Technical Field

[0001] This utility model relates to the field of battery pack production and transportation technology, and in particular to a heavy-duty turntable and battery pack transportation production line for a battery pack transport production line. Background Technology

[0002] With the development of new energy vehicles, the demand for them is constantly increasing, and consequently, the demand for their internal power supply structure—the battery pack—is also constantly rising. Currently, due to the need for high-capacity battery packs, Cell-to-Pack (CTP) technology is being used more extensively, and to achieve greater driving range, battery packs are becoming larger and heavier. Therefore, battery pack transport production lines are gradually being upgraded to heavy-duty roller conveyors to support the battery packs. However, within the battery pack production line, there are still devices that require steering and transporting the battery packs. How to achieve the steering and transport of relatively heavy battery packs is one of the important problems that needs to be solved.

[0003] Therefore, there is an urgent need for a heavy-duty turntable and a battery pack transfer production line for battery pack transfer production lines to solve the above-mentioned technical problems. Utility Model Content

The rotary drive mechanism is rotatably connected to the rotary support mechanism. The rotary support mechanism is fixedly installed.

[0007] The rotary drive mechanism includes a frame, at least one active caster, and several driven casters. The active and driven casters are symmetrically arranged on the frame, and both the active and driven casters are rotatably mounted on the rotary support mechanism. The roller conveyor mechanism is connected to the frame. The active caster can drive itself to rotate and drive the driven casters to follow, thereby driving the frame and the roller conveyor mechanism to rotate.

[0008] Optionally, the central shaft of the active caster is connected to a drive member, which is used to drive the active caster to rotate.

[0009] Optionally, the frame is provided with multiple mounting brackets, and the mounting brackets are rotatably connected to the driving caster or the driven caster; each mounting bracket is provided with a brush, and the brush is disposed on at least one side of the driving caster or the driven caster along the rotation direction of the frame.

[0010] Optionally, the rotating support mechanism includes a fixed base and a rotating bracket. The fixed base is used for fixed connection with an external fixed structure.

[0011] Optionally, one of the rotary drive mechanism and the rotary support mechanism is provided with a rotary guide member, and the other is provided with a rotary guide shaft. The rotary guide member is rotatably connected to the rotary guide shaft to guide the movement of the rotary drive mechanism.

The position detection component is disposed on the rotary drive mechanism, and the plurality of sensing components are disposed on the rotary support mechanism. The plurality of sensing components are circumferentially spaced apart.

[0015] Optionally, it also includes at least two angled entry and exit guide mechanisms, which are located at the inlet or outlet of the roller conveyor mechanism to guide the entry and exit of the battery pack.

[0016] Another objective of this invention is to provide a battery pack transport production line, including the aforementioned heavy-duty turntable for battery pack transport production line, which can realize the bearing of heavy battery packs and efficient and stable rotational transport, and has high adaptability.

[0018] This invention provides a heavy-duty turntable and a battery pack transport production line for use in battery pack transport production. The turntable employs a rotary drive mechanism mounted beneath a roller conveyor, rotatably connected to a rotary support structure, to achieve rotation of the roller conveyor. Specifically, the rotary drive mechanism consists of at least one driving caster and several driven casters arranged symmetrically in a circle. The connection between the driving and driven casters forms a motion curve, and the rotation of the entire roller conveyor is achieved through the driving of the driving caster. Furthermore, the use of driving and driven casters for load-bearing and driving increases the load-bearing capacity and reduces the size of the rotary drive mechanism, enabling efficient and stable rotational transport of heavy-duty battery packs. The turntable's adaptability can be adjusted by modifying the number of casters, the size of the motion curve formed by the connection between the driving and driven casters, and the length of the roller conveyor, resulting in a simple structure and low cost.

[0039] The following reference Figures 1 to 7 This invention introduces a heavy-duty turntable and a battery pack transport production line for use in battery pack transport production lines.

