[0003] In the related art, a foil machine is a device that produces foil by electrolysis in a copper sulfate solution, and usually requires continuous and uninterrupted production. The existing foil machine includes a conveying device and a winding roller, and the conveying device is used to convey the generated copper foil to the winding roller. When the winding roller is full or needs to be changed for other reasons, the foil machine can still produce foil normally because the process of electrolysis of foil is uninterrupted.

DETAILED DESCRIPTION

[0028] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0033] The following first describes in detail the conveying device 100 according to an embodiment of the present application with reference to the accompanying drawings.

[0034] As shown in FIG. 1 to FIG. 5 , the conveying device 100 according to an embodiment of the present application includes: a bracket 10 , a first roller 20 , a first driving member 30 , a second roller 40 and a second driving member 50 .

[0035] Specifically, a first roller 20 is rotatably mounted on the bracket 10 about its own axis. The first roller 20 is configured to receive the sheet 200 and convey the sheet 200 to the winding roller. A first driving member 30 is mounted on the bracket 10 and has a movable end 31 that is movable in a first direction. A second roller 40 is rotatably mounted on the movable end 31 about its own axis. The first driving member 30 drives the second roller 40 to move in the first direction between a first state and a second state. A second driving member 50 is connected to the second roller 40 to drive the second roller 40 to rotate. When the second roller 40 is in the first state, the second roller 40 is spaced apart from the first roller 20. When the second roller 40 is in the second state, the second roller 40 cooperates with the first roller 20 to clamp and convey the sheet 200.

[0036] In other words, the conveying device 100 according to the embodiment of the present application is mainly composed of a bracket 10, a first roller 20, a first driving member 30, a second roller 40 and a second driving member 50. The bracket 10 can serve as a carrier to carry the first roller 20 and the first driving member 30, and the first roller 20 can rotate around its own axis.

[0037] The first roller 20 can guide and output the sheet 200, and the sheet 200 can be wound around the outer circumference of the first roller 20. Specifically, the sheet 200 can move from the upstream a of the first roller 20 toward the first roller 20, and under the guidance of the first roller 20, move to the winding roller downstream b of the first roller 20. Optionally, the sheet 200 can include, but is not limited to, copper foil.

[0038] The first driving member 30 may have a movable end 31, which can move along a first direction. The first direction may be any direction intersecting the axis of the first roller 20. For ease of description, the axial direction of the first roller 20 may be defined as the second direction.

[0039] The second roller 40 can be rotatably connected to the movable end 31 of the first driving member 30. It should be noted that the connection between the second roller 40 and the first driving member 30 can be direct or indirect, and is not limited here. Furthermore, the first driving member 30 and the second driving member 50 can each be manually operated, electrically operated, or pneumatically operated, and are not limited here.

[0040] When the movable end 31 of the first driving member 30 moves in the first direction, it can drive the second roller 40 to move between the first state and the second state. Furthermore, the second roller 40 is connected to the second driving member 50 and can rotate about its own axis under the drive of the second driving member 50. In other words, the second roller 40 can be formed as an active roller, and the first roller 20 can be formed as a driven roller.

[0041] Specifically, when the second roller 40 is in the first state, the second roller 40 can be spaced apart from the first roller 20, and the second roller 40 can be spaced apart from the sheet 200 on the first roller 20. Under the traction force of the winding roller, the sheet 200 can move along the outer peripheral surface of the first roller 20, and the first roller 20 can tension the sheet 200.

[0042] When the second roller 40 is in the second state, the second roller 40 can cooperate with the first roller 20 to clamp the sheet 200. Under the action of the second driving member 50, the second roller 40 can provide traction for pulling the sheet 200 to move. Therefore, the first roller 20 and the second roller 40 can cooperate to continue to convey the sheet 200 and maintain the tension of the sheet 200.

[0043] The following takes the conveying device 100 disposed in a foil production machine as an example to describe in detail the working process of the conveying device 100 during the roll changing process of this embodiment.

