Description

Technical Field

[0001] This utility model relates to the field of tire inspection technology, specifically to a tire outer wall bulge detection device and support mechanism. Background Technology

[0002] As the only component of a car in contact with the road surface, the quality of tires directly affects driving safety, fuel economy, and ride comfort. During tire production, defects such as air bubbles, broken cords, or uneven joints may occur inside the tire carcass due to factors like materials, processes, or equipment. These defects manifest as localized bulges on the finished tire. Tire bulges are a serious quality hazard, easily leading to tire blowouts at high speeds, posing a significant threat to life and property. Therefore, rigorous bulge testing before tires leave the factory is an indispensable quality control step in the production process.

[0003] Currently, the tire manufacturing industry mainly uses the following methods to detect bulges on the tire wall: First, the traditional manual visual inspection method, where workers identify abnormal protrusions on the tire surface by visual observation and touch. This method relies on the operator's experience, is labor-intensive, and inefficient. Second, automated inspection based on machine vision, which uses industrial cameras to capture images of the tire sidewalls and then uses image processing algorithms to analyze contours or grayscale changes in the images to identify bulges.

[0004] However, while machine vision-based methods improve efficiency, their detection performance is significantly affected by ambient light, tire surface tread, color, and reflectivity. It is difficult to extract bulge features that are the same color as the tire tread or have inconspicuous reflectivity, which can easily lead to misjudgments.

[0005] Therefore, a tire outer wall bulge detection device and support mechanism are designed to solve the technical problem that machine vision is unable to detect bulges that are the same color as the tire tread or have poor reflectivity in the existing technology.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0030] Research has revealed that the tire manufacturing industry currently employs several methods to detect bulges on the tire wall: First, the traditional manual visual inspection method, where workers rely on their eyes and touch to identify abnormal protrusions on the tire surface. This method is labor-intensive and inefficient, depending on the operator's experience. Second, automated inspection based on machine vision, which uses industrial cameras to capture images of the tire sidewall and then uses image processing algorithms to analyze contours or grayscale changes in the images to identify bulges. However, while machine vision-based methods improve efficiency, their detection effectiveness is significantly affected by ambient light, tire tread patterns, color, and reflectivity. It is difficult to extract features from bulges that are the same color as the tire tread or have inconspicuous reflectivity, leading to frequent misjudgments.

[0031] Based on the above research, this disclosure provides a tire outer wall bulge detection device and support mechanism. The device includes a support mechanism, a drive mechanism, and a detection mechanism. The support mechanism secures the tire to be inspected, preventing tire movement during subsequent inspection and ensuring the inspection structure remains intact. The drive mechanism's motor rotates the detection cylinder and detection rod around the tire outer wall. A contact detection disc threaded to the bottom of the detection rod constantly contacts and rotates against the tire wall. When a bulge appears on the tire outer wall, the contact detection disc is forced to slide the detection rod upwards. Compared to machine vision inspection in existing technologies, this device does not need to consider ambient light, tire surface tread, color, or reflectivity. It can detect bulges that are the same color as the tire tread or have inconspicuous reflectivity by observing whether there is relative sliding between the detection rod and the detection cylinder.

[0032] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, when starting to detect bulges on the outer wall of tire 2, tire 2 must first be securely placed on the outside of base 1. Base 1, as the base of the entire device, is usually made of high-strength steel to ensure stability and durability. Operators need to check whether the inner wall of tire 2 is clean and free of debris to prevent interference when the support mechanism 3 is working. Subsequently, the operator manually rotates the rotating wheel 30, which is usually 15-20 cm in diameter, to provide sufficient torque. The rotation of the rotating wheel 30 drives the rotating shaft 300 to move. The rotating shaft 300 passes through the outer wall of the base 1 and is connected by bearings to ensure smooth rotation and reduce friction loss. One end of the rotating shaft 300 located inside the base 1 is fixed with a driving helical gear 301. The driving helical gear 301 meshes with the driven helical gear 310. When the driving helical gear 301 rotates, it drives the driven helical gear 310 to rotate through tooth surface meshing. The driven helical gear 310 is fixed on the bidirectional threaded screw 31, thereby making the bidirectional threaded screw 31 rotate synchronously. The rotation of the bidirectional threaded screw 31 is a crucial step. Its two threads are designed in opposite directions (left-hand and right-hand), allowing the two support members 32 meshing with it to move synchronously and in opposite directions. The support members 32 are usually made of rubber or polyurethane material to softly contact the inner wall of the tire and avoid scratching the tire body. The operator needs to slowly rotate the wheel 30 and observe the movement of the support members 32 until the two support members 32 on both sides firmly contact the inner wall of the tire 2. This process must ensure that the contact force is uniform to avoid excessive tightness causing tire deformation or excessive looseness causing shaking. The fixation of the tire 2 is the basis of the test and can effectively prevent tire displacement during subsequent rotation tests, thereby ensuring the accuracy of the test results. If the tire size is large, the operator can repeatedly adjust the wheel 30 and fine-tune the position of the support members 32 to adapt to different tire sizes.

