However, for irregularly-shaped keys, backshells and lens assemblies, the existing technology has significant defects: firstly, traditional vibrating discs or conveyors are difficult to realize posture calibration and accurate positioning of irregular materials, resulting in low feeding efficiency and easy material jamming; secondly, during the process of adhesive tape pasting, release paper removal and assembly fitting of irregular surfaces, there is a lack of reliable visual guidance and pressure control mechanism, which is prone to assembly defects such as position deviation and bubble residue; thirdly, when multiple processes are integrated, material information tracing (such as ReelID deduction) and signal communication between devices (such as cooperation with dispensing machines and curing ovens) rely on manual intervention, and full-process automatic closed-loop control cannot be realized.

[0032] Some embodiments of the present application will be described in detail below in combination with the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0033] At present, in the field of automatic assembly of electronic cigarette components, the automatic feeding, pasting and assembling technology of regular-shaped parts (such as regular-geometric-shaped keys, shells) is relatively mature. The existing equipment usually relies on standardized positioning structures (such as card slots, plane references) and simple mechanical grabbing methods to realize material processing. However, for irregularly shaped keys, back shells and lens assemblies, the existing technology has significant defects: first, traditional vibrating discs or conveyors cannot achieve posture calibration and precise positioning of irregular materials, resulting in low feeding efficiency and easy material jamming; second, during the process of adhesive tape pasting, release paper removal and component bonding of irregular surfaces, there is a lack of reliable visual guidance and pressure control mechanism, which can easily cause assembly defects such as position deviation and bubble residue; third, when multiple processes are integrated, material information tracing (such as ReelID deduction) and signal communication between devices (such as cooperation with dispensing machines and curing ovens) rely on manual intervention, and cannot realize full-process automatic closed-loop control.

[0034] The existing technical solutions are designed for regular feature components. For irregular shape components, there are still no effective solutions for the key technical problems such as multi-process automatic assembly, dynamic parameter adjustable pressure maintaining process, quality closed-loop control based on visual detection and full-process material information tracing. In particular, how to realize high-precision bonding of irregularly shaped keys, back shells and lenses, adhesive tapes without manual intervention, and integrate detection, data uploading and device communication functions, has become a technical bottleneck in the industry.

[0035] Therefore, there is an urgent need for a full-process automatic assembly method suitable for irregular components to solve the problems of low efficiency, poor precision and insufficient intelligence in the prior art.

[0036] To solve the above problems, please refer to Figures 1-2 An embodiment of the present application provides an automatic electronic cigarette key installation method. The automatic electronic cigarette key installation method can be realized by an electronic cigarette key automatic installation device, which can include a controller, such as a controller deployed on a single server or a server cluster. The controller can also be deployed on a handheld terminal, a notebook computer, a wearable device, or a robot, etc.

[0037] Specifically, as Figure 1 shown, the provided automatic electronic cigarette key installation method includes steps S101 to S104, which are described in detail as follows:

[0038] Step S101. Automatically feeding the irregularly shaped keys, taking the keys from the key material source, automatically feeding the key adhesive tape, taking the key adhesive tape from the key adhesive tape material source, pasting the key adhesive tape on the key, and maintaining the pressure of the pasted key and key adhesive tape.

[0039] Specifically, the automatic feeding and posture calibration adopts a feeding mechanism combined with a vibrating disc and a visual positioning system to process irregularly shaped keys. The vibrating disc arranges the keys in an orderly manner in the material channel through frequency conversion speed regulation. A high-precision CCD camera is arranged at the end to collect key profile images in real time. The key posture is determined based on image recognition algorithms such as edge detection and template matching. The key is adjusted to a preset grabbing posture (positioning accuracy ±0.3 mm) through a pneumatic switch or a rotating gripper. The key adhesive material source adopts a roll material form. A servo motor driven unwinding roller is used to cooperate with a tension sensor (accuracy ±1% FS) to monitor the adhesive tension in real time. When the tension fluctuation exceeds the threshold value, the motor speed is automatically adjusted to ensure that the adhesive is delivered to the material taking station at a constant tension (5-10 N).

[0040] The adhesive pasting and position control are realized by integrating an adsorption type gripper and a pressure sensor in the material taking head. The positioning reference (such as a feature bump or a groove) on the key surface is recognized by a visual guidance system (positioning accuracy ±0.2 mm) to accurately grab a preset length of key adhesive (error ±0.5 mm) and paste it to the key target area at a speed of 0.1-0.3 m / s. The pressure sensor feeds back the pressure value (controlled at 8-12 N) in real time during the pasting process to ensure that the adhesive is wrinkle-free and bubble-free.

