Description

Technical Field

[0001] The utility model relates to the technical field of thermal composite equipment, in particular to a cleaning device and a thermal composite rolling roller. Background Art

[0002] Hot-composite lamination is a core step in the lithium-ion battery lamination process, and its quality is directly linked to the strength of the battery cells and the stability of the lamination process. However, during this process, the surface of the laminating roller is easily contaminated with dust particles, especially large particles. These particles not only threaten the flatness of the positive electrode sheet and the integrity of the separator, but can also cause battery performance degradation and even safety hazards. To address this issue, two contact cleaning methods, scrapers and sticky rollers, have traditionally been used, but both have significant drawbacks.

[0003] First, scraper cleaning relies on direct friction between a high-strength plastic scraper and the metal roller surface to remove dust from the roller. However, long-term use of this method can cause the scraper edge to gradually deform due to heat and pressure, forming gaps, severely weakening its cleaning effectiveness and shortening its service life. More seriously, the continuous friction can also damage the surface finish of the laminating roller, further affecting lamination quality and process stability.

[0004] Secondly, while sticky rollers can handle some dust, they rely primarily on a sticky substance to capture dust. This significantly reduces their cleaning effectiveness for dust particles that cling strongly to the roller surface, potentially exacerbating surface contamination. These difficult-to-remove dust particles gradually accumulate, forming a solid, colloid-like substance that not only reduces the roller's non-stick properties but also hinders subsequent cleaning efforts, creating a vicious cycle. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art described above, the present invention provides a cleaning device and a thermal composite laminating roller, which can solve the problem of unstable cleaning of dust particles on the roller surface of the thermal composite laminating roller.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A cleaning device for a hot composite laminating roller, comprising:

[0008] Scanning structure;

[0009] The cleaning structure includes a negative pressure chamber component and an ultrasonic emitting component, the negative pressure chamber component has a negative pressure suction port and a negative pressure convection port, the negative pressure suction port faces the rolling roller, and the ultrasonic emitting component has an ultrasonic emitting port facing the rolling roller.

[0010] By adopting the above scheme, a scanning structure is used to scan the roller surface of the hot composite rolling roller to identify dust particles or other attachments (hereinafter collectively referred to as dust particles) on the roller surface. The negative pressure chamber component absorbs the dust particles, and the negative pressure convection port facilitates the airflow at the corresponding negative pressure suction port. The ultrasonic emission component acts on the dust particles that cannot be sucked away by the negative pressure chamber component for targeted debonding, thereby achieving non-contact cleaning of the roller surface, and can also clean dust particles with strong adhesion, thereby keeping the roller surface of the hot composite rolling roller clean, reducing equipment maintenance requirements, and improving the production yield of lithium batteries. At the same time, a more efficient and longer-lasting cleaning effect is achieved, which has significant improvement significance for the lithium battery manufacturing industry.

[0011] Furthermore, the ultrasonic emitting assembly includes a frequency conversion structure and an air supply device, the frequency conversion structure is arranged between the rolling roller and the air supply device, and the air outlet of the air supply device is arranged toward the ultrasonic emitting port.

[0012] By adopting the above solution, the variable frequency structure allows for dynamic adjustment of the ultrasonic frequency, thereby using different resonant frequencies for dust particles of different sizes and types. When the ultrasonic frequency is consistent with the resonant frequency of the dust, the ultrasonic energy can act more concentratedly on the dust particles, destroying their adhesion to the surface of the rolling roller, making it easier for large dust molecules to fall off the roller surface, thereby increasing the applicability and flexibility of the cleaning device. At the same time, the airflow generated by the air supply device can help blow away loose dust particles, further improving cleaning efficiency. And by precisely controlling the frequency of the ultrasonic wave, unnecessary energy waste can be avoided, while reducing noise problems caused by excessively high or low frequencies. It not only saves energy, but also helps create a more comfortable working environment.

[0013] Furthermore, the frequency conversion structure includes a motor, an eccentric shaft and a piston assembly, the piston assembly includes a piston and a piston cylinder, the motor is transmission-connected to the eccentric shaft, the piston is transmission-connected to the eccentric shaft to drive the piston to reciprocate in the piston cylinder, and the piston cylinder is connected to the air supply path of the air supply device.

