Description

Technical Field

[0001] This invention relates to the field of inspection tool technology, and in particular to an inspection tool for a rear sunroof assembly. Background Technology

[0002] A sunroof installed on the roof of a car can effectively increase the air circulation rate inside the vehicle, increase the entry of fresh air, and also broaden the field of vision, making it easier to shoot with mobile camera equipment.

[0003] The sunroof assembly includes a front sunroof assembly and a rear sunroof assembly. The structure of the rear sunroof assembly can be found in [reference needed]. Figure 11 As shown, it includes a rear frame, several mounting holes on the rear frame through which bolts can pass, and a drain pipe on the rear frame for draining rainwater, and a receiving groove on the rear frame for partially accommodating a retractable sunshade.

[0004] After the rear sunroof assembly is produced, it needs to be inspected using a fixture. During the inspection process, the rear sunroof assembly is first limited using a clamp and positioning structure. The fixture can refer to the sunroof assembly inspection device disclosed in Chinese Patent No. CN103940328B. Generally, the sunroof assembly is clamped and limited by a manual quick clamp. Next, the operator manually checks the setting position of the mounting holes, the concentricity of the mounting holes, and the concentricity of the exhaust pipe. Finally, the operator needs to check the curvature of the end face of the rear sunroof assembly when the sunshade is rolled up.

[0005] The upper surface of the rear sunroof assembly has a curve near the side where the sunshade rolls up. This curve matches the curve of the roof, forming a convex arc in the middle. In actual production, this end face of the rear sunroof assembly may have unevenness or excessive convexity. This problem can cause the sunshade to roll up poorly or even deform. The current testing method involves pressing down on the rear sunroof assembly with a pressure rod. A reference rod with the same curvature as the edge of the rear sunroof assembly is protruding from one side of the pressure rod. The reference rod is positioned above the end face of the rear sunroof assembly to be tested, with a clearance fit. A go / no-go gauge is used to judge the result by passing through the gap between the reference rod and the end face to be tested. If it passes, it is qualified; if it fails, it is unqualified.

[0006] The disadvantages of this inspection method are as follows: the gap between the reference rod and the end face to be inspected is a narrow and long arc-shaped gap. This arc-shaped gap is located in the middle area from the height distribution of the gauge and also in the off-center area from the horizontal distribution of the gauge. This results in the inspection area being a visual blind spot, requiring the operator to bend over and carefully slide the go / no-go gauge across the arc-shaped gap, which leads to low inspection efficiency and inconvenience. Furthermore, during the sliding process of the go / no-go gauge, due to the poor distribution of the arc-shaped gap, the operator needs to operate with their arm suspended in the air, which leads to uneven force application. If the force applied in a local area is too large, it can easily scratch the surface of the part. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies for detecting the curvature of the sunshade retractable end face of the rear sunroof assembly, such as low detection efficiency, inconvenience, and easy scratching of parts. It provides a rear sunroof assembly inspection tool that can quickly detect the curvature of the sunshade retractable end face.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A rear sunroof assembly inspection fixture includes a base, a positioning and clamping module located on the base, and an arc detection module for detecting the curvature of the sunshade's retractable end. The arc detection module includes a pressure rod pressing against the edge of the sunshade's retractable end and an indicator rod protruding from one side of the pressure rod, the lower end of which has an arc consistent with the arc of the sunshade's retractable end. The indicator rod is transparent and has a detection gap between it and the sunshade's retractable end. An indicator module is movable within the indicator rod along the detection direction. The indicator module includes a sliding body embedded and sliding along the detection direction, a detection slider elastically telescopically disposed at the lower end of the sliding body, and an indicator light disposed on the outer wall of the sliding body. The upper end of the detection slider extends to the outside of the sliding body, and a control button for controlling the indicator light's on / off state is elastically telescopically disposed at its end. An on / off module is disposed between the control button and the detection slider. The sliding of the sliding body is controlled by a drive module. When the detection slider passes through the detection gap, the indicator light illuminates. If the detection gap is too small, the local curvature of the sunshade's retractable end is too large, and the test fails. Conversely, if the indicator light does not illuminate, the test passes.

