Description

Technical Field

[0001] The present application relates to the technical field of diaphragm preparation devices, and in particular to a cleaning device and a coating system. Background Art

[0002] During the diaphragm production process, the diaphragm needs to be transported to the bottom of the nozzle of the coating device through a roller, and the slurry is sprayed on the diaphragm by the nozzle. The roller in contact with the diaphragm needs to be kept clean. If the slurry adheres to the roller surface, it will cause scratches and coating leakage on the diaphragm, affecting the quality of the diaphragm.

[0003] At present, most rollers are cleaned manually or by wiping the roller surface with a brush. These cleaning methods often have problems such as difficulty in cleaning, low efficiency, or easy damage to the roller surface. Utility Model Content

[0004] Based on the above-mentioned deficiencies, the present application provides a cleaning device and a coating system to improve the cleaning problem of the roller in the related art.

[0005] This application is implemented as follows:

[0006] In the first aspect, the example of the present application provides a cleaning device, including a cleaning mechanism and a moving mechanism. The cleaning mechanism includes a cleaning block, which has a cleaning side facing the roller to be cleaned along a first direction; an adsorption flow channel is provided along the circumferential edge of the cleaning side, and a flexible pad is provided on the outer wall of the adsorption flow channel for contacting with the roller surface of the roller; a dry ice nozzle is provided in the middle of the cleaning side; along the first direction, the protruding height of the dry ice nozzle does not exceed the protruding height of the adsorption flow channel, so that a gap is formed between the dry ice nozzle and the roller surface when the adsorption flow channel contacts with the roller surface; the cleaning block is connected to the moving mechanism, and the moving mechanism is used to drive the cleaning block to move along the axial direction of the roller.

[0007] In the above implementation process, the dry ice nozzle sprays dry ice onto the roller surface of the roller to knock off the slurry attachments deposited on the roller surface; the adsorption flow channel arranged around the dry ice nozzle is in contact with the roller surface of the roller, and the adsorption flow channel can adsorb the slurry attachments knocked off by the dry ice nozzle. The dry ice nozzle is used to spray dry ice to knock off the slurry attachments, and the dry ice sprayed by the dry ice nozzle will not contaminate the roller. The moving mechanism drives the cleaning block to move along the axial direction of the roller, and can clean different positions of the roller along its axial direction. Since a flexible pad is provided at the position where the adsorption flow channel contacts the roller, the cleaning block will not scratch the roller surface when the moving mechanism drives the cleaning block to move along the axial direction of the roller.

[0008] In combination with the first aspect, in an optional embodiment, the adsorption flow channel has an inner wall close to the dry ice nozzle and an outer wall close to the cleaning side edge, and along the first direction, the protruding height of the inner wall is smaller than the protruding height of the outer wall.

[0009] In the above implementation process, along the first direction, the protruding height of the inner wall of the adsorption flow channel close to the dry ice nozzle is smaller than the protruding height of the outer wall close to the cleaning side edge. When cleaning, the outer wall of the adsorption flow channel fits with the roller surface of the roller, and there is a certain gap between the inner wall and the roller surface of the roller, so that the slurry attachment knocked off by the dry ice nozzle can be sucked into the adsorption flow channel from the gap and then discharged through the adsorption flow channel.

[0010] In combination with the first aspect, in an optional embodiment, the flexible pad is arranged on the outer side wall.

[0011] In the above implementation process, the flexible pad is arranged on the outer side wall, and when the outer side wall contacts the roller surface of the roller, the outer side wall of the adsorption channel can be prevented from scratching the roller surface of the roller.

[0012] In combination with the first aspect, in an optional embodiment, the moving mechanism includes a fixed rod, a screw rod and a moving block, and both ends of the fixed rod and the screw rod are connected to the fixed block; the moving block is threadedly connected to the screw rod, the moving block is slidingly connected to the fixed rod, and the cleaning block is connected to the moving block.

