Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a gasket adjustment device, adjustment method, coating equipment, and battery production system. Background Technology

[0002] In the production process of battery devices, electrode coating is required. For example, a slurry is applied to the surface of a substrate on a rotating coating roller through a coating die to form an active material layer of a specific thickness on the substrate surface.

[0003] The gasket of the coating die needs to be recessed inside the die during installation. The amount of recess has a certain impact on the coating quality. How to accurately adjust the amount of recess of the gasket to the required range is a research direction in battery technology. Summary of the Invention

[0005] In a first aspect, embodiments of this application provide a gasket adjustment device for adjusting the inward shrinkage of a gasket in a coating die head, comprising a mounting member, a calibration member, an adjusting member, and a driving assembly. The mounting member is configured to be detachably connected to a first die head of the coating die head. The calibration member is connected to the mounting member and has a first side surface configured to abut against the die lip of the first die head. The adjusting member is configured to be detachably mounted to the calibration member and, after being disconnected from the calibration member, can move along a first direction on the calibration member. The adjusting member has a third side surface, which, when in its initial position, is flush with the first side surface. The driving assembly is configured to drive the adjusting member from the initial position to an adjustment position along the first direction, such that the third side surface extends beyond the first side surface and is used to connect to and conform to the outlet of the gasket. The dimension by which the third side surface extends beyond the first side surface defines the inward shrinkage of the gasket. The first direction intersects the arrangement direction from the adjusting member to the calibration member.

The first side of the calibrating component abuts against the die lip of the first die head, aligning the adjusting component and the shim, and making the third side flush with one side of the shim. At this time, the distance between the shim and the die lip of the first die head is the shrinkage, which is equal to the size of the third side extending beyond the first side. Finally, the shim is installed and fixed. Compared with manual adjustment, the shim adjusting device provided in this application can more accurately adjust the shim to the required shrinkage.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, 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.

[0070] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "including," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0071] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0072] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0073] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0074] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0075] In this application, "multiple" means two or more (including two).

[0076] The embodiments of this application will now be described in detail.

[0077] In the production process of battery devices, electrode coating is one of the key steps, and its quality directly affects the electrochemical performance and safety of the battery.

[0078] The coating die is the core component for slurry coating. The gaskets installed inside it control the thickness and width of the coating film. To reduce the occurrence of scraping or damage to the back roller during coating, the gasket's inward shrinkage must be controlled during installation to ensure an appropriate distance between its end and the die lip. Simultaneously, the horizontal installation accuracy of the gasket must be guaranteed to maintain the consistency of the left-right width of the coating area.

[0079] Currently, the position of the gasket mainly relies on manual adjustment by operators, requiring repeated checks of its indentation distance using measuring equipment until it reaches the preset range. This process is highly dependent on operator experience, has limited adjustment efficiency, and is prone to fluctuations in gasket adjustment accuracy due to human factors, which in turn affects the stability of the coating dimensions.

[0080] Therefore, how to more accurately and effectively measure the shrinkage of the gasket is an important issue in battery manufacturing.

[0081] In view of this, this application provides a technical solution that solves the above-mentioned technical problem by providing a gasket adjustment device, which limits the amount of gasket retraction by the amount of the adjustment member extending out of the calibration member when adjusting the gasket retraction amount.

[0082] The following is in conjunction with the appendix Figures 1-10 The gasket adjustment device 100 provided in the embodiments of this application will be described.

[0083] Combined with appendix Figure 1-4As shown, this application embodiment provides a shim adjustment device 100 for adjusting the inward retraction of the shim 230 in the coating die 200. It includes a mounting member 10, a calibration member 20, an adjusting member 30, and a drive assembly 40. The mounting member 10 is configured to be detachably connected to the first die 210 of the coating die 200. The calibration member 20 is connected to the mounting member 10 and has a first side surface 21 configured to abut against the die lip 211 of the first die 210. The adjusting member 30 is configured to be detachably mounted to the calibration member 20, and after being disconnected from the calibration member 20, The adjusting member 30 is movable along the first direction X on the calibration member 20. The adjusting member 30 has a third side 31. When the adjusting member 30 is in the initial position, the third side 31 is flush with the first side 21. The driving assembly 40 is configured to drive the adjusting member 30 to move from the initial position to the adjusting position along the first direction X, so that the third side 31 extends out of the first side 21 and is used to connect and fit the outlet 2301 of the gasket 230. The size of the third side 31 extending out of the first side 21 defines the amount of inward retraction of the gasket 230. The first direction X intersects the alignment direction of the adjusting member 30 to the calibration member 20.

