Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a testing device for the outer panel of the rear pillar of an automobile. Background Technology
[0002] In automotive structures, many components are made from sheet metal, such as the rear pillar outer panel. During the manufacturing process, the rear pillar outer panel needs to have corresponding mounting holes, cavities, protrusions, and other structures machined on both sides according to process requirements. After machining, workers need to inspect both sides of the rear pillar outer panel to ensure that no structures were missed during machining.
[0003] In industrial production, using cameras to detect unfinished machining defects on workpiece surfaces is a common quality inspection method. The principle behind camera-based detection of unfinished machining is based on differences in optical properties. Unfinished machining defects on a workpiece surface cause its optical properties to differ from those of normally machined areas. When light shines on the workpiece surface, the unfinished area will exhibit differences in reflection and refraction compared to the surrounding normal area. By capturing these changes in light using an industrial camera and analyzing the intensity changes and image features of the image signal, the location and size of the unfinished machining defect can be identified. Therefore, after the rear column outer panel has been machined, an industrial camera can also be used to inspect its surface.
[0004] Workers place the rear column outer panel on the inspection platform, where it is then photographed and inspected using an industrial camera. After one side of the rear column outer panel is inspected, workers need to flip it over and rearrange it so that both sides can be inspected by the camera. However, during batch inspections, the number of rear column outer panels is large, requiring workers to flip and rearrange a large number of panels one by one, resulting in high labor intensity. Utility Model Content
[0005] In view of the above problems, this utility model provides a detection device for the outer panel of the rear pillar of an automobile.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A testing device for the outer panel of a car rear pillar is provided, including a testing platform with a frame on the testing platform. A mounting seat is provided on the testing platform within the frame. Two brackets are spaced apart on the mounting seat. Coaxial turntables are rotatably mounted on the two brackets. Each turntable is equipped with a material support frame, which has an installation space for accommodating the end of the rear pillar outer panel. One of the brackets is equipped with a first driving component for driving the turntable to rotate. A mounting plate is slidably connected to the top wall of the inner frame via a three-dimensional linear module. An industrial camera for photographing and inspecting the surface of the rear pillar outer panel is mounted on the mounting plate.
[0008] Furthermore, the material support frame includes two trays, and a mounting frame is provided on the turntable. The two trays are rotatably mounted on the mounting frame, and the mounting space is located between the two trays. The mounting frame is provided with two second drive components for driving the two trays to rotate and jointly clamp the outer plate of the rear column. By flipping the tray located above the outer plate of the rear column, the upper surface of the outer plate of the rear column can be fully exposed for industrial camera to take pictures and inspect.
[0009] Furthermore, the tray is provided with multiple vacuum suction cups at intervals for adsorbing and fixing the outer plate of the column, and each vacuum suction cup is connected to a vacuum machine.
[0010] Furthermore, the tray includes a plate body and multiple support columns corresponding to the suction cups. The plate body is rotatably connected to the corresponding mounting bracket, and the multiple support columns are threadedly connected to the plate body to adjust their length extending into the installation space. Multiple vacuum suction cups are set on the corresponding support columns.
[0011] Furthermore, flexible pads are provided on the plate.
[0012] Furthermore, the two brackets are horizontally and linearly slidably mounted on the mounting base, which is equipped with a third driving component for driving the two brackets to move linearly in opposite directions.
[0013] The beneficial effects of this utility model are as follows: the workers install the two ends of the rear column outer plate in the installation space of the two material support racks respectively. The industrial camera can take pictures of the upper surface of the rear column outer plate. After one side of the rear column outer plate has been photographed and inspected, the first driving component can drive the turntable to rotate and flip the rear column outer plate to ensure that both sides of the rear column outer plate can be inspected. During the inspection process, the three-dimensional linear module can drive the mounting plate to move to ensure that the industrial camera can clearly capture the surface of the rear column outer plate, which has the effect of reducing the labor intensity of the workers.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0020] This application discloses a detection device for the outer panel of a car rear pillar, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a testing platform 1, a frame 2 welded to the testing platform 1, and a mounting base 3 bolted to the testing platform 1 within the frame 2. Two supports 4 are spaced apart on the mounting base 3. Coaxial turntables 5 are rotatably mounted on each of the two supports 4. Each turntable 5 is equipped with a material support frame 6, which has mounting space for accommodating the end of the rear column outer panel. One of the supports 4 has a first driving component 52 for rotating the turntable 5. A mounting plate 8 is slidably connected to the inner top wall of the frame 2 via a three-dimensional linear module 7. An industrial camera 9 is mounted on the mounting plate 8 for photographing and inspecting the surface of the rear column outer panel.
[0021] In this embodiment, a display 91 is provided on the outer wall of the frame 2 for displaying images of the rear column outer panel surface captured by the industrial camera 9. The industrial camera 9 is functionally connected to a computer processing system, and the display 91 is also functionally connected to the computer processing system. The images captured by the industrial camera 9 can be processed by the computer processing system and displayed on the display 91, and the processed images will mark the unprocessed parts on the surface of the rear column outer panel.