[0040] Please refer to Figure 1 and Figure 2 This embodiment provides a heavy-duty turntable for a battery pack transport production line, which includes a roller conveyor mechanism 10, a rotary drive mechanism 20, and a rotary support mechanism 30. The roller conveyor mechanism 10 is used to carry and transport battery packs. The output end of the rotary drive mechanism 20 is connected to the roller conveyor mechanism 10 to drive the roller conveyor mechanism 10 to rotate. The rotary drive mechanism 20 is rotatably connected to the rotary support mechanism 30. The rotary support mechanism 30 is fixedly installed. The rotary drive mechanism 20 includes a frame 21, at least one active caster 221, and several driven casters 231. The active caster 221 and the driven casters 231 are symmetrically arranged on the frame 21, and both the active caster 221 and the driven casters 231 are rotatably installed on the rotary support mechanism 30. The roller conveyor mechanism 10 is connected to the frame 21. The active caster 221 can drive itself to rotate and drive the driven casters 231 to follow, so as to drive the frame 21 and the roller conveyor mechanism 10 to rotate.

[0041] The heavy-duty turntable for the battery pack transport production line in this embodiment utilizes a rotary drive mechanism 20 mounted under the roller conveyor mechanism 10. This rotary drive mechanism 20 is rotatably connected to a rotary support structure to achieve rotation of the roller conveyor mechanism 10. Specifically, the rotary drive mechanism 20 is symmetrically arranged circumferentially via at least one driving caster 221 and several driven casters 231. The driving caster 221 and driven casters 231 form a motion curve, and the rotation of the entire roller conveyor mechanism 10 is achieved by driving the driving caster 221. Furthermore, the use of the driving caster 221 and driven casters 231 for load bearing and driving increases its load-bearing capacity and reduces the size of the rotary drive mechanism 20, enabling efficient and stable rotary transport of heavy-duty battery packs. It also allows the heavy-duty turntable used in the battery pack transfer production line to be able to withstand the weight by adjusting the number of casters, the size of the motion curve formed by the connection between the driving caster 221 and the driven caster 231, and the length of the roller conveyor mechanism 10. This improves the adaptability of the heavy-duty turntable and makes it simple in structure and low in cost.

[0042] It should be noted that the heavy-duty turntable for the battery pack transfer production line in this embodiment can support a battery pack loading tray with a total weight not exceeding 3000kg.

[0043] Please refer to Figure 1 In this embodiment, the roller conveyor mechanism 10 includes two parallel and spaced roller conveyors 11, which are mounted on the rotary drive mechanism 20 and are used to carry and transport the battery pack.

[0044] Optionally, the distance between the two roller conveyors 11 is the same as the spacing between roller conveyors 11 on the corresponding production line, so as to realize the docking of the heavy-duty turntable with the transmission production line.

[0045] Specifically, the roller conveyor 11 is provided with multiple load-bearing wheels, which are connected by a drive mechanism. At least one load-bearing wheel is connected to the drive structure of the roller conveyor 11 to realize the conveying and carrying functions of the roller conveyor 11. Of course, in other embodiments, the roller conveyor 11 can also be other specific structures capable of conveying and carrying, which are not specifically limited here.

[0046] Furthermore, the roller conveyor mechanism 10 is also equipped with a stopper and an anti-backward device, which are respectively located on the front and rear sides of the roller conveyor mechanism 10 to limit the battery pack.

[0047] Alternatively, the specific structure and operation of the stopper and anti-backward device can adopt existing structures, and no specific limitations are made here.

[0048] Please refer to Figure 2In this embodiment, the frame 21 has a frame-like structure, which is formed by multiple square steel supports to achieve its structural strength. The roller conveyor mechanism 10 is connected to the frame 21 to enable the frame 21 to support the roller conveyor mechanism 10. Specifically, the frame 21 and each roller conveyor 11 are fixedly connected by bolts, which improves the connection strength between the two.

[0049] Specifically, the frame 21 is provided with multiple mounting brackets, and the mounting brackets are rotatably connected to either a drive caster 221 or a driven caster 231 to enable the installation of the drive caster 221 and the driven caster 231.

[0050] More specifically, the mounting bracket in this embodiment is divided into a first mounting bracket 211 and a second mounting bracket 212. The first mounting bracket 211 is used for mounting the active caster 221, and the second mounting bracket 212 is used for mounting the driven caster 231.

