Metal strain gauge defect automatic detection system

Abstract

The invention discloses a metal strain gauge defect automatic detection system and belongs to strain gauge detection devices. The system comprises a feeding leveling mechanism, a visual detection mechanism, a laser coding mechanism, a waste product labeling mechanism and a mechanical hand assembly. The feeding leveling mechanism, the visual detection mechanism, the laser coding mechanism and the waste product labeling mechanism are installed on a feeding station, a visual detection station, a coding station and a waste product labeling station below the mechanical hand assembly respectively. The visual detection mechanism, the laser coding mechanism and the waste product labeling mechanism are connected to a control system. Operations such as feeding, visual detection, laser coding and waste product labeling are performed on strain gauges sequentially through multiple stations in the system. The visual detection mechanism detects strain gauges on the stations through a uniform image recognition standard, the waste product labeling mechanism performs spraying and labeling on the strain gauges which are detected to be unqualified, missing detection is effectively avoided, the strain gauge detection efficiency is further improved, and the manual labor intensity is reduced.

Description

technical field [0001] The invention relates to a strain gauge detection device, more specifically, the invention mainly relates to a metal strain gauge defect automatic detection system. Background technique [0002] Resistance strain gauge (Resistance strain gauge) is a kind of transducer (also known as resistance strain gauge) that can convert the strain on engineering components, that is, the size change into resistance change, referred to as strain gauge for short. Generally, it is composed of sensitive grid, lead wire, adhesive, substrate and cover layer. The finished strain gauge is a sandwich structure, which is composed of base material, metal foil and cladding material; the specifications and shapes of the strain gauge products are different, and the grids are arranged horizontally, vertically, 45 degrees obliquely and circularly, etc. There are uniaxial, Divided into biaxial and triaxial, the internal structure of the strain gauge is very small. Generally, the gr...
