Description

Technical Field

[0001] This utility model relates to the field of magnetic core technology, and in particular to a magnetic core burr cleaning device. Background Technology

[0002] In modern manufacturing, magnetic cores are important components in electronic products and power equipment, and are widely used in transformers, inductors, sensors and other fields. During the production process, burrs or protrusions often form on the surface of the magnetic core, mainly caused by processing techniques such as cutting, stamping or milling. If these burrs are not cleaned in time, they will have an adverse effect on subsequent processing, assembly and performance, and may even affect the quality and reliability of the product. Utility Model Content

[0003] The purpose of this invention is to solve the problems of incomplete cleaning and low efficiency that traditional magnetic core burr cleaning methods (such as manual grinding and mechanical polishing) usually have. This device, by introducing an automated grinding device and a precise moving system, can efficiently and evenly remove burrs from the surface of the magnetic core, thereby improving cleaning efficiency.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A magnetic core burr cleaning device includes a moving platform, a moving device at the upper end of the moving platform, a material loading device on the moving device, and a grinding device above the material loading device. The moving device includes a first rotary motor, a lead screw at the output end of the first rotary motor, a fixed bearing on the lead screw, slide rails on both sides of the fixed bearing, and a plurality of sliders on each slide rail. A base plate is fixedly connected to each slider, and positioning posts are provided at the four corners of the base plate. This device cleans burrs on the surface of the magnetic core using the grinding device, effectively removing excess metal chips or protrusions from the workpiece surface and preventing burrs from affecting subsequent processing or use. The moving device drives the lead screw through the first rotary motor to achieve precise movement of the sliders on the slide rails.

[0006] Furthermore, the material loading device includes a material loading tray with a plurality of material loading holes evenly and equidistantly arranged on the tray. A plurality of rubber sleeves are provided inside each material loading hole, and a magnetic core is provided inside each rubber sleeve. The material loading tray is movably installed and can be placed on the vibrating screen for vibrating loading of materials. After loading, it can be placed on the mobile device, which is more convenient and faster. At the same time, after the material loading tray is polished, it can be flipped over to dock with another material loading tray to complete the flipping of the material and polish the other side of the material.

[0007] Furthermore, the polishing device includes a fixed frame, with a second rotating motor mounted on one side of the upper end of the fixed frame. The output end of the second rotating motor is connected to a rotating roller, and a water spray pipe is mounted on the upper end of the rotating roller. Through the combined design of the rotating roller and the water spray pipe, the polishing device can uniformly clean the surface of the magnetic core during the polishing process, efficiently removing excess metal shavings or protrusions. The water spray pipe may spray coolant or cleaning water, which can not only effectively reduce the heat generated during the polishing process, but also clean away the shavings generated during polishing and keep the polished surface clean.

[0008] Furthermore, each of the four corners of the bottom of the material tray is provided with a positioning hole to be assembled with the positioning post for limiting the position of the material tray.

[0009] Furthermore, sandpaper is attached to the rotating roller using Velcro.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Through the linkage design of the detachable loading tray and the vibrating screen, the automatic loading and offline pre-loading functions of magnetic core materials are realized. The loading tray adopts a double-sided contact and flipping structure. With the precise positioning of the moving device, the double-sided grinding process can be completed in a single clamping.

[0012] 2. The rotating roller in the grinding device uses sandpaper attached with Velcro, which can be changed to different grits according to different processing needs to achieve a precise grinding effect. At the same time, the design of the water spray pipe can spray coolant or cleaning water to effectively reduce the heat generated during the grinding process and prevent the magnetic core surface from deforming or scratching due to high temperature.

