Description

Technical Field

[0001] This utility model relates to the field of embedded head-up display (HUD) product manufacturing technology, and in particular to a testing device for testing embedded HUD products. Background Technology

[0002] An embedded head-up display (HUD) is a type of embedded augmented reality head-up display specifically designed for the dashboard of a particular vehicle model. It uses projection technology and optical design to achieve virtual imaging, projecting virtual images into the driver's field of vision. The complete embedded HUD product, hereinafter referred to as the complete product, mainly includes an optical host that emits imaging information and a chip algorithm program control system. It utilizes a combination of projections from multiple fixed-angle curved mirrors to present virtual supplementary images in the driver's field of vision, thereby achieving a more intelligent driving assistance experience for the driver.

[0003] Currently, customers have increasingly higher requirements for the embedding and matching accuracy of complete machine products. This necessitates factories to quickly determine whether the assembly dimensions, positioning dimensions, and positional dimensions of complete machine products are within standard tolerance ranges. Furthermore, with increasing production volume requirements, it is crucial to maintain inspection quality while ensuring inspection speed. Traditional complete machine product inspection methods primarily rely on coordinate measuring machine (CMM) inspection. This involves employing CMM personnel to first calibrate the equipment, then fixing the fixtures on the complete machine product and verifying their positions. Based on the machine product drawings, a virtual 3D coordinate reference is established on the CMM equipment, and finally, programming is used for the inspection of critical dimensions. This method of inspecting complete machine products is time-consuming per unit, and the output reports require comprehensive analysis by professional quality personnel. Moreover, each inspection requires repeated equipment calibration, fixture position verification, program execution, and virtual coordinate reference establishment, resulting in significant time consumption and a long cycle, leading to low inspection efficiency. On the other hand, differences in the subjective judgment of inspection personnel result in low accuracy of the inspection results, increasing the difficulty of determining the consistency, structural precision, and dimensional standardization of the complete machine product. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for testing embedded head-up display (HUD) products, addressing the problems of low accuracy and low efficiency in existing embedded HUD testing methods.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A testing device for inspecting embedded head-up display (HUD) products includes: a go-stop pin detection module, a reference positioning detection module, a curved screen detection module, and a flip-positioning module. The go-stop pin detection module detects whether the mounting holes and positioning pins of the product are qualified. The reference positioning detection module detects whether the reference surface of the product is qualified and is used to position and fix the product for inspection. The curved screen detection module detects whether the surface contour of the three-dimensional curved screen of the product is qualified. The flip-positioning module abuts against the three-dimensional curved screen, thereby cooperating with the reference positioning detection module to position and fix the product.

[0007] The detection device described in this utility model, by setting a flip-positioning module to fix and adjust the position of the whole product, allows the whole product to be positioned or detected by the go / stop pin detection module, the reference positioning detection module, and the curved screen detection module. It can detect whether the mounting holes, positioning pins, reference surfaces, and the surface contours of the three-dimensional curved screen of the whole product are qualified. The components of the go / stop pin detection module, the reference positioning detection module, and the curved screen detection module are all designed as standard reference parts through structural design. The detection standard of each whole product is uniform, reducing the subjective judgment of the inspectors and thus improving the accuracy of the whole product quality inspection. Furthermore, it eliminates the need for manual inspection of equipment or debugging of programs, simplifying the inspection operation process, shortening the inspection time, improving the inspection efficiency of the whole product, and improving the production efficiency of embedded head-up display whole products.

[0008] Preferably, the testing device for testing embedded head-up display products according to this utility model includes a go / stop pin testing module comprising: a hole size testing component, a hole position testing component, and a pin size testing component; the hole size testing component is used to detect whether the size of the mounting hole is qualified; the hole position testing component can be inserted into the mounting hole and the alignment hole of the reference positioning testing module, thereby detecting whether the opening position of the mounting hole is qualified; the pin size testing component is used to detect whether the size of the positioning pin is qualified.

