Description

Technical Field

[0001] This utility model relates to the field of battery transfer technology, and in particular to a rotary lifting device and battery transfer equipment. Background Technology

[0002] The battery production process involves multiple steps, and special transfer equipment is needed to transfer products between different steps. Depending on the structure of the equipment in each step, the transfer process requires lifting or turning the product to adjust its position.

[0003] In existing technologies, lifting and steering in battery transfer equipment are achieved by independent drive systems. That is, the product is first moved into the lifting system for lifting, and after reaching the designated height, it is then driven by the steering system to turn, thereby adjusting the product's position.

[0004] However, the independent setup of the lifting and steering systems means that during the transfer process, the height can only be adjusted first, and then the direction can be adjusted. When the height is adjusted again, the battery needs to be sent back to the original system, resulting in low efficiency during the transfer process. In addition, the two systems occupy different spaces, which also results in the entire equipment taking up a large space. Utility Model Content

[0005] The purpose of this invention is to provide a rotating lifting device and a battery transfer equipment, which solves the problem in the prior art that the lifting and rotating processes need to be carried out separately during the battery transfer process, resulting in reduced transfer efficiency and the two systems occupying a lot of space.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a rotary lifting device, which includes:

[0008] frame;

[0009] The lifting platform is slidably connected to the frame;

[0010] A rotary table, rotatably connected to the lifting platform;

[0011] A pull cord is provided on the rotary table and is used to support the battery;

[0012] A rotary drive component is disposed on the lifting platform and connected to the rotary platform to drive the rotary platform to rotate;

[0013] A lifting assembly is disposed on the frame and connected to the lifting platform to drive the lifting platform to lift the rotary table.

[0014] Optionally, the rotary table includes:

[0015] The base plate is rotatably connected to the lifting platform;

[0016] A support frame is provided on the base plate, and the pull cord is fixedly installed on the support frame and partially extends into the support frame.

[0017] Optionally, the rotary lifting device further includes:

[0018] A limiting bracket is slidably connected to the pull cord and can partially protrude from the pull cord after the battery enters the pull cord, so as to limit the position of the battery on the pull cord.

[0019] Optionally, the limiting frame includes:

[0020] Connecting seat, slidably connected to the pull cord;

[0021] A limiting roller is rotatably connected to the connecting seat and can abut against the battery to limit the position of the battery.

[0022] Optionally, the rotary table further includes:

[0023] A limit drive component is disposed on the pull belt and connected to the limit frame to drive the limit frame to slide.

[0024] Optionally, the lifting assembly includes:

[0025] A lifting belt is rotatably connected to the frame via pulleys;

[0026] A fixed base is fixed to the side of the lifting belt near the lifting platform, and the lifting platform is fixedly connected to the fixed base;

[0027] A counterweight is fixed to the side of the lifting belt away from the lifting platform;

[0028] A lifting drive component is connected to the pulley to drive the pulley to rotate.

[0029] Optionally, multiple lifting belts are distributed at intervals along the width direction of the lifting belt.

[0030] Optionally, the rotary lifting device further includes:

[0031] A buffer column is installed on the frame and can abut against the lifting platform. The buffer column can deform along the lifting direction of the lifting platform.

[0032] Optionally, the rotary lifting device further includes:

[0033] A scapegoat assembly is provided on the lifting assembly to lock the lifting assembly.

[0034] Secondly, this utility model also provides a battery transfer device, which includes:

[0035] Conveyor line, used to transport batteries;

[0036] The rotary lifting device as described in any one of the first aspects can connect the pull belt to the conveyor line to receive the battery.

[0037] The beneficial effects of this utility model are:

[0038] Firstly, by setting up a frame, with the lifting assembly housed within the frame and the rotary table and rotary drive unit mounted on the lifting platform, the lifting and rotation functions are integrated. When receiving batteries, the lifting assembly drives the lifting platform to rise and fall, causing the rotary table to align with the conveyor belt, allowing the conveyor belt to transport the batteries onto the conveyor belt. Once the batteries are fully inside the conveyor belt, the lifting assembly and rotary drive unit operate synchronously. The lifting assembly raises and lowers the rotary table to a specified height, while the rotary drive unit rotates the rotary table in a specified direction. Thus, this rotary lifting device can synchronously lift, lower, and rotate the conveyor belt carrying the batteries, allowing the batteries to be accurately adjusted to the designated position without repeated transport, effectively improving battery transfer efficiency. Furthermore, the integrated rotation and lifting functions on the frame allow for a centralized layout of the corresponding structures within the frame, effectively reducing space occupation and improving space utilization.

