Description

Defect detecting device based on motor copper bar burr growth district
Technical field
The utility model relates to a kind of defect detecting devices based on motor copper bar burr growth district, belong to quality testing Field.
Background technique
Motor is a kind of a kind of calutron that the foundation law of electromagnetic induction is realized electric energy conversion or transmitted, and by rotor and is determined Sub- two parts composition.Rotor position applied to the large-size machine under industrial environment, which is set up, counts into special flute profile, then will be electric Machine copper bar wraps in one layer of insulating film embedded groove, then end ring and copper bar is welded into one, and forms rotor structure.In order to control motor Temperature obtains good heat dissipation, and the copper bar as rotor wire is generally required in some holes of intermediate cut, but is also generated simultaneously Burr has buried very big hidden danger for motor.
The detection device of image background difference is mostly used to carry out burr detection to motor copper bar in industrial application at present, i.e., Using the smoothness of local gray level and change of gradient information adjustment different zones in image, obtains background image and will locate in advance Image after reason carries out difference operation with it, obtains defect image.But the operation in entire image of this method, and can be indistinguishably Device to hole head position scratch, abrasion the defects of detected, weaken burr detection accuracy.In addition, the inspection based on background difference It is poor to survey device versatility, high-precision detection effectively can not be carried out to motor copper bar various types burr, to a large amount of electricity During machine copper bar image is actually detected, erroneous detection easily occurs, brings biggish trouble to work on the spot.
Summary of the invention
The purpose of the utility model is to provide a kind of defect detecting device based on motor copper bar burr growth district, to It solves the above problems.
A kind of defect detecting device based on motor copper bar burr growth district, including CCD industrial camera, Image Acquisition Card, electronic control translation stage, precision stage, articles holding table, hood, manually controls instrument, position sensor and computer at LED light source.
The position sensor is set to workpiece position to be detected, triggers CCD industry camera shooting by generating pulse signal Machine work;The LED light source diffuses illumination using the low angle of ring structure, is set to below CCD industrial camera;CCD It is provided with precision stage below industrial camera, the copper bar workpiece with hole slot is placed on the articles holding table of precision stage And speed and the track of articles holding table are controlled by electronic control translation stage;Image pick-up card is connected with CCD industrial camera by buttock line And and computer communication.
The CCD industrial camera is disposed vertically right above workpiece position to be detected, and CCD industrial camera uses Hood shielding environment shadow is rung, and camera lens visual field is covered in the articles holding table center of precision stage, can be once to 2 copper bars Workpiece hole slot is shot.
The collected copper bar image of image pick-up card is analyzed and is determined by the computer, and shows in computer Show the morphological feature and position coordinates of detected burr, be stored in system, completes the detection of motor copper bar burr.
Detailed description of the invention
Fig. 1 is the defect detecting device figure provided by the utility model based on motor copper bar burr growth district;
Fig. 2 is the utility model embodiment test object motor copper bar figure.
In figure: 1- electronic control translation stage, 2-LED light source, 3-CCD industrial camera, 4- image pick-up card, 5- computer, 6- Copper bar workpiece, 7- precision stage, 8- articles holding table, 9- position sensor, 10- hood, 11- manually control instrument.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the defect detecting device based on motor copper bar burr growth district is by CCD industrial camera 3, image Capture card 4, electronic control translation stage 1, precision stage 7, articles holding table 8, hood 10, manually controls instrument 11, position spy at LED light source 2 It surveys device 9 and computer 5 forms.
The CCD industrial camera 3 is rung using 10 shielding environment shadow of hood, is disposed vertically in workpiece location to be checked Right above setting, camera lens visual field is covered in 8 center of articles holding table of precision stage 7, can be once to 26 hole slots of copper bar workpiece It is shot.
The LED light source 2 is set to 3 lower section of CCD industrial camera, in order not to cause the plate face of copper bar workpiece 6 reflective, Lighting method is diffused using the low angle of ring structure.
Described manually controls instrument 11 at setting copper bar workpiece position to be detected, is corrected by manual fine-tuning, to guarantee The quality of acquired image.
In defect inspection process, copper bar workpiece 6 to be detected is placed on the articles holding table 8 of precision stage 7, by automatically controlled Speed and track is arranged in translation stage 1, and the copper bar workpiece 6 controlled on articles holding table 8 moves to position to be detected, at this time position sensor 9, which issue pulse signal control industrial camera 3, works, the image processing module for acquiring copper bar image and being transmitted in computer 5 It analyzes it and determines, detect burr.
