Description

Technical Field

[0001] This application belongs to the field of copper foil technology, specifically relating to a copper wire forming device. Background Technology

[0002] Copper melting is the first step in the production of electrolytic copper foil. Currently, copper sulfate solution is prepared by immersion in the copper melting tank. The main raw material for electrolytic copper is copper wire coil. Before winding, the copper wire coil generally needs to be bent into a certain arc by a bending forming equipment to facilitate subsequent winding.

[0003] To improve the melting rate, existing technologies typically use flat copper wire for winding. However, because flat copper wire is relatively thin, it is prone to breakage when bent, thus affecting subsequent winding operations. Utility Model Content

[0004] The purpose of this application is to solve the problem that in the prior art, the flat copper wire is relatively thin, and it is easy to break when the flat copper wire is bent, which will affect the subsequent winding work.

[0006] In an exemplary embodiment of this application, the extrusion assembly includes a first pressure roller and a second pressure roller, which are respectively disposed on opposite sides of the copper wire. Both the first pressure roller and the second pressure roller are provided with gear segments. The gear segments on the first pressure roller mesh with the gear segments on the second pressure roller.

[0008] In one exemplary embodiment of this application, the spraying member includes a first spray nozzle and a second spray nozzle located on opposite sides of the copper wire, and the first spray nozzle and the second spray nozzle spray a stretching liquid onto opposite surfaces of the copper wire, respectively.

[0010] In one exemplary embodiment of this application, the collecting device includes a liquid collecting funnel and a liquid storage tank. The liquid collecting funnel is located below the copper wire. In the direction from the jetting device to the collecting device, the horizontal cross-sectional dimension of the liquid collecting funnel gradually decreases, and the end of the liquid collecting funnel away from the copper wire is connected to the liquid storage tank to store the collected stretching liquid in the liquid storage tank.

[0011] In one exemplary embodiment of this application, the jetting component includes an air pump and a jetting pipe that are interconnected. The jetting pipe is disposed on one side of the copper wire and has a plurality of jetting ports. The plurality of jetting ports are arranged side by side in the direction of movement of the copper wire so as to be able to jet gas onto both the upper and lower surfaces of the copper wire.

[0012] In one exemplary embodiment of this application, the spraying component includes a spray head and a water pump. One end of the water pump is connected to the liquid storage tank, and the other end is connected to the spray head. The spray head is provided with a spray nozzle, and the spray head sprays the stretching liquid recovered in the liquid storage tank onto the surface of the copper wire through the water pump.

[0013] In one exemplary embodiment of this application, the copper wire forming apparatus further includes a flattening assembly, which is disposed on the side of the spraying component away from the extrusion assembly.

[0015] The copper wire forming apparatus of this application has at least the following beneficial effects:

[0016] The copper wire forming apparatus of this application includes a spraying component and an extrusion assembly. The extrusion assembly creates protrusions on the surface of the copper wire, so that after the copper wire is wound onto the coil, there are gaps between adjacent copper wires, increasing the contact surface area between the copper wire and sulfuric acid, thereby increasing the dissolution rate of the copper wire. In addition, before creating the protrusions on the surface of the copper wire, the spraying component sprays a stretching liquid onto the copper wire, which can relieve tensile stress, avoid copper wire breakage, and ensure the continuity of the copper wire winding onto the coil.

[0030] Figure 1 A schematic diagram of the cross-sectional structure of the copper wire forming device is shown. Figure 2 A schematic diagram of the copper wire forming device is shown.

[0031] See Figure 1 and Figure 2 As shown, this application provides a copper wire forming apparatus 100 capable of processing flat copper wire 200. This copper wire forming apparatus 100 may include a spraying component 110 and an extrusion assembly 120. The spraying component 110 sprays a stretching liquid onto the surface of the flat copper wire 200 to alleviate the tensile stress on the flat copper wire 200 by the extrusion assembly 120, thereby preventing the flat copper wire 200 from breaking during the formation of protrusions, which would affect the subsequent winding of the flat copper wire 200. The extrusion assembly 120 forms protrusions on the surface of the flat copper wire 200 sprayed with stretching liquid, so that after the flat copper wire 200 is wound, there are gaps between adjacent flat copper wires 200, increasing the contact surface area between the flat copper wire 200 and sulfuric acid, thereby increasing the dissolution rate of the flat copper wire 200.

[0032] In some embodiments of this application, the spraying component 110 is provided with a spray nozzle (not shown in the figure), which can spray stretching liquid onto the surface of the flat copper wire 200 through the spray nozzle to relieve the tensile stress of the extrusion assembly 120 on the flat copper wire 200.

[0033] It should be noted that this drawing fluid can be mineral oil-based drawing oil, emulsified drawing fluid, or other drawing fluids.

