Description

Technical Field

[0001] This application relates to the field of thin strip processing technology, and in particular to a thin strip electrolytic processing apparatus and a thin strip electrolytic processing method. Background Technology

[0002] Metal strips (typically less than or equal to 0.1 mm in thickness, and sometimes even at the micrometer or nanometer level) are widely used in numerous high-end manufacturing fields due to their excellent physical, mechanical, and functional properties. In the electronics industry, strips can be used to manufacture high-performance flexible electronic devices and ultra-thin displays. Their lightweight and high flexibility meet the stringent material requirements of modern electronic products. In the aerospace field, the demand for strips is constantly growing. Especially in the manufacture of micro-sensors and lightweight structural components, their high strength and low density characteristics are fully utilized. In the new energy field, strips are widely used in high-efficiency energy storage devices, such as thin-film batteries and supercapacitors, thereby improving energy density and charge / discharge efficiency.

[0003] In existing technologies, electrolytic machining is suitable for processing thin strips. This method can achieve high-precision machining without direct contact with the thin strip, overcoming the shortcomings of mechanical machining methods, while also avoiding the heat-affected zone in thin strip laser machining and EDM. Furthermore, when processing thin strips, this method not only maintains high processing efficiency, but the recycling of the electrolyte also reduces environmental impact, aligning with the needs of modern green manufacturing.

[0004] Currently, electrolyte is typically sprayed at high speed onto the thin strip using a nozzle. However, the scouring effect of the electrolyte can deform the thin strip, leading to poor surface quality and insufficient processing consistency in the final product. Summary of the Invention

[0005] The purpose of this application is to provide a thin strip electrolytic processing apparatus and a thin strip electrolytic processing method to reduce the probability of thin strip deformation and improve the surface quality and processing consistency of the final thin strip.

[0006] To achieve the above objectives, in a first aspect, this application provides a thin-strip electrolytic processing apparatus. The apparatus includes a conductive element, a carrier element, a first connecting structure, a second connecting structure, an electrolyte tank, and a power source. The thin-strip material is wrapped and fastened to the outer wall of the carrier element. Along the height direction of the first connecting structure, both ends of the conductive element are connected to the first connecting structure. Along the height direction of the second connecting structure, one end face of the carrier element is connected to the second connecting structure, which is used to drive the carrier element to rotate. The electrolyte tank contains electrolyte, and the thin-strip material and at least a portion of the conductive element are located in the electrolyte, with the conductive elements facing each other and spaced apart from the thin-strip material. The negative terminal of the power source is used for electrical connection with the conductive element, and the positive terminal of the power source is used for electrical connection with the thin-strip material.

[0007] In one implementation, the conductive element is a linear conductive element; The one-dimensional dimension of the cross-section of the conductive component ranges from 0.03 mm to 0.20 mm; The conductive components are made of at least one or more of brass, molybdenum, or tungsten.

[0008] In one implementation, the entire strip material is located in the electrolyte, and the projection of the strip material onto the conductive component is entirely located within the area of ​​the conductive component immersed in the electrolyte. The centerline of the support component is parallel to the centerline of the conductive component, and the extension direction of the centerline of the support component and the extension direction of the centerline of the conductive component are consistent with the height direction of the electrolyte tank.

[0009] In one implementation, the second connecting structure is used to drive the carrier to rotate about the center line of the carrier in a first direction or in a second direction, wherein the first direction and the second direction are opposite. The first connection structure includes: Along the height direction of the first connecting structure, there are a first clamping member and a second clamping member that are opposite to each other and spaced apart; the second clamping member is located inside the electrolyte tank; The first rotary drive component is rotatably connected to the first clamping component; The first connector is fixedly connected to the connecting rod connected to the first rotary drive component; the second clamping component is disposed on the first connector; the two ends of the conductive component are respectively connected to the first clamping component and the second clamping component; the first rotary drive component is used to drive the conductive component to rotate.

[0010] In one implementation, the thin strip electrolytic processing apparatus further includes: a telescopic structure; the telescopic structure is disposed on the first connecting structure and is used to drive the conductive element to move toward or away from the thin strip material; and / or, the telescopic structure is disposed on the second connecting structure and is used to drive the thin strip material and the carrier to move toward or away from the conductive element. An outlet is provided at the bottom of the electrolyte tank, and an inlet is provided on the side of the electrolyte tank. The thin strip electrolytic processing apparatus also includes: an electrolyte circulation device; the electrolyte circulation device is connected to the inlet through a first pipe to provide electrolyte to the electrolyte tank; the electrolyte circulation device is connected to the outlet through a second pipe.

[0011] In one implementation, a groove penetrating the support member is provided on the outer side wall of the support member along the height direction; Along the length of the thin strip material, the thin strip material sequentially includes a first part, a second part, and a third part; the second part covers the outer side wall of the carrier except for the groove, and the first part and the third part are both located in the groove. The thin strip electrolytic processing apparatus also includes: An electrical connector is located within a groove and fits into the first and third parts; the electrical connector is electrically connected to the positive terminal of the power supply. The fastening clamp is located in the groove and is fastened to the electrical connector, the thin strip material and the carrier by a locking element.

