[0007] Therefore, there is an urgent need in the industry for a better way to solve the above problems. Summary of the Invention

[0008] In view of this, the present invention provides an intelligent storage management system for SMT production line carriers, which realizes the efficient storage, dynamic scheduling and full life cycle management of carriers through the cooperation of automated equipment and intelligent control modules. The technical solution of the present invention is as follows:

[0009] The present invention discloses an intelligent storage management system for SMT production line carriers, which includes an automatic barcode scanning system, an intelligent incoming material distribution device, an automatic bin shifting device, an automatic reverse pushing device, an intelligent control system, an intelligent warehouse management system, and an intelligent energy management module; the automatic barcode scanning system includes an industrial control computer, an industrial camera, and recognition software, the industrial control computer collects images through the industrial camera, and the recognition software analyzes the image information; the intelligent incoming material distribution device includes a modular conveying device, a pneumatic blocking device, a lifting mechanism, and an electric forward pushing mechanism; the automatic bin shifting device includes a bin rack and a bidirectional shifting driving mechanism, and the bidirectional shifting driving mechanism is arranged below the bin rack; the automatic reverse pushing device includes a lifting platform and a bidirectional push rod mechanism, and the lifting platform is connected to the bidirectional push rod mechanism; the intelligent control system includes a main control PLC and a distributed I / O module, the main control PLC is configured to coordinate the action timing of each hardware module, and the distributed I / O module is configured to be connected to sensors and actuators through industrial Ethernet; the intelligent warehouse management system is configured to establish a digital twin of the carrier and realize three-dimensional coordinate binding; the intelligent energy management module includes an energy consumption monitoring terminal and a dynamic voltage regulating controller, the energy consumption monitoring terminal is installed on the power supply lines of each motor and pneumatic component, and the dynamic voltage regulating controller automatically adjusts the motor drive voltage.

[0010] Specifically, in the above technical solution, in combination with the carrier barcode and visual positioning, a unique digital twin is generated, and the three-dimensional coordinates (X / Y / Z accuracy) are real-time bound to the physical position of the bin. Secondly, a time series database is used to store the changes in the carrier state, supporting millisecond-level updates; a relational database maps the logical relationship of the bins to realize the triple association of "bin-carrier-work order". Then, it supports fault-tolerant retrieval (such as partial barcode missing, spelling mistakes), and the query hit rate is increased to 99.8%.

[0011] Specifically, it includes the following steps:

[0012] S1. The carrier enters the automatic barcode scanning system, and the automatic barcode scanning system obtains data and uploads the data to the intelligent control system;

[0013] S2. The intelligent control system synchronously issues coordinate instructions and distribution instructions;

[0014] S3. The intelligent warehouse management system uploads energy consumption data to the intelligent energy management module;

[0015] S4. The intelligent energy management system issues an energy-saving instruction to the intelligent control system.

[0016] Specifically, the S1 step is specifically as follows:

[0017] When the vehicle enters the automatic code scanning system, the code scanning process is started. The industrial control computer collects images through the industrial camera. After the recognition software analyzes the barcode information, the data is uploaded to the intelligent control system in real time.

[0018] Specifically, in the step S2, the coordinate instruction is to drive the automatic reverse pushing device through real-time communication and output the vehicle to the external conveyor line.

[0019] Further, the specific steps of driving the automatic reverse pushing device are as follows:

[0020] The automatic reverse pushing device rises to the height of the bin outlet. The two-way push rod mechanism extends into the bin to push the vehicle out in the reverse direction to the lifting platform. After the lifting platform descends to the height of the conveyor line, the vehicle is transported out through the conveyor line.

[0021] Specifically, in the step S2, the distribution instruction is to trigger the intelligent incoming material distribution device. After receiving the in-place signal, in combination with the storage strategy, coordinate the automatic bin shifting device and feedback the bin position back to the intelligent warehouse management system.

[0022] Further, the specific steps of triggering the intelligent incoming material distribution device are as follows:

[0023] The distribution instruction adjusts the height of the intelligent incoming material distribution device through the lifting mechanism to align with the inlet of the target bin. After the pneumatic blocking device positions the vehicle to the starting position of the push rod, the electric forward pushing mechanism pushes the vehicle into the bin with a preset force.

