[0033] Example 1

[0034] A surface cleaning device for rust removal of NdFeB magnet material, comprising a support frame 1, a cylinder 2, a baffle 21, a cleaning frame 3, a shielding frame 31, a feed hopper 32, a discharge hopper 33, a spline shaft 34, a driving mechanism 4 and a sliding mechanism 5, see Figure 1-Figure 7 As shown, a cylinder 2 is fixedly connected to the inner side of the support frame 1 along the circumferential direction, a feed hopper 32 is connected to the upper front side of the cylinder 2, a baffle 21 is installed on the lower inner side of the cylinder 2 along the circumferential direction by welding, a cleaning rack 3 is arranged in the cylinder 2, when the cleaning rack 3 rotates, the cleaning rack 3 can clean the surface of the NdFeB magnet material, a spline shaft 34 is fixedly connected to the middle of the bottom of the cleaning rack 3, the spline shaft 34 passes through the middle of the baffle 21, a discharge hopper 33 is connected to the lower right side of the cylinder 2, a shielding frame 31 is embedded in the lower right side of the cylinder 2 and is slidably connected, the lower part of the shielding frame 31 is grid-shaped, the shielding frame 31 can close the inside of the discharge hopper 33, a sliding mechanism 5 is arranged between the baffle 21 and the cylinder 2, when the sliding mechanism 5 moves, the sliding mechanism 5 can drive the cleaning rack 3 to move, a driving mechanism 4 is arranged between the baffle 21 and the cylinder 2, when the driving mechanism 4 operates, the driving mechanism 4 can drive the sliding mechanism 5 to move.

[0035] The driving mechanism 4 includes a mounting frame 41, a servo motor 42 and a threaded cylinder 43, see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a threaded barrel 43 is rotatably connected in the middle of the bottom of the barrel 2. The lowermost side of the thread of the threaded barrel 43 is an annular groove. A spline groove is opened on the inner side of the threaded barrel 43. The spline shaft 34 is located in the threaded barrel 43. When the threaded barrel 43 rotates, the threaded barrel 43 can drive the sliding mechanism 5 to operate. A mounting frame 41 is installed on the outer bottom of the barrel 2 by welding. A servo motor 42 is fixed to the mounting frame 41. The output shaft end of the servo motor 42 is connected to the bottom end of the threaded barrel 43.

[0036] The sliding mechanism 5 includes a sliding frame 51, a first spring 52 and a sliding plate 53, see Figure 2 , Figure 6 and Figure 7 As shown, a sliding frame 51 is slidably connected to the baffle 21, and the sliding frame 51 is in contact with the bottom of the cleaning frame 3. When the sliding frame 51 moves, the sliding frame 51 can drive the cleaning frame 3 to move. A pulley is arranged on the top of the sliding frame 51, and a sliding plate 53 is slidably connected to the inner side of the cylinder 2 through a sliding groove. The top of the sliding plate 53 is connected to the bottom of the sliding frame 51 by welding. The middle part of the sliding plate 53 is threadedly mounted on the threaded cylinder 43. A first spring 52 is connected between the top of the sliding plate 53 and the bottom of the baffle 21, and the first spring 52 is mounted on the threaded cylinder 43.