[0012] In one implementation, the carrier is a non-conductive carrier, and the material of the carrier includes at least one or more of ceramic, quartz, or glass; The materials of the electrical connectors include at least one or more of stainless steel, pure copper, or copper-tungsten alloy; The fastening clamp is made of at least one or more of epoxy resin, rubber, or plastic; The power supply is a pulse power supply.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: In the thin strip electrolytic processing apparatus provided in this application, the thin strip material is tightly wrapped and fixed to the outer wall of the carrier. This ensures that the thin strip material is thinned in the electrolyte and maintains a stable position during the rotation of the carrier, preventing the thin strip material from loosening or shifting. Furthermore, while ensuring that the rotation speed of the carrier (or the rotation speed of the thin strip material) is consistent with that in this application and the prior art, compared to the prior art where the electrolyte is sprayed at high speed from a nozzle to scour the thin strip material, in this application, the thin strip material and at least some conductive elements are located in the electrolyte—that is, the thin strip material and at least some conductive elements are immersed in the electrolyte. The flow rate of the electrolyte in this application is lower than that in the prior art; therefore, the scouring effect of the electrolyte flow on the surface of the thin strip material is small or negligible. Based on this, the probability of thin strip material deformation is reduced, and the surface quality and processing consistency of the final thin strip material are improved. Furthermore, since the second connecting structure is used to drive the carrier to rotate, and the thin strip material is tightly wrapped and fixed to the outer wall of the carrier, the second connecting structure can simultaneously drive the carrier and the thin strip material to rotate. Due to the rotation of the carrier and the thin strip material, the electrolyte creates a disturbance effect within the processing zone. This disturbance not only accelerates the discharge rate of electrolytic reaction products in the processing zone but also ensures timely replenishment of the electrolyte in the processing zone within the electrolyte tank. In actual thinning of the thin strip material, since the negative terminal of the power supply is used to electrically connect with the conductive element, and the positive terminal is used to electrically connect with the thin strip material, the conductive element acts as the cathode, and the thin strip material as the anode. Moreover, the thin strip material and at least part of the conductive element are located in the electrolyte. Through an electrochemical reaction, the surface of the thin strip material is removed until a thin strip material of a predetermined thickness is obtained.

[0014] Secondly, this application also provides a thin strip electrolytic processing method, which uses the thin strip electrolytic processing apparatus described in the above technical solution.

[0015] The thin strip electrolytic processing method includes: The thin strip material to be processed is wrapped and fastened to the outer wall of the carrier; The carrier and the thin strip material to be processed are placed in an electrolyte tank containing electrolyte; Connect the negative terminal of the power supply to the conductive component, connect the positive terminal of the power supply to the thin strip material, and then start the power supply. The second connecting structure is activated, causing it to rotate the carrier component around its centerline; the distance between the conductive component and the thin strip material to be processed is the processing distance. After thinning at least a portion of the strip material to be processed to a preset thickness, the power is turned off, and the finally obtained strip material is removed from the carrier.

[0016] The beneficial effects of the thin strip electrolytic processing method provided in this application are the same as those of the thin strip electrolytic processing apparatus described in the above technical solutions, and will not be repeated here.

[0017] In one implementation, activating the second connecting structure to cause the carrier to rotate about the centerline of the carrier includes: When the bearing rotates for the first time, the first rotation includes a pulse width interval and a pulse interval in sequence. All subsequent rotations of the carrier component sequentially include one inter-pulse interval, one pulse width interval, and one additional inter-pulse interval. The distance between the conductive element and the processed thin strip material is adjusted to the processing pitch within the inter-pulse interval during the first rotation and within the additional inter-pulse interval during all subsequent rotations. Within the pulse width interval, the conductive element is used to thin the second part; within the inter-pulse interval, the conductive element passes through the first and third parts, and the thin strip material stops thinning; the carrier element rotates alternately in clockwise and counterclockwise directions; the rotation angle of the carrier element within the pulse width interval is... The rotation angle of the bearing component within the pulse interval is , .

[0018] In one implementation, the thickness of the thin strip material to be processed is The preset thickness is The thickness of the thin strip material decreases by the amount of rotation of the bearing component. ; ; It is an integer; This indicates the total number of rotation cycles of the load-bearing component; one rotation cycle of the load-bearing component includes one clockwise rotation and one counterclockwise rotation. After removing the final strip material from the support, the strip electrolytic processing method also includes: Remove the first and third portions of the final obtained strip material to obtain the target strip material.

Detailed Implementation

[0022] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. For example, the first threshold and the second threshold are only used to distinguish different thresholds and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0023] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0024] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a combination of a and b, a combination of a and c, a combination of b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0025] Referring to the background section, the thickness range of thin strips has different standards in different industries. For example, in the non-ferrous metal processing industry, copper and aluminum strips with a thickness of less than 0.1 mm and a relatively narrow width are generally called thin strips, while those with even thinner thicknesses are called ultra-thin strips or super-thin strips. In the production of silicon steel, products with a thickness of 0.03 mm to 0.35 mm are all called ultra-thin silicon steel strips.

[0026] Currently, thin strip processing methods include machining, chemical etching, and laser processing. Traditional machining methods are prone to deformation and damage when processing thin strips, making it difficult to achieve high precision. Furthermore, while chemical etching technology is widely used, its efficiency is low and it poses certain environmental pollution risks. Laser processing, as a non-contact processing method, can achieve high precision, but when processing thin strips, the heat-affected zone may cause a decrease in material properties.

[0027] To avoid the aforementioned problems, electrolytic machining is currently commonly used to prepare thin strips. This method achieves high-precision machining without direct contact with the thin strip, compensating for the shortcomings of mechanical machining methods, while also avoiding the heat-affected zone in thin strip laser machining and EDM. Furthermore, this method not only maintains high processing efficiency during thin strip machining, but the recycling of the electrolyte also reduces environmental impact, aligning with the needs of modern green manufacturing.

