Abstract
Description
Technical Field
[0001] This utility model relates to the field of control cabinet technology, and in particular to an engineering touch screen control cabinet and a vehicle manufacturing production line. Background Technology
[0002] As competition in the automotive industry intensifies, vehicle models are improved annually, necessitating upgrades to manufacturing equipment to meet evolving process requirements. In automotive manufacturing, the level of automation across various processes is constantly increasing, leading to a rise in the number of safety switch components such as light barriers, safety doors, and emergency stop buttons.
[0003] Currently, most of these safety switch components use normally closed double terminals, with both terminals connected to a safety relay. The safety relay then converts the signal to the PLC control unit for control. This method of simultaneous double-terminal wiring achieves a safe redundancy design, ensuring the effectiveness of the safety components. However, this solution requires a corresponding safety relay for each safety switch component. The use of a large number of safety relays occupies a significant amount of control cabinet space, making subsequent expansion of the control cabinet's functionality difficult.
[0004] Therefore, it is necessary to provide a new engineering touch screen control cabinet and vehicle manufacturing production line to solve the above-mentioned technical problems. Utility Model Content
[0005] The main purpose of this utility model is to propose an engineering touch screen control cabinet and a vehicle manufacturing production line, aiming to improve the technical problem of difficulty in expanding the function of the control cabinet in the prior art.

The safety PLC input module and the safety PLC output module are respectively signal-connected to the safety switch control component. The safety PLC input module is used to connect to the safety switch element, and the safety PLC output module is used to connect to the actuator element.
[0011] In one embodiment, there are multiple safety PLC input modules and multiple safety PLC output modules. The multiple safety PLC input modules are used to connect to different safety switch elements, and the multiple safety PLC output modules are used to connect to different actuators.
[0012] In one embodiment, each of the safety PLC input modules includes at least two input channels, one end of each input channel is used to connect to the same safety switch element, and the other end of each input channel is signal-connected to the safety switch control component.
[0013] In one embodiment, the safety switch control component includes a redundancy processing unit and a difference detection unit. The redundancy processing unit is connected to the two input channels respectively, and the difference detection unit is connected to the redundancy processing unit and the safety PLC output module respectively. The redundancy processing unit is used to compare the input signals of the two input channels in real time. When the difference between the input signals of the two input channels exceeds a preset threshold, the difference detection unit is used to force the actuator to stop through the safety PLC output module.
[0014] In one embodiment, the safety switch control assembly further includes a redundant control loop. Each safety PLC output module includes a main output channel and at least one secondary output channel. The redundant control loop is used to connect the main output channel to the actuator or to connect the secondary output channel to the actuator. The redundant control loop is also used to detect whether the main output channel is faulty. When the main output channel is faulty, the redundant control loop is used to connect the secondary output channel to the actuator.
[0015] In one embodiment, the safety PLC further includes a central processing unit (CPU), which is signal-connected to the safety switch control component and is used to record events processed by the safety switch control component.
[0016] According to another aspect of the present invention, the present invention also provides a vehicle manufacturing production line, including an actuator, a safety switch element, and the aforementioned engineering touch screen control cabinet, wherein the actuator is connected to the engineering touch screen control cabinet, and the safety switch element is connected to the engineering touch screen control cabinet via an aviation connector.
[0017] In one embodiment, there are multiple actuators, multiple safety switch elements, and multiple engineering touch screen control cabinets. The multiple actuators are connected to the multiple engineering touch screen control cabinets in a one-to-one correspondence, and each safety switch element is connected to two engineering touch screen control cabinets via an aviation plug.
[0018] In one embodiment, the vehicle manufacturing production line includes an actuator interlock box and a safety switch interlock box. The input terminal of the actuator interlock box is connected to a plurality of the safety switch elements, the output terminal of the actuator interlock box is connected to the input module of the safety PLC, the output terminal of the safety switch interlock box is connected to the input module and the output module of the safety PLC, respectively, and the input terminal of the safety switch interlock box is connected to a plurality of the actuator elements.
[0019] In one embodiment, both the safety opening interlock box and the actuator interlock box are connected to the engineering touch screen control cabinet via aviation connectors.