[0044] When the reel is fully wound or needs to be rewound for other reasons, the copper sulfate in the foil machine is likely to continue to produce copper foil without interruption. When reeling, before cutting the copper foil between the reel and the first roller 20, the second roller 40 is first driven to rotate about its own axis by the second driving member 50. Then, the second roller 40 is driven by the second first driving member 30 to approach the first roller 20 in a first direction until the second roller 40 is in contact with the copper foil wound around the first roller 20 and presses the copper foil, thus switching the second roller 40 from the first state to the second state. The copper foil between the reel and the first roller 20 is then cut. Since the second roller 40 rotates about its own axis under the drive of the second driving member 50, the second roller 40, while cooperating with the first roller 20 to clamp the copper foil, continues to transport the copper foil to the downstream side b, maintaining a stable and appropriate tension on the copper foil at the upstream side a. After reeling, the copper foil at the downstream side b of the conveying device 100 is wound onto the new reel. Therefore, during the production process and the roll changing process of the foil machine, the copper foil upstream a of the first roller 20 can always maintain a stable tension.

[0045] In addition, since the second roller 40 is in a rotating state when approaching the first roller 20, the second roller 40 can be pressed against the copper foil without stopping the machine, which is beneficial to saving roll changing time.

[0046] Therefore, according to the conveying device 100 of the embodiment of the present application, a movable second roller 40 is provided outside the first roller 20 for conveying the sheet 200. The second roller 40 and the first roller 20 can be used to clamp the sheet 200 during the roll changing process. At the same time, a second driving member 50 is provided to drive the second roller 40, so that the second roller 40 can be used as a power source to pull the sheet 200 to continue to move. The roll changing can be completed without stopping the machine, and the sheet 200 upstream a of the first roller 20 maintains a stable tension during the roll changing process. Compared with the manual pressing of the sheet 200 in the traditional technology, the conveying device 100 of this embodiment reduces the required labor, and the timing of clamping the sheet 200 is more precise, which can avoid the waste of sheet 200 accumulation and re-threading of the foil, which is beneficial to saving roll changing time and improving the output of the sheet 200.

[0047] In some optional embodiments, the first driving member 30 may be a cylinder having a telescopic rod, the end of which may form the movable end 31 of the first driving member 30. The cylinder may be provided with an air pipe connector 33, which may be connected to an air source.

[0048] In some optional embodiments, the second driving member 50 may be a motor, and the output shaft of the motor may be in transmission connection with the second roller 40 to drive the second roller 40 to rotate about its own axis. It should be noted that the output shaft of the motor may be coaxial with the second roller 40, or may be spaced apart from the second roller 40 and connected thereto via a transmission structure.

[0049] Preferably, the motor may be a servo motor, which can conveniently control the rotation angle and rotation speed of the second roller 40 to provide appropriate traction force and prevent the sheet 200 from being subjected to excessive tension.

[0050] In some specific embodiments, the axis of the second roller 40 can be roughly parallel to the axis of the first roller 20. Thus, when the second roller 40 and the first roller 20 cooperate to clamp the sheet 200, the outer peripheral surface of the first roller 20 and the outer peripheral surface of the second roller 40 are respectively in full contact with the sheet 200, thereby making the tension applied to each part of the sheet 200 roughly the same.

[0051] In some specific embodiments of the present application, the first roller 20 is an anti-oxidation roller, which can perform anti-oxidation treatment on the sheet 200 .

[0052] According to one embodiment of the present application, the conveying device 100 also includes a connecting plate 60, which is connected to the movable end 31, the second roller 40 is rotatably connected to the connecting plate 60 around its own axis, and the second driving member 50 is arranged on the side of the connecting plate 60 away from the second roller 40.

[0053] In other words, the second roller 40 and the movable end 31 of the first driving member 30 can be indirectly connected. Specifically, a connecting plate 60 can be provided between the second roller 40 and the movable end 31, and the second roller 40 can rotate about its own axis relative to the connecting plate 60. For example, in the first direction, the end of the connecting plate 60 away from the first roller 20 can be connected to the movable end 31, and the end of the second roller 40 can be connected to the connecting plate 60 via a bearing and a bearing seat 41, and the bearing seat 41 can be fixed to the connecting plate 60.

[0054] The second driving member 50 may be fixed on the connecting plate 60 , and the second driving member 50 may be located on a side of the connecting plate 60 away from the second roller 40 .

[0055] In this embodiment, a connecting plate 60 is provided between the second roller 40 and the movable end 31 , and the connecting plate 60 can be used to provide space for the installation of the second roller 40 , thereby facilitating the connection between the second roller 40 and a telescopic rod of a telescopic structure such as a cylinder.