[0034] In some embodiments of this application, the extrusion assembly 120 is disposed on one side of the spray member 110, and the extrusion assembly 120 can process the flat copper wire 200 sprayed with stretching liquid, that is, the copper wire is sprayed by the spray member 110 and then extruded to effectively relieve the tensile stress generated by the extrusion assembly 120 on the flat copper wire 200.

[0035] In some embodiments of this application, see Figure 1As shown, the extrusion assembly 120 may include a first pressure roller 121 and a second pressure roller 122. The first pressure roller 121 and the second pressure roller 122 are respectively disposed on opposite sides of the flat copper wire 200, and both the first pressure roller 121 and the second pressure roller 122 are provided with gear segments 126. The gear segments 126 on the first pressure roller 121 mesh with the gear segments 126 on the second pressure roller 122. That is, the first pressure roller 121 and the second pressure roller 122 can be gear rollers. When the flat copper wire 200 passes between the first pressure roller 121 and the second pressure roller 122, the gear segments 126 on the first pressure roller 121 and the second pressure roller 122 are used to create protrusions on the upper and lower opposite sides of the flat copper wire 200, so that after the flat copper wire 200 is wound around the coil, there is a gap between adjacent flat copper wires 200, which increases the contact surface area between the flat copper wire 200 and the sulfuric acid, thereby increasing the dissolution rate of the flat copper wire 200.

[0036] It is understood that the first pressure roller 121 and the second pressure roller 122 rotate in opposite directions so that the flat copper wire 200 can move between the first pressure roller 121 and the second pressure roller 122.

[0037] Figure 3 A schematic diagram of the extrusion assembly is shown.

[0038] In some embodiments of this application, see Figure 1 and Figure 3 As shown, the extrusion assembly 120 also includes a first motor 123. The output end of the first motor 123 can be connected to one end of the first pressure roller 121. That is, when the first motor 123 rotates, the first pressure roller 121 can rotate in the same direction of rotation as the output end of the first motor 123 under the drive of the first motor 123.

[0039] Among them, see Figure 1 and Figure 3 As shown, a first gear 124 and a second gear 125 are respectively provided at the end of the first pressure roller 121 near the first motor 123 and the end of the second pressure roller 122 near the first motor 123. The first gear 124 on the first pressure roller 121 meshes with the second gear 125 on the second pressure roller 122. During the rotation of the first pressure roller 121, the first gear 124 can rotate with the first pressure roller 121, thereby driving the second gear 125 to rotate, and then driving the second pressure roller 122 to rotate. That is, the first pressure roller 121 can drive the second pressure roller 122 to rotate in the opposite direction of rotation to the first pressure roller 121 through the first gear 124 and the second gear 125, thereby driving the flat copper wire 200 located between the first pressure roller 121 and the second pressure roller 122 to move, and forming a protrusion on the flat copper wire 200.

[0040] In some embodiments of this application, the spraying component 110 may include a first spray nozzle and a second spray nozzle located on the upper and lower surfaces of the flat copper wire 200. The first spray nozzle and the second spray nozzle can spray stretching liquid onto the opposite surfaces of the flat copper wire 200, respectively, so that both opposite sides of the flat copper wire 200 are sprayed with stretching liquid. This ensures that both opposite sides of the flat copper wire 200 are covered with stretching liquid when it is processed by the first pressure roller 121 and the second pressure roller 122, thereby effectively relieving the tensile stress on the upper and lower surfaces of the flat copper wire 200, preventing the flat copper wire 200 from breaking, and ensuring the continuity of the subsequent winding of the flat copper wire 200.

[0041] Understandably, the spraying component 110 may also have two or more spray nozzles to make the stretching liquid sprayed onto the flat copper wire 200 more uniform and further alleviate the tensile stress on the flat copper wire 200.

[0042] In some embodiments of this application, see Figure 1 As shown, the copper wire forming apparatus 100 may further include a recycling component 130, which can separate the copper wire and the drawing fluid adhering to the flat copper wire 200 to ensure the purity of the flat copper wire 200. Furthermore, the recycling component 130 can also clean and recycle the drawing fluid, improving its utilization rate.

[0043] Among them, see Figure 1 As shown, the recovery component 130 is located on the side of the extrusion component 120 away from the spray component 110, that is, after the protrusion is formed on the surface of the flat copper wire 200, it enters the recovery component 130, which is used to separate the drawing fluid from the flat copper wire 200. The recovery component 130 may include an air jet component 131 and a collection component 132. The air jet component 131 is provided with an air jet port 1310, through which the air jet component 131 can release high-pressure gas to the flat copper wire 200 to clean the drawing fluid on the flat copper wire 200, thereby separating the drawing fluid from the flat copper wire 200. The collection component 132 can be located below the flat copper wire 200, so that when the air jet component 131 blows the drawing fluid away from the flat copper wire 200, the drawing fluid will fall downwards under the action of gravity, thereby effectively collecting the falling drawing fluid and reducing the waste of drawing fluid.

