The photoelectric switch is arranged at the entrance of the conveyor belt, namely when the package enters the conveyor belt, the package can trigger the photoelectric switch, and the photoelectric switch generates a photoelectric trigger signal.
The industrial personal computer is provided with a plurality of kilomega network ports, a plurality of usb (Universal Serial Bus) interfaces, a win7 system and an i7 processor.
Referring to fig. 1, the six-sided camera may be embodied as:
the bottom surface is a line scan camera 110, supporting 8k high definition imaging.
Two sides 120: two 1200w pixel cameras +12mm lenses + light lights L1600W x 3.
The front and the back are: two 1200w pixel cameras +16mm lenses 130 (in the figure 130 is a combination of two 1200w pixel cameras +16mm lenses) + lamp 140L1600W × 4.
The top surface 150 is 3 500w cameras + strobe light source.
In practical implementation, the mounting sequence of the six cameras may be:
1. firstly, a top camera is installed, the camera and a stroboscopic light source are together, the distance between the camera lens and the belt surface is about 1750mm, and the distance between the camera and the camera is about 300 mm;
2. the distance from the center of the side camera to the photoelectric trigger horizontal distance is about 150 mm;
installation height of the left code reading camera a: the mounting height of the left code reading camera B is about 700mm from the flange surface of the camera A to the surface of the conveying line: the distance between the flange surface of the B camera and the code reading camera on the left side and the right side of the surface of the conveying line is about 400 mm: the distance between the flange surfaces of the two cameras is 2500 mm;
3. the front and back code reading cameras are arranged at the height: the distance between the camera flange surface and the surface of the conveying line is about 900mm
The distance between the front and the rear code reading cameras is as follows: 450mm
The distance between the flange surface of the front camera and the photoelectric trigger horizontal distance is as follows: about 1400mm
The distance between the flange surface of the rear camera and the photoelectric trigger horizontal distance is as follows: about 1700mm
4. Then, a bottom camera is installed, and the bottom camera is required to be installed between the two belts according to the situation of the site, namely below the gap between the two belts;
5. trigger lines of all cameras are connected together, trigger photoelectricity is installed according to the situation of a site, and all cameras work normally when the photoelectricity is debugged or not.
After the above-described mounting, a top view and a front view of the six-sided camera are formed as shown in fig. 1 and 2, respectively.
Of course, the above is exemplified by only using the mounting parameters of six cameras as the above parameters, and in actual implementation, the distance between the cameras may also be other values according to the actual application scenario, which is not limited in this embodiment.
In addition, the six-side code scanning system is exemplified to include the above components, and in practical implementation, the six-side code scanning system may further include a base for fixing the conveyor belt and the six-side camera, and a heat dissipation device for dissipating heat for the camera or the system. Of course, the system further includes a motor for driving the conveyor belt to move, which is not described herein again in this embodiment.
Referring to fig. 3, it shows a flowchart of a method for six-sided code scanning according to an embodiment of the present application, which may be used in the six-sided code scanning system according to the foregoing embodiment, as shown in fig. 3, the method includes:
In the moving direction of the conveyor belt, when the package moves to the position of the photoelectric switch, the photoelectric trigger switch can generate a photoelectric trigger signal, and the industrial personal computer controls the six-face camera to start photographing according to the photoelectric trigger signal.
Optionally, when the logistics single side of the package faces downward, the bottom camera located in the middle of the gap between the two sections of conveyor belts can start scanning, scan out data in a line and a row along with the movement of the package driven by the conveyor belts, and finally splice into a whole complete code scanning image; and if the single surface of the parcel in the logistics is not downward, the cameras on other surfaces can acquire image data by photographing.
The cameras on the bottom surface can be line scan cameras, the time from the beginning of image acquisition to the barcode output of a single line scan camera is 50ms to 300ms, the cameras on other surfaces can be area-array cameras, and the time from the beginning of image acquisition to the barcode output of a single area-array camera is 30-100 ms.
And step 302, outputting the bar code of the package according to the photographing result of the six-face camera.
After the photographing results of the cameras on the six surfaces are obtained, the industrial personal computer can output the bar code of the package according to the photographing results.
The barcode may be a two-dimensional code or a barcode, which is not limited in this embodiment.
In summary, when a parcel is in the conveyor belt, a six-face camera is used for photographing, and then the barcode of the parcel is output according to the photographing result of the six-face camera; the problems that manual bag turning and sorting needs to be carried out in the prior art, the sorting efficiency is low, and the sorting reliability is poor are solved; reached no matter parcel single face towards which direction, all can sweep the sign indicating number through six cameras and obtain the bar code, improved the effect of letter sorting efficiency and letter sorting reliability.
It should be added that, because the time for obtaining the image data by scanning with the line-scan camera is longer than the scanning time of each of the other surfaces, in order to avoid confusion of the received photographing results of each camera by the industrial personal computer, in actual implementation, step 302 may include:
firstly, screening a photographing result meeting a preset condition; the preset condition includes before the next generation of the photoelectric trigger signal and/or within a preset time threshold after the current generation of the photoelectric trigger signal.
By screening out the photographing result received before the photoelectric trigger signal is generated next time, the confusion of the information of the current package and the information of the next package in the conveyor belt is avoided.
Through screening out the photographing result within the preset time threshold after the photoelectric trigger signal is generated, the problem that the industrial personal computer cannot output the bar code of the package when no other packages exist for a long time is avoided.
And secondly, outputting the bar code of the package according to the screened photographing result.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
