Description

Technical Field

[0001] The present invention relates to the technical field of magnet processing, and in particular to a grain boundary doping control method and equipment thereof. Background Art

[0002] Grain boundaries are the contact interfaces between grains. The structure, composition and number of grain boundaries have a significant impact on the various properties of metals and various processes within metals. NdFeB is a tetragonal crystal. When PVD coating is performed (i.e., the surface grain boundaries), it is mostly coated by a vacuum ion coating machine.

[0003] For example, Chinese patent publication number CN114855141A discloses a grain boundary diffusion system and method based on NdFeB PVD coating, wherein the inner wall of the hanging rod is symmetrically fixedly sleeved with a collar, the second extrusion rod and the opposite end of the first extrusion rod are fixedly connected with a magnet, the inner cavity of the sliding block, hanging rod and collar is slidably sleeved with the second extrusion rod, and a second spring is fixedly connected between the bottom of the second extrusion rod and the inner cavity of the hanging rod. The grain boundary diffusion system and method based on NdFeB PVD coating solves the problem that when the NdFeB coating that cannot be hung needs to be replaced with a matching hanging rod for clamping, which makes it more troublesome to replace.

[0004] When the device is in use, the workpiece is hung on the hook for processing, but the surface of the workpiece close to the hanging rod cannot be processed due to the obstruction of the hanging rod, and thus the processing effect of the workpiece cannot be guaranteed, the demand for grain boundary regulation cannot be met, and there are certain limitations in use.

DETAILED DESCRIPTION

[0035] Embodiment 1:

[0036] See also Figure 1 to Figure 2An embodiment of the present invention provides a grain boundary doping control device, which is mainly used to improve the coating effect and thus ensure the grain boundary doping control effect. The device includes a coating machine 1 and a shell 2 arranged on the coating machine 1. Two support components 3 are arranged inside the shell 2. The support component 3 includes three vertical tubes 303, a total of six vertical tubes 303, and the whole is arranged in a ring array along the inner wall of the shell 2 (the shell 2 is circular). On this basis, the six vertical tubes 303 of the two support components 3 are also arranged in sequence in an alternating manner, that is, the adjacent two sides of the vertical tube 303 of one support component 3 are respectively the two vertical tubes 303 of another support component 3. Eight inclined frames 4 for hanging workpieces are provided on the six vertical tubes 303. The inclined frames 4 are inclined upward for hanging workpieces, and the eight inclined frames 4 are symmetrically arranged based on the outer surface of the vertical tube 303. The eight inclined frames 4 on a single vertical tube 303 are arranged in sequence in the up and down directions, and the inclined frames 4 on two adjacent vertical tubes 303 are staggered in the up and down directions, so that the four inclined frames 4 on one side of the vertical tube 303 correspond to the four inclined frames 4 on the corresponding side of the adjacent vertical tube 303 on one side and are offset up and down, and the four inclined frames 4 on the other side of the vertical tube 303 correspond to the four inclined frames 4 on the corresponding side of the adjacent vertical tube 303 on the other side and are offset up and down; a number of inclined frames 4 located on the two supporting assemblies 3 are arranged in a circular array along the inner wall of the shell 2, so that the inclined frames 4 on the two supporting assemblies 3 are oriented in corresponding directions.

[0037] A control component 5 for driving all vertical tubes 303 to rotate is also provided inside the shell 2. The lowest inclined frame 4 is fixedly installed between the corresponding vertical tube 303 so that the lowest inclined frame 4 remains tilted upwards unchanged. A connecting member 9 is commonly provided between each of the remaining inclined frames 4 and the control component 5 as well as the corresponding vertical tube 303. The supporting of the inclined frame 4 on the vertical tube 303 is achieved through the connecting member 9. The connecting member 9 cooperates with the vertical tube 303 and the control component 5 so that in the initial state, the remaining inclined frames 4 remain synchronously tilted upwards with the lowest inclined frame 4 to facilitate the placement of the workpiece.

