Abstract
Description
Technical Field
[0001] This application relates to the field of electrode production technology, and in particular to a slurry scraping device and coating machine for the empty foil area of an electrode. Background Technology
[0002] In the electrode manufacturing process, the positive and negative electrode active slurries are first uniformly coated onto the current collector using a coating machine, and then the organic solvents are removed by a drying system.
[0003] In actual production, electrodes have different design requirements, some of which require the formation of empty foil areas on the electrode. The existing method for forming these empty foil areas involves drying the slurry on the electrode to form a coating, then using a scraper to remove the coating from the empty foil areas. Correspondingly, after scraping, the scraper needs to be kept away from the electrode. Therefore, existing slurry scraping devices require multiple drive units.
[0004] Specifically, existing slurry coating devices often include a horizontal drive unit and a lifting drive unit. The horizontal movement of the scraper is achieved through the translation drive unit, and the lifting drive unit is used to raise and lower the scraper.

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0057] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0058] Please see Figures 1 to 3 The first aspect of this application provides a slurry scraping device for the empty foil area of an electrode sheet, including: a fixed frame 10, a driving component 20, a lifting frame 30, a translation frame 40, a scraping head 50, a rotating lifting structure and a rotating translation structure.
[0059] The drive element 20 is mounted on the fixed frame 10 and has a rotatable rotating end 21. In application, the drive element 20 can be, for example, a rotary motor. The rotating end 21 is a rotatable shaft that can be driven to rotate when the drive element 20 is started.
[0060] The lifting frame 30 is slidably mounted on the fixed frame 10 in the vertical direction; the translation frame 40 is slidably mounted on the lifting frame 30 in the horizontal direction; and the scraping head 50 is mounted on the translation frame 40. Specifically, in this embodiment, the device is described as being placed horizontally, where the vertical direction is... Figure 1 The Y-axis direction in the middle, the horizontal direction is Figure 1 The X-axis direction in the diagram.
[0061] The rotating lifting structure connects the lifting frame 30 and the rotating end 21, and is used to drive the lifting frame 30 to move vertically when the rotating end 21 rotates; the rotating translation structure connects the translation frame 40 and the rotating end 21, and is used to drive the translation frame 40 to move horizontally when the rotating end 21 rotates.
[0062] The specific structures of the rotary lifting structure and the rotary translation structure are as follows: Figure 1 and Figure 2 Not shown in the image.
[0063] In this embodiment, the rotary lifting structure and the rotary translation structure can adopt existing mechanisms that convert rotation into translation, such as crank-slider mechanisms. When using existing mechanisms, the connection relationship can be configured by a technician according to the actual situation, specifically ensuring that the rotating end 21 can drive the lifting frame 30 to rise and fall and drive the translation frame 40 to translate horizontally when it rotates.
[0064] In one embodiment, the rotary lifting structure includes a lead screw; the rotary translation structure may include a worm gear. Specifically, the rotating end 21 has a section configured as a lead screw and a section configured as a worm gear. When the rotating end 21 rotates, both the lead screw and the worm gear rotate horizontally. The lifting frame 30 meshes with the lead screw, so that when the lead screw rotates, the lifting frame 30 can move vertically under the guidance of the fixed frame 10. The worm gear is rotatably mounted on the translation frame 40 and meshes with the worm gear, so that when the worm gear rotates, the worm gear can drive the translation frame 40 to move horizontally. During startup, the drive member 20 can control the lead screw and the worm gear to rotate in different directions by rotating forward and backward, thereby controlling the lifting frame 30 and the translation frame 40 to move in different directions. It should be noted that in this embodiment, the lead screw and worm gear structure can both adopt the structure in the prior art. Therefore, although the specific structural diagram is not shown in this embodiment, the technicians can install and adapt it according to the prior art, so that when the rotating end 21 rotates, it can drive the lifting frame 30 to rise and fall and drive the translation frame 40 to translate.
[0065] In this embodiment, since the translation frame 40 is mounted on the lifting frame 30, the translation frame 40 and the scraping head 50 can be simultaneously driven to rise and fall when the lifting frame 30 rises and falls. The scraping head 50 can be simultaneously driven to move when the translation frame 40 moves. Therefore, with the cooperation of the above components, only the driving component 20 is needed to drive the scraping head 50 to rise, fall, and move, thereby enabling the scraping head 50 to scrape away the coating in the empty foil area.
[0066] Compared to setting separate lifting and horizontal drive units, this solution effectively reduces the number of drive mechanisms and lowers equipment costs. Furthermore, since the translation and lifting movements of the scraping head 50 are controlled by the same drive unit 20, the automatic control system connected to this device does not need to address the interaction issues caused by multiple drive units. This also reduces the complexity of the control logic for the drive unit 20 and avoids the time delays in controlling the movement of the lifting frame 30 and the translation frame 40 caused by multiple drive units.
