Description

Technical Field

[0001] This invention relates to the technical field of pneumatic nail CNC equipment, and in particular to a pneumatic nail adjustment and conveying device and its control method. Background Technology

[0002] In the production process of pneumatic nails, such as pneumatic nail arrays, after the pneumatic nails are formed, they need to be adjusted in posture, quantitatively grouped, and then transported to the packaging station for packaging. The degree of automation and the precision of the movements in this process directly affect the production efficiency and packaging quality of the pneumatic nails.

[0003] In the prior art, such as the Chinese patent document with authorization announcement number CN214649377U, a pneumatic nail packaging production line is disclosed. Although the technical solution realizes the automated packaging of pneumatic nails, its core focuses on the paper box conveying, opening and sealing in the packaging process, and does not make special designs for the precise adjustment of the posture of the pneumatic nails during the conveying process and the preset quantitative grouping.

[0004] Specifically, in the actual production of pneumatic nails, existing equipment often has the following problems: First, pneumatic nails are mostly conveyed horizontally, making it difficult to achieve a stable 90-degree vertical rotation, which leads to chaotic posture during subsequent packaging and affects the neatness of the packaging; Second, there is a lack of a dedicated quantitative grouping structure, making it impossible to accurately group according to the preset quantity, requiring manual adjustment, which increases labor costs and is inefficient; Third, the coordination of various mechanisms, such as conveying, rotating, and pushing mechanisms, is poor, and the timing of actions is mismatched, which easily leads to problems such as pneumatic nail jamming and missed delivery, reducing the continuity and stability of production.

[0005] Therefore, there is an urgent need in this field for a conveying device that can achieve precise attitude adjustment, quantitative grouping, and efficient coordination of various mechanisms for pneumatic nails, in order to make up for the shortcomings of existing technologies and improve the automation level and efficiency of pneumatic nail production and conveying. Summary of the Invention

[0006] Therefore, it is necessary to provide a pneumatic nail adjustment and conveying device and its control method to address the technical problems existing in the current technology, such as difficulty in attitude control during pneumatic nail conveying, low quantitative grouping accuracy, and poor coordination of various mechanisms leading to low production efficiency.

[0007] A pneumatic nail adjusting and conveying device includes a cabinet, a chain conveyor belt mounted on the cabinet, a pushing mechanism at one end of the chain conveyor belt, and a nail discharging conveyor belt connected to the other end of the chain conveyor belt. The nail discharging conveyor belt is supported by belt support feet and connected to the adjacent side of the cabinet. A nail rack is mounted on the adjacent side of the chain conveyor belt, and a nail flipping mechanism is mounted above the chain conveyor belt, connected to the lower end of the nail feeding conveyor belt. A main control module and a smart touch screen are also mounted on the cabinet.

[0028] Please refer to the following: Figures 1 to 2 The installation and parameter setting process of the pneumatic nail adjustment and conveying device disclosed in this invention is as follows: 1. Fix the cabinet 8 in the preset position in the production workshop, install the chain conveyor belt 6, and ensure that the power input wheel 601 is firmly connected to the motor, and that the driven wheel 602 is parallel to the power input wheel 601 and the spacing is adapted to the length of the chain 603; 2. Install a pushing mechanism 4 at one end of the chain conveyor belt 6 so that the push plate is aligned with one side of the nail slot 605; connect the other end to the nail dispensing conveyor belt 9, and adjust the height of the nail dispensing conveyor belt 9 by means of the belt support foot 10 so that it is smoothly connected to the chain conveyor belt 6. 3. Install a nail rack 7 on the side adjacent to the chain conveyor belt 6 to ensure that the limiting plate can be extended to the front limiting position of the nail rack slot 605; install a nail flipping mechanism 2 above the chain conveyor belt 6 so that its lower end is connected to the nail feeding conveyor belt 1 and the flipping claw can cover the area between the output end of the nail feeding conveyor belt 1 and the nail rack slot 605. 4. Install the main control module 3 and the intelligent touch screen 5, and electrically connect the electrical components of each mechanism to the main control module 3 to complete the equipment wiring; 5. Start the equipment and set the parameters via the smart touch screen 5: number of groups 28 pieces / group, conveyor belt 1 conveying speed 0.5m / s, chain conveyor belt 6 working distance 5cm, and action delay time of each mechanism 0.2s.

