Description

Technical Field

[0001] This application relates to the field of coating equipment technology, and in particular to a die head adjustment device and coating equipment. Background Technology

[0002] In related technologies, the position of the die head needs to be adjusted so that the distance between the die head and the back roller, and the lip opening defined by adjacent die heads, can be adjusted. However, it is difficult to quickly adjust the position of the die head, and there may be interference between the adjustment of the distance between the die head and the back roller and the adjustment of the lip opening, which will further increase the difficulty of adjusting the position of the die head. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of this application is to provide a die head adjustment device that can achieve rapid adjustment of the die head position and avoid interference between the adjustment of the distance between the die head and the back roller and the adjustment of the lip opening, thus making the adjustment of the die head position easier.

[0004] This application further proposes a coating device employing the aforementioned die adjustment device.

[0005] In a first aspect, this application provides a die head adjustment device, comprising: a mounting plate, an adjustment plate, and a spacing adjustment assembly. The mounting plate is disposed at one end of the length of the die head. The adjustment plate is movably disposed on the mounting plate along a first direction. The spacing adjustment assembly is disposed on the adjustment plate and is adapted to move synchronously with the adjustment plate. The spacing adjustment assembly is connected to the die head and is used to drive the die head to move along a second direction, wherein the first direction and the second direction form an angle. The adjusting plate moves along the first direction to adjust the lip opening, and the spacing adjusting component drives the die head to move along the second direction to adjust the spacing between the die head and the back roller.

[0006] According to the die head adjustment device of the present application embodiment, by setting up a mounting plate, an adjustment plate and a spacing adjustment component, on the one hand, the position adjustment of the die head in the first direction and the second direction is less likely to interfere, which can not only reduce the difficulty of die head position adjustment and increase the die head position adjustment speed, thereby reducing adjustment time, improving production efficiency and reducing production capacity waste, but also reduce the probability of the die head falling off during the adjustment process, which can reduce safety hazards. On the other hand, the structure of the die head adjustment device is simpler, which can reduce costs.

[0007] According to some embodiments of this application, the spacing adjustment assembly includes: an adjustment seat and a connecting block, the connecting block being connected to the mold head, the adjustment seat having an adjustment groove extending along a second direction, and the connecting block being slidably disposed within the adjustment groove.

[0008] In the above technical solution, on the one hand, the connecting block enables the die head to move along the inclined plane (i.e., the second direction), and the adjusting plate enables the die head to move in the vertical direction, thereby enabling precise adjustment of the lip opening and the distance between the lip and the back roller; on the other hand, the connecting block can be directly connected to the end of the die head to realize the corresponding die head position adjustment, making the structure of the spacing adjustment component simpler, and it can be directly fixed on the existing die head to realize the modification of the coating equipment, which can reduce the modification difficulty and reduce the cost of the coating equipment.

[0009] According to some embodiments of this application, the spacing adjustment assembly further includes an adjustment member, which is rotatably disposed on an adjustment seat, and one end of the rod of the adjustment member extends into the adjustment groove to push against the connecting block.

[0010] In the above technical solution, on the one hand, the distance between the lip and the back stick can be adjusted by rotating the adjusting component, which can reduce the difficulty of adjustment and improve the efficiency of adjustment. On the other hand, the rotation adjustment is more controllable and can further reduce the difficulty of adjusting the distance between the lip and the back stick in the second direction.

[0011] According to some embodiments of this application, the adjustment element is constructed as a micrometer.

[0012] In the above technical solution, the high-precision threaded transmission of the micrometer can achieve micron-level back roller distance adjustment accuracy, which can improve the adjustment accuracy of the die head adjustment device.

[0013] According to some embodiments of this application, the spacing adjustment assembly further includes a reset member, which is disposed on the adjustment seat and is used to apply a force opposite to that of the adjustment member.

[0014] In the above technical solution, by setting a reset component, the reset component and the adjustment component cooperate with the connecting block on both sides of the connecting block in the second direction, which can improve the position adjustment accuracy of the connecting block in the second direction and enable the connecting block to reset in time, reducing the difficulty of reset. At the same time, the reset structure of the connecting block is simpler, which can further simplify the structure of the spacing adjustment component and reduce the cost.

[0015] According to some embodiments of this application, the reset member is constructed as a linear spring, the adjusting member pushes against the connecting block at one end of the connecting block, and the reset member pushes against the connecting block at the other end of the connecting block.

[0016] In the above technical solution, by constructing the reset component as a linear spring, the difficulty of setting the reset component can be further reduced, and the reset force provided by the reset component can be more linear. This can reduce the probability of excessive or insufficient reset force, and also improve the working stability and reliability of the spacing adjustment component.

[0017] According to some embodiments of this application, the die head adjustment device further includes: a first limiting member, which is disposed on the adjustment seat and extends into the adjustment groove at one end, and is adapted to push the limiting connecting block upward in a third direction, wherein the first direction, the second direction and the third direction have an included angle with each other.

[0018] In the above technical solution, on the one hand, the connecting block can fit into the adjustment groove, which can improve the adjustment accuracy of the die head in the second direction. On the other hand, it can serve as a dangerous redundancy structure. After emergency operation, it can limit the die head and reduce the probability of the die head coming out, thereby further reducing the safety hazards of the coating equipment.

[0019] According to some embodiments of this application, a second limiting member is provided on the connecting block, and a limiting groove that cooperates with the second limiting member is provided on the mounting plate. When the spacing adjustment component is at its maximum stroke, the second limiting member is located in the limiting groove and pushes against the bottom of the limiting groove.