[0028] However, electrolytic processing in the existing technology has the following problems: First: Currently, the electrolyte is usually sprayed at high speed onto the thin strip using a nozzle. However, the high-speed spraying of electrolyte can cause the thin strip to deform, which can easily lead to poor surface quality and insufficient processing consistency of the final thin strip.

[0029] Second: Due to the presence of stray corrosion, it is difficult to simultaneously meet the requirements of high-end applications in terms of machining accuracy and efficiency.

[0030] Third: When processing thin strips, uneven distribution of electrolyte flow may occur, which further increases the uncertainty in the processing.

[0031] To address at least one of the aforementioned technical problems, in a first aspect, this application provides a thin-strip electrolytic processing apparatus. See also... Figure 1 The thin-strip electrolytic processing apparatus includes a conductive element 1, a carrier element 2, a first connecting structure 3, a second connecting structure 4, an electrolyte tank 5, and a power supply 6. The thin-strip material 7 is wrapped and secured to the outer wall of the carrier element 2. Along the height direction A of the first connecting structure 3, both ends of the conductive element 1 are connected to the first connecting structure 3. Along the height direction B of the second connecting structure 4, one end face of the carrier element 2 is connected to the second connecting structure 4, which is used to drive the carrier element 2 to rotate. The electrolyte tank 5 contains an electrolyte 50, and the thin-strip material 7 and at least a portion of the conductive element 1 are located in the electrolyte 50, with the conductive elements 1 facing each other and spaced apart from the thin-strip material 7. The negative terminal of the power supply 6 is used for electrical connection with the conductive element 1, and the positive terminal of the power supply 6 is used for electrical connection with the thin-strip material 7.

[0032] It should be noted that the width of the thin strip material 7 is not specified here. For example, the thin strip material 7 can be a wide thin strip material or a narrow thin strip material. For example, the width of the wide thin strip material is greater than or equal to 200 mm, and the width of the narrow thin strip material is less than 200 mm.

[0033] Compared with the prior art, the beneficial effects of this application are as follows: See Figure 1In the thin strip electrolytic processing apparatus provided in this application, the thin strip material 7 is tightly wrapped and fixed to the outer wall of the support member 2. This ensures that the thin strip material 7 is thinned in the electrolyte 50 and maintains a stable position during the rotation of the support member 2, preventing the thin strip material 7 from loosening or shifting. Furthermore, while ensuring that the rotation speed of the support member 2 (or the rotation speed of the thin strip material 7) is consistent with that in this application and the prior art, compared to the prior art where the electrolyte 50 is sprayed at high speed from the nozzle to scour the thin strip material 7, in this application, both the thin strip material 7 and at least a portion of the conductive element 1 are located in the electrolyte 50; that is, the thin strip material 7 and at least a portion of the conductive element 1 are immersed in the electrolyte 50. The flow rate of the electrolyte 50 in this application is lower than that in the prior art; therefore, the scouring effect of the electrolyte 50 flow on the surface of the thin strip material 7 is very small or negligible. Based on this, the probability of deformation of the thin strip material 7 is reduced, improving the surface quality and processing consistency of the final thin strip material 7. Furthermore, since the second connecting structure 4 is used to drive the rotation of the carrier 2, and the thin strip material 7 is tightly wrapped and fixed to the outer wall of the carrier 2, the second connecting structure 4 can simultaneously drive the carrier 2 and the thin strip material 7 to rotate. Due to the rotation of the carrier 2 and the thin strip material 7, the electrolyte 50 creates a disturbance effect within the processing zone. This disturbance not only accelerates the discharge rate of electrolytic reaction products in the processing zone but also ensures timely renewal of the electrolyte 50 in the processing zone within the electrolyte tank. In the actual thinning of the thin strip material 7, since the negative terminal of the power supply 6 is used for electrical connection with the conductive element 1, and the positive terminal of the power supply 6 is used for electrical connection with the thin strip material 7, the conductive element 1 is the cathode, and the thin strip material 7 is the anode. Moreover, the thin strip material 7 and at least a portion of the conductive element 1 are located in the electrolyte 50. Through electrochemical reaction, the surface of the thin strip material 7 is removed until a thin strip material 7 of a predetermined thickness is obtained. It should be noted that the aforementioned "processing zone" can be understood as the area where the electrochemical reaction occurs, or the area where the material is removed.

[0034] As one possible implementation, see Figure 1 Power supply 6 is a pulse power supply. The voltage and current values ​​of the pulse power supply depend on the material and bandwidth of the thin strip. For example, the voltage of the pulse power supply is 0V to 40V, and the current is 0A to 1000A.

[0035] As one possible implementation, see Figure 1 and Figure 2 The conductive component 1 is a linear conductive component. Compared to block-shaped conductive components, firstly, the linear conductive component is suitable for electrolytic machining applications requiring high-precision micro-removal of thin strip material 7, achieving a more refined machining effect. Secondly, the structural characteristics of the linear conductive component effectively avoid the stray corrosion problem commonly found in the electrolytic machining of large-size thin strip material 7 by block-shaped conductive components, thereby significantly improving the machining accuracy and surface quality of large-size thin strip material 7.

