DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1—5. A wire contact electroplating device, comprising a double-layer frame 1, a process pool 2, and a downward pressure conveying roller 3. The upper layer of the double-layer frame 1 is fixedly connected with three groups of process pools 2. The three groups of process pools 2 are filled with pickling solution, alkaline washing solution, and activation solution from right to left. The pickling solution and alkaline washing solution are mainly used to remove grease, dirt and oxides on the surface of the wire, and the activation solution can activate the surface of the wire to increase its adhesion to the coating. The activation solution is hydrochloric acid or sulfuric acid solution;
[0033] In addition, two groups of process pools 2 are fixedly connected to the lower layer of the double-layer frame 1, and the two groups of process pools 2 are filled with electroplating solution and cleaning solution from left to right. Furthermore, the process pool 2 with electroplating solution is provided with an anode component. At the same time, one end of the process pool 2 with electroplating solution is rotatably connected with a cathode conductive roller 4, so that when the wire passes through the cathode conductive roller 4, the wire can be used as a cathode, and the anode component is a pure metal plate to be plated. After the anode component and the cathode conductive roller 4 are connected to a power source, the power source is turned on, and the current is introduced into the solution through the anode component, so that the anode material is gradually dissolved and metal ions are generated. These metal ions move to the cathode (wire) surface under the action of the electric field and obtain electrons there, thereby reducing to a metal state to form a uniform coating;
[0034] Furthermore, one side of the double-layer frame 1 is fixedly connected to multiple groups of guide columns 5, and a downward pressing frame 6 is slidably connected to the guide column 5. On the downward pressing frame 6, each group of process pools 2 is rotatably connected to a downward pressing conveying roller 3. The double-layer frame 1 is fixedly connected to a traction component 7, and the traction component 7 matches the downward pressing frame 6. The traction component 7 here can be an electric telescopic cylinder. In addition, each group of process pools 2 is rotatably connected to a plurality of first conveying rollers 8, and the middle frame of the double-layer frame 1 is fixedly connected to a plurality of first conveying rollers 8 at both ends thereof. The second conveying roller 9 guides the wires through the first conveying roller 8 and the second conveying roller 9, and arranges the wires at the lower part of the pressing conveying roller 3 when arranging the wires, so that it is convenient to arrange the wires through the pressing conveying roller 3, and the pressing conveying roller 3 can be driven down by the traction component 7, and the wires can be pressed down into the solution of the corresponding process pool 2 to achieve the processing of the wires, so that when arranging the wires, it is not necessary to pass the wires through the solution in the process pool 2, so as to facilitate the arrangement of the wires;
[0035] Further optimization is said that a circulation pump 10 is fixedly connected to one side of each group of process pools 2 on the double-layer rack 1, and the circulation pump 10 is connected to the corresponding process pool 2 through a first pipe. A second pipe 11 is fixedly connected to the circulation pump 10, and the second pipe 11 is located on the upper part of the process pool 2, so that the solution in the process pool 2 can be pumped out by the circulation pump 10, and then the pumped solution is transported to the process pool 2. Such a structure can make the solution in each group of process pools 2 flow, and the flowing electroplating solution can promote the uniform distribution of ions, which helps to ensure the uniformity and adhesion of the coating, because if the electroplating solution is stationary, it may form a thicker or thinner coating in certain areas of the workpiece, thereby affecting the overall quality and appearance of the coating, and the flowing other solutions can reduce solution bubbles and avoid precipitation of the solution;
[0036] Furthermore, the lower layer of the double-layer rack 1 is also fixedly connected to a drying device 12 corresponding to the process pool 2. The drying device 12 is located on one side of the process pool 2 with the cleaning solution. The drying device 12 includes a drying box and a heating component located in the drying box. The drying box is provided with an inlet 13 and an outlet 14. In this way, after the wire passes through the cleaning solution, it enters the drying box through the inlet 13, and the wire is dried by the high temperature generated by the heating component. The dried wire is then output through the outlet 14;

In this embodiment, it is realized by a wire unwinding and reeling integrated machine 15. Specifically, it includes a wire unwinding mechanism 16 and a wire reeling mechanism 17.

In this way, the untreated wire is rolled out to various process pools 2 through the wire unwinding mechanism 16, and the treated wire (pickling, alkali washing, activation, electroplating, cleaning, drying) is rolled up through the wire winding mechanism 17. The reversing assembly 20 is mainly used to realize reversal, so that the working directions of the wire unwinding mechanism 16 and the wire winding mechanism 17 are opposite;
[0038] Among them, the wire unwinding mechanism 16 includes a wire unwinding placement roller 21, a first transmission member 22, and a unwinding guide wheel 23. The upper part of the chassis 19 is rotatably connected to multiple groups of wire unwinding placement rollers 21, and each group of wire unwinding placement rollers 21 is provided with a first placement portion 24 for placing a wire wheel (wound with unprocessed wire), and multiple groups of first placement portions 24 are staggered, that is, after the wire wheels are installed, the wire wheels are not on the same surface. The first placement portion 24 here can be splined, and of course the wire wheels are also matched with spline openings, and one end of the multiple groups of wire unwinding placement rollers 21 penetrates into the chassis 19, and the multiple groups of wire unwinding placement rollers 21 located in the chassis 19 are connected to the power through the first transmission member 22 in turn. The chassis 19 is also rotatably connected to a unwinding guide wheel 23 on one side of each group of wire unwinding placement rollers 21, and the reversing assembly 20 is connected to one group of wire unwinding placement rollers 21.
[0039] Furthermore, the reversing assembly 20 includes a first gear 25, a second gear 26, and a reversing shaft 27. The reversing shaft 27 is rotatably connected in the chassis 19, and the first gear 25 is fixedly connected to the reversing shaft 27.

[0040] Furthermore, the wire winding mechanism 17 includes a wire winding placement roller 28, a second transmission member 29, a third transmission member 30 and a winding guide wheel 31. The lower part of the chassis 19 is rotatably connected to multiple sets of wire winding placement rollers 28. The wire winding placement rollers 28 are provided with a second placement portion 33 for placing a wire wheel (for winding the processed wire). The first placement portion 24 here can also be splined. Of course, the wire wheel is also matched with a spline mouth, and multiple sets of second placement portions 33 are staggered, that is, the wire wheel is installed After that, the wire wheels here are not on the same plane, one end of the multiple sets of wire winding and placing rollers 28 penetrates into the chassis 19, and the multiple sets of wire winding and placing rollers 28 located in the chassis 19 are connected by power through the second transmission member 29 in sequence, and the chassis 19 is located on one side of each set of wire winding and placing rollers 28.

The driving device 18 is used to drive the reversing shaft 27 to rotate, at which time the first gear 25 is rotated, and then the first gear 25 drives the second gear 26 to rotate, so that the corresponding wire winding and placement roller rotates. Under the action of the first transmission member 22, multiple groups of wire winding and placement rollers 28 rotate synchronously. At the same time, the rotating reversing shaft 27 can also drive the corresponding wire winding and placement rollers 28 to rotate through the third transmission member 30. Under the action of the second transmission member 29, multiple groups of wire winding and placement rollers 28 rotate synchronously, so that the winding and winding of the wire can be realized, the number of driving devices 18 is reduced, and more energy is saved.