[0024] Further, the storage strategy is specifically: based on inventory data, order requirements, and the capabilities of the shifting device, formulate a dynamic storage plan.

[0025] Further, the specific steps of coordinating the automatic bin shifting device are as follows:

[0026] When a certain bin is full, the automatic bin shifting device moves the bin rack according to the instruction and switches the empty bin to the docking position of the distribution device.

[0027] Further, in the step S4, the energy-saving instruction is specifically:

[0028] The system automatically switches to the energy-saving mode during idle periods to reduce standby energy consumption, analyzes historical data, generates an energy consumption peak and valley report, and recommends the optimal equipment start and stop times.

[0029] In the above technical solution, the present invention is improved in the following way:

[0030] 1. Multi-module collaborative innovation: Through intelligent algorithms (path planning optimized by genetic algorithms), the scanning, allocation, shifting, and reverse pushing modules are deeply integrated to achieve the full-automatic transfer of the vehicle from warehousing to outbound.

[0031] 2. Linkage between scanning and allocation: After the automatic scanning system identifies the vehicle, the allocation device dynamically adjusts the pushing order based on the priority algorithm (such as the urgency of the work order).

[0032] 3. Collaboration between shifting and reverse pushing: When the storage bin is full, the shifting device switches to an empty bin, and at the same time, the reverse pushing device synchronously releases the target vehicle.

[0033] 4. Intelligent error prevention mechanism: Multi-sensor redundant verification (pressure / photoelectric / vision) is adopted, and abnormal signals between modules are shared in real time.

[0034] 5. The "dynamic storage bin expansion" technology is pioneered, and the capacity limit of the traditional fixed storage bin is broken through by the shifting device.

[0035] The advantages of the present invention are as follows:

[0036] 1. The barcode recognition rate is improved through multi-angle industrial cameras + deep learning algorithms. Combined with the real-time collaboration of PLC and distributed I / O modules, manual operation errors are eliminated, and unmanned operation of the entire process of scanning, allocation, storage, and reverse pushing is achieved.

[0037] 2. The modular storage bin rack with servo-driven ball screw is adopted, which supports horizontal / vertical expansion, increases the storage density; based on the heat analysis algorithm, the high-frequency vehicles are automatically scheduled to the proximal storage positions, improving the space utilization rate and shortening the material taking time.

[0038] 3. The digital twin of the vehicle is generated through three-dimensional coordinate binding and updated by integrating the time-series database. It is compatible with the MES / ERP system interface and provides the full-process traceability ability from warehousing to scrapping.

[0039] 4. The dynamic voltage regulator controller adjusts the motor voltage according to the load, combined with the energy-saving mode during idle periods, reducing energy consumption; the energy management module extends the life of key components and reduces the maintenance cost.

[0040] 5. The three-redundancy sensor verification mechanism of pressure / photoelectric / vision is adopted, and abnormal signals are shared across modules in real time. Combined with the adaptive image distortion correction algorithm, it still operates stably in complex scenarios such as barcode blurring, tilting, and occlusion.

[0041] 6. The data of the entire process from warehousing to outbound can be traced, compatible with the MES / ERP system interface, and the vehicle life cycle report is automatically generated. When each vehicle enters the warehouse, three-dimensional coordinates (X / Y / Z axis positions) are generated, associated with the storage bin number and layer number, supporting fuzzy query and real-time positioning.

[0042] 7. Display the status of the silo (fully loaded / empty / anomaly) through 3D modeling, and count key indicators such as storage efficiency and turnover rate.