[0036] In one alternative approach, see Figure 2 The one-dimensional dimension of the cross-section of conductive component 1 ranges from 0.03 mm to 0.20 mm. For example, the one-dimensional dimension can be 0.03 mm, 0.05 mm, 0.07 mm, 0.09 mm, 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, or 0.20 mm, etc. The cross-section of conductive component 1 is perpendicular to its length direction.

[0037] At this point, the conductive element 1 has an extremely small one-dimensional dimension, making it more suitable for electrolytic machining applications requiring high-precision micro-removal of thin strip material 7, thus achieving a more refined machining effect. Furthermore, it further avoids the stray corrosion problem commonly found in the electrolytic machining of large-size thin strip material 7 by blocky conductive elements, thereby significantly improving the machining accuracy and surface quality of large-size thin strip material 7.

[0038] The aforementioned one-dimensional dimension can be the length, width, diameter, major axis, minor axis, or diagonal of the cross-section of the conductive component 1. When the cross-section of the conductive component 1 is circular, the one-dimensional dimension can be the diameter of the cross-section of the conductive component 1. When the cross-section of the conductive component 1 is elliptical, the one-dimensional dimension can be the major axis or minor axis of the cross-section of the conductive component 1. When the cross-section of the conductive component 1 is square, the one-dimensional dimension can be the width of the cross-section of the conductive component 1.

[0039] In one alternative embodiment, the conductive element 1 is made of at least one or more of brass, molybdenum, or tungsten.

[0040] In some embodiments, the conductive element 1 is a linear conductive element, and the one-dimensional dimension of the cross-section of the linear conductive element ranges from 0.03 mm to 0.20 mm. The linear conductive element is a brass wire.

[0041] As one possible implementation, see Figure 1 and Figure 2 The entire strip material 7 is located in the electrolyte 50, and the projection of the strip material 7 onto the conductive element 1 is entirely within the area of ​​the conductive element 1 immersed in the electrolyte 50. For example, the length L1 of the area of ​​the conductive element 1 immersed in the electrolyte 50 is always greater than the width W of the strip material 7.

[0042] At this point, this structural design can ensure that the electrolyte 50 maintains a uniform flow distribution and stable flow rate characteristics at different processing positions of the thin strip material 7 during long-term continuous processing, thereby ensuring the consistency of the processing accuracy and surface quality of the thin strip material 7.

[0043] In some embodiments, the length of the projection of the thin strip material 7 onto the conductive element 1 is less than the length L1 of the region of the conductive element 1 immersed in the electrolyte 50. That is, the width W of the thin strip material 7 is less than the immersion length of the conductive element 1 in the electrolyte 50.

[0044] As one possible implementation, see Figure 2 The centerline of the carrier 2 is parallel to the centerline of the conductive element 1, and the extension direction of the centerline of the carrier 2 and the extension direction of the centerline of the conductive element 1 are consistent with the height direction of the electrolyte tank 5. This further ensures the consistency of the processing accuracy and surface quality of the thin strip material 7.

[0045] As one possible implementation, see Figure 1 The second connecting structure 4 is used to drive the carrier 2 to rotate around the center line of the carrier 2 in a first direction or in a second direction, the first direction and the second direction being opposite.

[0046] In the actual thinning process, the thin strip electrolytic processing apparatus of this application adopts a unique motion control scheme for the carrier 2. By periodically alternating between forward and reverse rotation, it solves the problem of stray corrosion caused by unidirectional rotation. That is, this bidirectional rotation mechanism can effectively counteract the stray corrosion generated during unidirectional rotation.

[0047] As one possible implementation, see Figure 1 and Figure 2 The first connecting structure 3 includes a first clamping member 30, a second clamping member 31, a first rotary drive component 32, and a first connecting member 33. Along the height direction A of the first connecting structure 3, the first clamping member 30 and the second clamping member 31 are opposite to each other and spaced apart. The second clamping member 31 is located within the electrolyte tank 5, and the first clamping member 30 is rotatably connected to the first rotary drive component 32. A connecting rod 34 connected to the first rotary drive component 32 is fixedly connected to the first connecting member 33. The second clamping member 31 is disposed on the first connecting member 33. Both ends of the conductive member 1 are respectively connected to the first clamping member 30 and the second clamping member 31. The first rotary drive component 32 is used to drive the conductive member 1 to rotate. For example, the second clamping member 31 is rotatably disposed on the first connecting member 33. The aforementioned first rotary drive component 32 may include a rotating shaft and a motor for driving the rotating shaft to rotate, etc.

[0048] Since the first rotary drive component 32 is used to drive the conductive component 1 to rotate, as described above, the carrier component 2 and the thin strip material 7 can also rotate. Therefore, during the actual thinning of the thin strip material 7, the rotating conductive component 1, carrier component 2, and thin strip material 7, along with the electrolyte 50, create a disturbance effect within the processing zone. This disturbance not only accelerates the discharge rate of electrolytic reaction products in the processing zone but also ensures the timely replenishment of the electrolyte 50 within the processing zone in the electrolyte tank.

[0049] In some embodiments, the rotation speed of the conductive element 1 is from 0 r / min to 1000 r / min, the rotation speed of the support element 2 is 10 r / min, and the rotation directions of the conductive element 1 and the support element 2 are opposite. The conductive element 1 and the support element 2 rotate in opposite directions at the aforementioned speeds, creating a disturbance effect in the electrolyte 50 within the processing zone. This disturbance not only accelerates the discharge rate of electrolytic reaction products from the processing zone but also ensures timely replenishment of the electrolyte 50 within the processing zone in the electrolyte tank. For example, the rotation speed of the conductive component 1 can be 0.1 r / min, 1 r / min, 10 r / min, 30 r / min, 50 r / min, 100 r / min, 150 r / min, 200 r / min, 250 r / min, 300 r / min, 350 r / min, 400 r / min, 450 r / min, 500 r / min, 550 r / min, 600 r / min, 700 r / min, 800 r / min, 900 r / min, or 1000 r / min, etc.

