Description

Technical Field

[0001] The present application relates to the technical field of copper foil production equipment, and in particular to an ultra-thick copper foil surface treatment machine and a control method thereof. Background Art

[0002] Copper foil is an important industrial material, widely used in the electronics and battery industries. After the copper foil is produced, it needs to be surface treated. The main purpose of the copper foil surface treatment is to enhance the heat resistance and corrosion resistance of the copper foil and improve the electrical and mechanical properties of the copper foil.

[0003] At present, the common copper foil surface treatment steps include pretreatment, roughening, curing, electroplating of dissimilar metals, anti-oxidation, coating and drying. The pretreatment step is to pickle the copper foil surface to remove the surface oxide layer of the copper foil produced by the foil making machine. The above copper foil surface treatment steps are generally carried out in the same copper foil surface treatment machine. During the copper foil is transported in the copper foil surface treatment machine, the copper foil undergoes all surface treatment processes in sequence.

[0004] The existing copper foil surface treatment machine generally includes an unwinding mechanism, a tank processing unit, a drying device and a rewinding mechanism. The unwinding mechanism unwinds the copper foil and transports the unwinded copper foil to the tank processing unit. A number of conveying rollers are also provided in the trough processing unit for realizing the connection and conveying of the copper foil. During the conveying process of the copper foil in the trough processing unit, the trough processing unit performs various surface treatments on the copper foil in sequence; after the copper foil passes through the trough processing unit, the copper foil will enter the drying device, and the drying device will realize the drying of the copper foil; finally, the dried copper foil will be rolled up and unloaded under the action of the rolling mechanism.

[0005] Due to the different usage scenarios of copper foil, the thickness of copper foil is different. When the copper foil surface treatment machine performs surface treatment on thicker copper foil, the unwinding mechanism realizes the unwinding and loading of the copper foil coil. As the copper foil is continuously conveyed, the diameter of the copper foil coil in the unwinding mechanism will continue to decrease, which will cause the conveying angle of the copper foil between the unwinding mechanism and the trough processing unit to change, and the conveying angle will continue to change as the diameter of the copper foil coil decreases, which may cause the copper foil to deviate or jitter during the conveying process, affecting the stability of the conveying, and even affecting the tension of the copper foil, thereby causing the copper foil to be wrinkled or damaged during the conveying process. Summary of the invention

[0006] The present application provides an ultra-thick copper foil surface treatment machine and a control method thereof, the purpose of which is to ensure that the copper foil is fed into the trough treatment unit at a constant angle when the copper foil coil is unwound into the trough treatment unit, thereby improving the stability of the copper foil transportation and reducing the possibility of wrinkles or damage to the copper foil during the transportation process.

[0007] In the first aspect, the present application provides an ultra-thick copper foil surface treatment machine that adopts the following technical solution: A super-thick copper foil surface treatment machine comprises an unwinding mechanism, a trough body treatment unit, a drying device and a rewinding mechanism, wherein the unwinding mechanism, the trough body treatment unit, the drying device and the rewinding mechanism are arranged in sequence; the unwinding mechanism comprises a frame, an unwinding roller and a feeding roller group, wherein the unwinding roller and the feeding roller group are both arranged on the frame, the unwinding roller is coaxially connected with an unwinding driving member for driving the unwinding roller to rotate, the feeding roller group is located between the unwinding roller and the trough body treatment unit, and the feeding roller group is used to introduce the copper foil unwound by the unwinding roller into the trough body treatment unit; an unwinding compensation component is arranged on the frame, the unwinding roller is connected to the unwinding compensation component, the unwinding compensation component is used to drive the unwinding roller to move on the frame, and the driving direction of the unwinding compensation component is perpendicular to the copper foil conveying direction between the unwinding roller and the feeding roller group.

