Description

Technical Field

[0001] The utility model relates to semiconductor production equipment, in particular to an automatic material basket stacking device. Background Art

[0002] After the power device chips are wire-bonded to the copper frames, they need to be reflowed in a reflow oven to ensure wire reliability. According to process requirements, during reflow, five copper frames are stacked and placed at the reflow oven entrance. At the end of each batch, batch number plates are placed at the entrance to prevent mixing. The stack of copper frames and batch number plates are then transported sequentially to the reflow oven exit via a conveyor belt. Once the stack of copper frames and batch number plates arrives, they are arranged vertically and placed into corresponding baskets by a robotic arm. Typically, several baskets are laid out on a workbench. Once full, adjacent baskets are pushed to the unloading station. This not only occupies a large area, but also often deviates when the baskets are pushed to the unloading station, impacting the robotic arm's unloading efficiency. Utility Model Content
