Error-proofing monitoring system and method for automobile engine valve assembling process

Abstract

The invention discloses an error-proofing monitoring system for an automobile engine valve assembling process. The error-proofing monitoring system comprises a detection platform, a control system and a man-machine information communication panel, wherein the detection platform comprises two roller way conveying tables, three stoppers, a jacking device, a barcode scanning gun, a laser ranging sensor and a single-shaft robot; the control system comprises a single-shaft robot programming controller, a programmable controller, a data acquisition card, an industrial personal computer and a proximity switch; and the man-machine information communication panel comprises a display, a touch screen and a combined aural and visual alarm. According to the error-proofing monitoring system disclosed by the invention, after the assembly of an air valve is finished, a correct-error result is immediately obtained according to an assembling situation, and an error assembling result is classified according to error types so as to provide a maintenance prompt for a maintainer. The error-proofing monitoring system disclosed by the invention is arranged at one section of an engine assembly line and only allows correctly assembled cylinders to pass the detection and enter a subsequent continuous engine assembling process in a working mode so as to reach an error-proofing purpose.

Description

technical field [0001] The invention relates to assembly equipment on an automobile engine production and assembly line, in particular to an error-proof monitoring system and method for the assembly process of an automobile engine valve group. Background technique [0002] Nowadays, with the improvement of people's living standards and the gradual improvement of the market economy, the demand for cars has increased linearly, and new car varieties have emerged in an endless stream. Accompanied by the huge automobile output, the most critical part of its production - the automatic production and assembly of the engine has also posed severe challenges. The fast production rhythm and fast delivery speed, and the manufacturing process of single-line multi-variety engines often appear on many production lines. For various reasons, there are always a series of potential installation problems on the automatic assembly line of engines. Among these, the risk of errors in valve assemb...

AI Technical Summary

Problems solved by technology

The lock block in the valve group is an extremely small part. During the assembly process, there are often problems such as missing, missing, reversed and wrong installation, which will cause engine parts to be repaired and scrapped, which greatly increases the engine. manufacturing cost

[0003] In the engine manufacturing plant, the production of the engine must carry out error-proof testing on the assembly of the valve group on the cylinder head. Most of the domestic valve group detection technologies are for the quality inspection of individual parts of the unassembled valve group, or Judging the correctness of the assembly of a single valve group part, but there is no comprehensive case study on the computer error-proof monitoring technology for the assembly process of the automobile engine valve group, that is, the final assembly of the entire valve group is given the type Categorize and judge assembly results

The vast majority of domestic factories still rely on traditional manual inspection, which results in low accuracy and is limited by many factors. It wastes human resources and fails to meet the requirements of today's full automation of production. It is difficult to compare with today's High-efficiency production matches, let alone keep up with the pace of international advanced error-proofing technology
