Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to the technical field of rolling. More particularly, the present disclosure relates to a rolling adjustment assembly and a rolling device. BACKGROUND

[0002] Currently, in the production process of lithium batteries such as soft package batteries, after the process of coating active material on metal foil, a process of rolling the foil by using a pressure roller is often included to ensure that the active material is evenly distributed on the metal foil. In particular, in the production process of electrode sheets of solid-state batteries or composite solid-state electrolytes, in order to ensure the compaction degree of the electrode sheet to improve the performance of the battery, a pressure roller is often used for rolling. However, a non-coated area for processing a tab and other sub-components is often reserved on the metal foil, and the coated area is relatively thick compared to the non-coated area. Therefore, during the process of entering the rolling machine for rolling, the pressure on the coated and non-coated parts of the foil may not be consistent. For this problem, some existing solutions use fixed compensation materials to compensate for the thickness difference between the coated and non-coated parts. For example, in some existing devices, an adhesive tape can be provided around the outer periphery of the pressure roller on both sides of the pressure roller, or the pressure roller body can be provided with different diameters at the center and both sides. However, in the existing solutions, the compensation structure provided on the outer side of the pressure roller is a fixed or semi-fixed device, which is difficult to adjust after being set. When, for example, a new model needs to be produced, the position of the non-coated area to be compensated often needs to be changed, which often requires the compensation structure to be disassembled and installed again, or even the entire pressure roller to be replaced, which will greatly affect the production efficiency. And preparing multiple replacement compensation structures will greatly increase the production and maintenance costs.

[0003] Therefore, there is an urgent need to provide a rolling adjustment assembly to facilitate flexible position adjustment of the thickness compensation structure. SUMMARY

[0007] In some embodiments, the follow-up shaft further comprises two guide portions arranged along the axial direction of the follow-up shaft, the diameter of the guide portion is larger than the diameter of the follow-up shaft, and the outer diameter of the guide portion gradually decreases towards the center of the follow-up shaft along the axial direction of the follow-up shaft.

[0011] In some embodiments, the adjustment mechanism further comprises a fixed plate, the fixed plate is provided with an accommodation groove extending along the axial direction of the compression roller, and the lead screw is at least partially arranged in the accommodation groove.

[0012] In a second aspect, the present disclosure provides a rolling device for a foil, the rolling device comprising a compression roller and a rolling adjustment assembly according to the first aspect and the plurality of embodiments, and the compression roller is provided with one rolling adjustment assembly at each end.

Further, in some embodiments, by arranging the guide portion on the follow-up shaft, the position of the compensation belt can be limited to prevent lateral deflection during work. Further, in some embodiments, by arranging the lead screw and the sliding block matched therewith, the stability of the compensation mechanism during movement can be enhanced, and the adjustment error can be reduced.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present disclosure will be described clearly and completely in the embodiments of the present disclosure in combination with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present disclosure.

[0026] It should be understood that the terms "comprising" and "including" used in the specification and claims of the present disclosure indicate the presence of the described features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0027] It should also be understood that the terms used in the specification of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used in the specification and claims of the present disclosure, the singular forms "a", "an" and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should be further understood that the term "and / or" used in the specification and claims of the present disclosure means any combination of one or more of the associated listed items and all possible combinations thereof, and includes these combinations.

[0028] As used in the specification and claims of this specification, the term "if' can be interpreted as "when" or "upon" or "in response to a determination" or "in response to detecting" depending on the context. Similarly, the phrase "if determined" or "if [the described condition or event] is detected" can be interpreted as meaning "upon determining" or "in response to determining" or "upon detecting [the described condition or event]" or "in response to detecting [the described condition or event]", depending on the context.

[0029] At present, the process of producing lithium batteries such as soft package batteries often includes the process of uniformly coating active material on metal foil. In this related process, a press roller is often used to roll the metal foil to ensure that the active material is uniformly distributed on the metal foil. For example, after coating an active material coating on a metal foil strip with a relatively long length, the metal foil is sent to a rolling machine along its length direction, and a press roller arranged along the width direction of the metal foil is used to continuously roll it. In such a process, since a non-coating area for processing a tab and other sub-components often needs to be reserved on the metal foil, the coated part has a larger thickness compared with the non-coated part. Therefore, during the process of entering the rolling machine for rolling, the coated part and the non-coated part on the foil may not be subjected to consistent rolling force. In this case, the foil may locally deform under the action of the unevenly distributed rolling force.

