[0002] In the production process of sintered neodymium iron boron, the powder after hydrogen crushing will contain a certain amount of hydrogen atoms. Due to the small volume and strong activity of hydrogen atoms, they can easily penetrate between metal atoms and gradually precipitate when the environment changes or the pressure releases. This hydrogen precipitation phenomenon may cause spontaneous combustion when the powder is exposed to air, and even cause deflagration under certain pressure, greatly increasing the operation risk.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0037] Example 1:

[0038] like Figures 1-7 As shown, a neodymium iron boron (NdFeB) material can handling mechanism includes:

[0039] Rack 1;

[0040] The transport module 2 is slidably mounted on the frame 1;

[0041] Lifting module 3 is mounted on frame 1;

[0042] Positioning module 4 is mounted on lifting module 3 and is used to connect to material tank 7;

[0043] The material tank docking module 5 is installed on the handling module 2 and is used to fix and seal the discharge pipe of the material tank 7;

[0044] In addition, the opening and closing module 6 is installed on the conveying module 2 and is used to control the opening and closing of the discharge pipe of the material tank 7.

[0045] In the neodymium iron boron material tank handling mechanism, each functional module is set on the frame 1 so that the functional modules can be linked together and form an organic whole to achieve the designed function. It is easy to understand that the frame 1 can be constructed as any suitable structure.

[0046] Both the conveying module 2 and the lifting module 3 have at least two workstations: one for receiving materials, including but not limited to the material tank 7, and the other for releasing materials, such as the material tank 7 or the material in the material tank 7, to achieve material transfer. Furthermore, the two are interconnected; that is, since the lifting module 3 is mounted on the conveying module 2, their movements are linked, meaning that the movement of the conveying module 2 will drive the movement of the lifting module 3.

[0047] Furthermore, the difference between the two lies in the direction of their movement, such as... Figures 1-3 As shown, the handling module 2 moves within a plane of the frame 1, while the lifting module 3 moves vertically. Based on this, the NdFeB material tank handling mechanism utilizes vertical space to reduce the equipment's footprint and decrease the required factory floor space.

[0048] The positioning module 4 is set on the lifting module 3 and moves up and down with the lifting module 3. When the lifting module 3 moves to one of the work positions, such as the top, the positioning module 4 can contact the material tank 7. At this time, the other equipment can place the material tank 7 on the positioning module 4. The positioning module 4 connects and fixes the material tank 7, and the other equipment detaches from the material tank 7 so that the material tank 7 enters the neodymium iron boron material tank conveying mechanism.

[0049] The discharge pipe of the material tank 7 is used to discharge and guide the material. When the material is discharged from the material tank 7, the discharge pipe is fixed and sealed by the material tank docking module 5 to avoid accidental disturbance. In particular, when the discharge pipe of the material tank 7 is connected to the feed pipe of the receiving equipment, the docking module 5 is used to fix and seal the connection between the discharge pipe and the feed pipe to reduce or even avoid material leakage.

[0050] The opening and closing module 6 is used to control the opening and closing of the discharge pipe of the material tank 7, ensuring that the material tank 7 discharges material only after meeting the design requirements. For example, if the discharge pipe of the material tank 7 is connected to the feed pipe of the receiving equipment, and the material tank connection module 5 is fixed and sealed at the connection between the discharge pipe and the feed pipe, the opening and closing module 6 will then open the discharge pipe to release the material.

[0051] During operation, the material tank 7 moves to the designated position, the lifting module 3 is activated and moves upward to the predetermined position, the positioning module 4 lifts and fixes the material tank 7, and the remaining equipment detaches from the material tank 7. The lifting module 3 then moves downward to the predetermined position until the discharge pipe of the material tank 7 connects with the inlet pipe of the receiving equipment. The material tank docking module 5 is activated to fix and seal the connection between the discharge pipe and the inlet pipe. The opening and closing module 6 is activated to open the discharge pipe of the material tank 7, releasing the NdFeB material. The transport module 2 is activated and drives the various components to move the material tank 7 to the transition point of the next process. Before the material tank 7 detaches from the NdFeB material tank transport mechanism, the positioning module 4, the opening and closing module 6, and the material tank docking module 5 are all reset to disconnect from the material tank 7 and avoid obstructing the transfer of the material tank 7.

[0052] It is easy to understand that the neodymium iron boron can handling mechanism can also be used for handling any other suitable existing materials.

