Description

Technical Field

[0001] This invention relates to the field of battery cell processing technology, and in particular to a battery cell transmission device, a battery cell, a battery pack, and an energy storage device. Background Technology

[0002] In the manufacturing process of cylindrical battery cells, when a process is completed, the battery cell usually needs to be moved from one conveyor belt to another conveyor belt with intersecting transmission directions for transfer. This separates the different stages of the process and allows for processing or handling in different directions. However, during the transfer process, there needs to be a height difference between the conveyor belts. When the battery cell falls, its position will be offset. Or, if there are too many channels for transporting battery cells to another conveyor belt, it will often lead to the problem of battery cells colliding with each other and damaging the battery cells.

[0003] Therefore, a new cell transfer device is needed to prevent cells from colliding with each other during transfer. Summary of the Invention

[0004] The purpose of this application is to provide a battery cell transmission device to solve the problem of battery cells colliding with each other during cell transfer.

[0005] To achieve the above objectives, this application embodiment includes a cell transfer device, employing the following technical solution: a base, on which a material transfer device is mounted; the material transfer device includes: a support frame, mounted on the base; a first support plate, mounted on the support frame and equipped with a moving shaft, the moving shaft being connected to a first drive cylinder; a movable seat, mounted on the moving shaft; a second support plate, mounted on the movable seat; a second drive cylinder, mounted on the second support plate and connected to a balance plate; and an adsorption element, mounted at both ends of the balance plate, with a connecting device at the end of the adsorption element for connecting to the adsorption cylinder; the first drive cylinder drives the movable seat, causing it to move along the moving shaft, the movable seat drives the adsorption element, causing it to move to target position one or target position two; the second drive cylinder drives the balance plate, causing it to move up and down; the adsorption cylinder drives the adsorption element, causing it to adsorb the workpiece located at target position one, or the adsorption cylinder drives the adsorption element to place the workpiece at target position two.

[0006] Furthermore, a first conveyor belt is provided on one side of the base, and a second conveyor belt is provided on the base, with the first conveyor belt and the second conveyor belt being arranged alternately.

[0007] Furthermore, the support frame includes columns, which are located at both ends of the second conveyor belt, and a support section is provided between the columns to support the first support plate.

[0008] Furthermore, the side of the column is provided with a groove, and the bottom of the column is provided with an L-shaped fastener, which is used to set the column on the two edges of the base through the groove.

[0009] Furthermore, several support members are provided on the conveyor belt for placing the battery cells.

[0010] Furthermore, a sensing device is also provided on the base. The sensing device is used to sense whether the support component is stopped at the target position one, so that the drive cylinder two responds to the sensing device and drives the balance plate to move above the target position.

[0011] Furthermore, the second drive cylinder includes a slide cylinder.

[0012] Furthermore, the adsorption component is provided with an elastic element.

[0013] Furthermore, a second connector is provided on the support plate, which is used to connect the moving shaft and the drive cylinder.

[0014] Furthermore, a guide rod is also provided on the support plate.

[0015] A battery cell, obtained through a battery cell transmission device; an energy storage device, comprising a battery cell, obtained through a battery cell transmission device.

[0016] A battery pack, comprising battery cells, acquired via a battery cell transfer device.

[0017] A second driving cylinder moves the balance plate up and down, adjusting the distance between the adsorption element and the battery cell. This allows the adsorption cylinder to clamp the battery cell with the adsorption element. A first driving cylinder transfers the battery cell from one transmission device to another. The second driving cylinder adjusts the distance between the battery cell and the other transmission device, preventing the battery cell from being damaged during placement or from bouncing due to inertia and colliding with other battery cells. It also integrates with other pneumatic components or systems to ensure coordination with other pneumatic devices. At least two adsorption elements are installed at both ends of the balance plate, and the second driving cylinder is used for adjustment. The distance between the adsorption element and the battery cell is precisely controlled to ensure that the cylinder is effectively adsorbed onto the adsorption surface, preventing slippage, tilting, or movement. At least two symmetrical adsorption elements hold both ends of the battery cell, and the elasticity of the adsorption elements themselves provides a certain degree of buffering and adjustment, maintaining the horizontal stability of the cylinder. This prevents the battery cell from deviating in position during movement and causing instability due to height differences when placed in another transmission device, thus preventing collisions with other battery cells. This achieves the effect of preventing collisions between battery cells during transfer. Attached Figure Description

[0026] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other. Example

[0027] like Figure 2 and Figure 3 As shown, a battery cell conveying device is provided to prevent collisions between battery cells during transfer. The device includes: a displacement frame 5 with a moving shaft 501 connected to a first drive cylinder; a movable seat 503 mounted on the moving shaft 501; a second support plate 504 mounted on the movable seat 503; a second drive cylinder mounted on the movable seat 503; and an adsorption element 801 symmetrically arranged on the opening slot, connected to an air pump. The first drive cylinder drives the movable seat 503 to move along the moving shaft 501 to a target position, the second drive cylinder drives the adsorption element 801 to move up and down, and the air pump provides negative pressure to cause the adsorption element 801 to adsorb the workpiece.

