Detection system

Technical Field

The present invention relates to a detection system, and more particularly, to a detection system capable of accurately detecting a blade by using an illumination device to illuminate the blade of a cutting tool, so as to generate a light-dark difference in the blade and further generate an obvious profile.

Background

In general, after a tool such as a drill point and an end mill is produced, a Charge Coupled Device (CCD) is used to detect the shape characteristics of the edge of the tool, and in order to make the detection result more accurate, an illumination device can be used to illuminate the edge and make the contour of the edge clearer.

Therefore, how to solve the above problems is an urgent issue to be developed by the related art.

Disclosure of Invention

The main objective of the present invention is to provide an illumination device with at least three sets of annularly arranged light emitters, and select and use an appropriate light emitter according to the placement angle of the knife, so that the light and shade contrast is generated on the multiple edge surfaces of the knife, and the picture taken by the camera device can be used by the detection device to clearly distinguish each edge surface, thereby improving the detection accuracy.

In order to achieve the above object, the present invention provides a detection system comprising an illumination device, a photographing device and a control device connected to the illumination device and the photographing device, wherein the photographing device is connected to the detection device, the illumination device has at least three sets of light emitters arranged in a ring shape, and the control device performs angle calculation according to an image of a blade of a tool photographed by the photographing device and controls an appropriate light emitter to emit light according to a calculation result.

In an embodiment, the lighting device includes a body, the body is provided with a hollow portion penetrating through the upper surface and the lower surface, the light emitter is disposed on the lower surface of the body and surrounds the side of the hollow portion, and the photographing device is disposed above the body of the lighting device and faces the hollow portion of the body.

In the detection system, the photographing device is connected to the detection device, when the detection system detects the blade of the cutting tool, the control device first lights all the light emitters to illuminate the blade of the cutting tool, and the photographing device photographs an image of the blade and transmits the image to the control device; when the control device receives the blade image, the angle of the blade is calculated, and the light of the light emitter is controlled according to the angle, at the moment, the photographic device shoots the blade picture again and transmits the blade picture to the detection device for detection.

Detailed Description

As shown in fig. 1 to 3, as can be clearly seen from the drawings, the present invention includes an illumination device 1, a photographing device 2, a detection device 3 and a control device 4, wherein the illumination device 1 and the photographing device 2 are connected to the control device 4, and the detection device 3 is connected to the photographing device 2; the lighting device 1 is provided with a body 11 and at least three groups of light emitters 12, wherein the body 11 is provided with a hollow portion 111 penetrating through the upper surface and the lower surface, and the light emitters 12 are arranged on the lower surface of the body 11 and surround the sides of the hollow portion 111; the imaging device 2 is disposed above the main body 11 of the illumination device 1 and faces the hollow portion 111 of the main body 11, and the placement seat 6 for placing the tool 5 is disposed below the hollow portion 111 of the illumination device 1.

As shown in fig. 1, fig. 4 and fig. 5, it can be clearly seen that the detection system performs the following steps:

(100): the shank 51 of the tool 5 is positioned on the placing seat 6 so that the blade 52 of the tool 5 faces the hollow portion 111 of the lighting device 1 and the blade 52 of the tool 5 has one or more blade surfaces 521.

(101): the controller 4 turns on all the light emitters 12 to illuminate the blade 52 of the blade 5, and the imaging device 2 captures an image of the blade 52 and transmits the image to the controller 4.

(102): the control device 4 calculates the angle of the blade 52 according to the image transmitted by the photographing device 2, and controls the partial illuminator 12 to illuminate according to the angle; the angle of the blade 52 is an angle with respect to the light emitter 12, and the control device 4 calculates which light emitter 12 the blade surface 521 is close to based on the received image and lights the light emitter 12.

(103): the image pickup device 2 picks up the image of the blade 52 again and transmits the image to the detection device 3 for detection.
