Phenomenon causes unstable product quality；3) examination criteria disunity.Due to different people to the criterion of the color depth in the presence of a
Body difference causes the result of detection to have differences；4) detection controlling cycle is long.It is per minute to give birth to by taking crown cork produces as an example
2600 bottle caps are produced, average 43.4 bottle caps per second under such high speed, can not manually carry out on-line checking, and once give birth to
There is product quality deviation in producing line, can not adjust in time, it will has a large amount of defect ware to be produced, causes to waste.
Invention content
The purpose of the present invention is to overcome the deficiency in the prior art, especially solves existing traditional artificial detection bottle cap quality inspection
The problems such as survey method speed is slow, efficiency is low, detection quality is unstable, detection controlling cycle is long.One kind is provided to regard based on computer
Feel the bottle cap automatic detection device for quality of control, which uses rotatable platform and speed regulating motor, and automatic rotary bottle cover, which enters, to be taken the photograph
Camera is taken pictures range, and automatic camera is realized, and determine that the time of delay is long according to the movement law of bottle cap by sensor sensing
It is short, when bottle cap reaches viewing field of camera center, camera shutter is opened, captures bottle cap image, after image acquisition, carries out the place of image
Reason finds out the center of bottle cap image.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
It is described the purpose of the present invention is to provide a kind of bottle cap automatic detection device for quality based on computer vision control
Device includes control module, image collection module, mechanical movement module and workbench；The control module include control unit and

Device, camera, light source are connected, and the infrared transmitter is located at the rotating platform side, and the infrared remote receiver is located at rotary flat
Platform opposite side, the camera and light source are located on stent, and the governor is connected with speed regulating motor, for adjusting motor speed,
The speed regulating motor is connected with swivel bearing, and the center of the rotating platform is connected with swivel bearing, and the swivel bearing is from branch
The center of support platform passes through, and the stent is located in support platform, and the conveyer belt is connected with rotating platform.
The speed regulating motor driving swivel bearing rotation, swivel bearing drives rotating platform rotation, thus will be on conveyer belt
Bottle cap be sent on rotating platform, when bottle cap pass through infrared remote receiver when, positioned at the infrared transmitter of rotating platform opposite side
The infrared signal of transmitting is shielded by bottle cap, and infrared remote receiver can not receive infrared signal, and described control unit receives at this time
The signal of infrared remote receiver, control unit, which is sent, opens photographing signals to camera and light source, and unlatching light source opens camera and takes pictures,
Photo is sent to control unit by camera, and control unit send photo to host computer, will accidentally after host computer handles image
Difference feeds back to control unit and carries out accurate control adjustment.
The present invention has following advantageous effect compared with prior art：
The present invention program utilizes image processing techniques, when bottle cap passes through infrared remote receiver, positioned at rotating platform opposite side
Infrared transmitter transmitting infrared signal shielded by bottle cap, infrared remote receiver can not receive infrared signal, at this time the control
Unit processed receives the signal of infrared remote receiver, and control unit, which is sent, opens the automatic acquisition that photographing signals realize bottle cap photo,
It is sent into host computer and carries out quality testing, realize the automatic detection of bottle cap quality in high-speed motion.