[0036] In some embodiments, such as Figure 3As shown, when the bidirectional threaded screw 31 rotates, two movable seats 33 are respectively engaged on its two threads. The movable seats 33 are usually slider structures and are connected to the bidirectional threaded screw 31 through a threaded pair to ensure smooth movement. The two movable seats 33 are driven away from each other by the thread. Each movable seat 33 is fixed with a support plate 34. The lower end face of each support plate 34 is connected to at least one pair of support members 32 by bolts. This modular design allows for quick replacement of support members 32 to adapt to tires 2 of different widths. When the support member 32 touches the inner wall of the tire 2, the tire 2 is completely fixed and stationary, creating a stable environment for testing. Subsequently, the drive motor 40 is started. The drive motor 40 is preferably a servo motor or a stepper motor. Its output end is connected to the upper end face of the drive base 41. The lower end face of the drive base 41 is connected to the upper end face of the base 1 through a bearing. The upper end face of the drive motor 40 can be fixed to an external hoisting device (such as a robotic arm). After the drive motor 40 is started, it drives the drive base 41 to rotate. A pair of grooves 410 are symmetrically opened on the outer wall of the drive base 41. The shape of the grooves 410 matches the outer wall contour of the drive rod 42 to ensure a firm engagement. One end of the two drive rods 42 can be fixed by a connecting plate to form a rigid structure to prevent loosening during rotation. This allows the drive rods 42 to rotate synchronously with the drive base 41 and transmit power to the detection mechanism 5. The operator needs to adjust the position of the detection mechanism 5 to fit the size of the tire 2. First, rotate the connecting bolt 54 to separate the upper clamping plate 52 and the lower clamping plate 53. The upper clamping plate 52 and the lower clamping plate 53 are made of high-strength steel. The upper and lower end faces of the two plates are respectively provided with a first semi-circular groove 520 and a second semi-circular groove 530. The diameter of the grooves is slightly larger than the outer diameter of the drive rod 42 to provide adjustment space. According to the current radius of the tire 2, the operator moves the upper clamping plate 52 and the lower clamping plate 53 to slide along the drive rod 42 until the detection rod 51 is located directly above the tire 2. After the position is determined, tighten the connecting bolt 54 again to merge the upper and lower clamping plates. At this time, the first semi-circular groove 520 and the second semi-circular groove 530 fit together and cover the outer wall of the drive rod 42 to form a tight connection. This clamping design avoids slippage and ensures that the detection mechanism 5 will not be displaced during rotation, thus improving the reliability of the detection. If the size of the tire 2 to be detected changes in the future, the operator can make quick adjustments. The detection cylinder 50 and the detection rod 51 are connected to the upper clamping plate 52 via a connecting plate 55. The connecting plate 55 is fixed by a fixing bolt 550. The top end of the detection rod 51 is vertically inserted into the detection cylinder 50. A spring (not shown in the figure) is provided between the two. The spring is preferably a stainless steel compression spring to provide constant downward pressure. The operator selects a suitable contact detection disc 510 according to the sidewall width of the tire 2. The contact detection disc 510 is connected to the bottom end of the detection rod 51 via a thread to ensure replaceability. After installation, due to the preload of the spring, the lower end face of the contact detection disc 510 automatically abuts against the sidewall of the tire 2. The pressure can be adjusted by the spring stiffness to avoid excessive damage to the tire tread. After the drive motor 40 starts, it drives the detection mechanism 5 to rotate circumferentially around the axis of the tire 2. The contact detection disc 510 slides on the outer wall of the tire 2. Its surface can be covered with a soft material (such as rubber). When there is no bulge on the outer wall of the tire 2, the contact detection disc 510 slides smoothly, and there is no relative displacement between the detection rod 51 and the detection cylinder 50. Once a bulge appears on the outer wall of the tire 2 (for example, due to the breakage of the internal cord), the bulge will protrude. When the contact detection disc 510 moves to this position, it is pushed upward to overcome the spring force, causing the detection rod 51 and the detection cylinder 50 to slide relative to each other. The sliding displacement can be monitored by visual observation or by a sensor (such as a linear encoder). The operator can directly see the sudden jump of the detection rod 51. In order to avoid the contact detection disc 510 getting stuck with the bulge during the movement, the outer wall of the contact detection disc 510 can be rounded and chamfered. That is, the outer wall of the contact detection disc 510 is arc-shaped so that it can be smoothly lifted by the bulge when it comes into contact with it. To accurately record the location of the bulge, the operator can pause the drive motor 40 and use a marker to mark the side of the tire 2 along the outer edge of the contact inspection disc 510. The marking method can include color coding or numerical labels for easy subsequent identification. After the entire outer wall of the tire 2 is inspected, the data can be integrated into the quality management system, and the bulge area is sent to the next process for repair (such as hot patching or replacement). This mechanical contact inspection avoids the light dependence of machine vision, is especially suitable for dark or reflective tires, and has a low false positive rate.