[0037] First, pour a proper amount of NdFeB magnet material into the cylinder 2 through the feed hopper 32, and the NdFeB magnet material contacts the cleaning rack 3. Then pour a proper amount of water into the cylinder 2 through the feed hopper 32, and the water contacts the cleaning rack 3 and the NdFeB magnet material. Start the driving mechanism 4, and the driving mechanism 4 drives the sliding mechanism 5 to move upward. The sliding mechanism 5 moves upward and drives the cleaning rack 3 to move upward. The cleaning rack 3 moves upward and drives the NdFeB magnet material to move upward. The NdFeB magnet material moves upward and is cleaned by water. When the sliding mechanism 5 moves upward to the maximum stroke, the driving mechanism 4 is controlled to drive the sliding mechanism 5 to move downward and reset. The sliding mechanism 5 resets without limiting the cleaning frame 3. Due to the effect of gravity, the cleaning frame 3 moves downward and resets, and this is repeated repeatedly to continuously clean the surface of the NdFeB magnet material. The washing rack 3 drives the NdFeB magnet material to move up and down to clean the surface with water. When the surface of the NdFeB magnet material is cleaned, the collection container for collecting water is placed under the discharge hopper 33, and the shielding rack 31 is pulled upward to make the grid-shaped part correspond to the discharge hopper 33. The water in the cylinder 2 flows into the discharge hopper 33 through the shielding rack 31, and the water in the discharge hopper 33 flows into the collection container. When all the water is discharged, the collection container is picked up, and a new collection container is placed under the discharge hopper 33, and the shielding rack 3 is pulled upward to make the grid-shaped part correspond to the discharge hopper 33. 1 moves upward without sealing the inside of the feed hopper 32. Since the rotation of the cleaning rack 3 drives the NdFeB magnet material to rotate, the rotation of the cleaning rack 3 throws the NdFeB magnet material into the discharge hopper 33 through centrifugal force. The NdFeB magnet material in the discharge hopper 33 is discharged into the collection container. When all the NdFeB magnet material is discharged, the shielding rack 31 is pulled downward to reset, and the driving mechanism 4 is closed. The driving mechanism 4 stops driving the sliding mechanism 5 to move, and the driving mechanism 4 also stops driving the spline shaft 34 to rotate, and the cleaning rack 3 also stops rotating.

[0038] When an appropriate amount of water and NdFeB magnet material are poured into the barrel 2, the servo motor 42 is started to rotate forward to drive the threaded barrel 43 to rotate forward. The threaded barrel 43 rotates forward through the thread to drive the sliding mechanism 5 to move upward. The sliding mechanism 5 moves upward to drive the cleaning rack 3 to move upward. The cleaning rack 3 also drives the NdFeB magnet material to move upward to be cleaned by water. At the same time, the threaded barrel 43 rotates forward and drives the spline shaft 34 to rotate forward through the spline groove. The spline shaft 34 rotates forward to drive the cleaning rack 3 to rotate forward. The cleaning rack 3 rotates forward to clean the surface of the NdFeB magnet material through water. When the sliding mechanism 5 moves forward, the spline shaft 34 rotates forward. When it moves up to the maximum stroke, the servo motor 42 is started to drive the threaded barrel 43 to reverse. The threaded barrel 43 reverses and drives the sliding mechanism 5 to move downward and reset through the thread. The sliding mechanism 5 resets without limiting the cleaning rack 3. The cleaning rack 3 moves downward and resets, so that the NdFeB magnet material moves downward. At the same time, the reversal of the threaded barrel 43 also drives the spline shaft 34 to reverse. The reversal of the spline shaft 34 drives the cleaning rack 3 to reverse and continue to clean the surface of the NdFeB magnet material. This is repeated, and the cleaning rack 3 can be continuously moved up and down and rotated to clean the surface of the NdFeB magnet material. When the surface of the NdFeB magnet material is cleaned, start the servo motor 42 to drive the threaded barrel 43 to reverse continuously. Since the lower side of the thread of the threaded barrel 43 is an annular groove, the continued reversal of the threaded barrel 43 will not drive the sliding mechanism 5 to continue to move downward. The reversed threaded barrel 43 continues to drive the cleaning rack 3 to reverse through the spline shaft 34 to throw the NdFeB magnet material into the discharge hopper 33. Turn off the servo motor 42, and the threaded barrel 43 stops driving the cleaning rack 3 to rotate through the spline shaft 34.

