[0002] An iron core is a magnetic component made of silicon-containing steel and is mainly used in transformers and motors. The iron core is usually stacked by silicon steel sheets, and these silicon steel sheets are coated with insulating paint on the surface to improve the magnetic permeability of the magnetic circuit and reduce eddy current loss; in a transformer, the iron core is the main magnetic circuit part and together with the coil wound thereon forms an electromagnetic induction system; after the initial processing of the iron core is completed, rust may appear on the surface of the iron core due to long storage time or other factors. At this time, in order to ensure the normal operation of the iron core, rust removal processing is required for the iron core. Existing iron core rust removal devices are usually limited by the equipment. Simple equipment can only remove rust from the top and bottom surfaces of the iron core, while complex equipment or equipment with complex fixtures can remove rust from the outer peripheral surface and inner peripheral surface of the iron core, but the overall rust removal processing time is long and the processing efficiency is low. The publication number is CN116371824A, which provides a laser rust removal device and a laser rust removal method. Through the laser overall movement device, the overall horizontal movement of the laser transmission device can be realized, and at the same time, the horizontal movement can be automatically switched on and off. Through the laser transmission device, the reciprocating movement of the lower laser emitting head is realized, and laser scanning is carried out on the rust in a certain area to remove rust. At the same time, through the cooperation of the belt and the spring, the fan combination mechanism rotates reciprocally in a circle to clean the generated particulate dust and reduce the influence on laser rust removal. Through the conveyor belt device, the conveyor belt is driven to realize the horizontal movement of the rust plate, and rust plates of any size can be driven. Through the swinging fan device, the rotation of multiple fans is driven, and at the same time, the multi-fan combination structure is driven to swing around the connecting shaft.

[0047] In this embodiment, the iron core is in a circular ring structure or a structure similar to a circular ring.

[0048] This embodiment further includes a working method of the iron core laser rust removal device:

[0049] When rust removing the upper surface of the iron core: control the swing frame 3 to be horizontally arranged, then place the iron core on the rotating disk 31 so that the iron core is in a horizontal state. Then turn off the electromagnets in the multiple bases 313. When the electromagnets are powered off, the electromagnets do not work and do not attract the first magnets in the positioning columns 312. Under the action of the rebound of the return spring 314, the positioning columns 312 are pushed upward to make multiple positioning columns 312 extend out of the positioning holes 311 and support the inner peripheral surface of the iron core, thus fixing the iron core and restricting the front - back, left - right movement of the iron core; start the first servo motor 22, the second servo motor 24, and the fifth servo motor 27 respectively. The first servo motor 22 drives the first screw rod 221 to rotate to drive the sliding seat 211 and the laser head 25 to move back and forth. The second servo motor 24 drives the second screw rod 241 to rotate to drive the lifting seat 231 and the laser head 25 to move up and down. The fifth servo motor 27 drives the fifth screw rod 271 to rotate to drive the translation seat 261 and the laser head 25 to move left and right until the laser head 25 completes focusing on the upper surface of the iron core;

[0050] The first driving motor 38 drives the rotating disk 31 and the iron core to rotate. The iron core rotates at a constant speed. The laser head 25 moves to directly above the iron core and performs laser rust removal on the upper surface of the iron core. During the rust removal process, the laser head 25 moves horizontally in cooperation with the rotation speed of the iron core, and the laser projection area traverses the upper surface of the iron core to achieve rust removal on the top and bottom surfaces of the iron core.

[0051] When rust removal is performed on the outer peripheral surface of the iron core: Control the swing frame 3 to be vertically arranged so that the iron core is in a vertically placed state. Among them, start the third servo motor 12, and the third servo motor 12 drives the third screw 121 to rotate to push the advancing seat 111 to move closer to the second connecting seat 13, causing the connecting rod 15 to swing upward to push the swing frame 3 to swing upward until the swing frame 3 swings to a vertical state. Then, turn off the electromagnets in the multiple bases 313. When the electromagnets are powered off, the electromagnets do not work and do not attract the first magnet in the positioning post 312. Under the action of the rebound of the return spring 314, the positioning post 312 is pushed upward to make multiple positioning posts 312 extend out of the positioning holes 311 and support the inner peripheral surface of the iron core, thus fixing the iron core and restricting the front-back, left-right movement of the iron core; Start the first servo motor 22, the second servo motor 24, and the fifth servo motor 27 respectively. The first servo motor 22 drives the first screw 221 to rotate to drive the sliding seat 211 and the laser head 25 to move back and forth until the laser head 25 moves to the end of the sliding guide 21, so that the laser projected downward by the laser head 25 completely covers the iron core. The second servo motor 24 drives the second screw 241 to rotate to drive the lifting seat 231 and the laser head 25 to move up and down. The fifth servo motor 27 drives the fifth screw 271 to rotate to drive the translation seat 261 and the laser head 25 to move left and right until the laser head 25 completes focusing on the outer peripheral surface of the iron core and the laser projected downward by the laser head 25 can completely cover the iron core;

