[0044] 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.

[0045] Example 1:

[0046] like Figures 1-6 As shown, a neodymium iron boron (NdFeB) material can handling mechanism includes:

[0047] Rack 1;

[0048] The transport module 2 is slidably mounted on the frame 1;

[0049] Lifting module 3 is mounted on frame 1;

[0050] Positioning module 4 is mounted on lifting module 3 and is used to connect to material tank 7;

[0051] 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;

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Furthermore, the difference between the two lies in the direction of their movement, such as... Figure 1 and Figure 2 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] It is easy to understand that the neodymium iron boron can handling mechanism can also be used for handling any other suitable existing materials.

[0061] Example 2:

[0062] This embodiment, based on embodiment 1, introduces the lifting module 3 and the positioning module 4, specifically:

[0063] In one possible implementation, the lifting module 3 includes a lifting motor 301, a folding frame 302, a second drive component 303, and a support platform 304.

[0064] The lifting motor 301 is fixed on the sliding frame 202;

[0065] Two folding frames 302 are provided and are arranged opposite to each other and spaced apart on the sliding frame 202. Correspondingly, there is a mounting groove between the two folding frames 302 for installing the tank docking module 5 and the opening and closing module 6.

[0066] The second driving component 303 is mounted on the sliding frame 202 and connected to the output end of the lifting motor 301. Accordingly, the second driving component 303 is used to drive the folding frame 302 to unfold or fold.

[0067] The support platform 304 is connected to the folding frame 302. Accordingly, when the folding frame 302 is unfolded or folded, the support platform 304 moves up and down.

[0068] The conveying module 2 includes a sliding frame, and the components in the lifting module 3 are connected to the sliding frame to realize the connection between the conveying module 2 and the lifting module 3.

[0069] Based on the above design, the lifting motor 301 provides power to the lifting module 3 to enable the unfolding or folding of the folding frame 302. When the folding frame 302 is unfolded, the various rods inside the folding frame 302 rotate vertically, increasing the height of the folding frame 302 and causing the support platform 304 to move upward. Conversely, when the folding frame 302 is folded, the various rods inside the folding frame 302 rotate horizontally, decreasing the height of the folding frame 302 and causing the support platform 304 to move downward. The support platform 304 is used in conjunction with the positioning module 4 to support and secure equipment such as the material tank 7.

[0070] Accordingly, the support platform 304 is constructed as a frame structure to allow the discharge pipe and other equipment of the material tank 7 to pass under the support platform 304 and connect with the inlet pipe of the receiving equipment, thus connecting the two devices. Alternatively, the receiving equipment can also be constructed as an open structure, eliminating the need for pipe connections, making it more convenient to discharge material from the material tank 7. Therefore, the NdFeB material tank handling mechanism can handle both material tanks 7 with and without discharge processes, thus having a wider range of applications.

[0071] Meanwhile, two folding frames 302 are spaced apart to form mounting slots, facilitating the installation of the tank docking module 5 and the opening / closing module 6, such as... Figure 1 and Figure 2 As shown, this also allows the tank docking module 5 and the opening and closing module 6 to be concentrated inside the frame 1, reducing outward protrusion and making the NdFeB tank handling mechanism occupy less space.

[0072] In one possible implementation, the second driving member 303 includes a screw 305, a second transmission plate 306, and a limiting frame 307;

[0073] Screw 305 is connected to the output end of lifting motor 301;

[0074] The second transmission plate 306 has two ends, one end of which is a drive end that is slidably mounted on the screw 305, and the other end is a moving end equipped with a pulley 308.

[0075] The limiting frame 307 is fixed on the sliding frame 202 and is provided with a limiting groove. Correspondingly, the pulley 308 is slidably disposed in the limiting groove.

[0076] Correspondingly, the lower end of the folding frame 302 has two connection points, one of which is hinged to the sliding frame 202, and the other is sleeved on the second transmission plate 306. When the screw 305 rotates, the lower end of the second transmission plate 306 and the folding frame 302 reciprocate along the screw 305 to drive the folding frame 302 to unfold or fold. The pulley 308 slides along the limiting groove to limit the degree of unfolding or folding of the folding frame 302.

