Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically to a battery cell stacking device and stacking equipment. Background Technology

[0002] Vehicle batteries are typically composed of multiple cells. The battery manufacturing process involves stacking multiple cells together and then assembling them to form a battery.

[0003] In the prior art, a battery module stacking and rotating device is described, which includes two stacking fixtures symmetrically arranged on a turntable of an indexing mechanism. Every time the turntable rotates 180°, the two stacking fixtures switch back and forth between the cell loading position and the end plate loading position, thereby improving the production efficiency of the module.

[0004] In existing technologies, battery cells are typically stacked by relying on their own weight to press multiple cells together. This can easily lead to misalignment of different cells during the stacking process, resulting in poor flatness between the cells and thus affecting the assembly quality of the battery. Utility Model Content

[0005] One objective of this invention is to provide a battery cell stacking device to solve the problem of how to improve the flatness between multiple battery cells. A second objective of this invention is to provide a stacking device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] In a first aspect, embodiments of this application provide a battery cell stacking device including a carrying component and a translation component, including a carrying panel for stacking battery cells and a limiting structure disposed on the carrying panel. A positioning component is located on the side of the carrying panel facing the limiting component and is arranged with the limiting component along the length direction of the carrying panel. The positioning component is used to position the battery cells. The translation component is connected to the positioning component and is used to drive the positioning component to move toward or away from the limiting structure so as to cooperate with the limiting structure to stack the battery cells.

[0008] Based on the aforementioned technical means, when stacking multiple battery cells, the cells to be stacked can first be positioned on a positioning component. Then, a translation component moves the positioning component towards a limiting structure to transport the cell to the limiting structure and place it on a support panel. The limiting structure stabilizes the support panel by supporting the cell. The translation component then moves the positioning component again to continue transporting the cells to be stacked. In this way, the cells are stacked on the support panel through the cooperation of the limiting structure, positioning component, and translation component. Because the cells are positioned by the positioning component each time they are transported, the surfaces of the multiple cells are relatively flush after stacking at the limiting structure, ensuring the flatness of the cells and the assembly quality of the battery.

[0009] Furthermore, the positioning components include a clamping structure and a pressing structure. The clamping structure is used to clamp the battery cell from opposite sides of the battery cell, and the pressing structure can be moved to the side of the clamping structure opposite to the support panel to press the battery cell on the clamping structure.

[0010] According to the aforementioned technical means, the positioning component clamps the battery cell along the width direction of the supporting panel using a clamping structure, thereby positioning the battery cell on both sides of the supporting panel in the width direction and ensuring the flatness of the two side surfaces of each battery cell in the width direction of the supporting panel. Furthermore, by pressing the battery cell with a clamping mechanism, the two side surfaces of the battery cell can be positioned from a direction perpendicular to the supporting panel, ensuring the flatness of the two side surfaces of each battery cell in the direction perpendicular to the supporting panel. This better guarantees the flatness of multiple battery cells.

[0011] Furthermore, the clamping structure includes a driving part, a first clamping part, and a second clamping part. The first clamping part and the second clamping part are arranged along the width direction of the bearing panel for clamping the battery cell. The driving part is used to drive the first clamping part and the second clamping part to move toward each other or away from each other.

[0012] According to the above-mentioned technical means, when limiting the battery cell, the battery cell can be placed between the first clamping part and the second clamping part, and then the first clamping part and the second clamping part are driven to move towards each other by the driving part, so that the first clamping part and the second clamping part clamp and limit the battery cell located in the middle of the first clamping part and the second clamping part. The structure of this clamping structure is relatively simple and convenient for clamping and limiting the battery cell.

[0013] Furthermore, the clamping structure includes a first clamping member, a first driving member, and a second driving member. The first driving member is connected to the first clamping member and is used to drive the first clamping member to move in a direction perpendicular to the bearing panel. The second driving member is connected to the first driving member and is used to drive the first driving member to move in the length direction of the bearing panel. The first clamping member is used to clamp the battery cell on the clamping structure.

