Measure the distance d2 to the inner edge. Here, the first reference position R1 may be arbitrarily set, but since the first panel stopper 65 is fixed, the distance from the side of the first panel stopper 65 to the first reference position R1 ( d1) is always constant. The first measurement bezel portion width W1 is obtained by subtracting d1 from the measured d2. After calculating the first measurement bezel portion width W1, it is determined whether the first measurement bezel portion width W1 is in the bezel portion reference width range Wc. The bezel portion reference width range Wc is a preset range for the bezel portion 91 of the window panel 90.

The second measurement bezel portion width W2 is obtained by subtracting d3 from the measured d4. After calculating the 2nd measuring bezel part width W2 in this way, it is determined whether the 2nd measuring bezel part width W2 exists in the bezel part reference | standard width range Wc.

The specific method of calculating the 3rd measuring bezel part width W3 is as follows. First, the bezel part 91 disposed at the edge of the third side surface 94 of the window panel 90 at the second reference position R2 spaced apart from the side surface of the second panel stopper 66 by a predetermined distance d5. Measure the distance d6 to the inner edge. Here, the second reference position R2 may be arbitrarily set. Since the second panel stopper 66 is fixed, the distance from the side of the second panel stopper 66 to the second reference position R2 ( d5) is always constant. The third measurement bezel portion width W3 is obtained by subtracting d5 from d6 measured. After the third measurement bezel portion width W3 is calculated in this way, it is determined whether the third measurement bezel portion width W3 is in the bezel portion reference width range Wc.

The specific method of calculating the 4th measuring bezel part width W4 is as follows. First, the distance d7 from the second reference position R2 to the inner edge of the bezel part 91 disposed at the edge of the fourth side 95 of the window panel 90 is measured, and the second reference position ( In R2), the distance d8 to the outer edge of the bezel part 91 disposed at the edge of the fourth side 95 of the window panel 90 is measured. The fourth measurement bezel portion width W4 is obtained by subtracting d7 from d8 measured. After the fourth measurement bezel portion width W4 is calculated, it is determined whether the fourth measurement bezel portion width W4 is in the bezel portion reference width range Wc.

Thus, after calculating the four widths of the bezel portion 91 disposed at the four side edges of the window panel 90 to determine whether they are in the bezel portion reference width range Wc, the first measurement bezel portion width W1 When the second measurement bezel portion width W2, the third measurement bezel portion width W3, and the fourth measurement bezel portion width W4 are all within the bezel portion reference width range Wc, the image display panel and the window panel ( 90) The work of attaching and afterwards is carried out continuously. On the other hand, any one or more of the first measuring bezel portion width W1, the second measuring bezel portion width W2, the third measuring bezel portion width W3, and the fourth measuring bezel portion width W4 are bezel portion reference widths. If it is out of the range Wc, the window panel 90 is separated from the panel mounting member 63 without attaching the image display panel and the window panel 90.

The first measuring bezel part width W1, the second measuring bezel part width W2, the third measuring bezel part width W3, and the fourth measuring bezel part width W4 are calculated, and these are the reference width range Wc. In determining whether or not, the measurement order or the judgment order may be changed in various ways.

As described above, the panel attaching method of the panel attaching apparatus according to the present invention accurately measures the width of the bezel part 91 even for the window panel 90 having the edges rounded and chamfered to accurately determine whether the bezel part 91 is defective. Then, by attaching only the window panel 90 in which the bezel part 91 is normally provided with the image display panel, the defective rate of the final product can be reduced and productivity can be increased.