[0056] According to some other embodiments of the present application, a limiting groove 62 is provided at one end of the connecting plate 60 close to the movable end 31, a limiting step 63 is provided at the notch 621 of the limiting groove 62, and the limiting groove 62 passes through one side of the connecting plate to form an opening, and also includes a driving connecting member 32, the driving connecting member 32 extends along the first direction, one end of the driving connecting member 32 is connected to the movable end 31, and the other end of the driving connecting member 32 is provided with a limiting block 321, the limiting block 321 is accommodated in the limiting groove 62, and the projection of the limiting step 63 along the first direction coincides with the projection of the limiting block 321 along the first direction, so as to limit the limiting block 321 in the first direction.

[0057] Specifically, the connecting plate 60 and the movable end 31 may be connected via a drive connector 32. The drive connector 32 may extend substantially along a first direction. In the first direction, the drive connector 32 may have two ends. The first end of the drive connector 32 may be connected to the movable end 31, and the second end of the drive connector 32 may be connected to the connecting plate 60.

[0058] Optionally, the connection between the driving connector 32 and the movable end 31 may be a fixed connection, such as welding, or a detachable connection, such as screw connection, which is not limited here.

[0059] A limiting groove 62 may be provided at one end of the connecting plate 60 close to the movable end 31 . The limiting groove 62 may extend roughly along the first direction. The notch 621 of the limiting groove 62 may face the movable end. The second end of the driving connecting member 32 may extend into the limiting groove 62 through the notch 621 .

[0060] A limiting step 63 may be provided at the notch 621 of the limiting groove 62, and the limiting step 63 may protrude into the limiting groove 62. A limiting block 321 may be provided at the second end of the driving connector 32, and the limiting block 321 may be accommodated in the limiting groove 62, and the limiting block 321 is located on the side of the limiting step 63 away from the movable end 31.

[0061] A projection plane perpendicular to the first direction can be defined, with the direction from the movable end 31 toward the connecting plate 60 being the positive direction of the first direction, and the direction from the connecting plate 60 toward the movable end 31 being the negative direction of the first direction.

[0062] The orthographic projection of the limiting step 63 on the projection plane can completely or partially overlap with the orthographic projection of the limiting block 321 on the projection plane. Thus, the limiting step 63 can limit the limiting block 321 in the opposite direction of the first direction. When the first driving member 30 drives the second roller 40 to move in the opposite direction of the first direction, that is, when the second roller 40 switches from the second state to the first state, the limiting step 63 can abut against the limiting block 321, thereby driving the connecting member 32 to drive the connecting plate 60 in the opposite direction of the first direction.

[0063] Optionally, the limiting block 321 may be engaged in the limiting groove 62 so that the driving connector 32 and the connecting plate 60 are relatively fixed.

[0064] In addition, the limiting groove 62 can form an opening through at least one side of the connecting plate 60, and the driving connector 32 and the limiting block 321 thereon can enter the limiting groove 62 from the side of the connecting plate 60 through the opening, thereby facilitating the assembly of the connecting plate 60 and the driving connector 32.

[0065] In this embodiment, a driving connector 32 is provided to connect the movable end 31 and the connecting plate 60 . The connection structure is simple, reliable, and easy to assemble.

[0066] In some other optional embodiments, the driving connector 32 is movable relative to the limiting groove 62 along a first direction, and in the first direction, the distance between the limiting step 63 and the bottom surface 622 of the limiting groove 62 is greater than the thickness of the limiting block 321.

[0067] Specifically, the driving connecting member 32 may include a first section 322 and a second section 323. The first section 322 may be screwed to the movable end 31, and the second section 323 may be connected to the end of the first section 322 away from the movable end 31. The end of the second section 323 away from the movable end 31 may be provided with a limit block 321.

[0068] The second section 323 can extend into the limiting groove 62 through the notch 621 of the limiting groove 62 and can move relative to the limiting groove 62 along the first direction. Since the distance between the limiting step 63 and the bottom surface 622 of the limiting groove 62 along the first direction is greater than the thickness of the limiting block 321 in the first direction, when the second section 323 moves along the first direction, it can drive the limiting block 321 to move in the limiting groove 62.

[0069] The projection of the first section 322 along the first direction can overlap with the projection of the limiting step 63 along the first direction, so that the end surface of the first section 322 away from the movable end 31 can abut against the limiting step 63 close to the movable end 31 to limit the connecting plate 60 in the positive direction of the first direction.