[0039] Initially, the first spring 52 is in a stretched state, and the sliding plate 53 contacts the annular groove of the threaded barrel 43. When the servo motor 42 starts to drive the threaded barrel 43 to rotate forward, the threaded barrel 43 rotates forward so that the opening of the thread corresponds to the inner end of the sliding plate 53. Due to the action of the first spring 52, the sliding plate 53 moves upward by a certain distance and contacts the thread of the threaded barrel 43. The forward rotation of the threaded barrel 43 drives the sliding plate 53 to move upward through the thread, and the first spring 52 slowly resets from the stretched state. The sliding plate 53 moves upward and drives the sliding frame 51 to move upward. The sliding frame 51 moves upward and drives the cleaning frame 3 to move upward through the pulley. The cleaning frame 3 moves upward and drives the NdFeB magnet material to move upward, which makes the water clean the surface of the NdFeB magnet material. Then, when the cleaning frame 3 rotates, the sliding frame 51 is provided with a pulley to reduce friction and avoid affecting the rotation of the cleaning frame 3. When the sliding plate 53 When the thread barrel 43 moves upward to the maximum stroke, the servo motor 42 is started to drive the thread barrel 43 to reverse, and the thread barrel 43 reverses and drives the sliding plate 53 to move downward and reset through the thread. The sliding plate 53 resets so that the first spring 52 is stretched again, and the sliding plate 53 resets and drives the sliding frame 51 to move downward and reset. The sliding frame 51 resets without limiting the cleaning frame 3. Due to the effect of gravity, the cleaning frame 3 moves downward and resets to continue to contact the sliding plate 53. This is repeated, and the NdFeB magnet material can be continuously driven up and down to be cleaned by water. When the surface of the NdFeB magnet material is cleaned, the servo motor 42 is started to drive the thread barrel 43 to reverse all the time. Since the lower side of the thread of the thread barrel 43 is an annular groove, the thread barrel 43 continues to reverse and will not drive the sliding plate 53 to continue to move downward. The thread barrel 43 reverses and continues to drive the cleaning frame 3 to reverse through the spline shaft 34 to throw the NdFeB magnet material into the discharge hopper 33. When all the NdFeB magnet materials are thrown out, the servo motor 42 is turned off and stops driving the thread barrel 43 to rotate.

[0040] Example 2

[0041] On the basis of embodiment 1, an auxiliary cleaning mechanism 6 is also included. The auxiliary cleaning mechanism 6 includes a U-shaped plate 61, a vertical shaft 62, a rotating disk 63 and a brush roller 64. Figure 1 , Figure 2 and Figure 8 As shown, a rotating disk 63 is rotatably connected to the upper inner part of the cylinder 2 along the circumferential direction, and a brush roller 64 is symmetrically fixed to the bottom of the rotating disk 63. When the brush roller 64 rotates, the brush roller 64 can stir the water. A U-shaped plate 61 is installed on the lower left side of the outer side of the cylinder 2 by welding. A vertical shaft 62 is rotatably connected to the U-shaped plate 61. The lower part of the vertical shaft 62 and the output shaft of the servo motor 42 are driven by a synchronous belt, and the upper part of the vertical shaft 62 and the upper part of the rotating disk 63 are driven by gears.

[0042] The liquid adding mechanism 7 includes an annular compression cylinder 71, a magnetic plate 72, a second spring 73, a piston plate 74, a one-way liquid inlet pipe 75 and a one-way liquid outlet pipe 76. Figure 2 , Fig. 9 and Fig.10 As shown, an annular compression cylinder 71 is fixedly connected to the bottom of the cylinder 2, and a piston plate 74 is slidably connected to the annular compression cylinder 71. A magnetic attraction plate 72 is fixedly connected to the upper part of the piston plate 74 along the circumferential direction. The magnetic attraction plate 72 is in magnetic contact with the sliding plate 53. A second spring 73 is connected between the bottom of the magnetic attraction plate 72 and the outer top of the annular compression cylinder 71. The second spring 73 is sleeved on the piston plate 74. A one-way liquid inlet pipe 75 is connected to the rear side of the bottom of the annular compression cylinder 71. The bottom end of the one-way liquid inlet pipe 75 passes through the bottom of the cylinder 2. A one-way liquid outlet pipe 76 is connected to the lower front side of the annular compression cylinder 71. The tail end of the one-way liquid outlet pipe 76 passes through the upper front side of the cylinder 2. When the cleaning agent is discharged into the one-way liquid outlet pipe 76, the one-way liquid outlet pipe 76 can discharge the cleaning agent into the cylinder 2.

