[0030] With the continuous and vigorous development of the electronic industry, the demand and quality requirements of downstream industries such as electronic circuit boards, copper-clad boards and lithium batteries for industrial copper foil continue to rise. Not only are higher requirements placed on the physical and chemical performance indicators of the product such as tensile strength and elongation, peel strength, oxidation resistance, etc., but also the copper foil microcrystalline structure and apparent morphology are required to be more uniform and fine.

[0031] Since the surface of the cathode roller is the basis for copper foil electrodeposition, the roller surface quality directly affects the apparent quality of the copper foil light surface, and has an indirect effect on the internal grain structure and micro-morphology of the copper foil. Therefore, the polishing process is a key link in the production of copper foil. However, whether the roller surface is uniform, whether the foil is uniform, most of which can be found by winding to the physical testing room for detection, and the polishing adjustment is affected by the proficiency of personnel, and it is relatively difficult to achieve uniformity.

[0032] Generally, the staff can directly adjust the polishing brush according to the relevant work experience, but this way needs to go through the foil under the take-up sample to the physical detection, the physical detection personnel detects and feeds back the information, and then the staff of the foil process manually adjusts the parallelism of the polishing brush. The overall time span is large, the personnel adjustment randomness is large, the production efficiency is low, and the uniformity of the product after forming is poor.

[0033] To solve the technical problems in the related art, the foil polishing system provided in the present application is provided, see Figure 1 , Figure 1 is an embodiment structure schematic diagram of the foil polishing system provided in the present application.

[0034] The foil polishing system 10 comprises an initial roller 100, a winding roller 200, a gloss detector 300, a polishing assembly 400 and a controller 500, the initial roller 100 is wound with a foil 600; the winding roller 200 is used for winding the foil 600 of the initial roller 100; the gloss detector 300 is used for detecting the gloss of the foil 600 between the initial roller 100 and the winding roller 200; the polishing assembly 400 comprises a polishing piece 410, the polishing piece 410 is used for polishing the foil 600 on the initial roller 100; the controller 500 is used for adjusting the relative position relationship between the polishing piece 410 and the initial roller 100 according to the gloss of the foil 600 between the initial roller 100 and the winding roller 200 detected by the gloss detector 300, so as to change the gloss of the foil 600 on the initial roller 100 through the polishing piece 410.

[0035] The foil 600 can be a copper foil or a foil of other materials, which can be determined according to actual conditions. The initial roller 100 and the winding roller 200 can be in a cylindrical shape, and the foil 600 can be wound on the initial roller 100. In actual production, the foil 600 on the initial roller 100 needs to be peeled off, and then wound on the winding roller 200. In some embodiments, a peeling roller can also be arranged near the initial roller 100, which can be used to peel the foil 600 from the initial roller 100, so as to facilitate winding the foil 600 on the winding roller 200. There can be sufficient spacing between the initial roller 100 and the winding roller 200, so that the foil 600 is at least partially stretched between the initial roller 100 and the winding roller 200, and the gloss detector 300 can detect the gloss of the foil 600 between the initial roller 100 and the winding roller 200. The gloss can be used to characterize the flatness of the surface of the foil 600. The higher the gloss at a certain point, the higher the flatness of the surface of the foil 600 at the corresponding position. The lower the gloss at a certain point, the lower the flatness of the surface of the foil 600 at the corresponding position. The polishing member 410 can be used to polish the foil 600 on the initial roller 100, so as to change the gloss of the foil 600. For example, when the polishing member 410 contacts the foil 600, the initial roller 100 continues to rotate, so that the foil 600 moves relative to the polishing member 410, thereby increasing the gloss of the foil 600. The polishing member 410 can be in a cylindrical roller shape, and the gloss of the foil 600 can be changed by contacting the outer surface of the polishing member 410 with the surface of the foil 600.

[0036] The controller 500 can be in communication connection with the gloss detector 300 and the polishing assembly 400. The controller 500 can receive the gloss of the foil 600 detected by the gloss detector 300, and generate a control signal according to the received gloss, so as to control the polishing assembly 400 according to the control signal, thereby adjusting the relative position relationship between the polishing member 410 and the initial roller 100, so as to change the gloss of the foil 600 on the initial roller 100 by the polishing member 410.

