Description

Technical Field

[0001] The invention belongs to the technical field of coating equipment, and in particular relates to an ultrasonic electroplating device for special-shaped magnetic steel. Background Art

[0002] When electroplating small special-shaped magnets, one of the difficulties of the electroplating process is how to ensure that each magnet surface is in full contact with the plating solution to achieve a uniform plating effect. Due to the complex shape and small size of special-shaped magnets, a large number of magnets are usually stacked in a cage-like structure for electroplating in the traditional electroplating process. However, this stacking method easily leads to close contact between magnets, affecting the fluidity of the plating solution, making it impossible for some magnet surfaces to be in full contact with the plating solution, especially for magnets with deeper stacking positions, which may lead to uneven plating or defects.

[0003] To address this problem, existing electroplating cages are usually designed to rotate or flip the magnets to mix and flip them during the electroplating process, thereby increasing the coverage of the electroplating solution and improving the electroplating effect. However, when there are too many magnets or the stacking density is too high, a single flipping action cannot effectively solve the problem of insufficient contact between the magnet surface and the electroplating solution.

[0004] Thus, although flipping can improve the surface electroplating effect to a certain extent, there are still problems of low efficiency and uneven plating. Summary of the invention

[0005] In view of this, an object of the present invention is to provide an ultrasonic electroplating device for special-shaped magnetic steel, which improves the electroplating efficiency by configuring the electroplating cage to be a plurality of expandable cage-like structures.

As the hanger drives the electroplating cage to move downward, the slide seat moves toward the middle of the rotating shaft along the arc rail.

[0008] Furthermore, rollers are coaxially fixed at both ends of the rotating shaft, two conveyor belts are provided inside the electroplating pool, the conveyor belts are driven by the same motor, the two conveyor belts are respectively located under the two rollers, and the hanger drives the electroplating cage to move downward so that the rollers contact the conveyor belts respectively.

[0009] Furthermore, a plurality of protrusions are respectively provided on the two conveyor belts, and the protrusions are arranged at intervals on the conveyor belts. One side of the protrusion is an arc surface, and the other side is a plane in contact with the surface of the conveyor belt. One end of the protrusion is hinged to the surface of the conveyor belt.

[0010] Furthermore, the raised portions on the two conveyor belts are staggered so that the electroplating cage moving along the conveyor belts can swing up and down respectively left and right under the support of the raised portions.

[0011] Furthermore, a winder is provided on the bracket, a sling rope is wound around the winder, and the sling rope is connected to the hanger.

DETAILED DESCRIPTION

[0024] like Figure 1 to Figure 6 As shown, the present invention discloses an ultrasonic electroplating device for special-shaped magnetic steel, such as Figure 1 and Figure 2 As shown, it includes an electroplating cage 1, which includes a rotating shaft 11, and a support 12 is provided near the two ends of the rotating shaft 11. Six sliding rods 13 are provided around the support 12. A triangular plate 14 is slidably provided on the sliding rod 13. The triangular plate 14 is an equilateral triangle with an angle of 60°. The sliding direction of the triangular plate 14 is perpendicular to the rotating shaft 11. Slide seats 15 are also slidably provided at both ends of the rotating shaft 11. The slide seat 15 is hinged with a support rod 16. The other end of the support rod 16 is hinged with the outer end of the triangular plate 14. The two ends of the rotating shaft 11 are located at the two ends of the rotating shaft 11. The triangular plates 14 are connected by a plurality of levers 17 to form a triangular cage structure for holding special-shaped magnetic steel. If necessary, a door structure is provided on the triangular cage structure for placing and recovering the special-shaped magnetic steel. The six triangular cage structures are combined to form a hexagonal cage structure, which also includes a bracket 2 and an electroplating pool 3. The bracket 2 is fixed above the electroplating pool 3. A hanger 4 is vertically slidably provided on the bracket 2. Both ends of the rotating shaft 11 are rotatably provided on the hanger 4. A winder 6 is provided on the bracket 2. The winder 6 is wound with a hanging rope 61. The hanging rope 61 is connected to the hanger 4. Figure 3 As shown, the bracket 2 is also provided with two arc rails 21, one end of the slide 15 is a hemispherical structure, and the hemispherical structure of the slide 15 contacts the arc rail 21. As the hanger 4 drives the electroplating cage 1 to move downward, the slide 15 moves along the arc rail 21 toward the middle of the rotating shaft 11. Figure 4As the slide 15 moves, the six triangular cages are in an open state. A spring may be provided between the slide 15 and the support 12 so that the spring surrounds the rotating shaft 11 to provide the slide 15 with a tendency to retract.

