[0038] Please refer to Figure 1 、 Figure 2In an embodiment of the present application, the lithium film carrying device comprises a walking mechanism 100, a vertical column 200 and a lithium film lifting mechanism 300.

The walking mechanism 100 can drive the lithium film lifting mechanism 300 carrying the lithium film to walk.

[0039] In an embodiment, a lithium film carrying device is provided, which comprises a walking mechanism 100, a vertical column 200 and a lithium film lifting mechanism 300. The walking mechanism 100 is used to provide the moving ability of the whole device, the vertical column 200 is mounted on the mounting position of the walking mechanism 100 and extends upward in the vertical direction, and the lithium film lifting mechanism 300 is mounted on the vertical column 200 and can be lifted along the vertical column 200.

[0040] Specifically, the walking mechanism 100 is provided with a mounting position for fixing the vertical column 200. After the vertical column 200 is mounted on the mounting position, it extends upward in the vertical direction to form a vertical guide rail structure. The lithium film lifting mechanism 300 is mounted on the vertical column 200 and can be lifted along the vertical column 200. This structure design enables the lithium film lifting mechanism 300 to carry the lithium film to be lifted to be lifted along the vertical column 200, thereby realizing the position adjustment of the lithium film in the vertical direction.

[0041] In the embodiment, the walking mechanism 100 can drive the lithium film lifting mechanism 300 carrying the lithium film to walk. Through the driving of the walking mechanism 100, the whole lithium film carrying device can move in the horizontal direction, thereby realizing the horizontal carrying of the lithium film from one position to another position. In combination with the lifting function of the lithium film lifting mechanism 300, the device can realize the flexible carrying of the lithium film in the three-dimensional space.

[0042] In an embodiment, the walking mechanism 100 can adopt an electric wheel type structure, which comprises a chassis, a driving motor and a walking wheel 120. The driving motor is mounted on the chassis and connected with the walking wheel 120 through a transmission mechanism to drive the walking wheel 120 to rotate, thereby driving the whole device to walk. The mounting position on the chassis can be designed as a reinforcing rib structure to enhance the stability of the installation of the vertical column 200. This walking mechanism 100 has a simple structure, flexible movement and convenient operation and control.

[0043] In another embodiment, the walking mechanism 100 can adopt a tracked structure, including a chassis, a driving device, and a track assembly. The track assembly is installed on both sides of the chassis and is driven to operate by the driving device, realizing the walking of the device. This structure is suitable for uneven ground working environment, with better adaptability and stability.

[0044] In an embodiment, the column 200 can adopt a single column structure, and the surface of the column is provided with a guide rail. The lithium film lifting mechanism 300 is connected with the column 200 through a slider matched with the guide rail, realizing the lifting movement along the column 200. This structure is simple, occupies small space, and is suitable for the carrying of light lithium film.

[0045] In another embodiment, the column 200 can adopt a double-column structure, and two columns are arranged in parallel and connected through a cross beam to form a stable frame structure. The lithium film lifting mechanism 300 is installed between the two columns and lifted along the column through a lifting mechanism. This structure has good stability and strong carrying capacity, and is suitable for the carrying of heavy lithium film.

[0046] In an embodiment, the lithium film lifting mechanism 300 can include a lifting platform and a lifting driving device. The lifting platform is used to place the lithium film, and the lifting driving device is responsible for driving the lifting platform to lift along the column 200. The lifting driving device can adopt the form of electric screw, hydraulic cylinder or air cylinder, and the appropriate driving mode is selected according to the actual needs.

[0047] In another embodiment, the lithium film lifting mechanism 300 can be designed as an adjustable structure, including a plurality of adjustable support arms and a tray. The support arm can be adjusted according to the size of the lithium film, and the surface of the tray is provided with anti-skid material to ensure that the lithium film does not slip during the carrying process.

[0048] The lithium film carrying device of the present application realizes flexible carrying of lithium film through the combination of the walking mechanism 100, the column 200 and the lithium film lifting mechanism 300. The walking mechanism 100 provides the moving ability in the horizontal direction, and the lithium film lifting mechanism 300 can lift along the column 200, realizing the position adjustment in the vertical direction. This structure design makes the lithium film carrying device be able to independently complete the carrying work of lithium film, without relying on large production line, greatly reducing the cost and complexity of lithium film carrying.

[0049] In particular, the lithium film carrying device of the present application has simple structure and convenient operation, and is suitable for the carrying work of small batch lithium film. Compared with the traditional production line formed by a large number of devices or equipment, the device has obvious cost advantage and flexibility advantage. At the same time, the device can also be functionally expanded and structurally adjusted according to actual needs, to meet the lithium film carrying needs in different scenes.