[0043] When the servo motor 42 starts to rotate forward, the servo motor 42 rotates forward through the synchronous belt drive to drive the vertical shaft 62 to rotate forward, the vertical shaft 62 rotates forward through the gear drive to drive the rotating disk 63 to rotate backward, and the rotating disk 63 rotates backward to drive the two brush rollers 64 to rotate backward. Since the reverse rotation of the two brush rollers 64 is inconsistent with the rotation direction of the forward rotation of the cleaning rack 3, the two brush rollers 64 rotate backward to stir the water, which makes the NdFeB magnet material in the water move more randomly, and the water also cleans the surface of the NdFeB magnet material better, and the cleaning is cleaner. When the servo motor 42 starts to reverse, the servo motor 42 drives the vertical shaft 62 to rotate backward through the synchronous belt drive, and the vertical shaft 62 rotates backward through the gear drive to drive the rotating disk 63 to rotate forward, and the rotating disk 63 rotates forward to drive the two brush rollers 64 to rotate forward, and the two brush rollers 64 rotate forward to stir the water and the NdFeB magnet material. When the surface of the NdFeB magnet material is cleaned, turn off the servo motor 42, and the rotating disk 63 stops driving the two brush rollers 64 to rotate. In this way, the surface of the NdFeB magnet material can be cleaned more cleanly and the cleaning effect is better.

[0044] When the cylinder 2 is filled with an appropriate amount of NdFeB magnet material and water, the one-way liquid inlet pipe 75 is connected to a container containing a disposable cleaning agent, and then when the servo motor 42 is started to drive the threaded cylinder 43 to rotate forward, the sliding plate 53 moves upward and drives the magnetic attraction plate 72 to move upward through the magnetic force, the second spring 73 is stretched, and the magnetic attraction plate 72 moves upward to drive the piston plate 74 to move upward, and the piston plate 74 moves upward to draw all the cleaning agent in the container into the annular compression cylinder 71 through the one-way liquid inlet pipe 75. When the second spring 73 is stretched to the maximum stroke, the second spring 73 limits the piston plate 74, and the piston plate 74 stops moving upward, and the piston plate 74 also stops the magnetic attraction plate 72 from moving upward. The sliding plate 53 moves upwards and disengages from the magnetic plate 72. Due to the action of the second spring 73, the magnetic plate 72 moves downwards and resets, driving the piston plate 74 to move downwards and resets. The piston plate 74 resets and discharges the cleaning agent in the annular compression cylinder 71 into the one-way liquid outlet pipe 76. The cleaning agent in the one-way liquid outlet pipe 76 is discharged into the water in the cylinder 2. The water and the cleaning agent are fused together, which makes the cleaning rack 3 clean the NdFeB magnet material more clean. When the subsequent sliding plate 53 resets and contacts the magnetic plate 72 again, the sliding plate 53 moves upwards and continues to drive the magnetic plate 72 to move upwards. However, since there is no cleaning agent in the container, the piston plate 74 moves upwards and starts to draw in air. When the surface of the NdFeB magnet material is cleaned, the servo motor 42 is turned off, the sliding plate 53 stops driving the magnetic plate 72 to move upwards, and the piston plate 74 also stops moving. In this way, there is no need for people to manually pour the cleaning agent into the water, which is convenient and quick.

