Description

Technical Field

[0001] This application relates to the field of servo control technology, specifically to a control method and related equipment for an edge microcrack detection and feeding machine. Background Technology

[0002] Edge micro-crack detection equipment is used to detect edge defects in LCD panels caused by processes such as cutting and grinding, and it is necessary to select out these defective LCD panels. In this detection process, the feeding machine plays a crucial role, responsible for accurately and safely transporting the LCD panels to be tested to the detection position.

[0003] Due to their fragile and easily damaged nature, LCD panels require extra care during transportation. To ensure the safety of the loading machine, related technologies typically employ complex sensor networks composed of multiple sensors to monitor the entire transportation process. While this method improves transportation safety to some extent, it also introduces new problems. In practical use, this approach often results in excessively slow transportation speeds, failing to meet the high-efficiency requirements of modern production lines. Therefore, how to improve transportation efficiency while ensuring safety has become a pressing technical challenge. Summary of the Invention

[0004] This application provides a control method and related equipment for an edge microcrack detection feeding machine, which can ensure the feeding machine's efficiency in transporting LCD panels while improving transportation safety.

[0005] In a first aspect, this application provides a control method for an edge microcrack detection feeding machine, the method comprising: In response to the feeding command, the feeder is controlled to transport the LCD panel in a position mode; When the LCD panel is detected to have reached the preset waiting point, the feeder is controlled to switch to torque mode to transport the LCD panel, and the feeder is controlled to extend the stop block. The transport accuracy of the torque mode is greater than that of the position mode. When the LCD panel is detected to have reached the endpoint or when the LCD panel is detected to have touched the stop block, the feeder is controlled to stop conveying and retract to the stop block.

[0006] By adopting the above technical solution, the initial stage uses a position-based transport mode, ensuring that the LCD panel can quickly and stably reach the preset waiting point. When the LCD panel arrives at the waiting point, the system flexibly switches to torque mode, utilizing its higher transport accuracy to lay the foundation for precise positioning of the LCD panel. Simultaneously, the feeder extends a stop block, providing a clear physical reference point for the LCD panel. This dynamically switching control method not only optimizes transport efficiency but also significantly improves positioning accuracy near the destination. Finally, by accurately detecting whether the LCD panel has reached the destination or touched the stop block, the system can promptly stop transport and retract the stop block, effectively balancing speed and accuracy requirements during transport and improving the reliability and efficiency of the entire loading process.

[0007] Optionally, when the LCD panel is detected to have reached the endpoint, controlling the feeder to stop conveying and retract the stop block includes: To determine whether the photoelectric sensor has detected the feedback signal corresponding to the LCD panel, the photoelectric sensor is set at the endpoint position; When the photoelectric sensor detects the feedback signal corresponding to the liquid crystal panel, it controls the feeding machine to stop conveying and retract to the stop block.

[0008] By adopting the above technical solution, when the LCD panel is transported to the destination position, the photoelectric sensor can instantly detect its presence and generate a corresponding feedback signal. The system can accurately identify whether the LCD panel has reached the predetermined position by judging this feedback signal. Once the LCD panel is confirmed to be in place, the system immediately controls the feeding machine to stop transporting and simultaneously triggers the retraction of the stop block. This precise detection and rapid response mechanism based on photoelectric sensing not only improves the accuracy of LCD panel positioning but also significantly reduces the risk of overshoot or undershoot.

[0009] Optionally, before controlling the feeder to stop conveying and retract to the stop block when the LCD panel is detected to have reached the endpoint or when the LCD panel touches the stop block, the method further includes: The transport distance between the waiting point and the destination point, and the transport efficiency of the loading machine for the LCD panel are obtained. Based on the transport distance and the transport efficiency, a transport plan for the liquid crystal panel between the waiting point and the destination point is determined.

[0010] By adopting the above technical solution and through precise calculations, the system can determine the optimal speed curve, acceleration, and deceleration parameters. This ensures that the LCD panel reaches its destination in the shortest possible time while avoiding potential damage to the LCD panel caused by rapid acceleration or deceleration. This intelligent conveying solution not only improves the efficiency of the loading process but also enhances the system's adaptability to different conveying conditions.

[0011] Optionally, the transportation scheme includes a constant-speed transportation scheme and a variable-speed transportation scheme. Determining the transportation scheme for the LCD panel between the waiting point and the destination point based on the transportation distance and the transportation efficiency includes: Based on the transport distance and the transport efficiency, a uniform speed transport scheme for the liquid crystal panel between the waiting point and the destination point is determined. The uniform speed transport scheme includes a uniform speed transport speed and a uniform speed transport duration. Based on the constant speed transport speed and the constant speed transport duration, a variable speed transport scheme for the liquid crystal panel is determined, and the variable speed transport scheme includes transport acceleration.

