Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of green foil, in particular to a cathode roller edge processing device and a green foil system. BACKGROUND

[0002] In the production process of electrolytic copper foil, the cathode roller as a core component, its surface state has a decisive influence on product quality and production efficiency. Copper ions in the electrolyte migrate directionally under the action of an electric field and undergo reduction reaction on the surface of the cathode roller, gradually depositing to form copper foil. The surface flatness of the cathode roller directly affects the uniformity and stability of the electrochemical deposition process. Maintaining the ideal surface state of the cathode roller is not only related to the surface finish, thickness uniformity and other quality indicators of the copper foil, but also is a key factor to ensure production continuity and improve the yield of finished products.

[0003] At present, in the production process of ultra-thin lithium battery copper foil, irregular oxidation marks are prone to occur on the edge of the cathode roller, which affects the production quality of the copper foil.

[0004] The prior art usually uses a scrubbing cloth soaked in a rinsing liquid to manually polish the edge of the cathode roller for polishing treatment of the edge of the cathode roller; however, due to the different operation methods and experience of the operator each time, it is difficult to ensure the consistency of the operation force of the scrubbing cloth on all parts of the edge of the cathode roller during the polishing treatment of the edge of the cathode roller, resulting in uneven polishing of the edge of the cathode roller, which makes it difficult to ensure the consistency of the polishing of the edge of the cathode roller and affects the production quality of the copper foil. CONTENT OF THE INVENTION

[0005] Therefore, the present application provides a cathode roller edge processing device to ensure the consistency of the polishing of the edge of the cathode roller and improve the production quality of the copper foil.

[0006] In addition, the present application also provides a green foil system comprising the above-mentioned cathode roller edge processing device.

[0007] In order to achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0008] A cathode roller edge processing device, comprising:

[0009] a processing portion, which is parallel to and abuts against the edge of the cathode roller in the axial direction of the cathode roller, and is used for polishing the edge of the cathode roller in cooperation with the rotation of the cathode roller in a wet state;

[0010] a liquid delivery assembly for delivering a rinsing liquid to the processing portion, the liquid delivery assembly being fixedly arranged relative to the cathode roller, and comprising a first liquid delivery pipeline for providing the rinsing liquid to the processing portion;

[0011] The liquid suction sleeve is sleeved on the first liquid supply pipe and covers the liquid outlet of the first liquid supply pipe to be filled with the flushing liquid, the processing part is covered outside the liquid suction sleeve to be soaked by absorbing the flushing liquid seeping from the liquid suction sleeve, the liquid suction property of the liquid suction sleeve is stronger than that of the processing part, and when the processing part is in parallel abutment with the edge part of the cathode roller, the liquid suction sleeve is deformed by force to extrude the flushing liquid.

[0012] The cathode roller edge part processing device provided in the application can fix the position of the processing part relative to the cathode roller in the process of polishing the edge part of the cathode roller, and the processing part is indirectly arranged on the liquid supply assembly, so that the position of the processing part relative to the cathode roller is fixed. In this way, when the processing part is in parallel abutment with the edge part of the cathode roller along the axial direction of the cathode roller and cooperates with the rotation of the cathode roller, the consistency of the pressure applied by the processing part to all parts of the edge part of the cathode roller can be ensured.

[0013] In this way, the consistency of polishing the edge part of the cathode roller can be ensured, and the production quality of the copper foil is improved.

[0014] Furthermore, since the liquid suction property of the liquid suction sleeve is stronger than that of the processing part, the absorption speed of the flushing liquid in the liquid suction sleeve is faster than that in the processing part, so that the liquid suction sleeve is filled with the flushing liquid first, and then the processing part is soaked by absorbing the flushing liquid seeping from the liquid suction sleeve. Since the seepage area of the flushing liquid from the entire circumferential direction of the liquid suction sleeve is larger than the size of the liquid outlet of the first liquid supply pipe, the flow speed of the flushing liquid seeping from the liquid suction sleeve to the processing part is slow, the uniformity of the soaking of the processing part as a whole can be ensured, the processing quality of the edge part of the cathode roller is improved, and the flushing liquid is prevented from overflowing and dripping onto the edge part of the cathode roller, which may otherwise cause watermarks on the edge part of the copper foil and affect the production yield of the copper foil.

