Description

Technical Field

[0001] The present invention relates to the technical field of material surface detection, and particularly to an all-dimensional on-line detection device for the appearance of cigarette cases based on image recognition. Background Art

[0002] In the field of tobacco packaging production, the appearance quality of cigarette cases is an important indicator of the product's market competitiveness, directly affecting consumers' perception and trust in the brand. Currently, the main methods for detecting the appearance of cigarette cases are manual sampling inspection and traditional machine vision detection. For manual sampling inspection, inspectors need to visually check and use simple tools to check the printing defects, box body damage, gold stamping deviation, etc. on the surface of cigarette cases one by one. There are problems such as low detection efficiency (the detection speed of a single manual position is about 30 - 50 per minute), high labor intensity, and high missed detection rate due to visual fatigue easily caused by long-term operation; moreover, the subjectivity of manual detection is strong, and different inspectors have different judgment criteria for defects, making it difficult to ensure the consistency of detection results.

[0003] Traditional machine vision detection devices mostly use single-group cameras or fixed-angle shooting methods, and single cigarette cases are conveyed one by one through a conveyor belt for single-sided detection. Although the detection efficiency is improved to a certain extent, they cannot cover all areas of the top, bottom, and sides of the cigarette case. For example, some devices can only detect the printing quality of the front and side of the cigarette case, and it is difficult to identify the defects of the gold stamping pattern on the top surface, the pasted label on the bottom surface, and the corners of the box body; some devices using multi-angle detection need to use a complex mechanical flipping mechanism to turn over the cigarette case, which has problems such as complex structure, high failure rate, and easy scratching of the cigarette case surface during the flipping process. Moreover, only one cigarette case can be detected at a time, and the detection speed is slow, unable to meet the high-speed detection requirements of modern tobacco packaging production lines. Summary of the Invention

[0004] In order to overcome the above-mentioned drawbacks, the present invention provides an all-dimensional on-line detection device for the appearance of cigarette cases based on image recognition.

[0005] The technical solution is as follows: An all-dimensional online detection device for the appearance of cigarette cases based on image recognition, which includes a bracket, a controller, a support disk, a motor, a turntable, an all-dimensional detection component, an alarm, a guide ring, a support member, a clamping rod, a ball, a rotating component, and a conveying component. The controller is installed on the front side of the bracket. The front and rear sides of the middle part of the bracket are respectively connected with support disks. A motor is installed in the middle of the front support disk. The inner sides of the support disks are all rotatably connected with turntables. The output shaft of the motor penetrates through the front support disk and is connected to the front turntable. An all-dimensional detection component is installed between the two turntables. Multiple groups of array cameras are installed on the all-dimensional detection component at circumferential intervals. Alarms are connected to the all-dimensional detection component near each group of array cameras. The alarms, the all-dimensional detection component, and the motor are all electrically connected to the controller. The outer sides of the support disks are connected with guide rings. Multiple support members are connected to the turntables at circumferential intervals. The outer sides of the support members are slidably connected with clamping rods. The outer ends of the clamping rods are hinged with balls that rollingly contact the guide rings. A rotating component is provided on the support members, and a conveying component is provided on the bracket.

[0006] As a further preferred solution, an image processing unit is integrated in the all-dimensional detection component.

[0007] As a further preferred solution, the inner ends of the clamping rods are provided with rubber materials.

[0008] As a further preferred solution, the rotating component includes gears, clamping springs, short tooth groups, and long tooth groups. Gears are rotatably connected to the outer sides of the support members. The gears are spline-connected to the corresponding clamping rods. Clamping springs are connected between the clamping rods and the corresponding gears. Transmission tooth groups are provided in some areas on the outer side walls of the support disks, including three short tooth groups evenly distributed at intervals on the left side and a long tooth group continuously arranged on the right side.

[0009] As a further preferred solution, the gears have 20 teeth in total, the short tooth groups have five teeth, and the transmission ratio is 4:1.