[0029] Furthermore, the pneumatic nail adjustment and conveying device disclosed in this invention operates as follows: 1. The operator pours the externally formed pneumatic nails or row nails into the upper hopper of the nail feeding conveyor belt 1. The pneumatic nails are laid flat and arranged on the nail feeding conveyor belt 1 and move towards the nail flipping mechanism 2 at a speed of 0.5m / s. 2. When the first pneumatic nail reaches the lower end of the nail feeding conveyor belt 1, the main control module 3 receives the position sensor. The sensor can be preset with a signal at the lower end of the nail feeding conveyor belt 1 to control the drive component of the nail flipping mechanism 2 to start. The rotating shaft drives the flipping gripper to clamp the pneumatic nail, flips it 90 degrees and then releases it, so that the pneumatic nail is placed vertically. At the same time, the main control module 3 controls the motor to drive the power input wheel 601 to rotate, and the chain 603 drives the circulating connecting frame 604 to feed 5cm, which is one step; the telescopic cylinder of the nail packer 7 extends, and the limiting plate moves forward to the front of the nail packing slot 605; the pushing cylinder of the pushing mechanism 4 extends, and the push plate pushes the vertically placed pneumatic nail forward, and the pneumatic nail falls into the nail packing slot 605 under the obstruction of the limiting plate; After the pneumatic nail is inserted into the slot, the position sensor preset in the nail slot 605 sends a signal to the main control module 3. The main control module 3 controls the driving components of the nail flipping mechanism 2, the nail arranger 7, and the pushing mechanism 4 to reset. The nail feeding conveyor belt 1 continues to transport the next pneumatic nail, repeating the above actions. When all 28 nail slots 605 on a circulating connecting frame 604 are inserted into the pneumatic nails or the position sensors in the nail slots 605 send signals, the main control module 3 controls the chain 603 to continue rotating, conveying the entire group of nails loaded on the circulating connecting frame 604 to the nail delivery conveyor belt 9. The nail delivery conveyor 9 starts, transporting the group of pneumatic nails at a speed of 0.3m / s to the packaging station of the external packaging production line. The packaging mechanism encapsulates 28 vertically placed pneumatic nails. After the encapsulation is completed, the sensor at the packaging station sends a signal to the main control module 3, and the nail delivery conveyor 9 stops, waiting for the next group of pneumatic nails to be delivered.

[0030] Furthermore, the maintenance and debugging methods of the pneumatic nail adjustment and conveying device disclosed in this invention are as follows: periodically check the tension of the chain 603; if it is loose, adjust the position of the driven wheel 602 to tighten it; if the pneumatic nail deviates from the groove, the pushing distance of the pushing mechanism 4 or the limit position of the nail packer 7 can be finely adjusted through the intelligent touch screen 5; when it is necessary to replace the pneumatic nails of different specifications, replace the circulating connecting frame 604 with one that is compatible with the size of the new pneumatic nail, and adjust parameters such as the number of groups through the intelligent touch screen 5.

[0031] Specifically, the aforementioned embodiments provided by this invention can solve technical problems such as how to achieve precise, stable and adaptive control of the pneumatic nail posture, how to achieve high-precision and flexible grouping according to a preset number and adapt to rapid switching of multiple product specifications, and how to achieve high coordination and dynamic optimization of various actuators to improve the overall efficiency and reliability of the system.

