Description

Technical Field

[0001] The utility model relates to the technical field of copper foil processing, in particular to a pretreatment device for a rolled copper foil sheet. Background Art

[0002] Rolled copper foil is a product (usually 4-100 microns thick and usually <800 mm wide) made by repeatedly rolling and annealing high-precision copper strips (usually less than 150 microns thick) using the principle of plastic processing. Its ductility, bending resistance and conductivity are better than those of electrolytic copper foil, and its copper purity is also higher than that of electrolytic copper foil. After fine rolling, the rolled copper foil needs to be trimmed to improve the flatness of the ends of the copper foil. Copper billets are the basic raw materials for the preparation of copper foil; first, the raw copper needs to be melted, and then it is prepared into copper billets through multiple refining, homogenization, casting and other processes. After these process treatments, the composition of the copper billet is purer and the quality is more uniform, which is conducive to the subsequent processing technology. The pretreatment of copper foil is to improve the surface quality of copper foil and enhance its mechanical properties and ductility. This link mainly includes annealing, stacking, cleaning and other steps.

[0003] At present, the following defects exist in the pretreatment of the produced rolled copper foil to clean its surface grease stains: 1. The transported rolled copper foil is passed through a cleaning box filled with cleaning liquid to clean the surface of the rolled copper foil. The rolled copper foil will be quickly discharged after passing through the cleaning liquid, so the cleaning liquid cannot completely rinse the stains on the surface of the rolled copper foil; 2. The cleaning liquid in the cleaning box is generally in a static state. When the rolled copper foil passes through the cleaning liquid, the contact force with the cleaning liquid is small, so the rolled copper foil cannot be completely rinsed; therefore, a pretreatment device for rolled copper foil sheet is proposed. Utility Model Content

[0004] The utility model aims to solve the problems that the existing pretreatment equipment for rolled copper foil sheet cannot wipe the surface of the rolled copper foil and the cleaning liquid is always in a static state and cannot clean the rolled copper foil thoroughly.

[0025] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0026] like Figures 1 to 5As shown, this embodiment proposes a pretreatment device for rolled copper foil sheet material, including a cleaning frame 1 and a conveying assembly arranged on both sides of the top of the cleaning frame 1, and also includes a cleaning assembly and a toggling assembly, the cleaning assembly includes a motor 2 arranged on the outer wall of the cleaning frame 1, a screw 3 arranged at the output end of the motor 2 and extending to the inside of the cleaning frame 1, a moving seat 4 with two threads arranged on the rod walls on both sides of the screw 3, a rotating rod 401 rotatably arranged on the side wall of the moving seat 4, and a cleaning cylinder 5 sleeved on the rod wall of the rotating rod 401, wherein the moving seat 4 is slidably connected to the inner wall of the cleaning frame 1, the two rotating rods 401 are in different horizontal planes, and the toggling assembly is arranged on the inner wall of the cleaning frame 1, and is used to toggle the rolled copper foil transmitted to increase the contact strength between the cleaning cylinder 5 and the rolled copper foil;

[0027] The processed rolled copper foil is transported by the provided conveying assembly and is contacted with the cleaning liquid through the inside of the cleaning frame 1, and the rolled copper foil is passed through the two cleaning cylinders 5, so that the two cleaning cylinders 5 are respectively in contact with the upper and lower surfaces of the rolled copper foil, and the grease stains on the surface of the rolled copper foil can be washed away by the cleaning liquid. At this time, the motor 2 is started to drive the screw rod 3 connected to its output end to rotate forward and reversely, and the screw rod 3 will drive the two cleaning cylinders 5 to move back and forth on the upper and lower surfaces of the rolled copper foil respectively through the two moving seats 4, so that the surface of the rolled copper foil can be wiped and cleaned, which is convenient for cleaning the rolled copper foil thoroughly, and the toggling assembly provided can also continuously toggle the rolled copper foil when cleaning the rolled copper foil, so that the friction between the rolled copper foil and the cleaning cylinder 5 is increased when the rolled copper foil is toggled, thereby further improving the efficiency of the cleaning cylinder 5 in cleaning the rolled copper foil.

[0028] Furthermore, the cleaning assembly also includes a gear 7 fixedly arranged on the end of the rotating rod 401 away from the moving seat 4, and a double-groove tooth plate 6 arranged on the inner wall of the cleaning frame 1 and meshing with the gear 7; when the moving seat 4 drives the cleaning cylinder 5 to move, the cleaning cylinder 5 will rotate along the double-groove tooth plate 6 through the rotating rod 401 and the gear 7, thereby driving the cleaning cylinder 5 to roll against the surface of the rolled copper foil, further facilitating the cleaning cylinder 5 to thoroughly wipe the grease stains on the surface of the rolled copper foil.