[0077] Based on the above design, the second driving component 303 provides power to the lifting module 3. Specifically, after the lifting motor 301 is started, the screw 305 rotates, and the second transmission plate 306 moves along the screw 305 under its drive. A connection point at the lower end of the folding frame 302 is fitted onto the second transmission plate 306. When the second transmission plate 306 moves, this connection point of the folding frame 302 moves accordingly, so that the two connection points of the folding frame 302 move closer or further apart. When the two connection points of the folding frame 302 move closer, the various rods inside the folding frame 302 rotate vertically to achieve raising; when the two connection points of the folding frame 302 move further apart, the various rods inside the folding frame 302 rotate horizontally to achieve lowering.

[0078] Meanwhile, the pulley 308 on the second transmission plate 306 slides within the limiting groove. When the pulley 308 slides to the end of the limiting groove, it is blocked and stops moving. Thus, by limiting the movement range of the second transmission plate 306 through the limiting groove, the probability of the folding frame 302 rising too high and causing structural damage is reduced, which helps to extend the service life of the folding frame 302.

[0079] like Figure 3 As shown, there are two folding frames 302, and two lifting motors 301 and two second drive components 303, with each of the lifting motors 301, folding frames 302, and second drive components 303 arranged in a one-to-one correspondence. Based on this, the two folding frames 302 are powered respectively, enabling the folding frames 302 to be raised and lowered.

[0080] Or, such as Figure 3 As shown, a second drive shaft 309 is provided on each side of the lifting motor 301. Each second drive shaft 309 extends towards one of the folding frames 302 and connects to the second drive member 303. Based on this, by supplying power to the two second drive members 303 through the same lifting motor 301, the synchronicity of the movement of the two folding frames 302 is better, and the lifting is more stable. In addition, as Figure 3 and Figure 4 As shown, there is an angle between the second drive shaft 309 and the screw 305, that is, when steering is involved, the second drive shaft 309 is connected to the screw 305 through the steering gear 310.

[0081] The second transmission plate 306 includes a plate body portion 311 for connecting the screw 305 and a shaft portion 312 for connecting the pulley 308. Correspondingly, the folding frame 302 is connected to the shaft portion 312. Based on this, the plate body portion 311 can be made of channel steel, and the shaft portion 312 can be made of any suitable outer diameter rod.

[0082] The pulley 308 is slidably positioned within the limiting frame 307, but in the event of unexpected disturbance, the pulley 308 may disengage from the limiting groove. Therefore, in one possible implementation, the shaft portion 312 is provided with two limiting members 313 located on either side of the pulley 308. The limiting members 313 act as a stop, ensuring that the pulley 308 remains within the groove.

[0083] like Figure 4 and Figure 5 As shown, the limiting member 313 includes a bearing 314, a base plate 315, a limiting shaft 316, and a limiting wheel 317;

[0084] Bearing 314 is sleeved on shaft portion 312;

[0085] The substrate 315 is parallel to the limiting frame 307. The middle part of the substrate 315 is provided with a mounting hole adapted to the bearing 314. The substrate 315 is also provided with two concave grooves located on both sides of the mounting hole.

[0086] Two limiting shafts 316 are provided and are respectively inserted into the corresponding concave grooves. Both ends of the limiting shafts 316 extend out of the base plate 315. A limiting wheel 317 is rotatably provided at each end of the limiting shafts 316. Correspondingly, the limiting frame 307 is provided with a sub-groove body that is adapted to the limiting wheel 317 and parallel to the limiting groove.

[0087] Based on the above design, when the pulley 308 moves, the limiting member 313 moves accordingly. Specifically, the base plate 315 and the limiting shaft 316 move accordingly, and the limiting wheel 317 slides along the sub-groove. This not only effectively prevents the pulley 308 from coming off, but also works with the limiting groove to guide the direction, ensuring that the second transmission plate 306, pulley 308, folding frame 302 and other components all move in the designed direction.

