Description

Technical Field

[0001] This utility model relates to the field of battery liquid injection technology, and in particular to a battery fixing device and a liquid injection machine. Background Technology

[0002] During the battery manufacturing process, after the battery cell is placed into the battery casing, electrolyte needs to be injected into the casing. Currently, an electrolyte injection machine is usually used to inject electrolyte into the casing.

[0003] In related technologies, liquid injection machines include a fixing component for fixing the battery and an injection component for injection. Taking a cylindrical battery as an example, the fixing component has a circular fixing hole. The cylindrical battery is inserted into the fixing hole, and its bottom is supported by a support plate to achieve positioning. However, the radial dimension of the fixing hole is usually larger than the radial dimension of the cylindrical battery, resulting in lower positioning accuracy for the cylindrical battery. Furthermore, the size of the fixing hole is usually fixed, so different fixing components are needed for cylindrical batteries of different diameters, leading to higher injection costs and lower flexibility and versatility.

[0039] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] One aspect of this application is to provide a battery fixing device, which is applied during the battery liquid filling process. It can be used to fix batteries of different sizes, improve the accuracy of fixing batteries, reduce the liquid filling cost, and has high flexibility and versatility.

[0041] For example, such as Figures 1 to 7 As shown, the battery fixing device includes a first support plate 1, a fixing mechanism 2, and a shaking mechanism 3. The fixing mechanism 2 is used to clamp and fix the battery 100, and the space in which the fixing mechanism 2 clamps and fixes the battery 100 is adjustable, thus providing high flexibility. The shaking mechanism 3 is used to drive the battery 100 to shake, thereby allowing the electrolyte to better penetrate into the battery 100.

[0042] In some embodiments, the first support plate 1 may be disposed inside the housing 5 of the injection machine. For example... Figure 3 and Figure 5 As shown, the first support plate 1 has a through hole 11 and a plurality of guide grooves 12 communicating with the through hole 11. The through hole 11 is for the battery 100 to pass through, and the guide grooves 12 have slots in the wall of the through hole 11 to communicate with it. Exemplarily, the first support plate 1 is horizontally arranged, and the axial direction of the battery 100 is the same as the thickness direction of the first support plate 1. In this embodiment, the radial dimension of the through hole 11 is larger than the radial dimension of the battery 100 to facilitate the insertion of the battery 100 into the through hole 11.

[0043] In some embodiments, the shape of the through hole 11 matches the shape of the battery 100. When the battery 100 is cylindrical, the through hole 11 is circular. When the battery 100 is polygonal, the shape of the through hole 11 can be the same polygon, and this embodiment is not limited to this. In this embodiment, the through hole 11 is circular.

[0044] In at least one embodiment, such as Figure 2 and Figure 3 As shown, the fixing mechanism 2 includes a first driving member 21, a transmission assembly 22, and multiple clamping members 23. The first driving member 21 can be disposed on the side wall 51 of the housing 5. In some optional embodiments, the first driving member 21 can be slidably disposed on the side wall 51 of the housing 5 along a first direction X. In this embodiment, the transmission assembly 22 is drively connected to the output end of the first driving member 21 and movably disposed on the first support plate 1. The output end of the first driving member 21 can drive the transmission assembly 22 to move relative to the first support plate 1. Multiple clamping members 23 are all connected to the transmission assembly 22, so that when the transmission assembly 22 moves relative to the first support plate 1, it can drive all the clamping members 23 to move relative to the first support plate 1. The first direction X is parallel to the thickness direction of the first support plate 1.