[0012] By adopting the above technical solution, the system calculates the optimal uniform-speed transport scheme based on the transport distance and efficiency, determining the appropriate uniform-speed transport speed and duration. This uniform-speed transport strategy not only ensures the stability of the LCD panel during the main transport phase but also effectively reduces energy consumption. Subsequently, based on the determined uniform-speed transport parameters, the system further develops a variable-speed transport scheme, accurately calculating the transport acceleration. This variable-speed strategy optimizes the start-up and stopping process of the LCD panel, reducing the potential impact of sudden acceleration or deceleration. By organically combining the uniform-speed and variable-speed schemes, the system achieves a smooth transition in the transport process, ensuring transport efficiency while minimizing the potential damage risk to the LCD panel.

[0013] Optionally, after controlling the feeder to retract to the stop block, the method further includes: Obtain the actual retraction time of the stop block to its initial position; The target retraction time for the stop block to return to its initial position is determined based on the transport efficiency. If the actual retraction time is not less than the target retraction time, the auxiliary reset device of the stop block is activated to shorten the actual retraction time of the stop block.

[0014] By adopting the above technical solution, the system first obtains the actual retraction time of the stop block to its initial position, and calculates the ideal target retraction time based on the conveying efficiency of the feeder. By comparing these two time parameters, the system can accurately evaluate the efficiency of the stop block retraction process. When the actual retraction time is not less than the target retraction time, the system will promptly activate the auxiliary reset device of the stop block, effectively shortening the actual retraction time. This intelligent retraction control mechanism not only ensures that the stop block can return to its initial position in the shortest possible time, but also effectively avoids the decrease in overall feeding efficiency that may be caused by the delay in the stop block's retraction. At the same time, the introduction of the auxiliary reset device provides additional power for the rapid reset of the stop block, significantly improving the retraction speed while ensuring retraction accuracy.

[0015] Optionally, when the LCD panel is detected to have reached a preset waiting point, controlling the feeder to switch to torque mode to transport the LCD panel, and controlling the feeder to extend the stop block, includes: Obtain the physical characteristic data of the liquid crystal panel and the initial torque parameters of the torque mode; The initial torque parameters are adjusted based on the LCD panel characteristic data to obtain the target torque parameters of the torque mode.

[0016] By adopting the above technical solution, this parameter optimization method based on actual data enables the loading machine to provide the most suitable torque control for each LCD panel, ensuring the stability and accuracy of the transportation process while minimizing the potential risk of damage to the LCD panels. Through this dynamic adjustment mechanism, the system can flexibly handle LCD panels of different specifications and materials, greatly improving the adaptability and versatility of the loading system.

[0017] Optionally, controlling the extension of the stop block by the feeder includes: Obtain the size data of the liquid crystal panel to determine the extension height and extension position of the stop block; The feeder is controlled to extend the stop block according to the extension height and extension position.

[0018] By adopting the above technical solution and precisely controlling the extension parameters of the stop blocks, the system can provide the most suitable physical positioning point for each LCD panel, greatly improving the positioning accuracy of the LCD panel at the endpoint. This intelligent stop block control strategy not only enhances the adaptability of the feeding system to LCD panels of different sizes, but also improves the stability and reliability of the entire feeding process.

[0019] Secondly, this application provides a control system for an edge microcrack detection and feeding machine, the system comprising: The first conveying module is used to respond to the feeding command and control the feeder to convey the LCD panel in a position mode; The second conveying module is used to control the feeder to switch to torque mode to convey the LCD panel when the LCD panel is detected to have reached a preset waiting point, and to control the feeder to extend the stop block. The stop module is used to control the feeder to stop conveying and retract to the stop block when it is detected that the LCD panel has reached the end point or that the LCD panel has touched the stop block.

[0020] Thirdly, this application provides a computer storage medium storing a plurality of instructions adapted for loading by a processor and executing any of the methods described above.

[0021] Fourthly, this application provides an electronic device including a processor, a memory, and a transceiver, wherein the memory is used to store instructions, the transceiver is used to communicate with other devices, and the processor is used to execute the instructions stored in the memory to cause the electronic device to perform any of the methods described above.

[0022] In summary, the beneficial effects of the technical solution of this application include: By adopting the above technical solution, the initial stage uses a position-based transport mode, ensuring that the LCD panel can quickly and stably reach the preset waiting point. When the LCD panel arrives at the waiting point, the system flexibly switches to torque mode, utilizing its higher transport accuracy to lay the foundation for precise positioning of the LCD panel. Simultaneously, the feeder extends a stop block, providing a clear physical reference point for the LCD panel. This dynamically switching control method not only optimizes transport efficiency but also significantly improves positioning accuracy near the destination. Finally, by accurately detecting whether the LCD panel has reached the destination or touched the stop block, the system can promptly stop transport and retract the stop block, effectively balancing speed and accuracy requirements during transport and improving the reliability and efficiency of the entire loading process.

