Surface defect detection device and method of stamping parts based on machine vision

Abstract

The invention discloses a surface defect detection and method of stamping parts based on machine vision. The surface defect detection device comprises a shell, wherein the left end of the top part ofan inner cavity of the shell is fixedly connected with a first sliding seat; the outer surface of the first sliding seat is connected with a first slider in a sliding manner; the bottom part of the first slider is fixedly connected with a second sliding seat; the outer surface of the second sliding seat is connected with a second slider in a sliding manner; the bottom part of the second slider isfixedly connected with a first electric telescopic rod; the bottom part of the first electric telescopic rod is fixedly connected with a first support plate; the middle end of the bottom part of the first support plate is fixedly connected with a CCD (Charge-Coupled Device) camera; the surrounding of the bottom part of the first support plate is fixedly connected with headlamps. According to the surface defect detection and method of the stamping parts based on the machine vision disclosed by the invention, through effects of the first slider, the second slider, the first electric telescopic rod and the headlamps as well as a third slider, a second electric telescopic rod, a second motor and a third electric telescopic rod, a requirement on all-around detection without dead corners on thestamping parts can be met, and the device is convenient to use by people.

Description

technical field [0001] The invention relates to the technical field of inspection devices, in particular to a device and method for detecting surface defects of stamping parts based on machine vision. Background technique [0002] Stamping processing is a production technology that uses the pressure of stamping equipment to separate the plate in the stamping die, thereby obtaining product parts of a certain shape and size. It has the characteristics of intelligence, precision, high efficiency, and high speed. However, in the stamping production process , there will always be waste products caused by objective factors such as processing errors, material defects, and mold damage. If they cannot be detected and eliminated in time, it will seriously affect the subsequent assembly and other links, resulting in a decline in the overall quality of the product and an increase in costs. , affecting production efficiency, but the existing detection device has a low degree of automatio...

[0002] Stamping processing is a production technology that uses the pressure of stamping equipment to separate the plate in the stamping die, thereby obtaining product parts of a certain shape and size. It has the characteristics of intelligence, precision, high efficiency, and high speed. However, in the stamping production process , there will always be waste products caused by objective factors such as processing errors, material defects, and mold damage. If they cannot be detected and eliminated in time, it will seriously affect the subsequent assembly and other links, resulting in a decline in the overall quality of the product and an increase in costs. , affecting production efficiency, but the existing detection device has a low degree of automation, which not only increases the consumption of manpower, but also reduces the detection efficiency. Therefore, we propose a surface defect detection device for stamping parts based on machine vision
