[0024] A laser cutting device for NdFeB processing provided by the present invention is now described.

[0025] like Figures 1 to 3 As shown, one embodiment of the present invention provides a laser cutting device for NdFeB processing, comprising a body 1, on which a three-dimensional moving module 11 and a cutting gun 12 are arranged, and the three-dimensional moving module 11 is used to drive the cutting gun 12 to move along the xyz axis; a cutting table 2 is arranged in the body 1, and a clamping mechanism 3 for fixing the NdFeB at the cutting station is arranged on the cutting table 2; a silo 4 for stacking NdFeB is arranged on one side of the cutting table 2, and a feeding mechanism 5 for feeding the NdFeB in the silo 4 one by one to the clamping mechanism 3 is arranged on the cutting table 2; a feeding port 21 is opened on the cutting table 2 at a position directly below the NdFeB cutting station, and a screening mechanism 6 is arranged in the body 1 below the feeding port 21 (refer to Figure 5 ), the screening mechanism 6 is used to separate the cut NdFeB, the cut material blocks and the slag produced by cutting.

[0026] Compared with the prior art, the laser cutting device for NdFeB processing provided in the present embodiment first stacks a plurality of NdFeBs into a silo 4. When the NdFeBs need to be cut, a single NdFeB is delivered to the clamping mechanism 3 through the feeding mechanism 5. After the clamping mechanism 3 clamps and fixes the NdFeBs, the three-dimensional moving module 11 drives the cutting gun 12 to move and cut. After the NdFeB cutting is completed, the clamping mechanism 3 releases the clamping of the NdFeB and causes it to fall into the unloading port 21. The screening mechanism 6 separates the cut NdFeBs, the cut material blocks and the slag produced by the cutting for subsequent processing, thereby improving the loading and unloading efficiency during the overall laser cutting process.

[0027] like Figure 3 to Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The clamping mechanism 3 includes a positioning frame 31, a first slide rail 32, a movable frame 33, a clamping plate 34, an adjusting cylinder 35 and an adjusting positioning member 36; the positioning frame 31 is fixed on the cutting table 2, the first slide rail 32 is fixed on the cutting table 2 and is perpendicular to the positioning frame 31, and the movable frame 33 is slidably arranged on the first slide rail 32 and is arranged opposite to the positioning frame 31; there are two clamping plates 34 and they are arranged opposite to each other, one of which is slidably arranged on the positioning frame 31, and the other clamping plate 34 is fixed on the movable frame 33; the adjusting cylinder 35 is arranged on the positioning frame 31 and is used to drive the corresponding clamping plate 34 to move, and the adjusting positioning member 36 is arranged on the cutting table 2 and is used to drive the movable frame 33 to move.

[0028] Before cutting NdFeB, the position of the moving frame 33 is adjusted by adjusting the positioning member 36 according to the size of the NdFeB, so that the distance between the moving frame 33 and the positioning frame 31 matches the size of the NdFeB.

[0029] After the feeding mechanism 5 delivers the NdFeB to between the two clamping plates 34, the regulating cylinder 35 is started to make the clamping plates 34 on the moving frame 33 clamp the NdFeB between the clamping plates 34 on the positioning frame 31, which can be suitable for NdFeB of different sizes and improves the clamping and fixing efficiency of the NdFeB.

[0030] like Figure 3 to Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The adjustment positioning member 36 includes a bracket 361, a screw 362 and a locking member 363. The bracket 361 is fixed on the cutting table 2. The screw 362 is threadedly connected to the bracket 361 and is parallel to the first slide rail 32. One end of the screw 362 is rotatably connected to the movable frame 33, and a hand wheel is provided at the other end of the screw 362. The locking member 363 is provided on the bracket 361 and is used to fix the screw 362.

[0031] Specifically, in this embodiment, the locking member 363 is an axis fixing clamp and a bolt. The axis fixing clamp is set on the bracket 361, the screw 362 passes through the axis fixing clamp, and the bolt is threadedly connected to the axis fixing clamp. Tightening or loosening the bolt can achieve the clamping or releasing of the screw 362 by the axis fixing clamp.

[0032] When the distance between the moving frame 33 and the positioning frame 31 needs to be adjusted, the locking member 363 is first released to fix the screw rod 362, and then the hand wheel is turned to rotate the screw rod 362, so that the moving frame 33 can be driven to move on the first slide rail 32, thereby improving the efficiency of position adjustment of the moving frame 33. After the movement is completed, the screw rod 362 is fixed by the locking member 363, thereby improving the subsequent clamping and fixing effect of the NdFeB.