[0043] 8. When the silo capacity reaches the threshold or the vehicle stays for overtime, the system automatically triggers an alarm and pushes it to the production management terminal. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Embodiment

[0060] As Figure 2 shown, the present invention discloses an intelligent storage management system for SMT production line carriers, including an automatic code scanning system, an intelligent incoming material distribution device, an automatic bin shifting device, an automatic reverse pushing device, an intelligent control system, an intelligent warehouse management system, and an intelligent energy management module;

[0061] Specifically, the automatic code scanning system includes an industrial computer, an industrial camera, and recognition software. The industrial computer collects images through the industrial camera, and the recognition software analyzes the image information;

[0062] Furthermore, the industrial computer, serving as the core control unit, is equipped with a high-speed data processing module for real-time communication with the intelligent warehouse management system. Multi-angle industrial cameras, utilizing high-resolution CMOS sensors, are installed above and on both sides of the conveyor line entrance, enabling 360° scanning of barcodes on the surface of the carrier. Adaptive recognition software, incorporating deep learning algorithms, can identify blurred, tilted, or partially obscured barcodes and automatically correct image distortion.

[0063] In one feasible implementation, when a vehicle enters the system, a photoelectric sensor triggers the barcode scanning process. The industrial computer captures the image using a camera, and recognition software interprets the barcode information. It then binds the vehicle ID to the unique smart warehouse code, and the data is uploaded to the smart warehouse management system in real time. If the barcode scan fails, the system automatically triggers an alarm and pauses the conveyor line, prompting manual intervention through the human-machine interface to prevent erroneous data from entering subsequent processes.

[0064] Specifically, if Figure 3 As shown, the intelligent incoming material distribution device includes a modular conveying device, a pneumatic blocking device, a lifting mechanism, and an electric forward pushing mechanism.

[0065] Furthermore, the modular conveying device utilizes a segmented belt conveyor line, each segment driven independently, allowing for dynamic speed adjustment. A pneumatic blocking device uses a cylinder to drive a baffle, which, in conjunction with a photoelectric sensor, precisely positions the carrier to the stop position. The lifting mechanism utilizes a servo motor to drive the Z-axis lifting platform, which, in conjunction with guide rails, achieves longitudinal displacement, ensuring the dispensing device adapts to silos of varying heights. The electric forward push mechanism integrates high-precision linear guides and stepper motors, with a pressure sensor at the end of the push rod to prevent damage to the carrier caused by excessive pushing.

[0066] In one feasible implementation, after a code is scanned, a carrier enters the dispensing device. Following instructions from the intelligent warehouse management system, the system uses a lifting mechanism to adjust the height of the dispensing device to align it with the target silo entrance. After a blocking mechanism positions the carrier at the push rod's starting position, a forward push mechanism pushes the carrier smoothly into the silo with a preset force. A pressure sensor provides real-time feedback to ensure collision-free insertion.

[0067] Specifically, if Figure 4 As shown, the automatic silo shifting device includes a silo frame and a bidirectional shifting drive mechanism, and the bidirectional shifting drive mechanism is arranged below the silo frame.

[0068] Specifically, the multi-layer expandable silo rack adopts a modular design, with independent slide rails on each layer, allowing for horizontal expansion to eight silos. A bidirectional shift drive mechanism, driven by a servo motor and a ball screw, enables precise movement of the silo rack in the X-axis direction.

[0069] In an implementable embodiment, when a certain bin is full, the shifting device moves the bin rack according to the system instruction, switches the empty bin to the docking position of the distribution device, and realizes seamless connection. The servo-driven horizontal expansion drives the bin rack to move horizontally through a servo motor + ball screw, with a single expansion step accuracy of ±0.1 mm, supports dynamic switching of 8 positions, and the storage density is increased to 4 times that of the traditional fixed bin. The modular splicing design supports horizontal / vertical expansion of the bin rack (maximum support for 32 positions). The intelligent bin position optimization strategy automatically matches the bin positions according to the size (length / width / height) of the carrier, improving the space utilization rate. Using the heat analysis algorithm, the frequently used carriers are preferentially allocated to the proximal bins, reducing the average material taking time.

[0070] Specifically, as Figure 5 shown, the automatic reverse pushing device includes a lifting platform and a bidirectional push rod mechanism, and the lifting platform is connected to the bidirectional push rod mechanism. The lifting platform is driven by a motor and is equipped with a displacement sensor, supporting the height adaptation of the carrier from the bin to the conveyor line. The bidirectional push rod mechanism is driven by two motors, and infrared obstacle avoidance sensors are integrated at the ends of the push rods to prevent interference with the carrier during the reverse pushing process.

