Description

Technical Field

[0001] This invention relates to the field of wheel hub visual inspection technology, and in particular to a multi-station visual inspection device for the production and processing of high-end automotive aluminum wheel hubs. Background Technology

[0002] High-end automotive aluminum wheels are automotive wheel components made from high-quality aluminum alloy through precision machining processes such as forging and casting. They are widely used in the mid-to-high-end automotive sector. The core reason for visual inspection of high-end automotive aluminum wheels is that the product precision requirements are extremely high. Defects such as scratches and dents on the outer circumference, end face, and bottom surface not only affect the wheel's appearance but may also reduce its structural strength.

[0003] Current inspection methods for wheel hubs require a clamping mechanism to fix the hub in place, which then rotates the hub circumferentially to complete the full circumference inspection. However, existing clamping mechanisms have poor adaptability. For high-end aluminum wheel hubs with different outer diameters and thicknesses, it is often necessary to disassemble and replace the corresponding clamping components. This not only makes the operation process cumbersome and consumes a lot of manual time, but also reduces the overall inspection efficiency and is not easy to adapt to the multi-specification inspection needs in production. On the other hand, during the transportation process, the outer surface of the wheel hub is easily contaminated with dust and other impurities from the environment. These impurities attached to the outer surface of the wheel hub can obstruct the inspection view and interfere with the image clarity of visual inspection, thereby affecting the accuracy of the inspection results.

[0004] Therefore, this application provides a multi-station visual inspection device for the production and processing of high-end automotive aluminum wheels to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-station visual inspection equipment for the production and processing of high-end aluminum wheels for automobiles, so as to solve the problems of poor adaptability of the clamping mechanism in the existing inspection device, the need for frequent clamping changes, and the easy contamination of wheel hubs with impurities during the transportation process, which interferes with the accuracy of the inspection.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A multi-station visual inspection device for the production and processing of high-end aluminum alloy wheels for automobiles includes: an inspection box; conveying mechanisms symmetrically installed on the bottom of the inspection box; a visual inspection mechanism installed on the rear side wall of the inspection box via a multi-axis robotic arm; slide rails symmetrically installed between the left and right side walls of the inspection box; sliders slidably installed at the top of each of the two slide rails via a drive mechanism; the sliders are connected to rotating rods via a motor; fixed frames are installed at the inward ends of each of the two rotating rods; and support bars symmetrically connected to the fixed frames via two electric push rods, with the support bars located away from the fixed frames. A connecting rod is rotatably installed in the groove at one end of the frame. A connecting sleeve is symmetrically rotatably connected to the outside of the connecting rod. An oil tank is installed at the top of the fixed frame. A push plate is sealed and slidably connected inside the oil tank via an electric push rod. The electric push rod is fixedly installed at the top of the fixed frame via the connecting plate. The left and right ports of the oil tank are respectively connected to oil tanks two via hoses. The two oil tanks two are fixed on the outer side of the corresponding support bar away from the fixed frame. A fixing clamping assembly is provided between the connecting sleeve, the connecting rod and the oil tank two. A cleaning assembly is provided between the connecting sleeve and the fixed frame.

[0008] Preferably, a rotating column is fixedly connected at the center of the inside of the fixing frame, and the protrusions at the intersection of the left and right support bars are rotatably sleeved on the outside of the rotating column, with the two support bar protrusions arranged alternately vertically.

[0009] Preferably, the fixing clamping assembly includes two push plates, which are symmetrically and slidably connected inside the oil tank by springs. The push plates are fixedly connected to the outer side of the corresponding connecting sleeve by protruding rods. Each of the two connecting sleeves slides against a moving block at one outward end. The moving block is slidably mounted on the outside of the connecting rod. A push plate is slidably connected to the outside of the moving block. A rubber ring is fixedly connected to one opposite end of the two push plates. Both the push plate and the rubber ring are slidably connected to the outside of the connecting rod.

[0010] Preferably, the two ports of the oil tank are located at the center of the upper and lower parts of the inner cavity of the oil tank, and limit protrusions are provided on both sides of the port of the inner cavity of the oil tank.