[0008] By adopting the above technical solution, the unwinding mechanism, the tank processing unit, the drying device and the winding mechanism are arranged in sequence, and the unwinding mechanism realizes the unwinding and unwinding functions of the copper foil coil, and then can transport the copper foil to the tank processing unit. After the copper foil enters the tank processing unit, the copper foil is surface treated. After the copper foil surface treatment is completed, the copper foil is transported to the drying device, and the drying device removes the reagent or water remaining on the surface of the copper foil, and finally realizes winding through the winding mechanism. This realizes the whole process of copper foil unwinding, surface treatment, drying and winding, and can realize the function of the copper foil surface treatment machine.

[0009] The unwinding mechanism cooperates with the frame, unwinding roller, unwinding drive and feed roller group. After the copper foil coil is installed on the unwinding roller, the unwinding drive drives the copper foil coil to unwind. At this time, the copper foil is transported to the feed roller group, and then under the action of the feed roller group, the copper foil is introduced into the trough processing unit, which can realize the unwinding and feeding functions of the copper foil coil.

[0010] A reeling compensation assembly is provided on the frame, which drives the reeling roller to move, and the moving direction of the reeling roller is perpendicular to the conveying direction of the copper foil between the reeling roller and the feed roller group. This can drive the reeling roller to move during the reeling process, thereby eliminating or reducing the change in the conveying direction of the copper foil between the reeling roller and the feed roller group caused by the change in the diameter of the copper foil coil.

[0011] By setting the unwinding compensation component, when the unwinding roller rotates to realize the unwinding and feeding process of the copper foil coil, the linear drive drives the unwinding roller to move synchronously. As the diameter of the copper foil coil continues to decrease, the linear drive continuously drives the unwinding roller to move. During this process, the driving direction of the linear drive is always perpendicular to the conveying direction of the copper foil between the unwinding roller and the feeding roller group. This can ensure that the conveying direction of the copper foil between the unwinding roller and the feeding roller group remains unchanged, and ensure that the copper foil is fed into the trough processing unit at a constant angle, thereby improving the stability of the copper foil conveying and reducing the possibility of wrinkles or damage to the copper foil during the conveying process.

[0013] By adopting the above technical solution, the unwinding compensation component includes a linear driver, and the setting of the linear driver realizes the driving function of the unwinding compensation component on the unwinding roller. By setting the rotary driver, the linear driver can be driven to rotate, which can adjust the driving direction of the linear driver to ensure that the driving direction of the linear driver can be perpendicular to the conveying direction of the copper foil between the unwinding roller and the feed roller group. Therefore, when realizing copper foil coils of different specifications, the rotary driver can ensure that the linear driver is always perpendicular to the conveying direction of the copper foil between the unwinding roller and the feed roller group.

[0014] Optionally, the rotary drive includes a supporting table, which is rotatably connected to the frame, the central axis of the supporting table is colinearly arranged with the central axis of the unwinding roller, and a rotating ring gear is coaxially connected to the supporting table; a rotating gear and a rotating motor are arranged on the frame, the rotating gear is meshed with the rotating ring gear, and the driving shaft of the rotating motor is coaxially connected to the rotating gear.

[0015] By adopting the above technical solution, under the drive of the rotary motor, the rotary gear and the rotary gear ring are transmitted, thereby driving the supporting circular table to rotate, which can realize the high-precision rotary drive function of the rotary driver.

[0016] Optionally, the linear drive includes a connecting seat, a direct-drive rack, a direct-drive gear and a transmission assembly, one end of the unwinding roller is rotatably connected to the connecting seat, the direct-drive rack is arranged on the rotary driver, the length direction of the direct-drive rack is perpendicular to the conveying direction of the copper foil between the unwinding roller and the feeding roller group, and the connecting seat is slidingly connected to the direct-drive rack along the length direction of the direct-drive rack; the direct-drive gear is rotatably connected to the connecting seat, and the direct-drive gear is meshed with the direct-drive rack; the transmission assembly is coaxially connected to the direct-drive gear, and the transmission assembly is used to drive the direct-drive gear to rotate.

