Description

Technical Field

[0001] This invention relates to the field of automotive front door hood size analysis technology, specifically, to an automotive front door hood size detection device. Background Technology

[0002] The contours and dimensions of automotive assemblies such as doors and hoods are crucial to the aesthetic fit of the vehicle's exterior panels. Severe dimensional deviations can lead to significant functional problems. Therefore, controlling the dimensions of exterior panel assemblies is essential for both vehicle functionality and aesthetics. Currently, the industry relies heavily on physical inspection tools for dimensional analysis and inspection of assembly parts. These tools require manual loading, measurement, recording, and analysis. As assemblies weighing over 15 kg place a heavy burden on personnel. Furthermore, the inspection results depend on manual measurement, leading to significant errors and inconsistent outcomes. This results in a large volume of data for analysis, and the analysis methods are too simplistic. This approach cannot adequately simulate the impact of local dimensional changes on the overall dimensions of assembly parts, nor can it compare and analyze the influence of welding processes and techniques on dimensional deviations. Consequently, the analysis and optimization cycle for dimensional issues is lengthy, and the methods fail to meet the increasingly stringent quality requirements of automotive products.

[0003] When using physical inspection fixtures to check and analyze dimensional issues, it is known that after manually assembling the parts, the assembly parts are placed in the designated position of the fixture, and the outer contour surface of the assembly parts is compared with the contour block for inspection. The inspection process often relies on flatness gauges or feeler gauges for manual inspection, and the measurement results also need to be recorded and the data processed and analyzed later, which requires high personnel skills.

[0004] Since the product's outline and surface design are mostly curved, the accuracy of manual measurement is about 0.3mm. The measurement results also vary from person to person and are greatly related to the choice of measurement angle and position. The results can only be used to judge trends and cannot accurately guide size optimization.

[0005] Physical inspection fixtures can only detect external dimensions and cannot verify or compare the impact of local dimensional changes on the overall dimensions of assembly parts, nor can they detect the degree of influence of welding processes and techniques on out-of-tolerance dimensions.

[0006] Traditional dimensional problem analysis can only be done through tedious processes such as manual loading, alignment, measurement, data processing, and analysis. This process requires high skill levels from personnel, involves a large workload, and is highly complex. Furthermore, the sharp corners of sheet metal parts can easily cause mechanical injuries to employees. Summary of the Invention

[0011] Preferably, the calculation template includes a best-fit alignment contour surface detection template, an RPS alignment gap contour surface detection template, and a custom alignment point contour surface detection template.

[0012] Preferably, the support component includes a base frame and multiple vertical supports, the bottom end of the vertical supports is fixedly connected to the base frame, and the top end of the vertical supports is used to fix the assembly positioning system, the sub-assembly positioning system and the part positioning system.

[0013] Preferably, the simulation tool includes a fixing mechanism, a support rod, a translation mechanism, and a pressing head. The fixing mechanism is used to fix the support rod and the base frame, and the pressing head is movably connected to the support rod through the translation mechanism.

[0014] Preferably, the pressing head includes a clamping member, an angle adjusting member, and a connecting member. The connecting member is used to fix the translation mechanism and the angle adjusting member, and the clamping member is rotatably connected to the angle adjusting member.

[0016] Preferably, a roller mechanism is provided at the bottom of the base frame.

[0017] The automotive front door hood dimension detection device of this invention has the following beneficial effects: By spatially positioning the parts using bracket components and combining simulation tools with on-site analysis requirements, it can perform simulated analysis experiments on part dimensions. With the assistance of data acquisition, data technology, and data display, analysis results can be quickly presented, providing efficient and accurate data support for dimension problem analysis. It also enriches the methods for dimension problem analysis, providing more data verification methods and avoiding problems such as a single dimension problem analysis method and slow optimization progress. This effectively improves the efficiency of dimension problem resolution, thereby rapidly improving the overall vehicle product quality. The results output by the detection system can effectively analyze and monitor the influence of the welding process, with stronger data accuracy and practicality, providing more verification methods for problem analysis and avoiding the waste of cost and time in dimension optimization caused by conjecture. Through the cooperation of the bracket components and the detection system, more accurate identification and analysis of the dimensional data such as part surface, contour, and features can be achieved, effectively supporting the improvement of product dimensional accuracy and thus improving the aesthetics of flush gaps in external accessories. The integrated setting of different brackets with different detection templates allows multiple parts to use the same system, achieving high resource integration and effectively reducing the cost of outsourcing inspection fixtures for each part. The support components, detection system, collaborative robot, and control system work together with preset templates and trajectories to reduce manual workload, enabling one-click measurement startup and saving time on problem analysis. The coordination of the support components and detection system makes dimensional problem analysis methods visible and understandable, avoiding the problem that dimensional problem analysis teaching can only rely on abstract imagination and verbal explanations of methods. This approach can be used for training in dimensional problem analysis methods, which is beneficial for cultivating professional talent. Attached Figure Description

Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment".

