TECHNICAL FIELD

[0001] The present application relates to the technical field of copper foil milling machine, and particularly relates to an adjustable copper foil milling machine for copper foil surface treatment. BACKGROUND

[0002] Copper foil is a kind of cathode electrolytic material, which is a thin and continuous metal foil deposited on the base layer of a circuit board and serves as a conductor of the PCB. It is easy to adhere to the insulating layer, accept the printed protective layer, and form a circuit pattern after etching.

[0003] Generally, in order to remove the oxide layer on the surface of the copper foil after processing, the copper foil can be milled. For some copper foils with high oxidation degree and thick surface oxide layer, chemical cleaning and milling are required.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention automatically adjusts the pickling time and milling degree of copper foil according to its oxidation level during pickling using an adjustable milling mechanism. This adapts to milling adjustments for different oxidation levels of the copper foil, ensuring the surface treatment effect. Simultaneously, based on the pickling duration and the results of residual acid detection on the copper foil surface after pickling, the subsequent ultrasonic rinsing degree of the copper foil is flexibly adjusted. This achieves automatic adjustment based on the oxidation level of the copper foil surface during milling, guaranteeing the surface treatment effect of the copper foil.

[0020] This invention features an adjustable milling mechanism. During copper foil milling, the pickling time and milling degree of the copper foil in the chemical cleaning tank are automatically adjusted according to the degree of oxidation on the copper foil surface. The rotating movable disc changes the position of the positioning roller to adjust the direction of the copper foil. When the movable disc rotates counterclockwise, the pickling time of the copper foil is shortened, the angle between the copper foil and the vertical line gradually increases, and the milling degree decreases, which is suitable for copper foil with a low degree of oxidation. Conversely, when the movable disc rotates clockwise to change the positioning roller to a horizontal position, it is suitable for copper foil with a high degree of oxidation.

[0021] This invention incorporates an auxiliary rinsing component. After pickling and milling, the copper foil undergoes a preliminary rinse inside the inner rinsing tank, followed by a pH meter in the rinsing tank to detect residual acid on the surface. Based on the test results and the pickling time at the front end, the rinsing degree of the copper foil in the rinsing tank is automatically adjusted. For copper foils with extended pickling time or high oxidation levels, the rinsing time inside the rinsing tank is extended by controlling the rotation of two sets of end plates to both sides. Simultaneously, the copper foil is pressed and spread open under the action of clamping rollers to shorten the distance to the ultrasonic generator vibrator, and the frequency of the external water pump is increased to enhance the water flow impact, thereby improving the rinsing effect of the copper foil inside the rinsing tank.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figures 1-11 An adjustable copper foil milling machine for copper foil surface treatment includes a machine body 1. The machine body 1 includes a chemical cleaning tank 11 and a rinsing tank 12. The chemical cleaning tank 11 is located inside the machine body 1 on the side of the copper foil feed port. The chemical cleaning tank 11 is filled with a chemical cleaning agent (the level of the chemical cleaning agent inside the chemical cleaning tank 11 is shown in the figure). Figure 3 (As shown), dilute hydrochloric acid or similar chemical cleaning agents can be used. The copper foil undergoes chemical cleaning inside the chemical cleaning tank 11 to remove surface oil and oxide layers. The rinsing tank 12 is located inside the machine body 1 on one side of the copper foil discharge point. The rinsing tank 12 is filled with deionized water (the deionized water level inside the rinsing tank 12 is shown in [reference]). Figure 3(As shown), deionized water can be used to rinse copper foil. Ultrasonic generators are fixedly installed at the bottom of the machine body 1, corresponding to the chemical cleaning tank 11 and the rinsing tank 12. The ultrasonic generators are electrically connected to an external controller. During chemical cleaning in the chemical cleaning tank 11 and rinsing in the rinsing tank 12, cavitation effect is used to peel off the deposits on the copper foil surface. An adjustable milling mechanism is installed inside the chemical cleaning tank 11. This mechanism can mill the copper foil after chemical cleaning to help remove the oxide layer on the surface. An inner rinsing tank 121 is installed inside the rinsing tank 12. The copper foil... The inner washing tank 121 allows for initial rinsing when the copper foil passes through it. A drain pipe is fixedly installed inside the inner washing tank 121 to drain the waste liquid. Two redirecting rollers 124 are rotatably installed inside the inner washing tank 121. A positioning sleeve 126 is fixedly installed on the outer side of the inner washing tank 121 near the copper foil discharge point. A pH meter is fixedly installed inside the positioning sleeve 126 to detect the acidity or alkalinity of the copper foil surface as it passes through the positioning sleeve 126. A circulation pipe 122 is fixedly installed inside the rinsing tank 12, and the circulation pipe 122 is connected to an external water pump port. Next, a water outlet pipe 123 is fixedly installed inside the rinsing tank 12. The water inside the rinsing tank 12 flows out through the water outlet pipe 123 to the external water tank. The water in the external water tank is purified by a filtration system. The purified water is then pumped back into the rinsing tank 12. Fixtures 4 are fixedly installed on both sides of the interior of the chemical cleaning tank 11 and the rinsing tank 12. The fixtures 4 are equipped with adjustable tension components, which can adjust the tension of the copper foil according to the actual cleaning situation during the cleaning process. An auxiliary rinsing mechanism is installed inside the rinsing tank 12 to assist in rinsing. The mechanism can assist in improving the rinsing effect of copper foil during rinsing in the rinsing tank 12. By setting an adjustable milling mechanism, the pickling time and milling degree of copper foil can be automatically adjusted according to the oxidation degree of the copper foil to adapt to the surface treatment adjustment of different oxidation degrees of the copper foil, ensuring the surface treatment effect of the copper foil. At the same time, the subsequent ultrasonic rinsing degree of copper foil can be flexibly adjusted according to the pickling time and the residual acid detection results on the surface of copper foil after pickling. This realizes automatic adjustment according to the oxidation degree of the copper foil surface during milling, ensuring the surface treatment effect of the copper foil.

