Description
Technical Field
[0001] This utility model relates to the field of cylindrical battery production technology, and in particular to a clamping device and a cylindrical battery production line. Background Technology
[0002] In cylindrical battery production lines, cylindrical batteries are typically transported in trays to minimize damage during transport. However, placing batteries in trays makes them difficult for robots to handle. Firstly, the probability of failure or damage during handling is higher; secondly, the structure is more complex.
[0003] Therefore, there is an urgent need for a clamping device and a cylindrical battery production line to solve the above problems. Utility Model Content
[0004] Based on the above, one of the objectives of this utility model is to provide a clamping device that can clamp the entire unit to be clamped, consisting of a cylindrical battery and a cup holder. The device has a simple structure and high clamping reliability.
[0005] To achieve the above objectives, firstly, the present invention adopts the following technical solution:
[0006] A clamping device for clamping a unit to be clamped, the unit to be clamped including a cup and a cylindrical battery placed inside the cup, the cylindrical battery having a first end placed inside the cup and a second end opposite to the first end; the clamping device includes:
[0007] The clamping body extends along the first direction;
[0008] Multiple clamping components are disposed on the clamping body. Each clamping component includes two clamping claws spaced apart along a second direction. One of the two clamping claws can be connected to the first end and / or the cup to form a first clamping claw, and the other can be connected to the second end to form a second clamping claw. The first clamping claw and the second clamping claw can approach each other to clamp the unit to be clamped.
[0009] The second direction is perpendicular to the first direction.
[0010] The beneficial effects of the above technical solution are as follows:
[0011] By incorporating a clamping main body to integrate multiple clamping components, the number of units that can be clamped at once is increased, thus improving clamping efficiency. The clamping components include two jaws: a first jaw for connecting to the first end and / or the support cup of the cylindrical battery, and a second jaw for connecting to the second end of the cylindrical battery. When the first and second jaws approach each other, the unit to be clamped is clamped. This not only avoids damage to the cylindrical battery caused by placing it alone, but also simplifies the clamping process compared to clamping a cylindrical battery individually, resulting in a simpler structure and lower clamping difficulty. The extension direction of the clamping main body is perpendicular to the direction in which the two jaws approach each other, preventing excessive space occupation in the first direction during clamping and allowing the clamping device to accommodate a larger number of clamping components.
[0012] The second objective of this invention is to provide a cylindrical battery production line that makes the transportation and clamping of cylindrical batteries safer and more reliable.
[0013] To achieve the above objectives, in a second aspect, the present invention adopts the following technical solution:
[0014] A cylindrical battery production line, including the clamping device described in any of the above solutions.
[0015] The beneficial effects of the above technical solution are as follows:
[0016] In a cylindrical battery production line equipped with the aforementioned clamping device, cylindrical batteries can be placed in a tray for transport and can be clamped as a whole, making clamping easier and more reliable. Attached Figure Description

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0037] A cylindrical cell is a miniaturized battery unit encapsulated in a cylindrical metal casing, with an internal wound structure (comprising a positive electrode, negative electrode, separator, and electrolyte) for storing and releasing electrochemical energy. It is one of the earliest industrialized and most technologically mature types of lithium-ion batteries among the three main types (cylindrical, prismatic, and pouch). Essentially, the cylindrical cell has a cylindrical casing with an internal cylindrical cavity. The casing material can be aluminum, aluminum alloy, or a composite metal material. In the assembly of lithium-ion battery packs (such as consumer electronics, energy storage, and power battery packs), two cylindrical cells are welded together using connecting tabs to achieve "series / parallel connection." Its core function is to establish a stable current path to meet the voltage and capacity requirements of different scenarios.
