[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0048] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0049] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or service tool that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or service tool.

[0050] With the development of new energy sources, the demand for current collector materials is also increasing. Copper foil can be used to prepare current collectors for lithium-ion batteries due to its excellent conductivity, good flexibility, moderate potential and mature production process.

[0051] The prepared copper foil can be wound on a winding roll to form a copper foil roll. That is to say, the copper foil roll includes a winding roll and multiple layers of copper foil wound on the winding roll layer by layer. The copper foil roll needs to be tested to determine whether it is qualified. In the production process of copper foil, there are multiple factors that affect the yield of copper foil, so the yield of copper foil is not 100%, which will produce a certain number of unqualified copper foil. Qualified copper foil can be used to prepare current collectors, and unqualified copper foil needs to be recycled. However, the unqualified copper foil has been wound on the winding roll, so the copper foil needs to be peeled off the winding roll. In the related art, the copper foil can be cut layer by layer manually, peeled off the winding roll, and then transported to the copper foil compression equipment, and the compressed copper foil can be recycled.

[0052] In the related art, the recycling process of copper foil is time-consuming and labor-intensive, resulting in high labor costs for copper foil recycling.

[0053] Based on this, the present application provides a copper foil recycling device. The process of recycling copper foil using the copper foil recycling device saves time and labor, and can reduce the labor cost of copper foil recycling.

[0055] See also Figures 1 to 3 As shown, the copper foil recycling device 100 includes: a conveying mechanism 110, a positioning mechanism 130, a cutting mechanism 140, a coil roller conveying mechanism 150 and a copper foil compression mechanism 160; the positioning mechanism 130, the cutting mechanism 140 and the coil roller conveying mechanism 150 are arranged in sequence along the travel direction T of the conveying mechanism 110, and the copper foil compression mechanism 160 is located at the end of the travel direction T; the positioning mechanism 130 is used to align the copper foil roll 200 with the cutting mechanism 140; the conveying mechanism 110 is used to move the copper foil roll 200 along the travel direction T; the cutting mechanism 140 is used to peel the copper foil 210 from the coil roller 220; the coil roller conveying mechanism 150 is used to move the coil roller 220 away from the conveying mechanism; the copper foil compression mechanism 160 is used to compress the copper foil 210, wherein the copper foil roll 200 includes a coil roller 220 and a multilayer copper foil 210 wound on the coil roller 220.

[0056] First, the specific structure of the copper foil roll 200 is described. Figure 3 As shown, the copper foil roll 200 includes a winding roll 220 and a copper foil 210. The winding roll 220 is cylindrical, and the multi-layer copper foil 210 is wound on the outside of the winding roll 220. The copper foil roll 200 includes an axial direction L and a radial direction R.

[0057] The copper foil recycling device 100 further includes a copper foil roll conveying mechanism 120. The copper foil roll conveying mechanism 120 can convey the copper foil roll 200 to place the copper foil roll 200 on the conveying mechanism 110. The copper foil roll conveying mechanism 120 can be a conveying vehicle with rollers, or a hoisting mechanism or other conveying mechanisms.

[0058] In the following, the copper foil roll conveying mechanism 120 is described as a conveying vehicle with rollers. Specifically, the copper foil roll conveying mechanism 120 is further provided with rolling wheels 121, so that the copper foil roll conveying mechanism 120 can move. The copper foil roll conveying mechanism 120 may include a clamping portion, which is used to clamp the copper foil roll 200. For example, the clamping portion may clamp the copper foil roll 200 on two opposite sides of the radial direction R to place the copper foil roll 200 on the conveying mechanism 110.

[0059] The copper foil roll conveying mechanism 120 may further include a copper foil roll conveying mechanism body, a folding arm and a controller, wherein one end of the folding arm is connected to the clamping portion, and the other end of the folding arm is connected to the copper foil roll conveying mechanism body, and a moving path of the folding arm is preset in the controller.

[0060] The controller controls the folding arm to drive the clamping part to move according to the preset path, so that when the copper foil roll 200 is placed on the conveyor belt 112 of the conveying mechanism 110, the axial direction L of the copper foil roll 200 is consistent with the travel direction T. By setting the copper foil roll conveying mechanism 120, the copper foil roll 200 can be moved to the conveying mechanism 110, avoiding manual conveyance of the copper foil roll 200 to the conveying mechanism 110.