[0036] As an optimized technical solution for an adjustable copper foil milling machine for copper foil surface treatment according to the present invention, the adjustable tensioning assembly includes a fixed frame 4, which is fixedly installed inside a chemical cleaning tank 11 and a rinsing tank 12. An adjustable tensioning roller 41 is rotatably mounted on the fixed frame 4. Both ends of the adjustable tensioning roller 41 are provided with pressure blocks 422, and the adjustable tensioning roller 41 is rotatably mounted between the two pressure blocks 422. Movable cylinders 42 are provided on both sides of the adjustable tensioning roller 41. The adjustable tensioning roller 41 is electrically... The cylinder is driven by an electric cylinder, and the telescopic end of the electric cylinder is fixedly connected to the movable cylinder 42. The movable cylinder 42 moves up and down on the adjustable tension roller 41. The pressure block 422 is movably installed inside the movable cylinder 42 and can move up and down inside the movable cylinder 42. A pressure sensor 421 is fixedly installed inside the movable cylinder 42 and is electrically connected to an external controller. A spring 423 is fixedly installed inside the movable cylinder 42, and one end of the spring 423 is fixedly connected to the pressure block 422. The movable cylinder 42 has a short shaft fixedly installed inside, and the pressure block 422 and spring 423 are all sleeved on the short shaft. With an adjustable tensioning assembly, the degree of acid washing and rinsing of the copper foil in the chemical cleaning tank 11 and rinsing tank 12 is adjusted according to the degree of oxidation of the copper foil. Simultaneously, the adjustable tensioning roller 41 contacts the copper foil, and the pressure sensor 421 and pressure block 422 detect the oxidation. Regarding the tension of copper foil, when milling copper foil with a high degree of oxidation, it is necessary to control the adjustable tension rollers 41 at both ends of the chemical cleaning tank 11 and the rinsing tank 12 to descend, leaving length space for copper foil adjustment. After adjustment, the adjustable tension rollers 41 rise and press against the copper foil to ensure the copper foil is taut. When milling copper foil with a low degree of oxidation, it is also necessary to first control the four sets of adjustable tension rollers 41 to descend, leaving length space for copper foil adjustment. After adjustment, the copper foil is then adjusted and tensioned to ensure smooth milling adjustment.

