Background

At present, the stacking work of the sheets is manually carried out, and the labor intensity is high. Low stacking efficiency and the like. And manual operation sometimes causes the accumulation of thin slices, influences the continuity of a thin slice forming and thin slice stacking production line and reduces the production efficiency. The punch press is the most common hardware processing equipment. In the processing industry at the present stage, in order to ensure the surface quality of sheets discharged from a punch, workers adopt the modes of splicing and stacking one by one, stopping, replacing stacks and carrying and returning to starting for splicing in the production process. However, the splicing stacking action is single, and the stack changing and carrying are frequent. When other auxiliary work is done, the sheet can not be spliced, a large amount of downtime is wasted, the utilization rate of the punching machine is low, and the service life of the punching machine is greatly influenced by frequent startup and shutdown actions. The production efficiency of workers and equipment is low, the workers have no time to consider the product quality, the working environment and the data recording except for single splicing, and the traditional stamping material stacking mode cannot meet the current production requirement.

However, the fine processing of some small parts is a difficult problem, for example, a part of high-power radio frequency electronic components on a Printed Circuit Board (PCB) have a large heat productivity, and in order to effectively solve the heat dissipation problem, copper or aluminum heat dissipation fins with high thermal conductivity are usually embedded into the PCB in a sol bonding manner to help the radio frequency electronic components dissipate heat. Because PCB, fin are different materials, both thermal expansion coefficients are different, if bonding strength can not reach the technological requirement, very easily produce the crackle in the junction because of temperature variation during later stage use, cause the monoblock PCB board to scrap. Tests have shown that the strength of the bond between the PCB and the heat sink is related to many factors, the greatest of which is related to the side surface quality of the heat sink, and therefore places high demands on the side surface quality of the embedded heat sink. Therefore, the material sheets with large-scale technical requirements are generally processed by adopting a stamping mode, but the conventional copper or aluminum belongs to soft materials and has strong plasticity, and the punched material sheets have serious arc-shaped corner collapse edges at the periphery because the edges of the material sheets are extruded. In addition, the object is small or thin, and the like, so that the object is easy to damage when being grabbed.

Therefore, the automatic stamping system comprising the sucker grippers and the mechanical arm is needed, the mechanical arm is combined with the sucker grippers through transverse moving and lifting actions, a certain number of sheets can be automatically stacked to form a stack, the operation efficiency of the production line is improved, meanwhile, the formed sheet stack can be conveniently transferred by special equipment or personnel, the stamping automation is realized, the labor degree is reduced, and the production efficiency is improved.