[0028] Please see Figure 1 This is a flowchart illustrating a control method for an edge microcrack detection and feeding machine provided in an embodiment of this application. This method can be implemented using a computer program, a microcontroller, or run on a control system of the edge microcrack detection and feeding machine based on the von Neumann architecture. The computer program can be integrated into the application or run as a standalone utility application. The specific steps of the control method for the edge microcrack detection and feeding machine are described in detail below.

[0029] S101: In response to a feeding command, control the feeder to transport the LCD panel in position mode.

[0030] The loading command is a start signal issued by the control system to the loading machine to trigger the loading process of the LCD panel. In this embodiment, it can be understood as a command signal used to start and control the entire LCD panel transport process. Specifically, the loading command is used to start the loading machine, set the initial transport mode, and trigger a series of subsequent control steps. When the system receives the loading command, the loading machine starts working, preparing to transport the LCD panel. This command typically includes the setting of the initial transport mode, such as the position mode in this embodiment, as well as some initial parameter settings, such as the initial transport speed and acceleration. In automated production lines, the issuance of the loading command is usually coordinated with the rhythm of the entire production line to ensure that the LCD panel can reach the detection position in a timely manner.

[0031] In this context, a loading machine refers to a mechanical device used in automated production lines for conveying and positioning workpieces. In the embodiments of this application, it can be understood as an automated device specifically designed for transporting and precisely positioning LCD panels. Specifically, the loading machine is used to safely and accurately transport the LCD panel to be inspected from its initial position to the inspection position.

[0032] The "position mode" refers to a control method employed by the loading machine when transporting LCD panels, primarily based on position information to adjust movement. In this embodiment, it can be understood that the loading machine achieves the initial transport of the LCD panel by precisely controlling the movement distance and position. Specifically, the position mode controls the loading machine to accurately move the LCD panel from its starting position to a preset waiting point. In this mode, the loading machine mainly executes its movement based on pre-set position parameters, such as the movement distance and target position. This mode ensures that the LCD panel remains stable and controllable during the initial transport phase, effectively avoiding positional deviations caused by speed changes or external interference.

[0033] In this embodiment, when the control system receives a loading command, it first responds to the command and controls the loading machine to transport the LCD panel in position mode. Specifically, the control system initiates the loading machine's movement based on the initial parameter settings included in the loading command, such as the initial transport speed and acceleration. The loading machine then begins transporting the LCD panel in position mode, meaning it primarily controls its movement based on preset position information. During this process, the loading machine's control system monitors the current position of the LCD panel in real time and compares it with the target position, thereby precisely adjusting the motion parameters to ensure the LCD panel moves along a predetermined trajectory. The position mode is chosen as the initial transport method because it provides higher precision control, effectively preventing positional deviations or unnecessary vibrations of the LCD panel during transport.

[0034] S102: When the LCD panel is detected to have reached the preset waiting point, the feeder is controlled to switch to torque mode to transport the LCD panel, and the feeder is controlled to extend the stop block. The transport accuracy of torque mode is greater than that of position mode.

[0035] Here, the waiting point refers to a specific location during the transport of the LCD panel. In this embodiment, it can be understood as the point at which the position mode and torque mode switch when the loading machine transports the LCD panel. Specifically, the waiting point is used to mark the transition position of the loading machine's control strategy. When the LCD panel reaches this preset waiting point, the loading machine's transport mode will switch from position mode to torque mode.

[0036] The torque mode refers to a torque-based motion control method used by the loading machine when transporting LCD panels. In this embodiment, it can be understood that the loading machine achieves smoother and more precise transport control by accurately adjusting the torque applied to the LCD panel. Specifically, the torque mode provides more accurate and sensitive motion control when the LCD panel approaches the final detection position. In this mode, the loading machine mainly adjusts its motion state based on real-time torque data, rather than relying solely on position information. The torque mode enables precise control of the force applied to the LCD panel, allowing the loading machine to move the LCD panel to its final position with less force and in a smoother manner.

[0037] A stop block, in this context, refers to a device used in mechanical equipment to restrict or stop the movement of an object. In this embodiment, it can be understood as a controllable mechanical structure installed on a loading machine for precisely positioning and fixing a liquid crystal panel. Specifically, the stop block provides a physical barrier when the liquid crystal panel is transported to a predetermined position, ensuring that the liquid crystal panel remains in the correct detection position. This stop block typically employs a retractable design, capable of extending or retracting according to control commands. When the liquid crystal panel approaches its final position, the stop block extends to prevent further movement, thereby achieving precise positioning. The stop block's design takes into account the fragility of the liquid crystal panel, typically using a soft cushioning material on the contact surface to reduce potential damage to the edges of the liquid crystal panel. By using the stop block, this embodiment further improves the accuracy and stability of liquid crystal panel positioning based on torque mode control.

