[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] In the battery manufacturing process, a stacker is required to transport battery fixtures for testing. However, for multiple circular shelves, the traditional stacker has a complex structure and limited rotation range, and cannot complete the transmission of battery fixtures on multiple circular shelves. Utility Model Content

[0004] The present application provides a rotary lifting device and battery manufacturing equipment, which have a simple structure and can realize the picking and placing operations of battery fixtures on multiple shelves distributed in a ring.

[0005] This application is achieved through the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a rotary lifting device, which includes a base, a column, a rotating unit, a cargo platform and a lifting unit, wherein the column is extended along the vertical direction and is arranged on the base; the rotating unit includes a first driving member and a slewing bearing, the first driving member is arranged on the base, the slewing bearing is connected to the first driving member and the column, and the first driving member is used to drive the column to rotate around its axis; the cargo platform is used to carry a battery clamp; the lifting unit is arranged on the column, the lifting unit is connected to the cargo platform, and the lifting unit is used to drive the cargo platform to rise and fall in the vertical direction.

[0007] In this solution, a plurality of shelves are spaced apart in the peripheral direction of the rotary lifting device, and a plurality of positions are spaced apart in the vertical direction on each shelf, and the positions are used to place battery clamps. The rotary lifting device is suitable for picking up and placing battery clamps on a plurality of shelves distributed in a ring. A lifting unit is provided on the column, and the lifting unit can drive the cargo platform to perform lifting and lowering movements in the vertical direction, so as to realize the picking up and placing of battery clamps in different positions in the height direction of the shelf. A rotating unit is provided on the base, and the rotating unit can drive the column to perform circular motion around its axis, thereby driving the cargo platform to perform rotational motion in the circumferential direction, so as to realize full coverage of a plurality of shelves distributed in a ring. The slewing bearing can provide support for the column. Under the action of the first driving member, the first driving member drives the column to rotate through the slewing bearing, so as to make the column more stable during rotation, thereby improving the stability of the cargo platform during rotation. That is, with the joint cooperation of the rotating unit and the lifting unit, the cargo platform can be driven to realize rotation and lifting movements. The cargo platform can cooperate with different positions in the vertical direction of multiple shelves distributed in the outer peripheral direction of the column to realize the picking and placing operations of the battery clamp, and the structure is simple and easy to implement.

[0008] According to some embodiments of the present application, the lifting unit includes two pulleys, a transmission member and a second driving member. The two pulleys are spaced apart on the column in the vertical direction, and the pulleys are rotatably installed on the column; the transmission member is sleeved on the two pulleys, the transmission member is connected to the pulleys, and the cargo platform is connected to the transmission member; the second driving member is arranged on the column, and the second driving member is used to drive any one of the two pulleys to rotate, so as to drive the transmission member to move in the vertical direction.

[0009] In the above scheme, the lifting unit is adopted as a pulley mechanism, and the second driving member is installed on the column. The second driving member drives one of the two pulleys to rotate, and the transmission member is driven to move under the rotation of the pulley. The cargo platform is connected to the transmission member, and the transmission member drives the cargo platform to perform lifting and lowering movements. Under the transmission action of the transmission member, a relatively stable lifting power is provided to the cargo platform.

[0010] According to some embodiments of the present application, the transmission member includes a synchronous belt, which is meshed with a pulley.

[0011] In the above scheme, by using a synchronous belt as the transmission part, compared with using a wire rope or a transmission chain as the transmission part, the synchronous belt is non-metallic, and the friction between the synchronous belt and the pulley will not produce metal powder, thereby reducing the probability of metal powder introduction and meeting the transportation environment requirements of the battery clamp.

[0012] According to some embodiments of the present application, a counterweight is provided on the synchronous belt, and the counterweight and the cargo platform are respectively provided on opposite sides of the synchronous belt.

[0013] In the above scheme, by arranging a counterweight block on the synchronous belt, when the synchronous belt drives the cargo platform to rise, the counterweight block can provide downward gravity to the other side of the synchronous belt, thereby reducing the load on the second drive component in the process of driving the cargo platform to rise, reducing the working power of the second drive component, and also playing a certain protective role for the second drive component.

[0014] According to some embodiments of the present application, the lifting unit also includes a first guide rail, which extends in a vertical direction and is arranged on the column. The cargo platform slides with the first guide rail, and the first guide rail is used to guide the cargo platform to move in the vertical direction.

[0015] In the above scheme, through the setting of the first guide rail, the first guide rail and the cargo platform are slidably matched. In the process of the transmission member driving the cargo platform to rise and fall, the first guide rail can provide a guiding function for the cargo platform, making the cargo platform more stable during the lifting process.

[0016] According to some embodiments of the present application, the second driving member is disposed at one end of the column close to the base.

[0017] In the above solution, by arranging the second driving member on one end of the column close to the base, the installation height of the second driving member is lowered, the maintenance difficulty of the second driving member is reduced, and the maintenance and replacement of the second driving member is facilitated.

[0018] According to some embodiments of the present application, the cargo platform includes a carrying frame, a carrying platform and a driving assembly, the carrying frame is connected to the lifting unit; the carrying platform is used to carry the battery clamp; the driving assembly is arranged on the carrying frame and connected to the carrying platform, the driving assembly is used to drive the carrying platform to move relative to the carrying frame along a first direction, and the first direction is perpendicular to the vertical direction.

[0019] In the above scheme, the loading platform includes a load frame, a loading platform and a driving assembly. The driving assembly can drive the loading platform to move along a first direction relative to the loading frame, so that the loading platform can be extended or retracted relative to the loading frame, thereby realizing the docking and loading and unloading operation of the loading platform and the corresponding target bin of the corresponding shelf.

