Description

Technical Field

[0001] The present application relates to the field of battery production equipment, and in particular, to a tab pad module, a wrinkle removal tension roller and a roller press. Background Art

[0002] In battery production, electrode sheet rolling is a critical process. Before rolling, the electrode sheet material area is much thicker than the tab area. Therefore, during rolling, the material area significantly expands, while the tab area remains largely unchanged. Wrinkles form at the contact area between the material area and the tab. Furthermore, to prevent bulging during electrode coating, a thinning zone is typically created at the edge of the material area. The thinning zone is thinner than the normal material area, and during rolling, the thinning zone also expands less than the normal material area, resulting in inconsistent electrode sheet expansion, which impacts the normal operation of subsequent processes. A common method currently used is to apply a certain thickness of Teflon tape to the tension rollers of the pre- and post-rolling wrinkle removal devices at the corresponding tab locations to raise the tab. This, combined with the force applied by the tension rollers, extends the tab area. However, applying Teflon tape makes it difficult to effectively expand the thinning zone, and the ceramic coating on both sides of the positive electrode sheet material area makes expansion even more difficult. In addition, when changing the electrode model, the original Teflon tape needs to be removed and re-pasted, which is not only time-consuming and labor-intensive, but also involves destructive cutting of the electrode, seriously affecting the production capacity of the rolling process and wasting products.

[0003] To solve the above problems, the existing Chinese patent application number is CN202123389702.8, and the application date is December 29, 2021. It provides a gasket assembly that uses two semicircular gaskets that can be connected together by locating pins and fixed to the tension roller to replace Teflon tape. However, the gasket designed in this patent cannot adjust the inner diameter and can only be customized for tension rollers with specific roller diameters. Moreover, the gasket is fixed to the tension roller by the glue in the groove, which easily leaves glue marks, increases the difficulty of cleaning, and after being fixed, it cannot be translated on the tension roller to adjust the position to adapt the pole piece model. Summary of the Invention

[0004] The purpose of this application is to provide a tab pad module, a wrinkle removal tension roller and a roller press to solve the deficiencies in the prior art.

[0005] To achieve the above objectives, in a first aspect, the present application provides a tab heightening module for supporting the tabs in a pole piece before and after rolling. The tab heightening module comprises:

[0006] a spacer including two free ends along a length direction; and

[0007] A locking mechanism detachably connects the two free ends, and the end surfaces of the two free ends are brought close to each other and abutted against each other, so that the spacer sheet forms an annular spacer;

[0008] Wherein, the outer peripheral surface of the annular pad is used to abut against the tab.

[0009] As a further improvement of the above technical solution:

[0010] In combination with the first aspect, in one possible implementation, the locking mechanism includes:

[0011] A locking block, one end of which is provided with a slot for accommodating the two free ends; and

[0012] A pressing assembly is provided on the locking block and is used for fixing the two free ends in the slot.

[0013] In combination with the first aspect, in a possible implementation, the pressing assembly includes two locking pins, both of which are threadedly engaged with the locking block, and abutting ends of the two locking pins extend into the slot, and the abutting ends are used to abut the shim plate;

[0014] Wherein, a butt joint formed when the two free ends are butt-jointed is located between the abutting ends of the two locking pins.

[0015] In combination with the first aspect, in a possible implementation manner, the pressing assembly includes:

[0016] At least one locking pin, each of which is threadably engaged with the locking block, with an abutting end of the locking pin extending within the slot; and

[0017] A pressure plate is movably connected to the abutting end of the locking pin and is located in the slot, and the pressure plate is used to abut against the shim.

[0018] In combination with the first aspect, in a possible embodiment, the tab pad module is applied to a wrinkle removal tension roller, and the locking mechanism also includes a limiting component, which is arranged on the locking block, and the limiting component is used to connect to the roller shaft of the wrinkle removal tension roller to limit the movement of the locking block on the roller shaft.