[0014] According to the above technical means, when it is necessary to place a battery cell onto the clamping assembly, the first driving member can drive the first clamping member to move along the direction opposite to the support panel. Then, the second driving member can drive the first driving member and the clamping member to move away from the clamping assembly along the length direction of the support panel, so that the first clamping member avoids the clamping assembly, thereby facilitating the placement of the battery cell into the clamping assembly. After the battery cell is placed into the clamping assembly, the second driving member can drive the first driving member and the clamping member to move closer to the clamping assembly along the length direction of the support panel, so that the first clamping member moves to the side of the clamping assembly opposite to the support panel. Then, the first driving member can drive the first clamping member to move along the direction towards the support panel, so that the first clamping member presses against the battery cell, thus facilitating the pressing of the battery cell onto the clamping assembly.

[0015] Furthermore, the limiting component includes: a first limiting member, a second clamping member, and a first power member. The first limiting member is connected to the carrier panel and is used to limit the stacked battery cells. The second clamping member is located on the side of the first limiting member facing the limiting component and is spaced apart from the carrier panel. The second clamping member can move towards the carrier panel relative to the first limiting member to clamp the stacked battery cells. The first power member is connected to the second clamping member and is used to drive the second clamping member to move towards the carrier panel.

[0016] According to the above technical means, during the process of stacking battery cells on the carrier panel, the carrier panel can support the battery cells, the first limiting member can limit the battery cells, and on this basis, the first power member drives the second pressing member to move toward the carrier panel, pressing the battery cells onto the carrier panel. This can prevent the battery cells from shaking during the stacking process and causing them to shift, thereby further ensuring the flatness of multiple battery cells.

[0017] Furthermore, the limiting component also includes a second power component, which is connected to the first power component and is used to drive the first power component to move along the length direction of the bearing panel.

[0018] According to the above technical means, the second power member can drive the first power member to move along the length direction of the bearing panel, thereby driving the second pressing member to move along the length direction of the bearing panel. In this way, the position of the second pressing member in the length direction of the bearing panel can be adjusted to adjust the pressing position of the second pressing member, so as to ensure that the second pressing member can better press the battery cell onto the bearing panel.

[0019] Furthermore, the support panel is tilted relative to the vertical direction, and the limiting component is located at the lower end of the support panel.

[0020] According to the above technical means, due to the inclined setting of the support panel, after the battery cell is placed on the support panel, the battery cell can fit more tightly with the support panel under its own weight, thereby improving the support effect of the support panel on the battery cell and further ensuring the flatness of multiple battery cells.

[0021] Secondly, embodiments of this application also provide a stacking device, including a stacking apparatus.

[0022] Furthermore, the stacking device includes a first stacking device and a second stacking device arranged opposite to each other. In the vertical direction, the support panel of the first stacking device and the support panel of the second stacking device are both inclined relative to the vertical direction.

[0023] The upper end of the support panel of the first stacking device is closer to the second stacking device than the lower end of the support panel of the first stacking device, and the upper end of the support panel of the second stacking device is closer to the first stacking device than the lower end of the support panel of the second stacking device.

[0024] According to the above-mentioned technical means, the stacking equipment has a first stacking device and a second stacking device, so that the cells can be stacked on both the first stacking device and the second stacking device. The first stacking device and the second stacking device can realize the rapid stacking of the equipment, increase work efficiency, and save work time.

[0025] Furthermore, the stacking device includes a plurality of first stacking devices and a plurality of second stacking devices, all of which are arranged along a first direction, which is perpendicular to the vertical direction and also perpendicular to the arrangement direction of the first stacking devices and the second stacking devices.

[0026] Based on the above technical means, the stacking equipment has multiple stacking devices. Through multiple first stacking devices and multiple second stacking devices, the equipment can be stacked quickly, increasing work efficiency and saving working time.

[0027] Furthermore, the stacking equipment also includes a support platform and a rotating device. The first stacking device and the second stacking device are both connected to the support platform. The rotating device is connected to the support platform and is used to drive the support platform to rotate on a first plane. The first plane is parallel to the arrangement direction of the first stacking device and the second stacking device.