[0050] In one alternative approach, see Figure 1 and Figure 2 The aforementioned first connector 33 includes a first sub-connector 35 and a second sub-connector 36. One end of the first sub-connector 35 is fixedly connected to the connecting rod 34, and one side of the first sub-connector 35 is connected to one end of the second sub-connector 36. The second clamping member 31 is rotatably mounted on the second sub-connector 36. Further, the distance between the first clamping member 30 and the second clamping member 31 is equal to the length of the conductive member 1. At this time, the conductive member 1 located between the first clamping member 30 and the second clamping member 31 is in a taut state. The specific structures of the first rotary drive component 32, the first clamping member 30, the second clamping member 31, the first sub-connector 35, and the second sub-connector 36 are not specifically limited here; please refer to the prior art.

[0051] As one possible implementation, see Figure 1The second connecting structure 4 includes a second rotary drive component 40, a second connector 41, and a third connector 42. The second rotary drive component 40 is rotatably connected to the first end of the second connector 41, and the second end of the second connector 41 is connected to one end face of the carrier component 2. In this case, the second rotary drive component 40 drives the carrier component 2 to rotate via the second connector 41, thereby driving the thin strip material 7 disposed on the carrier component 2 to rotate. The third connector 42 is located on one side of the second rotary drive component 40, and the second rotary drive component 40 is connected to the carrier structure 8 via the third connector 42. The first rotary drive component 32 is connected to the carrier structure 8 via a connecting rod 34. The specific structures of the second connector 41 and the third connector 42 are not specifically limited here; reference can be made to existing technologies. The aforementioned second rotary drive component 40 may include a rotating shaft and a motor for driving the rotating shaft to rotate, etc.

[0052] As one possible implementation, see Figure 1 and Figure 2 The thin strip electrolytic processing device also includes: a telescopic structure ( Figure 1 and Figure 2 (Not shown in the image). A telescopic structure is provided on the first connecting structure 3 to drive the conductive element 1 to move closer to or away from the thin strip material 7. Alternatively, the telescopic structure is provided on the second connecting structure 4 to drive the thin strip material 7 and the carrier 2 to move closer to or away from the conductive element 1. Alternatively, the telescopic structure is provided on the first connecting structure 3 to drive the conductive element 1 to move closer to or away from the thin strip material 7, and the telescopic structure is provided on the second connecting structure 4 to drive the thin strip material 7 and the carrier 2 to move closer to or away from the conductive element 1.

[0053] Before the strip material 7 is thinned, the distance between the conductive element 1 and the initial state of the strip material 7 is the processing gap. As the strip material 7 is continuously thinned, the distance between the conductive element 1 and the thinned strip material 7 continuously changes. Since this application also includes a telescopic structure, the distance between the conductive element 1 and the strip material 7 can be adjusted using the telescopic structure, so that the distance between the conductive element 1 and the strip material 7 is always equal to the initially set processing gap, thereby ensuring the stability and quality of the processing process, as well as ensuring the consistency of the processing accuracy and surface quality of the finally obtained strip material 7.

[0054] In one alternative, the telescopic structure described above can be a cylinder or an electric push rod.

[0055] For example, when the telescopic structure is provided on the first connecting structure 3 and the telescopic structure is a cylinder, the cylinder includes a cylinder body and a piston rod. The cylinder body is connected to the fourth connecting member 80 included in the bearing structure 8. The free end of the piston rod is fixedly connected to the connecting rod 34. The piston rod is used to drive the connecting rod 34 to move towards or away from the thin strip material 7, thereby driving the conductive member 1 to move towards or away from the thin strip material 7.

[0056] When the telescopic structure is provided on the second connecting structure 4, and the telescopic structure is a cylinder, the cylinder includes a cylinder body and a piston rod. The cylinder body is connected to the fifth connecting member 81 included in the bearing structure 8. The free end of the piston rod is fixedly connected to the third connecting member 42. The piston rod is used to drive the third connecting member 42 to move closer to or away from the conductive member 1, thereby driving the thin strip material 7 and the bearing member 2 to move closer to or away from the conductive member 1.

[0057] In some embodiments, see Figure 1 The fourth connector 80 and the fifth connector 81 are opposite to each other and spaced apart. The above-mentioned supporting structure 8 also includes a base 82, on which the electrolyte tank 5, the fourth connector 80 and the fifth connector 81 are all disposed.

[0058] As one possible implementation, see Figure 1 and Figure 2 The electrolyte tank 5 has an outlet at its bottom and an inlet on its side. The thin strip electrolytic processing apparatus also includes an electrolyte circulation device 9. The electrolyte circulation device 9 is connected to the inlet via a first pipe 90 and is used to supply electrolyte 50 to the electrolyte tank 5. The electrolyte circulation device 9 is connected to the outlet via a second pipe 91, at which point the electrolytic reaction products are discharged from the electrolyte tank 5 into the electrolyte circulation device 9.