[0051] Optionally, each mounting bracket is provided with a brush 213. Along the rotation direction of the bracket 21, the brush 213 is located on at least one side of the drive caster 221 or the driven caster 231 to clean foreign objects on the movement curve of the drive caster 221 or the driven caster 231 in advance, so as to avoid affecting the rotation of the drive caster 221 or the driven caster 231.

[0052] For example, in this embodiment, the first mounting bracket 211 and the second mounting bracket 212 are each provided with two brushes 213. The two brushes 213 are respectively arranged on both sides of the active caster 221 or the driven caster 231 along the rotation direction of the bracket 21, so that the active caster 221 or the driven caster 231 has brushes 213 to clean foreign objects in advance regardless of whether the active caster 221 or the driven caster 231 rotates forward or backward.

[0053] Furthermore, the driving casters 221 and driven casters 231 of the rotary drive mechanism 20 are connected in sequence to form a motion curve. The driving casters 221 and driven casters 231 rotate around the rotation center of the motion curve to realize the rotational action of the rotary drive mechanism 20.

[0054] Optionally, the number of active casters 221 and the number of driven casters 231 can be set according to actual needs, and no specific limitation is made here. For example, in this embodiment, there is one active caster 221 and three driven casters 231 to support the roller conveyor mechanism 10.

[0055] Specifically, the central shaft of the active caster 221 is connected to a drive component 222, which is used to drive the active caster 221 to rotate, thereby realizing the driving effect of the active caster 221 to rotate.

[0056] Optionally, the drive unit 222 is a forward and reverse motor to realize the forward or reverse rotation of the drive caster 221, thereby realizing the forward and reverse drive of the rotary drive mechanism 20.

[0057] More specifically, the drive caster 221 and the driving component 222 also include a reducer and a transmission structure. The output end of the driving component 222 is connected to the reducer, and the output shaft of the reducer and the drive caster 221 are connected by the transmission structure to drive the drive caster 221. It should be noted that the transmission structure can be a gear drive, belt drive, worm gear drive, etc., as long as it satisfies the requirement of the driving component 222 driving the drive caster 221. No specific limitation is made here.

[0058] For example, the transmission structure in this embodiment includes a first rotating shaft 223 and a first bearing 224. The first rotating shaft 223 is connected to the output shaft of the reducer; the first bearing 224 is disposed on the first rotating shaft 223 and is fixedly connected to the center hole of the drive caster 221 through a flat key, thereby realizing the transmission of the driving force of the drive member 222 to the drive caster 221 to realize the rotation of the drive caster 221.

[0059] Specifically, a second rotating shaft 232 is also included between the driven caster 231 and the second mounting bracket 212. That is, the second mounting bracket 212 is provided with a second rotating shaft 232, and the driven caster 231 is rotatably connected to the second rotating shaft 232 to realize the rotatable connection between the driven caster 231 and the second mounting bracket 212.

[0060] Optionally, a plurality of second bearings 233 are provided between the driven caster 231 and the second rotating shaft 232 to enable the driven caster 231 to rotate smoothly and reduce the friction of its rotation.

[0061] Optionally, both the first bearing 224 and the second bearing 233 can be deep groove ball bearings, which have high load-bearing capacity and meet the requirements of this heavy-duty turntable.

[0062] Please refer to Figure 3 In this embodiment, the rotating support mechanism 30 includes a fixed base 31 and a rotating bracket 32. The fixed base 31 is used for fixed connection with an external fixed structure; the rotating bracket 32 ​​is disposed on the fixed base 31, and the rotating drive mechanism 20 is rotatably connected to the rotating bracket 32. This arrangement allows the external fixed structure of the rotating support mechanism 30 to serve as the source of support force for the rotating drive mechanism. Optionally, the external fixed structure can be a fixed structure such as the ground, which is not specifically limited here.

[0063] Specifically, the fixed base 31 includes a main frame 311 and multiple legs 312. The rotating bracket 32 ​​is fixedly connected to the main frame 311, and the multiple legs 312 are evenly distributed on the main frame 311. The legs 312 are used to be fixedly connected to an external fixed structure.

