Description

Technical Field

[0001] The present application relates to the technical field of metal surface treatment, and in particular to a composite coating treatment device for copper-nickel-gold-tin plated wires. Background Art

[0002] With the advancement of science and technology and the increasingly diversified needs of industrial production, the surface treatment technology of metal materials, especially electroplating technology, has developed rapidly. Traditional single metal coatings can no longer meet the high requirements of modern industry for material performance. Multi-metal composite coatings have attracted extensive attention due to their excellent physical and chemical properties. These composite coatings not only improve the corrosion resistance, wear resistance and conductivity of materials, but also greatly broaden their application scope and promote the technological progress and development of related industries.

[0003] At present, in order to achieve multi-layer composite electroplating of metal materials, the methods usually adopted include but are not limited to the standard process of pretreatment-electroplating-post-treatment. The pretreatment stage mainly includes steps such as cleaning and degreasing, pickling and rust removal, and activation. The purpose is to remove grease, oxides and other impurities on the surface of the material to ensure a good combination of the substrate and the coating. In the electroplating stage, voltage is applied by a DC power supply to deposit different metal ions in the electrolyte solution to form the required multi-layer coating in turn; however, this traditional process has the problem of high operational complexity and long time consumption in multiple links. In addition, for large-scale production lines, due to the limited degree of equipment automation, production efficiency is often low and product quality is difficult to maintain consistency. Especially in the nickel plating process, the load capacity of the original production line drive device limits the maximum size and weight of the processable plate, which becomes one of the key factors restricting the improvement of production efficiency.

[0004] Although the existing multi-metal composite electroplating technology can meet market demand to a certain extent, it still has many shortcomings. The first is that the overall process is long, the conversion rate from raw materials to finished products is low, the energy consumption is high, and the environmental pollution is serious. Secondly, the equipment is aging and the technology is updated slowly. Many factories still rely on manual or semi-automatic operation modes, which not only increases labor costs, but also prolongs the production cycle and cannot adapt to the rapidly changing market rhythm; thirdly, there is a relative lack of improvement measures for specific process links. For example, in the nickel plating stage, the drive system on the traditional production line is underpowered and cannot carry heavier metal plates, which easily causes jumper failures.

[0005] Therefore, in view of the above-mentioned related technologies, a composite coating processing device for copper-nickel-gold-tin plated wire is proposed. Summary of the invention

[0011] By adopting the above technical scheme, the metal coil first passes through the No. 1 cleaning tank to remove oil and impurities on the surface of the metal coil, and then enters the metal activation tank to activate the metal coil, laying the foundation for the subsequent electroplating process. After the activation is completed, the metal coil first enters the copper plating tank for copper plating to form a uniform copper plating layer, and after the copper plating work is completed, it enters the nickel plating tank for nickel plating.

Once it is detected that the speed difference exceeds the set threshold, the signal output is immediately adjusted to prompt the lagging party to speed up the operation until synchronization is restored. The synchronous driver controls the three groups of driving motors through an external control device for synchronous driving, ensuring that the transmission actions of each motor move synchronously, and smoothly pulls the electroplated plate to prevent deformation or damage of the plate caused by the speed difference.

[0028] Compared with the prior art, the composite coating processing device for copper-nickel-gold-tin wire can further enhance the control of the plate by clamping and fixing the metal coil through the coil clamping device and the coil guide wheel.

The carrying capacity of the production line can be enhanced by adding an independent driving wheel in front of the nickel plating pool, from the original 23kg / roll to 65kg / roll, which greatly increases the single processing volume, reduces the frequency of material changes, and reduces production costs. The design of the independent driving wheel effectively alleviates the problem of uneven tension distribution during plate transmission, significantly reduces the probability of wire jump accidents, and greatly improves the product qualification rate. In addition, the drive system composed of high-performance motors and precision reducers is used to achieve precise control of the plate transmission speed, ensuring the quality stability and consistency of the entire electroplating process.

[0045] The implementation principle of Example 2 of the present application is as follows: the driving motor 6 drives the driving shaft 63 to rotate through the reducer 62, and the encoder 621 can be used to detect the rotation of the driving shaft 63, and the rotation of the driving shaft 63 can be controlled by the detection result. Once it is detected that the speed difference exceeds the set threshold, the signal output is immediately adjusted to prompt the lagging party to speed up the operation until synchronization is restored. The three groups of driving motors 6 are controlled by the synchronous driver 61 through an external control device for synchronous driving, ensuring that the transmission actions of each motor move synchronously, and the electroplated sheet is smoothly pulled to prevent the sheet from being deformed due to the speed difference. The lifting cylinder 74 drives the lifting slide 731 and the pressure wheel motor 73 connected thereto to move up and down along the lifting slot 711 in the lifting slide 731, and drives the fixed pressure wheel 72 to approach or move away from the coil guide wheel 3 through the pressure wheel motor 73, and forms an upper and lower clamping form with the fixed pressure wheel 72 and the coil guide wheel 3, and the pressure wheel motor 73 can drive the fixed pressure wheel 72 to rotate, and the pressure size can be flexibly adjusted according to actual needs, so as to further enhance the control over the plate.

[0046] The implementation principle of Example 3 of the present application is as follows: the detection data of the photoelectric correction detector 53 can be used to drive the guide connecting frame 51 to rotate and correct on the correction base 54 by the correction cylinder 55, and the correction cylinder 55 drives the telescopic gear plate 551 to perform telescopic movement, and the telescopic gear plate 551 drives the rotating transmission gear 56 to rotate forward and reverse during the telescopic movement, and the rotating transmission gear 56 drives the rotating connecting frame 541 to rotate on the rotating connecting disk 542 during the forward and reverse movement, thereby driving the two groups of guide correction rollers 52 on the guide connecting frame 51 and the metal coils fixed thereon to perform offset movement, and the telescopic movement of the telescopic gear plate 551 is limited by the limiting protrusion 552 to prevent the correction movement from being too large.