[0038] like Figures 1-7 As shown, this embodiment provides a clamping device for clamping a unit 100 to be clamped. The unit 100 to be clamped includes a cup 110 and a cylindrical battery 120 placed inside the cup 110. The cylindrical battery 120 has a first end 121 placed inside the cup 110 and a second end 122 opposite to the first end 121. The clamping device includes a clamping body 200 and a plurality of clamping components 300. The clamping body 200 extends along a first direction. The plurality of clamping components 300 are all disposed on the clamping body 200. Each clamping component 300 includes two jaws 310 spaced apart along a second direction. One of the two jaws 310 can be connected to the first end 121 and / or the cup 110 to form a first jaw 320, and the other can be connected to the second end 122 to form a second jaw 330. The first jaw 320 and the second jaw 330 can approach each other to clamp the unit 100 to be clamped. The second direction is perpendicular to the first direction.
[0039] By incorporating a clamping body 200 to integrate multiple clamping components 300, the number of units 100 that can be clamped at once by the clamping device is increased, thereby improving clamping efficiency. Each clamping component 300 includes two grippers 310: a first gripper 320 for connecting to the first end 121 of the cylindrical battery 120 and / or the cup 110, and a second gripper 330 for connecting to the second end 122 of the cylindrical battery 120. When the first gripper 320 and the second gripper 330 approach each other, the unit 100 can be clamped. This not only avoids damage to the cylindrical battery 120 caused by placing it alone, but also simplifies the clamping process compared to clamping the cylindrical battery 120 individually, resulting in a simpler structure and lower clamping difficulty. The extension direction of the clamping body 200 is perpendicular to the direction in which the two grippers 310 approach each other, preventing excessive space occupation in the first direction during clamping and allowing the clamping device to accommodate a larger number of clamping components 300.
[0040] It is understood that the first end 121 and the second end 122 are the two ends of the cylindrical battery 120 along its axial direction. The clamping device can clamp the unit 100 to be clamped, whose axis extends along the second direction. During clamping, the first jaw 320 and the second jaw 330 abut against the two ends of the unit 100 to be clamped. When the two jaws 310 move away from each other, they are used to lower the unit 100 to be clamped. In addition, the first direction and the second direction are two mutually perpendicular directions, wherein the first direction is the extension direction of the clamping body 200 and the arrangement direction of the plurality of clamping components 300; the second direction is the relative movement direction of the first jaw 320 and the second jaw 330 and the axial extension direction of the unit 100 to be clamped when the clamping device clamps the unit 100 to be clamped.
[0041] To improve the reliability of the clamping device in fixing the clamping unit 100, the clamping device also includes an adsorption component 400. The adsorption component 400 is disposed between the two grippers 310. When the clamping component 300 clamps the clamping unit 100, the adsorption component 400 can adsorb onto the cylindrical battery 120 and / or the cup 110, thereby reducing the risk of the clamping unit 100 falling off.
[0042] Specifically, the adsorption assembly 400 is provided with multiple suction nozzles, which are spaced apart along a second direction. The second direction is the extension direction of the axis of the unit to be clamped 100. Therefore, by providing multiple suction nozzles spaced apart along the second direction, they can be adsorbed onto the unit to be clamped 100 at multiple positions along the axis, resulting in a better anti-fall-off effect.
[0043] Furthermore, among the multiple nozzles, some nozzles can adhere to the cylindrical battery 120, while the remaining nozzles can adhere to the cup 110. This means that both the cylindrical battery 120 and the cup 110 can be adhered to simultaneously, resulting in higher adhesion reliability. Those skilled in the art can determine the appropriate number of nozzles to use with the cylindrical battery 120 and the cup 110 based on actual needs to ensure optimal adhesion; no specific limitations are made here.
[0044] In this embodiment, the projected area of the suction nozzle on the cylindrical battery 120 is set to 1000 mm². 2 -5000mm 2 If the projected area is set too small, the adsorption force weakens, resulting in a poorer overall adsorption effect. If the projected area is set too large, the adhesion between the nozzle and the outer wall of the cylindrical battery 120 will be poor, making it prone to air leakage and causing adsorption failure. For example, the projected area of the nozzle on the cylindrical battery 120 is set to 1000 mm². 2 2000mm 2 3000mm 2 4000mm 2 5000mm 2 Alternatively, the nozzle may be oval in shape, with an outline size of 30mm × 60mm; in addition, the cylindrical battery 120 has a diameter of approximately 46mm.
