Description

Technical Field

[0001] This invention belongs to the technical field of neodymium iron boron (NdFeB) production equipment, specifically relating to a transferable automated warehouse for NdFeB magnet production. Background Technology

[0002] Currently, in the neodymium iron boron (NdFeB) permanent magnet industry, when block-shaped products from the previous process are transferred to this process, multiple products are placed close together on pallets, and then wrapped with tape to prevent them from falling. During the transfer of NdFeB magnets, forklifts are commonly used to support the boxes containing the magnets. This transfer process is prone to vibration, causing the NdFeB magnets to bump and knock. During repeated transfers, the brittle NdFeB material is prone to chipping at the edges and corners.

[0003] In existing technologies, the common approach is to install elastic damping mechanisms on forklifts to reduce vibration during transport. However, since elastic damping cannot completely eliminate vibration, and placing neodymium iron boron magnets on the transport box requires methods such as securing them with tape, the transport efficiency is low.

[0004] Therefore, it is necessary to propose a transferable automated warehouse for the production of neodymium iron boron magnets to solve the above problems. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a transferable automated warehouse for the production of NdFeB magnets, which solves the problems of easy collision and low transfer efficiency of NdFeB magnets during the transfer process in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention discloses a transferable automated warehouse for the production of neodymium iron boron magnets, comprising a base and a box fixedly mounted on the base. Multiple clamping plates are slidably mounted vertically within the box, forming a placement layer for neodymium iron boron magnets between adjacent clamping plates. Each clamping plate includes two symmetrically arranged U-shaped plates within the box, with their openings facing away from each other. Scissor-type telescopic frames are mounted on opposite side walls within the box, with their two ends hinged and slidably connected within the U-shaped plates. A support plate is fixedly mounted between the two U-shaped plates, with a notch in the center of the support plate containing an elastic airbag. The scissor-type telescopic frames allow the multiple clamping plates to move at equal intervals. When two adjacent clamping plates are close together, the elastic airbags on the two clamping plates can clamp the neodymium iron boron magnets.

[0007] Furthermore, the housing is rotatably connected to a plurality of bidirectional screws corresponding to one of the clamping plates. The two end hinge points of the scissor-type telescopic frame corresponding to the clamping plate are threadedly connected to the opposite threads of the bidirectional screws. Rotating the bidirectional screws can make the two end hinge points on the scissor-type telescopic frame move closer or further apart, thereby increasing or decreasing the distance between adjacent clamping plates.

[0008] Furthermore, there are two bidirectional screws, and two U-shaped plates are arranged between the two bidirectional screws. One end of each bidirectional screw is fixedly connected to a worm gear, and a worm gear that meshes with both worm gears is rotatably connected to the housing. Rotating the worm gear can make the two worm gears rotate synchronously.

[0009] Furthermore, the two U-shaped plates have sliding holes on their adjacent sidewalls, and sliders are slidably connected within the sliding holes. The two end hinge points of the scissor-type telescopic frame are respectively hinged to the two sliders. The support plate includes support rods corresponding to the two sliders. The support rods are inserted and fixed to the sliders, and a gap is formed between the two support rods. The two sliders can move closer or further away from each other, so that the two support rods can move closer or further away from each other, thereby reducing or increasing the gap, thereby causing the elastic airbag to contract or stretch.

[0010] Furthermore, a push plate is fixedly installed between the two U-shaped plates, and the support rod is provided with a groove corresponding to the push plate. The support rod is slidably sleeved on the push plate through the groove, so that a sealed cavity is formed between the push plate and the inner wall of the groove. The support rod is provided with an air hole that connects the elastic airbag and the sealed cavity.

[0011] Furthermore, the central hinge point of the scissor-type telescopic frame is located at the center of the placement layer. The central hinge point of one of the two scissor-type telescopic frames is sleeved on the air inlet pipe, and the central hinge point of the other scissor-type telescopic frame is sleeved on the air intake pipe. The air inlet pipe is connected to a jet mechanism, and the air intake pipe is connected to a negative pressure mechanism.

[0012] Furthermore, the base is provided with a slot for cooperating with a forklift.