[0011] Preferably, a gear one is connected to the opening of the support bar via a motor, and a gear two is engaged with the gear one. The gear two is fixedly installed on the outside of the connecting rod.

[0012] Preferably, the movable block has multiple sliding grooves on its outer side, and a connecting strip is slidably limited inside the sliding groove. The connecting strip is fixedly connected to the inner ring wall of the push plate. Multiple threaded strips are arranged and installed on the outer side of the connecting strip. A threaded sleeve is rotatably connected to the outer side of the movable block, and the threaded sleeve is threadedly engaged with the threaded strip.

[0013] Preferably, the upper and lower sections of the movable block are designed as cylindrical structures, the middle section of the movable block is designed as a conical structure, and the support bar is designed as an arc-shaped structure.

[0014] Preferably, the cleaning component includes a mounting box, which is fixedly mounted on the outside of the connecting sleeve by a fixing strip. The mounting box is slidably connected to the connecting groove at the end of the support strip away from the fixing frame by a sliding strip. An adjusting sleeve is rotatably connected to the outside of the mounting box, and a screw is rotatably connected inside the adjusting sleeve. A mounting plate is mounted on one end of the screw, and a sponge strip is mounted on one end of the mounting plate. The mounting plate is slidably connected in a limiting groove inside the mounting box, and the sponge strip is slidably connected in a through hole on one side wall of the mounting plate.

[0015] Preferably, the mounting box on the left is installed on the outside of the connecting sleeve above the left connecting rod, and the mounting box on the right is installed on the outside of the connecting sleeve below the right connecting rod, with the two mounting boxes on the left and right sides arranged symmetrically.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a fixed clamping assembly, the electric push rod at the top of the fixed frame pushes the push plate one to slide in the oil tank one in a sealed manner. The hydraulic oil is squeezed and delivered to the oil tank two through the hose. The hydraulic oil pushes the push plate two to slide. The push plate two drives the connecting sleeve to slide synchronously along the connecting rod through the convex rod. The connecting sleeve further pushes the moving block, the push plate and the rubber ring to move synchronously. This makes it easy to adjust the height of the rubber ring according to the aluminum wheel hubs of different sizes and thicknesses. This solves the problem of poor clamping adaptability of traditional testing equipment and the need for frequent clamp replacement. By rotating the threaded sleeve to drive the connecting bar to move, the position of the push plate and the rubber ring is adjusted to increase the contact pressure between the upper and lower rubber rings and wheel hubs of different hardness. This makes it easy to adjust the contact pressure between the rubber ring and the wheel hub according to the different characteristics such as the surface hardness of the wheel hub, ensuring that the rubber ring firmly clamps the wheel hub and prevents clamping marks or scratches.

[0018] In the above solution, by setting up a cleaning component, the connecting sleeve slides along the connecting rod, simultaneously driving the mounting box to slide, thereby adjusting the height of the sponge strip. By rotating the adjusting sleeve, the mounting plate moves horizontally within the limiting groove of the mounting box, thus moving the sponge strip closer to or away from the wheel hub. This not only facilitates the cleaning needs of wheel hubs of different sizes but also makes it easy to control the contact pressure between the sponge strip and the wheel hub, avoiding excessive pressure that damages the wheel hub surface or insufficient pressure that leads to incomplete cleaning. During the wheel hub rotation test, the sponge strip wipes and cleans impurities on the outer surface of the aluminum wheel hub, facilitating the timely removal of impurities on the outer surface of the wheel hub throughout the visual inspection process. This effectively eliminates the interference of stains on the clarity of the inspection image, avoids missed defects due to impurities obscuring the image, and improves the accuracy of the inspection results.