[0014] With this solution, the motor rotates the eccentric shaft, which in turn drives the piston in reciprocating motion within the cylinder. This process generates stable ultrasonic vibrations. The close fit between the piston and cylinder ensures efficient conversion of vibration energy, generating high-quality ultrasonic waves. By adjusting the motor speed, the frequency of the ultrasonic waves can be adjusted as needed, achieving a more precise cleaning effect.

[0015] Furthermore, the frequency conversion structure is provided with a plurality of piston assemblies, and the piston assemblies also include elastic parts, wherein each of the pistons is installed in the corresponding piston cylinder, and each of the pistons is fixedly connected to the corresponding elastic part. The frequency conversion structure also includes a transmission plate, the side wall of the eccentric shaft is in contact with the transmission plate, and the transmission plate is in contact with all the elastic parts.

[0016] By adopting the above solution, through the provision of elastic members and transmission plates, multiple piston assemblies are synchronously driven via a single eccentric shaft, significantly reducing the cost, assembly tolerance, and failure rate issues associated with traditional, complex mechanical transmission mechanisms. Furthermore, the provision of multiple piston assemblies allows ultrasonic waves to cover a wider area, ensuring consistent cleaning of the entire surface of the thermally composite laminating roller, avoiding blind spots and improving comprehensiveness and consistency. The provision of a transmission plate enables a single eccentric shaft to drive multiple piston assemblies simultaneously, thereby simplifying the transmission structure, reducing production costs, and increasing service life.

[0017] Furthermore, multiple groups of the piston assemblies are arranged along the length direction of the ultrasonic emission port, and / or multiple groups of the piston assemblies are arranged along the air supply direction of the air supply device.

[0018] By adopting the above solution and arranging multiple groups of piston assemblies in the length direction of the ultrasonic emission port, it is ensured that ultrasonic energy is efficiently generated in the entire length direction, thereby improving the cleaning effect.

[0019] Multiple sets of piston assemblies are arranged along the air supply direction of the air supply device, which can form a synergistic effect with the air flow of the air supply device. The ultrasonic vibration and the propulsion of the air flow act together on the dust, accelerating the loosening and removal of the dust and significantly improving the cleaning efficiency.

[0020] Furthermore, the frequency conversion structure is provided with two groups, and is respectively provided on both sides of the ultrasonic emission port.

[0021] By adopting the above solution, two sets of frequency conversion structures are respectively arranged on both sides of the ultrasonic emission port, which can more finely adjust the frequency and intensity of the ultrasonic wave to adapt to different types of dust.

[0022] In addition, if one set of frequency conversion structures fails, the other set can still work, providing backup for the cleaning process and ensuring the continuity and stability of production.

[0023] Furthermore, the negative pressure chamber components are provided in two groups, and the ultrasonic emitting component is provided between the two groups of negative pressure chamber components.

[0024] By adopting the above scheme, two groups of negative pressure chamber assemblies are set, and the ultrasonic emitting assembly is arranged between the two groups of negative pressure chamber assemblies. During the rotation of the hot composite rolling roller, the dust particles with weak adhesion are first removed through the first negative pressure chamber assembly, and then the dust particles with strong adhesion are debonded by the ultrasonic emitting assembly. Affected by the air supply device in the ultrasonic emitting assembly, the dust particles are blown away from the roller surface. Regardless of whether the blown away dust particles move upward or downward, they will be collected by the two groups of negative pressure chamber assemblies arranged on both sides of the ultrasonic emitting assembly. Afterwards, the dust particles that are not blown away by the air supply device will have their adhesion greatly reduced after passing through the ultrasonic emitting assembly. When passing through the second group of negative pressure chamber assemblies, the adhesion of the dust particles will be greatly reduced, and they will also be collected by the negative pressure chamber assembly, thereby debonding from the hot composite rolling roller.

[0025] Furthermore, the scanning structure includes a camera and a light source, the camera is arranged toward the rolling roller, and the light source is arranged toward the camera shooting area.