[0025] In this solution, the electroplating cage 1 is divided into several retractable triangular cage structures. The electroplating cage 1 can be transformed from an expanded state to a retracted state, which is convenient for the overall recovery and placement of parts. The electroplating cage 1 structure is divided into several triangular cage structures. Each side of the triangular cage structure is a rod body screen structure through which the plating liquid can flow. As the hanger 4 descends, the triangular cage structure opens in the electroplating pool 3, and the plating liquid can flow from each side of the triangular cage, providing a more dispersed electroplating space for the special-shaped magnetic steel in the electroplating cage 1, thereby improving the electroplating efficiency.

[0026] In a further solution, Figure 2 , Figure 3 and Figure 4 As shown, rollers 18 are coaxially fixed at both ends of the rotating shaft 11, and two conveyor belts 5 are provided inside the electroplating pool 3. The conveyor belts 5 are driven by the same motor. The two conveyor belts 5 are respectively located under the two rollers 18, and the hanger 4 drives the electroplating cage 1 to move downward so that the rollers 18 are in contact with the conveyor belts 5 respectively.

[0027] This structure, by setting a conveyor belt 5 structure, makes the plating cage 1 structure submerged in the plating pool 3 driven to rotate by two conveyor belts 5, so as to drive the plating cage 1 to rotate. As the plating cage 1 rotates, the special-shaped magnetic steel in each triangular cage moves randomly with the rotation of the triangular cage, so as to prevent the special-shaped magnetic steel in the pile from being piled up and the special-shaped magnetic steel cannot be evenly plated. Under the rotation of the triangular cage, the plating liquid and the triangular cage produce relative movement, so as to achieve a faster flow of the plating liquid between the special-shaped magnetic steel and the plating liquid, which can accelerate the flow of the plating liquid on the surface of the special-shaped magnetic steel, reduce the stagnant area of ​​the plating liquid on the surface, so that the plating liquid can cover each surface of the special-shaped magnetic steel more evenly, and avoid the phenomenon of uneven thickness of the plating layer.

[0028] For further solutions, refer to Figure 4 , Figure 5 and Figure 6 A plurality of raised portions 51 are respectively provided on the two conveyor belts 5 , and the raised portions 51 are arranged at intervals on the conveyor belt 5 . One side of the raised portion 51 is an arc surface, and the other side is a plane in contact with the surface of the conveyor belt 5 . One end of the raised portion 51 is hinged to the surface of the conveyor belt 5 .

[0029] In this mechanism, by providing the raised portion 51, the roller 18 is caused to bump up and down on the conveyor belt 5, causing the pile of shaped magnetic steels in the electroplating cage 1 to shake, so that the relative positions of the shaped magnetic steels are constantly changed, so that the electroplating liquid can cover every corner of the magnetic steel, especially the grooves or corner areas that are difficult to electroplate, thereby improving the overall uniformity of the coating.

[0030] In a further solution, Figure 5 As shown, the raised portions 51 on the two conveyor belts 5 are staggered, so that the electroplating cage 1 moving along the conveyor belt 5 can swing left and right and up and down respectively under the support of the raised portions 51 .

[0031] First, by setting the staggered protrusions 51, the triangular cage can produce alternating left and right shaking in the electroplating solution, so that the special-shaped magnetic steel in the triangular cage no longer remains static, and the special-shaped magnetic steel is prevented from piling up. In particular, for special-shaped magnetic steels with complex shapes, if they are piled up together, it will not only affect the circulation of the electroplating solution, but also may cause uneven plating or failure to electroplate in place. Through shaking, the special-shaped magnetic steel can maintain a certain dispersion state, so that the surface of each special-shaped magnetic steel is fully in contact with the electroplating solution, ensuring uniform coverage and quality consistency of the electroplating layer.

[0032] Secondly, the alternating left-right shaking of the triangular cage causes the plating solution to flow, breaking the static state. This flow helps prevent the plating solution from being retained in certain areas or the uneven distribution of metal ions. The flow of the plating solution not only speeds up the transfer of metal ions, but also avoids the problem of excessive or low local current density during the electroplating process, further improving the uniformity, smoothness and adhesion of the coating.

[0033] The alternating left and right shaking not only maintains the dynamic dispersion of the magnetic steel, but also keeps the electroplating solution flowing continuously on the surface of complex shapes. This dual dynamic optimization ensures the full coverage of the coating, avoids local over-thickness or over-thinness of the deposition, and improves the quality of the coating.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
