Description

Technical Field

[0001] This utility model relates to the field of electrode cleaning technology, and in particular to an adsorption device and cleaning equipment. Background Technology

[0002] In one stage of battery production, the areas of the electrodes to be cleaned need to be cleaned using a laser cleaning device. During cleaning, the electrodes are placed on a fixed platform to hold them in place. Then, a laser beam emitted by the laser cleaning device ablates, vaporizes, and peels off the surface of the electrodes, thus cleaning the surface.

[0003] In related technologies, a fixing platform uses negative pressure to adsorb and fix the electrodes on it. The adsorption force of the fixing platform on the areas of the electrode to be cleaned and the areas not to be cleaned is basically the same, and the fixing platform cannot generate different adsorption forces according to different areas of the electrode. When the electrode is placed on the fixing platform, the platform needs to generate a large adsorption force to adsorb and fix the electrode. However, during the cleaning process, the structure of the area to be cleaned on the electrode is thinner than that of the uncleaned area. As a result, after the area to be cleaned is cleaned, its surface will have pore marks caused by the adsorption of the fixing platform, which affects the production yield of the electrode. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an adsorption device and cleaning equipment capable of generating corresponding adsorption forces for different areas of the electrode.

[0005] In a first aspect, embodiments of the present invention provide an adsorption device for adsorbing electrode sheets to be cleaned, the adsorption device comprising:

[0006] The adsorption platform includes a first adsorption plate and a second adsorption plate. The first adsorption plate defines a plurality of first adsorption holes, and the second adsorption plate defines a plurality of second adsorption holes. The plurality of first adsorption holes are used to adsorb the non-cleaned area of ​​the electrode sheet, and the plurality of second adsorption holes are used to adsorb the cleaned area of ​​the electrode sheet.

[0007] The first negative pressure component is connected to the first adsorption plate and communicates with a plurality of first adsorption holes. The first negative pressure component is used to generate a first adsorption force in the first adsorption holes.

[0008] The second negative pressure component is connected to the second adsorption plate and communicates with a number of second adsorption holes. The second negative pressure component is used to generate a second adsorption force in the second adsorption holes.

[0009] The adsorption device according to the embodiments of the present invention has at least the following beneficial effects:

[0010] By setting up a number of first adsorption holes corresponding to the uncleaned areas of the electrode and a number of second adsorption holes corresponding to the areas to be cleaned of the electrode, and by setting up a first negative pressure component corresponding to the first adsorption plate and a second negative pressure component corresponding to the second adsorption plate, the adsorption platform can use different airflow paths to adsorb and fix the uncleaned areas and the areas to be cleaned respectively. When the adsorption platform adsorbs and fixes the electrode, the first negative pressure component can generate a first adsorption force in the number of first adsorption holes, and the second negative pressure component can generate a second adsorption force in the number of second adsorption holes. This allows for the generation of corresponding adsorption forces in the uncleaned areas and the areas to be cleaned of the electrode, so that the adsorption forces of the first adsorption holes and the second adsorption holes can be controlled and adjusted separately. This avoids the situation where the adsorption forces of the first adsorption holes and the second adsorption holes are basically the same, resulting in excessive adsorption force of the second adsorption holes, which may cause hole marks, or insufficient adsorption force, which may result in incomplete cleaning and surface residue. This improves the appearance yield and production yield of the electrode.

[0012] The second negative pressure component includes a second pipe and a second pressure regulating valve. The two ends of the second pipe are connected to the second adsorption plate and the second pressure regulating valve, respectively, and the second pipe is connected to a number of second adsorption holes. The second pressure regulating valve is used to adjust the second adsorption force of the second adsorption holes.

[0013] According to the adsorption device of this utility model embodiment, a first adsorption plate defines a first adsorption area, and a plurality of first adsorption holes are located within the first adsorption area. The first adsorption area is used for the non-cleaning area of ​​the corresponding adsorption electrode. A second adsorption plate defines a second adsorption area, and a plurality of second adsorption holes are located within the second adsorption area. The second adsorption area is used for the cleaning area of ​​the corresponding adsorption electrode.

[0014] A notch is defined on one side of the first adsorption region, and the second adsorption region is set within the notch.

[0015] According to the adsorption device of this utility model embodiment, the first adsorption plate and the second adsorption plate are detachably connected.