[0020] In the above technical solution, by setting the limiting groove, on the one hand, the movement stroke of the connecting block can be controlled, which can reduce the probability of over-adjustment of the spacing adjustment component, thereby reducing the probability of structural damage to the spacing adjustment component and extending the service life of the die head adjustment device. On the other hand, the first limiting member and the second limiting member can cooperate to limit the die head at the second extreme position, which can further reduce the probability of the die head detaching, thereby reducing safety hazards in the die head adjustment process.

[0021] According to some embodiments of this application, the first limiting member and the second limiting member are located on both sides of the connecting block in the third direction.

[0022] In the above technical solution, the cooperation of the first limiting component and the second limiting component provides emergency operation capability in case of failure of the die head adjustment device, enhances the maintainability and reliability of the coating equipment, and can constrain the movement stroke of the connecting block, reduce the probability of mechanical damage caused by misoperation or over-adjustment, and extend the service life of the die head adjustment device.

[0023] According to some embodiments of this application, a first guide member is provided on the mounting plate, and a second guide member is provided on the adjustment plate that slides in cooperation with the first guide member.

[0024] In the above technical solution, the limiting and guiding structure between the mounting plate and the adjusting plate consists of a first guide member and a second guide member. One of the first guide member and the second guide member can be a slider, and the other can be a guide rail. The cross-sectional shape of the guide rail can be rectangular, T-shaped, or dovetail-shaped. T-shaped and dovetail-shaped guide rail structures have good anti-disengagement performance. A guide groove adapted to the cross-sectional shape of the guide rail is provided on the corresponding pressure block. Stops or limiting surfaces can be provided at both ends of the guide groove to limit the movement stroke of the adjusting plate, prevent the adjusting plate from disengaging from the mounting plate, improve the fit stability, and extend the service life. According to some embodiments of this application, the travel distance of the adjustment plate is 5mm-20mm.

[0025] In the above technical solution, by making the movement stroke of the adjustment plate within the range of 5mm-20mm, on the one hand, it can avoid the movement stroke of the adjustment plate being too small, so that the lip opening adjustment effect can be improved through a reasonable movement stroke. On the other hand, it can avoid the movement stroke of the adjustment plate being too large, so as to avoid the failure of the inclined surface fit between the two mold heads due to the excessive movement stroke.

[0026] According to some embodiments of this application, the adjustment plate is provided with a third limiting member, and the mounting plate has a limiting hole that cooperates with the third limiting member. When the adjustment plate is at its maximum stroke, the third limiting member is adapted to be inserted into the limiting hole.

[0027] In the above technical solution, the adjustment plate can be limited to the fourth extreme position by the cooperation of the third limiting member and the limiting hole, thereby improving the fixing stability of the adjustment plate, reducing the probability of the adjustment plate and the spacing adjustment component as a whole detaching from the mounting plate, further improving structural stability, and further reducing safety hazards.

[0028] According to some embodiments of this application, a fourth limiting member is provided at the end of the mounting plate in a first direction. The fourth limiting member protrudes from the mounting plate and extends toward the side where the adjusting plate is located, and is adapted to push against the limiting adjusting plate at the end of the adjusting plate when the adjusting plate is at its maximum stroke.

[0029] In the above technical solution, a redundant limiting structure can be formed by the fourth limiting member. During the adjustment process, if the third limiting member fails or is not installed in the limiting hole, the fourth limiting member can support the adjustment plate from below, thereby reducing the probability of the adjustment plate coming off the mounting plate and further reducing safety hazards.

[0030] According to some embodiments of this application, a drive module is provided on the mounting plate, which is used to drive the adjustment plate to move relative to the mounting plate.

[0031] In the above technical solution, the mold head adjustment device can achieve automated adjustment in at least the first direction, which can further reduce the difficulty of adjustment and improve the adjustment efficiency.

[0032] Secondly, this application provides a coating apparatus, including: the die head adjustment device and the die head as described in the above embodiments, wherein there are at least two die heads, an opening is defined between adjacent die heads, and at least one of the two die heads defining the same opening is provided with the die head adjustment device.

[0033] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0046] A single battery cell can be a rechargeable battery. A rechargeable battery is a battery cell that can be recharged after it has been discharged, allowing the active materials to be activated and the cell to continue to be used.

[0047] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0048] In some embodiments, a battery cell may include a housing, an end cap, and an electrode assembly. The housing defines an accommodating space with an installation opening. The housing may be a pouch structure that wraps around the electrode assembly of a pouch battery, or it may be constructed as a rigid shell structure in which the electrode assembly is disposed.

[0049] The housing is a component used to fit with the end cap to form the internal environment of a battery cell. This internal environment can house electrode components, electrolyte, and other parts. The housing and end cap can be separate components. A mounting opening can be provided on the housing, and the end cap closes the opening at the mounting opening to form the internal environment of the battery cell. The housing can be of various shapes and sizes, such as cuboid, cylindrical, hexagonal prism, etc.

[0050] The housing may contain one or more electrode assemblies.

[0051] The electrode assembly is mainly formed by winding or stacking positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The portions of the positive and negative electrode sheets containing active material constitute the main body of the electrode assembly, while the portions without active material each constitute a tab. The positive and negative tabs can be located together at one end of the main body or at opposite ends of the main body. During the charging and discharging process of the battery, the positive and negative active materials react with the electrolyte, and the tabs connect to the electrode terminals to form a current loop.