[0013] The beneficial effects of this invention are as follows: This invention uses an elastic airbag to hold the neodymium iron boron magnet. Due to the elastic deformation capability of the elastic airbag itself and the gas inside the elastic airbag enveloping the neodymium iron boron magnet, the neodymium iron boron magnet can be prevented from being bumped or knocked during the movement of the box. Attached Figure Description

[0014] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the following figures are provided for illustration: Figure 1 This is a schematic diagram of the internal structure of the box according to an embodiment of the present invention; Figure 2 This is a front view of the overall structure of an embodiment of the present invention; Figure 3 This is a cross-sectional view of two adjacent clamping plates in an embodiment of the present invention; Figure 4 This is a cross-sectional view of the clamping plate structure according to an embodiment of the present invention.

[0015] The following are the markings in the attached diagram: base 1, slot 101, box 2, clamping plate 3, U-shaped plate 301, support plate 302, notch 303, elastic airbag 304, sliding hole 305, slider 306, support rod 307, push plate 308, sealing cavity 309, air hole 310, scissor-type telescopic frame 4, end hinge point 401, middle hinge point 402, air inlet pipe 403, air intake pipe 404, double-acting screw 5, worm gear 501, worm 502. Detailed Implementation

[0016] like Figures 1-4 As shown, this invention discloses a transferable automated warehouse for neodymium iron boron magnet production, comprising: a base 1 and a box 2 fixedly installed on the base 1. Multiple clamping plates 3 are slidably installed vertically inside the box 2. Each clamping plate 3 includes two symmetrically arranged U-shaped plates 301 within the box 2, with their openings facing away from each other. Scissor-type telescopic frames 4 are installed on opposite side walls inside the box 2. The two end hinge points 401 of the scissor-type telescopic frames 4 are slidably connected to the U-shaped plates 301. A support plate 302 is fixedly installed between the two U-shaped plates 301. A notch 303 is provided in the middle of the support plate 302, and an elastic airbag 304 is fixedly installed within the notch. The scissor-type telescopic frames 4 allow the multiple clamping plates 3 to move at equal intervals. When two adjacent clamping plates 3 are close together, the neodymium iron boron magnets can be clamped by the elastic airbags 304 on the two clamping plates 3.

[0017] In this scheme, when placing the neodymium iron boron magnet, the distance between two adjacent clamping plates 3 is first increased by the scissor-type telescopic frame 4. After the neodymium iron boron magnet is placed on the elastic airbag 304, the distance between two adjacent clamping plates 3 is reduced by the scissor-type telescopic frame 4 so that the upper and lower elastic airbags 304 clamp the neodymium iron boron magnet.

[0018] This solution uses an elastic airbag 304 to hold the neodymium iron boron magnet. Due to the elastic deformation capability of the elastic airbag 304 itself and the gas inside the elastic airbag 304 enveloping the neodymium iron boron magnet, it can prevent the box 2 from bumping or hitting the neodymium iron boron magnet during movement.

[0019] In one embodiment of the present invention, a bidirectional screw 5 corresponding to one of the multiple clamping plates 3 is rotatably connected inside the housing 2. The two end hinge points 401 of the scissor-type telescopic frame 4 corresponding to the clamping plate 3 are threadedly connected to the opposite threads of the bidirectional screw 5. Rotating the bidirectional screw 5 can make the two end hinge points 401 on the scissor-type telescopic frame 4 move closer or further away from each other, so as to increase or decrease the distance between the multiple clamping plates 3.

[0020] In this scheme, the movement of the scissor-type telescopic frame 4 is controlled by rotating the bidirectional screw 5, so as to achieve the purpose of controlling the movement of the clamping plate 3 at equal intervals.

[0021] In one embodiment of the present invention, two bidirectional screws 5 are provided, and two U-shaped plates 301 are disposed between the two bidirectional screws 5. One end of the bidirectional screw 5 is fixedly connected to a worm gear 501, and a worm 502 that meshes with the worm gear 501 is rotatably connected to the housing 2. Rotating the worm 502 can make the two worm gears 501 rotate synchronously.

[0022] In this scheme, bidirectional screws 5 are provided on both sides of one of the multiple clamping plates 3 to ensure the smooth movement of the clamping plate 3.

