[0002] A magnetic ring press-fitting device is a mechanical device used to precisely install magnetic rings onto wires, cables, or other electronic components. A magnetic ring is an electromagnetic interference suppression component widely used in electronic devices to reduce electromagnetic interference and improve electromagnetic compatibility.

[0003] However, in actual use, when the existing magnetic ring press-fitting device installs a magnetic ring, when it needs to be sleeved on a wire to reduce electromagnetic interference to the wire, when sleeving the magnetic ring on the wire, for better fixation, it is necessary to apply glue inside the magnetic ring so that it can adhere to the wire. However, the existing method of applying glue to the magnetic ring is through dotting. First, it descends into the magnetic ring, and then the glue is applied inside the magnetic ring by winding. During the production or operation process, the coordination and cooperation between positioning and applying the glue are not smooth enough, which will cause the glue to be unevenly applied inside the magnetic ring and is likely to fall off when installed on the wire. Therefore, we propose a magnetic ring press-fitting device. Summary of the Utility Model

[0033] Nozzles 5, there are multiple nozzles 5, and they are evenly distributed around the straight rod 3, and the distribution is uniform and circumferential;

[0034] A spreading plate 4, and the spreading plate 4 is arranged on the outer surface of the straight rod 3 for evenly spreading the colloid on the inner wall of the magnetic ring;

[0035] Linkage component 6 is arranged on the automatic lifting mechanism 2 and is used to spray the colloid into the interior of the magnetic ring through the nozzle 5 when the descending straight rod 3 moves downward, and at the same time, evenly apply the colloid on the inner wall of the magnetic ring by using the spreading disc 4.

[0036] The linkage component 6 includes a lifting plate 61 arranged on the outer surface of the straight rod 3. The inside of the lifting plate 61 is arranged on the outer surface of the automatic lifting mechanism 2. A rack 62 is arranged on the outer surface of the straight rod 3, and a gear 63 is arranged on the outer surface of the rack 62. The rack 62 and the gear 63 are meshed with each other. A pressing component 7 for driving the colloid into the interior of the nozzle 5 is arranged on the end face of the gear 63. When the mutually meshed rack 62 moves up and down, it can drive the gear 63 to rotate.

[0037] The pressing component 7 includes a fixing plate 71 arranged on the outer surface of the automatic lifting mechanism 2. A support frame 76 is arranged on the top of the fixing plate 71. A rotating rod 73 is movably arranged on the side surface of the support frame 76. One end of the rotating rod 73 is arranged on the end face of the gear 63. A rotating plate 72 is movably sleeved on the outer surface of the rotating rod 73. The arrangement of the support frame 76 is to support and rotate the rotating rod 73.

[0038] A linkage plate 74 is movably arranged on the side surface of the rotating plate 72. A connecting clip 75 is movably arranged on the outer surface of the linkage plate 74. An air-driven component 8 for extruding and filling the colloid is arranged at the bottom of the connecting clip 75. When the linkage plate 74 rotates, it cannot exceed the rotating rod 73, which can prevent the phenomenon of jamming.

[0039] The air-driven component 8 includes a cylinder 81 movably sleeved on the straight rod 3. The outer surface of the cylinder 81 is arranged on the side surface of the fixing plate 71. A piston ring 82 is movably arranged on the inner wall of the cylinder 81. The top end of the piston ring 82 is arranged at the bottom of the connecting clip 75. A connecting shell 84 is arranged at the bottom end of the straight rod 3. A hose 83 is arranged between the connecting shell 84 and the cylinder 81, and the connecting shell 84 and the cylinder 81 are connected and communicated through the hose 83. The outer surface of the nozzle 5 is arranged inside the connecting shell 84. The connecting shell 84 has a certain colloid storage capacity, and the arranged hose 83 has a certain deformation function.

[0040] When using this device, first place the magnetic ring on the base 1, and then drive the automatic lifting mechanism 2 to drive the lifting plate 61 to descend. The lifting plate 61 drives the straight rod 3 arranged inside to move, and the straight rod 3 drives the connecting shell 84 and the scraping disc 4 arranged at the bottom and on the outer surface to move to the inner wall of the magnetic ring. When arriving, the straight rod 3 will drive the gear 63 arranged on the outer surface to descend, and the rack 62 drives the gear 63 meshed on the outer surface to rotate. When the gear 63 rotates, it drives the rotating rod 73 to rotate, and the rotating rod 73 drives the rotating plate 72 arranged on the outer surface to rotate. The rotating plate 72 drives the linkage plate 74 arranged movably on the outer surface to move. The linkage plate 74 does not exceed the rotating rod 73, so it can drive the connecting clip 75 to move. The connecting clip 75 will drive the piston ring 82 arranged at the bottom to descend, and the colloid inside the cylinder 81 enters the inside of the connecting shell 84 through the hose 83, enters the inside of the plurality of nozzles 5 through the inside of the connecting shell 84, and then sprays onto the inner wall of the magnetic ring. And the spreading disc 4 arranged on the outer surface of the straight rod 3 will evenly scrape the colloid on the inner wall of the magnetic ring. When the automatic lifting mechanism 2 drives the lifting plate 61 to rise, it will cause the connecting clip 75 to drive the piston ring 82 to rise inside the cylinder 81, suck the colloid inside the connecting shell 84 into the inside of the cylinder 81, and at this time the straight rod 3 drives the spreading disc 4 to spread the colloid on the inner wall of the magnetic ring again.

[0041] Embodiment 2

[0042] Please refer to Figures 7-8 , this utility model provides a technical solution:

[0043] Different from Embodiment 1, a plurality of rollers 9 are movably arranged on the outer surface of the straight rod 3, and the outer surfaces of the plurality of rollers 9 are all movably arranged on the inner wall of the magnetic ring.

[0044] A circular groove 10 is opened on the outer surface of the cylinder 81 for quickly exhausting the inside of the cylinder 81.

[0045] When the spreading disc 4 moves inside the magnetic ring, the rollers 9 arranged on the outer surface of the spreading disc 4 contact the inner wall of the magnetic ring, reducing the friction. And for the circular groove 10 opened on the outer surface of the cylinder 81, when pressing the piston ring 82, gas will be sucked into the inside of the cylinder 81 through the circular groove 10, so as to push out the colloid. When pulling out the piston ring 82, through the circular groove 10, the colloid will adhere to the inside of the cylinder 81 under the action of air pressure. When the piston ring 82 moves past the circular groove 10, the air pressure inside the cylinder 81 will be balanced, so that the colloid adhering to the inside of the cylinder 81 will fall off.
