Description

Technical Field

[0001] This application relates to the technical field of automotive parts testing technology, and in particular to a quality testing device for automotive logos. Background Technology

[0002] As a crucial identifier for vehicles, car logos typically integrate integrated lighting units. When illuminated, these units clearly display the brand logo, enhancing the vehicle's aesthetics and nighttime visibility. Quality inspection is a critical step in the logo production process to ensure product reliability. Brightness testing is essential to verify that the logo's illumination is sufficient and evenly distributed, guaranteeing a clear and complete display of the logo and preventing areas of dimness or blurring that could negatively impact visual appeal. Airtightness testing is equally important, as the logo is installed on the vehicle's exterior and is constantly exposed to rain, dust, and other pollutants. Poor airtightness allows external moisture and dust to penetrate the light, causing fogging or dust accumulation. This not only damages the logo's appearance but can also lead to electrical malfunctions or premature aging of the light fixture, shortening its lifespan.

[0003] Currently, the commonly used testing equipment in the industry separates brightness testing and airtightness testing. For example, brightness parameters are first measured using a light illuminance testing device, and then an airtightness tester is used to check the sealing effect. This batch testing method requires multiple operations and workstation changes, increasing the number of testing steps and time consumption, and reducing overall work efficiency. Utility Model Content

[0004] To address the problem of low inspection efficiency caused by multiple operations and station changes required in existing automotive emblem quality inspection technologies, this application provides a quality inspection device for automotive emblems.

[0005] The technical solution of the quality inspection device for automobile emblems provided in this application is as follows: A quality inspection device for automotive emblems includes a support frame, an airtightness testing component, a display component, and a brightness detection probe. The airtightness testing component includes a push cylinder, a venting cylinder, and an air pump. The push cylinder is mounted on the support frame, and the venting cylinder is mounted on the piston rod of the push cylinder. An air outlet is provided at the end of the venting cylinder. The air pump is mounted on the support frame, and an air pipe connects the air pump to the venting cylinder. A detection sensor is mounted on the air pump. The brightness detection probe is mounted on the support frame. The display component includes a display and an information processor. The display is mounted on the support frame, and the information processor is mounted on the display. The brightness detection probe is communicatively connected to the information processor. The detection sensor is communicatively connected to the information processor.

[0006] By adopting the above technical solution, this system achieves simultaneous detection of the airtightness and brightness of automotive logos through the installation of an airtightness detection component and a brightness detection probe, which are communicatively connected to the display component. The support frame provides a stable mounting foundation and working platform for the entire detection device. The push cylinder precisely drives the venting cylinder to align with the logo detection hole, while the air pump supplies air to the venting cylinder through an air pipe. The detection sensor monitors gas pressure changes in real time, completing the automatic airtightness detection. The brightness detection probe collects the brightness parameters of the internal lighting assembly of the logo. The display and information processor work together to visualize the detection data, allowing operators to intuitively read the results and effectively improving detection efficiency and accuracy.

[0007] Preferably, the airtightness testing assembly further includes an airtightness testing support rod and a first connecting frame, the push cylinder is vertically mounted on the support frame; the airtightness testing support rod is rotatably mounted on the piston rod of the push cylinder, one end of the first connecting frame is rotatably mounted on the push cylinder, and the other end of the first connecting frame is rotatably mounted on the airtightness testing support rod; the vent is mounted on the airtightness testing support rod.

[0008] By adopting the above technical solution, this solution transforms the linear motion of the driving cylinder into the swing motion of the venting cylinder through the rotational connection of the air tightness testing support rod and the first connecting frame, ensuring accurate alignment between the venting cylinder outlet and the vehicle logo testing hole, thereby improving the automation level and alignment reliability of the air tightness test.

[0009] Preferably, the support frame is provided with a support plate, and the support plate is provided with a support for supporting the vehicle logo.

[0010] By adopting the above technical solution, a dedicated bearing position for the car logo is provided by setting a support on the support plate. The support ensures the stability of the car logo during the inspection process, avoiding inspection errors caused by unstable support, and providing a reliable reference plane for subsequent inspection items.

[0011] Preferably, the upper end of the support is provided with a positioning groove, which is used to position the vehicle logo.

[0012] By adopting the above technical solution, a rapid positioning mechanism is formed through the cooperation between the positioning groove on the support and the car logo connecting ear. This design allows the car logo to be quickly and accurately installed on the inspection station, reducing manual adjustment time and preventing horizontal displacement of the car logo during inspection, thus ensuring the stability of the inspection process.

