Description

Technical Field

[0001] The utility model relates to the field of measuring devices, in particular to an image acquisition mechanism for automatically measuring the thickness of a bladder skin. Background Art

[0002] Air suspension is a technology used in automotive suspension systems. It uses air springs as elastic elements and compressed air to adjust the height and hardness of the vehicle, thereby improving ride comfort and vehicle handling. The air suspension system includes air springs, shock absorbers, guide mechanisms, and a vehicle height control system.

[0003] The bladder (also known as the airbag) is the core component of an air spring. It is a rubber bladder filled with compressed air. Controlling the inflation volume adjusts the vehicle body height and suspension system stiffness. Inspecting the bladder's thickness, height, and other dimensions, as well as dimensional deviations, to ensure they meet production requirements, is a crucial aspect of ensuring bladder quality. Current automated measurement devices typically consist of an image acquisition mechanism and a host computer. The image acquisition mechanism captures images of the workpiece being measured, which the host computer then processes and analyzes to calculate the workpiece's dimensions. However, there is currently no image acquisition device specifically designed to measure bladder thickness.

[0004] Therefore, there is an urgent need for an image acquisition device that can take multi-point photos of the end of the capsule skin to be applied to the automatic measurement of the thickness of the capsule skin. Summary of the Invention

[0022] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0023] like Figures 1-4 As shown, an image acquisition mechanism for automatically measuring the thickness of the capsule skin includes a fixture 8, a first electric slide module 31, an electric rotating table 32, a second electric slide module 33 and a camera 34.

[0024] like Figure 3 and Figure 4 As shown, a jig 8 is used to vertically position the bladder skin a. In one embodiment, the jig 8 comprises an upper plate 80, a connecting rod 81, a lower plate 82, and a workbench 7. The lower plate 82 is fixed to the workbench 7, and the upper plate 80 is fixed above the lower plate 82 via the connecting rod 81. During use, the lower end of the bladder skin a is nested in the lower plate 82 and abuts the workbench 7, while the upper end of the bladder skin a is nested in the upper plate 80.

[0025] like Figure 4 As shown, preferably, the upper plate 80 is provided with two symmetrically arranged recesses 801 so as to facilitate manual or robotic clamping of the capsule skin a from the jig 8 .

[0026] like Figure 3 、 Figure 4 and Figure 5 As shown, of course, the fixture 8 only needs to be able to vertically and fixedly place the capsule skin a and ensure that the upper end of the capsule skin a is exposed and can be photographed, and is not limited to the above structure. Figure 5 As shown, the fixture 8 includes a workbench 7 , and a frustum-shaped column 81 is fixedly provided on the workbench 7 , and the frustum-shaped column 81 replaces the upper plate 80 , the connecting rod 81 and the lower plate 82 .

[0027] like Figure 1 and Figure 2 As shown, the electric rotary table 32 is horizontally extended with a second electric slide module 33, and the slide of the second electric slide module 33 is vertically fixed with a camera 34. The second electric slide module 33 is used to move the camera 34 horizontally to the upper end surface contour of the capsule skin a, and the electric rotary table 32 is used to intermittently rotate the camera 34 along the upper end surface contour of the capsule skin a.

[0028] like Figure 1 and Figure 2 As shown, more specifically, the first electric slide module 31 is vertically extended, the slide of the first electric slide module 31 is fixed with a first mounting seat 311, and the first mounting seat 311 is horizontally and invertedly fixed with the electric rotating platform 32.

[0029] like Figure 1and Figure 2 As shown, the rotating platform of the electric rotating platform 32 is located at the bottom of the first mounting seat 311 , and the rotating platform of the electric rotating platform 32 is fixed with a second mounting seat 321 . The second mounting seat 321 is horizontally extended to be provided with a second electric slide module 33 .

[0030] like Figure 1 and Figure 2 As shown, the slide of the second electric slide module 33 is fixed with a third mounting base 331. The third mounting base 331 is vertically fixed with a camera 34, and a fill light 35 is also fixed for the camera 34. The fill light 35 includes but is not limited to a ring light.

[0031] It should be noted that the first electric slide module 31 , the electric rotary table 32 and the second electric slide module 33 all belong to the existing technology, and their specific structures are not described here in detail.

[0032] During use, the capsule skin a is placed vertically on the jig 8. Then, the second motorized slide module 33 moves the camera 34 horizontally to the contour of the upper end surface of the capsule skin a. The motorized rotary stage 32 then intermittently rotates the camera 34 along the contour of the upper end surface of the capsule skin a. During each intermittent rotation, the camera 34 captures a partial image of the upper end surface of the capsule skin a, repeatedly capturing multiple points of the upper end surface of the capsule skin a. Preferably, the angle of intermittent rotation is greater than the viewing angle of the camera 34.

[0033] like Figures 1-5 As shown, a capsule size measuring device includes a frame 6 and a workbench 7 intermittently rotatably arranged on the frame, and the workbench 7 is provided with five fixtures 8 distributed in a ring. The frame 6 is equipped with an image acquisition mechanism 3 with the structure described above on the side of one of the fixtures 8.

[0034] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
