 completes the polar roll transfer and separates from the first shaft 12 along the second direction Y, the protrusion at the end of the second shaft 22 gradually disengages from the outer end of the push rod 31, and the axial thrust on the push rod 31 disappears. At this time, the elastic potential energy stored in the telescopic member 3223 is released, pushing the transmission rod 3222 to rotate in the opposite direction. This, through the connecting rod 321, drives the push rod 31 to reset, and simultaneously causes the wedge-shaped member 33 to extend outward from the first shaft 12. At this time, the wedge-shaped member 33 protrudes from the surface of the first shaft 12, forming a limiting space with the first frame 11 for the pole roll on the first shaft 12, preventing the pole roll from falling off the free end of the first shaft 12.

[0078] In some embodiments, the electrode roll transport and storage device further includes a first rolling element 14, which includes multiple sets of first rolling elements 14, which are spaced apart along the second direction Y on the first shaft 12, each set of first rolling elements 14 including multiple elements, and the multiple first rolling elements 14 are spaced apart along the circumferential direction of the first shaft 12; and / or, it further includes a second rolling element 25, which includes multiple sets of second rolling elements 25, which are spaced apart along the second direction Y on the second shaft 22, each set of second rolling elements 25 including multiple elements, and the multiple second rolling elements 25 are spaced apart along the circumferential direction of the second shaft 22.

[0079] In this embodiment, the electrode roll transport and storage device further includes multiple sets of first rolling elements 14. Exemplarily, the first rolling elements 14 are balls or miniature rollers. The multiple sets of first rolling elements 14 are spaced apart along the second direction Y on the surface of the first shaft 12 by an embedded mounting method. Each set of first rolling elements 14 includes multiple elements, and the multiple first rolling elements 14 are distributed circumferentially along the first shaft 12. Specifically, during installation, an annular groove can be machined along the circumferential direction of the first shaft 12, and the first rolling elements 14 are assembled within the annular groove using a retainer, ensuring that a portion of the first rolling element 14 protrudes from the surface of the first shaft 12 to form a rolling contact surface.

[0080] In other embodiments, the electrode transport and storage device further includes multiple sets of second rolling elements 25. Exemplarily, the second rolling elements 25 are balls or miniature rollers. Multiple sets of second rolling elements 25 are spaced apart along the second direction Y on the surface of the second shaft 22 by an embedded mounting method. Each set of second rolling elements 25 includes multiple elements, which are distributed circumferentially along the second shaft 22. Specifically, during installation, an annular groove can be machined along the circumference of the second shaft 22, and the second rolling elements 25 are assembled within the annular groove using a retainer, ensuring that a portion of the second rolling element 25 protrudes from the surface of the second shaft 22 to form a rolling contact surface.

[0081] It should be noted that when the electrode roll moves on the first shaft 12 or the second shaft 22, the first rolling element 14 or the second rolling element 25 can convert the sliding friction between the electrode roll and the first shaft 12 or the second shaft 22 into rolling friction, which facilitates the smooth movement of the electrode roll by the pushing mechanism 23. At the same time, it also reduces the friction loss caused by the direct contact between the inner wall of the electrode roll and the first shaft 12 and the second shaft 22, thus extending the service life of the equipment.

[0082] For example, along the second direction Y, five sets of first rolling elements 14 can be spaced apart on the surface of the first shaft 12, each set of first rolling elements 14 including four, and the four first rolling elements 14 are spaced at the same angle along the circumferential direction of the first shaft 12.

[0083] Similarly, along the second direction Y, six sets of second rolling elements 25 can be arranged at equal intervals on the surface of the second shaft 22. Each set of second rolling elements 25 includes five elements, and the five second rolling elements 25 are arranged at equal angular intervals along the circumference of the second shaft 22.

[0084] In this embodiment of the application, there are no restrictions on the specific number of the first rolling element 14 and the second rolling element 25. In practical applications, technicians can set the specific number of the first rolling element 14 and the second rolling element 25 as needed.

[0085] In some embodiments, the electrode roll transport and storage device further includes a sensor 4 and a display 5. The sensor 4 is disposed on the side wall of the first shaft 12 and is used to monitor the number of electrode rolls on the first shaft 12. The display 5 is electrically connected to the sensor 4 and is connected to the frame. The display 5 switches different colors according to the number of electrode rolls.

[0086] In this embodiment, the electrode roll transport and storage equipment also includes a sensor 4 and a display 5. The sensor 4, which is a photoelectric or ultrasonic distance measuring device, is installed on the side wall of the first shaft 12 to monitor the number of electrode rolls stacked on the first shaft 12 in real time. The display 5 is a tri-color LED indicator or an industrial-grade digital tube display, which is electrically connected to the sensor 4 and installed in a prominent position on the first frame 11.

[0087] In practical applications, when sensor 4 detects no electrode rolls on the first shaft 12, display 5 shows a green light signal, indicating to the operator that electrode roll storage work can continue. When sensor 4 detects the presence of electrode rolls but not yet at full capacity, display 5 shows a yellow light signal, indicating to the operator that electrode roll storage work can continue but is nearing full capacity. When sensor 4 detects that the number of electrode rolls on the first shaft 12 has reached the rated capacity, display 5 shows a red light signal, indicating to the operator that electrode roll storage work should not be performed.

[0088] During operation, sensor 4 continuously transmits detection signals to the first axis 12, calculating the number of stacked pole rolls on the first axis by receiving signals reflected from the pole roll end face. The detection data is transmitted in real-time to the control unit of display 5, and after signal processing, drives the corresponding color indicator light on display 5 to illuminate. This design allows operators to quickly grasp the storage location status from a distance through color changes: green indicates normal storage, yellow indicates nearing full capacity, and red prohibits further storage and requires timely relocation. This achieves real-time visual monitoring of the storage location status, reducing the workload of manual inspections.
