Description

Technical Field

[0001] This utility model relates to the field of tire processing and inspection, and in particular to a tire self-healing coating thickness detection device. Background Technology

[0002] In tire manufacturing, self-healing coating technology is a key element in improving tire safety performance. This coating can automatically seal punctures in the tread to prevent air leakage. However, the uniformity of coating thickness directly affects the sealing effect and driving safety. Traditional inspection methods mostly rely on manual handheld measuring equipment or fixed sampling inspection, which has obvious limitations: manual inspection is inefficient and easily affected by subjective factors, making it difficult to guarantee measurement accuracy; sampling inspection cannot cover the entire circumference of the tire's inner wall, which may lead to missed detections; although some automated equipment can achieve rotational inspection, it lacks adaptive guidance and fixing structures for different tire sizes, and during tire installation and positioning, it is easy to cause measurement data distortion due to displacement or tilting, or even scratch the coating surface.

[0003] Therefore, in order to address the above problems, a tire self-healing coating thickness detection device is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices during use, this utility model provides a tire self-healing coating thickness detection device.

Four springs are provided between the second mounting plate and the first mounting plate.

[0008] As a further preferred embodiment, an anti-tipping mechanism is also included. The anti-tipping mechanism includes a power source, which is mounted on the top of the workbench.

[0009] As a further preferred embodiment, the second rotating roller is located to the left of the first rotating roller.

[0010] As a further preferred option, the second mounting plate is a slanted structure with an flared design.

[0012] By adopting the above technical solution, this utility model has the following advantages:

Detailed Implementation

[0019] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0020] A tire self-healing coating thickness detection device, such as Figures 1-4 As shown, the system includes a worktable 1. A first rotating roller 2 is rotatably connected to the right side of the worktable 1, and a second rotating roller 3 is rotatably connected to the right side of the worktable 1. The second rotating roller 3 is located to the left of the first rotating roller 2. A motor 4 is installed at the rear right side of the worktable 1. The output shaft of the motor 4 is oriented forward and connected to the second rotating roller 3. A tire 5 is placed inside the worktable 1. An auxiliary guide mechanism 6 is provided on the right side of the worktable 1 to help the tire 5 enter the worktable 1. The auxiliary guide mechanism 6 includes a first mounting plate 61. Two symmetrical first mounting plates 61 are installed on the right side of the worktable 1. A second mounting plate 62 is provided on the inner side of each first mounting plate 61. The second mounting plates 62 are all inclined and have a flared design. Three contact rollers 63 are rotatably connected to the second mounting plates 62. The contact rollers 63 are used to assist the movement of the tire 5. Four springs 64 are provided between the second mounting plates 62 and the first mounting plates 61.

[0021] It also includes an anti-tipping mechanism 7, which includes a power source 71. The power source 71 is installed on the top of the workbench 1. A lead screw is connected to the output shaft of the power source 71. A mounting component 72 is threadedly connected to the lead screw. Four guide rods are provided on the mounting component 72. The guide rods are slidably connected to the workbench 1. An electric guide rail 73 is provided on the lower side of the mounting component 72. A clamping rod 74 is slidably connected to the electric guide rail 73. The clamping rod 74 can rotate on its own.

[0022] It should be noted that, firstly, the tire 5 to be tested is placed at the auxiliary guide mechanism 6 on the right side of the workbench 1. The second mounting plate 62 of this mechanism has an inclined and flared design, which can naturally guide the tire 5 into the testing area. When the tire 5 contacts the three contact rollers 63 on the second mounting plate 62, under the action of slight manual pushing or its own weight, the contact rollers 63 reduce frictional resistance by rotating, allowing the tire 5 to slide smoothly into the workbench 1. At this time, the four springs 64 between the second mounting plate 62 and the first mounting plate 61 undergo elastic deformation, and adaptively adjust the opening width according to the size of the tire 5. This ensures the passage of tires 5 of different specifications, and forms a flexible limit through the rebound force of the springs 64 to prevent the tire 5 from deviating during the guide process.

[0023] Once the tire 5 is fully positioned inside the workbench 1, the anti-tipping mechanism 7 is activated. The power source 71 (which can be a servo motor 4 or a stepper motor 4) drives the lead screw to rotate, causing the mounting part 72 to move downwards along the guide rod. The electric guide rail 73 on the lower side of the mounting part 72 descends synchronously, causing the two sets of clamping rollers 74 to move to the inner and outer edges of the tire 5 respectively. Then, the electric guide rail 73 is activated, driving the clamping rollers 74 to move towards each other along the tire circumference until they are tightly fitted to the tire sidewall. At this time, the clamping rollers 74's own rotation system is activated, and the friction force drives the tire 5 to make fine adjustments and positioning to ensure that the central axis of the tire 5 coincides with the axis of the rotating roller.

[0024] After positioning is completed, motor 4 starts and drives the second rotating roller 3 to rotate. Since the second rotating roller 3 supports the tire 5, a stable rotation drive system is formed, so that the tire 5 rotates at a constant speed. During the rotation of the tire 5, the inner wall coating of the tire is continuously scanned and detected by an external thickness detection sensor (such as a laser rangefinder or ultrasonic probe). This sensor can be installed on an adjustable bracket, and its detection head points to a specific area on the inner wall of the tire 5. The coating thickness data in the entire circumferential direction is obtained by rotational scanning. The detection data is transmitted to the processing system in real time. The algorithm analyzes the coating uniformity, whether there are defects or thickness deviations, etc. After the detection is completed, motor 4 stops running, the power source 71 of the anti-tipping mechanism 7 reverses to make the lead screw rise, and the clamping roller 74 resets with the electric guide rail 73 to release the fixation of the tire 5. The operator can easily take out the detected tire 5. The entire process is automated through the integration of the control system. The auxiliary guide mechanism 6 ensures that the tire 5 is quickly and accurately positioned, and the anti-tipping mechanism 7 effectively prevents the tire 5 from tipping or shifting when rotating at high speed, ensuring the accuracy and repeatability of the detection data.
