The invention discloses an infrared ray deviation preventing and correcting device used for processing a box body plate of a television transmitter. The infrared ray deviation preventing and correcting device comprises a base, a rolling roller shaft and a sliding rod. A first groove and a second groove are formed in the positions, close to the two ends, of the top of the base correspondingly. A first correcting screw rod and a second correcting screw rod are installed in the first groove and the second groove correspondingly. A first drive motor and a second drive motor are installed at the positions, corresponding to the first groove and the second groove, of one side of the base through bolts correspondingly. An output shaft of the first drive motor and an output shaft of the second drive motor are fixedly connected with the first correcting screw rod and the second correcting screw rod correspondingly. A first supporting plate and a second supporting plate are installed on the portions, above the base, of the first correcting screw rod and the second correcting screw rod correspondingly. Installing bases are installed on the inner side of the first supporting plate and the innerside of the second supporting plate correspondingly. According to the infrared ray deviation preventing and correcting device, a guide roller is installed on the base, a certain effect of guiding thebox body plate in the conveying process is achieved, and the situation of severe deviation is avoided.
