Description

Technical Field

[0001] This application relates to the field of copper foil processing devices, and particularly to a copper foil processing device. Background Art

[0002] During the manufacturing process of electrolytic lithium-ion copper foil, the semi-finished copper foil produced by the foil making machine needs to be placed in a copper foil processing device for appropriate heating to improve the crystal properties of the copper foil, release stress, and reduce the warp degree of the smooth surface. This is an indispensable step in the copper foil production process.

[0003] The current mainstream method in the copper foil industry is to bake the copper foil using an oven or place it in a constant-temperature semi-finished product warehouse at a temperature of 60 - 90°C for 12 - 14 hours for stress release. After baking, the copper foil is cooled to room temperature, and this process generally takes about 24 hours. Currently, several rolls of copper foil can be placed in one oven. The copper foil rolls can be lifted into the copper foil roller rack inside the oven from above by a crane. The oven operates by blowing hot air into the inner cavity of the oven body to bake the copper foil rolls. When the oven is in use, the positions of multiple copper foil racks are usually not fully occupied, and the utilization rate is less than 60%, resulting in a certain amount of energy waste. At the same time, the oven has a span of nearly 10 meters and a large internal space. During the high-temperature heating process of the copper foil rolls, there is an easy problem of uneven heat distribution, causing the copper foil rolls to be unevenly heated and resulting in defective problems of the copper foil, such as warping.

[0033] Referring to Figure 1 , a copper foil processing device provided by the present application includes an oven main body 100, at least two copper foil racks 110, and at least two sets of heating components 130. At least one partition 120 is provided inside the oven main body 100. The at least one partition 120 divides the inner cavity of the oven main body 100 into at least two heating chambers 121. A plurality of copper foil racks 110 are correspondingly provided inside one heating chamber 121. The copper foil rack 110 has a roller member, and the center of the copper foil roll 210 can be sleeved on the roller member, so that the copper foil rack 110 can be used to support the copper foil roll 210. At least one heating component 130 is correspondingly provided for one heating chamber 121. Combining Figure 2 , the heating component 130 includes a blower 220 and a heating element 230. The air outlet of the blower 220 is communicated with the air inlet hole 241 on the heating chamber 121. The heating element 230 is arranged between the air outlet of the blower 220 and the air inlet hole 241. After the air blown out by the blower 220 is heated by the heating element 230, it then enters the corresponding heating chamber 121, thereby realizing the heating of the heating chamber 121. The hot air directly enters the heating chamber, avoiding the mixing of cold air, making the temperature inside the heating chamber 121 more uniform and reducing energy consumption.

[0034] Specifically, in the present application, at least one partition 120 divides the inner cavity of the oven main body 100 into at least two independent heating chambers 121. At least one set of heating components 130 is correspondingly provided for each heating chamber 121. After the air blown out by the blower 220 is heated by the heating element 230, it enters the corresponding heating chamber 121. The copper foil roll 210 is fixed inside the corresponding heating chamber 121 through the copper foil rack 110. The staff selects the heating chamber 121 with the corresponding number of copper foil racks 110 according to the number of copper foils to be heated, and only turns on the corresponding heating component 130 to realize the independent heating of a single heating chamber 121, so that the oven space can be reasonably divided, the hot air can heat the heating chamber 121 more evenly, improve the heat utilization rate, and reduce energy waste. At the same time, an air inlet hole 241 for the hot air to enter the heating chamber 121 and an air outlet hole 242 for the hot air to discharge from the heating chamber 121 are provided inside the heating chamber 121. The air inlet hole 241 and the air outlet hole 242 are respectively arranged on the upper and lower sides of the copper foil rack 110. The hot air flows from bottom to top, making the heat transfer in the heating chamber 121 more uniform. Cooperating with the partition of the heating chamber 121, it can avoid local overheating in the heating chamber 121, further making the copper foil roll 210 heated evenly and reducing bad phenomena such as warping of the copper foil roll 210.

