Technical Field

[0001] This specification relates to data processing technology in one or more embodiments, and more particularly to a method, apparatus and electronic device for engraving control of cigar wrappers. Background Technology

[0002] As cigar brands offer increasingly diverse product features and more individual cigar labels are being applied, the amount of tobacco obscured is growing, making it difficult to judge product quality directly from the appearance. Therefore, some cigar manufacturers are considering laser engraving to directly add patterns, text, and serial numbers to the cigar wrapper, replacing various labels and reducing the number of labels and obscured tobacco. However, cigar wrappers need to be extremely thin, generally no more than 1mm thick. Currently, there is no precise method to control the laser engraving process, making it easy for excessive laser power to damage the wrapper, producing a protein odor and affecting product quality.

Therefore, this application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then this application should also be considered to include embodiments containing one or more other possible combinations of A, B, C, and D, even if such embodiments are not explicitly described in the following text.

Furthermore, features described with respect to some examples may be combined into other examples.

[0022] See Figure 1 , Figure 1 This is a flowchart illustrating a method for controlling the engraving of a cigar wrapper according to an embodiment of this application. In this embodiment, the method includes: S101. Obtain the wrapper information and carving content information of the target cigar to be carved, and determine the laser power range based on the wrapper information.

[0023] The information regarding the eggplant wrapper includes the wrapper material and the wrapper thickness.

[0024] The entity executing this application may be a cloud server.

[0025] In this embodiment of the specification, the worker sends the cigar type information of the target cigar to be laser-engraved to a cloud server. The cloud server can then query the cigar database based on the cigar type information to obtain the wrapper information and engraving content information of the target cigar. The wrapper information describes the wrapper material and thickness used for that type of cigar, while the engraving content information describes the pattern / text / symbol to be engraved on the wrapper. Next, the cloud server can determine the strength and deformation of the wrapper based on the wrapper information, thereby determining the stress range within which irreversible deformation of the wrapper is desired without causing it to break, and thus determining the laser power range.

[0026] There are many ways to determine the laser power range using eggplant wrapper information. For example, a material strength database can be pre-set in a cloud server. This database stores data on the structural deformation changes of eggplant wrappers of different thicknesses and materials under different energy levels, as determined by testers. The cloud server queries this material strength database using the eggplant wrapper information to determine the energy intensity range from leaving an imprint on the eggplant wrapper (i.e., causing irreversible deformation) to just causing it to break, and then determines the laser power range based on the correspondence between energy intensity and laser power. Alternatively, testers can directly construct a mapping database representing the relationship between eggplant wrapper information and laser power range based on the aforementioned test data. The cloud server only needs to query this mapping database using the eggplant wrapper information to determine the laser power range. Other implementation methods are also possible in other embodiments.

[0027] In one possible implementation, determining the laser power range based on the eggplant wrapper information includes: Based on the wrapper information, the wrapper strength information of the target cigar is determined, the initial deformation strength and the wrapper breakage strength of the wrapper are determined according to the wrapper strength information, and the laser power range is determined according to the initial deformation strength and the wrapper breakage strength of the wrapper.

[0028] In the embodiments of this specification, wrappers of different materials and thicknesses correspond to different structural strengths, i.e., wrapper strength information. This can be determined in advance through testing various wrappers. Since tobacco factories generally use a few fixed types and parameters of wrappers, they do not specifically set different parameters for wrappers when the type of cigar remains unchanged. Therefore, the total amount of data to be tested is not particularly large. The wrapper strength information can be a set of data representing the change in structural strength of the wrapper after being subjected to external forces of different energy intensities. Through the wrapper strength information, the cloud server can determine the initial deformation strength of the wrapper when it has just undergone irreversible deformation (i.e., the wrapper can leave a mark) and the damage strength of the wrapper when it has just broken. The intensity range corresponding to these two intensities is the range of laser intensity that can be used when laser engraving the wrapper of the target cigar. Therefore, the cloud server will determine the range of laser power that the laser can output based on this intensity range and the calculation relationship between laser intensity and power.

[0029] S102. Based on the engraving content information, determine the engraving path of the laser emission object, calculate the path area ratio of the judgment area corresponding to each engraving point in the engraving path, and determine the laser power corresponding to each engraving point according to the path area ratio and the laser power range.

[0030] In the embodiments of this specification, the cloud server first determines the engraving path of the laser-emitting object to be laser-engraved based on the engraving content information. The laser-emitting object can be a laser emitter or a laser-emitting device equipped with a laser emitter. The engraving path can be determined by having a pre-set engraving path directly in the engraving content information, or by the cloud server autonomously planning the shortest total path after determining the content to be engraved, or by other feasible implementation methods. The engraving path can be refined into individual engraving points. Ideally, to ensure the engraving effect, the laser power should be as high as possible without damaging the outer skin. However, due to the different engraving content, some areas may require repeated engraving, or more complex engraving may be required in a small local area. In these cases, the structural strength or overall stress of that area is more prone to change due to higher engraving density or continuous laser exposure, making it more susceptible to breakage. Therefore, in practice, the cloud server will adjust the laser power output to different engraving points according to the different engraving content, rather than always maintaining the maximum power within the laser power range for engraving.

