[0047] During battery manufacturing, such as when manufacturing lithium-ion batteries, electrolyte needs to be injected into the battery through a liquid injection process. Any electrolyte residue left at the battery injection port needs to be wiped off promptly to avoid contaminating the battery and the environment.

[0048] Reference Figure 1 and Figure 2 This application provides a wiping head 100 for wiping the electrolyte filling port of a battery 500. The wiping head 100 includes:

[0049] Body 1, body 1 has a wiping surface 11;

[0050] The protrusion 2 is provided on the wiping surface 11, and the shape of the protrusion 2 can be adapted to the liquid filling port of the battery 500.

[0051] In the above embodiment, when the wiping head 100 wipes the liquid filling port of the battery 500, the wiping surface 11 of the body 1 faces the liquid filling port of the battery 500, and the wiping head 100 can effectively clean the liquid filling port of the battery 500 when it rotates.

[0052] See Figures 1 to 4 The protrusion 2 can be integrally formed with the body 1 to ensure the structural strength and integrity of the wiping head 100; or the protrusion 2 can be detachably fixed to the wiping surface 11 of the body 1 to facilitate the disassembly and replacement of the protrusion 2 and improve the adaptability of the wiping head 100.

[0053] In the above embodiment, the shape of the protrusion 2 can be adapted to the liquid filling port of the battery 500, and the wiping head 100 can closely fit the edge and inside of the liquid filling port to effectively remove tiny particles, liquid residues, etc. that may be attached to the edge or inner wall of the liquid filling port, avoiding leaving dead corners during wiping, and improving wiping efficiency and cleaning effect; moreover, the shape of the protrusion 2 is adapted to the liquid filling port of the battery 500, which can also facilitate the precise alignment between the wiping head 100 and the liquid filling port of the battery 500.

[0054] For example, when the liquid inlet of battery 500 is a cylindrical liquid inlet, protrusion 2 is a cylindrical protrusion that matches the cylindrical liquid inlet; or when the liquid inlet of battery 500 is an inverted frustum-shaped liquid inlet, protrusion 2 is an inverted frustum-shaped protrusion that matches the inverted frustum-shaped liquid inlet, so as to increase the area of ​​direct or indirect contact (through wiping cloth 400) between protrusion 2 and liquid inlet of battery 500, so that wiping cloth 400 is evenly sandwiched between wiping head 100 and liquid inlet of battery 500, ensuring the efficiency of cleaning liquid inlet of battery 500.

[0055] In the above embodiments, see Figure 5By rotating the wiping head 100, the wiping head 100 cleans the residual electrolyte at the filling port of the battery 500 through the flexible wiping cloth 400. Moreover, the shape of the protrusion 2 can be adapted to the filling port of the battery 500, so that the wiping head 100 can effectively contact the filling port of the battery 500 through the wiping cloth 400, thereby improving the cleaning effectiveness of the filling port of the battery 500.

[0056] In some embodiments, the wiping head 100 can be made of metal or non-metallic materials such as hard PEEK (polyetheretherketone), EDPM (ethylene propylene diene monomer rubber), or Teflon to ensure the rigidity and cleaning accuracy of the wiping head 100 and prevent powder from falling off during use; the hardness of the wiping head 100 is A70-A90, which improves the wear resistance and service life of the wiping head 100.

[0057] In one embodiment, see Figures 1 to 9 The wiping head 100 also includes a connecting rod 4, which is connected to the body 1 and used to connect the driving component that drives the wiping head 100 to rotate, so as to ensure the efficiency and stability of the rotation of the wiping head 100.

[0058] In one specific embodiment, see Figures 6 to 9 The connecting rod 4 is detachably connected to the body 1 so that different driving components can be connected through different connecting rods 4, thereby improving the adaptability of the wiping head 100.

[0059] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The protrusion 2 has a top surface 21 and a side surface 22. The top surface 21 is away from the body 1 and is used to cooperate with the bottom wall of the liquid injection port of the battery 500. The side surface 22 surrounds the top surface 21 and forms an inverted frustum-shaped protrusion 2.

