Technical Field

[0001] This application relates to the field of filter packaging, and more particularly to a bare-chip-level filter packaging system. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out specific frequencies or frequencies outside of those frequencies in a power supply line, resulting in a power signal of a specific frequency, or eliminating a power signal of a specific frequency. Filter housings require encapsulation during manufacturing. Encapsulation of the power filter makes it waterproof, provides better grounding, and protects the internal components. However, filter encapsulation is typically performed in a sealed environment to achieve dust-free encapsulation.

[0003] The aforementioned technologies have at least the following technical problems: different dust particles still exist in the air within the sealed environment, which can still affect the packaging of the filter. Summary of the Invention

[0021] This application discloses a bare chip-level filter packaging system. By delivering protective gas from the protective gas storage tank 22 to the packaging box 11, the original air in the packaging box 11 is discharged through the exhaust valve 21, thereby improving the cleanliness inside the packaging box 11 and reducing the impact on the filter packaging. When it is necessary to deliver items into the packaging box 11, material feeding and air exchange can be achieved in the feeding box 32, so that the gas in the packaging box 11 is always protective gas. Moreover, since the feeding box 32 has a small volume, the amount of protective gas used can be reduced.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 A bare-chip-level filter packaging system includes a packaging device 100, a ventilation device 2, and a feeding device 3. The packaging device 100 includes a packaging box 11 and a glove-operated opening 12, the glove-operated opening 12 being disposed on the glass of the packaging box 11 and extending into the packaging box 11. The ventilation device 2 is installed on the outer wall of the packaging box 11. The feeding device 3 is installed at the inlet of the packaging box 11 and is used to transport the materials required for filter packaging into the packaging box 11.

[0024] Reference Figure 1 and Figure 2The ventilation device 2 includes an outlet valve 21, a protective gas storage tank 22, a gas supply pipe 23, and a regulating valve 24. The outlet valve 21 is installed on the sealing box 11, near its bottom; the protective gas storage tank 22 is installed on the outer wall of the sealing box 11; the gas supply pipe 23 connects the protective gas storage tank 22 and the sealing box 11; and the regulating valve 24 is installed on the gas supply pipe 23. The protective gas in the protective gas storage tank 22 is used to expel the air from the sealing box 11.

[0025] Before encapsulating the filter, the protective gas storage tank 22 is opened, allowing the protective gas in the protective gas storage tank 22 to enter the encapsulation box 11. The protective gas displaces the original air in the encapsulation box 11 and is discharged through the vent valve 21, thereby improving the cleanliness inside the encapsulation box 11 and reducing the impact on the encapsulation of the filter.

[0026] Reference Figure 2 and Figure 3 The feeding device 3 includes a support platform 31, a feeding box 32, a drive mechanism 33, a lifting mechanism 34, an air supply pipe 35, and an air outlet valve 36. The support platform 31 is horizontally fixed below the inlet of the packaging box 11; the volume of the feeding box 32 is smaller than that of the packaging box 11. The two side walls of the feeding box 32 that are perpendicular to the inlet of the packaging box 11 are open, and a left sealing plate 321 and a right sealing plate 322 are vertically slidably provided to seal the openings of the feeding box 32. The right sealing plate 322 is used to seal the inlet of the packaging box 11. A feeding plate 323 is provided inside the feeding box 32; the drive mechanism 33 is used to move the feeding plate 323 toward the inlet of the packaging box 11; the lifting mechanism 34 is used to lift the left sealing plate 321 and the right sealing plate 322; the second air supply pipe 35 is connected between the first air supply pipe 23 and the feeding box 32; the second air outlet valve 36 is installed on the feeding box 32 and is used to exhaust the air in the feeding box 32.