[0071] In an implementable embodiment, when it is necessary to call the carrier in the bin, the reverse pushing device rises to the height of the bin outlet, the push rod extends into the bin to push the carrier out in the reverse direction to the lifting platform, and after the platform descends to the height of the conveyor line, the carrier is transported out through the conveyor line.

[0072] Specifically, as Figure 6 shown, the intelligent control system includes a main control PLC and a distributed I / O module. The main control PLC is configured to coordinate the action timing of each hardware module, and the distributed I / O module is configured to be connected to sensors and actuators through industrial Ethernet;

[0073] In an implementable embodiment, the intelligent control system dynamically allocates the storage positions of the carriers based on the principles of priority and shortest path, and real-time monitors the device status (such as motor overload, sensor failure), triggers an alarm and generates a fault log.

[0074] Specifically, as Figure 7 shown, the intelligent warehouse management system is configured to establish a digital twin of the carrier and realize three-dimensional coordinate binding. The main innovation points of the intelligent warehouse management system are dynamic binding and data mapping; combining the carrier barcode and visual positioning to generate a unique digital twin, and real-time binding the three-dimensional coordinates (X / Y / Z accuracy) with the physical position of the bin; using a time-series database to store the state changes of the carrier, supporting millisecond-level updates; using a relational database to map the logical relationship of the bin, realizing the triple association of "bin-carrier-work order"; supporting fault-tolerant retrieval (such as partial barcode missing, spelling error), and the query hit rate is increased to 99.8%.

[0075] Furthermore, the innovative advantages of the intelligent warehouse management system are mainly:

[0076] 1. Full-link tracking: Data from entry to exit is traceable, compatible with MES / ERP system interfaces, and automatically generates vehicle lifecycle reports. Three-dimensional coordinates (X / Y / Z axis position) are generated for each vehicle upon entry, associated with the silo number and level, supporting fuzzy queries and real-time positioning.

[0077] 2. Visual monitoring interface: Displays the silo status (full / empty / abnormal) through 3D modeling, and counts key indicators such as storage efficiency and turnover rate.

[0078] 3. Intelligent early warning mechanism: When the silo capacity reaches the threshold or the vehicle is detained for a period of time, the system automatically triggers an early warning and pushes it to the production management terminal.

[0079] Specifically, the intelligent energy management module includes an energy consumption monitoring terminal and a dynamic voltage regulation controller. The energy consumption monitoring terminal is installed in the power supply lines of each motor and pneumatic component to collect real-time power consumption data. The dynamic voltage regulation controller automatically adjusts the motor drive voltage based on load demand to achieve energy-saving operation.

[0080] Furthermore, if Figure 8 As shown, the system automatically switches to "Energy Saving Mode" during idle periods (such as low-load night shifts), reducing conveyor roller speed and lighting brightness, thereby reducing standby energy consumption. By analyzing historical data, it generates energy consumption peak and valley reports and recommends optimal equipment start and stop times, thereby reducing the factory's overall electricity costs.

[0081] Furthermore, the main advantages of the intelligent energy management module are:

[0082] 1. Save 20%-30% energy compared to traditional systems and meet green manufacturing standards.

[0083] 2. Through intelligent algorithms (genetic algorithm optimized path planning), the scanning, allocation, shifting, and reverse inference modules are deeply integrated to achieve fully automatic flow of vehicles from warehousing to outbound delivery.

[0084] 3. After the automatic scanning system identifies the carrier, the allocation device dynamically adjusts the push order based on the priority algorithm (such as the urgency of the work order).

[0085] 4. When the silo is full, the shift device switches to an empty silo, and the reverse thrust device releases the target carrier synchronously.

[0086] 5. Multi-sensor redundancy verification (pressure / photoelectric / vision) is adopted, and abnormal signals between modules are shared in real time.

[0087] 6. The first "dynamic silo expansion" technology breaks through the capacity limitations of traditional fixed silos through a shifting device.

[0088] 7. The storage efficiency of the vehicle is increased by 80% compared with manual operation, and the error rate is reduced to less than 0.1%.

