Description

Technical Field

[0001] This application relates to the field of coating machine technology, and in particular to a scraper mechanism, a method of using it, a coating machine, and lithium battery production equipment. Background Technology

[0002] In lithium battery production equipment, the coating machine is the core equipment for electrode preparation, and its primer coating process plays a crucial role in the uniformity of electrode coating thickness and surface quality. The doctor blade, as a core component of the primer coating unit, ensures the precision of slurry coating through continuous scraping. However, in actual production, the doctor blade mechanism requires frequent blade changes according to the different primer coating production needs of various customers. Currently, the primer coating doctor blade mechanism in related technologies generally uses manual blade changing, which not only leads to low blade changing efficiency and affects production capacity, but also easily results in uneven force on the doctor blade and poor clamping consistency, thus affecting the coating quality. Summary of the Invention

[0003] This application proposes a scraper mechanism to effectively solve the technical problems in related technologies, such as low efficiency of manual scraper changing, which easily affects coating quality.

[0004] This application also proposes a method of using the above-mentioned scraper mechanism.

[0005] This application also proposes a coating machine that includes the aforementioned scraper mechanism.

[0006] This application also proposes a lithium battery production equipment that includes the above-mentioned coating machine.

[0007] The first aspect of this application provides a scraper mechanism, including: a pusher plate, a clamping assembly, a driving component, and a blade storage assembly;

[0008] The pusher plate has a scraper groove, which is used to limit the use of the scraper;

[0009] The driving component is used to drive the pusher plate to move, thereby causing the scraper groove to switch between the working position and the tool changing position;

[0010] The blade storage assembly stores a replacement scraper, and the blade storage assembly is used to output the replacement scraper when the scraper groove reaches the blade changing position;

[0011] The clamping assembly is used to clamp the scraper when the scraper groove reaches the working position, and is also used to release the scraper to allow the scraper groove to switch its movement;

[0012] During the process of the drive component driving the pusher plate to switch from the working position to the blade changing position, the pusher plate and the scraper are relatively displaced, causing the scraper to disengage from the scraper groove.

[0013] Furthermore, the depth of the scraper groove is smaller than the thickness of the scraper, so that the top end of the scraper protrudes into the scraper groove. During the process of switching the pusher plate from the working position to the blade changing position, an external force is applied to the top end of the scraper to achieve a limit, so that the pusher plate and the scraper are relatively displaced.

[0014] Furthermore, the blade storage assembly has an output port for outputting the replacement scraper, the output port being positioned at a preset location to provide an external force acting on the tip of the scraper.

[0015] Furthermore, the pusher plate has a receiving surface for supporting the replacement scraper. The receiving surface and the scraper groove are spaced apart along the moving direction of the pusher plate. The receiving surface and the output port are used to cooperate to limit the replacement scraper. The output port provides an external force to the used scraper through the replacement scraper to be output, and outputs the replacement scraper into the scraper groove after the used scraper is dislodged from the scraper groove.

[0016] Furthermore, the clamping assembly includes a clamping component and a pressure plate, the clamping component being used to drive the pressure plate to move, and the pressure plate being arranged laterally perpendicular to the direction of movement of the pusher plate.

[0017] Furthermore, the clamping component includes a plurality of clamping members, each of which is connected to the pressure plate at a lateral interval.

[0018] Furthermore, the blade storage assembly includes a counterweight plate and a blade storage component. The blade storage component is used to store multiple replacement blades sequentially in a vertical direction. The bottom end of the blade storage component is used to output the replacement blades, and the top end of the blade storage component is used to place the counterweight plate. The counterweight plate is used to output the replacement blades sequentially.

[0019] And / or, the scraper mechanism further includes a waste blade groove for collecting the used scraper that has come off the scraper groove.

[0020] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects: the installation accuracy of the scraper is ensured by setting the scraper groove and the clamping component; the replacement scraper is stored by the scraper storage component; when the scraper needs to be replaced, the clamping component releases the scraper, and the pusher plate is driven to move by the drive component. During the movement, the pusher plate and the scraper are relatively displaced, causing the scraper to disengage from the scraper groove, and then the replacement scraper can be output to the scraper groove. Then the drive component and the clamping component are reset to complete the automatic scraper replacement, which greatly improves the efficiency of the primer coating part and ensures the coating quality.

