A method for stacking and unstacking plates with different thicknesses

Abstract

The invention relates to a stacking and unstacking method for plates with different thicknesses, which belongs to the technical field of stamping automation production equipment for automobile body manufacturing, and solves the problem of safety risks in the existing unstacking end picker when unstacking. The method includes obtaining the change value of the height of the top of the stack and the change value of the inclination angle of the top layer of the stack after each removal of a differential thickness plate; Adjust the attitude and height position of the unstacking end picker so that the guide rod on the unstacking end picker is perpendicular to the surface of a thicker plate on the top layer of the stack. Through this method, it can ensure that the guide rod of the destacking end picker is always perpendicular to the differential thickness plate on the top layer of the stack, so as to ensure that the suction cup can better absorb each differential thickness plate, and reduce the damage of the guide rod and the suction cup during use. probability, enhance the safety of unstacking, and can stack more uneven thickness plates in the material stack, reduce the frequency of stacking changes and transport frequency of uneven thickness plates in the production process, and reduce logistics costs.

Description

technical field [0001] The invention belongs to the technical field of automatic stamping production equipment for automobile body manufacturing, and in particular relates to a method for stacking and unstacking plates with different thicknesses. Background technique [0002] With the development of the automobile industry, the requirements for lightweight and safety of automobiles are constantly increasing. When designing and manufacturing automobile bodies, automobile companies use differential thickness tailor-welded steel plates in certain parts of the body. The differential thickness tailor-welded steel plates are actually Poor thick board. [0003] Because the thickness of the two sides of the single differential thickness tailor-welded steel plate is inconsistent, after stacking, the upper surface of the stack will form a certain angle of inclination. Depending on the number of steel plates contained in the stack, the angle of inclination of the top surface of the st...
