Infrared-induction-based neglected workpiece assembling monitoring system and detection method thereof

Abstract

The invention discloses an infrared-induction-based neglected workpiece assembling monitoring system and a detection method thereof. The monitoring system is composed of an information acquisition system, an information processing system and a display alarm system. The information acquisition system consists of an infrared correlation device, a power amplifier and first direct-current power supply. The information processing system includes a signal conditioning circuit, an information collector, a control computer and a second direct-current power supply. The display alarm system includes a projector and an acousto-optic alarm device. According to the invention, the system is composed of the information acquisition system, the information processing system and the display alarm system andthe information processing system employs the infrared correlation device, so that the system has the high stability and is capable of monitoring existence of neglected workpiece assembling at a production line automatically in real time on various conditions. Only the preliminary parameter setting is needed and no manual intervention is required in the monitoring process, so that the unnecessarymanpower and time waste are reduced; the neglected workpiece assembling rate during the production process is reduced; and the overall quality and safety of products assembled by the workpieces are improved.

Description

technical field [0001] The invention relates to the field of workpiece missing-installation monitoring, in particular to an infrared induction-based workpiece missing-installation monitoring system and a detection method thereof. Background technique [0002] At present, in order to realize the detection of missing parts in various industrial productions, especially in the manual assembly process of the automobile industry, some special devices and methods have been adopted at home and abroad. Although the currently used leak detection methods have their own advantages, they all have many deficiencies, such as the inability to realize real-time detection, a single detection object, and various detection restrictions. [0003] In terms of the currently commonly used methods for detecting missing workpieces: 1) Manual detection method: through a special person to conduct a comprehensive and specific missing inspection of each workpiece on the station to determine whether there...

AI Technical Summary

Problems solved by technology

The disadvantage is that the corresponding device must be designed according to the detection object, and the cost of the monitoring equipment is high, the volume is large, and the installation is very complicated

[0004] At present, in the production of workpiece assembly, the phenomenon of missing workpieces caused by various reasons will affect the performance of products that need to be installed with missing workpieces, and cause failures or even failures during use. cause accidents and endanger the safety of users

In addition, although many factories and enterprises have adopted some advanced methods and equipment to strengthen the detection of missing workpieces, the phenomenon of missing workpieces is still relatively common.