[0084] Mounting member 10 is used to detachably connect the first die head 210 of coating die head 200. In some embodiments, the first die head 210 can be the upper die head located above in actual production. There are various ways to detachably connect the mounting member 10 and the first die head 210, such as magnetic attraction, bolt connection, snap-fit, plug-in connection, etc. This embodiment will not list them one by one.

[0085] The calibration component 20 can be a plate-shaped component or a block-shaped component. The length of the calibration component 20 can be the same as the length of the upper die head. The width direction of the calibration component 20 is the same as the width direction of the upper die head. The calibration component 20 has a first side 21 and a second side 22 facing away from each other. The first direction X intersects the arrangement direction of the adjusting component 30 to the calibration component 20. The first direction X is also the arrangement direction of the second side 22 to the first side 21.

[0086] In some embodiments, the first side 21 and the second side 22 may be two sides of the calibration member 20 along the width direction.

[0087] The calibration component 20 is connected to the mounting component 10, and the first side 21 of the calibration component 20 is used to be flush with and abut against the die lip 211 of the first die head 210.

[0088] The mold lip 211 of the first mold head 210 refers to the end of the first mold head 210 from which the slurry is discharged. The mold lip 211 of the first mold head 210 (upper mold head) and the mold lip 211 of the second mold head 220 (lower mold head) together form the coating lip 240 of the coating mold head 200.

[0089] The adjusting member 30 is located on the surface of the calibrator 20 that is away from the mounting member 10. Specifically, the surface of the adjusting member 30 may be directly attached to the surface of the calibrator 20, or the adjusting member 30 and the calibrator 20 may be directly slidably connected through a structure such as a slide rail.

[0090] The adjusting member 30 is detachably connected to the calibrator 20 and can move on the surface of the calibrator 20 after being disconnected from the calibrator 20. Alternatively, the adjusting member 30 can be placed directly on the calibrator 20 and indirectly connected through an intermediate structure (such as the third connecting part 23 and the fourth connecting part 33 described below), and the intermediate structure can allow the adjusting member 30 and the calibrator 20 to be disconnected.

[0091] The adjusting member 30 has a third side 31 and a fourth side 32. When adjusting the inward shrinkage of the shim 230, the adjusting member 30 is first moved along the first direction X by the driving component 40 so that the third side 31 extends out of the first side 21 by the required inward shrinkage. Then the shim adjusting device 100 is installed on the first mold head 210 by the mounting member 10.

[0092] The dimension by which the third side 31 extends beyond the first side 21 is equal to the dimension by which the third side 31 extends into the first mold head 210 and is opposite to the surface of the first mold head 210.

[0093] When the third side surface 31 is an inclined plane, the dimension by which the third side surface 31 extends beyond the first side surface 21 refers to the maximum dimension by which the third side surface 31 protrudes beyond the first side surface 21.

[0094] It should be noted that during the process of installing the gasket adjustment device 100 onto the first mold head 210, the first mold head 210 and the second mold head 220 are in a certain position. Figure 2 In the unfolded state, the gasket 230 is not installed or fixed at this time.

[0095] The outlet 2301 of the gasket 230 refers to the side of the gasket 230 from which the slurry flows out.

[0096] After the shim adjustment device 100 is installed on the first mold head 210, the length direction (second direction Y) and width direction (first direction X) of the calibration member 20 are adjusted to be consistent with the length direction and width direction of the first mold head 210, respectively. At this time, the first side 21 of the calibration member 20 abuts against the mold lip 211 of the first mold head 210. Then, the size of the third side 31 of the adjustment member 30 extending beyond the first side 21 will limit the installation position of the shim 230.

[0097] Then, align the adjusting component 30 and the shim 230, making the third side 31 flush with one side of the shim 230. At this point, the distance between the shim 230 and the die lip 211 of the first die head 210 is equal to the distance between the third side 31 and the first side 21. This completes the determination of the inward shrinkage of the shim 230. Figure 4 and Figure 9 As shown, the indentation L is the distance between the two dashed lines.

[0098] Finally, the gasket 230 is installed and fixed to the first mold head 210 using bolts, screws and other fasteners to form... Figure 9 The state in.

