In the production process, accurate cutting technology is crucial to the performance and quality of NdFeB magnets. At present, laser cutting technology has been widely used in the cutting process of NdFeB magnets due to its advantages such as high precision and high speed. However, traditional laser cutting equipment has some shortcomings in dealing with the slag generated during the cutting process:

[0003] 1. Inconvenient slag treatment: In the traditional laser cutting process, the slag produced by cutting often scatters on the workbench in a large area. These slags are not only difficult to clean, but may also adhere to the surface of the workbench, affecting the accuracy and quality of subsequent processing.

[0035] Reference Figures 1 to 11 A NdFeB magnet cutting device is used for cutting a cylindrical NdFeB workpiece 120, including a base 100, a blanking port 110 is arranged in the middle of the base 100, and a cutting mechanism 200, a clamping mechanism 300 and a feeding mechanism 400 are assembled around the blanking port 110 on the base 100.

[0036] The cutting mechanism 200 includes a mounting frame 210, on which a transverse sliding module 220 is mounted, on which a lifting sliding module 230 is mounted, on which a lifting sliding module 230 is mounted, on which a lifting substrate is mounted, and on which a laser cutting module 240 is mounted. A laser head 241 is arranged at the bottom of the laser cutting module 240, and a nozzle 242 is arranged at the bottom of the laser head 241. A cooling pipeline and an auxiliary gas port 244 are arranged on the laser head 241, and the cooling pipeline 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 pipeline can effectively reduce the temperature of the laser head 241 during operation, and ensure its stability and service life. The auxiliary gas port 244 is used to introduce auxiliary gas to remove the slag generated during the cutting process, thereby improving the cutting quality and efficiency.

[0037] The cooling pipeline includes a transparent tube 243, which is exposed outside the laser head 241. The design of the transparent tube 243 allows the user to visually observe the circulation of the coolant in the cooling pipeline, so as to timely find out whether the flow of the coolant is normal, whether there are bubbles or blockages, etc. In addition, by installing a temperature detection module on the transparent tube 243, the temperature of the coolant can be monitored in real time, which helps to quickly diagnose the failure of the cooling system, improve maintenance efficiency, and reduce downtime.

[0038] Furthermore, the laser head 241 is equipped with a collector 250, and the middle of the collector 250 is a processing area 251 for accommodating the NdFeB workpiece 120, and the bottom of the collector 250 is provided with an opening 252 for the NdFeB workpiece 120 to pass through. The nozzle 242 is located in the processing area 251, and the processing area 251 is provided with a guide air port 253 and a collection air port 254 on the left and right sides of the nozzle 242. The guide air port 253 is used to eject air flow, and the air flow enters the collection air port 254 after passing through the processing area 251, and slag is collected during the process, thereby improving the cutting quality and work efficiency, and protecting the laser head 241 from damage by slag. Such a design can effectively collect the slag generated during the cutting process to prevent it from scattering and polluting the working environment.

[0039] Among them, the laser head 241 is provided with a positioning surface 245, and the collector 250 is provided with an adapting surface 257 adapted to the positioning surface 245. The design of the positioning surface 245 and the adapting surface 257 ensures the precise positioning between the collector 250 and the laser head 241, and improves the accuracy and stability of the installation. The collector 250 and the laser head 241 are fixedly connected by a fixing assembly 260. The fixing assembly 260 includes a cylinder seat 261 and a pulling shaft 262, a sliding cavity is provided in the cylinder seat 261, and the pulling shaft 262 is assembled in the sliding cavity, one end of the pulling shaft 262 extends from the top of the cylinder seat 261 and is provided with a pulling block 263, and 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 stopper 264 is provided with a fixing head 265, and the side of the laser head 241 is provided with a fixing hole 258 that matches the fixing head 265. The user can easily remove the collector 250 from the laser head 241 by pulling out the pull block 263, which is simple and quick to operate and convenient for maintenance and replacement.

[0040] As an embodiment of the collector 250, baffles 255 are provided on both the front and rear sides of the collector 250, and the baffles 255 cooperate with the inner wall of the collector 250 to form an airflow groove 256. The ventilation directions of the guide air port 253 and the collecting air port 254 are tangent to the inner wall of the collector 250. Such a design enables the airflow groove 256 to limit the slag in the processing area 251 as much as possible, thereby improving the collection efficiency of the slag. At the same time, the design that the guide air port 253 and the collecting air port 254 are tangent to the inner wall of the collector 250 can avoid the collision between the airflow and the inner wall, reduce the turbulence of the airflow, thereby preventing the slag from being carried out of the collector 250 by the turbulent airflow, and ensuring the cleanliness of the working environment. The opening 252 divides the collector 250 into a left half cover and a right half cover, and the lower parts of the left half cover and the right half cover are both arc-shaped, and the tangent line tangent to the bottom of the left half cover and the tangent line tangent to the bottom of the right half cover are designed to be collinear. The guide air port 253 is located in the left half cover, and the collecting air port 254 is located in the right half cover. The airflow ejected from the guide air port 253 can enter the right half cover through the opening 252 along the inner wall of the left half cover, and then be collected by the collecting air port 254. The design of the tangent line collinearity is to prevent the airflow from escaping to the outside of the collector cover 250 when passing through the opening 252, reduce gas waste, and prevent slag from being taken out of the collector cover 250, thereby improving gas utilization and the cleanliness of the working environment.

