[0048] With the development of new energy technology, batteries are used more and more widely, for example, in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and electric tools, etc.

[0049] As a key component of the battery, the production efficiency of the pole piece is crucial in the entire battery production process and directly affects the quality and economic benefits of the battery. In the battery, it is usually necessary to glue the pole ear of the pole piece to improve the reliability and service life of the battery.

[0050] In the current tab gluing process, after the conveyor line transports the pole piece to the gluing station, the gluing device starts gluing the pole piece. During the entire process of the gluing device gluing the pole piece, the conveyor belt needs to stop conveying. After the gluing device completes the gluing work on the pole piece, the conveyor line continues to convey the pole piece. The waiting during the tab gluing process makes the efficiency of the entire tab gluing process low, which seriously affects the overall production efficiency of the pole piece.

[0051] Based on the above considerations, the present application designs a pole piece processing device, which includes a conveyor belt, a gluing device and a moving device, wherein the conveyor belt is used to convey the pole piece, and the gluing device is used to glue the pole ear of the pole piece. The moving device is connected to the gluing device, and the moving device is used to drive the gluing device to move in a direction parallel to the conveying direction of the conveyor belt.

[0052] During the process of gluing the pole ears with the pole piece processing equipment of the above technical solution, while the conveyor belt transports the pole ears, the moving device drives the gluing device to move synchronously with the pole ears, so that the gluing device remains relatively still with the pole ears in the conveying direction, and the gluing device glues the pole ears while moving along the conveying direction. During the entire pole ear gluing process, the conveyor belt does not need to pause and wait, which can shorten the time of the entire pole ear gluing process, thereby effectively improving the production efficiency of the pole ears.

[0054] refer to Figures 1 to 3 The embodiment of the present application provides a processing device for a pole piece 110, which includes a conveyor belt 10, a gluing device 20 and a moving device 30. The conveyor belt 10 is used to convey the pole piece 110, and the gluing device 20 is used to glue the pole lug 111 of the pole piece 110. The moving device 30 is connected to the gluing device 20, and the moving device 30 is used to drive the gluing device 20 to move in a direction parallel to the conveying direction X of the conveyor belt 10.

[0055] Exemplarily, the conveyor belt 10 is a basic component of the electrode piece 110 processing equipment, and is responsible for conveying the electrode piece 110. The conveyor belt 10 may include a driving component and a belt body, the driving component drives the belt body to move along the conveying direction X, the electrode piece 110 is located on the belt body, and the belt body drives the electrode piece 110 to move along the conveying direction X. Optionally, the conveying speed of the conveyor belt 10 is adjustable to match the speed requirements of different processing steps.

[0056] The gluing device 20 is used to glue the tabs 111 of the pole piece 110 to improve the overall reliability of the pole piece 110. Exemplarily, the gluing device 20 can be a liquid glue on the tabs 111, or a solid tape 200 on the tabs 111. The solid tape 200 can be, but is not limited to, a transparent tape 200, a cloth-based tape 200, an electrical tape 200, or a foam tape 200, etc.

[0057] The moving device 30 is used to drive the gluing device 20 to move in a direction parallel to the conveying direction X of the conveyor belt 10. For example, the moving device 30 can be, but is not limited to, a telescopic rod structure, a slide rail slider structure, a screw structure, or an electric cylinder structure to drive the gluing device 20 to move in a direction parallel to the conveying direction X of the conveyor belt 10.

[0058] The gluing device 20 may be directly connected to the moving device 30 , or may be restricted on the moving device 30 through other components.

[0059] As an example, the moving device 30 includes a driving member, a slide rail and a slider. The slide rail is extended in a direction parallel to the conveying direction X. The slider is movably connected to the slide rail and is movable on the slide rail in a direction parallel to the conveying direction X. The driving motor is connected to the slider and is used to drive the slider to move in a direction parallel to the conveying direction X. The gluing device 20 is connected to the slider so that the slider can drive the gluing device 20 to move in a direction parallel to the conveying direction X.

