Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0041] The present invention provides a battery cell cylindrical surface cleaning mechanism, which can be used to remove dust from the cylindrical surface 11 of the battery cell 1 during the production process of the battery cell 1; in this embodiment, Figure 1 As shown in the figure, the battery cell 1 is a cylindrical steel shell battery cell, the cylindrical outer surface of the main part of the battery cell 1 (that is, the side surface extending from one end of the battery cell 1 to the other end) is the cylindrical surface 11 of the battery cell 1, and the flat parts at both ends of the battery cell 1 are the end faces 12 of the battery cell 1, and the end faces 12 are perpendicular to the cylindrical surface 11; of course, in addition to the battery cells 1 with the above structure, dust removal and cleaning of the cylindrical surface 11 of other battery cells 1 with similar structures can also be applied, and there is no limitation here.

[0042] like Figure 2 The figure shows a schematic structural diagram of the battery cell cylindrical surface cleaning mechanism, which includes at least one group of cleaning units (one group of cleaning units can be for the cylindrical surface 11 of one battery cell 1 and perform dust removal cleaning. In this embodiment, the battery cell cylindrical surface cleaning mechanism includes five groups of cleaning units, which can be for the cylindrical surfaces 11 of five battery cells 1 and perform dust removal cleaning. In specific applications, the number of cleaning units can also be set according to actual needs). The cleaning unit includes a clamping mechanism 2, a first rotary drive mechanism 3, a dust removal mechanism 4 and a dust suction mechanism 5, wherein:

[0043] The clamping mechanism 2 is provided with a clamping head, which contacts and applies pressure to the end faces 12 at both ends of the battery core 1, thereby clamping the battery core 1 to ensure its stability and positioning accuracy during the processing.

[0044] The first rotation drive mechanism 3 can drive the battery cell 1 to rotate along the axis. Specifically, it can directly act on the battery cell 1 to rotate it along the axis, or it can indirectly act on the battery cell 1 to rotate it along the axis. For example, in this embodiment, the first rotation drive mechanism 3 drives the chuck of the clamping mechanism 2 to rotate, thereby driving the battery cell 1 to rotate along the axis, etc., and there is no limitation here.

[0045] The dust removal mechanism 4 is fixed to the side of the cylindrical surface 11 of the battery cell 1 (the side of the cylindrical surface 11 of the battery cell 1 can be above, below, or on the left or right side of the battery cell 1, etc., and there is no limitation here; in the present embodiment, the dust removal mechanism 4 is fixed above the cylindrical surface 11 of the battery cell 1); the dust removal mechanism 4 can be a brush, a dry cloth, a sponge, a sticky paper, etc., and the dust on the cylindrical surface 11 of the battery cell 1 can be removed by the dust removal mechanism 4 contacting with the cylindrical surface 11 of the battery cell 1; at the same time, the dust removal range of the dust removal mechanism 4 covers the length of the cylindrical surface 11 of the battery cell 1, so that each contact can complete the dust removal and cleaning of the length range of the cylindrical surface 11 of the battery cell 1 at one time.

[0046] The dust suction mechanism 5 can be used to suck away the removed dust.

[0047] When in use, the clamping mechanism 2 first acts on the end faces 12 at both ends of the battery cell 1 to clamp the battery cell 1, and then the first rotation drive mechanism 3 drives the battery cell 1 to rotate along the axis. During the rotation, the dust removal mechanism 4 is in contact with the cylindrical surface 11 of the battery cell 1 to remove dust on the cylindrical surface 11 of the battery cell 1, thereby achieving dust removal and cleaning.

[0048] The battery cell cylindrical surface cleaning mechanism adopting the above structure can realize automatic dust removal and cleaning of the cylindrical surface 11 of the battery cell 1 through the mutual cooperation between the clamping mechanism 2, the first rotary drive mechanism 3, the dust removal mechanism 4 and the dust suction mechanism 5. Compared with the existing technology, it has the following beneficial effects: (1) It improves the cleaning efficiency and can adapt to the growing production capacity demand; (2) It improves the cleaning effect, thereby improving product quality, which is beneficial to the consistency control of battery products; (3) It reduces labor costs, and at the same time reduces the defective product rate, thereby reducing the overall production cost, which is beneficial to the long-term development of the enterprise.

