Description

Technical Field

[0002] Chip inductors, also known as power inductors, high-current inductors, and surface-mounted high-power inductors, are electromagnetic induction devices. They have characteristics such as miniaturization, high quality, high energy storage, and low resistance. Chip inductors are widely used in various electronic products. In a circuit, they mainly play a role in filtering and oscillation and are important micro magnetic components for power processing. When producing chip inductors, encapsulation is required. Encapsulation is to isolate the internal copper wire from the outside by injecting glue. For some types of inductors, a cover plate will be pasted after injecting glue to improve the sealing performance and the aesthetic appearance of the product. For example, in the utility model patent with the publication number CN210489420U, an encapsulation device for inductors is disclosed, which relates to the technical field of inductor encapsulation.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Please refer to Figures 1-10 , the present invention provides a technical solution: an automatic packaging device for patch inductors, including a base 1, a cover body 2 is fixedly arranged on the base 1, a turntable 3 is rotatably arranged in the base 1 and within the cover body 2, an inductance feeding component, a dust removal component, a dispensing component, a cover plate feeding component, and a discharging component are sequentially arranged in the cover body 2 along the rotation direction of the turntable 3. Five openings 31 are evenly arranged on the turntable 3 along its circumferential direction. The openings 31 can store inductors. The inductance feeding component, the dust removal component, the dispensing component, the cover plate feeding component, and the discharging component can be vertically aligned with the five openings 31 at the same time. By rotating the turntable 3, the inductors in the openings 31 can be transported to each process respectively. By providing five openings 31, five processes can work simultaneously. A pair of grooves 32 are opened on both sides of the bottom of the five openings 31. A pair of support plates 33 are slidably arranged in the pair of grooves 32. When the pair of support plates 33 approach each other, they can lift the inductors in the opening 31; Specifically, the inductance feeding component includes an inductance storage cylinder 41 fixedly installed on the cover body 2. The inductance storage cylinder 41 can store multiple inductors. The multiple inductors can all slide freely in the inductance storage cylinder 41. An inductance conveying mechanism is arranged below the inductance storage cylinder 41 and can convey the inductors to the opening 31, realizing automatic loading of inductors into the opening 31; Specifically, the dust removal assembly includes an air hood 52 that can move up and down within the hood 2. After the air hood 52 descends, it can be buckled above the opening 31. An exhaust port 55 corresponding vertically to the air hood 52 is provided in the base 1. The air hood 52 is connected to an air supply pipe 53. The treated clean air can enter the air hood 52 through the air supply pipe 53. After the air hood 52 descends and is buckled above the opening 31, the inductor can be dusted by spraying air, and the gas with dust can be discharged through the exhaust port 55. Specifically, the dispensing assembly includes a dispensing gun 63 that can move up and down within the hood 2. The inductor in the opening 31 is injected with glue by the descent of the dispensing gun 63. Specifically, the cover plate loading assembly includes a cover plate storage cylinder 71 fixedly installed on the hood 2. The bottom of the cover plate storage cylinder 71 extends above the turntable 3. The cover plate storage cylinder 71 can store multiple cover plates, and the multiple cover plates can slide freely therein. After the opening 31 moves directly below the cover plate storage cylinder 71, the lowermost cover plate can slide into the opening 31 by its own weight. Specifically, the unloading assembly includes a discharge port 81 provided in the base 1. When a pair of supporting plates 33 move to the discharge port 81, they can move away from each other. At this time, the inductor in the opening 31 loses support, and the inductor can be discharged along the discharge port 81 by its own weight.

[0018] As an embodiment of the present invention, the inductor conveying mechanism includes a conveying disk 43. A rotating shaft 42 is rotatably provided within the hood 2. The conveying disk 43 is fixedly installed at the bottom of the rotating shaft 42. The thickness of the conveying disk 43 is less than the thickness of the inductor. Two storage ports 44 spaced 180 degrees apart are provided on the conveying disk 43. The two storage ports 44 can be vertically aligned with the inductor storage cylinder 41 and the opening 31 respectively. A stepping motor one 45 capable of driving the rotating shaft 42 to rotate is fixedly provided on the hood 2. When the storage port 44 is vertically aligned with the inductor storage cylinder 41, the inductor in the inductor storage cylinder 41 can automatically slide into the storage port 44. The stepping motor one 45 is controlled to rotate the conveying disk 43 by 180 degrees, so as to swap the positions of the two storage ports 44. When the inductor moves above the opening 31, it can slide into the opening 31 by its own weight, thereby realizing the conveyance of the inductor. At the same time, the other storage port 44 can be automatically loaded with an inductor again. Since the thickness of the conveying disk 43 is less than the thickness of the inductor, when the conveying disk 43 rotates, the storage port 44 will not rub against the inductor in the inductor storage cylinder 41.

