When the substrate 100 does not deviate, that is, the substrate 100 does not shade the photoelectric sensors at two sides, so that the photoelectric sensors at two sides can normally send signals, at this time, the controller receives the signals that the substrate 100 operates normally, and controls the power piece of the moving group at the bottom of the bracket main body 21 to work so as to drive the moving unit 22 to move forward (that is, along the first direction C) to the inlet end (rear end) of the second conveying unit 13, at this time, the lifting driver 235 is continuously started to drive the winch to work, and then the lifting frame 231 of the clamping piece 24 holding the substrate 100 is driven by the steel wire rope to move downwards until the bottom end face of the substrate 100 contacts with the second conveying unit 13.

When the substrate 100 is shifted left and right, that is, the substrate 100 will block one of the two side photosensors, so that the one side photosensor cannot normally send out a signal, and the controller receives the signal of the shift of the operation of the substrate 100. Specifically, according to which side of the substrate 100 is not detected to deviate towards which side by the photoelectric sensor at which side does not send a signal, then the driving unit 253 controls the linkage assembly 252 to drive the clamping piece 24 for clamping the substrate 100 to move left and right for adjustment until the photoelectric sensors at both sides have signals, and the operation to the second conveying unit 13 is completed.

It should be noted that, the connection portion between the moving frame and the lifting frame 231 is matched and slid by the moving guide rail, so as to realize the movement of the linkage assembly 252 relative to the lifting frame 231, and further drive the clamping member 24 to move along the length direction of the substrate 100, so as to adapt to the substrates 100 with different lengths. When the substrate 100 is clamped by the clamp 24, the substrate 100 is ensured to be positioned at the center of the lifter 231 by the left-right movement of the moving frame and the engagement of the clamp with the positioner, and the left-right direction relative to the lifter 231 is adjusted, so that the substrate 100 is ensured not to deviate in the longitudinal direction, and is ensured to be positioned at the center.

Further, the second transfer unit 13 includes an active conveyor belt and a driving member that drives the active conveyor belt so that the single-layered substrate 100 is transferred to the outlet end.
