Description
Technical Field
[0001] The present application relates to the technical field of automobile seat detection, and in particular to a detection device and a detection method for active side wings of an automobile seat. Background Art
[0002] When the driver drives at high speed through a curve, the driver's body will be relatively offset on the seat due to centrifugal force. At this time, the active side wing system on the car seat can automatically receive the cornering signal and quickly provide the driver with support to counteract the centrifugal force, so that the human torso remains in the middle of the seat. In this scenario, the intelligent system can not only improve driving comfort and stability, but also ensure that the driver's field of vision is not affected, ensure the effectiveness of the passive safety system on the car, and thus improve driving safety.
[0003] Car seats are generally assembled and produced on an assembly line. After assembly and before packaging and shipment, the electrical functions of the seats need to be checked.
[0004] Since the active wing system contains many components and the connections between the components are also complicated, problems are easy to occur during the assembly process. In the existing technology, the active wing system of the seat can only be made to work by driving the vehicle vigorously. It is almost impossible to test the function of the active wing system during the production process of the seat in this way. At the same time, the testing equipment needs to be used in conjunction with the seat production line, and the time left for the testing equipment is very tight. In addition, since the daily output is fixed, seats with problems in the active wing system also appear randomly, so the seats must be 100% tested, and seats with known faults in the active wing system must also be 100% identified.

In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0048] The embodiment of the present application provides an active wing detection device for a car seat, comprising a detection station arranged on an assembly line, a detection component arranged at the detection station, and a control processing device for controlling the detection component. The following drawings describe the embodiment of the present application in detail. Figure 1 It is a schematic diagram of the structure of an active side wing detection device for a car seat shown in an embodiment of the present application.
[0049] Specifically, the inspection station is a frame structure, which is used to install the inspection components and control processing devices, and provide structural support for the inspection components and control processing devices. One inspection station can install two sets of inspection components and control processing devices, and can inspect two seats to be inspected at the same time. The specific structure of the automotive seat active side wing inspection equipment after installation is referenced Figure 2 shown. Figure 2 It is a schematic diagram of an active side wing detection device for a car seat in an actual scenario shown in an embodiment of the present application.
[0050] The detection station is configured to start the detection component based on a start instruction generated by a seat barcode of the seat to be detected when it is determined that the seat to be detected reaches the target detection position. The seat barcode at least represents the seat type of the seat to be detected.
[0051] Among them, the seat barcode is also used to represent the batch number of the seat to be tested. After scanning the barcode, the batch number and seat type of the seat to be tested will be uploaded to the control processing device for record preservation, which is convenient for staff to search or trace.
[0052] The detection component is configured to execute a detection process corresponding to the active wing of the seat to be detected based on the start instruction to perform a functional detection on the active wing of the seat to be detected.
[0053] Specifically, since the inspection standards and inspection methods for different seats are different, after the control processing device obtains the information contained in the seat barcode, it configures a targeted inspection process for the seat to be inspected according to the information obtained, and generates a start instruction. The generated start instruction contains the corresponding inspection process. After the generation is completed, the start instruction is sent to the inspection component. The inspection component starts the inspection according to the start instruction, and inspects the seat to be inspected according to the inspection process contained in the start instruction, so as to achieve comprehensive inspection of different types of seats.
[0054] The storage space of the control processing device stores detection processes corresponding to different types of active winglets.
[0055] This embodiment provides an active wing detection device for automobile seats, which can be connected to the seats to be detected on the assembly line. After obtaining the information of the seats to be detected, it can generate a dedicated detection process according to different seat types, thereby realizing the detection of the seats to be detected on the assembly line, solving the inconvenience caused by the need to complete the detection under intense driving conditions. At the same time, by setting up dedicated detection processes for different types of seats, the active wing of the automobile seat can be fully functionally verified and quality inspected, and potential problems can be discovered and resolved in a timely manner to prevent unqualified products from entering the market. This not only improves the reliability of the product, but also enhances the driving experience and safety of customers. In addition, the automated and intelligent testing process reduces manual operations, improves production efficiency, and reduces production costs.
[0056] In the embodiment of the present application, the vehicle seat active side wing detection device includes a detection component, and the specific structure is referenced Figure 1 As shown, including:
[0057] The barcode scanner 1 is electrically connected to the control processing device and is used to scan the barcode on the seat to be detected, and send the seat type obtained after scanning to the control processing device so that the control processing device generates a start instruction.
