[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0051] Among the related technologies, with the introduction of the "dual carbon" policy, the new energy industry has developed rapidly, among which lithium-ion batteries and sodium-ion batteries are widely used in various industries. Among them, lithium-ion batteries and sodium-ion batteries are divided into full-pole batteries and non-full-pole batteries.

[0052] Lithium-ion and sodium-ion full-tab batteries can be divided into compact full-tab and channel-type full-tab batteries. Both types of tab batteries require the battery tabs to be welded to the current collector or steel shell during the production and assembly process. However, due to the extension or winding error of the pole piece after rolling, the end of the full tab will be less neat, which may cause poor welding problems when welding the tab and the current collector or steel shell.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, in order to solve the above technical problems, an embodiment of the present application provides a full-pole-tab battery, the full-pole-tab battery comprising a full-pole-tab winding core 100 and a current collecting plate 200, the full-pole-tab winding core 100 having a winding axis 120 and a pole tab 110, the pole tab 110 comprising a positive pole tab 110 and a negative pole tab 110; wherein the positive pole tab 110 and / or the negative pole tab 110 are arranged obliquely toward the winding axis 120 of the full-pole-tab winding core 100; a collecting plate 200 is arranged at one end of the full-pole-tab winding core 100 where the pole tab 110 is arranged obliquely toward the winding axis 120 of the full-pole-tab winding core 100. The flow plate 200 has an axis of the current collecting plate 200 and a plurality of welding grooves 210. The plurality of welding grooves 210 are located at one end of the current collecting plate 200 away from the full-pole lug winding core 100. The plurality of welding grooves 210 are arranged at intervals along the circumferential direction of the axis of the current collecting plate 200. The welding grooves 210 extend along a preset direction, and the bottom of the welding groove 210 is welded to the corresponding pole lug 110. In the preset direction, the bottom of the welding groove 210 protrudes from the end of the current collecting plate 200 close to the full-pole lug winding core 100 and the height gradually increases, and the preset direction is the direction away from the axis of the current collecting plate 200.

[0054] In these embodiments, the present application provides an improved full-ear battery design and related components, which mainly solves the problem of uneven ends of the ear 110 and short circuit caused by metal debris due to the extension or winding error after the pole piece is rolled during the production process of the traditional full-ear battery, thereby affecting the quality of welding between the ear 110 and the collector or steel shell. Obviously, by making the positive pole ear 110 and / or the negative pole ear 110 tilted toward the winding axis 120, and providing a welding groove 210 with a specific structure on the collector plate 200, this design not only improves the welding quality, but also increases the contact area between the ear 110 and the collector plate 200, which helps to reduce the internal resistance of the battery and improve the battery performance.

[0055] It should be noted that the full-electrode winding core 100 includes a positive electrode sheet, a separator, a negative electrode sheet, a positive current collector 200, and a negative current collector 200. The positive electrode sheet, the separator, and the negative electrode sheet are wound in a sandwich structure. The upper and lower sides of the full-electrode winding core 100 are respectively the positive electrode tab 110 and the negative electrode tab 110. The middle of the winding core is a central hole. The negative electrode tab 110 is connected to the steel shell through the negative current collector 200, and the steel shell is negatively charged. The positive electrode tab 110 is connected to the positive electrode column through the positive current collector 200, and the positive electrode column is positively charged. The positive current collector 200 is welded to the positive electrode tab 110 at the top of the winding core, and the negative current collector 200 is welded to the negative electrode tab 110 at the bottom of the full-electrode winding core 100.

[0056] Specifically, the key point of this design is: the skewed setting of the pole tab 110, that is, the pole tab 110 and / or the negative pole tab 110 is not directly perpendicular to the winding core, but has a certain inclination angle, and the pole tab 110 is biased toward the axis of the full-pole tab winding core 100, which helps to compensate for the position deviation of the pole tab 110 caused by errors in the manufacturing process, improve the contact rate between the pole tab 110 and the current collector or steel shell, and ensure better alignment and welding effects.

