Description

Technical Field

[0001] This utility model relates to the field of lithium battery coating technology, and in particular to an ultrasonic material box. Background Technology

[0002] In the manufacturing process of lithium battery electrodes, the coating process requires uniformly applying slurry to the surface of the substrate. In actual operation, due to the high-speed rotation of the coating rollers and the rheological properties of the slurry, slurry splashing often occurs—excess slurry splatters onto the inner wall of the coating machine's hopper, the baffles, and the surface of the flip-top components. If this slurry residue is not cleaned promptly, it will not only dry and form particles that contaminate subsequent products, but it will also cause the baffle seals to fail, severely affecting coating uniformity and yield.

[0003] Currently, the industry generally uses manual cleaning: after each coating cycle, the machine must be stopped and components such as the material box and baffles disassembled. Operators then physically scrape off and solvent-clean the residual slurry, and finally reassemble and test the equipment. Manual cleaning is time-consuming for each disassembly and cleaning, significantly reducing effective production time; it also requires dedicated personnel, resulting in manpower redundancy in continuous production scenarios; furthermore, frequent disassembly and assembly accelerates component wear and increases equipment maintenance costs.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0040] Reference Figures 1 to 4This invention provides an ultrasonic material box for use in lithium battery coating. It can self-clean the material box 1, effectively improving production efficiency. The ultrasonic material box includes a material box 1 and a lifting assembly 3. The material box 1 is positioned below a gravure roller 5 to supply slurry to the gravure roller 5. A scraper 6 is provided above the gravure roller 5 to remove excess slurry from its surface. The lifting assembly 3 drives the material box 1 to move vertically closer to or further away from the gravure roller 5. Baffles 4 are erected around the material box 1 and can be flipped inwards. A flip-top assembly 2 is provided on the material box 1 to drive the baffles 4 to flip. An ultrasonic generator 7 is installed outside the material box 1, and an ultrasonic transducer 71 is installed on the material box 1. The ultrasonic transducer 71 is electrically connected to the ultrasonic generator 7. The bottom of the material box 1 is provided with a feed inlet 111 and a waste outlet 112. The feed inlet 111 is connected to the feed pipe 17, and the slurry can be transferred into the material box 1 from the feed inlet 111. The waste outlet 112 is connected to the waste pipe 16, and the waste slurry can be discharged from the material box 1 from the waste outlet 112.

[0041] This invention relates to an ultrasonic cleaning box that uses an ultrasonic transducer 71 and an ultrasonic generator 7 to clean the box 1. The ultrasonic transducer 71 and the ultrasonic generator 7 work together; the ultrasonic generator 7 converts ordinary electrical energy into high-frequency electrical energy, which is then transmitted to the ultrasonic transducer 71. The ultrasonic transducer 71 converts the received high-frequency electrical energy into mechanical vibrations of the same frequency, which act on the box 1. This, combined with the cleaning fluid inside the box 1, effectively cleans the box 1. Furthermore, the baffle 4 is designed to be flipped; during cleaning, the baffle 4 can simply be flipped inside the box 1 for cleaning, effectively reducing labor costs and improving cleaning efficiency.

[0042] Reference Figure 1 and Figure 4 Furthermore, the ultrasonic transducer 71 is an ultrasonic vibrator, and an array of ultrasonic vibrators is arranged at the bottom of the outer side of the material box 1.

[0043] In other embodiments, the ultrasonic transducer 71 may be configured as an ultrasonic vibrating plate, which is attached to the bottom of the outer side of the material box 1.

[0044] Alternatively, the ultrasonic transducer 71 may be configured as an ultrasonic vibrating rod. In this embodiment, an array of ultrasonic vibrating rods is arranged at the bottom of the outer side of the material box 1.

[0045] Furthermore, the bottom of the material box 1 is covered with a sound-absorbing bottom cover 8, which is detachably connected and fixed, and the ultrasonic transducer 71 is disposed inside the sound-absorbing bottom cover 8. Since the ultrasonic transducer 71 generates a large amount of noise when performing ultrasonic vibration, the sound-absorbing bottom cover 8 can effectively reduce the noise level and help ensure the comfort of the working environment.