[0064] More specifically, the outrigger 312 and the external fixing structure are fixedly connected by chemical bolts, which have advantages such as high load-bearing capacity and no expansion stress, to support the battery pack on the heavy-duty turntable.

[0065] Specifically, the shape of the rotating support 32 is the same as the aforementioned motion curve, forming a predetermined motion track to support the corresponding rotating drive mechanism 20. Furthermore, the center of the rotating support 32 coincides with the rotation center, so that the annular structure of the rotating support 32 coincides with the aforementioned motion curve.

[0066] Please refer to Figures 1 to 3 In this embodiment, one of the rotary drive mechanism 20 and the rotary support mechanism 30 is provided with a rotary guide 41, and the other is provided with a rotary guide shaft 42. The rotary guide 41 is rotatably connected to the rotary guide shaft 42 to guide the movement of the rotary drive mechanism 20, thereby improving the stability of the rotary drive mechanism 20 when driving the roller conveyor mechanism 10 to rotate.

[0067] Optionally, the central axis of the rotary guide shaft 42 coincides with the rotation center to ensure the reliability of its rotation and prevent offset problems.

[0068] Specifically, in this embodiment, the rotary guide 41 is disposed on the frame 21 of the rotary drive mechanism 20, and the rotary guide shaft 42 is disposed on the fixed seat 31 of the rotary support mechanism 30, so that the rotary drive mechanism 20 can rotate around the rotary guide shaft 42 to achieve its rotational stability.

[0069] Optionally, the connection between the rotary guide 41 and the frame 21, and the connection between the rotary guide shaft 42 and the fixed base 31, are both fixed by bolts to ensure the stability of the connection. Of course, other connection methods such as welding can also be used in other embodiments, and no specific limitation is made here.

[0070] Specifically, a third bearing 43 is provided between the inner ring of the rotary guide 41 and the outer ring of the rotary guide shaft 42 to achieve rotational engagement between the two and reduce rotational friction between them, thereby improving their service life.

[0071] Optionally, the third bearing 43 is a deep groove ball bearing, which has high load-bearing capacity and meets the requirements of this heavy-duty turntable.

[0072] Please continue to refer to Figures 1 to 3In this embodiment, the heavy-duty turntable for the battery pack transfer production line also includes a sensing mechanism. The sensing mechanism includes a position detection component 51 and multiple sensing components 52. The position detection component 51 is mounted on the rotary drive mechanism 20, specifically on the frame 21. The multiple sensing components 52 are mounted on the rotary support mechanism 30, specifically on the fixed base 31, and are circumferentially spaced. The position detection component 51 rotates with the rotary drive mechanism 20 and can detect the sensing components 52. In use, when the position detection component 51 rotates with the frame 21 and passes the sensing component 52, it can detect the sensing component 52, thereby stopping the operation accordingly, ensuring the accuracy of the heavy-duty turntable's rotation angle. Specifically, an external control device is provided. The control device receives signals from the position detection component 51 and issues stop rotation signals to ensure the accuracy of the heavy-duty turntable when it rotates to a preset position.

[0073] Specifically, in this embodiment, four sensing components 52 are provided and evenly distributed around the circumference of the rotation center, which enables the determination of the position of the heavy-duty turntable at various rotation angles. Of course, in other embodiments, the number of sensing components 52 can be changed according to the actual number of rotation positions, and is not specifically limited here.

[0074] Specifically, the sensing component 52 includes a support bracket 521, a sensing bolt 522, and a sensing block 523. The support bracket 521 is mounted on the rotating support mechanism 30. Both the sensing bolt 522 and the sensing block 523 are mounted on the support bracket 521. The sensing bolt 522 is located at the center of the support bracket 521, and the sensing surface of the sensing block 523 is an arc surface. The sensing bolt 522 is used to ensure the final position of the position detection component 51, and the arc-shaped sensing block 523 is used to allow the position detection component 51 to sense the position in advance and decelerate it, thereby facilitating the heavy-duty turntable to stop at the preset position.

[0075] Specifically, the position detection component 51 includes a deceleration sensor 512 and multiple position sensors 511. The position sensors 511 are configured one-to-one with the sensing bolts 522 to detect the sensing bolts 522. The deceleration sensors 512 are configured one-to-one with the sensing blocks 523 to detect the sensing blocks 523.

