Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core production, and more specifically, to a magnetic core surface powder cleaning device. Background Art

[0002] The magnetic core is a magnetic metal oxide composed of a mixture of various iron oxides and has a high magnetic permeability. The magnetic core is widely used in coils and transformers of various electronic equipment. Cutting and grinding operations are performed during the processing of the magnetic core, so that some debris and powder will adhere to the surface of the magnetic core.

[0003] In the production of magnetic cores, the core blanks need to be processed by a grinder to grind the top and side surfaces of the core blanks so that the size of the core meets the requirements. It is also necessary to clean the powder produced by grinding the cores, rinse off the powder and oil on the surface of the cores, and improve the cleanliness of the cores.

[0004] The debris generated after the core is polished is magnetic and will be adsorbed on the surface of the core. Using water mist spray and then a brush can make the debris fall off the surface of the core, but some of the debris will still be re-adsorbed on the surface of the core due to magnetic attraction. Therefore, repeated flushing is required, and the efficiency of core cleaning needs to be improved.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a magnetic core surface powder cleaning device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a magnetic core surface powder cleaning device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the magnetic core surface powder cleaning device comprises a pneumatic cylinder as a power source to provide linear drive, a magnetic core to be cleaned and a cleaning box as a cleaning container, the pneumatic cylinder piston rod penetrates into the cleaning box and is provided with a magnetic suction rod at the front end, the magnetic suction rod has a magnetic suction force to absorb the debris on the surface of the magnetic core, and the surface of the magnetic suction rod is evenly distributed with bristles for cleaning the debris on the surface of the magnetic core, a magnet ring is installed on the inner wall of the cleaning box, and the magnet ring is arranged at the end of the motion path of the pneumatic cylinder piston rod to scrape off the magnetic core debris absorbed and collected on the magnetic suction rod.

[0008] Preferably, the cleaning box is provided with a nozzle mounted above the magnetic core via a flushing frame for spraying water mist to flush the surface of the magnetic core.

[0009] Preferably, a hollow plate is installed on the inner wall of the cleaning box to facilitate sewage to leak down and flow to the bottom of the cleaning box. A placement rack is provided on the hollow plate, and spring rods are movably inserted at both ends of the placement rack. A clamping plate is fixed to the inner end of the spring rod for clamping the magnetic core to be cleaned.

[0010] Preferably, the height of the clamping plate is less than half of the height of the magnetic core, so as to facilitate the cleaning of the magnetic core legs and the core.

[0011] Preferably, the magnetic rods are provided in multiple groups and are distributed in a staggered manner along the magnetic core legs, the column core and the gap between the column legs and the column core, so that the magnetic rods can focus on absorbing the magnetic core debris at the grinding position of the magnetic core when performing linear reciprocating motion.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, a magnetic rod with magnetic attraction is provided, and bristles are provided on the surface of the magnetic rod. When the bristles brush off the debris with magnetic attraction, the debris can be adsorbed on the magnetic rod, thereby avoiding that part of the debris is re-adsorbed on the surface of the magnetic core due to the magnetic attraction, thereby improving the cleaning efficiency of the magnetic core.

[0014] 2. In the utility model, the magnetic suction rod is driven by a pneumatic cylinder, and a magnet ring is provided at the end of the travel path of the magnetic suction rod. After the magnetic core debris swept down is adsorbed on the magnetic suction rod, it will be scraped off by the magnet ring to avoid excessive accumulation of magnetic core debris on the magnetic core rod, affecting the cleaning efficiency of the magnetic core.

[0020] like Figure 1-3As shown, a magnetic core surface powder cleaning device comprises a pneumatic cylinder 3 as a power source providing linear drive, a magnetic core 4 to be cleaned, and a cleaning box 7 as a cleaning container, a hollow plate 11 is installed on the inner wall of the cleaning box 7, a placement rack 9 is arranged on the hollow plate 11, spring rods 8 are movably inserted at both ends of the placement rack 9, a clamping plate 10 is fixed at the inner end of the spring rod 8 for clamping and fixing the magnetic core 4 to be cleaned, the magnetic core 4 to be cleaned is placed between the clamping plates 10 as shown in the figure, and the clamping plates 10 will clamp the magnetic core 4 from both sides under the push of the spring rod 8;

