Description

Technical Field

[0001] This invention relates to the field of coating technology, and more particularly to a dry cleaning device and coating equipment. Background Technology

[0002] Electrodes are a crucial component in the manufacture of electrode assemblies, which are the parts within a single battery cell where electrochemical reactions occur. Electrode assemblies are primarily formed by winding or stacking positive and negative electrode sheets, typically with a separator between them. The portions of the positive and negative electrode sheets containing the active material constitute the main body of the electrode assembly. During the charging and discharging process of the battery, the anode and cathode active materials react with the electrolyte.

[0003] In the battery manufacturing process, the coating process of battery electrodes is a crucial step, typically performed using a coating machine. Currently, the most widely used battery coating technology for power batteries is slot die coating. As a precision wet coating technology, slot die coating works by extruding the coating slurry under pressure and flow rate along the lip of the coating die and transferring it onto the substrate.

[0004] After coating is completed, the wet coating slurry can easily remain on the lip of the coating die. Over time, the coating slurry can solidify on the surface of the lip, clogging the die outlet and affecting subsequent coating processes. To avoid this, existing technologies typically use manual cleaning to remove the coating slurry residue from the lip of the coating die. This cleaning method is not only time-consuming and labor-intensive, but it can also easily damage the lip of the coating die, resulting in low cleaning efficiency and increased production costs. Summary of the Invention

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0049] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0052] The main manufacturing processes for lithium-ion batteries include batching, coating, rolling, slitting, winding, assembly, formation, and capacity testing. Coating is one of the crucial steps in lithium-ion battery production. Coating refers to the process of applying positive or negative electrode coating slurry to the surface of a substrate to form positive or negative electrode sheets. After coating, the wet coating slurry can easily remain on the lip of the coating die. Over time, this slurry can solidify on the surface of the die lip, clogging the die outlet and affecting subsequent coating processes. This embodiment provides a dry cleaning device for coating dies to clean the lip after coating, removing residual slurry and solving the problems of low efficiency and easy damage to the lip caused by manual cleaning in existing technologies.

[0053] like Figures 1-5 As shown, this embodiment provides a dry cleaning device for cleaning a coating die assembly 200. The dry cleaning device includes a vertical plate 100, a material storage assembly 300, and a gripper moving module 600. The coating die assembly 200 is mounted on the vertical plate 100. The material storage assembly 300 is also mounted on the vertical plate 100 and located on at least one side of the coating die assembly 200. The material storage assembly 300 stores a sponge block 400 that can cover the lip of the coating die assembly 200. The gripper moving module 600 is mounted on the vertical plate 100 and configured to grasp the sponge block 400 and move it along the lip of the coating die assembly 200.

[0054] After the coating die assembly 200 completes the coating process, the coating die assembly 200 retracts, driving the gripper moving module 600 to grasp the sponge block 400 and move it along the lip of the coating die assembly, so that the sponge block 400 wipes the lip. This achieves automation and effectively improves cleaning efficiency compared with existing manual cleaning. By using the sponge block 400 to wipe the lip, damage to the lip by the sponge block 400 itself is avoided, and the cleaning effect is good.

[0055] Optionally, the gripper moving module 600 includes a gripper assembly 620, a first moving assembly 610, and a second moving assembly 630. The gripper assembly 620 is mounted on the first moving assembly 610. The first moving assembly 610 drives the gripper assembly 620 to move in the X direction, and the second moving assembly 630 drives the first moving assembly 610 to move in the Z direction. When wiping the lips, the second moving assembly 630 drives the first moving assembly 610 to move in the Z direction, and the first moving assembly 610 drives the gripper assembly 620 to move until it is flush with the sponge block 400. After the gripper assembly 620 grips the sponge block 400, the first moving assembly 610 drives the gripper assembly 620 to move in the X direction, so that the sponge block 400 wipes the lips, thus achieving automation and improving cleaning efficiency.

[0056] Specifically, see Figures 6-8The first moving component 610 includes a moving block 611, a slide rod 612, and a second driving member. The slide rod 612 is connected to the output end of the second moving component 630. The moving block 611 is slidably sleeved on the slide rod 612. The second driving member drives the moving block 611 to slide along the slide rod 612. When the coating die assembly 200 approaches the steel roller assembly 500 for coating, the second moving component 630 drives the slide rod 612 to raise the moving block 611 along the Z direction to a position that will not interfere with the coating die assembly 200. When the coating die assembly 200 retracts away from the steel roller assembly 500, the second moving component 630 drives the slide rod 612 to lower the moving block 611 along the Z direction to a position close to the storage assembly 300. The moving block 611 is slidably sleeved on the slide rod 612, and the second driving member drives the moving block 611 to slide along the slide rod 612 to achieve movement of the moving block 611 along the X direction.