[0041] The pressure maintaining process control is realized by a pressure maintaining mechanism using a servo electric cylinder to drive a pressure head. The surface of the pressure head is covered with an elastic buffer layer (Shore hardness 60±5A). When contacting the key, the pressure head is pressed to a preset pressure (5-15 N / mm 2 ) at a speed of 0.5 mm / s. The pressure maintaining time (adjustable between 500 ms and 2000 ms) is controlled by a timer. The parallelism of the pressure head is monitored by a displacement sensor during the pressure maintaining process (error ≤0.1 mm) to ensure that the adhesive is completely pasted to the key surface.

[0042] Step S102. The lens is automatically fed, the lens is taken out from the lens material source, the release paper on the key adhesive is removed, the lens is pasted to the key, the state of the lens and the key is checked by the image detection device to ensure that the lens and the key are assembled, the lens adhesive is automatically fed, the lens adhesive is taken out from the lens adhesive material source, the lens adhesive is pasted to the assembled component of the lens and the key, and the assembled component after pasting is pressure maintained.

[0043] Specifically, the lens feeding and release paper removal are realized by using a precision material disc or a vibrating hopper as the lens material source. The lens is sucked by a vacuum adsorption type lens taking head (suction force 5-8 N adjustable). A micro-CCD camera integrated in the material taking arm detects the position of the lens. The lens angle is adjusted based on a visual servo algorithm (such as PTP control) (accuracy ±0.5°) to ensure that the reference edge of the lens is aligned with the adhesive area of the key adhesive.

[0044] The release paper removing device is composed of a peeling roller and a winding motor. The peeling roller has an angle of 30° with the surface of the button tape, and the winding motor has a speed synchronized with the moving speed of the mechanical arm (error ≤5 mm / s). The electrostatic adsorption of the release paper is reduced by an electrostatic eliminator (ion air nozzle), so that the release paper is completely peeled off without residue.

[0045] The lens fitting and visual inspection are performed by fitting the lens to the adhesive area of the button tape at a speed of 0.05-0.1 m / s. After fitting, the assembled image is collected by a high-precision linear array CCD camera fixed above the station. The detection algorithm automatically identifies the offset of the lens edge and the button positioning mark (X / Y axis error ≤0.2 mm, angle error ≤1°), and calculates the bubble area of the fitting area (threshold ≤0.3 mm²). The unqualified product triggers the pneumatic rejection device (response time ≤200 ms).

[0046] The lens tape pasting and pressure maintaining are performed by the lens tape feeder equipped with a servo correction system (correction accuracy ±0.1 mm). The remaining length of the tape is monitored in real time by a laser ranging sensor (accuracy ±1 mm). The real-time coordinates of the material taking head combined assembly (updated dynamically by the visual positioning system) accurately cover the lens tape on the edge of the lens, with a coverage deviation of ≤0.3 mm. The pressure maintaining mechanism automatically switches the pressure parameters according to the lens material (PC / PMMA) (PC material pressure 10-15 N / mm 2 , PMMA material 8-12 N / mm 2 ). The pressure maintaining time is controlled by a timer (1000 ms ±100 ms).

[0047] Step S103. Automatically loading the irregular-shaped back shell, taking the back shell from the back shell source, removing the release paper on the lens tape, assembling the component with pasted lens tape on the back shell, and pressure maintaining the assembled back shell component; detecting the gap and step difference of the back shell component by using an image detection device.

[0048] Specifically, the back shell loading and three-dimensional positioning are performed by using a customized tray for the back shell source. Each tray is provided with a positioning groove (matching the outer shape of the back shell). The back shell is grabbed by a six-axis mechanical arm + elastic clamp jaw. The 3D visual sensor (accuracy ±0.1 mm) integrated at the end of the mechanical arm scans the inner cavity structure of the back shell, generates point cloud data and reconstructs a three-dimensional model. Based on the model matching algorithm, the component installation path is planned (avoiding an error of ≤0.2 mm).

