The invention relates to a method for stacking thin plates, in particular to a method which can effectively improve the efficiency of stacking a substrate and a thin film into a thin plate, and can allow a plurality of stacked thin plates to cross each other to facilitate quick separation of operators.

In the manufacturing process of printed circuit boards, before the substrate is exposed, a photoresist layer and a film adhered to the surface of the photoresist layer are formed on the top and bottom surfaces of the substrate, respectively, and after the exposure, the film is peeled off to make the photoresist The layer is exposed for subsequent development and etching procedures. Before the above-mentioned substrate with a photoresist layer and the thin film are formed into a thin plate, at present, it is mainly stacked manually. After the substrate and the thin films are sequentially stacked up and down, the thin film is adhered to the upper and lower surfaces of the substrate respectively .

After adsorbing a substrate with a first suction member of a first machine, the substrate is rotated horizontally at an angle, and then laterally moved and placed above the film on the top surface of the second support base To allow the substrate and the film to completely overlap; d. After absorbing another film with the second adsorbent, move the other film laterally and place it on the top surface of the second support base, so that the substrate and the two films completely overlap. Consisting of a thin plate that has not been adhered; and e. repeating steps b to d, and the substrate and the two films are horizontally rotated by another angle, so that a plurality of thin plates are stacked on the top surface of the second support base in a manner of crossing each other .

During implementation, the first support base, the second support base, and the third support base are sequentially adjacent to each other on a frame.

During the implementation, a third detector is provided on the frame. In step b, when the third detector detects that the top position of the film is lowered, a third lifting mechanism is used to drive the third support base up to make the film The top is maintained at a fixed height.

During implementation, a first detector is provided on the frame. In step c, when the first detector detects that the top position of the substrate is lowered, a first lifting mechanism is used to drive the first support base to rise to make the substrate The top is maintained at a fixed height.