[0061] The conveying mechanism 110 may include a support body 111, a conveyor belt 112 and a driving motor (not shown in the figure). The support body 111 is used to support the conveyor belt 112 to a certain height, and the driving motor may be installed on the support body 111. The driving motor may drive the conveyor belt 112 to move on the support body 111, and the direction of movement of the conveyor belt 112 is the travel direction T; the direction perpendicular to the travel direction T is the width direction W. By providing the conveying mechanism 110 and moving the copper foil roll 200 on the conveying mechanism 110, manual handling of the copper foil roll 200 may be avoided, and the recycling of the copper foil roll 200 may be continuously operated, so that the transportation process of the copper foil roll 200 during the recycling process of the copper foil 210 is time-saving and labor-saving.

[0062] The positioning mechanism 130 can adjust the specific position of the copper foil roll 200 on the conveyor belt 112 so that the copper foil roll 200 is aligned with the cutting mechanism 140 along the travel direction T. The cutting mechanism 140 is usually centered along the width direction W of the conveyor belt 112, so the copper foil roll 200 can also be centered along the width direction W. By adjusting the position of the copper foil roll 200 by the positioning mechanism 130 so that the copper foil roll 200 is aligned with the cutting mechanism 140, it can be avoided that the cutting mechanism 140 mistakenly cuts the coiling roll 220, causing the coiling roll 220 to be unable to be reused, thereby saving material costs in the copper foil 210 recycling process.

[0063] After the positioning mechanism 130 adjusts the position of the copper foil roll 200, the conveyor belt 112 on the conveying mechanism 110 starts to move, so as to drive the copper foil roll 200 on the conveyor belt 112 to move along the travel direction T toward the cutting mechanism 140. After the copper foil roll 200 moves to the cutting mechanism 140, as the copper foil roll 200 continues to move along the travel direction T, the cutting mechanism 140 cuts the copper foil 210 on the outside of the coiling roll 220 into multiple pieces, so as to separate the copper foil 210 from the coiling roll 220. The cutting can be completed during the movement of the copper foil roll 200, which further improves the recycling efficiency of the copper foil roll 200.

[0064] The separated copper foil 210 and the coiling roll 220 continue to move along the traveling direction T with the conveyor belt 112. When the separated copper foil 210 and the coiling roll 220 move to the coiling roll conveying mechanism 150, the coiling roll conveying mechanism 150 moves the coiling roll 220 away from the conveyor belt 112. The coiling roll conveying mechanism 150 conveys the coiling roll 220, which can avoid manual conveyance of the coiling roll 220, so that the transportation process of the coiling roll 220 during the recovery process of the copper foil 210 is time-saving and labor-saving.

[0065] The copper foil 210 continues to move along the travel direction T, and the copper foil 210 enters the copper foil compression mechanism 160 located at the end of the travel direction. The copper foil compression mechanism 160 compresses the copper foil 210 into a smaller volume, thereby completing the recycling of the copper foil 210. By compressing the copper foil 210 into a smaller volume by the copper foil compression mechanism 160, the volume occupied by the recycled copper foil 210 can be saved. In addition, since the copper foil 210 has been cut into multiple pieces, the recycling of the copper foil 210 is more troublesome than the recycling of the coiling roll 220. Placing the recycling of the copper foil 210 after the recycling of the coiling roll 220 can facilitate the operation.

