Description

Technical Field

[0001] This utility model relates to an adsorption plate and adsorption device, belonging to the field of lithium-ion battery technology. Background Technology

[0002] Lithium-ion batteries require adhesive application during processing. However, traditional winding equipment, in situations requiring negative pressure adsorption and adhesive application (e.g., electrode exchange tape application; positive electrode cutting and application; termination tape application), suffers from inconsistent adsorption plate hole positions due to variations in product dimensions. Furthermore, the width of the cathode electrode affects the compatibility of the adhesive application device across different machine types. Since the transparent tape must first adhere to the adhesive application plate, and the hole distribution is fixed, the narrowing width results in only partial adhesion between the tape and the plate, leaving the vacuum holes exposed. This can cause abnormal vacuum adsorption, leading to tape detachment from the plate before application, resulting in adhesive loss and vacuum leakage. This triggers numerous vacuum alarms, increasing equipment downtime and impacting production cycle time. Furthermore, adhesive loss during application increases the risk of battery short circuits and negatively affects subsequent battery cycle characteristics and safety performance. Traditional methods of applying transparent Teflon to the surface of the pressure plate are prone to damage and insufficient adhesion, causing the tubes to fall off and resulting in secondary vacuum alarms.

[0003] Existing adsorption plates, such as CN113921974B - a tape adsorption mechanism and adhesive applicator, include an adsorption plate with a plurality of adsorption holes arranged in an array; a piston seat connecting the adsorption plate and other structures, which adsorb tape by generating negative pressure through the piston. However, its structure is not suitable for adsorbing tapes of various sizes, affecting the practicality of the adsorption plate. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an adsorption plate and adsorption device. The porous partition with different through hole array positions and numbers can be flexibly replaced according to the actual tape size, so as to facilitate the adsorption of tapes of different sizes and ensure the practicality of this application.

[0005] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution: In a first aspect, this utility model provides an adsorption plate, including a porous adsorption plate body, a porous auxiliary plate, and several porous partitions; wherein the position and number of through holes in each of the porous partitions are different. The porous auxiliary plate is detachably installed on the adsorption surface of the porous adsorption plate body. A porous partition is sandwiched between the porous auxiliary plate and the porous adsorption plate body. The through-hole array of the porous partition connects the through-holes of the porous auxiliary plate and the through-holes of the porous adsorption plate body on both sides. The non-through-hole array area of ​​the porous partition separates the through-holes of the porous auxiliary plate and the through-holes of the porous adsorption plate body on both sides.

[0006] The above technical solution allows for the removal of porous auxiliary plates from the porous adsorption plate body when different sizes of tape need to be adsorbed. The porous partitions can be removed, and porous partitions with different through-hole array positions and numbers can be replaced according to the actual size of the tape. The porous partitions are then reattached to the adsorption surface of the porous adsorption plate body using the porous auxiliary plate. The array position and number of through holes in the porous partitions match the size of the tape, allowing some through holes on the porous adsorption plate body to connect with some through holes in the porous partitions and the porous auxiliary plate. This adjusts the number and position of through holes in the porous auxiliary plate that actually adsorb the tape, achieving tape adsorption. The remaining through holes on the porous adsorption plate body are blocked by the porous partitions and do not perform adsorption. Different porous partitions can be flexibly replaced according to actual work needs, thus achieving the adsorption of tapes of different sizes and ensuring the practicality of this application.

[0007] Optionally, the number of through holes in the porous adsorption plate body is the same as the number of through holes in the porous auxiliary plate, and the through holes in the porous adsorption plate body are respectively paired with the through holes in the porous auxiliary plate.

[0008] The above technical solution aligns the through holes of the porous adsorption plate body with the through holes of the porous auxiliary plate, which facilitates the processing of the porous adsorption plate body and the porous auxiliary plate, and also makes it easy to visually observe the position of the through hole array of the porous partition.

[0009] Optionally, the array of through holes in the porous partition is located in the middle of the porous partition.

[0010] The above technical solution controls the position of the through-hole array of the porous partition, thereby controlling the through-holes of the porous auxiliary plate that actually participates in the adsorption work to the middle position, leaving adjustment space to facilitate the adsorption work of the tape.

[0011] Secondly, this utility model provides an adsorption device, which, based on the adsorption plate described in the first aspect, further includes a vacuum mechanism, wherein the through holes of the porous adsorption plate body are all connected to the suction port of the vacuum mechanism.

[0012] In the above technical solution, when it is necessary to adsorb the tape, the vacuum structure starts to work, thereby extracting the air from the through holes that connect the porous adsorption plate body, the porous auxiliary plate, and the porous partition, so as to adsorb the tape on one side of the porous auxiliary plate.

[0013] Optionally, the porous adsorption plate body has a cavity inside, and the through holes of the porous adsorption plate body are all connected to the cavity, which is connected to the suction port of the vacuum mechanism.

