[0022] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0023] Reference Figures 1 to 8 As shown, the present invention provides a method for optimizing the size of automotive interior panels.

[0024] Reference Figure 2 As shown, the size optimization method includes the following steps.

[0025] Step S100: Obtain the outer contour based on the three-dimensional model of the interior panel 100, and design the inspection cavity 210 of the fixture 200 based on the outer contour. The inspection cavity 210 is used to place the interior panel 100.

[0026] Reference Figure 1As shown, the gauge 200 is set on the top of the workbench. The gauge 200 includes multiple positioning blocks, multiple detection blocks 220, a pressing assembly, multiple height measuring instruments 240 and feeler gauges.

[0027] Multiple positioning blocks are set on the top of the workbench, and the top surfaces of the multiple positioning blocks form the bottom wall of the detection cavity 210. Multiple detection blocks 220 are arranged around the periphery of the detection cavity 210. Each detection block 220 has a detection edge on the side facing the detection cavity 210, and the detection edges of the multiple detection blocks 220 form the inner wall of the detection cavity 210.

[0028] The pressing assembly (not shown in the figure) is located above the detection chamber 210. The pressing assembly is provided with multiple spaced pressing blocks. When the interior panel 100 is placed in the detection chamber 210, the pressing assembly drives the multiple pressing blocks to move in the up and down direction to press or release the interior panel 100.

[0029] Multiple height measuring devices 240 are positioned above the detection cavity 210, and the height measuring devices 240 measure the height data of the top surface of the interior panel 100.

[0030] A gap is left between the inner wall of the detection cavity 210 and the outer wall of the interior panel 100, and a feeler gauge is used to measure the width of the gap.

[0031] In step S200, the interior panel 100 is inspected using the inspection tool 200 to obtain the actual gap data between the outer edge of the interior panel 100 and the inner wall of the inspection cavity 210.

[0032] The interior panel 100 is placed in the inspection cavity 210 of the inspection fixture 200, so that multiple positioning blocks jointly support the interior panel 100. Then, the pressing component drives multiple pressing blocks to move downward so that the multiple pressing blocks jointly press the interior panel 100, thereby fixing the position of the interior panel 100. The inspection edges of multiple inspection blocks 220 are arranged around the periphery of the interior panel 100, and the multiple inspection edges form the inner sidewall of the inspection cavity 210.

[0033] Then, a feeler gauge is used to measure the actual gap width between the outer wall of the interior panel 100 and the inner wall of the detection cavity 210. The feeler gauge measures multiple actual gap widths along the outer wall of the interior panel 100, and the multiple actual gap widths are compiled to form actual gap data.

[0034] Step S300: Determine the non-conforming positions of the interior panel 100 and obtain the corresponding out-of-tolerance values ​​based on the actual gap data, theoretical gap data, and gap tolerance data.

[0035] The theoretical gap data package contains the theoretical gap widths at multiple locations between the outer wall of the interior panel 100 and the inner wall of the detection cavity 210, and each theoretical gap width has a corresponding gap tolerance. All gap tolerances are integrated into gap tolerance data.

[0036] The theoretical gap width in the theoretical gap data is compared one-to-one with the actual gap width in the actual gap data. The difference between the actual gap width and the theoretical gap width is calculated. Then, the difference is compared with the corresponding gap tolerance. When the difference exceeds the limit of the gap tolerance, the actual gap width is considered to be out of the acceptable range. Therefore, the measurement position corresponding to the actual gap width can be regarded as the unacceptable position. Then, the difference between the difference and the gap tolerance is calculated to obtain the out-of-tolerance value.

[0037] Step S400: Optimize the three-dimensional model based on the non-conforming locations and out-of-tolerance values ​​to obtain the target three-dimensional model, and manufacture the target interior panel according to the target three-dimensional model.

[0038] Knowing the non-conforming locations and their corresponding deviation values, the non-conforming locations can be adjusted in the 3D model. The dimensions of the 3D model corresponding to the non-conforming locations can be adjusted according to the deviation values ​​to obtain the target 3D model. Then, the target interior panel can be produced based on the target 3D model. The target interior panel can improve the dimensional deviation problem of the interior panel 100 at the non-conforming locations.

[0039] The inspection cavity 210 of the fixture 200 is designed based on the outline of the three-dimensional model of the interior panel 100. The manufactured interior panel 100 is placed in the inspection cavity 210 of the fixture 200, and then the gap width between the outer edge of the interior panel 100 and the inner wall of the inspection cavity 210 is measured to obtain the actual gap data.

