Description

Technical Field

[0001] This utility model relates to the field of tire cleaning technology, and in particular to a tire hair removal device. Background Technology

[0002] With the continuous development of tire manufacturing technology, tire hair removal, as an important step in the tire production process, has gradually become one of the key factors in improving product quality and production efficiency. Tire hair refers to the tiny rubber burrs generated during tire vulcanization due to contact with the mold. It not only affects the tire's appearance but can also lead to adverse effects in subsequent processes, such as uneven tread and reduced finished product quality. Therefore, removing tire hair from the tire surface is a necessary step to ensure tire quality.

[0003] Currently, traditional tire hair removal methods primarily rely on manual operation. Manual cleaning is not only inefficient but also heavily influenced by the operator's experience, easily leading to omissions or uneven cleaning results. Furthermore, manual cleaning poses safety hazards, especially during prolonged periods of high-intensity labor, potentially impacting worker health. To improve the efficiency and consistency of tire hair removal, many companies have begun introducing automated cleaning equipment. However, existing automated cleaning equipment generally suffers from poor adaptability, uneven cleaning results, and complex operation. Existing equipment is typically designed for specific tire sizes, offering poor adaptability to tires of different specifications and shapes, often requiring frequent adjustments or changes in equipment configuration. On the other hand, some equipment uses overly simplistic cleaning methods, failing to achieve uniform cleaning across all areas of the tire surface, potentially resulting in localized tire hair residue. Moreover, existing equipment often requires complex manual adjustments or significant human intervention, preventing fully automated cleaning and limiting its application in large-scale production. Utility Model Content

[0004] The purpose of this invention is to provide a tire hair removal device that solves the problems of low automated cleaning efficiency, poor adaptability, and complex operation in the existing technology.

[0005] To achieve the above objectives, this utility model provides a tire hair removal device, including a mounting frame, a tensioning shaft mechanism, a controller, and a robotic arm. The robotic arm is connected to the controller, which is mounted on a mounting side plate. The end of the mounting side plate is connected to the mounting frame, and the mounting frame is connected to the tensioning shaft mechanism.

[0006] Preferably, the tensioning shaft mechanism includes a tensioning shaft, a telescopic component, and a rotating component. The rotating component is connected to the telescopic component, and the telescopic component is connected to the tensioning shaft. Both the telescopic component and the rotating component are mounted on the mounting bracket.

[0007] Preferably, one end of the robotic arm is connected to a motor, and the other end of the robotic arm is connected to a scraper. Both the robotic arm and the motor are located on the upper part of the mounting side plate.

[0012] (1) Through highly automated design, it can completely replace the traditional manual cleaning method and significantly improve the efficiency of cleaning baby hair.

[0013] (2) The collaboration between the robotic arm and the scraper enables the equipment to clean a large number of tires in a short time, reducing manual intervention and thus improving the overall operating efficiency of the production line.

[0014] (3) The equipment has strong adaptability.

[0026] Example

[0027] Please see Figure 1-4 This utility model provides a tire hair removal device, including a mounting frame 1, a tensioning shaft mechanism, a controller, and a robotic arm 2. The robotic arm 2 is connected to the controller, which is mounted on a mounting side plate 3. The end of the mounting side plate 3 is connected to the mounting frame 1, and the mounting frame 1 is connected to the tensioning shaft mechanism.

[0028] The tensioning shaft mechanism is used to clamp and fix the tire 8, ensuring its stability during rotation. The tensioning shaft mechanism includes a tensioning shaft 4, a telescopic component 5, and a rotating component. The rotating component 5 is connected to the telescopic component, which in turn is connected to the tensioning shaft 4. Both the telescopic component 5 and the rotating component are mounted on the mounting bracket 1. The tensioning shaft 4 has an adjustable design to accommodate different tire sizes. By precisely controlling the clamping force on the tire 8, it is ensured that the tire 8 will not shift or loosen during rotation, thus guaranteeing the accuracy of tire hair removal. The rotating component drives the tensioning shaft 4 to rotate the tire 8, facilitating the removal of surface tire hair.

[0029] The rotating components adopt a modular design, including a power module, transmission module, monitoring module, and braking module. The power module uses a 400W servo motor with a rated speed of 3000rpm and a built-in 24-bit high-precision encoder, achieving a positioning accuracy of ±0.1°. The motor shaft is equipped with a cooling fan and a temperature protection switch, automatically reducing speed when the temperature exceeds 75℃.

[0030] The transmission module adopts a two-stage planetary gear reducer with a total reduction ratio of 15:1 and an output torque of up to 120 N·m. The input end of the reducer is connected to the motor via a flexible coupling, and the output end is connected to the tensioning shaft 4 via an involute spline. The spline specification is 8×42×8H / 8g as specified in GB / T3478.1-2008.

[0031] The detection module installs a non-contact torque sensor at the reducer output, with a range of 0-150 N·m, an accuracy of ±0.5% FS, and a sampling frequency of 1 kHz. The sensor signal is transmitted to the controller via a CAN bus.