[0057] In other words, the present application adopts the method of pre-treating the tabs 110 before welding the current collecting plate 200, applying a force to the tabs 110 along the radial direction of the full tab winding core 100, so that the tabs 110 are slightly tilted inward along the radial direction of the full tab winding core 100. When the tabs 110 of the full tab winding core 100 are welded to the current collecting plate 200, it is possible to avoid the poor welding of individual collapsed tabs 110, increase the welding area between the tabs 110 and the current collecting plate 200, and reduce the internal resistance of the battery.

[0058] With respect to the design of the collector plate 200, the welding groove 210 on the collector plate 200 is mainly to gradually increase in height along the direction away from the axis of the collector plate 200. This design can better adapt to the skewed setting of the pole lug 110, ensuring good welding even when there is a slight position deviation. In addition, such a design can also increase the effective contact area between the pole lug 110 and the collector plate 200, thereby reducing the contact resistance and improving the overall performance of the battery. In short, the pole lug 110 is tilted toward the axis of the full-pole lug winding core 100, and the bottom protrusion height of the welding groove 210 is set, that is, the bottom of the welding groove 210 on the collector plate 200 is gradually lowered in the direction close to the full-pole lug winding core 100, and then the bottom of the pole lug 110 and the welding groove 210 form an inclined surface match, which is conducive to maintaining the tilted state of the pole lug 110, and can increase the contact area between the collector plate 200 and the corresponding pole lug 110.

[0059] For example, in this embodiment, the inclination angle of the bottom of the welding groove 210 is the same as the inclination angle of the tab 110 . Of course, in other embodiments, the inclination angle of the bottom of the welding groove 210 is smaller than the inclination angle of the tab 110 .

[0060] For example, the angle between the axis of the tab 110 and the full tab winding core 100 is 10°. Of course, in other embodiments, the angle between the axis of the tab 110 and the full tab winding core 100 is 20°, 30°, 40°, etc. Optionally, the angle between the axis of the tab 110 and the full tab winding core 100 is less than 90°.

[0061] Therefore, this innovative design is of great significance for improving the manufacturing quality and performance of full-tab batteries, especially in modern battery applications that pursue higher energy density and longer service life. In addition, the design has a wide range of applications and is suitable for various devices using lithium-ion or sodium-ion batteries, such as electric vehicles, energy storage systems, etc.

[0062] like Figure 2 As shown, in some embodiments, the positive electrode tab 110 and the negative electrode tab 110 are both tilted toward the winding axis 120 of the full-tab winding core 100 .

[0063] In these embodiments, when the positive electrode tab 110 and the negative electrode tab 110 are both arranged obliquely toward the winding axis 120 of the full tab winding core 100, that is, the positive electrode tab 110 and the negative electrode tab 110 are both arranged obliquely toward the axis of the full tab winding core 100, this design can bring the following specific beneficial effects:

[0064] The skewed setting of the positive pole tab 110 and the negative pole tab 110 can better compensate for the extension or error of the pole piece during the rolling and winding process, so that the pole tab 110 is more neat and has higher alignment accuracy during welding. Welding uniformity: Due to the improved neatness of the pole tab 110, it can be more evenly distributed in the welding groove 210 during welding, reducing the risk of local poor welding and improving the consistency and reliability of welding. The skewed pole tab 110 is more matched with the shape of the welding groove 210 on the current collecting plate 200, and welding can be achieved at more contact points, thereby increasing the welding area. A larger welding area means a stronger mechanical connection, which enhances the bonding force between the pole tab 110 and the current collecting plate 200 and reduces the connection failure caused by mechanical stress. The increase in welding area and more uniform welding distribution can significantly reduce contact resistance and improve the efficiency of current conduction. Low contact resistance helps to reduce the heat generation of welding points, improve the thermal stability of the battery in high-power applications, and extend the service life of the battery.

[0065] The deflection angle of the tab 110 and the design of the welding groove 210 can be adjusted according to different battery capacities and application requirements to achieve optimal performance and reliability. In short, the positive tab 110 and the negative tab 110 are both tilted toward the winding axis 120 of the full tab winding core 100, which can significantly improve the welding quality, mechanical connection strength and electrochemical performance of the battery, simplify the production process, improve the yield rate, and provide strong support for the efficient production and wide application of the battery.

[0066] In some embodiments, the bottom thicknesses of the plurality of welding grooves 210 are the same.

