Technical Field

[0001] The utility model belongs to the technical field of transportation devices, and particularly relates to a pole roll transportation device. Background Art

[0002] Pole rolls are usually important components in battery production, and extremely high quality requirements are imposed on them. Especially for battery components that are vulnerable to environmental influences (such as moisture, oxidation, etc.), since it is known that the previous process pole pieces of the battery and the assembly workshop are not in the same production environment, if the pole pieces are not protected after production, there is a risk of pole piece water absorption during transportation, resulting in the scrapping of the battery pole pieces. Therefore, using a dedicated transportation device can effectively protect its quality and avoid product damage or performance degradation caused by external environmental influences.

[0003] Under the current technical background, the transportation device usually includes a box body provided with a vacuum environment for carrying pole rolls. However, the connection of the box body to the pole roll mainly depends on a single steel pipe fixedly connected to the box body. Therefore, when the box body is subjected to an external force collision, its stability guarantee for the pole roll is limited, that is, the pole roll will fall off or shake along with the box body, and it is difficult to fully ensure its safety during transportation.

[0004] Based on this, it is urgent to improve the existing pole roll transportation device to solve the defects existing in the above-mentioned technology. Summary of the Utility Model

This design not only enhances the support strength of the cantilever but also effectively prevents the pole roll from falling off or shaking during transportation. Even when the box body is subjected to an external force collision, the stability and safety of the pole roll can be ensured, greatly reducing the damage or scrapping of the pole roll caused by the external environment or collision.

Therefore, the protection scope of the present application should be determined by the scope defined by the claims of the present application.

[0048] The following will further describe the present utility model in detail in conjunction with specific embodiments, but the embodiments of the present utility model are not limited thereto.

[0049] Embodiment 1

[0050] As Figure 1 shown, the present application divides the pole coil transportation device into a cantilever frame 1 for receiving the pole coil and a box body 2 for receiving the cantilever frame 1. Specifically, this embodiment relates to a pole coil transportation device 22, including a cantilever frame 1 and a box body 2 for assembling the cantilever frame 1. The cantilever frame 1 includes a main frame 11 and cantilevers 12 spaced along the height direction of the main frame 11. The cantilever 12 is provided with an anti-detachment pin 121 to prevent the assembled pole coil from falling off.

[0051] It is known that during the battery production process, the positive and negative electrode strips are usually wound into battery electrode rolls according to established rules. Since the electrode rolls are relatively large in size and heavy in weight, they are prone to deformation or damage under external forces during transportation, which in turn has an adverse impact on the overall performance and safety of the battery. To solve this problem, this application proposes an improved solution, that is, the existing device for receiving the electrode roll is firmly installed on a stable main frame 11. For the design of the main frame 11, this application decides to directly design the bottom of the main frame 11 as a quadrilateral or other stable shape. Through the main frame 11 involved in this embodiment, its shape can be directly and closely attached to the inner side of the box body 2, which not only improves the space utilization rate of the box body 2, but also significantly reduces various safety risks caused by shaking due to the close fit with the box body 2, ensuring the stability and safety of the battery electrode roll during transportation.

[0052] Furthermore, in this embodiment, there are two main ways to set the anti-detachment pin 121: one is to set it on both sides of the cantilever 12 far from the main frame 11, and the other is to set it on any one side of the cantilever 12 far from the main frame 11 (as Figure 2 shown). In the first way, when the anti-detachment pin 121 is located on both sides of the cantilever 12 and far from the main frame 11, the main function of the main frame 11 is to support the electrode roll on both cantilevers 12. This design aims to make full use of the space layout of the box body 2 to assemble the electrode roll with the largest volume. In the second way, the anti-detachment pin 121 is only set on one side of the cantilever 12 and far from the main frame 11. At this time, the main frame 11 is responsible for supporting the electrode roll on this side of the cantilever 12 to achieve the effective transportation of the small-volume electrode roll.

