Multi-layer drawer type automatic storage mechanism for circuit board

A multilayer drawer type automatic material storage mechanism for a circuit board comprises a reflow soldering furnace, a stand column, a driving assembly, a material storage assembly and a first sliding way, the front face of the stand column is fixedly connected with the driving assembly, the front face of the driving assembly is connected with the material storage assembly, and the driving assembly can drive the material storage assembly to move. A first slide way fixed with the reflow soldering furnace is arranged on the right side of the storage assembly; the first slide way is an inclined slide way, and the inclination angle of the driving assembly, the inclination angle of the storage assembly and the inclination angle of the first slide way are the same, so that after the mechanical arm places the circuit board in place, the circuit board slides into the storage assembly from the first slide way through the gravity of the circuit board. The circuit board placing device has the beneficial effects that
