Description

Technical Field

[0001] This utility model relates to the field of automotive roof inspection technology, and more specifically, to an electrical inspection fixture for roof assemblies. Background Technology

[0002] In the automotive manufacturing industry, the headliner assembly, as a crucial interior component, integrates various lighting elements such as reading lights. The functionality and integrity of these components directly impact the vehicle's driving experience and safety performance. Currently, the industry's testing of headliner assembly lighting components still largely relies on manual operation: at the end of the production line or quality inspection station, operators must power on the headliner assembly via an external power source, then manually activate each lighting component one by one (such as pressing the reading light switch), and visually inspect whether the lights illuminate normally, whether the brightness is uniform, and whether there is any flickering or extinguishing, thereby determining whether the component is qualified.

[0003] This traditional inspection method has significant drawbacks: Firstly, it is extremely inefficient, especially in mass production scenarios. Each vehicle's headliner contains multiple lighting components, and manual inspection of each component is time-consuming, severely restricting production line speed. Secondly, the quality stability is poor; prolonged repetitive operations can lead to operator fatigue, potentially resulting in missed inspections or misjudgments (such as overlooking slight flickering or localized brightness anomalies). Furthermore, the inspection results are significantly influenced by subjective factors such as operator experience. In addition, with the increasing intelligence of automotive interiors, the integration of headliner lighting components is becoming more sophisticated, making it difficult for manual inspection to cover complex lighting logic control scenarios, further exacerbating the limitations of the quality inspection process. Utility Model Content

[0004] The technical problem to be solved by this application is that manual inspection is inefficient and inconsistent. In order to overcome the above-mentioned defects of the prior art, this application provides an electrical inspection fixture for roof assembly.

[0005] This application provides an electrical testing fixture for a roof assembly, comprising: The base has multiple support blocks on it, and the support blocks have contour grooves for positioning and matching the canopy assembly. The fixing mechanism includes a horizontal moving component, a vertical moving component, and a pressing block. The horizontal moving component is mounted on a base, the vertical moving component is mounted on the horizontal moving end of the horizontal moving component, and the pressing block is connected to the vertical moving end of the vertical moving component and moves with the horizontal moving component to the top of the roof assembly to press and fix the roof assembly onto the support block. A pressing mechanism is mounted on a base, with the pressing output end of the pressing mechanism facing the lighting switch on the ceiling assembly; An image acquisition unit, mounted on a base, is used to acquire the light emission signals from the lighting components on the roof assembly; The feedback component, mounted on the base, is used to provide feedback on whether the lighting components on the ceiling assembly are up to standard. The control component is electrically connected to the fixing mechanism, the pressing mechanism, the image acquisition component, and the feedback component, respectively.

[0006] Compared with existing technologies, the electrical inspection fixture for headliner assemblies disclosed in this application has the following advantages: precise positioning of the headliner assembly is achieved through the contoured groove of the base; the horizontal and vertical moving components of the fixing mechanism can flexibly adjust the position of the pressing block to achieve stable fixing of the automotive headliner; the pressing mechanism automatically triggers the lighting switch, cooperates with the image acquisition component to detect the lighting status, provides intuitive output results from the feedback component, and the control component coordinates the collaborative work of all mechanisms. This fixture completely replaces manual inspection, improving inspection efficiency, ensuring inspection consistency, avoiding human error, and is suitable for the inspection of highly integrated automotive headliner lighting components.

[0007] In one possible implementation, the horizontal moving assembly includes a moving frame, a horizontal push cylinder, and a sliding structure. The moving frame is horizontally connected to the base via the sliding structure. The cylinder body of the horizontal push cylinder is fixed to the base, and the telescopic rod of the horizontal push cylinder is connected to the moving frame. The vertical moving assembly includes a vertical push cylinder and a push frame. The cylinder body of the vertical push cylinder is fixedly connected to the moving frame, and the telescopic rod of the vertical push cylinder is connected to the push frame. The extrusion block is fixedly connected to the push frame. Compared with the prior art, the horizontal moving assembly drives the moving frame to move along the sliding structure via the horizontal push cylinder, and the vertical moving assembly drives the push frame via the vertical push cylinder to raise and lower the extrusion block, forming a two-stage drive structure of "horizontal position adjustment and vertical pressure application." This improves the flexibility and adjustment accuracy of the fixing mechanism, adapts to the fixing requirements of the ceiling, and the push cylinder drive response is rapid, further improving the detection cycle efficiency.