[0021] The cleaning box 7 is equipped with a nozzle 6 above the magnetic core 4 through the flushing frame 5 for spraying water mist to flush the surface of the magnetic core 4. When the switch of the nozzle 6 connected to the external water source is turned on, the nozzle 6 sprays water on the surface of the magnetic core 4. Under the flushing, part of the stains will be taken away by the water flow and flow from the hollow plate 11 to the bottom of the cleaning box 7;

[0022] The piston rod of the pneumatic cylinder 3 penetrates into the cleaning box 7 and is provided with a magnetic rod 1 at the front end. The magnetic rod 1 has a magnetic attraction force to absorb the debris on the surface of the magnetic core 4, and the surface of the magnetic rod 1 is evenly distributed with bristles for cleaning the debris on the surface of the magnetic core 4. The magnetic rod 1 is provided with multiple groups, and is staggeredly distributed along the column legs, column core and the gap between the column legs and the column core of the magnetic core 4, so that the magnetic rod 1 can focus on absorbing the debris of the magnetic core 4 at the grinding position of the magnetic core 4 when performing a linear reciprocating motion;

[0023] The height of the clamping plate 10 is less than half of the height of the magnetic core 4, which is convenient for leaking the legs and core of the magnetic core 4, so that the brush on the magnetic suction rod 1 is in full contact with the legs and core of the magnetic core 4, making the cleaning more comprehensive;

[0024] Under the action of the pneumatic cylinder 3, the magnetic rod 1 extends forward, and the bristles on the surface of the magnetic rod 1 clean the surface of the magnetic core 4. A part of the stains and the debris of the magnetic core 4 will flow into the bottom of the cleaning box 7 with the water flow, and the other part of the debris of the magnetic core 4 will be attracted to the magnetic rod 1 by the magnetic attraction force of the magnetic rod 1 under the scratching of the bristles, so as to avoid being adsorbed back to the surface of the magnetic core 4. It should be noted that the magnetic attraction force of the magnetic rod 1 must be greater than that of the magnetic core 4 to achieve the above effect;

[0025] Therefore, by providing a magnetic rod 1 with magnetic attraction, and providing bristles on the surface of the magnetic rod 1, the debris with magnetic attraction can be adsorbed on the magnetic rod 1 when the bristles brush off the debris with magnetic attraction, thereby preventing some debris from being re-adsorbed on the surface of the magnetic core 4 due to the magnetic attraction, thereby improving the cleaning efficiency of the magnetic core 4;

[0026] A magnet ring 2 is installed on the inner wall of the cleaning box 7, and the magnet ring 2 is sleeved at the end of the action path of the piston rod of the pneumatic cylinder 3 to scrape off the debris of the magnetic core 4 adsorbed and collected on the magnetic rod 1;

[0027] After the magnetic core 4 rods extend forward to the bottom, they are retracted inwards under the braking of the pneumatic cylinder 3. During the recycling process, the magnetic core 4 debris on the magnetic rod 1 is adsorbed onto the magnetic circle 2 under the magnetic attraction of the magnetic circle 2. When more magnetic core 4 debris accumulates on the magnetic circle 2, it will fall into the cleaning box 7 under the action of gravity, and will not be excessively accumulated to affect the debris adsorption effect.

[0028] It is worth noting that the magnetic attraction of the magnet ring 2 is greater than that of the magnetic core 4, so that the debris of the magnetic core 4 is more easily adsorbed onto the magnet ring 2 rather than staying on the surface of the magnetic core 4. Moreover, the magnet ring 2 and the magnetic attraction rod 1 have the same magnetic poles on the side where they approach each other, so the magnetic attraction rod 1 will not be adsorbed by the magnet ring 2 when they approach each other.

[0029] The magnetic rod 1 is driven by the pneumatic cylinder 3, and a magnetic ring 2 is provided at the end of the travel path of the magnetic rod 1. After the magnetic core 4 debris swept off is adsorbed on the magnetic rod 1, it will be scraped off by the magnetic ring 2 to prevent the magnetic core 4 debris from excessively accumulating on the magnetic core 4 rod and affecting the cleaning efficiency of the magnetic core 4.

[0030] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