[0049] The assembly embedding and pressure maintaining control is removed by the static adsorption type stripping device through the release paper on the lens tape, and the stripping force is controlled at 5-10 N to avoid damaging the tape; the mechanical arm embeds the assembly into the positioning groove of the rear shell at a speed of 0.2 m / s, and the insertion resistance is monitored in real time by the force control sensor (accuracy ±0.5 N) during the embedding process to prevent overpressure damage to the components; the pressure maintaining pressure head is equipped with a displacement sensor (resolution 0.01 mm), which ensures that the assembly and the rear shell have a matching gap of ≤0.15 mm, and the pressure maintaining pressure is automatically adjusted according to the material of the rear shell (ABS / PC) (ABS material 15-20 N / mm 2 , PC material 12-18 N / mm 2 ).

[0050] The gap and difference detection is realized by scanning the edge joint of the rear shell assembly by using a laser displacement sensor array (measurement accuracy ±0.05 mm), and the detection software automatically calculates the gap value (threshold value ≤0.2 mm) and the difference value (threshold value ≤0.1 mm), the detection data is bound with the product SN code, and is uploaded to the FF system in real time (upload delay ≤1 s), and the product exceeding the limit triggers an audible and light alarm and is marked for isolation.

[0051] Step S104. The detected rear shell assembly is automatically loaded into the fixture tray, and the fixture tray is conveyed to the next station of the glue process by the conveying device; when each assembly material is loaded, the material reel identification information is obtained, and the material is counted according to the material reel identification information after assembly is completed; the return of the fixture is realized, and signal communication with external equipment is established to realize information interaction with the glue dispenser and the curing oven.

[0052] Specifically, the finished product loading and unloading and transmission are realized by placing the detected rear shell assembly into the fixture tray with positioning pins by the mechanical arm, the tray conveying device adopts a ring guide rail + servo transplanting mechanism (positioning accuracy ±0.5 mm), and is conveyed to the glue process at a speed of 0.5 m / s, and the tray is positioned by the proximity switch to trigger the signal feedback to the control system, to ensure that the loading and unloading are synchronized.

[0053] Material information tracing and counting are realized by setting RFID readers or barcode scanners at each loading station, the ReelID information is automatically read when the material is put online and is associated with the production work order (response time ≤50 ms), and after each time the material is taken, the control system automatically deducts the remaining amount of the material reel according to the preset consumption parameters (such as 10 mm of tape length consumed per key) of the BOM single, and when the remaining amount is lower than the warning value (20% of the rated amount), the MES system pushes the material replacement reminder to the terminal device.

[0054] The clamp returns to the feeding station through an empty clamp through an independent return line, the speed of the return line is synchronized with the main line beat (error ≤2%), and the clamp is detected by an optical sensor during the return process. The device is equipped with an industrial Ethernet interface (PROFINET / Modbus TCP) to establish real-time communication with the dispensing machine and the curing oven, receive the glue remaining amount signal of the dispensing machine, and send the component in-place signal, realize multi-device collaborative control (communication delay ≤10ms), and form an automatic closed loop from assembly to dispensing and curing.

[0055] In some embodiments, the key material is taken out from the key material source while the key tape is automatically fed, including: adjusting the posture of the irregularly shaped key and accurately grabbing it through the combination of the vibrating disc, the visual positioning system and the gripper, and the key material source adopts a material tray with positioning grooves or a continuous conveying belt; when the key tape is automatically fed, the servo motor drives the tape roll to rotate, and the tension sensor keeps the tape conveying tension stable, so that the key tape moves synchronously with the material belt to the preset material taking position.

[0056] The posture adjustment and accurate grabbing of irregular keys are realized through the combination of the vibrating disc, the visual positioning system and the gripper, and the constant tension conveying of the key tape is realized through the servo motor and the tension sensor.

[0057] The key material source adopts a material tray with positioning grooves (suitable for small batches of multiple models) or a continuous conveying belt (suitable for large batch production), the vibrating disc adjusts the posture of the irregular key in the material channel through variable frequency speed regulation (50-200Hz adjustable), and a high-precision linear array CCD camera (resolution 12μm / pixel) is arranged at the end to collect key contour images in real time.

[0058] The visual positioning system identifies key feature points (such as bosses and notches) based on a template matching algorithm (such as Halcon's shape-based matching), calculates the deviation between the current posture and the target posture (angle error >5° triggers adjustment), adjusts the key to the preset grabbing posture through the pneumatic rotary gripper (rotation accuracy ±0.1°) or the dial mechanism, and the gripper adopts an adaptive elastic structure (clamping force 3-8N adjustable) to ensure stable grabbing of irregular edges.

