Description

Technical Field

[0001] This invention relates to the field of inspection and packing technology, and in particular to an integrated inspection and packing machine based on AI vision. Background Technology

[0002] Currently, in the visual recognition and packaging industry, product inspection and packing often adopt a "separate equipment + manual connection" operation mode: first, visual inspection equipment judges the appearance, size, or integrity of the product, and then the qualified products are transferred to the packing equipment manually, or the material transfer between equipment is achieved through a conveyor belt. This mode has obvious limitations. On the one hand, the inspection and packing equipment operate independently, requiring additional connection mechanisms or manual intervention, which can easily lead to missed inspections and incorrect packing due to material transfer deviations. On the other hand, the two sets of equipment occupy production space separately and require separate parameter debugging, which not only increases the cost of equipment procurement and maintenance, but also makes it difficult to adapt to the rapid changeover production needs of small batches and multiple product categories.

[0003] Chinese Patent CN117922933B discloses an automatic paper stick detection and packing machine. The machine separates paper sticks one by one by rotating a roller-shaped detection table counterclockwise. A vision inspection mechanism photographs the paper sticks at the top of an arched section in both front and back directions. When the vision inspection mechanism detects a defective paper stick at the top of the arched section, it sends a defective signal to the detection and processing terminal. A defective paper stick capture recorder records the time of detection. The detection and processing terminal then controls an air-blowing rejection mechanism to blow the defective paper stick upwards from the paper stick placement slot and remove it after a certain period. After removing the defective paper sticks, a directional ring conveyor mechanism transports qualified paper sticks oriented and into cartons on a vibrating receiving and packing mechanism. When a qualified paper stick at the front end of the directional ring conveyor passes a front-end counter, the counter records the number of qualified paper sticks and sends the data back to the detection and processing terminal, enabling the qualified paper sticks to be quantitatively packed into cartons.

[0004] However, since the above-mentioned device is not compatible with the detection and packing of bottle-shaped workpieces, it is difficult to achieve rotational visual inspection of bottle-shaped workpieces while ensuring efficiency. At the same time, visual acquisition needs to be performed one by one during the inspection process, resulting in low inspection efficiency. Therefore, the technical solution of this invention is proposed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the prior art, the present invention is proposed.

[0012] As a preferred embodiment of the AI ​​vision-based inspection and packing integrated machine of the present invention, the visual inspection unit is controlled in sync with the conveyor belt, and the moving speed of the conveyor belt is adjusted in real time to match the visual image acquisition speed. There are 10 image acquisition units, which are located around the conveyor belt.

[0013] As a preferred embodiment of the AI ​​vision-based inspection and packing integrated machine of the present invention, the conveyor belt adopts a modular design, and the rotation speed of each conveyor belt is controlled independently. In the visual inspection stage, three parallel conveyor belts are used, and the workpieces to be inspected are arranged and placed by a robotic arm. The image acquisition device simultaneously acquires the image information of the three workpieces to be inspected for identification and evaluation.

[0014] As a preferred embodiment of the AI ​​vision-based inspection and packing integrated machine of the present invention, wherein: the conveyor belt is a disc-shaped conveyor belt, and the detection logic is as follows:

[0015] The disc rotates clockwise. After being initially placed on the disc-shaped conveyor belt, it rotates half a circle to collect images and perform initial inspection. Qualified products are then sorted by a robotic arm and sent to the packaging process.

[0016] For products that fail the initial inspection, the robotic arm does not sort them. After a half-circle rotation, it performs a second image acquisition and evaluates the results again. If both evaluations are unqualified, the product is designated as unqualified and sorted by the robotic arm to the unqualified area.

[0017] As a preferred embodiment of the AI ​​vision-based inspection and packing integrated machine of the present invention, the conveyor belt includes a belt layer sleeved on the surface, a support plate is provided inside the belt layer, the support plate is used to support the belt layer and the workpiece to be inspected, a floating disk is provided on the belt layer, and when the conveyor belt slides against the support plate, the floating disk rotates relative to the conveyor belt, and at the same time drives the workpiece to be inspected to rotate.

