Description

Technical Field

[0001] The invention relates to the technical field of magnet processing, and in particular to a NdFeB magnet cutting device which is easy to fix. Background Art

[0002] With the development of science and technology, NdFeB magnetic materials are widely used in various electronic products due to their excellent magnetic properties. This high-performance permanent magnetic material is composed of neodymium, iron, boron and other elements to form a crystal with a tetragonal crystal structure. In order to meet different application requirements, NdFeB magnets need to be precisely cut into small pieces of specific sizes and shapes during the manufacturing process. However, at the moment when the NdFeB magnets are cut, the small NdFeB magnets cut into two halves will be repelled from each other, causing the two small NdFeB magnets to be instantly bounced apart. This not only has a certain adverse effect on nearby operators and machinery and equipment, but may also affect the quality and efficiency of cutting.

[0003] At present, in order to ensure the stability and safety of NdFeB magnets during cutting, glue is usually used to fix the NdFeB magnets to be cut on the workbench; the specific method is to first stack the magnets neatly according to the predetermined position and order, and then manually apply glue on the top and side surfaces of the magnets, so that the glue penetrates into the gaps between the magnets and the gaps between the bottom magnets and the top surface of the storage table, so as to fix the magnets; although this method can achieve the fixing effect to a certain extent, since the glue mainly relies on surface contact and natural penetration, it is difficult to evenly and fully cover the gaps between all magnets, especially the gaps in the middle area of ​​the magnets, which leads to poor fixing effect in the middle area of ​​the magnets, resulting in that in actual operation, when the cutting tool reaches the middle of the magnet, due to poor fixation, the small magnets cut off are easily affected by the internal magnetic field and suddenly pop out, which not only increases the risk of safety accidents, but also affects the quality and consistency of the cut products. In addition, the manual gluing method also has problems such as low efficiency and high labor intensity, which is difficult to meet the requirements of modern manufacturing industry for production efficiency and automation. Summary of the invention

[0004] In view of this, the present invention provides a NdFeB magnet cutting device that is easy to fix, which can solve the problem that when glue is manually applied to the top and side surfaces of the magnets, it is difficult to evenly and fully cover all the magnets only by surface contact and natural penetration of the glue, resulting in poor fixing effect in the middle area of ​​the magnet. In addition, the manual gluing method also has the disadvantages of low efficiency and high labor intensity.

DETAILED DESCRIPTION

The machine table 1 is installed with a water collecting frame 301, and the water collecting frame 301 is located directly below the multi-wire cutting device 2. The machine table 1 is slidably provided with a filter frame 302, and the filter frame 302 is located between the multi-wire cutting device 2 and the water collecting frame 301.

The rear side of the machine table 1 is also connected to a spray pipe 304, and one end of the spray pipe 304 is connected to the water outlet end of the water pump 303. The spray pipe 304 is connected to the rear side of the machine table 1. The other end of 04 is located on the inner side of the machine 1. When in use, a proper amount of coolant is added to the water collecting frame 301, and then the coolant in the water collecting frame 301 is pumped into the spray pipe 304 through the water pump 303, so that the spray pipe 304 sprays the coolant on the NdFeB magnet 101, thereby cooling the NdFeB magnet 101 to prevent the NdFeB magnet 101 from deforming due to excessive temperature during cutting. At the same time, the coolant sprayed by the spray pipe 304 can also cool the fine wire of the multi-wire cutting device 2 to avoid serious wear of the fine wire, thereby extending the working life of the fine wire. The sprayed coolant will fall down to the filter frame 302 under the influence of gravity for filtration, so that the impurities carried by the coolant remain in the filter frame 302, and the coolant passes through the filter frame 302 and falls back into the water collecting frame 301 for recycling.

In this way, the glue can be evenly dispersed in the gap between the NdFeB magnet 101 and the adjacent object, so that each position on the NdFeB magnet 101 is adhered to the adjacent object through the glue, thereby improving the fixity of each position on the NdFeB magnet 101. When the glue flows out from the gap between the closed frame 10 and the storage table 5 and the first groove 501, the second groove 502 and the collection frame 6 collect the glue flowing out of the gap between the closed frame 10 and the storage table 5 and the first groove 501 to prevent the glue from flowing to the ground; a rotating arrangement is provided between the rear side of the first slide rail 4 and the inner rear wall of the machine table 1.