[0039] Secondly, when the battery transfer equipment is in use, after the battery is conveyed to the pull belt by the conveyor harness, the rotating lifting device can rotate and lift the battery synchronously, thereby quickly adjusting the battery's position and smoothly transferring the battery to the next process. This can effectively improve the battery transfer efficiency and reduce the overall space occupied by the battery transfer equipment. Attached Figure Description

[0053] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0054] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0057] This utility model discloses a rotary lifting device and a battery transfer device.

[0058] Reference Figures 1 to 4 The rotary lifting device includes a frame 1, a lifting platform 2, a rotating platform 3, a pull belt 4, a rotary drive component 5, and a lifting assembly 6. The lifting platform 2 is slidably connected to the frame 1; the rotating platform 3 is rotatably connected to the lifting platform 2; the pull belt 4 is disposed on the rotating platform 3 and is used to carry the battery; the rotary drive component 5 is disposed on the lifting platform 2 and connected to the rotating platform 3 to drive the rotating platform 3 to rotate; the lifting assembly 6 is disposed on the frame 1 and connected to the lifting platform 2 to drive the lifting platform 2 to move the rotating platform 3 up and down.

[0059] Specifically, the frame 1 has a frame structure, formed by welding together multiple column-shaped structures, and extends vertically, with its bottom wall fixed to the ground or other platform. Two vertically extending slide rails are spaced apart on the front side of the frame 1. The lifting platform 2 slides against the slide rails via a slider, and the lifting assembly 6 drives the lifting platform 2 to rise and fall vertically. The lifting assembly 6 can be any of a belt drive, chain drive, or screw drive structure, depending on the actual lifting requirements. Multiple height detectors 11 are spaced apart vertically on the frame 1. These height detectors can be slotted photoelectric sensors, which sense the lifting amplitude of the lifting platform 2 and control the start and stop of the lifting assembly 6. This prevents the lifting platform 2 from overshooting and colliding with the frame 1, and also allows for real-time monitoring of the lifting height of the lifting platform 2.

[0060] A rotating platform 3 is installed on the top wall of the lifting platform 2. The rotating platform 3 is rotatably connected to the lifting platform 2 via a rotating bearing. A rotating drive component 5, which can be a servo motor, is installed on the lifting platform 2. It can drive the rotating platform 3 to rotate to any angle via the bearing. A pull cord 4 is installed above the rotating platform 3. The pull cord 4 is detachably connected to the rotating platform 3 to allow for the selection of different types of pull cord 4 according to different battery models. The specific interface of the pull cord 4 can refer to the prior art, and this utility model does not limit it in this regard.

[0061] By setting up a frame 1, with the lifting assembly 6 housed within it, and the rotating platform 3 and rotating drive 5 mounted on the lifting platform 2, the lifting and rotating functions are integrated. When receiving a battery, the lifting assembly 6 drives the lifting platform 2 to rise and fall, causing the rotating platform 3 to align the conveyor belt 4 with the transport process. The transport process then transfers the battery onto the conveyor belt 4. Once the battery is fully inside the conveyor belt 4, the lifting assembly 6 and rotating drive 5 move synchronously. The lifting assembly 6 raises and lowers the rotating platform 3 to a specified height, while the rotating drive 5 drives the rotating platform 3 to rotate in a specified direction. Thus, this rotary lifting device can synchronously raise, lower, and rotate the conveyor belt 4 carrying the battery, allowing the battery to be accurately adjusted to the specified position without repeated transport, effectively improving battery transfer efficiency. Furthermore, the integrated rotation and lifting functions on the frame 1 allow for a centralized layout of the corresponding structures within the frame 1, effectively reducing space occupation and improving space utilization.

[0062] Optionally, the rotary table 3 includes a base plate 31 and a support frame 32. The base plate 31 is rotatably connected to the lifting platform 2; the support frame 32 is disposed on the base plate 31, and the pull cable 4 is fixedly installed on the support frame 32 and partially extends into the support frame 32.