[0045] In some embodiments, multiple clamping members 23 cooperate to form a clamping space 20, which is used to clamp the battery 100. By providing multiple clamping members 23, the reliability and firmness of clamping the battery 100 can be improved. In this embodiment, there may be two or more clamping members 23, and this embodiment is not limited to this. The multiple clamping members 23 are slidably disposed in multiple guide grooves 12 in a one-to-one correspondence, so that the movement direction of the clamping members 23 relative to the first support plate 1 can be restricted by the guide grooves 12, so as to ensure that the multiple clamping members 23 can cooperate to clamp the battery 100. When the first driving member 21 drives the multiple clamping members 23 to slide in the guide grooves 12 through the transmission component 22, the size of the clamping space 20 can be adjusted, thereby adapting it to batteries 100 of different sizes.

[0046] In this embodiment, the shaking mechanism 3 is connected to the first support plate 1. The shaking mechanism 3 is used to drive the first support plate 1 to reciprocate along the first direction X, so that the first support plate 1 drives the fixing component and the battery 100 positioned by the fixing component to reciprocate along the first direction X, thereby allowing the electrolyte to better penetrate into the interior of the battery 100 and improving the electrolyte injection effect.

[0047] The battery fixing device provided in this embodiment has a first support plate 1 with a guide groove 12. The clamping members 23 of the fixing mechanism 2 are slidably disposed in the guide groove 12 one by one, so that the first driving member 21 can drive multiple clamping members 23 to slide in the guide groove 12 simultaneously through the transmission component 22. The clamping members 23 can abut against the surface of the battery 100, and thus cooperate with each other to clamp and fix the battery 100, thereby achieving the positioning of the battery 100. Furthermore, the size of the clamping space 20 formed by the clamping members 23 can be adjusted, so that the clamping members 23 can clamp according to the size of the battery 100, improving the positioning accuracy of the battery 100 and achieving the adjustment effect. This improves the flexibility and versatility of the battery fixing device and reduces the cost.

[0048] In some alternative embodiments, the first driving element 21 includes, but is not limited to, driving components such as cylinders and motors.

[0049] In some embodiments, the battery 100 may only contact the clamping member 23 without contacting the hole wall of the through hole 11 of the first support plate 1. In this case, the battery 100 can be clamped and fixed by multiple clamping members 23.

[0050] In other embodiments, multiple clamping members 23 may cooperate with the first support plate 1 to clamp the battery 100. That is, the battery 100 not only contacts the clamping members 23, but also contacts the hole wall of the through hole 11, so that the first support plate 1 and the clamping members 23 cooperate to clamp the battery 100, and the battery 100 can also be positioned.

[0051] The transmission assembly 22 can have various specific structures; this embodiment exemplarily provides one such transmission assembly 22. In one or more embodiments of this application, such as... Figure 3 As shown, the transmission assembly 22 includes a transmission group 221 and a rotating disk 222. The rotating disk 222 is rotatably mounted on the first support plate 1 and has a central hole 2221. The central hole 2221 corresponds to and communicates with the through hole 11 of the first support plate 1, allowing the battery 100 to pass through the central hole 2221. In some embodiments, the central hole 2221 and the through hole 11 can be coaxial, the same size, and the same shape.

[0052] It should be noted that, as Figure 2 As shown, the rotating disk 222 is rotatably disposed on the top surface of the first support plate 1, and the battery 100 is disposed through the central hole 2221 and the through hole 11 of the rotating disk 222. In other optional embodiments, the rotating disk 222 may also be rotatably disposed on the bottom surface of the first support plate 1, but this embodiment does not limit this.

[0053] In some optional embodiments, the first driving member 21 is connected to the transmission group 221, that is, the output end of the first driving member 21 is connected to the transmission group 221, and the transmission group 221 is connected to the rotating disk 222. When the first driving member 21 drives the transmission group 221 to operate, the transmission group 221 can drive the rotating disk 222 to rotate relative to the first support plate 1. When the rotating disk 222 rotates relative to the first support plate 1, it can drive the clamping member 23 to slide in the guide groove 12, thereby adjusting the size of the clamping space 20.