[0038] After the workpieces are placed along the inclined frame 4, start the coating machine 1, the control component 5 and the support component 3 provided with the uppermost inclined frame 4 (for the convenience of description, the support component 3 provided with the uppermost inclined frame 4 is defined as the first support component 3, and the support component 3 provided with the lowermost inclined frame 4 is defined as the second support component 3). The control component 5 can drive the workpiece to revolve and rotate along the inner wall of the shell 2, and the vertical tube 303 drives the inclined frame 4 to move synchronously during the revolution and rotation to ensure the coating effect. The first supporting assembly 3 can drive the corresponding three vertical tubes 303 and the inclined frames 4 to descend vertically. When the vertical tube 303 descends, the inclined frames 4 on the three vertical tubes 303 are driven to rotate toward the inner bottom wall direction of the shell 2 through the connecting piece 9 (the inclined frames 4 on the right side of the vertical tube 303 rotate clockwise, and the inclined frames 4 on the left side rotate counterclockwise). After rotation, the inclined frames 4 on the three vertical tubes 303 can correspond to the inclined frames 4 on the adjacent vertical tubes 303 (the adjacent vertical tubes 303 are on the second supporting assembly 3). At this time, the inclined frames 4 on the three vertical tubes 303 can automatically slide onto the inclined frames 4 on the adjacent vertical tubes 303 (at this time, the inclined frames 4 on the three vertical tubes 303 are no longer hung with workpieces, while the inclined frames 4 on the adjacent vertical tubes 303 are hung with two workpieces. At this time, all the workpieces on the first supporting assembly 3 are transferred to the second supporting assembly 3).

[0039] Then the first support assembly 3 rises and resets, the second support assembly 3 drives the remaining three vertical tubes 303 to descend, and drives the inclined frames 4 of the three vertical tubes 303 to rotate through the connecting piece 9 so that the two workpieces on the inclined frames 4 automatically slide down to the inclined frames 4 on the adjacent vertical tubes 303 (at this time, the workpieces on the second support assembly 3 are all transferred to the first support assembly 3), and so on. In this process, the lowest inclined frame 4 remains tilted upward and always receives the workpieces transferred from the adjacent vertical tubes 303 until all the workpieces slide down to the lowest inclined frame 4. The final situation is that the six inclined frames 4 arranged at the bottom are full of workpieces, while there are no workpieces on the inclined frames 4 arranged upward.

[0040] The surface of the shell 2 is also hinged with a sealing door (not shown in the figure), and when the workpieces are placed on the inclined frame 4 in sequence, the sealing door can be closed for processing by the coating machine 1. In this embodiment, the coating machine 1, the shell 2 and the sealing door are all existing mature technologies and are not described in detail here.

[0041] See also Figures 1 to 5In this embodiment, preferably: the support assembly 3 also includes a cylinder 301 that is slidably engaged with the inner top wall of the shell 2, and a pressure plate 302 that is rotatably connected to the corresponding three vertical pipes 303 is fixedly installed at the output end of the cylinder 301, and the pressure plates of the two support assemblies 3 are symmetrically arranged to avoid interference. Specifically, the sliding engagement between the cylinder 301 and the shell 2 can be achieved through a guide rail and an annular groove (not shown in the figure), the annular groove is opened on the inner top wall of the shell 2 and the guide rail is fixedly installed on the top of the cylinder 301, and the cylinder 301 can be rotated along the inner top wall of the shell 2 through the guide rail and the annular groove, and when the vertical pipe 303 rotates, the pressure plate 302 and the cylinder 301 can be driven to move synchronously; and the cylinder 301 will not fall off from the shell 2, and the two cylinders 301 can share one annular groove.

[0042] In the above structure, the height of the vertical pipe 303 of the first support assembly 3 (with the uppermost inclined frame 4) in the housing 2 is higher than that of the vertical pipe 303 of the second support assembly 3 (with the lowermost inclined frame 4), so that the first support assembly 3 will not interfere with the pressure plate 302 and the vertical pipe 303 of the second support assembly 3 when driving the vertical pipe 303 to descend, and there is a gap between all the vertical pipes 303 and the inner bottom wall of the housing 2. Of course, the cylinder 301 here can also be replaced by an electric push rod, as long as the vertical reciprocating motion of the pressure plate 302 can be achieved.

