Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a steel-cased battery cell flipping mechanism. Background Technology

[0002] As the core component of batteries, battery cells play a crucial role in modern electronic devices. From smartphones and laptops to electric vehicles and energy storage systems, the quality of battery cells directly affects the performance and safety of the final product. With technological advancements, the requirements for battery cell energy density, lifespan, and charging speed are increasing, which has spurred continuous progress and optimization in battery cell manufacturing processes.

[0003] Steel-cased battery cells are battery cells that use steel as their outer casing material. Due to their higher mechanical strength and better impact resistance, they are widely used in many fields. The manufacturing of steel-cased battery cells involves multiple complex processes, and the steel-cased battery cells are usually handled between different processes. To accommodate the processing requirements of subsequent processes, it is sometimes necessary to flip the steel-cased battery cells from one direction to another during handling to ensure that they enter the next process in the correct orientation.

[0004] In existing steel-cased battery cell flipping mechanisms, to prevent the steel-cased battery cells from falling off during the flipping process, magnets are typically used to hold the cells in place. Then, the grippers in the next process overcome the magnetic attraction to remove the battery cell for further processing. However, if the magnet's magnetism is too weak, the resulting attraction is insufficient, posing a risk of the battery cell falling during handling and reducing the reliability of the process. Conversely, if a strong magnet is used, the grippers in the next process will need to apply greater clamping force to remove the battery cell, increasing the risk of damage to its appearance and ultimately affecting the production quality. Utility Model Content

[0005] This utility model provides a steel-shell battery cell flipping mechanism for flipping battery cells during handling, which can improve the reliability of cell flipping and enhance the production quality of the battery cells. The specific solution is as follows:

[0006] A steel-shell battery cell flipping mechanism for flipping steel-shell battery cells includes a support frame and a battery cell fixture, a magnetic attraction mechanism, a rotation mechanism and a demagnetizing mechanism disposed on the support frame.

[0007] The battery cell fixture is provided with at least one battery cell slot for placing the steel-cased battery cell;

[0008] The magnetic attraction mechanism is mounted on the battery cell fixture and can fix the steel-shell battery cell onto the battery cell slot.

[0009] The rotating mechanism can drive the battery cell fixture to rotate along the axis;

[0010] The demagnetizing mechanism can eliminate or weaken the magnetic attraction force of the magnetic attraction mechanism on the steel-cased battery cell.

[0011] Furthermore, the magnetic attraction mechanism is a controllable magnetic force device, and the demagnetizing mechanism can adjust the magnetic force of the magnetic attraction mechanism.

[0012] Furthermore, the magnetic attraction mechanism is a fixed magnetic device, and the demagnetizing mechanism can drive the magnetic attraction mechanism to move closer to or away from the battery cell fixture.

[0013] Furthermore, the demagnetizing mechanism includes a demagnetizing cylinder and a linear axis; the demagnetizing cylinder can drive the magnetic attraction mechanism to move along the linear axis, moving closer to or away from the battery cell fixture.

[0014] Furthermore, the number of battery cell slots on the battery cell fixture is two or more; the magnetic attraction mechanism is provided with magnetic devices that are the same number as the number of battery cell slots, the magnetic devices are fixedly connected to each other by connecting rods, and the positions of the magnetic devices correspond one-to-one with the positions of the battery cell slots.

[0015] Furthermore, the rotating mechanism can drive the battery cell fixture to reciprocate 90° along the axis.

[0016] Furthermore, the rotation angle of the battery cell fixture is adjustable.

[0017] Furthermore, the cell slot includes a vertically arranged support surface and a wrapping surface; the support surface is adapted to the end face of the steel-cased cell, and can fit against and support the end face of the steel-cased cell; the wrapping surface is adapted to the side face of the steel-cased cell, and can partially wrap the side face of the steel-cased cell; the magnetic attraction mechanism is disposed at the wrapping surface, and can attract the side face of the steel-cased cell, fixing the steel-cased cell on the cell slot.