[0067] In a more specific embodiment, the rotary lifting structure includes a first annular curved track 22 and a first slider 31; the first annular curved track 22 is arranged around the rotating end 21; the first slider 31 is disposed on the lifting frame 30 and can slide into the first annular curved track 22; during the rotation of the rotating end 21, the first annular curved track 22 pushes the first slider 31 to rise and fall.
[0068] Specifically, the first annular curved track 22 has an inner surface that undulates along the axial direction of the rotating end 21. During the sliding of the first slider 31 relative to the first annular curved track 22, the undulating inner surface of the first annular curved track 22 can push the first slider 31 to rise and fall, thereby driving the lifting frame 30 to rise and fall through the first slider 31.
[0069] Furthermore, the rotational translation structure includes a second annular curved track 23, a second slider 41, and a rotating member 42; the second annular curved track 23 is arranged around the rotating end 21; the middle part of the rotating member 42 is rotatably connected to the fixed frame 10, one end of the rotating member 42 is rotatably and slidably connected to the second slider 41, and the other end of the rotating member 42 is rotatably and slidably connected to the translation frame 40; the second slider 41 can slidably extend into the second annular curved track 23; during the rotation of the rotating end 21, the second annular curved track 23 pushes the second slider 41 up and down, so as to drive the rotating member 42 to rotate around its middle part and drive the translation frame 40 to translate.
[0070] Similarly, the second annular curved track 23 has an inner surface that undulates along the axial direction of the rotating end 21. During the sliding process of the second slider 41 relative to the second annular curved track 23, the undulating inner surface of the second annular curved track 23 can push the second slider 41 up and down, thereby driving the rotating member 42 to rotate around its middle part through the second slider 41. The rotating member 42 can be L-shaped.
[0071] During the rotation of the rotating component 41, the movement trajectories of one end and the other end of the rotating component 42 are not straight lines, because both ends need to rotate around their midpoints. Therefore, the actual movement trajectories of one end and the other end of the rotating component 41 are arc-shaped. Consequently, during the lifting and lowering of the second slider 41, one end of the rotating component 42, in addition to following the lifting and lowering of the second slider 41, will also experience a horizontal positional offset relative to the second slider 41. Similarly, during the horizontal translation of the translation frame 40 driven by the other end of the rotating component 42, the other end of the rotating component 42 will also experience a vertical positional offset relative to the translation frame 40. Therefore, in this embodiment, one end of the rotating component 42 is rotatably and slidably connected to the second slider 41, and the other end of the rotating component 42 is rotatably and slidably connected to the translation frame 40, so that the second slider 41 can smoothly drive the rotating component 42 to rotate and the rotating component 42 can smoothly drive the translation frame 40 to translate.
[0072] As one implementation method, please refer to Figures 1 to 6 The other end of the rotating member 42 may be provided with a buffer block 421. The other end of the rotating member 42 is rotatably connected to the buffer block 421, and the buffer block 421 is slidably connected to the translation frame 40 in the vertical direction, so that the rotating member 42 can rotate and be slidably connected to the translation frame 40. During the rotation of the other end of the rotating member 42, it can drive the buffer block 421 and the translation frame 40 to move in the horizontal direction, and at the same time, the buffer block 421 realizes its relative displacement with respect to the translation frame 40 in the vertical direction.
[0073] In one embodiment, one end of the rotating member 42 can be connected to the second slider 41 in a manner similar to that of the buffer block 421, so as to achieve a rotatable and slidable connection between the rotating member 42 and the second slider 41.
[0074] In one embodiment provided in this application, the rotation and translation structure further includes a first follower frame 43; the first follower frame 43 is slidably disposed on the fixed frame 10 in the vertical direction; and a second slider 41 is fixedly connected to the first follower frame 43.
[0075] Specifically, the first follower frame 43 can be equipped with slide rails at both ends along the horizontal direction, and the fixed frame 10 is connected through the slide rails. The first follower frame 43 can provide guidance for the vertical sliding of the first slider 41, making the sliding of the first slider 41 more stable.
[0076] Furthermore, the rotation and translation structure also includes a second follower frame 44; the second follower frame 44 is slidably disposed on the first follower frame 43 in the horizontal direction; one end of the rotating member 42 is rotatably disposed on the second follower frame 44 so as to connect the second slider 41 through the second follower frame 44 and the first follower frame 43.
[0077] In this embodiment, the first follower frame 43 and the second follower frame 44 together form the connecting member between the second slider 41 and the rotating member 42. Specifically, the rotating member 42 is rotatably connected to the second follower frame 44, while the second follower frame 44 can slide horizontally relative to the first follower frame 43, and the first follower frame 43 is fixedly connected to the second slider 41, so that the rotating member 42 can be rotatably and slidably connected to the second slider 41. That is, during the movement of the second slider 41 in the vertical direction, it can drive the first follower frame 43, the second follower frame 44, and one end of the rotating member 42 to move vertically. At the same time, since one end of the rotating member 42 needs to rotate around its own center, one end of the rotating member 42 will drive the second follower frame 44 to slide horizontally relative to the first follower frame 43.
[0078] In one embodiment, during the lifting and lowering of the first slider 31, the second slider 41 remains in its original horizontal position; during the lifting and lowering of the second slider 41, the first slider 31 remains in its original horizontal position.