[0026] By adopting this solution, the camera and light source combination provides clear images, ensuring accurate inspection of the roller surface condition. The light source setting improves image contrast, allowing the camera to more clearly capture tiny foreign matter such as dust, thereby achieving high-precision surface quality inspection.

[0027] The information detected by the camera can be fed back to the control system to achieve closed-loop control. For example, if the control system detects an increase in dust in a specific location, it can adjust the ultrasonic frequency or the suction power of the negative pressure suction port accordingly to optimize the cleaning effect.

[0028] Furthermore, the camera is a line scan camera or an industrial camera.

[0029] By adopting the above solution, line scan cameras, due to their high-speed scanning characteristics, are well-suited for surface inspection of continuously moving objects, such as the rapidly rotating hot-compound laminating rollers. They can capture images at very fast speeds and monitor the cleanliness of the roller surface in real time, ensuring that any dust or impurities are quickly detected.

[0030] Industrial cameras typically have high resolution and can capture tiny dust particles or surface defects, allowing them to accurately locate dust particles and analyze cleaning needs.

[0031] The present utility model also provides a thermal composite laminating roller, comprising a first thermal composite laminating roller and a second thermal composite laminating roller, wherein the rotating shaft of the first thermal composite laminating roller and the rotating shaft of the second thermal composite laminating roller are arranged parallel to each other, and a gap is provided between the rotating shaft of the first thermal composite laminating roller and the second thermal composite laminating roller, the first thermal composite laminating roller is provided with a cleaning device as described above facing its roller surface, and / or the second thermal composite laminating roller is provided with a cleaning device as described above facing its roller surface.

[0032] By adopting the above scheme, the hot composite laminating roller is combined with the cleaning device, which can provide non-contact cleaning for the first hot composite laminating roller and the second hot composite laminating roller, and can also clean dust particles with strong adhesion to ensure the cleaning effect.

[0033] In summary, the cleaning device provided by the present invention has the following technical effects:

[0034] 1. The roller surface is cleaned by ultrasonic and negative pressure vacuuming, avoiding the wear and contamination of the roller surface caused by traditional contact cleaning, and maintaining the smoothness and non-stick performance of the roller surface.

[0035] 2. The ultrasonic emission component can debond highly sticky dust particles, thus ensuring the complete cleaning of the roller surface.

[0036] 3. By maintaining the cleanliness of the roller surface, the maintenance requirements of the equipment are reduced, and the equipment downtime and maintenance costs caused by insufficient cleaning are reduced.

[0037] 4. A clean roller surface helps improve the production yield of lithium batteries, avoids problems such as positive electrode plate depression or diaphragm puncture caused by dust particles, and thus reduces the production of unqualified products.

[0038] 5. More efficient and stable cleaning effects can significantly reduce cleaning pauses, thereby increasing equipment utilization and further improving the production efficiency of the entire production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] See Figure 1-Figure 3 As shown, the utility model discloses a cleaning device, which is mainly used for a hot composite laminating roller 3. The cleaning device includes a scanning structure 1 and a cleaning structure 2. The cleaning structure 2 includes a negative pressure chamber component 21 and an ultrasonic emitting component. The negative pressure chamber component 21 has a negative pressure suction port 211 and a negative pressure convection port 212. The negative pressure suction port 211 faces the laminating roller 3. The ultrasonic emitting component has an ultrasonic emitting port 221 facing the laminating roller 3.