[0049] In some embodiments, as Figure 3 、 Figure 4 、 Figure 5 As shown, the dust removal mechanism 4 includes a roller brush 41 , which contacts the cylindrical surface 11 of the battery cell 1 and can remove dust on the cylindrical surface 11 of the battery cell 1 .

[0050] With the battery cell cylindrical surface cleaning mechanism of the above structure, the roller brush 41 has a highly efficient cleaning ability and a better cleaning effect, and is highly adaptable and gentler, which can reduce the risk of damage to the battery cell 1 and further improve the cleaning effect of the battery cell cylindrical surface cleaning mechanism.

[0051] In some embodiments, as Figure 7 As shown, the roller brush 41 can rotate along the axis, and the rotation direction of the roller brush 41 is opposite to the rotation direction of the battery cell 1, that is: if the battery cell 1 rotates clockwise, the roller brush 41 rotates counterclockwise; if the battery cell 1 rotates counterclockwise, the roller brush 41 rotates clockwise.

[0052] The battery cell cylindrical surface cleaning mechanism with the above structure can, through the reverse rotation of the roller brush 41, achieve the following: (1) Enhanced friction and cleaning effect: Reverse rotation increases the relative speed between the roller brush 41 and the surface of the battery cell 1, thereby enhancing the friction between the two, helping to more effectively loosen and remove dust attached to the cylindrical surface 11 of the battery cell 1. Compared with the same-direction rotation or single-direction contact, reverse rotation can provide a stronger "scraping" effect, resulting in a better cleaning effect; (2) Reduced static electricity accumulation: During the cleaning process, the reverse rotation movement mode is more likely to disrupt the static electricity distribution that has been formed, which can help break the static electricity field and prevent dust from being deposited again on the surface that has just been cleaned. (3) Uniform wear distribution: The self-rotation of the roller brush 41 helps to evenly distribute wear over its entire circumference, preventing rapid wear due to local overuse, which not only extends the service life of the roller brush 41, but also ensures consistent cleaning performance throughout the entire use cycle.

[0053] In some embodiments, the dust removal mechanism 4 includes a second rotation drive mechanism 42, which includes a stepper motor 421, a main synchronous wheel 422, a driven synchronous wheel 423, a synchronous belt 424 and a tensioning wheel 425; the stepper motor 421 is responsible for providing a power source and adjusting the speed and direction by precisely controlling the pulse signal; the main synchronous wheel 422 is fixed to the output shaft of the stepper motor 421 and can rotate under the drive of the stepper motor 421; the main synchronous wheel 422 and the driven synchronous wheel 423 are connected by the synchronous belt 424 , forming a closed power transmission loop, so that the driven synchronous wheel 423 can rotate synchronously with the rotation of the main synchronous wheel 422; the tensioning wheel 425 is located on the outside of the synchronous belt 424 and can be used to adjust the tension of the synchronous belt 424 to ensure that the synchronous belt 424 can maintain appropriate tension when in use, thereby ensuring transmission efficiency and stability; the driven synchronous wheel 423 is fixed on the rotating shaft of the roller brush 41 and is coaxial with the roller brush 41, so that when the driven synchronous wheel 423 rotates, it can also drive the roller brush 41 to rotate.

[0054] With the battery cell cylindrical cleaning mechanism of the above structure, the stepping motor 421, the main synchronous wheel 422, the driven synchronous wheel 423, the synchronous belt 424 and the tensioning wheel 425 together constitute an efficient and stable transmission system, which not only realizes the precise control of the rotation speed of the roller brush 41, but also improves the overall reliability and maintenance convenience of the equipment.

[0055] In some embodiments, when the roller brush 41 contacts the cylindrical surface 11 of the battery cell 1, the amount of hair consumption by the bristles of the roller brush 41 (in this patent, the "hair consumption" specifically refers to the degree to which the bristles of the roller brush 41 are pressed down or deformed) is 2 mm, that is, when the roller brush 41 contacts the cylindrical surface 11 of the battery cell 1, the bristles of the roller brush 41 will be pressed down by 2 mm due to the pressure of the cylindrical surface 11 of the battery cell 1.

[0056] By adopting the battery cell cylindrical surface cleaning mechanism with the above structure, by setting the bristle feeding amount of the roller brush 41 to 2 mm, the bristles of the roller brush 41 can penetrate into the tiny bumps and depressions on the cylindrical surface 11 of the battery cell 1, effectively remove dust and dirt, and achieve effective cleaning without damaging the surface of the battery cell 1.

