Description

Technical Field

[0001] This application relates to the technical field of dust removal equipment, and in particular to a dust removal device for recycling waste circuit boards. Background Technology

[0002] Waste circuit boards refer to discarded printed circuit boards generated due to the scrapping, damage, or technological obsolescence of electronic products. During the use or stacking of waste circuit boards, dust in the air will adhere to the surface of the waste circuit boards. In order to reduce the interference of dust with the subsequent mechanical crushing effect, the surface of the waste circuit boards needs to be dusted before crushing.

[0003] Traditional dust removal methods involve manually brushing the dust off waste circuit boards, which is inefficient in removing dust from the entire circuit board and needs improvement. Utility Model Content

[0004] The purpose of this application is to provide a dust removal device for recycling waste circuit boards in order to improve the efficiency of dust removal from waste circuit boards.

[0005] The dust removal device for recycling waste circuit boards provided in this application adopts the following technical solution: it includes a dust removal box, a carrier plate is rotatably connected inside the dust removal box, a first driving component is connected to the dust removal box for driving the carrier plate to rotate, a clamping assembly is connected to the carrier plate for clamping circuit boards located on opposite sides of the carrier plate, and an air blowing assembly and a dust suction assembly are connected to the dust removal box.

[0006] By adopting the above technical solution, two waste circuit boards are placed on both sides of the carrier plate, the clamping component clamps the two circuit boards, the blowing component blows air onto one of the waste circuit boards to make the attached dust fly up, and the dust suction component sucks away the fly up dust; the first driving component drives the carrier plate to rotate so that the other waste circuit board corresponds to the blowing component, and the blowing component blows air onto the waste circuit board to achieve dust removal of the two waste circuit boards. This automatic and efficient dust removal avoids the problem of low efficiency of manual dust removal.

[0007] Optionally, the clamping assembly includes an active structure connected to the carrier plate and four clamping plates slidably connected to the carrier plate. Each pair of clamping plates forms a group, and the two groups of clamping plates are located on opposite sides of the carrier plate. The active structure is used to drive the two clamping plates in each group to slide towards each other or away from each other.

[0008] By adopting the above technical solution, the waste circuit board is placed between two clamping plates in one group. The active structure drives the two clamping plates to slide towards each other, so that the two clamping plates abut against and clamp the waste circuit board. This can easily clamp circuit boards of different sizes and keep the waste circuit board in a stable state during the dust removal process.

[0009] Optionally, the active structure includes a bidirectional lead screw rotatably connected to the carrier plate, an active member connected to the carrier plate, and two connecting blocks threadedly connected to the bidirectional lead screw. The active member is used to drive the bidirectional lead screw to rotate, and the two clamping plates in each group are respectively connected to the two connecting blocks.

[0010] By adopting the above technical solution, the active component drives the bidirectional lead screw to rotate, that is, the two connecting blocks slide towards each other or away from each other, thereby realizing the clamping plate clamping or loosening the waste circuit board.

[0011] Optionally, the driving element is a driving rod rotatably connected to the carrier plate, the driving rod is connected to a driving bevel gear, the bidirectional lead screw is connected to a driven bevel gear, and the driving bevel gear meshes with the driven bevel gear.

[0012] By adopting the above technical solution, the active rod meshes with the passive bevel gear on the bidirectional lead screw through the active bevel gear, which can drive the bidirectional lead screw to rotate. This causes the connecting block on the bidirectional lead screw to drive the two clamping plates of each group to slide towards or away from each other, thereby achieving the purpose of clamping or loosening the circuit board. This is convenient to operate and can effectively fix the circuit board.

[0013] Optionally, each of the two clamping plates in each group is provided with a support portion on the opposite side, the support portion being located at the end of the clamping plate away from the carrier plate.

[0014] By adopting the above technical solution, the support part plays a supporting role in the installation of waste circuit boards, and the operator can simultaneously install two waste circuit boards on opposite sides of the carrier board, thereby improving the efficiency of waste circuit board installation.

