In the related art, the filter tip of a cigarette is one type of filter rod, and in the cigarette manufacturing process, laser drilling of the filter tip is an important processing step.

The filter tip laser drilling machine mainly comprises a laser drilling automatic following system, a contact of a potential sensor, a laser drilling motion system and the like. The process has high processing precision and can refine the ultra-micropores to 0.001 mm. However, for various reasons, the quality of the perforation may be affected and therefore the detection of laser perforation of the filter is of paramount importance.

Alternative embodiments of the present disclosure are described in detail below with reference to the drawings.

The disclosure provides a method for detecting a filter rod after laser drilling, aiming at the filter rod after laser drilling. The present disclosure is generally applicable to laser-drilling detection processes for filter sticks, and is particularly applicable to laser-drilling detection of filters for cigarettes.

Fig. 1 shows a flow chart of an on-line detection method of a laser-perforated filter rod according to an embodiment of the disclosure.

As shown in fig. 1, according to a specific embodiment of the present disclosure, in one aspect, an on-line detection method of a laser-perforated filter rod is provided, which at least may include the following steps:

And S100, adding identification to the filter stick to be tested based on the number.

S200, simultaneously collecting images of the filter sticks to be tested with different marks at a plurality of positions to obtain a plurality of groups of image data.

And S300, performing laser hole detection on the plurality of groups of image data to obtain a detection result.

Wherein the plurality of sets of image data may comprise images of the filter rod to be tested with all the identifications. The online detection method of the laser-perforated filter rod disclosed by the disclosure can detect different filter rods on the conveying mechanism 100 at different positions simultaneously by carrying out identification classification according to the number of cigarettes. According to the detection result, unqualified cigarettes can be removed or subjected to other treatments, so that the production efficiency and the product quality are improved. The online detection method of the laser drilling filter stick can not only improve the detection accuracy and speed, but also meet the logic control requirements of a high-speed cigarette wrapping machine and a high-speed image picking camera.

Wherein, in step S100, in some embodiments, the step S100 may include: and adding odd-even identification to the filter stick to be tested based on the odd-even number. In some embodiments, the method for online detection of a laser-perforated filter rod of the present disclosure may employ a high-performance encoder, where the high-performance encoder is simultaneously linked with the controller and the transmission mechanism 100, and for parity determination of the filter rod to be detected, the position information of the filter rod to be detected may be represented by binary encoding. Assuming that the position information of the filter rod to be measured is represented by 8-bit binary numbers, each bit corresponds to a passing position of one filter rod to be measured, wherein the 1 st bit represents the 1 st position, the 2 nd bit represents the 2 nd position, and so on. The parity check method of binary coding is a common strategy for checking the number of "1" s in binary data, and is mainly used for judging whether a number is odd or even. Similar methods may also be employed in the high performance encoder to determine the odd and even logic control of the filter rod under test. When the hub wheel of the filter rod channel to be tested rotates, the high-performance encoder outputs an 8-bit binary number which represents the current 8 position information of the filter rod to be tested. We can input these 8-bit binary numbers into the parity check logic control module to make parity decisions.

Wherein, in step S200, in some embodiments, the step S200 may include: collecting images of the filter sticks to be tested with odd marks at a first position to obtain first image data; and acquiring images of the filter sticks to be detected with even marks at a second position to obtain second image data. At the first image capturing device 210 and the second image capturing device 220, the transmission mechanism 100 is configured to receive the logic signal of the parity determination of the high-performance encoder, and determine whether the current cigarette is odd or even according to the logic signal. Meanwhile, the conveying mechanism 100 may send a drawing instruction to the corresponding first image capturing device 210 or the second image capturing device 220. The specific implementation is as follows: the high performance encoder outputs the parity logical signal to the transmission mechanism 100. After receiving the logic signal, the conveying mechanism 100 determines whether the current cigarette is odd or even according to the signal. According to the judgment result, the transmission mechanism 100 transmits the image capturing instruction of the corresponding odd-numbered or even-numbered camera to the corresponding image capturing device. And after receiving the image acquisition instruction, the image acquisition device performs image acquisition operation. The image acquisition device acquires an image of the object to be detected and transmits image data to the detection unit.

Wherein, in step S300, in some embodiments, the step S300 may include: and respectively carrying out laser hole detection on the first image data and the second image data to obtain detection results. In the actual process, the detection unit performs preprocessing on the multiple groups of image data, including operations such as image denoising and image enhancement, so as to improve the quality and recognition accuracy of the image. And the detection unit detects the laser holes on the preprocessed image based on a preset laser hole detection algorithm. The laser hole detection algorithm may include edge detection, shape analysis, etc. steps to determine the location and shape of the laser hole.

In some embodiments, the method for on-line detection of a laser-perforated filter rod may further comprise the steps of:

S400, judging whether the detection result is qualified or not; and when the detection result is unqualified, rejecting the unqualified filter stick. In an alternative embodiment, when the detection result is not qualified, the identification of the unqualified filter rod is recorded, and when the rejection mechanism 300 identifies the unqualified identification, the corresponding filter rod is rejected. Specifically, according to the laser hole detection result, the judgment unit performs logic judgment. The laser holes can be judged according to the number, the positions, the shapes and other characteristics of the laser holes. For example, if two rows of laser holes are detected and the shapes and positions of the two rows of laser holes meet preset conditions, judging the object to be detected as qualified; if the number or the shape of the detected laser holes does not meet the preset condition, judging that the object to be detected is unqualified.

And outputting corresponding instructions or signals by the industrial personal computer according to the logic judgment result. For example, if the judgment result is qualified, outputting a signal to the next process or equipment; if the judging result is unqualified, outputting a signal to a rejecting device, and rejecting the unqualified object to be detected.

In some embodiments, numbering filter rods to be tested based on number may include: and adding odd-even identification to the filter stick to be tested based on the odd-even number.

In some embodiments, acquiring images of the filter rod to be tested at multiple locations simultaneously based on the identification may include: collecting images of the filter sticks to be tested with odd marks at a first position to obtain first image data; and acquiring images of the filter sticks to be detected with even marks at a second position to obtain second image data.

In some embodiments, laser hole detection of the plurality of sets of image data may include: and respectively carrying out laser hole detection on the first image data and the second image data to obtain detection results.

In some embodiments, the method for on-line detection of a laser-perforated filter rod may further comprise: judging whether the detection result is qualified or not; and when the detection result is unqualified, rejecting the unqualified filter stick.