[0050] In summary, the lithium film carrying device provided by the application realizes flexible carrying of the lithium film through the structural combination of the walking mechanism 100, the stand column 200 and the lithium film lifting mechanism 300. The walking mechanism 100 provides horizontal movement capability, and the lithium film lifting mechanism 300 can be adjusted in vertical position by lifting along the stand column 200, and the overall structure is simple and compact, and convenient to operate. Compared with the traditional production line formed by a large number of devices or equipment, the device is particularly suitable for small-batch carrying of the lithium film, effectively solves the technical problem of high installation cost when using the production line to carry a small amount of lithium film, and has obvious economic and practical advantages.

[0051] In the embodiment, the walking mechanism 100 is provided with a mounting position, the stand column 200 is mounted on the mounting position, the stand column 200 extends upward in the vertical direction, and the lithium film lifting mechanism 300 is mounted on the stand column 200 and can be lifted along the stand column 200 to carry the lithium film up and down along the stand column 200 when lifting the lithium film. The walking mechanism 100 can drive the lithium film lifting mechanism 300 carrying the lithium film to walk, so that the lithium film can be carried without forming a production line by a large number of devices or equipment in use, and the carrying function of a small amount of lithium film is realized, and the installation cost of the production line is reduced.

[0052] In an embodiment, the lithium film lifting mechanism 300 includes a lifting driving assembly 310, a connecting beam 320 and two lifting rods 330. The lifting driving assembly 310 is mounted on one side of the stand column 200 and can be lifted along the stand column 200. The connecting beam 320 is mounted on the lifting driving assembly 310 and extends in the horizontal direction so that both ends thereof are located outside the stand column 200. The connecting beam 320 has a connecting position at each end, and the two lifting rods 330 are respectively mounted on the connecting positions and extend away from the stand column 200. The top of each of the two lifting rods 330 is provided with a lifting groove 340 for lifting the lithium film.

[0053] In the embodiment, the lithium film lifting mechanism 300 realizes lifting and lifting of the lithium film through the cooperation of the lifting driving assembly 310, the connecting beam 320 and the two lifting rods 330. The lifting driving assembly 310 is mounted on one side of the stand column 200 and can be in the form of a gear and rack mechanism, a chain transmission mechanism or a hydraulic driving mechanism driven by a motor. The main function is to provide power for lifting along the stand column 200. The lifting driving assembly 310 can stably move up and down along the stand column 200, thereby driving the entire lithium film lifting mechanism 300 to adjust the position in the vertical direction.

[0054] The connecting beam 320 is mounted on the lifting driving assembly 310 and extends horizontally with both ends located outside the upright column 200. The connecting beam 320 can be made of metal material with sufficient strength and rigidity to withstand the weight of the lithium film without significant deformation. The two ends of the connecting beam 320 are respectively formed with connecting sites which can be structures formed by welding, bolting or other fixing methods for mounting the lifting rods 330.

[0055] The two lifting rods 330 are respectively mounted on the connecting sites at the two ends of the connecting beam 320 and extend towards the side away from the upright column 200. The lifting rods 330 can be made of lightweight high-strength materials such as aluminum alloy or carbon fiber composite material to reduce the overall weight while ensuring sufficient strength. The top of each of the two lifting rods 330 is formed with a lifting groove 340 which is specially designed for lifting the lithium film. The shape and size of the lifting groove 340 match those of the lithium film to ensure that the lithium film can be stably placed thereon without slipping.

[0056] In actual application, when the lithium film needs to be transported, the operator can control the walking mechanism 100 to move the entire lithium film transporting device to the vicinity of the lithium film. Then, by controlling the lifting driving assembly 310, the lithium film lifting mechanism 300 is lowered to an appropriate height so that the lifting grooves 340 on the lifting rods 330 are located below the lithium film. Then, the operator can place the lithium film on the lifting grooves 340 of the two lifting rods 330, and the lithium film will be stably supported. Subsequently, the operator can control the lifting driving assembly 310 to raise the lithium film lifting mechanism 300 to lift the lithium film off the ground or workbench. Finally, the operator can control the walking mechanism 100 to move the entire device with the lifted lithium film to the target position, completing the transportation of the lithium film.

[0057] In another embodiment, the lifting grooves 340 can be made of special anti-slip materials or structures such as rubber pads, silicone layers or micro convex structures to increase the friction force of the contact surface with the lithium film, further preventing the lithium film from slipping or falling during transportation. In addition, the lifting grooves 340 can also be designed as adjustable width structures, and the distance between the two lifting rods 330 can be changed by adjusting mechanism to adapt to lithium films of different sizes, enhancing the applicability and flexibility of the device.

[0058] In yet another embodiment, the lifting driving assembly 310 can include a motor, a reducer and a transmission mechanism. The motor reduces the speed and increases the torque through the reducer, and then converts the rotary motion into linear motion along the upright column 200 through the transmission mechanism such as gear rack, chain wheel and chain or belt pulley and belt. In addition, the lifting driving assembly 310 can also be equipped with a brake device which can automatically lock the position when the power is stopped to prevent the lithium film lifting mechanism 300 from sliding down due to gravity, ensuring the safety of the transportation process.