[0016] According to the adsorption device of this utility model embodiment, a groove is defined on the outer peripheral sidewall of the first adsorption plate, and the groove extends through the first adsorption plate along the thickness direction of the first adsorption plate, and the second adsorption plate is embedded in the groove.

[0017] According to the adsorption device of this utility model embodiment, the inner sidewall of the groove is provided with a first positioning structure, and the peripheral sidewall of the second adsorption plate is provided with a second positioning structure. The first positioning structure and the second positioning structure cooperate to make the upper surface of the first adsorption plate and the upper surface of the second adsorption plate flush.

[0018] According to the adsorption device of the present invention, one of the first positioning structure and the second positioning structure is a slot, and the other of the first positioning structure and the second positioning structure is a protrusion, which is inserted into the slot.

[0019] According to the adsorption device of this utility model embodiment, the thickness of the second adsorption plate is greater than or equal to 10 mm.

[0020] According to the adsorption device of this utility model embodiment, the thickness of the first adsorption plate is less than the thickness of the second adsorption plate.

They 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.

[0035] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] In related technologies, a fixed platform simultaneously adsorbs and fixes the areas to be cleaned and the uncleaned areas of the electrode. During the cleaning process of the areas to be cleaned, as the surface layer is gradually removed, the thickness of the areas to be cleaned gradually decreases, making the thickness of the areas to be cleaned smaller than that of the uncleaned areas. However, the adsorption force of the fixed platform on the areas to be cleaned and the uncleaned areas of the electrode is basically the same, and the fixed platform cannot generate corresponding adsorption forces for different areas of the electrode. When the adsorption force generated by the fixed platform to just barely fix the uncleaned areas of the electrode is large, the surface of the areas to be cleaned is left with the hole imprints caused by the adsorption of the fixed platform after cleaning. When the adsorption force generated by the fixed platform to just barely fix the areas to be cleaned is small, the areas to be cleaned cannot be stably fixed on the fixed platform, resulting in incomplete cleaning and surface residue in the areas to be cleaned, affecting the production yield of the electrode.

[0039] In view of this, the present invention provides an adsorption device 100, which is used to adsorb the electrode sheet to be cleaned. The adsorption device 100 can generate corresponding adsorption forces for different areas of the electrode sheet.

[0040] Please see Figure 1 and Figure 2 The adsorption device 100 includes an adsorption platform 10, a first negative pressure component 20, and a second negative pressure component 30.

[0041] The adsorption platform 10 includes a first adsorption plate 11 and a second adsorption plate 12. The first adsorption plate 11 defines a plurality of first adsorption holes 1101, and the second adsorption plate 12 defines a plurality of second adsorption holes 1201. The plurality of first adsorption holes 1101 are used to adsorb the non-cleaned area of ​​the electrode sheet, and the plurality of second adsorption holes 1201 are used to adsorb the cleaned area of ​​the electrode sheet.

[0042] The first negative pressure component 20 is connected to the first adsorption plate 11 and communicates with a plurality of first adsorption holes 1101. The first negative pressure component 20 is used to generate a first adsorption force in the first adsorption holes 1101.

[0043] The second negative pressure component 30 is connected to the second adsorption plate 12 and communicates with a plurality of second adsorption holes 1201. The second negative pressure component 30 is used to generate a second adsorption force in the second adsorption holes 1201.

[0044] In this embodiment of the invention, by separately providing a plurality of first adsorption holes 1101 corresponding to the uncleaned area of ​​the electrode and a plurality of second adsorption holes 1201 corresponding to the area to be cleaned of the electrode, and by providing a first negative pressure component 20 corresponding to the first adsorption plate 11 and a second negative pressure component 30 corresponding to the second adsorption plate 12, the adsorption platform 10 can use different airflow paths to adsorb and fix the uncleaned area and the area to be cleaned respectively. When the adsorption platform 10 adsorbs and fixes the electrode, the first negative pressure component 20 can generate a first adsorption force in the plurality of first adsorption holes 1101. The second negative pressure component 30 generates a second adsorption force in several second adsorption holes 1201, thereby generating corresponding adsorption forces for the non-cleaning area and the area to be cleaned of the electrode. This allows the adsorption forces of the first adsorption hole 1101 and the second adsorption hole 1201 to be controlled and adjusted separately. This avoids situations where the adsorption forces of the first adsorption hole 1101 and the second adsorption hole 1201 are basically the same, resulting in excessive adsorption force of the second adsorption hole 1201, which may cause hole marks, or insufficient adsorption force, which may result in incomplete cleaning and surface residue. This improves the appearance yield and production yield of the electrode.