[0052] The iron core rotates at a constant speed, and the laser head 25 moves to directly above the iron core and performs laser rust removal on the outer peripheral surface of the iron core. During the rust removal process, the laser head 25 moves horizontally in coordination with the rotation speed of the iron core, and the laser projection area traverses the outer peripheral surface of the iron core.

[0053] When rust removal is performed on the inner peripheral surface of the iron core: Control the swing frame 3 to be inclined. Start the third servo motor 12, and the third servo motor 12 drives the third screw 121 to rotate to push the advancing seat 111 to move closer to the second connecting seat 13, causing the connecting rod 15 to swing upward to push the swing frame 3 to swing upward, making the iron core in an inclined state and making a part of the inner peripheral surface of the iron core face directly below the laser head 25, and keeping the iron core rotating at a constant speed; At the same time, make the laser head 25 reciprocate horizontally in a step-by-step manner between side A and side B to achieve laser rust removal on the inner peripheral surface of the iron core. Among them, the time interval for the single-step horizontal translation of the laser head 25 is the time for the iron core to complete N rotations, where N is an integer greater than or equal to 1, and the distance of the single-step horizontal translation is equal to the distance of the laser projection area on the inner peripheral surface of the iron core in the direction from side A to side B;

[0054] When the translation direction of the laser head 25 is from side A to side B, focusing is performed with the distance between the end point of the laser projection area in the direction of side A and the laser head 25 as the focal length; when the translation direction of the laser head 25 is from side B to side A, focusing is performed with the distance between the end point of the laser projection area in the direction of side B and the laser head 25 as the focal length. Among them, it is necessary to start the first servo motor 22 and the fifth servo motor 27 separately in advance. The first servo motor 22 drives the first screw rod 221 to rotate, so as to drive the sliding seat 211 and the laser head 25 to move back and forth. The second servo motor 24 drives the second screw rod 241 to rotate, so as to drive the lifting seat 231 and the laser head 25 to move up and down. The fifth servo motor 27 drives the fifth screw rod 271 to rotate, so as to drive the translation seat 261 and the laser head 25 to move left and right until the laser head 25 completes focusing on the end point of the inner peripheral surface of the iron core in the direction of side A. Subsequently, when rust removal is carried out, when the laser head 25 moves from side A to side B or from side B to side A, the first servo motor 22 and the second servo motor 24 are controlled to drive the laser head 25 to move back and forth horizontally and up and down vertically, so as to achieve focusing and at the same time perform laser rust removal on the inner peripheral surface of the iron core.

[0055] Among them, after rust removal of the upper surface of the iron core is completed, rust removal of the lower surface of the iron core is required. At this time, the laser head 25 is turned off, and then the electromagnets in multiple bases 313 are started. Each electromagnet is energized to attract the positioning column 312 close to the base 313, so as to pull the corresponding positioning column 312 back into the positioning hole 311, compressing the return spring 314. In this way, the iron core is released, and then the iron core is manually flipped 180°, and the iron core is placed on the turntable 31 again, so that the unrusted lower surface of the iron core is turned upwards, and the original upper surface of the iron core that has been rust-removed is turned downwards. Then, the multiple electromagnets are turned off, and the return spring 314 rebounds to push the positioning column 312 upwards, so that the multiple positioning columns 312 extend out of the positioning hole 311 and re-support the inner peripheral surface of the iron core, realizing the fixation of the iron core and restricting the front-back, left-right movement of the iron core.

[0056] Among them, when the iron core is in a vertical state or an inclined state, the second driving motor 343 is started. The second driving motor 343 drives the second driving wheel 3431 to rotate. The second driving wheel 3431 drives the second driven wheel 3421 to rotate through the second belt, so as to drive the clamping wheel 342 connected to the second driven wheel 3421 to rotate, thereby driving the iron core to rotate; when the iron core is in a horizontal state, starting the first driving motor 38 can drive the turntable 31 and the iron core to rotate.
