Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a device for inspecting the application of automotive door handles. Background Technology

[0002] In the automotive manufacturing process, components such as touch-sensitive silicone pads and foam are often installed on car door handles. Touch-sensitive silicone pads are typically used in car door handles with keyless entry systems. As a cover layer for the touch sensor, they not only need to have sensitive touch response capabilities but also meet requirements for anti-slip, waterproof, and weather-resistant properties. The high elasticity and resistance to high and low temperatures of silicone allow it to adapt to various climatic conditions while enhancing friction to prevent slippage during operation. Foam is mainly used for cushioning, shock absorption, and sealing against dust. At the contact point between the door handle and the door panel, foam absorbs the impact force when closing the door, reducing noise from metal-on-metal collisions and improving the vehicle's quietness.

[0003] In traditional automotive production lines, the installation of door handle components is often done manually, which carries the risk of omissions and leads to production quality defects. Therefore, there is a need for technologies to inspect the installation of door handles.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In the automotive manufacturing process, components such as touch-sensitive silicone pads and foam are often installed on car door handles. Touch-sensitive silicone pads are typically used in car door handles with keyless entry systems. As a cover layer for the touch sensor, they not only need to have sensitive touch response capabilities but also meet requirements for anti-slip, waterproof, and weather-resistant properties. The high elasticity and resistance to high and low temperatures of silicone allow it to adapt to various climatic conditions while enhancing friction to prevent slippage during operation. Foam is mainly used for cushioning, shock absorption, and sealing against dust. At the contact point between the door handle and the door panel, foam absorbs the impact force when closing the door, reducing noise from metal-on-metal collisions and improving the vehicle's quietness.

[0028] In traditional automotive production lines, the installation of door handle components is often done manually, which carries the risk of omissions and leads to production quality defects. Therefore, there is a need for technologies to inspect the installation of door handles. Currently, the inspection of door handle installation mainly relies on visual inspection by management personnel, which is inefficient, labor-intensive, and impractical.

[0029] Moreover, this manual inspection method makes it difficult to integrate and collect relevant data, which makes subsequent traceability and analysis difficult. Furthermore, in some special cases, foam and other mounting components may be compressed during turnover or have quality problems, resulting in low actual usability. Manual inspection can only check whether they are installed or not, and cannot conduct targeted inspections for such special cases.

[0030] In view of this, this application provides an installation and testing device for automotive door handles, comprising: a housing, a product mounting slot, a slide rail, a first limiting block, a second limiting block, a detection structure, a positioning sensor, a distance sensor, an indicator light, and a microprocessor; the product mounting slot and the slide rail are disposed above the housing, the product mounting slot being located at one end of the slide rail, and the product mounting slot being used to install the automotive door handle product to be tested; the detection structure is movable along the slide rail, the first limiting block being used to limit the maximum distance the detection structure can slide towards the product mounting slot, and the second limiting block being used to limit the maximum distance the detection structure can slide away from the product mounting slot; the positioning sensor is disposed at the position corresponding to when the detection structure slides to the first limiting block, the distance sensor is disposed on the detection structure, and when the detection structure slides to the first limiting block, the distance sensor is located directly above the predetermined installation position of the automotive door handle product to be tested; the indicator light is disposed on the side of the housing; the microprocessor is connected to the positioning sensor, the distance sensor, and the indicator light.

A microprocessor analyzes the data in real time and provides feedback via indicator lights. Compared to manual inspection, this application significantly improves inspection efficiency and accuracy, reduces labor costs, avoids subjective errors, and ensures consistent production quality, making it suitable for large-scale application in automotive production lines.

[0031] The following is a detailed description of an automotive door handle mounting and testing device provided in the embodiments of this application, with reference to the specific accompanying drawings.

[0032] This application provides an installation and testing device for automotive door handles. Specifically, refer to... Figure 1 The automotive door handle mounting and testing equipment provided in this application embodiment mainly includes:

[0033] 1. Outer shell; 2. Product mounting slot; 3. Slide rail; 4. First limit block; 5. Second limit block; 6. Detection structure; 7. Position sensor; 8. Distance sensor; 9. Indicator light; and 10. Microprocessor.

[0034] The product mounting slot 2 and the slide rail 3 are disposed above the housing 1. The product mounting slot 2 is located at one end of the slide rail 3 and is used to mount the car door handle product 10 to be tested. The detection structure 6 is movable along the slide rail 3. The first limiting block 4 is used to limit the detection structure 6 to slide a maximum distance closer to the product mounting slot 2, and the second limiting block 5 is used to limit the detection structure 6 to slide a maximum distance away from the product mounting slot 2. The positioning sensor 7 is disposed at the position corresponding to when the detection structure 6 slides to the first limiting block 4. The distance sensor 8 is disposed on the detection structure 6, and when the detection structure 6 slides to the first limiting block 4, the distance sensor 8 is located directly above the predetermined mounting position of the car door handle product 10 to be tested. The indicator light 9 is disposed on the side of the housing 1.

