Description

A roll-to-roll electroplating immersion solution cutting device Technical Field

[0001] This utility model relates to the field of electroplating technology, and more specifically, to a roll-to-roll electroplating immersion liquid cutting device. Background Technology

[0002] With the rapid development of industries such as electronics, semiconductors, and solar energy, electroplating technology plays an increasingly important role in the manufacturing process, especially in roll-to-roll electroplating, where the uniformity and precision of the plating solution are crucial to the quality of the final product. To improve the efficiency and consistency of the electroplating process, roll-to-roll electroplating immersion devices are widely used in large-scale production. These devices typically require the stable transport of the products to be electroplated via a chemical bath and conveyor rollers, while simultaneously immersing them in the plating solution. Precise control of the plating solution and stable tension of the products to be electroplated are key factors in ensuring electroplating quality.

[0003] Existing roll-to-roll electroplating equipment generally uses conveyor rollers to feed the products to be electroplated into the electroplating solution. In practical applications, due to the limited precision of the rollers, the existing equipment is prone to vertical jumping during the rotation and conveying process, which makes it impossible for the rollers to stably adhere to the surface of the products to be electroplated. Especially during high-speed conveying, there is often an excessive amount of chemical carried out, which not only affects the efficiency of the electroplating solution, but also easily causes waste of the electroplating solution and environmental pollution. At the same time, uneven liquid distribution also directly affects the uniformity and quality of electroplating.

[0004] Therefore, there is a need to provide a roll-to-roll electroplating immersion solution cutting device to solve the problem of excessive chemical carry-out in existing electroplating devices. Summary of the Invention

[0005] The main objective of this invention is to provide a roll-to-roll electroplating immersion liquid cutting device, which aims to solve the technical problems mentioned in the background art.

[0006] The present invention adopts the following technical solution:

[0007] A roll-to-roll electroplating immersion solution cutting device, comprising:

[0008] A first medicine tank and a second medicine tank, with an isolation tank provided between the first medicine tank and the second medicine tank;

[0009] The conveyor roller assembly includes two rotating rollers arranged side by side in the vertical direction, with a gap between the two rotating rollers for the electroplating product to pass through. Several horizontally distributed conveyor roller assemblies are provided in both the first and second chemical tanks.

[0010] A floating liquid cutting assembly includes a tension adjusting roller disposed at the bottom end of the product to be electroplated, and liquid cutting drive components are connected to opposite ends of the tension adjusting roller. The liquid cutting drive components are used to drive the tension adjusting roller to move up and down to maintain a constant tension on the product to be electroplated.

[0011] Furthermore, the first medicine tank, the second medicine tank, and the isolation tank are all provided with conveying ports, and the conveying ports are correspondingly arranged with the conveying roller group.

[0012] Furthermore, a conveyor frame is inserted through the conveyor opening, and several mounting slots are opened on the upper end surface of the conveyor frame, with the conveyor roller assembly disposed in the mounting slots.

[0013] Furthermore, the floating liquid cutting assembly also includes a floating track arranged in a vertical direction, the floating track being disposed on the inner side of the isolation groove, and a floating slider being rotatably connected to the outer side of the tension adjusting roller, the floating slider being slidably connected to the floating track.

[0014] Furthermore, a lifting seat is provided on the outside of the isolation groove, and a lifting frame is slidably connected to the lifting seat. The upper end face of the lifting frame is connected to the tension adjusting roller, and the bottom end of the lifting frame is connected to the driving end of the liquid cutting drive.

[0015] Furthermore, the liquid cutting drive is disposed at the bottom end of the isolation groove, the output shaft of the liquid cutting drive is connected to a gear, and the bottom end of the lifting frame is connected to a rack. The gear meshes with the rack to drive the lifting frame to move up and down.

[0016] Furthermore, the bottom of the first medicine tank is provided with a funnel-shaped first recess, and the bottom of the second medicine tank is provided with a funnel-shaped second recess. Both the bottom ends of the first and second recesses are provided with drainage holes.

[0018] Beneficial effects:

[0019] This invention provides a roll-to-roll electroplating immersion liquid cutting device. A first and second chemical tank, along with an isolation tank between them, form an electroplating space with effective liquid control. A conveyor roller assembly is positioned within the chemical tank. Two parallel rotating rollers, with a gap between them, allow the workpiece to be electroplated to be conveyed into the electroplating solution, ensuring stable transport and preventing chemical overflow or uneven coating due to uneven transport. The tension regulating roller in the floating liquid cutting assembly, in conjunction with the liquid cutting drive, controls the tension of the workpiece by adjusting the roller's movement. This maintains a constant tension on the workpiece, ensuring that the amount of chemical carried out during transport remains within a predetermined range, preventing excessive chemical carry-out. The liquid cutting drive precisely adjusts the tension regulating roller's movement, achieving precise control of the electroplating solution, preventing waste, ensuring efficient use of the solution, and effectively improving the electroplating quality of the workpiece.