Detailed Implementation

[0034] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0035] like Figures 1 to 14As shown, an embodiment of the present invention provides a multi-station visual inspection equipment for the production and processing of high-end aluminum wheel hubs for automobiles, comprising: an inspection box 1, conveying mechanisms 2 symmetrically installed on the bottom of the inspection box 1, a visual inspection mechanism 3 installed on the rear side wall of the inspection box 1 via a multi-axis robotic arm, slide rails 4 symmetrically installed between the left and right side walls of the inspection box 1, sliders 5 slidably installed on the top of each of the two slide rails 4 via a drive mechanism, the sliders 5 being connected to rotating rods 51 via a motor, and fixing frames 6 installed at the inward ends of each of the two rotating rods 51, with supports symmetrically connected on the left and right sides of the fixing frames 6 via two electric push rods. A connecting rod 8 is rotatably installed in the groove at the end of the support bar 7 away from the fixed frame 6. A connecting sleeve 9 is symmetrically connected to the outside of the connecting rod 8. An oil tank 10 is installed at the top of the fixed frame 6. A push plate 11 is sealed and slidably connected inside the oil tank 10 via an electric push rod. The electric push rod is fixedly installed at the top of the fixed frame 6 via the connecting plate. The left and right ports of the oil tank 10 are respectively connected to two oil tanks 12 via hoses. The two oil tanks 12 are fixed to the outside of the corresponding support bar 7 at the end away from the fixed frame 6. A fixing clamping assembly 1 is provided between the connecting sleeve 9, the connecting rod 8 and the oil tanks 12. 3. A cleaning component 14 is provided between the connecting sleeve 9 and the fixing frame 6. The fixing clamping component 13 is used for fixing and clamping the wheel hub, and the cleaning component 14 is used for cleaning the outer circumference of the wheel hub. The high-end aluminum wheel hub to be inspected is automatically conveyed by the conveying mechanism 2, and the aluminum wheel hub is smoothly sent into the designated visual inspection station inside the inspection box 1. Using the slide rail 4 between the left and right side walls of the inspection box 1 as the sliding reference, the slider 5 slides laterally along the slide rail 4 under the action of the driving mechanism. The sliding of the slider 5 drives the rotating rod 51 and the fixing frame 6 to move synchronously, so that the fixing frame 6 moves to the outer position of the aluminum wheel hub to be inspected, and the fixing clamping component is completed. 13. After the wheel hub is aligned and fixed, the vision inspection mechanism 3 is activated to perform multi-station visual photography and defect identification inspection on the appearance of the aluminum wheel hub. After the front and outer periphery of the wheel hub are inspected, the fixing frame 6 moves the wheel hub to the empty area between the two conveying mechanisms 2. The motor drives the rotating rod 51 to rotate, which in turn drives the fixing frame 6, the support bar 7 and the aluminum wheel hub clamped and fixed to rotate as a whole, realizing the switching of the work position of the bottom surface of the aluminum wheel hub. After the wheel hub is rotated into place, the vision inspection mechanism 3 performs multi-station visual acquisition and defect inspection again to complete the all-round appearance quality inspection of the aluminum wheel hub.

[0036] A rotating column is fixedly connected to the center of the fixed frame 6. The protrusions at the intersection of the left and right support bars 7 are rotatably sleeved on the outside of the rotating column. The protrusions of the two support bars 7 are staggered vertically. When the electric push rod on the fixed frame 6 is activated, the expansion of the two support bars 7 can be flexibly adjusted by adjusting the extension distance of the electric push rod to adapt to aluminum wheel hubs of different sizes. At the same time, as the electric push rod pushes the support bars 7 to move, it drives the protrusions to rotate synchronously on the outside of the rotating column. Since the two protrusions are staggered vertically, the rotation of the two protrusions can easily drive the support bars 7 on the left and right sides to perform symmetrical movements synchronously.

[0037] The fixed clamping assembly 13 includes two push plates 131, which are symmetrically and slidably connected to the inside of the oil tank 12 via springs. Each push plate 131 is fixedly connected to the outer side of a corresponding connecting sleeve 9 via a protruding rod. Each connecting sleeve 9 has a sliding contact block 132 at its outward end. The sliding block 132 is slidably mounted on the outside of the connecting rod 8. A push plate 133 is slidably connected to the outside of the sliding block 132. A rubber ring 134 is fixedly connected to the opposite end of each push plate 133. Both the push plate 133 and the rubber ring 134 are slidably connected to the outside of the connecting rod 8. When the push plate 11 is pushed to slide in a sealed manner by the electric push rod at the top of the fixed frame 6, the push plate 11 compresses the hydraulic oil in the oil tank 10. Hydraulic oil is delivered via hose to oil tank 12, which is fixed to the outside of support bar 7. The hydraulic oil entering oil tank 12 pushes push plate 131 to slide against spring force. Push plate 131 drives connecting sleeve 9 to slide along connecting rod 8 via protrusion. During the sliding process, connecting sleeve 9 pushes moving block 132 to slide along connecting rod 8, thereby driving push plate 133 and rubber ring 134 to move synchronously. Finally, rubber ring 134 abuts against the outer circumference of wheel hub. The height of rubber ring 134 can be adjusted according to the different thickness of wheel hub to achieve abutment against wheel hubs of different thicknesses. The rubber ring 134 achieves adaptive flexible support and fixation from the outer circumference of wheel hub, firmly clamping the aluminum wheel hub and avoiding deviation or shaking during the testing process.