[0013] Preferably, the support frame is further provided with a detection cover, which is located below the support plate. The support plate has a through hole for extending the indicator light part of the car logo into the detection cover. The brightness detection probe is located on the inner bottom wall of the detection cover, and the detection end of the brightness detection probe faces the through hole.

[0014] By adopting the above technical solution, the combination of the detection cover and the through-hole design creates a closed detection environment for brightness detection. The detection cover effectively isolates external light interference, while the through-hole allows the vehicle logo indicator light to extend into the detection cover. The brightness detection probe performs brightness measurement under ideal conditions, improving the accuracy of the detection data.

[0015] Preferably, the support frame is provided with a positioning assembly, which includes a positioning cylinder, a positioning support rod, a second connecting frame, and a positioning rod. The positioning cylinder is vertically mounted on the support plate, and the end of the positioning support rod is rotatably mounted on the piston rod of the positioning cylinder. One end of the second connecting frame is rotatably mounted on the positioning cylinder, and the other end of the second connecting frame is rotatably mounted on the positioning support rod. The positioning rod is mounted on the positioning support rod, and the end of the positioning rod is provided with a pressing block. The positioning assembly is used to press the car emblem onto the support.

[0016] By adopting the above technical solution, the positioning component utilizes a multi-link mechanism design to achieve flexible movement of the clamping block. The positioning cylinder drives the positioning support rod to swing, which in turn causes the clamping block at the end of the positioning rod to apply a load to the car emblem, ensuring the emblem remains stable during inspection and providing the necessary fixing conditions for precision inspection.

[0017] Preferably, the positioning assembly further includes a mounting nut for positioning the positioning rod on the positioning support rod.

[0018] By adopting the above technical solution, a reliable connection between the positioning rod and the positioning support rod is achieved through the locking mechanism of the mounting nut. The mounting nut uses a mechanical locking method to ensure that the positioning rod maintains a stable position during the testing process, preventing loosening due to vibration or external force, and improving the overall rigidity and operational reliability of the positioning assembly.

[0019] Preferably, the support frame is further provided with a missing part detection probe, which is disposed on the support frame and located above the support plate.

[0020] By adopting the above technical solution, the missing parts detection probe is installed above the support frame with its detection end facing the logo fixing station, enabling automatic verification of the completeness of parts assembly after the logo is positioned. This probe establishes a communication connection with the information processor, transmitting the detection data to the display component in real time, allowing operators to simultaneously obtain the missing parts detection results. This design enables specialized detection of missing logo parts, avoiding quality defects caused by missing parts and improving the comprehensiveness of the inspection.

[0021] Preferably, the support frame is further provided with a marking assembly, the marking assembly including a marking cylinder, the marking cylinder being disposed on the support frame, and the piston rod of the marking cylinder being provided with a marking rod; the marking assembly is used to mark the qualified vehicle logo.

[0022] By adopting the above technical solution and setting up the marking component, automatic identification of qualified products is achieved. The marking cylinder drives the marking rod to apply a mark to the qualified vehicle label, establishing a connection between inspection and sorting, which facilitates product classification and quality traceability in subsequent processes.

[0023] In summary, this application includes the following beneficial technical effects: Through integrated design, multiple testing functions are consolidated into a single workstation. The support frame serves as the basic support structure, providing a stable mounting platform for each testing component. The positioning component reliably secures the logo to the support using clamping blocks, ensuring the logo's position remains stable during testing. The airtightness testing component uses a cylinder to drive a vent pipe to precisely align with the logo's testing hole; an air pump provides the testing air source, and a testing sensor monitors pressure parameters in real time, enabling automatic airtightness testing. The brightness testing probe measures brightness within the enclosed environment created by the testing hood, avoiding ambient light interference. A missing component testing probe verifies the integrity of the logo parts. The display component centrally displays all testing data, facilitating quick product quality assessment by operators. The marking component identifies qualified products, seamlessly integrating testing and sorting. The collaborative work of these components allows for multiple tests to be completed in a single logo clamping operation, significantly reducing testing steps and time costs, and improving production efficiency and testing reliability.

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a quality inspection device for automobile emblems, referring to... Figures 1-3 The system includes a support frame 1, an airtightness testing component 3, a display component 5, and a brightness testing probe 6. A positioning component 2 and a missing component detection probe 4 are mounted on the support frame 1. The support frame 1 supports the positioning component 2, the airtightness testing component 3, the missing component detection probe 4, the display component 5, and the brightness testing probe 6. The airtightness testing component 3 is used to test the airtightness of the vehicle logo 8, and the brightness testing probe 6 is used to test whether the lighting assembly inside the vehicle logo 8 meets the standards. The airtightness testing component 3 and the brightness testing probe 6 are communicatively connected to the display component 5, which displays the results detected by the airtightness testing component 3 and the brightness testing probe 6. The positioning component 2 is used to press the vehicle logo 8 firmly onto the support frame 1. The missing component detection probe 4 is used to detect whether the vehicle logo 8 is missing any parts.

