Description

Technical Field

[0001] The utility model relates to the technical field of NdFeB permanent magnet production equipment, in particular to a transfer device for NdFeB sintered bodies. Background Art

[0002] In the field of permanent magnet materials, sintered NdFeB magnets (NdFeB) are widely used in high-end manufacturing industries such as motors, wind power generation, and new energy vehicles due to their excellent magnetic properties. Sintering is a crucial step in the production of sintered NdFeB magnets, directly impacting the final product performance. However, post-sintering material handling, particularly the transfer of sintered magnets, still faces numerous challenges, requiring urgent technological improvements to enhance production efficiency and safety.

[0003] At present, a multi-step, multi-equipment transfer method is generally adopted for NdFeB sintered bodies from being taken out of the sintering furnace to entering the next process. Specifically, this process usually includes three main steps: first, the NdFeB sintered bodies that have completed high-temperature sintering are transferred to transfer vehicle A by directly docking with the sintering furnace outlet to achieve initial unloading; then, transfer vehicle A needs to further dock with a special transfer device to transfer the sintered bodies from transfer vehicle A to the device for intermediate processing or temporary storage; finally, another transfer vehicle B docks with the transfer device to transfer the sintered bodies from the device to transfer vehicle B for transportation to the subsequent process area.

[0004] This multi-step, multi-device reprinting method has obvious drawbacks:

[0005] Low work efficiency: Multiple transfers increase operational complexity and time costs, especially in a production environment with a low degree of automation. Frequent manual intervention can easily lead to longer production cycles and affect overall production efficiency.

[0006] Great safety hazard: For heavy sintered bodies, during multiple transfers, due to limitations of equipment docking accuracy, mechanical stability and other factors, lifting and shaking are prone to occur, which not only increases equipment wear, but also greatly increases the risk of transfer collapse, posing a threat to the personal safety of operators.

[0007] High costs: Multi-step transshipment requires multiple sets of transfer equipment and auxiliary facilities, increasing equipment investment and maintenance costs. Furthermore, low efficiency indirectly increases unit production costs. Utility Model Content

The active rollers are driven to rotate synchronously by a driving assembly.

[0012] Furthermore, the driving assembly includes a conveying motor fixedly arranged on the base plate, and the conveying motor cooperates with the gear chain assembly to synchronously drive each of the active rollers to rotate.

[0013] Furthermore, rail plates are provided on the fixed seats on both sides through bracket support, the material plate is placed on the active roller and the passive roller between the two rail plates, and the active roller and the passive roller are provided on the fixed seats through bearing sleeves.

[0014] Furthermore, a plurality of guide wheels are rotatably provided at the bottom of the track plate, and two sides of the material plate are in contact with the guide wheels.

[0028] like Figure 1-3 As shown, a transfer device for NdFeB sintered bodies includes a frame 3, a material lifting mechanism 2 mounted on the frame 3, and a material conveying mechanism 1 mounted on the frame 3 and driven to move upward and downward by the material lifting mechanism 2. NdFeB sintered bodies are conveyed on the material conveying mechanism 1. The material conveying mechanism 1 includes a base plate 12, a plurality of fixed seats 11 evenly spaced along the conveying direction on the base plate 12, and a plurality of rows of active rollers 6 and passive rollers 18 rotatably mounted on the fixed seats 11 along the conveying direction. The active rollers 6 are mounted on both sides of the material conveying direction, and the passive rollers 18 are mounted between the active rollers 6 on both sides. The active rollers 6 are driven to rotate synchronously by a drive assembly. The drive assembly includes a conveying motor 4 fixed to the base plate 12. The conveying motor 14 cooperates with a gear chain assembly 5 to synchronously drive each of the active rollers 6 to rotate.

[0029] First, the sintered NdFeB sintered body is placed on the material plate 19 of the material conveying mechanism 2, which is then placed on the roller conveyor belt composed of the active roller 6 and the passive roller 18. The active roller 6 is arranged on both sides of the material conveying direction, and its rotation provides the forward force for the material, while the passive roller 18 is located between the two active rollers 6, which plays a role in supporting and guiding the material.

[0030] Next, the drive assembly begins operating. Its core is the conveyor motor 4, fixed to the base plate 12. Once activated, the motor transmits power to the drive rollers 6 on each side via the connected gear chain assembly 5. The design of the gear chain assembly 5 ensures that all drive rollers 6 rotate synchronously, ensuring smooth and continuous material conveyance.

[0031] As the active roller 6 rotates, the material plate and the sintered body thereon begin to move along the conveying direction. During this process, both sides of the material plate contact the guide structures provided on the fixed seat 11, which guide and stabilize the material plate to prevent it from deflecting or shaking during conveying.