[0035] The microprocessor is connected to the position sensor 7, the distance sensor 8, and the indicator light 9.

[0036] In this embodiment of the application, an installation detection device for car door handles is provided. The installation detection device adopts a sliding rail 3-type moving detection structure 6, combined with a position sensor 7 and a distance sensor 8, to accurately scan the installation position (such as silicone pad 11, foam 12) of the car door handle product 10. The microprocessor analyzes the data in real time and feeds back the results through an indicator light 9.

[0037] Specifically, in this embodiment, the automotive door handle mounting and testing equipment includes a housing 1, a product mounting groove 2, a slide rail 3, a first limiting block 4, a second limiting block 5, a detection structure 6, a positioning sensor 7, a distance sensor 8, an indicator light 9, and a microprocessor. The housing 1 can be made of metal or plastic, and its overall shape is a trapezoidal prism: the top and bottom surfaces are rectangular, the two sides are trapezoidal, and the front and rear sides are rectangular, with the front side angled and the rear side potentially perpendicular to the bottom surface. The housing 1 serves as the main frame of the mounting and testing equipment, providing a mounting base and protection for other components, ensuring the stability and safety of the overall structure.

[0038] In this embodiment, the product mounting slot 2 and the slide rail 3 are located above the housing 1, forming the core area for the testing operation. Specifically, the product mounting slot 2 is located at one end of the slide rail 3, specifically for fixing the car door handle product 10 to be tested. Installing the car door handle product 10 in the product mounting slot 2 ensures accurate and stable door handle positioning during testing, avoiding testing errors caused by displacement. The slide rail 3 serves as the moving track for the testing structure 6, allowing the testing structure 6 to slide along its length. The first limiting block 4 and the second limiting block 5 are respectively located at two positions on the slide rail 3 to limit the sliding range of the testing structure 6. The first limiting block 4 prevents the testing structure 6 from getting too close to the product mounting slot 2, avoiding collisions with the car door handle product 10; the second limiting block 5 limits the testing structure 6 to the furthest position away from the product mounting slot 2, ensuring controllable testing stroke. The first limiting block 4 and the second limiting block 5 can be located on the same side of the slide rail 3 or on different sides of the slide rail 3; this application does not impose any restrictions on this.

[0039] The detection structure 6 is the core component for performing the detection function. It can move along the slide rail 3, and a distance sensor 8 can be installed on top of it. As the detection structure 6 moves along the slide rail 3, the distance sensor 8 can be moved to the position of the car door handle product 10 in the product mounting slot 2. Specifically, in this embodiment, the positioning sensor 7 is installed at the corresponding position when the detection structure 6 slides to the first limit block 4. It is used to confirm whether the detection structure 6 has reached the preset detection starting point. Its signal can be used to trigger the microprocessor to start data acquisition, ensuring the synchronization and accuracy of the detection action. Furthermore, when the detection structure 6 moves to the first limit block 4, the distance sensor 8 is exactly above the predetermined mounting position of the car door handle product 10 to be tested. The distance sensor 8 can measure the distance to the predetermined mounting position, thereby determining whether the relevant mounting components (such as silicone pad 11 or foam 12) exist or whether the mounting conforms to the standard.

[0040] In terms of circuit structure, the microprocessor in this embodiment is connected to the position sensor 7, distance sensor 8, and indicator light 9. The microprocessor can be located inside the housing 1. From the perspective of circuit operation, in this embodiment, the microprocessor acts as the control center, connected to the position sensor 7, distance sensor 8, and indicator light 9. It is responsible for receiving the sensing signals from the position sensor 7 and distance sensor 8 and controlling the display status of the indicator light 9. Specifically, the detection structure 6 slides on the slide rail 3. When it slides to the first limit block 4, the position sensor 7 can detect the sensing signal and send it to the microprocessor. At this time, the microprocessor will collect the distance data measured by the distance sensor 8 and determine whether a compliant component is installed at the predetermined mounting position of the car door handle product 10 based on the distance data.

[0041] It is easy to understand that if a compliant component is installed at the predetermined mounting position of the car door handle product 10, the distance data measured by the distance sensor 8 will be the distance between the distance sensor 8 and the installed component. The thickness range of the compliant installed component is fixed, so the distance data will normally be within a certain range. If there is no installed component at the predetermined mounting position of the car door handle product 10 or the installed component has quality defects (such as the foam 12 being flattened), the distance data measured by the distance sensor 8 will be the distance between the distance sensor 8 and the product mounting groove 2, which will obviously be greater than the distance data measured under normal circumstances. Therefore, through this characteristic, the microprocessor can determine whether the installation of the car door handle is compliant. For example, the microprocessor can be equipped with a related comparator circuit, which is preset with circuit parameters (such as current or voltage) corresponding to the distance data under normal circumstances. By comparing the circuit parameters corresponding to the distance data measured by the distance sensor 8, it can be determined whether the installation of the car door handle is compliant.