[0045] Preferably, the second end 122 is provided with a functional part 123. By positioning the end of the cylindrical battery 120 with the functional part 123 on the outside of the cup 110, damage to the functional part 123 by the cup 110 can be reduced. Optionally, the functional part 123 can be an electrode post, an explosion-proof valve, or other parts to avoid stress concentration. For example, the area of the functional part 123 is 200 mm². 2 -250mm 2An excessively small functional part 123 increases the difficulty of its design, while an excessively large functional part 123 occupies too much space on the second end 122. The area of the functional part 123 could be set to 200 mm². 2 210mm 2 220mm 2 230mm 2 240mm 2 250mm 2 etc., or any value that meets the above-mentioned requirements.
[0046] In one embodiment, the second gripper 330 is provided with a clearance structure 331. By providing a clearance structure 331 corresponding to the functional part 123, the risk of the functional part 123 being pinched and damaged by the second gripper 330 when clamping the unit to be clamped 100 can be reduced. Optionally, the area of the clearance structure 331 is larger than the area of the functional part 123. In this case, the clearance structure 331 can be set as a clearance groove, and the shape of the clearance groove is adapted to the shape of the functional part 123. Alternatively, the clearance structure 331 can also be set as a buffer layer to avoid the risk of damage caused by rigid connection through flexible fit. Exemplarily, the ratio of the area of the clearance structure 331 to the area of the functional part 123 is set to ensure the reliability of clamping while reducing the clamping difficulty. When the ratio of the area of the clearance structure 331 to the area of the functional part 123 is set too small, the difficulty of the cooperation between the clearance structure 331 and the functional part 123 increases, requiring the clamping device to have higher clamping accuracy. When the ratio of the area of the avoidance structure 331 to the area of the functional part 123 is set too large, although the clamping difficulty is reduced, the mating area between the second gripper 330 and the second end 122 is reduced, and the clamping reliability is reduced.
[0047] Alternatively, the functional part 123 can be configured to extend at least partially out of the avoidance structure 331. In this case, the avoidance structure 331 can be configured as an avoidance notch, and the functional part 123 is configured to correspond to the avoidance notch. Furthermore, the functional part 123 can extend at least partially out of the avoidance structure 331, meaning that some functional parts 123 do not correspond to the second gripper 330. In this case, the size of the second gripper 330 can be reduced.
[0048] In another embodiment, the second gripper 330 may not have the clearance structure 331. The second gripper 330 connects to the position of the second end 122 where the functional part 123 is not provided, thereby achieving the clamping of the cylindrical battery 120. This clamping method can also reduce the damage to the functional part 123 caused by the clamping operation.
[0049] As an optional clamping device, since the spacing between the cylindrical batteries 120 required for different processes varies, the clamping device is also equipped with a pitch-changing assembly 500. The pitch-changing assembly 500 includes a pitch-changing drive 510 and pitch-changing ends 520. The clamping assembly 300 is disposed at the pitch-changing end 520. The pitch-changing drive 510 can drive multiple pitch-changing ends 520 to have a preset distance between them, thereby ensuring that the distance between multiple units 100 to be clamped meets the process requirements. Of course, it is understandable that the pitch-changing assembly 500 can also change the pitch before clamping, thus enabling the same clamping device to clamp units 100 of different sizes, which helps improve the versatility of the clamping device.
[0050] Specifically, the ratio of the preset distance of the clamping component 300 to the length of the clamping body 200 is set to 0.65-0.92. This ratio helps optimize the specific settings of the clamping component 300 while ensuring clamping reliability. If the ratio is set too small, the preset distance of the clamping component 300 is too small, wasting space in the clamping body 200 and reducing economic efficiency. If the ratio is set too large, the clamping component 300 occupies too much space in the clamping body 200, easily leading to clamping failure and reducing the reliability of the clamping device. For example, the ratio can be set to 0.65, 0.67, 0.68, 0.70, 0.72, 0.74, 0.76, 0.78, 0.79, 0.82, 0.84, 0.86, 0.88, 0.90, 0.92, or any value satisfying the above-defined limits.
