Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0034] First, this application provides a lifting and rotating device; please refer to [link to relevant documentation]. Figures 1 to 3 The lifting and rotating device 1 includes a base 10, which serves as the overall support structure for the lifting and rotating device 1 and is used to ensure the stability of the lifting and rotating device 1 during operation.

[0035] The lifting and rotating device 1 includes a first lifting assembly 21, a second lifting assembly 22, and a rotating mechanism 30. The first lifting assembly 21 includes a first driving member 211 and a first lifting member 212. The first driving member 211 is connected to the base 10, and the first driving member 211 is connected to the first lifting member 212 to drive the first lifting member 212 to lift relative to the base 10. The second lifting assembly 22 includes a second driving member 221 and a second lifting member 222. The second driving member 221 is connected to the first lifting member 212, and the second driving member 222 is connected to the second lifting member 222 to drive the second lifting member 222 to lift relative to the first lifting member 212, thereby driving the rotating mechanism 30 and the object to lift. The rotating mechanism 30 is used to carry the object (such as a battery tray) and rotate the object.

[0036] The first drive component 211 serves as the power source for the first lifting assembly 21. Through a tight connection with the base 10, the first drive component 211 is securely mounted on the base 10, providing stable support for subsequent lifting operations. In practical applications, the first drive component 211 can take various forms, such as a cylinder, motor, or hydraulic motor. The specific choice depends on factors such as the design requirements, load capacity, and working environment of the lifting and rotating device 1. The first drive component 211 and the base 10 can be connected by bolts to facilitate the installation, disassembly, and maintenance of the first drive component 211.

[0037] The first lifting component 212, as the motion actuator of the first lifting assembly 21, can be raised and lowered under the drive of the first driving component 211. Simultaneously, the first lifting component 212 also serves as a power source for the second lifting assembly 22, enabling the second lifting assembly 22 to rise and fall synchronously with the first lifting component 212 relative to the base 10. Therefore, when designing the first lifting component 212, factors such as its load capacity, motion accuracy, and connection method with the second lifting assembly 22 need to be comprehensively considered.

[0038] The second drive component 221 serves as another power source for the second lifting assembly 22. Through a tight connection with the first lifting component 212, the second drive component 221 is securely mounted on the first lifting component 212, providing stable support for subsequent lifting actions. In practical applications, the second drive component 221 can take various forms, such as a cylinder, motor, or hydraulic motor. Its specific selection depends on factors such as the design requirements, load capacity, and working environment of the lifting and rotating device 1. The second drive component 221 and the first lifting component 212 can be connected by bolts to facilitate the installation, disassembly, and maintenance of the second drive component 221.

[0039] The second lifting member 222, as the motion execution component of the second lifting assembly 22, can lift and lower relative to the first lifting member 212 under the drive of the second driving member 221. That is, while the second lifting member 222 lifts and lowers relative to the base 10 synchronously with the first lifting member 212, the second lifting member 222 can also lift and lower relative to the first lifting member 212. This makes the lifting and lowering time of the lifting and rotating device 1 significantly shorter within the same lifting stroke, thereby enabling the lifting and rotating device 1 to complete the lifting and rotating operations in a shorter time and effectively improving the working efficiency of the lifting and rotating device 1.

[0040] Specifically, assuming the lifting and rotating device 1 needs to raise an object to a certain height H, relying solely on a single lifting component to complete the entire stroke H would be time-consuming. However, in the lifting and rotating device 1 of this application, when the object needs to be raised to a height H, the first driving component 211 drives the first lifting component 212 to rise a certain height h1. Simultaneously, the second driving component 221 drives the second lifting component 222 to rise a certain height h2 relative to the first lifting component 212, and h1 + h2 = H. Since the two lifting components move simultaneously, it is equivalent to completing more lifting strokes in the same amount of time. Therefore, within the same lifting stroke, the lifting and rotating device 1 can significantly shorten the lifting time. This not only effectively reduces waiting time during battery handling, improving the continuity and efficiency of the entire battery production process, but also reduces equipment energy consumption and extends equipment lifespan.