[0043] Furthermore, the control component 5 includes a motor 501 and a gear plate 502 fixedly connected to the inner wall of the shell 2. The output shaft of the motor 501 is fixedly installed with a partition 504 for rotating the six vertical tubes 303. The top of the partition 504 is rotatably installed with a gear 503 that meshes with the gear plate 502 and is assembled with the vertical tube 303 in a key-shaft manner. The key-shaft assembly allows the vertical tube 303 to slide up and down based on the gear 503. At the same time, the gear 503 can also drive the vertical tube 303 to rotate based on the partition 504, and the partition 504 can drive the vertical tube 303 to revolve. The connecting piece 9 is also arranged on the gear 503. When the vertical tube 303 moves up and down, it is misaligned with the gear 503 in the up and down direction, and then the corresponding inclined frame 4 is driven to rotate through the connecting piece 9.

[0044] Furthermore, the connecting member 9 includes a support rod 901 rotatably mounted on the vertical tube 303, a slider 902 slidably matched with the top of the inclined frame 4, and a first pull rope 903 fixedly connected to the gear 503. Except for the lowest inclined frame 4, the remaining inclined frames 4 are rotatably mounted on the corresponding support rods 901. When the inclined frame 4 rotates toward the inner bottom wall of the shell 2 based on the support rod 901, the slider 902 will automatically slide down due to gravity and counteract the inclined frame 4 on the adjacent vertical tube 303, so that the workpiece on one inclined frame 4 can be smoothly slid onto the inclined frame 4 of the adjacent vertical tube 303 through the slider 902; the lowest inclined frame 4 does not need to be provided with a slider 902, and the slider 902 provided on the corresponding inclined frame 4 will not affect the placement of the workpiece. A second pull rope 904 fixedly connected to the first pull rope 903 is fixedly wound on the outer surface of the support rod 901. When the vertical tube 303 descends relative to the gear 503, the first pull rope 903 can be pulled, and the first pull rope 903 in turn pulls the second pull rope 904, so that the support rod 901 drives the diagonal frame 4 to start rotating (clockwise on the right side and counterclockwise on the left side).

[0045] In order to ensure that the support rod 901 drives the inclined frame 4 to tilt upward and reset, a torsion spring (not shown in the figure) can be sleeved on the outer surface of the support rod 901, and the end of the inclined frame 4 close to the corresponding vertical pipe can also be chamfered to avoid interference with the outer surface of the vertical pipe 303 during rotation. At the same time, a guide column 8 for guiding the first pull rope 903 can be rotatably installed inside the vertical pipe 303, so that the first pull rope 903 can be stably pulled when the vertical pipe 303 descends relative to the gear 503.

[0046] When in use, the workpiece is hung on each inclined frame 4 in turn, while the lowest inclined frame 4 does not need to be hung, and then the coating machine 1 and the motor 501 are started. The motor 501 drives the vertical tube to revolve and rotate in the shell 2 through the gear plate 502, the partition plate 504 and the gear 503, and the coating machine 1 starts processing. At this time, the surface of the workpiece away from the corresponding vertical tube 303 can be processed, while the surface of the workpiece close to the corresponding vertical tube 303 will be blocked due to the correspondence between the two and cannot be fully processed. During the processing, the first support assembly 3 is started to drive the corresponding three vertical tubes 303 to descend. When the three vertical tubes 303 descend based on the gear 503, the first pull rope 903, the second pull rope 904 and the support rod 901 drive the inclined frame 4 to rotate toward the adjacent vertical tube 303 (on the second support assembly 3). Finally, the inclined frames 4 on the three vertical tubes 303 correspond to the inclined frames 4 on the adjacent vertical tubes 303, and the slider 902 automatically slides due to gravity to collide with the inclined frames 4 on the adjacent vertical tubes 303. At this time, the workpiece on the inclined frame 4 of the first support assembly 3 automatically slides to the inclined frame 4 of the second support assembly 3. At this time, the surface of the workpiece on the first support assembly 3 that was originally blocked can be exposed to the outside due to the inclined frame 4 of the second support assembly 3, and the surface of the workpiece that was originally exposed on the outside is blocked corresponding to the workpiece on the second support assembly 3 (at this time, the surface exposed on the outside has been processed, so there is no impact). At this time, there is no workpiece on the inclined frame 4 of the first supporting assembly 3 , there is one workpiece on the lowest inclined frame 4 of the second supporting assembly 3 , and there are two workpieces on the remaining inclined frames 4 of the second supporting assembly 3 .