[0028] According to the above-mentioned technical means, the rotating device can drive the support platform to rotate, thereby driving the stacking device to rotate. In this way, one of the first stacking device and the second stacking device can stack the cells, while the other is used to transfer the stacked cells to the next process, so as to achieve the continuity of cell stacking and the discharge of stacked cells, and improve the efficiency of battery assembly.

[0029] The beneficial effects of this utility model are:

[0030] (1) This utility model can realize the positioning of any side of the battery cell. The battery cell is positioned by the positioning component during the transportation process. Therefore, after multiple battery cells are stacked at the positioning structure, the surfaces of multiple battery cells can be relatively flat, thereby ensuring the flatness of multiple battery cells and ensuring the assembly quality of the battery.

[0031] (2) This utility model uses a positioning component to clamp the battery cell along the width direction of the support panel through a clamping structure. This allows for positioning of the battery cell on both sides of the support panel in the width direction, ensuring the flatness of the two side surfaces of each battery cell in the width direction of the support panel. Furthermore, by pressing the battery cell with a clamping mechanism, the two side surfaces of the battery cell can be positioned from a direction perpendicular to the support panel, ensuring the flatness of the two side surfaces of each battery cell in the direction perpendicular to the support panel. This better ensures the flatness of multiple battery cells.

[0032] (3) In this utility model, the first clamping part and the second clamping part are driven by the driving part to move toward each other, so that the first clamping part and the second clamping part clamp and limit the battery cell located in the middle of the first clamping part and the second clamping part. The structure of this clamping structure is relatively simple and convenient for clamping and limiting the battery cell.

[0033] (4) In this utility model, the first driving member drives the first pressing member to move along the direction opposite to the bearing panel, and then the second driving member drives the first driving member and the pressing member to move away from the clamping assembly along the length direction of the bearing panel, so that the first pressing member avoids the clamping assembly, thereby facilitating the placement of the battery cell into the clamping assembly. After the battery cell is placed into the clamping assembly, the second driving member can drive the first driving member and the pressing member to move closer to the clamping assembly along the length direction of the bearing panel, so that the first pressing member moves to the side of the clamping assembly opposite to the bearing panel, and then the first driving member drives the first pressing member to move along the direction toward the bearing panel, so that the first pressing member presses against the battery cell, thus facilitating the pressing of the battery cell onto the clamping assembly.

[0034] (5) The present invention drives the second pressing member to move toward the bearing panel by the first power member, pressing the battery cell onto the bearing panel, which can prevent the battery cell from shaking during the stacking process and causing the battery cell to shift, so as to further ensure the flatness of multiple battery cells.

[0035] (6) The present invention can drive the first power member to move along the length direction of the bearing panel through the second power member, thereby driving the second pressing member to move along the length direction of the bearing panel. In this way, the position of the second pressing member in the length direction of the bearing panel can be adjusted to adjust the pressing position of the second pressing member, so as to ensure that the second pressing member can press the battery cell better on the bearing panel.

[0036] (7) Because the bearing panel is tilted, after the battery cell is placed on the bearing panel, the battery cell can fit more tightly with the bearing panel under its own weight, thereby improving the bearing effect of the bearing panel on the battery cell and further ensuring the flatness of multiple battery cells.

[0037] (8) This utility model uses a first stacking device and a second stacking device of a stacking equipment, so that the cells can be stacked on both the first stacking device and the second stacking device. The first stacking device and the second stacking device can realize the rapid stacking of the equipment, increase work efficiency and save work time.

[0038] (9) This utility model achieves rapid stacking of equipment by using multiple stacking devices of stacking equipment, multiple first stacking devices and multiple second stacking devices, thereby increasing work efficiency and saving work time.

[0039] (10) This utility model drives the support platform to rotate through the rotating device, thereby driving the stacking device to rotate. In this way, one of the first stacking device and the second stacking device can stack the cells, while the other is used to transfer the stacked cells to the next process, so as to achieve the continuity of cell stacking and the discharge of the stacked cells and improve the efficiency of battery assembly.