[0014] The above technical solution connects the suction port of the vacuum mechanism with the through holes of the porous adsorption plate body through a cavity, which facilitates uniform vacuuming of each through hole of the porous adsorption plate body and ensures the adsorption stability of this application.

[0015] Optionally, it also includes a back plate detachably connected to the porous adsorption plate body. When the back plate is assembled with the porous adsorption plate body, it is used to form a cavity. The through holes of the porous adsorption plate body are all connected to the cavity, and the cavity is connected to the suction port of the vacuum mechanism.

[0016] The above technical solution obtains a cavity by assembling the back plate and the porous adsorption plate body, and performs vacuuming work through a vacuum mechanism and the cavity to separate the upper and lower sides of the cavity, thereby facilitating the processing of the porous adsorption plate body and the back plate. It eliminates the need to hollow out the cavity inside the porous adsorption plate body, thus ensuring the practicality of this application.

[0017] Optionally, the suction port of the vacuum mechanism is connected to the cavity via a speed regulating valve.

[0018] The above technical solution adjusts the working efficiency of the vacuum mechanism by means of a speed regulating valve to meet actual working requirements, thus ensuring the practicality of this application.

[0019] Optionally, a sealing ring is placed on the inner wall of the back plate.

[0020] The above technical solution seals the back plate and the porous adsorption plate body with a sealing ring, ensuring the sealing effect of the cavity and thus ensuring the stability of the vacuuming operation.

[0021] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: The adsorption plate can be flexibly replaced with porous partitions with different through-hole array positions and numbers according to the actual tape size, thereby facilitating the adsorption of tapes of different sizes and ensuring the practicality of this application.

[0024] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0027] like Figures 1-2As shown, this utility model provides an adsorption plate, including a porous adsorption plate body 1, a porous auxiliary plate 2, and several porous partitions 3; wherein the position and number of through holes in each of the porous partitions 3 are different; the porous auxiliary plate 2 is detachably installed on the adsorption surface of the porous adsorption plate body 1, and a porous partition 3 is sandwiched between the porous auxiliary plate 2 and the porous adsorption plate body 1; the through hole array of the porous partition 3 connects the through holes of the porous auxiliary plate 2 and the through holes of the porous adsorption plate body 1 on both sides, and the non-through hole array area of ​​the porous partition 3 separates the through holes of the porous auxiliary plate 2 and the through holes of the porous adsorption plate body 1 on both sides.

[0028] Specifically, when it is necessary to adsorb tapes of different sizes, the porous auxiliary plate 2 can be removed from the porous adsorption plate body 1, and the porous partition plate 3 can be removed. Depending on the actual size of the tape, a porous partition plate 3 with different through-hole array positions and numbers can be replaced. The porous partition plate 3 can then be reattached to the adsorption surface of the porous adsorption plate body 1 using the porous auxiliary plate 2. The through-hole array positions and numbers of the porous partition plate 3 match the size of the tape, allowing some of the through-holes on the porous adsorption plate body 1 to pass through the through-hole array of the porous partition plate 3. The porous auxiliary plate 2 is connected to some of the through holes, thereby adjusting the number and position of the through holes of the porous auxiliary plate 2 that actually participate in the adsorption of the tape, so as to achieve the adsorption of the tape. The remaining through holes on the porous adsorption plate body 1 are blocked by the non-through hole array area of ​​the porous partition 3, so that the through holes on the side of the non-through hole array area of ​​the porous partition 3 in the porous auxiliary plate 2 do not perform adsorption work. According to the actual work requirements, the porous partition 3 with different through hole array positions and numbers can be flexibly replaced, thereby achieving the adsorption of tape of different sizes, ensuring the practicality of this application.

[0029] This application allows for flexible replacement of porous partitions 3 with different through-hole array positions and quantities according to the actual tape size, thereby facilitating the adsorption of tapes of different sizes. Furthermore, the porous partitions 3 block some through-holes of the porous adsorption plate body 1 that are not involved in the operation, preventing vacuum leakage in the vacuum mechanism and ensuring the practicality and safety of this application.

[0030] In this embodiment, the number of through holes in the porous adsorption plate body 1 is the same as the number of through holes in the porous auxiliary plate 2, and the through holes in the porous adsorption plate body 1 are opposite to the through holes in the porous auxiliary plate 2 in pairs.

[0031] Specifically, the through holes of the porous adsorption plate body 1 and the through holes of the porous auxiliary plate 2 are aligned to facilitate the processing of the porous adsorption plate body 1 and the porous auxiliary plate 2, and at the same time to facilitate the intuitive observation of the through hole array position of the porous partition 3, ensuring the convenience of use of this application; optionally, the through holes on the porous adsorption plate body 1, the porous auxiliary plate 2 and the porous partition 3 are evenly distributed to ensure the stability when adsorbing tape.

[0032] In some possible embodiments, the porous adsorption plate body 1 has a groove 8 on its adsorption surface that is adapted to the porous auxiliary plate 2, which facilitates the determination of the relative position of the porous adsorption plate body 1 and the porous auxiliary plate 2, and at the same time ensures the stability of the porous auxiliary plate 2 during installation.