[0063] Specifically, the bottom wall of the base plate 31 is rotatably connected to the top wall of the lifting platform 2 via bearings, and a support frame 32 is fixedly connected to the top wall of the base plate 31. The support frame 32 includes two opposing upright plates located at the edge of the base plate 31, forming a space between the two upright plates to accommodate the pull belt 4. The top walls of the upright plates are fixedly connected to the pull belt 4. The fixed connection described above can be achieved by means of screw connection, snap-fit, adhesive bonding, or welding.

[0064] By setting the base plate 31 and the support frame 32, on the one hand, the rotary table 3 and the lifting plate can be rotatably connected, and on the other hand, a space can be formed above the base plate 31 to accommodate the pull wire 4, so that the pull wire 4 can be smoothly fixed on the rotary table 3. Furthermore, part of the structure of the pull wire 4 extends into the support frame 32, so that the center of gravity of the pull wire 4 and the rotary table 3 as a whole is low, ensuring that it remains stable during rotation.

[0065] Optionally, the rotary lifting device also includes a limiting frame 33. The limiting frame 33 is slidably connected to the pull belt 4 and can partially protrude from the pull belt 4 after the battery enters the pull belt 4, so as to limit the position of the battery on the pull belt 4.

[0066] Specifically, limit baffles are provided on the left and right sides of the frame of the pull cord 4, which can guide and limit the battery in the left and right directions. A limit frame 33 is provided on the front and rear sides of the frame of the pull cord 4. The limit frame 33 can slide down before the battery enters to open the pull cord 4, and when the battery is fully inside, the limit frame 33 can protrude to restrict the battery's position. The limit frame 33 can be driven by a driving element, or it can be driven by an elastic structure, that is, it can slide down when the battery enters the pull cord 4, and automatically move upward after the battery enters, or it can be manually operated by a worker. This invention does not specifically limit the specific operation of the limit frame 33.

[0067] Optionally, the limiting frame 33 includes a connecting seat and a limiting roller. The connecting seat is slidably connected to the pull belt 4; the limiting roller is rotatably connected to the connecting seat and can abut against the battery to limit the position of the battery.

[0068] Specifically, the connecting seat can slide relative to the frame of the pull belt 4. The sliding can be achieved by the cooperation of the slide rail and the slider, or directly by the driving element such as the cylinder. A limiting roller can be set at the upper end of the connecting seat. The axis of the limiting roller is parallel to the width direction of the pull belt 4. In this embodiment, the pull belt 4 adopts a four-channel conveyor pull belt 4, and two limiting rollers are set at intervals along its axis.

[0069] After the battery is fully inserted into the pull belt 4, the connecting seat can move upward, thereby causing the limiting roller to protrude out of the pull belt 4, so that the limiting roller can form a corresponding contact with the battery to limit the position of the battery and ensure the stability of the battery. The limiting roller can rotate, thereby reducing the friction between the limiting roller and the battery, so as to reduce the possibility of the limiting roller wearing the battery during the rising or falling process.

[0070] Optionally, the rotary table 3 also includes a limit drive member 34. The limit drive member 34 is disposed on the pull line 4 and connected to the limit frame 33 to drive the limit frame 33 to slide.

[0071] Specifically, a guide plate is installed on the frame of the pull belt 4, and a guide rail is installed on the guide plate. The connecting seat slides with the guide rail via a slider. The limiting drive component 34 is fixed on the guide plate and is a cylinder. The piston rod of the cylinder can form a snap-fit ​​engagement with the connecting seat, so that when the piston rod extends or retracts, it can drive the connecting seat to rise and fall. In this way, after the battery enters the pull belt 4, the limiting drive component 34 can automatically push the limiting frame 33 to extend, thereby improving the overall automation level.

[0072] Optionally, the lifting assembly 6 includes a lifting belt 61, a fixed base 62, a counterweight 63, and a lifting drive component 64. The lifting belt 61 is rotatably connected to the frame 1 via a pulley; the fixed base 62 is fixed to the side of the lifting belt 61 near the lifting platform 2, and the lifting platform 2 is fixedly connected to the fixed base 62; the counterweight 63 is fixed to the side of the lifting belt 61 away from the lifting platform 2; the lifting drive component 64 is connected to the pulley to drive the pulley to rotate.

[0073] Specifically, a pulley is rotatably connected to both the upper and lower ends of the frame 1. The two pulleys are arranged opposite each other, and a lifting belt 61 is fitted onto the two pulleys. The lifting belt 61 is a synchronous belt, and the pulleys are synchronous pulleys. The drive unit can be connected to either pulley to drive the lifting belt 61 to rotate. The lifting drive unit 64 can be a servo motor or a self-locking motor.