[0059] The tape roll is driven by a servo motor (accuracy ±0.01mm / revolution), and a tension sensor (range 0-50N, accuracy ±0.5%FS) detects the tape tension in real time. When the tension fluctuation exceeds ±1N, the control system automatically adjusts the motor speed (response time ≤100ms) to ensure that the tape is conveyed to the material taking position with constant tension (positioning accuracy ±0.3mm), and the synchronous movement speed of the material belt matches the taking rhythm of the mechanical arm (0.1-0.5m / s adjustable).

[0060] In some embodiments, the taking out the key tape from the key tape material source and pasting the key tape to the key includes: separating a preset length of the tape from the key tape material source by a suction or clamping material taking head with a pressure sensor, identifying a positioning reference feature of the key by a visual guidance system, and controlling a mechanical arm to paste the key tape to the key surface at a preset angle and position, and monitoring the pasting pressure in real time by the pressure sensor and feeding back and adjusting during the pasting process.

[0061] The preset length of the tape is separated by the material taking head with the pressure sensor, the accurate pasting is achieved by the visual guidance, the pasting pressure is monitored in real time and feedback adjustment is made.

[0062] The tape taking and separating are achieved by the suction type (vacuum degree -80kPa±5kPa) or clamping type (clamping jaw stroke 0.5-10mm adjustable) structure of the material taking head, the micro pressure sensor (range 0-50N, resolution 0.1N) is integrated, the tape is separated according to the preset tape length (the rotation number of the feeding roller is controlled by the servo motor, error ±0.2mm), and the separation force is controlled at 5-15N to avoid the tape stretching and deformation.

[0063] The visual guidance system scans the key surface by the structured light camera (accuracy ±0.1mm), identifies the positioning reference feature (such as edge chamfer and positioning hole), generates the pasting coordinate system, and the mechanical arm (repeat positioning accuracy ±0.05mm) pastes the tape at the planned path (speed 0.1-0.3m / s) to control the pasting angle error within ±1°.

[0064] The pressure sensor collects the contact pressure in real time during the pasting process, when the pressure deviates from the preset value (8-12N) by more than ±1N, the control system automatically adjusts the Z-axis feed amount (resolution 0.01mm) of the mechanical arm to ensure that the tape and the key surface are in uniform contact and avoid local bubbles or wrinkles.

[0065] In some embodiments, the pressure maintaining for the pasted key and key tape includes: using an adjustable pressure cylinder or servo driven pressure head to maintain the pressure of the pasted key and tape assembly, the pressure maintaining pressure is collected in real time by the pressure sensor and compared with the preset pressure threshold, the pressure maintaining time is controlled by the timer, and the contact surface of the pressure head and the key surface maintain the parallelism error within the preset error range during the pressure maintaining process.

[0066] The adjustable pressure cylinder / servo pressure head is used for pressure maintaining, the pressure data is collected in real time and the pressure maintaining time is controlled to ensure that the parallelism error of the pressure head is within the preset range.

[0067] The pressure head driving mode of the pressure maintaining mechanism can be selected from a cylinder (pressure range 5-30 N, accuracy ±2 N) or a servo motor cylinder (pressure range 5-50 N, accuracy ±1 N), and the pressure head surface is covered with a silica gel buffer layer (thickness 2 mm, hardness Shore 70A). The contact area is adjusted according to the size of the key (the minimum contact area is greater than or equal to 20 mm 2 ).

[0068] The pressure sensor (integrated in the pressure head connecting rod, range 0-50 N, accuracy ±0.5% FS) collects pressure values in real time, and compares them with the preset threshold value (5-15 N / mm2, dynamically adjusted according to the adhesive viscosity coefficient). When the deviation exceeds ±5%, the pressure compensation (adjusting the pressure head feed amount ±0.2 mm) is triggered. The pressure maintaining time is controlled by a high-precision timer (resolution 1 ms), which supports 500 ms-2000 ms segmented setting (for example, the first segment is 500 ms high-pressure shaping, and the second segment is 1500 ms low-pressure pressure maintaining).

[0069] The parallelism control is realized by the pressure head installation flatness sensor (accuracy ±0.05 mm / m). The pressure head posture is automatically calibrated before pressure maintaining, and the parallelism error is monitored in real time during pressure maintaining, so as to ensure that the parallelism with the key surface is less than or equal to 0.1 mm (achieved by a four-axis linkage fine adjustment mechanism).