[0032] Braking module: Equipped with an electromagnetic power failure brake, braking torque of 60 N·m, response time <50 ms, and conforms to ISO13849-1 safety standard.

[0033] One end of the robotic arm 2 is connected to a motor, and the other end is connected to the scraper 6. The robotic arm 2 is mounted on the upper part of the side plate and has a detachable design for easy replacement and maintenance. The robotic arm 2 is electrically driven and can automatically extend and retract according to the diameter of the tire 8. Through motor control, the moving speed and rotational force of the robotic arm 2 and the scraper 6 can be adjusted. The extension and retraction function of the robotic arm 2 ensures that the scraper 6 can adapt to tires 8 of different sizes, thereby guaranteeing the efficiency and consistency of the cleaning process.

[0034] The scraper 6 is connected to the robotic arm 2 and has an adjustable telescopic function. Driven by the robotic arm 2, the scraper 6 rotates and moves, evenly scraping away tire hairs along the surface of the tire 8 during the cleaning process. The end of the scraper 6 is serrated, and its material and shape are optimized to effectively remove fine tire hairs from the tire 8 surface without damaging it. The precise adjustment of the scraper 6 can adapt to different curved surfaces of the tire 8.

[0035] The controller can automatically adjust the position of the robotic arm 2 and the operating parameters of the scraper 6 according to the size and shape of the tire 8. Users can control the equipment via a touchscreen or remote operation, adjusting parameters to suit the cleaning needs of different tires 8. The controller also has an automatic detection function; the monitor 7 mounted on the side plate 3 can monitor the equipment's working status in real time, ensuring smooth cleaning. The rotation control system adopts a three-loop control strategy: Position loop: precise angle control based on encoder feedback; Speed ​​loop: fuzzy PID algorithm to adapt to the speed requirements of tires with different diameters; Torque loop: overload protection via a torque sensor.

[0036] Work process:

[0037] Tire 8 Loading: Place the tire 8 to be cleaned on the equipment's worktable. The tire 8 is fed into the equipment's tensioning shaft mechanism via a conveyor or manually. The tensioning shaft mechanism automatically adjusts the clamping force to fix the tire 8 to the equipment. A stable clamping state is formed between the tire 8 and the tensioning shaft 4, ensuring that the tire 8 does not shift during subsequent operations.

[0038] Equipment Initialization: The equipment controller is activated. Through the intelligent detection module, the controller automatically identifies the size, shape, and position of tire 8, and automatically adjusts the position of the robotic arm 2 and the extension length of the scraper 6 according to the tire 8 specifications, ensuring that the scraper 6 accurately contacts the surface of tire 8. The equipment will automatically perform calibration to ensure the smooth operation of the entire cleaning process.

[0039] Cleaning begins: The robotic arm 2 and scraper 6 are activated. The robotic arm 2 extends and retracts to the appropriate position according to the instructions of the control system, and drives the scraper 6 to scrape along the surface of the tire 8. The tire 8 starts to rotate via a rotating component, and the scraper 6 slides along a predetermined trajectory on the surface of the tire 8, scraping away the tire hair. The extension and retraction function of the scraper 6 ensures that it can adapt to different curvatures of the tire 8, ensuring the uniformity of the cleaning effect.

[0040] Real-time monitoring: The controller monitors the equipment's operating status in real time, including the extension and retraction position of the robotic arm 2, the working status of the scraper 6, and the rotation speed of the tire 8. If any abnormality is detected, such as the scraper 6 failing to fully contact the surface of the tire 8 or the scraper 6 applying excessive pressure, the controller will automatically adjust the operating parameters to ensure the cleaning process proceeds smoothly.

[0041] Cleaning complete: Once the tire hairs on the surface of tire 8 have been completely removed, the equipment will automatically stop the cleaning process. The controller will notify the operator that the cleaning is complete, the robotic arm 2 will automatically return to its original position, and the scraper 6 will stop working.

[0042] Tire 8 unloading: The equipment automatically releases the tensioning shaft 4 from the tire 8, and the tire 8 can be removed from the equipment by a conveyor or manually, and enter the next process or be inspected.

[0043] Equipment Reset: After completing a cleaning task, the equipment will automatically reset to prepare for the next tire 8 cleaning task. The controller will automatically detect the working status of the equipment to ensure that every part of the equipment is in normal working condition.

[0044] Therefore, this utility model employs the aforementioned tire hair removal equipment, which, through a highly automated design, can completely replace traditional manual cleaning methods, significantly improving tire hair removal efficiency. The collaboration between the robotic arm and the scraper enables the equipment to clean large batches of tires in a short time, reducing manual intervention and thus improving the overall operating efficiency of the production line. Compared with traditional manual cleaning methods, this new invention also effectively reduces workers' opportunities to come into contact with high-temperature tires or potentially dangerous parts, lowering safety hazards during operation, and making the equipment operation more stable, reducing the risk of malfunctions caused by human error and fatigue.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