[0020] In the above scheme, the engineering touch screen control cabinet includes a cabinet body, a cabinet door, a control PLC, and a safety PLC. The cabinet body forms a receiving cavity, and the cabinet door is rotatably installed on the cabinet body. The cabinet door is used to cover or open the receiving cavity. Both the safety PLC and the control PLC are installed in the cabinet body and are placed in the receiving cavity. The control PLC is used to connect to the actuator and is signal-connected to the safety PLC. The safety PLC includes a safety switch control component, a safety PLC input module, and a safety PLC output module. The safety PLC input module and the safety PLC output module are respectively signal-connected to the safety switch control component. The safety PLC input module is used to connect to the safety switch element, and the safety PLC output module is used to connect to the actuator. Specifically, the engineering touch screen control cabinet includes a cabinet body and a cabinet door. The cabinet body has a receiving cavity in which the control PLC and safety PLC are installed side by side. The safety PLC input module connects to multiple safety switch elements through a standardized interface. The safety switch elements can be emergency stop buttons, safety light curtains, and safety door locks, etc. The normally closed contact of each safety element is directly connected to the independent port of the safety PLC input module.

The actuators can be servo drives, pneumatic valve groups, and robots, etc. The safety switch control component uses a safety-type processor with a built-in safety logic operation unit that conforms to international standards, such as IEC 61131-3. When the safety switch element is triggered, its normally closed contact opens. The safety PLC input module collects the status changes of the safety switch element in real time and transmits the current status to the safety switch control component. The safety switch control component periodically scans the input signal and determines whether it is a valid fault signal through a preset safety algorithm. If a valid fault is determined, the safety switch control component immediately cuts off the power supply to the actuator through the safety PLC output module, thereby stopping or reducing the speed of the actuator. At the same time, the safety PLC sends a safety status code to the control PLC via the industrial Ethernet protocol. The control PLC decodes the code and adjusts the production line operating mode according to the safety status code. This utility model integrates the safety relay function into the safety PLC. A single safety PLC has multiple safety PLC input modules and multiple safety PLC output modules. One safety PLC can replace multiple independent safety relays, thereby reducing the space occupied inside the control cabinet. Furthermore, if it is necessary to add more safety switch elements in the future, the safety PLC input module can be modularly expanded by increasing the number of bus interfaces. The newly added safety switch elements only require software configuration and do not require hardware modification. Attached Figure Description

[0031] To achieve the above objectives, according to one aspect of this utility model, please refer to... Figure 1This utility model proposes an engineering touch screen control cabinet 100, which includes a cabinet body 1, a cabinet door 2, a control PLC and a safety PLC. The cabinet body 1 forms a receiving cavity 11. The cabinet door 2 is rotatably installed on the cabinet body 1 and is used to cover or open the receiving cavity 11. The safety PLC and the control PLC are both installed on the cabinet body 1 and are both placed in the receiving cavity 11. The control PLC is used to connect to the actuator 102 and is signal-connected to the safety PLC. The safety PLC includes a safety switch control component 41, a safety PLC input module 42 and a safety PLC output module 43. The safety PLC input module 42 and the safety PLC output module 43 are respectively signal-connected to the safety switch control component 41. The safety PLC input module 42 is used to connect to the safety switch element 101, and the safety PLC output module 43 is used to connect to the actuator 102. Specifically, the engineering touch screen control cabinet 100 includes a cabinet body 1 and a cabinet door 2. The cabinet body 1 has a receiving cavity 11. The control PLC and the safety PLC are installed side by side in the receiving cavity 11. The safety PLC input module 42 of the safety PLC is connected to multiple safety switch elements 101 through a standardized interface. The safety switch elements 101 can be emergency stop buttons, safety light curtains, and safety door locks, etc. The normally closed contact of each safety element is directly connected to the independent port of the safety PLC input module 42. The safety PLC output module 43 is connected to the actuator 102 through hard wiring. The actuator 102 can be a servo driver, pneumatic valve group, and robot, etc. The safety switch control component 41 adopts a safety-type processor and has a built-in safety logic operation unit that conforms to international standards, such as IEC 61131-3. When safety switch element 101 is triggered, its normally closed contact opens. The safety PLC input module 42 collects the status changes of safety switch element 101 in real time and transmits the current status to the safety switch control component 41. The safety switch control component 41 periodically scans the input signal and determines whether it is a valid fault signal through a preset safety algorithm. If it is determined to be a valid fault, the safety switch control component 41 immediately cuts off the power supply to the actuator 102 through the safety PLC output module 43, so as to stop or reduce the speed of the actuator 102. At the same time, the safety PLC sends a safety status code to the control PLC through the industrial Ethernet protocol. The control PLC decodes the code and adjusts the production line operation mode according to the safety status code. This utility model integrates the function of safety relays into a safety PLC. A single safety PLC has multiple safety PLC input modules 42 and multiple safety PLC output modules 43. One safety PLC can replace multiple independent safety relays, thereby reducing the space occupied inside the control cabinet. At the same time, if it is necessary to add safety switch elements 101 in the future, the safety PLC input modules 42 can be modularly expanded by increasing the number of bus interfaces. The newly added safety switch elements 101 only require software configuration and do not require hardware modification.
