Description

Technical Field

[0001] This application relates to the field of copper foil manufacturing technology, and in particular to a testing method for a spraying device. Background Technology

[0002] Electrolytic copper foil is widely used in industries such as new energy batteries and 5G communications due to its excellent conductivity, abundant resources, ease of processing, and low cost. In recent years, with the increasing severity of environmental pollution and the energy crisis, the development and use of new energy sources have become particularly important, leading to unprecedented growth for electrolytic copper foil manufacturers and a continuously increasing market demand for the product.

[0003] In related technologies, the production process of electrolytic copper foil requires surface treatment. During the surface treatment process, copper sulfate pickling solution is sprayed onto two opposite surfaces of the copper foil in the thickness direction through spray pipes on a spraying device. However, because copper sulfate solution is prone to crystallization, the spraying effect on the copper foil surface corresponding to the crystallized spray holes is less than that in other areas, resulting in uneven spraying of the copper foil surface. Therefore, after pickling one or more copper foils, the spraying equipment needs to be stopped and inspected to check for blockages in the spray pipes.

[0004] However, the testing methods for the spray equipment in the aforementioned related technologies require testing after the spray equipment is shut down, which is not conducive to observing the blockage of the spray pipes, resulting in a decrease in the pickling efficiency of copper foil and affecting the production quality and efficiency of copper foil. Summary of the Invention

[0044] As described in the background section, the pickling process for copper foil in the prior art makes it difficult to monitor the clogging of the spray pipes in the spraying equipment, resulting in a reduced pickling effect, affecting the production quality and efficiency of the copper foil, and also reducing the practicality of the spraying equipment. This problem arises because the pickling process in the prior art involves continuously pickling multiple copper foils using the spraying equipment. The tail end of the copper foil assembled into the spraying equipment is directly connected to the head end of another copper foil to be pickled, with no gap between the two connected foils. The next copper foil is sprayed immediately after the previous one has been finished.

[0045] Therefore, in order to ensure the spraying effect on the surface of the next copper foil, the spraying equipment needs to be stopped and the clogging of the spray pipes needs to be checked before pickling the next copper foil. It is not possible to check the clogging of the spray pipes during the operation of the spraying equipment conveying the copper foil, which is not conducive to the observation of the clogging of the spray pipes, resulting in a decrease in the pickling efficiency of the copper foil and affecting the production quality and efficiency of the copper foil.

[0046] To address the aforementioned technical problems, this application provides a method for detecting a spraying device. The method includes a spraying device, multiple copper foils, and a transparent layer. The spraying device includes at least one spray pipe with multiple spray holes. The leading end of one of the copper foils is attached to the spraying device, and the trailing end of the copper foil is spaced apart from the leading end of another copper foil and connected via the transparent layer. The copper foil is driven to move, and spraying occurs through the spray holes onto the copper foil and the transparent layer. Based on the spraying status on the transparent layer, the blockage of the spray holes can be detected. This allows for observation of the blockage of the spray pipe during the copper foil pickling process, facilitating the observation of spray pipe blockage, improving the pickling efficiency of the copper foil, and enhancing the production quality and efficiency of the copper foil.

[0047] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0048] Figure 1 The illustration shows a flowchart of a testing method for a spray device 100 provided in an embodiment of this application.

[0049] refer to Figure 1 This application provides a method for testing a spraying device 100, which may include the following steps:

[0050] S101, a spraying device 100, a plurality of copper foils 200, and a transparent layer 300 are provided. The spraying device 100 may include at least one spray pipe 110, which has a plurality of spray holes and is used to spray pickling solution onto two opposite sides of the copper foils 200 in the thickness direction.

[0051] In some examples, the pickling solution can be a copper sulfate solution. During the long-term spraying of copper sulfate solution, crystals will form in the spray pipe 110, which will block the spray holes of the spray pipe 110. This will result in a weaker spraying effect on the copper foil 200 surface corresponding to the blocked spray holes on the spray pipe 110 compared to the copper foil 200 surface corresponding to other unblocked spray holes, and thus a poorer pickling effect on the copper foil 200 surface.

[0052] In some examples, the spraying device 100 may also include a transmission structure 120, through which the copper foil 200 is driven to enter from one end of the spraying device 100, and sprayed with pickling solution through the spray pipe 110, and driven by the transmission structure 120, the copper foil 200 sprayed with pickling solution is output from the other end of the spraying device 100.