[0099] Compared to manual adjustment, the above adjustment method can more accurately adjust the gasket 230 to the required inward shrinkage, thereby improving the stability of subsequent coating by the coating die 200.

[0100] In some examples, the mounting component 10 may optionally have a first connecting portion 11 at one end and a second connecting portion 12 at the other end. The first connecting portion 11 is used to detachably connect the first mold head 210, and the calibration component 20 is connected to the mounting component 10 through the second connecting portion 12.

[0101] The first connecting part 11 is a connecting structure located at one end of the mounting part 10 along the length direction. The first mounting part is used to detachably connect the first mold head 210. The detachable method can be bolt connection, snap-fit, plug-in connection, magnetic connection, etc.

[0102] Accordingly, the first die 210 of the coating die 200 needs to be improved, and the specific improvements are given below.

[0103] The second connecting part 12 is a connecting structure located at the other end of the mounting part 10 along the direction. The second connecting part 12 can be fixedly connected to the calibration part 20 or it can be detachably connected.

[0104] In this embodiment, the first connecting part 11 is used to detachably connect the first mold head 210, and the second connecting part 12 is used to connect the calibration part 20 and the mounting part 10, so as to facilitate the assembly of the mounting part 10 with the first mold head 210 and the calibration part 20 respectively.

[0105] In some examples, the first connecting part 11 may optionally include a first connecting hole 111, and the gasket adjusting device 100 may include a first locking member (not shown in the figure), which passes through the first connecting hole 111, and the first connecting hole 111 is connected to the first mold head 210 through the first locking member.

[0106] The first connecting part 11 can be designed as a second connecting ear located at one end of the mounting member 10. The thickness of the second connecting ear is less than the thickness of the rest of the mounting member 10, and the width of the second connecting ear is greater than the width of the rest of the mounting member 10. A first connecting hole 111 is provided on the second connecting ear. At this time, the first connecting part 11 includes the second connecting ear and the first connecting hole 111.

[0107] Of course, the first connecting hole 111 can also be directly opened on the first connecting part 11.

[0108] The first locking component can be a bolt, screw, connector, or other similar structure. Of course, other detachable locking components are not listed in this embodiment.

[0109] Accordingly, a fifth connecting hole (not shown in the figure) can be opened on the first mold head 210 to connect with the first locking member.

[0110] When assembling the mounting part 10 with the first mold head 210, first align the first connecting hole 111 and the fifth connecting hole so that they are connected. Then, the first locking part is inserted into the first connecting hole 111 and the fifth connecting hole, thereby completing the fixation of one end of the mounting part 10 on the first mold head 210. The structure is simple and easy to assemble and disassemble.

[0111] In some examples, the second connection 12 is optionally detachably connected to the calibration member 20, and / or the second connection 12 is hinged to the calibration member 20.

[0112] The above technical solutions may include three implementation methods. One method is that the second connecting part 12 and the calibration part 20 are detachably connected, and the two cannot rotate relative to each other after the connection.

[0113] In this manner, the second connecting part 12 and the calibration part 20 can be detachably connected by the aforementioned bolts, snap-fit, plug-in, magnetic attraction, and other methods.

[0114] Another option is that the second connecting part 12 is hinged to the calibration member 20 so that the two can rotate relative to each other, but the two are not detachable (this embodiment is not shown in the figure).

[0115] In this configuration, the second connecting part 12 and the calibration part 20 can be connected by a hinge structure such as a conventional hinge or a damping hinge. In particular, a damping hinge can keep the second connecting part 12 and the calibration part 20 stable after relative rotation.

[0116] Another type is where the second connecting part 12 and the calibration part are detachably connected, and simultaneously hinged so that they can rotate relative to each other (this embodiment is not shown in the figure).

[0117] In this manner, the second connecting part 12 and the calibration member 20 can be designed as a hinge structure with two rotating parts that can rotate relative to each other. One of the rotating parts is fixedly connected to the second connecting part 12, and the other rotating part is detachably connected to the calibration member 20 in the manner described above.

[0118] In this embodiment, the second connecting part 12 and the calibration part 20 are detachably connected, which facilitates the assembly and disassembly of the two.

[0119] The reason for hinged connection between the rotating part and the calibration part 20 is that the inclination of the bevel of the die lip 211 of the first die head 210 of different specifications may be different.