[0058] Specifically, the barcode scanner 1 obtains the seat information of the seat to be detected by scanning the barcode on the seat to be detected. The seat information of the seat to be detected includes the seat type and batch number. After the seat information is obtained, it is sent to the control processing device. The control processing device generates a special start-up instruction for the seat to be detected based on the received seat information.
[0059] The start-up instruction includes the inspection process of the seat to be inspected and the data to be collected.
[0060] PLC2 is electrically connected to the control processing device, and is used for receiving a start instruction generated by the control processing device, detecting the active side wing of the seat to be detected according to the detection process corresponding to the start instruction, and sending the detection data obtained after the detection to the control processing device.
[0061] Among them, PLC2 collects the data generated by various functions during the detection process according to the data that needs to be collected in the startup instruction, so as to obtain the detection data. During the collection process, it is necessary to control the current sensor 4 and the laser ranging sensor 5 to collect current data and displacement data respectively, and send them to PLC2 after the collection is completed. Since the collected current data and displacement data are voltage signals, the collected voltage signals are converted into digital signals through PLC2, and the obtained digital signals are the detection data.
[0062] The current sensor 4 is electrically connected to the PLC2 and is used to collect the current data generated by the inflation and deflation of the airbag of the active wing of the seat to be inspected during the inspection process, and send the current data to the PLC2.
[0063] The laser distance measuring sensor 5 is electrically connected to the PLC2 and is used to collect displacement data generated by the inflation and deflation of the airbag of the active wing of the seat to be inspected during the inspection process, and send the displacement data to the PLC2.
[0064] Among them, the detection component also includes a DC power supply 6, which is electrically connected to the power supply unit of the seat to be detected, and is used to supply power to the seat to be detected after the detection is started, simulating the power supply state of the seat after the vehicle is started in a real scene.
[0065] In this embodiment, the detection component has a built-in high-precision sensor and is controlled by PLC2. During the detection process, it can monitor in real time various parameters of the active side wings of the car seat in the detection process and complete a comprehensive test of the active side wings of the car seat.
[0066] In the embodiment of the present application, the vehicle seat active side wing detection device further includes a control processing device, and the specific structure is referred to Figure 1 As shown, including:
[0067] The industrial computer 7 is electrically connected to the barcode scanner 1 and the PLC2, respectively, and is used for generating a start instruction corresponding to the seat type after receiving the seat type sent by the barcode scanner 1, and sending the start instruction to the PLC2, so that the PLC2 controls the detection component to detect the active side wing of the seat to be detected based on the detection process corresponding to the seat type, and is used for receiving the detection data sent by the PLC2 and the feedback information of the seat to be detected during the detection process.
[0068] Among them, PLC2 is provided with a PROFINET (PROFIBUS International, PI) Ethernet interface, which can be connected to the network port of the industrial computer 7 through a network cable. The industrial computer 7 reads the real-time data of the current sensor 4 and the laser ranging sensor 5 collected by PLC2 through the S7 (Siemens) protocol.
[0069] The detection data is detection data of various functions, and the industrial computer 7 generates detection results of various functions according to the detection data.
[0070] Furthermore, the industrial computer 7 is also connected to the seat to be tested via the CAN bus 3, and is used to send vehicle driving simulation condition data to the seat to be tested, so as to simulate the active side wing operation state of the seat to be tested in a real driving environment. During the simulation process, the seat to be tested will feed back feedback information to the industrial computer 7 via the CAN bus 3, and the industrial computer 7 determines whether the seat to be tested is operating normally based on the feedback information.
[0071] Among them, the feedback information is the airbag pressure data of the active side wing of the car seat. The active side wing of the car seat is equipped with a pressure acquisition controller, which can send the collected airbag pressure data to the industrial computer 7 through the CAN bus 3. The industrial computer 7 parses the received airbag pressure data to obtain the maximum pressure value during the inflation process of the active side wing airbag of the car seat.
[0072] The display module 8 is electrically connected to the industrial computer 7 and is used to display the detection results.