[0059] In this embodiment, the structure design of the lithium film lifting mechanism 300 enables the lithium film to be stably lifted and operated. Two lifting rods 330 are located on both sides of the lithium film, forming a double fulcrum support for the lithium film, improving the stability of lifting. At the same time, the lifting rods 330 extend towards the side away from the column 200, so that the lithium film maintains a certain distance from the column 200, avoiding collision or friction during transportation, and protecting the lithium film from damage.

[0060] The walking mechanism 100 provides horizontal movement capability, while the lithium film lifting mechanism 300 is lifted along the column 200 by the lifting driving assembly 310, realizing vertical position adjustment. This movement capability in three-dimensional space enables the device to adapt to various complex transportation environments and tasks.

[0061] The advantages of this structure design are: first, through the cooperation of the lifting driving assembly 310 and the column 200, precise positioning of the lithium film in the vertical direction is realized; second, the combination structure of the connecting beam 320 and the two lifting rods 330 provides stable support for the lithium film, preventing the lithium film from deforming or being damaged during transportation; finally, the entire lithium film lifting mechanism 300 is simple in structure, convenient to operate, and low in maintenance cost, suitable for small-batch lithium film transportation work.

[0062] The lithium film lifting mechanism 300 in this embodiment realizes stable lifting and precise lifting of the lithium film through the cooperation of the lifting driving assembly 310, the connecting beam 320 and the two lifting rods 330. This structure design enables the lithium film transportation device to independently complete the transportation of the lithium film, without relying on large production lines, effectively solving the technical problem of high installation cost when using production lines for small amount of lithium film transportation. At the same time, the lifting grooves 340 on the two lifting rods 330 form a double fulcrum support for the lithium film, improving the stability and safety during transportation, avoiding the risk of damage to the lithium film, and further enhancing the practical value of the device.

[0063] In an embodiment, a clamping groove 350 is formed on the connecting position, and the lifting rod 330 is clamped in the clamping groove and bolted with the connecting beam 320.

[0064] Specifically, the connecting beam 320 has two ends, each of which forms a connecting position, and each connecting position has a clamping groove 350. The clamping groove 350 can be a groove structure formed on the connecting position, which shape and size match the one end of the lifting rod 330, so that the lifting rod 330 can be accurately clamped therein. The depth of the clamping groove 350 can be determined according to actual needs, which should be deep enough to ensure that the lifting rod 330 can be stably clamped inside, but not too deep to affect the overall strength of the connecting beam 320.

[0065] The lifting rod 330 is clamped in the clamping groove, and through this clamping mode, the lifting rod 330 and the connecting beam 320 form a preliminary positioning and fixing relationship. The clamping structure can prevent the lifting rod 330 from rotating or moving laterally during use, improving the stability of the lithium film lifting mechanism 300. In order to further enhance the firmness of the connection, the lifting rod 330 and the connecting beam 320 are also fixed by bolting.

[0066] Bolting can be achieved using fasteners such as bolts, screws, or pins. For example, corresponding screw holes can be pre-drilled on the clamping groove 350 and the lifting rod 330, and then the two are firmly connected together by bolts. The bolting method not only prevents the lifting rod 330 from falling out of the clamping groove 350, but also resists various stresses and torques that the lifting rod 330 may generate when carrying the lithium film, ensuring the reliability and safety of the entire lifting structure.

[0067] In actual application, the combination of clamping and bolting has multiple advantages. First, clamping provides quick positioning, allowing the lifting rod 330 to be accurately installed on the connecting beam 320, reducing the alignment time during installation. Second, bolting provides reliable fixing force, ensuring that the lifting rod 330 does not loosen or fall off during the lifting and movement of the lithium film. Finally, this connection method is easy to disassemble and maintain, and when the lifting rod 330 needs to be replaced or repaired, it can be easily removed by removing the bolting.

[0068] In a specific embodiment, the clamping groove 350 can adopt a dovetail groove structure, and the connecting end of the lifting rod 330 is correspondingly processed into a dovetail shape, so that the two can be tightly engaged. The dovetail groove structure has self-locking characteristics, which can provide constraint in both horizontal and vertical directions, further enhancing the stability of the connection. Bolting can use high-strength bolts that pass through the pre-drilled holes in the dovetail groove and the lifting rod 330, and are fastened by nuts to form a firm connection.

[0069] In another embodiment, the clamping groove 350 can be designed as a stepped structure, and the connecting end of the lifting rod 330 is correspondingly formed into a matching stepped shape. This structure not only provides good positioning function, but also increases the contact area, making the connection more stable. Bolting can use multiple small-diameter screws distributed at different positions of the stepped structure, evenly distributing the connection stress and improving the reliability of the connection.