[0010] By adopting the above solution, an arc detection module is added. This module drives the sliding body to move via a drive module, enabling the detection slider to move within the detection distance. If the error range of the detection distance is within the allowable value, the detection slider can smoothly pass through the detection distance. If the detection distance is less than the allowable value, the detection slider will be squeezed upwards, and the control button will move upwards synchronously. Once the control button contacts the upper surface of the indicator rod, it will move downwards relative to the detection slider until it contacts the on / off module. The on / off module is connected and energized, causing the indicator light to illuminate. Since the indicator rod is made of transparent material, the operator can see the light and directly identify whether the product is qualified through the light. In addition, since the detection slider can extend and retract, it will not cause any hard damage to the product during production. The entire detection process is automated, convenient to operate, and saves a lot of time and effort, effectively improving detection efficiency.

[0011] Preferably, the on / off module includes a first slot symmetrically arranged above the side wall of the detection slider outside the sliding body and a metal contact piece interference-inserted into each first slot. The metal contact piece and the indicator light are connected in series by a wire. The lower end of the control button is provided with a metal post that is inserted into the upper end of the detection slider. When the control button descends to the metal post and simultaneously contacts the two metal contact pieces, the indicator light is energized.

[0012] Using the above scheme, the two metal contacts are set independently. Only when the metal pin on the control button descends to contact the two contacts can the disconnected circuit be connected. Normally, the control button is in the raised state, the metal pin is not in contact with the metal contacts, and the circuit is in the disconnected state.

[0013] Preferably, the detection slider includes a detection section and an indicator section that are inserted into each other. The lower end of the detection section is inserted into the detection interval, and the upper end of the indicator section extends to the upper end of the sliding body and is provided with the indicator light inserted at the upper end. An adjustment locking mechanism is provided between the detection section and the indicator section to adjust the lifting stroke of the detection section relative to the indicator section.

[0014] By adopting the above scheme, the detection slider is set as a detection section and an indicator section that fit together. The length between the two can be adjusted by adjusting the locking mechanism. This setting can not only overcome the difference in the total length of the detection slider caused by production errors, but also be applied to different indicator rods to be suitable for different models of rear sunroof assemblies to detect the curvature of the winding end, thus increasing applicability.

[0015] Preferably, the adjusting locking mechanism includes a second slot recessed at the upper end of the detection section, a rack protruding at the lower end of the indicator section and inserted into the second slot, and a toothed block that can engage or disengage from the rack. The movement of the toothed block is controlled by a manual drive unit, and a first elastic element is provided in the second slot to drive the toothed block into the state of engagement with the rack.

[0016] Using the above solution, the locking or unlocking between the indicator section and the detection section can be achieved by adjusting the position of the tooth block. The operator only needs to pull the drive unit to adjust the position of the tooth block, which is convenient to operate.

[0017] Preferably, the manual drive unit includes a moving rod vertically disposed in the second slot, a toothed block fixed to the toothed side of the moving rod near the rack, and a pull rod extending out of the detection section horizontally protruding below the sliding body on the side of the moving rod away from the rack. The first elastic element is sleeved on the pull rod and its two ends elastically abut against the inner wall of the second slot and the moving rod, respectively.

[0018] Using the above scheme, pulling the lever outward will drive the moving rod to overcome the elastic force of the first elastic element, so that the toothed block can disengage from the rack. At this time, the detection section can be moved down or up. When it is moved to a suitable position, the lever is released, and the moving rod will re-engage with the rack under the reset action of the first elastic element, so as to lock the detection section and the indicator section.

[0019] Preferably, a guide mechanism is provided between the moving rod and the detection section to drive the moving rod to slide horizontally and stably. The guide mechanism includes a guide rod that is horizontally protruding above the pull rod on the side of the moving rod away from the tooth block, and a guide groove provided on the inner wall of the second slot for the guide rod to be inserted. When the tooth block engages or disengages from the rack, the guide rod is always in the insertion state with the guide groove.

[0020] By adopting the above scheme, since the position of the pull rod is not in the middle of the moving rod, the guide rod and guide groove are set to drive the moving rod to move stably, ensuring that the toothed block can accurately mesh or disengage with the rack.