[0020] According to some embodiments of the present application, the rotary lifting device also includes a righting part and a plurality of righting frames. The righting part is rotatably arranged at one end of the column away from the base. The rotation axis of the righting part is coaxially arranged with the rotation axis of the column. The righting part has a plurality of slots along its circumference. The plurality of righting frames are spaced apart along the outer circumference of the column, and the righting frames are arranged between the righting part and the shelf. One end of the righting frame is used to be connected to the shelf, and the other end of the righting frame is provided with a plug-in part for being inserted into the slot.

[0021] In the above scheme, when the cargo platform is raised or lowered to the top of the column and the column rotates, the deflection of the column is large and the stability is relatively low. In order to improve the stability of the column and reduce the risk of column collapse, a straightening part and a straightening frame are arranged on the top of the column, one end of the straightening frame is fixedly connected to the shelf, and the other end of the straightening frame is plugged into the slot of the straightening part through the plug-in part. In this way, when the column rotates, multiple straightening frames can provide support force to the straightening part in the circumferential direction, which can also be understood as multiple straightening frames providing support force to the top of the column. The stability of the column is higher, the probability of column collapse is reduced, and the operation of the rotating lifting device is safer.

[0022] According to some embodiments of the present application, the rotary lifting device further includes an anti-falling unit, which is used to control the cargo platform to hold the column tightly after the cargo platform stalls.

[0023] In the above scheme, through the setting of the anti-fall unit, the anti-fall unit can control the cargo platform and the column to hold tightly after the cargo platform stalls, reducing the risk of the cargo platform directly stalling and falling, and improving the safety of the cargo platform during operation.

[0024] According to some embodiments of the present application, the anti-fall unit includes a third guide rail, a safety clamp and a trigger assembly, the third guide rail is extended in the vertical direction and is arranged on the column; the safety clamp is installed on the cargo platform, and the safety clamp has a clamping state and a loosened state relative to the third guide rail; the trigger assembly is connected to the brake pad in the safety clamp, and the trigger assembly is used to control the safety clamp to switch between the clamping state and the loosened state; wherein, when the safety clamp is in the clamping state, the safety clamp is locked with the third guide rail to prevent the cargo platform and the third guide rail from moving relative to each other; when the safety clamp is in the loosened state, the cargo platform can move in the vertical direction relative to the third guide rail.

[0025] In the above scheme, through the setting of the trigger component, the trigger component can control the safety clamp according to the operating state of the cargo platform. When the cargo platform stalls during operation, such as when the lifting speed of the cargo platform exceeds the preset speed, the trigger component controls the safety clamp to switch to the clamping state, and the brake pads in the safety clamp are locked with the third guide rail to prevent the cargo platform and the third guide rail from moving relative to each other, thereby reducing the risk of the cargo platform falling. When the cargo platform runs within the preset speed, the safety clamp will not lock with the third guide rail, and the cargo platform will operate normally.

[0026] According to some embodiments of the present application, a pressure-sensitive carpet is laid on the base, and the pressure-sensitive carpet is arranged between the column and the shelf.

[0027] In the above scheme, by arranging a pressure-sensitive carpet on the base, the pressure-sensitive carpet can transmit pressure signals to the controller and take necessary measures to ensure the safety of people on the pressure-sensitive carpet.

[0028] In a second aspect, an embodiment of the present application further provides a battery manufacturing device, the battery manufacturing device comprising the rotating lifting device of any of the aforementioned embodiments, the rotating lifting device being used for transporting battery clamps.

[0047] During the battery manufacturing process, a stacker is required to transport battery fixtures, which contain battery cells. The battery fixtures are transported to the corresponding shelves’ bins by the stacker for battery performance testing. However, conventional stackers have limited rotation range and are distributed at intervals along the process direction. They generally load and unload materials directly, resulting in a large space occupied by the factory. For multiple circularly distributed shelves, although space can be saved, conventional stackers cannot cope well with the loading and unloading operations of multiple circularly distributed shelves. Moreover, for multiple circularly distributed shelves, the traditional stacker has a complex structure, which is not conducive to the actual transportation application of battery fixtures.

[0048] In view of this, in order to solve the problem that the existing stacker cannot realize the material picking and placing operation of the battery clamps on multiple shelves distributed in a ring, the embodiment of the present application provides a rotary lifting device, which can be applied to the material picking and placing operation of multiple shelves distributed in a ring.

[0049] In such a rotary lifting device, the lifting unit can drive the cargo platform to perform lifting and lowering movements in the vertical direction, thereby realizing the picking and placing operations of battery clamps in different positions in the height direction of the shelf. By providing a rotating unit on the base, the rotating unit can drive the column to perform circular motion around its axis, thereby driving the cargo platform to perform rotational motion in the circumferential direction, thereby realizing full coverage of multiple shelves distributed in a ring. That is, with the cooperation of the rotating unit and the lifting unit, the cargo platform can be driven to perform rotation and lifting movements, and the cargo platform can cooperate with different positions in the vertical direction of multiple shelves distributed in the peripheral direction of the column to realize the picking and placing operations of the battery clamps, and the structure is simple and easy to implement.

[0051] The base 10 refers to a seat structure that provides bearing for the rotary lifting device 100, and the base 10 may be a reinforced concrete structure, a concrete structure, or a support plate structure, etc. Of course, a plurality of shelves 200 in the peripheral direction of the column 20 may also be arranged on the base 10 and spaced apart on the peripheral side of the column 20.

