Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a structure for improving burrs on the surface of a capacitor core. Background Art

[0002] During the production process of a capacitor core of a capacitor, burrs will be generated. Especially, the burrs on the surface of the capacitor core will cause damage to the outer shell or poor AC short-circuit grounding. At present, for the burrs on the surface of the capacitor core, manual grinding is generally used, and the efficiency of manual grinding is relatively low.

[0003] The patent document with the publication number CN216399193U discloses a device for removing gold-sprayed burrs. The device for removing gold-sprayed burrs uses a burr-removing mechanism to effectively grind the burrs at both ends of the core package. The centrifugal force generated by the rotation of the grinding drum enables the edge of the core package to rub in the rectangular small holes opened in the metal drum, thereby eliminating the excess sprayed metal. However, this technical solution still needs to adopt a grinding method, which generates grinding waste and has certain limitations. Summary of the Utility Model

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0034] Refer to Figures 1 - 3, the present utility model discloses a structure for improving burrs on the surface of a capacitor core, including: a mounting plate 10, on which there are provided at least one mounting groove 30 for placing the capacitor core 20; a lifting mechanism 40, which includes a lifting driving unit 401 and a movable bracket 402, and the lifting driving unit 401 drives the movable bracket 402 to move up and down along the longitudinal direction; a compaction member 50, which is arranged on the movable bracket 402 and is located above the mounting plate 10, and the compaction member 50 moves up and down following the movable bracket 402 to compact the capacitor core 20; a burr gun 60, which blows hot air onto the capacitor core 20.

[0035] The present utility model uses the compaction member 50 and the burr gun 60 to process the capacitor core 20. The compaction member 50 compacts the capacitor core 20, and the burr gun 60 heats the capacitor core 20. As a result, the burrs on the upper surface 201 of the capacitor core 20 will curl into charred lumps, and due to the compaction of the compaction member 50, the charred lumps adhere to the upper surface 201 of the capacitor core 20, thereby improving the surface burrs of the capacitor core 20.

[0036] In an embodiment of the present utility model, the burr gun 60 is arranged on the movable bracket 402 and moves up and down following the movable bracket 402; when the compaction member 50 abuts against the upper surface 201 of the capacitor core 20, the burr gun 60 blows hot air; when the compaction member 50 separates from the upper surface 201 of the capacitor core 20, the burr gun 60 stops blowing hot air; in this way, while the compaction member 50 compacts the upper surface 201 of the capacitor core, it heats the upper surface 201 of the capacitor core 20, and the burr gun 60 blows hot air intermittently, preventing the capacitor core 20 from being burned out due to long-term heating and avoiding defective products caused by heating.

[0037] Specifically, the burr gun 60 includes a blower and a heating component, and the heating component heats the air blown by the blower to obtain hot air, and the temperature of the hot air is such that the burrs on the upper surface 201 of the capacitor core 20 can shrink.

[0038] In an embodiment of the present utility model, the compaction member 50 includes a rod body 501 and a pressing block 502. The pressing block 502 is arranged at the end of the rod body 501. The pressing block 502 is in the shape of a horn with a smaller upper part and a larger lower part, and the pressing block 502 has an inclined side surface 503; the burr gun 60 is inclinedly arranged, and the nozzle 70 of the burr gun 60 faces the inclined side surface 503 of the pressing block 502.

[0039] It should be noted that the compaction block 502 with a smaller upper part and a larger lower part has a larger compaction surface, thereby increasing the contact area between the compaction block 502 and the capacitor core 20; and the compaction block 502 has an inclined side surface 503, and the inclination angle of the inclined side surface 503 is 120° - 175°. The inclination angle of the inclined side surface 503 is adapted to the setting angle of the burr gun 60. The side surface of the compaction block 502 receives as much hot air ejected from the nozzle 70 of the burr gun 60 as possible, improving the heating efficiency of the compaction block 502. After the compaction block 502 is heated, the heat is transferred to the upper surface 201 of the capacitor core 20; of course, the hot air ejected from the burr gun 60 heats the entire capacitor core 20, that is, the burrs on the surface of the capacitor core 20 shrink to a certain extent after being heated.

