[0050] As described in the background technology, the spray holes of the spray pipes in the prior art are easily clogged due to the formation of crystals, which results in the spray holes being unable to spray pickling liquid onto the surface of the copper foil, affecting the uniformity of the spraying on the surface of the copper foil and reducing the quality of the copper foil. The reason for this problem is that under normal pickling spray working conditions, the temperature of the pickling liquid sprayed from the spray holes is similar to the ambient temperature of the spray equipment. When the spray equipment is used for a long time, crystals of the pickling liquid will form at the spray holes, resulting in partial or even complete blockage of the spray holes, and further resulting in the amount of pickling liquid sprayed from the blocked spray holes being lower than that of other unblocked spray holes, resulting in poor uniformity of the pickling liquid sprayed onto the surface of the copper foil by the spray pipe with the blockage problem, affecting the quality of the copper foil after spraying.

[0051] In response to the above-mentioned technical problems, an embodiment of the present application provides a spraying equipment, by arranging a heating device on the outer peripheral side of the spray pipe, heating the spray pipe by the heating device, and further heating the pickling liquid in the spray pipe, so that the crystals at the spray hole are dissolved by the heated high-temperature pickling liquid, thereby solving the problem of crystallization and blockage at the spray hole, improving the spraying uniformity of the copper foil surface, and further improving the quality of the copper foil after spraying.

[0052] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0053] An embodiment of the present application provides a spraying device, which may include a spraying pipe 200 and a heating device 300 .

[0054] refer to Figure 1 and Figure 2 The spray pipe 200 is provided with a spray hole 210, and the spray pipe 200 is used to spray the pickling liquid to the copper foil 10 through the spray hole 210. Specifically, the spraying device may further include a liquid storage device 500, the liquid storage device 500 is connected to the spray pipe 200, and the liquid storage device 500 can be used to store the pickling liquid, and when the copper foil 10 needs to be pickled and sprayed, the pickling liquid is transported into the spray pipe 200.

[0055] The liquid storage device 500 is connected to the spray pipe 200 through a pipeline 550, and a valve is provided on the pipeline 550 to control the flow rate of the pickling liquid transported by the liquid storage device 500 to the spray pipe 200. The liquid storage device 500 may also include a first control unit (not shown in the figure) as described below, and the first control unit can control the opening or closing of the valve.

[0056] refer to Figure 1 In some embodiments, the liquid storage device 500 may further include a liquid level sensor 510 connected to the first control unit, and the liquid level sensor 510 may detect the liquid level value of the pickling solution in the liquid storage device 500. The liquid storage device 500 may further include a liquid supply pipe 520. When the liquid level of the pickling solution in the liquid storage device 500 is lower than a preset liquid level, under the control of the first control unit, the liquid supply pipe 520 is connected to the liquid storage device 500 and the pickling solution is transported to the liquid storage device 500. In some examples, the preset liquid level may be greater than or equal to 150 cm and less than or equal to 200 cm.

[0057] The first control unit obtains the liquid level value detected by the liquid level sensor 510. When the liquid level value is 150 cm and less than or equal to 200 cm, the pickling liquid in the liquid storage device 500 is at a normal level. When the liquid level value is lower than 150 cm, the first control unit controls the liquid supply pipe 520 to communicate with the liquid storage device 500, and transports the pickling liquid into the liquid storage device 500 through the liquid supply pipe 520.

[0058] The liquid storage device 500 may also include a pure water pipe 530 and a sewage pipe 540 connected to the first control unit. When the inside of the liquid storage device 500 needs to be cleaned, under the control of the first control unit, the pure water pipe 530 is connected to the liquid storage device 500 to introduce clean water into the liquid storage device 500, and the sewage pipe 540 is further controlled to be connected to the liquid storage device 500 to discharge the sewage after cleaning the liquid storage device 500 through the sewage pipe 540.

[0059] refer to Figure 1 and Figure 2 The heating device 300 is disposed on the outer peripheral side of the spray pipe 200 , and the heating device 300 is used to heat the pickling liquid in the spray pipe 200 to form a high-temperature pickling liquid, and the high-temperature pickling liquid is used to dissolve the crystals at the spray hole 210 .

[0060] The heating device 300 can be fixedly connected to the outer peripheral side of the spray pipe 200. The heating device 300 is used to heat the spray pipe 200 and indirectly heat the pickling liquid in the spray pipe 200 to form a high-temperature pickling liquid, and the crystals at the spray hole 210 are melted under the action of the high-temperature pickling liquid.

[0061] In some embodiments, the temperature of the high temperature pickling solution is greater than or equal to 70°C and less than or equal to 90°C.