[0070] In combination with the overall structure of the lithium film lifting mechanism 300, the lifting driving assembly 310 is installed on one side of the column 200 and can be lifted along the column 200, and the connecting beam 320 is installed on the lifting driving assembly 310 and extends in the horizontal direction, so that both ends thereof are located outside the column 200. The connecting sites at both ends of the connecting beam 320 are formed with clamping grooves 350, and two lifting rods 330 are clamped in one clamping groove 350 and bolted with the connecting beam 320. Both of the two lifting rods 330 extend towards the side away from the column 200, and the top thereof is formed with a lifting groove 340 for lifting the lithium film. This structure enables the lithium film lifting mechanism 300 to stably lift the lithium film and lift along the column 200 with the lifting driving assembly 310, thereby achieving the vertical position adjustment of the lithium film.

[0071] The clamping groove 350 combined with the bolted connection mode in the embodiment solves the technical problem of unstable connection between the lifting rod 330 and the connecting beam 320. During the lithium film carrying process, especially when the lithium film is heavy or the carrying device is accelerated, the connection between the lifting rod 330 and the connecting beam 320 will bear a large stress. If the connection is not firm, it may cause the lifting rod 330 to loosen, deform or even fall off, resulting in damage to the lithium film. The clamping groove 350 combined with the bolted connection mode can effectively resist forces and torques in various directions, ensuring that the lifting rod 330 is always stably connected to the connecting beam 320, thereby improving the safety and reliability of the lithium film carrying.

[0072] In addition, this connection mode also facilitates the installation, disassembly and replacement of the lifting rod 330. When the lifting rod 330 is worn or damaged, it can be quickly replaced, reducing maintenance time and cost. At the same time, since the standard clamping and bolted structure is adopted, it is also convenient to replace the lifting rod 330 of different shapes or sizes according to the needs of lithium films of different specifications, thereby enhancing the adaptability and flexibility of the lithium film carrying device.

[0073] In an embodiment, the connecting beam 320 includes a connecting section and two telescopic sections, the connecting section is connected with the lifting driving assembly 310, and the two telescopic sections are respectively arranged at both ends of the connecting section, and one end of each telescopic section away from the connecting section forms the connecting site.

[0074] Specifically, the connecting beam 320 adopts a segmented structure, including a connecting section in the middle and telescopic sections on both sides. The connecting section is the core part of the connecting beam 320 and is directly connected with the lifting driving assembly 310, responsible for transmitting the lifting movement generated by the lifting driving assembly 310 to the entire connecting beam 320 structure. The connecting section can be made of metal materials such as aluminum alloy and steel, which has sufficient strength and stiffness and can withstand the weight of the lithium film without significant deformation. The middle part of the connecting section can be provided with a reinforcing rib or a thickened area to enhance the strength of the connection with the lifting driving assembly 310.

[0075] Two telescopic segments are arranged at the two ends of the connecting segment, forming the left and right sides of the connecting beam 320. The main feature of the telescopic segment is that it can adjust the length relative to the connecting segment, that is, it can be lengthened or shortened, thereby changing the total length of the connecting beam 320. This telescopic function can be achieved by various structures, such as sleeve structure, gear and rack mechanism, threaded adjusting mechanism, etc. In the sleeve structure, the telescopic segment can include an inner sleeve and an outer sleeve, the inner sleeve can slide in the outer sleeve, and is fixed at the required position by a locking mechanism (such as a bolt, buckle, etc.). In the gear and rack mechanism, the telescopic segment can include a rod body with a rack and a base with a gear, the rack is moved by rotating the gear to achieve the telescopic function. In the threaded adjusting mechanism, the telescopic segment can include a rod body with external threads and a sleeve with internal threads, the telescopic function is achieved by rotating the rod body or the sleeve.

[0076] The end of each telescopic segment away from the connecting segment forms a connecting site for mounting the lifting rod 330. The connecting site can be designed as a platform, a seat body or a groove structure to facilitate the installation and fixation of the lifting rod 330. In some embodiments, a clamping groove 350 can be formed on the connecting site, and the lifting rod 330 is clamped in the clamping groove 350 and bolted with the connecting beam 320 to form a firm connection.

[0077] In actual application, when different widths of lithium film need to be transported, the operator can adjust the extension length of the two telescopic segments according to the width of the lithium film, so that the distance between the two lifting rods 330 matches the width of the lithium film. After adjustment, the telescopic segment is locked, and the total length of the connecting beam 320 is fixed. This adjustable connecting beam 320 structure greatly enhances the adaptability and flexibility of the lithium film transporting device, enabling it to adapt to various specifications of lithium film and improving the versatility of the device.

[0078] In a specific embodiment, the telescopic segment can adopt a sleeve structure, including an outer sleeve fixedly connected with the connecting segment and an inner sleeve capable of sliding in the outer sleeve. The outer end of the inner sleeve forms a connecting site for mounting the lifting rod 330. A plurality of locking holes are uniformly distributed along the length direction between the outer sleeve and the inner sleeve, and by inserting a locking pin into the corresponding locking hole, the inner sleeve can be fixed at a specific position in the outer sleeve, achieving the adjustment and fixation of the length of the connecting beam 320.

