AI Technical Summary
The feeding mechanism of existing pick-and-place machines is prone to unstable clamping when holding PCB substrates, resulting in inaccurate positioning.
The design employs a combination of base, clamping blocks, and transfer components. By clamping the PCB substrate on both sides of the thickness direction with clamping plates and clamping blocks, the contact area is increased. The combination of multiple clamping blocks and clamping plates ensures stable clamping.
It improves the positioning reliability of the PCB substrate in the mounting area, avoids displacement of the substrate during transportation, and enhances positioning accuracy and stability.