[0021] A second aspect of this application provides a method for using a scraper mechanism, including the following steps:

[0022] The replacement scraper is stored in the blade storage assembly;

[0023] When changing the blade, the clamping assembly is loosened and the scraper is used;

[0024] The driving component drives the pusher plate to switch from the working position to the tool changing position;

[0025] During the movement of the pusher plate, the pusher plate and the scraper are relatively displaced, and the scraper disengages from the scraper groove.

[0026] The blade storage assembly outputs the replacement scraper into the scraper groove;

[0027] The driving component drives the pusher plate to switch from the tool changing position to the working position;

[0028] The clamping assembly clamps the replacement scraper, thus completing the scraper replacement.

[0029] A third aspect of this application provides a coating machine, including a scraper mechanism as described in the first aspect of this application.

[0030] The fourth aspect of this application provides a lithium battery production apparatus, including a coating machine as described in the third aspect of this application.

[0031] It is easy to understand that the method of using the scraper mechanism in the second aspect embodiment of this application, the coating machine in the third aspect embodiment of this application, and the lithium battery production equipment in the fourth aspect embodiment of this application all have the same technical effects as the scraper mechanism in the first aspect embodiment, and therefore will not be described again.

[0047] 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 embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application discloses a scraper mechanism, including a pusher plate 100, a clamping assembly 200, a driving component 300, and a blade storage assembly 400;

[0049] A scraper groove 110 is formed on the pusher plate 100, which is used to limit the use scraper 600. The drive component 300 is used to drive the pusher plate 100 to move, so as to drive the scraper groove 110 to switch between the working position and the scraper changing position. The scraper storage component 400 stores the replacement scraper 700 and is used to output the replacement scraper 700 when the scraper groove 110 reaches the scraper changing position. The clamping component 200 is used to clamp the use scraper 600 when the scraper groove 110 reaches the working position, and is also used to release the use scraper 600 so that the scraper groove 110 can switch movement. During the process of the drive component 300 driving the pusher plate 100 to switch from the working position to the scraper changing position, the pusher plate 100 and the use scraper 600 are relatively displaced, so that the use scraper 600 is dislodged from the scraper groove 110.

[0050] In the embodiments of this application, the installation accuracy of the scraper 600 is ensured by the scraper groove 110 and the clamping assembly 200. The replacement scraper 700 is stored by the scraper storage assembly 400. When a scraper needs to be changed, the clamping assembly 200 releases the scraper 600, and the pusher plate 100 is driven to move by the drive component 300. During the movement, the pusher plate 100 and the scraper 600 are relatively displaced, causing the scraper 600 to disengage from the scraper groove 110. Then, the replacement scraper 700 can be output to the scraper groove 110. Finally, the drive component 300 and the clamping assembly 200 are reset to complete the automatic scraper change, which greatly improves the efficiency of the primer coating and ensures the coating quality.

[0051] Understandably, in some embodiments, the scraper groove 110 of the pusher plate 100 limits the use scraper 600, and the clamping component 200 clamps the use scraper 600 in the working position to ensure installation accuracy, prevent scraper deviation during coating, and ensure the quality of the primer coating. The drive component 300 drives the pusher plate 100 to switch between the working position and the scraper changing position. When a scraper change is required, the pusher plate 100 switches from the working position to the scraper changing position to replace the old scraper with a new scraper. During the switching process, the pusher plate 100 and the use scraper 600 generate relative displacement, which allows the old scraper to be dislodged without manual disassembly, greatly improving the scraper changing efficiency and reducing downtime. The blade storage assembly 400 stores replacement blades 700. When the pusher plate 100 reaches the blade changing position, a new blade is output. The blade storage assembly 400 stores replacement blades 700 in advance and outputs them automatically during blade changing, realizing full automation of blade changing, reducing the intensity of manual operation, avoiding manual blade changing errors, and finally the drive component 300 and the clamping component 200 are reset to complete the automatic blade changing and ensure continuous coating operation.