[0038] In this embodiment, to provide more precise and safer transport control as the LCD panel approaches the final detection position, when the loading machine detects that the LCD panel has reached the preset waiting point, it switches to torque mode to continue transporting the LCD panel and simultaneously extends a stop block. Specifically, when the LCD panel reaches the waiting point, the loading machine's control system immediately switches the transport mode from position mode to torque mode. In torque mode, the loading machine no longer primarily relies on position information to control its movement, but adjusts its movement based on real-time torque data fed back from the torque sensor. This switching enables precise control of the force applied to the LCD panel, allowing the loading machine to move the LCD panel to its final position with less force and in a smoother manner. Simultaneously, the system controls the loading machine to extend the stop block, preparing a precise stopping position for the approaching LCD panel. The reason for switching to torque mode and extending the stop block at this moment is that it provides higher safety and accuracy during the final stage of LCD panel transport. The torque mode effectively reduces impacts and vibrations caused by inertia or sudden stops, while the extended stop provides a precise physical limit for the LCD panel. This combined operation not only ensures that the LCD panel is transported accurately and safely to the final inspection position, but also minimizes potential damage to the fragile LCD panel.

[0039] In this embodiment, the torque mode of the loading machine achieves higher accuracy in transporting the LCD panel than the position mode. This is due to the differences in control principles and application scenarios between the two modes. The position mode primarily relies on encoder feedback and preset position commands to control movement, making it suitable for long-distance, high-speed transport, but it may suffer from cumulative errors during precise positioning. In contrast, the torque mode achieves movement by directly controlling the motor's output torque, enabling a more accurate response to changes in external forces, and is particularly suitable for short-distance, low-speed precision positioning requirements.

[0040] In this solution, the loading machine first rapidly transports the LCD panel to the waiting position in position mode. When the LCD panel is detected to have reached the preset waiting position, the loading machine automatically switches to torque mode and extends a stop block. In torque mode, the loading machine slowly pushes the LCD panel by precisely controlling the motor's output torque until it contacts the stop block or reaches the endpoint. This method effectively avoids overshoot or oscillation of the LCD panel during the final positioning process, thus achieving higher positioning accuracy.

[0041] In practice, the feeding machine's control system dynamically adjusts the target torque parameters of the torque mode based on the physical characteristics of the LCD panel and the initial torque parameters. This ensures optimal conveying performance on LCD panels of different sizes. Simultaneously, the extension height and position of the stop blocks are precisely adjusted according to the LCD panel's dimensions, further improving positioning accuracy.

[0042] Based on the above embodiments, as an optional implementation method, the step of controlling the feeder to extend the stop block further includes S201-S202.

[0043] S201: Obtain the size data of the LCD panel and determine the extension height and position of the stop block.

[0044] The dimensional data of the liquid crystal panel refers to a set of specific measurements describing the physical characteristics of the liquid crystal panel. In this embodiment, it can be understood as a set of numerical parameters used to accurately describe the geometric characteristics of the liquid crystal panel to be tested. Specifically, the dimensional data of the liquid crystal panel is used to provide accurate reference information for the loading machine and testing equipment to optimize the transportation and testing process. This data typically includes key dimensions such as the length, width, thickness, and possible diagonal length of the liquid crystal panel. In addition, it may also include relevant parameters such as the weight and edge shape of the panel. In practical applications, these dimensional data may vary depending on the model of the liquid crystal panel.

[0045] The extension height of the stop block refers to the vertical distance from its retracted state to its fully extended state. In this embodiment, it can be understood as the vertical height of the top of the stop block relative to the reference plane of the loading machine when it rises to block and position the LCD panel. Specifically, the extension height of the stop block is used to ensure accurate positioning and fixing of LCD panels of different thicknesses. This height parameter directly affects the position of the contact point between the stop block and the LCD panel, thus determining the accuracy of the LCD panel's detection position. The extension height of the stop block can typically be dynamically adjusted according to the thickness of the LCD panel to accommodate panels of different specifications.

[0046] The extension position of the stop block refers to its specific spatial location on the feeder. In this embodiment, it can be understood as the preset coordinate position of the stop block relative to the feeder and the LCD panel transport path. Specifically, the extension position of the stop block is used to accurately determine the final stopping point of the LCD panel on the inspection equipment. The extension position of the stop block is usually preset based on the size data of the LCD panel and the layout of the inspection equipment to ensure that the LCD panel can be accurately placed in the optimal inspection area. By precisely controlling the extension position of the stop block, this embodiment can achieve adaptive positioning of LCD panels of different sizes.