Other explicit and implicit definitions may also be included below.

[0026] To at least partially address one or more of the aforementioned problems and other potential issues, embodiments of this disclosure provide a vehicle front door hood size detection device, such as... Figure 1 and Figure 2As shown, it includes: support component 1, detection system 2, control system 3, loading gripper 4, collaborative robot 5, and parts storage platform 6.

[0027] A parts storage platform 6 is used to place parts; a gripper 4 is used to grip parts; a support component 1 is used to fix and clamp parts; the detection system 2 includes a data acquisition element 201, a data calculation system 202, and a data display system 203. The data acquisition element 201 is used to acquire part data, the data calculation system 202 is used to determine the part size change value based on the part data, and the data display system 203 is used to output the part size change value; a collaborative robot 5 is used to move the gripper 4 and the data acquisition element 4; the control system 3 is communicatively connected to the gripper 4, the detection system 2, and the collaborative robot 5. The control system 3 is used to output detection commands, including gripping commands, part movement commands, and scanning commands. The part movement commands are used to control the collaborative robot 5 to move the part through the gripper 4, and the scanning commands are used to control the collaborative robot 5 to move the data acquisition element 201 to scan the part to acquire part data. In some embodiments, the support component 1 also includes a simulation tool, one end of which is fixedly connected to the support component 1, and the other end of which is movably abutted against the part.

[0028] Specifically, the parts storage platform 6 is equipped with storage racks for storing parts, reducing deformation caused by stress during the process. The parts include target parts, sub-assembly parts, and assembly parts.

[0029] The bracket component includes an assembly positioning system, a sub-assembly positioning system, and a part positioning system. The assembly positioning system is used to fix and clamp the assembly parts, the sub-assembly positioning system is used to fix and clamp the sub-assembly parts, and the part positioning system is used to fix and clamp the target part. For example, bracket component 1 includes an assembly positioning system 101, an inner plate sub-assembly positioning system 102, and a simulation tool 103. Positioning systems 101 and 102 are used to position the assembly parts and sub-assembly parts, respectively.

[0030] The assembly bracket positioning system 101 includes 3 main Z-axis positioning points and 4 auxiliary Z-axis positioning points. An adjustment mechanism is set in the Z-axis of the auxiliary positioning points to adjust the position of the auxiliary Z-axis positioning points. The adjustment mechanism is used to adjust the fit between the positioning support and the front cover assembly support surface. The Z-axis positioning points are evenly distributed around the front cover. Positioning holes that cooperate with the bolts of the left and right hinges of the front cover are arranged. The left side is a long hole that restricts the X-axis, and the right side is a round hole that restricts the XY-axis. A hand-held tightening nut that can cooperate with the bolts of the front cover assembly is set below the positioning holes. The above positioning points cooperate to form the front cover assembly component positioning support system, ensuring that the front cover is restricted to six degrees of freedom of rotation and translation in the X / Y / Z directions.

[0031] The inner panel sub-assembly bracket positioning system 102 includes three main Z-axis positioning structures shared with the assembly positioning system Z-axis positioning. A clamping system is provided above the Z-axis positioning system for clamping the front cover inner panel assembly. The middle left side of the front cover inner panel assembly has an elongated hole to restrict the X direction, and the middle right side has a round hole to restrict the XY direction. The above positioning points cooperate to form a positioning support system for the inner panel assembly parts of the front cover, ensuring that the rotation and translation of the front cover inner panel assembly parts in the X / Y / Z directions are restricted to six degrees of freedom.

