[0059] The lifting drive assembly 320 can adopt an electric screw rod or a hydraulic cylinder structure. Taking the electric screw rod as an example, the electric screw rod comprises a motor, a screw rod, and a nut matched with the screw rod. The motor is fixed at the bottom of the slide 210, the screw rod is arranged vertically along the slide 210, and the nut is connected with the sliding block of the sliding module 310. When the motor drives the screw rod to rotate, the nut drives the sliding block to move up and down along the slide 210, thereby realizing the lifting of the material carrying mechanism 400.

[0060] The carrying module of the material carrying mechanism 400 can be detachably installed on the connecting plate of the sliding module 310 through a quick connection mechanism. The quick connection mechanism can adopt a buckle type or a bolt type structure to facilitate the operator to quickly replace the carrying module according to different material characteristics.

[0061] In actual use, the operator first selects a suitable carrying module according to the characteristics of the material to be carried, and installs it on the connecting plate of the sliding module 310. Then, the walking mechanism 100 is moved to the specified position, and the height of the sliding module 310 is adjusted by the lifting drive assembly 320, so that the carrying module reaches the appropriate height position. Finally, the carrying module is used to carry or clamp the material, and the carrying operation is completed.

[0062] The lifting mechanism 300 in the embodiment realizes accurate lifting control of the material carrying mechanism 400 through the cooperation of the sliding module 310 and the lifting drive assembly 320.

Not only the stability and accuracy of the carrier are improved, but also the material carrying demand of different heights and positions can be adapted.

[0064] The lifting movement mechanism 300 provided by the embodiment realizes precise lifting control of the material carrying mechanism 400 through cooperation of the sliding module 310 and the lifting driving assembly 320. Not only the stability and accuracy of the carrier are improved, but also the material carrying demand of different heights and positions can be adapted. In combination with the detachable material carrying mechanism 400, the embodiment effectively solves the technical problems of power waste and inconvenience in the prior art, and provides an efficient and flexible carrying solution for the material production and processing industry.

[0065] In an embodiment, the sliding module 310 includes a base 311 and a plurality of walking wheels 312. The base 311 is slidably installed in the slide 210, both ends of the base 311 in the vertical direction are connected with the lifting driving assembly 320, and the base 311 is detachably connected with the material carrying mechanism 400. The plurality of walking wheels 312 are paired and rotatably installed on both sides of the base 311 in the vertical direction, and all the walking wheels 312 are accommodated in the slide 210.

[0066] The lifting driving assembly 320 can drive the base 311 to drive all the walking wheels 312 to walk along the slide 210, so as to drive the base 311 to lift along the slide 210 when the material carrying mechanism 400 carries materials.

[0067] The base 311 can be made of lightweight high-strength materials such as aluminum alloy or carbon fiber composite materials to reduce the overall weight and ensure sufficient strength.

[0068] The walking wheels 312 can be made of high-strength engineering plastics or metal materials, and the rims can be covered with wear-resistant materials such as polyurethane to reduce friction and prolong service life. The walking wheels 312 are rotatably installed on both sides of the base 311 through bearings to ensure the smoothness of the sliding process. The diameter of the walking wheels 312 should be smaller than the inner width of the slide 210, so that all the walking wheels 312 can be completely accommodated in the slide 210 to avoid interference with the external structure of the slide 210.

[0069] The lifting driving assembly 320 can adopt an electric screw rod or a hydraulic cylinder structure.

The motor is fixed at the bottom of the slide 210, the screw rod is vertically arranged along the slide 210, and the nut is connected with the upper and lower ends of the base 311. When the motor drives the screw rod to rotate, the nut drives the base 311 to move up and down along the slide 210, thereby realizing the lifting of the material carrying mechanism 400.