[0018] As a preferred embodiment of the AI ​​vision-based inspection and packing integrated machine of the present invention, wherein: a rotating groove is provided on the belt layer, a T-shaped ring is provided on the rotating groove, a first sealing groove is provided on the floating disk, and the floating disk is rotatably disposed on the inner wall of the rotating groove.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] Reference Figures 1-9 This is the first embodiment of the present invention. This embodiment provides an AI vision-based inspection and packing integrated machine for the automated inspection, sorting and packing of bottle and can workpieces, realizing integrated inspection and packaging operations, significantly reducing labor costs and improving inspection accuracy and production efficiency.

[0043] Specifically, it includes a housing 100, a conveyor belt 101 that runs through the housing 100, and a workpiece 102 to be inspected that is placed on the conveyor belt 101;

[0044] The visual inspection unit includes image acquisition units 200 located on both sides of the conveyor belt 101. The image acquisition units 200 are height-adjusted according to the size of the workpiece 102 to be inspected. The image acquisition units 200 are used to collect image information of the workpiece 102 to be inspected and transmit it to the server. The server calls the AI ​​visual recognition algorithm to perform data recognition and quality classification on the image information.

[0045] It also includes a sorting unit 201, which sorts the workpieces 102 to be inspected according to the quality classification results of the server;

[0046] And packaging unit 300, which is used to sort and package the quality-classified workpieces 102 to be inspected.

[0047] In this embodiment, the workpiece 102 to be inspected is a bottle or can. In the normal inspection process, it is necessary to manually inspect the size information, color information, and whether there are any defects on the outer wall of the bottle or can.

[0048] Preferably, the housing 100 has at least three compartments inside, and in this embodiment, it is a three-layer design with the conveyor belt 101 located on the top layer, which transports the workpiece 102 to be inspected to the top. The layers are moved between each other by an inclined transition conveyor belt. For the workpiece 102 to be inspected that is relatively heavy in other embodiments, a robotic arm can be used for transfer.

[0049] Specifically, in this embodiment, the housing 100 is integrally molded from corrosion-resistant metal material, providing dustproof and noise-proof functions. It has three independent compartments inside: upper layer: detection layer, middle layer: packaging layer, and lower layer: finished product storage layer. Each compartment is separated by a sealing plate to prevent dust from interfering with the detection accuracy. The outer side of the housing 100 is equipped with a touch operation panel, which communicates with the server and can realize parameter input, status monitoring, data export, and fault alarm functions. The operation panel has a built-in emergency stop button to ensure the safe operation of the equipment.

[0050] Preferably, the upper inspection layer is provided with a main conveyor belt, and the surface of the main conveyor belt is provided with annular anti-slip protrusions to prevent the bottles and cans to be inspected from sliding and shifting during the conveying process; adjustable guide plates are provided on both sides of the main conveyor belt, which are driven by a screw and slider mechanism to adapt to bottles and cans of different diameters.

[0051] Specifically, each partition is equipped with an inclined transition conveyor belt, with the inclination angle set within a reasonable range to avoid workpiece collisions. The surface of the transition conveyor belt is covered with a cushioning material to prevent damage to bottles and cans during interlayer transfer. The feed end of the transition conveyor belt is aligned with the discharge end of the main conveyor belt of the upper layer, and the discharge end is connected to the corresponding mechanism of the lower layer. An arc-shaped guide plate is provided at the connection to guide the workpiece to transition smoothly.

[0052] For heavy bottle and can workpieces with large weight, the interlayer transfer is replaced by an electric robotic arm. The robotic arm is located on the inner side wall of the housing 100 and is equipped with a vacuum suction cup clamp at the end. The suction force of the suction cup is adjustable, and the clamp has a built-in pressure sensor to provide real-time feedback on the adsorption status, preventing the workpiece from falling off and ensuring a stable and reliable transfer process.