[0059] In one alternative approach, see Figure 1 The electrolyte circulation device 9 includes an electrolyte circulation tank 92 and a power structure. The power structure can be a pump, which provides power to transfer the electrolyte 50 in the electrolyte circulation tank 92 to the electrolyte tank 5 through the first pipe 90 and the inlet. The specific structure of the electrolyte circulation tank 92 is not specifically limited here; please refer to existing technology.

[0060] When actually thinning the strip material 7, the flow rate of the electrolyte 50 at the inlet and outlet is adjusted so that the strip material 7 is completely immersed in the electrolyte 50.

[0061] In some embodiments, see Figure 1A support platform 83 is provided on the base 82, and the electrolyte tank 5 is placed on the support platform 83. At this time, the bottom of the electrolyte tank 5 is higher than the through hole in the electrolyte circulation tank 92 that is connected to the second pipe 91, so that the electrolysis reaction products can be discharged from the outlet to the electrolyte circulation device 9.

[0062] Based on the preceding description, the thin strip material 7 is wrapped and fastened to the outer wall of the support member 2. The following description uses two possible implementation methods as examples. It should be noted that the following descriptions are for comprehension purposes only and are not intended to limit specific implementations.

[0063] Example 1: The aforementioned support member 2 is a regular three-dimensional structure, such as a cylinder, cuboid, or frustum. The thin strip material 7 tightly covers the outer wall of the support member 2, that is, the thin strip material 7 is tightly attached to the outer wall of the support member 2. The two ends of the thin strip material 7 are fastened to the support member 2 by adhesive, or the two ends of the thin strip material 7 are fastened to the support member 2 by bolts or other fasteners.

[0064] It should be noted that after the thinning process of the thin strip material 7 is completed, the thinned thin strip material 7 is removed from the support member 2, and the two ends of the thinned thin strip material 7 that are fastened to the support member 2 are removed. The remaining thinned thin strip material 7 is the part that is needed in the end.

[0065] Example 2: See Figure 1 , Figure 3 and Figure 4 Along the height direction of the support member 2, a groove penetrating the support member 2 is formed on the outer side wall of the support member 2. Along the length direction of the thin strip material 7, the thin strip material 7 sequentially includes a first part 70, a second part 71, and a third part 72. The second part 71 covers the outer side wall of the support member 2 except for the groove, and the first part 70 and the third part 72 are both located within the groove. For example, the first part 70 and the third part 72 are located on the outer side wall of the groove. The thin strip electrolytic processing apparatus also includes: an electrical lead connector 93 and a fastening clamp 94. The electrical lead connector 93 is located within the groove, and the electrical lead connector 93 is in contact with the first part 70 and the third part 72, and the electrical lead connector 93 is electrically connected to the positive terminal of the power supply 6. The fastening clamp 94 is located within the groove, and the fastening clamp 94 is fastened to the electrical lead connector 93, the thin strip material 7, and the support member 2 by a locking member 95.

[0066] In actual use, the current from the power supply 6 is transmitted through the lead connector 93 to the first part 70 and the third part 72 included in the thin strip material 7, and then to the entire thin strip material 7.

[0067] In some embodiments, the negative terminal of the pulse power supply is connected to a conductive brush 96 via a wire, and the conductive brush 96 contacts the conductive element 1, thereby making the conductive element 1 the cathode. The positive terminal wire of the pulse power supply is connected to the lead-in connector 93, thereby making the thin strip material 7 the anode. Further, the length of the lead-in connector 93 is greater than the height of the support element 2, in which case the lead-in connector 93 protrudes from the support element 2, facilitating the connection between the positive terminal wire of the pulse power supply and the lead-in connector 93.

[0068] In one alternative approach, see Figure 3 and Figure 4 The length of the first part 70 is equal to the length of the third part 72; for example, the length of the first part 70 can be 5 mm. The first part 70 includes a first sub-part 73 and a second sub-part 74, with the two ends of the first sub-part 73 connected to the second part 71 and the second sub-part 74, respectively. The third part 72 includes a third sub-part 75 and a fourth sub-part 76, with the two ends of the third sub-part 75 connected to the fourth sub-part 76 and the second part 71, respectively. The lengths of the first sub-part 73 and the third sub-part 75 are both L2, and the lengths of the second sub-part 74 and the fourth sub-part 76 are both L3. The first sub-part 73 and the third sub-part 75 are both fitted against the sidewalls of the groove, while the second sub-part 74 and the fourth sub-part 76 are both fitted against the bottom of the groove. The height of the sidewalls of the groove is equal to the length of the first sub-part 73, and the width of the bottom of the groove is equal to the sum of the lengths of the second sub-part 74 and the fourth sub-part 76. The free end of the first part 70 is connected to the free end of the third part 72.

[0069] The widths of both the lead-in connector 93 and the fastening clamp 94 are less than or equal to 2L3. One locking member 95 simultaneously locks the lead-in connector 93, the fastening clamp 94, and the second sub-part 74. The other locking member 95 simultaneously locks the lead-in connector 93, the fastening clamp 94, and the fourth sub-part 76. At this time, the thin strip material 7 is fastened to the carrier 2, and the thin strip material 7 forms reliable contact and connection with the carrier 2. The carrier 2 provides a stable support foundation for the subsequent electrolytic processing or treatment of the thin strip material 7. Furthermore, in this application, the thin strip material 7 is completely in contact with the outer wall of the carrier 2, and there are no wrinkles or gaps between the thin strip material 7 and the carrier 2, which is beneficial to enhancing the conductivity of the thin strip material 7. Furthermore, compared to the thin strip material 7 being connected by multiple rollers, this application uses fastening clamps 94 and locking members 95 to fasten the thin strip material 7 to the carrier 2, reducing the problem of the thin strip material 7 shifting and deforming due to the scouring of the electrolyte 50.