[0017] By adopting the above technical solution, through the cooperation of the direct drive gear and the direct drive rack, under the action of the transmission assembly, the direct drive gear rotates, while the direct drive rack is fixed, and the direct drive gear can move along the length direction of the direct drive rack, thereby enabling the connecting seat and the unwinding roller to move along the length direction of the direct drive rack. This can realize the function of the linear drive.

[0018] Optionally, a plurality of sliding support members are provided on the rotary driver, and the sliding support members include an auxiliary slide rail and a slide table. The auxiliary slide rail is provided on the rotary driver, and the length direction of the auxiliary slide rail is provided along the length direction of the direct drive rack. The slide table is provided on the connecting seat, and the slide table is slidably connected to the auxiliary slide rail.

[0019] By adopting the above technical solution, the sliding support member can assist the sliding of the connecting seat through the matching arrangement of the auxiliary slide rail and the slide table, while improving the stability of the connection between the rotary drive and the linear drive.

[0020] Optionally, the transmission assembly includes a housing, an input shaft, a first gear, a second gear and an output shaft, the input shaft and the output shaft are both rotatably connected to the housing, the first gear and the second gear are both located in the housing, the first gear is coaxially connected to the input shaft, the second gear is coaxially connected to the output shaft, and the first gear is meshed with the second gear; the input shaft is coaxially connected to the unwinding roller or the unwinding drive member, and the output shaft is coaxially connected to the direct drive gear.

[0021] By adopting the above technical solution, the transmission component cooperates with the input shaft, the first gear, the second gear and the output shaft, the input shaft is coaxially connected to the unwinding roller or the unwinding driving member, and the output shaft is coaxially connected to the direct-drive gear. Therefore, when the unwinding driving member drives the unwinding roller to rotate, the input shaft rotates, and then under the transmission of the first gear and the second gear, the output shaft rotates synchronously. At this time, the output shaft drives the direct-drive gear to rotate, so the transmission component can realize the transmission function of the unwinding roller and the direct-drive gear, so that when the unwinding roller rotates, the linear drive can synchronously drive the unwinding roller to move.

[0022] Optionally, the shell includes a first half shell and a second half shell, the first half shell and the second half shell are arranged opposite to each other along the axial direction of the input shaft, the second half shell is sleeved on the outside of the first half shell, and the first half shell is slidingly connected to the second half shell along the axial direction of the input shaft, a transmission space is formed between the first half shell and the second half shell, and the first gear and the second gear are both located in the transmission space; the input shaft is rotationally connected to the first half shell and the second half shell, and the input shaft is slidingly connected to the first half shell along its own axial direction; the output shaft is rotationally connected to the first half shell and the second half shell, and the output shaft is slidingly connected to the second half shell along its own axial direction.

[0023] By adopting the above technical solution, the first half shell and the second half shell are slidably connected to each other, and the input shaft is slidably connected to the first half shell, and the output shaft is slidably connected to the second half shell, which makes it possible for the first half shell and the second half shell to move closer to or away from each other, thereby facilitating the disassembly and assembly of the shell.

[0024] Optionally, there are multiple first gears and multiple second gears, and the multiple first gears are spaced apart in sequence along their own axial direction, and the multiple second gears are spaced apart in sequence along their own axial direction. The first gears and the second gears are arranged in one-to-one correspondence, and the first gear can mesh with the corresponding second gear; when there is one first gear meshing with the corresponding second gear, all other first gears are separated from the corresponding second gears.

[0025] By adopting the above technical solution, since the first half shell and the second half shell can slide relative to each other, during the process of relative sliding between the first half shell and the second half shell, the first gear can slide along its own axis in sequence through all the second gears, and during this process, the first gear only meshes with the corresponding second gear.

[0026] Therefore, when the first half shell and the second half shell are relatively slid, different first gears can be selected to mesh with the corresponding second gears, so that the transmission component has different transmission ratios, which can improve the application range of the transmission component and enable the unwinding roller to unwind copper foil coils of different specifications.

