Abstract
The utility model relates to the technical field of on-machine measurement and especially to a machine vision on-machine measuring system equipped with backlight sources. The machine vision on-machine measuring system is composed of a camera shooting module, a control module, a measured object, and a tool clamp. The camera shooting module may perform image acquisition, signal conversion, and signal transmission and is mutually connected and communicated with the control module. The measured object is installed on the tool clamp. The tool clamp is equipped with a plurality of backlight sources composed of LED lamps and scattering plates. The LED lamps are embedded into grooves on the tool clamp. The scattering plates are arranged over the LED lamps. The backlight sources are disposed under the measured object so as to enhance the imaging brightness of the measured object and increase the definition and the identification precision of an image. In addition, the scattering plate changes point light to scattered light or parallel light, achieving uniform light brightness. Therefore, effects of achieving consistent definition of the entire image, decreasing image deformation caused by light, and substantially increasing the measuring precision of the measuring system are achieved.
Description
Technical field
The utility model relates to on-machine measurement technical field, particularly a kind of machine vision on-machine measurement system with backlight.
Background technology
Along with scientific and technical progress and improving constantly Product Precision requirement, on-machine measurement technology is applied in machining more and more, by in real time the geometric properties of workpiece being measured on lathe, and instruct subsequent machining technology according to measurement result, thereby obtain higher machining precision.In numerous measuring systems, measuring system based on machine vision is approved gradually and is applied because of the characteristic of its heed contacted measure, it not only can be measured in real time to workpiece features, and can be according to the size of workpiece, by parameters such as adjustable lens offset distances, automatically adjust measurement range, have measuring accuracy high, measurement range is easy to adjust, and measures efficiency advantages of higher.
At present, the on-machine measurement system based on machine vision generally adopting, under normal optical is shone, adopt camera directly to take that machined object measures, it is not high that this metering system is merely able to meet some processing requests, and the measurement of some machined objects that transmittance is higher, for overlay film products such as OGS glass, because the transmittance of film is lower, the in the situation that of normal optical photograph, take machined object and the image boundary that obtains is fuzzy, cannot reach the resolution of identification, affect the accuracy of identification of image, therefore, cannot meet in-process measurement requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, imaging clearly, machine vision on-machine measurement system that accuracy of identification is high are provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of machine vision on-machine measurement system with backlight, is comprised of photographing module, control module, measured object and frock clamp.Photographing module can carry out image acquisition, signal conversion and signal transmission, and it and control module interconnect and communication alternately; Measured object location and installation is on frock clamp; Wherein, be provided with several backlights on frock clamp, backlight is comprised of LED lamp and astigmatism plate, and LED lamp embeds in the groove of frock clamp, and astigmatism plate is arranged at the top of LED lamp.
Above-mentioned a kind of machine vision on-machine measurement system with backlight, described backlight is connected with lathe internal electric source, can automatically be controlled by control module, also can external gauge tap manually control.
Compared with prior art, the beneficial effects of the utility model are: the utility model by arranging backlight below measured object, strengthen the brightness of image of measured object, improved sharpness and the accuracy of identification of image, simultaneously, backlight adopts astigmatism plate, point light is become to scattered light or directional light, can guarantee that luminance brightness is even, the sharpness of whole image is consistent, reduce the anamorphose that light causes, greatly improved the measuring accuracy of measuring system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is frock clamp and the back light source structure schematic diagram that the utility model embodiment provides.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, a kind of machine vision on-machine measurement system with backlight of the present utility model, is comprised of photographing module 1, control module 2, measured object 3 and frock clamp 4.Photographing module 1 can carry out image acquisition, signal conversion and signal transmission, and it and control module 2 interconnect and communication alternately; Measured object 3 location and installation are on frock clamp 4; The Shang He center, four angles of frock clamp 4 is respectively arranged with backlight groove, arranges and has respectively backlight 5, the astigmatism plate 52 that comprises LED lamp 51 and cover LED lamp 51 tops in groove; LED lamp 51 connects with power supply 6, and controls its break-make by control module 2.
During work, first control module 2 is connected power supply 6, LED lamp 51 is lit, and sees through the outside scattering of astigmatism plate 52 and becomes scattered light, now, control module 2 is controlled photographing module 1 work, obtain the view data of measured object, then carry out signal conversion, and transfer data to control module, carry out next step data analysis and compensation, to obtain accurate processing effect.
Claims (2)
1. the machine vision on-machine measurement system with backlight, by photographing module, control module, measured object and frock clamp, formed, photographing module can carry out image acquisition, signal conversion and signal transmission, and it and control module interconnect and communication alternately; Measured object location and installation is on frock clamp; It is characterized in that: on frock clamp, be provided with several backlights, backlight is comprised of LED lamp and astigmatism plate, LED lamp embeds in the groove of frock clamp, and astigmatism plate is arranged at the top of LED lamp.