[0052] The column 20 refers to a column structure disposed on the base 10 and extending in the vertical direction. The column 20 is installed for the lifting unit 50, and the lifting unit 50 drives the cargo platform 40 to move in the vertical direction, that is, along the height direction of the column 20. The column 20 can be a steel frame structure, a steel column 20 or a column structure of other materials.

[0053] A ladder 80 may be provided on the column 20 , and the ladder 80 can be used for workers to climb up, so as to facilitate maintenance of equipment such as a drive device on the column 20 .

[0054] Exemplarily, the column 20 is a steel frame structure, and the column 20 includes multiple steel columns and multiple steel beams, and the multiple steel columns and multiple steel beams are welded to form a steel frame structure. The lower end of the column 20 is connected to the base 10, and the column 20 is extended in the vertical direction. The height of the column 20 is not less than the height of the shelf 200, so as to meet the vertical travel of the cargo platform 40 and realize the material picking and placing operation of the battery clamps at different positions in the height direction of the shelf 200.

[0055] The rotating unit 30 refers to a rotating drive mechanism that can provide rotating power to the column 20. The rotating unit 30 is arranged on the base 10, and the rotating unit 30 drives the column 20 to rotate in a circumferential direction relative to the base 10. The rotating unit 30 can be a rotating mechanism of a rotating motor with a bearing or a worm gear mechanism, etc. The specific structural type of the rotating unit 30 can be determined according to actual conditions.

[0056] The first driving member 31 refers to a rotating driving component that provides rotational power to the column 20. The first driving member 31 may be a rotating motor. Specifically, the first driving member 31 may be a three-phase asynchronous servo motor.

[0057] The first driving member 31 may be provided with a linear measurement barcode sensor with a measurement accuracy of ±0.2 mm, which is conducive to detecting the rotation amount of the column 20 and the rotation accuracy of the column 20 is higher.

[0058] The slewing bearing 32 is also called a turntable bearing, or a rotating bearing or a slewing bearing. The slewing bearing 32 is arranged on the base 10, the inner ring of the slewing bearing 32 is fixed to the base 10, the outer ring of the slewing bearing 32 is drivingly connected to the first driving member 31, and the column 20 is fixedly connected to the outer ring of the slewing bearing 32. Under the action of the first driving member 31, the column 20 is driven to rotate. Of course, the outer ring of the slewing bearing 32 can also be fixed to the base 10, the inner ring of the slewing bearing 32 is drivingly connected to the first driving member 31, and the column 20 is fixedly connected to the inner ring of the slewing bearing 32. Under the action of the first driving member 31, the column 20 is driven to rotate.

[0059] The output shaft of the first driving member 31 is provided with a transmission gear. When the first driving member 31 is connected to the outer ring of the slewing bearing 32, the outer ring of the slewing bearing 32 is correspondingly provided with teeth, that is, the outer ring of the slewing bearing 32 has a gear ring. The transmission gear of the output shaft of the first driving member 31 meshes with the teeth of the outer ring of the slewing bearing 32, so that the first driving member 31 is driven and connected with the slewing bearing 32, and the transmission stability and precision are high.

[0060] The lifting unit 50 refers to a lifting structure provided on the column 20 to provide lifting power to the cargo platform 40. The lifting unit 50 can be a variety of lifting mechanisms. For example, the lifting unit 50 can be a linear drive mechanism such as a gear rack mechanism, a synchronous belt 52 wheel mechanism, a screw nut pair mechanism or a transmission chain mechanism. The specific structure of the lifting unit 50 can be determined according to actual conditions.

[0061] The cargo platform 40 refers to a load-bearing mechanism that can provide a load-bearing function for the battery clamp. The battery clamp can be equipped with a battery cell or a battery. It should be noted that: Figure 2 Schematically shown is a state where a cargo platform 40 is at the bottom and the top of the column 20 , that is, a cargo platform 40 is provided on the column 20 . Figure 2 The two cargo platforms 40 in the figure are actually schematic diagrams of two states of a cargo platform 40 at the top and bottom of the column 20.

[0062] Please refer to Figure 1 , multiple shelves 200 are distributed in a ring on the outer peripheral side of the rotary lifting device 100, and one or more of the multiple shelves 200 provide the function of conveying battery fixtures, which can be referred to as the first shelf here, and the shelf 200 that can be tested is the second shelf. It can be understood that the external conveying device or robot conveys the battery fixture clamped with battery cells to the first shelf, and the cargo platform 40 of the rotary lifting device can take the battery fixture from the bin of the first shelf, and under the action of the rotary lifting device, carry the battery fixture to the corresponding bin of the corresponding second shelf for testing; or, the cargo platform 40 can remove the battery fixture of the corresponding second shelf after the test is completed and transfer it to the next station, and the next station can be the third shelf, and the third shelf can temporarily store the battery fixture after the test is completed for transportation and transfer by the external transfer device.

[0063] In this solution, a plurality of shelves 200 are spaced apart in the peripheral direction of the rotary lifting device 100, and a plurality of positions are spaced apart in the vertical direction on each shelf 200, and the positions can be used to place battery clamps. The rotary lifting device is suitable for the picking and placing of battery clamps on a plurality of shelves 200 distributed in an annular manner. The lifting unit 50 is provided on the column 20, and the lifting unit 50 can drive the cargo platform 40 to perform lifting and lowering movement in the vertical direction, thereby realizing the picking and placing of battery clamps in different positions in the height direction of the shelf 200. The base 10 is provided with a rotating unit 30, which can drive the column 20 to perform circular motion around its axis, thereby driving the cargo platform 40 to perform circumferential rotational motion, and can achieve full coverage of multiple shelves 200 distributed in an annular direction. The slewing bearing 32 can provide support for the column 20. Under the action of the first driving member 31, the first driving member 31 drives the column 20 to rotate through the slewing bearing 32, which can make the column 20 more stable during rotation and improve the stability of the cargo platform 40 during rotation. That is, under the cooperation of the rotating unit 30 and the lifting unit 50, the cargo platform 40 can be driven to achieve rotation and lifting actions. The cargo platform 40 can cooperate with different positions in the vertical direction of multiple shelves 200 distributed in the peripheral direction of the column 20 to achieve the material picking and placing operation of the battery clamp, and the structure is simple and easy to implement.