[0052] It should be understood that during the process of the drive component 300 driving the pusher plate 100 to switch from the working position to the tool changing position, the pusher plate 100 and the scraper 600 undergo relative displacement, thereby disassembling the old scraper. In some embodiments, by additionally providing structural members arranged along the path, when the synchronously moving pusher plate 100 and scraper 600 reach the position of the structural member, the scraper 600 is subjected to the force of the structural member and is limited, thereby causing the pusher plate 100 and scraper 600 to separate relative to each other. For example, a fixed structural member can be provided through the pusher plate 100 so that when the pusher plate 100 moves to a preset position, the structural member protrudes from the pusher plate 100 and abuts against and limits the scraper 600. For example, structural components can be fixedly arranged around the pusher plate 100, and the pusher plate 100 and the scraper 600 can be offset in a certain direction, so that the structural components can contact the scraper 600 at a preset position to limit the movement of the pusher plate 100 without affecting the movement of the pusher plate 100, thereby achieving relative displacement between the pusher plate 100 and the scraper 600. In some embodiments, a movable pusher can also be provided at a preset position. When the pusher plate 100 moves to the preset position, the pusher is triggered to move to push the scraper 600, causing the scraper 600 to disengage from the scraper groove 110. In some embodiments, the structure or components of the scraper mechanism in this application can also be used, such as the frame of the scraper mechanism or the scraper storage assembly 400, etc., and their positions can be specifically designed to achieve a similar effect as the additional structural components in the above embodiments, thereby achieving the effect of providing a limiting force for the scraper 600 and achieving relative displacement between the pusher plate 100 and the scraper 600. It should be understood that by separating the pusher plate 100 from the scraper 600 along the movement path of the pusher plate 100, the scraper 600 is removed from the scraper groove 110, reducing the occurrence of machine stoppages during the connection of different actions, and improving production cycle time and production efficiency.

[0053] It is understood that the scraper groove 110 is used to limit the use scraper 600 and the replacement scraper 700 in place. To facilitate the scraper's disengagement from the scraper groove 110, an opening can be provided at one end of the scraper groove 110 closest to the working position. This allows the use scraper 600 to disengage from the opening when there is relative displacement between the pusher plate 100 and the use scraper 600. In other embodiments, this relative displacement can also be achieved by ejecting the scraper, allowing the use scraper 600 to disengage from the scraper groove 110. In some embodiments, a fixed inclined ejector can be provided to achieve the ejection of the use scraper 600 without affecting the switching motion. In some embodiments, a movable ejector can also be provided to allow for the ejection of the use scraper 600 and avoidance of the pusher plate 100, thus meeting the usage requirements.

[0054] Furthermore, the clamping assembly 200 is used to clamp the working scraper 600 on the scraper groove 110 and the replacement scraper 700 in place when in the working position. It is also used to release the working scraper 600 in time before the pusher plate 100 is driven by the drive component 300, so that the pusher plate 100 can perform normal switching movement. In some embodiments, the clamping assembly 200 can be a commonly used cylinder clamping mechanism, linkage clamping mechanism, cam-driven clamping mechanism, etc., so that the scraper can be clamped or released when subjected to driving force.

[0055] Furthermore, the replacement blades 700 can be output sequentially using gravity, or sequentially using a common blade distribution mechanism. Alternatively, they can be transferred and output using a transfer mechanism such as a suction cup or gripper in conjunction with a transmission mechanism such as a robotic arm or conveyor structure. Those skilled in the art can adapt the structure of the blade storage assembly 400 according to actual usage requirements to achieve the effect of storing a certain number of replacement blades 700 and outputting them sequentially at appropriate times. Thus, after the old working blade 600 is removed due to the relative displacement between the pusher plate 100 and the working blade 600, the replacement blades 700 can be promptly replenished into the blade slot 110 to complete automatic blade replacement, ensuring continuous coating operations.

[0056] In some embodiments, the scraper 600 can be understood as a scraper normally installed in the scraper groove 110 and capable of performing the primer coating process, and the replacement scraper 700 can be understood as a scraper disposed in the scraper storage assembly 400. When the replacement scraper 700 is output to the scraper groove 110 due to the scraper 600 being dislodged from it, the replacement scraper 700 is driven by the reset of the pusher plate 100 and pressed by the reset of the pressing assembly 200, and thus becomes a new scraper 600 to continue the primer coating process.

[0057] The following will combine Figures 1 to 4 The scraper mechanism disclosed in the embodiments of this application will be explained and described in detail.

[0058] It should be noted that, in order to make it easier to achieve relative displacement between the pusher plate 100 and the scraper 600, and to make the structure designed to achieve the corresponding technical effect simpler, in some embodiments of this application, the depth of the scraper groove 110 is smaller than the thickness of the scraper 600, so that the top end of the scraper 600 protrudes into the scraper groove 110. When the pusher plate 100 switches from the working position to the blade changing position, the top end of the scraper 600 is limited by an external force, so that the pusher plate 100 and the scraper 600 are relatively displaced.

