Description

Technical Field

[0001] This utility model belongs to the technical field of battery production equipment, specifically relating to an air-suspension placement rack. Background Technology

[0002] Electrode rolling is a key process in lithium-ion battery manufacturing. By rolling the current collector coated with active material, the electrode surface density and the bonding force between materials can be improved. The binder firmly adheres the electrode material to the current collector, thereby optimizing the battery energy density and cycle performance, and preventing the electrode material from falling off the surface of the current collector during the cycle, which would cause energy loss in the battery.

[0003] Currently, electrode rolling is mainly carried out by rolling mills. The essential component of the rolling mill is the roller, which presses the electrode thinner and controls the thickness within a preset range. However, rollers are prone to wear after prolonged use. To ensure rolling accuracy, the rollers need regular maintenance and cleaning. This is mainly achieved by unloading the rollers from a trolley during disassembly. The unloaded rollers are then transferred to a placement rack, where they are placed for maintenance and cleaning. The placement rack typically uses wooden supports or square tube supports.

[0004] However, the transfer of rolls from the unloading trolley to the placement rack typically requires the use of an overhead crane for hoisting. The large weight of the rolls makes precise control during hoisting difficult, resulting in a complex and dangerous process. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides an air-suspension placement frame. The inner side of the skirt air cushion is inflated, forming an air chamber between the frame and the ground to lift the frame. The frame can be easily pushed to the unloading trolley, where inflation stops. The frame supports the rolls unloaded by the unloading trolley. The roll unloading operation does not require precise positioning using an overhead crane, which improves the convenience and safety of the roll unloading operation.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] This utility model provides an air-suspension placement frame, including a frame body with multiple frames, forming an unloading area between the multiple frames for parking and unloading rolls. During roll unloading, the multiple frames support the rolls. An air-suspension structure is also provided on the frame body. The air-suspension structure includes a skirt air cushion and a pressure control component for inflating the inner side of the skirt air cushion. The skirt air cushion is located at the bottom of the frame body. When the inner side of the skirt air cushion is inflated, an air chamber is formed between the frame body and the ground to lift the frame body.

[0008] In some implementations, the frame includes a base plate, the skirt air cushion is disposed on the base plate, the base plate includes a load-bearing part, and the inner side of the skirt air cushion stops inflating to allow the load-bearing part to descend to the ground.

[0009] In some implementations, the skirt air cushion is arranged in a ring around the perimeter of the load-bearing part.

[0010] In some implementations, the air pressure control component includes an air nozzle disposed on the frame and connected to the skirt air cushion.

[0011] In some implementations, the air pressure control assembly further includes a detection element for detecting the air pressure inside the skirt air cushion, the detection element being disposed on the frame.

[0012] In some implementations, the skirt air cushion is bonded to the frame.

[0013] In some implementations, a crossbeam for positioning the frame is erected between the frames, and the crossbeam spans between the frames.

[0014] In some implementations, the frame is provided with hook plates, and the crossbeam overlaps with the hook plates.

[0015] In some implementations, the frame is provided with a support for supporting the rolls.

[0016] In some implementations, the support base has a support groove for placing the roll, and the support groove is adapted to the roll.

[0017] In summary, this utility model has at least the following advantages:

[0018] The air-suspension placement frame provided by this utility model allows for precise control of the roll during unloading. An air pressure control component inflates the inner side of the skirt air cushion, creating an air chamber between the frame and the ground to elevate the frame. This suspension reduces friction with the ground. When the frame is pushed, it can be easily moved to the unloading trolley, which is located within the unloading area. Once the frame is positioned and the air pressure control component stops supplying air to the skirt air cushion, the frame descends to its original position. The unloading trolley then drives the roll down onto the frame, and the trolley leaves the unloading area. The frame supports the roll, completing the unloading operation. Compared to traditional hoisting methods for unloading rolls, the movable frame facilitates more precise control and solves the problems of inconvenience and safety risks associated with unloading heavy rolls.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figures 1-4 The air-suspension placement frame of this utility model can serve as a temporary carrier for placing the roll system during roll system maintenance and replacement, and can be used in conjunction with the roll unloading trolley 3 to improve the convenience and safety of the roll unloading operation of the roll 4.

[0030] Please see Figure 1The air-suspension placement frame includes multiple frames 1, and an unloading area 11 is formed between the multiple frames 1 for parking and unloading the unloading trolley 3. When unloading the roll 4, the multiple frames 1 support the roll 4. In some specific embodiments, there may be two frames 1. The two frames 1 are respectively moved to the two ends of the roll 4 along the axial direction to support the ends of the roll 4. After unloading the roll, the unloading trolley 3 can exit the unloading area 11 through the frames 1 along the distribution direction of the two frames 1.

[0031] Please combine Figures 2-4 The frame 1 is equipped with an air suspension structure 2. Specifically, the air suspension structure 2 can be symmetrically arranged to maintain the balance of the frame 1. The air suspension structure 2 includes a skirt air cushion 21 and a pressure control component 22 for inflating the inside of the skirt air cushion 21. The skirt air cushion 21 is located at the bottom of the frame 1. When the pressure control component 22 injects compressed air into the inside of the skirt air cushion 21, an air chamber 16 is formed between the frame 1 and the ground, which is equivalent to forming a high-pressure air film. The air chamber 16 suspends the frame 1, thereby reducing friction and allowing the frame 1 to be moved easily. When the pressure control component 22 stops supplying air to the inside of the skirt air cushion 21, the air chamber 16 is deflated, allowing the frame 1 to descend and return to its original position.