[0027] Optionally, a first support tube is provided on the first half shell, the first support tube is coaxially arranged with the input shaft, the first support tube is communicated with the transmission space, the input shaft and the first support tube are plug-fitted and slidably connected, and the input shaft and the first support tube are rotatably connected; a second support tube is provided on the second half shell, the second support tube is coaxially arranged with the output shaft, the second support tube is communicated with the transmission space, the output shaft and the second support tube are plug-fitted and slidably connected, and the output shaft and the second support tube are rotatably connected.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0044] An ultra-thick copper foil surface treatment machine, reference Figure 1 , including an unwinding mechanism 1, a trough processing unit 2, a drying device 3 and a rewinding mechanism 4, which are arranged in sequence and spaced apart in the horizontal direction.

[0045] The unwinding mechanism 1 realizes the unwinding and unwinding functions of the copper foil coil, and can then convey the copper foil to the tank processing unit 2. The tank processing unit 2 includes a plurality of processing tanks, which are arranged in sequence in the horizontal direction, and each processing tank is provided with a conveying roller group. After the copper foil enters the tank processing unit 2, with the cooperation of the plurality of conveying roller groups, the copper foil passes through all the processing tanks in sequence. During this process, the copper foil is surface treated. After the surface treatment of the copper foil is completed, the copper foil is conveyed to the drying device 3, and the drying device 3 removes the reagents or water remaining on the surface of the copper foil. Finally, the copper foil is wound up by the winding mechanism 4. This realizes the whole process of copper foil unwinding, surface treatment, drying and winding.

[0046] Reference Figure 1 and Figure 2 The unwinding mechanism 1 comprises a frame 11, an unwinding roller 12 and a feed roller group 13, and the feed roller group 13 and the feed roller group 13 are both arranged on the frame 11. Along the conveying direction of the copper foil, the feed roller group 13 is located between the unwinding roller 12 and the tank processing unit 2.

[0047] Reference Figure 2 and Figure 3 The two ends of the unwinding roller 12 are rotatably connected to the frame 11, and the unwinding roller 12 is coaxially connected with an unwinding driving member 14. When the copper foil coil is sleeved on the unwinding roller 12, the unwinding driving member 14 drives the unwinding roller 12 to rotate, thereby realizing the unwinding and feeding functions of the copper foil coil. After the copper foil is unwound, it is conveyed to the feeding roller group 13, and under the conveyance of the feeding roller group 13, the copper foil can be stably conveyed to the tank processing unit 2.

[0048] Reference Figure 2 and Figure 3 An unwinding compensation assembly 15 is provided between both ends of the unwinding roller 12 and the frame 11. The unwinding compensation assembly 15 includes a linear driver 151 and a rotary driver 152. The rotary driver 152 is on the frame 11, and the central axis of the rotary driver 152 is collinear with the central axis of the unwinding roller 12; the linear driver 151 is provided on the rotary driver 152, and the linear driver 151 is connected to the rotary driver 152 along the middle of its own length direction; one end of the unwinding roller 12 is rotationally connected to the corresponding linear driver 151.

[0049] Driven by the rotary driver 152, the linear driver 151 rotates, which can adjust the position of the linear driver 151 so that the length direction of the linear driver 151 is perpendicular to the conveying direction of the copper foil between the unwinding roller 12 and the feed roller group 13. After the rotary driver 152 is adjusted, driven by the linear driver 151, the moving direction of the unwinding roller 12 is perpendicular to the conveying direction of the copper foil between the unwinding roller 12 and the feed roller group 13. In the process of unwinding the copper foil coil by the unwinding roller 12, the unwinding roller 12 is driven to move by the linear driver 151, which can ensure that the conveying direction of the copper foil between the unwinding roller 12 and the feed roller group 13 remains unchanged, so that the copper foil is conveyed to the feed roller group 13 at a fixed angle, thereby ensuring that the copper foil is loaded at a constant angle.