[0010] As a further preferred solution, the conveying component includes a transfer component, a feeding component, a discharging component, a transmission, a side position detection component, a limit ring, and a conveyor belt. The transfer component and the feeding component are installed on the left side of the top of the bracket. The feeding component is located on the right side of the transfer component. The discharging component is installed on the right side of the top of the bracket. Two transmissions are installed between the power shafts of the transfer component and the feeding component, which can adjust the conveying speeds of the transfer component and the feeding component. Side position detection components are symmetrically installed on the feeding component. And alarms are also installed on the side position detection components. The side position detection components and the alarms are all electrically connected to the controller. The side position detection components are also electrically connected to the image processing unit in the all-dimensional detection component. A limit ring is connected to the outer side of the turntable. A conveyor belt is wound between the front and rear ends of one of the power shafts of the feeding component and the discharging component and the corresponding limit rings.

[0011] As a further preferred scheme, it also includes a stabilizing rod, a support rod and a tension spring. The stabilizing rod is slidably connected to the support member, the support member is connected to a position in the same straight line as the stabilizing rod, and a tension spring is connected between the support rod and the corresponding stabilizing rod. The inner end of the gear is designed as a square constraint structure, and the stabilizing rod is adapted to the square constraint structure to form a contact fit.

[0012] As a further preferred scheme, it also includes a fixed rod and a limit frame. The top of the bracket is located at the front and rear sides of the transfer assembly, the feeding assembly and the discharging assembly, and a plurality of fixed rods are connected at intervals. The limit frame is installed between the upper ends of the fixed rods on the same side by bolts. The limit frame is located above the transfer assembly, the feeding assembly and the discharging assembly, and is used to limit the vertical displacement of the carton during transportation.

[0013] The present invention has the following advantages: 1. Through multiple groups of circumferentially distributed array cameras and a secondary all-round rotation detection mechanism for cigarette boxes, 360° no-dead-angle detection of the top, bottom and four sides of the cigarette box can be achieved. Combined with the analog signal digital processing and defect recognition algorithm of the image processing unit, the detection blind spots can be effectively eliminated, greatly improving the control accuracy of the appearance quality of the cigarette box.

[0014] 2. The clamping structure of the guide ring and the ball, as well as the precise flipping mechanism composed of the gear-short tooth group and the long tooth group, cooperate with the positioning and stabilizing components of the stabilizing rod and the tension spring to ensure that the cigarette box maintains a precise angle during the clamping, flipping and rotation process, and ensure the accuracy and stability of the image acquisition position.

[0015] 3. The design of the stabilizing rod and the square structure inside the gear. When the gear rotates, the square structure pushes the stabilizing rod, and the elastic force of the tension spring makes the stabilizing rod press against the square structure, thereby providing additional support for the rotation of the gear and reducing shaking and deviation during rotation.

[0016] 4. After the gear rotates 90 degrees each time, the abutment between the stabilizing rod and the square structure can ensure that the gear stops accurately at the predetermined position, ensuring the accuracy and consistency of the cigarette box angle adjustment and improving the accuracy and reliability of cigarette box detection.