[0052] In some embodiments of this application, the positive electrode sheet includes a positive electrode active material. Optionally, the positive electrode sheet includes a positive electrode film layer containing the positive electrode active material. As an example, the positive electrode sheet also includes a positive electrode current collector, with the positive electrode film layer disposed on the positive electrode current collector; in another example, the positive electrode sheet is a self-supporting structure, comprising only the positive electrode film layer without a positive electrode current collector. Further, the positive electrode film layer also includes a conductive agent and a binder. In the positive electrode sheet, the conductive agent includes at least one of carbon black, graphite, carbon nanotubes (CNTs), graphene, and carbon fiber; the binder includes polyvinylidene fluoride (PVDF); the positive electrode current collector includes aluminum foil; and the positive electrode active material includes at least one of lithium iron phosphate, lithium manganese iron phosphate, lithium nickel manganese oxide, lithium cobalt oxide, lithium-rich manganese-based oxide, and lithium manganese oxide.

Optionally, the negative electrode sheet includes a negative electrode film layer containing the negative electrode active material. As an example, the negative electrode sheet also includes a negative electrode current collector, with the negative electrode film layer disposed on the negative electrode current collector; in another example, the negative electrode sheet is a self-supporting structure, comprising only the negative electrode film layer without a negative electrode current collector.

Optionally, the negative electrode active material includes lithium metal, and the negative electrode is a lithium metal negative electrode.

[0054] Currently, the conventional manufacturing process of electrode sheets (positive or negative electrode sheets) consists of multiple steps such as coating, drying, rolling, and slitting. In the coating process, the prepared viscous slurry is uniformly, continuously or intermittently coated onto the film layer (positive or negative electrode film layer) using coating equipment. Single, double or multiple layers of slurry can be coated onto the film surface by using an extrusion die to form a coating layer.

[0055] For example, if there are two dies forming a lip, a single layer of slurry is applied to the film surface. If there are three or more dies forming two or more corresponding lips, double or multiple layers of slurry are applied to the film surface. That is, a lip is formed between adjacent dies, and the film travels on the back roller to apply slurry to the film through the lip.

[0056] In related technologies, the position of the die head needs to be adjusted so that the distance between the die head and the back roller, and the lip opening defined by adjacent die heads, can be adjusted. However, it is difficult to quickly complete the die head position adjustment, and there may be interference between the adjustment of the distance between the die head and the back roller and the adjustment of the lip opening, which will further increase the difficulty of adjusting the die head position.

[0057] Based on this, this application proposes a die head adjustment device. The spacing adjustment component is connected to the die head and is also connected to an adjustment plate. The adjustment plate can move relative to the mounting plate in a first direction to adjust the lip opening. The spacing adjustment component can drive the die head to move in a second direction to adjust the spacing between the die head and the back roller. On the one hand, by adjusting the position of the adjustment plate relative to the mounting plate in the first direction and adjusting the position of the die head in the second direction through the spacing adjustment component, the probability of interference between lip opening adjustment and the distance adjustment between the die head and the back roller can be reduced, and the difficulty of die head position adjustment can be reduced. On the other hand, it can realize rapid position adjustment of the die head, reduce safety hazards during the adjustment process, simplify the structure of the die head adjustment device, and reduce costs.

[0058] Below, in conjunction with Figures 1-9 The specific structure of the mold head adjustment device 100 in the embodiments of this application will be described.

[0059] like Figure 1 and Figure 2 As shown, the mold head adjustment device 100 of this application embodiment includes: mounting plate 10, adjustment plate 20, spacing adjustment component 30, first limiting member 40, second limiting member 50, third limiting member 60 and fourth limiting member 70.

[0060] The mounting plate 10 is fixed on the frame, and mounting plates 10 are provided at both ends of the length of the die head. The spacing adjustment component 30 is installed on the mounting plate 10, and the die head is connected to the spacing adjustment component 30 to realize the installation of the die head on the frame. The mounting plate 10 has a first guide 11 and a limiting hole 12. The adjustment plate 20 has a second guide 21. The spacing adjustment component 30 has an adjustment seat 31, a connecting block 32, an adjustment component 33, and a reset component 34. The adjustment seat 31 has an adjustment groove 311.

[0061] Combination Figure 8 and Figure 9 As shown, the first guide member 11 and the second guide member 21 are slidably engaged in the first direction. For example, one of the first guide member 11 and the second guide member 21 is constructed as a T-shaped groove, and the other is constructed as a T-shaped guide rail, so that the position adjustment plate 20 relative to the mounting plate 10 can be realized through the guiding engagement of the first guide member 11 and the second guide member 21.

[0062] Furthermore, such as Figures 3-7 As shown, the adjusting seat 31 is provided with an adjusting groove 311, which extends along the second direction. The connecting block 32 is connected to the mold head 200 and is movably disposed in the adjusting groove 311. At least a portion of the adjusting member 33 extends into the adjusting groove 311 and pushes against the connecting block 32 at one end in the second direction. The resetting member 34 pushes against the connecting block 32 at the other end in the second direction. The connecting block 32 is pushed against the bottom surface of the adjusting groove 311 (on one side of the third direction). The first limiting member 40 pushes against the connecting block 32 on the other side of the third direction to limit the movement direction of the connecting block 32 and prevent the connecting block 32 from coming out of the adjusting groove 311.

[0063] The connecting block 32 cooperates with the first limiting member 40 on one side of the third direction, and the connecting block 32 is provided with a second limiting member 50 on the other side of the third direction. The mounting plate 10 is provided with a limiting groove 13, and the second limiting member 50 is located in the limiting groove 13. The limiting groove 13 can prevent the connecting block 32 and the mold head 200 from coming out.