[0050] Reference Figure 2 and Figure 3The rotary driver 152 includes a support truncated table 1521, a rotary gear ring 1522, a rotary gear 1523 and a rotary motor 1524, and the support truncated table 1521, the rotary gear ring 1522, the rotary gear 1523 and the rotary motor 1524 are all arranged on the frame 11. The central axis of the support truncated table 1521 is arranged colinearly with the central axis of the unwinding roller 12, the support truncated table 1521 is rotatably connected to the frame 11 through a slewing bearing, the support truncated table 1521 is coaxially connected to the rotary gear ring 1522, the rotary gear 1523 is meshed with the rotary gear ring 1522, and the driving shaft of the rotary motor 1524 is coaxially connected to the rotary gear 1523. In this embodiment, the rotary motor 1524 adopts a servo motor, and the rotary motor 1524 is fixed to the frame 11, and the rotary gear 1523 is rotatably connected to the frame 11.

[0051] Driven by the rotary motor 1524, the rotary gear 1523 drives the rotary gear ring 1522 to rotate, which can drive the supporting truncated table 1521 to rotate synchronously. Such a structure is sufficient to realize the high-precision rotary driving function of the rotary driver 152.

[0052] Reference Figure 2 and Figure 3 , the initial position of the unwinding roller 12 is that the central axis of the supporting truncated table 1521 is collinear with the central axis of the unwinding roller 12. Since the diameter, thickness and initial position of the unwinding roller 12 are fixed, before the unwinding roller 12 is unwound, the conveying direction of the copper foil between the unwinding roller 12 and the feeding roller group 13 in the initial stage of unwinding can be determined according to the diameter and thickness of the copper foil coil to be installed. In this way, the driving direction of the linear driver 151 can be determined according to the conveying direction of the copper foil between the unwinding roller 12 and the feeding roller group 13. At this time, the linear driver 151 is driven to rotate by the rotary driver 152, so that the linear driver 151 rotates to the required position. Then, after the corresponding copper foil coil is installed on the unwinding roller 12, the driving direction of the linear driver 151 is perpendicular to the conveying direction of the copper foil between the unwinding roller 12 and the feeding roller group 13.

[0053] In this embodiment, refer to Figure 3 and Figure 4 Two sliding supports 153 are arranged on the supporting truncated table 1521. The sliding supports 153 include an auxiliary slide rail 1532 and a slide table 1531. The length direction of the auxiliary slide rail 1532 is arranged along the driving direction of the linear driver 151. The two auxiliary slide rails 1532 are arranged in parallel and at intervals, and the linear driver 151 is located between the two auxiliary slide rails 1532. The slide table 1531 is arranged on the unwinding roller 12, and the slide table 1531 is slidably connected to the auxiliary slide rail 1532.

[0054] The coordinated arrangement of the two sliding supports 153 can improve the stability of the linear drive 151 in driving the unwinding roller 12 to move.

[0055] Reference Figure 3 and Figure 4 The linear drive 151 includes a connecting seat 1511, the length direction of the connecting seat 1511 is arranged along the spacing direction of the two auxiliary slide rails 1532, the connecting seat 1511 is located between the slide 1531 and the unwinding roller 12 along the axial direction of the unwinding roller 12, and one side of the connecting seat 1511 is fixedly connected to the two slides 1531, and the other side is rotatably connected to the unwinding roller 12. The connecting seat 1511 realizes the connection between the unwinding roller 12 and the two slides 1531.

[0056] Reference Figure 3 and Figure 4 The linear drive 151 includes a direct-drive rack 1512 and a direct-drive gear 1513, both of which are located between the connecting seat 1511 and the supporting truncated table 1521, the direct-drive rack 1512 is connected to the supporting truncated table 1521, the length direction of the direct-drive rack 1512 is arranged along the length direction of the auxiliary slide rail 1532, the direct-drive rack 1512 is located between the two auxiliary slide rails 1532, the direct-drive gear 1513 is meshed with the direct-drive rack 1512, the direct-drive gear 1513 is rotationally connected to the connecting seat 1511, and the direct-drive gear 1513 is transmission-connected to the unwinding roller 12.

