In order to overcome the problems, some enterprises can select to process the material plates by themselves to prepare materials, namely, the whole large-size raw material plate is processed into a small-size material plate by a film sticking machine and a shearing machine so as to be required for subsequent sheet metal processing. However, in the conventional stock preparation process, the following problems are found:

firstly, the shearing of raw material plates relates to a large number of manual operations, such as feeding, receiving and the like during shearing processing. Manual operation inevitably involves safety issues, efficiency issues, and cost issues. Wherein at the pay-off link of shearing processing, owing to need the manual work to carry the flitch propelling movement to the shearing operation department of machine, in order to guarantee the shearing effect moreover, operating personnel need place the hand and hold up the flitch in the position that is close to shearing operation department, and this just has very big potential safety hazard, is not conform to the regulation of safety in production. In addition, the problem of poor feeding precision exists in manual feeding, and the surface of the raw material plate is easily scratched to influence the appearance quality.

Secondly, when shearing processing, because the size of the raw material plate is great, consequently can be because of the flexibility of material self takes place to buckle, and this just leads to the propelling movement distance when shearing at every turn and actual need's shearing size to be difficult to control accurately, easily leads to processing size not to meet the requirements.