The telescopic end of the second telescopic rod 64 is fixedly connected to the sliding sleeve 62. The sliding sleeve 62 can be lifted or lowered by the second telescopic rod 64, thereby driving the dispensing gun 63 to rise or fall.

[0021] As an embodiment of the present invention, a fixed rod 72 is fixedly arranged above the cover body 2 and on one side of the cover storage cylinder 71. A third telescopic rod 73 is installed on one side of the fixed rod 72. The third telescopic rod 73 can adopt a cylinder or an electric push rod. The telescopic end of the third telescopic rod 73 is fixedly provided with a pressing head 74. After the third telescopic rod 73 extends, the pressing head 74 can press down the cover in the cover storage cylinder 71. The thrust generated by the third telescopic rod 73 can press the lowermost cover tightly on the inductor.

[0022] As an embodiment of the present invention, the third telescopic rod 73 can rotate around the fixed rod 72 as the axis. After rotating the third telescopic rod 73 to one side, it is convenient to load the cover into the cover storage cylinder 71.

[0023] As an embodiment of the present invention, two annular grooves 35 are formed on the upper surface of the base 1. A pin shaft 34 is fixedly arranged at the bottom of each of a pair of support plates 33. The pin shaft 34 slides in the annular groove 35. The two annular grooves 35 are provided with expansion portions 36 at positions close to the discharge port 81. When the pair of support plates 33 move to the expansion portions 36, they can move away from each other. The two annular grooves 35 can control the mutual approach or separation of the two support plates 33.

[0024] As an embodiment of the present invention, a speed reducer 91 is fixedly arranged on the cover body 2. A driving shaft 38 is fixedly arranged on the turntable 3. The driving shaft 38 passes through the cover body 2 and is connected to the power output end of the speed reducer 91. The power input end of the speed reducer 91 is connected to a second stepping motor 92. The rotation of the turntable 3 can be controlled by the second stepping motor 92, and each rotation can move the opening 31 to the next process.

[0025] As an embodiment of the present invention, a plurality of limiting ribs 37 are fixedly arranged on the side wall of the opening 31. By providing the limiting ribs 37, a gap for gas to pass through can be left between the inductor and the side wall of the opening 31, facilitating the air with dust to pass through the opening 31 during dust removal.

[0026] Working principle and usage process of the present invention: During use, multiple inductors are loaded into the inductor storage cylinder 41, multiple cover plates are loaded into the cover plate storage cylinder 71, and the air supply pipe 53 is connected to the gas supply device and the gas filtration device through a pipeline; starting the first stepping motor 45 can load inductors into the opening 31, starting the second stepping motor 92 can rotate the turntable 3, moving the opening 31 with the inductor to the dust removal assembly, starting the first telescopic rod 51 can make the bottom of the air hood 52 contact the upper surface of the turntable 3 and buckle it on the opening 31 with the inductor. Dust can be removed from the inductor by injecting clean air into the air hood 52, and the gas can be discharged through the exhaust port 55. After dust removal, control the turntable 3 to rotate again, moving the opening 31 with the inductor to the dispensing assembly, and injecting glue into the inductor by lowering the glue gun 63. After the glue injection is completed, the turntable 3 rotates again, moving the opening 31 with the inductor to the cover plate feeding assembly. When the opening 31 is vertically aligned with the cover plate storage cylinder 71, the cover plate can automatically slide into the opening 31. By starting the third telescopic rod 73, the cover plate can be pressed tightly on the inductor. After pressing for a certain time, the third telescopic rod 73 retracts, and then the turntable 3 rotates again, moving the inductor with the cover plate installed to the discharging assembly. At this time, the expansion part 36 on the annular groove 35 can make the two support plates 33 move away from each other, so that the inductor can be discharged through the discharge port 81, completing the encapsulation of the inductor; by rotating the turntable 3 again, the opening 31 after the inductor is discharged can be moved to the inductor feeding assembly for reloading, and so on in a cycle; by setting five openings 31, five processes can work simultaneously, improving the production efficiency.