[0053] Even better, the vision detection unit is controlled in sync with the conveyor belt 101. The moving speed of the conveyor belt 101 is adjusted in real time to match the speed of vision image acquisition. There are four image acquisition units 200, which are located around the conveyor belt 101.

[0054] More preferably, in other embodiments, the conveyor belt 101 can be modularly designed, with the rotation speed of each conveyor belt 101 controlled individually. In the visual inspection stage, three parallel conveyor belts 101 are used, and the workpieces 102 to be inspected are arranged and placed by a robotic arm. The image acquisition device 200 simultaneously acquires image information of the three workpieces 102 to be inspected for identification and evaluation.

[0055] In summary, the image acquisition module uses high-definition industrial cameras, which are fixed around the main conveyor belt and equipped with electric lifting rods driven by stepper motors. In conjunction with laser rangefinders, the camera height can be automatically adjusted according to the height and dimensions of the workpiece 102 to ensure that the captured image completely covers the entire surface of the workpiece.

[0056] The area around the acquisition zone is equipped with ring-shaped LED fill lights with adjustable brightness to avoid ambient light interference and ensure the authenticity of image colors. The fill lights are triggered synchronously with the camera, turning on when shooting and turning off when not shooting, thus saving energy.

[0057] Even better, the image information captured by the industrial camera is transmitted to the edge server via Ethernet. The server has a built-in AI visual recognition algorithm, which is based on a convolutional neural network training model and is specifically optimized for the inspection items of bottle and can workpieces. The specific inspection contents include: size inspection covering bottle mouth diameter, bottle height, bottle wall thickness; color inspection using a standard color space to compare the uniformity of the main body color and label color; and defect detection to identify scratches, dents, cracks, impurities inside the bottle, label misalignment and damage, etc.

[0058] The server and the servo motor of the main conveyor belt are controlled in sync. The encoder collects the running speed of the conveyor belt 101 in real time and dynamically adjusts the motor speed according to the camera frame rate to ensure that the dwell time of each workpiece 102 in the acquisition area meets the requirements of image acquisition integrity. When the density of workpieces is too high, the server automatically reduces the speed of the conveyor belt 101 to avoid missed detection.

[0059] Among them, the conveyor belt 101 used for simply transporting the workpiece 102 to be inspected has a higher speed than the conveying speed of the vision inspection unit, so that the overall vision inspection efficiency of the device is higher than the efficiency of performing vision inspection one by one.

[0060] More preferably, the three parallel conveyor belts 101 can be replaced with disc-shaped conveyor belts. The discs rotate clockwise. After the workpiece 102 is initially placed on the disc-shaped conveyor belt, it rotates half a turn to collect images and perform initial inspection. Qualified products are sorted by a robotic arm and sent to the packaging process.

[0061] For products that fail the initial inspection, the robotic arm does not sort them. After a half-circle rotation, it performs a second image acquisition and evaluates the results again. If both evaluations are unqualified, the product is designated as unqualified and sorted by the robotic arm to the unqualified area.

[0062] The above settings not only improve the efficiency of visual inspection but also enhance its accuracy, avoiding false positives and missed negatives.

[0063] In this embodiment, the sorting unit 201 includes three channels, corresponding to three quality classification levels. Qualified products directly enter the next compartment of the housing 100 for packaging, while unqualified products enter the rework channel and the scrap channel respectively.

[0064] Specifically, the sorting unit 201 is located at the discharge end of the main conveyor belt and is connected to the server via a signal. It performs sorting actions based on the quality classification results and includes three independent sorting channels, corresponding to the "qualified product channel," "rework channel," and "scrap channel," respectively. Each channel entrance is equipped with a pneumatic fork controlled by a solenoid valve. Each channel entrance is also equipped with a photoelectric sensor to detect the arrival signal of the workpiece in real time and trigger the fork action. The working logic is as follows:

[0065] When the server determines that the size, color, and defects all meet the requirements, the shift fork switches to the qualified product channel, and the workpiece enters the middle packaging area via the transition conveyor belt.

