Description

Technical Field

[0001] The utility model relates to the technical field of PCBA board cleaning, and more specifically to a small and medium-sized PCBA board washing device. Background Art

[0002] When performing the soldering process on the surface of the PCB board, flux is required to remove oxides and reduce the surface tension of the material being soldered. However, in this process, some flux will remain on the board. In the subsequent process, these residual fluxes are easy to absorb oil, dust, and water molecules in the air, etc., posing a threat to the working stability of the PCBA board, and even affecting the stability of the entire system operation. In order to ensure the quality stability of the PCBA board and prevent the residual flux from absorbing oil and dust, the PCBA usually needs to be cleaned.

[0003] After searching, a PCBA board cleaning device disclosed in publication number CN219716816U includes a bottom plate, side vertical plates are fixedly arranged at both ends of the bottom plate, a motor table is fixedly installed on the outer side of the side vertical plate on one side, a driving motor is fixedly installed on the motor table, a transmission shaft is rotatably connected between the two side vertical plates through a bearing, one end of the transmission shaft passes through the side vertical plate on one side and is fixedly connected to the output end of the driving motor, a driving sleeve column is fixedly installed on both sides of the transmission shaft between the two side vertical plates, a driving groove is opened on the two driving sleeve columns around the circumferential surface, and the inner side walls of the two side vertical plates are fixed between the two side vertical plates and respectively located below the corresponding driving sleeve columns. A positioning support plate is fixedly installed, and both of the positioning support plates are rotatably connected with a crank arm, one end of the crank arm is fixedly provided with a pin, and the other end of the crank arm is fixedly connected with a cleaning device, and the pins of the two crank arms are respectively inserted into the driving grooves on the corresponding driving sleeves, and a plurality of rows of cleaning brushes are fixedly provided at the front end of the cleaning device, and a row of flushing holes is provided between every two rows of cleaning brushes at the front end of the cleaning device, and a high-pressure water pipe interface is fixedly provided on the cleaning device, and a top plate is fixedly installed at the upper ends of the two side plates, and a telescopic cylinder is fixedly installed at the upper end of the top plate, and the telescopic rod of the telescopic cylinder passes through the top plate and a PCBA board slot is fixedly installed between the left and right cleaning devices, and a PCBA board is inserted into the PCBA board slot.

[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, due to the use of multi-link transmission, the swing of the cleaning brush is limited. At the same time, the cleaning brush has a cleaning effect only when it swings to the nearest point close to the PCBA board, which leads to poor cleaning effect. After long-term use, the multi-links are prone to wear and tear, and are prone to rust when in contact with water. For this reason, we propose a small and medium-sized PCBA board washing device.
