The invention provides a loading and unloading handling mechanical arm for a
solar cell module, and the mechanical arm provided by the invention is used for realizing the functions of loading and unloading in a
solar cell module producing process. The loading and unloading handling mechanical arm is characterized by consisting of a mechanical arm mechanism I, a horizontal motion unit II, two
vertical motion units III, a
pallet lift mechanism IV and a frame V, wherein the mechanical arm mechanism is of an aluminum
alloy frame combined structure, and is provided with a plurality of groups of sucker modules so as to realize
safe handling of
solar cell modules in different specifications; and the horizontal motion unit and the
vertical motion units adopt
servo motors as drive, and drive the mechanical arm mechanism through a synchronous cog belt and a
ball screw assembly respectively to realize accurate motion positioning in
horizontal and vertical directions, and the motion units of two directions can independently or simultaneously move. A position
servo control system is of a hierarchical control structure formed by a human-computer
interaction layer, a
motion control layer and a
servo control layer. The handling mechanical arm has the advantages of large
working space, high positioning accuracy, small motion
inertia, reliable and smooth motion and suitability for handling large-sized fragile solar
cell modules in different specifications.