[0059] Understandably, the blade groove 110 is designed with a depth less than the thickness of the working blade 600, allowing the top of the working blade 600 to protrude from the blade groove 110. This design does not affect the normal coating operation of the blade and provides a force point for limiting the blade during blade replacement. The structural design takes into account both working and blade replacement needs. When the drive component 300 drives the pusher plate 100 to switch from the working position to the blade replacement position and reach the preset position, an external force limits the protruding top of the blade, fixing the position of the working blade 600. This causes a relative displacement between the pusher plate 100 and the working blade 600, thereby allowing the working blade 600 to disengage from the blade groove 110, ensuring the smooth removal of the old blade. By utilizing the time interval during the operation to limit the top of the blade with external force, the relative displacement blade removal method does not require additional disassembly of components, further improving blade replacement efficiency, reducing downtime, and ensuring the continuity of primer coating operations.

[0060] In some embodiments, the pusher plate 100 is limited by an external force acting on the top of the scraper 600 during the transition from the working position to the blade changing position. Specifically, the external force can be provided by setting a structural component in a preset position, or by specifically designing the structure of the original components or modules of the scraper mechanism of this application to be set in a preset position to provide the external force.

[0061] In some specific embodiments, the blade storage assembly 400 has an output port 401 for outputting a replacement scraper 700. The output port 401 is set at a preset position to provide an external force acting on the tip of the working scraper 600. It is understood that the blade storage assembly 400 has an output port 401 for outputting the replacement scraper 700, and the output port 401 is fixed at the preset position. During blade replacement, the drive component 300 drives the pusher plate 100 to switch from the working position to the blade replacement position. During this process, the tip of the working scraper 600 protruding from the scraper groove 110 will contact the output port 401 at the preset position. The output port 401 applies a limiting external force to the tip of the scraper, fixing the position of the working scraper 600 and causing relative displacement between the pusher plate 100 and the working scraper 600, causing the old scraper to dislodge. Simultaneously, the output port 401 can output the replacement scraper 700, connecting the blade replacement process and taking into account both blade dislodgement limitation and new blade replenishment.

[0062] It should be understood that the tool storage assembly 400 of the scraper mechanism of this application provides external force, which on the one hand eliminates the need for additional limiting components, simplifies the mechanism structure, and reduces design and manufacturing costs; on the other hand, it can be linked with the subsequent action of the tool storage assembly 400 to lower and replace the scraper 700, further shortening the tool changing time and thus optimizing the entire automatic tool changing action.

[0063] In some embodiments, the blade storage assembly 400 can provide external force to limit the use of the scraper 600 through its own structure, such as the outer wall, the mounting component provided in the blade storage assembly 400, the limiting component, etc., or the external force can be provided through the replacement scraper 700 stored inside the blade storage assembly 400.

[0064] For example, in some embodiments, the pusher plate 100 has a receiving surface 120 for supporting the replacement scraper 700. The receiving surface 120 and the scraper groove 110 are spaced apart along the movement direction of the pusher plate 100. The receiving surface 120 and the output port 401 are used to cooperate to limit the replacement scraper 700. The output port 401 provides an external force to the working scraper 600 through the replacement scraper 700 to be output, and outputs the replacement scraper 700 into the scraper groove 110 after the working scraper 600 is removed from the scraper groove 110.

[0065] Understandably, the pusher plate 100 is provided with a receiving surface 120 spaced apart from the scraper groove 110 along the active direction, which is used to support the replacement scraper 700 to be output by the knife storage assembly 400. When changing the scraper, the pusher plate 100 switches to the scraper changing position, and the output port 401 cooperates with the receiving surface 120 to limit the replacement scraper 700. The top of the scraper 600 is in contact with the replacement scraper 700 to be output at the output port 401 of the knife storage assembly 400. The replacement scraper 700 acts as a medium to provide a limiting external force for the scraper 600, causing the pusher plate 100 and the scraper 600 to generate relative displacement and disengage. During the whole process, the replacement scraper 700 and the pusher plate 100 are relatively displaced until the replacement scraper 700 falls into the scraper groove 110, realizing automatic scraper changing while ensuring the accuracy and efficiency of scraper changing.