[0057] In some embodiments, the dust removal mechanism 4 also includes a dust ejecting rod 43 (sometimes also called a dust cleaning rod or a dust scraping rod); the dust ejecting rod 43 is a device for removing dust and impurities attached to cleaning tools (such as brushes, rollers, etc.), which is usually installed in an area close to the cleaning tool, and removes dust accumulated on the cleaning tool through physical contact, ensuring that the cleaning tool can continue to perform cleaning work effectively; in this embodiment, the dust ejecting rod 43 is arranged at the lower left of the roller brush 41, which can remove dust and impurities attached to the roller brush 41; of course, in actual applications, the roller brush 41 can also be arranged in other areas close to the roller brush 41, which is not limited here.

[0058] The battery cell cylindrical surface cleaning mechanism adopts the above structure, and by providing the dust-repelling rod 43, dust and impurities attached to the roller brush 41 can be removed. On the one hand, it helps to maintain the good performance of the roller brush 41 and extend its service life. On the other hand, it can prevent the roller brush 41 from becoming a source of pollution during repeated use, causing dust to be redeposited on the surface of the battery cell 1 and affecting the cleaning effect.

[0059] In some embodiments, when the roller brush 41 contacts the ash spring rod 43, the bristles of the roller brush 41 are pressed down by 2 mm due to the pressure of the ash spring rod 43.

[0060] By adopting the battery cell cylindrical surface cleaning mechanism with the above structure, by setting the bristle feeding amount of the roller brush 41 to 2 mm, the dust ejecting rod 4 can have a better cleaning effect on the roller brush 41 and can more thoroughly remove dust and impurities attached to the roller brush 41.

[0061] In some embodiments, the dust removal mechanism 4 also includes an ion wind rod 44, the air outlet of the ion wind rod 44 faces the roller brush; the ion wind rod 44 is a device specially designed to eliminate static electricity and blow away dust and other tiny particles. It neutralizes the static charge on the surface of the object by generating positive and negative ions, and uses airflow to blow the neutralized dust and impurities away from the surface of the object, thereby achieving an efficient cleaning effect.

[0062] The battery cell cylindrical cleaning mechanism with the above structure is provided with the ion wind rod 44. When dust is difficult to be removed due to static electricity adsorption on the roller brush 41, the positive and negative ions released by the ion wind rod 44 can neutralize the static electricity, thereby reducing the adsorption force of the dust, and can also effectively blow away the loosened dust, making cleaning easier and achieving the best cleaning effect.

[0063] In some embodiments, as Figure 6 、 Figure 7 As shown, the contact position between the roller brush 41 and the cylindrical surface 11 of the battery cell 1 is defined as the first side on the left side of the contact position and the second side on the right side; the ash ejection rod 43 is fixed to the area of the first side close to the contact position, that is, Figure 7 The position of the lower left of the roller brush 41; the dust collection mechanism 5 is arranged above the ash spring rod 43 and on the same side as the ash spring rod 43; the ion wind rod 44 is fixed to the area near the contact position on the second side, that is, Figure 7 The position of the lower right side of the roller brush 41.

[0064] The battery cell cylindrical cleaning mechanism adopts the above structure. By arranging the dust-bouncing rod 43 and the dust suction mechanism 5 on the same side of the roller brush 41, the dust bounced from the roller brush 41 can be better sucked into the dust removal duct. At the same time, the ion wind rod 44 is arranged on the other side. The overall coordination makes the airflow distribution more uniform, and a better dust removal effect can be obtained.

[0065] In some embodiments, the air outlet of the ion wind rod 44 faces the radial direction of the roller brush 41 , that is, the wind direction of the ion wind rod 44 is perpendicular to the rotation axis of the roller brush 41 .

[0066] The battery cylindrical cleaning mechanism with the above structure can maximize the coverage, optimize the airflow direction, enhance the static neutralization effect, and improve the overall cleaning efficiency by setting the air outlet of the ion wind rod 44 to the radial direction of the roller brush 41.

