The term "and / or" used in the specification includes any and all combinations of one or more of the relevant listed items.

[0027] Before describing the embodiment in detail, in order to facilitate understanding of the embodiment, the structure of the T valve is briefly described first. Structurally, the T valve includes a paper core formed by stacking multiple layers of paper strips, an integrated plunger, and a shell with a spring. The paper core is the core part of the T valve and is stacked with multiple layers of high-strength wear-resistant paper material. Through precision processing and stacking, these paper strips form a solid core. The arrangement and stacking of the paper strips are strictly designed to ensure that the paper core has sufficient strength and density to meet the use requirements of the valve.

[0028] The plunger is an important part of the T valve, usually made of polymer plastic material with high strength and corrosion resistance. The plunger is precisely machined to fit closely with the paper core and the shell.

[0029] The shell is made of high-strength engineering plastic. A spring is installed inside the shell, which provides elastic support through the support and fixation of the inner wall of the shell. The top and bottom of the shell are respectively provided with connection ports for connecting with other pipes or equipment to ensure the smooth flow of the medium. The shell plays a protective and sealing role. Through the pressure of the spring, it ensures the close fit between the paper core and the plunger to prevent leakage of the medium. The shell also provides a stable supporting environment, so that the valve can work normally under various complex working conditions.

[0030] The spring is usually made of high-strength steel wire with good elasticity and durability. The spring is installed inside the housing and its position is kept stable by the fixed structure of the inner wall of the housing. The spring provides the necessary elastic force to ensure the sealing performance of the valve when it is closed and prevent the leakage of the medium. Example

[0031] like Figures 1 to 3 As shown, this embodiment discloses an exemplary structure of a plunger paper assembly machine, which specifically includes a plunger feeding detection module 201, a paper feeding assembly detection module 202, a circulating conveyor line 5, and a control host for controlling the operation of each module and the conveyor line.

[0032] Specifically, the plunger feeding detection module 201 is composed of a first vibrating discharge device, a transfer robot 203, a visual diameter detection component 204, an appearance flatness detection component 205, and a roughness detection component 206. The first vibrating discharge device discharges the plungers in sequence, and the control host intermittently (i.e., spot checks) grabs the plungers through the transfer robot 203 and sends them to the roughness detection component 206. When the test is qualified, it is sent to the visual diameter detection component 204. Similarly, after passing the test, it enters the appearance flatness detection component 205 to detect the roughness, diameter, thickness, and flatness of the plunger in turn. Detailed testing is carried out to ensure that all parameters of the plunger meet the requirements.

[0033] It is understandable that the working purpose of the plunger-paper detector 2 is to improve the detection and assembly efficiency of the plunger and paper through automated equipment, reduce manual operations, and improve product quality. In the traditional manual detection and assembly process, it is easy to have wrong detection and missed detection, while automated detection and assembly not only improves the accuracy and consistency of detection, but also greatly improves production efficiency. The sensor monitors the status of each component in real time and feeds back information to the control system to ensure the smoothness and efficiency of the entire process.

[0034] In the above structure, the main function of the transfer robot 203 is to transfer the plunger to ensure the continuity and efficiency of the production process. In terms of specific structure, the transfer robot 203 includes a three-axis mechanical arm, a gripper, a camera, and a control system, and each part cooperates with each other to achieve efficient and accurate material transfer.

[0035] During implementation, due to layout requirements, the transfer inspection is realized, and a material transfer mechanism with a slide rail cooperating with the transfer robot 203 is also included. The structure of the material transfer mechanism is conventional and only needs to achieve its transfer purpose, so it will not be described in detail.

[0036] More specifically, linear guides are the foundation of transfer robots and are usually made of high-strength steel to ensure stable and smooth movement under high loads. As the movement track of the robot arm, the guide rails are precisely machined and lubricated to withstand the rapid movement and frequent operation of the robot arm, ensuring a smooth and efficient transfer process.