[0037] As an optimized technical solution for an adjustable copper foil milling machine for copper foil surface treatment according to the present invention, the adjustable milling mechanism includes two movable disks 2, which are rotatably installed inside a chemical cleaning tank 11. One of the movable disks 2 is driven by a servo motor, and the drive shaft of the servo motor is fixedly connected to one of the movable disks 2. The servo motor is electrically connected to an external controller. Two sets of positioning rollers 21 are rotatably installed between the two movable disks 2, with two rollers in each set. A mounting frame 3 is fixedly installed inside the chemical cleaning tank 11. The mounting frame 3 has four movable side plates 353 inside, among which the upper side plate is located on the side plate. A first roller cutter 31 is rotatably mounted between two movable side plates 353 on the lower side. The first roller cutter 31 is driven by a motor, which is fixedly mounted on the movable side plate 353 and electrically connected to an external controller. A second roller cutter 32 is rotatably mounted between the two movable side plates 353 on the lower side. The second roller cutter 32 is driven by a motor, which is fixedly mounted on the movable side plate 353 and electrically connected to an external controller. Two sets of connection detection components are provided on the mounting frame 3. The movable side plates 353 are mounted on the mounting frame 3 via the connection detection components. The connection detection components include a mounting sleeve 35, which is fixedly mounted on the mounting frame 3. The movable side plate 353 is slidably installed inside the mounting sleeve 35 on both sides of the mounting bracket 3. A spring 351 is fixedly installed inside the mounting sleeve 35, with one end of the spring 351 fixedly connected to the movable side plate 353. A pressure sensor 352 is fixedly installed inside the mounting sleeve 35 and is electrically connected to an external controller. A third roller cutter 33 is rotatably installed at the junction of the chemical cleaning tank 11 and the rinsing tank 12. A fourth roller cutter 34 is rotatably installed at the junction of the chemical cleaning tank 11 and the rinsing tank 12. Both the third roller cutter 33 and the fourth roller cutter 34 are connected to the mounting sleeve 35. Driven by a motor, the motor is electrically connected to an external controller. With an adjustable milling mechanism, the pickling time and milling degree of the copper foil in the chemical cleaning tank 11 are automatically adjusted according to the oxidation of the copper foil surface. The movable disk 2 rotates to change the position of the positioning roller 21 to adjust the direction of the copper foil. When the movable disk 2 rotates counterclockwise, the pickling time of the copper foil is shortened, the angle between the copper foil and the vertical line gradually increases, and the milling degree decreases, which is suitable for copper foil with low oxidation degree. Conversely, when the movable disk 2 rotates clockwise to change the positioning roller 21 to a horizontal position, it is suitable for copper foil with high oxidation degree.

[0038] As an optimized technical solution for an adjustable copper foil milling machine for copper foil surface treatment according to the present invention, the auxiliary rinsing mechanism includes drive gears 5. Four drive gears 5 are rotatably installed on both sides inside the rinsing tank 12. One drive gear 5 on one side is driven by a servo motor. The output shaft of the servo motor is fixedly connected to the drive gear 5. The servo motor is electrically connected to an external controller. The two drive gears 5 on each side mesh with each other. End plates 53 are rotatably installed at both ends of the connecting roller 51. End plates 53 are fixedly connected to the corresponding drive gears 5 on both sides. When the drive gears 5 rotate, they can drive the end plates 53 to rotate synchronously. End plates 54 are connected and installed to the corresponding end plates 53 through an installation assembly. The installation assembly includes a guide rail 55, which is fixedly installed on the end plate 53. The guide rail 55 is composed of two arc-shaped rails. End plates 54 are fixedly installed on the end plate 54. A cylindrical slider is mounted inside the guide rail 55. A short cylinder 531 is rotatably mounted on end plate 53. A spring 532 is fixedly mounted inside the short cylinder 531. A connecting shaft 541 is slidably mounted inside the short cylinder 531. One end of the connecting shaft 541 is fixedly connected to one end of the spring 532, and the other end of the connecting shaft 541 is fixedly connected to end plate 54. An auxiliary rinsing assembly is provided. After initial rinsing in the inner rinsing tank 121, the copper foil, after pickling and milling, is tested for residual acid by a pH meter in the positioning sleeve 126. Based on the test results and the pickling time, the rinsing degree of the copper foil in the rinsing tank 12 is automatically adjusted. For copper foil with extended pickling time or high oxidation level, the rinsing time in the rinsing tank 12 is extended by controlling the two sets of end plates 54 to rotate to both sides (see the specific state diagram). Figure 7 As shown), the copper foil is pressed and spread open under the action of the clamping roller 52 to shorten the distance with the ultrasonic generator vibrator. At the same time, the frequency of the external water pump is increased to increase the water flow impact, so as to improve the rinsing effect of the copper foil in the rinsing tank 12.

[0039] In use, the copper foil enters the machine body 1 from the feed side during cleaning. The copper foil undergoes ultrasonic chemical cleaning in the chemical cleaning tank 11 (the level of the chemical cleaning agent in the chemical cleaning tank 11 is shown in the figure), followed by ultrasonic rinsing in the rinsing tank 12 (the level of deionized water in the rinsing tank 12 is shown in the figure). After rinsing, the copper foil is discharged from the discharge side of the machine body 1 (the direction of the copper foil inside the machine body 1 is shown in the figure). Figure 4 (as shown)

[0040] When the copper foil is inside the chemical cleaning tank 11, it passes between the four positioning rollers 21 on the movable disc 2 and extends to the mounting frame 3. Its bottom surface is milled by the first roller cutter 31 and the second roller cutter 32, and then its top surface is milled by the third roller cutter 33 and the fourth roller cutter 34. After milling, the copper foil enters the inner washing tank 121, where the spray head 125 sprays and cleans it. After preliminary cleaning, the copper foil passes inside the positioning sleeve 126 and undergoes intermittent pH value testing by a pH meter. The testing interval is set to 5 seconds per test, and the interval is adjustable. The copper foil after pH testing... The foil passes between two connecting rollers 51 and four clamping rollers 52. At the same time, the water in the rinsing tank 12, together with the ultrasonic generator and water flow guide, washes away the deposits and residual liquid on the surface of the copper foil. During the copper foil cleaning process, the copper foil passes through the surface of the adjustable tension roller 41, which abuts against the bottom surface of the copper foil. The copper foil applies pressure to the adjustable tension roller 41. The pressure value detected and fed back by the pressure sensor 421 and the pressure block 422 reflects the tension of the copper foil. The adjustable tension roller 41 is raised and lowered by the control cylinder to adjust the tension of the copper foil.