[0045] In this process, the surface layer of the unwashed area of ​​the electrode does not require cleaning or removal; its thickness remains unchanged, and its structural strength is relatively good. Therefore, a larger first adsorption force can be used to adsorb and fix the unwashed area, ensuring stable adsorption. Conversely, the surface layer of the area to be cleaned on the electrode needs cleaning and removal, resulting in a reduced thickness and weaker structural strength. Therefore, a smaller second adsorption force can be used to adsorb and fix the area to be cleaned, avoiding excessive adsorption force that could create pores in the area to be cleaned. Thus, the first adsorption force generated at the first adsorption pore 1101 is greater than the second adsorption force generated at the second adsorption pore 1201.

[0046] The first adsorption strength can be set according to the standard that the non-cleaned area of ​​the electrode is just firmly adsorbed, and the second adsorption strength can be set according to the standard that the area to be cleaned of the electrode can also be just firmly adsorbed after cleaning without producing pore marks.

[0047] like Figure 1As shown, in some embodiments, a first adsorption plate 11 defines a first air passage 1102, which is located away from the upper surface of the first adsorption plate 11 relative to a plurality of first adsorption holes 1101. The first air passage 1102 communicates with the plurality of first adsorption holes 1101, and the first negative pressure component 20 communicates with the first adsorption holes 1101 through the first air passage 1102. A second adsorption plate 12 defines a second air passage 1202, which is located away from the upper surface of the second adsorption plate 12 relative to a plurality of second adsorption holes 1201. The second air passage 1202 communicates with the plurality of second adsorption holes 1201, and the second negative pressure component 30 communicates with the second adsorption holes 1201 through the second air passage 1202.

[0048] In this design, the airflow path in the first adsorption plate 11 is formed by connecting the first adsorption hole 1101 and the first air passage 1102, and the airflow path in the second adsorption plate 12 is formed by connecting the second adsorption hole 1201 and the second air passage 1202. The specific structures of the first air passage 1102 and the second air passage 1202 can be set according to actual needs, and the utility model does not limit the specific structures of the first air passage 1102 and the second air passage 1202.

[0049] like Figure 1 As shown, in some embodiments, the first negative pressure assembly 20 includes a first pipe 21 and a first pressure regulating valve 22. The two ends of the first pipe 21 are connected to the first adsorption plate 11 and the first pressure regulating valve 22, respectively, and the first pipe 21 is connected to a plurality of first adsorption holes 1101. The first pressure regulating valve 22 is used to adjust the first adsorption force of the first adsorption holes 1101. The second negative pressure assembly 30 includes a second pipe 31 and a second pressure regulating valve 32. The two ends of the second pipe 31 are connected to the second adsorption plate 12 and the second pressure regulating valve 32, respectively, and the second pipe 31 is connected to a plurality of second adsorption holes 1201. The second pressure regulating valve 32 is used to adjust the second adsorption force of the second adsorption holes 1201. By respectively setting the first pressure regulating valve 22 connected to the first adsorption plate 11 and the second pressure regulating valve 32 connected to the second adsorption plate 12, the magnitude of the first adsorption force of the first adsorption hole 1101 and the magnitude of the second adsorption force of the second adsorption hole 1201 can be adjusted as needed, so that in actual use, the non-cleaning area and the area to be cleaned of the electrode can be stably adsorbed on the adsorption platform 10.

[0050] The first pipe 21 is connected to the first adsorption hole 1101 through the first air passage 1102, and the second pipe 31 is connected to the second adsorption hole 1201 through the second air passage 1202.

[0051] In some embodiments, the first negative pressure assembly 20 further includes a first negative pressure source, which is connected to a first pressure regulating valve 22 via a third pipe. The first negative pressure source can evacuate air from the first adsorption hole 1101 through the third pipe and the first pipe 21 to generate a negative pressure at the first adsorption hole 1101, thereby achieving adsorption and fixation of the non-cleaned area of ​​the electrode. The second negative pressure assembly 30 further includes a second negative pressure source, which is connected to a second pressure regulating valve 32 via a fourth pipe. The second negative pressure source can evacuate air from the second adsorption hole 1201 through the fourth pipe and the second pipe 31 to generate a negative pressure at the second adsorption hole 1201, thereby achieving adsorption and fixation of the area of ​​the electrode to be cleaned.

