Description
Technical field
The utility model relates to a kind of Workpiece detecting device, particularly a kind of device of non-contact detection workpiece form and position tolerance.
Background technology
In the production of some high-precision workpiece, need to detect the form and position tolerance of workpiece after some techniques, traditional detection mode mostly is workman's manual operation and measures, this detection time is long, efficiency is low, labour intensity is large, accuracy of detection is low, easily occurs undetected or detects wrong situation.Meanwhile, when carrying out conventional contact to high-precision workpiece and detecting, usually can destroy the precision of workpiece, bring unnecessary loss.Based on above situation, in the ever-increasing situation of manufacturing industry product demand, the form and position tolerance that measuring workpieces is carried out in manual operation cannot meet current demand.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is the device proposing a kind of non-contact detection workpiece form and position tolerance, can accurately detect fast workpiece form and position tolerance, save labor cost, there is easy to operate, that accuracy of detection is high, efficiency is high, usable range is wide, simple and practical feature.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of device of non-contact detection workpiece form and position tolerance, comprise programmable controller PLC, described programmable controller PLC is electrically connected with Machine Vision Inspecting System by its analog output end, Machine Vision Inspecting System is electrically connected with computing machine USB port, be electrically connected by RS232C interface between computing machine with programmable controller PLC, first is fixedly mounted on the upstream position of the second sensor by production line to level sensor, programmable controller PLC and Machine Vision Inspecting System, workpiece, first to be electrically connected to form loop in turn to level sensor, programmable controller PLC and pusher driver, pusher, workpiece, second to be electrically connected to form loop in turn to level sensor.
Described Machine Vision Inspecting System comprises integrated pattern collection and data analysis in the industrial intelligent camera of one and light source module, and light source module is external unit, provides light required when taking pictures.
Data transmission is carried out by ICP/IP protocol between described programmable controller PLC and computing machine.
Because the utility model is gathered image by Machine Vision Inspecting System, detected by the form and position tolerance of computing machine to workpiece, and pass through pusher, complete picking out of defective products, can be applicable in product line, avoid the interference of subjective factor in the manual detection method of contact, can quick, objective, exactly workpiece form and position tolerance is detected, greatly improve quality and the output of product, there is simple to operate, that accuracy of detection is high, efficiency is high, usable range is wide, economical and practical feature.
Accompanying drawing explanation
Fig. 1 is the utility model system principle diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, a kind of device of non-contact detection workpiece form and position tolerance, comprise programmable controller PLC, described programmable controller PLC is electrically connected with Machine Vision Inspecting System by its analog output end, Machine Vision Inspecting System is electrically connected with computing machine USB port, be electrically connected by RS232C interface between computing machine with programmable controller PLC, first is fixedly mounted on the upstream position of the second sensor by production line to level sensor, detection is positioned to workpiece for measurement, programmable controller PLC and Machine Vision Inspecting System, workpiece, first to be electrically connected to form loop in turn to level sensor, programmable controller PLC and pusher driver, pusher, workpiece, second to be electrically connected to form loop in turn to level sensor.
Described Machine Vision Inspecting System comprises industrial intelligent camera and light source module, and light source module is external unit, provides light required when taking pictures.
The integrated pattern collection of described industrial intelligent camera and data analysis are in one.Machine Vision Inspecting System can be sampled by the information of industrial intelligent camera to workpiece to be detected, and sampled result is sent to computing machine.Computer-internal is provided with storing template, can contrast, testing result is sent to programmable controller PLC to sampled result and standard morpheme tolerance value.
Data transmission is carried out by ICP/IP protocol between described programmable controller PLC and computing machine.
Principle of work of the present utility model is:
Whether first is used for perception workpiece to level sensor puts in place, its perceptual signal is admitted to programmable controller PLC, programmable controller PLC triggers Machine Vision Inspecting System after receiving this perceptual signal and takes pictures to workpiece, Machine Vision Inspecting System is by the pixel distribution of shooting image and brightness, the information such as color are transformed into digitized signal, again various computing is carried out to extract clarification of objective to these signals, as the linearity in form and position tolerance, flatness, the depth of parallelism and verticality, extract result and be admitted to computing machine, contrasted by computing machine and detect, judge whether workpiece form and position tolerance meets the demands.When result is qualified, computing machine sends a signal to programmable controller PLC, and programmable controller PLC does not make action to workpiece, and workpiece continues to move ahead on a production line; When the testing result that programmable controller PLC receives is defective, and after receiving second to the perceptual signal that puts in place of level sensor, drive pusher driver by programmable controller PLC, pusher driver control pusher makes underproof finished workpart be pushed to defective district from production line.