[0057] Reference Figure 3 and Figure 4 When the unwinding driving member 14 drives the unwinding roller 12 to rotate, the unwinding roller 12 drives the direct drive gear 1513 to rotate synchronously. At this time, the direct drive gear 1513 cooperates with the direct drive rack 1512, which enables the direct drive gear 1513, the connecting seat 1511 and the unwinding roller 12 to move along the length direction of the direct drive rack 1512. This can meet the function of the linear drive 151.

[0058] In this embodiment, refer to Figure 4 and Figure 5A transmission assembly 16 is provided between the unwinding roller 12 and the direct drive gear 1513. The transmission assembly 16 includes a housing 161, an input shaft 162, a first gear 163, a second gear 164 and an output shaft 165. The input shaft 162 and the output shaft 165 are both rotatably connected to the housing 161. The first gear 163 and the second gear 164 are both located in the housing 161. The first gear 163 is coaxially connected to the input shaft 162, and the second gear 164 is coaxially connected to the output shaft 165. The first gear 163 is meshed with the second gear 164. Both ends of the input shaft 162 extend out of the housing 161. One end of the input shaft 162 is coaxially connected to the unwinding roller 12, and the other end is rotatably connected to the connecting seat 1511. Both ends of the output shaft 165 also extend out of the housing 161. A rotating hole is provided on the connecting seat 1511. The output shaft 165 is plugged into the rotating hole, and the direct drive gear 1513 is coaxially connected to the output shaft 165.

[0059] Since the input shaft 162 is coaxially connected to one end of the unwinding roller 12, when the unwinding roller 12 rotates to unwind the copper foil, the unwinding roller 12 rotates synchronously with the driving input shaft 162, and then under the action of the input shaft 162, the first gear 163, the second gear 164 and the output shaft 165, the output shaft 165 drives the direct drive gear 1513 to connect. This can realize the transmission function of the unwinding roller 12 and the direct drive gear 1513, so that the linear drive 151 can work synchronously with the unwinding roller 12.

[0060] In this embodiment, refer to Figure 3 and Figure 5 Transmission components 16 are provided at both ends of the unwinding roller 12, one transmission component 16 is located between the unwinding roller 12 and the corresponding connecting seat 1511, and the other transmission component 16 is located between the unwinding roller 12 and the unwinding driving member 14.

[0062] Reference Figure 5 and Figure 6The housing 161 includes a first half shell 1611 and a second half shell 1612. The first half shell 1611 and the second half shell 1612 are arranged opposite to each other along the axial direction of the input shaft 162. The first half shell 1611 and the second half shell 1612 are plug-fitted. The second half shell 1612 is sleeved on the outside of the first half shell 1611. The second half shell 1612 is slidably connected to the first half shell 1611 along the axial direction of the input shaft 162. A transmission space 1613 is formed between the second half shell 1612 and the second half shell 1612, and the first gear 163 and the second gear 164 are both located in the transmission space 1613.

[0063] When the first half shell 1611 and the second half shell 1612 slide relative to each other, the size of the transmission space 1613 can be expanded or reduced, which also facilitates the disassembly and installation of the shell 161.

[0064] Reference Figure 5 and Figure 6 A first support tube 1614 is provided on the side of the first half shell 1611 facing away from the second half shell 1612. The first support tube 1614 is coaxially arranged with the input shaft 162, and the first support tube 1614 is connected to the transmission space 1613. One end of the input shaft 162 is rotatably connected to the second half shell 1612, and the other end is plugged into the first support tube 1614.

The second support tube 1615 is coaxially arranged with the output shaft 165, and the second support tube 1615 is connected to the transmission space 1613. One end of the output shaft 165 is rotatably connected to the second half shell 1612, and the other end is plug-fitted with the second support tube 1615.