[0070] In some embodiments, the taking out of the lens from the lens material source, removing the release paper on the key adhesive tape, and pasting the lens on the key include: taking out the lens from the lens material disc or the vibrating hopper by vacuum suction type lens taking head, detecting the position and posture of the lens by an image recognition system and correcting the angle; removing the release paper on the key adhesive tape by the stripping roller cooperating with the release paper winding mechanism, and synchronizing the release paper stripping speed with the mechanical arm moving speed to accurately paste the corrected lens to the adhesive area of the key adhesive tape.

[0071] The lens is accurately pasted by vacuum suction and posture correction, and the release paper is removed synchronously by the stripping roller and the winding mechanism.

[0072] The lens taking, placing and correcting are realized by vacuum suction type lens taking head (suction aperture Φ1-5 mm adjustable, suction force 5-10 N) to take out the lens from the lens material disc (spacing ≥2 mm) or the vibrating hopper (frequency 50-150 Hz), a miniature CMOS camera (resolution 5 million pixels) integrated in the material taking head shoots the lens edge features, the position deviation (X / Y axis error >0.3 mm, angle error >1° triggers correction) is calculated by an image recognition algorithm, and the mechanical arm realizes posture correction by R-axis rotation (accuracy ±0.1°) and XY-axis compensation movement.

[0073] The release paper is removed by a peeling roller (diameter Φ50mm, surface coated with Teflon) at a 30° angle with the button tape. The release paper winding motor (speed 0-200rpm adjustable) provides real-time feedback on the speed through an encoder (resolution 1000 lines), synchronized with the movement speed of the mechanical arm (0.1-0.4m / s) (error ≤5mm / s). The peeling force is controlled at 3-8N (monitored by a tension sensor), ensuring that the release paper is not torn or left behind.

[0074] The lens is attached to the adhesive area at a speed of 0.05m / s after correction. The attachment pressure is controlled by the built-in pressure sensor in the material taking head (range 0-20N, resolution 0.2N) (5-8N). After attachment, the lens is left for 200ms to ensure stable adhesion.

[0075] In some embodiments, the lens and button state is checked using an image detection device to ensure that the lens and button are assembled, including: collecting the assembly image of the lens and button by a CCD camera fixed above the mechanical arm or on the side of the workbench. The image detection algorithm identifies the offset of the lens edge and the positioning mark of the button, as well as the bubble area of the attachment area. The detection results are transmitted to the control system in real time, and unqualified products trigger the automatic rejection mechanism.

[0076] Specifically, the CCD camera collects images to detect the offset and bubble area, and unqualified products are automatically rejected.

[0077] Image acquisition is performed by a CCD camera (resolution 12 million pixels, frame rate 30fps) fixed above the mechanical arm (working distance 200mm) or on the side of the workbench (tilted 45°). A telecentric lens (distortion rate <0.1%) is used, and the lighting method is bottom backlight (for transparent lenses) or ring side light (for non-transparent lenses), ensuring clear imaging of edge features.

[0078] The defect detection algorithm includes: offset detection: the lens and button positioning mark profile is extracted by edge detection (Canny operator), and the centroid coordinate deviation (X / Y axis error threshold ±0.2mm) and rotation angle deviation (threshold ±1°) are calculated; bubble detection: the attachment area is segmented using a region growing algorithm, and the bubble area (threshold ≤0.3mm 2 ) is calculated. A gray value fluctuation of more than 20% is considered a suspicious area. Unqualified product processing: the detection results are transmitted to the PLC control system (delay ≤50ms) in real time. The out-of-limit product triggers the pneumatic rejection valve (response time ≤30ms), which is isolated to the defective product collection box through a shunt conveyor belt (speed 0.5m / s). At the same time, the system records the defect type and occurrence time (time stamp accuracy 1ms).

[0079] In some embodiments, the automatic feeding of the lens tape, taking the lens tape from the lens tape source, pasting the lens tape to the assembled component of the finished lens and the key, and pressure holding the pasted component, comprises: feeding the lens tape by using a tape feeder with a servo correction function, detecting the remaining length of the lens tape by a laser ranging sensor; a material taking head combines with a visual positioning system to obtain the positioning coordinates of the component, accurately covers the lens tape on the edge area of the lens, and after pasting, a pressure head with a buffer mechanism is used for secondary pressure holding, and the pressure holding pressure is automatically switched according to the lens material.

