[0002] Circuit board welding is an important electronic process, in which BGA welding adopts the principle of reflow soldering.

The top of the gear 2 314 is meshed with a multi-segment rack 1 315, and the multi-segment rack 1 315 is fixed to the bottom of the box body 14. The bottom of the gear 2 314 is provided with a multi-segment rack 2 316. The gear 2 314 is meshed with the multi-segment rack 2 316 during the movement.

Bevel gear 1 310 drives rotating shaft 1 to rotate and drives visual camera 39 to rotate. Then gear 2 314 meshes with multi-segment rack 2 316 to make visual camera 39 return to its original position, so that visual camera 39 swings back and forth. Detection, swing detection can obtain the gap of electronic components from multiple angles, cooperate with the pressure of the pressing wheel 28 on the circuit board 34 to expand the gap between the components and the circuit board 34, so as to accurately identify the false welding and cold welding of the components. During the bending process of the circuit board 34, the components with false welding or cold welding will fall through the leakage port 33 and fall into the inside of the drawer 13 for collection. After the circuit board 34 is inspected, it is removed, and the circuit boards 34 with problems are separated from the circuit boards 34 without problems according to the visual data, and the circuit boards 34 with problems are manually repaired according to the visual data.
