Technical Field

[0001] The invention relates to the technical field of rare earth processing, and in particular to automatic feeding equipment for rare earth permanent magnet processing. Background Art

[0002] In the production process of rare earth permanent magnet materials, processing and molding is a crucial link. Rare earth permanent magnet materials, with their excellent magnetic properties, are widely used in electronic information, new energy, aerospace and other fields. However, in the current rare earth permanent magnet processing and molding process, a significant challenge is to accurately and efficiently place the rare earth powder in a specific mold.

[0003] Traditional processing and molding methods often rely on manual operation. Workers need to manually fill rare earth powder into the mold, a process that is not only inefficient but also difficult to ensure quality control. Due to the particularity of rare earth powder, factors such as its particle size, distribution, and filling density will directly affect the magnetic properties of the final product. Therefore, manual operation often cannot ensure the consistency and accuracy of each filling, resulting in uneven product quality.

[0004] What is more serious is that rare earth powders pose a certain threat to the health of workers. Some components of rare earth elements are potentially toxic, and long-term contact or inhalation of these powders may cause damage to the respiratory system, skin, etc. of workers. In addition, the fine particles of rare earth powders are easily suspended in the air, increasing the risk of inhalation by workers.

The middle part of the moving seat 4 is penetrated and provided with a support platform 8. The pressing block 9 is longitudinally slidably connected in the support platform 8. The transmission shaft 10 is horizontally rotatably connected to the bottom of the moving seat 4. The middle part of the transmission shaft 10 is A transmission gear 1001 is fixedly connected, a rack 901 is arranged at the lower end of the pressing block 9 to mesh with the transmission gear 1001, the clamping support 12 is symmetrically fixed to the moving seat 4, the screw 13 is rotatably connected in the clamping support 12, the clamping block 14 is limited and slidable on the clamping support 12 and is connected to the screw 13 by a thread, the transmission shaft 10 transmits the screw 13 through the speed increase pulley group 11 at the end, and the vibration mechanism includes a crank shaft 19 and a knocking block 21, and the knocking block 21 is slidably connected to the outer frame 1 The crank shaft 19 connected to the inside of the external frame 1 is rotated to continuously push the knocking block 21. The mold is placed on the pressing block 9 and pressed downward. The rack 901 drives the transmission gear 1001 to rotate, and then drives the transmission shaft 10 to rotate. The transmission shaft 10 drives the screw 13 to rotate and then pushes the clamping block 14 to move towards each other. The clamping block 14 can clamp and fix the mold. The moving seat 4 moves to the bottom of the hopper 3 for loading. The knocking block 21 knocks and vibrates the moving seat 4 to form the rare earth powder in the mold.

[0030] like Figure 6 and Figure 7As shown, the vibration mechanism also includes a guide rod 20, an offset gear set 2001 and a spline shaft 2003. The guide rod 20 is slidably connected to the inner wall of the external frame 1. A spring is connected between the guide rod 20 and the external frame 1. The right end of the guide rod 20 is rotatably connected to the spline shaft 2003. The crank shaft 19 slides with the spline shaft 2003 through a spline groove. The crank shaft 19 can contact and push the knocking block 21. The threaded rod 7 transmits the crank shaft 19 through the offset gear set 2001. A right-angle bending portion 2002 is provided at the end of the guide rod 20. The moving seat 4 can contact and push the bending portion 2002 of the guide rod 20. The offset gear set 2001 consists of two gears, one of which is connected to the end of the rear threaded rod 7 by a key, and the other is connected to the rear end of the threaded rod 7 by a key. The gear is fixed to the end of the spline shaft 2003. When the moving seat 4 moves to the right to the bottom of the hopper 3 for loading, the moving seat 4 can contact and push the bent portion 2002 of the guide rod 20, and then push the guide rod 20 to the right, thereby pushing the spline shaft 2003 to the right, and then the two gears of the offset gear set 2001 will engage with each other, and then the threaded rod 7 will transmit the crank shaft 19. During the rotation of the crank shaft 19, the knocking block 21 will continue to be pushed, and the knocking block 21 can transmit the movement seat 4. At this time, the clamping block 14 and the clamping claw 15 clamp and fix the mold, and the vibration of the knocking block 21 can be continuously transmitted to the mold. When the rare earth powder in the hopper 3 falls into the mold, the knocking block 21 can vibrate the rare earth powder to accelerate its shaping.

[0031] like Figure 4 As shown, it also includes a guide block 401 and a balance bar 402. The balance bar 402 is set at the bottom of the moving seat 4. The guide block 401 is slidably connected in the balance bar 402. A spring is connected between the guide block 401 and the balance bar 402. The moving seat 4 is threadedly connected to the threaded rod 7 through the guide block 401. The guide block 401 and the balance bar 402 are set to provide a distance for the moving seat 4 to move forward and backward, thereby providing spatial conditions for the vibration of the moving seat 4.

[0032] like Figure 3 and Figure 4 As shown, it also includes a clamping jaw 15 and a reset spring 1501. The clamping jaw 15 is slidably connected in the clamping block 14. The reset spring 1501 is connected between the clamping jaw 15 and the clamping block 14. A rubber block is arranged at the opposite end of the clamping jaw 15.