[0038] The port of the hydraulic tank 212 is located at the center of the upper and lower part of the inner cavity of the hydraulic tank 212. Limiting protrusions are provided on both sides of the port of the hydraulic tank 212. The limiting protrusions are used to limit the sliding of the push plate 2131. Since the port of the hydraulic tank 212 is located at the center of the upper and lower part of the inner cavity of the hydraulic tank 212, after the hydraulic oil enters the hydraulic tank 212, it will simultaneously act on the two push plates 2131 symmetrically arranged inside the hydraulic tank 212, pushing the two push plates 2131 to slide synchronously against the spring force. The two push plates 2131 respectively drive the upper and lower symmetrical connecting sleeves 9 to slide synchronously along the connecting rod 8 through the corresponding protrusions. During the sliding process of the connecting sleeves 9, the corresponding moving block 132 is pushed synchronously to slide along the connecting rod 8, thereby driving the upper and lower push plates 133 and rubber rings 134 to move synchronously, and finally the upper and lower rubber rings 134 simultaneously abut against the outer circumference of the wheel hub.

[0039] Gear 15 is connected to the opening of the support bar 7 via a motor. Gear 16 meshes with the teeth of gear 15. Gear 16 is fixedly installed on the outside of the connecting rod 8. When the motor is started, it drives gear 15 to rotate at a constant speed. Gear 15 drives gear 16 to rotate synchronously through the meshing of its teeth. When gear 16 rotates, it drives the connecting rod 8 to rotate, thereby driving the rubber ring 134 to rotate. Since the rubber ring 134 is in stable contact with the outer circumference of the wheel hub, the rotation of the rubber ring 134 drives the aluminum wheel hub to rotate synchronously and at a constant speed. During the rotation of the wheel hub, the vision inspection mechanism 3 continuously performs visual acquisition, which facilitates comprehensive inspection of every angle of the outer circumference of the wheel hub, reduces blind spots caused by the stationary wheel hub, and ensures that no part of the outer circumference is missed.

[0040] Multiple grooves are provided on the outer side of the movable block 132. A connecting strip 17 is slidably limited inside the groove. The connecting strip 17 is fixedly connected to the inner ring wall of the push plate 133. Multiple threaded strips are arranged on the outer side of the connecting strip 17. A threaded sleeve 18 is rotatably connected to the outer side of the movable block 132. The threaded sleeve 18 is threadedly engaged with the threaded strips. When the rubber ring 134 is initially pressed against the hub, the threaded sleeve 18 is rotated. Under the action of the threaded engagement between the internal thread of the threaded sleeve 18 and the threaded strips on the outer side of the connecting strip 17, the rotation of the threaded sleeve 18 drives the connecting strip 17 to move along the groove of the movable block 132. When the connecting strip 17 moves, it drives the push plate 133 and the rubber ring 134 to move synchronously, so as to increase the contact pressure between the rubber ring 134 and the hub. This allows for flexible adjustment of the rotation angle of the threaded sleeve 18 according to different characteristics such as the surface hardness of the hub, so as to adjust the contact pressure between the rubber ring 134 and the hub. This ensures that the rubber ring 134 can firmly clamp the hub without damaging the hub surface due to excessive pressure, thus completing the final stable clamping of the hub.