[0060] As another example, the moving device 30 includes a motor, a screw and a screw nut. The motor is connected to the screw and is used to drive the screw to rotate. The screw is extended in a direction parallel to the conveying direction X. The screw nut is sleeved on the screw and can convert the rotational motion of the screw into its own linear motion in a direction parallel to the conveying direction X. The gluing device 20 is connected to the screw nut so that the screw nut can drive the gluing device 20 to move in a direction parallel to the conveying direction X.

[0061] It should be noted that the conveyor belt 10 conveys the electrode 110 at a first speed. When the gluing device 20 is gluing the electrode 110, the moving device 30 drives the gluing device 20 to move along the conveying direction X at a second speed, and the first speed is the same as the second speed. After the gluing device 20 completes the gluing work, the moving device 30 drives the gluing device 20 to move and reset in a direction parallel to and opposite to the conveying direction X at a third speed, and the third speed is greater than the first speed. Further, the third speed can be, but is not limited to, twice, three times, or four times the first speed.

[0062] During the process of gluing the pole piece 111 by the pole piece 110 processing equipment of the above technical solution, while the conveyor belt 10 conveys the pole piece 110, the moving device 30 drives the gluing device 20 to move synchronously with the pole piece 110, so that the gluing device 20 remains relatively still with the pole piece 110 in the conveying direction X, and the gluing device 20 glues the pole piece 111 while moving along the conveying direction X. During the entire process of gluing the pole piece 111, the conveyor belt 10 does not need to pause and wait, which can shorten the time of the entire pole piece 111 gluing process, thereby effectively improving the production efficiency of the pole piece 110.

[0063] In some embodiments, the movable device 30 includes a first movable component 31 and a second movable component 32, the first movable component 31 is extended along the conveying direction X, the second movable component 32 is movably connected to the first movable component 31, and the second movable component 32 is movable on the first movable component 31 in a direction parallel to the conveying direction X, and the glue laminating device 20 is connected to the second movable component 32.

[0064] The second movable part 32 may be directly connected to the first movable part 31, or may be restricted on the first movable part 31 through other parts. In some examples, the first movable part 31 and the second movable part 32 are detachably connected to reduce the difficulty of maintenance.

[0065] The glue sticking device 20 may be directly connected to the second movable part 32, or may be restricted on the second movable part 32 by other parts. In some examples, the glue sticking device 20 and the second movable part 32 are detachably connected to reduce the difficulty of maintenance.

[0066] The first moving component 31 is a main functional component for driving the gluing device 20 to move in a direction parallel to the conveying direction X of the conveyor belt 10. The first moving component 31 can be, but is not limited to, a telescopic rod structure, a slide rail slider structure, a screw rod structure, or an electric cylinder structure to drive the gluing device 20 to move in a direction parallel to the conveying direction X of the conveyor belt 10.

[0067] As an example, the moving device 30 includes a driving member and a first moving component 31, the first moving component 31 includes a slide rail and a slider, the slide rail is extended in a direction parallel to the conveying direction X, the slider is movably connected to the slide rail and can be moved on the slide rail in a direction parallel to the conveying direction X, the driving motor is connected to the slider and is used to drive the slider to move in a direction parallel to the conveying direction X, and the gluing device 20 is connected to the slider so that the slider can drive the gluing device 20 to move in a direction parallel to the conveying direction X.

[0068] As another example, the moving device 30 includes a motor and a first moving component 31, the first moving component 31 includes a screw and a screw nut, the motor is connected to the screw and is used to drive the screw to rotate, the screw is extended in a direction parallel to the conveying direction X, the screw nut is sleeved on the screw and can convert the rotational motion of the screw into its own linear motion in a direction parallel to the conveying direction X, and the gluing device 20 is connected to the screw nut so that the screw nut can drive the gluing device 20 to move in a direction parallel to the conveying direction X.