[0062] In some embodiments, if it is necessary to clean the crystals at the spray hole 210, it is necessary to start the heating device 300, heat the pickling liquid in the spray pipe 200 through the heating device 300, and make the heated high-temperature pickling liquid slowly flow out from the spray hole 210 to melt the crystals through the high-temperature pickling liquid.

[0063] In some embodiments, the heating device 300 can use a variety of heating technologies to heat the spray pipe 200. First, the heating device 300 can heat the spray pipe 200 by electric heating. Second, the heating device 300 can heat the spray pipe 200 by hot air circulation.

[0064] Third, the heating device 300 can heat the spray pipe 200 by circulating the heated liquid.

[0065] The fourth heating device 300 can also heat the spray pipe 200 by steam heating.

[0066] The embodiment of the present application provides a spraying device, which disposes a heating device 300 on the outer peripheral side of the spray pipe 200, heats the spray pipe 200 by the heating device 300, and further heats the pickling liquid in the spray pipe 200, so that the crystals at the spray hole 210 are dissolved by the heated high-temperature pickling liquid at high temperature, thereby solving the problem of crystallization and blockage at the spray hole 210, improving the spraying uniformity of the surface of the copper foil 10, and further improving the quality of the copper foil 10 after spraying.

[0067] refer to Figure 1 and Figure 2 In some embodiments, the heating device 300 may include a heating sleeve 310, which is sleeved on the outer peripheral side of the spray pipe 200, and the heating sleeve 310 has an opening 320 in the area corresponding to the spray hole 210. The pickling liquid in the spray pipe 200 is sprayed onto the copper foil 10 through the opening 320. The heating sleeve 310 is used to heat the spray pipe 200 and heat the pickling liquid in the spray pipe 200 by heating the spray pipe 200.

[0068] The inner peripheral wall of the heating sleeve 310 is connected to the outer peripheral wall of the spray pipe 200 , so that the spray pipe 200 is heated through the heating sleeve 310 and the pickling liquid in the spray pipe 200 is heated.

[0069] By using a heating tube sleeve disposed on the outer peripheral side of the spray pipe 200 , the spray pipe 200 can be heated more evenly, which facilitates the uniform heating of the pickling liquid in the spray pipe 200 .

[0070] refer to Figure 1 and Figure 2 In some embodiments, the heating device 300 can heat the spray pipe 200 by steam heating. In a specific implementation, the heating sleeve 310 is arranged along a first direction (such as Figure 1The heating sleeve 310 extends as shown by the middle arrow X, and the interior of the heating sleeve 310 has a channel 330 for high-temperature gas to circulate, and the channel 330 extends along a first direction. One end of the heating sleeve 310 along the first direction has an input end for high-temperature gas to flow into the channel 330, and the other end of the heating sleeve 310 along the first direction has an output end for high-temperature gas to flow out of the channel 330.

[0071] The high-temperature gas is transported into the channel 330 from the input end of the heating sleeve 310, and the high-temperature gas heated by the heating sleeve 310 is outputted through the output end of the heating sleeve 310. The heating sleeve 310 is heated by the high-temperature gas, and the heated heating sleeve 310 heats the spray pipe 200, and then heats the pickling liquid in the spray pipe 200, so that the crystals at the spray hole 210 are dissolved by the heated high-temperature pickling liquid.

[0072] In some embodiments, the temperature of the high temperature gas is greater than or equal to 70° C. and less than or equal to 100° C.

[0073] In a possible implementation, the heating device 300 may also include a gas manufacturing unit (not shown in the figure), the gas outlet end of the gas manufacturing unit is connected to the input end, and the gas return end of the gas manufacturing unit is connected to the output end, and the gas manufacturing unit is used to transport high-temperature gas into the heating sleeve 310.

[0074] High-temperature gas can be produced through the gas production unit and transported to the input end through the gas outlet end. Then, the gas discharged from the output end of the heating sleeve 310 can also enter the gas production unit through the gas return end on the gas production unit.

[0075] refer to Figure 1 In some embodiments, the heating device 300 may further include an induction component 340 and a first control unit.

[0076] The sensing component 340 is disposed in the spray pipe 200, and is used to detect the flow value and hydraulic value of the pickling liquid in the spray pipe 200. The sensing component 340 can be disposed at one end of the spray pipe 200 along the length direction, for example, the sensing component 340 can be disposed at the input end of the pickling liquid of the spray pipe 200. When the pickling liquid flows into the spray pipe 200, the sensing component 340 can detect the flow value and hydraulic value of the pickling liquid, so as to judge the blockage condition of the spray hole 210 of the spray pipe 200 through the changes in the flow rate and hydraulic pressure in the spray pipe 200.

