Problems solved by technology

If the angle of the light source cannot be changed and kept consistent, the light will be uneven and the quality of the captured image will be poor
[0004] Chinese patent CN201210497326.0 discloses a machine vision LED lighting source. This technical solution is provided with a diffuser plate on the irradiation surface of the LED matrix light source. In this case, richer brightness and incident angle can be obtained, and the light is uniform, but this technical solution cannot change the angle of the light source and keep the angle consistent, resulting in poor image acquisition effect

Abstract

The invention discloses a machine vision illumination light source, comprising a base plate, and a shell which is arranged in a manner of fitting with the base plate, wherein a driving component is arranged on the base plate; the driving component comprises a rotating part and a driving part; the rotating part comprises a knob; a bearing and a large bevel gear are sequentially arranged below the knob; the driving part comprises a small bevel gear; the small bevel gear is meshed with the large bevel gear; the small bevel gear is provided with a lead screw; the lead screw is provided with a sliding block; the sliding block is arranged in a manner of fitting with a sliding rail; the sliding block is connected with an LED (light emitting diode) module through a connecting rod; the LED module is positioned below the base plate. Meanwhile, the invention further discloses an operating method of the machine vision illumination light source. According to the machine vision illumination light source and the operating method of the machine vision illumination light source, an angle of the LED module can be adjusted through linkage by means of rotating the knob, and the consistence is kept; for different detection characteristics, the uniform illumination can be also realized under the condition of changing the direction of incident light, and the operation is convenient.

Description

technical field [0001] The invention relates to the field of photoelectric lighting, in particular to a machine vision lighting source and an operating method thereof. Background technique [0002] Machine vision is to use machines to replace our human eyes for detection and judgment. Traditional manual detection not only requires a lot of manpower but also is inefficient. Machine vision is often used for product quality inspection in the mass production process, especially in situations where the detection environment is dangerous and human vision is difficult to satisfy. Machine vision can greatly improve detection accuracy and detection speed, thereby improving production efficiency and avoiding deviations and errors caused by human visual inspection. Users in the market have higher and higher requirements for product quality and quality control. In this case, in order to improve the quality and competitiveness of products, machine vision will be a major trend. [00...