[0079] In another embodiment, the telescopic segment can adopt a threaded adjusting structure, including a sleeve with internal threads fixedly connected with the connecting segment and a rod body with external threads. The outer end of the rod body forms a connecting site for mounting the lifting rod 330. By rotating the rod body, it can move in and out of the sleeve, changing the length of the telescopic segment. When the appropriate length is adjusted, the rod body can be locked on the sleeve by a locking nut to prevent it from rotating by itself. This structure allows more precise length adjustment and is suitable for occasions that require precise positioning.

[0080] In combination with the overall structure of the lithium film lifting mechanism 300, the lifting drive assembly 310 is installed on one side of the column 200 and can be lifted along the column 200, the connecting section of the connecting beam 320 is installed on the lifting drive assembly 310, and the two telescopic sections are respectively arranged at both ends of the connecting section, and the end of each telescopic section away from the connecting section forms a connecting position. Two lifting rods 330 are respectively installed in one connecting position and extend away from the side of the column 200, and the top of each lifting rod 330 is provided with a lifting groove 340 for lifting the lithium film. This structure enables the lithium film lifting mechanism 300 to adjust the distance between the lifting rods 330 according to the width of different lithium films, thereby improving the adaptability and practicality of the device.

[0081] The segmented adjustable connecting beam 320 structure in the embodiment solves the technical problem of poor adaptability of the conventional lithium film carrying device. In the conventional structure, the connecting beam 320 is usually of fixed length, and the distance between the lifting rods 330 cannot be adjusted, so that only lithium films of a specific width can be carried. When lithium films of different widths need to be carried, different specifications of connecting beams 320 or the entire lifting mechanism may need to be replaced, which increases the equipment cost and operation complexity. The segmented adjustable connecting beam 320 including the connecting section and the two telescopic sections can flexibly adjust the distance between the lifting rods 330 according to the width of the lithium film, so that the same set of device can adapt to lithium films of various specifications, greatly improving the versatility and economy of the device.

[0082] In addition, this connecting beam 320 structure also facilitates the transportation and storage of the device. When not in use, the two telescopic sections can be retracted to the shortest state, reducing the overall length of the connecting beam 320 and saving storage space. At the same time, due to the segmented structure, the parts of the connecting beam 320 can be made of different materials or have different structural forms, which can be optimized according to their respective functional requirements. For example, the connecting section can be made of high-strength material to provide sufficient support force, while the telescopic section can be made of lightweight material to reduce the overall weight, thereby reducing energy consumption while ensuring strength.

[0083] In an embodiment, one side of the column 200 is formed with a vertical sliding groove 360, and the lifting drive assembly 310 is installed in the sliding groove 360 and in sliding fit with the sliding groove 360.

[0084] Specifically, the column 200 serves as the vertical support structure of the lithium film handling device, and a chute 360 extending vertically is formed on one side of the column 200. The chute 360 can be directly machined on the column 200 or formed by an additional component. The chute 360 extends along the vertical direction of the column 200, and its length should cover the entire lifting stroke required by the lifting drive assembly 310, ensuring that the lifting drive assembly 310 can freely lift within the required height range. The cross-sectional shape of the chute 360 can be "T" shape, "dove tail" shape, rectangular shape or other suitable shapes for sliding fit, which can both limit the lateral movement of the lifting drive assembly 310 and ensure smooth sliding in the vertical direction.

[0085] The lifting drive assembly 310 is installed in the chute 360 and forms a sliding fit with the chute 360. The shape of the lifting drive assembly 310 matches the inner shape of the chute 360, ensuring that the fit between the two is both tight and smooth. At the sliding fit, low-friction materials such as nylon, polytetrafluoroethylene, etc. can be used as the sliding contact surface, or a lubricant can be applied to the contact surface to reduce friction and improve the stability and energy efficiency of the lifting.

[0086] In actual application, the sliding fit structure of the chute 360 and the lifting drive assembly 310 provides stable guidance and support for the lifting drive assembly 310. When the lifting drive assembly 310 is working, it will move up and down along the chute 360, driving the connecting beam 320 and the lifting rod 330 to lift together, thereby achieving the position adjustment of the lithium film in the vertical direction. The guiding effect of the chute 360 ensures straight-line motion during lifting, preventing the lifting drive assembly 310 from rotating or shifting laterally, and ensuring the stability of the entire lithium film lifting mechanism 300.

[0087] In a specific embodiment, the chute 360 can have a "T" shaped cross-section, and the lifting drive assembly 310 is correspondingly provided with a sliding block matching the "T" shaped chute 360. The sliding block is embedded in the chute 360 and can slide up and down along the chute 360, but is limited within the chute 360 and cannot move laterally out. Ball bearings or pulleys can be installed between the sliding block and the chute 360 to further reduce friction and improve the stability and response speed of the lifting. The main part of the lifting drive assembly 310 is located outside the chute 360, connected to the chute 360 through the sliding block, and the main body can be installed with driving elements such as motors, reducers and transmission mechanisms, as well as connecting components for connecting the connecting beam 320.