[0070] In actual use, the operator first installs the selected material carrying mechanism 400 on the base 311. Then, by controlling the lifting driving assembly 320, the base 311 is driven to drive all the walking wheels 312 to walk along the slide 210, so that the material carrying mechanism 400 reaches a suitable height position. After the material carrying mechanism 400 carries the material, the lifting driving assembly 320 can continue to drive the base 311 to lift along the slide 210 as needed to complete the material carrying operation.

[0071] The slide module 310 in the embodiment realizes the stable lifting of the material carrying mechanism 400 through the cooperation of the base 311 and the plurality of walking wheels 312. The setting of the walking wheels 312 reduces the friction between the base 311 and the slide 210, improves the fluency and accuracy of the lifting process, and improves the flexibility and applicability of the carrying vehicle. At the same time, the structure design that all the walking wheels 312 are accommodated in the slide 210 ensures the compactness and safety of the entire lifting system.

[0072] The slide module 310 in the embodiment is the core part of the lifting movement mechanism 300, and forms a complete material carrying system with the walking mechanism 100 and the material carrying mechanism 400.

Not only the stability and accuracy of the carrying vehicle are improved, but also the material carrying demand of different heights and positions can be adapted.

[0073] The slide module 310 provided in the embodiment realizes the stable and accurate lifting of the material carrying mechanism 400 through the cooperation of the base 311 and the plurality of walking wheels 312. In combination with the detachable material carrying mechanism 400, the embodiment effectively solves the technical problems of power waste and inconvenience in the prior art, and provides an efficient and flexible carrying solution for the material production and processing industry.

[0074] In an embodiment, a plurality of bolt holes 313 are formed on the base 311 in a spaced distribution manner, and the material carrying mechanism 400 is detachably connected with the base 311 through bolts.

[0075] The bolt holes 313 on the base 311 can be distributed in an array, for example, a plurality of rows and columns of bolt holes 313 can be arranged on the top surface of the base 311. This distribution can adapt to different sizes and types of material carrying mechanisms 400, improving the versatility and adaptability of the trolley. The bolt holes 313 can adopt standard thread specifications, such as M6 or M8 threads, to match commonly used bolts.

[0076] The bottom of the material carrying mechanism 400 can be correspondingly provided with mounting holes matching the positions of the bolt holes 313 of the base 311. During installation, the operator can select appropriate bolt hole 313 positions for connection according to the specific size and weight distribution of the material carrying mechanism 400. The stability and balance of the material carrying mechanism 400 on the base 311 can be ensured.

[0077] The bolts can be made of high-strength alloy materials, such as stainless steel or galvanized steel, to provide sufficient connection strength and corrosion resistance. The length of the bolts should be reasonably selected according to the thickness of the base 311 and the material carrying mechanism 400 to ensure that the bolts can completely pass through the two components and have an appropriate margin.

[0078] In actual use, when different types of material carrying mechanisms 400 need to be replaced, the operator only needs to disassemble the bolts to easily remove the original carrying mechanism and then install a new one.

[0079] In addition, the plurality of spaced bolt holes 313 also provide the possibility of adjusting the position of the material carrying mechanism 400. The operator can fine-tune the front, back, left and right positions of the carrying mechanism according to actual needs by selecting different bolt hole 313 positions to adapt to different sizes and center of gravity distribution of the material.

[0080] The bolt connection method of the embodiment serves as the connection structure between the base 311 and the material carrying mechanism 400, forming a complete detachable material handling system with the entire sliding module 310 and the lifting mechanism 300. Not only does it ensure the stable connection between the material carrying mechanism 400 and the base 311, but it also provides flexibility for quick replacement and position adjustment, further enhancing the adaptability and efficiency of the entire trolley.

[0081] The plurality of spaced bolt holes 313 on the base 311 provided by the embodiment, combined with the bolt connection method, achieve reliable and flexible detachable connection between the material carrying mechanism 400 and the base 311. It not only simplifies the installation and replacement process of the carrying mechanism, but also provides the possibility of position adjustment, effectively improving the versatility and work efficiency of the trolley.

