PRESS PLATE MODULE, PRODUCTION LINE, AND CONTROL METHOD

A press plate module, a production line, and a control method are provided. The press plate module includes a press plate assembly and a mounting seat assembly. One of the mounting seat assembly and the press plate assembly is provided with a stop element, and the other is provided with a stop surface. The stop element is selectively extendable and retractable, and the press plate module includes a locked state and an unlocked state. In the locked state, the stop element is in an extended state and abuts against the stop surface, such that the press plate assembly is fixed with the mounting seat assembly, and the mounting seat assembly drives the press plate assembly to move, such that the press plate assembly presses against or separates from a battery. In the unlocked state, the stop element is in a retracted state and separated from the stop surface.