[0052] The first pressure regulating valve 22 can adjust the gas flow rate by adjusting the valve opening, thereby adjusting the first adsorption force of the first adsorption hole 1101; the second pressure regulating valve 32 can adjust the gas flow rate by adjusting the valve opening, thereby adjusting the second adsorption force of the second adsorption hole 1201.

[0053] Of course, in some other embodiments, the first pressure regulating valve 22 and the second pressure regulating valve 32 can also be connected to the same negative pressure source. The same negative pressure source can evacuate the first adsorption hole 1101 and the second adsorption hole 1201 through the corresponding pipes to generate negative pressure at the first adsorption hole 1101 and the second adsorption hole 1201 respectively, thereby realizing the adsorption and fixation of the non-cleaning area and the area to be cleaned of the electrode sheet.

[0054] Typically, the non-cleaned area of ​​an electrode is the coating retention area, while the area to be cleaned is the tab connection area. After cleaning, the area to be cleaned forms a tab groove area, located on the side of the electrode and partially surrounded by the coating retention area. Therefore, to accommodate the position of the tab groove area on the electrode, such as... Figure 2As shown, in some embodiments, a first adsorption plate 11 defines a first adsorption region 101, and a plurality of first adsorption holes 1101 are located within the first adsorption region 101. The first adsorption region 101 is used to adsorb the non-cleaning area of ​​the electrode sheet. A second adsorption plate 12 defines a second adsorption region 102, and a plurality of second adsorption holes 1201 are located within the second adsorption region 102. The second adsorption region 102 is used to adsorb the cleaning area of ​​the electrode sheet. A notch 103 is defined on one side of the first adsorption region 101, and the second adsorption region 102 is disposed within the notch 103. Thus, when the electrode sheet is placed on the adsorption platform 10, the coating retention area of ​​the electrode sheet can correspond to the first adsorption region 101 and cover the first adsorption holes 1101 within the first adsorption region 101, and the tab groove area of ​​the electrode sheet can correspond to the second adsorption region 102 and cover the second adsorption holes 1201 within the second adsorption region 102. This facilitates the adsorption and fixation of the coating retention area and tab groove area of ​​the electrode sheet by the first adsorption plate 11 and the second adsorption plate 12, respectively.

[0055] In some embodiments, the first adsorption region 101 is U-shaped, and the second adsorption region 102 is □-shaped.

[0056] Of course, in some other embodiments, the positional relationship between the first adsorption region 101 and the second adsorption region 102 can be adjusted according to the actual cleaning position of the electrode. For example, when the position to be cleaned in the electrode is an entire side of the electrode, the second adsorption region 102 can be set on one side of the first adsorption region 101 and extend along the length direction of that side.

[0057] In some embodiments, the first adsorption plate 11 and the second adsorption plate 12 are detachably connected, so that the first adsorption plate 11 or the second adsorption plate 12 can be removed from the adsorption platform 10 as needed for inspection or replacement, thereby facilitating the maintenance of the adsorption platform 10.

[0058] Of course, in some other embodiments, the first adsorption plate 11 and the second adsorption plate 12 can also be integrally formed, that is, the first adsorption plate 11 and the second adsorption plate 12 cannot be separated, the first adsorption plate 11 and the second adsorption plate 12 share the same adsorption plate structure, and in the same adsorption plate, the first adsorption hole 1101 and the second adsorption hole 1201 are separated from each other.

[0059] like Figure 1 and Figure 3As shown, in some embodiments, a groove 1103 is defined on the outer peripheral sidewall of the first adsorption plate 11, and the groove 1103 extends through the first adsorption plate 11 along the thickness direction H. The second adsorption plate 12 is embedded in the groove 1103. In this way, the overall structure of the adsorption platform 10 can be made more compact. Furthermore, the inner sidewall of the groove 1103 can play a certain limiting role for the second adsorption plate 12. The inner sidewall of the groove 1103 can restrict the second adsorption plate 12 from moving horizontally toward the inner sidewall of the groove 1103, which is beneficial to the positioning and stable connection between the first adsorption plate 11 and the second adsorption plate 12.

[0060] The second adsorption plate 12 can be inserted into the groove 1103 through the slot on the outer peripheral sidewall of the first adsorption plate 11, and the upper surface of the second adsorption plate 12 exposes the groove 1103 through the slot on the upper surface of the first adsorption plate 11.