[0018] Furthermore, a groove is provided in the middle of the wrapping surface, and the length direction of the groove is parallel to the supporting surface.

[0019] Furthermore, the height of the wrapping surface is less than the height of the steel-cased battery cell, such that when the steel-cased battery cell is placed in the battery cell slot and the lower end face of the steel-cased battery cell contacts the supporting surface, the upper end face of the steel-cased battery cell protrudes above the wrapping surface.

[0020] The steel-shell battery cell flipping mechanism provided by this utility model, through the interaction between the battery cell fixture, magnetic attraction mechanism, rotation mechanism and demagnetization mechanism, can not only realize the flipping of the steel-shell battery cell and meet the connection between different processes, but also improve the reliability of the steel-shell battery cell flipping mechanism and improve the production quality of the steel-shell battery cell.

[0021] In some embodiments, the magnetic attraction mechanism is a controllable magnetic device, and the demagnetizing mechanism can adjust the magnetic force of the magnetic attraction mechanism, which can quickly and accurately adjust the magnetic attraction force of the magnetic attraction mechanism on the steel-cased battery cell, making it suitable for application scenarios that require fast response and precise control.

[0022] In some embodiments, the magnetic attraction mechanism is a fixed magnetic device, and the demagnetizing mechanism can drive the magnetic attraction mechanism to move closer to or away from the battery cell fixture. With a simple and low-cost structure, the magnetic attraction force of the magnetic attraction mechanism on the steel-cased battery cell can be eliminated or weakened, which can reduce costs and facilitate maintenance.

[0023] In some embodiments, when the number of cell slots on the cell fixture is two or more, a magnetic device is provided in the magnetic attraction mechanism that corresponds to the number and position of the cell slots. This can make the magnetic attraction force on each cell slot evenly distributed, thereby ensuring that the steel-shell cell in each cell slot can be stably fixed, and improving the reliability of the steel-shell cell flipping mechanism.

[0024] In some embodiments, the rotating mechanism can drive the cell fixture to reciprocate 90° along the axis, which can meet the basic cell handling and flipping requirements in the production process of the steel-cased cell, and has a simple structure, high reliability, and is easy to maintain.

[0025] In some embodiments, the rotation angle of the battery cell fixture is adjustable, which can meet the needs of more different application scenarios, making it more adaptable and versatile.

[0026] In some embodiments, the cell slot includes a vertically arranged support surface and a wrapping surface, which can support the steel-cased cell while partially wrapping the side of the steel-cased cell. The magnetic attraction mechanism is located at the wrapping surface, which can attract the side of the steel-cased cell and fix the steel-cased cell on the cell slot. This allows the steel-cased cell to be placed more stably in the cell slot and facilitates the placement and removal of the steel-cased cell, thereby improving the reliability and convenience of the steel-cased cell flipping mechanism.

[0027] In some embodiments, a groove is provided in the middle of the wrapping surface, which allows the grippers to better clamp the sides of the steel-cased battery cell when the steel-cased battery cell is picked up and placed by the grippers, thereby improving reliability.

[0028] In some embodiments, the height of the wrapping surface is less than the height of the steel-cased battery cell, causing the upper end face of the steel-cased battery cell to protrude above the wrapping surface. This allows the grippers to clamp the end of the steel-cased battery cell, making it more adaptable to the material handling needs of more diverse production scenarios. Attached Figure Description

