Reflow soldering automatic discharging production line

Abstract

A reflow soldering automatic discharging production line relates to semiconductor processing equipment. It comprises a reflow soldering discharging device, a clamping mechanical hand and a basket automatic stacking device. The reflow soldering discharging device comprises a first belt conveyor, a second belt conveyor, a straight line driving mechanism, a lifting seat and a turnover plate. Batch number plates or copper frames enter the first belt conveyor and the second belt conveyor in turn and are sent into the lifting seat. At this time, the turnover plate is in the original position and is consistent with the guide-in part. After the batch number plates or copper frames are conveyed to the position, the piston rod of the turnover cylinder is extended to turn the turnover plate upward. The batch number plates or copper frames are vertically located between the turnover plate and the vertical part. The batch number plates or copper frames are picked up by the mechanical hand of the side part and are put into the preset basket. After the batch number plates or copper frames are picked up, the turnover plate is restored to the original position and waits for the next batch number plate or copper frame to enter, thereby improving the conveying and turnover efficiency of the copper frames and the batch number plates.

Description

Technical Field

[0001] The present invention relates to semiconductor processing equipment, in particular to a reflow soldering automatic blanking production line. Background Art

[0002] After the power device chips are wire-bonded to the copper frame, they need to be reflowed in a reflow furnace to ensure the reliability of the wires. According to process requirements, during reflow, five copper frames are stacked and placed at the entrance of the reflow furnace. At the end of each batch, a batch number plate is placed at the entrance to prevent mixing of materials. The stack of copper frames and batch number plates are then transported to the exit of the reflow furnace via the reflow furnace conveyor belt. After being transported to the exit of the reflow furnace, the stack of copper frames and batch number plates need to be manually moved vertically to the bottom of a robotic arm, which then clamps the stack of copper frames and batch number plates into a material basket. This not only requires a lot of manual coordination, but also sweat during the transportation process affects the service life of the copper frames. In addition, the current method of setting up the material baskets is to lay several material baskets flat on the workbench in sequence. When the material baskets are full, the adjacent material baskets are pushed to the unloading station. This not only takes up a large area, but also easily causes confusion in the placement of the corresponding placement positions, resulting in problems such as missing materials.

At this time, the flip plate 150 is in its original position, aligned with the inlet portion 1401. After the batch number plate or copper frame is transferred to the position, the piston rod of the flip cylinder 160 extends, flipping the flip plate 150 upward. The batch number plate or copper frame is positioned vertically between the flip plate 150 and the vertical portion 1402. The batch number plate or copper frame is picked up by a side robot and placed into a pre-set material basket.
