Embodiment Construction
[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Such as figure 1 As shown, the automatic centering detection method of the strip based on infrared light depends on the structure of the detection device, including sensor group A1 and sensor group B2 respectively arranged along the two side edges of the strip direction, sensor group A1 and sensor group B2 Both include a transmitting end and a receiving end. Each group of transmitting ends is equipped with multiple sets of infrared emitting tubes, and each group of receiving ends is equipped with multiple sets of infrared receiving tubes. The function of the transmitting end is to control the scanning infrared emitting tubes to emit light in sequence. Scanning the control signal, the sensor group A1 and the sensor group B2 are jointly connected to the controller 3, the controller 3 is connected to the deviation correction actuator 4 on...

A belt material automatic centering detection method based on infrared light specifically includes the following steps that firstly, a belt material moves between infrared transmitting pipes and infrared receiving pipes, and a controller receives state change information of the infrared receiving pipes; secondly, a mathematical model of photoelectric correlated cells is set up according to the positions of the infrared transmitting pipes and the infrared receiving pipes, a space rectangular coordinate system is established, the areas where the edge positions of the belt material are located are determined, and position information of the edges of the belt material is calculated; and thirdly, whether the belt material deviates from the transmission center line or not is judged, if the beltmaterial deviates from the transmission center line, the position deviation amount is sent to a deviation rectification execution mechanism, deviation rectification is conducted on the belt material,and therefore centering is achieved. The belt material automatic centering detection method solves the problems that in the prior art, because detection is conducted according to the principle of parallel light, the detection precision is not high enough and the detection range is limited.
Description
technical field [0001] The invention belongs to the technical field of strip material automatic detection, and relates to a strip material automatic centering detection method based on infrared light. Background technique [0002] With the development of the processing industry, while the demand for strips increases, higher requirements are placed on the quality of strips. In the cold-rolled strip rolling production line (including the subsequent processing flow), with the improvement of process equipment, the operating speed of the entire unit has increased year by year, and the strips produced and processed are developing in the direction of wide and thin. In order to adapt to the strip The high-speed continuous production, the strip steel is easy to deviate from the center line of the unit during the high-speed transmission process, resulting in strip damage and production loss. Reduced product quality and yield. Therefore, in these large-scale production lines, strip p...
