Description

Technical Field

[0001] The invention relates to the technical field of NdFeB magnet processing, in particular to a device for drying and processing the surface of a sintered NdFeB magnet. Background Art

[0002] During the processing of NdFeB magnets, it is necessary to clean the impurities and oil stains on the surface of the NdFeB magnets. After the surface is cleaned, there will be water stains remaining on the surface of the NdFeB magnets, so the surface of the NdFeB magnets needs to be dried.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention provides a surface drying treatment device for sintered NdFeB magnets, wherein the NdFeB magnets are placed in a drying box, the resistance heating rod group is working, and the reciprocating flip assembly drives the drying box to flip and swing slightly along the posture cycle of "high on the left and low on the right - low on the left and high on the right". When the drying box is in an inclined posture of high on the left and low on the right or low on the left and high on the right, the oscillation assembly works, thereby driving the drying box to oscillate. This allows the NdFeB magnets attached to the high end of the drying box to fall off quickly. The reciprocating flip assembly drives the NdFeB magnets located in the drying box to flip and swing slightly along the posture cycle of "high on the left and low on the right - low on the left and high on the right" to improve the tiling efficiency of the NdFeB magnets in the drying box, and the oscillation assembly works periodically to oscillate the drying box, thereby preventing the NdFeB magnets from adhering to the inner wall of the drying box.

[0027] (2) The present invention provides a sintered NdFeB magnet surface drying treatment device, in which the side-rotating motor periodically rotates forward and reverse, thereby driving the transverse screw installed at the output end of the side-rotating motor to periodically rotate forward and reverse on the flip seat. When the transverse screw rotates, it drives the two transverse screw blocks sleeved thereon to move synchronously, and the flip rod connected to the transverse screw block drives the lifting block to slide in the vertical slot, and the lifting block drives the limit horizontal frame connected to it to slide along the vertical slot, and the two flip rods on each transverse screw drive the lifting block to move in opposite directions, so that the limit slider connected to the limit horizontal frame and the drying box connected to the limit slider can be turned and swung slightly left and right. Then, the NdFeB magnet can be quickly spread flat in the drying box. Synchronously, the side rotating shaft connected to the traverse screw by a pair of meshing helical gears rotates on the side mounting frame, and the side rotating shaft drives the eccentric disk to rotate. When the large radius end of the eccentric disk abuts against the side end of the oscillation seat, the reset spring is compressed, and the traverse block moves in the traverse groove in the compression direction of the reset spring, thereby driving the flip seat connected to the traverse block to move in the compression direction of the reset spring at the top of the oscillation seat. At this time, the distance between the oscillation block integrally connected to the flip seat and the oscillation seat is the largest. When the drying box is in the maximum tilt state of "high on the left and low on the right" or "low on the left and high on the right", the large radius end of the eccentric disk releases the abutment against the side end of the oscillation seat. After losing the limit of the large radius end of the eccentric disk, the reset spring quickly resets and stretches, thereby driving the traverse block to quickly move in the traverse groove in the extension direction of the reset spring, thereby driving the flip seat connected to the traverse block to move in the extension direction of the reset spring at the top of the oscillation seat. The oscillation block quickly hits the side end of the oscillation seat. Then the oscillating motion of the turning seat connected to the oscillating block is realized, so that the NdFeB magnet attached to the high end of the drying box can be quickly dropped off.

[0038] Example

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] like Figures 1 to 7 As shown, a sintered NdFeB magnet surface drying treatment device provided in this embodiment includes: a drying shell 10;

[0041] A reciprocating flip assembly 11, the reciprocating flip assembly 11 is located in the drying shell 10, a drying box 12 is installed on the reciprocating flip assembly 11, the drying box 12 is used to place the NdFeB magnet, the reciprocating flip assembly 11 includes a flip seat 14 and a resistance heating rod group 15 installed on the top of the flip seat 14, and the drying box 12 is located above the resistance heating rod group 15;

[0042] The oscillating assembly 13 is installed at the bottom of the drying shell 11 , and the oscillating assembly 13 is transmission-connected to the bottom end of the reciprocating turning assembly 11 .

[0043] The working principle and beneficial effects of the above technical solution are:

[0044] The present invention provides a surface drying treatment device for sintered NdFeB magnets. The NdFeB magnets are placed in a drying box 12, the resistance heating rod group 15 is working, and the reciprocating flip assembly 11 drives the drying box 12 to flip and swing in a small amplitude along the posture cycle of "high on the left and low on the right-low on the left and high on the right". When the drying box 12 is in an inclined posture of high on the left and low on the right or low on the left and high on the right, the oscillation assembly 13 works, thereby driving the drying box 12 to oscillate. In this way, the NdFeB magnets attached to the high end of the drying box 12 can fall off quickly. The present invention discloses a surface drying treatment device for sintered NdFeB magnets, wherein a reciprocating flipping component 11 drives the NdFeB magnets in a drying box 12 to perform a small flipping and swinging along a posture cycle of "high on the left and low on the right - low on the left and high on the right" to improve the laying efficiency of the NdFeB magnets in the drying box 12, and an oscillating component 13 works periodically to oscillate the drying box 12, thereby preventing the NdFeB magnets from adhering to the inner wall of the drying box 12.