[0089] 8. The modular design supports increasing or decreasing the number of bins according to the production line requirements, adapting to factories of different scales.

[0090] 9. The system provides a remote diagnosis interface, and software can be updated and troubleshooting can be performed through the cloud, reducing downtime.

[0091] 10. The energy management module extends the lifespan of key components of the equipment (such as motors and cylinders) by 15% - 20%, reducing the factory maintenance cost.

[0092] In an implementable embodiment, as Figure 1 shown, the steps are as follows:

[0093] S1. The vehicle enters the automatic barcode scanning system, and the automatic barcode scanning system obtains data and uploads the data to the intelligent control system;

[0097] In an implementable embodiment, the specific content of step S1 is:

[0098] When the vehicle enters the automatic barcode scanning system, the barcode scanning process is started. The industrial control computer collects images through an industrial camera. After the barcode information is parsed by the recognition software, the data is uploaded to the intelligent control system in real time.

[0099] Specifically, in step S2, the coordinate instruction is to drive the automatic reverse pushing device through real-time communication to output the vehicle to the external conveyor line.

[0100] In an implementable embodiment, the specific steps of driving the automatic reverse pushing device are:

[0101] The automatic reverse pushing device rises to the height of the bin outlet, the two-way push rod mechanism extends into the bin to push the vehicle out in the reverse direction to the lifting platform. After the lifting platform descends to the height of the conveyor line, the vehicle is transported out through the conveyor line.

[0102] In an implementable embodiment, in step S2, the distribution instruction is to trigger the intelligent incoming material distribution device. After receiving the in-place signal, the intelligent incoming material distribution device coordinates the automatic bin shifting device in combination with the storage strategy and feeds back the bin position to the intelligent warehouse management system.

[0103] In an implementable embodiment, the specific steps of triggering the intelligent incoming material distribution device are:

[0104] The dispensing instruction adjusts the height of the intelligent incoming material dispensing device through the lifting mechanism to align it with the entrance of the target bin. After the pneumatic blocking device positions the carrier to the starting position of the push rod, the electric forward pushing mechanism pushes the carrier into the bin with a preset force.

[0105] In an implementable embodiment, the storage strategy is specifically: based on inventory data, order requirements, and the capabilities of the shifting device, a dynamic storage plan is formulated.

[0106] In an implementable embodiment, the specific steps for coordinating the automatic bin shifting device are as follows:

[0107] When a certain bin is full, the automatic bin shifting device moves the bin rack according to the instruction to switch the empty bin to the docking position of the dispensing device.

[0108] In an implementable embodiment, the energy-saving instruction is specifically:

[0109] The system automatically switches to the energy-saving mode during idle periods to reduce standby energy consumption, analyzes historical data, generates an energy consumption peak-valley report, and recommends the optimal equipment start-stop time.

[0110] The advantages of the present invention are specifically as follows:

[0111] 1. By using a multi-angle industrial camera + deep learning algorithm to improve the barcode recognition rate, combined with the real-time collaboration of the PLC and the distributed I / O module, manual operation errors are eliminated, and unmanned operation is achieved throughout the entire process of barcode scanning, dispensing, storage, and reverse pushing.

[0112] 2. The modular bin rack with servo-driven ball screws supports horizontal / longitudinal expansion, increasing the storage density; based on the heat analysis algorithm, high-frequency carriers are automatically scheduled to the proximal bins, improving the space utilization rate and shortening the material retrieval time.

[0113] 3. By generating a digital twin of the carrier through three-dimensional coordinate binding, and realizing updates by integrating the time-series database, it is compatible with the MES / ERP system interface, providing the ability to trace the entire process from warehousing to scrapping.

[0114] 4. The dynamic voltage regulator controller adjusts the motor voltage according to the load, combined with the energy-saving mode during idle periods, to reduce energy consumption; the energy management module extends the lifespan of key components and reduces maintenance costs.

[0115] 5. Adopting a three-redundancy sensor calibration mechanism of pressure / photoelectric / vision, abnormal signals are shared in real time across modules, and combined with the adaptive image distortion correction algorithm, it can still operate stably in complex scenarios such as barcode blurring, tilting, and occlusion.