[0046] Reference Figure 1 In this embodiment, a buckle 81 is provided on the sound-absorbing bottom cover 8, and a corresponding fastening part is provided on the material box 1. The buckle 81 and the fastening part cooperate to realize the detachable fixing of the sound-absorbing bottom cover 8 and the material box 1.

[0047] The baffles 4 can be flipped and are set around the material box 1. Specifically, each of the baffles 4 has a hinge 41 at the end near the material box 1. Each baffle 4 is hinged to the material box 1 through the corresponding hinge 41. The baffles 4 are set around the top of the material box 1 to block and intercept the slurry that splashes to the sides during the coating process, so as to reduce the pollution of the working environment and the waste of slurry caused by the slurry splashing everywhere.

[0048] Reference Figure 2 The flip-top assembly 2 drives the surrounding baffles 4 to flip into the material box 1. Specifically, the flip-top assembly 2 is configured to correspond one-to-one with the surrounding baffles 4. The flip-top assembly 2 includes a flip-top cylinder 21 and a flip-top pusher 23. The flip-top cylinder 21 is installed on the outside of the material box 1, and the piston rod of the flip-top cylinder 21 is fixedly connected to a fisheye connector 22. One end of the flip-top pusher 23 is fixedly connected to the baffle 4, and the other end is rotatably connected to the fisheye connector 22. The extension / retraction of the flip-top cylinder 21 drives the flip-top pusher 23 to move, thereby pushing the surrounding baffles 4 to flip.

[0049] In this embodiment, the flip-top assembly 2 is installed on both ends of the material box 1. Correspondingly, the flip-top push block 23 connected to the baffles 4 at both ends of the material box 1 is set as an L-shaped push block. The piston rod of the flip-top cylinder 21 connected to the L-shaped push block extends and drives the fish-eye connector 22 connected to it to rise, so that the height of the end of the L-shaped push block connected to the fish-eye connector 22 changes accordingly, pushing the flip-top push block 23 to rotate, thereby pushing the baffle 4 to flip towards the inside of the material box 1. Conversely, when the piston rod of the flip-top cylinder 21 retracts, it drives the L-shaped push block to pull the baffle 4 to stand upright, so as to surround both ends of the material box 1.

[0050] The flip-top pusher 23, which is connected to the baffles 4 on both sides of the material box 1, is configured as a chamfered pusher. The length of the chamfered pusher connected to the fisheye connector 22 is greater than the length of the side connected to the baffle 4. In use, the piston rod of the flip-top cylinder 21 connected to the chamfered pusher extends, causing the height of the fisheye connector 22 connected to it to rise. This causes the height of the end of the chamfered pusher connected to the fisheye connector 22 to rise accordingly, which in turn causes the chamfered pusher to flip to both sides, thereby pulling the baffles 4 upright. At this time, the baffles 4 on both sides surround the opposite sides of the material box 1. Conversely, when the piston rod of the flip-top cylinder 21 retracts, it causes the chamfered pusher to flip to the center, thereby pushing the baffles 4 to flip and enter the material box 1.

[0051] In use, by controlling the output states of the flip-top cylinder 21 connected to the two end baffles 4 and the flip-top cylinder 21 connected to the opposite two side baffles 4 respectively, the baffles 4 on all four sides can be simultaneously erected or flipped into the material box 1.

[0052] In this embodiment, the flip-top pusher 23 can push the baffle 4 to rotate 90°, so that the baffle 4 is in a vertical enclosure state or a horizontal waiting-to-clean state. When the baffle 4 is in a horizontal state, the plane of the baffle 4 is lower than the height of the opening of the material box 1.

