Abstract

The invention discloses a system and a method for detecting a workpiece position. The system is used for detecting the position of a workpiece in a furnace body. The bottom surface of the furnace body is formed by connecting a plurality of roller paths. The system comprises a sensor unit and a control unit, wherein the sensor unit comprises at least one sensor; the sensor is positioned outside the furnace body, connected with one of the roller paths and used for detecting an action force of the roller path on the sensor; and the control unit is connected with the sensor and used for determining the stress change of the roller path according to a detection result of the sensor and determining arrival or departure of the workpiece relative to the predetermined roller path according to the stress change. The system has the advantages of simplicity in mounting, reliable performance, convenience in maintenance and low cost.

Description

technical field [0001] The invention relates to the technical field of automated production lines, in particular to a workpiece position detection system and detection method. Background technique [0002] In order to ensure the coordinated actions of all links in the automated production line, the system needs to detect the position of the workpiece running on the roller table in real time for better automatic control. Use inclined installation for position detection, commonly used detection methods such as figure 1 and figure 2 shown. [0003] At room temperature, the signal detection of the above two installation methods is very reliable. However, industrial high-temperature heating furnaces generally have operating temperatures ranging from several hundred degrees and are in a closed state. When the workpiece is heated or tempered through the furnace body, the on-site staff cannot intuitively see the working position of the workpiece, and the system also needs real-t...
