And top plate 230, the first panel 210 and second panel 220 are fixed on the two sides of 110 transmission rail of roll shaft.
Image recognition sensor 30 is fixedly installed on the top plate 230 of bracket 20, the figure of sensor head (camera) shooting
After passing through camera lens, electric signal is converted by light receiving element (CMOS), then according in the light receiving element pixel points
The light and shade and deep or light information matched, the brightness and shape of discrimination objective identify the profile of test product to distinguish test product
Whether direction is wrong, it is preferable that the image recognition sensor of Keyemce, a sensor can track multiple targets and be examined
It surveys, judges whether test product has the direction of missing and test product whether wrong rapidly.
Control unit 40 is fixedly installed on the top plate 230 of bracket 20, described image identification sensor 30 and its electrical property
Connection, described control unit 40 is for data collection and processing and the operation of man-machine interface.
Laser sensor 50 is fixedly installed on the edge in the outside of the top plate 230 of bracket 20, the laser sensor 50
Sensor head direction straight down and perpendicular to 110 transmission rail of roll shaft, the laser sensor 50 is to be detected for detecting
Whether product enters detection zone, is electrically connected with control unit 40, will after laser sensor 50 detects product to be detected
Signal is driven to control unit 40, and control unit 40 transmits a signal to image recognition sensor 30, image recognition sensor again
30 prepare to start to start；If laser sensor 50 does not detect product to be detected, signal is transmitted to control unit 40, is controlled
Signal is sent to laser sensor 50 by unit 40 again, and laser sensor 50 continues to detect.
In the present embodiment, that fixes in the first panel 210 or second panel 220 is equipped with robotic device 60, institute
It states robotic device 60 and control unit 40 is electrically connected, can will believe after image recognition sensor 30 detects substandard product
Number send control unit 40 to, control unit 40 can send this signal to robotic device 60 at once, and robotic device 60 connects
It receives this signal unqualified label is affixed on detected substandard product, and this substandard product is used to the crawl of holding type
Mode is placed into specified region, distinguishes processing, and the material of the carrier 710 in the present embodiment is PET or steel disc carrier,
PET carrier cost is relatively low but to be disposable, and the material is soft by PET, steel disc carrier higher cost can still recycle again
It utilizing, material is harder, if carrier 710 is easy to be detached from by the product in external force carrier, therefore the selection support of robotic device 60
The type mode of holding take out carrier be it is most safe, to carrier injure least way.
In the present embodiment, described control unit 40 and roll shaft transmission device 10 are electrically connected, and described control unit 40 is found
Roll shaft transmitting device 10 closes power supply when detection occurs abnormal, and roll shaft transmitting device 10 is out of service, prevents from going out at detection zone
Now abnormal, roll shaft transmitting device 10 is also continuing to run.
In the present embodiment, such as Fig. 6, a kind of detection method of product missing includes the following steps:
S1, it is debugged, by the threshold value set to control unit 40, or has the product that detected and will detect before
Threshold value keep records of, control unit 40 sends this threshold value to image recognition sensor 30；
S2, laser sensor 50 judge whether there is product to be detected and enter detection zone, when laser sensor 50 detects
Control unit 40 is transmitted a signal to laser sensor 50 when testing product enters detection zone is needed, control unit 40 will be believed
Number image recognition sensor 30 is sent to, into next step S3；When laser sensor 50 has not detected production to be detected
Laser sensor 50 sends this signal to control unit 40 when product enter detection zone, and control unit 40 continues to pass this signal
Laser sensor 50 is given, step S2 is continued；
S3, image recognition sensor 30 carry out information collection to product, and information comparison handles and sends comparison result to
Control unit 40, control unit 40 receive information, if control unit 40 is not made a response the result is that product testing is qualified；
If then control unit 40 communicates information to robotic device 60 the result is that product testing is unqualified, robotic device 60 will
Unqualified label is attached on substandard product, and then robotic device 60, which picks up substandard product, is placed on specified region；
S4, the detection for continuing next product.
In conclusion a kind of product lacks device, roll shaft transmitting device 10 transmits product to be detected, and laser sensor 50 is sentenced
Whether the product to be detected that breaks has into detection zone, and image recognition sensor 30 detect to product and feedback result, mechanical
Hand equipment 60 is identified and distinguishes to substandard product, and above-mentioned these are required by control unit 40, by control unit
40 order transmission instruction come the number of hair, it follows that, the said goods lack detection device and replace human eye detection, not only increase production
Efficiency and reduction cost of labor.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
