The invention discloses automotive trim full-automatic pin penetrating equipment. The automotive trim full-automatic pin penetrating equipment is formed by oppositely arranging two same systems. Each system is composed of pin grasping devices, straightening devices, pin feeding devices, pin penetrating devices and pin boxes. The pin feeding devices are arranged in the middle of a rack and are pin containing bases provided with arc-shaped grooves, the pin boxes are arranged below the pin grasping devices, the pin penetrating devices are located above the pin grasping devices, the pin grasping devices are perpendicularly arranged in a rod-shaped mode, the pin penetrating devices are horizontally arranged in a rod-shaped mode, the pin grasping devices and the pin penetrating devices are electromagnets, the pin grasping devices are arranged on a transverse guide rail of the rack in a sliding mode and can move left and right, and the pin penetrating devices are arranged on a longitudinal guide rail of the rack in a sliding mode and can move front and back. The straightening devices are arranged between the pin grasping devices and the pin feeding devices, U-shaped parts of the straightening devices are located on inlets of the arc-shaped grooves of the pin feeding devices, and the distance of an opening of each U-shaped part is the same as the width of the arc-shaped grooves. The current situation that connecting pins are completely manually assembled is changed, production efficiency is greatly improved, and labor intensity of operators is relieved.
