The ejector pin through among the protective assembly withstands the panel to when solving and adsorbing, the problem of panel deformation, protective assembly has another function in addition, moves down the in-process when the sucking disc subassembly, in order to prevent to move down the volume too big and with the panel crushing, has add an inductive switch, when moving down and surpassing predetermined displacement, closes driven step motor, can effectively prevent the problem of garrulous screen.

It should be noted that, due to the particularity of the lcd panel itself, the requirement for the separating and detaching machine of the display panel packaging tray is high, and the requirement of the lcd panel can be satisfied only by specially designing the separating and detaching machine of the display panel packaging tray,of course The machine can be used for detaching the packing plate of the LCD panel, and can be applied to LCD panelsDisplay screen with low requirements Separation of other products。
