Description

Technical Field

[0001] This invention relates to the field of optical inspection technology, and in particular to an intelligent optical inspection device for flywheel housings. Background Technology

[0002] The flywheel housing, also commonly known as the flywheel cover, clutch housing, or gearbox housing, is a crucial structural component in the internal combustion engine power system of automobiles, construction machinery, and other vehicles. It is a large casting or stamped part connected to the rear end of the engine block, with its front end fixed to the engine block by bolts and its rear end connected to the gearbox or transmission.

[0003] The quality of the flywheel housing is directly related to the performance and reliability of the powertrain, therefore its production process is subject to extremely strict and continuous testing.

[0004] Current inspection methods for flywheel housings mainly include probe inspection and image inspection. Image inspection involves taking an optical image of the contour and then using the resulting two-dimensional dimensional data for automatic measurement by software. Although the inspection efficiency is very high, it requires a lot of external space when not in use because of its fixed structure. Moreover, it cannot perform a 360° full-angle scan of the inner and outer contours of the flywheel housing layer by layer, resulting in relatively simple and incomplete scan data. Summary of the Invention

[0005] The technical problem that this invention aims to solve is that current image detection modules for flywheel housings have a fixed structure, require a large amount of external space when not in use, and cannot perform 360° full-angle scanning of the inner and outer contours of the flywheel housing layer by layer, resulting in relatively simple and incomplete scanning data.

[0006] The technical solution adopted by the present invention to solve its technical problem is: an intelligent optical inspection device for flywheel housing, including a horizontal main frame, wherein a first electrically controlled conveyor belt and a second electrically controlled conveyor belt are installed at the upper end of the interior of the horizontal main frame, and an electrically controlled translation and flipping frame is arranged inside the horizontal main frame below the second electrically controlled conveyor belt, wherein an electrically controlled rotating optical inspection module is movably assembled inside the electrically controlled translation and flipping frame.

[0007] The inner walls on both sides of the horizontal main frame are equipped with a first embedded transverse guide rail and an embedded longitudinal guide rail at the assembly end of the first electrically controlled conveyor belt, and the inner walls on both sides of the horizontal main frame are equipped with a second embedded transverse guide rail at the assembly end of the electrically controlled translation and flipping frame.

[0008] The first embedded transverse guide rail, the embedded longitudinal guide rail, and the second embedded transverse guide rail are all equipped with built-in electrically controlled lead screws.

[0009] The first electrically controlled conveyor belt includes a main drive wheel, a main and driven wheel that is threaded onto the built-in electrically controlled lead screw via a transverse internal thread translation block, a tensioning wheel that is threaded onto the built-in electrically controlled lead screw via a longitudinal internal thread translation block, and a first conveyor belt.

[0010] The electrically controlled rotary optical inspection module includes a main inspection frame that is threaded onto a built-in electrically controlled lead screw via internally threaded translation blocks on both sides, a flip support rod installed inside the horizontal main frame, and a rotary optical scanning unit installed inside the main inspection frame.

[0011] The inner arc-shaped surface of the main detection frame is provided with an annular guide rail for mounting a rotating optical scanning unit.

[0012] The rotating optical scanning unit includes an internal detection ring inserted inside the annular guide rail, an optical scanning module mounted on the internal detection ring, and a drive wheel module.

[0013] Annular LED lighting strips are installed on both sides of the optical scanning module on the inner arc-shaped surface of the internal detection ring.

[0014] Lateral guide frames are installed on the inner walls of both sides of the horizontal main frame above the first electrically controlled conveyor belt.

[0015] The optical scanning module and the drive wheel module are offset and set on the arc-shaped surfaces on both sides of the internal detection ring.