[0013] In the above implementation process, the moving block is simultaneously threadedly connected to the screw and slidably connected to the guide rod. When the screw rotates, the moving block can move along the axial direction of the screw, thereby driving the cleaning block to move.

[0014] In combination with the first aspect, in an optional implementation, the cleaning device further includes a telescopic mechanism, the cleaning block is connected to the moving block via the telescopic mechanism, and the telescopic mechanism is used to drive the cleaning block to move along the first direction.

[0015] In the above implementation process, a telescopic mechanism is provided between the cleaning block and the moving block. When the roller needs to be cleaned, the telescopic mechanism can be used to drive the cleaning block to move toward the roller so that the adsorption channel at the cleaning block fits with the roller surface of the roller. When the roller does not need to be cleaned, the telescopic mechanism is used to drive the cleaning block to move away from the roller so that the adsorption channel is separated from the roller surface, thereby reducing the influence of the cleaning block on the roller operation and increasing the service life of the cleaning block.

[0016] In combination with the first aspect, in an optional implementation, the telescopic mechanism includes a cylinder, and an output end of the cylinder is connected to the cleaning block.

[0017] In the above implementation process, the output end of the cylinder is connected to the cleaning block, and the cylinder can be used to push the cleaning block to move in the direction close to the roller surface of the roller, so that the adsorption channel fits with the roller surface of the roller.

[0018] In combination with the first aspect, in an optional embodiment, the cleaning device also includes a control mechanism, which includes a camera and a controller; the camera is arranged on a fixed block, and the camera and the cylinder are both connected to the controller signal, and the camera is used to send a signal to the controller when it identifies that there is slurry attachment on the roller, and the controller receives the signal to control the cylinder to start, so as to drive the cleaning block to move, so that the adsorption flow channel fits with the roller surface of the roller.

[0019] In the above implementation process, a camera is set at the fixed block, and the camera can be used to shoot the roller surface of the roller to determine whether there is slurry attached to the roller surface. When the camera recognizes that there is slurry attached to the roller surface, the camera sends a signal to the controller. After receiving the signal sent by the camera, the controller automatically controls the cylinder to start, so that the cylinder drives the cleaning block to move toward the roller, so that the adsorption flow channel fits with the roller surface, thereby improving the cleaning efficiency of the cleaning device.

[0020] In combination with the first aspect, in an optional embodiment, the cleaning mechanism also includes a dry ice storage box and an adsorbent storage box, which are arranged on the side of the fixed block away from the movable block, and a dry ice compressor is arranged in the dry ice storage box; a first channel and a second channel are arranged in the internal interval of the fixed rod, the dry ice delivery pipe passes through the first channel to be connected to the dry ice nozzle and the dry ice compressor, and the adsorption pipe passes through the second channel to be connected to the adsorption flow channel and the adsorbent storage box.

[0021] In the above implementation process, a first channel and a second channel are provided at intervals inside the fixed rod, and the dry ice delivery pipe can be connected to the dry ice nozzle located at the moving block and the dry ice storage box located outside the fixed block through the first channel, and the adsorption pipe can be connected to the adsorption flow channel located at the moving block and the adsorbent storage box located outside the fixed block through the second channel. Fixing the dry ice delivery pipe and the adsorption pipe by the fixed rod can improve the cleanliness of the cleaning device. A dry ice compressor is provided in the dry ice storage box, which can transport the compressed dry ice along the dry ice delivery pipe to the dry ice nozzle, thereby improving the transportation efficiency.

[0022] In combination with the first aspect, in an optional implementation, the dry ice delivery tube and the adsorption tube are both shrinkable bellows.

[0023] In the above implementation process, the dry ice delivery tube and the adsorption tube are both configured as retractable bellows, and the lengths of the dry ice delivery tube and the adsorption tube can be changed accordingly with the movement of the moving block.

[0024] In the second aspect, the example of the present application provides a coating system, including a frame, a coating device and the cleaning device provided in the first aspect. The coating device is arranged on the frame; the coating device includes a nozzle and a roller, and the nozzle is arranged above the roller; the moving mechanism in the cleaning device is arranged on the frame, and the moving mechanism is used to drive the cleaning block to move along the axial direction of the roller.