[0041] In some embodiments, please refer to Figure 1 and Figure 4 The first lifting assembly 21 also includes a first transition member 213, which is connected to the first driving member 211 and the first lifting member 212. The first driving member 211 drives the first transition member 213 to rise and fall relative to the base 10, thereby driving the first lifting member 212 to rise and fall. That is, the first lifting member 212 is connected to the first driving member 211 via the first transition member 213. The stability of the first lifting member 212, as the load-bearing structure of the second lifting assembly 22, directly affects the stability of the second lifting assembly 22. By setting the first transition member 213 between the first lifting member 212 and the first driving member 211, the design of the first lifting member 212 can primarily consider its load-bearing capacity on the second lifting assembly 22 and its connection method with the second lifting assembly 22. The specific structure of the first transition member 213 can be adjusted according to the design of the first lifting member 212 to ensure the power transmission between the first driving member 211 and the first lifting member 212.

[0042] In other words, by setting the first transition piece 213, on the one hand, the power output by the first drive piece 211 can be adjusted and distributed according to actual needs, making the movement of the first lifting piece 212 more precise and controllable; on the other hand, the first transition piece 213 can play a buffering and transitioning role, reducing the impact and vibration that may be generated when the first drive piece 211 directly drives the first lifting piece 212, thereby improving the stability and reliability of the entire lifting process.

[0043] It should be noted that the first transition component 213 can be connected to the first drive component 211 and the first lifting component 212 by bolts, so as to facilitate the installation, disassembly and maintenance of the first transition component 213, the first drive component 211 and the first lifting component 212.

[0044] In some embodiments, the lifting and rotating device 1 further includes a first guide assembly 23, which includes a first guide member 231 and a first movable member 232. The first guide member 231 is connected to the base 10, and a first guide rail is formed within the first guide member 231. The first movable member 232 is movably connected to the first guide member 231 and is also connected to the first lifting member 212. A first driving member 211 drives the first lifting member 212 to rise or fall relative to the base 10 and simultaneously drives the first movable member 232 to rise or fall along the first guide rail. That is, when the first driving member 211 drives the first lifting member 212 to rise or fall relative to the base 10, it simultaneously drives the first movable member 232 to rise or fall along the first guide rail relative to the first guide member 231. This allows the first lifting member 212 to be guided during its rise or fall by utilizing the cooperation between the first movable member 232 and the first guide member 231, ensuring the stability of the first lifting member 212 during the lifting process.

[0045] The first guide member 231 can be a linear bearing, and the first movable member 232 can be a guide shaft. The first guide member 231 can be sleeved on the outer circumferential surface of the first movable member 232, so that the first movable member 232 can slide relative to the first guide member 231 along the first guide rail, thereby improving the stability of the first lifting member 212 during the lifting process.

[0046] It should be noted that the first guide member 231 and the base 10, as well as the first movable member 232 and the first lifting member 212, can be connected by bolts to facilitate the installation, disassembly and maintenance of the first guide member 231 and the base 10, as well as the first movable member 232 and the first lifting member 212.

[0047] In some embodiments, the lifting and rotating device 1 includes a plurality of first guide components 23, which are distributed circumferentially along the first lifting member 212. That is, a plurality of first guide components 231 are fixedly connected to the base 10 circumferentially along the first lifting member 212, and a plurality of first movable components 232 are fixedly connected to the first lifting member 212 circumferentially, so that the first lifting member 212 can be guided in the entire circumferential direction during the lifting or lowering process by the cooperation of the first movable components 232 and the first guide components 231, so as to further improve the stability of the first lifting member 212 during the lifting process.

[0048] At least two first guide components 23 are arranged along a first direction X, and at least two first guide components 23 are arranged along a second direction Y, with the first direction X and the second direction Y forming an angle. Specifically, the lifting and rotating device 1 may include four first guide components 23, which are respectively arranged at the four corners of the first lifting member 212 to ensure the stability of the first lifting member 212 during the lifting process.