[0035] In some embodiments, one heating chamber 121 may correspond to two or even more heating components 130. The number of air inlet holes 241 on the heating chamber 121 is provided in multiple corresponding to the number of the air blowers 220, increasing the channels for hot air to enter the heating chamber 121, making the temperature rise in the heating chamber 121 more uniform, and achieving uniform heating of each copper foil roll 210. Among them, the multiple air inlet holes 241 can be arranged at intervals along the arrangement direction of the copper foil rollers, further realizing uniform heating of each copper foil roll 210. In addition, the multiple air inlet holes 241 can also be arranged along the extension direction of the copper foil rollers, or randomly arranged at positions lower than the copper foil rollers. In some other embodiments, one heating chamber 121 may also be correspondingly provided with one heating component 130, and hot air is sent into the heating chamber 121 through a single motor.

[0036] Combined with Figure 1 and Figure 2 , Figure 1 is a top view of the interior of the oven main body 100. Figure 2 is a side view of the interior of the oven main body 100. In this embodiment, at least two heating chambers 121 are distributed horizontally. There are multiple copper foil racks 110, and the multiple copper foil racks 110 are arranged at intervals along the distribution direction of the heating chambers 121. The partition 120 can be arranged between any two adjacent copper foil racks 110. Specifically, the heating chambers 121 inside the oven main body 100 are distributed horizontally, and at the same time, the copper foil racks 110 are also arranged along the distribution direction of the heating chambers 121, which can facilitate the division and transformation of the heating chambers 121 through the partition 120 on the basis of the original oven main body 100, and can also facilitate the placement of the copper foil racks 110. In addition, the heating chambers 121 can also be distributed in an up-and-down stacked manner, or the heating chambers 121 are distributed both horizontally and vertically.

[0037] In this embodiment, multiple copper foil racks 110 are provided in one heating chamber 121, which can improve the baking efficiency of the copper foil rolls 210. Moreover, the multiple copper foil racks 110 are arranged side by side at intervals along the distribution direction of the heating chamber 121, and the extension direction of the copper foil racks 110 is perpendicular to the distribution direction of the multiple copper foil racks 110, which is convenient for placing the copper foil racks 110, reduces space occupation, and is convenient for loading and unloading the copper foil rolls 210. In addition, the extension direction of the copper foil racks 110 can be parallel to the distribution direction of the heating chamber 121. In addition, the copper foil racks 110 can also be arranged side by side at intervals along the direction perpendicular to the distribution of the heating chamber 121. This embodiment does not specifically limit the placement of the copper foil racks 110.

[0038] Furthermore, the oven body 100 includes an outer shell 200, which encloses an inner cavity of the oven body 100. The partition 120 is arranged on the outer shell 200 and vertically divides the inner cavity of the oven body 100. A first thermal insulation layer is embedded in the outer shell 200, which can provide thermal insulation for the entire inner cavity of the oven body 100 and reduce heat loss.

[0039] In addition, a second heat-insulating layer is embedded inside the separator 120 to reduce the heat exchange between two adjacent heating chambers 121, improve the heat insulation effect of the individual heating chamber 121, and reduce the heat loss of the heating chamber 121 that is baking the copper foil roll 210. The separator 120 can be fixed between any two adjacent copper foil rolls 210 by welding, or can be connected to the oven body 100 by a detachable structure such as screws, clamps, slides, and buckles, so that the separator 120 can be detachably connected to the oven body 100. The user can change the position of the separator 120 according to the number of copper foil rolls 210 to be heated, and then adjust the number of copper foil racks 110 in the heating chamber 121, thereby improving applicability. The outer shell 200 and the separator 120 can both be made of stainless steel, and the air outlet 242 is provided on the outer shell 200.

[0040] Reference Figure 1 The heating component 130 in this embodiment also includes a return air duct 270, a first end of the return air duct 270 is connected to the air outlet, and a second end of the return air duct 270 is connected to the air inlet of the fan 220. A hot air circulation is formed between the air outlet of the fan 220, the heating chamber 121, the return air duct 270 and the air inlet of the fan 220, thereby reducing heat loss and improving energy utilization.

[0041] Further, at least one pipe fitting 250 is provided in the heating chamber 121, and the pipe fitting 250 is connected to the air outlet of the fan 220 of the corresponding heating assembly 130, and a plurality of air inlet holes 241 are provided at intervals on the pipe fitting 250, and the copper foil rack 110 is directly opposite to the position between the adjacent air inlet holes 241 on the pipe fitting 250, so that the pipe wall position between the adjacent air inlet holes 241 on the pipe fitting 250 can shield the copper foil rack 110 from wind. Specifically, the copper foil rack 110 is directly opposite to the position between the adjacent air inlet holes 241 on the pipe fitting 250, so that the air outlet direction of the air inlet holes 241 is staggered with the position of the copper foil rack 110, so as to avoid hot air from blowing directly on the copper foil roll 210, and prevent the copper foil roll 210 from being locally overheated.