[0069] The second movable component 32 of the above technical solution connects the gluing device 20 and the first movable component 31. The second movable component 32 can play a transitional shock-absorbing role, which can reduce the shaking of the gluing device 20 during movement, thereby improving the stability of the pole piece 110 during the gluing process.

[0070] In some embodiments, the first movable component 31 includes a first rail 311 and a second rail 312 , which are respectively arranged on both sides of the conveyor belt 10 in a direction intersecting with the conveying direction X, and the second movable component 32 is connected to the first rail 311 and the second rail 312 .

[0071] Exemplarily, the first rail 311 and the second rail 312 may be respectively arranged on both sides of the conveyor belt 10 along its own width direction Y, or the first rail 311 and the second rail 312 may also be respectively arranged on both sides of the conveyor belt 10 along its own thickness direction Z.

[0072] The first rail 311 and the second rail 312 are both extended in a direction parallel to the conveying direction X, and the second moving member 32 is movably provided in a direction parallel to the conveying direction X on the first rail 311 and the second rail 312 .

[0073] The structures of the first rail 311 and the second rail 312 may be the same or different. The first rail 311 and the second rail 312 may be, but are not limited to, structures such as telescopic rods, slide rails, or screw rods. As an example, the first rail 311 and the second rail 312 have the same structure, which can simplify the manufacturing process and help reduce costs.

[0074] The above technical solution can effectively improve the stability of the second movable component 32 by introducing the first rail 311 and the second rail 312 and connecting the second movable component 32 to the first rail 311 and the second rail 312 , thereby improving the reliability of the movable device 30 .

[0075] In some embodiments, the second movable member 32 includes a first beam 321 and a second beam 322, the first beam 321 connects the first movable member 31 and the second beam 322, and the second beam 322 extends along the width direction Y of the conveyor belt 10. The glue sticking device 20 is movably connected to the second beam 322, and the glue sticking device 20 is movably arranged on the second beam 322 along the width direction Y.

[0076] Exemplarily, the first beam 321 connects the first moving part 31 and the second beam 322, and the first beam 321 is a main functional component for transitional shock absorption. The second beam 322 is a main functional component for driving the glue sticking device 20 to move along the width direction Y. The second beam 322 can be, but is not limited to, a telescopic rod structure, a slide rail slider structure, a screw rod structure, or an electric cylinder structure to drive the glue sticking device 20 to move along the width direction Y.

[0077] As an example, the second beam 322 includes a driving member, a slide rail and a slider. The slide rail is extended along the width direction Y. The slider is movably connected to the slide rail and can be moved on the slide rail along the width direction Y. The driving motor is connected to the slider and is used to drive the slider to move along the width direction Y. The glue device 20 is connected to the slider so that the slider can drive the glue device 20 to move along the width direction Y.

[0078] As another example, the moving device 30 includes a motor, a screw and a screw nut. The motor is connected to the screw and is used to drive the screw to rotate. The screw is extended along the width direction Y. The screw nut is sleeved on the screw and can convert the rotational motion of the screw into its own linear motion along the width direction Y. The gluing device 20 is connected to the screw nut so that the screw nut can drive the gluing device 20 to move along the width direction Y.

[0079] It is understandable that, in the process of conveying the electrode piece 110 in the conveying direction X, the electrode piece 110 is easily deflected, which easily causes misalignment between the gluing device 20 and the electrode tab 111. The gluing device 20 can move along the width direction Y, that is, it can be aligned with the electrode tab 111 by moving itself in the width direction Y.

[0080] In this way, the above technical solution enables the glue sticking device 20 to move along the width direction Y, which can improve the alignment accuracy between the glue sticking device 20 and the tab 111, and can effectively improve the glue sticking quality.