[0073] In this embodiment, the control processing device serves as the control center of the entire equipment. During the detection process, it can simulate the actual vehicle operating environment, thereby driving the active side wings of the seats to be detected on the assembly line to operate in accordance with the simulated environment. After generating a special detection process for the seats to be detected, the control processing device controls the detection components to perform detection according to the detection process during operation, thereby achieving comprehensive and accurate detection. At the same time, the control processing device can also judge the detected data, and also realize in-depth mining of the performance of the active side wings of the car seats and accurate identification of faults.
[0074] In the embodiment of the present application, the current sensor 4 is connected in series between the DC power supply 6 of the detection component and the seat to be detected. When the seat to be detected is detected, the current data on the seat to be detected is monitored and collected in real time.
[0075] Specifically, the seat to be tested is powered by a DC power supply 6 to drive the active wing to operate, and the current sensor 4 is connected in series between the DC power supply 6 and the active wing system. When the active wing is running, the current sensor 4 can monitor its current changes in real time and collect the current data of the active wing of the car seat under the control of PLC2.
[0076] In this embodiment, the current data of the active side wing of the automobile seat is monitored and collected in real time by the current sensor 4, thereby ensuring the accuracy and integrity of the current data.
[0077] In an embodiment of the present application, the storage space of the control processing device also stores a working mode program, and the working mode program is used to represent the automatic mode and the manual mode.
[0078] The automatic mode is used to perform a fully automatic test on the various functions of the seat to be tested. The test process tests various functions in sequence according to the start command generated by the industrial computer 7;
[0079] The manual mode is used to individually test each function of the seat to be tested, and the test items are selected through the display module 8;
[0080] The storage medium corresponding to the storage space of the control processing device is arranged inside the industrial computer 7 , and the automatic mode and the manual mode can be selected through the display module 8 .
[0081] Specifically, after the seat to be inspected arrives at the inspection station and before the seat to be inspected is inspected, the user can select a mode through the display module 8 and select a required mode to inspect the seat to be inspected.
[0082] Among them, the automatic mode is mostly used in the production inspection process of the seats to be inspected. After the inspection is completed, the inspection results are generated according to the acquired inspection data and the inspection standards of the seats to be inspected. The manual mode is mostly used in the repair and debugging process of the seats to be inspected. After the faulty seats to be inspected are repaired, they are transported to the inspection station through the assembly line. After the inspection equipment is connected, the user inspects the maintenance parts of the seat to be inspected through the manual mode. After the inspection results are qualified, the overall function is tested through the automatic mode.
[0083] In this embodiment, by setting a variety of working modes, flexible control of the detection method is achieved, so that the detection equipment of the present application can detect seats in different conditions, improve the convenience of the detection process, and simplify the debugging process.
[0084] In an embodiment of the present application, before the seat to be inspected is inspected, the display module 8 is also used to receive configuration parameters of different seats input by the user, as well as configuration commands of system parameters input, and send the configuration parameters and configuration commands to the industrial computer 7, so that the industrial computer 7 can perform targeted configuration of the inspection process and inspection standards of the seat to be inspected according to the received configuration parameters and configuration commands.
[0085] In this embodiment, various parameters are flexibly set through the display module 8, and the set parameters are sent to the industrial computer 7. The industrial computer 7 configures a targeted detection process, which greatly improves the flexibility and applicability of the detection, and realizes that for car seats produced by different manufacturers, the active side wing function of the car seat can be fully tested through simple settings and adjustments, which not only reduces the test cost, but also greatly improves the test efficiency.
[0086] In an embodiment of the present application, the storage space is also used to store seat inspection standards of different factories and inspection configuration parameters of different models of seats.
[0087] Furthermore, the storage space also stores system operating parameters and detection processes of various functions. The user can view the contents stored in the storage space through the display module 8 and change them. When calling, the user sends a command to the industrial computer 7 through the display module 8 to call the contents stored in the storage space.
[0088] Among them, the industrial computer calls the test standards in the storage space according to different test processes to determine whether the test data is qualified, thereby generating a test result.
[0089] This embodiment stores a variety of pre-set parameters through storage space, thereby achieving flexible calling of parameters, further improving the flexibility and convenience of detection, and enabling the detection equipment to be widely used in various automobile research and development and production scenarios.