[0030] For example, Figure 1 An exemplary structure of a foil with a coating is shown, in which a section along the length direction thereof is intercepted. In the case that the center portion 91 of the foil 90 is coated with a coating, since the center portion 91 coated with the coating has a greater thickness, it is subjected to a greater pressure than the uncoated portions 92 on both sides, and thus it is extended under the pressure greater than the uncoated portions 92 on both sides. Under the accumulation effect of continuous rolling, this deformation can cause the foil 90 to deform, and even cause it to tear.

[0031] For the problem that the coated and uncoated portions of the foil are subjected to different forces when rolling, some existing solutions are to use fixed compensation materials to compensate for the thickness difference between the coated and uncoated portions. For example, in some existing devices, adhesive tape can be provided around the outer periphery of the pressure roller to compensate for the above-mentioned thickness difference by the thickness of the adhesive tape. Or the pressure roller body is provided with different diameters in the middle and on both sides to compensate for the above-mentioned thickness difference by the diameter difference. However, in the above-mentioned solutions, since the compensation structures provided on the outer side of the pressure roller are fixed or semi-fixed devices, they are difficult to adjust after being set. In the case of, for example, producing a new type, the position of the uncoated portion to be compensated changes. At this time, it is often necessary to disassemble and install the compensation structure again, or even replace the entire pressure roller, which will greatly adversely affect the production efficiency. And preparing multiple replacement compensation structures will greatly increase the production and maintenance costs.

[0032] Therefore, the present disclosure provides a rolling adjustment assembly, in which a compensation mechanism movable along the axial direction of the pressure roller is provided, and an adjustment mechanism for driving the compensation mechanism to move, so that the compensation mechanism can be conveniently and flexibly adjusted in position on the pressure roller, thereby improving the production efficiency and reducing the production and maintenance costs.

[0033] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0034] Referring to Figure 2 and Figure 3 , Figure 2 An exemplary perspective view of a rolling adjustment assembly according to some embodiments of the present disclosure is shown; Figure 3 An exemplary perspective view of a rolling adjustment assembly according to some embodiments of the present disclosure is shown; Figure 2A partial enlarged view of the middle A part. In some embodiments, the roll adjustment assembly 100 can be arranged near the end of the press roll 50 in the axial direction of the press roll 50 for thickness compensation when the press roll 50 is used to roll the foil 90 coated with an active substance coating. The roll adjustment assembly includes a compensation mechanism 20 and an adjustment mechanism 10, wherein the compensation mechanism 20 includes a compensation belt 21 in the form of a ring, a portion of the compensation belt 21 is detachably sleeved on the surface of the press roll 50, so that the compensation belt 21 is attached to the surface of the press roll 50 and can be separated from the press roll 50 along with the rotation of the press roll 50. The position of the compensation belt 21 on the press roll 50 corresponds to the position of the uncoated part of the foil 90, thereby compensating for the thickness of the active substance coating with its own thickness. The adjustment mechanism 10 includes a drive assembly 11 drivingly connected with the compensation mechanism 20 to drive the compensation mechanism 20 to move in the axial direction of the press roll 50. Thus, the position of the compensation belt 21 of the compensation mechanism 20 relative to the press roll 50 can be adjusted in the axial direction of the press roll 50, so as to conveniently adapt to the change of the type of the foil 90 to be rolled, for example, in the case of the type of the foil 90 to be rolled needs to be changed, thereby saving the time required for debugging.

[0035] In particular, with reference to Figure 3 and Figure 4 , Figure 4 An exemplary sectional view of a partial portion of the roll adjustment assembly of some embodiments of the present disclosure is shown, in which a portion of the press roll 50 is cut off for clarity. The compensation mechanism 20 includes a fixed frame 22 and a follow-up shaft 25 arranged on the fixed frame 22, the axis of the follow-up shaft 25 is parallel to the axial direction of the press roll 50, and the follow-up shaft 25 is arranged at a distance from the press roll 50. The compensation belt 21 is, for example, a closed ring-shaped belt made of flexible materials such as polyurethane or butadiene rubber, and the compensation belt 21 is sleeved outside the follow-up shaft 25 and the press roll 50. In this embodiment, the fixed frame 22 includes a bottom plate 221 arranged horizontally and two compensation limiting plates 222 extending in the vertical direction on the upper surface of the bottom plate 221. The two compensation limiting plates 222 are arranged at a distance from each other in the axial direction of the follow-up shaft 25, and the distance between the two compensation limiting plates 222 is greater than the width of the compensation belt 21. The follow-up shaft 25 can be arranged between the two compensation limiting plates 222, and the axial ends of the follow-up shaft 25 are respectively connected with one of the compensation limiting plates 222. The compensation limiting plates 222 can be used to limit the compensation belt 21 in the axial direction of the press roll 50, so as to reduce the probability of lateral deviation or even falling off of the compensation belt 21, for example, in the case of accidental collision of the compensation belt 21.

