[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Reference Figure 1 and Figure 2 As shown, an automatic chamfering device for a magnetic sheet comprises a workbench 10, an elliptical track 20 installed on the workbench 10, and a magnetic sheet chamfering device 30 installed on one side of the elliptical track 20, wherein a plurality of magnetic sheet fixing jigs 40 are arranged at intervals on the elliptical track 20, and the elliptical track 20 is used to drive each of the magnetic sheet fixing jigs 40 to move to the magnetic sheet chamfering device 30 in sequence, and the magnetic sheet chamfering device 30 is used to chamfer the magnetic sheet 70 on the magnetic sheet fixing jig 40; a dividing plate 50 is arranged in one of the arcs of the elliptical track 20, and when the magnetic sheet fixing jig 40 is located in the arc section of the elliptical track 20, the dividing plate 50 is abutted against one side of the magnetic sheet fixing jig 40.

[0027] In one of the embodiments: ten magnetic sheet fixing jigs 400 are arranged at intervals on the elliptical track 20, and the magnetic sheet fixing jigs 40 are synchronously stepped counterclockwise on the elliptical track 20 to fix the magnetic sheet 70 to be chamfered on the magnetic sheet fixing jigs 40. When the magnetic sheet fixing jigs 40 move to the magnetic sheet chamfering device 30, the magnetic sheet chamfering device 30 is activated to complete the chamfering process of the magnetic sheet 70. The magnetic disc chamfering process is efficient and continuous, saves manpower, ensures the consistency of each batch of products, improves the quality and production efficiency of the magnetic disc chamfering, and avoids the safety hazards of manual chamfering process; because the magnetic disc fixing fixture 40 is prone to displacement and instability when moving at the arc section of the elliptical track 20, through the setting of the dividing plate 50, the supporting effect of the dividing plate 50 is utilized to drive the magnetic disc fixing fixture 40 in the arc section of the elliptical track 20 to move, and the dividing plate 50 is rotated by the control of the stepping motor (not shown in the figure). The movement law of the dividing plate 50 is consistent with the transmission law of the elliptical track 20, so that the magnetic disc fixing fixture 40 can pass stably, avoiding the magnetic disc fixing fixture 40 from having too much inertia in the arc section of the elliptical track 20, causing a collision impact on the magnetic disc fixing fixture 40 being chamfered, and ensuring the continuity and stability of the magnetic disc chamfering process.

[0028] Furthermore, the elliptical track 20 includes a first linear track 201, a first curved track 202, a second linear track 203 and a second curved track 204, and the first linear track 201, the first curved track 202, the second linear track 203 and the second curved track 204 are sequentially connected to form a closed loop. The transmission track is set to an ellipse, which can reduce the area of ​​the workbench and make the device more compact as a whole; the elliptical track 20 is set to two linear tracks and two curved tracks, and the magnetic sheet chamfering device 30 is installed on one side of the linear track, which is convenient for chamfering the magnetic sheet 70.

[0029] Furthermore, the magnetic sheet chamfering device 30 comprises a driving motor 3001, a magnetic sheet chamfering processing unit 3002 and an adjusting device 3003.

The magnetic sheet chamfering device 30 mounts the driving motor 3001 on the adjusting device 3003, and can be adaptively adjusted according to the actual processing requirements of the magnetic sheet 70, thereby improving the accuracy and consistency of the magnetic sheet chamfering processing.

[0030] Further, the magnetic sheet chamfering device 30 includes a first magnetic sheet chamfering device 301 and a second magnetic sheet chamfering device 302, wherein the first magnetic sheet chamfering device 301 is arranged on one side of the first linear track 201, and the magnetic sheet chamfering processing portion 3002 of the first magnetic sheet chamfering device 301 extends onto the first linear track 201, and the second magnetic sheet chamfering device 302 is arranged on one side of the second linear track 203, and the magnetic sheet chamfering processing portion 3002 of the second magnetic sheet chamfering device 302 extends onto the second linear track 203. The first magnetic sheet chamfering device 301 is arranged on one side of the first linear track 201, and the second magnetic sheet chamfering device 302 is arranged on one side of the second linear track 203. The magnetic sheet fixing fixture 40 moves one circle on the elliptical track 20, and can complete two chamfering processes, thereby improving the production efficiency of magnetic sheet chamfering and saving manpower.

[0031] Furthermore, the first linear track 201 is provided with a stop bar 205 near the first curved track 202. By installing the stop bar 205 near the first curved track 202 on the first linear track 201, the magnetic sheet 70 to be chamfered can be loaded and unloaded in cooperation with the magnetic sheet fixing fixture 40, thereby improving the production efficiency of magnetic sheet chamfering.

[0032] Further, refer to Figure 3 As shown, the magnetic sheet fixing fixture 40 includes a base 401, a transmission lifting assembly 402, and a magnetic sheet fixing assembly 403. The magnetic sheet fixing assembly 403 is installed above the base 401 through a pillar 404. A connecting screw 405 is provided on the pillar 404. The transmission lifting assembly 402 is arranged between the base 401 and the magnetic sheet fixing assembly 403. The transmission lifting assembly 402 is centrally symmetrically arranged on both sides of the pillar 404. The transmission lifting assembly 402 is movably installed on the connecting screw 405. A transmission wheel 406 corresponding to the elliptical track 20 is installed below the base 401.

