Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a CCD vision device for an optical curve grinding machine. Background Art

[0002] In the modern precision manufacturing industry, grinding machines, as key equipment, are widely used for surface finishing of various metal and non-metal workpieces to achieve the required dimensional accuracy and surface finish. In this process, accurate and real-time monitoring of the contact status between the grinding head and the workpiece and the processing effect is crucial to ensuring processing quality, improving production efficiency and reducing scrap rates. In order to achieve effective monitoring of this process, a common and efficient method is to use an integrated visual inspection system, among which CCD cameras are widely used due to their high sensitivity, high resolution and fast response capabilities. CCD cameras can capture real-time images of the processing process. Through sophisticated image processing algorithms, they can analyze the position of the grinding head, the movement trajectory and the changes on the workpiece surface, providing operators with intuitive feedback on the processing effect.

[0003] However, in practice, due to the nature of grinding, the high-speed friction between the workpiece and the grinding head generates a large amount of fine metallic and non-metallic dust. Under the influence of gravity, this dust easily settles on key components of the visual inspection system, especially the light source located opposite the CCD camera.

[0004] The light source is a key factor in CCD camera imaging quality. Once dust accumulates on its surface, it will directly cause light scattering and reduce brightness, which in turn affects the clarity and contrast of image acquisition. Severe dust accumulation can even completely disable the fill light effect of the light source, making it impossible for the CCD camera to capture effective processing images, thus seriously weakening the monitoring capabilities of the visual inspection system and the level of visual management of the processing process. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a CCD vision device for an optical curve grinder, which solves the problems raised by the above-mentioned background technology.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a CCD vision device for an optical curve grinder, comprising a base, a workpiece fixing table, and a grinding head, a CCD camera is installed on the top of the base, and a light source is installed on the bottom of the base, a light-transmitting shield is installed on the upper part of the light-emitting end of the light source, and a dust reduction mechanism is provided on the side of the workpiece fixing table, which can absorb the dust generated by the grinding head during the grinding process.

[0007] Furthermore, the CCD camera is located directly above the protective cover, and the shooting area of the CCD camera can cover the processing area of the grinding head.

[0008] Furthermore, the protective cover is arranged outside the light source, and a window is installed inside the protective cover. The window is made of transparent glass, and the position of the window corresponds to the position of the light-emitting end of the light source.

[0009] Furthermore, the dust reduction mechanism includes a dust suction head and a dust suction pipe, the dust suction head is located on one side of the workpiece fixing platform, the dust suction pipe is installed on the base, and the dust suction pipe is connected to the dust suction head.

[0010] Furthermore, the vacuum head is a trumpet-shaped structure, with the end with a smaller diameter being connected to the vacuum tube and the end with a larger diameter facing the processing area of the grinding head.

[0011] Furthermore, a display screen is installed on the top of the base, and the CCD camera is connected to the display screen via a communication wire.

[0012] The utility model provides a CCD vision device for an optical curve grinder. Compared with the prior art, it has the following advantages:

[0013] The grinding machine's processing vision device, through a combination of a protective cover and a transparent window, effectively isolates a small amount of dust from direct contact with the light source, significantly reducing the dust's impact on the light source's fill-in effect, thereby ensuring that the CCD camera can continuously capture clear, high-quality processing images. At the same time, the introduction of a dust suppression mechanism effectively adsorbs and removes most dust during the grinding process, further ensuring the cleanliness of the light source and the environment surrounding the CCD camera. This dual protection mechanism not only enhances the stability and reliability of the visual inspection system, but also significantly reduces processing monitoring errors caused by dust interference, providing strong technical support for improving grinding machine processing accuracy, ensuring product quality, and increasing production efficiency.

The dust reduction mechanism 7 is located in the processing area of the grinding head 3, that is, on the side of the workpiece fixing table 2. The dust reduction mechanism 7 can absorb the dust generated by the grinding head 3 during the grinding process, thereby preventing the dust generated during the processing from falling on the surface of the light-emitting part of the light source 5 and affecting the CCD camera when acquiring images.
