[0002] The stacking machine includes inspection functions and NG elimination, and is widely used in the back-end process of the PCB industry to realize product automation, improve production efficiency and product quality, thereby reducing labor output costs. It can stack PCBA boards in a centralized manner, which is convenient for batch operations. When the automatic stacking machine is in use, it usually lifts a single PCBA board upward through the cylinder at the bottom, and then limits it through the limit mechanisms on both sides. When the cylinder is reset, the stacked PCBA boards are limited by the limit mechanism, thereby realizing the stacking operation of the PCBA boards.

[0003] During the use of the existing stacking machine, its control console is located on the upper front surface of the stacking machine, but the height of the stacking machine is usually fixed, resulting in a fixed height of the control console, which cannot adapt to operators of different heights. For this reason, we propose an automatic stacking machine for PCBA boards. Utility Model Content

[0025] Among them, the cross-sectional shapes of the fixed block 4 and the fixed slot 13 are both T-shaped, and the outer surface of the fixed block 4 and the inner side of the fixed slot 13 slide and fit with each other, so that the lifting block 12 can be stably mounted on the outer surface of the fixed block 4 through the fixed slot 13, which is easy to operate.