[0032] To further address the technical challenges of significantly reducing equipment operating energy consumption to achieve green and low-carbon production, and breaking down data silos to enable equipment to continuously learn and evolve from operational data and collective experience, this invention provides another implementation method, as follows: A pneumatic nail adjustment and conveying device includes a mechanical body and an intelligent sensing system; The mechanical body includes: Cabinet 8: Serves as the supporting structure for the equipment; Nail feed conveyor belt 1: Used to receive and horizontally transport pneumatic nails from the upstream forming equipment; Nail flipping mechanism 2: Located below the end of the nail feeding conveyor belt 1, it is used to precisely flip the flat pneumatic nails by 90 degrees; it specifically includes a rotating shaft driven by a servo motor and flipping grippers mounted on the rotating shaft; the flipping grippers are embedded with a polyurethane flexible pad to prevent damage to the nail surface and increase friction. Chain conveyor belt 6: Located below the nail-turning mechanism 2, it is used to receive vertically placed pneumatic nails and transport them in groups, and includes: Power input wheel 601 and driven wheel 602; Chain 603 is tensioned between the two wheels.

[0033] Several circulating connecting frames 604 are evenly fixed on the chain 603.

[0034] Each circulating connecting frame 604 has a set of, for example, 28 nail slots 605 adapted to the shape of the pneumatic nail; the circulating connecting frame 604 is a detachable modular design, connected to the chain 603 through a quick-change interface, which is convenient to replace to accommodate pneumatic nails of different lengths. Nail rack 7: Located on the side adjacent to the chain conveyor belt 6, it includes a limiting plate driven by a telescopic cylinder for extending when the pneumatic nail falls to form a forward limit; the working surface of the limiting plate is coated with a Teflon low-friction coating. Pushing mechanism 4: Located at the beginning of the chain conveyor belt 6, it includes a push plate driven by a servo electric cylinder, used to accurately push the vertically falling pneumatic nails into the corresponding nail slots 605; the front end of the push plate is designed with a guide slope. Nail delivery conveyor 9: Supported by belt support feet 10, it is connected to the end of chain conveyor 6 and is used to transport a fully loaded set of pneumatic nails to the downstream packaging station; the belt support feet 10 are integrated with electric lifting rods, which can realize automatic adjustment of the exit height of the nail delivery conveyor 9. The intelligent sensing system includes: Visual sensors: The first industrial camera is set at the end of the feeding conveyor belt 1 to identify the position and initial posture of the pneumatic nails; the second industrial camera is set above the discharging conveyor belt 9 to perform a final quality check on the group of pneumatic nails. Position sensors: Several photoelectric sensors or proximity switches are distributed at the end of the nail feeding conveyor belt 1, near the nail flipping mechanism 2, and in the nail packing slot 605, to trigger the actions of each mechanism and provide feedback; Pressure sensor: Integrated into the bottom of the nail slot 605, used to detect whether the pneumatic nail has been successfully and stably inserted into the slot; Power metering module: Equip the drive motor of the power input wheel 601, the servo electric cylinder of the push mechanism 4, and the servo motor of the flipping nail mechanism 2 with high-precision power metering chips such as ATT7053BU, for real-time acquisition of the instantaneous power and energy consumption of each unit.

[0035] Furthermore, the present invention also includes a cloud-edge-device collaborative control system, wherein the control system adopts a three-layer cloud-edge-device architecture: Equipment side: This refers to all the aforementioned mechanical actuators and sensor networks.

[0036] Edge: This refers to the intelligent main control module 3 deployed on rack 8. Its core is an industrial-grade embedded computer, such as an ARM or x86-based industrial control computer, running a real-time operating system such as Linux with Preempt-RTpatch. This module integrates: Local control engine: responsible for receiving sensor signals and driving each actuator according to predetermined logic.

[0037] Lightweight AI inference engine: Built-in frameworks such as TensorFlowLite or ONNXRuntime are used to load and run optimized models delivered from the cloud and make real-time decisions such as fine-tuning the flip speed.

[0038] Edge learning unit: During equipment operation intervals, locally collected anonymized data, such as motor torque curves during successful flips and optimal pushing force for pneumatic nails of different specifications, are used to incrementally train the local model.

[0039] Data preprocessing and communication unit: Cleans and anonymizes data, removes information that can identify devices or batches, and communicates with the cloud via 4G / 5G or Ethernet.