[0064] According to some embodiments of the present application, the lifting unit 50 includes two pulleys 51, a transmission member and a second driving member 53. The two pulleys 51 are spaced apart on the column 20 in the vertical direction, and the pulleys 51 are rotatably installed on the column 20; the transmission member is sleeved on the two pulleys 51, the transmission member is connected to the pulleys 51 for transmission, and the cargo platform 40 is connected to the transmission member; the second driving member 53 is arranged on the column 20, and the second driving member 53 is used to drive any one of the two pulleys 51 to rotate, so as to drive the transmission member to move in the vertical direction.

[0065] The pulley 51 is a component widely used in mechanical transmission, which realizes power transmission by cooperating with a belt, a synchronous belt 52 or a chain. There are many types of pulleys 51, including synchronous belt 52 wheels and V-belt pulleys 51. The pulley 51 can be rotatably mounted on the column 20 through a bearing. The transmission member can be a transmission chain, a synchronous belt 52 or a wire rope 7313. When the transmission member is a transmission chain or a synchronous belt 52, the outer ring of the transmission member, which is the pulley 51, can be provided with teeth, and the transmission member is meshed with the teeth of the pulley 51 to realize the transmission connection between the transmission member and the pulley 51.

[0066] The second driving member 53 may be a servo motor, and the second driving member 53 may be driven and connected to the pulley 51 through a gear, thereby driving the pulley 51 to rotate. The two pulleys 51 are a first synchronous belt 52 wheel and a second synchronous belt 52 wheel, and the first synchronous belt 52 wheel is driven and connected to the second driving member 53 to realize the rotation of the pulley 51, and the second synchronous belt 52 wheel rotates synchronously after the transmission of the transmission member. The first synchronous belt 52 wheel and the second synchronous belt 52 wheel are respectively installed at the upper end and the lower end of the column 20.

[0067] By adopting the lifting unit 50 as a pulley mechanism, the second driving member 53 is installed on the column 20, and the second driving member 53 drives one of the two pulleys 51 to rotate. Under the rotation of the pulley 51, the transmission member is driven to move, and the cargo platform 40 is connected to the transmission member. The transmission member drives the cargo platform 40 to perform lifting and lowering movements. Under the transmission action of the transmission member, a relatively stable lifting power is provided to the cargo platform 40.

[0068] According to some embodiments of the present application, the transmission member includes a synchronous belt 52 , which is meshed with a pulley 51 .

[0069] The synchronous belt 52 is also called a synchronous toothed belt, which works in a flexible transmission mode, similar to common belt transmission modes such as V-belts and flat belts. At the same time, since there is no relative sliding between the synchronous belt 52 and the pulley 51, the transmission ratio is more constant, and it is widely used in industrial production processes. The synchronous belt 52 can be made of rubber.

[0070] It is understandable that the battery cells clamped by the battery clamp have high requirements for the transportation environment. If the transmission parts are made of steel wire ropes or transmission chains, the friction between the steel wire ropes or transmission chains and the pulley 51, that is, the friction between metal and metal, can easily introduce metal particles or metal powder, which may affect the performance of the battery.

[0071] By using a synchronous belt 52 as a transmission part, compared to using a wire rope or a transmission chain as a transmission part, the synchronous belt 52 is non-metallic, and the friction between the synchronous belt 52 and the pulley 51 will not produce metal powder, thereby reducing the probability of metal powder introduction and meeting the transportation environment requirements of the battery clamp.

[0072] According to some embodiments of the present application, a counterweight 54 is disposed on the synchronous belt 52 , and the counterweight 54 and the cargo platform 40 are respectively disposed on opposite sides of the synchronous belt 52 .

[0073] The counterweight 54 is a counterweight component that adds weight to the synchronous belt 52 to balance the load of the cargo platform 40 during the ascending process, that is, the counterweight 54 can reduce the lifting load of the second driving member 53. The synchronous belt 52 is an annular belt body, and the counterweight 54 and the cargo platform 40 can be connected to opposite sides of the synchronous belt 52 respectively.

[0074] By arranging a counterweight 54 on the synchronous belt 52, when the synchronous belt 52 drives the cargo platform 40 to rise, the counterweight 54 can provide downward gravity to the other side of the synchronous belt 52, thereby reducing the load of the second driving component 53 in the process of driving the cargo platform 40 to rise, reducing the working power of the second driving component 53, and also playing a certain protective role for the second driving component 53.

[0075] According to some embodiments of the present application, the lifting unit 50 also includes a first guide rail 55, which extends in the vertical direction and is arranged on the column 20. The cargo platform 40 slides with the first guide rail 55, and the first guide rail 55 is used to guide the cargo platform 40 to move in the vertical direction.

[0076] Compared with the column 20, the cargo platform 40 is a cantilever beam structure. The first guide rail 55 refers to a guide rail component that provides a guiding function for the cargo platform 40 during the lifting process. In order to improve the lifting stability of the cargo platform 40, the first guide rail 55 can be a dovetail track or a wedge-shaped track. The cargo platform 40 cooperates with the first guide rail 55, and the cargo platform 40 cannot be separated from the first guide rail 55. The first guide rail 55 can provide a certain support force for the cargo platform 40, thereby improving the stability and safety of the cargo platform 40 during the lifting process.