[0038] See also Fig.10 and Fig.11As shown, the discharging mechanism includes a connecting frame 1601, a movable plate 1602, a second servo motor 1603, a first bidirectional screw rod 1604 and a fixed rod 1605; the connecting frame 1601 is connected to the rear side of the first servo motor 1501; the lower side of the connecting frame 1601 is slidably connected to two movable plates 1602, and the two movable plates 1602 are respectively located on the left and right sides of the connecting frame 1601, and the top surface of the movable plate 1602 is flush with the bottom surface of the second slide groove at the lower side of the second slide rail 13, so that the storage table 5 can slide to the bottom of the two movable plates 1602 through the second slide rail 13, and the two L-shaped connecting plates of the storage table 5 are respectively hooked on the two movable plates 1602; the second servo motor 1603 is installed on the lower left side of the connecting frame 1601, and the first bidirectional screw rod 1604 is rotatably set at the rear part of the lower side of the connecting frame 1601 , and the left end of the first bidirectional screw rod 1604 is connected to the output shaft of the second servo motor 1603, and the left and right ends of the first bidirectional screw rod 1604 are respectively threadedly connected to the left and right movable plates 1602, and the second servo motor 1603 is used to drive the first bidirectional screw rod 1604 to rotate, and the first bidirectional screw rod 1604 is used to drive the two movable plates 1602 to approach each other through rotation to loosen the two L-shaped connecting plates of the storage table 5, so that the storage table 5 and the neodymium iron boron magnet 101 thereon fall down under gravity to discharge the material; a fixed rod 1605 is connected to the bottom of the gear box 1502, and the left and right ends of the fixed rod 1605 are respectively slidably connected to the left and right movable plates 1602, and the fixed rod 1605 is used to stabilize the front sides of the two movable plates 1602 to prevent the front sides of the two movable plates 1602 from being compressed and deformed.

[0039] When in use, add an appropriate amount of glue into the liquid storage tank 7, then manually push the storage table 5 from front to back onto the first slide rail 4, and make the L-shaped connecting plate on the storage table 5 snap into the first slide groove of the first slide rail 4, and then place the NdFeB magnet 101 on the top of the storage table 5 (such as Figure 5As shown in the figure, when stacking the NdFeB magnets 101, it is necessary to ensure that the stacked NdFeB magnets 101 do not affect the downward movement of the closed frame 10, and the height of the stacked NdFeB magnets 101 needs to be smaller than the inner height of the closed frame 10). Then, the closed frame 10 is driven downward by the first electric push rod 9 to make the bottom surface of the closed frame 10 contact with the top surface of the storage table 5, so that the closed frame 10 can seal the stacked NdFeB magnets 101 on the top of the storage table 5. Then, the high-viscosity asphalt pump 8 is used to pump the glue in the liquid storage tank 7 into the sealing tank through the feed pipe 11. In the closed frame 10, the glue is filled from top to bottom between the NdFeB magnet 101 and the adjacent object (the adjacent object refers to the NdFeB magnet 101, the closed frame 10 and the storage table 5). In this way, the glue can be evenly dispersed in the gap between the NdFeB magnet 101 and the adjacent object, so that each position on the NdFeB magnet 101 is adhered to the adjacent object through the glue (because the inner wall of the closed frame 10 is coated with an anti-stick coating, the glue will not adhere to the inner wall of the closed frame 10), thereby improving each position on the NdFeB magnet 101. Fixation, when the glue flows out from the gap between the closed frame 10 and the storage table 5 and the first groove 501, the second groove 502 and the collection frame 6 can be used to collect the glue flowing out of the gap between the closed frame 10 and the storage table 5 and the first groove 501 to prevent the glue from flowing to the ground. When the NdFeB magnet 101 is fixed, the first electric push rod 9 drives the closed frame 10 to move upward and reset, so that the bottom surface of the closed frame 10 is separated from the top surface of the storage table 5, and then wait for the glue on the NdFeB magnet 101 to solidify, and wait for the NdFeB magnet 101 to be fixed. After the glue on 101 solidifies, the platform 5 is manually pushed to move backward, so that the platform 5 slides backward from the first slide rail 4 to the second slide rail 13, and the L-shaped connecting plate of the platform 5 is inserted into the second slide groove on the upper side of the second slide rail 13. When the rear side of the platform 5 contacts the gear box 1502, the limiting frame 1402 is driven to move upward by the second electric push rod 1401, so that the limiting frame 1402 contacts the front side of the platform 5 on the second slide rail 13, and the limiting frame 1402 limits the platform 5 on the second slide rail 13 (such as Fig. 9As shown in the figure, the multi-wire cutting device 2 is controlled to move downward to cut the NdFeB magnet 101 on the platform 5, and the cooling device 3 is started to cool the NdFeB magnet 101 and the thin wires on the multi-wire cutting device 2 until the thin wires in the multi-wire cutting device 2 have completely cut the NdFeB magnet 101 and enter the first groove 501, and then the multi-wire cutting device 2 is controlled to move upward to reset, and the cooling device 3 is turned off, and then The second electric push rod 1401 drives the limiting frame 1402 to move downward and reset, so that the limiting frame 1402 is separated from the front side of the storage table 5 on the second slide rail 13, and the limiting frame 1402 releases the limiting of the storage table 5 on the second slide rail 13. Then, the first servo motor 1501 drives the rotating shaft 12 and the second slide rail 13 to rotate 180 degrees through the transmission of the gear box 1502, so that the storage table 5 and the cut NdFeB magnet 101 rotate 180 degrees along with the second slide rail 13 (such as Fig.11 As shown), the storage platform 5 is manually pushed to move backward, so that the storage platform 5 slides backward from the second slide rail 13 to the two movable plates 1602, and the L-shaped connecting plate of the storage platform 5 is hooked on the two movable plates 1602, and then the first bidirectional screw rod 1604 is driven by the second servo motor 1603 to rotate, so that the first bidirectional screw rod 1604 drives the two movable plates 1602 to move toward the side close to each other, so that the two movable plates 1602 gradually align with the L-shaped connecting plate of the storage platform 5. The connecting plate is separated. When the two movable plates 1602 are completely separated from the L-shaped connecting plate of the storage table 5, the storage table 5 and the NdFeB magnets 101 cut thereon will fall down due to the influence of gravity, and then the first bidirectional lead screw 1604 is driven by the second servo motor 1603 to reverse and reset, so that the first bidirectional lead screw 1604 drives the two movable plates 1602 to move to the side away from each other and reset, and then repeat the above operation to repeatedly cut the NdFeB magnets 101.

