DETAILED DESCRIPTION

[0032] The embodiment of the present application solves the problem by providing a detection device for detecting defects in the outer shell of an automobile bumper.

[0033] Example 1:

[0034] A detection device for detecting defects in the outer shell of an automobile bumper, such as Figure 1-Figure 5 As shown, it includes four detection cameras 4, a plurality of reflectors 6 located between the four detection cameras 4, a base 3 arranged at the bottom of the detection cameras 4 and the reflectors 6, and a plurality of erection structures 9 located at the top of both ends of the base 3. The centers of the two long sides of the base 3 are assembled with erection arms 2, one side of the top of the two erection arms 2 is assembled with a suspension base plate 1, and the bottom of the two suspension base plates 1 and the top of the two long sides of the base 3 are assembled with electric slide rails (its control method and application principle adopt the existing technology);

[0035] Among them, the four electric slide rails all include a linear slide rail track 8, and the outer side of the linear slide rail track 8 is slidably connected to a linear slide rail slide 5. By assembling and fixing the four inspection cameras 4 with the linear slide rail slides 5 on the four electric slide rails respectively, when the car bumper is buckled on the top of the multiple erection structures 9, the two inspection cameras 4 at the top are aimed at the outer curved surface of the car bumper, and the two inspection cameras 4 at the bottom are aimed at the inner side of the reflector 6. Based on the inspection cameras 4, images of the inner and outer surfaces of the car bumper can be obtained, thereby detecting defects on the car bumper based on the existing industrial inspection camera (its image processing, marking of the target area, and presentation of the image to the computer terminal all adopt existing technologies, which will not be elaborated in detail);

[0036] Secondly, two positioning seat strips 11 are assembled and connected at the center of the top of the base 3, and the bottoms of the multiple reflectors 6 are all integrally formed with positioning seat rods 10. By making the two positioning seat strips 11 parallel to the direction in which the detection camera 4 moves along the electric slide rail, the positioning seat rods 10 are movably connected to the inside of the positioning seat strips 11. When the multiple reflectors 6 on the top of the two positioning seat strips 11 are leaned against each other (that is, the multiple reflectors 6 are arranged back to back in pairs), they can be arranged in a row;

[0037] At the same time, by processing the multiple reflectors 6 into single lenses and forming a prism shape as a whole (the inner and outer surfaces are parallel), the inner surfaces of the multiple reflectors 6 are made into reflective surfaces. When the two detection cameras 4 located at the bottom collect images of the inner surface of the car bumper, the light can be reflected by the inner sides of the multiple reflectors 6. In conjunction with the detection camera 4 itself being able to rotate a certain angle, the bumper inner surface can be inspected from multiple angles, with relatively comprehensive coverage.

[0038] Furthermore, in order to fill in the light to the inner surface of the car bumper, the two detection cameras 4 at the bottom can obtain a clear image of the inner surface of the car bumper through multiple reflectors 6, such as Figure 1 As shown, a fill light 7 is provided at the center of the top of the base 3. The fill light 7 is provided parallel to the two positioning seat bars 11 and emits light from the surface of the base 3 to the surroundings. When the light emitted by the base 3 passes through the outer side of the reflector 6 and illuminates the inner curved surface of the car bumper through the inner side of the reflector 6, the inner surface of the car bumper can be clearly observed with the help of the mirror surface inside the reflector 6.

[0039] At the same time, the four detection cameras 4 are driven by four electric slide rails respectively, and can respectively detect the inner and outer surfaces of the car bumper.

[0040] The utility model discloses a detection device for detecting defects in the outer shell of an automobile bumper. The device comprises a plurality of reflectors 6 arranged in two rows and back-to-back, and the automobile bumper is buckled at the bottom of a plurality of erection structures 9 from top to bottom. When four detection cameras 4 are respectively driven by four electric slide rails to move on both sides of the top and bottom of the bumper and cooperate with the camera lenses of the detection cameras 4 to rotate in a small range, based on the detection technology of existing industrial detection cameras, the two detection cameras 4 located at the top can detect the outer surface of the bumper, while the two detection cameras 4 located at the bottom can fill in light to the inner surface of the bumper based on the fill light 7 between the two rows of reflectors 6, and the image of the inner surface of the bumper is reflected by the mirror surface inside the reflector 6, so as to facilitate the detection of the inner surface of the bumper.

[0041] Example 2:

[0042] On the basis of Example 1, Figure 1 、 Figure 2 and Figure 6 As shown, this embodiment is a specific structure of the erection structure 9, and multiple erection structures 9 all include a vertical rod 905, one end of the vertical rod 905 is threadedly connected to an adjusting screw sleeve 902, one end of the adjusting screw sleeve 902 is processed with a supporting core rod 906, and the outer wall of the middle part of the adjusting screw sleeve 902 is processed with multiple control heads 904;

[0043] The fastening nut 903 is threadedly connected to one end of the vertical rod 905. When one end of the vertical rod 905 is threadedly connected to the interior of the base 3, the threaded connection between the fastening nut 903 and one end of the vertical rod 905 can be adjusted so that the bottom of the fastening nut 903 is supported on the top surface of the base 3, thereby facilitating the fixing of the vertical rod 905 to the top of the base 3.

[0044] Secondly, by sleeve-fitting the supporting rubber sleeve 901 onto the outside of the supporting core rod 906, one end of the supporting rubber sleeve 901 is processed into a ball head. When the ball head ends of the supporting rubber sleeves 901 on the multiple erection structures 9 are all supported on the inner curved surface of the car bumper (one end of the multiple supporting rubber sleeves 901 is adapted to be connected to the inner surface of the bumper to keep the bumper in a vertical buckled state), the bumper can be restricted from sliding on the top of the multiple erection structures 9, and the bumper can be erected between the four detection cameras 4.

[0045] The present invention is a detection device for detecting defects in the outer shell of an automobile bumper. The device threadably connects a vertical rod 905 to the top of a base 3, and uses a fastening nut 903 to apply pressure to the surface of the base 3 to limit the rotation of the vertical rod 905 inside the base 3. The control head 904 controls the external rotation of the adjusting screw sleeve 902 and the other end of the vertical rod 905, and adjusts the threaded connection between the adjusting screw sleeve 902 and the vertical rod 905. The height of one end of the supporting rubber sleeve 901 is controlled by the supporting core rod 906 at one end of the adjusting screw sleeve 902, so as to accurately adjust the length of multiple erection structures 9 according to the curvature of the inner surface of the automobile bumper to be detected, so as to set the bumper vertically and wait for the subsequent four detection cameras 4 to slide on the outside of the electric slide rail to perform a comprehensive inspection of the bumper.

[0046] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