[0042] In this embodiment, the microprocessor determines whether the installation of the car door handle is compliant, which can be used to control the operation of the indicator light 9, which can be an LED light. For example, in some embodiments, if the installation of the car door handle is compliant, the indicator light 9 can light up, and if it is not compliant, the indicator light 9 will not light up; or, if it is compliant, it can light up green, and if it is not compliant, it can light up red, etc. This application does not limit this.

[0043] It is understood that the automotive door handle mounting inspection device provided in this application embodiment improves upon the problems of low efficiency and high missed detection rate of traditional manual visual inspection through automated inspection. This mounting inspection device adopts a sliding rail 3-type moving inspection structure 6, combined with a position sensor 7 and a distance sensor 8, to accurately scan the mounting position (such as silicone pad 11, foam 12) of the automotive door handle product 10. A microprocessor analyzes the data in real time and provides feedback through an indicator light 9. Compared with manual inspection, this application can significantly improve inspection efficiency and accuracy, reduce labor costs, and avoid subjective errors, ensuring consistent production quality. It is suitable for large-scale application in automotive production lines.

[0044] Specifically, in some embodiments, the mounting detection device further includes a power supply 13, which is disposed inside the housing 1. The power supply 13 is used to power the positioning sensor 7, the distance sensor 8, the indicator light 9, and the microprocessor. The voltage level of the power supply 13 can be 220V or other levels, and this application does not limit it.

[0045] Specifically, in some embodiments, the mounting inspection equipment further includes a stepper motor 14, which drives the inspection structure 6 to slide on the slide rail 3. In this embodiment, the stepper motor 14 can receive control signals from the microprocessor to move the inspection structure 6 with a preset step size and speed, ensuring its positioning accuracy and motion stability on the slide rail 3. The start, stop, and direction of the stepper motor 14 can be controlled in real time by the microprocessor, enabling it to work in conjunction with the positioning sensor 7 and the distance sensor 8, accurately stopping when it reaches the first limit block 4 and resetting after completing the inspection, thereby forming a closed-loop control system and further improving the automation level of the mounting inspection equipment.

[0046] Specifically, in some embodiments, the mounting inspection device further includes a display screen 15, which is connected to the microprocessor and is disposed on the same side as the indicator light 9.

[0047] In this embodiment, a display screen 15 can be added to the mounting inspection equipment. The display screen 15 can be connected to a microprocessor and mounted on the surface of the housing 1 on the same side as the indicator light 9. The display screen 15 can display more detailed inspection data in real time, such as distance measurements, mounting deviations, and inspection result statistics. It can also provide interactive content such as operation guidance and equipment status. Compared to simple status indication via the indicator light 9 alone, the addition of the display screen 15 significantly enhances the richness and intuitiveness of human-machine interaction, enabling operators to quickly understand the inspection results and obtain more comprehensive process data, facilitating quality traceability and problem analysis. The display screen 15 and the indicator light 9 work together to form a multi-layered feedback system, retaining the immediacy of light prompts while increasing the depth of data visualization, further optimizing the operational experience and information management efficiency of the inspection process.

[0048] Specifically, in some embodiments, the mounting detection device further includes a buzzer 16, which is connected to the microprocessor and is located on the same side as the indicator light 9.

[0049] In this embodiment, the placement inspection equipment is also equipped with a buzzer 16, which is connected to the microprocessor and mounted on the surface of the housing 1 on the same side as the indicator light 9 and the display screen 15. When an abnormality is detected (such as missing components or unqualified placement), the buzzer 16 will emit a warning sound, forming a dual sound and light alarm system with the visual signal from the indicator light 9. This design significantly improves the immediate perception of abnormalities, ensuring that quality problems are detected and handled promptly even in noisy production environments or when operators are not directly focused on the placement inspection equipment.

[0050] Specifically, in some embodiments, the mounting inspection device further includes a communication module 17, which is connected to the microprocessor and is used to communicate with an external host computer.

[0051] In this embodiment, the mounting inspection equipment can further integrate a communication module 17. This communication module 17 is directly connected to the microprocessor, enabling real-time data interaction between the equipment and an external host computer system. Through wired (e.g., RS485, Ethernet) or wireless (Wi-Fi, 4G) communication methods, the communication module 17 can upload key information such as inspection data and equipment status to the external host computer, achieving electronic traceability and centralized management of the inspection data. Exemplarily, the communication module 17 may include a Wi-Fi module, Bluetooth module, Zigbee module, or LoRa module, but is not limited to these.