[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0066] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0067] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0068] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines, the terms "connected" and "linked" as used in this application have the meaning of establishing electrical connection. The specific meaning needs to be understood in conjunction with the context.

[0069] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0070] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0071] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1A battery cell stacking device provided in this application includes a support component 1, a positioning component 2, and a translation component 5. The support component 1 includes a support panel 11 for stacking battery cells and a limiting component 3 disposed on the support panel 11. The positioning component 2 is located on the side of the support panel 11 facing the limiting component 3 and is arranged along the length direction of the support panel 11 with the limiting component 3. The positioning component 2 is used to position the battery cells 4. The translation component 5 is connected to the positioning component 2 and is used to move the positioning component 2 toward or away from the limiting component 3 to cooperate with the limiting component 3 to stack the battery cells 4. The battery cell stacking device also includes a support structure 51, which is used to support the support panel 11, the limiting component 3, and the translation component 5. The support structure 51 can be a plate-like structure or other structure capable of supporting the support panel 11, the limiting component 3, and the translation component 5.

[0072] In this way, when stacking multiple battery cells 4, the cells to be stacked can first be positioned on the positioning component 2. Then, the translation component 5 moves the positioning component 2 towards the limiting component 3 to transport the battery cell 4 to the limiting component 3 and place it on the support panel 11. The limiting component 3 limits the support panel 11 to stably support the battery cell 4. Then, the translation component 5 moves the positioning component 2 again to continue transporting the battery cells to be stacked. In this way, the battery cells 4 are stacked on the support panel 11 through the cooperation of the limiting component 3, the positioning component 2, and the translation component 5. Since the battery cell 4 is positioned by the positioning component 2 each time during the transport process, after multiple battery cells 4 are stacked at the limiting component 3, the surfaces of the multiple battery cells 4 can be kept relatively flat, thereby ensuring the flatness of the multiple battery cells 4 and ensuring the assembly quality of the battery.

[0073] In some embodiments, please refer to Figure 5 The positioning component 2 includes a clamping structure 21 and a pressing structure 22. The clamping structure 21 is used to clamp the battery cell 4 from opposite sides of the battery cell 4. The pressing structure 22 can move to the side of the clamping structure 21 that is away from the bearing panel 11 to press the battery cell 4 on the clamping structure 21.

[0074] In this way, the positioning component 2 clamps the battery cell 4 along the width direction of the support panel 11 through the clamping structure 21, which can position the battery cell 4 on both sides of the support panel 11 in the width direction, ensuring the flatness of the two side surfaces of each battery cell in the width direction of the support panel 11. Furthermore, by pressing the battery cell through the pressing mechanism 22, the two sides of the battery cell 4 can be positioned from the direction perpendicular to the support panel 11, ensuring the flatness of the two side surfaces of each battery cell 4 in the direction perpendicular to the support panel 11. This can better ensure the flatness of multiple battery cells 4.

[0075] In some other embodiments, the positioning component 2 may only include the clamping structure 21 to position each battery cell 4 on both sides in the width direction of the support plate 11. In this case, a structure for positioning the battery cell 4 on both sides in the direction perpendicular to the support plate 11 can be provided on the limiting component 3. This can improve the flatness of the multiple battery cells 4.

[0076] In some embodiments, please refer to Figure 6 The clamping structure 21 includes a driving part 211, a first clamping part 212 and a second clamping part 213. The first clamping part 212 and the second clamping part 213 are arranged along the width direction of the bearing panel 11 and are used to clamp the battery cell 4. The driving part 211 is used to drive the first clamping part 212 and the second clamping part 213 to move toward each other or away from each other.

[0077] In this way, when limiting the position of the battery cell 4, the battery cell 4 can be placed between the first clamping part 212 and the second clamping part 213. Then, the driving part 211 drives the first clamping part 212 and the second clamping part 213 to move towards each other, so that the first clamping part 212 and the second clamping part 213 clamp and limit the position of the battery cell 4 located in the middle of the first clamping part 212 and the second clamping part 213. The structure of this clamping structure is relatively simple and convenient for clamping and limiting the position of the battery cell 4.

