Description

Technical Field

[0001] This application relates to the field of control system technology for machining platforms, and in particular to a general platform control system. Background Technology

[0002] With the continuous development of modern industry, the demand for industrial automation and intelligent production is increasing, especially in the automotive parts manufacturing sector, which places higher demands on the flexibility, versatility, and operability of equipment. Automotive parts manufacturers typically need to frequently switch between producing different models and specifications of products, such as sealing strips of various sizes and shapes, based on market demand. Control systems need to be able to quickly adapt to product changes, adjust production processes and parameters, and achieve efficient mass production.

[0003] Relevant prior art, such as the Chinese patent application "Training Platform for Motor Control System" (application number CN201820249031.4), discloses a training platform comprising: a PLC control system for sending control commands; a frequency converter and a motor controller, which are respectively connected to the PLC control system for controlling the operation of the motor according to the control commands issued by the PLC control system. The technical solution provided by this utility model helps improve operators' practical operational and maintenance capabilities for motor control systems.

[0004] Traditional control systems are typically designed for specific equipment or processes, making it difficult to adapt to production switchovers involving multiple products and processes. For example, a motor control system training platform is primarily used for training in the operation and maintenance of motor control systems and cannot be directly used to control other production equipment. In automotive parts manufacturing, different products may require different production processes and equipment control logics, and traditional control systems struggle to adapt quickly to these changes, resulting in low production switchover efficiency.

[0005] Existing control systems have limited capabilities in detecting and protecting against dangerous actions. In motor control systems, if a malfunction occurs during operation, operators may not be able to obtain fault information and take timely measures, potentially leading to equipment damage or even endangering personnel safety. In automotive parts manufacturing, efficient equipment operation and personnel safety are paramount, and the inadequate safety protection of traditional control systems poses a significant hidden danger in production. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a universal platform control system. The control system is compatible with general systems and can be switched between different products and controlled by operators through simple operation. It adds safety protection detection to detect dangerous actions of personnel and machines, thereby improving the safety of the equipment.

[0007] The technical solution adopted in this application is: a general-purpose platform control system, comprising:

[0008] The controller integrates power control circuitry and is used to receive, process, and transmit signals, as well as control the corresponding actions of the power cylinders on the production workstation group.

[0009] The human-machine interface is electrically connected to the controller. Operators can interact with the controller through the human-machine interface and preset the controller parameters through the human-machine interface.

[0010] The production workstation group is equipped with sensors connected to the controller, and the controller receives the sensing signals of the product placement detected by the sensors.

[0011] Safety protection detection sensors are installed on the equipment and electrically connected to the controller to detect dangerous actions of personnel in real time and send detection signals to the controller.

[0012] Compared with existing technologies, the advantages of this application are as follows: First, the human-machine interface (HMI) is electrically connected to the controller, allowing operators to interact with the controller and preset controller parameters. This efficient information interaction enables operators to obtain equipment operating status promptly and accurately, improving operational convenience and production efficiency. Operators can preset controller parameters through the HMI according to production needs, meeting different production processes and product requirements, thus enhancing the system's versatility and adaptability. By quickly adapting to product changes and automated control, the system can achieve efficient mass production, meet market demands, and improve the company's production efficiency.

[0013] Secondly, sensors are installed at each production station and connected to the controller. These sensors detect the placement of products and transmit the signals to the controller, enabling automated control and real-time monitoring of the production process, thereby improving production efficiency and product quality stability. The controller executes corresponding actions based on the sensor signals, optimizing the production process and enhancing both efficiency and product quality.

[0014] Finally, sensors are deployed on the equipment and electrically connected to the controller to detect dangerous actions by personnel in real time and send signals to the controller, enabling the equipment to respond quickly when danger is detected, such as stopping operation in time, effectively ensuring the safety of personnel and equipment, reducing the risk of production safety accidents, and meeting modern industrial production safety standards.

[0015] In some embodiments of this application, the human-machine interface (HMI) employs a touchscreen display. The HMI reads and displays equipment status, alarms, and controls equipment actions via a controller. The touchscreen display presents equipment status with intuitive graphics and text information, enabling operators to quickly understand the equipment's operating status. Real-time reading and display of equipment status and alarms allows operators to promptly detect anomalies and respond, reducing equipment downtime and production losses. Centralized control of equipment actions via the touchscreen simplifies the operation process and improves production efficiency.

[0016] Specifically, the equipment status can be defined as the equipment's operating parameters.

[0017] For example, the motor status display shows real-time parameters such as motor speed, current, voltage, and power, as well as cumulative data such as motor running time and number of starts and stops. This helps operators understand the motor's workload and efficiency, and promptly detect whether the motor is overloaded or operating abnormally.