[0009] As a preferred embodiment of this utility model, by setting a hole size detection component, the size of the mounting hole can be detected, avoiding the situation where the whole product is difficult to embed and install due to unqualified mounting hole size. In conjunction with this, the hole position detection component can be used to detect whether the mounting hole and the alignment hole of the reference positioning detection module can be inserted, and the opening position of the mounting hole can be detected as qualified. The pin size detection component can detect whether the positioning pin size of the whole product is qualified, so as to achieve more precise control of the shape error and orientation error of the part surface of the whole product, and further improve the accuracy of detection.

[0010] Preferably, in the testing device for testing embedded head-up display products according to the present invention, the two ends of the hole size testing component are respectively provided with a through pin and a stop pin with different outer diameters; the two ends of the pin size testing component are respectively provided with a through hole and a stop pin with different through hole diameters.

[0011] The solution described in this utility model uses a pin head and a stop pin head with different outer diameters as hole size detection components. The pin head is used to measure the primary dimension of the mounting hole, and the stop pin head is used to measure the secondary dimension. Generally, the outer diameter of the pin head can be set to be larger than that of the stop pin head to determine whether the mounting hole is within the maximum and minimum allowable values ​​of the hole diameter, i.e., within the set tolerance range. If the mounting hole is within these allowable values, the hole diameter setting of the mounting hole is determined to meet the requirements. Regarding the length of the mounting hole, the lengths of the pin head and the stop pin head can be set to be equal. When the hole size detection component is inserted into the mounting hole, if the pin head or the stop pin head is completely inside the mounting hole, the length of the mounting hole can be determined to be qualified. Similarly, the pin size detection component can measure the outer diameter and length of the positioning pin by measuring the dimensions of the pin head and the stop pin hole. This can avoid misjudgment of the whole product inspection caused by small errors in the mounting hole or positioning pin, and strengthen the control on the basis of the standard tolerance of the whole product, avoid errors caused by processing and manufacturing, reduce the product misjudgment rate, and further improve the reliability of the inspection.

[0012] Preferably, in the testing device for testing embedded head-up display products according to the present invention, the outer diameter tolerance of the guide pin and the stop pin is ≤0.02mm; and the hole diameter tolerance of the guide pin hole and the stop pin hole is ≤0.02mm.

[0013] As a preferred embodiment of this utility model, by setting the specific numerical range of the outer diameter tolerance of the guide pin and the stop pin, and the hole diameter tolerance of the guide pin hole and the stop pin hole to ≤0.02mm, based on the ability to determine whether the main and auxiliary positioning pins and mounting holes of the whole product are qualified, and according to the analysis and calculation of the standard tolerance dimensions of the whole product drawings, the tolerance range of the hole size inspection parts and the pin size inspection parts is clearly defined. At the same time, it can provide an error range of 0.02mm on the basis of the standard tolerance of the whole product, avoid misjudgment of the product due to processing and manufacturing errors, and further improve the reliability of the quality inspection of the whole product.

[0014] Preferably, in the detection device for detecting embedded head-up display products according to the present invention, a primary pin and a secondary pin are arranged adjacent to each other at one end of the hole position detection component; the outer diameter of the secondary pin is larger than the outer diameter of the primary pin; the primary pin is used to cooperate in inserting into the alignment hole, and the secondary pin is used to cooperate in inserting into the mounting hole.

[0015] As a preferred embodiment of this utility model, by setting a primary pin and a secondary pin, when the empty position detection component is inserted into the pre-set alignment hole of the detection device, the primary pin cooperates to insert into the alignment hole. Since the diameter of the primary pin is smaller than that of the secondary pin, it is beneficial to detect the axial alignment of the mounting hole and the alignment hole of the reference positioning detection module, and avoid the misjudgment that the alignment hole can be inserted even if the hole position detection component is tilted, thereby further improving the accuracy of detecting the opening position of the mounting hole.

[0016] Preferably, the curved screen detection module includes multiple ball head detection components, each ball head detection component having a through ball head and a stop ball head at both ends; the through ball head of each ball head detection component is of equal size; the stop ball heads of the multiple ball head detection components decrease in size sequentially, with the largest stop ball head being ≥0.5mm larger than the through ball head.