[0067] In these embodiments, it should be noted that the welding grooves 210 are formed by the recessed areas of the current collecting plate 200, and the groove bottoms of the plurality of welding grooves 210 have the same thickness. This design can bring the following specific beneficial effects:

[0068] The same groove bottom thickness means that the depth of each welding groove 210 is consistent, which helps to form a uniform weld during the welding process and ensure the consistency of welding quality. Uniform welding depth can reduce defects caused by inconsistent welding depth, such as cold welding and welding penetration, and improve the reliability and stability of welding.

[0069] The design of the same groove bottom thickness can simplify the welding process. The welding of all welding grooves 210 can be completed using the same welding parameters (such as current, time and temperature), reducing the complexity of process adjustment.

[0070] Standardized welding process can improve production efficiency, shorten production cycle and reduce production cost. In addition, the same thickness of the bottom of welding groove 210 can ensure uniform stress distribution of welding points, avoid local stress concentration and improve the mechanical strength of welding points. Uniform welding points can better withstand mechanical vibration and thermal cycle, and improve the durability and reliability of batteries under various working conditions.

[0071] Furthermore, the uniform thickness of the bottom of the welding groove 210 can ensure uniform heat distribution during welding, avoid local overheating, and reduce thermal damage to the welding area. Uniform heat distribution helps to improve the thermal stability of the battery and reduce performance degradation and safety hazards caused by local overheating.

[0072] In addition, uniform welding points can reduce contact resistance and improve the efficiency of current conduction, thereby improving the electrochemical performance of the battery.

[0073] like Figure 3 As shown, in some embodiments, the current collecting plate 200 is provided with a plurality of through holes 220 , and the through holes 220 are extended in a direction away from or close to the full-tab winding core 100 .

[0074] In these embodiments, the current collecting plate 200 is provided with a plurality of through holes 220 , and the through holes 220 are extended in a direction away from or close to the full-tab winding core 100 to achieve liquid injection.

[0075] Furthermore, the through hole 220 can serve as a heat conduction path to help quickly conduct the heat generated inside the battery and improve the heat dissipation performance of the battery, which is particularly important in high-power applications, and can prevent the battery from overheating and improve the thermal stability and safety of the battery.

[0076] The through hole 220 helps to form a more uniform temperature field, reduce local overheating, and extend the service life of the battery. The design of the through hole 220 can reduce the material usage of the collector plate 200, thereby reducing the weight of the entire battery. This is particularly important for applications such as portable devices and electric vehicles, which can improve energy efficiency and endurance.

[0077] It should be noted that the number, position and size of the through holes 220 can be adjusted according to different battery capacities and application requirements to achieve optimal performance and reliability.

[0078] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the present application also provides a pretreatment device for the pole lug 110, the pretreatment device for the pole lug 110 includes a pole lug prostration assembly 300, the pole lug prostration assembly 300 includes a plurality of scrapers 390 and a first driving member, the plurality of scrapers 390 are evenly spaced around a set axis, the first driving member is connected to the plurality of scrapers 390, the first driving member can drive the plurality of scrapers 390 to move radially along the circular distribution line where the plurality of scrapers 390 are located, so that the plurality of scrapers 390 can approach or move away from each other, thereby utilizing the radial movement of the scrapers 390 on the circular distribution line to drive the pole lug 110 to tilt toward the axis of the full pole lug winding core 100.

[0079] In these embodiments, the design of the tab 110 pretreatment device provides an effective solution for ensuring the uniformity and correct deflection of the tab 110 during the production process of a full-tab battery, thereby improving welding quality and battery performance.

[0080] Through the radial movement of multiple scrapers 390, the deflection angle of the tabs 110 can be accurately controlled to ensure that all tabs 110 are tilted toward the axis of the full-tab winding core 100, thereby improving the uniformity of the tabs 110. This mechanical control method can reduce the error caused by manual operation and ensure that each tab 110 can achieve the expected deflection angle.

[0081] In other words, improving the neatness of the tabs 110 can significantly improve the alignment accuracy during welding, reduce the occurrence of poor welding, and improve the success rate and quality of welding. The neat tabs 110 can be more evenly distributed in the welding grooves 210, reducing the risk of local poor welding and ensuring the uniformity and reliability of the welding points.