When the first half shell 1611 and the second half shell 1612 slide relative to each other, the output shaft 165 and the second support tube 1615 slide and withdraw. Similarly, the input shaft 162 and the first support tube 1614 slide and withdraw, thereby ensuring that the first half shell 1611 and the second half shell 1612 can be disassembled smoothly.

[0066] Reference Figure 6, a plurality of first gears 163 and a plurality of second gears 164 are provided, and the plurality of first gears 163 and the plurality of second gears 164 are both located in the transmission space 1613, and the plurality of first gears 163 are sequentially spaced along the axial direction of the input shaft 162, and the plurality of second gears 164 are sequentially spaced along the axial direction of the output shaft 165. The first gears 163 and the second gears 164 are arranged one by one in correspondence, and the first gears 163 can mesh with the corresponding second gears 164, and when there is one first gear 163 meshing with the corresponding second gear 164, all the remaining first gears 163 are separated from the corresponding second gears 164.

[0067] When the first half shell 1611 and the second half shell 1612 slide against each other, different first gears 163 can be selected to mesh with the corresponding second gears 164, which enables the transmission assembly 16 to select different transmission ratios. This enables the corresponding transmission ratio to be selected according to the thickness of the copper foil coil to be unwound, ensuring that the driving speed of the unwinding roller 12 by the linear drive 151 can match the thickness of the copper foil, so that the copper foil conveying direction is always perpendicular to the driving direction of the linear drive 151.

[0068] Reference Figure 5 and Figure 7 The housing 161 is provided with a positioning mounting member 166, which includes a mounting bolt 1661. The second half shell 1612 is provided with a fixing hole 1662, and the first half shell 1611 is provided with a plurality of screw holes 1663, which are sequentially spaced along the axial direction of the input shaft 162.

[0069] During the relative sliding process between the first half shell 1611 and the second half shell 1612, a plurality of screw holes 1663 can be connected with the corresponding fixing holes 1662 in sequence. When the corresponding screw holes 1663 are connected with the corresponding fixing holes 1662, the mounting bolts 1661 are fixed, thereby fixing the first half shell 1611 and the second half shell 1612 and ensuring the stability of the shell 161.

[0070] In this embodiment, refer to Figure 6 and Figure 7 , a plurality of screw holes 1663 are arranged one by one with a plurality of first gears 163, and when the fixing hole 1662 is coaxially connected with the corresponding screw hole 1663, the corresponding first gear 163 is meshed with the corresponding second gear 164. The cooperation between the screw hole 1663 and the fixing hole 1662 can also serve as an identification that the transmission assembly 16 is in a corresponding transmission ratio.

[0071] In this embodiment, refer to Figure 5and Figure 7 A plurality of positioning mounting members 166 are provided between the first half shell 1611 and the second half shell 1612 , so that a plurality of mounting bolts 1661 can be installed between the first half shell 1611 and the second half shell 1612 , thereby improving the stability of the shell 161 .

[0072] Reference Figure 2 and Figure 8 The feed roller group 13 includes a wheel frame 131, a driving roller 132 and a driven roller 133. The wheel frame 131 is arranged on the frame 11, and the driving roller 132 and the driven roller 133 are arranged parallel to the unwinding roller 12. Both ends of the driving roller 132 and the driven roller 133 are rotatably connected to the wheel frame 131. The driving roller 132 is coaxially connected with a driving driving member 135. The driving roller 132 and the driven roller 133 are arranged at intervals in the vertical direction to form a conveying gap 134. When the unwinding copper foil unwound by the unwinding mechanism 1 is conveyed to the conveying gap 134, under the drive of the driving driving member 135, the driving roller 132 and the driven roller 133 cooperate to stably convey the copper foil to the tank processing unit 2.