[0021] Preferably, the drive module includes drive wheels that are horizontally rotatable at both ends of the indicator rod and a belt tensioned on the drive wheels. A drive motor that drives the drive wheel to rotate is provided above one of the drive wheels, and the sliding body is fixed on the belt.

[0022] Using the above solution, simply turn on the motor. The motor's rotation drives a drive wheel to rotate, which in turn moves the belt and, consequently, the detection module fixed to the belt.

[0023] Preferably, a roller module is provided on the sliding body to increase its sliding smoothness. The roller module includes wheels that are distributed vertically on both sides of the sliding body, and the vertically distributed wheels are respectively attached to the upper and lower end surfaces of the bottom surface of the indicator rod.

[0024] With the above scheme, in the roller module, the upper and lower wheels are located on the upper and lower end faces of the bottom surface of the indicator rod, which guides the movement of the sliding body and improves the smoothness of the movement of the sliding body.

[0025] Preferably, the pressure rod is fixed to the lower end of the manual quick clamp, and the pressure rod is disengaged from or pressed against the rear sunroof assembly as the manual quick clamp is flipped up or down.

[0026] Using the above solution, operators can easily limit the downward movement of the pressure bar or release it by manually clamping it.

[0027] Preferably, the positioning and clamping module includes a positioning block assembly and manually operated quick clamps that are circumferentially spaced around the rear sunroof assembly. The positioning block assembly includes an arc-shaped fitting block that fits against the retractable end of the sunshade of the rear sunroof assembly and a side fitting block that fits against the end of the sunshade away from the retractable end of the sunroof assembly.

[0028] Using the above solution, the horizontal movement of the rear sunroof assembly can be limited by the positioning block group, and the longitudinal movement of the rear sunroof assembly can be limited by the manual quick clamp.

[0029] This invention, by employing the above technical solution, has significant technical advantages: It replaces the existing manual horizontal sliding inspection of the sunshade retraction end curvature of the rear sunroof assembly with the addition of a curvature detection module. This module utilizes a drive module to automatically detect the curvature of the sunshade retraction end. The detection module, driven by the drive module, moves the sliding body, allowing the detection slider to move within the detection distance. If the detection distance error is within the allowable value, the detection slider can smoothly pass through the detection distance. If the detection distance is less than the allowable value, the detection slider will be compressed and move upwards. The control button moves upwards synchronously, and once it contacts the upper surface of the indicator rod, it moves downwards relative to the detection slider until it contacts the on / off module. The on / off module is then connected and energized, illuminating the indicator light. Since the indicator rod is transparent, the operator can see the light and directly identify whether the product is qualified. Furthermore, because the detection slider is retractable, it will not cause any hard damage to the product during production. The entire inspection process is automated, convenient to operate, and saves considerable time and effort, effectively improving inspection efficiency. Attached Figure Description

Sunshade retracting end. Detailed Implementation

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0043] Example

[0044] A rear sunroof assembly inspection tool, referring to Figures 1-10 As shown, the device includes a base 1, on which are provided a positioning and clamping module for positioning and clamping the rear sunroof assembly, a hole position detection module for positioning and detecting the concentricity of the mounting hole 35, an emission detection module for detecting the concentricity of the emission pipe 36, and an arc detection module for detecting the arc of the sunshade retraction end 38.

[0045] Reference Figure 1 As shown, the positioning and clamping module includes a positioning block assembly fixed on the base 1 and manual quick clamps 4 distributed circumferentially around the rear sunroof assembly. The positioning block assembly includes an arc-shaped bonding block 201 that fits against the sunshade retracting end 38 of the rear sunroof assembly and a side bonding block 202 that fits against the end of the sunshade retracting end 38 away from the rear sunroof assembly.

[0046] Reference Figure 2As shown, the hole position detection module includes a support block 3 fixedly mounted on the base 1 for supporting the rear sunroof assembly, and a reference hole 301 recessed at the upper end of the support block 3, which is directly opposite the mounting hole 35 on the rear sunroof. A pressing reference member 5 is fixed on the corresponding manual quick clamp 4, which presses against the rear sunroof assembly when pressed down. The pressing reference member 5 is provided with a reference groove 501 for inserting a go / no-go gauge into the mounting hole 35. A limiting clamping block is provided on the base 1 to clamp the go / no-go gauge for limiting its position. If the go / no-go gauge can smoothly enter the reference hole 301 through the mounting hole 35, the mounting hole 35 is qualified; otherwise, it is unqualified.