[0066] In some embodiments, the top of the scraper groove 110, the receiving surface 120, the top of the using scraper 600, and the top of the replacement scraper 700 have a height difference from low to high after installation. The bottom end of the replacement scraper 700 is slidably disposed on the receiving surface 120, and its outer periphery is limited by the output port 401 of the blade storage assembly 400, so that when the pusher plate 100 moves, the replacement scraper 700 can be relatively displaced with the pusher plate 100 and slide on the receiving surface 120. When the pusher plate 100 needs to change blades and is driven to move, the replacement scraper 700 slides on the receiving surface 120 until it contacts the top of the using scraper 600, then the using scraper 600 is pushed out of the scraper groove 110, and finally the replacement scraper 700 slides away from the receiving surface 120 and falls into the scraper groove 110, thereby realizing automatic blade changing.

[0067] In some embodiments of this application, the clamping assembly 200 includes a clamping component 210 and a pressure plate 220. The clamping component 210 drives the pressure plate 220 to move, and the pressure plate 220 is arranged laterally perpendicular to the direction of movement of the pusher plate 100. It is understood that the pressure plate 220 is arranged laterally perpendicular to the direction of movement of the pusher plate 100, and the clamping component 210 drives the pressure plate 220 to move. When the pusher plate 100 drives the scraper groove 110 to the working position, the pressure plate 220, driven by the clamping component 210, clamps the scraper 600 to ensure the scraper installation accuracy. When changing the scraper, the pressure plate 220, driven by the clamping component 210, releases the restriction on the scraper 600, ensuring that the pusher plate 100 can smoothly switch to the scraper changing position. The lateral arrangement of the pressure plate 220 ensures accurate and uniform clamping force, preventing the scraper from shifting during coating and ensuring installation accuracy and coating quality.

[0068] It should be understood that, to ensure the accuracy of automatic tool changing and adapt to the automated continuous tool changing process, in some specific embodiments, the clamping component 210 includes multiple clamping elements 211, each clamping element 211 being connected to the pressure plate 220 at lateral intervals. It can be understood that the clamping component 210 employs multiple clamping elements 211 arranged laterally at intervals, each connected to the pressure plate 220. By synchronously driving the pressure plate 220 at multiple points, the uniform clamping or loosening of the scraper is achieved. Combined with the pusher plate 100 and the scraper groove 110 structure, this ensures the scraper installation accuracy. The multi-point, spaced clamping arrangement ensures uniform force distribution on the pressure plate 220, resulting in a consistent distribution of the scraper clamping force to disperse the clamping load and avoid localized warping. The synchronized action further ensures the scraper installation accuracy and coating quality.

[0069] In some specific embodiments, the blade storage assembly 400 includes a counterweight plate 410 and a blade storage component 420. The blade storage component 420 is used to sequentially store multiple replacement scrapers 700 in a vertical direction. The bottom end of the blade storage component 420 is used to output the replacement scrapers 700, and the top end of the blade storage component 420 is used to place the counterweight plate 410. The counterweight plate 410 is used to output the replacement scrapers 700 sequentially. It can be understood that the blade storage component 420 stacks multiple replacement scrapers 700 in a vertical direction. The counterweight plate 410 is placed at the top of the blade storage component 420 and presses down on the stacked replacement scrapers 700 by its own weight, so that the scrapers are always pressed against the bottom output port 401, thereby realizing the automatic sequential output.

[0070] In some embodiments, multiple replacement scrapers 700 are vertically stacked and stored within the scraper storage component 420, increasing the scraper storage capacity, reducing the frequency of manual scraping, and improving continuous production capacity. The counterweight plate 410 relies on gravity to press down, ensuring that the replacement scrapers 700 are output in an orderly and smooth sequence. Gravity-fed scrapers eliminate the need for an additional drive component 300, reducing the complexity and cost of the mechanism.

[0071] In some specific embodiments, the scraper mechanism further includes a waste scraper groove 500 for collecting used scrapers 600 that have detached from the scraper groove 110. It is understood that after the old and new scrapers are replaced, the old scrapers fall into the waste trough, allowing for better recycling of the discarded scrapers.