[0076] Optionally, both the position sensor 511 and the deceleration sensor 512 described above can be photoelectric sensors to achieve precise sensing and high detection accuracy. Of course, in other embodiments, the position sensor 511 and the deceleration sensor 512 can also be other sensors, which are not specifically limited here.

[0077] Furthermore, the number or position of the sensing bolts 522 in each of the above-mentioned sensing components 52 are different, and the number of position sensors 511 is the same as the number of sensing bolts 522 in the sensing component 52 with the most sensing bolts 522, so as to distinguish the position represented by each sensing component 52, thereby realizing the determination of the rotation angle of the heavy-duty turntable.

[0078] Specifically, in this embodiment, there are three position sensors 511 to realize the number or position arrangement of the sensing bolts 522 in the four sensing components 52, thereby distinguishing each sensing component 52 and the position represented by each sensing component 52.

[0079] Please refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, the heavy-duty turntable for the battery pack transfer production line also includes a limiting mechanism 60. The limiting mechanism 60 includes a limiting block 61 and an abutment block 62. The limiting block 61 is fixedly installed, and the abutment block 62 is installed on the rotary drive mechanism 20, specifically on the frame 21. The abutment block 62 can abut against the limiting block 61 to prevent the rotary drive mechanism 20 from overshooting.

[0080] Specifically, the abutment block 62 is located at any of the four corners of the frame 21. When the roller conveyor mechanism 10 rotates to the position, the abutment block 62 abuts against the limit block 61 at this position to achieve mechanical limit and stop of the turntable.

[0081] Optionally, the contact surface of the abutment block 62 is an arc-shaped surface so that when the abutment block 62 and the limiting block 61 come into contact, it is a line contact, thereby reducing rotational error.

[0082] More specifically, the limiting mechanism 60 also includes a mounting bracket 63, which is fixed to the rotating bracket 32 ​​to improve the convenience of installation and debugging; the limiting block 61 is disposed on the mounting bracket 63 to support and fix the limiting block 61, as well as raise the position of the limiting block 61 so that the limiting block 61 can abut against the abutting block 62.

[0083] Optionally, the mounting bracket 63 is fixedly connected to the rotating bracket 32 ​​by bolts to improve the convenience of installation and debugging. Of course, to facilitate the installation of both, alternatively, one of the mounting bracket 63 and the rotating bracket 32 ​​is provided with a positioning hole, and the other is provided with a positioning pin, which is inserted into the positioning hole to achieve positioning installation of both.

[0084] Furthermore, the position of the limiting block 61 is adjustable, so that after the limiting mechanism 60 is installed, the position of the limiting block 61 can be adjusted, thereby making the position of the limiting block 61 more accurate and also making it easier to improve the adaptability of the limiting mechanism 60.

[0085] Specifically, the limiting block 61 has an oblong hole through which the fixing bolt passes and is fixedly connected to the mounting bracket 63. In use, the limiting block 61 can be slid along the mounting bracket 63 by loosening the fixing bolt, and the fixing bolt can be tightened after it reaches the desired position to fix the limiting block 61.

[0086] More specifically, the limiting mechanism 60 includes a mounting block 64, a limiting adjustment bolt 65, and a tightening bolt 66. The mounting block 64 is fixedly connected to the mounting bracket 63 and spaced apart from the limiting block 61. The tightening bolt 66 is threadedly connected to the mounting block 64, with one end of the tightening bolt 66 passing through the mounting block 64 and abutting against the limiting block 61. One end of the limiting adjustment bolt 65 is limited and positioned on the mounting block 64, while the other end is threadedly connected to the limiting block 61. When the position of the limiting block 61 needs to be adjusted, the tightening bolt 66 is loosened to separate it from the limiting block 61, and the fixing bolt is also loosened, allowing the limiting block 61 to be movable and rotatable. Then, the limiting adjustment bolt 65 is adjusted to move the limiting block 61 to the desired position. Finally, the tightening bolt 66 and the fixing bolt are tightened to fix the limiting block 61, thus completing the position adjustment of the limiting block 61.