[0017] As a preferred embodiment of this utility model, the curved screen detection module includes multiple ball-head detection components. During detection, the through-stage ball-head is inserted into the gap between the contour block of the flip positioning module and the three-dimensional curved screen of the complete product, or the stop-stage ball-head cannot be inserted into the gap between the contour block and the three-dimensional curved screen of the complete product, thereby detecting whether the contour of the three-dimensional curved screen is qualified. This avoids subjective or visual judgment of the contour of the three-dimensional curved screen and improves the reliability of the three-dimensional curved screen detection. On this basis, by setting multiple ball-head detection components, with the through-stage ball-heads being of equal size and the stop-stage ball-heads decreasing in size, different contours of different parts of the three-dimensional curved screen can be detected. After detection, the contour gradient set table of multiple complete products can be compiled based on the specific detection tolerance values, improving the accuracy and precision of the detection, reducing misjudgment of the gap size, and further improving the accuracy of the contour detection of the three-dimensional curved screen.

[0018] Preferably, in the testing device for testing embedded head-up display products described in this utility model, the stop ball heads of the plurality of ball head testing components decrease in size progressively with a tolerance of 0.5mm.

[0019] As a preferred embodiment of this utility model, by setting multiple ball head detection components with the size of the stop ball head decreasing in an arithmetic progression with a tolerance of 0.5mm, the upper and lower tolerance dimensions of the standard surface profile of the three-dimensional curved surface are divided into multiple detection ball heads as the gradient detection range standard. By using ball heads of multiple sizes, a more precise position can be defined where the surface profile of the current whole product is within the qualified range, thereby more accurately detecting the profile qualification of the three-dimensional curved surface screen and further improving the detection accuracy.

[0020] Preferably, in the detection device for detecting embedded head-up display products according to the present invention, the reference positioning detection module includes at least one support surface; the support surface can abut against the reference surface of the product and, in conjunction with the plug, can determine whether the reference surface is planar.

[0021] As a preferred embodiment of this utility model, by setting a support surface that can abut against the reference surface, and then using a plug, it is determined whether the plug can be inserted between the support surface and the reference surface. If the plug can be inserted between the support surface and the reference surface, it indicates that the reference surface and the support surface are not parallel, and the position of the reference surface where the plug is inserted is not a plane with other positions of the reference surface. This allows for the detection of whether the reference surface of the whole product is qualified, avoiding the cumbersome operation of establishing a virtual three-dimensional coordinate reference in a coordinate measuring machine, further reducing the difficulty of determining the dimensional standard of the whole product, and enabling more convenient, efficient and accurate detection of the whole product.

[0022] Preferably, the testing device for testing embedded head-up display products according to the present invention further includes a screw hole detection component; the screw hole detection component can be inserted into the screw hole of the product, thereby detecting the position and depth of the screw hole.

[0023] As a preferred embodiment of this utility model, by setting a screw hole detection component, the position and depth of the screw holes of the entire product can also be detected, thereby increasing the detection function of the detection device and enhancing its applicability.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] 1. Through the detection modules of stop pins, reference positioning, curved screen, and flip positioning, the position of the reference and mounting holes and the surface contour of the three-dimensional curved screen can be quickly determined. In actual use, the contour gradient set table of multiple complete products can be compiled, which can save inspection time. There is no need for professional personnel to adjust the parameters of professional inspection equipment. Even inexperienced personnel can quickly start to inspect and judge whether the product is qualified and output inspection reports. In this way, the key dimensions of specially designed complete products can be inspected efficiently. It is low-cost, simple to operate and easy to learn.

[0026] 2. By setting up standardized detection modules for stop pins, reference positioning, curved screens, and flip positioning, the subjective judgment of inspectors can be reduced during the inspection process, thereby improving the accuracy and consistency of the overall product inspection.