[0051] It is worth noting that the clamping unit 100, composed of the cylindrical battery 120 and the cup 110, has both horizontal (the axis of the cylindrical battery 120 extends along a horizontal plane) and vertical (the axis of the cylindrical battery 120 extends along a vertical plane) conveying modes. Therefore, to achieve the flipping of the clamping unit 100, the clamping device also includes a flipping component 620 to switch the second direction between the horizontal and vertical planes. When the second direction extends along the horizontal plane, the clamping unit 100 is placed horizontally; when the second direction extends along the vertical plane, the clamping unit 100 is placed vertically.
[0052] Specifically, to provide space for the flipping action, the clamping device is also equipped with a lifting assembly 610. The clamping body 200 is located at the lifting end of the lifting assembly 610, which is used to raise and lower the clamping body 200. That is, after clamping is completed, the clamping body 200 needs to be raised a certain distance to avoid interference during the flipping process. Furthermore, the lifting assembly 610 is located at the flipping end of the flipping assembly 620, which is used to flip the lifting assembly 610 and simultaneously flip the clamping body 200.
[0053] Furthermore, the clamping device also includes a translation component 630, and a flipping component 620 is disposed on the translation component 630. The translation component 630 is used to translate the flipping component 620. By providing the translation component 630, the clamping device also has the function of transporting the clamped unit 100, increasing the functionality of the clamping device and expanding its usability scenarios. Exemplarily, the specific arrangements of the lifting component 610, the flipping component 620, and the translation component 630 described above are understandable and achievable by those skilled in the art, and will not be elaborated further here.
[0054] It is understood that the clamping device, by setting up the lifting component 610, the flipping component 620, and the translation component 630, can achieve flipping and transportation. When the flipping component 620 is not working, the clamping component 300 can clamp the unit 100 to be clamped and lift it up, and then transport it directly, thus ensuring that the unit 100 to be clamped is transported in the same state. Those skilled in the art can select and set the clamping device according to its position relative to the cylindrical battery 120 production line, and the state of the unit 100 to be clamped required for the processes before and after that position, without making specific limitations here.
[0055] As an alternative clamping device, the first gripper 320 is provided with a first clamping claw 321 and a second clamping claw 322. The first clamping claw 321 can be connected to the first end 121, and the second clamping claw 322 can be connected to the cup holder 110. That is, the first gripper 320 is connected to both the first end 121 and the cup holder 110 simultaneously, making the clamping more reliable. Furthermore, the integrated arrangement of the first clamping claw 321 and the second clamping claw 322 is more conducive to structural simplification, facilitates synchronous driving, improves clamping synchronization, and enhances clamping reliability.
[0056] To achieve the engagement between the first gripper 320 and the first end 121, the side wall of the cup 110 is provided with a first clamping through hole 111 communicating with the first end 121. During clamping, the first gripper 320 can pass through the first clamping through hole 111 and connect with the first end 121. It is worth noting that in both conveying methods, when the first gripper 320 is only connected and engaged with the first end 121, it is necessary to ensure the engagement relationship between the cylindrical battery 120 and the cup 110 to ensure the integrity of the unit 100 to be clamped.
[0057] For example, if the clamping unit 100 is placed horizontally, the cup 110 can remain attached to the cylindrical battery 120 by gravity; if the clamping unit is placed vertically, the cup 110 can connect the upper top wall of the first clamping through hole 111 to the first gripper 320 by gravity, thereby ensuring the integrity of the clamping unit 100.