[0066] When the server determines that a single minor defect is present, the toggle switch is switched to the rework channel. The channel is equipped with an RFID tag writer that automatically writes information such as defect type, inspection time, and workpiece number. The workpiece is temporarily stored in the rework storage area. When the storage area is full, a prompt is issued through the operation panel.

[0067] When the server determines that a material has a serious defect or fails the second test, the toggle switch is moved to the scrap channel. The end of the channel is connected to a scrap collection box, which has a built-in weight sensor that triggers an alarm when the box is full.

[0068] Preferably, the packaging unit 300 is located in the middle packaging area of ​​the housing 100 for automated sorting, packing, and sealing of qualified products. It includes a bottle sorting mechanism connected to the discharge end of the qualified product channel, comprising a vibrating bottle sorting tray and a linear conveyor track. The vibrating bottle sorting tray uses vibration to organize disordered workpieces into an upright state. Guide strips are provided on both sides of the linear conveyor track, with the spacing adapted to the diameter of the workpieces to ensure that the workpieces are transported in an orderly single row. A counting sensor is provided at the end of the linear conveyor track to count the number of workpieces entering the packing mechanism in real time.

[0069] It also includes a packing mechanism, which includes a Cartesian coordinate robotic arm and a positioning platform; the end of the Cartesian coordinate robotic arm is equipped with a multi-suction cup gripper, which can adjust the number of grips per time and the gripping spacing matches the preset array. The packing mechanism has a labeling module inside, which is used to print QR code labels containing information such as workpiece batch, inspection pass rate, and production date, and automatically affix them to the side of the carton.

[0070] After being packed, the finished products are transported to the lower storage area of ​​the housing 100 via the lower conveyor belt. The storage area is equipped with partitions, which can store products according to batches. The end of the lower conveyor belt is equipped with a finished product counting sensor, and the cumulative output is displayed in real time on the operation panel.

[0071] In summary, during operation, operators preset workpiece specifications, inspection standards, and packing parameters via the touch panel, then place the bottles and cans to be inspected in batches onto the upper main conveyor belt. The workpieces are smoothly transported to the visual inspection area under the guidance of the guide plate. The laser rangefinder sensor adjusts the camera height, and the supplementary lighting is turned on simultaneously. The surrounding industrial cameras collect images of the entire surface of the workpiece and transmit them to the edge server. The AI ​​algorithm then completes the quality judgment based on dimensions such as size, color, and defects. According to the judgment results, the sorting unit 201 uses pneumatic forks to divert qualified products, rework products with single minor defects, and scrap products with serious defects to the corresponding channels. Qualified products enter the middle packaging area via the transition conveyor belt, where they undergo bottle sorting, precise packing by the robotic arm, tape sealing, and QR code labeling. Finally, the finished products are transported to the lower storage area for batch storage. The equipment provides real-time feedback on the operating status and inspection data throughout the process, and automatically alarms in case of abnormalities.

[0072] In addition, efficiency can be improved through multi-station parallel inspection, or inspection accuracy can be optimized by adopting a disc-type secondary verification structure to adapt to different production needs.

[0073] This device achieves integrated automated operation, completely replacing manual inspection, sorting, and packaging processes, significantly reducing labor costs, and avoiding inspection errors caused by human operation, thus significantly improving production continuity and overall efficiency. The vision inspection unit adopts full-dimensional image acquisition, height adaptive adjustment, and synchronous supplementary lighting control, combined with a specially optimized AI algorithm based on convolutional neural networks, to accurately identify various defects. With the secondary verification design, it effectively reduces false detection and missed detection rates, ensuring product quality stability. At the same time, it enables traceability of the production process and data management. The integrated design of the equipment improves production efficiency and greatly saves space costs.