[0037] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. For ease of explanation, the terms "front," "rear," "positive," "negative," "left," "right," "top," "bottom," "upper," "lower," "inner," "outer," and "inner" in this utility model indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component 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 or limitations on the actual orientation of the product or device during production, use, sales, etc. In addition, in the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," and "composition" 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 direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0038] This utility model provides a steel-cased battery cell flipping mechanism, which can be used for flipping the battery cell 1 during the handling process. In this embodiment, the structure of the steel-cased battery cell 1 is as follows: Figure 1 As shown, the whole is cylindrical. The flat portions at both ends of the steel-cased battery cell 1 are the end faces 11 of the steel-cased battery cell 1, and the cylindrical outer surface of the main body of the steel-cased battery cell 1 (i.e., the side surface extending from one end of the steel-cased battery cell 1 to the other end) is the side surface 12 of the steel-cased battery cell 1. The end faces 11 are perpendicular to the side surfaces 12. Of course, in addition to the steel-cased battery cell 1 with the above structure, the flipping of other similar steel-cased battery cells 1 can also be applied, and there is no limitation here.

[0039] like Figure 2 , Figure 3 The diagram shown is a structural schematic of the steel-cased battery cell flipping mechanism. Figure 4 , Figure 5 The diagram shown illustrates the usage state of the steel-shell battery cell flipping mechanism. Specifically, the steel-shell battery cell flipping mechanism includes a support frame 2 and a battery cell fixture 3, a magnetic attraction mechanism 4, a rotation mechanism 5, and a demagnetizing mechanism 6 mounted on the support frame 2, wherein:

[0040] The cell fixture 3 is movably mounted on the support frame 2. Under the drive of external force, it can rotate along the axis of the cell fixture 3. The cell fixture 3 is provided with at least one cell slot 31 for placing the steel-shell cell 1. In this embodiment, the number of cell slots 31 is 4. In actual application, they can be increased or decreased as needed, and there is no limitation here.

[0041] The magnetic attraction mechanism 4 is disposed on the battery cell fixture 3, which can fix the steel-shell battery cell 1 on the battery cell slot 31. Specifically, the magnetic attraction mechanism 4 can be an ordinary magnet or an electromagnet or other magnetic attraction component. The magnetic attraction mechanism 4 can fix the steel-shell battery cell 1 on the battery cell slot 31 by attracting the end face 11 of the steel-shell battery cell 1, or it can fix the steel-shell battery cell 1 on the side face 12 of the steel-shell battery cell 1. There is no limitation here.

[0042] The rotating mechanism 5 can be used to drive the cell fixture 3 to rotate along the axis of the cell fixture 3, thereby realizing the flipping of the steel-cased cell 1.

[0043] The demagnetizing mechanism 6 can be used to eliminate or weaken the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-shell battery cell 1. That is, it can completely eliminate the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-shell battery cell 1, making the magnetic attraction force zero, or it can weaken the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-shell battery cell 1, so that the gripper of the next process can easily remove the steel-shell battery cell 1. The elimination or weakening of the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-shell battery cell 1 can be achieved by eliminating or weakening the magnetic attraction force of the magnetic attraction mechanism 4 itself, or by increasing the physical distance between the magnetic attraction mechanism 4 and the steel-shell battery cell 1. There is no limitation here.

[0044] In use, firstly, after the previous process is completed, the gripper from the previous process moves the steel-shell battery cell 1 into this mechanism and places it in the battery cell slot 31 of the battery cell fixture 3; then, the magnetic attraction mechanism 4 attracts the steel-shell battery cell 1 and fixes it on the battery cell slot 31; subsequently, the rotating mechanism 5 drives the battery cell fixture 3 to rotate along its axis, thereby flipping the steel-shell battery cell 1; after flipping, the gripper from the next process moves into this mechanism and clamps the steel-shell battery cell 1. At this time, the demagnetizing mechanism 6 comes into play, eliminating or weakening the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-shell battery cell 1, and then the gripper from the next process can easily remove the steel-shell battery cell 1; of course, the gripper from the previous process and the gripper from the next process can also be replaced with other battery cell moving mechanisms, which are not limited here.

[0045] The steel-shell battery cell flipping mechanism with the above structure, through the interaction between the battery cell fixture 3, the magnetic attraction mechanism 4, the rotation mechanism 5 and the demagnetization mechanism 6, can not only realize the flipping of the steel-shell battery cell 1 and meet the connection between different processes, but also improve the reliability of the steel-shell battery cell flipping mechanism and improve the production quality of the steel-shell battery cell 1.

