Abstract
The invention provides a nut defect detection method, which comprises the steps of connecting a nut feeder with a feed inlet of a nut detector, starting the nut feeder, separating nuts with specific sizes to a carrying disc of the nut detector through the feed inlet, driving the nuts to be placed below a CCD camera by the carrying disc, carrying out photographing, transmitting photos of the nuts into a display screen, displaying the shapes of the nuts without defects in the display screen, displaying the positions of the nuts with defects in the display screen through comparison with the nuts without defects, starting a manipulator to work, taking out the nuts with defects on the carrying disc, and uniformly collecting the rest nuts. The invention improves the working efficiency of nut defect detection and prevents the occurrence of nut detection mistakes and omissions in the detection process.
Description
Technical Field
The invention relates to the technical field of nut detection, in particular to a nut defect detection method.
Background
At present, the requirement on the product quality is higher and higher in China, manual detection of size, embossing, thread pitch, slag inclusion and the like is mostly adopted in the accessory industry of mechanical manufacturing, particularly the nut manufacturing industry, the time consumption is long, the detection efficiency is low, more importantly, the detection quality cannot be guaranteed, and nuts without threads are often not detected before leaving a factory. With the development of science and technology, the requirements of modern industry on products are higher and higher, the labor cannot meet the requirements on product inspection and the quantity of the products, and with the continuous improvement of labor cost, great resistance is caused to enterprises, so that the detection efficiency of nuts needs to be improved.
Disclosure of Invention
The purpose of the invention is: the nut defect detection method is provided, the work efficiency of nut defect detection is improved, and the nut detection is prevented from being mistaken and missed in the detection process.
The technical scheme is as follows: a nut defect detection method comprises the steps of connecting a nut feeder with a feed inlet of a nut detector, starting the nut feeder, dividing a nut with a specific size to a carrying disc of the nut detector through the feed inlet, driving the nut to be placed below a CCD camera by the carrying disc, transmitting a picture of the nut into a display screen after the picture is taken, wherein the shape of the nut without defects is stored in the display screen, the position of the nut with defects is displayed in the display screen through comparison with the nut without defects, a manipulator starts to work, the nut with defects on the carrying disc is taken out, and the rest nuts are collected in a unified mode.
Preferably, a push plate mechanism for paving the nuts is arranged on the carrying disc of the nut detecting machine.
Preferably, the push plate mechanism comprises a linear module, a cylinder and a push plate.
Preferably, the straight line module level sets up and is used for supporting the cylinder, straight line module both sides are provided with the backup pad.
The invention realizes the following beneficial effects:
according to the invention, the push plate mechanism is arranged on the carrying disc of the detection machine for placing the nut, so that the nut is laid flat during detection, the camera can completely shoot the nut for statistical detection, the work efficiency of nut detection is improved, the missing detection of the nut is avoided, and the qualification rate of the nut is improved.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.
FIG. 1 provides a working schematic diagram for the present invention.
Detailed Description

Referring to fig. 1, a nut defect detecting method includes the following steps:
s1: connecting a nut feeder with a feed inlet of a nut detector;
s2: starting a nut feeder, and distributing nuts with specific sizes into a carrying disc of a nut detector through a feed port;
s3: the carrying disc drives the nut to be placed below the CCD camera, and after photographing is carried out, the picture of the nut is transmitted into the display screen;
s4: the shape of the nut without defects is stored in the display screen, and the position of the nut with defects is displayed in the display screen through comparison with the nut without defects;
s5: and the manipulator starts to work, the defective nuts on the carrying disc are taken out, and the rest nuts are collected uniformly.
The push plate mechanism for paving the nuts is arranged on the carrying disc of the nut detection machine, so that the nuts which are not detected in the stacked nuts are prevented.
The push plate mechanism comprises a linear module, a cylinder and a push plate, the cylinder drives the push plate to move up and down, the linear module drives the push plate to move back and forth to push the nut flat, and the work efficiency of nut detection is improved.
The straight line module level sets up and is used for supporting the cylinder, straight line module both sides are provided with the backup pad.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