[0033] Specifically, the groove 8 is adapted to both the porous adsorption plate body 1 and the porous partition 3. When it is necessary to adsorb tape of different sizes, the porous auxiliary plate 2 can be removed and the porous partition 3 can be taken off. According to the actual size of the tape, the porous partition 3 with different through-hole array positions and numbers can be flexibly replaced. The new porous partition 3 is fixed inside the groove 8 by the porous auxiliary plate 2. The porous partition 3, the porous auxiliary plate 2 and the groove 8 are pressed together. The position and number of through-hole arrays on the porous partition 3 match the size of the tape, thereby adjusting the number and position of through-holes of the porous auxiliary plate 2 that actually participate in adsorbing the tape, so as to achieve the adsorption of tape of different sizes. The remaining through-holes of the porous auxiliary plate 2 are blocked by the porous partition 3 and do not perform adsorption work, so as to avoid vacuum leakage in the vacuum mechanism.

[0034] In this embodiment, the through-hole array in the porous partition 3 is located in the middle of the porous partition 3; by controlling the position of the through-hole array in the porous partition 3, the through-holes of the porous auxiliary plate 2 that actually participates in the adsorption work are controlled in the middle position, leaving room for adjustment to facilitate the adsorption work of the tape. Example 2:

[0035] like Figures 1-2 As shown, this utility model provides an adsorption device based on the adsorption plate described in Embodiment 1, and further includes a vacuum mechanism. The through holes of the porous adsorption plate body 1 are all connected to the suction port of the vacuum mechanism.

[0036] Specifically, when it is necessary to adsorb the tape, the vacuum structure starts to work, thereby extracting the air from the through holes that connect the porous adsorption plate body 1, the porous auxiliary plate 2, and the porous partition plate 3, so as to adsorb the tape on one side of the porous auxiliary plate 2; optionally, the vacuum mechanism is a vacuum pump or similar device used for vacuuming.

[0037] In some possible embodiments, a cavity 4 is provided inside the porous adsorption plate body 1, and all the through holes of the porous adsorption plate body 1 are connected to the cavity 4. The cavity 4 is connected to the suction port of the vacuum mechanism. By connecting the suction port of the vacuum mechanism with the through holes of the porous adsorption plate body 1 through the cavity 4, it is convenient to perform uniform vacuuming on each through hole of the porous adsorption plate body 1, thus ensuring the adsorption stability of this application.

[0038] In this embodiment, a back plate 5 is also included that is detachably connected to the porous adsorption plate body 1. When the back plate 5 is assembled with the porous adsorption plate body 1, it is used to form a cavity 4. All the through holes of the porous adsorption plate body 1 are connected to the cavity 4, and the cavity 4 is connected to the suction port of the vacuum mechanism.

[0039] Specifically, the cavity 4 is obtained by assembling the back plate 5 with the porous adsorption plate body 1, and the cavity 4 is evacuated by a vacuum mechanism to separate the upper and lower sides of the cavity 4. This facilitates the processing of the porous adsorption plate body 1 and the back plate 5, eliminating the need to remove the cavity 4 from the inside of the porous adsorption plate body 1, thus ensuring the practicality of this application.

[0040] In this embodiment, the suction port of the vacuum mechanism is connected to the cavity 4 through a speed regulating valve 6; the working efficiency of the vacuum mechanism is adjusted by the speed regulating valve 6 to meet the actual working requirements, thus ensuring the practicality of this application; optionally, there are multiple speed regulating valves 6.

[0041] In this embodiment, a sealing ring 7 is placed on the inner wall of the back plate 5; the above technical solution seals the back plate 5 and the porous adsorption plate body 1 with the sealing ring 7, ensuring the sealing effect of the cavity 4, thereby ensuring the stability of the vacuuming operation.

[0042] Optionally, the through holes in the groove 8 are distributed in a 2mm-2.5mm grid pattern. The porous adsorption plate body 1 is made of SUS304 stainless steel, and the back plate 5 is made of AL6061 aluminum alloy with a natural anodized finish. The porous partition 3 is attached to the inner wall of the groove 8, and corresponding holes are punched according to the required tape size. Optionally, the porous partition 3 is made of transparent Teflon. Finally, the porous auxiliary plate 2 is installed in the groove 8. The porous auxiliary plate 2 is made of PU material. The through holes of the perforated auxiliary plate 2 are also distributed in a 2mm-2.5mm grid pattern, corresponding and penetrating each other with the through holes of the porous adsorption plate body 1; different transparent Teflon can be replaced according to different models, thereby flexibly adjusting the required pore positions; at the same time, in the traditional way, the transparent Teflon is easily damaged and falls off due to insufficient adhesion when attached to the surface of the porous auxiliary plate 2, causing secondary vacuum alarm problems. However, this application avoids the above problems by limiting the porous partition plate 3 through the groove 8 and the porous auxiliary plate 2.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