[0032] The simulation tool 103 is equipped with a pressing head and has a scale to accurately record the simulated stroke of the pressing head. The simulation tool 103 is connected to one end of the bracket component 1, and the other end is used to press or lift any area of ​​the part. The angle of the pressing head can be adjusted according to the arc surface of the part to ensure that the curved surface of the part is subjected to vertical pressing force, so as to prevent damage to the surface of the part caused by non-vertical force application. By accurately adjusting the pressing head to press or lift the part downward, the influence of different local deformations of the part on the dimensions of other areas can be analyzed. The simulation tool works with the front cover assembly bracket to analyze and simulate the influence of local dimensional changes in any area on the dimensional changes of other areas of the front cover.

[0033] The part is placed on the support component 1. The control system 3 selects the template state and sends an instruction to control the data acquisition element 201 of the detection system 2 to collect data and send it to the data calculation system 202. The data calculation system calculates the impact of the current local size of the part on the size of other areas according to the fixed template, and presents the data analysis results on the data display system 203.

[0034] Alternatively, without using simulation tool 103, data can be directly collected and calculated on the parts before and after welding in the manner described above. This provides data for analyzing dimensional changes during the welding process, enabling the analysis and investigation of factors affecting dimensional dimensions, and providing accurate data support for dimensional problem analysis. Furthermore, the above method can be used to directly output the edge and contour dimensional data of the parts, obtaining dimensional deviations that are closer to the true value of the part's deviation. This data can be directly used for dimensional problem optimization, accelerating the efficiency of dimensional problem parts.

[0035] The detection system 2 includes a data acquisition element 201, a data calculation system 202, and a data display system 203. The data calculation system is equipped with a variety of detection templates, including the best fit alignment contour surface detection template, the RPS alignment gap contour surface detection template, and the custom alignment point contour surface detection template. The difference between the templates lies in the number and position of the system comparison points selected for the part. This is used to analyze data changes from multiple angles, so as to identify key points that affect the size and then determine the optimization scheme for size adjustment and optimization.

[0036] The control system 3 inputs template types and requires control data acquisition element 201 to scan and pick up data according to the contour trajectory of the front cover assembly and the contour dimensions of the front cover inner panel assembly. The picked-up data is sent to the data calculation system 202, which calculates and outputs comparison values ​​according to fixed templates / custom templates, and presents them in the data display system. The detection template can be set as needed to facilitate one-click measurement by users. It can also be operated without professional testing and analysis personnel, making the analysis process simple, fast and flexible.

[0037] The control system 3 sends instructions to control the collaborative robot 5 to drive the upper gripper 4 to pick up the front cover assembly or the front cover inner panel assembly placed on the parts storage platform 6, and to position the parts on the designated positioning system on the support component 1 according to a fixed trajectory. The control system 3 is equipped with different templates for the front cover assembly and the front cover inner panel assembly. According to the selected template, the control system 3 sends instructions to control the data acquisition element 201 to scan and pick up data according to the contour surface trajectory of the front cover assembly and the contour surface dimensions of the front cover inner panel assembly. The data acquisition system 201 then sends the data to the data calculation system 202 for data processing and calculation. The control system 3 can preset the best fitting alignment contour surface detection template, the RPS alignment gap contour surface detection template, and the custom alignment point contour surface detection template. The number of templates can also be increased as needed. It can realize the detection and analysis of multiple different parts separately. Compared with the original method, which requires a separate inspection tool for each part, it greatly saves the quality inspection and analysis cost.

[0038] The upper gripper 4 is equipped with a flexible gripper, which can change the gripping point on the gripper according to the preset instructions of the control system 3, so as to adapt to the front cover assembly and the front cover inner panel assembly parts.

[0039] According to the instructions of the control system 3, the collaborative robot 5 can drive the gripper to grab the front cover assembly and the front cover inner panel assembly parts. It can also drive the data acquisition element 201 to perform data scanning and picking according to the contour trajectory of the front cover assembly and the contour dimensions of the front cover inner panel assembly according to the instructions sent by the control system 3.

[0040] In some embodiments, the scanning instruction includes scanning trajectory information and calculation template information. The collaborative robot 5 includes multiple scanning trajectories, and the detection system 2 includes multiple calculation templates. The multiple scanning trajectories and multiple calculation templates correspond one-to-one. The collaborative robot 5 moves the data acquisition element 201 according to the scanning trajectory information, and the data calculation system 202 determines the part size change value based on the part data and the calculation template information. In some embodiments, the calculation template includes a best-fit alignment contour surface detection template, an RPS alignment gap contour surface detection template, and a custom alignment point contour surface detection template.

