AGV-based multi-station automatic sampling inspection and production return method

Abstract

Provided is an AGV-based method for automated sampling inspection and reworking for multiple stations (1). The method comprises the following steps: step 1, conveying a workpiece to a waiting region; step 2, an AGV conveying the workpiece from the waiting region to an inspection region; step 3, an inspection device inspecting the workpiece, wherein if the workpiece passes the inspection, step 4 is executed, and if the workpiece fails to pass the inspection, step 5 is executed; step 4, subjecting the workpiece to reworking; and step 5, issuing an alert and scrapping a workpiece failing inspection. The invention has the following advantages: the use of an AGV trolley enables an automated and intelligent process from the conveyance of a workpiece for inspection to reworking of a workpiece; the use of a MES system ensures customized inspection and information aggregation of workpieces having different requirements in different stations (1); and the use of an RFID technique enables full monitoring of a single workpiece to be inspected. The invention eliminates the following defects of a conventional sampling inspection and reworking solution: low efficiency, difficultly in fault tracing, high labor costs, high investment, and high requirements on the experience of technical staff.

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 ...

AI Technical Summary

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