[0081] In some embodiments, the gluing device 20 includes a first gluing component 21 and a second gluing component 22. The first gluing component 21 and the second gluing component 22 are relatively arranged along the thickness direction Z of the conveyor belt 10, and are respectively used to glue the opposite side surfaces of the pole ear 111 along the thickness direction Z.

[0082] Exemplarily, the structures of the first adhesive component 21 and the second adhesive component 22 may be the same or different. As an example, the structures of the first adhesive component 21 and the second adhesive component 22 are the same, which can simplify the preparation process and help reduce costs.

[0083] The above technical solution can simultaneously glue the two opposite surfaces of the pole ear 111 along the thickness direction Z. During the gluing process, the first glue component 21 and the second glue component 22 can support each other, reducing the risk of gluing failure due to the drooping of the pole ear 111, and can improve the gluing quality and product yield.

[0084] In some embodiments, the first glue sticking assembly 21 includes a first glue sticking head 211 and a first tape unwinding component 212. The first tape unwinding component 212 is connected to the first glue sticking head 211. The first tape unwinding component 212 is used to provide the tape 200. The first glue sticking head 211 is configured to be movable along the thickness direction Z and is used to attach the tape 200 to the pole ear 111.

[0085] Exemplarily, the first glue sticking head 211 is the main functional component of the first glue sticking assembly 21 for sticking glue to the pole tab 111. The first tape unwinding component 212 is used to provide the tape 200 to the first glue sticking head 211. The first glue sticking head 211 is provided with the tape 200 on the side surface close to the conveyor belt 10 in the thickness direction Z. The first glue sticking head 211 moves along the thickness direction Z and close to the pole tab 111 to attach the tape 200 to the pole tab 111; after the first glue sticking head 211 completes the attachment of the tape 200, the first glue sticking head 211 moves along the thickness direction Z and away from the pole tab 111 to detach from the pole piece 110, so that the pole piece 110 can be normally conveyed along the conveying direction X on the conveyor belt 10.

[0086] It is understandable that the first adhesive head 211 may be provided with a cutting structure and a pulling structure, the pulling mechanism is used to pull the tape 200 provided by the first tape unwinding component 212, and the cutting structure is used to cut the tape 200 attached to the tab 111 from the tape 200 pulled by the pulling structure when the first adhesive head 211 attaches the tape 200 to the tab 111. The cutting structure and the pulling structure may be provided inside the first adhesive head 211 or outside the first adhesive head 211.

[0087] The above technical solution introduces the first tape unwinding component 212, which not only facilitates the replacement of the tape 200 roll when the tape 200 is used up, but also increases the tape 200 capacity of the first adhesive component 21 to reduce the replacement frequency and reduce time waste, thereby helping to improve the overall production efficiency of the pole piece 110.

[0088] In some embodiments, the first glue application component 21 further includes a first roller 213 . The first roller 213 is disposed between the first glue application head 211 and the first adhesive tape unwinding component 212 . The first roller 213 is used to tension the adhesive tape 200 .

[0089] Exemplarily, the main function of the first roller 213 is to adjust and maintain the tension of the tape 200. By applying appropriate tension to the tape 200, the tape 200 can maintain a stable stretched state during the entire laminating process, reducing the risk of laminating defects caused by relaxation or over-stretching of the tape 200.

[0090] The first roller 213 is arranged between the first adhesive tape head 211 and the first adhesive tape unwinding component 212, so as to pre-adjust the tension of the adhesive tape 200 before it enters the critical stage of adhesive tape. This position setting helps the adhesive tape 200 to achieve a smooth transition from unwinding to attaching, and at the same time, the adhesive tape 200 has an appropriate tension before being attached to the tab 111.

[0091] Optionally, the first roller 213 may be made of materials such as rubber, polyurethane or silicone, which can not only provide sufficient friction to adjust the tension but also reduce damage to the surface of the tape 200 .

