Description

Technical Field

[0001] The present application relates to the technical field of cigarette laser coding, and in particular to a cigarette laser coding device with an automatic identification function. Background Art

[0002] As an advanced identification technology, laser coding devices are widely used in surface marking of cigarette boxes. Its main function is to non-contactly mark cigarette boxes with high-precision laser beams, and print clear codes, patterns or texts to facilitate subsequent traceability, identification and anti-counterfeiting. Laser coding technology, with its high efficiency, accuracy and permanence, has gradually become an important means of anti-counterfeiting identification of cigarette boxes, and can effectively prevent counterfeit and inferior products during the product circulation process.

[0003] The working process of the laser coding device includes several key components, usually including the laser emitter, the optical path adjustment system, the control system and the mobile platform. When working, the laser emitter emits a high-energy laser beam through the control system, and the optical path adjustment system guides the laser beam to focus on the surface of the cigarette box, generating a thermal effect to cause physical or chemical changes on the surface of the packaging material, thereby forming a lasting mark. The whole process does not require contact with the object, the mark is clear and wear-resistant, and it meets the needs of fast coding in high-speed production lines, and has efficient industrial application value.

[0004] In the process of laser code recognition, image recognition technology is usually used. However, under complex lighting conditions, such as when law enforcement agencies intercept and inspect cigarette boxes in transit at night, it is very difficult to identify the laser code on the surface of the cigarette box. At night or in low-light environments, insufficient light makes it difficult for the image recognition system to accurately capture the code information, resulting in large recognition errors and affecting law enforcement efficiency. In addition, the concave and convex feeling formed by the real laser code on the surface of the cigarette box is an important sign of its authenticity. However, the counterfeit code is only attached to the plastic surface, and image recognition technology is difficult to distinguish between the two. Therefore, in response to the needs of these special usage scenarios, it is urgent to develop an improved technology that can cope with complex environments and can be combined with tactile recognition to improve recognition accuracy. Summary of the invention

[0005] In order to accurately identify the laser coding on cigarette boxes in complex environments, the present application provides a cigarette laser coding device with an automatic recognition function.

[0006] The present application provides a cigarette laser coding device with automatic identification function, which adopts the following technical solution: A cigarette laser coding device with automatic identification function comprises a workbench, a conveyor belt is arranged on the workbench, and the workbench is sequentially provided with: A laser coding mechanism, used for performing laser coding on the surface of the cigarette box placed on the conveyor belt; A touch recognition mechanism is used to correct the placement of the cigarette box and to perform contact recognition of the laser code on the surface of the cigarette box; Sunshade, used to shield complex ambient light from the outside world; An image recognition mechanism is provided in the light shield, and the image recognition mechanism is used to adjust the light intensity according to the color depth of the surface of the cigarette box entering the light shield, and is used to perform image recognition on the laser code on the surface of the cigarette box; A material discharging mechanism, used for classifying and discharging qualified and unqualified cigarette boxes identified by the touch recognition mechanism and the image recognition mechanism; When the touch recognition mechanism recognizes that the laser code on the surface of the cigarette box is false, the image recognition mechanism does not work, and the unloading mechanism unloads the cigarette box recognized as false into the unqualified area; When the touch recognition mechanism recognizes that the laser coding on the surface of the cigarette box is true, the image recognition mechanism recognizes the cigarette box and adjusts the light intensity in the light shield, and recognizes the laser coding on the surface of the cigarette box, and the feeding mechanism feeds the cigarette box to the corresponding area according to the recognition result.

[0007] By adopting the above technical scheme, the laser coding mechanism can perform laser coding on the surface of the cigarette box. When it is necessary to inspect the surface of the cigarette box after laser coding or to inspect other cigarette boxes, the other cigarette boxes here are suitable for law enforcement inspections or inspections in complex environments: when the touch recognition mechanism recognizes that the laser coding on the surface of the cigarette box is false, the image recognition mechanism does not work, and the unloading mechanism unloads the cigarette box to the unqualified area; when the touch recognition mechanism recognizes that the laser coding on the surface of the cigarette box is true, the image recognition mechanism recognizes the cigarette box and adjusts the light intensity in the light shield, and recognizes the laser coding on the surface of the cigarette box, and the unloading mechanism unloads the cigarette box to the corresponding area according to the recognition result.