[0036] In this embodiment, the follower shaft 25 is rotatably connected to the two compensation limiting plates 222. Thus, when the pressure roller 50 rotates, the follower shaft 25 can rotate simultaneously with the compensation belt 21, reducing the resistance exerted by the compensation belt 21 on the pressure roller 50. However, in some other embodiments (not shown), the follower shaft 25 can also be fixedly connected to the compensation limiting plates 222 and slide relative to the compensation belt 21 when it rotates with the pressure roller 50. This results in a stronger connection between the follower shaft 25 and the compensation limiting plates 222, enabling it to withstand higher tension and ensuring the stability of the compensation mechanism 20 when higher tension is required. In this case, the resistance to the pressure roller 50 can be reduced, for example, by configuring the follower shaft 25 to have a smooth surface or a smaller contact area with the compensation belt 21.

[0037] See Figure 6 , Figure 6 An exemplary cross-sectional view of a portion of a roll pressure adjustment assembly according to some embodiments of this disclosure is shown. Figure 6 In the illustrated embodiment, a bearing 26 may be provided on the portion of the follower shaft 25 adjacent to the two compensation limiting plates 222. This bearing 26 further reduces resistance as the follower shaft 25 rotates with the compensation belt 21, thereby improving the overall efficiency of the assembly. Furthermore, in some embodiments not shown, a tensioning mechanism may be provided between the follower shaft 25 and the pressure roller 50. This tensioning mechanism is used to tension the compensation belt 21 to enhance its stability during operation and reduce the probability of lateral deviation or slippage between it and the pressure roller 50 or the follower shaft 25. This tensioning mechanism may be, for example, an additional tensioning roller or a tensioning mechanism with adjustable tension, such as a tensioning wheel connected to an adjusting screw.

[0038] See also Figure 3 and Figure 4As shown in the figure, the follower shaft 25 is further provided with two guide portions 223 which are arranged along the axial direction of the compression roller 50, each of which is substantially annular and arranged around the outer periphery of the follower shaft 25, and the outer diameter of the guide portion 223 is greater than the diameter of the follower shaft 25. The guide portion 223 is used to limit and guide the compensation belt 21 along the axial direction of the follower shaft 25, so as to further reduce the probability of the compensation belt 21 being laterally offset during the machining process. For this purpose, the distance between the two guide portions 223 can be matched with the width of the compensation belt 21, or slightly greater than the width of the compensation belt 21. In addition, the outer diameter of at least a portion of the guide portion 223 gradually decreases from the two sides of the follower shaft 25 to the center direction along the axial direction of the follower shaft 25, so as to form a guide slope 2231 on the side of the guide portion 223 facing the compensation belt 21. The guide slopes 2231 of the two guide portions 223 are opposite to each other, and the guide slopes 2231 are used to guide the compensation belt 21 to the central portion of the follower shaft 25, so as to automatically correct the position of the compensation belt 21 when the compensation belt 21 is offset along the axial direction of the follower shaft 25, and reduce the position error of the compensation belt 21 on the compression roller 50. At the same time, the guide portion 223 can also be used to guide and position the compensation belt 21 when it is installed on the follower shaft 25, so as to facilitate the installation and replacement of the compensation belt 21, and shorten the required maintenance time.

