[0003] In the automated production process, a basic process involved is the automatic supply of sheet materials. The existing technology generally uses a material box with an opening on the top as a sheet material storage and feeding mechanism.

During the sliding process, the two sides of the bottom plate are guided and limited by the grooves opened on the inner walls of the two limit strips to ensure the smoothness of the sliding installation and the accuracy of the position. The sliding depth is limited and fixed by the base of the support frame of the multi-piece detection mechanism arranged at the end of the installation slide groove; similarly, when the material is taken out and needs to be reloaded, the base can be pulled out horizontally from the installation slide groove in the opposite direction by the pull rod. This kind of slide-in installation method enables the movable material box assembly to complete the installation or removal efficiently and quickly, and effectively ensures the accuracy of the installation position. The movable material box assembly is installed, and in the process of taking out the materials stacked up and down one by one, the power output in the vertical direction by the lifting assembly arranged under the supporting assembly drives its lifting seat to drive the four push rods connected thereon to move up and down; in the process of taking and placing materials, the four push rods pass through the through holes opened in the supporting support plate and the bottom plate to support the supporting plate upward, and are detachably connected and fixed with the four adsorption blocks at the bottom of the supporting plate (the adsorption blocks can be magnetic blocks, which adsorb the push rods by magnetic force), and synchronously drive the supporting plate to rise successively in units of material thickness as the material taking action, so as to maintain the height position of the uppermost layer of materials in the material box space unchanged, so as to facilitate accurate material taking; when the materials in the material box space are taken out, the push rod descends, and after separating from the adsorption block, it descends downward from the through hole to the bottom of the supporting support plate, so as to avoid movement interference when sliding in or pulling out the movable material box assembly; in addition, in addition to lifting the materials to maintain the height of the uppermost layer of materials unchanged, the four push rods can also effectively realize the limiting fixation of the supporting plate and the bottom plate, so as to avoid their position displacement during the material taking process and affect the material taking accuracy.