[0088] In one possible implementation, the positioning module 4 is provided in several parts and is arranged around the support platform 304 to form a positioning groove adapted to the material tank 7.

[0089] Based on the above design, when the material tank 7 is lowered onto the support platform 304, or when the support platform 304 is moved to a predetermined position, if the material tank 7 is in the designed position, it will accurately enter the positioning groove to achieve positioning and ensure the accuracy of subsequent processes. Conversely, if the material tank 7 abuts against the positioning module 4, the position of the material tank 7 will be moved by other equipment until the material tank 7 enters the positioning groove.

[0090] It is easy to understand that, for material tanks 7 of different shapes and sizes, the position of the positioning module 4 can be changed so that the positioning groove can be adapted to the material tank 7, thereby adapting to more different types of material tanks 7 and expanding the scope of use.

[0091] Accordingly, the positioning module 4 includes a base 401 and a support block 402. Two support blocks 402 are provided and are slidably disposed on the base 401. The support blocks 402 are used to support the material tank 7.

[0092] When multiple positioning modules 4 are provided, at least one positioning module 4 is provided with a swing rod 403. Correspondingly, the swing rod 403 is provided and rotatably mounted on the base 401. Correspondingly, a support block 402 is provided on each side of the swing rod 403. The swing rod 403 is used to press down and fix the material tank 7.

[0093] Based on the above design, after the material tank 7 is inserted into the positioning slot, the support block 402 moves and lifts the material tank 7. The support blocks 402 of multiple positioning modules 4 cooperate with each other to lift the material tank 7. Furthermore, by adjusting the specific height of the predetermined position, it is possible to select whether the support platform 304 contacts and lifts the material tank 7, so as to avoid the support block 402 bearing the force alone.

[0094] After the material tank 7 is supported by the support block 402, although the degree of freedom of the material tank 7 in the plane is restricted by the formation of the positioning groove, the material tank 7 is in a free state in the vertical direction. At this time, by rotating and pressing down on the material tank 7 by at least one swing rod 403, the degree of freedom of the material tank 7 is completely restricted, minimizing accidental disturbances to the material tank 7. It is easy to understand that when the material tank 7 is inserted into or disengaged from the positioning groove, the swing rod 403 rotates and disengages to avoid obstructing the movement of the material tank 7; similarly, the support block 402 should also promptly avoid the material tank 7.

[0095] Preferably, the positioning module 4 and the swing rod 403 are symmetrically arranged with the material tank 7 as the center, so that the material tank 7 is evenly stressed and the movement of the material tank 7 is more stable.

[0096] Accordingly, power is provided to the support block 402 and the swing rod 403 by a cylinder or other suitable driving component to achieve the sliding of the support block 402 and the rotation of the swing rod 403.

[0097] In one possible implementation, such as Figure 6 As shown, the base 401 includes a first plate 404, a second plate 405 and a third plate 406;

[0098] The first plate 404 is parallel to the support platform 304;

[0099] The bottom surface of the first plate 404 is connected to the second plate 405 through several fourth plates 407. Correspondingly, the second plate 405 is connected to the support platform 304. A third plate 406 is provided at each end of the top surface of the first plate 404. Correspondingly, the support block 402 is slidably disposed on the third plate 406. A swing rod 403 is installed between the two third plates 406.

[0100] Based on the above design, the first plate 404, the second plate 405, and the fourth plate 407 are constructed as a frame structure to reduce weight. The third plate 406 is used to install the support block 402, so that each positioning module 4 has two support blocks 402 to increase the lifting points in contact with the tank and improve lifting performance. If the positioning module 4 needs to be equipped with a swing rod 403, the swing rod 403 can be installed on the first plate 404.

[0101] Optionally, such as Figure 2 and Figure 3 As shown, a square plate is provided below the material tank 7, and a positioning module 4 is provided on each side of the square plate. Accordingly, there are four positioning modules 4, and two of the opposite positioning modules 4 are provided with swing rods 403.

[0102] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