[0057] The gripper moving module 600 also includes a gripper assembly 620, which includes a gripper 621, a gripper cylinder 622, and a third driving member. The gripper cylinder 622 is slidably mounted on the bottom of the moving block 611, and the gripper 621 is located at the output end of the gripper cylinder 622. The gripper cylinder 622 can control the opening and closing of the gripper 621. The third driving member is located at the bottom of the moving block 611 and is used to drive the gripper assembly 620 to slide along the first moving assembly 610. Figure 7 and Figure 8 As shown, the second moving component 630 drives the gripper moving module 600 to move along the Z direction, making the gripper assembly 620 flush with the storage assembly 300. The third driving component drives the gripper cylinder 622 to slide along the first moving component 610, causing the gripper 621 to abut against the sponge block 400. The gripper cylinder 622 controls the gripper 621 to open, allowing the gripper 621 to grasp the sponge block 400, completing the gripping action. Optionally, the bottom of the moving block 611 is specifically provided with a slider 6111, and the gripper cylinder 622 is slidably connected to the slider 6111 of the moving block 611 to improve the stability of the sliding process. The second moving component 630, the second driving component, and the third driving component can all be cylinders or motors, which can be set as needed.

[0058] In this embodiment, the dry cleaning device for coating die head also includes a sensing component. The gripper cylinder 622 and the third drive component are both communicatively connected to the sensing component. The sensing component is used to control the opening and closing of the gripper cylinder 622 and the third drive component. When the gripper component 620 moves to the corresponding position, the sensing component instructs the gripper cylinder 622 and the third drive component to perform corresponding actions, effectively improving the efficiency of the operation.

[0059] Optionally, see Figure 1The upright plate 100 is provided with two parallel support rods 800. Two second moving components 630 are respectively mounted on the two support rods 800. The dry cleaning device for the coating die head also includes a connecting plate 900. One end of the connecting plate 900 is connected to the output end of one of the second moving components 630, and the other end of the connecting plate 900 is connected to the output end of the other second moving component 630. Both ends of the slide rod 612 are respectively fixed to the connecting plate 900. The two second moving components 630 simultaneously drive the connecting plate 900 to move in the Z direction. The connecting plate 900 drives the slide rod 612 and the first moving component 610 to move in the Z direction, thereby improving the stability of the movement.

[0060] In this embodiment, the upright plate 100 is preferably provided with two material storage components 300. The two material storage components 300 are respectively located on both sides of the coating die head assembly 200. When the gripper assembly 620 grabs the sponge block 400 from the material storage component 300 on one side and moves it along one side of the lip to wipe the other side, the gripper assembly 620 can replace the sponge block 400 from the material storage component 300 on the other side to ensure that the sponge block 400 is clean before wiping, so as to improve the wiping effect.

[0061] Optionally, the sensing component includes a sensing element 710 and a sensing switch 720. The sensing switch 720 is mounted on the connecting plate 900, and the sensing element 710 is mounted on the moving block 611. When the moving block 611 moves, it drives the sensing element 710 to move. When the sensing switch 720 senses the sensing element 710, the sensing switch 720 instructs the gripper cylinder 622 and the third drive component to perform corresponding actions, which effectively improves the efficiency of the operation.

[0062] Preferably, see continue to see Figure 1In this embodiment, inductive switches 720 are provided at points B, C, D, and E. When the sensing plate 710 moves to point B, the inductive switch 720 at point B turns on, the gripper cylinder 622 extends and controls the gripper 621 to open to grab the sponge block 400 stored in the material storage component 300 located on one side of the coating die assembly 200. Subsequently, the inductive switch 720 turns off, and the gripper cylinder 622 retracts. When the sensing plate 710 moves to point C, the inductive switch 720 at point C turns on, the gripper cylinder 622 extends and presses the sponge block 400 against the die lip, and the wiping operation begins. When the sensing plate 710 moves to point D, the inductive switch 720 at point D turns on. When switch 720 is turned on, gripper cylinder 622 retracts, causing sponge block 400 to detach from the die head lip, ending the wiping operation. Gripper cylinder 622 then controls gripper 621 to open and remove sponge block 400. When sensor plate 710 moves to point E, sensor switch 720 at point E is turned on, gripper cylinder 622 extends, and gripper 621 is already open. Gripper 621 grabs sponge block 400 stored in storage assembly 300 on the other side of coating die head assembly 200. Then sensor switch 720 is turned off, gripper cylinder 622 retracts, and the machine awaits the start of the next cleaning operation. When the wiping operation begins again, the sensor switch 720 at point E is activated, the gripper 621 has grasped the clean sponge block 400, and the gripper cylinder 622 is in the retracted state. When the sensor plate 710 moves to point D, the sensor switch 720 at point D is activated, the gripper cylinder 622 extends and presses the sponge block 400 against the die lip, and the wiping operation begins. When the sensor plate 710 moves to point C, the sensor switch 720 at point C is activated, the gripper cylinder 622 retracts and the sponge block 400 is removed from the die lip, the wiping operation ends, and the gripper cylinder 622 controls the gripper 621 to open to remove the sponge block 400. When the sensor plate 710 moves to point B, the sensor switch 720 at point B is activated, the gripper cylinder 622 is in the retracted state, and the gripper 621 is in the open state. The second moving component 630 drives the gripper moving module 600 to rise back to the default initial state.

