Online thickness measuring device for capacitor film production

The utility model discloses an on-line thickness measuring device for capacitor film production, which comprises two supporting plates, the tops of the two supporting plates are fixedly connected with a transmitting mounting plate, one side of the transmitting mounting plate is symmetrically and fixedly connected with connecting rods, one end of each connecting rod is fixedly connected with a receiving mounting plate, and the other end of each connecting rod is fixedly connected with a connecting rod. An adjusting mechanism and a cleaning mechanism are respectively arranged in the inner cavity of the transmitting mounting plate and the inner cavity of the receiving mounting plate, and a receiving sensor and an infrared laser are respectively arranged at the top of the adjusting mechanism. The on-line thickness measuring device for capacitive film production solves the problems that adjustment can be realized through adjustment one by one, but angle differences exist, light source receiving errors exist and de