[0082] In an embodiment, the lifting driving assembly 320 comprises a driving member 321, two sprockets 322 and a connecting chain 323. The driving member 321 is installed on the walking mechanism 100, and the output end of the driving member 321 is rotatably extended through the guide column 200 and into the slide 210. The two sprockets 322 are spaced apart on the top and bottom of the slide 210, and the sprocket 322 at the bottom is connected with the output shaft of the driving member 321. The connecting chain 323 is engaged with the two sprockets 322, and the two ends of the connecting chain 323 are connected with the top and bottom of the base 311 respectively. The driving member 321 can drive the sprocket 322 at the bottom to rotate, so as to drive the sprocket 322 at the top to rotate through the connecting chain 323, and drive the base 311 to ascend and descend along the slide 210.

[0083] The driving member 321 can adopt a power source such as a motor or a hydraulic motor, which is installed on the walking mechanism 100 to ensure the stability of the entire lifting system. The output end of the driving member 321 is extended through the guide column 200 and into the slide 210, which not only ensures the transmission of driving force, but also avoids occupying the space in the slide 210 by the driving member 321.

[0084] The two sprockets 322 are respectively located on the top and bottom of the slide 210, forming a vertical transmission system. The sprocket 322 at the bottom is directly connected with the output shaft of the driving member 321, which can be achieved by synchronous rotation through key connection or spline connection. The sprocket 322 at the top can be supported by a bearing on the top of the slide 210 to ensure its free rotation.

[0085] The connecting chain 323 is engaged with the two sprockets 322, forming a closed-loop transmission system. The material of the chain can be high-strength alloy steel to withstand frequent lifting and loading. The two ends of the chain are connected with the top and bottom of the base 311 respectively, which can be achieved by pin shaft connection or bolt connection to ensure the reliability and detachability of the connection.

[0086] In actual use, when the material carrying mechanism 400 needs to be lifted, the driving member 321 is started and drives the sprocket 322 at the bottom to rotate. Through the transmission of the chain, the sprocket 322 at the top rotates synchronously, thereby driving the base 311 to move up and down along the slide 210.

[0087] In addition, this chain transmission lifting method has self-locking performance, that is, when the driving member 321 stops working, the base 311 can remain at the current position without sliding down. The driving member 321 is installed on the walking mechanism 100, and through the cooperation of the guide column 200 and the slide 210, precise lifting control of the base 311 is achieved.

[0088] The lifting driving assembly 320 provided by the embodiment realizes the stable and accurate lifting of the base 311 through the ingenious cooperation of the driving member 321, the chain wheel 322 and the connecting chain 323. Not only is the transmission efficiency high, but also the self-locking performance is provided, thereby improving the safety and stability of the carrying process. In combination with the detachable material bearing mechanism 400, the embodiment effectively solves the technical problems of power waste and inconvenient carrying in the prior art, and provides an efficient and reliable carrying solution for the material production and processing industry.

[0089] In an embodiment, the top and bottom of the slide 210 are formed with limiting protrusions 324, and the top of the base 311 is provided with a limiting member 325 capable of being accommodated in the slide 210, and the limiting member 325 is capable of abutting against the limiting protrusion 324 at the top.

[0090] The limiting protrusions 324 at the top and bottom of the slide 210 can be integrally formed with the slide 210, or can be of a detachable structure, thereby facilitating installation and maintenance. The limiting protrusions 324 can be made of high-strength alloy, such as aluminum alloy or titanium alloy, to provide sufficient strength and wear resistance. The limiting protrusions 324 can be designed in a circular arc shape or a bevel shape to reduce the impact force when contacting the limiting member 325.

[0091] The limiting member 325 at the top of the base 311 can be of a roller or sliding block structure, and can be made of engineering plastic or metal material with good wear resistance. The size of the limiting member 325 is slightly smaller than the inner cavity size of the slide 210, so that the limiting member 325 can freely move in the slide 210 and effectively abut against the limiting protrusion 324. The limiting member 325 can be detachably connected to the base 311 by means of bolts or pins, thereby facilitating replacement and maintenance.

