Detection device and material conveying system

Abstract

The invention discloses a detection device which is used for detecting whether materials are supplied to a preset station or not. The detection device comprises a mounting plate; a lever member rotatably mounted on the mounting plate and adapted to rotate between a first position and a second position; the sensor is installed on the installation plate and used for detecting whether the lever piece is located at the second position or not. When a material is supplied to a preset station, the lever piece is pushed by the material to rotate from a first position to a second position; when no material is supplied to the preset station, the lever piece can be automatically reset to the first position under the action of gravity; when the sensor detects that the lever piece is located at the second position, it is judged that the materials are supplied to the preset station, and otherwise, it is judged that no materials are supplied to the preset station. Whether materials are supplied to the preset station or not can be directly judged according to the position of the lever piece. Therefore, an expensive visual device does not need to be used, the detection cost is reduced, and the detection efficiency can be improved.