[0033] Reference Figures 1-3A support plate 11 is fixedly connected to the support frame 1, which forms the base platform of the inspection station. A support 111 for supporting the car logo 8 is fixedly connected to the upper top wall of the support plate 11. To stably support and accurately position the car logo 8, this embodiment provides two sets of supports 111. These two supports 111 are symmetrically arranged about a through hole 112 in the center of the support plate 11. Connecting ears 82 are provided on opposite sides of the car logo 8 body. Correspondingly, each support 111 has a positioning groove 1111 at its upper end that matches the shape of the connecting ear 82. When installing the car logo 8, the connecting ears 82 on both sides of the car logo 8 must be precisely embedded into the positioning grooves 1111 of the corresponding supports 111. This mating structure composed of the connecting ears 82 and the positioning grooves 1111 forms a rapid positioning and limiting mechanism. This device can achieve rapid initial positioning of the logo 8, effectively preventing the logo 8 from moving in the horizontal plane during subsequent pressing or testing, and providing a stable and reliable support benchmark for airtightness testing and brightness testing.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The positioning assembly 2 is installed on the support plate 11. Two sets of positioning assemblies 2 are provided, each set located on one side of a support 111. This embodiment uses one set of positioning assemblies 2 as an example. The positioning assembly 2 includes a positioning cylinder 21, a positioning support rod 22, a second connecting frame 23, a positioning rod 24, and a mounting nut 25. The positioning cylinder 21 is vertically fixed to the upper top wall of the support plate 11. The end of the positioning support rod 22 is rotatably connected to the end of the piston rod of the positioning cylinder 21. One end of the second connecting frame 23 is rotatably connected to the upper end of the positioning cylinder 21, and the other end of the second connecting frame 23 is rotatably connected to the positioning support rod 22. The positioning rod 24 is installed on the positioning support rod 22 via the mounting nut 25. One end of the positioning rod 24 is fixedly connected to a clamping block 241. Specifically, the end of the positioning support rod 22 away from the positioning cylinder 21 has a mounting hole, and the axis of the mounting hole is perpendicular to the long axis of the positioning support rod 22. The other end of the positioning rod 24 passes through the mounting hole until the clamping block 241 contacts the positioning support rod 22, and then the positioning rod 24 is positioned on the positioning support rod 22 by the mounting nut 25.

[0035] Reference Figures 2-4After the logo 8 is initially positioned by the connecting ear 82 and the positioning groove 1111 of the support 111, the positioning cylinder 21 is activated, driving the piston rod to extend and retract. The movement of the piston rod is converted into the swinging motion of the positioning support rod 22 through the rotational connection between the positioning support rod 22 and the second connecting frame 23. The positioning support rod 22 drives the positioning rod 24 to move, causing the clamping block 241 to contact and press against the connecting ear 82 of the logo 8. This process ensures that the logo 8 is firmly fixed during the inspection process, effectively preventing horizontal displacement, thereby providing a stable benchmark for airtightness and brightness inspection.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The airtightness testing assembly 3 includes a push cylinder 31, an airtightness testing support rod 32, a vent 33, a first connecting frame 34, and an air pump 35. The push cylinder 31 is vertically fixed to the support plate 11. The end of the airtightness testing support rod 32 is fixedly connected to the piston rod of the push cylinder 31. One end of the first connecting frame 34 is rotatably connected to the push cylinder 31, and the other end of the first connecting frame 34 is rotatably connected to the airtightness testing support rod 32. One end of the vent 33 is fixedly connected to the end of the airtightness testing support rod 32 away from the push cylinder 31, and the other end of the vent 33 has an air outlet 331. The axis of the vent 33 is perpendicular to the long axis of the airtightness testing support rod 32. The air pump 35 is fixedly connected to the support plate 11 and located on one side of the push cylinder 31. The air pump 35 is connected to the side wall of the vent 33 through an air pipe (not shown in the figure), and the air pump 35 inflates the vent 33 through this air pipe.

[0037] Reference Figure 2 , Figure 3 and Figure 6 After the car logo 8 is positioned on the support 111 by the positioning component 2, a detection hole 81 is opened on the side wall of the car logo 8 away from the support plate 11. The display component 5 includes a display 51 and an information processor 52. The display 51 is fixedly connected to the upper top wall of the support plate 11 by a pillar, and the information processor 52 is fixedly connected to the display 51. A detection sensor 351 is fixedly connected to the air pump 35, and the detection sensor 351 is communicatively connected to the information processor 52. The display 51 is used to display the airtightness test results.

