Problems solved by technology

[0005] The object of the present invention is to provide a kind of nut three-dimensional imaging detection device, to solve the existing nut detection method proposed in the above background technology, most of them are detected by manual detection method, this detection method has many shortcomings, In the face of mass production of nuts in factories, manual inspection is obviously very unrealistic, so most of them use sampling inspection for inspection. Even if sampling inspection is used, it is very laborious and laborious, and the detection efficiency is very low. Only the surface condition of the thread can be detected, and the internal defects of the thread cannot be known. At the same time, most inspectors can only inspect one type of nut. If different types of nuts are inspected, it is easy to affect the accuracy of the inspector. question

Embodiment 1

[0038] see Figure 1-Figure 9, the present invention provides a nut three-dimensional imaging detection device, including a data acquisition module, a data storage module, a data matching module and a central processing unit, the data acquisition module includes an X-ray machine 8 and a camera 12, and the data storage module is a bolt model library, including For the data of multiple different types of nuts, the data matching module compares and matches the collected data with the stored data, and the central processing unit is installed in the control panel 3;

[0039] A protective door 2 is fixedly installed on the front end of the outer shell 1, a control panel 3 is fixedly installed on the front end of the protective door 2, a base 4 is fixedly installed under the protective door 2, and a first lead plate 5 is fixedly installed on the right end inside the outer shell 1. A second lead plate 6 is fixedly installed on the protective door 2, a partition 7 is fixedly installed ...

Embodiment 2

[0043] The first lead plate 5 is provided with five groups altogether, and the first lead plate 5 of five groups is respectively installed in the left end, the right end, the rear end, the top end and the bottom end of the outer casing 1, wherein the first lead plate 5 of the left end, the right end and the rear end There are card slots at the middle position of the center, and the partition plate 7 is engaged and connected with the outer casing 1 through the chute; there are several groups of cameras 12, and several groups of cameras 12 are connected to the U-shaped track 10 by sliding. The groove 11 is set at the middle position of the partition 7, and the U-shaped groove 11 runs through the front end and the upper and lower ends of the partition 7. The width of the U-shaped groove 11 is greater than the diameter of the turntable 9; each group of cameras 12 is correspondingly provided with a set of Fixed plate 15, the bottom end of every group of fixed plate 15 is provided wi...

Embodiment 3

[0046] The round groove 30 is connected to the ejector pin 33 through a snap fit, and the tooth groove 31 and the cavity 32 are connected through a snap fit. The weighing pan 38 is fixedly connected to the push rod 33 by welding, and the second motor 37 is installed at the center of the weighing pan 38 .

[0047] In the present embodiment, weighing disc 38 at first resets the weight of rotating disc 9 to zero, after putting on nuts, calculates the quality of nuts, compares with the data stored in the database, and detects whether the weight of nuts is qualified, then passes through second motor 37 Work, drive the turntable 9 and the nut on it to rotate, facilitate the camera 12 to complete the data reading work on the nut.

[0048] A detection method of a nut stereoscopic imaging detection device, the detection method specifically includes the following steps:

[0049] Step 1: Enter the data models of different types of nuts in the data storage module;

[0050] Step 2: Open ...

Abstract

The invention discloses a nut stereo imaging detection device and method. The nut stereo imaging detection device comprises a data acquisition module, a data storage module, a data matching module and a central processor, the data acquisition module comprises an X-ray machine and a camera, and the data storage module is a bolt model library and comprises data of various different types of nuts; and the data matching module is used for comparing and matching the acquired data with the stored data. The method comprises the following steps: establishing the data model library in which data of various different types of nuts are stored, providing comparison objects for the device to detect the different types of nuts, establishing a data model of the detected nut through the camera and the X-ray machine, and comparing the data model read at this time with the nut data input in advance by using the data matching module. By using the detection mode, not only can the appearance defects of the nut be detected, but also the internal condition of the nut can be detected, and the situation that the nut is not enough in structural strength and damaged during use is avoided.

Description

technical field [0001] The invention belongs to the technical field of nut detection, and in particular relates to a nut stereoscopic imaging detection device, and more particularly relates to a nut stereoscopic imaging detection device and a detection method. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A component that must be used in all manufacturing machinery is divided into several types such as carbon steel, stainless steel, and non-ferrous metal according to different materials; [0003] Most of the existing nut detection methods are detected by manual detection. This detection method has many shortcomings. Facing the nuts produced in large quantities in factories, manual detection is obviously very unrealistic, so most of them use Sampling inspection method is very labor-intensive even if sampling inspection method is used, and the inspection efficiency is very low. At the same time, manual inspe...