[0061] In some embodiments, the first adsorption plate 11 is U-shaped and the second adsorption plate 12 is □-shaped.

[0062] like Figure 3 As shown, in some embodiments, the inner wall of the groove 1103 is provided with a first positioning structure 1104, and the peripheral wall of the second adsorption plate 12 is provided with a second positioning structure 1203. The first positioning structure 1104 and the second positioning structure 1203 cooperate to make the upper surface of the first adsorption plate 11 and the upper surface of the second adsorption plate 12 flush. In this way, the flatness of the upper surface of the adsorption platform 10 can be guaranteed, and the height difference between the upper surface of the first adsorption plate 11 and the upper surface of the second adsorption plate 12 can be avoided. This prevents creases from appearing at the connection between the upper surface of the first adsorption plate 11 and the upper surface of the second adsorption plate 12 after the electrode is adsorbed and fixed by the adsorption platform 10.

[0063] In some embodiments, one of the first positioning structure 1104 and the second positioning structure 1203 is a slot, and the other of the first positioning structure 1104 and the second positioning structure 1203 is a protrusion, which is inserted into the slot. Through the insertion and engagement between the protrusion and the slot, while realizing the mutual positioning of the first adsorption plate 11 and the second adsorption plate 12, it is also possible to restrict the movement of the second adsorption plate 12 relative to the first adsorption plate 11 along the thickness direction H of the first adsorption plate 11, thereby improving the connection strength between the first adsorption plate 11 and the second adsorption plate 12, so that the first adsorption plate 11 and the second adsorption plate 12 can be stably connected together.

[0064] In some embodiments, the inner sidewall of the groove 1103 and the peripheral sidewall of the second adsorption plate 12 are fitted together to eliminate the horizontal gap between the upper surface of the first adsorption plate 11 and the upper surface of the second adsorption plate 12, preventing dents from appearing at the connection between the first adsorption plate 11 and the second adsorption plate 12 after the electrode is adsorbed and fixed by the adsorption platform 10.

[0065] like Figure 1 As shown, during the cleaning process of the area to be cleaned on the electrode, a certain amount of dust is generated in the area to be cleaned. The dust easily accumulates at the second adsorption hole 1201 of the second adsorption plate 12. When the vacuum device is started or stopped, a rapid airflow change occurs instantaneously at the second adsorption hole 1201, causing instantaneous pressure fluctuations, which can lead to the dust at the second adsorption hole 1201 being pushed back out. Therefore, to reduce or avoid the above situation, in some embodiments, the thickness of the second adsorption plate 12 is greater than or equal to 10 mm. This ensures that the second adsorption hole 1201 in the second adsorption plate 12 has a sufficiently long airflow path to slow down the airflow speed at the second adsorption hole 1201 when the vacuum device is started or stopped, thereby reducing or avoiding the dust at the second adsorption hole 1201 being pushed back out.

[0066] Since the first adsorption plate 11 is a non-cleaning area, less dust accumulates in the first adsorption hole 1101, and dust back-pushing is less frequent. Therefore, the airflow path of the first adsorption hole 1101 can be relatively shorter than that of the second adsorption hole 1201. Consequently, in some embodiments, the thickness of the first adsorption plate 11 is less than the thickness of the second adsorption plate 12, thereby reducing the material used in the first adsorption plate 11 and lowering production costs.

[0067] In some embodiments, the thickness of the first adsorption plate 11 may be greater than or equal to 5 mm and less than 10 mm.

[0068] It is understood that this embodiment of the present invention uses an electrode as the adsorption object of the adsorption device 100 for illustration, and does not mean that the adsorption device 100 of this embodiment of the present invention can only be applied to the production of electrode. Other production processes that require corresponding adsorption strength according to different areas of the adsorption object can also be realized using this device.

[0069] This utility model embodiment also provides a cleaning device, which includes a laser cleaning device and the adsorption device 100 as described above. The laser cleaning device is used to emit a laser beam to the area to be cleaned of the electrode on the adsorption platform 10. The laser beam causes the surface layer of the area to be cleaned of the electrode to be ablated, vaporized, and peeled off, thereby achieving the cleaning of the area to be cleaned of the electrode.

[0070] The cleaning equipment of this utility model embodiment also has the beneficial effects of the adsorption device 100, which will not be described in detail here.

[0071] Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model. Furthermore, embodiments of this utility model and features thereof can be combined with each other, unless otherwise specified.