[0088] In another embodiment, the sliding groove 360 can adopt a double-track structure, that is, two parallel guide rails are arranged on one side of the stand 200 to form an outwardly open channel. The lifting driving assembly 310 is provided with a slider matching the double-track, and the slider is embedded between the two guide rails and can slide up and down along the guide rails. This double-track structure provides better stability and carrying capacity, and is suitable for situations where heavy lithium film is carried.

[0089] In combination with the overall structure of the lithium film lifting mechanism 300, the stand 200 is installed at a mounting position on the walking mechanism 100 and extends vertically upward. One side of the stand 200 is formed with a sliding groove 360 extending vertically, and the lifting driving assembly 310 is installed in the sliding groove 360 and in sliding cooperation with the sliding groove 360. The connecting beam 320 is installed on the lifting driving assembly 310 and extends horizontally, with both ends thereof located outside the stand 200. The lifting rods 330 are respectively installed on the connecting positions at both ends of the connecting beam 320, extend toward the side away from the stand 200, and have lifting grooves 340 at the top thereof for lifting the lithium film. Through this structure, the lithium film lifting mechanism 300 can stably lift along the stand 200 to realize vertical position adjustment of the lithium film.

[0090] The structure of the sliding groove 360 in cooperation with the lifting driving assembly 310 in the embodiment solves the technical problem of unstable lifting of the conventional lithium film carrying device. In the conventional structure, the lifting driving assembly 310 is usually directly installed on the surface of the stand 200 or connected through a simple clamp, etc. This connection mode is prone to shaking or deviation during lifting, especially when heavy lithium film is carried or rapid lifting is performed, which can cause the lithium film to shake or even fall off, resulting in damage. The structure that the stand 200 is formed with the sliding groove 360 on one side and the lifting driving assembly 310 is installed in the sliding groove 360 and in sliding cooperation with the sliding groove 360 can provide more stable guidance and support, ensure the stability and accuracy of the lifting process, and effectively prevent the lithium film from being damaged due to unstable lifting during carrying.

[0091] In addition, this structure of the sliding groove 360 in cooperation with the sliding groove has the advantages of strong carrying capacity and good resistance to lateral force. When the lithium film is heavy or unevenly distributed, a large torque and lateral force will be generated on the lifting driving assembly 310. The sliding groove 360 structure can effectively disperse and withstand these forces to prevent the lifting driving assembly 310 from tilting or deforming, ensuring the stability and safety of the entire lithium film lifting mechanism 300. At the same time, the sliding groove 360 structure also facilitates the installation and maintenance of the lifting driving assembly 310. When the lifting driving assembly 310 needs to be repaired or replaced, it can be simply slid out of the sliding groove 360, simplifying the maintenance work and reducing the maintenance cost.

[0092] In an embodiment, the lifting driving assembly 310 comprises a sliding runner 370 and a mounting base 380, the sliding runner 370 is in sliding fit with the sliding groove 360 and runs along the sliding groove 360, and the mounting base 380 is mounted on the sliding runner 370, and the connecting beam 320 is mounted on the mounting base 380.

[0093] Specifically, the lifting driving assembly 310 adopts a split structure, comprising two main parts of the sliding runner 370 and the mounting base 380. The sliding runner 370 is a component in direct contact and sliding fit with the sliding groove 360 on the stand 200, and its outer shape matches the inner shape of the sliding groove 360, ensuring that the fit between the two is both tight and smooth. The sliding runner 370 can be made of wear-resistant materials such as nylon, polytetrafluoroethylene or metal alloy materials to reduce friction between the sliding runner 370 and the sliding groove 360 and improve the stability and service life of the lifting. The main function of the sliding runner 370 is to run up and down along the sliding groove 360 to provide the lifting driving assembly 310 with the ability to move vertically.

[0094] The contact surface of the sliding runner 370 in sliding fit with the sliding groove 360 can be designed as line contact or surface contact to reduce friction and increase contact stability. In some embodiments, rollers or ball bearings can be installed on the sliding runner 370 to form rolling contact between the sliding runner 370 and the sliding groove 360 instead of sliding contact, further reducing friction and improving the stability and energy efficiency of the lifting. The shape of the sliding runner 370 can be block-shaped, plate-shaped or other shapes suitable for fitting with the sliding groove 360, and a dustproof sealing device can be provided thereon to prevent dust and impurities from entering the contact surface between the sliding groove 360 and the sliding runner 370, maintaining the smoothness of the sliding.

[0095] The mounting base 380 is an intermediate component connecting the sliding runner 370 and the connecting beam 320, and is mounted on the sliding runner 370. The mounting base 380 can be made of metal materials such as aluminum alloy or steel, which has sufficient strength and rigidity to withstand the load brought by the connecting beam 320 and the lifting rod 330. The mounting base 380 can be provided with reinforcing ribs or thickened areas to enhance its carrying capacity and stability. The mounting base 380 and the sliding runner 370 can be connected by bolts, welding or other fixing methods to form a firm connection.

