[0027] Example:

[0028] To address the aforementioned technical problems, this embodiment provides an automatic flip-board dust removal device, comprising: a housing 1 with an internal accommodating space and an external operating platform; a flipping mechanism 2 detachably installed inside the housing 1, the flipping mechanism 2 having a carrier 21 for fixing PCB boards clamped in the middle, and a dust removal hood 3 fitted onto the flipping mechanism 2; a board feeding dust removal mechanism 4 detachably installed inside the housing 1, located on one side of the dust removal hood 3, and the board feeding dust removal mechanism 4 being connected to the flipping mechanism 2 via a first docking conveyor 41 connected to the carrier 21; a rotating dust removal mechanism 5 detachably installed inside the housing 1, located at the top of the dust removal hood 3; and a board discharge dust removal mechanism 6 detachably installed inside the housing 1, located on the other side of the dust removal hood 3, and the board discharge dust removal mechanism 6 being connected to the flipping mechanism 2 via a second docking conveyor 61 connected to the carrier 21.

[0029] The housing 1 has a layered workbench inside. The flipping mechanism 2, the board feeding dust removal mechanism 4, the rotary dust removal mechanism 5, and the board output dust removal mechanism 6 are all set on the same workbench plane. When the equipment is running, the product is placed in the PCB carrier 21 and enters the board feeding dust removal mechanism 4 through the transport line for preliminary dust removal. Then the PCB carrier 21 enters the flipping mechanism 2 and is dusted by the rotary dust removal mechanism 5. The flipping mechanism 2 will rotate at a 45-degree angle, from rotating 45 degrees to the left to rotating 45 degrees to the right. Then the PCB carrier 21 enters the board output dust removal mechanism 6 for final dust removal. After the carrier 21 flows out of the equipment, it waits for the next batch of products to repeat the above actions. The purpose of setting up the infeed dust removal mechanism 4 is to prevent external dust and other impurities from entering the housing 1 and damaging the internal components of the equipment; the purpose of setting up the outfeed dust removal mechanism 6 is to ensure the cleanliness of the product, prevent secondary pollution of the product during transportation, and improve the stability of the entire dust removal process; the rotary dust removal mechanism 5 uses a rotary nozzle 53 to spray high-pressure gas to clean the product. The rotary nozzle 53 rotates at multiple angles to clean the product, ensuring that every part of the product can be thoroughly cleaned.

[0030] Furthermore, the flipping mechanism 2 includes: a first flipping plate 22, vertically arranged, with blocking cylinders 23 installed at both ends of the first flipping plate 22, a first guide rail 24 provided on the inner side of the first flipping plate 22, one end of the carrier 21 slidably connected to the first guide rail 24, and a front rotating shaft 25 installed on the outer side of the first flipping plate 22; a second flipping plate 26, vertically arranged, with blocking cylinders 23 installed at both ends of the second flipping plate 26, a second guide rail 27 provided on the inner side of the second flipping plate 26, the other end of the carrier 21 slidably connected to the second guide rail 27, and a rear rotating shaft 28 installed on the outer side of the second flipping plate 26, and the four corners of the first flipping plate 22 and the second flipping plate 26 are connected by connecting plates 29; a wind rod 210, arranged in the same direction as the connecting plate 29, and fixed to the side of the connecting plate 29 by a fixing member 211; and two flipping brackets 212, which are respectively connected to the front rotating shaft 25 and the rear rotating shaft 28.

[0031] Four connecting plates 29 are fixed to the first flip plate 22 and the second flip plate 26 by bolts. The outer side of the first flip plate 22 is connected to the front rotating shaft 25, and the outer side of the second flip plate 26 is connected to the rear rotating shaft 28. The axes of the front rotating shaft 25 and the rear rotating shaft 28 are on the same line, and the front rotating shaft 25 and the rear rotating shaft 28 are respectively fixed on the flipping bracket 212. When the flipping mechanism 2 is working, the first flip plate 22 and the second flip plate 26 can rotate synchronously on the flipping bracket 212. When the carrier 21 enters the flipping mechanism 2 from the inlet dust removal mechanism 4, the baffle plate near the inlet dust removal mechanism 4 rises, and the carrier 21... The carrier 21 is slidably connected to the guide rails inside the first flipping plate 22 and the second flipping plate 26 in the flipping mechanism 2. The baffle of the blocking cylinder 23 descends to prevent the carrier 21 from shifting due to deflection. When the carrier 21 enters the dust removal mechanism 6 from the flipping mechanism 2, the baffle of the blocking cylinder 23 near the dust removal mechanism 6 rises, and the carrier 21 enters the dust removal mechanism 6. When the carrier 21 is being dusted in the flipping mechanism 2, the blocking cylinder 23 on one side descends, causing the first flipping plate 22 and the second flipping plate 26 to shift to the left simultaneously. The same action is repeated on the other side, causing the first flipping plate 22 and the second flipping plate 26 to shift to the right simultaneously. The air bar 210 is used to generate a high-speed airflow for surface dust removal, and works in conjunction with the flipping of the carrier 21 to clean both sides of the carrier 21.