[0032] When the material is transported to the designated location, the material lifting mechanism 2 starts working. The material lifting mechanism 2 drives the material conveying mechanism 2 as a whole to rise or fall through the worm gear elevator to adapt to different working heights or docking different transfer forklifts.

[0033] Specifically, as shown in the figure, rail plates 17 are supported on the fixed seats 11 on both sides by brackets 16. A material plate 19 is placed on the active roller 6 and passive roller 18 between the two rail plates 17. The active roller 6 and passive roller 18 are mounted on the fixed seats 11 via bearing sleeves 7. Several guide wheels 10 are rotatably mounted on the bottom of the rail plates 17, and the two sides of the material plate 19 contact the guide wheels 10. The rail plates 17 are located at the conveying end, equipped with a photoelectric sensor 8 for sensing the delivery of materials. The fixed seat 11 is also located at the conveying end, equipped with a safety latch 9 for positioning the materials.

[0034] When the conveying motor 4 is started, the power is transmitted to the active rollers 6 on both sides through the gear chain assembly 5, so that they rotate synchronously.

[0035] The rotation of the active roller 6 drives the material plate 19 in contact with it and the sintered body thereon to move along the conveying direction. The passive roller 18 then plays the effect of supporting and guiding the material plate 19, ensuring that it remains stable during the movement.

[0036] The guide wheels 10 rotatably mounted at the bottom of the track plate 17 contact both sides of the material plate 19, providing additional guidance and stability for the material plate 19. This helps reduce the deviation and shaking of the material plate 19 during transportation, ensuring that the sintered body can be accurately and smoothly transported to the designated location.

[0037] A photoelectric sensor 8 is installed on the track plate 17 at the conveyor end. When the material plate 19 and the sintered bodies on it reach this position, the photoelectric sensor 8 senses the presence of the material and emits a signal. This signal can be used to trigger subsequent operations or control processes, such as stopping the conveyor motor or starting the lifting mechanism.

[0038] At the same time, a safety latch 9 is provided on the fixing seat 11 at the conveying end. When the material plate 19 is in place, the safety latch 9 can be automatically or manually inserted into the corresponding position of the material plate 19 to fix the material plate 19 and prevent it from moving or tipping over during subsequent operations.

[0039] Specifically, as shown in the figure, a fork groove opening upward is formed between the adjacent fixing seats 11 and the bottom plate 12. The utility model can be used in conjunction with a transfer forklift, and the fork of the forklift can be extended into the fork groove to facilitate the removal of the material plate on the transfer device.

[0040] Specifically, as shown in the figure, the material lifting mechanism 2 includes a plurality of worm gear elevators arranged on the frame 3, each of the worm gear elevators includes a worm gear motor 15, a commutator 13 cooperating with the worm gear motor 15, and a screw rod 14 cooperating with the commutator 13, and the top end of the screw rod 14 is fixedly connected to the bottom of the base plate 12.

[0041] The worm gear lift is a widely used mechanical transmission device that uses the meshing of a worm wheel and a worm to achieve the conversion from rotational motion to linear motion. It also has a self-locking function, so that under certain conditions, even if the motor stops working, the lifting platform can remain in its current position without sliding down.

[0042] In the material lifting mechanism 2, the worm gear elevator is installed on the frame 3 and serves as the power source for driving the material conveying mechanism 2 to move up and down. Each worm gear elevator mainly consists of the following parts:

[0043] Worm gear motor 15: As a power source, it provides the necessary torque and speed to drive the entire lifting process.

[0044] Commutator 13: Connects the worm gear motor 15 and the lead screw 14, controlling the lift by changing the direction of rotation of the motor's output shaft or transferring rotational motion to the lead screw. It's important to note that in practice, the term "commutator" may not directly correspond to a specific standard component name. It may refer to a reduction gearbox, coupling, or other similar component that works together to connect and transmit power between the motor and the lead screw.

[0045] Screw 14: Cooperates with commutator 13 to convert rotational motion into linear motion. The top of the screw is fixed to the bottom of base plate 12 of material conveying mechanism 2. Therefore, when the screw moves up and down, it will drive the entire material conveying mechanism 2 up and down.

[0046] This NdFeB sinter transfer device utilizes an efficient material conveying mechanism and a flexible material lifting mechanism to achieve smooth conveying and precise positioning of sintered bodies, while also improving automation. Its compact structure and ease of operation adapt to varying working heights, seamlessly integrating with transfer forklifts, significantly enhances production efficiency and safety.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0048] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