[0032] When roll 4 is unloaded onto the frame 1, the air suspension structure 2 first inflates the inside of the skirt air cushion 21. The air chamber 16 formed between the frame 1 and the ground lifts the frame 1, pushing it to the roll unloading trolley 3. The alignment of the roll unloading trolley 3 and the frame 1 is manually observed. Once the frame 1 is in the correct position, the air suspension structure 2 stops inflating the inside of the skirt air cushion 21, and the frame 1 descends. Subsequently, the roll unloading trolley drives roll 4 to descend, and roll 4 falls onto the frame 1. The frame 1 supports both ends of roll 4, and the roll unloading trolley 3 smoothly completes the roll unloading operation.

[0033] The frame 1, through the air suspension structure 2, is conducive to improving the flexibility of movement. When the air pressure control component 22 introduces compressed air into the inner side of the skirt air cushion 21, an air chamber 16 is formed between the frame 1 and the ground to lift the frame 1 and achieve the effect of air suspension. The friction between the frame 1 and the ground is reduced. When the pressure is constant and the friction coefficient is reduced, the friction resistance can be effectively reduced, and the manual power supply and steering functions can be realized.

[0034] In the traditional operation of unloading roll 4 by overhead crane, especially in the process of unloading roll 4 which is relatively heavy, a large overhead crane or two cranes are usually used for hoisting. The unloading operation is cumbersome, and there is a risk of roll 4 falling from a height due to the reliance on overhead crane equipment for unloading.

[0035] Compared to traditional overhead crane roll unloading methods, the air-suspension placement frame has a simpler structure and lower cost. If the roll system of roll 4 is too heavy, the air supply to the inner side of the skirt air cushion 21 stops to drive the frame 1 to descend. This effectively reduces the possibility of overload damage to the heavy-duty wheels when using heavy-duty wheels or other components on the frame 1, which could lead to serious safety accidents such as the frame 1 overturning. Specifically, the skirt air cushion 21 adjusts the gas pressure in the air chamber 16 through the air pressure control component 22, allowing the frame 1 to move the roll 4.

[0036] Example 2:

[0037] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the air suspension structure 2 of this utility model. Please refer to [link / reference]. Figures 2-4 .

[0038] Please see Figure 2 In this embodiment, the air pressure control component 22 includes an air nozzle 221, which is disposed on the frame 1 and communicates with the inner side of the skirt air cushion 21. Specifically, the frame 1 may have a fixing hole, and the air nozzle 221 passes through the fixing hole and is connected to the frame 1. Furthermore, multiple air nozzles 221 are provided, and the multiple air nozzles 221 are spaced apart, which can accelerate the inflation efficiency of the inner side of the skirt air cushion 21.

[0039] Please see Figure 3 and Figure 4 In a preferred embodiment, the frame 1 includes a base plate 12. Specifically, an air nozzle 221 is disposed on the base plate 12. The base plate 12 includes a load-bearing part 121. When the air pressure control component 22 controls the inner side of the skirt air cushion 21 to stop inflating, the load-bearing part 121 descends to the ground, which helps to improve the stability of the frame 1 when bearing weight. In some specific embodiments, the skirt air cushion 21 is arranged in a ring around the load-bearing part 121, that is, the skirt air cushion 21 forms an annular airbag on the outer side of the load-bearing part 121. When the air pressure control component 22 inflates the inner side of the skirt air cushion 21, the air chamber 16 formed by the load-bearing part 121 and the ground can raise the load-bearing part 121 to a height of 5mm above the ground. When the air pressure control component 22 controls the skirt air cushion 21 to deflate, the load-bearing part 121 descends and bears force. The skirt air cushion 21 is ring-shaped, which helps to maintain the balance and stability of the skirt air cushion 21. Specifically, multiple air nozzles 221 can be arranged in a ring around the load-bearing part 121 to improve the balance of the frame 1 during lifting.

[0040] Please see Figure 2 In some specific embodiments, the air pressure control component 22 also includes a detection element 222 for detecting the air pressure inside the skirt air cushion 21. The detection element 222 is preferably, but not limited to, a pressure gauge. When the air nozzle 221 is connected to an external air pump for inflation, the pressure gauge can detect the air pressure inside the skirt air cushion 21, thereby controlling the height of the frame 1, which is convenient to use.

[0041] In a preferred embodiment, the skirt air cushion 21 is bonded to the frame 1 with an adhesive. When the skirt air cushion 21 needs to be replaced, the adhesive can be dissolved with a solvent, the skirt air cushion 21 can be removed and replaced.

[0042] Example 3:

[0043] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the frame 1 of this utility model. Please refer to [link / reference]. Figure 5 .

[0044] In this utility model, a crossbeam 13 for positioning the frame 1 is erected between the frame bodies 1. The crossbeam 13 spans between the frame bodies 1. In some specific embodiments, the frame body 1 includes a support column, and a hook plate 14 is provided on the support column. The crossbeam 13 overlaps with the hook plate 14. After the frame body 1 is aligned with the unloading roller trolley 3, the crossbeam 13 is clamped between the two frame bodies 1. The crossbeam 13 can restrict the movement of the frame body 1 and improve the stability of the frame body 1.

[0045] In a preferred embodiment, the frame 1 includes a support seat 15, on which a support groove 151 is formed. The support groove 151 is adapted to the roll 4. Specifically, the support groove 151 is an arc-shaped groove. Furthermore, the support seat 15 can be made of soft rubber, such as urethane rubber, which helps to protect the roll 4 and reduces the possibility of minor collisions between the roll 4 and the support seat 15 during roll unloading, thus reducing surface damage to the roll 4. The support seat 15 is provided with a deformation groove, specifically a rectangular groove. The support seat 15 can adapt to roll systems of different sizes of roll 4, improving the flexibility of use.