[0053] In some embodiments, the transport structure 120 may be a transport roller for transporting the copper foil 200 and the transparent layer 300.

[0054] S102, in some embodiments, there are multiple copper foils 200, which can be arranged sequentially in their length extension direction, and the first end of one of the copper foils 200 is fitted to the spraying device 100, and the tail end of the copper foil 200 is spaced apart from the first end of another copper foil 200 and connected through the transparent layer 300.

[0055] In some embodiments, if the plurality of copper foils 200 include a first copper foil 200a and a second copper foil 200b, the first end of the first copper foil 200a in the length direction is fitted to the spraying device 100 so that the output structure of the spraying device 100 can drive the first copper foil 200a into the spraying device 100 for spray pickling. The tail end of the first copper foil 200a in the length direction and the first end of the second copper foil 200b in the length direction are spaced apart in the length direction, and the tail end of the first copper foil 200a and the first end of the second copper foil 200b are connected by a transparent layer 300.

[0056] It is understandable that if there are three or more copper foils 200, each pair of adjacent copper foils 200 can be spaced apart and connected by a transparent layer 300, so that each pair of adjacent copper foils 200 is connected by a transparent layer 300.

[0057] Furthermore, if there are three or more copper foils 200, at least two adjacent copper foils 200 may be connected directly without any gap.

[0058] S103, drive the copper foil 200 to move, and spray the copper foil 200 and the transparent layer 300 through the spray holes. The copper foil 200 can be driven to move along its length relative to the spray device 100 through the transmission structure 120 of the spray device 100, and during the movement, pickling solution is sprayed onto the surface of the copper foil 200 through the spray holes of the spray pipe 110.

[0059] Based on the above embodiments, if the multiple copper foils 200 have a first copper foil 200a and a second copper foil 200b, then when the spraying of the tail end of the first copper foil 200a ends, the spraying device 100 can continue to spray the surface of the transparent layer 300 without stopping the spraying, and continue to spray the surface of the second copper foil 200b after the spraying of the surface of the transparent layer 300 ends.

[0060] In some embodiments, the spraying device 100 can spray one side of the copper foil 200 in the thickness direction through the spray pipe 110, or it can spray both opposite surfaces of the copper foil 200 in the thickness direction simultaneously. When spraying one side of the copper foil 200, the spray pipe 110 can be provided on one side of the copper foil 200 in the thickness direction. For example, the spray pipe 110 can be provided above the copper foil 200 to spray the upper surface of the copper foil 200, or the spray pipe 110 can be provided below the copper foil 200 to spray the lower surface of the copper foil 200.

[0061] Similarly, the spray pipe 110 can spray one side of the transparent layer 300 in the thickness direction, or it can spray both opposite surfaces of the transparent layer 300 in the thickness direction. If spraying is to one side of the transparent layer 300, the spray pipe 110 can be provided on one side of the transparent layer 300 in the thickness direction. For example, the spray pipe 110 can be provided above the transparent layer 300 to spray the upper surface of the transparent layer 300, or the spray pipe 110 can be provided below the transparent layer 300 to spray the lower surface of the transparent layer 300.

[0062] S104, during the spraying process of the transparent layer 300 by the spray pipe 110, the blockage of the spray holes is detected based on the spraying status on the transparent layer 300. Because blocked spray holes cannot spray pickling solution normally, the uniformity of the pickling solution sprayed on the surface of the transparent layer 300 is reduced. For example, no pickling solution may be sprayed near the surface of the transparent layer 300 corresponding to a blocked spray hole, or the amount of pickling solution sprayed on the surface of the transparent layer 300 may be less than the amount sprayed on the surface of the transparent layer 300 from other unblocked spray holes. Therefore, the blockage status of the spray holes of the spray pipe 110 can be determined by the uniformity of the pickling solution distribution on the surface of the transparent layer 300.

[0063] If the amount of pickling solution sprayed onto a portion of the transparent layer 300 is small, it indicates that the spray nozzles of the spray pipe 110 are blocked. The spraying equipment 100 needs to be stopped, and the blocked nozzles cleaned. If the pickling solution on the side of the transparent layer 300 facing the spray pipe 110 is evenly distributed and there is no significant reduction in the amount of pickling solution, it indicates that the spray nozzles of the spray pipe 110 are not blocked. Therefore, the spraying equipment 100 does not need to be stopped, and the next copper foil 200 can continue with the pickling process.