[0074] Example 2

[0075] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the workpiece 102 to be inspected can be rotated at an angle on the conveyor belt 101 to achieve 360° image acquisition and improve the detection accuracy.

[0076] Specifically, the conveyor belt 101 includes a belt layer 4001 sleeved on the surface, and a support plate 4022 is provided inside the belt layer 4001. The support plate 4022 is used to support the belt layer 4001 and the workpiece 102 to be inspected. A floating disk 4002 is provided on the belt layer 4001. When the conveyor belt 101 slides against the support plate 4022, the floating disk 4002 rotates relative to the conveyor belt 101, and at the same time drives the workpiece 102 to be inspected to rotate.

[0077] The belt layer 4001 has a rotating groove 4003, the rotating groove 4003 has a T-shaped ring 4004, the floating disk 4002 has a first sealing groove 4005, and the floating disk 4002 is rotatably disposed on the inner wall of the rotating groove 4003.

[0078] The T-shaped ring 4004 is rotatably mounted on the inner wall of the first sealing groove 4005, which is also a T-shaped groove, so that the floating disk 4002 can rotate on the inner wall of the first sealing groove 4005. At the same time, all the structural materials in this device are made of high wear-resistant and high-toughness PVC material, which has high tensile strength in the horizontal direction. When it moves to both ends of the conveyor belt 101, it can undergo elastic deformation and maintain a certain strength after changing to a horizontal state.

[0079] More preferably, a sealed chamber 4006 is formed between the floating disc 4002 and the rotating groove 4003. The sealed chamber 4006 is filled with lubricating fluid. A conical groove 4007 is also provided on the belt layer 4001. A conical block 4008 is slidably provided in the conical groove 4007. A protrusion 4009 is provided above the conical block 4008.

[0080] The conical groove 4007 is filled with negative pressure to fix the workpiece 102 under inspection by adsorption, preventing it from tipping over during rotation. At the same time, the placement posture of the workpiece 102 under inspection can be determined according to the magnitude of the negative pressure. When there is a gap at the bottom of the workpiece 102 under inspection, air enters and causes the negative pressure value to decrease. At this time, it is determined that the workpiece is not placed properly and an alarm is triggered.

[0081] More preferably, a first elastic element 4011 is provided between the outer wall of the bottom surface of the conical block 4008 and the rotating groove 4003, and a rotating shaft 4012 is also provided on the bottom surface of the conical block 4008. The rotating shaft 4012 rotates through the belt layer 4001 and extends to a section of the support plate 4022.

[0082] The support plate 4022 is provided with a slide rail 4013, and the rotating shaft 4012 is provided with a rotating wheel 4014 near the end of the support plate 4022. When the rotating wheel 4014 moves down with the rotating shaft 4012 and the protrusion 4009, it contacts and cooperates with the slide rail 4013.

[0083] Preferably, the rotating wheel 4014 and the slide rail 4013 can be coupled by a gear and rack to ensure a precise transmission ratio. In this case, the slide rail 4013 is a hard plastic rack and the rotating wheel 4014 is an elastic plastic gear that can deform to a certain extent and return to its original position.

[0084] More preferably, in other embodiments, the rotating shaft 4012 can also be driven by friction between the disc and the guide rail to reduce wear and increase service life; at the same time, the transmission end of the conveyor belt 101 can be driven by segmented transmission rollers, with gaps left between each transmission roller to facilitate the passage of the rotating wheel 4014.

[0085] More preferably, the outer wall of the conical groove 4007 has a synchronization groove 4015, the outer wall of the conical block 4008 is provided with a synchronization pin 4016, the synchronization pin 4016 is slidably disposed on the inner wall of the synchronization groove 4015, and the lower surface of the belt layer 4001 is provided with a figure-eight groove 4017 and a storage groove 4018 respectively.

