[0002] With the continuous progress of modern science and technology, in the face of the demand for rapid construction and development, prefabricated housing construction has become a general trend. This construction method is more standardized, mechanized and automated. ALC board is the abbreviation of autoclaved lightweight concrete. It is a porous concrete forming board formed by high-pressure steam curing. According to actual needs, ALC board can be cut into blocks, packaged, and then transported. The traditional packaging process is that the stacker stacks the ALC blocks. When the ALC blocks accumulate to a certain number of layers, they are packaged. Then the stacker places the packaged ALC blocks on the pallet and inserts the pallet through the forklift for operation. The frequent use of pallets has led to increased production costs and low production efficiency; at the same time, the traditional palletizer cannot accurately position during the movement process, which further increases the clamping time of the ALC blocks and reduces the work efficiency. How to design an ALC block stacker that does not require a pallet, can accurately position, and has high work efficiency has become an engineering problem that needs to be solved in this industry.