[0037] Through the above embodiments, the controller 500 controls the polishing member 410 to change the gloss of the foil 600 on the initial roller 100, so as to automatically change the gloss of the foil 600, reduce the error caused by manual operation, improve the consistency of the gloss of the foil 600, and the controller 500 can adjust the relative position relationship between the polishing member 410 and the initial roller 100 in time according to the gloss of the foil 600 between the initial roller 100 and the winding roller 200 detected by the gloss detector 300, so as to improve the production efficiency and the qualified rate of the foil 600.

[0038] In some embodiments, the gloss detector 300 comprises a light receiver 310 and a light emitter 320, the light emitter 320 is configured to emit a light beam to the foil 600, and the light receiver 310 is configured to receive the light beam reflected by the foil 600. The light emitter 320 can be directed towards the foil 600, so that the light beam emitted by the light emitter 320 can be directly incident to the foil 600, and the light beam is reflected by the foil 600 after being incident to the foil 600, and the light receiver 310 is located on the light path of the light reflected by the foil 600 to receive the light beam reflected by the foil 600. The light receiver 310 can further analyze the received light beam to obtain the result of the light intensity analysis, and then send the result of the analysis to the controller 500.

[0039] In combination Figure 2 , Figure 2 is an embodiment structure schematic diagram of the initial roller 100 and the polishing assembly 400 provided by the present application.

[0040] The polishing assembly 400 comprises a first driving member 421 and a second driving member 422, the first driving member 421 and the second driving member 422 are arranged in the direction along the rotation axis O of the initial roller 100, and the first driving member 421 and the second driving member 422 are respectively connected to the polishing member 410, and the controller 500 is configured to control the first driving member 421 and / or the second driving member 422 to adjust the relative positional relationship between the polishing member 410 and the initial roller 100.

[0041] The initial roller 100 can be cylindrical, and can rotate along a central axis thereof when the foil 600 on the initial roller 100 is peeled, and the central axis can be defined as a rotation axis O of the initial roller 100, and a direction parallel to the rotation axis O of the initial roller 100 can be defined as a direction along the rotation axis O of the initial roller 100. The first driving member 421 and the second driving member 422 can both be stepping motors, and the polishing member 410 can be a polishing roller, and the first driving member 421 and the second driving member 422 are respectively connected at intervals in the direction along the rotation axis O of the initial roller 100, so that the first driving member 421 and the second driving member 422 are respectively connected at two ends of the initial roller 100. The controller 500 can control the first driving member 421 and the second driving member 422 to act independently of each other or to move synchronously according to the glossiness of the foil 600 between the initial roller 100 and the winding roller 200 detected by the glossiness detector 300, for example, the first driving member 421 can drive the polishing member 410 to move the end connected with the first driving member 421 to be close to or away from the initial roller 100, at this time, the second driving member 422 can also synchronously drive the polishing member 410 to move the end connected with the second driving member 422 to be close to or away from the initial roller 100; or the first driving member 421 can drive the polishing member 410 to move the end connected with the first driving member 421 to be close to or away from the initial roller 100, at this time, the second driving member 422 does not work, so that the end connected with the second driving member 422 of the polishing member 410 remains stationary; or the second driving member 422 can drive the polishing member 410 to move the end connected with the second driving member 422 to be close to or away from the initial roller 100, at this time, the first driving member 421 does not work, so that the end connected with the first driving member 421 of the polishing member 410 remains stationary.

[0042] Further, the glossiness detector 300 is used to detect the glossiness of a plurality of point positions of the foil 600 in the direction along the rotation axis O, and the controller 500 is used to control the first driving member 421 and / or the second driving member 422 to adjust the relative position relationship between the polishing member 410 and the initial roller 100 according to the glossiness of the plurality of point positions. The plurality of point positions of the foil 600 in the direction along the rotation axis O can be understood as: the plurality of point positions are in the width direction of the foil 600. The controller 500 can specifically adjust the first driving member 421 and / or the second driving member 422 according to the glossiness of each point position, so as to change the relative position relationship between the polishing member 410 and the initial roller 100. Or the controller 500 can also simultaneously refer to the glossiness of each point position and the position of the point position in the width direction, so as to adjust the first driving member 421 and / or the second driving member 422.

