Problems solved by technology

Since the tool is not a flat object but a rotating body, the light source of the existing detection device is prone to uneven illumination on the surface of the tool
Due to the complex geometry of the tool, the lighting system is not easy to illuminate the full range of the tool
In addition, the surface of the knife is a highly reflective surface, which is prone to spotlight effect
Therefore, the image quality of the tool captured by the existing detection device is not high, resulting in low recognition accuracy

Embodiment Construction

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0013] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set...

Abstract

The invention provides a detection device for detecting appearance of a tool. The detection device comprises a base, a controller, and a regulating mechanism, a rotary table, a photographing mechanismand a reader-writer electrically connected to the controller, separately. The regulating mechanism and the rotary table are arranged on the base adjacently, the rotary table fixes the tool and drivesthe tool to rotate; the photographing mechanism is arranged on the regulating mechanism and faces the rotary table; the photographing mechanism comprises a camera and a light source, the light sourceis of a semispherical cavity shape, the open end of the light source faces the rotary table, the reader-writer is used for reading information of the tool, and the controller controls the regulatingmechanism to regulate position of the camera, the illuminating brightness of the light source and the camera to photograph the tool. As the rotary table fixes the tool and drives the tool to rotate and the light source facing the rotary table is arranged, the semispherical inner wall of the light source can reflective rays for many times to eliminate shadows, so that the tool is polished effectively and the photographing quality and the recognition precision are improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device capable of detecting the appearance of a tool. Background technique [0002] In the process of machining, the size of the tool will directly affect the quality of the workpiece. In order to ensure the operation efficiency and processing quality, it is necessary to measure the produced tools with high precision. Since the cutting tool is not a plane object but a rotating body, uneven illumination tends to occur when the light source of the existing detection device is irradiated on the surface of the cutting tool. Due to the complex geometry of the tool, the lighting system is not easy to illuminate the full range of the tool. In addition, the surface of the knife is a highly reflective surface, which is prone to spotlight effects. Therefore, the image quality of the tool captured by the existing detection device is not high, resulting in low recognition accuracy. Conte...