[0029] Among them, the movable seat 4 is provided with a threaded hole matching the screw rod 3, and the threaded grooves on the rod walls on both sides of the screw rod 3 rotate in opposite directions; when the motor 2 drives the screw rod 3 to rotate, it can drive the two movable seats 4 to move relative to each other, gradually approaching or gradually moving away, so as to facilitate the uniform wiping and cleaning of the rolled copper foil.

[0030] In addition, a protective shell 11 is provided on the inner wall of the cleaning frame 1, and a slide groove 1101 is provided on the side wall of the protective shell 11 for moving the rotating rod 401; the protective shell 11 can be set to shield the gear 7 and the double-groove tooth plate 6 to prevent stains from getting stuck in the tooth grooves on the gear 7 and the double-groove tooth plate 6 and affecting the operation of the equipment.

[0031] like Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a plurality of stirring blades 8 distributed at equal distances are provided on the rod wall of the rotating rod 401, and a plurality of flow holes 801 are opened on the surface of the stirring blade 8;

[0032] When the cleaning cylinder 5 is rolling, it will also drive the stirring blade 8 to roll inside the cleaning frame 1 through the rotating rod 401 to stir the cleaning liquid. The relative movement of the two cleaning cylinders 5 will cause the stirring blades 8 on the two rotating rods 401 to relatively flip and stir the cleaning liquid, allowing the cleaning liquid to produce convection and increase the flow rate of the cleaning liquid. When the cleaning liquid is pressurized, it will pass through the flow holes 801 on the surface of the stirring blade 8, which can further increase the flow rate of the cleaning liquid, and then increase the contact strength between the cleaning liquid and the rolled copper foil, making it easier to rinse the surface of the rolled copper foil more thoroughly.

[0033] like Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the toggle assembly includes a rotating shaft 9 rotatably arranged on the inner wall of the cleaning frame 1, a torsion spring 901 arranged between the rod walls on both sides of the rotating shaft 9 and the inner wall of the cleaning frame 1, a connecting plate 902 arranged on the rod wall of the rotating shaft 9, a U-shaped rod 903 arranged on the top of the connecting plate 902, a support cylinder 10 rotatably arranged between the two horizontal end surfaces of the U-shaped rod 903, a pull rod 402 arranged at the bottom of a moving seat 4, and a pull rope 1001 arranged between the pull rod 402 and the connecting plate 902;

[0034] When the movable seat 4 moves back and forth, it will continuously pull the connecting plate 902 to flip through the pull rod 402 and the pull rope 1001, and the torsion spring 901 will reverse and reset the flipped connecting plate 902. Therefore, the flipping connecting plate 902 will drive the supporting cylinder 10 on the U-shaped rod 903 to flip back and forth, continuously moving the transported rolled copper foil, causing the rolled copper foil to collide with the cleaning cylinder 5, thereby increasing the contact force between the cleaning cylinder 5 and the rolled copper foil, and further improving the cleaning effect of the rolled copper foil.

[0036] The rolled copper foil is passed through the two conveying drums 13 on both sides of the top of the cleaning frame 1, and then the rolled copper foil passing through the conveying drums 13 is rolled and pulled by the winding device, so that the rolled copper foil can pass through the cleaning liquid inside the cleaning frame 1, which is convenient for cleaning the rolled copper foil.

[0037] The working principle of the utility model is as follows: the processed rolled copper foil is transported through the provided conveying assembly and contacts the cleaning liquid through the inside of the cleaning frame 1, and the rolled copper foil passes through the two cleaning cylinders 5, so that the two cleaning cylinders 5 contact the upper surface and the lower surface of the rolled copper foil respectively, and the grease stains on the surface of the rolled copper foil can be washed away by the cleaning liquid. At this time, the motor 2 is started to drive the screw rod 3 connected to its output end to rotate forward and reversely, and through the cooperation of the provided gear 7 and the double-groove tooth plate 6, the screw rod 3 will drive the two cleaning cylinders 5 to roll back and forth on the upper and lower surfaces of the rolled copper foil respectively through the two moving seats 4, so that the surface of the rolled copper foil can be wiped and cleaned, which is convenient for cleaning the rolled copper foil. The foil is cleaned thoroughly; when the cleaning cylinder 5 is rolling, it will also drive the stirring blade 8 to roll inside the cleaning frame 1 through the rotating rod 401, stir the cleaning liquid, increase the flow rate of the cleaning liquid, and then increase the contact strength between the cleaning liquid and the rolled copper foil, so as to facilitate the surface of the rolled copper foil to be rinsed more thoroughly; and when the movable seat 4 moves back and forth, it will continuously pull the connecting plate 902 to flip through the pull rod 402 and the pull rope 1001, thereby driving the support cylinder 10 on the U-shaped rod 903 to flip back and forth, and continuously move the transported rolled copper foil, so that the rolled copper foil collides with the cleaning cylinder 5, thereby increasing the contact strength between the cleaning cylinder 5 and the rolled copper foil, and further improving the cleaning effect of the rolled copper foil.