[0120] By hinged the second connecting part 12 to the calibration part 20, the angle between the calibration part 20 and the mounting part 10 can be adjusted to make the gasket adjustment device 100 match the coating die head 200 of different specifications, thereby improving the versatility of the gasket adjustment device 100.

[0121] In some examples, optionally, there are multiple mounting pieces 10, which are spaced apart along a second direction Y. Calibration pieces 20 are mounted on the multiple mounting pieces 10. The second direction Y intersects the first direction X and the arrangement direction of the adjustment pieces 30 to the calibration pieces 20.

[0122] The number of mounting parts 10 can be two or more, and multiple mounting parts 10 are arranged at intervals along the second direction Y.

[0123] When the gasket adjustment device 100 of this embodiment is installed on the first mold head 210, the second direction Y can also be the length direction of the first mold head 210. The second direction Y intersects with the first direction X. Specifically, the second direction Y can be perpendicular to the first direction X, and the first direction X is the width direction of the first mold head 210.

[0124] It is understood that the “length” and “width” mentioned in this embodiment are only used as illustrative textual identifiers to distinguish between two directions. The length in the attached figure can be greater than or equal to the width. Of course, the width can also be greater than the length (this implementation is not shown in the figure).

[0125] By designing multiple mounting parts 10, the support stability of the calibration part 20 can be improved, as well as the stability of the connection between the device and the coating die head 200.

[0126] In some examples, optionally, the calibration member 20 is provided with a third connecting part 23, and the adjusting member 30 is provided with a fourth connecting part 33. The connection between the third connecting part 23 and the fourth connecting part 33 is configured to switch between a connected state and an unlocked state. In the connected state, the adjusting member 30 is fixed to the calibration member 20, and in the unlocked state, the adjusting member 30 can move on the calibration member 20 along the first direction X.

[0127] The third connecting part 23 can be part of the calibration member 20 or a structure independent of the calibration member 20. Similarly, the fourth connecting part 33 can be part of the adjusting member 30 or a structure independent of the adjusting member 30.

[0128] The third connecting part 23 and the fourth connecting part 33 can be in a connected state or a disconnected state, thereby enabling the connection between the two to switch between a connected state and an unlocked state.

[0129] In practical use, the third connecting part 23 and the fourth connecting part 33 can be in the unlocked state first, so that the adjustment member 30 of this embodiment can be moved along the first direction X by the drive component 40, so that the third side 31 of the adjustment member 30 extends out of the first side 21 of the calibration member 20 by a size equal to the preset inward amount.

[0130] Then the third connecting part 23 and the fourth connecting part 33 are connected to maintain the size of the third side 31 extending out of the first side 21.

[0131] In some examples, the third connection part 23 may optionally include a first magnetic 231, and the fourth connection part 33 may include a second magnetic 332 that can magnetically engage with the first magnetic 231. At least one of the first magnetic 231 and the second magnetic 332 is an openable and closable electromagnet. In the connected state, the electromagnet is energized, and in the unlocked state, the electromagnet is de-energized.

[0132] In this embodiment, "magnetic attraction" refers to the structure's ability to actively attract ferromagnetic components, or it can refer to the structure being a ferromagnetic component that can be attracted by a magnetic component.

[0133] At least one of the first magnetic accelerator 231 and the second magnetic accelerator 332 is an openable and closable electromagnet, including at least three cases: one is that the first magnetic accelerator 231 is an openable and closable electromagnet, and the second magnetic accelerator 332 is a ferromagnetic component that can be magnetically attracted when energized.

[0134] Another type is where the second magnetic accelerator 332 is an openable and closable electromagnet, and the first magnetic accelerator 231 is a ferromagnetic component that can be magnetically attracted when energized.

[0135] Another type is where the first magnetic accelerator 231 and the second magnetic accelerator 332 are both openable and closable electromagnets, and they can magnetically attract each other when both are energized simultaneously.

[0136] Combined with appendix Figure 6 As shown in the figure, this embodiment is illustrated in the first manner, in which an electromagnet switch 24 can be configured on the calibration component 20 to open and close the first magnetic attractor 231.

[0137] This embodiment utilizes magnetic attraction to switch between the third connecting part 23 and the fourth connecting part 33 in the connected state and the unlocked state. The structure is simple and the switching is convenient.