[0040] See also Fig.12 As shown, it also includes a pushing mechanism, which includes a first hydraulic cylinder 17 and a pushing plate 18; the first hydraulic cylinder 17 is connected to the left and right sides of the first slide rail 4; the pushing plate 18 is connected between the telescopic rods of the two first hydraulic cylinders 17, and the pushing plate 18 is driven by the first hydraulic cylinder 17 to move backward, so that the pushing plate 18 can push the storage table 5 under the second slide rail 13 onto the two movable plates 1602.

[0041] When it is necessary to manually push the storage table 5 backward so that the storage table 5 slides backward from the second slide rail 13 to the two movable plates 1602, the first hydraulic cylinder 17 can be controlled to drive the push plate 18 to move backward, so that the push plate 18 pushes the storage table 5 under the second slide rail 13 backward to the two movable plates 1602, and then the first hydraulic cylinder 17 is controlled to drive the push plate 18 to move forward and reset. In this way, the storage table 5 can be automatically pushed, thereby saving the workers' physical strength.

[0042] See also Figure 13-Figure 15 As shown, it also includes a feeding mechanism, which includes a connecting platform 19, a second hydraulic cylinder 20, a guide rail 21, a guide rod 22, a storage plate 23, a spring 24, a fixing block 25, a limit clamp 26 and a driving member; a connecting platform 19 is installed on the right side of the middle of the front side of the machine 1; two second hydraulic cylinders 20 are symmetrically installed on the top of the connecting platform 19; a guide rail 21 is connected between the telescopic rods of the two second hydraulic cylinders 20; a guide rod 22 is symmetrically arranged on the lower right side of the guide rail 21; a storage plate 23 for stacking NdFeB magnets 101 is slidably arranged between the two guide rods 22, and the top surface of the storage plate 23 is flush with the top surface of the storage platform 5; a spring 24 is connected between the right end of the guide rod 22 and the right side of the storage plate 23; a guide rail 21 is connected to the left middle of the guide rail 21 A fixed block 25 is connected; the front and rear sides of the left side of the guide rail 21 are slidably connected to the limit clamp 26, and the limit clamp 26 and the fixed block 25 are used to limit the NdFeB magnet 101 on the storage plate 23; the driving part includes a second bidirectional screw 27 and a third servo motor 28, and the second bidirectional screw 27 is rotatably arranged on the inner side of the guide rail 21, and the front and rear limit clamps 26 are respectively threadedly connected to the front and rear ends of the second bidirectional screw 27; the front side of the guide rail 21 is connected to the third servo motor 28, and the output shaft of the third servo motor 28 is connected to the front end of the second bidirectional screw 27, and the third servo motor 28 is used to drive the second bidirectional screw 27 to rotate, so that the second bidirectional screw 27 can drive the limit clamp 26 to move through rotation.