[0018] Cylinder status: This includes the cylinder's extended and retracted positions, air pressure, and number of cycles. Monitoring the cylinder status ensures its normal operation and prevents production interruptions due to insufficient air pressure or cylinder malfunction.

[0019] Production station status: This includes sensor signals, cylinder operation status, and production progress at each production station. Operators can easily understand the working status of each station, facilitating timely adjustments to production plans and handling of abnormal stations.

[0020] Specifically, the device status can be the state of the device.

[0021] For example: Start / Stop Status: Clearly displays whether the device is currently in a start or stop state, making it convenient for operators to operate and confirm.

[0022] Fault Status: When the equipment malfunctions, the human-machine interface will display specific fault information, such as fault code, fault location, and fault cause, to help maintenance personnel quickly locate and resolve the problem.

[0023] Emergency Stop Status: When the emergency stop button is pressed, the display shows that the device is in emergency stop status, reminding the operator to pay attention to safety and deal with the abnormal situation in a timely manner.

[0024] Safety protection detection sensor status: Displays whether the safety protection detection sensors are working properly and whether they have detected any dangerous actions by personnel or machines. This includes the status of sensors such as safety light curtains and safety door locks, ensuring the personal safety of operators and the safe operation of equipment.

[0025] In some embodiments of this application, the production workstation group includes an upper operating table and a lower operating table, each with at least two production workstations. Multiple production workstations operating simultaneously increase production capacity per unit time, meeting the demands of large-scale production. This facilitates the arrangement of different production tasks or processes, enabling parallel processing of the production flow and shortening the production cycle. Multiple workstations sharing equipment resources improves the overall utilization rate of the equipment and reduces production costs.

[0026] In some embodiments of this application, each production station is equipped with a corresponding power cylinder, which completes the processing steps. The power cylinder provides a stable power output to the production station, ensuring the accuracy and consistency of the processing steps and improving product quality. Appropriate power cylinder types and specifications can be selected according to different production needs to achieve various processing techniques and meet the production requirements of different products. The power cylinder automatically completes the processing steps, reducing manual intervention and improving the automation level and production efficiency of the production process.

[0027] In some embodiments of this application, the power cylinder is connected to a controller. The power cylinder is a motor and / or a pneumatic cylinder. The controller reads the real-time speed, current, and voltage of the motor, and the position, air pressure, and number of strokes of the cylinder's output rod. The controller reads key operating parameters of the power cylinder in real time, providing data support for equipment status monitoring and fault diagnosis, enabling timely detection of potential faults and maintenance. Based on real-time data, the controller can precisely control the operation of the power cylinder, achieving optimized adjustments to the processing process and improving production efficiency and product quality.

[0028] In some embodiments of this application, the application also includes a lifting motor, which is connected to the upper operating platform and the lower operating platform, and is electrically connected to the controller. The lifting motor drives the upper operating platform or the lower operating platform to move to the platform of the equipment.

[0029] Typically, different operating platforms are equipped with production stations for different processes. Operators can flexibly select operating platforms according to production needs, enabling rapid switching between different processes and improving the versatility and adaptability of the equipment. This facilitates the arrangement of production sequences and process flows, reduces production waiting time and material handling, and improves production efficiency. It also makes full use of equipment resources, enabling multi-process production and reducing equipment idleness and redundant investment.

[0030] In some embodiments of this application, the device is provided with an upper limit member and a lower limit member, which limit the position limits of the upper and lower operating platforms under the drive of the lifting motor.

[0031] Upper and lower limit switches effectively prevent the operating platform from exceeding its limits, avoiding equipment damage and production accidents, and extending equipment lifespan. They ensure equipment operates within safe limits, improving the stability and reliability of the production process. They also reduce equipment failures and maintenance workload caused by excessive movement, saving maintenance costs.

[0032] In some embodiments of this application, an operation button is also included. The operation button is connected to the controller, and pressing the operation button controls the start-up, normal shutdown, and emergency stop of the equipment. This provides an intuitive and convenient method for controlling equipment start-up, shutdown, and emergency stop, facilitating quick response by operators to production needs and abnormal situations. The emergency stop button can quickly cut off the power supply to the equipment in dangerous situations, ensuring the safety of personnel and equipment.

[0033] In some embodiments of this application, the security protection detection sensor includes a transmitter and a receiver disposed on the device, wherein the transmitter emits infrared light and the receiver receives the infrared light emitted by the transmitter.