[0047] Next, the first support assembly 3 drives the three vertical tubes 303 to rise and reset. When the vertical tubes 303 rise based on the corresponding gears 503, the torsion springs make the inclined frame 4 rotate in the opposite direction to reset, and the first pull rope 903 and the second pull rope 904 are also automatically reset. At this time, the second support assembly 3 starts to drive the remaining three vertical tubes 303 to descend. When these three vertical tubes 303 descend, they also drive the inclined frame 4 to rotate correspondingly toward the adjacent vertical tubes 303 (on the first support assembly 3), and the slider 902 is used to make the workpiece of the inclined frame 4 on the second support assembly 3 slide to the inclined frame 4 of the first support assembly 3, so that the side of the workpiece of the inclined frame 4 on the second support assembly 3 that was originally blocked can be turned to be exposed to the outside; at this time, there is no workpiece on the second support assembly 3, and the inclined frames 4 of the first support assembly 3 except the top inclined frame 4 have two workpieces. Then the second support assembly 3 drives the vertical tubes 303 to rise and reset, and the inclined frames 4 on these three vertical tubes also rotate in the opposite direction to reset.

[0048] As this process is repeated, the workpieces are transferred to the inclined racks 4 on the two adjacent vertical tubes 303 in sequence, and the surfaces exposed to the outside are changed in sequence to provide corresponding processing for the coating machine 1. In this process, the lowest inclined rack 4 remains tilted upward and always receives workpieces from the adjacent vertical tubes 303. Eventually, all the workpieces are collected on the lowest inclined rack 4, while the other inclined racks 4 above the lowest inclined rack 4 are empty.

[0049] Furthermore, a stepping mechanism (not shown in the figure) can be installed on the top inclined frame 4, and multiple workpieces can be hung on the top inclined frame 4 during operation. Every time the top inclined frame 4 rotates back and forth once, the stepping mechanism can move a workpiece to the processing position of the top inclined frame 4 and move it away as the top inclined frame 4 rotates. At this time, the continuous processing of the workpiece can be guaranteed, and more workpieces can be placed at one time; among them, the stepping mechanism is a mature technology and will not be described in detail here.

[0050] In summary, through the coordination of structures such as the vertical tube 303, the gear 503, the first pull rope 903 and the slider 902, the workpiece is transferred back and forth between the inclined frames 4 on two adjacent vertical tubes. During the transfer process, the surface of the workpiece exposed to the outside can be changed. With the vertical tube 303 driving the revolution and rotation of the inclined frame 4, all surfaces of the workpiece can be effectively processed, thereby ensuring the doping control effect. After the transfer, the workpiece will all fall onto the lowest inclined frame 4, which is convenient for the staff to quickly unload, improves the overall work efficiency, and is more practical.

[0051] Embodiment 2:

[0052] See also Figures 1 to 6 On the basis of the first embodiment, in order to ensure the stable transfer of the workpiece between the two inclined frames 4, the surface of the slider 902 is provided with a rotating component 6 flush with the top of the inclined frame 4; when the slider 902 is hidden in the inclined frame 4, the rotating component 6 is also synchronously retracted in the inclined frame 4, which will not affect the placement of the workpiece on the inclined frame 4. When the slider 902 slides out relative to the inclined frame 4 due to gravity, the rotating component 6 can automatically open and keep flush with the end of the corresponding inclined frame 4 on the adjacent vertical tube 303, so that the workpiece can slide smoothly from one inclined frame 4 to another inclined frame 4 through the slider 902.

[0053] See also Figures 1 to 7 In this embodiment, preferably: the rotating assembly 6 includes two side plates 601 that are rotatably connected to the slider 902 and are symmetrically arranged, and the second spring 602 is commonly arranged on the opposite side of the two side plates 601. The second spring 602 is not connected to the two side plates 601, but is in a contact and extrusion state. Specifically, a through hole 401 is opened on the surface of the slider 902 for placing the second spring 602.