[0037] The three-axis robotic arm is the executive part of the transfer robot. It has three degrees of freedom (X, Y, and Z) and can perform complex three-dimensional movements. Each joint of the robotic arm is driven by a high-precision servo motor to ensure the accuracy and stability of the movement. The material of the robotic arm is usually a lightweight and high-strength aluminum alloy to reduce its own weight and improve movement speed and responsiveness. A gripper and a camera are installed at the end of the robotic arm to grab and identify components.

[0038] The gripper is the gripping tool of the transfer robot. It is usually made of high-strength materials such as steel or carbon fiber to ensure that it can withstand large forces during the gripping process. The design of the gripper takes into account the shape and material of the component. It has an adaptive function and can adjust according to the size and shape of the component to ensure a stable grip. The gripper is equipped with a pressure sensor and a position sensor to monitor the gripping force and position in real time to prevent damage to the component.

[0039] The camera is a visual recognition tool for the transfer robot. It is usually a high-resolution industrial camera installed at the end of the robot arm or at an appropriate position to identify and locate components. The camera captures the image of the component and transmits the image information to the control host. The control host uses image processing algorithms to analyze the position and posture of the component and guide the robot arm to perform precise grasping and transfer operations.

[0040] The purpose of the transfer robot is to achieve efficient transfer of components between workstations through automation, reduce manual operations, and improve production efficiency. In traditional manual operations, the transfer of components depends on manual labor, which is not only inefficient, but also prone to operational errors, affecting the continuity of the production process and product quality. The transfer robot can greatly improve the transfer speed and accuracy, reduce the interference of human factors, and improve the overall efficiency and stability of the production line.

[0041] In a more specific structure, the main function of the roughness detection component 206 is to detect the roughness of the plunger surface to ensure that the surface quality of the plunger meets the requirements.

[0042] The first thing to understand is that roughness is the first step in spot inspection.

[0043] Structurally, it includes a testing jig and a stylus roughness tester to detect the surface roughness of the plunger. The entire testing process is coordinated by the control host and precise control is achieved through information fed back by the sensor.

[0044] The test fixture is a device used to fix and position the plunger. It is usually made of high-strength materials, such as stainless steel or hard aluminum alloy, to ensure its stability and durability during the test. The test fixture is equipped with precision clamps and positioning pins to firmly fix the plunger in the specified position to ensure that the plunger does not move or vibrate during the test.

[0045] The stylus roughness detector measures the surface roughness of the plunger by scanning with a precision stylus. The stylus is made of high-hardness material and can withstand high-frequency scanning actions to ensure the accuracy and reliability of the detection. Under the control of the electric drive device, the stylus moves on the plunger surface at a set scanning path and speed, and records the microscopic profile of the plunger surface in real time. The stylus displacement sensor converts the movement data of the stylus into an electrical signal and transmits it to the control host for processing and analysis.

[0046] The control host is responsible for receiving and processing the test data from the stylus roughness detector, and can quickly analyze the movement data of the stylus to calculate the roughness parameters of the plunger surface. According to the preset quality standards, the control host compares the test results with the standard values ​​to determine whether the surface roughness of the plunger meets the requirements.

[0047] The purpose of the test is to ensure that the surface quality of the plunger meets the technical requirements of the product. The roughness of the plunger surface directly affects the sealing performance and service life of the valve body. If the surface is too rough, it may cause the valve body to be loosely sealed, resulting in air or liquid leakage; if the surface is too smooth, it may affect the lubrication effect and accelerate wear. Therefore, through roughness testing, unqualified plungers can be effectively screened out to ensure that only plungers with qualified surface quality enter the next process, thereby improving the overall quality of the finished valve body.

[0048] Through this efficient random sampling roughness detection method, the production line can quickly screen out unqualified plungers and ensure that the plungers entering the next process in batches have good surface quality, thereby improving the efficiency of the entire production process and the final quality of the product.

[0049] In this embodiment, the visual diameter detection component 204 accurately measures the diameter of the plunger through visual technology to ensure that its size meets the predetermined specification requirements. The detection component includes a detection fixture, a light source, a camera, an image processing system and a control system, and each part cooperates with each other to achieve efficient and accurate diameter measurement.