[0049] Specifically, the scanning structure 1 is mainly used to identify whether there are dust particles or other attachments (hereinafter collectively referred to as dust particles) on the roller surface of the hot composite laminating roller 3. The scanning structure 1 can be a line scan camera, an industrial camera or other visual recognition equipment, as long as it can identify the dust on the roller surface. The ultrasonic emitting component has an ultrasonic emitting port 221 set towards the laminating roller 3. The ultrasonic wave emitted by the ultrasonic emitting component acts on the roller surface of the laminating roller 3 through the ultrasonic emitting port 221 to debond the dust particles on the roller surface of the laminating roller 3. The size, shape and number of the ultrasonic emitting port 221 can be selected according to design requirements and are not limited here. The ultrasonic emitting component can be an ultrasonic transmitter or other ultrasonic emitting equipment or components. The negative pressure chamber component 21 has a negative pressure suction port 211 facing the laminating roller 3, which is used to absorb dust particles on the roller surface, thereby realizing non-contact removal of dust particles on the roller surface. The negative pressure convection port 212 is used to discharge the air extracted to maintain the negative pressure state in the negative pressure chamber component. Among them, the size, shape and number of the negative pressure suction port 211 can be set according to actual needs and are not limited here. The negative pressure chamber assembly 21 is specifically a cavity and a power device that puts the cavity in a negative pressure state. The corresponding exhaust port of the power device is connected to the negative pressure convection port 212 or the power device is assembled at the negative pressure convection port 212 and is sealed with the negative pressure convection port 212, which can also achieve the state of maintaining the negative pressure in the negative pressure chamber assembly. The power device can specifically be a cavity with a negative pressure pump to form the negative pressure chamber assembly 21. Of course, other structures and devices can also be used to form the negative pressure chamber assembly 21, which is not limited here.

[0050] In this embodiment, the negative pressure suction port 211 and the ultrasonic emission port 221 are both arranged parallel to the axial direction of the rolling roller 3. This ensures that the opening area of the negative pressure suction port 211 and the ultrasonic emission port 221 is minimized while ensuring that they cover the rolling roller 3. Two negative pressure suction ports 211 are provided, both located close to the rolling roller 3 to enhance dust particle capture. Furthermore, the two negative pressure suction ports 211 are positioned at the same distance from the roller surface of the rolling roller 3, ensuring that both negative pressure suction ports 211 provide equally effective cleaning results.

[0051] It should be noted that the scanning structure 1 in the above structure can only be used to monitor whether there are dust particles on the roller surface, and is not used as the only reference for starting and adjusting the operation of the cleaning structure 2. Therefore, the above structure does not rely on software for implementation.

[0052] In this embodiment, see Figure 1 and Figure 2As shown, the ultrasonic emitting assembly includes a frequency conversion structure and an air supply device. The frequency conversion structure is positioned between the rolling roller 3 and the air supply device, with the air outlet of the air supply device facing the ultrasonic emitting port 221. Specifically, the frequency conversion structure is capable of generating ultrasonic waves and adjusting the ultrasonic frequency. The frequency conversion structure can be an ultrasonic transmitter with frequency modulation capabilities or another mechanical frequency modulation structure. The air supply device's sealed end is positioned toward the ultrasonic emitting port 221, continuously supplying air to the roller surface, helping to remove dust particles from the roller surface.

[0053] Furthermore, the variable frequency structure allows for dynamic adjustment of the ultrasonic frequency, thereby using different resonant frequencies for dust particles of different sizes and types. When the ultrasonic frequency matches the resonant frequency of the dust, the ultrasonic energy can act more concentratedly on the dust particles, breaking their adhesion to the surface of the roller 3 and making it easier for large dust particles to fall off the roller surface, thereby increasing the applicability and flexibility of the cleaning device. Furthermore, by precisely controlling the ultrasonic frequency, unnecessary energy waste can be avoided, while also reducing noise issues caused by excessively high or low frequencies. This not only saves energy but also helps create a more comfortable working environment.

[0054] See Figure 1 and Figure 3 As shown, in some embodiments, the frequency conversion structure includes a motor 222, an eccentric shaft 223 and a piston assembly, the piston assembly includes a piston 224 and a piston cylinder 225, the motor 222 is transmission-connected to the eccentric shaft 223, the piston 224 is transmission-connected to the eccentric shaft 223 to drive the piston 224 to reciprocate in the piston cylinder 225, and the piston cylinder 225 is connected to the air supply path of the air supply device.

