Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of product material warehousing management, and particularly relates to a veneer panel warehousing detection device and a veneer panel warehousing method. BACKGROUND

[0002] With the rapid development of the industry, the change of the times and the environment, in order to reduce cost and increase efficiency, gradually develop towards intelligence. After the production of traditional artificial veneer panels, the detection speed of some detection devices cannot keep up with the production and warehousing speed of the veneer panels, resulting in that the detection link becomes the bottleneck of the production process. For example, traditional manual detection or detection equipment based on a single sensor, when facing a large number of veneer panel warehousing detection, the efficiency is low, which cannot meet the demand of rapid turnover, and the automation degree of part of the equipment is not high, and there are many manual intervention links, such as sample placement, data recording and analysis. This not only increases the labor cost, but also easily leads to inaccurate detection results due to human factors. SUMMARY

[0003] Therefore, the present application provides a veneer panel warehousing detection device and a veneer panel warehousing method, which solves the problem of how to accurately detect the veneer panel material warehousing process and automatically warehouse.

[0004] In a first aspect, the present application provides a veneer panel warehousing detection device, comprising: a transportation corridor detection device, a warehousing corridor detection device and a PLC controller, wherein:

[0005] The transportation corridor detection device comprises a plurality of node detection units, each node detection unit is arranged on a transportation unit of the transportation corridor, and is used for detecting the state of the veneer panel material located on the transportation corridor and the relative position on the transportation corridor, and sending the detection result to the PLC controller;

[0006] The warehousing corridor detection device is arranged on the warehousing corridor, and is used for detecting the state of the veneer panel material located on the warehousing corridor, the relative position on the warehousing corridor, the size information of the material, and sending the detection result to the PLC controller;

[0007] The PLC controller is used for forwarding the detection results generated by the transportation corridor detection device and the warehousing corridor detection device to the equipment management system WCS for controlling the running state of the transportation corridor and the warehousing corridor.

[0008] The surface panel warehouse-in detection device provided by the embodiment of the application can accurately detect the state and position of the material during transportation and warehousing, which helps to ensure the quality of the surface panel. The quality problems caused by improper transportation are reduced by monitoring from the transportation link, and further inspection is performed in the warehousing link to ensure that only qualified materials can be smoothly warehoused, thereby improving the overall quality of the product. The PLC controller plays a key role in data conversion, and the detection results of the transportation corridor detection device and the warehouse-in corridor detection device are forwarded to the equipment management system WCS, so that the WCS can obtain the detailed information of the material in real time. This data sharing mechanism is beneficial to the collaborative work of the entire system, and the equipment management system WCS can accurately control the running state of the transportation corridor and the warehouse-in corridor according to the information.

[0009] In an optional embodiment, each node detection unit of the transportation corridor detection device is provided with the same sensor, including:

[0010] The first state detection sensor is arranged at a preset position close to the transportation unit at the entrance end of the transportation corridor, and is used to detect whether there is a surface panel material on the transportation corridor, and generate material state detection information;

[0011] The first deceleration trigger sensor is arranged at a first preset position close to the end of the transportation unit in the transportation direction, and is used to detect whether the surface panel material reaches the first preset distance before the end of the transportation unit;

[0012] The first arrival detection sensor is arranged at a second preset position close to the end of the transportation unit in the transportation direction, and is used to detect whether the surface panel material reaches the second preset distance before the end of the transportation unit, and the second preset distance is less than the first preset distance;

[0013] The first out-of-position detection sensor is arranged at the last end of the transportation unit in the transportation direction of the transportation corridor, and is used to detect whether the surface panel material on the transportation device exceeds the last end of the transportation unit.

[0014] Through the cooperative work of the above sensors, the embodiment of the application can make the transportation process of the surface panel material in the transportation corridor more efficient. Precise deceleration and arrival control can reduce the pause and adjustment time in the transportation process, so that the material can smoothly reach the transportation end at a more reasonable speed and position, thereby improving the efficiency of the entire transportation process. The arrangement of the sensor can effectively prevent accidents of the material during transportation, and improve the safety of the transportation link.