[0008] Optionally, the touch recognition mechanism includes a position adjustment component for adjusting the placement position and angle of the cigarette box placed on the conveyor belt, and a touch component for touch recognition of the laser coding on the surface of the cigarette box adjusted by the position adjustment component.

[0009] By adopting the above technical solution, when it is needed to be applied in scenarios such as law enforcement inspections, the cigarette boxes are placed on the conveyor belt one by one, the position adjustment component will adjust the placement angle and position of the placed cigarette boxes, and then the touch component will perform contact recognition on the laser code on the upper surface of the adjusted cigarette box to determine the authenticity of the laser code on the cigarette box, thereby seizing fake cigarettes and punishing those who sell fake cigarettes.

[0010] Optionally, the position adjustment component includes a screw rod, a support rod, an elastic telescopic rod and an adjustment wheel, the screw rod is installed above the conveyor belt, and the touch component can drive the screw rod to rotate when it is actuated, two support rods are provided, the two support rods are respectively sleeved on the screw rod, and the screw rod and the two support rods have opposite thread rotation directions; The elastic telescopic rod and the adjusting wheel are provided in multiple groups, and the elastic telescopic rods and the adjusting wheels on the two support rods correspond to each other one by one. The elastic telescopic rod is installed at one end of the support rod away from the screw rod, and the adjusting wheel is rotatably installed at one end of the elastic telescopic rod away from the support rod.

[0011] By adopting the above technical solution, when the cigarette box moves to the bottom of the touch assembly, the conveyor belt is suspended, the touch assembly drives the screw to rotate, and the screw drives the two support rods to move in a direction close to each other, so that the two support rods drive the two rows of adjustment wheels to move to the two sides of the cigarette box. When the two rows of adjustment wheels contact the side wall of the cigarette box, the elastic telescopic rod will shrink. When it shrinks to a certain extent, the elastic telescopic rod will react to the side of the cigarette box to adjust the position of the cigarette box. When the cigarette box is adjusted, the touch assembly will touch and identify the laser code on the upper surface of the cigarette box.

[0012] Optionally, the touch assembly includes a first telescopic member, a connecting rod, a mounting plate and a capacitive touch sensor, the first telescopic member is installed above the conveyor belt, the connecting rod is coaxially fixed with the telescopic end of the first telescopic member, the mounting plate is fixed to the end of the connecting rod away from the first telescopic member, and the capacitive touch sensor is installed on a side of the mounting plate away from the connecting rod; A rack is fixed on the connecting rod along the length direction, and a gear meshing with the connecting rod is correspondingly arranged on the screw rod. When the first telescopic member is extended, the screw rod can drive the adjusting wheels to move in a direction close to each other.

[0013] By adopting the above technical solution, after the two rows of adjustment wheels adjust the position of the cigarette box, the first telescopic member continues to extend, and drives the mounting plate to move toward the upper surface of the cigarette box through the connecting rod, so that the capacitive touch sensor finally contacts the upper surface of the cigarette box, thereby performing contact recognition of the laser code on the cigarette box: If it is detected that there is a difference in the concave and convex between the laser code and other positions on the cigarette box, it proves that it is a marking method after the real laser code is sprayed, and the conveyor belt continues to work and conveys the cigarette box into the light shield for the next step of identification; If it is detected that there is no difference in convexity between the laser-sprayed code and other positions on the cigarette box, it proves that the code is not laser-sprayed and its authenticity needs further verification. Then the conveyor belt continues to work and transports the cigarette box into the light shield for the next step of identification.