[0053] In the specific implementation, in reality, the electrode rolls generally have different width specifications according to different application scenarios. Therefore, in order to improve the flexibility and adaptability of the cantilever 12, this embodiment designs a plurality of assembly holes on the cantilever 12 that can fix the anti-detachment pin 121. These assembly holes can adjust the position of the anti-detachment pin 121 in the cantilever 12 (i.e., corresponding to different assembly holes), so that the cantilever 12 can be precisely adjusted according to the size and shape of the electrode roll, thereby realizing the stable clamping of various-width electrode rolls. This move aims to prevent the electrode roll from falling off due to shaking during transportation, thereby significantly improving the transportation safety of the battery electrode roll.

[0054] Furthermore, as Figure 3 shown, the cantilever 12 is divided into a receiving part 122 for receiving the electrode roll, an assembly part 123 for assembling the anti-detachment pin 121, and a connecting part 124 connected to the main frame 11; among them, as Figure 4The anti-slip pins 121 shown are vertically arranged on the assembly part 123, and the anti-slip pins 121 are arranged on both sides of the mounting part in the thickness direction. This design is intended to ensure that when the pole coil is wound on the cantilever 12 of this embodiment, its position can be kept constant to avoid deviation. In a specific embodiment, if the pole coil is arranged on only one side in the thickness direction of the cantilever 12, the lower part of the cantilever 12 may still shake during transportation. However, through the optimization of the setting of the anti-slip pins 121 in this embodiment, after the pole coil is wound, its upper and lower parts can be firmly clamped by the anti-slip pins 121, thereby significantly improving its stability.

[0055] Preferably, Figure 4 As shown, the connection part 124 is passed through the inner frame 111 of the main frame 11, and the inner frame 111 is cross-set at the position where the connection part 124 passes through. Among them, the connection part 124 not only bears the weight of the cantilever 12, but also needs to ensure the stability of the cantilever 12 in the main frame 11. Therefore, this embodiment chooses a connection method that passes through the inner frame 111. The design of the inner frame 111 fully considers the stability of the structure and the convenience of use. It is cross-set at the position where the connection part 124 passes through, forming a stable support structure. Such a design enables the cantilever 12 to effectively disperse the force and reduce stress concentration when subjected to external force, thereby improving the durability and safety of the entire equipment.

[0056] Implementation Method 2

[0057] like Figures 1-5 As shown, the difference from the first embodiment is that in order to further improve the bearing capacity and stability of the main frame 11 of the present application to the pole coil, the main frame 11 in the present embodiment is provided with a base 112 and a stand 113 vertically arranged on the base 112. The stand 113 is fixed by a plurality of reinforcing ribs 114 connected to the base 112.

[0058] In view of the actual demand for current pole coil transportation, the weight of a pole coil transported in a single trip may exceed 200KG. If this weight encounters an impact during transportation, the internal pole coil will generate a strong impact force on the main frame 11 due to gravity, which may cause the structure of the main frame 11 to be damaged or even disintegrated. Therefore, this embodiment particularly introduces a reinforcing rib 114 at the connection between the base 112 and the stand 113 to ensure that the stand 113 and the base 112 can still maintain a stable connection angle when subjected to external impact, thereby effectively preventing the risk of structural damage and improving the overall stability.

[0059] Further, in this embodiment, the cantilever 12 is designed as a metal tube with an outer diameter R of 50 - 70 mm and a wall thickness L ≥ 6 mm. In a specific embodiment, the outer diameter R of the cantilever 12 can be: 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 59 mm, 60 mm, 61 mm, 62 mm, 63 mm, 64 mm, 65 mm, 66 mm, 67 mm, 68 mm, 69 mm, 70 mm; the wall thickness L of the cantilever 12 is preferably 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc. Within these preferred value ranges, the strength, rigidity, and durability in practical applications are fully considered.