[0049] In some embodiments, the second lifting assembly 22 further includes a second transition member 223, which is connected to the second driving member 221 and the second lifting member 222. The second driving member 221 drives the second transition member 223 to lift relative to the first lifting member 212, thereby driving the second lifting member 222 to lift. That is, the second lifting member 222 is connected to the second driving member 221 via the second transition member 223. As the load-bearing structure of the rotating mechanism 30, the stability of the second lifting member 222 directly affects the stability of the object to be transported. By providing the second transition member 223 between the second lifting member 222 and the second driving member 221, the design of the second lifting member 222 can primarily consider its load-bearing capacity for the object to be transported, while the specific structure of the second transition member 223 can be adjusted according to the design of the second lifting member 222 to ensure power transmission between the second driving member 221 and the second lifting member 222.

[0050] In other words, by setting the second transition piece 223, on the one hand, the power output by the second drive piece 221 can be adjusted and distributed according to actual needs, making the movement of the second lifting piece 222 more precise and controllable; on the other hand, the second transition piece 223 can play a buffering and transitioning role, reducing the impact and vibration that may be generated when the second drive piece 221 directly drives the second lifting piece 222, thereby improving the stability and reliability of the entire lifting process.

[0051] It should be noted that the second transition member 223, the second drive member 221, and the second lifting member 222 can be connected by bolts to facilitate the installation, disassembly, and maintenance of the second transition member 223, the second drive member 221, and the second lifting member 222.

[0052] In some embodiments, the lifting and rotating device 1 further includes a second guide assembly 24, which includes a second guide member 241 and a second movable member 242. The second guide member 241 is connected to the first lifting member 212, and a second guide rail is formed within the second guide member 241. The second movable member 242 is movably connected to the second guide member 241 and is also connected to the second lifting member 222. A second driving member 221 is used to drive the second lifting member 222 to rise or fall relative to the first lifting member 212, and to drive the second movable member 242 to rise or fall along the second guide rail. That is, when the second driving member 221 drives the second lifting member 222 to rise or fall relative to the first lifting member 212, it simultaneously drives the second movable member 242 to rise or fall along the second guide rail relative to the second guide member 241. This allows the second lifting member 222 to be guided during its rise or fall by utilizing the cooperation between the second movable member 242 and the second guide member 241, ensuring the stability of the second lifting member 222 during the lifting process.

[0053] The second guide member 241 can be a linear bearing, and the second movable member 242 can be a guide shaft. The second guide member 241 can be sleeved on the outer circumferential surface of the second movable member 242, so that the second movable member 242 can slide relative to the second guide member 241 along the second guide rail, thereby improving the stability of the second lifting member 222 during the lifting process.

[0054] It should be noted that the second guide member 241 and the first lifting member 212, as well as the second movable member 242 and the second lifting member 222, can be connected by bolts to facilitate the installation, disassembly and maintenance of the second guide member 241 and the first lifting member 212, as well as the second movable member 242 and the second lifting member 222.

[0055] In some embodiments, the lifting and rotating device 1 includes a plurality of second guide components 24, which are distributed circumferentially along the second lifting member 222. That is, a plurality of second guide components 241 are fixedly connected to the first lifting member 212 along the circumferential direction of the second lifting member 222, and a plurality of second movable components 242 are fixedly connected to the second lifting member 222 along the circumferential direction of the second lifting member 222. This allows the second lifting member 222 to be guided in the entire circumferential direction during the lifting or lowering process by utilizing the cooperation between the second movable components 242 and the second guide components 241, thereby further improving the stability of the second lifting member 222 during the lifting process.

[0056] At least two second guide components 24 are arranged along the first direction X and at least two second guide components 24 are arranged along the second direction Y, with the first direction X and the second direction Y forming an angle. Specifically, the lifting and rotating device 1 may include four second guide components 24, which are respectively arranged at the four corners of the second lifting member 222 to ensure the stability of the second lifting member 222 during the lifting process.