[0019] In combination with the first aspect, in a possible implementation, the limiting component includes:

[0020] an expansion airbag, disposed inside the locking block;

[0021] An air nozzle valve, provided on the locking block and connected to the expansion airbag; and

[0022] A rubber strip, wherein a receiving groove is provided on a side of the locking block facing the roller shaft, the rubber strip is arranged on the locking block and located in the receiving groove, and the rubber strip is connected to the inflatable airbag;

[0023] The inflatable airbag drives the rubber strip to protrude out of the receiving groove through expansion, so that the rubber strip forms a friction fit with the roller shaft.

[0024] In combination with the first aspect, in a possible implementation manner, the limiting component is a strapping belt or a clamp.

[0025] In combination with the first aspect, in a possible implementation manner, the shim sheet includes a connected supporting portion and a locking portion along the width direction;

[0026] The support portion is used to abut against the tab, and along the cross section in the width direction, the support portion includes a connected slope section and a platform section, and along the width direction, from the platform section to the end of the slope section, the thickness of the slope section gradually decreases;

[0027] The locking portion is used to connect with the locking mechanism.

[0028] To achieve the above-mentioned purpose, in a second aspect, the present application further provides a wrinkle-removing tension roller for use in a roller press, wherein the wrinkle-removing tension roller comprises a roller shaft and at least one tab heightening module provided according to the above-mentioned first aspect;

[0029] The tab heightening module is detachably mounted on the roller shaft, the annular gasket is sleeved on the roller shaft, and the inner circumference of the annular gasket is in contact with the cylindrical surface of the roller shaft.

[0030] To achieve the above-mentioned purpose, in a third aspect, the present application further provides a roller press, comprising the wrinkle-removing tension roller provided according to the above-mentioned second aspect.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] The present application provides a tab padding module, a wrinkle removal tension roller, and a roller press. When the tab padding module is installed on the roller shaft of the wrinkle removal tension roller, the padding sheet is first bent around the roller shaft so that the two free ends of the padding sheet are close together and docked, and then locked and fixed by a locking mechanism. At this time, the padding sheet is constrained into a ring shape, that is, a ring pad is obtained. The inner circumference of the ring pad fits with the cylindrical surface of the roller shaft. The locking mechanism can be positioned on the roller shaft through an external limiter to prevent displacement and falling off. When the wrinkle removal tension roller tensions the pole piece, the outer circumference of the ring pad abuts against the tab of the pole piece, thereby padding the tab to prevent wrinkles from forming on the tab. Since the tab padding module itself is detachable, and the tab padding module and the roller shaft are also detachably matched, disassembling the tab padding module will not leave glue marks on the roller shaft, which is conducive to cleaning the roller shaft. Moreover, when changing the pole piece model, you can first release the fixation of the locking mechanism roller, and then push the entire pole ear pad module to move horizontally along the axial direction of the roller for adaptive adjustment. After the adjustment is completed, the locking mechanism and the roller can be fixed. There is no need to dismantle and reinstall the entire pole ear pad module. Compared with the existing technology, the disassembly and assembly adjustment is more convenient and quick, which greatly improves the operating efficiency and increases production capacity.

[0033] In addition, since the spacer and the locking mechanism are detachably connected, when the circumference of the roller changes, it is only necessary to cut a spacer of corresponding length according to the circumference of the roller. There is no need to customize the length according to the roller model. It is more versatile and practical.

[0034] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0051] Example 1

[0052] See also Figure 1 、 Figure 2 and Figure 3 This embodiment provides a tab heightening module 100, which is applied to a wrinkle-removing tension roller. The tab heightening module 100 is used to support the tabs in the pole piece before and after rolling to prevent wrinkles from forming on the tabs.

[0053] In this embodiment, the tab heightening module 100 includes a heightening plate 110 and a locking mechanism 120. The heightening plate 110 includes two free ends 111 along the length direction; the locking mechanism 120 detachably connects the two free ends 111 and brings the end surfaces of the two free ends 111 close to each other. Thus, in this embodiment, the heightening plate 110 is constrained into a ring shape by the locking mechanism 120, so that the heightening plate 110 forms an annular pad 110a (see Figure 3 ).

[0054] Among them, when the tab pad module 100 is installed on the roller shaft 200 of the wrinkle removal tension roller, the annular pad 110a is equivalent to being sleeved on the roller shaft 200, and the inner circumference of the annular pad 110a fits with the cylinder of the roller shaft 200, and the outer circumference of the annular pad 110a is used to abut against the tab to support the tab in the pole piece before and after rolling.

