Mistake-proofing system for electric tightening gun of tightening

Abstract

The invention discloses a mistake-proofing system for an electric tightening gun of tightening. The system comprises an upper computer, a tightening gun control module and a video monitoring and analyzing module, wherein the upper computer is used for acquiring vehicle to-be-processed information from a preset product processing database and sending the vehicle to-be-processed information to the tightening gun control module; the tightening gun control module is used for receiving the vehicle to-be-processed information and sending corresponding tightening data information to the tightening gun according to the vehicle to-be-processed information so as to make the workers operate by controlling the tightening gun according to the tightening data information; the video monitoring and analyzing module is used for shooting an operation video of the workers operating the tightening gun onsite, acquiring a video frame at a preset interval from the operation video, performing image template analysis and comparison on the video frame and the pre-stored operation process picture, and triggering an alarm device to start if the video frame is inconsistent to the operation process picture. The system can remind the workers of abnormal operation and has an alarming and correcting function to the workers. The mistake-proofing system for the electric tightening gun of tightening provided by the invention can be used for real-time monitoring the assembly line.

Description

technical field [0001] The invention relates to the field of information technology, and more specifically, relates to an error prevention system for an electric tightening gun of an assembly line. Background technique [0002] Thread connection is one of the most commonly used methods of combining machine parts. Electric tightening gun is a kind of equipment often used in assembly operations. It can tighten the nut on the screw with a certain set torque to play a role fixation. It is more common in automobile assembly lines, such as the fixing of automobile engine end covers, the fixing of automobile tires, etc. Because of its high reliability and good repeatability, it can ensure the tightening process requirements and reduce the labor intensity of workers, so it is widely used in production. However, electric tightening guns often require employees to operate, which will result in some inevitable human errors. For example, if the screw is not screwed, or the same part ...