[0067] In some embodiments, as Figure 8 、 Figure 9 、 Figure 10As shown, the clamping mechanism 2 includes a left clamping head 21, a left clamping cylinder 22 and a right clamping head 23, a right clamping cylinder 24; the left clamping head 21 and the right clamping head 23 are arranged opposite to each other, and the left clamping head 21 and the right clamping head 23 are respectively adapted to the end faces 12 at both ends of the battery cell 1; the left clamping head 21 can be driven by the left clamping cylinder 22 to approach or move away from the right clamping head 23, and the right clamping head 23 can be driven by the right clamping cylinder 24 to approach or move away from the left clamping head 21, so that the left clamping head 21 and the right clamping head 23 can move toward each other to clamp the battery cell 1; in this embodiment, since the battery cell cylindrical surface cleaning mechanism includes five groups of cleaning units, by The left clamping heads 21 of the group cleaning units are all arranged on a left clamping plate, and the right clamping heads 23 of each group cleaning units are all arranged on a right clamping plate. Then, the left clamping plate and the right clamping plate are driven to move respectively by the left clamping cylinder 22 and the right clamping cylinder 24. It is possible to simultaneously drive the five left clamping heads 21 to move by one left clamping cylinder 22, and simultaneously drive the five right clamping heads 23 to move by one right clamping cylinder 24. That is, at this time, the five groups of cleaning units share one left clamping cylinder 22 and one right clamping cylinder 24. Of course, each can also be driven separately by one left clamping cylinder 22 and one right clamping cylinder 24, which is not limited here.

[0068] The battery cell cylindrical surface cleaning mechanism adopts the above structure, and the left clamping head 21, the left clamping cylinder 22 and the right clamping head 23, the right clamping cylinder 24 together form an efficient and stable fixing structure. By achieving precise fixation of the battery cell 1, the positioning accuracy is better, the adaptability is strong, and the maintenance is simple.

[0069] In some embodiments, at least one end face 12 of the battery cell 1 is provided with a positioning groove (the positioning groove is usually one or more small grooves of a specific shape, which is mainly used to help accurately locate the position of the battery cell 1 during the production and assembly process to ensure that various operations can be carried out accurately), that is, the end face 12 at the left end of the battery cell 1 can be provided with a positioning groove, or the end face 12 at the right end of the battery cell 1 can be provided with a positioning groove, or the end faces 12 at both ends of the battery cell 1 can be provided with positioning grooves; at the same time, the corresponding end faces 12 on the clamping head of the clamping mechanism 2 A positioning pin adapted to the positioning groove is provided. For example, when the end face 12 at the left end of the battery cell 1 is provided with a positioning groove, a positioning pin adapted to the positioning groove is provided on the left clamp 21 of the clamping mechanism 2. When the end face 12 at the right end of the battery cell 1 is provided with a positioning groove, a positioning pin adapted to the positioning groove is provided on the right clamp 23 of the clamping mechanism 2. When the end faces 12 at both the left and right ends of the battery cell 1 are provided with positioning grooves, positioning pins adapted to the positioning groove are provided on both the left clamp 21 and the right clamp 23 of the clamping mechanism 2.

[0070] The battery cell cylindrical surface cleaning mechanism adopting the above structure can quickly and accurately align the battery cell 1 through the mutual matching between the positioning groove on the end face 12 of the battery cell 1 and the positioning pin on the clamping head of the clamping mechanism 2, thereby improving the positioning accuracy. At the same time, the positioning groove can also provide an additional fixing point to prevent the battery cell 1 from moving during the cleaning process, thereby enhancing stability.

[0071] In some embodiments, a positioning groove is provided on the right end face 11 of the battery cell 1, a positioning pin corresponding to the positioning groove is provided on the right clamp 23, and the right clamp 23 is coaxial with the battery cell 1; the first rotation drive mechanism 3 can drive the right clamp 23 to rotate along the axis; of course, a positioning groove can also be provided on the left end face 11 of the battery cell 1, a positioning pin corresponding to the positioning groove is provided on the left clamp 21, and the left clamp 21 is coaxial with the battery cell 1, and the first rotation drive mechanism 3 can drive the left clamp 21 to rotate along the axis; this direction is only based on the direction in the drawings in this patent, and does not specifically refer to a fixed direction.

[0072] The battery cell cylindrical surface cleaning mechanism adopts the above structure, by setting a positioning groove on one side end face 11 of the battery cell 1, and correspondingly setting a positioning pin adapted to the positioning groove on one side clamp of the clamping mechanism 2, so that the positioning pin can be stuck in the positioning groove, and then combined with the clamping action of the clamps on both sides of the clamping mechanism 2, the battery cell 1 is fixed; then, the clamp on one side provided with the positioning pin is driven to rotate along the axis by the first rotation drive mechanism 3, which can drive the battery cell 1 to rotate along the axis; compared with controlling the rotation of both sides at the same time, it has the following advantages: (1) Single-sided drive can avoid the slight deviation or asynchronous problem that may occur when the two sides are driven synchronously, ensuring that the battery cell 1 maintains a stable center position during the rotation process, which is not only more stable but also has higher positioning accuracy; (2) The overall mechanical structure is simplified, which is convenient for daily inspection, debugging and maintenance, and reduces the manufacturing cost and maintenance difficulty.