[0050] The light source is an important part of the visual diameter detection assembly 204. It provides uniform and stable lighting conditions to ensure that the camera can clearly capture the image of the plunger. The light source is usually a high-brightness LED lamp, which has the advantages of high brightness, long life, and low energy consumption. The position and angle of the light source are aimed at eliminating shadows and reflections to ensure that the edge of the plunger is clearly visible, thereby improving measurement accuracy.

[0051] The camera measures the diameter of the plunger by capturing an image of the plunger at a fixed position at a fixed height. The camera is usually a high-resolution industrial camera that can capture the subtle features of the plunger. The camera is installed above or on the side of the inspection fixture and obtains a clear image of the plunger by cooperating with the light source. The position and focal length of the camera are precisely adjusted and fixed after adjustment to ensure the clarity and accuracy of the image.

[0052] The image processing system is integrated into the control host and is responsible for processing the images captured by the camera. Through a series of algorithms and techniques, the edge features of the plunger are extracted from the image and the diameter of the plunger is calculated. The processing process includes steps such as image acquisition, preprocessing, edge detection, feature extraction and size calculation to ensure the accuracy and stability of the measurement results.

[0053] If the measurement result is within the allowable range, the plunger is judged to be qualified and can enter the next process; if it exceeds the standard range, the plunger is judged to be unqualified and marked as NG (failed) by the system, an alarm is issued, and it waits for processing.

[0054] The purpose of visual diameter detection is to ensure that the size of the plunger meets the technical requirements, to ensure the accuracy of subsequent assembly and the quality of the product. The diameter of the plunger directly affects the assembly quality and performance of the valve body. Through accurate diameter measurement, plungers with unqualified sizes can be effectively screened out to prevent them from entering the next process, thereby improving the consistency and reliability of the product. Visual diameter detection has the advantages of high precision, high efficiency and non-contact, which can greatly improve the detection speed and accuracy and reduce errors and omissions in human detection.

[0055] In this embodiment, the paper feeding assembly detection module 202 of the plunger paper detection machine 2 includes a second vibration discharging device and a flexible feeding device 207. The second vibration discharging device discharges foam in sequence, and the flexible feeding device 207 grabs the foam and assembles it with the plunger in the carrier 501 in the specific station.

[0056] More specifically, the flexible feeding device 207 is equipped with a camera for identifying the position of the foam, and the image recognition technology is used to ensure the correct position and posture of the foam, thereby ensuring the accuracy and consistency of the assembly.

[0057] In terms of specific structure, the flexible feeding device 207 is composed of the following main components: a camera, a mechanical arm, a flexible clamp and a control system. These components cooperate with each other to ensure the accuracy and efficiency of the feeding process.

[0058] First, the camera in the flexible feeding device 207 is a key device for identifying the position of the foam. The camera is installed above and monitors the specific position and posture of the foam in real time through image acquisition technology. After the camera captures the position of the foam, it transmits the image information to the control host. The control host analyzes the position and angle of the foam through the image processing algorithm to determine the best grasping point. This process ensures that the foam can be accurately identified and located in any position and posture, providing reliable data support for subsequent grasping operations.

[0059] The robotic arm is the actuator of the flexible feeding device 207. It is mounted on a high-precision linear guide rail and can move smoothly along the guide rail. The robotic arm is equipped with a multi-axis motion module that can perform complex three-dimensional motion. This allows the robotic arm to move freely in all directions with great flexibility. A flexible clamp is installed at the end of the robotic arm. The flexible clamp is made of highly elastic material and can be adaptively adjusted according to the shape and size of the foam to ensure the stability and reliability of the grasping process. Under the command of the control host, the robotic arm moves accurately to the foam position according to the position information provided by the camera, and firmly grasps the foam through the flexible clamp.