[0045] The go / stop pin detection module 1 of this utility model is understood as a columnar pin that can or cannot pass through the mounting hole 101, and also includes a columnar pin that can or cannot accommodate the positioning pin 102. For details, please refer to... Figure 6 , Figure 7 and Figure 8 As shown, the go-stop pin detection module 1 includes: a hole size detection component 11, a hole position detection component 12, and a pin size detection component 13; the hole size detection component 11 is used to detect whether the size of the mounting hole 101 is qualified; the hole position detection component 12 can be inserted into the mounting hole 101 and the alignment hole 21 of the reference positioning detection module 2, and is used to detect whether the opening position of the mounting hole 101 is qualified; the pin size detection component 13 is used to detect whether the size of the positioning pin 102 is qualified.

[0046] It should be noted that the hole size detection component 11 is understood as a comparison or measuring component capable of detecting the size of the mounting hole 101, such as a hole detection pin, a positioning pin 102 detection pin, or a hole position detection pin. A pin is understood as a mechanical component capable of being inserted into or removed from its mating component; for details, refer to... Figure 6 and Figure 8As shown, the hole size measuring component 11 has a through pin head 111 and a stop pin head 112 with different outer diameters at both ends; the pin size measuring component 13 has a through pin hole 131 and a stop pin hole 132 with different through hole diameters at both ends, which can realize the tolerance-based inspection of the mounting hole 101 of the whole machine product 100; as shown Figure 7 As shown, a primary pin 121 and a secondary pin 122 are arranged adjacent to each other at one end of the hole position detection component 12; the outer diameter of the secondary pin 122 is larger than the outer diameter of the primary pin 121; the primary pin 121 is used to be inserted into the alignment hole 21, and the secondary pin 122 is used to be inserted into the mounting hole 101, which can realize the detection of the positioning pin 102 of the whole product 100 with tolerance; correspondingly, the detection device of this utility model also includes a screw hole detection component 14; the screw hole detection component 14 can be inserted into the screw hole of the whole product 100, thereby detecting the position and depth of the screw hole.

[0047] For the use of the stop pin detection module 1, please refer to [reference needed]. Figure 4 , Figure 5 and Figure 9 As shown, the hole size detection component 11 is inserted into the mounting hole 101 to detect the size of the mounting hole 101 of the complete product 100. The pin size detection component 13 is inserted into the positioning pin 102 of the complete product 100 to detect the size of the positioning pin 102 of the complete product 100. More specifically, in this embodiment, the outer diameter tolerance of the through pin head 111 and the stop pin head 112 is ≤0.02mm; the hole diameter tolerance of the through pin hole 131 and the stop pin hole 132 is ≤0.02mm. For example, the inspection items for whether the complete product 100 is qualified include whether the main and auxiliary locating pins 102, mounting holes 101, and screw holes are qualified. Based on the analysis and calculation of the standard tolerance dimensions of the complete product 100 drawings, hole size inspection parts 11 and pin size inspection parts 13 are designed to clarify the standard for judging the dimensional tolerance range of mounting holes 101 and locating pins 102, and to clarify the standard for judging the position range of holes / pins by designing inspection pins. At the same time, it is also based on the standard tolerance of the complete product 100, with a tightening of 0.02mm to avoid errors caused by processing and manufacturing that may lead to misjudgment of the product. Specifically, the pin tolerance is as follows: Complete product... The lower tolerance of the diameter of the locating pin 102 of product 100 is +0.02mm / 0mm, and the upper tolerance of the diameter of the mounting hole 101 of product 100 is 0mm / -0.02mm; the tolerance of the through pin is: the upper tolerance of the diameter of the locating pin 102 of product 100 is 0mm / -0.02mm, and the lower tolerance of the diameter of the mounting hole 101 of product 100 is +0.02mm / 0mm; the tolerance of the hole position detection pin is: the lower limit tolerance of the combined dimension of the mounting hole 101 of product 100 is +0.02mm / 0mm; the upper limit tolerance of the combined dimension of the hole position detection component 12 of product 100 is 0mm / -0.02mm.

