[0002] When electroplating is performed using a hanger, the material to be electroplated is mounted on the hanger, and the material and the hanger as a whole serve as a cathode. Since the electric field in the electroplating solution includes not only straight-line electric force lines parallel to each other, but also arc-shaped electric force lines converging toward the edges of the electrode, edge effects exist in hanger plating. For example, due to the edge effects, the deposition rate of the plating layer at the corners of a single sintered neodymium-iron-boron magnet is greater than that at the edge of the sintered neodymium-iron-boron magnet, so that the final plating layer thickness of the neodymium-iron-boron magnet is uneven.

[0038] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] As shown in Figure 1 , an embodiment of the present application provides a hanger 10, which comprises a frame 11, a hook 12 and a hanger stop 13. The hook 12 is arranged on the frame 11, and the hook 12 is used for hanging a material to be electroplated. When the material is electroplated, the material is hung on the hook 12, and the hanger 10 is placed in an electroplating solution.

[0040] The hanger stop 13 is arranged on the frame 11, and the hanger stop 13 is an insulator. For example, the surface of the hanger stop 13 is coated with an insulating paint, and the insulating paint is at least one of polyvinyl chloride, perchloroethylene paint and neoprene. When electroplating, the hanger stop 13 can adjust the distribution of electric lines near the hanger 10 in the electroplating solution.

[0041] As shown in Figure 2 , the dashed line in Figure 2 represents an electric line. Since the hanger stop 13 is an insulator, the charged ions near the hanger stop 13 cannot pass through the hanger stop 13 and need to bypass the hanger stop 13 to reach the surface of the material, thereby changing the distribution of the electric lines at the edge of the material. The hanger stop 13 can reduce the discharge rate of metal ions on the material near the hanger stop 13, and the cathode polarization effect, so that the current in the high and low current areas of the electroplating solution is more evenly distributed, effectively alleviating the edge effect of electroplating, and improving the thickness uniformity of the plating layer on the material.

[0042] As shown in Figure 3As shown, in some embodiments, the frame 11 comprises: a first vertical rod 111, a first horizontal rod 112, and a support rod 113. The number of the first vertical rod 111 and the first horizontal rod 112 is two, the first horizontal rod 112 is connected to the first vertical rod 111, and the two first vertical rods 111 and the first horizontal rod 112 form a rectangle. A plurality of support rods 113 are arranged in parallel with the first horizontal rod 112, one end of the support rod 113 is connected to one side of the first vertical rod 111, and the other end of the support rod 113 is connected to the other side of the first vertical rod 111. The hanger 12 is arranged on the support rod 113. Optionally, a plurality of hangers 12 are arranged on each support rod 113.

[0043] The hanger stop 13 comprises: a second vertical rod 131, a second horizontal rod 132, and a support rod 133. The number of the second vertical rod 131 and the second horizontal rod 132 is two, the second vertical rod 131 is parallel to the first vertical rod 111, and the second horizontal rod 132 is parallel to the first horizontal rod 112. The second horizontal rod 132 is connected to the second vertical rod 131, and the two second vertical rods 131 and the two second horizontal rods 132 form a rectangle. Optionally, the second vertical rod 131 is located directly above the corresponding first horizontal rod 112. One end of the support rod 133 is connected to the frame 11, and the other end of the support rod 133 is connected to the second vertical rod 131 and / or the second horizontal rod 132. Optionally, the length of the second vertical rod 131 is slightly smaller than the length of the first vertical rod 111. The second vertical rod 131, the second horizontal rod 132, and the support rod 133 are all insulators.

[0044] In some embodiments, the projection of the hanger stop 13 towards the hanger 12 at least partially blocks the material hung on the hanger 12. For example, the material is hung on the hanger 12, and the projection of the second vertical rod 131 towards the hanger 12 at least partially blocks the material hung on the hanger 12. For example, the projection of the second vertical rod 131 towards the hanger 12 can block the edge of the material to adjust the electric field distribution near the edge of the material and slow down the edge effect during electroplating of the material.

[0045] In some embodiments, the second vertical rod 131, the second horizontal rod 132, and the support rod 133 are all cylindrical. The diameter of the second vertical rod 131 is ≥0.5mm. If the diameter of the second vertical rod 131 is too small, the effect of simplifying the edge effect is poor. If the diameter of the second vertical rod 131 is too large, it may affect the uniformity of the electric field distribution near the hanger 10. The diameter of the second vertical rod 131 is set according to the requirements.

