Description
Technical field
The present invention relates to a kind of Workpiece detecting device of use image recognition technology, specially a kind of rotary work piece detection dress
Put.
Background technology
In parts processing industry, need to be tested to whether part satisfies the criteria before part dispatches from the factory, as image is known
The development of other technology, automation piece test technology is ripe all the more, and the speed of inspection and the precision of inspection are all higher than desk checking,
Increasing enterprise checks workpiece using image recognition technology.
When workpiece is detected using image recognition technology, generally at least the six of workpiece faces are shot, so
The image for shooting is tested afterwards.Therefore image recognition needs the surface information from multiple angle acquisition parts, it means that
Need to set multiple cameras from multiple angle shot workpiece, or only one of which camera but need automation equipment to overturn workpiece,
Then camera shoots each face of workpiece.
Need to detect rotary work piece now, it is required if adopting two kinds of above-mentioned check systems carries out Workpiece inspection
Equipment and the equal too complex of flow, the time of inspection are also more long.Company considers that the characteristic that can be rotated using rotary work piece is carried out
Shoot, the carrying out for setting rotary work piece of the camera from top to rolling shoots.Then returned using image separation technique intercepts
Change a job the image of part near top, defects detection then is carried out to the parts of images.Prior art problem demanding prompt solution is：Inspection
The result of survey is not reaching to the precision in anticipation, it is impossible to adapt to high-precision detection.
The content of the invention
The invention is intended to provide a kind of high-precision detection device suitable for rotary work piece.
The present invention provides base case：Rotary work piece detection means, including inlet, lubricating substance part, outlet, promotion work
The workpiece revolving meber and camera of part revolution, the inlet connect lubricating substance part, and lubricating substance part connects outlet, wherein, the cunning
The working face of materials and parts is arc surface, and also including the camera revolving meber for promoting camera to turn round, the workpiece revolving meber and camera are returned
Turn part the centre of gyration be respectively positioned on lubricating substance part arc surface circle centre position, the angular speed phase of workpiece revolving meber and camera revolving meber
Together.
One by one be input into rotary work piece by inlet, the arc surface of lubricating substance part steady rolling for rotary work piece is provided, outlet
Rotary work piece is exported, workpiece revolving meber promotes rotary work piece in being rolled on lubricating substance part, and camera is at the different moment in rolling
Rotary work piece shot, so as to obtain the complete image information of side surface of workpiece, it is same that cylindrical workpiece is rolled on arc surface
When, camera revolving meber also promotes rotary work piece camera to be turned round, and workpiece revolution is respectively positioned on cunning with the centre of gyration of camera revolution
The circle centre position of the arc surface of materials and parts, and workpiece revolving meber is identical with the angular speed of camera revolving meber, this causes camera with revolution work
Part energy synchronous revolving.
Operation principle：One by one be input into rotary work piece by inlet, and workpiece revolving meber promotes rotary work piece to prolong arc surface rolling,
Camera revolving meber promotes camera revolution, because the pivot of the two is identical identical with revolution angular speed therefore the two revolves for synchronous
Turn, additionally due to workpiece be rotary work piece, rotary work piece by workpiece revolving meber promote prolong the centre of gyration rotation constantly itself
Can be rolled relative to the working face of lubricating substance part carries out rotation, now with the phase chance of rotary work piece synchronous revolving when different
The rotary work piece in rolling is shot, so as to obtain the complete side image of rotary work piece.
Compared with prior art, the advantage of this programme is：1., relative to existing image detection device, this programme is to rolling
Rotary work piece side in dynamic is shot, and only can just can be completed to rotary work piece with a camera, simple transmission device
Side multi-angled shooting.
1. camera and rotary work piece be with the same centre of gyration, with angular speed synchronous revolving, so even what camera shot
It is to prolong rotary work piece in centre of gyration revolution, the rotary work piece for camera is equal to during shooting and is not moved, therefore
The rotary work piece image of shooting also will not such as moving camera shooting when the ghost image that produces, additionally due to being sync pulse jamming so will not be because
Causing rotary work piece surface reflection brightness change or image for the angle change for shooting has missing, in sum, the present invention
The precision of images of shooting is high, and due to image recognition technology is based on image, so improving the precision of images can just improve workpiece
Accuracy of detection.