[0015] In an optional embodiment, the warehouse-in corridor detection device includes:

[0016] The second state detection sensor is arranged at a preset position close to the entrance end of the warehouse-in corridor, and is used to detect whether there is a surface panel material on the warehouse-in corridor, and generate material state detection information;

[0017] A second deceleration trigger sensor is arranged at a third preset position before the end of the storage corridor in the transportation direction, and is used to detect whether the decorative panel material reaches a third preset distance before the end of the storage corridor.

[0018] A second in-position detection sensor is arranged at a fourth preset position before the end of the storage corridor in the transportation direction, and is used to detect whether the decorative panel material reaches a fourth preset distance before the end of the storage corridor, wherein the fourth preset distance is smaller than the third preset distance.

[0019] A second out-of-position detection sensor is arranged at the end of the storage corridor in the transportation direction, and is used to detect whether the decorative panel material exceeds the end of the storage corridor.

[0020] A length detection sensor is arranged at the bottom end of the storage corridor, and is used to detect the length of the decorative panel material.

[0021] Front and rear boundary detection sensors are arranged at preset positions on the front and rear sides of the storage corridor, and are used to detect whether the decorative panel material is inclined out of the transportation direction during transportation.

[0022] Left and right boundary detection sensors are arranged at preset positions on the two sides of the storage corridor, and are used to detect whether the decorative panel material is inclined out of the direction perpendicular to the transportation direction during transportation.

[0023] A height sensor is arranged at the end of the storage corridor, and is used to detect the height information of the decorative panel material.

[0024] The storage corridor detection device can accurately monitor the state of the material and accurately control the transportation speed of the material, and the boundary detection sensors can timely detect the inclination of the material in the transportation direction and the direction perpendicular to the transportation direction, which helps to find the quality problems that may cause damage to the material or inconvenience in storage in advance, and ensures that the decorative panel material enters the storage link in a good state.

[0025] In an optional embodiment, the distance between the length detection sensor and the second in-position detection sensor is determined according to the length of the material of different specifications.

[0026] Since the lengths of decorative panel materials of different specifications are different, the distance between the length detection sensor and the second in-position detection sensor is determined according to the length, which can ensure that the length detection sensor detects the length of the material at the appropriate time, avoid early or late detection due to unreasonable distance setting, ensure the accuracy of the detection data, and determine which specification of material according to the position of the sensor and the detection result of the sensor.

[0027] In an alternative embodiment, the first state detection sensor, the first deceleration trigger sensor, the first to-position detection sensor, the first off-position detection sensor, the second state detection sensor, the second deceleration trigger sensor, the second to-position detection sensor, the second off-position detection sensor, and the length detection sensor are all diffuse reflection photoelectric sensors.

[0028] As a non-contact sensor, the diffuse reflection photoelectric sensor does not come into physical contact with the surface of the material when detecting various states and sizes of the material, which is crucial for the surface quality of the decorative panel. This avoids physical damage such as scratches and collisions caused by contact detection, ensuring that the appearance quality of the material is not affected, especially for decorative panels with high surface quality requirements. In addition, in the industrial environment of transportation and warehousing, there may be complex factors such as dust and light changes. The diffuse reflection photoelectric sensor can adapt to these environmental changes to a certain extent, as long as the reflection intensity of the light signal is within its detectable range, it can work normally. Compared with some sensors with strict environmental requirements, it has better robustness, reduces detection errors or failures caused by environmental factors, and ensures the continuity of detection work.

[0029] In an alternative embodiment, the front and rear boundary detection sensors and the left and right boundary detection sensors are all mirror reflection photoelectric sensors.