[0066] The copper foil recycling device 100 provided in the embodiment of the present application is provided with a conveying mechanism 110, a positioning mechanism 130, a cutting mechanism 140, a coil roller conveying mechanism 150 and a copper foil compression mechanism 160; the positioning mechanism 130, the cutting mechanism 140 and the coil roller conveying mechanism 150 are arranged in sequence along the travel direction T of the conveying mechanism 110, and the copper foil compression mechanism 160 is located at the end of the travel direction T; the positioning mechanism 130 is used to align the copper foil roll 200 with the cutting mechanism 140, and the position of the copper foil roll 200 is adjusted by the positioning mechanism 130 so that the copper foil roll 200 is aligned with the cutting mechanism 140, which can avoid the cutting mechanism 140 from mistakenly cutting the coil roller 220, causing the coil roller 220 to be unable to be reused, thereby saving the material cost in the copper foil 210 recycling process. The conveying mechanism 110 is used to move the copper foil roll 200 along the travel direction T. By providing the conveying mechanism 110 and moving the copper foil roll 200 on the conveying mechanism 110, manual handling of the copper foil roll 200 can be avoided, and the copper foil roll 200 can be recycled continuously, so that the transportation process of the copper foil roll 200 is time-saving and labor-saving during the recycling process of the copper foil 210. The cutting mechanism 140 is used to peel the copper foil 210 from the coil roll 220, and the cutting can be completed during the movement of the copper foil roll 200, further improving the recycling efficiency of the copper foil roll 200. The coil roller transport mechanism 150 is used to move the coil roller 220 away from the conveying mechanism 110, which can avoid manual transport of the coil roller 220, so that the transportation process of the coil roller 220 during the recycling process of the copper foil 210 is time-saving and labor-saving; the copper foil compression mechanism 160 is used to compress the copper foil 210. The copper foil compression mechanism 160 compresses the copper foil 210 into a smaller volume, which can save the volume occupied by the recycled copper foil 210. The process of recycling the copper foil 210 using the copper foil recycling device 100 is time-saving and labor-saving, and the labor cost of recycling the copper foil 210 can be reduced.

[0067] Next, the specific structure of the positioning mechanism 130 will be described.

[0068] Figure 4 This is a schematic structural diagram of a positioning mechanism in a copper foil recovery device provided in an embodiment of the present application.

[0069] See also Figure 1 , Figure 2 and Figure 4 As shown, the positioning mechanism 130 includes a first motor 131 and two positioning components 132. The two positioning components 132 are arranged on both sides of the conveying mechanism 110 along the width direction W of the conveying mechanism 110, and the two positioning components 132 are both connected to the first motor 131; the first motor 131 is used to drive the two positioning components 132 to move toward or away from each other at the same time, so that the copper foil roll 200 is aligned with the cutting mechanism 140 along the travel direction T.

[0070] The two positioning components 132 are symmetrically arranged on both sides of the conveying mechanism 110 along the width direction W. The first motor 131 can be arranged below the conveying belt 112. Figure 1 and Figure 2 In the embodiment, the first motor 131 is blocked by the side wall of the support body 111 .

[0071] The positioning assembly 132 may include a screw rod 1321, a slider 1322, a transfer rod 1323 and a positioning plate 1324. The screw rod 1321 is connected to the rotating shaft of the first motor 131, and the slider 1322, the transfer rod 1323 and the positioning plate 1324 are connected in sequence. When the rotating shaft of the first motor 131 rotates, the slider 1322 can be driven to move on the screw rod 1321, thereby driving the positioning plate 1324 to move along the width direction W.

[0072] When the first motor 131 is running forward, the two sliders 1322 move toward each other, thereby driving the positioning pieces 1324 to move toward each other through the transfer rod 1323, and the two positioning pieces 1324 abut against both sides of the copper foil roll 200, so that the copper foil roll 200 is aligned with the cutting mechanism 140. Then, the first motor 131 is reversed, and the two sliders 1322 move away from each other, thereby driving the positioning pieces 1324 to move away from each other through the transfer rod 1323, so as to complete the positioning of the copper foil roll 200.

[0073] Please continue to see Figure 1 and Figure 2 As shown, the positioning mechanism 130 also includes a pushing rod 133 and a pushing plate 134, and the pushing rod 133 is connected to the pushing plate 134; when the position of the copper foil roll 200 needs to be adjusted along the travel direction T, the pushing plate 134 is used to abut against the end surface of the copper foil roll 200 and push the copper foil roll 200 under the drive of the pushing rod 133.

[0074] Different copper foil rolls 200 may have different sizes along their axial direction L. Therefore, when the copper foil roll conveying mechanism 120 conveys the copper foil roll 200 to the conveying mechanism 110, it is necessary to adjust the position of the copper foil roll 200 along the travel direction T. In this case, by applying a force to the push rod 133, the push plate 134 abuts against the end surface of the copper foil roll 200 under the drive of the push rod 133 and pushes the copper foil roll 200, thereby adjusting the position of the copper foil roll 200 along the travel direction T.