[0060] In the above embodiment, the liquid injection port of the battery 500 can be a truncated cone-shaped cavity. The protrusion 2 of the wiping head 100 matches the truncated cone-shaped cavity. That is, the outer diameter of the wiping head 100 simulates the taper of the liquid injection port of the battery 500, so that the wiping head 100 is set with a taper that matches the liquid injection port. The truncated cone-shaped protrusion 2 can fit more closely to the shape of the liquid injection port of the battery 500.

[0061] When the protrusion 2 of the wiping head 100 is embedded into the liquid filling port of the battery 500, the top surface 21 of the protrusion 2 can indirectly contact the bottom wall of the liquid filling port of the battery 500 (through the wiping cloth 400), and the side surface 22 of the protrusion 2 can indirectly contact the side wall of the liquid filling port of the battery 500 (through the wiping cloth 400). The compatibility between the inverted frustum-shaped protrusion 2 and the liquid filling port of the battery 500 allows the wiping head 100 to fully contact and cover the entire inner surface of the liquid filling port of the battery 500 during the wiping process, thereby improving the wiping effect.

[0062] Furthermore, because the side 22 of the protrusion 2 has a certain angle of inclination, the protrusion 2 can generate a certain scraping force during wiping, so as to remove stubborn stains adhering to the inner wall of the electrolyte inlet of the battery 500 and improve the cleaning efficiency of the electrolyte inlet of the battery 500. Moreover, the frustoconical protrusion 2 makes it easier for the wiping head 100 to be inserted and positioned in the electrolyte inlet of the battery 500, improving the efficiency of operation, and the frustoconical shape can improve the versatility of the wiping head 100.

[0063] In the above embodiments, see Figure 1 and Figure 2 The top surface 21 is cross-shaped, and the side surface 22 includes four sub-side surfaces 221, each of which is disposed at the end of the cross-shaped top surface 21.

[0064] In the above embodiment, the cross-shaped top surface 21 improves the stability of the contact between the top surface 21 and the bottom wall of the liquid injection port of the battery 500. When the wiping head 100 applies pressure to the liquid injection port of the battery 500, the cross-shaped top surface 21 can disperse the stress and improve the stability of the overall structure of the wiping head 100 and the battery 500.

[0065] In the above embodiments, see Figure 1 and Figure 2 The four sub-sides 221 are respectively provided at the ends of the cross-shaped top surface 21, which can further enhance the stability and strength of the contact between the wiping head 100 and the liquid injection port of the battery 500, and prevent the wiping head 100 from shifting or being damaged due to excessive local force.

[0066] In the above embodiments, see Figure 1 and Figure 6 The side surface 221 is an arc surface with a gradually decreasing curvature.

[0067] In the above embodiment, the sub-side surface 221 is similar to the cutting edge of a milling cutter, which can generate a certain scraping force during wiping; multiple sub-side surfaces 221 form multiple equally spaced cutting edges similar to the shape of a milling cutter, which can effectively contact the electrolyte crystals inside the filling port of the battery 500 through the wiping cloth 400. The cutting edge formed by the sub-side surface 221 of the wiping head 100 cuts and rubs the crystallized electrolyte, increasing the shearing force between the wiping head 100 and the crystallized electrolyte, which can wipe away the crystallized electrolyte inside the filling port of the battery 500, effectively improving the cleaning effect of wiping.

[0068] In the above embodiments, see Figure 1 and Figure 6 The wiping head 100 also includes a pressing part 3, which is disposed on the wiping surface 11 and used to press the liquid injection port of the wiping cloth 400 to the battery 500.

[0069] In the above embodiment, when the wiping head 100 wipes the electrolyte inlet of the battery 500, it cleans the residual electrolyte in the electrolyte inlet of the battery 500 by rotating the wiping head 100 through the flexible wiping cloth 400, avoiding hard contact between the wiping head 100 and the electrolyte inlet of the battery 500. However, this also causes the wiping cloth 400 between the wiping head 100 and the electrolyte inlet of the battery 500 to tend to rotate. The setting of the pressing part 3 allows the wiping cloth 400 to fit more tightly against the battery electrolyte inlet, increasing the pressure during wiping and ensuring that the wiping cloth 400 maintains close contact with the electrolyte inlet during the wiping process. This prevents the wiping cloth 400 from wrinkling or folding due to rotation, ensuring the consistency and reliability of the wiping effect.