[0082] The first driving member can automatically control the movement of the plurality of scrapers 390 to achieve automatic lodging of the tabs 110, reduce manual intervention, and improve production efficiency. The pretreatment device can achieve a standardized tab 110 treatment process, reduce the complexity of process adjustment, and improve production consistency and stability.

[0083] Of course, in other embodiments, each scraper 390 is connected to a first driving member, which can also drive the scraper 390 to move radially along the circular distribution line. For example, the first driving member is a telescopic rod, such as an electric telescopic rod, a hydraulic cylinder or a pneumatic cylinder.

[0084] It should be noted that the plurality of scrapers 390 are located on the same circular distribution line, and a receiving groove is formed between the plurality of scrapers 390. In the initial state, the plurality of scrapers 390 are away from each other, and at this time, the slot opening area of ​​the receiving groove is larger than the outer diameter of the full tab winding core 100, so that the full tab winding core 100 can enter and exit the receiving groove.

[0085] In the working state, the first driving member drives the plurality of scrapers 390 to move radially, thereby driving the tabs 110 in the receiving groove to bend and deflect toward the axis of the full tab winding core 100. After the bending is completed, the first driving member drives the scrapers 390 to reset, so that the full tab winding core 100 can be easily taken out.

[0086] Obviously, during this working process, the full-tab core 100 can be put in and out of the receiving slot by a robotic arm, and the full-tab core 100 can also be manually taken and operated.

[0087] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the first driving member includes a driving wheel 340, a wheel seat 360, a plurality of guide posts 380, a plurality of push-pull rods 370 and a driving portion 320, the driving wheel 340 and the wheel seat 360 are rotatably connected, the axis of the driving wheel 340 coincides with the set axis, the driving wheel 340 has a plurality of guide grooves 341, and the plurality of guide grooves 341 are evenly spaced along the circumference of the driving wheel 340; wherein the extension direction of the guide grooves 341 intersects with the radial direction of the driving wheel 340; the guide posts 380 are inserted into the corresponding guide grooves 341, and the guide posts 380 and the guide grooves 341 slide Dynamic cooperation; multiple push-pull rods 370 and multiple guide columns 380 are arranged in a one-to-one correspondence, multiple push-pull rods 370 and multiple scrapers 390 are arranged in a one-to-one correspondence, the push-pull rods 370 extend radially along the driving wheel 340, one end of the push-pull rod 370 is connected to the corresponding guide column 380, the other end of the push-pull rod 370 is connected to the corresponding scraper 390, and the push-pull rod 370 is slidably connected to the wheel seat 360, so that the push-pull rod 370 can move radially along the driving wheel 340; the driving part 320 is connected to the driving wheel 340, and the driving part 320 is used to drive the above-mentioned driving wheel 340 to rotate.

[0088] In these embodiments, the design of the tab 110 pretreatment device achieves automatic lodging of the tab 110 through a precise mechanical structure, ensuring that the tab 110 can be accurately tilted toward the axis of the full-tab winding core 100 .

[0089] The driving wheel 340 and the wheel seat 360 are connected by a bearing or other rotating connection method to ensure that the driving wheel 340 can rotate freely around its axis. The axis of the driving wheel 340 coincides with the set axis, ensuring that the rotation of the driving wheel 340 can accurately control the radial movement of the plurality of scrapers 390.

[0090] The driving wheel 340 is provided with a plurality of guide grooves 341, which are evenly spaced along the circumference of the driving wheel 340, and the extension direction of the guide grooves 341 intersects the radial direction of the driving wheel 340. Each guide post 380 is inserted into the corresponding guide groove 341 and slidably cooperates with the guide groove 341. When the driving wheel 340 rotates, the guide post 380 slides in the guide groove 341, thereby achieving radial movement.

[0091] Each push-pull rod 370 is provided corresponding to a guide column 380 and a scraper 390, and the push-pull rod 370 extends in the radial direction of the driving wheel 340. One end of the push-pull rod 370 is connected to the corresponding guide column 380, and the other end is connected to the corresponding scraper 390. The push-pull rod 370 is slidably connected to the wheel seat 360 to ensure that the push-pull rod 370 can move freely in the radial direction of the driving wheel 340. Exemplarily, the pull rod is slidably connected to the wheel seat 360 through a slide rail, and the slide rail is provided to extend in the radial direction of the rotating wheel.