Detailed implementation mode

[0031] Embodiment 1: An all-dimensional on-line detection device for the appearance of cigarette cases based on image recognition, as Figures 1 - 8As shown in the figure, it includes a bracket 1, a controller 101, a support disk 102, a motor 103, a turntable 104, a full-dimensional detection component 105, an alarm 106, a guide ring 201, a support member 202, a clamping rod 203, a ball 204, a rotating component and a conveying component. The bracket 1 serves as the main support structure of the device. The controller 101 is installed on the front side of the bracket 1 through bolts and integrates a PLC control module and a data processing unit, which are used to coordinate the actions of each actuator and receive and process detection signals. On the front and back sides of the middle part of the bracket 1, there are support disks 102 arranged oppositely. In the middle of the front support disk 102, a motor 103 is installed through bolts as the power source. The inner sides of the support disks 102 are rotatably connected to the turntables 104. The output shaft of the motor 103 penetrates the front support disk 102 and is connected to the front turntable 104 through a coupling, thereby driving the turntable 104 to rotate. A full-dimensional detection component 105 is installed between the two turntables 104. Along the circumference of the full-dimensional detection component 105, multiple groups of array cameras are installed at intervals. The multiple groups of array cameras are distributed circumferentially, which can realize the synchronous detection operation of multiple cigarette cases. By taking pictures of multiple sides of the cigarette case, image information of multiple sides of the cigarette case can be obtained to achieve full-dimensional detection and reduce the detection blind area. An alarm 106 is connected to the position of each group of array cameras on the full-dimensional detection component 105. When the image processing unit determines that there are appearance defects (such as gold stamping deviation, box surface wrinkles, etc.) on the cigarette case, the controller 101 triggers the corresponding alarm 106, and uses a flashing light and a beeping signal to prompt manual review. The alarm 106, the full-dimensional detection component 105 and the motor 103 are all electrically connected to the controller 101. Guide rings 201 are connected to the outer sides of the support disks 102. Multiple support members 202 are connected to the turntable 104 at intervals along the circumference, and the number of them matches the number of array camera groups. The outer sides of the support members 202 are slidably connected to the clamping rods 203. The outer ends of the clamping rods 203 are hinged with balls 204. The balls 204 are in rolling contact with the guide ring 201, and a 45° inclined guide surface is provided at the left end of the guide ring 201. When the turntable 104 rotates along the circumference, the balls 204 slide along the inclined surface of the guide ring 201, pushing the clamping rods 203 to translate inward, and the cigarette case is radially clamped through the clamping rods 203. The inner ends of the clamping rods 203 are made of rubber material. When clamping the cigarette case, it can prevent the metal clamping rods 203 from directly contacting the surface of the cigarette case and causing scratches, indentations and other damages. And the surface of the rubber material has a certain roughness, which can generate a large frictional force when contacting the surface of the cigarette case. During the process of the cigarette case rotating and flipping at high speed with the turntable 104, it can ensure that the cigarette case will not slide or shift. A rotating component is provided on the support member 202, and a conveying component is provided on the bracket 1.

[0032] The full-dimension detection component 105 integrates an image processing unit (DSP chipset) inside, with built-in image noise reduction, edge detection, and defect recognition algorithms. It can convert the analog signal output by the camera into a digital image in real time, and transmit the detection data (qualified / defect type) to the controller 101 after feature extraction.

[0033] As Figures 5 - 7 shown, the rotating component includes a gear 205, a clamping spring 206, a short tooth group 207, and a long tooth group 208. Gears 205 are rotatably connected to the outside of the support member 202. The gears 205 are spline-connected to the corresponding clamping rods 203. Clamping springs 206 are connected between the clamping rods 203 and the corresponding gears 205. A transmission tooth group is provided in a partial area on the outer side wall of the support disk 102, including three short tooth groups 207 evenly distributed at intervals on the left side and a long tooth group 208 arranged continuously on the right side. The gear 205 has 20 teeth, the short tooth group 207 has five teeth, and the transmission ratio is 4:1, realizing a precise 90° flip of the cigarette case. When the gear 205 meshes with the long tooth group 208, a continuous 360° rotation of the cigarette case is realized, meeting the full-dimension image acquisition requirements.

[0034] As Figure 1 、 Figure 2 and Figure 8 shown, the conveying component includes a transfer component 301, a feeding component 302, a discharging component 303, a transmission 304, a side position detection component 305, a limit ring 306, and a conveyor belt 307. The transfer component 301 and the feeding component 302 are installed on the left side of the top of the bracket 1 through bolts. The feeding component 302 is located on the right side of the transfer component 301. The discharging component 303 is installed on the right side of the top of the bracket 1. Two symmetrically arranged transmissions 304 are installed between the power shafts of the transfer component 301 and the feeding component 302, which can adjust the conveying speeds of the transfer component 301 and the feeding component 302. The cigarette cases are input into the transfer component 301 in a dense arrangement. The speed of the feeding component 302 is 1 / 3 of that of the transfer component 301. The speed difference is used to change the dense arrangement of the cigarette cases into an equidistant arrangement, ensuring the precise alignment detection of individual cigarette cases. Side position detection components 305 (linear array cameras + bar-shaped light sources) are symmetrically installed on the front and back of the feeding component 302. Moreover, an alarm is also installed on the side position detection component (305). The side position detection component 305 and the alarm are both electrically connected to the controller 101. The side position detection component 305 is also electrically connected to the image processing unit in the full-dimension detection component 105. The side position detection component 305 is used to detect the flatness and printing defects of the front and back walls of the cigarette case, and the detection data is synchronously connected to the image processing unit. A limit ring 306 is connected to the outside of the turntable 104. A conveyor belt 307 is wound between the front and rear ends of one of the power shafts of the feeding component 302 and the discharging component 303 and the corresponding limit ring 306, so as to transmit the power of the turntable 104 to the feeding component 302 and the discharging component 303 through the conveyor belt 307.