[0047] Reference Figure 3 As shown, the emission detection module includes a mounting block 6 fixedly mounted on the base 1 and a telescopic rod 7 that slides elastically on the mounting block 6. One end of the telescopic rod 7 is provided with a detection head 8, and the end of the telescopic rod 7 away from the detection head 8 is provided with a pressing block 9. A fourth elastic element 10, which drives the detection head 8 to be in a retracted state, is sleeved on the telescopic rod 7 between the mounting block 6 and the pressing block 9. The fourth elastic element 10 is a spring. When the rear sunroof assembly is clamped and positioned on the fixture, the operator can drive the detection head 8 to extend or retract by pulling the pull block 31. If the detection head 8 can smoothly enter the emission pipe 36 on the rear sunroof assembly, then the emission pipe 36 is qualified; otherwise, it is unqualified.

[0048] Reference Figures 5-6 As shown, the curvature detection module includes a pressure rod 11 that presses against the edge of the sunshade retracting end 38 when pressed down. The pressure rod 11 is connected to a manual quick clamp 4 on the edge of the sunshade retracting end 38. To improve the stability of the pressure block when pressed down, the pressure rod 11 is connected to multiple manual quick clamps 4 simultaneously. In this embodiment, three manual quick clamps 4 are used. An indicator rod 12 with a length greater than the area to be detected protrudes from the side of the pressure rod 11 near the receiving groove 37 on the rear sunroof assembly. The curvature of the lower end of the indicator rod 12 is consistent with the curvature of the sunshade retracting end 38 and there is a detection gap. The indicator rod 12 is hollow inside and transparent overall. The indicator rod 12 can be made of transparent glass or plastic. A through groove is provided at the lower end of the indicator rod 12 along the detection direction. An indicator module is moved inside the indicator rod 12 along the detection direction, passing through the through groove and located within the detection gap. Figures 9-10As shown, the indicator module includes a sliding body 16 that slides along a through groove, a detection slider 17 that is elastically telescopically disposed at the lower end of the sliding body 16, and an indicator light 20 disposed on the outer wall of the sliding body 16. To improve the smoothness of the movement of the sliding body 16, a roller module is provided on the sliding body to increase its sliding smoothness. The roller module includes wheels 22 that are distributed vertically on both sides of the sliding body, and the vertically distributed wheels 22 are respectively in contact with the upper and lower end faces of the bottom surface of the indicator rod 12. The upper end of the detection slider 17 extends to the outside of the sliding body 16 and has a recessed groove 1721 at the end. A control button 18 for controlling the opening and closing of the indicator light 20 is elastically telescopically disposed in the groove 1721. A battery 21 is fixed on the outer wall of the sliding body 16. An on / off module is disposed between the control button 18 and the detection slider 17. The battery 21, the indicator light 20, and the on / off module are connected in series by a wire 19.

[0049] The on / off module includes first slots 26 symmetrically arranged above the side wall of the detection slider 17 on the outside of the sliding body 16 and communicating with the groove 1721, and a metal contact 27 interference-fitted into each first slot 26. One metal contact 27 is connected in series with the indicator light 20 via a wire 19, and the other metal contact 27 is connected in series with the battery 21 via a wire 19. The lower end of the control button 18 has a protruding metal post 24 that is inserted into the groove 1721. A third elastic element 23, which is a spring, is sleeved on the metal post 24 between the control button 18 and the detection slider 17. When the metal post 24 descends between the two metal contacts 27, and the metal post 24 contacts the two metal contacts 27 simultaneously, the indicator light 20 is energized. This indicates that the detection gap is too small and the arc of the sunshade retracting end 38 is locally too large, exceeding the allowable range, and the detection is unqualified. If the indicator light 20 is not energized, the detection is qualified.