[0041] The upper and lower sections of the movable block 132 are both designed as cylindrical structures, the middle section of the movable block 132 is designed as a conical structure, and the support bar 7 is designed as an arc structure. The cylindrical structure of the movable block 132 is used for the sliding of the movable block 132 along the support bar 7, and at the same time provides a support base for the rotation of the threaded sleeve 18. The arc structure of the support bar 7 is more compatible with the outer contour of the aluminum wheel hub, thereby improving the clamping stability and adaptability.

[0042] Cleaning component 14 includes a mounting box 141, which is fixedly mounted on the outside of the connecting sleeve 9 by a fixing strip. The mounting box 141 is slidably connected to the connecting groove at the end of the support strip 7 away from the fixing frame 6 by a sliding strip. An adjusting sleeve 142 is rotatably connected to the outside of the mounting box 141. A screw 143 is rotatably connected inside the adjusting sleeve 142. A mounting plate 144 is mounted on one end of the screw 143, and a sponge strip 145 is mounted on the other end of the mounting plate 144. The mounting plate 144 is slidably connected in the limiting groove inside the mounting box 141, and the sponge strip 145 is slidably connected in the through hole on one side wall inside the mounting plate 144. When the connecting sleeve 9 slides along the connecting rod 8, it synchronously drives the mounting... The box 141 slides along the connecting groove on the outside of the support bar 7, thereby driving the sponge strip 145 to move synchronously, realizing flexible adjustment of the cleaning range of the sponge strip 145, ensuring that the sponge strip 145 covers the area to be cleaned on the outer periphery of the wheel hub. Rotating the adjusting sleeve 142, with the help of the threaded engagement between the adjusting sleeve 142 and the screw 143, drives the mounting plate 144 to slide along the limiting groove inside the mounting box 141. The movement of the mounting plate 144 synchronously drives the sponge strip 145 to move closer to or away from the wheel hub, which is convenient for adapting to the cleaning needs of wheel hubs of different sizes, and also makes it easy to control the cleaning contact pressure between the sponge strip 145 and the wheel hub, avoiding excessive pressure that damages the surface of the wheel hub or insufficient pressure that leads to incomplete cleaning.

[0043] The left mounting box 141 is installed on the outside of the connecting sleeve 9 above the left connecting rod 8, and the right mounting box 141 is installed on the outside of the connecting sleeve 9 below the right connecting rod 8. The two mounting boxes 141 on the left and right sides are symmetrically arranged vertically. When the left mounting box 141 moves upward with the connecting sleeve 9 above the left connecting rod 8, the right mounting box 141 moves downward with the connecting sleeve 9 below the right connecting rod 8, thereby driving the sponge strips 145 on the left and right sides to move synchronously in opposite directions, so as to achieve full coverage of the cleaning range of the sponge strips 145 to adapt to the cleaning needs of wheel hubs of different sizes.

[0044] The working principle of the technical solution provided by this invention is as follows:

[0045] During the use of this device, the high-end aluminum wheel hub to be inspected is automatically conveyed by the conveying mechanism 2 and smoothly sent into the preset visual inspection station inside the inspection box 1. With the slide rails 4 on the left and right side walls of the inspection box 1 as the guide reference, the slider 5 slides laterally along the slide rails 4, and simultaneously drives the fixing frame 6 to move as a whole, so that the fixing frame 6 moves to the outside of the aluminum wheel hub to be inspected, and completes the position alignment between the fixing clamping component 13 and the aluminum wheel hub. The electric push rod inside the fixing frame 6 is activated. By adjusting the extension and retraction stroke of the electric push rod, the opening and closing range of the two support bars 7 on the left and right are controlled to adapt to aluminum wheel hubs with different outer diameter specifications, and the clamping curvature is initially adapted.