[0016] The beneficial effects of this invention are: (1) The intelligent optical inspection device for flywheel housing of the present invention adopts an adjustable flip structure design, which can set the electrically controlled translation and flip frame below the second electrically controlled conveyor belt when idle, without occupying external space, thus improving safety and durability; (2) The electronically controlled translation and flipping frame can be translated and flipped, and the detection angle can be adjusted as needed, which greatly improves its optical scanning range; (3) An electrically controlled rotating optical detection module is movably assembled inside the electrically controlled translation and flipping frame. It can rotate and adjust along the electrically controlled translation and flipping frame, and perform 360° layer-by-layer scanning as the flywheel housing moves, greatly improving the optical scanning data. (4) The first electrically controlled conveyor belt can be moved and adjusted inside the horizontal main frame, thereby changing the gap with the second electrically controlled conveyor belt and being linked with the electrically controlled translation and flipping frame, greatly improving the level of intelligence.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Figure 1 , Figure 2 , Figure 3 and Figure 4 The intelligent optical inspection device for flywheel housing shown includes a horizontal main frame 1. A first electrically controlled conveyor belt 2 and a second electrically controlled conveyor belt 3 are installed at the upper end of the horizontal main frame 1. An electrically controlled translation and flipping frame 4 is arranged inside the horizontal main frame 1 below the second electrically controlled conveyor belt 3. An electrically controlled rotating optical inspection module 5 is movably assembled inside the electrically controlled translation and flipping frame 4.

[0026] To facilitate guidance, the inner walls on both sides of the horizontal main frame 1 are equipped with a first embedded transverse guide rail 101 and an embedded longitudinal guide rail 102 at the assembly end of the first electrically controlled conveyor belt 2, and the inner walls on both sides of the horizontal main frame 1 are equipped with a second embedded transverse guide rail 103 at the assembly end of the electrically controlled translation and flipping frame 4.

[0027] To facilitate translation and lifting, the first embedded horizontal guide rail 101, the embedded vertical guide rail 102, and the second embedded horizontal guide rail 103 are all equipped with built-in electric control lead screws 104.

[0028] To facilitate the translational material guiding, the first electrically controlled conveyor belt 2 includes a main drive wheel 21, a main and driven wheel 22 threaded onto the built-in electrically controlled lead screw via a transverse internal thread translation block, a tension wheel 23 threaded onto the built-in electrically controlled lead screw via a longitudinal internal thread translation block, and a first conveyor belt 24.

[0029] The built-in electric control screw 104 inside the first embedded transverse guide rail 101 rotates to drive the main and driven wheels 22 to move horizontally. The built-in electric control screw 104 inside the embedded longitudinal guide rail 102 rotates to drive the tension wheel 23 to rise and fall, controlling the first conveyor belt 24 to press downward and maintain tension.

[0030] To facilitate translation and flipping, the electrically controlled rotary optical inspection module 5 includes a main inspection frame 51 threaded onto a built-in electrically controlled lead screw 104 via translation blocks with internal threads on both sides, a flipping support rod 52 installed inside the horizontal main frame 1, and a rotary optical scanning unit 53 installed inside the main inspection frame 51.

[0031] To facilitate internal installation and guidance, an annular guide rail 54 for mounting the rotating optical scanning unit 53 is provided on the inner arc-shaped surface of the main detection frame 51.

[0032] To facilitate assembly and driving, the rotary optical scanning unit 53 includes an internal detection ring 531 inserted inside the annular guide rail 54, an optical scanning module 532 mounted on the internal detection ring 531, and a drive wheel module 533.

[0033] The drive wheel module 533 starts to rotate, which drives the internal detection ring 531 to rotate along the annular guide rail 54. At the same time, the flywheel housing moves along the first electronically controlled conveyor belt 2, and the optical scanning module 532 rotates 360° longitudinally, thereby performing optical scanning of the inner and outer contours of the flywheel housing in all directions.

[0034] To improve the accuracy of optical scanning, ring-shaped LED lighting strips 534 are installed on both sides of the optical scanning module 532 on the inner arc surface of the internal detection ring 531.

[0035] Shadows are avoided by illuminating both sides with ring-shaped LED light strips 534 on both sides.

[0036] In order to guide the flywheel housing conveyed at the upper end, lateral guide frames 6 are installed on the inner walls of both sides of the horizontal main frame 1 above the first electrically controlled conveyor belt 2.

[0037] An optical positioning module is installed inside the side guide frame 6. It can perform optical positioning after the flywheel housing is introduced. Then, the optical positioning module is used to automatically activate the first electrically controlled conveyor belt 2 and the electrically controlled translation and flipping frame 4, so that they can be automatically unfolded and stored.

[0038] To facilitate staggered installation and improve the utilization of internal space, the optical scanning module 532 and the drive wheel module 533 are staggered and set on the arc-shaped surfaces on both sides of the internal detection ring 531.

[0039] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