[0063] Optionally, a cable chain fixing plate 1100 is provided on the connecting plate 900. The cable chain fixing plate 1100 is connected to the connecting plate 900 through the mounting plate 1000. The mounting plate 1000 and the top surface of the moving block 611 are slidably connected. The cable chain fixing plate 1100 is used to install the cable chain, and the cable chain is used to protect the wires and cables.

[0064] like Figures 9-11As shown, optionally, the storage assembly 300 includes a support 310, a storage bin 320, and a pusher 330. The support 310 is mounted on the upright plate 100; the storage bin 320 is disposed on the support 310 and stores a sponge block 400; the pusher 330 is disposed on the support 310 and can push the sponge block 400 to the opening of the storage bin 320. After the gripper assembly 620 is flush with the storage assembly 300, the pusher 330 pushes the sponge block 400 to the opening of the storage bin 320, so that the gripper assembly 620 can grasp the sponge block 400. In this embodiment, the pusher 330 is set as an electric cylinder, which operates smoothly and positions accurately. In other embodiments, the pusher 330 can also be set as other driving components such as a motor that can push the sponge block 400 to move, as needed.

[0065] Optionally, the support 310 includes a first support plate 311, a second support plate 312, and an extension plate 313 for connecting the first support plate 311 and the second support plate 312. The second support plate 312 is mounted on the upright plate 100, and the storage bin 320 and the ejector 330 are both mounted on the side of the first support plate 311 away from the second support plate 312. The extension plate 313 can effectively increase the height of the support 310, thereby increasing the height of the storage bin 320, making it flush with the gripper assembly 620 and the lip. A reinforcing rib 314 is provided between the first support plate 311 and the extension plate 313 to improve the support strength of the support 310.

[0066] Preferably, multiple sponge blocks 400 are provided, arranged side by side, and the maximum pushing stroke of the pusher 330 is equal to the sum of the thicknesses of the multiple sponge blocks 400. The pusher 330 pushes the outermost sponge block 400 to the hopper opening each time. When the maximum pushing stroke of the pusher 330 is completed, it indicates that the sponge block 400 has been used up. Multiple sponge blocks 400 can increase the frequency of cleaning processes, eliminating the need to frequently add new sponge blocks 400 to the storage hopper 320. During use, the thickness and quantity of the sponge blocks 400 can be set according to actual needs. In this embodiment, the storage assembly 300 also includes an alarm. When the maximum pushing stroke of the pusher 330 is completed and the sponge block 400 is used up, the alarm can emit an alarm signal to prompt manual replenishment.

[0067] The present invention also provides a coating device, including a coating die assembly 200 and the aforementioned dry cleaning device, which can realize automated cleaning of the lip of the coating die assembly 200, effectively improving cleaning efficiency and reducing labor costs.

[0068] The coating die assembly 200 in this embodiment includes an extrusion die 210, a first base plate 220, and a second base plate 230. The second base plate 230 is slidably connected to the guide rail 110 of the vertical plate 100. The extrusion die 210 is mounted on the second base plate 230 via the first base plate 220. The first base plate 220 can effectively increase the height of the extrusion die 210 to match the height of the steel roller assembly 500. Optionally, the vertical plate 100 is also provided with a crossbeam 120 for supporting the steel roller assembly 500.

[0069] In application, for example, a steel roller assembly 500 is provided on the upright plate 100, and a coating die assembly 200 is slidably disposed on the upright plate 100. The coating die assembly 200 can approach or move away from the steel roller assembly 500. The coating die assembly 200 approaches the steel roller assembly 500 to coat it. After coating is completed, the coating die assembly 200 retracts to the initial position. Subsequently, the gripper moving module 600 grasps the sponge block 400 and moves it along the lip of the coating die assembly 200, so that the sponge block 400 wipes the lip, thereby realizing automated cleaning and improving cleaning efficiency.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