[0040] In the embodiment of the present invention, the compaction member 50 is fixedly connected, detachably connected or integrally formed with the movable bracket 402; an adjusting screw 80 is provided on the movable bracket 402, and the burr gun 60 is detachably connected to the movable bracket 402 through the adjusting screw 80.

[0041] Specifically, for the burr gun 60, when the angle of the burr gun 60 needs to be adjusted, loosen the adjusting screw 80, rotate the burr gun 60 to a suitable position, and then lock the adjusting screw 80 to complete the angle adjustment of the burr gun 60.

[0042] In the embodiment of the present invention, the lifting mechanism 40 is arranged beside the mounting plate 10, and the lifting driving unit 401 is a cylinder.

[0043] In the embodiment of the present invention, a plurality of mounting grooves 30 for placing the capacitor cores 20 are provided on the mounting plate 10, and the plurality of mounting grooves 30 are arranged at intervals in the circumferential direction of the disk surface of the mounting plate 10.

[0044] In the embodiment of the present invention, the surface burr improvement structure of the capacitor core 20 further includes a rotation driving unit (not shown in the drawings), and the rotation driving unit is arranged at the central position of the bottom of the mounting plate 10 to drive the mounting plate 10 to rotate.

[0045] Specifically, each mounting groove 30 can place the capacitor core 20, and the rotation driving unit drives the mounting plate 10 to rotate so that the capacitor core 20 in the mounting groove 30 rotates to the position directly below the compaction member 50 for surface burr treatment.

[0046] In the embodiment of the present invention, the surface burr improvement structure of the capacitor core 20 further includes a conveying mechanism 90, the conveying mechanism 90 is arranged beside the mounting plate 10, and an opening is provided on the side of the mounting groove 30; when the output end of the conveying mechanism 90 is aligned with the opening of the mounting groove 30, the conveying mechanism 90 conveys the capacitor core 20 it conveys into the corresponding mounting groove 30.

[0047] Specifically, the conveying mechanism 90 can use a conveyor belt to convey the capacitor core 20.

[0048] In the embodiment of the present utility model, the rotation driving unit is a motor.

[0049] In the embodiment of the present utility model, the surface burr improvement structure of the capacitor core 20 further includes a control component (not shown in the drawings), and the lifting driving unit 401, the rotation driving unit, and the burr gun 60 are all electrically connected to the control component.

[0050] It should be noted that the opening and closing of the lifting driving unit 401, the opening and closing of the rotation driving unit, and the opening and closing of the switch of the burr gun 60 can be controlled through the control component.

[0051] In this way, the switch of the lifting driving unit 401 and the switch of the burr gun 60 can be linked. After the output end of the lifting driving unit 401 descends a predetermined stroke, the switch of the burr gun 60 is turned on. When the output end of the lifting driving unit 401 rises, the switch of the burr gun 60 is turned off, so as to achieve: when the compaction member 50 abuts against the upper surface 201 of the capacitor core 20, the burr gun 60 blows hot air; when the compaction member 50 separates from the upper surface 201 of the capacitor core 20, the burr gun 60 stops blowing hot air.

[0052] Of course, the switches of the lifting driving unit 401, the rotation driving unit, and the burr gun 60 can also be manually turned on and off to achieve: when the compaction member 50 abuts against the upper surface 201 of the capacitor core 20, the burr gun 60 blows hot air; when the compaction member 50 separates from the upper surface 201 of the capacitor core 20, the burr gun 60 stops blowing hot air.

[0053] Specifically, the rotation driving unit drives the mounting disk 10 to rotate a predetermined angle, so that the opening of the mounting groove 30 faces the output end of the conveying mechanism 90, and the conveying mechanism 90 conveys the capacitor core 20 to be processed into the corresponding mounting groove 30; the rotation driving unit continues to drive the mounting disk 10 to rotate a predetermined angle, so that the capacitor core 20 to be processed rotates with the mounting disk 10 to directly below the compaction member 50; the lifting driving unit 401 drives the movable bracket 402 to descend to a predetermined stroke. When the compaction member 50 abuts against the upper surface 201 of the capacitor core 20, the burr gun 60 blows hot air, so that the surface burr treatment of the capacitor core 20 to be processed is completed.