[0053] Reference Figure 2 and Figure 4 The lifting assembly 3 is used to drive the material box 1 to move vertically. Specifically, the lifting assembly 3 includes a drive motor 33, a rotating shaft 32, a drive gear 321, a lifting rod 31, and a fixing block 34. The drive motor 33 is fixedly installed and connected to the rotating shaft 32 to drive the rotating shaft 32 to rotate. The fixing block 34 is fixedly installed and located below the material box 1. One end of the lifting rod 31 is fixedly connected to the bottom of the material box 1, and the end of the lifting rod 31 away from the material box 1 is slidably installed on the fixing block 34. 4. The lifting rod 31 has evenly spaced toothed grooves along its length. The rotating shaft 32 is rotatably mounted below the material box 1. In actual installation, both ends of the rotating shaft 32 can be fixed by bearings with seats, etc. The drive gear 321 is fixedly sleeved on the rotating shaft 32, and the drive gear 321 meshes with the toothed grooves. The drive motor 33 drives the rotating shaft 32 to rotate, thereby driving the drive gear 321 to rotate synchronously. The rotation of the drive gear 321 causes the lifting rod 31 to slide vertically against the fixed block 34, thereby realizing the lifting and lowering of the material box 1. In this embodiment, both ends of the rotating shaft 32 are fixedly sleeved with drive gears 321. The number and position of the lifting rods 31 correspond to the drive gears 321, and the number and position of the fixed blocks 34 correspond to the lifting rods 31.

[0054] Reference Figure 2 and Figure 3 Furthermore, a limiting groove 311 is formed on the side of the lifting rod 31 facing away from the tooth groove. The length direction of the limiting groove 311 is consistent with the length direction of the lifting rod 31. A limiting block 341 is fixedly installed on the fixing block 34, and the limiting block 341 slides in the limiting groove 311. During the lifting rod 31's lifting and lowering movement, the limiting block 341 slides in the limiting groove 311. When the limiting block 341 abuts against the groove walls at both ends of the limiting groove 311, the lifting rod 31 stops rising / falling, thereby limiting the travel of the lifting rod 31.

[0055] Reference Figure 2Furthermore, the inner bottom surface of the material box 1 includes a central bottom surface 11 and guide ramps 12 disposed on both sides of the central bottom surface 11. The guide ramps 12 on both sides are inclined upward relative to the central bottom surface 11. The inlet 111 and the waste outlet 112 are both located on the central bottom surface 11. By setting the inner bottom surface of the material box 1 to be inclined from both sides to the middle, i.e., high on both sides and low in the middle, when it is necessary to recycle the material in the material box 1, the guide ramps 12 on both sides guide the material in the material box 1 to ensure that the material in the material box 1 can completely flow out of the material box 1.

[0056] Reference Figure 1 and Figure 4 Furthermore, a return port 121 located on the guide slope 12 is provided on the bottom surface of the material box 1, and the return port 121 is connected to a return pipe. An overflow plate 13 is vertically installed on the side of the return port 121 near the middle bottom surface 11. The overflow plate 13 divides the interior of the material box 1 into a coating chamber and an overflow chamber, with the return port 121 located in the overflow chamber and the inlet 111 and waste outlet 112 located in the coating chamber. The height of the overflow plate 13 can be set according to actual production needs. When there is a lot of slurry in the coating chamber, the slurry will overflow the overflow plate 13 and enter the overflow chamber, flowing out of the material box 1 from the return port 121 and being recycled. The cooperation between the return port 121 and the overflow plate 13 can precisely control the amount of slurry in the material box 1, which is beneficial to achieving uniform coating.

[0057] Reference Figure 1 and Figure 2Furthermore, in this embodiment, the return port 121 includes a first return port 1211 and a second return port 1212. The first return port 1211 is connected to a first return pipe 14. A cleaning three-way valve 141 is connected in the transmission path of the first return pipe 14. The other two valve ports of the cleaning three-way valve 141 are respectively connected to a return branch pipe (not shown in the figure) and a cleaning inlet pipe (not shown in the figure). The cleaning fluid can be transported from the cleaning inlet pipe to the material box 1. The slurry in the overflow chamber can be discharged from the return branch pipe. The waste port 112 is connected to a waste pipe 16. A waste three-way valve 161 is provided in the transmission path of the waste pipe 16. The other two valve ports of the waste three-way valve 161 are respectively connected to a waste branch pipe (not shown in the figure) and a first cleaning branch pipe 162. The waste discharged from the waste port 112 can be discharged and recycled from the waste branch pipe, and the cleaning fluid discharged from the waste port 112 can be discharged from the first cleaning branch pipe 162. The feed inlet 111 is connected to the feed pipe 17. A feed three-way valve 171 is installed in the transmission path of the feed pipe 17. The other two valve ports of the feed three-way valve 171 are connected to the second cleaning branch pipe 172 and the feed branch pipe (not shown in the figure), respectively. The coating slurry can be conveyed into the material box 1 through the feed branch pipe, and the cleaning liquid discharged from the feed inlet 111 can be discharged through the second cleaning branch pipe 172. The second return port 1212 is connected to the second return pipe 15. The second return pipe 15, the first cleaning branch pipe 162, and the second cleaning branch pipe 172 converge and connect to the cleaning liquid outlet pipe (not shown in the figure). A two-way valve 18 is connected in the transmission path of the cleaning liquid outlet pipe.