[0035] The cigarette cases are fed into the transfer assembly 301 in a closely arranged manner. The operator starts the motor 103 by operating the controller 101. The output shaft of the motor 103 rotates to drive the front turntable 104 and the full-dimensional detection assembly 105 to rotate. The rear turntable 104 rotates accordingly. The turntable 104 drives the limit ring 306 to rotate. The limit ring 306 transmits power to the power shafts of the feeding assembly 302 and the discharging assembly 303 through the conveyor belt 307, causing the belts of the feeding assembly 302 and the discharging assembly 303 to start running. At the same time, under the action of the transmission 304, part of the power of the feeding assembly 302 is transmitted to the transfer assembly 301. The transmission 304 precisely adjusts the power so that the rotation speed of the transfer assembly 301 reaches three times that of the feeding assembly 302. When the transfer assembly 301 conveys the cigarette cases to the right to the feeding assembly 302, due to the speed difference between the two, the cigarette cases will automatically form an equidistant interval arrangement on the feeding assembly 302 and continue to be conveyed at a uniform speed, preparing for the subsequent detection process.

[0036] When the cigarette case moves with the feeding assembly 302 to a position aligned with the side detection assembly 305, the controller 101 controls the motor 103 to pause, and the conveyance of the cigarette case also pauses accordingly. At this time, the side detection assembly 305 automatically starts to perform an appearance inspection on the front and rear side walls of the cigarette case. The side detection assembly 305 transmits the collected image data to the image processing unit in the full-dimensional detection assembly 105. After receiving the data, the image processing unit quickly converts the analog image signal into a digital signal and uses a preset image analysis algorithm to process and analyze the image. If the detection result shows that the cigarette case is qualified, the image processing unit will send a qualified signal to the controller 101. After receiving the signal, the controller 101 restarts the motor 103, and the cigarette case continues to be conveyed on the feeding assembly 302; if it is detected that the cigarette case has an appearance defect, the alarm 106 on the side detection assembly 305 will immediately emit an alarm sound and turn on the warning light to remind the operator to promptly remove the unqualified cigarette case to prevent it from entering the subsequent detection process.

[0037] After the motor 103 restarts, the turntable 104 continues to rotate circumferentially, driving the support member 202, the clamping rod 203, and the ball 204 mounted on the turntable 104 to rotate synchronously. When the ball 204 on the clamping rod 203 moves to contact the inclined surface structure of the guide ring 201, due to the action of the inclined surface of the guide ring 201, the ball 204 will roll along the inclined surface, thereby pushing the clamping rod 203 to move inward. At this time, the clamping spring 206 between the clamping rod 203 and the support member 202 is compressed. During the inward movement of the clamping rod 203, exactly one cigarette case is conveyed to a position aligned with the clamping rod 203, and the clamping rod 203 will accurately clamp and fix the cigarette case. After the array camera aligned with the cigarette case on the full-dimensional detection component 105 recognizes the cigarette case through the built-in image recognition algorithm, it will send a signal to the controller 101. The controller 101 immediately controls the motor 103 to stop running, and the array camera quickly takes a picture of one side of the cigarette case to obtain the image information of this side. After the shooting is completed, the image information is immediately transmitted to the image processing unit, and the image processing unit quickly analyzes and processes the image. Within a preset specific detection time, if the image processing unit determines that the cigarette case is unqualified, the controller 101 will control the corresponding alarm 106 to sound an alarm, reminding the operator to record the relevant information of the unqualified cigarette case for subsequent processing; if the detection is qualified, the controller 101 will restart the motor 103 to make the turntable 104 continue to rotate. The rotation of the turntable 104 drives the clamping rod 203 and the gear 205 splined thereto to rotate circumferentially. When the gear 205 moves to mesh with the short tooth group 207 on the left part of the outer wall of the support disk 102, the short tooth group 207 will generate a driving force on the gear 205 to drive the gear 205 to rotate. Due to the spline connection between the gear 205 and the clamping rod 203, the rotation of the gear 205 will cause the clamping rod 203 and the clamped cigarette case to rotate synchronously by 90 degrees, realizing the turning operation of the cigarette case. After the cigarette case is turned over, the motor 103 pauses again, and the full-dimensional detection component 105 detects the other side of the turned-over cigarette case. The detection process is the same as that of the single-side detection. Through the sequential action of the three short tooth groups 207, the cigarette case will rotate three times by 90 degrees respectively, thereby realizing the detection of the other three sides.