[0043] Furthermore, the gloss of multiple points includes the first gloss of the first point 610, which corresponds to the first drive member 421 in the foil exit direction X of the foil 600. The controller 500 is used to control the first drive member 421 to drive the polishing member 410 closer to the initial roller 100 in the foil exit direction X in response to the first gloss being greater than a preset gloss threshold. The foil exit direction X of the foil 600 can be understood as the direction in which the foil 600 moves after being peeled from the initial roller 100. The preset gloss threshold can be set according to actual conditions and is not limited here. The correspondence between the first point 610 and the first drive member 421 in the foil exit direction X of the foil 600 can be understood as follows: the foil 600 is divided into two equal parts along its width direction, and the first drive member 421 and the second drive member 422 correspond one-to-one with the two equal parts of the foil 600. The first point 610 is located within the portion of the foil 600 corresponding to the first drive member 421. For example, Figure 2 For example, the foil 600 can be divided into two parts along its width. The first driving member 421 corresponds to the left part of the foil 600, and the second driving member 422 corresponds to the right part of the foil 600. The first point 610 is located on the left side of the foil 600, which can be defined as the first point 610 corresponding to the first driving member 421. When the first gloss of the first point 610 is detected to be greater than the preset gloss threshold, it can be determined that the first gloss at the first point 610 is large. The foil 600 at the large gloss is easily oxidized. Therefore, it is necessary to control the first driving member 421 to drive the polishing member 410 closer to the initial roller 100 so that the polishing member 410 can polish the foil 600 on the initial roller 100 corresponding to the first point 610, thereby changing the gloss of the foil 600 at that position.

[0044] Furthermore, the gloss of multiple points includes the second gloss of the second point 620, which corresponds to the second drive member 422 in the foil exit direction X. The controller 500 is used to control the second drive member 422 to drive the polishing member 410 closer to the initial roller 100 in the foil exit direction X in response to the second gloss being greater than a preset gloss threshold. The correspondence between the second point 620 and the second drive member 422 in the foil exit direction X of the foil 600 can be understood as follows: the foil 600 is divided into two equal parts along its width direction, and the first drive member 421 and the second drive member 422 correspond one-to-one with the two equal parts of the foil 600. The second point 620 is located within the portion of the foil 600 corresponding to the second drive member 422. For example, with Figure 2For example, the foil 600 can be divided into two parts along the width direction of the foil 600, the first driving member 421 corresponds to the foil 600 of the left part, the second driving member 422 corresponds to the foil 600 of the right part, the first point 610 is located on the left side of the foil 600, and the second point 620 corresponds to the foil 600 of the right part, that is, the first point 610 corresponds to the first driving member 421, and the second point 620 corresponds to the second driving member 422. When it is detected that the second glossiness of the second point 620 is greater than the preset glossiness threshold, it is determined that the second glossiness of the second point 620 is greater, and the foil 600 at the position with greater glossiness is easily oxidized, and thus it is necessary to control the second driving member 422 to drive the polishing member 410 to be close to the initial roller 100, so as to polish the foil 600 corresponding to the second point 620 on the initial roller 100 by the polishing member 410, thereby changing the glossiness of the foil 600 at the position.

[0045] Further, the glossiness of the plurality of points includes third glossiness of a third point 630, the third point 630 corresponds to between the first driving member 421 and the second driving member 422 in the foil-out direction X, and the controller 500 is configured to control the first driving member 421 and the second driving member 422 to drive the polishing member 410 to be close to the initial roller 100 in the foil-out direction X in response to the third glossiness being greater than the preset glossiness threshold. The third point 630 corresponds to between the first driving member 421 and the second driving member 422 in the foil-out direction X, which can be understood as follows: the foil 600 is divided into two equal parts along the width direction of the foil 600, the first driving member 421 and the second driving member 422 correspond to the two equal parts of the foil 600 in a one-to-one correspondence, and the third point 630 is located in both equal parts, that is, the third point 630 corresponds to the first driving member 421 and the second driving member 422. For example, the first driving member 421 and the second driving member 422 are located on the left side of the foil 600, and the third point 630 is located on the right side of the foil 600. Figure 2For example, the foil 600 can be divided into two parts along the width direction of the foil 600, the first driving member 421 corresponds to the left part of the foil 600, the second driving member 422 corresponds to the right part of the foil 600, the first point 610 is located on the left side of the foil 600, the second point 620 corresponds to the right part of the foil 600, and the third point 630 is located between the first point 610 and the second point 620. That is, the first point 610 corresponds to the first driving member 421, the second point 620 corresponds to the second driving member 422, and the third point 630 corresponds to the first driving member 421 and the second driving member 422. When the third glossiness of the third point 630 is greater than the preset glossiness threshold, it is determined that the third glossiness of the third point 630 is greater, and the foil 600 at the position with greater glossiness is easily oxidized. Therefore, the first driving member 421 and the second driving member 422 are controlled to drive the polishing member 410 to approach the initial roller 100, so as to polish the foil 600 corresponding to the third point 630 on the initial roller 100 by the polishing member 410, thereby changing the glossiness of the foil 600 at the position.