[0096] The connecting beam 320 is mounted on the mounting base 380, and the two can be connected by bolts, buckles or other detachable connection methods for easy maintenance and replacement. The mounting base 380 can be provided with multiple connection points or connection surfaces to accommodate different types or sizes of connecting beams 320, enhancing the versatility and flexibility of the device.

[0097] In actual application, when the lifting driving assembly 310 works, the sliding walking piece 370 moves up and down along the sliding groove 360 on the stand column 200, driving the mounting base 380 and the connecting beam 320 to lift together. The lifting rods 330 at the two ends of the connecting beam 320 move up and down accordingly, realizing the position adjustment of the lithium film in the vertical direction. The sliding cooperation between the sliding walking piece 370 and the sliding groove 360 ensures the linear motion in the lifting process, preventing the lifting driving assembly 310 from rotating or shifting laterally, and ensuring the lifting stability of the whole lithium film lifting mechanism 300.

[0098] In a specific embodiment, the sliding walking piece 370 can adopt a sliding block with a "T" shaped section, matching with the "T" shaped section sliding groove 360 on the stand column 200. The sliding block is embedded in the sliding groove 360 and can slide up and down along the sliding groove 360, but is limited in the sliding groove 360 and cannot move laterally out of the sliding groove 360. The surface of the sliding block can be coated with a material with low friction coefficient, such as polytetrafluoroethylene, to reduce the friction with the sliding groove 360. The mounting base 380 can adopt an "L" shaped structure, one end of which is connected with the sliding block, and the other end extends outward to form a mounting platform for mounting the connecting beam 320.

[0099] In another embodiment, the sliding walking piece 370 can include a plurality of rollers distributed at different positions of the sliding walking piece 370, which form rolling contact with the inner wall of the sliding groove 360. The rollers can adopt a bearing structure to reduce the rotating friction, improve the stability and response speed of the lifting. The mounting base 380 can adopt a frame structure to connect all the rollers and form a mounting surface on the outside for connecting the connecting beam 320.

[0100] In combination with the overall structure of the lithium film lifting mechanism 300, the stand column 200 is installed on the mounting position on the walking mechanism 100 and extends upward in the vertical direction. One side of the stand column 200 is formed with a sliding groove 360 extending in the vertical direction, and the sliding walking piece 370 of the lifting driving assembly 310 is in sliding cooperation with the sliding groove 360 and walks along the sliding groove 360. The mounting base 380 is installed on the sliding walking piece 370, and the connecting beam 320 is installed on the mounting base 380 and extends in the horizontal direction, so that the two ends thereof are located outside the stand column 200. The lifting rods 330 are installed on the connecting positions at the two ends of the connecting beam 320, respectively, and extend towards the side away from the stand column 200, and the top thereof is formed with a lifting groove 340 for lifting the lithium film. Through this structure, the lithium film lifting mechanism 300 can stably lift along the stand column 200, realizing the position adjustment of the lithium film in the vertical direction.

[0101] The split lifting drive assembly 310 structure in this embodiment solves the technical problem of complex structure and difficult maintenance of the conventional lithium film carrying device lifting drive assembly 310. In the conventional structure, the lifting drive assembly 310 is usually an integral structure, and when a part is damaged or needs to be repaired, the entire assembly often needs to be replaced, increasing maintenance costs and time. By adopting a split structure including a sliding walking piece 370 and a mounting seat 380, a part can be replaced or repaired individually according to actual needs, reducing maintenance costs and improving the efficiency of the device.

[0102] In addition, such a split structure also has the advantages of flexible installation and strong adaptability. The sliding walking piece 370 is focused on sliding cooperation with the sliding groove 360 to ensure the stability and stability of lifting; the mounting seat 380 is responsible for connecting the sliding walking piece 370 and the connecting beam 320, and different forms of mounting seat 380 can be selected according to different types of connecting beam 320 or use requirements, enhancing the versatility and flexibility of the device. At the same time, the split structure also facilitates the optimization of each component, such as selecting low-friction materials for the sliding walking piece 370 and high-strength materials for the mounting seat 380, which reduces costs while ensuring performance.

[0103] It needs to be particularly and explicitly pointed out that the side of the column 200 away from the sliding groove 360 is provided with a handrail 400. The column 200 is provided with a control module 500, which is in communication connection with the lithium film lifting mechanism 300 and controls the lithium film lifting mechanism 300 to lift along the column 200.

[0104] In an embodiment, the walking mechanism 100 includes a base 110 and a plurality of walking wheels 120, and the mounting position is formed on the top of the base 110, and a plurality of walking wheels 120 are distributed on the bottom of the base 110.

[0105] Specifically, the walking mechanism 100 is used as a moving platform of the lithium film carrying device, and adopts a structure combining the base 110 and the walking wheels 120. The base 110 is the main part of the walking mechanism 100, which provides a platform to support the entire lithium film carrying device. The base 110 can be made of metal materials such as aluminum alloy and steel, which has sufficient strength and stiffness to withstand the weight of the column 200, the lithium film lifting mechanism 300 and the lithium film without obvious deformation. The shape of the base 110 can be rectangular, circular or other geometric shapes, which is selected according to actual use requirements and space limitations.