[0064] In one possible implementation, if spray pipes 110 are provided both above and below the copper foil 200, when the transparent layer 300 moves to the area corresponding to the spray pipes 110, the operator can observe the blockage of the spray holes of the spray pipes 110 above the transparent layer 300, and can also observe the blockage of the spray holes of the spray pipes 110 below the transparent layer 300 through the transparent layer 300.

[0065] This application provides a detection method for a spraying device 100. The method includes a spraying device 100, multiple copper foils 200, and a transparent layer 300. The spraying device 100 may include at least one spray pipe 110 with multiple spray holes. The head end of one of the copper foils 200 is attached to the spraying device 100, and the tail end of one copper foil 200 is spaced apart from and connected to the head end of another copper foil 200 through the transparent layer 300. The copper foil 200 is driven to move, and sprays are applied to the copper foil 200 and the transparent layer 300 through the spray holes. Based on the spraying status on the transparent layer 300, the blockage of the spray holes can be detected. This allows for observation of the blockage status of the spray pipe 110 during the pickling process of the copper foil 200, facilitating the observation of the blockage status of the spray pipe 110, improving the pickling efficiency of the copper foil 200, and enhancing the production quality and efficiency of the copper foil 200.

[0066] Figure 3 The illustration shows a flowchart of a testing method for a spray device 100 provided in an embodiment of this application.

[0067] refer to Figure 2 and Figure 3In some embodiments, the number of spray pipes 110 may be one, and the copper foil 200 has opposing first surfaces 210 and second surfaces 220. The spray pipe 110 is located below the copper foil 200 and faces the second surface 220, while the first surface 210 of the copper foil 200 faces away from the spray pipe 110. In some embodiments, the opposing first surfaces 210 in the thickness direction of the copper foil 200 may be smooth and facing upwards, and the second surface 220 may be rough and facing downwards. The spray pipe 110 is located below the copper foil 200 and faces the rough surface of the copper foil 200 to perform spray pickling on the rough surface of the copper foil 200.

[0068] refer to Figure 3 In some embodiments, the step of spraying the copper foil 200 and the transparent layer 300 through the spray holes may include: spraying the second side 220 of the copper foil 200 and one side of the transparent layer 300 through the spray holes of the spray pipe 110, wherein one side of the transparent layer 300 and the second side 220 of the copper foil 200 are on the same side and are both sprayed through the spray pipe 110.

[0069] refer to Figure 3 The testing method for the spray equipment 100 may include the following steps:

[0070] S201, a spraying device 100, a plurality of copper foils 200 and a transparent layer 300 are provided. The spraying device 100 may include at least one spray pipe 110, and the spray pipe 110 is provided with a plurality of spray holes.

[0071] For example, please refer to the content of S101 above for a detailed description of S201, which will not be repeated here.

[0072] S202, the first end of one of the multiple copper foils 200 is attached to the spraying device 100, and the tail end of the copper foil 200 is spaced apart from the first end of another copper foil 200 among the multiple copper foils 200 and connected through the transparent layer 300.

[0073] For example, please refer to the content of S102 above for a detailed description of S202, which will not be repeated here.

[0074] S203, drive the copper foil 200 to move, and spray the second side 220 of the copper foil 200 and one side of the transparent layer 300 through the spray holes.

[0075] By setting a transparent layer 300 between two copper foils 200, and by spraying the transparent layer 300 with a spray pipe 110, the blockage of the spray holes of the spray pipe 110 located below the copper foil 200 can be observed through the transparent layer 300. This allows the blockage of the spray pipe 110 to be detected before the next copper foil 200 is sprayed, without stopping the spraying equipment 100. This is beneficial for observing the blockage of the spray pipe 110, improving the pickling efficiency of the copper foil 200, and improving the production quality and efficiency of the copper foil 200.

[0076] S204, based on the spraying condition on the transparent layer 300, detect the blockage of the spray holes.

[0077] For example, please refer to the content of S104 above for a detailed description of S204, which will not be repeated here.