[0077] The first control unit is data-connected to the sensing component 340. The first control unit is used to control the reception and processing of the flow value and the hydraulic value. The sensing component 340 can send the detected actual flow value and hydraulic value to the first control unit. The first control unit compares the actual flow value and hydraulic value with the preset flow and preset hydraulic pressure. When the flow value meets the preset flow and the hydraulic value exceeds the preset hydraulic pressure, the spray hole 210 is blocked, and the first control unit controls the gas manufacturing unit to deliver high-temperature gas to the heating sleeve 310.

[0078] By providing the sensing component 340 and the first control unit, manual detection of the flow rate and hydraulic changes of the pickling liquid in the spray pipe 200 can be avoided. Instead, intelligent judgment is performed through the sensing component 340 and the first control unit, which saves labor, can improve the automation level of the heating device 300, improve the ease of use of the heating device 300, and thus can improve the automation level of the spray device.

[0079] In some embodiments, the preset hydraulic pressure is greater than or equal to 2 kg / cm 2 And less than or equal to 4kg / cm 2 , preset flow rate is greater than or equal to 3m 3 / h and less than or equal to 6m 3 / h.

[0080] In an exemplary embodiment, if the sensing component 340 obtained by the first control unit detects that the actual flow rate of the pickling liquid in the spray pipe 200 is greater than or equal to 3m 3 / h and less than or equal to 6m 3 / h, and the actual hydraulic pressure is 5kg / cm 2 , the first control unit can determine that the spray hole 210 on the spray pipe 200 is blocked at this time.

[0081] refer to Figure 1 In some embodiments, the sensing component 340 may include a hydraulic sensor 342 and a flow sensor 341 .

[0082] The hydraulic sensor 342 is disposed at the input end of the pickling liquid of the spray pipe 200 . The hydraulic sensor 342 can be connected to the first control unit for data transmission. The hydraulic sensor 342 is used to detect the hydraulic value of the pickling liquid in the spray pipe 200 .

[0083] The flow sensor 341 is arranged at the input end of the pickling liquid of the spray pipe 200. The flow sensor 341 and the hydraulic sensor 342 can be arranged at intervals. The flow sensor 341 can also be connected to the first control unit for data transmission. The flow sensor 341 is used to detect the flow value of the pickling liquid in the spray pipe 200.

[0084] refer to Figure 1In some embodiments, the heating device 300 may further include a first driving unit 350, which is connected to the spray pipe 200. The first driving unit 350 is used to drive the spray pipe 200 to rotate around the axial direction of the spray pipe 200. When the heating sleeve 310 heats the pickling liquid in the spray pipe 200, the first driving unit 350 drives the spray pipe 200 to rotate and the heating sleeve 310 to rotate so that the spray hole 210 and the opening 320 are both facing the opposite direction of gravity.

[0085] refer to Figure 1 and Figure 3 ,by Figure 3 Based on the setting orientation of the spray pipe 200, the first driving unit 350 can drive the spray pipe 200 to rotate and make the spray hole 210 on the spray pipe 200 face upward, so that the high-temperature pickling liquid heated by the heating sleeve 310 can slowly overflow from the spray hole 210. Compared with when the spray hole 210 faces downward, the residence time of the high-temperature pickling liquid at the spray hole 210 can be increased, thereby improving the dissolution effect of the crystals at the spray hole 210.

[0086] In a specific implementation, the first driving unit 350 can drive the spray pipe 200 to rotate and make the spray hole 210 on the spray pipe 200 face upward. When the cleaning process of the spray hole 210 is completed, the first driving unit 350 can also drive the spray pipe 200 to rotate to the angle when spraying on the surface of the copper foil 10, so as to adjust the spray angle of the spray pipe 200, improve the spray effect of the spray pipe 200, and further improve the pickling quality of the copper foil 10.

[0087] In some embodiments, there may be a plurality of first drive units 350, and one first drive unit 350 may be installed at each end of a spray pipe 200, thereby improving the rotation efficiency of the spray pipe 200. The orthographic projection of the first drive unit 350 may not overlap with the pickling tank, so that the first drive unit 350 is located outside the pickling tank, avoiding the first drive unit 350 from affecting the spraying of the copper foil 10 and reducing the probability of the pickling tank being contaminated by the external environment.

[0088] refer to Figure 3 If there are two spray pipes 200 , one of the spray pipes 200 is located below the copper foil 10 , and the other one is located above the copper foil 10 .

