Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Reference Figure 1-Figure 6 The present invention provides a magnet slicer for processing NdFeB magnets, comprising:

[0043] Box body 1, a movable bracket and a control system 2 are installed at the bottom of the box body 1;

[0044] A slicing table 3, which is mounted on the inner bottom wall of the box body 1;

[0045] An electric turntable 4 is rotatably connected to the slicing table 3; a plurality of clamps 5 are circumferentially installed on the electric turntable 4, and the clamps 5 are used to fix the NdFeB magnet blocks;

[0046] The laser processing mechanism includes a laser cutting head 6, an X-axis moving assembly and a Y-axis moving assembly. The X-axis moving assembly is mounted on the top surface of the slicing table 3 through a lifting bracket 12, and the Y-axis moving assembly is mounted on the moving end of the X-axis moving assembly. The laser cutting head 6 is mounted on the moving end of the Y-axis moving assembly.

[0047] The laser cutting head 6 is located above the electric turntable 4, and the electric turntable 4, the X-axis moving assembly, the Y-axis moving assembly and the laser cutting head 6 are all electrically connected to the control system 2;

[0048] With such arrangement, the present invention controls the X-axis moving assembly and the Y-axis moving assembly to start through the control system 2, and drives the laser cutting head 6 to translate along the X-axis direction and the Y-axis direction, which can not only complete the slicing task of complex shapes, but also adapt to NdFeB magnet blocks of different sizes and shapes, thereby enhancing the versatility and flexibility of the equipment, realizing high-precision NdFeB magnet block slicing operations, improving the quality of the sliced ​​finished products of NdFeB magnets, and improving the qualified rate of the products;

[0049] The present invention uses a laser cutting head 6 to perform laser cutting without physical contact, which reduces the thermal effect and mechanical stress during the processing, effectively protects the internal structure and magnetic properties of the magnet, and avoids the material waste and cost increase caused by tool wear in traditional mechanical cutting. At the same time, it reduces the potential impact of debris generated by cutting on the performance of the magnet. The laser processing speed is fast, and there is no need to frequently replace the tool, which significantly shortens the production cycle and improves the overall production efficiency.

[0050] The present invention drives a plurality of clamps 5 to rotate by an electric turntable 4, and fixes a plurality of NdFeB magnet blocks by the plurality of clamps 5, so that a batch of NdFeB magnet blocks can be sliced, thereby effectively improving work efficiency.

[0051] Further optimization scheme, the center of the electric turntable 4 is rotatably connected with a central column 7, the central column 7 is fixedly connected to the top surface of the slicing table 3, an electric push plate assembly is installed on the central column 7, and the electric push plate assembly is electrically connected to the control system 2;

[0052] The fixture 5 includes a fixture bottom plate 51, on which a fixed fixture 52 and a movable fixture 53 are installed in opposite arrangement, a first slide rail 54 is installed on the fixture bottom plate 51, and the movable fixture 53 is slidably connected to the first slide rail 54; a movable push block 55 is installed on the top surface of the movable fixture 53, and the side wall of the movable push block 55 contacts the telescopic end of the electric push plate assembly, and the movable fixture 53 is connected to the fixed fixture 52 through an elastic member; a plurality of fixture bottom plates 51 are installed on the top surface of the electric turntable 4 at equal intervals in the circumferential direction;

[0053] In this arrangement, when the control system 2 receives a slicing instruction, it starts the rotating motor, and the motor drives the turntable body to rotate on the slicing table 3. This rotational movement enables the fixture 5 and the fixed magnet block installed thereon to pass under the laser cutting head 6 one by one, thereby achieving continuous slicing.

[0054] Further optimization scheme, the elastic parts include:

[0059] When it is necessary to pick up and place the magnet block, the control system 2 starts the electric push rod 9 of the electric push plate assembly to retract, and the push plate body 10 pushes the movable push block 55, thereby driving the movable clamp 53 to slide along the first slide rail 54. At this time, the reset spring 58 is in a stretched state, and the distance between the fixed clamp 52 and the movable clamp 53 increases, releasing the magnet block; after replacing the new magnet block to be processed, the control system 2 starts the electric push rod 9 of the electric push plate assembly to extend, and the push plate body 10 is separated from the movable push block 55. The movable clamp 53 is made to slide along the first slide rail 54 through the reset spring 58, and the distance between the fixed clamp 52 and the movable clamp 53 is reduced, fixing the magnet block, and facilitating slicing processing.

[0064] In a further optimized solution, the Y-axis moving assembly includes a Y-axis track 16, and both ends of the Y-axis track 16 are respectively fixedly connected to the two first sliders 15;

A second slider 19 is fixedly installed on the second chain 18, and the second slider 19 is slidably connected with the Y-axis track 16; the laser cutting head 6 is installed on the second slider 19;

[0067] In this arrangement, when the control system 2 issues an X-axis movement command, the first motor 13 is started, and drives the first slider 15 to slide on the X-axis track 11 through the second sprocket and the first chain 14; the sliding of the first slider 15 drives the Y-axis moving assembly and the laser cutting head 6 fixed thereto to move in the X-axis direction;

[0068] When the X-axis moving component reaches the predetermined position, the control system 2 issues a Y-axis moving command and the second motor 17 starts; the second motor 17 drives the second slider 19 to slide on the Y-axis track 16 through the fourth sprocket and the second chain 18, thereby realizing the movement of the laser cutting head 6 in the Y-axis direction; through the coordinated work of the X-axis and Y-axis moving components, the laser cutting head 6 can accurately slice the magnet block according to the preset path.