[0092] The driving part 320 is connected to the driving wheel 340 and is used to drive the driving wheel 340 to rotate. The driving part 320 can be a motor, a cylinder or other driving device, and the radial movement of the scraper 390 can be precisely controlled by precisely controlling the rotation angle of the driving wheel 340.

[0093] Obviously, by rotating the driving wheel 340, the sliding distance of the guide column 380 in the guide groove 341 can be accurately controlled, thereby accurately controlling the radial movement distance of the scraper 390, ensuring that the tab 110 can accurately tilt toward the axis of the full tab winding core 100. The movement distance and direction of all scrapers 390 are consistent, ensuring that the deflection angles of all tabs 110 are consistent, and improving the neatness of the tabs 110. Through the control of the driving unit 320, the automatic lodging of the tab 110 can be achieved, reducing manual intervention and improving production efficiency. Automated operation can achieve continuous production and improve the automation level and production speed of the production line.

[0094] This tab 110 pretreatment device realizes the automatic lodging of the tab 110 through precise mechanical structure and automated control, significantly improves the neatness and welding quality of the tab 110, simplifies the production process, optimizes battery performance, and provides strong support for the efficient production and wide application of full-tab batteries.

[0095] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the driving part 320 includes a driving gear 350 and a driving motor, the main shaft of the driving motor is transmission-connected to the driving gear 350, the driving wheel 340 is a driven gear, and the driving gear 350 is meshed with the driven gear.

[0096] In these embodiments, the design of the tab 110 pre-processing device uses a gear transmission system to achieve precise control of the driving wheel 340 , ensuring that the tab 110 can be accurately tilted toward the axis of the full-tab winding core 100 .

[0097] The main shaft of the driving motor is connected to the driving gear 350 through a coupling or other transmission components to ensure that the rotation of the motor can be directly transmitted to the driving gear 350. The driving motor can be accurately controlled by the control system, and the driving gear 350 can be accurately controlled by adjusting the speed and rotation angle of the motor.

[0098] The driving gear 350 is connected to the main shaft of the driving motor to ensure that the rotation of the motor can be transmitted to the driving gear 350. The driving gear 350 is meshed with the driven gear (i.e., the driving wheel 340), and the rotational motion is transmitted to the driving wheel 340 through the meshing transmission between the gears. The driven gear is rotatably connected to the wheel seat 360 to ensure that the driven gear can rotate freely around its axis. A plurality of guide grooves 341 are provided on the driven gear, and these guide grooves 341 are evenly spaced along the circumference of the driven gear, and the extension direction of the guide grooves 341 intersects with the radial direction of the driven gear. Each guide post 380 is inserted into the corresponding guide groove 341 and slidably cooperates with the guide groove 341. When the driven gear rotates, the guide post 380 will slide in the guide groove 341, thereby realizing radial movement. Each push-pull rod 370 is correspondingly arranged with a guide post 380 and a scraper 390, and the push-pull rod 370 extends in the radial direction of the driven gear. One end of the push-pull rod 370 is connected to the corresponding guide column 380, and the other end is connected to the corresponding scraper 390. The push-pull rod 370 is slidably connected to the wheel seat 360 to ensure that the push-pull rod 370 can move freely along the radial direction of the driven gear.

[0099] Obviously, by precisely controlling the driving motor, the driving gear 350 can be precisely rotated, thereby precisely controlling the rotation angle of the driven gear. This ensures that the sliding distance and direction of the guide column 380 in the guide groove 341 are consistent, thereby precisely controlling the radial movement of the scraper 390. In addition, the moving distance and direction of all scrapers 390 are consistent, ensuring that the deflection angles of all tabs 110 are consistent, thereby improving the neatness of the tabs 110.

[0100] Furthermore, the gear transmission has the characteristics of high precision and high efficiency, which can ensure that the rotation angle and speed of the driven gear are completely synchronized with the driving gear 350, thereby reducing transmission errors.

