A complex machine tool for cylindrical workpieces has a bed, a headstock assembly, at least one supporting assembly, and at least one machining assembly. The bed has three tracks being respectively a first track, a second track, a third track arranged in order. Each one of the three tracks defines a respective guiding direction, and the three guiding directions of the three tracks are mutually parallel. The headstock assembly is connected to the bed, and is located near one of two ends of the second track. The at least one supporting assembly is mounted on one of the three tracks and is used for supporting the cylindrical workpiece. The at least one machining assembly is mounted on one of the three tracks, is slidable along the track, and is located on a position at a spaced interval from the at least one supporting assembly.

The present disclosure relates to the technical field of solar cells, and more particularly to a film drawing device and method. The film drawing device includes a fixing component and a moving component. The fixing component includes a first fixing plate and a second fixing plate. The first fixing plate and the second fixing plate are opposite to each other and are configured to fix two ends of a film respectively. The moving component is connected to the first fixing, plate and/or the second fixing plate to drive the first fixing plate and/or the second fixing plate to move so as to draw the film. The film drawing device can draw the film. Finally, the entire surface of the film is smooth without folds, precise positioning is facilitated, and the problem of folds formed after bonding is solved.

A machine tool system includes a machine tool including a processor to process a workpiece with a tool, and a bed on which the processor is mounted, a transport apparatus including two, left and right, legs spaced apart from the bed to transport the workpiece and feed the workpiece to the processor or discharge the workpiece from the processor, and a plate that connects the bed to the legs and is elastically deformable. The plate is upright such that a plate surface is aligned with a front-rear direction, and a connection portion of the plate that connects with the bed and a connection portion of the plate that connects with the legs are displaced in a front-back direction.