[0015] Optionally, in the cathode roller edge part processing device, the liquid suction sleeve is detachably sleeved on the first liquid supply pipe, the first liquid supply pipe is provided with a first limiting structure and a second limiting structure, the first limiting structure axially limits the first end of the liquid suction sleeve, and the second limiting structure axially limits the second end of the liquid suction sleeve and is detachably connected with the first liquid supply pipe.

[0016] The first end and the second end of the liquid suction sleeve are two ends of the liquid suction sleeve, and the second end of the liquid suction sleeve is close to the end of the first liquid supply pipe for dismounting the liquid suction sleeve.

[0017] The detachable connection is to realize the replacement of the liquid suction sleeve. The first limiting structure and the second limiting structure provided on the first liquid supply pipe axially limit the two ends of the liquid suction sleeve, so that the displacement of the processing part along the first liquid supply pipe during operation can be avoided.

[0018] Thus, the service life of the cathode roller edge treatment device is improved, and the stability of the liquid suction sleeve after being installed to the first liquid conveying pipeline is improved, and the working reliability of the treatment part is improved.

[0019] Optionally, in the cathode roller edge treatment device, the liquid conveying assembly comprises a liquid storage tank for storing the flushing liquid, and the first liquid conveying pipeline is located below the liquid storage tank; and a second liquid conveying pipeline is connected to the bottom of the liquid storage tank at one end and connected to the first liquid conveying pipeline at the other end. The second liquid conveying pipeline is vertically arranged in the stand column, and the second liquid conveying pipeline is a flexible pipe.

[0020] Thus, the liquid storage tank is located above the first liquid conveying pipeline and the second liquid conveying pipeline, so that the flushing liquid can flow under the action of its own gravity, avoiding the setting of a power mechanism and saving the cost.

[0021] Optionally, in the cathode roller edge treatment device, a support is further arranged to be fixed relative to the cathode roller, and the first liquid conveying pipeline is arranged on the support; and an adjusting assembly for adjusting the horizontal movement and vertical movement of the first liquid conveying pipeline is arranged on the support.

[0022] The adjusting assembly is arranged so that the treatment part can move horizontally and vertically relative to the cathode roller edge under the driving of the first liquid conveying pipeline, so that the cathode roller edge treatment device can be applied to cathode rollers with different widths and can be applied to cathode rollers at different heights, improving the universality and practicality of the adjusting assembly.

[0023] The first liquid conveying pipeline is arranged in the support. The adjusting assembly can be a cooperation mechanism of a sliding rail and a pulley. For example, the support is provided with a mounting hole having vertical and horizontal extension amounts, and the inner wall of the mounting hole is provided with a rectangular protruding portion arranged oppositely, the rectangular protruding portion is distributed at intervals in the vertical direction, a sliding rail in the horizontal direction is arranged on the protruding portion, and a pulley is arranged on the outer peripheral wall of the first liquid conveying pipeline, wherein the adjacent protruding portions in the vertical direction can clamp the first liquid conveying pipeline.

[0024] Thus, the vertical adjustment of the first liquid conveying pipeline can be realized by extending the first liquid conveying pipeline into different adjacent protruding portions, and the horizontal movement of the first liquid conveying pipeline can be realized by sliding the pulley arranged on the first liquid conveying pipeline along the sliding rail.

[0025] Optionally, in the cathode roller edge treatment device, the side wall of the first liquid conveying pipeline is provided with a recessed portion; and the adjusting assembly comprises a mounting hole arranged on the support, the mounting hole has an extension amount in the vertical direction, or the mounting hole is a plurality of mounting holes arranged in the vertical direction, and the first liquid conveying pipeline can be fixed in the mounting hole in the horizontal direction.

[0026] Thus, by fitting the recess of the first infusion pipeline with the mounting hole at different positions along the vertical direction or with the mounting hole at different positions along the vertical direction, vertical adjustment and fixation of the first infusion pipeline are realized.

[0027] Optionally, the adjusting assembly further comprises a clamping assembly, which comprises two clamping members movably arranged on both sides of the mounting hole along the vertical direction, and the two clamping members respectively extend into the mounting hole and can press or limit the recess to prevent the first infusion pipeline from being raised at the position of the processing portion.