[0060] The flexible clamp is an important component in the flexible feeding device 207. It can be fine-tuned during the grasping process through pneumatic or electric control to adapt to foams of different sizes and shapes. The design of the flexible clamp takes into account the force and angle during the grasping process to ensure that the foam will not be damaged when grasping it. The clamp is equipped with a pressure sensor and a displacement sensor to monitor the grasping force and displacement in real time and feed the data back to the control host. The control host makes real-time adjustments based on the feedback data to ensure the accuracy and stability of the grasping action.

[0061] It is understandable that the working principle of the flexible feeding device 207 is an automated process based on image recognition and precise control. First, the camera captures the position and posture of the foam and transmits the image information to the control system. The control system analyzes the image information and generates the motion trajectory of the robot arm. Under the command of the control system, the robot arm moves to the foam position, grabs the foam through the flexible clamp, and places it accurately on the plunger. The entire process is monitored and adjusted in real time by the control system to ensure the efficiency and precision of each link.

[0062] The working purpose of the flexible feeding device 207 is to achieve accurate feeding and assembly of foams through automation, thereby improving production efficiency and product quality. The traditional manual feeding method has problems such as low efficiency, poor precision, and easy errors. The flexible feeding device significantly improves the feeding precision and efficiency through automation technology and reduces the errors of manual operation. At the same time, through the flexible clamp and high-precision control system, it is ensured that the grasping and assembly of each foam can meet high quality requirements.

[0063] More specifically, the main function of the appearance flatness detection component 205 is to detect the flatness of the plunger surface to ensure that the appearance quality of the plunger meets the requirements. The detection component includes a detection fixture, a digital displacement sensor, a detection fixture fixture, a control system, etc., and each part cooperates with each other to achieve efficient and accurate appearance flatness detection.

[0064] Digital displacement sensors are used to measure the flatness of the plunger surface. Digital displacement sensors calculate the flatness value of the plunger surface by detecting the height difference between different points on the plunger surface. The sensor is installed above or on the side of the test fixture and can move vertically or horizontally during the test. The digital displacement sensor has very high accuracy and resolution, and can detect micron-level height differences to ensure the accuracy of the measurement results.

[0065] The test fixture fixture is used to fix and adjust the position of the test fixture to ensure that the fixture remains stable during the test. The fixture usually uses high-precision guide rails and locking mechanisms to accurately adjust the position of the fixture before the test begins and keep it stationary during the test. The design of the fixture takes into account the stability and repeatability of the test to ensure the reliability of each test result.

[0066] The working principle of appearance flatness detection is based on height measurement technology. The height difference of different points on the plunger surface is detected by a digital displacement sensor to achieve flatness measurement. When the plunger enters the detection station, the detection fixture fixes it in the specified position. Under the command of the control system, the digital displacement sensor begins to scan the plunger surface and record the height data of different points. The displacement data of the sensor is transmitted to the control system through electrical signals. The control host can quickly analyze this data and calculate the flatness value of the plunger surface. According to the preset quality standards, the control host compares the test results with the standard value to determine whether the flatness of the plunger meets the requirements.

[0067] The purpose of the test is to ensure that the surface flatness of the plunger meets the technical requirements of the product. The flatness of the plunger surface directly affects the assembly quality and performance of the valve body. If the surface is not flat, it may cause the valve body to be loosely assembled, resulting in air or liquid leakage. Therefore, through the appearance flatness test, plungers with unqualified surfaces can be effectively screened out, ensuring that only plungers with qualified surface flatness enter the next process, thereby improving the overall quality of the finished valve body.

[0068] In this embodiment, the main function of the paper sheet feeding assembly detection module 202 is to feed the paper sheets in order, assemble them into paper cores and perform detection to ensure the quality of the paper sheets and the accuracy of assembly. The module includes a paper sheet vibration plate 208, a PPU feeding mechanism 209, a rotary assembly plate 210, a detection component and a core shifting mechanism, and each part cooperates with each other to achieve efficient and accurate paper sheet feeding and assembly detection.