[0043] When in use, the NdFeB magnet 101 can be placed in advance at a designated position on the top of the storage plate 23 (such as Fig.14As shown), when the storage platform 5 is manually pushed onto the first slide rail 4 from the front to the back, the second bidirectional screw 27 can be driven to rotate by the third servo motor 28, so that the second bidirectional screw 27 drives the two limit clamps 26 to move toward the side close to the fixed block 25, until the limit clamps 26 and the fixed block 25 complete the fixation of the NdFeB magnet 101 on the top of the storage plate 23, and then the guide rail 21 is driven to move to the left by the second hydraulic cylinder 20, so that the guide rail 21 drives the fixed block 25 , the limiting clamp 26, the guide rod 22, the storage plate 23 and the stacked NdFeB magnets 101 move to the left. When the left side of the storage plate 23 contacts the right side of the storage table 5, the right side of the storage table 5 blocks the storage plate 23, so that the storage plate 23 stops moving. When the guide rail 21 drives the fixing block 25, the limiting clamp 26, the guide rod 22 and the stacked NdFeB magnets 101 to continue to move to the left, the spring 24 is compressed, and the fixing block 25 and the limiting clamp 26 will move the stacked NdFeB magnets 101 to the left. The boron magnet 101 is brought from the storage plate 23 to the top of the storage table 5 until the stacked NdFeB magnet 101 is at the specified position on the top of the storage table 5, and then the third servo motor 28 drives the second bidirectional screw rod 27 to reverse and reset, so that the second bidirectional screw rod 27 drives the two limit clamps 26 to move and reset to the side away from the fixed block 25, so that the limit clamps 26 and the fixed block 25 release the NdFeB magnet 101 on the top of the storage table 5, and then the second hydraulic cylinder 20 drives the second bidirectional screw rod 27 to reverse and reset, so that the second bidirectional screw rod 27 drives the two limit clamps 26 to move and reset to the side away from the fixed block 25, so that the limit clamps 26 and the fixed block 25 release the NdFeB magnet 101 on the top of the storage table 5. The movable guide rail 21 moves to the right and resets, so that the guide rail 21 drives the fixed block 25, the limit clamp 26 and the guide rod 22 to move to the right and reset. During this period, the spring 24 gradually returns to its original state. When the spring 24 is reset, the guide rod 22 will pull the placement plate 23 to the right and reset through the spring 24, so that the left side of the placement plate 23 is separated from the right side of the placement table 5. In this way, the stacked NdFeB magnets 101 can be quickly transferred to the top of the placement table 5, so that the next step of operation can be quickly carried out, thereby speeding up work efficiency.

[0044] See also Fig.14 and Fig.15 As shown, it also includes a strip plate 29; the strip plates 29 are arranged at intervals at the bottom of the guide rail 21, the strip plates 29 are aligned with the first grooves 501 on the storage table 5, and the number of the strip plates 29 and the first grooves 501 is the same, and the strip plates 29 are used to push out foreign objects in the first grooves 501.

[0045] When the guide rail 21 moves to the left, the guide rail 21 will drive the strip plate 29 to move to the left synchronously, so that the strip plate 29 extends into the first groove 501 on the storage table 5, so that the strip plate 29 pushes the foreign matter in the first groove 501 to the left, and then cleans the foreign matter in the first groove 501 to prevent the foreign matter from affecting the fine wire of the subsequent multi-wire cutting device 2 to enter the first groove 501, and the foreign matter pushed out by the strip plate 29 will fall into the collection frame 6 on the left for collection; when the guide rail 21 moves to the right to reset, the guide rail 21 will drive the strip plate 29 to move to the right to reset synchronously, so that the strip plate 29 leaves the first groove 501 on the storage table 5.