[0027] When it is necessary to convey items into the packaging box 11, the right sealing plate 322 of the inlet of the packaging box 11 can be sealed first, then the left sealing plate 321 can be opened, and the items can be placed on the feeding plate 323. Then the left sealing plate 321 can be lowered to seal the feeding box 32. Next, protective gas is conveyed into the feeding box 32 to expel the air inside the feeding box 32. After the air is expelled, the right sealing plate 322 is opened, and the feeding plate 323 is conveyed into the packaging box 11 by the drive mechanism 33. Therefore, during feeding, the gas in the feeding box 32 can be ventilated first, so that the gas in the packaging box 11 is always protective gas. And because the volume of the feeding box 32 is small, the amount of protective gas used can be reduced.

[0028] Reference Figure 3 and Figure 4The lifting mechanism 34 includes a U-shaped frame 341, a support plate 342, a screw 343, rotating bevel gears 344, a power mechanism 4, and a pushing mechanism 5. Two U-shaped frames 341 are provided, located above the left sealing plate 321 and the right sealing plate 322 respectively. The openings of the U-shaped frames 341 face downwards, and both ends are fixed to the top surface of the feeding box 32. The support plate 342 is fixed between the two U-shaped frames 341. Two screws 343 are provided, threadedly connected to the left sealing plate 321 and the right sealing plate 322 respectively, and passing through the top of the U-shaped frame 341. Two rotating bevel gears 344 are provided, coaxially connected to the top of the screw 343 respectively. The power mechanism 4 is used to drive the rotating bevel gears 344 on both sides to rotate.

[0029] Reference Figure 4 The power mechanism 4 includes a support base 41, a rotating rod 42, a fixed bevel gear 43, a sliding rod 44, and a power motor 45. Two support bases 41 are provided, symmetrically arranged on both sides of the support plate 342; two rotating rods 42 are provided, each rotatably mounted on one of the support bases 41 on both sides, the rotating rods 42 are horizontally arranged and perpendicular to the screw 343; a fixed bevel gear 43 is coaxially connected to the end of the rotating rod 42 near the rotating bevel gear 344, and the fixed bevel gear 43 meshes with the rotating bevel gear 344; two sliding rods 44 are provided, each slidingly mounted on one of the two rotating rods 42, and the sliding rod 44 is located at the end of the rotating rod 42 away from the fixed bevel gear 43, the sliding direction of the sliding rod 44 is consistent with the axial direction of the rotating rod 42, and a moving bevel gear 441 is coaxially connected to the end of the sliding rod 44 away from the rotating rod 42, there is space between the moving bevel gears 441 of the two sliding rods 44, and the pushing mechanism 5 is connected to the two sliding rods 44. The two sliding rods 44 can move linearly back and forth in the same direction simultaneously, making the space between the two moving bevel teeth 441 movable. This space can be simply referred to as the moving space. The power motor 45 is mounted on the support plate 342 and is located between the two moving bevel teeth 441. The output bevel teeth 451 are coaxially connected to the output shaft of the power motor 45. The output bevel teeth 451 are located in the moving space between the two moving bevel teeth 441, and the size of the output bevel teeth 451 is smaller than the size of the moving space. When the output bevel teeth 451 are placed in the moving space, the pushing mechanism 5 can make the two moving bevel teeth 441 mesh with the output bevel teeth 451 alternately. That is to say, when the moving space is driven to move by the pushing mechanism 5, the output bevel teeth 451 cannot mesh with two moving bevel teeth 441 at the same time, but can only mesh with one of the moving bevel teeth 441 at a time.

[0030] Reference Figure 4 and Figure 5A sleeve 442 is fitted onto the sliding rod 44. Rotating rings 443, which are fixedly connected to the sliding rod 44, are rotatably mounted on both sides of the sleeve 442. The rotation direction of the rotating rings 443 is the same as the rotation direction of the sliding rod 44. The pushing mechanism 5 includes a mounting cover 51, a first rack 52, a second rack 53, a rotating gear 54, a cylinder 55, and a connecting rod 56. Mounting cover 51 is located between the two sliding rods 44 and fixed to the support plate 342; rack one 52 and rack two 53 are parallel to each other and are slidably arranged on both sides of mounting cover 51, and the sliding direction of rack one 52 and rack two 53 is consistent with the sliding direction of sliding rod 44; rotating gear 54 meshes between rack one 52 and rack two 53; cylinder 55 is mounted on support plate 342 and is used to push rack one 52 to move; two connecting rods 56 are provided and are fixed to both ends of rack two 53 respectively, and the connecting rods 56 are connected between the end of rack two 53 and sleeve 442.