[0106] The top of the base 110 is formed with mounting positions for mounting the column 200. The mounting positions can be recesses, mounting holes or specially designed mounting platforms processed on the top of the base 110, which match the shape and size of the bottom of the column 200 to ensure that the column 200 can be stably mounted on the base 110. The mounting positions are usually located at the center of the base 110 or near one side of the base 110 to maintain the balance of the entire device when moving. Reinforcing ribs or thickened areas can be provided on the mounting positions to enhance their ability to carry the column 200 and prevent deformation or damage due to excessive load during use.

[0107] The connection between the base 110 and the column 200 can be bolted, welded or other fixed way to form a firm connection. In some embodiments, the mounting positions can be designed as adjustable structures to allow the column 200 to adjust the angle or position within a certain range to adapt to different working environments and needs.

[0108] A plurality of walking wheels 120 are distributed at intervals on the bottom of the base 110 to provide the entire device with the ability to move. The walking wheels 120 can be made of wear-resistant materials such as polyurethane, rubber or nylon, etc., which have good wear resistance and grip. The diameter and width of the walking wheels 120 should be selected according to the total weight of the device and the use environment to ensure that the device can walk smoothly and will not damage the ground.

[0109] The number and distribution of the walking wheels 120 should be reasonably set, usually three or four, evenly distributed around the bottom of the base 110 or at specific positions to ensure the stability and balance of the device. Each walking wheel 120 can be connected to the base 110 through a bearing to reduce the rotational friction and improve the stability and energy efficiency of walking. In some embodiments, the walking wheels 120 can be designed as universal wheels, i.e. wheels that can rotate 360 degrees, to enhance the flexibility and maneuverability of the device, making it easier to operate and turn in complex environments.

[0110] In actual application, the operator can move the walking mechanism 100 by pushing or pulling or controlling the device to drive the entire lithium film carrying device to move forward, backward or turn. The walking wheels 120 are in contact with the ground and bear the weight of the entire device, and provide the ability to move by rolling. The base 110 serves as a support platform to carry the column 200, the lithium film lifting mechanism 300 and the lithium film, and forms a stable connection with the column 200 through the mounting positions.

[0111] In one embodiment, the base 110 can be a rectangular metal plate structure, and four walking wheels 120 are installed at the four corners. Two or all of the walking wheels 120 can be designed as universal wheels with brakes, which can be locked when needed to prevent the device from moving accidentally. The installation position can be a circular recess processed at the center of the top of the base 110, and a plurality of screw holes are uniformly distributed around the recess for fixing the stand 200 to the base 110 by bolts.

[0112] In another embodiment, the base 110 can be designed as an "H" structure composed of two parallel long beams and a cross beam connecting them. This structure can reduce the weight of the base 110 while maintaining sufficient strength. The installation position can be provided on the cross beam, and the walking wheels 120 are installed at the ends of the two long beams to form a four-point support. This structure provides better stability, especially when the device carries a heavy load.

[0113] In combination with the overall structure of the lithium film carrying device, the base 110 of the walking mechanism 100 is provided with an installation position, and the stand 200 is installed at the installation position and extends vertically upward. The lithium film lifting mechanism 300 is installed on the stand 200 and can be lifted along the stand 200 to carry the lithium film along the stand 200 when lifting the lithium film. The walking mechanism 100 can drive the lithium film lifting mechanism 300 carrying the lithium film to walk through the rolling of the plurality of walking wheels 120, realizing the horizontal carrying of the lithium film.

[0114] The base 110 and the plurality of walking wheels 120 in the walking mechanism 100 of the embodiment solve the technical problems of poor mobility and poor stability of the conventional lithium film carrying device. In the conventional structure, the lithium film carrying device is usually fixed at a specific position or needs to rely on additional carrying equipment for movement, which not only increases the operation complexity but also limits the use scenarios of the device. The use of the base 110 and the plurality of walking wheels 120 in the walking mechanism 100 enables the lithium film carrying device to have autonomous mobility, and the operator can easily push the device to the desired position, greatly improving the work efficiency and flexibility.

[0115] In addition, the combination structure of the base 110 and the plurality of walking wheels 120 also has the advantages of strong carrying capacity and good stability. The base 110 serves as a support platform and can evenly distribute the weight of the stand 200, the lithium film lifting mechanism 300, and the lithium film, reducing the pressure on individual components. The plurality of walking wheels 120 are spaced apart at the bottom of the base 110 to form a multi-point support, enhancing the stability of the device during movement and preventing tilting or overturning. At the same time, this structure also facilitates maintenance and replacement, and when the walking wheels 120 are worn or damaged, only the specific walking wheels 120 need to be replaced, without the need to replace the entire walking mechanism 100, reducing maintenance costs.
