Description

Technical Field

[0001] This utility model belongs to the field of neodymium iron boron processing technology, specifically relating to a loading device for electroplating neodymium iron boron magnets. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets are produced using a sintered powder metallurgy process. Their matrix material is porous, and the neodymium and other rare earth elements within them are highly susceptible to oxidation and failure in air. To extend their lifespan, electroplating or other non-electroplated surface protection treatments are necessary to ensure the NdFeB magnets meet usage requirements. During electroplating, the workpiece must be hung on a specific fixture to ensure even current flow and achieve a uniform electroplating effect.

[0003] In the prior art, such as Chinese Patent No. CN112410860A, a neodymium iron boron electroplating device is disclosed. In paragraph 0028 of the specification, a hanging rack assembly is disclosed. When picking up and putting down neodymium iron boron magnets, it is not convenient to pick up and put down neodymium iron boron magnets in the same layer as a whole.

[0004] Therefore, it is necessary to propose a loading device for electroplating neodymium iron boron magnets to solve the above problems. Utility Model Content

Detailed Implementation

[0024] like Figures 1-4 As shown, this utility model provides a loading device for electroplating neodymium iron boron magnets, including: a hook 1 and a support frame 2 fixedly connected to the hook 1. Multiple sets of hanging baskets 3 are fixedly connected inside the support frame 2. The support frame 2 is fixedly connected into a rectangle by two horizontal bars 201 and two vertical bars 202. The hanging basket 3 includes a base frame 302 and a loading rack 303 slidably connected to the base frame 302. The loading rack 303 is provided with a support plate 304 for supporting neodymium iron boron magnets. The support plate 304 is arranged in a mesh.

[0025] In this solution, during loading, multiple NdFeB magnets are placed on a mesh support plate 304, and then the loading rack 303 is slid into the hanging basket 3, which facilitates the simultaneous removal of multiple NdFeB magnets and improves the convenience of picking up and placing the NdFeB magnets as a whole; and the support plate 304 is set in a mesh shape to facilitate the electroplating solution to act on the bottom of the NdFeB magnets.

[0026] In one embodiment of this utility model, the vertical rod 202 is provided with multiple sets of connecting holes arranged side by side along the longitudinal direction. Each set of connecting holes includes at least two vertically arranged connecting holes 203. A connecting plate 301 is fixedly provided on the hanging basket 3. The connecting plate 301 is provided with bolts that correspond one-to-one with the connecting holes 203 in the same set of connecting holes. The connecting plate 301 is connected to the connecting holes 203 by bolts to fix it on the vertical rod 202.

[0027] In this solution, the installation of the hanging basket 3 is facilitated by setting up a group of connecting holes, and the installation height and number of the hanging basket 3 can be adjusted according to the electroplating requirements.

[0028] In one embodiment of this utility model, multiple sets of guide rods are arranged side by side on the base frame 302 along the extension direction of the crossbar 201. Each guide rod set includes two guide rods 305 provided with vertical support frames 2. An L-shaped connecting plate 306 that cooperates with the guide rod 305 is fixedly welded to the bottom of the loading rack 303. The horizontal section of the L-shaped connecting plate 306 abuts against the top of the guide rod 305 so that the guide rod 305 supports the loading rack 303. The vertical section of the L-shaped connecting plate 306 abuts against the guide rod 305 to limit the lateral displacement of the loading rack 303 mounted on the guide rod 305.

[0029] In one embodiment of this utility model, two hooks 1 are provided, and the two hooks 1 are fixedly connected to the two ends of one of the two crossbars 201 to ensure the stability of the support frame 2 suspended by the hooks 1.

[0030] In one embodiment of the present invention, a first guardrail 307 is fixedly welded to the first side of the base frame 302 along the axial direction of the guide rod 305. The first guardrail 307 includes a plurality of first support rods 308 welded side by side to the base frame 302, and a plurality of first limiting rods 309 fixedly connected to the top of the first support rods 308. The side wall of the loading rack 303 abuts against the first support rods 308, so that the first limiting rods 309 abut against the top wall of the loading rack 303, thereby limiting the longitudinal displacement of the loading rack 303.

[0031] In one embodiment of the present invention, a second guardrail 310 is rotatably connected to the second side of the base frame 302 along the axial direction of the guide rod 305. The second guardrail 310 includes a plurality of second support rods 311 rotatably connected to the base frame 302, and a plurality of second limiting rods 312 fixedly connected to the top of the second support rods 311. Rotating the second support rods 311 can cause the second limiting rods 312 to abut against the top wall of the loading rack 303.

[0032] In this scheme, before the loading rack 303 is slid into the base frame 302, the second guardrail 310 is in the open state. After the loading rack 303 is slid into the base frame 302, the second guardrail 310 is rotated so that the second limiting rod 312 abuts against the top wall of the loading rack 303. The first limiting rod 309 and the second limiting rod 312 are used to improve the stability of the longitudinal displacement of the loading rack 303.

[0033] In one embodiment of the present invention, the first support rod 308 is L-shaped, the vertical section of the first support rod 308 is welded and fixed to the base frame 302, the horizontal section of the first support rod 308 extends towards the second guardrail 310, and the first limiting rod 309 is welded and fixed to the end of the horizontal section of the first support rod 308; the second support rod 311 is straight, and the second limiting rod 312 is welded and fixed to the second support rod 311 near the side of the first guardrail 307.

[0034] In this solution, by setting the first support rod 308 in an L-shape, the distance by which the first limiting rod 309 extends to the top of the loading rack 303 is ensured, thereby limiting the longitudinal displacement of the loading rack 303. By setting the second support rod 311 in a straight line, the second limiting rod 312 is set close to the second support rod 311, so that the second limiting rod 312 can cover the loading rack 303 after the second guardrail 310 is flipped.

[0035] In one embodiment of the present invention, the second limiting rod 312 is slidably connected to an insert rod 313 that can slide along the axis of the second support rod 311, and the base frame 302 is provided with a through hole 314 that is perpendicular to the base frame 302 and cooperates with the insert rod 313.

[0036] In this design, when the second guardrail 310 is rotated to keep the second support rod 311 vertical, the insertion rod 313 is inserted into the through hole 314 to restrict the rotation of the second guardrail 310.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