[0048] The reference positioning detection module 2 of this utility model is understood as a component having a calibrated support surface 22, capable of supporting the entire product 100 and fitting against the reference surface 103 of the entire product 100. Specifically, refer to... Figure 10 and Figure 3 As shown, the reference positioning detection module 2 includes at least one support surface 22; the support surface 22 can abut against the reference surface 103 of the whole product 100, and together with the plug 23, it can determine whether the reference surface 103 is flat. The reference positioning detection module 2 can provide support and positioning for the whole product 100. Based on the analysis and calculation of the reference positioning tolerance dimensions of the whole product 100, and with the design of the plug 23, alignment hole 21, and mounting hole 101 position detection component 12, the judgment range of the positions of the reference, positioning pin 102, and mounting hole 101 is clearly defined. It also serves to fix the whole product 100 and strengthens control based on the standard tolerance of the whole product 100, avoiding errors caused by processing and manufacturing that could lead to misjudgment of the product. Specifically: Plug 23 Tolerance: Thickness is the sum of the upper and lower tolerances of a reference standard dimension defined for the whole product 100, 0mm / -0.05mm; Main alignment hole 21 tolerance: Upper limit tolerance of the combined diameter dimension of the locating pin 102 on a reference surface of the whole product 100, 0mm / -0.02mm; Secondary alignment hole 21 tolerance: Upper limit tolerance of the combined diameter dimension of the reference locating pin 102 in the long and short directions of the whole product 100C, 0mm / -0.02mm; Alignment hole 21: Lower diameter tolerance of the hole position detection component 12, +0.02mm / 0mm.

[0049] The flip-position module 4 of this utility model can be understood as a structure that can close and abut against the three-dimensional curved screen 104. Specifically, as shown in the figure... Figure 11 and Figure 2 As shown, the flip positioning module 4 includes a rotating arm 41 and a contour block 42, which can facilitate the placement of the whole product 100. Several horizontally arranged flip modules in the flip module are designed with contour blocks 42 to fix the screen surface of the whole product 100. The contour blocks 42 can abut against the surface of the three-dimensional curved screen 104, clearly defining the range of the three-dimensional curved screen 104 of the whole product 100. After the flip module is opened, there is also a limiting block designed to fix the rotating arm 41 in the open state, providing operating space for the inspection personnel, facilitating the placement of the whole product 100, and performing the next intuitive inspection action.

[0050] The curved screen detection module 3 of this utility model is understood as a combined component that assists in detecting whether the surface contour of the three-dimensional curved screen 104 of the complete product 100 meets the product standard requirements. In the cooperating state of the closed flip-position module 4, the curved screen detection module 3 can be inserted into the gap between the contour block 42 of the flip-position module 4 and the three-dimensional curved screen 104 of the complete product 100, thereby realizing the contour detection of the curved screen. Specifically, refer to... Figure 12 and Figure 13 As shown, the curved screen detection module 3 includes multiple ball head detection components 31. Each ball head detection component 31 has a through ball head 311 and a stop ball head 312 at its two ends. The through ball head of each ball head detection component 31 is of equal size. The stop ball heads 312 of the multiple ball head detection components 31 decrease in size one by one, and the largest stop ball head 312 is ≥0.5mm larger than the through ball head. More specifically, the stop ball heads 312 of the multiple ball head detection components 31 decrease in size one by one with a tolerance of 0.5mm.