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

[0042] The clamping mechanism 300 includes a first clamp 310 and a second clamp 320, and the first clamp 310 and the second clamp 320 are respectively arranged on both sides of the blanking port 110. The first clamp 310 includes a base 311, and a chuck 312 and an adjustment motor 313 are installed on the base 311. The adjustment motor 313 drives the chuck 312 to rotate and adjust the angle of the NdFeB workpiece 120. The second clamp 320 includes a clamping sliding module 321, and a slide 322 is installed on the clamping sliding module 321. The slide 322 is equipped with an ejector pin 323. The ejector pin 323 and the chuck 312 cooperate to fix the NdFeB workpiece 120.

[0043] The clamping mechanism 300 also includes a blanking assembly 330, which includes a blanking cylinder 331, a connecting rod 332 and a push rod 423. The middle of the connecting rod 332 is hinged to the base 311, one end of the connecting rod 332 is connected to the blanking cylinder 331, and the other end is connected to the push rod 423. The chuck 312 is provided with a slot for fixing the NdFeB workpiece 120, and the bottom of the slot is provided with a through slot that passes through the chuck 312, and the push rod 423 is sleeved in the through slot. This design can ensure that the workpiece can be smoothly pushed out after processing, which is convenient for blanking and subsequent processing, and improves the automation and work efficiency of the overall production line.

[0044] The feeding mechanism 400 includes a magazine 410, an ejection assembly 420 and a conveying assembly 430. The magazine 410 is provided with a loading chamber for placing the NdFeB workpiece 120. The ejection assembly 420 pushes the NdFeB workpiece 120 located in the loading chamber out of the magazine 410. The conveying assembly 430 is used to receive the NdFeB workpiece 120 ejected from the magazine 410 and deliver it to the clamping mechanism 300.

[0045] Specifically, the top opening 252 of the loading chamber is provided, and the NdFeB workpieces 120 are neatly arranged in the loading chamber in a consistent direction during loading. The loading chamber is divided into a loading section 411 and a unloading section 412, and the ejection assembly 420 is assembled on one side of the unloading section 412. The unloading section 412 is arranged vertically, and the connection between the loading section 411 and the unloading section 412 is smoothly transitioned. This design can ensure that the workpiece smoothly transitions from the loading section 411 to the unloading section 412, reduce jamming and damage, and improve the fluidity and stability of the workpiece. The ejection assembly 420 includes a fixed frame 421, and a pushing cylinder 422 is assembled on the fixed frame 421, and the pushing cylinder 422 is connected to a pushing rod 423. A pushing hole and a discharging hole are respectively arranged on both sides of the lowest point of the unloading section 412, and the pushing rod 423 is located in the pushing hole, and the conveying assembly 430 is located on one side of the discharging hole. The transport assembly 430 includes a transport sliding module 431, a clamping cylinder 432 is connected to the transport sliding module 431, and the clamping cylinder 432 is connected to an air gripper 433 adapted to the NdFeB workpiece 120. Such a design can achieve accurate grasping and transport of the workpiece, improve the stability and accuracy of the transport, reduce damage to the workpiece during the transport process, and ensure the smooth progress of subsequent processing.

[0046] In order to prevent the NdFeB workpiece 120 from getting stuck due to overcrowding when entering the unloading section 412, the fixing frame 421 is also equipped with an anti-stuck motor 440, and the anti-stuck motor 440 is connected to an anti-stuck wheel 441, and the anti-stuck wheel 441 is located in the connection between the unloading section 412 and the loading section 411. The anti-stuck wheel 441 is ringed with partition pieces, and a space capable of accommodating the NdFeB workpiece 120 is formed between adjacent partition pieces. The anti-stuck motor 440 drives the anti-stuck wheel 441 to rotate, which can drive the NdFeB workpiece 120 to enter the unloading section 412, and can effectively prevent the NdFeB workpiece 120 from getting stuck due to overcrowding when entering the unloading section 412. This design ensures the smooth flow of workpieces, improves production efficiency, and reduces the downtime and equipment damage risks caused by material jamming.