[0045] In one embodiment, the box cover 16 is located at the top of the drying box 12 , the box cover 16 is connected to the drying box 12 via a side buckle, the handle is installed on the box cover 16 , and drying holes are evenly opened on the box cover 16 and the drying box 12 .

[0046] The working principle and beneficial effects of the above technical solution are:

[0047] The box cover 16 is opened, and the NdFeB magnets are placed in the drying box 12. The box cover 16 is locked on the drying box 12 by the side buckle, so that the NdFeB magnets will not leak out when the drying box 12 is slightly turned and swung left and right. If the drying box 12 is slightly turned and swung left and right, the NdFeB magnets can be quickly spread in the drying box 12.

[0048] In one embodiment, the reciprocating turning assembly 11 further includes:

[0049] Transverse screw rods 17, two transverse screw rods 17 are installed in parallel on the turning seat 14, and two transverse screw blocks 18 are sleeved on each transverse screw rod 17. The transverse screw rods 17 are connected to the oscillating assembly 13 through a pair of meshing bevel gears 25;

[0050] Vertical moving frames 19, four vertical moving frames 19 are arranged in groups of two, each group of vertical moving frames 19 is arranged near each transverse moving screw 17, each vertical moving frame 19 is provided with a vertical moving slot 20, the vertical moving frame 19 is located between two transverse moving screws 17, and the drying box 12 is located between the two groups of vertical moving frames 19;

[0051] The limiting sliders 21 are installed in pairs at the side ends of the drying box 12. Each limiting slider 21 is configured with a limiting horizontal frame 22. A flip rod 23 is rotatably installed on each transverse moving screw block 18. A lifting block 24 is rotatably installed on the end of the flip rod 23 away from the transverse moving screw block 18. The lifting block 24 is slidably installed in the vertical moving groove 20 and is fixedly connected to the limiting horizontal frame 22.

[0052] The working principle and beneficial effects of the above technical solution are:

[0053] The transverse screw 17 rotates, thereby driving the two transverse screw blocks 18 sleeved thereon to move synchronously, and the flip rod 23 connected to the transverse screw block 18 drives the lifting block 24 to slide in the vertical slot 20, and the lifting block 24 drives the limit horizontal frame 22 connected thereto to slide along the vertical slot 20, and the two flip rods 23 on each transverse screw 17 drive the lifting block 24 to move in opposite directions, so that the limit slider 21 connected to the limit horizontal frame 22 and the drying box 12 connected to the limit slider 21 can be turned and swung slightly left and right. Then, the NdFeB magnets can be quickly laid flat in the drying box 12.

[0054] In one embodiment, the end of the transverse screw 17 away from the bevel gear 25 is transmission-connected to a side rotation motor 26 , and the side rotation motor 26 is fixedly mounted on the flip seat 14 .

[0055] The working principle of the above technical solution is:

[0056] The side rotating motor 26 rotates forward and reverse periodically, thereby driving the transverse screw 17 installed at the output end of the side rotating motor 26 to rotate forward and reverse periodically on the turning seat 14, thereby realizing the drying box 12 to turn and swing slightly left and right.

[0057] In one embodiment, the oscillating assembly 13 comprises:

[0058] The oscillating seat 27 is fixedly mounted on the bottom of the drying shell 11, and the turning seat 14 is slidably mounted on the top of the oscillating seat 27. The bottom of the turning seat 14 is integrally formed with an oscillating block 28 near the bevel gear 25;

[0059] A transverse groove 29 is provided at the top of the oscillation seat 27, a transverse block 30 is slidably installed in the transverse groove 29, and the transverse block 30 is fixedly connected to the bottom end of the flip seat 14;

[0060] A return spring 31, which is located in the transverse groove 29 and connected between the inner wall of the transverse groove 39 and the transverse block 30;

[0061] A side mounting frame, the side mounting frame is connected to the oscillating block 28, and the side rotating shaft 32 is rotatably mounted on the side mounting frame, wherein one of the bevel gears 25 is mounted on the transverse screw 17, and wherein another bevel gear 25 is mounted on the side rotating shaft 32;

[0062] The eccentric disk 33 is mounted on the side rotating shaft 32 , and the eccentric disk 33 is disposed against the side end of the oscillation seat 27 .

