Embodiment 1

[0025]According to an embodiment of the present invention, a screw detection method is provided, which is applied to a screw detection machine, such asfigure 1 As shown, the method includes:

[0026]S101, place the screws on the glass plate of the screw inspection machine in turn;

[0027]S102: Obtain the pulse amount of each screw on the glass plate, and the pulse amount is used to represent the angle of the screw rotating with the screw detection machine;

[0028]In the related art, it is impossible to accurately control the screws for the non-indexed disc type screw inspection machine. Therefore, in the embodiment of the present invention, a screw detection method is proposed to realize the non-divided disc type screw inspection. The screw is precisely controlled in the machine. For example, such asfigure 2 As shown in the non-indexing disc inspection machine, there is a photoelectric sensor 6 in the non-indexing disc inspection machine, and the screw is sent to the glass plate of the non...

[0073]According to an embodiment of the present invention, there is also provided a screw detection device for implementing the above screw detection method, such asFigure 4As shown, the device includes:

[0074]1) The distribution unit 401 is used to place the screws on the glass plate of the screw inspection machine in sequence;

[0075]2) The first obtaining unit 402 is configured to obtain the pulse amount of each screw on the glass plate, and the pulse amount is used to represent the angle of the screw rotating with the screw detecting machine;

[0076]3) The second acquiring unit 403 is configured to acquire the first image of the first part of the screw when the pulse amount of the screw reaches the preset first pulse threshold;

[0077]4) The first detection unit 404 is configured to detect the first part of the screw according to the first image to obtain a first detection result;

[0078]5) The third acquiring unit 405 is configured to acquire a second image of the second part of the scr...

Embodiment 3

[0088]According to an embodiment of the present invention, a storage medium is also provided, the storage medium includes a stored program, wherein the above-mentioned screw detection method is executed when the program is running.

[0089]Optionally, in this embodiment, the storage medium is configured to store program code for executing the following steps:

[0090]S1, place the screws on the glass plate of the screw inspection machine in turn;

[0091]S2: Obtain the pulse amount of each screw on the glass plate, where the pulse amount is used to represent the angle of the screw rotating with the screw detection machine;

[0092]S3: Acquire a first image of the first part of the screw when the pulse amount of the screw reaches a preset first pulse threshold;

[0093]S4: Detect the first part of the screw according to the first image to obtain a first detection result;

[0094]S5: Acquire a second image of the second part of the screw when the pulse amount of the screw reaches a preset second pulse ...

Abstract

The invention discloses a screw detection method and device. The method comprises the steps that screws are placed on glass discs of a screw detector in sequence, and the pulse quantity of each screwon the glass disc is obtained; a first image of the first part of the screw is obtained under the condition that the pulse quantity of the screw reaches a preset first pulse threshold value; the firstpart of the screw is detected according to the first image to obtain a first detection result; a second image of the second part of the screw is obtained under the condition that the pulse quantity of the screw reaches a preset second pulse threshold value; the second part of the screw is detected according to the second image to obtain a second detection result; and the integral detection resultof the screw is determined according to the first detection result and the second detection result, and the screw is processed according to the integrated detection result. By virtue of the method, the problem of relatively low screw detection efficiency caused by the fact that the screw cannot be accurately controlled by a non-graduated disk type screw detector for detection is solved.

Description

Technical field[0001]The present invention relates to the field of industrial manufacturing, in particular to a screw detection method and device.Background technique[0002]The non-indexing disc type screw inspection machine uses a vibration plate to transport the screws to the optical glass plate in a non-fixed manner (the speed is about 300 pcs / min) in accordance with the nut facing down and the screw facing up. When the optical glass plate rotates and the screw is rotated to the detection area of ​​the optical detection mechanism on the side or front, the camera is triggered to take a picture, and the detection result is obtained after computer processing. Then, the optical glass disk continues to rotate, and the screw is rotated to the good OK or bad NG feeding position. According to the judgment result of the optical inspection system, the distributor blows the screws to the OK product outlet or the NG product outlet. Because the screw is not fixed in the designated position of ...