[0025] In the above implementation process, the nozzle of the coating device can spray slurry onto the diaphragm located under the roller. When the nozzle sprays the slurry onto the diaphragm, part of the slurry will splash onto the roller surface of the roller. As the coating proceeds, a large amount of slurry attachments will adhere to the roller surface of the roller. The slurry attachments contain particulate matter, which can easily scratch the diaphragm when the roller contacts the diaphragm, affecting the quality of the diaphragm. The coating system provided in the example of the present application is provided with a cleaning device, and the dry ice nozzle in the cleaning device can spray dry ice onto the roller surface of the roller to knock off the slurry attachments attached to the roller surface of the roller, and at the same time, the adsorption flow channel surrounding the dry ice nozzle can fit with the roller surface of the roller to adsorb the slurry attachments knocked off by the dry ice nozzle. The moving mechanism can drive the cleaning block to move along the axial direction of the roller, and can clean the roller at different positions along its axial direction. Since a flexible pad is provided at the position where the adsorption flow channel contacts the roller, when the moving mechanism drives the cleaning block to move along the axial direction of the roller, the cleaning block will not scratch the roller surface of the roller, thereby further improving the coating quality.

DETAILED DESCRIPTION

[0034] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions.

[0036] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] In the description of the embodiments of the present application, the orientation or position relationship indicated by technical terms such as "middle", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "bottom", and "inside" are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the embodiments of the present application.

[0039] When the coating system 100 is used to coat the diaphragm, a portion of the slurry sprayed from the nozzle 21 will splash onto the roller 22. As the coating progresses, more slurry attachments will adhere to the roller surface of the roller 22. The granular powder in the slurry attachments gradually accumulates to form hard lumps, which are easy to scratch the diaphragm when the roller 22 contacts the diaphragm, affecting the quality of the diaphragm.

[0040] In order to improve the quality of the diaphragm, a manual wiping method is generally used to clean the slurry attachment on the surface of the roller 22. However, when manually wiping the roller, the roller 22 needs to be stopped, and the efficiency of manually wiping the roller 22 is low.

[0041] In order to improve the cleaning efficiency of the roller 22, a cleaning brush is tried to brush the roller surface of the roller 22 back and forth. However, when the cleaning brush is used to contact the roller surface of the roller 22 to brush away the slurry attachment, the cleaning brush is likely to damage the roller surface of the roller 22, and when the roller 22 is subsequently used to apply the slurry, it is likely to cause uneven coating, which affects the quality of the separator.

[0042] Therefore, the present application further improves the coating system 100, so as to improve the cleaning efficiency of the roller 22 and reduce the damage to the roller 22 to a certain extent. In order to make the purpose, technical solution and advantages of the embodiment of the present application clearer, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0043] See also Figure 1 The present application example provides a coating system 100, including a frame 1, a coating device 2 and a cleaning device 3.

[0044] Please continue to read Figure 1 The coating device 2 is arranged on the frame 1 . The coating device 2 comprises a nozzle 21 and a roller 22 , and the nozzle 21 is arranged above the roller 22 .

[0045] Please combine Figures 1 to 3The cleaning device 3 includes a cleaning mechanism 31 and a moving mechanism 32. The cleaning mechanism 31 includes a cleaning block 311. Along the first direction D1, the cleaning block 311 has a cleaning side 3111 facing the roller 22 to be cleaned; an adsorption channel 312 is provided along the circumferential edge of the cleaning side 3111, and a flexible pad 314 is provided on the outer wall of the adsorption channel 312 for contacting with the roller surface of the roller 22; a dry ice nozzle 313 is provided in the middle of the cleaning side 3111. Along the first direction D1, the protruding height of the dry ice nozzle 313 does not exceed the protruding height of the adsorption channel 312, so that a gap is formed between the dry ice nozzle 313 and the roller surface when the adsorption channel 312 contacts with the roller surface. The moving mechanism 32 is arranged on the frame 1, and the cleaning block 311 is connected to the moving mechanism 32. The moving mechanism 32 is used to drive the cleaning block 311 to move along the axial direction of the roller 22.