[0092] The above technical solution enhances the tension control of the tape 200 by introducing the first roller 213, which not only improves the stability and consistency of the tape 200 during the bonding process, but also effectively reduces the risk of breakage, deformation or accidental adhesion of the tape 200 due to improper tension, thereby improving the reliability of the bonding device 20.

[0093] In some embodiments, the first adhesive head 211 includes a first movable portion 2111 and a first supporting portion 2112, the first movable portion 2111 is used to attach the adhesive tape 200 to the pole tab 111, the first supporting portion 2112 is used to support the pole tab 111, the first supporting portion 2112 is connected to the first movable portion 2111, and the first movable portion 2111 is configured to be movable relative to the first supporting portion 2112 along the thickness direction Z of the conveyor belt 10. The first supporting portion 2112 is disposed on a side of the first movable portion 2111 away from the conveyor belt 10 along the width direction Y of the conveyor belt 10, and the first supporting portion 2112 protrudes from a side surface of the first movable portion 2111 along the thickness direction Z.

[0094] Exemplarily, the first movable part 2111 is the main functional component of the first glue sticking head 211 for sticking glue to the pole lug 111. The first movable part 2111 is provided with a tape 200 on the surface of one side close to the conveyor belt 10 in the thickness direction Z. The first supporting part 2112 is used to support the pole lug 111 before the tape 200 is attached to the pole lug 111.

[0095] It can be understood that when the pole piece 110 is located on the conveyor belt 10, at least part of the pole ear 111 extends out of the conveyor belt 10 in the width direction Y of the conveyor belt 10, and the part of the ear extending out of the conveyor line is suspended in the air to facilitate the gluing device 20 to glue the pole ear 111.

[0096] During the process of the first adhesive head 211 moving along the thickness direction Z and close to the pole lug 111, the first movable part 2111 and the first supporting part 2112 move synchronously. Since the first supporting part 2112 protrudes from the side surface of the first movable part 2111 close to the conveyor belt 10 along the thickness direction Z, the first supporting part 2112 will first contact the pole lug 111. After the first supporting member supports the pole lug 111, since the first movable part 2111 can move relative to the first supporting part 2112 along the thickness direction Z of the conveyor belt 10, the first movable part 2111 can further move along the thickness direction Z and close to the pole lug 111 to attach the tape 200 to the pole lug 111.

[0097] The first support portion 2112 may be directly connected to the first movable portion 2111, or may be restricted on the first movable portion 2111 by other components. In some examples, the first movable portion 2111 and the first support portion 2112 may be detachably connected to reduce the difficulty of maintenance.

[0098] Optionally, the first supporting portion 2112 may be, but is not limited to, a plate-like structure, a block-like structure, a columnar structure, or the like.

[0099] The above technical solution can support the pole ear 111 before gluing the pole ear 111 by introducing the first support member, thereby reducing the risk of tearing the pole ear 111 or causing attachment defects during the gluing process due to the drooping of the suspended part of the pole ear 111, thereby effectively improving the product yield.

[0100] In some embodiments, the second glue applying assembly 22 includes a second glue applying head and a second tape unwinding component, the second tape unwinding component is connected to the second glue applying head, the second tape unwinding component is used to provide the tape 200, the second glue applying head is configured to be movable along the thickness direction Z, and is used to attach the tape 200 to the pole ear 111.

[0101] Exemplarily, the second glue sticking head is the main functional component of the second glue sticking assembly 22 for sticking glue to the pole tab 111. The second tape unwinding component is used to provide the tape 200 to the second glue sticking head. The second glue sticking head is provided with the tape 200 on the side surface close to the conveyor belt 10 in the thickness direction Z, and the second glue sticking head moves along the thickness direction Z and close to the pole tab 111 to attach the tape 200 to the pole tab 111; after the second glue sticking head completes the attachment of the tape 200, the second glue sticking head moves along the thickness direction Z and away from the pole tab 111 to detach from the pole piece 110, so that the pole piece 110 can be normally conveyed along the conveying direction X on the conveyor belt 10.