[0033] like Figure 5As shown, it also includes a baffle plate 16, a synchronous gear set 17, a push rod 18 and a wedge contact block 1801. A rotatably connected baffle plate 16 is provided at the bottom of the hopper 3, specifically four baffles arranged horizontally. The rotating shaft of the baffle plate 16 is connected to the synchronous gear set 17. The push rod 18 is slidably connected in the external frame 1. The push rod 18 can be adaptively extended and retracted in the vertical direction. The upper end of the push rod 18 is connected to the synchronous gear set 17, and the lower end is located on the inner side of the external frame 1. The lower end of the push rod 18 is connected to the wedge contact block 1801. The moving seat 4 can contact and push the wedge contact block 1801. A spring is connected between the wedge contact block 1801 and the external frame 1. The moving seat 4 moves to the right to the bottom of the closed bin 2. The moving seat 4 contacts and pushes the inclined surface of the wedge head contact block 1801, thereby pushing the push rod 18 backward. Since the synchronous gear set 17 is composed of four mutually meshing gears, and the upper end of the push rod 18 is connected to the eccentric point of the separated gears, the push rod 18 can drive the synchronous gear set 17 to rotate, and then drive the baffle plate 16 to rotate and open, and the rare earth powder in the hopper 3 falls into the mold of the moving seat 4, realizing the effect of automatic loading. After the loading is completed, the driving assembly controls the moving seat 4 to move to the left. After the moving seat 4 disengages from the wedge head contact block 1801, the wedge head contact block 1801 moves forward and resets under the action of the spring, and the push rod 18 therefore drives the synchronous gear set 17 to rotate and reset, that is, drives the baffle plate 16 to rotate and close.

[0034] like Figure 8 As shown, it also includes a second motor 22 and a rolling roller 23. The rolling roller 23 is rotatably connected in the hopper 3, specifically located above the material baffle plate 16. The rolling roller 23 is provided with rolling teeth 2301 on the outside. The second motor 22 supplies energy to the rolling roller 23. The second motor 22 is fixed to the side wall of the hopper 3. The output shaft of the second motor 22 is connected to the rolling roller 23 through a coupling. The two rolling rollers 23 are driven by mutually meshing gears.

[0035] like Fig. 9 As shown, it also includes a limiting block 24, which is fixed to the moving seat 4. The limiting block 24 can limit the front and rear sides of the mold to improve the accuracy of the staff in placing the mold.

[0036] like Fig. 9 As shown, it also includes a roller 25, which is arranged in the base 8. The roller 25 can reduce the friction coefficient between the mold and the base 8. Therefore, even if the staff does not place the mold in the middle of the pressing block 9, the clamping block 14 can still push the mold to the specified position in the middle of the base 8 with the help of the roller 25, providing a guarantee for subsequent accurate loading.

[0037] The working principle of the embodiment of the present invention is as follows: the staff places the mold on the pressing block 9 and presses it downward until the mold contacts the support platform 8. During this period, the limit block 24 can limit the front and rear sides of the mold, reducing the workload of the staff to align the mold. During the downward movement of the pressing block 9, the rack 901 at the bottom of the pressing block 9 drives the transmission gear 1001 to rotate, thereby driving the transmission shaft 10 to rotate, and the transmission shaft 10 drives the screw rod 13 to rotate and then pushes the clamping block 14 to move toward each other. The clamping block 14 can clamp and fix the mold. The support platform 8 is provided with a roller 25 to improve the mobility of the mold, that is, when the mold is not located in the middle of the support platform 8, the clamping block 14 can still push the mold to the accurate At the loading position, a clamping jaw 15 with a rubber head is provided in the clamping block 14, and the clamping jaw 15 can firmly clamp the mold, and then the first motor 5 is turned on to drive the threaded rod 7 to rotate, and the threaded rods 7 are transmitted through the transmission belt 6, and the threaded rod 7 can drive the moving seat 4 to move to the right, and the moving seat 4 moves to the right to the bottom of the closed bin 2, and the moving seat 4 contacts and pushes the inclined surface of the wedge head contact block 1801, so that the push rod 18 can be pushed backward. Because the synchronous gear set 17 is composed of four mutually meshing gears, and the upper end of the push rod 18 is connected to the eccentric part of the separated gears, the push rod 18 can drive the synchronous gear set 17 to rotate, and then drive the baffle plate 16 to rotate. The hopper 3 is automatically opened, and the rare earth powder in the hopper 3 falls into the mold of the moving seat 4, realizing the effect of automatic feeding. At the same time, the moving seat 4 can contact and push the bent portion 2002 of the guide rod 20, thereby pushing the guide rod 20 to the right, thereby pushing the spline shaft 2003 to the right, and then the two gears of the offset gear set 2001 will mesh with each other, and then the threaded rod 7 will transmit the crankshaft 19. During the rotation of the crankshaft 19, the knocking block 21 will continue to be pushed, and the knocking block 21 can transmit the movement The seat 4, because at this time the clamping block 14 and the clamping claw 15 clamp and fix the mold, the vibration of the knocking block 21 can be continuously transmitted to the mold, when the rare earth powder in the hopper 3 After the powder falls into the mold, the knocking block 21 can vibrate the rare earth powder to accelerate its shaping. After the loading is completed, the driving assembly controls the moving seat 4 to move to the left. After the moving seat 4 disengages from the wedge head contact block 1801, the wedge head contact block 1801 moves forward and resets under the action of the spring, and the push rod 18 therefore drives the synchronous gear set 17 to rotate and reset, that is, drives the baffle plate 16 to rotate and close, and the guide rod 20 will also move to the left and reset under the action of the spring, and the misaligned gear set 2001 will no longer transmit, and the vibration mechanism stops working. When the moving seat 4 moves to the left end of the external frame 1, the staff will take out the mold containing the formed rare earth, and then put in the empty mold to repeat the above actions.