[0038] After the four sides of the cigarette box are tested, the turntable 104 continues to rotate intermittently in the circumferential direction. When the gear 205 moves to mesh with the long tooth group 208 on the right part of the outer wall of the support plate 102, the long tooth group 208 will continue to drive the gear 205 to rotate. Due to the layout range design of the long tooth group 208, the cigarette box will be continuously rotated 90 degrees in this process, thereby realizing the image acquisition and shooting of all aspects of the cigarette box to complete the secondary inspection. The secondary inspection can further improve the accuracy of the inspection and ensure that the possible minor defects of the cigarette box can be detected. After the secondary inspection is completed, the clamping rod 203 that clamps the cigarette box moves to a position that is separated from the guide ring 201 as the turntable 104 rotates. At this time, due to the resetting effect of the clamping spring 206, the clamping rod 203 will move outward and reset, thereby loosening the clamping of the cigarette box, and the cigarette box will fall onto the discharge assembly 303, and will be conveyed to the right by the discharge assembly 303 to the next process, or for subsequent collection operations. For cigarette boxes that are detected to have quality problems during the entire inspection process, the operator can take them out of the conveyor line when they reach the discharge assembly 303, and process them separately. Through the above series of operating procedures, the present device can realize all-round and continuous online inspection of the appearance of cigarette boxes, effectively improving the efficiency and accuracy of cigarette box appearance inspection.

[0039] Embodiment 2: Based on embodiment 1, Figures 9 - 11 As shown, it also includes a stabilizing rod 401, a support rod 402 and a tension spring 403. The stabilizing rod 401 is slidably connected to the support member 202. The support rod 402 is welded on the support member 202 at a position in the same straight line as the stabilizing rod 401. The tension spring 403 is connected between the support rod 402 and the corresponding stabilizing rod 401. The inner end of the gear 205 is designed as a square constraint structure, and the stabilizing rod 401 is adapted to the square constraint structure to form a contact fit.

[0040] When the gear 205 completes a 90° indexing rotation under the driving force of the short tooth group 207, the side of the square structure pushes the stabilizing rod 401 axially, causing the tension spring 403 to produce elastic deformation and store potential energy; when the gear 205 rotates to the predetermined position, the restoring force of the tension spring 403 drives the stabilizing rod 401 to press against the positioning plane of the square structure, forming a rigid limit constraint, effectively eliminating the transmission gap of the gear 205, ensuring high-precision control of the flipping angle of the cigarette box, and achieving a stable operating effect of "dynamic free rotation and static rigid positioning".

[0041] like Figures 12 - 13As shown in the figure, it further includes a fixed rod 501 and a limit frame 502. A plurality of fixed rods 501 are connected at intervals at the front and rear sides of the transfer assembly 301, the feeding assembly 302 and the discharging assembly 303 on the top of the bracket 1. A limit frame 502 is installed between the upper ends of the fixed rods 501 on the same side by bolts. The limit frame 502 is located above the transfer assembly 301, the feeding assembly 302 and the discharging assembly 303, and is used to limit the vertical displacement during the conveying process of the paper box. The limit frame 502 adopts a height-adjustable design. The operator can adjust the height positioning of the limit frame 502 on the fixed rod 501 by adjusting the bolt-nut combination according to the actual height of the paper box. A silica gel anti-slip and buffer strip is pasted on the bottom surface of the limit frame 502, and there is a floating gap of 5 mm - 10 mm between it and the top surface of the cigarette case. While effectively restricting the vertical movement of the cigarette case, it avoids causing indentation damage to the box surface. When the paper box is conveyed by each conveying assembly, the limit frame 502 ensures the spatial stability during the conveying process of the paper box through the top surface constraint, and effectively prevents abnormal conditions such as dumping and offset from occurring.