[0055] See also Figure 3 This embodiment also provides a wrinkle removal tension roller, which is applied to a roller press. The wrinkle removal tension roller includes a roller shaft 200 and at least one of the tab heightening modules 100 provided above.

[0056] Furthermore, in this embodiment, two tab pad modules 100 are provided, both of which are detachably arranged on the roller shaft 200 , and the locking mechanisms 120 in the two tab pad modules 100 are located on the side of the two annular pads 110 a facing away from each other.

[0057] See also Figure 1 、 Figure 2 and Figure 3 The method for assembling the wrinkle-removing tension roller provided in this embodiment includes the following steps:

[0058] S100: First, cut a spacer 110 of a corresponding length according to the circumference of the roller 200; of course, a spacer 110 of a corresponding length can also be prepared in advance.

[0059] S200: Then the side surface of the inner circumference of the annular gasket 110a of the spacer 110 is abutted against the cylindrical surface of the roller shaft 200, and then the spacer 110 is bent around the roller shaft 200 so that the two free ends 111 of the spacer 110 are close to each other and connected.

[0060] S300 : The two free ends 111 are locked and fixed by the locking mechanism 120 to form an annular gasket 110 a , and the inner circumferential surface of the annular gasket 110 a is in contact with the cylindrical surface of the roller shaft 200 .

[0061] S400 : Execute the above steps S100 to S300 to complete the installation of another tab pad module 100 on the roller 200 , while ensuring that the locking mechanisms 120 in the two tab pad modules 100 are located on the side of the two annular pads 110 a facing away from each other.

[0062] S500: Adjust the distance between the two tab pad modules 100 according to the type of the pole piece. Specifically, the entire tab pad module 100 is pushed to translate along the axis of the roller 200 so that the outer circumference of the annular pad 110a in the tab pad module 100 can abut against the tab of the pole piece.

[0063] S600 : Respectively position the locking mechanisms 120 of the two adjusted tab heightening modules 100 on the roller shaft 200 in a detachable manner.

[0064] Specifically, in some embodiments, the locking mechanism 120 can be detachably connected to the roller shaft 200 via a limiting member, wherein the limiting member can be a screw that passes through the locking mechanism 120 and is threadedly engaged with the roller shaft 200.

[0065] In other embodiments, the limiting member may be a strapping belt or a clamp, so that the locking mechanism 120 is fastened to the roller shaft 200 by the strapping belt or the clamp to fix the locking mechanism 120 .

[0066] In some other embodiments, the locking mechanism 120 may be directly tied to the roller 200 using a rope or wire to fix the locking mechanism 120 .

[0067] It should be understood that the above is merely an example and is not intended to limit the scope of protection of this application.

[0068] In some embodiments, in step S200, the spacer sheets 110 may be first bundled into an annular pad 110a by the locking mechanism 120, and then the tab spacer module 100 may be assembled onto the roller 200. When two tab spacer modules 100 are assembled, it is necessary to ensure that the locking mechanisms 120 in the two tab spacer modules 100 are located on the sides of the two annular pads 110a facing away from each other to prevent the locking mechanisms 120 from interfering with the transport of the tab sheets.

[0069] Furthermore, this embodiment also provides a roller press for rolling the electrode sheets, wherein the roller press comprises a roller pressing module for rolling the electrode sheets and the wrinkle-removing tension roller provided above.

[0070] The wrinkle removal tension roller provided in this embodiment has the following advantages:

[0071] (1) When the wrinkle-removing tension roller tensions the pole piece, the outer peripheral surface of the annular pad 110a contacts the pole tab of the pole piece, thereby raising the pole tab to prevent wrinkles from forming on the pole tab.

[0072] (2) Since the tab pad module 100 itself is detachable, and the tab pad module 100 and the roller 200 are also detachably matched, disassembling the tab pad module 100 will not leave glue marks on the roller 200, which is conducive to cleaning the roller 200.