[0072] The second aspect of this application discloses a method of using a scraper mechanism. The method of using the scraper mechanism can be the same as the method of using the scraper mechanism in the first aspect of this application. The method of using the scraper mechanism includes the following steps:

[0073] The replacement scraper 700 is stored in the blade storage assembly 400;

[0074] When changing the blade, loosen the clamping component 200 and use the scraper 600;

[0075] The drive unit 300 drives the pusher plate 100 to switch from the working position to the tool changing position;

[0076] During the movement of the pusher plate 100, the pusher plate 100 and the scraper 600 are relatively displaced, and the scraper 600 is dislodged from the scraper groove 110.

[0077] The blade storage assembly 400 outputs the replacement scraper 700 into the scraper groove 110;

[0078] The drive unit 300 drives the pusher plate 100 to switch from the tool changing position to the working position;

[0079] The clamping component 200 clamps and replaces the scraper 700, completing the blade replacement.

[0080] In some embodiments, the output port 401 of the blade storage assembly 400 and the supporting surface of the pusher plate 100 are used to limit the replacement scraper 700 to be output. During the movement of the pusher plate 100, the displacement of the pusher plate 100 causes the working scraper 600 to move synchronously. At this time, the replacement scraper 700 to be output is limited by the output port 401 and slides on the supporting surface. Since there is a height difference between the top of the scraper groove 110 and the top of the scraper, when the pusher plate 100 and the working scraper 600 move synchronously to the position of the replacement scraper 700 to be output, The replacement scraper 700 to be output will abut against the top of the working scraper 600 and limit it, while the pusher plate 100 is not affected by the replacement scraper 700 to be output and will move normally, causing the pusher plate 100 and the working scraper 600 to move relative to each other until the working scraper 600 is dislodged from the scraper groove 110 and falls off. Meanwhile, the replacement scraper 700 to be output slides on the support surface until it falls onto the scraper groove 110. Thus, after the old working scraper 600 is dislodged, the new replacement scraper 700 is promptly loaded into the scraper groove 110, realizing automatic scraper changing.

[0081] The scraper mechanism and its usage method according to a specific embodiment of this application are described in detail below. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0082] Understandably, existing scraper mechanisms rely on manual scraper changes based on customer primer production needs, resulting in high manufacturing costs due to the frequent scraper changes. However, the scraper mechanism of this application embodiment, compared to traditional manual scraper changes, reduces the number of personnel required for scraper changes, shortens the scraper change time, and achieves cost savings.

[0083] For some specific embodiments, see Figures 1 to 4 As shown, the scraper mechanism and usage method of this embodiment include the following scraper replacement process: First, 10 scrapers are stored in the scraper storage clamp, which serves as the scraper storage component 420. Since the depth of the scraper groove 110 is 0.3mm shallower than the scraper thickness, the position of the old scraper is 0.3mm higher than the scraper position in the scraper storage clamp. When the scraper needs to be replaced, the scraper replacement cylinder, which serves as the drive component 300, retracts. Due to the 0.3mm height difference between the new and old scrapers, the new scraper blocks the old scraper. When the scraper replacement cylinder retracts to its position, the old scraper, blocked by the new scraper, falls into the waste scraper groove 500. The new scraper is pressed into the scraper groove 110 by the counterweight plate 410. The scraper replacement cylinder extends and pushes the new scraper into place. Then, the scraper pressing cylinder, which serves as the pressing component 211, extends and presses the new scraper tightly, thus completing the scraper replacement. The positional accuracy of the new scraper is ensured by the scraper groove 110, and five cylinders are used in conjunction with the pressure plate 220 to directly press the scraper when pressing it. This ensures the lateral consistency of the scraper pressing and prevents some areas from not being pressed tightly.

[0084] Understandably, this mechanism is the base coating part of the coating machine in lithium battery production equipment. Its structure is different from the scraper structure of the conventional coating machine head. This scraper mechanism realizes the function of automatic scraper changing by moving the pusher plate 100 back and forth. It can also store a certain amount of scrapers to meet the scraper usage requirements within a certain period of time. The efficiency of the base coating part is greatly improved by automatically changing the scraper.

[0085] The coating machine according to the third aspect of this application includes: the scraper mechanism according to the first aspect of this application.

[0086] The fourth aspect of this application provides a lithium battery production equipment, including: a coating machine according to the third aspect of this application.

[0087] It is easy to understand that the method of using the scraper mechanism in the second aspect embodiment of this application, the coating machine in the third aspect embodiment of this application, and the lithium battery production equipment in the fourth aspect embodiment of this application all have the same technical effects as the scraper mechanism in the first aspect embodiment, and therefore will not be described again.