[0028] Optionally, the clamping member comprises a bolt and a nut. A plurality of nuts are arranged on the inner wall of the column provided with the mounting hole, and the plurality of nuts are distributed along the vertical direction. The bolt is provided with two, and the bolt is sequentially arranged through the mounting hole and the oppositely arranged nut at different heights and simultaneously presses the recess, so as to realize the vertical adjustment and fixation of the first infusion pipeline, prevent the processing portion from being raised due to the reaction force of the cathode roller edge portion during polishing, and improve the working reliability.

[0029] The components of the adjusting assembly are common structures on the market, which are easy to obtain and have low cost. When the clamping member is damaged, it can be replaced individually, which is convenient and improves the practicality of the adjusting assembly.

[0030] Optionally, in the cathode roller edge portion processing device, the recesses are a plurality of recesses and are distributed along the axial direction of the first infusion pipeline; and the first infusion pipeline is movably arranged in the mounting hole along the axial direction so that different recesses correspond to the clamping assembly. During work, the first infusion pipeline is arranged horizontally.

[0031] In this way, the horizontal movement of the first infusion pipeline can be realized, so that it can be adapted to cathode rollers of various width specifications, and the versatility of the cathode roller edge portion processing device is improved.

[0032] Optionally, in the cathode roller edge portion processing device, the support comprises a support base arranged below the infusion assembly, the support base comprises a clamping portion capable of being clamped on a foil production machine, and the adjusting assembly is arranged on a column. The support base comprises clamping portions oppositely arranged, and the clamping portions can be vertical rods or rectangular structures or special-shaped structures. The column is vertically arranged and provided with a mounting hole.

[0033] In this way, the occupied space of the cathode roller edge portion processing device is saved, the compactness of the cathode roller edge portion processing device is improved, and the cathode roller edge portion processing device is convenient to carry, install and disassemble.

[0034] Optionally, in the cathode roller edge treatment device, the liquid outlet of the first liquid conveying pipeline is multiple, and is arranged on the circumferential side wall of the first liquid conveying pipeline and is uniformly distributed along the axial direction or the circumferential direction of the first liquid conveying pipeline.

[0035] In this way, the liquid supply uniformity of the liquid outlet to the liquid suction sleeve is good, the uniformity of the overall liquid suction speed of the liquid suction sleeve is improved, and the liquid permeation uniformity of the entire circumferential direction of the liquid suction sleeve is improved, thereby improving the circumferential wetting uniformity of the treatment part and ensuring the uniformity of the treatment part to the cathode roller edge.

[0036] The treatment part is a layer of Scotch-Brite cloth.

[0037] The liquid suction sleeve is a sponge sleeve.

[0038] In this way, the sponge sleeve is filled with the washing liquid and then permeates the liquid to the Scotch-Brite cloth layer, thereby wetting the Scotch-Brite cloth layer. The sponge sleeve has good liquid suction and can permeate liquid outward after being filled with liquid, thereby improving the circumferential wetting uniformity of the Scotch-Brite cloth layer. The Scotch-Brite cloth layer is convenient to control the polishing thickness and has good precision.

[0039] Optionally, in the cathode roller edge treatment device, a flow control assembly is further included, and the flow control assembly is used to control the flow speed of the washing liquid of the liquid conveying assembly.

[0047] The application provides a cathode roller edge part processing device, which can ensure the consistency of polishing of the cathode roller edge part, and thus improves the production quality of copper foil. In addition, the application also provides a green foil system comprising the cathode roller edge part processing device.

[0048] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0049] As shown in Figure 1 The application provides a cathode roller edge part processing device, which comprises a processing part 1, an infusion assembly 2 and a liquid suction sleeve 3. The processing part 1 is parallel to the cathode roller edge part along the cathode roller shaft and abuts against the cathode roller edge part, and is used for polishing the cathode roller edge part in cooperation with the rotation of the cathode roller in a wet state. The infusion assembly 2 is used for conveying flushing liquid to the processing part 1, and the infusion assembly 2 is fixedly arranged relative to the cathode roller. The infusion assembly 2 comprises a first infusion pipeline 21 used for providing flushing liquid to the processing part 1. The first infusion pipeline 21 is provided with a liquid outlet 211 on the peripheral wall. The liquid suction sleeve 3 is sleeved on the first infusion pipeline 21 and covers the liquid outlet 211 of the first infusion pipeline 21 to be full of flushing liquid. The processing part 1 is covered outside the liquid suction sleeve 3 to be wet by absorbing the flushing liquid leaked from the liquid suction sleeve 3. The liquid suction property of the liquid suction sleeve 3 is stronger than that of the processing part 1. When the processing part 1 abuts against the cathode roller edge part in parallel, the liquid suction sleeve 3 is deformed under stress to squeeze out flushing liquid. Thus, it can be seen that the liquid suction sleeve 3 is located between the liquid outlet 211 of the first infusion pipeline 21 and the processing part 1.