[0028] By setting a drive shaft and a movable seat 503 on the displacement frame 5, and setting a drive device to move the movable seat 503 between the two transport devices, the drive device moves the adsorption component 801 to the top of the first transport belt. The slide cylinder 7 moves the adsorption component 801 to ensure that the adsorption component 801 is in close contact with the working surface to form an adsorption force, and the battery cell will be firmly fixed on the adsorption component 801. Finally, the battery cell is smoothly transferred to another transport belt by the track system composed of the moving shaft 501 of the support plate 4. The distance between the battery cell and the other transport device is adjusted by the second drive cylinder. For example, the distance between the battery cell and the transport device is adjusted by the second drive cylinder. The spacing of 2 prevents the battery cells from being dropped or bounced from side to side during placement, thus preventing them from colliding with other battery cells and avoiding direct transfer that could cause collisions between them. The drive device is used to adjust the distance between the adsorption component 801 and the battery cell, ensuring that the cylinder is effectively adsorbed on the adsorption surface, preventing slippage, tilting or movement. At least two symmetrical adsorption components 801 hold the two ends of the battery cell, maintaining the cylinder's stability in the horizontal direction, thereby correctly positioning and balancing the height difference, preventing the battery cells from bouncing, rolling and colliding with each other after falling due to the height difference.

[0029] Specifically, the second drive cylinder includes a slide cylinder 7, which is integrated with other pneumatic components or systems to ensure coordination with other pneumatic devices and to ensure the smooth placement of the battery cells, preventing collisions between the battery cells.

[0030] Because there is a certain distance between the two ends of the cylindrical battery cell, it is difficult to ensure that the adsorption component 801 is correctly aligned. The adsorption force may be applied to one side of the battery cell, resulting in tilting or unevenness. There is a risk that the battery cell will not fall smoothly due to the unevenness at both ends, leading to collisions between the battery cells. Therefore, specifically, the drive cylinder 2 is connected to a balance plate 8, and the adsorption component 801 is symmetrically set at both ends of the balance plate 8 through the connecting device 6, thereby ensuring that the adsorption component 801 is correctly aligned, ensuring the smooth falling and placement of the battery cell, and preventing collisions between the battery cells.

[0031] Because the transmission of the cylindrical battery cells involves a drive cylinder and a slide cylinder, the adsorption component 801 may rapidly rise, fall, or stop during use. During this process, the adsorption component 801 will be subjected to additional mechanical impact, which may cause the battery cells to loosen or fall off during transmission. However, if a greater adsorption force is used, there is a risk of damaging the battery cells. Therefore, specifically, an elastic component 803, such as a spring, is provided between the adsorption component 801 and the balance plate 8 to protect the battery cells from accidental mechanical impact, ensure stable transmission of the battery cells, and prevent insufficient adsorption force during transport, which could lead to unstable descent and collisions between the battery cells.

[0032] like Figure 4 and Figure 5 As shown, due to the integrated starting element system and the short transmission path for the cylindrical battery cell, the driving cylinder continuously pushes and the conveying device continuously stops, causing the connection between the adsorption component 801 and the balance plate 8 to be constantly subjected to vibration or impact during use. The original bolt, nut, or screw fixing method may gradually loosen during use, causing the position of the adsorption component 801 relative to the balance plate 8 to change, thereby affecting the transmission of the battery cell and the stability of the positions at both ends of the cylindrical battery cell. Therefore, specifically, the balance plate 8 is provided with a receiving groove, and the balance plate 8 is also provided with an air guide groove 8041. The air guide groove 8041 is located at both ends of the receiving groove and communicates with the edge of the receiving groove; connection Device 6 also includes a connecting cover plate 8023 and a suction cup connecting sleeve 8021. The suction cup connecting sleeve 8021 is located in the receiving groove. The suction cup connecting sleeve 8021 is provided with an air guide groove 2, which is fixedly connected to the adsorption element 801. The air guide groove 2 is used to connect to the driving cylinder 3, thereby extracting the gas in the air guide groove 8041 and the air guide groove 2, so that the connecting cover plate 8023 is pressed tightly against the balance plate 8 due to negative pressure, thereby fixing the posture of the suction cup connecting sleeve 8021. It can also be integrated with other pneumatic components or systems to reduce the impact of vibration and sudden stop on the relative position of the adsorption element 801 during short-distance continuous transfer and transmission, ensuring the stable placement of the battery cell and preventing collisions between the battery cells.