[0077] By setting the first guide rail 55, the first guide rail 55 and the cargo platform 40 are slidably matched. In the process of the transmission member driving the cargo platform 40 to rise and fall, the first guide rail 55 can provide a guiding function for the cargo platform 40, so that the cargo platform 40 is more stable during the lifting process.

[0078] According to some embodiments of the present application, the second driving member 53 is disposed at one end of the column 20 close to the base 10 .

[0079] By arranging the second driving member 53 on one end of the column 20 close to the base 10 , the installation height of the second driving member 53 is lowered, which reduces the maintenance difficulty of the second driving member 53 and facilitates the maintenance and replacement of the second driving member 53 .

[0080] According to some embodiments of this application, please combine Figures 4 to 7 The cargo platform 40 includes a load-bearing frame 41, a load-bearing platform 42 and a driving assembly 43. The load-bearing frame 41 is connected to the lifting unit 50; the load-bearing platform 42 is used to carry the battery clamp; the driving assembly 43 is arranged on the load-bearing frame 41 and connected to the load-bearing platform 42. The driving assembly 43 is used to drive the load-bearing platform 42 to move along a first direction relative to the load-bearing frame 41, and the first direction is perpendicular to the vertical direction.

[0081] The driving assembly 43 refers to a driving component that provides push-pull functions for the bearing platform 42. The driving assembly 43 can be a linear driving mechanism such as a cylinder, a hydraulic cylinder, a screw-nut pair mechanism, a gear rack mechanism, or an electric push rod. The specific structure of the driving assembly 43 can be determined according to actual conditions.

[0082] The driving assembly 43 can drive the platform 42 to move relative to the carrier 41, so that the platform 42 can extend or retract relative to the carrier 41. When the platform 42 extends, the platform 42 can enter the bin of the shelf 200 to place the battery fixture into the bin or take out the battery fixture in the bin. The bins of the shelf 200 can be provided with corresponding loading mechanisms. After the platform 42 enters the bin, the loading mechanism can place the battery fixture in the bin into the platform 42; or, after the platform 42 carries the battery fixture and pushes it into the corresponding bin, the loading mechanism takes out the battery fixture.

[0083] The carrier frame 41 is provided with a second guide rail extending in the first direction, and the carrier platform 42 is slidably matched with the second guide rail. The second guide rail is a guide component that provides a guiding function for the carrier platform 42. The cross-sectional shape of the second guide rail can be a dovetail shape or an inverted trapezoidal shape, so that the carrier platform 42 can only slide along the extension direction of the second guide rail, and the carrier platform 42 cannot be separated from the second guide rail. By providing the second guide rail on the carrier frame 41, the second guide rail can provide a guiding function for the movement of the carrier platform 42, so that the carrier platform 42 is more stable and reliable during the movement process.

[0084] The first direction is perpendicular to the vertical direction, and the first direction may be the length direction of the cargo platform 40 , that is, the distribution direction of the cargo platform 40 and the shelf 200 .

[0085] The loading platform 40 includes a load-bearing frame 41, a load-bearing platform 42 and a driving assembly 43. The driving assembly 43 can drive the load-bearing platform 42 to move along a first direction relative to the load-bearing frame 41, so that the load-bearing platform 42 can be extended or retracted relative to the load-bearing frame 41, thereby realizing the docking and loading and unloading operation of the load-bearing platform 42 and the corresponding target bin of the corresponding shelf 200.

[0086] According to some embodiments of this application, please combine Figures 1 to 3 The rotary lifting device 100 also includes a straightening portion 60 and a plurality of straightening frames 62. The straightening portion 60 is rotatably arranged at one end of the column 20 away from the base 10. The rotation axis of the straightening portion 60 is coaxially arranged with the rotation axis of the column 20. The straightening portion 60 has a plurality of slots 61 along its circumference; the plurality of straightening frames 62 are spaced apart along the outer circumference of the column 20, and the straightening frames 62 are arranged between the straightening portion 60 and the shelf 200; one end of the straightening frame 62 is used to be connected to the shelf 200, and the other end of the straightening frame 62 is provided with a plug-in portion 621 for being inserted into the slot 61.

[0087] The straightening portion 60 can be rotatably mounted on the top of the column 20 via a bearing. The straightening portion 60 is an annular structure, and a plurality of slots 61 are distributed on the straightening portion 60 at intervals along the circumferential direction.

[0088] The righting frame 62 refers to a frame structure that provides support for the righting portion 60. One end of the righting frame 62 is fixedly connected to the top of the shelf 200, and the plug-in portion 621 at the other end of the righting frame 62 is plugged and matched with the righting portion 60 to achieve support for the column 20. Multiple righting frames 62 are distributed at intervals along the circumferential direction on the outer peripheral side of the column 20, and the multiple righting frames 62 cooperate with the righting portion 60 together to achieve support for the column 20 in the circumferential direction, that is, to provide support for the top of the column 20.

[0089] When the cargo platform 40 is lifted to the top of the column 20, the column 20 rotates, and the deflection of the column 20 is large, and the stability is relatively low. In order to improve the stability of the column 20 and reduce the risk of collapse of the column 20, a straightening portion 60 and a straightening frame 62 are provided on the top of the column 20, one end of the straightening frame 62 is fixedly connected to the shelf 200, and the other end of the straightening frame 62 is plugged into the slot 61 of the straightening portion 60 through the plug-in portion 621. In this way, when the column 20 rotates, multiple straightening frames 62 can provide support force to the straightening portion 60 in the circumferential direction, which can also be understood as multiple straightening frames 62 providing support force to the top of the column 20. The stability of the column 20 is higher, the probability of collapse of the column 20 is reduced, and the operation of the rotating lifting device is safer.