[0080] Through servo correction tape feeding, laser ranging monitoring of the remaining amount, visual positioning and pasting, and switching of pressure holding parameters according to the lens material.

[0081] The servo correction feeder (correction accuracy ±0.1mm) calibrates the tape position in real time through an ultrasonic sensor (detection distance 50-300mm), and a laser ranging sensor (accuracy ±0.5mm) is installed on the side of the material roll and triggers a warning when the remaining length is less than 20m; the material taking head is equipped with a cutter (blade life ≥100,000 times), which cuts the tape according to the preset tape length (error ±0.5mm).

[0082] The visual positioning and pasting obtain real-time coordinates (positioning accuracy ±0.2mm) through the positioning marks (such as two-dimensional code, feature point) on the component through the visual positioning system, the mechanical arm pastes the lens tape with a circular trajectory (to avoid inertial impact) to cover the edge area of the lens (coverage width 3±0.3mm). Self-adaptive pressure holding is achieved by integrating a buffer mechanism (spring compression amount 0-5mm) in the pressure head, and the pressure parameter is preset as two groups: 10-15N / mm² for PC lens (hardness 90HRR), and 8-12N / mm² for PMMA lens (hardness 75HRR). 2 The parameter group is automatically switched by a code scanning gun reading the lens tray label, and the pressure holding time is uniformly set to 1000ms±100ms.

[0083] In some embodiments, the rear shell is taken from the rear shell source, the release paper on the lens tape is removed, the component assembled with the pasted lens tape is assembled to the rear shell, and the assembled rear shell component is pressure held, comprising: the irregular-shaped rear shell is grabbed by a material taking mechanism with elastic clamps, the inner cavity structure model of the rear shell is reconstructed by using a three-dimensional visual system, and the component installation path is generated; the release paper on the lens tape is removed by using an electrostatic adsorption type stripping device, the component is accurately embedded into the positioning groove of the rear shell by a mechanical arm after the release paper is removed, and the stroke of the pressure head is monitored by a displacement sensor during the pressure holding process to ensure that the fitting gap between the component and the rear shell is within the preset gap range.

[0084] The rear shell is grabbed by elastic clamps, a three-dimensional vision model generates an installation path, the release paper is stripped by electrostatic adsorption, and the displacement sensor monitors the fitting gap.

[0085] The rear shell grabbing and three-dimensional modeling are achieved by elastic clamps (silicone material, clamping surface arc matching rear shell edge) through force control sensor (range 0-50N, resolution 0.5N) to adaptively adjust the clamping force (8-15N) to avoid deformation; the 3D vision system (structure light principle, accuracy ±0.1mm) scans the inner cavity of the rear shell to generate an STL model, compares it with a standard model to generate an installation path (avoiding distance ≥0.5mm), and the path planning algorithm avoids sharp corner turning (minimum curvature radius 5mm).

[0086] The release paper removal and component embedding are achieved by the electrostatic adsorption stripping device (voltage ±5kV adjustable) to contact the surface of the release paper, with an adsorption force of 5-10N to ensure complete stripping, and the stripping angle is controlled within 45°±5°; the mechanical arm embeds the component at a speed of 0.2m / s, and the displacement sensor (range 0-50mm, resolution 0.01mm) monitors the travel of the pressure head during embedding, and when the fitting gap is >0.15mm, it automatically retreats and recalibrates the positioning.

[0087] The pressure maintaining and gap monitoring are achieved by the pressure maintaining pressure head equipped with a linear guide (straightness 0.02mm / m), which monitors the sinking amount of the component in real time during pressure bonding to ensure that it is flush with the positioning surface of the rear shell (height difference ≤0.1mm), and the pressure maintaining pressure is automatically switched according to the material of the rear shell (ABS / PC) (ABS: 15-20N / mm², PC: 12-18N / mm²). 2 The pressure maintaining time is 800ms±50ms.

[0088] In some embodiments, when each assembly material is fed, the material roll identification information is obtained, and the material is deducted according to the material roll identification information after assembly is completed, which comprises: setting an RFID reader or a barcode scanner at the feeding station to read the ReelID information of the material roll in real time and associate it to the current production work order; after each material is taken, the control system automatically deducts the remaining amount of the corresponding material roll according to the preset unit consumption parameter, the deduction result is stored in the production management system, and a material replacement prompt is triggered when the remaining amount of the material roll is lower than the warning value.