[0044] It is understandable that the jetting component 131 can be located on the left and right sides of the flat copper wire 200, and it can perform jetting treatment on the upper and lower surfaces of the flat copper wire 200. That is, the jetting component 131 can simultaneously clean the stretching fluid on the upper and lower surfaces of the flat copper wire 200, thereby improving work efficiency.

[0045] In some embodiments of this application, see Figure 1As shown, the collecting component 132 may include a collecting funnel 1320 and a storage tank 1321. The collecting funnel 1320 may be located below the flat copper wire 200. From the jetting element 131 to the collecting component 132, the horizontal cross-sectional dimension of the collecting funnel 1320 gradually decreases, and the dimension of the collecting funnel 1320 near the flat copper wire 200 is larger than the jetting range of the jetting element 131, so that the drawing fluid blown out by the jetting element 131 can be collected in the collecting funnel 1320, preventing the drawing fluid from scattering randomly. The end of the collecting funnel 1320 away from the flat copper wire 200 is connected to the storage tank 1321, so that the collected drawing fluid can be stored in the storage tank 1321, thereby recovering the drawing fluid and reducing waste.

[0046] In some embodiments of this application, the liquid storage tank 1321 is also provided with scale lines for observing the liquid level (not shown in the figure). When the stretching liquid in the liquid storage tank 1321 is lower than the lowest scale line, it reminds the user to add stretching liquid to the liquid storage tank.

[0047] In some embodiments of this application, see Figure 1 As shown, the jetting component 131 may include an air pump 1311 and a jetting pipe 1312 that are interconnected. The air pump 1311 is capable of generating high-pressure gas and is connected to the jetting pipe 1312 through a pipe. The jetting pipe 1312 is located on one side of the flat copper wire 200, and the jetting pipe 1312 may be provided with multiple jetting ports 1310. The multiple jetting ports 1310 are arranged side by side in the direction of movement of the flat copper wire 200, so as to gradually spray gas onto both the upper and lower surfaces of the flat copper wire 200. The multiple jetting ports 1310 can ensure the separation effect between the flat copper wire 200 and the drawing liquid, and prevent the drawing liquid from remaining on the flat copper wire 200.

[0048] In some embodiments of this application, see Figure 1 As shown, the spraying component 110 may include a spray head 111 and a water pump 112. One end of the water pump 112 can be connected to the liquid storage tank 1321, and the other end can be connected to the spray head 111. The spray head 111 is provided with two spray nozzles, and the spray head 111 sprays the drawing liquid recovered in the liquid storage tank 1321 onto the surface of the flat copper wire 200 through the water pump 112. In this way, the drawing liquid in the liquid storage tank 1321 can be continuously used to treat the flat copper wire 200 and relieve tensile stress.

[0049] That is, the stretching fluid can be sustainably utilized through the spray component 110 and the recovery component 130, thereby improving the continuous utilization rate of the stretching fluid.

[0050] In some embodiments of this application, see Figure 1As shown, the copper wire forming apparatus 100 may further include a flattening assembly 140. The flattening assembly 140 is located on the side of the spraying member 110 away from the extrusion assembly 120, so as to pre-flatten the flat copper wire 200 before forming protrusions on the flat copper wire 200, ensuring that the bending angle of the flat copper wire 200 is the same at all points. This ensures that the protrusions opened by the first pressure roller 121 and the second pressure roller 122 on the surface of the flat copper wire 200 are of the same shape, thereby ensuring the copper melting efficiency.

[0051] Figure 4 A schematic diagram of the flattening assembly is shown.

[0052] Among them, see Figure 4 As shown, the flattening assembly 140 may include a first flattening roller 141, a second flattening roller 142, and a second motor 143. The output end of the second motor 143 can be connected to one end of the first flattening roller 141, that is, when the second motor 143 rotates, the first flattening roller 141 can rotate in the same direction of rotation as the output end of the second motor 143 under the drive of the second motor 143. A third gear 144 and a fourth gear 145 are respectively provided at the end of the first flattening roller 141 near the second motor 143 and the end of the second flattening roller 142 near the second motor 143. The third gear 144 and the fourth gear 145 on the first flattening roller 141 mesh with each other. During the rotation of the first flattening roller 141, the third gear 144 can rotate with the first flattening roller 141, thereby driving the fourth gear 145 to rotate, and then driving the second flattening roller 142 to rotate. That is, the first flattening roller 141 can drive the second flattening roller 142 to rotate in the opposite direction to the first flattening roller 141 through the third gear 144 and the fourth gear 145, so as to flatten the flat copper wire 200.