[0033] Specifically, the suction cup connecting sleeve 8021 has a connecting part at the bottom. The bottom shape of the connecting part is adapted to the receiving groove. Limiting planes are provided on both sides of the connecting part, and the distance between the two movable planes is less than the distance between the two relatively connected parts of the air guide groove 8041, which restricts the circumferential positioning of the suction cup connecting sleeve 8021, further maintaining the stability of transmission and transfer, as well as the connection between the air guide groove 8041 and the air guide groove 2.

[0034] Specifically, the connecting device 6 also includes an air guide sleeve 8024. The bottom of the air guide sleeve 8024 is provided with an air guide hole 1, and the edge of the air guide hole 1 is provided with an air guide groove 3. The side of the air guide sleeve 8024 is provided with an air guide hole 2, which is connected to the air guide groove 3. This is used to cooperate with the driving cylinder 3 to extract the air from the air guide hole 1, the air guide groove 1 8041, the air guide groove 2, the air guide groove 3 and the receiving groove. This causes the connecting cover plate 8023 to be tightly pressed against the balance plate 8 due to negative pressure, so as to achieve stable gripping and fixing of the suction cup connecting sleeve 8021 connected to the adsorption component 801, thereby ensuring the smooth falling and placement of the battery cell and preventing the battery cells from colliding with each other.

[0035] Specifically, a sealing sleeve 8022 is provided on the top of the suction cup connecting sleeve 8021. The sealing sleeve 8022 abuts against the end of the air guide hole 1 to seal the gap between the suction cup connecting sleeve 8021 and the air guide hole 1, ensuring the negative pressure effect of the air guide groove 1 8041. Several connecting holes 8042 are provided on the balance plate, evenly distributed around the receiving groove. A corresponding threaded hole 1 is provided on the connecting cover plate for fixing with screws. Example

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, based on Embodiment 1, the cell transfer device further includes: a base, on which a material transfer device is provided; the material transfer device includes: a support frame 3, which is provided on the base; a displacement frame 5, which is provided on the support frame 3 and has a moving shaft 501, which is connected to a drive cylinder 1; a movable seat, which is provided on the moving shaft 501; a second support plate, which is provided on the movable seat; a second drive cylinder, which is provided on the second support plate and has a balance plate 8 at its end; and an adsorption element 801, which is provided at both ends of the balance plate 8 and has a connecting device 802 at its end for connecting to the adsorption cylinder; the first drive cylinder drives the movable seat to move along the moving shaft 501, thereby moving the adsorption element 801 to a target position 1 or a target position 2; the second drive cylinder drives the balance plate 8 to move up and down; and the adsorption cylinder drives the adsorption element 801 to adsorb the workpiece located at the target position 1, or to place the workpiece at the target position 2.

[0037] Specifically, one end of the displacement frame 5 is located above the first conveyor belt 1, and the other end is located above the second conveyor belt 2. The balance plate 8 has opening slots at both ends; the adsorption components 801 are symmetrically arranged on the opening slots, and the target position 2 is located above the second conveyor belt 2.

[0038] Specifically, the support frame 3 has columns at both ends, the columns are located at both ends of the conveyor belt 2, and the support part 4 is located between the support parts 4. The support part 4 is used to support the support plate 4.

[0039] Specifically, the column is provided with a trapezoidal groove, one end of which has an opening, and the bottom of the column is provided with an L-shaped fastener.

[0040] Specifically, the conveyor belt 1 includes a conveyor belt and a sensing device 9. The sensing device 9 is used to sense whether the support member 201 is stopped at the target position 1. The drive cylinder responds to the sensing device 9 and drives the movable seat 503 to move above the target position.

[0041] Specifically, the transport direction of the second transmission belt 2 intersects with that of the first transmission belt 1. The second transmission belt 2 is used to drive the support 201 to run in the direction of the first transmission belt, so as to ensure that the direction of the battery cell remains unchanged or rolls back and forth during transport.

[0042] Specifically, the connecting device 6 is provided with an elastic element 803, which provides a certain degree of elasticity so that the adsorption element 801 can adapt to workpiece surfaces of different shapes, bends or uneven surfaces.

[0043] When the adsorption element 801 is attached to the workpiece, the elastic element 803 can automatically adjust the contact force between the adsorption element 801 and the workpiece to achieve a better adsorption effect.

[0044] The elastic element can be a compression spring, which releases and adjusts a portion of the compression energy to provide a certain degree of buffering and adjustment, maintaining the stability of the cylinder in the horizontal direction, thereby correctly positioning and balancing the height difference, and preventing the battery cell from tilting, rolling and colliding with each other due to the height difference between the front and rear positions after falling.

[0045] Specifically, the drive cylinder includes a drive cylinder and a connecting part 2, which is used to connect the moving shaft 501 and the drive cylinder.

[0046] Specifically, the movable seat is also equipped with a guide rod 502 to increase the smooth transmission of the movable seat.