[0041] Specifically, when analyzing the impact of local dimensional deformation on the overall dimensions, the user selects the part type in the control system 3 according to their needs. The control system 3 then sends instructions to control the upper gripper 4 and the collaborative robot 5 to grasp the part and place it on the corresponding bracket on the support component 1. The simulation tool 1 is placed in the simulation area corresponding to the part size. The angle of the pressing head on the simulation tool 103 is adjusted according to the curved surface of the part to ensure that the curved surface of the part is subjected to vertical clamping force. By accurately adjusting the pressing head to press down or lift the part, the influence of different local deformations of the part on the dimensions of other areas is analyzed. The user selects the corresponding template or a custom template in the control system, and the control system 3 sends control instructions to the data acquisition element 201. The data acquisition element 201 completes data acquisition and transmits it to the data calculation system 202 to complete the calculation results, thus completing a simulation analysis and detection of the impact of local deformation of the part on the overall dimensions. This detection can be applied before the part size is adjusted to quickly find size optimization measures and accelerate the size optimization process.

[0042] When analyzing the dimensional impact of the welding process, based on user selection, the control system 3 issues commands to control the collaborative robot 5 to drive the upper gripper 4 to pick up the sub-assembly part and place it in the support component 4. The control system 3 then sends commands to control the collaborative robot 5 to drive the data acquisition element 201 to collect part data according to a preset trajectory and sends the data to the data calculation system 202 for calculation, outputting the detection value. The sub-assembly part is then manufactured into the final assembly according to the welding process, and the detection value is repeated following the above steps. The control system compares the two sets of data according to a fixed template and outputs the change status. Users can directly determine the dimensional impact of the current welding process based on the result change status, thereby quickly identifying key influencing factors of dimensional problems and accelerating dimensional problem analysis.

[0043] When analyzing changes in the dimensions of the contour surface, the above steps can be followed to directly output the dimension detection deviation value. Furthermore, the template can be flexibly changed through the control system to compare the relative positions of the dimensions of any number of regions or the contour dimensions, thus achieving accurate result output.

[0044] The positioning elements of bracket component 1 fix the six spatial degrees of freedom of the part, and together with the inspection system, it can accurately detect the contour, surface dimensions and feature dimensions of the part, effectively improving the accuracy of the analysis data and achieving the goal of precise data to guide dimensional optimization. According to the requirements, the simulation tool 103 is used to simulate the local deformation of the part. According to the requirements, the preset template is selected and the detection system extracts and processes the data, reducing the difficulty of dimensional analysis while meeting the simulation of various analysis conditions of the vehicle's outer body panels. It can quickly identify the key influencing factors of dimensional optimization and guide dimensional optimization, effectively improving the analysis and optimization level of outer body panel dimensional problems. The control system drives the collaborative robot to achieve precise layered control, which can reduce the need for personnel and achieve resource integration.

[0045] In some embodiments, the bracket component includes a base frame 11 and a plurality of vertical brackets 12. The bottom end of the vertical bracket 12 is fixedly connected to the base frame 11, and the top end of the vertical bracket 12 is used to fix the assembly positioning system, the sub-assembly positioning system and the part positioning system.

[0047] In some embodiments, the simulation tool includes a fixing mechanism 141, a support rod 142, a translation mechanism, and a pressing head. The fixing mechanism is used to fix the support rod and the bottom frame, and the pressing head is movably connected to the support rod through the translation mechanism.

By adjusting the fastening screw, the adjusting block can move up and down relative to the support rod 142, and the adjusting rod 143 can move relative to the support rod 142 in a plane perpendicular to the support rod 142.

The connecting member is used to fix the translation mechanism and the angle adjusting member, and the clamping member and the angle adjusting member are rotatably connected.

[0050] Specifically, such as Figure 4 and Figure 5As shown, the bottom end of the clamping member 146 is used to abut against the part. The clamping member 146 is rotatably connected to the angle adjusting member 145, so that the angle of the clamping member 146 can be adjusted according to actual needs. The angle adjusting member 145 is a disc structure with a limiting hole. The limiting hole is an arc-shaped hole around the disc.

[0052] Specifically, the mounting holes are threaded through holes formed on the base frame 1.