[0030] The mirror reflection photoelectric sensor has high detection accuracy for boundaries. For the front and rear boundary detection sensors, it can accurately determine whether the decorative panel material exceeds the preset boundary range in the transportation direction. For the left and right boundary detection sensors, it can also accurately detect whether the material is tilted beyond the boundary in the direction perpendicular to the transportation direction. This high-precision detection helps to detect small positional deviations of the decorative panel during transportation in a timely manner, ensuring that the material is always on the correct transportation track, which is crucial for ensuring the quality of the material and smooth warehousing.

[0031] In an alternative embodiment, the PLC controller is configured to forward the detection results generated by the transportation corridor detection device and the warehousing corridor detection device to the equipment management system WCS to monitor the running state of the transportation corridor and the warehousing corridor, including:

[0032] When the PLC controller detects that the sensing light source of the first state detection sensor or the second state detection sensor receives changes or abnormalities, it forwards the information to the equipment management system WCS to control the corresponding corridor motor to start running.

[0033] The PLC controller monitors the first state detection sensor and the second state detection sensor to sense the change or abnormality of the light source received, and when the first deceleration trigger sensor and the second deceleration trigger sensor sense the change or abnormality of the light source, the PLC controller forwards to the equipment management system WCS to control the corresponding corridor motor to run at a reduced speed.

[0034] The PLC controller monitors the first state detection sensor and the second state detection sensor to sense the change or abnormality of the light source received, and when the first to-position detection sensor and the second to-position detection sensor sense the change or abnormality of the light source received, the PLC controller forwards to the equipment management system WCS to control the corresponding corridor motor to stop running.

[0035] The PLC controller monitors the first state detection sensor and the second state detection sensor to sense the change or abnormality of the light source received, and when the first to-position detection sensor and the second to-position detection sensor sense the change or abnormality of the light source received, the PLC controller forwards to the equipment management system WCS to control the corresponding corridor motor to stop running.

[0036] The PLC controller monitors the left and right boundary detection sensors and the front and rear boundary detection sensors to sense the blocking of any light source, and forwards to the equipment management system WCS to control the in-warehouse corridor motor to stop running and send an alarm signal.

[0037] The PLC controller in the embodiment of the application serves as a bridge between the transportation corridor detection device, the in-warehouse corridor detection device and the equipment management system WCS, integrates and forwards the detection results of each sensor, and in this way of centralized data processing and transmission, the equipment management system WCS can comprehensively and in real time understand the state of the material in the transportation and in-warehouse process, thereby realizing effective management and control of the entire logistics system, promoting the collaborative work between different equipment and systems, improving the overall coordination and stability of the system, making the entire system adapt to various specifications of material transportation and in-warehouse scenes, and improving the adaptability and intelligent level.

[0038] In an optional implementation, the device further comprises a sensing device and a code scanning device, wherein:

[0039] The sensing device is arranged at the in-warehouse port and is used to sense whether the decorative panel material reaches the in-warehouse port.

[0040] The code scanning device is used to scan and read the product barcode information of the decorative panel material at the in-warehouse port.

[0041] The embodiment of the present application can accurately judge whether the facing plate material reaches the warehouse inlet through the induction device. Based on the induction, the subsequent code scanning device and other warehouse inlet operations can be automatically triggered, so that the entire warehouse inlet process can be orderly unfolded according to the material arrival condition, avoiding the inaccuracy and delay of manual judgment of the material position, greatly improving the automation degree of the warehouse inlet process, enabling the material to enter the warehouse more quickly, and improving the overall warehouse inlet efficiency.