[0064] The third limiting member 60 is disposed on the adjusting plate 20 and is adapted to extend into the limiting hole 12 of the mounting plate 10 to limit the spacing adjustment component 30 and the adjusting plate 20 in the first direction. The fourth limiting member 70 is disposed on the mounting plate 10 and is located below one end face of the adjusting plate 20 in the first direction, and can also be used to limit the spacing adjustment component and the adjusting plate 20.

[0065] It should be noted that the mold head 200 is prone to slurry blockage during use. When it is necessary to clean or reposition the mold head 200, one of the multiple mold heads 200 needs to be disassembled, which is a complicated and time-consuming process and poses a safety hazard.

[0066] In addition, the adjustment of the lip opening and the distance between the die head and the back roller needs to be done manually, resulting in low adjustment accuracy.

[0067] Specifically, when it is necessary to adjust the coating weight, the distance between the die head 200 and the back roller, and the lip opening, these adjustments need to be done manually. On the one hand, the precision is low, making it difficult to ensure coating uniformity and consistency, which will affect the coating quality. On the other hand, each adjustment takes a long time, which will reduce production efficiency and cause a waste of production capacity.

[0068] More importantly, the existing position adjustment structure is complex, costly, and difficult to maintain.

[0069] It should be noted that adjusting the position in the first direction allows for adjustment of the opening of the lips themselves, while adjusting the position in the second direction allows for adjustment of the distance between the lips and the back stick.

[0070] This application, by setting an adjustment plate 20 that is movable along the first direction, and by connecting the spacing adjustment component 30 to the die head 200 and fixing it on the adjustment plate 20, allows the position of the die head 200 to be adjustable in both the first and second directions, which reduces the difficulty of adjustment. In the event of slurry blockage, the die head 200 will not fall off during the adjustment process, reducing safety hazards. Furthermore, by constructing the adjustment component 33 as a micrometer, the adjustment accuracy can be improved, thereby improving coating uniformity and consistency, increasing adjustment efficiency, reducing adjustment time, improving production efficiency, and reducing capacity waste. At the same time, the structure of the die head adjustment device 100 is simpler, which can reduce costs and reduce maintenance difficulty.

[0071] The following is for reference. Figures 1-10 The present application describes a die head adjustment device 100 and a coating apparatus 300 according to embodiments thereof.

[0072] like Figure 1 and Figure 2 As shown, this application provides a mold head adjustment device 100, including: a mounting plate 10, an adjustment plate 20, and a spacing adjustment assembly 30.

[0073] Combination Figure 1 , Figure 2 as well as Figure 10As shown, the mounting plate 10 is disposed at one end of the length of the mold head 200, the adjusting plate 20 is movably disposed on the mounting plate 10 along the first direction, the spacing adjusting component 30 is disposed on the adjusting plate 20 and is adapted to move synchronously with the adjusting plate 20, the spacing adjusting component 30 is connected to the mold head 200 and is used to drive the mold head 200 to move along the second direction, the first direction and the second direction having an angle.

[0074] It should be noted that the adjusting plate 20 moves along the first direction to adjust the lip opening, and the spacing adjusting component 30 drives the die head 200 to move along the second direction to adjust the spacing between the die head 200 and the back roller.

[0075] Specifically, at least two die heads 200 define the lip opening, and the mating areas of the two die heads 200 form mutually matching inclined structures. A spacing adjustment component 30 is provided on the adjustment plate 20, and the spacing adjustment component 30 is connected to the die head 200. Thus, during the movement of the adjustment plate 20 relative to the mounting plate 10, the die head 200 connected to the spacing adjustment component 30 on the adjustment plate 20 can be driven to move, thereby realizing the position adjustment between the two die heads 200 to achieve the adjustment of the lip opening. The two mutually matching inclined structures define the lip opening, and when the spacing adjustment component 30 further drives the die head 200 to move relative to the other die head 200, the position adjustment between the die head 200 and the back roller can be achieved.

[0076] Furthermore, the adjustment plate 20 can move relative to the mounting plate 10 in the first direction, and the inclined surface mating structure between the two mold heads 200 can convert the movement of the adjustment plate 20 in the first direction into the normal movement of the mold head 200, so as to realize the adjustment of the lip opening.

[0077] Understandably, by setting up the mounting plate 10, the adjustment plate 20, and the spacing adjustment component 30, the adjustment of the lip opening and the distance between the lip and the back roller can be shortened from several hours (involving tedious steps such as disassembly, flipping, and installation) to a few minutes. The operator only needs to adjust the spacing adjustment component 30 and / or adjust the relative position of the adjustment plate 20 and the mounting plate 10 to complete the adjustment without disassembling the mold head 200. During the position adjustment process, the mold head 200 is always fixed on the adjustment plate 20 by the spacing adjustment component 30, which can eliminate the safety risks caused by the mold flipping operation.

[0078] Furthermore, the spacing adjustment component 30 adjusts the distance between the lip and the back roller along the second direction, and the adjustment plate 20 moves along the first direction to adjust the lip opening, so that the die head adjustment device 100 has two degrees of freedom, and the two degrees of freedom are independent of each other and do not interfere with each other, which can meet different process adjustment requirements respectively.

[0079] Among them, the lip opening mainly affects the coating thickness and uniformity, while the distance between the die head 200 and the back roller (i.e., the distance between the lip and the back roller) mainly affects the coating gap and coating edge effect. Together, they can cover a wider coating process window.

[0080] According to the embodiment of this application, the die head adjustment device 100, by setting the mounting plate 10, the adjustment plate 20 and the spacing adjustment component 30, on the one hand, the position adjustment of the die head 200 in the first direction and the second direction is less likely to cause interference. This not only reduces the difficulty of adjusting the position of the die head 200 and increases the position adjustment speed of the die head 200, thereby reducing the adjustment time, improving production efficiency and reducing production capacity waste, but also reduces the probability of the die head 200 falling off during the adjustment process, which can reduce safety hazards. On the other hand, it makes the structure of the die head adjustment device 100 simpler and reduces costs.

