Fuel-cell assembling system capable of realizing automatic control

A related fuel-cell assembling system capable of realizing automatic control comprises a box-body clamping device which is composed of a top plate (1), a left side plate (2), a right side plate (8) and a bottom plate (7), a positioning conduction unit which is arranged in a box body and is composed of a left baffle plate (3), a right baffle plate (6), a conductive thin plate a (4) and a conductive thin plate b (5), a cylinder (9) which is arranged at the right side plate (8), an external electric-control part (10) which is composed of a solenoid valve (12) and a counterbalance valve (13), an automatic control unit (11) which is used to set a target pretightening force, output an actual pretightening force in real time, realize precise adjustment on the pretightening force by controlling the solenoid valve and the counterbalance valve, and automatically turn on and turn off an experiment apparatus according to the demand. Compared with the prior art, the system is capable of realizing rapid assembling and realizing automatic control and adjustment on the pretightening force through the external electric-control part, and solves the problems that conventional assembling mechanisms are inconvenient to use and cannot realize precise adjustment.