[0051] Specifically, the curved screen detection module 3 of this utility model clearly defines the standard for whether the surface profile of the three-dimensional curved screen 104 of the complete product 100 is qualified. It designs a 0.5mm gradient to define the upper and lower tolerance dimensions of the standard surface profile of the three-dimensional curved surface. The ball head detection component 31 of the curved screen detection module 3 is divided into multiple detection ball heads as the gradient detection range standard. Through multiple ball heads of different sizes, a more precise position can be defined as the current surface profile of the complete product 100 within the qualified range. Simultaneously, based on the upper and lower limits, a through ball head 311 and a stop ball head 312 are designed, which can intuitively determine whether the three-dimensional curved surface of the complete product 100 is qualified. The extreme ball heads are based on the standard tolerance of the three-dimensional curved surface of the complete product 100. A 0.02mm tightening is implemented to avoid errors caused by processing and manufacturing, which could lead to misjudgment of the entire product. Specifically: Tolerance of the through ball head 311: The tolerance on the three-dimensional curved surface of the entire product is the ball head diameter +0.05mm / 0mm; Tolerance of the stop ball head 312: The tolerance on the three-dimensional curved surface of the entire product is the ball head diameter 0mm / -0.05mm; Gradient tolerance of the ball head diameter of multiple ball head inspection components 31: The ball head diameter tolerance within the three-dimensional curved surface range of the entire product is ±0.05mm. Following the above methods and steps, without adjusting the parameters of the testing tools, inexperienced personnel can quickly start inspecting and judging whether the product is qualified and output an inspection report.

[0052] It should be noted that the screw hole detection component 14 of your utility model is understood to be able to be inserted into the screw holes of the complete product 100 to determine whether the depth and position design of the screw holes of the complete product 100 is qualified. For details, please refer to... Figure 1 and Figure 10 As shown, the screw hole detection component 14 is set as a screw hole detection pin. If the screw hole detection pin can be inserted into the screw hole and reach the set depth, the screw hole design is deemed qualified. If the screw hole detection pin cannot be inserted into the screw hole or the insertion depth is not reached, the screw hole design is deemed unqualified.

[0053] How this utility model is used:

[0054] In the first step, the hole size detection component 11, pin size detection component 13, and screw hole detection component 14 of the stop pin detection module 1 visually inspect and determine the mounting hole 101, locating pin 102, and screw hole of the complete product 100. If one end of the stop pin of each detection component cannot be inserted, and the pass pin of each detection component can be inserted, it means that the mounting hole 101, main and auxiliary locating pins 102, and screw hole of the complete product 100 are within the standard dimensional tolerance range of the complete product 100, indicating that the complete product is qualified.

[0055] The second step is to open the flip positioning module 4, place the whole product 100 on the support surface of the reference positioning module, observe whether each reference surface 103 of the whole product 100 is attached to the support surface 22 of the reference positioning module, and then use the plug 23 to check. If the plug 23 cannot be inserted into the gap between the reference surface 103 and the support surface 22, it is determined that each reference of the whole product 100 is within the standard dimensional tolerance range, indicating that the whole product is qualified.

[0056] The third step is to close and flip the positioning module 4 and fix the whole product 100. Use the hole position detection device to insert the mounting hole 101 and the alignment hole 21. If the hole position detection device 12 can be inserted, it is determined that the position of the mounting hole 101 of the whole product 100 is within the standard dimensional tolerance range, indicating that the whole product is qualified.

[0057] The fourth step involves using a ball-end testing piece 31 to test the gap between the three-dimensional curved screen 104 and the contour block 42 of the complete product 100. If the ball-end limit cannot be inserted into the gap, but the ball-end limit can, it indicates that the surface profile of the three-dimensional curved screen 104 of the complete product 100 is within the standard dimensional tolerance range, indicating that the complete product is qualified. The fifth step involves determining that the surface profile of the three-dimensional curved screen 104 of the complete product 100 is within the standard dimensional range. Ball-end testing pieces 31 with different gradients are used to test according to the description in the fourth step. If the ball-end limit ball-end of one of the ball-end testing pieces 31 can be inserted, the size of the ball-end limit ball-end of the ball-end testing piece 31 is recorded as the surface profile value of the three-dimensional curved screen 104. The surface profile value is within 0.5mm, which is beneficial for further detailed analysis of relevant data.

[0058] Step 6: Push the screw hole test piece 14 into the screw hole of the complete product 100. If it can be inserted normally into the screw hole, it means that the position and depth of the screw hole of the complete product 100 are within the standard dimensional tolerance range, indicating that the complete product is qualified.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
