Description

Technical Field

[0001] This application relates to the field of battery electrode production equipment technology, and in particular to battery electrode lead-in device and composite roll equipment. Background Technology

[0002] In the manufacturing process of battery electrodes, the rolling process is crucial to the quality and performance of the strip. For production lines that roll multiple strips in parallel, when changing rolls (loading new rolls) or dealing with strip breaks, it is necessary to simultaneously re-draw multiple strips through the rolls.

[0003] In related technologies, when changing material rolls or repairing broken tape, the equipment is usually stopped first, and then the tape is manually guided or spliced. This results in the inability to achieve continuous production, and manual roll changing or splicing poses safety hazards. Furthermore, it cannot guarantee consistent tension across multiple tapes, leading to unstable tension control, electrode deformation or breakage, and other problems that affect product quality.

The belt-threading assembly includes a drive wheel, a plurality of driven wheels, and a conveyor belt. The drive wheel and the driven wheels are rotatably mounted on the frame. The conveyor belt forms a closed conveying path through the wheels.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In related technologies, for production lines that produce multi-electrode sheets in parallel, when changing coils (loading new coils) or dealing with strip breaks, the equipment is usually stopped first, and then the strips are manually guided or spliced. This results in the inability to achieve continuous production, and manual coil changing or splicing poses safety hazards. Furthermore, it cannot guarantee consistent tension across multiple strips, leading to unstable tension control, electrode deformation or breakage, and other problems that affect product quality.

[0038] To address the aforementioned issues, this application provides a battery electrode lead-in device that can automatically lead and connect electrodes through a lead-in mechanism, and adjust the tension of multiple electrodes in real time through multiple tension adjustment mechanisms to ensure that the tension of multiple electrodes is equal, thereby avoiding process defects caused by inconsistent lead-in tension.

[0039] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0040] Figure 1 This is a schematic diagram of the structure of the battery electrode lead-in device shown in the embodiments of this application.

[0041] See Figure 1 This application provides a battery electrode sheet drawing device, including a frame 1, multiple unwinding devices 2, and a drawing mechanism 3. The frame 1 is provided with a converging area 10. The multiple unwinding devices 2 are disposed on the frame 1, and each unwinding device 2 includes an unwinding mechanism 20 and a tension adjusting mechanism 21. The tension adjusting mechanism 21 is disposed downstream of the unwinding mechanism 20 along the conveying direction of the material strip, and the tension adjusting mechanism 21 is used to adjust the tension of the material strip so that the tension of the multiple material strips transmitted to the converging area 10 is equal. The drawing mechanism 3 is disposed on the frame 1 and is used to draw the composite material strip formed by converging in the converging area 10 into the rolling device 4.

[0042] In this embodiment, the number of unwinding devices 2 can be set according to actual production needs, and this application does not limit this. Figure 1 The diagram exemplarily shows three unwinding devices 2 to unwind three rolls. The converging zone 10 can be positioned close to the rolling mill 4, allowing the composite strip formed after convergence in the converging zone 10 to be quickly drawn into the rolling mill 4. This composite strip is the strip formed after multiple strips are laminated together, for example... Figure 1 The three-in-one material strip shown in the image.

[0043] Each unwinding device 2 includes an unwinding mechanism 20 and a tension adjusting mechanism 21. The unwinding mechanism 20 includes an unwinding roller, which can be made of steel or aluminum alloy, with a hard chrome plated surface or a rubber coating to prevent scratching the inner core of the roll. The unwinding roller can be actively unwinding, relying on the traction force of subsequent processes to pull the roll; or it can be actively unwinding, driven by a servo motor to precisely control the unwinding speed. The tension adjusting mechanism 21 is located downstream of the unwinding mechanism 20 along the conveying direction of the strip, and can control the tension of the strip by adjusting the path length of the strip. The tension adjusting mechanisms 21 of multiple unwinding devices 2 independently control the tension of the strip they unwind, without interfering with each other; and each tension adjusting mechanism 21 can adjust the corresponding strip to the same target tension, so that the tension of the strips unwound by multiple unwinding devices 2 transmitted to the convergence area 10 is equal. This embodiment of the application also features an automatic belt guiding mechanism 3, which pulls the composite strip formed in the convergence zone 10 into the rolling mill device 4. Furthermore, it can automatically guide or splice the strip when changing rolls or handling broken strips. This achieves automatic belt guiding and splicing, and ensures synchronous unwinding of multiple strips, consistent tension control, and composite belt guiding, avoiding process defects caused by inconsistent belt tension.