[0042] In a second aspect, the present application provides a facing plate warehouse detection method, comprising:

[0043] The production execution system MES generates a facing plate material and a corresponding product barcode, and triggers a product transportation signal based on a consistent confirmation signal of the facing plate material and the corresponding product barcode;

[0044] The transportation corridor of the facing plate warehouse detection device of the first aspect starts to transport the facing plate material based on the product transportation signal, and detects the facing plate material based on the transportation corridor detection device;

[0045] The equipment management system WCS starts the imaging code scanning device to read the product barcode information after the induction device senses that the product barcode information is read to the warehouse inlet, and starts the warehouse detection device of the facing plate warehouse detection device of the first aspect to detect the facing plate material when the product barcode information is consistent with the finished product data provided by the production execution system MES. After the detection is passed, the corresponding three-dimensional warehouse location is allocated based on the read product barcode information, and the barcode information is fed back to the warehouse management system WMS after the warehouse operation is completed. The warehouse management system WMS stores the inventory information based on the barcode information, and sends the inventory information to the production execution system MES.

[0046] The facing plate warehouse detection method provided by the embodiment of the present application records and associates multiple links around the product barcode information in the whole process. Whether it is related data in the production link, detection condition in the transportation process, or inventory information after the warehouse, etc., can be traced back through the barcode information. Once the product has quality problems, each link can be quickly traced back to accurately locate the problem, which helps to improve the product quality control level and the ability of the enterprise to deal with quality problems.

[0051] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0052] In the embodiments of the present application, a veneer panel warehouse entry detection device is provided, as shown in Figure 1 which comprises a transportation corridor detection device, a warehouse entry corridor detection device and a PLC controller, as shown in Figure 2 which is a schematic diagram of the application scenario thereof. The transportation corridor detection device is arranged on a transportation corridor, and the warehouse entry corridor detection device is arranged on a warehouse entry corridor, for detecting the state of the veneer panel material in the transportation process after the production line of the veneer panel material generates finished products. Specifically,

[0053] The transportation corridor detection device comprises a plurality of node detection units, each of which is arranged on a transportation unit of the transportation corridor, for detecting the state of the veneer panel material on the transportation corridor and the relative position on the transportation corridor, and sending the detection results to the PLC controller.

[0054] The warehouse entry corridor detection device is arranged on the warehouse entry corridor, for detecting the state of the veneer panel material on the warehouse entry corridor, the relative position on the warehouse entry corridor, the size information of the material, and sending the detection results to the PLC controller.

[0055] The PLC controller is used for the PLC controller, for sending the detection results generated by the transportation corridor detection device and the warehouse entry corridor detection device, and forwarding the detection results to the device management system WCS for controlling the running state of the transportation corridor and the warehouse entry corridor.

[0056] The transport corridor detection device provided by the embodiment of the present application can detect the state of the veneer panel material on the transport corridor. The warehouse entry corridor detection device can not only detect the material state, but also obtain size information and barcode information of the material. Through the cooperation of the detection devices of different corridors, the multi-dimensional state and key attributes of the veneer panel from the transportation to the warehouse entry process are comprehensively detected, which helps to accurately grasp the material situation and avoid management errors caused by information loss and other problems.

[0057] The PLC controller acts as a transit hub and can forward various detection results generated by the transport corridor detection device and the warehouse entry corridor detection device to the equipment management system WCS to control the running state of the transport corridor and the warehouse entry corridor. Once an abnormal situation of the material is detected at a certain link (such as poor material state, size inconsistency, etc.), appropriate measures can be taken through the PLC controller and the equipment management system for adjustment or processing in a timely manner to avoid the problem material entering the subsequent storage link and ensure the high-quality operation of the entire warehouse entry process, thereby realizing seamless connection and collaborative work of the detection link and the overall equipment management system, which is beneficial to creating an automatic and intelligent veneer panel warehouse entry management process, reducing the uncertainty and errors caused by manual intervention, and improving the warehouse entry efficiency and accuracy.

[0058] The transport corridor in the embodiment of the present application is spliced by multiple transport units. The length of each transport unit is determined according to the length of the veneer panel material and is slightly longer than the length of the finished product, for example, the finished product length is 2 meters, and the transport unit is 2.2 meters. A node detection unit is arranged on each transport unit to detect the state of the veneer panel material and the relative position on the transport corridor. Each node detection unit of the transport corridor detection device is provided with the same sensor.