[0053] Example 2:

[0054] This embodiment, based on embodiment 1, describes the tank docking module 5 and the opening / closing module 6. Specifically:

[0055] In a possible implementation, the tank docking module 5 is provided with at least two and arranged around the discharge pipe of the tank 7. Based on the above design scheme, the docking of the discharge pipe and the feeding pipe is fixed and sealed by the cooperation of multiple tank docking modules 5, so as to avoid material leakage or external impurities from entering, and ensure that the purity of the material meets the use requirements.

[0056] Considering the limited space, in general, two tank docking modules 5 are arranged on the two sides of the discharge pipe of the tank 7. In other cases, such as when the diameter of the discharge pipe is large, the number of tank docking modules 5 can be increased.

[0057] Correspondingly, the tank docking module 5 comprises a first mounting frame, a docking seat 501 and a docking piece 502. The first mounting frame is arranged on the sliding frame 202, the docking seat 501 is arranged on the first mounting frame, and one end of the docking piece 502 is slidingly arranged on the docking seat 501. The other end of the docking piece 502 faces the discharge pipe of the tank 7. Correspondingly, the docking piece 502 is provided with an arc-shaped clamping groove 503 adapted to the discharge pipe of the tank 7.

[0058] Based on the above design scheme, the first mounting frame is used to connect the sliding frame 202, so that the tank docking module 5 can move back and forth with the sliding frame 202. Correspondingly, according to the length of the discharge pipe of the tank 7, the height of the first mounting frame is set to ensure that the docking piece 502 can accurately seal the docking position of the discharge pipe and the feeding pipe.

[0059] The docking seat 501 is used to connect the first mounting frame and the docking piece 502. It is easy to understand that the first mounting frame and the docking seat 501 can be respectively constructed as any suitable structure to adapt to different use environments. The docking piece 502 is used to contact the discharge pipe. The docking pieces 502 on the multiple tank docking modules 5 cooperate with each other to form an annular groove adapted to the outer periphery of the discharge pipe, so as to ensure the fixing and sealing effect.

[0060] Optionally, as shown in Figure 4 and Figure 5 The docking seat 501 comprises a bottom plate 504, a first docking plate 505 and a rib plate 506. The bottom surface of the bottom plate 504 is connected to the first mounting frame, the top surface of the bottom plate 504 is connected to the first docking plate 505 and forms an L-shaped plate, the first docking plate 505 is used to connect the docking piece 502, and the rib plate 506 is provided with two and is used to connect the bottom plate 504 and the first docking plate 505. Based on this, the structure of the docking seat 501 is simple, which is convenient for production and manufacturing, and the structural strength is increased by the rib plate 506 to ensure the service life.

[0061] Optionally, as shown in Figure 4 and Figure 5As shown, the docking member 502 comprises a power supply member 507, a second docking plate 508 and a guide rod 509;

[0062] The power supply member 507 is fixed on the first docking plate 505, and the output end of the power supply member 507 penetrates through the first docking plate 505 and is connected to the second docking plate 508, and correspondingly, the power supply member 507 and the second docking plate 508 are arranged on the two sides of the first docking plate 505 respectively;

[0063] The second docking plate 508 has opposite two ends, one of which is connected to the power supply member 507, and the other end is provided with the arc-shaped clamping groove 503;

[0064] The guide rod 509 is slidingly arranged on the first docking plate 505, and the guide rod 509 penetrates through the first docking plate 505 and is connected to the second docking plate 508, and correspondingly, the first docking plate 505 is provided with a guide cylinder 510 matched with the guide rod 509.

[0065] Based on this, the power supply member 507 includes but is not limited to a cylinder or any other suitable driving component, and the power supply member 507 is used to provide power and drive the second docking plate 508 to move reciprocally, so that the second docking plate 508 presses against or leaves the arc-shaped clamping groove 503. At the same time, the movement of the second docking plate 508 is guided by the cooperation of the guide rod 509 and the guide cylinder 510, so as to ensure that the second docking plate 508 moves reciprocally along the designed route.

[0066] In a possible implementation, the opening and closing module 6 comprises a second mounting frame, a third driving member 601 and an opening and closing member 602;

[0067] The second mounting frame is arranged on the sliding frame 202;

[0068] The third driving member 601 is arranged on the second mounting frame, and the output end of the third driving member 601 is connected to the opening and closing member 602 to drive the opening and closing member 602 to move and connect the discharge pipe of the material tank 7;

[0069] The opening and closing member 602 is connected to the third driving member 601, and correspondingly, the opening and closing member 602 is used to control the opening and closing of the discharge pipe of the material tank 7.