[0081] like Figure 3 , Figure 4 and Figure 5 As shown, according to some embodiments of this application, the spacing adjustment assembly 30 includes: an adjustment seat 31 and a connecting block 32. The connecting block 32 is connected to the mold head 200. The adjustment seat 31 has an adjustment groove 311 that extends along a second direction. The connecting block 32 is slidably disposed in the adjustment groove 311.

[0082] Specifically, the two mold heads 200 are connected by a bevel structure to define the lip. The extension direction of the adjustment groove 311 is consistent with the extension direction of the bevel. The connecting block 32 is located at the end of the length direction of the mold head 200 and is connected to the mold head 200. The connecting block 32 is set in the adjustment groove 311 so that when the connecting block 32 moves in the second direction in the adjustment groove 311, it can synchronously drive the mold head 200 to move in the second direction, so as to realize the relative position adjustment between the two bevels, and thus realize the adjustment of the distance between the lip and the back roller.

[0083] In this way, on the one hand, the connecting block 32 enables the die head 200 to move along the inclined plane (i.e., the second direction), and the adjusting plate 20 enables the die head 200 to move in the vertical direction, thereby enabling precise adjustment of the lip opening and the distance between the lip and the back roller; on the other hand, the connecting block 32 can be directly connected to the end of the die head 200 to achieve the corresponding position adjustment of the die head 200, making the structure of the spacing adjustment component 30 simpler, and it can be directly fixed on the existing die head 200, which can realize the modification of the coating equipment 300, reduce the modification difficulty, and reduce the cost of the coating equipment 300.

[0084] Combination Figure 6 and Figure 7As shown, according to some embodiments of this application, the spacing adjustment assembly 30 further includes an adjustment member 33, which is rotatably disposed on the adjustment seat 31, and one end of the rod of the adjustment member 33 extends into the adjustment groove 311 to push against the connecting block 32.

[0085] Specifically, the adjusting seat 31 may be provided with a threaded hole, and the rod of the adjusting member 33 may be provided with an external thread, so that the rod and the adjusting seat 31 form a threaded transmission. The length of the part of the rod extending into the adjusting groove 311 can be adjusted by rotating the end of the adjusting member 33. The rod pushes against the connecting block 32. By adjusting the length of the part of the rod extending into the adjusting groove 311, the position of the connecting block 32 in the adjusting groove 311 can be adjusted accordingly.

[0086] In this way, on the one hand, the distance between the lip and the back stick can be adjusted by rotating the adjusting component 33, which can reduce the difficulty of adjustment and improve the efficiency of adjustment. On the other hand, the rotation adjustment is more controllable and can further reduce the difficulty of adjusting the distance between the lip and the back stick in the second direction.

[0087] For example, adjustment element 33 is constructed as a micrometer.

[0088] In other words, the high-precision rotation of the adjusting component 33 can drive the die head 200 to produce a slight displacement along the preset inclined plane direction. The two adjacent die heads 200 are connected by the inclined plane. When the die head 200 is slightly displaced along the inclined plane, the distance between the lip and the back roller can be changed with high precision. That is, the distance between the lip and the back roller can be adjusted at the micron level by using the high precision and high resolution characteristics of the micrometer.

[0089] In this way, the high-precision threaded transmission of the micrometer can achieve micron-level back roller distance adjustment accuracy, which can improve the adjustment accuracy of the die head adjustment device 100.

[0090] In some embodiments, an adjustment scale can be set on the adjustment seat 31 to make the adjustment value reading of the adjustment component 33 more intuitive, and the adjustment amount can be quantified and recorded each time, which is conducive to the standardization of process parameters and makes the adjustment amount traceable.

[0091] For example, the scale of a micrometer is typically 0.5 mm or 0.01 mm per revolution, which can achieve micron-level or even higher precision in fine-tuning of the distance between the lip and the back roller.

[0092] Further integration Figure 7 As shown, according to some embodiments of this application, the spacing adjustment assembly 30 further includes a reset member 34, which is disposed on the adjustment seat 31 and is used to apply a force opposite to that of the adjustment member 33.

[0093] The spacing adjustment assembly 30 includes a reset member 34, an adjustment seat 31, a connecting block 32, and an adjustment member 33. The reset member 34 can provide pre-tightening force and reset force to the connecting block 32 on one side of the connecting block 32 in the second direction, while the adjustment member 33 can push against the connecting block 32 on the other side of the second direction so that the die head 200 can always keep in contact with the adjustment member 33, thereby reducing the mechanical gap between the adjustment member 33 and the connecting block 32.

[0094] In this way, by setting the reset component 34, which cooperates with the adjustment component 33 on both sides of the connecting block 32 in the second direction, the position adjustment accuracy of the connecting block 32 in the second direction can be improved, and the connecting block 32 can be reset in time, reducing the difficulty of reset. At the same time, the reset structure of the connecting block 32 is simpler, which can further simplify the structure of the spacing adjustment component 30 and reduce the cost.

[0095] Furthermore, the spacing adjustment component 30 may also include a cover plate, which can be placed on the connecting block 32 and the adjusting seat 31 to provide structural protection for the connecting block 32, the adjusting seat 31 and the adjusting component 33, and improve aesthetics.

