Embodiment Construction
[0012] As shown in the accompanying drawings, the present invention has two groups of curved columns composed of upper and lower arc plates, which are symmetrically arranged. Three primary color red R, green G and blue B fluorescent tubes are respectively installed between the upper and lower arc plates of each group. The basic color fluorescent tubes are staggered to form an arc column, and the distance from each fluorescent tube to the center of the arc is equal. The excitation high voltage of the fluorescent tubes is provided by the power distributor, and the computer is connected to the power distributor through the RS232 interface. The group controls the on and off of each fluorescent tube.
[0013] The excitation voltage of the trichromatic fluorescent tube is 1100V, the spectral range of the excited red light is 630-680nm, the spectral range of the excited green light is 540-580nm, and the spectral range of the excited blue light is 435-470nm. The radius of the arc is 2...

The invention discloses an arc column color separation controllable fluorescent light source used for visual separation of fruits and vegetables. Two groups of arc columns are symmetrically arranged, and each group of arc column is composed of an upper arc plate and a lower arc plate; a red fluorescent tube, a green fluorescent tube and a blue fluorescent tube are arranged between the upper arc plate and the lower arc plate of each group of arc column; the three fluorescent tubes are interlacedly arrayed to form an arc column shape; the distanced from the three fluorescent tube to the center of the arc column are equal; the excited high pressure is supplied by a power supply distributor, and a microcomputer is connected with the power supply distributor through a RS232 interface; and the microcomputer can control the on-off of each fluorescent tube and the on-off of the three fluorescent tubes separately or in group. The three fluorescent tubes are arranged into circular arc shape according to the shapes of the fruits and vegetables so that the illumination intensity on the surfaces of the fruits and vegetables are uniform; because the microcomputer can control the on-off of each fluorescent tube and the on-off of the three fluorescent tubes in group, the combination of the fruits and vegetables of different colors and illumination intensities are convenient; the color separation controllable fluorescent light source can be matched with the separation of the fruits and vegetables, and the access and the light source adjustment of the fruits and vegetable can be conducted corporately.
Description
technical field [0001] The invention relates to an arc-column color-separation controllable fluorescent light source for visual sorting of fruits and vegetables. Background technique [0002] Fruit and vegetable sorting is an important link in the postharvest treatment and packaging of fruits and vegetables. Picked fruits and vegetables have individual differences in maturity, nutrition, cleanliness, etc., and have the disadvantages of low efficiency, low accuracy, high labor intensity, and easy fatigue of manual judgment. Using machine vision to automatically determine the maturity, nutrient level and washing cleanliness of harvested fruits and vegetables will greatly improve the automation level of fruit and vegetable sorting. One of the key components of fruit and vegetable visual sorting equipment is the controllable light source. Contents of the invention [0003] The object of the present invention is to provide an arc-cylindrical color-separation controllable fluo...