[0074] A fixed base 62 is fixedly connected to the side of the lifting belt 61 near the lifting platform 2. The fixed base 62 is plate-shaped and extends in a vertical plane. One side of the fixed base 62 is directly fixedly connected to the lifting platform 2, while the other side slides with a slide rail on the frame 1 via a slider. The fixed connection can be achieved by any of the following methods: screw connection, snap-fit, welding, or bonding. A counterweight 63 is fixedly installed on the other side of the lifting belt 61. The counterweight 63 and the fixed base 62 are located on opposite sides of the frame 1.

[0075] When lifting is required, the lifting drive 64 is activated to drive the pulley to rotate. The pulley drives the lifting belt 61 to rotate, and the lifting belt 61 synchronously drives the fixed seat 62 and the counterweight 63 to rise and fall, thereby ensuring that the force on both sides is even, so that the lifting platform 2 set on the fixed seat 62 can rise and fall smoothly, improving the stability and safety of the battery transfer process.

[0076] Optionally, multiple lifting belts 61 are distributed at intervals along the width direction of the lifting belts 61.

[0077] Specifically, multiple lifting belts 61 can be spaced apart along the width of the frame 1, while only one lifting drive unit 64 can be provided. This drive unit can synchronously drive the pulleys of the multiple lifting belts 61, so that the multiple lifting belts 61 can rotate synchronously, thereby ensuring that the fixed base 62 is subjected to uniform force. In this embodiment, three lifting belts 61 can be spaced apart. In other embodiments, the number of lifting belts 61 can be designed according to the actual dimensions of the frame 1 and the lifting platform 2, and this utility model does not impose any limitation.

[0078] Optionally, the rotary lifting device further includes a buffer column 7. The buffer column 7 is disposed on the frame 1 and can abut against the lifting platform 2, and the buffer column 7 can deform along the lifting direction of the lifting platform 2.

[0079] Specifically, buffer columns 7 are provided on the two opposite walls at the upper and lower ends of the frame 1. The buffer column 7 includes a fixed cylinder and a buffer elastic element. The fixed cylinder is fixed on the frame 1, and the buffer elastic element is fixed on the end face of the fixed cylinder. The end of the buffer elastic element away from the fixed cylinder can abut against the lifting platform 2 and deform. The buffer elastic element can be a columnar structure made of elastic material, or it can be a spring, etc. This utility model does not limit this.

[0080] By setting up a buffer column 7, when the lifting platform 2 is raised to its limit position, the lifting platform 2 will come into contact with the buffer column 7. The deformation generated by the buffer column 7 will buffer the displacement of the lifting platform 2, thereby reducing the possibility of the lifting platform 2 colliding with other structures of the frame 1.

[0081] Optionally, the rotary lifting device also includes a scapegoat assembly 8. The scapegoat assembly 8 is disposed on the lifting assembly 6 for locking the lifting assembly 6.

[0082] Specifically, multiple belt breakage detectors 12 are installed on the frame 1, which can detect whether the pull belt 4 has broken. If a breakage is detected, an alarm can be triggered, such as a voice alarm or a light alarm. At this time, the scapegoat assembly 8 locks the lifting assembly 6. The scapegoat assembly 8 is fixed to the side of the fixed base 62 near the lifting platform 2. The fixed base 62 has a through hole for the scapegoat assembly 8 to be inserted. The frame 1 also has a corresponding inspection hole. When the rotary lifting device is inspected and maintained, the scapegoat assembly 8 can pass through the through hole and be inserted into the inspection hole to lock the lifting assembly 6, so as to ensure that the lifting platform 2 will not rise or fall during the maintenance process.

[0083] The battery transfer equipment includes a conveyor line and a rotary lifting device as described above. The conveyor line is used to transport batteries; the rotary lifting device connects the pull belt 4 to the conveyor line to receive the batteries.

[0084] When the battery transfer equipment is in use, after the battery is conveyed onto the pull belt 4 by the conveyor harness, the rotating lifting device can rotate and lift the battery synchronously, thereby quickly adjusting the battery's position and smoothly transferring the battery to the next process. This can effectively improve the battery transfer efficiency and reduce the overall space occupied by the battery transfer equipment.

[0085] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