[0039] In this embodiment, the guide portion 223 is a part of the follower shaft 25, which is formed by the circumferential side of the follower shaft 25 protruding radially outward. Those skilled in the art can understand that the specific forming method or connecting method of the guide portion 223 is not limited in the present disclosure. For example, in some embodiments, as shown in the figure, the guide portion 223 can be an independent annular member fixedly arranged outside the follower shaft 25, which can be fixedly connected to the follower shaft 25 by means of bolts or other components. In some other embodiments not shown, the guide portion 223 can be fixedly connected to the side wall of the two compensation limiting plates 222, or directly formed by the side wall of the compensation limiting plate 222 extending along the axial direction of the follower shaft 25. Figure 6

[0040] Figure 3 Figure 5 Figure 5 ​​​​An exemplary sectional view of the roller adjustment assembly in another direction is shown. As shown, the driving assembly 11 includes a motor 111, which can be a rotary driving motor such as a stepper motor, and a lead screw 112 fixedly connected with the output shaft of the motor 111. The lead screw 112 extends along the axial direction of the press roller 50, and one end of the lead screw 112 is fixedly connected to the output shaft of the motor 111 by means of a coupling or the like, so as to rotate with the rotation of the output shaft of the motor 111. The fixed frame 22 includes a driving receiving portion 224 extending downward from the bottom side of the bottom plate 221, and the driving receiving portion 224 is provided with a driving threaded hole 2241 corresponding to the lead screw 112. The lead screw 112 is threadedly connected with the driving threaded hole 2241 on the driving receiving portion 224, so as to drive the compensation mechanism 20 as a whole to move along the axial direction of the press roller 50 by the rotation of the output shaft. In this way, the position of the compensation mechanism 20 can be accurately controlled by controlling the motor 111, so as to further reduce the position error of the compensation belt 21 on the press roller 50 by adjustment.

[0041] Referring again to Figure 3 , the adjustment mechanism 10 further includes a fixed plate 12 and two guide assemblies 14. The guide assembly 14 includes a guide rail 141 fixedly arranged on the upper surface of the fixed plate 12 and a sliding block 142 capable of moving along the guide rail 141. In this embodiment, the motor 111 is fixedly arranged on one side of the fixed plate 12, and the output shaft thereof is arranged towards the fixed plate 12. The lead screw 112 is fixedly connected with the output shaft of the motor 111 and extends along the axial direction of the press roller 50. The two guide rails 141 also extend along the axial direction of the press roller 50 and are arranged on the lateral sides of the lead screw 112, respectively. The driving threaded hole 2241 on the driving receiving portion 224 of the compensation mechanism 20 is arranged on the lower side of the middle part of the bottom plate 221 in the lateral direction, and the bottoms of the two lateral parts of the bottom plate 221 are fixedly connected with the sliding blocks 142 by means of bolts or the like. In this way, the middle part of the bottom plate 221 is driven by the lead screw 112, and the two lateral parts are guided by the guide assemblies 14, which greatly improves the stability of the compensation mechanism 20 when moving along the axial direction of the press roller 50, reduces the error in the lateral direction, and thus improves the overall adjustment accuracy.

[0042] Referring again to Figure 3 and Figure 4The fixed plate 12 is further provided with a receiving groove 120 extending along the axial direction of the compression roller 50, and the side of the fixed plate 12 where the motor 111 is installed is provided with a through hole 121 extending along the axial direction of the compression roller 50. The output shaft of the motor 111 and the lead screw 112 pass through the through hole 121 and enter the receiving groove 120, and the lead screw 112 is at least partially arranged in the receiving groove 120. By arranging the receiving groove 120, the overall height of the roller pressure adjusting assembly is reduced, which is conducive to the miniaturization of the roller pressure adjusting assembly and is suitable for more production scenarios. At the same time, since the rotating components such as the lead screw 112 are embedded in the fixed plate 12, the probability of the operator or the maintenance personnel touching the rotating components is reduced, thereby improving the safety during production and maintenance.

[0043] Those skilled in the art can understand that, although the above describes a scheme in which the motor 111 and the lead screw 112 connected with the output shaft of the motor 111 are used as the driving assembly 11, the specific composition of the driving assembly 11 is not limited in the disclosure. For example, the driving assembly 11 can include a pneumatic cylinder, or the driving assembly 11 can be a linear driving mechanism composed of a motor and a synchronous belt. Moreover, the motor 111 can be arranged on one side of the fixed plate 12, but in some other embodiments, the motor 111 can also be arranged on the fixed frame 22, and the output shaft of the motor 111 is fixedly connected with a gear or a synchronous pulley, and a corresponding rack or synchronous belt is fixedly arranged on the fixed plate 12, so that the compensation mechanism 20 can move along the rack or synchronous belt simultaneously with the motor 111 under the driving of the motor 111. Thus, the distance between the output shaft of the motor 111 and the actually driven component can be reduced, the influence of the position error of each transmission component on the driving can be reduced, the overall transmission efficiency can be improved, and the overall error can be reduced.