[0046] When coating is performed using the coating system 100 provided in the example of the present application, the nozzle 21 sprays the slurry onto the diaphragm below, and the diaphragm passes through the gap between the roller 22 and the pressure roller and is transported to the rear end.

[0047] When the roller surface of the roller 22 is attached with slurry attachments, move the cleaning block 311 close to the roller 22 so that the adsorption channel 312 fits with the roller surface of the roller 22 through the flexible pad. Open the dry ice nozzle 313 to spray dry ice at the slurry attachments to knock them off. At the same time, open the adsorption channel 312 to adsorb the knocked-off slurry attachments. Open the moving mechanism 32 to drive the cleaning block 311 to move along the axial direction of the roller 22, and gradually clean different axial positions of the roller 22. In addition, since the roller 22 rotates during operation, the cleaning block 311 can be used to gradually clean different axial positions of the roller 22, thereby improving the cleaning efficiency.

[0048] Since the dry ice nozzle 313 does not directly contact the roller 22 , and the adsorption channel 312 contacts the roller 22 through the flexible pad 314 , the cleaning block 311 will not scratch the roller surface of the roller 22 during the movement of the cleaning block 311 .

[0049] The present application does not limit the specific shape of the cleaning block 311. In some possible embodiments, the cleaning side 3111 of the cleaning block 311 is a curved surface with four edges, two of which are arc-shaped and the other two are straight. The curvature of the arc-shaped edges is consistent with the curvature of the roller surface of the roller 22.

[0050] For further information, please refer to Figure 3 The cleaning block 311 is provided with an adsorption channel 312 along the circumferential edge of the cleaning side 3111. The adsorption channel 312 has an outer wall 3121 close to the edge and an inner wall 3122 close to the middle of the cleaning side 3111. The outer wall 3121 and the inner wall 3122 form the adsorption channel 312, and the adsorption channels 312 on all sides are connected to each other.

[0051] The dry ice nozzle 313 is disposed in the middle of the cleaning side 3111 .

[0052] Furthermore, a plurality of dry ice nozzles 313 may be arranged at intervals in the middle of the cleaning side 3111 .

[0053] Along the first direction D1 , the protruding height of the dry ice nozzle 313 does not exceed the protruding height of the adsorption channel 312 , so that a gap is formed between the dry ice nozzle 313 and the roller surface when the adsorption channel 312 is in contact with the roller surface.

[0054] When a plurality of dry ice nozzles 313 are arranged at intervals in the middle of the arc-shaped cleaning side 3111, the protruding height of the dry ice nozzle 313 does not exceed the protruding height of the adsorption channel 312, which means that along the axial direction D2 perpendicular to the first direction D1, the dry ice nozzle 313 and the adsorption channel 312 located on the same axial direction D2 connecting line, the protruding height of the dry ice nozzle 313 along the first direction D1 is less than the protruding height of the adsorption channel 312 along the first direction D1, so that when the adsorption channel 312 is in contact with the roller surface of the roller 22, there is a gap between the dry ice nozzle 313 located on the same axial direction D2 connecting line and the roller surface of the roller 22, and the dry ice nozzle 313 cannot directly contact the roller surface of the roller 22.

[0055] Since the adsorption channel 312 is arranged around the dry ice nozzle 313, the slurry attachments knocked off by the dry ice nozzle 313 will be blocked by the outer wall of the adsorption channel 312 and will not fall out of the cleaning side 3111. The slurry attachments knocked off by the dry ice nozzle 313 will be adsorbed into the adsorption channel 312 under the action of the adsorption force in the adsorption channel 312.

