Description

Technical Field

[0001] The utility model relates to the technical field of roller plating equipment, in particular to a roll-to-roll roller plating surface treatment equipment. Background Art

[0002] The patent "Copper foil electroplating equipment" (application number CN202321283922.9) discloses a copper foil electroplating equipment, including multiple plating tanks, each of which includes two frames arranged opposite to each other up and down, and the space between the two frames is used to accommodate copper foil, and the copper foil moves along the arrangement direction of the plating tanks; multiple air-dripping spray pipes, each of which is provided next to an air-dripping spray pipe for spraying liquid on the upper and lower surfaces of the copper foil; multiple vacuum roller assemblies, each of which is provided next to a vacuum roller assembly for fixing the copper foil; the air-dripping spray pipes and vacuum roller assemblies are alternately arranged next to the plating tanks. It is difficult to avoid the problem of wrinkling on the surface of the copper foil during actual use of the above equipment, and a longer production line is required to complete the processing work, which occupies a large space.

[0003] The patent "A roll-to-roll vertical lifting electroplating equipment" (application number CN202310230906.1) discloses a roll-to-roll vertical lifting electroplating equipment, the electroplating section includes an electroplating tank, and two sets of plate heat exchangers are installed inside the electroplating tank, a grabbing mechanism is arranged on the top of the electroplating tank, and the grabbing mechanism is connected to the transmission belt mechanism through an electric telescopic rod, and a guiding mechanism is arranged below the grabbing mechanism for use with it, and a detachable positive titanium mesh mechanism is arranged on both sides of the guiding mechanism, a stirring mechanism is arranged at the bottom of the electroplating tank, and a rectifier is installed on the outside of the electroplating tank, and three-layer circulation filtering mechanisms are arranged on both sides of the electroplating tank. The above equipment has complicated procedures, the copper foil stretching area is too long, which is easy to cause surface defects, and the feasibility is not high.

[0004] Currently, existing roll-to-roll foil plating equipment requires a longer production line and occupies a larger workshop area. As the equipment runs longer, changes in the diameter of the foil roll at the reeling and unreeling point can easily lead to tension fluctuations and other faults when running large rolls of foil. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a roll-to-roll roller plating surface treatment equipment to solve the problems existing in the prior art, such as the large equipment footprint, long operating time, and easy tension fluctuations when running large rolls of foil.

[0006] The technical solution adopted by the utility model to solve the technical problem is: a roll-to-roll roller plating surface treatment equipment, the equipment includes an unwinding unit, a pressing unit, a roller plating unit, a stripping unit, a drying unit and a winding unit; the foil to be plated is wound on the unwinding unit, passes through the pressing unit, the roller plating unit, the stripping unit and the drying unit in sequence, and then is wound on the winding unit; the pressing unit and the stripping unit are in contact with the roller plating unit, and are respectively arranged on both sides of the roller plating unit; the unwinding unit includes an unwinding guide rail and an unwinding roller, and the unwinding roller moves along the unwinding guide rail according to the angle requirement during the unwinding process; the winding unit includes a winding guide rail and a winding roller, and the winding roller moves along the winding guide rail according to the angle requirement during the winding process.

[0007] Furthermore, the clamping unit comprises a clamping guide rail and a clamping roller, and the clamping roller moves along the clamping guide rail according to angle requirements during the clamping process.

[0008] Furthermore, the unwinding roller moves along the unwinding guide rail during operation, keeping the tangent point position between the foil surface to be plated and the pressing roller unchanged, thereby ensuring that the wrap angle of the pressing roller remains unchanged.

[0009] Furthermore, the roller plating unit includes a cathode roller, an anode tank and an anode plate, wherein the anode plate is evenly distributed at the bottom of the anode tank. When the equipment is running, the anode tank contains a treatment liquid, which flows into the anode tank from a liquid inlet at the bottom.

[0010] Furthermore, the stripping unit comprises a stripping guide rail and a stripping roller, and the stripping roller moves along the stripping guide rail according to angle requirements during the stripping process.

[0011] Furthermore, the winding roller moves along the winding guide rail during operation, keeping the tangent point position between the foil surface to be plated and the stripping roller unchanged, thereby ensuring that the wrap angle of the stripping roller remains unchanged.

[0012] Furthermore, the drying unit includes an oven and an air knife.

[0013] The beneficial effects of the utility model are as follows: compared with the prior art, the roll-to-roll roller plating surface treatment equipment provided by the utility model has the following advantages:

[0014] 1) The volume of the equipment of the utility model is much smaller than that of the traditional surface treatment equipment, which shortens the production and processing cycle, and greatly reduces the workshop area occupancy rate while ensuring the electroplating function;

[0015] 2) The roller plating equipment used in the utility model has fewer roller arrangements, fewer foil bends, and the wrap angle does not change during use. The precision error generated at high operating speed is small, and it can adapt to high-speed processing of large-width copper foil;

[0016] 3) With the increase of working time, the wrap angle of reeling of traditional roll-to-roll electroplating equipment increases, while the wrap angle of unwinding decreases, and the angle of foil surface changes with time, which can easily lead to tension adjustment failure. The equipment of the utility model can keep the unwinding and rewinding wrap angles constant during operation through the design of unwinding guide rails and rewinding guide rails, thus avoiding the change of the rewinding and unwinding tension span with time, reducing the equipment failure rate, and increasing the maximum rewinding diameter.