[0013] 3. Coolant or cleaning water not only helps to cool down the surface, but also washes away the sanding debris in time, keeping the sanded surface clean and ensuring the quality and consistency of subsequent processing. Through continuous cleaning, it avoids the sandpaper from clogging or failing due to the accumulation of sanding debris, thus extending the service life of the sandpaper and reducing consumable costs.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] Combination Figure 1-4 As shown, a magnetic core burr cleaning device includes a moving platform 1, a moving device 2 at the upper end of the moving platform 1, a material loading device 3 on the moving device 2, and a grinding device 4 above the material loading device 3. The moving device 2 includes a first rotating motor 21, a lead screw 22 at the output end of the first rotating motor 21, a fixed bearing 23 on the lead screw 22, slide rails 24 on both sides of the fixed bearing 23, a plurality of sliders 25 on each slide rail 24, a base plate 26 fixedly connected to each slider 25, and positioning posts 27 at each of the four corners of the base plate 26. This device cleans burrs on the surface of the magnetic core through the grinding device, which can efficiently remove excess metal chips or protrusions from the surface of the workpiece, avoiding the impact of burrs on subsequent processing or use. The moving device drives the lead screw through the first rotating motor to achieve precise movement of the sliders on the slide rails.

[0021] The material loading device 3 includes a material loading tray 31 with a plurality of material loading holes 32 evenly and equidistantly arranged on the tray 31. A plurality of rubber sleeves 33 are provided inside each material loading hole 32, and a magnetic core 34 is provided inside each rubber sleeve 33. The material loading tray is movably installed and can be placed onto a vibrating screen for vibrating loading of materials. After loading, it can be placed on a mobile device, making it more convenient and faster. After grinding, the material loading tray can be flipped to dock with another material loading tray, completing the material flipping and allowing grinding of the other side of the material. The grinding device 4 includes a fixed frame 41, with a second rotating part on one side of the upper end of the fixed frame 41. The output end of the second rotating motor 42 is connected to a rotating roller 43. A water spray pipe 44 is provided on the upper end of the rotating roller 43. The grinding device, through the combined design of the rotating roller and the water spray pipe, can evenly clean the surface of the magnetic core during the grinding process, efficiently removing excess metal shavings or protrusions. The water spray pipe may spray coolant or cleaning water, which can not only effectively reduce the heat generated during the grinding process, but also clean away the shavings generated during grinding and keep the grinding surface clean. The four corners of the bottom of the material tray 31 are provided with positioning holes and positioning posts 27 for limiting the material tray 31. Sandpaper is attached to the rotating roller 43 with Velcro.

[0022] Working principle: The operator places the empty material tray 31 on the vibrating screen (external equipment). Vibration causes the magnetic core 34 to automatically fall into the loading hole 32. After loading, the entire material tray 31 is transferred to the base plate 26 of the moving device 2. Precise positioning is achieved through the insertion of the positioning hole and the positioning column 27. The first rotating motor 21 is started to drive the lead screw 22 to rotate, which drives the slider 25 to move horizontally along the slide rail 24, pushing the material tray 31 directly below the grinding device 4. The second rotating motor 42 is started, driving the rotating roller 43 with attached Velcro sandpaper to rotate at high speed. At the same time, the water spray pipe 44 is connected to an external water source or coolant to start spraying. The moving device 2 is connected to the external water source or coolant. Through the precise transmission of the lead screw 22, the material tray 31 is controlled to pass through the grinding area at a constant speed. The sandpaper on the rotating roller 43 continuously grinds the surface of the magnetic core 34 to remove burrs and protrusions. The water spray pipe 44 sprays liquid simultaneously to achieve a triple effect: cooling: to avoid the magnetic core overheating due to high-speed friction; cleaning: to wash away the metal shavings generated by grinding and prevent secondary adhesion; and lubrication: to improve the sandpaper grinding efficiency and surface smoothness. After grinding one side is completed, the operator flips the material tray 31 180° and connects it with another empty material tray. Then, the magnetic core is transferred by vibration so that the unprocessed side faces up. Steps 2-3 are repeated to grind the other side of the magnetic core to ensure that there are no dead corners on both sides.