[0101] like Figure 7 and Figure 8 As shown, in some embodiments, the scraper 390 extends along the circumference of the driving wheel 340;

[0102] The included angle between the extension direction of the guide groove 341 and the radial direction of the driving wheel 340 gradually increases in the direction away from the axis of the driving wheel 340 .

[0103] This design further improves the performance and reliability of the tab 110 pretreatment device by optimizing the structure of the guide groove 341 and the scraper 390 .

[0104] The scraper 390 extends along the circumference of the driving wheel 340, which means that the scraper 390 occupies a certain arc length in the circumferential direction of the driving wheel 340. The circumferential extension design of the scraper 390 can provide a larger contact area.

[0105] Exemplarily, the scraper 390 is configured as an arc-shaped plate. Of course, in other embodiments, the scraper 390 can also be configured as a trapezoidal plate, etc.

[0106] The angle between the extension direction of the guide groove 341 and the radial direction of the driving wheel 340 gradually increases in the direction away from the axis of the driving wheel 340. This design can make the sliding path of the guide column 380 in the guide groove 341 present a gradual change, thereby achieving smooth radial movement of the push-pull rod 370.

[0107] For example, the guide groove 341 is configured as an arc groove. Of course, in other embodiments, the guide groove 341 can also be configured as an inclined groove.

[0108] Obviously, the angle of the guide groove 341 gradually increases in the direction away from the axis of the driving wheel 340, so that the sliding path of the guide column 380 in the guide groove 341 presents a gradual change. This design can ensure that the radial movement of the push-pull rod 370 is smoother and reduce sudden displacement and impact. Smooth radial movement can reduce the jitter of the push-pull rod 370 and the scraper 390 during movement, and improve the stability and reliability of the entire system. The circumferential extension design of the scraper 390 and the gradual change design of the guide groove 341 can ensure that the movement distance and direction of all scrapers 390 are consistent, thereby achieving uniform lodging of the pole lug 110. The neatness of the pole lug 110 is further improved, ensuring that all pole lugs 110 can accurately tilt toward the axis of the full pole lug winding core 100, thereby improving the alignment accuracy during welding.

[0109] like Figure 4 As shown, in some embodiments, the tab 110 pretreatment device further includes a conveying assembly 500, which is used to convey the full tab winding core 100 to move along a first preset path, the first preset path having a pretreatment station, and the axis of the full tab winding core 100 located at the pretreatment station coincides with the set axis;

[0110] The tab lodging assembly 300 also includes a mounting seat 330 and a second driving member 310, wherein the mounting seat 330 is connected to the first driving member, and the second driving member 310 is connected to the mounting seat 330, and the second driving member 310 is used to drive the mounting seat 330 to move along a set axis so that the tab 110 of the full tab winding core 100 located at the pre-processing station can enter and exit the receiving groove formed by multiple scrapers 390.

[0111] In these embodiments, the tab 110 pretreatment device achieves accurate transportation of the full tab winding core 100 and automatic lodging of the tab 110 by adding a conveying assembly 500 and improving the design of the tab lodging assembly 300 .

[0112] The conveying assembly 500 is used to convey the full-tab winding core 100 to move along the first preset path. The first preset path has a pre-processing station, and the axis of the full-tab winding core 100 located at the pre-processing station coincides with the set axis. It is ensured that when the full-tab winding core 100 enters the pre-processing station, its axis is accurately aligned with the set axis, providing conditions for the subsequent tab 110 lodging operation.

[0113] The mounting seat 330 is connected to the first driving member, and is used to fix and support the plurality of scrapers 390. The second driving member 310 is connected to the mounting seat 330, and is used to drive the mounting seat 330 to move along the set axis. The receiving groove formed by the plurality of scrapers 390 is used to receive the tabs 110 of the full tab winding core 100. The second driving member 310 drives the mounting seat 330 to move along the set axis, so that the tabs 110 of the full tab winding core 100 located at the pre-treatment station can enter and exit the receiving groove, and realize the automatic lodging of the tabs 110.