[0138] Combined with appendix Figure 5 As shown, in some examples, the third connecting part 23 includes a plurality of second connecting holes (not shown in the figure) disposed on the calibrator 20 and arranged along the first direction X, and the fourth connecting part 33 includes a plurality of third connecting holes 331 disposed on the adjusting member 30 and arranged along the first direction X; the gasket adjusting device 100 also includes a second locking member (not shown in the figure). In the connected state, the second locking member passes through a set of interconnected second connecting holes and third connecting holes 331. In the unlocked state, the second locking member disengages from the set of interconnected second connecting holes and third connecting holes 331.

[0139] Figure 5 This is a bottom view of the calibration component 20 and the adjustment component 30 after they are connected. Figure 3 and 4 The adjustment component 30 and the calibration component 20 have the same viewing angle. The second connecting hole can be a blind hole or a through hole, and the third connecting hole 331 is a through hole.

[0140] Along the first direction X, the distance between two adjacent second connecting holes is equal to the distance between two adjacent third connecting holes 331. The distance between two adjacent second connecting holes can be from 1um to 50um, for example, it can be 1um, 5um, 10um, 20um, 30um, 40um, 50um, etc. This embodiment will not list them one by one.

[0141] Specifically, the spacing between the two second connecting holes can be determined based on the adjustment amount of the inward shrinkage of the gasket 230. For example, the adjustment range of the inward shrinkage is usually 50 to 150 μm, so the spacing between the two adjacent second connecting holes in this embodiment can be designed to be 10 μm.

[0142] The second locking member has the same or similar structure as the first locking member mentioned above, and will not be described in detail in this embodiment.

[0143] Before the adjusting member 30 is adjusted to extend into the first mold head 210, one of the third connecting holes 331 is opposite to one of the second connecting holes and is locked by the second locking member.

[0144] After the adjusting member 30 is adjusted to the preset inward amount by the driving component 40, the original third connecting hole 331 moves to the size of the inward amount, so that it can be opposite to the other second connecting holes, thereby continuing to lock through the second locking member.

[0145] The above structure designs the third connecting part 23 to include the second connecting hole and the fourth connecting part 33 to include the third connecting hole 331. By using the second locking member to connect the second connecting hole and the third connecting hole 331, the stability of the third connecting part 23 and the fourth connecting part 33 in the connected state can be improved.

[0146] Combined again with the appendix Figure 3 and attached Figure 4 As shown, in some examples, optionally, the third side 31 is provided with a fifth connecting portion 311 at both ends along the second direction Y. The distance between the two fifth connecting portions 311 is configured to be greater than or equal to the length of the gasket 230. The fifth connecting portion 311 is used to connect the gasket 230. The second direction Y intersects the first direction X and intersects the arrangement direction of the adjusting member 30 to the calibrating member 20.

[0147] The fifth connecting part 311 can be integrally formed with the third side 31 of this embodiment, or it can be integrally connected by other fixed connection methods.

[0148] Two fifth connecting parts 311 are used to connect the gasket 230. Accordingly, the gasket 230 in this embodiment needs to be provided with two sixth connecting parts 232. The two fifth connecting parts 311 and the two sixth connecting parts 232 are connected one-to-one.

[0149] The spacing between the two fifth connecting parts 311 is designed to be greater than or equal to the length of the gasket 230. This is because the outlet 2301 of the gasket 230 needs to fit with the third side 31 of this embodiment so that the inward shrinkage of the gasket 230 can be more intuitively represented as the size of the third side 31 extending out of the first side 21. If there is a fifth connecting part 311 between the third side 31 and the outlet 2301 of the gasket 230, then the inward shrinkage of the gasket 230 is equal to the size of the third side 31 extending out of the first side 21 minus the size of the fifth connecting part 311 along the first direction X.

[0150] Therefore, in this embodiment, two fifth connecting parts 311 with a spacing greater than or equal to the length of the gasket 230 are used to connect the gasket 230 and the adjusting member 30, while not affecting the tight alignment of one side of the gasket 230 with the third side 31.

[0151] In this embodiment, the fifth connecting part 311 and the sixth connecting part 232 can be connected in various ways, such as any of the detachable connection methods described above.

[0152] In some examples, the fifth connection portion 311 may optionally include a first connection ear 3111 and a fourth connection hole 3112 formed on the first connection ear 3111. The gasket adjustment device 100 may also include a third locking member 50, which passes through the fourth connection hole 3112. The fourth connection hole 3112 is connected to the gasket 230 through the third locking member 50.