[0047] In this embodiment, to achieve precise positioning and fixing of LCD panels of different specifications, the feeding machine control system first acquires the size data of the LCD panel to be inspected, and then determines the extension height and position of the stop block based on this data. Specifically, the control system can acquire the size data of the LCD panel, including key parameters such as length, width, and thickness, through a pre-entered database or real-time measurement. Based on this data, the system performs a series of calculations to determine the most suitable extension height and position of the stop block for the current LCD panel. When determining the extension height, the system considers the thickness of the LCD panel to ensure that the stop block is flush with the edge of the LCD panel, providing sufficient blocking force without applying excessive pressure to the panel. When determining the extension position, the system combines the length and width of the LCD panel with the layout of the inspection equipment to calculate the coordinates that allow the LCD panel to be precisely positioned in the optimal inspection area. In this way, each LCD panel can be precisely placed in the same relative position, ensuring the consistency and comparability of the inspection results.

[0048] Based on the above embodiments, as an optional implementation method, the torque parameters corresponding to the torque mode in actual use can be adjusted by feedback in the following manner, and the specific adjustment steps include S301-S302.

[0049] S301: Obtain physical characteristic data of the LCD panel and initial torque parameters of the torque mode.

[0050] The physical property data of the liquid crystal panel refers to a set of parameters describing the material properties and mechanical behavior of the liquid crystal panel. In the embodiments of this application, it can be understood as a set of numerical parameters used to accurately describe the physical properties of the liquid crystal panel to be tested. These parameters directly affect the performance of the liquid crystal panel during transportation. By pre-inputting or measuring these physical property data in real time, the control system can more accurately adjust the transportation parameters of the feeder. For example, based on the mass of the panel and the elastic modulus of the material, the system can accurately calculate the force required to be applied under torque mode; based on the surface friction coefficient, the acceleration and deceleration processes can be optimized.

[0051] The initial torque parameter refers to the motor output torque value initially set by the feeder in torque mode. This parameter is a pre-set reference value used to control the initial force with which the feeder pushes the LCD panel in torque mode. Specifically, the initial torque parameter can be understood as the minimum torque value that can safely and effectively push the LCD panel under standard operating conditions. This parameter is usually set based on the most common LCD panel specifications, aiming to provide a universal starting point for subsequent adjustments based on the characteristics of different LCD panels. In this embodiment, the initial torque parameter is mainly used as a reference value when starting torque mode. When the feeder switches from position mode to torque mode, the system first applies this initial torque parameter to ensure that the LCD panel can start moving smoothly.

[0052] In this embodiment, to adapt to LCD panels of different specifications and characteristics and ensure the accuracy and stability of the loading process, the physical characteristic data of the LCD panels and the initial torque parameters of the torque mode are acquired to achieve precise control over the loading of the LCD panels. Specifically, the physical characteristic data of the LCD panels includes, but is not limited to, key parameters such as panel weight, size, and surface friction coefficient. This data can be acquired in various ways, such as reading preset panel specification information from the central database of the production line, or dynamically collecting data during the loading process using real-time measurement equipment. Meanwhile, the initial torque parameters of the torque mode are a baseline value preset by the system, typically set based on the most common LCD panel specifications. When an LCD panel enters the loading system, the system first reads the physical characteristic data corresponding to the panel model. If it is a new model panel, the system will activate the real-time measurement module to quickly acquire the necessary physical characteristic data through devices such as weight sensors and size scanners. Simultaneously, the system retrieves the initial torque parameters of the torque mode from the control parameter library. This initial torque parameter is set based on a large amount of historical data and empirical values, representing the minimum torque value required to safely and effectively push the LCD panel under standard conditions.

[0053] S302: Adjust the initial torque parameters according to the LCD panel characteristic data to obtain the target torque parameters of the torque mode.

[0054] The target torque parameter refers to the optimal motor output torque value dynamically adjusted by the feeder in torque mode based on the specific physical characteristics of the current LCD panel. This parameter is obtained by optimizing the initial torque parameter in conjunction with the actual conditions of the LCD panel. The target torque parameter can be understood as a precisely calculated torque value for a specific LCD panel that achieves the best conveying effect. It comprehensively considers the physical characteristics of the LCD panel, such as its weight, size, and surface friction coefficient, as well as the actual conditions of the current conveying environment. The target torque parameter is mainly used to precisely control the operation of the feeder in torque mode. When the feeder switches from position mode to torque mode, the control system immediately applies this target torque parameter to ensure that the most suitable thrust is applied to the LCD panel.

[0055] In this embodiment, the system first acquires the physical characteristic data of the current LCD panel, including key parameters such as weight, size, and surface friction coefficient. Then, the system compares and calculates this data with a pre-set initial torque parameter. The adjustment process is implemented through a complex algorithm. First, the system calculates the proportion of difference in various physical characteristics between the current LCD panel and the standard panel (i.e., the panel corresponding to the initial torque parameter). Then, based on these proportions, the system makes a corresponding weighted adjustment to the initial torque parameter. For example, if the weight of the current panel is 1.2 times that of the standard panel, the system may increase the initial torque parameter by 20% as a basic adjustment. Next, the system considers other factors, such as the influence of the friction coefficient, and may make further fine adjustments. Finally, the system compares the adjusted parameter with a preset safety threshold to ensure that the target torque parameter is within a safe range.