[0032] Furthermore, the infeed dust removal mechanism 4 includes: a first fixed seat 42 group, comprising two first fixed seats 42, which are on the same plane as the flipping bracket 212, and the two first fixed seats 42 are connected by a transmission hexagonal shaft, and the first docking conveyor 41 is respectively installed on the first fixed seats 42; a first lifting door 43, with a first lifting cylinder 44 fixed above it, and the first lifting door 43 is located above the first docking conveyor 41; and two plasma generators 45, which are installed on the dust removal hood 3, one of which is located above the first docking conveyor 41 and the other is located below the first docking conveyor 41.

[0033] In this process, the first lifting cylinder 44 drives the first lifting door 43 to open, allowing the carrier 21 to enter the board dust removal mechanism 4 for initial dust removal. The first lifting door 43 is then closed to prevent external dust from entering. Next, the plasma generator 45 electrostatically adsorbs the dust and impurities on the carrier 21, thus initially removing impurities from the product. The first lifting cylinder 44 is an automated single-lever double-acting cylinder. The plasma generator 45 works in conjunction with the air bar 210. The plasma generator 45 neutralizes the static electricity on the PCB board surface, making it easier for the electrostatically adsorbed dust and impurities to detach from the PCB board surface.

[0034] Furthermore, the rotary dust removal mechanism 5 includes: a thin cylinder 51, which is fixed above the conveying dust removal hood 3 by a fixing plate 52; and a rotary nozzle 53, which is fixed at the output end of the thin cylinder 51.

[0035] The rotary dust removal mechanism 5 is located above the tilting mechanism 2, and the carrier 21 removes dust within the tilting mechanism 2. When the tilting mechanism 2 shifts, the thin cylinder 51 drives the rotary nozzle 53 to descend and remove dust. The thin cylinder 51 is a thin cylinder with a guide rod, and the rotary nozzle 53 is fixed to the output end of the thin cylinder 51 by the nozzle fixing plate 52. The rotary nozzle 53 can rotate and spray high-pressure airflow to ensure that the PCB board is thoroughly cleaned.

[0036] Furthermore, the plate-out dust removal mechanism 6 includes: a second fixed seat 62 group, comprising two second fixed seats 62, which are on the same plane as the flipping bracket 212, and the two second fixed seats 62 are connected by a transmission hexagonal shaft, and the second docking conveyor 61 is respectively installed on the second fixed seats 62; a second lifting door 63, with a second lifting cylinder 64 fixed above it, and the second lifting door 63 is located above the second docking conveyor 61; and two plasma generators 45, which are installed on the dust removal hood 3, one of which is located above the second docking conveyor 61 and the other is located below the second docking conveyor 61.

[0037] In the dust removal mechanism 6, the carrier 21 undergoes final dust removal by the plasma generator 45. The second lifting cylinder 64 drives the second lifting door 63 to open, and the second docking conveyor 61 carries the carrier 21 out of the housing 1. The second lifting cylinder 64 is also an automated single-lever double-acting cylinder. The dust cover is used to further prevent dust from contaminating the infeed dust removal mechanism, the rotary dust removal mechanism, and the outfeed dust removal mechanism, thus avoiding equipment damage and affecting work efficiency.

[0038] Furthermore, the rear rotating shaft 28 is also connected to a synchronous pulley 213, and a rotating synchronous belt 214 is fitted on the synchronous pulley 213.

[0039] The rotating synchronous belt 214 is mounted on the drive motor at one end and on the synchronous pulley 213 at the other end. When the tilting mechanism 2 deflects, the synchronous pulley 213 assists the first tilting plate 22 and the second tilting plate 26 in tilting together. The pitch of the synchronous pulley is 5mm.

[0040] Furthermore, the dust collection device 7 is located next to the housing 1 and is connected to the housing 1; the cartridge dust collector 8 is installed below the tilting mechanism 2 and is connected to the dust collection device 7.

[0041] Among them, the cartridge dust collector 8 is used to collect dust particles and then discharge them to the dust collection device 7, so as to avoid the dust in the housing 1 from affecting the subsequent dust removal work.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
