Description

Technical Field

[0001] The present invention relates to the technical field of automobile assembly, and more particularly to a front-mounted anti-misassembly recognition system for door assemblies of multiple vehicle models. Background Art

[0002] In order to effectively control the investment cost of new vehicle models, mixed-flow production of multiple vehicle models is adopted in the welding production line. The same is true for the sub-assembly line of welding opening parts. There are many varieties of four-door and two-hood parts for multiple vehicle models, and the differential features are not obvious. Moreover, due to the factors of the styling features of the covering parts, the requirements for anti-misassembly technology of parts are higher and the implementation is more difficult. Especially in the hemming station of the inner and outer door panels, due to the design structure limitation of the hemming die, the anti-misassembly mechanism for different outer door panels of multiple vehicle models cannot be arranged, and only manual recognition or special die methods can be used, which increases the risk of manual misassembly and the investment cost of vehicle models.

[0003] Regarding the hemming stations of the inner and outer door panels of multiple vehicle models, the outer door panels of multiple vehicle models have the same shape, but the positions of the outer panel assembly holes are different. Due to the small difference points, in order to reduce the investment cost, the die sharing process is adopted. However, since the different assembly holes of the outer door panels of multiple vehicle models coincide with the die surface, it is impossible to directly or indirectly identify the differences through traditional detection elements. Usually, the manual assembly recognition process is adopted. Since the difference points are identified manually, the accuracy rate cannot reach 100%, which is prone to misassembly and miswelding, greatly increasing the risk of scrapping of subsequent process assembly parts, increasing the investment cost of new vehicle models, increasing the floor area of the multiple vehicle model line, and being unfavorable for subsequent production line capacity expansion and new vehicle model input requirements. The vehicle model recognition is usually installed after the manual assembly of parts to the hemming die and all the die clamps are tightly clamped. When there is a manual assembly error, it is necessary to open all the die clamps to replace the parts, which greatly wastes the man-hour of manual operation. Summary of the Invention

[0004] In view of the above deficiencies in the prior art, the present invention provides a front-mounted anti-misassembly recognition system for door assemblies of multiple vehicle models, which not only realizes the acquisition of detection signals for multiple differential points of doors of multiple vehicle models and automatic vehicle model matching, but also avoids the risk of misassembly of parts caused by manual recognition of parts, and reduces manufacturing costs such as vehicle repair and scrapping.

[0005] In order to achieve the above object and other related objects, the technical solution provided by the present invention is as follows:

The A-model door inner panel window frame detecting element is used for detecting whether the A-model door inner panel window frame is positioned in place. The B-model door inner panel window frame detecting element is used for detecting whether the B-model door inner panel window frame is positioned in place; proximity travel switches are arranged on each detecting element in the door inner panel detecting component.

[0016] Further, the detecting positions and detecting distances of the detecting elements on the detecting device are accurately set, and the in-place signals of the detecting elements can be automatically fed back to the hemming island electrical control system.

[0017] Further, the outer door panel photoelectric detecting device includes an outer door panel glue application platform and a photoelectric error-proofing detecting component, and the photoelectric error-proofing detecting component is installed on the support of the outer door panel glue application platform.

[0018] Further, the photoelectric error-proofing detection component includes a first photoelectric detection element, a second photoelectric detection element, and a third photoelectric detection element. The first photoelectric detection element is used to detect the in-place detection of the common plane of the outer panels of multiple vehicle models. The second photoelectric detection element is used to perform a primary error-proofing difference detection on a first difference feature point of the outer panel of the vehicle door.

[0021] Further, the front-mounted button execution control unit includes a manual button mechanism and a system implementation progress display switch. The manual button mechanism is the system start switch. The color of the system implementation progress switch has three colors: red, yellow, and green. The green display of the switch represents that the system is running normally and the vehicle models are matched. The yellow display of the switch represents that the in-place detection feedback signal of the vehicle door mold does not meet the system start condition and there is a system start failure.