[0102] It is understandable that the second adhesive taping head may be provided with a cutting structure and a pulling structure, the pulling mechanism is used to pull the tape 200 provided by the second tape unwinding component, and the cutting structure is used to cut the tape 200 attached to the tab 111 from the tape 200 pulled by the pulling structure when the second adhesive taping head attaches the tape 200 to the tab 111. The cutting structure and the pulling structure may be provided inside the second adhesive taping head or outside the second adhesive taping head.

[0103] The above technical solution introduces a second tape unwinding component, which not only facilitates the replacement of the tape 200 roll when the tape 200 is used up, but also increases the tape 200 capacity of the second adhesive component 22 to reduce the replacement frequency and reduce time waste, thereby helping to improve the overall production efficiency of the pole piece 110.

[0104] In some embodiments, the second glue application component 22 further includes a second roller, which is disposed between the second glue application head and the second tape unwinding component, and is used to tension the tape 200 .

[0105] Exemplarily, the main function of the second roller is to adjust and maintain the tension of the tape 200. By applying appropriate tension to the tape 200, the tape 200 can maintain a stable stretched state during the entire gluing process, reducing the risk of adhesion defects caused by relaxation or excessive stretching of the tape 200.

[0106] The second roller is arranged between the second adhesive tape head and the second adhesive tape unwinding component so as to pre-adjust the tension of the adhesive tape 200 before it enters the critical stage of adhesive tape. This position setting helps the adhesive tape 200 to achieve a smooth transition from unwinding to attaching, and at the same time, the adhesive tape 200 has an appropriate tension before being attached to the tab 111.

[0107] Optionally, the second roller may be made of materials such as rubber, polyurethane or silicone, which can not only provide sufficient friction to adjust the tension but also reduce damage to the surface of the adhesive tape 200 .

[0108] The above technical solution enhances the tension control of the tape 200 by introducing a second roller, which not only improves the stability and consistency of the tape 200 during the bonding process, but also effectively reduces the risk of breakage, deformation or accidental adhesion of the tape 200 due to improper tension, thereby improving the reliability of the bonding device 20.

[0109] In some embodiments, the second adhesive head includes a second movable portion and a second supporting portion, the second movable portion is used to attach the adhesive tape 200 to the pole lug 111, the second supporting portion is used to support the pole lug 111, the second supporting portion is connected to the second movable portion, and the second movable portion is configured to be movable relative to the second supporting portion along the thickness direction Z of the conveyor belt 10. The second supporting portion is disposed on a side of the second movable portion away from the conveyor belt 10 along the width direction Y of the conveyor belt 10, and the second supporting portion protrudes from a side surface of the second movable portion along the thickness direction Z.

[0110] Exemplarily, the second movable part is a main functional component of the second glue sticking head for sticking glue to the pole lug 111. The second movable part is provided with a tape 200 on the surface of one side close to the conveyor belt 10 in the thickness direction Z. The second supporting part is used to support the pole lug 111 before the tape 200 is attached to the pole lug 111.

[0111] It can be understood that when the pole piece 110 is located on the conveyor belt 10, at least part of the pole ear 111 extends out of the conveyor belt 10 in the width direction Y of the conveyor belt 10, and the part of the ear extending out of the conveyor line is suspended in the air to facilitate the gluing device 20 to glue the pole ear 111.

[0112] During the process of the second adhesive head moving along the thickness direction Z and close to the pole lug 111, the second movable part and the second supporting part move synchronously. Since the second supporting part protrudes from the side surface of the second movable part close to the conveyor belt 10 along the thickness direction Z, the second supporting part will first contact the pole lug 111. After the second supporting member supports the pole lug 111, since the second movable part can move along the thickness direction Z of the conveyor belt 10 relative to the second supporting part, the second movable part can further move along the thickness direction Z and close to the pole lug 111 to attach the tape 200 to the pole lug 111.