[0058] Control the feed three-way valve 171 so that when the feed inlet 111-feed pipe 17-feed branch pipe are connected, the slurry can be conveyed into the material box 1 through the feed inlet 111; when the feed inlet 111-feed pipe 17-second cleaning branch pipe 172 are connected, further control the two-way valve 18 so that when the feed inlet 111-feed pipe 17-second cleaning branch pipe 172-cleaning liquid outlet pipe are connected, the cleaning liquid in the coating chamber can be discharged through the feed inlet 111.

[0059] The three-way valve 141 controls the cleaning process. When the first return port 1211-first return pipe 14-return branch pipe are connected, the slurry that has not passed the overflow plate 13 can be recovered. When the first return port 1211-first return pipe 14-cleaning inlet pipe are connected, the cleaning fluid can be delivered to the overflow chamber.

[0060] The waste three-way valve 161 is controlled so that when the waste port 112 and the waste branch pipe are connected, the waste discharged from the waste port 112 can be discharged and recycled through the waste branch pipe; when the waste port 112 and the first cleaning branch pipe 162 are connected, the two-way valve 18 is further controlled so that when the waste port 112, the first cleaning branch pipe 162 and the cleaning liquid outlet pipe are connected, the cleaning liquid discharged from the waste port 112 can be discharged and recycled through the cleaning liquid outlet pipe.

[0061] Control the two-way valve 18. When the second return port 1212-second return pipe 15-cleaning liquid outlet pipe are connected, the cleaning liquid discharged from the second return port 1212 can be discharged and recycled from the cleaning liquid outlet pipe.

[0062] The working process of this utility model is as follows:

[0063] When the material box 1 is working, the slurry is conveyed into the material box 1 from the feed port 111. The gravure roller 5 rotates clockwise to carry the slurry. During the rotation of the gravure roller 5, the scraper 6 scrapes off the excess slurry. Excess slurry in the material box 1 will overflow the overflow plate 13 and be recycled from the first return port 1211. When the gravure roller 5 rotates at a high speed, the slurry will be thrown onto the side wall of the material box 1 and the baffles 4 around it.

[0064] At the end of the coating process, the feed inlet 111 is closed and the waste outlet 112 is opened. Waste is discharged and recycled from the waste branch pipe. After the slurry discharge is completed, the waste outlet 112 is closed. Dry and wet slurry residues remain on the inner wall of the material box 1 and on the baffles 4 around it, requiring cleaning.

[0065] During cleaning, the lifting assembly 3 is first driven to move the material box 1 away from the gravure roller 5. Then, the cleaning three-way valve 141 is controlled so that the cleaning fluid output from the cleaning inlet pipe enters the overflow chamber from the first return port 1211. When the cleaning fluid passes the overflow plate 13, it enters the coating chamber and then fills the entire material box 1. During this process, the flip-top cylinder 21 in the flip-top assembly 2 is driven to work, so that the baffles 4 around the box 1 are rotated 90° into the material box 1. When the cleaning fluid passes the baffles 4, the ultrasonic generator 7 is started. The ultrasonic transducer transmits ultrasonic vibration to the material box 1 so that the cleaning fluid cleans the side wall of the material box 1 and the baffles 4. Upon completion of cleaning, turn off the ultrasonic generator 7, and connect the second return port 1212-second return pipe 15-cleaning fluid outlet, the waste port 112-first cleaning branch pipe 162-cleaning fluid outlet, and the inlet 111-inlet pipe 17-second cleaning branch pipe 172-cleaning fluid outlet to drain all the cleaning wastewater from the material box 1. Finally, activate the flip-top assembly 2 to return the baffle 4 to its upright position; and activate the lifting assembly 3 to raise the material box 1 back to its original position, completing one cycle. This process is repeated continuously.