[0060] Among them, the larger outer diameter R ensures that the cantilever 12 is not easily deformed when bearing heavy loads, and the sufficient wall thickness L enhances its compressive resistance and impact resistance. This design enables the cantilever 12 to maintain stable performance in various complex environments. In addition, in this embodiment, in addition to stainless steel and ordinary square steel pipes, high-strength and corrosion-resistant alloy steel can also be used as the main material of the cantilever 12. This material not only has excellent mechanical properties but also can be used for a long time in a harsh environment without being easily damaged.

[0061] Other parts identical to Embodiment 1 are not described again in this embodiment.

[0062] Embodiment 3

[0063] As Figure 1 shown, different from Embodiment 1: In order to further improve the stability during the transportation of the electrode roll, the box body 2 includes a sealing door 21 for sealing the box body 2, a transportation device 22 for realizing the transportation and movement of the box body 2, and a pressure control device 23 provided on one side of the box body 2.

[0064] Specifically, the design of the sealing door 21 of the sealed box body 2 ensures that the battery electrode roll can be completely isolated from the external environment during transportation, preventing adverse effects on the battery electrode roll caused by the intrusion of external humidity, dust, or other pollutants. The sealing door 21 is made of high-strength and wear-resistant materials and is equipped with a reliable sealing strip to ensure that the inside and outside of the box body 2 are completely isolated when it is in the closed state.

[0065] Furthermore, the setting of the pressure control device 23 is the key to realizing the control of the air pressure of the electrode roll transported in the box body 2 in this embodiment. During the transportation of the battery electrode roll, due to changes in factors such as the environment and temperature, the air pressure inside the box body 2 may change, which may have an adverse impact on the performance and safety of the battery electrode roll. Therefore, in this embodiment, a pressure control device 23 is particularly provided on one side of the box body 2 to ensure that it remains in a stable state throughout the transportation process by automatically adjusting the air pressure inside the box body 2. In a specific embodiment, the controlled end of the pressure control device 23 includes a control valve electrically connected to the nitrogen port, and the control valve controls the inflow and stop of nitrogen, which ensures the precise control of the air pressure inside the box body 2.

[0066] Specifically, the pressure control device 23 can also be equipped with a high-precision air pressure sensor to real-time monitor the change of the air pressure inside the box body 2 and feedback the data to the control system (various existing control systems that can collect and process the information collected by sensors). The control system automatically adjusts the opening degree of the control valve according to the preset air pressure range and the current air pressure value, so as to realize the precise control of the air pressure inside the box body 2. This design not only ensures the safety and stability of the battery electrode roll during transportation, but also effectively extends its service life.

[0067] Furthermore, the pressure control device 23 includes a pressure display device for displaying the nitrogen pressure inside the box body 2. This design enables the operator to intuitively understand the air pressure state inside the box body 2, so as to make corresponding adjustments according to the actual situation. In addition, the pressure display device can also be connected to the control system to realize the real-time transmission and monitoring of data, further improving the intelligence level of the system.

[0068] On the basis of Embodiment 3, in order to further improve the transportation efficiency and safety of the battery electrode roll, the structure and material of the box body 2 are optimized in this embodiment. First, in a specific embodiment, the box body 2 can be made of a lightweight and high-strength composite material, which not only has excellent compressive and impact resistance performance, but also has good heat insulation and sound insulation effects, and can effectively protect the battery electrode roll from the influence of the external environment.

[0069] In summary, in this embodiment, by introducing the pressure control device 23, optimizing the structure and material of the box body 2, strengthening the sealing performance, and setting up special fixing and protection devices, etc., the stability and safety of the battery electrode roll during transportation are significantly improved.

[0070] For those that are the same as Embodiment 1, they will not be elaborated in this embodiment.