[0113] The second supporting part can be directly connected to the second movable part, or can be restricted on the second movable part by other components. In some examples, the second movable part and the second supporting part are detachably connected to reduce the difficulty of maintenance.

[0114] Optionally, the second supporting portion may be, but is not limited to, a plate-like structure, a block-like structure, a columnar structure, or the like.

[0115] The above technical solution can support the pole ear 111 before gluing the pole ear 111 by introducing a second support member, thereby reducing the risk of tearing the pole ear 111 or causing attachment defects during the gluing process due to the drooping of the suspended part of the pole ear 111, thereby effectively improving the product yield.

[0116] In some embodiments, the electrode 110 processing equipment also includes a electrode unwinding device 40 and a slitting device 50. The electrode unwinding device 40 is arranged upstream of the conveyor belt 10, and the slitting device 50 is arranged between the electrode unwinding device 40 and the conveyor belt 10. The electrode unwinding device 40 is used to provide the electrode strip 100, and the slitting device 50 is used to slit the electrode strip 100 into multiple electrode sheets 110. The conveyor belt 10 is used to convey multiple electrode sheets 110.

[0117] Exemplarily, the pole piece 110 processing equipment may further include a die-cutting device, which is used to die-cut the pole piece strip 100 to form a plurality of pole ears 111 on the pole piece strip 100. The die-cutting device may be disposed upstream of the pole piece unwinding device 40, or between the pole piece unwinding device 40 and the slitting device 50.

[0118] The slitting device 50 is responsible for slitting the electrode strip 100 along the width direction Y of the conveyor belt 10 to divide the electrode strip 100 into a plurality of electrode pieces 110, which are conveyed on the conveyor line. The plurality of electrode pieces 110 may be, but is not limited to, two, three, four or more.

[0119] As an example, the slitting device 50 may include a driving motor and a blade, wherein the driving motor is used to drive the blade to move closer to or away from the pole piece strip 100, so that when the pole piece strip 100 needs to be slit, the blade is in contact with the pole piece strip 100; when the pole piece strip 100 does not need to be slit, the blade is separated from the pole piece strip 100. The blade may be, but is not limited to, a circular blade, a rectangular blade, or a triangular blade.

[0120] Optionally, the slitting device 50 may include two blades, which are respectively located on both sides of the pole piece strip 100 along the thickness direction Z.

[0121] The above technical solution first cuts the pole piece strip 100 into multiple pole pieces 110, and then glues the pole ears 111 of the multiple pole pieces 110 separately. Compared with directly gluing the multiple pole ears 111 on the entire pole piece strip 100, it can reduce the influence of pulling or pushing with a superimposed effect on the entire pole piece strip 100 caused by multiple gluing processes, which helps to improve product yield.

[0122] In some embodiments, the pole piece 110 processing equipment further includes a roller assembly 60, which is disposed between the pole piece unwinding device 40 and the slitting device 50. The roller assembly 60 includes a first roller body 61 and a second roller body 62, which are disposed along the thickness direction Z of the conveyor belt 10, and the roller assembly 60 is used to allow the pole piece strip 100 to pass between the first roller body 61 and the second roller body 62.

[0123] The roller assembly 60 can maintain the tension of the pole piece strip 100 and reduce the risk of affecting normal transportation due to the relaxation of the pole piece strip 100.

[0124] Optionally, the first roller body 61 and the second roller body 62 may be made of materials such as rubber, polyurethane or silicone, which can not only provide sufficient friction to adjust the tension but also reduce damage to the surface of the pole piece 110 .

[0125] In some embodiments, the pole piece 110 processing equipment also includes a transition table 70, which is arranged between the pole piece unwinding device 40 and the slitting device 50, and a side surface of the transition table 70 close to the slitting device 50 along the thickness direction Z of the conveyor belt 10 is used to support the pole piece strip 100.