[0056] S202: Control the extension stop block of the feeder according to the extension height and extension position.

[0057] In practice, the system first calculates the most suitable stop block extension height and position based on the physical characteristics of the current LCD panel, especially its dimensions. This calculation process takes into account the panel's thickness, width, and minor deviations that may occur during transportation. For example, for thicker panels, the system will increase the stop block extension height accordingly to ensure effective panel blocking; for wider panels, the system will adjust the stop block extension position to provide a wider support area.

[0058] The process of controlling the extension of the stop block is achieved through a precision actuator. The feeder is equipped with a high-precision servo motor and position sensor, enabling precise control of the stop block's movement. After the system calculates the optimal extension height and position, it transmits these parameters to the actuator. Based on these parameters, the servo motor drives the stop block to move precisely to the designated position. Simultaneously, the position sensor monitors the actual position of the stop block in real time. If any deviation is detected, the system immediately makes fine adjustments to ensure that the stop block's position perfectly matches the preset parameters.

[0059] S103: When the LCD panel is detected to have reached the endpoint or when the LCD panel is detected to have touched the stop block, the feeder is controlled to stop conveying and retract to the stop block.

[0060] The endpoint refers to the final stopping position of the LCD panel after it has been transported on the loading machine. This position is precisely preset and represents the target endpoint of the LCD panel transportation process. The endpoint is mainly used as the target position during the LCD panel transportation process. When transporting the LCD panel, the loading machine uses this endpoint as the final positioning target to ensure that the panel can accurately stop at the predetermined position.

[0061] In this embodiment, when the LCD panel is detected to have reached the endpoint or touched the stop block, the feeding machine is controlled to stop transporting and retract the stop block. This is primarily to precisely control the current stopping position of the LCD panel, and secondly, to create conditions for transporting the next LCD panel by retracting the stop block. Specifically, the system monitors the position and status of the LCD panel in real time using a position sensor and a force sensor on the stop block. When the panel is detected to have reached the preset endpoint or contacted the stop block, the system immediately sends a stop signal.

[0062] Upon receiving a stop signal, the feeder's drive system rapidly but smoothly decelerates until it comes to a complete stop, ensuring the LCD panel is precisely positioned at the target location. After the stop is completed, the system immediately activates the stop block's retraction mechanism. This retraction action clears the transport path, preparing for the transport of the next LCD panel. The retraction mechanism is driven by a precision servo motor, enabling rapid and accurate position control to ensure the stop block is completely removed from the transport path.

[0063] Please see Figure 2 This is a schematic diagram of the control process for a feeding machine provided in an embodiment of this application.

[0064] The diagram illustrates the operation of the automated feeder in this embodiment, primarily used for feeding LCD panels or similar materials. The process begins by determining if there is material available for processing; if not, it waits in a loop. When material is ready and the feeder needs to feed it, the system checks if the material has reached the predetermined waiting position. If the material is not in the waiting position, the system moves it to the correct position using a servo motor in position mode. Subsequently, the feeder switches to speed-torque mode, likely for more precise control of force and speed in subsequent operations. Next, a stop block extends in the mechanism, possibly to secure or guide the material, while the servo motor switches to torque mode to ensure appropriate force is applied during material movement. The system then uses photoelectric sensors and physical contact detection to confirm that the material has reached the designated position and is in contact with the stop block; these two detection steps are likely to ensure accurate material positioning. Once the material is confirmed to be correctly positioned, the servo motor stops, marking the completion of the feeding process. Finally, the stop block returns to its original position, preparing for the next operation.

[0065] Based on the above embodiments, as an optional implementation method, it is determined whether the photoelectric sensor detects the feedback signal corresponding to the liquid crystal panel. The photoelectric sensor is set at the endpoint position. When the photoelectric sensor detects the feedback signal corresponding to the liquid crystal panel, the feeder is controlled to stop conveying and retract to the stop block.

[0066] In practice, a photoelectric sensor is cleverly installed at a predetermined endpoint, with its transmitter and receiver forming a precise beam barrier. When the LCD panel reaches the endpoint, this beam is interrupted, triggering the sensor to generate a feedback signal. This method utilizes the high sensitivity and fast response characteristics of photoelectric technology, enabling the accurate detection of the LCD panel's position within microseconds. The system determines whether the LCD panel has reached the endpoint by monitoring the output signal of the photoelectric sensor in real time. Once a feedback signal is detected, the control system immediately executes two key actions: first, it sends a stop command to the feeder, causing it to stop its transport quickly but smoothly; second, it activates the retraction mechanism of the stop block.

[0067] Based on the above embodiments, as an optional implementation method, steps S401-S402 are further included before step S103.

[0068] S401: Obtain the transport distance between the waiting point and the destination point, as well as the transport efficiency of the feeder for the LCD panel.

