Description

Technical Field

[0002] In the field of power equipment and electronic component manufacturing, the iron core, as a key magnetic conductive component, has its manufacturing process directly affecting product performance and reliability.

[0003] Currently, to avoid short circuits between laminations in the iron core, an insulating coating is usually applied to the surface of the iron core. However, due to limitations in the characteristics of the coating material and the precision of the process, the coating thickness is difficult to exceed the critical value. Especially in the edge area of ​​the iron core, there are sharp burrs generated by machining, which cannot be completely covered even with an insulating layer. In the subsequent winding process, when the enameled wire comes into contact with the iron core, these burrs that are not completely covered can easily pierce the insulation layer of the enameled wire, leading to problems such as short circuits between winding turns and a decrease in insulation resistance. This seriously affects the electrical performance and service life of the product and increases the risk of equipment failure. Therefore, there is an urgent need for a device that can effectively remove burrs from the iron core to improve the processing quality of the iron core and the reliability of power equipment and electronic components.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, this embodiment provides a laser deburring device for iron cores, characterized in that it includes a base 1, a conveying assembly 5, a driving device, a fixture 3, a positioning mechanism 2, and a laser processing head 4; the conveying assembly 5 is mounted on the base 1 and is used to carry and intermittently convey the fixture 3; the driving device is mounted on the base 1 and is drivenly connected to the conveying assembly 5, and is used to drive the conveying assembly 5 to move; the fixture 3 is disposed on the conveying assembly 5, and the fixture 3 has a plurality of placement slots 301 for placing iron cores in its extending direction; the positioning mechanism 2 is mounted on the base 1, and the positioning mechanism 2 consists of two sets symmetrically arranged along the conveying direction of the conveying assembly 5, and is used to position and clamp the fixture 3 when it stops moving at the processing position; the laser processing head 4 is disposed above the base 1, and is used to perform laser removal processing on the burrs on the edge of the iron core end face placed in the placement slot 301 after the fixture 3 is positioned and clamped by the positioning mechanism 2.

[0021] Overall, the fixture 3 is placed on the conveying assembly 5, and the iron core to be processed is placed in the placement groove 301 of the fixture 3. The drive device is started to drive the conveying assembly 5 to move, and the fixture 3 is intermittently conveyed to the processing position below the laser processing head 4. When the fixture 3 moves to the processing position, the positioning mechanism 2 positions and clamps the fixture 3, which has stopped moving. The laser processing head 4 is located above the base 1 and is fixedly connected to the frame 102. It is connected to an external laser generating device. After the fixture 3 is positioned and clamped by the positioning mechanism 2, the laser processing head 4 emits a laser to remove burrs on the edge of the iron core end face placed in the placement groove 301. Laser processing has the characteristics of high precision, high speed and small heat-affected zone. It can effectively remove burrs from the iron core and will not damage the iron core body.

[0022] like Figures 1-2 As shown, in this embodiment, the conveying assembly 5 includes a first conveying wheel 501, a second conveying wheel 502, and a conveyor belt 503; the first conveying wheel 501 and the second conveying wheel 502 are rotatably mounted on the base 1, the conveyor belt 503 is connected around the first conveying wheel 501 and the second conveying wheel 502, and the fixture 3 is placed on the upper surface of the conveyor belt 503.

[0023] Specifically, the conveying assembly 5 includes a first conveying wheel 501, a second conveying wheel 502, and a conveyor belt 503; the first conveying wheel 501 and the second conveying wheel 502 are rotatably mounted on the base 1 via bearings, and the conveyor belt 503 is connected around the first conveying wheel 501 and the second conveying wheel 502 to form a closed-loop conveying structure; the fixture 3 is placed on the upper surface of the conveyor belt 503 and is conveyed under the drive of the conveyor belt 503; this conveying assembly 5 has a simple structure, stable transmission, and can reliably convey the fixture 3 to the designated position.

[0024] like Figure 2 As shown, in this embodiment, the driving device is a stepper motor 6. The output end of the stepper motor 6 is connected to the first conveyor wheel 501 and is used to drive the first conveyor wheel 501 to rotate, thereby driving the conveyor belt 503 to move and intermittently convey the fixture 3 to the processing position below the laser processing head 4.

[0025] Specifically, the driving device is a stepper motor 6, and the output end of the stepper motor 6 is connected to the first conveyor wheel 501 through a coupling. The stepper motor 6 can precisely control the rotation angle and speed, drive the first conveyor wheel 501 to rotate, and then drive the conveyor belt 503 to move, intermittently conveying the fixture 3 to the processing position below the laser processing head 4. By controlling the operation of the stepper motor 6, the fixture 3 can be accurately positioned and intermittently conveyed, ensuring the orderly progress of the deburring process of the iron core.

[0026] like Figures 2-3 As shown, in this embodiment, the positioning mechanism 2 includes a power source and a positioning component; the power source is mounted on the base 1, and the positioning component is connected to the output end of the power source; when the fixture 3 moves to the processing position, the power source drives the positioning component to move to position and clamp the fixture 3 located at the processing position.

[0027] like Figures 2-3 As shown, in this embodiment, the power source is a cylinder 201, and the positioning component is a positioning plate 202; the piston rod of the cylinder 201 is fixedly connected to the positioning plate 202.

[0028] Specifically, the positioning mechanism 2 includes a power source and a positioning component; the power source is a cylinder 201, and the positioning component is a positioning plate 202. The piston rod of the cylinder 201 is fixedly connected to the positioning plate 202. When the fixture 3 moves to the processing position, the cylinder 201 is vented, the piston rod extends, and the positioning plate 202 moves to position and clamp the fixture 3 located at the processing position. As a power source, the cylinder 201 has the advantages of fast response speed and stable thrust, and can quickly and accurately position and clamp the fixture 3.

[0029] like Figures 2-3As shown, in this embodiment, the positioning plate 202 is provided with a protrusion 203, and the side wall of the fixture 3 is provided with a groove 302 that matches the protrusion 203; when the cylinder 201 drives the positioning plate 202 to move to position and clamp the fixture 3, the protrusion 203 is embedded in the groove 302.

[0030] By setting a protrusion 203 on the positioning plate 202 and a groove 302 matching the protrusion 203 on the side wall of the fixture 3, when the cylinder 201 drives the positioning plate 202 to move to position and clamp the fixture 3, the protrusion 203 is embedded in the groove 302. This structural design makes the positioning between the positioning plate 202 and the fixture 3 more accurate and stable, avoids the fixture 3 from shifting during processing, and further improves the processing accuracy and quality of deburring the iron core.

[0031] like Figure 1 As shown, in this embodiment, the base 1 has a plurality of height-adjustable support feet 101 at its bottom.

[0032] Specifically, multiple height-adjustable support feet 101 are provided at the bottom of the base 1; by adjusting the height of the support feet 101, the device can adapt to different working sites and ensure the stability of the device during operation; at the same time, the height-adjustable support feet 101 can also perform horizontal calibration of the device to ensure the accurate relative position between the laser processing head 4 and the fixture 3, thereby improving the deburring effect of the iron core.