[0054] In the above structure, the top of the side panel 601 is kept flush with the top of the inclined frame 4. Of course, the top of the slider 902 and the side panel 601 may be lower than the top of the inclined frame 4. In the initial state, the side panel 601 is synchronously hidden in the inclined frame 4 along with the slider 902. When the slider 902 slides out, under the action of the second spring 602, the two side panels 601 open to both sides based on the slider 902. At this time, the end of the side panel 601 away from the slider 902 corresponds to the front / rear side of the inclined frame 4 on the adjacent vertical tube 303.

[0055] When in use, the vertical tube 303 is driven to revolve and rotate by itself through the gear plate 502 and the gear 503 and other structures, and the workpiece is driven to move synchronously. The workpiece is driven to transfer between two corresponding inclined frames 4 of adjacent vertical tubes 303 through the gear 503, the first pull rope 903 and the second pull rope 904 and other structures. The working process and effect of this part are the same as those in the first embodiment, and are not repeated here. The difference is that: when the inclined frame 4 rotates relative to the vertical tube 303, the slider 902 slides based on the inclined frame 4, and finally the slider 902 slides out from the corresponding inclined frame 4 and drives the two side plates 601 and the second spring 602 to move synchronously; when the side plates 601 slide out from the inclined frame 4, the two side plates 601 open to both sides under the action of the second spring 602, and the ends of the two side plates 601 away from the inclined frame 4 correspond to the front and rear sides of the inclined frame 4 on the adjacent vertical tube 303, respectively. At this time, the workpiece can slide smoothly along the slider 902 to the inclined frame 4 of the adjacent vertical tube 303. When the inclined frame 4 rotates in the opposite direction relative to the vertical tube 303 to reset, the slider 902 will automatically reset along the inclined frame 4 due to gravity. The inclined frame 4 squeezes the side plates 601 to restore the two side plates 601 and the slider 902 to the closed state and are retracted into the inclined frame 4 together.

[0056] Furthermore, in order to ensure that the side plate 601 and the slider 902 can be closed smoothly, an inclined track can be set inside the slider 902, and a push rod can be slidably installed in the track (the track and the push rod are not shown in the figure); when the slider 902 slides out from the inclined frame 4 and downward, the push rod can slide along the inclined track and push the side plate 601 to open, and when the slider 902 slides into the inclined frame 4 and moves downward relative to the inclined frame 4, the push rod can slide in the opposite direction along the inclined track and pull the side plate 601 and the slider 902 to close. There is no need to set a second spring 602 here, and it is only necessary for the track to be inclined to point to the side of the side plate 601 away from the slider 902.

[0057] In the first embodiment, the transfer of the workpiece is achieved by the movement of the slider 902 relative to the inclined frame 4. However, since the overall size of the slider 902 is smaller than the inclined frame 4, the end of the slider 902 away from the inclined frame 4 cannot completely correspond to the corresponding end of the other inclined frame 4 on the adjacent vertical tube 303, so that the workpiece may be stuck at the junction of the slider 902 and the other inclined frame 4 when sliding along the slider 902, and the smooth transfer of the workpiece cannot be completed. There are certain limitations in use.

[0058] Compared with the first embodiment, through the cooperation of structures such as the slider 902, the inclined frame 4 and the side plate 601, when the slider 902 slides out relative to the inclined frame 4, the two side plates 601 can automatically open to both sides, corresponding to the front and rear sides of the end of the other inclined frame 4, so that the workpiece can be smoothly slid onto the other inclined frame 4 along the slider 902, ensuring the stable transfer of the workpiece; the overall solution utilizes the sliding of the slider 902 relative to the inclined frame 4, and will not affect the rotation of the inclined frame 4 relative to the vertical tube 303, and is more applicable.

[0059] Embodiment three:

[0060] See also Figures 1 to 8 On the basis of the second embodiment, in order to further ensure the stable transfer of the workpiece between the two inclined frames 4, a limiting assembly 7 fixedly connected to the side plate 601 is provided at the top of the inclined frame 4, and a groove 402 for the placement of the limiting assembly 7 is also opened at the top of the inclined frame 4; when the side plate 601 is opened to both sides, the limiting assembly 7 can be driven to rotate and hide in the groove 402; when the side plate 601 and the slider 902 are closed and hidden in the inclined frame 4, the limiting assembly 7 can be rotated to form a certain angle with the top of the inclined frame 4, thereby realizing the limitation of the workpiece.