[0087] Please refer to Figure 1 and Figure 5 In this embodiment, the heavy-duty turntable for the battery pack transport production line also includes at least two angled entry and exit guide mechanisms 70, which are located at the inlet or outlet of the roller conveyor mechanism 10 to guide the entry and exit of the battery pack.

[0088] Optionally, the number of inlet and outlet guide mechanisms 70 is set according to the number of channels that the heavy-duty turntable needs to transfer, and no specific limitation is made here.

[0089] Specifically, the inlet / outlet guide mechanism 70 includes a fixed bracket 71 and two guide wheels 72. The fixed bracket 71 is fixedly connected to an external fixed structure, which is the ground in this embodiment. The two guide wheels 72 are rotatably disposed above the fixed bracket 71. The two guide wheels 72 are spaced apart and are spaced at the same distance from the inner sides of the two rollers 11 of the roller conveyor mechanism 10. The upper surface of the guide wheels 72 is flush with the upper surface of the support wheel of the roller conveyor mechanism 10, so as to realize the guiding function of the guide wheels 72 on the battery pack or the support tray of the battery pack.

[0090] Optionally, the fixed bracket 71 can directly adopt the fixed structure of the external transport roller conveyor without the need for additional installation, thereby reducing the number of components and lowering the cost of the heavy-duty turntable.

[0091] More specifically, the inlet and outlet guide mechanism 70 also includes two guide seats 73, which are spaced apart above the fixed bracket 71, that is, above the fixed structure of the external conveyor roller, for mounting two guide wheels 72 respectively.

[0092] Furthermore, the inlet and outlet guiding mechanism 70 also includes two guide blocks 74, which are respectively disposed on the outer side of the two guide wheels 72. The guide blocks 74 are provided with guide chamfers to realize the transfer and guidance of the battery pack or the support tray containing the battery pack, so as to avoid the situation where the battery pack or the support tray containing the battery pack tilts in and cannot be docked with the roller conveyor mechanism 10, thereby improving the reliability of the heavy-duty turntable used for the battery pack transfer production line.

[0093] It should be noted that, because the heavy-duty turntable for the battery pack transfer production line adopts a modular design for each structure, the number of connecting channels between the heavy-duty turntable and the production line can be set according to actual needs, thereby adapting to the use of various numbers of channels for transfer and improving the adaptability of the product.

[0094] Please refer to Figures 6 to 7 For example, the heavy-duty turntable for the battery pack transfer production line can be two-channel, three-channel (not shown in the figure), or four-channel. The number and position of each structure in the heavy-duty turntable can be increased or changed adaptively, and no specific limitation is made here.

[0095] Optionally, the heavy-duty turntable for the battery pack transfer production line is also equipped with an equipment housing 80 to protect the production line and operators.

[0096] Specifically, the equipment housing 80 is provided with a channel opening 801 to connect the heavy-duty turntable used for the battery pack transfer production line to an external channel.

[0097] This embodiment also provides a battery pack transport production line, which includes the heavy-duty turntable for battery pack transport production line described in any of the above solutions. This battery pack transport production line has all the above-mentioned beneficial effects, which will not be repeated here.

[0098] The following describes the working process of the heavy-duty turntable for the battery pack transport production line provided in this embodiment:

[0099] First, the battery packs on one section of the transport roller conveyor are transferred to the heavy-duty turntable by the support pallet. The support pallet is aligned by the guide wheels 72 and guide blocks 74 of the in-and-out guide mechanism 70 and transferred to the roller conveyor 11 of the roller conveyor mechanism 10 until it reaches the middle position of the roller conveyor mechanism 10 and is limited by the stopper and anti-backward device. Then, the rotary drive mechanism 20 drives the roller conveyor mechanism 10 to rotate on the rotary support mechanism 30 to the channel to be docked. During the rotation, the deceleration sensor 512 senses the sensing block 523, and the rotary drive mechanism 20 begins to decelerate until the position sensor 511 senses the sensing bolt 522 and stops. Finally, the stopper releases the load, and the support pallet is transferred to another section of the transport roller conveyor by the guide wheels 72 and guide blocks 74 of the in-and-out guide mechanism 70 for operation.

[0100] 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.