[0041] The rotation angle of the movable disk 2 is adjusted according to the degree of oxidation of the copper foil. The higher the degree of oxidation of the copper foil, the thicker the oxide layer on its surface, and the longer the chemical cleaning time required. In the initial state, the four positioning rollers 21 on both sides are in a horizontal state. At this time, the copper foil has the longest contact time with the chemical cleaning agent inside the chemical cleaning tank 11, and the ultrasonic chemical cleaning time is the longest. When the servo motor drives the movable disk 2 to rotate counterclockwise until the positioning roller 21 near the discharge side tilts upward, the contact time between the copper foil and the chemical cleaning agent gradually decreases, and the ultrasonic chemical cleaning time gradually shortens.

[0042] Initially, when the copper foil has been chemically cleaned for the longest time inside the chemical cleaning tank 11, the angle between the copper foil and the vertical line is the smallest. The copper foil contacts the first roller cutter 31 and the second roller cutter 32 and applies pressure to them. The pressure is detected by the spring 351, the pressure sensor 352, and the movable side plate 353. When the copper foil is pressed down, the pressure sensor 352 detects that the pressure value decreases to 0. At this time, the motor starts and drives the first roller cutter 31 and the second roller cutter 32 to rotate to mill the bottom surface of the copper foil. When both the first roller cutter 31 and the second roller cutter 32 start rotating... The third roller cutter 33 and the fourth roller cutter 34 start simultaneously to mill the top surface of the copper foil. When the oxidation degree of the copper foil is low, the movable disk 2 is controlled to rotate counterclockwise to shorten the pickling time. As the movable disk 2 rotates counterclockwise, the pickling time of the movable disk 2 gradually decreases. At the same time, as the movable disk 2 rotates and drives the copper foil to extend upward, the angle between it and the vertical line gradually increases. At this time, the copper foil only applies pressure to the first roller cutter 31. The first roller cutter 31 starts to rotate, and the third roller cutter 33 starts to rotate. The first roller cutter 31 cooperates with the third roller cutter 33 to mill the bottom and top surfaces of the copper foil.

[0043] After the copper foil is milled, it passes through the pH meter in the positioning sleeve 126 to detect residual acid. Then, it passes between the two connecting rollers 51 and the four clamping rollers 52 and is ultrasonically rinsed before being exported. Initially, the two connecting rollers 51 and the four clamping rollers 52 are all in a horizontal state. If there is no residual acid on the surface of the copper foil after rinsing, and the pH meter test result is within the normal range (this range is manually set, usually pH 5.5~7.0), the copper foil passes between the two horizontal connecting rollers 51 and the four clamping rollers 52, is ultrasonically rinsed, and then exported for the next step.

[0044] If residual acid remains on the surface of the copper foil after rinsing, the pH meter reading will be lower than the normal range. In this case, the frequency of the external water pump is increased to enhance the water flow impact force inside the rinsing tank 12. At the same time, the rinsing time of the copper foil inside the rinsing tank 12 is extended. The servo motor drives the drive gear 5 to rotate, and the two drive gears 5 mesh with each other to drive the two end plates 53 to rotate to both sides. As the end plates 53 rotate to both sides, the ultrasonic rinsing time of the copper foil inside the rinsing tank 12 is extended. At the same time, when the end plates 53 rotate, they cause the copper foil to be pressed down and opened, reducing the distance between the copper foil and the vibrator of the ultrasonic generator at the bottom of the rinsing tank 12 (but the control distance is less than the critical distance). The sound wave energy attenuation is small, the cavitation bubble density is high, and the rinsing effect on the surface of the copper foil is improved.

[0045] As the copper foil's extension path changes within the chemical cleaning tank 11 and rinsing tank 12, the adjustable tension roller 41 adjusts its height according to the copper foil's adjustment and tension. The movable cylinder 42 is controlled by an electric cylinder to move up and down, thereby driving the adjustable tension roller 41 to rise and fall. The tension of the copper foil extending from the chemical cleaning tank 11 and rinsing tank 12 is adjusted from both ends of the tank. At the same time, the pressure value fed back by the pressure sensor 421 reflects the tension of the copper foil.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