[0053] In some embodiments of this application, see Figure 1 and Figure 2 As shown, the copper wire forming apparatus 100 may further include a housing 150, a feeding roller 160, and a receiving roller 170. The feeding roller 160 and the receiving roller 170 may both be mounted on the housing 150, and are located on opposite sides of the extrusion assembly 120. The feeding roller 160 and the receiving roller 170 can drive the flat copper wire 200 to move from the feeding roller 160 to the receiving roller 170. The flattening assembly 140, the spraying component 110, the extrusion assembly 120, and the recycling assembly 130 may all be housed within the housing 150. Driven by the feeding roller 160 and the receiving roller 170, the flat copper wire 200 sequentially passes through the flattening assembly 140, the spraying component 110, the extrusion assembly 120, and the recycling assembly 130, thereby creating protrusions on opposite sides of the flat copper wire 200.

[0054] Understandably, housing the flattening component 140, spray component 110, extrusion component 120, and recycling component 130 within the housing 150 not only improves the safety of the copper wire forming apparatus 100 but also prevents the stretching fluid from splashing out during recycling. Furthermore, it effectively enhances the protection of the flattening component 140, spray component 110, extrusion component 120, and recycling component 130, preventing damage.

[0055] Furthermore, the outer edge of the collecting funnel 1320 can abut against the inner wall of the outer shell 150, thus preventing the drawing fluid from splashing out and avoiding waste of the drawing fluid. The collecting funnel 1320 can be integrally formed with the outer shell 150 or formed separately from it.

[0056] In some embodiments of this application, the outer casing 150 may also be provided with an installation port (not shown in the figure) for avoiding the liquid storage tank 1321. The liquid storage tank 1321 can be installed below the liquid collection funnel 1320 through the installation port to facilitate the collection of stretching liquid.

[0057] In some embodiments of this application, see Figure 2 As shown, the housing 150 may also be provided with an air inlet 151, through which the air pump 1311 can take in air, so that the air pump 1311 can release gas to the jet pipe 1312.

[0058] In some embodiments of this application, the housing 150 is also provided with a material inlet (not shown in the figure) and a material outlet (not shown in the figure) for the flat copper wire 200 to enter and exit, so that the flat copper wire 200 can enter the housing 150 through the material inlet to perform the working process of flattening, spraying stretching liquid, forming protrusions, and separating the stretching liquid from the flat copper wire 200. After a series of processes, it is taken out through the material outlet.

[0059] In some embodiments of this application, see Figure 2 As shown, the housing 150 is also provided with an inspection port (not shown in the figure) for inspecting and recovering the assembly 130, the stretching assembly, the spraying component 110 and the flattening assembly 140, and an inspection cover 152 for covering the inspection port. The inspection cover 152 can rotate relative to the housing 150 to open and close the inspection port, thereby inspecting the components inside the housing 150.

[0060] In some embodiments of this application, the copper wire forming apparatus 100 may further include a controller, which may be electrically connected to the first motor 123, the second motor 143, the feeding roller 160, the receiving roller 170, the air pump 1311, the water pump 112, etc., so as to automatically control the start and stop of the first motor 123, the second motor 143, the feeding roller 160, the receiving roller 170, the air pump 1311, and the water pump 112, thereby improving the automation of the copper wire forming apparatus 100.

[0061] Among them, see Figure 2 As shown, the copper wire forming device 100 may also include a display screen 180 and a control button 190. The display screen 180 and the control button 190 may both be electrically connected to the controller. The working status of the recycling component 130, the stretching component, the spraying component 110 and the flattening component 140 can be adjusted in real time through the control button 190. The working status of each component can be displayed in real time through the display screen 180, or the environmental factors such as temperature and humidity inside the housing 150 can also be displayed.

[0062] The working principle of this application is as follows: In use, flat copper wire 200 is released through the feeding roller 160, and flattened by the flattening assembly 140. The spray head 111 sprays the stretching liquid in the storage tank onto the two opposite surfaces of the flat copper wire 200 through the water pump 112 to relieve the tensile stress of the flat copper wire 200. Then, the flat copper wire 200 enters the extrusion assembly 120, and the first pressure roller 121 and the second pressure roller 122 form protrusions on the upper and lower surfaces of the flat copper wire 200. Then, the air pump 1311 releases gas to the flat copper wire 200 through the air nozzle 1310 on the air pipe 1312 to separate the flat copper wire 200 from the stretching liquid. The separated stretching liquid is collected in the liquid collection funnel 1320 and then flows back to the liquid storage tank 1321.