[0059] In an embodiment, the sensors of the node detection unit are all diffuse reflection photoelectric sensors, which integrate a transmitter and a receiver. The transmitter emits a light beam. When the light beam irradiates the surface of an object, part of the light beam is diffusely reflected back to the receiver. If the object blocks part of the light beam, the sensor can receive the change of the reflected light beam to determine the position, shape, color or motion state of the object.

[0060] In the embodiment of the present application, the state of the photoelectric sensor of the node detection unit is as follows: N represents no material; 0 represents material; 1 represents running; 2 represents stopping; 3 represents warehouse entry; 4 represents normal; and 5 represents abnormal. The veneer panel material has two specifications, and the length and width parameters are: length 2440* width 1220, length 2800* width 1220, unit: centimeter. As shown in FIG. 8, the sensor of each node detection unit includes: Figure 3

[0061] ​The first state detection sensor is arranged at a preset position close to the input end of the conveying unit, and is used for detecting whether there is a decorative panel material on the conveying channel, and generating material state detection information; for example, the sensor is installed at a position 60 cm away from the input end of the conveying channel, the sensing light source normally receives, the state is no material (N), the channel state is (2); the sensing light source receives changes or abnormities, the state is material (0), the channel state is (1), at this time, the PLC controller transmits to the equipment management system WCS to control the motor of the conveying channel to start running.

[0064] The first out-of-position detection sensor is arranged at the last end of the conveying unit in the conveying direction of the conveying channel, and is used for detecting whether the decorative panel material on the conveying device exceeds the last end of the conveying unit; the first out-of-position detection sensor functions as a protection switch, is installed at the last end of the channel, the right light source is directed to the left, the sensing light source receives changes or abnormities, the state is material (0), the channel state is (2), the PLC controller transmits to the equipment management system WCS to control the motor of the conveying channel to stop running and alarm.

[0065] The sensors in the warehouse entry channel detection device in the embodiment of the application are all photoelectric sensors, and the detection states are as follows: N represents no material; 0 represents material; 1 represents running; 2 represents stopping; 3 represents that the warehouse can be entered; 4 represents normal; and 5 represents abnormal. Figure 3 As shown in the figure, the warehouse entry channel detection device comprises:

[0066] The second state detection sensor is arranged at a preset position close to the loading entrance end of the loading gallery, and is used for detecting whether there is a decorative panel material on the loading gallery, and generating material state detection information; for example, it is installed at a position 60 cm away from the loading entrance end of the loading gallery, the sensing light source normally receives, the state is no material (N), and the gallery state is (2); the sensing light source receives changes or abnormities, the state is material (0), the gallery state is (1), and at this time, the PLC controller forwards to the equipment management system WCS to control the loading gallery motor to start running.

[0067] The second deceleration trigger sensor is arranged at a third preset position close to the end of the transportation direction of the loading gallery, and is used for detecting whether the decorative panel material reaches the third preset distance before the end of the loading gallery; the second deceleration trigger sensor functions as a deceleration trigger switch, is installed at a position 40 cm before the end of the loading gallery, the right light source is directed to the left, the sensing light source receives changes or abnormities, the state is material (0), the gallery state is (1), and the PLC controller forwards to the equipment management system WCS to control the loading gallery motor to run at a reduced speed.

[0068] The second to-position detection sensor is arranged at a fourth preset position close to the end of the transportation direction of the loading gallery, and is used for detecting whether the decorative panel material reaches the fourth preset distance before the end of the loading gallery, and the fourth preset distance is less than the third preset distance; the second to-position detection sensor functions as a stop trigger switch, is installed at a position 10 cm before the end of the loading gallery, the right light source is directed to the left, the sensing light source receives changes or abnormities, the state is material (0), the gallery state is (2), and the PLC controller forwards to the equipment management system WCS to control the loading gallery motor to stop running.

