This utility model belongs to the field of circuit board printing technology, specifically a real-time monitoring device for circuit board printing. It includes a mounting frame with two guide rods symmetrically mounted on both sides. Sliding blocks are slidably mounted on the outer sides of each guide rod. A compression spring is fixed between one side of each sliding block and one side of the mounting frame. A storage cylinder is mounted on the top side of the sliding blocks. A rotating shaft is mounted on the output end of a
drive motor, and a
cam is mounted on the top of the rotating shaft. The storage cylinder is made of transparent material. When the
drive motor starts, the rotating shaft at its output end drives the
cam to rotate. The
cam contacts the storage cylinder, causing the storage cylinder to move the sliding blocks along the guide rods and compress the compression springs. When the cam leaves the storage cylinder, the reaction force of the compression spring causes the storage cylinder to vibrate, ensuring the ink is evenly distributed within the storage cylinder, avoiding localized voids. This allows operators to visually monitor the ink level in real-time through the transparent storage cylinder.