[0055] Specifically, the motor 222 is connected to the eccentric shaft 223 in a transmission manner, and the eccentric shaft 223 drives the piston 224 to reciprocate within the piston cylinder 225. The motor 222 and the eccentric shaft 223 can be coaxially driven to ensure a high frequency rotation frequency of the eccentric shaft 223. Alternatively, the motor 222 and the eccentric shaft 223 can be connected to each other through a gearbox to ensure multi-dimensional adjustment of the rotation frequency and output torque of the eccentric shaft 223. The transmission connection between the eccentric shaft 223 and the piston 224 can be specifically connected through a universal joint, similar to the transmission assembly of the engine piston 224, or other transmission structures can be used to enable the eccentric shaft 223 to drive the piston 224 to reciprocate within the piston cylinder 225. The piston cylinder 225 is provided with a through hole connected to the air supply path of the air supply device, thereby ensuring that the generated ultrasonic wave can pass through the ultrasonic emission port 221 and act on the roller surface.

[0056] See Figure 1 and Figure 3As shown, in this embodiment, the frequency conversion structure is provided with a plurality of piston assemblies, and the piston assembly further includes an elastic member 226, wherein each piston 224 is correspondingly installed in the piston cylinder 225 corresponding thereto, and each piston 224 is fixedly connected to the elastic member 226 corresponding thereto, and the frequency conversion structure further includes a transmission plate 227, and the side wall of the eccentric shaft 223 is in contact with the transmission plate 227, and the transmission plate 227 is in contact with all the elastic members 226.

[0057] See Figure 1 and Figure 3 As shown, specifically, when the cleaning device is provided with multiple sets of piston assemblies, in order to facilitate the transmission of the multiple sets of piston assemblies, an elastic member 226 is further provided in the piston assembly. The elastic member 226 is provided between the piston 224 and the transmission plate 227 to support the transmission plate 277 and to ensure that the transmission plate 227 always remains in contact with the roller surface. The elastic member 226 can be an elastic object such as a shrapnel or a spring, which is not limited here. In the multiple sets of piston assemblies, the piston 224, the piston cylinder 225 and the elastic member 226 are assembled and arranged in a one-to-one correspondence. During the rotation of the eccentric shaft 223, the transmission plate 227 is driven to move toward the direction of the piston cylinder 225, and under the action of the elastic member 226, the transmission plate 227 is pushed to always remain in contact with the axial surface of the eccentric shaft 223 to ensure that the movement distance and movement frequency of the piston 224 are the same, thereby ensuring the stability and adjustability of the generated ultrasonic frequency. Furthermore, the provision of multiple piston assemblies allows the ultrasonic waves to cover a wider area, ensuring a consistent cleaning effect across the entire surface of the thermal composite laminating roller 3, avoiding blind spots and improving comprehensiveness and consistency of cleaning. The provision of a transmission plate 227 enables a single eccentric shaft 223 to drive multiple piston assemblies to operate simultaneously, thereby simplifying the transmission structure, reducing production costs, and increasing service life.

[0058] See Figure 1 and Figure 3 As shown, in some embodiments, multiple groups of piston assemblies are arranged along the length direction of the ultrasonic emission port 221, and / or multiple groups of piston assemblies are arranged along the air supply direction of the air supply device.

[0059] When multiple piston assemblies are arranged in the length direction of the ultrasonic emission port 221, it is possible to ensure that ultrasonic energy is efficiently generated in the entire length direction, thereby improving the cleaning effect.

[0060] When multiple groups of piston assemblies are arranged along the air supply direction of the air supply device, they can enhance the synergistic effect with the airflow of the air supply device. The ultrasonic vibration and the propulsion of the airflow act together on the dust, accelerating the loosening and removal of the dust, and significantly improving the cleaning efficiency.

[0061] Users can adopt specific settings according to their needs. In this embodiment, multiple groups of piston assemblies are arranged along the length direction of the ultrasonic emission port 221, and two rows are arranged along the air supply direction of the air supply device, so as to take into account the efficient generation efficiency of ultrasonic waves and the synergistic effect formed by ultrasonic waves and airflow.