[0153] The first connecting ear 3111 extends out of the third side 31 along the first direction X. The first connecting ear 3111 can be integrally formed with the adjusting member 30 in this embodiment during processing.

[0154] In order to match the first connecting ear 3111 and the fourth connecting hole 3112, the sixth connecting part 232 can be designed to include the third connecting ear 2321 and the sixth connecting hole 2322 opened on the third connecting ear 2321.

[0155] The third locking element 50 can be a bolt, screw, rivet, or other structure, as long as it can be inserted into the fourth connecting hole 3112 and the sixth connecting hole 2322 to achieve a detachable connection between the fifth connecting part 311 and the sixth connecting part 232.

[0156] The above structure utilizes the third locking member 50 through the fourth connecting hole 3112 and the gasket 230 to achieve the docking of the gasket 230 and the adjusting member 30, which results in a stable connection and easy disassembly and assembly.

[0157] Combined with appendix Figure 7 and 8 As shown, in some examples, the drive assembly 40 may optionally include a linear reciprocating motion member having a motion portion 41 that moves along a first direction X, the motion portion 41 being connected to the adjustment member 30.

[0158] Linear reciprocating motion components can be structures such as linear motors, pneumatic cylinders, hydraulic cylinders, and electric cylinders. Taking the linear motor in the figure as an example, it has advantages such as high adjustment accuracy, fast response speed, and low cost.

[0159] A linear motor generates a moving electromagnetic field through its stator (coils), which interacts with the magnetic field of its mover (permanent magnets), thereby directly generating electromagnetic thrust in a straight line, driving the load to reciprocate linearly, eliminating any intermediate mechanical conversion mechanism.

[0160] In addition to the stator and mover, the linear motor in this embodiment may include a motor circuit 42, a motion board 43, a guide rail slider 44, a magnetic grating sensor 45, an output platform, and a motion guide rail 46.

[0161] A motion guide rail 46 is mounted on a motion base plate 43, and a guide rail slider 44 is slidably connected to the motion guide rail 46. An output platform is mounted on the guide rail slider 44, and the output platform is the aforementioned motion part 41. A magnetic grating sensor 45 is connected to the output platform and is used to detect the precise position of the motor mover in real time and feed it back to the motor control system, thereby achieving nanometer-level positioning accuracy.

[0162] In some examples, the moving part 41 is optionally detachably connected to the adjusting part 30.

[0163] There are several ways to detachably connect the moving part 41 and the adjusting part 30. For example, they can be detachably connected directly by bolts, clips or other structures, or they can be detachably connected through an intermediate medium.

[0164] The moving part 41 is detachably connected to the adjusting part 30. After the adjusting part 30 is moved, the adjusting part 30 is connected to the calibration part 20. Then the connection between the moving part 41 and the adjusting part 30 can be released. When installing the shim adjusting device 100, it is only necessary to install the mounting part 10, the calibration part 20 and the adjusting part 30 on the coating die head 200, which facilitates the installation and removal of the device.

[0165] In some examples, the pad adjusting device 100 may optionally include a transition assembly 60, which is detachably connected to at least one of the moving part 41 and the adjusting member 30, which are detachably connected via the transition assembly 60.

[0166] The adapter 60 can be detachably connected to the moving part 41, or detachably connected to the adjusting member 30, or the adapter 60 can be detachably connected to both the moving part 41 and the adjusting member 30.

[0167] The detachable connection method can be any of the above-mentioned methods, which will not be elaborated in this embodiment.

[0168] The adapter 60 facilitates the detachable connection between the moving part 41 and the adjusting part 30. After the driving component 40 moves the adjusting part 30, the connection between the driving component 40 and the adjusting part 30 can be removed. In this way, after the shim adjusting device 100 is installed on the coating die head 200, not only is the overall weight of the shim adjusting device 100 reduced, but the driving component 40 will not exert any stress on the adjusting part 30, the calibration part 20 and the mounting part 10, thereby improving the stability of the adjusting part 30, the calibration part 20 and the mounting part 10 on the coating die head 200.

[0169] In some examples, the adapter 60 may optionally include a connector 61, a fourth locking member 62, and a fifth locking member 63. One end of the connector 61 is provided with a first support wall 611, and the other end of the connector 61 is provided with a second support wall 612. The fourth locking member 62 passes through the first support wall 611 and is detachably connected to the adjusting member 30. The fifth locking member 63 passes through the second support wall 612 and is detachably connected to the moving part 41.