[0054] In one or more embodiments of this application, please continue to refer to Figure 3 The rotating disk 222 is provided with a drive hole 2222, and the clamping member 23 is provided with a first drive shaft 231. The first drive shaft 231 is slidably disposed in the drive hole 2222 along the extension direction of the drive hole 2222. When the rotating disk 222 rotates relative to the first support plate 1, it can push the first drive shaft 231 to move through the hole wall of the drive hole 2222, thereby causing the first drive member 21 to drive the clamping member 23 to slide in the guide groove 12, realizing the mutual approach or distance of multiple clamping members 23, thereby achieving the purpose of adjusting the size of the clamping space 20. By setting the drive hole 2222 and the first drive shaft 231, the connection between the rotating disk 222 and the clamping member 23 is relatively simple and has high reliability. The drive hole 2222 can guide the movement of the first drive shaft 231, so that the first drive shaft 231 and the clamping member 23 can move along the extension direction of the drive hole 2222.

[0055] In at least one possible embodiment, the extending direction of the drive hole 2222 intersects both the circumferential direction of the rotating disk 222 and the length direction of the guide groove 12. That is, the extending direction of the drive hole 2222 is neither the same as the circumferential direction of the rotating disk 222 nor the same as the length direction of the guide groove 12, but is inclined. The rotation direction of the rotating disk 222 relative to the first support plate 1 is in the same direction as the circumferential direction of the rotating disk 222, while the extending direction of the drive hole 2222 intersects the rotation direction of the rotating disk 222. This causes the hole wall of the drive hole 2222 to push the first drive shaft 231 to move when the rotating disk 222 rotates, and the clamping member 23 is slidably disposed in the guide groove 12 along the length direction of the guide groove 12. Therefore, under the push of the hole wall of the drive hole 2222, the clamping member 23 slides in the guide groove 12. When the rotating disk 222 rotates in the first rotation direction, the clamping member 23 can move closer to the battery 100 along the length direction of the guide groove 12 to clamp the battery 100. When the disk rotates in the opposite direction of the first rotation direction, the clamping member 23 can move away from the battery 100 along the length direction of the guide groove 12 to release the battery 100. Optionally, the first driving member 21 can drive the rotating disk 222 to rotate in the first rotation direction and in the opposite direction of the first rotation direction through the transmission assembly 221 to improve the degree of automation.

[0056] In some embodiments, the length direction of the guide groove 12 may be the same as the radial direction of the rotating disk 222, so that when the clamping member 23 slides in the guide groove 12, it can approach or move away from the center of the central hole 2221 of the rotating disk 222, thereby clamping or releasing the battery 100. Of course, it is understood that the length direction of the guide groove 12 may also intersect with the radial direction of the rotating disk 222, and this embodiment does not limit this.

[0057] In one or more embodiments of this application, such as Figure 3 As shown, the transmission assembly 221 is provided with a first tooth structure 24, and the rotating disk 222 is provided with a second tooth structure 25. The first tooth structure 24 and the second tooth structure 25 mesh, enabling the transmission assembly 221 and the rotating disk 222 to be connected by transmission through the meshing first tooth structure 24 and the second tooth structure 25. Exemplarily, both the first tooth structure 24 and the second tooth structure 25 include multiple teeth. The multiple teeth of the first tooth structure 24 are spaced apart along the circumferential direction of the rotating disk 222, and the multiple teeth of the second tooth structure 25 are spaced apart along the length direction of the first support plate 1. The transmission assembly 221 can move along the length direction of the first support plate 1, thereby driving the rotating disk 222 to rotate through the first tooth structure 24 and the second tooth structure 25.

[0058] In some alternative embodiments, the first tooth structure 24 is disposed on the surface of the rotating disk 222 opposite to the first support plate 1, so as to facilitate the meshing of the first tooth structure 24 with the second tooth structure 25.

[0059] It is understood that in other alternative embodiments, the first tooth structure 24 may also be disposed on the circumferential surface of the rotating disk 222, and this embodiment does not limit this.