[0046] The push plate 11 is pushed by the electric push rod at the top of the fixed frame 6 to slide and seal inside the oil tank 10. The push plate 11 squeezes the hydraulic oil inside the oil tank 10. The hydraulic oil is delivered to the oil tank 2 12 outside the support bar 7 through the hose. The hydraulic oil enters from the port in the center of the oil tank 2 12 and pushes the push plate 2 131, which is symmetrically arranged inside the oil tank 2 12, to slide against the spring force. The push plate 2 131 drives the two connecting sleeves 9 to slide synchronously along the connecting rod 8 through the convex rod. The movement of the connecting sleeves 9 drives the moving block 132, the push plate 133 and the rubber ring 134 to move synchronously, so that the height of the rubber ring 134 can be adaptively adjusted according to the thickness of the aluminum wheel hub, so that the rubber ring 134 in the upper and lower positions is adjusted accordingly. 34 Simultaneously, it fits against the outer circumference of the wheel hub to achieve flexible adaptive support and positioning. After the rubber ring 134 is initially pressed against the aluminum wheel hub, the threaded sleeve 18 on the outside of the moving block 132 is manually rotated. Through the threaded engagement between the threaded sleeve 18 and the threaded strip on the outside of the connecting strip 17, the connecting strip 17 is driven to slide along the sliding groove of the moving block 132. The movement of the connecting strip 17 drives the push plate 133 and the rubber ring 134 to move, thereby increasing the contact pressure between the rubber ring 134 and the surface of the wheel hub. The contact pressure between the rubber ring 134 and the surface of the wheel hub can be adjusted according to the surface hardness characteristics of the aluminum wheel hub, ensuring that the wheel hub is stable without deviation or shaking, and without damaging the surface of the wheel hub due to excessive pressure, thus completing the stable clamping of the wheel hub.

[0047] During the sliding process of the connecting sleeve 9, the mounting box 141 of the cleaning component 14 is simultaneously driven to slide along the connecting groove on the outside of the support bar 7. When the left mounting box 141 moves upward with the upper connecting sleeve 9 of the left connecting rod 8, the right mounting box 141 moves downward with the lower connecting sleeve 9 of the right connecting rod 8, thereby driving the sponge strips 145 on both sides to move in opposite directions synchronously, so as to achieve all-round coverage of the cleaning range of the sponge strip 145 and adapt to the cleaning needs of different sized wheel hubs. Rotating the adjusting sleeve 142, through the thread transmission between the adjusting sleeve 142 and the screw 143, drives the mounting plate 144 to move horizontally in the limiting groove of the mounting box 141. The movement of the mounting plate 144 synchronously drives the sponge strip 145 to move closer to or away from the wheel hub, which is convenient to adapt to the cleaning needs of different sized wheel hubs and to control the cleaning contact pressure between the sponge strip 145 and the wheel hub, avoiding excessive pressure that damages the surface of the wheel hub or insufficient pressure that leads to incomplete cleaning.

[0048] After the rubber ring 134 and sponge strip 145 are adjusted, the slider 5 slides laterally along the slide rail 4, thereby moving the fixing frame 6 and transferring the wheel hub to the empty area between the two sets of conveying mechanisms 2. The vision inspection mechanism 3 starts working and performs multi-station visual image acquisition on the outer circle, upper end face and other appearance parts of the aluminum wheel hub. The motor drives gear 15 to rotate, thereby driving gear 2 16 to rotate at a constant speed. Gear 2 16 drives the connecting rod 8 and the clamped aluminum wheel hub to rotate slowly circumferentially. During the rotation of the wheel hub, the vision inspection mechanism 3 continuously acquires images from multiple angles to perform defect identification and detection on the entire outer periphery of the wheel hub, reducing blind spots in the detection and realizing the external Every detail is thoroughly inspected. Simultaneously, as the wheel hub rotates at a constant speed with the rubber ring 134, the sponge strip 145 wipes and cleans impurities from the outer surface of the aluminum wheel hub, reducing interference from dirt on visual inspection and ensuring clear imaging. After the front and outer periphery of the aluminum wheel hub are inspected, the rotating rod 51 is driven to rotate by the motor on the outside of the slider 5, thereby causing the fixing frame 6, support strip 7, and aluminum wheel hub to rotate synchronously, completing the switching of the inspection station. This allows the bottom surface of the aluminum wheel hub to face the inspection angle of the visual inspection mechanism 3. At this time, the visual inspection mechanism 3 performs multi-station visual image acquisition and defect identification and judgment on the bottom surface of the aluminum wheel hub, completing the all-round, no-dead-angle appearance quality inspection of the aluminum wheel hub.
