Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of deviation correction, in particular to a high-temperature photoelectric edge alignment device. Background Art
[0002] The traditional anti-deviation system of the Teflon belt of the high-temperature bonding machine uses a micro switch to output the signal. The signal is sent by the micro switch close to the edge of the belt. The edge of the belt is always in contact with the micro switch. When the belt touches the micro switch, a signal is given to the anti-deviation mechanism, and the anti-deviation system starts to work after receiving the signal. When the belt and the micro switch are a little loose, another signal is given to the anti-deviation system, and the anti-deviation system starts to work again. This anti-deviation method is mainly summarized into two major defects: 1. The belt is running non-stop, while the micro switch is stationary. The long-term signal is given by rubbing the edge of the belt, which greatly shortens the service life of the belt; 2. The signal sent to the anti-deviation mechanism by the micro switch is too frequent, which makes the anti-deviation mechanism act frequently and the parts are easily damaged. Summary of the invention