[0016] Optionally, the light intensity adjustment component includes a first retractable roller, a second retractable roller, a spectral band, a color recognition sensor, a light sensor and a power part, the first retractable roller and the second retractable roller are installed at intervals on two inner top walls of the light shield near the end, the spectral band is located below each of the point light sources, and is used to filter the light emitted by each of the point light sources, and the spectral band is respectively wound on the first retractable roller and the second retractable roller; The color recognition sensor is installed at one end of the light shield close to the touch recognition mechanism, and is used to recognize the color depth of the surface of the cigarette box entering the light shield. The light sensor is installed between the color recognition sensor and the image recognition component, and is used to detect the light intensity reflected by the surface of the cigarette box moving directly below the light sensor. The power component can drive the first retracting roller or the second retracting roller to rotate. When the light sensor detects that the light intensity reflected from the surface of the cigarette box is too strong or too weak, the power component drives the spectral band to adjust to an appropriate light intensity through the first retracting roller or the second retracting roller.

[0017] By adopting the above technical solution, when a cigarette box enters the light shield and needs to be further identified, the color recognition sensor identifies the color depth of the cigarette box surface, and then controls the power member to retract the first or second retracting roller to adjust the spectrum band under the point light source. At the same time, the light sensor detects the intensity of light reflected on the cigarette box, thereby controlling the adjustment amount of the spectrum band, so that the final light intensity irradiated on the cigarette box is within a suitable range. Then, the image recognition component is used to more accurately identify the laser code on the surface of the cigarette box, greatly reducing the interference of the external environment and making the detection result more accurate.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 , further details of this application are given.

[0031] The embodiment of the present application discloses a cigarette laser coding device with an automatic identification function.

[0032] A cigarette laser coding device with automatic identification function, referring to Figure 1 , comprising a workbench 1, on which a conveyor belt 11 is arranged, and along the length direction of the conveyor belt 11, the workbench 1 is sequentially provided with: The laser coding mechanism 2 is used to perform laser coding on the surface of the cigarette box placed on the conveyor belt 11; The touch recognition mechanism 3 is used to correct the placement position of the cigarette box and to perform contact recognition on the laser code on the surface of the cigarette box; The light shield 12 is used to shield the complex ambient light from the outside world; An image recognition mechanism 5 is provided in the light shield 12, and the image recognition mechanism 5 is used to adjust the light intensity according to the color depth of the surface of the cigarette box entering the light shield 12, and is used to perform image recognition on the laser code on the surface of the cigarette box; The unloading mechanism 6 is used to classify and unload the cigarette boxes identified by the touch recognition mechanism 3 and the image recognition mechanism 5 into qualified and unqualified cigarette boxes; When the touch recognition mechanism 3 recognizes that the laser code on the surface of the cigarette box is fake, the image recognition mechanism 5 does not work, and the unloading mechanism 6 unloads the cigarette box recognized as fake into the unqualified area; When the touch recognition mechanism 3 recognizes that the laser coding on the surface of the cigarette box is true, the image recognition mechanism 5 recognizes the cigarette box and adjusts the light intensity in the light shield 12, and recognizes the laser coding on the surface of the cigarette box. The unloading mechanism 6 unloads the cigarette box to the corresponding area according to the recognition result.

[0033] Reference Figure 1 The touch recognition mechanism 3 includes a position adjustment component for adjusting the placement position and angle of the cigarette box placed on the conveyor belt 11, and a touch component for touch recognition of the laser code on the surface of the cigarette box adjusted by the position adjustment component.

[0034] When it is needed to be applied in scenes such as law enforcement inspections, the cigarette boxes are placed on the conveyor belt 11 in turn, the position adjustment component will adjust the placement angle and position of the placed cigarette boxes, and then the touch component will perform contact recognition on the laser code on the upper surface of the adjusted cigarette box to determine the authenticity of the laser code on the cigarette box, thereby seizing fake cigarettes and punishing those who sell fake cigarettes.

[0035] Reference Figure 1 The position adjustment component includes a screw rod 31, a support rod 32, an elastic telescopic rod 33 and an adjusting wheel 34. The screw rod 31 is installed above the conveyor belt 11, and can drive the screw rod 31 to rotate when the touch component is activated. There are two support rods 32, and the two support rods 32 are respectively sleeved on the screw rod 31, and the thread rotation direction between the screw rod 31 and the two support rods 32 is opposite.

