The invention discloses a damping transport device for solar photovoltaic substrates and relates to the technical field of solar photovoltaic equipment. The damping transport device comprises a box body; fixed outer frames which are symmetric mutually are fixedly connected to the two sides of the bottom of the inner wall of the box body; the inner walls of the fixed outer frames are slidably connected with first sliding blocks; the tops of the first sliding blocks are fixedly connected with sliding rods, and the sliding rods penetrate through the tops of the inner walls of the fixed outer frames and extend out of the fixed outer frames; first springs are arranged between the tops of the first sliding blocks and the tops of the inner walls of the fixed outer frames and located on the surfaces of the sliding rods; and the middles of the two sides of the inner wall of the box body are fixedly connected with limiting plates which are symmetric mutually. According to the damping transport device for the solar photovoltaic substrates, the current problem that a large quantity of economic losses are caused by the fact that the solar photovoltaic substrates are vibrated in the transport process and consequently battery pieces are damaged is solved, the damage probability of the substrates in the transport process is decreased greatly, transport safety and stability are improved, and accordingly the transport efficiency is improved.