[0008] In one possible implementation, the sliding structure includes a slide rail and a slider. The slide rail is fixedly mounted on a base, the slider is slidably connected to the slide rail, and the movable frame is fixedly connected to the slider. Compared with the prior art, the cooperation between the slide rail and the slider provides stable horizontal guidance for the movable frame, reduces frictional resistance and offset errors during horizontal movement, ensures the smooth operation and positioning accuracy of the horizontal moving component, and indirectly improves the fixing reliability of the fixing mechanism for the car roof.

[0009] In one possible implementation, the extrusion block is a polyurethane block. Compared with the prior art, polyurethane has a certain degree of elasticity and wear resistance, which can not only firmly fix the roof assembly through extrusion, but also avoid hard materials from causing indentations or scratches on the roof surface, thus protecting the appearance integrity of the workpiece being tested.

[0010] In one possible implementation, the pressing mechanism includes a capacitive pressing head, a pressing cylinder, and a column. The column is fixedly mounted on a base, the cylinder body of the pressing cylinder is fixedly connected to the column, and the capacitive pressing head is connected to the telescopic rod of the pressing cylinder for moving toward the lighting switch on the ceiling assembly. Compared with the prior art, the capacitive pressing head can accurately simulate manual pressing action, and in conjunction with the pressing cylinder drive, it realizes automatic triggering of the ceiling lighting switch with high triggering accuracy; the fixed column ensures stable pressing direction, further improving the reliability and consistency of pressing action.

[0011] In one possible implementation, the image acquisition component is an industrial camera. Compared with existing technologies, industrial cameras have higher image resolution and anti-interference capabilities than ordinary cameras, and can clearly capture the luminous state of lighting components, providing accurate image data for the qualification determination of control components and reducing the risk of misjudgment.

[0012] In one possible implementation, the feedback component is a loudspeaker. Compared to existing technologies, the loudspeaker provides real-time feedback of detection results via sound signals, eliminating the need for operators to constantly monitor the visual display device. This allows for rapid transmission of results information within the production line environment, improving the convenience of the detection process.

[0013] In one possible implementation, the base is equipped with an anti-static fan for removing static electricity and an encoding collector for collecting the roof assembly code. Both the anti-static fan and the encoding collector are electrically connected to the control components. Compared with the prior art, the anti-static fan removes static electricity from the surface of the car roof, preventing static electricity from interfering with or damaging electronic lighting components; the encoding collector automatically records the roof assembly code, realizing a one-to-one correspondence between the detection results and the workpiece, facilitating subsequent traceability and quality statistics, and improving the precision of production quality management.

[0014] In one possible implementation, the base is provided with a forklift slot and adjustable height screw feet. Compared with the prior art, the forklift slot facilitates the overall handling and relocation of the tooling, adapting to the needs of production line layout adjustments; the adjustable height screw feet can adjust the level of the base, ensuring the stability and testing accuracy of the tooling under different ground conditions.

[0015] In one possible implementation, the fixture further includes a protective canopy positioned above the base, on which are mounted a lighting fixture, multi-layer warning lights, a display, and a camera, all electrically connected to the control components. Compared to existing technologies, the protective canopy provides protection for the testing area; the lighting fixture ensures stable lighting conditions when the car roof is installed; the multi-layer warning lights visually display the fixture's operating status; the display shows the testing results; and the camera records the testing process. This improves the fixture's safety, environmental adaptability, and monitorability, allowing operators to monitor the testing situation in real time. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 6 This application discloses an electrical testing fixture for a roof assembly, comprising: a base 1, a fixing mechanism 2, a pressing mechanism 3, an image acquisition component 4, a feedback component 5, and a control component. The base 1 is provided with multiple support blocks 11, and the support blocks 11 are provided with contour grooves for positioning and matching the ceiling assembly; the fixing mechanism 2 includes a horizontal moving component 21, a vertical moving component 22 and a pressing block 23. The horizontal moving component 21 is installed on the base 1, the vertical moving component 22 is installed on the horizontal moving end of the horizontal moving component 21, and the pressing block 23 is connected to the vertical moving end of the vertical moving component 22 and moves with the horizontal moving component 21 to the top of the ceiling assembly, pressing and fixing the ceiling assembly to the support blocks 11; the pressing mechanism 3 is installed on the base 1, and the pressing output end of the pressing mechanism 3 faces the lighting switch on the ceiling assembly; the image acquisition component 4 is installed on the base 1 and is used to acquire the light emission signal of the lighting component on the ceiling assembly; the feedback component 5 is installed on the base 1 and is used to output feedback on whether the lighting component on the ceiling assembly is qualified; the control component is electrically connected to the fixing mechanism 2, the pressing mechanism 3, the image acquisition component 4 and the feedback component 5 respectively.