[0042] Reference Figure 2 The pipe 250 extends along the length direction of the copper foil frame 110, and a plurality of air inlet holes 241 are provided on the pipe 250. Figure 3As shown, a plurality of air inlet hole groups 410 are arranged on the pipe fitting 250 at intervals along the extension direction of the pipe fitting 250, each air inlet hole group 410 includes a first air inlet hole 411 and a second air inlet hole 412 separated by a preset arc length, and a portion between the first air inlet hole 411 and the second air inlet hole 412 on the pipe fitting 250 is located directly below the copper foil rack 110, and the first air inlet hole 411 and the second air inlet hole 412 are arranged toward both sides of the copper foil rack 110. Specifically, multiple air inlet hole groups 410 are arranged at intervals along the extension direction of the pipe 250, so that the distribution direction of the air inlet hole groups 410 is consistent with the length direction of the copper foil roll 210, thereby increasing the range of the copper foil roll 210 affected by the hot air, and further making the copper foil roll 210 heated evenly, and the same air inlet hole group 410 includes a first air inlet hole 411 and a second air inlet hole 412, so that two rows of multiple first air inlet holes 411 and multiple second air inlet holes 412 are provided on the pipe 250, and the first air inlet holes 411 and the second air inlet holes 412 are arranged at intervals along the arc length direction of the pipe 250, so that the first air inlet holes 411 and the second air inlet holes 412 can face the two sides of the copper foil rack 110 respectively, and the hot air passing through the first air inlet holes 411 and the second air inlet holes 412 can naturally flow upward from the two sides of the copper foil rack 110, avoiding the hot air from directly blowing the copper foil roll 210.

[0043] In fact, the interval between the first air inlet hole 411 and the second air inlet hole 412 can be set according to the diameter of the copper foil roll 210 and the distance between the first air inlet hole 411 and the second air inlet hole 412. In this embodiment, the area between the first air inlet hole 411 and the second air inlet hole 412 is the top surface of the tube wall of the tube 250, the top surface of the tube 250 faces upward and directly faces the copper foil rack 110, the first air inlet hole 411 and the second air inlet hole 412 are arranged on both sides of the top surface of the tube 250, and the opening direction of the first air inlet hole 411 and the second air inlet hole 412 is arranged obliquely upward, which can better guide the direction of the hot air flow, and at the same time, the hotter air flow has a tendency to flow upward, which can reduce the turbulence in the heating chamber 121. The cross section of the tube 250 can be circular, square, etc., and the first air inlet hole 411 and the second air inlet hole 412 can be arranged perpendicular to the tube wall of the tube 250, or arranged at an acute angle to the tube wall of the tube 250. In addition, the first air inlet hole 411 and the second air inlet hole 412 may also be disposed on two opposite sides of the tube 250 in the horizontal direction.

[0044] Reference Figure 4, there are multiple copper foil racks 110 in a heating chamber 121. The positions and quantities of the pipe fittings 250 correspond one by one to those of the copper foil racks 110. Hot air heats the corresponding copper foil racks 110 through the air inlet holes 241 on each pipe fitting 250. In addition, when there is one copper foil rack 110 in a heating chamber 121, correspondingly, only one pipe fitting 250 can be provided below the position corresponding to the copper foil rack 110. In fact, the number of pipe fittings 250 in a single heating chamber 121 can also be greater than the number of copper foil racks 110, which can quickly heat the heating chamber 121.

[0045] In some other embodiments, the pipe fitting 250 can extend along the arrangement direction of multiple copper foil racks 110. A plurality of air inlet holes 241 are arranged in a single row on the pipe fitting 250. Every two air inlet holes 241 form an air inlet hole group 410. The two air inlet holes 241 in an air inlet hole group 410 are arranged at intervals along the extension direction of the pipe fitting 250. The part of the pipe fitting 250 between the two air inlet holes 241 in the same air inlet hole group 410 is located directly below a copper foil rack 110. The two air inlet holes 241 corresponding to the same air inlet hole group 410 face the two side edges of the copper foil rack 110. The distance between adjacent two air inlet hole groups 410 corresponds to the distance between two adjacent copper foil racks 110 arranged side by side. Among them, the air outlet direction of the air inlet hole 241 can be vertically upward, or obliquely upward and outward towards the side edge of the copper foil rack 110. Under the premise of this structure of the pipe fitting 250, one pipe fitting 250 can heat two or even more copper foils simultaneously. In actual installation, two or even more pipe fittings 250 can be arranged at intervals side by side along the length direction of the copper foil rack 110, making the heating of the copper foil roll 210 more uniform.