[0073] (3) When changing the pole piece model, the locking mechanism 120 and the roller 200 can be released first, and then the entire pole tab pad module 100 can be pushed horizontally along the axis direction of the roller 200 for adaptive adjustment. After the adjustment is completed, the locking mechanism 120 and the roller 200 can be fixed. There is no need to dismantle and reinstall the entire pole tab pad module 100. Compared with the existing technology, it is more convenient and quick, greatly improving the working efficiency and increasing the production capacity.

[0074] (4) Since the spacer 110 and the locking mechanism 120 are detachably connected, when the circumference of the roller 200 changes, it is only necessary to cut the spacer 110 of the corresponding length according to the circumference of the roller 200. There is no need to customize the length according to the model of the roller 200, which is more universal and practical.

[0075] Example 2

[0076] See also Figure 1 、 Figure 2 and Figure 3 This embodiment provides a tab pad module 100. This embodiment is an improvement made on the technical basis of the above embodiment 1. Compared with the above embodiment 1, the difference is:

[0077] In this embodiment, the locking mechanism 120 includes a locking block 121 and a pressing assembly 122. One end of the locking block 121 is provided with a card slot 1210 for accommodating the two free ends 111; the pressing assembly 122 is arranged on the locking block 121, and the pressing assembly 122 is used to fix the two free ends 111 in the card slot 1210.

[0078] As can be understood, when the two free ends 111 of the spacer block come close to each other and butt joint, a butt joint seam is formed. The two free ends 111 are fixed in the slots 1210 of the locking block 121 by the pressing assembly 122 to prevent the two free ends 111 from separating, thereby preventing the butt joint from expanding, and thus maintaining the inner circumference of the annular gasket 110a in contact with the cylindrical surface of the roller shaft 200.

[0079] Please also refer to Figure 4 and Figure 5 Furthermore, the pressing assembly 122 includes a pressing plate 1220 and at least one locking pin 1221. In this embodiment, two locking pins 1221 are provided, wherein both locking pins 1221 are threadedly engaged with the locking block 121 and each has an abutting end, and the abutting ends of the two locking pins 1221 extend into the slot 1210. The pressing plate 1220 is disposed in the slot 1210 and is movably connected to the abutting ends of the two locking pins 1221.

[0080] Thus, when the two free ends 111 of the spacer 110 need to be fixed, the two locking pins 1221 are rotated to push the pressure plate 1220 against at least a portion of the outer circumference of the annular pad 110a, so that the two free ends 111 are clamped by the pressure plate and the slot 1210, thereby achieving the fixation of the two free ends 111. When disassembly is required, the two locking pins 1221 are rotated in the opposite direction to release the fixation of the two free ends 111. The tab spacer module 100 provided in this embodiment is more convenient and quick to disassemble and install, and the entire tab spacer module 100 is reusable, saving materials and costs.

[0081] In some embodiments, the clamping assembly 122 includes only two locking pins 1221, both of which are threadedly engaged with the locking block 121. The abutting ends of the two locking pins 1221 extend into the slot 1210 and are used to abut the spacer 110. The abutting seam formed when the two free ends 111 are butted together is located between the abutting ends of the two locking pins 1221.

[0082] Optionally, the locking pin 1221 is a screw or a bolt. Of course, it can also be other rods with threads.

[0083] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 Furthermore, the spacer 110 includes a supporting portion 112 and a locking portion 113 connected as one piece along the width direction. The supporting portion 112 is used to abut against the tab, and the locking portion 113 is used to connect with the locking mechanism 120.

[0084] Specifically, the bottom surface of the support portion 112 is a smooth plane or curved surface, which is used to fit with the cylindrical surface of the roller 200. Along the cross section in the width direction, the support portion 112 includes a slope section 1120 and a platform section 1121 connected as one body. Furthermore, and along the width direction, from the platform section 1121 to the end of the slope section 1120, the thickness of the slope section 1120 gradually decreases, thereby achieving a smooth transition in thickness. Among them, the inclined surface formed by the slope section 1120 is located on the outer peripheral surface of the annular pad 110a. As a result, the slope section 1120 can penetrate into the thinning area of the pole piece, and the continuous slope design from thin to thick ensures that during the extension process, the thinning area and the pole ear will not produce marks due to the sudden change in the thickness of the pad 110.