[0075] Next, the specific structure of the cutting mechanism 140 will be described.

[0077] See also Figures 5 to 7 As shown, the cutting mechanism 140 includes a first blade 141, a second blade 142 and a third blade 143. The first blade 141 is parallel to the bearing surface of the conveying mechanism 110, and the second blade 142 and the third blade 143 are respectively arranged on both sides of the first blade 141; the distance between the second blade 142 and the third blade 143 is the diameter of the coil roller 220.

[0078] The bearing surface of the conveying mechanism 110 is the conveyor belt 112. The first blade 141 and the conveyor belt 112 are arranged opposite to each other, and the second blade 142 and the third blade 143 are arranged opposite to each other. The first blade 141, the conveyor belt 112, the second blade 142 and the third blade 143 form a cutting frame.

[0079] The diameter of the coiling roller 220 is shown as the coiling roller diameter D, the thickness of the copper foil 210 on the coiling roller 220 is shown as the copper foil thickness H, the spacing between the first blade 141 and the conveyor belt 112 is the first spacing D1, and the first spacing D1 is the sum of the coiling roller diameter D and the copper foil thickness H. The spacing between the second blade 142 and the third blade 143 is the second spacing D2, and the second spacing D2 is equal to the coiling roller diameter D.

[0080] Thus, when the copper foil roll 200 travels along the travel direction T on the conveyor belt 112, the first blade 141, the second blade 142 and the third blade 143 are all in contact with the outer wall of the coiling roll 220, and the first blade 141, the second blade 142 and the third blade 143 cut the copper foil 210 on the coiling roll 220 into Figure 6 1 , 2, 3, 4, 5, 215, and 6, 216 are shown in FIG.

[0081] Please continue to see Figure 5 and Figure 6 As shown, the first blade 141, the second blade 142 and the third blade 143 each include a first end 140a and a second end 140b opposite to each other, the first end 140a faces the positioning mechanism 130, and the first end 140a has a first cutting edge 140c; the thickness of the first blade 141, the second blade 142 and the third blade 143 each gradually increases from the first end 140a to the second end 140b.

[0082] The first cutting edge 140c is provided on the first end 140a, so that the first blade 141, the second blade 142 and the third blade 143 can facilitate cutting of the copper foil 210. The thickness of the first blade 141, the second blade 142 and the third blade 143 gradually increases from the first end 140a to the second end 140b, and while increasing the strength of the first blade 141, the second blade 142 and the third blade 143, it is also convenient to peel the copper foil 210 from the coiling roll 220 as the copper foil roll 200 moves.

[0083] Please continue to see Figure 1 and Figure 2 As shown, the cutting mechanism 140 also includes an adjusting rod 144. The first blade 141, the second blade 142 and the third blade 143 are each provided with an adjusting rod 144. The three adjusting rods 144 can be electrically connected to the driving member. The driving member can adjust the distance between the second blade 142 and the third blade 143 through the adjusting rod 144. The driving device can also adjust the distance between the first blade 141 and the conveyor belt 112, so that the cutting mechanism 140 can be adapted to the diameter of the coil roller 220.

[0086] See also Figures 8 to 13 As shown, the cutting mechanism 140 includes a mounting cylinder 145 and a plurality of fourth blades 146. The plurality of fourth blades 146 are arranged at intervals on the mounting cylinder 145 along the circumference of the mounting cylinder 145 and all extend toward the center of the mounting cylinder 145. The end of the fourth blade 146 facing the positioning mechanism 130 has a second cutting edge 1461, and the side of the fourth blade 146 facing the winding roller 220 is a blunt surface.

[0087] When the copper foil roll 200 moves to the cutting mechanism 140 , the copper foil roll 200 enters the mounting cylinder 145 , and as the copper foil roll 200 continues to move, the plurality of fourth blades 146 cut the copper foil 210 on the copper foil roll 200 .

[0088] Please continue to see Fig.13 As shown, the end of the fourth blade 146 facing the positioning mechanism 130 has a second cutting edge 1461, and the second cutting edge 1461 is used to cut the copper foil 210. The side of the fourth blade 146 facing the coiling roller 220 is a first surface 1462, and the first surface 1462 is a blunt surface, thereby preventing the first surface 1462 from scratching the coiling roller 220.