[0069] The transport distance refers to the straight-line distance that the LCD panel travels from its initial position to its final position on the loading machine. This distance represents the total length of the LCD panel that it moves along a predetermined track during transport.

[0070] In this embodiment, transport efficiency refers to the ability of a liquid crystal panel to be transported from its initial position to its final position on the loading machine within a unit of time. This indicator comprehensively reflects the loading system's ability to achieve rapid transport while ensuring accuracy. In this embodiment, transport efficiency can be understood as a composite indicator, typically expressed as the number of panels per time (e.g., panels per minute).

[0071] In practice, the system first obtains the transport distance between the waiting point and the destination point using precise measuring equipment or preset parameters. This distance can be measured using a high-precision laser rangefinder or calculated based on system design parameters and CAD models. For obtaining transport efficiency, the system comprehensively considers multiple factors, including the maximum speed and acceleration performance of the feeder, the weight and size characteristics of the LCD panels, and the overall cycle time requirements of the production line. Transport efficiency can be determined through historical data analysis or real-time monitoring, typically expressed as the number of LCD panels transported per unit time or the transport distance per unit time. Simultaneously, the system uses a high-precision encoder to monitor the feeder's movement status in real time, combining this with timestamp data to calculate the actual transport efficiency.

[0072] S402: Determine the transportation plan for the LCD panel between the waiting point and the destination point based on the transportation distance and transportation efficiency.

[0073] The conveying plan refers to a comprehensive set of strategies and parameters that guide the loading machine in accurately and efficiently transporting LCD panels from the waiting point to the destination point. This plan covers all key aspects and control parameters throughout the entire conveying process. The control system generates detailed motion commands based on parameters defined in the conveying plan, such as speed curves, acceleration, and deceleration values, ensuring that the LCD panels move smoothly and accurately from the waiting point to the destination point. Furthermore, the conveying plan serves as a crucial tool for optimizing production efficiency. By adjusting various parameters within the plan, conveying efficiency can be maximized while ensuring safety and quality, thereby increasing the overall production line capacity.

[0074] In practice, the system first processes the acquired transport distance and efficiency data using advanced algorithms. This process involves complex mathematical models and optimization algorithms, such as particle swarm optimization or genetic algorithms, to find the optimal combination of motion parameters. The system considers several key factors, including acceleration curves, maximum speed, deceleration strategies, and precise stopping control. When determining the transport plan, the system first calculates the ideal speed curve based on the transport distance. This curve typically includes acceleration, constant speed, and deceleration phases. The design of the acceleration phase needs to consider the physical characteristics of the LCD panel to ensure that acceleration does not damage the panel. The speed of the constant speed phase is determined based on the transport efficiency requirements and equipment capabilities. The design of the deceleration phase is particularly critical, requiring that the panel can stop smoothly and accurately at the endpoint. Simultaneously, the system adjusts the parameters of each motion phase according to the transport efficiency requirements. For example, if increased transport efficiency is needed, the system may increase acceleration or maximum speed, but will also correspondingly extend the deceleration distance to ensure accurate positioning. Conversely, if higher accuracy is required, the system may choose a relatively gentle acceleration and a lower maximum speed in exchange for higher positioning accuracy.

[0075] Based on the above embodiments, as an optional implementation method, step S402 further includes S501-S502.

[0076] S501: Based on the transport distance and transport efficiency, determine the uniform speed transport scheme for the LCD panel between the waiting point and the destination point. The uniform speed transport scheme includes the uniform speed transport speed and the uniform speed transport duration.

[0077] The uniform speed transport scheme refers to a servo control scheme that maintains a constant speed during the transport process between the waiting point and the destination point. Through precise servo control, the movement speed of the LCD panel remains constant throughout the entire uniform speed phase, thereby reducing the risks associated with speed fluctuations. This precise servo control enables stable and reliable transport of the LCD panel between the waiting point and the destination point. This scheme not only ensures the smoothness of the transport process but also provides crucial support for the efficient operation of the entire loading system.

[0078] In this embodiment, a uniform-speed transport scheme for the LCD panel between the waiting point and the destination point is determined based on the transport distance and transport efficiency. This scheme mainly includes two core parameters: uniform-speed transport speed and uniform-speed transport duration. The purpose of this step is to develop an optimized execution plan for the uniform-speed phase of the loading process to ensure the safe and stable transport of the LCD panel while meeting production efficiency requirements.

[0079] In practice, the system first processes the acquired transport distance and efficiency data. Transport distance directly affects the duration of uniform-speed transport, while transport efficiency determines the average speed required for the entire process. Using these two key inputs, combined with the performance parameters of the feeder and the physical characteristics of the LCD panel, the system calculates the optimal uniform-speed transport speed and corresponding uniform-speed transport duration through an optimization algorithm. During the calculation, the system considers several factors. First, the uniform-speed transport speed must meet the transport efficiency requirements while not exceeding the safe operating speed limit of the feeder. Second, the uniform-speed transport duration needs to be coordinated with the overall time budget of the transport process, reserving sufficient time and distance for acceleration and deceleration phases. Through iterative calculations, the system finds the optimal combination of speed and duration that satisfies both transport efficiency requirements and ensures smooth movement.