[0022] Workers install the two ends of the rear column outer panel into the mounting spaces of the two material support racks 6. An industrial camera 9 takes pictures of the upper surface of the rear column outer panel. After one side of the rear column outer panel has been photographed and inspected, the first drive component 52 drives the turntable 5 to rotate, flipping the rear column outer panel to ensure both sides are inspected. During the inspection process, the three-dimensional linear module 7 moves the mounting plate 8 to ensure the industrial camera 9 can clearly capture the surface of the rear column outer panel. This inspection process eliminates the need for manual flipping of the rear column outer panel, reducing worker workload.
[0023] The first driving component 52 includes a first driving motor. A driving wheel is rotatably mounted on one of the brackets 4, and a coaxial driven wheel is fixed on the corresponding turntable 5. The driving wheel and the driven wheel are connected by a transmission belt. The first driving motor is mounted on the corresponding bracket 4, and the output shaft of the first driving motor is connected to the driving wheel. Starting the first driving motor will drive the driving wheel to rotate, thereby enabling the driven wheel and the turntable 5 to rotate, so that the outer panel of the rear column can be flipped.
[0024] Reference Figure 4 The material support frame 6 includes two support plates 61. A mounting frame 51 is welded onto the turntable 5. The two support plates 61 are rotatably mounted on the mounting frame 51, and the mounting space is located between the two support plates 61. The mounting frame 51 is provided with two second drive members 10, which are used to drive the two support plates 61 to rotate and jointly clamp the outer plate of the rear column. By flipping the support plate 61 located above the outer plate of the rear column, the upper surface of the outer plate of the rear column can be fully exposed for photographing and inspection by the industrial camera 9.
[0025] In this embodiment, two second drive members 10 on the mounting bracket 51 drive two trays 61 to rotate and clamp the end of the rear column outer panel. Then, the turntable 5 rotates, flipping the rear column outer panel. When the rear column outer panel rotates to a horizontal position, the corresponding second drive member 10 drives the tray 61 located above the rear column outer panel to flip, allowing the entire upper surface of the rear column outer panel to be exposed for inspection by the industrial camera 9. After one side of the rear column outer panel has been inspected, the other side can be inspected in the same way.
[0026] The second drive unit 10 includes two electric push rods, which are rotatably connected to both sides of the mounting bracket 51, and the movable ends of the two electric push rods are rotatably connected to the corresponding support plate 61.
[0027] Furthermore, the tray 61 is provided with a plurality of vacuum suction cups 20 for adsorbing and fixing the outer plate of the column, and the plurality of vacuum suction cups 20 are respectively connected to a vacuum machine (not shown in the figure).
[0028] In this embodiment, each vacuum suction cup 20 can be connected to a vacuum machine via a flexible air tube. After the rear column outer plate is placed on the tray 61, the vacuum machine draws a vacuum, which allows the vacuum suction cups 20 to adhere and fix the rear column outer plate, thereby improving the installation stability of the rear column outer plate on the tray 61.
[0029] Furthermore, the tray 61 includes a plate body 611 and a plurality of support columns 612 corresponding to the suction cups. The plate body 611 is rotatably connected to the corresponding mounting bracket 51, and the plurality of support columns 612 are threadedly connected to the plate body 611 to adjust their length extending into the installation space. The plurality of vacuum suction cups 20 are respectively set on the corresponding support columns 612.
[0030] Because the surface of the rear column outer panel has mounting holes, cavities, protrusions, and other structures, it is uneven. The rotating support column 612 can adjust the length of its extended mounting space to ensure that the vacuum suction cup 20 can fit against the surface of the rear column outer panel.
[0031] To prevent the plate 611 from causing wear on the surface of the rear column outer plate, a flexible pad 30 is attached to the plate 611. The flexible pad 30 is made of rubber.
[0032] Furthermore, the two supports 4 are horizontally and linearly slidably mounted on the mounting base 3, and the mounting base 3 is provided with a third driving member 40 for driving the two supports 4 to move linearly in opposite directions.
[0033] In this embodiment of the application, the two supports 4 are driven to move in opposite directions by the third driving member 40, and the distance between the two material support frames 6 can be adjusted to ensure that the outer plate of the rear column can be installed between the two material support frames 6.
[0034] The third driving component 40 includes a second driving motor and a bidirectional screw. The bidirectional screw is rotatably connected to the mounting base 3, and two brackets 4 are threadedly connected to the two threaded sections of the bidirectional screw, respectively. The second driving motor is mounted on the mounting base 3, and its output shaft is drivenly connected to the bidirectional screw. A guide rod parallel to the bidirectional screw is provided on the mounting base 3, and the two brackets 4 are movably mounted on the guide rod.
[0035] The implementation principle of the inspection device for the outer panel of a car rear pillar according to this application is as follows: The operator installs both ends of the outer panel of the rear pillar in the mounting spaces of two material carriers 6. An industrial camera 9 takes pictures of the upper surface of the outer panel. After one side of the outer panel has been inspected, the first driving component 52 drives the turntable 5 to rotate, flipping the outer panel to ensure that both sides of the outer panel are inspected. During the inspection process, the three-dimensional linear module 7 drives the mounting plate 8 to move, ensuring that the industrial camera 9 can clearly capture the surface of the outer panel. During the inspection process, the operator does not need to manually flip the outer panel, thus reducing the labor intensity of the operator.