[0060] In some embodiments, this embodiment provides a transmission assembly 221. For example... Figure 4 and Figure 5 As shown, the transmission assembly 221 includes a lead screw 2211, a first moving member 2212, and a rack 2213. The first driving member 21 drives the lead screw 2211 to rotate. In this embodiment, the first driving member 21 can be a motor. The first driving member 21 outputs torque to the lead screw 2211 to drive its rotation. In this embodiment, the axial direction of the lead screw 2211 is perpendicular to the thickness direction of the first support plate 1. For example, the lead screw 2211 can extend along the tangent direction of the rotating disk 222. The first moving member 2212 is sleeved on the lead screw 2211 and threadedly connected to it. That is, the first moving member 2212 has an internal thread. When the lead screw 2211 rotates, it can drive the first moving member 2212 to move along the axial direction of the lead screw 2211. The rack 2213 is connected to the first moving member 2212, so that when the first moving member 2212 moves along the axis of the lead screw 2211, it can drive the rack 2213 to move in the same direction. The first tooth structure 24 is provided on the rack 2213, that is, the teeth on the rack 2213 constitute the first tooth structure 24.

[0061] In at least one embodiment, the first moving member 2212 may include a reciprocating threaded sleeve (not shown in the figure) and a connecting portion (not shown in the figure). The reciprocating threaded sleeve is fitted onto the lead screw 2211 and threadedly connected to the lead screw 2211. The connecting portion is connected to the reciprocating threaded sleeve such that when the reciprocating threaded sleeve moves along the axial direction of the lead screw 2211, the connecting portion moves synchronously. The rack 2213 is connected to the connecting portion such that the rack 2213 can move synchronously with the connecting portion. In some optional embodiments, the first support plate 1 may be provided with a sliding hole, the length direction of which is the same as the axial direction of the lead screw 2211. A portion of the connecting portion slides in the sliding hole, thereby ensuring that the movement direction of the connecting portion is the same as the axial direction of the lead screw 2211. By providing the connecting portion, a larger connection area can be provided between the rack 2213 and the first moving member 2212, thereby ensuring the connection strength.

[0062] In one or more embodiments of this application, such as Figure 5As shown, the first support plate 1 is provided with an arc-shaped groove 13, and the rotating disk 222 is connected to a second moving member 223. The second moving member 223 is slidably disposed in the arc-shaped groove 13 along its extension direction. The extension direction of the arc-shaped groove 13 is the same as the circumferential direction of the through hole 11. By providing the arc-shaped groove 13, the rotation of the rotating disk 222 can be guided, and the rotation of the rotating disk 222 can be made more stable.

[0063] In some embodiments, multiple arc-shaped grooves 13 may be provided at intervals, and correspondingly, multiple second moving members 223 are provided. The second moving members 223 are slidably disposed in the corresponding arc-shaped grooves 13 to further improve the stability and directionality of the rotation of the rotating disk 222. In addition, by providing segmented arc-shaped grooves 13, the arc-shaped grooves 13 can limit the rotation limit of the rotating disk 222, reducing the possibility of excessive rotation of the rotating disk 222. This indirectly limits the minimum area of ​​the clamping space 20 formed by the clamping member 23, thereby reducing the risk of the clamping member 23 damaging the battery 100 and improving safety and reliability.

[0064] In other embodiments, the arc groove 13 can also be an annular groove, and the second moving member 223 is provided with one or more, so that it can also be used as a guide for the rotating disk 222.

[0065] In one or more embodiments of this application, multiple fixing mechanisms 2 may be provided, and multiple fixing mechanisms 2 are spaced apart on the first support plate 1. In this embodiment, multiple fixing mechanisms 2 may share a first driving member 21 and a lead screw 2211. At this time, the first driving member 21 drives the lead screw 2211 to rotate, and the lead screw 2211 can drive multiple racks 2213 to move, thereby causing the racks 2213 to drive multiple rotating disks 222 to rotate, realizing the synchronous adjustment of multiple clamping spaces 20 and improving the injection efficiency.