[0056] Further, in order to facilitate the absorption of the knocked-off slurry attachments into the absorption channel 312, in a possible embodiment, please continue to refer to Figure 3 and Figure 4 , along the first direction D1 , the protruding height of the inner wall 3122 is smaller than the protruding height of the outer wall 3121 .

[0057] Since the protruding height of the inner wall 3122 is smaller than the protruding height of the outer wall 3121 , when the outer wall 3121 fits the rolling surface of the roller 22 , the inner wall 3122 will not fit the rolling surface of the roller 22 , so that the slurry attachments knocked off by the dry ice nozzle 313 can be easily adsorbed into the adsorption channel 312 .

[0058] Furthermore, the flexible pad 314 may be disposed on the outer side wall 3121 .

[0059] Furthermore, the flexible pad 314 may be made of rubber or silicone material.

[0060] Furthermore, the material of the entire cleaning block 311 can be set to be a flexible material such as rubber or silicone.

[0061] Further, in order to facilitate the collection of the slurry attachment flowing out of the adsorption flow channel 312, in a possible embodiment, please combine Figure 2 and Figure 4 The cleaning mechanism 31 further includes an adsorbent storage box 315 , and the adsorbent storage box 315 is connected to the adsorption channel 312 through an adsorption tube 316 .

[0062] Furthermore, in order to facilitate the dry ice delivery of the dry ice nozzle 313, in a possible embodiment, the cleaning mechanism 31 further includes a dry ice storage box 317, and a dry ice compressor (not shown) is arranged in the dry ice storage box 317. The dry ice nozzle 313 is connected to the dry ice compressor through a dry ice delivery pipe 318.

[0063] The moving mechanism 32 is used to drive the cleaning block 311 to move along the axial direction D2, so as to use the cleaning block 311 to gradually clean different axial positions of the roller 22. The present application does not limit the specific type of the moving mechanism 32. In some possible embodiments, please continue to refer to Figure 2 The moving mechanism 32 includes a fixed rod 321 , a screw rod 322 , a fixed block 323 and a moving block 324 .

[0064] Both ends of the fixing rod 321 and the screw rod 322 are connected to the fixing block 323. The fixing block 323 can be arranged near the roller 22 of the frame 1, so that the extending direction of the fixing rod 321 and the screw rod 322 is consistent with the axial direction D2 of the roller 22.

[0065] The moving block 324 is threadedly connected to the screw rod 322 , and the moving block 324 is slidably connected to the fixed rod 321 . The moving block 324 can be moved along the axial direction D2 by rotating the screw rod 322 .

[0066] The cleaning block 311 is connected to the moving block 324 , and the moving block 324 can be used to drive the cleaning block 311 to move along the axial direction D2 of the roller 22 .

[0067] Furthermore, a motor may be used to drive the screw rod 322 to rotate.

[0068] The present application does not limit how the screw rod 322 and the fixed rod 321 are connected to the fixed block 323. In some possible embodiments, the two ends of the screw rod 322 are rotatably connected to the two fixed blocks 323, and one end of the screw rod 322 passes through the fixed block 323 and is connected to the motor. The two ends of the fixed rod 321 are fixedly connected to the two fixed blocks 323. The two fixed blocks 323 are respectively connected to the frame 1 connected to the two ends of the roller 22.

[0069] Furthermore, in some possible embodiments, the adsorbent storage box 315 and the dry ice storage box 317 may be connected to the fixing block 323 .

[0070] Further, in order to facilitate the connection between the dry ice delivery tube 318 and the adsorption tube 316, in a possible embodiment, please continue to refer to Figure 4 Two channels, namely, a first channel 3211 and a second channel 3212 extending along the axial direction D2, may be provided in the fixing rod 321. The dry ice delivery pipe 318 passes through the first channel 3211 and is connected to the dry ice nozzle 313 and the dry ice compressor, and the adsorption pipe 316 passes through the second channel 3212 and is connected to the adsorption flow channel 312 and the adsorbent storage box 315.