[0069] First, the paper sheet vibration plate 208 is one of the important components of paper sheet feeding. The paper sheet vibration plate 208 is driven by a motor to generate high-frequency vibration, so that the paper sheets move in sequence along the preset track. The track design of the vibration plate takes into account the size and shape of the paper sheets, which can ensure that the paper sheets will not flip or overlap during the movement, and ensure the order and stability of the paper sheets. The vibration plate sends out the paper sheets in sequence, providing a reliable foundation for subsequent feeding and assembly.

[0070] The PPU feeding mechanism 209, also known as the Pick and Place Unit, is a device responsible for grabbing paper sheets from the paper sheet vibration disk 208 and sending them to the assembly position. The PPU feeding mechanism 209 consists of a multi-axis robot arm, a flexible clamp and a control system. The multi-axis robot arm can move flexibly in three degrees of freedom. The clamp is made of flexible material and can be adaptively adjusted according to the shape and size of the paper sheet to ensure stable grabbing of the paper sheet. Under the command of the control system, the PPU feeding mechanism 209 grabs the paper sheet from the paper sheet vibration disk 208 and sends it to the designated position of the rotating assembly disk 210 according to the preset trajectory and sequence.

[0071] More specifically, the working principle of the PPU feeding mechanism 209 is based on visual recognition and precise control. The image of the paper is captured by the camera, the position and posture information of the paper is extracted by the image processing algorithm, and the control system guides the robotic arm to perform the grasping operation. After the paper sheets are arranged in order on the vibrating paper disc, the camera shoots the paper sheets, and the image processing unit analyzes the image to extract the position information of the paper sheets. Based on this information, the control system generates the motion trajectory of the robotic arm, and the robotic arm moves to the position of the paper sheet under the command of the control system. The flexible clamp is adjusted according to the thickness and shape of the paper sheet to firmly grasp the paper sheet. Subsequently, the robotic arm moves the paper sheet to the designated position of the rotating assembly disc 210 according to the preset trajectory and places it accurately. The entire process is monitored and adjusted in real time by the control system to ensure the efficiency and accuracy of each link.

[0072] The working purpose of the PPU feeding mechanism 209 is to achieve accurate feeding of paper sheets through automation, thereby improving production efficiency and product quality. In traditional manual operations, paper sheet feeding relies on manual labor, which is not only inefficient but also prone to operational errors, affecting the continuity of the production process and product quality. Through the PPU feeding mechanism, the feeding speed and accuracy can be greatly improved, the interference of human factors can be reduced, and the overall efficiency and stability of the production line can be improved.

[0073] There are several rods evenly distributed on the rotating assembly plate 210 for fixing and supporting the paper sheets. The rotating assembly plate 210 is driven by a rotating mechanism and can be accurately rotated and positioned. After the paper sheets are fed into the rods by the PPU feeding mechanism 209, multiple paper sheets are stacked together to form a paper core.

[0074] The inspection component is a device responsible for inspecting the quality of the paper core, which usually includes a visual inspection system and a pressure inspection system. The visual inspection system consists of a high-resolution camera and an image processing system, which is used to inspect the appearance quality of the paper core, such as whether the paper pieces are arranged neatly and whether there are any defects. The camera captures the image of the paper core and transmits it to the image processing system for analysis and judgment. The pressure inspection system applies a certain amount of pressure to the paper core to detect the thickness and density of the paper core to ensure that the assembly quality of the paper core meets the requirements. The design and installation position of the inspection component take into account the accuracy and stability of the inspection, and can complete high-precision inspection in a short time.

[0075] The core transfer mechanism is responsible for transferring the assembled and tested paper core to the next process. It is usually composed of a multi-axis robot, a fixture and a control system. The multi-axis robot can move flexibly in three degrees of freedom, and the fixture is made of flexible materials to firmly grasp the paper core. Under the command of the control system, the core transfer mechanism grabs the paper core from the assembly tray and transfers it to the specified position of the circulation conveyor line according to the preset trajectory and sequence. The design of the core transfer mechanism takes into account the size and shape of the paper core, which can ensure stability and accuracy during the transfer process.