[0070] For example, the aforementioned support member 2 can be a cylinder, cuboid, or frustum before the groove is formed; preferably, the support member 2 is a cylinder before the groove is formed. Further, the aforementioned locking member 95 can be a bolt.

[0071] For Example 1 and Example 2, see Figure 2 The width W of the thin strip material 7 is less than or equal to the height of the bearing 2.

[0072] In one alternative, the carrier 2 is a non-conductive carrier, for example, the material of the carrier 2 includes at least one or more of ceramic, quartz or glass.

[0073] The material of the electrical connector 93 includes at least one or more of stainless steel, pure copper, or copper-tungsten alloy.

[0074] The fastening clamp 94 is made of at least one or more of epoxy resin, rubber, or plastic.

[0075] Secondly, this application also provides a thin strip electrolytic processing method, which uses the thin strip electrolytic processing apparatus described in the above technical solution.

[0076] Combination Figures 1 to 6 The thin strip electrolytic processing method includes: Step 101: Wrap the thin strip material 7 to be processed around and secure it to the outer wall of the support 2.

[0077] For example, the thin strip material 7 to be processed can be wrapped around and fastened to the outer wall of the cylindrical support member. Alternatively, referring to the description of the first aspect, the second portion 71 of the thin strip material 7 to be processed wraps around the outer wall of the support member 2, excluding the groove, with the first portion 70 and the third portion 72 both located within the groove. An electrical connector 93 and a fastening clamp 94 are located within the groove, the electrical connector 93 abutting against the first portion 70 and the third portion 72, and the electrical connector 93 being electrically connected to the positive terminal of the power supply 6. The fastening clamp 94 is fastened to the electrical connector 93, the thin strip material 7, and the support member 2 via a locking member 95.

[0078] Step 102: Place the carrier 2 and the thin strip material 7 to be processed into the electrolyte tank 5 containing the electrolyte 50.

[0079] For example, the entire strip material 7 to be processed is located in the electrolyte 50, and the projection of the strip material 7 onto the conductive element 1 is entirely within the area of ​​the conductive element 1 immersed in the electrolyte 50. Furthermore, the centerline of the carrier 2 is parallel to the centerline of the conductive element 1. It should be noted that at least a portion of the conductive element 1 is always located within the electrolyte tank 5 to ensure that at least a portion of the conductive element 1 is within the electrolyte 50. Further, the inlet and outlet of the electrolyte tank 5 are respectively connected to the electrolyte circulation tank 92, and a pump provides power to transfer the electrolyte 50 in the electrolyte circulation tank 92 to the electrolyte tank 5 through the first pipe 90 and the inlet.

[0080] Step 103: Connect the negative terminal of power supply 6 to conductive component 1, connect the positive terminal of power supply 6 to thin strip material 7, and start power supply 6.

[0081] For example, the negative terminal of the pulse power supply is connected to the conductive brush 96, which is in contact with the conductive element 1, thereby making the conductive element 1 the cathode. The positive terminal of the pulse power supply is connected to the lead-in connector 93, thereby making the thin strip material 7 the anode.

[0082] Step 104: Activate the second connecting structure 4, causing the second connecting structure 4 to drive the carrier 2 to rotate around the center line of the carrier 2. The distance between the conductive element 1 and the thin strip material 7 to be processed is the processing distance.

[0083] As one possible implementation, when the strip material 7 includes a first portion 70, a second portion 71, and a third portion 72, the processing spacing refers to the horizontal distance between the conductive element 1 and the second portion 71 included in the strip material 7 to be processed. For example, the processing spacing can be 0.1 mm.

[0084] In some embodiments, since the carrier is a three-dimensional structure, the second part covering the outer wall of the carrier includes a part close to the conductive element and a part away from the conductive element, and the distance between the side of the second part close to the conductive element and the conductive element is the processing spacing.

[0085] As one possible implementation, when the thin strip material 7 includes a first part 70, a second part 71, and a third part 72, activating the second connecting structure 4 to cause the carrier 2 to rotate around the centerline of the carrier 2 includes: See Figure 5 When the bearing 2 rotates for the first time, the first rotation includes a pulse width interval 97 and an inter-pulse interval 98 in sequence. See Figure 6 All subsequent rotations of the carrier 2 include an inter-pulse interval 98, a pulse width interval 97, and an additional inter-pulse interval 98 in sequence. Within the inter-pulse interval 98 during the first rotation and within the additional inter-pulse interval 98 during all subsequent rotations, the distance between the conductive element 1 and the processed thin strip material 7 is adjusted to the processing spacing. Within the pulse width interval 97, the conductive element 1 is used to thin the second portion 71. Within the inter-pulse interval 98, the conductive element 1 passes through the first portion 70 and the third portion 72, at which point the thin strip material 7 stops thinning. The carrier element 2 rotates alternately in clockwise and counterclockwise directions, and the rotation angle of the carrier element 2 within the pulse width interval 97 is [missing information]. The rotation angle of the bearing 2 within the inter-pulse interval 98 is , .