[0080] S502: Determine the variable speed transport scheme for the LCD panel based on the constant speed transport speed and the constant speed transport duration. The variable speed transport scheme includes transport acceleration.

[0081] The variable speed transport scheme refers to the speed control scheme for all non-uniform speed stages during the transport of the LCD panel between the waiting point and the destination point. In the embodiments of this application, the variable speed transport scheme can be understood as a complex, multi-stage speed control strategy, including but not limited to initial acceleration, initial deceleration, intermediate speed adjustment, and final deceleration stages, used to achieve accurate, safe, and efficient transport of the LCD panel from the waiting point to the destination point.

[0082] In this embodiment, the necessity of determining a variable-speed transport scheme stems from the complex requirements of the liquid crystal panel transport process. Uniform-speed transport alone cannot meet the requirements of the entire transport process, as it involves transitions from stationary to moving and from moving to stationary, as well as possible intermediate speed adjustments. The introduction of a variable-speed transport scheme can effectively handle these non-uniform speed phases, ensuring the smoothness and efficiency of the transport process.

[0083] In practice, the total distance the LCD panel needs to be transported is first calculated based on the known constant speed and duration of the transport. Then, considering the acceleration and deceleration requirements throughout the transport process, the total transport time is allocated to the acceleration phase, the constant speed phase, and the deceleration phase. Based on this, an appropriate transport acceleration is determined.

[0084] Based on the above embodiments, as an optional implementation method, steps S402 are further included in steps S601-S603.

[0085] S601: Obtain the actual retraction time of the stop block to its initial position.

[0086] The actual retraction time refers to the actual time required for the stop block to return from its fully extended state to its initial position. In this embodiment, it can be understood as the time interval from when the control system issues a retraction command to when the stop block fully returns to its preset initial position. This time can be accurately measured by devices such as sensors or encoders.

[0087] In this embodiment, after the feeder completes the task of transporting the LCD panel, the control system issues a command to return the stop block to its initial position. To accurately monitor this process, the system uses a high-precision sensor or encoder to track the position change of the stop block in real time. Specifically, when the system issues a return command, a timer starts counting; when the position sensor detects that the stop block has completely returned to the preset initial position, the timer stops, thus obtaining the accurate actual return time.

[0088] S602: Determine the target return time for the stop block to return to its initial position based on the transport efficiency.

[0089] The target retraction time refers to the ideal or expected time for the stop block to return from its fully extended state to its initial position. In this embodiment, it can be understood as the standard stop block retraction time calculated based on the conveying efficiency of the feeder and system optimization requirements. This time is an ideal value determined by comprehensively considering factors such as equipment performance parameters, production cycle requirements, and overall system efficiency.

[0090] In this embodiment, the conveying efficiency of the feeder reflects the overall performance of the equipment and the production cycle requirements, thus it is of great significance as the basis for determining the target return time. Specifically, the system first acquires the conveying efficiency data of the feeder, including the conveying speed and acceleration of the LCD panel, as well as the total time to complete one feeding cycle. Based on this data, the system uses a preset algorithm to calculate the optimal stop block return time. This algorithm considers multiple factors, such as the size and weight of the LCD panel, the mechanical characteristics of the feeder, and the overall cycle requirements of the production line. The target return time determined in this way ensures that the stop block return process is coordinated with the entire feeding cycle, avoiding delays in the next feeding due to slow return, or unnecessary energy consumption and mechanical wear due to excessively fast return.

[0091] S603: If the actual retraction time is not less than the target retraction time, the auxiliary reset device of the stop block is activated to shorten the actual retraction time of the stop block.

[0092] In this embodiment, the system first compares the actual retraction time measured by a high-precision sensor with the target retraction time calculated based on the conveying efficiency of the feeder. When the actual retraction time is greater than or equal to the target retraction time, the system determines that the retraction speed of the stop block does not meet production requirements and may affect the feeding time of the next LCD panel. At this time, the control system immediately sends a start command to the auxiliary reset device. The auxiliary reset device can be an additional cylinder, motor, or other mechanical auxiliary mechanism that can provide additional thrust or pull force to accelerate the retraction process of the stop block. The activation of the auxiliary reset device is gradual. The system dynamically adjusts the magnitude of the auxiliary force according to the difference between the actual retraction time and the target retraction time to avoid impact or vibration caused by excessively fast movement of the stop block due to excessive auxiliary force. By activating the auxiliary reset device, the retraction speed of the stop block is increased, and the actual retraction time is shortened accordingly, thereby ensuring that it can complete the retraction action within the target time.