[0022] The base 1 is welded from high-strength alloy steel to ensure the stability of the overall structure. On the upper surface of the base 1, multiple support blocks 11 are distributed at intervals according to the contour of the roof assembly. The top of each support block 11 is machined with a contoured groove that perfectly matches the shape of the bottom of the roof assembly. The support blocks 11 are made of nylon, which not only accurately positions the roof assembly but also prevents scratches on the roof surface during placement.

[0023] The working process of the fixing mechanism 2 is as follows: After the roof assembly is placed on the support block 11, the horizontal moving component 21 is activated first, driving the vertical moving component 22 and the pressing block 23 to move horizontally to the position to be fixed on the roof assembly. Subsequently, the vertical moving component 22 drives the pressing block 23 to move downward until the pressing block 23 fits tightly against the upper surface of the roof assembly, firmly fixing it in the contour groove of the support block 11.

[0024] The installation position of the pressing mechanism 3 corresponds to the position of the lighting switch on the ceiling assembly. During the testing phase, the pressing output end of the pressing mechanism 3 will move accurately toward the lighting switch and apply appropriate pressing force according to the instructions of the control component, simulating the action of manually pressing the switch to realize the opening or closing of the lighting component.

[0025] Image acquisition unit 4 is mounted on base 1, with its lens aimed at the light-emitting areas of all lighting components on the ceiling assembly. When the lighting components are turned on, image acquisition unit 4 immediately activates, acquiring the light emission signals from the lighting components, including parameters such as brightness, color, and flicker frequency, and transmitting these signals to the control unit. After analyzing and processing the signals, the control unit determines that the lighting components are qualified; if so, feedback unit 5 outputs a qualified signal; otherwise, it outputs a corresponding unqualified prompt.

[0026] The control unit uses a PLC controller, which establishes electrical signal connections with the fixing mechanism 2, pressing mechanism 3, image acquisition unit 4, and feedback unit 5 through a preset program. It can receive signals from the image acquisition unit 4, control the operation of the feedback unit 5 based on the analysis results, and coordinate the action sequence and timing of the fixing mechanism 2 and pressing mechanism 3 to achieve automated control of the entire detection process.

[0027] In this embodiment, the horizontal moving assembly 21 includes a moving frame 211, a horizontal push cylinder 212, and a sliding structure. The moving frame 211 is horizontally connected to the base 1 via the sliding structure. The cylinder body of the horizontal push cylinder 212 is fixed to the base 1, and the telescopic rod of the horizontal push cylinder 212 is connected to the moving frame 211. The vertical moving assembly 22 includes a vertical push cylinder 221 and a push frame 222. The cylinder body of the vertical push cylinder 221 is fixedly connected to the moving frame 211, and the telescopic rod of the vertical push cylinder 221 is connected to the push frame 222. The pressing block 23 is fixedly connected to the push frame 222.

[0028] Specifically, the moving frame 211 in the horizontal moving assembly 21 is a frame structure made of aluminum alloy to reduce its weight. A sliding structure enables the horizontal movement of the moving frame 211 to the base 1. The horizontal push cylinder 212 is a pneumatic push cylinder, its cylinder body fixed to the base 1 with bolts, and the end of the telescopic rod connected to the side of the moving frame 211 via a flange. When the horizontal push cylinder 212 is ventilated, the telescopic rod extends and retracts, causing the moving frame 211 to move smoothly horizontally along the sliding structure. The vertical push cylinder 221 is also a pneumatic push cylinder, its cylinder body vertically fixed to the moving frame 211, and the telescopic rod connected to the push frame 222. The push frame 222 is an aluminum alloy frame, and the pressing block 23 is fixed to the bottom of the push frame 222. When the vertical push cylinder 221 is ventilated, the telescopic rod extends and retracts, causing the push frame 222 and the pressing block 23 to move vertically up and down, completing the pressing, fixing, or loosening action of the ceiling assembly.