[0076] When the paper feeding assembly detection module 202 is working. When the paper enters the paper vibration disk 208, the vibration disk sends the paper out in order through high-frequency vibration. Under the instruction of the control host, the PPU feeding mechanism 209 grabs the paper from the vibration disk and sends it to the designated position of the rotary assembly disk 210. After the assembly is completed, the assembly disk rotates and moves to the next station according to the preset program. The detection component inspects the appearance and thickness of the paper core to ensure that its quality meets the requirements. The core transfer mechanism transfers the qualified paper core to the next process. The entire process is monitored and adjusted in real time by the control host to ensure the efficiency and accuracy of each link.

[0077] In terms of specific structure, the circulating conveyor line 5 is mainly composed of a conveyor belt, a carrier 501, a driving device, a guide device, and a sensor. The conveyor belt is the core component of the circulating conveyor line and is made of wear-resistant and high-temperature resistant polyurethane material to ensure durability for long-term operation. The conveyor belt circulates along a preset track to form a closed-loop system. Each circulating conveyor line 5 is equipped with an independent driving device, which can control the running speed and direction individually as needed to meet the needs of different processes.

[0078] The carrier 501 is mounted on the conveyor belt and is used to carry the components to be tested and assembled. The carrier 501 is made of high-strength aluminum alloy or stainless steel to ensure stability and durability.

[0079] In implementation, as a preference, each carrier 501 is provided with positioning pins and clamps to ensure that the components do not shift or tilt during transportation.

[0080] As a further description, the driving device includes a motor, a reducer, a transmission belt, etc. The motor drives the conveyor belt to run, and the reducer adjusts the running speed to ensure that the conveyor belt runs smoothly.

[0081] More specifically, the guide device consists of guide rails and guide wheels, which ensure that the conveyor belt runs smoothly along the predetermined track. The guide rails are made of high-strength steel, and the guide wheels are connected by rolling bearings to reduce friction and wear, improve operating efficiency and life. The guide device ensures that the conveyor belt can remain stable even when running under high load and high speed.

[0082] In addition, sensors are used to detect information such as the position of the platform, component status, and operating speed to ensure accurate control of the entire conveyor line. Commonly used sensors include photoelectric sensors, magnetic induction sensors, and encoders. The sensors feed back the detected information to the control system in real time to achieve automated control and monitoring, and improve the intelligence level and response speed of the system.

[0083] The independent circulation conveyor line on each detector realizes material transfer through a transfer device. The transfer device includes a transfer robot, a transfer track and a transfer control system.

[0084] In actual operation, the independent circulation conveyor line 5 on each inspection machine drives the conveyor belt to run through the driving device, and the carrier 501 moves accordingly, and the components of each station are sequentially transferred to the corresponding position. The sensor monitors the status of the carrier and the components in real time and feeds back the information to the control host. The control host adjusts the operating parameters of the driving device according to the information fed back by the sensor to ensure the synchronization and coordination of each station.

[0085] In the specific operation steps, during the initial loading, the component (plunger) to be processed is placed on the starting platform 501 of the first circulating conveyor line 5. After the sensor detects that there is material on the platform 501, the control host starts the drive device and the conveyor belt starts to run. The platform 501 passes through each station in turn. After the sensor at each station detects that the platform 501 has arrived, the control host pauses the conveyor belt, and the station equipment starts to perform corresponding operations on the component, such as testing and assembly. After each station completes the operation, the sensor feeds back the status information of the component to the control host. The control host determines whether it meets the requirements based on the feedback information. If it does, the drive device continues to run and transfers the platform 501 to the next station; if it does not meet the requirements, the control host issues an alarm and stops running, waiting for manual processing or automatic correction.

[0086] In this embodiment, the control host is responsible for coordinating and controlling the operation of each device to ensure efficient and accurate operation of the entire system. The following is a detailed description of the control host:

[0087] The control host includes a central processing unit (CPU), storage devices, input / output modules (I / O modules), human-machine interface (HMI) and communication modules.