[0044] In addition, since the coating or transfer of the foil 90 during production can cause the coating position of the foil 90 to laterally deviate, which can cause the compensation to fail or even cause the compensation belt 21 to press against the coating. In this regard, the adjustment mechanism 10 of the roll adjustment assembly can also adjust the position of the compensation belt 21 in the transverse direction of the press roller 50 during roll pressing. For example, in some embodiments not shown, the adjustment mechanism 10 includes a motor 111, and the roll adjustment assembly further includes a position detection sensor and a control module, both of which are electrically connected to the control module. The position detection sensor can be a visual sensor or a proximity sensor, etc., which is arranged at a corresponding position of the foil 90 that is not being rolled, to detect the edge position of the coating on the foil 90, to obtain position data corresponding to the position. The position detection sensor further transmits the position data to the control module, which calculates the required compensation amount of the foil 90 according to the position data, a pre-stored algorithm and standard position data, and further transmits the required compensation amount of the foil 90 to the adjustment mechanism 10 to drive the motor 111 of the adjustment mechanism 10 to make corresponding position adjustment, so that the position of the compensation belt 21 follows the movement of the coating edge position on the foil 90. Thus, through the roll adjustment assembly, lateral errors during the roll pressing of the foil 90 can also be compensated for, further improving product quality.

[0045] The roll adjustment assembly provided by the embodiments of the present disclosure can conveniently and flexibly adjust the position of the compensation mechanism on the press roller by arranging a compensation mechanism that can move in the axial direction of the press roller and an adjustment mechanism for driving the compensation mechanism to move, thereby improving production efficiency and reducing production and maintenance costs.

[0046] Referring to Figure 7 , Figure 7 An exemplary side view of a roll pressing device for foil according to some embodiments of the present disclosure is shown. The roll pressing device for foil 200 includes a frame 300, a press roller 50 and a backup roller 51 arranged on the frame 300, and two roll adjustment assemblies 100 arranged on both sides of the press roller 50, respectively, according to the above embodiments. Among them, the press roller 50 and the backup roller 51 on the frame 300 can rotate under the drive of the frame 300 and can roll press the foil 90 arranged between them. And the fixing frame of the adjustment mechanism of each roll adjustment assembly 100 can be fixedly arranged on the frame 300, and the compensation belt of the compensation mechanism thereof is sleeved on the outer side of the press roller 50 in the circumferential direction. Thus, when rolling processing the foil 90 having no-coating portions on both transverse sides, the two roll adjustment assemblies 100 can respectively compensate the thickness of the corresponding no-coating portions, and adjust the position according to the change of the foil 90, so that the thickness compensation can be carried out in the rolling process of the corresponding foil 90 according to different use requirements through simple operation.

[0047] It is understood by those skilled in the art that although the above describes a technical solution in which two roller pressure adjustment assemblies are respectively arranged on both sides of the pressure roller to compensate for the thickness of the foil, the present disclosure does not limit the arrangement position and number of the roller pressure adjustment assemblies. For example, in the case where more coating strips are arranged on the foil strip in the width direction, more roller pressure adjustment assemblies can be arranged in the axial direction of the pressure roller. Alternatively, in the case where only one side of the foil has a non-coating portion, a set of roller pressure adjustment assemblies can be arranged on only one side of the pressure roller, etc. In addition, in some embodiments not shown, the fixing plate of the adjustment mechanism of the above-mentioned roller pressure adjustment assembly can be formed as the table top of the machine frame 300, i.e., the motor and guide assembly of the roller pressure adjustment assembly are directly fixed to the table top, so that the device layout is more compact.

[0048] Although the embodiments of the present disclosure have been shown and described herein, it will be appreciated by those skilled in the art that these embodiments are provided only in an exemplary manner. Those skilled in the art can think of many changes, modifications and alternatives without departing from the idea and spirit of the present disclosure. It should be understood that various alternatives to the embodiments of the present disclosure described herein can be employed in practicing the present disclosure. The appended claims are intended to define the scope of protection of the present disclosure and thus cover equivalent or alternative solutions within the scope of the claims.