[0070] In some embodiments, see Figure 1 and Figure 2 The pressing part 3 includes a plurality of pressing strips 31, one end of which is connected to the middle of the wiping surface 11, and the other ends of which are evenly distributed on the wiping surface 11; or,

[0071] See Figure 6 and Figure 8 The crimping part 3 includes a plurality of crimping blocks 32, which are distributed around the protrusion 2.

[0072] In the above embodiments, the pressure strip 31 can be elongated, for example, the pressure strip 31 extends radially along the wiping surface 11, that is, one end of multiple pressure strips 31 converges to form a common connection point or connection area, which is located in the middle of the wiping surface 11; the other ends of multiple pressure strips 31 are evenly distributed on the wiping surface 11, so that the distribution of multiple pressure strips 31 on the wiping surface 11 is uniform, and each pressure strip 31 maintains the same distance, ensuring that the wiping cloth 400 can fit more tightly against the liquid injection port of the battery 500.

[0073] In the above embodiment, the pressure block 32 can be square-shaped, and multiple pressure blocks 32 are distributed around the protrusion 2. A stable multi-point pressing structure can be formed by multiple pressure blocks 32, so that the wiping cloth 400 can be more firmly attached to the liquid injection port of the battery 500.

[0074] It is worth noting that the crimping part 3 may include both a crimping strip 31 and a crimping block 32. The radial length of the crimping strip 31 is greater than that of the crimping block 32, which can increase the crimping size of the crimping part 3 in the radial direction. The circumferential width of the crimping block 32 is greater than that of the crimping strip, which can increase the contact force between the wiping head 100 and the liquid injection port of the battery 500 while ensuring the crimping effect.

[0075] See Figures 10 to 12 This application provides a floating wiping device, which includes a rotating mechanism 200, a floating mechanism 300, and the aforementioned wiping head 100;

[0076] The rotating mechanism 200 is connected to the floating mechanism 300, and the wiping head 100 is mounted on the rotating mechanism 200 and used to wipe the battery's filling port.

[0077] In the above embodiments, the rotating mechanism 200 may include a motor, which is connected to the wiping head 100 via a coupling, which simplifies the connection structure between the rotating mechanism 200 and the wiping head 100, shortens the connection length, and ensures the rigidity of the wiping head 100.

[0078] The rotating mechanism 200 can drive the wiping head 100 to rotate and wipe. This dynamic wiping method can more effectively remove stains and residues on the filling port. Moreover, the wiping head 100 can apply pressure evenly during rotation to ensure that the cleaning surface between the wiping head 100 and the filling port of the battery 500 is cleaned evenly.

[0079] See Figure 12 The floating mechanism 300 can drive the rotating mechanism 200 and the wiping head 100 to float together, so that the wiping head 100 can be finely adjusted according to the shape, size and position of the liquid injection port of the battery 500, ensuring that the wiping head 100 and the liquid injection port always maintain proper contact, thereby improving the accuracy and efficiency of wiping.

[0080] In some embodiments, see Figure 11 and Figure 12 The wiping head 100 can move closer to or further away from the battery's filling port in the first direction;

[0081] The floating mechanism 300 includes a slide rail 301 and a sliding plate 302. The rotating mechanism 200 is connected to the sliding plate 302, and the sliding plate 302 and the slide rail 301 slide in a first direction.

[0082] In the above embodiment, when the wiping head 100 approaches the liquid injection port of the battery 500 along the first direction, the wiping head 100 and the liquid injection port of the battery 500 can be matched, so that the wiping cloth 400 is evenly sandwiched between the wiping head 100 and the liquid injection port of the battery 500.