[0044] As an optional embodiment, see Figure 1 and Figure 2 The tension adjustment mechanism 21 includes a swing roller assembly 210, which includes a swing roller 2100 and a driver 2101. The driver 2101 is connected to the swing roller 2100 and is used to adjust the swing angle of the swing roller 2100 to adjust the tension of the feeding belt of the swing roller 2100.

[0045] In this embodiment, the swing roller assembly 210 can dynamically adjust the path length of the material belt by changing the swing angle of the swing roller 2100, thereby controlling the tension of the material belt.

[0046] For example, the swing roller 2100 can be a roller that can swing around a fixed fulcrum, with the strip wrapping around the roller to form an "S" or "Ω" shaped wrapping path. The driver 2101 changes the position (angle) of the swing roller 2100 by pushing or rotating the swing arm, thereby adjusting the effective length of the strip. For example, when the swing roller 2100 swings upward, the strip path becomes longer and the tension decreases; when the swing roller 2100 swings downward, the strip path shortens and the tension increases.

[0047] In this embodiment, the driver 2101 can be a servo motor + ball screw driver. The servo motor converts the rotational motion into linear displacement through the ball screw, thereby driving the swing arm to swing. The driver 2101 can also be a pneumatic cylinder driver, which adjusts the cylinder pressure through a solenoid valve to drive the piston rod to move linearly and drive the swing roller to swing. This application does not limit this.

[0048] For example, in this embodiment of the application, the driver 2101 (low-friction cylinder) can also be controlled by an electrical proportional valve, and the air pressure can be adjusted as needed. The tension of the driver 2101 can be controlled according to different air pressures, thereby adjusting the swing angle of the swing roller 2100.

[0049] As a preferred embodiment, see Figure 1 and Figure 3 The tension adjustment mechanism 21 includes a tension roller assembly 211, which includes a tension roller 2110 and a tension detector 2111. The tension roller 2110 is located downstream of the swing roller 2100 along the conveying direction of the material belt. The tension detector 2111 is located on the tension roller 2110 and is used to detect the tension of the material belt on the tension roller 2110. The driver 2101 is also connected to the tension detector 2111 and is used to adjust the swing angle of the swing roller 2100 according to the tension detected by the tension detector 2111.

[0050] In this embodiment, the swing roller 2100 acts as an active adjustment unit, adjusting the length of the strip path between the unwinding mechanism 20 and the tension roller 2110 by changing its position. The tension detector 2111 is integrated on the tension roller to measure the actual tension value of the strip in real time.

[0051] The tension detector 2111 can be a strain gauge type tension sensor, in which a strain gauge is installed on the bearing seat of the tension roller 2110, and the tension of the material strip is converted into metal deformation, outputting an electrical signal. The tension detector 2111 can also be a piezomagnetic tension sensor, utilizing the magnetoelastic effect, where changes in tension alter the magnetic permeability, outputting a frequency signal. This application does not limit the specific type.

[0052] In this embodiment of the application, the unwinding device 2 may also include multiple guide rollers, through which the material strip passes, along with the swing roller assembly 210, the tension roller assembly 211, and converges into the converging area 10.

[0053] As an optional embodiment, see Figure 1 and Figure 4 The belt guiding mechanism 3 includes a belt guiding rod 30 and a belt threading assembly 31 mounted on the frame 1. The belt threading assembly 31 includes a drive wheel 310, multiple driven wheels 311, and a conveyor belt 312. The drive wheel 310 and the driven wheels 311 are rotatably mounted on the frame 1. The conveyor belt 312 forms a closed conveying path through the wheels. The belt guiding rod 30 is connected to the conveyor belt 312 and can guide the composite material belt formed by the convergence in the convergence area 10 to the rolling device 4 along the conveying path under the drive of the conveyor belt 312.

[0054] In this embodiment, the guide belt mechanism 3 is used to guide the composite strip formed by the convergence zone 10 to the rolling device 4, so that the rolling device 4 can roll the composite strip. When multiple strips converge in the convergence zone 10, the composite strip can be threaded onto the guide bar 30. The drive wheel 310 rotates, driving the conveyor belt 312 to move along the conveying path, thereby driving the guide bar 30 connected to the conveyor belt 312 to move synchronously. At the same time, the two pressure rollers of the rolling device 4 move away from each other, so that the composite strip threaded onto the guide bar 30 moves into the rolling device 4, realizing automatic guide belt pulling and guiding of the composite strip, avoiding manual entry into the equipment for threading and pulling operations, and reducing safety risks.