[0040] After comparing the actual gap data, theoretical gap data, and gap tolerance data, the non-conforming locations and out-of-tolerance values ​​of the interior panel 100 are determined. Finally, the dimensions of the 3D model are optimized based on the non-conforming locations and out-of-tolerance values ​​to obtain the target 3D model.

[0041] The target interior panel is manufactured from the target 3D model, so that the gap width between the outer edge of the target interior panel and the inner wall of the detection cavity 210 is more in line with the factory requirements, and the splicing gap is more uniform.

[0042] Reference Figure 3 As shown, step S100 includes the following steps.

[0043] Step S110: Divide the outer contour into multiple measurement edges, and design a corresponding detection block 220 according to each measurement edge. The detection block 220 has a detection edge on the side facing the measurement edge.

[0044] The outline of the 3D model is divided into multiple sequentially arranged measurement edges, so that the corresponding detection edge of the detection block 220 can be designed based on the shape of the measurement edge, so that the shape of the detection edge matches the shape of the measurement edge, and ensures that the theoretical gap between the detection edge and the outer edge of the interior panel 100 is more uniform.

[0045] In step S120, multiple detection blocks 220 are arranged in a circle around the outer contour of the outer shape, and multiple detection edges form a detection cavity 210.

[0046] Then, the detection edges of all detection blocks 220 are arranged in a circle according to the shape of the outer contour, so that all detection edges form the shape of the outer contour, and then all detection edges form the detection cavity 210 of the fixture 200.

[0047] Each detection block 220 is equipped with a corresponding translation mechanism 230, which is used to move the detection block 220 away from or closer to the detection cavity 210.

[0048] The translation mechanism 230 moves the detection blocks 220 away from each other, making it easier to place the interior panel 100 in the detection cavity 210 and avoiding damage caused by collision between the interior panel 100 and the detection blocks 220.

[0049] Reference Figure 3 As shown, step S100 also includes the following steps.

[0050] Step S130: Obtain the positioning reference at the bottom of the interior panel 100, and design the positioning block in the detection cavity 210 according to the positioning reference.

[0051] The bottom positioning reference is obtained from the 3D model. Then, based on the positioning reference of the interior panel 100, the top surfaces of multiple positioning blocks are designed. The top surfaces of the multiple positioning blocks form the bottom wall of the detection cavity 210, so that the top surfaces of the multiple positioning blocks of the detection cavity 210 are associated with the positioning reference of the interior panel 100. When the interior panel 100 is placed in the detection cavity 210, the multiple positioning blocks support the interior panel 100, making the position of the interior panel 100 relative to the detection block 220 more accurate.

[0052] The bottom of the interior trim panel 100 is provided with multiple connecting structures, which are used to connect adjacent components. (Refer to...) Figure 4 As shown, before performing step S200, the size optimization method further includes the following steps.

[0053] Step S140: Obtain the connection positions of multiple connection structures based on the three-dimensional model, and design a pressing component based on the multiple connection positions. The pressing component is located above the detection cavity 210. The pressing component is equipped with multiple clamping blocks, and the positions of the multiple clamping blocks are set one-to-one with the multiple connection positions.

[0054] The bottom of the interior panel 100 is provided with multiple connecting structures to connect to other adjacent parts of the car interior. Therefore, all connection positions can be determined in the three-dimensional model. Then, based on the projection of each connection position onto the detection cavity 210, the position of the pressing block of the pressing component is designed so that the pressing block position is located directly above the connection position. Thus, a corresponding pressing block is provided above each connection position of the interior panel 100 in the detection cavity 210.

[0055] In step S150, the interior panel 100 is placed in the detection chamber 210, and multiple pressing blocks are controlled to press down on the interior panel 100.

[0056] When it is necessary to fix the interior panel 100 in the detection cavity 210, all the clamping blocks of the pressing assembly are moved downward to press the interior panel 100, thereby simulating the situation where the interior panel 100 is connected to other adjacent parts by multiple connecting structures, so as to accurately measure the gap width between the inner wall of the detection cavity 210 and the outer edge of the interior panel 100.

[0057] Reference Figure 5 As shown, step S200 includes the following steps.

[0058] Step S210: Obtain the actual height data of the top surface of the interior panel 100, and determine the acceptable height range based on the theoretical height data and height tolerance data.

