Please refer to shown in Fig. 1, the embodiment of the present invention one provides a kind of detection system of frame glue coating syringe needle, comprises laser light-source device 1, fixed mount 2, optical lens 3, imageing sensor 4 and image processing apparatus 5, wherein:
Laser light-source device 1 comprises LASER Light Source 11 and transmitting terminal 12, and LASER Light Source 11 detects laser used for providing, and the detection system due to the present embodiment just make use of the directional characteristic of laser, therefore the brightness of LASER Light Source 1 and power requirement all do not need too high.According to the wave-particle duality of light, the wavelength of light is shorter, and ionic stronger, undulatory property is more weak, and parallel radiation ability is better, but wavelength is less than the laser of 400 nanometers close to ultraviolet light, and the cull in syringe needle 6 can be made to solidify and cannot wash again, and syringe needle 6 can only be scrapped.In the present embodiment, the wavelength of laser should be greater than 400 nanometers, and optimal wavelength is the argon laser of 514 nanometers.
Transmitting terminal 12 is hollow cylindrical, for determining direction and the lasing beam diameter of laser, will come from the Laser emission of LASER Light Source 11 to syringe needle 6 to be detected.Straight down, transmitting terminal 12 also arranges (namely perpendicular to surface level) to the transmit direction General Requirements of laser straight down.Situation in hole, generally slightly larger than the aperture of syringe needle 6 endoporus 60, with the endoporus 60 making laser beam cover syringe needle 6, can all reflect by laser beam.
Fixed mount 2, for fixedly mounting syringe needle 6 to be detected, comprises the fixed orifice of multiple different-diameter, with the syringe needle of corresponding different-diameter.Because the installation end of syringe needle 6 is generally external thread, the connected mode single screw between fixed mount 2 with syringe needle 6 is connected.Fixed mount 2 can installation planar movement arbitrarily, the syringe needle that will detect can be selected arbitrarily.When being installed on fixed mount 2 by syringe needle 6, the center line of syringe needle 6 endoporus 60 must be made to overlap with the center line of transmitting terminal 12.
Optical lens 3 is for amplifying the hot spot through syringe needle 6 endoporus 60.The needle aperture scope 0.2 ~ 0.5mm of current use, visual very difficult resolution, need be amplified by optical system, and the multiple of amplification changes by changing lens.