[0126] Exemplarily, the transition table 70 is used to carry part of the electrode strip 100. The slitting device 50 is located between the transition table 70 and the conveyor belt 10. During the conveying process of the electrode strip 100, after the electrode strip 100 passes through the side surface of the transition table 70 close to the slitting device 50 along the thickness direction Z of the conveyor belt 10 and reaches the conveyor belt 10, the slitting device 50 slits the electrode strip 100. The electrode 110 formed after slitting is located on the conveyor belt 10 and continues to be conveyed along the conveying direction X, so that the subsequent gluing device 20 can glue its pole ear 111. The electrode strip 100 located on the transition table 70 continues to be conveyed close to the conveyor belt 10 so that a part of the electrode strip 100 is located on the conveyor belt 10, and then the slitting device 50 slits the electrode strip 100 again, and so on.

[0127] Optionally, the transition platform 70 may be, but is not limited to, a plate-like structure, a block-like structure, a columnar structure, or the like.

[0128] The above technical solution can improve the stability of the pole piece strip 100 during the slitting process of the pole piece strip 100 by introducing the transition table 70, thereby improving the slitting quality of the pole piece 110, and further helping to improve the overall product yield of the pole piece 110.

[0129] In some examples, there is a certain gap between the transition platform 70 and the conveyor belt 10 , and the gap can avoid the cutter of the slitting device 50 .

[0130] In some examples, a surface of the transition table 70 on one side close to the slitting device 50 along the thickness direction Z of the conveyor belt 10 is flush with the surface of the conveyor belt 10 used to convey the pole piece 110 , which can further improve the stability of the pole piece 110 during transportation.

[0131] In some embodiments, the transition stage 70 is disposed between the roller assembly 60 and the slitting device 50 .

[0132] According to some embodiments of the present application, the present application also provides a battery production line, including a pole piece 110 processing device according to any of the above schemes.

[0133] In order to better understand the pole piece 110 processing equipment provided in the embodiment of the present application, based on the same inventive concept, an embodiment of the pole piece 110 processing equipment in actual application is provided here for illustration.

[0134] The embodiment of the present application provides a processing device for a pole piece 110, which includes a conveyor belt 10, a gluing device 20 and a moving device 30. The conveyor belt 10 is used to convey the pole piece 110, and the gluing device 20 is used to glue the pole ear 111 of the pole piece 110. The moving device 30 is connected to the gluing device 20, and the moving device 30 is used to drive the gluing device 20 to move in a direction parallel to the conveying direction X of the conveyor belt 10. The gluing device 20 includes a first gluing component 21 and a second gluing component 22, which are arranged opposite to each other along the thickness direction Z of the conveyor belt 10, and are respectively used to glue the two opposite sides of the pole ear 111 along the thickness direction Z.

[0135] The moving device 30 includes a first moving part 31 and a second moving part 32. The first moving part 31 includes a first rail 311 and a second rail 312. The first rail 311 and the second rail 312 are respectively arranged on both sides of the conveyor belt 10 in a direction intersecting with the conveying direction X. The first rail 311 and the second rail 312 are both extended along the conveying direction X. The second moving part 32 is movably connected to the first rail 311 and the second rail 312, and the second moving part 32 is movable on the first rail 311 and the second rail 312 in a direction parallel to the conveying direction X. The glue sticking device 20 is connected to the second moving part 32.

[0136] During the process of gluing the pole piece 111 by the pole piece 110 processing equipment of the above technical solution, while the conveyor belt 10 conveys the pole piece 110, the moving device 30 drives the gluing device 20 to move synchronously with the pole piece 110, so that the gluing device 20 remains relatively still with the pole piece 110 in the conveying direction X, and the gluing device 20 glues the pole piece 111 while moving along the conveying direction X. During the entire process of gluing the pole piece 111, the conveyor belt 10 does not need to pause and wait, which can shorten the time of the entire pole piece 111 gluing process, thereby effectively improving the production efficiency of the pole piece 110.