[0032] Please see Figure 1 In one embodiment, there are multiple safety PLC input modules 42 and multiple safety PLC output modules 43. The multiple safety PLC input modules 42 are used to connect to different safety switch elements 101, and the multiple safety PLC output modules 43 are used to connect to different actuators 102. Multiple safety PLC input modules 42 and multiple safety PLC output modules 43 can support the connection of more types and numbers of safety switch elements 101 and actuators 102. Without changing the original structure, the system functions can be flexibly expanded by increasing the number of modules or replacing them with high-density modules to meet the complex control needs of different production lines or equipment. Each safety PLC input module 42 can be dedicated to a specific type of safety switch element 101; for example, one module may be responsible for emergency stop signals, and another for safety door status. Each safety PLC output module 43 can also correspond to a specific actuator 102. This modular division of labor makes the system logic clearer, the wiring simpler, and improves the maintainability and diagnosability of the system.
[0033] Please see Figure 1 and Figure 3 In one embodiment, each safety PLC input module 42 includes at least two input channels 421. One end of each input channel 421 is connected to the same safety switch element 101, and the other end of each input channel 421 is connected to the safety switch control component 41 for signal transmission. The safety PLC input module 42 includes two independent input channels 421. Taking an emergency stop button as an example, the two terminals of the normally closed contact of the emergency stop button are respectively connected to the two input channels 421. When the emergency stop button is triggered, its two contacts open synchronously. When both input channels 421 simultaneously detect a low-level signal, the safety switch control component 41 receives the signal and then cuts off the power supply to the corresponding actuator 102 through the safety PLC output module 43. Thus, even if one input channel 421 malfunctions and cannot detect a low-level signal, the other input channel 421 can still transmit the low-level signal to the safety switch control component 41 to cut off the power supply to the corresponding actuator 102. By using dual input channels 421 to monitor the state of the same safety switch element 101, the reliability of the system's detection of critical safety signals can be significantly improved. If one input channel 421 malfunctions or misreads, the other channel can still accurately report the status of the safety switch element 101. This structure provides a redundancy mechanism, and redundancy design is one of the important means to ensure system stability and safety. When one channel detects an anomaly, the system can make a more accurate judgment based on the data from the other channel.
[0034] Please see Figure 1 and Figure 3In one embodiment, the safety switch control component 41 includes a redundancy processing unit 411 and a difference detection unit 412. The redundancy processing unit 411 is connected to two input channels 421 respectively, and the difference detection unit 412 is connected to the redundancy processing unit 411 and the safety PLC output module 43 respectively. The redundancy processing unit 411 is used to compare the input signals of the two input channels 421 in real time. When the difference between the input signals of the two input channels 421 exceeds a preset threshold, the difference detection unit 412 is used to force the execution element 102 to stop through the safety PLC output module 43. The safety switch control component 41 integrates the redundancy processing unit 411 and the difference detection unit 412. The redundancy processing unit 411 collects the signals of the two input channels 421. The redundancy processing unit 411 can be a dual-core processor. The dual-core processor independently collects the signals of the two input channels 421. The difference detection unit 412 receives the signals of the two input channels 421 and then compares the two signals. When the difference between the two signals exceeds the preset difference threshold of the difference detection unit 412, the difference detection unit 412 immediately forces the execution element 102 to stop. By employing dual-channel input for the same safety signal and comparing it in real time using a redundant processing unit 411, misjudgments caused by misreading of a single channel, noise interference, or line faults can be effectively avoided. Only when the signals from the two input channels 421 are consistent is the system considered to be in a normal state, thus significantly improving the accuracy of the system's identification of critical safety signals. When the difference exceeds a set threshold, the system does not wait for manual intervention or further confirmation, but directly triggers the safety PLC output module 43 through the difference detection unit 412, forcing the execution element 102 to stop. This structure ensures that even in the event of a fault within the control system, the safety of personnel and equipment can be maximized.