[0085] The locking portion 113 is protruding from the side of the support portion 112 away from the roller shaft 200, thereby forming a "Z" shape with the support portion 112. The locking portion 113 can be inserted or embedded into the slot 1210 of the locking block 121 and clamped by the clamping assembly 122. Furthermore, the protruding position of the locking portion 113 on the side of the support portion 112 away from the roller shaft 200 creates a clearance space 114 between the bottom of the locking portion 113 and the outer cylindrical surface of the roller shaft 200, facilitating the installation of the locking block 121 and preventing interference between the bottom surface of the locking block 121 and the roller shaft 200.

[0086] Example 3

[0087] See also Figure 1 、 Figure 3 and Figure 4 This embodiment provides a tab pad module 100. This embodiment is an improvement made on the technical basis of the above-mentioned embodiment 1 or embodiment 2. Compared with the above-mentioned embodiment 1 or embodiment 2, the difference is:

[0088] In this embodiment, the locking mechanism 120 further includes a limiting assembly 123 , which is disposed on the locking block 121 . The limiting assembly 123 is used to connect to the roller shaft 200 of the tension roller to limit the movement of the locking block 121 on the roller shaft 200 .

[0089] Optionally, the limiting component 123 can be assembled with the locking block 121 into a non-detachable whole, or can be assembled into a detachable component.

[0090] Furthermore, the limiting assembly 123 includes an inflatable airbag 1230, a valve 1231, and a rubber strip 1232. The inflatable airbag 1230 is disposed within the locking block 121, i.e., the locking block 121 defines an inner cavity for accommodating the inflatable airbag 1230. The valve 1231 is disposed on the locking block 121 and connected to the inflatable airbag 1230, thereby enabling the inflatable airbag 1230 to be inflated and deflated via the valve 1231. A receiving groove 1211 is defined on the side of the locking block 121 facing the roller shaft 200. The rubber strip 1232 is disposed within the locking block 121 and is located within the receiving groove 1211. The rubber strip 1232 is connected to the inflatable airbag 1230.

[0091] As can be understood, when the locking block 121 needs to be fixed, the expansion bladder 1230 is inflated through the air nozzle valve 1231. The expansion bladder 1230 drives the rubber strip 1232 to protrude out of the receiving groove 1211, so that the rubber strip 1232 forms a friction fit with the roller shaft 200, thereby limiting the movement of the locking mechanism 120 on the roller shaft 200, thereby completing the positioning of the tab heightening module 100 on the roller shaft 200. When adjusting or removing the tab heightening module 100, the expansion bladder 1230 is first deflated through the air nozzle valve 1231.

[0092] In some embodiments, a plurality of locking mechanisms 120 may be distributed along the circumference of the annular pad 110 a to improve the stability of the tab pad module 100 after it is positioned on the roller 200 .

[0093] In some embodiments, the limiting assembly 123 also includes a strapping tape or a clamp, which fixes the locking block 121 to the roller 200 through the strapping tape or the clamp, and then inflates through the air nozzle valve 1231 to improve the stability of the tab pad module 100 after it is fixed on the roller 200.

[0094] In other embodiments, the limiting component 123 may also be selected to be only a strapping belt or a clamp.

[0095] The tab heightening module 100 provided in this embodiment is fixed and loosened on the tension roller by means of an air pressure control device, and will not leave glue marks on the roller 200 , which is beneficial to the cleaning of the roller 200 .

[0096] The above describes in detail the optional implementation methods of the embodiments of the present application in conjunction with the accompanying drawings. However, the embodiments of the present application are not limited to the specific details of the above implementation methods. Within the technical concept of the embodiments of the present application, various simple modifications can be made to the technical solutions of the embodiments of the present application, and these simple modifications all fall within the scope of protection of the embodiments of the present application.

[0097] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner unless there is any contradiction. In order to avoid unnecessary repetition, the embodiments of this application will no longer separately describe various possible combinations.

[0098] In addition, the various implementation methods of the embodiments of the present application can be arbitrarily combined, as long as they do not violate the ideas of the embodiments of the present application, they should also be regarded as the contents disclosed in the embodiments of the present application.