[0036] There are multiple groups of elastic telescopic rods 33 and adjusting wheels 34, and the elastic telescopic rods 33 and adjusting wheels 34 on the two support rods 32 correspond one to one. The elastic telescopic rod 33 is installed at one end of the support rod 32 away from the screw rod 31, and the adjusting wheel 34 is rotatably installed at the end of the elastic telescopic rod 33 away from the support rod 32.

[0037] When the cigarette box moves to the bottom of the touch assembly, the conveyor belt 11 is suspended, the touch assembly drives the screw rod 31 to rotate, the screw rod 31 drives the two support rods 32 to move in a direction close to each other, so that the two support rods 32 drive the two rows of adjustment wheels 34 to move to both sides of the cigarette box, and when the two rows of adjustment wheels 34 contact the side wall of the cigarette box, the elastic telescopic rod 33 will shrink, and when it shrinks to a certain extent, the elastic telescopic rod 33 will react to the side of the cigarette box to correct the position of the cigarette box. When the cigarette box is corrected, the touch assembly will touch and identify the laser code on the upper surface of the cigarette box.

[0038] Reference Figure 1 The touch assembly includes a first telescopic member 35, a connecting rod 36, a mounting plate 37 and a capacitive touch sensor 38. The first telescopic member 35 is installed above the conveyor belt 11. The connecting rod 36 is coaxially fixed with the telescopic end of the first telescopic member 35. The mounting plate 37 is fixed to the end of the connecting rod 36 away from the first telescopic member 35. The capacitive touch sensor 38 is installed on the side of the mounting plate 37 away from the connecting rod 36.

[0039] A rack 9 is fixed on the connecting rod 36 along the length direction, and a gear 8 meshing with the connecting rod 36 is correspondingly arranged on the screw rod 31. When the first telescopic member 35 is extended, the screw rod 31 can drive the adjusting wheels 34 to move in a direction close to each other.

[0040] After the two rows of adjustment wheels 34 adjust the position of the cigarette box, the first telescopic member 35 continues to extend, driving the mounting plate 37 to move toward the upper surface of the cigarette box through the connecting rod 36, so that the capacitive touch sensor 38 finally contacts the upper surface of the cigarette box, thereby performing contact recognition of the laser code on the cigarette box: If it is detected that there is a difference in the concave and convex between the laser code and other positions on the cigarette box, it proves that it is a marking method after the real laser code is sprayed, and the conveyor belt 11 continues to work and conveys the cigarette box to the light shield 12 for the next step of identification; If it is detected that there is no difference in projections and depressions between the laser-sprayed code and other positions on the cigarette box, it is proved that the code is not laser-sprayed and its authenticity needs to be further verified. Then the conveyor belt 11 continues to work and conveys the cigarette box to the light shield 12 for the next step of identification.

[0041] Reference Figure 1 The image recognition mechanism 5 includes a plurality of point light sources 51 arranged on the top of the light shield 12, a light intensity adjustment component 52 for adjusting the light intensity in the light shield 12 according to the color depth of the surface of the cigarette box entering the light shield 12, and an image recognition component 53 for performing image recognition on the laser-sprayed code on the surface of the cigarette box after the light intensity is adjusted.

[0042] When the cigarette box enters the light shield 12 and further inspection is required, the light intensity adjustment component 52 first identifies the color depth of the surface of the cigarette box, and then adjusts the light intensity of the point light source 51 covering the cigarette box. When the light intensity reaches the appropriate range, the image recognition component 53 identifies the laser code on the surface of the cigarette box, thereby detecting the authenticity of the code or detecting the quality of the code.

[0043] Reference Figure 1 The light intensity adjustment component 52 includes a first retractable roller 521, a second retractable roller 522, a spectrum band 523, a color recognition sensor 524, a light sensor 525 and a power member 526. The first retractable roller 521 and the second retractable roller 522 are installed at intervals on two inner top walls near the end of the light shield 12. The spectrum band 523 is located below each point light source 51 and is used to filter the light emitted by each point light source 51. The spectrum band 523 is respectively wound on the first retractable roller 521 and the second retractable roller 522. The color recognition sensor 524 is installed at one end of the light shield 12 close to the touch recognition mechanism 3, and is used to recognize the color depth of the surface of the cigarette box entering the light shield 12. The light sensor 525 is installed between the color recognition sensor 524 and the image recognition component 53, and is used to detect the light intensity reflected by the surface of the cigarette box moving to the bottom of the light sensor 525. The power member 526 can drive the first retracting roller 521 or the second retracting roller 522 to rotate. When the light sensor 525 detects that the light intensity reflected from the surface of the cigarette box is too strong or too weak, the power member 526 drives the spectral band 523 to adjust to the appropriate light intensity through the first retracting roller 521 or the second retracting roller 522.