[0050] The cathode roller edge processing device provided by the embodiment of the present application is used as follows: first, the first liquid delivery pipe 21 of the liquid delivery assembly 2 is used to provide the flushing liquid; at this time, the liquid suction sleeve 3 first absorbs the flushing liquid from the liquid outlet 211 of the first liquid delivery pipe 21, and after the liquid suction sleeve 3 is filled with the flushing liquid, the flushing liquid is exuded from the liquid suction sleeve 3 to the processing part 1, and the processing part 1 is wetted by absorbing the flushing liquid exuded from the liquid suction sleeve 3; then, the liquid delivery assembly 2 is fixedly arranged relative to the cathode roller, and the processing part 1 is kept in parallel abutment with the cathode roller edge along the axial direction of the cathode roller at the same time, and at this time, the processing part 1 exerts pressure on the cathode roller edge; then, the wetted processing part 1 is matched with the rotation of the cathode roller to polish the cathode roller edge, and in the processing process, as the flushing liquid in the processing part 1 is exuded to the cathode roller edge, the interaction force between the processing part 1 and the cathode roller edge drives the liquid suction sleeve 3 to deform under stress and the flushing liquid exuded from the liquid suction sleeve 3 continuously enters the processing part 1, and at the same time, the liquid outlet 211 of the first liquid delivery pipe 21 continuously supplies the liquid suction sleeve 3 with the flushing liquid, so as to ensure the continuity of the polishing and flushing.

[0051] In summary, in the process of polishing the cathode roller edge, the liquid delivery assembly 2 is fixedly arranged relative to the cathode roller, and the processing part 1 is indirectly arranged on the liquid delivery assembly 2, so that the position of the processing part 1 relative to the cathode roller is fixed; in this way, when the processing part 1 is in parallel abutment with the cathode roller edge along the axial direction of the cathode roller and is matched with the rotation of the cathode roller, the cathode roller edge is polished, and at the same time, the consistency of the pressure exerted by the processing part 1 on all parts of the cathode roller edge is ensured, so as to ensure the consistency of the polishing of the cathode roller edge, and thus the production quality of the copper foil is improved.

[0052] When the processing part 1 is in parallel abutment with the cathode roller edge along the axial direction of the cathode roller and is matched with the rotation of the cathode roller, the processing part 1 can be fixed or can rotate; preferably, the processing part 1 is fixedly arranged on the first liquid delivery pipe 21 through the liquid suction sleeve 3, and the processing part 1 is fixed when the cathode roller rotates, so that the structure is relatively simple.

[0053] Furthermore, because the liquid suction property of the liquid suction sleeve 3 is stronger than that of the processing part 1, the absorption speed of the flushing liquid in the liquid suction sleeve 3 is faster than that in the processing part 1, so that after the liquid suction sleeve 3 is filled with the flushing liquid, the entire circumferential direction of the processing part 1 is wetted by absorbing the flushing liquid exuded from the liquid suction sleeve 3, and because the exuding area of the flushing liquid exuded from the entire circumferential direction of the liquid suction sleeve 3 is larger than the size of the liquid outlet 211 of the first liquid delivery pipe 21, the flowing speed of the flushing liquid exuded from the liquid suction sleeve 3 to the processing part 1 is relatively slow, so as to ensure the uniformity of the wetting of the entire processing part 1, improve the processing quality of the cathode roller edge, and at the same time, avoid the flushing liquid from overflowing and dropping to the cathode roller edge, so as to avoid the existence of water marks on the edge of the copper foil, and thus affect the production yield of the copper foil.

