Thickness detection device for material belt sheet on liquid crystal panel

The utility model relates to the technical field of detection devices, in particular to a thickness detection device for a material belt sheet on a liquid crystal panel, which comprises a detection device body and a sensor. A mounting plate and a positioning plate are fixedly connected to one side of the detection device body, a connecting rod is inserted into the top of the mounting plate, a telescopic head is arranged at the bottom of the positioning plate, the upper end of the connecting rod is fixedly connected with the telescopic head, rollers are arranged at the bottom of the connecting rod, and a pushing plate is transversely and fixedly connected to the outer wall of the connecting rod. When the connecting rods move upwards, the pushing plates push the springs to extrude together, and after stacked liquid crystal panels are processed, the pushing plates located at the bottoms rapidly move downwards through spring springs of the springs, so that the liquid crystal panels can be disassembled, and the li
