Conveyor belt monitoring device based on image and photoelectric information fusion

Abstract

The invention discloses a conveyor belt monitoring device based on image and photoelectric information fusion. The conveyor belt monitoring device comprises a conveyor belt body, a photoelectric emitter and a photoelectric receiver, and is characterized in that the conveyor belt body comprises a belt body and at least two rotating shafts, the rotating shafts are sleeved with the belt body, and the rotating shafts rotate under the action of an external power source; and the monitoring device further comprises a base plate, the base plate is fixedly arranged in the space defined by the belt body, the base plate is fixed to an external rack through a hard rod piece, a sliding groove is formed in the upper surface of the base plate and arranged in the conveying direction of the conveying belt, and an upper sliding block is slidably connected into the sliding groove. The conveyor belt monitoring device has the advantages that an upper limiting shaft and a lower limiting shaft are both fixedly connected with the external rack, the movement speed of the belt body on the side, close to the rotating shaft, of receding grooves is directly controlled by the rotating shaft and cannot be changed, but the movement speed of the belt body between the two receding grooves can be adjusted, so that the movement speed of workpieces is adjusted, and the aim of adjusting the distance between the multiple workpieces is achieved.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to a conveyor belt monitoring device based on fusion of images and photoelectric information. Background technique [0002] With the rapid development of the economy, conveyor belts have been widely used in machinery, light industry, food, chemical industry, logistics transportation, assembly line operations and other industries and fields. Now the common method is to use photoelectric sensors to monitor the workpieces on the conveyor belt. Detection, but the industrial site environment is complex, it is difficult to achieve accurate detection with a single sensor, the reliability is not high, and it is easy to make wrong judgments, resulting in the density of workpieces on the conveyor belt, lack of monitoring or inaccurate monitoring, resulting in intermittent workpieces Even congestion, which affects the efficiency of the entire production line.

[0002] With the rapid development of the economy, conveyor belts have been widely used in machinery, light industry, food, chemical industry, logistics transportation, assembly line operations and other industries and fields. Now the common method is to use photoelectric sensors to monitor the workpieces on the conveyor belt. Detection, but the industrial site environment is complex, it is difficult to achieve accurate detection with a single sensor, the reliability is not high, and it is easy to make wrong judgments, resulting in the density of workpieces on the conveyor belt, lack of monitoring or inaccurate monitoring, resulting in intermittent workpieces Even congestion, which affects the efficiency of the entire production line

[0003] After retrieval, the patent with the publication number CN201746081U discloses the scheme of the same name, but this scheme only discloses the working principle of the photoelectric transmitter and photoelectric receiver, and after the relative distance of the workpiece on the production line is detected, only a warning can be issued, and the alignment cannot be directly completed. The adjustment of the workpiece position reduces the production efficiency, so it is particularly important to propose a conveyor belt monitoring device that can directly solve the problem of too short distance between two workpieces on the conveyor belt