[0015] Optionally, cushioning pads are connected to the opposing sides of the two clamping plates in each group.

[0016] By adopting the above technical solution, the buffer pad can absorb the impact force when the waste circuit board is clamped, thus protecting the waste circuit board and preventing it from being crushed.

[0017] Optionally, the air blowing assembly includes a sliding block slidably connected inside the dust collector, a driving structure for driving the sliding block to slide, a telescopic tube connected to the sliding block, an air intake fan connected to the dust collector, and several air nozzles connected to the sliding block. The driving structure is connected to the dust collector. The sliding block is provided with an air intake channel, a main channel, and several air outlet channels. The air intake channel and several air outlet channels are all connected to the main channel. The air nozzles correspond one-to-one with the air outlet channels. The two ends of the telescopic tube are connected to the air intake fan and the air intake channel, respectively.

[0018] By adopting the above technical solution, the air intake fan delivers gas to the air intake channel of the sliding block through the telescopic pipe. The gas is blown out from the air nozzle through the main channel and the air outlet channel, which can blow dust off the waste circuit boards clamped on the carrier plate. At the same time, the drive structure can drive the sliding block to slide, so that the air nozzle can blow air on the waste circuit boards at different positions, thereby expanding the blowing range and improving the dust removal efficiency.

[0019] Optionally, the drive structure includes a rotating lead screw rotatably connected to the dust collector, a second drive member for driving the rotating lead screw to rotate, and a guide rod connected to the dust collector. The second drive member is connected to the dust collector, the sliding block is threadedly connected to the rotating lead screw, and the sliding block is slidably engaged with the guide rod.

[0020] By adopting the above technical solution, the second driving component drives the rotating screw to rotate, that is, the sliding block slides along the guide rod, so that the air nozzle can blow air on the waste circuit board at different positions, thereby expanding the blowing range and improving the dust removal efficiency.

[0021] Optionally, the dust collection assembly includes a dust collection pipe connected to the dust collection box and an exhaust fan connected to the dust collection pipe.

[0022] By adopting the above technical solution, the vacuum fan creates negative pressure inside the suction pipe, which can remove the dust blown off the surface of the waste circuit board, reducing the interference of dust with the subsequent cleaning of the waste circuit board and improving the dust removal efficiency in the waste circuit board recycling process.

[0023] Optionally, the dust collection box is provided with a dust collection chamber and a dust collection chamber, the carrier plate is located in the dust collection chamber, the dust collection assembly further includes a filter screen connected to the dust collection chamber, the dust collection box is connected with a plurality of connecting pipes, the two ends of the connecting pipes are respectively connected to the dust collection chamber and the dust collection chamber, the dust collection pipe is connected to the dust collection chamber, and the filter screen is located between the air outlet of the connecting pipe and the air inlet of the dust collection pipe.

[0024] By adopting the above technical solution, the dust in the dust removal chamber is sucked onto the filter screen through the connecting pipe, which facilitates the recycling and treatment of dust and reduces the amount of dust entering the exhaust fan, thus protecting the exhaust fan.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Place two waste circuit boards on opposite sides of a carrier plate. The clamping assembly clamps the two circuit boards together. The blowing assembly blows air onto one of the waste circuit boards, causing the attached dust to rise. The dust suction assembly then sucks up the risen dust. The first driving component drives the carrier plate to rotate, so that the other waste circuit board aligns with the blowing assembly. The blowing assembly then blows air onto the waste circuit board, achieving dust removal from both waste circuit boards. This automatic and efficient dust removal avoids the problem of low efficiency in manual dust removal.

[0027] 2. The dust in the dust removal chamber is sucked onto the filter screen through the connecting pipe, which facilitates the recycling of dust and reduces the amount of dust entering the exhaust fan, thus protecting the exhaust fan. Attached Figure Description

The clamping assembly 4 includes an active structure 41 and four clamping plates 42 slidably connected to the carrier plate 3.