[0046] In some embodiments, the magnetic attraction mechanism 4 is a controllable magnetic force device, and the demagnetizing mechanism 6 can adjust the magnetic force of the magnetic attraction mechanism 4; for example, when the magnetic attraction mechanism 4 is an electromagnet, the demagnetizing mechanism 6 can effectively adjust the magnetic attraction force of the magnetic attraction mechanism 4 itself by adjusting the current or even completely cutting off the current, thereby effectively adjusting the magnetic attraction force of the magnetic attraction mechanism 4 on the steel shell battery cell 1.

[0047] The steel-cased battery cell flipping mechanism with the above structure has a controllable magnetic force device in the magnetic attraction mechanism 4 and a demagnetizing mechanism 6 that can adjust the magnetic force of the magnetic attraction mechanism 4. This allows for quick and precise adjustment of the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-cased battery cell 1, making it very suitable for application scenarios that require fast response and precise control.

[0048] In some embodiments, the magnetic attraction mechanism 4 is a fixed magnetic device, such as an ordinary magnet with a fixed magnetic force. The demagnetizing mechanism 6 can drive the magnetic attraction mechanism 4 to move closer to or away from the battery cell fixture 3, thereby increasing the physical distance between the magnetic attraction mechanism 4 and the steel-cased battery cell 1, which can eliminate or weaken the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-cased battery cell 1.

[0049] The steel-shell battery cell flipping mechanism with the above structure has a magnetic attraction mechanism 4 that is a fixed magnetic force device. The demagnetizing mechanism 6 can drive the magnetic attraction mechanism 4 to move closer to or away from the battery cell fixture 3. The magnetic attraction force of the magnetic attraction mechanism 4 on the steel-shell battery cell 1 can be eliminated or weakened through a simple and low-cost structure, which can reduce costs and facilitate maintenance.

[0050] In some embodiments, such as Figure 6 As shown, the demagnetizing mechanism 6 includes a demagnetizing cylinder 61 and a linear axis 62; the demagnetizing cylinder 61 can drive the magnetic attraction mechanism 4 to move along the linear axis 62, moving closer to or away from the battery cell fixture 3.

[0051] The steel-shell battery cell flipping mechanism with the above structure uses the demagnetizing cylinder 61 to drive the magnetic attraction mechanism 4 to move on the linear axis 62, away from the battery cell fixture 3, which can eliminate or weaken the magnetic attraction force of the magnetic attraction mechanism 4 on the steel-shell battery cell 1. The structure is simple, easy to maintain, and low in cost.

[0052] In some embodiments, the number of cell slots 31 on the cell fixture 3 is two or more, and the magnetic attraction mechanism 4 is provided with a magnetic device 41 that matches the number of cell slots 31 (e.g., in this embodiment, such as...). Figure 6As shown, there are four battery cell slots 31, and therefore four magnetic devices 41 on the magnetic attraction mechanism 4. The magnetic devices 41 are fixedly connected by connecting rods 42, and the positions of the magnetic devices 41 correspond one-to-one with the positions of the battery cell slots 31.

[0053] When the number of cell slots 31 on the cell fixture 3 is two or more, a magnetic device 41 corresponding to the number and position of the cell slots 31 is provided in the magnetic attraction mechanism 4. This allows the magnetic attraction force on each cell slot 31 to be evenly distributed, thereby ensuring that the steel-shell cell 1 in each cell slot 31 can be stably fixed, which can improve the reliability of the steel-shell cell flipping mechanism.