[0073] Reference Figure 8 A fine-tuning driving member 136 is provided between the active roller 132 and the driven roller 133, and both ends of the active roller 132 are slidably connected to the wheel frame 131 in the vertical direction. A fine-tuning driving member 136 is provided on the wheel frame 131. In this embodiment, the fine-tuning driving member 136 adopts a manual fine-tuning bolt or a linear module driven by a motor. The driving end of the fine-tuning driving member 136 is connected to the active roller 132. Under the drive of the fine-tuning driving member 136, the position of the active roller 132 can be adjusted, and then the conveying gap 134 can be adjusted, so that the feed roller group 13 can adapt to the conveying of copper foils of different thicknesses.

[0074] In this embodiment, refer to Figure 1 and Figure 2 , the unwinding mechanism 1 is the same as the rewinding mechanism 4, the rewinding mechanism 4 includes a rewinding roller, a rewinding compensation assembly and a discharging roller group, the rewinding roller has the same structure as the unwinding roller 12, the rewinding compensation assembly has the same structure as the unwinding compensation assembly 15, and the discharging roller group has the same structure as the feeding roller group 13, so the rewinding mechanism 4 has the same function as the unwinding mechanism 1. This allows the copper foil to be transported to the tank treatment unit 2 at a constant angle during the operation of the copper foil surface treatment machine, and after the copper foil is surface treated, the copper foil can be rewound by the rewinding mechanism 4 at a constant angle. Since the feeding and discharging angles of the copper foil are always constant, this can reduce the deviation or jitter that may occur during the copper foil transportation process.

[0075] The implementation principle of the embodiment of the present application is as follows: before using the copper foil surface treatment machine, the unwinding roller 12 is reset, and the diameter and thickness of the copper foil coil to be installed are measured. According to the diameter and thickness data of the copper foil coil, the conveying direction of the copper foil between the unwinding roller 12 and the feed roller group 13 in the initial stage of unwinding is simulated. According to the simulation results, the rotary driver 152 drives the linear driver 151 to rotate to the corresponding position, so that the driving direction of the linear driver 151 is perpendicular to the simulated conveying direction of the copper foil between the unwinding roller 12 and the feed roller group 13.

[0076] When using the copper foil surface treatment machine, during the unwinding process of the unwinding roller 12, as the unwinding roller 12 rotates, the unwinding roller 12 moves synchronously under the drive of the linear driver 151, which makes the copper foil conveying direction between the unwinding roller 12 and the feeding roller group 13 remain unchanged, thereby making the copper foil stably conveyed to the trough body treatment unit 2, and the copper foil is surface treated in the trough body treatment unit 2. After the surface treatment is completed, the copper foil is conveyed to the drying device 3 to achieve drying of the copper foil, and finally the copper foil is rolled up by the winding mechanism 4 at a fixed angle.

[0077] When replacing copper foil coils of different thicknesses, according to the thickness of the copper foil coils at this time, the transmission assembly 16 is disassembled, and the first half shell 1611 and the second half shell 1612 are slidably adjusted, and the corresponding first gear 163 and the second gear 164 are selected to mesh, thereby changing the transmission ratio of the transmission assembly 16, and then the transmission assembly 16 is reinstalled. At the same time, the width of the conveying gap 134 between the active roller 132 and the driven roller 133 in the feed roller group 13 and the discharge roller group is adjusted according to the thickness of the copper foil coils. Finally, the above steps are repeated, so that the surface treatment of copper foil coils of different thicknesses can be achieved.

[0078] This embodiment also discloses a control method for an ultra-thick copper foil surface treatment machine, comprising the following steps: S1, the unwinding mechanism 1 and the rewinding mechanism 4 are pre-adjusted.

[0079] Specifically, the unwinding mechanism 1 has the same structure as the rewinding mechanism 4, and the pre-adjustment method is also the same. This embodiment takes the pre-adjustment steps of the unwinding mechanism 1 as an example for explanation, and the pre-adjustment steps of the unwinding mechanism 1 are as follows: S11, linear drive 151 position adjustment.