[0089] When the spray hole 210 of the spray pipe 200 located below the copper foil 10 is blocked, the spray hole 210 of the spray pipe 200 can be rotated to face upward through the first driving unit 350, and the flow rate and hydraulic pressure of the spray pipe 200 are adjusted to make the high-temperature pickling liquid flow out of the spray hole 210 and avoid spraying onto the surface of the copper foil 10, thereby avoiding the influence of the high-temperature pickling liquid on the surface of the copper foil 10. At this time, the hydraulic pressure in the spray pipe 200 can be adjusted to be greater than or equal to 0.3 kg / cm 2 And less than or equal to 0.8kg / cm 2 , flow rate is greater than or equal to 1m 3 / h and less than or equal to 3m 3 / h.

[0090] When the spray hole 210 of the spray pipe 200 located above the copper foil 10 is blocked, the spray hole 210 of the spray pipe 200 can be rotated to face upward through the first driving unit 350, and the flow rate and hydraulic pressure of the spray pipe 200 are adjusted to make the high-temperature pickling liquid flow out of the spray hole 210 and avoid spraying onto the surface of the copper foil 10. At this time, the hydraulic pressure in the spray pipe 200 can be adjusted to be greater than or equal to 0.3 kg / cm 2 And less than or equal to 0.8kg / cm 2 , flow rate is greater than or equal to 1m 3 / h and less than or equal to 3m 3 / h.

[0091] refer to Figure 3 In a possible implementation, the heating device 300 may further include a collecting tank 360, which extends along the length direction of the spray pipe 200. When the heating sleeve 310 heats the spray pipe 200, the collecting tank 360 is arranged relatively below the spray pipe 200, and the collecting tank 360 is used to collect the high-temperature pickling liquid flowing out of the spray pipe 200.

[0092] By providing the collecting tank 360 , the high-temperature pickling liquid overflowing from the spray hole 210 can be collected, thereby preventing the dissolved and crystallized high-temperature pickling liquid from falling into the pickling tank of the spraying equipment.

[0093] In a specific implementation, the collecting tank 360 can be connected to the first driving unit 350 and can rotate together with the spray pipe 200. When the spray hole 210 of the spray pipe 200 rotates downward and sprays the pickling liquid toward the upper surface of the copper foil 10, the collecting tank 360 can rotate to above the spray pipe 200. At this time, the spray hole 210 is located between the upper surface of the copper foil 10 and the collecting tank 360, so as to prevent the collecting tank 360 from blocking the spray hole 210 from spraying the pickling liquid onto the surface of the copper foil 10.

[0094] refer to Figure 1 In some embodiments, the spraying device may further include a device body 100 and an adjustment mechanism 400 .

[0095] The equipment body 100 is used to transport the copper foil 10, and the spray pipe 200 is arranged on the equipment body 100. The equipment body 100 has a conveying roller, and the copper foil 10 can be conveyed from one end of the equipment body 100 to the other end through the conveying roller. In the specific use process, when the equipment body 100 conveys the copper foil 10 through the conveying roller, the spray pipe 200 can simultaneously perform pickling spray on the copper foil 10 during the conveying process.

[0096] The adjusting mechanism 400 is connected to the spray pipe 200 and can be fixed on the equipment body 100. The adjusting mechanism 400 can drive the spray pipe 200 along a first direction so that the copper foil 10 on the equipment body 100 is within the spraying range of the spray pipe 200 in the first direction.

[0097] In some embodiments, the adjustment mechanism 400 can be connected to one end of the spray pipe 200 in the length direction, and the spray pipe 200 is driven to move along the first direction by driving one end of the spray pipe 200. The adjustment mechanism 400 can also be connected to both ends of the spray pipe 200 in the length direction at the same time. By connecting to both ends of the spray pipe 200, the connection stability between the adjustment mechanism 400 and the spray pipe 200 can be improved.

[0098] By providing an adjustment mechanism 400 connected to the spray pipe 200, the spray pipe 200 is driven to move along its length direction through the adjustment mechanism 400, so that the copper foil 10 is within the spraying range of the spray pipe 200 in the first direction, thereby spraying the surface of the copper foil 10 along the first direction, avoiding uneven spraying on the surface of the copper foil 10, and improving the pickling effect of the copper foil 10 and the product quality.

[0099] refer to Figure 1 In some embodiments, the adjustment mechanism 400 may include a second drive unit 410, two displacement sensors 420, and a second control unit (not shown in the figure). The second drive unit 410 is connected to the spray pipe 200, and the second drive unit 410 can drive the spray pipe 200 to move along the axial direction of the spray pipe 200. The two displacement sensors 420 are arranged at both ends of the spray pipe 200 in the length direction, and all the spray holes 210 on the spray pipe 200 can be located between the two displacement sensors 420, and the copper foil 10 is also located between the two displacement sensors 420.