[0025] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] Referring to Figures 1 to 3, this utility model proposes a roll-to-roll electroplating immersion liquid cutting device, including: a first chemical tank 1 and a second chemical tank 2, with an isolation tank 3 provided between the first chemical tank 1 and the second chemical tank 2.

[0030] The conveyor roller group 4 includes two rotating rollers 41 arranged in parallel in the vertical direction, and a gap is provided between the two rotating rollers 41 for the product to be electroplated to pass through. Several horizontally distributed conveyor roller groups 4 are provided in the first chemical tank 1 and the second chemical tank 2.

[0031] The floating liquid cutting assembly 5 includes a tension adjusting roller 501, which is disposed at the bottom end of the product to be electroplated. Liquid cutting drive components 502 are connected to the opposite ends of the tension adjusting roller 501. The liquid cutting drive components 502 are used to drive the tension adjusting roller 501 to rise and fall, so as to keep the tension of the product to be electroplated constant.

[0032] In the above embodiments, a highly efficient liquid-controlled electroplating space is formed by the structure of the first chemical tank 1, the second chemical tank 2, and the isolation tank 3 between them. The isolation tank 3 effectively separates the different chemical tanks, preventing cross-contamination of the electroplating solution, while ensuring that the electroplating solution in each tank remains stable, thus guaranteeing consistency during the electroplating process. Several horizontally distributed conveyor roller groups 4 are provided in the chemical tanks. Each roller group consists of two vertically arranged rotating rollers 41 with gaps between them. The products to be electroplated can smoothly pass through these gaps and enter the chemical tank for immersion, ensuring stable delivery to the electroplating solution. This avoids problems such as chemical overflow or uneven coating caused by improper roller group or chemical tank design, ensuring that the electroplating solution can uniformly cover the surface of each product, thereby improving the uniformity and quality of electroplating.

[0033] To further optimize the control of the plating solution during electroplating, the tension regulating roller 501 and the liquid cutting drive 502 in the floating liquid cutting assembly 5 work together. The tension regulating roller 501 is located at the bottom of the product to be electroplated, making rolling contact with it, and is connected to the liquid cutting drive 502. The liquid cutting drive 502 can precisely control the raising and lowering of the tension regulating roller 501, ensuring that the product to be electroplated maintains a constant tension state during the conveying process. Through this control, the tension regulating roller 501 can adjust the tension of the product to be electroplated, avoiding excessive carry-over of plating solution during conveying and reducing waste of the electroplating solution. At the same time, it can also ensure the stability of the tension of the product to be electroplated when immersed in the liquid, further improving the electroplating quality, making the electroplated film on the surface of each product more uniform, and improving the overall production efficiency and the quality of the electroplated products.

[0034] Referring to Figures 1 and 3, in one embodiment, the first medicine tank 1, the second medicine tank 2, and the isolation tank 3 are all provided with conveying ports 6, and the conveying ports 6 are correspondingly arranged with the conveying roller group 4.

[0035] In the above embodiments, the first chemical tank 1, the second chemical tank 2, and the isolation tank 3 are all equipped with conveying ports 6, and the conveying ports 6 are precisely aligned with the conveying roller assembly 4 in the horizontal direction. The conveying port 6 of each tank provides a smooth entry path for the products to be electroplated, allowing them to smoothly enter the chemical tank for immersion treatment. The conveying port 6 not only ensures continuous material conveying but also enables the conveying roller assembly 4 to work in coordination between different tanks, ensuring smooth transfer of electroplated products and avoiding problems such as liquid leakage or unstable transfer of electroplated products due to unreasonable design of the seams between tanks.

[0036] In one example, a conveyor frame 7 is inserted through the conveyor port 6, and a plurality of mounting slots are provided on the upper end face of the conveyor frame 7, and the conveyor roller group 4 is disposed in the mounting slots.

[0037] In the above embodiment, a conveyor frame 7 is inserted into the conveyor port 6, preferably two parallel ones. The upper surface of the conveyor frame 7 has several mounting slots. The conveyor roller assembly 4 is installed in the mounting slots to provide guidance for adjusting the conveying gap in the conveyor roller assembly 4, and to ensure that the conveyor roller assembly 4 is more securely fixed in the conveyor port 6, while also facilitating installation and maintenance. By placing the conveyor roller assembly 4 in the mounting slots of the conveyor frame 7, precise alignment and stable operation of the roller assembly are ensured, avoiding unstable conveying of electroplated products due to loose rollers or improper installation. Furthermore, the mounting slots facilitate the adjustment and replacement of the conveyor roller assembly 4, improving the maintenance efficiency and service life of the equipment.

This allows the lifting frame 506 to move up and down with the drive of the liquid cutting drive 502, thereby adjusting the lifting position of the tension adjusting roller 501. The lifting seat 505 enables the entire liquid cutting assembly to rise and fall smoothly to maintain constant tension and adapt to electroplated products of different thicknesses. Driven by the liquid cutting drive 502, the lifting frame 506 can precisely adjust the tension according to the actual needs of the electroplated products, ensuring that the amount of electroplating liquid carried out during the entire conveying process remains within the ideal range, avoiding unnecessary waste or uneven liquid coating.