[0078] In some examples, the first clamping part 212 and the second clamping part 213 can be a plate-like structure, a block-like structure, etc.

[0079] In some examples, the drive unit 211 can be a cylinder, such as a two-way cylinder. In other examples, the drive unit 211 can also be an electric actuator, etc. For example, the drive unit 211 can be two electric actuators, one of which pushes the first clamping part 212 to move, and the other electric actuator pushes the second clamping part 213 to move. This application does not specifically limit this.

[0080] In some examples, one or more battery cells 4 can be placed between the first clamping part 212 and the second clamping part 213.

[0081] In some other embodiments, the clamping structure 21 may further include a first clamping portion 212, a second clamping portion 213, and a support plate. The first clamping portion 212 and the second clamping portion 213 can be slidably connected to the support plate in a direction close to or far from each other. A first spring is provided between the first clamping portion 212 and the support plate, and the first spring applies a spring force to the first clamping portion 212 toward the second clamping portion 213. A second spring is provided between the second clamping portion 213 and the support plate, and the second spring applies a spring force to the second clamping portion 213 toward the first clamping portion 212. After the battery cell 4 is placed between the first clamping portion 212 and the second clamping portion 213, the first and second springs can clamp and fix the battery cell 4.

[0082] In some embodiments, please refer to Figure 7 The clamping structure 22 includes a first clamping member 221, a first driving member 222, and a second driving member 223. The first driving member 222 is connected to the first clamping member 221 and is used to drive the first clamping member 221 to move in a direction perpendicular to the bearing panel 11. The second driving member 223 is connected to the first driving member 222 and is used to drive the first driving member 222 to move in the length direction of the bearing panel 11. The first clamping member 221 is used to clamp the battery cell 4 on the clamping structure 22.

[0083] In this way, when it is necessary to place the battery cell 4 onto the clamping assembly, the first driving member 222 can drive the first clamping member 221 to move in the direction away from the support panel 11. Then, the second driving member 223 can drive the first driving member 222 and the clamping member to move away from the clamping assembly along the length direction of the support panel 11, so that the first clamping member 221 avoids the clamping assembly, thereby facilitating the placement of the battery cell 4 into the clamping assembly. After the battery cell 4 is placed into the clamping assembly, the second driving member 223 can drive the first driving member 222 and the clamping member to move closer to the clamping assembly along the length direction of the support panel 11, so that the first clamping member 221 moves to the side of the clamping assembly away from the support panel 11. Then, the first driving member 222 can drive the first clamping member 221 to move in the direction towards the support panel 11, so that the first clamping member 221 presses against the battery cell 4, thus facilitating the clamping of the battery cell 4 onto the clamping assembly.

[0084] In some examples, the first clamping member 221 can be a plate-like structure, a block-like structure, etc. The first driving member 222 and the second driving member 223 can be a cylinder, an electric push rod, etc.

[0085] In other embodiments, the clamping structure 22 may also be other structures capable of clamping the battery cell 4 onto the clamping assembly, such as rotating to avoid the clamping assembly and clamping the battery cell 4 onto the clamping assembly.

[0086] In some embodiments, please refer to Figure 8 The limiting component 3 includes a first limiting member 31, a second clamping member 32, and a first power member 33. The first limiting member 31 is connected to the support panel 11 and is used to limit the stacked battery cells 4. For example, the first limiting member 31 can be a plate-like structure, a block-like structure, an L-shaped plate-like structure, or other regular or irregular structures, etc., and this application does not make specific limitations in this regard. When the battery cell 4 is moved to the limiting component 3 by the positioning component 2 and the translation component 5, the battery cell 4 closest to the limiting component 3 among the multiple battery cells 4 will come into contact with the first limiting member 31 and be blocked and limited by the first limiting member 31 to ensure the position of the multiple battery cells 4 on the support panel 11.