[0054] It should be noted that "treatment section 1 covering the outside of the absorbent sleeve 3" means that treatment section 1 covers the entire outer surface of the absorbent sleeve 3, or covers the entire outer circumferential surface of the absorbent sleeve 3. In this case, treatment section 1 can be aligned with the axial position of the absorbent sleeve 3, or it can protrude from the axial position of the absorbent sleeve 3, to prevent the rinsing fluid seeping from the absorbent sleeve 3 from flowing to a position outside treatment section 1. Preferably, the second end of treatment section 1 (e.g. Figure 1 The right end of the processing section 1 shown (which abuts parallel to the edge of the cathode roller during operation) is aligned axially with the second end of the suction sleeve 3, ensuring that the entire working part of the processing section 1 is supported by the suction sleeve 3, thus guaranteeing uniform force distribution on the working surface of the processing section 1; the first end of the processing section 1 (as shown) Figure 1 The left end of the processing section 1 shown in the figure is suspended when the processing section 1 is working and does not come into contact with the edge of the cathode roller. It protrudes from the first end of the liquid suction sleeve 3 at the axial position, thereby forming a liquid receiving edge to prevent the flushing liquid seeping out of the liquid suction sleeve 3 from flowing to a position outside the processing section 1.

[0055] Liquid absorption refers to the material's ability to absorb rinsing liquid, including absorption speed and absorption volume. The treatment section 1 is hollow cylindrical in shape, and the liquid absorption sleeve 3 is also hollow cylindrical in shape. Preferably, in this application, the liquid outlet 211 is located on the side wall of the first infusion pipe 21 that contacts the treatment section 1, or the liquid outlet 211 is located on the end face of the first infusion pipe 21 that contacts the treatment section 1.

[0056] The flushing fluid flows out from the outlet 211 of the first infusion pipe 21. Since the absorbent sleeve 3 has a greater absorbency than the processing unit 1, the absorbent sleeve 3 can absorb and retain part of the flushing fluid. After the absorbent sleeve 3 is filled with the flushing fluid, the flushing fluid slowly permeates into the processing unit 1 through the absorbent sleeve 3.

[0057] In this way, on the one hand, the rinsing liquid of the processing unit 1 is prevented from dripping, thereby avoiding the formation of watermarks on the edge of the cathode roller and improving the production yield of copper foil; on the other hand, the liquid seepage of the processing unit 1 is made uniform, which can better rinse the edge of the cathode roller and improve the polishing effect.

[0058] Specifically, the rinsing fluid can be a liquid mixed with an anti-oxidation medium or water; the processing unit 1 is a hollow cylindrical shape and is made of absorbent material, which has the ability to absorb and retain the rinsing fluid, thereby realizing the grinding process on the edge of the cathode roller. In this embodiment, the processing unit 1 and the first infusion pipe 21 of the infusion assembly 2 are coaxially arranged. When grinding the edge of the cathode roller, the first infusion pipe 21 is in a horizontal state so that the processing unit 1 and the edge of the cathode roller are in parallel contact and have a certain pressure between them, so that the force on the processing unit 1 is uniform.

[0059] Further, the liquid suction sleeve 3 is detachably sleeved on the first liquid conveying pipeline 21, so that the processing part 1 outside the liquid suction sleeve 3 is detachably connected with the liquid conveying assembly 2. In this way, the processing part 1 is replaced according to the use effect, and the service life of the cathode roll edge processing device is improved.

[0060] It should be noted that when the cathode roll edge is polished, the polishing surface of the processing part is used to polish the cathode roll edge. The polishing surface can be formed of friction material.

[0061] Due to the force acting on the processing part 1 during work, displacement of the processing part 1 relative to the first liquid conveying pipeline 21 may occur. The first liquid conveying pipeline 21 of the embodiment is provided with a first limiting structure 6 and a second limiting structure 7. The first limiting structure 6 axially limits the first end of the liquid suction sleeve 3, and the second limiting structure 7 axially limits the second end of the liquid suction sleeve 3 and is detachably connected with the first liquid conveying pipeline 21. The first end and the second end of the liquid suction sleeve 3 are two ends of the liquid suction sleeve 3, and the second end of the liquid suction sleeve 3 is close to the end of the first liquid conveying pipeline 21 for dismounting the liquid suction sleeve 3.