[0033] like Figure 3 to Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The silo 4 includes two half-frames 41 arranged opposite to each other, wherein one half-frame 41 is arranged on the positioning frame 31, and the other half-frame 41 is arranged on the moving frame 33; the NdFeB is located in the two half-frames 41 and mounted on the positioning frame 31 and the moving frame 33, and a notch for the NdFeB to pass through is provided at the bottom of the two half-frames 41 on one side facing the clamping plate 34.

[0034] The NdFeB is stacked in two half-frames 41. When the position of the mobile frame 33 is adjusted by adjusting the positioning member 36 according to the size of the NdFeB, the half-frame 41 on the mobile frame 33 moves with it, and then the distance between the two half-frames 41 can be adjusted synchronously, so that the silo 4 can be used for NdFeB of different sizes, which improves the overall convenience of operation. When feeding the NdFeB, the feeding mechanism 5 pushes the NdFeB at the bottom of the silo 4 through the notch. By feeding the NdFeB at the bottom of the silo 4 one by one, the space occupied by the feeding mechanism 5 can be reduced.

[0035] Furthermore, a mounting frame 9 located on one side of the silo 4 is fixed on the positioning frame 31 , a detection sensor 91 is arranged on the top of the mounting frame 9 , and the detection sensor 91 is used to detect whether there is neodymium iron boron in the silo 4 , and the detection sensor 91 forms a detection area 92 toward the inside of the silo 4 .

[0036] like Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The feeding mechanism 5 includes a feeding linear module 51, a feeding cylinder 52, a cross plate 53 and a push plate 54. The feeding linear module 51 is arranged on the cutting table 2 and is located on one side of the positioning frame 31. The feeding cylinder 52 is vertically arranged on the slide of the feeding linear module 51; one end of the cross plate 53 is fixed on the piston rod of the feeding cylinder 52, and the other end of the cross plate 53 extends to the bottom of the silo 4; the push plate 54 is fixed on the cross plate 53 and faces the gap between the two half frames 41. The push plate 54 is used to push the lowermost neodymium iron boron in the silo 4 out of the notch; the two clamping plates 34 have slideways for the neodymium iron boron to slide in.

[0037] When it is necessary to load NdFeB, the feeding cylinder 52 drives the cross plate 53 to rise and fall, so that the top of the push plate 54 is adjusted to face the lowest NdFeB in the silo 4, and the feeding linear module 51 is started to drive the feeding cylinder 52 and the cross plate 53 to move toward the clamping plate 34, so that the push plate 54 pushes the lowest NdFeB out of the notch of the silo 4 and pushes it into the slideway on the two clamping plates 34, and the feeding of the NdFeB is completed. After the feeding is completed, the feeding cylinder 52 drives the cross plate 53 to descend again, so that the top of the push plate 54 is lower than the lowest NdFeB in the silo 4, and the feeding linear module 51 drives the feeding cylinder 52 to reset, thereby improving the feeding efficiency of the NdFeB at the bottom of the silo 4, occupying less space and convenient maintenance.

[0038] like Figure 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The screening mechanism 6 includes a feed box 61, a partition 62, a screening box 63 and a reciprocating assembly 64; the feed box 61 is slidably arranged in the machine body 1 and is located below the feed port 21, the partition 62 is arranged in the feed box 61 and its internal space is divided into a finished product area 611 at the top, a waste area 612 at the bottom and a discharge area 613 at the side, the partition 62 is inclined at a position above the waste area 612 and is provided with a first screen hole 621 for feeding blocks and slag to fall; the screening box 63 is slidably arranged in the waste area 612 and is located below the first screen hole 621, and a plurality of second screen holes 631 for feeding slag to fall are provided at the bottom of the screening box 63; the reciprocating assembly 64 is used to drive the screening box 63 to move back and forth.

[0039] The slag generated during laser cutting, the cut material blocks and the cut NdFeB all fall into the discharge box 61 through the discharge port 21. Since the diameter of the first sieve hole 621 is larger than the slag and the material blocks, but smaller than the NdFeB, the slag and the material blocks will directly fall into the screening box 63 through the first sieve hole 621, and the NdFeB will slide along the inclined partition 62 to the discharge area 613; the reciprocating assembly 64 drives the screening box 63 to shake back and forth, so that the slag in the screening box 63 can fall into the bottom of the waste area 612 through the second sieve hole 631, and the material blocks remain in the screening box 63, thereby realizing the separate separation of the slag, material blocks and NdFeB.