[0089] The material roll identification is scanned by RFID / barcode, the work order is associated, and the consumption is automatically deducted, and the remaining amount warning triggers the material replacement prompt.

[0090] The identification reading is associated with the work order by setting an RFID reader (working frequency 13.56 MHz, reading distance 5-10 cm) or a two-dimensional code scanner (resolution ≥0.1 mm / pixel) at the feeding station. When the material is put online, the ReelID, batch number, material specification and other information are automatically read, and the data are bound to the current production work order (including product model, order quantity, BOM single) through the MES interface (data verification time ≤2 s).

[0091] The automatic deduction logic is preset by the control system according to the BOM single consumption parameters (such as 10 mm of key adhesive tape and 8 mm of lens adhesive tape consumed per assembly of 1 product), and the deduction amount is calculated in real time (accuracy ±0.1 mm) after each use of the material. The remaining amount = initial amount - cumulative consumption amount, and the deduction result is stored in the database (storage delay ≤100 ms) in synchronization. The system supports historical data tracing (tracing period ≥2 years).

[0092] The remaining amount warning and material replacement prompt are preset with a warning value of 20% of the rated amount (configurable). When the remaining amount < warning value, the system prompts material replacement through a three-color light (yellow warning), a buzzer (frequency 1 kHz) and a pop-up window of the MES system. The material replacement process is confirmed by scanning the code (error-proof mechanism) to ensure correct connection of the new and old material roll information.

[0093] In some embodiments, the pose recognition and self-calibration of complex key profiles are realized by replacing the traditional template matching with a convolutional neural network (CNN) + dynamic programming algorithm, and the vibration disc jamming risk is predicted by combining digital twin technology.

[0094] The deep learning pose recognition is realized by constructing a key pose data set (containing multiple point cloud / image data at different angles), training a lightweight CNN model (such as MobileNetV3), recognizing key profile feature points in real time (accuracy ≥99.2%), and outputting the optimal grabbing pose angle (accuracy ±0.3°). The recognition blind area of traditional algorithms for irregular keys with multiple curvatures is solved. The visual system integrates an edge computing module (Nvidia Jetson AGX), and the image inference delay is ≤15 ms. The system supports fast switching of more than 200 irregular key models (model loading time <5 s).

[0095] The dynamic programming self-calibration strategy is realized by automatically planning the gripper adjustment path when the CNN recognizes that the key pose deviation is >2°. The algorithm matches the historical optimal adjustment action sequence through dynamic time warping (DTW) algorithm, and drives the pneumatic gripper to complete the pose correction with the minimum energy consumption (adjustment time ≤800 ms). Compared with the traditional fixed logic adjustment, the efficiency is improved by 40%.

[0096] Digital twin predictive maintenance installs acceleration sensors on the vibrating tray (sampling frequency 1 kHz), collects vibration amplitude and frequency data, inputs them into the LSTM neural network, constructs a digital twin model of the device state, predicts the risk of material channel blockage 4 hours in advance (early warning accuracy ≥95%), and automatically adjusts the vibrating tray frequency (step size ±5 Hz) for preventive intervention.

[0097] In some embodiments, by introducing a deep reinforcement learning (DRL) algorithm, the bonding pressure parameters are dynamically optimized based on real-time feedback of the quality of the bonding, and closed-loop control is achieved in combination with machine vision defect classification.

[0098] The reinforcement learning control architecture defines a state space including 12-dimensional state parameters such as the current pressure value, bonding speed, key material quality (obtained by scanning the code), and historical defect rate, an action space including pressure adjustment steps (±0.5N) and bonding angle compensation (±0.5°), and a reward function that assigns a positive reward when there is no defect after bonding, with negative feedback based on the area of bubbles and the edge offset. The PPO (Proximal Policy Optimization) algorithm is used to train the controller, and 2000+ bonding samples are generated per shift for online updating of the policy. After the pressure parameters converge, the defect rate during bonding is reduced by 35%.

[0099] The defect classification and feedback closed loop adds a YOLOv8 defect classification model in the visual inspection link to identify three types of defects (mAP@0.5≥92%) in real time, including "edge wrinkles", "local bubbles", and "offset out-of-tolerance". The classification results are input into the reinforcement learning system as the basis for policy updates, enabling targeted pressure compensation for different defect types (e.g., a +1.5N adjustment for wrinkle defects).