[0070] The projection of the second segment 323 along the first direction may be staggered with the projection of the limiting step 63 along the first direction, so that the second segment 323 can freely extend into the limiting groove 62 .

[0071] When the second roller 40 is in the second state, the limit block 321 can be spaced apart from the limit step 63. At this time, the driving connecting member 32 may not apply positive pressure along the first direction to the second roller 40. The second roller 40 can cooperate with the first roller 20 to clamp the sheet 200 under its own gravity. In this way, damage to the sheet 200 caused by excessive clamping force can be avoided, and the stroke of the movable end of the first driving member 30 can be controlled more conveniently.

[0072] According to some other embodiments of the present application, a guide matching portion is provided on the connecting plate 60, and also includes a guide member 70. The guide member 70 is provided on the bracket 10, and the guide member 70 extends along the first direction. The guide member 70 cooperates with the guide matching portion to guide the connecting plate 60 to move along the first direction.

[0073] Specifically, the bracket 10 may be provided with a guide member 70 that can cooperate with a guide mating portion on the connecting plate 60 to guide the connecting plate 60 and the second roller 40 to move in the first direction. The guide member 70 and the guide mating portion can improve the stability of the connecting plate 60 when the second driving member 50 drives the connecting plate 60 to move in the first direction, thereby preventing the second roller 40 from shaking or deflecting.

[0074] In some specific embodiments of the present application, the guide member 70 is a guide rail, and the guide matching portion is a guide groove extending along the first direction. The guide rail is connected to the guide groove to guide the connecting plate 60 to move along the first direction. The structure of the guide roller and the guide groove is simple and easy to assemble.

[0075] Specifically, a slider 61 may be provided on the side of the connecting plate 60 facing the guide rail, and a guide groove may be provided on the side of the slider 61 facing the guide rail. The guide groove extends along a first direction, and a portion of the guide rail may extend into the guide groove. The groove wall of the guide groove may cooperate with the guide rail to limit the connecting plate 60 in the axial direction of the second roller 40, thereby preventing the connecting plate 60 and the second roller 40 from shaking or offsetting during the movement.

[0076] In some other optional embodiments, the guide member 70 can be a guide rod, and the guide matching portion can be a guide hole provided on the connecting plate 60. The connecting plate 60 can be mounted on the guide rod through the guide hole, and the guide rod and the guide hole can cooperate to guide the connecting plate 60 to move along the first direction.

[0077] According to some optional embodiments of the present application, there are two connecting plates 60 , the second roller 40 is located between the two connecting plates 60 , and both ends of the second roller 40 are rotatably connected to the connecting plates 60 .

[0078] Specifically, two connecting plates 60 may be spaced apart and arranged on the bracket 10 along the axis of the second roller 40. Bearing blocks 41 may be provided on each of the two connecting plates 60. The second roller 40 may be located between the two connecting plates 60, and both ends of the second roller 40 may be connected to the two bearing blocks 41 in a one-to-one correspondence. The second driving member 50 may be provided on one of the two connecting plates 60 and connected to the corresponding end of the second roller 40.

[0079] In this embodiment, two connecting plates 60 are provided to connect the second roller 40 , which can improve the stability of the second roller 40 .

[0080] In some specific embodiments of the present application, as shown in FIG1 , there are two first driving members 30 , and the movable ends 31 of the two first driving members 30 are connected to the two connecting plates 60 in a one-to-one correspondence.

[0081] In other words, the number of first driving members 30 and connecting plates 60 is equal, each connecting plate 60 can be driven by a corresponding first driving member 30, and the two first driving members 30 can be located at both ends of the second roller 40. Thus, the driving of the second roller 40 by the first driving member 30 can be more stable, avoiding uneven force at both ends of the second roller 40.

[0082] In some specific embodiments, the speed of the movable end 31 of the first driving member 30 can be controlled so that both ends of the first roller 20 descend at the same speed, thereby preventing one end of the second roller 40 from contacting the sheet 200 first, causing uneven force on the sheet 200, and causing the sheet 200 to accumulate or be damaged.

[0083] According to other embodiments of the present application, there is one first driving member 30, and the movable end 31 is connected to two connecting plates 60. The two connecting plates 60 can be connected together by a connecting structure to form a whole. The first driving member 30 can simultaneously connect and drive the two connecting plates 60 through this connecting structure, so that the two connecting plates 60 can move in the first direction. Reducing the number of first driving members 30 to one reduces the cost of the conveying device 100.

