Description

Technical Field

[0001] This invention belongs to the technical field of neodymium iron boron (NdFeB) cutting and processing equipment, and specifically relates to a NdFeB magnet cutting device. Background Technology

[0002] Cutting is a crucial step in the manufacturing of neodymium iron boron magnets. Existing cutting equipment often requires extensive manual operation, including manual loading, positioning, and unloading. This manual intervention is not only inefficient but also prone to introducing human error, affecting product quality and consistency. Due to reliance on manual operation, the speed of the entire cutting process is limited, hindering continuous and efficient production. Especially in mass production, manual operation becomes a bottleneck, severely impacting overall production efficiency. Furthermore, in traditional cutting processes, operators must directly contact hazardous areas such as high-speed rotating blades or high-temperature laser beams, posing a high risk of workplace injuries. In addition, manually securing the workpiece is not secure enough, easily leading to accidents due to workpiece loosening.

[0003] In summary, existing neodymium iron boron magnet cutting devices have significant shortcomings in terms of automation, production efficiency, safety, precision, and flexibility. There is an urgent need for a more efficient, safe, and flexible cutting device to meet the needs of modern industrial production. Summary of the Invention

The ejector pin and the chuck cooperate to fix the NdFeB workpiece.

[0008] The feeding mechanism includes a cassette, an ejection assembly, and a conveying assembly. The cassette has a loading cavity for placing NdFeB workpieces. The ejection assembly ejects the NdFeB workpieces located in the loading cavity from the cassette.

[0013] As a preferred technical solution for a neodymium iron boron magnet cutting device, the air flow direction of both the air guide port and the air collection port is tangent to the inner wall of the manifold.

[0014] As a preferred technical solution for a neodymium iron boron magnet cutting device, the clamping mechanism further includes a blanking assembly, which comprises a blanking cylinder, a connecting rod, and a blanking pusher rod. The connecting rod is hinged to the base in the middle, one end of the connecting rod is connected to the blanking cylinder, and the other end is connected to the blanking pusher rod. The clamping plate is provided with a slot for fixing the neodymium iron boron workpiece, and a through groove is provided at the bottom of the slot, through which the blanking pusher rod is sleeved.

[0015] As a preferred technical solution for a neodymium iron boron magnet cutting device, the loading chamber has an open top, and during loading, the neodymium iron boron workpieces are neatly arranged in the loading chamber with the same orientation. The loading chamber is divided into a placing section and a discharging section, and the ejection assembly is assembled on one side of the discharging section.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] In the following embodiments, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] In the description of this invention, it should be understood that terms such as center, longitudinal, transverse, length, width, thickness, upper, lower, front, rear, left, right, vertical, horizontal, top, bottom, inner, outer, clockwise, counterclockwise, etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing and simplifying the description of this invention; therefore, they should not be construed as limiting this invention. Furthermore, terms such as first, second, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this invention, unless otherwise expressly specified and limited, terms such as installation, connection, linking, etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Reference Figures 1 to 11 A neodymium iron boron magnet cutting device is used to cut a cylindrical neodymium iron boron workpiece 120. It includes a base 100, a material discharge port 110 is provided in the middle of the base 100, and a cutting mechanism 200, a clamping mechanism 300 and a feeding mechanism 400 are assembled on the base 100 around the material discharge port 110.

[0036] The cutting mechanism 200 includes a mounting frame 210, on which a transverse sliding module 220 is mounted. A lifting sliding module 230 is mounted on the transverse sliding module 220, and a lifting base plate is mounted on the lifting sliding module 230. A laser cutting module 240 is mounted on the lifting base plate. A laser head 241 is located at the bottom of the laser cutting module 240, and a nozzle 242 is located at the bottom of the laser head 241. The laser head 241 is equipped with a cooling pipe and an auxiliary gas port 244. The cooling pipe is externally connected to a cooling circulation system, and the auxiliary gas port 244 is externally connected to an air pump. The design of the cooling pipe effectively reduces the temperature of the laser head 241 during operation, ensuring its stability and service life. The auxiliary gas port 244 is used to introduce auxiliary gas to remove slag generated during the cutting process, improving cutting quality and efficiency.