[0092] In actual use, when the base 311 rises to the top of the slide 210, the limiting member 325 abuts against the limiting protrusion 324 at the top, thereby preventing the base 311 from continuing to rise and separating from the slide 210. This limiting mechanism effectively prevents the overshoot phenomenon that may occur during lifting, thereby improving the safety of the entire system. At the same time, the limiting protrusion 324 at the bottom also prevents the base 311 from descending excessively, thereby ensuring that the base 311 always remains within a safe working range.

[0093] In addition, the abutment of the limiting member 325 and the limiting protrusion 324 also plays a buffering role. When the base 311 rapidly rises to the top, the contact between the limiting member 325 and the limiting protrusion 324 can absorb part of the impact force, thereby reducing the impact on the entire system and prolonging the service life of the equipment.

[0094] When the driving member 321 rises through the chain wheel 322 and the chain, the limiting member 325 can effectively prevent the base 311 from exceeding the safe range, providing reliable protection for the entire material handling process.

[0095] The configuration of the slide 210 limiting protrusion 324 and the base 311 limiting member 325 provided by the embodiment realizes effective limiting and protection of the lifting process of the base 311. Not only improves the safety and stability of the material handling vehicle, but also reduces the impact and wear of moving parts, prolongs the service life of the equipment. Through this simple and effective limiting mechanism, the embodiment further improves the overall performance of the material handling vehicle, providing more reliable protection for the safe and efficient handling of materials.

[0096] In an embodiment, the walking mechanism 100 includes a base 110 and a walking assembly 120. The guide column 200 is installed on the top of the base 110, and the walking assembly 120 is installed on the bottom of the base 110. The walking assembly 120 can move the material carrying mechanism 400 through the guide column 200 installed on the base 110.

[0097] The base 110, as the basic component of the walking mechanism 100, can be made of high-strength lightweight materials such as aluminum alloy or engineering plastics to ensure the stability and lightweight of the overall structure. The shape of the base 110 can be designed according to actual needs, for example, a rectangular or circular platform structure can be used, and mounting holes or grooves can be provided at the bottom for fixing the walking assembly 120.

[0098] The guide column 200 is installed on the top of the base 110 and can be fixed by bolt connection or welding. The material of the guide column 200 should have sufficient strength and rigidity, such as stainless steel or high-strength alloy, to withstand the weight of the material carrying mechanism 400 and the stress during movement. The height of the guide column 200 should be determined according to the actual needs of material handling to ensure that the material carrying mechanism 400 has enough lifting space.

[0099] The walking assembly 120 is installed on the bottom of the base 110 and can include an electric wheel or a track type structure. Taking the electric wheel as an example, one universal wheel 122 can be installed at each corner of the bottom of the base 110, of which at least two are power wheels equipped with motor drive. The motor can use a stepper motor or a servo motor to achieve precise control. The installation method of the walking assembly 120 should be convenient for maintenance and replacement, and a quick release type structure can be used.

[0100] In actual use, when the material carrying mechanism 400 needs to be moved, the control system starts the walking assembly 120. The electric wheels start to rotate, driving the entire base 110 to move. Since the guide column 200 is fixed on the base 110, it will move with the base 110, thereby synchronously moving the material carrying mechanism 400 connected thereto. The horizontal movement of the material carrying mechanism 400 is achieved, enabling it to be flexibly transferred between different stations.

[0101] In addition, the walking assembly 120 can be equipped with position sensors and encoders to achieve precise positioning and path planning. It can be ensured that the material handling vehicle can move according to the preset route, avoiding collision and improving work efficiency.