[0045] Example 3

[0046] On the basis of the embodiment 1 and the embodiment 2, an air drying mechanism 8 is also included. The air drying mechanism 8 includes a dust cover 81 and a fan 82. Figure 2 and Fig.11 As shown, a dust cover 81 is installed on the upper inner part of the cylinder 2 by welding. The middle part of the dust cover 81 is rotatably mounted on the upper part of the rotating disk 63. A fan 82 is fixedly mounted on the upper part of the rotating disk 63 along the circumferential direction. When the fan 82 rotates, the fan 82 can blow out wind to dry the NdFeB magnet material.

[0047] The device also includes an adsorption mechanism 9, which includes a fixed magnetic ring 91, a sliding magnetic ring 92, a guide column 93 and a third spring 94. Figure 1 , Figure 2 and Fig.12As shown, a fixed magnetic ring 91 is fixedly connected to the upper outer part of the cylinder 2 along the circumferential direction, four guide pillars 93 are fixedly connected to the bottom of the fixed magnetic ring 91 at uniform intervals along the circumferential direction, and a sliding magnetic ring 92 is slidably mounted between the four guide pillars 93. When the shielding frame 31 moves upward and contacts the sliding magnetic ring 92, the sliding magnetic ring 92 can absorb and fix the shielding frame 31. Four third springs 94 are evenly spaced and connected between the top of the sliding magnetic ring 92 and the bottom of the fixed magnetic ring 91, and the four third springs 94 are respectively mounted on the four guide pillars 93.

[0048] Also includes a cover plate 10, see Figure 1 and Figure 2 As shown, a cover plate 10 is clamped on the top of the feed hopper 32 .

[0049] When the rotating disk 63 rotates, the rotating disk 63 also drives the fan 82 to rotate, and the fan 82 rotates to blow wind into the cylinder 2, and the wind dries the NdFeB magnet material, and also removes the water on the NdFeB magnet material. At the same time, the dust cover 81 can prevent foreign debris from falling into the cylinder 2 and damaging the fan 82. When the rotating disk 63 stops rotating, the rotating disk 63 stops driving the fan 82 to rotate. In this way, the NdFeB magnet material can be dried, which is more convenient for subsequent processing.

[0050] When the water needs to be discharged, the shielding frame 31 is pulled upward to contact the sliding magnetic ring 92. The sliding magnetic ring 92 attracts and fixes the shielding frame 31 through magnetic force, and the shielding frame 31 is released. At this time, the water in the cylinder 2 is discharged into the discharge hopper 33 through the shielding frame 31, and the water in the discharge hopper 33 is discharged into the collection container. When all the water is discharged, the shielding frame 31 continues to be pulled upward to drive the sliding magnetic ring 92 to move upward. The four third springs 94 are compressed. When the sliding magnetic ring 92 moves upward and contacts the fixed magnetic ring 91, the fixed magnetic ring 91 attracts and fixes the sliding magnetic ring 92 through magnetic force, and the shielding frame 31 is released. At this time, the shielding frame 31 does not close the discharge hopper 33, and the neodymium iron boron magnet material is thrown into the discharge hopper 33 and falls into the collection container. After all the NdFeB magnet materials are thrown out and collected, the sliding magnetic ring 92 is pulled downward to disengage from the fixed magnetic ring 91. Due to the action of the four third springs 94, the sliding magnetic ring 92 moves downward to reset and drives the shielding frame 31 to move downward a certain distance. Then the shielding frame 31 is pulled downward to reset, and the shielding frame 31 is reset and disengaged from the sliding magnetic ring 92. In this way, there is no need for people to pull the shielding frame 31 to limit the position all the time, which is more convenient.

[0051] When it is necessary to pour NdFeB magnet material and water into the cylinder 2 through the feed hopper 32, the cover plate 10 is removed from the feed hopper 32, and then an appropriate amount of NdFeB magnet material and water are poured into the cylinder 2 through the feed hopper 32, and then the cover plate 10 is snapped back onto the feed hopper 32. In this way, foreign debris can be prevented from falling into the cylinder 2 through the feed hopper 32.