[0022] Further, the visual HMI display system is connected to the hemming island electrical control system in real time, and the device detection signal information is displayed through a 2D plane device for human-machine interaction.

Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0035] Embodiment: As Figure 1 shown, a pre-positioned anti-misidentification system for multi-model vehicle door assemblies, the system includes:

[0036] A hemming island electrical control system, which is used for judging and feedback of signal information of multiple vehicle models;

[0037] A door hemming die in-place detection device, which is used for in-place detection of inner door panel and outer door panel parts;

[0038] An inner door panel positioning detection device, which is used for precise positioning of the inner door panel assembly, and the positioning deviation is ±0.5 mm;

[0039] An outer door panel photoelectric detection device, which is used for accurate positioning of the outer door panel and glue application operation of the outer door panel, and the positioning accuracy deviation is ±1 mm;

[0040] A pre-positioned button execution control unit, which is used for manual operation and fault warning signals;

[0041] A visual HMI display system, which is used for 2D simulation display of station tooling equipment and equipment detection signals;

[0042] As Figure 3 shown, the pre-positioned button execution control unit is connected to the hemming island electrical control system as an output execution unit of the hemming island electrical control system, the visual HMI display system is connected to the hemming island electrical control system as an output signal source of the hemming island electrical control system, and the door hemming die in-place detection device, the inner door panel positioning detection device, and the outer door panel photoelectric detection device are connected to the hemming island electrical control system as signal collection and processing units.

[0043] Furthermore, the inner door panel positioning detection device includes a multi-model common inner door panel positioning gripper and an inner door panel detection component, and the inner door panel detection component is installed on the support structure of the multi-model common inner door panel positioning gripper.

[0044] Further, the door inner panel detection assembly includes a multi-model door inner panel assembly in-place detection element, an A-model door inner panel window frame detection element, and a B-model door inner panel window frame detection element. The multi-model inner panel assembly in-place detection element is used to detect whether the common plane of the multi-model door inner panel is positioned in place. The A-model door inner panel window frame detection element is used to detect whether the A-model door inner panel window frame is positioned in place. The B-model door inner panel window frame detection element is used to detect whether the B-model door inner panel window frame is positioned in place. Proximity travel switches are provided for each detection element in the door inner panel detection assembly.

[0045] Further, the detection positions and detection distances of the respective detection elements on the detection device are accurately set, and the in-place signals of the detection elements can be automatically fed back to the hemming island electrical control system.

[0046] Specifically, as Figure 4 shown, the door inner panel positioning detection device mainly consists of a multi-model common door inner panel positioning gripper 13 and a door inner panel detection assembly (11, 12, 14). The common door inner panel positioning gripper is mainly a double-sided inner panel positioning structure, and is mainly used to accurately position the door inner panel assembly. The positioning deviation is ±0.5 mm, providing a hardware guarantee for the error-proof identification detection accuracy and repeated detection accuracy of the multi-model door inner panel assembly. The door inner panel detection assembly (11, 12, 14) is installed on the door inner panel positioning gripper support structure, and includes a multi-model door inner panel assembly in-place detection element 14, an A-model door inner panel window frame detection element 11, and a B-model door inner panel window frame detection element 12. The multi-model door inner panel assembly in-place detection element 14 is used to detect whether the common plane of the multi-model door inner panel is positioned in place. To ensure the accuracy of the in-place detection, the detected common plane needs to be larger than 30 mm * 30 mm. The A-model door inner panel window frame detection element 11 is used to detect whether the A-model door inner panel window frame is positioned in place. The B-model door inner panel window frame detection element 12 is used to detect whether the B-model door inner panel window frame is positioned in place. Proximity travel switches are used for the detection elements in the door inner panel detection assembly. To ensure the detection accuracy, the relevant parameters such as the detection plane size, detection distance, and difference point size of the detection elements are shown in Table 1. When the detection positions and detection distances of the respective detection elements on the detection device are accurately set, the in-place signals of the detection elements can be automatically fed back to the control system. For example, when the detected part is in place, the travel switch signal feedback is (I), and when the detected part is not in place, the travel switch signal feedback is (O). The A and B model door inner panel assembly model matching signal parameter diagrams are shown in Table 2.