[0071] Embodiment 4

[0072] Such as Figures 1-6As shown, different from Embodiment 1, as a further improvement to the pole roll transportation device 22 of the present utility model, the box body 2 has two switchable sealed doors 21, and the sealed doors 21 correspond to the cantilevers 12 provided at the front and rear ends of the main body frame 11. The advantage of this design is that it greatly improves the convenience and efficiency of operation. When loading or unloading battery pole rolls, the operator can open the two sealed doors 21 simultaneously, thus quickly and conveniently completing the placement or removal of the pole rolls, greatly saving time. At the same time, due to the corresponding position design of the two sealed doors 21 and the cantilevers 12, it can be ensured that when opening or closing the sealed doors 21, no interference or damage will be caused to the cantilevers 12, ensuring the stability and safety of the entire transportation device 22.

[0073] In addition, the two switchable sealed doors 21 also enable better utilization of the space inside the box body 2. When loading battery pole rolls, the operator can open one or both of the sealed doors 21 according to needs, and place the pole rolls into the box body 2 from the corresponding positions, thus achieving full utilization of the space inside the box body 2 and improving the transportation efficiency.

[0074] Preferably, the transportation device 22 includes casters 221 provided at the bottom of the box body 2; and / or a fork slot 222 for the hydraulic forklift to fork. Specifically, the casters 221 are more suitable for short-distance transportation, and the operator can easily push the box body 2 to move; while the design of the fork slot 222 is more suitable for long-distance transportation, and the hydraulic forklift can directly lift the box body 2 and transport it to the designated position, greatly improving the transportation efficiency and safety.

[0075] Furthermore, the box body 2 is also provided with an observation window 24 to facilitate observing the state of the battery pole rolls inside the box body 2 without opening the sealed doors 21.

[0076] Based on the descriptions of the above Embodiments 1-3, this embodiment will further refine the specific operation process of the embodiment:

[0077] S1. Preparation stage: To ensure that the overall airtightness of the sealed box body 2 meets the standards, after assembling the cantilever frame 1 for carrying the pole rolls, it is necessary to check the integrity of the sealed doors 21 to ensure that there are no signs of damage. At the same time, a comprehensive performance evaluation should be carried out on the operating status of the electric or hydraulic drive wheel system to confirm its normal operation and eliminate the possibility of abnormal noise and jamming. The air pressure sensor and control valve in the pressure control device 23 also need to be calibrated to ensure its stable operation, and the readings of the pressure display device should be accurate, so as to ensure high stability and safety during transportation.

[0078] S2. Loading the battery pole coil: The staff winds the battery pole coil that has been slit onto the cantilever 12 inside the sealed box, ensuring that the battery pole coil is stable and does not shift. Then close the sealing door 21 and confirm that it is fully closed and locked to ensure that the external environment will not cause any potential impact on the inside of the box body 2.

[0079] S3. Pressure control process: During the pressure control operation, first start the nitrogen supply port to ensure that nitrogen can smoothly enter the inside of the sealed box body 2. During the nitrogen filling process, the air pressure sensor built in the pressure control device 23 will continuously and accurately monitor the dynamic change of the air pressure inside the box body 2. Once the air pressure reaches the preset safety value, the control valve in the pressure control device 23 will automatically close according to the preset parameters, thus terminating the further filling of nitrogen. In addition, for the convenience of the staff to grasp the air pressure state inside the box body 2 in real time, the pressure display device will clearly display the nitrogen pressure value inside the current box body 2.

[0080] S4. Transportation stage: For long-distance transportation tasks, in this embodiment, a fork position for using a hydraulic forklift is provided. The hydraulic forklift can accurately insert into the fork position at the bottom of the box body 2 and, relying on the hydraulic forklift, transport the box body 2 to the destination efficiently and stably.

[0081] For short-distance transportation requirements, the staff can directly operate and quickly and conveniently transport by pushing the caster 221 at the bottom of the box body 2.

[0082] It is worth mentioning that to ensure the safety and stability of the box body 2 during transportation, this embodiment introduces the pressure control device 23. During the entire transportation process, this device will continuously monitor the air pressure change inside the box body 2 and automatically and accurately adjust the opening degree of the control valve according to the actual situation, so as to ensure that the air pressure always remains stable.

[0083] For those that are the same as those in Embodiment 1, they will not be elaborated in this embodiment.

[0084] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