[0062] See Figure 1 and Figure 3 As shown, in some embodiments, two groups of frequency conversion structures are provided, and are respectively arranged on both sides of the ultrasonic emission port 221. Specifically, there are two groups of frequency conversion structures, and the two groups of frequency conversion structures are arranged relative to the ultrasonic emission port 221. The specific setting positions can be the left and right sides of the ultrasonic emission port 221, or the upper and lower sides, or the adjacent two sides. The specific setting form can be selected as needed. In this embodiment, the two groups of frequency conversion structures are arranged parallel to the length direction of the ultrasonic emission port 221, so as to ensure the frequency and intensity of the ultrasonic wave to adapt to different types of dust. In addition, if one group of frequency conversion structures fails, the other group can still work, providing a backup for the cleaning process and ensuring the continuity and stability of production.

[0063] See Figure 1 As shown, in this embodiment, there are two groups of negative pressure chamber assemblies 21, and the ultrasonic emitting assembly is arranged between the two groups of negative pressure chamber assemblies 21. The specific arrangement is that the ultrasonic emitting assembly is arranged between the two groups of negative pressure chamber assemblies 21 along the rotation direction of the laminating roller 3. During the rotation of the hot composite laminating roller 3, the dust particles with weak adhesion first pass through the first negative pressure chamber assembly 21 to be removed, and then the dust particles with strong adhesion are debonded by the ultrasonic emitting assembly. Under the influence of the air supply device in the ultrasonic emitting assembly, the dust particles are blown away from the roller surface. Whether the dust particles move upward or downward, they will be collected by the two groups of negative pressure chamber assemblies 21 arranged on both sides of the ultrasonic emitting assembly. After that, the dust particles that are not blown away by the air supply device will have their adhesion greatly reduced after passing through the ultrasonic emitting assembly. When passing through the second group of negative pressure chamber assemblies 21, due to the greatly reduced adhesion of the dust particles, they will also be collected by the negative pressure chamber assemblies 21, thereby debonding from the hot composite laminating roller 3.

[0064] Reference Figure 1 and Figure 3 As shown, in some embodiments, the scanning structure 1 includes a camera 11 and a light source 12 . The camera 11 is arranged toward the laminating roller 3 , and the light source 12 is arranged toward the shooting area of the camera 11 .

[0065] Specifically, the combination of the camera 11 and the light source 12 can provide a clear image, ensuring accurate detection of the surface condition of the rolling roller 3. The provision of the light source 12 can improve the image contrast, allowing the camera 11 to more clearly capture tiny foreign matter such as dust, thereby achieving high-precision surface quality detection.

[0066] In addition, the setting of camera 11 can provide a basis for closed-loop control. For example, the information detected by camera 11 can be fed back to the control system. When an increase in dust is detected at a specific location, the control system can adjust the ultrasonic frequency or the suction force of the negative pressure suction port 211 accordingly to optimize the cleaning effect.

[0067] In some embodiments, to expand the options for camera 11, camera 11 employs a line scan camera or an industrial camera. Line scan cameras, due to their high-speed scanning capabilities, are well-suited for inspecting the surfaces of continuously moving objects, such as the rapidly rotating hot-compound laminating roller 3. They can capture images at very high speeds, monitor the roller surface's cleanliness in real time, and ensure that any dust or impurities are quickly detected.

[0068] Industrial cameras typically have high resolution and can capture tiny dust particles or surface defects, allowing them to accurately locate dust particles and analyze cleaning needs.

[0069] In addition, line scan cameras or industrial cameras are easy to integrate with automated control systems. Image processing software can analyze the captured images, automatically trigger cleaning procedures or adjust cleaning parameters, and achieve intelligent closed-loop control.

[0070] See Figure 1 、 Figure 3 and Figure 4 As shown, the utility model also relates to a thermal composite laminating roller, comprising a first thermal composite laminating roller 31 and a second thermal composite laminating roller 32, the rotating shaft of the first thermal composite laminating roller 31 and the rotating shaft of the second thermal composite laminating roller 32 are arranged parallel to each other, and a gap is provided between the rotating shaft of the first thermal composite laminating roller 31 and the second thermal composite laminating roller 32, the first thermal composite laminating roller 31 is provided with a cleaning device as described above facing its roller surface, and / or the second thermal composite laminating roller 32 is provided with a cleaning device as described above facing its roller surface.