[0046] In other embodiments, the first driving member 421 and / or the second driving member 422 can also be controlled to drive the polishing member 410 to approach the initial roller 100 in the foil-out direction X according to the distance between the first point 610 and the second point 620 and the third point 630. For example, when the first point 610 is on the edge away from the third point 630, only the first driving member 421 needs to be controlled to drive the polishing member 410 to approach the initial roller 100 in the foil-out direction X. When the first point 610 is close to the third point 630, the first driving member 421 and the second driving member 422 can be controlled to drive the polishing member 410 to approach the initial roller 100 in the foil-out direction X, but the movement path of the polishing member 410 driven by the second driving member 422 can be smaller than the movement path of the polishing member 410 driven by the first driving member 421. Similarly, when the second point 620 is on the edge away from the third point 630, only the second driving member 422 needs to be controlled to drive the polishing member 410 to approach the initial roller 100 in the foil-out direction X. When the second point 620 is close to the third point 630, the first driving member 421 and the second driving member 422 can be controlled to drive the polishing member 410 to approach the initial roller 100 in the foil-out direction X, but the movement path of the polishing member 410 driven by the first driving member 421 can be smaller than the movement path of the polishing member 410 driven by the second driving member 422.

[0047] In summary, the controller 500 is used to control the polishing member 410 to change the glossiness of the foil 600 on the initial roller 100, so as to automatically change the glossiness of the foil 600, reduce the error caused by manual operation, improve the consistency of the glossiness of the foil 600, and the controller 500 can adjust the relative position relationship between the polishing member 410 and the initial roller 100 in time according to the glossiness of the foil 600 between the initial roller 100 and the winding roller 200 detected by the glossiness detector 300, improve the production efficiency and the qualified rate of the foil 600, and the like.

[0048] To solve the technical problems in the related art, the present application provides a foil polishing method, which can be applied to the foil polishing system of any of the above embodiments, as shown in Figure 3 , Figure 3 is an embodiment flow diagram of the foil polishing method provided by the present application.

[0049] Step S301: Obtain the glossiness of the foil between the initial roller and the winding roller detected by the glossiness detector.

[0050] The controller of the foil polishing system can be used to obtain the glossiness of the foil between the initial roller and the winding roller detected by the glossiness detector. The glossiness can be used to characterize the flatness of the surface of the foil. When the glossiness of a certain point is higher, it indicates that the flatness of the surface of the foil at the corresponding position of the point is higher; when the glossiness of a certain point is lower, it indicates that the flatness of the surface of the foil at the corresponding position of the point is lower.

[0051] Step S302: Adjust the relative position relationship between the polishing member and the initial roller according to the glossiness of the foil, so as to change the glossiness of the foil on the initial roller by the polishing member.

[0052] The polishing member can be used to polish the foil on the initial roller, so as to change the glossiness of the foil. For example, when the polishing member contacts the foil, the initial roller and / or the polishing member continues to rotate, so that the foil moves relative to the polishing member, thereby improving the glossiness of the foil. The polishing member can be in the form of a cylindrical roller, and the glossiness of the foil can be changed by contacting the outer surface of the polishing member with the surface of the foil. The controller can be in communication connection with the glossiness detector and the polishing member. The controller can receive the glossiness of the foil detected by the glossiness detector, and generate a control signal according to the received glossiness, so as to control the relative position relationship between the polishing member and the initial roller according to the control signal, so as to change the glossiness of the foil on the initial roller by the polishing member.

[0053] Through the above implementation method, the polishing part is controlled to change the gloss of the foil on the initial roller, thereby realizing the automatic change of the foil gloss, reducing the error caused by manual operation, improving the consistency of foil gloss, and the relative positional relationship between the polishing part and the initial roller can be adjusted in time according to the gloss of the foil between the initial roller and the winding roller detected by the gloss detector, thereby improving production efficiency and foil qualification rate.