[0061] See also Figures 1 to 10 In this embodiment, preferably, the limiting assembly 7 includes a round rod 701 rotatably mounted in the groove 402, a stopper 703 for limiting the workpiece is fixedly mounted on the outer surface of the round rod 701, and a third pull rope 702 fixedly connected to the side plate 601 is fixedly wound on the outer surface of the workpiece. When the side plate 601 is opened relative to the slider 902, the third pull rope 702 is pulled so that the round rod 701 drives the stopper 703 to rotate counterclockwise and hide in the groove 402 ( Fig.10 viewing angle).

[0062] In order to realize the reverse rotation and reset of the round rod 701 and the stopper 703, a torsion spring (not shown in the figure) is also sleeved on the outer surface of the round rod 701. Under the action of the torsion spring, the baffle plate and the top of the inclined frame 4 are roughly kept in a vertical state. When the workpiece is placed, it will automatically slide down along the inclined frame 4 due to gravity. At this time, the workpiece can push the stopper 703 to rotate counterclockwise to allow the workpiece to pass. Then the workpiece moves to between the stopper 703 and the corresponding vertical pipe 303 (i.e. Fig.10 The left side of the middle stopper 703), at this time, the side plate 601 and the slide block 902 are hidden in the inclined frame 4 and are not affected.

[0063] When in use, the vertical tube 303 is driven to revolve and rotate and the workpiece is driven to move synchronously through structures such as the toothed disk 502 and the gear 503. The workpiece is driven to transfer between two corresponding inclined frames 4 of adjacent vertical tubes 303 through structures such as the gear 503, the first pull rope 903 and the second pull rope 904. The smooth transfer of the workpiece between the two inclined frames 4 is achieved through the cooperation of structures such as the slider 902 and the side plate 601. The working process and effect of this part are the same as those in Example 2 and will not be repeated here. The difference is that: when the inclined frame 4 rotates relative to the vertical tube 303, the slider 902 and the side plate 601 are driven to move synchronously. When the inclined frame 4 rotates downward again based on the horizontal state, the slider 902 and the side plate 601 gradually slide out relative to the inclined frame 4, and the workpiece is stopped by the block 703 when moving along the inclined downward inclined frame 4; when the slider 902 drives the side plate 601 to move completely out of the inclined frame 4, the side plate 601 automatically opens based on the slider 902 to correspond to the end of the other inclined frame 4, and pulls the third pull rope 702 to make the round rod 701 and the block 703 rotate counterclockwise. When the block 703 rotates counterclockwise, it first pushes the workpiece to move in the opposite direction for a distance. When the block 703 is completely hidden in the groove 402, the workpiece can slide down smoothly along the inclined frame 4 and be transferred to the other inclined frame 4 through the slider 902.

[0064] In the second embodiment, the two side plates 601 are opened to correspond to the other inclined frame 4 to prevent the workpiece from being stuck at the junction of the slider 902 and the other inclined frame 4. However, when the inclined frame 4 is rotated downward, the workpiece slides down along the inclined frame 4 at a fast speed, so that the workpiece slides down and gets stuck before the side plate 601 corresponds to the other inclined frame 4, which has certain limitations in use.

[0065] Compared with the second embodiment, through the cooperation of structures such as the side plate 601, the groove 402, the stopper 703 and the third pull rope 702, when the side plate 601 is opened relative to the slider 902, on the one hand, it corresponds to the end of the other inclined frame 4, and on the other hand, it can also drive the stopper 703 to rotate and hide in the groove 402. When rotating, the stopper 703 first pushes the workpiece to move in the opposite direction for a distance, and then releases the limit on the workpiece so that the workpiece can slide down, ensuring the successful correspondence between the side plate 601 and the end of the other inclined frame 4, so that the workpiece can stably slide to the other inclined frame 4 through the slider 902; the overall solution utilizes the opening of the side plate 601 relative to the slider 902, and will not affect the movement of the slider 902 relative to the inclined frame 4, meeting more requirements in actual use.