[0046] Refer to Figure 5 , in some specific embodiments, there are at least two pipe fittings 250 arranged at intervals in the heating chamber 121. The position of the copper foil rack 110 is higher than the two pipe fittings 250, and the copper foil rack 110 corresponds to the interval position between the two pipe fittings 250. Among them, the pipe fitting 250 is communicated with the air outlet of the blower 220 of the corresponding heating component 130, and one or more air inlet holes 241 are provided on the pipe fitting 250.

[0047] Specifically, the position where two adjacent pipe fittings 250 are spaced apart faces the copper foil holder 110 upward. The pipe fittings 250 extend along the extension direction of the copper foil holder 110. The air inlet holes 241 are provided on the pipe fittings 250, and hot air is delivered to the side of the copper foil holder 110 through the air inlet holes 241. When there are two or more copper foil holders 110, three pipe fittings 250 can be provided, so that hot air is delivered to the side of the copper foil holder 110 and between adjacent copper foil holders 110 through the air inlet holes 241, avoiding the hot air blowing directly on the copper foil roll 210 and improving the uniformity of heat reception of the copper foil roll 210. In fact, when there are multiple copper foil holders 110 in a heating chamber 121, the number of pipe fittings 250 can be increased by one based on the number of copper foil holders 110, so that the copper foil holders 110 can be correspondingly distributed between any two adjacent pipe fittings 250, improving the uniformity of heating of each copper foil roll 210.

[0048] Referring to Figure 6 , on the basis of Figure 5 , a plurality of air inlet holes 241 can be provided on the pipe fittings 250. The plurality of air inlet holes 241 are spaced apart along the extension direction of the pipe fittings 250, and the openings of the air inlets can face upward. In fact, the openings of the air inlet holes 241 can also be arranged obliquely upward as long as the hot air does not blow directly on the copper foil roll 210 when passing through the air inlet holes 241 into the heating chamber 121.

[0049] Furthermore, the heating assemblies 130 and the heating chambers 121 are arranged in one-to-one correspondence. At least two pipe fittings 250 are provided side by side in a heating chamber 121. Corresponding to the same heating chamber 121, the air outlet of the blower 220 is connected to one end of all the pipe fittings 250.

[0050] Specifically, the air outlet of the blower 220 is connected to one end of all the pipe fittings 250 in the corresponding same heating chamber 121, so that the blower 220 blows hot air to be split on at least two pipe fittings 250, so that the hot air is dispersed and blown out in the heating chamber 121, further improving the uniformity of temperature rise in the heating chamber 121, reducing the number of motors, reducing production costs, and moreover, multiple heating chambers 121 can achieve independent heating control, avoiding the problem of uneven temperature caused by the large internal space of the oven main body 100. In addition, it can also be that one heating chamber 121 corresponds to two or more heating assemblies 130. A plurality of pipe fittings 250 are provided in the heating chamber 121, and the air outlet of the blower 220 of each heating assembly 130 is connected to one end of at least two pipe fittings 250.

[0051] In this embodiment, a first temperature detection member 260 is provided in the lumen of the pipe fitting 250. Specifically, it can accurately detect the outlet temperature of the hot air, facilitating the staff to adjust the temperature of the heating member 230 according to the heating requirement of the copper foil roll 210.

[0052] Further, the first temperature detector 260 is disposed at one end of the pipe fitting 250 close to the air outlet of the blower 220. The air inlet hole 241 is disposed on the other side of the pipe fitting 250 where the first temperature detector 260 is provided, so that the hot air is detected by the first temperature detector 260 first and then shunted, improving the detection accuracy.

[0053] In addition, the copper foil processing device further includes a controller 150, and the controller 150 is electrically connected to the first temperature detector and the heating element 230. Specifically, when the temperature value detected by the first temperature detector is too high or too low, the controller 150 can control the temperature of the heating element 230 to decrease or increase correspondingly, so as to maintain the temperature of the pipe fitting 250 within the first preset range.