[0044] When the cigarette box enters the light shield 12 and needs to be further identified, the color recognition sensor 524 identifies the color depth of the cigarette box surface, and then controls the power member 526 to retract the first retracting roller 521 or the second retracting roller 522, so that the spectrum band 523 under the point light source 51 is adjusted, and the light sensor 525 detects the light intensity reflected on the cigarette box, thereby controlling the adjustment amount of the spectrum band 523, so that the light intensity finally irradiated on the cigarette box is within a suitable range. Then, the image recognition component 53 is used to more accurately identify the laser code on the surface of the cigarette box, greatly reducing the interference of the external environment, and making the detection result more accurate.

[0045] Reference Figure 1 The power part 526 includes a driving motor 5261, a pulley 5262 and a belt 5263. The output end of the driving motor 5261 is coaxially fixed with the first retracting roller 521 or the second retracting roller 522. In the present embodiment, the output end of the driving motor 5261 is coaxially fixed with the end of the first retracting roller 521. The first retracting roller 521 and the second retracting roller 522 are coaxially provided with pulleys 5262. The belt 5263 is respectively connected to the pulleys 5262 on the first retracting roller 521 and the second retracting roller 522.

[0046] When the first retracting roller 521 or the second retracting roller 522 needs to be retracted or extended, the driving motor 5261 drives the pulley 5262 to rotate, and drives the first retracting roller 521 and the second retracting roller 522 to rotate synchronously through the belt 5263, thereby moving the spectral band 523 to a suitable position and appropriately adjusting the light intensity of the point light source 51.

[0047] The image recognition component 53 includes an image sensor and a controller arranged at one end of the light shield 12 close to the unloading mechanism 6. The recognition end of the image sensor faces the conveyor belt 11. The image sensor, drive motor 5261, color recognition sensor 524 and light sensor 525 are all electrically connected to the controller.

[0048] Reference Figure 1 Two groups of unloading mechanisms 6 are respectively arranged on both sides of the conveyor belt 11. Each group of unloading mechanisms 6 includes a second telescopic member 61 and a push plate 62. The second telescopic member 61 is installed on one side of the conveyor belt 11, and the telescopic end is fixedly connected to the push plate 62.

[0049] When the laser code on the cigarette box is recognized as true and clear, the second telescopic member 61 pushes the corresponding push plate 62 to push the cigarette box to the qualified area. When the laser code on the cigarette box is recognized as false and unclear, the other second telescopic member 61 pushes the corresponding push plate 62 to push the cigarette box to the unqualified area. Both the qualified area and the unqualified area are equipped with a feed frame 7, and the two feed frames 7 classify and collect qualified or unqualified cigarette boxes respectively.

[0050] The implementation principle of a cigarette laser coding device with automatic identification function in an embodiment of the present application is as follows: the laser coding mechanism 2 is capable of laser coding the surface of a cigarette box. When it is necessary to inspect the surface of the cigarette box after laser coding or to inspect other cigarette boxes, the other cigarette boxes here are suitable for law enforcement inspections or inspections in complex environments: when the touch recognition mechanism 3 recognizes that the laser coding on the surface of the cigarette box is false, the image recognition mechanism 5 does not work, and the unloading mechanism 6 unloads the cigarette box to the unqualified area; when the touch recognition mechanism 3 recognizes that the laser coding on the surface of the cigarette box is true, the image recognition mechanism 5 recognizes the cigarette box and adjusts the light intensity in the light shield 12, and recognizes the laser coding on the surface of the cigarette box, and the unloading mechanism 6 unloads the cigarette box to the corresponding area according to the recognition result.
