[0016] 2. In this invention, one row of industrial cameras can capture images of the tempered glass film to be inspected, thereby realizing the automatic detection of defects in the tempered glass film; when one or more of the industrial cameras below detect a defect in the tempered glass film, the output shaft of the servo motor a drives the rotating mounting bracket a to rotate 180° in the forward direction, thereby realizing the re-inspection of the defective tempered glass film and improving the defect detection accuracy of the tempered glass film. In addition, when the output shafts of the two servo motors b drive the rotating mounting bracket b to rotate at a certain angle, a row of industrial cameras can capture images of vertical cracks on the tempered glass film; when the output shafts of the two rows of servo motors c drive the rotating mounting bracket c to rotate at a certain angle, a row of industrial cameras can capture images of horizontal cracks on the tempered glass film, ensuring the re-inspection accuracy of the tempered glass film.