[0054] Further, a plurality of second temperature detectors 140 are disposed around the copper foil rack 110 in the heating chamber 121. The temperature around the copper foil rack 110 can be detected by the plurality of second temperature detectors 140 distributed in the heating chamber 121. The staff can adjust the power of the blower 220 and the heating element 230 according to the temperature detected by the second temperature detectors 140, realizing precise control and adjustment of the overall temperature inside the oven, keeping the temperature in the heating chamber 121 uniform during the production process, and improving the production quality.

[0055] In this embodiment, the second temperature detectors 140 are disposed between two adjacent copper foil racks 110, between the copper foil rack 110 and the air inlet hole 241, and between the copper foil rack 110 and the air outlet hole 242. A plurality of second temperature detectors 140 are disposed in the heating chamber 121 area, making the temperature monitoring in the heating chamber 121 more accurate, facilitating feedback to the blower 220 or the heating element 230, and further controlling the air outlet of the blower 220 and the temperature of the heating element 230, further improving the temperature control accuracy in the heating chamber 121.

[0056] In this embodiment, the controller 150 is also electrically connected to the blower 220, the heating element 230, and the plurality of second temperature detectors 140.

[0057] Specifically, when the average value of the temperatures detected by all the second temperature detectors 140 is within the second preset range, the controller 150 controls the heating element 230 to maintain the preset temperature; when the average value of the temperatures detected by all the second temperature detectors 140 is less than the second preset range, the controller 150 controls the temperature of the heating element 230 to be higher than the preset temperature; when the average value of the temperatures detected by all the second temperature detectors 140 is greater than the second preset range, the controller 150 controls the temperature of the heating element 230 to be lower than the preset temperature, so that multiple second temperature detectors 140 take points for detection in the heating chamber 121. When the detected average temperature is too high or too low, the controller 150 adjusts the power of the heating tube to control the temperature balance, improving the temperature control accuracy. In addition, the controller 150 can control the heating element 230 to directly cool down from the limited maximum value to the preset temperature for normal operation after the temperature in the heating chamber 121 reaches the preset second preset range. Or, when the internal temperature of the heating chamber 121 is too high or too low, the controller 150 controls the temperature of the heating element 230 to have an inverse correlation with the temperature of the heating chamber 121.

[0058] Meanwhile, when the difference a1 between the lowest temperature and the highest temperature detected by all the second temperature detectors 140 is less than or equal to the preset difference, the controller 150 controls the blower 220 to maintain the preset air outlet wind force; when the difference a1 between the lowest temperature and the highest temperature detected by all the second temperature detectors 140 is greater than the preset difference, the controller 150 controls the air outlet wind force of the blower 220 to be higher than the preset air outlet wind force. In fact, when the difference a1 between the lowest temperature and the highest temperature of multiple second temperature detectors 140 is greater than the preset difference, it indicates that the internal temperature of the heating chamber 121 is unbalanced at this time. Correspondingly, when it is detected that the local temperature in the heating chamber 121 is unbalanced, the controller 150 controls the blower 220 to increase the power and increase the circulating air volume of the hot air to balance the temperature in the heating chamber 121. In addition, when the difference a1 between the lowest temperature and the highest temperature of multiple second temperature detectors 140 is less than or equal to the third set value, it indicates that the temperature difference between different regions inside the heating chamber 121 is small and the temperature is relatively balanced. At this time, the controller 150 controls the blower 220 to maintain the preset air outlet wind force and maintain a balanced air supply state, so that the air flow can smoothly pass through the heating element 230 and be input into the heating chamber 121. In addition, after the difference a1 between the lowest temperature and the highest temperature detected in the heating chamber 121 is greater than the preset difference, the difference a1 has a positive correlation with the air outlet wind force of the blower 220, improving the air flow control accuracy.

[0059] In fact, when starting to heat the heating chamber 121, the wind force of the blower 220 and the temperature of the heating element 230 should be adjusted to the limited maximum values, so that the heating chamber 121 can quickly heat up. Among them, restricting the maximum wind force of the blower 220 and the maximum temperature of the heating element 230 can avoid damage to the copper foil due to excessive wind speed and temperature.
