Problems solved by technology
During the production process of the circuit board, many processes need to be dust-removed first. Since many electronic components are integrated on the circuit board, it is more difficult to clean the dust on the circuit board.
[0003] The existing cylinder chip blowing adopts manual single piece blowing chip by hole one by one, which has low efficiency and high labor intensity
Especially for the current large-scale mechanical devices, because of the large area of the chip blowing part, and the harsh working environment of the workers, the workers are prone to fatigue, many positions are missed, and the quality of the chip blowing of the cylinder is reduced.

Embodiment 1
[0025] see figure 1 , be covered with felt 14 on the upper surface of guide plate 3, be covered with soft hair on the felt, alleviate the rigid friction of circuit board and guide plate on the one hand, on the other hand, soft hair can clean the back side of circuit board.
Embodiment 2
[0027] The difference from Embodiment 1 is that the guide plate 3 is a reticulated air-permeable plate, see figure 2 , and a second suction hood 12 is also provided on the lower left side of the guide plate 3, the second suction hood 12 passes through the dust collection box 2 through the second dust collection pipe 13 and connects the dust collection box 6, the first suction hood 4 Both are controlled by corresponding fan with the second suction hood 12, and when circuit board 8 slides along guide plate 3, the dust dust on the front and back sides of the circuit board is all sucked away by two-way suction hood, can improve dust removal efficiency.

The invention discloses a dust extraction box for a circuit board. The dust extraction box comprises a conveying belt, a dust extraction box body and a dust collection box, wherein the conveying belt and the dust collection box are both arranged at an outer side of the dust extraction box body, the conveying belt is used for transmitting the circuit board to a top end of the dust extraction box body, an opening is formed in a top part of the dust extraction box body and is used for the circuit board to pass through, a guide plate is arranged in the dust extraction box body and inclines towards a downward direction along the opening, a first air suction cover is arranged in the dust extraction box body and at a part right above the guide plate, the first air suction cover is connected with the dust collection box through a first collection pipe, an opening is formed in a right side wall of the dust extraction box body and is used for the circuit board to pass through, and a closed door is connected with the opening in a sliding way. During usage, the circuit board is transmitted to the dust extraction box body by the conveying belt and slides along the guide plate, dust is removed by the air suction covers during the sliding process, and the sucked dust is collected into the dust collection box for uniform processing. The dust extraction box is good in dust extraction effect and fast in speed.
Description
technical field [0001] The invention relates to a dust removal box for a circuit board. Background technique [0002] With the promotion of energy saving and emission reduction in the field of mechanical processing, the production of electronic products, especially the design and manufacture of electronic circuit boards, is developing towards the trend of integration and light weight. In order to achieve the above purpose, multiple electronic components (such as components including resistors, transistors, capacitors, inductors, etc.) are integrated on a circuit board. During the production process of the circuit board, many processes need to be dedusted first. Since many electronic components are integrated on the circuit board, it is more difficult to clean the dust on the circuit board. [0003] Existing cylinder chip blowing adopts manual single piece blowing chip by hole one by one, which has low efficiency and high labor intensity. Especially for the current large-sc...
