Conventionally, the position of the fixed plate 200 on which the film is fixed is calculated by recognizing the shape of the display through the mold, and the position of the fixed plate 200 is moved based on this calculation Respectively. However, this method has a problem in that it takes a long time and various changes due to the input of the calculated value in accordance with the appearance of the display, and it is difficult to keep up with the development of the shape of the developed display.

The film adhering apparatus of the present invention solves this problem through the shape recognition unit 700. [ The mold is fixed and supplied to the film adhering apparatus before fixing the display to the jig and supplying it to the upper surface of the fixing plate 200.

The housing of the shape recognition unit 700 is installed on the circumferential surface of the fixing plate 200, more precisely on the circumferential surface adjacent to the film attachment means 400. The probe is installed to protrude from the housing. The probe is drawn into or drawn out of the housing according to the shape of the mold. The shape recognition unit 700 generates a sensing signal according to the degree to which the probe is drawn.

As an example, when the mold is formed in the shape of "U ", as the mold passes, the probe is drawn into the housing and is drawn out again. The shape of the mold can be recognized according to the degree of drawing and drawing. The generated detection signal is transmitted to the control unit.

The controller receives the sensing signal, recognizes the shape of the display to be manufactured through the mold, outputs a control signal corresponding to the sensing signal, and changes the position of the fixing plate 200 through the adjusting unit 300.