[0031] Specifically, a rule for generating the judgment area can be pre-set. For example, a circular area with a specified radius centered on the carving point can be used as the judgment area. The cloud server will determine the judgment area corresponding to each carving point and, based on the carving path, determine the path area ratio within each judgment area. The higher the path area ratio, the more fragile the area is considered, and the lower the laser power should be output. Finally, the cloud server will determine the laser power corresponding to each carving point based on the path area ratio and the laser power range. As an example, the laser power can be determined by proportionally selecting corresponding numerical points within the laser power range based on the path area ratio, or by pre-setting the correspondence between the path area ratio and the range selection ratio, and determining the specific laser power within the laser power range based on this correspondence, or by weighted calculation using the median value of the path area ratio and the laser power range.

[0032] In one possible implementation, calculating the path area percentage within the judgment area corresponding to each carving point in the carving path includes: Determine the moving speed of the laser-emitting object, and determine the judgment area corresponding to the engraving point in the engraving path based on the moving speed. The moving speed is inversely proportional to the area of ​​the judgment area. Calculate the path area percentage for each of the judgment regions.

[0033] In the embodiments of this specification, considering that the laser-emitting object may be set to different moving speeds depending on the actual situation, even if the laser power is the same, the time that the eggplant wrapper per unit area is exposed to the laser will be different at different speeds. To avoid damage to the eggplant wrapper caused by different moving speeds, the cloud server determines the area of ​​the judgment region based on the moving speed. The slower the speed, the longer the eggplant wrapper per unit area is exposed to the laser, and the more easily the eggplant wrapper is damaged. Therefore, the area of ​​the judgment region is set to be larger, so that more non-carved parts are covered within the region, making the path area ratio relatively smaller, and thus the laser power can be selected to be smaller, thereby avoiding damage to the eggplant wrapper.

[0034] In one possible implementation, determining the laser power corresponding to each of the engraving points based on the path area ratio and the laser power range includes: The laser power selection ratio is determined based on the path area ratio, and the laser power corresponding to each engraving point is determined within the laser power range based on the laser power selection ratio.

[0035] In the embodiments of this specification, the cloud server may have a pre-set conversion relationship between path area ratio and laser power selection ratio. After determining the path area ratio, the laser power selection ratio can be determined according to the conversion relationship. Then, the cloud server will select the corresponding numerical point within the laser power range as the laser power for the engraving point according to the laser power selection ratio.

[0036] As an example, assuming the laser power range is [40W, 60W] and the laser power selection ratio is 40%, the final determined laser power is 48W.

[0037] In one possible implementation, determining the laser power selection ratio based on the path area ratio includes: The number of overlapping nodes in the judgment area is determined, and the laser power selection ratio is obtained by weighting the path area ratio and the number of nodes.

[0038] In the embodiments of this specification, in order to engrave different patterns, the engraving path may have repeated parts, that is, some paths may intersect, resulting in overlapping nodes. In this case, the eggplant wrapper is more likely to be damaged due to repeated laser impact in localized areas, and the laser power should be appropriately reduced. Therefore, the cloud server will also determine the number of nodes with overlapping paths within the judgment area, and set different weights for the path area ratio and the number of nodes, respectively. The laser power selection ratio is obtained by weighting the path area ratio and the number of nodes. Among them, the weight corresponding to the number of nodes is a negative weight.

[0039] S103. Construct a laser power control curve based on the position sequence and the laser power of each laser, and control the emission power of the laser emitting object on the engraving path according to the laser power control curve.

[0040] In the embodiments described in this specification, a laser power control curve can be constructed by connecting the laser powers according to the positional sequence of each engraving point in the engraving path. During the laser engraving process according to the engraving path, the cloud server continuously and dynamically adjusts the emission power of the laser emission object based on the laser power control curve to control the laser intensity emitted to various positions on the eggplant wrapper, thereby ensuring the engraving effect of the eggplant wrapper as much as possible while avoiding damage to the eggplant wrapper.

[0041] In one possible implementation, controlling the emission power of the laser emitting object along the engraving path according to the laser power control curve includes: The adjustment time is determined based on the moving speed of the laser emitting object. The laser power control curve is shifted forward by the adjustment time in the time direction, and the emission power of the laser emitting object on the engraving path is controlled according to the adjusted laser power control curve.

[0042] In the embodiments described in this specification, considering that in reality, the laser-emitting object moves at a certain speed, and there is a certain response time between continuously sending adjustment commands according to the laser power control curve and the laser-emitting object responding to the adjustment commands and changing the emission power, if the power control is directly performed according to the laser power control curve, the laser intensity hitting each engraving point will inevitably deviate from the expectation, and the faster the movement speed, the greater the deviation, which may even increase the risk of shell breakage in some cases. Therefore, the cloud server determines a certain lead time, i.e., adjustment duration, based on the movement speed of the laser-emitting object, and adjusts the laser power control curve accordingly. This ensures that the adjusted curve takes into account the response deviation caused by the movement speed, thereby sending the corresponding adjustment commands in advance to guarantee the final engraving effect. The mapping relationship between the movement speed and the adjustment duration can be set by the operator based on prior simulation test data and human experience.

[0043] In one possible implementation, the method further includes: After detecting the completion of the engraving, a transmission power curve is generated based on all the aforementioned transmission powers; By comparing the emission power curve and the laser power control curve, the control error is determined.

[0044] In the embodiments described in this specification, after completing one engraving according to the engraving path, the cloud server will also construct an emission power curve based on the actual emission power and compare it with the laser power control curve to determine whether there are still control errors. If there are control errors, the cloud server will consider the control errors in subsequent control processes and further adjust the laser power control curve in subsequent engraving processes.