[0066] In one or more embodiments of this application, such as Figure 2 and Figure 4 As shown, the battery fixing device also includes a second support plate 4. The second support plate 4 is disposed opposite to the first support plate 1 along a first direction X. In some embodiments, the first support plate 1 and the second support plate 4 are parallel to each other. The second support plate 4 is disposed below the first support plate 1.

[0067] Exemplarily, this embodiment provides a shaking mechanism 3. Please refer to... Figure 2 and Figure 7The shaking mechanism 3 includes a second driving member 31, a pushing component 32, and an elastic reset component 33. The pushing component 32 is located on the side of the first support plate 1 opposite to the second support plate 4. The second driving member 31 drives the pushing component 32 to periodically push the first support plate 1 closer to the second support plate 4. The elastic reset component 33 is located between the first support plate 1 and the second support plate 4 and is used to reset the first support plate 1, thus realizing the shaking of the first support plate 1 in the first direction X. When the first support plate 1 shakes in the first direction X, it can cause the battery 100 to shake in the first direction X through the fixing mechanism 2, thereby allowing the electrolyte to better penetrate into the battery 100 and improving the electrolyte injection efficiency of the injection machine.

[0068] It should be noted that the second driving component 31 may include, but is not limited to, driving components such as motors and cylinders. The second driving component 31 may be disposed on the side wall 51 of the housing 5. In some embodiments, the periodic pushing of the first support plate 1 by the pushing component 32 means that the pushing component 32 pushes the first support plate 1 once every certain period of time (e.g., 2 seconds, 5 seconds, 10 seconds, etc.).

[0069] It should also be noted that when the first support plate 1 moves closer to the second support plate 4 under the push of the push component 32, it compresses the elastic reset member 33. This allows the elastic force of the elastic reset member 33 to push the first support plate 1 away from the second support plate 4 when the push component 32 no longer applies force to the first support plate 1, thereby resetting the first support plate 1. Exemplarily, the elastic reset member 33 can be a spring, elastic strip, or other component capable of elastic deformation; this embodiment does not limit this.

[0070] In some embodiments, such as Figure 7 As shown, the pushing assembly 32 includes a second drive shaft 321 and a push rod 322. The second drive shaft 321 is connected to a second drive member 31, which drives the second drive shaft 321 to rotate. One end of the push rod 322 is connected to the second drive shaft 321, and the other end of the push rod 322 abuts against the first support plate 1. The second drive member 31 drives the second drive shaft 321 to rotate, causing the second drive shaft 321 to drive the push rod 322 to rotate. This causes the end of the push rod 322 abutting against the first support plate 1 to push the first support plate 1 closer to the second support plate 4. When the push rod 322 leaves the first support plate 1, the first support plate 1 is reset by the action of the elastic reset member 33.

[0071] In at least one embodiment, the second driving member 31 can drive the second driving shaft 321 to rotate one revolution. During this process, the push rod 322 pushes the first support plate 1 to gradually approach the second support plate 4. When the distance between the first support plate 1 and the second support plate 4 reaches its minimum, the push rod 322 is perpendicular to the first support plate 1. Then, under the action of the elastic reset member 33, the first support plate 1 gradually moves away from the second support plate 4 until it is reset.

[0072] In some embodiments, please continue to see Figure 2 and Figure 4 The shaking mechanism 3 also includes a guide rod 34 and a limiting block (not shown in the figure). One end of the guide rod 34 is connected to the first support plate 1, and the other end of the guide rod 34 slidably passes through the second support plate 4 and is connected to the limiting block. By setting the guide rod 34, the movement of the first support plate 1 can be guided, ensuring the directionality and stability of the movement of the first support plate 1. By setting the limiting block, the limiting block is always located on the side of the second support plate 4 opposite to the first support plate 1, which can limit the maximum distance between the first support plate 1 and the second support plate 4, ensuring the smooth reset of the first support plate 1.