[0084] According to some optional embodiments of the present application, the bracket 10 includes a base 11 , a first bracket 10 and a second bracket 10 .

[0085] The first support 12 is arranged on the base 11, and the first roller 20 is rotatably arranged on the first support 12 around its own axis. One end of the second support 13 is connected to the base 11, and the other end of the second support 13 is provided with a mounting plate 14, and the first driving member 30 is arranged on the mounting plate 14. In the axial direction of the first roller 20, the first support 12 and the second support 13 are spaced apart.

[0086] In other words, the bracket 10 of this embodiment can be primarily composed of a base 11, a first support 12, and a second support 13. The base 11 can serve as a bearing member for supporting the first support 12 and the second support 13. The base 11 can be connected to the frame of the foil production machine to secure the drive device to the foil production machine.

[0087] The first support 12 is used to mount the first roller 20, and the second support 13 is used to mount the first driving member 30, the second driving member 50, and the second roller 40. The first support 12 and the second support 13 can be arranged on the same side of the base 11. Optionally, the second support 13 can extend along the first direction.

[0088] One end of the second support 13 can be fixedly connected to the base 11 , and the other end of the second support 13 can extend beyond the first roller 20 and be provided with a mounting plate 14 . The first driving member 30 can be fixedly mounted on a side of the mounting plate 14 away from the first roller 20 .

[0089] In addition, the first support 12 and the second support 13 can be spaced apart in the axial direction of the first roller 20, thereby the first driving member 30, the connecting plate 60, the guide member 70 and the second driving member 50 can be spaced apart from the first support 12 in the axial direction of the first roller 20, which can make the structure of the conveying device 100 more compact.

[0090] In some specific embodiments, there may be two bases 11, two first supports 12, and two second supports 13, respectively. Each base 11 may be provided with one first support 12 and one second support 13. The two bases 11 may be spaced apart along the axial direction of the first roller 20. The first roller 20 may be located between the two first supports 12. The two ends of the first roller 20 may be connected to the two first supports 12 via bearings, respectively. The second roller 40 may be located between the two second supports 13. The second support 13 may be vertically arranged, with the bottom end of the second support 13 connected to the base 11 and the top end of the second support 13 provided with a mounting plate 14.

[0091] According to some other embodiments of the present application, in the input direction of the sheet 200 , the axis of the first roller 20 is closer to the input sheet 200 than the axis of the second roller 40 .

[0092] Specifically, as shown in Figures 4 and 5 , the sheet 200 has an input direction and an output direction when passing through the conveyor 100. For ease of explanation, the input direction of the sheet 200 can be defined as the third direction. The output direction of the sheet 200 is toward the winding roller, and the cut point c of the sheet 200 is located between the first roller 20 and the winding roller. The output direction and the input direction of the sheet 200 may be at an angle, for example, a right angle. The sheet 200 is conveyed horizontally during input and vertically downward during output.

[0093] In the third direction, the axis of the first roller 20 is spaced apart from the axis of the second roller 40 by a distance s, and the axis of the first roller 20 is closer to the sheet 200 at the upstream position a. Therefore, when the second roller 40 cooperates with the first roller 20 to clamp the sheet 200, the tangent line where the first roller 20 and the second roller 40 meet forms an angle with the sheet 200 being conveyed in the third direction. This allows the sheet 200 to be fed in a different direction. For example, the sheet 200 can be directed downward to facilitate connection to the winding roller below after rewinding.

[0094] The present application also provides a foil machine, which includes a conveying device 100 according to any of the above embodiments. The conveying device 100 can be arranged upstream of the winding roller a to clamp the copper foil and maintain the tension of the upstream copper foil a during roll change.

[0095] Since the conveying device 100 according to the embodiment of the present application has the above-mentioned technical effects, the foil production machine according to the embodiment of the present application also has corresponding technical effects, that is, the roll change can be completed without stopping the machine, and the sheet 200 upstream a of the first roller 20 maintains a stable tension during the roll change process. Compared with the manual pressing of the sheet 200 in the traditional technology, the conveying device 100 of this embodiment reduces the required labor, and the timing of clamping the sheet 200 is more precise, which can avoid the accumulation of the sheet 200 and re-foil threading, which is conducive to saving roll change time and increasing the output of the sheet 200.

[0096] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