[0046] Optionally, the distance between the hanger stop 13 and the material hung on the closest hanger 12 is greater than 0.5cm.

[0047] As Figure 1As shown, in some embodiments, the hanger 10 further comprises a first hanging hook 14, the first hanging hook 14 comprising: an inclined portion 141 and a hook body 142. The inclined portion 141 is connected to the frame 11 at one end, for example, the inclined portion 141 is connected to the first crossbar 112. The inclined portion 141 is arranged to be inclined upward, and the other end of the inclined portion 141 is connected to the hook body 142. The hook body 142 is used to connect the hanging rack, so as to place the hanger 10 into the electroplating solution. The hanger 10 is generally in a vertical state in the electroplating solution.

[0048] Optionally, the hanger stopper 13 comprises a plurality of small stoppers, and the small stoppers are arranged on both sides of each hook 12. The shape and size of the small stoppers are set according to requirements.

[0049] As shown, in some embodiments, the hanger 10 further comprises a first hanging hook 14, the first hanging hook 14 comprising: an inclined portion 141 and a hook body 142. The inclined portion 141 is connected to the frame 11 at one end, for example, the inclined portion 141 is connected to the first crossbar 112. The inclined portion 141 is arranged to be inclined upward, and the other end of the inclined portion 141 is connected to the hook body 142. The hook body 142 is used to connect the hanging rack, so as to place the hanger 10 into the electroplating solution. The hanger 10 is generally in a vertical state in the electroplating solution. Figure 4

[0050] The hanger 10 is arranged on the hanging rack 20, for example, the hanger 10 is hung on the hanging rack 20 through the first hanging hook 14. The hanging stopper 30 is hung on the hanging rack 20, and the hanging stopper 30 is used to adjust the distribution of the overall cathode edge power line in the electroplating solution during electroplating.

[0051] After the hanger 10 is placed into the electroplating solution, the hanger 10 and the material hung thereon as a whole serve as a cathode. Compared with the middle part of the overall cathode, there is a more concentrated power line at the edge of the overall cathode. The hanging stopper 30 is arranged on the outside of the overall cathode, and the part of the hanging stopper 30 corresponding to the frame 11 of the hanger 10 is an insulator. The charged ions near the hanging stopper 30 cannot pass through the hanging stopper 30 and need to bypass the hanging stopper 30 to reach the surface of the material, thereby changing the distribution of the cathode edge power line in the electroplating solution, so that the current in the high and low current areas of the electroplating solution is more evenly distributed, effectively alleviating the edge effect of electroplating, and improving the thickness uniformity of the material plating layer.

[0052] As shown, in some embodiments, the hanging stopper 30 comprises: a third vertical rod 31, a third crossbar 32 and a second hanging hook 33. The third vertical rod 31 and the third crossbar 32 are both insulators. The number of the third vertical rod 31 and the third crossbar 32 is both two, and the two third vertical rods 31 and the two third crossbars 32 form a rectangle. The second hanging hook 33 is arranged on the top third crossbar 32, and the second hanging hook 33 is used to connect the hanging rack 20. Figure 5 In some embodiments, the projection of the third vertical rod 31 towards the hook 12 can completely cover the material hung by the hook 12. For example, the width D1 of each third vertical rod 31 should be greater than or equal to the width of the material, so that the projection of the third vertical rod 31 towards the hook 12 can completely cover the hung material.

[0053]

[0054] ​​Optionally, the length of the third vertical rod 31 is greater than or equal to the length of the first vertical rod 111.

[0055] In some embodiments, the number of the hanging stops 30 is at least two. For example, the plurality of hangers 10 forms a hanger combination, and two hanging stops 30 are respectively located on both sides of the hanger combination. According to the need, the hanging stops 30 can be arranged between the adjacent hangers 10.

[0056] In some embodiments, the distance between the hanging stops 30 and the hangers 10 is greater than or equal to 2 cm, so as to avoid the hanging stops 30 excessively affecting the deposition rate of the edge coating of the material.

[0057] Optionally, the distance between the hanging stops 30 and the hangers 10 is 2-4 cm.

[0058] The above describes the embodiments of the present application in detail. The principles and implementation manners of the present application are described by applying specific examples, and the above description of the embodiments is only used to help understand the technical solutions and core ideas of the present application.