[0029] In practical applications, the base 1 is provided with a limiting block 8, which is used to abut against the moving frame 211 so that the pressing block 23 is aligned with the pressing fixing position on the roof assembly; the limiting block 8 is provided with a buffer 81 for buffering the moving frame 211. The push frame 222 is provided with a pressure plate 9 for pressing the electrical plug, and the pressure plate 9 is installed on the push frame 222 through the pressing cylinder 91.

[0030] In this embodiment, the sliding structure includes a slide rail 213 and a slider 214. The slide rail 213 is fixedly mounted on the base 1, the slider 214 is slidably connected to the slide rail 213, and the movable frame 211 is fixedly connected to the slider 214.

[0031] Specifically, the slide rails 213 are two parallel, elongated metal tracks, fixedly mounted on the upper surface of the base 1 by bolts. Their length is adapted to the movement range of the movable frame 211, and the extension direction of the slide rails 213 is the horizontal movement direction. The sliders 214 are block-shaped structures that match the slide rails 213, and their number corresponds to the number of slide rails 213. The sliders 214 are fitted onto the slide rails 213 and can slide freely along the slide rails 213. The bottom of the movable frame 211 is fixedly connected to the sliders 214 by bolts, so that the movable frame 211 can move horizontally as the sliders 214 move on the slide rails 213, ensuring the smoothness and accuracy of the movement.

[0032] In this embodiment, the extrusion block 23 is a polyurethane block.

[0033] Specifically, the extrusion block 23 is made of polyurethane, a material with good elasticity and wear resistance. When the extrusion block 23 comes into contact with the roof assembly, it can tightly conform to the roof surface through its own elastic deformation, ensuring both a firm fixation and preventing indentations or damage to the roof surface caused by excessively hard materials. At the same time, the polyurethane material has good aging resistance, which can extend the service life of the extrusion block 23.

[0034] In this embodiment, the pressing mechanism 3 includes a capacitive pressing head 31, a pressing cylinder 32, and a column 33. The column 33 is fixedly installed on the base 1. The cylinder body of the pressing cylinder 32 is fixedly connected to the column 33. The capacitive pressing head 31 is connected to the telescopic rod of the pressing cylinder 32 and is used to move toward the lighting switch on the ceiling assembly.

[0035] Specifically, the support column 33 is a cylindrical metal column, vertically fixed on the base 1, and its height is set according to the height of the lighting switch on the ceiling assembly. The cylinder body of the pressing cylinder 32 is fixed to the support column 33 by a clamp structure, and the telescopic rod of the pressing cylinder 32 faces the lighting switch on the ceiling assembly. The capacitive pressing head 31 is connected to the end of the telescopic rod of the pressing cylinder 32 and has a sensitive pressure sensing function. When the lighting switch needs to be pressed, the pressing cylinder 32 drives the telescopic rod to extend, which moves the capacitive pressing head 31 toward the lighting switch and applies appropriate pressure to complete the pressing action; after pressing, the telescopic rod retracts, which drives the pressing head to reset. The capacitive pressing head 31 can accurately sense the pressing pressure and avoid damage to the switch due to excessive pressure.

[0036] In this embodiment, the image acquisition component 4 is an industrial camera.

[0037] Specifically, the image acquisition unit 4 uses an industrial camera, which is mounted on the base 1 via an adjustable bracket. The lens is aimed at the luminous areas of all the lighting components on the ceiling assembly. The industrial camera features high resolution and high frame rate, enabling it to clearly and quickly capture the luminous signals of the lighting components, including details such as changes in brightness, flickering, and the integrity of the luminous area. It then converts this image information into electrical signals and transmits them to the control unit, providing an accurate basis for determining the qualification of the lighting components.

[0038] In this embodiment, the feedback component 5 is a speaker.