[0040] like Figure 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: Second slide rails 7 are provided on both sides of the waste area 612, and both sides of the screening box 63 are slidably connected to the corresponding second slide rails 7; the end of the second slide rail 7 close to the discharge area 613 is rotatably connected to the discharge box 61; a connecting plate 71 is fixed between the ends of the two second slide rails 7 away from the discharge area 613; a discharge cylinder 72 is invertedly installed in the discharge box 61, and the top of the discharge cylinder 72 is hinged in the discharge box 61, and the bottom end of the piston rod of the discharge cylinder 72 is hinged to the connecting plate 71; a discharge port 622 is opened on the partition 62 located between the waste area 612 and the discharge area 613, and a transition plate 623 is fixed on the partition 62 at the position of the bottom wall of the discharge port 622, and the transition plate 623 extends obliquely to the bottom of the screening box 63, and the screening box 63 has an opening at the bottom of one side facing the discharge port 622.

[0041] When the reciprocating assembly 64 drives the screening box 63 to reciprocate, the screening box 63 reciprocates on the two second slide rails 7; when taking the material after the screening is completed, the NdFeB in the discharging area 613 is first taken out, and then the two second slide rails 7 are driven to rotate through the connecting plate 71 by the unloading cylinder 72, so that the screening box 63 is tilted accordingly, and the material blocks in the screening box 63 slide out through the opening onto the transition plate 623, and slide from the transition plate 623 through the discharging port 622 into the discharging area 613, so that the material blocks can be taken out, thereby improving the efficiency of taking out the material blocks in the screening box 63. After the material blocks in the screening box 63 slide out, the unloading cylinder 72 drives the two second slides and the screening box 63 to reset through the connecting plate 71.

[0042] like Figure 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: A support plate 73 is fixed on one side of the unloading box 61 away from the discharge area 613, and a coil spring 74 is arranged below the support plate 73. The outer end of the coil spring 74 passes through the support plate 73 upward and is fixed to the connecting plate 71; when the coil spring 74 is in a natural state, the bottom surface of the connecting plate 71 is attached to the support plate 73.

[0043] When there is no need to remove the material blocks in the screening box 63, the connecting plate 71 is supported on the supporting plate 73, and the coil spring 74 further stabilizes the connecting plate 71, thereby ultimately improving the stability of the second slide rail 7 when the screening box 63 reciprocates.

[0044] like Figure 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The reciprocating assembly 64 includes a driving motor 641, a cam 642 and a return spring 643. The driving motor 641 is vertically mounted on the connecting plate 71. The cam 642 is fixed on the output shaft of the driving motor 641 and is used to push the screening box 63. The return spring 643 is laterally connected between the connecting plate 71 and the screening box 63.

[0045] When the slag needs to be screened, the drive motor 641 is started to rotate the cam 642 , and the cam 642 pushes the screening box 63 and cooperates with the return spring 643 to realize the reciprocating movement of the screening box 63 , thereby improving the reciprocating movement efficiency of the screening box 63 .

[0046] When discharging the material blocks, the reciprocating assembly 64 rotates following the connecting plate 71, and drives the screening box 63 to reciprocate along the second slide rail 7 again when the screening box 63 is tilted, so that the material blocks in the screening box 63 can fall out of the screening box 63 more thoroughly and quickly, thereby improving the discharging efficiency of the material blocks.

[0047] like Figures 5 and 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: A cleaning linear module 8 is horizontally arranged on both sides of the top of the unloading box 61, and a cleaning cylinder 81 is invertedly installed on the slide of the cleaning linear module 8. A cleaning plate 82 is fixed to the bottom end of the piston rod of the cleaning cylinder 81. A receiving groove 821 is opened on the top of the cleaning plate 82, and a compression spring 83 and a scraper 84 are arranged in the receiving groove 821. The top end of the scraper 84 is slidably arranged in the receiving groove 821 and is connected to the compression spring 83, and the bottom end of the scraper 84 is located below the receiving groove 821.

[0048] Furthermore, when the cleaning plate 82 is in the initial position, it is close to the bottom end of the inclined surface of the partition plate 62 .

[0049] When it is necessary to clean the upper surface of the partition 62, the two cleaning cylinders 81 first synchronously drive the cleaning plate 82 to descend, so that the bottom end of the scraper 84 contacts the upper surface of the partition 62; then the two cleaning linear modules 8 are started synchronously to drive the cleaning cylinder 81 to move toward the top end of the inclined surface of the partition 62, and the scraper 84 will scrape the slag or block that may remain on the upper surface of the partition 62 upward to make it fall out of the first sieve hole 621, and at the same time, the compression spring 83 is continuously contracted, so that the friction between the scraper 84 and the partition 62 is increasingly greater, further improving the cleaning effect of the upper surface of the partition 62; after the upper surface of the partition 62 is cleaned, the cleaning cylinder 81 drives the upper part of the cleaning plate 82 to reset, and at the same time, the cleaning linear module 8 drives the cleaning cylinder 81 to reset, and finally the distance between the bottom of the partition 62 and the upper surface of the partition 62 is sufficient for the NdFeB to pass through, thereby finally improving the separation effect of the slag, block and NdFeB.