[0037] The cooling pipeline includes a transparent tube 243, which is exposed outside the laser head 241. The transparent tube 243 allows users to directly observe the circulation of the coolant within the cooling pipeline, facilitating timely detection of issues such as abnormal coolant flow, air bubbles, or blockages. Furthermore, a temperature detection module can be installed on the transparent tube 243 to monitor the coolant temperature in real time, aiding in rapid diagnosis of cooling system faults, improving maintenance efficiency, and reducing downtime.

[0038] Furthermore, the laser head 241 is equipped with a manifold 250. The manifold 250 has a processing area 251 in the center to accommodate the NdFeB workpiece 120, and an opening 252 at the bottom for the NdFeB workpiece 120 to pass through. The nozzle 242 is located within the processing area 251, and the processing area 251 has a guide air port 253 and a collection air port 254 on its left and right sides, respectively. The guide air port 253 ejects airflow, which flows through the processing area 251 and enters the collection air port 254, collecting molten slag along the way. This improves cutting quality and efficiency while protecting the laser head 241 from damage by the molten slag. This design effectively collects the molten slag generated during the cutting process, preventing it from scattering and contaminating the working environment.

[0039] The laser head 241 is provided with a positioning surface 245, and the manifold 250 is provided with an adapter surface 257 that matches the positioning surface 245. The design of the positioning surface 245 and the adapter surface 257 ensures precise positioning between the manifold 250 and the laser head 241, improving the accuracy and stability of the installation. The manifold 250 and the laser head 241 are fixedly connected by a fixing assembly 260. The fixing assembly 260 includes a cylindrical base 261 and a pulling shaft 262. The cylindrical base 261 is provided with a sliding cavity, and the pulling shaft 262 is assembled in the sliding cavity. One end of the pulling shaft 262 extends from the top of the cylindrical base 261 and is provided with a pulling block 263. The other end of the pulling shaft 262 is provided with a stop 264, and a spring 266 is assembled between the stop 264 and the top wall of the sliding cavity. The abutment 264 is provided with a fixing head 265, and the side of the laser head 241 is provided with a fixing hole 258 that mates with the fixing head 265. The user can easily remove the manifold 250 from the laser head 241 by pulling out the pull block 263. The operation is simple and quick, and it is convenient for maintenance and replacement.

[0040] As one embodiment of the manifold 250, baffles 255 are provided on both the front and rear sides of the manifold 250. The baffles 255 and the inner wall of the manifold 250 cooperate to form an airflow groove 256. The airflow direction of the guide air port 253 and the collection air port 254 is tangent to the inner wall of the manifold 250. This design allows the airflow groove 256 to confine the molten slag within the processing area 251 as much as possible, improving the slag collection efficiency. At the same time, the design of the guide air port 253 and the collection air port 254 being tangent to the inner wall of the manifold 250 can avoid the airflow colliding with the inner wall, reduce airflow turbulence, and thus prevent the molten slag from being carried out of the manifold 250 by the turbulent airflow, ensuring a clean working environment. The opening 252 divides the manifold 250 into a left half and a right half. The lower parts of the left half and the right half are both arc-shaped, and the tangent lines tangent to the bottom of the left half and the right half are collinear. The guide port 253 is located in the left half of the cover, and the collection port 254 is located in the right half of the cover. The airflow ejected from the guide port 253 can enter the right half of the cover through the opening 252 along the inner wall of the left half of the cover, and then be collected by the collection port 254. The tangential collinear design is intended to prevent the airflow from escaping outside the manifold 250 when passing through the opening 252, reduce gas waste, and prevent molten slag from being carried out of the manifold 250, thereby improving gas utilization and the cleanliness of the working environment.