[0031] The cylinder 55 drives rack 52 to move, which in turn drives rotating gear 54 to rotate. Rotating gear 54 then drives rack 53 to move. When rack 53 moves, one sliding rod on one side moves towards the output bevel gear 451, while the other sliding rod 44 moves away from the output bevel gear 451. The moving bevel gear 441 on the sliding rod 44 that moves towards the output bevel gear 451 eventually meshes with the output bevel gear 451. Thus, the output bevel gear 451 can drive one of the sliding rods 44 to rotate, and the sliding rod 44 will drive the rotating rod 4... 2. When the rotating rod 42 rotates, it drives the fixed bevel gear 43, which in turn drives the rotating bevel gear 344 to rotate. The rotating bevel gear 344 then drives the screw 343 to rotate, thereby lifting the sealing plate. Due to the arrangement of the pushing mechanism 5 and the power mechanism 4, it is possible to prevent the left sealing plate 321 and the right sealing plate 322 from being opened simultaneously. If the left sealing plate 321 and the right sealing plate 322 are opened simultaneously, the protective gas in the sealing box 11 will escape directly from the feeding box 32, resulting in a large amount of leakage of the protective gas and waste.

[0032] Reference Figure 6As shown, the drive mechanism 33 includes a mounting plate 331, a lead screw 332, guide rods 333, a moving plate 334, and a drive motor 335. Two mounting plates 331 are provided, symmetrically fixed to both sides of the bottom of the feeding box 32. The lead screw 332 is rotatably disposed between the two mounting plates 331, and is perpendicular to the space between the left sealing plate 321 and the right sealing plate 322. Two guide rods 333 are provided, each located at a position relative to the lead screw 331. On both sides of the feeding box 32, guide rods 333 are fixed between two mounting plates 331; a movable plate 334 is located between the two mounting plates 331, and the movable plate 334 is threadedly connected to the lead screw 332, with the two guide rods 333 passing through the movable plate 334. A feeding plate 323 is fixed on the movable plate 334, and an exhaust valve 36 is located above the feeding plate 323. A drive motor 335 is installed at the bottom of the feeding box 32, and the output shaft of the drive motor 335 is coaxially connected to one end of the lead screw 332. The drive motor 335 drives the lead screw 332 to rotate, which in turn drives the movable plate 334 to move, which in turn drives the feeding plate 323 to move.

[0033] The functional principle of this application can be explained through the following methods:

[0034] Before encapsulating the filter, the protective gas storage tank 22 can be opened to allow the protective gas in the protective gas storage tank 22 to enter the encapsulation box 11, and the original air in the encapsulation box 11 can be discharged through the vent valve 21, thereby improving the cleanliness inside the encapsulation box 11 and reducing the impact on the encapsulation of the filter.

[0035] When it is necessary to convey items into the packaging box 11, the right sealing plate 322 of the inlet of the packaging box 11 can be sealed first, then the left sealing plate 321 can be opened, and the items can be placed on the feeding plate 323. Then the left sealing plate 321 can be lowered to seal the feeding box 32. Next, protective gas is conveyed into the feeding box 32 to expel the air inside. After the air is expelled, the right sealing plate 322 is opened, and the feeding plate 323 is conveyed into the packaging box 11 by the drive mechanism 33, so that the items can be conveyed into the packaging box 11. Therefore, during feeding, the gas in the feeding box 32 can be ventilated first, so that the gas in the packaging box 11 is always protective gas. And because the volume of the feeding box 32 is small, the amount of protective gas used can be reduced.

[0036] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