[0170] The first support wall 611 can be located at one end of the opposite ends of the connector 61, and the second support wall 612 can be located at the other end of the opposite ends of the connector 61, so that the connector 61 forms an approximately U-shaped connection structure.

[0171] Of course, the shape of the connector 61 is not limited to this. For example, it can also be plate-shaped, rod-shaped, etc. This embodiment will not list them in detail.

[0172] Both the first support wall 611 and the second support wall 612 may be provided with connecting holes. Correspondingly, the adjusting member 30 is provided with a hole that corresponds to and engages with the connecting hole on the first support wall 611, and the moving part 41 is provided with a hole that corresponds to and engages with the connecting hole on the second support wall 612.

[0173] The fourth locking member 62 and the fifth locking member 63 can be bolts. The fourth locking member 62 passes through the holes in the first support wall 611 and the adjusting member 30 to achieve their connection. The fifth locking member 63 passes through the holes in the second support wall 612 and the moving part 41 to achieve their connection. The structure is simple and easy to assemble and disassemble.

[0174] Combined again with the appendix Figure 1-4 As shown, in some examples, the gasket adjustment device 100 may optionally include a detection component 70, which is mounted on the adjustment member 30 and used to detect the amount of retraction of the gasket 230.

[0175] The detection component 70 can be a vision detection component 70, a photoelectric sensor array detection component 70, or a mechanical detection component 70 (such as a ruler).

[0176] The inner shrinkage of the gasket 230 is detected by the detection component 70, so as to easily determine whether the inner shrinkage of the gasket 230 meets the requirements.

[0177] In some examples, the detection component 70 may optionally include an image acquisition mechanism 71 and a data processing mechanism (not shown in the figure). The image acquisition mechanism 71 is mounted on the adjustment member 30 in a manner movable along the second direction Y and is used to acquire image information of the shim 230 and the first mold head 210. The data processing mechanism is communicatively connected to the image acquisition mechanism 71 and is used to determine the inward shrinkage of the shim 230. The second direction Y intersects the arrangement direction from the second side 22 to the first side 21.

[0178] The image acquisition mechanism 71 can be a CCD camera, CMOS camera, or other structures, and the data processing mechanism (not shown in the figure) can include a processor or a control circuit such as a PLC.

[0179] The image acquisition mechanism 71 is used to acquire images of the gasket 230 and the inner surface of the first die head 210 for material discharge.

[0180] The image acquisition mechanism 71 can be slidably connected to the adjusting member 30, so a slide 34 needs to be configured between the two. For example, the slide 34 is configured on the adjusting member 30, and the image acquisition mechanism 71 is mounted on the adjusting member 30 by a slider 35 that can move along the slide 34.

[0181] By analyzing the image, the data processing mechanism can not only obtain the inward shrinkage of the gasket 230, but also the distances between the two ends of the gasket 230 along the length direction (the second direction Y in the figure) and the edge of the first mold head 210, as well as the burr condition of the gasket 230 and the wear condition of the mold lip 211 of the first mold head 210.

[0182] The data processing unit can communicate with the control system of the coating equipment 1000 (wireless signal or wired connection) so that the aforementioned shrinkage, the distance between the two ends of the gasket 230 and the edge of the first die head 210, the burr condition and the wear condition can all be displayed on the control panel of the coating equipment 1000, thereby prompting the staff to handle the situation.

[0183] As can be seen from the above description, this embodiment uses an image acquisition mechanism 71 that can move along the second direction Y to acquire multiple image information of the side where the gasket 230 is in contact with the third side 31, which can more accurately determine whether the inward shrinkage of the gasket 230 meets the requirements.

[0184] Based on the aforementioned gasket adjustment device 100, such as Figure 10 As shown, this application embodiment provides a coating device 1000, including a coating die 200 and the aforementioned gasket adjustment device 100. The coating die 200 includes a first die 210, a second die 220, and a gasket 230. The die lip 211 of the first die 210 and the die lip 211 of the second die 220 form a coating lip 240 for the slurry. The gasket 230 is installed between the first die 210 and the second die 220.

[0185] In some embodiments, the first die head 210 may be the upper die head of the coating die head 200, and the second die head 220 may be the lower die head of the coating die head 200, or vice versa. The gasket 230 is located between the first die head 210 and the second die head 220.

[0186] The structural improvements made to the upper mold head for cooperation with the shim adjustment device 100 have been described above in this embodiment, and will not be repeated here.