[0073] In some embodiments, the first rotation drive mechanism 3 includes a gear 31 and a servo motor 32; the right chuck 23 is fixedly connected to the gear 31, and the right chuck 23 is coaxial with the gear 31; the servo motor 32 can drive the gear 31 to rotate along the axis; in this embodiment, since the battery cell cylindrical cleaning mechanism includes five groups of cleaning units, the right chuck 23 of each cleaning unit is fixedly connected to a gear 31. When the five gears 31 are engaged to form a gear set, the five gears 31 can be driven to rotate synchronously by a servo motor 32. That is, at this time, the servo motors 32 of the five groups of cleaning units share one. Of course, each of them can also be driven separately by a servo motor 32, which is not limited here.

[0074] The battery cell cylindrical surface cleaning mechanism adopts the above structure, and the servo motor 32 drives the gear 31 to rotate along the axis, which can drive the right clamp 23 to rotate along the axis, and then drive the battery cell 1 to rotate along the axis. This transmission method is more precise, reliable and efficient, and can enhance the overall performance and durability of the battery cell cylindrical surface cleaning mechanism. Moreover, when the number of the cleaning units is multiple groups, a servo motor 32 can simultaneously drive multiple gears 31 to rotate synchronously, that is, drive multiple battery cells 1 to rotate along the axis, which is more energy-saving and efficient, and has better applicability.

[0075] In some embodiments, battery cell rollers 6 are provided on both sides of the bottom of the cylindrical surface 11 of the battery cell 1 . The battery cell rollers 6 can stably support the battery cell 1 and rotate synchronously with the battery cell 1 as it rotates along the axis.

[0076] The battery cell cylindrical surface cleaning mechanism adopts the above structure, by arranging battery cell rollers 6 on both sides of the bottom of the cylindrical surface 11 of the battery cell 1, and providing additional support points through the battery cell rollers 6, it helps to improve the positioning accuracy and stability of the battery cell 1. The battery cell rotation is smoothly guided by the battery cell rollers 6, which can avoid scratches or other physical damages that may be caused by hard contact and reduce friction damage.

[0077] In some embodiments, the battery cell cylindrical surface cleaning mechanism further includes a lifting mechanism 7 , and the lifting mechanism 7 can control the dust removal mechanism 4 and the dust suction mechanism 5 to move up and down.

[0078] The battery cell cylindrical surface cleaning mechanism adopts the above structure, and the lifting mechanism 7 is set to control the up and down lifting movement of the dust removal mechanism 4 and the dust suction mechanism 5. On the one hand, the position of the dust removal mechanism 4 and the dust suction mechanism 5 can be adjusted according to the diameter of the battery cell 1, so that it is suitable for dust removal and cleaning of battery cells 1 of different specifications; on the other hand, it can make it more convenient to replace the parts of the dust removal mechanism 4 and the dust suction mechanism 5, thereby improving the flexibility of the battery cell cylindrical surface cleaning mechanism.

[0079] In some embodiments, as Figure 11 As shown, the dust removal pipe of the dust suction mechanism 5 covers the length of the cylindrical surface 11 of the battery cell 1, and the dust removal pipe of the dust suction mechanism 5 is provided with a plurality of sub-grids 51, so that the wind speed of the dust suction mechanism 5 is consistent along the entire length direction of the cylindrical surface 11 of the battery cell 1.

[0080] The battery cell cylindrical surface cleaning mechanism with the above structure is configured to provide a plurality of sub-grids 51 in the dust removal pipe of the dust suction mechanism 5, so that the wind speed of the dust suction mechanism 5 is consistent along the entire length direction of the cylindrical surface 11 of the battery cell 1, thereby providing a consistent dust suction effect throughout the entire length range of the battery cell 1, to ensure that dust can be effectively removed without causing local insufficient cleaning.

[0081] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Any equivalent changes made based on the shape, structure and principle of the present invention should be included in the scope of protection of the present invention.