[0062] The first limiting structure 6 and the second limiting structure 7 provided on the first liquid conveying pipeline 21 axially limit the two ends of the liquid suction sleeve 3, so that displacement of the processing part 1 along the first liquid conveying pipeline 21 during work can be avoided.

[0063] In this way, the stability of the liquid suction sleeve 3 after being installed on the first liquid conveying pipeline 21 is improved, and the working reliability of the processing part 1 is also improved.

[0064] When the processing part 1 needs to be replaced, the liquid suction sleeve 3 also needs to be dismounted. Specifically, first, the second limiting structure 7 is dismounted from the first liquid conveying pipeline 21, then the liquid suction sleeve 3 with the processing part 1 is axially slid away from the end of the first liquid conveying pipeline 21 for dismounting the liquid suction sleeve 3, then a new processing part 1 is replaced or the liquid suction sleeve 3 is replaced together, the liquid suction sleeve 3 with the processing part 1 is sleeved into the end of the first liquid conveying pipeline 21 for dismounting the liquid suction sleeve 3 and slid to a position abutting against the first limiting structure 6, and finally the second limiting structure 7 is reinstalled on the first liquid conveying pipeline 21.

[0065] In order to facilitate dismounting, the second limiting structure 7 is connected with the first liquid conveying pipeline 21 through threads. Specifically, the first liquid conveying pipeline 21 is provided with external threads, and the second limiting structure 7 is a nut. The nut can be screwed to realize dismounting, which is simple to operate.

[0066] The first limiting structure 6 can be a nut, and the first liquid conveying pipeline 21 is provided with matching external threads. The first limiting structure 6 can also be an annular protrusion formed on the outer wall of the first liquid conveying pipeline 21 or other forms capable of serving as a limiting structure.

[0067] It should be noted that the second limiting structure 7 and the first infusion pipeline 21 can also adopt other detachable connection modes, such as buckle connection.

[0068] In some optional embodiments, the processing part 1 is also detachably arranged outside the liquid suction sleeve 3. When the processing capability of the processing part 1 is reduced after long-time use, the processing part 1 can be replaced alone, which is faster and saves cost.

[0069] In some optional embodiments, the infusion assembly 2 comprises a liquid storage tank 22 for storing the flushing liquid, and the first infusion pipeline 21 is located below the liquid storage tank 22; the second infusion pipeline 23 is connected to the bottom of the liquid storage tank 22 at one end and connected to the first infusion pipeline 21 at the other end.

[0070] In some optional embodiments, the liquid storage tank 22 is provided with a liquid inlet hole, the second infusion pipeline 23 is arranged in a stand 42, the stand 42 is preferably made of metal, the second infusion pipeline 23 is a flexible pipe, the end of the second infusion pipeline 23 is flexibly connected or plugged with the first infusion pipeline 21, and when the flushing liquid is input into the liquid storage tank 22, it is conveyed to the first infusion pipeline 21 from the second infusion pipeline 23 under the action of gravity and wets the processing part 1, wherein the cross-sectional shape of the liquid storage tank 22 is not limited to be rectangular, circular or irregular.

[0071] By flowing under its own gravity, the setting of the power mechanism is avoided, and cost is saved. In some optional embodiments, the cathode roller processing device further comprises a bracket 4 fixedly arranged relative to the cathode roller, and the first infusion pipeline 21 is arranged on the bracket 4; the bracket 4 is provided with an adjusting assembly for adjusting the horizontal movement and vertical movement of the first infusion pipeline 21.

[0072] The bracket 4 fixedly arranged relative to the cathode roller provides fixed support for the first infusion pipeline 21 according to the embodiments of the application, the fixed arrangement of the infusion assembly 2 relative to the cathode roller is realized, and thus the position of the processing part 1 relative to the cathode roller is fixed when the processing part works.

[0073] Optionally, the adjusting assembly can be a cooperation mechanism of a sliding rail and a pulley. For example, the bracket 4 is provided with a mounting hole having vertical and horizontal extension amounts, the inner wall of the mounting hole is oppositely provided with rectangular protruding parts which are spaced apart in the vertical direction, the protruding parts are provided with a sliding rail in the horizontal direction, and the pulley is arranged on the outer peripheral wall of the first infusion pipeline 21, wherein the adjacent protruding parts in the vertical direction can clamp the first infusion pipeline 21. In this way, the vertical adjustment of the first infusion pipeline 21 can be realized by extending the first infusion pipeline 21 into different adjacent protruding parts, and the horizontal movement of the first infusion pipeline 21 can be realized by sliding the pulley arranged on the first infusion pipeline 21 along the sliding rail.

