[0002] The circuit board, also known as the PCB board, is mainly used for the centralized installation and connection of electrical components, which improves the integration of electrical components. There will be some solder traces and dust on the circuit board after the electrical components are installed, which need to be cleaned , the existing cleaning devices for printed circuit boards are mainly cleaned by brushes, which can easily lead to breakage of the connecting circuit of electrical components, so the hardness of the brushes is too high, and the board surface is not clean. Some printed circuit board cleaning devices are also equipped with drying devices to facilitate timely drying of printed circuit boards after cleaning, but the existing drying devices mainly heat the air directly, and the dust in the air is easy to adhere to On the board surface, and oxygen is easy to oxidize the circuit board at high temperature, which affects the quality of the circuit board

[0003] Existing public document, CN208450079U-a kind of printed circuit board cleaning device, discloses that its structure includes support, control cabinet, control button, power supply interface, conveyer belt, cleaning chamber, cooling hole, motor, water pump and drain outlet, the utility model A printed circuit board cleaning device is provided with a water tank, a water pipe, a filter, a water pump and a drain on the right side of the bracket, so that water can be recycled and reused, and the sewage containing impurities flowing out of the cleaning room is filtered by the filter inside the filter After the effect, impurities can be filtered out, and the water can be recycled and reused after being pumped by the water pump, which solves the disadvantage that the cleaning water cannot be recycled and causes the waste of water resources. A drying device is installed on the right side of the cleaning room, and the heating pipe is energized Heating increases the temperature and quickly dries the moisture on the cleaned circuit board, which saves waiting time, improves work efficiency, and solves the problem of low efficiency due to waiting for the circuit board to dry after cleaning. In this technology, the circuit board is simply rinsed, which is difficult to clean, and this technology only heats the air to dry the circuit board, dust is easily attached to the circuit board, and oxygen will oxidize the circuit board

[0004] Existing public document, CN209349126U-an automatic cleaning system for printed circuit boards, discloses that the transmission mechanism includes a transmission shaft, a transmission belt driven by the transmission shaft, and a metal mesh sleeved outside the transmission belt. Several printed circuits are placed on the metal mesh outside the transmission belt. plate, the first cleaning mechanism in the automatic cleaning mechanism includes a first lifting adjustment mechanism, a dust suction device located above several printed circuit boards, several upper cleaning rollers and a layer of bristles covering the surface of the upper cleaning roller, and the second cleaning mechanism includes The second lifting adjustment mechanism, the dust suction device located below the conveying mechanism, several lower cleaning rollers and a layer of bristles covering the surface of the lower cleaning rollers. The air duct, several upper cleaning rollers are driven up and down by the first lifting adjustment mechanism, and several lower cleaning rollers are driven up and down by the second lifting adjustment mechanism; the utility model provides an automatic printed circuit board cleaning system that can automatically clean the printed circuit board, In this technology, the circuit board is mainly cleaned by a brush, which can easily cause breakage of the circuit on the circuit board.
