A workpiece missing monitoring system and detection method based on ultrasonic induction

Abstract

The invention discloses an ultrasonic induction based workpiece neglected assembly monitoring system and a detection method thereof. The monitoring system comprises an information acquisition system,an information processing system and a display alarm system, wherein the information acquisition system comprises an ultrasonic wave opposite irradiation device, a power amplifier and a first DC powersupply; the information processing system comprises a signal conditioning circuit, an information acquisition device, a control computer and a second DC power supply; and the display alarm system comprises a projector and a sound-light alarm. The workpiece neglected assembly monitoring system of the production line comprises the information acquisition system, the information processing system and the display alarm system, can automatically monitor whether there is neglected assembly of a workpiece or not on the production line in real time, realizes open type non-contact detection, only needs to perform initial parameter setting, does not need manual intervention in the monitoring process, reduces unnecessary waste of labor and time, helps to reduce the neglected assembly rate of workpieces in the production process and improves the overall quality and safety performance of products assembled by the workpieces.

Description

technical field [0001] The invention relates to the field of missing-installation monitoring of workpieces, in particular to a monitoring system for missing-installation of workpieces based on ultrasonic induction and a detection method thereof. Background technique [0002] In order to realize the detection of the missing assembly of workpieces in the manual assembly process of various industrial productions (especially automobile industrial productions), some special devices and methods have been adopted at home and abroad. 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 condu...

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.