[0074] It should be noted that the pulley arranged on the outer peripheral wall of the first infusion pipeline 21 has a brake member to control the running and stopping of the pulley.

[0075] It should be noted that the arrangement direction of the sliding rail is parallel to the arrangement direction of the cathode roller.

[0076] The adjustment assembly is arranged so that the processing portion 1 can move horizontally and vertically along the cathode roller edge portion under the driving of the first infusion pipeline 21, so that the cathode roller edge portion processing device can be applied to cathode rollers with different widths and at different heights, improving the versatility and practicality of the adjustment assembly.

[0077] In the present application, the side wall of the first infusion pipeline 21 is provided with a recess; the adjustment assembly comprises a mounting hole arranged on the support 4, the mounting hole has an extension in the vertical direction or the mounting hole is a plurality of mounting holes arranged in the vertical direction, and the first infusion pipeline 21 can be fixed in the mounting hole in the horizontal direction. In this embodiment, the vertical adjustment and fixation of the first infusion pipeline 21 are achieved by mounting the recess of the first infusion pipeline 21 with different parts of the mounting hole in the vertical direction or with mounting holes at different positions in the vertical direction.

[0078] The fixation of the first infusion pipeline 21 in the horizontal direction relative to the mounting hole can be achieved by counterweighting the first infusion pipeline 21 itself in the horizontal direction to overlap the cathode roller edge portion, or by other structures.

[0079] In order to improve the fixation strength of the first infusion pipeline 21, the adjustment assembly further comprises a clamping assembly 5 comprising two clamping members movably arranged on both sides of the mounting hole in the vertical direction, the two clamping members respectively extend into the mounting hole and can press or limit the recess to prevent the position of the first infusion pipeline 21 provided with the processing portion 1 from being raised. The support 4 comprises a column 42 described later, the column 42 is a hollow structure, the mounting hole is arranged on the side wall of the column 42 and has an extension in the vertical direction, a plurality of nuts are arranged on the inner wall of the column 42 where the mounting hole is arranged, the plurality of nuts are distributed in the vertical direction, two bolts are arranged, the two bolts are sequentially arranged through the mounting hole and the oppositely arranged nuts at different heights and simultaneously press the recess, so as to achieve the vertical adjustment and fixation of the first infusion pipeline 21, prevent the position of the processing portion 1 from being raised due to the reaction force of the cathode roller edge portion during the grinding process, and improve the working reliability. Alternatively, the clamping member can also limit the upward rotation of one end of the first infusion pipeline 21 installed with the processing portion 1 by a circumferential limiting structure such as a limiting protrusion, to prevent the position of the processing portion 1 from being raised.

[0080] The adjusting assembly component is a common structure on the market, easy to obtain, low cost, and when the clamping piece is damaged, it can be replaced individually, convenient to replace, and improve the practicability of the adjusting assembly.

[0081] In addition, when the treatment part 1 is disassembled, the bolt is pressed in the recess, at this time, slightly rotating the bolt can reduce the pressing force of the bolt on the recess, manually pressing the end of the first liquid pipeline 21 away from the treatment part 1, and lifting the treatment part 1, so as to facilitate the replacement of the treatment part 1, and avoid the interference between the treatment part 1 and other parts.

[0082] Among them, the recess is multiple, and is distributed along the axial direction of the first liquid pipeline 21; the first liquid pipeline 21 is movably arranged in the mounting hole in the axial direction to correspond to different recesses. In operation, the first liquid pipeline 21 is horizontally arranged in the mounting hole, and extends into different recesses through the clamping assembly 5 to realize horizontal movement of the first liquid pipeline 21.

[0083] In this way, the horizontal movement of the first liquid pipeline 21 is realized, which can adapt to cathode rollers of various width specifications, improving the versatility of the cathode roller edge treatment device.