[0038] Reference Figure 2 , Figure 3 and Figure 5The working process of the airtightness testing component 3 is as follows: After the car logo 8 is pressed onto the support 111 by the positioning component 2, the cylinder 31 is activated, driving the piston rod to extend and retract. The movement of the piston rod is converted into the swing of the airtightness testing support rod 32 through the rotational connection of the first connecting frame 34, thereby driving the vent cylinder 33 to move towards the detection hole 81 of the car logo 8, aligning the air outlet 331 of the vent cylinder 33 with the detection hole 81. The air pump 35 delivers gas to the vent cylinder 33 through the air pipe, and the gas enters the interior of the car logo 8 from the air outlet 331. The detection sensor 351 monitors the gas pressure change in real time and sends the pressure data to the information processor 52. The information processor 52 receives the pressure data from the detection sensor 351, analyzes and processes it, determines whether the airtightness of the car logo 8 meets the standard, and outputs the test result to the display 51. The operator can directly view the airtightness test result through the display 51, thereby quickly assessing the sealing performance of the car logo 8.

[0039] Reference Figure 1 , Figure 2 and Figure 6 A detection cover 12 is fixedly connected to the support frame 1. The detection cover 12 is located at the lower end of the support plate 11. The brightness detection probe 6 is fixedly connected to the inner bottom wall of the detection cover 12, with the detection end of the brightness detection probe 6 facing the through hole 112. The car logo 8 is pressed onto the support 111 by the positioning component 2, and the indicator light part of the car logo 8 extends into the detection cover 12. The detection cover 12 provides a closed environment for brightness detection, avoiding interference from external light. The brightness detection probe 6 measures the brightness of the indicator light. The brightness detection probe 6 is communicatively connected to the information processor 52 and transmits the detection data to the display 51 in real time. The display 51 displays the brightness detection results, and the operator can directly read the data to evaluate whether the light emitted by the car logo 8 is uniform and sufficient.

[0040] Reference Figure 1 and Figure 6 The support frame 1 is also fixedly connected to a missing part detection probe 4. The missing part detection probe 4 is located above the support plate 11, and the detection end of the missing part detection probe 4 faces the car logo 8. The missing part detection probe 4 is used to detect whether the car logo 8 has missing parts. The missing part detection probe 4 is connected to the information processor 52 for communication, and the display 51 is used to display the measurement results.

[0041] Reference Figures 1-2The support frame 1 is also equipped with a marking assembly 7, which includes a marking cylinder 71 and a marking bracket 73. The marking bracket 73 is vertically fixed to the upper top wall of the support plate 11, and the marking cylinder 71 is fixedly connected to the upper end of the marking bracket 73, with the axis of the marking cylinder 71 perpendicular to the long axis of the marking bracket 73. A marking rod 72 is provided on the piston rod of the marking cylinder 71. The marking assembly 7 is used to mark the qualified vehicle logo 8. Specifically, the end of the marking rod 72 is provided with a cone. When the vehicle logo 8 passes quality inspection and is deemed qualified, the marking cylinder 71 drives the marking rod 72 to move closer to the vehicle logo 8 via its piston rod, thereby leaving a mark on the vehicle logo 8.

[0042] The implementation principle of a quality inspection device for automobile emblems in this application is as follows: The car logo 8 is initially positioned by the engagement of the connecting ear 82 and the positioning groove 1111, and is then pressed and fixed by the clamping block 241 driven by the positioning component 2. After the logo 8 is fixed, brightness detection, missing part detection, and airtightness detection are performed simultaneously. The brightness detection probe 6 completes the brightness measurement inside the detection cover 12, the missing part detection probe 4 checks the integrity of the part assembly, and at the same time, the airtightness detection component 3 is inflated through the vent 33 and the pressure change is monitored by the detection sensor 351. The results of the three tests are simultaneously transmitted to the information processor 52 for analysis and are centrally displayed on the display 51. If all the test results are qualified, the marking component 7 marks the logo 8.

[0043] This application integrates multiple testing functions into a single workstation using an integrated support frame 1, positioning component 2, airtightness testing component 3, and brightness testing probe 6. This design eliminates the steps of transferring and repeatedly positioning workpieces between different testing devices, allowing all testing items to be completed in a single clamping operation. This effectively reduces testing procedures, shortens the total testing time for a single product, and thus improves overall work efficiency.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