[0086] When the above technical solution is adopted, the distance between the conductive element 1 and the processed thin strip material 7 is adjusted by the telescopic structure within the inter-pulse interval 98 during the first rotation and within the additional inter-pulse interval 98 during all subsequent rotations. This allows for constant gap processing without affecting the processing progress, ensuring the stability and quality of the processing process, as well as ensuring the consistency of the processing accuracy and surface quality of the final thin strip material 7.

[0087] In some embodiments, the carrier 2, driven by the second rotation drive component 40 included in the second connection structure 4, rotates clockwise first and then counterclockwise, alternating in this manner.

[0088] See Figure 5 The first rotation of the carrier 2 is clockwise, and this first rotation includes a pulse width interval 97 and an inter-pulse interval 98. For ease of understanding... Figure 5 The starting point E and ending point F of the first rotation of the carrier 2 are marked. Within the pulse width interval 97, the conductive element 1 gradually thins the second part 71 as the carrier 2 rotates. The rotation angle of the carrier 2 within the pulse width interval 97 is... Within the interpulse interval 98, the conductive element 1 rotates with the carrier element 2, passing through the first portion 70 and the third portion 72, at which point the thin strip material 7 stops thinning. The rotation angle of the carrier element 2 within the interpulse interval 98 is... , After the above processing, the second portion 71 of the thin strip material 7 is thinned, and the distance between the conductive element 1 and the second portion 71 after the first thinning is increased compared to the initial distance. To ensure the stability and quality of the processing, within the inter-pulse interval 98, a telescopic structure is used to adjust the distance between the conductive element 1 and the second portion 71 after the first thinning to the processing spacing. For example, the telescopic structure moves the carrier 2 horizontally a distance closer to the conductive element 1, and this distance is equal to the thinning amount of the thin strip material 7 when rotated 360°. Since the carrier 2 rotates 360°, the starting point E and the ending point F coincide.

[0089] For example, see Figure 5 The groove on the support member 2 has a first groove edge 20 and a second groove edge 21, and the angle corresponding to the counterclockwise arc from the first groove edge 20 to the second groove edge 21 is . The angle corresponding to the clockwise arc from the edge 20 of the first groove to the edge 21 of the second groove is In this application, Greater than .

[0090] join Figure 6The carrier 2 then rotates counterclockwise for the second time. This second rotation includes an inter-pulse interval 98, a pulse width interval 97, and an additional inter-pulse interval 98. At this point, the rotation angle of the carrier 2 is 360°+. To facilitate understanding in Figure 6 The starting point P and ending point Q of the second rotation of the carrier 2 are marked. Within the first inter-pulse interval 98, the processing distance remains constant, and there is no need to activate the telescopic structure. Within the pulse width interval 97, the conductive element 1 thins the second portion 71 again. At this point, the processing distance changes, so an additional inter-pulse interval 98 is needed to adjust the distance between the conductive element 1 and the second thinned portion 71 using the telescopic structure, thus maintaining a constant processing distance. All subsequent rotations of the carrier 2 follow the same principle and will not be elaborated further here.

[0091] Before step 106, the thin strip electrolytic processing method provided in this application further includes: step 105: start the first connecting structure 3, so that the first connecting structure 3 drives the conductive element 1 to rotate around the center line of the conductive element 1.

[0092] For example, the conductive element 1 rotates clockwise or counterclockwise under the drive of the first rotation drive component 32 included in the first connection structure 3. It should be noted that the rotation directions of the conductive element 1 and the carrier element 2 are not necessarily related; their rotation directions can be set according to actual conditions. Preferably, the rotation direction of the conductive element 1 is opposite to that of the carrier element 2.

[0093] It should be noted that during the process of thinning the strip material 7, the inlet and outlet flow rates of the electrolyte circulation tank 92 need to be adjusted to ensure that the water level of the electrolyte 50 in the electrolyte tank 5 is constant, so that the strip material 7 is completely immersed in the electrolyte 50.

[0094] Step 106: After thinning at least a portion of the strip material 7 to be processed to a preset thickness, turn off the power supply 6 and remove the finally obtained strip material 7 from the carrier 2.

[0095] For example, after the thickness of the second part 71 of the strip material 7 to be processed is reduced to a preset thickness, the pulse power supply and the electrolyte circulation device 9 are turned off in sequence, and then the finally obtained strip material 7 is removed from the carrier 2.

[0096] Based on the preceding description, since the first portion 70 and the third portion 72 were not thinned, the first portion 70 and the third portion 72 included in the final obtained strip material 7 are removed to obtain the target strip material. That is, the thinned second portion 71 is the target strip material.

[0097] As one possible implementation, the thickness of the thin strip material 7 to be processed is The preset thickness is When the support component 2 rotates one revolution, the thickness of the thin strip material 7 decreases by [amount missing]. .

[0098] ; It is an integer; This indicates the total number of rotation cycles of the load-bearing component; one rotation cycle of the load-bearing component includes one clockwise rotation and one counterclockwise rotation. It is worth noting that if If the value is not an integer, the thickness reduction can be increased by increasing the processing voltage of the pulse power supply. Alternatively, the thickness reduction can be reduced by lowering the processing voltage of the pulse power supply. .

[0099] The beneficial effects of the thin strip electrolytic processing method provided in this application are the same as those of the thin strip electrolytic processing apparatus described in the above technical solutions, and will not be repeated here.

Accordingly, this specification and drawings are merely exemplary illustrations of this application as defined by the appended claims, and are considered to cover any and all modifications, variations, combinations, or equivalents within the scope of this application.