[0058] As another option for the first gripper 320 to engage with the first end 121, the bottom of the cup holder 110 is provided with a second clamping through hole communicating with the first end 121. During clamping, the first gripper 320 can pass through the second clamping through hole and connect with the first end 121. Compared to the first gripper 320 connecting with the first end 121 via the first clamping through hole 111, the option using the second through hole to engage with the first end 121 is only suitable for scenarios where the unit 100 to be clamped is placed vertically. However, the option with the first clamping through hole 111 does not affect the clamping operation of the clamping device regardless of whether the unit 100 to be clamped is placed horizontally or vertically.
[0059] In other embodiments, the first gripper 320 may also be connected to the cup holder 110. Optionally, the bottom of the cup holder 110 is provided with a relief groove 112, within which the first gripper 320 can be placed. The relief groove 112 facilitates guidance for the engagement of the first gripper 320 and the cup holder 110. Preferably, the depth of the relief groove 112 is greater than the thickness of the first gripper 320. This design allows the clamping of the unit 100 to be held even when it is placed vertically, by using the first gripper 320 to engage with the cup holder 110, thus increasing the applicability of this solution.
[0060] For example, the depth of the clearance groove 112 is set to 10mm-15mm, and the thickness of the first gripper 320 is set to 5mm-10mm. By setting these parameters, it is ensured that the first gripper 320 can smoothly enter and exit the clearance groove 112 when the unit to be gripped 100 is placed vertically, reducing positioning difficulty. If the depth of the clearance groove 112 is too small, the reserved space will be too small, increasing positioning difficulty; if it is too large, it will increase the volume of the cup holder 110, resulting in unnecessary waste. Optionally, the depth of the clearance groove 112 can be set to 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., or satisfy any of the above-defined values. If the thickness of the first gripper 320 is too large, it will increase the difficulty of entering and exiting the clearance groove 112; if it is too small, it will reduce the gripping force. Optionally, the thickness of the first gripper 320 can be set to 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc., or satisfy any of the above-defined values.
[0061] Preferably, the cup holder 110 is further provided with an orientation structure 113, which is used to display the circumferential position of the cup holder 110 relative to the first gripper 320. That is, the positioning structure facilitates the operator or machine vision to obtain the circumferential position of the cup holder 110 in a timely manner. Especially when the cup holder 110 is provided with the aforementioned first clamping through hole 111, second clamping through hole, and clearance groove 112, the positioning structure improves the reliability of clamping.
[0062] As an alternative to the clamping device, the clamping assembly 300 is also provided with a drive member 340, which is used to drive the first jaw 320 and / or the second jaw 330 to move so that the two jaws 310 move closer to each other for clamping.
[0063] Preferably, the driving member 340 is used to drive the second gripper 330 to move closer to or further away from the first gripper 320. That is, the first gripper 320 is fixedly disposed on the clamping body 200, and the second gripper 330 moves relative to the clamping body 200 through the driving member 340. Since the first end 121 of the cylindrical battery 120 cooperates with the cup 110, the first gripper 320 requires more cooperation and has higher positioning accuracy. However, the space where the second end 122 is located is larger. Therefore, fixing the first gripper 320 makes it easier to clamp, while only driving the second gripper 330 simplifies the driving structure.
[0064] Specifically, the gripper 310 includes an installation portion 311 and a clamping portion 312 connected to each other. The installation portion 311 is used to install the gripper 310. The installation portion 311 of the first gripper 320 is connected to the clamping body 200, and the clamping portion 312 is used to connect to the first end 121 and / or the cup holder 110. The installation portion 311 of the second gripper 330 is connected to the drive member 340, and the clamping portion 312 is used to connect to the second end 122.
[0065] It is worth noting that the clamping part 312 is set perpendicular to both the first and second directions, which is more conducive to optimizing the spatial layout and reducing interference between clamping components 300 and between clamping components 300 and clamping body 200.
[0066] This embodiment also discloses a cylindrical battery production line, including the clamping device described in any of the above embodiments. In the cylindrical battery 120 production line equipped with the above-mentioned clamping device, the cylindrical battery 120 can be placed in the cup 110 for transport, and the entire clamping unit 100 can be clamped, making clamping easier and more reliable.
[0067] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