[0088] The central processing unit (CPU) is the core component of the control host, responsible for executing the control program, processing the data from each sensor, and generating control instructions according to the preset logic and algorithm. The CPU is usually a high-performance, multi-core processor that can handle complex control tasks and large amounts of data operations to ensure real-time response and efficient operation of the system.

[0089] Storage devices are used to store control programs, operating systems, equipment parameters, and production data. Storage devices include solid-state drives (SSDs) and memory (RAM) to ensure high-speed and stable data reading and writing. The stored production data can be used for subsequent analysis and optimization to improve system performance and efficiency.

[0090] Input / output modules (I / O modules) realize signal exchange between the control host and various devices. I / O modules include digital and analog input / output interfaces and support multiple communication protocols (such as Ethernet, RS232, RS485, CAN, etc.) to ensure compatibility with different devices. These modules can realize precise control of the entire system by collecting sensor data and sending control instructions.

[0091] The human-machine interface (HMI) provides a user operation and monitoring interface to display equipment status, production parameters, alarm information, etc. HMI usually adopts a touch screen design, with a friendly graphical interface and easy operation. Through HMI, users can view the operating status and production data of the equipment in real time, set parameters and control operations, and handle faults and alarm information.

[0092] The communication module enables data exchange between the control host and external systems (such as enterprise management systems, databases, etc.), supports wireless and wired communication methods, and has the characteristics of high bandwidth and low latency. Through the communication module, the control host can upload production data to the enterprise management system in real time to achieve remote monitoring and management.

[0093] The functions of the control host include real-time monitoring and control, data processing and storage, user operation and monitoring, alarm and fault handling, as well as system integration and data exchange. The control host receives data from each detection machine, transfer mechanism and each sensor in real time to monitor the operating status of the equipment. According to the preset control logic and algorithm, it generates and sends control instructions to coordinate the operation of each device. It processes and analyzes sensor data, identifies abnormal conditions in equipment operation, and makes corresponding adjustments. Through the human-machine interface (HMI), users can set parameters, control equipment and monitor status. The control host has a complete alarm and fault handling mechanism, which can promptly issue an alarm signal when the equipment is operating abnormally and record fault information. Through the communication module, data exchange with external systems is realized, supporting real-time uploading of production data and remote monitoring of equipment status.

[0094] The operating principle of the control host is based on real-time data acquisition, processing and feedback control. The specific operation process is as follows: The control host collects sensor data from each inspection machine, transfer mechanism and finished product plate placing machine in real time through the input / output module (I / O module). These data include the operating status of the equipment, production parameters, test results, etc. The control host processes and analyzes the collected data to identify the operating status and abnormal conditions of the equipment. The central processing unit (CPU) executes the control program and processes and calculates the data according to the preset logic and algorithm. According to the results of data processing, the control host generates corresponding control instructions. These instructions include starting or stopping the equipment, adjusting the operating parameters, triggering alarms, etc. The control instructions are sent to each device through the output module (I / O module) to control it to perform the corresponding operation. The device adjusts the state or operates according to the received instructions.

[0095] During implementation, the control host monitors the operating status of the equipment in real time, and evaluates the execution effect of the control instructions through sensor data feedback. If an abnormality or deviation is found, the control host will make adjustments according to the preset logic to ensure the stable operation of the system. Through the human-machine interface (HMI), users can view the operating status, production data and alarm information of the equipment in real time. Users can also set parameters, control equipment and handle faults through HMI. The control host stores the key data generated during the production process in the local storage device, and uploads the data to the enterprise management system or database through the communication module, supporting real-time upload of production data and remote monitoring of equipment status.

[0096] It should be understood that, within the control host, the present application is not specifically limited to a particular control software, control program or PLC control program, because these programs can be implemented using existing technology or common knowledge. Therefore, the present application does not describe the specific software, control program or PLC control program in detail.

[0097] In the prior art, the development and application of control software and PLC control programs are already very mature, and technicians can choose appropriate solutions according to specific needs to implement the functions of this application. Therefore, the core of this application lies in the improvement and innovation of the hardware structure and the overall solution, rather than the specific software implementation method.

[0098] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims.