[0114] Obviously, the conveying assembly 500 ensures that the axis of the full-tab core 100 is precisely aligned with the set axis when entering the pretreatment station, providing an accurate position for the subsequent tab 110 lodging operation. Each time the full-tab core 100 enters the pretreatment station, it can maintain a consistent alignment state, ensuring that each tab 110 can be accurately lodged. The conveying assembly 500 can automatically convey the full-tab core 100 to move along the first preset path, reducing manual intervention and improving production efficiency. The second drive member 310 drives the mounting seat 330 to move along the set axis, so that the tab 110 can automatically enter and exit the accommodating groove, realizing the automatic lodging of the tab 110.

[0115] like Figure 4 As shown, in some embodiments, the set axis is vertically arranged, the first preset path is located in a horizontal plane, the conveying assembly 500 includes a conveyor belt 520 and a side plate 510, the conveying direction of the conveyor belt 520 is the extension direction of the first preset path, and side plates 510 are respectively arranged on both sides of the conveyor belt 520, and a pair of the side plates 510 are used to prevent the full-ear winding core 100 from tipping over laterally.

[0116] In these embodiments, the design of the tab 110 pre-processing device ensures that the full tab winding core 100 maintains a precise position and posture during the conveying and processing process by optimizing the conveying assembly 500 and the tab prostrating assembly 300 .

[0117] The axis is set vertically to ensure that the axis of the full-ear core 100 is precisely aligned with the set axis when entering the pretreatment station, that is, the full-ear core 100 is placed vertically. The first preset path is located in the horizontal plane, and the full-ear core 100 is transported to the pretreatment station along this path. The conveying direction of the conveyor belt 520 is the extension direction of the first preset path, which is responsible for transporting the full-ear core 100 from the entrance to the pretreatment station. Side panels 510 are respectively provided on both sides of the conveyor belt 520. The function of the side panels 510 is to prevent the full-ear core 100 from tipping over laterally during transportation, and to ensure that it moves stably along the first preset path.

[0118] Illustratively, the distance between the pair of side plates 510 is slightly larger than the outer diameter of the full-tab winding core 100 , so as to provide support when the full-tab winding core 100 is tilted.

[0119] like Figure 4 and Fig. 9 As shown, in some embodiments, the tab 110 pretreatment device also includes a clamping assembly 400, the clamping assembly 400 includes a pair of clamping members 410 and a third driving member, the pair of clamping members 410 are respectively located on both sides of the pretreatment station, the pair of clamping members 410 are oppositely arranged, and there is an opposing direction between the pair of clamping members 410, the opposing direction is perpendicular to the set axis, the opposing direction intersects with the first preset path, the third driving member is connected to the pair of clamping members 410, and the third driving member is used to drive the pair of clamping members 410 to approach or move away from each other along the opposing direction to clamp or release the bottom and / or middle of the full tab core 100.

[0120] In these embodiments, the tab 110 pretreatment device further improves the stability and control accuracy of the full tab winding core 100 by adding a clamping assembly 400, thereby ensuring a smooth lodging process of the tab 110.

[0121] A pair of clamping members 410 are respectively located on both sides of the pre-processing station and are arranged oppositely, and the opposite direction is perpendicular to the set axis and intersects with the first preset path. The third driving member is connected to the pair of clamping members 410, and is used to drive the clamping members 410 to move closer to or away from each other along the opposite direction to clamp or release the bottom and / or middle of the full-tab winding core 100.

[0122] Obviously, when the full-tab winding core 100 arrives at the pre-processing station, the third driving member drives the clamping member 410 to approach and clamp the full-tab winding core 100 to ensure that it remains stable during the falling process of the tab 110 to prevent position deviation caused by vibration or external force. The opposite direction of the clamping member 410 is perpendicular to the set axis, ensuring that the full-tab winding core 100 remains precisely aligned with the set axis in the clamped state.

[0123] By arranging the opposing direction and the set axis perpendicularly, the opposing direction intersects with the first preset path, so that a pair of clamps 410 can be driven away to move out of the first preset path, thereby avoiding interference with the movement of the full-tab winding core 100.

[0124] Illustratively, the opposing direction and the first preset path are located at a portion of the pre-processing station that is arranged vertically.

[0125] In some embodiments, the first preset path is set to be U-shaped, thereby reducing the occupied space of the entire device.