[0033] The transmission lifting assembly 402 is composed of a roller 4021, a top plate 4022, a push rod 4023 and a spring 4024. The roller 4021 is arranged corresponding to the baffle bar 205 on the first linear rail 201. The push rod 4023 is installed on the top plate 4022 and passes through the magnetic sheet fixing assembly 403. The spring 4024 is mounted on the push rod 4023 between the top plate 4022 and the magnetic sheet fixing assembly 403.

[0034] The magnetic film fixing assembly 403 includes a supporting base plate 4031, a magnetic film fixing seat 4032 arranged on the supporting base plate 4031, and a pair of magnetic film pressing arms 4033 relatively arranged at both ends of the magnetic film fixing seat 4032, the ends of the magnetic film pressing arms 4033 are movably mounted on the magnetic film fixing seat 4032, the front ends of the magnetic film pressing arms 4033 extend into the upper surface area of ​​the magnetic film fixing seat 4032, and the middle section of the magnetic film pressing arms 4033 is movably mounted on the top rod 4023 of the transmission lifting assembly 402.

[0035] When the magnetic piece fixing fixture 40 moves to the position of the stop bar 205 on the first linear track 201, the roller 4021 of the transmission lifting assembly 402 moves upward under the support of the stop bar 205, and the transmission push rod 4023 drives the magnetic piece pressure arm 4033 to open upward, and the magnetic piece 70 to be chamfered can be placed on the magnetic piece fixing seat 4032 at this time; the elliptical track 20 drives the magnetic piece fixing fixture 400 to a work station, and the roller 4021 of the transmission lifting assembly 402 leaves the stop bar 205, and the push rod 4023 resets and moves downward under the action of the spring 4024, and the transmission push rod 4023 drives the magnetic piece pressure arm 4033 to press the magnetic piece 70 on the magnetic piece fixing seat 4032 downward, completing the loading and unloading of the magnetic piece 70 to be chamfered. The magnetic sheet fixing jig 40 can move on the elliptical track 20. By utilizing the coordinated action of the transmission lifting component 402 and the magnetic sheet fixing component 403, the magnetic sheet pressing arm 4033 of the magnetic sheet fixing component 403 is driven to lift and press down, thereby achieving the fixing and release of the magnetic sheet to be chamfered. The fixing effect of the magnetic sheet 70 is good, the quality of the magnetic sheet chamfering can be improved, and the safety hazards of manual chamfering processing can be avoided.

[0036] Furthermore, five clamping positions 501 are evenly arranged on the edge of the indexing plate 50, and the clamping positions 501 can abut against the end of the connecting screw 405 of the magnetic sheet fixing fixture 40. By evenly arranging the clamping positions 501 on the edge of the indexing plate 50, the magnetic sheet fixing fixture 40 can maintain a fixed spacing and pass stably, ensuring the continuity and stability of the magnetic sheet chamfering process.

[0037] As a preferred embodiment, the dividing plates 50 are provided in two, which are respectively provided in the arcs of the first arc track 202 and the second arc track 204 of the elliptical track 20. This design can further improve the passing stability of the magnetic sheet fixing fixture 40, ensure the spacing consistency of the magnetic sheet fixing fixture 40, and improve the operation efficiency of the device.

[0038] Furthermore, the workbench 10 is mounted on a frame 60, and four feet at the bottom of the frame 60 are respectively equipped with universal wheels 601 and support feet 602, and an electric control box 603 for controlling the operation of the device is installed in the frame 60. By arranging universal wheels 601 at the bottom of the frame 60, it is convenient for the device to be moved according to actual needs; and through the support feet 602, the device as a whole can be more stable when in use, ensuring the stability of the magnetic sheet chamfering process.

[0040] Ten magnetic sheet fixing jigs 40 are arranged at intervals on the elliptical track 20, and the magnetic sheet fixing jigs 40 are synchronously stepped counterclockwise on the elliptical track 20. When the magnetic sheet fixing jig 40 moves to the position of the stop bar 205 on the first linear track 201, the loading and unloading of the magnetic sheet 70 to be chamfered is completed, and the elliptical track 20 transmits the magnetic sheet fixing jig 40 to one station. At this time, the dividing plate 50 also rotates synchronously, and the locking position 501 on the dividing plate 50 abuts against the end of the connecting screw 405 of the magnetic sheet fixing jig 40. When the magnetic sheet fixing jig 40 moves to the magnetic sheet chamfering device 30, the magnetic sheet chamfering processing part 3002 of the magnetic sheet chamfering device 30 is actuated to complete the chamfering processing of the magnetic sheet 70. The magnetic sheet fixing fixture 40 moves one circle on the elliptical track 20 to complete two chamfering processes. The chamfering processes are efficient and continuous, saving manpower, ensuring the consistency of each batch of products, improving the quality and production efficiency of the magnetic sheet chamfering, and avoiding the safety hazards of manual chamfering.