[0054] In some embodiments, the rotating mechanism 5 can drive the battery cell fixture 3 to reciprocate 90° along the axis; for example, in this embodiment, such as Figure 4 , Figure 5 As shown, the rotating mechanism 5 drives the cell fixture 3 to rotate 90° counterclockwise along the axis to flip the steel-cased cell 1, and then drives the cell fixture 3 to rotate 90° clockwise along the axis to complete the reset. Of course, the rotating mechanism 5 can also drive the cell fixture 3 to rotate 90° clockwise along the axis to flip the steel-cased cell 1, and then drive the cell fixture 3 to rotate 90° counterclockwise along the axis to complete the reset. The specific method can be determined according to the placement position of the steel-cased cell 1 in the cell fixture 3 and the actual flipping requirements, and is not limited here.

[0055] The steel-shell battery cell flipping mechanism with the above structure can drive the battery cell fixture 3 to reciprocate 90° along the axis, which can meet the basic battery cell handling and flipping requirements in the production process of the steel-shell battery cell 1. It has a simple structure, high reliability, and is easy to maintain.

[0056] In some embodiments, the rotation angle of the battery cell fixture 3 can be adjusted, for example, by rotating 180°, and the specific angle can be determined according to actual production needs, without limitation here.

[0057] The steel-shell battery cell flipping mechanism with the above structure has an adjustable rotation angle for the battery cell fixture 3, which can meet the needs of more different application scenarios, making it more adaptable and versatile.

[0058] In some embodiments, such as Figure 7As shown, the cell slot 31 includes a vertically arranged support surface 311 and a wrapping surface 312; the support surface 311 is adapted to the end face 11 of the steel-cased cell 1, and can fit against the end face 11 of the steel-cased cell 1 to support the steel-cased cell 1; the wrapping surface 312 is adapted to the side face 12 of the steel-cased cell 1, and can partially wrap the side face 12 of the steel-cased cell 1; the magnetic attraction mechanism 4 is disposed at the wrapping surface 312, and can attract the side face 12 of the steel-cased cell 1 to fix the steel-cased cell 1 on the cell slot 31.

[0059] The steel-shell battery cell flipping mechanism with the above structure includes a vertically arranged support surface 311 and a wrapping surface 312 in the cell slot 31. This allows for the support of the steel-shell battery cell 1 while partially wrapping the side 12 of the steel-shell battery cell 1. The magnetic attraction mechanism 4 is located at the wrapping surface 312, which can attract and hold the side 12 of the steel-shell battery cell 1, fixing the steel-shell battery cell 1 to the cell slot 31. This allows the steel-shell battery cell 1 to be placed more stably in the cell slot 31 and facilitates its placement and removal, thereby improving the reliability and convenience of the steel-shell battery cell flipping mechanism.

[0060] In some embodiments, continue as follows Figure 7 As shown, a groove 313 is provided in the middle of the wrapping surface 312, and the length direction of the groove 313 is parallel to the support surface 311.

[0061] The steel-shell battery cell flipping mechanism with the above structure has a groove 313 in the middle of the wrapping surface 312. When the steel-shell battery cell 1 is picked up and put down by the gripper, the gripper can better clamp the side 12 of the steel-shell battery cell 1, thereby improving reliability.

[0062] In some embodiments, the height of the wrapping surface 312 is less than the height of the steel-cased battery cell 1, such that when the steel-cased battery cell 1 is placed in the battery cell slot 31 and the lower end face 11 of the steel-cased battery cell 1 contacts the support surface 311, the upper end face 11 of the steel-cased battery cell 1 protrudes above the wrapping surface 312.

[0063] The steel-shell battery cell flipping mechanism with the above structure has a height of the wrapping surface 312 that is less than the height of the steel-shell battery cell 1, so that the upper end face 11 of the steel-shell battery cell 1 protrudes above the wrapping surface 312, thereby allowing the grippers to clamp the end of the steel-shell battery cell 1. This can adapt to the material handling needs of more different production scenarios and has higher adaptability.

[0064] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. All equivalent changes made in accordance with the shape, structure and principle of the present utility model should be covered within the protection scope of the present utility model.