[0035] Please see Figure 1 and Figure 3In one embodiment, the safety switch control assembly 41 further includes a redundant control loop 413. Each safety PLC output module 43 includes a main output channel 431 and at least one secondary output channel 432. The redundant control loop 413 is used to connect the main output channel 431 to the actuator 102 or to connect the secondary output channel 432 to the actuator 102. The redundant control loop 413 is also used to detect whether the main output channel 431 is faulty. When the main output channel 431 is faulty, the redundant control loop 413 connects the secondary output channel 432 to the actuator 102. The safety PLC output module 43 includes a main output channel 431 and a secondary output channel 432. The redundant control loop 413 is composed of a solid-state relay 413a and a fault detection circuit 413b. Both the main output channel 431 and the secondary output channel 432 are connected to the actuator 102 through the solid-state relay 413a. The fault detection circuit 413b monitors the output current and voltage of the main output channel 431 in real time. During normal operation, when the fault detection circuit 413b detects that the voltage or current of the main output channel 431 is normal, meaning there is no fault in the main output channel 431, the main output channel 431 controls the actuator 102 to stop operating through the redundant control loop 413. When a fault occurs in the main output channel 431, the fault detection circuit 413b detects that the voltage or current of the main output channel 431 is abnormal, and the secondary output channel 432 controls the actuator 102 to stop operating through the solid-state relay 413a. By setting a main output channel 431 and at least one secondary output channel 432, when a fault occurs in the main output channel 431, the redundant control loop 413 can automatically switch to the secondary output channel 432, ensuring that the actuator 102 can continue to operate normally and avoiding system downtime or safety accidents caused by a single output channel failure.
[0036] In one embodiment, the safety PLC further includes a central processing unit (CPU), which is signal-connected to the safety switch control component 41. The CPU records events processed by the safety switch control component 41. By recording various events during system operation, including normal operations and abnormal situations, maintenance personnel can quickly and accurately locate and analyze the causes of faults based on this log information when a failure occurs, greatly improving the efficiency of fault diagnosis. Detailed log records facilitate the retrospective tracing of specific events or accidents, which is very useful for understanding the cause, process, and result of an event. Furthermore, when safety audits or compliance checks are required, these records can serve as evidence that the system's operation complies with relevant standards and regulations.
[0037] According to another aspect of this utility model, please refer to Figure 1 and Figure 2This utility model also provides a vehicle manufacturing production line, including an actuator 102, a safety switch element 101, and the aforementioned engineering touch screen control cabinet 100. The actuator 102 is connected to the engineering touch screen control cabinet 100, and the safety switch element 101 is connected to the engineering touch screen control cabinet 100 via aviation connectors. By using aviation connectors to achieve rapid connection between components, the entire system possesses a high degree of modularity. Aviation connectors support plug-and-play operation, eliminating the need for complex wiring processes and significantly shortening equipment installation and commissioning time. Since the vehicle manufacturing production line includes all embodiments of the aforementioned engineering touch screen control cabinet 100, it possesses at least all the beneficial effects brought by all the aforementioned embodiments, which will not be elaborated further here.
[0038] Please see Figure 1 and Figure 2 In one embodiment, there are multiple actuators 102, multiple safety switch elements 101, and multiple engineering touch screen control cabinets 100. Each actuator 102 is connected to one of the multiple engineering touch screen control cabinets 100 in a one-to-one correspondence. Each safety switch element 101 is connected to two engineering touch screen control cabinets 100 via an aviation connector. When a safety switch element 101 is triggered, both the preceding and following manufacturing processes are stopped, achieving safety interlock control.
[0039] Please see Figure 1 and Figure 2 In one embodiment, the vehicle manufacturing production line includes an actuator interlock box 202 and a safety switch interlock box 201. The input terminal of the actuator interlock box 202 is connected to multiple safety switch elements 101, and the output terminal of the actuator interlock box 202 is connected to a safety PLC input module 42. The output terminal of the safety switch interlock box 201 is connected to both the safety PLC input module 42 and the safety PLC output module 43, respectively. The input terminal of the safety switch interlock box 201 is connected to multiple actuator elements 102. The safety switch interlock box 201 centrally processes the signals from multiple dispersed safety switch elements 101 and uniformly connects them to the safety PLC input module 42 of the safety PLC. The actuator interlock box 202 centrally controls the multiple actuator elements 102, making the system structure clearer, the wiring simpler, and improving the overall integration level.
[0040] In one embodiment, both the safety switch interlock box 201 and the actuator interlock box 202 are connected to the engineering touch screen control cabinet 100 via aviation connectors. Aviation connectors typically possess excellent electrical performance, mechanical strength, and environmental adaptability, effectively resisting the effects of adverse factors such as vibration, dust, and moisture, ensuring the stability and reliability of signal transmission. Aviation connectors support quick plug-and-play operations, greatly simplifying the connection process between the safety switch interlock box 201 and the actuator interlock box 202 and the engineering touch screen control cabinet 100, making installation more convenient and efficient. When equipment maintenance or replacement is required, it can be quickly disconnected and reconnected, reducing downtime and improving work efficiency.