[0034] When a person or object enters the detection area, it blocks the infrared light emitted by the transmitter. The receiver immediately detects this and sends a signal, triggering the equipment to stop operating and preventing personnel from colliding with the machine or getting caught in dangerous areas.

[0035] In some embodiments of this application, the safety protection detection sensor includes a safety protection door installed on the device, and the safety protection door is connected to the controller.

[0036] The equipment can only operate normally when the safety door lock is closed and locked. When the safety door is opened, the safety door lock detects the signal change, and the equipment immediately stops operating to prevent personnel from opening the door during equipment operation and causing danger.

[0037] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

Controller 1 executes corresponding actions based on the sensing signals, optimizing the production process and enhancing both production efficiency and product quality.

[0047] Safety protection detection sensor 3 is installed on the equipment and electrically connected to controller 1. It detects dangerous actions by personnel in real time and sends detection signals to controller 1. This enables the equipment to respond quickly when danger is detected, such as stopping operation in time, effectively ensuring the safety of personnel and equipment, reducing the risk of production safety accidents, and meeting modern industrial production safety standards.

[0048] The human-machine interface 2 (HMI 2) uses a touchscreen display. HMI 2 reads and displays equipment status, alarms, and controls equipment actions via controller 1. The touchscreen display presents equipment status with intuitive graphics and text information, allowing operators to quickly understand the equipment's operating status. Real-time reading and display of equipment status and alarms enable operators to promptly detect anomalies and respond, reducing equipment downtime and production losses. Centralized control of equipment actions via the touchscreen simplifies the operation process and improves production efficiency.

[0049] Specifically, the equipment status can be defined as the equipment's operating parameters.

[0050] For example, the motor status display shows real-time parameters such as motor speed, current, voltage, and power, as well as cumulative data such as motor running time and number of starts and stops. This helps operators understand the motor's workload and efficiency, and promptly detect whether the motor is overloaded or operating abnormally.

This includes the status of sensors such as safety light curtains and safety door locks, ensuring the personal safety of operators and the safe operation of equipment.

[0058] Example 2, as Figures 1 to 2 As shown, the production station group 4 includes an upper operating table and a lower operating table, each with at least two production stations. Multiple production stations operate simultaneously, increasing production capacity per unit time and meeting the needs of large-scale production. This facilitates the arrangement of different production tasks or processes, enabling parallel processing of the production flow and shortening the production cycle. Multiple stations share equipment resources, improving the overall utilization rate of the equipment and reducing production costs.

[0059] Each production station is equipped with a corresponding power cylinder 8, which completes the processing steps. The power cylinder 8 provides a stable power output to the production station, ensuring the accuracy and consistency of the processing steps and improving product quality. Appropriate types and specifications of power cylinders 8 can be selected according to different production needs to achieve various processing techniques and meet the production requirements of different products. The power cylinder 8 automatically completes the processing steps, reducing manual intervention and improving the automation level and production efficiency of the production process.

[0060] The power cylinder 8 is connected to the controller 1. The power cylinder 8 is a motor and / or a pneumatic cylinder. The controller 1 reads the real-time speed, current, and voltage of the motor, and the position, air pressure, and number of strokes of the cylinder's output rod.

[0061] This application also includes a lifting motor 6, which is connected to the upper and lower operating platforms and electrically connected to the controller 1. The lifting motor 6 drives the upper or lower operating platform to move to the equipment's platform. Generally, different operating platforms are used to set up production stations for different processes. Operators can flexibly select operating platforms according to production needs, enabling rapid switching between different processes and improving the equipment's versatility and adaptability. This facilitates the arrangement of production sequences and processes, reduces production waiting time and material handling, and improves production efficiency. It also fully utilizes equipment resources, enabling multi-process production and reducing equipment idleness and redundant investment.

[0062] The equipment is equipped with upper and lower limit switches, which restrict the maximum movement of the upper and lower operating platforms under the drive of the lifting motor 6. These upper and lower limit switches effectively prevent the operating platforms from exceeding their limits, avoiding equipment damage and production accidents, and extending the equipment's service life. They ensure the equipment operates within a safe range, improving the stability and reliability of the production process. They also reduce equipment failures and maintenance workload caused by excessive movement, saving maintenance costs.

[0064] The safety protection detection sensor 3 includes a transmitter and a receiver installed on the equipment. The transmitter emits infrared light, and the receiver receives the infrared light emitted by the transmitter. When a person or object enters the detection area, it blocks the infrared light emitted by the transmitter. The receiver immediately detects this and sends a signal, triggering the equipment to stop operating and preventing personnel from colliding with the machine or being drawn into dangerous areas.
