Workpiece installation missing monitoring system based on pressure sensing and detection method by employing same

Abstract

The present invention discloses a workpiece installation missing monitoring system based on pressure sensing and a detection method by employing same. The monitoring system comprises an information collection system, an information processing system and a display alarm system; the information collection system comprises a pressure sensing device and a power amplifier; the information processing system comprises a signal processing circuit, an information collector, a control computer and a direct current power supply; and the display alarm system comprises a projector and an audible and visualalarm. The workpiece installation missing monitoring system comprises the information collection system, the information processing system and the display alarm system. The information collection system applies the pressure sensing device, and the pressure sensing device is good in stability and long in life, and can automatically monitor whether there is workpiece being missed in installation inreal time in various conditions. Initial parameter setting is only performed, human interference is not needed in the monitoring process, unnecessary manpower and time waste is reduced, a workpiece installation missing rate in the production process is reduced, and the whole quality and the safety performance of the 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 a pressure-sensing-based workpiece missing-installation monitoring system and a detection method thereof. Background technique [0002] In the prior art, some special devices and methods have been adopted at home and abroad in order to detect the missing assembly of workpieces in the manual assembly process of various industrial productions (especially automobile industrial production). Although the methods of missing detection currently used have their own advantages, there are many deficiencies, such as the inability to realize real-time detection, single detection object (a certain device can only realize the missing detection of a specific object), detection many restrictions etc. [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 an...

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.