[0084] Further, the support 4 comprises: a support 41 arranged below the liquid supply assembly 2, the support 41 comprising clamping portions 411 capable of being clamped on the foil production machine; and a column 42 on which the adjusting assembly is arranged. The support 41 comprises clamping portions, and the clamping portions comprise oppositely arranged clamping portions 411, which can be vertical rods or rectangular structures, special-shaped structures or two oppositely arranged flat plates. Generally, the clamping portions 411 are clamped on the acid mist prevention side cover plate arranged near the edge of the cathode roller. The column 42 is vertically arranged and provided with the mounting hole, and the first liquid pipeline 21 is arranged in the column 42 in the horizontal direction.

[0085] In this way, the occupied space of the cathode roller edge treatment device is saved, the compactness of the cathode roller edge treatment device is improved, and the carrying, installation and disassembly of the cathode roller edge treatment device are facilitated.

[0086] Preferably, the liquid outlets 211 of the first liquid pipeline 21 are multiple, arranged on the circumferential side wall of the first liquid pipeline 21 and uniformly distributed along the axial direction or the circumferential direction of the first liquid pipeline 21. In this way, the liquid supply uniformity of the liquid outlets 211 to the liquid suction sleeve 3 is good, the uniformity of the overall liquid suction speed of the liquid suction sleeve 3 is improved, the liquid permeation uniformity of the entire circumferential direction of the liquid suction sleeve 3 is improved, the circumferential wetting uniformity of the treatment part 1 is improved, and the polishing uniformity of the treatment part 1 on the edge of the cathode roller is ensured.

[0087] In the specific embodiment, the treatment part 1 is a layer of scouring pad, and the liquid suction sleeve 3 is a sponge sleeve.

[0088] The sponge sleeve is soaked with the washing liquid, and then the sponge sleeve permeates the washing liquid to the layer of the scrubbing cloth, so as to wet the layer of the scrubbing cloth. The sponge sleeve has good liquid absorption, and can permeate the washing liquid outward after being fully soaked with the washing liquid, thereby improving the uniformity of the circumferential wetting of the layer of the scrubbing cloth.

[0089] Specifically, when the edge of the cathode roller is polished, the layer of the scrubbing cloth soaked with the washing liquid (for example, water) is used to polish the whole circumference of the edge of the cathode roller. The layer of the scrubbing cloth is convenient to control the polishing thickness and has good precision.

[0090] It can be understood that the processing part 1 and the liquid absorption sleeve 3 can also adopt other materials, for example, the processing part 1 adopts a non-woven fabric with a large mesh number, and the liquid absorption sleeve 3 adopts a sponge cloth with a small mesh number, as long as the uniformity of the liquid absorption of the processing part 1 can be achieved.

[0091] Further, the support 41 and the column 42 are detachably connected.

[0092] For example, the support 41 is provided with a plug-in hole, the plug-in hole is matched with the column 42, and the detachable connection between the support 41 and the column 42 is realized by inserting or pulling out the column 42 in the plug-in hole; or the top surface of the support 41 is protrusively provided with an L-shaped clamping piece, the vertical part of the clamping piece is connected with the top surface of the support 41, the horizontal part of the clamping piece is spaced apart from and arranged in parallel with the top surface of the support 41, and the bottom of the column 42 is provided with a plug-in piece, the distance between the clamping piece and the top surface is matched with the thickness of the plug-in piece, and the detachable connection between the support 41 and the column 42 is realized by inserting or pulling out the plug-in piece into or out of the space formed by the clamping piece and the top surface.

[0093] In this way, the support 41 can be separately carried with the infusion assembly 2 and the adjusting assembly, thereby improving the convenience and flexibility of carrying.

[0094] In some optional embodiments, a flow control assembly is further included, and the flow control assembly is used to control the flow speed of the washing liquid of the infusion assembly 2. In the present application, the flow control assembly is arranged on the column 42, the flow control assembly is manually controlled or electrically controlled, and the flow control assembly includes a display screen for observing the flow speed.

[0095] In this way, when the flow of the washing liquid is large, the phenomenon that the washing liquid drops from the processing part 1 to generate water marks on the edge of the cathode roller is avoided, and the production yield of the copper foil is improved.

[0096] In addition, the application also provides a green foil system, which comprises a cathode roller and a cathode roller edge processing device for polishing the edge of the cathode roller, and the cathode roller edge processing device is the cathode roller edge processing device as described above.