[0059] Because the interior panel 100 is placed in the detection cavity 210, the interior panel 100 is deformed, causing the edge of the interior panel 100 to curl upward or bend downward, resulting in an error in the measurement of the gap width between the inner wall of the detection cavity 210 and the outer wall of the interior panel 100.

[0060] Multiple clamping blocks of the pressing assembly are used to press the interior panel 100 to reduce deformation. However, the interior panel 100 may still be warped upwards or bent downwards at the positions not pressed by the pressing assembly, making the state of the interior panel 100 in the detection cavity 210 closer to the state in which the interior panel 100 is actually connected to the other adjacent parts.

[0061] Multiple height measuring devices 240 are positioned above the detection cavity 210. The height measuring devices 240 measure the actual height of the top surface of the interior panel 100, and the multiple actual heights are integrated to form actual height data.

[0062] The theoretical height and height tolerance of each height measuring instrument 240 are determined based on the measurement position of that position. All theoretical heights are integrated into theoretical height data, and all height tolerances are integrated into height tolerance data. Finally, the qualified height range is calculated based on the corresponding theoretical height and height tolerance for each group.

[0063] Step S220: Compare the actual height data with the acceptable height range.

[0064] Compare each actual height obtained from the measurement with its corresponding acceptable height range.

[0065] Step S230: When the actual height data is within the acceptable range, the actual gap data between the outer edge of the interior panel 100 and the inner wall of the detection cavity 210 is obtained.

[0066] When all actual height data are within the acceptable range, it can be determined that the deformation of the interior panel 100 is within the acceptable range, and the interior panel 100 can then be placed in the detection cavity 210 for subsequent actual gap measurement.

[0067] If any actual height data exceeds the acceptable height range, the interior panel 100 needs to be inspected or its 3D model adjusted. The position corresponding to the actual height exceeding the acceptable height range should be marked, and then the 3D model of the interior panel 100 should be adjusted.

[0068] Based on the adjusted 3D model, a qualified interior panel 100 is produced, and the actual height of the interior panel 100 at this position is adjusted to the qualified height range. Only when all actual height data are within the qualified height range can the interior panel 100 be placed in the detection cavity 210 for subsequent actual gap measurement.

[0069] Reference Figure 6 As shown, step S200 also includes the following steps.

[0070] In step S240, multiple detection points are set in the gap between the outer edge of the interior panel 100 and the inner wall of the detection cavity 210, and the multiple detection points are distributed at intervals along the outer wall of the interior panel 100.

[0071] Step S250: Use a feeler gauge to measure each detection point to obtain the actual gap width of multiple detection points.

[0072] Step S260: Integrate all actual gap widths into actual gap data.

[0073] The actual gap width of multiple detection points between the outer wall of the interior panel 100 and the inner wall of the detection cavity 210 is measured using a feeler gauge. The feeler gauge measures the actual gap width of multiple detection points along the outer wall of the interior panel 100, and the actual gap widths of multiple detection points are compiled to form actual gap data.

[0074] Reference Figure 7 As shown, step S300 includes the following steps.

[0075] Step S310: Obtain the acceptable range of clearance based on theoretical clearance data and clearance tolerance data.

[0076] Step S320: Obtain the out-of-tolerance value based on the actual gap data and the acceptable gap range.

[0077] The theoretical gap data package contains the theoretical gap widths at multiple locations between the inner wall of the detection cavity 210 and the outer wall of the interior panel 100, and each theoretical gap width has a corresponding gap tolerance. All gap tolerances are integrated into gap tolerance data. Based on the theoretical gap width and gap tolerance, the theoretical gap range can be calculated, and then all theoretical gap ranges are integrated into the gap acceptable range.

[0078] Then, the deviation value is calculated by comparing the actual gap width of the actual gap data with the theoretical gap range corresponding to the acceptable gap range.

[0079] Reference Figure 8 As shown, step S400 includes the following steps.

[0080] Step S410: Set the optimization position in the 3D model based on the defective position.

[0081] Step S420: Optimize the dimensions of the optimized position based on the out-of-tolerance value to obtain the target three-dimensional model.

[0082] Knowing the non-conforming locations and their corresponding out-of-tolerance values, the non-conforming locations can be set as optimized locations in the 3D model. The dimensions of the corresponding optimized locations in the 3D model can be adjusted according to the out-of-tolerance values ​​to obtain the target 3D model. Then, the target interior panel can be produced based on the target 3D model, which can improve the dimensional deviation problem of the interior panel 100 at the non-conforming locations.