[0050] Table 2

[0051] Furthermore, the photoelectric detection device for the outer door panel of the vehicle includes an outer door panel gluing platform and a photoelectric error-proofing detection component, and the photoelectric error-proofing detection component is installed on the bracket of the outer door panel gluing platform.

[0052] Furthermore, the photoelectric error-proofing detection component includes a first photoelectric detection element, a second photoelectric detection element, and a third photoelectric detection element. The first photoelectric detection element is used to detect the in-place detection of the common plane of the outer door panels of multiple vehicle models. The second photoelectric detection element is used for the first anti-error difference detection of the first difference feature point of the outer door panel. The third photoelectric detection element is used for the second anti-error difference detection of the second difference feature point of the outer door panel.

[0053] Furthermore, diffuse reflection photoelectric switches are provided for each photoelectric detection element of the photoelectric error-proofing detection component. The emitter and the receiver are integrated. When the part is in place, the photoelectric detection element emits a light beam onto the part to form a reflected light, and the reflected light returns to the receiver. The photoelectric switch feeds back a signal to the hemming island electrical control system.

[0054] Specifically, the photoelectric error-proofing detection device for the outer door panel of the vehicle mainly consists of an outer door panel gluing platform 15 and a photoelectric error-proofing detection component (16, 19, 21). The outer door panel gluing platform is used for the accurate positioning of the outer door panel (positioning deviation ±1mm) and the gluing operation of the outer door panel. The photoelectric error-proofing detection component is installed on the bracket 15 of the outer door panel gluing platform. Among them, the first photoelectric detection element 16 is used to detect the in-place detection of the common plane of the outer door panels of multiple vehicle models. The second photoelectric detection element 19 is mainly used for the first anti-error difference detection of the first difference feature point of the outer door panel. To ensure the accuracy of the outer panel anti-error detection, the third photoelectric detection element 21 is mainly used for the second anti-error difference detection of the second difference feature point of the outer door panel. The photoelectric detection element adopts the form of a diffuse reflection switch, and the emitter and the receiver are integrated. When the part is in place, the photoelectric detection element emits a light beam onto the part to form a reflected light. After sufficient reflected light returns to the receiver, the photoelectric switch immediately feeds back a signal (I) to the control system. When the photoelectric channel emitted by the photoelectric detection element passes through the feature hole of the part and no reflected light beam returns to the receiver, the photoelectric switch immediately feeds back an opposite signal (O) to the control system. By comparing the multiple signal information fed back by the detection component with the vehicle model matching signal parameters reserved in the control system, the vehicle model information is confirmed. The vehicle model matching signal parameters of the outer door panel assembly are shown in Table 3.

[0055] Vehicle model First photoelectric detection element 16 Second photoelectric detection element 19 Third photoelectric detection element 21 Vehicle model A 16(I) 19(I) 21(I) Vehicle model B 16(I) 19(O) 21(O)

[0056] Table 3

[0057] Furthermore, the in-place detection device for the door edge wrapping mold includes a door mold and an in-place detection component assembled on the door mold; the in-place detection component includes a first in-place detection element 24 for the inner door panel, a second in-place detection element 25 for the inner door panel, a first in-place detection element 26 for the window frame of the inner door panel, and a second in-place detection element 27 for the window frame of the inner door panel. Proximity travel switches are provided for each detection element of the in-place detection component. The detection positions and detection distances of the detection elements on the detection device are set accurately, and the in-place signals of the detection elements can be automatically fed back to the edge wrapping island electrical control system.