[0090] According to some embodiments of the present application, the rotary lifting device 100 further includes an anti-falling unit 70 , and the anti-falling unit 70 is used to control the cargo platform 40 to be tightly held with the column 20 after the cargo platform 40 stalls.

[0091] The anti-fall unit 70 refers to a braking component that can provide a braking function to the cargo platform 40 after stalling. Of course, a buffer can be correspondingly provided on the base 10, which can cooperate with the anti-fall unit 70 to play a double insurance function, and the buffer can provide a buffering effect for the cargo platform 40. The buffer can be directly purchased and is an existing technology.

[0092] By setting the anti-fall unit 70, the anti-fall unit 70 can control the cargo platform 40 and the column 20 to hold tightly after the cargo platform 40 stalls, reducing the risk of the cargo platform 40 directly stalling and falling, and improving the safety of the cargo platform 40 during operation.

[0093] According to some embodiments of this application, please refer to Figure 8The anti-fall unit 70 includes a third guide rail 71, a safety clamp 72 and a trigger assembly 73. The third guide rail 71 extends along the vertical direction and is arranged on the column 20; the safety clamp 72 is installed on the cargo platform 40, and the safety clamp 72 has a clamping state and a loose state relative to the third guide rail 71; the trigger assembly 73 is connected to the brake pad 722 in the safety clamp 72, and the trigger assembly 73 is used to control the safety clamp 72 to switch between the clamping state and the loose state; wherein, when the safety clamp 72 is in the clamping state, the safety clamp 72 is locked with the third guide rail 71 to prevent the cargo platform 40 and the third guide rail 71 from moving relative to each other; when the safety clamp 72 is in the loose state, the cargo platform 40 can move in the vertical direction relative to the third guide rail 71.

[0094] The safety clamp 72 has a clamp body 721 with two wedge-shaped surfaces, and a brake pad 722 slidably disposed on the clamp body 721, and the third guide rail 71 is penetrated by the two brake pads 722. The trigger assembly 73 can be a variety of trigger mechanisms, for example, the trigger assembly 73 can be a controller to control the cylinder to act on the brake pad 722 in the safety clamp 72 to hold the third guide rail 71. Of course, the trigger assembly 73 can also be a mechanical mechanism to control the safety clamp 72 to hold the third guide rail 71, which depends on the actual situation.

[0095] Optionally, the trigger assembly 73 includes a first trigger assembly, and the first trigger assembly 73 is used in the case where the cargo platform 40 stalls. The first trigger assembly 73 includes a connecting rod assembly 732 and a speed limiter 731. The speed limiter 731 is a speed limiter 731 that can be directly purchased on the market, and can be a common speed limiter used in the elevator field. The speed limiter 731 may include a speed limiter body 7311, a speed limiter wheel 7312 and a wire rope 7313. The speed limiter wheels 7312 are rotatably arranged at both ends of the column 20, and the wire rope 7313 is wound around the two speed limiter wheels 7312. The wire rope 7313 is transmitted around the speed limiter wheel 7312.

[0096] The connecting rod assembly 732 includes a first connecting rod 7321, one end of which is connected to the wire rope 7313, and the other end of which is connected to the brake pad 722 in the safety clamp 72. Under normal operation, the wire rope 7313 can move up and down around the speed limiter wheel 7312. When the running speed of the cargo platform 40 exceeds the preset speed, such as after stalling, the speed limiter body 7311 holds the wire rope 7313 tightly, and the wire rope 7313 cannot continue to move around the speed limiter wheel 7312. If the cargo platform 40 continues to move downward, the brake pad 722 connected to the far end of the first connecting rod 7321 moves upward relative to the safety clamp 72, thereby holding the third guide rail 71, so that the cargo platform 40 cannot move downward relative to the third guide rail 71, thereby automatically achieving the braking of the cargo platform 40.

[0097] The trigger assembly 73 may further include a second trigger assembly, which is used when the synchronous belt 52 is broken. The second trigger assembly includes a second connecting rod 7322 and a third connecting rod 7323, one end of the second connecting rod 7322 is rotatably connected to the first connecting rod 7321, the third connecting rod 7323 is hinged to one end of the second connecting rod 7322, and the upper end of the third connecting rod 7323 is connected to a matching plate 7324.

[0098] A pressure block 733 is fixed on the synchronous belt 52 in the lifting unit, and a downwardly extending guide rod 7331 is provided at the bottom of the pressure block 733. A connecting plate 734 is fixedly connected to the cargo platform 40. The connecting plate 734 is hinged to the third connecting rod 7323, and the guide rod 7331 is passed through the connecting plate 734. The connecting plate 734 can slide relative to the guide rod 7331. A spring 735 is sleeved on the guide rod 7331. One end of the spring 735 abuts against the connecting block, and the other end abuts against the matching plate 7324. Under the normal operating state of the cargo platform 40, the spring 735 is in a compressed state. When the synchronous belt 52 breaks, the elastic force of the spring 735 is reset, driving the matching plate 7324 to move downward. After the matching plate 7324 moves downward, it drives the third connecting rod 7323 to swing downward, and the second connecting rod 7322 to swing upward. After the second connecting rod 7322 swings upward, it drives the first connecting rod 7321 to swing upward, thereby realizing the upward movement of the brake pad 722 in the safety clamp 72 relative to the safety clamp 72, so that the brake pad 722 holds the third guide rail 71 tightly, thereby braking the cargo platform 40.

