[0052] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0053] Due to the wide variety of panoramic sunroofs, and in order to ensure the sealing during inspection and to increase the inspection range of the sealing device, it is not only necessary to replace the corresponding inspection terminals for different models of panoramic sunroofs, but also when inspecting other accessories with high requirements for air tightness, it is necessary to additionally customize special inspection terminals, which causes unnecessary waste in inspection efficiency and equipment costs.

[0054] Based on this, please refer to Figures 1 to 3 A sealing detection device is proposed, comprising an upper profiling mold 1 and a lower profiling mold 2 arranged opposite to each other; the upper profiling mold 1 is provided with an air hole 11; the upper profiling mold 1 and the lower profiling mold 2 can be close to or away from each other; the pressing surfaces of the upper profiling mold 1 and the lower profiling mold 2 are both provided with sealing components, and the two sealing components are used to respectively fit with the two sides of the part to be detected in the thickness direction.

[0055] It can be understood that, in the sealing detection device of the present invention, when the upper profiling mold 1 and the lower profiling mold 2 are in contact with each other on both sides of the workpiece detection point in the thickness direction, the sealing component can be deformed due to the extrusion force, thereby effectively eliminating the gap between the mold and the workpiece surface, and then a certain air source pressure is transmitted to the interior of the upper profiling mold 1 through the air hole 11. If the high-pressure airflow does not leak into the interior of the lower profiling mold 2, the detection is qualified, and then the pressure is released again through the air hole 11 to complete the detection work.

[0056] In some embodiments, the pressing surface of the upper profiling mold 1 matches the pressing surface of the lower profiling mold 2. Specifically, the pressing surface of the upper profiling mold 1 and the pressing surface of the lower profiling mold 2 form a concave-convex mold structure that matches each other. Ensure that the pressing surface of the upper profiling mold 1 matches the pressing surface of the lower profiling mold 2, so that when the two molds are closed, the two sides of the workpiece to be detected can be evenly stressed, and the workpiece can be prevented from being deformed due to pressure; and the surface of the workpiece to be detected usually has an arc, so the pressing surface of the upper profiling mold 1 and the pressing surface of the lower profiling mold 2 form a large concave-convex mold structure that matches each other, so that the two can better fit the surface contour of the workpiece to be detected, thereby effectively reducing the gap between the mold and the workpiece to be detected, and then ensuring the accuracy of subsequent detection results. Specifically, the upper profiling mold 1 and the lower profiling mold 2 are both made of silicone material. When pressed, the upper profiling mold 1 and the lower profiling mold 2 can produce a certain deformation according to the contour of the workpiece, fit the workpiece more closely, and have a better sealing effect.

[0057] In some embodiments, the upper profiling mold 1 is provided with a first cavity 12; the lower profiling mold 2 is provided with a second cavity; the opening of the first cavity 12 and the opening of the second cavity are arranged oppositely; the air hole 11 is located in the first cavity; the above-mentioned sealing detection device also includes an air pressure detection device and a numerical display; the air pressure detection device is provided with a detection end and a connection end; the detection end of the air pressure detection device is located inside the first cavity 12; the connection end of the air pressure detection device is located outside the upper profiling mold 1; the numerical display is located outside the upper profiling mold 1 and the lower profiling mold 2; the numerical display is electrically connected to the connection end of the air pressure detection device. This design provides structural support for the sealing detection device to accurately detect the changes in the air pressure inside the cavity and whether there is air leakage. The air pressure detection device displays the detected parameters on the numerical display, which can facilitate the staff to intuitively judge the qualification of the workpiece, and when the air pressure applied by the sealing detection device is lower than the preset value, an alarm signal can be sent to prompt the staff to check whether the equipment is faulty.