[0078] The detection method of the spraying device 100 provided in this application embodiment provides a spraying device 100, a plurality of copper foils 200, and a transparent layer 300. The spraying device 100 may include at least one spray pipe 110 with a plurality of spray holes. The first end of one of the plurality of copper foils 200 is assembled to the spraying device 100, and the tail end of one of the copper foils 200 is spaced apart from the first end of another of the plurality of copper foils 200 and connected through the transparent layer 300. The copper foil 200 is driven to move, and the copper foil 200 and the transparent layer 300 are sprayed through the spray holes. Based on the spraying status on the transparent layer 300, the clogging status of the spray holes is detected. This enables the observation of the clogging status of the spray pipe 110 of the spraying device 100 during the pickling process of the copper foil 200, which is beneficial for the observation of the clogging status of the spray pipe 110, improves the pickling efficiency of the copper foil 200, and improves the production quality and efficiency of the copper foil 200.

[0079] Figure 4 The illustration shows a flowchart of a testing method for a spray device 100 provided in an embodiment of this application.

[0080] refer to Figure 2 and Figure 4 In some embodiments, there may be two spray pipes 110, namely a first spray pipe 110a and a second spray pipe 110b. The first spray pipe 110a is located above the copper foil 200, and the second spray pipe 110b is located below the copper foil 200, so that both opposite sides of the copper foil 200 in the thickness direction can be acid-washed and sprayed. If the two opposite sides of the copper foil 200 in the thickness direction are a smooth surface and a rough surface, and the smooth surface faces upward relative to the rough surface, then the first spray pipe 110a can spray the smooth surface, and the second spray pipe 110b can spray the rough surface, thereby achieving spraying of both the smooth and rough surfaces.

[0081] Furthermore, since a first spray pipe 110a is provided above the copper foil 200 and a second spray pipe 110b is provided below the copper foil 200, it is also possible to spray both sides of the transparent layer 300 in the thickness direction.

[0082] refer to Figure 4 In some embodiments, the step of detecting the blockage of the spray holes based on the spraying conditions on the transparent layer 300 may include: detecting the blockage of the spray holes of the first spray pipe 110a based on the spraying conditions on the surface of the transparent layer 300 facing the first spray pipe 110a.

[0083] Based on the spraying status of the surface of the transparent layer 300 facing the second spray pipe 110b, the blockage of the spray holes of the second spray pipe 110b is detected.

[0084] refer to Figure 4 The testing method for the spray equipment 100 may include the following steps:

[0085] S301, a spraying device 100, a plurality of copper foils 200 and a transparent layer 300 are provided. The spraying device 100 may include at least one spray pipe 110, and the spray pipe 110 is provided with a plurality of spray holes.

[0086] For example, please refer to the content of S101 above for a detailed description of S301, which will not be repeated here.

[0087] S302, the first end of one of the multiple copper foils 200 is attached to the spraying device 100, and the tail end of the copper foil 200 is spaced apart from the first end of another copper foil 200 among the multiple copper foils 200 and connected through the transparent layer 300.

[0088] For example, please refer to the content of S102 above for a detailed description of S302, which will not be repeated here.

[0089] S303 drives the copper foil 200 to move, spraying the copper foil 200 and the transparent layer 300 through the spray holes.

[0090] For example, please refer to the content of S103 above for a detailed description of S303, which will not be repeated here.

[0091] S304, based on the spraying status of the surface of the transparent layer 300 facing the first spray pipe 110a, detect the blockage of the spray holes of the first spray pipe 110a.

[0092] In some embodiments, by providing a transparent layer 300 between two copper foils 200, if the spray holes of the first spray pipe 110a become blocked during the spraying of the transparent layer 300 by the first spray pipe 110a, the uniformity of the pickling solution sprayed onto the surface of the transparent layer 300 toward the first spray pipe 110a will be low. For example, less pickling solution will be sprayed on the area of ​​the transparent layer 300 corresponding to the blocked spray hole on the first spray pipe 110a. This allows it to be determined that the spray hole on the spray pipe 110 corresponding to the area with less pickling solution sprayed is blocked, which is beneficial for observing the blockage of the spray pipe 110, improving the pickling efficiency of the copper foil 200, and improving the production quality and efficiency of the copper foil 200.

[0093] S305, based on the spraying status of the surface of the transparent layer 300 facing the second spray pipe 110b, detect the blockage of the spray holes of the second spray pipe 110b.

