Multi-station automatic sampling inspection and production returning method based on AGV

Abstract

The invention provides a multi-station automatic sampling inspection and production returning method based on an AGV. The method comprises the following steps: step 1, conveying a workpiece to a to-be-inspected area; step 2, enabling the AGV to convey the workpiece from the to-be-inspected area to an inspection area; step 3, enabling an inspection device to inspect the workpiece; if the workpieceis inspected to be qualified, entering the step 4; and if the workpiece is inspected to be unqualified, entering the step 5; step 4, returning the workpiece for production; and step 5, alarming to prompt and performing waste disposal on the unqualified workpiece. The multi-station automatic sampling inspection and production returning method have the following advantages: with the utilization of an AGV trolley, the automation and intellectualization of a to-be-inspected workpiece in an entire process from submission to production returning are completed; by introducing an MES system, the individual inspection and information summarization of a workpiece having different requirements for different stations are guaranteed; and with the utilization of an RFID technology, the whole-process monitoring on a single to-be-inspected workpiece is implemented. Therefore, the defects of low efficiency, relatively large fault tracking difficulty, large manpower cost investment, relatively high demand on experience of a technician and the like in the traditional sampling inspection and production returning scheme are solved.

Description

technical field [0001] The invention proposes an AGV-based multi-station automatic sampling inspection and production return scheme, which belongs to the field of equipment production and is especially suitable for automobile powertrain production lines with production capacity rhythm requirements. Background technique [0002] In the process of equipment manufacturing, the requirements for the size and shape and position accuracy of the workpiece are getting higher and higher. In order to be able to perform efficient and stable measurement and control of workpiece size and shape accuracy, efficient and stable sampling inspection and return production schemes are particularly important. The equipment production line used in the traditional manufacturing industry usually adopts manual sampling inspection and return production scheme. This manual sampling inspection and production return scheme has the advantages of strong adaptability and low initial investment, but it also ...

Problems solved by technology

This manual sampling inspection and production return scheme has the advantages of strong adaptability and low initial investment, but it also has the following shortcomings: first, it cannot guarantee efficient and stable sampling inspection and production return efficiency; second, it is not conducive to the statistics of workpiece inspection result information 1. Induction, it is difficult to trace faults; 3. Long-term investment of a lot of labor costs is required, and the requirements for technical personnel experience are relatively high

The problem with this method is that this method is only suitable for the detection after the production and processing of the product, and it cannot realize the simultaneous detection and return to production, and the efficiency is low

For the situation where large workpieces require equipment handling or complex detection and large volume of detection equipment, this solution has obvious shortcomings