[0055] In this embodiment, the conveyor belt 312 can be a chain, and the drive wheel 310 can be a sprocket. The drive wheel 310 is driven to rotate by a hand-cranked roller. The driven wheel 311 can also be a sprocket. Multiple driven wheels 311 are spaced apart on the conveying path to achieve stable conveying of the pull rod 30.

[0056] As a preferred embodiment, see Figure 1 The belt guiding mechanism 3 also includes a first adjusting component 32, which is disposed on the conveyor belt 312 and is used to adjust the tension of the conveyor belt 312.

[0057] In this embodiment, when the contact between the conveyor belt 312 and each wheel is too tight or too loose, the tension of the conveyor belt 312 can be adjusted by the first adjusting component 32 to achieve stable conveying of the composite material belt, improve electrode production efficiency, and reduce safety risks.

[0058] As a preferred embodiment, see Figure 1 The belt guiding mechanism also includes a second adjusting component 33, which is located on the electrode rolling path and is used to adjust the angle of the composite strip before entering the rolling device 4, and / or to adjust the angle of the composite strip after being rolled by the rolling device 4.

[0059] In this embodiment, the second adjustment component 33 can be disposed between the converging area 10 and the rolling device 4, for adjusting the angle of the composite strip before entering the rolling device 4; and / or, the second adjustment component 33 can be disposed downstream of the rolling device 4, for adjusting the angle of the composite strip after being rolled by the rolling device 4. The second adjustment component 33 may include a slide and a tensioning wheel disposed on the slide. The tensioning wheel can move along the slide to press or release the composite strip, thereby adjusting the angle of the composite strip.

[0060] As an optional embodiment, see Figure 1 The belt guiding device also includes a guide roller 5, which is located in the converging area 10 and is used to gather the belts unwound by multiple unwinding devices 2 to form a composite belt.

[0061] In this embodiment, a guide roller 5 is provided in the convergence area 10, which can bond multiple material strips together with adhesive tape and then continue to transport them through the guide roller 5.

[0062] As an optional embodiment, see Figure 1 The belt guiding device also includes a heating roller mechanism 6 mounted on the frame 1. The heating roller mechanism 6 is located downstream of the convergence zone 10 along the belt conveying direction and is used to heat the composite belt after convergence.

[0063] In this embodiment, the heating roller mechanism 6 may include a hollow roller body made of stainless steel or alloy steel. The roller body surface is plated with hard chrome or ceramic coating to improve wear resistance and thermal conductivity. Heating elements and heat transfer medium channels are integrated inside the roller body. A motor drives the roller body to rotate, achieving uniform heating of the converged composite strip. The heating elements may be resistance wires (such as nickel-chromium alloy), which directly generate heat when energized. The heat transfer medium channels may be circulating heat transfer oil or steam to transfer heat.

[0064] As an optional embodiment, see Figure 1 The belt guiding device also includes a pre-compression mechanism 7 disposed on the frame 1. The pre-compression mechanism 7 is disposed between the convergence zone 10 and the roll device 4 along the belt conveying direction, and the pre-compression mechanism 7 is used to pre-compress the converged composite belt.

[0065] In this embodiment, the pre-compression mechanism 7 may include two pre-compression rollers that are arranged opposite to each other and can move closer or further apart. When the two pre-compression rollers are far apart, the converged composite strip can smoothly enter the gap between the two rollers. When the two rollers are close together, they pre-compress the converged composite strip, which can initially compact the active layer of the electrode, improve material density, and maintain the consistency of the thickness of multiple electrodes.

[0066] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a composite roll equipment and corresponding embodiments.

[0067] See Figure 1 This application embodiment also provides a composite roll equipment, including the aforementioned belt guiding device and a roll device 4 disposed on the frame 1. The roll device 4 is disposed downstream of the convergence area 10 of the belt guiding device along the belt conveying direction and is used to roll the converged composite belt.

[0068] In this embodiment, the rolling device 4 may include two oppositely arranged rolling rolls that can move closer to or further away from each other. When the two rolling rolls move further away from each other, the converged composite strip can smoothly enter the gap between the two rolling rolls. When the two rolling rolls move closer to each other, they roll the converged composite strip.

[0069] The guide belt device enables synchronous unwinding of multiple strips, consistent tension control, and composite guide belt operation. The strips are then guided to the rolling mill 4 to be rolled into the final product.