[0070] Based on the above design scheme, after the discharge pipe and the feeding pipe are docked, and the material tank docking module 5 is fixed and blocked, the opening and closing module 6 can be started to open the discharge pipe, release the material in the material tank 7, and realize the transfer of the material.

[0071] The second mounting frame is used to connect the sliding frame 202, so that the opening and closing module 6 can move reciprocally with the sliding frame 202. It is easy to understand that the second mounting frame can be constructed as any suitable structure.

[0072] The third driving member 601 is used to control the position of the opening and closing member 602. When the opening and closing member 602 moves and connects the discharge pipe of the material tank 7, specifically, connects the valve rod on the discharge pipe, the opening and closing member 602 acts and drives the valve rod to rotate, so as to open the discharge pipe. Conversely, when the third driving member 601 drives the opening and closing member 602 to be separated from the valve rod, the material tank 7 is facilitated to move relative to the opening and closing module 6.

[0073] In a possible implementation, the third driving member 601 includes a base frame 603, a first driving device 604 and a second driving device 605. The base frame 603 is slidably arranged on the second mounting frame through the first driving device 604. Correspondingly, the first driving device 604 is used to drive the base frame 603 to move. The second driving device 605 and the opening and closing member 602 are arranged on the base frame 603. Correspondingly, the second driving device 605 is used to drive the opening and closing member 602 to move.

[0074] The opening and closing member 602 includes an opening and closing motor 606, a third transmission plate 607 and an opening and closing block 608. The opening and closing motor 606 is arranged on the base frame 603 and connected with the output end of the second driving device 605. The third transmission plate 607 connects the opening and closing motor 606 and the opening and closing block 608. The opening and closing block 608 is provided with an inner groove 609 for connecting the valve rod of the discharge pipe.

[0075] Correspondingly, when the valve rod of the discharge pipe is inserted into the inner groove 609, the opening and closing block 608 is driven to rotate by the opening and closing motor 606, so as to drive the valve rod to rotate and control the opening and closing of the discharge pipe.

[0076] Based on the above design scheme, the first driving device 604 is used to drive the base frame 603 to move on the second mounting frame. The second driving device 605 is used to drive the opening and closing member 602 to move on the base frame 603. The base frame 603 and / or the opening and closing member 602 are moved to achieve the purpose of controlling the relative distance between the opening and closing member 602 and the valve rod.

[0077] Specifically, as shown in Figure 6 and Figure 7 When the opening and closing member 602 connects the valve rod, the first driving device 604 is started and drives the base frame 603 to move towards the valve rod until the opening and closing member 602 is side by side with the valve rod. The first driving device 604 is stopped, and the second driving device 605 is started. The opening and closing member 602 moves towards the valve rod until the valve rod is arranged on the inner groove 609. At this time, if it is needed to open the discharge pipe, the opening and closing motor 606 is started to drive the third transmission plate 607 and the opening and closing block 608 to rotate, so as to drive the valve rod to rotate and open the discharge pipe. Conversely, the first driving device 604 and the second driving device 605 cooperate with each other to move the opening and closing member 602 away from the valve rod.

[0078] It is easy to understand that the first driving device 604 and the second driving device 605 are selected from any suitable existing single-axis moving device, which has a wide selection range and good practicability.

[0079] For the opening and closing member 602, the third transmission plate 607 and the opening and closing block 608 are driven to rotate by the opening and closing motor 606, and if the opening and closing block 608 is connected to the valve rod, the valve rod can be rotated and the opening and closing of the discharge pipe can be controlled. It is easy to understand that the opening and closing motor 606 can be selected from any suitable existing model, and the third transmission plate 607 can be constructed in any suitable shape.

[0080] For the opening and closing block 608, as shown in Figure 6 and Figure 7 At least one spring 610 is provided on the opening and closing block 608, and the two ends of the spring 610 are connected to an additional plate 611, respectively. Correspondingly, two additional plates 611 are provided on the third transmission plate 607, and the opening and closing block 608 and the spring 610 are located between the two additional plates 611.

[0081] Therefore, the spring 610 plays a buffering role, reducing the impact force when the opening and closing block 608 is connected to the valve rod, and plays a protective role. Generally, two springs 610 are provided and arranged side by side, or the number of springs 610 is appropriately increased according to the actual use condition.

[0082] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
