Glass thickness deviation detector

The invention discloses a glass thickness deviation detector. A column is provided with a work panel, the work panel is provided with a control panel, the control panel is provided with a fixed plate, the fixed plate is provided with a fixed support, the fixed support is provided with a detection contact device, and one end of the detection contact device is provided with a contact head; the work panel is fixedly connected with a support frame, the bottom of the support frame is provided with a positioning device, the positioning device supports a driver, the driver is provided with a rotating shaft, the work panel is further provided with a displacement adjusting device, and the displacement adjusting device is connected with a cross bar in a sliding manner; and one end of the rotating shaft is fixedly connected with a rotating disk, and the rotating disk is provided with a clamping piece. The rotating disk rotates to obtain thickness data of the same glass in different positions, the average thickness is defined as the glass thickness, the glass thickness is compared with the standard thickness of glass, unqualified finished glass is removed, the detection efficiency is improved, and the precision of glass thickness deviation detection is improved.