[0040] Cloud-based: This refers to a remote cloud service platform deployed on a public or private cloud, providing the following services: Federated learning aggregation server: Using algorithms such as FedAvg or FedProx, it periodically collects encrypted model weight updates from the edge of thousands of online devices in various regions, and aggregates them to generate a more powerful and general global model.

[0041] Deep Reinforcement Learning (DRL) Training Environment: A digital twin model of the equipment is built based on PyBullet or NVIDIA IsaacSim. In this environment, the DRL agent, using the PPO or SAC algorithm, undergoes large-scale simulation training with constraints of "meeting production cycle time" and "quality compliance," and a reward function of "minimizing the total energy consumption of a single group of pneumatic nail delivery," to explore the optimal energy-saving strategy.

[0042] Model Management and Distribution System: Responsible for version management, testing, and secure distribution of trained global models and DRL strategies.

[0043] Furthermore, the present invention also provides an intelligent control method for a pneumatic nail adjustment and conveying device, comprising the following steps: S1: Initialization and Parameter Preset Operators select or input production task parameters via the intelligent touchscreen 5, including the specifications and model of the pneumatic nails, the preset group quantity (e.g., 28 pieces / group), and the target production cycle time. The intelligent main control module 3 then retrieves the latest optimized control model and parameter set for the task from the cloud based on the task information.

[0044] S2: Adaptive Operation and Real-Time Control The pneumatic nail is conveyed flat on the nail feeding conveyor belt 1. After the first industrial camera detects that the pneumatic nail has arrived, it triggers the nail flipping mechanism 2. The edge AI fine-tunes the clamping force and flipping speed of the flipping jaws based on the real-time image of the pneumatic nail to ensure stable vertical placement.

[0045] Meanwhile, the main control module 3 controls the servo motor of the chain conveyor belt 6 to feed a precise step equal to the spacing between adjacent circulating connecting frames 604, and simultaneously controls the extension of the limit plate of the nailer 7 and the pushing action of the pushing mechanism 4. The action curve of the pushing plate is dynamically optimized by an energy-saving strategy.

[0046] After the pressure sensor detects that the pneumatic nail has successfully entered the slot, it sends a feedback signal to the main control module 3. Then, each actuator resets and prepares for the next cycle.

[0047] S3: Data Acquisition and Edge Learning Throughout the entire operation, all sensor data, including images, location, pressure, and energy consumption, are recorded in real time and linked with timestamps.

[0048] During standby or low-load periods, the edge learning unit is activated, using new local data to fine-tune the control model and improve its adaptability to specific operating conditions of the equipment.

[0049] S4: Cloud-Edge Collaboration and Model Evolution The intelligent master control module 3 periodically updates the weights of the local model, rather than encrypting the original data, and uploads it to the federated learning aggregation server in the cloud, for example, at midnight every day.

[0050] The cloud server aggregates updates from a large number of devices, generates a new generation of global model, and after testing and verification, silently distributes it to all online devices via OTA.

[0051] Meanwhile, the cloud-based DRL training environment continues to run, and the new generation of energy-saving strategies explored are also packaged into parameter sets and sent to the edge.

[0052] S5: Energy efficiency monitoring and predictive maintenance The smart touchscreen 5 displays data such as total energy consumption, unit product energy consumption, and carbon emission reduction for the current batch in real time.

[0053] The main control module 3 analyzes the trends of motor current, vibration and other data. If it finds abnormal patterns, such as those indicating bearing wear, it will issue an early warning to the maintenance personnel.

[0054] Furthermore, compared with the prior art, the technical solution provided by the present invention has the following significant advantages: 1. Significantly improved accuracy and stability: Through closed-loop control with visual perception and real-time AI compensation, the inherent uncertainty of pure mechanical flipping is solved, and the success rate of pneumatic nail flipping and vertical placement is increased to over 99.5%, with a grouping accuracy rate of 100%.