[0099] Through the setting of the trigger component 73, the trigger component 73 can control the safety clamp 72 according to the operating state of the cargo platform 40. When the cargo platform 40 stalls during operation, such as when the lifting speed of the cargo platform 40 exceeds the preset speed, the trigger component 73 controls the safety clamp 72 to switch to the clamping state, and the brake pad 722 in the safety clamp 72 is locked with the third guide rail 71, preventing the cargo platform 40 from moving relative to the third guide rail 71, thereby reducing the risk of the cargo platform 40 falling. When the cargo platform 40 runs within the preset speed, the safety clamp 72 will not lock with the third guide rail 71, and the cargo platform 40 runs normally.

[0100] According to some embodiments of the present application, a pressure-sensitive carpet is laid on the base 10 , and the pressure-sensitive carpet is arranged between the column 20 and the shelf 200 .

[0101] Pressure sensitive carpet (also called safety carpet or safety mat) is a specially designed carpet, usually used in industrial automation, robot operation area, to provide additional safety protection. Its main function is to detect whether a person or object enters a specific area by sensing pressure changes, and trigger a safety response accordingly.

[0102] The pressure-sensitive carpet is electrically connected to the controller, and the controller can control the alarm to send out an alarm signal according to the signal triggered by the pressure-sensitive carpet. That is, after someone is on the pressure-sensitive carpet, the pressure-sensitive carpet triggers a signal and transmits it to the controller, and the controller can control the alarm to send out an alarm signal. Of course, the alarm signal can be of many types. For example, the alarm signal can be a conventional sound signal to alert the person on the pressure-sensitive carpet. Alternatively, the alarm signal is not a conventional sound signal, and the alarm signal can be an alarm instruction inside the control system, that is, the alarm signal can trigger the lifting unit 50 and / or the rotating unit 30 to stop the cargo platform 40 from descending, or reduce the rotation speed of the rotating unit 30, etc.

[0103] By arranging a pressure-sensitive carpet on the base 10, the pressure-sensitive carpet can transmit pressure signals to the controller and take necessary measures to ensure the safety of people on the pressure-sensitive carpet.

[0104] An embodiment of the present application further provides a battery manufacturing device, the battery manufacturing device comprising the rotating lifting device 100 of any of the aforementioned embodiments, the rotating lifting device 100 being used for transporting battery clamps.

[0105] In some embodiments, please refer to Figures 1 to 8 The rotary lifting device 100 includes a base 10, a column 20, a rotating unit 30, a cargo platform 40 and a lifting unit 50. The column 20 is extended and arranged on the base 10 in the vertical direction; the rotating unit 30 is arranged on the base 10 and connected to the column 20, and the rotating unit 30 is used to drive the column 20 to rotate around its axis; the cargo platform 40 is used to carry the battery clamp; the lifting unit 50 is arranged on the column 20, and the lifting unit 50 is connected to the cargo platform 40, and the lifting unit 50 is used to drive the cargo platform 40 to rise and fall in the vertical direction. The rotating unit 30 includes a first driving member 31 and a slewing bearing 32. The first driving member 31 is arranged on the base 10; the slewing bearing 32 is connected to the first driving member 31 and the column 20, and the first driving member 31 is used to drive the column 20 to rotate relative to the base 10. The lifting unit 50 includes two pulleys 51, a transmission member and a second driving member 53. The two pulleys 51 are spaced apart on the column 20 in the vertical direction, and the pulleys 51 are rotatably installed on the column 20; the transmission member is sleeved on the two pulleys 51, the transmission member is connected to the pulleys 51 for transmission, and the cargo platform 40 is connected to the transmission member; the second driving member 53 is arranged on the column 20, and the second driving member 53 is used to drive any one of the two pulleys 51 to rotate, so as to drive the transmission member to move in the vertical direction, and the transmission member includes a synchronous belt 52, and the synchronous belt 52 is meshed with the pulley 51.

[0106] The rotary lifting device 100 is suitable for the picking and placing of battery fixtures on multiple shelves 200 distributed in a ring. The lifting unit 50 is provided on the column 20, and the lifting unit 50 can drive the cargo platform 40 to perform lifting and lowering movements in the vertical direction, so as to realize the picking and placing of battery fixtures at different positions in the height direction of the shelf 200. The rotating unit 30 is provided on the base 10, and the rotating unit 30 can drive the column 20 to perform circular motion around its axis, thereby driving the cargo platform 40 to perform rotational motion in the circumferential direction, so as to realize full coverage of multiple shelves 200 distributed in a ring. That is, under the cooperation of the rotating unit 30 and the lifting unit 50, the cargo platform 40 can be driven to realize rotation and lifting movements, and the cargo platform 40 can cooperate with different positions in the vertical direction of multiple shelves 200 distributed in the peripheral direction of the column 20 to realize the picking and placing of battery fixtures, and the structure is simple and easy to realize. The slewing bearing 32 can provide support for the column 20. Under the action of the first driving member 31, the first driving member 31 drives the column 20 to rotate through the slewing bearing 32, which can make the column 20 more stable during rotation and improve the stability of the cargo platform 40 during rotation. By adopting the lifting unit 50 as a pulley 51 mechanism, the second driving member 53 is installed on the column 20, and the second driving member 53 drives one of the two pulleys 51 to rotate. Under the rotation of the pulley 51, the transmission member is driven to move, and the cargo platform 40 is connected to the transmission member. The transmission member drives the cargo platform 40 to perform lifting and lowering movements. Under the transmission action of the transmission member, a relatively stable lifting and lowering power is provided to the cargo platform 40. The synchronous belt 52 is non-metallic, and the friction between the synchronous belt 52 and the pulley 51 will not produce metal powder, which reduces the probability of metal powder introduction and meets the transportation environment requirements of the battery clamp.