[0054] Further, the step of adjusting the relative positional relationship between the polishing component and the initial roller according to the gloss of the foil includes: in response to a first gloss level at a first point among a plurality of points being greater than a preset gloss threshold, controlling a first driving component to move the polishing component closer to the initial roller in the foil exit direction, wherein the first point corresponds to the first driving component in the foil exit direction; in response to a second gloss level at a second point among a plurality of points being greater than a preset gloss threshold, controlling a second driving component to move the polishing component closer to the initial roller in the foil exit direction, wherein the second point corresponds to the second driving component in the foil exit direction.

[0055] The preset gloss threshold can be set according to actual conditions and is not limited here. The first point corresponding to the first driving member in the foil exit direction can be understood as follows: the foil is divided into two equal parts along its width direction, and the first and second driving members correspond one-to-one with the two equal parts of the foil. The first point is located within the portion of the foil corresponding to the first driving member. For example, using... Figure 2 For example, the foil can be divided into two parts along its width. The first driving component corresponds to the left part of the foil, and the second driving component corresponds to the right part. The first point is located on the left side of the foil, which can be defined as the first point corresponding to the first driving component. When the gloss level of the first point is detected to be greater than a preset gloss level threshold, it can be determined that the gloss level at the first point is relatively high. The foil at the point with higher gloss level is easily oxidized. Therefore, it is necessary to control the first driving component to drive the polishing component closer to the initial roller, so that the polishing component can polish the foil on the initial roller corresponding to the first point, thereby changing the gloss level of the foil at that position.

[0056] The second point, corresponding to the second driving member in the foil exit direction, can be understood as follows: the foil is divided into two equal parts along its width direction, with the first and second driving members corresponding one-to-one with the two equal parts of the foil, and the second point located within the portion of the foil corresponding to the second driving member. For example, using... Figure 2For example, the foil can be divided into two parts along the width direction of the foil, the first driving member corresponds to the foil of the left part, the second driving member corresponds to the foil of the right part, the first point is located on the left side of the foil, and the second point corresponds to the foil of the right part, that is, the first point corresponds to the first driving member, and the second point corresponds to the second driving member. When it is detected that the second glossiness of the second point is greater than the preset glossiness threshold, it is determined that the second glossiness at the second point is large, and the foil at the large glossiness is easy to be oxidized, so the second driving member needs to be controlled to drive the polishing member close to the initial roller to polish the foil corresponding to the second point on the initial roller by the polishing member, so as to change the glossiness of the foil at the position.

[0057] Further, the step of adjusting the relative position relationship between the polishing member and the initial roller according to the glossiness of the foil further comprises: in response to the third glossiness of the third point in the plurality of points being greater than the preset glossiness threshold, controlling the first driving member and the second driving member to drive the polishing member to move close to the initial roller in the out-foil direction, wherein the third point corresponds to the first driving member and the second driving member in the out-foil direction.

[0058] The third point corresponds to the first driving member and the second driving member in the out-foil direction, which means that the foil is equally divided along the width direction of the foil, the first driving member and the second driving member correspond to the two equally divided foils, and the third point is located in both equally divided foils, that is, the third point corresponds to the first driving member and the second driving member. For example, the foil can be divided into two parts along the width direction of the foil, the first driving member corresponds to the foil of the left part, the second driving member corresponds to the foil of the right part, the first point is located on the left side of the foil, and the second point corresponds to the foil of the right part, that is, the first point corresponds to the first driving member, and the second point corresponds to the second driving member. When it is detected that the second glossiness of the second point is greater than the preset glossiness threshold, it is determined that the second glossiness at the second point is large, and the foil at the large glossiness is easy to be oxidized, so the second driving member needs to be controlled to drive the polishing member close to the initial roller to polish the foil corresponding to the second point on the initial roller by the polishing member, so as to change the glossiness of the foil at the position. Figure 2

[0059] In summary, the polishing member is controlled to change the glossiness of the foil on the initial roller, thereby realizing automatic change of the glossiness of the foil, reducing the error caused by manual operation, improving the consistency of the glossiness of the foil, and timely adjusting the relative position relationship between the polishing member and the initial roller according to the glossiness of the foil between the initial roller and the winding roller detected by the glossiness detector, thereby improving the production efficiency and the pass rate of the foil. ​