[0058] In some embodiments, the sealing assembly includes an annular protrusion 9; the pressing surface of the upper profiling mold 1 and the pressing surface of the lower profiling mold 2 are both provided with an annular protrusion 9; the annular protrusion 9 is arranged around the opening of the first cavity 12 or the opening of the second cavity; the number of circles of the annular protrusion 9 is at least two; and a gap is left between the annular protrusions 9 located on the same pressing surface and adjacently arranged. Specifically, the annular protrusion 9 is an integral structure with the upper profiling mold 1 and the lower profiling mold 2, and the annular protrusion 9 is made of silicone material. After being squeezed, the annular protrusion 9 can produce a certain deformation, so that the annular protrusion 9 can better fit with the surface of the workpiece, thereby effectively ensuring the sealing between the upper profiling mold 1 and the lower profiling mold 2 and the workpiece after the mold is closed; at the same time, the number of annular protrusions 9 is further limited, so that when a certain annular protrusion 9 is damaged and not replaced in time, another annular protrusion 9 can further ensure the overall sealing effect, thereby improving the working stability of the sealing detection device.

[0059] In some embodiments, the sealing detection device further includes a frame 3, a first driving mechanism 4 and a second driving mechanism 5; the fixed end of the first driving mechanism 4 and the fixed end of the second driving mechanism 5 are respectively connected to the frame 3 through a positioning plate 6; the movable end of the first driving mechanism 4 is connected to the top of the upper profiling mold 1; and the movable end of the second driving mechanism 5 is connected to the bottom of the lower profiling mold 2. This design provides structural support for the upper profiling mold 1 and the lower profiling mold 2 to be able to approach and move away from each other.

[0060] In some embodiments, a transition connecting plate 7 is provided at the bottom of the upper profiling mold 1 and the lower profiling mold 2; the movable end of the first driving mechanism 4 and the movable end of the second driving mechanism 5 are both connected to the transition connecting plate 7. Specifically, the material of the transition connecting plate 7 is a galvanized steel plate. The transition connecting plate 7 can increase the effective contact area between the driving mechanism and the profiling mold, thereby preventing the driving mechanism from damaging the mold due to excessive pressure during the process of pressing the two molds. The use of galvanized steel plate to make the transition connecting plate 7 can not only improve the strength of the transition connecting plate 7 and avoid deformation during the pressure process, but also improve the wear resistance of the transition connecting plate 7, preventing the transition connecting plate 7 from being worn during the movement, thereby affecting the service life of the transition connecting plate 7.

[0061] In some embodiments, the sealing detection device further includes a guide rod 8; the guide rod 8 is at least partially disposed between the positioning plates 6, and is used to guide the moving direction of the first drive mechanism 4 and the second drive mechanism 5. Without limitation, a portion of the guide rod 8 may be located between the two positioning plates 6, and the other portion may extend outside the positioning plates 6. The moving direction of the first drive mechanism 4 and the moving direction of the second drive mechanism 5 are both parallel to the axis of the guide rod 8; the transition connecting plate 7 is slidably connected to the guide rod 8. The guide rod 8 can prevent the upper profiling mold 1 and the lower profiling mold 2 from offsetting during the mold closing process, thereby affecting the authenticity of the final airtightness test result.

[0062] In some embodiments, a gas guide joint is provided on the transition connecting plate 7 connected to the upper profiling mold 1; the gas guide joint passes through the transition connecting plate 7 and communicates with the air hole 11. This design provides structural support for the upper profiling mold 1 to be effectively connected to an external air source device.

[0063] In some embodiments, the sealing detection device further includes a pneumatic triplet; the air inlet end of the pneumatic triplet is connected to the peripheral air source device; the air outlet end of the pneumatic triplet is connected to the air guide joint. The peripheral air source device can provide sufficient air source for the pressurization work of the sealing detection device, and the pneumatic triplet can not only filter the air, but also provide structural support for the sealing detection device to provide a stable 5-8kPa air pressure value, thereby ensuring the working stability of the sealing detection device to improve the overall detection accuracy.