[0069] The second out-of-position detection sensor is arranged at the end of the transportation direction of the loading gallery, and is used for detecting whether the decorative panel material exceeds the end of the loading gallery; the second out-of-position detection sensor functions as a protection switch, is installed at the end of the loading gallery, the right light source is directed to the left, the sensing light source receives changes or abnormities, the state is material (0), the gallery state is (2), and the PLC controller forwards to the equipment management system WCS to control the loading gallery motor to stop running and alarm.

[0070] The length detection sensor is arranged at the bottom end of the loading gallery, and is used for detecting the length of the decorative panel material; the light source is directed upward, and the distance between the light source and the second to-position detection sensor is 2750 cm, the sensing light source normally receives, the material specification is long 2440*wide 1220, the sensing light source receives changes or abnormities, and the length specification is long 2800*wide 1220.

[0071] Front and rear boundary detection sensors are arranged at preset positions on the front and rear sides of the warehouse entry corridor and are used to detect whether the decorative panel material is tilted out of the transport direction during transport. For example, a mirror reflective photoelectric sensor is installed on the top edge of the left and right sides of the front and rear sides of the corridor and senses downward, and a mirror is installed below. If the sensing light source is normal, the corridor state is changed (4), and if the sensing light source is blocked, the corridor state is changed (5), and the PLC controller transmits to the equipment management system WCS to control the warehouse entry corridor motor to stop running and alarm.

[0072] Left and right boundary detection sensors are arranged at preset positions on both sides of the warehouse entry corridor and are used to detect whether the decorative panel material is tilted out of the direction perpendicular to the transport direction during transport. For example, a mirror reflective photoelectric sensor is installed on the top edge of the left and right sides of the corridor and senses downward, and a mirror is installed below. If the sensing light source is normal, the corridor state is changed (4), and if the sensing light source is blocked, the corridor state is changed (5), and the PLC controller transmits to the equipment management system WCS to control the warehouse entry corridor motor to stop running and alarm.

[0073] Height sensors are arranged at the end of the warehouse entry corridor and are used to detect the height information of the decorative panel material. For example, they are installed on the left and right sides of the end of the warehouse entry corridor and start height detection upon receiving the detection instruction from the WSC. The measurement device calculates the blocked height, and the calculated height is further reduced by the height of the material cushion cover (the cushion cover is uniformly 18 mm per sheet). The WCS obtains the data and matches the height error with the number identified by the code reader. If the error does not exceed 2 cm, otherwise, an error is reported, the corridor state is changed (5), an alarm is recorded, and the operation is stopped.

[0074] In an embodiment, the second state detection sensor, the second deceleration trigger sensor, the second to-position detection sensor, the second out-of-position detection sensor, and the length detection sensor are all diffuse reflection photoelectric sensors, which integrate a transmitter and a receiver. The transmitter emits a light beam, and when the light rays strike the surface of an object, part of the light rays will be diffusely reflected back to the receiver. If the object blocks part of the light rays, the sensor can receive the change in reflected light, thereby judging the position, shape, color, or motion state of the object. As a non-contact sensor, the diffuse reflection photoelectric sensor does not come into physical contact with the surface of the material when detecting various states and sizes of the veneer material. This is crucial for veneer products with high surface quality requirements, as it avoids physical damage such as scratching and collision that may occur during contact detection, ensuring that the appearance quality of the material is not affected. This is particularly important for veneer with high decorative requirements, as it effectively maintains the integrity of the material. In addition, in the industrial environment of transportation and warehousing, there may be complex factors such as dust and light changes. The diffuse reflection photoelectric sensor can adapt to these environmental changes to some extent, as long as the reflection intensity of the light signal is within its detectable range, it can work normally, has better robustness, reduces detection errors or failures caused by environmental factors, and ensures the continuity of the detection work.