[0039] Specifically, the feedback component 5 uses a high-quality speaker and is mounted on the base 1. When the control component determines that the lighting component on the ceiling assembly is qualified, the speaker will emit a clear qualified prompt tone; when it is determined to be unqualified, the speaker will emit an unqualified prompt tone, so that the operator can quickly know the test results.

[0040] In this embodiment, the base 1 is provided with an anti-static fan 6 for removing static electricity and an encoder 7 for collecting the code of the ceiling assembly. Both the anti-static fan 6 and the encoder 7 are electrically connected to the control component.

[0041] Specifically, the anti-static fan 6 is mounted on the base 1, with its air outlet facing the area where the ceiling assembly is placed. After the ceiling assembly is placed on the support block 11, the control unit activates the anti-static fan 6, blowing ionized air into the area to neutralize the static electricity generated on the surface of the ceiling assembly due to friction, preventing damage to the electronic components on the ceiling. During or after the testing process, the anti-static fan 6 can be turned off according to the instructions of the control unit. The code collector 7 uses a laser scanner, mounted on the base 1 near the edge of the ceiling assembly, with its scanning lens aligned with the coded label on the ceiling assembly. Once the ceiling assembly is fixed, the code collector 7 is activated under the control of the control unit to scan and collect the code on the ceiling assembly, transmitting the coded information to the control unit to achieve individual recording and traceability of the testing information for each ceiling assembly.

[0042] In this embodiment, the base 1 is provided with a forklift slot 12 and adjustable height screw feet 13.

[0043] Specifically, two forklift slots 12 are symmetrically arranged along the length of the bottom of the base 1. The forklift slots 12 are rectangular grooves that run through both sides of the base 1, and their size is adapted to the forklift forks. When it is necessary to move the entire electrical inspection fixture, the forklift forks can be inserted into the forklift slots 12 for easy handling and relocation. Adjustable height screw pads 13 are installed at the four corners of the bottom of the base 1. The screw pads 13 consist of a screw and a pad. The screw engages with the screw hole at the bottom of the base 1. By rotating the screw, the height of the pad can be adjusted, so that the base 1 can be placed stably on different ground surfaces, ensuring the stability of the inspection process.

[0044] In this embodiment, the tooling also includes a protective canopy 10 disposed above the base 1. The protective canopy 10 is equipped with a lighting lamp 101, a multi-layer warning lamp 102, a display 103, and a camera 104 that are electrically connected to the control components.

[0045] Specifically, the protective canopy 10 is a metal frame structure, mounted on top of the base 1 via support pillars, covering the entire inspection area and providing dust and protection. A lighting fixture 101 is installed inside the protective canopy 10. When the ambient light is dim, the control unit activates the lighting fixture 101 to provide sufficient illumination for the canopy assembly. Multi-layer warning lights 102 are installed on the top of the protective canopy 10, with different colors representing different operating states. A display 103 is installed on the side of the protective canopy 10 and connected to the control unit, displaying inspection data, images, and other information in real time. A camera 104 is installed inside the protective canopy 10, enabling real-time monitoring and recording of the inspection process for later traceability and analysis.

[0046] This utility model uses the contour groove of the base to position the canopy assembly, which is then pressed and fixed by a fixing mechanism. A pressing mechanism triggers the lighting switch, an industrial camera detects the light emission status, and the control components work in conjunction with the speaker to provide feedback, thereby achieving automated detection.

[0047] The beneficial effects of this application include: I. Improved testing efficiency and automation level: Through the coordinated work of the fixed mechanism 2 (horizontal push cylinder 212 / vertical push cylinder 221 driving the extrusion block 23), the pressing mechanism 3 (capacitive pressing head 31 automatically triggering switch) and the image acquisition component 4 (industrial camera), the manual pressing and visual observation process is completely replaced, significantly shortening the testing time and adapting to the batch production cycle requirements.

[0048] II. Ensuring Consistency and Accuracy in Testing: The contoured groove of the base 1 support block 11 enables precise positioning of the ceiling, and the polyurethane extrusion block 23 provides elastic fixation to prevent surface damage; the industrial camera captures light signals (brightness, color, flicker, etc.) at high resolution, and the PLC control component objectively determines the passability based on the image data, eliminating subjective human error; the slide rail 213 and slider 214 structure ensures smooth horizontal movement, and the capacitive pressing head 31 accurately simulates human hand pressure, improving the reliability of the action.