[0058] Specifically, as Figure 7 shown, the in-place detection device for the door edge wrapping mold is mainly composed of a door mold and an in-place detection component (24, 25, 26, 27) assembled on the door mold. The in-place detection component (24, 25, 26, 27) is mainly used to detect the in-place of the inner door panel and the outer door panel parts. The detection principle of the detection component is similar to that of the inner door panel assembly detection, so it will not be elaborated here. In the pre-positioned door assembly error prevention system, the feedback of the in-place detection signal of the door edge wrapping mold is used as the system logic precondition for the implementation of the error prevention system. For example, when the in-place detection signals of the inner door panel and the outer door panel of the door edge wrapping mold both feedback that the parts are in place, it means that the assembly of the first set of parts of the edge wrapping mold is completed, and the previous process can perform the sub-assembly operation of the next set of parts, and the error prevention identification system can be started. The implementation logic diagram of the pre-positioned door error prevention system is shown in Table 4 below.

[0059]

[0060] Table 4

[0061] Specifically, the edge wrapping island electrical control system is designed with a variety of vehicle model signal matching information. During the system implementation process, when the system start signal is received, it first determines whether the system implementation conditions are met. After the conditions are met, by collecting the detection signal information of the door mold, the outer door panel assembly and the inner door panel assembly, and through signal matching and recombination to match with the vehicle model signal information set in the system, it can automatically determine the vehicle model information corresponding to the current signal information, and synchronously feed back the vehicle model information result to the button execution unit and the HMI display system.

[0062] Furthermore, the pre-positioned button execution control unit includes a manual button mechanism and a system implementation progress display switch; the manual button mechanism is the system start switch. The color of the system implementation progress switch has three colors: red, yellow, and green. The green display of the switch represents that the system is running normally and the vehicle model matching is consistent. The yellow display of the switch represents that the in-place detection feedback signal of the door mold does not meet the system start conditions and the system start fails. The red display of the switch represents that the system is running normally, but the vehicle model matching is incorrect.

[0063] Specifically, the front-mounted button execution unit includes a manual button mechanism and a system implementation progress display switch. The manual button mechanism is the system start switch, which is mainly used for manual operation to send a start signal for the error-proofing identification system according to the on-site operation progress by pressing the button. The display switch is mainly used to display the implementation progress of the error-proofing identification system by color. The display switch has three colors: red, yellow, and green. Green of the display switch indicates that the system is running normally and the vehicle models match. Yellow of the switch indicates that the detection feedback signal of the door die in place does not meet the system start conditions, resulting in a system start failure. Red of the switch indicates that the system is running normally, but the vehicle models do not match.

[0064] Furthermore, the visual HMI display system is connected to the hemming island electrical control system in real time, and the device detection signal information is displayed through a 2D plane device for human-machine interaction.

[0065] Specifically, as Figure 6 shown, the visual HMI display system mainly performs 2D simulation display on the station tooling equipment and the device detection signals. The device detection signal information is connected to the 2D device floor plan through the electrical control system. Through human-machine interaction on the display interface, the operation status of the device detection signals can be monitored in real time, and the system operation fault positions can be dynamically displayed. When the display switch of the button execution unit shows red and yellow, it indicates that the operation result of the error-proofing identification system does not match or there is an operation fault. The HMI display system can synchronously display the corresponding vehicle model mismatch information and faults of the error-proofing identification. Operators can view the error and mismatch information points through the HMI system, and combined with the on-site operation situation, they can accurately and quickly identify the misinstalled parts and perform part switching.

[0066] In summary, compared with the traditional method of identifying vehicle models after assembling the inner door panel and the outer door panel to the hemming die, the present invention can identify and judge the matching information of the inner and outer panels in advance through the design of the front-mounted door assembly error-proofing identification system, and achieve vehicle model matching through rapid manual switching of the outer door panel. This avoids problems such as system operation interruption, manual intervention in system replacement of matching parts, and difficult recovery of the electric control system when the vehicle models do not match after the die is clamped. At the same time, through the collection and feedback of the vehicle model matching information of the inner and outer door panel assemblies, system vehicle model information matching processing, signal lamp output of the button execution unit, and real-time fault feedback of the visual HMI display system, the risk of misinstalling parts caused by manual identification of parts is avoided, and the manufacturing costs such as vehicle rework and scrapping are reduced.

[0067] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