[0089] Please continue to see Figures 8 to 12 As shown, the installation cylinder 145 also has a through hole 1451 extending along the axial direction of the installation cylinder 145, and the through hole 1451 faces the conveyor belt 112, so as to facilitate the installation cylinder 145 to be set on the conveyor mechanism 110. The cutting mechanism 140 also includes a mounting rod (not shown in the figure), which is used to support the installation cylinder 145.

[0090] Next, the specific structure of the web roll conveying mechanism 150 will be described.

[0091] Please continue to see Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the material roller transport mechanism 150 includes a support rod 151, a second motor 152 and a rotating rod 153. The second motor 152 is arranged on the support rod 151, and the rotating rod 153 is connected to the rotating shaft of the second motor 152. When the material roller 220 needs to be moved away from the conveying mechanism 110, the rotating rod 153 is used to extend into the material roller 220, and the rotating rod 153 moves the material roller 220 away from the conveying mechanism 110 under the drive of the second motor 152.

[0092] Specifically, the rotating rod 153 is located above the conveyor belt 112, and the axis of the rotating rod 153 can be aligned with the axis of the coiling roller 220. After the copper foil roll 200 is cut, the copper foil 210 is peeled off from the coiling roller 220, and the copper foil 210 and the coiling roller 220 continue to move on the conveyor belt 112. The coiling roller 220 has a through hole 221. As the coiling roller 220 moves on the conveyor belt 112, the rotating rod 153 extends into the through hole 221 of the coiling roller 220, and then the second motor 152 drives the rotating rod 153 to rotate, thereby moving the coiling roller 220 away from the conveyor belt 112. Figure 2 and Fig. 9 The dotted line in FIG. 2 shows the removal process of the web roller 220 .

[0093] The peeled copper foil 210 continues to move along the moving direction T, enters the copper foil compression mechanism 160 , and is compressed by the copper foil compression mechanism 160 .

[0094] Next, the specific structure of the copper foil compression mechanism 160 will be described.

[0095] Fig.14 A top view of a copper foil compression mechanism in a copper foil recovery device provided in an embodiment of the present application.

[0096] See also Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.14 As shown, the copper foil compression mechanism 160 includes a first compression plate 161, a second compression plate 162, and a third compression plate 163, and the first compression plate 161, the second compression plate 162, and the third compression plate 163 are used to compress the copper foil 210 from three orthogonal directions. The copper foil compression mechanism 160 also includes a box body 164, and the box body 164 includes a bottom wall 1641 and two side walls adjacent to the bottom wall 1641; the first compression plate 161 is opposite to the bottom wall 1641; the second compression plate 162 is opposite to one of the side walls, and the third compression plate 163 is opposite to the other side wall.

[0097] The three orthogonal directions are respectively a first direction X, a second direction Y and a third direction Z. The side wall opposite to the second compression plate 162 is a first side wall 1642 a , and the side wall 1642 opposite to the third compression plate 163 is a second side wall 1642 b .

[0098] The bottom wall 1641, the first side wall 1642a and the second side wall 1642b form an open accommodation cavity, which is used to accommodate the copper foil 210. After the copper foil 210 enters the accommodation cavity, the first compression plate 161 moves toward the bottom wall 1641 along the third direction Z, and the first compression plate 161 and the bottom wall 1641 compress the copper foil 210 along the third direction Z.

[0099] The second compression plate 162 moves along the second direction Y toward the first side wall 1642 a , and the second compression plate 162 and the first side wall 1642 a compress the copper foil 210 along the second direction Y.

[0100] The third compression plate 163 moves toward the second side wall 1642b along the first direction X, and the third compression plate 163 and the second side wall 1642b compress the copper foil 210 along the first direction X. It should be noted that the dimension of the third compression plate 163 along the second direction Y is smaller than the dimension of the second side wall 1642b along the second direction Y, thereby preventing the second compression plate 162 and the third compression plate 163 from interfering with each other when compressing the copper foil 210.

[0101] The first compression plate 161 , the second compression plate 162 , and the third compression plate 163 are each provided with a driving rod 165 to drive the first compression plate 161 , the second compression plate 162 , and the third compression plate 163 to move respectively.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