[0050] The sliding of the sliding body 16 is controlled by a drive module, as shown in the reference module. Figure 4 , Figure 7 as well as Figure 8 As shown, the drive module includes drive wheels 13 horizontally rotatable at both ends of the indicator rod 12 and a belt 14 tensioned on the drive wheels 13. A drive motor 15 is disposed above one of the drive wheels 13 to drive the drive wheels 13 to rotate. The sliding body 16 is fixed to the belt 14. The rotation of the drive motor 15 drives the drive wheels 13 to rotate, which in turn drives the belt 14 to transport materials, ultimately realizing the movement of the sliding body 16. The aforementioned drive wheels 13 can be replaced with gears, and the belt 14 can be replaced with a toothed chain.

[0051] To increase applicability and overcome production errors, the detection slider 17 includes a detection section 171 and an indicator section 172 that are interlocked and distributed, as shown in the reference. Figure 10As shown, the lower end of the detection segment 171 is inserted into the detection interval. The lower end of the detection segment 171 is set as a semi-cylindrical shape or a detection roller that rolls along the detection direction. In this embodiment, the former is adopted. The upper end of the indicator segment 172 extends to the upper end of the sliding body 16 and an indicator light 20 is inserted into the upper end. An adjustment locking mechanism is provided between the detection segment 171 and the indicator segment 172 to adjust the lifting stroke of the indicator segment 172 relative to the detection segment 171. A second elastic element 25, which is a spring, is sleeved on the indicator segment 172 between the upper end of the inner wall of the sliding body 16 and the upper end of the detection segment 171 to drive the detection segment 171 to be in a downward extended state.

[0052] The adjusting locking mechanism includes a second slot 1711 recessed at the upper end of the detection section 171, a rack 1722 protruding at the lower end of the indicator section 172 and inserted into the second slot 1711, and a toothed block 29 that can engage or disengage from the rack 1722. The movement of the toothed block 29 is controlled by a manual drive unit. A first elastic member 32 is provided in the second slot 1711 to drive the toothed block 29 to be engaged with the rack 1722. The manual drive unit includes a moving rod 28 vertically disposed in the second slot 1711. The toothed block 29 is fixed to the toothed side of the moving rod 28 near the rack 1722. A pull rod 30 is horizontally protruding below the sliding body 16 on the side of the moving rod 28 away from the rack 1722 and extends out of the detection section 171. The first elastic member 32 is a spring. The first elastic member 32 is sleeved on the pull rod 30 and its two ends elastically abut against the inner wall of the second slot and the moving rod 28, respectively.

[0053] A guide mechanism is provided between the moving rod 28 and the detection section 171 to drive the moving rod 28 to slide horizontally and stably. The guide mechanism includes a guide rod 33 that is horizontally protruding above the pull rod 30 on the side of the moving rod 28 away from the tooth block 29, and a guide groove 34 provided on the inner wall of the second slot for the guide rod 33 to be inserted. When the tooth block 29 is engaged or disengaged from the rack 1722, the guide rod 33 is always in the insertion state with the guide groove 34.

[0054] Operation process:

[0055] Positioning and pressing: Place the rear sunroof assembly to be tested on the support block 3 and make it fit with the side fitting block 202 and the arc-shaped fitting block 201 at the front and back respectively. Then use the manual quick clamp 4 to press it. At this time, the pressure reference piece 5 on the hole detection module and the pressure rod 11 on the arc detection module are pressed down on the upper surface of the rear sunroof assembly.

[0056] Hole position inspection: Pick up the go / no-go gauge and pass it through each mounting hole 35 to be inspected in sequence. If the go / no-go gauge can pass through the mounting hole 35 accurately and smoothly and enter the reference hole 301, then the mounting hole 35 is qualified; otherwise, it is unqualified.

[0057] Emissions test: Press button 9 to drive the test head 8 into the emission pipe 36. If the test head 8 can smoothly pass through the emission pipe 36, then the emission pipe 36 is qualified; otherwise, it is unqualified.

[0058] Radius detection: Start the drive motor 15. In the radius detection module, the sliding body 16 moves with the belt 14. If the indicator light 20 flashes during the movement, the detection is unqualified; if the indicator light 20 does not flash at all, the detection is qualified.