[0094] By setting a transparent layer 300 between two copper foils 200, if the spray holes of the second spray pipe 110b become blocked during the spraying of the transparent layer 300 by the second spray pipe 110b, the blockage of the spray holes of the second spray pipe 110b located below the copper foil 200 can be observed through the transparent layer 300. This allows for the detection of the blockage of the spray pipe 110 before the next copper foil 200 is sprayed without stopping the spraying equipment 100. This is beneficial for observing the blockage of the spray pipe 110, improving the pickling efficiency of the copper foil 200, and enhancing the production quality and efficiency of the copper foil 200.

[0095] The detection method of the spraying device 100 provided in this application embodiment provides a spraying device 100, a plurality of copper foils 200, and a transparent layer 300. The spraying device 100 may include at least one spray pipe 110 with a plurality of spray holes. The first end of one of the plurality of copper foils 200 is assembled to the spraying device 100, and the tail end of one of the copper foils 200 is spaced apart from the first end of another of the plurality of copper foils 200 and connected through the transparent layer 300. The copper foil 200 is driven to move, and the copper foil 200 and the transparent layer 300 are sprayed through the spray holes. Based on the spraying status on the transparent layer 300, the clogging status of the spray holes is detected. This enables the observation of the clogging status of the spray pipe 110 of the spraying device 100 during the pickling process of the copper foil 200, which is beneficial for the observation of the clogging status of the spray pipe 110, improves the pickling efficiency of the copper foil 200, and improves the production quality and efficiency of the copper foil 200.

[0096] In some embodiments, the testing method of the spraying device 100 includes providing a transparent layer 300, which may include providing a corrosion-resistant transparent layer 300 made of a corrosion-resistant material. By preparing the transparent layer 300 as a corrosion-resistant transparent layer 300 made of a corrosion-resistant material, it is possible to prevent the transparent layer 300 from being corroded by pickling solution during the spraying process of the spray pipe 110, thereby improving the corrosion resistance of the transparent layer 300, reducing the probability of the transparent layer 300 being damaged due to corrosion, and improving the connection stability between the copper foil 200 and the transparent layer 300.

[0097] In some embodiments, the detection method of the spraying device 100 includes providing a transparent layer 300, which may include providing a flexible transparent layer 300 made of a flexible material. By providing a flexible transparent layer 300 made of a flexible material, the flexibility of the transparent layer 300 can be improved, thereby reducing the probability of the transparent layer 300 breaking or cracking during the transmission process of the spraying device 100. This improves the surface integrity of the transparent layer 300, which is beneficial to improving the connection stability between the transparent layer 300 and the copper foil 200, and also beneficial to improving the stability of the transparent layer 300 in use, reducing the impact of damage to the transparent layer 300 on the observation of the distribution of pickling solution sprayed on the transparent layer 300.

[0098] In one possible implementation, the detection method of the spray device 100, which provides a transparent layer 300, may include providing a transparent layer 300 made of either polyester resin or polyethylene.

[0099] In some embodiments, the thickness of the transparent layer 300 can be approximately equal to the thickness of the copper foil 200. For example, the thickness of the transparent layer 300 may be slightly less than the thickness of the copper foil 200, or the thickness of the transparent layer 300 may be slightly greater than the thickness of the copper foil 200. In specific implementations, the thickness of the transparent layer 300 can be greater than or equal to 50 μm and less than or equal to 120 μm. For example, the thickness of the transparent layer 300 can be 60 μm, 70 μm, 90 μm, or 110 μm.

[0100] If the thickness of the transparent layer 300 is less than 50μm, for example, if the thickness of the transparent layer 300 is 40μm, the transparent layer 300 will be too thin and have low strength, which will easily cause the transparent layer 300 to break or crack, affecting the stability of the transparent layer 300 in use, and also affecting the connection stability between the transparent layer 300 and the copper foil 200.

[0101] If the thickness of the transparent layer 300 is greater than 120μm, for example, if the thickness of the transparent layer 300 is 140μm, it will result in a large difference between the thickness of the transparent layer 300 and the thickness of the copper foil 200, which will affect the conveying of the copper foil 200 on the spraying equipment 100.

[0102] In some embodiments, the width of the transparent layer 300 can be approximately equal to the width of the copper foil 200. If the width of the transparent layer 300 is less than the width of the copper foil 200, there will be some unconnected areas at the ends of the copper foil 200 that are connected to the transparent layer 300. These unconnected areas will curl or bend during transport on the spraying device 100, resulting in damage to the copper foil 200. If the width of the transparent layer 300 is greater than the width of the copper foil 200, there will also be some unconnected areas at the ends of the transparent layer 300 that are connected to the copper foil 200. These unconnected areas will curl or bend during transport on the spraying device 100, potentially causing the transport process to stall due to curling or bending of the transparent layer 300, thus affecting the spraying efficiency of the copper foil 200.