[0063] The working principle and beneficial effects of the above technical solution are:

[0064] The side rotating motor 26 rotates forward and reverse periodically, thereby driving the transverse screw 17 installed at the output end of the side rotating motor 26 to rotate forward and reverse periodically on the flip seat 14, thereby realizing the small-amplitude flipping and swinging of the drying box 12 to the left and right. At the same time, the side rotating shaft 32 connected to the transverse screw 17 through a pair of meshing bevel gears 25 rotates on the side mounting frame, and the side rotating shaft 32 drives the eccentric disk 33 to rotate. When the large radius end of the eccentric disk 33 abuts against the side end of the oscillation seat 27, the reset spring 31 is compressed, and the transverse block 30 moves in the transverse groove 29 in the compression direction of the reset spring 31, thereby driving the flip seat 14 connected to the transverse block 30 to rotate on the oscillation seat 2 7 moves in the compression direction of the return spring 31. At this time, the distance between the oscillation block 28 and the oscillation seat 27, which are integrally connected to the flip seat 14, is the largest. When the drying box 12 is in the maximum tilt state of "high on the left and low on the right" or "low on the left and high on the right", the large radius end of the eccentric disk 33 releases the abutment against the side end of the oscillation seat 27. After the large radius end of the eccentric disk 33 is lost, the return spring 31 quickly returns and stretches, thereby driving the traverse block 30 to quickly move in the traverse groove 29 in the extension direction of the return spring 31, thereby driving the flip seat 14 connected to the traverse block 30 to move in the extension direction of the return spring 31 at the top of the oscillation seat 27. The oscillation block 28 quickly hits the side end of the oscillation seat 27. Thus, the oscillation action of the flip seat 14 connected to the oscillation block 28 is realized, so that the NdFeB magnet attached to the high end of the drying box 12 can be quickly dropped off.

[0065] In one embodiment, a plurality of thickened sheets 34 are detachably mounted on the side ends of the oscillation seat 27 , and the eccentric disk 33 is disposed against the thickened sheets 34 .

[0066] The working principle and beneficial effects of the above technical solution are:

[0067] The side ends of the oscillation seat 27 are detachably mounted with a plurality of thickening sheets 34. By increasing or decreasing the number of thickening sheets 34, the distance between the oscillation block 28 and the oscillation seat 27 can be changed. When the humidity of the NdFeB magnet is high, the number of thickening sheets 34 can be increased, and the distance between the oscillation block 28 and the oscillation seat 27 becomes larger. In this way, after the large radius end of the eccentric disk 33 releases the support against the side end of the oscillation seat 27, the force with which the oscillation block 28 hits the side end of the oscillation seat 27 also increases, thereby increasing the oscillation action of the drying box 12, so that the NdFeB magnet attached to the high end of the drying box 12 can fall off quickly. When the humidity of the NdFeB magnet is low, the number of thickening sheets 34 can be reduced, and the distance between the oscillation block 28 and the oscillation seat 27 becomes smaller. In this way, after the large radius end of the eccentric disk 33 releases the resistance against the side end of the oscillation seat 27, the force with which the oscillation block 28 hits the side end of the oscillation seat 27 also becomes smaller, thereby reducing the oscillation action of the drying box 12.

[0068] In one embodiment, a bottom opening 35 is formed at the bottom end of the drying shell 10 to facilitate the eccentric disk 33 and the thickened sheet 34 to protrude.

[0069] The beneficial effects of the above technical solution are:

[0070] The bottom opening 35 is provided to facilitate the increase or decrease of the number of thickening sheets 34 according to the humidity of the NdFeB magnet, and to facilitate the observation of the movement of the eccentric disk 33.

[0071] In one embodiment, a side opening is formed at a side end of the drying shell 10 to facilitate the tipping seat 14 to protrude from the end close to the rotating motor 26 .

[0072] The beneficial effects of the above technical solution are:

[0073] The side opening does not cause motion interference when the turning seat 14 moves toward the inner wall of the drying shell 10 near the end of the rotating motor 26. The rotating motor 26 protrudes out of the drying shell 10 and is easy to dissipate the heat on its surface, which is convenient for cooling.

[0074] In one embodiment, a sliding chamber 36 is formed on the inner wall of the transverse groove 29 at a position away from the return spring 31 , and a guide slider 37 is slidably connected in the sliding chamber 36 and fixedly connected to the transverse block 30 .

[0075] The beneficial effects of the above technical solution are:

[0076] The arrangement of the guide slide block 37 and the sliding chamber 36 facilitates the stability of the movement of the flip seat 14 .

[0077] In one embodiment, a top opening cover is installed on the top of the drying housing 10 .

[0078] The beneficial effects of the above technical solution are:

[0079] The upper opening cover is provided to facilitate the opening and closing of the drying shell 10 .

[0080] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