[0087] The second clamping member 32 is located on the side of the first limiting member 31 facing the limiting component 3 and is spaced apart from the carrier panel 11. The second clamping member 32 can move toward the carrier panel 11 relative to the first limiting member 31 to clamp the stacked battery cells 4. The first power member 33 is connected to the second clamping member 32 and is used to drive the second clamping member 32 to move toward the carrier panel 11.

[0088] In this way, during the process of stacking the battery cells 4 on the support panel 11, the support panel 11 can support the battery cells 4, and the first limiting member 31 can limit the battery cells 4. On this basis, the first power member 33 drives the second pressing member 32 to move toward the support panel 11, pressing the battery cells 4 onto the support panel 11. This can prevent the battery cells 4 from shaking during the stacking process and causing the battery cells 4 to shift, thereby further ensuring the flatness of the multiple battery cells 4.

[0089] In some examples, the second clamping element can be a plate-like structure, a block-like structure, etc.

[0090] In some embodiments, the first power component 33 may be a cylinder, a hydraulic cylinder, or a linear motor, etc.

[0091] In some embodiments, please refer to Figure 8 and Figure 9 The limiting component 3 also includes a second power component 34, which is connected to the first power component 33 and is used to drive the first power component 33 to move along the length direction of the bearing panel 11.

[0092] In this way, the second power member 34 can drive the first power member 33 to move along the length direction of the support panel 11, thereby driving the second pressing member 32 to move along the length direction of the support panel 11. This allows the position of the second pressing member 32 in the length direction of the support panel 11 to be adjusted, thereby adjusting the pressing position of the second pressing member 32 and ensuring that the second pressing member 32 can better press the battery cell 4 onto the support panel 11.

[0093] In some other embodiments, the second power component 34 can be an electric telescopic rod, a cylinder, an electric push rod, etc.

[0094] In some embodiments, please refer to Figure 10 The support panel 11 is inclined relative to the vertical direction, and the limiting component 3 is located at the lower end of the support panel 11.

[0095] In this way, because the support panel 11 is tilted, after the battery cell 4 is placed on the support panel, the battery cell 4 can fit more tightly with the support panel 11 under its own weight, thereby improving the support effect of the support panel 11 on the battery cell 4 and further ensuring the flatness of multiple battery cells 4.

[0096] In some embodiments, please refer to Figure 11 This application also provides a stacking device, which includes a stacking apparatus.

[0097] In some embodiments, please refer to Figure 10 The stacking device includes a first stacking device 7 and a second stacking device 8 arranged opposite each other.

Multiple first stacking devices 7 are connected to the first fixing plate 92, and multiple second stacking devices 8 are connected to the second fixing plate 93. In some examples, the support platform 9 also includes a support frame 94, which is connected to the support base plate 91 and located between the first fixing plate 92 and the second fixing plate 93. Both the first fixing plate 92 and the second fixing plate 93 are connected to the support frame 94. The support frame 94 supports the first fixing plate 92 and the second fixing plate 93, thereby improving the support effect on the first stacking device 7 and the second stacking device 8.

[0102] The rotating device 6 is connected to the support platform 9 and is used to drive the support platform 9 to rotate on a first plane, which is parallel to the arrangement direction of the first stacking device 7 and the second stacking device 8.

[0103] In this way, the rotating device 6 can drive the support platform 9 to rotate, thereby driving the stacking device to rotate. Thus, one of the first stacking device 7 and the second stacking device 8 can stack the battery cells 4, while the other is used to transfer the stacked battery cells 4 to the next process, so as to achieve the continuity of battery cell 4 stacking and the discharge of the stacked battery cells 4, and improve the efficiency of battery assembly.

[0104] In some examples, the stacked cell 4 is transferred to the next process, and the cell 4 is placed on the clamping assembly via a mechanical axis.

[0105] In some embodiments, please refer to Figure 12 , Figure 13 and Figure 14 The rotating device 6 may include a base 10, a servo motor 61, and a cam divider 62.