[0102] The walking mechanism 100 provided by the embodiment realizes stable movement and precise positioning of the material handling vehicle through the clever cooperation of the base 110, the guide and the walking assembly 120. Not only does it improve the flexibility and efficiency of the carrying process, but also provides a reliable basis for the lifting movement of the material carrying mechanism 400. Through this integrated walking mechanism 100, the embodiment effectively solves the movement and positioning problems in the material handling process, providing an efficient and accurate carrying solution for the lithium film and other material production and processing industries.

[0103] In an embodiment, the base 110 has walking ends and pushing ends formed at both ends; the walking assembly 120 includes two directional wheels 121 and two universal wheels 122, the two directional wheels 121 are oppositely and spacedly distributed at the walking ends of the base 110, and the two universal wheels 122 are oppositely and spacedly distributed at the pushing ends of the base 110.

[0104] The formation of the walking ends and the pushing ends of the base 110 ensures the reasonable arrangement of the walking assembly 120. The two directional wheels 121 oppositely and spacedly distributed at the walking ends provide stability and directionality when walking in a straight line. The directional wheels 121 can be made of polyurethane material, which has good wear resistance and shock absorption performance. The diameter and width of the directional wheels 121 should be selected according to the overall weight of the material handling vehicle and the expected load, to ensure sufficient carrying capacity and ground contact area.

[0105] The two universal wheels 122 oppositely and spacedly distributed at the pushing ends give the material handling vehicle the ability to flexibly turn. The universal wheels 122 can be selected from heavy-duty industrial universal wheels 122, equipped with high-quality bearings to ensure smooth rotation in all directions. The installation height of the universal wheels 122 should be consistent with that of the directional wheels 121 to ensure the balance of the entire base 110.

[0106] In actual use, when the material handling vehicle needs to move straight, the operator can apply force from the pushing end to achieve stable straight walking by the directionality of the directional wheel 121. When turning or fine adjustment is needed, the omnidirectional rotation characteristics of the universal wheel 122 can be used to easily achieve various complex movement trajectories.

[0107] This wheel arrangement is also beneficial to the center of gravity distribution of the material handling vehicle. Since the material is usually heavy, arranging the directional wheel 121 at the walking end can better bear the main load, while the universal wheel 122 at the pushing end is mainly used for direction control and auxiliary support. This design effectively prevents the risk of tipping during material handling, improving overall stability and safety.

[0108] In addition, this arrangement also facilitates the maintenance and replacement of the material handling vehicle. The operator can replace the worn directional wheel 121 or universal wheel 122 according to actual use, without the need to replace the entire walking assembly 120, thereby reducing maintenance costs and time. The formation of the walking end and the pushing end at both ends of the base 110, as well as the specific arrangement of the directional wheel 121 and the universal wheel 122, achieve stable walking and flexible turning of the material handling vehicle.

[0109] In an embodiment, the base 110 includes a connecting beam 111 and two main beams 112, the main beam 112 includes a walking section 113 and a sunken section 114 connected in sequence, the pushing end is formed at one end of the sunken section 114 away from the walking section 113, the walking end is formed at one end of the walking section 113 away from the sunken section 114, and the two main beams 112 are arranged at both ends of the connecting beam 111, and the guide column 200 is installed on the top of the connecting beam 111.

[0110] The connecting beam 111, as the central support structure of the base 110, can be made of high-strength materials such as carbon steel or aluminum alloy to ensure the rigidity and stability of the overall structure. The length of the connecting beam 111 should be determined according to the overall size requirements of the material handling vehicle, and its cross section can be designed as an I-shaped or rectangular tubular shape to provide sufficient strength and lightweight characteristics.

[0111] The two main beams 112 are arranged at both ends of the connecting beam 111 to form an "H" shaped structure, increasing the lateral stability of the base 110. The design of the walking section 113 and the sunken section 114 of the main beam 112 creates a staggered structure, providing reasonable space for the installation of different functional components. The walking section 113 can be of solid structure to bear the main load during walking; the sunken section 114 can be of hollow structure to reduce weight while ensuring strength.