[0075] The front and rear boundary detection sensors and the left and right boundary detection sensors are all mirror reflection photoelectric sensors, which consist of a light emitter and a light receiver, and a reflector plate is installed in front. The light emitted by the light emitter is reflected back by the reflector plate and received by the light receiver. When the light path is blocked by the detected object, the light receiver cannot receive the light, thereby triggering a change in the switch signal. The mirror reflection photoelectric sensor has high detection accuracy for boundaries. For the front and rear boundary detection sensors, it can accurately determine whether the veneer material exceeds the preset boundary range in the transportation direction. For the left and right boundary detection sensors, it can also accurately detect whether the material is tilted out of position perpendicular to the transportation direction. This high-precision detection helps to quickly detect small positional deviations of the veneer during transportation, ensuring that the material always stays on the correct transportation track, which is crucial for ensuring the quality of the material and smooth warehousing.

[0076] The height measurement device consists of a transmitter and a receiver. The transmitter emits an infrared light or laser beam, and the receiver is responsible for capturing these light beams. When an object passes through the light beam, it will block part of the light. The receiver detects the change in light and calculates the height of the material by calculating the blocked light beam. It has fast measurement speed and can detect light changes and calculate height in real time during the process of the veneer passing through the light beam. For large quantities of veneer warehousing, it can quickly complete the measurement work, greatly improving the efficiency of warehousing detection.

[0077] The warehouse-in detection device provided by the embodiment of the present application further comprises an induction device and a code scanning device, wherein: the induction device is arranged at the warehouse-in opening and is used to sense whether the facing plate material reaches the warehouse-in opening; and the code scanning device is used to scan and read the product barcode information of the facing plate material located at the warehouse-in opening. The induction device can be an infrared induction sensor, which senses the facing plate material at the warehouse-in opening and can accurately determine whether the material reaches the designated position. Based on this sensing, the subsequent code scanning device and other warehouse-in operations (such as starting the warehouse-in corridor detection device) can be automatically triggered, so that the entire warehouse-in process can be orderly unfolded according to the arrival of the material, avoiding the inaccuracy and delay of manual judgment of the material position and improving the automation degree and efficiency of the warehouse-in process. After the induction device determines that the material reaches the warehouse-in opening, the code scanning device starts to work to read the product barcode information, ensuring that the barcode information is read at the right time and position, avoiding the inaccuracy or mismatch with the actual material caused by reading too early or too late, and ensuring that the collected barcode information accurately corresponds to the facing plate material that is currently being warehoused.

[0078] The embodiment of the present application further provides a facing plate warehouse-in method, comprising the following steps:

[0079] S1, a production execution system (MES) generates a facing plate material and a corresponding product barcode, and triggers a product transportation signal based on a consistent confirmation signal of the facing plate material and the corresponding product barcode.

[0080] Specifically, after the production execution system (MES) produces finished products, packages, prints finished product barcodes, and then manually determines that the barcodes are correct, the product transportation signal is triggered by pressing the “transportation corridor” start button. The production execution system (MES) generates a facing plate material and a corresponding product barcode, and triggers a product transportation signal based on a consistent confirmation signal of the two, which establishes a close association between the material and the barcode from the source, maximizes the accurate correspondence between the material and the corresponding identification information, avoids errors in subsequent processes due to identification confusion, and lays a foundation for accurate operation of the entire logistics and warehousing link.

[0081] S2, a transportation corridor starts to transport the facing plate material based on the product transportation signal, and detects the facing plate material based on a transportation corridor detection device in a facing plate warehouse-in detection device.

[0082] Specifically, the transportation corridor detection device detects the facing plate material during the transportation of the facing plate material, which can monitor the state of the material in the transportation stage in real time. This synchronous detection during transportation ensures that the material can enter the transportation stage in a timely manner after production is completed, avoiding the disruption of production rhythm caused by transportation delay and ensuring the efficient operation of the entire production supply chain.