[0096] like Figure 7 As shown, according to some embodiments of this application, the reset member 34 is constructed as a linear spring, the adjusting member 33 pushes against the connecting block 32 at one end of the connecting block 32, and the reset member 34 pushes against the connecting block 32 at the other end of the connecting block 32.

[0097] Specifically, a blind hole can be provided on the adjusting seat 31, which is connected to the adjusting groove 311. A linear spring is provided in the blind hole so that the reset member 34 can push against the connecting block 32 at the other end of the connecting block 32.

[0098] The linear spring can eliminate the mechanical gap between the connecting block 32 and the adjusting member 33.

[0099] In other words, there is an unavoidable mechanical gap between the adjusting component 33 and the connecting block 32, and between the connecting block 32 and the inclined surface of the die head 200. The linear spring, by applying a continuous preload, keeps the contact surfaces of the connecting block 32 and the adjusting component 33 in contact, eliminating the backlash error and adjustment dead zone caused by the mechanical gap. At the same time, it can provide the reset force of the connecting block 32. That is, when the adjusting component 33 rotates in the opposite direction, the reset force of the linear spring pushes the connecting block 32 and the die head 200 to reset following the movement of the adjusting component 33, ensuring the consistency of the bidirectional response of the adjustment action. It can also achieve vibration damping. In the high-speed vibration environment of the coating equipment 300, the linear spring plays a certain role in vibration damping and can reduce the change in the distance between the lip and the back roller caused by vibration.

[0100] Therefore, by constructing the reset member 34 as a linear spring, the difficulty of setting up the reset member 34 can be further reduced, and the reset force provided by the reset member 34 can be more linear. This can reduce the occurrence of excessive or insufficient reset force, and also improve the working stability and reliability of the spacing adjustment assembly 30.

[0101] It should be noted that by integrating the adjustment component 33, adjustment plate 20, mounting plate 10, reset component 34, etc. into the limited space at the length end of the die head 200, a compact and modular die head adjustment device 100 can be formed. The die head adjustment device 100 can be directly installed on the existing die head 200 without changing the main structure of the existing coating equipment 300, and has good compatibility and modifiability.

[0102] like Figures 3-7 As shown, according to some embodiments of this application, the mold head adjustment device 100 further includes: a first limiting member 40, which is disposed on the adjustment seat 31 and extends into the adjustment groove 311 at one end, and is adapted to push the limiting connecting block 32 in a third direction upward, wherein the first direction, the second direction and the third direction have an angle with each other.

[0103] It should be noted that the first direction is the height direction, the up and down direction, the second direction is the direction of the inclined plane that defines the lip, and the third direction is perpendicular to the second direction.

[0104] Specifically, the first limiting member 40 is used to push the connecting block 32 upward from the third side so that the connecting block 32 can fit into the adjustment groove 311. At the same time, when the spacing adjustment component 30 malfunctions or requires quick manual intervention, the operator can use the first limiting member 40 to perform emergency operation, press and fix the connecting block 32 into the adjustment groove 311, thereby limiting the mold head 200 and reducing the probability of the mold head 200 coming off.

[0105] In this way, on the one hand, the connecting block 32 can fit into the adjustment groove 311, which can improve the adjustment accuracy of the die head 200 in the second direction. On the other hand, it can serve as a dangerous redundancy structure. After emergency operation, it can limit the die head 200, which can reduce the probability of the die head 200 coming off, thereby further reducing the safety hazards of the coating equipment 300.

[0106] According to some embodiments of this application, a second limiting member 50 is provided on the connecting block 32, and a limiting groove 13 that cooperates with the second limiting member 50 is provided on the mounting plate 10. When the spacing adjustment component 30 is at its maximum stroke, the second limiting member 50 is located in the limiting groove 13 and pushes against the bottom of the limiting groove 13.

[0107] Specifically, the connecting block 32 can be generally cylindrical and extends into the adjustment groove 311. The connecting block 32 has two opposite sides in the third direction. The first limiting member 40 pushes against one side, and a second limiting member 50 is provided on the other side. The second limiting member 50 extends away from the connecting block 32 in the third direction. A limiting groove 13 is correspondingly provided on the mounting plate 10. The connecting block 32 has a first limit position and a second limit position in the second direction in the adjustment groove 311. In the second limit position, the second limiting member 50 is located in the limiting groove 13 so that the limiting groove 13 can limit the limit position of the connecting block 32.

[0108] In this way, by setting the limiting groove 13, on the one hand, the movement stroke of the connecting block 32 can be controlled, which can reduce the probability of over-adjustment of the spacing adjustment component 30, thereby reducing the probability of structural damage to the spacing adjustment component 30 and extending the service life of the mold head adjustment device 100. On the other hand, the first limiting member 40 and the second limiting member 50 are located on both sides of the connecting block 32 in the third direction. The first limiting member 40 and the second limiting member 50 can cooperate to limit the mold head 200 at the second extreme position, which can further reduce the probability of the mold head 200 disengaging, thereby reducing the safety hazards during the adjustment process of the mold head 200.

[0109] In summary, the cooperation of the first limiting member 40 and the second limiting member 50 provides emergency operation capability in case of failure of the die head adjustment device 100, enhances the maintainability and reliability of the coating equipment 300, and can constrain the movement stroke of the connecting block 32, reducing the probability of mechanical damage caused by misoperation or over-adjustment, and extending the service life of the die head adjustment device 100.

[0110] like Figure 8 and Figure 9 As shown, according to some embodiments of this application, the mounting plate 10 is provided with a first guide member 11, and the adjusting plate 20 is provided with a second guide member 21 that slides with the first guide member 11.

