An automatic detection system for metal strain gauge defects

Abstract

The invention discloses an automatic detection system for metal strain gauge defects, which belongs to a strain gauge detection device. The system includes a feeding leveling mechanism, a visual detection mechanism, a laser marking mechanism, a waste product marking mechanism and a manipulator assembly. The feeding leveling mechanism, visual inspection mechanism, laser coding mechanism and waste product marking mechanism are respectively installed on the feeding station, visual inspection station, coding station and waste product labeling station under the manipulator assembly; the visual inspection mechanism, laser Both the coding mechanism and the waste labeling mechanism are connected to the control system; multiple stations in the system perform operations such as loading, visual inspection, laser coding, and waste labeling on the strain gauge in sequence. The visual inspection mechanism uses a unified image recognition standard to identify The strain gauges on the workstations are tested, and the waste product marking system sprays marks on the unqualified strain gauges, which effectively avoids the occurrence of missed inspections, improves the efficiency of strain gauge detection, and reduces the labor intensity.

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 gage (Resistance strain gage) is a kind of transducer (also known as resistance strain gage), which can convert the strain on engineering components, that is, dimensional change into resistance change, and is referred to as strain gage 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...