[0187] The coating die 200 is provided with a slurry inlet 250, and the coating equipment 1000 also includes a coating roller 300 for driving the electrode 2000 to rotate. The lip of the coating die 200 coats the electrode 2000 with slurry on the coating roller 300.

[0188] Based on the coating equipment 1000 described above, this application embodiment provides a battery production system including the coating equipment 1000. Furthermore, the battery production system may also include slurry preparation and supply equipment, electrode drying equipment, etc., which will not be described in detail in this embodiment.

[0189] Based on the gasket adjustment device 100 described above, this application embodiment provides a gasket adjustment method, which includes the following steps:

[0190] Install the gasket adjustment device 100 on the first die 210 of the coating die 200;

[0191] The first side 21 of the calibration member 20 of the shim adjustment device 100 abuts against the mold lip 211 of the first mold head 210, and the third side 31 of the adjustment member 30 on the calibration member 20 is flush with the first side 21.

[0192] Adjust the position of the calibration component 20 along the first direction X so that the third side 31 is in contact with the shim 230 on the first mold head 210. At this time, the size of the third side 31 extending out of the first side 21 is the inward shrinkage of the shim 230.

[0193] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0194] Combined with appendix Figure 1-9As shown, this application embodiment provides a shim adjustment device 100 for adjusting the inward retraction of the shim 230 in the coating die 200. It includes a mounting member 10, a calibration member 20, an adjusting member 30, and a drive assembly 40. The mounting member 10 is configured to be detachably connected to the first die 210 of the coating die 200. The calibration member 20 is connected to the mounting member 10 and has a first side surface 21 configured to abut against the die lip 211 of the first die 210. The adjusting member 30 is configured to be detachably mounted to the calibration member 20, and after being disconnected from the calibration member 20, The adjusting member 30 is movable along the first direction X on the calibration member 20. The adjusting member 30 has a third side surface 31, which is flush with the first side surface 21 when the adjusting member 30 is in its initial position. The driving assembly 40 is configured to drive the adjusting member 30 from its initial position to an adjusted position along the first direction X, such that the third side surface 31 extends beyond the first side surface 21 and is used to connect to and fit the outlet 2301 of the gasket 230. The size of the third side surface 31 extending beyond the first side surface 21 defines the inward retraction of the gasket 230. The first direction X intersects the alignment direction of the adjusting member 30 to the calibration member 20. One end of the mounting member 10 has a first connecting portion 11, and the other end has a second connecting portion 12.

In the connected state, the adjusting member 30 is fixed to the calibration member 20. In the unlocked state, the adjusting member 30 can move along the first direction X on the calibration member 20. The third connecting part 23 includes a first magnetic 231, and the fourth connecting part 33 includes a second magnetic 332 that can magnetically cooperate with the first magnetic 231. At least one of the first magnetic 231 and the second magnetic 332 is an openable and closable electromagnet.

In the connected state, the second locking member passes through a set of interconnected second connecting holes and third connecting holes 331. In the unlocked state, the second locking member disengages from the set of interconnected second connecting holes and third connecting holes 331. The third side surface 31 has a fifth connecting part 311 at both ends along the second direction Y. The distance between the two fifth connecting parts 311 is configured to be greater than or equal to the length of the shim 230. The fifth connecting part 311 is used to connect the shim 230. The second direction Y intersects the first direction X and intersects the arrangement direction from the adjusting member 30 to the calibration member 20. The fifth connecting part 311 includes a first connecting ear 3111 and a fourth connecting hole 3112 formed on the first connecting ear 3111. The gasket adjusting device 100 also includes a third locking member 50, which passes through the fourth connecting hole 3112. The fourth connecting hole 3112 is connected to the gasket 230 through the third locking member 50. The drive assembly 40 includes a linear reciprocating motion member, which has a motion part 41 that moves along a first direction X. The motion part 41 is connected to the adjusting member 30. The motion part 41 is detachably connected to the adjusting member 30.

The motion part 41 and the adjusting member 30 are detachably connected through the transition assembly 60. The adapter assembly 60 includes a connector 61, a fourth locking member 62, and a fifth locking member 63. One end of the connector 61 is provided with a first support wall 611, and the other end of the connector 61 is provided with a second support wall 612. The fourth locking member 62 passes through the first support wall 611 and is detachably connected to the adjusting member 30.