[0112] The pushing end is formed at one end of the sinking section 114 away from the walking section 113, effectively reducing the height of the pushing end, which is conducive to the comfort of the operator's posture when exerting force, and also lowers the center of gravity of the material handling vehicle, improving overall stability. The walking end is formed at one end of the walking section 113 away from the sinking section 114, maintaining a higher position, which is conducive to the installation of the directional wheel 121, ensuring the stability of walking.

[0113] The guide column 200 is installed on the top of the connecting beam 111, so that the guide column 200 is in the center position of the base 110, which can evenly disperse the load from the material carrying mechanism 400. The installation of the guide column 200 can adopt flange fixing or welding method to ensure the firm connection with the connecting beam 111.

[0114] In actual use, the base 110 can effectively support and coordinate various functional components of the material handling vehicle. The height difference between the walking end and the pushing end makes it easier for the operator to push and control the vehicle. At the same time, the guide column 200 is in the center position, providing stable lifting guidance for the material carrying mechanism 400, improving the accuracy and safety of the handling process.

[0115] The base 110 structure provided by the embodiment realizes functional partitioning and structural optimization of the material handling vehicle through the ingenious configuration of the connecting beam 111, the main beam 112 and the guide column 200. Not only does it improve the stability and operation convenience of the vehicle, but also provides a reasonable space layout for the installation and coordination of various functional components. Through this innovative base 110 structure, the embodiment further improves the overall performance of the material handling vehicle, providing a solid foundation for efficient and safe material handling.

[0116] In an embodiment, the material carrying mechanism 400 is any one of a carrying plate, a carrying rod, a carrying tray or a carrying clamp jaw.

[0117] The carrying plate can be made of lightweight high-strength materials such as carbon fiber composite materials or aluminum alloys. The surface of the carrying plate can be treated to prevent static electricity from causing damage to the material during handling. The size of the carrying plate can be designed according to the specifications of common materials, and the edges can be provided with anti-slip protrusions to ensure that the materials do not slip during handling.

[0118] The carrying rod can be made of metal materials such as stainless steel or aluminum alloy. The carrying rod can be designed to have adjustable length to adapt to materials of different widths. The surface of the carrying rod can be covered with soft materials such as silicone to increase friction and protect the material.

[0119] The bearing tray can be made of engineering plastic or metal material, and the bottom of the tray can be designed as a grid or honeycomb structure or a structure with a hollow center, which not only reduces the weight but also ensures the strength. The edge of the tray can be provided with a foldable baffle or a carrying arc-shaped tray groove, which can be folded to save space when not in use. The bearing tray is suitable for carrying multiple small-sized materials or material-related accessories.

[0120] The bearing clamp jaw can be composed of a metal frame and a soft clamping component. The metal frame provides overall strength and can be made of aluminum alloy. The clamping component can use elastic materials such as polyurethane to ensure soft clamping of the material. The clamp jaw can be designed to have an adjustable opening and closing range to adapt to materials of different thicknesses. Pressure sensors can be installed on the inner side of the clamp jaw to control the clamping force and avoid damaging the material.

[0121] In actual application, the operator can select a suitable bearing mechanism according to the characteristics of the material to be carried. For example, for large-area flat materials, a bearing plate can be selected; for roll-shaped materials, a bearing rod can be selected; for multiple small materials or material-related parts, a bearing tray can be selected; for materials that need to be precisely positioned or vertically carried, a bearing clamp jaw can be selected.

[0122] The plurality of material bearing mechanisms 400 provided by the embodiment greatly enhance the adaptability and functionality of the material carrying vehicle. Through the four different types of bearing mechanisms of the bearing plate, the bearing rod, the bearing tray and the bearing clamp jaw, the carrying vehicle can cope with materials of various shapes, sizes and characteristics, effectively solving the diversified needs of material carrying in different production links. The flexible bearing mode not only improves the carrying efficiency, but also maximizes the protection of the material, providing strong support for the fine management in the lithium battery production process.