[0041] As another embodiment of the manifold 250, the difference between this embodiment and the previous embodiment is that the manifold 250 is capsule-shaped. The capsule-shaped manifold 250 can more effectively guide airflow, reduce airflow turbulence and disturbance, and make the airflow flow more smoothly from the guide air port 253 to the collection air port 254, thereby improving the gas transmission efficiency and ensuring that the gas flows inside the manifold 250 without escaping into the external environment.

[0042] The clamping mechanism 300 includes a first clamp 310 and a second clamp 320, which are respectively disposed on both sides of the discharge port 110. The first clamp 310 includes a base 311, on which a clamping plate 312 and an adjusting motor 313 are mounted. The adjusting motor 313 drives the clamping plate 312 to rotate and adjust the angle of the NdFeB workpiece 120. The second clamp 320 includes a clamping sliding module 321, on which a slide block 322 is mounted. The slide block 322 is mounted with a ejector pin 323, which cooperates with the clamping plate 312 to fix the NdFeB workpiece 120.

[0043] The clamping mechanism 300 further includes a blanking assembly 330, which comprises a blanking cylinder 331, a connecting rod 332, and a blanking pusher rod 333. The connecting rod 332 is hinged to the base 311 in the middle, with one end connected to the blanking cylinder 331 and the other end connected to the blanking pusher rod 333. The clamping plate 312 is provided with a slot for fixing the NdFeB workpiece 120, and a through groove is provided at the bottom of the slot, through which the blanking pusher rod 333 is sleeved. This design ensures that the workpiece can be smoothly pushed out after processing, facilitating blanking and subsequent processing, and improving the automation level and work efficiency of the overall production line.

[0044] The feeding mechanism 400 includes a hopper 410, an ejection assembly 420, and a conveying assembly 430. The hopper 410 has a loading cavity for placing NdFeB workpieces 120. The ejection assembly 420 ejects the NdFeB workpieces 120 located in the loading cavity from the hopper 410. The conveying assembly 430 receives the NdFeB workpieces 120 ejected from the hopper 410 and delivers them to the clamping mechanism 300.

[0045] Specifically, the loading chamber has an opening at the top. During loading, the NdFeB workpieces 120 are neatly arranged in the loading chamber with the same orientation. The loading chamber is divided into a placement section 411 and a discharge section 412. The ejection assembly 420 is assembled on one side of the discharge section 412. The discharge section 412 is vertically arranged, and the connection between the placement section 411 and the discharge section 412 is smoothly transitioned. This design ensures that the workpiece transitions smoothly from the placement section 411 to the discharge section 412, reducing jamming and damage, and improving the workpiece's flowability and stability. The ejection assembly 420 includes a fixing frame 421, on which a pusher cylinder 422 is mounted. The pusher cylinder 422 is connected to a feeding pusher rod 423. Pushing holes and discharge holes are respectively provided on both sides of the lowest point of the discharge section 412. The feeding pusher rod 423 is located in the pushing hole, and the conveying assembly 430 is located on one side of the discharge hole. The handling assembly 430 includes a handling sliding module 431, on which a clamping cylinder 432 is connected. The clamping cylinder 432 is connected to a pneumatic gripper 433 adapted to the NdFeB workpiece 120. This design enables precise gripping and handling of the workpiece, improves the stability and accuracy of handling, reduces damage to the workpiece during handling, and ensures the smooth progress of subsequent processing.

[0046] To prevent the NdFeB workpieces 120 from getting stuck due to overcrowding when entering the unloading section 412, an anti-jamming motor 440 is also installed on the fixing frame 421. The anti-jamming motor 440 is connected to an anti-jamming wheel 441, which is located at the connection between the unloading section 412 and the placement section 411. The anti-jamming wheel 441 is surrounded by partition plates, forming a space between adjacent partition plates that can accommodate the NdFeB workpieces 120. Driving the anti-jamming wheel 441 to rotate via the anti-jamming motor 440 allows the NdFeB workpieces 120 to enter the unloading section 412, effectively preventing them from getting stuck due to overcrowding. This design ensures smooth workpiece flow, improves production efficiency, and reduces downtime and equipment damage risks caused by jamming.

Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