[0103] In some embodiments, the length of the transparent layer 300 is greater than or equal to 3m and less than or equal to 7m. For example, the length of the transparent layer 300 can be 4m, 5m, 6m, or 6.5m. If the length of the transparent layer 300 is too short, for example, 1m, it will reduce the time available for operators to observe the clogging of the spray nozzles through the transparent layer 300, which is not conducive to fully observing the clogging of the spray nozzles. If the length of the transparent layer 300 is too long, for example, 9m, it will increase the cost of using the transparent layer 300, which is not conducive to reducing the manufacturing cost of the copper foil 200.

[0104] Figure 5 The illustration shows a flowchart of a testing method for a spray device 100 provided in an embodiment of this application.

[0105] refer to Figure 2 and Figure 5 In some embodiments, a spraying device 100, a plurality of copper foils 200, and a transparent layer 300 are provided, including: providing a spraying device 100, a plurality of copper foils 200, a transparent layer 300, and a plurality of adhesive layers (not shown in the figure).

[0106] refer to Figure 5 The step of having the tail end of one copper foil 200 spaced apart from the head end of another copper foil 200 among a plurality of copper foils 200 and connected by a transparent layer 300 may include: the tail end of one copper foil 200 being spaced apart from the head end of another copper foil 200 and connected by an adhesive layer.

[0107] refer to Figure 5 The testing method for the spray equipment 100 may include the following steps:

[0108] S401, a spraying device 100, a plurality of copper foils 200, a transparent layer 300, and a plurality of adhesive layers are provided. The spraying device 100 may include at least one spray pipe 110, on which a plurality of spray holes are provided.

[0109] S402, the first end of one of the multiple copper foils 200 is assembled to the spraying device 100, and the tail end of one of the copper foils 200 is spaced apart from the first end of another copper foil 200 among the multiple copper foils 200 and connected by an adhesive layer.

[0110] By connecting the tail end of one copper foil 200 to the head end of another copper foil 200 through an adhesive layer, the connection stability between the two copper foils 200 can be improved, and the separation between the copper foil 200 and the transparent layer 300 can be avoided during the process of conveying the copper foil 200 by the spraying equipment 100.

[0111] S403 drives the copper foil 200 to move and sprays the copper foil 200 and the transparent layer 300 through the spray nozzle.

[0112] For example, please refer to the content of S103 above for a detailed description of S403, which will not be repeated here.

[0113] S404, based on the spraying conditions on the transparent layer 300, detect the blockage of the spray holes.

[0114] For example, please refer to the content of S104 above for a detailed description of S404, which will not be repeated here.

[0115] The detection method of the spraying device 100 provided in this application embodiment provides a spraying device 100, a plurality of copper foils 200, and a transparent layer 300. The spraying device 100 may include at least one spray pipe 110 with a plurality of spray holes. The first end of one of the plurality of copper foils 200 is assembled to the spraying device 100, and the tail end of one of the copper foils 200 is spaced apart from the first end of another of the plurality of copper foils 200 and connected through the transparent layer 300. The copper foil 200 is driven to move, and the copper foil 200 and the transparent layer 300 are sprayed through the spray holes. Based on the spraying status on the transparent layer 300, the clogging status of the spray holes is detected. This enables the observation of the clogging status of the spray pipe 110 of the spraying device 100 during the pickling process of the copper foil 200, which is beneficial for the observation of the clogging status of the spray pipe 110, improves the pickling efficiency of the copper foil 200, and improves the production quality and efficiency of the copper foil 200.

[0116] In some embodiments, the testing method of the spraying equipment 100 provides multiple adhesive layers, which may include providing a corrosion-resistant adhesive layer made of a corrosion-resistant material. Making the adhesive layer from a corrosion-resistant material improves its corrosion resistance, thereby preventing damage or failure due to corrosion by the pickling solution during the spraying pickling process. This improves the stability of the connection between the transparent layer 300 and the copper foil 200, and prevents the transparent layer 300 from separating from the adhesive layer.

[0117] In one possible implementation, the detection method of the spray device 100 provides multiple adhesive layers, which may include adhesive layers made of one of polyurethane, epoxy resin and fluororubber.