[0126] like Figure 6 As shown, in some embodiments, the mounting seat 330 passes through the limiting hole 331, and the limiting hole 331 is coaxially arranged with the set axis, wherein the movable setting of the mounting seat 330 enables part of the full-pole lug winding core 100 to enter and exit the limiting hole 331, and the full-pole lug winding core 100 and the limiting hole 331 are clearance-matched.

[0127] In these embodiments, the tab 110 pretreatment device further improves the positioning accuracy and stability of the full tab winding core 100 by adding the design of the limiting hole 331, thereby ensuring the smooth lodging process of the tab 110.

[0128] The limiting hole 331 is coaxially arranged with the set axis. The design of the limiting hole 331 ensures that the axis of the full-tab winding core 100 is precisely aligned with the set axis when entering the pretreatment station. There is a clearance fit between the limiting hole 331 and the full-tab winding core 100, allowing the full-tab winding core 100 to move freely axially in the limiting hole 331, while ensuring the precise alignment of its axis.

[0129] Obviously, the design of the limiting hole 331 ensures that the axis of the full-tab winding core 100 is precisely aligned with the set axis when entering the pretreatment station, providing an accurate position for the subsequent pole tab 110 lodging operation. The clearance fit between the limiting hole 331 and the full-tab winding core 100 allows free movement, but ensures the precise alignment of the axis, which can provide lateral support for the full-tab winding core 100, improve positioning accuracy, and enable the pole tab 110 to enter the receiving groove. In addition, the design of the limiting hole 331 can prevent the full-tab winding core 100 from lateral or longitudinal displacement when entering the pretreatment station, ensuring the stability of its position and posture.

[0130] like Fig. 9As shown, in some embodiments, the clamping assembly 400 also includes a position sensor 420 and a controller, the position sensor 420 and the controller are electrically connected, the controller is electrically connected to the third drive member and / or the second drive member 310, the position sensor 420 is used to detect whether there is a full-ear winding core 100 in the pre-treatment station, and the controller is used to receive the signal of the position sensor 420 and control the action of the third drive member and / or the second drive member 310.

[0131] For example, cylindrical lithium-ion batteries can be divided into compact full-tab batteries and channel-type full-tab batteries.

[0132] After the cylindrical channel-type full-tab winding is completed, the full-tab winding core 100 is placed in the pretreatment station, and the position sensor 420 detects the full-tab winding core 100, and the clamping assembly 400 tightens and fixes the full-tab winding core 100, and the mounting seat 330 descends at the same time. When the scraper 390 overlaps the tab 110 by 0.1-0.5mm, the scraper 390 starts to rotate, applying a force along the radial direction of the full-tab winding core 100 to the tab 110. The tab 110 is deformed along the radial direction of the winding core by the force, and the tab 110 is slightly tilted in the radial direction. After the scraper 390 rotates, it rebounds, and the mounting seat 330 moves upward at this time, the clamping assembly 400 opens, and the full-tab winding core 100 is transported to the next process, and the pretreatment process of the tab 110 is completed.

[0133] After the cylindrical tight full-tab winding is completed, the difference from the above is that after the scraper 390 overlaps with the tab 110 of the full-tab winding core 100 by 0.5-3mm, the scraper 390 starts to rotate, applying a force along the radial direction of the winding core to the tab 110. The tab 110 is deformed along the radial direction of the winding core by the force, and the tab 110 falls down in the radial direction.

[0134] In addition, square lithium-ion batteries can be divided into compact full-pole tab batteries and channel-type full-pole tab batteries.

[0135] After the square channel type full-ear winding is completed, the difference from the above is that after the scraper 390 overlaps with the ear 110 of the full-ear winding core 100 by 0.1-0.5mm, the scraper 390 starts to rotate, applying a force along the radial direction of the winding core to the ear 110. The ear 110 is deformed along the radial direction of the winding core by the force, and the ear 110 falls down in the radial direction.

[0136] After the square tight full-ear winding is completed, the difference from the above is that after the scraper 390 overlaps with the ear 110 of the full-ear winding core 100 by 0.5-3mm, the scraper 390 starts to rotate, applying a force along the radial direction of the winding core to the ear 110. The ear 110 is deformed along the radial direction of the winding core by the force, and the ear 110 falls down in the radial direction.