[0111] Specifically, the limiting and guiding structure between the mounting plate 10 and the adjusting plate 20 consists of a first guide member 11 and a second guide member 21. One of the first guide member 11 and the second guide member 21 can be a slider, and the other can be a guide rail. The cross-sectional shape of the guide rail can be rectangular, T-shaped, or dovetail-shaped. The T-shaped and dovetail-shaped guide rail structures have good anti-disengagement performance. A guide groove that matches the cross-sectional shape of the guide rail is provided on the mounting plate 10. The two ends of the guide groove can be provided with blocks or limiting surfaces to limit the movement stroke of the adjusting plate 20, prevent the adjusting plate 20 from disengaging from the mounting plate 10, improve the fit stability, and extend the service life.

[0112] According to some embodiments of this application, the travel distance of the adjustment plate 20 is 5mm-20mm.

[0113] For example, the travel of the adjustment plate 20 can be 5mm, 7mm, 12mm, 15mm, 18mm, 20mm, etc.

[0114] In this way, by keeping the movement stroke of the adjusting plate 20 within the range of 5mm-20mm, on the one hand, the movement stroke of the adjusting plate 20 can be avoided from being too small, so that the lip opening adjustment effect can be improved through a reasonable movement stroke. On the other hand, the movement stroke of the adjusting plate 20 can be avoided from being too large, so as to avoid the failure of the inclined surface fit between the two mold heads 200 due to excessive movement stroke.

[0115] like Figure 2 As shown, according to some embodiments of this application, the adjustment plate 20 is provided with a third limiting member 60, and the mounting plate 10 has a limiting hole 12 that cooperates with the third limiting member 60. When the adjustment plate 20 is at its maximum stroke, the third limiting member 60 is adapted to be inserted into the limiting hole 12.

[0116] Specifically, the adjustment plate 20 moves relative to the mounting plate 10 in the first direction, corresponding to a third limit position and a fourth limit position. The fourth limit position is located below the third limit position. When the adjustment plate 20 is in the fourth limit position, the third limiting member 60 can extend into the limiting hole 12.

[0117] In this way, the adjustment plate 20 can be limited to the fourth extreme position by the cooperation of the third limiting member 60 and the limiting hole 12, thereby improving the fixing stability of the adjustment plate 20, reducing the probability of the adjustment plate 20 and the spacing adjustment component 30 being completely detached from the mounting plate 10, further improving structural stability, and further reducing safety hazards.

[0118] Further integration Figure 1 and Figure 2 As shown, according to some embodiments of this application, the mounting plate 10 is provided with a fourth limiting member 70 at its end in the first direction. The fourth limiting member 70 protrudes from the mounting plate 10 and extends toward the side where the adjusting plate 20 is located. It is adapted to push and limit the adjusting plate 20 at its end when the adjusting plate 20 is at its maximum stroke.

[0119] In other words, when the adjustment plate 20 is in the fourth limit position, the fourth limiting member 70 can support the adjustment plate 20 and the spacing adjustment component 30 located on the adjustment plate 20 at the end of the mounting plate 10.

[0120] In this way, the fourth limiting member 70 can form a redundant limiting structure. During the adjustment process, if the third limiting member 60 fails or is not installed in the limiting hole 12, the fourth limiting member 70 can support the adjustment plate 20 from below, thereby reducing the probability of the adjustment plate 20 coming off the mounting plate 10 and further reducing safety hazards.

[0121] According to some embodiments of this application, a drive module (not shown in the figure) is provided on the mounting plate 10, which is used to drive the adjustment plate 20 to move relative to the mounting plate 10.

[0122] Specifically, the adjustment plate 20, the mounting plate 10, and the drive module define the first direction adjustment structure. The drive module can be constructed as a drive cylinder, which is fixedly mounted on the mounting plate 10. Alternatively, it can be mounted on the base of the die head 200 or the frame. The piston is connected to the die head 200. When compressed gas is introduced into the rodless chamber of the drive cylinder, the piston rod extends and pushes the die head 200 to drive the spacing adjustment component 30 to move synchronously with the die head 200. When compressed gas is introduced into the rod chamber of the drive cylinder, the piston rod retracts and pulls the die head 200 to move in the opposite direction, thereby realizing the adjustment of the lip opening.

[0123] In this way, the mold head adjustment device 100 can achieve automated adjustment in at least the first direction, which can further reduce the difficulty of adjustment and improve the efficiency of adjustment.

[0124] It is understood that the die head adjustment device 100 in this application embodiment provides a structural foundation for subsequent access to an automated control system. By further adding a motor-driven adjustment component 33 and setting a solenoid valve control drive module, automatic closed-loop control of the lip opening and the distance between the lip and the back roller can be further realized. The die head adjustment device 100 can be controlled by online detection of coating thickness, thereby realizing intelligent control of coating quality.

[0125] The cover plate (not shown in the figure) is installed on the outside of the spacing adjustment assembly and can be fastened to the die head 200 or the mounting plate 10 by screws. It can cover the connecting block 32, the reset piece 34, etc., reducing the probability of slurry, solvent or dust entering the spacing adjustment assembly 30 during the coating production process and causing contamination or jamming. The reset piece provides pre-tightening support. The cover plate can serve as a supplementary limiting surface for the limiting groove 13, further constraining the degree of freedom of movement of the connecting block 32 and ensuring the consistency of the movement direction.

[0126] like Figure 10As shown, this application provides a coating device 300, including: a die head adjustment device 100 as described in the above embodiment and a die head 200. There are at least two die heads 200, and a lip is defined between adjacent die heads 200. At least one of the two die heads 200 defining the same lip is provided with a die head adjustment device 100.

