Variable-speed gluing device and method for module side plate

The invention discloses a variable-speed gluing device and method for a module side plate. The device comprises a scanning system, a control system and a variable-speed gluing system. The control system is electrically connected with the scanning system and the variable-speed gluing system; the scanning system scans the three-dimensional shape of the side face of the module and outputs a scanning result to the control system. The control system calculates the glue coating amount of each side plate of the module and the total glue amount needed by the module according to the scanning result, and the control system controls the glue outlet amount and the glue coating speed of the variable-speed glue coating system according to the glue coating amount and the total glue amount; and the variable-speed gluing system is adjacent to the side plate and performs variable-speed gluing on the side plate according to a control instruction of the control system. According to the invention, variable-speed gluing is carried