[0079] Specifically, in this embodiment, during the process of the first slider 31 driving the scraping head 50 to rise and fall, the second slider 41 remains in its original horizontal position, so the scraping head 50 does not translate. During the process of the second slider 41 driving the scraping head 50 to translate horizontally, the first slider 31 remains in its original horizontal position, so the scraping head 50 does not rise or fall during horizontal translation. Therefore, in this embodiment, the area traversed by the scraping head 50 during its rising, falling, and translating processes on the coating is rectangular, which reduces the scraping head 50's abrasion of non-empty foil areas.
[0080] It should be noted that the above process can be achieved by controlling the undulating regions in the first annular curved track 22 and the second annular curved track 23.
[0081] In one embodiment provided in this application, please refer to Figures 1 to 7 The first circular curved road 22 includes a first high level section 221, a first low level section 222, a first uphill section 223, and a first downhill section 224. The second circular curved road 23 includes a second high level section 231, a second low level section 232, a second uphill section 233, and a second downhill section 234.
[0082] In this embodiment, in the vertical direction, the first uphill section 223, the first downhill section 224, the second uphill section 233, and the second downhill section 234 are all staggered, that is, they are not located on the same vertical line, so that the first slider 31 or the second slider 41 will not rise and fall synchronously.
[0083] Specifically, in this embodiment, when the first slider 31 is located in the first uphill section 223 or the first downhill section 224, the second slider 41 is located in the second high horizontal section 231 or the second low horizontal section 232; when the second slider 41 is located in the second uphill section 233 or the second downhill section 234, the first slider 31 is located in the first high horizontal section 221 or the first low horizontal section 222.
[0084] In practical applications, the operation process of the slurry scraping device provided in this embodiment can be as follows:
[0085] Initial state: The first slider 31 is located in the first low horizontal section 222, while the second slider 41 is located at the boundary between the second high horizontal section 231 and the second downhill section 234.
[0086] First stroke: Start the drive unit 20, which drives the rotating end 21 to rotate counterclockwise for the first stroke; within the first stroke, the first slider 31 is always located in the first low horizontal section 222, and the second slider 41 has completed the second downhill section 234 and is preparing to enter the second low horizontal section 232. Therefore, the horizontal height of the scraping head 50 remains unchanged. At the same time, the translation frame 40 drives the scraping head 50 to move horizontally, thereby scraping the blank area on the electrode surface.
[0087] Second stroke: The drive unit 20 starts, driving the rotating end 21 to rotate counterclockwise for the second stroke; within the second stroke, the first slider 31 completes the first uphill section 223 and prepares to enter the first high horizontal section 221, while the second slider 41 is located in the second low horizontal section 232. Therefore, the scraping head 50 remains in a horizontal position. At the same time, the lifting frame 30 drives the scraping head 50 to rise away from the electrode sheet, thereby avoiding the non-empty foil area of the electrode sheet.
[0088] In the third stroke, the drive unit 20 is activated, causing the rotating end 21 to rotate counterclockwise for the third stroke. During the third stroke, the first slider 31 is always located in the first high horizontal section 221, and the second slider 41 has completed the second uphill section 233 and is preparing to enter the second high horizontal section 231. Therefore, the horizontal height of the scraping head 50 remains unchanged. At the same time, the translation frame 40 drives the scraping head 50 to move horizontally, thereby resetting the horizontal position of the scraping head 50.
[0089] In the fourth stroke, the drive unit 20 is activated, causing the rotating end 21 to rotate counterclockwise in the third stroke. In the fourth stroke, the first slider 31 completes the first downhill section 224 and enters the first low horizontal section 222, while the second slider 41 is located in the second high horizontal section 231. Therefore, the scraping head 50 remains in a horizontal position. At the same time, the lifting frame 30 drives the scraping head 50 to descend to approach the electrode, thereby resetting the vertical position of the scraping head 50, that is, returning to the initial state mentioned above.
[0090] In this embodiment, the scraping head 50 can control the scraping of the electrode within a preset range, and there is no need to perform complex logic control on multiple drive units. This can reduce the scraping of non-empty foil areas, reduce device costs, simplify control logic, and reduce the delay in the lifting and horizontal movement of the scraping head 50.
[0091] In one implementation, the first slider 31 is provided with a roller extending into the first annular curved track 22. The second slider 41 is provided with a roller extending into the second annular curved track 23. This makes it easier for the first slider 31 and the second slider 41 to slide.
[0092] In one implementation, the scraping head 50 has a suction function. Specifically, the scraping head 50 can be connected to a suction pipe, which can suck the coating slurry into the waste system through the suction pipe while scraping the coating on the electrode surface.
[0093] A second aspect of this application provides a coating machine, including the slurry scraping device of any of the above.
[0094] Specifically, the coating machine also includes a sheet conveying device and a drying system. The sheet conveying device and drying system can utilize existing technologies, and therefore will not be described in detail in this embodiment.
[0095] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
