Film pasting roller detection device for wafer film pasting

The film pasting roller detection device comprises a first V-shaped block, an outer guide rail, an inner guide rail and a second V-shaped block, the first V-shaped block is installed on the left side of the outer guide rail, the inner guide rail is installed on the right side of the outer guide rail, the inner guide rail can move in the outer guide rail in the left-right direction, and the second V-shaped block is installed on the right side of the inner guide rail. A graduated scale is installed on the front end face of the inner guide rail in the left-right direction. The device is used for detecting the levelness, the parallelism and the distance of the film pasting roller, the installation precision is ensured, the good film pasting effect is ensured, and the production efficiency can be improved; gaps between the rollers can be clearly checked through the graduated scale, and follow-up leveling is facilitated; the diameters of rollers with different diameters can be detected by arranging the V-shaped blo