[0071] Since the moving block 324 drives the cleaning block 311 to move along the axial direction D2, the distance between the dry ice nozzle 313 and the dry ice storage box 317 will change. Further, in order to make the length of the dry ice delivery pipe 318 in the first channel 3211 adapt to the position requirement between the dry ice nozzle 313 and the dry ice storage box 317, in a possible embodiment, the dry ice delivery pipe 318 can be set as a retractable bellows.

[0072] For example, please refer to Figure 4 The side wall of the fixing rod 321 is provided with an opening 3213 communicating with the first channel 3211, and the opening 3213 extends along the axial direction D2. The bellows has a main pipe located in the first channel 3211, and a branch pipe extending from the opening 3213 of the side wall of the fixing rod 321 to the outside of the first channel 3211, and the branch pipe is connected to the dry ice nozzle 313 at the cleaning block 311.

[0073] When the moving block 324 drives the cleaning block 311 to move along the side close to the dry ice storage box 317 , the main pipe in the first channel 3211 contracts, and the branch pipe slides along the extending direction of the opening 3213 .

[0074] Likewise, when the moving block 324 drives the cleaning block 311 to move along a side away from the dry ice storage box 317 , the main pipe in the first channel 3211 is extended, and at the same time, the branch pipe slides along the extending direction of the opening 3213 .

[0075] Further, like the dry ice delivery tube 318 , the adsorption tube 316 may be configured as a shrinkable bellows.

[0076] In order to improve the service life of the cleaning block 311, in a possible embodiment, when there is no slurry attachment to be cleaned on the surface of the roller 22, the adsorption channel 312 of the cleaning block 311 can be separated from the roller surface of the roller 22, and the adsorption channel 312 can be fitted to the roller surface of the roller 22 when cleaning is needed.

[0077] Further, in order to facilitate the attachment or separation of the adsorption channel 312 and the roller 22, in some possible embodiments, please continue to refer to Figure 2 and Figure 3 The cleaning device 3 further includes a telescopic mechanism 33. The cleaning block 311 is connected to the moving block 324 via the telescopic mechanism 33, and the telescopic mechanism 33 is used to drive the cleaning block 311 to move along the first direction D1. The D1 direction refers to the direction close to the roller 22.

[0078] Further, the present application does not limit the specific structural type of the telescopic mechanism 33 , and in some possible embodiments, the telescopic mechanism 33 may include a cylinder, and the output end of the cylinder is connected to the cleaning block 311 , and the fixed end of the cylinder is connected to the moving block 324 .

[0079] Furthermore, in order to automatically drive the cylinder to move the cleaning block 311 along the first direction D1 when there is slurry attachment on the surface of the roller 22 so that the adsorption channel 312 fits with the roller surface of the roller 22, in some possible embodiments, the cleaning device 3 also includes a control mechanism 34.

[0080] The control mechanism 34 includes a camera 341 and a controller; the camera 341 is set on the fixed block 323, and the camera 341 and the cylinder are both connected to the controller signal. The camera 341 is used to send a signal to the controller when it is identified that there is slurry attachment on the roller 22. The controller receives the signal to control the cylinder to start, so as to drive the cleaning block 311 to move, so that the adsorption channel 312 fits the roller surface of the roller 22.

[0081] Furthermore, the controller may be used to control the start-up of the adsorption channel 312 and the dry ice nozzle 313 .

[0082] For example, the switch of the solenoid valve can be controlled by PLC. When the solenoid valve is opened, the cylinder performs telescopic movement; when the solenoid valve is closed, the cylinder stops moving.

[0083] For example, in some possible embodiments, see Figure 5 , the control process of PLC can include:

[0084] The detection module 342 is used to configure and link the nodes of the camera 341 to generate an initial self-organizing network, and integrate the initial shooting pictures and video encoding to generate a first self-organizing network;

[0085] A first transmission module 343 is used to transmit the captured image to the camera 341 for multi-path video stream propagation according to the generated first self-organizing network, so as to obtain an initial multi-path video stream;