[0100] Multi-modal sensor fusion integrates a six-dimensional force sensor (resolution 0.1N·m) and an infrared temperature sensor (accuracy ±1℃) in the takeout head, and combines pressure sensor data to construct a bonding force-temperature-defect correlation model. The XGBoost algorithm is used to predict the optimal bonding pressure in real time (adapt to different batches of adhesive viscosity fluctuations, with a viscosity coefficient prediction error of ≤3%).

[0101] In some embodiments, PointNet++ point cloud deep learning algorithm is used to extract features of the inner cavity of the rear shell, intelligent path planning algorithm is used to solve the rapid adaptation of multiple models of rear shells, and an anomaly detection algorithm is introduced to improve the robustness of gap detection.

[0102] Point cloud feature intelligent matching generates point cloud data by scanning the inner cavity of the rear shell with a 3D vision sensor (accuracy ±0.08 mm), inputs the lightweight PointNet++ model to extract geometric features (such as positioning bosses and avoidance grooves), and matches the features with 300+ rear shell models in the process database (matching time ≤200 ms), to automatically generate the corresponding component embedding path (including 6-axis robot joint angle parameters). For new models of rear shells, "fast teaching without drawings" is supported: manual teaching of three feature points can trigger the algorithm to automatically complete the path (completion error ≤0.15 mm), and the changeover time is shortened from 30 minutes to 5 minutes.

[0103] Intelligent path planning and force control fusion uses A* algorithm to optimize the embedding path, avoids the interference area of the station, and minimizes the motion distance (path length is reduced by 25%); during embedding, the force control sensor data is input into the adaptive impedance controller (stiffness parameter real-time adjustment range 5-50 N / mm), and when the resistance suddenly changes (>20 N), the "trial-retreat-correction" strategy is triggered (response time ≤50 ms) to avoid hard contact damage to the components.

[0104] Gap detection anomaly detection establishes a Gaussian mixture model (GMM) of the standard component gap distribution, detects the data input into the One-Class SVM anomaly detector in real time, triggers secondary measurement for gap values exceeding the 3σ range (false positive rate ≤0.1%), and combines the secondary confirmation of the vision system to solve the false positive problem of traditional threshold detection for material differences (such as different light transmittances of ABS / PC).

[0105] In some embodiments, by constructing a material digital thread (Digital Thread), optimizing the material deduction logic through spatiotemporal sequence prediction algorithm, and combining reinforcement learning to realize dynamic allocation of equipment energy consumption.

[0106] Digital thread driven material traceability binds a unique digital thread to each material roll, integrates RFID data, work order information, and consumption log (timestamp accuracy 1 ms), predicts the material consumption trend (future 2-hour usage prediction error ≤5%) through the spatiotemporal Transformer model, and automatically triggers the AGV feeding request (response time ≤30 s) when the predicted remaining amount < warning value, to realize "zero inventory" material change.

[0107] The deduction logic introduces a dynamic unit consumption correction algorithm to dynamically update the BOM unit consumption parameters (such as triggering correction when the actual unit consumption fluctuation >10%, with a correction period of 10 minutes) based on real-time yield and defect rate data, to solve the material settlement deviation problem caused by traditional fixed unit consumption (error reduced from ±8% to ±2%).

[0108] Multi-device energy consumption optimization scheduling establishes a device energy consumption digital twin model, inputs real-time load of each station (vibrating disc speed, mechanical arm movement frequency, etc. 15-dimensional parameters), and optimizes power distribution strategy through deep Q network (DQN): within the allowable range of production rhythm, dynamically adjusting the servo motor power of non-critical stations (such as standby roll pre-acceleration) (energy-saving mode reduces energy consumption by 18%), while ensuring Cycle Time fluctuation ≤50ms.

[0109] Intelligent error-proofing and quality traceability verifies the compatibility of materials, work orders, and equipment through graph neural network (GNN) when materials are online (such as checking whether the adhesive tape adhesion matches the current model), the compatibility atlas contains 2000+ association rules, the verification time is <100ms, and the error-proofing coverage rate is improved from 95% to 99.8%; when quality problems are traced, the material digital thread can be used to trace back to specific equipment parameters (such as the pressure holding pressure fluctuation period corresponding to a batch of defective products).