[0057] In some embodiments, the first lifting assembly 21 includes at least two first driving members 211. The at least two first driving members 211 are disposed at opposite ends of the base 10 along the first direction X, that is, at least two first driving members 211 are disposed at opposite ends of the base 10 along the length direction of the base 10 and are fixedly connected to the base 10. The two first driving members 211 simultaneously drive the first lifting member 212 to lift relative to the base 10 to ensure the lifting stability of the first lifting member 212.

[0058] In some embodiments, the second lifting assembly 22 includes at least two second driving members 221. The at least two second driving members 221 are disposed at opposite ends of the first lifting member 212 along the first direction X, that is, at least two second driving members 221 are disposed at opposite ends of the first lifting member 212 along the length direction of the first lifting member 212 and are fixedly connected to the first lifting member 212. The two second driving members 221 simultaneously drive the second lifting member 222 to lift relative to the first lifting member 212 to ensure the lifting stability of the second lifting member 222.

[0059] In some embodiments, please refer to Figure 3 and Figure 5 The rotating mechanism 30 includes a third driving member 31, a first gear 32, a second gear 33 and a bearing assembly 34 connected in sequence. The third driving member 31 is connected to the second lifting member 222, the second gear 33 meshes with the first gear 32, and the bearing assembly 34 is used to carry objects. The third driving member 31 is used to drive the first gear 32 to rotate, so as to drive the second gear 33 to rotate, and drive the bearing assembly 34 to rotate.

[0060] The third drive component 31 can be a rotary motor for outputting power. The first gear 32 and the second gear 33 transmit power through gear meshing to the bearing component 34, thereby enabling the rotation of the object to be transported. Compared to rack and pinion transmission, the meshing transmission of the two gears reduces the risk of vibration during rotation, thus improving the rotational stability of the lifting and rotating device 1.

[0061] It should be noted that the first gear 32 and the second gear 33 in the embodiments of this application can be in the form of a combination of large and small gears. For example, the first gear 32 is a small gear and the second gear 33 is a large gear. By designing the transmission ratio of the large and small gears, the stable rotation of the lifting and rotating device 1 can be achieved.

[0062] In some embodiments, the support assembly 34 includes a rolling bearing 341 and a support member 342 connected to each other. The rolling bearing 341 is connected to the second gear 33, and the support member 342 is used to support an object. That is, the rolling bearing 341 is connected between the second gear 33 and the support member 342. By providing the rolling bearing 341 between the second gear 33 and the support member 342, the overall load-bearing capacity and load-bearing stability of the support assembly 34 can be improved, thereby ensuring the stability of the rotating mechanism 30 during rotation.

[0063] Specifically, the lifting and rotating device 1 in this embodiment of the application mainly includes the following steps when transporting objects:

[0064] A tray carrying an object (such as a battery) is placed on the support assembly 34. According to the set lifting distance and lifting speed, the first drive component 211 drives the first lifting component 212, the second lifting assembly 22, and the rotating mechanism 30 to rise or fall synchronously relative to the base 10. At the same time, the second drive component 221 in the second lifting assembly 22 drives the second lifting component 222 and the rotating mechanism 30 to rise or fall synchronously relative to the first lifting component 212. Meanwhile, the third drive component 31 in the rotating mechanism 30 drives the first gear 32 to rotate according to the set rotation angle and rotation speed. The first gear 32 drives the second gear 33 to rotate, which in turn drives the support assembly 34 to rotate. When the tray carrying the object rises or falls to the target height, it also rotates to the target angle at the same time. This achieves synchronous lifting and rotation of the lifting and rotating device 1, thereby improving the working efficiency of the lifting and rotating device 1, improving the continuity and efficiency of the entire battery production process, reducing the energy consumption of the equipment, and extending the service life of the equipment.

[0065] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