[0073] In at least one embodiment, the elastic reset member 33 is sleeved on the guide rod 34, so that the guide rod 34 can support the elastic reset member 33, reduce the risk of the elastic reset member 33 tilting, and thus ensure that the first support plate 1 can be reset.

[0074] The battery fixing device provided in this embodiment uses a first drive shaft 231 fixed to the top of the clamping member 23 to slide on the inner wall of the rotating disk 222, thereby forcing the clamping member 23 to slide on the inner wall of the guide groove 12, thus clamping the outer surface of the battery 100. Furthermore, the reciprocating motion of the reciprocating threaded part allows the clamping member 23 to clamp according to the size of the battery 100, achieving an adjustment effect and improving the performance of the electrolyte injection machine. The push rod 322 follows the second drive shaft 321 in an arc-shaped motion, causing the push rod 322 to intermittently push the first support plate 1, causing the guide rod 34 to be forced to move the first support plate 1 downwards. The guide rod 34 is then reset by the elastic force of the elastic reset member 33, achieving the extension and retraction of the guide rod 34, resulting in the shaking of the battery 100, allowing the electrolyte to better penetrate the battery 100.

[0075] In another aspect of this application, this embodiment also provides a liquid injection machine, including the aforementioned battery fixing device. The liquid injection machine provided in this embodiment has a wide range of applications and high flexibility.

[0076] Optionally, the liquid injection machine includes a housing 5, with the first support plate 1 and the second support plate 4 both located inside the housing 5. The other components of the fixing mechanism 2, except for the first driving member 21, are also located inside the housing 5. The other components of the shaking mechanism 3, except for the second driving member 31, are also located inside the housing 5.

[0077] The process of using the liquid injection machine provided in this embodiment is as follows: First, when liquid injection processing is required for the battery 100, the battery 100 needs to be placed in the through hole 11 of the first support plate 1, and the external power supply is turned on so that the liquid injection machine starts to inject liquid. However, since the battery 100 is of different models, in order to improve the performance of the liquid injection machine, when the battery 100 is placed in the through hole 11 of the first support plate 1, the control device of the liquid injection machine can control the first driving member 21 to start, so that the first driving member 21 drives the lead screw 2211 to rotate, and drives the reciprocating threaded part of the first moving member 2212 to achieve reciprocating linear motion through the sliding of the connecting part. When the first moving member 2212 moves, it drives the rack 2213 to move, that is, the rack 2213 can be driven to perform reciprocating linear motion. When the rack 2213 moves, it drives the rotating disk 222 to rotate through the first tooth structure 24 and the second tooth structure 25, so that the rotating disk 222 is subjected to force and slides on the inner wall of the arc groove 13 through the second moving member 223. Furthermore, when the rotating disk 222 rotates, the first drive shaft 231 is driven by the drive hole 2222 to slide on the hole wall of the drive hole 2222, thereby forcing the clamping member 23 to slide on the inner wall of the guide groove 12, thereby clamping the outer surface of the battery 100. Moreover, through the reciprocating motion of the reciprocating thread sleeve, the clamping member 23 can clamp according to the size of the battery 100, achieving an adjustment effect and improving the performance of the liquid injection machine.

[0078] By activating the second driving component 31, the second driving shaft 321 rotates, thereby driving the push rod 322 to rotate. When the push rod 322 moves, it intermittently pushes the first support plate 1, causing the guide rod 34 to be forced to move the first support plate 1 downwards towards the second support plate 4. The guide rod 34 is then reset by the elastic force of the elastic reset component 33, achieving the extension and retraction of the guide rod 34. This vibration of the battery 100 allows the electrolyte to better penetrate into the battery 100. During the electrolyte injection process, the vibration of the battery 100 reduces air bubbles inside the battery 100, allowing for better electrolyte penetration.