[0083] like Figure 11 and Figure 12 As shown, the first direction is vertical. When the wiping head 100 moves downwards towards the liquid inlet of the battery 500, the wiping cloth 400 can be evenly sandwiched between the wiping head 100 and the liquid inlet of the battery 500, ensuring the accuracy and consistency of the wiping operation.

[0084] In the above embodiment, the rotating mechanism 200 can slide along the slide rail 301 following the sliding plate 302, thereby driving the wiping head 100 to move in the first direction. The cooperation between the slide rail 301 and the sliding plate 302 can ensure the stability and movement accuracy of the wiping head 100, and improve the effect of rotation wiping.

[0085] In some embodiments, see Figure 11 and Figure 12 The floating mechanism 300 includes a positioning plate 303, multiple slide rails 301 are spaced apart on the positioning plate 303 along the second direction, and multiple sliding plates 302 are correspondingly engaged with the multiple slide rails 301 and can correspondingly drive multiple rotating mechanisms 200 to move along the first direction.

[0086] In the above embodiments, the positioning plate 303 can be fixedly set to ensure the stability of the multiple slide rails 301 spaced apart along the second direction; by setting multiple slide rails 301 and corresponding sliding plates 302 to cooperate with each other, the multiple wiping heads 100 on the multiple rotating mechanisms 200 can be used to wipe multiple battery filling ports synchronously, thereby improving wiping efficiency.

[0087] See Figure 10 and Figure 11 Each sliding plate 302 can move independently on the slide rail 301, allowing each wiping head 100 to be individually positioned and wiped for the liquid filling port of each battery 500. This ensures that each wiping head 100 maintains proper contact with the liquid filling port of its corresponding battery 500, thereby achieving a uniform wiping effect and enhancing the flexibility of wiping.

[0088] In addition, the parallel arrangement of multiple slide rails 301 and sliding plates 302 helps to ensure the stability and straightness of the wiping head 100 during movement, reduce errors and mutual interference during wiping, and improve the accuracy and consistency of wiping.

[0089] In one embodiment, a slide rail 301 and a sliding plate 302 constitute a linear guide slider mechanism, such as Figure 10 and Figure 11 As shown, four linear guide slider mechanisms are mounted on the same positioning plate 303, and the linear guide slider mechanisms are positioned by positioning pins, ensuring the center distance and parallelism of the four linear guide slider mechanisms.

[0090] In the above embodiments, see Figure 12 The floating mechanism 300 also includes a guide member 304 and an elastic member 305. The sliding plate 302 has a first connecting part, and the positioning plate 303 has a second connecting part. One of the first connecting part and the second connecting part is connected to the guide member 304, and the other of the first connecting part and the second connecting part is provided with a guide hole through the guide member 304.

[0091] The elastic element 305 is sleeved on the guide element 304 and located between the first connecting part and the second connecting part.

[0092] In the above embodiments, the guide member 304 may include a guide shaft and a guide sleeve, with the guide sleeve sleeved on the guide shaft so that the elastic member 305 moves with the guide sleeve around the outer periphery of the guide sleeve.

[0093] In one embodiment, the first connecting portion of the sliding plate 302 is connected to the guide member 304, and the second connecting portion of the positioning plate 303 is provided with a guide hole through the guide member 304, so that the sliding plate 302 can drive the rotating mechanism 200 and the wiping head 100 to float together.

[0094] When the rotating mechanism 200 drives the wiping head 100 to rotate, the wiping head 100 contacts and rotates with the liquid filling port of the battery 500. Since the elastic element 305 is sleeved on the guide 304 and located between the first connecting part and the second connecting part, the elastic element 305 can ensure that the rotating mechanism 200 and the wiping head 100 float. For example, when the rotating mechanism 200 and the wiping head 100 float upward, the elastic element 305 is compressed; when the rotating mechanism 200 and the wiping head 100 float downward, the elastic element 305 is extended to accommodate batteries of different heights, ensuring effective contact between the wiping head 100 and the liquid filling port of the battery 500, and improving the wiping effect of the wiping head 100 wiping the liquid filling port of the battery 500 through the wiping cloth 400.

[0095] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