[0090] In an embodiment of the present application, the industrial computer 7 is connected to the production management system through a network. After the seat to be inspected is inspected, the industrial computer 7 summarizes the inspection results of various functions, generates a total inspection result, and sends it to the production management system for statistics.
[0091] The test results of each function are the inflation current result, maximum pressure result, deflation current result, inflation displacement result and deflation displacement result of the right active side wing airbag of the car seat, and the inflation current result, maximum pressure result, deflation current result, inflation displacement result and deflation displacement result of the left active side wing airbag of the car seat.
[0092] Furthermore, only in the automatic mode can the industrial computer 7 summarize and upload the test results. In the manual mode, the industrial computer 7 only generates the test results of the required test functions and does not involve uploading to the production management system.
[0093] Among them, the interaction methods between the industrial computer 7 and the production management system include at least SQL (database), MSMQ (message queue) and JSON (text-based data exchange format), and the user can select a suitable interaction method according to actual needs.
[0094] In this embodiment, through the interaction between the industrial computer 7 and the production management system, the test results are uploaded to the production management system for statistics, which improves the intelligence level of the factory's production management and realizes the factory's visualization of the seat production results, which is conducive to improving the factory's refined management of seat production and improving existing production technology.
[0095] In an embodiment of the present application, the industrial computer 7 is also used to generate a diversion instruction based on the judgment result sent by the production management system, and send the diversion instruction to the PLC2.
[0096] The judgment result is generated by the production management system based on the overall test results to determine whether the seat to be tested is qualified.
[0097] The diversion instruction is used to instruct PLC2 to perform diversion operations on the seats to be inspected on the assembly line.
[0098] Specifically, the diversion instruction includes an allow diversion instruction and a prohibition of separation instruction. PLC2 interacts with the assembly line through I / O (digital input and output). When the overall detection result is qualified, the production management system sends the judgment result to the industrial computer 7. After receiving the instruction, the industrial computer 7 generates a prohibition of separation instruction and sends it to PLC2. The output signal of the digital output point 1 of PLC2 changes from false to true. After the assembly line detects that the output signal of the digital output point 1 changes to true, the seat after the inspection is controlled to enter the next process. When the overall detection result is unqualified, the production management system sends the judgment result to the industrial computer 7. After receiving the instruction, the industrial computer 7 generates a allowance of diversion instruction and sends it to PLC2. The output signal of the digital output point 2 of PLC2 changes from false to true. After the assembly line detects that the output signal of the digital output point 2 changes to true, the seat after the inspection is controlled to enter the rework area.
[0099] Among them, the interaction methods between PLC2 and the assembly line also include Modbus (serial communication protocol), TCP / IP protocol (Ethernet communication protocol) and / or S7 protocol (Siemens communication protocol). Users can choose the appropriate interaction method according to actual needs.
[0100] In this embodiment, the overall inspection result is judged by the production management system (MES), and the industrial computer 7 controls PLC2 to perform diversion operations according to the judgment result, which further improves the intelligence level of factory production. Moreover, after the diversion function is realized intelligently, the diversion error rate can be effectively reduced, thereby realizing accurate classification of automobile seats.
[0101] A second aspect of the present application provides a method for detecting an active side wing of a vehicle seat, which is applied to an active side wing detection device for a vehicle seat. The method may include:
[0102] S1: Connect the detection device to the seat to be detected, scan the barcode on the seat after the connection is completed, and send the scanned information of the seat to be detected to the industrial computer 7.
[0103] S2: The industrial computer 7 generates a start instruction according to the received information of the seat to be tested, and the test equipment tests the seat to be tested according to the start instruction.
[0104] S3: The industrial computer 7 sends the simulated left-turning operating condition data to the seat to be tested, so as to drive the right air bag of the active side wing of the car seat to inflate, and collects the inflation current data and the inflation displacement data of the right air bag through PLC2 and sends them to the industrial computer 7. At the same time, the industrial computer 7 receives the maximum pressure data of the right air bag fed back by the car seat. After completing the right air bag inflation test, the industrial computer 7 sends the simulated straight-line driving operating condition data to the seat to be tested, so as to drive the right air bag of the active side wing of the car seat to deflate, and collects the deflation current data and the deflation displacement data of the right air bag through PLC2 and sends them to the industrial computer 7.
