[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] See also Figures 1-10 The present invention provides a technical solution: an automatic packaging device for chip inductors, comprising a base 1, a cover body 2 fixedly provided on the base 1, a turntable 3 rotatably provided in the cover body 2 on the base 1, an inductor loading assembly, a dust removal assembly, a glue dispensing assembly, a cover plate loading assembly, and a blanking assembly sequentially provided in the cover body 2 along the rotation direction of the turntable 3, five openings 31 are evenly provided on the turntable 3 along its circumferential direction, the openings 31 can store inductors, the inductor loading assembly, the dust removal assembly, the glue dispensing assembly, the cover plate loading assembly, and the blanking assembly can be vertically aligned with the five openings 31 at the same time, the inductors in the openings 31 can be respectively transported to each process by rotating the turntable 3, and the five processes can be realized to work simultaneously by providing the five openings 31, a pair of grooves 32 are provided on both sides of the bottom of the five openings 31, a pair of supporting plates 33 are slidably provided in the pair of grooves 32, and the pair of supporting plates 33 can lift the inductors in the openings 31 when they are close to each other;

[0035] Specifically, the inductor loading assembly includes an inductor storage cylinder 41 fixedly mounted on the cover 2. The inductor storage cylinder 41 can store multiple inductors, and the multiple inductors can slide freely in the inductor storage cylinder 41. An inductor conveying mechanism capable of conveying the inductors to the opening 31 is provided below the inductor storage cylinder 41, thereby automatically loading the inductors into the opening 31.

[0036] Specifically, the dust removal assembly includes an air hood 52 that can move up and down within the hood body 2. After the air hood 52 is lowered, it can be buckled above the opening 31. An exhaust port 55 vertically corresponding to the air hood 52 is opened in the base 1. The air hood 52 is connected to an air supply pipe 53. Clean air after treatment can enter the air hood 52 through the air supply pipe 53. When the air hood 52 is lowered and buckled above the opening 31, the inductor can be dusted by ejecting air, and the dust-laden gas can be discharged through the exhaust port 55.

[0037] Specifically, the glue dispensing assembly includes a glue dispensing gun 63 that can move up and down in the cover 2, and the glue dispensing gun 63 is lowered to inject glue into the inductor in the opening 31;

[0038] Specifically, the cover plate loading assembly includes a cover plate storage cylinder 71 fixedly mounted on the cover body 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. When the opening 31 moves to the bottom of the cover plate storage cylinder 71, the weight of the cover plates can cause the bottom cover plate to slide into the opening 31.

[0039] Specifically, the unloading component includes a discharge port 81 opened in the base 1. When a pair of support plates 33 move to the discharge port 81, they can move away from each other.

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 inductor can be automatically loaded into the other storage opening 44 again. Because the thickness of the conveying disk 43 is smaller than the thickness of the inductor, the storage opening 44 will not be scratched by the inductor in the inductor storage tube 41 when the conveying disk 43 rotates.

The sliding sleeve 62 can be raised or lowered by the telescopic rod 2 64, thereby driving the glue gun 63 to rise or fall.

[0043] As an embodiment of the present invention, a fixing rod 72 is fixedly provided above the cover body 2 and on one side of the cover plate storage cylinder 71. A telescopic rod three 73 is installed on one side of the fixed rod 72. The telescopic rod three 73 can adopt a cylinder or an electric push rod. A pressure head 74 is fixedly provided at the telescopic end of the telescopic rod three 73. After the telescopic rod three 73 is extended, the cover plate in the cover plate storage cylinder 71 can be pressed down by the pressure head 74. The thrust generated by the telescopic rod three 73 can press the lowest cover plate onto the inductor.

[0044] As an embodiment of the present invention, the telescopic rod 3 73 can rotate with the fixed rod 72 as the axis. After the telescopic rod 3 73 is rotated to one side, it is convenient to load the cover plate into the cover plate storage tube 71.

[0045] As an embodiment of the present invention, two annular grooves 35 are provided on the upper surface of the base 1, and a pin shaft 34 is fixedly provided at the bottom of a pair of support plates 33.

The stepper motor 2 92 can control the rotation of the turntable 3, and each rotation thereof can move the opening 31 to the next process.

[0047] As an embodiment of the present invention, a plurality of limiting ribs 37 are fixedly provided on the side walls 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 walls of the opening 31, so that the air containing dust can pass through the opening 31 during dust removal.

[0048] The working principle and use process of the present invention are as follows: when in use, multiple inductors are loaded into the inductor storage tube 41, multiple cover plates are loaded into the cover plate storage tube 71, and the gas supply pipe 53 is connected to the gas supply equipment and the gas filtering device through the pipeline; starting the stepper motor 1 45 can load the inductor into the opening 31, starting the stepper motor 2 92 can make the turntable 3 rotate, so that the opening 31 equipped with the inductor moves to the dust removal component, starting the telescopic rod 1 51 can make the bottom of the air hood 52 contact with the upper surface of the turntable 3, and buckle it on the opening 31 equipped with the inductor, and the inductor can be dusted by injecting clean air into the air hood 52, and the gas can be discharged through the exhaust port 55. After the dust removal is completed, the turntable 3 is controlled to rotate again to move the opening 31 equipped with the inductor to the dispensing component, and the dispensing gun 63 is lowered to inject the inductor. After the glue injection is completed, the turntable 3 rotates again to move the opening 31 equipped with the inductor to the cover feeding assembly. When the opening 31 is vertically aligned with the cover storage cylinder 71, the cover can automatically slide into the opening 31, and the cover can be pressed tightly on the inductor by starting the telescopic rod three 73. After pressing down for a certain period of time, the telescopic rod three 73 is retracted, and then the turntable 3 rotates again to move the inductor with the cover installed to the unloading assembly. At this time, the expansion part 36 on the annular groove 35 can make the two supporting plates 33 move away from each other, so that the inductor can be discharged through the discharge port 81, completing the packaging of the inductor; by rotating the turntable 3 again, the opening 31 after the inductor is discharged can be moved to the inductor loading assembly for re-loading, and this cycle is repeated; by setting five openings 31, five processes can be realized to work simultaneously, thereby improving production efficiency.