[0023] In one embodiment of the present invention, the sidewalls of the two U-shaped plates 301 that are close to each other are provided with sliding holes 305. A slider 306 is slidably connected in the sliding holes 305. The two end hinge points 401 of the scissor-type telescopic frame 4 are respectively hinged to the two sliders 306. The support plate 302 includes support rods 307 corresponding to the two sliders 306 respectively. The support rods 307 are inserted and fixed to the sliders 306. A notch 303 is formed between the two support rods 307. The two sliders 306 moving closer or further away from each other can cause the two support rods 307 to move closer or further away, thereby reducing or increasing the notch 303, thereby causing the elastic airbag 304 to contract or stretch.

[0024] In this design, when a neodymium iron boron magnet is placed between two clamping plates 3, the two end hinge points 401 of the scissor-type telescopic frame 4 are moved away from each other by rotating the bidirectional screw 5. This causes the two clamping plates 3 to move closer together to vertically clamp the neodymium iron boron magnet, and the elastic airbag 304 is elastically stretched. As the space inside the elastic airbag 304 increases, the stretched elastic airbag 304 is in a pre-tensioned state, like a layer of taut elastic skin. When it comes into contact with irregular objects, it can more actively "flow" and conform to the microscopic surface texture of the object, producing a "mechanical locking" effect similar to a suction cup or adhesion. This not only resists slippage but also significantly increases the maximum static friction force. At the same time, it increases the tension of the elastic airbag 304, so that in the vertical clamping direction, the elastic airbag 304 remains flexible (conforming to the shape of the object without generating impact); but in the horizontal direction, it becomes "rigid" due to stretching, effectively resisting the sliding or rotation of the object in the horizontal direction. This achieves the decoupled clamping characteristics of vertical compliance and horizontal stability, improving the clamping stability of neodymium iron boron magnets.

[0025] In one embodiment of the present invention, a push plate 308 is fixedly installed between two U-shaped plates 301. The support rod 307 is provided with a groove corresponding to the push plate 308. The support rod 307 is slidably sleeved on the push plate 308 through the groove, so that a sealed cavity 309 is formed between the push plate 308 and the inner wall of the groove. The support rod 307 is provided with an air hole 310 that connects the elastic airbag 304 and the sealed cavity 309.

[0026] In this design, when the two support rods 307 move away from each other, the movement of the support rods 307 compresses the sealing cavity 309, causing the air inside the sealing cavity 309 to flow into the elastic airbag 304 through the air hole 310. This causes the elastic airbag 304 to expand further, forming a protrusion that matches the edge of the NdFeB magnet, thus limiting the horizontal displacement of the NdFeB magnet. In particular, when multiple NdFeB magnets are placed on the elastic airbag 304, the movement of the support rods 307 causes the elastic airbag 304 to stretch, and the deformation of the elastic airbag 304 causes the multiple NdFeB magnets to move away from each other. The compression of the sealing cavity 309 causes the elastic airbag 304 to expand, forming a protrusion that separates two adjacent NdFeB magnets. This increases the number of NdFeB magnets that can be transferred and prevents multiple NdFeB magnets in the same layer from colliding with each other.

[0027] In one embodiment of the present invention, a placement layer for placing neodymium iron boron magnets is formed between two clamping plates 3. The central hinge point 402 of the scissor-type telescopic frame 4 is located at the center of the placement layer. The central hinge point 402 of one of the two scissor-type telescopic frames 4 is sleeved on the air inlet pipe 403, and the central hinge point 402 of the other of the two scissor-type telescopic frames 4 is sleeved on the air intake pipe 404. The air inlet pipe 403 is connected to a jet mechanism (not shown in the figure), and the air intake pipe 404 is connected to a negative pressure mechanism (not shown in the figure).

[0028] In this solution, the jetting mechanism and the negative pressure mechanism are conventional technical means in this field and will not be described in detail here. This solution uses the jetting mechanism to spray gas to blow away the dust on the NdFeB magnets and uses the negative pressure mechanism to collect the dust. This allows the NdFeB magnets to be pre-treated during the transfer process, and ensures that the air intake and suction are always kept in the center of the placement layer for NdFeB magnets of different sizes.

[0029] In one embodiment of the present invention, the base 1 is provided with a slot 101 for cooperating with a forklift, and the forklift supports the base 1 through the slot 101.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended 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 to it in form and detail without departing from the scope defined by the claims of the present invention.