[0086] Even better, since the components in this embodiment have a certain degree of elasticity, when the rotating wheel 4014 moves upward, it enters the receiving groove 4018 and undergoes elastic deformation, preventing damage caused by hard collision with the outer surface of the transmission roller and improving service life.

[0087] Among them, the cross section of the V-shaped groove 4017 is V-shaped with a smaller upper part and a larger lower part. When the conveyor belt 101 comes into contact with the drive roller, it bends and deforms. At this time, the upper part of the V-shaped groove 4017 expands more and the lower part expands less, forming a complete cylindrical cavity to prevent squeezing and collision with the rotating shaft 4012, and also to provide it with enough deformation space.

[0088] More preferably, one end of the slide rail 4013 is equipped with a drive cylinder, which can drive the slide rail 4013 to move when the conveyor belt 101 stops, so as to realize visual image acquisition and detection in a static state, and to detect the surface of complex workpieces.

[0089] Furthermore, after the workpiece 102 to be inspected is placed on the floating disk 4002, the downward pressing protrusion 4009 moves downward, and a gap is generated between the conical block 4008 and the conical groove 4007. The negative pressure fixes the workpiece 102 to be inspected, and at the same time drives the rotating wheel 4014 to move down and contact and fit with the slide rail 4013; thus, when no workpiece 102 to be inspected is placed, the rotating wheel 4014 and the floating disk 4002 do not rotate.

[0090] In summary, during use, after the workpiece 102 to be inspected is placed on the floating disk 4002 of the belt layer 4001 of the conveyor belt 101, its own gravity squeezes the protrusion 4009, causing the conical block 4008 to move downward, so that a gap is formed between the conical block 4008 and the conical groove 4007. The negative pressure is used to adsorb and fix the workpiece 102 to be inspected through the gap. At the same time, the downward movement of the conical block 4008 causes the rotating shaft 4012 to move downward synchronously, so that the rotating wheel 4014 at the end of the rotating shaft 4012 contacts and fits against the slide rail 4013 on the support plate 4022. When the conveyor belt 101 drives the belt layer 4001 to slide along the support plate 4022, the rotating wheel 4014 and the slide rail 4013 form a transmission engagement through gear rack and pinion or friction drive, thereby driving the rotating shaft 4012 to rotate. With the limiting linkage of the synchronous pin 4016 and the synchronous groove 4015, the floating disk 4002 is driven to rotate relative to the conveyor belt 101, ultimately driving the workpiece 102 to rotate 360°. If the workpiece does not need to move or if the surface of a complex workpiece needs to be inspected, the driving cylinder can drive the slide rail 4013 to move, realizing visual image acquisition when the workpiece is stationary. When the workpiece 102 is not placed, the conical block 4008 is reset under the action of the first elastic element 4011, the rotating wheel 4014 moves upward into the receiving groove 4018, and neither the floating disk 4002 nor the rotating wheel 4014 rotates, avoiding ineffective operation. When the conveyor belt 101 runs to the bends at both ends, the figure-eight groove 4017 forms an adaptation space through differentiated expansion to prevent the rotating shaft 4012 from being squeezed and collided. The elastic material components deform and reset synchronously to ensure operational stability.

[0091] The automated connection is achieved through gravity-triggered linkage of the workpiece 102 under inspection, which drives the workpiece 102 to complete a 360° full-surface rotation. Combined with the vision inspection unit, it thoroughly covers the workpiece with no blind spots in image acquisition, effectively avoiding missed detection of local defects and greatly improving the accuracy of inspection. The negative pressure adsorption design not only ensures stable fixation of the workpiece during rotation to prevent tipping and displacement, but also judges the placement posture of the workpiece by changes in negative pressure, and promptly alarms to remind of improper placement, further avoiding inspection errors. The accurate acquisition function in the static state can specifically meet the inspection needs of complex workpiece surfaces, expanding the application scenarios of the equipment.