[0127] It should be noted that there can be two dies 200 for single-layer coating, or three or more dies 200 for double-layer or multi-layer coating.

[0128] Furthermore, based on the number of lips, one or more mold head adjustment devices 100 can be set. For example, if there are two mold heads 200, then at least one mold head adjustment device 100 can be set, and at most two mold head adjustment devices 100 can be set. If there are three mold heads 200, then at least two mold head adjustment devices 100 can be set, and at most three mold head adjustment devices 100 can be set.

[0129] Understandably, the die head adjustment device 100 can be integrated into the length end of the die head 200, and can be manufactured and pre-assembled independently as a standardized module, reducing the complexity of on-site installation and debugging. Both the old and new die heads 200 can be easily and quickly upgraded without large-scale modifications to the existing coating equipment 300. At the same time, the modular design also facilitates daily maintenance and fault repair.

[0130] According to the embodiments of this application, the coating equipment 300 adopts the above-mentioned die head adjustment device 100, which reduces the cost of the coating equipment 300, makes it easier to modify, and can improve production efficiency and coating quality.

[0131] In summary, this application proposes a die head adjustment device 100 that can adjust the lip opening and the distance between the lip and the back roller. Based on the existing die head 200, a spacing adjustment component 30 driven by an adjustment element 33 (micrometer) is added to both ends of the length of the die head 200. The adjustment plate 20 cooperates with the mounting plate 10, and through the "first direction adjustment structure" driven by the drive module, in conjunction with multiple limiting elements, high-precision adjustment of the lip opening and the distance between the lip and the back roller is achieved.

[0132] Among them, the adjusting component and the drive module serve as the power input parts, providing high-precision displacement drive in the second direction and coarse positioning drive in the first direction, respectively. The pitch of the adjusting component is designed with high precision, and one rotation corresponds to a determined linear displacement, thereby achieving micron-level adjustment accuracy.

[0133] The first guide member 11 and the second guide member 21 cooperate, and the adjustment groove 311 and the connecting block 32 cooperate to form two sets of motion guide parts, which can improve the position adjustment accuracy in the first direction and the second direction.

[0134] The reset component 34 always applies a preload force to ensure that the die head 200 fits tightly against the adjustment component, eliminating mechanical clearance and ensuring the accuracy and repeatability of the adjustment.

[0135] Multiple mold heads 200 serve as the adjustable structure, capable of generating high-precision displacement in the second and first directions to adjust the lip opening and the distance between the lip and the back roller.

[0136] The specific adjustment process of the die head adjustment device 100 in this embodiment is as follows: Step 1: Confirm that the mold head 200 is installed in place and the back roller is in the normal position. Check whether the adjustment parts, drive module, reset parts 34, etc. are intact, without looseness or damage. Connect the air source of the drive module and confirm that the air circuit of the drive module is connected correctly and without leakage.

[0137] Step 2: Adjust the plate 20 to move relative to the mounting plate 10 in the first direction, and visually inspect or use a feeler gauge to check whether the gap between the die head 200 and the back roller is uniform and whether the opening is appropriate.

[0138] Step 3: Based on the target coating thickness and slurry characteristics, rotate the adjustment component to the target scale value. After each rotation, let it stand for a few seconds until the overall stability is achieved. Then, use the pre-tightening force of the reset component 34 to automatically eliminate the adjustment gap and ensure adjustment accuracy.

[0139] Step 4: Start the coating equipment 300 for trial coating, use an online thickness gauge to check the coating thickness, and make fine adjustments to the adjustment parts according to the test results until the coating thickness reaches the target value.

[0140] Step 5: Record the final scale value of the adjustment component and the position parameters of the drive module, and incorporate the parameters into the process standard database for direct reference during the production of similar products in the future.

[0141] In summary, the die head adjustment device 100 of this application embodiment reduces the adjustment time from several hours to several minutes, which can improve adjustment efficiency, improve coating efficiency, and reduce production capacity waste. The adjustment accuracy is higher, which can improve coating quality. It eliminates the need for manual die flipping, which can reduce safety hazards, and provides a good structural foundation for subsequent automation and intelligent upgrades.

[0142] Furthermore, compared with existing automatic adjustment technologies, this solution has the following advantages: simple structure, low manufacturing cost, more flexible dual-degree-of-freedom adjustment, wide range of applicability, and the ability to eliminate mechanical backlash through the reset component 34, ensuring long-term accuracy and stability. Simulation verification shows that the reliability and safety of the structural design meet the requirements.

[0143] It should be noted that further structural modifications to the mold head adjustment device 100 of this application may include: (1) Electrification upgrade: Replace the adjustment components with an automatic structure driven by a stepper motor or servo motor, and use an encoder to achieve closed-loop control, further improving the level of automation and intelligence.

[0144] (2) Closed-loop control system: integrates online coating thickness detection sensor (such as X-ray thickness gauge or laser range sensor), feeds the detection signal back to the controller, and the controller automatically calculates the adjustment amount according to the coating thickness deviation and drives the die head adjustment device 100 to realize the fully automatic closed-loop adjustment of the lip opening.

[0145] (3) Multi-area independent adjustment: Multiple sets of independent spacing adjustment components 30 can be arranged along the length or width of the die head 200 to compensate for the uneven coating thickness caused by uneven pressure distribution in the cavity of the die head 200.

[0146] (4) Memory and self-learning: By combining process database and machine learning algorithm, the die head adjustment device 100 can memorize the adjustment parameters corresponding to different product specifications and optimize the adjustment strategy based on historical adjustment data, thereby shortening the debugging time when introducing new products.

[0147] Other configurations and operations of the coating apparatus 300 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