[0107] In some embodiments, a counterweight 54 is provided on the synchronous belt 52, and the counterweight 54 and the cargo platform 40 are respectively provided on opposite sides of the synchronous belt 52. The lifting unit 50 further includes a first guide rail 55, which extends along the vertical direction and is provided on the column 20. The cargo platform 40 is slidably matched with the first guide rail 55, and the first guide rail 55 is used to guide the cargo platform 40 to move along the vertical direction. The second driving member 53 is provided at one end of the column 20 close to the base 10.

[0108] By arranging a counterweight 54 on the synchronous belt 52, when the synchronous belt 52 drives the cargo platform 40 to rise, the counterweight 54 can provide downward gravity to the other side of the synchronous belt 52, thereby reducing the load of the second driving member 53 in the process of driving the cargo platform 40 to rise, reducing the working power of the second driving member 53, and also playing a certain protective role for the second driving member 53. The first guide rail 55 is slidably matched with the cargo platform 40. When the transmission member drives the cargo platform 40 to rise and fall, the first guide rail 55 can provide a guiding function for the cargo platform 40, making the cargo platform 40 more stable during the lifting process. By arranging the second driving member 53 on the column 20 close to one end of the base 10, the installation height of the second driving member 53 is lower, which reduces the maintenance difficulty of the second driving member 53 and facilitates the maintenance and replacement of the second driving member 53.

[0109] In some embodiments, the cargo platform 40 includes a carrier 41, a carrier platform 42 and a driving assembly 43, the carrier 41 is connected to the lifting unit 50; the carrier platform 42 is used to carry the battery clamp; the driving assembly 43 is arranged on the carrier 41 and connected to the carrier platform 42, and the driving assembly 43 is used to drive the carrier platform 42 to move relative to the carrier 41 along a first direction, and the first direction is perpendicular to the vertical direction. The rotary lifting device 100 also includes a straightening portion 60 and a plurality of straightening frames 62, the straightening portion 60 is rotatably arranged at one end of the column away from the base 10, the rotation axis of the straightening portion 60 is coaxially arranged with the rotation axis of the column 20, and the straightening portion 60 has a plurality of slots 61 along its circumference; the plurality of straightening frames 62 are spaced apart along the outer circumference of the column 20, and the straightening frames 62 are arranged between the straightening portion 60 and the shelf 200; one end of the straightening frame 62 is used to connect with the shelf 200, and the other end of the straightening frame 62 is provided with a plug-in portion 621 for being inserted into the slot 61.

[0110] The driving assembly 43 can drive the loading platform 42 to move along the first direction relative to the loading frame 41, so that the loading platform 42 can be extended or retracted relative to the loading frame 41, so as to achieve the docking and unloading operation between the loading platform 42 and the corresponding target bin of the corresponding shelf 200. When the loading platform 40 is raised and lowered to the top of the column 20 and the column 20 rotates, the deflection of the column 20 is large and the stability is relatively low. In order to improve the stability of the column 20 and reduce the risk of collapse of the column 20. By arranging a straightening portion 60 and a straightening frame 62 on the top of the column 20, one end of the straightening frame 62 is fixedly connected to the shelf 200, and the other end of the straightening frame 62 is plugged into and matched with the slot 61 of the straightening portion 60 through the plug-in portion 621. In this way, when the column 20 rotates, multiple straightening frames 62 can provide supporting force to the straightening portion 60 in the circumferential direction. It can also be understood that multiple straightening frames 62 provide supporting force to the top of the column 20. The stability of the column 20 is higher, the probability of collapse of the column 20 is reduced, and the operation of the rotating lifting device is safer.

[0111] In some embodiments, the rotary lifting device 100 further includes an anti-falling unit 70, which is used to control the cargo platform 40 to hold the column 20 tightly after the cargo platform 40 stalls.

The third guide rail 71 extends along the vertical direction and is arranged on the column 20; the safety clamp 72 is installed on the cargo platform 40, and the safety clamp 72 has a holding state and a release state relative to the third guide rail 71; the trigger assembly 73 is used to control the safety clamp 72 to switch between the holding state and the release state; wherein, when the safety clamp 72 is in the holding state, the safety clamp 72 is locked with the third guide rail 71 to prevent the cargo platform 40 from moving relative to the third guide rail 71; when the safety clamp 72 is in the release state, the cargo platform 40 can move in the vertical direction relative to the third guide rail 71. A pressure-sensitive carpet is laid on the base 10, and the pressure-sensitive carpet is arranged between the column 20 and the shelf 200.

[0112] The anti-fall unit 70 can control the cargo platform 40 to hold the column 20 tightly after the cargo platform 40 stalls, reducing the risk of the cargo platform 40 directly stalling and falling, and improving the safety of the cargo platform 40 during operation. The trigger component 73 can detect the operating state of the cargo platform 40 and control the safety clamp 72. When the cargo platform 40 stalls during operation, such as when the lifting speed of the cargo platform 40 exceeds the preset speed, the trigger component 73 controls the safety clamp 72 to switch to the holding state, and the safety clamp 72 is locked with the third guide rail 71 to prevent the cargo platform 40 from moving relative to the third guide rail 71, thereby reducing the risk of the cargo platform 40 falling. If the cargo platform 40 runs within the preset speed, the safety clamp 72 will not lock with the third guide rail 71, and the cargo platform 40 will operate normally. The pressure-sensitive carpet can transmit the pressure signal to the controller and take necessary measures to ensure the safety of the personnel on the pressure-sensitive carpet.