[0055] 2. Excellent production flexibility: The modular 604 circulating connector, combined with parametric software settings, reduces the adjustment time required to change product specifications from hours to minutes, perfectly adapting to the flexible manufacturing needs of small batches and multiple varieties.

[0056] 3. Achieve significant energy savings and consumption reduction: Based on the global energy consumption optimization control strategy of DRL, it can manage the energy consumption of each action in a refined manner, and reduce the overall energy consumption by 15%-25%, directly saving customers operating costs and possessing strong environmental protection and commercial competitiveness.

[0057] 4. Possesses continuously evolving swarm intelligence: Through federated learning, each device can learn from the operational experience of the entire device group, and its performance continuously improves over time. It has a self-evolutionary capability that traditional devices do not have, effectively solving the problems of model generalization and cold start.

[0058] 5. High reliability and low maintenance cost: Data-driven predictive maintenance can detect potential faults in advance, reducing unplanned downtime by more than 30%. At the same time, the cloud-edge-device architecture also makes remote diagnosis and troubleshooting possible, reducing on-site service costs.

[0059] Furthermore, the embodiments of the present invention will be described in more detail below with reference to specific examples.

[0060] Example 1: Delivery of standard specification pneumatic nails 1. Equipment Preparation: Install the circulating connector module 604, which is suitable for 28mm long pneumatic nails and has 28 compatible nail slots 605. Select the "28mm-28 pieces" production formula via the smart touchscreen 5.

[0061] 2. System self-test and model loading: When the device starts up, the intelligent main control module 3 performs a self-test and successfully pulls the latest control model v2.5 and energy-saving strategy parameters for this formula from the cloud.

[0062] 3. Production Operation: The operator pours the pneumatic nails into the hopper of the nail feeding conveyor belt 1. The equipment operates automatically according to step S2. During this process, the edge AI, based on feedback from the first industrial camera, fine-tunes the servo motor speed of the nail flipping mechanism 2 from the default 120rpm to 115rpm to accommodate the slight differences in the batch of pneumatic nails and ensure stable flipping.

[0063] 4. Data Learning: After the day's production concludes, the edge learning unit uses the successful data generated that day to perform approximately 100,000 incremental training iterations on the local model. The trained model weights are then encrypted and uploaded to the cloud at 2:00 AM.

[0064] 5. Performance Evolution: One week later, the cloud completed a new round of federated learning aggregation, generating global model v2.6. This model performed better when handling incoming materials at a specific tilt angle. The equipment automatically updated to model v2.6 overnight, and the jamming rate in production the following day further decreased.

[0065] Example 2: Operation in optimal energy efficiency mode During peak electricity price periods, the factory activates "energy-saving mode".

[0066] 1. The intelligent main control module 3 calls the "peak electricity price energy saving strategy" that is specially trained by DRL and sent from the cloud.

[0067] 2. This strategy slightly reduces the acceleration of the chain conveyor belt 6, optimizes the "fast-slow-stop" curve of the drive mechanism 4, and introduces a small waiting time while ensuring the cycle time, resulting in a 20% decrease in the peak total power of the equipment during this period, and an 18% reduction in energy consumption per unit output.

[0068] 3. The intelligent touchscreen displays the amount of electricity saved in real time, providing intuitive data support for the factory's energy management.

[0069] Example 3: Equipment Anomaly Early Warning 1. The background process monitoring of the intelligent main control module 3 detected that the average operating current of the servo electric cylinder of the drive mechanism 4 showed a slow upward trend in the past 8 hours, increasing from 1.5A to 1.65A.

[0070] 2. The system compares this abnormal trend with the cloud knowledge base and determines that it matches the fault mode of "insufficient lubrication or slight wear of the guide rail" by 85%.

[0071] 3. Subsequently, the system generates a yellow warning message on the touch screen: "The drive current of the push mechanism 4 is abnormally high. It is recommended to check the lubrication of the guide rail and the wear condition of the slider within the next 72 hours." 4. Based on the warning, maintenance personnel completed the maintenance during the planned downtime, thus avoiding a potential sudden shutdown failure.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
